Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, when the existing air detector is used to detect formaldehyde in Mongolia, there is a lot of dust, which causes a large error in the gas detection, and when dust accumulates inside the detector, it affects the gas detection. The use efficiency of the instrument; the present invention proposes a gas detector for environmental detection

specific Embodiment approach

[0031] As a specific embodiment of the present invention, a hole cover 23 is arranged above the probe 2, and the hole cover 23 is threadedly connected with the probe 2. A silicone screw block 211 is slidably connected to the No. 1 hole 21, and one end of the silicone screw block 211 is It is firmly connected with the hole cover 23, and the other end extends into the connection between the No. 1 hole 21 and the cavity 11;

[0032] During use, when the electric motor 12 rotates, the rotating fan 13 rotates, the gas in the cavity 11 is discharged, the external air flows into the No. 1 hole 21 through the through hole 22, and the silica gel screw block 211 , when the gas enters the No. 1 hole 21, the gas contacts the silica gel screw block 211. On the one hand, when the gas enters the No. 1 hole 21, the gas rotates downward through the silica gel screw block 211. The contact area between the gas and the silica gel screw block 211 Larger, so that the silica gel screw block 211 can ...

Embodiment approach

[0035] As a specific embodiment of the present invention, the through hole 22 is a tapered hole, and the cross section of the hole where the through hole 22 communicates with the No. 1 hole 21 is relatively small. The material of the block 221 is silica gel, and each triangular block tip on the triangular block 221 is fixedly connected with an iron post 222;

[0036] When in use, when the outside air passes through the through hole 22 and enters the No. 1 hole 21, the through hole 22 is a tapered hole. The hole 21 and the tapered through hole 22, when the outside air enters the No. The cleanliness of the inside of the gas, thereby reducing the error caused by the large number of dust particles during gas detection. Through the triangular blocks 221 arranged on both sides of the through hole 22, when the gas enters the through hole 22, the wall of the triangular block 221 The contact area with the gas is improved, because the material of the triangular block 221 is silica gel,...

Abstract

The invention relates to the technical field of gas detectors, in particular to a gas detector for environment detection, which comprises an electric motor, a rotating fan, a through hole, a first hole and a silica gel spiral block, when the electric motor rotates, the rotating fan rotates, gas in a cavity is discharged, external gas flows into the first hole through the through hole, a silica gel spiral block is arranged in a first hole, when gas enters the first hole, the gas makes contact with the silica gel spiral block, the contact area of the gas and the silica gel spiral block is large, a silica gel layer on the inner wall of the first hole cleans dust particles in the gas, external gas enters the first hole and a conical through hole through the through hole, and through the triangular block strips, after the gas enters the through holes, the contact area between the walls of the triangular block strips and the gas is increased, the dust particles of the gas are adsorbed by the triangular blocks, and the cleanliness of the gas flowing into the first hole is improved.

Description

technical field [0001] The invention relates to the technical field of gas detectors, in particular to a gas detector for environmental detection. Background technique [0002] A gas detector is an instrumentation tool for gas leakage concentration detection, including: portable gas detectors, handheld gas detectors, fixed gas detectors, online gas detectors, etc., mainly using gas sensors to detect The types of gases that exist are used to determine whether there are hidden dangers in the surrounding environment. It is a commonly used detection instrument in factories, schools and construction sites. [0003] There is also a patent in the prior art about a technical solution of a gas detector for environmental detection, such as a Chinese patent with application number: CN201920752636X, which discloses a formaldehyde gas detector, including a formaldehyde detector body and a cover plate and a telescopic frame, one side of the formaldehyde detector body is provided with a d...
