The front end of socket part 11 is no more than tunnel inlet 51 backward in the axial direction.Specifically, as shown in Figure 1, in the present embodiment,
The mating part 11 is at least partly more than tunnel inlet 51 forward on the direction perpendicular with central axis X.Specifically, can will in
Heart axis X is defined as axis of abscissas, tunnel inlet 51 the side perpendicular with central axis X be upwardly formed with axis of abscissas phase
The straight line of friendship is defined as axis of ordinates, and the point that axis of abscissas intersects with axis of ordinates is origin, and the front end of mating part 11 is in
The numerical value of the abscissa of projection in heart axis X is always more than 0.Wherein, when mating part 11 be arranged to central axis X phase
When on vertical direction being at least partly more than forward tunnel inlet 51, the setting of the position of mating part 11 is not unique.It is set forth below
Main several plans of establishment:
First, mating part 11 can be arranged in the bottom (as shown in Figure 1) of host shell 10, when battery pack 40 is coupled to this
When mating part 11, battery pack 40 and handle 70 both sides that be located at power plant 30 opposite.Preferably, when battery pack 40 is coupled to this
When mating part 11, battery pack 40 and projection of the air intake space 55 on the direction perpendicular with central axis X are least partially overlapped
(as shown in Figure 1).It is further understood that being, a part for mating part 11 is presented axially in the rear side of tunnel inlet 51, another
Part is presented axially in the front side of tunnel inlet 51.The design scheme of 11 position of mating part, can make entire power tool
For 30 center of gravity closer to rear end, operator is easier to lift machinery operation, and when long working is not easy to feel fatigue.It is more excellent
Choosing, when battery pack 40 is coupled to the mating part 11, the front end of battery pack 30 and the front end of handle and central axis X phase
Flush on vertical direction.So design, integrally-built lines are not mixed and disorderly, and the weight layout of hair-dryer 100 is also more reasonable,
It is man-machine more preferable.
Secondly, in another design, mating part 11 and the same side of 70 centrally disposed axis X of handle (are such as schemed
3, shown in Fig. 4).Mating part 11 and the in axial direction upper front and back setting of handle 70.So design, on the one hand, greatly reduced
The space that complete machine is occupied in the vertical direction, on the other hand, power plant 30 are arranged against the lower-left end of handle 70, battery pack 40
Upper right side against handle 70 is arranged, and power plant 30 is arranged against handle 70 with battery pack 40 so that weight is concentrated, i.e., heavy
The position that the heart is held closer to i.e. hand so that hold more comfortable, when long-time gripping handle 70 is not easy to feel fatigue.
In addition, also a kind of scheme, mating part 11 is arranged in the left side in symmetric handles face or right side (such as Fig. 5~Fig. 7 institutes
Show).When considering that operator carries machine, the diametrical degree of balance of complete machine, it is preferred that mating part 11 is equipped with 2.At this point, with
The quantity of the matched battery pack 40 of socket part 11 is also 2.2 battery packs 40 are selectable to be coupled to corresponding mating part 11,

When battery pack is combined with corresponding mating part, the plane of symmetry of 2 40 opposite handles of battery pack is axisymmetricly arranged.So design,
Not only extend the power-on time of battery pack 40, and makes complete machine that can reach balance radially.In addition, 2 mating parts 11 is last
End is no more than tunnel inlet 51 backward in the axial direction, and when battery pack 40 can be prevented to be coupled with mating part 11, battery pack 40 is blocked
The opening of air intake space 55 hinders air flow direction air intake space 55 and enters in air duct portion 50.Further, in this scheme,
Since the bottom of host shell 11 does not have blocking for component, in order to increase intake, the bottom of host shell 11 with into
The opposite region in wind space 55 is also provided at least one hollow-out parts (not shown), and the hollow-out parts are connected with air duct portion 50
It is logical.Air-flow can not only be flowed into from the left and right side direction perpendicular to symmetric handles face, can also be from the bottom of host shell 11
Hollow-out parts flow into and then ensure that intake.Certainly, in order to prevent machine startup when, the hand of operator accidentally stretches into hollow-out parts,
The size of the hollow-out parts is limited, and ensure that intake while ensureing that operator is safe.
