Description

Technical Field

[0001] The present invention relates to the technical field of sanitary faucets, and more particularly, to a two-in-one kitchen water purification faucet. Background Art

[0002] With the improvement of living standards, more and more families install water purifiers. However, purified water requires a separate faucet and sink hole position. Many early houses did not reserve installation positions. Therefore, the demand for two-in-one kitchen water purification faucets is increasing. Our structure uses plastic parts for water passage and a metal shell, which has a low cost. Moreover, the purified water does not pass through metal electroplated parts, preventing problems such as excessive nickel metal in the electroplated parts. However, in existing two-in-one kitchen water purification faucets, such as a dual-waterway kitchen faucet with the publication number CN203115187U, since there are two valve cores, and the valve cores are sealed through the bottom end faces, when installing the two valve cores, they need to be pressed against each other from both sides, resulting in the problem of the pressing forces opposing each other on both sides, which will affect the long-term sealing effect and is prone to leakage. Summary of the Invention

[0003] The present invention discloses a two-in-one kitchen water purification faucet with a simple structure and convenient operation, aiming to improve the problem of easy leakage caused by the opposing forces on both sides of the dual-waterway valve cores in the prior art.

[0004] The present invention adopts the following solution: A two-in-one kitchen water purification faucet includes a water spout, a body, and a valve core seat disposed in the body. An opposingly installed mixing valve core and a purified water valve core are provided on the valve core seat. A mixing water channel and a purified water channel that are respectively communicated with the mixing valve core and the purified water valve core are provided in the water spout. It further includes: a adapter. Wherein, the adapter is installed on the valve core seat and forms a radial seal in the valve core seat; the purified water valve core is installed on the adapter.

[0005] Further, the bottom end face of the mixing valve core forms an end face seal in the valve core seat.

[0006] Further, the purified water valve core forms an end face seal in the adapter.

[0007] Further, a purified water handle is connected to the purified water valve core. The purified water handle is adapted to be installed on the body, and a step block is provided on the end face where it is connected to the body. A limit block for restricting the rotation amplitude of the step block is provided on the body.

[0008] Further, a hanging platform is provided on the adapter for positioning with the body, and it is locked on the body through a gland.

[0009] Further, a first positioning plane is provided on the inner side of the main body close to the water purification valve core, and the valve core seat is provided with a second positioning plane that cooperates with the positioning plane.

[0010] Further, the valve core seat is provided with a cold water inlet hole inclined to the left and a mixed water outlet hole inclined to the right, and the mixed water outlet hole is adapted to connect to the mixed water channel.

[0011] Further, the cold water inlet hole is inclined 30° - 50° to the left, and the mixed water outlet hole is inclined 30° - 50° to the right.

[0012] Further, a first positioning reference plane is provided on the inner side of the main body close to the mixing valve core, and the valve core seat is provided with a second positioning reference plane that cooperates with the first positioning reference plane. A gland is fixedly provided at one end where the water purification valve core is provided, and the gland is adapted to press the valve core seat tightly in the main body, so that the first positioning reference plane and the second positioning reference plane are tightly fitted.

[0013] Further, a fixing seat is provided at the bottom of the main body, and the fixing seat is adapted to press the valve core seat tightly in the main body.

[0014] Beneficial effects:

[0015] In the present invention, by providing an adapter between the valve core seat and the water purification valve core, radial sealing is achieved between the adapter and the valve core seat, and end-face connection is achieved between the mixing valve core and the valve core seat. In this way, the problem of the two sides of the valve core seat being forced to oppose each other when the existing water purification valve core and mixing valve core are installed oppositely and both are end-face sealed can be effectively solved, preventing the influence on the long-term sealing effect when the water purification valve core and the mixing valve core oppose and are stressed. Therefore, radial sealing is adopted between the adapter and the valve core seat, and bottom surface sealing is adopted between the water purification valve core and the adapter. In this way, when installing the water purification valve core and the mixing valve core, they are independent of each other, and the service life and sealing effect of the two valve cores can be ensured to be better. In a further setting, the cold water inlet hole and the mixed water outlet hole of the valve core seat adopt the scheme of inclined holes in opposite directions, so that the water paths of the two valve cores do not interfere with each other.

Detailed implementation manners

[0027] Embodiment

[0028] Combined with Figures 1 to 10 As shown, this embodiment provides a two-in-one kitchen faucet for purified water, including a water nozzle 5, a body 1, and a valve core seat 2 arranged in the body 1. The valve core seat 2 is provided with a oppositely installed mixed valve core 4 and a purified water valve core 7. The water nozzle 5 is provided with a mixed water channel and a purified water channel respectively communicating with the mixed valve core 4 and the purified water valve core 7. It further includes: an adapter 8, wherein the adapter 8 is installed on the valve core seat 2 and forms a radial seal in the valve core seat 2; the purified water valve core 7 is installed on the adapter 8.

[0029] Continuing with reference to FIG. 2, in this embodiment, the kitchen water purification two-in-one faucet includes a water purification handle 6, a water purification valve core 7, a gland 10, an adapter 8, a main body 1, a valve core seat 2, a fixing seat 3, a mixing valve core 4, a base 101, a water nozzle 5, and a water purification water outlet pipe 9 disposed in the water nozzle 5, etc. Specifically, on the main body 1, a water purification valve core 7 installation hole and a mixing valve core 4 installation hole are oppositely provided, and a first positioning surface 11 is provided on the inner side of the main body 1 near the water purification valve core 7. A limiting block 13 is provided at the orifice of the water purification valve core 7 installation hole for restricting the rotation range of the water purification handle 6.

[0030] Continuing with reference to FIGS. 2 to Figure 7 shown, the valve core seat 2 is adapted to be inserted from the bottom of the main body 1, the upper part thereof is set as a plane, and a second positioning surface 21 for cooperating with the first positioning surface 11 is provided on its side. The valve core seat 2 is provided with an adapter 8 installation hole and a mixing valve core 4 installation hole corresponding to the water purification valve core 7 installation hole and the mixing valve core 4 installation hole. When the mixing valve core 4 is installed, the first positioning surface 11 of the main body 1 is used as the force-bearing reference for installation, so that the valve core seat 2 is tightly pressed against the first positioning surface 11. A water purification water inlet hole, a cold water inlet hole 23, a hot water inlet hole, a mixed water outlet hole 24, and an inlet and outlet water hole are provided on the valve core seat 2. Among them, the cold water inlet hole 23 is inclined at an angle of 30° to 50° to the left, and the mixed water outlet hole 24 is inclined at an angle of 30° to 50° to the right. Through this solution, the inlet and outlet water paths of the mixing valve core 4 and the water purification valve core 7 can be made non-interfering with each other, solving the problems that in the market, a split valve core seat 2 is used to realize the water path, the assembly is complex, and it is easy to leak water due to the superposition of multiple positioning references. A fixing seat 3 is provided at the bottom of the main body 1, and the fixing seat 3 is used to tightly press the valve core seat 2 in the main body 1.

[0031] The mixing valve core 4 is a commonly used existing hot and cold water mixing valve core, which is connected with a handle, and the bottom end surface is adapted to form an end face seal in the valve core seat 2. Leakage can be effectively prevented through the conventional end face seal form.

[0032] The adapter 8 is suitable for being installed into the body 1 through the installation hole of the water purification valve core 7, and is suitable for being fixed on the valve core seat 2. The adapter 8 can be set in the shape of a rotating body, and a hanging platform 81 is set on its side to be positioned with the body 1, and is locked on the body 1 through a pressure cover 10. The adapter 8 is provided with an installation cavity for installing the water purification valve core 7, and the water purification valve core 7 forms an end face seal in the installation cavity of the adapter 8. The adapter 8 is provided with a water inlet and a water outlet, which are matched and connected with the water inlet and water outlet of the water purification valve core 7 respectively, and the water outlet of the adapter 8 is connected to the purification water outlet pipe 9. The outer side edge of the adapter 8 is provided with a sealing ring 82 on the surface connected to the valve core seat 2, which is used to achieve radial sealing with the valve core seat 2. In this way, when locking the adapter 8, there is no need to use a large pressing force to make the adapter 8 form a seal in the valve core seat 2, and the pressing force on the valve core seat 2 can be small, which effectively solves the problem of the existing water purification valve core 7 and mixing valve core 4 being installed in opposition and the force on both sides of the valve core seat 2 generated when both are end-face sealed, and prevents the influence of the long-term sealing effect when the water purification valve core 7 and the mixing valve core 4 are subjected to the force against each other. Therefore, the adapter 8 is radially sealed with the valve core seat 2, and the water purification valve core 7 is sealed with the bottom surface of the adapter 8, so as to reduce the pressing force required for installing the water purification valve core 7. In this way, the water purification valve core 7 and the mixing valve core 4 will not interfere with each other when installed, which can ensure that the service life of the two valve cores is longer and the sealing effect is better.

[0033] The water purification valve core 7 is a prior art product, which is connected to a water purification handle 6, which is suitable for installation on the body 1, and a step block 61 is provided on the end surface connected to the body 1, and the step block 61 cooperates with a limit block 13 provided on the body 1, and the limit block 13 can limit the range of rotation of the step block 61, thereby limiting the rotation angle of the water purification handle 6. This setting can prevent the water purification valve core 7 from failing to meet the requirements due to a small torsion resistance, and can also prevent the water purification valve core 7 from being damaged and failing due to excessive operating force.

[0034] In some embodiments, the body 1 may be provided with a first positioning reference surface 12 on the inner side close to the mixing valve core 4, the valve core seat 2 may be provided with a second positioning reference surface 22 matching the first positioning reference surface 12, and a gland 10 may be fixedly provided from one end where the water purification valve core 7 is provided, and the gland 10 may be adapted to press the valve core seat 2 tightly against the body 1, so that the first positioning reference surface 12 and the second positioning reference surface 22 may be closely matched. Here, the valve core seat 2 and the body 1 are locked together by the gland 10, and the gland 10 may be glued and locked, so that when the water purification valve core 7 and the mixing valve core 4 are installed, they will not be affected by the locking force on each other, resulting in unstable quality.

[0035] Through the solution of the present invention, the problem of poor long-term sealing performance of the dual-purpose faucet can be effectively solved, and the service life can be improved.
