[0010] Furthermore, the buckle assembly includes a slot located in the middle of the body and a buckle located inside the connector, the top of the buckle is arranged inside the slot, and a spring is provided at the middle 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 fuselage, a connecting port is opened on the bottom side of the sewage tank body, and the connecting port is arranged on 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 utility model has the following beneficial effects:

[0016] In the utility model, when sewage flows into the L-shaped tube through the connecting tube and then flows into the interior of the sewage tank body, the sewage is stored inside the sewage tank body. When the sewage tank body is rotated to a horizontal position, the liquid level of the sewage inside the sewage tank body will be lower than the top opening of the L-shaped tube, so that the sewage will not flow out along the L-shaped tube, thereby causing the backflow phenomenon. By ensuring that the sewage can only flow into the sewage tank and will not flow back into 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment of a sewage tank structure with backwater prevention, comprising:

[0024] Among them, there are multiple sealing strips 11 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 the L-shaped tube 9, and the top outer wall of the sewage tank body 7 is fixedly connected to the handle 6;

[0025] Specifically, the multiple sealing strips 11 provided 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, thereby preventing 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 tube 9 for storage. The handle 6 provided 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 the card slot 2 is located at the middle end of the fuselage 1 and the card buckle 4 is located inside the connector 5, the top end of the card buckle 4 is set inside the card slot 2, the middle end of the connector 5 is provided with a spring 12, 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, the connecting pipe 3 is located at the bottom end of the fuselage 1, and the bottom side of the sewage tank body 7 is provided with a connecting port 10, and the connecting port 10 is set on the top side of the connecting pipe 3, and the top end of the L-shaped pipe 9 is set on the side of the baffle 8 facing the fuselage 1, so as to transport sewage to the interior of the sewage tank body 7;

[0027] Specifically, the buckle 4 can be stuck in the inside of the card slot 2, and the connecting head 5 and the sewage tank body 7 can be installed on the fuselage 1. At the same time, when the connecting head 5 and the sewage tank body 7 need to be removed from the fuselage 1, the handle 6 can be buckled and the buckle 4 can be pressed down to compress the spring 12, so that the top of the buckle 4 is disengaged from the inside of the card slot 2, so that the connecting head 5 and the sewage tank body 7 can be 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 tube 9 is connected to the connecting port 10. , the sewage can be transported from the inside of the body 1 to the inside of the sewage tank body 7. At the same time, 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 connecting port 10 is in contact with the connecting pipe 3, and then the sewage is transported to the interior of the sewage tank body 7 through the L-shaped tube 9. When the sewage flows into the interior of the sewage tank body 7, the sewage will not flow out from the bottom end 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 tube 9 is higher than the liquid level, so the sewage will not flow back along the L-shaped tube 9. When the sewage inside the sewage tank body 7 needs to be dumped, the handle 6 can be buckled and the buckle 4 can be pressed down to compress the spring 12, so that the top of the buckle 4 and the card slot 2 are disengaged, and the connector 5 and the sewage tank body 7 are removed from the interior of the fuselage 1. After the connector 5 is pulled out from the top of the sewage tank body 7, 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, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
