Abstract
The invention relates to a moisture-proof switch. A sealing protective sleeve is arranged on a switch button, so that the switch is integrally in a sealed state, and external water is prevented from entering the switch. In addition, a replaceable drying box is arranged on the switch, a drying agent is arranged in the drying box, a sealing cover for preventing external air from entering the drying box is arranged on the drying box, and the inner wall of the drying box is made from a mesh material capable of absorbing water in air in the switch under the condition of avoiding the drying agent being leaked into the switch. When failing after absorbing sufficient water, the drying agent can be replaced. The sealing cover is made of a transparent material, and the water absorption state of the drying agent can be seen.
Description
Technical field
The invention belongs to the field of switching function expansion, relate in particular to a kind of moistureproof switch.
Background technology
The electronic product overwhelming majority all requires under drying condition operation and deposits.According to statistics, the whole world has the industry manufacturing defective products more than 1/4 relevant with moist harm every year.For electronics industry, moist harm has become one of principal element that influences product quality.Switch is one of indispensable element of each household electrical appliance or light fixture basically.Generally under normal environment, switch does not need special moisture preventive measure, but for the place of high humidity and bathroom and other places, the moisture resistance of switch then is important factors.The switch humidity resistance is low, not only can influence the electrical equipment behaviour in service, also can cause because personnel casualty accidents takes place in electric leakage, therefore how to make the humidity resistance of switch be guaranteed then to be one to be worth the problem that solves.
Summary of the invention
The present invention makes moist and produces the problem of potential safety hazard in order to solve switch, and a kind of moistureproof switch is provided, and comprises Switch main body, and seal protection cover is arranged on the shift knob, makes switch integral body be in sealing state, prevents that outside moisture content from entering.
On the switch of moistureproof switch drying box is installed, drier is arranged in the drying box, drier is replaceable.The drying box inwall has the interlayer of netted lattice shape, can draw water in air part of switch inside under the situation of switch is not bled in the agent of keeping dry.
The drier of moistureproof switch adopts the lime drier, and the drying box outside has the LED lamp, after the lime drier expands fully, triggers the LED lamp switch.So that reminding user to replace drier.
Each grid area 0.49 ㎜ 2 ~ 1.4 ㎜ 2 of the interlayer of the netted lattice form of moistureproof switch.The area of grid is unsuitable excessive, and excessive drier is fallen into switch inside easily; The grid area is difficult for little, influences drier and absorbs the interior moisture of switch.The present invention is in order to reach ideal effect, and each grid area of the interlayer of netted lattice form is designed to 1 ㎜ 2.
Further technological improvement of the present invention is that the drying box of moistureproof switch has seal cover outward, prevents that extraneous air from entering drying box, and sealing lid is transparent material, can see the suction state of drier.
The present invention obtains following technique effect:
By regular tap is carried out technological improvement, cost increases not obvious, can prevent effectively that the household electrical appliance switch from causing the potential safety hazard that electrical equipment damages and elimination produces because of electric leakage because of humidity.
Description of drawings
Fig. 1 is the side schematic view of a kind of moistureproof switch of the present invention.
Embodiment
Understand and enforcement the present invention for the ease of those of ordinary skills, the present invention is described in further detail below in conjunction with the drawings and the specific embodiments.
Embodiment
As shown in Figure 1, the invention discloses a kind of design of moistureproof switch.Comprise switch 1 body, seal protection cover 2 is arranged on the shift knob, protective sleeve 2 is the rubber material, and protective sleeve 2 can make switch 1 integral body be in sealing state, prevents that outside moisture content from entering.Switch 1 is equipped with drying box 3, in the drying box 3 drier is arranged.Drying box 3 inwalls have the interlayer 4 of netted lattice shape, can draw water in air part of switch 1 inside under the situation of switch 1 is not bled in the agent of keeping dry.Each grid area 1 ㎜ 2 of the interlayer 4 of the netted lattice form of switch 1.Seal cover 5 is arranged outside the drying box 3, seal cover 5 is transparent material, can see the suction state of drier, in addition for better reminding user to replace drier, the desiccant box external body has LED lamp 6, and drier adopts the lime drier, expands behind the adsorption moisture after making moist after the complete agent of drier is expanded, can trigger LED lamp 6 switches, in order to remind the user in time to change drier.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention does, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
