Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermos cup technology, specifically a thermos cup with a press-type lid. Background Technology
[0002] The design of thermos flasks is primarily based on the principle of vacuum insulation. Through a double-layered stainless steel structure with a vacuum layer in between, the exchange of heat between the inside and outside is effectively prevented, allowing the liquid inside to maintain its temperature for a longer period.
[0003] Traditional thermos cups typically use a screw-on lid to achieve a sealing effect, ensuring that beverages can be effectively kept warm during the insulation process and preventing liquid leakage, thus providing users with a convenient carrying and usage experience.
[0004] When the temperature is kept warm for a long time, the water temperature inside the cup gradually decreases as the insulation time extends. This temperature change is accompanied by a change in the state of water vapor. When the high-temperature water vapor encounters the cold, it will liquefy, changing from a gaseous state to a liquid state. This reduces the water vapor content inside the thermos cup, which in turn causes the internal air pressure to gradually decrease. At this time, when the user tries to open the lid, they will encounter greater resistance, increasing the difficulty of opening.
[0005] In view of the above, this application is hereby submitted. Utility Model Content
[0006] The purpose of this invention is to provide a thermos cup with a press-type lid to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model provides a thermos cup with a press-type lid, including a lid, a pressing post slidably installed on the inner wall of the lid, a hollow post rotatably installed on the inner wall of the pressing post, a sealing plate fixedly installed at the bottom of the hollow post, a venting groove opened at the bottom of the hollow post, a venting hole opened at the top of the pressing post, a sliding groove opened on the outer wall of the pressing post, a locking post slidably installed on the inner wall of the sliding groove, and the end of the locking post fixedly installed on the inner wall of the lid, and the pressing post communicating with the hollow post when rotating.
[0008] Furthermore, a limiting groove is provided at the bottom of the supporting plate, and a support rod is slidably installed on the inner wall of the limiting groove. The bottom end of the support rod is fixedly connected to the outer wall of the spring. The top of the pressing column is made of heat-insulating material, and an integrally formed anti-slip texture is provided on the surface of the pressing column.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a thermos cup with a press-type lid, including a lid 1, a pressing post 4 slidably installed on the inner wall of the lid 1, a hollow post 14 fixedly installed on the inner wall of the pressing post 4, and a sealing plate 16 fixedly installed at the bottom of the post 4. Under normal conditions, the post 14 tightly fits the bottom of the sealing sleeve 2, effectively preventing heat loss and liquid leakage. At the same time, a venting groove 15 is opened at the bottom of the hollow post 14, which, together with the venting hole 17 opened at the top of the pressing post 4, forms an effective pressure relief channel. When the user presses the pressing post 4, the pressure inside the thermos cup 18 can be slowly released through this channel, avoiding the problem of the lid 1 being difficult to open due to excessive internal pressure.
[0021] Please see Figure 2 , Figure 5 This utility model provides a technical solution: a thermos cup with a press-type lid, including a tapered column 7 fixedly installed at the bottom of the press column 4, the outer wall of the tapered column 7 abutting against the support plate 8. When the user presses down the press column 4 each time, the tapered column 7 will support the support plate 8, thereby causing the rubber ring 9 sleeved on the outer wall of the support plate 8 to expand. Utilizing the elastic properties of the rubber ring 9, it can effectively support the sealing sleeve 2 fixedly connected to its outer wall, ensuring that the sealing sleeve 2 can tightly fit the inner wall of the thermos cup 18, thereby enhancing the sealing performance of the thermos cup 18.
[0022] Furthermore, the gap between the supporting plates 8 after they are expanded is only about 0.5cm, so the rubber ring 9 will fit against the inner wall of the thermos cup 18 after expansion, thus effectively preventing heat loss and liquid leakage.
[0023] Please see Figure 3 This utility model provides a technical solution: a thermos cup with a press-type lid, including a conical column 7 at the bottom of the press column 4 that not only abuts against the support plate 8, but also has a spring 13 fixed at its bottom. The bottom of the spring 13 is further fixed with a fixing ring 12. The inside of the fixing ring 12 is slidably connected to the hollow column 14. In order to guide and control the movement of the press column 4, a groove 5 is opened on the outer wall of the press column 4. A locking column 6 is slidably installed on the inner wall of the groove 5. The end of the locking column 6 is fixedly installed on the inner wall of the lid 1. The locking column 6 effectively locks the press column 4, so that the press column 4 can be released or locked as expected each time it is pressed.
[0024] Furthermore, the combination of spring 13 and retaining ring 12 provides the necessary elasticity and support, ensuring that the pressing column 4 can be smoothly reset after being pressed. The sliding fit between the slide groove 5 and the locking column 6 not only ensures that the pressing column 4 can move up and down smoothly, but also effectively prevents it from moving excessively or deviating from the track, thereby improving the stability and durability of the entire structure.
[0025] Please see Figure 4 This utility model provides a technical solution: a thermos cup with a press-type lid, including a support plate 8 with a limiting groove 11 at the bottom, so that the inner wall of the limiting groove 11 can slide to install a support rod 10, and the bottom end of the support rod 10 is fixedly connected to the outer wall of the spring 13, ensuring that when the support plate 8 is supported by the conical column 7, it can move smoothly and in a controlled manner, thereby preventing the support plate 8 from deviating or shaking during the movement.
[0026] Please see Figure 5 This utility model provides a technical solution: a thermos cup with a press-type lid, including a sealing plate 16 made of rubber. The rubber material, with its good elasticity and sealing performance, can fit tightly and effectively against the bottom of the sealing sleeve 2, thereby effectively preventing heat loss and liquid leakage. The rubber surface is also cleverly provided with an integrally formed anti-slip texture, which enhances the friction between the sealing plate 16 and the sealing sleeve 2, ensuring the tightness and stability of the seal.
[0027] Please see Figure 2 This utility model provides a technical solution: a thermos cup with a press-type lid, including a heat-insulating material on the top of the press column 4 that can effectively isolate heat transfer, making it safer and more comfortable for users to operate the press column 4. The one-piece molded anti-slip texture on the surface of the press column 4 enhances the stability of the user's operation. The anti-slip texture can increase the friction between the user's fingers and the press column 4, preventing misoperation or the press column 4 from falling off due to slipping during the pressing process.
[0028] Please see Figure 1 , Figure 6 This utility model provides a technical solution: a thermos cup with a press-type lid, including a thermos cup 18 slidably disposed at the bottom of the lid 1. In order to ensure sealing performance, a sealing ring 3 is also snapped into the bottom of the lid 1. The outer wall of the sealing ring 3 abuts against the top of the thermos cup 18, effectively preventing liquid from leaking from the gap between the lid 1 and the cup body.
[0029] Furthermore, since the sealing ring 3 is snapped onto the bottom of the lid 1, the user can easily remove it for cleaning or replacement, simplifying the cleaning and maintenance process of the thermos 18, which not only improves the user experience but also extends the product's lifespan.
[0030] Working principle: When the user presses down on the pressing column 4, the conical column 7 will support the supporting plate 8, which will cause the rubber ring 9 fitted on the outer wall of the supporting plate 8 to expand. The rubber ring 9 utilizes its elastic properties to effectively support the sealing sleeve 2 fixedly connected to its outer wall, ensuring that the sealing sleeve 2 can fit tightly against the inner wall of the thermos cup 18. At the same time, the pressing column 4 is slidably installed on the inner wall of the cup lid 1. The bottom of the hollow column 14 fixedly installed inside the pressing column 4 is connected to the sealing plate 16. Under normal conditions, it fits tightly against the bottom of the sealing sleeve 2, effectively preventing heat loss and liquid leakage. At the same time, the vent groove 15 opened at the bottom of the hollow column 14 and the vent hole 17 opened at the top of the pressing column 4 combine to form an effective pressure relief channel. When the user presses the pressing column 4, the pressure inside the thermos cup 18 can be slightly released through this channel.
