Abstract

The utility model relates to a control device for electric mosquito-repellent incense, which comprises a control unit, a throttle, a single key switch, an LED indicator lamp group, a neon lamp, etc. The control unit is an IC timer, and the interior is burned with a procedure used for a manufacturer to set various kinds of time selection according to needs; the electric mosquito-repellent incense can also be automatically driven to act again after a plurality of hours (twenty-four hours). In addition, the control unit can be connected with a power failure indicator, and the user can be prompted that the electric mosquito-repellent incense is in the power failure state through a flickering light source of the power failure indicator and needs resetting.

Description

The electric mosquito repellent control device

The utility model relates to a kind of electric mosquito repellent control device, particularly a kind of when electric mosquito repellent is used behind setting-up time, through some hrs, still can order about the device that electric mosquito repellent moves once again automatically.

Existing electric mosquito repellent does not possess the function of setting-up time usually, and it only has a time switch, a power supply indicator and cooperates inner circuit component units, drives the electric mosquito repellent action; Or the electric mosquito repellent of a type is arranged, and have the function of setting-up time, select in order to the user.But in a single day setting-up time surpasses in design, must push the switch of setting-up time again again, does not have the function of using continuously automatically, promptly through some hrs (24 hours) afterwards, can order about electric mosquito repellent and move once again.

Main purpose of the present utility model provides a kind of electric mosquito repellent control device, and it is that promptly the shortcoming that must select is once again again improved, and makes it easy to use, has practicality after being used in setting-up time at electric mosquito repellent.

For achieving the above object, the utility model provides a kind of electric mosquito repellent control device, it comprises: component units such as control module, thyristor, singly-bound switch and LED light group, wherein control module is an IC timer, burning has program in it, can set multiple selection of time by demand for manufacturer; The LED light group is connected in control module, and it can be according to the asynchronism(-nization) of setting, luminous demonstration; The gate of thyristor is connected in control module, and an end is connected in power supply, and the other end connects the heater of electric mosquito repellent; The singly-bound switch is connected in control module, with the setting-up time of selecting electric mosquito repellent to use.Its circuit design of mat after electric mosquito repellent is used in setting-up time, through some hrs, still can be ordered about electric mosquito repellent automatically and move once again.

Now the embodiment shown in conjunction with the accompanying drawings describes structure of the present utility model and function in detail.Wherein:

Fig. 1 is the calcspar of the utility model circuit;

Fig. 2 is a circuit diagram of the present utility model;

Fig. 3 is the flow chart of the utility model control.

The explanation of figure number and circuit unit title thereof:

1 control module (timer), 2 thyristors, 3 singly-bound switches, 4 power failure display lamps

5 LED lights, 6 neon lamps, 7 heaters

As illustrated in fig. 1 and 2, electric mosquito repellent of the present utility model control comprises: control module 1, thyristor 2, singly-bound switch 3, power failure indicator 4, LED light group 5, a neon lamp 6 and a unit such as heater 7.

Control module 1 is an IC timer, and burning has program in it, can set multiple selection of time by demand for manufacturer.In embodiment of the present utility model, be provided with 2 hours, 4 hours, 8 hours, 10 hours, 12 hours and continuous hour.

LED light group 5 is connected in control module 1, and these LED light groups can be according to the asynchronism(-nization) of setting, luminous demonstration.

The gate of thyristor 2 is connected in control module 1, and the M1 end is connected in power vd D, and the M2 end connects the heater (Load) 7 of electric mosquito repellent, and this thyristor 2 connections one neon lamp 6, learns in order to the user whether electric mosquito repellent moves.

Power failure indicator 4 is connected in control module 1, in embodiment of the present utility model, surpasses 40 seconds if having a power failure, and this power failure indicator 4 promptly can be shinny, and can remind the user to reset the time.

Singly-bound switch 3 is connected in control module 1, with the setting-up time of selecting electric mosquito repellent to use.

After the user pushed singly-bound switch 3 and selects setting-up times, control module 1 promptly can drive thyristor 2 conductings, makes heater 7 actions, and carries out according to control module 1 internal processes, to detect electric mosquito repellent service time.

Be illustrated in figure 3 as flow chart of the present utility model.At first, the user presses the singly-bound switch, selects setting-up time LED light group in step 31; In step 32, wherein a LED light can be shinny; And, drive the thyristor conducting in step 33, make the electric mosquito repellent action; Then, in step 34, control module detects electric mosquito repellent and whether surpasses setting-up time actuation time.

If do not surpass, program is got back to step 32, and LED light continues shinny; If the time surpasses, then program enters step 35, and action stops, and whether detects dwell time above 24 hours in step 36.

If do not surpass 24 hours, flow process is got back to step 35, and action still stops; If surpass 24 hours, then flow process is got back to step 32 automatically, and can push the singly-bound switch shown in step 31, resets.

In above-mentioned action, if power off time surpasses 40 seconds, then this power failure indicator 4 can glimmer, and resets to remind the user.

In sum, electric mosquito repellent control device of the present utility model is after being used in setting-up time at electric mosquito repellent, promptly the shortcoming that must reselect is improved, after making electric mosquito repellent be used in setting-up time,, still can order about the device that electric mosquito repellent moves once again automatically through some hrs.
