[0070] like Figures 1 to 28 As shown, the cleaning system of the embodiment of the present disclosure includes a dust collecting pile 2 and a cleaning robot 1 .

[0071] In the technical solution provided by the embodiment of the present disclosure, the cleaning robot includes a robot body. The robot body may have an approximately circular shape, or may have other shapes, including but not limited to an approximately D-shaped shape with a front and a rear circle.

[0072] The cleaning robot may also include a cleaning system, a perception system, a control system, a drive system, an energy system, and a human-computer interaction system. The various systems coordinate with each other so that the cleaning robot can move autonomously to achieve the cleaning function. The functional elements constituting the above-mentioned systems in the cleaning robot can be integrated in the cleaning robot body. The cleaning robot body may include an upper cover, a chassis, and a middle frame arranged between the upper cover and the chassis. The middle frame can serve as a basic framework for setting various functional elements. The upper cover and the chassis cover the surface of the device body, play a role in protecting the internal components, and can enhance the aesthetics of the cleaning robot.

[0073] The perception system is used by the cleaning robot to perceive the external environment such as terrain and the cleaning robot's own position and posture, and can provide the cleaning robot's control system with various position information and motion status information of the machine.

[0074] In the technical solution provided by the embodiment of the present disclosure, the perception system may include a position determination device, which includes but is not limited to an infrared transmitting and receiving device, a camera, and a laser distance sensor (LDS). The position determination device may be set on the top or side of the cleaning robot. During the movement of the cleaning robot, the position determination device obtains the current position of the cleaning robot by determining the distance between the cleaning robot and the surrounding obstacles.

[0075] The buffer is used to buffer the collision between the robot body and surrounding objects during movement. A layer of soft rubber is provided on the surface of the buffer, and when the buffer is installed to the device body, it is separated from the device body by a predetermined distance, so as to ensure that the device body has enough deceleration time when a collision occurs.

[0076] The control system is arranged on the circuit board inside the robot body. It can be understood that the circuit board is provided with various control circuits for controlling the operation of the cleaning robot. The control system includes non-temporary memory, computing processor, etc. The computing processor can be a central processing unit, an application processor, etc., and a real-time map of the environment in which the cleaning robot is located is drawn using a positioning algorithm based on the obstacle information fed back by the laser ranging device. And combined with the distance information and speed information fed back by the buffer and the sensor device, it is comprehensively judged what working state the cleaning robot is currently in, such as crossing the threshold, getting on the carpet, being stuck on the cliff, above or below, the dust box is full, being picked up, etc., and specific next action strategies are given for different situations, so that the work of the cleaning robot is more in line with the requirements and the user experience is improved.

[0077] The human-machine interaction system may include buttons on the host panel for users to select functions; it may also include a display screen and / or indicator lights and / or speakers, which display the current state of the machine or function options to the user; it may also include a mobile client program. The cleaning robot can display a map of the robot's environment, the location of the cleaning robot, and the status information of the cleaning robot to the user through the mobile client program.

[0078] The energy system is used to provide electrical energy for the functional components of each system, and mainly includes rechargeable batteries and power supply circuits. The rechargeable batteries can be nickel-metal hydride batteries and lithium batteries. When the power in the rechargeable battery is lower than the predetermined minimum power, it can be charged by connecting to the charging device through the charging electrodes arranged on the side or below the device body.

[0079] In addition, the cleaning robot also includes a cleaning mechanism, which is arranged on the robot body. The cleaning mechanism removes debris from the surface to be cleaned by interfering with the surface to be cleaned.

[0080] The cleaning mechanism comprises a wet cleaning part and a dry cleaning part. The wet cleaning part can be a flat mop connected to the robot body.

[0081] The dry cleaning part can be a sweeping roller brush. Through the cooperation of the sweeping roller brush, dust box, fan, etc., the ground impurities are sucked into the dust box through the negative pressure generated by the fan, that is, the ground impurities enter the dust box through the garbage inlet of the robot body.

[0082] In the technical solution provided in the embodiment of the present disclosure, the dust collecting pile includes a main body 10, a dust bucket 20 and a fan assembly 40.

[0083] like Figures 2 to 6 As shown, the body 10 includes a dust inlet channel 11 , and the dust inlet channel 11 has a dust inlet port 111 . The dust inlet port 111 is used to communicate with the dust box so that the dust in the dust box can enter the dust inlet channel 11 through the dust inlet port 111 .

[0084] Combination Figure 6 and Figure 7 As shown, the dust container 20 is detachably disposed on the body 10 , and the dust inlet end 21 of the dust container 20 is connected to the dust inlet channel 11 , so as to collect dust entering from the dust inlet channel 11 .

[0085] The fan assembly 40 is disposed on the body 10, and the air inlet 41 of the fan assembly 40 is connected to the airflow outlet end 22 of the dust bucket 20. The fan assembly 40 generates negative pressure to ensure that the dust in the dust box can enter the dust inlet channel 11 through the dust inlet 111 and allow the airflow to flow. The dust in the dust box here includes the debris in the dust box.

[0086] Specifically, when the cleaning robot moves to the main body 10, and the garbage inlet of the cleaning robot is connected to the dust inlet port 111 of the dust inlet channel 11, the fan assembly 40 is running, so that a seal is formed between the garbage inlet of the cleaning robot and the dust inlet port 111 of the dust inlet channel 11, thereby sucking the dust in the dust box into the dust inlet channel 11.

[0087] After the cleaning robot moves into position, the dust collecting pile in this embodiment can suck the dust in the dust box into the dust bin 20 for collection through the operation of the fan assembly 40, and finally the air flow is discharged by the fan assembly 40, so as to recover the dust in the dust box of the cleaning robot into the dust bin 20, and the entire dust cleaning process can be automated.

[0088] It should be noted that the dust bin 20 is detachably disposed on the main body 10 , thereby facilitating the cleaning and replacement of the dust bin 20 .

[0089] In one embodiment, Figure 5 and Figure 6 As shown, the body 10 includes a base 101 and a mounting body 102. A dust inlet channel 11 is formed in the base 101, and a dust inlet port 111 is disposed at the top of the base 101. The cleaning robot moves to the base 101 to clean dust.

[0090] The installation body 102 is connected to the base 101, and an air intake duct 80 is provided in the installation body 102. Figure 7As shown, the air intake duct 80 connects the dust intake channel 11 and the dust intake end 21 , so that dust enters the dust barrel 20 from the dust intake channel 11 through the air intake duct 80 .

[0091] Optionally, the dust container 20 is detachably disposed on the installation body 102. The fan assembly 40 is disposed on the installation body 102.

[0092] The cleaning robot enters the base 101 from the front end of the base 101 , and the installation body 102 is arranged at the rear end of the base 101 , so that the cleaning robot will not collide with the installation body 102 during the movement.

[0093] In some embodiments, the mounting body 102 and the base 101 may be an integrated structure, where the integrated structure may be integrally formed or may be formed by connecting and fixing two independent components to form an integral structure.

[0094] In some embodiments, the installation body 102 is detachably connected to the base 101, that is, the installation body 102 can be separated from the base 101 before use to facilitate transportation and storage. When in use, the installation body 102 is connected to the base 101 by fasteners or snap-on connection or other connection methods in related technologies.

[0095] Optionally, the air intake duct 80 may be connected to the base 101, that is, after the installation body 102 is separated from the base 101, the air intake duct 80 is connected to the base 101. Alternatively, the air intake duct 80 may be connected to the installation body 102, that is, after the installation body 102 is separated from the base 101, the air intake duct 80 is connected to the installation body 102. Alternatively, the air intake duct 80 may be separated from the base 101 and the installation body 102. In some embodiments, it is not excluded that the air intake duct 80 is integrated on the base 101 or the installation body 102.

[0096] In one embodiment, Figure 8 and Fig. 9 As shown, the dust collecting pile further includes a first filter assembly 30. The first filter assembly 30 is arranged above the fan assembly 40.

[0097] The air inlet end 31 of the first filter assembly 30 is connected to the air flow outlet end 22 of the dust container 20 to filter the air flow discharged through the dust container 20 .

[0098] The air outlet 32 ​​of the first filter assembly 30 is connected to the air inlet 41 of the fan assembly 40. When the cleaning robot moves to the body 10, and the garbage inlet of the cleaning robot is connected to the dust inlet 111 of the dust inlet channel 11, the fan assembly 40 generates negative pressure during operation, which can suck the dust in the dust box into the dust barrel 20 for collection, and filter the dust through the first filter assembly 30 before the airflow enters the fan assembly 40, thereby preventing the dust from entering the fan assembly 40. Finally, the airflow is discharged by the fan assembly 40, so as to realize the recovery of the dust in the dust box of the cleaning robot into the dust barrel 20, and the entire dust cleaning process can be automated.

[0099] The first filter assembly 30 is located above the fan assembly 40, that is, the airflow discharged from the dust bin 20 needs to be filtered by the first filter assembly 30 first, and then flow into the air inlet 41 of the fan assembly 40 from the bottom of the first filter assembly 30, so that the flow path distribution of the airflow is more reasonable, and can ensure a more reasonable distribution of components and effectively utilize the height space.

[0100] The first filter assembly 30 may be directly disposed on the body 10 , or the first filter assembly 30 may be directly disposed on the fan assembly 40 .

[0101] In some embodiments, the first filter assembly 30 is disposed on the installation body 102 , that is, after the installation body 102 is separated from the base 101 , the dust bin 20 , the first filter assembly 30 and the fan assembly 40 can all be separated from the base 101 along with the installation body 102 .

[0102] Optionally, the first filter assembly 30 may be detachably disposed on the installation body 102 , or the first filter assembly 30 may also be fixed on the installation body 102 .

[0103] In one embodiment, Fig.10 As shown, the body 10 further includes: a first mounting portion 13 and a second mounting portion 14. The first mounting portion 13 and the second mounting portion 14 are used to mount the dust bucket 20 and the first filter assembly 30 respectively. The first mounting portion 13 and the second mounting portion 14 are disposed on the mounting body 102.

[0104] A first detection member is provided between the dust bin 20 and the first mounting portion 13, and is used to detect whether the dust bin 20 and the first mounting portion 13 are properly installed. For example, when the dust bin 20 and the first mounting portion 13 are properly installed, the first detection member may send a first signal.

[0105] A second detection member is provided between the first filter assembly 30 and the second mounting portion 14, and the second detection member is used to detect whether the first filter assembly 30 and the second mounting portion 14 are installed in place. For example, when the first filter assembly 30 and the second mounting portion 14 are installed in place, the second detection member can send a second signal.

[0106] The dust collecting pile also includes a control unit, which is connected to the first detection member or the second detection member by signal, and is connected to the fan assembly 40 by signal, and the first detection member is connected to the second detection member by signal, so that when at least one of the dust bin 20 and the first filter assembly 30 is not installed in place, the control unit cannot start the fan assembly 40, that is, the first detection member and the second detection member are in a series relationship, so the control unit can only start the fan assembly 40 when the first detection member sends a first signal and the second detection member sends a second signal. For example, the first detection member can be connected to the control end of the second detection member, and the signal transmitting end of the second detection member is connected to the control unit. If the control end of the second detection member cannot receive the first signal sent by the first detection member, even if the first filter assembly 30 and the second mounting portion 14 are installed in place, the second detection member cannot send a start signal (such as the second signal) to the control unit.

[0107] In this embodiment, by connecting the first detection component and the second detection component in series, the relationship between the dust bin 20 in-place detection and the first filter assembly 30 in-place detection can be achieved. That is, if the dust bin 20 is not in place or the first filter assembly 30 is not in place or both are not in place, the control unit can identify them as not in place (that is, the control unit determines that the dust collecting pile is not installed in place), thereby reducing electrical connection components and identification components.

[0108] In one embodiment, the dust bin 20 is detachably connected to the first mounting portion 13 , so as to facilitate cleaning and replacement of the dust bin 20 .

[0109] It should be noted that the dust bin 20 and the first mounting portion 13 can be snap-connected, such as the cooperation between a protrusion and a slide, or a mounting groove can be formed on the first mounting portion 13, and at least part of the dust bin 20 is located in the mounting groove. This is not limited here and can be selected according to actual needs, as long as it is easy to install and will not fall off at will.

[0110] In one embodiment, the first filter assembly 30 is detachably connected to the second mounting portion 14 , thereby facilitating replacement and cleaning of the first filter assembly 30 , thereby improving the filtering capacity of the first filter assembly 30 .

[0111] It should be noted that the first filter assembly 30 and the second mounting portion 14 can be snap-fitted, such as the cooperation of a protrusion and a slideway, or a mounting groove can be formed on the second mounting portion 14, and at least part of the first filter assembly 30 is located in the mounting groove. This is not limited here and can be selected according to actual needs, as long as it is easy to install and will not fall off at will. In this embodiment, the second mounting portion 14 has a mounting cavity, and the first filter assembly 30 is located in the mounting cavity, and a sealed connection is formed between the upper part of the first filter assembly 30 and the body 10, and a second channel 18 is provided on the body 10, and the second channel 18 connects the air outlet 32 ​​of the first filter assembly 30 and the air inlet 41 of the fan assembly 40, so as to ensure that the airflow discharged through the first filter assembly 30 enters the air inlet 41 of the fan assembly 40 only through the second channel 18.

[0112] In one embodiment, the dust container 20 includes a dust bag 23 or a cyclone separator 24. The dust container 20 can collect garbage through the dust bag 23 or the cyclone separator 24. The dust bag can be a paper bag or a cloth bag with good air permeability and dustproof effect, which can be easily replaced.

[0113] It should be noted that the cyclone separator 24 can be a cyclone separator known in the relevant technology. The working principle of the cyclone separator is the rotational motion caused by the tangential introduction of the airflow. When the particles rotate at high speed in the airflow, the centrifugal force is much greater than the gravity, and the greater the speed, the greater the centrifugal sedimentation velocity obtained by the particles. When the solid particles enter the conical cylinder with the gas from the tangential direction and rotate in the cylinder, the airflow collides with the wall of the device, and the particles hit the wall of the tube and rotate down, thereby achieving the purpose of separating the solid and the gas. In this embodiment, the gas finally enters the air inlet end 31 of the first filter component 30 through the airflow outlet end 22 of the dust bin 20.

[0114] Optionally, the dust bag 23 can be installed on the dust bucket 20 with the cyclone separator 24 through the dust bag adapter 25 to meet the different needs of users. That is, the dust bag adapter 25 is similar to a bracket, which is mainly used to install the dust bag 23 on the dust bucket 20, and the specific structure is similar to the component used by the cyclone separator 24 to connect with the dust bucket 20. It is not limited here, as long as it can be connected with the dust bucket 20. In fact, it is similar to a component set up in the same way as the connection structure of the cyclone separator 24. Optionally, the dust bag 23 can be provided with an adapter 231 for connecting with the dust bag adapter 25, as shown in FIG. Fig.11 shown.

[0115] In one embodiment, the first mounting portion 13 can be selectively mounted with a dust bucket 20 including a dust bag or a dust bucket 20 including a cyclone separator. That is, the external structure of the dust bucket 20 can be a universal structure, the structure connected to the first mounting portion 13 adopts a unified structure, and the interior thereof can be a dust bag or a cyclone separator, so that the first mounting portion 13 can be selectively mounted with a dust bucket 20 including a dust bag or a dust bucket 20 including a cyclone separator.

[0116] In one embodiment, the first mounting portion 13 and the second mounting portion 14 are spaced apart so that the dust bucket 20 or the first filter assembly 30 can be installed on the main body 10 first, or the dust bucket 20 and the first filter assembly 30 can be installed on the main body 10 at the same time, that is, the installation of the dust bucket 20 and the first filter assembly 30 is not limited by the installation order, and can be installed and disassembled at will according to needs without interference between components, thereby simplifying the structure and facilitating installation.

[0117] The first mounting portion 13 and the second mounting portion 14 can be distributed on both sides of the base 101 in sequence, and after the dust bin 20 is installed on the first mounting portion 13, two structures with similar structural appearances are formed above the base 101, and the first filter assembly 30 is installed inside the first mounting portion 13.

[0118] In one embodiment, the first detection member is a contact detection element or a non-contact detection element; the second detection member is a contact detection element or a non-contact detection element.

A contact switch sensing element is provided on the first mounting portion 13, and a contact switch matching element is provided on the dust bucket 20. The contact switch sensing element can be matched with the contact switch matching element when the dust bucket 20 is mounted to the first mounting portion 13, so that the contact switch sensing matching element can sense the contact switch sensing element. A non-contact sensing element is provided on the second mounting portion 14, and a non-contact sensing matching element is provided on the first filter assembly 30. The non-contact sensing matching element can be matched with the non-contact sensing element when the first filter assembly 30 is mounted to the second mounting portion 14, so that the non-contact sensing matching element can sense the non-contact sensing element.

[0120] It should be noted that the contact detection element can be a contact sensor in the relevant technology, such as a pressure sensor, a switch element, etc., and the non-contact detection element can be a non-contact sensor in the relevant technology, such as a laser sensor, an inductive proximity sensor, etc.

[0121] In some embodiments, Fig.12and Fig.13 As shown, the contact detection element includes: a switch 131, which is arranged on the first mounting portion 13; a detection button 132, which is arranged opposite to the switch 131, so that when the dust bin 20 and the first mounting portion 13 are installed in place, the detection button 132 presses the switch 131 to be in a closed state, that is, after the dust bin 20 is installed in place, the switch 131 is in a closed state to output a corresponding signal.

[0122] The switch 131 may be a conventional button connected to the circuit. Only when the detection button 132 is pressed into place, the button can be turned on, thereby realizing the conduction of the circuit and signal transmission.

[0123] Optionally, the detection button 132 may be disposed on the dust container 20 .

[0124] Optionally, the contact detection element further includes: an elastic member 133, the elastic member 133 is arranged on the first mounting portion 13, and the detection button 132 is inserted into the elastic member 133; wherein the elastic member 133 is located between the detection button 132 and the first mounting portion 13, so that when the dust bucket 20 is separated from the first mounting portion 13, the elastic member 133 drives the detection button 132 to release the switch 131, so that the switch 131 is in an open state. The detection button 132 can be arranged on the first mounting portion 13, and it moves downward by relying on the pressure of the dust bucket 20, and when the dust bucket 20 is separated from the first mounting portion 13 upward, the detection button 132 can move upward under the drive of the elastic member 133, so as to release the switch 131. The bottom end of the detection button 132 has a limiting structure, so as to prevent the detection button 132 from being separated from the first mounting portion 13.

[0125] In some embodiments, the switch 131 is disposed on the second mounting portion 14, and the detection button 132 is disposed opposite to the switch 131, so that when the first filter component 30 and the second mounting portion 14 are installed in place, the detection button 132 presses the switch 131 to be in a closed state, that is, after the first filter component 30 is installed in place, the switch 131 is in a closed state to output a corresponding signal.

[0126] Optionally, the detection button 132 may be disposed on the first filter assembly 30 .

[0127] Optionally, the detection button 132 is arranged on the second mounting portion 14, the elastic member 133 is arranged on the second mounting portion 14, and the detection button 132 is passed through the elastic member 133; wherein, the elastic member 133 is located between the detection button 132 and the second mounting portion 14, so that when the first filter component 30 is detached from the second mounting portion 14, the elastic member 133 drives the detection button 132 to release the switch 131, so that the switch 131 is in an open state.

[0128] In some embodiments, the elastic member 133 may be a spring.

[0129] In one embodiment, Fig.14 and Fig.15 As shown, the first filter assembly 30 includes: a top cover 35, the top cover 35 has an air inlet channel 351, the air inlet channel 351 connects the air inlet end 31 and the connecting pipe 17; a filter part 34, the filter part 34 is arranged on the top cover 35, and is arranged opposite to the air outlet end 32, so that dust is filtered through the filter part 34 to prevent dust from entering the fan assembly 40.

[0130] Optionally, the filter part 34 may be a filter structure in the related art, such as a filter mesh structure. The specific structure may be, for example, a circular mesh structure, so as to filter dust.

[0131] Optional, such as Fig.15 As shown, the filter part 34 is a bagged structure, that is, the filtering area of ​​the filter part 34 is increased, and the filtering contact area is increased, thereby improving the filtering effect. Due to the increase in the filtering area, the service life of the filter part 34 will be greatly increased, thereby reducing the replacement frequency of the filter part 34.

[0132] It should be noted that the bagged structure can be connected so that the filter part 34 has a containing space, and the airflow enters the containing space and is then discharged from the filter part 34 .

[0133] Combination Fig.15 As shown, the first filter assembly 30 further includes: a dust holding member 33, the dust holding member 33 has an air inlet end 31 and an air outlet end 32, and the dust holding member 33 is arranged in the filter portion 34, and the filter portion 34 is arranged opposite to the air outlet end 32, so that the airflow discharged through the air outlet end 32 passes through the filter portion 34 and then enters the air inlet 41 of the fan assembly 40. The dust holding member 33 can absorb dust in the airflow, that is, it realizes the primary absorption of dust in the airflow, and prevents a large amount of dust from entering the filter portion 34 and clogging the filter portion 34.

[0134] In one embodiment, the dust holding member 33 includes dust holding cotton. After entering the first filter assembly 30, the airflow will first pass through the dust holding cotton, which cannot intercept all dust within the specification, but can intercept some larger particles, reducing the risk of the filter part 34 being blocked, thereby increasing the service life of the entire first filter assembly 30.

[0135] Optionally, the dust container 33 includes a sponge. The filter portion 34 may be a filter screen, and the filter screen may include filter cotton.

[0136] In one embodiment, Fig.15As shown, the air inlet end 31 and the air outlet end 32 are both located on the outer surface of the dust holding member 33, and the area of ​​the air inlet end 31 is smaller than the area of ​​the air outlet end 32, so that the airflow can enter the dust holding member 33 from a relatively small surface, thereby increasing the path length of the airflow through the dust holding member 33, thereby increasing the amount of dust absorbed and further reducing the impact of dust on the filter part 34.

[0137] In one embodiment, the filter portion 34 wraps the dust holding piece 33. The filter portion 34 can not only fix the dust holding piece 33, but also allow the airflow flowing out of the dust holding piece 33 to be discharged directly through the filter portion 34, thereby ensuring the filtering effect and simplifying the structure.

[0138] In one embodiment, the dust holding member 33 and the filter portion 34 are disposed on the top cover 35 , so that the dust holding member 33 and the filter portion 34 are fixed to the top cover 35 .

[0139] Specifically, the top cover 35 of the first filter assembly 30 may be connected to the body 10 , so that the first filter assembly 30 is disposed on the body 10 .

[0140] Optionally, at least one of the dust holding member 33 and the filter portion 34 can be directly fixed to the top cover 35, that is, the dust holding member 33 can be connected to the top cover 35, and the filter portion 34 can be wrapped on the dust holding member 33, that is, the filter portion 34 is connected to the dust holding member 33, and the filter portion 34 may not be directly connected to the top cover 35.

[0141] Optionally, the filter part 34 is connected to the top cover 35 to form a receiving space between the filter part 34 and the top cover 35 , and the dust holding member 33 is located in the receiving space, that is, the dust holding member 33 is fixed in the receiving space formed between the filter part 34 and the top cover 35 .

[0142] In one embodiment, the filter part 34 is detachably disposed on the top cover 35, so as to facilitate replacement of the filter part 34 and the dust container 33. The filter part 34 and the top cover 35 can be connected by snap connection, bonding or by fasteners, which is not limited here, as long as it is convenient for disassembly and assembly.

[0143] In one embodiment, the area of ​​the dust holding piece 33 covered by the top cover 35 is smaller than the area of ​​the dust holding piece 33 covered by the filter portion 34, so that the air inlet end 31 of the dust holding piece 33 is smaller than the air outlet end 32, thereby ensuring that the airflow flows out quickly and the dust holding piece 33 absorbs dust to the greatest extent.

[0144] In one embodiment, Fig.16 and Fig.17 As shown, the fan assembly 40 includes a housing 43 , a fan 44 and a flexible member 45 .

[0145] The housing 43 is arranged on the body 10, and the flexible member 45 is located between the housing 43 and the fan 44. The fan 44 is fixed in the housing 43 through the flexible member 45, and the flexible member 45 prevents the fan 44 from directly contacting the housing 43. The arrangement of the flexible member 45 can prevent the fan 44 from directly contacting the housing 43, thereby preventing a large noise, and since the fan 44 is fixed in the housing 43 through the flexible member 45, the housing 43 can be adapted to different types of fans 44 by simply replacing the flexible member 45, thereby improving the versatility of the housing 43.

[0146] Specifically, the body 10 is formed with an installation cavity, and the fan assembly 40 and the first filter assembly 30 are both arranged in the installation cavity, and a partition is provided between the fan assembly 40 and the first filter assembly 30, and a second channel 18 is provided on the partition, and the second channel 18 is connected to the air outlet 32 ​​of the first filter assembly 30 and the air inlet 41 of the fan assembly 40, so as to ensure that the airflow discharged through the first filter assembly 30 enters the air inlet 41 of the fan assembly 40 only through the second channel 18, as shown in the specific Fig. 9 and Fig.10 The body 10 protects the fan assembly 40 and the first filter assembly 30, and prevents the fan assembly 40 and the first filter assembly 30 from being exposed to the external environment.

[0147] The fan assembly 40 in this embodiment avoids hard contact between the housing 43 and the fan 44 by positioning the flexible member 45 between the housing 43 and the fan 44, thereby avoiding the generation of loud noise. Furthermore, since the housing 43 and the fan 44 are not directly connected, fans 44 of different sizes can be installed in the housing 43 according to usage requirements, thereby improving the versatility of the housing 43.

[0148] In one embodiment, Fig.16 and Fig.17 As shown, the shell 43 includes: a first shell member 431; a second shell member 432, and the second shell member 432 is detachably connected to the first shell member 431 to release or fix the fan 44 and the flexible member 45, which not only facilitates the installation of the fan 44 and the flexible member 45, but also allows subsequent maintenance and replacement. Different types of fans 44 can be selected to replace the original type of fan 44, and only the flexible member 45 needs to be adaptively replaced, thereby realizing the universality of the shell 43.

[0149] In some embodiments, the second housing member 432 is sealedly connected to the first housing member 431 , and the second housing member 432 and the first housing member 431 may be connected by a plurality of fasteners.

[0150] In one embodiment, Fig.17As shown, the flexible member 45 includes: a first flexible portion 451, which is arranged between the fan 44 and the first housing member 431 to support the fan 44; and a second flexible portion 452, at least part of which is arranged between the fan 44 and the second housing member 432 to clamp the fan 44 with the first flexible portion 451. The second flexible portion 452 can be filled between the fan 44 and the second housing member 432, so as to prevent the fan 44 from moving relative to the second housing member 432 and ensure that the fan 44 is fixed in the second housing member 432, while the first flexible portion 451 can be filled between the fan 44 and the first housing member 431, so as to prevent the fan 44 from moving relative to the first housing member 431 and ensure that the fan 44 is fixed in the first housing member 431. The first flexible portion 451 and the first flexible portion 451 realize the fixation of the fan 44 and completely avoid the hard contact between the fan 44 and the housing 43.

[0151] Optionally, the first flexible portion 451 and the second flexible portion 452 may be connected.

[0152] Optionally, the first flexible portion 451 and the second flexible portion 452 are independently arranged, that is, during the specific installation, the first flexible portion 451 and the fan 44 can be first arranged in the first shell member 431, and then the second flexible portion 452 and the second shell member 432 can be snapped onto the fan 44 and the first shell member 431, and the second shell member 432 can be fixed to the first shell member 431, so as to complete the installation of the fan assembly 40.

[0153] In one embodiment, part of the second flexible portion 452 is clamped between the first shell member 431 and the second shell member 432 to seal the gap between the first shell member 431 and the second shell member 432, thereby avoiding the use of other seals to seal the first shell member 431 and the second shell member 432. The structure is relatively simple and the installation steps can be reduced.

[0154] In one embodiment, the first flexible portion 451 is a rubber pad, and the second flexible portion 452 is a rubber sleeve. The rubber pad is supported between the fan 44 and the first housing 431, and the rubber sleeve is sleeved on the upper part of the fan 44 to protect the fan 44.

[0155] In one embodiment, the second housing 432 is provided with an air flow hole 433, the air flow hole 433 is connected to the air inlet 41 of the fan 44, and there is a gap between the first housing 431 and the fan 44; wherein an exhaust passage 46 is formed between the first flexible portion 451, the second flexible portion 452, the first housing 431 and the fan 44, and the exhaust passage 46 is connected to the air outlet 42 of the fan 44. The airflow discharged from the first filter assembly 30 enters the air inlet 41 of the fan 44 through the air flow hole 433, and is discharged into the exhaust passage 46 through the air outlet 42 of the fan 44, and is finally discharged from the exhaust passage 46, thereby realizing the circulation of the airflow.

[0156] like Fig.18 As shown, the first housing 431 has a space 4311 for accommodating the fan 44, and a plurality of air holes 4312 are provided on the side wall of the space 4311, that is, the airflow in the exhaust channel 46 is discharged through the air holes 4312, and the air holes 4312 occupy the circumferential direction of the first housing 431, so that the airflow can circulate in the exhaust channel 46. The first housing 431 has housing members sleeved on both sides, and the airflow space formed between the housing members sleeved on both sides is connected to the exhaust channel 46 through the air holes 4312, and finally discharged from the fan assembly 40.

[0157] In one embodiment, the fan assembly 40 further includes an exhaust hole 434 , which is in communication with the exhaust passage 46 , so as to discharge the airflow in the exhaust passage 46 out of the fan assembly 40 .

[0158] Optionally, the exhaust hole 434 is provided on the housing 43 to discharge the airflow in the exhaust channel 46. Specifically, the exhaust hole 434 can be provided on the first housing member 431, that is, the airflow in the exhaust channel 46 can be discharged from the fan assembly 40 without opening a hole in the second flexible portion 452. The exhaust hole 434 can also be provided on the second housing member 432, that is, a hole can be opened on the second flexible portion 452 so that the exhaust hole 434 is connected to the exhaust channel 46. There is no limitation on the specific position of the exhaust hole 434, as long as the airflow can be discharged from the exhaust channel 46.

[0159] In one embodiment, Fig.16 As shown, the fan assembly 40 further includes a muffler 47, which is disposed on the housing 43, and the inlet of the muffler 47 is connected to the exhaust hole 434, or the outlet of the muffler 47 is connected to the exhaust hole 434. That is, the airflow discharged from the exhaust channel 46 is silenced by the muffler 47, thereby reducing the noise caused by the airflow.

[0160] Optionally, the muffler 47 can be arranged inside the shell 43, and the exhaust channel 46 is connected to the inlet of the muffler 47, and the outlet of the muffler 47 can be connected to the exhaust hole 434, so that the air flow passes through the muffler 47 before being discharged from the shell 43.

[0161] Optionally, the muffler 47 can be arranged outside the shell 43, and the exhaust channel 46 is connected to the exhaust hole 434, and the exhaust hole 434 is connected to the inlet of the muffler 47, so that the airflow is first discharged from the shell 43 and then silenced by the muffler 47.

[0162] In one embodiment, the exhaust passage 46 is arranged around the circumferential outer surface of the fan 44, and the length of the exhaust passage 46 extending along the circumferential outer surface of the fan 44 is greater than the length of the exhaust hole 434 extending along the circumferential outer surface of the fan 44, that is, the airflow exhausted by the fan 44 is only discharged from the outside of the shell 43 through a relatively fixed position, so that the airflow can rotate nearly one circle in the exhaust passage 46 and then be discharged from the exhaust hole 434, thereby reducing noise by extending the airflow path.

[0163] Specifically, the circumferential outer surface of the fan 44 can form nearly a circle of air outlets 42, and the exhaust channel 46 also forms a nearly a circle of surrounding space, so that the airflow of the air outlet 42 at each position can be directly discharged into the exhaust channel 46. At this time, the exhaust hole 434 on the shell 43 can be located in the circumferential direction of the shell 43, or the exhaust hole 434 on the shell 43 can be set at the top of the shell 43. At this time, the exhaust channel 46 can be connected to the exhaust hole 434 through a pipeline, so as to ensure that the airflow discharged from the exhaust channel 46 needs to be rotated to a relatively fixed position for discharge, thereby reducing noise by increasing the airflow path.

[0165] In some embodiments, the second filter component 50 can be a conventional filter structure, that is, it can include a filter net to achieve secondary filtration of the airflow to ensure that the discharged airflow is clean. For example, the second filter component 50 can be an annular structure, that is, a circumferentially closed structure, which is arranged around the first filter component 30. The airflow enters the fan component 40 from the first filter component 30 and flows from top to bottom, and then the airflow enters the second filter component 50 from the fan component 40 and flows from bottom to top.

[0166] In some embodiments, Fig.19 As shown, the second filter assembly 50 is provided with an opening 53, that is, the second filter assembly 50 can be a circumferentially non-closed structure.

The corresponding space in the opening 53 is used to form a space for arranging the connecting pipe 17 and the intake duct 80.

[0171] In some embodiments, Figure 20 to Figure 22 As shown, the second filter assembly 50 includes a frame 54 and a filter screen 55. The filter screen 55 is arranged on the frame 54. The filter screen 55 is formed with an escape groove 56. The escape groove 56 includes a first opening 561, a second opening 562 and a third opening 563.

[0182] When the dust in the dust box enters the dust inlet channel 11, it is necessary to ensure that the dust inlet channel 11 forms a negative pressure environment, so the shielding member 90 closes the liquid outlet hole 12 to ensure that the dust inlet channel 11 is not connected to the outside. When the dust in the dust box stops entering the dust inlet channel 11, the shielding member 90 can be opened to connect the dust inlet channel 11 to the outside, and the liquid entering the dust inlet channel 11 can be discharged from the dust inlet channel 11 through the liquid outlet hole 12, thereby ensuring that the dust inlet channel 11 is dry to the greatest extent.

[0183] It should be noted that the above-mentioned outside world can be connected to the external environment space, or it can be other spaces independent of the dust inlet channel 11. For example, a liquid collector can be provided to enable the liquid in the dust inlet channel 11 to flow into the liquid collector. At this time, the space formed by the liquid collector can also be understood as the outside world.

[0184] In some embodiments, the shielding member 90 is movably disposed on the body 10, and the shielding member 90 can be driven to move by a driving mechanism, so as to achieve the closing and releasing of the liquid outlet 12. Specifically, the driving mechanism can be a pneumatic cylinder, an oil cylinder or an electric cylinder, and the telescopic rod of the driving mechanism can drive the shielding member 90 to move relative to the liquid outlet 12, so as to achieve the closing and releasing of the liquid outlet 12. Alternatively, the driving mechanism can include a motor, and the motor drives the shielding member 90 to rotate relative to the body 10, so as to achieve the closing and releasing of the liquid outlet 12.

[0185] It should be noted that when the fan assembly 40 is running, that is, the dust in the dust box starts to be cleaned, and the shielding member 90 can be rotated from the open position to the sealed position. Specifically, the control unit of the dust collecting pile can control the above-mentioned driving mechanism to drive the shielding member 90 to move from the open position to the sealed position before controlling the operation of the fan assembly 40, or the control unit can control the operation of the fan assembly 40 and the above-mentioned driving mechanism at the same time. When the fan assembly 40 stops running, that is, the dust in the dust box stops being cleaned, and the shielding member 90 can be rotated from the sealed position to the open position. Specifically, the control unit of the dust collecting pile can control the above-mentioned driving mechanism to drive the shielding member 90 to move from the sealed position to the open position after controlling the fan assembly 40 to stop running, or the control unit can control the above-mentioned driving mechanism to operate while controlling the fan assembly 40 to stop running.

[0186] In some embodiments, the shielding member 90 can be connected to the body 10, and the movement of the shielding member 90 does not rely on the driving mechanism. The shielding member 90 can be rotated from the open position to the sealed position under the drive of the fan assembly 40, that is, when the fan assembly 40 is running, the shielding member 90 can be driven to move from the open position to the sealed position by the negative pressure generated by the fan assembly 40. When the fan assembly 40 stops running, the shielding member 90 can be rotated from the sealed position to the open position under the action of gravity.

[0187] Optionally, the shielding member 90 may be disposed on a plate, and the plate may be rotatably disposed on the main body 10, thereby ensuring that the shielding member 90 rotates from the sealing position to the opening position under the action of gravity.

[0188] In one embodiment, the liquid outlet 12 is connected to the side of the dust inlet channel 11 close to the dust bin 20, that is, when the fan assembly 40 is running, since the liquid will flow from the dust inlet port 111 along the dust inlet channel 11 to the dust bin 20, after the fan assembly 40 stops running, most of the liquid is concentrated on the side close to the dust bin 20. At this time, opening the liquid outlet 12 can easily allow the liquid to flow out of the liquid outlet 12.

[0189] In one embodiment, Fig.24As shown, a sealing groove 19 is provided on the main body 10 , and one end of the liquid outlet 12 is located in the sealing groove 19 . When the shielding member 90 is in the sealing position, the shielding member 90 is located in the sealing groove 19 , and at this time, the shielding member 90 can reliably seal the liquid outlet 12 .

[0190] Optionally, when the shielding member 90 is located at the sealing position, the shielding member 90 can be matched with the side wall clearance of the sealing groove 19 , but can be reliably stopped on the liquid outlet 12 , thereby achieving sealing of the liquid outlet 12 .

[0191] Optionally, when the shielding member 90 is located at the sealing position, the shielding member 90 may be interference fit with the side wall of the sealing groove 19 , that is, the shielding member 90 seals the sealing groove 19 , thereby achieving sealing of the liquid outlet 12 .

[0192] It should be noted that the sealing groove 19 can be arranged on a side of the liquid outlet 12 close to the dust inlet channel 11, that is, the sealing groove 19 is located in the dust inlet channel 11, and the shielding member 90 can be driven to move by a driving mechanism.

[0193] Alternatively, the sealing groove 19 can be arranged on the side of the liquid outlet 12 away from the dust inlet channel 11, that is, the sealing groove 19 is located outside the dust inlet channel 11. At this time, the shielding member 90 can be driven to move by the fan assembly 40, and the shielding member 90 can be separated from the sealing groove 19 under the action of gravity.

[0194] In one embodiment, the shielding member 90 is disposed on a plate body, and when the fan assembly 40 is not working, the shielding member 90 is separated from the sealing groove 19 under the action of its own gravity. Only when the fan assembly 40 is working can the plate body be driven to rotate, so that the shielding member 90 is located in the sealing groove 19, thereby achieving sealing of the liquid outlet 12.

[0195] In one embodiment, the shielding member 90 is rotatably disposed on the body 10 so that the shielding member 90 can be switched between a sealing position and an open position. The shielding member 90 can be rotated relative to the body 10 by a driving mechanism to seal or release the liquid outlet 12. Alternatively, the shielding member 90 can be rotated under the action of the fan assembly 40 and can be rotated from the sealing position to the open position under the action of gravity.

[0196] In one embodiment, the shielding member 90 is disposed on a side of the body 10 away from the dust inlet passage 11 , that is, the shielding member 90 can rotate from the sealing position to the opening position under the action of gravity.

[0197] In one embodiment, at least part of the shielding member 90 is a flexible member, which not only has strong structural stability, but also can well seal the liquid outlet 12. Optionally, at least part of the shielding member 90 is rubber, and the shielding member 90 can be a soft film. When the fan assembly 40 is running and generates negative pressure to suck up the soft film, the liquid outlet 12 is blocked and a sealing effect is achieved. When the fan assembly 40 is not working, the soft film returns to its original position, and the liquid can flow out of the dust inlet channel 11 through the liquid outlet 12, thereby avoiding a large amount of liquid remaining in the dust inlet channel 11.

[0198] In some embodiments, the liquid outlet hole 12 can be a circular hole, a triangular hole or a rectangular hole, and of course the liquid outlet hole 12 can also be a special-shaped hole, which is not limited here. The specific structural shape of the sealing groove 19 for accommodating the shielding member 90 can also be circular, triangular or rectangular, and of course the sealing groove 19 can also be a special-shaped groove.

[0199] In one embodiment, there are multiple liquid outlet holes 12 to increase the rate at which the liquid flows out and ensure that the liquid in the dust inlet channel 11 can flow out reliably.

[0200] Optionally, there is at least one shielding member 90, and one shielding member 90 can shield multiple liquid outlet holes 12, thereby simplifying the structure.

[0201] Optionally, there are multiple shielding members 90, and the multiple shielding members 90 are arranged corresponding to the multiple liquid outlet holes 12 one by one, so as to ensure that each shielding member 90 independently seals each liquid outlet hole 12, thereby increasing the reliability of the sealing.

[0202] In one embodiment, Fig. 9 As shown, the dust collecting pile also includes: a spoiler 60, which is arranged around the second filter component 50, and the spoiler 60 is arranged opposite to the air outlet surface 52 of the second filter component 50 to form a spoiler channel 61; wherein, an air outlet channel 62 is formed between the spoiler 60 and the main body 10, and the bottom end of the spoiler channel 61 is connected to the bottom end of the air outlet channel 62, that is, the airflow discharged from the air outlet surface 52 of the second filter component 50 can flow downward under the obstruction of the spoiler 60, and flow into the air outlet channel 62 from the bottom of the spoiler channel 61, thereby increasing the airflow path, thereby achieving the effect of noise reduction.

[0203] Specifically, Fig. 9 As shown, the spoiler 60 includes a first surface 63 and a second surface 64 relative to each other. The first surface 63 is arranged opposite to the air outlet surface 52 of the second filter component 50 to form a spoiler channel 61, and the second surface 64 is arranged opposite to the body 10 to form an air outlet channel 62; wherein, the bottom end of the spoiler channel 61 is connected to the bottom end of the air outlet channel 62, so that the airflow discharged from the air outlet surface 52 can enter the air outlet channel 62 from the bottom end of the spoiler channel 61, thereby increasing the airflow path.

[0204] In one embodiment, at least one of the body 10 and the second filter assembly 50 is connected to the spoiler 60 to fix the spoiler 60, that is, to ensure that the spoiler 60 can guide the flow stably.

[0205] In one embodiment, the upper side of the spoiler 60 is connected to at least one of the main body 10 and the second filter assembly 50 to avoid direct connection between the top of the spoiler channel 61 and the top of the air outlet channel 62, so that the airflow cannot flow directly from the top of the spoiler channel 61 into the air outlet channel 62.

[0206] Optionally, the spoiler 60 may be connected to the body 10 , so that the top end of the spoiler 60 forms a sealed connection with the body 10 .

[0207] Optional, combined Figure 25 to Figure 28 As shown, the top of the spoiler 60 is fixedly connected to the second filter assembly 50 , that is, the top of the spoiler 60 can be connected to the frame 54 of the second filter assembly 50 , so that the top of the spoiler 60 forms a sealed connection with the second filter assembly 50 .

[0208] In one embodiment, the bottom end of the spoiler 60 is suspended so that the bottom end of the spoiler channel 61 is connected to the bottom end of the air outlet channel 62, that is, the second filter assembly 50 and the main body 10 may not contact the bottom end of the spoiler 60, so that the airflow enters the air outlet channel 62 along the bottom end of the spoiler 60.

[0209] Optionally, the bottom end of the spoiler 60 may be lower than the bottom end of the air outlet surface 52 , that is, it is sufficient as long as it is ensured that the bottom end of the spoiler 60 and the body 10 do not form a sealed connection.

[0210] Optionally, the bottom end of the spoiler 60 is higher than the bottom end of the air outlet surface 52 , that is, part of the airflow discharged from the air outlet surface 52 may not be stopped by the spoiler 60 .

[0211] In one embodiment, Fig.28 As shown, a connecting channel 65 is provided on the spoiler 60, and the spoiler channel 61 is also connected to the air outlet channel 62 through the connecting channel 65, that is, the connecting channel 65 can directly allow part of the airflow to enter the air outlet channel 62, so that a large amount of airflow will not directly impact the spoiler 60. On the basis of ensuring that the flow path of part of the airflow is increased, the noise caused by the impact of the airflow can also be avoided.

[0212] In some embodiments, the connecting channel 65 is a through hole, and the through hole is located in the middle of the spoiler 60, that is, the spoiler channel 61 and the air outlet channel 62 are also connected through the through hole.

[0213] In some embodiments, the communication channel 65 is a notch, which is recessed upward from the bottom end of the spoiler 60 , that is, it can be understood that an opening is formed on the spoiler 60 for directly releasing the airflow.

[0214] In one embodiment, there are multiple connecting channels 65 , so as to ensure that airflows at different positions can directly enter the air outlet channel 62 through the connecting channels 65 .

[0215] In one embodiment, the air outlet surface 52 includes a curved surface, the spoiler 60 includes an arc-shaped plate arranged opposite to the curved surface, and a plurality of connecting channels 65 are arranged at intervals along the circumferential direction of the arc-shaped plate. The shape of the spoiler 60 is adapted to the air outlet surface 52, which can ensure reliable filtration and enable a reasonable structural layout.

[0216] In one embodiment, Figure 2 and Figure 6 As shown, the dust collecting pile further includes: an air outlet plate 70, which is arranged above the second filter assembly 50, and is provided with a through hole 71, which is connected to the top of the air outlet channel 62, that is, the airflow entering the air outlet channel 62 flows upward, and is discharged through the through hole 71 on the air outlet plate 70. Under the action of the spoiler 60, the airflow can be formed from top to bottom, and then discharged from bottom to top, so that the airflow path is greatly lengthened to achieve the purpose of noise reduction.

[0217] Optionally, the through hole 71 of the air outlet plate 70 can be directly connected to the air outlet surface 52 of the second filter component 50, that is, the spoiler 60 can be removed, and the airflow from the air outlet surface 52 of the second filter component 50 can be directly discharged from the through hole 71 of the air outlet plate 70.

[0218] like Figure 2 As shown, the dust collecting pile also includes a first charging contact piece 103, and the cleaning robot also includes a second charging contact piece. The first charging contact piece 103 is used to be electrically connected to the second charging contact piece so that the dust collecting pile can charge the cleaning robot. The first charging contact piece 103 can be set on the body 10. Further, the first charging contact piece 103 can be set on the base 101, and the first charging contact piece 103 and the dust inlet 111 are located on the same surface, and the first charging contact piece 103 and the dust inlet 111 are spaced apart.

[0219] In one embodiment, the plurality of first charging contact electrodes 103 and the plurality of second charging contact electrodes are arranged in pairs.

[0220] The cleaning robot needs to move to the main body 10 for subsequent dust box cleaning or charging.

[0221] Specifically, the cleaning robot can move along the body 10, that is, the cleaning robot can perform a pile-up movement, and the pile-up movement can be understood as when the distance between the cleaning robot and the body 10 is less than a certain threshold, for example, the cleaning robot has arrived near the body 10, and the cleaning robot will move in one direction more obviously. The forward direction of the pile-up movement can be understood as: in order to make the dust box discharge dust into the dust inlet channel 11, or the second charging contact electrode contact the first charging contact electrode 103, the cleaning robot moves from the first position point to the second position point, and the direction from the first position point to the second position point is the forward direction of the pile-up movement.
