[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0044] It should be noted that all directional indications, such as up, down, left, right, front, back, etc., in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0045] It should also be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or can have a middle element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or can be indirectly connected to the other element through a middle element.

[0046] In addition, the description of "first", "second", etc. in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of a person skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection claimed by the present application.

[0047] The cleaning robot can move in the pool to clean the garbage in the pool. When the cleaning robot is immersed in water for cleaning, the cleaning robot can move on the pool wall to clean the pool wall, for example, the pool bottom wall and the pool side wall. It should be noted that the pool side wall has a certain inclination angle compared with the bottom wall, for example, the pool side wall is vertical, and when the cleaning robot cleans the pool side wall, the cleaning robot needs to climb on the pool side wall to ensure effective cleaning of the pool side wall. In order to ensure that the cleaning robot can stably climb and clean on the pool side wall, the cleaning robot needs to be applied with a pressure towards the pool side wall, which can come from the reaction force of the cleaning robot sucking and spraying water flow. However, once the cleaning robot is partially exposed above the water surface, it may not be able to suck water flow, resulting in the failure of the pressure applied to the cleaning robot towards the pool side wall, and the cleaning robot will slide down from the pool side wall, resulting in cleaning failure.

[0048] Therefore, the embodiments of the present application provide a storage device and a cleaning robot, which can ensure that the cleaning robot can be attached to the pool side wall and is not easy to slide down, and can realize stable cleaning of the pool wall and is not easy to cause cleaning failure.

[0049] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0050] As shown in the drawings, Figures 1 to 4 A storage device 20 provided by the embodiments of the present application is applied to a cleaning robot 100, the storage device 20 is internally provided with a storage cavity, the bottom of the storage device 20 is provided with a suction port 21b and a negative pressure port 21c, the top of the storage device 20 is provided with a filter port 22b, the suction port 21b, the filter port 22b and the negative pressure port 21c are all communicated with the storage cavity, the filter port 22b is provided with a first filter screen 221, the negative pressure port 21c is provided with a swingable negative pressure baffle 211 on one side outside the storage cavity, the negative pressure baffle 211 can swing to cover the negative pressure port 21c or open the negative pressure port 21c, the negative pressure port 21c is located on the rear side of the suction port 21b along the direction of travel of the cleaning robot 100, and the negative pressure port 21c opens towards the opposite direction of the direction of travel of the cleaning robot 100; the bottom of the storage device 20 is used to face the pool wall, the filter port 22b is used to communicate with a suction device 80 of the cleaning robot 100, and the suction device 80 of the cleaning robot 100 sucks water flow through the filter port 22b to provide a pressure of the cleaning robot 100 towards the pool wall.

[0051] It should be noted that the cleaning robot 100 can clean the pool wall by the receiving device 20 when cleaning the pool wall, for example, by sucking the water flow through the suction port 21b to collect the garbage carried in the water flow. Alternatively, other structures can also be used to clean the pool wall, which is not limited.

[0052] It should be noted that the jet direction of the water flow sucked by the suction device 80 is away from the bottom of the cleaning robot 100, so as to be able to apply the pressure of the cleaning robot 100 to the pool wall. The jet direction can be perpendicular to the bottom of the cleaning robot 100, or can have an included angle, which is not limited.

[0053] It should be noted that when the cleaning robot 100 moves to clean the pool wall and the suction port 21b is exposed above the water surface, the cleaning robot 100 without the negative pressure port 21c and the negative pressure baffle 211 can no longer suck the water flow, the suction device 80 cannot suck the water flow, and the cleaning robot 100 can no longer be provided with the pressure of the water flow to the pool wall, so that the cleaning robot 100 will slide down and cause cleaning failure.

[0054] It should be noted that when the suction port 21b is below the water surface, the suction port 21b can stably suck the water flow, at this time, the difference between the external water pressure of the negative pressure baffle 211 and the pressure in the receiving cavity is greater than the gravity of the negative pressure baffle 211 itself, so that the negative pressure baffle 211 can be stably capped on the negative pressure port 21c. When the gravity of the negative pressure baffle 211 is greater than the difference between the external water pressure of the negative pressure baffle 211 and the pressure in the receiving cavity, the negative pressure baffle 211 can swing downward, so that the negative pressure port 21c is in an open state, the water flow can enter the receiving cavity along the negative pressure port 21c, and be sucked out by the suction device 80.

[0055] The storage device 20 of the embodiment of the present application is applied to the cleaning robot 100. When the cleaning robot 100 cleans the pool wall, the suction device 80 sucks, a negative pressure is formed in the storage cavity, the negative pressure baffle 211 swings to the cover negative pressure port 21c under the action of the negative pressure, the water flow can flow into the suction port 21b and flow out through the filter port 22b, the garbage is retained in the storage cavity under the blockage of the first filter screen, the water flow flowing out of the filter port 22b can be sucked out by the suction device 80, and the water flow sucked out by the suction device 80 can provide the cleaning robot 100 with a pressure towards the pool wall, so as to ensure that the cleaning robot 100 can be attached to the pool wall and stably clean the pool wall. When the cleaning robot 100 moves to clean the pool wall, part of the cleaning robot 100 is exposed above the water surface. When the suction port 21b is exposed above the water surface, the suction port 21b cannot suck the water flow any more, the suction port 21b is in communication with the outside air, and the pressure in the storage cavity increases. In the present application, the negative pressure port 21c is located at the rear side of the suction port 21b and is still located below the water surface. Due to the increase of the pressure in the storage cavity, the negative pressure baffle 211 swings to open the negative pressure port 21c under the action of the gravity. When the suction device 80 sucks the water flow, the water flow can flow into the negative pressure port 21c and flow out through the filter port 22b. The suction device 80 can still provide the cleaning robot 100 with the pressure towards the pool wall through the sucked water flow, so as to ensure that the cleaning robot 100 can continue to be attached to the pool wall and stably clean the pool wall. Therefore, the storage device 20 of the present application can ensure that the cleaning robot 100 stably cleans the pool wall and is not prone to cleaning failure.

[0056] In addition, the negative pressure port 21c and the negative pressure baffle 211 can allow the cleaning robot 100 to expose more areas when cleaning the pool wall, so that the effective cleaning area of the cleaning robot 100 when cleaning the pool can be greatly increased, so that the pool can be fully cleaned.

[0057] As shown in Figure 1 In the embodiment of the present application, the negative pressure baffle 211 can be a flexible sheet, one end of which is fixedly connected to one side edge of the negative pressure port 21c, and the other end is a free end. The negative pressure baffle 211 can swing relative to the negative pressure port 21c by deforming to open or cover the negative pressure port 21c. In other embodiments, the negative pressure baffle 211 can also be a rigid sheet, one end of which is rotatably connected to one side edge of the negative pressure port 21c, and the other end is a free end. The negative pressure baffle 211 can swing relative to the negative pressure port 21c by rotating to open or cover the negative pressure port 21c.

[0058] As shown in Figures 1 to 4As shown, in the embodiment of the present application, the negative pressure port 21c is provided with a second filter screen 212. It can be understood that the second filter screen 212 can allow water flow to pass through and block garbage from entering and exiting. When the suction port 21b is located underwater and sucks water flow, the water flow and the garbage carried in the water flow can be sucked into the collection cavity, and the garbage is retained in the collection cavity. After the negative pressure baffle 211 opens the negative pressure port 21c, the garbage can be blocked from flowing out of the negative pressure port 21c through the second filter screen 212, thereby ensuring reliable garbage collection of the cleaning robot 100. For example, in the case that the garbage in the collection cavity flows to the position of the negative pressure port 21c when cleaning the side wall of the pool, when the suction port 21b is exposed above the water surface, the negative pressure baffle 211 opens the negative pressure port 21c. Since the negative pressure port 21c is located at the rear side of the cleaning robot 100 in the direction of travel, the negative pressure port 21c is downward, and the garbage can be blocked from flowing out through the second filter screen 212. If the second filter screen 212 is not provided, the garbage in the collection cavity can flow out. Of course, in other embodiments, the second filter screen 212 can be provided in the collection cavity to divide the collection cavity into two areas, one side being the area communicated with the suction port 21b, and the other side being the area communicated with the negative pressure port 21c. On the one hand, the garbage sucked by the suction port 21b in the collection cavity cannot flow out from the negative pressure port 21c, and on the other hand, when the water flow is sucked through the negative pressure port 21c, the garbage in the water flow can also be accommodated in the area communicated with the negative pressure port 21c on the other side of the second filter screen 212. In this way, even if the suction port 21b is exposed above the water surface, the cleaning robot 100 can also achieve a certain degree of garbage collection.

[0059] As shown, Figures 1 to 4 In the embodiment of the present application, the filter port 22b is at least partially located at the rear side of the suction port 21b in the direction of travel of the cleaning robot 100. When the cleaning robot 100 moves to clean the side wall of the pool and the suction port 21b is exposed above the water surface, since the filter port 22b is at least partially located at the rear side of the suction port 21b, the filter port 22b is at least partially submerged underwater, and the filter port 22b and the negative pressure port 21c are both located underwater. When the suction device 80 sucks, it can stably suck the water flow, thereby ensuring that the cleaning robot 100 can apply a stable pressure to the side wall of the pool. It can be understood that the filter port 22b can also have a part of the position consistent with the suction port 21b in the direction of travel of the cleaning robot 100, and / or the filter port 22b can also have a part located at the front side of the suction port 21b in the direction of travel of the cleaning robot 100.

[0060] As shown, Figure 1As shown, in the embodiment of the present application, the bottom of the receiving device 20 is provided with a collection baffle 213, which is located at the rear side of the suction port 21b along the direction of travel of the cleaning robot 100. When the cleaning robot 100 travels for cleaning, the collection baffle 213 can push the water flow forward to facilitate the suction port 21b to have sufficient water flow for suction and improve the cleaning effect. In addition, the collection baffle 213 can also clean the pool wall to a certain extent, thereby improving the cleaning effect. In the embodiment, when cleaning the water side wall, when the suction port 21b is exposed to the water surface, the collection baffle 213 can also push the water flow to the suction port 21b for suction, so that the time for the suction port 21b to fail can be slowed down. Exemplarily, the collection baffle 213 is a flexible sheet, which can be deformed when it contacts the pool wall, so as to avoid affecting the travel of the cleaning robot 100 and can clean the pool wall to a certain extent.

[0061] As shown, Figure 1 In the embodiment of the present application, the collection baffle 213 includes a first baffle 2131 and two second baffles 2132, the two second baffles 2132 are respectively connected to the two ends of the first baffle 2131, the first baffle 2131 extends perpendicularly to the direction of travel of the cleaning robot 100, and the two second baffles 2132 respectively extend from the two ends of the first baffle 2131 to the direction of travel of the cleaning robot 100 and extend to the two ends of the receiving device 20 perpendicular to the direction of travel of the cleaning robot 100. The first baffle 2131 and the second baffles 2132 at both ends can surround the suction port 21b forward, so as to push the water flow around the suction port 21b towards the suction port 21b, further enabling the suction port 21b to have sufficient water flow for suction and improving the cleaning effect. In the embodiment, when cleaning the water side wall, when the suction port 21b is exposed to the water surface, the first baffle 2131 and the two second baffles 2132 can store a part of the water body for the suction port 21b to suck, so as to slow down the time for the suction port 21b to fail.

[0062] As shown, Figure 1As shown, in the embodiment of the present application, the bottom of the storage device 20 is provided with a negative pressure groove 21d, the negative pressure port 21c is formed on the groove side wall of the negative pressure groove 21d, and the negative pressure baffle 211 is connected to the negative pressure port 21c on one side of the groove bottom wall of the negative pressure groove 21d. The negative pressure groove 21d can limit the negative pressure baffle 211 to a certain extent, avoid the negative pressure baffle 211 from swinging too much, and cause the situation that it is difficult to recover, for example, avoid the negative pressure baffle 211 from deforming too much and causing permanent deformation that is difficult to recover. Exemplarily, the negative pressure groove 21d is an inverted trapezoidal groove, the width of the opening of the negative pressure groove 21d along the direction of travel of the cleaning robot 100 is greater than the groove bottom, and the negative pressure port 21c is formed on the side wall of the negative pressure groove 21d on the front side in the direction of travel of the cleaning robot 100. In this way, when the side wall of the pool is cleaned, after the negative pressure baffle 211 opens the negative pressure port 21c, the negative pressure port 21c is actually inclined downward to the side wall of the pool, which can facilitate the negative pressure port 21c to suck the water flow, and the flow of the water body will not be affected by the negative pressure groove 21d. Exemplarily, the bottom of the storage device 20 is provided with a negative pressure groove 21d on each side perpendicular to the direction of travel of the cleaning robot 100, the groove side wall of each negative pressure groove 21d is formed by the negative pressure port 21c, and the bottom of each negative pressure groove 21d is connected with the negative pressure baffle 211. By dividing the negative pressure baffles 211 into multiple parts, the weight of each negative pressure baffle 211 can be reduced, so that the negative pressure port 21c can be covered when the storage cavity is under negative pressure.

[0063] As Figures 1 to 4 shown, in the embodiment of the present application, the storage device 20 includes a first storage box 21 and a second storage box 22 connected in sequence, the first storage box 21 and the second storage box 22 are arranged in sequence from the bottom to the top of the storage device 20, the first storage box 21 is provided with a first storage cavity 21a, the suction port 21b and the negative pressure port 21c are arranged in the first storage box 21 and communicate with the first storage cavity 21a, the second storage box 22 is provided with a second storage cavity 22a, and the filter port 22b is arranged in the second storage box 22 and communicates with the second storage cavity 22a, the first storage cavity 21a and the second storage cavity 22a are communicated to form a storage cavity. When the suction device 80 sucks the water flow through the suction port 21b, the water flow and the garbage carried in the water flow will enter the collection cavity, and the garbage will be retained in the second storage cavity 22a under the blockage of the first filter screen 221 of the filter port 22b, especially under the action of suction. It should be noted that if there is too much garbage at the first filter screen 221, the filter port 22b may be blocked, thereby affecting the efficiency of garbage suction. In the embodiment, the first storage box 21 and the second storage box 22 are arranged in sequence from the bottom to the top of the storage device 20, the cleaning robot 100 can control the movement of the cleaning robot 100 and / or the operation of the suction device 80, so that the garbage retained in the second storage cavity 22a will fall into the first storage cavity 21a, thereby avoiding the situation that the garbage is blocked at the first filter screen 221, thereby affecting the suction efficiency.

[0064] As shown in the drawings, Figures 1 to 4 In the embodiment of the present application, the second storage box 22 is located at the front side of the first storage box 21 along the direction of travel of the cleaning robot 100. When the cleaning robot 100 is cleaning the side wall of the pool, the water flow is sucked through the suction port 21b, and the garbage is collected in the process, the garbage in the second storage cavity 22 can move to the area at the rear of the storage device 20 under the action of gravity, so as to avoid the garbage from blocking at the first filter screen 221, thereby affecting the suction efficiency.

[0065] As shown in the drawings, Figures 1 to 4 In the embodiment of the present application, the suction port 21b is located at the front side of the first storage box 21 along the direction of travel of the cleaning robot 100, and the negative pressure port 21c is located at the rear side of the first storage box 21 along the direction of travel of the cleaning robot 100. In this way, on the one hand, the suction port 21b can be close to the filter port 22b, so as to reduce the path of the water flow, thereby improving the suction degree of the suction port 21b when the suction device 80 sucks the water flow through the suction port 21b, and further improving the cleaning effect on the pool wall. On the other hand, the first storage cavity 21a has an area at the rear of the storage device 20, which can accommodate the collected garbage when the garbage is collected in the collection cavity, so that the accommodated garbage is not on the water flow path from the suction port 21b to the filter port 22b, and the garbage collected in the collection cavity can avoid affecting the efficiency of the suction device 80 sucking the water flow through the suction port 21b.

[0066] As shown in the drawings, Figures 2 to 4 In the embodiment of the present application, the first storage cavity 21a further has a suction passage 214 communicating with the suction port 21b, and the opening of the suction passage 214 faces the second storage cavity 22a. In this way, the water flow can be guided through the suction passage 214, so that the water flow sucked by the suction port 21b can directly reach the second storage cavity 22a and be sucked out by the suction device 80 through the filter port 22b. The path of the water flow can be further reduced, the suction degree of the suction port 21b can be improved, and the cleaning effect on the pool wall can be further improved.

[0067] As shown in the drawings, Figures 2 to 4 In the embodiment of the present application, the first storage cavity 21a is provided with a suction flap 215, which is swingably arranged at the opening of the suction passage 214 to cover or open the opening of the suction passage 214. When the suction device 80 sucks to form negative pressure in the storage cavity, the pressure outside the storage cavity is greater than that in the storage cavity, which will push the suction flap 215 open, so that the water flow can flow from the suction port 21b. It should be noted that if the pressure in the storage cavity is greater than the external pressure, the suction flap 215 can cover the opening of the suction passage 214, which can prevent the garbage accommodated in the storage cavity from flowing out from the suction passage 214, and ensure effective garbage collection.

[0068] As shown in Figures 2 to 4 the second receiving cavity 22a has a rear side wall extending rearward from the top to the bottom of the receiving device 20. Such arrangement can facilitate the garbage in the second receiving cavity 22a to move to the first receiving cavity 21a, avoiding the garbage to block at the first filter screen 221, affecting the suction efficiency. For example, when the cleaning robot 100 travels on the water side wall for cleaning, the rear side wall of the second receiving cavity 22a is inclined downward to the first receiving cavity 21a, and the garbage in the second receiving cavity 22a can slide along the rear side wall until the rear side of the first receiving cavity 21a.

[0069] As shown in Figures 1 to 4 the second receiving cavity 22a has a rear side wall extending rearward from the top to the bottom of the receiving device 20. Such arrangement can facilitate the garbage in the second receiving cavity 22a to move to the first receiving cavity 21a, avoiding the garbage to block at the first filter screen 221, affecting the suction efficiency. For example, when the cleaning robot 100 travels on the water side wall for cleaning, the rear side wall of the second receiving cavity 22a is inclined downward to the first receiving cavity 21a, and the garbage in the second receiving cavity 22a can slide along the rear side wall until the rear side of the first receiving cavity 21a.

[0070] In the embodiments of the present application, the cleaning robot 100 can control the movement of the cleaning robot 100 and / or the operation of the suction device 80 according to the suction state of the suction device 80 and the working state of the cleaning robot 100, to remove the garbage attached to the first filter screen 22b, ensure the effective suction of the suction device 80, and ensure effective garbage collection.

[0071] Specifically, the first information can be used to obtain the suction state of the suction device 80, and the second information can be used to obtain the working state of the cleaning robot 100. For example, the first information can be the water amount discharged by the suction device 80 or the water amount sucked by the suction port 21b, or the water pressure discharged by the suction device 80 or the water pressure sucked by the suction port 21b. The second information can be the inclination angle of the cleaning robot 100 detected by the inclination sensor.

[0072] In some embodiments, when cleaning the bottom wall of the water pool, the first information and the second information are obtained, when it is determined through the first information that the water suction amount is lower than the set threshold, and it is determined through the second information that the inclination angle of the cleaning robot 100 is within the preset range of the horizontal angle, the suction device 80 is controlled to stop working, and the garbage attached to the first filter screen 221 in the second receiving cavity 22a will fall under the loss of the suction force, so that at least part of the garbage falls into the first receiving cavity 21a. In this way, the garbage attached to the first filter screen 221 can be cleaned in time, avoiding the blockage of the water flow and affecting the suction efficiency of the suction device 80.

[0073] In some embodiments, when cleaning the bottom wall of the pool, after controlling the suction device 80 to stop working, the suction device 80 is further controlled to operate reversely, so that the suction device 80 can suck external water flow into the storage cavity, and realize back flushing, so as to better flush the garbage attached to the first filter screen 221, and flush the garbage into the first storage cavity 21a.

[0074] In some embodiments, when cleaning the bottom wall of the pool, after controlling the suction device 80 to stop working, the cleaning robot 100 can be further controlled to accelerate forward, so that the garbage attached to the first filter screen 221 is thrown out to the rear side region of the first storage cavity 21a by acceleration.

[0075] In some embodiments, when cleaning the bottom wall of the pool, after controlling the suction device 80 to stop working, the cleaning robot 100 can be further controlled to move towards the side wall of the pool, and one end of the cleaning robot 100 abuts against the side wall of the pool and climbs upward, and the other end abuts against the bottom surface, so that the cleaning robot 100 is in an inclined state, and the garbage is moved into the first storage cavity 21a by gravity. For example, the garbage is moved to the rear side region of the first storage cavity 21a.

[0076] In some embodiments, when cleaning the side wall of the pool, the first information and the second information are acquired, and when it is determined through the first information that the water suction amount is lower than a set threshold value, and it is determined through the second information that the inclination angle of the cleaning robot 100 is within a preset range of the vertical angle, the suction device 80 is controlled to stop working, and the cleaning robot 100 will fall to the bottom wall of the pool. It should be noted that in this embodiment, the cleaning robot 100 still sucks water flow through the suction device 80 and collects garbage, and when the water suction amount is lower than a certain threshold value, it indicates that the attached garbage on the first filter screen 221 blocks the water flow, and therefore cleaning is urgently needed. In this embodiment, an intermittent working mode can be adopted, so that the cleaning robot 100 constantly falls downward and upward, and the garbage attached to the first filter screen 221 is thrown off and thrown out to the rear side region of the first storage cavity 21a by the acceleration of the cleaning robot 100 accelerating upward and the impact of contacting the bottom wall of the pool.

[0077] In yet some embodiments, when cleaning the side wall of the pool, the cleaning robot 100 is controlled to reach the bottom of the side wall, for example, the cleaning robot 100 can be controlled to fall to the bottom wall of the pool, and one end of the cleaning robot 100 abuts against the side wall of the pool and climbs upward, and the other end abuts against the bottom surface, so that the cleaning robot 100 is in an inclined state, and the garbage is moved into the first storage cavity 21a by gravity. For example, the garbage is moved to the rear side region of the first storage cavity 21a.

[0078] As Figure 1 and Figure 2As shown, the bottom of the storage device 20 is also provided with a handle 23. The handle 23 is provided to facilitate the taking and disassembling of the storage device 20, and to facilitate user use. For example, it is convenient for the user to take out from the cleaning robot 100 to clean the garbage inside the storage device 20. Exemplarily, the handle 23 is located between the two negative pressure grooves 21d.

[0079] As shown, Figure 1 and Figure 2 As shown, the handle 23 is provided with a lock structure 24, the lock structure 24 includes an unlocking part 241 and a lock tongue 242, the unlocking part 241 and the lock tongue 242 are movably arranged on the handle 23, the unlocking part 241 is connected with the lock tongue 242 to drive the lock tongue 242 to move, the lock tongue 242 can protrude from the storage device 20 or be accommodated in the storage device 20, and the lock tongue 242 is used to correspond to the bayonet of the cleaning robot 100; in the case that the lock tongue 242 protrudes from the storage device 20, the lock tongue 242 can be clamped in the bayonet of the cleaning robot 100. After the storage device 20 is installed, the lock tongue 242 can be clamped in the bayonet of the cleaning robot 100, so that the storage device 20 can be stably fixed on the cleaning robot 100, to facilitate stable garbage collection and stable water flow suction of the suction device 80. When it is needed to take down the storage device 20 from the cleaning robot 100, the user can hold the handle 23 and move the unlocking part 241 to drive the lock tongue 242 to move, and then the lock tongue 242 is accommodated in the storage device 20, the lock tongue 242 is separated from the bayonet, and then the storage device 20 can be taken down from the cleaning robot 100, which facilitates cleaning of the storage device 20 or installation of other storage devices 20 according to needs. Exemplarily, the lock structure 24 also includes a resilient member 243, the resilient member 243 is arranged in the storage device 20 and connected with the lock tongue 242, and the resilient member 243 applies a force to the lock tongue 242 to protrude from the storage device 20, so that the lock tongue 242 can stably protrude from the storage device 20 when there is no external force, and the storage device 20 can be stably assembled on the cleaning robot 100. Exemplarily, the lock structure 24 is arranged on the bottom rear side of the storage device 20, and the lock tongue 242 protrudes from the rear side of the storage device 20.

[0080] As shown, Figure 2 and Figure 5As shown in the drawings, in the embodiment of the present application, the storage device 20 comprises a first shell 201 and a second shell 202, one end of the first shell 201 and one end of the second shell 202 are hinged, and the first shell 201 and the second shell 202 enclose a storage cavity. In this way, the user can open the first shell 201 and the second shell 202 according to the need, so as to facilitate the cleaning of the garbage in the storage cavity, or the first shell 201 and the second shell 202 can also be closed to form a storage cavity for garbage collection. Exemplarily, the second shell 202 comprises part of the shell of the aforementioned second storage box 22 and the first storage box 21, and the first shell 201 comprises part of the shell of one side of the bottom of the aforementioned first storage box 21. In this way, after the first shell 201 and the second shell 202 are opened, the first storage cavity 21a and the second storage cavity 22a are exposed, which facilitates garbage cleaning.

[0081] As shown in the drawings, Figure 2 and Figure 5 In the embodiment of the present application, the other end of the first shell 201 and the other end of the second shell 202 are detachably connected. Specifically, the other end of the first shell 201 is provided with a clamping block 2011, and the other end of the second shell 202 is provided with an elastic buckle 2021. By embedding the clamping block 2011 in the elastic buckle 2021, the stable connection of the other end of the first shell 201 and the other end of the second shell 202 can be realized, so as to ensure the sealing of the storage cavity. Exemplarily, the front end of the first shell 201 and the front end of the second shell 202 are rotatably connected, and the rear end of the first shell 201 and the rear end of the second shell 202 are detachably connected.

[0082] As shown in the drawings, Figure 1 and Figure 6 The present application also provides a cleaning robot 100, which comprises a main machine and a storage device 20. The bottom of the main machine is provided with a mounting cavity, the main machine is provided with a suction device 80, the storage device 20 is mounted in the mounting cavity, and the filter port 22b is communicated with the suction device 80. The mounting cavity is used to stably mount the storage device 20, and the suction of the suction device 80 can apply a pressure to the main machine towards the pool wall, so as to ensure that the cleaning robot 100 can be attached to the pool wall and will not slide off, and stable cleaning of the pool wall can be realized. Exemplarily, the suction device 80 is a water pump.

[0083] As shown in the drawings, Figure 1 and Figure 6As shown, in the embodiment of the present application, the installation cavity includes a first cavity 10b and a second cavity 10c in communication, and the first cavity 10b and the second cavity 10c are sequentially arranged from the bottom to the top of the cleaning robot 100. When the storage device 20 is installed, the first storage box 21 is placed in the first cavity 10b, and the second storage box 22 is placed in the second cavity 10c. In this way, the storage device 20 can be accommodated in the cleaning robot 100, the space of the cleaning robot 100 is fully utilized, the volume of the cleaning robot 100 is reduced, and the movement cleaning of the cleaning robot 100 is facilitated.

[0084] As shown in Figure 1 , Figure 6 and Figure 7 , in the embodiment of the present application, the main body 10 has a bottom plate, the first cavity 10b is located on the outer side of the bottom plate away from the main body 10, and the second cavity 10c is located on the inner side of the bottom plate towards the main body 10. Specifically, in the embodiment, the main body 10 includes a bottom disc 12 and a top shell 11, and the side of the bottom disc 12 away from the main body 10 is configured to form the bottom plate. The bottom plate is provided with two installation pieces 121 protruding relative to the bottom plate, the two installation pieces 121 are distributed at intervals and extend along the direction of travel of the main body 10, and a water guide groove 10a is formed between the bottom plate and the two installation pieces 121. The first cavity 10b is located in the water guide groove 10a. Through the water guide groove 10a, it can be ensured that the garbage carried by the water flow can be quickly collected, so as to improve the cleaning efficiency of the cleaning robot 100.

[0085] As shown in Figure 1 , Figure 6 and Figure 7 , in the embodiment of the present application, the water guide groove 10a is provided with a second blocking piece 123 and a first blocking piece 122 arranged at intervals along the direction of travel of the cleaning robot 100, and the first blocking piece 122, the second blocking piece 123 and the two installation pieces 121 on the sides form the first cavity 10b. It should be noted that the first blocking piece 122 is located on the front side of the second blocking piece 123. The bottom surface of the water guide groove 10a forms the second cavity 10c in the groove body in the main body 10. Exemplarily, when the storage device 20 is installed, the second storage box 22 is placed in the second cavity 10c, the bottom surface of the water guide groove 10a abuts against the top surface of the first storage box 21, the installation pieces 121 on the two sides abut against the two sides of the first storage box 21, and the first blocking piece 122 and the second blocking piece 123 abut against the front and rear sides of the first storage box 21, so as to stably install the storage device 20. In addition, in this embodiment, the side wall of the first cavity 10b towards the second blocking piece 123 is provided with a bayonet, so as to cooperate with the lock tongue 242 of the storage device 20, and the storage device 20 is stably installed in the installation cavity.

[0086] As shown in Figure 7 and Figure 8As shown, in the embodiment of the present application, the cleaning robot 100 is also provided with a water outlet 80a, the suction device 80 sucks water and can be discharged from the water outlet 80a, and the water outlet 80a is located on the side of the cleaning robot 100 away from the bottom. When discharging water, the water outlet 80a can apply a reaction force to the cleaning robot 100 to apply a pressure to the cleaning robot 100 towards the pool wall when cleaning the pool wall, so as to ensure that the cleaning robot 100 can stably move for cleaning. In particular, when cleaning the pool side wall, the cleaning robot 100 can be stably attached to the pool side wall and is not easy to fall off, so as to ensure that the cleaning robot 100 can stably move for cleaning on the pool side wall.

[0087] As shown, Figures 6 to 8 As shown, in the embodiment of the present application, the bottom surface of the cleaning robot 100 is provided with a track 60, and the track 60 is used to abut against the pool wall to drive the cleaning robot 100 to walk. Through the rolling of the track 60, the cleaning robot 100 can be stably attached to the pool wall to walk, so as to facilitate the movement for cleaning. Moreover, when cleaning the pool side wall, the track 60 can provide an upward driving force to the cleaning robot 100 to walk upward and clean. Of course, in other embodiments, the cleaning robot 100 can also move for cleaning on the pool wall by setting a roller.

[0088] As shown, Figures 6 to 8 As shown, in the embodiment of the present application, the cleaning robot 100 further comprises a driving device 30 and a rotating member, the driving device 30 is arranged on the main body 10, and the rotating member is rotatably arranged on the bottom of the main body 10. The driving device 30 is drivingly connected to the rotating member to drive the rotating member to rotate along the walking direction of the main body 10. Through the rotating member, the water flow or the garbage can be stirred, so as to facilitate the movement of the cleaning robot 100, or the garbage collection speed can be accelerated to improve the cleaning efficiency.

[0089] As shown, Figures 6 to 8 As shown, in the embodiment of the present application, the rotating member at least comprises a first rotating member 40 and a second rotating member 50, and the first rotating member 40 and the second rotating member 50 are respectively located on the front side and the rear side of the storage device 20 in the walking direction of the cleaning robot 100. The first rotating member 40 is located on the front side of the main body 10 and can first contact the water flow compared with the storage device 20. The first rotating member 40 can stir the garbage to quickly stir the garbage carried by the water flow to the suction port, improve the cleaning efficiency, or wipe the pool wall to improve the cleaning effect. For example, when cleaning underwater, the first rotating member 40 can contact the pool wall to wipe the pool wall or stir the garbage carried in the water flow. The second rotating member 50 can accelerate the flow rate of the water flow by stirring the water flow to improve the cleaning efficiency, and also can drive the movement of the cleaning robot 100.

[0090] In some embodiments, the first rotating member 40 can also be used to stir the water flow. In this way, the first rotating member 40 can also accelerate the flow of the water flow. And / or, the second rotating member 50 can also be used to wipe the pool wall. For example, when cleaning underwater, the pool wall can be contacted to further clean the pool wall in combination with the first rotating member 40 to improve the cleaning effect.

[0091] As shown in Figures 6 to 8 the first rotating member 40 rotates around the first rotating axis, and the second rotating member 50 rotates around the second rotating axis. The first rotating axis and the second rotating axis are both perpendicular to the advancing direction of the cleaning robot 100, and the rotating directions of the first rotating member 40 and the second rotating member 50 are the same. When the water flow flows, the first rotating member 40 and the second rotating member 50 will both rotate along the flow direction of the water flow, so that the first rotating member 40 can at least stir the garbage to the storage device 20 along the flow direction of the water flow, and the second rotating member 50 can at least stir the water flow along the flow direction of the water flow to accelerate the flow rate of the water flow. The rotating directions of the first rotating member 40 and the second rotating member 50 are the same, which can ensure that both of them can rotate along the flow direction of the water flow when the cleaning robot 100 advances, avoiding the moving resistance caused by different rotating directions of the two rotating members. It should be noted that the first rotating member 40 and the second rotating member 50 of the present application can rotate clockwise in the same direction, or can rotate counterclockwise in the same direction, depending on the specific use of the cleaning robot 100.

[0092] As shown in Figure 8 and Figure 9 the cleaning robot 100 further comprises a transmission mechanism 70 arranged on the main body 10. The transmission mechanism 70 is in transmission connection with the first rotating member 40 and the second rotating member 50 respectively, so as to drive the first rotating member 40 and the second rotating member 50 to rotate in the same direction. When the transmission mechanism 70 operates, the first rotating member 40 and the second rotating member 50 can be driven to rotate at the same time, and they must rotate in the same direction at the same time, or stop at the same time, so as to ensure that the first rotating member 40 and the second rotating member 50 can rotate in the same direction along the flow direction of the water flow. It can avoid the situation that the first rotating member 40 and the second rotating member 50 rotate in opposite directions, or the situation that one of the first rotating member 40 and the second rotating member 50 rotates and the other stops.

[0093] In the embodiment of the present application, the transmission mechanism 70 can be arranged on any one side of the two sides of the main body 10, or the transmission mechanism 70 can be arranged on both sides of the main body 10.

[0094] As shown in Figure 8 and Figure 9As shown, in the embodiment of the present application, the transmission mechanism 70 comprises a front annular tooth 71, a rear annular tooth 72, an intermediate transmission member 75, a first rotating tooth 73 and a second rotating tooth 74. The front annular tooth 71 and the first rotating tooth 73 are located at the front end of the main body 10, and the rear annular tooth 72 and the second rotating tooth 74 are located at the rear end of the main body 10. The inner side of the front annular tooth 71 is engaged with the first rotating tooth 73, and the first rotating tooth 73 is connected with the first rotating member 40. The inner side of the rear annular tooth 72 is engaged with the second rotating tooth 74, and the second rotating tooth 74 is connected with the second rotating member 50. The front annular tooth 71 and the rear annular tooth 72 are transmission-connected through the intermediate transmission member 75. The transmission of the intermediate transmission member 75 enables the front annular tooth 71 and the rear annular tooth 72 to rotate in the same direction, and thus the first rotating member 40 and the second rotating member 50 can rotate in the same direction through the transmission mechanism 70. Exemplarily, the intermediate transmission member 75 is a transmission belt which surrounds and engages with the front annular tooth 71 and the rear annular tooth 72. In other examples, the intermediate transmission member 75 can also be an even number of gears which sequentially engage with the outer side of the front annular tooth 71 and the outer side of the rear annular tooth 72.

[0095] As shown in Figure 10 and Figure 11 In the embodiment of the present application, the first rotating member 40 at least partially protrudes from the bottom of the main body 10 to wipe the surface of the area to be cleaned when cleaning underwater, and the second rotating member 50 is located in the mounting space defined by the bottom of the main body 10. When cleaning underwater, the first rotating member 40 can wipe the surface of the area to be cleaned by rotating to improve the cleaning effect, and the second rotating member 50 is located in the mounting space defined by the bottom of the main body 10, so the second rotating member 50 will not contact the surface of the area to be cleaned and will not hinder the movement of the cleaning robot 100, which is conducive to the movement of the cleaning robot 100 for cleaning underwater. Exemplarily, the first rotating member 40 is partially located in the water guide groove 10a and partially located outside the water guide groove 10a, and the second rotating member 50 is entirely located in the water guide groove 10a. In this embodiment, when cleaning underwater, the tangent line of the first rotating member 40 away from the cleaning surface end of the first rotating member 40 when rotating is opposite to the direction of travel of the main body 10, and the tangent line of the first rotating member 40 toward the cleaning surface end is toward the direction of travel of the main body 10. In this way, the first rotating member 40 can move the garbage wiped or pushed toward the storage device 20, which is conducive to the collection of garbage by the storage device 20.

[0096] As shown in Figure 10 In the embodiment of the present application, the first rotating member 40 also at least partially protrudes from the front end of the main body 10. When cleaning underwater, and the cleaning robot 100 travels to the side wall from the bottom wall of the pool, the first rotating member 40 protruding from the front end and the bottom can simultaneously wipe the bottom wall and the side wall of the pool, so as to fully wipe the bottom wall and the side wall of the pool, Figure 10Area A1 in this embodiment refers to the cleaning dead corner where the first rotating member 40 protrudes from the front end of the main body 10 when cleaning the bottom and side walls of the water tank. Figure 11 Area A2 in the figure represents the cleaning dead corner where the first rotating member 40 does not protrude from the front end of the main body 10 when cleaning the bottom and side walls of the water tank. It can be seen that this embodiment can reduce cleaning dead corners and improve the cleaning effect of the water tank.

[0097] like Figure 10 As shown in this embodiment, the cleaning robot 100 has a semicircular portion 102 at the front end of the side wall of the water guide trough 10a. Exemplarily, the radius of this semicircular portion 102 corresponds to the semicircle enclosed by the track 60 fitted over the front annular tooth 71. The center of the projection of the first rotating member 40 onto the semicircular portion 102 is O1, and the center of the semicircular portion 102 is O2. O1 is located on the front and bottom sides of the cleaning robot 100 facing O2. When cleaning on the underwater horizontal surface, the angle between the line connecting O1 and O2 and the horizontal plane is 40-50°, exemplarily 45°. This ensures that the contact amount between the first rotating member 40 and the side wall is consistent with the contact amount between the first rotating member 40 and the bottom wall, minimizing cleaning dead angles. Furthermore, as the cleaning robot 100 moves toward the side wall, that is, during the process of contacting the side wall, tilting toward the side wall, and moving until it is in contact with the side wall, the first rotating component 40 can wipe from the bottom wall to the side wall and from the side wall from bottom to top, so as to thoroughly clean the dead corners of the pool and improve the cleaning effect of the pool.

[0098] like Figure 8 As shown in this embodiment, the first rotating component 40 includes a first rotating shaft 41 and a cleaning brush 42. The two ends of the first rotating shaft 41 are rotatably mounted on both sides of the main body 10. The cleaning brush 42 is disposed on the first rotating shaft 41 and extends along the axial direction of the first rotating shaft 41, used to wipe the surface of the area to be cleaned during underwater cleaning. When the cleaning robot 100 moves to clean, the first rotating shaft 41 can rotate relative to the main body 10, thereby driving the cleaning brush 42 to rotate around the axis of the first rotating shaft 41, so that it can wipe the surface of the area to be cleaned and move debris during underwater cleaning, facilitating rapid debris collection. In this embodiment, the cleaning brush 42 extends along the axial direction of the first rotating shaft 41, allowing it to cover a wider area, increasing the wiping area and the area for moving debris, which is beneficial for the cleaning robot 100. For example, the first rotating shaft 41 includes two sections, the end of each section is inserted through a mounting member 121 and connected to the first rotating tooth 73 of the transmission mechanism 70 in the mounting member 121. The transmission mechanisms 70 in the two mounting members 121 can drive the two ends of the first rotating shaft 41 to rotate respectively. Since the first rotating shaft 41 is segmented, the rotation of the two sections does not affect each other, which facilitates the stable rotation of the first rotating member 40.

[0099] like Figure 10As shown, in some embodiments, the distance between the center of the first rotating member 40 and the end of the cleaning brush 42 is greater than the distance between the center of the first rotating member 40 and the intersection between the vertical surface of the front end of the main body 10 and the bottom surface, that is, greater than the radius of the first rotating shaft 41. Figure 10 As shown, the length of the line connecting O1 to K is greater than the distance between the center of the first rotating member 40 and the bottom or front end of the main body 10. It should be noted that the cleaning brush 42 is flexible and can be deformed when it contacts the pool wall. In this way, when the cleaning robot 100 is cleaning underwater and travels to the side wall from the bottom wall of the pool, the cleaning brush 42 can brush the corner of the bottom wall and the side wall of the pool, and the first rotating shaft 41 will not affect the travel of the cleaning robot 100, which can further clean the dead corners of the pool and improve the cleaning effect of the pool.

[0100] As shown in FIG. 1, the cleaning robot 100 further comprises a driving device 30 and a transmission mechanism 70. Figure 8 As shown, in the embodiments of the present application, the second rotating member 50 comprises a second rotating shaft 51 and a plurality of paddles 52. The two ends of the second rotating shaft 51 are rotatably mounted on the two sides of the main body 10 and are connected with the driving device 30. The plurality of paddles 52 are uniformly arranged along the outer surface of the second rotating shaft 51 and can provide a certain driving force to the cleaning robot 100.
