DETAILED DESCRIPTION

[0032] In the related art, in order to prevent the fragrance in the scent cup from being lost when not in use, the scent cup is often provided with a one-way valve at the position of the air inlet. The one-way valve allows outside air to enter while preventing the internal fragrance from escaping, thereby preventing the loss of fragrance in the cup. However, it is precisely because of the design of this one-way valve that users need to overcome additional resistance when absorbing water, so that users must suck water hard to open the one-way valve to allow outside air to flow into the cup body. This situation is particularly obvious when drinking water continuously, which brings inconvenience to users. The difficulty in absorbing water not only affects the user experience, but may also cause users to reduce their water intake in some cases, which is a disadvantage for people who need to replenish their water intake. In addition, long-term forceful absorbing of water may also cause discomfort to the user's mouth and throat.

[0033] In order to solve the above problems, the present application provides a cup cover and a scent cup with good sealing function. The cup cover and the scent cup are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figure 1-9As shown, a scent cup with a good sealing function provided in this embodiment includes a cup body 7 and a cup lid, which are connected to each other. The good sealing function of the scent cup is provided by the cup lid, which includes an inner lid body 1, a straw member 2, a scent attachment 3, and an elastic member 4. The scent attachment 3 is mounted on the inner lid body 1 and is provided with a first air inlet 31, an inner cavity, and a first air outlet 32, which are connected in sequence. The straw member 2 is axially movable and inserted into the inner lid body 1. The wall of the straw member 2 is provided with a second air inlet 211. The straw member 2 has an open position and a closed position. In the open position, the second air inlet 211 is connected to the first air outlet 32. In the closed position, the second air inlet 211 and the first air outlet 32 ​​are separated. The straw member 2 can switch from the open position to the closed position under the action of an external force. The elastic member 4 is used to apply an elastic restoring force to the straw member 2 to connect the second air inlet 211 with the first air outlet 32.

[0035] Specifically, the elastic member 4 can be provided between the straw member 2 and the inner cover 1, or between the straw member 2 and the scent attachment 3. Of course, in other implementations, the elastic member 4 can be provided between the straw member 2 and the inner cover 1, and between the straw member 2 and the scent attachment 3. The elastic member 4 can be configured as a compression spring or a tension spring, and the elastic member 4 only needs to provide the elastic restoring force required for the straw member 2 to switch from the closed position to the open position.

[0036] The technical solution of this embodiment cleverly solves the problem of difficulty in absorbing water caused by the use of a one-way valve to achieve good sealing in the related art by innovatively designing a cup cover structure with an inner cover body 1, a straw member 2 and an odor attachment 3. Specifically, the straw member 2 is inserted into the inner cover body 1, and an odor attachment 3 is provided on the outer periphery of the straw member 2. The odor attachment 3 has a first air inlet 31, an inner cavity and a first air outlet 32 ​​that are connected in sequence, and the straw member 2 itself is provided with a second air inlet 211. At the same time, the cup cover also includes an elastic member 4, which plays a key regulating role in the entire device. When the straw member 2 bounces up under the action of the elastic member 4, the second air inlet 211 is connected to the first air outlet 32, and the straw member 2 is in an open state, allowing outside air to enter smoothly, reducing the resistance to water absorption and greatly improving the difficulty in absorbing water. When the user presses down on the straw member 2, the second air inlet 211 separates from the first air outlet 32 ​​as the straw member 2 moves downward, closing the straw member 2 and restoring the lid's seal, preventing liquid leakage. This structural design not only effectively seals the lid but also solves the problem of water absorption difficulties by controlling the airflow path, achieving the innovative effect of ensuring a good seal without a one-way valve.

[0037] Preferably, a fragrance seal ring 5 is provided at the second air inlet 211. This arrangement not only further optimizes the sealing performance of the cup lid but also enriches the user experience. The presence of the fragrance seal ring 5 ensures a tight seal. When the straw 2 is inflated, the second air inlet 211 communicates with the first air outlet 32. The fragrance seal ring 5 effectively prevents impurities or odors from the outside air from entering the cup through the connection between the second air inlet 211 and the first air outlet 32, thereby ensuring the purity of the liquid within the cup.

[0038] Preferably, the inner cover 1 is provided with a plurality of vents 11 connecting the outside world and the inside of the cup, and a protruding ring 212 is provided on the outer wall of the straw member 2. When the straw member 2 is in the closed position, the protruding ring 212 blocks the vents 11. In the open position, the vents 11 connect the outside world and the inside of the cup body 7.

[0039] In this preferred embodiment, a number of air vents 11 are provided on the inner cover body 1, aiming to better balance the sealing performance of the cup cover and the difficulty of the user in absorbing water. When the straw member 2 is in an open state under the action of the elastic member 4, the provision of the air vents 11 enables the air inside and outside the cup to be exchanged through these air vents 11, avoiding the difficulty in absorbing water due to the difference in air pressure. When the user presses down the straw member 2 to put the straw member 2 in the closed position, the convex ring 212 on the straw member 2 will block the air vent 11, thereby automatically closing the air passage when sealing is required, ensuring that the liquid will not leak out. This control structure between sealing and ventilation makes the cup cover more convenient to use and avoids the risk of leakage caused by the open air vent 11 in the traditional design.

[0040] Preferably, the inner cover body 1 includes an inner cover body 12 , which is cylindrical, the straw member 2 is inserted into the inner cover body 12 , and the convex ring 212 is located inside the inner cover body 12 , and the elastic member 4 abuts between the convex ring 212 and the bottom wall of the inner cover body 12 .

[0041] With such arrangement, the cavity formed inside the inner cover body 12 can be used to install the elastic member 4, thereby reducing the risk of displacement of the elastic member 4. The convex ring 212 can also be limited to axially limit the straw member 2. In addition, the air vent 11 is arranged on the bottom wall of the inner cover body 12, which can also reduce the risk of liquid inside the cup body 7 leaking through the air vent 11.

[0042] When the inner cover body 12 includes the inner cover body 12, the inner cover body 12 includes a top wall and a bottom wall arranged opposite to each other and an annular outer wall connected between the top wall and the bottom wall. The straw member 2 passes through the top wall and the bottom wall of the inner cover body 12 at the same time. The air vent 11 is arranged on the bottom wall of the inner cover body 1, and a breathable gap is formed between the top wall and the annular outer wall of the inner cover body 1. External air can enter the internal space of the inner cover body 1 along the breathable gap, and then further enter the interior of the cup body 7 through the air vent 11.

[0043] Preferably, the air vent 11 is sleeved with an air inlet rubber ring 6, and the air inlet rubber ring 6 is provided with a plurality of rubber ring air inlets 61. In the preferred embodiment, by sleeve-mounting the air inlet rubber ring 6 at the air vent 11 and designing a plurality of air inlets on the rubber ring, this improved solution significantly enhances the sealing and air permeability of the cup lid. The air inlet rubber ring 6 acts like a sealing gasket. It fits tightly against the edge of the air vent 11, ensuring that air only enters through the designed air inlet and does not penetrate into the cup through other gaps or uncontrolled pathways. The design of this rubber ring air inlet 61 not only ensures the entry of an appropriate amount of air and balances the pressure difference between the inside and outside of the cup, but also effectively prevents external impurities or water vapor from entering the cup, further improving the safety and purity of the liquid in the cup. In addition, this air inlet rubber ring 6 can also play a certain buffering role, reducing the wear on the edge of the air vent 11 during the opening and closing process of the cup lid, thereby extending the service life of the cup lid. Preferably, the air inlet rubber ring 6 is conical, and a sealing protrusion 62 is provided on the inner side of the air inlet rubber ring 6. By designing the air inlet rubber ring 6 as a conical structure and providing a sealing protrusion 62 on its inner side, the sealing performance and functional stability of the cup lid are further improved. The air inlet rubber ring 6 with a conical structure can achieve a tighter fit during use. Its conical design allows the air inlet rubber ring 6 to fit more closely with the air vent 11 during installation. It can not only automatically adjust to the optimal position after applying a certain pressure, but also adapt to slight changes under different pressure conditions, thereby always maintaining a sealing effect. In addition, the sealing protrusions 62 on the inner side of the air inlet rubber ring 6 play a double role of protection. These protrusions can provide additional sealing pressure when the air inlet rubber ring 6 contacts the edge of the air vent 11, further preventing air, liquid or other substances from leaking from the air vent 11.

[0044] Preferably, the material of the air intake rubber ring 6 is silicone. Silicone is selected as the material of the air intake rubber ring 6 in order to further optimize the sealing performance, durability and user experience of the cup lid. As a high-performance elastic material, silicone has excellent high temperature resistance, low temperature resistance, aging resistance and tear resistance, which enables the air intake rubber ring 6 to maintain stable performance under various environmental conditions. The softness and elasticity of silicone enable it to fit tightly with the air vent 11 when the cup lid is closed, thereby achieving effective sealing. This material can quickly return to its original shape when subjected to external force, ensuring that the air intake rubber ring 6 will not lose its sealing function due to deformation during long-term use. Silicone also has good chemical stability and will not react with the beverage in the cup, thereby maintaining the purity of the beverage and will not release harmful substances due to contact with food or liquids.

[0045] Preferably, the straw assembly 2 includes a nozzle portion 21 and a tube body 22, which are snap-fitted together, with the second air inlet 211 located on the nozzle portion 21. In this technical solution, the straw assembly 2 is separated into the nozzle portion 21 and the tube body 22, which are assembled and used together using a snap-fit ​​method. The second air inlet 211 is also located on the nozzle portion 21. This design further optimizes the structure of the cup lid. The snap-fitting method between the nozzle portion 21 and the tube body 22 simplifies the assembly and disassembly of the straw assembly 2, making it easy for users to clean and maintain it.

[0046] Preferably, the scent attachment 3 is annular, mounted on the inner cover 1 and sleeved onto the straw 2. By designing the scent attachment 3 as an annular structure, the annular scent attachment 3 has a uniform distribution property, and its annular structure evenly releases fragrance or other odors during use. This not only enhances the user's sensory experience, but also provides a more pleasant user experience.

[0047] Furthermore, the scent cup further includes an outer cover 8, which closes the straw 2 when the outer cover 8 is placed on the cup body 7. This arrangement allows the straw 2 to automatically close when the outer cover 8 is placed on the cup body 7, minimizing the loss of scent when the scent cup is not in use.

[0048] Preferably, the outer cover 8 is provided with a sealing gasket 81. When the outer cover 8 is placed on the cup lid, the sealing gasket 81 and the straw member 2 abut against each other to seal the straw member 2. When the outer cover 8 is placed on the cup lid, the straw member 2 is sealed. The introduction of this design further optimizes the overall sealing performance of the scent cup and enhances the protective function of the cup lid, which is of significant preference. First, the introduction of the outer cover 8 provides the scent cup with an additional layer of protection. This protective layer not only effectively prevents external dust, impurities, or microorganisms from entering the cup, but also provides additional protection when the cup lid or straw member 2 is impacted by external forces, reducing the risk of damage or deformation of the cup lid due to collisions or falls.

[0049] Secondly, when the outer cover 8 is placed on the cup lid, the sealing gasket 81 abuts against the straw part 2, thereby sealing the straw part 2. This sealing process not only prevents the leakage of liquid, but also effectively prevents the entry of air. In particular, during the carrying process, the presence of the sealing gasket 81 can ensure that even if the cup is bumped or tipped over, the liquid in the cup will not leak out. In addition, the sealing effect of the sealing gasket 81 and the straw part 2 can also prevent the odor in the cup from overflowing, ensuring that the odor cup can maintain the stability of the internal odor for a long time, further enhancing the user experience. In addition, this combination design of the outer cover 8 and the sealing gasket 81 is also easy to use. The user only needs to simply cover the outer cover 8 to achieve a quick seal through the contact between the sealing gasket 81 and the straw part 2 without the need for complicated operations. This design is particularly suitable for occasions that require frequent use, such as daily commuting or outdoor activities. The user can quickly complete the sealing operation of the cup lid to ensure the safety and cleanliness of the drink.
