The utility model provides an electronic mosquito dispeller. The electronic mosquito dispeller comprises an outer casing, an electric heating element and mosquito repellent agent, and is characterized in that the electronic mosquito dispeller is also provided with a heating controlling circuit composed of a power supply circuit, an MCU chip and a relay; the input terminal of the power supply circuit is connected with an external alternating current power supply, the output terminal is connected with the power supply terminal of the MCU chip, the relay is connected with the electric heating element in series, and the control terminal is connected with the MCU. The electronic mosquito dispeller controls the on-off of the relay through the MCU chip to achieve the purpose of controlling the work of the electric heating element, thereby the electronic mosquito dispeller can be aromatically closed at fixed time, and can adjust the volatilize quantity of the agent according to the size of the operating environment.
Description
Technical field
The utility model relates to a kind of mosquito-driving device, particularly a kind of electronic mosquito repellent that utilizes the work of MCU chip controls heater element.
Background technology
Mosquito expelling equipment has been widely used in daily life as the effective tool of mosquito repellent.Existing mosquito expelling equipment is simple in structure, all is to adopt electrical heating element heating anophelifuge to make its volatilization, reaches the purpose of mosquito repellent.But this mosquito expelling equipment cannot shut down automatically, if the user forgets the power supply of closing mosquito expelling equipment, will produce the phenomenon of waste electric energy and anophelifuge, further can produce disaster hidden-trouble.
In addition, existing mosquito expelling equipment can't be regulated the volatile quantity of medicament according to the size of environment for use, so just, can't effectively utilize anophelifuge, be what is more, use mosquito expelling equipment in the space that area is less, owing to can't regulate the volatile quantity of medicament, make the user suck more anophelifuge, can influence the healthy of user like this.
Summary of the invention
The purpose of this utility model provides a kind of electronic mosquito repellent that can effectively overcome the problems referred to above, this electronic mosquito repellent has MCU chip and relay, reach the purpose of control electrical heating element work by the break-make of MCU chip controls relay, make electronic mosquito repellent timing automaticly to shut down, and can regulate the volatile quantity of medicament according to the size of environment for use.
The purpose of the utility model structure is achieved in that it comprises shell, electrical heating element, anophelifuge, and its improvement is that it also is provided with the heating control circuit of being made up of power circuit, MCU chip and relay; The input of power circuit links to each other with extraneous AC power, and its output links to each other with the power end of MCU chip, and relay is connected in series with electrical heating element, and its control end links to each other with MCU;
In the said structure, the MCU chip also links to each other with light-emitting component with gauge tap;
In the said structure, relay is an electromagnetic relay, and its movable contact and stationary contact are on the loop at electrical heating element place, and its coil is connected with the MCU chip;
In the said structure, the MCU chip adopts the SN8PXXXXB family chip.
In sum, the utility model electronic mosquito repellent is provided with the heating control circuit, wherein the MCU chip transmits control signal to relay according to the program of setting, reach the purpose of control electrical heating element work by the break-make of control relay, make electronic mosquito repellent in the time of setting, shut down automatically, and, control the volatile quantity of medicament by the operating frequency of control electronic mosquito repellent according to the size of environment for use.
Description of drawings
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is the schematic block circuit diagram of the utility model electronic mosquito repellent
Fig. 2 is the circuit theory diagrams of the utility model electronic mosquito repellent
Embodiment
As shown in Figure 1, 2, the circuit of the utility model electronic mosquito repellent comprises power circuit 1, MCU chip 2, relay 3, electrical heating element 4, gauge tap (comprising touch-switch 5 and vibroswitch 6) and light-emitting component 7 compositions.The input of power circuit 1 links to each other with extraneous 220V AC power, and its output links to each other with the power end VCC of MCU chip 2, and power circuit converts the 220V alternating current to the 5.6V direct current by transformer and uses for MCU chip and light-emitting component.The MCU chip adopts the SN8P2501B chip, its LOB2 end is connected with the coil of relay, the movable contact of relay and stationary contact are on the loop at electrical heating element place, this loop connects extraneous 220V AC power, the LOA0 end of MCU chip is connected touch-switch and vibroswitch respectively with the DATA end, the MCU chip also links to each other with light-emitting component, and light-emitting component is the LED illuminator.
During electronic mosquito repellent work, can select the different mode of operation of electronic mosquito repellent by touch-switch 5.For example, select timing mode by touch-switch, after the LOA0 end of MCU chip was received corresponding signal, the MCU chip called corresponding program and carries out, after timing arrives, the LOB2 end output current of MCU chip, electric current flows through the coil of relay, produces electromagnetic induction, thereby the movable contact of relay is separated with stationary contact, so just, disconnected the loop at electrical heating element place, electrical heating element is no longer worked, and electronic mosquito repellent has also stopped work.In addition, according to the size of environment for use, can also regulate the volatile quantity of medicament by touch-switch, when environment for use hour, send a signal to the LOA0 end of MCU chip by touch-switch, the MCU chip calls corresponding program and carries out control work, and at this moment, the signal that sends that the LOB2 end can be interrupted is given relay, control its break-make, thereby make electrical heating element also work discontinuously, the volatile quantity of anophelifuge also can reduce like this, and neither wasting medicament can not influence the healthy of user yet.Just can control the volatile quantity of anophelifuge by the frequency of regulating relay break-make.
In addition, the LED illuminator on the electronic mosquito repellent comprises that seven painted eggsells dodge LED lamp, relay indicating light and orange LED lamp, touches vibroswitch, and the MCU chip can send control signal and give the LED illuminator, realizes that its switch switches.
