Description

The shake wind structure of hair dryer

Technical field:

The utility model relates to the hair dryer technical field, refers in particular to a kind of shake wind structure that can produce the hair dryer of shake wind.

Background technology:

As everyone knows, hair dryer is extensive use of at present as a kind of haircut fanning tool.General hair dryer can blow out cold wind and hot blast, all is partly and by the heating part that exothermic material is combined into to realize by the air-supply that electro-motor drive fan rotates.Yet under different situations, the user needs different blowing effects, as long wind, shake wind etc., and, do not have specific structure at present to realize, but arbitrarily control by the user for shake wind, thereby the poor effect of shake wind, operation inconvenience.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, can realize shaking automatically the shake wind structure of the hair dryer of wind effect.

Another purpose of the utility model is to provide a kind of air door accurate positioning, does not influence the shake wind structure of hair dryer of the air intake of hair dryer under the normality.

For achieving the above object, the shake wind structure of hair dryer described in the utility model comprises a shake wind seat, the air inlet of this shake wind seat butt joint hair dryer, one air door that rotates is set on shake wind seat, and air door control by an electrical motor driven, and air door is straight with the air intake direction of shaking the wind seat during normality; Insert the control circuit that a location can control the air door normality time stops by a switch SW 1 is in parallel on the main circuit of described electro-motor, this control circuit is provided with a rotary contact type switch SW 2, and this rotary contact type switch SW 2 is followed air door and rotated.

Described rotary contact type switch SW 2 includes contact in an outer contact and, its China and foreign countries' contact is fixed on the outer end of a metal arm, and the inner of metal arm is designed to interior contact, the be connected rotating shaft of air door of metal arm, the position correspondence of contact and interior contact is provided with conductor rail separately outside, conductor rail is molded on the pcb board, two conductor rails are 2 liang of electrodes of rotary contact type switch SW just, outer contact and interior contact rotate on conductor rail separately and slide, and the conductor rail of outer contact correspondence is designed to nonocclusive circular arc.

Be compared with the prior art, the shake wind structure of the hair dryer that the utility model provides, rotate the air intake of controlling hair dryer by air door, obtain the effect of shake wind, air door is controlled by electrical motor driven, shake wind is even, stable, overcomes the unstable defective of existing artificial arbitrarily manufacturing shake wind, increases the practicality of hair dryer; Insert the control circuit that a location can control the air door normality time stops by a switch SW 1 is in parallel on the main circuit of electro-motor, can accurately control the air door location by this control circuit stops, guarantee that promptly the normality lower wind door is straight with the air intake direction of shake wind seat, guarantee the air intake of hair dryer, do not influence other job requirement of hair dryer.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

See shown in the accompanying drawing 1～5 that the utility model comprises a shake wind seat 10, the air inlet of these shake wind seat 10 butt joint hair dryers, so that wind enters hair dryer before earlier through shake wind seat 10.One air door 11 that rotates is set on shake wind seat 10, and air door 11 vertically is installed on the place, air port of shake wind seat 10, and air door 11 drives control by an electro-motor 12, and air door 11 is straight with the air intake direction of shake wind seat 10 during normality.Electro-motor 12 is installed in the downside of shake wind seat 10, and connects the rotating shaft of air door 11 by gear train.Insert the control circuit that a location can control air door 11 normalities the time stops by a switch SW 1 is in parallel on the main circuit of electro-motor 12, control circuit is provided with a rotary contact type switch SW 2, and contact 16 was followed air door 11 rotations in contact 13 reached outside this rotary contact type switch SW 2.

Shown in Fig. 1,2, the outer contact 13 of rotary contact type switch SW 2 is connected the rotating shaft of air door 11 by a metal arm 14, its China and foreign countries' contact 13 is fixed on the outer end of metal arm 14, and the inner of metal arm 14 is designed to the interior contact 16 of rotary contact type switch SW 2, and air door 11 rotating shafts that are connected, interior contact 16 is connected with a utmost point of switch SW 2 by corresponding conductor rail; The outer contact 13 that is fixed on metal arm 14 outer ends is connected with another utmost point of switch SW 2 by corresponding conductor rail; The conductor rail of outer contact 13 is designed to nonocclusive circular arc, and two conductor rails are molded on the pcb board 15, and the two poles of the earth of switch SW 2 are connected in the control circuit.

The connection of rotary contact type switch SW 2 is to be realized by the conductor rail that outer contact 13 and interior contact 16 touch separately simultaneously, in the present embodiment, interior contact 16 is in the state of connecting with corresponding conductor rail all the time, and the conductor rail of outer contact 13 is designed to nonocclusive circular arc, promptly, then can disconnect rotary contact type switch SW 2 in case outer contact 13 rotates to non-conductive rail position.

Shown in Figure 3, switch SW 1 is a two-position switch, when switch SW 1 is connected the main circuit of electro-motor 12, electro-motor 12 gets electric rotation, and rotate by gear train and to drive air door 11 and rotate, air door 11 gyrates and then can change the air port size of shake wind seat 10, promptly change the intake of control hair dryer, so that the air outlet of hair dryer obtains the effect of shake wind.When air door 11 rotates, the outer contact 13 and the interior contact 16 of rotary contact type switch SW 2 are also followed rotation, and because switch SW 1 when connecting the main circuit of electro-motor 12, the control circuit in parallel with it is off-state, at this moment rotary contact type switch SW 2 is in off working state.Disconnect the main circuit of electro-motor 12 and connect control circuit and work as switch SW 1, if at this moment the outer contact 13 of rotary contact type switch SW 2 and in contact 16 when being in simultaneously with corresponding conductor rail on-state, the two poles of the earth of rotary contact type switch SW 2 are in conducting state (shown in Figure 5) at this moment, control circuit then still can be connected the power supply of electro-motor 12 by rotary contact type switch SW 2, electro-motor 12 still rotates, and air door 11 also still rotates.Have only when the outer contact 13 of rotary contact type switch SW 2 forwards non-conductive rail to, the two poles of the earth of rotary contact type switch SW 2 are in off-state at this moment, just thoroughly disconnect the power supply of electro-motor 12 this moment, electro-motor 12 stops at once, air door 11 location just stops (utilizing outer contact 13 to cooperate non-conductive rail design, shown in Figure 1), air door 11 is straight with the air intake direction of shake wind seat 10 when promptly guaranteeing normality, does not influence the air intake work of hair dryer.

When if switch SW 1 disconnects the main circuit of electro-motor 12 and connects control circuit, the outer contact 13 of switching touch switch SW 2 just in time is in non-conductive rail position, the touch switch SW of then transferring 2 the two poles of the earth are in off-state, and electro-motor 12 stops at once, and air door 11 location just stops.
