Description

Technical Field

[0001] The utility model relates to the technical field of drinking containers, in particular to an inner plug cover with a spring cover structure and a hand-held kettle equipped with the inner plug cover. Background Art

[0002] The flip-cap structure is a common structure on drinking containers. It is usually configured on the cover body. Users can quickly open and close the cover body by simply pressing or pushing with their fingers. Compared with the threaded connection method of the cover body, it can be operated with one hand, which simplifies the operation that requires repeated rotation, making it simpler and more intuitive. In addition, the cover body of the flip-cap structure cannot be completely separated from the container body, which can also prevent the cover body from being lost when used by the user.

[0003] Common control methods of the spring-cap structure include pressing and sliding. The Chinese patent with publication number CN220655310U and patent name "A spring-cap water cup" discloses a water cup with a spring-cap structure controlled by pressing, which includes a cup body with an opening on one side, a spring-cap assembly hinged at the opening of the cup body, and a filter box assembly arranged inside the cup body. The spring-cap assembly includes a threaded base, an elastic cover, an elastic button, and a suction nozzle. The threaded base is inserted into the threaded groove and threadedly mounted on the cup body. A drinking port and a water suction port are opened on the side of the threaded base away from the cup body. The drinking port and the water suction port are arranged at intervals, so that users can have multiple choices of drinking methods. The elastic cover is hinged on the threaded base through a rotating shaft to block the drinking outlet, and the elastic button is installed on the threaded base to limit the rotation and opening of the elastic cover; for example, the Chinese patent with publication number CN211795726U and patent name "A bouncing thermos cup cover" discloses a sliding-controlled bouncing cover structure, which is unlocked by setting a slide groove and a slider, and utilizing the movement of the slider in the slide groove, and a button is set on the side wall of the cup cover body.

[0004] At present, the above two control modes of the flip-cover structure have the following problems: when the drinking container contains hot drinks and the temperature of the hot drinks drops, the movement of water molecules slows down, the volume shrinks, the pressure inside the drinking container decreases, and negative pressure is formed. At this time, the outer side of the cover is affected by the atmospheric pressure, so that a pressure difference is formed between the inner and outer sides, and then the cover is pressed more firmly on the drinking container, resulting in the flip-cover structure often being unable to overcome the negative pressure in the drinking container, reducing the success rate of unlocking the flip-cover, causing the flip-cover structure to fail, and affecting the user experience.

[0040] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. It is only for the convenience of simplifying the description, rather than indicating or implying that the orientation must have a specific orientation and specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present utility model.

[0042] As Figure 1 、 Figure 2 shown, the present utility model first relates to an inner plug cover with an elastic cover structure, which includes an inner plug cover a1 disposed inside the top of a drinking container. The inner plug cover a1 includes an upper cover 2 and a lower cover 3. The upper cover 2 and the lower cover 3 are rotatably connected. The upper cover 2 can be turned up and down around the rotation connection position. It can be covered and locked to the lower cover 3 by turning downwards, or the lock can be released by turning upwards.

[0043] The inner plug cover a1 is disposed on the mouth of the kettle body 1 at the top through the lower cover 3. The lower cover 3 and the kettle body 1 are removably connected by threads, etc. A water spout 301 is formed on the lower cover 3. The inside of the kettle body 1 is communicated with the external space through the water spout 301. Users can drink the beverage in the kettle body 1 through the water spout 301. When the upper cover 2 is closed, the water spout 301 is closed by the upper cover 2 to prevent the beverage in the kettle body 1 from leaking out through the water spout 301.

[0044] As Figure 1 、 Figure 2 and Figure 5 shown, an elastic cover structure a2 is provided between the upper cover 2 and the lower cover 3. The elastic cover structure a2 includes an unlocking control member 4, a lower guide block 302, and an elastic body 7. The elastic body 7 is disposed at the rotation connection position of the upper cover 2 and the lower cover 3. The elastic body 7 is an essential component of the elastic cover structure. When the upper cover 2 is closed on the lower cover 3, the elastic body 7 is compressed and deformed by the pressure of the upper cover 2. When the upper cover 2 is turned upwards, the elastic body 7 recovers its deformation. The elastic force generated by the recovery of the deformation provides power for the upper cover 2 to turn over, prompting it to quickly turn to the in-place position. The elastic body 7 can be a rubber block, a torsion spring 701, an elastic rope, etc., as long as it can achieve the above actions.

[0045] As Figure 1 and Figure 3 shown, the unlocking control member 4 is disposed between the upper cover 2 and the lower cover 3, so that the unlocking control member 4 is opposite to the lower cover, and the unlocking control member 4 is rotatably connected to the upper cover 2. When the upper cover 2 and the lower cover 3 are closed and locked, the unlocking control member 4 is located at the initial static position.

[0046] As Figure 1 、 Figure 2 andFigure 5 As shown in the figure, the lower guide block 302 is formed on the lower cover 3. Specifically, the lower guide block 302 is located on the outer wall of the water nozzle 301. When the unlocking control member 4 rotates away from the initial position, it can be lifted upward by the lower guide block 302 on the lower cover 3. The upper cover 2 is synchronously lifted with the unlocking control member 4, forming a gap between the upper cover 2 and the lower cover 3, so that external air enters, realizing the air pressure balance inside and outside the kettle body 1. Then, under the elastic force of the elastic body 7, the upper cover 2 quickly flips in place to realize unlocking. After the unlocking control member 4 rotates back to its original position, it prepares for the next unlocking action of the upper cover 2 and the lower cover 3.

[0047] As Figures 1 to 5 shown in the figure, the elastic cover structure a2 further includes an upper guide block 401. The upper guide block 401 is formed on the unlocking control member 4. The lower guide block 302 is located on the rotation path of the unlocking control member 4. Therefore, when the unlocking control member 4 rotates, the upper guide block 401 will pass by the lower guide block 302. When the unlocking control member 4 rotates away from the initial position, the upper guide block 401 can be lifted upward by the lower guide block 302 by a certain distance, and the unlocking control member 4 is synchronously lifted, thereby driving the upper cover 2 to separate from the lower cover 3 to realize unlocking. The above settings utilize the mechanical guidance of the lower guide block 302 to the upper guide block 401, so that when the upper cover 2 needs to be unlocked from the lower cover 3, it can overcome the influence of the negative pressure inside the kettle body 1, significantly improving the unlocking success rate and preventing the failure of the elastic cover structure.

[0048] As Figures 6 to 8 and Figure 10 and Figure 11 shown in the figure, when the unlocking control member 4 rotates, the upper guide block 401 will come into contact and cooperate with the lower guide block 302. At this time, the mating surface formed by the upper guide block 401 and the lower guide block 302 is an inclined surface or a curved surface, and the height of this mating surface increases from the initial position of the unlocking control member 4 in the direction of leaving the initial position. It can be understood that when the unlocking control member 4 rotates away from the initial position and the upper guide block 401 comes into contact with the lower guide block 302, as the rotation action continues, the height of the upper guide block 401 will gradually increase, driving the unlocking control member 4 to be lifted upward, thereby driving the upper cover 2 to separate from the lower cover 3, enabling the upper cover 2 to overcome the influence of the negative pressure inside the kettle body 1 to realize unlocking. At the same time, a certain damping effect can also be generated during this process, providing tactile feedback for the user to judge whether the unlocking control member 4 has rotated in place, and also reducing the possibility of the unlocking control member 4 rotating under the action of an accidental force, ensuring that the upper cover 2 is firmly locked with the lower cover 3 when the user does not need to perform a drinking activity.

[0049] As Figure 1 、 Figure 2 and Figure 5As shown, the flip - cover structure a2 further includes a stop block 303. The stop block 303 is formed on the lower cover 3 and is also located on the rotation path of the upper guide block 401. Thus, when the upper guide block 401 rotates with the unlocking control member 4, it will also pass through the stop block 303. A stop channel 304 is formed below the stop block 303, and the upper guide block 401 is embedded in the stop channel 304. When the upper guide block 401 is embedded in the stop channel 304, the unlocking control member 4 reaches its initial position. After fitting, the upper stop block 303 will restrict the lifting of the upper guide block 401, and correspondingly restrict the upward movement of the unlocking control member 4, thereby restricting the flipping of the upper cover 2 and achieving the locking of the upper cover 2, improving the stability when the upper cover 2 and the lower cover 3 are closed.

[0050] As Figure 1 and Figure 5 shown, the water nozzle 301 includes a direct - drinking port 301a and a straw port 301b. The straw port 301b is used for drinking after inserting a straw, which can more conveniently control the drinking flow rate. The direct - drinking port 301a is suitable for quick drinking. Users can choose to use the straw port 301b or the direct - drinking port 301a to drink the beverage in the kettle body 1 according to their own preferences and needs, meeting the usage requirements in different occasions and environments.

[0051] As Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, the flip - cover structure a2 further includes a lining member 202. The lining member 202 is connected to the upper cover 3 and is located at the lower end of the upper cover 2, that is, the end close to the lower cover 3. A fitting groove 403 is formed on the unlocking control member 4. The fitting groove 403 faces the lining member 202 and has a matching shape. The lining member 202 is embedded in the fitting groove 403. To prevent the unlocking control member 4 from falling, a stepped position 403a is formed in the fitting groove 403 of the unlocking control member 4, and the lining member 202 is embedded in the stepped position 403a, thereby supporting the unlocking control member 4. The shape of the mating surface between the unlocking control member 4 and the lining member 202 is circular, so that with the lining member 202 as the rotation axis, the unlocking control member 4 is rotatably connected to the upper cover 3.

[0052] As Figure 2 and Figure 7 shown, the flip - cover structure a2 further includes a tension spring 5. The tension spring 5 is arranged between the lining member 202 and the unlocking control member 4. Both ends of the tension spring 5 are respectively connected to the lining member 202 and the unlocking control member 4. When the unlocking control member 4 rotates away from its initial position, the tension spring 5 stretches and deforms to generate elastic potential energy, providing power for the subsequent automatic reset of the unlocking control member 4.

[0053] As Figure 4 、 Figure 6 and Figure 7As shown, a limiting groove 403b is formed in the mating groove 403, and a limiting block 202a is formed on the inner lining member 202. The limiting block 202a is slidably connected to the limiting groove 403b. When the unlocking control member 4 rotates, the limiting block 202a slides synchronously along the limiting groove 403b. The functions of the limiting groove 403b and the mating limiting block 202a are similar to those of the following guide groove 201 and the dial 402. The guide groove 201 and the dial 402, as well as the limiting groove 403b and the limiting block 202a, form two groups of internal and external limits for the unlocking control member 4, jointly restricting the rotation amplitude of the unlocking control member 4.

[0054] As Figure 1 , Figure 3 and Figure 4 shown, a dial 402 is formed on the unlocking control member 4, and a guide groove 201 is formed in the upper cover 2. The guide groove 201 is a through groove that penetrates the inner and outer walls of the upper cover. The dial 402 passes through the guide groove 201 and extends into the external space for the user to control. The user indirectly controls the unlocking control member by applying control to the dial 402. The dial 402 is slidably mated with the guide groove 201. The direction of the guide groove 201 coincides with a section of the rotation path of the unlocking control member. Thus, when the dial 402 slides along the guide groove 201, the guide groove 201 can provide guidance for the rotation of the unlocking control member 4, and at the same time, the guide groove 201 also restricts the sliding range of the dial 402, thereby restricting the rotation amplitude of the unlocking control member 4 and preventing over-rotation. It should be noted that when the outer kettle lid 6 is not removed, the entire inner plug lid a1 is completely covered. At this time, it is possible to prevent the dial 402 of the unlocking control member 4 from being exposed outward and causing misoperation, effectively preventing the upper cover 2 from being accidentally opened when the user does not need to drink.

[0055] As Figure 11 shown, the elastic body 7 is a torsion spring 701. The two ends of the torsion spring 701 are respectively connected to the upper cover 2 and the lower cover 3 of the inner plug lid a1. When the upper cover 2 is closed on the lower cover 3, the torsion spring 701 is compressed and deformed under the pressure of the upper cover 2. When the upper cover 2 is turned upward, the torsion spring 701 restores its deformation, and provides power for the upper cover 2 to turn over through the elastic force of the restored deformation, prompting it to quickly turn into place.

[0056] As Figures 1 to 3 and Figure 8 shown, the upper cover 2 also has a water sealing plug 203. The water sealing plug 203 faces the water nozzle 301. When the upper cover 2 and the lower cover 3 are closed, the water sealing plug 203 seals the water nozzle 301. The water sealing plug 203 is made of silica gel or other elastic materials. The water sealing plug 203 undergoes elastic deformation under the pressure of the upper cover 2, and then forms an interference fit with the water nozzle 301, enabling the handle kettle of the present invention to have better sealing performance and preventing the beverage in the kettle from leaking out of the water nozzle 301.

[0057] Furthermore, there are two sets of corresponding upper guide blocks 401 and lower guide blocks 302. Through the two sets of corresponding upper guide blocks 401 and lower guide blocks 302, when the upper guide block 401 passes through the lower guide block 302 during the rotation of the unlocking control member 4, the lower guide block 302 can smoothly push up the unlocking control member 4 and the upper cover 2, thereby providing a smoother lid popping-up effect.

[0058] Furthermore, there are two sets of stoppers 303 corresponding to the upper guide blocks 401 and lower guide blocks 302. When the upper cover 2 is closed with the lower cover 3, the unlocking control member 4 is in the initial position. At this time, the upper guide block 401 is embedded in the stopper channel 304 below the corresponding stopper 303 and is simultaneously limited by the upper stopper 303. At this time, two fixed points are formed between the unlocking control member 4 and the lower cover 3, and the unlocking control member 4 and the upper cover 2 are more firmly closed with the lower cover 3 by using two-point positioning.

[0059] As Figures 9 to 13 shown, the present utility model also relates to a handle kettle configured with the above-mentioned inner plug lid. The handle kettle further includes a kettle body, and the inner plug lid a1 is provided inside the top of the kettle body 1.

[0060] As Figure 9 、 Figure 10 、 Figure 12 and Figure 13 shown, an outer kettle lid 6 is provided on the upper cover of the inner plug lid a1. More specifically, the outer kettle lid 6 is detachably covered on the inner plug lid a1 to seal the inner plug lid. The detachable manner between the outer kettle lid 6 and the inner plug lid a1 can be a direct insertion connection or the like, without special limitation. In addition to being used as a lid body, the outer kettle lid 6 can also be used as a drinking container to hold the beverage in the kettle body 1 when the user needs to drink.

[0061] As Figure 9 、 Figure 10 、 Figure 12 and Figure 13 shown, the handle kettle of the present utility model further includes a handle 8. The handle 8 is provided on the kettle body 1. The handle 8 provides more diverse storage and carrying methods for users, such as being able to be stored and carried by lifting, hanging, etc., to meet the usage requirements in different scenarios.

[0062] Combined with Figures 1 to 13, when the handle kettle of the present utility model is in use, first remove the outer kettle lid 6 covering the inner plug lid a1, so that the upper lid 2 and the lower lid 3 of the inner plug lid a1, as well as the guide groove 201 on the upper lid 2 and the unlocking control member 4 flap 402 penetrating through the guide groove 201 are exposed to view. Then control the flap 402 to slide along the guide groove 201, so that the unlocking control member 4 rotates away from the initial position. At the same time, the limiting block 202a of the inner lining member 202 of the upper lid 2 moves in the limiting groove 403b of the unlocking control member 4. During the process of the unlocking control member 4 departing from the initial position, the upper guide block 401 passes through the lower guide block 302. Since the mating surface with the lower guide block 302 is an inclined surface or an arc surface, the height of the upper guide block 401 can be gradually lifted under the guidance of the lower guide block 302 during sliding, and the unlocking control member 4 is driven to move upward relative to the lower lid 3 by a certain distance. At this time, the upper lid 2 can be separated from the lower lid, and the elastic force of the torsion spring 7 is used to promote the upper lid 2 to quickly flip in place to achieve unlocking. Especially when a negative pressure is formed in the kettle body 1, it can effectively overcome the influence of the negative pressure in the kettle body 1 on the unlocking of the upper lid 2. After that, the user can choose to insert a straw into the straw port 301b of the water spout 301 to drink the beverage in the kettle body 1, or directly drink through the direct drinking port 301a.

[0063] The above embodiments and the descriptions in the specification only illustrate the principles and the best embodiments of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
