Water bottle plug and using method thereof

Abstract

The invention discloses a water bottle plug and a using method thereof. The water bottle plug comprises a bottle plug body and a ventilation heat-preservation mechanism; a cavity I and a cavity II which penetrate through the bottle plug body are formed in the center of the bottle plug body; one end of the cavity I communicates with a vacuum bottle, and the other end of the cavity I communicates with the cavity II; the other end of the cavity II communicates with the external atmosphere; and the ventilation heat-preservation mechanism is arranged in the cavity II. The top of the bottle plug body is provided with a bottle plug upper cover for covering the cavity II, a ventilation hole is formed in the bottle plug upper cover, and the cavity II communicates with the ventilation hole. The ventilation heat-preservation mechanism comprises a baffle, a spring and a boss; the boss is arranged at the end, close to the cavity I, in the cavity II; one end of the spring is connected with the bottle plug upper cover, and the other end of the spring is connected with the baffle; and the baffle is matched with the boss. Air in a water bottle communicates with the atmosphere outside the bottle through the cavity I, the cavity II and the ventilation hole, thus balance between the air pressure in the bottle and the atmospheric pressure outside the bottle is guaranteed, and the problems that whenhot water is poured into the water bottle, the water bottle is expanded through hot air, consequently the bottle plug body is prone to jumping up, and due to the fact that the hot water is cooled andthe air pressure is lowered, the bottle plug body is difficult to pull out are solved.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a water bottle stopper and a using method thereof. Background technique [0002] Most of the traditional water bottle stoppers are frustum-shaped wood. When hot water is just poured into the water bottle, the water bottle stopper tends to pop up due to the expansion of the internal gas. When the water temperature in the water bottle decreases, the internal air pressure decreases and the water bottle stopper is easy to stop. In real life, people usually cover the water bottle after filling the water bottle with hot water. However, due to the principle of thermal expansion and contraction of the air in the bottle, the pressure inside and outside the water bottle may be unbalanced, making the water The cork is difficult to open or the bottle bursts. Just because the traditional water bottle stopper is extremely inconvenient in actual use, it is extremely impor...

Problems solved by technology

In real life, people usually cover the water bottle after filling the water bottle with hot water. However, due to the principle of thermal expansion and contraction of the air in the bottle, the pressure inside and outside the water bottle may be unbalanced, making the water The cork is difficult to open or the bottle bursts

It is precisely because the traditional water bottle stopper is extremely inconvenient in actual use, it is extremely important to transform and innovate the existing traditional water bottle stopper
