Abstract

The utility model relates to a timing heating mosquito-repellent incense circuit. The timing heating mosquito-repellent incense circuit comprises a socket, a PTC heating sheet connected with the socket, and a single chip microcomputer control circuit. The single chip microcomputer control circuit comprises a single chip microcomputer, a power supply, a display circuit, a heating stop control circuit, and a relay, wherein the power supply, the display circuit, the heating stop control circuit, and the relay are connected with the single chip microcomputer. The contact of the relay is connected with the PTC heating sheet and the socket in series and presets a time switch according to the heating stop control circuit. The timing heating mosquito-repellent incense circuit maintains a steady volatilization state of the liquid of the mosquito-repellent incense.

Description

Timing heated mosquito-repellent incense circuit

Technical field

The utility model relates to a kind of circuit, especially the circuit of electric mosquito repellent.

Background technology

Summer, mosquito was many, needed to use anti-mosquito incense sheet and supporting well 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 timing heated mosquito-repellent incense circuit that guarantees the constant volatilization of anti-mosquito incense sheet herb liquid content energy.

The purpose of this utility model is completed by following technical solution, timing heated mosquito-repellent incense circuit, comprise socket and the PTC heating plate that is connected, it is characterized in that: also comprise single chip machine controlling circuit, described single chip machine controlling circuit comprises single-chip microcomputer, and the power supply that is connected with single-chip microcomputer, display circuit, heating stopping control circuit, relay; The contact of described relay and PTC heating plate, socket series connection, described relay contact sets in advance clock switch according to the heating stopping control circuit.

Described heating stopping control circuit comprises the reset key (S1) that connects the monolithic processor resetting pin, button one (S2) end connects the T0 pin, the other end connects series winding external vibrator circuit, and button two (S3) end connects the T1 pin, and the other end connects series winding external vibrator circuit.

The utility model circuit is by single-chip microcomputer and external heating stopping control circuit, this control circuit arranges relay contact by button S2 and disconnects duration, button S3 arranges the relay contact closure duration, thereby control the PTC heating plate working time, reach and make heating plate realize a period of time heating, a period of time stopped heating, make the volatilization of anti-mosquito incense sheet liquid keep steady state (SS), not only avoid the anti-mosquito incense sheet liquid to concentrate on volatilization for the previous period, so that the uncomfortable state of human body appears, and, effectively continue the anti-mosquito incense sheet liquid volatilization time, guarantee result of use.
