Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] See appendix Figure 1 -Appendix Figure 7 The self-venting water cup includes a cup lid 100 with a vent hole 110 and a mounting base 120 on the inner side of the cup lid 100. It also includes a waterproof and breathable component 200 detachably connected to the mounting base 120. The waterproof and breathable component 200 includes a vent hole 210 opposite to the vent hole 110. By detachably connecting the waterproof and breathable component 200 to the inner side of the cup lid 100, the high pressure of water vapor inside the cup can be resolved. Furthermore, the waterproof and breathable component 200 can be directly disassembled to solve the problem of blockage within it, making cleaning convenient and quick. The detachable design of the waterproof and breathable component 200 facilitates manufacturing, reduces the number of parts and sealing areas, lowers the difficulty of disassembly and assembly, and allows customers to easily clean and replace it themselves. Moreover, repeated disassembly and assembly do not easily reduce the sealing performance.

[0026] See appendix Figure 3 -Appendix Figure 5 The waterproof and breathable component 200 includes a connecting seat 220 detachably connected to the mounting base 120. A vent 210 is disposed on the connecting seat 220. A waterproof and breathable membrane 230 communicating with the vent 210 is provided on the connecting seat 220. The mounting base 120 is provided inside the cup lid 100. The mounting base 120 can have an annular sidewall 120 disposed inside the cup lid 100, forming an annular concave structure. It has an outer sidewall 221 that matches the annular sidewall 120. The connecting seat 220 can be directly fitted into the mounting base 120 for fixation, either directly by friction or through a threaded connection, or as described in the attached diagram. Figure 5A snap-fit ​​structure 500 is provided between the annular sidewall 120 and the outer sidewall 221, which enables the mounting base 120 and the connecting base 220 to be detachably connected. A sealing ring 270 is provided between the annular sidewall 120 and the outer sidewall 221 to achieve a good sealing effect after snap-fit. The connecting base 220 has an installation position for accommodating the waterproof and breathable membrane 230. The installation position has a through-hole 210. The waterproof and breathable membrane 230 can be fixed to the connecting base 220 by the sealing block 260 or other pressure blocks. The waterproof and breathable membrane 230 covers the through-hole 210 to achieve communication with the through-hole 210.

[0027] See appendix Figure 3 -Appendix Figure 7 The aforementioned venting structure also includes a valve seat 251 that is sealed to the connecting seat 220. The connecting seat 220 and the valve seat 251 can be sealed by ultrasonic welding or induced welding, which is stable and reliable. A sealing block 260 is provided between the valve seat 251 and the connecting seat 220. That is, the connecting seat 220, the waterproof and breathable membrane 230, the sealing block 260, and the valve seat 251 are an integral structure. The sealing block 260 has a first through hole 261 that communicates with the vent hole 210 and a second through hole 262 that communicates with the vent hole 240, so as to realize the air passage of the vent hole 210, the waterproof and breathable membrane 230, and the first through hole 261, and realize the internal and external communication, which is a structure that is breathable but waterproof.

[0028] Furthermore, a vent hole 240 can be provided opposite to the vent hole 110. The connecting seat 220 is provided with a venting structure communicating with the vent hole 240, so that when the internal air pressure is too high, the venting structure communicates with the outside to relieve pressure. The valve seat 251 is provided with a third through hole 263 communicating with the first through hole 261, so as to realize the air passage of the vent hole 210, the waterproof and breathable membrane 230, the first through hole 261 and the third through hole 263, so as to realize the internal and external communication. It also includes a valve channel 252 communicating with the second through hole 262, and the other end of the valve channel 252 is provided with There is a valve hole 255, and a sealing valve core 253 is sealed to the valve hole 255. An elastic element 254 abuts against the valve channel 252, which realizes the venting channel of the second through hole 262, the valve channel 252, and the valve hole 255. The sealing valve core 253 is sealed to the valve hole 255 to achieve a seal under a certain pressure. When the pressure is too high, the sealing valve core 253 is pushed into the valve channel 252, and the valve core separates from the valve hole 255 to achieve internal and external communication, which can quickly relieve pressure. When the internal pressure decreases, the valve core falls back and abuts against the valve hole 255 to achieve a seal.

[0029] See appendix Figure 1 -Appendix Figure 3The device also includes a cup body 300, with the cup lid 100 hinged to the cup body 300. It also includes a protective cover 400 connected to the cup body 300, which has a hollow layer 410. The protective cover 400 effectively accommodates air and provides heat insulation, ensuring ease of use without affecting the operation of the waterproof and breathable component 200. Furthermore, it includes an elastic sealing layer 280 that covers the mounting base 120 and the waterproof and breathable component 200. The cup body 300 has a cup opening 310, and the elastic sealing layer 280 is sealed to the cup opening 310, with an opening in the elastic sealing layer 280 allowing gas to pass through. Without affecting the ventilation structure of the waterproof and breathable membrane 230 and the sealing valve core 253 inside the valve hole 255, the elastic sealing layer 280 is sealed to the cup mouth 310 to achieve overall cup sealing. The elastic sealing layer 280 is supported by the waterproof and breathable component 200, and the overall structure is stable. It can be well sealed to the cup mouth 310 on the cup body 300. The elastic sealing layer 280 can also protect and seal the waterproof and breathable component 200 to a certain extent. When disassembling and assembling, the waterproof and breathable component 200 and the elastic sealing layer 280 can be unscrewed together, or the elastic sealing layer 280 can be peeled off first and then the waterproof and breathable component 200 can be separated from the mounting base 120.
