Abstract

The fan has a conical guide 6 in an upper protection cover 3 of a fan 2 for guiding air flow to disperse in 360 degree, a lamp hood 5 on the guide 6, an appropriate lighting element (62 Fig. 4) and a set of batteries 63 in the guide 6, and a push-button switch 51 in the center of the upper protection cover 3 to turn on and off the lighting element (62). The lamp hood 5 is formed with a plurality of slots (53 Fig. 4) so that a plurality of openings 67 are formed after assembly of the guide 6 and the lamp hood 5, and an appropriate quantity of cotton or other water-absorptive material is placed in the guide 6 so that perfume can be poured through the openings and then absorbed by the cotton or other water-absorptive material to provide aromatic smell during operation of the fan. <IMAGE>

Description

"A Structure of Fan" The present invention related to a structure of fan, particularly a structure of fan which permits dispersion of air flow in 360 degree, and incorporates with a lamp.

Conventionally small fans are used particularly for provision of small air flow. Normally, they do not have any swivel mechanism so that air flow from which is in a fixed direction. Moreover, because of lack of other function, such small fans are of low added value, and their applications are limited. They can not satisfy the need of consumers today who prefers to use products with diversified functions.

In view of the drawback of the conventional jack packing container, the inventor has developed a structure of fan, and it includes mainly a conical guide in the upper protection cover of the fan to guide air flow in 360 degree, an appropriate lighting element and a set of batteries in the guide, and a push-button switch in the center of the upper protection cover to turn on and off the lighting element. Moreover, an appropriate quantity of cotton is placed to provide aromatic smell during operation of the fan after the cotton is moistened with perfume.

The present invention will be described below in detail by way of example with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of a fan according to the present invention.

Fig. 2 is a sectional view of the fan according to the present invention.

Fig. 3 is a perspective fragmental view of the fan according to the present invention.

Fig. 4 is a perspective fragmental view of a lamp hood and a guide plate according to the present invention.

As shown in Figs. 1 to 3, the present invention comprises mainly a base (1), a fan (2), an upper protection cover (3), a lower protection cover (4), a lamp hood (5), and a guide (6).

The base (1) has a bottom plate (11) which is fixed to the base by means of bolts (12). A footing pad (13) is fitted to the end of each bolt (12). Within the base a plurality of batteries (14) are placed. A fan control switch (15) and a LCD clock (16) are placed on the base (1) the appropriate positions. A movable battery chamber cover (17) is designed on the bottom plate (11) to ease loading and unloading of the batteries (14). A d.c. socket (18) is located at a side of the base of that a.c. current via an a.c. to d.c. transformer can be used as power source.

The fan (2), incorporated with a motor (21), is same with the in the prior arts, and no description for which will be given here.

The upper protection cover (3) is in the form of a circular grille composed of a plurality of circular ribs of different diameters, and has a locking element (31) at its circumference. A plurality of fixing elements (32) are designed at the inner edge of a selected rib at appropriate intervals. The upper protection cover (3) has a hole (33) at the center, and connecting element (34) at a side opposite to the locking element (31) for fitting to the lower protection cover (4).

The lower protection cover (4) is formed with a plurality of ribs to form a guard, and has a motor fitting hole (41) at the center.

The lamp hood (5) is in the form of a disk having a push-button switch (51) in the center.

The guide (6) is in the form of a conical structure with a plurality of pinch hooks (61) arranged at appropriate intervals on the edge of its open end. It has a battery chamber for batteries (63) at another end.

The batteries (63) are connected to the push-button switch (51) with two conducting wires (64). The guide (6) is designed so as the lamp hood (5) is fixed to its open end by means of bolts (66) from the respective screw holes at the surface of the guide (6) and their corresponding screw holes on the lamp hood (5).

For assembly of the present invention, the guide (6) is fixed to the upper protection cover (5) by engaging the pinch hooks (61) with the fixing elements.

The guide (6) is then secured that by outward extending tendency exerted by elasticity of its material, such as plastic material. Air flow from the fan can b dispersed for 360 degree by guiding effect of the conical surface of the guide (6). Therefore, there is a special 360 degree air blowing effect. Since the pushbutton switch (51) is located at the center (33) of the upper protection cover (3), a light can be provided at the top of the fan when the push-button switch (51) is pushed to turn on a lighting element (62). Furthermore, the lamp hood (5) and the guide (6) can be removed from the assembly to become an independent lighting fixture.

A suitable quantity of cotton or other waterabsorptive material can be placed within the guide, and the lamp hood (5) can be designed with a plurality of slots (53) to form a plurality of openings (67) after assemble of the guide (6) and the lamp hood (5) as shown in Fig. 4. Then, perfume can be poured through the openings (67) and absorbed by the cotton so that an aromatic smell can be dispersed to the environments by operation of the fan.
