Detailed Description

Embodiments of the present disclosure are described in detail below with reference to the attached drawing figures:

In order that the above-recited objects, features and advantages of the present disclosure will become more readily apparent, a more particular description of the disclosure will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. The present disclosure may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the disclosure, and therefore the disclosure is not to be limited to the specific embodiments disclosed below.

The cleaning robot system of the present embodiment includes a cleaning robot 10, and the cleaning robot 10 walks and works in a work area;

In an implementation manner of the present disclosure, the cleaning robot 10 includes a housing, a moving module disposed at a bottom of the housing for driving the cleaning robot 10 to travel on a working surface, an energy supply unit (e.g., a battery pack) disposed on the housing, and a control module disposed on the housing and electrically connected with the energy supply unit. The cleaning module is typically provided at the bottom of the housing to perform cleaning tasks. The moving module includes at least one wheel 103 provided at the bottom of the robot housing, and a motor that drives the wheel 103 to rotate.

The cleaning module may include a dust suction port provided at the bottom of the housing, and a dust box assembly 110 provided in the housing, and the roller brush 105 collects the dust on the work surface in the dust box assembly 110 after cleaning the work surface. The cleaning module may also include a roller brush 105 disposed at the suction opening for sweeping the debris from the work surface and drawing the debris through the suction opening into the dust box assembly 110.

To achieve the basic functions of the cleaning robot 10, the cleaning robot 10 in the embodiments of the present disclosure may further include other necessary modules or components, such as an edge brush, a suction port, a battery, a motor, and the like. It should be noted that any suitable existing configuration may be selected for the other necessary modules or components included in the cleaning robot 10. For clarity and brevity, the technical solutions provided in the present disclosure will not be described in detail herein.

The cleaning robot 10 of the embodiment of the disclosure may be one of the sweeping and mopping integrated machines, and the sweeping robot can drive the cleaning module to contact with a working surface, for example, a ground surface, so as to clean the ground surface.

Referring to fig. 1 to 4 in combination, a cleaning robot system according to a first embodiment of the present disclosure includes a cleaning robot 10, the cleaning robot 10 includes a main body 101, a dust box assembly 110 and a first fan assembly 140 are disposed on the main body 101, the dust box assembly 110 includes a dust box main body 112 disposed in a hollow manner, a dust inlet 115 and an air outlet 117 respectively disposed on the dust box main body 112, and a filter connected to the dust box main body 112, the first fan assembly 140 is configured to generate a first air flow to drive garbage on a working surface to enter the dust box assembly 110 through the dust inlet 115, the filter includes a first filter 111 and a second filter 113 selectively combined or separated from each other, the second filter 113 is disposed at a position contacting the first air flow with respect to the first filter 111, the first filter 111 and the second filter 113 have a first state and a second state, in which the first filter 111 and the second filter 113 are combined with each other so that the second filter filters the garbage in the first air flow before the first filter, and in which the first filter 111 and the second filter 113 are moved closer to each other or at least one of the two filters are separated from each other by the first filter 111.

So set up, when first filter unit and second filter unit are in the first state, the rubbish that the first air current drove gets into dirt box main part 112 passes through second filter unit 113 earlier, and second filter unit 113 filters a part rubbish earlier, like cotton wool, hair, big granule rubbish etc. and then passes through first filter unit 111, and the less partial filtration of volume in the rubbish is filtered by second filter unit 113, keeps away cotton wool like this, avoids hair and big granule rubbish adhesion on first filter unit 111, is difficult to clear up. Meanwhile, when the first filtering part and the second filtering part are in the second state, the first filtering part 111 and the second filtering part 113 are at least partially separated from each other, so that the garbage between the two parts can be cleaned manually or automatically. Specifically, the second filtering part 113 is provided as a filter screen which is easy to intercept cotton, hair and large particle garbage in the first air flow and to clean up the garbage adhering thereto. The filter screen can be set to the metal filter screen, and the adhesion of the filter screen of metal texture to rubbish is less, is convenient for clear up rubbish on the filter screen. The first filter 111 is provided as HEPA.

In a further embodiment, the cleaning robot system further comprises a base station 30 for maintaining the cleaning robot 10, the base station 30 is configured to be docked with the cleaning robot 10 to recycle the garbage in the dust box assembly 110 into the base station 30, the first filtering part 111 and the second filtering part 113 are in a first state when the cleaning robot 10 performs cleaning operation, and the first filtering part 111 and the second filtering part 113 are in a second state during at least part of the process of recycling the garbage in the dust box assembly 110 by the base station 30.

The base station 30 is used for parking the cleaning robot 10, returning supplementary energy when the energy is insufficient, or carrying out central dust collection when the energy is stopped, and when the amount of the garbage in the dust box assembly 110 reaches a certain amount, the base station 30 carries out automatic central dust collection and recovery on the garbage in the dust box assembly 110, so that the step of manually cleaning the dust box assembly 110 by a user is omitted.

It should be noted that, the process of the base station 30 returning the garbage in the dust box assembly 110 includes the whole process of the base station 30 receiving the signal that the cleaning robot 10 needs to collect the dust, docking the cleaning robot 10 with the base station 30, starting the recycling assembly of the base station 30 one or more times after docking is successful (including the process between two starts of the recycling assembly), and recycling the garbage in the dust box assembly 110 to the base station 30.

As shown in fig. 6, 7 and 9, in the realizable mode of the disclosure, the second filtering portion 113 is attached to the first filtering portion 111 by an elastic force of an elastic structure (the first elastic member 1132) and combined with the first filtering portion 111.

In other possible implementations of the disclosure, the first filter part 111 and the second filter part 113 may be combined with each other in a plurality of ways, for example, when the cleaning robot 10 performs a cleaning operation, the first air flow generated by the first fan assembly 140 flows from the second filter part 113 to the first filter part 111, so that the first filter part 111 and the second filter part 113 are combined with each other, and in this arrangement, the first fan assembly 140 may be shared to combine the first filter part 111 and the second filter part 113 with each other without increasing manufacturing and usage costs, so that costs and space are saved. For example, a motor may be disposed corresponding to at least one of the first filtering portion 111 and the second filtering portion 113 to drive the two to be combined with each other, and the combination manner may be that one of the first filtering portion 111 and the second filtering portion 113 moves toward the other or that the two move toward each other, which is not described herein.

In one embodiment, the first filter unit and the second filter unit may be combined in such a manner that a distance between the second filter unit and the first filter unit is within a preset range. The preset range here can be freely set. For example, it may be selected from [0-3cm ]. Further, a support is arranged in the dust box main body, the first filtering part is connected with the dust box main body through the support, and the periphery of the second filtering part is at least partially attached to the periphery of the support, that is to say, the periphery of the second filtering part is tightly attached to the periphery of the support, so that dust is prevented from directly reaching the first filtering part without passing through the second filtering part.

It will be appreciated that the combination of the first filter portion 111 and the second filter portion 113 preferably has a form of completely fitting the first filter portion 111 and the second filter portion 113, and that the second filter portion 113 may be at least partially in contact with the surface of the first filter portion 111 or not in contact with the surface of the second filter portion 113, i.e. a certain gap is left between the first filter portion 111 and the second filter portion 113, so that the filter body can better filter the garbage and dust, and the ventilation of air between the first filter portion 111 and the second filter portion 113 is facilitated. Here, as long as it is ensured that the cleaning robot 10 performs a cleaning work, the second filter part 113 covers at least a part of the surface of the first filter part 111 so that the sucked garbage reaches the second filter part 113 before reaching the first filter part 111, it is possible to satisfy that the first filter part 111 and the second filter part 113 are combined with each other.

Preferably, when the cleaning robot 10 performs a cleaning operation, the second filter part 113 is disposed in parallel with the first filter part 111, and the second filter part 113 completely covers the first filter part 111.

It will be appreciated that at least a portion of the first filter part 111 and the second filter part 113 may be separated from each other to form a passage through which the waste is dropped, in which one of the first filter part 111 and the second filter part 113 is opened at an angle relative to the other to form a passage 1111 through which the waste attached to the first filter part 111 and the waste between the first filter part 111 and the second filter part 113 is dropped, for example, the second filter part 113 is rotated at an angle relative to the first filter part 111 in a direction away from the first filter part 111, so that the second filter part 113 is opened relative to the first filter part 111 to form the passage 1111, or a part of the structure of one of the first filter part 111 and the second filter part 113 is displaced to form a passage through which the waste is dropped, or the second filter part 113 is completely separated from the first filter part 111 to move in a translational manner, and the second filter part 113 is opened at an angle relative to the first filter part 111, which is not repeated. As long as the relative displacement between the second filtering parts 113 of the first filtering part 111 is generated to form the channel 1111 when the recycling assembly is used for recycling the garbage in the dust collecting box assembly 110, the garbage (dust) on the first filtering part 111 and the garbage (dust) between the first filtering part 111 and the second filtering part 113 can be ensured to fall from the channel 1111, so that the cleaning effect is improved.

It is also understood that at least portions of the first filter part 111 and the second filter part 113 are adjacent to each other to form a passage through which the garbage falls, and that the first filter part 111 and the second filter part 113 may have a certain distance therebetween when the cleaning robot performs a cleaning operation, and the second filter part 113 covers at least a portion of the surface of the first filter part 111, and in this embodiment, the second filter part 113 completely covers the first filter part 111. The first air flow passes through the second filtering part 113 to filter out large-particle garbage, hair, etc., and then passes through the first filtering part 111 to filter out fine dust. In order to form the above-described passage, when one of the second filter portion 113 and the first filter portion 111 is moved in a direction approaching the other, for example, the second filter portion 113 is rotated by a certain angle in a direction approaching the first filter portion 111, the second filter portion 113 is opened to form the above-described passage 1111 with respect to the first filter portion 111. Similarly, the second filtering portion 113 may be partially or entirely adjacent to the first filtering portion 111 to form the above-mentioned channel.

In the above-described cleaning robot system, when the cleaning robot 10 performs a cleaning operation, the cleaning robot 10 generates a first air flow to suck the dust on the floor through the first fan assembly 140, so that the dust enters the dust box body 112 through the dust inlet 115 of the dust box body 112. Meanwhile, the first air flow circulates from the second filtering part 113 to the first filtering part 111, the first air flow drives the garbage to flow through the filtering body, the garbage entering the dust box main body 112 driven by the first air flow passes through the second filtering part 113, the second filtering part 113 filters out part of the garbage, such as cotton wool, hair, large particle garbage and the like, and then passes through the first filtering part 111, and the part of the garbage with smaller volume is filtered out by the second filtering part 113, so that the cotton wool, the hair and the large particle garbage are prevented from adhering to the first filtering part 111 and are difficult to clean. Preferably, the second filtering part 113 is provided as a filter screen which is easy to intercept cotton, hair and large particle garbage in the first air flow and to clean up the garbage adhered thereto. The filter screen can be set to the metal filter screen, and the adhesion of the filter screen of metal texture to rubbish is less, is convenient for clear up rubbish on the filter screen. Further preferably, the first filter 111 is provided as HEPA.

Meanwhile, the first filtering part 111 and the second filtering part 113 combined with each other filter out the garbage and dust carried by the first air flow under the action of the filtering function thereof, and the first air flow flows out from the air outlet 117 of the dust box main body 112 after passing through the filtering body.

Thus, when the cleaning robot 10 performs a cleaning operation, the first filter part 111 and the second filter part 113 are combined with each other such that the second filter part 113 covers at least a portion of the surface of the first filter part 111, and the cleaning ability of the cleaning robot is improved by double filtering.

During at least a portion of the return of the base station 30 to the dust box assembly 110, the first filter portion 111 and the second filter portion 113 are at least partially separated from each other. Since the second filter part 113 covers the surface of the first filter part 111 when the cleaning robot 10 performs a cleaning operation, a part of dust remains therebetween, which is difficult to clean, and when the base station 30 recovers the dust in the dust box, the first filter part 111 and the second filter part 113 are separated from each other, so that the dust therebetween together with the dust in the dust box main body 112 can be recovered into the base station 30.

The cleaning robot system described above can automatically clean up the dust in the cleaning dust box assembly 110, including the dust remaining in the space between the first filter part 111 and the second filter part 113, so that the cleaning robot 10 can maintain a better suction force for a long time while reducing the user's intervention.

In one embodiment, the cleaning robot system includes a second blower assembly 301, the second blower assembly 301 being configured to generate a second air flow to move the second filter portion 113 relative to the first filter portion 111 such that at least a portion of the second filter portion is remote from the first filter portion, forming a channel. The second fan assembly may include a fan in communication with an air duct (e.g., dust collection channel 302) in communication with the dust box assembly (e.g., in communication with dust collection port 119 in the dust box body), the fan being activated to generate a second air flow within the dust box body, which in turn moves the second filter portion 113 relative to the first filter portion 111. Specifically, the second filtering portion may be driven to move in a direction away from the first filtering portion 111.

Specifically, since the cleaning robot system further includes a base station 30 for maintaining the cleaning robot, the base station 30 includes a recovery assembly configured to communicate with the dust box assembly in an air flow to suck the dust in the dust box assembly into the base station, and the recovery assembly includes a second fan assembly, the second air flow generated by the second fan assembly is further configured to return the dust in the dust box assembly. That is, the second fan assembly in the cleaning robot system is set as a recovery assembly of the base station (the structure of the recovery assembly refers to the structure of the second fan assembly and is not described in detail), the recovery assembly of the base station is directly utilized to generate the second air flow, the second air flow can drive the second filtering portion 113 to move relative to the first filtering portion 111, and the garbage in the dust box main body can be pumped into the base station (such as a dust box arranged in the base station), so that the additional fan assembly is not needed, and the cost and the volume of the cleaning robot system can be effectively reduced.

In another preferred embodiment of the present disclosure, the cleaning robot 10 is further provided with a first driving motor (not shown) connected to the second filtering part 113 to drive at least part of the second filtering part 113 away from the first filtering part 111. In a preferred embodiment of the present disclosure, the second filter portion 113 is angled with respect to the first filter portion 111 when the recycling assembly returns the dust in the dust box assembly 110.

Accordingly, in an alternative embodiment of the present disclosure, the second filter portion 113 is rotatably connected to the dust box body 112, so as to facilitate separately driving the second filter portion 113 and/or the first filter portion 111 to be combined with or separated from each other.

Specifically, taking the first driving motor as an example to drive the second filter part 113 to rotate, when the cleaning robot 10 performs cleaning operation, the first driving motor drives the second filter part 113 to rotate so that the second filter part 113 covers at least part of the surface of the first filter part 111, and when the cleaning robot 10 returns to the base station 30 to perform dust collection operation, the first driving motor drives the second filter part 113 to reversely rotate so as to drive at least part of the second filter part 113 to be far away from the first filter part 111.

Further, a bracket 114 is disposed in the dust box main body 112, the first filtering portion 111 is connected to the dust box main body 112 through the bracket 114, one end of the second filtering portion 113 is rotatably connected to the inner wall of the dust box main body 112, and the opposite end is a free end. Or one end of the second filtering part 113 is rotatably connected to the bracket 114 or the first filtering part 111, and the opposite end is a free end, and the second air flow drives the free end to move so that the free end is far away from the first filtering part.

In a preferred embodiment of the disclosure, the dust box body 112 includes a bottom wall 1122, a top wall 1121, and a side wall 1123 connecting the bottom wall 1122 and the top wall 1121, with the first filter portion 111 being proximate to either the side wall 1123 or the top wall 1121. Wherein the bottom wall is closer to the work surface than the top wall when the cleaning robot is at the work surface.

When the first filter part 111 is arranged on the top wall 1121 of the dust box main body 112, the first filter part 111 can be parallel to the top wall 1121 of the dust box main body 112 or can be angled with the top wall 1121 of the dust box main body 112, in the arrangement mode, when the cleaning robot 10 returns to the base station 30 to perform dust collection, the second filter part 113 can be at least partially far away from the first filter part 111 under the action of self gravity, and at the moment, the garbage attached on the first filter part 111 and the second filter part 113 also falls under the action of gravity.

When the first filter part 111 is arranged close to the side wall 1123 of the dust box main body 112, the first filter part 111 can be arranged parallel to the side wall 1123 of the dust box main body 112 or can be arranged at an angle with the side wall 1123 of the dust box main body 112, when the cleaning robot 10 returns to the base station 30 to perform dust collection, the second filter part 113 is partially opened away from the first filter part 111, garbage between the second filter part 113 and the first filter part 111 falls under the action of the second air flow and self gravity, and at the moment, the garbage falling from the second filter part 113 cannot fall onto the first filter part 111 again because the first filter part 111 is arranged close to the side wall 1123 of the dust box main body 112, so that better dust collection effect is realized.

In the present embodiment, a rotation shaft 116 is provided between the second filter unit 113 and the dust box main body 112, the second filter unit 113 is configured to rotate around the rotation shaft 116, one surface of the first filter unit 111 is adjacent to the side wall 1123, the other surface is adjacent to the first filter unit 111, the rotation shaft 116 is connected to the upper end of the second filter unit 113, and the free end is the lower end of the second filter unit. Thus, when the recycling assembly returns the garbage in the dust collection box assembly 110, the second air flow drives the lower end of the second filtering portion 113 to be far away from the lower end of the first filtering portion 111. At this time, the second filter portion 113 is angled with respect to the first filter portion 111. And when the cleaning robot 10 performs a cleaning work, the second filtering part 113 is disposed in parallel with the first filtering part 111. Specifically, the first filter part 111 is parallel to the height direction of the main body 101, and the second filter part 113 is also parallel to the first filter part 111 when the cleaning robot 10 performs a cleaning operation.

In an alternative embodiment, the shaft 116 may be perpendicular to the top wall 1121 of the main body 112 of the dust box, or may be parallel to the top wall 1121 of the main body 112 of the dust box, so long as the second filtering part 113 is ensured to be selectively combined with or separated from the first filtering part 111. In this embodiment, the rotation axis 116 is preferably disposed parallel to the top wall 1121 of the dust box body 112. So configured, the second filter portion 113 can leak down the dust between the first filter portion 111 and the second filter portion 113 by a small angle with respect to the first filter portion 111, and is carried away by the second air flow, and if the rotation axis 116 is perpendicular to the top wall 1121 of the dust box main body 112, the second filter portion 113 can leak down the dust between the first filter portion 111 and the second filter portion 113 near the rotation axis 116 by a large angle with respect to the first filter portion 111.

When the cleaning robot system of the present disclosure is operated, the second filter part 113 rotates about the rotation shaft 116 as the rotation shaft 116 through the rotation shaft 116 provided between the second filter part 113 and the dust box main body 112, and is combined or angularly separated with respect to the first filter part 111.

When the cleaning robot 10 performs a cleaning operation, the second filter part 113 is disposed in parallel with the first filter part 111, and the first air flow generated by the first fan assembly 140 flows from the second filter part 113 toward the first filter part 111, so that the first filter part 111 and the second filter part 113 are combined with each other. At this time, the air flow drives the cleaned garbage to flow through the first filtering part 111 and the second filtering part 113 for double-layer filtering. When the cleaning robot 10 returns to the base station 30 to perform dust collection, the second air flows from the first filter part 111 to the second filter part 113, the second filter part 113 rotates around the rotation shaft 116 to be angularly separated from the first filter part 111, and the separation can be mutually separated by driving the motor or the second filter part 113 can be angularly separated from the first filter part 111 by the second air, and the dust adhering to the first filter part 111 and the second filter part 113 and the dust remaining between the first filter part 111 and the second filter part 113 enter the recovery assembly along with the second air, thereby completing dust collection.

In a further embodiment, referring to fig. 5-9, an ash removing device is disposed inside the cleaning robot 10, and at least a part of the ash removing device is configured to act on the first filtering portion 111 to remove dust attached to the first filtering portion 111. In order to further reduce maintenance of the dust box assembly 110 by a user, an ash removing device is arranged inside the cleaning robot 10 to automatically clean dust on the first filter part 111, so that the user is prevented from frequently detaching the first filter part 111 from the dust box main body 112 and cleaning the dust box main body manually.

Still further, the ash removal device is configured to be activated after the base station returns the trash in the dust box assembly at least once. So set up, ash removal device retrieves the rubbish in the subassembly most before the start-up and has retrieved in the basic station, can not influence the range of ash removal device's operation.

Specifically, referring to fig. 34 to 41, a bracket 114 is provided in the dust box body 112, and the first filter 111 is connected to the dust box body 112 through the bracket 114. In one embodiment, the ash removal device includes a first drive module coupled to the dust box body 112, the first drive module configured to act on the support 114 to move the support 114 and the first filter 111 between a first position in which the first filter 111 rests near a center of the dust box body 112 and a second position in which the first filter 111 rests away from the center of the dust box body 112 relative to the first position, and in which dust adhering to the first filter 111 falls into the dust box body 112 at least under inertia when the first filter 111 moves from the second position and stops in the first position. Through the first filtering part 111 from moving to the first position at the second position and stopping at the first position instantaneously, the dust on the first filtering part 111 falls into the dust box main body 112 through inertia, the dust box assembly 110 is not required to be cleaned manually, frequent disassembly and assembly of the dust box assembly 110 are avoided, and the cleaning capability of the cleaning robot 10 is not affected. In other embodiments, the ash removal device may have other structures, which will be described in detail below.

In the present embodiment, the first filter 111 is mounted to the bracket 114 and moves in synchronization with the bracket 114. In other embodiments, the dust box assembly 110 may not be provided with the bracket 114, and the first filtering portion 111 is directly mounted on the inner wall of the dust box main body 112 and is driven by the first driving module to move between the first position and the second position.

It should be noted that, the first filter 111 moves from the second position and stops at the first position once to perform one beating of the first filter 111, and the bracket 114 and the first filter 111 move between the first position and the second position multiple times, and the first filter 111 moves from the second position and stops at the first position multiple times to perform beating of the first filter 111 multiple times, so that the ash cleaning effect is better.

As shown in connection with fig. 6-8, in an alternative embodiment of the disclosure, the dust box body 112 includes a bottom wall 1122, a top wall 1121, and a side wall 1123 connecting the bottom wall 1122 and the top wall 1121, with the first filter portion 111 disposed proximate the top wall 1121. When the first filter portion 111 is proximate the top wall 1121 and in the first position, the first filter portion 111 is angled with respect to the top wall 1121. This arrangement facilitates the dust adhering to the first filter part 111 to fall into the dust box main body 112 by gravity. Further, the first position is closer to the work surface than the second position, i.e. the second position is higher than the first position, in the direction of gravity. At this time, the first filter portion 111 is disposed proximate to the top wall 1121.

In other implementations of the disclosure, when the first filtering portion 111 is proximate to the top wall 1121 and is in the first position, the first filtering portion 111 and the top wall 1121 may be disposed in parallel, and this arrangement is also convenient for the garbage attached to the first filtering portion 111 to fall into the dust box main body 112 under the action of gravity. Referring to fig. 9, in the present embodiment, the top wall 1121 is configured as a flip cover capable of being flipped with respect to the dust box body, so that a user can open or close the dust box body to perform maintenance on the dust box body. Of course, in other embodiments of the present disclosure, the first filtering portion 111 may be disposed close to other walls of the main body 112 of the dust box, which will be described in detail below, and not described herein.

In an implementation of the disclosure, the support 114 may be connected to the dust box body 112 and may be movable relative to the dust box body 112, or the support 114 may be movable relative to the dust box body 112 by providing a motor to drive the support 114. In a preferred embodiment of the disclosure, as shown in fig. 6-8 and fig. 22-23, a rotating shaft 116 is disposed between the dust box main body 112 and the support 114, and the support 114 rotates with the rotating shaft 116 as a rotation center, so as to drive the first filtering portion 111 to move between the first position and the second position. Of course, in other implementations, the bracket 114 can also move the first filtering portion 111 between the first position and the second position in a manner that produces an overall displacement in a certain direction, which is not limited in this disclosure.

In the implementation manner of the disclosure, the rotating shaft 116 may be disposed at different positions of the support 114, preferably, when the first filtering portion 111 is disposed proximate to the top wall 1121, the rotating shaft 116 is parallel to the top wall 1121, and the rotating shaft 116 may be disposed on the top wall 1121 or on the side wall 1123 of the dust box main body 112.

In the implementation manner of the present disclosure, the first filtering portion 111 and the bracket 114 may be fixedly connected, or may be detachable from each other, or may be movably combined with/separated from each other, and preferably, the first filtering portion 111 and the bracket 114 are connected and separated by a mutually matched fastening structure. This arrangement allows the first filter unit 111 to be easily attached to and detached from the bracket 114.

Referring to fig. 5 in combination, in this embodiment, a recycling assembly is provided on the base station 30 and is configured to be in airflow communication with the dust box assembly 110 to draw the dust in the dust box assembly 110 into the base station 30.

Further, after the recycling assembly recycles the garbage in the dust box assembly 110 at least once, the first driving module drives the bracket 114 and the first filtering part 111 to move between the second position and the first position at least once. By this arrangement, the base station 30 can empty the dust box assembly 110 of the dust box, prevent the dust box from excessively obstructing the falling of the first filtering part 111, and simultaneously enable the second filtering part 113 to move in the dust box assembly 110 in a sufficient space. In other embodiments, the base station 30 may return the dust of the dust box assembly 110 by dumping, for example, the base station 30 may be provided with a robotic arm that removes the dust box assembly 110 from the cleaning robot 10 and dumps the dust in the dust box assembly 110 into a dust bin 303 provided in the base station 30.

Referring to fig. 5 in combination, when dust on the filter body needs to be cleaned, the recovery assembly inside the base station 30 is in air flow communication with the dust box body 112 to suck the dust in the dust box body 112 to the recovery assembly inside the base station 30. The filter body of the cleaning robot 10 is prevented from being clogged, thereby ensuring the cleaning efficiency of the cleaning robot 10.

Accordingly, in an implementation of the present disclosure, the recycling assembly includes a second blower assembly 301, the second blower assembly 301 being configured to generate a second airflow to recycle the waste within the dust box assembly 110. The base station 30 further comprises a control unit, wherein the control unit controls the second fan assembly 301 to be started for a preset time and/or for a preset number of times, and when the second fan assembly 301 is started, garbage in the dust collection box assembly 110 is returned. In other realizable modes of the disclosure, the garbage in the recycling assembly recycling dust box assembly 110, the first driving module driving bracket 114 and the first filtering part 111 can move between the second position and the first position at least once, and can be synchronously or sequentially carried out, and the operation times of the two can be specifically set according to the needs, and are not repeated here. The recycling assembly further includes a dust collection channel 302 in airflow communication with the dust box assembly, and a dust bin 303 connected to the dust collection channel 302 for collecting dust, the dust bin 303 being disposed at the base station.

In addition, referring to fig. 1 and 5, the second air flow is configured to blow from a side of the second filter portion adjacent to the first filter portion to a side of the second filter portion remote from the first filter portion, so as to blow the garbage from the side of the second filter portion remote from the first filter portion. The second air flow can also clean the garbage attached to the second filtering part, so that the second filtering part is cleaned.

In an implementation manner of the disclosure, during at least a part of the process of starting the ash cleaning device, the matching relationship between the first filtering portion 111 and the second filtering portion 113 is in the second state. That is, during at least part of the activation of the ash removal device, the first filter portion 111 and the second filter portion 113 are at least partially separated from each other. When the ash cleaning device starts to clean the dust on the first filtering part 111, the dust attached to the first filtering part 111 falls into the space between the first filtering part 111 and the second filtering part 113, and is difficult to clean. If the second filter unit 113 is separated from the first filter unit 111 during cleaning of the first filter unit 111, dust of the first filter unit 111 can fall into the dust box main body 112 and be recovered into the base station 30 by the second fan assembly 301.

It should be noted that, the process of starting the ash removal device includes that after the cleaning robot 10 receives a signal that the first filtering portion 111 needs to be cleaned, the first driving module drives the support 114 to start moving, and the support 114 moves between the first position and the second position one or more times until reaching the preset number of times inside the cleaning robot 10, and then the first driving module drives the support 114 to return to the position (the first position or the second position) where the support 114 is located when the cleaning robot 10 performs the cleaning operation.

Further, the second filtering portion 113 is connected to the bracket 114 or the first filtering portion 111, and can move relative to the bracket 114, so that the second filtering portion 113 and the first filtering portion 111 can be selectively combined or separated from each other. When the second filter unit 113 is connected to the first filter unit 111, it can be detached from the bracket 114 together with the first filter unit 111. Maintenance of the second filter portion 113 is facilitated.

Specifically, the second filter portion 113 is connected to the bracket 114 or the first filter portion 111 and is movable 114 with respect to the bracket, and the second filter portion 113 and the first filter portion 111 are separated from each other when the first filter portion 111 moves from the second position and stops at the first position.

Referring to fig. 6 to fig. 9 in combination, in the realizable mode of the disclosure, a first elastic member 1132 is further connected between the bracket 114 and the second filtering portion 113, and the second filtering portion 113 is attached to the first filtering portion 111 under the elastic force of the first elastic member 1132. By the elastic deformation of the first elastic member 1132, a force is provided for the second filtering part 113 to move close to the first filtering part 111, and the second filtering part 113 can be separated from the first filtering part 111 when receiving other external force. The first elastic member 1132 may be a torsion spring, an elastic rope, a spring, etc., and in the preferred embodiment of the present disclosure, the first elastic member 1132 is a torsion spring.

In the embodiment of the disclosure, the second filtering part 113 is connected to the bracket 114, and the bracket 114 and the second filtering part 113 are hinged by a first hinge 1131. The first hinge portion 1131 enables the second filter portion 113 to rotate at an angle with respect to the bracket 114 and the first filter portion 111, thereby separating the second filter portion 113 from the first filter portion 111. In other embodiments, the second filter portion 113 may be connected to the first filter portion 111, and the first filter portion 111 and the second filter portion 113 may be hinged to each other by the first hinge portion 1131. Of course, in other implementations, the second filter portion 113 may not be hinged to the bracket 114 or the first filter portion 111, but may be integrally displaced in a certain direction relative to the bracket 114 or the first filter portion 111 by other structures, so as to combine or separate the first filter portion 111 and the second filter portion 113. For example, a sliding groove is provided on the second filtering part 113, a sliding block is provided on the bracket 114, and the sliding block moves along the sliding groove under the action of external force, and the second filtering part 113 moves along the sliding groove to be far from or near to the first filtering part 111.

In the preferred embodiment of the disclosure, an abutment stand 1124 is disposed at a side of the dust box main body 112, and when the driving module drives the bracket 114 and the first filter part 111 to move from the second position and stop at the first position, the abutment stand 1124 prevents the bracket 114 and the first filter part 111 from moving in a direction away from the second position beyond the first position, and the second filter part 113 moves in a direction away from the second position from the first position against the elastic force of the first elastic member 1132 under the inertial action, so that the second filter part 113 and the first filter part 111 are separated from each other.

Preferably, the first hinge portion 1131 is disposed at one end of the second filtering portion, and a weight body for increasing the weight of the second filtering portion 113 is disposed at one end of the second filtering portion 113 away from the first hinge portion 1131. By adding a weight to make the inertia of the second filter portion 113 to continue to move in the opposite direction of the second position larger, the second filter portion 113 and the first filter portion 111 can be better separated from each other. Accordingly, the weight of the weight body may be set according to the torsion of the first elastic member 1132, which will be described further below.

Preferably, when the second filtering part 113 is separated from the first filtering part 111, the second filtering part 113 forms an included angle with the first filtering part 111, and the included angle is preferably greater than or equal to 15 °. So set up, on the one hand control second filter part 113 opens the angle and is greater than or equal to 15, can effectively avoid adhering to the dust on the first filter part 111 and fall into the dust box subassembly 110 and receive the hindrance when, on the other hand when starting second fan subassembly back to gather dust box interior rubbish, the two sides adhesion rubbish of second filter part 113 can both be cleared up by the air current that the second fan subassembly produced. It will be appreciated that when the second filter unit 113 is combined with the first filter unit 111, part of the recovered air flow generated by the second fan assembly enters the dust box assembly 110 from the first filter unit 111, and then the side, close to the first filter unit 111, of the second filter unit 113 is blown to the side, far away from the first filter unit 111, of the second filter unit 113, and the garbage on the side, far away from the first filter unit 111, of the second filter unit 113 is blown down, and when the driving module drives the bracket 114 and the first filter unit 111 to move from the second position and stop at the first position, the second filter unit 113 is separated from the first filter unit 111, and part of the garbage on the side, close to the first filter unit 111, of the second filter unit 113 is subjected to inertial drop. Meanwhile, when the recycling assembly returns the garbage in the dust collection box assembly 110, part of the airflow generated by the second fan assembly enters the dust collection box assembly 110 through the dust inlet 115, the surface, far away from the first filter part 111, of the second filter part 113 is blown to the surface, close to the first filter part 111, of the second filter part 113, and the garbage, close to the surface of the first filter part 111, of the second filter part 113 is blown down, so that the garbage attached to the surface, close to the first filter part 111, of the second filter part 113 and the surface, far away from the first filter part 111, is cleaned.

In the implementation manner of the disclosure, the first elastic member 1132 is a torsion spring, the length of the second filtering part 113 is 40mm, the second filtering part 113 is connected to one end of the bracket 114 in the length direction, the torsion spring force is 0.5N, the total mass of the counterweight body and the second filtering part 113 is configured to be 15g, the opening angle of the second filtering part 113 relative to the bracket 114 is 15 degrees, and correspondingly, under the condition that other conditions are unchanged, when the mass of the counterweight body and the second filtering part 113 is larger than 15g, the opening angle of the second filtering part 113 is larger than 15 degrees, for example, when the mass of the counterweight body and the second filtering part 113 is 20g, the opening angle of the second filtering part 113 relative to the bracket 114 is 25 degrees. The length of the second filtering portion 113, the weight of the counterweight body, and the torsion spring force of the torsion spring may be selected according to the requirement of use, and will not be further described herein.

In an implementation of the disclosure, referring to fig. 6-13, in the dust box assembly 110 provided in the embodiment of the disclosure, a sealing member 120 is disposed between the bracket 114 and the dust box body 112, and when at least the first filtering portion 111 is in the first position, the sealing member 120 prevents dust in the dust box body 112 from leaking from between the dust box body 112 and the bracket 114.

As shown in connection with fig. 6-9, the seal 120 may be a rubber strip mounted on the bracket 114. When the bracket 114 and the first filtering part 111 are in the first position, the rubber strip is abutted against the inner wall of the dust box assembly 110, so that a sealing effect is achieved. In this embodiment the seal 120 only seals the gap between the holder 114 and the dust box body 112 in the first position, and the rubber strip does not interfere with the inner wall of the dust box assembly 110 when the holder 114 and the first filter part 111 are moved away from the first position, thus losing the sealing effect. Therefore, when the sealing member 120 is provided as the rubber strip, it is not suitable for the embodiment in which the first filter part 111 in the dust box assembly 110 in the cleaning robot 10 is in the second position when the cleaning robot 10 performs the cleaning work. Referring to fig. 12-13 in combination, the seal 120 may also be a flexible member 121 of variable configuration attached to the support 114 and the inner wall of the dust box body 112, and the flexible member 121 may provide a sealing effect throughout the movement of the support 114. Therefore, the sealing member 120 is adapted to the cleaning robot system provided in any one of the embodiments of the present disclosure when provided as the flexible member 121. A sealing structure 122 is also provided between the first filter unit 111 and the bracket 114 to prevent dust from escaping from the gap between the first filter unit 111 and the bracket 114.

Correspondingly, the driving module is further connected with an extension piece 130, the driving module is configured to drive the extension piece 130 to move between an extension position and a retraction position, the extension piece 130 is in the extension position, when the second elastic piece 1141 drives the bracket 114 and the first filtering portion 111 to move from the second position to the first position, the extension piece 130 directly abuts against the bracket 114 and prevents the bracket 114 and the first filtering portion 111 from continuing to move to the first position, and when the extension piece 130 retracts, the second elastic piece 1141 continues to drive the bracket 114 and the first filtering portion 111 to move to the first position. Specifically, the extension member 130 can be extended and retracted, and the second elastic member 1141 drives the bracket 114 and the first filtering portion 111 to move from the second position to the first position, if the extension member 130 is in the extended position, the bracket 114 directly impacts on the extension member 130 to stop moving instantaneously, so as to play a role in beating the first filtering portion 111, and at this time, the first filtering portion 111 is located in a third position between the first position and the second position. The sealing member 120 is not in contact with the protrusion 130, and the beating effect of the sealing member 120 is not affected by the buffering effect. After the tapping is finished once, the extension piece 130 is retracted, the bracket 114 continuously moves downwards to the first position under the action of the second elastic piece 1141, when the bracket 114 and the first filter part 111 are stopped at the first position instantaneously, a tapping effect is achieved on the first filter part 111, the sealing piece 120 arranged on the bracket 114 is impacted on the abutting table 1124, a gap between the bracket 114 and the dust box main body 112 is sealed, the sealing piece 120 also provides a buffering effect while the sealing effect is achieved, and the tapping effect of the bracket 114 on the first filter part 111 by directly impacting on the extension piece 130 is stronger than the tapping effect of the sealing piece 120 on the abutting table 1124 on the first filter part 111. The above-described process realizes the double-beating of the first filtering part 111, and the beating effect is better.

In the preferred embodiment of the present disclosure, the protrusion 130 moves in synchronization with the first cam 1181 (or the second cam). Further, the driving motor 1182 drives the first cam 1181 to rotate while simultaneously driving the extension and retraction of the extension 130. Specifically, when the first cam 1181 drives the bracket 114 and the second filtering part 113 to move from the first position to the second position, the extension piece 130 is in the retracted position to avoid the extension piece 130 from preventing the bracket 114 and the first filtering part 111 from moving, when the first cam 1181 releases the bracket 114 and the first filtering part 111 to move from the second position back to the first position, the extension piece 130 is in the extended position to intercept the bracket 114 from continuing to move to the second position and stopping at the third position instantaneously.

Referring to fig. 1-4 and 6-8, an embodiment of the disclosure provides a dust box assembly 110, which includes a dust box main body 112 disposed in a hollow manner, a dust inlet 115 and an air outlet 117 respectively provided on the dust box main body 112, and a filter body connected to the dust box main body 112, wherein the filter body includes a first filter portion 111 and a second filter portion 113 for filtering the dust entering the dust box main body 112, and the dust box assembly 110 has two states in use, wherein the first filter portion 111 and the second filter portion 113 are combined with each other so that the second filter portion 113 filters the dust entering the dust box main body 112 before the first filter portion 111, and the second filter portion 111 and at least part of the second filter portion 113 are separated from each other to form a channel 1111 through which the dust falls.

Further, when the cleaning robot 10 performs a cleaning operation, the dust box assembly 110 is in a first state, the first filtering part 111 and the second filtering part 113 are combined with each other, and the second filtering part 113 covers at least a portion of the surface of the first filtering part 111, and the dust entering the dust box body 112 is filtered through the first filtering part 111 and the second filtering part 113 and stored in a hollow area inside the dust box body 112.

When the cleaning robot 10 enters the base station 30 to perform dust collection, the dust box assembly 110 is in the second state, and the first filtering part 111 and the second filtering part 113 are at least partially separated from or close to each other to form a passage 1111 through which the dust falls. So that the base station 30 can collect the garbage collected in the empty area of the dust box body 112 and the garbage attached between the first filtering part 111 and the first filtering part and the second filtering part 113.

It will be appreciated that the first filter part 111 and the second filter part 113 may be separated from each other to form a falling passage, in which one of the first filter part 111 and the second filter part 113 is opened at an angle relative to the other to form a falling passage 1111 through which the garbage attached to the first filter part 111 and the garbage between the first filter part 111 and the second filter part 113 can fall, for example, the second filter part 113 is rotated at an angle relative to the first filter part 111 in a direction away from the first filter part 111, the second filter part 113 forms the above-mentioned passage 1111 relative to the opened position of the first filter part 111, or part of the structure of one of the first filter part 111 and the second filter part 113 is displaced to form a falling passage for the garbage, or the two parts are completely separated, i.e. the second filter part 113 is moved in translation relative to the first filter part 111, and the second filter part 113 is opened at an angle relative to the first filter part 111, which is different from the first filter part 111, and the second filter part 113 is not repeated here. As long as the relative displacement between the second filtering parts 113 of the first filtering part 111 is generated to form the channel 1111 when the recycling assembly is used for recycling the garbage in the dust collecting box assembly 110, the garbage (dust) on the first filtering part 111 and the garbage (dust) between the first filtering part 111 and the second filtering part 113 can be ensured to fall from the channel 1111, so that the cleaning effect is improved.

It is also understood that the first filter part 111 and the second filter part 113 are close to each other to form a passage through which the garbage falls may be expressed in such a manner that a certain distance may be provided between the first filter part 111 and the second filter part 113 when the cleaning robot performs a cleaning operation, the second filter part 113 covers at least a part of the surface of the first filter part 111, and in this embodiment, the second filter part 113 completely covers the first filter part 111. The first air flow passes through the second filtering part 113 to filter out large-particle garbage, hair, etc., and then passes through the first filtering part 111 to filter out fine dust. In order to form the above-described passage, when one of the second filter portion 113 and the first filter portion 111 is moved in a direction approaching the other, for example, the second filter portion 113 is rotated by a certain angle in a direction approaching the first filter portion 111, the second filter portion 113 is opened to form the above-described passage 1111 with respect to the first filter portion 111. Similarly, the second filtering portion 113 may be partially or entirely adjacent to the first filtering portion 111 to form the above-mentioned channel. The above manner of cleaning the HEPA disposed on the dust box main body 112 is that the inside of the dust box assembly 110 knocks the back of the HEPA by using an eccentric vibration mode, so that the garbage falls from the HEPA, and the eccentric vibration mode has low vibration amplitude and frequency, which results in poor maintenance effect, and the knocking frequency is low, and meanwhile, the HEPA knocks on the back of the HEPA, so that the garbage on the HEPA is not easy to fall, and when the carpet and cotton wool/hair are cleaned more, the cleaning effect is not ideal.

Referring to fig. 28 to 31, in the second embodiment of the present disclosure, when the recycling assembly returns the garbage in the dust box assembly 110, the first filtering portion 111 and the second filtering portion 113 are at least partially separated from each other.

The base station 30 is provided with a recycling assembly configured for airflow communication with the dust box assembly 110 to draw the dust in the dust box assembly 110 into the base station 30. The recycling assembly includes a second fan assembly 301, the second fan assembly 301 being configured to generate a second airflow to recycle the waste within the dust box assembly 110. The second air flow is further configured to move the second filter portion 113 relative to the first filter portion 111 such that at least a portion of the second filter portion 113 is remote from the first filter portion 111 to form a channel 1111.

Specifically, the recycling component is disposed at the base station 30, the second fan component 301 generates a second air flow, the second air flow passes through the dust box component 110 and drives the second filtering portion 113 to move relative to the first filtering portion 111, so that the second filtering portion 113 is at least partially away from the first filtering portion 111, and therefore, dust adhering to the second filtering portion 113 can be sucked out by the second air flow from an opening (i.e. a channel 1111) between the second filtering portion 113 and the first filtering portion 111, and then, the dust and the dust are sucked into the recycling component of the base station 30 from the dust collecting port 119 of the dust box main body 112.

In this embodiment, when the cleaning robot 10 performs a cleaning operation, the first air flow generated by the first fan assembly 140 flows from the second filter unit 113 to the first filter unit 111, so that the first filter unit 111 and the second filter unit 113 are combined with each other, and the second filter unit 113 covers at least a part of the surface of the first filter unit 111.

It will also be appreciated that the first filter portion 111 and the second filter portion 113 are preferably in a form of being completely attached to each other, and that the second filter portion 113 may be at least partially in contact with the surface of the first filter portion 111 or not in contact with the surface of the second filter portion 113, i.e. a certain gap is left between the first filter portion 111 and the second filter portion 113, so that the filter body can better filter the garbage and dust, and also facilitate the ventilation of air between the first filter portion 111 and the second filter portion 113.
