Background
When people take a shower, especially in winter, the cold water remained in the pipeline is drained first, and the shower is performed after warm water comes out. The traditional cold drainage mode is that a user stops draining time and/or perceives water temperature with skin by experience to judge whether residual water is drained, so that inaccurate judgment is easy to cause, once the draining time is too long, water resource waste is caused, and when the draining time is too short, the residual water cannot be drained completely; the user repeatedly tries the water temperature for many times, which causes the trouble of use.
The Chinese patent 201521135958.8 discloses a switching valve with a cold discharging 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 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 switching on and off the drain hole. When the valve core discharges cold, the first water outlet channel and the second water outlet channel are closed, water enters the cold discharge channel from the water inlet channel, the water flow generates suction force to suck cold water remained in the second water outlet channel into the cold discharge channel along the suction hole, and the water is discharged from the water outlet of the first water outlet channel together with the cold water remained in the first water outlet channel after passing through the water discharge hole; when the water temperature rises to a preset value, the temperature sensing module closes the water drain hole, and the cooling is finished.
The above-mentioned switching valve with cold discharging function can realize cold discharging function naturally, but also has the following disadvantages: the difficulty in discharging the cold water of the second water outlet channel is too great through the venturi principle; when the cold discharge is completed, the hole of the cold discharge channel is blocked, but the air suction hole is not blocked, water possibly enters the second water outlet channel from the air suction hole, and water leakage occurs; after the cooling is finished, the temperature sensing module thermally expands to temporarily close the water drain hole, but the valve core needs to be manually switched to other positions to be completely closed, so that the operation is inconvenient because of two operations.

The invention relates to a cold-discharging automatic reset valve core, which has two states, wherein the first state is shown in fig. 8, and at the moment, a sealing gasket 32 blocks a communication port 112 to enable a drainage channel 11 to be in a closed state; the elastic force of the first spring 44 is zero, and the second spring 45 urges the gasket 32 to maintain the state of blocking the communication port 112. The second state of the present invention is a cool-discharging state, as shown in fig. 9, in which the drain passage 11 is opened.
In the first state, when the ratchet wheel 42 is pressed, the ratchet wheel 42 moves downward, and at the initial stage of the downward movement of the ratchet wheel 42, since the elastic force of the first spring 44 is smaller than that of the second spring 45, the ratchet wheel 42 and the rotating wheel 43 move downward, and the water control member 3 remains stationary. As the rotating wheel 43 continues to move downwards, the first spring 44 is gradually compressed until the other end of the central shaft 31 (i.e. the top end of the upper shaft 311) passes through the first through hole 434 of the rotating wheel 43 and abuts against the inner top surface of the ratchet wheel 42, at this time, the water control member 3 moves downwards together with the rotating wheel 43 and the ratchet wheel 42, and the second spring 45 is gradually compressed, when the extension piece 433 of the rotating wheel 43 exits the first guide slot 411 of the ratchet wheel seat 41 downwards, the rotating wheel 43 rotates relative to the ratchet wheel 42 under the cooperation of the upper ratchet 431 of the rotating wheel 43 and the first ratchet 421 of the ratchet wheel 42, so that the extension piece 433 abuts against the intersection of the first inclined surface 414 and the second inclined surface 415 of the ratchet wheel seat 41, thereby limiting the water control member 3 to move upwards under the action of the second spring 45, and at this time, the sealing gasket 32 leaves the communication port 112, thereby opening the water discharge channel 11, which is the second state of the invention. In the second state, when the ratchet wheel 42 is pressed down again, the ratchet wheel 42 pushes the rotating wheel 43 downward, the rotating wheel 43 rotates a certain angle and is acted by the first spring 44 to enable the extending block 433 to return to the first guide groove of the ratchet wheel seat 41 again, and meanwhile, the water control member 3 moves upwards under the action of the second spring 45, so that the drainage channel 11 is closed, and the manual reset is realized. In the second state, when cold water flows into the drain passage 11, the temperature sensing rod 21 is not elongated, the drain passage 11 is kept in an open state, and cold water is discharged from the drain passage 11; when the water temperature reaches the lowest threshold value of the temperature sensing rod 21, the temperature sensing rod 21 starts to be heated and expanded, and after the temperature sensing rod 21 stretches to a certain length, the temperature sensing rod 21 starts to push the central shaft 31 upwards, the top wheel 5 moves upwards along with the temperature sensing rod, the third ratchet teeth 51 of the top wheel 5 act on the lower ratchet teeth 432 of the rotating wheel 43 along with the upward movement of the top wheel 5, the rotating wheel 43 rotates by a certain angle, the extending block 433 of the rotating wheel rotates out along the third inclined surface 416 and returns to the first guide groove of the ratchet seat 41 again under the action of the first spring 44, meanwhile, the water control piece 3 moves upwards under the action of the second spring 45, so that the water drainage channel 11 is closed, the cold drainage is finished, and automatic reset is realized. Therefore, when the cooling is performed, the user only needs to press the ratchet wheel 42 once, and after the cooling is finished, the valve core automatically resets, and the cooling process is finished.
The shower faucet comprises a faucet body, a water temperature regulating valve core and a water outlet control valve core which are arranged on the faucet body, and the automatic cold discharging reset valve core disclosed by the invention is arranged on the faucet body, and the inlet of a water discharging channel 11 of the automatic cold discharging reset valve core and the water inlet of the water outlet control valve core are respectively communicated with a mixed water outlet of the water temperature regulating valve core.

The water temperature adjusting valve core is a constant temperature valve core, but is not limited to the same, and in other embodiments, the water temperature adjusting valve core is a common water mixing valve core. The water outlet control valve core is a switch valve core, but is not limited to this, and in other embodiments, the water outlet control valve core is a water diversion valve core.
