Detailed description of the invention
As shown in Figure 1 to Figure 3, hair-dryer 100 includes: housing 10, fan 61 and motor 62.Wherein, motor 62 is used for driving fan 61, makes fan 61 rotate around central axis M thus produces air-flow.In order to guide the air-flow that fan 61 produces, housing 10 is formed with air channel portion 20, and this air channel portion 20 is formed with an air channel 21 extended approximately along central axis M, and air channel 21 is flowed to ducting outlet 212 for guiding air-flow by the tunnel inlet 211 in air channel 21.As concrete scheme, fan 61 is arranged in the air channel 21 in air channel portion 20, and tunnel inlet 211 is separately positioned on the two ends that air channel 21 is relative along central axis M direction with ducting outlet 212.
For convenience of explanation, below with the side of tunnel inlet 211 as rear side, with the side of ducting outlet 212 as front side.
Housing 10 is also formed with joint portion 30, joint portion 30 for be combined with the battery bag 63 powered for motor 62 make battery bag 63 can constitute with housing 10 one can together with the entirety that moves.It is said that in general, joint portion 30 is provided with connects the slot 31 of battery bag 63 or track and corresponding electrode connecting piece 32.For the air-flow making joint portion 30 and battery bag 63 not hinder ducting outlet 212 to blow out, joint portion 30 is arranged on the side near tunnel inlet 211, the air channel portion 20, makes tunnel inlet 211 between ducting outlet 212 and joint portion 30.
In order to make air channel portion 20 and joint portion 30 be connected as an entirety and make tunnel inlet 211 can introduce enough air-flows in air channel 21, housing 10 is formed further with connecting portion 40, this connecting portion 40 is respectively connecting to air channel portion 20 and joint portion 30, and make connecting portion 40 and air channel portion 20 separate a certain distance, thus between connecting portion 40 and air channel portion 20, form an admission space 64.This admission space 64 is adjacent with tunnel inlet 211 and is connected with the inside in air channel 21 by tunnel inlet 211, and the size that admission space 64 is on the direction being parallel to central axis M is made the separate distance in air channel portion 20 and joint portion 30 determine by connecting portion 40.Connecting portion 40 makes joint portion 30 be suspended at the rear in air channel portion 20.Connecting portion 40 is by entity structure extension on the direction being parallel to central axis M, make joint portion 30 that connection portion 40 connects and air channel portion 20 separates so that joint portion 30 and tunnel inlet 211 pull open a certain distance, and then form an admission space 64 relatively opened wide at the rear of tunnel inlet 211.
In order to make tunnel inlet 211 obtain enough air quantity, connecting portion 40 is connected with air channel portion 20 composition in the outside of tunnel inlet 211.In the case of can guarantee that structural strength, connecting portion 40 can be only made up of an entity structure, the most only includes the top connecting portion 41 in Fig. 2, and remaining position is all not provided with entity structure.
Furthermore, in order to ensure the structural strength of whole hair-dryer 100 body, and making what hair-dryer 100 can consolidate to be placed on a table top, connecting portion 40 can also include base connecting portion 42.
For convenience of explanation, below with the side of top connecting portion 41 be upper, with the side of base connecting portion 42 be under.
Base connecting portion 42 is formed with one and supports end face (figure is not marked) in its bottom, and when supporting end face with deck contact, base connecting portion 42 can constitute effective support to hair-dryer 100.
Still further, in order to strengthen the bonding strength between joint portion 30 and air channel portion 20, connecting portion 40 also includes being arranged on the some middle rib 43 between top connecting portion 41 and base connecting portion 42, and they can also enter admission space 64 and hinder tunnel inlet 211 air intake by the bigger object of backstop in addition to increasing the effect of intensity.
In the case of ensureing structural strength, connecting portion 40 can be made up of one or several in top described above connecting portion 41, base connecting portion 42 and middle rib 43, the ingredient of all connecting portions 40 is all connected with air channel portion 20 composition when being connected to air channel portion 20 outside tunnel inlet 211, so be equivalent to them the admission space 64 at tunnel inlet 211 rear is constituted crowd around, spatially ensure that joint portion 30 and the separation in air channel portion 20, make the rear of tunnel inlet 211 have sufficiently large space and receive air-flow.
Additionally, connecting portion 40 not only acts as interconnection function between joint portion 30 and air channel portion 20, the entity structure of connecting portion 40 is at the Crack cause that the extension being roughly parallel to central axis M direction is admission space 64, the entity structure being simultaneously connected with portion 40 does not close admission space 64, specifically, the entity structure of connecting portion 40 makes admission space 64 be radially unlimited in the major part of central axis M.
It should be noted that, for central axis M, definition radially is the central shaft using central axis M as an imaginary circles cylinder, the radial direction of this imaginary circles cylinder be referred herein go out radial direction, and radial direction here the most singly refers to that some direction refers to the set that some directions form.The entity structure of connecting portion 40 is present in some circumferential position of this imaginary circles cylinder, in addition to some radial direction (set partially radially) corresponding with these circumferential positions, it is unlimited in remaining radial direction (another part set radially) upper air space 64.
In order to ensure air quantity, part occupied by the entity structure of connecting portion 40 should be much smaller that connecting portion 40 makes the part that admission space 64 opens wide, so as a whole, admission space 64 is radially unlimited at central axis M, during air-flow can be along the radial inflow of central axis M to admission space 64.
When connecting portion 40 is only made up of an entity structure, when being the most only made up of top connecting portion 41, what admission space 64 sentenced external central axis M except this entity structure place is unlimited the most everywhere.
When connecting portion 40 is made up of two different entity structures, such as when top connecting portion 41 and base connecting portion 42 or several middle ribs 43, it it is individuality independent of each other between them, the most now each entity structure of connecting portion 40 is discontinuous in the circumference of central axis M, then now admission space 64 except these constitute connecting portions 40 entity structure external central axis M be unlimited the most everywhere.
Preferably, the each occupied circumference arc of the entity structure independent in central axis M circumference of connecting portion 40 should be less than 30 degree, and the summation of the circumference arc that each entity structure of connecting portion 40 is occupied in central axis M circumference should be less than 90 degree, so ensure that admission space 64 unlimited part circumference arc in central axis M circumference more than or equal to 90 degree, and then can ensure that the intake of admission space 64.
Preferably, the housing 10 of hair-dryer 100 is also formed with the handle portion 50 gripped for user further.It is said that in general, handle portion 50 has a split S(as shown in Figure 2), the relative split S of this handle portion 50 is about symmetry, and admission space 64 could be arranged to be unlimited on the direction of vertical this split S.Because generally speaking, it is gripped by user from the top of handle portion 50, and handle portion 50 is symmetrical relative to split S, the direction being perpendicular to split S is left and right directions, and admission space 64 is unlimited to can guarantee that user grips the hands of handle portion 50 and will not affect very much the intake of admission space 64 at left and right directions.
Based on such purpose of design, as a kind of preferred version, by the same circumferential position of handle portion 50 with a part centrally disposed axis M of connecting portion 40 entity structure, handle portion 50 is positioned at the outside of the corresponding entity structure of connecting portion 40 for central axis M.
In order to ensure the structural strength of handle portion 50, handle portion 50 can not be too thin, therefore can be by corresponding with handle portion 50 for the entity structure of a part maximum for width dimensions in connecting portion 40 (i.e. the size of left and right directions or be perpendicular to the size in split S direction).The ratio outside of the top connecting portion 41 that handle portion 50 as shown in Figure 2 is formed in connecting portion 40, the circumferential position of they opposing axial M is corresponding.
It addition, preferably, as it is shown in figure 1, one end of handle portion 50 is connected to joint portion 30, when battery bag 63 is installed to joint portion 30, battery bag 63 and handle portion 50 lay respectively at the both sides up and down of joint portion 30.
For above-below direction, although top connecting portion 41 and base connecting portion 42 are respectively arranged at above and below admission space 64, but form the part of tunnel inlet 211 due to air channel portion 20 and joint portion 30 has one fixed width in the lateral direction, and their width is bigger than top connecting portion 41 and the actual width taken up space of base connecting portion 42 (although in Fig. 2, base connecting portion 42 is the most left has certain width to the rightest, but it is the frame structure of middle opening, in other words width shared by the entity structure of base connecting portion 42 little), so in the vertical direction, admission space 64 is also unlimited.
It is similar to, although in the middle of two, rib about 43 is arranged, but they only play the effect of connection, and they sizes occupied by reality in the vertical direction are the most extremely limited, and therefore admission space 64 is the most also unlimited.
In general, although admission space 64 is supported between air channel portion 20 and joint portion 30 by connecting portion 40 and makes they separation form, and actually the size of admission space 64 is to be determined by the size of the tunnel inlet 211 in air channel portion 20.First, connecting portion 40 each several part is connected in the outside of tunnel inlet 211 composition with air channel portion 20, it is simultaneously connected with portion 40 to be about extending along the direction being parallel to central axis M to realize connecting, so the size of tunnel inlet 211 determines admission space 64 in central axis M size radially.It addition, according to the demand of hair-dryer 100 air quantity, admission space 64 needs to ensure in the axial direction the wind needed for certain size, such guarantee air intake efficiency acquisition.
As a kind of preferred version, the length direction (referring to the direction of the two ends line of handle portion 50 ultimate range) of handle portion 50 is parallel to split S's, in other words conj.or perhaps be parallel to perpendicular, then admission space 64 be in the lateral direction unlimited can also be considered as admission space 64 be unlimited in the vertical direction of handle portion 50 length direction place plane.It should be noted that it is understood that the plane at the length direction place of handle portion 50 has multiple, and split S is only in multiple plane first.
It should be noted that " opening wide of admission space 64 a direction " described in this specification refers to that air-flow can enter in admission space 64 along a direction rather than fingering headroom 64 does not has any entity structure between the direction and the external world.Such as, in connecting portion 40, top connecting portion 41 and base connecting portion 42 lay respectively at the both sides up and down of central axis M, although being additionally provided with middle rib 43 between them, but owing to air-flow is can to enter into admission space 64 along the direction being perpendicular to perpendicular, so admission space 64 is pushing up between connecting portion 41 and base connecting portion 42 it is also assumed that be unlimited.For the opposing party, if connecting portion 40 is formed without the entity structure that the direction is completely covered by continuous print in one direction, if making air-flow can not need to walk around this entity structure along other directions along direction entrance admission space 64, it is unlimited for being considered as admission space 64 in the direction.
