[0050] Embodiment 2:

[0051] Based on the embodiment 1, the water filling valve 100 of the present application comprises the exhaust core 110, the upper shell 120 and the front end assembly 130, and the present embodiment further limits the structure thereof.

[0052] In some implementations, the first sealing part 160 is a first sealing groove opened on the side of the first end part 111, and the first sealing groove has a first tangent surface 161; the second sealing part 170 is a sealing protrusion arranged at the end of the flow guide pipe 131, and the sealing protrusion has a second tangent surface 171 which is in close contact with the first tangent surface 161. In the present embodiment, the first sealing part 160 and the second sealing part 170 are in close contact with each other, and the included angle between the first tangent surface 161 and the second tangent surface 171 and the horizontal plane is 45°; so that the first sealing part 160 and the second sealing part 170 are sealingly connected when the water filling valve 100 is closed, and the liquid is prevented from flowing out.

[0053] Different from the above implementations, the first sealing groove can be arranged on the flow guide pipe 131, and the sealing protrusion can be arranged on the first end part 111.

[0054] In some implementations, the front end assembly 130 further comprises a connecting pipe 132 and a connecting sleeve 133, one end of the connecting pipe 132 extends into the first cavity and is sealingly connected with the side wall of the upper shell 120, and the other end of the connecting pipe 132 is fixedly connected with the connecting sleeve 133; the connecting pipe 132 and the connecting sleeve 133 are both sleeved outside the flow guide pipe 131. In the present implementation, the connecting pipe 132 and the connecting sleeve 133 can be fixed by screwing, i.e. the upper end of the connecting sleeve 133 is provided with an internal thread, the lower end of the connecting pipe 132 is provided with an external thread, and the connecting pipe 132 and the connecting sleeve 133 are fixed by screwing. The connecting pipe 132 and the connecting sleeve 133 are both hollow and in the shape of a cylinder, the upper end of the connecting pipe 132 forms a liquid passage and the lower end is sealingly sleeved on the outer surface of the flow guide pipe 131, and the connecting sleeve 133 is fixedly sleeved on the flow guide pipe 131.

[0055] In some implementations, the front end assembly 130 further comprises a silica gel pad 134; the end of the connecting sleeve 133 away from the connecting pipe 132 is provided with a mounting groove, and the silica gel pad 134 is sleeved on the outer layer of the flow guide pipe 131 and fixedly arranged in the mounting groove. In the present implementation, the lower surface of the front end assembly 130 can serve as a stress surface for receiving the abutting force. The abutting force can be generated by the water bottle rising and abutting against the front end assembly 130; in the present embodiment, the front end assembly 130 further abuts against the water bottle through the silica gel pad 134, thereby providing buffer protection for the rising water bottle.

[0056] In some implementations, a first sealing ring 135 is provided on the outside of the connecting tube 132, sealingly connecting the connecting tube 132 to the upper housing 120 via the first sealing ring 135. A second sealing ring 136 is provided on the inside of the connecting tube 132, sealingly connecting the connecting tube 132 to the flow conduit 131 via the second sealing ring 136. In this implementation, by providing a sealed connection between the connecting tube 132, the upper housing 120, and the flow conduit 131, liquid can be prevented from leaking out of the connection gap of the irrigation valve 100, thereby improving the sealing performance of the irrigation valve 100.

[0057] In some implementations, an elastic member 140 is further included. A first retaining groove is provided on the outer surface of the upper shell 120, and a second retaining groove is provided on the upper end of the connecting sleeve 133. The elastic member 140 is positioned and connected between the first and second retaining grooves to enable the upper shell 120 and the front end assembly 130 to be movably connected. In the present invention, when the front end assembly 130 is not subjected to abutting forces, gravity or the elastic force of the elastic member 140 can naturally push the flow conduit 131 toward the exhaust valve, thereby closing the water outlet 150 by abutting the first and second sealing members 160 and 170. When the front end assembly 130 is subjected to abutting forces, it moves toward the upper shell 120 in the direction of the abutting force, so that the exhaust core 110 and the flow conduit 131 form the water outlet 150, and the water inlet 122, the first and second cavities are connected to the water outlet 150 to fill the water bottle.

[0058] In some implementations, the exhaust core 110 has a snap-fitting boss 114 on its outer surface. A thread 115 is also formed on the outer surface of the exhaust core 110, located on the side of the snap-fitting boss 114 away from the exhaust hole 113. The upper housing 120 is inserted into the exhaust core 110 in a direction closer to the exhaust hole 113, locked in place by the snap-fitting boss 114 and secured by a nut 116 and thread 115. The exhaust core 110 is secured to the upper housing 120 through the snap-fitting boss and nut 116, and then secured to the water tank 200 through the upper housing 120.

[0059] In some implementations, the exhaust core 110 further includes a core body 112, with an exhaust hole 113 disposed on the core body 112. The diameter of the core body 112 is smaller than the diameter of the first end portion 111, so that when the first sealing component 160 and the second sealing component 170 are separated, the exhaust core 110 and the flow guide tube 131 form a water outlet 150. The front end assembly 130 is movably connected to the upper shell 120. That is, when the front end assembly 130 is subjected to force, the front end assembly 130 moves along the upper shell 120, forming the water outlet 150 between the exhaust core 110 and the flow guide tube 131, and connecting the water inlet 122, the first cavity, the second cavity, and the water outlet 150 to fill the water bottle.
