Description

Technical Field

[0001] This utility model belongs to the field of water valve technology, and in particular relates to a faucet structure. Background Technology

[0002] Currently, most faucets used in washbasins employ a faucet structure, which has several drawbacks: First, the side wall of the valve core seat is relatively thin. To ensure a tight seal between the valve core seat and the water outlet pipe, the side wall of the valve core seat must be made thicker, or a connector must be added to the valve core seat. This not only increases material consumption but also makes the product larger, affecting its aesthetics. Second, the fixing structure between the water outlet pipe and the water outlet channel of the faucet body is not secure, resulting in some noise during use. Third, there is no fixing structure between the valve core seat and the faucet body, making it difficult to align and insert the water outlet pipe during installation, leading to installation difficulties. Summary of the Invention

[0003] The purpose of this utility model is to provide a faucet structure that saves raw materials, is small in size, and has a good fixation between the valve core seat and the faucet body, as well as between the water outlet pipe and the water outlet channel of the faucet body.

[0004] The purpose of this utility model is to solve the following problem:

[0005] A faucet structure includes a vertical and hollow faucet body, a water outlet channel extending to one side from the middle of the faucet body and communicating with the hollow part of the faucet body, a partition inside the faucet body dividing the inner cavity of the faucet body into an upper cavity and a lower cavity, a valve core seat, a valve core, a pressure cap, a decorative cover and a handle connected sequentially from bottom to top in the upper cavity of the faucet body, an arc-shaped groove on the side wall of the valve core with a sealing ring and a fixing plate installed thereon, a water passage hole penetrating the side wall in the middle of the arc-shaped groove, a water outlet pipe in the water outlet channel, two or more guide vanes on the side wall of one end of the water outlet pipe, the water outlet pipe outside the guide vanes passing through the fixing plate and the sealing ring in sequence to seal the water outlet pipe to the arc-shaped groove on the valve core seat.

[0006] The two or more guide vanes are circumferentially spaced on the outer wall of the water outlet pipe.

[0021] A faucet structure includes a vertical and hollow faucet body 17, a water outlet channel 171 extending to one side from the middle of the faucet body 17 and communicating with the hollow portion of the faucet body 17, and a partition 173 disposed inside the faucet body 17 dividing the inner cavity of the faucet body 17 into an upper cavity 172 and a lower cavity 174. Within the upper cavity 172 of the faucet body 17, a valve core seat 16, a valve core 13, a pressure cap 12, a decorative cover 11, and a handle 10 are sequentially connected from bottom to top. A sealing ring 19 and a fixing piece 20 are installed on an arc-shaped groove 162 disposed on the side wall of the valve core seat 16. A water passage hole 161 penetrating the side wall is provided in the middle of the arc groove 162. A water outlet pipe 21 is provided in the water outlet channel 171. Two or more guide vanes 212 are provided on the side wall of one end of the water outlet pipe 21. The water outlet pipe 21 outside the guide vanes 212 passes through the fixing plate 20 and the sealing ring 19 in sequence to seal the water outlet pipe 21 with the arc groove 162 on the valve core seat 16, so that the inner cavity of the water outlet pipe 21 is connected with the water passage hole 161. The fixing plate 20 can be fixed to the valve core 13 by ultrasonic welding, glue fixation, or snap-fit ​​structure.

[0022] The two or more guide vanes 212 are circumferentially spaced on the outer wall of the water outlet pipe 21.

[0023] The arc-shaped groove 162 is a two-stage stepped groove. The two-stage stepped groove is set at the same depth along the arc-shaped outer wall of the valve core seat 16. The sealing ring 19 is installed in the inner stepped groove, and the fixing piece 20 is installed in the outer stepped groove.

[0024] The fixing piece 20 is an arc-shaped piece that matches and is installed with the outer stepped groove. Both ends of the arc-shaped piece are formed with columns 201 facing the valve core 13. The end face of the column 201 is provided with a positioning protrusion 202. The valve core 13 is provided with a strip groove 163 corresponding to the column 201 and the positioning protrusion 202.

[0025] The other end of the water outlet pipe 21 is provided with an annular step 211 that is snapped into the annular groove at the outlet of the water outlet channel 171. A gasket 22 and an aerator 23 are sequentially provided outside the annular step 211. The aerator 23 is screwed onto the inner wall at the outlet of the water outlet channel 171 to fix the water outlet pipe 21 to the water outlet channel 171.

[0026] The sealing ring 19 is a Y-shaped ring with a trapezoidal cross-section 191. An annular rectangular groove 192 is provided on one end face of the trapezoidal cross-section 191.

[0027] The lower end face of the valve core 13 is provided with a vertical positioning post 164 and a threaded groove 166. The partition plate 173 is provided with positioning holes, through holes and water inlet pipe mounting holes that match the positioning post 164 and the threaded groove 166. After the valve core 13 positioning post 164 is inserted into the positioning hole, a screw 18 is passed through the through hole on the partition plate 173 and screwed into the threaded groove 166, thereby fixing the valve core 13 and the faucet body 17 together.

[0028] The outstanding advantages of this utility model compared to the prior art are:

[0029] 1. In this utility model, a fixing plate 20 is used to fix the sealing ring 19 in the arc groove 162 of the valve core seat 16 for sealing. The water outlet pipe 21 is inserted into the valve core seat 16 from the water outlet of the water outlet channel 171 and cooperates with the sealing ring 19 for sealing. The Y-shaped sealing ring has good sealing performance.

[0030] 2. This utility model designs the sealing ring 19 on the outer wall of the valve core seat 16 and fixes it with a fixing plate, which effectively solves the problem of the thickness of the side wall of the valve core seat 16 or the need to add a joint for sealing. At the same time, it can better connect with the water outlet pipe.

[0031] 3. The installation of this utility model is simpler, and the sealing structure is more reasonable. A guide vane 212 is provided at the front of the water outlet pipe to guide the water outlet pipe 21 to be inserted along the axis of the water outlet channel 171, which facilitates better insertion.

[0032] 4. The outlet end of the water pipe 21 of this utility model is provided with two annular steps 211, which makes the water outlet pipe 21 fixed and easy to install and remove. There are steps in front of the water outlet, and the inner annular step 211 is designed to fit and lock into the inside of the water outlet channel 171, so that the water outlet pipe will not swing back and forth or left and right, and it is better to fix and seal with the valve core seat, aerator and other accessories.

[0033] 5. The bottom of the valve core seat 16 of this utility model is fixed to the partition plate 173 of the faucet body 17 by screws 18, so that the valve core seat 16 and the water outlet pipe 21 are integrated. After the water outlet pipe and the valve core seat 16 are inserted, they are not easy to loosen, which facilitates installation and later maintenance, and the product structure is more reasonable.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make simple substitutions or modifications to the technical solutions or technical features described in the foregoing embodiments, and these simple substitutions or modifications do not cause the essence of the corresponding technical solutions to deviate from the spirit and substance of the technical solutions of the embodiments of this utility model, and are still within the protection scope of this utility model.
