Abstract
The utility model discloses a fan wind speed regulating device which comprises a voltage regulator, wherein the voltage regulator is provided with a starter which is connected with the voltage regulator in parallel. The fan wind speed regulating device mainly uses the fact that the starter can periodically switch on and cut off a power supply. When the starter is switched on, all power supply voltages are applied to a motor of a fan. When the starter is cut off, part of the power supply voltages are applied to the motor of the fan, and part of the power supply voltages are applied to the voltage regulator. Therefore the motor of the fan is powered with periodical high-low changing voltages, a wind supply mode of natural wind is imitated, noise is reduced, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of household electric appliance, particularly a kind of fan wind-speed adjusting device.
Background technique
Existing electric fan blast device, great majority all be can only the modulation electric fan motor power supply voltage, make motor be in confession, breakpoint two states.When power supply, motor runs up; During outage, motor relies on the inertia decelerate, thus imitating natural wind.The electric fan motor be in frequently all the time supply, the breakpoint state, noise increases, the life-span is short.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of power supply voltage that can automatic Modulation electric fan motor and produces periodically high and low fan wind-speed adjusting device.
The technical problems to be solved in the utility model is to realize by the following technical programs.The utility model is a kind of fan wind-speed adjusting device, comprises pressure governor, is characterized in: be provided with a Fluorescent Lamp Starter in parallel with it on the pressure governor.
Compared with prior art, the utility model is when voltage is high, and motor runs up; When voltage was low, motor was extenuated to low-speed running by running up, thus natural wind simulating, under the effect of Fluorescent Lamp Starter, electric fan has power supply voltage all the time, and motor rotary speed changes level and smooth, and air quantity changes nature.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, further describe concrete technological scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not consist of the restriction of its power.
Embodiment 1, and with reference to Fig. 1, a kind of fan wind-speed adjusting device comprises pressure governor, is provided with a Fluorescent Lamp Starter in parallel with it on the pressure governor.
The utility model is comprised of a Fluorescent Lamp Starter that is connected in parallel on the pressure governor, mainly is the performance of utilizing periodically conducting of Fluorescent Lamp Starter, cutting off the electricity supply.When the Fluorescent Lamp Starter conducting, supply voltage all is added on the electric fan motor, and when Fluorescent Lamp Starter cut off, a supply voltage part was added on the electric fan motor, and a part is then fallen on pressure governor, thereby the electric fan motor is on the power voltage supply that periodically height changes.Switch is selector switch.
