Description

The single-chip microcomputer timing heater

Technical field

The utility model relates to a kind of electric mosquito repellent heater, the especially heater of electrical heating anti-mosquito incense sheet mode.

Background technology

Summer, mosquito was many, needed to use anti-mosquito incense sheet and supporting heater, and anti-mosquito incense sheet is the special-purpose scraps of paper of a certain amount of mosquito liquid of pre-soaked mistake.Prior art is that anti-mosquito incense sheet is placed on the PTC thermistor, utilizes the PTC heat effect to make the anti-mosquito incense sheet sustained release, thus the kill mosquito mosquito repellent.Use initially, anti-mosquito incense sheet herb liquid content is higher, and volatile substance is more, passes in time, and the medicament contg volatilization reduces gradually.This just causes the volatilization of anti-mosquito incense sheet liquid not to be into steady state, but first high rear low, causing problem is one just to have brought into use interior space pharmaceutical gas content larger, will produce allergy, discomfort to sensitive group, baby, pregnant woman, the 2nd, use the later stage volatile substance to reduce, cause reaching repelling effect.

Summary of the invention

The purpose of this utility model is to provide a kind of multi-functional heater that possesses.

the purpose of this utility model is completed by following technical solution, the single-chip microcomputer timing heater, comprise mosquito-repellent incense disc type housing and built-in circuit, described built-in circuit comprises socket and the PTC heating plate that is connected, described socket is positioned at disc type housing one end face, described disc type housing upper surface is provided with the grid open-work corresponding with PTC heating plate position, it is characterized in that: described built-in circuit also comprises single chip machine controlling circuit, described single chip machine controlling circuit comprises connected power module of voltage regulation, single-chip microcomputer, relay, input key, described Single-chip Controlling port connects relay coil, described relay contact switch and PTC heating plate, the socket serial connection, also be connected with lighting circuit between described single-chip microcomputer and power module of voltage regulation.

Described lighting circuit comprises light source, the resistance of serial connection, is parallel with a key switch on described resistance.

Described light source is the LED lamp, and described LED lamp is located between housing socket and grid open-work, and described key switch is located at the housing another side relative with socket.

The utility model disconnects closed by single chip machine controlling circuit control relay contact, make the PTC heating plate stop or heating, keep stable state thereby reach the volatilization of anti-mosquito incense sheet liquid, avoid the anti-mosquito incense sheet liquid to concentrate on volatilization for the previous period, effectively continue the anti-mosquito incense sheet liquid volatilization time.Also comprise simultaneously a lighting circuit, resistance of series connection in circuit, the normal condition key switch disconnects, and in circuit, electric current is little, and display lamp brightness is less, is suitable for the instruction heater duty, and the eyes that do not stimulate the people.When needs threw light on to facilitate filling or change anti-mosquito incense sheet, key switch was closed, thereby makes resistive short, and in circuit, electric current becomes large, thereby display lamp brightness is strengthened, the operation that is convenient for people to.
