Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a cleaning device. Background Art

[0002] At present, in order to ensure safety, during normal use of cleaning equipment such as floor scrubbers or vacuum cleaners, the body of the machine is in an upright state, which will put the floor brush in a dormant state. At this time, the floor brush cannot move forward for cleaning. This is because when the body and handle are both upright, it does not conform to ergonomics. If used forcibly, it is easy to cause the cleaning equipment to tip over. Therefore, it is usually tilted to a suitable height and then the equipment is lifted for cleaning.

[0003] In addition, most floor scrubbers are integrated with components such as clean water tanks, dirty water tanks and suction motors, which makes the floor scrubber body components heavy. If the user holds the handle of the machine for a long time to push it for cleaning, the user's arm needs to bear most of the weight of the entire machine, and cannot move back and forth and turn lightly, and is easily tired. Utility Model Content

[0004] In order to solve at least one of the problems mentioned in the background technology, the present application provides a cleaning device, which aims to solve the technical problem that the body of the floor scrubber in the related technology is integrated with components such as a clean water tank, a sewage tank and a suction motor, resulting in a large weight of the floor scrubber body assembly. If the user holds the handle of the body for a long time to push the cleaning, the user's arm needs to bear most of the weight of the entire body, and cannot move and rotate back and forth lightly, and is easily tired.

[0005] To achieve the above objectives, in a first aspect, the present application provides a cleaning device, comprising:

[0006] A floor brush assembly is provided with a cleaning member for cleaning the surface to be cleaned;

[0007] A body assembly is rotatably connected to an end of the floor brush assembly away from the cleaning member, and a center of gravity height of the body assembly relative to the floor brush assembly in an upright state is lower than 1 / 2 of its upright height;

[0008] A handle assembly, the handle assembly being rotatably connected to the body assembly;

[0009] A locking assembly, which is arranged on the body assembly or the handle assembly and is used to fix or release the handle assembly;

[0010] When the body assembly is kept upright relative to the floor brush assembly, the locking assembly releases the handle assembly so that the handle assembly can rotate in the opposite direction of the floor brush assembly.

[0011] In the cleaning device provided in the present application, the locking assembly releases the handle assembly so that the handle assembly can rotate relative to the body assembly. The handle assembly is rotatably connected to the body assembly, so that the user can rotate the handle assembly to a comfortable holding position for support according to his own habits while the body assembly remains in an upright state. In this way, the gravity of the body assembly basically acts on the floor brush assembly, and the handle assembly does not need to share the weight of the body assembly. In addition, the low center of gravity of the body assembly is set to reduce the torque of the body assembly, further ensuring the stability of the body assembly in an upright state. At this time, the user only needs to gently hold the handle assembly, which is very labor-saving; if the handle assembly and the body assembly of a traditional floor scrubber are fixedly designed as a whole and cannot rotate relative to each other, the body assembly will rotate relative to the floor brush assembly with the handle assembly. Compared with the upright state, the larger the rotation amplitude, the more gravity the handle assembly needs to share with the body assembly, which is very easy to fatigue and is not suitable for users with less strength.

[0012] To this end, the present solution also fixes the handle assembly through a locking assembly, so that the cleaning device of the present application has at least two usage modes, one is an ergonomic and labor-saving mode that can effectively save labor, and the other is a traditional mode in which the handle assembly and the body assembly are used as an integrated whole and the brush assembly rotates relative to each other. Users can choose according to their own needs and habits, which improves the convenience and efficiency of operation and can be compatible with the needs of different user groups.

[0013] In a second aspect, the present application provides a cleaning device, comprising:

[0014] A floor brush assembly is provided with a cleaning member for cleaning the surface to be cleaned;

[0015] A body assembly, rotatably connected to an end of the floor brush assembly away from the cleaning member;

[0016] A handle assembly, the handle assembly is rotatably connected to the back of the body assembly and can be rotated toward the back of the body assembly, and the back of the body assembly is opposite to the travel direction of the floor brush assembly;

[0017] A locking assembly, which is arranged on the body assembly or the handle assembly and is used to fix or release the handle assembly;

[0018] The cleaning device has a normal mode and a labor-saving mode;

[0019] In the normal mode, the handle assembly is relatively locked with the body assembly, and the angle between the extension direction of the handle assembly and the extension direction of the body assembly is [0°, 15°);

[0020] In the labor-saving mode, the body assembly is in an upright state, and the angle between the extension direction of the handle assembly and the extension direction of the body assembly is [15°, 90°).

[0021] The cleaning device provided by the present application is provided with a locking assembly, which releases the handle assembly so that the handle assembly can rotate relative to the body assembly. The cleaning device can realize switching between a normal mode and a labor-saving mode. In normal mode, the user will rotate the body assembly to a suitable height relative to the vertical direction. Since the handle assembly and the body assembly are relatively locked, the handle assembly will rotate backwards with the body assembly at this time. Since the handle assembly is on the back of the body assembly, the angle of the handle assembly relative to the vertical direction will be larger than that of the body assembly. Since the gravity of the body assembly itself is borne by the floor brush assembly and the handle assembly, the larger the angle of the body assembly relative to the vertical direction, the greater the supporting force borne by the handle assembly. Therefore, the angle of rotation of the body assembly by the user will not be too large. In addition, due to the height of the user's grip, the body assembly generally rotates about 30°-60° relative to the vertical direction, and the angle at which the user holds the handle relative to the vertical direction is about 30°-75°. Too large or too small an angle will cause the user's wrist to rotate too large and easily become sore. The angle between the handle assembly and the body assembly is set to 0°-15°, and the optimal angle is about 10°. At this time, the user can easily control the tilt of the body assembly to put the floor brush assembly in working condition to complete the cleaning work. In the labor-saving mode, the body assembly is in an upright position. After ergonomic design, the angle between the handle assembly and the body assembly needs to be 15° to 90° for users to grasp. The best angle is around 45°. If the angle is too small, the handle will be too high, requiring users to keep their arms raised, which can easily cause arm fatigue. If the angle is too large, the handle will be too low, requiring users to bend over to carry it by hand, which can easily cause waist fatigue and make it impossible to use it for a long time. By setting the rotation angle, the user's labor intensity can be reduced, making cleaning work easier and more labor-saving.

[0022] In the above-mentioned cleaning device, optionally, a projection of the center of gravity of the body assembly in an upright state relative to the floor brush assembly within the plane where the floor brush assembly is located is located in a middle area of ​​the floor brush assembly.

[0023] Through the above configuration, the projection of the center of gravity of the fuselage assembly falls inside the floor brush assembly, so that the pressure of the fuselage assembly on the floor brush assembly can be borne entirely by the ground, and it has higher stability; if the projection of the center of gravity of the fuselage assembly falls outside the floor brush assembly, it is easy to be like a seesaw, and the downward force of the floor brush assembly is not enough to offset the gravity of the fuselage assembly, causing the equipment to tip over.

[0024] In the above-mentioned cleaning device, optionally, the connection point between the handle assembly and the body assembly is higher than the center of gravity of the body assembly.

[0025] Through the above-mentioned setting, when the connection point is higher than the center of gravity of the body assembly, the center of gravity of the cleaning equipment is more stable during operation, reducing the instability and shaking caused by the shift of the center of gravity, and improving the safety and stability of operation; in addition, it can reduce the labor intensity of the user during operation, making the cleaning work easier and more efficient, thereby facilitating the user to achieve more stable operation and control.

[0123] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0124] In the normal use of cleaning equipment such as floor scrubbers or vacuum cleaners in the related art, in order to ensure safety, the body of the floor scrubber or vacuum cleaner is in an upright state, which will put the floor brush in a dormant state. At this time, the floor brush cannot move forward for cleaning, because when the body and handle are both upright, it does not conform to human mechanics. If it is used forcibly, it is easy to cause the cleaning equipment to fall over, so it is usually tilted to a suitable height and then the equipment is lifted for cleaning. In addition, most floor scrubbers are integrated with components such as a clean water tank, a sewage tank, and a suction motor, resulting in a large weight of the floor scrubber body assembly. If the user holds the handle of the body for a long time to push the cleaning, the user's arm needs to bear most of the weight of the entire body, and cannot move back and forth and turn lightly, and is easy to feel tired. It should be noted that the body assembly is in an upright state, which is not limited to the body assembly being roughly upright on the floor brush assembly, but also includes the situation where the body assembly is stably sitting on the floor brush assembly. In the upright state, the angle between the body assembly and the floor brush assembly can be a range value, such as 75° to 105°.

[0125] Based on the above technical problems, the present application embodiment provides a cleaning device, see Figure 1 , including a floor brush assembly, a body assembly, a handle assembly and a locking assembly. The front end of the floor brush assembly is provided with a cleaning member for cleaning the surface to be cleaned, and the cleaning member is a roller brush or a wiping disc; the body assembly is rotatably connected to the rear end of the floor brush assembly away from the cleaning member, and the center of gravity height of the body assembly relative to the floor brush assembly in an upright state is lower than 1 / 2 of its upright height, and a lower center of gravity position is set so that the body assembly can sit firmly on the floor brush assembly; the handle assembly is rotatably connected to the body assembly; the locking assembly is set on the body assembly or the handle assembly, and is used to fix or release the body assembly; when the locking assembly releases the handle assembly, the handle assembly can be rotated in the opposite direction of the floor brush assembly when the body assembly is in an upright state. It should be noted that the travel direction of the floor brush assembly is the direction in which the device is pushed, toward the surface to be cleaned, that is, see Figure 2 The left direction of the device is the opposite direction of the device being pulled back, that is, see Figure 2 The right side direction, user side also refers to Figure 2 In the middle right direction, the user can conveniently hold the handle assembly for use on the back side of the body assembly.

[0126] In the cleaning device provided by the embodiment of the present application, the locking assembly releases the handle assembly so that the handle assembly can rotate relative to the body assembly. The handle assembly is rotatably connected to the body assembly, so that the user can rotate the handle assembly to a comfortable holding position for support according to their own habits while the body assembly remains upright. In this way, the gravity of the body assembly basically acts on the floor brush assembly, and the handle assembly does not need to share the weight of the body assembly. The user only needs to hold the handle assembly, which is very labor-saving; if the handle assembly and the body assembly of a traditional floor scrubber are fixedly designed as a whole and cannot rotate relative to each other, the body assembly will rotate relative to the floor brush assembly with the handle assembly. Compared with the upright state, the larger the rotation range, the more gravity the handle assembly needs to share with the body assembly, which is very easy to fatigue and is not suitable for users with less strength.

[0127] To this end, the present solution also fixes the handle assembly through a locking assembly, so that the cleaning device of the present application has at least two usage modes, one is an ergonomic and labor-saving mode that can effectively save labor, and the other is a traditional mode in which the handle assembly and the body assembly are used as an integrated whole and the brush assembly rotates relative to each other. Users can choose according to their own needs and habits, which improves the convenience and efficiency of operation and can be compatible with the needs of different user groups.

[0128] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar devices or devices with the same or similar functions. The described embodiments are embodiments of a part of the device of the present application, rather than embodiments of the entire device. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0129] Reference Figure 1-Figure 9 As shown, in a first aspect, an embodiment of the present application provides a cleaning device 10 , including a floor brush assembly 100 , a body assembly 200 , a handle assembly 300 and a locking assembly 400 .

[0130] The floor brush assembly 100 is used to clean the surface to be cleaned. The surface to be cleaned can be a floor or wall with different degrees of roughness, or a carpet or blanket with different lengths or types, or the surface of an object to be cleaned. The present application does not specifically limit the type of the surface to be cleaned.

[0131] The body assembly 200 is rotatably connected to the floor brush assembly 100. The locking assembly 400 is used to fix or release the handle assembly. The locking assembly 400 releases the handle assembly 300, which means that the locking assembly 400 enables the handle assembly 300 to rotate relative to the body assembly 200. The locking assembly 400 fixes the handle assembly 300, which means that the position between the body assembly 200 and the handle assembly 300 is locked.

[0132] In some embodiments, the locking assembly 400 is disposed on the body assembly 200 to fix or release the handle assembly 300. In other embodiments, the locking assembly 400 may also be disposed on the handle assembly 300.

[0133] It is understandable that the locking assembly 400 is disposed on the body assembly 200, that is, the locking assembly 400 is fixed to the body assembly 200, and the locking assembly 400 is used to connect the handle assembly 300. Since the body assembly 200 is heavy, the locking assembly 400 has high stability, and the structure of the cleaning device 10 is firm and stable, which can provide good structural stability.

[0134] When the locking assembly 400 releases the handle assembly 300, the handle assembly 300 can be rotated toward the user side when the body assembly 200 is in an upright state. The user can easily control the direction and angle of the cleaning device 10 to improve the convenience and flexibility of operation.

[0135] It should be noted that the upright state may mean that the length extension direction of the fuselage assembly 200 is the vertical direction, or is inclined at a small angle to the vertical direction. Among them, the small angle inclined to the vertical direction may mean an inclination of 0° to 1°, or an inclination of 1° to 2°, or an inclination of 2° to 3°, 3° to 5°, 4° to 8°, 5° to 10°, 8° to 15°, 10° to 15°, etc.

[0136] It can be understood that when the body assembly 200 is in an upright state, the connecting rod 320 rotates relatively away from the body assembly 200, that is, the distance between the handle assembly 300 and the body assembly 200 is large. At this time, the gravity of the heavier body assembly 200 and the floor brush assembly 100 acts on the surface to be cleaned, and the user's arm or wrist only needs to support the handle assembly 300 to push or pull the body assembly 200.

[0137] When a user uses the cleaning device 10, the user's wrist can maintain a natural posture, reducing discomfort in the hand or wrist and improving the comfort of operation.

[0138] In the cleaning device 10 provided in the embodiment of the present application, the handle assembly 300 is rotatably connected to the body assembly 200, so that the user can rotate the handle assembly 300 to a comfortable holding position for support according to his own habits while the body assembly 200 remains in an upright state. In this way, the gravity of the body assembly 200 basically acts on the floor brush assembly 100, and the handle assembly 300 does not need to share the weight of the body assembly 200. The user only needs to hold the handle assembly 300, which is very labor-saving; if the handle assembly and the body assembly of a traditional floor scrubber are designed to be fixed as a whole and cannot rotate relative to each other, the body assembly will rotate relative to the floor brush assembly along with the handle assembly. Compared with the upright state, the greater the rotation amplitude, the more the handle assembly needs to share the gravity of the body assembly, which is very easy to get tired and is not suitable for users with less strength.

[0139] To this end, the embodiment of the present application also fixes the handle assembly 300 through the locking assembly 400, so that the cleaning device 10 of the embodiment of the present application has at least two usage modes, one is an ergonomic and labor-saving mode that can effectively save labor, and the other is a traditional mode in which the handle assembly 300 and the body assembly 200 are used as a whole and the brush assembly 100 rotates relative to the ground. Users can choose according to their own needs and habits, which improves the convenience and efficiency of operation and can be compatible with the needs of different user groups.

[0140] Reference Figure 1-Figure 9 As shown, in a second aspect, an embodiment of the present application further provides a cleaning device 10 , including a floor brush assembly 100 , a body assembly 200 , a handle assembly 300 and a locking assembly 400 .

[0141] It is understandable that the relevant contents of the floor brush assembly 100, the body assembly 200, the handle assembly 300 and the locking assembly 400 have been described above and will not be repeated here.

[0142] The cleaning device 10 has a normal mode and a labor saving mode;

[0143] In the normal mode, the connecting rod 320 is relatively locked with the fuselage assembly 200, that is, the relative position of the connecting rod 320 and the fuselage assembly 200 remains unchanged. The angle between the extending direction of the connecting rod 320 and the extending direction of the fuselage assembly 200 is [0°, 15°).

[0144] It can be understood that the specific angle between the extension direction of the connecting rod 320 and the extension direction of the fuselage assembly 200 can be 0°~1°, 1°~2°, 2°~3°, 3°~5°, 4°~8°, 5°~10°, 8°~15°, 10°~15°, etc.

[0145] When the cleaning device 10 is in normal mode, the connecting rod 320 is relatively close to the body assembly 200, that is, the distance between the handle assembly 300 and the body assembly 200 is small. At this time, if the user uses the cleaning device 10 to complete the cleaning work, the cleaning device 10 is prone to tipping over. Therefore, in normal mode, the floor brush assembly 100 may not work.

[0146] In the labor-saving mode, the fuselage assembly 200 is in an upright state, that is, the length extension direction of the fuselage assembly 200 is in the vertical direction, or is inclined at a small angle to the vertical direction. At this time, the angle between the extension direction of the connecting rod 320 and the extension direction of the fuselage assembly 200 is [15°, 90°).

[0147] When the cleaning device 10 is in the labor-saving mode, the connecting rod 320 is relatively far away from the body assembly 200, that is, the distance between the handle assembly 300 and the body assembly 200 is large. At this time, the gravity of the heavier body assembly 200 and the floor brush assembly 100 acts on the surface to be cleaned, and the user's arm or wrist only needs to support the handle assembly 300 to push or pull the body assembly 200, which is the labor-saving mode.

[0148] The cleaning device 10 provided in the embodiment of the present application can switch between the normal mode and the labor-saving mode by setting the locking assembly 400. In the normal mode, the handle assembly 300 is relatively locked with the body assembly 200, and the angle between the handle assembly 300 and the body assembly 200 is small. The user can easily control the inclination of the body assembly 200 to put the floor brush assembly 100 in a working state to complete the cleaning work. In the labor-saving mode, the body assembly 200 is in an upright state, and the angle between the handle assembly 300 and the body assembly 200 is large, which can reduce the labor intensity of the user and make the cleaning work easier and more labor-saving.

[0149] Reference Figure 1-Figure 9 As shown, in a third aspect, the present application provides a cleaning device 10 , including a floor brush assembly 100 , a body assembly 200 and a handle assembly 300 .

[0150] It is understandable that the relevant contents of the floor brush assembly 100, the body assembly 200 and the handle assembly 300 have been described above and will not be repeated here.

[0151] The first sensing component is configured to detect that the body component 200 is in an upright state and trigger output of a first signal.

[0152] It can be understood that when the body assembly 200 is in an upright state, the handle assembly 300 is relatively far away from the body assembly 200, that is, the distance between the handle assembly 300 and the body assembly 200 is relatively large. At this time, the gravity of the heavier body assembly 200 and the floor brush assembly 100 acts on the surface to be cleaned, and the user's arm or wrist only needs to support the handle assembly 300 to push or pull the body assembly 200.

[0153] When a user uses the cleaning device 10, the user's wrist can maintain a natural posture, reducing discomfort in the hand or wrist and improving the comfort of operation.

[0154] It should be noted that the first sensing component can detect whether the body component 200 is in an upright state in any manner. For example, the first sensing component can obtain whether the body component 200 is in an upright state by detecting the angle between the body component 200 and the handle component 300. For another example, the first sensing component can obtain whether the body component 200 is in an upright state by detecting the angle between the body component 200 and the surface to be cleaned. The embodiments of the present application do not limit the detection method of the first sensing component, nor are they limited to the above examples.

[0155] The second sensing component is configured to detect the rotation of the handle component 300 relative to the body component 200 and trigger the output of the second signal, that is, the second sensing component can detect whether the handle component 300 and the body component 200 rotate.

[0156] A control module, the control module is electrically connected to the first sensing component and the second sensing component, and the control module is used to control the operation of the floor brush component 100 and the operation of the body component 200.

[0157] It is understandable that the work of the floor brush assembly 100 may include but is not limited to the rotation of the roller brush 110 of the floor brush assembly 100, the displacement of the floor brush assembly 100, etc.; the work of the body assembly 200 may include but is not limited to charging, cleaning, network connection, etc. The embodiments of the present application do not limit the specific work of the floor brush assembly 100 and the specific work of the body assembly 200, nor are they limited to the above examples.

[0158] The control module is configured to control the floor brush assembly 100 to enter a dormant state under the triggering of a first signal, and release the dormant state of the floor brush assembly 100 under the triggering of a second signal. The control module can realize the triggering and control of signals by setting a simple logic circuit.

[0159] According to the above content, the working process of the control module is as follows:

[0160] When the first sensing component detects that the body component 200 is in an upright state, a first signal is sent;

[0161] After receiving the first signal, the control module controls the floor brush assembly 100 to enter a dormant state;

[0162] When the second sensing component detects that the handle component 300 rotates, a second signal is sent;

[0163] After receiving the second signal, the control module releases the dormant state of the floor brush assembly 100 .

[0164] Through the design of the first sensing component and the second sensing component, the control module can intelligently control the working state of the floor brush component 100 according to the state of the body component 200 and the handle component 300. When the body component 200 is in an upright state, the floor brush component 100 enters a dormant state to avoid unnecessary energy consumption; and when the handle component 300 rotates, the floor brush component 100 is awakened and is in a working state, thereby improving the intelligence level and energy-saving effect of the cleaning device 10.

[0165] The cleaning device 10 provided in the embodiment of the present application can realize the dormancy and awakening of the floor brush assembly 100 when the body assembly 200 is in an upright state by setting a first sensing component and a second sensing component. When the body assembly 200 is in an upright state, the floor brush assembly 100 enters a dormant state to avoid unnecessary energy consumption and operation. When the handle assembly 300 rotates relative to the body assembly 200, the control module releases the dormant state of the floor brush assembly 100 according to the second signal and puts it into a working state.

[0166] Through the above-mentioned arrangement, the problem that the cleaning device 10 has a high center of gravity and is inconvenient to move in an upright state can be effectively solved. At the same time, the floor brush assembly 100 can be prevented from continuing to work when cleaning is not needed, which can save energy and extend the life of the equipment, improve the intelligence level of the cleaning device 10 and the user experience, and make cleaning work more convenient and efficient.

[0167] As an optional embodiment, the cleaning device further includes a clean water tank and a dirty water tank, and at least one of the clean water tank and the dirty water tank is installed on the floor brush assembly 100 .

[0168] It is understandable that the clean water tank and the dirty water tank are used to store cleaning water and collect dirty water, and at least one is installed on the floor brush assembly 100 to facilitate the water supply and dirty water collection during cleaning operations.

[0169] It should be noted that both the clean water tank and the sewage tank are relatively heavy.

[0170] When the clean water tank is installed on the floor brush assembly 100, the weight of the body assembly 200 is reduced, and the center of gravity of the body assembly 200 is relatively close to the surface to be cleaned, which can improve the working stability of the cleaning device 10;

[0171] When the sewage tank is installed on the floor brush assembly 100, the weight of the body assembly 200 is reduced, and the center of gravity of the body assembly 200 is relatively close to the surface to be cleaned, which can improve the working stability of the cleaning device 10;

[0172] When the sewage tank and the clean water tank are installed on the floor brush assembly 100 , the weight of the body assembly 200 is further reduced, and the center of gravity of the body assembly 200 is further relatively close to the surface to be cleaned, which can further improve the working stability of the cleaning device 10 .

[0173] Through the above-mentioned configuration, at least one of the clean water tank and the dirty water tank is installed on the floor brush assembly 100, which can reduce the overall volume of the equipment and lower the center of gravity of the cleaning equipment 10. On the one hand, it can improve the operational convenience and facilitate users to supply water and treat dirty water; on the other hand, it can improve the working stability of the cleaning equipment 10, reduce the difficulty of use for users, and thus improve the user experience.

[0174] Reference Figure 1-Figure 5 As shown, as an optional embodiment, the floor brush assembly 100 has a roller brush 110 for cleaning the surface to be cleaned, and the roller brush 110 is used to drive the floor brush assembly 100 to move on the surface to be cleaned.

[0175] The roller brush 110 is a power component, which is used to drive the floor brush assembly 100 to move on the surface to be cleaned, thereby achieving the cleaning operation.

[0176] Through the above arrangement, the roller brush 110 can help the cleaning device 10 move on the ground to provide a driving force. While completing the cleaning operation, it can better drive the floor brush assembly 100 to move on the surface to be cleaned, thereby improving the cleaning efficiency of the cleaning device 10.

[0177] As an optional embodiment, the handle assembly 300 includes a handle 310 and a connecting rod 320. One end of the connecting rod 320 is connected to the handle 310, and the other end of the connecting rod 320 is rotatably connected to the fuselage assembly 200.

[0178] It is understandable that the shape of the handle 310 can be in various forms such as a straight rod, a zigzag shape, a grip shape, etc. For example, a straight rod-shaped handle 310 may be suitable for occasions requiring a large operating force, a zigzag handle 310 may be suitable for occasions requiring delicate operations, and a grip-shaped handle 310 may be suitable for occasions requiring a comfortable grip. The present application embodiment does not limit the use scenario of the handle 310, nor is it limited to the above examples, and can be adjusted according to actual conditions.

[0179] It should be noted that the material and surface treatment of the handle 310 can also be adjusted according to user needs, such as anti-slip treatment, comfortable grip, etc., to improve the user's operating experience and the practicality of the cleaning device 10.

[0180] It is understandable that the shape of the connecting rod 320 can also be adjusted according to user needs, and the embodiment of the present application will not be described in detail. The following description will be given by taking the connecting rod 320 as a straight rod as an example.

[0181] It is understandable that the locking assembly 400 can be disposed on the handle 310 or on the connecting rod 320 , and both are used to fix or release the handle assembly 300 .

[0182] It should be noted that the locking assembly 400 is disposed on the connecting rod 320, that is, the locking assembly 400 is fixed on the connecting rod 320, and the locking assembly 400 is used to connect the body assembly 200. Since the connecting rod 320 is light in weight, and the connecting rod 320 is used for manipulation by the user, and the user adjusts the rotation angle between the body assembly 200 and the connecting rod 320 through the handle assembly 300, thereby controlling the cleaning device 10.

[0183] It should be noted that the function of rotating the handle 310 toward the user side can help the user to more accurately control the movement trajectory and cleaning range of the cleaning device 10, thereby improving the accuracy of the cleaning effect.

[0184] The connecting rod 320 is connected to the back side of the body assembly 200 .

[0185] The back of the body assembly 200 faces the user, that is, when the user operates the cleaning device 10, the back of the body assembly 200 faces the user, that is, the user can see the back of the body assembly 200 when facing the body assembly 200, so that the user can intuitively observe the back of the body assembly 200, understand the working status and cleaning effect of the cleaning device 10, and improve the convenience and control sense of the user's operation.

[0186] Through the above arrangement, the weight of the body assembly 200 can be effectively shared, the burden of the user during operation can be reduced, and the stability and operability of the device can be improved. In addition, by setting the connection point of the connecting rod 320 on the back of the body assembly 200, it can be ensured that the connection has sufficient support area and structural strength, thereby achieving the firmness and stability of the connection.

[0187] As an optional implementation, the control module is triggered by the second signal and the operation has a higher priority than the first signal, which means that when the control module is triggered by the first signal and the second signal at the same time, the operation triggered by the second signal will be executed first.

[0188] It should be noted that if the rotation of the connecting rod 320 is an action of the user actively operating the device, a priority response is required to ensure that the cleaning device 10 can work according to the user's intention.

[0189] By setting the operation priority of the control module to be higher when the second signal is triggered, it can be ensured that when the connecting rod 320 rotates, the floor brush assembly 100 can be awakened and enter the working state in time, thereby improving the response speed and efficiency of the cleaning device 10. In addition, it can be ensured that when the user actively operates the device, the cleaning device 10 can respond to the user's instructions in time, thereby improving the intelligence level of the device and the user experience.

[0190] Reference Figure 1-Figure 9 As shown, as an optional embodiment, the handle assembly 300 includes a handle 310 and a connecting rod 320. It can be understood that the relevant contents of the handle assembly 300 have been described above and will not be repeated here.

[0191] The connection position between the connecting rod 320 and the fuselage assembly 200 may be arbitrary.

[0192] In some embodiments, the connecting rod 320 is connected to the middle of the body assembly 200. When the connecting rod 320 is connected to the middle of the body assembly 200, more balanced operation and control can be provided, so that the cleaning device 10 is more stable and flexible when working, and instability and operational difficulties caused by the position offset of the connecting rod 320 can be avoided.

[0193] In some embodiments, the connecting rod 320 is connected to one end of the body assembly 200 close to the floor brush assembly 100. When the connecting rod 320 is connected to one end of the body assembly 200 close to the floor brush assembly 100, a larger inclination angle can be provided, so that the floor brush assembly 100 can clean the floor more deeply, improve the cleaning effect, adapt to the needs of different cleaning scenarios, and improve the applicability and flexibility of the cleaning device 10.

[0194] In some embodiments, the connecting rod 320 is connected to one end of the body assembly 200 away from the floor brush assembly 100. When the connecting rod 320 is connected to the end of the body assembly 200 away from the floor brush assembly 100, a larger operating space and field of view can be provided, so that the user can operate the cleaning device 10 more conveniently, thereby improving the convenience and efficiency of operation.

[0195] It can be understood that when the connecting rod 320 is connected to one end of the body assembly 200 away from the floor brush assembly 100, the connecting rod 320 can be rotated to the side of the body assembly 200 away from the surface to be cleaned, that is, the connecting rod 320 can be rotated to the top of the body assembly 200. At this time, the body assembly 200 can be set at an angle, which can lower the height of the cleaning device 10 and thereby reduce the volume of the cleaning device 10 for easy storage by the user.

[0196] As an optional embodiment, the connection point between the connecting rod 320 and the fuselage assembly 200 is higher than the center of gravity of the fuselage assembly 200. The connection point between the connecting rod 320 and the fuselage assembly 200 may refer to an end of the connecting rod 320 facing the fuselage assembly 200.

[0197] It can be understood that when the connection point is higher than the center of gravity of the body assembly 200, the center of gravity of the cleaning device 10 is more stable during operation, reducing the instability and shaking caused by the shift of the center of gravity, and improving the safety and stability of operation; in addition, it can reduce the labor intensity of the user during operation, making the cleaning work easier and more efficient, thereby facilitating the user to achieve more stable operation and control.

[0198] As an optional implementation, when the body assembly 200 is in an upright state, the angle between the extension direction of the body assembly 200 and the surface to be cleaned is 75° to 100°.

[0199] It can be understood that the specific angle between the extension direction of the fuselage assembly 200 and the surface to be cleaned can be 75°~76°, or 76°~79°, or 79°~80°, 80°~85°, 85°~90°, 90°~95°, 95°~100°, etc.

[0200] It should be noted that when the body component 200 is in the above position, the angle between the body component 200 and the surface to be cleaned is relatively large, the body component 200 and the surface to be cleaned are nearly vertically arranged, and the body component 200 can be placed on the surface to be cleaned relatively stably.

[0201] When the body assembly 200 is in an upright state, the angle between the extension direction of the body assembly 200 and the surface to be cleaned is set within the range of 75° to 100°, which can achieve a better cleaning effect. Within this angle range, the floor brush assembly 100 can fully contact the ground to ensure thorough cleaning; at the same time, the operator can easily control the tilt angle of the cleaning device 10, improving the convenience and efficiency of operation.

[0202] As an optional embodiment, the handle assembly 300 further includes a rotary motor, which is electrically connected to the control module. The output end of the rotary motor is transmission-connected to the connecting rod 320, and the fixed end of the rotary motor is connected to the body assembly 200. The rotary motor is configured to drive the connecting rod 320 to rotate relative to the body assembly 200.

[0203] It can be understood that the fixed end of the rotating motor is connected to the fuselage assembly 200 , which can ensure stable transmission and stable rotation of the rotating motor, so as to achieve stable rotation between the connecting rod 320 and the fuselage assembly 200 .

[0204] Through the above-mentioned setting, by setting the transmission connection between the rotating motor and the connecting rod 320, the handle assembly 300 can be automatically rotated to improve the convenience and efficiency of operation; in addition, the user can more easily control the tilt angle of the cleaning device 10 to complete the cleaning work.

[0205] As an optional embodiment, the handle assembly 300 further includes a button, which is electrically connected to the control module, and the control module is configured to control the rotation motor to operate when triggered by a signal from the button.

[0206] Through the connection between the button on the handle assembly 300 and the control module, the user can conveniently control the working state of the rotating motor. Pressing the button can start or stop the operation of the rotating motor, thereby realizing the automatic rotation of the handle assembly 300, improving the convenience and efficiency of operation.

[0207] As an optional implementation, the locking assembly 400 is disposed on the back side of the body assembly 200 , and the locking assembly 400 is an elastic buckle used in conjunction with the connecting rod 320 ; the elastic buckle is used to fix or release the connecting rod 320 .

[0208] It should be noted that the types of elastic snap fasteners can be various.

[0209] Exemplarily, the elastic snap fastener may be a spring snap ring, which is a circular elastic snap fastener, usually used for fixing on a bearing or a shaft, and has the characteristics of easy installation and easy disassembly.

[0210] Exemplarily, the elastic snap-fitting part may be a spring pin, which is a pin with a spring, and fixes the connecting part by compressing the spring, thereby providing a certain vibration absorption and buffering effect.

[0211] Exemplarily, the elastic snap fastener may be a spring clip, which is a connector that fixes components through elastic deformation and has the characteristics of simple structure and easy installation.

[0212] Exemplarily, the elastic snap-fitting part may be a spring pin, which is a pin with a spring, and the connection is achieved by compressing the spring, which can provide a certain anti-loosening effect.

[0213] Exemplarily, the elastic snap fastener may be an elastic snap ring, which is a circular elastic snap fastener having the characteristics of simple structure and easy installation.

[0214] It is understandable that the embodiments of the present application do not limit the specific type of the elastic clip, nor are they limited to the above examples.

[0215] It is understandable that by arranging the locking assembly 400 on the back of the fuselage assembly 200 and using an elastic buckle used in conjunction with the connecting rod 320, stable fixation and stable release can be achieved. The elastic buckle has good elasticity and durability, which can ensure that the connecting rod 320 is firmly fixed on the fuselage assembly 200 during operation, thereby improving the stability and safety of the operation.

[0216] Through the above arrangement, the connection rod 320 and the body assembly 200 can be stably locked and unlocked, thereby improving the stability and safety of the operation and facilitating the user to switch the operation when necessary.

[0217] Reference Figure 1-Figure 9 As shown, as an optional embodiment, the cleaning device 10 further includes a locking assembly 400, which is disposed on the body assembly 200 or the connecting rod 320, and is used to fix or release the handle assembly 300. It is understandable that the relevant contents of the locking assembly 400 have been described above and will not be repeated here.

[0218] By providing the locking assembly 400, the connecting rod 320 and the body assembly 200 can be fixed when needed to ensure the stability and safety of the device. At the same time, when release is required, the user can easily operate the locking assembly to conveniently disassemble or adjust the device.

[0219] As an optional implementation, the locking assembly 400 includes a safety self-locking module, and the safety self-locking module is used to trigger the safety self-locking state of the locking assembly 400 to achieve the safety self-locking function of the locking assembly.

[0220] It is understandable that the safety self-locking module can be a mechanical or electronic device that can ensure that the locking component 400 automatically enters a safety self-locking state under specific conditions, thereby ensuring that the locking component is in a safe state and avoiding accidental unlocking or operational errors that may cause the cleaning equipment to be unstable or unsafe.

[0221] The locking assembly 400 cannot be unlocked in the safety self-locking state, and the safety self-locking module is electrically connected to the control module. The non-upright state may refer to the body assembly being tilted, inverted or in other abnormal states.

[0222] The first sensing component is configured to detect that the body component 200 is in a non-upright state and trigger the output of the third signal. In this way, by detecting the non-upright state and outputting the third signal by the first sensing component, the abnormal state of the cleaning device 10 can be discovered in time, the safety and stability of the cleaning device 10 can be improved, and the safety of the device and the user can be guaranteed.

[0223] The control module is configured to output a safety self-locking signal to the safety self-locking module under the triggering of the third signal, so that the locking assembly 400 is switched to a safety self-locking state.

[0224] By controlling the module to output a safety self-locking signal when the third signal is triggered, the safety self-locking function can be automatically started in an abnormal state of the equipment, thereby ensuring the safety of the equipment and users and preventing accidents.

[0225] As an optional embodiment, the second sensing component is disposed on the locking component 400, which is a photoelectric sensor or a micro switch. The second sensing component is configured to output a second signal to the control module when the handle assembly 300 is disengaged from the locking assembly 400.

[0226] It can be understood that a photoelectric sensor is a sensor that can convert light signals into electrical signals, using the photoelectric effect or photosensitivity effect. When light shines on a photoelectric element, the photoelectric element will generate an electric charge or current, and this electrical signal can be converted into a digital signal or an analog signal by a signal processing circuit, thereby realizing the detection and measurement of the light signal, and then the presence, intensity, position and change of light can be detected.

[0227] In an embodiment of the present application, when the body assembly 200 and the connecting rod 320 are locked, the optical signal sensed by the second sensing component does not change; when the connecting rod 320 rotates relative to the body assembly 200, the intensity of the optical signal changes, and the second sensing component can determine whether the connecting rod 320 rotates relative to the body assembly 200 by the change of the optical signal between the body assembly 200 and the connecting rod 320.

[0228] It is understood that a micro switch is a mechanical switch, which is usually composed of a movable arm and a contact point. In the above description, the second sensing component can also be a micro switch, which is used to detect the connection state between the handle component 300 and the locking component 400. When the handle component 300 is separated from the locking component 400, the movable arm of the micro switch will be affected by an external force and change its position, causing the contact point to close or open, thereby outputting a second signal to the control module.

[0229] Through the above-mentioned setting, a photoelectric sensor or a micro switch is set on the locking component 400 as the second sensing component, which can accurately sense the position of the locking component 400, ensure the accuracy and stability of fixing and releasing, improve the convenience and safety of operation, and enhance the intelligence level of the cleaning device 10, thereby improving the convenience and safety of operation of the cleaning device 10.

[0230] As an optional embodiment, the second sensing component is disposed between the connecting rod 320 and the fuselage component 200, which is a torque sensor, and is configured to output a second signal to the control module when the connecting rod 320 rotates relative to the fuselage component 200. The torque sensor can be used to obtain the torque between the connecting rod 320 and the fuselage component 200.

[0231] A torque sensor is a sensor used to measure the torque (torque) of an object. It uses the deformation of a strain gauge to measure torque. When the object is subjected to torque, the strain gauge will deform, and the deformation will cause a change in resistance. The sensor chip will convert this change into an electrical signal output to obtain an accurate torque value. It is usually used to measure and monitor the size and changes of torque.

[0232] In an embodiment of the present application, when the body assembly 200 and the connecting rod 320 are locked, the torque sensed by the second sensing assembly does not change; when the connecting rod 320 rotates relative to the body assembly 200, the torque changes, and the second sensing assembly can determine whether the connecting rod 320 rotates relative to the body assembly 200 by the change in torque between the body assembly 200 and the connecting rod 320.

[0233] Through the above-mentioned setting, a torque sensor is set between the connecting rod 320 and the body assembly 200 as the second sensing component to achieve stable fixation and stable release of the connecting rod 320 and the body assembly 200, and the torque size between the connecting rod 320 and the body assembly 200 can be accurately obtained, which helps the user to monitor the torque of the connecting rod 320 in real time, thereby controlling the rotation force of the connecting rod 320 to make the operation more precise and stable.

[0234] As an optional embodiment, the cleaning device 10 also includes a power-assisting wheel 500 and a stress sensor. The stress sensor is arranged at the connection between the handle assembly 300 or the connecting rod 320 and the body assembly 200. The stress sensor is electrically connected to the control module. The stress sensor is used to detect and obtain the force applied by the user to the handle 310.

[0235] It is understandable that the stress sensor is a sensor used to detect and measure the force applied to an object, and is generally used to measure the force applied by the user to the handle 310. In the cleaning device 10, the stress sensor is disposed at the connection between the handle assembly 300 or the connecting rod 320 and the body assembly 200, and is used to obtain the magnitude of the force applied by the user to the handle 310, so as to monitor in real time and provide data support for the control module, thereby achieving smarter and more accurate device operation.

[0236] In some embodiments, the stress sensor is configured to output a pressure signal under the action of pressure, and the control module is configured to output an acceleration signal to the power-assisted wheel 500 when triggered by the pressure signal.

[0237] In some embodiments, the stress sensor is configured to output a tension signal under the action of a tension, and the control module is configured to output a deceleration signal to the power-assisted wheel when triggered by the tension signal.

[0238] By detecting the pressure or tension of the user on the handle 310 through the stress sensor, the user's operating intention and strength can be obtained in real time, providing accurate data support for subsequent equipment control, and improving the intelligence level and user experience of the cleaning device 10. By outputting an acceleration signal to the power-assisted wheel when the pressure signal is triggered or outputting a deceleration signal when the tension signal is triggered by the control module, the operating speed and strength of the power-assisted wheel can be adjusted according to the user's operating strength and needs, thereby improving the flexibility and adaptability of the cleaning device 10 to meet the needs of the user.

[0239] In some other embodiments, the stress sensor may be a pressure sensor. The cleaning device 10 may include two pressure sensors, both of which are electrically connected to the control module. The two pressure sensors are located on opposite sides of the handle 310 .

[0240] If the pressure sensor on the side of the handle 310 facing the user outputs a pressure signal, the control module is configured to output an acceleration signal to the power-assisted wheel 500 under the triggering of the pressure signal.

[0241] If the pressure sensor on the side of the handle 310 facing away from the user outputs a pressure signal, the control module is configured to output a deceleration signal to the power-assisted wheel 500 under the triggering of the pressure signal.

[0242] As an optional implementation, the locking assembly 400 includes a first elastic snap member 401 and a second elastic snap member 402 . The first elastic snap member 401 and the second elastic snap member 402 are located at two sides of the connection between the fuselage assembly 200 and the connecting rod 320 .

[0243] When the connecting rod 320 rotates to the top of the body assembly 200 , it is clamped into the first elastic clamping piece 401 . When the connecting rod 320 rotates to the bottom of the body assembly 200 , it is clamped into the second elastic clamping piece 402 .

[0244] It is understandable that the types of elastic clips have been described in the previous text and will not be repeated here.

[0245] It should be noted that the types of the two elastic buckles can be the same or different.

[0246] Through the above arrangement, the first elastic fastener 401 and the second elastic fastener 402 are respectively located on both sides of the connection between the body assembly 200 and the connecting rod 320, which can ensure the stable connection between the connecting rod 320 and the body assembly 200. When the connecting rod 320 is inserted into the first elastic fastener 401, the connecting rod 320 and the body assembly 200 are relatively locked, ensuring that the device will not loosen or fall off in the working state. When the connecting rod 320 is inserted into the second elastic fastener 402, the body assembly 200 is in an upright state, which is convenient for the user to switch operations, so that the device can be quickly converted to a working state or a resting state, improving the convenience and flexibility of operation.

[0247] As an optional implementation, the locking assembly 400 is disposed on the fuselage assembly 200 and / or the connecting rod 320 to ensure a stable connection between the connecting rod 320 and the fuselage assembly 200 .

[0248] The locking assembly 400 is one or more magnetic components used in conjunction with the connecting rod 320 , and the magnetic components are used to magnetically connect the connecting rod 320 and the fuselage assembly 200 .

[0249] It is understandable that the number of magnetic parts can be arbitrary. For example, the locking assembly 400 can include only one magnetic part, and the magnetic part can cooperate with metal, such as at least one of the connecting rod 320 and the fuselage assembly 200 is metal, thereby achieving magnetic connection. Another example, the locking assembly 400 can also include multiple magnetic parts, and the multiple magnetic parts can be attracted to or repelled from each other, thereby achieving magnetic connection.

[0250] It is understandable that the types of magnetic members can be various.

[0251] Exemplarily, the magnetic part is a magnet, which is usually made of materials such as iron oxide, nickel, and cobalt, and has functions such as adsorption, fixation, and transmission.

[0252] Exemplarily, the magnetic part is a magnetic suction cup, which is a magnetic suction cup usually used to adsorb metal objects and has the characteristics of strong adsorption force and easy use.

[0253] Exemplarily, the magnetic part is a magnetic clamp, which is a clamp that uses magnetic adsorption force to fix the workpiece, has the advantages of firm fixation and easy operation, and improves work efficiency.

[0254] Exemplarily, the magnetic part is a magnetic label, which is a magnetic label usually used to be attached to a metal surface and has the characteristics of being easy to replace and reusable.

[0255] It is understandable that the embodiments of the present application do not limit the specific types of magnetic components, nor are they limited to the above examples.

[0256] When the magnetic member is magnetically connected to the connecting rod 320, the connecting rod 320 and the body assembly 200 are relatively locked;

[0257] When the magnetic member is not magnetically connected to the connecting rod 320 , the body assembly 200 is in an upright state.

[0258] It should be noted that when the locking assembly 400 is a magnetic component, the connecting rod 320 may be a metal rod, so that the locking assembly 400 can adsorb the connecting rod 320 .

[0259] Through the above arrangement, by designing the locking assembly 400 as a magnetic part, the magnetic connection between the connecting rod 320 and the fuselage assembly 200 can be achieved, thereby simplifying the connection process and improving the stability of the connection. When the connection needs to be released, the magnetic connection can be released by simply moving the connecting rod 320 away from the fuselage assembly 200, which is convenient for maintenance and replacement of parts.

[0260] Furthermore, when the magnetic member is magnetically connected to the connecting rod 320, the connecting rod 320 and the body assembly 200 are relatively locked, ensuring that the device will not loosen or fall off in the working state. When the magnetic member is not magnetically connected to the connecting rod 320, the body assembly 200 is in an upright state, which is convenient for the user to switch operations, so that the device can be quickly switched to a working state or a resting state, improving the convenience and flexibility of operation.

[0261] As an optional implementation, the locking assembly 400 is disposed at the rotational connection of the connecting rod 320 to lock the connecting rod 320 at multiple rotational angles.

[0262] It is understandable that the locking assembly 400 may have a plurality of gear positions at different angles to correspond to a plurality of different rotation angles between the connecting rod 320 and the fuselage assembly 200 .

[0263] It should be noted that when the cleaning device 10 includes a second sensing component, the user can determine the specific angle between the connecting rod 320 and the body component 200 through the second sensing component, so that the locking component 400 can correspondingly lock at different angles to adapt to users of different heights.

[0264] Through the above-mentioned arrangement, the locking assembly 400 is arranged at the rotation connection of the connecting rod 320, and multiple rotation angles of the connecting rod 320 can be flexibly locked, so that the connecting rod 320 can be stably maintained at different working angles, thereby ensuring the stability and reliability of the floor brush assembly 100 in different working conditions, and improving the operability and use effect of the equipment.

[0265] Reference Figure 6-Figure 9 As shown, it is an optional embodiment, the side of the body assembly 200 facing the user has a mounting groove 201 and a first mounting hole 202 formed in the groove wall of the mounting groove 201; one end of the connecting rod 320 is located in the mounting groove 201, and the connecting rod 320 is provided with a rotating shaft 330 at the position corresponding to the first mounting hole 202, the rotating shaft 330 is located in the first mounting hole 202, and the connecting rod 320 is rotatably connected to the body assembly 200 via the rotating shaft 330.

[0266] It can be understood that the mounting groove 201 and the first mounting hole 202 provide a position and structural support for the connection between the connecting rod 320 and the fuselage assembly 200. One end of the connecting rod 320 is located in the mounting groove 201 and is rotatably connected to the fuselage assembly 200 through the rotating shaft 330. The rotating shaft 330 is located in the first mounting hole 202. The connecting rod 320, the fuselage assembly 200 and the rotating shaft 330 can form a stable connection structure.

[0267] It should be noted that the shapes of the mounting groove 201 and the first mounting hole 202 may correspond to the shapes of the connecting rod 320 and the rotating shaft, respectively. Exemplarily, when the connecting rod 320 is a rod body with a square cross-section, the mounting groove 201 may be a corresponding square groove, so that the end of the connecting rod 320 may be located in the mounting groove 201. Exemplarily, when the connecting rod 320 is a rod body with a circular cross-section, the mounting groove 201 may be a corresponding circular groove, so that the end of the connecting rod 320 may be located in the mounting groove 201. Exemplarily, when the rotating shaft 330 is a cylindrical rotating shaft 330, the opening shape of the first mounting hole 202 may be circular, so that the rotating shaft 330 may rotate in the first mounting hole 202.

[0268] Through the above configuration, the mounting groove 201 and the first mounting hole 202 are provided on the side of the body assembly 200 facing the user, so as to realize the connection structure between the connecting rod 320 and the body assembly 200. One end of the connecting rod 320 is rotatably connected to the body assembly 200 through the rotating shaft 330, and the rotating shaft 330 is located in the first mounting hole 202, so as to ensure the stability and flexibility of the connection. The connecting rod 320 is rotatably connected to the body assembly 200 through the rotating shaft 330, so that the user can easily turn the cleaning device 10 from the upright state to the working state, thereby improving the convenience and efficiency of the operation.

[0269] As an optional implementation, the mounting groove 201 is a curved groove adapted to the connecting rod 320 .

[0270] Through the above arrangement, the arcuate groove can make the connecting rod 320 fully contact with the groove wall of the installation groove 201, so that the groove wall of the installation groove 201 can be fully stressed, which can enhance the traveling stability of the cleaning device 10.

[0271] Reference Figure 6-Figure 9 As shown, as an optional embodiment, the connecting rod 320 is a hollow rod, and the side of the connecting rod 320 facing the fuselage assembly 200 has a limiting hole 321, the limiting hole 321 is connected to the inside of the connecting rod 320, and the fuselage assembly 200 also has a second mounting hole 203 spaced apart from the first mounting hole 202, and the second mounting hole 203 corresponds to the limiting hole 321.

[0272] The locking assembly 400 includes a handle 410, a pull cord 420 and a telescopic member 430. The handle 410 is rotatably arranged on the handle 310, and the two ends of the pull cord 420 are respectively connected to the handle 410 and the telescopic member 430. The two ends of the telescopic member 430 can move relative to each other, and the pull cord 420 is used to drive the telescopic member 430 to extend and retract.

[0273] The telescopic member 430 is arranged at the connection where the connecting rod 320 rotates relative to the installation groove 201, and the telescopic member 430 includes a connected slider 431 and a spring 432; the telescopic member 430 can be automatically reset by the spring 432, and the installation groove 201 is provided with a plurality of limiting holes 321 cooperating with the telescopic member 430 along the rotation direction of the connecting rod 320. The rotation of the handle 410 drives the pull rope 420 to drive the telescopic member 430 to extend and retract.

[0274] Specifically, the handle 410 has a control part 411 and a rotating part 412 that are relatively arranged, and the rotating part 412 can be rotatably connected to the handle 310; the pull rope 420 is connected to the rotating part 412 of the handle 410, and the end of the pull rope 420 away from the handle 410 is located in the connecting rod 320; the number of sliders 431 is two, and the two sliders 431 are both connected to the end of the pull rope 420 away from the handle 410, and the slider 431 passes through the limiting hole 321 and is located in the second mounting hole 203; the spring 432 is located between the two springs 432.

[0275] It should be noted that when the connecting rod 320 rotates, the position of the slider 431 changes. For this reason, the limiting hole 321 can be set as an arc hole so that the slider 431 is located in the second mounting hole 203 before and after the rotation.

[0276] The working process of the locking assembly 400 is as follows:

[0277] When the user does not hold the control portion 411 of the handle 410 , the handle 410 is not pulled; under the action of the spring 432 , the two sliders 431 are respectively located in the corresponding second mounting holes 203 , and the connecting rod 320 is locked with the body assembly 200 .

[0278] When the user holds the control part 411 of the handle 410 and the control part 411 rotates relative to the rotating part 412 away from the fuselage assembly 200, that is, when the handle 410 is pulled, the pull rope 420 is pulled, and both sliders 431 are pulled and compress the spring 432, and the slider 431 disengages from the second mounting hole 203, thereby contacting and locking the connecting rod 320 and the fuselage assembly 200.

[0279] Through the above arrangement, the connecting rod 320 can be flexibly connected to the fuselage assembly 200, and the rotation connection is realized through the rotating shaft 330, so as to realize the stable connection between the connecting rod 320 and the fuselage assembly 200. The control part 411 and the rotating part 412 of the handle 410 are respectively connected to the connecting rod 320 and the handle 310, and the pull rope 420 is connected to the inside of the connecting rod 320 through the slider 431. The mutual cooperation can realize the locking and unlocking of the handle assembly 300 and the fuselage assembly 200, and ensure the stability and safety of the operation. The two sliders 431 are provided with the limiting holes 321 and are located in the second mounting hole 203. The spring 432 is located between the two sliders 431. Through the action of the spring 432, the stable locking and flexible rotation between the connecting rod 320 and the fuselage assembly 200 can be realized.

[0280] Reference Figure 6-Figure 9 As shown, as an optional implementation, a groove wall of the installation groove 201 is provided with a plurality of first clamping members 440 arranged at intervals, and a plurality of second clamping members 450 are provided on one side of the connecting rod 320 facing the first clamping members 440 .

[0281] It is understandable that the number of the first clamping member 440 and the second clamping member 450 can be arbitrary. For example, the number of the first clamping member 440 and the second clamping member 450 can be two, three, four, five, six, seven, eight, etc. The embodiment of the present application does not limit the specific number of the first clamping member 440 and the second clamping member 450, nor is it limited to the above example.

[0282] It should be noted that the plurality of second clamping members 450 correspond one to one with the plurality of first clamping members 440. Among them, one of the first clamping member 440 and the second clamping member 450 is a clamping groove, and one of the first clamping member 440 and the second clamping member 450 is a clamping piece, which is clamped in the clamping groove to complete the clamping connection between the connecting rod 320 and the fuselage assembly 200.

[0283] It is understandable that a plurality of card slots can be arranged at intervals along the rotation direction of the connecting rod 320 to correspond to different angles, thereby forming gears at multiple angles. Among them, the card sheet can have a bending area 441, so that the card sheet can have a self-locking function. Exemplarily, when the user disengages the slider 431 from the second mounting hole 203 through the handle 410, the bending area 441 of the card sheet disengages from one of the card slots, and the connecting rod 320 can rotate. As the connecting rod 320 rotates, the user pushes the card handle 410, the slider 431 enters the second mounting hole 203, and the card sheet rotates to other card slots to achieve gear changes at different rotation angles.

[0284] Through the above arrangement, the plurality of second clamping members 450 correspond to the plurality of first clamping members 440 one by one, so as to realize the stable connection between the connecting rod 320 and the fuselage assembly 200, and the interval arrangement of the first clamping members 440 and the second clamping members 450 ensures the stability of the connection. One of the first clamping member 440 and the second clamping member 450 is a clamping groove, and the other is a clamping piece, which is clamped in the clamping groove to realize the alignment and connection between the connecting rod 320 and the fuselage assembly 200, and can realize the stable locking and flexible rotation between the connecting rod 320 and the fuselage assembly 200.

[0285] Reference Figure 1-Figure 5 As shown, as an optional embodiment, the cleaning device 10 also includes a power-boosting wheel 500, and the number of the power-boosting wheels 500 is two, and the two power-boosting wheels 500 are arranged at intervals; the power-boosting wheel 500 is connected to the side of the floor brush assembly 100 facing the user, and is used to drive the floor brush assembly 100 to move on the surface to be cleaned.

[0286] The power-assisted wheel 500 is used to provide additional propulsion force to help the cleaning device 10 move on the ground, reduce the user's operating force, and make the cleaning work easier and more efficient.

[0287] It is understandable that the two power-assisted wheels 500 are arranged at intervals, which can balance the support and stability of the floor brush assembly 100, avoid the instability of a single wheel, and effectively improve the mobility and stability of the cleaning device 10 on the surface to be cleaned. In addition, the power-assisted wheel 500 is connected to the side of the floor brush assembly 100 facing the user, which can make it easier for the user to control and navigate the cleaning device 10, thereby improving the convenience and accuracy of operation.

[0288] It should be noted that in order to ensure the movement stability of the floor brush assembly 100, a power-assisting wheel 500 with a larger diameter can be provided to increase the contact area between the power-assisting wheel 500 and the surface to be cleaned, thereby enhancing the contact strength between the floor brush assembly 100 and the surface to be cleaned, thereby ensuring the working stability of the cleaning device 10.

[0289] By providing the above-mentioned power-assisted wheel 500, the floor brush assembly 100 can be better driven to move on the surface to be cleaned, thereby improving the cleaning efficiency of the cleaning device 10. In addition, the cleaning device 10 can be made more stable and flexible during operation, thereby improving the cleaning effect and user experience, and making the cleaning device 10 more efficient, stable and easy to operate during use.

[0290] As an optional embodiment, when the cleaning device 10 further includes a power-assisted wheel 500, the cleaning device 10 further includes a speed sensor, which is disposed on the side of the handle assembly 300 facing the user, and the speed sensor is used to detect and obtain the user's speed information. The power-assisted wheel 500 is configured to change the travel speed according to the user's speed information.

[0291] Through the above configuration, the speed sensor is arranged on the side of the handle assembly 300 facing the user, and can detect the user's operating speed information in real time to reflect the user's cleaning operating habits. The power-assisted wheel 500 can adjust the travel speed of the floor brush assembly 100 according to the user speed information obtained by the speed sensor, so that the cleaning device 10 is more intelligent and in line with the user's operating habits, thereby improving the intelligence level and operating convenience of the cleaning device 10.

[0294] Through the above settings, the wheel hub motor can change the speed difference between the two power-assisted wheels 500, realize flexible adjustment of the direction of travel of the floor brush assembly 100, and enhance the maneuverability and operability of the cleaning device 10. In addition, the user can adjust the speed difference of the power-assisted wheels 500 as needed to realize the movement and steering of the cleaning device 10 in different directions, thereby improving the cleaning efficiency and applicability. Secondly, by controlling the wheel hub motor, accurate navigation and positioning of the floor brush assembly 100 can be achieved to ensure the accuracy and integrity of the cleaning operation.

[0295] As an optional embodiment, the cleaning device further includes an infrared sensor, which is disposed on a side of the handle assembly 300 facing the user, and is used to detect a rotatable space of the connecting rod 320 .

[0296] It can be understood that an infrared sensor is a sensor device that can detect and sense infrared radiation. It usually uses the interactive relationship between infrared radiation and objects to achieve detection and control by measuring the infrared radiation emitted or reflected by the object. Its advantages include no need to contact the target, suitability for harsh environments, and fast response speed.

[0297] Through the above configuration, the infrared sensor is arranged on the side of the handle assembly 300 facing the user, and can detect the rotatable space of the connecting rod 320 in real time, reflecting the position information of the connecting rod 320. Through the infrared sensor, the user can monitor the position state of the connecting rod 320, help the control module to determine the rotation of the connecting rod 320, and thus realize the dormancy and wake-up control of the floor brush assembly 100. Furthermore, the user can determine the position state of the connecting rod 320 according to the signal of the infrared sensor, and then control the working state of the floor brush assembly 100, thereby improving the intelligence level and user experience of the cleaning device 10.

[0299] It is understandable that the types of the first damping member and the second damping member can be arbitrary and can be selected according to actual conditions. In addition, the first damping member and the second damping member can have the same structure or different structures. The specific types of damping members are given below as examples, which can be applicable to the first damping member or the second damping member.

[0300] Exemplarily, the damping element may be a liquid damper, which utilizes the viscosity and resistance of the fluid to achieve a damping effect, and different damping forces may be achieved by adjusting the viscosity and flow velocity of the fluid.

[0301] Exemplarily, the damping element may be a spring damper, which utilizes the deformation and rebound of a spring to absorb energy and mitigate vibration, and has the advantages of simple structure, high reliability, and low maintenance cost.

[0302] Exemplarily, the damping element may be a gas damper, which utilizes the compression and expansion of gas to achieve a damping effect, and has the advantages of fast response speed, adjustable damping force, and no liquid leakage.

[0303] Exemplarily, the damping element may be a friction damper, which utilizes friction to achieve a damping effect. Different damping forces may be achieved by adjusting the material and surface treatment of the friction surface. It has the advantages of simple structure, high reliability, and low maintenance cost.

[0304] Exemplarily, the damping element may be a magnetic fluid damper, which uses the influence of a magnetic field on a liquid to adjust the damping force, and has the advantages of adjustable damping force, fast response speed, and no friction and wear.

[0305] Exemplarily, the damping element may be an elastic damper, which utilizes the deformation and rebound of elastic materials to achieve the damping effect, and has the advantages of strong energy absorption capacity, wear resistance and long service life.

[0306] Through the above-mentioned arrangement, the rotational connection between the first damping member and the second damping member can realize the rotational connection between the connecting rod 320 and the body assembly 200 and provide a damping effect. When the connecting rod 320 rotates, a damping force can be provided to control the movement speed and stability of the connecting rod 320, and the rotation between the connecting rod 320 and the body assembly 200 can be smoother and more controllable, which helps to control the tilt and rotation of the cleaning equipment 10 and improve the stability and safety of the operation.

[0307] As an optional embodiment, a ratchet is provided at one end of the connecting rod 320 facing the fuselage assembly 200, and a pawl is provided at the position of the fuselage assembly 200 for connecting the connecting rod 320. Both the ratchet and the pawl have a plurality of locking teeth arranged at intervals, and the ratchet and the pawl are rotationally connected or fixed by the locking teeth.

[0308] Through the above arrangement, the ratchet and the pawl can realize the rotational connection or fixation between the connecting rod 320 and the body assembly 200. The locking teeth can realize the rotational connection or fixation between the ratchet and the pawl within a specific angle range, ensuring the stability and safety of the connecting rod 320 and the body assembly 200 in the working state, and realizing the reliable connection or fixation between the connecting rod 320 and the body assembly 200, so that the rotation and operation of the cleaning device 10 in different working states are more stable and controllable.

[0310] Through the above arrangement, the connection rod 320 and the body assembly 200 can be flexibly rotated and connected, and the position of the connection rod 320 can be adjusted by sliding the slider 431. A slide rail is arranged on the side of the body assembly 200 facing the user, and the extension direction of the slide rail is the same as the extension direction of the body assembly 200, so that the slide rail and the body assembly 200 maintain the same direction, which is convenient for the movement and adjustment of the connection rod 320.

[0311] As an optional implementation, the connecting rod 320 is a telescopic rod, one end of which is connected to the body assembly 200 , and the other end of which is connected to the handle 310 .

[0312] Through the above arrangement, the connecting rod 320 adopts a telescopic rod design, which can realize that the length of the connecting rod 320 is adjustable, and the user can adjust the length of the connecting rod 320 according to the actual situation, thereby controlling the inclination angle and position of the fuselage assembly 200, so that the floor brush assembly 100 is in a suitable working state. Through the flexible adjustment of the telescopic rod, the user can more conveniently control the operation of the cleaning device 10, improve the efficiency and convenience of the cleaning work. In addition, the telescopic rod is easy to store, thereby reducing the space required for storing the cleaning device 10, which is conducive to the transportation of logistics and the reduction of packaging costs.

[0313] As an optional implementation, the cleaning device 10 may include a control module with information processing capability. The control module may be electrically connected to any of the above sensors and send out corresponding electrical signals according to the information detected by the sensor.

[0314] Furthermore, the cleaning device 10 also includes a prompt module for prompting the user, and the prompt information of the prompt module includes but is not limited to voice, vibration, light, etc.

[0315] Exemplarily, when the cleaning device 10 is in the power saving mode:

[0316] The cleaning device 10 needs to simultaneously meet two conditions, namely, the body is in an upright state and the connecting rod 320 is away from the body assembly 200, before the operation of the floor brush assembly 100 can be started; if the above two conditions are not met, the control module will automatically adjust to meet the corresponding conditions or remind through the prompt module.

[0317] If the connecting rod 320 is locked with the body assembly 200, the floor brush assembly 100 stops running and exits the labor-saving mode.

[0318] Exemplarily, when the cleaning device 10 is in the normal mode, the floor brush assembly 100 is turned off;

[0319] The normal mode will be exited only when the two conditions of the fuselage being in an upright state and the connecting rod 320 being locked with the fuselage assembly 200 are met at the same time. If the above two conditions are not met, the control module will automatically adjust to meet the corresponding conditions or remind through the prompt module.
