Abstract
The utility model provides a high-effect energy-saving electric heating mosquito killer adopting a PTC heating element. The high-effect energy-saving electric heating mosquito killer is characterized in that a timing circuit composed of a 555 time-base integrated package and a charging and discharging return circuit of the signal input terminal of the integrated package is arranged. The signal output terminal of the time-base integrated package is connected with the control terminal of a thyristor BCR connected in series with a PTC power supply return circuit. In the high-effect energy-saving electric heating mosquito killer, the method of the continuous operation of the heating element of electric heating mosquito killers in the prior art is changed into the method of intermittent operation. Compared with the prior art, the electric mosquito killing tablets are saved by 2/3, and electricity is saved by 60%.
Description
The utility model relates to mosquito killing device.More particularly, be a kind of be the efficient energy-saving electrothermal mosquito-killing unit of heating element heater with PTC.
Electric mosquito killing device is owing to sanitation and hygiene, the welcome that is subjected to people easy to use.But, electric mosquito killing device of the prior art all is to adopt the working method of heating continuously, this has just caused, and in use leading portion effect in period is stronger, and the indoor denseer mosquito-repellent incense of assembling is distinguished the flavor of even some babies and old man are not felt well, and the later stage effect obviously weakens.
The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of efficient energy-saving electrothermal mosquito-killing unit is provided.By timing means is set, heating element heater is worked in the mode of being interrupted, make the indoor medicine fragrance comparatively uniformly that in the long time, keeps.
The purpose of this utility model is realized by following technical scheme.
The utility model adopts the PTC heating element heater.
Feature of the present utility model is to be provided with by 555 o'clock base integrated packages and to discharge and recharge element R
2, R
3, D
4, C
3The timing circuit that constitutes, the signal output part (the 3rd pin) of described 555 o'clock base integrated packages is connected with the controllable silicon BCR control end in being connected on the PTC electric power loop.Feature of the present utility model also is the described element R that discharges and recharges
3, D
4Be connected between 555 o'clock base integrated package the 2nd, the 7th pin resistance R in parallel
2Be connected across the 7th pin and dc source anode; Capacitor C
3Be connected across the 2nd pin and dc source negative terminal.
Become the capacity cell C of block signal input along with being connected 555 o'clock basis sets
3Repeating of charge and discharge process, corresponding with it, become the block signal output to present replacing of high and low level at 555 o'clock basis sets, and then make the electric power loop of heating element heater PTC replace break-make by controllable silicon BCR, the PTC heating element heater is interrupted work with certain cycle.
Experiment shows that after 20 minutes, mosquito is promptly shot or lose dead the ability of biting to mosquito-killing unit in continuous operation, and quit work this moment, and indoor remaining drug effect of distributing still can keep more than one hour.This shows that the working method that the utility model adopts heating element heater to be interrupted can be brought into play drug effect better.Compared with the prior art, the utility model can be saved mosquito killing tablets 2/3, economize on electricity 60%.
Accompanying drawing is the utility model circuit theory diagrams.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing, 220
V ～Line voltage is through C
1Step-down, D
1Voltage stabilizing, D
2Rectification, D
3The secondary voltage stabilizing, and through C
2Filtering provides 8.2 volts of direct-current working volts Vcc to 555 o'clock base integrated packages, start initial stage capacitor C
3Both end voltage is zero, because the electric capacity both end voltage can not be suddenlyd change, at this moment, 555 the 2nd pin are low level, its output the 3rd pin output high level, and controllable silicon BCR conducting, the PTC electric power loop is connected, and devotes oneself to work.Meanwhile, the 82V DC voltage is through R
2, D
4To C
3C is worked as in charging
3Terminal voltage when rising to 2/3 Vcc, the upset of 555 outputs the 3rd pin is low level, the PTC electric power loop disconnects, and stops heating.At this moment, C
3Pass through R again
3Discharge over the ground with 555 the 7th pin, work as C
3Terminal voltage when dropping to 1/3 Vcc, 555 the 3rd pin are again then output high level, circulation according to this.In the present embodiment, C
3Terminal voltage be increased to 2/3 Vcc from zero and need 11R
2C
3Second, need 055R approximately and drop to 1/3 Vcc from 2/3 Vcc
3C
3Second, change R
2, R
3And C
3Value, can obtain the different work periods.Capacitor C among the figure
1Select the electric capacity of the dacron of withstand voltage 400V for use, D
