Description

With pollution-free water quality tubular valve core faucet

This work is about a faucet structure, especially a tubular valve core faucet with pollution-free water quality.

With the improvement of living standards, people pay more and more attention to health, and the cleanliness of drinking water has become an important issue. In order to prevent the excessive content of heavy metals in drinking water, most traditional faucets use copper or stainless steel materials to ensure lead-free. However, the cost of copper and stainless steel is relatively high, and the production process is relatively cumbersome, which affects the market competitiveness of the products. Therefore, basin faucets on the market usually adopt alloy one-piece forming technology. The lead element in the alloy will oxidize when it comes into contact with air to form a protective film, but the action of water will cause this protective film to fall off, resulting in the precipitation of lead elements, so that the lead content of the water flowing through these faucets exceeds the standard, resulting in potential toxicity problems. To solve this problem, faucets with pollution-free water quality tubular valve cores began to appear on the market.

For example, the Chinese utility model patent application number 202221691244.5 (publication number CN217842778A) "Structurally improved lead-free faucet" discloses such a faucet structure, which includes an outer shell, a valve core seat, a valve core body, a water outlet hose and a handle. The outer shell has a shell body and an extension rod, and the extension rod is extended from the shell body. The top of the body extends horizontally outward and is provided with a cavity. The valve core seat is accommodated in the shell body from top to bottom, and the valve core body is placed in the cavity of the valve core seat. The water outlet hose is installed in the cavity, one end of which is connected to the water outlet channel and the other end extends to the end of the cavity. The handle is provided above the valve core body and is used to control the valve rod action of the valve core body.

However, since the valve core seat is accommodated in the shell body from top to bottom, a water outlet channel is provided on the side of the valve core seat, and the water outlet hose is installed in the cavity of the extension rod, with one end plugged in and connected to the water outlet channel, and the other end extending to the end of the cavity. This design requires the plug-in connection between the water outlet hose and the valve core seat to be carried out inside the outer shell, and the softness of the water outlet hose itself makes it difficult to stably insert it into the water outlet channel of the valve core seat during installation, which not only increases the difficulty and cost of installation, but also may cause loosening and leakage between the water outlet hose and the water outlet channel during use, thereby increasing the risk of leakage and damage.

In view of the above shortcomings of the known faucet, the creator launched this creation after much discussion, sample testing and multiple revisions and improvements.

The invention discloses a water faucet with a non-polluting water quality tubular valve core, comprising: a faucet body, having a main body and an extension, a valve chamber is provided at the top end of the main body, the extension extends outward from one side of the main body, a cavity is provided inside the extension, and the cavity is connected to the valve chamber; a valve core seat is installed in the valve chamber of the main body, a clamping groove is provided on the top surface of the valve core seat, the clamping groove is aligned with and connected to the cavity of the extension, and two water inlet channels are provided on the valve core seat; a valve core is installed in the valve chamber of the main body , and assembled on the valve core seat, the bottom of the valve core is provided with two water inlets and a water outlet, the two water inlets are connected with the two water inlet channels of the valve core seat; and a water outlet hose is installed in the cavity, one end of the water outlet hose is provided with a connecting part, and the other end is provided with a water outlet, the connecting part is located on the clamping groove on the top surface of the valve core seat, and is clamped by the valve core seat and the valve core, and the end of the connecting part is provided with a connecting head, which is plugged and connected with the water outlet to form a positioning function, and the water outlet is located at one end of the cavity away from the main body.

The main purpose of this creation of a pollution-free tubular valve core faucet is that it not only does not come into contact with the metal faucet body during the water discharge process, but can effectively prevent water pollution and ensure the safety of water quality. In addition, the installation process of the water outlet hose is simple, the difficulty and cost of installation are reduced, and the stability after installation is good, which can reduce the possibility of loosening during use, thereby reducing the risk of leakage and damage.

The end of the connecting portion 41 is provided with a A connector 411 is plugged and connected with the water outlet 32 of the valve core 30, and is also fitted and fixed with the fixing portion 211 of the valve core seat 20 to form a stable positioning function. The water outlet 42 is located at one end of the cavity 121 away from the main body 11, and a bubbler 43 is installed at the end, and the bubbler 43 is connected to the water outlet 42.

The handle 50 is assembled with a locking piece 51 and a cap 52 on the upper end of the main body 11 and the valve core 30. The locking piece 51 is used to press and fix the valve core 30 and the valve core seat 20. The handle 50 is connected and linked with the valve rod 35 of the valve core 30.

In the assembly process of the invention, the valve core seat 20 is first installed in the valve chamber 111 of the main body 11, and then the water outlet hose 40 is installed in the cavity 121 of the extension portion 12, and the assembly portion 41 of the water outlet hose 40 is inserted into the clamping groove 21 on the top surface of the valve core seat 20, and the connector 411 of the water outlet hose 40 is inserted and fixed with the fixing portion 211 of the valve core seat 20, and then the valve core seat 20 is installed. The valve core 30 is installed in the valve chamber 111 of the main body 11 and assembled on the valve core seat 20, so that the assembly part 41 of the water outlet hose 40 is sandwiched between the clamping groove 21 of the valve core seat 20 and the matching groove 34 of the valve core 30, and the connector 411 of the water outlet hose 40 is plugged and connected with the water outlet 32 of the valve core 30, completing the installation of the valve core seat 20, the water outlet hose 40 and the valve core 30.

When in use, the handle 50 is turned to control the two water inlets 31 of the valve core 30 to open, so that water flows from the two water inlet pipes 24 through the two water inlet channels 23 of the valve core seat 20 and the two water inlets 31 of the valve core 30, enters the valve core 30 for cold and hot water mixing, and then flows from the water outlet 32 of the valve core 30 into the water outlet hose 40, is transmitted through the water outlet hose 40, and finally flows out from the bubbler 43. During this water outlet process, the water will not come into contact with the faucet body 10 at all.

Furthermore, as shown in the sixth and seventh figures, this is another embodiment of the present invention with a pollution-free water quality tubular valve core faucet. The difference between this other embodiment and the above embodiment is that it can use valve cores 30 of different specifications to adapt to various usage requirements, thereby not only improving the practicality of the faucet, but also providing a larger selection space, so that it can be adjusted according to actual needs, so as to achieve the best use effect, and the valve core seat 20 is provided with a plug hole 26, and the plug hole 26 is used for the assembly part 41 of the water outlet hose 40 to be inserted and assembled, so that the assembly part 41 of the water outlet hose 40 is connected with the water outlet 32 of the valve core 30.
