Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1, the utility model relates to a smoke machine capable of controlling a switch by a magnet, which comprises an organic box 1; the bottom surface of the case 1 is provided with a smoke inlet; the bottom of the case 1 is hinged with a glass door plate 5 for sealing a smoke inlet; an electric push rod for driving the glass door plate 5 to turn over is arranged in the case 1; a filter screen 3 is fixed on the smoke inlet;
a permanent magnet 4 is fixed on the glass door plate 5; a normally closed magnetic reed switch 2 is fixed in the case 1;
the normally closed reed switch 2 is not substantially different from the prior art and is not described in detail; when the glass door plate 5 is closed at the smoke inlet, the magnet is close to the normally closed magnetic reed switch 2, the normally closed magnetic reed switch 2 breaks the circuit, the smoke exhausting circuit of the whole smoke machine is powered off, and the smoke machine is in a dormant state;
