Description

Technical Field

[0001] This invention relates to the field of concealed faucet technology, specifically to a faucet valve seat. Background Technology

[0002] Embedding the faucet within the wall, with only the operating handle protruding from the wall surface, results in an aesthetically pleasing design and saves indoor space. Existing concealed faucets, such as CN202531902U – a wall-mounted faucet pre-embedded integrated module – connect the flow channel by locking the valve seat to a pre-embedded box within the wall. However, the resistance between the sealing surfaces of the valve seat and the pre-embedded box comes entirely from the tightening force of the bolts, leading to poor sealing between the pre-embedded box and the valve seat.

[0003] In view of this, the applicant conducted in-depth research on the aforementioned deficiencies in the prior art, which led to this case. Summary of the Invention

[0004] The main objective of this invention is to provide a faucet valve seat that improves the sealing effect between the valve seat and the embedded box.

[0005] To achieve the above objectives, the solution of the present invention is: A faucet valve seat includes a first valve seat body and a second valve seat body for mounting different functional valve cores. A connecting channel is provided between the first valve seat body and the second valve seat body, the connecting channel connecting the water outlet end of the first valve seat body and the water inlet end of the second valve seat body. A water inlet hole is formed on the first valve seat body, and a water outlet hole is formed on the second valve seat body. Abutting sealing surface is formed on the first valve seat body and the second valve seat body, corresponding one-to-one with the water inlet hole and the water outlet hole. The water inlet hole and the water outlet hole pass through the abutting sealing surface, and the abutting sealing surface is inclined to the installation direction of the valve seat.

[0006] Furthermore, the water inlet includes two water inlets for hot water and cold water, respectively. The hot water inlet and the cold water inlet are located on the sealing surface of a first valve seat body, and the sealing surfaces of the cold water inlet and the cold water inlet are located on opposite sides of the first valve seat body.

[0007] Furthermore, the water outlet includes a first water outlet, a second water outlet, and a third water outlet, which are respectively located on the top sealing surface of a second valve seat body; the top sealing surfaces where the first water outlet and the third water outlet are located are respectively located on opposite sides of the second valve seat body, and the top sealing surface where the second water outlet is located is located on the side of the top sealing surfaces where the first water outlet and the third water outlet are located and is connected to them.

[0008] Furthermore, the normal direction of the abutment sealing surface is set at an acute angle to the installation direction of the valve seat, and the acute angle formed by the normal direction of the abutment sealing surface and the installation direction of the valve seat is α, 45°≤α<90°; a sealing ring is provided on each abutment sealing surface around the water inlet or water outlet.

[0009] Furthermore, the first valve seat body and the second valve seat body are made of PPR, copper alloy or stainless steel.

[0010] Furthermore, both the first valve seat body and the second valve seat body have a retainer extending along the valve seat installation direction.

[0011] Furthermore, the acute angle α formed by the normal direction of the abutting sealing surface and the installation direction of the valve seat is 80°.

[0012] Furthermore, the first valve seat body and the second valve seat body are integrally formed, and the connecting channel is integrally formed between the second valve seat body and the second valve seat body.

[0013] Furthermore, the first valve seat body and the second valve seat body are integrally formed from metal.

[0014] Furthermore, the first valve seat body and the second valve seat body are separately disposed, and a connecting pipe is connected between the second valve seat body and the second valve seat body, and the connecting channel is formed in the connecting pipe.

[0015] Furthermore, the two ends of the connecting pipe are respectively inserted and connected to the first valve seat body and the second valve seat body.

[0016] Furthermore, the first valve seat body and the second valve seat body are also provided with mounting plates for locking the first valve seat body and the second valve seat body onto the pre-embedded box; the mounting plate is integrally connected to the first valve seat body and the second valve seat body, or the mounting plate is separately connected to the first valve seat body and the second valve seat body, and the mounting plate abuts against the abutting protrusion of the first valve seat body and the second valve seat body.

[0017] With the above structure, the faucet valve seat of the present invention has at least the following beneficial effects: 1. The water inlet hole on the first valve seat body and the water outlet hole on the second valve seat body are connected to the functional valve cores on the first and second valve seat bodies respectively through the flow channels inside the valve seat. In use, the abutting sealing surface is connected to the abutting sealing end face of the flow channel on the embedded box. Since the abutting sealing surface is inclined to the installation direction of the valve seat, that is, the abutting sealing surface is not perpendicular to the installation direction of the valve seat, the magnitude of the abutting force on the abutting sealing surface will be greater than the locking force used to lock the valve seat, thereby better sealing the abutting sealing surface around the water inlet hole or the water outlet hole and improving the sealing effect.

[0018] Second, the reaction forces on the top sealing surfaces located on opposite sides of the valve seat body cancel each other out in the component of force perpendicular to the valve seat installation direction. That is, the valve seat can be very stable even when the clamping force on the top sealing surface is large, and the clamping force on the top sealing surface does not completely depend on the locking force of the valve seat.

[0019] Third, the first valve seat body and the second valve seat body are formed separately, which allows the first valve seat body and the second valve seat body to be processed independently, and also reduces the material required for the valve seat body. The first valve seat body and the second valve seat body are then connected by a connecting pipe, which greatly improves the yield of the faucet valve seat and reduces the production cost.

[0020] Fourth, the mounting plate is separately set from the first valve seat body and the second valve seat body. In this way, the mounting plate can be processed with different materials from the first valve seat body and the second valve seat body. For example, the valve seat body is made of copper and the mounting plate is made of stainless steel, which reduces the overall cost.

[0021] Compared with the prior art, the present invention adopts an inclined top sealing surface, which makes the sealing effect of the top sealing surface around the water inlet and water outlet through holes and the top sealing end face on the pre-embedded box better. Attached Figure Description

Detailed Implementation

[0030] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0031] like Figures 1 to 7 As shown, this invention relates to a faucet valve seat, comprising a first valve seat body 1 and a second valve seat body 2 for mounting different functional valve cores. A connecting channel is provided between the first valve seat body 1 and the second valve seat body 2, the connecting channel connecting the water outlet end of the first valve seat body 1 and the water inlet end of the second valve seat body 2. A water inlet hole is formed on the first valve seat body 1, and a water outlet hole is formed on the second valve seat body 2. Abutting sealing surface 3 is formed on the first valve seat body 1 and the second valve seat body 2, corresponding one-to-one with the water inlet hole and the water outlet hole. The water inlet hole and the water outlet hole pass through the abutting sealing surface 3, and the abutting sealing surface 3 is inclined to the installation direction of the valve seat.

[0032] Thus, the present invention relates to a faucet valve seat in which the water inlet hole on the first valve seat body 1 and the water outlet hole on the second valve seat body 2 are connected to the functional valve cores on the first valve seat body 1 and the second valve seat body 2 respectively through the flow channel inside the valve seat. In use, the abutting sealing surface 3 is connected to the abutting sealing end face of the flow channel on the pre-embedded box 300. Since the abutting sealing surface 3 is inclined to the installation direction of the valve seat, that is, the abutting sealing surface 3 is not perpendicular to the installation direction of the valve seat, the magnitude of the abutting force on the abutting sealing surface 3 will be greater than the locking force used to lock the valve seat, thereby better sealing the abutting sealing surface 3 around the water inlet hole or the water outlet hole and improving the sealing effect.

[0033] Preferably, the water inlet orifice includes two inlet holes, a hot water inlet hole 11 and a cold water inlet hole 12, for hot water and cold water respectively. The hot water inlet hole 11 and the cold water inlet hole 12 are each located on a sealing surface 3 on a first valve seat body 1. The sealing surfaces 3 containing the cold water inlet hole 12 are located on opposite sides of the first valve seat body 1. The hot and cold water flowing through the hot water inlet hole 11 and the cold water inlet hole 12 flow to the mixing valve core 100 on the first valve seat body 1. The mixed water then flows through a connecting channel to other functional valve cores on the second valve core body, such as the water distribution valve core 200.

[0034] Preferably, the water outlet includes a first water outlet 21, a second water outlet 22, and a third water outlet 23. The first water outlet 21, the second water outlet 22, and the third water outlet 23 are respectively located on the abutting sealing surface 3 of a second valve seat body 2. The abutting sealing surfaces 3 where the first water outlet 21 and the third water outlet 23 are located are respectively located on opposite sides of the second valve seat body 2. The abutting sealing surface 3 where the second water outlet 22 is located is located on the side of the abutting sealing surfaces 3 where the first water outlet 21 and the third water outlet 23 are located and is connected to them. The water distribution valve core 200 selects to discharge water through the first water outlet 21, the second water outlet 22, or the third water outlet 23.

[0035] The reaction forces on the abutting sealing surfaces 3 located on opposite sides of the valve seat body cancel each other out in the component of force perpendicular to the valve seat installation direction. That is, the valve seat can be very stable even when the abutting force on the abutting sealing surface 3 is large, and the abutting force on the abutting sealing surface 3 does not completely depend on the locking force of the valve seat.

[0036] Preferably, the normal direction of the abutment sealing surface 3 is set at an acute angle to the installation direction of the valve seat, and the acute angle between the normal direction of the abutment sealing surface 3 and the installation direction of the valve seat is α, where 45°≤α<90°; each abutment sealing surface 3 is provided with a sealing ring 31 located around the water inlet or water outlet through hole. Furthermore, the acute angle α between the normal direction of the abutment sealing surface 3 and the installation direction of the valve seat is 80°. Thus, when the valve seat is installed along the installation direction from the outside to the inside, as the locking mechanism between the valve seat and the embedded box 300 is tightened, the abutment force between the sealing end face of the abutment sealing surface 3 and the embedded box 300 increases, resulting in a more complete seal. By providing the sealing ring 31, the sealing performance is further improved. When the abutment sealing surface 3 is abutted, the sealing ring 31 deforms, thereby fitting well with the abutment sealing surface 3 and improving the sealing effect. Preferably, the first valve seat body 1 and the second valve seat body 2 are made of PPR, copper alloy, or stainless steel.

[0037] Preferably, both the first valve seat body and the second valve seat body 2 have a retaining seat 61 extending along the valve seat installation direction. Thus, during valve seat installation, the abutting sealing end face on the embedded box 300 that mates with the abutting sealing surface 3 is located between the abutting sealing surface 3 and the retaining seat 61, allowing the abutting sealing surface 3 to provide a tighter abutment. The retaining seat 61 may be formed on the edge of the mounting plate 6 and extend perpendicularly to the mounting plate 6.

[0038] Preferably, the first valve seat body 1 and the second valve seat body 2 are integrally formed, and the connecting channel is integrally formed between the second valve seat body 2 and the second valve seat body 2. Furthermore, the first valve seat body 1 and the second valve seat body 2 are integrally formed from metal. The connection between the integrally formed first valve seat body 1 and the second valve seat body 2 is more stable.

[0039] Preferably, the first valve seat body 1 and the second valve seat body 2 can also be separately configured, with a connecting pipe 5 connecting the two valve seat bodies 2, and the connecting channel formed within the connecting pipe 5. The separate molding of the first valve seat body 1 and the second valve seat body 2 allows for individual processing of both, reducing the material required for the valve seat bodies. Connecting the first valve seat body 1 and the second valve seat body 2 via the connecting pipe 5 significantly improves the yield rate of the faucet valve seat and reduces production costs. Preferably, both ends of the connecting pipe 5 are respectively inserted into the first valve seat body 1 and the second valve seat body 2. The connecting pipe 5 connects the water outlet end of the first valve seat body 1 to the water inlet end of the second valve seat body 2.

[0040] Preferably, the first valve seat body 1 and the second valve seat body 2 are further provided with mounting plates 6 for locking the first valve seat body 1 and the second valve seat body 2 onto the embedded box 300; the mounting plate 6 is integrally connected to the first valve seat body 1 and the second valve seat body 2, or the mounting plate 6 is separately connected to the first valve seat body 1 and the second valve seat body 2, and the mounting plate 6 abuts against the abutting boss 4 of the first valve seat body 1 and the second valve seat body 2. The mounting plate 6 is separately configured from the first valve seat body 1 and the second valve seat body 2, so that the mounting plate 6 can be processed from different materials than the first valve seat body 1 and the second valve seat body 2, such as the valve seat body being made of copper, and the mounting plate 6 being made of stainless steel or PPR, thus reducing the overall cost. Of course, the mounting plate 6 can also be made of copper alloy. The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
