Abstract
The utility model relates to the technical field of household appliances, and particularly relates to an improved water producer-used key assembly. The improved water producer-used key assembly is used for triggering switches on a circuit board, and is characterized by comprising keys, key frames, key seats, springs and sealing rings, wherein two round through holes are arranged on the key frames; the outer side wall of the key seat is provided with a circle of convex rib; the sealing ring sleeves the key seat and abuts against the upper surface of the convex rib; the sealing ring and the key seat are arranged inside the round through hole of the key frame; the key is arranged above the key seat; the upper end of the spring sleeves the lower end of the key seat and abuts against the lower surface of the convex rib; the lower end of the spring sleeves the switch on the circuit board; and the key seat is located above the switch. The improved water producer-used key assembly is simple in structure, simple and convenient in installation and good in sealing performances.
Description
Technical field
The utility model relates to household electrical appliance technical field, specifically a kind of improved water-making machine button assembly.
Background technology
Along with social development, people more and more pay attention to healthy and safe, and present domestic running water is inevitably contaminated, and the trace element in mineral water can not meet individual difference, pure water again nonnutritive drink once in a while, therefore water-making machine is more and more come in people's life.Water-making machine can not only filter the impurity in running water, can also, by water electrolysis, greatly improve the activity of water.Water-making machine is provided with various buttons, user touches the switch on circuit board by pressing keys, general button can move, so can not ensure that circuit board is in complete hermetic state, circuit board easily damages in the time meeting water, and then affect user's normal use, there is certain limitation.
Utility model content
The utility model provides the improved water-making machine button assembly of a kind of simple in structure, simple installation, good airproof performance.
The utility model is achieved through the following technical solutions:
A kind of improved water-making machine button assembly, for touching the switch on circuit board, comprise button, press keyframe, key base, spring and sealing ring, describedly be provided with two manholes by keyframe, described key base lateral wall is provided with a circle convex tendon, described ring set is on described key base, and inconsistent with described convex tendon upper surface, described sealing ring be located at together with described key base described in by the manhole of keyframe, described button is located at described key base top, described spring upper end is sleeved on described key base lower end, and inconsistent with described convex tendon lower surface, described spring lower end is sleeved on the switch on described circuit board, described key base is positioned at described switch top.
Describedly be provided with two projections by keyframe lower surface, on described circuit board, be provided with two jacks with described projection corresponding section, described projection inserts in described jack.
Described button lower surface is provided with two symmetrical reference columns, and described key base upper surface is provided with two location holes that match with described reference column.
The beneficial effect that the utility model brings is:
In the utility model, described improved water-making machine with button assembly comprise button, by keyframe, key base, spring and sealing ring, sealing ring is set described between by keyframe and described key base, user is in the time pressing described button, described button moves up and down in by the manhole on keyframe described, described sealing ring has prevented that extraneous water from entering circuit board place from button, and then has ensured the useful life of circuit board.
