Abstract
The utility model relates to an electric mosquito killer which comprises a mosquito killer disc-type shell and a built-in circuit, wherein the built-in circuit comprises a socket; the socket is positioned on one end face of the disc-type shell; the built-in circuit is further connected with a change-over switch; the change-over switch comprises two moving contacts; one moving contact is directly connected with a timing PTC (Positive Temperature Coefficient) heating plate module, and the other moving contact is connected with a circulating on-off control circuit and then connected with the timing PTC heating plate module; the circulating on-off control circuit is used for controlling a PTC heating plate to perform intermittent heating. The change-over switch enables the electric mosquito killer to have two mosquito-repellent incense liquor release rates, so that the requirements of mosquito killing and mosquito repellent in different indoor spaces can be met.
Description
Technical field
The utility model relates to a kind of electric mosquito repellent, especially the electric fumigator for preventing mosquito 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 timing electric mosquito-repellent incense device 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, a kind of electric fumigator for preventing mosquito, comprise mosquito-repellent incense disc type housing and built-in circuit, described built-in circuit comprises socket, and described socket is positioned at disc type housing one end face, it is characterized in that: described built-in circuit also connects a change-over switch, this change-over switch has two movable contacts, a movable contact directly connects regularly PTC heating plate module, and another movable contact connects the circulation on-off control circuit, then connects regularly PTC heating plate module; Described circulation on-off control circuit is controlled PTC heating plate intermittent-heating.
Described circulation on-off control circuit comprises two auxiliary reclays, two time relays (KT1, KT2), described two time relays (KT1, KT2) are connected in parallel on an auxiliary reclay (KM1) coil, another auxiliary reclay (KM2) coils from parallel connection of coils is on the time relay (KT1) coil, and described auxiliary reclay (KM2) switch is connected to socket and reaches in the PTC heating plate electric mosquito repellent circuit that is connected.
Described timing PTC heating plate module comprises PTC heating plate and the timing control circuit that is connected, described timing control circuit comprises connected 555 timers (U1), the second resistance (R2), adjustable resistance (RP), electric capacity (C4, C5), diode (D3), triode (Q1), button (S1) and relay (J), and relay (J) switch connects the PTC heating plate.
Described disc type housing upper surface is provided with the grid open-work corresponding with PTC heating plate position.
The utility model arranges a change-over switch in the electric fumigator for preventing mosquito built-in circuit, switch can switch on normal laser heating circuit and circulation on-off control circuit.When the needs laser heating just is arranged on change-over switch direct connection PTC heating plate, when the interior space is suitable for slowly, evenly discharging the anti-mosquito incense sheet liquid, just change-over switch can be arranged on communication loop on-off control circuit gear, this circulation on-off control circuit utilizes the delay function of the time relay, realizes continuous circulation and the on off operating mode delay function of connecting and disconnecting of the circuit state.This just makes heating plate realize a period of time heating and a period of time stopped heating, make the volatilization of anti-mosquito incense sheet liquid keep stable state, 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 occurs, and, effectively continue the anti-mosquito incense sheet liquid volatilization time.The timing PTC heating plate module that is provided with simultaneously can guarantee to use the rear automatic shutdown circuitry of end, saves energy.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed introduction:
As shown in Figure 1, 2, 3: a kind of electric fumigator for preventing mosquito, comprise mosquito-repellent incense disc type housing and built-in circuit, built-in circuit comprises socket 2, the change-over switch 3 that connects power supply 1, this switch one end has two movable contacts, a movable contact directly connects regularly PTC heating plate module 5, regularly PTC heating plate module comprises PTC heating plate and the timing control circuit that is connected, and another movable contact connects circulation on-off control circuit 4, then connects regularly PTC heating plate module; This circulation on-off control circuit is controlled the interim regularly break-make of built-in circuit, thereby realizes PTC heating plate intermittent-heating.The socket that connects civil power exposes disc type housing one end face, and disc type housing upper surface is provided with the grid open-work corresponding with PTC heating plate position, and change-over switch is arranged between grid open-work and socket.
Regularly PTC heating plate module comprises PTC heating plate and the timing control circuit that is connected, described timing control circuit comprises connected 555 timers (U1), the second resistance (R2), adjustable resistance (RP), electric capacity (C4, C5), diode (D3), triode (Q1), button (S1) and relay (J), and relay (J) switch connects the PTC heating plate.
The circulation on-off control circuit comprises two auxiliary reclays (KM1, KM2), two time relays (KT1, KT2), described two time relays (KT1, KT2) are connected in parallel on an auxiliary reclay (KM1) coil, another auxiliary reclay (KM2) coils from parallel connection of coils is on the time relay (KT1) coil, and described auxiliary reclay (KM2) switch is connected to socket and reaches in the PTC heating plate built-in circuit that is connected.The present embodiment KT1 time-delay 10 minutes, KT2 time-delay 3 minutes, this just makes PTC heating plate heating 10 minutes, then stops in 3 minutes, makes the volatilization of anti-mosquito incense sheet liquid keep stable state.
