[0036] like Figures 1 to 7 As shown, the utility model provides a cleaning device, which may be a floor scrubber or a cleaning robot. The following embodiments are illustrated by taking a cleaning robot as an example. The cleaning robot includes a housing assembly, a cover plate 200, a sewage storage element 300 and a limiting structure.

[0037] The description is based on the position of the cleaning robot when it is placed on the ground for work. The housing assembly has a receiving cavity, and the sewage storage component 300 is located in the receiving cavity. The receiving cavity is provided with a first opening facing downward, that is, the first opening faces the ground, and the sewage storage component 300 can fall to the ground from the first opening. The sewage storage component 300 is located in the receiving cavity, and the sewage storage component 300 is provided with a pressing portion 320, and a portion of the pressing portion 320 can pass through and be exposed to the housing assembly; a limiting structure is provided between the housing assembly and the sewage storage component 300, and is used to limit the movement of the sewage storage component 300 relative to the housing assembly; the limiting structure can be unlocked by pressing the pressing portion 320.

[0038] The specific action process of the cleaning robot 100 in the above embodiment is as follows: the user presses the pressing part 320 toward the accommodating cavity, and the sewage storage component 300 moves toward the accommodating cavity. The movement stroke of the sewage storage component 300 is sufficient to release the limiting structure. At this time, the sewage storage component 300 will fall to the ground from the first opening under the action of gravity, and then the outer shell assembly can be lifted to remove the sewage storage component 300. The user can clean the sewage storage component 300. After cleaning the sewage storage component 300, the cleaning robot 100 can be turned over, and the sewage storage component 300 can be turned over and installed in the cleaning robot 100. Since the sewage storage component 300 is cleaned at this time, even if the sewage storage component 300 is turned over, it will not cause secondary pollution to the cleaning robot 100 or the ground.

[0039] Specifically, if Figures 1 to 3 , Figure 7As shown, in some embodiments of the present invention, the housing assembly includes a housing body 120 and a cover plate 200, the accommodating cavity is arranged in the housing body 120, the cover plate 200 is installed in the accommodating cavity, the lower part of the cover plate 200 is provided with an installation cavity 210, the installation cavity 210 is used to install the drum and the sewage storage element 300, the drum is provided with a rag 250, the lower part of the installation cavity 210 is provided with a second opening, the sewage storage element 300 can fall to the ground from the second opening, the housing body 120 is provided with an avoidance position, the avoidance position is connected to the accommodating cavity, and the cover plate 200 corresponds to the avoidance position. The empty area is the panel housing 230, which can be extended from the empty area so that the panel housing 230 is exposed from the shell body 120. The panel housing 230 is provided with an escape opening, which is connected with the installation cavity 210. The sewage storage part 300 is located in the installation cavity 210, and the limiting structure is provided between the cover plate 200 and the sewage storage part 300, and the pressing part 320 is inserted through the escape opening. The user can release the limiting structure by pressing the pressing part 320, so that the sewage storage part 300 falls from the installation cavity 210 to the ground under the action of gravity. Other components can also be installed in the installation cavity 210 of the cover plate 200, for example, a roller can be installed. The shell assembly is assembled by the shell body 120 and the cover plate 200, which can reduce the complexity of the shell body 120. At the same time, it can be more convenient to install other components in the cover plate 200 and then assemble it into the shell body 120 as a whole, reducing the difficulty of assembly. Of course, in some embodiments of the present invention, the limiting structure can also be separately provided on the housing component or the sewage storage component 300 .

[0040] The sewage storage part 300 has a sewage tank 310 for receiving sewage, the rag 250 on the drum is used to clean the floor, and the second opening of the installation cavity 210 faces the floor so that the sewage storage part 300 can enter and exit; the panel housing 230 is a part of the housing of the cover plate 200, and the other housings of the cover plate 200 are located in the shell body 120. Since the pressing part 320 can protrude from the panel housing 230, when the cleaning robot 100 is placed on the floor, the user can directly find the pressing part 320 on the shell assembly of the cleaning robot 100, thereby facilitating the user to find the pressing part 320 and press the pressing part 320.

[0041] The specific action process of the cleaning robot in the above embodiment is as follows: the user presses the pressing part 320 toward the accommodating cavity, and the sewage storage component 300 moves toward the accommodating cavity. The movement stroke of the sewage storage component 300 is sufficient to release the limiting structure. At this time, the sewage storage component 300 will fall to the ground from the second opening under the action of gravity, and then the outer shell assembly can be lifted to remove the sewage storage component 300 from the cleaning robot 100. The user can clean the sewage storage component 300. After cleaning the sewage storage component 300, the cleaning robot 100 can be turned over, and the sewage storage component 300 can be turned over and installed in the installation cavity 210 of the cover plate 200. Since the sewage storage component 300 is cleaned at this time, even if the sewage storage component 300 is turned over, it will not cause secondary pollution to the cleaning robot 100 or the ground. Of course, after the user is used to disassembling and assembling the sewage storage part 300, the user will be more familiar with the position of the limiting structure, so the cleaning robot 100 can be directly lifted. With the understanding of the limiting structure, the user can match the sewage storage part 300 with the cover plate 200 from bottom to top, and then install the sewage storage part 300 into the installation cavity 210. It can be seen that the cleaning robot of this embodiment does not need to be turned over when disassembling, thereby reducing the situation where the sewage or garbage remaining in the sewage storage part 300 falls onto the cleaning robot 100 and the ground when the cleaning robot 100 is turned over, thereby reducing the situation of causing secondary pollution.

[0042] It should be noted that the embodiments of the shell assembly are not limited to the embodiments of the shell body 120 and the cover plate 200. In some embodiments of the present invention, the shell assembly may only adopt the shell body 120, that is, the sewage storage component 300 is directly installed on the inner wall of the shell body 120, and the pressing portion 320 directly passes through the side wall of the shell body 120 and is exposed on the shell body 120. It is also possible to disassemble the sewage storage component 300 without turning over the cleaning robot 100.

[0043] like Figure 2 As shown, in some embodiments of the present invention, the avoidance position is set on the side of the shell body 120, and then the panel shell 230 is exposed on the side of the shell body 120 of the cleaning robot 100, and is located at the bottom of the shell body 120 of the cleaning robot 100, so as to facilitate the disassembly and assembly of the sewage storage component 300. The avoidance opening is set as a notch 240, and the notch 240 is located at the lower part of the panel shell 230. The pressing part 320 is inserted into the notch 240, whereby, when the pressing part 320 is pressed until the limiting structure is released, the sewage storage component 300 will fall from the second opening to the ground under the action of gravity, and the sewage storage component 300 will not be blocked by the notch 240 during the falling process, so that the sewage storage component 300 falls to the ground in a relatively stable posture, reducing the splashing of sewage in the sewage storage component 300, and the overall structure is simple and practical.

[0044] It should be noted that the panel housing 230 may also be exposed at other positions of the shell body 120 , such as the upper end of the side of the shell body 120 or the upper part of the shell body 120 , as long as it is convenient for the user to release the limiting structure by pressing the pressing portion 320 .

[0045] In addition, the notch 240 can be replaced by other structures. For example, a through hole is set on the panel shell 230. When the through hole is large enough, it can accommodate a finger to pass through. At this time, the user can use the finger to push the pressing part 320 completely out of the through hole, and the purpose of using the pressing part 320 to unlock the limiting structure can be achieved.

[0046] It can be understood that the release of the limit structure by pressing the pressing part 320 means that the stroke of pressing the pressing part 320 must be at least greater than the stroke of the limit structure, that is, along the pressing direction of the pressing part 320, the sewage storage part 300 moves a minimum distance S to enable the limit structure to switch from the limit state to the release state, and the height of the part of the pressing part 320 that passes through the notch 240 is greater than S, so that the operation of the pressing part 30 to release the limit structure is smoother. Figure 2 As shown, in some embodiments of the utility model, the stroke of the limiting structure is generally not more than 2 mm. Therefore, the height h of the part of the pressing portion 320 passing through the notch 240 can be set to 2 mm to 4 mm; when the user presses the pressing portion 320 until it is flush with the outer surface of the panel shell 230, the limiting structure can be released, which is very convenient and quick. At the same time, it reduces the formation of sharp edges on the panel shell 230 by the pressing portion 320, and reduces the probability of the pressing portion 320 being accidentally touched and the limiting structure being released.

[0047] Specifically, the pressing portion 320 can be configured to be in a rectangular parallelepiped shape, a cylindrical shape, a spherical shape, etc., as long as the pressing function can be achieved.

[0048] like Figure 3 As shown, in some embodiments of the present invention, the limiting structure includes a longitudinal limiting assembly for limiting the vertical movement of the sewage storage member 300 relative to the cover plate 200, and a transverse limiting assembly for limiting the horizontal movement of the sewage storage member 300 relative to the cover plate 200. The longitudinal limiting assembly is used to support the sewage storage member 300 so as not to fall, and the transverse limiting assembly is used to position the sewage storage member 300 in a horizontal plane to prevent the sewage storage member 300 from moving in the horizontal direction and causing the longitudinal limiting assembly to fail to support. The transverse limiting assembly and the longitudinal limiting assembly can cooperate to limit the position of the sewage storage member 300, and the longitudinal limiting assembly and the transverse limiting assembly can cooperate to form a good support and positioning for the sewage storage member 300, thereby ensuring working stability.

[0049] From a structural point of view, the lateral limit assembly and the longitudinal limit assembly can be set independently or integrated together.

[0050] Specifically, if Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments of the utility model, the transverse limiting assembly includes two positioning grooves 410 and two first protrusions 420, the positioning grooves 410 are arranged on the outer side wall of the sewage storage element 300, and the first protrusions 420 are arranged on the inner side wall of the installation cavity 210. In this case, the transverse limiting assembly is independently arranged, the installation cavity 210 has two sections of inner side walls arranged in parallel, and the two first protrusions 420 are respectively arranged on the inner side walls of the two sections of the installation cavity 210 arranged in parallel, and the sewage tank 310 body is correspondingly provided with two parallel outer side walls, whereby the sewage tank 310 body can be closely matched with the inner side wall of the installation cavity 210, the first protrusion 420 extends in the horizontal direction, and the first protrusion 420 is inserted into the positioning groove 410 to limit the horizontal position of the sewage storage element 300, and the overall structure of the above-mentioned transverse limiting assembly is simple and practical.

[0051] Specifically, the installation cavity 210 has two parallel inner side walls, and a middle section 430 is provided on the inner side wall. The middle section 430 is independently protruded, and thus the middle section 430 has a certain elasticity. The first protrusion 420 is provided on the middle section 430, and the elasticity of the middle section 430 is utilized to enable the first protrusion 420 to enter and exit the positioning groove 410. Specifically, the positioning groove 410 can be opened outward and downward to facilitate processing.

[0052] It should be noted that the positioning groove 410 and the first protrusion 420 are not necessarily arranged on the sewage storage element 300 and the inner wall of the installation cavity 210 in a corresponding manner, and they can be adjusted according to actual conditions.

[0053] For example, the positioning groove 410 can be provided on the inner side wall of the installation cavity 210, and the first protrusion 420 can be provided on the sewage storage member 300, which can also form a horizontal position limit for the sewage storage member 300. In addition, the number of the positioning grooves 410 and the first protrusions 420 can also be selected according to actual needs. If the cleaning robot 100 vibrates greatly during operation, three or more positioning grooves 410 and three or more first protrusions 420 can be selected to enhance the limiting effect of the lateral limiting assembly on the sewage storage member 300 and the cover plate 200, thereby ensuring the normal operation of the cleaning robot 100.

[0054] Specifically, if Figures 3 to 6As shown, in some embodiments of the present invention, the longitudinal limit assembly is independently provided, and the longitudinal limit assembly includes two support plates 510 and two protrusions 520. The support plate 510 is protrudingly provided on the inner side wall of the installation cavity 210, and the support plate 510 is generally in the shape of a horizontal plane. The protrusion 520 is provided on the side end of the sewage storage part 300 away from the pressing part 320.

[0055] The two sections of inner side walls arranged in parallel on the installation cavity 210 are connected with two sections of inner side walls extending outward at the end away from the notch 240, and the distance between the two sections of inner side walls extending outward is greater than the distance between the two sections of inner side walls arranged in parallel. Two support plates 510 are arranged at the lower part of the two sections of inner side walls extending outward for supporting the protrusions 520. Similarly, the two protrusions 520 on the sewage storage part 300 are also arranged at the end away from the pressing part 320, and the two protrusions 520 extend outward relative to the two parallel outer side walls on the sewage tank 310 body.

[0056] When the pressing part 320 and the notch 240 are assembled, a part of the protrusion 520 is located on the support plate 510, and the support plate 510 and the inner side of the panel shell 230 support the sewage storage component 300. After the user presses the pressing part 320 into place, the protrusion 520 moves with the sewage storage component 300 to the outside of the support plate 510. At this time, the support plate 510 no longer supports the sewage storage component 300. The sewage storage component 300 falls under the action of gravity and separates from the cleaning robot 100.

[0057] It should be noted that the number of support plates 510 and protrusions 520 can also be selected according to actual needs. If the weight of the sewage storage component 300 is large, three or more support plates 510 and three or more protrusions 520 can be selected to enhance the supporting effect of the longitudinal limiting component on the sewage storage component 300 and ensure the normal operation of the cleaning robot 100.

[0058] In order to further improve the vertical support stability of the sewage storage member 300, in some embodiments of the present utility model, the longitudinal limiting assembly further includes two second protrusions 530 and two positioning holes 540. As shown in the figure, the positioning holes 540 are provided on the panel housing 230. The positioning holes 540 can be provided as through holes to provide better support for the second protrusions 530. The second protrusions 530 are provided on the sewage storage member 300. The second protrusions 530 are provided near the pressing portion 320. The positioning holes 540 are provided on the panel housing 230. It can be seen that the positioning holes 540 cooperate with the second protrusions 530 to vertically limit and support one end of the sewage storage member 300 near the panel housing 230, and the support plate 510 cooperates with the protrusions 520 to vertically limit and support the other end of the sewage storage member 300, that is, both ends of the sewage storage member 300 are limited and supported, so that the sewage storage member 300 is well supported in the vertical direction.

[0059] When the pressing part 320 and the notch 240 are assembled, the second protrusion 530 is inserted into the positioning hole 540, and the second protrusion 530 and the positioning hole 540 cooperate to form a support for the sewage storage component 300. After the user presses the pressing part 320 into place, the second protrusion 530 follows the sewage storage component 300 to move out of the positioning hole 540. At this time, the second protrusion 530 no longer supports the sewage storage component 300. The sewage storage component 300 falls under the action of gravity and is separated from the cleaning robot 100.

[0060] It should be noted that the positioning hole 540 and the second protrusion 530 are not necessarily arranged correspondingly on the panel shell 230 and the sewage storage component 300, and other methods can also be used. For example, the positioning hole 540 can be arranged on the sewage storage component 300, and the second protrusion 530 can be arranged on the inner side of the panel shell 230, which can also achieve support for the sewage storage component 300.

[0061] In some embodiments of the present invention, from a structural point of view, the transverse limiting assembly and the longitudinal limiting assembly can be integrated together, for example, the longitudinal limiting assembly includes a support plate 510 and a protrusion 520, the support plate 510 is protrudingly arranged on the inner side wall of the installation cavity 210, the support plate 510 is generally in the shape of a horizontal plane, and the protrusion 520 is arranged at the side end of the sewage storage member 300 away from the pressing portion 320. The two parallel inner side walls on the installation cavity 210 are connected to two inner side walls extending outward at the end away from the notch 240, and the distance between the two inner side walls extending outward is greater than the distance between the two parallel inner side walls. The two support plates 510 are arranged at the lower part of the two inner side walls extending outward, and are used to support the protrusion 520. Similarly, the two protrusions 520 on the sewage storage member 300 are also arranged at the end away from the pressing portion 320, and the two protrusions 520 extend outward relative to the two parallel outer side walls on the sewage tank 310 body. The lateral limiting assembly may include a positioning groove 410 and a first protrusion 420. The first protrusion 420 may be arranged on the support plate 510, and the positioning groove 410 may be arranged at the bottom end of the protrusion 520. Thus, structurally, the lateral limiting assembly and the longitudinal limiting assembly may be integrated on the support plate 510 and the protrusion 520, and the structure is compact.

[0062] like Figure 4As shown, in some embodiments of the utility model, a pumping area 330 is defined in the sewage tank 310 by a filtering unit, and the pumping area 330 is connected to the water inlet pipe of the water pump, and the water in the pumping area 330 is pumped into the sewage tank 110 by the water pump. The sewage tank 110 is located above the sewage storage unit 300, and the sewage tank 110 can be moved in and out of the avoidance position so as to disassemble and clean the sewage tank 110; the filtering unit includes a plurality of first columns 340, the first columns 340 are arranged at intervals, and the first columns 340 are arranged in a rectangular shape. The pumping area 330 can be completely surrounded by the first columns 340, or the pumping area 330 can be surrounded by the inner side wall of the sewage tank 310 and the first columns 340, thereby reducing the use of the first columns 340, and there is a gap between two adjacent first columns 340, through which water can flow, and some garbage can be intercepted, thereby reducing the garbage from entering the pumping area 330 and reducing the occurrence of blockage of the water inlet pipe of the water pump.

[0063] The cover plate 200 is provided with an avoidance hole 220 corresponding to the water pumping area 330 so that the water inlet pipe can enter the water pumping area 330 from the avoidance hole 220 to pump water.

[0064] It should be noted that the shape of the pumping area 330 is not limited to the above-mentioned rectangle, and it can also be circular, arched, elliptical, etc.

[0065] like Figure 4 and Figure 7 As shown, in order to further intercept the garbage, a preliminary filtering structure can be provided. In some embodiments of the utility model, a scraper rib 360 is provided at the upper end of the sewage body, which is used to scrape the water from the rag 250 on the drum. The lower part of the scraper rib 360 can be regarded as the water inlet of the sewage tank 310. A plurality of second columns 350 are provided at the water inlet of the sewage tank 310. The second columns 350 are arranged at intervals and distributed in a straight line, and are evenly distributed at the water inlet of the sewage tank 310. The gap between two adjacent second columns 350 is larger than the gap between two adjacent first columns 340. The second columns 350 arranged as above constitute a preliminary filtering structure.

[0066] The sewage scraped off from the drum by the rag 250 first flows through the gap between the second columns 350, then flows through the gap between the first columns 340, and finally reaches the pumping area 330. Larger garbage will be intercepted by the second columns 350, and smaller garbage will be intercepted by the first columns 340. The garbage of different sizes is intercepted in a graded manner, thereby reducing the problem of the gap between the first columns 340 being blocked by larger garbage, and increasing the frequency of disassembly and cleaning of the sewage tank 310.

[0067] The shapes of the first column 340 and the second column 350 are not limited, and may be other shapes such as cylinders or sheets, as long as they can play the role of intercepting garbage.

[0068] Among them, the arrangement of the second columns 350 is not limited to a straight line arrangement, and it can also be other arrangements. For example, multiple second columns 350 can form an A-shaped arrangement, with the tip of the arrangement facing the wiper rib 360, and the intercepted garbage automatically moves to both ends to ensure the filtering performance in the middle position of the preliminary filtering structure.

The dirt shielding plate is installed at the lower part of the cover plate 200. After cleaning the ground, the rag 250 first passes through the dirt shielding plate. The dirt shielding plate can reduce the occurrence of garbage carried by the rag 250 being thrown into the installation cavity 210 when the rag 250 rotates. After passing through the dirt shielding plate, the rag 250 contacts the comb plate again. The comb plate further intercepts the garbage carried by the rag 250, reducing the amount of garbage entering the next link. After the rag 250 passes through the comb plate The rag 250 continues to rotate and passes through the water spray assembly, which sprays clean water onto the rag 250 to clean the rag 250. The rag 250 then continues to rotate to the sewage storage component 300. The sewage storage component 300 is provided with a wiper rib 360, which is arranged parallel to the rag 250. When the rag 250 passes through the wiper rib 360, it will be squeezed by the wiper rib 360, and the squeezed sewage will enter the sewage storage component 300. After simple filtration by the sewage storage component 300, the sewage is finally pumped into the sewage tank 110 for storage.

[0072] The cover plate 200 is also provided with a panel housing 230, which is exposed to the outer shell body 120. The sewage storage part 300 is provided with a pressing part 320, which passes through the notch 240, and the user can directly operate the pressing part 320 outside the cleaning robot 100.
