BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electrical depilator, in particularly, to an electrical depilator which is easy in die sinking, convenient in assembling, and of low cost.

2. Description of the Related Art

There are various electrical depilators with different constructions in conventional technology and there are a great many patents relating to depilators.FIG. 1shows a type of depilator among conventional ones. The depilator comprises a main body1′, a motor2′, a reduction gear set3′, an arcuate shaft4′, a set of base pieces5′ and thin clipping pieces6′. Each clipping piece6′ is fixed on a corresponding base piece5′, that is, the thin clipping piece6′ is supported on and driven by the base piece5′ to move correspondingly. The whole set of base pieces5′ are coupled together by shifting yokes (not shown, or by bearing housings or shaft pins) so as to rotate synchronously. The whole set of base pieces5′ and the thin clipping pieces6′ are fitted over the arcuate shaft4′ which is supported on a shaft seat of the main body1′. A first stage gear of the reduction gear set3′ meshes with a driving wheel of the motor2′, and a last stage gear is fixed on the base piece5′ which is located at the endmost position.

When it is energized, the driving wheel of the motor2′ drives the whole set of base pieces5′ and the thin clipping pieces6′ supported on the base pieces5′ through the reduction gear set3′ to rotate around the arcuate shaft4′. Thereby, the clipping pieces6′ on the gradually-narrowed side of the arcuate shaft4′ are caused to perform a clipping action by the way of being pressed by the base pieces5′, and those on the gradually-widened side of the arcuate shaft4′ perform a loosening action. Thus, hairs are depilated rapidly on the gradually-narrowed side of the arcuate shaft4′ by the clipping pieces6′, while the depilated hairs are thrown into the hair-collecting box on the gradually-widened side of the arcuate shaft4′. Therefore, such depilator can depilate hairs rapidly.

However, it can be readily appreciated that the above-mentioned depilator has the following disadvantages after a close study of its structure.

The depilator comprises a plurality of base pieces5′ performing pressure transfer and motion functions and thin clipping pieces6′ supported by the pieces5′ and performing a hair clipping function. In addition, the plurality of base pieces5′ and the clipping pieces6′ are arranged alternately in the following manner: one base piece5′→two thin clipping pieces6′→one base piece5′ . . . and so on. Thus, there are too many members, which need die sinking not only for forming base piece5′ but also for forming thin clipping pieces6′. Therefore, it is difficult in die sinking. Furthermore, the cost of manufacture is high because the structure of the depilator is complicated and the thin clipping pieces6′ are generally made of metals. Moreover, the assembling procedure is very troublesome because of the alternate arrangement in the form of one base piece5′→two thin clipping pieces6′→one base piece5′ . . . and so on.

SUMMARY OF INVENTION

In view of the above disadvantages in the conventional art, it is an object of the present invention to provide an electrical depilator which is easy in die sinking, convenient in assembling, and of low cost.

In order to achieve one or more aspects of the above object, the present invention provides the following technical schemes:

An electrical depilator, comprising substantially a main body, a motor, a reduction gear set, an arcuate shaft and a set of single-pieces. The arcuate shaft is supported on a shaft seat of the main body. A first stage gear of the reduction gear set meshes with a driving wheel of the motor, and a last stage gear is fixed on the single-piece which is located at the endmost position. Each single-piece has a clipping surface and a supporting portion. The whole set of single-pieces are arranged with the clipping surfaces opposite to each other. A clipping gap is formed between the opposite surfaces of two single-pieces. The whole set of single-pieces are coupled together by fixing members to rotate synchronously. The whole set of single-pieces are fitted over the arcuate shaft all together.

The fixing members are shifting yokes which are formed on both sides of each single-piece. One shifting yoke on a single-piece is inserted into and locked with another shifting yoke of an adjacent single-piece, thus the whole set of single-pieces are coupled together and rotated synchronously.

The fixing members are fork bodies which are provided with shaft holes at centers thereof corresponding to the position of the arcuate shaft. Each single-piece is provided at both sides with fork shaped slots. Both sides of each fork body are inserted into and locked with two fork shaped slots of two adjacent single-pieces, thus the whole set of single-pieces are coupled together and rotated synchronously.

A thin piece is fixed on each fork body. The thin pieces and the fork bodies, together with the whole set of single-pieces, are fitted over the arcuate shaft. The thin piece is provided between two opposite clipping surfaces of two single-pieces, and two clipping gaps are formed between both sides of each thin piece and clipping surfaces of two single-pieces, respectively.

The fixing members are bearing housings. The whole set of single-pieces are coupled together by the bearing housings to be rotated synchronously.

The fixing members are shaft pins. The whole set of single-pieces are coupled together by the shaft pins to be rotated synchronously.

With the above structure, when energized, the driving wheel of the motor drives the whole set of singe-pieces through the reduction gear set to rotate around the arcuate shaft. Thereby, the single-pieces on the gradually-narrowed side of the arcuate shaft are caused to perform a clipping action, and those on the gradually-widened side of the arcuate shaft perform a loosening action. Thus, hairs are depilated quickly on the gradually-narrowed side of the arcuate shaft directly by use of the clipping surfaces of the singe-pieces, so as to depilate hairs quickly.

The electrical depilator according to the present invention has the following advantages over the prior arts. The depilator only has a plurality of single-pieces. That is, the two types of pieces in the conventional art, i.e. the base pieces performing pressure transfer and motion functions and the thin clipping pieces supported by the pieces and performing a hair clipping function, are simplified as one type of single-pieces. As a result, the thin clipping pieces are eliminated. Thus, the number of members is reduced, which facilitates the die sinking because only the die for forming single-pieces is needed. In addition, the structure is greatly simplified and only the single-pieces are required to be assembled in assembling. Therefore, the assembling procedure is easy and the cost is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will be described in detail with reference to attached drawings.

As shown inFIG. 2in conjunction withFIG. 3, an electrical depilator according to one preferred embodiment of the present invention comprises a main body1, a motor (not shown), a reduction gear set3, an arcuate shaft4and a set of single-pieces5.

The arcuate shaft4is supported on a shaft seat11of the main body1.

A first stage gear31of the reduction gear set3meshes with the driving wheel (not shown) of the motor, and a last stage gear32is fixed on the single-piece5which is located at the endmost position.

Each single-piece5has a clipping surface51and a supporting portion52, as shown inFIGS. 4-8. The whole set of single-pieces5are arranged in such a manner that the clipping surfaces51are opposite to each other. A clipping gap A is formed between the opposite surfaces51of two single-pieces5, as shown inFIGS. 2 and 3. The whole set of single-pieces5are coupled together by fixing members so as to rotate synchronously. The fixing members can have a variety of specific structures. As shown inFIGS. 4-8of this embodiment, the fixing members are shifting yokes53which are formed on both sides of each single-piece5. One shifting yoke53on each single-piece5is inserted into and locked with another shifting yoke53on the adjacent single-piece5, thus the whole set of single-pieces5are coupled together and rotated synchronously. In another embodiment, the fixing members can also be fork bodies54shown inFIG. 14which have three fork feet542respectively and are provided with shaft holes541at centers thereof corresponding to the inserting position of the arcuate shaft4. As shown in conjunction withFIGS. 12 and 13, each single-piece5is provided at both sides thereof with fork shaped slots501. Both sides of each fork body (that is, the three fork feet542) are inserted into and locked with two fork shaped slots501of two adjacent single-pieces5, thus the whole set of single-pieces5are coupled together and rotated synchronously. The fixing members can also be bearing housings which are not shown in drawings, by which the whole set of single-pieces5are coupled together and rotated synchronously. The fixing members can also be shaft pins which are not shown in drawings, by which the whole set of single-pieces5are coupled together and rotated synchronously. Referring toFIGS. 9 and 11, the whole set of single-pieces5are fitted over the arcuate shaft4all together.

To facilitate the assembling of the single-pieces5in the set, in the embodiment, firstly the whole set of single-pieces5are mounted on the shaft seat11by the arcuate shaft4and are fixed by a spring6. Then the arcuate shaft4, the reduction gear set3and the shaft seat11are covered by a shell12, only the whole set of single-pieces5are exposed for depilating. Therefore, the depilator has a good appearance, as shown inFIG. 10.

With the above structure according to the present embodiment, when energized, the driving wheel of the motor drives the whole set of singe-pieces5through the reduction gear set3to rotate around the arcuate shaft4. Thereby, the singe-pieces5on the gradually-narrowed side of the arcuate shaft are caused to perform a clipping action, and those on the gradually-widened side of the arcuate shaft perform a loosening action. Thus, hairs are depilated on the gradually-narrowed side of the arcuate shaft directly by use of the clipping surfaces of the singe-pieces5so as to depilate hairs quickly. Two types of pieces in the conventional art, i.e. the base pieces5′ and the thin clipping pieces6′, are simplified as a type of single-pieces in the present invention, with the thin clipping pieces6′ being eliminated. Thus, the number of members is reduced, which facilitates the die sinking because only the die for forming single-pieces5is needed. In addition, the structure is greatly simplified and only the single-pieces5are required to be assembled during the assembly process. Therefore, the assembly is easy and the cost is reduced.

As shown inFIGS. 15-16, a thin piece55is fixed on each fork body54shown inFIG. 14according to yet another embodiment of the present invention. The thin pieces55and the fork bodies54, together with the whole set of single-pieces5, are fitted over the arcuate shaft4. The thin piece55is provided between two opposite clipping surfaces51of two single-pieces5, and two clipping gaps A are formed between both sides of each thin piece55and clipping surfaces51of two single-pieces5, respectively. (That is, the gap A inFIG. 2is divided into two parts.) Compared with the conventional art, two thin pieces are eliminated in this embodiment. Therefore, it is easy in die sinking, convenient in assembling, and of low cost. In addition, compared with the above two embodiments, this embodiment has twice the gaps with further introducing only one thin-piece55. Thus, it has a better performance of depilating.
