Several embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0027] Please refer to Figures 1 to 5 , the anti-freezing drainage tap in the present utility model includes a tap body 10, a three-way solenoid valve 20 and a water pipe 30. The interior of the tap body 10 is hollowed out to form a chamber. The tap body 10 is provided with a water outlet 11 and a connection port 12 that communicate with the chamber;
[0028] The three-way solenoid valve 20 includes a valve body assembly and an electromagnetic assembly 26 provided at one end of the valve body assembly. The valve body assembly is provided with a liquid inlet 22, a liquid outlet 23 and a liquid drain port 24. The liquid inlet 22 is connected to a water source through the water pipe 30, and the liquid outlet 23 is connected to the docking port 12 through the water pipe 30. The electromagnetic assembly 26 is used to control the connection between the liquid inlet 22 and the liquid outlet 23, or the connection between the liquid outlet 23 and the liquid drain port 24.
[0029] By integrating the three-way solenoid valve 20 on the water pipe 30, when the faucet is closed, only the liquid outlet 23 and the liquid drain port 24 are connected, so that the tap water inside the faucet body 10 can be discharged from the liquid drain port 24 under the action of gravity, effectively avoiding the tap water from accumulating in the chamber of the faucet body 10 and being prone to freezing, effectively overcoming the technical problem that the traditional faucet needs to be frequently maintained due to the internal tap water being prone to freezing in high-altitude and low-temperature environments.
[0030] A handle 13 is rotatably connected to the faucet body 10. An angle sensor (not shown in the figure) is provided at the rotational connection of the handle 13. Both the angle sensor and the electromagnetic assembly 26 are electrically connected to a controller (not shown in the figure). The angle sensor is used to obtain the rotation angle information of the handle 13 and send it to the controller. The controller is used to control the electromagnetic assembly 26 to be energized or de-energized according to the rotation angle information, so as to realize the connection between the liquid inlet 22 and the liquid outlet 23, or the connection between the liquid outlet 23 and the liquid drain port 24. Specifically, refer to Figure 2 , in this embodiment, two fixing seats 14 are symmetrically provided on the faucet body 10. The handle 13 is rotatably arranged between the two fixing seats 14 through a rotating shaft 15. The angle sensor is arranged on the side of the fixing seat 14 facing away from the handle 13 and is connected to the rotating shaft 15.
[0031] In practical applications, the angle sensor can real-time obtain the current rotation angle information of the handle 13 and send it to the controller. When the user rotates the handle 13 to the Figure 2 shown angle, the controller will control the electromagnetic assembly 26 to be energized, so that the liquid inlet 22 and the liquid outlet 23 of the three-way solenoid valve 20 are connected, and the liquid drain port 24 is blocked. At this time, the faucet discharges water; when the user rotates the handle 13 to the Figure 1 shown angle, the controller controls the electromagnetic assembly 26 to be de-energized, so that the liquid outlet 23 and the liquid drain port 24 of the three-way solenoid valve 20 are connected, and the liquid inlet 22 is blocked. At this time, the faucet no longer discharges water, and the water in the faucet body 10 can be discharged from the liquid drain port 24, avoiding the tap water from accumulating in the chamber of the faucet body 10 and being prone to freezing.
[0032] Refer to Figure 3 andFigure 4 The valve body assembly includes a valve body housing 21, which is a cylindrical structure as a whole. The liquid inlet 22 and the liquid outlet 24 are arranged at intervals on the lower end surface of the valve body housing 21, and the liquid outlet 23 is arranged on the upper end surface of the valve body housing 21. Among them, the central axes of the liquid inlet 22 and the liquid outlet 23 are collinear. It can be understood that the design with the collinear central axes of the liquid inlet 22 and the liquid outlet 23 enables the water flow to surge vertically and smoothly along the water pipe 30 when the user turns on the faucet, reducing the energy loss and eddy current phenomenon caused by the change of direction or the bend, helping to maintain the stability and continuity of the water flow, and making the water outlet more stable and gentle.
[0033] One end of the valve body housing 21 is provided with a plug 25, and the electromagnetic component 26 is arranged at the other end. A valve core 27 is slidably connected inside the valve body housing 21. A spring 28 is connected between the valve core 27 and the plug 25, and a valve rod 29 is connected between the valve core 27 and the electromagnetic component 26.
[0034] Under normal conditions, the electromagnetic component 26 is in a power-off state. At this time, the valve core 27 blocks the liquid inlet 22, and the faucet does not discharge water.
[0035] When the user turns the handle 13 to open the faucet, the electromagnetic component 26 is energized to contract the valve rod 29. As a result, the valve core 27 only blocks the liquid outlet 24 under the drive of the valve rod 29. At this time, the spring 28 is stretched, and the faucet discharges water. When the user turns the handle 13 to close the faucet, the electromagnetic component 26 is powered off, and the valve core 27 will reset under the elastic force of the spring 28 to block the liquid inlet 22 again.
[0036] It should be noted that the above electromagnetic component 26 is a commonly used solenoid valve component in the market. By connecting or disconnecting the power supply of the electromagnetic component 26, the generation and disappearance of electromagnetic force are controlled, and then the telescopic movement of the valve rod 29 is controlled.
[0037] Specifically, referring to Figures 3 to 5 The valve core 27 includes a first blocking component 271 and a second blocking component 272 arranged on one side of the first blocking component 271. One end of the first blocking component 271 is connected to the plug 25 through the spring 28, and the other end is connected to the electromagnetic component 26 through the valve rod 29. Among them, a channel 273 runs through the first blocking component 271 along the axis direction of the liquid inlet 22, and a drainage space 274 is formed between the second blocking component 272 and the first blocking component 271.
[0038] When the faucet is in the open state, referring to Figure 4, the first plugging member 271 is docked between the liquid inlet 22 and the liquid outlet 23, so that the liquid inlet 22 and the liquid outlet 23 are communicated through the channel 273. At this time, tap water can pass through in sequence from the liquid inlet 22, the channel 273, and the liquid outlet 23, and finally be discharged from the water outlet 11 of the faucet.
[0039] When the faucet is in the closed state, refer to Figure 3 , the first plugging member 271 deviates from the liquid inlet 22 and the liquid outlet 23, the second plugging member 272 aligns and seals the liquid inlet 22, and the liquid discharge port 24 is in an open state. At this time, tap water cannot enter the valve body housing 21 through the liquid inlet 22, so the faucet does not discharge water. In addition, if there is a certain amount of tap water in the faucet body 10, this part of tap water can, under the action of gravity, enter the valve body housing 21 in sequence from the liquid outlet 23 and the drainage space 274, and finally be discharged to the outside from the liquid discharge port 24.
[0040] Specifically, refer to Figure 5 , in an implementation manner of this embodiment, the first plugging member 271 is a cylindrical plug adapted to the shape of the valve body housing 21, the second plugging member 272 is an arc-shaped sealing plate, and the arc-shaped sealing plate is horizontally extended and formed from a part of the edge at one axial end of the cylindrical plug.
[0041] Furthermore, refer to Figure 3 and Figure 4 , a limiting member 40 is provided on the inner wall of the valve body housing 21 and is matched with the first plugging member 271. The limiting member 40 is used to limit the sliding distance of the first plugging member 271 when the electromagnetic assembly 26 is energized. When the first plugging member 271 abuts against the limiting member 40, the channel 273 on the first plugging member 271 is accurately aligned between the liquid inlet 22 and the liquid outlet 23.
[0042] In summary, the anti-freezing and drainage faucet in the above embodiment of the present utility model integrates a three-way solenoid valve 20 on the water pipe 30, so that when the faucet is closed, only the liquid outlet 23 and the liquid discharge port 24 are connected, enabling the tap water inside the faucet body 10 to be discharged from the liquid discharge port 24 under the action of gravity, effectively avoiding the tap water from accumulating in the chamber of the faucet body 10 and being prone to freezing, and overcoming the technical problem that traditional faucets need to be frequently maintained due to the internal tap water being prone to freezing in high-altitude and low-temperature environments.
