Problems solved by technology

[0002] At present, the water diversion valves on the market can only realize the function of switching water channels, and do not have the ability to drain the residual water in the pipeline connected to the rear end of the water diversion valve.
For example, for a flushable toilet cover, after flushing, there will generally be residual water in the flushing pipe behind the diverter valve. If there is water residue in the pipe for a long time, it is easy to breed bacteria. Only when it is drained will the warm water flow out, the residual cold water will touch the human body first and cause discomfort, especially in winter, it is more unacceptable, and the residual water is easy to

Example

[0062] The first embodiment (water diversion valve includes water passage and drain channel)

[0063] Such as Figure 1 to Figure 12 As shown, the water diversion valve with drain function of this embodiment includes a water passage and a drain channel. When the water diversion valve is opened, the water passage is opened and the drain channel is closed, and water flows through The water passage of the water diversion valve flows into the outlet pipe connected to the rear end of the water diversion valve; when the water diversion valve is closed, the water passage is closed and the drain channel is opened to connect the water outlet at the rear end of the water diversion valve. The residual water in the pipeline is drained through the drain channel.

[0064] In this embodiment, the water diversion valve includes a valve body 100 and a valve core. The valve body 100 is provided with a water inlet 110, a water outlet, and a water discharge port 140. The valve core includes fittings t...

Example

[0069] Second embodiment (water diversion valve includes a water passage, a return passage, and a drain passage)

[0070] Such as Figure 13 to Figure 24 As shown, in this embodiment, the main difference from the water diversion valve of the above-mentioned first embodiment is that it further includes a return channel, which includes a return water outlet 150, a return water inlet 160, A return pipe 700 that is connected to the valve body 100 and communicates with the return water outlet 150 and the return water inlet 160, and the first valve plate 200 is provided with a return water outlet hole communicating with the return water outlet 150 240. The backflow water inlet 250 communicating with the backflow water inlet 160, and the second valve plate 300 is provided with a backflow groove 350 communicating with the backflow water inlet 250, and the backflow groove 350 and The drain groove 322 and the outlet groove communicate with each other.

Abstract

The invention discloses a shunt valve with a water release function and a closestool cover plate provided with the shunt valve. The shunt valve comprises a water passing channel and a water release channel. When flushing is started, the water passing channel is opened and the water release channel is closed. After the flushing is completed, the water passing channel is closed and the water release channel is opened, and residual water in a pipeline connected with a downstream part of the shunt valve is released through the water release channel, so that bacteria breeding due to long-time accumulated water is avoided; in addition, the problem that the cooler residual water touches a human body first and leads to discomfort when the water passes a closestool using the shunt valve every time can be solved; and the closestool is healthier and more comfortable.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a water diversion valve with a drain function and a toilet cover with the water diversion valve. Background technique [0002] At present, the water diversion valves on the market can generally only realize the function of switching water channels, and do not have the ability to drain the residual water in the pipeline connected to the rear end of the water diversion valve. For example, for a flushable toilet cover, when the flushing is over, there will generally be residual water in the flushing pipe behind the diverter valve. If there is water residue in the pipe for a long time, it is easy to breed bacteria. Only when it is drained will the warm water flow out, the residual cold water will touch the human body first and cause discomfort, especially in winter, it is more unacceptable, and the residual water is easy to breed bacteria in the pipeline, so it is also very har...
