Abstract

The invention discloses a ceiling fan with telescopic fan blades. The ceiling fan comprises a base, a swing pipe, a rotation disc, connection pieces, first fan blades and second fan blades. One end of the swing pipe is fixed on the base, and the other end of the swing pipe is fixedly provided with the rotation disc; the connection pieces connect the rotation disc and the first fan blades; the first fan blades are hollow structures, and guide grooves and limit grooves are formed in the first fan blades; the second fan blades are hollow structures, and guide blocks and limit blocks are arranged on the outer sides of the second fan blades; the second fan blades are arranged in the first fan blades and fixed on the first fan blades through springs. The ceiling fan is simple in structure, it is guaranteed that the second fan blades are accommodated in the first fan blades under the traction of the springs when the ceiling fan is not in a working state, occupied space is reduced, dust can not easily stain the second fan blades, in work, under the action of centrifugal force, the second fan blades extend out of the first fan blades, the area of the fan blades is increased, and the fanning effect is enhanced.

Description

The scalable ceiling fan of a kind of flabellum

Technical field

The present invention relates to a kind of daily life equipment, relate in particular to the scalable ceiling fan of a kind of flabellum.

Background technique

Ceiling fan is as the common electric of preventing heatstroke and lower the temperature a kind of summer, but present most of ceiling fan is because flabellum is larger, need to take the easy dust of piling up on larger space and flabellum.Along with people are more and more higher to cleaning requirement attractive in appearance, the little household electric appliance that clean, take up room are more and more favored, and foldable ceiling fan is due to installing/dismounting inconvenience.For this reason, we provide a kind of flabellum scalable ceiling fan, have flabellum scalable, are not easy to be stained with ash, and save space.

Summary of the invention

For above-mentioned situation, the object of this invention is to provide the scalable ceiling fan of a kind of flabellum.

The present invention takes following technological scheme to realize: the scalable ceiling fan of a kind of flabellum, comprise base, swing pipe, rotating disk, connecting sheet, the first flabellum and the second flabellum, and described swing pipe one end is fixed on base, and the other end is fixed rotating disk; Described connecting sheet connects rotating disk and the first flabellum; Described the first flabellum is hollow structure, and the inside is provided with guiding groove and restraining groove; Described the second flabellum is hollow structure, and arranged outside has guide pad and limiting stopper; Described the second flabellum is arranged in the first flabellum, is fixed on the first flabellum by spring.

Described guide pad is connected with guiding groove.

Described limiting stopper is connected with restraining groove.

The present invention has following beneficial effect in sum: the present invention has simple in structure, utilize the tractive force of spring to ensure that ceiling fan is received in the first flabellum in the time of off position, minimizing takes up room, be not easy to be stained with ash, when work, under centrifugal action, from the first flabellum, stretch out, expand fan blade area, increase pectinid effect.

Embodiment

As shown in Figure 1, Figure 2 and Figure 3, the scalable ceiling fan of a kind of flabellum, comprises base 1, swing pipe 2, rotating disk 3, connecting sheet 4, the first flabellum 5 and the second flabellum 6, and described swing pipe 2 one end are fixed on base 1, and the other end is fixed rotating disk 3; Described connecting sheet 4 connects rotating disk 3 and the first flabellum 5; Described the first flabellum 5 is hollow structures, and the inside is provided with guiding groove 51 and restraining groove 52; Described the second flabellum 6 is hollow structures, and arranged outside has guide pad 61 and limiting stopper 62; Described the second flabellum 6 is arranged in the first flabellum 5, is fixed on the first flabellum 5 by spring 7.

Described guide pad 61 is connected with guiding groove 51.

Described limiting stopper 62 is connected with restraining groove 52.

Two guiding grooves 51 that two guide pads 61 of the second flabellum 6 arranged outside arrange with a limiting stopper 62 respectively with the first flabellum 5 the insides are connected with a restraining groove 52 is corresponding, when ceiling fan is not worked, limiting stopper 62 makes spring 7 in extended state, be received in the first flabellum 5, both save space, be not easy to be again stained with ash; When work, centrifugal force makes the second flabellum 6 stretch out from the first flabellum 5 the insides along guiding groove 51, expands fan blade area, increases pectinid effect; The design parameter of spring 7 can ensure that the second flabellum 6 can be because centrifugal force flies out, and restraining groove 52 and limiting stopper 62 actings in conjunction provide further protection, even bullet, 7 life-spans, the second flabellum 6 also can not fly out, safe and reliable to after date.

Finally it should be noted that: above embodiment is only in order to illustrate the present invention and unrestricted technological scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the present invention; And all do not depart from technological scheme and the improvement thereof of the spirit and scope of the present invention, all should be encompassed in claim scope of the present invention.
