The present invention packs pcb board one 5 into and encapsulates 1 unlimited silicone rubber sleeve, cover on the pcb board and with silicon rubber then and fill the open surface of silicone rubber sleeve, make silicone rubber sleeve become an obturator, pcb board is closed in the silicone rubber sleeve fully, water, oil smoke and dust can't enter silicone rubber sleeve, and the water proof and dust proof effect is very good.
During work, the press control rear portion is connecting a block power supply plate, the button on the push-button controller, the young sheet of cooking is pushed in the bottom of button, press control is given the power panel signal, and power panel is exported corresponding signal again and given motor and lighting apparatus etc., and motor and lighting apparatus are started working; After hours, click same button again, then motor and lighting apparatus quit work.
As the further of technique scheme improved and replenish, the present invention takes following technical measures:
Above-mentioned waterproof press-button controller, be provided with a dividing plate between silicone rubber sleeve and the pcb board, the Closed End indent of silicone rubber sleeve forms a plurality of grooves, have the through hole identical on the dividing plate with the groove number, groove is positioned at through hole, the bottom of described button places in the groove and with the young sheet of pot and is used, and the bottom of button is used across silicone rubber sleeve and the young sheet of pot, and the feel during push-botton operation is good.Dividing plate forms certain altitude between PET base material and silica gel sheath, be used for placing and spacing light-emitting diode (being the LED lamp).
Above-mentioned waterproof press-button controller, the young sheet of pot is fixed on the pcb board by a PET (PETG) basement membrane, and dividing plate is bonded on the PET basement membrane by double faced adhesive tape.
Above-mentioned waterproof press-button controller, button comprises the button overcoat and places plug in the interior button of overcoat, described silicone rubber sleeve is transparent, the edge of through hole is provided with the LED lamp that is installed on the pcb board, button is installed on the housing by a leaded light circle, the top of button is exposed to outside the housing, and is convenient low with manual manipulation button and whole height.During work, the light transmission silicone rubber sleeve that the LED lamp sends comes the Show Button in running order by the luminous of leaded light circle.
Above-mentioned waterproof press-button controller, the edge of the unlimited end face of silicone rubber sleeve form a circle flanging, are used to locate pcb board.
Compared with prior art, the beneficial effect that the present invention has is as follows: the water proof and dust proof excellent performance, still can be reliable and stable after permanent the use, and long service life; The bottom of button is used across silicone rubber sleeve and the young sheet of pot, and the feel during push-botton operation is good; Button adopts and the young sheet mating reaction of pot, and the whole height of product is low.
The invention will be further described below in conjunction with specification drawings and specific embodiments.
