Description

Waterproof dust-proof smoke machine controller Technical Field The utility model relates to the technical field of kitchen equipment, in particular to a waterproof and dust-proof smoke machine controller. Background The gap between the key cap and the control shell of the conventional range hood is easy to enable oil smoke, water vapor and dust to enter the control switch in the long-term use process, so that not only is the movable space of the key cap blocked, but also the switch is malfunctioning, and meanwhile, the oil smoke, the water vapor and the dust entering the shell can erode a circuit board, so that the circuit board is damaged, and the service life of the control switch is very easy to shorten. Disclosure of utility model The utility model aims to solve the problems in the background art, and provides a waterproof and dust-proof smoke machine controller. The utility model adopts the following technical scheme for realizing the purposes: The utility model provides a smoke machine controller of waterproof dust proof, includes the casing, sets up at the panel of casing port and sets up the circuit board in the casing, the top surface subsides of circuit board is equipped with the switch button, the top of switch button is equipped with the button cap, the top of button cap runs through the panel, be equipped with the elastic sheath of cover in the switch button outside between panel and the circuit board, the outside of button cap bottom is formed with annular guide table, be formed with annular isolation chamber in the elastic sheath, the elastic sheath top in isolation chamber outside is inwards turned over and is formed with the spacer that covers in the guide table top, the hole of spacer and the outer wall cooperation of button cap, the elastic sheath of isolation intracavity side is formed with the resilience piece, the top of returning the shell fragment is contradicted the bottom surface of guide table. Further, a positioning groove corresponding to the switch key is formed in the bottom surface of the panel, the top end of the elastic sheath stretches into the positioning groove, and the top surface of the isolation sheet abuts against the inner top surface of the positioning groove. Further, the inner holes of the isolating sheets and the inner holes of the isolating sheets are in contact with the outer wall of the key cap. Further, the inner holes of the isolating sheets and the inner holes of the isolating sheets are not contacted with the outer wall of the key cap.
