Description

Technical Field

[0001] This invention relates to the field of daily necessities technology, and in particular to a highly efficient heat-insulating combined vacuum hot water bottle. Background Technology

[0002] In existing technology, thermos flasks typically consist of an outer shell, an inner liner, and a cap. The inner liner is housed within the outer shell, and a cap is located at the mouth of the inner liner. To improve heat retention, the inner liner is generally made with a double-layer structure, with a vacuum chamber formed by evacuating the layer, and a reflective coating is applied to the inner side of the layer. The inner liner is usually made of glass, and the cap is often a cork stopper or a regular plastic cap. Most thermos flasks also lack a temperature measuring device. This structure has the following shortcomings: First, the cap's heat insulation effect is not ideal, allowing heat to easily dissipate from the mouth of the bottle. Furthermore, prolonged soaking of the cork can affect water quality, produce odors, or cause corrosion. Second, the outer shell only provides support and protection; it does not form a sealed fit or vacuum insulation layer with the inner liner, allowing the outer shell to still emit a significant amount of heat, resulting in poor overall heat retention. Third, the glass inner liner is easily broken, posing a safety hazard, and the silver plating process pollutes the environment. Fourth, the lack of a temperature measuring function prevents users from knowing the real-time water temperature, causing considerable inconvenience in daily life. Summary of the Invention

[0003] The purpose of this invention is to provide a highly efficient heat-insulating combined vacuum hot water bottle to solve the problems of poor heat insulation effect of the bottle cap leading to easy heat loss from the bottle mouth, easy breakage of the glass inner liner and environmental pollution caused by the silver plating process, and the inability of users to know the water temperature inside the bottle in real time.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a high-efficiency heat-insulating combined vacuum hot water bottle, comprising an outer shell, an inner liner, and a vacuum temperature-measuring bottle cap. The outer shell includes a hollow shell and a bottom cap, with the lower end of the hollow shell connected to the bottom cap. The bottom cap has a first vacuum nozzle. The inner liner is fitted inside the outer shell, with a constricted neck and a bottle opening at the top. The outer shell and inner liner are shaped and sealed together, forming a first vacuum cavity between them. The inner liner has a double-layer structure, including an inner layer and an outer layer, with a second vacuum cavity formed between the inner and outer layers. The vacuum temperature-measuring bottle cap is located on the bottle opening. The vacuum temperature measuring water bottle cap includes an inner cap shell, an outer cap shell, a third vacuum chamber, a second vacuum nozzle, and a temperature measuring module. The inner cap shell is fitted onto the bottle opening, and the outer cap shell is sealed to the inner cap shell. The third vacuum chamber is formed between the outer cap shell and the inner cap shell. The second vacuum nozzle is provided on the outer cap shell for evacuating the third vacuum chamber. The temperature measuring module is provided on the outer cap shell, and the temperature measuring module includes a temperature control probe and a temperature control display. The temperature control probe passes through the third vacuum chamber and extends into the inside of the bottle opening. The temperature control display is located on the top outer side of the outer cap shell.

[0005] Furthermore, the inner side of the second vacuum cavity is covered with a reflective film, which is applied to the inner liner by a molding process.

[0006] Furthermore, the inner liner is made of PC plastic.

[0007] Furthermore, the top of the hollow shell is connected to the bottleneck of the inner liner, and the hollow shell abuts against the cap of the vacuum temperature measuring water bottle.

[0008] Furthermore, a bracket is provided between the bottom cover and the inner liner, the bracket being used to fix the position of the inner liner inside the outer shell and to buffer impacts.

[0009] Furthermore, the empty shell is provided with a handle.

[0010] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention relates to a high-efficiency heat-insulating combined vacuum thermos flask. A first vacuum chamber is formed by the sealed outer shell and inner liner; a second vacuum chamber is formed by the double-layered structure of the inner liner; and a third vacuum chamber is formed by the sealed connection between the inner shell of the thermos flask and the outer shell of the thermos flask cap. This triple vacuum insulation system effectively blocks heat conduction paths in three directions: the bottle opening, the bottle body, and the outer shell, significantly improving the heat insulation effect. Simultaneously, a temperature measuring module is installed on the cap, with a temperature control probe extending through the third vacuum chamber to the inside of the bottle opening, enabling real-time and accurate monitoring of the water temperature inside the bottle. The temperature control display is located on the top outer side of the cap shell for easy user observation. Furthermore, the inner liner is made of PC plastic with a heat distortion temperature of 135℃ and a decomposition temperature exceeding 1000℃, making it safe, non-toxic, and not easily broken, avoiding the safety hazards associated with easily damaged glass inner liners. Additionally, a molding process is used to coat a reflective film instead of the traditional silver plating process, eliminating the environmental pollution caused by silver plating, and the process is simple and low-cost.

The outer shell 1 and the inner liner 2 are shaped accordingly. The inner liner 2 is fitted inside the outer shell 1 and is sealed to the inner liner. The bottleneck of the inner liner 2 is tapered and forms a bottle mouth 4 at the top. The vacuum temperature measuring water bottle cap 3 is provided on the bottle mouth 4.

[0019] The cavity formed by the outer shell 1 and the inner liner 2 is the first vacuum cavity 21, which has a good heat preservation effect.

[0022] Furthermore, the inner liner 2 has a double-layer structure, and the cavity between the two layers is a second vacuum cavity, which has a good heat preservation effect. Preferably, the inner side of the second vacuum cavity is covered with a reflective film 22, which can effectively reduce heat radiation loss.
