Description

Hair dryer

The utility model relates to haircut or the equipment of having a shave, particularly hair drier and annex thereof.

Existing hair dryer, its power line and plug are many draws from handle, this power line is an equal length, can only stack up when not using or on hair-dryer, and pretty troublesome, also very inconvenient, in use, the place to use is different apart from the distance of socket, has more one section line sometimes, La Laila goes, and is also very inconvenient.

The purpose of this utility model provides a kind of power line can being packed up also can make it stretch out the hair dryer of random length.

The purpose of this utility model realizes by following technical scheme, hair dryer has casing, back cover, electric heater, motor, impeller, the mounting of supporting motor, power line, the plug of power line one end, circuit control system is characterized in that being fixed with support on the said mounting, is fixed with axle on the support, on the axle rotating cylinder is arranged, one end is housed in the cylinder is fixed in axle, the other end is fixed in the disc spring of cylinder inboard, and said power line all is around on the cylindrical of cylinder when disc spring loosens, one side of cylinder is fixed with big brush ring and little brush ring, on support, be fixed with the big contacted long brush of brush ring and with the contacted short brush of little brush ring, the cylinder end of power line is with big, little brush ring is connected, and also has little axle on support, index drum ratchet that rotates and the spring that suppresses ratchet are arranged on the little axle, ratchet has the braking limit and presses the limit, has the projection that acts on mutually with the braking limit on the cylinder, also has the take-up button of the control ratchet that is loaded on the housing.

When disc spring loosens, power line should be all on cylinder, cylinder is controlled one-directional rotation by ratchet, pressing the button cylinder with hand could be reversed by spring action, when with pulling moving power line, power line is extending, simultaneously because the effect of ratchet, cylinder stops on the several position that projection is arranged of every circle, power line can stretch out certain-length on demand and rest on this length, press the take-up button with hand, power line is promptly recoverable, has big or small brush ring and length between cylinder and support, short brush, electric power still can be sent to control system and deliver to motor and electric heater when cylinder rotates, therefore this hair-dryer solved hair dryer not the time spent power line need stack, the improper and dilatory on the ground phenomenon of power line length is used very convenient during use.

Below in conjunction with drawings and Examples hair dryer of the present utility model is done detailed explanation.

Fig. 1 is the structural representation of the utility model hair dryer;

Fig. 2 is the cutaway view Amplified image of the utility model hair dryer along A-A face among Fig. 1;

Fig. 3 is the cutaway view Amplified image of the utility model hair dryer along B-B face among Fig. 2.

As Fig. 1, Fig. 2, this hair-dryer have casing 1, back cover 14, and they fix with screw

As Fig. 1, Fig. 2, this hair-dryer has casing 1, back cover 14, they fix the shell that forms the hair-dryer with air outlet and handle with screw, electric heater 2 is housed in shell 1, motor 3, impeller 5, motor 3 is by mounting 4 supportings, also has attaching plug 24, power line 22 and circuit control system 21, above handle, has support 6, support 6 is fixed on the mounting 4, be fixed with axle 13 on the support 6, the rotating cylinder 11 that is equipped with on the axle 13, axle head is fixed with baffle plate 15, cylinder 11 can not deviate from, cylinder is made up of left-hand cylinder 7 and right tube 12, connect with the seam location and with screw 17 at the middle part, therefore the core of cylinder can carry out the operation to the power line end when taking apart, big brush ring 9 and little brush ring 18 are housed on the web outside of left-hand cylinder, electric wire in the hole 10 of the tube plate of cylinder 11, introduce back two lines respectively with greatly, little brush ring is connected, on support 6, be fixed with long brush 8 and short brush 19, they join with big brush ring 9 and little brush ring 18 respectively, by length, short brush is guided power supply into power control system again, therefore when being wound with power line on the cylinder and rotating, power supply still can be introduced hair dryer, power line 22 is drawn on cylinder and by the handle, at its lower end of casing 1 back cover 14, there is plug 24 end, in the exit of power line 22 flaring guidewire port 23 can be arranged also, in casing 1 back cover 14 guide roller 20 can be arranged, so that the pulling out or be involved in of electric wire, inside at right tube 12 has a disc spring 16, and the inner of spring 16 is connected with axle 13, the outer end then is connected mutually with right tube inboard, be fixed with baffle plate 15 in the end of axle 13, it can not drop cylinder on axle 13, and can be in order to be screwed into the fixedly screw of back cover 14, mounting 4, support 6, two side plates of cylinder 11 should be (as the Fig. 2) that can ventilate, so that impeller 5 air-supplies.

Fig. 2, Fig. 3 shows the controlling organization of cylinder 11, it comprises the little axle 26 that is fixed on the support 6, on the little axle 26 rotating ratchet 28 is housed, ratchet has braking three arms of angle 31, it is vertical with the hole that penetrates little axle, and be positioned on centre of the drum's line or center line slightly by last, three arms of angle have a hypotenuse and a straight flange, ratchet also has parallel with a little axis hole limit 32 that presses, the projection (or muscle) 30 that on left-hand cylinder 7 side plates, has several (for example 4-6) circumference uniform distribution, brake three arms of angle 31 and stretch into projection 30 by spring 27 effects, take-up button 29 is stuck on the casing 1 and acts on and presses on the limit 32, when pressing the button 29, ratchet 28 rotates and makes around little axle 26 brakes the position that projection 30 is left on limit 31, and release button is then braked the position that the limit changes projection 30 again over to.

The effect of the take-up that this hair dryer has is as follows, when spring 16 loosens fully, power line should be able to be all on cylinder 11, when with pulling moving power line when power line is stretched out, cylinder is drawn and is rotated, and then spring 16 is by rolling-in, projection 30 on the left-hand cylinder 7 acts on the hypotenuse on braking limit 31 simultaneously, ratchet can be promoted resilience and cylinder is not locked, when pull the wire not, spring 16 makes the cylinder revolution, its 30 of projection is stuck on the straight flange of three arms of angle, can not promote ratchet 28 resiliences, thereby cylinder is locked, so cylinder all has several latched positions at every circle, pull out power line to suitable length, let go when not drawing, then power line can be parked in suitable length, when desire income power line, press the take-up button, brake three arms of angle and leave projection 30, then cylinder returns back to the final position, power line all can be packed up.

Hair dryer of the present utility model, power line all can be taken in hair dryer, to how long also can be fixed on this length with how long line being pulled out, when need are regained power line, press the take-up button, power line gets final product automatic drawing back, can avoid not the time spent power line to push away putting and dilatory, very convenient on the ground when using.
