The battery box 110 is used for receiving the battery 100, the conductive member 120 is located at a first end of the battery box 110 and is used for being electrically connected with the battery 100, and the sensor 130 is located at the first end of the battery box 110 and is used for detecting the in-place insertion condition of the battery 100 when the battery 100 is inserted into the battery box 110 and is inserted in place.

In addition, the sidewall of the breather valve 400 may be provided with a groove 404, and the groove 404 is used for embedding a mounting circuit board 405. The groove 404 penetrates through the shell of the breather valve 400, the first surface of the circuit board 405 is connected to the conductive element 120 through a lead and is powered by the battery 100, and the lead led out from the second surface enters the groove 404 to be connected with the inside of the breather valve 400 and is powered by the breather valve 400, so that the output end of the breather valve 400 controls the pressure plate 402 in the diaphragm 401 to move close to or far away from the free end of the inner cylinder 227.

The application provides a ventilation equipment novel structure, simple to operate because exhaust pipe 300 is connected with output section of thick bamboo 223 and is the below of locating breather valve 400 of the form of slope downwards gradually, are favorable to the moisture in the expired gas to arrange outward.

The above embodiments are merely examples and are not intended to limit the scope of the present disclosure, and all modifications, equivalents, and flow charts using the contents of the specification and drawings of the present disclosure, which are directly or indirectly applied to other related technical fields, are included in the scope of the present disclosure.
