The shower faucet is one of the indispensable equipment in the bathroom. The constant temperature of the shower faucet is usually adjusted manually by the user. The adjustment method is that the user manually adjusts the regulating valve to change the ratio of hot water to cold water, so as to achieve the water sprayed from the shower head at the appropriate temperature.

DETAILED DESCRIPTION

[0026] like Figures 1 to 8 As shown, the embodiment of the utility model provides a shower faucet, comprising a main rod 1, a water inlet rod 2, a shower head 3 and a manual valve 4, wherein one end of the main rod 1 is connected to the water inlet rod 2, and the other end of the main rod 1 is connected to the shower head 3;

[0027] A hot water inlet pipe 7 and a cold water inlet pipe 8 are provided inside the water inlet rod 2, one end of the manual valve 4 is connected to the hot water inlet pipe 7, and the other end of the manual valve 4 is connected to the cold water inlet pipe 8;

[0028] Usually, the user adjusts the ratio of cold water to hot water through the manual valve 4 so as to keep the water temperature of the shower head 3 constant. However, when the user is taking a shower, the water in the cold water pipe suddenly decreases, and the user does not have time to react and manually adjust the ratio of cold water to hot water through the manual valve 4, and is easily scalded by the high proportion of hot water in the shower head.

[0029] A shower head cooling device 10 is installed on the top of the shower head 3, and the shower head cooling device 10 is used to reduce the temperature of the shower head 3;

[0030] A main pipe 6 is arranged inside the main rod 1, one end of the main pipe 6 is connected to the shower head 3, the other end of the main pipe 6 is connected to the manual valve 4, and an automatic electric valve 6 is installed in the middle of the main pipe 6;

[0031] A cooling device power supply 13 and a cooling device controller 15 are installed on the top of the shower head cooling device 10;

[0032] The hot water inlet pipe 7 and the cold water inlet pipe 8 are both provided with sensor installation grooves, and a water flow sensor 11 and a water temperature sensor 12 are installed in the sensor installation grooves.

[0033] Specifically, the connection lines of the water flow sensor 11 and the water temperature sensor 12 pass through the outer wall of the water inlet rod 2 and are connected to the cooling device controller 15, and a sealing layer is provided at the connection lines of the water flow sensor 11 and the water temperature sensor 12 passing through the outer wall of the water inlet rod 2. The water temperature sensor 12 collects water temperature data and transmits it to the cooling device controller 15, and the water flow sensor 11 collects water flow data and transmits it to the cooling device controller 15.

[0034] Specifically, an automatic electric valve connection line 9 is connected between the automatic electric valve 5 and the cooling device controller 15. The cooling device controller 15 transmits control commands such as start or close to the automatic electric valve 5.

[0035] Specifically, the shower head cooling device 10 includes a heat dissipation layer 1001, a first heat-conducting metal layer 1002, an insulating layer 1003, a second heat-conducting metal layer 1004 and a semiconductor 1005;

[0036] The first heat-conducting metal layer 1002 is disposed on one side of the semiconductor 1005, the second heat-conducting metal layer 1004 is disposed on the other side of the semiconductor 1005, and the insulating layer 1003 is disposed on the outer wall of the second heat-conducting metal layer 1004. The insulating layer 1003 is used to isolate the current generated by the shower head cooling device 10, and the heat dissipation layer 1001 is used to dissipate heat.

[0037] In order to quickly cool the water sprayed from the faucet, semiconductor refrigeration technology can be used. This technology is based on the thermoelectric effect, especially the Peltier effect, which controls the size of the current to achieve heat transfer, thereby achieving the effect of rapid cooling. Specifically, when the current passes through the semiconductor material, heat transfer occurs, making one end of the semiconductor cold and the other end hot. Using this phenomenon, the water flowing out of the faucet can be quickly cooled through the semiconductor cooling sheet.

[0038] The faucet semiconductor refrigeration technology is a refrigeration technology based on the thermoelectric effect (especially the Peltier effect). Simply put, this technology achieves the purpose of refrigeration by controlling the size of the current to achieve heat transfer.

[0039] Specifically, the working principle of semiconductor refrigeration is to utilize the thermoelectric effect of semiconductor materials. When current passes through semiconductor materials, heat transfer occurs due to the special properties of semiconductor materials. At one joint (cold end), the first heat-conducting metal layer 1002 absorbs heat when current passes through it, lowering its temperature and achieving a cooling effect. At the same time, at another joint (hot end), the second heat-conducting metal layer 1004 releases heat when current passes through it.

[0040] The utility model provides a method for using a shower faucet as follows: when a user uses the shower head to take a shower normally, the manual valve 4 remains fixed, the temperatures of the hot water inlet pipe 7 and the cold water inlet pipe 8 remain unchanged, and when the cold water entering decreases, the water temperature sensor 12 and the water flow sensor 11 located in the cold water inlet pipe 8 transmit data to the cooling device controller 15. After the cooling device controller 15 obtains that the cold water flow in the cold water inlet pipe 8 decreases, the automatic electric valve 5 is activated to reduce the water flow in the main pipe 6, and the shower head cooling device 10 is activated. The shower head cooling device 10 cools the shower head 3. The temperature is lowered to reduce the temperature of the water sprayed from the shower head 3 as much as possible to prevent the water sprayed from the shower head 3 from scalding the user. When the water flow in the cold water inlet pipe 8 is normal, the automatic electric valve 5 is reset, and the shower head cooling device 10 stops cooling the shower head 3. The technical solution of the present application solves the problem that when other equipment suddenly uses a large amount of cold water, the cold water in the shower head pipe is occupied, but the water flow of the hot water in the shower head pipe remains unchanged. Since the regulating valve does not change, the cold water in the water sprayed from the shower head is reduced, which causes the temperature of the water sprayed from the shower head to be too high, causing the skin of the shower head user to be scalded by the water.

For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
