Example 1

Referring to fig. 1 and 2, the present embodiment provides a waste water tank 20, which includes a tank body 22 and a cover (not shown) detachably connected to the tank body 22, wherein the tank body 22 and the cover enclose an accommodation space 24. The accommodating space 24 can be used for accommodating sewage. Normally, the housing 22 is provided with a sewage inlet through which sewage enters the housing space 24. The cover body is provided with an air outlet, a suction motor is arranged at the downstream of the air outlet, the suction motor sucks air in the accommodating space 24 through the air outlet, negative pressure is formed in the accommodating space 24, and therefore sewage can be sucked into the accommodating space 24 from the sewage inlet.

When the sewage tank 20 needs to be cleaned, a user usually opens the cover to pour out the sewage. However, if there are stains adhered to the inner wall of the body of the sewage tank 20, the stains are difficult to flow out with the sewage, and it is inconvenient for a user to clean the stains with the aid of tools. Moreover, if the stains are not thoroughly cleaned, peculiar smell is easily generated after a period of time, and user experience is affected.

Referring to fig. 2 to 4, in order to better clean the stains, the wastewater tank 20 of the present invention further includes a stirring assembly 26, wherein the stirring assembly 26 stirs the wastewater, and the stirred wastewater can wash away the stains adhered to the inner wall of the tank 22, so as to achieve the purpose of self-cleaning, and the present invention is more convenient to use and can improve user experience.

The agitation assembly 26 includes an agitation head 28 positioned in the receiving space 24, and a connecting member 30 connected to the agitation head 28, the connecting member 30 driving the agitation head 28 to move. Thus, the connector 30 drives the stirring head 28 to move, so that the sewage in the accommodating space 24 is stirred, and the sewage tank 20 is self-cleaned.

The connector 30 rotates to rotate the agitator head 28. The rotation is the most direct driven mode, and particularly under the condition of being driven by a motor, the driving can be realized without additional motion conversion, and the structure is simpler and more reliable; and when the stirring head 28 rotates, the sewage can be stirred to form a rotating vortex (similar to a tornado shape), and the cleaning force generated by the rotating vortex is extremely large, so that the dirt adhered to the inner wall of the box body 22 can be cleaned to the maximum extent.

The agitator head 28 includes at least two agitator blades 32, the at least two agitator blades 32 being circumferentially spaced apart. The stirring blades 32 arranged at the circumferential gaps can stir sewage more uniformly in the circumferential direction, so that the sewage in the box body 22 is stressed more uniformly, the sewage rotates more smoothly, and stronger cleaning force is formed.

Referring to fig. 4 and 5, the agitating head 28 includes at least two agitating blades 32, and distal ends 34 of adjacent two agitating blades 32 are spaced apart in the extending direction of the connecting member 30. The coupling member 30 is a shaft-like member extending lengthwise, and the tips 34 of the agitating blades 32 are spaced in the extending direction of the coupling member 30, that is, the tips 34 of the agitating blades 32 are spaced in the height direction, so that sewage of different depths can be agitated, the movement amplitude of the sewage is made larger, and a stronger cleaning force is formed.

In particular, the agitation head 28 includes four agitating blades 32, and the four agitating blades 32 are arranged at even intervals in the circumferential direction. Specifically, two opposite blades 32 are uniformly arranged at intervals of 180 degrees in the circumferential direction, and the tips 34 of the two opposite blades 32 are arranged at the same height in the extending direction of the connecting piece 30; two adjacent blades 32 are arranged at intervals of 90 degrees in the circumferential direction, and tips 34 of the two adjacent blades 32 are arranged at intervals in the extending direction of the connecting member 30. The structure is relatively simple, but sewage can be stirred to the maximum extent, and the motion amplitude of the sewage is improved to the maximum extent.

Referring to fig. 5, the connecting member 30 passes through the bottom wall 36 of the box 22, and the connecting member 30 is partially located in the accommodating space 24 and partially located outside the accommodating space 24. When the connecting member 30 penetrates through the bottom wall 36 of the tank body 22, the stirring head 28 connected with the portion of the connecting member 30 located in the accommodating space 24 is relatively close to the bottom wall 36 of the tank body 22, and it is conceivable that solid dirt in the sewage sinks to the bottom wall 36 of the tank body 22 under the action of gravity after the operation of the sewage tank 20 is stopped, so that the dirt on the bottom wall 36 of the tank body 22 is relatively difficult to clean, and when the stirring head 28 is close to the bottom wall 36 of the tank body 22, the stirring head 28 can more directly stir the dirt sinking to the bottom wall 36 of the tank body 22, thereby improving the cleaning efficiency of the sewage tank 20. The portion of the connector 30 outside the receiving space 24 is connectable to a driving source, such as a motor 46, so that the connector 30 drives the stirring head 28 to rotate under the driving of the driving source, thereby cleaning. The motor 46 is housed in the motor case 44. The structural design is very reasonable.

The connecting member 30 passes through the bottom wall 36 of the box body 22, so that the bottom wall 36 of the box body 22 is inevitably provided with a through hole through which the connecting member 30 passes, and the box body 22 can contain sewage, therefore, the waterproof work must be done. In order to prevent sewage from seeping out of the through hole, the bottom wall 36 of the box body 22 is recessed to form a groove, the sewage tank 20 further comprises a waterproof member 38 arranged in the groove, and the connecting member 30 extends into the accommodating space 24 through the waterproof member 38. Thus, the waterproof member 38 can prevent the sewage from seeping out of the through hole; and the waterproof piece 38 is arranged in a groove formed by the concave of the bottom wall 36 of the box body 22, and the lower surface of the waterproof piece 38 is higher than the lowest surface of the box body 22 or is approximately flush with the lowest surface of the box body 22, so that the structure is more regular.

In this embodiment, the connecting member 30 is a transmission shaft, and the waterproof member 38 is a waterproof bearing. The waterproof bearing can not only prevent sewage from seeping out of the through hole, but also support the connecting piece 30, so that the transmission of the connecting piece 30 is more reliable.

The flashing 38 is provided with an axial stop assembly on the side thereof remote from the agitator head 28 to limit the axial position of the agitator head 28 to prevent the agitator blades 32 from scraping against the bottom wall 36 of the housing 22 as the agitator head 28 moves downwardly.

In this embodiment, the axial limiting assembly includes a rubber gasket 40 abutting against a side of the waterproof member 38 away from the stirring head 28, and a collar 42 abutting against a side of the rubber gasket 40 away from the stirring head 28, the connecting member 30 is provided with a circumferentially extending clamping groove corresponding to the collar 42, the collar 42 is partially clamped in the clamping groove, a side of the collar 42 away from the stirring head 28 abuts against other components, for example, a side of the collar 42 away from the stirring head 28 abuts against the motor housing 44. Thus, the motor housing 44 limits the axial position of the collar 42, while the coupler 30 is axially fixed with the collar 42, and the motor housing 44 limits the axial position of the coupler 30, and thus the agitator head 28.

Example 2

Referring to fig. 6, the present embodiment provides a floor washing machine 100, wherein the floor washing machine 100 comprises a spraying system, a cleaning system and a recovery system, and the recovery system comprises the waste water tank 20 of embodiment 1.

Thus, the spraying system sprays cleaning liquid to the surface to be cleaned, the cleaning system washes the surface to be cleaned with the liquid, and then the sewage recovery system recovers the sewage. Since the floor washing machine 100 includes the sewage tank 20 capable of self-cleaning according to embodiment 1, the floor washing machine 100 provided by this embodiment has a cleaner sewage tank 20, and is more convenient to use and better in user experience.

Referring to fig. 5 and 6, the scrubber 100 further includes a motor 46, and the connecting member 30 is connected to the motor 46 and driven by the motor 46 to rotate. Thus, the motor 46 drives the connection member 30, and the connection member 30 drives the agitation head 28 to rotate rapidly, thereby achieving efficient and rapid self-cleaning of the wastewater tank 20.

The scrubber 100 also includes a detection module and a control module in communication with the motor 46. The detection module detects a certain index, when the index reaches a threshold value, the control module starts the motor 46, and the motor 46 drives the stirring head 28 to rotate through the connecting piece 30, so that the self-cleaning and automatic operation of the sewage tank 20 are realized, and the operation is convenient and labor-saving.

In one embodiment, the sensing module senses the resting time of the wastewater tank 20, and when the resting time of the wastewater tank 20 exceeds a preset value, the control module activates the motor 46, and the motor 46 drives the stirring head 28 to move through the connection member 30. In the moving process of sewage, the stain is not easy to adhere to the inner wall of the sewage tank 20, after the sewage tank 20 is stood, the stain is easy to precipitate and adhere to the inner wall of the sewage tank 20, and after the standing time of the sewage tank 20 exceeds the preset value, the motor 46 is started to drive the stirring head 28 to move, so that the stain can be effectively prevented from precipitating and adhering to the inner wall of the sewage tank 20. Moreover, the sound of the agitator head 28 agitating the waste water also provides an indication to the user that the waste water can be dumped.

In another embodiment, the sensing module senses the water level of the wastewater tank 20, and when the water level of the wastewater tank 20 exceeds a preset value, the control module activates the motor 46, and the motor 46 drives the stirring head 28 to move through the connection member 30. When the water level of the wastewater tank 20 exceeds the predetermined value, more stains may be deposited and adhered to the inner wall of the wastewater tank 20, and the wastewater tank 20 is more difficult to clean. When the water level in the waste water tank 20 exceeds the predetermined value, the motor 46 is started to drive the stirring head 28 to move, so that the dirt can be effectively prevented from being deposited and adhered on the inner wall of the waste water tank 20. Moreover, the sound of the agitator head 28 agitating the waste water also provides an indication to the user that the waste water can be dumped.
