Abstract
The utility model discloses an automatic controller for the blast wind of the electric fan conducting various intermittent time control, mainly comprising a voltage stabilizing circuit for the electric source, a conversion circuit of intermittent time control and an executive driving circuit. In the tropical summer, many users have to open the electric fan for the whole night with electricity consumption and uncomfortable feeling. The automatic controller for the blast wind of the electric fan can enable the electric fan to generate sustained wind, even blast wind, long blast wind and short blast wind. The user can arbitrarily choose the working state of the automatic controller for the blast wind of the electric fan according to the environmental condition and the requirements with electricity consumption saving and comfortable and relaxed feeling. The utility model has the advantages of low cost, high reliability and strong practicability and can be arranged in the inner portion of the electric fan in match and can also be made into single product for sale.
Description
The utility model relates to a kind of electric fan fitful wind device, particularly a kind of simple and easy fitful wind device that can obtain multiple break time.
At present, the electric fan that uses in most of families does not all have the function of fitful wind.At the night of sweltering heat, not only power consumption is many for Yun Zhuan electric fan all night, and wind stimulates and produces various uncomfortable sensations when making the sleeper be subjected to growing.Existing electric fan fitful wind device is because cost height, function singleness, thereby generally do not applied.
The utility model has remedied the deficiency of the said goods, and it adopts fairly simple circuit, and electric fan is carried out multiple interruption running control automatically, can using electricity wisely, and the people is felt comfortably cool easily.
The purpose of this utility model is to provide the electric fan fitful wind automatic controller that a kind of cost is low, simple and practical, can carry out multiple control break time to the user.
The utility model is mainly by power supply stabilization circuit, break time control transformation circuit and carry out drive circuit and form.
Now in conjunction with the accompanying drawings:
In the accompanying drawing, power supply stabilization circuit is mainly by resistance R

2Filtering after, at DW
1Two ends obtain a galvanic current source, with its working power as relay J.By R
2And DW
2Constitute the secondary mu balanced circuit, make DW
2Two ends obtain a stable power more, with its working power as multi-vibrator.When multi-vibrator is worked, BG
2Rising that collector potential replaces and reduction (its cycle optionally can be designed at tens seconds to hundreds of between second), BG
3Also along with corresponding conducting with end, also corresponding adhesive of relay J and release, and by socket CZ to the power supply that electric fan output one is interrupted, reach the purpose of fitful wind.
This fitful wind device changes BG by throw over switch K
1And BG
2The base resistance resistance, make multi-vibrator according to carrying out work different break times.When K places gear 1, can make BG
3Saturation conduction, the J adhesive makes the electric fan continuous running.When K places gear 2, because BG
1Base resistance (R

2Conducting and deadline equate, also equate the adhesive of relay and release time, also equate the operation of electric fan and quiescent time.When K places gear 3, because R
6Made BG by short circuit
1Base resistance reduce BG
2Saturation time shorten, also shorten the release time of relay, promptly is longer than quiescent time (electric fan is in long fitful wind working state) running time of electric fan.When K places gear 4, because R
5Made BG by short circuit
2Base resistance reduce BG
2Deadline also shorten, also shorten the pickup time of relay, promptly is shorter than quiescent time (electric fan is in short fitful wind working state) running time of electric fan.
