Description

Technical Field

[0001] This utility model belongs to the technical field of thermal cookware, specifically relating to a thermal pot that seals water when the lid is closed. Background Technology

[0002] The current device for controlling the water flow in insulated containers (thermos cups or thermos flasks, etc.) is generally a push-button switch installed at the opening of the container, such as the design patents CN 306743063 S entitled "Thermos Cup Switch" and CN 302455599 S entitled "Switch". This type of switch opens the sealing assembly by pressing the release button, thus opening the water outlet. Simultaneously, the reset switch pops up. When not in use, the reset switch needs to be manually pressed, and the release button resets, thus closing the water outlet.

[0003] However, when using a thermos, people often rush to drink after pouring the water and forget to press the shut-off button, posing a risk of leakage and scalding when carrying the thermos. Furthermore, even when stationary, forgetting to reset the button causes rapid heat loss, shortening the insulation time. Therefore, developing a thermos that seals the water when the lid is closed has become a pressing problem for those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing thermos flasks that require manual closure of the water outlet after use, which can easily lead to leakage, scalding, and temperature loss. This invention provides a thermos flask that seals the water when the lid is closed, achieving the effect of an automatic reset push-button switch when the lid is closed, thereby solving the problems of leakage, scalding, and temperature loss.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: a thermos that seals water when the lid is closed, comprising a body, a push-button switch, and a lid. The push-button switch is installed at the mouth of the body, and the upper surface of the push-button switch is provided with an unsealing button and a reset switch. The thermos is characterized in that: a first magnetic element is provided at the neck ring at the base of the mouth of the body, and a second magnetic element is provided at the lower edge of the lid that attracts the first magnetic element. When the lid is closed tightly under the action of magnetic attraction, the lid can press down the reset switch to close the water outlet channel.

[0006] Furthermore, both the first and second magnetic attractors are magnets. Alternatively, one of the first and second magnetic attractors is a magnet, and the other is an iron component (such as an iron sheet or block).

[0007] Furthermore, the first magnetic element is built into the edge of the spout of the pot body, or directly fixed to the outside of the spout edge of the pot body.

[0008] Furthermore, the second magnetic element is either built into the lower edge of the lid or directly fixed to the outside of the lower edge of the lid.

[0009] When in use, to drink water, simply open the lid, press the release button on the push-button switch to open the water outlet, pour water into the lid or other container, and drink. After drinking, there's no need to manually press the reset switch; simply close the lid. The first and second magnetic components will automatically press down the reset switch, closing the water outlet and preventing leaks, scalding, and temperature drops caused by forgetting to turn off the switch.

[0010] The advantages of this utility model compared with the prior art are: 1. Immediate water sealing upon lid closure provides excellent leak prevention: Magnetic attraction is achieved through the neck ring at the base of the spout and the lower edge of the lid. When the lid approaches the spout, the magnetic force causes it to automatically seal, pressing down the reset switch of the push-button valve. This resets the valve and, in turn, resets the release button, automatically closing the water flow. This fundamentally solves the problems of leakage, scalding, and temperature loss caused by users forgetting to turn off the valve.

[0011] 2. Simple structure and easy to implement: The core function can be achieved by simply adding two magnetic parts to the body and lid of the existing thermos. The modification is simple, does not change the main structure of the push-button switch, is low in cost, and is easy to mass-produce and upgrade existing products.

[0012] 3. Enhanced user experience: The magnetic closure makes the closing process smoother and more precise, reducing the risk of misalignment. At the same time, the "one-click closing" convenience greatly improves the overall user experience and increases user satisfaction. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] like Figures 1 to 4 As shown, this utility model discloses a thermos flask with a closed lid that seals water. It includes a body 1, a push-button switch 2, and a lid 3. The push-button switch 2 is installed at the spout of the body 1, and its upper surface has an unsealing button 21 and a reset switch 22. A first magnetic element 4 is provided at the neck ring at the base of the spout of the body 1, and a second magnetic element 5 is provided at the bottom of the lid 3, which attracts the first magnetic element 4. When the lid 3 is closed tightly under the magnetic force, the lid 3 can press down the reset switch 22, closing the water outlet.

[0020] Component preparation of this utility model: The body of the kettle has a double-layer structure. The outer layer can be made of food-grade metal or food-grade plastic. The inner liner can be made of food-grade metal or food-grade glass.

[0021] The lid 3 can be made of food-grade metal or food-grade plastic to ensure safety and hygiene.

[0022] The push-button switch 2 adopts an existing mature structure, including an unlock button 21 and a reset switch 22.

[0023] The first magnetic attractor 4 and the second magnetic attractor 5 can be made of neodymium iron boron magnets or other strongly magnetic materials. Alternatively, one of them can be a magnet and the other can be an iron object (such as an iron sheet or block).

[0024] The first magnetic component 4 is embedded in the edge of the spout of the pot body 1, or it is directly fixed to the outside of the spout of the pot body 1 with glue.

[0025] The second magnetic component 5 is embedded in the bottom of the lid 3, or it is directly fixed to the outside of the bottom edge of the lid 3 with glue.

[0026] Assembly and use of this utility model: Install the push-button switch 2 at the spout of the kettle body 1 to ensure it functions properly.

[0027] Install the first magnetic component 4 and the second magnetic component 5 at the corresponding positions on the body 1 and the lid 3, respectively.

[0028] When using: Open the lid 3, press the release button 21 of the push-button switch 2 to open the water outlet channel of the sealing component, and at the same time the reset switch 22 pops up. Pour out the water and it is ready to drink.

[0029] When closed: After drinking the water, there is no need to manually press the reset switch 22; simply close the lid 3. Under the magnetic attraction of the first magnetic component 4 and the second magnetic component 5, the lid 3 will automatically and precisely fit the spout. During the closing process, the pressure of the lid 3 will act on the pop-up reset switch 22, pressing it down and thus causing the unsealing button 21 to reset, achieving the effect of automatically closing the water outlet.

[0030] In this embodiment, the number, shape, and specific position of the magnetic components can be adjusted according to actual design requirements (the magnetic components generally adopt a ring-shaped integrated structure). As long as the design uses the magnetic principle to achieve the function of sealing water by closing the lid, it falls within the protection scope of this utility model.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
