The utility model uses a low-voltage DC power supply to work, greatly improves the safety of the electric appliance, can make the fan surface approach to the human body to the nearest degree for generating soft breeze, and reaches the mosquito and insect repelling effect without disturbing the sleeping of people.
Description
Technical field
The utility model relates to a kind of electronic fan, relates in particular to the electronic fan of a kind of bedroom special use.
Background technique
Electronic fan is a kind of common household electric appliance, is commonly called as electric fan, and Modern Family is herbal almost.Electric fan is various in style, but nearly all is based on the wind wheel type principle, and the wind of generation is nature not, allows the people feel under the weather.In addition, people usually use mosquito net in order to hide biting of mosquito, and mosquito net makes the people stuffy, and using electric fan to blow can repel mosquitoes, but wind little dispersion effect undesirable, wind is big to make the people not only uncomfortable but also easy to catch cold.Traditional fan, energy-conserving and environment-protective, graceful comfortable, but total very important person goes operation too tired.
The model utility content
The purpose of this utility model provides a kind of electric household fan that is specifically applied to the bedroom repel mosquitoes, and this electronic fan moulding uniqueness, mosquito repellent are given birth to wind, and its effect can substitute electric fan and the mosquito net in the bedroom fully.
For this purpose, the utility model adopts following scheme:
The electric household fan includes pedestal, drive unit, fan handle and covering of the fan.Described pedestal is vertically placed, can the telescopic adjustment height, and the inner drive unit of installing supports fan handle by drive unit; Described drive unit is installed in the pedestal, the gear drive that includes circuit for controlling motor, DC speed-reducing and be attached thereto; Described fan handle is laterally placed, and hangs with covering of the fan, is mounted on the drive unit by the retaining hole.Circuit for controlling motor is powered to DC speed-reducing, reducing motor drives fan handle by gear drive and does fan-shaped rotation, after turning over several angle, circuit for controlling motor oppositely powers for DC speed-reducing, and the reducing motor backward rotation drives fan handle by gear drive and back and forth agitates.
The beneficial effects of the utility model are:
Embodiment of the present utility model is by adopting the power plant of DC speed-reducing as fan, can use low-voltage dc power supply work, the Security of this kind electrical equipment and the flexibility of power supply have been improved greatly, simultaneously, because direct current generator is easy to control, make fan movement speed, strength of action, agitate angle, operation program etc. to be easy to realize, make functional diversities.By the fan handle that grows, can make covering of the fan nearest near human body, produce very soft gentle breeze, promptly driven mosquito, left people's sleep in peace again.
Below in conjunction with accompanying drawing the utility model is described in further detail.
