[0024] Reference Manual Attached Figure 1 To Attachment Figure 6 A fixing structure of a valve core seat and a hose comprises a shell 1, a valve core seat 2, a clamping ring 3 and a water inlet pipe fitting 4, wherein the valve core seat 2, the clamping ring 3 and the water inlet pipe fitting 4 are all arranged in the shell 1; a connecting channel 22 is provided in the valve core seat 2, and the connecting channel 22 is used to connect with the water inlet pipe fitting 4 to achieve a water channel interconnection effect; one end of the valve core seat 2 also has a connecting body 21, and the water inlet pipe fitting 4 is sealed and connected with the connecting channel 22 after passing through the connecting body 21; a clamping hole 21a is provided on the outer periphery of the connecting body 21, and the clamping hole 21a can be connected and positioned with the buckle of the clamping ring.

[0025] The clamping ring 3 includes a yielding portion, which is used to insert the corresponding water inlet pipe fitting. The inner wall of the yielding portion also has a clamping ring flat position 3a, which can effectively prevent the water inlet pipe fitting from rotating and falling off; the inner wall of the clamping ring 3 is also protruding with a buckle 31, which can be matched and connected with the buckle hole 21a of the connecting body. The water inlet pipe 4 includes a pipe body 4a and a connecting pipe 4b, the connecting pipe 4b includes a sealing section 41b, an upper connecting section 42b and a lower connecting section 43b, the sealing section 41b is inserted into the connecting channel 22 of the valve core seat, and a plurality of sealing rings b are arranged between the sealing section 41b and the valve core seat 2 to ensure the sealing of the connection between the two; the upper connecting section 42b includes a symmetrically arranged upper flat position s1, and the lower connecting section 23b is also provided with a symmetrically arranged lower flat position s2, the upper flat position s1 and the lower flat position s2 are not arranged in the same plane, preferably, the upper flat position s1 and the lower flat position s2 are staggered. The number of water inlet pipes 4 shown in the drawings is two, and in other embodiments, the number of water inlet pipes is one or more to achieve the fixed connection of the present invention.

[0026] Furthermore, a slide groove p is also provided on the connecting body 21 of the valve core seat, and the slide groove p can be temporarily matched and connected with the buckle 31 before the snap ring is pressed into engagement. When the snap ring is pressed into engagement, the buckle 31 is slid out of the slide groove p and then snapped into the snap hole 21a of the connecting body.

[0027] When assembling, refer to the attached Figure 3 , first, insert the clamp ring 3 into the valve core seat 2 to the top; after the upper flat part s1 of the water inlet pipe 4 is aligned with the flat part 3a of the clamp ring, it is inserted into the valve core seat 2 through the clamp ring 3; then, the water inlet pipe 4 is rotated by a certain angle, for example, 90°, so that the four interference parts 44 of the water inlet pipe 4 can cooperate with the valve core seat 2, so that the water inlet pipe 4 is clamped and positioned with the valve core seat 2 by these interference parts 44; finally, slide the clamp ring 3 out of the slide groove p and press it down so that the buckle 31 is buckled into the clamping hole 21a of the valve core seat, refer to the attached Figure 4 To Attachment Figure 6 At this time, the flat part 3a of the clamp ring clamps the water inlet pipe 4, which can prevent the water inlet pipe from rotating and falling off.
