The cleaning main unit and the handle bar are connected by a universal joint, and devices such as a clean water tank, a sewage tank, and a vacuum motor are installed on the handle bar. In actual use, it is found that when cleaning dead corners such as the bottom of a bed or a sofa, the handle bar needs to be flipped to a nearly horizontal state before the main body of the floor scrubber can be sent in and clean the dead corner. In this case, the sewage tank will change from the initial upright state to a flat state. In this state, the sewage in the sewage tank will form a surge and enter the vacuum motor through the air outlet, affecting the service life of the vacuum motor.

[0028] Example:

[0029] like Figures 1 to 8As shown, according to an overall technical concept of the present invention, a sewage tank with a surge backflow prevention structure is provided, including a tank body 1 and a tank cover 2, the tank cover 2 is sealed and connected to the top opening of the tank body 1, and a water inlet 221 and an air outlet 222 are provided on the tank cover 2, a vertically arranged partition 23 is provided on the bottom side of the tank cover 2, a horizontally arranged baffle 24 is formed on the bottom side of the partition 23, a surge prevention grid 242 is provided on the baffle 24, and a water-blocking cotton 4 and a surge prevention plate 232 are provided on the side of the partition 23; the surge prevention grid 242, the water-blocking cotton 4 and the surge prevention plate 232 are arranged in sequence from bottom to top to form a surge backflow prevention structure corresponding to the air outlet 222.

[0030] like Figures 1 to 8 As shown, in an exemplary embodiment of the present invention, the box cover 2 includes a cover body 21 and a cover plate 22, the cover body 21 is buckled on the top side of the cover plate 22, a HEPA frame mounting frame opening 211 is formed on the top side of the cover body 21, a sewage elbow pipe joint 212 is formed on the bottom side of the cover body 21, and a water inlet 221 and an air outlet 222 are both arranged on the cover plate 22; the water outlet end of the sewage elbow pipe joint 212 is sealedly connected to the water inlet 221, and the HEPA frame mounting frame opening 211 and the air outlet 222 are sealedly connected. By arranging a sewage pipe joint 212 on the bottom side of the cover body 21 to form a water inlet structure together with the water inlet 221 on the cover plate 22, when sewage enters the sewage tank, the water flows downward (that is, the water inlet direction is opposite to the suction direction). Compared with the prior art in which the water flows upward through the sewage inlet channel and then falls under the action of gravity (that is, the water inlet direction is consistent with the suction direction), the sewage in this solution is less likely to be sucked into the air outlet 222, thereby avoiding damage to the vacuum motor and facilitating flat operation; and the water inlet structure is arranged in the box cover 2, which is conducive to the box body 1 being formed into a container with a smooth inner surface, without sanitary dead corners, easy to clean, and will not hide dirt and grime, and can reduce odor.

[0031] In addition, a Hypa frame 3 is detachably installed in the Hypa frame installation frame opening 211, and a Hypa is detachably installed in the Hypa frame 3, which can filter the gas extracted from the sewage tank by the vacuum motor to avoid secondary pollution caused by the discharged gas.

[0032] like Figures 1 to 8 As shown, in an exemplary embodiment of the present invention, a partition 23 is formed on the bottom side of the cover plate 22, a water inlet 221 extends downward to communicate with one side of the partition 23 and form a water inlet cavity, and an air outlet 222 extends downward to communicate with the other side of the partition 23 and form an air outlet cavity. The partition 23 separates the water inlet 221 from the air outlet 222, which can prevent sewage from being sucked into the vacuum motor at the water inlet 221 by the airflow in the air outlet 222.

[0033] like Figures 1 to 8As shown, in an exemplary embodiment of the present invention, a solid-liquid separation grid 241 is further provided on the baffle 24, and the solid-liquid separation grid 241 is correspondingly arranged to the water outlet end of the water inlet cavity to separate solid waste and sewage.

[0034] like Figures 1 to 8 As shown, in an exemplary embodiment of the present invention, a downwardly inclined guide plate is provided at the water outlet of the water inlet channel, which can be used to guide the sewage to the solid-liquid separation grid 241 to separate the sewage and solid waste.

[0035] like Figures 1 to 8 As shown, in an exemplary embodiment of the present invention, the surge protection grid 242 is composed of a plurality of inclined grid plates 2421 arranged at equal intervals; two adjacent inclined grid plates 2421 are defined as the first grid plate and the second grid plate, and the air outlet side of the first grid plate and the air inlet side of the second grid plate are correspondingly arranged along the air flow direction (from bottom to top). This structure can prevent the sewage in the box body 1 from passing directly when a surge occurs, that is, when a surge occurs, the sewage hits the inclined grid plate 2421, and most of the sewage will flow back into the box body 1. In addition, by correspondingly arranging the air outlet side of the first grid plate and the air inlet side of the second grid plate along the air flow direction (from bottom to top), the above functions can be met while avoiding affecting the air flow rate.

[0036] like Figures 1 to 8 As shown, in an exemplary embodiment of the present invention, a water-blocking cotton mounting frame 231 is provided on the side of the partition 23, and the water-blocking cotton 4 is detachably mounted on the water-blocking cotton mounting frame 231; the anti-surge plate 232 is tilted toward the water-blocking cotton mounting frame 231. The water-blocking cotton 4 can be replaced regularly to avoid odor. During actual use, the sewage in the box 1 surges, most of the sewage is blocked by the anti-surge grid 242 and returns to the box 1, and a small part of the sewage is hit on the water-blocking cotton 4 through the anti-surge grid 242; the water-blocking cotton 4 is a porous structure and has a certain water absorption function, which can block this part of the sewage. Even if there is sewage that can pass through the water-blocking cotton 4, it will be "divided" into micro-granular water droplet structures by the water-blocking cotton 4; whether the handheld floor scrubber is in a vertical or horizontal use state, this part of the micro-granular water droplet structure will condense into large-grain water droplets on the bottom side of the anti-surge plate 232, and then flow to the partition 23 under the guidance of the anti-surge plate 232. Finally, when the handheld floor scrubber is stopped and upright, the large-grain water droplets flow back into the box 1 under the action of gravity.

[0037] It should be noted that when the handheld floor scrubber is in a vertical state, the large water droplets condensed on the bottom side of the anti-surge plate 232 are deposited at the angle between the anti-surge plate 232 and the partition 23 under the action of the airflow, and then flow back into the box 1 through the partition 23 under the action of gravity. When the handheld floor scrubber is in a flat state, the large water droplets condensed on the bottom side of the anti-surge plate 232 are deposited at the angle between the anti-surge plate 232 and the partition 23 under the combined action of airflow and gravity until the handheld floor scrubber is set upright, and this part of the sewage will flow back into the box 1 along the partition 23.

[0038] The anti-backflow structure can achieve multiple obstructions for sewage in a surge state to ensure that the sewage cannot flow back into the vacuum motor through the air outlet 222, thereby achieving the flat operation of the handheld floor scrubber.

[0039] like Figures 1 to 8 As shown, in an exemplary embodiment of the present invention, a downward sloping guide slope is provided on one side of the partition 23 close to the anti-surge grid 242, which is used to guide the sewage on the partition 23 to the anti-surge grid 242 and re-discharge it into the box body 1 through the anti-surge grid 242.

[0040] like Figures 1 to 8 As shown, in an exemplary embodiment of the present invention, the water inlet end of the sewage elbow joint 212 is formed on the side of the cover body 21; and a sewage pipe 5 is also included, which is arranged outside the box body 1 and is sealed and connected to the water inlet end of the sewage elbow joint 212. The sewage pipe 5 here can be designed as an integral structure or a detachable structure with the sewage pipe joint 212. By arranging the sewage pipe 5 outside the box body 1, the actual volume of the sewage tank can be increased, so that the amount of sewage that can be accommodated in the sewage tank is increased.

[0041] In addition, the present application also relates to a floor scrubber, which is composed of a floor scrubber body 100 and a hand-held rod 200 , and the sewage tank with the anti-surge backflow structure is detachably mounted on the hand-held rod 200 .

[0042] Therefore, the utility model has the following advantages:

[0043] The utility model provides a sewage tank and a floor scrubber with an anti-surge backflow structure, which prevents sewage from backflowing into a vacuum motor through the air outlet by arranging an anti-surge backflow structure on the bottom side of the tank cover corresponding to the air outlet. The anti-surge backflow structure is composed of stacked anti-surge grids, water-blocking cotton and anti-surge plates, which can achieve multiple blockages for sewage in a surge state to ensure that sewage cannot backflow into the vacuum motor through the air outlet 222, thereby achieving the handheld floor scrubber's flat operation.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
