Abstract

The utility model provides an improved structure for the switch of an electric fan, comprising a casing body, a push type switch, a hole seat, and a knob, wherein, the casing body can be arranged on the foot seat of the electric fan or other positions; the push type switch is arranged in the holding chamber of the casing body; a push key is arranged on the push type switch; the hole seat and the casing body are of an integral forming; the hole seat is positioned on the side edge of the push type switch; the rotary shaft of the knob is clamped in the hole seat; the other end of the rotary shaft has a priming arm which is eccentric; one side of the priming arm has a long groove for the sheathing of the push key of the push type switch. The priming arm is displaced within an arc by the rotation of the knob to drive the push key to be displaced, and switching and speed changing can be realized.

Description

Improved structure of switch for electric fan

The utility model relates to a kind of Switch for electric fan structure-improved, refers to a kind of Switch for electric fan structure-improved that can reduce operational failure rate and switch cost that has especially.

Habitual Switch for electric fan roughly divides two kinds:

(1) pushing-type switch, cost is comparatively cheap, but in use, must promote with (or about) about shuttle, and suffered thrust is very big, easy break-down, promptly its using character is unstable, and useful life is shorter.

(2) rotary switch, cost is higher, is about a times of pushing-type switch, but in the use, because of revolving force less and soft, easy break-down not, promptly its using character is comparatively stable, and useful life is longer, thereby generally adopted by dealer institute.

Main purpose of the present utility model is to provide a kind of Switch for electric fan structure-improved that reduces operational failure rate and cost.

Feature of the present utility model then is: borrow the rotation of knob, the priming arm that makes an off-centre be located at the knob rotating shaft other end is done the arc displacement, to reach effects such as reducing operational failure warp and switch cost.

A kind of Switch for electric fan structure-improved for realizing that the purpose of this utility model proposes comprises:

One housing can be installed in electric fan runners or other appropriate positions;

One pushing-type switch can be installed in the room of this housing, has a push button on it; And

One hole seat, itself and housing are one-body molded, and are positioned at the side of pushing-type switch, and are positioned at the hull outside end face and have some teeth of pulling;

One knob, its rotating shaft penetrate in this hole seat, and the centre has a ring wedge-shaped impression, so that locate with clip tooth clip;

The other end that it is characterized in that this knob rotating shaft has one and slightly is long ellipticity and eccentric priming arm, one side of this priming arm has the elongated slot of an ovalize, can be inserted in for the push button of pushing-type switch, to borrow the rotation of knob, make the priming arm form the arc displacement, and then about the drive push button (or about) straight-line displacement, and changeable speed change, to reach effects such as reducing operational failure rate and switch cost.

For reaching above-mentioned purpose, the technological means of described usefulness and effect thereof are lifted now with next preferable possible embodiments about the utility model, and details are as follows for conjunction with figs., in order to understanding and approval.

Fig. 1 is the three-dimensional exploded view of the utility model embodiment;

Fig. 2 is the assembled sectional view of the utility model embodiment;

Fig. 3 is the action schematic diagram of the utility model embodiment.

As shown in drawings, the utility model construction of switch comprises: a housing 1 can be installed on electric fan runners or other appropriate locations; One pushing-type switch 2 is located in the room of this housing 2, has a push button 21 on it; One body 3 slightly is convex, and is square internally and round externally shape, is placed on this push button 21; One hole seat 4 is one-body molded with housing 1, and is positioned at the side of pushing-type switch 2, and it is positioned at housing 1 outboard end mask some clip teeth 41; One rotating shaft 5, be inserted in this hole seat 4, the centre has a ring wedge-shaped impression 51, and for clip tooth 41 clips location, the one distal process is for outside the housing 1, and can a sheathed knob 6, the other end then is positioned at housing 1, and has a priming arm 7, and this priming arm 7 slightly is long ellipticity, the elongated slot 71 that has an ovalize on it is to be sheathed on this body 3.

According to above-mentioned tectonic association, promptly shown in Fig. 2 and 3, rotating shaft 5 is to borrow its wedge-shaped impression 51 to be positioned in the hole seat 4 with clip tooth 41 clips, to form the knob rotating shaft, and can rotate with knob 6, priming arm 7 then forms the state of an off-centre with rotating shaft 5, and body 3 and push button 21 just are positioned at elongated slot 71; Therefore, when rotary knob 6, this priming arm 7 will be driven by rotating shaft 5, and form the displacement of a kind of curved (or fan-shaped), so drive body 3 and push button 21 do about the straight-line displacement of (or about), make pushing-type switch 2 can be switched speed change.

In other words, the utility model is to utilize habitual pushing-type switch 2, knob 6 and knob rotating shaft 5, cooperates the ingenious design of eccentric priming arm 7, can make the pushing-type switch be transformed into rotary switch and use; Thus, not only can convert the revolving force of knob 6 to the arc displacement earlier, convert straight-line displacement again to, and make it littler softer, more can further reduce the failure rate that switch uses, the stability and the useful life of promoting its using character; And can reduce the cost of switch significantly, can be rated as one and have progressive and practical creation.

In sum, the concrete structure that the utility model embodiment is disclosed is fully different fully with habitual pushing-type switch or rotary switch, and has absolute novelty; And more can reach the special efficacy that reduces failure rate and switch cost, and have practicality and progressive.

Claims

1, a kind of Switch for electric fan structure-improved comprises:

One hole seat, itself and housing are one-body molded, and are positioned at the side of pushing-type switch, and are positioned at shell outside end face and have some teeth of pulling;

The other end that it is characterized in that this knob rotating shaft has one and slightly is long ellipticity and eccentric priming arm, and a side of this priming arm has the elongated slot of an ovalize, can be inserted in for the push button of pushing-type switch.
