Detailed Description

Referring to fig. 1~4, the utility model relates to a waterproof type rotary button includes a base section of thick bamboo 1, and the rotatory cooperation of rotating member 2 is installed at a base section of thick bamboo 1 top, and the activity of pressing member 3 is inserted in rotating member 2, installs circuit board 4 in the cavity of a base section of thick bamboo 1, installs photoelectric sensing device subassembly 4.1 and button switch 4.2 on the circuit board 4, photoelectric sensing device subassembly 4.1 includes the mount pad of "concave" shape structure, and a pair of photoelectric sensing ware is installed to the both sides of the recess of mount pad, and the inner circle of rotating member 2 extends to the cavity of a base section of thick bamboo 1 and is provided with many induction bars 2.1, and induction bar 2.1 is located photoelectric sensing device subassembly 4.1's spill induction tank, surveys the quantity of induction bar 2.1 through photoelectric sensing device subassembly 4.1 in the spill induction tank to know the gear that rotary button rotated the selection. When the pressing part 3 is pressed downwards, the pressing part 3.1 at the bottom of the pressing part 3 triggers the button switch 4.2 to realize control.

Because during the use, can't carry out the tight fit between rotating member 2 and the pressing part 3, otherwise will influence rotating member 2's rotation and control and pressing part 3's pushing down operation, consequently there is clearance fit inevitable between rotating member 2 and the pressing part 3, inevitable has water to enter into the cavity of base section of thick bamboo 1 via this clearance, consequently need carry out waterproof design to the circuit board in the cavity and protect.

Referring to fig. 1 and 2, the waterproof design of this patent is realized based on the above conventional rotary button, at this moment, the waterproof gum cover 5 covers on the circuit board 4, and the peripheral outer edge of the waterproof gum cover 5 extends downwards to between the inner walls of the circuit board 4 and the base cylinder 1, so that the waterproof gum cover 5 can block rainwater entering the base cylinder 1, and the rainwater cannot continuously contact with the circuit board 4 downwards, and the waterproof gum cover 5 is made of rubber with excellent flexibility, silica gel and other materials, and the thickness of the peripheral downward extending section of the waterproof gum cover 5 is smaller than the gap between the circuit board 4 and the inner wall of the base cylinder 1, thereby forming a tight waterproof fit.

Referring to fig. 2, in particular: the circuit board 4 and the lower layer circuit board 6 are connected through pins and the like to form an integral circuit board structure, the lower layer circuit board 6 is fixedly installed on the base 7 through bolts, and the base 7 is embedded in the base barrel 1. During assembly, after the lower-layer circuit board 6 is assembled on the base 7, the circuit board 4 is inserted and installed, then the waterproof rubber sleeve 5 covers the circuit board 4, and the extension section of the waterproof rubber sleeve 5 downwards shields the circuit board 4 and the lower-layer circuit board 6; the assembled whole is then inserted from the bottom of the base cartridge 1 upwards into the cavity of the base cartridge 1, thereby ensuring that the waterproof glue cover 5 fits tightly between the circuit board 4 and the base cartridge 1.

See fig. 2~4, specifically: the waterproof rubber sleeve 5 is made of transparent flexible materials, the waterproof rubber sleeve 5 is arranged in a protruding mode at the mounting seat of the photoelectric sensor component 4.1, and an avoiding groove 5.1 formed by downward sinking of the protruding position is embedded in a concave sensing groove of the mounting seat of the photoelectric sensor component 4.1; therefore, the induction rod 2.1 can be inserted into the avoiding groove 5.1 without obstacles, and the gear induction function of the induction rod is not influenced.
