Specific embodiment

With reference to Fig. 1,2A and 2B, the embodiment of hand-held instruments is shown.The utensil has handle 210 and for head of being formed The attachment 20 of hair.In order to enable user can create different shaping and and provide multiple functions for utensil, attachment 20 is removable And it can be replaced by substitution attachment.In addition, attachment 20 can be removed to allow for the more easily storage of utensil when not in use.Handle 210 include UI (user interface) 230 comprising by several different user operation buttons 38,138, allow users to it is several not It is selected between heating and flowing setting.Handle 210 includes fan unit 70 and heater 80.Fan unit 70 has motor 76 With fan 78, when motor is activated, fan rotates.In use, 70 draw fluid of fan unit passes through fluid inlet 212, edge Fluid flow path 100 is advanced, and is passed through heater 80, is selectively heated fluid, and then the fluid passes through in attachment 20 Fluid outlet 22 emits.

Handle 210 has outer wall 200 and an inner wall 220, the outer wall 200 along longitudinal direction axis X-X from fluid inlet 212 towards hand The fluid outlet 202 of handle 210 extends, which accommodates fan unit 70 and heater 80.

Enter the fluid of fluid flow path 100 to the filtering of fluid inlet 212 of handle 210.The outer wall 200 provided Filter grid grid 204, inner wall 220 provide filter screen 224.Filter screen 224 is narrower than filtering grid 204 and is suitable for capturing dust and suede Hair.Filtering grid 204 is removable filter screen 224 regularly to be cleaned.

Once fluid has entered utensil, it is guided through PCB 120.The inner wall 220, which advantageously provides, to be used for The shell 222 of PCB120, the shell limit the position of PCB 120.Due to the electrical part with different sizes and shapes of PCB 120 Part is installed in above it, so that PCB 120 is accommodated in shell 222, reduces the turbulent flow in utensil 10, noise and pressure Loss.At the downstream end 120b of PCB, inner wall 220 is bent around the end of PCB 120 towards fan unit 70.The downstream The shape of end is designed to reduce the flow separation from the outer surface 222a of shell 222.

Between PCB 120 and fan unit 70, grid 60 is set.As usual, this grid hole having the same Array, usually hexagon and can be decided to be as entry grates, export a part in grid or utensil, and reduce and enter The turbulent flow of utensil, fan unit or ejection tool.In order to adapt to the transverse movement of fan unit 70, the fan unit 70 of grid 60 Including widened hole 60, size is set to be allowed for the axis 74 of fan unit 70 to pass through grid 60.Remaining hole 64 is substantially Hexagon is to maximize the opened areas of grid 60.Grid 60 is arranged to homogenize fluid flowing before fan unit 70, And its use reduces the noise generated in utensil.

Referring now to Fig. 3-6, grid 60 will be described in more detail.Grid 60 has external frame 160 and a series of interior Portion's wall 162 (it limits both centre bore 62 and remaining hole 64).The radially inner side portion 160a of frame 160 limits the opening of grid 60 Region, and the cross section of fan 78 is matched, and the register with fan unit 70.The stream being discharged as a result, from grid 60 Body has the straight path to fan unit 70.

Grid 60 has the first side 66 and the second side 68, and interior wall 162 asymmetrically passes through grid 60.For grid 60 are correctly positioned, that is, the first side 66, adjacent to fan unit 70, positioning convex point 164 is set, and are arranged on Recess (not shown) engagement in inner wall 220.Interior wall 162 be it is asymmetric, rise have tapered profiles to help to manufacture (the portion Point discharged from the mold of mold tool) and the sound transmitting of grid is minimized, and at the second side 68, the side of interior wall 162 Edge 162a is rounding to guide fluid to enter grid 60, to be further reduced sound by mitigating the turbulent flow as caused by grid Transmitting.

Gap 166 is present between the downstream end 120b of shell 222 and grid 60, and this gap 166 be set with The mixing for the fluid for allowing to flow on the either side of PCB 120.There is speed between the fluid flowed on the two sides of PCB120 Mismatch is spent, and these fluids is allowed to go to mixed space that can reduce mismatch, then the further Uniform Flow of grid 60 and reducing always Speed.

Although the present invention has referred to the description of heat-shaping equipment, rotary connector can be used in any hand-held instruments Interior, wherein utensil includes about the relative rotation of user, but is not limited to straightener and curly hair equipment (such as fixture, stick Or ironing).In these embodiments, when fluid stream is not used at type-approval process, handle 210 will not include fan unit but Including heater or it will be heated surface, and pass through its shaping hair.
