Abstract
The utility model relates to a hand-injured-resistant type infrared sensing electric fan which comprises a fan body and infrared sensing switches. The hand-injured-resistant type infrared sensing electric fan is characterized in that a motor is arranged at the upper end of the fan body. Fan blades are arranged on a main shaft of the motor, a net sleeve is arranged on the peripheries of the fan blades, a power gear switch is arranged at the lower end of the fan body, the infrared sensing switches are arranged on the centers of the front surface and the back surface of the net sleeve, and the infrared sensing switches are connected between the power gear switch and the motor in series through leading wires. According to the hand-injured-resistant type infrared sensing electric fan, whether an object exists near the net sleeve can be monitored through the infrared sensing switches, if the object exists, the infrared sensing switches are turned off automatically, so that the motor loses power and stops running, and accordingly the hidden problem that a child puts fingers into the fan so that the fingers can be injured is solved.
Description
Technical field
Novel a kind of fan, the especially a kind of anti-hand formula infrared ray electric fan of hindering of relating to of this use.
Background technique
Fan is a kind of household electric appliance that utilize the motoring flabellum to rotate to reach to make air to accelerate circulation, and it is mainly used in cooling and heatstroke-eliminating and ventilating air.Be widely used in family, office, shop, hospital and hotels and other places.
Fan kind on the market is various at present, and their structure is roughly the same, generally is that its upper end is provided with the fan driven by motor head, the lower end is provided with base, in order to allow the efficient of blowing reach maximum, and can not allow flabellum scratch the people again, so the periphery of fan head all is provided with wire hood.Guard is the flabellum packing, can prevent that flabellum from hurting sb.'s feelings, but the slit on the guard can allow still finger to put in, and there is very large potential safety hazard in this for thoughtless child.
The model utility content
Guard at said fans can allow child's finger to put in, the problem that has potential safety hazard, the purpose of this utility model provides a kind ofly anti-hinders hand formula infrared sensing electric fan, and its guard is provided with the infrared ray sensing switch, can prevent that child's finger is hindered by the flabellum strand.
In order to realize that the technological scheme that the purpose of this utility model adopts is: a kind ofly anti-hinder hand formula infrared sensing electric fan, it comprises fan body, infrared ray sensing switch; It is characterized in that: the upper end of described fan body is provided with motor, and the main shaft of motor is provided with flabellum, and the periphery of flabellum is provided with guard; The lower end of described fan body is provided with the power supply driving switch; Described infrared ray sensing switch is located at former and later two lip-deep centers of guard, and it is connected between power supply driving switch and the motor by lead.
The beneficial effects of the utility model are: whether its infrared ray sensing switch can be monitored guard has object on every side, if object is arranged, the automatic disconnection of infrared ray sensing switch causes the motor dead electricity, and shut down, thereby prevent that child from pointing the potential problem of putting into fan quilt strand wound.
Description of drawings
Fig. 1 is topology view of the present utility model.
Fig. 2 is electrical schematic diagram of the present utility model.
Among the figure, 1-guard, 2-infrared ray sensing switch, 3-power plug, 4-power supply driving switch.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
In Fig. 1, first embodiment shown in Figure 2, a kind ofly anti-ly hinder hand formula infrared sensing electric fan, it comprises fan body, infrared ray sensing switch; It is characterized in that: the upper end of described fan body is provided with motor, and the main shaft of motor is provided with flabellum, and the periphery of flabellum is provided with guard; The lower end of described fan body is provided with the power supply driving switch; Described infrared ray sensing switch is located at former and later two lip-deep centers of guard, and it is connected between power supply driving switch and the motor by lead.
In Fig. 1, second embodiment shown in Figure 2, the rear end of described fan body is provided with power plug; Described infrared sensor switch sends actinoid IR, and when IR was reflected by the object back, infrared sensor switch will disconnect.
Power plug is inserted on the external circuit socket, the opening power driving switch, motor can drive the flabellum rotation, when having object to occur near the guard, the infrared ray sensing switch will detect object, and automatic disconnection, causes the motor dead electricity, motor shuts down, thereby avoids in child's finger plug air intake fan guard by the phenomenon of strand wound.
