Abstract

A diffuser is used for a hand-held electric air blower. The diffuser comprises a base. Finger-shaped elements extend from the base. Each finger-shaped element comprises a longitudinal passage. Hot air coming from the base passes through the longitudinal passage. A heat capacity element is connected with the base. The heat capacity element is used for adjusting the temperature change of air discharged from the diffuser.

Description

The hair-dryer diffuser

Technical field

The present invention relates to the diffuser (diffusers) of hair-dryer, more particularly,, the present invention relates to a kind of air diffuser that together uses with electronic hair-dryer with warm keeping element though do not get rid of other diffuser.

Background technology

For the heat of hand electric hair-dryer air-supply ozzle provides diffuser is well-known.Design these areas that are used for making thermal current diffuse to hair and compare, can provide a kind of gentleness like this and a large-area effect of doing there not being the area that thermal current spreads under the situation of diffuser big.This kind of great majority diffuser is limited on the significant degree of diffusion air-flow.For example, some this kind diffusers provide a flat substrate, obtain diffusion through this area of base by many apertures, and many fingers that penetrate hair extend from this substrate.The air that has passed through aperture plate is used for slowing down around finger, and still, because in use hair has covered these fingers, thereby in fact hair has blocked flow channel.

Another problem relevant with known air diffuser is possible can't provide the means of stablizing the diffusion gas temperature.Therefore, activate and inactive state during a period of time when hair-dryer is in, temperature may clearly fluctuate up and down.

Summary of the invention

The objective of the invention is to overcome or improve at least one of above-mentioned deficiency fully and/or more generally provide improved hot air diffuser for the hand electric hair-dryer.

This paper provides the diffuser that is used for the hand electric hair-dryer, comprise a substrate, a plurality of fingers extend out with interior annular array and the outer ring-like array with common center from substrate, and each finger all comprises a vertical passage, and the hot-air that comes from substrate therefrom passes through; Wind pushing hole, along the basad longitudinal extension of inward flange, wherein each wind pushing hole all links to each other with substrate towards described common center and thermal capacitance element this wind pushing hole from the end of each finger, is used for modulating the variations in temperature of the air of discharging by diffuser.

Preferably is, diffuser comprises that further first air inlet that is connected with array in the finger and one are around first air inlet and ring-type second air inlet that is connected with the outer array of finger.

Preferably is that diffuser has one or more apertures so that hot-air can flow through this place.

Preferably is that finger is around the thermal capacitance element.

Preferably is, a kind of material of selecting in the combination that this element is made up of pottery, metal and glass constitutes.

Diffuser is can be with the hair-dryer main body integrally formed or form as the auxiliary equipment of hair-dryer main body.

Description of drawings

Now preferred form of the present invention is described with reference to the accompanying drawings in the mode of example as follows, wherein:

Fig. 1 is the perspective illustration of diffuser,

Fig. 2 is the schematic front view of diffuser among Fig. 1,

Fig. 3 be the intercepting Fig. 2 III-III to the part schematic sectional view,

Fig. 4 is the schematic sectional view among similar Fig. 3, provided passage that air flows through and

Fig. 5 is the schematic sectional view among similar Fig. 4 of an alternate embodiments.

The specific embodiment

In the accompanying drawings, schematic depiction diffuser 10, it typically is made of molded plastic material, and comprises a flange 11, can be connected with the air-supply ozzle of hand electric hair-dryer (not shown) by this flange diffuser.

This diffuser comprises a substrate 12, extends a plurality of fingers 13 by this substrate.Each finger all has long wind pushing hole 14, and wind pushing hole 14 extends from terminal 15 along inner edges.Finger 13 can constitute with substrate 12 integral body, perhaps forms as a separated portions, is fixed in the substrate 12 at tie point 16 places by screw 23.

Finger 13 is made up of the array of two concentric ring-types, comprises an interior array 17 and an outer array 18.

Be one first or center air intake passage 19 in flange 11 inside, arrive the interior array 17 of finger from the hot-air of hair-dryer via this passage.This air intake passage by a circular passage around, arrive the outer array 18 of finger via this circular passage from the hot-air of hair-dryer.The passage of each air-flow is seen attached Figure 4 and 5.

There are a thermal capacitance element or thermal capacitance element 21 in central authorities in array of fingers, and thermal capacitance element 21 is fixed in the substrate 12.The shape of this element can be a concavity as shown in Figure 4, or flat-shaped as shown in Figure 5.This thermal capacitance element can by pottery, metal, glass or other protect that hot materials make, and comprise that a plurality of holes 22-some of them are the groove that is radial extension, some otherly be the circle shape.Some air of central air intake passage 19 of flowing through can pass the thermal capacitance element, rather than move on and pass array in the finger.

In use, diffuser is connected to air-supply ozzle with the hand electric hair-dryer and forms all whole parts and link together.When hot-air when crossing and run through by the thermal capacitance element, can obtain and preserve heat.If hair-dryer temporarily stops, this heat can be preserved until hair-dryer and be activated again, at this moment the heat transferred that will locate through via hole or be right after the air-flow that route under it flow to array within the finger.When diffuser process hair, air-flow moves on along long wind pushing hole 14 and blows hair so that hair becomes dry.

Should be appreciated that conspicuous modification or replacement should not think to have exceeded scope of the present invention for those skilled in the art.For example, an independent air inlet can all be connected with the inside and outside array and the warm keeping element of finger, and substituting provides a central air intake passage and around its passage that the angle is arranged.
