Description
Technical Field
[0001] The utility model relates to the field of cleaning equipment, in particular to a sewage tank structure and a floor scrubber capable of preventing backflow. Background Art
[0002] At present, the structure of the portable floor scrubbers on the market is as follows: including a cleaning main body and a handle bar, the cleaning main body and the handle bar are connected by a universal joint, and a clean water tank, a sewage tank, a vacuum pump and other devices are installed on the handle bar. The structure of the sewage tank is mostly as follows: including a box body, a box opening is formed on the box body, a water inlet pipe part and an air extraction pipe part are formed on the box body, the air extraction pipe part extends into the box body, and the air extraction pipe part is between the water inlet pipe part and the box opening; when in use, the sewage tank is installed on the handle bar of the floor scrubber, and a vacuum pump is installed below the sewage tank. The water inlet pipe part of the sewage tank is connected to the sewage suction hole set in the cleaning main body through a water pipe, and the air extraction pipe part of the sewage tank is connected to the air extraction port of the vacuum pump through an air channel, and the air channel is a cavity formed in the handle bar. The function of the sewage tank is to collect the sewage generated by the cleaning host during the cleaning process. The sewage tank uses a vacuum pump to extract the air in the box from the exhaust pipe part of the box body, so that negative pressure is formed in the sewage tank, thereby sucking away the sewage generated by the cleaning host during the cleaning process.
[0003] In actual use, there are often cleaning dead corners such as under the bed, which require the user to operate the cleaning equipment while lying down. In this state of use, the sewage in the sewage tank will flow back into the vacuum motor, thereby affecting the service life of the vacuum motor.
[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to design a sewage tank structure and a floor scrubber that prevents backflow to solve the above problems. Utility Model Content
[0005] In order to overcome the above-mentioned deficiencies in the prior art, the utility model aims to provide a sewage tank structure and a floor scrubber that prevents backflow.
[0006] In order to achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is: a sewage tank structure that prevents backflow, including a box body, wherein at least one partition extending toward the opposite side is provided on the side wall of the box body close to the user side, and the bottom of the box body is provided with a water inlet, and the water inlet extends inwardly to form a sewage pipe that passes through the partition; the top of the box body is provided with an exhaust port away from the user side, and the exhaust port extends inwardly to form an exhaust pipe.
[0007] The preferred technical solution is: an opening structure is formed between the end of the partition and the inner wall of the box body, a floating plate corresponding to the opening structure is hinged on the inner wall of the box body, the side of the floating plate away from the hinged side extends to the bottom side of the partition, and a float is provided at the bottom of the side of the floating plate away from the hinged side.
[0008] The preferred technical solution is: a cover body is provided on the top of the box body, and the cover body and the inner wall of the box body on the side away from the user's use side constitute a water retaining structure that partially covers the exhaust pipe.
[0009] A floor scrubber comprises the above-mentioned sewage tank structure.

[0011] The utility model provides a sewage tank structure and a floor scrubber for preventing backflow. At least one partition extending toward the opposite side is provided on the side wall of the tank body close to the user's use side, so that when the sewage tank is in a flat use state, the partition can form a container with part of the tank body, thereby preventing the sewage from completely flowing to the position of the exhaust pipe on the top of the tank body. This structure can avoid the problem of sewage backflow. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Example:
[0017] like Figure 1 As shown, according to an overall technical concept of the utility model, a sewage tank structure for preventing backflow is provided, including a box body 1, and at least one partition 11 extending toward the opposite side is provided on the side wall of the box body 1 close to the user side. A water inlet is provided at the bottom of the box body 1, and the water inlet extends inwardly to form a sewage pipe 12 that penetrates the partition 11; an air suction port is provided at the top of the box body 1 away from the user side, and the air suction port extends inwardly to form an air suction pipe 13.
[0018] like Figure 1 As shown, in an exemplary embodiment of the utility model, an opening structure is formed between the end of the partition 11 and the inner wall of the box body 1, and a floating plate 2 corresponding to the opening structure is hinged on the inner wall of the box body 1, and the side of the floating plate 2 away from the hinged side extends to the bottom side of the partition 11, and a float 3 is provided at the bottom of the side of the floating plate 2 away from the hinged side.
[0019] like Figure 1 As shown, in an exemplary embodiment of the utility model, a cover body 14 is provided on the top of the box body 1, and the cover body 14 and the inner wall of the box body 1 on the side away from the user's use side constitute a water retaining structure that partially covers the exhaust pipe 13 to prevent sewage from being sucked into the vacuum motor and affecting the service life of the vacuum motor.
[0020] A floor scrubber comprises the above-mentioned sewage tank structure.
[0021] In the upright state of use, the floating plate 2 droops under the action of its own weight, and the opening structure opens to allow sewage to flow to the lower side of the partition 11; as the amount of sewage injected increases, the floating plate 2 is lifted under the buoyancy of the floating ball 3;
[0022] When lying flat for use, the float 2 blocks the opening structure under the action of its own weight, the buoyancy of the float 3 and the surge, thereby preventing the sewage on the lower side of the partition from flowing into one side of the exhaust pipe 13 to form a surge; the sewage in this state is sucked to the upper side of the partition 11, and the amount of sewage is small, making it difficult to form a large surge and be sucked into the exhaust pipe 13; after being erected, the float 2 opens the opening structure under the action of its own weight, and the sewage on the upper side of the partition 11 will automatically flow to the lower side of the partition 11.
[0023] Therefore, the utility model has the following advantages:
[0024] The utility model provides a sewage tank structure and a floor scrubber for preventing backflow. At least one partition extending toward the opposite side is provided on the side wall of the tank body close to the user's use side, so that when the sewage tank is in a flat use state, the partition can form a container with part of the tank body, thereby preventing the sewage from completely flowing to the position of the exhaust pipe on the top of the tank body. This structure can avoid the problem of sewage backflow.
[0025] 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.
