Description

Technical Field

[0001] This invention relates to the field of water intake equipment technology, and in particular to antifreeze components for faucets. Background Technology

[0002] A faucet is a common water dispensing device accessory, mainly used to control the flow of water. In environments below 0°C, faucets and the water pipes connected to them are prone to freezing, and sometimes the water pipes may even crack due to freezing. Summary of the Invention

[0003] The purpose of this invention is to provide an antifreeze component for faucets, which solves one or more of the problems of the prior art mentioned above.

[0004] This invention proposes an antifreeze component for faucets. The antifreeze component is connected to the bottom of a horizontally positioned pipe and communicates with the inside of the pipe. The antifreeze component is disposed within an antifreeze cavity, and the bottom of the antifreeze cavity is provided with a drain outlet.

[0005] The antifreeze component for the faucet includes a metal spring, a lever assembly, and a plug connected to the lever assembly for blocking the drain outlet. One side of the metal spring is connected to the cavity wall of the antifreeze chamber, and the other side is correspondingly set to the lever assembly.

[0006] In some embodiments, the conduit is located on a faucet or on a water pipe connected to a faucet.

[0007] In some embodiments, the pipe is located on one side of the faucet where it connects to the water pipe, and the other side of the faucet is the water outlet.

[0008] In some embodiments, the antifreeze component for the faucet is either fixedly connected to or detachably connected to the pipe.

[0009] In some embodiments, the metal spring is a bimetallic spring.

[0010] In some embodiments, the lever assembly includes a central shaft and a lever sleeved on the central shaft, with the metal spring plate disposed on the upper part of the lever on one side of the central shaft, and the other end of the central shaft connected to a plug via a connecting rod.

[0011] In some embodiments, when the metal spring is not in operation, the metal spring is arranged parallel to the lever.

[0012] In some embodiments, the distance between the metal spring and the lever is greater than 0.5 mm and less than 3 mm.

[0013] In some implementations...

[0014] The lever assembly is made of food-grade plastic or food-grade stainless steel.

[0015] The advantages of the antifreeze component for faucets described in this invention are:

[0016] With a simple structure, when the temperature drops below 0℃, the metal spring bends downward and acts on the lever assembly, thereby opening the plug using the lever principle. Water flows out through the drain, ensuring that the water remaining in the pipes and faucet continues to flow, preventing the faucet and the water pipes connected to it from freezing, and ensuring the service life of the faucet and the water pipes connected to it.

[0020] Combination Figure 1 and Figure 2 The present invention discloses an antifreeze component for a faucet. The antifreeze component is connected to the bottom of a horizontally positioned pipe 2 and to the water transport channel inside the pipe 2. The antifreeze component is disposed within an antifreeze cavity, and a drain outlet is provided at the bottom of the antifreeze cavity.

[0021] The antifreeze component for the faucet includes a metal spring 401, a lever assembly, and a plug 405 connected to the lever assembly for blocking the drain outlet. One side of the metal spring 401 is connected to the cavity wall of the antifreeze chamber, and the other side is correspondingly set to the lever assembly.

[0022] Pipe 2 is installed on faucet 1 or on a water pipe connected to faucet 1.

[0023] When pipe 2 is installed on faucet 1, it is generally installed on the side of faucet 1 that is connected to the water pipe, and the other side of faucet 1 is the water outlet.

[0024] The antifreeze component of the faucet is either fixedly connected to pipe 2 or detachably connected.

[0025] The aforementioned metal shrapnel 401 can be a bimetallic shrapnel.

[0026] The lever assembly includes a central shaft 403 and a lever 402 sleeved on the central shaft 403. A metal spring 401 is provided on the upper part of the lever 402 on one side of the central shaft 403. The other end of the central shaft 403 is connected to a plug 405 through a connecting rod 404. When the metal spring 401 is not working, the metal spring 401 is arranged parallel to the lever 402.

[0027] The distance between the metal spring 401 and the lever 402 is greater than 0.5 mm and less than 3 mm.

[0028] The lever assembly is made of food-grade plastic (plastic that will not leach harmful substances under normal and high-temperature conditions) or food-grade stainless steel (stainless steel material that meets the latest national standard GB4806.9-2016 and is truly safe for contact with food without causing harm to the body).

[0029] Example 1

[0030] Taking pipe 2 installed on faucet 1 as an example, combined with Figure 1 As shown, the antifreeze component for the faucet is fixedly connected to the pipe 2. The bottom of the pipe 2 is recessed to form a first antifreeze cavity 3, and the antifreeze component for the faucet is installed in the first antifreeze cavity 3.

[0031] Example 2

[0032] Taking pipe 2 installed on faucet 1 as an example, combined with Figure 2 As shown, the antifreeze component for the faucet is detachably connected to the pipe 2. The bottom of the pipe 2 is provided with a connecting section. The housing 5 and the connecting part are connected by snap-fit ​​or threaded connection to form a detachable connection. After the housing 5 is connected to the connecting section, a second antifreeze chamber is formed. The antifreeze component for the faucet is set in the second antifreeze chamber, and the drain outlet, metal spring 401, and lever assembly are all connected to the housing 5.

[0033] All the undisclosed matters mentioned above can be directly implemented using existing technologies, and therefore will not be elaborated upon here. The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several similar modifications and improvements without departing from the inventive concept of the present invention, and these should also be considered within the scope of protection of the present invention.
