Embodiment Construction

[0015] Such as Figures 1 to 4 As shown, the negative pressure dry ice drawing tool box of the present invention comprises box body 1, case cover 5, piston exhaust pump 7 and dry ice storage room, and box body is cuboid shape, and in the box body is drawing tool storage room 2, and dry ice is arranged in the drawing tool storage room The storage room 11 is sealed and connected between the 5 surfaces of the box body. The air pump installation port and the box body are combined into a sealed whole. There is a sealing socket 3 around the upper opening of the box body. The sealing socket and the upper end opening of the box body are combined into a sealed whole body. Corresponding sealing inserts 4 are provided around the opening of the lower end of the case cover, and the sealing inserts and the opening at the lower end of the case cover are combined into a sealed whole. In order to ensure the negative pressure effect, the sealing socket, the sealing edge, and the air pump instal...

Abstract

The invention discloses a negative-pressure dry ice drawing tool box which comprises a box body, a box cover, a piston exhaust pump and a dry ice storage chamber. An upper-end opening of the box body is provided with a sealing socket, a lower-end opening of the box cover is provided with a corresponding sealing insertion edge, a drawing tool storage chamber is formed in the box body, the dry ice storage chamber is formed in the drawing tool storage chamber, and the piston exhaust pump is installed in the box body through an air pump installing opening formed in the side face of the box body. The negative-pressure dry ice drawing tool box has an air exhaust function, a part of air in the box body is exhausted to enable the inside of the airtight drawing tool storage chamber to be in a negative-pressure state. In addition, the dry ice storage chamber has function of storing dry ice and carbon dioxide gas release functions, and released carbon dioxide gas is filled into the airtight drawing tool storage chamber. Due to the fact that bacteria are difficult to survive and propagate in a negative-pressure environment and carbon dioxide gas for a long period of time, the bacterial inhibiting effect is played, bacterium breeding in drawing tool storage is avoided or decreased, and the negative-pressure dry ice drawing tool box is high in efficiency and low in cost and achieves a good drawing tool storage purpose.

Description

technical field [0001] The invention belongs to the field of storage devices for painting tools, in particular to a negative pressure dry ice painting tool box. Background technique [0002] Currently, drawing tools are usually stored in the drawing toolbox. However, when painting tools are stored in an indoor environment of normal temperature and pressure, bacteria will continue to grow. For a long time, bacteria will damage the painting tools, 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 painting tool box with simple structure, easy manufacture and easy operation, so as to avoid or reduce the breeding of bacteria in the storage of painting tools. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a negative pressure dry ice painting tool box, includi...
