Description

technical field

[0001] The invention relates to a drain valve for a toilet. Background technique

[0002] The drain valve used for toilets in the existing market adopts a direct pressing structure, because its main components are the valve stem and spring inside the drain valve body, but because of the need for reset, the spring has a relatively large spring reaction force , causing consumers to press with greater force. Moreover, the position for pressing the valve stem is placed on the water outlet end of the drain valve, resulting in easy water leakage and inconvenient pressing angles. Furthermore, the sealing part at the water outlet adopts soft materials: such as rubber, which is easy to age after a long time, resulting in sealing failure and water leakage, which greatly affects the service life of the drain valve. Contents of the invention

[0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a drain va...
