Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[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, and a sewage outlet 121 is provided at the bottom of the sewage tank 12. The cover plate 30 is rotatably provided on the main body 11 via a rotating shaft 31, and the cover plate 30 has a first position for rotating around the rotating shaft 31 to close the sewage outlet 121 and a second position for opening the sewage outlet 121. A driving mechanism is provided on the main body 11, and the driving mechanism is used to drive the rotating shaft 31 to rotate so that the cover plate 30 switches between the first position and the second position.

[0040] Specifically, the existing cleaning equipment 10, such as a floor scrubber, is provided with a sewage tank 12, which 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, it is usually necessary to remove the sewage tank 12 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 a sewage outlet 121 is provided at the bottom of the sewage tank 12, and a cover plate 30 and a rotating shaft 31 are provided on the main body, the cover plate 30 is usually in the first position to close the sewage outlet 121. When it is necessary to discharge the dirt and sewage in the sewage tank 12, the cover plate 30 only needs to be driven by the rotating shaft 31 to rotate from the first position to the second position, so that the cover plate 30 opens the sewage outlet 121, and the sewage or stains will flow out under the action of gravity. In other words, when it is necessary to discharge the sewage or stains in the sewage tank 12, there is no need to disassemble the sewage tank 12 from the main body 11. It is only necessary to connect the sewage outlet 121 to the external sewage pipe to discharge the dirt and sewage in the sewage tank 12, thereby improving the convenience of sewage discharge of 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 disposed 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 shaft 31 is rotatably connected to the main body 11 , and the shaft 31 passes through the cover plate 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 through the gear transmission part 43, that is, after the motor is driven, the gear transmission part 43 rotates, and the rotating shaft 31 is connected to the gear transmission part 43. The rotation of the gear transmission part 43 drives the rotating shaft 31 to rotate, so that the cover plate 30 switches between the first position and the second position. In this embodiment, since the gear transmission part 43 is directly connected to the rotating shaft 31, the torque received by the gear transmission part 43 can be directly transmitted to the rotating shaft 31. Compared with other transmission methods, the transmission method using the gear transmission part 43 can improve the 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 part 43 does not need to apply excessive torque to the rotating shaft 31 when the cover plate 30 switches between the first position and the second position, the motor in this embodiment adopts a linear motor 411, which can accurately move a small distance, thereby driving the gear transmission part 43 to rotate a small angle, and finally enables the cover plate 30 to move from the first position to the second position, and the cover plate 30 will not be 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, the torque applied by the motor to the rotating shaft 31 is too large, which may cause the cover plate 30 to be damaged by excessive force.

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

[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 assembly 41 and the rotating shaft 31. The transmission bracket 420 is driven by the driving assembly 41 to move in a first direction (as shown in the attached figure). Fig.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 meshed with the gear 423, the gear 423 rotates under the drive of the rack 4201. When the gear 423 rotates, it drives the rotating shaft 31 to rotate, and finally the cover plate 30 rotates.

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

[0051] As attached Figure 7 As shown, a mounting groove 4202 is provided on one side of the transmission bracket 420 close to the cover plate 30, a gear 423 is embedded in the mounting groove 4202, a rack 4201 is provided on the top wall of the mounting groove 4202, and a linear motor 411 drives the transmission bracket 420 to reciprocate along a first direction, so that the rack 4201 moves along 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. The mounting groove 4202 for mounting the gear 423 provided on the transmission bracket 420 can improve the space utilization rate of the cleaning device 10 to a certain extent. In a preferred embodiment, the gear 423 is a half wheel, and the volume and manufacturing cost of the half wheel are relatively low, which can improve the space utilization rate 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 the present embodiment, the sewage tank 12 is detachably connected to the main body 11, so as to facilitate the maintenance of the sewage tank 12. Specifically, the transmission bracket 420 in the present embodiment includes a first frame 421 and a second frame 422 that are detachably connected to each other. The first frame 421 is arranged in the avoidance groove 61 of the fixed 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, when it is necessary to remove the sewage tank 12 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 be removed 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 , and the at least one second limiting protrusion 4221 is clamped between two adjacent first limiting protrusions 4211 .

[0055] As attached Fig. 9 As shown, the first limiting protrusion 4211 provided on the first frame 421 protrudes in the direction close to the linear motor 411, and the second limiting protrusion 4221 on the second frame 422 protrudes in the direction close to the fixing seat 60. In this embodiment, one second limiting protrusion 4221 is clamped between the two first limiting protrusions 4211. When the linear motor 411 drives the second frame 422 to reciprocate along the first direction, the second limiting protrusion 4221 applies an external force to the first limiting protrusion 4211, so that the first frame 421 moves along the same direction as the second frame 422, thereby making the rack 4201 on the first frame 421 cooperate with the gear 423, thereby driving the rotating shaft 31 to rotate. In addition, when it is necessary to disassemble the sewage tank 12 from the main body 11, the second limiting protrusion 4221 is taken out from between the two adjacent first limiting protrusions 4211, so as to prevent the sewage tank 12 from interfering with the first frame 421 when disassembling the sewage tank 12.

[0056] Furthermore, the driving mechanism further includes a reset portion 50 , which is disposed between the rotating shaft 31 and the main body 11 , and is used 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 seat 60, and one end of the rotating shaft 31 is rotatably fixed on 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 which abuts against the support protrusion 62, and the other end of which abuts against the fixing seat 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 the external force, and when the linear motor 411 removes the external force, the torsion spring applies a force to the rotating shaft 31, so that the rotating shaft 31 rotates in the opposite direction, thereby driving the cover plate 30 to move from the second position to the first position to close the sewage outlet 121.

[0058] Furthermore, the main body 11 is provided with a drainage channel 111 corresponding to the drainage port 121. Specifically, when the cover plate 30 moves to the second position, the drainage port 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 moves to the first position, the cover plate 30 closes the drainage port 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 opened on the fixing seat 60, and the cover plate 30 is arranged between the drainage channel 111 and the drainage port 121. When the cover plate 30 moves 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 port 121; when the cover plate 30 is located in the first position, the cover plate 30 closes the drainage port 121 and the drainage channel 111 at the same time.

[0059] On the other hand, the present application also provides a cleaning system, which includes the above-mentioned cleaning device 10 , and the cleaning system also includes a base station 20 , and 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 discharge the dirt and sewage in the sewage tank 12, the cleaning device 10 only needs to be placed on the base station 20, so that the sewage discharge channel 111 is connected with the suction channel 21, and then the linear motor 411 is started to move the cover plate 30 from the first position to the second position, the sewage discharge port 121 is opened, and the dirt and sewage enter the suction channel 21 from the sewage discharge channel 111. In this embodiment, there is a certain negative pressure in the suction channel 21, and the negative pressure can have a certain adsorption effect on the dirt and sewage in the sewage tank 12, so that the dirt and sewage can enter the base station 20.

[0061] In addition, the base station 20 is also provided with a detection mechanism (not shown in the figure), which is used to detect whether the cleaning device 10 has returned to the base station 20, and the detection mechanism can also detect whether it is necessary to discharge the sewage and stains in the sewage tank 12 of the cleaning device 10, and the detection mechanism is electrically connected or communicatively connected with 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, and the linear motor 411 starts after receiving the signal, so that the sewage discharge channel 111 is connected with the sewage discharge port 121, and 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 discharged, the detection mechanism sends a stop signal to the linear motor 411, the linear motor 411 retracts, and the reset part 50 drives the rotating shaft 31 to rotate in the opposite direction, so that the cover plate 30 closes the sewage discharge channel 111 and the sewage discharge port 121.

[0062] In summary, the present application sets a sewage outlet 121 at the bottom of the sewage tank 12, and a cover plate 30 is set 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, to a certain extent, avoids the problem of inconvenience in using the cleaning device 10 due to the need to disassemble the sewage tank 12 from the main body 11 when discharging stains or sewage in the sewage tank 12. In addition, the drive assembly 41 in the present application is connected to the rotating shaft 31 through the gear transmission part 43, that is, the linear motor 411 can drive the transmission bracket 420 to reciprocate in the 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 in 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 arranged on the drive assembly 41. When the sewage tank 12 needs to be disassembled from the main body 11, since the first frame 421 and the second frame 422 are detachably arranged, when the sewage tank 12 is disassembled, it will not cause interference between the sewage tank 12 and the drive assembly 42. 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 here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure. For example, if the device in the accompanying 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 only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
