Problems solved by technology

[0003] The basic structure of today's hot water bag is the bag body, bag mouth and sealing plug. Existing hot water bags are made of rubber materials, and the connecting threads in the bag body and bag mouth are integrally formed. The process and structure are simple, but because the heating method of the hot water bag is heat transfer , when the heat source in the bag is limited, its action time is also limited. When the hot water in the hot water bag is cooled, only new hot water can be added for heating

Embodiment Construction

[0015] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a bag body 1, a bag mouth 2 and a sealing plug 3, the bag body 1 is provided with an air-filling hole 4, and a one-way air intake valve 5 is installed on the air-filling hole 4; the bag body 1 is a retractable bag body; the inflation hole 4 is located at the side edge of the bag body 1 .

[0016] When using a hot water bag, inject hot water into the bag body 1, and seal the bag mouth 2 with the sealing plug 3 after reaching a certain amount, use an inflatable device to inflate the bag body 1 through the inflation hole 4, and the setting of the one-way air intake valve 5 is effective The sealing of the bag body 1 is maintained; the hot water in the bag body 1 first exchanges heat with the gas in the bag body, and then both of them dissipate heat outward together, and the heat transfer of the gas effectively prolongs the action time of the bag body 1 .

Abstract

The invention belongs to the technical field of daily heating supplies, and particularly discloses a long-acting thermal insulation hot water bag. The long-term thermal insulation hot water bag includes a bag body, a bag mouth and a sealing plug, and is characterized in that: the bag body is provided with an air-filling hole, and a one-way air intake valve is installed on the air-filling hole. The invention has the advantages of simple structure, convenient use and reasonable design, can effectively prolong the heating time of the hot water bag, save energy, and is easy to popularize.

Description

(1) Technical field [0001] The invention belongs to the technical field of daily heating supplies, and in particular relates to a long-acting thermal insulation hot water bag. (2) Background technology [0002] When a certain part of the human body catches a cold, is injured and feels uncomfortable, or has a fever and needs hot or cold compresses, hot water bags are commonly used, and normal people also use hot water bags to warm their hands in winter. Therefore, hot water bags are widely used. [0003] The basic structure of today's hot water bag is the bag body, bag mouth and sealing plug. Existing hot water bags are made of rubber materials, and the connecting threads in the bag body and bag mouth are integrally formed. The process and structure are simple, but because the heating method of the hot water bag is heat transfer , when the heat source in the bag is limited, its action time is also limited, and when the hot water in the hot water bag is cooled, only new hot wa...
