Abstract

The utility model discloses a thermos bottle stopper. The middle part of the bottle stopper body is provided with an up and down through hole, the lower end of the hole is provided with an air channel, the upper end of which is an overflow channel, and the upper part of the overflow channel is a notch. The air channel, overflow channel and the center of the notch are on the same central axis, and the plug is arranged in the air channel. The button is fixedly connected, the tension spring is set on the connecting rod, its lower end is fixedly connected with the plug, its upper end is fixed on the side wall of the overflow channel, and an oblique cone that fits the plug is arranged between the air channel and the overflow channel On the surface, when the extension spring exerts a pulling force on the plug, the plug will automatically be blocked on the inclined cone surface between the air channel and the overflow channel. The utility model has a simple structure and an ingenious design. Because the plug is under the action of the extension spring, the air pressure inside the bottle is always equal to the air pressure outside the bottle.

Description

A thermos bottle stopper

technical field

The utility model relates to the field of daily life appliances, in particular to a thermos bottle stopper. the

Background technique

In the process of daily use of thermos bottles, there is often a phenomenon that the cork cannot be pulled out. If it is pulled out forcibly, the hot water in the water bottle will splash out if you are not careful, which will cause burns. This is due to the current Common bottle stoppers are mostly made of wooden solid structures, and the air in the bottle is caused by the contraction of the gas inside after the temperature drops. the

Contents of the invention

The purpose of the utility model is to provide a thermos bottle stopper, which can effectively solve the problems existing in the background technology. the

In order to solve the problems existing in the background technology, it includes a bottle stopper body, the middle part of the bottle stopper body is provided with a hole through up and down, the lower end of the hole is provided with an air channel, and the upper end is an overflow channel. It is a notch 7, and the centers of the air channel, the overflow channel and the notch 7 are on the same central axis, and the plug is arranged in the air channel. The airway is fixedly connected with the button arranged in the notch 7, the tension spring is set on the connecting rod, its lower end is fixedly connected with the plug, and its upper end is fixed on the side wall of the overflow airway, between the airway and the overflow airway There is an inclined cone surface that fits the plug. When the tension spring exerts tension on the plug, the plug will automatically be blocked on the inclined cone surface between the air channel and the overflow channel. the

The extension spring is coated with anti-rust paint. the

Due to the adoption of the above technical scheme, the utility model has the following beneficial effects: the structure is simple, the concept is ingenious, because the air pressure inside the bottle is always equal to the air pressure outside the bottle because the plug is under the action of the tension spring, it is very easy to pull out , and the plug also plays a good role in isolating the air. Even if the cork is sucked, just press the button and put in the gas to achieve the purpose of air pressure balance. the

Description of drawings

In order to illustrate the utility model more clearly, the following will briefly introduce the embodiments in conjunction with the accompanying drawings. the

Fig. 1 is a structural representation of the utility model. the

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the technical solutions in the utility model embodiment will be clearly and completely described below in conjunction with the accompanying drawings in the utility model embodiment. the

Referring to Fig. 1, this specific embodiment is realized by adopting the following technical scheme, which includes a bottle stopper body 1, the middle part of the bottle stopper body 1 is provided with a hole 2 passing through up and down, the lower end of the hole 2 is provided with an air passage, and the upper end It is an overflow channel, and the top of the overflow channel is a notch 7, and the centers of the air channel, the overflow channel and the notch 7 are on the same central axis, and the plug 3 is arranged in the air channel, and the plug 3 as a whole It is conical, and its upper end is fixedly connected with the button 5 arranged in the notch 7 through the connecting rod 4 through the overflow channel, and the extension spring 6 is set on the connecting rod 4, and its lower end is fixedly connected with the plug 3, and its upper end is fixed On the side wall of the overflow channel, between the air channel and the overflow channel, there is an oblique cone surface that fits the plug 3. When the extension spring 6 exerts a pulling force on the plug 3, the plug 3 will be automatically blocked. The inclined conical surface between the air passage and the overflow passage. the

Described extension spring 6 is coated with antirust paint. the

Due to the adoption of the above technical scheme, this specific embodiment has the following beneficial effects: simple structure, ingenious conception, because the air pressure inside the bottle is always equal to the air pressure outside the bottle due to the action of the extension spring on the plug, it is very easy to pull out when it is pulled out. It is easy, and the plug also plays a good role in isolating the air. Even if the cork is sucked, just press the button and put in the gas to achieve the purpose of air pressure balance. the

It should be noted that at last: the above embodiment is only in order to illustrate the technical scheme of the present utility model, and is not intended to limit it; Although the utility model has been described in detail with reference to the foregoing embodiment, those of ordinary skill in the art should understand that: its It is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit of the technical solutions of the various embodiments of the present invention. and range. the
