[0002] With the increase of people's demand for portable drinking utensils, the sealing, air permeability and convenience of water cups become the design focus. The traditional cup cover usually adopts a completely sealed structure, but when hot drinks are contained or shaken, negative pressure is easily generated in the cup, leading to difficulty in opening the cover or liquid spilling. To solve this problem, the existing technology often balances air pressure by setting air holes on the cup cover. However, such design has the following defects:

[0003] The above-mentioned existing cup cover air permeability solution generally faces two major challenges: on the one hand, ordinary air holes cannot completely prevent liquid leakage, especially when the cup body is tilted or shaken, which easily causes liquid overflow, affecting the safety and reliability of use; on the other hand, some products with high leakage prevention performance often require complex structural support, which not only increases the manufacturing cost and assembly difficulty, but also may cause component aging or damage during long-term use, thereby reducing the overall life of the product. SUMMARY

[0005] To achieve the above-mentioned purpose, in a first aspect, the application provides a cup cover, comprising a top cover, a sealing cover, a waterproof air permeable member and a pressing net, the waterproof air permeable member is located between the top cover and the pressing net or between the sealing cover and the pressing net, the sealing cover is provided with a through hole, the pressing net covers the through hole and is provided with air holes corresponding to the through hole, the top cover is fixedly connected with the pressing net at an end away from the waterproof air permeable member and encloses an air cavity, the air holes are in communication with the air cavity, and the top cover is provided with an exhaust hole in communication with the air cavity.

[0006] Through the above-mentioned technical solution, the waterproof air permeable member is clamped between the sealing cover and the pressing net, the air holes of the pressing net correspond to the through hole of the sealing cover, forming a directional air permeation channel, so that the gas in the cup can be sequentially discharged through the through hole, the air hole, the air cavity and the exhaust hole, while the waterproof air permeable member blocks the liquid leakage, balancing the air permeability and the sealing property; the top cover is fixedly connected with the pressing net to form the air cavity, which simplifies the assembly structure and ensures the stability of the air path.

[0007] In combination with the first aspect, further technical solutions, the top cover is connected with a pressing member, the pressing member abuts against the pressing net or the waterproof air permeable member to keep the pressing net and the waterproof air permeable member in abutment.

[0008] By the technical scheme, the pressing part applies uniform axial pressing force to the waterproof and breathable part by abutting against the pressing net, avoids loosening of the waterproof and breathable part due to vibration or temperature change, and ensures long-term sealing effect.

[0009] In combination with the first aspect, in a further technical scheme, the pressing part is provided with a reinforcing rib, and the reinforcing rib is located at an end away from the waterproof and breathable part.

[0010] By the technical scheme, the reinforcing rib is arranged at an end of the pressing part away from the waterproof and breathable part, so that the structural strength of the pressing part is enhanced to prevent deformation of the pressing part under pressure, and meanwhile, the reinforcing rib avoids interfering with the pressing contact surface of the waterproof and breathable part.

[0011] In combination with the first aspect, in a further technical scheme, in the axial direction of the pressing part, the length of the reinforcing rib is less than the height of the pressing part.

[0014] By the technical scheme, the flange of the pressing part and the pressing rib of the top cover abut against each other to form an axial limiting structure, so that the pressing part is prevented from being deviated during assembly or use, and meanwhile, the pressing force is dispersed to improve the structural stability.

[0015] In combination with the first aspect, in a further technical scheme, the top cover is provided with a positioning rib for preventing the pressing net from moving away from the axial direction.

[0016] By the technical scheme, the positioning rib limits the displacement of the pressing net in the radial direction, so that the air holes of the pressing net are always aligned with the through hole of the sealing cover, and the air passage is prevented from being blocked due to misalignment of the pressing net.

[0017] In a second aspect, the application provides a cup cover assembly, which comprises the cup cover of the first aspect and a main body, the top cover and the main body are rotationally connected through a rotating shaft, on a side away from the rotating shaft, the top cover and the main body are connected through a switch assembly, the main body is provided with a water outlet, and the water outlet is communicated with the exhaust hole through the through hole, the pressing net and the air cavity.

[0019] With reference to the second aspect, in a further implementation form of the second aspect, the outer periphery of the water outlet is provided with a ring rib, an end surface of the ring rib is a bevel surface, and a highest point of the end surface of the ring rib is offset from the rotating shaft and the switch assembly.

[0020] With the above technical solution, the bevel surface of the ring rib can guide the liquid to flow to the center of the water outlet, reducing liquid residue when closed; the highest point is offset from the rotating shaft and the switch assembly, reducing the interference with the mouth when drinking water, and also having the advantage that the bevel surface of the ring rib preferentially contacts the edge of the water outlet when the top cover is closed, enhancing the uniformity of the sealing.

[0021] In a third aspect, the application provides a water cup including the cup cover assembly of the second aspect.

[0022] With the above technical solution, the cup cover assembly is combined with the cup body to achieve liquid sealing while ensuring air permeability, which is suitable for scenarios of containing hot drinks or easily generating air pressure changes, and improves the safety and convenience of use.

[0023] With reference to the third aspect, in a further implementation form of the third aspect, the cup cover and the cup body are threadedly connected, and the waterproof and air-permeable member is configured to allow gas in an inner cavity of the cup body to pass through and prevent water in the inner cavity from flowing out.

[0024] With the above technical solution, the thread connection of the cup cover and the cup body ensures the stability of assembly; the gas permeability and liquid blocking of the waterproof and air-permeable member further prevent liquid leakage when inverted or shaken, while maintaining the air pressure balance in the cup.

[0047] The embodiments of the present application will be described in detail below with reference to the drawings. The features in the following embodiments can be combined with each other without conflict.

[0048] Embodiment 1

[0049] Please refer to Figures 1-2 The cup cover 100 provided by the embodiments of the present application includes a top cover 1, a sealing cover 5, a waterproof and breathable member, a pressing member 2 and a pressing net 3, wherein the waterproof and breathable member is located between the pressing member 2 and the pressing net 3, the sealing cover 5 is provided with a through hole 51, the pressing net 3 covers the through hole 51 and is provided with an air hole 31 corresponding to the through hole 51, the top cover 1 is fixedly connected with the pressing net 3 away from the waterproof and breathable member and encloses an air cavity 13, the air hole 31 is in communication with the air cavity 13, and the top cover 1 is provided with an exhaust hole 11 in communication with the air cavity 13, which achieves the effect of effectively preventing liquid leakage while ensuring breathability. The waterproof and breathable member in the present embodiment is a waterproof and breathable film 4, and other materials or structures that can ventilate but not pass water can also be used.

[0050] Specifically, the top cover 1 is made of high-strength plastic, which has good impact resistance and wear resistance; the sealing cover 5 is made of soft silica gel material, which can tightly fit the pressing net 3 and reduce the possibility of gas leakage. The top cover 1 and the pressing net 3 are firmly connected by ultrasonic welding process, forming a stable double-layer structure.

[0051] The through hole 51 on the sealing cover 5 is about 2mm in diameter, which is moderate in size and can meet the demand of air flow, and will not cause liquid to easily seep out because of being too large.

[0052] The waterproof and breathable film 4 is a special material film, which has micron-level pore size, allowing air molecules to freely enter and exit, but can block larger liquid droplets from penetrating. This film can be fixed on the press net 3 by a hot melting method, ensuring its long-term stable operation without falling off. In addition, the waterproof and breathable film 4 is coated with a hydrophobic coating on the surface, further reducing the risk of moisture intrusion.

[0053] The function of the pressing part 2 is to apply appropriate pressure to the waterproof and breathable film 4, so that it always maintains a flat state and avoids deformation caused by vibration or extrusion. The pressing part 2 is similar to a cylinder, with several reinforcing ribs 12 evenly distributed around the periphery, penetrating the upper and lower end faces, forming a grid-shaped reinforcing frame structure. The purpose of this arrangement is mainly to disperse the stress concentration point position, avoiding the risk of local stress being too high causing fracture.

[0054] In addition, in order to further optimize the structural stability of the pressing part 2, the length of the reinforcing rib 12 is less than the height of the pressing part 2 along the axial direction of the pressing part 2. This design can save material usage while ensuring sufficient support strength, and make the overall appearance more beautiful and compact. In other cases, the pressing part 2 can also be additionally provided with a flange 21, and the top cover 1 is correspondingly provided with a pressing rib 14 surrounding the outer periphery of the pressing part 2 and abutting against the flange 21, so as to firmly fix the pressing part 2 and prevent it from accidentally falling off.

[0055] The working principle of the whole device is as follows: when the pressure inside the cup body 303 is too large or too small, the gas in the cup body 303 can enter and exit through the waterproof and breathable film 4, but the waterproof and breathable film 4 can block the liquid in the cup body 303 from flowing out.

[0056] It is worth noting that although specific parameter values are listed as example references, in fact these values can be flexibly adjusted according to specific needs. For example, for a water bottle for children, considering safety factors, it is recommended to reduce the size of the through hole 51 to about 1.5mm; while for a sports thermos, it can be expanded to 3mm in order to release the steam heat faster.

[0057] Embodiment 2

[0058] Please refer to Figure 3 The difference between this embodiment and the above-mentioned embodiments is that the waterproof and breathable film 4 is arranged between the press net 3 and the sealing cover 5, and is fixed by the close fixing between the press net 3 and the sealing cover 5, which can effectively block the water in the cup from flowing into the air cavity 13 of the cup cover 100, and reduce the risk of water entering the air cavity 13 and flowing out from the exhaust hole 11.

The main body 201 is provided with a water outlet 204, and the water outlet 204 is communicated with the exhaust hole 11 through the through hole 51, the pressing net 3, and the air cavity 13.

[0061] Referring to Figure 6 and Figure 7 , in order to improve the smoothness of water outlet and facilitate cleaning and maintenance, the outer periphery of the water outlet 204 is provided with a ring rib 205, and the end face of the ring rib 205 is an inclined surface, and the highest point of the end face deviates from the rotating shaft 203 and the switch assembly 202. This unique layout enables the water flow direction to be guided, reducing the probability of interference between the face of the person drinking water and the rotating shaft 203, the switch assembly 202 and the like, while also enhancing the structural rigidity.

[0062] Embodiment 4

[0063] Referring to Figures 8-10 , the embodiment discloses a water cup 300, comprising the cup cover assembly 200 in the embodiment 3, an outer cover 301, a handle 302, and a cup body 303, the handle 302 is fixedly installed on the cup body 303, the outer cover 301 is detachably connected with the cup body 303, and the cup cover assembly 200 is threadedly connected with the cup body 303.
