Closed foot-operated valve

Abstract

The closed foot-operated valve (the closed foot valve and the closed foot delay valve) is composed of a closed foot device and an existing foot-operated valve (the foot valve and the foot delay valve), and has the advantages of being safe to use, not prone to damage, convenient to maintain, attractive in appearance, suitable for a family kitchen or a toilet in a public place and easy to popularize and use. The foot-operated valve (a foot-operated valve and a foot-operated time-delay valve) can play roles in guaranteeing the sanitation of a toilet, saving water in the toilet and avoiding contact infection of the toilet.

Description

Technical Field

[0001] The present invention relates to a closed foot-controlled valve (or closed foot valve, or closed foot delay valve) used in kitchens or bathrooms to control water use of faucets, urinals, and squat toilets, save kitchen water, ensure bathroom hygiene, save bathroom water, and prevent contact infection in the bathroom. Background Art

[0002] At present, the known foot-controlled valve (or foot valve, or foot-operated delay valve) is characterized by an open structure in which the contact (valve stem), valve cover, and valve seat (body) are connected in parallel and do not contain each other. For example, in patent ZL201410772662.0, its contact (valve stem), valve cover, and valve seat (body) are connected in parallel and do not contain each other. Due to this structure, it has problems such as unsafe use, easy damage, inconvenient maintenance, and unsightly appearance. Therefore, it is difficult to popularize and use foot-controlled valves (foot valves, foot-operated delay valves) in family kitchens or public toilets, and it is difficult to play the role of foot-controlled valves in saving water in family kitchens or public toilets, ensuring hygiene, and preventing contact infection. In order to overcome the problems of unsafe use, easy damage, inconvenient maintenance, and unsightly appearance of existing foot-controlled valves (foot valves, foot-operated delay valves), which are not conducive to popularization and use, the present invention is proposed.

The (semi)enclosed foot-operated delay valve of the present invention is installed on the side of the foot-operated position when using a squat toilet or urinal; the water inlet (13) of the (semi)enclosed foot-operated valve ((semi)enclosed foot-operated valve) is connected to a water pipe; the water outlet (14) is connected to a water tank (or to a urinal or to a faucet); the drainage hole (12) is connected to a drainage pipe (or is closed, or the water outlet (14) is connected to a urinal or to a faucet); when the foot is stepped on the foot pedal (1) of the (semi)enclosed foot-operated valve of the present invention, the valve is opened to allow water to enter; when the foot leaves the foot pedal (1), the valve is closed to allow water to enter, and water is discharged from the drainage pipe, thereby achieving the working purpose of the present invention (for details of the working, see Patent ZL2013 1 0549327.X or Patent ZL201410772662.0,); The semi-enclosed foot-controlled valve is similar to the enclosed foot-controlled valve in that after the valve body is completely buried underground, maintenance is still convenient. The difference is that the valve stem (11) is not enclosed and there is still a risk of kicking. The internal and external structures of the present invention are not limited to the structures shown in the accompanying drawings. The internal and external structures of the present invention may vary due to different manufacturing processes or personal preferences, but the principle remains unchanged. .

[0004] The beneficial effect of the present invention is to overcome the problems of existing foot-controlled valves (foot valves, foot-operated delay valves) such as unsafe use, easy damage, inconvenient maintenance and unsightly appearance, which hinder the popularization and use of foot-controlled valves (foot valves, foot-operated delay valves) and make it difficult for foot-controlled valves (foot valves, foot-operated delay valves) to play a role in saving kitchen water or ensuring bathroom hygiene, saving bathroom water and preventing contact infection in the bathroom.
