In addition, connecting portion 40 not only acts as connection function, the entity of connecting portion 40 between joint portion 30 and air channel portion 20
Structure is in the Crack cause that the extension for being roughly parallel to central axis M directions is admission space 64, while the entity of connecting portion 40
Structure does not close admission space 64, and specifically, the entity structure of connecting portion 40 makes admission space 64 in the big of central axis M
It is unlimited on partially radially.
It should be noted that for central axis M, the definition of radial direction is virtual using central axis M as one
The central shaft of cylinder, the radial direction of the imaginary circles cylinder be it is referred herein go out radial direction, and radial direction here is not
Singly refer to some direction and refer to the set of some directions composition.The entity structure of connecting portion 40 is present in the imaginary circles cylinder
Some circumferential positions, except some radial directions corresponding with these circumferential positions（Set partially radially）Outside, at remaining radially
（The set of another part radial direction）Enterprising headroom 64 is unlimited.
In order to ensure air quantity, the part occupied by the entity structure of connecting portion 40 should be much smaller that connecting portion 40 makes air inlet empty
Between 64 unlimited parts, so as a whole, admission space 64 is radially unlimited, air-flow energy edge central axis M's
Central axis M radial inflow into admission space 64.
When connecting portion 40 is only made up of an entity structure, such as when being only made up of top connecting portion 41, admission space 64
Except sentence external central axis M where the entity structure is radially unlimited everywhere.
When connecting portion 40 is made up of two different entity structures, for example, top connecting portion 41 and base connecting portion 42 or
It is individual independent of each other between them during several middle ribs 43, now each entity knot of connecting portion 40 in other words
Structure is discontinuous in central axis M circumference, then now admission space 64 is except the entity of these composition connecting portions 40
The external central axis M's of structure is radially unlimited everywhere.
Preferably, the respective occupied circle of the entity structure independent in central axis M circumferences of connecting portion 40
All radians should be less than 30 degree, and the circumference arc of connecting portion 40 each entity structure occupied by central axis M circumferences
Summation should be less than 90 degree, can so ensure circumference arc of the unlimited part of admission space 64 in central axis M circumferences
90 degree can be more than or equal to, and then ensure that the intake of admission space 64.
Preferably, the housing 10 of hair-dryer 100 is further also formed with the handle portion 50 gripped for user.Typically
For, handle portion 50 has a split S（As shown in Figure 2）, the handle portion 50 is generally symmetrical with respect to split S,
And admission space 64 could be arranged to be unlimited on vertical split S direction.Because in general, user is from handle
The top in portion 50 grips to it, and handle portion 50 is symmetrical relative to split S, and the direction perpendicular to split S is
For left and right directions, admission space 64 left and right directions be it is unlimited can guarantee that user grip handle portion 50 hand will not influence very much into
The intake of headroom 64.
Based on such purpose of design, as a kind of preferred scheme, by the one of handle portion 50 and the entity structure of connecting portion 40
The centrally disposed axis M in part same circumferential position, handle portion 50 are located at connecting portion 40 therewith for central axis M
The outside of corresponding entity structure.
In order to ensure the structural strength of handle portion 50, handle portion 50 can not be too thin, therefore can will be wide in connecting portion 40
Spend size（That is the size of left and right directions or the size perpendicular to split S directions）The entity structure and handle of a maximum part

For above-below direction, although top connecting portion 41 and base connecting portion 42 are respectively arranged at the top of admission space 64
And lower section, but be to have one in the lateral direction because air channel portion 20 forms the part of tunnel inlet 211 and joint portion 30
Fixed width degree, and their width is bigger than the width that top connecting portion 41 and base connecting portion 42 actually take up space（Fig. 2
Although center base connecting portion 42 is most left to have certain width to most right, it is the frame structure of middle opening, be that is to say
Say the width shared by the entity structure of base connecting portion 42 and little）, so in the vertical direction, admission space 64 is also to open wide
's.
Similar, although rib 43 or so is set among two, they only play a part of connection, and they are upper
Size occupied by the upward reality in lower section is also extremely limited, therefore admission space 64 is also what is opened wide in the lateral direction.
In general, divide them although admission space 64 is supported by connecting portion 40 between air channel portion 20 and joint portion 30
From into and the size of actually admission space 64 is determined by the size of the tunnel inlet 211 in air channel portion 20.First, even
The each several part of socket part 40 is formed in the outside of tunnel inlet 211 with air channel portion 20 and connected, while connecting portion 40 connects greatly to realize
Cause is extended along the direction parallel to central axis M, so the size of tunnel inlet 211 determines admission space 64 at center
The sizes of axis M radially.In addition, according to the demand of the air quantity of hair-dryer 100, admission space 64 needs in the axial direction to ensure necessarily
Size, it so just can guarantee that air intake efficiency and obtain required wind.
As a kind of preferred scheme, the length direction of handle portion 50（Refer to the side of the both ends line of the ultimate range of handle portion 50
To）Split S is parallel to, or perhaps parallel to perpendicular, then admission space 64 is spacious in the lateral direction

Between be additionally provided with middle rib 43, but because air-flow is can to enter air inlet sky along perpendicular to the direction of perpendicular
Between 64, so admission space 64 between top connecting portion 41 and base connecting portion 42 it is also assumed that be unlimited.From the opposing party
For, if the entity structure that continuously direction is completely covered without formation in one direction for connecting portion 40, makes air-flow
Admission space 64 can not be entered along the direction and needed if bypassing the entity structure along other directions, be considered as admission space
64 in the direction be unlimited.
