Abstract
The utility model relates to an electric hair dryer with a stepless synchronous regulation function, and mainly solves the problem that the air outlet temperature and the air speed of the conventional electric hair dryer cannot be regulated synchronously. The electric hair dryer with the stepless synchronous regulation function is characterized in that an electromotor (2) and an electric heating element (3) are connected in parallel and then connected with a bidirectional triode thyristor (4) in series, a control electrode of the bidirectional triode thyristor (4) is sequentially connected in series with the cathode of a diode (5), a first resistor (6) and a potentiometer (7) provided with a switch, two ends of the potentiometer (7) are connected with a first capacitor (11) in parallel, and a knob (8) placed outside a casing (1) is connected onto the potentiometer (7). According to the electric hair dryer with the stepless synchronous regulation function, the knob is adopted to steplessly regulate the resistance value of the potentiometer to regulate a conduction angle of the bidirectional triode thyristor, so that stepless regulation of the output power of the electric heating element and the rotational speed of the electromotor is achieved, and the electric hair dryer has the characteristics of simple structure, convenience in regulation and low cost.
Description
Technical field
The utility model relates to a kind of hair drier, is specifically related to a kind of stepless synchronous regulation and control hair drier.
Background technology
Hair drier is a kind of hair waving appliance of commonly using, mainly by housing, motor, fan blade and heating, formed, heating adopts heating wire conventionally, fan leaf is installed on motor, motor drives fan leaf rotation, air is sucked from air inlet, through heating heating, from air duct, blow out hot blast.Hair drier in the market has two grades or third gear to regulate power and the wind speed of heating wire, and then temperature and the wind speed of change blowing, can not stepless continuous regulate the blowing temperature and the wind speed that reach applicable, leaving air temp and wind speed can not adjusted in concert and are matched.Chinese patent CN201220501289.1 discloses a kind of hair dryer, although can carry out step-less adjustment blowing temperature and wind speed, but it still can not make leaving air temp and wind speed adjusted in concert and match, and adopt the electronic components such as single-chip microcomputer, circuit structure is complicated, cost is higher, is not suitable for universal and promotes.
Utility model content
In order to overcome the deficiency that existing hair drier leaving air temp and wind speed can not adjusted in concert, the utility model provides a kind of stepless synchronous regulation and control hair drier, this stepless synchronous regulation and control hair drier adopts the resistance value of knob step-less adjustment potentiometer to carry out the controlled double-direction silicon controlled angle of flow, realize the power output of heating and the step-less adjustment of motor speed, there is feature simple in structure, easy to adjust and that cost is low.
The technical solution of the utility model is: a kind of stepless synchronous regulation and control hair drier, comprise the motor and the heating that are arranged in housing, motor is connected in series with bidirectional triode thyristor mutually with after heating parallel connection, the control utmost point of bidirectional triode thyristor is the potentiometer of series diode negative pole, the first resistance and belt switch successively, the two ends of described potentiometer are parallel with the first electric capacity, are connected with the knob being placed in outside housing on potentiometer.
On the branch road of described heating, be in series with normally closed type press button, housing is provided with the button of actuation button switch outward.
The two ends of described diode are parallel with the second electric capacity.
The utlity model has following beneficial effect: the utility model in use, rotation knob, switch opens on potentiometer, bidirectional triode thyristor conducting, motor and heating are started working, turning knob changes the resistance value of potentiometer, and then the angle of flow stepless variation between 0-180 ° of change bidirectional triode thyristor, the electric current that flows through bidirectional triode thyristor is along with the resistance of potentiometer reduces and increases, the faster rotational speed of motor in the time of heating increased power (blowing temperature raises), the power output of heating and the step-less adjustment of motor speed have been realized, circuit structure is simple, easy to adjust, cost is low, be beneficial to popularization.
