[0002] Chemical industry is the abbreviation of "chemical technology", "chemical industry", "chemical engineering", etc. All technologies that use chemical methods to change the composition, structure or synthesize new substances belong to chemical production technology, that is, chemical technology, and the products obtained are called chemical products or chemical industrial products. At first, these products were produced in handicraft workshops, and later evolved into factories, and gradually formed a specific production industry, namely the chemical industry. Chemical engineering is a science that studies the common laws of the production process of chemical products. The relationship between humans and the chemical industry is very close. Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization.

[0003] Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials, and their chemical raw materials are further divided into different forms, such as liquid and solid.

[0030] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.

[0031] Embodiment: As Figures 1-3 shown, a safety sampler for chemical quality inspection of the present utility model includes a portable box 1. A sampling assembly 4 is fixedly installed inside the portable box 1. A strip-shaped through hole 5 is provided at the right end of the portable box 1 along the vertical direction. The right end of the sampling assembly 4 penetrates through the strip-shaped through hole 5 and extends to the right side of the portable box 1. The lower end of the portable box 1 is fixedly installed and communicated with a protection tube 7. The lower end of the protection tube 7 is open, and a sealing cover 8 is hingedly installed at the open end;

[0032] Among them, as Figure 4 shown, the sampling assembly 4 includes fixed side plates 405. There are two fixed side plates 405, which are symmetrically fixedly installed on the front and rear end faces inside the portable box 1. Slide rails 408 are provided on the mutually approaching end faces of the two fixed side plates 405 along the vertical direction. An upper mounting block 401 is installed between the tops of the two fixed side plates 405. A positioning block 403 is fixedly installed at the right end of the upper mounting block 401, and the right end of the positioning block 403 penetrates through the strip-shaped through hole 5 and extends to the outside of the portable box 1. A hollow sampling tube 404 is fixedly installed at the lower end of the upper mounting block 401, and the hollow sampling tube 404 is located directly above the protection tube 7. A connecting hose is installed on the side of the hollow sampling tube 404, and the other end of the connecting hose is fixedly communicated with the air inlet pipe of a blower 409. The blower 409 is fixedly installed on the inner wall of the portable box 1.

[0033] In this embodiment, as Figure 2 shown, a second magnet block 10 is fixedly installed in an embedded manner at the lower end of the sealing cover 8, and a first magnet block 9 is fixedly installed in an embedded manner at the left end face of the bottom of the protection tube 7. The first magnet block 9 and the second magnet block 10 are magnetically attracted to each other.
