Embodiment Construction

[0015] Such as Figures 1 to 4 As shown, the negative pressure dry ice book storage box of the present invention includes a box body 1, a box cover 5, a piston exhaust pump 7 and a dry ice storage room. 11. The 5 surfaces of the box are sealed and connected. The air pump installation port and the box are combined into a sealed whole. There are sealing sockets 3 around the upper opening of the box. The sealing socket and the upper opening of the box are combined into a sealed whole. The box cover Corresponding sealing inserts 4 are arranged around the opening at the lower end, and the sealing inserts are combined with the opening at the lower end of the box cover to form a sealed whole. In order to ensure the negative pressure effect, the sealing socket, the sealing edge, and the air pump installation port are made of rubber.

[0016] The piston exhaust pump is installed in the casing through the air pump installation port 9 arranged on the side of the casing. The pump body o...

Abstract

The invention discloses a negative pressure dry ice book storage box. The negative pressure dry ice book storage box comprises a box body, a box cover, a piston exhaust pump and a dry ice storage chamber. An opening in the upper end of the box body is provided with a sealing insertion opening, and an opening in the lower end of the box cover is provided with a corresponding sealing insertion edge. A book storage chamber is arranged in the box body, and the dry ice storage chamber is arranged in the book storage chamber. The piston exhaust pump is installed in the box body through an air pump installation opening formed in the side face of the box body. The negative pressure dry ice book storage box has the air pumping function, and the negative pressure state is formed in the airtight book storage chamber by pumping out part of air in the box body; meanwhile, the dry ice storage chamber has the dry ice storage and carbon dioxide gas release functions, and the book storage chamber is filled with released carbon dioxide gas; due to the fact that bacteria can not survive or breed easily if the bacteria stay in a negative pressure environment or carbon dioxide gas for a long time, the bacterium restraining effect is achieved, and bacterium breeding in book storage is avoided or reduced; and besides, the negative pressure dry ice book storage box is high in efficiency, low in cost and capable of storing books well.

Description

technical field [0001] The invention belongs to the field of book storage devices, in particular to a negative pressure dry ice book storage box. Background technique [0002] Currently, books are usually stored in bookshelves, bookcases, and bookcases. However, when books are stored in an indoor environment of normal temperature and pressure, bacteria will continue to grow. For a long time, bacteria will damage books, pollute the indoor environment, and then affect human health. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a negative pressure dry ice book storage box with simple structure, easy manufacture and easy operation, so as to avoid or reduce the breeding of bacteria in book storage. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: negative pressure dry ice book storage box, including box body, box cover, piston exhaust pump and ...
