Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a shower faucet that does not retain water. Background Technology

[0002] A shower faucet is a device used to adjust the temperature and flow of the shower water. Traditionally, shower faucets mix cold and hot water through a mixing valve and then directly supply the shower head. In development, shower faucets have also been modified to include multiple shower heads or water guns to meet different needs. Similarly, a switch is installed on the shower faucet mounting base to control the water flow distribution.

[0003] A search revealed that Chinese utility model patent CN202121879226.5 discloses a bathroom shower faucet, comprising a main water supply pipe, a faucet body for controlling the water flow from the main water supply pipe, a water supply hose connected to the main water supply pipe, and a spray head connected to the water supply hose. A fixing ring plate is fixed to the faucet body, and an installation notch is provided on the fixing ring plate. A supporting outer tube is fixed to one end of the water supply hose connected to the spray head. A first clamping clamp is detachably fixed to the end of the supporting outer tube near the spray head. The water supply hose is installed inside the fixing ring plate through the installation notch, and the top surface of the fixing ring plate is engaged with the bottom surface of the first clamping clamp. This utility model allows the spray head to be engaged at different heights by moving the position of the first clamping clamp, facilitating the user to wash different areas with the shower head and improving the shower head's performance.

[0004] For example, Chinese utility model patent application number CN202320177813.2 discloses a shower head, including a hot and cold water mixing switch, a first water pipe, a soft water pipe, and a shower head connected sequentially along the water flow path; a support spring is sleeved on the middle and lower section of the soft water pipe, and the lower end of the support spring is connected to the first water pipe; the shower head includes a shower switch and a shower head, with the output end of the soft water pipe, the shower switch, and the shower head connected sequentially. The shower head provided by this utility model allows the shower head to automatically reset to a convenient position after each use without requiring manual replacement, making it easy to operate.

[0005] While the existing shower faucets can meet basic usage needs, they cannot automatically drain residual water from the handheld and overhead shower heads after the control valve is closed. Residual water continues to flow out of the pipes until it is completely drained, causing users to get wet again while drying themselves, which is extremely uncomfortable. The dripping sound from the residual water in the pipes can also disturb the user's rest. In extremely cold regions like Northeast China, the residual water in the pipes can easily freeze and crack the shower and head hoses. Utility Model Content

[0006] The technical problem this utility model aims to solve is to provide a water-free shower faucet that addresses the aforementioned deficiencies of the prior art. By providing drain outlets connected to the drainage channel on both the top spray valve core and the shower head valve core, residual water in the top spray head and shower head can be discharged sequentially through the drain outlet, drainage channel, and bottom outlet under the action of gravity and constant suction. This ensures that there is no residual water in the pipes, solves the problem of residual water leakage, and reduces and avoids freezing and cracking of the shower pipe and shower head. At the same time, it prevents users from experiencing prolonged periods of cold water when the shower faucet is turned on, resulting in a better user experience.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A non-water-storing shower faucet includes a shower body. The shower body is equipped with a lower water outlet valve core, a top spray water outlet valve core, a shower head water outlet valve core, and a temperature-adjustable mixing valve core. The lower water outlet valve core, top spray water outlet valve core, and shower head water outlet valve core are respectively connected to a lower water outlet head, a top spray water outlet head, and a shower head water outlet head. The temperature-adjustable mixing valve core is connected to several water inlet pipes. The lower water outlet valve core, top spray water outlet valve core, and shower head water outlet valve core are all connected to the temperature-adjustable mixing valve core. A drainage channel connected to the lower water outlet head is provided within the shower body. Drainage outlets are provided on both the top spray water outlet valve core and the shower head water outlet valve core, and these drainage outlets are connected to the drainage channel.

[0009] Preferably, the bottom of the shower body is provided with a lower water outlet mounting hole, and the lower water outlet is installed in the lower water outlet mounting hole.

[0010] Preferably, the front end of the shower body is provided with a lower water outlet switch, a top spray water outlet switch, and a shower head water outlet switch, which are respectively connected to the lower water outlet valve core, the top spray water outlet valve core, and the shower head water outlet valve core. The side of the shower body is provided with a temperature control switch connected to the temperature control mixing valve core.

[0011] Preferably, the water inlet pipe includes a hot water inlet pipe and a cold water inlet pipe, both of which are located at the rear end of the shower body.

[0012] Preferably, the rear ends of the top spray valve core and the shower head valve core are provided with a water inlet hole, a water outlet hole and a drain outlet, and the water inlet hole, the water outlet hole and the drain outlet are arranged in a triangular pattern with the vertices of the triangle distributed sequentially.

[0013] Preferably, both the top spray valve core and the shower head valve core are equipped with rotating water-blocking ceramic discs, and the water inlet and outlet are adapted to the rotating water-blocking ceramic discs.

[0014] By adopting the above technical solution, the present invention provides a non-water-retaining shower faucet, which has the following beneficial effects: The shower body of the shower faucet is equipped with a lower water outlet valve core, a top spray water outlet valve core, a shower head water outlet valve core, and a temperature-adjusting mixing valve core. The lower water outlet valve core, the top spray water outlet valve core, and the shower head water outlet valve core are respectively connected to a lower water outlet head, a top spray water outlet head, and a shower head water outlet head. The temperature-adjusting mixing valve core is connected to several water inlet pipes. Both the valve core and the shower head outlet valve core are connected to the temperature-regulating mixing valve core. The shower body has a drainage channel connected to the lower water outlet. Both the overhead spray outlet valve core and the shower head outlet valve core have drain ports connected to the drainage channel. By having drain ports on both the overhead spray outlet valve core and the shower head outlet valve core connected to the drainage channel, residual water in the overhead spray head and the shower head can be sequentially drained through the drain ports, the drainage channel, and the lower water outlet under the influence of gravity. The shower head is automatically drained. When the shower head valve is open, water flows normally. When the shower head valve is closed, the water flows back under gravity and is discharged through the drain port on the shower head valve, automatically emptying the residual water in the pipe. Similarly, when the overhead shower valve is open, water flows normally. When the overhead shower valve is closed, the water flows back under gravity and is discharged through the drain port on the overhead shower valve, automatically emptying the residual water in the pipe. This achieves automatic drainage of residual water from the handheld and overhead showers, preventing water from accumulating and ensuring no water remains in the pipes. This solves the problem of residual water dripping, avoiding getting wet or making a dripping sound, resulting in a better user experience. In extremely cold regions like Northeast China, it prevents residual water in the pipes from freezing and cracking the shower pipes, and also prevents users from experiencing cold water for extended periods when the shower faucet is turned on.

[0022] like Figure 1-3 As shown, the non-water-holding shower faucet includes a shower body 1. The shower body 1 is equipped with a lower water outlet valve core 2, a top spray water outlet valve core 3, a shower head water outlet valve core 4, and a temperature-adjusting mixing valve core 5. The lower water outlet valve core 2, the top spray water outlet valve core 3, and the shower head water outlet valve core 4 are respectively connected to a lower water outlet head 6, a top spray water outlet head 7, and a shower head water outlet head 8. The temperature-adjusting mixing valve core 5 is connected to several water inlet pipes. The lower water outlet valve core 2, the top spray water outlet valve core 3, and the shower head water outlet valve core 4 are all connected to the temperature-adjusting mixing valve core 5. The shower body 1 is provided with a drainage channel 11 that is connected to the lower water outlet head 6. The top spray water outlet valve core 3 and the shower head water outlet valve core 4 are each provided with a drain outlet 12, which is connected to the drainage channel 11. Understandably, the shower body 1 can be made of stainless steel or the like; the overhead spray head 7 can be a general overhead spray head or the shower head 8 can be a general shower head or the like, and they are all connected to the shower body 1 through a shower pipe.

[0023] Specifically, the shower body 1 has a bottom outlet mounting hole 13, and the bottom outlet 6 is installed in the bottom outlet mounting hole 13; the front end of the shower body 1 is provided with a bottom outlet switch 14, a top spray outlet switch 15, and a shower outlet switch 16, which are respectively connected to the bottom outlet valve core 2, the top spray outlet valve core 3, and the shower head outlet valve core 4; the side of the shower body 1 is provided with a temperature control switch 17 connected to the temperature control mixing valve core 5; the water inlet pipe includes a hot water inlet pipe 9 and a cold water inlet pipe 10, which are both located at the rear end of the shower body 1.

[0024] Specifically, the rear ends of the top spray water valve core 3 and the shower head water valve core 4 are provided with a water inlet hole 18, a water outlet hole 19 and a drain outlet 12. The water inlet hole 18, the water outlet hole 19 and the drain outlet 12 are arranged in a triangular pattern with the vertices of the triangle distributed in sequence. The top spray water valve core 3 and the shower head water valve core 4 are provided with a rotating water-blocking ceramic disc 20. The water inlet hole 18 and the drain outlet 12 are adapted to the rotating water-blocking ceramic disc 20. Understandably, when the above-mentioned top spray water outlet valve core 3 and shower head water outlet valve core 4 are opened, the rotating water-blocking ceramic disc 20 blocks the drain port 12. At this time, the water inlet hole 18 and the water outlet hole 19 are connected, which is the normal water outlet state. When the above-mentioned top spray water outlet valve core 3 and shower head water outlet valve core 4 are closed, the rotating water-blocking ceramic disc 20 blocks the water inlet hole. At this time, the drain port 12 and the water outlet hole 19 are connected, which is the state of discharging residual water. The lower water outlet head 6 itself is open downwards, and finally the residual water enters the lower water outlet head 6 through the drainage channel, and is discharged from the lower water outlet head 6.

[0025] Understandably, this utility model has a reasonable design and unique structure. By providing drain ports 12 connected to the drainage channel 11 on both the top spray valve core 7 and the shower head valve core 4, residual water in the top spray head 7 and the shower head 8 can be discharged sequentially through the drain ports 12, the drainage channel 11, and the lower outlet head 6 under the action of gravity. When the shower head valve core 4 is opened, the shower head 8 dispenses water normally. When the shower head valve core 4 is closed, the water in the shower head 8 flows back under the action of gravity and is discharged through the drain ports 12 on the shower head valve core 4, automatically emptying the residual water in its pipe. When the top spray valve core 3 is opened, the top spray water... When the shower head 7 is in normal use, and the top spray valve core 3 is closed, the water in the top spray head 7 flows back under gravity and is discharged through the drain port 12 on the top spray valve core 3, automatically emptying the residual water in its pipe. This achieves the effect of automatically emptying the residual water in the handheld shower head and the top spray head, eliminating water retention and ensuring that there is no residual water in the pipe. This solves the problem of residual water dripping and avoids getting wet or making a dripping sound due to residual water dripping, resulting in a better user experience. When used in extremely cold regions such as Northeast China, it can prevent the residual water in the pipe from freezing and cracking the shower pipe, and also prevents users from having cold water coming out for a long time when they turn on the shower faucet.
