Description

A new type of valve core design faucet Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a novel valve core design faucet. Background Technology

[0002] As a crucial and widely used device, the faucet's core function lies in the precise and flexible control of water flow. It is typically installed at the end of the water supply pipe and is an indispensable water control component in areas such as the kitchen, bathroom, and balcony of a home. Whether for daily handwashing, washing vegetables and rice, cleaning dishes, or washing and drying clothes, the faucet plays an irreplaceable role in water usage. Technical issues

[0003] Currently, ceramic valve cores on the market are all custom-designed for specific applications, with the valve core and valve core seat integrated into a single unit that cannot be separated. Because the valve core is a consumable part with a limited lifespan, it needs to be replaced periodically during daily use. However, the valve core seat is not a consumable part and has a long lifespan, so it does not require regular replacement. Due to the existing integrated design and use of the valve core and valve core seat, the valve core seat is replaced along with the valve core when it is replaced, thus increasing unnecessary replacement costs. In older faucets, there is only a valve core without a valve core seat. Although this does not incur unnecessary costs when replacing it, the internal design of such faucets is not airtight enough, leading to water retention inside the faucet during use, which is not energy-efficient or environmentally friendly. Therefore, a new type of valve core design faucet is proposed to solve the above problems. Technical solutions

[0004] To overcome the above shortcomings, this utility model provides a new type of valve core design faucet, which aims to improve the problem that the valve core seat and valve core are connected as a single piece in the prior art and are difficult to disassemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel valve core design faucet, including a base, a handle rotatably connected to the top of the base, a connecting plate threadedly connected to the top of the base, a valve core detachably installed on the inner wall of the base, and a positioning component provided at the bottom of the valve core;

[0006] The positioning component includes a limiting post, a valve core seat is fixedly connected to the bottom end of the valve core, a connection hole is opened at the top end of the valve core seat, a water outlet pipe is inserted into the right end of the valve core seat, a plug is provided on the inner wall of the left end of the valve core seat, and an adjustment component is provided on the inner wall of the right end of the base.

[0007] As a further description of the above technical solution:

[0008] The outer wall of the valve core contacts the inner side wall of the connecting plate, and the top end of the limiting post is fixedly connected to the bottom end of the valve core.

[0009] As a further description of the above technical solution:

[0010] The bottom end of the limiting post is inserted into the inner wall of the connecting hole.

[0011] As a further description of the above technical solution:

[0012] A sealing gasket is provided between the valve core seat and the water outlet pipe.

[0013] As a further description of the above technical solution:

[0014] A circular ring is provided between the plug and the valve core seat.

[0015] As a further description of the above technical solution:

[0016] The adjustment assembly includes a support rod, the top end of which is fixedly connected to the inner wall of the right end of the base, and a fixing plate is fixedly connected to the outer arc surface of the bottom end of the support rod. A rotating plate is rotatably connected to the bottom end of the base, and a positioning rod is elastically connected to the inner wall of the rotating plate via a connecting spring.

[0017] As a further description of the above technical solution:

[0018] One end of the connecting spring is fixedly connected to the outer wall of the positioning rod, and the other end of the connecting spring is fixedly connected to the inner wall of the rotating plate. The outer wall of the positioning rod is slidably connected to the rotating plate, and the spherical surface of the rotating plate is inserted into the inner wall of the right end of the base.

[0019] As a further description of the above technical solution:

[0020] The top of the fixing plate has a bevel. Beneficial effects

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting the connection hole, the limiting post and the valve core and other structures to cooperate with each other, the valve core and the valve core seat are produced separately and assembled for use. When using, it will not cause water to remain inside the faucet due to the lack of a valve core seat, as is the case with the old-fashioned faucet design. It also solves the drawbacks of the one-piece valve core design. There is no need to replace the valve core seat when replacing the valve core, which greatly reduces the cost of using the faucet.

[0023] 2. In this utility model, by setting up a rotating plate, a fixed plate and a positioning rod and other structures to cooperate with each other, when the water flow is too large, the rotating plate can be rotated to adjust the water flow, thereby avoiding the user's cuffs from getting wet due to excessive water flow, and the adjustment is more convenient.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Referring to Figures 1-3, one embodiment of this utility model is provided: a novel valve core design faucet, including a base 1, with a handle 2 rotatably connected to the top of the base 1. The base 1 can be installed in a corresponding position, and water can be dispensed through the handle 2. This is prior art and will not be explained in detail here. A connecting plate 3 is threadedly connected to the top of the base 1, and the two are threadedly connected to achieve a fixing effect. The connecting plate 3 can be disassembled, and the disassembly operation is relatively simple and convenient. A valve core 4 is detachably installed on the inner wall of the base 1. The valve core 4 can be disassembled for easy replacement. A positioning component is provided at the bottom of the valve core 4; the positioning component can fix the valve core 4 in place.

[0033] The positioning component includes two sets of limiting posts 11 to facilitate the installation of the valve core 4. The bottom end of the valve core 4 is fixedly connected to the valve core seat 9, and the two are detachable to facilitate the use of the faucet. The top end of the valve core seat 9 has connecting holes 10, and the number of connecting holes 10 corresponds to the number of limiting posts 11. The right end of the valve core seat 9 is connected to a water outlet pipe 6, which allows water to flow out. The left end of the valve core seat 9 has a plug 7 on its inner wall, which reduces the amount of impurities entering the valve core seat 9. The right end of the base 1 has an adjustment component on its inner wall, which allows the water flow to be adjusted.

[0034] Referring to Figures 1-3, the outer wall of the valve core 4 contacts the inner side wall of the connecting plate 3. The contact between the two fixes the valve core 4, preventing it from moving upward. When the connecting plate 3 moves downward, the valve core 4 is squeezed and becomes more stable. The top of the limiting post 11 is fixedly connected to the bottom of the valve core 4. The two move in the same direction and are easy to install and fix. The bottom of the limiting post 11 is inserted into the inner wall of the connecting hole 10. The two are inserted to achieve the purpose of positioning and fixing. A sealing gasket 5 is provided between the valve core seat 9 and the water outlet pipe 6. The sealing gasket 5 can seal the water outlet pipe 6. A circular ring 8 is provided between the plug 7 and the valve core seat 9. The circular ring 8 is made of rubber and can provide a sealing effect.

[0035] Referring to Figures 3-5, the adjustment assembly includes a support rod 12. The top end of the support rod 12 is fixedly connected to the inner wall of the right end of the base 1. The inner wall of the right end of the base 1 can support the support rod 12. A fixing plate 13 is fixedly connected to the outer arc surface of the bottom end of the support rod 12. A rotating plate 14 is rotatably connected to the bottom end of the base 1. Both the fixing plate 13 and the rotating plate 14 are semi-circular. A positioning rod 15 is elastically connected to the inner wall of the rotating plate 14 through a connecting spring 16. The end of the positioning rod 15 away from the support rod 12 is spherical.

[0036] Referring to Figures 3-5, one end of the connecting spring 16 is fixedly connected to the outer wall of the positioning rod 15, and the other end of the connecting spring 16 is fixedly connected to the inner wall of the rotating plate 14. The outer wall of the positioning rod 15 is slidably connected to the rotating plate 14. The elasticity of the connecting spring 16 enables the positioning rod 15 to have reset and limit functions. The spherical surface of the rotating plate 14 is inserted into the inner wall of the right end of the base 1. When the rotating plate 14 is not rotated manually, the rotating plate 14 is in a fixed state, and the spherical surface does not affect the rotation of the rotating plate 14. The top of the fixed plate 13 has an inclined surface, which allows water to be discharged from the top of the fixed plate 13.

[0037] Working principle: When the operator needs to disassemble and replace the valve core 4, first rotate the connecting plate 3 to release the threaded connection between the connecting plate 3 and the top of the base 1. After release, the valve core 4 is in an active state. Then, the operator can move the valve core 4 upward to release the insertion and positioning of the valve core 4 and the valve core seat 9. After removal and replacement, install the new valve core 4 on the top of the valve core seat 9, so that the bottom limiting post 11 of the new valve core 4 is inserted and positioned with the connecting hole 10 of the valve core seat 9. Then, screw the connecting plate 3 to move the connecting plate 3 downward to contact and squeeze the top of the valve core 4, thereby preventing the valve core 4 from moving vertically. The operation is simple and convenient.

[0038] When it is necessary to adjust the overall water flow of the faucet, the rotating plate 14 can be rotated so that the positioning rod 15 on the inner wall of the rotating plate 14 is pressed by the inner wall on the right side of the base 1, thereby locking the interior of the rotating plate 14. At this time, the opening between the rotating plate 14 and the fixed plate 13 will change, thereby adjusting the water flow and preventing the water from flowing too much and splashing onto the user's cuffs.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
