Description

Cold discharging valve core and valve using same

Technical Field

The utility model relates to a arrange valve core of cold and use valve of this case.

Background

When people take a shower, particularly in winter, people need to drain cold water remained in the pipeline first, and take a shower after warm water comes out. In the traditional cold drainage mode, a user cuts off drainage time and/or feels water temperature with skin by depending on experience to judge whether residual water is drained or not, so that inaccurate judgment is easily caused, once the drainage time is too long, water resources are wasted, and the residual water cannot be drained when the drainage time is too short; the user repeatedly tests the water temperature for many times, which causes trouble in use.

The chinese utility model 201521135958.8 discloses a switching valve with a cold discharge function, which comprises a valve body, a valve core and a temperature sensing module, wherein the valve core and the temperature sensing module are arranged in the valve body, the valve body is provided with a water inlet channel, namely a first water outlet channel and a second water outlet channel which are respectively communicated with the water inlet channel; the valve body is also provided with a cold discharge channel communicated with the water inlet channel, a drain hole communicated with the first water outlet channel and the cold discharge channel, and an air suction hole communicated with the second water outlet channel and the cold discharge channel, and the temperature sensing module is used for opening and closing the drain hole. When the cold water is discharged, the valve core closes the first water outlet channel and the second water outlet channel, water enters the cold water discharge channel from the water inlet channel, water flow generates suction force to suck cold water remained in the second water outlet channel into the cold water discharge channel along the suction hole, and the water passes through the water discharge hole and is discharged from the water outlet of the first water outlet channel together with the cold water remained in the first water outlet channel; when the water temperature rises to a preset value, the temperature sensing module closes the drain hole and finishes the cold draining.
