[0002] The sewage tank is a container for collecting sewage and storing dirt, and the sewage tank of a floor scrubber is an important component inside the floor scrubber. Its main function is to collect and store dirty water and dirt sucked up during the floor cleaning process.

[0003] However, when the sewage tank is storing sewage, sewage may flow back to other parts of the floor scrubber, which may cause damage to the motor inside the floor scrubber, result in poor cleaning effect on the floor, and cause odor on the floor after cleaning, which may worsen the user experience. In response to this technical problem, the present application proposes a sewage tank structure with anti-backflow protection. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a sewage tank structure with anti-backflow is proposed. When sewage flows into the L-shaped pipe through the connecting pipe and then flows into the interior of the sewage tank body, the sewage is stored in the interior of the sewage tank body. When the sewage tank body is rotated to a horizontal position, the internal liquid level of the sewage in the sewage tank body will be lower than the top opening of the L-shaped pipe, so that the sewage will not flow out along the L-shaped pipe, resulting in the phenomenon of backflow.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A sewage tank structure with backwater prevention, comprising:

[0007] A connector, the bottom end of which is connected to a sewage tank body through a sealing assembly to ensure the sealing of the sewage tank body opening, and an L-shaped pipe is fixedly connected to the inner wall of the sewage tank body;

[0008] The connecting head is connected to the body through a snap assembly, and the bottom end of the sewage tank body is connected to the body through a connecting piece, so as to transport sewage to the interior of the sewage tank body.

[0009] Furthermore, the sealing assembly includes a plurality of sealing strips located at the bottom end of the connector, and a baffle is fixedly connected to the bottom side of the connector.

[0010] Furthermore, the buckle assembly includes a slot located at the middle end of the body and a buckle located inside the connector, the top end of the buckle is arranged inside the slot, and a spring is arranged at the middle end of the connector.

[0011] Furthermore, one end of the spring is connected to the bottom end of the buckle, and the other end of the spring is connected to the middle end of the connector.

[0012] Furthermore, the connecting member includes a connecting pipe located at the bottom end of the body, a connecting port is provided at the bottom side of the sewage tank body, and the connecting port is arranged at the top side of the connecting pipe.

[0013] Furthermore, a handle is fixedly connected to the top outer wall of the sewage tank body.

[0014] Furthermore, the top end of the L-shaped tube is arranged on a side of the baffle facing the fuselage.

[0015] The present invention has the following beneficial effects:

[0016] In the present invention, when sewage flows into the L-shaped pipe through the connecting pipe and then flows into the interior of the sewage tank body, the sewage is stored in the interior of the sewage tank body. When the sewage tank body is rotated to be horizontal, the internal liquid level of the sewage in the sewage tank body will be lower than the top opening of the L-shaped pipe, so that the sewage will not flow out along the L-shaped pipe, thereby causing the phenomenon of backflow. By ensuring that the sewage can only flow into the sewage tank and will not flow back to other parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 3 , an embodiment provided by the present invention: a sewage tank structure with anti-backwater, comprising:

[0024] Among them, there are multiple sealing strips 11 located at the bottom end of the connector 5, and a baffle 8 is fixedly connected to the bottom side of the connector 5 to ensure the sealing of the opening of the sewage tank body 7. The inner wall of the sewage tank body 7 is fixedly connected to an L-shaped tube 9, and the top outer wall of the sewage tank body 7 is fixedly connected to a handle 6;

[0025] Specifically, the multiple sealing strips 11 arranged at the bottom end of the connecting head 5 can provide sufficient sealing when the sewage tank body 7 and the bottom end of the connecting head 5 are connected, so as to prevent sewage from flowing out from the connection between the sewage tank body 7 and the connecting head 5. At the same time, when the sewage tank body 7 and the connecting head 5 are installed, the sealing strip 11 is stuck at the connection between the sewage tank body 7 and the connecting head 5, so that the sewage tank body 7 can be further firmly installed on the connecting head 5. At the same time, the sewage inside the fuselage 1 can flow into the interior of the sewage tank body 7 through the L-shaped pipe 9 for storage. The handle 6 arranged on the outer wall of the sewage tank body 7 can ensure that the staff can hold the sewage tank body 7 to dump the sewage and buckle the handle 6 to facilitate pressing the buckle 4 to remove the connecting head 5 and the sewage tank body 7 from the fuselage 1.

[0026] Reference Figure 1-Figure 3 , wherein a card slot 2 is located at the middle end of the fuselage 1 and a card buckle 4 is located inside the connector 5, the top end of the card buckle 4 is arranged inside the card slot 2, a spring 12 is arranged at the middle end of the connector 5, one end of the spring 12 is connected to the bottom end of the card buckle 4, and the other end of the spring 12 is connected to the middle end of the connector 5, a connecting pipe 3 is located at the bottom end of the fuselage 1, a connecting port 10 is opened at the bottom side of the sewage tank body 7, and the connecting port 10 is arranged on the top side of the connecting pipe 3, and the top end of the L-shaped pipe 9 is arranged on the side of the baffle 8 facing the fuselage 1, so as to transport sewage to the inside of the sewage tank body 7;

[0027] Specifically, the buckle 4 can be stuck in the inside of the slot 2, and the connector 5 and the sewage tank body 7 are installed on the fuselage 1. At the same time, when the connector 5 and the sewage tank body 7 need to be removed from the fuselage 1, the handle 6 can be buckled, and then the buckle 4 is pressed down to compress the spring 12, so that the top of the buckle 4 is separated from the inside of the slot 2, so that the connector 5 and the sewage tank body 7 are removed from the fuselage 1. At the same time, when the sewage tank body 7 is installed on the fuselage 1, the connecting port 10 is set at the top of the connecting pipe 3, and the bottom end of the L-shaped pipe 9 is connected to the connecting port 10. , the sewage can be transported from the inside of the fuselage 1 to the inside of the sewage tank body 7. At the same time, the shape of the L-shaped tube 9 is L-shaped. When the sewage tank body 7 rotates and the sewage tank body 7 remains horizontal, the liquid level inside the sewage tank body 7 will not be higher than the opening at the top of the L-shaped tube 9. Therefore, when the sewage tank body 7 is in a vertical state or a horizontal state, the sewage inside the sewage tank body 7 will not flow out from the opening of the L-shaped tube 9, resulting in the backflow of sewage. The anti-backflow effect of the sewage tank body 7 can be achieved by ensuring that the sewage can only flow into the sewage tank and will not flow back to other parts.

[0028] Working principle: the connection port 10 is in contact with the connection pipe 3, and then the sewage is transported to the interior of the sewage tank body 7 through the L-shaped pipe 9. When the sewage flows into the interior of the sewage tank body 7, the sewage will not flow out from the bottom of the sewage tank body 7. When the sewage tank body 7 is rotated to a horizontal state, the opening at the top of the L-shaped pipe 9 is higher than the height of the liquid surface, so the sewage will not flow back along the L-shaped pipe 9. When it is necessary to dump the sewage inside the sewage tank body 7, the handle 6 can be buckled, and then the buckle 4 can be pressed down to compress the spring 12, and the top of the buckle 4 and the card slot 2 can be disengaged, so as to realize the removal of the connector 5 and the sewage tank body 7 from the interior of the fuselage 1, and then the connector 5 can be pulled out from the top of the sewage tank body 7, and the sewage inside the sewage tank body 7 can be dumped out.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
