Abstract
An electric heating fan with a movable light-shielding piece is composed of a fan head, a base and a controller. The fan head comprises a concave mirror and a front cover. The focal point position of the concave mirror is provided with a heating tube. A central plate of the front cover is circular. A rotary knob is installed on the central plate of the front cover. The rotary knob is fixedly connected with a circular plate after penetrating through the central plate. A kidney-shaped hole is formed in the circular plate. A rotating shaft of the light-shielding piece is installed inside the central plate of the front cover. A slide pin is installed at the inner end of the light-shielding piece and matched with the kidney-shaped hole. The side, facing towards the heating tube, of the light-shielding piece is a mirror surface. By rotating the rotary knob on the central plate of the front cover, the light-shielding piece can be conveniently unfolded or folded; the effective light-shielding radius can be increased by about 3 cm after the light-shielding is unfolded, and more than 70% of direct light can be shielded, and visible light of the heating tube can less stimulate the eyes of people.
Description
Technical field
The utility model relates to a kind of household electrical appliance, particularly a kind of electric heating fan with movable anti-dazzling screen.
Background technology
Electric heating fan is that electric heating is dispersed into the domestic heating electrical equipment in space, under season of the colds such as winter and environment, uses, and has become modern's indispensable household electrical appliance of living.Electric heating fan thermal source adopts advanced high-quality heater, heats up rapidly, and heat is concentrated and be luminous soft comfortable.Electric heating fan is again warmer, is the feature of drawing domestic and international advanced product, and well-designed forming has handsome in appearance, low power consumption, the thermal efficiency is high, thermoinduction is fast and heat is concentrated advantage.Easy to use, safe energy-conservation, be the desirable heating tools in place such as family, office.
But electric heating fan relies on heat-generating pipe and sends infrared ray and heat indoor, heat-generating pipe ultraredly also can send visible ray sending simultaneously, and common visible ray is yellow, orange and red, and heat-generating pipe temperature is higher, and the light sending is brighter.In darker environment, after turning off the light night, the visible ray that electric heating fan sends will affect people's sleep quality.
On market, have reflective electric heating fan, heat-generating pipe be arranged on outer cover one side, there is light shield in the place ahead of heat-generating pipe, the light that heat-generating pipe sends, by directive user after reflection shielding film, has been avoided light direct projection, can reduce the impact of visible ray on people.Because the size of light shield is fixed, in order to obtain good heating efficiency, the diameter of light shield is generally than the large 1-2cm of heat-generating pipe.At night, shaded effect is still not ideal enough.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of reflective electric heating fan that can change anti-dazzling screen diameter is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of electric heating fan, by fan head, base and controller, formed, fan head comprises concave mirror and front shroud, the focus place of concave mirror is provided with heat-generating pipe, the central plate of front shroud is circular, it is characterized in that: on the central plate of front shroud, knob is installed, knob is through after central plate, be fixedly connected with plectane, on plectane, there is mounting hole, the turning cylinder of anti-dazzling screen is arranged on the central plate inner side of front shroud, and the inner of anti-dazzling screen is provided with sliding pin, and sliding pin coordinates with mounting hole.
Described anti-dazzling screen is minute surface towards a side of heat-generating pipe.
Described anti-dazzling screen has 10, annular spread centered by plectane.
Compared with prior art, the utility model has the advantage of: rotate the knob on front shroud central plate, can open easily or draw in anti-dazzling screen, after anti-dazzling screen is opened, effectively shading radius can expand 3cm left and right, can shelter from more than 70% direct light, reduce the stimulation of heat-generating pipe visible ray to human eye.

Stereogram after Fig. 2, anti-dazzling screen are opened.
Structure chart when Fig. 3, single anti-dazzling screen are opened.
Structure chart after Fig. 4, single anti-dazzling screen draw in.
Structure chart when Fig. 5, whole anti-dazzling screen are opened.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
A kind of electric heating fan with movable anti-dazzling screen, by fan head, base and controller, formed, on base 5, there are driving switch 6 and time switch 7, fan head comprises concave mirror 2 and front shroud 3, the focus place of concave mirror is provided with heat-generating pipe 1, the central plate 12 of front shroud is circular, 3 one-tenth radial distributions of front shroud.Prevent that other article from touching heat-generating pipe, causes fire.
The radius of central plate 12 is generally 6cm left and right.Central plate centres a knob 11 is installed, knob, through after central plate, is fixedly connected with plectane 13.Uniform 10 mounting holes 17 on plectane.
As shown in Figure 3 and Figure 4, anti-dazzling screen has 10 to the shape of anti-dazzling screen 14, annular spread centered by plectane.On anti-dazzling screen, there is shaft hole,, turning cylinder 15 is fixed on the inner side of central plate.The A end of anti-dazzling screen has sliding pin 16, and the mounting hole 17 on sliding pin 16 and plectane coordinates.Anti-dazzling screen tilts to install, and A end is near central plate, and B end decentre plate is far away.
Anti-dazzling screen 14 is minute surface towards a side of heat-generating pipe, and infrared ray and visible ray are reflected back to concave mirror 2, reduces heat loss.
As shown in Figure 5, when clockwise rotating knob 11, knob 11 drives plectane 13 to rotate, and then anti-dazzling screen is rotated around the turning cylinder 15 of oneself, and B end stretches out from central plate below, and is spliced into a complete annulus.Can shield better visible ray, reduce light and pollute, be beneficial to sleep.
As shown in Figure 6, when rotating counterclockwise knob 11, the B of anti-dazzling screen end is hidden in the below of central plate, has reduced the area of shading, and heating efficiency is higher.
