Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Please refer to fig. 1 to 3. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

Referring to fig. 1, the present invention provides a smoke alarm with a cleaning function, including: dustcoat 5, clean mechanism 4, smoke detector body 9 and base 8, dustcoat 5 set up base 8 on, smoke detector body 9 set up dustcoat 5 inside base 8 on, clean mechanism 4 set up on the dustcoat 5 of smoke detector body 9 top, clean mechanism 4 including pressing handle 11, press and be provided with reset spring 12 between handle 11 and the dustcoat 5, press handle 11 bottom and be provided with piston 15, both sides are provided with check valve 10, check valve 10 connects intake duct 3, piston 15 below is provided with check valve 14, gas outlet 13 is connected to check valve 14 below.
