Problems solved by technology
At present, the CO gas detectors on the market do not have a battery fool-proof 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 product can also work normally. , and CO gas detector products without batteries cannot detect CO gas

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 invention relates to the field of detectors, in particular to a gas detector with battery foolproof function. Background technique [0002] As people's requirements for safety and health products are getting higher and higher, some toxic gas detectors are produced. At present, the CO gas detectors on the market do not have a battery fool-proof 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 product can also work normally. , CO gas detector products without batteries cannot detect CO gas. Because CO is a colorless, odorless and poisonous gas, a slight gas will damage the health of people living or working inside, and a heavy gas will cause suffocation and endanger people's lives. Therefore, CO gas detectors need to design battery foolproof structures in order to avoid the above misjudgments. Contents of the invention [0003] In view of the...
