Description

Technical Field

[0001] The utility model relates to the field of sanitary faucets, and particularly to a leak-proof welded faucet. Background Art

[0002] In order to achieve multi-angle water outlet for the existing sink faucets, the water outlet pipe and the faucet body are usually connected by a connecting piece (such as the connecting piece disclosed in patent CN215568617U). The outer wall of the upper part of the connecting piece is fixedly connected to the water outlet pipe, and the lower end is fixedly connected to the faucet body by a thread. The lower end of the connecting piece and the faucet body are sealed by a sealing ring. Because users often swing the water outlet pipe during use, the connection part between the connecting piece and the main body is prone to deformation and leakage, and the deformation and aging of the sealing ring are also prone to leakage problems.

[0003] In view of this, the inventor of the present invention has conducted in-depth research on the above defects in the prior art, and thus this case has arisen. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a leak-proof welded faucet, which has the advantages of good sealing performance and avoiding water leakage.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A leak-proof welded faucet, which includes a faucet body, a connecting piece, and a water outlet pipe; the connecting piece includes an outer cylinder and an inner cylinder, and the inner cylinder is rotatably inserted into the outer cylinder; the outer cylinder is fixedly inserted at the lower end of the water outlet pipe; an installation seat is formed at the lower end of the inner cylinder, and the lower end of the installation seat is fixedly sealed and welded to the upper end of the faucet body.

[0007] Further, a sinking groove is formed at the upper part of the installation seat, a feel ring is formed at the lower end of the outer cylinder, the feel ring is embedded in the sinking groove, the upper end of the feel ring does not protrude above the upper end of the sinking groove, and the upper end of the feel ring abuts against the lower end of the water outlet pipe.

[0008] Further, a water inlet channel, a water outlet cavity, and a valve core cavity for installing a valve core are formed in the faucet body. The water inlet channel is communicated with the valve core cavity, and the valve core cavity is communicated with the water outlet cavity.

[0009] Further, a positioning ring is formed at the lower end of the installation seat, and the positioning ring is inserted into the inner wall of the upper end of the water outlet cavity.

[0010] Further, the water inlet channel includes a cold water channel and a hot water channel, the cold water channel and the hot water channel are respectively communicated with the valve core cavity, and the valve core cavity and the water outlet cavity are communicated through a water outlet channel.

[0011] Further, the feel ring is made of plastic material.

[0012] After adopting the above structure, a leak-proof welded faucet involved in the present utility model has at least the following beneficial effects:

[0013] First, the lower end of the connecting piece is directly sealed and welded to the upper end of the faucet body through the mounting seat, thus greatly improving the connection strength and sealing performance between the faucet body and the connecting piece and avoiding the problem of water leakage.

[0014] Second, the feel ring is embedded and installed in the sink, and then its upper part abuts against the lower end of the water outlet pipe. In this way, the feel ring will be completely shielded from the appearance, which makes the faucet body and the water outlet pipe have better integrity. At the same time, dust and dirt are not easily introduced into the gap of the feel ring, making the water outlet pipe rotate more smoothly.

[0015] Third, by setting the positioning ring, the docking of the mounting seat and the faucet body is more convenient, facilitating the welding operation during processing and also enhancing the connection strength between the mounting seat and the faucet body.

[0016] Compared with the prior art, the leak-proof welded faucet of the present utility model fixes the faucet body and the connecting piece by welding, greatly improving the connection strength and sealing performance and avoiding the problem of water leakage of the faucet.

[0027] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0028] As Figures 1 to 4 shown, it is a leak-proof welded faucet related to the present invention, including a faucet body 1, a connector 2, and a water outlet pipe 3; the connector 2 includes an outer cylinder 21 and an inner cylinder 22, and the inner cylinder 22 is rotatably inserted into the outer cylinder 21; the outer cylinder 21 is fixedly inserted at the lower end of the water outlet pipe 3; an installation seat 23 is formed at the lower end of the inner cylinder 22, and the lower end of the installation seat 23 and the upper end of the faucet body 1 are hermetically welded and fixed. The lower end of the connector 2 is directly hermetically welded to the upper end of the faucet body 1 through the installation seat 23, thus greatly improving the connection strength and sealing performance between the faucet body 1 and the connector 2 and avoiding the problem of water leakage. And compared with the traditional threaded connection method, welding does not require threading processing, reducing the processing cost of the product and having better economy.

[0029] Preferably, a sink 24 is formed in the upper part of the installation seat 23, a feel ring 25 is formed at the lower end of the outer cylinder 21, the feel ring 25 is embedded in the sink 24, the upper end of the feel ring 25 does not protrude above the upper end of the sink 24, and the upper end of the feel ring 25 abuts against the lower end of the water outlet pipe 3. The feel ring 25 is embedded and installed in the sink 24 and then its upper end abuts against the lower end of the water outlet pipe 3, so that the feel ring 25 will be completely covered from the appearance, which makes the faucet body 1 and the water outlet pipe 3 have better integrity. At the same time, dust and dirt are not easily introduced into the gap of the feel ring 25, making the water outlet pipe 3 rotate more smoothly. Preferably, the feel ring 25 is made of plastic material.

[0030] Preferably, a water inlet channel 11, a water outlet cavity 12, and a valve core cavity 13 for installing a valve core are formed in the faucet body 1. The water inlet channel 11 is communicated with the valve core cavity 13, and the valve core cavity 13 is communicated with the water outlet cavity 12. Water flows into the faucet body 1 from the water inlet channel 11, then flows to the valve core cavity 13, is controlled by the valve core in the valve core cavity 13 and then flows to the water outlet cavity 12, and finally flows out from the water outlet pipe 3.

[0031] Preferably, a positioning ring 26 is formed at the lower end of the installation seat 23, and the positioning ring 26 is inserted into the inner wall of the upper end of the water outlet cavity 12. By providing the positioning ring 26, the docking of the installation seat 23 and the faucet body 1 is more convenient, the welding operation during processing is facilitated, and the connection strength between the installation seat 23 and the faucet body 1 is also improved.

[0032] Preferably, as Figure 4 shown, the water inlet passage 11 includes a cold water passage 111 and a hot water passage 112. The cold water passage 111 and the hot water passage 112 are respectively communicated with the valve core cavity 13, and the valve core cavity 13 and the water outlet cavity 12 are communicated through a water outlet passage 14. In this way, cold water and hot water can enter the valve core cavity 13, and after being mixed and controlled by the valve core, they flow out from the water outlet cavity 12.

[0033] Compared with the prior art, the leak-proof welded faucet of the present invention fixes the faucet main body 1 and the connecting member 2 by welding, greatly improving the connection strength and sealing performance, and avoiding the problem of water leakage of the faucet.

[0034] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
