Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiment in the utility model, under the creative work prerequisite, all other embodiments that the skilled person obtained do not make, all belong to the scope of the utility model protection.

See fig. 1-8.

To the problem that above-mentioned background art mentioned, the embodiment of the utility model provides a household electrical appliances control switch to solve above-mentioned technical problem, its technical scheme as follows:

a household appliance control switch comprises a switch main body and a button 140, wherein the upper end of the switch main body is provided with a through hole 120a, and the button 140 penetrates through the switch main body through the through hole 120 a; further comprising:

the water baffle 142 is arranged around the button 140 and positioned inside the switch main body; in this embodiment, the water guard 142 is integrally formed with the button 140.

A plurality of annular water climbing grooves 142a arranged around the button 140 are formed in the water baffle 142; through setting up a plurality of annular water channels 142a of climbing, make moisture get into the path lengthening of base 110 from the clearance between button and the apron, increase and climb the water distance, show to improve water-proof effects, prolong the switch dead time under harsh environment greatly.

A seal ring 170, wherein the seal ring 170 comprises an annular seal ring 171 which is positioned between the outer side surface of the button 140 and the inner side surface of the through hole 120a and is slidably connected, and a baffle 172 which is fixed at the lower end of the annular seal ring 171 and is arranged around the button 140; the sealing ring 170 is sleeved on the button 140 and can move up and down relative to the button 140.

The spring 180 is sleeved on the button 140 and is positioned between the baffle 172 and the water baffle 142; in this embodiment, the upper end of the spring 180 is fixedly connected to the lower end surface of the baffle 172, and the lower end of the spring 180 is fixedly connected to the upper end surface of the water baffle 142.

Under the action of the elastic force of the spring 180, the spring 180 pushes the baffle 172 and the annular sealing ring 171 upwards, so that the annular sealing ring 171 is always clamped between the outer side surface of the button 140 and the inner side surface of the through hole 120a, the sealing performance between the outer side surface of the button 140 and the inner side surface of the through hole 120a is improved, and the dustproof and waterproof effects are prevented from being deteriorated due to a gap generated by contraction or expansion of the button 140 and the through hole 120 a.

In this embodiment, the switch main body includes a base 110, a cover plate 120 covering the base 110, a metal terminal 130 disposed on the base 110, and a waterproof pad 150 and a metal elastic sheet 160 disposed below the button 140 and inside the base 110.
