DETAILED DESCRIPTION

[0022] The present case will be further described in detail in combination with the drawings and specific embodiments.

[0023] The present case relates to a water inlet valve seat, which is installed in a faucet body and is connected with an outlet pipe also installed in the faucet body to form an internal water passage. As shown in Figures 1-3As shown, the water inlet valve seat comprises a valve seat body, the upper end side of the valve seat body is provided with a connecting surface 1, and the connecting surface 1 is provided with a waterway connecting end 2. When the water inlet valve seat is installed, the waterway connecting end 2 is coaxially connected with the water outlet pipe connecting end of the water outlet pipe. The water inlet valve seat of the present application is provided with a clamping portion 3 below the corresponding waterway connecting end 2 on the connecting surface 1.

[0024] As shown Figure 4 As shown is the installation application of the water inlet valve seat of the present application. The faucet body comprises a main body portion 101 and a water outlet portion 102 which are connected and communicated, the water inlet valve seat 200 of the present application is installed in the main body portion 101, and the water outlet pipe 300 is installed in the water outlet portion 102. The water outlet pipe 300 is provided with a water outlet pipe connecting end 301. When the water inlet valve seat 200 is assembled, the water outlet pipe 300 is clamped and fixed by the clamping portion 3, specifically, the water outlet pipe 300 is clamped and fixed on the outer circumferential surface corresponding to the water outlet pipe connecting end 301, so that the water outlet pipe 300 is clamped and fixed at the position where the water outlet pipe connecting end 301 and the water flow connecting end 2 are tightly connected. Figures 3-4 As shown in the schematic, the clamping portion 3 clamps and fixes the water outlet pipe 300 from below, and the corresponding position above the water outlet pipe 300 can be matched with related limiting structures to enhance the structural assembly stability, of course, the related limiting structures can also not be provided, and the clamping portion 3 can also achieve the function of clamping and fixing the water outlet pipe 300.

[0025] The present application clamps and fixes the water outlet pipe 300 from below, and the corresponding position above the water outlet pipe 300 can be matched with related limiting structures to enhance the structural assembly stability, of course, the related limiting structures can also not be provided, and the clamping portion 3 can also achieve the function of clamping and fixing the water outlet pipe 300.

[0026] The water inlet valve seat of the present application can realize the functions of clamping and fixing the water outlet pipe and connecting during the conventional installation process, and the installation is very simple and convenient, without considering the problem of narrow space inside the faucet or the problem of misalignment or assembly force of the water outlet pipe.

[0027] In a preferred embodiment, the connecting surface 1 is inclined upward, and the connecting surface 1 and the clamping portion 3 form a clamping groove 31 in the shape of a hook. In a further preferred embodiment, the connecting surface 1 and the clamping portion 3 are perpendicular to each other, and the clamping groove 31 formed thereby has a right angle structure.

[0028] With the above scheme, the connecting surface 1 and the clamping portion 3 of the hook-shaped clamping groove 31 are configured as two obliquely arranged clamping surfaces of a hook-shaped opening. In the assembly process, the hook-shaped opening can guide the self-adaptive fine adjustment of the outlet pipe connecting end and accurately extend into the hook-shaped opening. Then, the two clamping surfaces simultaneously clamp and lock the outlet pipe connecting end from different directions. When the clamping angle of the hook-shaped clamping groove 31 is a right angle structure, the outlet pipe connecting end is clamped and locked from the axial and radial directions, thereby ensuring the accuracy of the assembly process and the stability, reliability and sealing performance after assembly. The right angle structure also facilitates mold opening and reduces production costs.

[0029] In a preferred embodiment, two guide portions 4 are arranged on both sides of the corresponding clamping portion 3 on the connecting surface 1, and the two guide portions 4 and the clamping portion 3 form a trapezoidal assembly groove that semi-surrounds the waterway connecting end 2. In this way, in the assembly process, the two guide portions 4 guide the outlet pipe connecting end from both sides in the radial direction, so that the outlet pipe connecting end is adaptively extended into the semi-surrounding trapezoidal assembly groove. The trapezoidal assembly groove semi-encircles and locks the outlet pipe connecting end, thereby ensuring the accurate axial alignment of the outlet pipe connecting end and the waterway connecting end 2 after assembly, and ensuring the effective connection between the two.

[0030] In a preferred embodiment, the top of the valve seat body is an arc surface 5, and the connecting surface 1 is arranged on the side corresponding to the chord 51 of the arc surface 5 and extends upward to the same level as the chord 51. The upward structure extension of the connecting surface 1 plays a certain axial guiding and limiting role, especially in the embodiment where the connecting surface 1 is arranged obliquely, which further ensures that the water inlet valve seat can achieve the function of connecting and fixing the outlet pipe through normal assembly.

[0031] In a preferred embodiment, an annular sealing member 6 is arranged on the outer periphery of the connecting surface 1 corresponding to the waterway connecting end 2. Specifically, one installation mode of the annular sealing member 6 is that a groove 11 is arranged on the connecting surface 1, the annular sealing member 6 is installed in the groove 11, and the outer end of the annular sealing member 6 protrudes out of the connecting surface 1. In this way, in the assembled state of the water inlet valve seat, the clamping portion 3 clamps and fixes the outlet pipe 300, the waterway connecting end 2 is tightly connected with the outlet pipe connecting end, and the connecting surface 1 and the corresponding end surface of the outlet pipe connecting end are tightly abutted and fitted through the annular sealing member 6, thereby greatly improving the sealing performance of the connection part and achieving excellent anti-leakage performance.

[0032] Further, at least one rib 12 is arranged on the groove bottom of the groove 11. The rib 12 is preferably an annular rib surrounding the entire waterway connecting end 2. In specific embodiments, the annular rib has two concentric circular arrangements, and of course, multiple concentric circular arrangements are also possible. The arrangement of the rib 12 can enhance the local pressure of the corresponding annular position of the connection part and improve the sealing performance.

[0033] In a preferred embodiment, the top and / or bottom of the valve seat body is provided with a positioning portion, and in a specific embodiment, the top and bottom of the valve seat body are both provided with a positioning portion, which is a positioning groove 7. During assembly of the water inlet valve seat on the faucet body, the positioning groove 7 and the corresponding positioning protrusion on the faucet body are positioned relative to each other, thereby achieving simple and accurate installation.

[0034] The above merely describes preferred embodiments of the present application, and any equivalent changes and modifications made within the scope of the claims of the present application shall fall within the scope of the claims of the present application.
