[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0037] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0038] See also Figures 3 to 11 As shown, according to an embodiment of the present application, a cleaning device 10 is provided. The cleaning device 10 includes a main body 11, a cover plate 30 and a driving mechanism.

[0039] The main body 11 is provided with a sewage tank 12, with a sewage outlet 121 defined at its bottom. A cover plate 30 is rotatably mounted on the main body 11 via a rotating shaft 31. The cover plate 30 has a first position, in which it rotates about the rotating shaft 31 to close the sewage outlet 121, and a second position, in which the sewage outlet 121 is opened. A drive mechanism is provided on the main body 11 to rotate the rotating shaft 31, switching the cover plate 30 between the first and second positions.

[0040] Specifically, existing cleaning equipment 10, such as a floor scrubber, is provided with a sewage tank 12. The sewage tank 12 is used to collect sewage and stains generated by the floor scrubber, thereby preventing the sewage and stains from falling onto the ground again, causing the ground to be contaminated again and requiring the floor scrubber to clean the ground again, resulting in a significant reduction in the cleaning efficiency of the floor scrubber. In most existing floor scrubbers, when the sewage tank 12 is full of stains and sewage, the sewage tank 12 usually needs to be removed from the main body 11 before the sewage or stains in the sewage tank 12 can be discharged, which makes the use of the floor scrubber too cumbersome.

[0041] In this embodiment, since the bottom of the sewage tank 12 is provided with a drain outlet 121, and the main body is provided with a cover plate 30 and a rotating shaft 31, the cover plate 30 is normally in the first position to close the drain outlet 121. When it is necessary to drain the dirt and sewage in the sewage tank 12, the cover plate 30 is simply rotated from the first position to the second position via the rotating shaft 31, thereby opening the drain outlet 121 and allowing the sewage or dirt to flow out under the action of gravity. In other words, when it is necessary to drain the sewage or dirt in the sewage tank 12, there is no need to remove the sewage tank 12 from the main body 11. Instead, the dirt and sewage in the sewage tank 12 can be drained by simply connecting the drain outlet 121 to an external sewage pipe, thereby improving the convenience of draining the sewage tank 12 to a certain extent.

[0042] Furthermore, the driving mechanism includes a transmission assembly 42 and a driving assembly 41. The transmission assembly 42 is arranged between the driving assembly 41 and the rotating shaft 31. The driving assembly 41 drives the transmission assembly 42 to drive the rotating shaft 31 to rotate, so that the cover 30 switches between the first position and the second position.

[0043] Specifically, in this embodiment, the driving component 41 can be a motor, and the transmission component 42 is arranged between the motor and the rotating shaft 31. After the motor is started, it drives the transmission component 42, and the transmission component 42 drives the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 causes the cover 30 to switch between the first position and the second position.

[0044] In some embodiments, the transmission assembly 42 includes a gear transmission part 43 , the rotating shaft 31 is rotatably connected to the main body 11 , and the rotating shaft 31 passes through the cover 30 and is connected to the gear transmission part 43 , and the gear transmission part 43 is connected to the driving assembly 41 .

[0045] Specifically, the motor transmits power to the rotating shaft 31 via the gear transmission unit 43. That is, when the motor is driven, the gear transmission unit 43 rotates, and the rotating shaft 31 is connected to the gear transmission unit 43. The rotation of the gear transmission unit 43 drives the rotating shaft 31, thereby switching the cover 30 between the first position and the second position. In this embodiment, because the gear transmission unit 43 is directly connected to the rotating shaft 31, the torque applied to the gear transmission unit 43 can be directly transmitted to the rotating shaft 31. Compared to other transmission methods, the transmission method using the gear transmission unit 43 can improve force transmission efficiency and transmission stability to a certain extent.

[0046] Furthermore, in this embodiment, the drive assembly 41 includes a linear motor 411. In this embodiment, since the gear transmission unit 43 does not need to apply excessive torque to the rotating shaft 31 when the cover 30 switches between the first position and the second position, the motor in this embodiment adopts a linear motor 411. The linear motor 411 can accurately move a small distance, thereby driving the gear transmission unit 43 to rotate a small angle, ultimately allowing the cover 30 to move from the first position to the second position without being subjected to a large torque. If an ordinary motor is directly connected to the rotating shaft 31, it may be difficult to accurately control the torque output by the motor. That is, if the torque applied by the motor to the rotating shaft 31 is too large, it may cause the cover 30 to be damaged by excessive force.

[0047] Furthermore, the sewage tank 12 includes a housing and a fixing base 60 disposed at the bottom of the housing. The housing is detachably mounted on the fixing base 60, which is connected to the main body 11. The gear transmission unit 43 is disposed on the fixing base 60 and passes through the fixing base 60 to connect to the motor. In addition, in this embodiment, the rotating shaft 31 and the cover plate 30 are both fixed to the fixing base 60, and the sewage discharge hole is provided at the bottom of the housing.

[0048] As attached Figure 7 As shown, the gear transmission part 43 includes a transmission bracket 420 and a gear 423. The transmission bracket 420 is arranged between the driving component 41 and the rotating shaft 31. The transmission bracket 420 is driven by the driving component 41 along the first direction (as shown in the attached figure). Figure 11 The transmission bracket 420 reciprocates along the first direction, and a rack 4201 is provided on the transmission bracket 420 to cooperate with the gear 423. The gear 423 is sleeved on the rotating shaft 31 and meshes with the rack 4201. When the transmission bracket 420 reciprocates along the first direction, the rack 4201 drives the gear 423 to rotate so that the rotating shaft 31 rotates.

[0049] Specifically, the linear motor 411 is arranged on the main body 11 at the bottom of the fixed seat 60, and an avoidance groove 61 is opened on the fixed seat 60. The transmission bracket 420 can reciprocate along the first direction in the avoidance groove 61 under the drive of the linear motor 411. After the transmission bracket 420 moves, the rack 4201 moves along the first direction relative to the gear 423. Since the rack 4201 is engaged with the gear 423, the gear 423 rotates under the drive of the rack 4201. While the gear 423 rotates, it drives the rotating shaft 31 to rotate, and finally the cover 30 rotates.

[0050] In some embodiments, a mounting slot 4202 is defined on the transmission bracket 420 , the gear 423 is embedded in the mounting slot 4202 , the rack 4201 is disposed on the inner wall of the mounting slot 4202 , and the rack 4201 extends along the first direction.

[0051] As attached Figure 7 As shown, a mounting groove 4202 is provided on the side of the transmission bracket 420 close to the cover plate 30, a gear 423 is embedded in the mounting groove 4202, and a rack 4201 is provided on the top wall of the mounting groove 4202. The linear motor 411 drives the transmission bracket 420 to reciprocate in a first direction, so that the rack 4201 moves in the first direction relative to the gear 423, and the movement of the rack 4201 drives the gear 423 to rotate. In this embodiment, the gear 423 can be a full wheel or a half wheel. Providing a mounting groove 4202 for mounting the gear 423 on the transmission bracket 420 can improve the space utilization of the cleaning device 10 to a certain extent. In a preferred embodiment, the gear 423 is a half wheel. The volume and manufacturing cost of the half wheel are relatively low, which can improve the space utilization of the cleaning device 10 to a certain extent and reduce the manufacturing cost of the cleaning device 10 to a certain extent.

[0052] Furthermore, the sewage tank 12 is detachably connected to the main body 11; the transmission bracket 420 includes a first frame 421 and a second frame 422 that are detachably connected to each other, the first frame 421 is arranged on the sewage tank 12, and the second frame 422 and the driving assembly 41 are both arranged on the main body 11 and connected to each other.

[0053] In this embodiment, the sewage tank 12 is detachably connected to the main body 11 to facilitate maintenance of the sewage tank 12. Specifically, in this embodiment, the transmission bracket 420 includes a first frame 421 and a second frame 422 that are detachably connected to each other. The first frame 421 is disposed in the avoidance groove 61 of the fixing seat 60, the mounting groove 4202 is located on the first frame 421, and the second frame 422 is connected to the output shaft of the linear motor 411. The first frame 421 and the second frame 422 are detachably connected. That is to say, when the sewage tank 12 needs to be removed from the main body 11, since the transmission bracket 420 is divided into the first frame 421 and the second frame 422, the transmission bracket 420 will not interfere with the sewage tank 12, thereby causing the problem that the sewage tank 12 is difficult to remove from the main body 11.

[0054] Furthermore, the first frame 421 is provided with a plurality of first limiting protrusions 4211 spaced apart along the first direction, and the second frame 422 is provided with at least one second limiting protrusion 4221 . The at least one second limiting protrusion 4221 is clamped between two adjacent first limiting protrusions 4211 .

[0055] As attached Figure 9 As shown, a first limiting protrusion 4211 provided on the first frame 421 protrudes in a direction close to the linear motor 411, and a second limiting protrusion 4221 on the second frame 422 protrudes in a direction close to the fixing seat 60. In this embodiment, one second limiting protrusion 4221 is engaged between the two first limiting protrusions 4211. When the linear motor 411 drives the second frame 422 to reciprocate in the first direction, the second limiting protrusion 4221 exerts an external force on the first limiting protrusion 4211, causing the first frame 421 to follow the second frame 422 in the same direction. This further causes the rack 4201 and the gear 423 on the first frame 421 to cooperate with each other, thereby driving the rotation shaft 31. In addition, when the sewage tank 12 needs to be removed from the main body 11, the second limiting protrusion 4221 is removed from between the two adjacent first limiting protrusions 4211 to prevent interference between the sewage tank 12 and the first frame 421 during removal.

[0056] Furthermore, the driving mechanism further includes a reset portion 50 , which is disposed between the rotating shaft 31 and the main body 11 . The reset portion 50 is configured to apply an external force to the rotating shaft 31 so that the rotating shaft 31 drives the main body 11 to rotate from the second position to the first position.

[0057] Specifically, a support protrusion 62 is provided on the fixing base 60, and one end of the rotating shaft 31 is rotatably fixed to the support protrusion 62. In this embodiment, the reset portion 50 includes a torsion spring, which is provided on the rotating shaft 31. One end of the torsion spring abuts against the support protrusion 62, and the other end abuts against the fixing base 60. When the rotating shaft 31 rotates to move the cover plate 30 from the first position to the second position, the torsion spring is compressed by an external force. When the linear motor 411 removes the external force, the torsion spring applies a force to the rotating shaft 31, causing the rotating shaft 31 to rotate in the opposite direction, thereby driving the cover plate 30 from the second position to the first position, thereby closing the sewage outlet 121.

[0058] Furthermore, the main body 11 is provided with a drainage channel 111 corresponding to the drainage outlet 121. Specifically, when the cover plate 30 is moved to the second position, the drainage outlet 121 is connected to the drainage channel 111, and the dirt and sewage in the sewage tank 12 can flow out through the drainage channel 111; when the cover plate 30 is moved to the first position, the cover plate 30 closes the drainage outlet 121, and the dirt and sewage in the sewage tank 12 cannot flow out through the drainage channel 111. In one embodiment, the drainage channel 111 is provided on the fixed seat 60, and the cover plate 30 is disposed between the drainage channel 111 and the drainage outlet 121. When the cover plate 30 is moved to the second position, the cover plate 30 is located in the drainage channel 111, and the drainage channel 111 is connected to the drainage outlet 121; when the cover plate 30 is in the first position, the cover plate 30 simultaneously closes the drainage outlet 121 and the drainage channel 111.

[0059] On the other hand, the present application also provides a cleaning system, which includes the above-mentioned cleaning device 10 and a base station 20 . The base station 20 is provided with a suction channel 21 corresponding to the sewage discharge channel 111 .

[0060] As attached Figure 1 and attached Figure 2 As shown, when it is necessary to drain the dirt and sewage from the sewage tank 12, the cleaning device 10 is simply placed on the base station 20, connecting the sewage discharge channel 111 with the suction channel 21. The linear motor 411 is then activated to move the cover plate 30 from the first position to the second position, opening the sewage outlet 121. The dirt and sewage flow from the sewage discharge channel 111 into the suction channel 21. In this embodiment, a certain negative pressure is present within the suction channel 21, which can absorb the dirt and sewage from the sewage tank 12, thereby facilitating the entry of the dirt and sewage into the base station 20.

[0061] In addition, the base station 20 is also provided with a detection mechanism (not shown in the figure). The detection mechanism is used to detect whether the cleaning device 10 has returned to the base station 20. The detection mechanism can also detect whether the sewage and stains in the sewage tank 12 of the cleaning device 10 need to be discharged. The detection mechanism is electrically connected or communicatively connected to the linear motor 411. When there is too much sewage and stains in the sewage tank 12, the detection mechanism sends a signal to the linear motor 411, which starts after receiving the signal, thereby connecting the sewage discharge channel 111 with the sewage discharge port 121. The suction channel 21 applies negative pressure to the sewage and stains to suck the sewage and stains into the base station 20. In addition, when the sewage and stains in the sewage tank 12 are completely discharged, the detection mechanism sends a stop signal to the linear motor 411, and the linear motor 411 retracts. The reset portion 50 drives the rotating shaft 31 to rotate in the opposite direction, thereby causing the cover plate 30 to close the sewage discharge channel 111 and the sewage discharge port 121.

[0062] To sum up, the present application provides a sewage outlet 121 at the bottom of the sewage tank 12, and a cover plate 30 is provided on the main body 11. The cover plate 30 switches between a first position and a second position through a rotating shaft 31. When the cover plate 30 is rotated to the first position, the cover plate 30 closes the sewage outlet 121. When the cover plate 30 is rotated to the second position, the cover plate 30 opens the sewage outlet 121 so that the stains or sewage in the sewage tank 12 can flow out from the sewage outlet 121. The structure of the present application avoids, to a certain extent, the need to disassemble the sewage tank 12 from the main body 11 when discharging stains or sewage in the sewage tank 12, which causes the cleaning device 10 to be inconvenient to use. In addition, the drive assembly 41 of the present application is connected to the rotating shaft 31 via a gear transmission portion 43, that is, the linear motor 411 can drive the transmission bracket 420 to reciprocate in a first direction, so that the rack 4201 on the transmission bracket 420 cooperates with the gear 423 connected to the rotating shaft 31, thereby driving the rotating shaft 31 to rotate. The transmission assembly 42 of the present application has a simple structure and strong stability. In addition, the transmission bracket 420 of the present application includes a first frame 421 and a second frame 422 that are detachably connected to each other. The first frame 421 is connected to the sewage tank 12, and the second frame 422 is disposed on the drive assembly 41. When the sewage tank 12 needs to be removed from the main body 11, since the first frame 421 and the second frame 422 are detachably disposed, interference between the sewage tank 12 and the drive assembly 42 will not occur during removal of the sewage tank 12. Finally, the present application also provides a cleaning system, which includes the above-mentioned cleaning equipment 10 and the base station 20. The sewage discharge channel 111 of the cleaning equipment 10 is connected to the suction channel 21 on the base station 20. The suction channel 21 can suck the stains and sewage in the sewage tank 12 into the base station 20 through the sewage discharge channel 111.

[0063] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0064] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0065] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
