It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0025] Some embodiments of this application relate to a novel inner plug structure for a labor-saving lever switch for an insulated container, as shown in Figures 1-4, including an insulated container handle button 1, an insulated container cover 2, an elastomer 4, and an insulated container plug 6.

[0026] The insulated container lid 2 is detachably and adaptably installed above the inner plug lid 9; the insulated container handle button 1 extends from the top of the insulated container lid 2 to the top of the handle 7 on the side of the inner plug lid 9, and the insulated container handle button 1 is rotatably connected to the side of the insulated container lid 2 near the handle 7, so that the insulated container handle button 1 forms a lever switch structure; wherein, the part of the insulated container handle button 1 above the handle 7 is the power arm, and the part above the insulated container lid 2 is the resistance arm.

[0027] The insulated container stopper 6 is used to seal the opening on the inner stopper 9, and its upper side is fixedly connected to the resistance arm; the elastomer 4 is disposed between the upper part of the insulated container stopper 6 and the lower part of the insulated container cover 2.

[0028] The handle button 1 of the insulated container includes a first limit stroke position and a second limit stroke position; wherein, in the first limit stroke position (see Figure 4), the end of the power arm abuts against the surface of the handle 7, the insulated container plug 6 separates from the inner plug cover 9 and forms a water outlet space (see position b in Figure 4); in the second limit stroke position (see Figure 3), the end of the power arm leaves the surface of the handle 7, and the insulated container plug 6 is sealed to the inner plug cover 9.

[0029] The elastic body 4 is cylindrical and made of silicone, or the elastic body 4 is several springs, or other elastic components.

[0030] In some embodiments, as shown in Figures 1-4, a novel inner plug structure for a labor-saving lever switch of a thermal insulated container further includes: a thermal insulated container plug 3; the thermal insulated container plug 3 is integrally disposed on the lower side of the thermal insulated container cover 2, wherein the inner plug 9 is a groove-shaped structure with an opening at the bottom and a water outlet extending outward from the top of the side wall, the thermal insulated container plug 3 is nested inside the inner plug 9, and the outer side of the thermal insulated container plug 3 near the water outlet, the inner side of the inner plug 9, and the water outlet together form a water outlet channel.

[0031] The lower side of the insulated container stopper 3 is provided with a groove; the upper end of the elastomer 4 abuts in the groove and the lower end abuts on the upper side of the insulated container stopper 6.

[0032] The upper side of the insulated container lid 2 is provided with a strip groove, and the resistance arm of the insulated container handle button 1 is partially or entirely located in the strip groove.

[0033] A pull rod 8 is fixedly connected to the upper side of the insulated container stopper 6. The pull rod 8 passes through the insulated container cap stopper 3 and the insulated container cap 2 in sequence and is rotatably connected to the resistance arm.

[0034] In some embodiments, a novel inner plug structure for a lever switch of an insulated container further includes a sealing ring 5; the sealing ring 5 is disposed at the opening of the inner plug 9 to achieve a sealed connection between the insulated container plug 6 and the inner plug 9. The sealing ring 5 is made of silicone.

[0035] The end of the resistance arm of the handle button 1 of the insulated container extends above the water outlet; and when the handle button 1 of the insulated container is turned to the second limit stroke position, the end of the resistance arm of the handle button 1 of the insulated container can be adapted to cover the water outlet.

[0036] In some embodiments, the outlet is tightly sealed by an internal plug of the insulated container to ensure insulation performance.

[0037] In some embodiments, a sealing ring 5 is provided below the plug, and an elastomer 4 is installed above the sealing ring 5, which is securely placed in the groove of the insulated container cap 3.

[0038] In some embodiments, the insulated container lid 2 and the insulated container plug 3 are designed as an integrated unit to ensure structural stability.

[0039] In some embodiments, the sealing ring 5 is made of silicone, which has good sealing performance and good durability.

[0040] For example, in actual operation, since the insulated container button 1 and the insulated container lid 2 are connected by a hinge, simply press the insulated container handle button 1 lightly. Through the elastic force of the elastic body 4, the insulated container stopper 6 can be driven to rise and generate a distance a. At the same time, the resistance arm end of the insulated container handle button 1 generates a distance b. Thus, the outer side of the insulated container lid stopper 3 near the water outlet, the inner side of the inner stopper 9, and the water outlet together form a water outlet channel. That is, opening the stopper forms a water outlet channel, thereby realizing the water outlet function of the insulated container.

[0041] This application has at least the following beneficial effects:

[0042] 1. This application utilizes a unique stopper structure design to ensure that water does not pass through the inside of the stopper, effectively preventing the accumulation of scale and other impurities, making cleaning more convenient, and avoiding secondary water pollution, thus providing users with a healthier and safer user experience. Furthermore, the optimized structure not only reduces manufacturing and maintenance costs and improves the user experience, but also further enhances the overall performance of the insulated container, strengthening the product's market competitiveness.

[0043] 2. This application features a sealing ring at the bottom of the stopper and an elastomer installed above the sealing ring. The elastomer is securely placed in the groove of the insulated container stopper. Because the insulated container lid and the insulated container stopper are designed as a single unit, the structure is stable. In actual operation, since the insulated container button and the insulated container lid are connected by a hinge, simply pressing the insulated container handle button will cause the insulated container stopper to rise due to the elastic force of the elastomer, thereby opening the water outlet b and realizing the water dispensing function.
