Description

Technical Field

[0001] The utility model relates to the technical field of flush valves, and particularly relates to a pop-up flush valve. Background Art

[0002] A pop-up flush valve is a device used in toilets or other sanitary facilities. It can be quickly deployed when needed and folded up when not needed, saving space. This kind of flush valve is usually used in temporary occasions, such as construction sites, outdoor activities, disaster sites, etc., to provide convenient sanitary facilities. The foot-operated flush valve is usually installed near the ground. Only by stepping on the pedal can it flush water, which is convenient and hygienic. However, due to the large number of users, many people step on the pedal in the wrong direction, and the pedal is frequently stepped on in a non-normal direction, which is very easy to be damaged. For example, the connecting part between the pedal and the valve body is deformed or broken, resulting in phenomena such as no water flowing out or water leakage.

[0003] According to what is described in a foot-operated flush valve delay fixing device (authorization announcement number: CN216078479U) published on the patent network, this foot-operated flush valve delay fixing device includes "pipe clamps, support plates, L-shaped baffles", etc. to carry out the fixing work.

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] This foot-operated flush valve delay fixing device uses pipe clamps, support plates, L-shaped baffles, etc. to carry out the fixing work. When this device is in use, it uses the vertical surface of the L-shaped baffle to guide the pedal. Because the pedal is not in a vertical state during the movement process, but moves in an arc-shaped movement direction, the vertical movement mode will cause the pedal to be unable to move, affecting the use of the pedal, and it cannot play an auxiliary role when the pedal returns to its original position, and it cannot protect the periphery of the valve body, resulting in poor use effect. Therefore, this device needs to be improved. Content of the Utility Model
