Specific embodiment

The utility model is described in further detail below in conjunction with figure embodiment.

As shown in Figures 1 to 4, in the present embodiment without leaf hair dryer, mainly include the crust of weathering 1, handle 2, driving mechanism 3, Fan blade 4, baffle 5, lamp 6, filter screen 9.Certainly this without in leaf hair dryer also include control circuit board in the prior art, switch, The existing structures such as power supply line.

Wherein the crust of weathering 1 includes inner casing 11, shell 12 and housing 13, and inner casing 11, shell 12 are in a tubular form.And inner casing 11 is in It is horn-like, it is gradually increased from diameter after preceding value.Shell 12 is set in outside inner casing 11, and the formation of shell 12 can according to need setting It is various streamlined with aesthetic effect.Housing 13 then covers the rear end for being connected to inner casing 11, shell 12, which is in Ring-type, i.e. housing 13 a edge are connect with inner casing 11, another edge is connect with shell 12, and then cover 11 He of inner casing The opening of rear end between shell 12.And the opening of front end then constitutes air outlet 102, air outlet 102 between inner casing 11 and shell 12 On be provided with cricoid filter screen 9 to support the positioning between inner casing 11 and shell 12.And space between inner casing 11 and shell 12 Cricoid air-out passage 101 is then constituted, the inside of inner casing 11 then constitutes air intake passage 103.Also it is between inner casing 11 and shell 12 Divergent shape is provided with multiple guide pins 8, and air-out passage 101 is isolated into a plurality of axially extending air-guiding aisle by these guide pins 8 1011.Fan blade 4 is mounted in 101 space of air-out passage between two guide pins 8.And the rear end of air-out passage 101 is then formed The air-inducing passage 1012 for being connected with 4 installation space of fan blade and being connected with each air-guiding aisle 1011.

An oral area is offered on inner casing 11, corresponding strainer 1041 also can be set on the oral area, which is then constituted Air inlet 104.In order to guarantee the intake of air inlet 104, then in front opening covering one baffle 5 of setting of inner casing 11.Resistance Only the baffle 5 in the present embodiment is using plate body made of transparent material, such as acrylic board, so that baffle 5 has translucency.

Handle 2 includes the first half-shell 21 and the second half-shell 22 for capableing of pairing connection.First half-shell 21 and the second half-shell 22 Between constitute an installation space, driving mechanism 3, control circuit board are then mounted in the space in handle 2.And it switchs and then installs It is connected on handle 2, and with control circuit board, sends switch and gear signal to circuit board.Power supply line then penetrates handle 2 It is interior and be connected in control circuit board, the power supply without leaf hair dryer is then able to achieve after power supply line connection external power supply.This implementation Driving mechanism 3 in example uses motor, and the various mechanisms with driving effect in the prior art can also be used.

In the present embodiment, first half-shell 21 upwardly extends the first fixed part 211 that can be set in 1 front of the crust of weathering, the Two half-shells 22 upwardly extend the second fixed part 221 that can be set in 1 rear portion of the crust of weathering.Pass through the first fixed part 211 and second Fixed part 221 enables stronger steadily realize with the crust of weathering 1 of handle 2 to connect, when installation, when necessary without using screw Etc. fixation members, it is easy for installation, while shape is more beautiful.

In order to guarantee hair dryer, in driving mechanism 3, the outlet air in the case where output power is certain is larger, it will usually increase wind The size of leaf 4.The size for expanding fan blade 4 in the present embodiment opens up an installing port in the lower part of shell 12, the installing port On bracket 7 is installed, bracket 7 forms the cavity of oriented 2 sunken inside of handle, and driving mechanism 3 is fixedly mounted in handle 2 and leans on The place of 4 installation site of nearly fan blade, the driving end of driving mechanism 3 are extend out in cavity from bracket 7, and fan blade 4 is mounted on cavity Driving end that is interior and being connected to driving mechanism 3.The position that the fan blade 4 corresponds to air inlet 104 simultaneously is installed, and air-flow is accelerated Flowing.

The front end of bracket 7 has also upwardly extended plank in the present embodiment, the plank and the guide plate positioned at 4 two sides of fan blade Front end closure connection, so entering the air-flow in air-out passage 101 from air inlet 104 then can be rearwards into air-inducing passage It in 1012, and then enters in each air-guiding aisle 1011, and then is blown out from air outlet 102 further along.

In addition, the lamp 6 in the present embodiment uses LED light 6, which is mounted on the position on bracket 7 and being located at 5 outer rim of baffle It sets, so when LED light 6 carries out color change according to the different working condition of hair dryer, different colors may be displayed on gear It on plate 5, is user-friendly for observing, in this way, can quickly judge the current state of hair dryer, and then user is facilitated to adjust Section.

Air inlet 104 is arranged in the crust of weathering 1 on the inner wall of air intake passage 103 without leaf hair dryer for this, so that from the crust of weathering 1 Inner wall in enter the wind, the air of entrance under the action of fan blade 4 by air-out passage 101 from air outlet 102 blow out, the process In, air-flow needs not move through the motor as driving mechanism 3, then will not be in air-flow by the dust that carbon brush generates in the motor course of work Drive under blown out through air outlet 102, reduce pollution of the hair dryer internal structure to air-flow, improve the cleannes of outlet air, And then the user experience is improved.
