[0028] The bottom of the water inlet pipe 2 is provided with a first connecting structure, and the corresponding cover 5 is provided with a second connecting structure. The cover 5 is detachably connected to the bottom end of the water inlet pipe 2 through the cooperation of the second connecting structure and the first connecting structure. The cover 5 can be installed in an external part mode, and is convenient to disassemble and assemble, and has a simple structure.

[0029] The bottom opening 201 is surrounded by a support step surface 202. The sealing member 4 includes a sealing body 41 made of elastic material and a sealing head 42 integrally connected to the bottom of the sealing body 41. The sealing body 41 is placed in the bottom opening 201, and the sealing head 42 is abutted on the support step surface 202.

[0030] The sealing body 41 is preferentially inserted into the bottom opening 201 in an interference fit, and plays a first layer of sealing role. The sealing head 42 is arranged in a ring shape and is pressed against the support step surface 202, so that the sealing head 42 and the water inlet pipe 2 play a second layer of sealing role, improve the leakage prevention effect, and avoid that the sealing body 41 is too deep into the water inlet pipe 2, thereby blocking the water inlet pipe 2.

[0031] The bottom surface of the sealing body 41 is provided with at least one ring 43, which is abutted with the inner wall surface of the top of the cover 5. After the sealing member 4 is inserted into the bottom opening 201, the bottom surface of the sealing body 41 is flush with the bottom end surface of the water inlet pipe 2. After the cover 5 is installed in place, the ring 43 is abutted with the cover 5, which helps the tightness of the sealing body 41 inserted into the bottom opening 201 and increases the pressure of the sealing head 42 abutted on the support step surface 202, thereby improving the sealing effect.

[0032] The first connecting structure includes two or more reverse buckling portions 21 uniformly distributed on the outer wall of the water inlet pipe 2, and the reverse buckling portion 21 is provided with a guide inclined surface 211.

The cover wall 51 of the cover 5 is buckled on the outer side of the water inlet pipe 2, and the reverse buckling opening 511 is arranged on the cover wall 51 of the cover 5. The cover 5 is detachably connected to the water inlet pipe 2 by buckling, which is simple to operate. The first connecting structure and the second connecting structure can be integrally formed during production, which improves production efficiency, has a simple and conventional structure, and has good buckling stability.

[0033] The central part of the lower connector 1 is provided with a lower installation channel 101, and the water inlet pipe 2 is movably connected in the lower installation channel 101. The bottom of the lower installation channel 101 is fixedly provided with a stop structure 102, and the upper part and the lower part of the water inlet pipe 2 are respectively provided with an upper limiting structure and a lower limiting structure matched with the stop structure 102.

[0034] The stop structure 102 is a ring structure and is in clearance fit with the water inlet pipe 2. When the water inlet pipe 2 is installed, the upper limiting structure is fixed to the upper portion of the water inlet pipe 2, thereby avoiding the water inlet pipe 2 from sliding downward. Then the water inlet pipe 2 is inserted into the lower installation channel 101 from the upper side of the lower connector 1 downward until the lower limiting structure pushes away the stop structure 102 and slides to the lower side of the stop structure 102, so that the lower limiting structure abuts against the stop structure 102, thereby ensuring that the water inlet pipe 2 cannot be pulled out from the upper side.

[0035] In the embodiment, the upper limiting structure comprises a limiting support sleeve 6 which is detachably sleeved on the water inlet pipe 2 at a position corresponding to the height of the lower installation channel 101 through a connecting assembly. The outer wall of the limiting support sleeve 6 extends circumferentially with a plurality of support protrusions 61 of the same length which abut against or are adjacent to the inner wall surface of the lower installation channel 101. Through the plurality of support protrusions 61 extending radially, the water inlet pipe 2 can be kept centered in the lower installation channel 101, which is helpful for the plug-in fit of the upper sealing assembly 8 in the upper connector 7.

[0036] Specifically, the connecting assembly comprises two or more groups of screwing protrusions 22 and L-shaped rotating screwing grooves 62. The screwing protrusions 22 are arranged on the outer wall of the water inlet pipe 2, and the rotating screwing grooves 62 are arranged on the limiting support sleeve 6. The limiting support sleeve 6 is circumferentially and rotationally buckled on the water inlet pipe 2 through the rotating screwing grooves 62 and the screwing protrusions 22. The installation is convenient and fast through the rotating buckling mode.

[0037] The lower limiting structure comprises opposite extending limiting reverse buckling portions 23, and the stop structure 102 is provided with elastic buckling lugs 103 matched with the limiting reverse buckling portions 23.

[0038] In addition, as shown in Figure 4 The outer wall of the water inlet pipe 2 is further provided with an inner stop rotating protrusion 24. One side of the inner stop rotating protrusion 24 is provided with an inner arc-shaped guide surface 241, and the other side is provided with a fixed stop surface 242.

[0039] The inner wall of the limiting support sleeve 6 is provided with a recessed surface corresponding to the inner stop rotating protrusion 24. The recessed surface is provided with an outer stop rotating protrusion 63. One side of the outer stop rotating protrusion 63 is provided with a movable stop surface 631 which abuts against the fixed stop surface 242 after the limiting support sleeve 6 is buckled in place. The other side is provided with an outer arc-shaped guide surface 632 which cooperates with the inner arc-shaped guide surface 241 when the limiting support sleeve 6 is circumferentially rotated.

[0040] Through the cooperation of the inner stop rotating protrusion 24 and the outer stop rotating protrusion 63, after the limiting support sleeve 6 is circumferentially rotated and buckled in place, the movable stop surface 631 and the fixed stop surface 242 abut against each other, thereby avoiding the reverse rotation of the limiting support sleeve 6 and causing the loosening of the limiting support sleeve 6.

[0041] Furthermore, the outer wall of the water inlet pipe 2 is provided with guide ribs 25 extending in the height direction, and the stop structure 102 is provided with guide openings 104 that form a linear sliding fit with the guide ribs 25.

[0042] It also includes an upper connector 7, on which an upper sealing assembly 8 is mounted in the center, for reference. Figure 5 As shown, the water outlet port at the upper part of the water inlet pipe 2 is provided with a pin 26. The pin 26 extends upward from the pipe cavity to the upper side of the water outlet port and abuts against the sealing structure in the upper sealing assembly 8.

[0043] The outer periphery of the ejector pin 26 is provided with two or more connecting parts 261, and the ejector pin 26 is integrally formed with the water inlet pipe 2 through the connecting parts 261.

[0044] The upper sealing component 8 is referenced. Figure 6 As shown, it mainly includes a valve body 81. Inside the valve body 81, from top to bottom, there is a return spring 82, a sealing steel ball 83, and a silicone sealing sleeve 84. The sealing steel ball 83 will abut against the upper side of the silicone sealing sleeve 84. After the upper connector 7 and the lower connector 1 are coupled, the sealing steel ball 83 is actively lifted away from the silicone sealing sleeve 84 by the ejector pin 26, which can solve the problem of adsorption between the silicone sealing sleeve 84 and the sealing steel ball 83. Example 2:

[0045] Example 2 differs from Example 1 in that: (Refer to...) Figure 7 As shown, the sealing element 4 is tightly embedded in the cavity of the water inlet pipe 2 and close to the bottom opening 201. Several welding protrusions 203 are arranged circumferentially on the supporting step surface 202 on the outer periphery of the bottom opening 201. The cover 5 is tightly embedded in the bottom opening 201 and abuts against the supporting step surface 202 to block the sealing element 4. The edge of the cover 5 extends with a welding rib 501 corresponding to the supporting step surface 202. After the cover 5 abuts against the supporting step surface 202, the welding protrusions 203 and welding ribs 501 are heat-fused by ultrasonic welding to fix the cover 5 in the bottom opening 201.

[0046] In addition, a through hole 502 is provided in the center of the cover 5. The through hole 502 allows the air between the sealing element 4 and the cover 5 to be discharged when the cover 5 is installed, thus playing a role in pressure relief.

[0047] Furthermore, in Embodiment 2, the sealing element 4 is at least frustum-shaped at the top, which serves as a guide and helps the sealing element 4 to be inserted into the cavity of the water inlet pipe 2, thereby improving assembly efficiency.
