Description

Shower faucet with cold water discharging function and shower

Technical Field

The utility model relates to a tap, in particular to a shower tap with a cold water discharging function and a shower.

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 shower faucet does not have the cold water discharging function, and when cold water is required to be discharged, a user is required to repeatedly test the water temperature for a plurality of times by means of manually starting the cold water discharging and controlling the cold water discharging time, so that the shower faucet is troublesome to use. Therefore, the prior art has a plurality of shower faucets with the cold discharging function, and can be divided into two types, one type adopts an electronic mode for cold discharging, and the defects of higher cost and short service life exist. Another type is to realize cold discharge by adopting a mechanical structure, for example, chinese patent 201521135958.8 discloses a switching valve with cold discharge function, which comprises a valve body, a valve core and a temperature sensing module set in the valve body, wherein the valve body is provided with a water inlet channel, 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 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. Such a switching valve with a cold discharge function can naturally realize the cold discharge function, 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 cooling is completed, the hole of the cooling channel is blocked, but the air suction hole is not blocked, and water may enter the second water outlet channel from the air suction hole, so that water leakage occurs.

When pre-cooling is needed, the switch member 33 is pressed down, the switch member 33 drives the sealing rod 32 to move backward against the elastic force of the first elastic member 34 and the second elastic member 35 to open the pressure relief hole 3111 on the water stop member 31, water in the back pressure chamber 115 flows from the pressure relief hole 3111 to the water discharge chamber 116 (as shown in fig. 8 and 9), and is discharged from one of the water outlet terminals (such as top spray or hand shower) connected with the water diversion valve core 5, so that the water pressure of the back pressure chamber 115 is greatly reduced, and at the moment, the water pressure in the positive pressure chamber 114 is far greater than the water pressure of the back pressure chamber 115, so that the water stop member 31 moves in the direction of the back pressure chamber 115 under the pushing of the water pressure in the positive pressure chamber 114, thereby opening the communication opening 117, and cold water in the water inlet pipeline flows to the water discharge chamber 116 sequentially through the water outlet chamber 113, the positive pressure chamber 114 and the communication opening 117, and finally is discharged from one of the water outlet terminals connected with the water diversion valve core 5, as shown in fig. 10 and 11. In the cold discharge process, the water in the positive pressure cavity 114 is gradually supplemented into the back pressure cavity 115 from the damping hole 3112 on the water stop member 31, so that the water pressure in the back pressure cavity 115 is gradually increased until the water pressure is equal to the water pressure in the positive pressure cavity 114, at this time, the water stop member 31 moves and resets in a direction away from the back pressure cavity 115 under the pushing of the water pressure in the back pressure cavity 115 and the restoring force of the first elastic member 34, thereby closing the communication port 117 and completing the cold discharge process.

Therefore, the utility model can automatically complete the cold discharging process by only pressing the switch element 33 when the user takes a shower, and can automatically reset after cold discharging without manually controlling the water discharging time and the water discharging amount by the user.

The switch component of the shower faucet with the cold discharging function can also play a role in switching water during shower, specifically, after the cold discharging end, when a user needs to take a shower, the user only needs to press down the switch component 33 and rotate a certain angle, so that the first positioning block 331 on the switch component 33 is clamped by the second positioning block 831 in the front cover 83, the sealing rod 32 and the switch component 33 are limited to be automatically reset under the action of the second elastic component 35 and the third elastic component 36, the sealing rod 32 is kept in a state of opening the pressure relief hole 3111, the water stopping component 31 is kept in a state of opening the communication opening 117, as shown in fig. 12 and 13, warm water is sequentially left in the water discharging cavity 116 from the water outlet cavity 113, the positive pressure cavity 114 and the communication opening 117, and finally discharged from one of water outlet terminals connected with the water distributing valve core 5, and the shower function is realized. When the user finishes the shower, the switch member 33 is reversely rotated, so that the first positioning block 331 on the switch member 33 is released by the second positioning block 831 in the front cover 83, and the sealing rod 32 and the switch member 33 are gradually reset, and the water stopping member 31 gradually closes the communication port 117, thereby finally achieving the water stopping function. Therefore, the shower faucet disclosed by the utility model does not need to be additionally provided with a switch valve core, so that the overall structure is more compact and the cost is lower.

Referring to fig. 1 to 14, the shower of the present utility model includes the shower faucet with cold water draining function and a plurality of water outlet terminals, wherein the water outlet terminals specifically include a hand shower 10 and a top shower 20, and the hand shower 10 and the top shower 20 are respectively connected to two water outlets of the water diversion valve core 5, so that water is drained from the water diversion valve core 5.

The present utility model relates to a shower faucet structure with cold water draining function and its operating principle, and the description thereof is omitted herein.

The shower faucet with the cold water discharging function and the shower are not related to the shower faucet with the cold water discharging function, which are the same as or can be realized by adopting the prior art.
