Gas detector with battery fool-proof function

Abstract

The invention discloses a gas detector with a battery fool-proof function. When a battery cavity body is not provided with a battery, one end of a sliding block protrudes in the battery cavity body under an elastic effect of an elastic piece, a fool-proof boss on the sliding block is not overlapped with a pool-proof groove in a battery cover, and the battery cover cannot side slide to cover the battery cavity body and a covering board. When the battery cavity body is provided with the battery, the battery can squeeze and sliding block to enable the sliding block to overcome elasticity of the elastic piece and to move towards the direction of the covering board, so that the sliding block drives the fool-proof boss on the sliding block to move on a strip-shaped through hole. After fool-proof boss moves to a certain position, the pool-proof boss is overlapped with the fool-proof groove and enters the fool-proof groove, the battery cover side slides on the sliding groove to cover the battery cavity body and the covering board, and assembling steps of the battery are finished. Compared with the prior art, under the situation that the battery is not assembled, a user cannot cover the battery cover, so that the user is reminded of assembling the battery, and error judgment is avoided.

Description

Technical field [0001] The present invention relates to the field of detectors, and specifically refers to a gas detector with a battery foolproof function. Background technique [0002] As people's requirements for safety and health products are getting higher and higher, some toxic gas detectors will follow. At present, the CO gas detector on the market does not have a battery foolproof structure. Even if the detector is not equipped with a battery, the battery cover can be closed, so people may mistakenly think that this CO gas detector can also work normally. , And CO gas detector products without batteries cannot detect CO gas. Since CO is a colorless, odorless and toxic gas, a slight gas will harm the health of people living or working in it, and a heavy gas will cause suffocation and endanger people’s lives. Therefore, the CO gas detector needs to design a battery foolproof structure To avoid the above misjudgment. Summary of the invention [0003] In view of the above-m...
