[0126] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0127] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0128] The present disclosure provides a cleaning device, which may be a self-moving cleaning device well known to those skilled in the art, such as a sweeping and mopping robot, or a handheld cleaning device having both sweeping and mopping functions. In an embodiment of the present disclosure where the cleaning device is a self-moving cleaning device, the self-moving cleaning device moves autonomously on a work surface and cleans the work surface. In an embodiment of the present disclosure where the cleaning device is a handheld floor scrubber, when a user uses the floor scrubber for cleaning, the user may push the floor scrubber to move on the work surface and clean the work surface.

[0129] The cleaning device disclosed in the present invention comprises a body, a dust brush device, a dust collection component, a floor scrubber component and a control unit. The body comprises a chassis component and a shell, and the chassis component is used to install various functional components required for the cleaning device; the dust brush device is arranged at the bottom of the chassis component and is configured to rotate relative to a working surface to clean the working surface; the dust collection component is arranged at the bottom of the chassis component and is configured to suck up solid waste on the working surface; the floor scrubber component is arranged at the bottom of the chassis component and is configured to contact the working surface to scrub the working surface; the control unit is configured to select the dust brush device and / or the dust collection component and / or the floor scrubber component to operate on the working surface based on the environmental information of the working surface.

[0130] In this way, during the cleaning process of the cleaning device of the present invention, the control unit can select one of the dust brush device, dust suction component, and floor scrubber component to work alone, or select two or three to work simultaneously, based on the environmental information of the working surface. Specifically, during the cleaning process of the cleaning device of the present invention, when it is necessary to clean soft surfaces such as carpets, the control unit can only control the dust brush device and dust suction component to work, and control the floor scrubber component to stop working, so as to avoid the floor scrubber component from contaminating the carpet. When it is necessary to clean hard surfaces such as floors, tiles or cement surfaces, the control unit can only control the dust brush device and dust suction component to work, and control the floor scrubber component to stop working, so as to avoid the floor scrubber component from wetting the working surface, causing the working surface to become slippery after being wetted, and ensure the safety of personnel walking. When it is necessary to clean and scrub hard surfaces such as floors, tiles or cement surfaces, the control unit can control the dust brush device, dust suction component, and floor scrubber component to work simultaneously, so as to clean and scrub the working surface, so as to perform deep cleaning on the working surface. When only hard surfaces such as floors, tiles or cement surfaces need to be dusted, the control unit can only control the dust brush device to work, so as to push and gather the solid garbage on the working surface.

[0131] It can be seen that the cleaning device disclosed in the present invention can automatically control the dust brush device, the dust suction component, and the floor washing component to work separately or simultaneously according to the environmental information of the working surface, thereby effectively meeting the various needs of users and improving the user experience.

[0132] For ease of understanding, refer to Figures 1 to 23 , the specific structure and working principle of the cleaning device disclosed in the present invention are explained in detail in combination with an embodiment.

[0133] like Figure 1 As shown, the present disclosure provides a cleaning device, which can be a self-moving cleaning device well known to those skilled in the art, such as a sweeping and mopping robot, or a handheld cleaning device having both sweeping and mopping functions. In an embodiment of the cleaning device of the present disclosure as a self-moving cleaning device, the self-moving cleaning device moves autonomously on a work surface and cleans the work surface. In an embodiment of the cleaning device of the present disclosure as a handheld floor scrubber, when a user uses the floor scrubber for cleaning, the user can push the floor scrubber to move on the work surface and clean the work surface.

[0134] like Figure 2 and Figure 3 As shown, the cleaning device of the present disclosure includes a body 1, a dust brush device 2, a dust suction component 3, a floor scrubbing component 4 and a control unit 82. Figure 4 and Figure 5As shown, the body 1 includes a chassis assembly 11 and a shell 12. The chassis assembly 11 is used to install various functional components required for the cleaning device; the shell 12 is used to protect the various functional components on the cleaning device of the present disclosure; and the control unit 82 is used to control the various functional components of the cleaning device to perform cleaning work.

[0135] like Figure 2 As shown, the dust brush device 2 is disposed at the bottom of the chassis assembly 11 and is configured to rotate relative to the work surface to clean the work surface. In one embodiment of the present disclosure, the dust brush device 2 of the present disclosure includes a roller brush assembly 21 and / or a side brush assembly 22.

[0136] Among them, Figure 6 , Figure 7 and Figure 8 As shown, in one embodiment of the present disclosure, the roller brush assembly 21 includes a roller brush bracket 211, a roller brush mechanism 212 and a first lifting mechanism 213; the roller brush bracket 211 is configured to be fixed to the bottom of the chassis assembly 11, so that the roller brush assembly 21 is installed at the bottom of the chassis assembly 11. The roller brush mechanism 212 is configured to be hinged to the roller brush bracket 211 through a first swing arm 214; the first lifting mechanism 213 is connected to the roller brush bracket 211, and is configured to drive the roller brush mechanism 212 to move in the height direction.

[0137] In this way, the roller brush mechanism 212 can rotate relative to the working surface to separate the solid waste on the working surface from the working surface. When the roller brush mechanism 212 is not needed to clean the working surface, the first lifting mechanism 213 can drive the roller brush mechanism 212 to move in the height direction relative to the roller brush bracket 211 through the first swing arm 214, so that the roller brush mechanism 212 can be separated from the working surface, which can reduce the movement resistance of the cleaning device when moving on the working surface, and avoid the friction between the roller brush mechanism 212 and the working surface to contaminate the cleaned working surface.

[0138] Specifically, the roller brush mechanism 212 includes a roller brush 2121 and a roller brush motor 2122 connected to the roller brush 2121, and the roller brush motor 2122 is used to drive the roller brush to rotate. Figure 5 As shown, in one embodiment of the present disclosure, a maintenance door 121 is provided at the bottom of the housing 12 of the cleaning device of the present disclosure. After the user opens the maintenance door 121, the roller brush 2121 can be quickly removed and replaced, so that the replacement of the roller brush 2121 can be made easier.

[0139] like Figure 2As shown, in one embodiment of the present disclosure, the side brush assembly 22 is located in front of the roller brush assembly 21, and is configured to be arranged on one side edge of the chassis assembly 11. When cleaning along the edge, the control unit 82 is configured to control the side brush assembly 22 to at least clean along the edge. That is, during the operation of the cleaning device of the present disclosure, when the cleaning device needs to clean edge areas such as corners, wall edges, and cabinet edges, the side brush assembly 22 can be rotated to be located on one side of the edge area. In this way, when the cleaning device moves along the edge, the side brush assembly 22 can be controlled to clean along the edge to clean the working surface of the edge area and remove solid waste on the working surface of the edge area, thereby avoiding omissions and effectively increasing the coverage cleaning area of ​​the cleaning device.

[0140] like Figure 2 and Figure 3 As shown, the dust collecting assembly 3 is disposed at the bottom of the chassis assembly 11 and is configured to collect solid waste on the working surface. Fig. 9 As shown, the dust collection assembly 3 includes a dust box bracket 31 and a dust box 32 disposed in the dust box bracket 31, wherein the dust box assembly is fixedly disposed on the chassis assembly 11, the air inlet end of the dust box 32 is connected to the dust suction port, the dust suction port is located on the rubber-coated fastener of the roller brush assembly 21, and the air outlet end is connected to the fan that provides power. The air inlet end of the dust box 32 is provided with a baffle 33, which is used to prevent the garbage in the dust box 32 from leaking out of the dust box when the dust collection assembly 3 is not working, and the air inlet end of the dust box 32 is provided with a windshield 34, which is used to prevent the fine and particulate matter in the dust box 32 from being sucked into the fan connected to the dust box 32 to avoid damage to the fan.

[0141] The floor scrubbing assembly 4 is disposed at the bottom of the chassis assembly 11 and is configured to contact the work surface to scrub the work surface. Fig.11 and Fig.12 As shown, in one embodiment of the present disclosure, the floor scrubbing assembly 4 of the present disclosure includes a floor scrubbing bracket 41, a floor scrubbing mechanism 42 and a second lifting mechanism 43. The floor scrubbing bracket 41 is configured to be fixed to the bottom of the chassis assembly 11; the floor scrubbing mechanism 42 is configured to be hinged to the floor scrubbing bracket 41 through a second swing arm 44; the second lifting mechanism 43 is connected to the floor scrubbing bracket 41 and is configured to drive the floor scrubbing mechanism 42 to move in the height direction. Specifically, the floor scrubbing mechanism 42 includes a cloth brush 421 and a cloth brush motor 422 connected to the cloth brush 421, and the cloth brush motor 422 is used to drive the cloth brush to rotate.

[0142] In this way, the floor scrubbing mechanism 42 can rotate relative to the work surface through the cloth brush 421 to wet and scrub the dirt on the work surface. When the floor scrubbing mechanism 42 is not needed to clean the work surface, the second lifting mechanism 43 can drive the floor scrubbing mechanism 42 to move in the height direction relative to the floor scrubbing bracket 41 through the second swing arm 44, so that the floor scrubbing mechanism 42 can be separated from the work surface, which can reduce the movement resistance of the cleaning device when moving on the work surface, and prevent the floor scrubbing mechanism 42 from contacting and contaminating the carpet.

[0143] In order to control the cleaning device disclosed in the present invention to walk autonomously on the working surface, as Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, driving wheels 111 are provided on opposite sides of the bottom of the chassis assembly 11 , and the driving wheels 111 are configured to drive the cleaning device to walk on a working surface.

[0144] Among them, the cleaning device of the present invention can control the rotation speed and rotation direction of the two driving wheels 111, so that the cleaning device of the present invention can move in a straight line or curve or turn on the spot on the working surface, so that the cleaning device of the present invention can clean everywhere on the working surface and meet the cleaning needs of the user.

[0145] To support the cleaning device of the present disclosure on a work surface, such as Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, a travel wheel 112 is provided on the front side of the chassis assembly 11, so that the travel wheel 112 and the two driving wheels 111 can jointly support the cleaning device of the present disclosure on the working surface. Figure 3 As shown, in one embodiment of the present disclosure, the travel wheel 112 of the present disclosure can be a universal wheel. In this way, when the cleaning device of the present disclosure turns on the work surface, the universal wheel can turn along with the overall turning of the cleaning device of the present disclosure, so that the cleaning device of the present disclosure is more flexible when turning, and the resistance of the cleaning device of the present disclosure when rotating on the work surface is effectively reduced.

[0146] Specifically, the control unit 82 is configured to select the dust brush device 2 and / or the dust collection component 3 and / or the floor scrubber component 4 to operate on the work surface based on the environmental information of the work surface. Specifically, the environmental information of the work surface can be divided into only two types: hard surface and soft surface, or can be further subdivided into specific materials. In this way, the control unit 82 can select part or all of the dust brush device 2 and / or the dust collection component 3 and / or the floor scrubber component 4 to operate on the work surface based on the environmental information of the work surface, thereby meeting the cleaning requirements.

[0147] In this way, in the process of cleaning the working surface of the cleaning equipment disclosed in the present invention, the control unit 82 can select one of the dust brush device 2, the dust suction component 3, and the floor scrubber component 4 to work alone, or select two or three to work simultaneously based on the environmental information of the working surface. Specifically, in the process of cleaning the working surface of the cleaning equipment disclosed in the present invention, when it is necessary to clean soft surfaces such as carpets, the control unit 82 can only control the dust brush device 2 and the dust suction component 3 to work, and control the floor scrubber component 4 to stop working, so as to avoid the floor scrubber component 4 from contaminating the carpet. When it is necessary to clean hard surfaces such as floors, tiles or cement surfaces, the control unit 82 can only control the dust brush device 2 and the dust suction component 3 to work, and control the floor scrubber component 4 to stop working, so as to avoid the floor scrubber component 4 from wetting the working surface, causing the working surface to be slippery after wetting, and ensure the safety of personnel walking. When it is necessary to clean and scrub hard surfaces such as floors, tiles or cement surfaces, the control unit 82 can control the dust brush device 2, the dust suction component 3, and the floor scrubber component 4 to work simultaneously, so as to clean and scrub the working surface, so as to perform deep cleaning on the working surface. When only hard surfaces such as floors, tiles or cement surfaces need to be dusted, the control unit 82 can only control the dust brush device 2 to work, so as to push and gather the solid garbage on the work surface.

[0148] It can be seen that the cleaning device disclosed in the present invention can automatically control the dust brush device 2, the dust suction component 3, and the floor washing component 4 to work separately or simultaneously according to the environmental information of the working surface, thereby effectively meeting various needs of users and improving the user experience.

[0149] It can be understood that in the cleaning device of the present invention, there is no need to manually replace the brush body of different materials according to the cleaning and mopping needs, thereby reducing the labor burden; and the dust brush device 2, the dust suction component 3, and the floor washing component 4 are all independent components and can be replaced separately, thereby making the maintenance of the cleaning device of the present invention more convenient.

[0150] In order to obtain the environmental information of the working surface, such as Fig.13 As shown, in one embodiment of the present disclosure, a detection sensor 131 is provided on the chassis assembly 11, and the detection sensor 131 is constructed to identify environmental information of the work surface, and the control unit 82 is configured to select the dust brush device 2 and / or the dust suction assembly 3 and / or the floor washing assembly 4 to operate on the work surface based on the environmental information obtained by the detection sensor 131.

[0151] Specifically, Figure 5 and Fig.13 As shown, the cleaning device of the present invention also includes a collision plate assembly 13, which is arranged at the front bottom of the chassis assembly 11. The detection sensor 131 can be arranged on the collision plate assembly 13, and after being installed on the chassis assembly 11, the detection sensor 131 can face the working surface and obtain the environmental information of the working surface by detecting sound and light signals.

[0152] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, a mode switching unit 141 is provided on the top of the chassis assembly 11 of the cleaning device of the present disclosure, and the control unit 82 is configured to select the dust brush device 2 and / or the dust suction assembly 3 and / or the floor scrubber assembly 4 to operate on the work surface in response to the mode switching unit 141. In this way, the cleaning device of the present disclosure can forcibly switch the dust brush device 2 and / or the dust suction assembly 3 and / or the floor scrubber assembly 4 to operate on the work surface according to manual needs, thereby better meeting the needs of users. Among them, the mode switching unit 141 can be in the form of a button, or in the form of a key or a knob, which is not limited here.

[0153] Among them, Figure 2 As shown, in one embodiment of the present disclosure, the side in the forward direction of the cleaning device is recorded as the front side, and the side away from the forward direction of the cleaning device is recorded as the rear side; the dust brush device 2, the dust suction assembly 3, and the floor washing assembly 4 are constructed to be arranged in sequence from front to back at the bottom of the chassis assembly 11.

[0154] In this way, during the operation of the cleaning device disclosed in the present invention, the dust brush device 2, the dust suction component 3, and the floor scrubber component 4 can sequentially clean, dust and scrub the work surface. After the dust brush device 2 separates the solid waste on the work surface from the work surface, the dust suction component 3 can suck the solid waste on the work surface into the dust box 32 of the dust suction component 3, and then the floor scrubber component 4 can wet and scrub the work surface, thereby thoroughly cleaning the work surface. It can be seen that in the cleaning device disclosed in the present invention, the arrangement order of the dust brush device 2, the dust suction component 3, and the floor scrubber component 4 is reasonable, which can not only clean the work surface, but also prevent the components from interfering with each other during operation.

[0155] Further, such as Figure 2 As shown, in one embodiment of the present disclosure, the dust suction assembly 3 is constructed to be located between the two driving wheels 111, so that the dust suction assembly 3 and the two driving wheels 111 can be arranged side by side, which can not only enable the dust suction assembly 3 to effectively absorb solid waste on the working surface, but also effectively reduce the extension length of the cleaning equipment in its forward direction, making the structure of the cleaning equipment more compact.

[0156] like Figure 2 As shown, in one embodiment of the present disclosure, the roller brush assembly 21 is configured to be arranged in front of the driving wheel 111. In this way, the roller brush assembly 21 can be located in front of the dust collection assembly 3, and at least one side of the roller brush assembly 21 can be extended to a position flush with the driving wheel 111 or beyond the driving wheel 111, thereby increasing the coverage area of ​​the roller brush assembly 21.

[0157] Similar, such as Figure 2 As shown, in one embodiment of the present disclosure, the floor scrubbing assembly 4 is constructed to be arranged at a position located on the rear side of the driving wheel 111; in this way, the floor scrubbing assembly 4 can effectively wet the working surface on which the scrubbing roller brush assembly 21 and the dust suction assembly 3 have completed operation, and at least one side of the floor scrubbing assembly 4 can be extended to a position flush with the driving wheel 111 or beyond the driving wheel 111, thereby increasing the coverage area of ​​the floor scrubbing assembly 4.

[0158] Specifically, Fig.14 As shown, in one embodiment of the present disclosure, the side brush assembly 22 includes a side brush bracket 225 for fixing at the bottom of the chassis assembly 11 and a side brush 222 controlled by a side brush motor 221; the side brush includes a bristle holder 2221, and bristles 2222 distributed along the circumferential direction and extending toward the working surface on the bristle holder 2221. Thus, during the operation of the side brush assembly 22 of the present disclosure, the side brush motor 221 can drive the side brush 222 to rotate, thereby enabling the bristles on the side brush 222 to rotate relative to the working surface to clean the solid waste on the working surface.

[0159] Further, such as Fig.14 As shown, in one embodiment of the present disclosure, a guide portion 223 is provided between the side brush 222 and the travel wheel 112, and the bristles 2222 are constructed to deform after rotating and contacting the guide portion 223, and to restore the deformation after leaving the guide portion 223; the guide portion 223 can effectively press the bristles 2222 against the work surface, so that the bristles 2222 are in close contact with the work surface to improve the cleaning effect of the side brush 222, and keep the bristles 2222 away from the travel wheel 112, so as to prevent the bristles 2222 from being pressed under the travel wheel 112 and causing the side brush 222 to be unable to rotate normally.

[0160] Among them, Fig.14 As shown, in one embodiment of the present disclosure, a blocking portion 224 extending outward is provided at a position above the bristles 2222 on the bristle holder 2221. By providing the blocking portion 224, it is possible to effectively prevent hair, thread ends and other objects entangled on the side brush 222 from moving upward and entangled on the side brush motor 221, thereby damaging the side brush motor 221, thereby ensuring that the side brush assembly 22 of the present disclosure can work normally.

[0161] Among them, Fig.15 , Fig.16 and Fig.17 As shown, in one embodiment of the present disclosure, a box assembly 7 is arranged above the chassis assembly 11, and the box assembly 7 includes a clean water tank 71 and a dirty water tank 72, wherein the clean water tank 71 is used to contain clean water required for wetting the cloth brush 421, and the dirty water tank 72 is used to contain dirt sucked from the working surface by the cleaning device of the present disclosure.

[0162] Specifically, Fig.16 As shown, in one embodiment of the present disclosure, the top of the clean water tank 71 is constructed to be recessed downward to form a plug-in cavity 711; the sewage tank 72 is constructed to be installed in the plug-in cavity 711 in a plug-in manner; a handle 721 is rotatably connected to the top of the sewage tank 72, and the handle 721 is constructed to be able to rotate to the side wall of the sewage tank 72.

[0163] By forming a plug-in cavity 711 at the top of the clean water tank 71, the sewage tank 72 can be conveniently installed in the plug-in cavity 711 by plugging. Moreover, since the top of the sewage tank 72 is rotatably connected with a handle 721, the handle 721 can be rotated to the side wall of the sewage tank 72. In this way, it is convenient for the user to rotate and pull the handle 721 upward to remove the sewage tank 72 from the plug-in cavity 711 on the clean water tank 71, and after the sewage tank 72 is placed in the plug-in cavity 711 on the clean water tank 71, the handle 721 can be rotated to a horizontal position and then stored in the housing 12 of the cleaning device.

[0164] Further, such as Fig.15 , Fig.16 and Fig.17 As shown, in one embodiment of the present disclosure, the box assembly 7 further includes a cleaning liquid tank 73, and a step groove is provided on the clean water tank 71 at the front side of the sewage tank 72, and the cleaning liquid tank 73 is configured to be installed in the step groove. Since the clean water tank 71 is provided with a step groove at the front side of the sewage tank 72, it is convenient for the cleaning liquid tank 73 to be installed in the step groove, and after the cleaning liquid tank 73 is installed in the step groove, it is flush with the upper surface of the sewage tank 72, so that the space in the housing 12 of the cleaning device can be effectively utilized, making the structure of the cleaning device more compact.

[0165] Specifically, the cleaning equipment disclosed in the present invention also includes a conveying component, which may include a pipeline connected to a clean water tank 71 and a cleaning liquid tank 73, and a conveying pump arranged on the pipeline. The conveying pump is used to spray the mixed cleaning water onto the work surface and / or the cloth brush 421 of the floor scrubbing component 4 after the clean water in the clean water tank 71 and the cleaning liquid in the cleaning liquid tank 73 are merged.

[0166] Specifically, Fig.15 , Fig.16 and Fig.17As shown, in one embodiment of the present disclosure, the housing 12 of the cleaning device of the present disclosure includes an upper flip cover 15, which is rotatably arranged above the box assembly 7 of the present disclosure. When the user manually replaces the sewage tank 72 or the cleaning liquid tank 73, the user can manually open the flip cover and take out the sewage tank 72 or the cleaning liquid tank 73; after placing the sewage tank 72 or the cleaning liquid tank 73, the flip cover can be manually closed, so that the sewage tank 72 or the cleaning liquid tank 73 of the present disclosure can be covered with the flip cover, making the cleaning device of the present disclosure more concise and beautiful.

[0167] In one embodiment of the present disclosure, the cleaning device of the present disclosure further includes a push rod assembly 5 , a power device 6 , a circuit board assembly 8 and a front sensor assembly 9 .

[0168] Among them, Fig.18 As shown, the push rod assembly 5 includes a push rod bracket 51 connected to the chassis assembly 11 and configured to extend upward, and a push rod 52 is movably disposed on the push rod bracket 51. Fig.19 As shown, the user can pull the push rod out of the push rod bracket 51, and push the cleaning device of the present disclosure on the work surface by holding the push rod 52. Furthermore, a magnet can be provided on the push rod 52, and a magnetic field detection unit can be provided on the push rod bracket 51, so that after the user pulls the push rod 52 out of the push rod bracket 51, the cleaning device of the present disclosure can automatically switch to the manual mode and no longer move autonomously on the work surface.

[0169] like Fig.18 As shown, in one embodiment of the present disclosure, a rear sensor bracket 53 may be provided on the push rod bracket 51, and a rear sensor 54 for detecting the rear side of the cleaning device and a charging electrode 55 for charging the cleaning device of the present disclosure may be provided on the rear sensor bracket 53 of the present disclosure. Furthermore, an automatic sewage outlet may be provided on the rear sensor bracket 53 of the present disclosure, and the automatic sewage outlet may be connected to the sewage tank 72, so that the cleaning device of the present disclosure can also achieve automatic sewage discharge when docking with the base station 90.

[0170] like Fig. 20 and Fig.21 As shown, the power device 6 includes a power bracket 61 connected to the chassis assembly 11 and configured to extend upward, and a power assembly 62 disposed on the power bracket 61. The power device 6 is used to provide power to the dust collection assembly 3 and the floor scrubbing assembly 4, so as to suck the solid garbage on the working surface into the dust box 32 of the dust collection assembly 3, and to suck the dirt on the working surface into the sewage bucket.

[0171] like Fig. 22 As shown, the circuit board assembly 8 includes a circuit board bracket 81 connected to the chassis assembly 11 and configured to extend upward, and also includes a circuit board mounted on the circuit board bracket 81 , and the control unit 82 of the present disclosure can be disposed on the circuit board.

[0172] like Fig.23 As shown, the front sensor assembly 9 includes a front sensor bracket 91 connected to the chassis assembly 11 and configured to extend upward; a front sensor 92 for detecting the front side of the cleaning device may be provided on the front sensor bracket 91 .

[0173] Among them, the front sensor assembly 9, the circuit board assembly 8, the box assembly 7, the power device 6, and the push rod assembly 5 are arranged from front to back on the chassis assembly 11. In this way, the front and rear structural layers of the cleaning device disclosed in the present invention can be cleaned, which is convenient for the installation and maintenance of each structure.

[0174] Specifically, Fig. 20 and Fig.21 As shown, in one embodiment of the present disclosure, the power assembly 62 includes a first fan 621, a second fan 622 and a silencer mechanism 623, the first fan 621 is configured to form a negative pressure for the floor washing assembly 4, and the second fan 622 is configured to form a negative pressure for the dust collection assembly 3; the silencer mechanism 623 is connected to the second fan 622.

[0175] Specifically, the floor washing component 4 is provided with a sewage suction port, the sewage bucket is connected to the sewage suction port, and the first fan 621 can form a negative pressure in the sewage bucket, so that the dirt on the working surface can be sucked into the sewage bucket. Similarly, the dust suction port is provided on the dust suction component 3, the dust box 32 of the dust suction component 3 is connected to the dust suction port, and the second fan 622 can form a negative pressure in the dust box 32, so that the solid garbage on the working surface can be sucked into the sewage bucket. Silencing cotton is provided in the silencer mechanism 623. Since the silencer mechanism 623 is connected to the second fan 622, when the airflow formed by the second fan 622 flows through the silencer mechanism 623, the silencer cotton can effectively reduce the noise generated by the airflow formed by the second fan 622. However, since the airflow formed by the first fan 621 contains water vapor, the silencer mechanism 623 containing silencer cotton cannot be used for noise reduction. Therefore, Fig.21 As shown, an expansion portion may be provided on the air outlet passage of the first fan 621 to reduce the noise generated by the first fan 621 .

[0176] like Fig. 20 and Fig.21As shown, in one embodiment of the present disclosure, the first fan 621 and the second fan 622 are coaxially arranged and are configured to be horizontally placed between the box assembly 7 and the push rod assembly 5; the silencer mechanism 623 is configured to be horizontally placed above the first fan 621 and is configured to be connected to the downstream of the second fan 622. Since the first fan 621 and the second fan 622 are coaxially arranged and are horizontally placed between the box assembly 7 and the push rod assembly 5, and the silencer mechanism 623 is horizontally placed above the first fan 621, the space occupied by the first fan 621 and the second fan 622 can be effectively reduced, making the structure of the power assembly 62 more compact.

[0177] like Fig.23 As shown, in the cleaning device of the present disclosure, the front sensor 92 may include a front upper RGBD sensor 921, a front lower RGBD sensor 922 and a DTOF sensor 923 (direct measurement time of flight sensor), and the rear sensor 54 may be a rear RGBD sensor. The DTOF sensor 923 is disposed on the laser seat and is disposed on the laser fixing frame by adjusting screws, and the laser fixing frame is fixed on the chassis assembly 11. The DTOF sensor 923 can be adjusted horizontally by adjusting screws to ensure that the laser line of the DTOF sensor 923 is kept horizontal with the working surface.

[0178] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, the housing 12 of the cleaning device of the present disclosure is also provided with a front left ultrasonic sensor 161, a front right ultrasonic sensor 162, a left ultrasonic sensor 163 and a right ultrasonic sensor 164, and the control unit 82 of the present disclosure can perform autonomous walking, path planning and navigation obstacle avoidance through various RGBD sensors, DTOF sensors 923 and ultrasonic sensors. Fig.13 As shown, the collision plate assembly 13 of the present disclosure may be provided with an air pressure sensor 132, and the air pressure sensor 132 can provide feedback on the collision with the obstacle through pressure changes after colliding with the obstacle. Fig.13 As shown, the impact plate assembly 13 of the present invention may also be provided with an anti-drop sensor 133, which is used to detect the distance from the working surface to avoid falling from steps or the like during the operation of the cleaning device of the present invention.

[0179] like Figure 4 and Figure 5 As shown, a front left position light 171, a front right position light 172, a rear left position light 173 and a rear right position light 174 are also provided on the housing 12 of the cleaning device of the present disclosure to illuminate when in working state to indicate that the cleaning device is operating.

[0180] like Fig.10As shown, in order to supply power to the various components of the cleaning device of the present disclosure, the cleaning device of the present disclosure further includes a power supply component 10, which is electrically connected to the various components on the cleaning device of the present disclosure to supply power to the various components of the cleaning device. It is understandable that the power supply component 10 is electrically connected to the charging electrode 55 of the rear sensor bracket 53. Fig.10 As shown, in one embodiment of the present disclosure, a manual charging port 101 is provided on the cleaning device of the present disclosure, and a charging door is provided at a position of the shell 12 corresponding to the manual charging port 101. When the user needs to manually charge the cleaning device, the user only needs to open the charging door and connect the charging cable to the manual charging port 101 to manually charge the cleaning device.

[0181] It can be understood that in one embodiment of the present disclosure, various components such as a power button 142, an emergency stop button 143, a key socket 144 and a display screen 18 can also be set on the housing 12 of the cleaning device of the present disclosure. The key socket 144 can enable the cleaning device of the present disclosure to work normally only when the correct key is inserted. The emergency stop button 143 is used to control the emergency stop of the cleaning device of the present disclosure, and the display screen 18 is used to display the working status information of the cleaning device of the present disclosure.

[0182] Application Scenario

[0183] The present disclosure provides a cleaning device, which may be a self-moving cleaning device well known to those skilled in the art, such as a sweeping and mopping robot, or a handheld cleaning device having both sweeping and mopping functions. In an embodiment of the present disclosure where the cleaning device is a self-moving cleaning device, the self-moving cleaning device moves autonomously on a work surface and cleans the work surface. In an embodiment of the present disclosure where the cleaning device is a handheld floor scrubber, when a user uses the floor scrubber for cleaning, the user may push the floor scrubber to move on the work surface and clean the work surface.

[0184] The cleaning device disclosed in the present invention comprises a body 1, a dust brush device 2, a dust collection component 3, a floor scrubber component 4 and a control unit 82. The body 1 comprises a chassis component 11 and a housing 12, wherein the chassis component 11 is used to install various functional components required for the cleaning device; the dust brush device 2 is arranged at the bottom of the chassis component 11 and is configured to rotate relative to the working surface to clean the working surface; the dust collection component 3 is arranged at the bottom of the chassis component 11 and is configured to suck solid waste on the working surface; the floor scrubber component 4 is arranged at the bottom of the chassis component 11 and is configured to contact the working surface to scrub the working surface; the control unit 82 is configured to select the dust brush device 2 and / or the dust collection component 3 and / or the floor scrubber component 4 to operate on the working surface based on the environmental information of the working surface.

[0185] In this way, in the process of cleaning the working surface of the cleaning equipment disclosed in the present invention, the control unit 82 can select one of the dust brush device 2, the dust suction component 3, and the floor scrubber component 4 to work alone, or select two or three to work simultaneously based on the environmental information of the working surface. Specifically, in the process of cleaning the working surface of the cleaning equipment disclosed in the present invention, when it is necessary to clean soft surfaces such as carpets, the control unit 82 can only control the dust brush device 2 and the dust suction component 3 to work, and control the floor scrubber component 4 to stop working, so as to avoid the floor scrubber component 4 from contaminating the carpet. When it is necessary to clean hard surfaces such as floors, tiles or cement surfaces, the control unit 82 can only control the dust brush device 2 and the dust suction component 3 to work, and control the floor scrubber component 4 to stop working, so as to avoid the floor scrubber component 4 from wetting the working surface, causing the working surface to be slippery after wetting, and ensure the safety of personnel walking. When it is necessary to clean and scrub hard surfaces such as floors, tiles or cement surfaces, the control unit 82 can control the dust brush device 2, the dust suction component 3, and the floor scrubber component 4 to work simultaneously, so as to clean and scrub the working surface, so as to perform deep cleaning on the working surface. When only hard surfaces such as floors, tiles or cement surfaces need to be dusted, the control unit 82 can only control the dust brush device 2 to work, so as to push and gather the solid garbage on the work surface.

[0186] It can be seen that the cleaning device disclosed in the present invention can automatically control the dust brush device 2, the dust suction component 3, and the floor washing component 4 to work separately or simultaneously according to the environmental information of the working surface, thereby effectively meeting various needs of users and improving the user experience.

[0187] See also Figure 24 to Figure 27 The embodiment of the present disclosure further provides a cleaning robot 1a, which is a self-propelled robot with a cleaning function, such as a sweeping robot or a sweeping and mopping multifunctional compound machine. The cleaning robot 1a provided in this embodiment includes a host 100a and a lifting mechanism 200a, wherein a control module is provided in the host 100a, and a walking mechanism is provided at the bottom of the host. The control module can actively or passively execute one or more cleaning modes through built-in operation instructions or receiving operation signals from the outside, and correspondingly drive the walking mechanism and the lifting mechanism 200a to work.

[0188] The lifting mechanism 200a includes a fixed seat 10a, a floating bracket 20a, a linkage assembly 30a and a driving assembly 40a. The fixed seat 10a can be connected to the main machine 100a by means of screw locks or welding, for example, fixed at a position adjacent to the bottom of the main machine 100a. The floating bracket 20a is arranged below the fixed seat 10a through the linkage assembly 30a, and partially or completely overlaps with the fixed seat 10a in the projection direction of the fixed seat 10a. The floating bracket 20a is used to set a cleaning assembly 70a, such as a detachable rear cloth brush or other forms of mopping parts, etc., for removing dust, dirt and debris on the ground.

[0189] The linkage assembly 30a is connected between the fixed seat 10a and the floating bracket 20a, and structurally, it can switch between a folded state and an unfolded state, wherein when the linkage assembly 30a is in the folded state, the floating bracket 20a is close to the fixed seat 10a, and when the linkage assembly 30a is in the unfolded state, the floating bracket 20a is away from the fixed seat 10a. It can be understood that in other embodiments of the present disclosure, the linkage assembly 30a can also be directly connected between the corresponding connection mechanism on the main unit 100a and the floating bracket 20a, and the setting of the fixed seat 10a is omitted in the lifting mechanism 200a. Therefore, although the following embodiments are illustrated by taking the lifting mechanism 200a including the fixed seat 10a as an example, it is not limited to this.

[0190] The driving component 40a is connected between the main unit 100a and the linkage component 30a, and is used to drive the linkage component 30a to switch between a folded state and an unfolded state, so that the linkage component 30a drives the floating bracket 20a to rise relative to the main unit 100a and move closer to the fixed base 10a, or to descend toward the ground to be cleaned and move away from the fixed base 10a.

[0191] Among them, since the driving component 40a drives the linkage component 30a, the lifting stroke of the floating bracket 20a can be adjusted synchronously. Therefore, it has high transmission accuracy, so that the lifting height of the cleaning component 70a is controlled within an appropriate range, and can better act on the ground, thereby achieving the purpose of cleaning and improving cleaning efficiency. At the same time, after the cleaning work is completed, the cleaning component 70a can maintain a predetermined distance from the ground, avoiding the cleaning component 70a from contacting the cleaned ground and causing secondary pollution.

[0192] In more detail, in some embodiments of the present disclosure, the linkage assembly 30a includes a first link 31a and a second link 32a. The two opposite ends of the first link 31a are movably connected to the fixed seat 10a and the floating bracket 20a respectively. The second link 32a is connected to the fixed seat 10a and is pivotally connected to the first link 31a. In this way, the first link 31a can pivot relative to the second link 32a and swing relative to each other, so that the linkage assembly 30a can achieve the function of folding and unfolding in structure.

[0193] The driving assembly 40a is connected between the mainframe 100a and the first connecting rod 31a to apply a driving force to the first connecting rod 31a in the first direction. When the driving assembly 40a drives the first connecting rod 31a to operate, the first connecting rod 31a can swing relative to the second connecting rod 32a and drive the floating bracket 20a to rise or fall along the second direction. The first direction and the second direction can be intersecting horizontal directions and vertical directions, but are not limited thereto. In other embodiments of the present disclosure, the first direction and the second direction can also be opposite directions on the same vertical axis.

[0194] In some embodiments of the present disclosure, the first connecting rod 31a includes an active end 311a and a driven end 312a relative to each other. The active end 311a is movably disposed on the fixed seat 10a, the driven end 312a is pivoted to the floating bracket 20a, and the second connecting rod 32a is pivoted between the active end 311a and the driven end 312a. For example, it is pivoted to the central area of ​​the first connecting rod 31a. In certain embodiments of the present disclosure, the lifting stroke of the floating bracket 20a can also be adjusted accordingly by adjusting the pivot position of the second connecting rod 32a between the active end 311a and the driven end 312a.

[0195] The driving assembly 40a is connected to the active end 311a of the first connecting rod 31a, and is used to drive the active end 311a to move on the fixed seat 10a, and its movement mode includes sliding and rotating. It is worth mentioning that when the active end 311a moves, it can synchronously drive the driven end 312a to pull the floating bracket 20a toward the fixed seat 10a, so that the floating bracket 20a forms an ascending state, or synchronously drive the driven end 312a to push the floating bracket 20a away from the fixed seat 10a, so that the floating bracket 20a forms a descending state.

[0196] Similarly, the second connecting rod 32a includes a first end 321a and a second end 322a opposite to each other, and a rotating shaft portion 323a between the first end 321a and the second end 322a, wherein the first end 321a and the rotating shaft portion 323a are pivotally connected to the fixing seat 10a and the first connecting rod 31a respectively, and the second end 322a is movably connected to the floating bracket 20a. In this way, when the first connecting rod 31a is driven by the driving assembly 40a, the rotating shaft portion 323a can swing with the second connecting rod 32a, and the second end 322a of the second connecting rod 32a can move synchronously on the floating bracket 20a, such as sliding and rotating, and approach or move away from the driven end 312a of the first connecting rod 31a. Among them, when the second end 322a of the second connecting rod 32a and the driven end 312a of the first connecting rod 31a are close to each other, the linkage assembly 30a is in an expanded state in the vertical axis, driving the floating bracket 20a to descend; and when the second end 322a of the second connecting rod 32a and the driven end 312a of the first connecting rod 31a are away from each other, the linkage assembly 30a is in a folded state in the vertical axis, lifting the floating bracket 20a.

[0197] It is worth mentioning that in some embodiments of the present disclosure, ball bearings or bushings may be but are not limited to be set at the pivot positions of the active end 311a, the driven end 312a, the first end 321a, the second end 322a and the shaft portion 323a, respectively, to provide a low-friction and smooth rotation effect.

[0198] In addition, in the disclosed embodiment, the fixed seat 10a further includes a first sliding groove 11a and a first slide rail 12a disposed in the first sliding groove 11a. A slidable first slider 33a is disposed on the first slide rail 12a, which may be disposed in pairs with the first slide rail 12a and is a part of the fixed seat 10a, or a part of the linkage assembly 30a. For the convenience of description, the present embodiment is illustrated by the first slider 33a correspondingly disposed on the linkage assembly 30a, but is not limited thereto. The first slider 33a is movably disposed on the first slide rail 12a, for example, the main body of the first slider 33a is sleeved on the first slide rail 12a, and the active end 311a of the first connecting rod 31a is pivotally connected to the side of the first slider 33a, and the driven end 312a is pivotally connected to the floating bracket 20a, so that the first slider 33a can slide back and forth in the first sliding groove 11a and drive the active end 311a to perform linear motion. The driving assembly 40a is connected to the first slider 33a to push the first slider 33a to move in the first sliding slot 11a. It is understandable that when the driving assembly 40a pushes the first slider 33a to move, the active end 311a moves with the first slider 33a and rotates relative to the first slider 33a as the position changes.

[0199] Similarly, the floating bracket 20a also includes a second sliding groove 21a and a second slide rail 22a disposed in the second sliding groove 21a, and the linkage assembly 30a is correspondingly provided with a second slider 34a. The main body of the second slider 34a is sleeved on the second slide rail 22a, and the second end 322a is pivoted on the side of the second slider 34a, so that the second slider 34a can slide back and forth in the second sliding groove 21a and drive the second end 322a to perform linear motion. In this way, the second end 322a can move with the second slider 34a and rotate relative to the second slider 34a as the position changes.

[0200] For example, the rotating shaft portion 323a is located in the central area of ​​the second connecting rod 32a and is pivotally connected to the central area of ​​the first connecting rod 31a, so that the first connecting rod 31a and the second connecting rod 32a form a symmetrical cross arm similar to a scissor. When the first slider 33a is pushed by the driving assembly 40a, the active end 311a moves on the first slide rail 12a along with the first slider 33a, and swings around the first slider 33a as the axis as the sliding position changes. At the same time, the second connecting rod 32a is linked to the first connecting rod 31a to produce a symmetrical swing, so that the second end 322a moves and rotates relatively with the second slider 34a on the second slide rail 22a. Therefore, the floating bracket 20a is driven to rise or fall by the mutual swing of the first connecting rod 31a and the second connecting rod 32a. In this way, under the push of the driving component 40a, the active end 311a and the first end 321a can move relatively away from or closer to each other, and link the second end 322a and the driven end 312a to move relatively away from or closer to each other, so that the first connecting rod 31a and the second connecting rod 32a form a folded state or an unfolded state, thereby driving the floating bracket 20a to rise or fall stably.

[0201] In some embodiments, the first connecting rod 31a and the second connecting rod 32a can also be arranged in pairs on the opposite sides of the fixed seat 10a and the floating bracket 20a to improve the balance and stability of the linkage assembly 30a. At the same time, it can be understood that in other embodiments, the first slider 33a and / or the second slider 34a can be provided with a linear bearing or a bushing to reduce the friction of the first slider 33a and the second slider 34a when they move on the corresponding slide rails, thereby providing a smooth and smooth linear sliding effect. For example, in this embodiment, the first slider 33a is provided with a first linear bearing 51a, and the second slider 34a is provided with a second linear bearing 52a, so that the first slider 33a and the second slider 34a are respectively sleeved on the corresponding first slide rail 12a and the second slide rail 22a through the first linear bearing 51a and the second linear bearing 52a, so that the rolling friction of the linear bearing on the slide rail can be used to reduce the jamming and shaking of the slider when sliding on the slide rail, and at the same time avoid the problem of wear between the two due to dry friction.

[0202] In some embodiments of the present disclosure, the driving assembly 40a further includes a power source 41a, a push rod 42a, and a power source fixing seat 45a. The two opposite ends of the push rod 42a are respectively connected to the power source 41a and the first slider 33a, and the power source fixing seat 45a is arranged at the other end of the power source 41a relative to the push rod 42a, so as to fix the power source 41a on the host 100a, so that the power source 41a is connected between the host 100a and the push rod 42a. The power source 41a can be, but is not limited to, a motor or an electric cylinder, so as to drive the push rod 42a to extend or retract, so as to drive the first slider 33a to move along the first slide rail 12a. It is worth mentioning that in this embodiment, when the push rod 42a is extended, the active end 311a of the first link 31a is close to the first end 321a of the second link 32a, and the second end 322a of the second link 32a is close to the driven end 312a of the first link 31a, so that the first link 31a and the second link 32a are in an unfolded state, driving the floating bracket 20a to descend. When the push rod 42a is retracted, the active end 311a is away from the first end 321a, and the second end 322a is away from the driven end 312a, so that the first link 31a and the second link 32a are in a folded state, driving the floating bracket 20a to ascend.

[0203] In addition, in some embodiments, a limit shaft 421a and a first buffer 422a are further provided at one end of the push rod 42a away from the power source 41a. The first slider 33a is provided with a through hole 331a, the tail end of the limit shaft 421a is connected to the push rod 42a, the head end passes through the through hole 331a and is provided with a limit portion 4211a (for example, the limit portion 4211a radially protrudes from the head end of the limit shaft 421a and is larger than the aperture of the through hole 331a to prevent the limit shaft 421a from detaching from the first slider 33a through the through hole 331a). The first buffer 422a can be, but is not limited to, a spring, which is sleeved on the limit shaft 421a and is located between the push rod 42a and the first slider 33a. In this way, the limiting portion 4211a and the first buffer member 422a can respectively push the first slider 33a to the initial position P2a and the working position P1a, so that the first slider 33a reciprocates between the initial position P2a and the working position P1a, and drives the first connecting rod 31a to swing relative to the second connecting rod 32a.

[0204] like Fig.26 and Fig. 27As shown, when the power source 41a drives the push rod 42a to extend the first length L1a, the limit shaft 421a can be pushed to move relative to the first slider 33a, and the first buffer 422a pushes the first slider 33a in the first sliding groove 11a, so that the first slider 33a moves away from the power source 41a to the working position P1a. At this time, the linkage assembly 30a drives the floating bracket 20a to descend, so that the cleaning assembly 70a contacts the ground and cleans. When the power source 41a drives the push rod 42a to retract, the limit shaft 421a can be pulled to move relative to the first slider 33a, and the limit portion 4211a pushes the first slider 33a in the first sliding groove 11a, so that the first slider 33a moves toward the power source 41a to the initial position P2a (that is, the initial position P2a). Fig. 27 The status is restored to Fig.26 At this time, the linkage assembly 30a drives the floating bracket 20a to rise, so that the cleaning assembly 70a leaves the ground.

[0205] It is worth mentioning that, during the process of the first buffer member 422a pushing the first slider 33a, the first buffer member 422a can provide a buffering effect through its elasticity, effectively reducing the impact and vibration between mechanical components, making the pushing process smoother.

[0206] When the first slider 33a is at the working position P1a, the cleaning assembly 70a contacts the ground. If the push rod 42a continues to extend, the first slider 33a will push and compress the first buffer 422a and move toward the push rod 42a, so that the floating bracket 20a will not continue to descend, thereby preventing the cleaning assembly 70a from being damaged by excessively squeezing the ground. Fig. 27 and Fig.28 As shown, when the first slider 33a is at the working position P1a, if the push rod 42a continues to extend from the first length L1a to the second length L2a, the first slider 33a will move toward the push rod 42a to compress the first buffer 422a, so that the floating bracket 20a remains stationary.

[0207] In some other embodiments of the present disclosure, a second buffer 423a is further provided on the limiting shaft 421a. The second buffer 423a may be, but is not limited to, another spring, which is sleeved on the limiting shaft 421a and located between the first slider 33a and the limiting portion 4211a. It should be noted that the function of the first buffer 422a and the second buffer 423a is to maintain the first slider 33a at the working position P1a by elastic force in the absence of external force.

[0208] In addition, when the first slider 33a is subjected to an external force at the working position P1a, the first slider 33a can move relative to the limit shaft 421a at the working position P1a through the elastic force of the first buffer 422a, thereby sliding on the first slide rail 12a, and compressing the first buffer 422a or the second buffer 423a according to the direction of the external force, thereby driving the floating bracket 20a to float up and down relative to the fixed seat 10a. Alternatively, when the external force disappears, the elastic force of the first buffer 422a and the second buffer 423a can push against the first slider 33a, so that the first slider 33a slides and returns to the working position P1a.

[0209] like Fig.29 and Fig.30 As shown, when the first slider 33a is pushed to the working position P1a and the cleaning component 70a contacts the ground, if it encounters an obstacle 75a, the floating bracket 20a will be pushed upward and drive the first slider 33a to move toward the push rod 42a to compress the first buffer 422a, so that the floating bracket 20a floats upward with the height of the obstacle 75a and achieves a buffering effect through the first buffer 422a.

[0210] After passing the roadblock 75a, the first slider 33a is pushed back to the working position P1a by the first buffer 422a. In this process, the second buffer 423a can provide a reverse elastic force, so that the first slider 33a is buffered accordingly, and is pressed against the working position P1a by the first buffer 422a and the second buffer 423a, so that the floating bracket 20a is lowered, driving the cleaning assembly 70a to contact the ground. In other words, through the bidirectional buffering setting of the first buffer 422a and the second buffer 423a, when the cleaning assembly 70a encounters the roadblock 75a, it can automatically float up and down in a bidirectional manner to adapt to the height change of the road surface without being pushed by the push rod 42a, thereby avoiding hard impact caused by the height change.

[0211] like Fig.31 As shown, a cleaning robot 1a is provided in another embodiment of the present disclosure, which differs from the above-mentioned embodiment in that the power source 41a of the above-mentioned embodiment drives the linkage component 30a to work in a horizontal direction, while the power source 41a of this embodiment drives the linkage component 30a to work by pushing the push rod 42a in a vertical direction.

[0212] In this embodiment, the cleaning robot 1a includes a main body 100a and a lifting mechanism 200a. The lifting mechanism 200a includes a fixed seat 10a, a floating bracket 20a, a linkage assembly 30a and a driving assembly 40a. The linkage assembly 30a includes a first connecting rod 31a and a second connecting rod 32a. The first connecting rod 31a includes a relative active end 311a and a driven end 312a. The active end 311a is movably arranged on the fixed seat 10a, and the driven end 312a is pivoted to the floating bracket 20a, and one end of the second connecting rod 32a is connected to the fixed seat 10a, and the other end is provided with a rotating shaft portion 323a, and is pivoted between the active end 311a and the driven end 312a. The fixed seat 10a also includes a first sliding groove 11a arranged along the vertical axis and a first slide rail 12a arranged in the first sliding groove 11a, and the linkage assembly 30a is correspondingly provided with a first slider 33a. The first sliding block 33a is pivotally disposed at the active end 311a and is movably disposed on the first sliding rail 12a.

[0213] The driving assembly 40a is correspondingly arranged above the first sliding groove 11a, and includes a power source 41a and a push rod 42a. The two opposite ends of the push rod 42a are respectively connected to the power source 41a and the first sliding block 33a. Therefore, when the push rod 42a is extended, it pushes the active end 311a to move downward, so that the first connecting rod 31a rotates through the rotating shaft portion 323a and swings relative to the second connecting rod 32a. At this time, the driven end 312a moves upward synchronously, driving the floating bracket 20a to rise and move toward the fixed seat 10a. When the push rod 42a is retracted, it pulls the active end 311a to move upward, driving the driven end 312a to move downward synchronously, causing the floating bracket 20a to descend, so as to drive the cleaning assembly to contact the ground.

[0214] The technical solutions in the embodiments of the present disclosure are described in detail below in conjunction with specific application scenarios.

[0215] Application scenario 1. Lifting and lowering driven by a push rod. When the power source 41a drives the push rod 42a to extend, the limit shaft 421a can be pushed to move relative to the first slider 33a, and the first buffer 422a pushes the first slider 33a to the working position P1a. At this time, the linkage assembly 30a drives the floating bracket 20a to descend, so that the cleaning assembly 70a contacts the ground and cleans.

[0216] Application scenario 2. When the first slider 33a is located at the working position P1a, and the cleaning component 70a contacts the ground, if the push rod 42a continues to extend, the first slider 33a will push and compress the first buffer 422a, and move toward the push rod 42a, so that the floating bracket 20a will not continue to descend, and the cleaning component 70a can be prevented from excessively squeezing the ground and causing damage to the lifting mechanism 200a.

[0217] Application scenario three. When the first slider 33a is pushed to the working position P1a and the cleaning assembly 70a contacts the ground, if it encounters a roadblock 75a, the floating bracket 20a can float up and down autonomously to adapt to the height change through the action of the first buffer 422a and the second buffer 423a, and after passing the roadblock 75a, it automatically returns to the working position P1a through the action of the first buffer 422a and the second buffer 423a.

[0218] To summarize, the disclosed embodiment provides a linkage action between the first slider and the floating bracket through the intersecting first connecting rod and the second connecting rod in the linkage assembly, and under the drive of the driving assembly and the buffering of the elastic force of the first buffer member, the cleaning robot can achieve stable lifting and lowering of the cleaning assembly, thereby controlling the distance and contact force between the cleaning assembly and the ground, and is suitable for different types of ground cleaning tasks, and has the advantages and functions of small shaking, no jamming, high transmission accuracy and two-way floating adaptability, thereby improving the cleaning quality and efficiency of the cleaning robot.

[0219] The disclosed embodiments further provide a cleaning device, which may be a sweeping robot, a mopping robot, a sweeping and mopping robot, or the like, which is used to clean work surfaces such as the floor.

[0220] like Fig.32 As shown, the cleaning device of the present disclosure includes a fan assembly 1b and an air outlet channel 2b. The fan assembly 1b can be installed on the body of the cleaning device. During operation, the fan assembly 1b inhales air from the air inlet 13b and discharges the air from the air outlet 14b to the air outlet channel 2b to generate negative pressure on the working surface, thereby sucking the garbage or dirt on the working surface into the sewage bucket on the body of the cleaning device. Specifically, the fan assembly 1b may include a motor 11b and a hood 12b. The motor 11b is arranged inside the hood 12b, and the air outlet 14b is arranged on the hood 12b.

[0221] like Fig.33 and Fig.34 As shown, specifically, in order to minimize the connection between the inlet end of the air outlet channel 2b of the present invention and the exhaust port 14b of the fan assembly 1b; the air outlet channel 2b includes a first channel 21b, and the first channel 21b includes at least two air outlet cavities 211b arranged in an axially stacked manner, each air outlet cavity 211b has an air outlet 212b, and two adjacent air outlet cavities 211b are constructed to be connected through the air outlet 212b; and the orthographic projections of the air outlets 212b of two adjacent air outlet cavities 211b on the cross-section of the first channel 21b are constructed to be arranged at an angle.

[0222] Thus, during the operation of the cleaning device of the present disclosure, after the airflow discharged from the fan assembly 1b enters the first channel 21b of the air outlet channel 2b, it will flow through each air outlet chamber 211b stacked along the axial direction in sequence. Since each air outlet chamber 211b has an air outlet 212b, two adjacent air outlet chambers 211b are connected through the air outlet 212b, and the positive projections of the air outlets 212b of the two adjacent air outlet chambers 211b on the cross section of the first channel 21b are arranged at an angle, so that when the airflow flows from the air outlet 212b of the first-level air outlet chamber 211b to the air outlet 212b of the next-level air outlet chamber 211b, it needs to move a certain distance along the next-level air outlet chamber 211b, and cannot flow directly to the air outlet 212b of the next-level air outlet chamber 211b. The air outlet channel 2b of the present disclosure can effectively extend the flow path of the airflow, thereby effectively reducing the flow speed of the airflow, and further effectively reducing the noise generated when the airflow flows in the first channel 21b. In particular, by reducing the flow velocity of the airflow, the high-frequency noise generated by the airflow during its flow can be effectively reduced, thereby effectively improving the user experience.

[0223] After actual machine testing, compared with the existing air outlet channel 2b, the air outlet channel 2b disclosed in the present invention can reduce the noise generated by the cleaning equipment when it is working by 2 to 5 decibels, while greatly reducing the proportion of high-frequency noise in the noise, effectively improving the user experience.

[0224] like Fig.35 and Fig.36 As shown, in one embodiment of the present disclosure, each air outlet chamber 211b is constructed in an annular shape. Since each air outlet chamber 211b is constructed in an annular shape, the airflow flows from the air outlet 212b of the first-stage air outlet chamber 211b to the air outlet 212b of the next-stage air outlet chamber 211b, and can be split into two parts in the annular next-stage air outlet chamber 211b, and flow to the next-stage air outlet 212b of the next-stage air outlet chamber 211b respectively. In the case where three or more air outlet chambers 211b are provided in the first channel 21b, the flow of the airflow from the second-stage air outlet chamber 211b to the final-stage air outlet chamber 211b is similar, and will not be repeated here. Dividing the airflow in the annular air outlet chamber 211b can effectively reduce the noise generated when the airflow impacts the cavity wall of the air outlet chamber 211b, thereby further reducing the noise generated by the cleaning device of the present disclosure when it is working.

[0225] To form the first channel 21b, Fig.34 and Fig.35As shown, in one embodiment of the present disclosure, the air outlet channel 2b includes an outer peripheral wall 23b that encloses a hollow inner cavity, and an inner peripheral wall 24b disposed in the hollow inner cavity of the outer peripheral wall 23b, and the outer peripheral wall 23b and the inner peripheral wall 24b enclose an annular channel; at least one partition 25b is distributed in the axial direction of the annular channel, and the partition 25b is configured to separate the annular channel into at least two air outlet chambers 211b. In the air outlet channel 2b of the present disclosure, an annular channel is enclosed by the outer peripheral wall 23b and the inner peripheral wall 24b, and at least one partition 25b is distributed in the axial direction of the annular channel, and the partition 25b can separate the annular channel into at least two air outlet chambers 211b, so that the processing difficulty of the first channel 21b can be effectively reduced, and it is also convenient to form an annular air outlet chamber 211b.

[0226] like Fig.35 and Fig.36 As shown, in one embodiment of the present disclosure, adjacent air outlet cavities 211b are constructed to be connected through two air outlets 212b, and the two air outlets 212b are symmetrically arranged about the center of the air outlet cavity 211b. Since adjacent air outlet cavities 211b are constructed to be connected through two air outlets 212b, the airflow in each air outlet cavity 211b can flow to the next-level air outlet cavity 211b through the two air outlets 212b, which can effectively divert the airflow and reduce the impact of the airflow on the cavity wall of the air outlet cavity 211b during the flow of the airflow, thereby reducing the noise generated by the airflow during the flow process, and will not cause a large degree of obstruction to the flow of the airflow, and the performance of the fan assembly 1b will not be lost too much. Moreover, the two air outlets 212b are symmetrically arranged about the center of the air outlet cavity 211b, so that the airflow flowing through the two air outlets 212b is consistent, and there will be no situation where the airflow of one air outlet 212b is too large and the airflow of the other air outlet 212b is too small, thereby achieving uniform diversion of the airflow.

[0227] Further, such as Fig.35 As shown, in one embodiment of the present disclosure, the orthographic projections of the air outlets 212b of two adjacent air outlet cavities 211b on the cross section of the first channel 21b are constructed to be at an angle of 90°. Since the orthographic projections of the air outlets 212b of two adjacent air outlet cavities 211b on the cross section of the first channel 21b are at an angle of 90°, the path lengths of the airflow flowing through the two air outlets 212b of each air outlet cavity 211b when passing through the air outlet 212b of the next-level air outlet cavity 211b are equal, and are both one-fourth of the circumference of the air outlet cavity 211b, so that it can further ensure that the airflow can be evenly distributed when moving in the air outlet cavity 211b.

[0228] like Fig.33 and Fig.34As shown, in one embodiment of the present disclosure, the air outlet channel 2b further includes a second channel 22b surrounded by an inner peripheral wall 24b, and the air flowing out of the air outlet 14b is configured to flow partially into the first channel 21b and partially into the second channel 22b. In this way, during the operation of the cleaning device of the present disclosure, after the airflow of the fan assembly 1b is discharged from the air outlet 14b, it partially flows into the first channel 21b and partially flows into the second channel 22b, which can effectively reduce the impact of the airflow on the pipe wall of the air outlet channel 2b during the flow process, thereby reducing the noise generated by the airflow during the flow process.

[0229] Further, such as Fig.33 and Fig.34 As shown, in one embodiment of the present disclosure, the air outlet 212b of the final air outlet chamber 211b in the first channel 21b is constructed to penetrate the side wall of the inner peripheral wall 24b in the radial direction, and the airflow in the final air outlet chamber 211b is constructed to flow radially into the end of the second channel 22b through its air outlet 212b, and merge with the airflow in the second channel 22b to be discharged. In this way, during the operation of the cleaning device of the present disclosure, the airflow flowing into the second channel 22b will continue to move along the axial direction of the air outlet channel 2b, and the airflow in the final air outlet chamber 211b will flow radially into the end of the second channel 22b through its air outlet 212b, so that the two airflows will collide and merge at the end of the second channel 22b, thereby effectively reducing the flow speed of the airflow to reduce the noise generated by the airflow.

[0230] Among them, Fig.33 and Fig.34 As shown, in one embodiment of the present disclosure, at least one blocking rib 221b is axially distributed on the inner wall of the second channel 22b, and the blocking rib 221b is constructed to extend radially from the inner wall of the second channel 22b toward the inlet end and form a buffer groove 222b between the inner wall of the second channel 22b. Since at least one blocking rib 221b is axially distributed on the inner wall of the second channel 22b, the blocking rib 221b extends obliquely from the inner wall of the second channel 22b radially toward the inlet end, and a buffer groove 222b is formed between the blocking rib 221b and the inner wall of the second channel 22b, when the airflow flows into the second channel 22b and encounters the blocking rib 221b, diversion will occur, part of the airflow will continue to flow downward from the blocking rib, and part of the airflow will flow along the blocking rib 221b to the buffer groove 222b. When the airflow collides with the inner wall of the second channel 22b, it will flow back and then collide and merge with the airflow flowing into the second channel 22b, thereby effectively reducing the flow speed of the airflow to reduce the noise generated by the airflow.

[0231] The number of the blocking ribs 221b can be set as required, such as Fig.33 and Fig.34As shown, in one embodiment of the present disclosure, two flow-blocking ribs 221b are distributed axially on the inner wall of the second channel 22b, so that a good balance can be maintained between reducing the noise generated by the fan assembly 1b and ensuring the fan performance, without losing too much fan performance, and effectively reducing the noise generated by the fan assembly 1b.

[0232] Further, such as Fig.34 As shown, in one embodiment of the present disclosure, the baffle rib 221b is constructed to be distributed on the inner wall of the second channel 22b in the circumferential direction, and the free end of the baffle rib 221b is constructed to enclose an opening for air flow to flow through; an axial flange extending axially toward the inlet end is provided at the free end of the baffle rib 221b. Since the blocking ribs 221b are distributed on the inner wall of the second channel 22b in the circumferential direction, and the free ends of the blocking ribs 221b are constructed to form an opening for airflow to flow through; an axial flange extending axially toward the inlet end is provided at the free end of the blocking ribs 221b, when the airflow flows into the second channel 22b and encounters the blocking ribs 221b, diversion will occur, part of the airflow will continue to flow downward from the central opening of the blocking ribs, and part of the airflow will flow along the blocking ribs 221b to the buffer grooves 222b around them. When the airflow collides with the inner wall of the second channel 22b, it will change its flow direction and flow back to the center of the second channel 22b, and then collide and merge with the airflow in the center of the second channel 22b, thereby further effectively reducing the flow velocity of the airflow to reduce the noise generated by the airflow.

[0233] like Fig.34 As shown, in one embodiment of the present disclosure, the inner circumferential wall 24b is constructed to be parallel to the outer circumferential wall 23b, one end of the inner circumferential wall 24b is constructed to be a conical portion 241b that gradually extends in a radial direction toward the inlet end, and the inlet of the second channel 22b surrounded by the conical portion 241b is constructed to correspond to the opening surrounded by the flow-blocking ribs 221b. Since one end of the inner circumferential wall 24b is gradually inclined and extended toward the inlet end in the radial direction, the inlet of the second channel 22b surrounded by the circumferential portion 241b corresponds to the opening surrounded by the flow-blocking ribs 221b. When the airflow flows into the air outlet channel 2b, the circumferential portion 241b on the inner circumferential wall 24b can divert the airflow. The airflow facing the inlet of the second channel 22b can directly flow into the second channel 22b, and the airflow not facing the second channel 22b can smoothly flow into the first channel 21b along the circumferential portion 241b. In this way, the airflow can be diverted to the first channel 21b and the second channel 22b without causing a large degree of obstruction to the flow of the airflow during the diversion process, thereby effectively ensuring the dirt suction performance of the cleaning equipment disclosed in the present invention.

[0234] like Fig.32 and Fig.33As shown, in one embodiment of the present disclosure, the inlet end of the air outlet channel 2b is connected to the exhaust port 14b through the transition channel 26b, the transition channel 26b is constructed to be in a funnel shape pointing to the outlet end, and the second channel 22b is constructed to be coaxially arranged with the transition channel 26b, and the edge of the second channel 22b and the edge of the transition channel 26b surround the inlet of the first channel 21b. In this way, during the operation of the cleaning device of the present disclosure, when the airflow generated by the fan assembly 1b flows out from the exhaust port, it will flow into the funnel-shaped transition channel 26b and gather and then flow out from the outlet of the transition channel 26b. The airflow located at the center part of the outlet of the transition channel 26b will directly flow into the second channel 22b, and the airflow located at the edge part of the outlet of the transition channel 26b will flow into the first channel 21b, thereby ensuring the reasonable diversion of the airflow.

[0235] like Fig.32 As shown, in one embodiment of the present disclosure, the inlet area of ​​the air inlet 13b is recorded as S1b, the inlet area of ​​the first channel 21b is recorded as S2b, the inlet area of ​​the second channel 22b is recorded as S3b, and the outlet area of ​​the air outlet channel 2b is recorded as S4b, and the following relationship is satisfied: S4b≥2bS1b, S1b=S3b, S2b≥2bS3b. According to actual machine tests, when the above quantitative relationship is satisfied, the air flow diversion ratio between the first channel 21b and the second channel 22b of the cleaning device of the present disclosure is relatively appropriate when working, the noise volume generated by the cleaning device is relatively small, and the performance loss of the fan component 1b is relatively small, and the dirt suction effect is relatively good.

[0236] The present disclosure provides a cleaning device, which includes a fan assembly 1b and an air outlet channel 2b, wherein the inlet end of the air outlet channel 2b is connected to the exhaust port 14b of the fan assembly 1b; the air outlet channel 2b includes an outer peripheral wall 23b that forms a hollow inner cavity, and an inner peripheral wall 24b that is arranged in the hollow inner cavity of the outer peripheral wall 23b, the outer peripheral wall 23b and the inner peripheral wall 24b form a first channel 21b, and the inner peripheral wall 24b forms a second channel 22b, and the air flowing out of the exhaust port 14b is constructed to partially flow into the first channel 21b and partially flow into the second channel 22b.

[0237] In this way, during the operation of the cleaning device disclosed in the present invention, after the airflow of the fan assembly 1b is discharged from the exhaust port 14b, part of it flows into the first channel 21b surrounded by the outer peripheral wall 23b and the inner peripheral wall 24b, and part of it flows into the second channel 22b surrounded by the inner peripheral wall 24b, which can effectively reduce the impact of the airflow on the pipe wall of the air outlet channel 2b during the flow process, thereby reducing the noise generated by the airflow during the flow process.

[0238] The present disclosure also provides an air outlet channel 2b, the inlet end of the air outlet channel 2b is configured to be connected to the exhaust port 14b of the fan assembly 1b; the air outlet channel 2b includes a first channel 21b, the first channel 21b includes at least two air outlet cavities 211b arranged in an axially stacked manner, each air outlet cavity 211b has an air outlet 212b, and two adjacent air outlet cavities 211b are configured to be connected through the air outlet 212b; and the orthographic projections of the air outlets 212b of two adjacent air outlet cavities 211b on the cross-section of the first channel 21b are configured to be arranged at an angle; the airflow entering the first channel 21b from the exhaust port 14b is configured to be discharged after passing through the air outlet cavities 211b in sequence.

[0239] In one embodiment of the present disclosure, the air outlet channel 2b includes an outer peripheral wall 23b forming a hollow inner cavity, and an inner peripheral wall 24b arranged in the hollow inner cavity of the outer peripheral wall 23b, and the outer peripheral wall 23b and the inner peripheral wall 24b form an annular channel; at least one partition 25b is distributed in the axial direction of the annular channel, and the partition 25b is configured to divide the annular channel into at least two air outlet cavities 211b; the air outlet channel 2b also includes a second channel 22b surrounded by the inner peripheral wall 24b, and the air flowing out of the exhaust port 14b is configured to flow partially into the first channel 21b and partially into the second channel 22b. In this way, during the use of the air outlet channel 2b of the present invention, after the airflow of the fan assembly 1b is discharged from the exhaust port 14b, part of it flows into the first channel 21b surrounded by the outer peripheral wall 23b and the inner peripheral wall 24b, and part of it flows into the second channel 22b surrounded by the inner peripheral wall 24b, which can effectively reduce the impact of the airflow on the pipe wall of the air outlet channel 2b during the flow process, thereby reducing the noise generated by the airflow during the flow process.

[0240] Application Scenario

[0241] The present disclosure provides a cleaning device, which can be a cleaning device such as a sweeping robot, a mopping robot, a sweeping and mopping robot, etc., for cleaning working surfaces such as the ground. The cleaning device of the present disclosure includes a fan assembly 1b and an air outlet channel 2b, and the fan assembly 1b can be installed on the body of the cleaning device. During operation, the fan assembly 1b inhales airflow from the air inlet 13b and discharges the airflow from the air outlet channel 2b to generate negative pressure on the working surface, thereby sucking garbage or dirt on the working surface into a sewage bucket on the body of the cleaning device.

[0242] Specifically, in order to minimize the connection between the inlet end of the air outlet channel 2b of the present invention and the exhaust port 14b of the fan assembly 1b; the air outlet channel 2b includes a first channel 21b, and the first channel 21b includes at least two air outlet cavities 211b arranged in an axially stacked manner, each air outlet cavity 211b has an air outlet 212b, and two adjacent air outlet cavities 211b are constructed to be connected through the air outlet 212b; and the orthographic projections of the air outlets 212b of the two adjacent air outlet cavities 211b on the cross-section of the first channel 21b are constructed to be arranged at an angle.

[0243] Thus, during the operation of the cleaning device of the present disclosure, after the airflow discharged from the fan assembly 1b enters the first channel 21b of the air outlet channel 2b, it will flow through each air outlet chamber 211b stacked along the axial direction in sequence. Since each air outlet chamber 211b has an air outlet 212b, two adjacent air outlet chambers 211b are connected through the air outlet 212b, and the positive projections of the air outlets 212b of the two adjacent air outlet chambers 211b on the cross section of the first channel 21b are all arranged at an angle, so that when the airflow flows from the air outlet 212b of the first-level air outlet chamber 211b to the air outlet 212b of the next-level air outlet chamber 211b, it needs to move a certain distance along the next-level air outlet chamber 211b, and cannot flow directly to the air outlet 212b of the next-level air outlet chamber 211b. The air outlet channel 2b of the present disclosure can effectively extend the flow path of the airflow, thereby effectively reducing the flow speed of the airflow, and further effectively reducing the noise generated when the airflow flows in the first channel 21b. In particular, by reducing the flow velocity of the airflow, the high-frequency noise generated by the airflow during its flow can be effectively reduced, thereby effectively improving the user experience.

[0244] After actual machine testing, compared with the existing air outlet channel 2b, the air outlet channel 2b disclosed in the present invention can reduce the noise generated by the cleaning equipment when it is working by 2 to 5 decibels, while greatly reducing the proportion of high-frequency noise in the noise, effectively improving the user experience.

[0245] The present disclosure also provides a cleaning device, which can be a handheld cleaning device, such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld floor scrubber, and other handheld cleaning devices known to those skilled in the art. It can also be a sweeping robot, a mopping robot, a sweeping and mopping robot, and other self-propelled cleaning devices used to clean work surfaces such as floors, sofas, and carpets. Fig.37 In the embodiment of the cleaning device of the present disclosure as a commercial floor scrubber robot, the roller brush assembly 2c of the floor scrubber may need to perform cleaning work on various work surfaces in commercial scenarios, such as wooden floors, stone tiles, ceramic floors, short-hair carpets, long-hair carpets, etc. On different work surfaces, the appropriate force required for the roller brush assembly 2c of the floor scrubber to perform cleaning is different.

[0246] refer to Fig.37 and Fig.38 The cleaning device comprises: a body 1c, a roller brush assembly 2c and a first lifting assembly 3c, wherein the roller brush assembly 2c is configured to clean a working surface. The roller brush assembly 2c is hinged to the body 1c through a bracket 11c, specifically, the roller brush assembly 2c is hinged below the body 1c, so as to clean the working surface. Fig.38 As shown, the roller brush assembly 2c also includes a driving motor 24c, and the roller brush can rotate under the action of the driving motor 24c. In addition, the roller brush assembly 2c is also configured to move toward or away from the working surface relative to the machine body 1c. In a scenario where the working surface is a horizontal surface, the roller brush assembly 2c can rise or fall in the vertical direction, thereby adjusting the interference between the roller brush assembly 2c and the working surface. Specifically, the roller brush assembly 2c can be moved vertically by the first lifting assembly 3c.

[0247] refer to Fig.39 The first lifting assembly 3c includes an input mechanism and an output mechanism disposed on the machine body 1c, and the roller brush assembly 2c is configured to be in transmission connection with the output mechanism so as to move in a direction away from the working surface under the drive of the output mechanism. Fig.39 As shown, the first lifting assembly 3c can be arranged on one side of the roller brush assembly 2c, wherein the input mechanism includes an input shaft 35c, and the output mechanism includes an output shaft 36c, wherein the output shaft 36c is transmission-connected to the roller brush assembly 2c through a coupling 221c. Specifically, a connecting compression spring 361c can be arranged between the output shaft 36c and the coupling 221c, and the connecting compression spring 361c can continuously provide a force for the coupling 221c toward the roller brush assembly 2c, thereby maintaining the connection relationship.

[0248] In one embodiment of the present disclosure, the roller brush assembly 2c includes a connecting frame 21c and a transmission rod 22c. The transmission rod 22c is connected to the output shaft 36c through a coupling 221c. When the output shaft 36c rotates, the transmission rod 22c can rotate synchronously with the output shaft 36c. Two connecting frames 21c can be provided, and the two connecting frames 21c are respectively fixedly connected to the positions on both sides of the top of the roller brush assembly 2c. Fig.39As shown, the two connecting frames 21c may be provided with a lifting portion 211c, and the lifting portion 211c is a protruding structure extending horizontally, and the two lifting portions 211c are respectively matched with two lifting levers 23c. Among them, one end of the lifting lever 23c is fixedly connected to the transmission rod 22c, and the other end is abutted and matched with the lifting portion 211c. The two lifting levers 23c are respectively arranged at positions on both sides of the transmission rod 22c, that is, at positions corresponding to the two lifting portions 211c. When the transmission rod 22c rotates, the two lifting levers 23c rotate with the transmission rod 22c with the transmission rod 22c as the axis, and drive the roller brush assembly 2c to move vertically through the lifting portion 211c.

[0249] The input mechanism is constructed to be able to move to a coupled state in which it is transmission-connected with the output mechanism to drive the output mechanism to move, and to be able to move to a decoupled state in which it is disconnected from the output mechanism; in the decoupled state, the roller brush assembly 2c is constructed to move toward the working surface under the action of gravity until it is in contact with the working surface.

[0250] Specifically, when in the coupled state, the input mechanism is connected to the output mechanism, and the output shaft 36c can rotate clockwise under the driving action of the input shaft 35c. The transmission rod 22c rotates clockwise along with the output shaft 36c through the coupling 221c, thereby driving the lifting lever 23c to rotate clockwise with the transmission rod 22c as the axis, so that the roller brush assembly 2c moves away from the working surface. It should be noted that the "clockwise" mentioned above is a reference to Fig.39 The direction of view of the output shaft 36c and the driving rod 22c is determined by whether the rotation direction is clockwise or counterclockwise, which depends on the position between the observer and the cleaning device. In the subsequent description, the above process is defined as the output shaft 36c "positive rotation".

[0251] When in the decoupled position, the roller brush assembly 2c falls to the lowest position under the action of gravity. At this time, the lifting portion 211c presses down the lifting lever 23c, so that the lifting lever 23c rotates counterclockwise with the transmission rod 22c as the axis. The transmission rod 22c rotates counterclockwise under the driving action of the lifting lever 23c, and the output shaft 36c rotates counterclockwise with the transmission rod 22c through the coupling 221c. In the subsequent description, the above process is defined as the "reversal" of the output shaft 36c.

[0252] It should be noted that the input shaft 35c in the present disclosure is controlled and rotated by a motor and is constructed to be able to rotate in one direction only and cannot rotate in the opposite direction. If the input mechanism is not decoupled from the output mechanism when the output shaft 36c is reversed, the reverse rotation of the output shaft 36c will also drive the input shaft 35c to reverse, which will cause damage to the motor that controls the rotation of the input shaft 35c. Therefore, when the transmission rod 22c is in a scenario where it needs to be reversed, the input mechanism needs to run to a decoupled state where it is disconnected from the output mechanism.

[0253] In one embodiment of the present disclosure, the cleaning device further includes a control unit, which is configured to control the first lifting assembly 3c to adjust the relative height between the roller brush assembly 2c and the working surface based on the rotational resistance between the roller brush assembly 2c and the working surface. In a specific application scenario, when the cleaning device moves from a hard floor to a carpet, the working surface of the roller brush assembly 2c changes from a hard floor to a carpet, the friction coefficient of the working surface increases significantly, and the rotational resistance between the roller brush assembly 2c and the working surface increases significantly. If the same cleaning force is maintained, it will cause damage to the carpet, accelerate the wear of the roller brush assembly 2c, and cause the drive motor 24c of the roller brush assembly to overload. The control component can detect the increase in the rotational resistance between the roller brush assembly 2c and the working surface, and control the first lifting assembly 3c to lift the roller brush assembly 2c until it is lifted to a height with appropriate resistance.

[0254] In a specific embodiment of the present disclosure, the roller brush assembly 2c includes a drive motor 24c, and the control unit is configured to, in response to the current of the drive motor 24c being greater than a threshold value, control the input mechanism to move to a coupled state with the output mechanism and drive the roller brush assembly 2c to lift upward; and in response to the current of the drive motor 24c being less than a threshold value, control the input mechanism to move to a decoupled state with the output mechanism, so that the roller brush assembly 2c moves toward the working surface under the action of gravity until it is in contact with the working surface.

[0255] The control unit has a preset current threshold of the driving motor 24c, which can be an interval range. When the current of the driving motor 24c is within the threshold range, it means that the interference between the roller brush assembly 2c and the working surface is appropriate, that is, it can be cleaned without excessively wearing the working surface and the roller brush assembly 2c.

[0256] When the control unit detects that the current of the drive motor 24c is greater than the threshold value, it means that the friction between the roller brush assembly 2c and the working surface is too large and the interference is too large, and the roller brush assembly 2c needs to be lifted. At this time, it is necessary to control the input mechanism to move to a coupled state with the output mechanism transmission, so as to control the lifting of the roller brush assembly 2c by rotating the input shaft 35c. During the lifting process, the control unit can detect the current of the drive motor 24c in real time. When the current is reduced to within the threshold range, the input shaft 35c can be controlled to stop rotating, so that the roller brush assembly 2c maintains the appropriate position height. It should be noted that after the input shaft 35c stops rotating, the input mechanism remains in the coupled state. If the control unit detects that the current is greater than the threshold again, the roller brush assembly 2c can continue to be lifted.

[0257] When the control unit detects that the current of the drive motor 24c is less than the threshold value, it means that the friction between the roller brush assembly 2c and the working surface is too small and the interference is too small, and the roller brush assembly 2c needs to be lowered. At this time, it is necessary to control the input mechanism to move to a decoupled state from the output mechanism so that the roller brush assembly 2c falls back to the lowest position in contact with the working surface under the action of gravity. After falling back, there is a high probability that the interference between the roller brush assembly 2c and the working surface will be too large, so the roller brush assembly 2c needs to be lifted again. The input mechanism needs to move to the coupled state again to control the roller brush assembly 2c to be lifted to a suitable position.

[0258] This embodiment uses the method of detecting the current of the driving motor to determine whether the interference between the roller brush assembly 2c and the working surface meets the requirements. In practical applications, the height position of the roller brush assembly 2c can also be determined by detecting one or some parameters of other components in the cleaning device. For example, a displacement sensor can be set on the cleaning device to directly obtain the position information of the roller brush assembly 2c. The present disclosure does not specifically limit the method of obtaining the height position of the roller brush assembly 2c, or the method of obtaining the friction between the roller brush assembly 2c and the working surface.

[0259] The present disclosure provides a first lifting assembly 3c so that the cleaning device can quickly adapt to different working surfaces, thereby meeting the use requirements of commercial scenarios. Specifically, the first lifting assembly 3c includes an input mechanism and an output mechanism, and the input mechanism can move to a coupled state and a decoupled state. In the coupled state, the output mechanism is connected to the input mechanism in a transmission manner to drive the roller brush assembly 2c to lift; in the decoupled state, the output mechanism is disconnected from the input mechanism in transmission, and the roller brush assembly 2c falls and resets.

[0260] When it is detected that the force of the roller brush assembly 2c in cleaning the working surface is too large, the first lifting assembly 3c runs to the coupling state to drive the roller brush assembly 2c to be lifted to a position with appropriate force, thereby avoiding damage to the working surface, avoiding excessive wear of the roller brush assembly 2c, and also avoiding overload operation of the drive motor 24c of the roller brush assembly 2c. When it is detected that the force of the roller brush assembly 2c in cleaning the working surface is too small, the first lifting assembly 3c runs to the decoupling state to make the roller brush assembly 2c fall back to the lowest position, and then runs to the coupling state again to drive the roller brush assembly 2c to be lifted to a position with appropriate force, so that the roller brush assembly 2c can fully clean the working surface.

[0261] The first lifting assembly 3c can drive the roller brush assembly 2c to lift or lower to a suitable position according to different conditions of the working surface, thereby quickly adapting to various working surfaces, effectively preventing damage to the working surface, extending the life of the roller brush assembly 2c and its drive motor 24c, and achieving comprehensive cleaning.

[0262] The specific structure of the first lifting component 3c will be introduced in detail below.

[0263] refer to Fig.39 and Fig.43 The first lifting assembly 3c includes a gear box 30c, and most of the components of the input mechanism and the output mechanism are arranged in the gear box, and only one end of the input shaft 35c and the output shaft 36c respectively passes through the housing of the gear box 30c and is exposed outside the gear box 30c. The input shaft 35c passes through one side of the gear box 30c to connect with the motor in the body 1c; the output shaft 36c passes through the other side of the gear box 30c to connect with the transmission rod 22c through the coupling 221c.

[0264] In one embodiment of the present disclosure, reference Fig.40 The input mechanism includes an input shaft 35c and a first gear 31c disposed on the input shaft 35c. The first gear 31c is coaxially disposed and fixedly connected with the input shaft 35c. When the input shaft 35c rotates, the first gear 31c can rotate synchronously. The output mechanism includes an output shaft 36c and a second gear 32c disposed on the output shaft 36c. The second gear 32c is coaxially disposed and fixedly connected with the output shaft 36c. When the output shaft 36c rotates, the second gear 32c can rotate accordingly. Similarly, when the second gear 32c rotates, the output shaft 36c will also rotate accordingly.

[0265] When the first lifting assembly 3c is in a coupled state, the first gear 31c and the second gear 32c are in transmission connection, so as to drive the output shaft 36c to rotate forward through the input shaft 35c; when it is in a decoupled state, the first gear 31c and the second gear 32c are out of transmission, and the output shaft 36c is reversed under the gravity of the roller brush assembly 2c. Fig.40 In the embodiment shown, the first gear 31c and the second gear 32c are not directly meshed and connected together, but the first gear 31c and the second gear 32c can achieve transmission through the transmission effect of other gears. In other embodiments, the first gear 31c can also be directly meshed and transmitted with the second gear 32c.

[0266] Further, refer to Figure 40 to Figure 42, a toothless portion 312c and a toothed portion 311c are provided on the first gear 31c along its circumference. It is understood that transmission can only be achieved when the toothed portion 311c of the first gear 31c rotates to mesh with other gears. When in the coupled state, the toothed portion 311c of the first gear 31c is configured to rotate and be transmission-connected with the second gear 32c to drive the second gear 32c to rotate. Specifically, when in the coupled state, the toothed portion 311c of the first gear 31c is meshed and connected with the third gear 33c, and is transmitted to the second gear 32c through the self-locking component 34c, so that the second gear 32c drives the output shaft 36c to rotate. The third gear 33c and the self-locking component 34c together constitute a transmission mechanism to achieve transmission between the first gear 31c and the second gear 32c. The specific structure and movement mode of the transmission mechanism will be described in detail later. The toothed portion 311c of the first gear 31c can also be directly meshed with the second gear 32c to achieve a coupled state.

[0267] The toothed portion 311c of the first gear 31c may be provided with a plurality of racks, and each rack may be correspondingly set as a "gear" for adjusting the height of the roller brush assembly 2c. When in the coupled state, each time a gear is rotated, that is, each time a tooth on the toothed portion 311c drives the second gear 32c to rotate a predetermined angle, the roller brush assembly 2c can be adjusted to a corresponding predetermined height. It should be noted that the above-mentioned "predetermined height" is actually a very small height, so that the adjustment accuracy of the first lifting assembly 3c can meet the use requirements. The specific number of racks on the toothed portion 311c can be adjusted according to the actual situation, so as to adjust the height range of the roller brush assembly 2c lifted by the first lifting assembly 3c.

[0268] When in the decoupled state, the toothless portion 312c of the first gear 31c is configured to rotate and cooperate with the second gear 32c to release the transmission with the second gear 32c. Specifically, the first gear 31c is driven by the input shaft 35c to rotate to a position where the toothless portion 312c cooperates with the third gear 33c. At this time, the toothed portion 311c is disengaged from the third gear 33c, and the input mechanism is disengaged from the transmission mechanism, thereby disengaging the input mechanism from the output mechanism, that is, disengaging from the second gear 32c. The toothless portion 312c of the first gear 31c can also directly cooperate with the second gear 32c to achieve the decoupled state.

[0269] In a specific embodiment of the present disclosure, continue to refer to Fig.40The first lifting assembly 3c also includes a second one-way locking member 313c, which is configured to mesh with the first gear 31c to allow the first gear 31c to rotate in the forward direction and lock it in the reverse direction. By providing the second one-way locking member 313c, the first gear 31c can be configured as a ratchet that can only rotate in one direction. The input shaft 35c, the first gear 31c and the entire input mechanism are configured to rotate only in one direction, that is, "forward rotation". This is also one of the reasons why the first lifting assembly 3c must be in a decoupled state when the output shaft 36c is reversed.

[0270] refer to Fig.45 The gear box 30c is provided with a second reset member 314c which cooperates with the second one-way locking member 313c. The second reset member 314c may be a compression spring. The second reset member 314c is pre-pressed between the inner wall of the gear box 30c and the end surface of one side of the second one-way locking member 313c, thereby providing the second one-way locking member 313c with an elastic force to continuously abut against the first gear 31c, so as to achieve reverse locking.

[0271] In the embodiment where the first gear 31c and the second gear 32c can be directly meshed together, the input shaft 35c drives the first gear 31c to rotate unidirectionally. When the toothed portion 311c is rotated to mesh with the second gear 32c, that is, it moves to the coupled state, the second gear 32c drives the output shaft 36c to rotate together, thereby driving the roller brush assembly 2c to rise. When the toothless portion 312c is rotated to cooperate with the second gear 32c, and moves to the decoupled state, the roller brush assembly 2c falls to drive the output shaft 36c and the second gear 32c to reverse. There is a problem with this embodiment. After the second gear 32c reverses, the position of each rack cannot be determined; when the roller brush assembly 2c needs to be lifted again, that is, when the toothed portion 311c of the first gear 31c needs to mesh with the second gear 32c again, it may cause the racks of the two to be unable to mesh and fight each other.

[0272] In order to solve the above problems, the first lifting component 3c of the present invention does not adopt the solution of direct meshing of the first gear 31c and the second gear 32c, but introduces a transmission mechanism. The specific structure of the transmission mechanism and the coordination method of the transmission mechanism with the input mechanism and the output mechanism will be introduced in detail below.

[0273] In one embodiment of the present disclosure, continue to refer to Figure 40 to Figure 43The first lifting assembly 3c also includes a transmission mechanism, which includes a third gear 33c that rotates freely relative to the output shaft 36c and a self-locking component 34c. The first gear 31c is configured to be able to rotate to a state where the toothed portion 311c is meshed with the third gear 33c, and a state where the toothless portion 312c corresponds to the third gear 33c during rotation. The self-locking component 34c is configured to be able to move to a state where it is meshed with the third gear 33c and the second gear 32c, and to be able to move to a state where it is disengaged from the third gear 33c and the second gear 32c.

[0274] like Fig.40 , Fig.43 As shown, the third gear 33c can be coaxially arranged with the output shaft 36c and can rotate freely relative to the output shaft 36c. The third gear 33c can have two parts that are concentrically arranged and have different diameters. The part with a larger diameter is configured to be meshed with the first gear 31c; the part with a smaller diameter can have the same diameter as the second gear, so that the self-locking component 34c can mesh with the third gear 33c and the second gear 32c at the same time, and transmit the rotation of the third gear 33c to the second gear 32c.

[0275] Further, such as Fig.41 As shown, the self-locking component 34c includes a self-locking bracket 342c and a fourth gear 341c that is rotatably connected to the self-locking bracket 342c and is configured to engage or disengage with the third gear 33c and the second gear 32c. The self-locking bracket 342c can drive the fourth gear 341c to move between the engaged position and the disengaged position. When moving to the engaged position, the fourth gear 341c is meshed and connected with the third gear 33c and the second gear 32c at the same time. When the first gear 31c rotates with the input shaft 35c, the third gear 33c meshed and connected with the first gear 31c rotates, and the fourth gear 341c transmits the rotation of the third gear 33c to the second gear 32c, thereby rotating the output shaft 36c. When moving to the disengaged position, the fourth gear 341c is disconnected from the third gear 33c and the second gear 32c at the same time. When the first gear 31c rotates with the input shaft 35c, the third gear 33c meshing with the first gear 31c rotates, and the fourth gear 341c cannot transmit the rotation of the third gear 33c to the second gear 32c, and the output shaft 36c no longer rotates.

[0276] This solves the problem in the embodiment where the first gear 31c and the second gear 32c are directly meshed, that is, when the roller brush assembly 2c needs to be lifted for a second time, the two gears may be difficult to mesh. Specifically, in this embodiment, a transmission mechanism is provided, and a third gear 33c and a self-locking component 34c are provided between the first gear 31c and the second gear 32c, wherein the self-locking component 34c can be controlled to move between the meshing position and the disengagement position, so that the fourth gear 341c can be transmitted or terminated. When the roller brush assembly 2c needs to be lifted for a second time, the rack position of the second gear 32c after the previous reversal is still uncertain; the third gear 33c is freely rotatable relative to the output shaft 36c, and its specific rack position is also uncertain; the fourth gear 341c needs to be meshed with the third gear 33c and the second gear 32c at the same time to achieve transmission, so when the fourth gear 341c moves to the meshing position again, it is very likely that it will not be directly meshed. However, the volume of the fourth gear 341c is much smaller than the second gear 32c and the third gear 33c, and the third gear 33c and the fourth gear 341c are both gears that can rotate freely. Therefore, when the gears clash, they can jump teeth adaptively to make the fourth gear 341c get into the meshing position.

[0277] In one embodiment of the present disclosure, reference Fig.41 and Fig.44 The input mechanism further includes a first cam plate 37c disposed on the input shaft 35c, and a first flange 371c is disposed on the first cam plate 37c. The first cam plate 37c is configured to rotate with the input shaft 35c so that the first flange 371c pushes the self-locking bracket 342c to move away from the third gear 33c and the second gear 32c, so that the fourth gear 341c is disengaged from the third gear 33c and the second gear 32c. The self-locking bracket 342c is configured to reset under the action of elastic force after the first flange 371c rotates to leave the self-locking bracket 342c to make the fourth gear 341c mesh with the third gear 33c and the second gear 32c.

[0278] Specifically, Fig.44 As shown, the first cam plate 37c is constructed in a water drop shape, wherein the sharper end is the first flange 371c. The first cam plate 37c is fixedly connected to the input shaft 35c, and when the input shaft 35c rotates, the first cam plate 37c can rotate with the input shaft 35c. During the rotation of the first cam plate 37c, the first flange 371c can squeeze the self-locking bracket 342c once, so that the fourth gear 341c moves to the disengaged position, and the output mechanism and the input mechanism are disengaged from the transmission.

[0279] In a specific embodiment of the present disclosure, reference Fig.45The gear box 30c is provided with a third reset member 343c which cooperates with the self-locking bracket 342c. The third reset member 343c may be a compression spring. The third reset member 343c is pre-pressed on the end of the self-locking bracket 342c away from the input shaft 35c to provide an elastic force that continuously abuts against the self-locking bracket 342c and makes the self-locking bracket 342c tend to move toward the input shaft 35c. Fig.41 As shown, when the first cam plate 37c rotates to the position where the first flange 371c squeezes the self-locking bracket 342c, the self-locking bracket 342c drives the fourth gear 341c to move from the engaged position to the disengaged position; when the first cam plate 37c continues to rotate to the position where the first flange 371c no longer squeezes the self-locking bracket 342c, the self-locking bracket 342c is reset to the engaged position under the elastic force of the third reset member 343c.

[0280] In one embodiment of the present disclosure, since the first gear 31c and the first cam plate 37c rotate coaxially and synchronously, the relative position relationship between the first gear 31c and the first cam plate 37c needs to be designed, and specifically, the matching relationship between the toothed portion 311c, the toothless portion 312c and the first flange 371c needs to be defined. The matching relationship between the toothed portion 311c, the toothless portion 312c and the first flange 371c of the first gear 31c is as follows:

[0281] Before the first flange 371c pushes the self-locking bracket 342c to move, the toothed portion 311c is constructed to mesh with the third gear 33c; after the first flange 371c pushes the self-locking bracket 342c to move into place, the toothless portion 312c rotates to a position corresponding to the third gear 33c. At the moment when the self-locking bracket 342c and the first flange 371c are squeezed, the first gear 31c is in a state of meshing with the third gear 33c through the toothed portion 311c. After the self-locking bracket 342c is completely pushed away, the second gear 32c and the third gear 33c are disengaged from the transmission. At this time, the first gear 31c can still be in a state of transmission connection with the second gear 32c, or it can have been rotated to a state of disengagement where the toothless portion 312c cooperates with the second gear 32c. When the first cam plate 37c continues to rotate until the first flange 371c no longer squeezes the self-locking bracket 342c, the self-locking bracket 342c is reset to the engaged state under the action of elastic force, and the first gear 31c rotates to a position where the toothless portion 312c cooperates with the third gear 33c, and the third gear 33c is disengaged from the first gear 31c, thereby keeping the output mechanism out of transmission from the input mechanism.

[0282] In one embodiment of the present disclosure, the second gear 32c is configured to be a gear that can only rotate in one direction in a coupled state and can reverse in a decoupled state. Figure 41 to Figure 42The first lifting assembly 3c further includes a first one-way locking member 321c, which is configured to mesh with the second gear 32c to allow the second gear 32c to rotate in a forward direction and to be locked in a reverse direction. Fig.41 The first one-way locking member 321c is meshed with the second gear 32c, so that the second gear 32c can only rotate in one direction and cannot be reversed. Fig.42 The first one-way locking member 321c is separated from the second gear 32c and no longer presses against the second gear 32c, so that the second gear 32c can be reversed under the gravity of the roller brush assembly 2c.

[0283] Further, refer to Fig.42 and Fig.44 The input mechanism also includes a second cam plate 38c arranged on the input shaft 35c, and a second flange 381c is arranged on the second cam plate 38c. The second flange 381c is constructed to rotate to push the first one-way locking member 321c to disengage from the second gear 32c, and after rotating to disengage from the first one-way locking member 321c, the first one-way locking member 321c is reset to engage with the second gear 32c under the action of elastic force.

[0284] Specifically, Fig.44 As shown, the second cam plate 38c is constructed in a water drop shape, wherein the sharper end is the second flange 381c. The second cam plate 38c is fixedly connected to the input shaft 35c, and when the input shaft 35c rotates, the second cam plate 38c can rotate with the input shaft 35c. During one rotation of the second cam plate 38c, the second flange 381c can squeeze the first one-way locking member 321c once to push the first one-way locking member 321c to disengage from the second gear 32c, and the second gear 32c is no longer one-way locked and can be reversed. The second cam plate 38c can be an integrally formed structure with the first cam plate 37c, or can be constructed as two separate independent structures, and the present disclosure does not limit this.

[0285] In a specific embodiment of the present disclosure, reference Fig.45 The gear box 30c is provided with a first reset member 322c which cooperates with the first one-way locking member 321c. The first reset member 322c may be a compression spring. The first reset member 322c is pre-pressed on the inner wall of the gear box 30c and one end face of the first one-way locking member 321c to provide an elastic force that continuously abuts against the first one-way locking member 321c and makes the first one-way locking member 321c tend to abut against the second gear 32c. Fig.42As shown, when the second cam plate 38c rotates to the position where the second flange 381c squeezes the first one-way locking member 321c, the first one-way locking member 321c disengages from the second gear 32c; when the second cam plate 38c continues to rotate to the position where the second flange 381c no longer squeezes the first one-way locking member 321c, the first one-way locking member 321c is reset to the position meshing with the second gear 32c under the action of the elastic force of the first reset member 322c, so as to one-way lock the second gear 32c again.

[0286] In one embodiment of the present disclosure, Fig.44 As shown, since the first cam plate 37c and the second cam plate 38c of the present disclosure are integrally formed and coaxially rotated, it is necessary to design the relative position relationship between the first cam plate 37c and the second cam plate 38c. Specifically, it is necessary to define the matching relationship between the first flange 371c and the second flange 381c. The matching relationship between the second flange 381c and the first flange 371c is as follows:

[0287] After the first flange 371c pushes the self-locking bracket 342c to move into place, the second flange 381c pushes the first one-way locking member 321c to disengage from the second gear 32c. The moment when the second flange 381c pushes the first one-way locking member 321c to disengage from the second gear 32c is the moment when the roller brush assembly 2c can fall to the lowest position under the action of gravity. At this time, the output shaft 36c drives the second gear 32c to reverse together. Since it is necessary to prevent the first gear 31c and the input shaft 35c from being damaged by the reverse rotation, the input mechanism and the output mechanism must be decoupled before the second gear 32c reverses. In other words, before the reverse rotation occurs, the first flange 371c needs to push the self-locking bracket 342c until the fourth gear 341c is disengaged from the second gear 32c and the third gear 33c. If the self-locking bracket 342c is pushed and reset to the meshing position under the elastic force of the third reset member 343c before the reversal occurs, it is necessary to ensure that the first gear 31c has rotated to the position where the toothless portion 312c cooperates with the third gear 33c.

[0288] The present disclosure is provided with a total of three decoupling structures: the first is the structure of the first gear 31c, by providing a toothed portion 311c and a toothless portion 312c, the toothed portion 311c can perform the first transmission with the third gear 33c, and when the toothless portion 312c rotates to cooperate with the third gear 33c, the transmission cannot be performed; the second structure is the self-locking component 34c, the fourth gear 341c can perform the second transmission between the third gear 33c and the second gear 32c, and when the self-locking bracket 342c is squeezed by the first flange 371c, the transmission cannot be performed; the third structure is the first one-way locking member 321c, when the first one-way locking member 321c is in a locked state, the second gear 32c can only rotate in one direction, and the roller brush assembly 2c cannot fall, and when the second flange 381c squeezes the first one-way locking member 321c to a state of disengagement from the second gear 32c, reversal can occur.

[0289] It can be seen that the first two structures are decoupled from the transmission relationship. If the transmission is disengaged at any position, the input mechanism and the output mechanism can be disengaged from the transmission; and the third structure is the final "switch". Only when the transmission is disengaged can the first one-way locking member 321c be disengaged from the second gear 32c. Only then does it truly enter the decoupling state, and the roller brush assembly 2c falls and resets to enter the next lifting cycle.

[0290] If only the first structure and the third structure are set, that is, the first gear 31c is directly meshed and connected to the second gear 32c, the "rack fighting" problem mentioned above will occur, resulting in the inability of the toothed portion 311c of the first gear 31c to mesh with the second gear 32c again after the reversal. If only the second structure and the third structure are set, since the self-locking component 34c is reset by the elastic force of the third reset member 343c, the time required for resetting may deviate from the theoretical data. Therefore, the self-locking component 34c may be reset during the reversal of the output shaft or even before the reversal occurs. This will cause the decoupling to fail, causing the input shaft 35c to follow the reversal. Therefore, in actual application, the three decoupling mechanisms are indispensable, and the toothless portion 312c structure of the first gear 31c and the self-locking component 34c structure can serve as a double insurance to ensure the normal operation of the first lifting component 3c.

[0291] In one embodiment of the present disclosure, since the first gear 31c and the second cam plate 38c are coaxial and rotate synchronously, it is necessary to design the relative position relationship between the first gear 31c and the second cam plate 38c, and specifically, it is necessary to define the matching relationship between the toothed portion 311c, the toothless portion 312c and the second flange 381c. The matching relationship between the second flange 381c, the first flange 371c and the toothed portion 311c, the toothless portion 312c is as follows:

[0292] When the toothless portion 312c corresponds to the third gear 33c, before the first gear 31c continues to rotate to make the toothed portion 311c mesh with the third gear 33c, the first flange 371c rotates to leave the self-locking bracket 342c, and the second flange 381c rotates to leave the first one-way locking member 321c. When the toothless portion 312c corresponds to the third gear 33c, the first lifting component 3c is in a decoupled state, and when the first gear 31c continues to rotate to a position where the toothed portion 311c meshes with the third gear 33c, it enters the next lifting cycle, at which time, the first lifting component 3c needs to be restored to a coupled state. In other words, the self-locking bracket 342c needs to be reset to a position where the fourth gear 341c meshes with the second gear 32c and the third gear 33c, and the first one-way locking member 321c needs to re-lock the second gear 32c to keep it rotating in one direction.

[0293] The complete structure and movement of the first lifting assembly 3c have been described above. Fig.38 As shown, the cleaning device of the present invention is also provided with a second lifting component 4c. The specific structure, movement mode and practical application scenario of the second lifting component 4c will be described in detail below.

[0294] In one embodiment of the present disclosure, the cleaning device also includes a second lifting component 4c, which is mainly used in the scenario where the roller brush component 2c overcomes obstacles. The above-mentioned first lifting component 3c can only fine-tune the height position of the roller brush component 2c, and is mainly used in the scenario where the amount of interference between the roller brush component 2c and the working surface is adjusted. When the cleaning device encounters an obstacle, the lifting height of the first lifting component 3c cannot meet the demand. For example, in a commercial cleaning scenario, the cleaning device may encounter obstacles such as thresholds and debris on the cleaning path. At this time, it is necessary to start the second lifting component 4c to drive the roller brush component 2c to rise and overcome the obstacle.

[0295] Specifically, the second lifting assembly 4c is configured to drive the roller brush assembly 2c to rise or fall when the input mechanism in the first lifting assembly 3c is in a decoupled state. When the second lifting assembly 4c drives the roller brush assembly 2c to rise or fall, the transmission rod 22c will rotate with the lifting portion 211c of the connecting frame 21c and the lifting lever 23c, and the output shaft 36c of the first lifting assembly 3c is configured to rotate with the transmission rod 22c. In order to prevent the input shaft 35c from rotating with the output shaft 36c, it is necessary to ensure that the input mechanism of the first lifting assembly 3c is in a decoupled state when the second lifting assembly 4c is operated.

[0296] In one embodiment of the present disclosure, the cleaning device further includes a detection unit for detecting obstacles, and the second lifting component 4c is configured to control the roller brush component 2c to rise based on the electrical signal triggered by the detection unit; and drive the roller brush component 2c to descend after the cleaning device passes over the obstacle. The detection unit may be an infrared obstacle avoidance sensor, which can identify whether there is an obstacle on the walking path of the cleaning device, and if an obstacle is encountered, it can send an electrical signal to the control unit. When the cleaning device runs to a position close to the obstacle, the control unit controls the roller brush component 2c to rise through the second lifting component 4c, and during the obstacle crossing process, the second lifting component 4c can maintain the roller brush component 2c at a high position. After passing the obstacle, the sensor can detect that there is no obstacle in front, and then it will send a descending electrical signal to the control unit, and the control unit controls the roller brush component 2c to descend through the second lifting component 4c to continue cleaning the working surface. The detection unit may also be other types of structures, such as an image acquisition device, so as to determine whether there is an obstacle in front based on the real-time acquired image; the present disclosure does not limit the specific form of the detection unit.

[0297] The second lifting assembly 4c may have various types of structures. In one embodiment of the present disclosure, a connecting rod structure is used to lift the roller brush assembly 2c. Figure 46 to Figure 48 As shown, two brackets 11c are provided, and two opposite side walls of the roller brush assembly 2c are respectively hinged to the machine body 1c through the brackets 11c to limit the roller brush assembly 2c from swinging around the first axis. Providing two brackets 11c to connect the roller brush assembly 2c and the machine body 1c can make the connection of the roller brush assembly 2c more stable, and at the same time, the two brackets 11c can limit the swing direction of the roller brush assembly 2c, thereby achieving vertical lifting.

[0298] The second lifting assembly 4c includes a left swing arm 41c and a right swing arm 42c hinged on the body 1c, and the left swing arm 41c and the right swing arm 42c are configured to be connected through a connecting rod 48c. It should be noted that the "left" and "right" here are only for the convenience of description. Fig.46 The structure on the left side of the figure is named as the left swing arm 41c, and the structure on the right side of the figure is named as the right swing arm 42c. The structures of the two swing arms are completely the same. Fig.46 As shown, the left swing arm 41c and the right swing arm 42c are connected together by a connecting rod 48c, so as to achieve synchronous swinging of the two.

[0299] The free ends of the left swing arm 41c and the right swing arm 42c are configured to slide in cooperation with the guide holes 212c provided in the roller brush assembly 2c. Fig.39A guide hole 212c is also provided on the connecting frame 21c of the roller brush assembly 2c, and the guide hole 212c is constructed as a waist-shaped hole. Sliding nails adapted to the guide block 212c are respectively provided on the free ends of the left swing arm 41c and the right swing arm 42c, so as to slide and fit with the guide holes 212c installed on the connecting frame 21c of the roller brush assembly 2c.

[0300] The second lifting assembly 4c includes a transmission connecting rod, which is configured to be controlled by a driving device 43c to drive the left swing arm 41c and / or the right swing arm 42c to swing around the machine body 1c. Fig.46 and Fig.47 As shown, the driving device 43c includes a motor and a push rod 431c. When the roller brush assembly 2c needs to be lifted, the motor can receive an electrical signal from the control unit to control the push rod 431c to extend. A driving lever 44c is provided in the direction of the free end of the push rod 431c, and the driving lever 44c can be pushed by the push rod 431c. The side of the driving lever 44c pushed by the push rod 431c is a power arm, and the other side is a resistance arm. The end of the resistance arm is constructed to be connected with the transmission connecting rod in a sliding fit. The driving lever 44c rotates through the hinge shaft 441c, and the power arm and the resistance arm are distributed in two different directions of the hinge shaft 441c, so that the driving lever 44c forms a bending structure with the hinge shaft 441c as the inflection point. Further, the power arm of the driving lever 44c can be set to twice the resistance arm, thereby forming a labor-saving lever structure, so that the driving process of the driving device 43c is more labor-saving.

[0301] Fig.46 The second lifting group 4c is shown in its original position. Fig.47 What is shown is the second lifting component 4c in the lifting position. By comparing the two figures, the movement process of the second lifting component 4c can be seen. Among them, the left swing arm 41c and the right swing arm 42c can swing around the body 1c. The top ends of the left swing arm 41c and the right swing arm 42c are respectively hinged on two brackets 11c. The swing axis of the left swing arm 41c and the right swing arm 42c can be defined as the second axis. Compared with the first axis for lifting the roller brush assembly 2c, the second axis is perpendicular to the first axis in space. The present disclosure realizes the steering of the swing direction by setting a connecting rod structure, which ensures that the roller brush assembly 2c does not swing left and right, but is lifted in the vertical direction.

[0302] In a specific embodiment of the present disclosure, the transmission connecting rod includes a first transmission rod 45c, a second transmission rod 46c, and a fixed seat 47c arranged therebetween. One end of the first transmission rod 45c is slidably assembled with the end of the resistance arm of the driving lever 44c, and the other end is slidably assembled with the fixed seat 47c; one end of the second transmission rod 46c is pin-linked with the right swing arm 42c, and the other end is pin-linked with the first transmission rod 45c. When the driving lever 44c swings under the action of the driving device 43c, the first transmission rod 45c can follow the swing and transmit the swing force to the second transmission rod 46c. The second transmission rod 46c can drive the right swing arm 42c to swing along the second axis, and under the transmission action of the connecting rod 48c, the left swing arm 41c can swing parallel to the right swing arm 42c. The free ends of the left swing arm 41c and the right swing arm 42c are respectively slidably matched with the guide holes 212c of the connecting frame 21c on the roller brush assembly 2c, so that the roller brush assembly 2c is driven to swing and rise along the first axis through the connecting frame 21c to overcome obstacles.

[0303] In one embodiment of the present disclosure, the second lifting assembly may further include two sets of auxiliary lifting rods 49c, the upper ends of the auxiliary lifting rods 49c are hinged on the machine body 1c, and the lower ends are fixed on the connecting frame 21c. Fig.39 and Fig.46 The connecting frame 21c may be provided with a connecting portion 213c, and the lower end of the auxiliary lifting rod 49c is hinged to the roller brush assembly 2c through the connecting portion 213c. The auxiliary lifting rod 49c is constructed as a lifting four-link structure. When the roller brush assembly 2c is raised, the auxiliary lifting rods 49c on both sides can share the weight of the roller brush assembly 2c, thereby making the lifting process more labor-saving and more stable, so that the roller brush assembly 2c remains horizontal and does not tilt forward and backward.

[0304] The present disclosure also provides a cleaning device, comprising: a body 1c, a roller brush assembly 2c, a first lifting assembly 3c and a second lifting assembly 4c. The roller brush assembly 2c is configured to clean a working surface; the roller brush assembly 2c is hinged to the body 1c through a bracket 11c, and is configured to move relative to the body 1c toward or away from the working surface.

[0305] The second lifting assembly 4c is configured to drive the roller brush assembly 2c to move between the working position and the obstacle avoidance position; when it is in the working position, the roller brush assembly 2c cooperates with the working surface; when it is in the obstacle avoidance position, the roller brush assembly 2c rises to a predetermined height from the working surface. When the cleaning device is performing cleaning work normally, the roller brush assembly 2c is in the working position, and the roller brush assembly 2c cooperates with the working surface to clean the working surface; and when the cleaning device detects that there is an obstacle in front of the walking path of the roller brush assembly 2c, the second lifting assembly 4c can drive the roller brush assembly 2c to be lifted from the working position to the obstacle avoidance position; after crossing the obstacle, the second lifting assembly 4c drops the roller brush assembly 2c to return to the working position to continue cleaning.

[0306] The first lifting assembly 3c is configured to adjust the relative height between the roller brush assembly 2c and the working surface when the roller brush assembly 2c is in the working position. The first lifting assembly 3c can determine whether the friction between the roller brush assembly 2c and the working surface is within a threshold range by detecting the current of the driving motor 24c; if it is greater than the threshold, the roller brush assembly 2c needs to be raised by the first lifting assembly 3c to reduce the friction; if it is less than the threshold, the roller brush assembly 2c needs to be lowered by the first lifting assembly 3c to increase the friction.

[0307] The cleaning device provided by the present disclosure can not only avoid obstacles through the second lifting component 4c, but also adapt to various types of working surface environments in real time through the first lifting component 3c, so that the cleaning device can be better applied to actual commercial scenarios. Among them, the first lifting component 3c can drive the roller brush component 2c to lift or drop to a suitable position according to the different conditions of the working surface, so as to quickly adapt to various working surfaces, effectively prevent damage to the working surface, extend the life of the roller brush component 2c and its drive motor 24c, and achieve comprehensive cleaning.

[0308] This embodiment also provides a cleaning device. Compared with the cleaning device provided in the first embodiment, the main difference of this embodiment is that the cleaning device is not provided with the first lifting component 3c, but only with the second lifting component 4c. In a commercial cleaning scenario, the cleaning device may encounter obstacles such as thresholds and debris on the cleaning path, and the second lifting component 4c can drive the roller brush component 2c to rise and overcome the obstacles.

[0309] refer to Fig.37 and Fig.38The cleaning device provided in this embodiment includes: a body 1c, a roller brush assembly 2c and a second lifting assembly 4c. The roller brush assembly 2c is configured to clean the working surface and is configured to move toward or away from the working surface relative to the body 1c. The second lifting assembly 4c is configured to drive the roller brush assembly 2c to move between a working position and an obstacle avoidance position; when located at the working position, the roller brush assembly 2c cooperates with the working surface to clean the working surface; when located at the obstacle avoidance position, the roller brush assembly 2c rises to a predetermined height from the working surface to pass over obstacles.

[0310] refer to Figure 46 to Figure 48 The two opposite side walls of the roller brush assembly 2c are respectively hinged to the machine body 1c through two brackets 11c to limit the swing of the roller brush assembly 2c around the first axis. The roller brush assembly 2c is hinged below the machine body 1c to clean the working surface. The two brackets 11c are provided to connect the roller brush assembly 2c and the machine body 1c to make the connection of the roller brush assembly 2c more stable, and the two brackets 11c can also limit the swing direction of the roller brush assembly 2c, thereby achieving vertical lifting.

[0311] The second lifting assembly 4c includes a left swing arm 41c and a right swing arm 42c hinged on the body 1c, and the left swing arm 41c and the right swing arm 42c are configured to be connected via a connecting rod 48c. Fig.46 As shown, the left swing arm 41c and the right swing arm 42c are connected together by a connecting rod 48c, so that the two swing synchronously. The free ends of the left swing arm 41c and the right swing arm 42c are constructed to slide with the guide holes 212c provided in the roller brush assembly 2c. Fig.39 A guide hole 212c is also provided on the connecting frame 21c of the roller brush assembly 2c, and the guide hole 212c is constructed as a waist-shaped hole. Sliding nails adapted to the guide block 212c are respectively provided on the free ends of the left swing arm 41c and the right swing arm 42c, so as to slide and fit with the guide holes 212c installed on the connecting frame 21c of the roller brush assembly 2c.

[0312] The second lifting assembly 4c includes a transmission connecting rod, which is configured to be controlled by a driving device 43c to drive the left swing arm 41c and / or the right swing arm 42c to swing around the machine body 1c. Fig.46 and Fig.47As shown, the driving device 43c includes a motor and a push rod 431c. When the roller brush assembly 2c needs to be lifted, the motor can receive an electrical signal from the control unit to control the push rod 431c to extend. A driving lever 44c is provided in the direction of the free end of the push rod 431c, and the driving lever 44c can be pushed by the push rod 431c. The side of the driving lever 44c pushed by the push rod 431c is a power arm, and the other side is a resistance arm. The end of the resistance arm is constructed to be connected with the transmission connecting rod in a sliding fit. The driving lever 44c rotates through the hinge shaft 441c, and the power arm and the resistance arm are distributed in two different directions of the hinge shaft 441c, so that the driving lever 44c forms a bending structure with the hinge shaft 441c as the inflection point. Further, the power arm of the driving lever 44c can be set to twice the resistance arm, thereby forming a labor-saving lever structure, so that the driving process of the driving device 43c is more labor-saving.

[0313] Fig.46 The second lifting group 4c is shown in its original position. Fig.47 What is shown is the second lifting component 4c in the lifting position. By comparing the two figures, the movement process of the second lifting component 4c can be seen. Among them, the left swing arm 41c and the right swing arm 42c can swing around the body 1c. The top ends of the left swing arm 41c and the right swing arm 42c are respectively hinged on two brackets 11c. The swing axis of the left swing arm 41c and the right swing arm 42c can be defined as the second axis. Compared with the first axis for lifting the roller brush assembly 2c, the second axis is perpendicular to the first axis in space. The present disclosure realizes the steering of the swing direction by setting a connecting rod structure, which ensures that the roller brush assembly 2c does not swing left and right, but is lifted in the vertical direction.

[0314] In a specific embodiment of the present disclosure, the transmission connecting rod includes a first transmission rod 45c, a second transmission rod 46c, and a fixed seat 47c arranged therebetween. One end of the first transmission rod 45c is slidably assembled with the end of the resistance arm of the driving lever 44c, and the other end is slidably assembled with the fixed seat 47c; one end of the second transmission rod 46c is pin-linked with the right swing arm 42c, and the other end is pin-linked with the first transmission rod 45c. When the driving lever 44c swings under the action of the driving device 43c, the first transmission rod 45c can follow the swing and transmit the swing force to the second transmission rod 46c. The second transmission rod 46c can drive the right swing arm 42c to swing along the second axis, and under the transmission action of the connecting rod 48c, the left swing arm 41c can swing parallel to the right swing arm 42c. The free ends of the left swing arm 41c and the right swing arm 42c are respectively slidably matched with the guide holes 212c of the connecting frame 21c on the roller brush assembly 2c, so that the roller brush assembly 2c is driven to swing and rise along the first axis through the connecting frame 21c to overcome obstacles.

[0315] In one embodiment of the present disclosure, the second lifting assembly may further include two sets of auxiliary lifting rods 49c, the upper ends of the auxiliary lifting rods 49c are hinged on the machine body 1c, and the lower ends are fixed on the connecting frame 21c. Fig.39 and Fig.46 The connecting frame 21c may be provided with a connecting portion 213c, and the lower end of the auxiliary lifting rod 49c is hinged to the roller brush assembly 2c through the connecting portion 213c. The auxiliary lifting rod 49c is constructed as a lifting four-link structure. When the roller brush assembly 2c is raised, the auxiliary lifting rods 49c on both sides can share the weight of the roller brush assembly 2c, thereby making the lifting process more labor-saving and more stable, so that the roller brush assembly 2c remains horizontal and does not tilt forward and backward.

[0316] Application scenario 1

[0317] In commercial application scenarios, the cleaning device disclosed in the present invention may be a commercial floor-cleaning robot. The commercial floor-cleaning robot includes a body 1c, a roller brush assembly 2c, and a first lifting assembly 3c. Fig.37 As shown, the roller brush assembly 2c is hinged at the bottom of the body 1c and is configured to clean the working surface. The roller brush assembly 2c of the floor scrubber robot needs to perform cleaning work on various working surfaces in commercial scenarios. On different working surfaces, the appropriate force required for the roller brush assembly 2c of the floor scrubber to clean is different. The roller brush assembly 2c can be moved vertically by the first lifting assembly 3c, so as to adjust the interference between the roller brush assembly 2c and the working surface in real time.

[0318] By setting the first lifting component 3c, the cleaning device can quickly adapt to different working surfaces, thereby meeting the use requirements of commercial scenarios. When it is detected that the force of the roller brush assembly 2c cleaning the working surface is too large, the first lifting component 3c runs to the coupling state to drive the roller brush assembly 2c to be lifted to a position with appropriate force, thereby avoiding damage to the working surface, avoiding excessive wear of the roller brush assembly 2c, and also avoiding overload of the drive motor 24c of the roller brush assembly 2c. When it is detected that the force of the roller brush assembly 2c cleaning the working surface is too small, the first lifting component 3c runs to the decoupling state to make the roller brush assembly 2c fall back to the lowest position, and then runs to the coupling state again to drive the roller brush assembly 2c to be lifted to a position with appropriate force, so that the roller brush assembly 2c can fully clean the working surface.

[0319] In a specific application scenario, when the cleaning device moves from a hard floor to a carpet, the working surface of the roller brush assembly 2c changes from a hard floor to a carpet, the friction coefficient of the working surface increases significantly, and the rotational resistance between the roller brush assembly 2c and the working surface increases significantly. The control component can detect the increase in the rotational resistance between the roller brush assembly 2c and the working surface, and control the first lifting component 3c to lift the roller brush assembly 2c until it is lifted to a height with appropriate resistance. Furthermore, the control unit can determine the friction between the roller brush assembly 2c and the working surface by detecting the current of the drive motor 24c of the roller brush assembly 2c, thereby making adaptive adjustments.

[0320] In addition, the cleaning device of the present disclosure also includes a second lifting component 4c, which is mainly used in the scene where the roller brush component 2c overcomes obstacles. The cleaning device may encounter obstacles such as thresholds and debris on the cleaning path. At this time, the second lifting component 4c needs to be activated to drive the roller brush component 2c to rise and overcome the obstacle.

[0321] The second lifting assembly 4c is constructed to drive the roller brush assembly 2c to move between the working position and the obstacle avoidance position; when in the working position, the roller brush assembly 2c cooperates with the working surface; when in the obstacle avoidance position, the roller brush assembly 2c rises to a predetermined height from the working surface. The cleaning device can detect whether there is an obstacle in front of the walking path. When encountering an obstacle, the second lifting assembly 4c can drive the roller brush 2c to rise to the obstacle avoidance position; after crossing the obstacle, the second lifting assembly 4c can lower the roller brush assembly 2c to the working position. The second lifting assembly 4c uses a connecting rod structure to lift and lower the roller brush assembly 2c labor-savingly and smoothly, thereby meeting the need to cross obstacles.

[0322] The cleaning device provided by the present disclosure can adapt to various types of working surface environments in real time through the first lifting component 3c, and can also avoid obstacles through the second lifting component 4c, so that the cleaning device can be better applied to actual commercial scenarios. Among them, the first lifting component 3c can drive the roller brush component 2c to fine-tune to a suitable height position according to different conditions of the working surface, so as to quickly adapt to various working surfaces, effectively prevent damage to the working surface, extend the life of the roller brush component 2c and its drive motor 24c, and achieve comprehensive cleaning.

[0323] The embodiments of the present disclosure further provide a cleaning device, which may be a self-moving cleaning device well known to those skilled in the art, such as a floor scrubber robot and a sweeping and mopping robot, or a handheld cleaning device well known to those skilled in the art, such as a handheld floor scrubber. In the embodiments of the present disclosure where the cleaning device is a self-moving cleaning device, the self-moving cleaning device moves autonomously on the work surface and cleans the work surface. In the embodiments of the present disclosure where the cleaning device is a handheld floor scrubber, when the user uses the floor scrubber for cleaning, the user may push the floor scrubber to move on the work surface and clean the work surface.

[0324] like Fig.49 and Fig.50 As shown, the cleaning equipment of the present disclosure includes a clean water tank 10d having an overflow channel 11d, and the overflow channel 11d is configured to overflow when the water in the clean water tank 10d reaches a preset water level. It is understandable that a water inlet is provided on the cleaning equipment of the present disclosure, and an overflow pipe 12d is connected to the overflow channel 11d, and the outlet of the overflow port 14d is connected to a drainage structure such as a floor drain. In this way, during the water addition process of the cleaning equipment of the present disclosure, the water level in the clean water tank 10d continues to rise. When the water level in the clean water tank 10d reaches the preset water level, the water in the clean water tank 10d can overflow along the overflow channel 11d and the overflow pipe 12d to the floor drain and other structures, thereby preventing the water in the clean water tank 10d from overflowing from the water inlet.

[0325] Among them, Figure 51 to Figure 54 As shown, a water retaining member 13d is provided at the overflow channel 11d, and the water retaining member 13d includes at least two water retaining sheets 131d distributed axially along the overflow channel 11d, and each water retaining sheet 131d is constructed so that a portion of the edge is connected to the inner wall of the overflow channel 11d, and a gap is formed between the portion of the edge and the inner wall of the overflow channel 11d, and all the water retaining sheets 131d are constructed so that the orthographic projection in the axial direction of the overflow channel 11d covers the radial cross-section of the entire overflow channel 11d.

[0326] Since part of the edge of each water retaining sheet 131d is connected to the inner wall of the overflow channel 11d, a gap is formed between the part of the edge and the inner wall of the overflow channel 11d, so that during the water adding process, when water enters the overflow channel 11d, it can flow out of the overflow channel 11d through the gap between the water retaining sheet 131d and the inner wall of the overflow channel 11d; and since the positive projections of all the water retaining sheets 131d in the axial direction of the overflow channel 11d cover the radial cross-section of the entire overflow channel 11d, so that during the movement of the cleaning equipment, when the water in the clean water tank 10d moves to the overflow channel 11d due to continuous shaking, the water retaining sheet 131d can block the water in the clean water tank 10d from flowing outward, and prevent the water in the clean water tank 10d from flowing out of the overflow pipe 12d to the working surface, thereby effectively improving the user experience.

[0327] like Fig.54 As shown, in one embodiment of the present disclosure, each water retaining sheet 131d is configured to extend obliquely downward from the inner wall of the overflow channel 11d, so that a water retaining groove 132d is formed between the water retaining sheet 131d and the inner wall of the overflow channel 11d.

[0328] Since the water retaining groove 132d is formed between the water retaining sheet 131d and the inner wall of the overflow channel 11d, when the water in the clean water tank 10d hits the water retaining sheet 131d, it will move along the water retaining sheet 131d to the bottom of the water retaining groove 132d, and then move to the inner wall of the overflow channel 11d and flow back into the clean water tank 10d under the influence of gravity. It can be seen that each water retaining sheet 131d extends downwardly from the inner wall of the overflow channel 11d, so that the water retaining groove 132d is formed between the water retaining sheet 131d and the inner wall of the overflow channel 11d, which can effectively prevent the water in the clean water tank 10d from flowing out of the overflow channel 11d after moving along the water retaining sheet 131d to the gap between the water retaining sheet 131d and the inner wall of the overflow channel 11d during the operation of the cleaning device, thereby preventing the water in the clean water tank 10d from flowing out of the overflow pipe 12d onto the working surface.

[0329] like Fig.54 As shown, in one embodiment of the present disclosure, each water retaining sheet 131d is constructed to extend from the inner wall of the overflow channel 11d to exceed the central axis of the overflow channel 11d. Since each water retaining sheet 131d extends from the inner wall of the overflow channel 11d to exceed the central axis of the overflow channel 11d, each water retaining sheet 131d can cover more than half of the radial cross section of the overflow channel 11d, effectively improving the water retaining effect of the water retaining sheet 131d. Fig.54 As shown, in one embodiment of the present disclosure, two water retaining sheets 131d may be provided on opposite sides, with the inner walls of the overflow channel 11d extending beyond the central axis of the overflow channel 11d, so that the orthographic projections of all the water retaining sheets 131d in the axial direction of the overflow channel 11d cover the radial cross-section of the entire overflow channel 11d, thereby effectively reducing the required number of the water retaining sheets 131d and reducing the processing cost of the water retaining sheets 131d.

[0330] Further, such as Fig.53 As shown, in one embodiment of the present disclosure, the orthographic projection area of ​​the water retaining sheet 131d in the axial direction of the overflow channel 11d accounts for 60% to 80% of the cross-sectional area of ​​the overflow channel 11d. Since the orthographic projection area of ​​the water retaining sheet 131d in the axial direction of the overflow channel 11d accounts for 60% to 80% of the cross-sectional area of ​​the overflow channel 11d, it can effectively ensure the water retaining effect of the water retaining sheet 131d, and ensure that the gap between the water retaining sheet 131d and the inner wall of the overflow channel 11d is not too small, ensuring that during the water filling process of the cleaning equipment, when the water level in the clean water tank 10d reaches the preset water level, the water in the clean water tank 10d can overflow from the overflow channel 11d in time.

[0331] Further, such as Fig.54 As shown, in one embodiment of the present disclosure, the water retaining member 13d includes two water retaining sheets 131d, and the projection of the gap between one of the two water retaining sheets 131d and the inner wall of the overflow channel 11d in the axial direction of the overflow channel 11d is located on the projection of the other one in the axial direction of the overflow channel 11d. That is, the two water retaining sheets 131d are arranged in a staggered manner, so that the distance of the positive projection of the gap between the two water retaining sheets 131d and the inner wall of the overflow channel 11d in the axial direction of the overflow channel 11d is relatively far, which can further prevent the water in the water retaining box from flowing out of the overflow channel 11d after moving from the gap between the lower water retaining sheet 131d and the inner wall of the overflow channel 11d to the gap between the upper water retaining sheet 131d and the inner wall of the overflow channel 11d, thereby improving the water retaining effect of the water retaining member 13d.

[0332] In one embodiment of the present disclosure, the clean water tank 10d is provided with an overflow port 14d, the overflow port 14d is configured to enclose an overflow channel 11d, and the water retaining sheet 131d is configured to be integrally formed with the overflow channel 11d. In this way, it is convenient to form the water retaining sheet 131d on the inner wall of the overflow channel 11d, and the water retaining sheet 131d is integrally formed with the overflow channel 11d, which can also reduce the required processing steps of the water retaining sheet 131d.

[0333] And as Fig.51 and Fig.52 As shown, in another embodiment of the present disclosure, an overflow port 14d is provided on the clean water tank 10d; a water retaining member 13d is provided on the overflow port 14d, the water retaining member 13d includes a water retaining member main body 133d, the water retaining member main body 133d is provided with an overflow channel 11d, and the water retaining sheet 131d is constructed to be integrally formed with the overflow channel 11d, so that the water retaining member 13d can be installed on the clean water tank 10d after processing is completed, so that the water retaining member 13d can be easily replaced.

[0334] Further, such as Fig.51 and Fig.55 As shown, the inlet end of the overflow pipe 12d forms a flared structure and is sleeved on the water retaining member 13d, and the pressing plate 15d is configured to press the flared structure of the overflow pipe 12d onto the water retaining member 13d. Since the pressing plate 15d can press the flared structure of the overflow pipe 12d onto the water retaining member 13d, the sealed connection between the water retaining member 13d and the overflow pipe 12d can be ensured, and water is prevented from flowing out of the gap between the water retaining member 13d and the overflow pipe 12d during the overflow process, affecting the user's experience.

[0335] like Fig.49As shown, in order to facilitate users to add water, in one embodiment of the present disclosure, a manual water filling port 21d is provided on the clean water tank 10d; the cleaning device also includes an upper body 90d installed above the clean water tank 10d, and the upper body 90d is penetrated by a water inlet channel 91d, and the water inlet channel 91d is constructed to connect with the manual water filling port 21d through a sealing ring 22d.

[0336] It can be seen that the height of the manual water filling port 21d of the present disclosure is higher than the outlet height of the overflow channel 11d, so that when the water level in the clean water tank 10d reaches the preset water level, the water in the clean water tank 10d can overflow along the overflow channel 11d and the overflow pipe 12d to the floor drain and other structures, thereby preventing the water in the clean water tank 10d from overflowing from the manual water filling port 21d. In addition, by providing a sealing ring 22d between the water inlet channel 91d of the upper body 90d and the manual water filling port 21d of the clean water tank 10d, it can effectively prevent the water in the clean water tank 10d from flowing out from the gap between the upper body 90d and the clean water tank 10d during the water filling process and the working process of the cleaning device, effectively improving the user experience.

[0337] like Fig.56 and Fig.57 As shown, in one embodiment of the present disclosure, a drain port 31d is provided at the bottom of the clean water tank 10d, and a drain valve 32d is provided on the drain port 31d. The drain valve 32d is configured to drain the water in the clean water tank 10d when opened. By providing the drain valve 32d at the bottom of the clean water tank 10d, the water in the clean water tank 10d can be quickly drained without disassembling the clean water tank 10d to drain the water during maintenance or storage, thereby facilitating subsequent maintenance or storage.

[0338] Specifically, Fig.58 As shown, an opening knob is provided on the drain valve 32d. When the user needs to empty the clean water tank 10d, the user connects the drain pipe 34d to the drain valve 32d, and the user can drain the water in the clean water tank 10d by rotating the opening knob to the open state; after the water in the clean water tank 10d is emptied, the user can close the drain valve 32d by rotating the opening knob to the closed state.

[0339] Among them, Fig.59 As shown, in one embodiment of the present disclosure, a mounting nut 33d is fixedly provided on the drain port 31d; and the inlet of the drain valve 32d is connected to the mounting nut 33d by a thread. By fixing the mounting nut 33d on the drain port 31d, the drain valve 32d can be easily installed on the clean water tank 10d. In order to prevent the water in the clean water tank 10d from flowing out from the gap between the mounting nut 33d and the drain valve 32d, a sealing ring can be provided between the gap between the mounting nut 33d and the drain valve 32d.

[0340] like Fig.50 and Fig.60 As shown, in one embodiment of the present disclosure, a water injection member 41d having a water injection channel 43d is provided on the clean water tank 10d, and the water injection channel 43d is constructed to extend in the horizontal direction; the outlet of the water injection channel 43d is movably provided with a baffle 42d, and the baffle 42d is constructed to cover the outlet of the water injection channel 43d under the action of its own elastic force, and to overcome its own elastic force to open the outlet of the water injection channel 43d when external water enters the water injection channel 43d. It can be understood that the water injection member 41d of the present disclosure can be used in conjunction with a base station with a water injection function. When it is necessary to use the base station to add water to the cleaning equipment, the cleaning equipment can be docked with the base station, and the water injection pipe on the base station can penetrate into the water injection channel 43d, and overcome the elastic force of the baffle 42d to open the outlet of the water injection channel 43d, and then water can be injected into the clean water tank 10d. After the water filling is completed and the water filling pipe on the base station is recovered, the baffle 42d can cover the outlet of the water filling channel 43d again to prevent the water in the clean water tank 10d from overflowing from the water filling channel 43d during the operation of the cleaning device.

[0341] like Fig.49 and Fig.50 As shown, in one embodiment of the present disclosure, the top of the clean water tank 10d is constructed to extend upward to form a first protrusion 51d, and a second protrusion 52d separated from the first protrusion 51d; the manual water filling port 21d is arranged on the first protrusion 51d, and the water filling member 41d is arranged on the second protrusion 52d.

[0342] Since the manual water filling port 21d is arranged on the first protrusion 51d, the water filling member 41d is arranged on the second protrusion 52d, and the first protrusion 51d and the second protrusion 52d are spaced apart from each other, during the water adding process, even when the amount of water is large, water entering the clean water tank 10d from the manual water filling port 21d or the water filling member 41d will be blocked by the inner wall of the clean water tank 10d and will not flow out from the other. In this way, it can be effectively prevented that the water in the clean water tank 10d flows out from the manual water filling port 21d or the water filling member 41d during the water adding process.

[0343] Further, such as Fig.49 and Fig.50 As shown, in one embodiment of the present disclosure, the first protrusion 51d is configured to be disposed on the first side wall 53d of the clean water tank 10d, and the second protrusion 52d is configured to be disposed at least on the second side wall 54d of the clean water tank 10d. During the water filling process, the direction of water entering from the manual water filling port 21d will not be toward the direction of the water filling member 41d, and the direction of water entering from the water filling member 41d will not be toward the direction of the manual water filling port 21d, which can further prevent the water in the clean water tank 10d from flowing out from the manual water filling port 21d or the water filling member 41d during the water filling process.

[0344] like Fig.61 As shown, in one embodiment of the present disclosure, the clean water tank 10d is provided with a detection assembly; the detection assembly includes a mounting rod 61d and at least two water level detection units 62d, the mounting rod 61d is configured to extend in the height direction, and each water level detection unit 62d is arranged at intervals on the mounting rod 61d, and is configured to trigger a water level signal when the water in the clean water tank 10d reaches a corresponding position. By arranging at least two water level detection units 62d at intervals on the mounting rod 61d, a water level signal is triggered when the water in the clean water tank 10d reaches a corresponding position, thereby prompting the user with signals such as the water in the clean water tank 10d is full, the water is used up, etc., or triggering water level signals such as a full signal and an empty signal, so that it is convenient for the cleaning device to stop adding water or go to the base station to add water.

[0345] Specifically, Fig.61 As shown, in one embodiment of the present disclosure, three water level detection units 62d are arranged at intervals on the mounting rod 61d, and each water level detection unit 62d can correspond to a high water level, a low water level, and a medium water level signal, respectively. In other embodiments of the present disclosure, the number and position of the water level detection unit 62d can also be set as needed, which will not be repeated here.

[0346] In one embodiment of the present disclosure, the water level detection unit 62d includes a water level detection float 621d and a trigger 622d, the water level detection float 621d is configured to move within a preset range, the trigger 622d is arranged within the movement range of the water level detection float 621d, and is configured to trigger a water level signal when in contact with the water level detection float 621d. In this way, during the operation of the water level detection unit 62d, when the trigger 622d is arranged above the water level monitoring float, when the water level reaches the water level corresponding to the trigger 622d, the water level detection float 621d moves upward to contact with the water level detection float 621d to trigger the water level signal; when the trigger 622d is arranged below the water level monitoring float, when the water level reaches the water level corresponding to the trigger 622d, the water level detection float 621d moves downward to contact with the water level detection float 621d to trigger the water level signal. It can be seen that the water level detection unit 62d of the present disclosure has a simple principle and high detection accuracy.

[0347] In one embodiment of the present disclosure, a trigger member 622d may be provided above and below the water level detection float 621d. Fig.61 As shown, in another embodiment of the present disclosure, the trigger member 622d may be provided only above the water level detection float 621d, which is not limited here.

[0348] Specifically, in one embodiment of the present disclosure, the movable range of the water level detection float 621d is 5 mm to 10 mm, so that the detection accuracy of the water level detection unit 62d can be effectively guaranteed while limiting the movable range of the water level detection float 621d.

[0349] The present disclosure also provides a clean water tank 10d, the clean water tank 10d having an overflow channel 11d, the overflow channel 11d being configured to overflow when the water in the clean water tank 10d reaches a preset water level;

[0350] Among them, a water retaining member 13d is provided at the overflow channel 11d, and the water retaining member 13d includes at least two water retaining sheets 131d distributed axially along the overflow channel 11d, and each water retaining sheet 131d is constructed so that a partial edge is connected to the inner wall of the overflow channel 11d, and a gap is formed between the partial edge and the inner wall of the overflow channel 11d, and all the water retaining sheets 131d are constructed so that the orthographic projection in the axial direction of the overflow channel 11d covers the radial cross-section of the entire overflow channel 11d.

[0351] Since part of the edge of each water retaining sheet 131d is connected to the inner wall of the overflow channel 11d, a gap is formed between the part of the edge and the inner wall of the overflow channel 11d, so that during the water adding process, when water enters the overflow channel 11d, it can flow out of the overflow channel 11d through the gap between the water retaining sheet 131d and the inner wall of the overflow channel 11d; and since the positive projections of all the water retaining sheets 131d in the axial direction of the overflow channel 11d cover the radial cross-section of the entire overflow channel 11d, so that during the movement of the cleaning equipment, when the water in the clean water tank 10d moves to the overflow channel 11d due to continuous shaking, the water retaining sheet 131d can block the water in the clean water tank 10d from flowing outward, and prevent the water in the clean water tank 10d from flowing out of the overflow pipe 12d to the working surface, thereby effectively improving the user experience.

[0352] Application Scenario

[0353] The present disclosure provides a cleaning device, which may be a self-moving cleaning device well known to those skilled in the art, such as a floor scrubber robot and a sweeping and mopping robot, or a handheld cleaning device well known to those skilled in the art, such as a handheld floor scrubber. In an embodiment in which the cleaning device of the present disclosure is a self-moving cleaning device, the self-moving cleaning device moves autonomously on a work surface and cleans the work surface. In an embodiment in which the cleaning device of the present disclosure is a handheld floor scrubber, when a user uses the floor scrubber for cleaning, the user may push the floor scrubber to move on the work surface and clean the work surface.

[0354] The cleaning device of the present disclosure includes a clean water tank 10d having an overflow channel 11d, and the overflow channel 11d is configured to overflow when the water in the clean water tank 10d reaches a preset water level. It is understandable that a water inlet is provided on the cleaning device of the present disclosure, and an overflow pipe 12d is connected to the overflow channel 11d, and the outlet of the overflow port 14d is connected to a drainage structure such as a floor drain. In this way, during the water addition process of the cleaning device of the present disclosure, the water level in the clean water tank 10d continues to rise, and when the water level in the clean water tank 10d reaches the preset water level, the water in the clean water tank 10d can overflow along the overflow channel 11d and the overflow pipe 12d to the structure such as the floor drain, thereby preventing the water in the clean water tank 10d from overflowing from the water inlet.

[0355] Among them, a water retaining member 13d is provided at the overflow channel 11d, and the water retaining member 13d includes at least two water retaining sheets 131d distributed axially along the overflow channel 11d, and each water retaining sheet 131d is constructed so that a partial edge is connected to the inner wall of the overflow channel 11d, and a gap is formed between the partial edge and the inner wall of the overflow channel 11d, and all the water retaining sheets 131d are constructed so that the orthographic projection in the axial direction of the overflow channel 11d covers the radial cross-section of the entire overflow channel 11d.

[0356] Since part of the edge of each water retaining sheet 131d is connected to the inner wall of the overflow channel 11d, a gap is formed between the part of the edge and the inner wall of the overflow channel 11d, so that during the water adding process, when water enters the overflow channel 11d, it can flow out of the overflow channel 11d through the gap between the water retaining sheet 131d and the inner wall of the overflow channel 11d; and since the positive projections of all the water retaining sheets 131d in the axial direction of the overflow channel 11d cover the radial cross-section of the entire overflow channel 11d, so that during the movement of the cleaning equipment, when the water in the clean water tank 10d moves to the overflow channel 11d due to continuous shaking, the water retaining sheet 131d can block the water in the clean water tank 10d from flowing outward, and prevent the water in the clean water tank 10d from flowing out of the overflow pipe 12d to the working surface, thereby effectively improving the user experience.

[0357] The embodiments of the present disclosure further provide a cleaning device, a dirt storage component, and a main unit, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present disclosure. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0358] In the prior art, the cleaning device includes a main unit and a dirt storage tank. The dirt storage tank is used to store the wastewater generated during the cleaning process of the main unit. The dirt storage tank is inseparable from the main unit. Inseparability here means that the user cannot easily remove the dirt storage tank from the main unit without the help of tools, or even if the dirt storage tank is removed from the main unit, the cleaning device will lose its function. For example, the circuit connection relationship between the dirt storage tank and the main unit cannot be restored, and the fluid channel between the dirt storage tank and the main unit is interrupted.

[0359] Since the dirt storage tank is inseparable from the main unit, it is inconvenient to clean the dirt storage tank. At the same time, when cleaning the dirt storage tank, water may easily enter the main unit, causing a short circuit risk.

[0360] In view of this, the embodiments of the present disclosure provide a cleaning device, a dirt storage assembly, and a main machine to improve the convenience of cleaning a dirt storage box.

[0361] See also Fig.62 and Fig.63 , Fig.62 is a three-dimensional structural schematic diagram of a cleaning device according to an embodiment of the present disclosure, in which a dirt storage component is installed on a main machine. Fig.63 It is a three-dimensional structural schematic diagram of the separation of the dirt storage component and the main body in one embodiment of the cleaning device disclosed in the present invention.

[0362] In some embodiments, the cleaning device 10e is a cleaning robot with cleaning functions such as washing, sweeping, and mopping. The cleaning device 10e can move on the surface to be cleaned to clean the surface to be cleaned. The surface to be cleaned can be the ground, or the target surface of an object. The liquid dirt generated by the cleaning device 10e during the cleaning process is collected and discharged uniformly. The dirt is, for example, a mixture of cleaning liquid, water, dust, and debris, and is liquid as a whole. In some cases, the dirt is also mixed with large particles of debris, such as scraps of paper, but the dirt is flowable as a whole.

[0363] In some embodiments, the cleaning device 10e is a commercial floor scrubber. Specifically, the cleaning device 10e has a brush, which is soaked in a liquid (e.g., a mixture of cleaning liquid and water) and rotates and rubs on the surface to be cleaned, thereby cleaning the surface to be cleaned. The liquid is mixed with the dirt on the surface to be cleaned to form the above-mentioned dirt. The cleaning device 10e can vacuum and collect the dirt so that the brush remains clean.

[0364] In some embodiments, the cleaning device 10e can move autonomously according to the planned path. In other embodiments, the cleaning device 10e moves under the drive of the user.

[0365] In some embodiments, the cleaning device 10e moves to a base station (not shown) and discharges waste after docking with the base station. The base station is used to collect the dirt stored by the cleaning device 10e. In other embodiments, the user drives the cleaning device 10e to move to a waste discharge location (such as a sewer) for discharge.

[0366] The cleaning device 10e includes a main body 100e and a dirt storage component 200e.

[0367] The host 100e is used for cleaning. The host 100e generates dirt during the cleaning process and recovers the dirt. The dirt storage component 200e is detachably mounted on the host 100e and is used to store the dirt recovered by the host 100e.

[0368] In some embodiments, the host 100e has a mounting cavity 104e, and the mounting cavity 104e is vertically opened upward to form a first opening 106e. The dirt storage assembly 200e is accommodated in the mounting cavity 104e. The dirt storage assembly 200e is carried by the host 100e and is kept fixed in position under the restriction of the side wall at the mounting cavity 104e of the host 100e. The dirt storage assembly 200e can be separated from the mounting cavity 104e through the first opening 106e under the action of an external force to separate from the host 100e. That is, the user can pull the dirt storage assembly 200e upward to separate the dirt storage assembly 200e from the host 100e.

[0369] In other embodiments, the first opening 106e of the installation cavity 104e is open in the horizontal direction, and the dirt storage assembly 200e can be taken out by pulling it in the horizontal direction.

[0370] In other embodiments, the sewage storage component 200e is hung on the main unit 100e, and the user can pull up the sewage storage component 200e to separate the sewage storage component 200e from the main unit 100e.

[0371] In some other embodiments, the sewage storage assembly 200e is connected to the main body 100e through a quick-release structure. The quick-release structure enables the user to separate the sewage storage assembly 200e from the main body 100e without using tools. For example, the sewage storage assembly 200e is buckled with the main body 100e through a buckle, or is locked to the main body 100e through a handle described below.

[0372] The connection method between the dirt storage component 200e and the host 100e is not limited. The user can separate the dirt storage component 200e from the host 100e and install the dirt storage component 200e on the host 100e again as long as the function of the cleaning device 10e is not affected.

[0373] When the dirt storage component 200e is installed on the main unit 100e, it can store dirt and discharge the dirt through the main unit 100e. When the dirt storage component 200e is separated from the main unit 100e, it is convenient to clean the dirt storage component 200e.

[0374] See also Fig.64 , Fig.64 It is a schematic diagram of the principle of an embodiment of the cleaning device disclosed in the present invention.

[0375] The host machine 100e has a first drain passage 110e.

[0376] The sewage storage assembly 200e includes a sewage storage tank 202e and a sewage pump 214e.

[0377] The dirt storage box 202e is detachably mounted on the main unit 100e. The dirt storage box 202e has a dirt storage chamber 208e and a second dirt discharge passage 274e connected to each other. The dirt storage chamber 208e is used to store dirt recovered by the main unit 100e.

[0378] The sewage pump 214e is disposed in the sewage storage tank 202e, and the sewage pump 214e is connected to the second sewage discharge channel 274e. The second sewage discharge channel 274e is used to connect with the first sewage discharge channel 110e when the sewage storage tank 202e is installed in the main unit 100e, and the sewage pump 214e is used to drive the dirt in the sewage storage chamber 208e to be discharged through the second sewage discharge channel 274e and the first sewage discharge channel 110e in sequence.

[0379] Specifically, when the dirt storage box 202e is installed on the main unit 100e, the first drain channel 110e and the second drain channel 274e are connected. When the dirt storage box 202e is separated from the main unit 100e, the first drain channel 110e and the second drain channel 274e are interrupted.

[0380] In some embodiments, the host 100e has a sewage outlet 112e. The first sewage outlet channel 110e is connected to the sewage outlet 112e. The dirt in the sewage storage chamber 208e is discharged through the second sewage outlet channel 274e, the first sewage outlet channel 110e and the sewage outlet 112e in sequence. When the host 100e cooperates with the base station to discharge sewage, the host 100e is connected to the base station through the sewage outlet 112e, and the dirt is discharged to the base station through the sewage outlet 112e.

[0381] Since the dirt storage box 202e can be detachably mounted on the host 100e, when the dirt storage box 202e needs to be cleaned, the dirt storage box 202e can be removed from the host 100e for cleaning, thereby improving the convenience of cleaning the dirt storage box 202e. When the dirt storage box 202e is installed on the host 100e, the sewage pump 214e provided in the dirt storage box 202e can drive the dirt in the dirt storage chamber 208e to be discharged through the second sewage discharge channel 274e and the first sewage discharge channel 110e in sequence, so that the cleaning device 10e can actively discharge the dirt through the host 100e, avoiding the active sewage discharge trouble caused by the detachable dirt storage box 202e. For example, when the dirt in the dirt storage chamber 208e reaches the upper limit, the host 100e moves autonomously to dock with the base station to discharge the dirt. In this way, the user participation is reduced.

[0382] In the disclosed embodiment, the cleaning device 10e is not limited to discharging sewage only through the main unit 100e. In some embodiments, after the sewage storage tank 202e is separated from the main unit 100e, the sewage pump 214e drives the dirt in the sewage storage chamber 208e to be directly discharged through the second sewage discharge channel 274e.

[0383] See also Fig.65 , Fig.65 It is a schematic diagram of the three-dimensional structure of the dirt storage assembly 200e in one embodiment of the cleaning device disclosed in the present invention (viewed from the bottom, with the protective shell omitted).

[0384] In some embodiments, the sewage storage tank 202e includes a tank body 204e and a sewage discharge pipe 218e. The tank body 204e has the sewage storage chamber 208e described above. The sewage discharge pipe 218e is located outside the tank body 204e. The sewage discharge pipe 218e is connected to the sewage storage chamber 208e. A second sewage discharge channel 274e is formed in the sewage discharge pipe 218e. The sewage discharge pump 214e is fixed to the tank body 204e, and the sewage discharge pump 214e is connected to the sewage discharge pipe 218e.

[0385] Specifically, the sewage pipe 218e can be a flexible pipe, such as a corrugated pipe, etc. In this way, it is easier to assemble. In other embodiments, the sewage pipe 218e can also be a rigid pipe.

[0386] Compared with disposing the sewage pump 214e in the sewage storage chamber 208e, disposing the sewage pump 214e outside the box body 204e can reduce the requirements for the sealing of the sewage pump 214e and increase the service life of the sewage pump 214e.

[0387] Please also read Fig.66 , Fig.66 Schematic diagram of the cross-sectional structure of the dirt storage assembly in one embodiment of the cleaning device 10e disclosed in the present invention.

[0388] Specifically, the sewage pipe 218e is connected to the bottom wall 258e of the box body 204e, so that all the dirt in the dirt storage chamber 208e can enter the sewage pipe 218e, so that the dirt storage chamber 208e can be emptied. In some embodiments, the bottom surface of the dirt storage chamber 208e has an inclined surface (not shown), which is inclined downward to guide the dirt into the sewage pipe 218e.

[0389] In order to prevent dirt from clogging the sewage pipe 218e, a first filter 248e is further provided in the sewage storage chamber 208e. The first filter 248e is generally a cylindrical filter screen, which is provided at the connection between the sewage pipe 218e and the sewage storage chamber 208e. In this way, large particles in the dirt can be filtered by the first filter 248e, reducing the probability of the sewage pipe 218e being blocked.

[0390] Specifically, the sewage pump 214e has an inlet 254e and an outlet 256e, and the inlet 254e and the outlet 256e of the sewage pump 214e are both connected to the sewage pipe 218e. The sewage pump 214e can be an existing water pump. The sewage pump 214e can pump out the dirty sewage in the sewage pipe 218e.

[0391] In some embodiments, the sewage pump 214e is disposed below the box 204e. Specifically, when the cleaning device 10e is in use, the projection of the sewage pump 214e is located within the projection of the bottom wall 258e of the box 204e, with the horizontal plane as the projection plane. In the case where the sewage storage component 200e is detachably mounted on the main machine 100e by being accommodated in the mounting cavity 104e of the main machine 100e, if the sewage pump 214e is disposed on the side of the box 204e, a bulge will be formed on the side of the box 204e, thereby making it difficult for the side wall of the box 204e to be limited and matched with the side wall of the mounting cavity 104e. By disposing the sewage pump 214e below the box 204e, it is possible to avoid the sewage pump 214e from affecting the limited and matched position between the box 204e and the main machine 100e. In addition, it is possible to reduce the size of the sewage storage component 200e in the horizontal direction, thereby reducing the size of the cleaning device 10e in the horizontal direction.

[0392] Please also read Fig.67 , Fig.67 It is a schematic diagram of the three-dimensional structure of the dirt storage assembly in one embodiment of the cleaning device disclosed herein (viewed from the top).

[0393] In some embodiments, the sewage storage tank 202e further includes a protective shell 220e. The protective shell 220e is connected to the box body 204e to form a receiving chamber 222e, and the sewage pump 214e is received in the receiving chamber 222e.

[0394] Since the sewage pump 214e is fixed outside the box 204e, when cleaning the box 204e, liquid (cleaning liquid or water) can easily contaminate the sewage pump 214e, for example, the liquid flows along the outer wall of the box 204e to the sewage pump 214e. When the powered parts in the sewage pump 214e are contaminated by liquid, the sewage pump 214e may be short-circuited or damaged. By providing the protective shell 220e, the probability of liquid contaminating the sewage pump 214e can be reduced, thereby reducing the risk of short-circuiting or damaging the sewage pump 214e.

[0395] When the sewage pump 214e is located below the box body 204e, the protective shell 220e is a shell with an open top, and the protective shell 220e is located below the box body 204e, and the cover is arranged at the bottom of the box body 204e, and docks with the box body 204e to form a accommodating chamber 222e. The provision of the protective shell 220e can play a role in structural support. The sewage storage component 200e is carried on the main unit 100e through the protective shell 220e. If the protective shell 220e is not provided, the box body 204e will vertically squeeze the sewage pump 214e and the sewage pipe 218e, which may easily cause damage to the sewage pump 214e and the sewage pipe 218e.

[0396] In some embodiments, the protective shell 220e is detachably connected to the housing 204e, for example, by bolts. This arrangement facilitates inspection and maintenance when leakage occurs at the connection between the sewage pump 214e and the sewage pipe 218e, or at the connection between the sewage pipe 218e and the housing 204e. At the same time, it is also convenient to assemble the sewage pump 214e and the sewage pipe 218e to the housing 204e.

[0397] like Fig.65 As shown, in some embodiments, the sewage pipe 218e includes a first pipe section 282e and a second pipe section 284e. The first pipe section 282e is disposed at the bottom of the box 204e. The sewage pump 214e is connected to the first pipe section 282e. The second pipe section 284e is disposed at the side of the box 204e. The top of the box 204e is provided with a second sewage interface 212e for connecting to the first sewage channel 110e. The first pipe section 282e is connected to the second sewage interface 212e through the second pipe section 284e.

[0398] Specifically, the first pipe section 282e includes a first subsection 283e, a second subsection 287e and a third subsection 289e. One end of the first subsection 283e is connected to the bottom wall 258e of the box body 204e and communicates with the sewage storage chamber 208e. The other end of the first subsection 283e is connected to the inlet 254e of the sewage pump 214e. One end of the second subsection 287e is connected to the outlet 256e of the sewage pump 214e, and the other end is connected to the valve 224e (described in detail below). One end of the third subsection 289e is connected to the valve 224e, and the other end is connected to the second pipe section 284e.

[0399] Specifically, the side wall of the box body 204e is further provided with a first accommodating groove 288e to accommodate the second pipe section 284e, thereby keeping the side wall of the dirt storage box 202e flat.

[0400] The second sewage discharge interface 212e is arranged at the top of the box body 204e, which reduces the risk of dirt leakage at the second sewage discharge interface 212e compared to the second sewage discharge interface 212e being arranged at the bottom of the box body 204e. In this proposal, the first pipe section 282e is arranged at the bottom of the box body 204e, and is connected to the second sewage discharge interface 212e through the second pipe section 284e extending vertically, which not only realizes the connection of the sewage pipe 218e, but also reduces the risk of dirt leakage.

[0401] See also Fig.64 , Fig.65 as well as Fig.68 . Fig.68 It is a schematic diagram of the three-dimensional structure of the main unit in one embodiment of the cleaning device disclosed herein (viewed from the top).

[0402] In some embodiments, the host 100e further comprises a power supply 126e and a first conductive member 130e electrically connected to each other. The sewage storage assembly 200e further comprises a second conductive member 216e. The second conductive member 216e is disposed in the sewage storage tank 202e and electrically connected to the sewage pump 214e. Fig.64 The first conductive member 130e is used to connect with the second conductive member 216e when the sewage storage tank 202e is installed on the main unit 100e, so that the power supply member 126e supplies power to the sewage pump 214e.

[0403] In some embodiments, the first conductive member 130e and the second conductive member 216e are respectively made of copper or copper alloy.

[0404] In some embodiments, the power supply 126e is a battery, so that the cleaning device 10e has its own power supply. The power supply 126e supplies power to the host 100e on the one hand, and supplies power to the sewage pump 214e on the other hand. In other embodiments, the cleaning device 10e does not have a power supply. The power supply 126e is a component electrically connected to the power grid, for example, the power supply 126e is a plug or a transformer. The power grid supplies power to the sewage pump 214e through the power supply 126e.

[0405] In some embodiments, the first conductive member 130e can float vertically, and / or the second conductive member 216e can float vertically. Under the action of its own gravity, the dirt storage tank 202e makes the first conductive member 130e and the second conductive member 216e abut vertically. Thus, the contact effect between the first conductive member 130e and the second conductive member 216e can be improved, thereby improving the electrical connection effect.

[0406] Furthermore, the top of the dirt storage box 202e has a protrusion 290e protruding to one side in the horizontal direction. The second conductive member 216e is disposed on the protrusion 290e and exposed at the bottom of the protrusion 290e. When the dirt storage assembly 200e is installed on the main unit 100e, the protrusion 290e is pressed against the main unit 100e.

[0407] Specifically, Fig.68 In the illustrated embodiment, there are two first conductive members 130e, one of which is a positive electrode and the other is a negative electrode. Fig.65 In the illustrated embodiment, there are two second conductive members 216e, one second conductive member 216e is a positive electrode, and the other second conductive member 216e is a negative electrode. The positive first conductive member 130e abuts against the positive second conductive member 216e, and the negative first conductive member 130e abuts against the negative second conductive member 216e.

[0408] See also Fig.64 and Fig.65 In some embodiments, the sewage storage assembly 200e further includes a valve 224e. The valve 224e is connected to the second sewage discharge channel 274e, and the valve 224e is used to selectively block or open the second sewage discharge channel 274e.

[0409] When the dirt storage box 202e forms a negative pressure environment in the dirt storage chamber 208e to suck dirt from the host 100e (see below for details), the valve 224e can be set to form a closed space in the dirt storage chamber 208e in the non-discharge state.

[0410] In some embodiments, along the direction in which dirt is discharged from the dirt storage chamber 208e through the second dirt discharge channel 274e, the valve 224e is arranged on the downstream side of the dirt pump 214e. The valve 224e is configured to, along the direction in which dirt is discharged from the dirt storage chamber 208e through the second dirt discharge channel 274e, when the pressure on the valve 224e is greater than a predetermined value, the valve 224e conducts the second dirt discharge channel 274e, otherwise, the valve 224e blocks the second dirt discharge channel 274e. The predetermined value may be the pressure at which the dirt is pumped by the dirt pump 214e. When the dirt pump 214e is working, the valve 224e conducts the second dirt discharge channel 274e. When the dirt pump 214e stops working, the valve 224e blocks the second dirt discharge channel 274e.

[0411] See also Fig.69 . Fig.69 Schematic diagram of a handle locking structure in an embodiment of the cleaning device disclosed herein.

[0412] In some embodiments, the dirt storage assembly 200e further includes a handle 226e. The handle 226e is movably disposed on the dirt storage box 202e, and the handle 226e is used for a user to hold and also for locking the dirt storage box 202e to the host 100e.

[0413] Taking the case where the dirt storage assembly 200e is accommodated in the installation cavity 104e as an example, how the handle 226e locks the dirt storage box 202e to the main unit 100e is described.

[0414] Specifically, the handle 226e is rotatably disposed on the dirt storage box 202e around the axis L1e. As the handle 226e rotates, the handle 226e can switch between a locked position and an unlocked position. Fig.69 The handle 226e shown by the solid line is in an unlocked position. Fig.69 The handle 226e shown by the middle dotted line is in a locked position. In the locked position, the dirt storage assembly 200e is locked to the main unit 100e. In the unlocked position, the lock is released.

[0415] The handle 226e includes a gripping portion 285e and a limiting protrusion 286e. The gripping portion 285e is rotatably disposed on the dirt storage box 202e around the axis L1e. The gripping portion 285e is used for a user to hold. The limiting protrusion 286e extends in the direction of the axis L1e and is convexly disposed on the end surface of the gripping portion 285e along one end of the axis L1e. The limiting protrusion 286e is located outside the axis L1e so that the position of the limiting protrusion 286e relative to the dirt storage box 202e changes with the rotation of the gripping portion 285e. The limiting protrusion 286e can be selectively in a locked position or an unlocked position with the rotation of the gripping portion 285e.

[0416] The cleaning device 10e has an assembly direction F, and the dirt storage box 202e is installed on the main machine 100e along the assembly direction F. Specifically, the assembly direction F may be a gravity direction.

[0417] The host 100e has a stopper 136e. When the limit protrusion 286e is in a locked position, the limit protrusion 286e is opposite to the stopper 136e in the assembly direction F, and the stopper 136e limits the separation of the dirt storage box 202e from the host 100e through the limit protrusion 286e. When the limit protrusion 286e is in an unlocked position, the limit protrusion 286e is staggered with the stopper 136e to allow the dirt storage box 202e to separate from the host 100e. Specifically, Fig.69In the illustrated embodiment, when the limiting protrusion 286e is in the locking position, the limiting protrusion 286e is located below the stopper 136e, and when the dirt storage box 202e moves upward, the stopper 136e blocks the dirt storage box 202e from moving. When the limiting protrusion 286e is in the unlocking position, the limiting protrusion 286e leaves the bottom of the stopper 136e, and when the dirt storage box 202e moves upward, the stopper 136e does not block the dirt storage box 202e from moving.

[0418] Specifically, the main machine 100e has a guide groove 131e, one end of the guide groove 131e is open and the other end is closed. The stopper 136e is located at the closed end of the guide groove 131e. When the dirt storage component 200e is installed on the main machine 100e, the limiting protrusion 286e is clamped in the guide groove 131e. When the limiting protrusion 286e is in a locked state, the limiting protrusion 286e is located at the closed end of the guide groove 131e and is restricted in the guide groove 131e. When the limiting protrusion 286e is in an unlocked state, the limiting protrusion 286e can be separated from the guide groove 131e through the open end of the guide groove 131e.

[0419] Specifically, the guide groove 131e includes a first guide portion 132e and a second guide portion 134e. The first guide portion 132e is open toward the mounting cavity 104e. The first guide portion 132e extends inward from the edge of the first opening 106e of the mounting cavity 104e. The second guide portion 134e is open toward the mounting cavity 104e. The second guide portion 134e is connected to the extended end of the first guide portion 132e and extends along an arc path. The starting end of the first guide portion 132e is open, the starting end of the second guide portion 134e is connected to the end of the first guide portion 132e, and the end of the second guide portion 134e is closed. When the dirt storage component 200e is installed on the host 100e, the center line of the second guide portion 134e is the axis L1e.

[0420] When the handle 226e is in the unlocked position, the user places the dirt storage assembly 200e into the installation cavity 104e through the first opening 106e. During the process of placing the dirt storage assembly 200e into the installation cavity 104e, the limiting protrusion 286e is clamped on the first guide portion 132e and moves along the first guide portion 132e. After the dirt storage assembly 200e is completely accommodated in the installation cavity 104e, the limiting protrusion 286e moves to the end of the first guide portion 132e and enters the starting end of the second guide portion 134e. The user drives the handle 226e to rotate to the locked position, so that the limiting protrusion 286e rotates around the axis L1e (the limiting protrusion 286e shown in the solid line rotates to the limiting protrusion 286e shown in the dotted line). During the process of the limiting protrusion 286e rotating around the axis L1e, it moves along the second guide portion 134e to the end of the second guide portion 134e. Since the end of the second guide portion 134e is closed, the host 100e can resist the limiting protrusion 286e, so that the dirt storage component 200e cannot be separated from the installation cavity 104e.

[0421] When the handle 226e is in the locked position, the user drives the handle 226e to rotate to the unlocked position, so that the limiting protrusion 286e rotates around the axis L1e (the limiting protrusion 286e shown in the dotted line rotates to the limiting protrusion 286e shown in the solid line). During the rotation of the limiting protrusion 286e around the axis L1e, it moves along the second guide portion 134e to the starting end of the second guide portion 134e and enters the end of the first guide portion 132e. The user pulls the dirt storage assembly 200e out of the installation cavity 104e.

[0422] In other embodiments, the handle 226e may be used only for facilitating the user's holding, but not for locking the dirt storage box 202e.

[0423] See also Fig.64 , Fig.65 as well as Fig.68 In some embodiments, the host 100e further comprises a first sewage discharge interface 108e connected to the first sewage discharge channel 110e. The sewage storage box 202e further comprises a second sewage discharge interface 212e connected to the second sewage discharge channel 274e. The second sewage discharge interface 212e is located at the top of the sewage storage box 202e. The first sewage discharge interface 108e docks with the second sewage discharge interface 212e as the sewage storage box 202e is installed on the host 100e, so that the first sewage discharge channel 110e is connected to the second sewage discharge channel 274e.

[0424] Specifically, in Fig.65 , Fig.68In the illustrated embodiment, the main machine 100e forms a columnar protrusion at the first sewage discharge interface 108e, and the sewage storage box 202e forms a columnar depression at the second sewage discharge interface 212e. When the sewage storage box 202e is installed on the main machine 100e, the columnar protrusion is inserted into the columnar depression, so that the first sewage discharge interface 108e and the second sewage discharge interface 212e are arranged opposite to each other and connected. In order to improve the sealing performance, a sealing object can be set between the matching surface of the columnar protrusion and the sewage storage box 202e.

[0425] In other embodiments, a columnar depression is formed at the first sewage discharge interface 108e of the main machine 100e, and a columnar protrusion is formed at the second sewage discharge interface 212e of the sewage storage tank 202e.

[0426] In other embodiments, the surface of the main machine 100e at the first sewage discharge interface 108e is flat, and the surface of the sewage storage box 202e at the second sewage discharge interface 212e is flat. A sealing object is provided at the joint of the main machine 100e and the sewage storage box 202e to improve the sealing effect.

[0427] When the user installs the dirt storage box 202e, there is no need for a separate action to connect the first drain channel 110e and the second drain channel 274e. Similarly, when the user removes the dirt storage box 202e, there is no need for a separate action to disconnect the first drain channel 110e and the second drain channel 274e. This arrangement reduces the user's operating steps and further improves the convenience of cleaning the dirt storage box 202e.

[0428] exist Fig.65 , Fig.68 In the illustrated embodiment, both the first sewage discharge interface 108e and the second sewage discharge interface 212e are open. In other embodiments, the first sewage discharge interface 108e and the second sewage discharge interface 212e may be joints with valves. In the process of installing the sewage storage tank 202e on the host 100e, the first sewage discharge interface 108e and the second sewage discharge interface 212e can be automatically connected and conducted. In the process of separating the sewage storage tank 202e from the host 100e, the first sewage discharge interface 108e and the second sewage discharge interface 212e can be separated, and after separation, the first sewage discharge interface 108e closes the first sewage discharge channel 110e, and the second sewage discharge interface 212e closes the second sewage discharge channel 274e.

[0429] The above embodiments describe that the dirt in the dirt storage chamber 208e can be discharged through the second dirt discharge channel 274e and the first dirt discharge channel 110e in sequence. The following describes in detail how to collect the dirt generated during the cleaning process of the host 100e into the dirt storage chamber 208e.

[0430] Please continue reading Fig.64 , Fig.65 as well as Fig.68In some embodiments, when the dirt storage component 200e is installed on the main unit 100e, the main unit 100e cooperates with the dirt storage component 200e to form a negative pressure environment in the dirt storage chamber 208e, so that the dirt generated during the cleaning process of the main unit 100e enters the dirt storage chamber 208e through the first dirt inlet channel 122e and the second dirt inlet channel 278e in sequence.

[0431] Specifically, the host 100e also has a first sewage inlet channel 122e. The sewage storage box 202e also has a second sewage inlet channel 278e connected to the sewage storage chamber 208e. The second sewage inlet channel 278e is used to connect with the first sewage inlet channel 122e when the sewage storage box 202e is installed on the host 100e. When the sewage storage chamber 208e forms a negative pressure environment, the dirt at the host 100e enters the sewage storage chamber 208e through the first sewage inlet channel 122e and the second sewage inlet channel 278e in sequence.

[0432] In some embodiments, the host 100e has a cleaning component 124e, and the cleaning component 124e includes a water outlet mechanism (not shown) and a floor-scrubbing roller brush (not shown). The water outlet mechanism sprays water to the floor-scrubbing roller brush, and the wet floor-scrubbing roller brush scrubs the floor. The host 100e has a sewage extraction port (not shown), which is connected to the first sewage inlet channel 122e. The sewage extraction port is open. The sewage extraction port is set corresponding to the cleaning component 124e, and sucks the dirt generated by scrubbing the floor-scrubbing roller brush.

[0433] In one embodiment of the present disclosure, the host 100e further comprises a first sewage inlet interface 120e connected to the first sewage inlet channel 122e. The sewage storage tank 202e further comprises a second sewage inlet interface 230e connected to the second sewage inlet channel 278e. The second sewage inlet interface 230e is located at the top of the sewage storage tank 202e. The first sewage inlet interface 120e docks with the second sewage inlet interface 230e as the sewage storage tank 202e is installed on the host 100e, so that the first sewage inlet channel 122e is connected to the second sewage inlet channel 278e.

[0434] The specific structure of the connection between the first sewage inlet interface 120e and the second sewage inlet interface 230e can refer to the specific structure of the connection between the first sewage discharge interface 108e and the second sewage discharge interface 212e, which will not be repeated here.

[0435] As the dirt storage box 202e is installed on the main unit 100e, the first dirt inlet interface 120e and the second dirt inlet interface 230e can be automatically docked, which reduces the user's operation steps and further improves the convenience of cleaning the dirt storage box 202e.

[0436] Please also read Fig.71 , Fig.71 It is a top view of the dirt storage assembly in one embodiment of the cleaning device disclosed herein, with the box cover omitted.

[0437] In some embodiments, the dirt storage box 202e has a liquid inlet 250e. The second dirt inlet channel 278e is connected to the dirt storage chamber 208e through the liquid inlet 250e. The liquid inlet 250e is located at the top of the dirt storage chamber 208e, so that the dirt in the second dirt inlet channel 278e enters the dirt storage chamber 208e from top to bottom. The dirt storage assembly 200e also includes a second filter element 252e, which is arranged in the dirt storage chamber 208e and is located below the liquid inlet 250e. The dirt flowing out of the liquid inlet 250e is filtered by the second filter element 252e, so that large particles in the dirt remain on the second filter element 252e. By arranging the second dirt inlet interface 230e at the top of the dirt storage box 202e, the length of the second dirt inlet channel 278e can be shortened, thereby simplifying the structure of the dirt storage box 202e.

[0438] Please continue reading Fig.64 , Fig.65 as well as Fig.68 In some embodiments, the host 100e can form a negative pressure environment in the dirt storage chamber 208e of the dirt storage component 200e.

[0439] Specifically, the host 100e also has a negative pressure device 118e and a first air flow channel 116e connected to each other. The dirt storage box 202e also has a second air flow channel 276e connected to the dirt storage chamber 208e. The second air flow channel 276e is used to connect to the first air flow channel 116e when the dirt storage box 202e is installed on the host 100e. The negative pressure device 118e is used to form a negative pressure environment in the dirt storage chamber 208e through the first air flow channel 116e and the second air flow channel 276e in sequence.

[0440] The negative pressure device 118e may be a fan or a negative pressure pump.

[0441] In other embodiments, the dirt storage assembly 200e itself can form a negative pressure environment in the dirt storage chamber 208e. For example, the negative pressure device 118e is disposed outside the dirt storage box 202e, and a battery is separately provided to power the negative pressure device 118e.

[0442] Compared with the waste storage component 200e itself forming a negative pressure environment in the waste storage chamber 208e, the scheme of forming a negative pressure environment in the waste storage chamber 208e through the host 100e can simplify the structure of the waste storage component 200e.

[0443] In some embodiments, the host 100e further comprises a first airflow interface 114e connected to the first airflow channel 116e. The dirt storage box 202e further comprises a second airflow interface 228e connected to the second airflow channel 276e. The second airflow interface 228e is located at the top of the dirt storage box 202e. The first airflow interface 114e docks with the second airflow interface 228e as the dirt storage box 202e is installed on the host 100e, so that the first airflow channel 116e is connected to the second airflow channel 276e.

[0444] The specific structure of the connection between the first airflow interface 114e and the second airflow interface 228e can refer to the specific structure of the connection between the first sewage discharge interface 108e and the second sewage discharge interface 212e, which will not be repeated here.

[0445] As the dirt storage box 202e is installed on the main unit 100e, the first airflow interface 114e and the second airflow interface 228e can be automatically connected, which reduces the user's operation steps and further improves the convenience of cleaning the dirt storage box 202e.

[0446] When the dirt storage chamber 208e needs to form a negative pressure environment, the dirt storage box 202e has a suction port 238e, which is connected to the second air flow channel 276e and is open in the dirt storage chamber 208e (see FIG. Fig.72 The suction port 238e needs to be located at the top of the dirt storage box 202e to prevent dirt in the dirt storage cavity 208e from entering the suction port 238e. The second airflow interface 228e is arranged at the top of the dirt storage box 202e, which can shorten the length of the second airflow channel 276e and simplify the structure of the dirt storage box 202e.

[0447] For the convenience of cleaning the dirt storage chamber 208e of the dirt storage box 202e, it is also necessary to open the dirt storage chamber 208e more conveniently. For this reason, the following improvements are also made.

[0448] See also Fig.70 . Fig.70 It is a cross-sectional schematic diagram of the connection between the box cover and the box body in one embodiment of the cleaning device disclosed in the present invention.

[0449] In some embodiments, the dirt storage tank 202e includes a tank body 210e and a tank cover 206e.

[0450] The box body 210e has a dirt storage chamber 208e inside. One end of the dirt storage chamber 208e has a second opening 272e. The inner wall surface of the box body 210e is provided with a limiting groove 264e.

[0451] The box cover 206e includes a cover body 266e, a plug connector 268e and an elastic member 270e. The cover body 266e is detachably connected to the opening 272e of the box body 210e and covers the opening 272e. The plug connector 268e is movably arranged on the cover body 266e. The plug connector 268e can be movably switched between a first position and a second position. When the plug connector 268e is in the first position, the plug connector 268e is inserted in the limiting groove 264e so that the cover body 266e covers the second opening 272e. When the plug connector 268e is in the second position, the plug connector 268e is disengaged from the limiting groove 264e to allow the cover body 266e to open the second opening 272e. The elastic member 270e is connected to the plug connector 268e and the cover body 266e respectively. The elastic member 270e acts on the connector 268e and resets the connector 268e from the second position to the first position. Specifically, the elastic member 270e is used to apply an elastic force to the connector 268e so that the connector 268e is in the first position, and the connector 268e can overcome the elastic force under the action of external force and be in the second position.

[0452] Specifically, in Fig.70 In the illustrated embodiment, a portion of the cover body 266e is embedded in the second opening 272e of the box body 210e. The plug-in connector 268e is slidably matched with the cover body 266e in the horizontal direction. The number of the plug-in connector 268e is two. The two plug-in connectors 268e can be brought close to or separated from each other in the horizontal direction. The elastic member 270e can optionally be a spring. The number of the elastic member 270e is two. The elastic member 270e corresponds to the plug-in connector 268e one by one. One end of the elastic member 270e in the horizontal direction elastically abuts against the corresponding plug-in connector 268e, and the other end elastically abuts against the cover body 266e. The number of the limiting grooves 264e is two. The limiting grooves 264e correspond to the plug-in connector 268e one by one. When the plug-in connector 268e is in the first position, it is inserted in the corresponding limiting groove 264e. When the plug-in connector 268e is in the second position, it can be disengaged from the corresponding limiting groove 264e.

[0453] When it is necessary to open the box cover 206e, the user drives the two connectors 268e to move closer to each other, so that the connectors 268e are disengaged from the corresponding limiting grooves 264e, and then the user pulls out the box cover 206e.

[0454] When the second opening 272e needs to be covered, the user drives the two connectors 268e to move closer to each other, inserts the box cover 206e into the second opening 272e of the box body 210e, and then releases the two connectors 268e. The elastic member 270e drives the connector 268e to be inserted into the limiting groove 264e, so that the position of the box cover 206e is fixed.

[0455] When the dirt storage chamber 208e needs to form a negative pressure environment, the sealing performance of the dirt storage box 202e needs to be ensured. To this end, the following improvements are also made.

[0456] In some embodiments, the box cover 206e further includes a sealing strip 294e. The cover body 266e has a second receiving groove 292e arranged in a full circle around the outer circumference. When the cover body 266e covers the second opening 272e, the second receiving groove 292e is arranged relative to the inner wall surface of the box body 210e. The sealing strip 294e is accommodated in the second receiving groove 292e and is arranged in a full circle around the outer circumference of the cover body 266e. The sealing strip 294e is elastic. When the cover body 266e covers the second opening 272e, the sealing strip 294e is sandwiched between the cover body 266e and the box body 210e, thereby improving the sealing performance. The sealing strip 294e can be made of rubber material.

[0457] In some embodiments, the cover body 266e includes a lower cover 296e and an upper cover 298e. The lower cover 296e and the upper cover 298e are split structures. The lower cover 296e is embedded in the second opening 272e of the box body 210e. The upper cover 298e covers the end surface of the box body 210e at the second opening 272e. A cavity is formed between the lower cover 296e and the upper cover 298e to install the plug-in 268e and the elastic member 270e.

[0458] See also Fig.71 and Fig.72 , Fig.71 1 is a top view of a dirt storage assembly in an embodiment of the cleaning device disclosed herein, omitting the box cover. Fig.72 It is a schematic diagram of the cross-sectional structure of a dirt storage component in one embodiment of the cleaning device disclosed herein, showing only a portion thereof.

[0459] In some embodiments, the dirt storage box 202e also has a suction port 238e connected to the dirt storage chamber 208e, and a negative pressure environment is created in the dirt storage chamber 208e through the suction port 238e. The suction port 238e is open in the dirt storage chamber 208e, and the air in the dirt storage chamber 208e can be discharged through the suction port 238e, so that the dirt storage chamber 208e forms a negative pressure environment. Specifically, in some embodiments, the second air flow channel 276e is connected to the dirt storage chamber 208e through the suction port 238e. The negative pressure device 118e sucks the air of the dirt storage chamber 208e through the first air flow channel 116e, the second air flow channel 276e, and the suction port 238e in sequence. In some other embodiments, the negative pressure device 118e is disposed in the dirt storage box 202e, and sucks the air of the dirt storage chamber 208e through the suction port 238e.

[0460] The dirt storage assembly 200e also includes a cover 232e. The cover 232e includes a rotating portion 235e, a floating portion 234e, and a cover 236e. The rotating portion 235e is rotatably disposed in the dirt storage chamber 208e. The floating portion 234e and the cover 236e are respectively located on opposite sides of the rotating portion 235e. The density of the floating portion 234e is less than the density of dirt. The floating portion 234e can rotate around the rotation axis L2e of the rotating portion 235e (along the D1e direction) under the action of buoyancy, so that the cover 236e covers the suction port 238e. The floating portion 234e can also rotate in the opposite direction around the rotation axis L2e (along the D2e direction) under the action of its own gravity, so that the cover 236e opens the suction port 238e.

[0461] Specifically, when the cleaning device 10e is in use, the rotation axis L2e is a horizontal line. A cavity may be provided inside the floating portion 234e.

[0462] During the movement of the cleaning device 10e, dirt in the dirt storage chamber 208e may sway, and the dirt may enter the negative pressure device 118e through the suction port 238e and affect the operation of the negative pressure device 118e. By providing the cover 232e, during the normal use of the cleaning device 10e, the suction port 238e is in an open state. When the dirt in the dirt storage chamber 208e sways, the cover 232e covers the suction port 238e, reducing the probability of dirt entering the suction port 238e.

[0463] Only the floating portion 234e of the covering member 232e is in contact with dirt, and the rotational connection between the rotating portion 235e and the dirt storage box 202e is not in contact with dirt, thereby reducing the probability of the rotational connection being stuck.

[0464] In order to improve the effect of the covering portion 236e covering the suction port 238e, in some embodiments, the covering portion 236e flexibly abuts against the edge of the dirt storage box 202e at the suction port 238e. Specifically, the dirt storage assembly 200e also includes a sealing member 240e. The sealing member 240e is arranged on the dirt storage box 202e and / or the covering portion 236e. The sealing member 240e is elastic. The sealing member 240e is used to seal the gap between the covering portion 236e and the dirt storage box 202e at the suction port 238e.

[0465] The sealing member 240e can be made of rubber. Fig.70In the illustrated embodiment, the sealing member 240e is disposed around the edge of the dirt storage box 202e at the suction port 238e in a complete circle, and covers the edge of the dirt storage box 202e at the suction port 238e. When the cover portion 236e covers the suction port 238e, the sealing member 240e is sandwiched between the dirt storage box 202e and the cover portion 236e, filling the gap between the dirt storage box 202e and the cover portion 236e. In other embodiments, the sealing member 240e may be disposed on the side of the cover portion 236e facing the suction port 238e.

[0466] A liquid level detection device is usually provided in the dirt storage box 202e of the cleaning device 10e to remind the user to discharge the dirt in the dirt storage box 202e in time. In the related art, the liquid level detection device is provided in the dirt storage box 202e and is electrically connected to the host 100e. In the case where the dirt storage box 202e is detachable from the host 100e, the structure of the liquid level detection device needs to be improved to adapt to the solution that the dirt storage box 202e is detachable. The details are as follows.

[0467] See also Fig.73 , Fig.73 It is a schematic diagram of the cross-sectional structure of the dirt storage assembly in one embodiment of the cleaning device disclosed herein, with the box cover omitted.

[0468] In some embodiments, the dirt storage assembly 200e further includes a detection member 242e. The detection member 242e is movably disposed in the dirt storage chamber 208e. The detection member 242e can move under the buoyancy provided by the dirt. The host 100e further includes a sensor 244e. The sensor 244e is used to detect the liquid level of the dirt by sensing the movement of the detection member 242e. When the dirt storage tank 202e is installed on the host 100e, the sensor 244e is located outside the dirt storage tank 202e.

[0469] The detection member 242e is physically separated from the sensor 244e. When the dirt storage component 200e is separated from the host 100e, the detection member 242e is separated from the sensor 244e. When the dirt storage component 200e is installed on the host 100e, the detection member 242e and the sensor 244e restore the predetermined relative position relationship. Therefore, the detection member 242e and the sensor 244e can adapt to the solution that the dirt storage component 200e can be separated to perform liquid level detection.

[0470] In some embodiments, the dirt storage assembly 200e further includes a guide rod 246e. The guide rod 246e extends vertically and is disposed in the dirt storage chamber 208e. The detection member 242e includes a float 260e and a magnet 262e. The float 260e is movably disposed on the guide rod 246e, wherein the density of the float 260e is less than the density of the dirt. The magnet 262e is disposed on the float 260e, and the float 260e is used to drive the magnet 262e to move vertically. The sensor 244e is a Hall sensor.

[0471] Specifically, the detection member 242e is slidably matched with the guide rod 246e to move in the vertical direction, and the detection member 242e cannot be around the guide rod 246e to avoid uncontrollable magnetic field direction. More specifically, the guide rod 246e is provided with a guide groove 267e, and the guide groove 267e extends in the vertical direction. The float 260e is clamped in the guide groove 267e and slidably matched with the guide rod 246e.

[0472] Specifically, the detection member 242e can reciprocate between a first height and a second height in the vertical direction. The first height is higher than the second height. The detection member 242e descends from the first height to the second height under the action of its own gravity, and can rise from the second height to the second height under the action of buoyancy. More specifically, the dirt storage assembly 200e also includes a first limiting portion 263e and a second limiting portion 265e. The first limiting portion 263e and the second limiting portion 265e are respectively fixedly disposed on the guide rod 246e and are arranged at intervals in the vertical direction. The detection member 242e is located between the first limiting portion 263e and the second limiting portion 265e. When the detection member 242e abuts against the first limiting portion 263e, it is at the first height. When the detection member 242e abuts against the second limiting portion 265e, it is at the second height.

[0473] The first limiting portion 263e and the second limiting portion 265e may be a retaining spring. After the detection member 242e is assembled on the guide rod 246e, the first limiting portion 263e and the second limiting portion 265e are installed on the guide rod 246e.

[0474] Specifically, the sensor 244e is set corresponding to the first height. When the detection member 242e is at the first height, it is set horizontally opposite to the sensor 244e and triggers the sensor 244e. When the detection member 242e is at the second height, the detection member 242e and the sensor 244e are misaligned and the sensor 244e is not triggered.

[0475] When the dirty liquid level is low, the detection member 242e is carried on the second limit portion 265e under the action of gravity. At this time, the detection member 242e is at the second height, and the sensor 244e is not triggered. As the dirty liquid level rises, the detection member 242e rises under the action of buoyancy until the detection member 242e abuts against the first limit portion 263e. At this time, the detection member 242e is at the first height, and the sensor 244e is triggered. After the sensor 244e is triggered, the corresponding light can prompt the user of the current liquid level.

[0476] In some embodiments, the number of the detection element 242e is multiple ( Fig.73There are three of them, and each detection member 242e is arranged in sequence along the vertical direction. There are multiple sensors 244e, and each sensor 244e is arranged in sequence along the vertical direction, and the sensors 244e correspond to the detection members 242e one by one. When the detection member 242e moves to be arranged opposite to the corresponding sensor 244e, the corresponding sensor 244e senses that the dirty liquid level reaches the liquid level represented by the corresponding sensor 244e.

[0477] Fig.73 In the illustrated embodiment, the three sensors 244e from top to bottom represent the high liquid level, the middle liquid level and the low liquid level respectively. When the bottom sensor 244e is triggered, the dirt is at the low liquid level. When the middle sensor 244e is triggered, the dirt is at the middle liquid level. When the top sensor 244e is triggered, the dirt is at the high liquid level.

[0478] With such an arrangement, different liquid levels of the dirt in the dirt storage box 202e can be detected respectively.

[0479] See also Fig.74 , Fig.74 It is a schematic diagram of the cross-sectional structure of the dirt storage assembly in one embodiment of the cleaning device disclosed herein, with the box cover omitted.

[0480] The structure of the sensor 244e may also be appropriately deformed.

[0481] In some embodiments, the sensor 244e has a plurality of sensing portions 280e ( Fig.74 The sensing parts 280e are arranged in sequence in the vertical direction. The sensing parts 280e correspond to the detection members 242e one by one. When the detection member 242e moves to be arranged opposite to the corresponding sensing part 280e, the sensor 244e senses that the dirty liquid level reaches the liquid level represented by the sensing part 280e corresponding to the detection member 242e.

[0482] In the above embodiment, the sensor 244e and the detection member 242e are detected by the Hall principle. In other embodiments, the sensor 244e can also be triggered by other means. For example, the sensor 244e identifies the movement of the detection member 242e by visual detection. When the detection member 242e moves, the sensor 244e is triggered.

[0483] See also Figure 62 to Figure 64. One embodiment of the present disclosure also provides a dirt storage assembly 200e of a cleaning device 10e. The cleaning device 10e also includes a main body 100e, and the main body 100e has a first dirt discharge channel 110e. The dirt storage assembly 200e includes a dirt storage tank 202e and a dirt discharge pump 214e. The dirt storage tank 202e can be detachably installed on the main body 100e. The dirt storage tank 202e has a dirt storage chamber 208e and a second dirt discharge channel 274e that are connected to each other. The dirt storage chamber 208e is used to store recycled dirt. The second dirt discharge channel 274e is used to be connected to the first dirt discharge channel 110e when the dirt storage tank 202e is installed on the main body 100e. The dirt discharge pump 214e is disposed in the dirt storage tank 202e. The dirt discharge pump 214e is connected to the second dirt discharge channel 274e. The sewage pump 214e is used to drive the dirt in the sewage storage chamber 208e to be discharged through the second sewage discharge channel 274e and the first sewage discharge channel 110e in sequence.

[0484] The dirt storage assembly 200e has been described in detail in the above-mentioned embodiments of the cleaning device 10e. The dirt storage assembly 200e can be understood by referring to the above-mentioned embodiments of the cleaning device 10e, and will not be described in detail here.

[0485] See also Figure 62 to Figure 64 . An embodiment of the present disclosure also provides a main unit 100e of a cleaning device 10e. The cleaning device 10e also includes a dirt storage component 200e. The dirt storage component 200e includes a dirt storage box 202e and a dirt discharge pump 214e. The dirt storage box 202e has a dirt storage chamber 208e and a second dirt discharge channel 274e that are connected to each other. The dirt discharge pump 214e is disposed in the dirt storage box 202e, and the dirt discharge pump 214e is connected to the second dirt discharge channel 274e. The main unit 100e is detachably mounted for the dirt storage box 202e. The dirt storage chamber 208e is used to store recovered dirt. The main unit 100e has a first dirt discharge channel 110e. The first sewage discharge channel 110e is used to connect with the second sewage discharge channel 274e when the sewage storage box 202e is installed on the main unit 100e, so that the sewage pump 214e drives the dirt in the sewage storage chamber 208e to be discharged through the second sewage discharge channel 274e and the first sewage discharge channel 110e in sequence.

[0486] The host 100e has been introduced in detail in the above-mentioned embodiments of the cleaning device 10e. The host 100e can be understood by referring to the above-mentioned embodiments of the cleaning device 10e, and will not be described in detail here.

[0487] The technical solution provided by the embodiment of the present disclosure is described below in conjunction with specific application scenarios.

[0488] Application scenario 1:

[0489] See also Fig.62 and Fig.63. The cleaning device 10e is a commercial floor scrubber. Compared with a household floor scrubber, the volume of the dirt storage chamber 208e of the commercial floor scrubber is larger, for example, 10eL. The cleaning device 10e includes a main unit 100e and a dirt storage component 200e. The main unit 100e can move autonomously along the planned path and clean the floor. The main unit 100e includes a first cleaning component and a second cleaning component. The first cleaning component absorbs and collects dust and dirt into the dust box through suction force. The second cleaning component mops the floor and recycles the sewage on the floor into the dirt storage component 200e through suction force. When the sewage in the sewage storage component 200e reaches a predetermined liquid level, the main unit 100e moves to the base station and docks with the base station, so that the sewage in the sewage storage component 200e is discharged to the base station through the main unit 100e. After discharging the sewage, the main unit 100e continues to move automatically along the planned path and clean the floor. After the cleaning device 10e completes the cleaning work, the user removes the dirt storage assembly 200e from the main unit 100e, cleans the dirt storage cavity 208e, and then installs the dirt storage assembly 200e on the main unit 100e.

[0490] Application scenario 2:

[0491] See also Fig.62 and Fig.63 The cleaning device 10e includes a main body 100e and a plurality of dirt storage components 200e ( Fig.62 and Fig.63 (in the figure, one is one). Each dirt storage assembly 200e can be detachably mounted on the main unit 100e. One dirt storage assembly 200e is mounted on the main unit 100e, and the remaining dirt storage assemblies 200e are used as spares. When the dirt in the dirt storage assembly 200e reaches a predetermined liquid level, the spare dirt storage assembly 200e is replaced with the main unit 100e, and the main unit 100e continues to perform cleaning work. The user pours out the dirt in the dirt storage assembly 200e removed from the main unit 100e. In this way, the time for the cleaning device 10e to discharge dirt is greatly shortened, which can improve the cleaning efficiency.

[0492] Application scenario three:

[0493] See also Figure 62 to Figure 64 The cleaning device 10e includes a main body 100e and a dirt storage component 200e.

[0494] The host 100e is used for cleaning, and has a first sewage discharge channel 110e, a first sewage inlet channel 122e, a first air flow channel 116e and a first conductive member 130e. The host 100e has a mounting cavity 104e, and the top of the mounting cavity 104e has a first opening 106e.

[0495] The dirt storage assembly 200e is accommodated in the installation cavity 104e and supported by the main unit 100e.

[0496] The sewage storage assembly 200e includes a sewage storage tank 202e, a valve 224e, a sewage pump 214e and a second conductive member 216e.

[0497] The sewage storage box 202e has a sewage storage chamber 208e and a second sewage discharge passage 274e, a second sewage inlet passage 278e and a second air flow passage 276e respectively connected to the sewage storage chamber 208e. A sewage pump 214e is disposed in the sewage storage box 202e. The sewage pump 214e is connected to the second sewage discharge passage 274e. A valve 224e is connected to the second sewage discharge passage 274e.

[0498] When the dirt storage assembly 200e is placed in the installation cavity 104e, the first drain channel 110e is automatically connected to the second drain channel 274e, the first inlet channel 122e is automatically connected to the second inlet channel 278e, the first air flow channel 116e is automatically connected to the second air flow channel 276e, and the first conductive member 130e is automatically connected to the second conductive member 216e. After the dirt storage assembly 200e is taken out of the installation cavity 104e, the first drain channel 110e is automatically disconnected from the second drain channel 274e, the first inlet channel 122e is automatically disconnected from the second inlet channel 278e, the first air flow channel 116e is automatically disconnected from the second air flow channel 276e, and the first conductive member 130e is automatically separated from the second conductive member 216e.

[0499] During the cleaning process of the cleaning device 10e, the main machine 100e sucks the air in the dirt storage chamber 208e through the first airflow channel 116e and the second airflow channel 276e in turn, so that the dirt storage chamber 208e forms a vacuum environment. The dirt storage box 202e sucks the dirt at the main machine 100e into the dirt storage chamber 208e through the first dirt inlet channel 122e and the second dirt inlet channel 278e in turn. When the dirt in the dirt storage chamber 208e reaches a predetermined liquid level, the main machine 100e controls the sewage pump 214e to start, and the sewage pump 214e pumps the dirt in the second sewage discharge channel 274e. The valve 224e opens the second sewage discharge channel 274e under pressure, so that the dirt in the sewage storage chamber 208e is discharged through the second sewage discharge channel 274e and the first sewage discharge channel 110e in turn. When the sewage pump 214e is not working, the valve 224e blocks the second sewage channel 274e, so that the sewage storage chamber 208e remains sealed.

[0500] When the dirt storage cavity 208e needs to be cleaned, the user pulls up the dirt storage assembly 200e to separate the dirt storage assembly 200e from the main unit 100e. After the user finishes cleaning the dirt storage assembly 200e, the user places the dirt storage assembly 200e in the installation cavity 104e through the first opening 106e.

[0501] Application scenario 4:

[0502] See also Fig.62 , Fig.63 as well as Fig.72 The cleaning device 10e includes a main unit 100e and a dirt storage component 200e. The main unit 100e is used for cleaning. The dirt storage component 200e includes a dirt storage box 202e. The dirt storage box 202e is used to be detachably mounted on the main unit 100e. The dirt storage box 202e has a dirt storage chamber 208e and a suction port 238e. The dirt storage chamber 208e is used to store dirt recovered by the main unit 100e. The main unit 100e sucks air in the dirt storage chamber 208e through the suction port 238e. The dirt storage component 200e also includes a covering member 232e. The covering member 232e is rotatably disposed in the dirt storage chamber 208e.

[0503] During the movement of the cleaning device 10e, the bulge on the ground causes the dirt in the dirt storage chamber 208e to sway, and the swaying dirt drives the cover 232e to rotate along the direction D1e, so that the cover 232e covers the suction port 238e. After the fluctuation of the liquid level decreases, the cover 232e rotates along the direction D2e, the cover 232e opens the suction port 238e, and the host 100e continues to suck air through the suction port 238e.

[0504] Application scenario five:

[0505] See also Fig.62 , Fig.63 as well as Fig.73 The cleaning device 10e includes a main unit 100e and a dirt storage component 200e. The main unit 100e is used for cleaning. The dirt storage component 200e includes a dirt storage box 202e. The dirt storage box 202e is used to be detachably mounted on the main unit 100e. The dirt storage box 202e has a dirt storage chamber 208e. The dirt storage chamber 208e is used to store dirt recovered by the main unit 100e.

[0506] The host 100e includes three sensors 244e, and the three sensors 244e are arranged at intervals in the vertical direction. The dirt storage component 200e includes three detection members 242e, and the three detection members 242e are located in the dirt storage chamber 208e and are arranged at intervals in the vertical direction. The detection member 242e is slidably fitted on the guide rod 246e and can move within a predetermined vertical range. The sensor 244e is a Hall sensor. The detection member 242e is magnetic. When there is no dirt in the dirt storage chamber 208e, the detection member 242e and the sensor 244e are misaligned. When the dirt in the dirt storage chamber 208e drives the lowest detection member 242e to move to face the lowest sensor 244e, the lowest sensor 244e is triggered, and the low water level light on the host 100e is lit. When the dirt in the dirt storage chamber 208e drives the middle detection member 242e to move to the middle sensor 244e, the middle sensor 244e is triggered, and the middle water level light on the host 100e is lit. When the dirt in the dirt storage chamber 208e drives the uppermost detection member 242e to move to the uppermost sensor 244e, the uppermost sensor 244e is triggered, and the high water level light on the host 100e is lit. When the high water level light is lit, the user pushes the cleaning device 10e to the sewage discharge location to discharge the dirt in the dirt storage chamber 208e.

[0507] When the dirt storage assembly 200e is separated from the main body 100e, the detection member 242e is separated from the sensor 244e. When the dirt storage assembly 200e is installed on the main body 100e, the detection member 242e and the sensor 244e return to the predetermined relative position.

[0508] In summary, the above-mentioned cleaning device, dirt storage assembly, and main engine embodiments improve the convenience of cleaning the dirt storage box. At the same time, the cleaning device can actively discharge dirt through the main engine, avoiding the active discharge problem caused by the detachable dirt storage box.

[0509] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
