CN211632902U - Household high-capacity efficient thermos bottle - Google Patents

Abstract

The utility model provides a household high-capacity high-efficiency thermos bottle, which structurally comprises a bottle cap, a bottle body, a liner and a bottle plug, wherein the liner is arranged inside the bottle body, the bottle plug is arranged at the liner opening at the top of the liner, and the bottle cap is arranged at the top of the bottle body; the method is characterized in that: the inner side of the bottle liner opening is provided with an internal thread, the outer surface of the bottle plug is provided with an external thread, and the internal thread and the external thread are mutually closely matched, so that the bottle plug cannot be flushed away by high-temperature gas in the bottle. In addition, the bottle plug can be compressed tightly by arranging the elastic pressing piece inside the bottle cap, so that the heat preservation and sealing performance of the vacuum bottle are effectively improved.

Description

A household large-capacity high-efficiency thermos bottle

technical field

The utility model relates to a household large-capacity high-efficiency thermos bottle, which belongs to the technical field of daily necessities.

Background technique

Most of the current thermos bottles on the market use cork stoppers. After the cork stopper is wet and expanded, it is stuck in the bottle gallbladder mouth for sealing and heat preservation. However, after long-term use, the bottle stopper is easily damaged and shrinks, resulting in the gap between the bottle stopper and the bottle gallbladder mouth. There is a gap between them, and the sealing effect is reduced; at the same time, the bottle mouth of the existing thermos is designed to be smooth, and the bottle stopper cannot be well fixed on the bottle mouth, especially when the temperature of the water is very high, the bottle stopper is very easy to be damaged The water vapor is flushed out, and the thermal insulation effect is extremely poor.

SUMMARY OF THE INVENTION

The purpose of the utility model is to solve the problems existing in the structure of the above-mentioned existing thermos, and to propose a household large-capacity and high-efficiency thermos with good sealing and thermal insulation effects.

The technical solution of the utility model: a household large-capacity high-efficiency thermos bottle, the structure of which includes a bottle cap, a bottle body, a bottle liner and a bottle stopper, wherein the bottle liner is installed inside the bottle body, and the bottle stopper is installed on the bottle on the top of the bottle liner. The gallbladder mouth and the bottle cap are arranged on the top of the bottle body; it is characterized in that: the inner side of the bottle gallbladder mouth is provided with an inner thread, and the outer surface of the bottle stopper is provided with an outer thread, and the two are closely matched with each other to ensure that the bottle stopper does not It will be flushed out by the gas in the bottle.

The top of the bottle stopper may or may not be provided with a convex ring; the convex ring may be movable or fixed.

The inside of the bottle cap can also be provided with an elastic lower pressure piece, the bottom of the lower pressure piece is in close contact with the top of the bottle stopper, and the bottle stopper will not leak air through the pressure of the downward pressure piece.

The advantages of the utility model:

1) By arranging matching threads on the inside of the bottle gallbladder mouth and the outside of the bottle cork, the bottle gallbladder mouth and the bottle cork are tightly connected and will not be flushed out by high temperature gas, which effectively improves the thermal insulation performance of the thermos;

2) By arranging an elastic lower pressure piece inside the bottle cap, and by tightening the bottle cap, the elastic lower pressure piece inside the bottle cap presses the bottle stopper tightly to further enhance the sealing performance.

Description of drawings

Accompanying drawing 1 is a schematic diagram of an embodiment of the utility model using a screw stopper for a household large-capacity and high-efficiency thermos bottle.

Figure 2 is a schematic diagram of an embodiment of a household large-capacity high-efficiency thermos bottle with a lower pressing piece of the present invention.

Detailed ways

The technical solutions of the present utility model are further described below according to the accompanying drawings.

As shown in Figure 1, a household large-capacity high-efficiency thermos includes a bottle cap, a bottle body, a bottle bladder and a bottle stopper, wherein the bottle bladder is installed inside the bottle body, and the bottle stopper is installed at the bottle bladder opening on the top of the bottle bladder. The bottle cap is arranged on the top of the bottle body; the inner side of the bottle gall opening is provided with an inner thread, and the outer surface of the bottle stopper is provided with an outer thread, and the two cooperate with each other.

The top of the bottle stopper is provided with a convex ring, and when in use, the bottle stopper can be taken out by hooking the convex ring and rotating, which is convenient to use; it is also possible to directly tighten the bottle stopper by hand without the convex ring. The bottle cap and the top of the bottle body are connected by threads to ensure the relative closure of the inner space of the bottle cap.

As shown in Figure 2, the inside of the bottle cap is equipped with an elastic lower pressure piece. When the bottle cap is tightened, a certain pressure is generated on the bottle stopper, so that the bottle stopper will not leak air. Prevent the bottle stopper from loosening or falling off due to the pressure of high-temperature steam in the bottle to ensure effective sealing of the inner container.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. The equivalent replacement or modification of the new technical solution and its inventive concept shall be included within the protection scope of the present invention.
