Description

Technical Field

[0001] The utility model relates to the field of faucets, and in particular to an anti-freezing bathroom faucet. Background Art

[0002] The anti-freezing performance of a faucet refers to its ability to prevent the internal water from freezing in a low-temperature environment. This performance is particularly important for faucets in cold regions. The faucet is closed by isolating the water in the water valve and the water pipe. In a low-temperature environment, when the water freezes, due to the volume change, it will be squeezed, which is likely to cause cracks on the surface of the faucet to be damaged and the internal structure to be deformed, resulting in water dripping from the faucet (the anti-freezing faucets with publication numbers CN209325077U and CN201554888U also have relevant descriptions in the background art). The purpose of the utility model is to improve the existing faucet structure and propose a new faucet to solve the above technical problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an anti-freezing bathroom faucet to solve the problems mentioned in the background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: It includes a faucet main body, a first valve seat, a cavity, a second valve seat and a second valve stem. A valve body is provided on the faucet main body, a first valve stem is installed on the valve body, and a handle connected to the valve body is installed above the faucet. The first valve seat is formed inside the faucet main body. A first valve core that can abut against the first valve seat is formed on the first valve stem. The cavity is connected to the faucet main body and is located below the first valve seat. A drain pipe communicating with the outside is formed at the bottom of the cavity. A connecting ring is formed at the bottom of the first valve core, and a sealing ring is arranged at the bottom of the connecting ring. The sealing ring can move down to cover the drain pipe. The second valve seat is located below the cavity and is connected to the faucet main body. The top end of the second valve stem is connected to the bottom end of the first valve stem, and a second valve core that can abut against the second valve seat is provided at the bottom of the second valve stem.

[0005] To optimize the above technical solution, a further measure is taken: Through holes are formed on the side surface of the connecting ring, and the through holes can allow water flow to pass through, avoiding the connecting ring from affecting the water outlet of the faucet.

[0006] As a further improvement of the above technical solution: The top end of the second valve stem is connected to the bottom end of the first valve stem to form a spherical pair, and its purpose is to prevent the second valve stem from being bent by the extrusion of ice cubes and being unable to cooperate with the second valve seat.

[0007] From the above description of the structure of the utility model, compared with the prior art, the utility model has the following advantages:

[0008] An anti-freezing bathroom faucet provided by the utility model forms an independent space within the faucet body to isolate the internal structure of the faucet from the water pipe by setting a double valve stem and a double valve core. Meanwhile, the remaining water can be discharged from the drain pipe, avoiding the volume change and extrusion deformation caused by the freezing of water in the valve body and valve stem in a low-temperature environment, and preventing the faucet from being damaged.

[0013] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0014] Embodiment

[0015] Please refer to Figure 1 and Figure 2 , the utility model provides an anti-freezing bathroom faucet, including a faucet body 1, a first valve seat 2, a cavity 3, a second valve seat 4 and a second valve stem 5. A valve body 101 is arranged on the faucet body 1, a first valve stem 102 is installed on the valve body 101, and a handle 103 connected to the valve body 101 is installed above the faucet.

[0016] The first valve seat 2 is formed within the faucet body 1, and a first valve core 201 capable of abutting against the first valve seat 2 is formed on the first valve stem 102.

[0017] The cavity 3 is connected to the faucet body 1. The cavity 3 is located below the first valve seat 2. A drain pipe 301 communicating with the outside is formed at the bottom of the cavity 3. A connecting ring 302 is formed at the bottom of the first valve core 201. Through holes 304 are formed on the side surface of the connecting ring 302. A sealing ring 303 is arranged at the bottom of the connecting ring 302. The sealing ring 303 can move downward to cover the drain pipe 301.

[0018] The second valve seat 4 is located below the cavity 3 and is connected to the faucet body 1.

[0019] The top end of the second valve stem 5 is connected to the bottom end of the first valve stem 102 to form a spherical pair. A second valve core 501 that can abut against the second valve seat 4 is arranged at the bottom of the second valve stem 5.

[0020] Working principle: Rotate the handle 103 clockwise to move the first valve core 201 and the second valve core 501 downward. At this time, the sealing ring 303 covers the drain pipe 301, so that water flow cannot pass through the drain pipe 301, and the water flow can leave from the water outlet of the faucet body 1 through the through holes 304 on the connecting ring 302.

[0021] Rotate the handle 103 counterclockwise to move the first valve core 201 and the second valve core 501 upward. At this time, the sealing ring 303 no longer covers the drain pipe 301 and the second valve core 501 abuts against the second valve seat 4 to isolate the valve body 101, the first valve stem 102 and the second valve stem 5 from the water pipe. The water in the cavity 3 can flow from the drain pipe 301 to the outside of the faucet body 1, which can prevent the valve body 101, the first valve stem 102 and the second valve stem 5 in the faucet body 1 from being damaged due to ice formation in a low-temperature environment.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
