[0030] Please refer to Figures 1 to 6 The utility model discloses a kind of automatic pollution discharge mechanisms for scrubber, including a scrubber body 1, a sewage tank 2 is provided in the scrubber body 1, further including a base 3 for accommodating scrubber body 1, and a pollution discharge assembly 4 is provided in the base 3, the pollution discharge assembly 4 includes a drive motor 41 being provided in the base 3, a drive gear 42 is provided on the output shaft of drive motor 41, a pollution discharge connecting pipe 43 is provided in the base 3 and one end is aligned with sewage tank 2 and the other end extends outward, a pollution discharge pipe 44 is connected to pollution discharge connecting pipe 43 and extends outward, a sewage switch top opening piece 45 is provided in pollution discharge connecting pipe 43 and upper end protrudes out of pollution discharge connecting pipe 43 and engages with drive gear 42, a pollution discharge port 21 is provided on the lower part of one side of pollution discharge connecting pipe 43, and a pollution discharge switch assembly 22 is provided to block the pollution discharge port 21.

[0031] When scrubber body 1 is placed into base 3, drive motor 41 is started to drive the drive gear 42 provided on the output shaft to rotate, so that the sewage switch top opening piece 45 engaged with the drive gear 42 moves towards the pollution discharge switch assembly 22 direction, and the pollution discharge switch assembly 22 is opened upwards, so that the sewage in the sewage tank 2 flows into the pollution discharge connecting pipe 43 from the pollution discharge port 21 at the lower part of the sewage tank 2 under the action of gravity, and then flows out of the outside in the pollution discharge pipe 44, to complete the whole pollution discharge process. The whole process is simple and convenient, and the sewage tank 2 in the scrubber body 1 can be discharged when the scrubber body 1 is placed into the base 3, without disassembling the sewage tank 2 for cleaning, the pollution discharge can be carried out while charging and other work, saving time and effort, without dirtying the user, effectively improving the user experience of using the scrubber.

[0032] Preferably, as Figure 5As shown, the pollution discharge assembly 4 further comprises a micro switch 46 arranged on the side wall of the pollution discharge connecting pipe 43. When the scrubber body 1 is placed into the base 3, the micro switch 46 is activated to control the driving motor 41 to start and begin the pollution discharge work. By arranging the micro switch 46 on the side wall of the pollution discharge connecting pipe 43, the micro switch 46 can be connected with the pollution discharge connecting pipe 43 and the base 3. The pollution discharge connecting pipe 43 can be pushed to be close to the scrubber by other mechanisms, so that the micro switch 46 can be moved to contact the base 3 to trigger the start, thereby making the start mode of the automatic pollution discharge mechanism more accurate and effectively improving the user experience of using the scrubber.

[0033] For the specific structure of the sewage switch top opener 45, as shown in Figures 5 to 6 As shown, the upper end of the sewage switch top opener 45 is formed with a driving rack 451, and the upper part of the driving rack 451 is formed with a plurality of teeth engaged with the driving gear 42. The lower part of the sewage switch top opener 45 is formed with a lifting part 452 extending towards the sewage tank 2.

[0034] For the specific structure of the pollution discharge switch assembly 22, as shown in Figures 2 to 3 and Figure 6 As shown, the pollution discharge switch assembly 22 comprises a switch fixing plate 221 arranged on the inner wall of the upper end of the sewage tank 2, an elastic member 222 fixed at one end of the switch fixing plate 221, and a pressing member 223 arranged at the other end of the elastic member 222. The pressing member 223 blocks and seals the pollution discharge port 21. The elastic member 222 is connected to the switch fixing plate 221, so that the pressing member 223 connected to the elastic member 222 is connected to the sewage tank 2, and is blocked on the pollution discharge port 21 under the elastic force of the elastic member 222, thereby sealing the pollution discharge port 21. Without external force, the sewage tank 2 is a sealed whole, preventing sewage from leaking out and ensuring the safe use of the scrubber.

[0035] Preferably, as shown in Figure 3 and Figure 6 The elastic member 222 is a spring, which has good durability, high elastic potential, and low price, effectively ensuring the service life of the automatic pollution discharge mechanism and reducing the production cost of the automatic pollution discharge mechanism.

[0036] When the drive motor 41 starts, the drive gear 42 on the output shaft of the drive motor 41 rotates accordingly. The teeth of the drive rack 451 meshing with the drive gear 42 drive the entire sewage switch top opening member 45 to move towards the sewage tank 2, so that the lifting part 452 aligns with the pressing member 223 and lifts the pressing member 223. The pressing member 223 squeezes the elastic member 222, compressing the elastic member 222, thereby allowing the sewage in the sewage tank 2 to flow out from the drain outlet 21. After the sewage is discharged, the drive motor 41 drives the drive gear 42 to rotate in the opposite direction, thereby driving the drive rack 451 meshing with the drive gear 42 to move the entire sewage switch top opening member 45 towards the drain pipe 44. The sewage switch top opening member 45 moves away from the pressing member 223, and the pressing member 223, under the elastic force of the elastic member 222, blocks the drain outlet 21, thereby sealing the drain outlet 21. The whole process is automatic and requires no manual intervention, saving time and effort, and effectively improving the user experience of using the floor scrubber.

[0037] Preferred, such as Figure 6 As shown, to further improve the efficiency of the sewage switch opening member 45 in lifting the pressing member 223, the lifting part 452 facing the sewage tank 2 has a first inclined lifting surface 4521 extending inclinedly downward from above the self-driving rack 451 towards the sewage tank 2. The lower part of the pressing member 223 facing the sewage pipe 44 has a second inclined lifting surface 2231 extending inclinedly from the upper outside towards the lower inside of the sewage tank 2 and matching the first inclined lifting surface 4521. When the sewage switch opening member... When the 45 moves toward the sewage tank 2, the first inclined lifting surface 4521 on the sewage switch opening member 45 first contacts the second inclined lifting surface 2231. Under the inclined guiding action of the first inclined lifting surface 4521 and the second inclined lifting surface 2231, the sewage switch opening member 45 can more easily and accurately open the pressing member 223, thereby allowing sewage to be discharged. This effectively improves the efficiency and accuracy of the water switch opening member in lifting the pressing member 223, and facilitates the cooperation between the various components.

[0038] Regarding the specific manner in which the pressing member 223 moves when it is lifted, as follows: Figure 3 As shown, a pressing groove 23 is formed on the lower inner wall of the sewage tank 2, which is directly opposite the sewage outlet 21 and allows the pressing member 223 to move. The pressing member 223 moves in the pressing groove 23 during the process of being pushed open by the sewage switch opening member 45, thereby satisfying the space required for the movement trajectory when it is pushed open, avoiding the pressing member 223 being blocked by external objects during the movement, and improving the efficiency of the movement of the pressing member 223.

[0039] Preferably, the pressing movable groove 23 is half a circular head column, and the lower end of the pressing piece 223 is a half-arc shape matching the pressing movable groove 23. By setting the pressing movable groove 23 as a half a circular head column, the tail end of the circular head shape can effectively limit the stroke of the pressing piece 223, prevent the pressing piece 223 from being pressed too much by the lifting part 452, and by setting the lower end of the pressing piece 223 as a half-arc shape matching the pressing movable groove 23, the pressing piece 223 can only interact within the pressing movable groove 23, preventing the pressing piece 223 from sliding left and right to cause the lifting part 452 to be stuck in other structures and unable to be pushed out, and other problems. And the half a circular head column is in an inclined state as a whole, so that the sewage in the sewage tank 2 can flow out more easily.

[0040] Preferably, in order to improve the speed of sewage flowing out of the sewage tank 2, a water pump can be provided on the sewage tank 2 or the sewage connection pipe 43 or the sewage pipe 44, which can pump the sewage out of the sewage tank 2, thereby improving the speed of sewage flowing out of the sewage tank 2.

[0041] For the specific way in which the sewage switch lifting part 45 moves on the sewage connection pipe 43, as shown in Figure 5 The sewage connection pipe 43 is formed with a driving moving groove 431 for the driving rack 451 to move, and the driving rack 451 moves in the driving moving groove 431 under the drive of the driving gear 42, thereby driving the entire sewage switch lifting part 45 to move on the sewage connection pipe 43, and the sewage switch lifting part 45 is limited by the forward and backward stroke of the driving moving groove 431, thereby effectively preventing the lifting part 452 from lifting the pressing piece 223 too much and causing the pressing piece 223 to be unable to reset, and other problems. The driving moving groove 431 is formed with driving limiting blocks 432 extending upward on both sides thereof and limiting the left and right positions of the driving rack 451, thereby limiting the left and right strokes of the driving rack 451 and preventing the driving rack 451 from driving the lifting part 452 to move left and right, which causes the lifting part 452 to be unable to normally lift the pressing piece 223. One set of driving limiting blocks 432 near the driving motor 41 further extends upward a motor fixing plate 433 for mounting the driving motor 41, and the driving motor 41 is mounted on the motor fixing plate 433, thereby achieving stable driving of the driving motor 41. The output shaft of the driving motor 41 penetrates the motor fixing plate 433, and the driving gear 42 is mounted on the other end of the output shaft penetrating out of the motor fixing plate 433, thereby engaging with the driving rack 451.

[0042] Preferably, the sewage switch lifting part 45 is further provided with a limiting block limiting the lifting part 452, thereby further preventing the lifting part 452 from moving left and right in the sewage connection pipe 43 and causing the pressing piece 223 to be unable to be accurately lifted.

[0043] Preferably, the sewage tank 2 is detachable at its upper end, and the whole can be detached from the scrubber body 1, so that the automatic sewage and manual cleaning can be performed at the same time, and the user can choose the two ways, thereby further improving the practicability of the scrubber.

[0044] It should be noted that the automatic sewage mechanism for the scrubber disclosed in the utility model is improved in the specific structure, and the specific control mode is not the innovation point of the utility model. The motor, spring, sewage pipe and other components involved in the utility model can be general standard components or components known by those skilled in the art, and the structure, principle and control mode are known by those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0045] The above is only a preferred embodiment of the utility model, and does not limit the technical range of the utility model in any way, so other structures obtained by using the same or similar technical features as the above embodiments of the utility model are within the protection scope of the utility model.
