The body 10 is capable of driving air into the intake 102 to form a fluid within the fluid passageway 100, which is capable of moving through the fluid passageway 100 towards the outlet 101 and out of the outlet 101 to act on hair.

To sum up, implement the embodiment of the utility model provides a, will have following beneficial effect: the accessory 20 of the scheme is applied to the hair care equipment, and has the noise reduction effect besides enabling the hair care equipment to have excellent shaping care efficiency, so that noise generated when the hair care equipment generates air flow can be reduced, and the use experience of a user is improved. Specifically, the attachment 20 includes a silencer 21 disposed near the outlet 101, and a silencer chamber 200 is disposed in the silencer 21. The muffler member 21 is provided with a plurality of first through holes 300 communicating the fluid passage 100 with the muffler chamber 200. Thus, the sound-absorbing member 21 forms a sound-absorbing element with high sound resistance and low sound quality, so that the sound energy of the noise with the same frequency as the sound-absorbing cavity 200 can be consumed to reduce the noise.

In one embodiment, the muffler member 21 includes a circumferential wall 211 located in a radial direction of the fluid passage 100, and the first through-hole 300 is formed in the circumferential wall 211. As shown in fig. 3 and 4, the fluid channel 100 is disposed around the circumferential wall 211, that is, the sound-deadening chamber 200, the circumferential wall 211 and the fluid channel 100 are disposed in the radial direction of the fluid channel 100 from the inside to the outside, and the circumferential wall 211 is disposed around the sound-deadening chamber 200.

Specifically, as shown in fig. 3 and 4, the fluid passage 100 is circumferentially provided to the circumferential wall 211, and the axial directions of any two first through holes 300 are staggered. Thus, the noise sound wave can be prevented from being directly discharged from other first through holes 300 coaxial with the first through hole 300 by being propagated into the silencing cavity 200 along the axial direction of one first through hole 300, and the noise reduction effect is avoided. Specifically, the axial directions of any two first through holes 300 are staggered, so that when a noise sound wave propagates into the sound deadening chamber 200 along the axial direction of one first through hole 300, the noise sound wave can be completely or partially propagated to the circumferential wall 211 to rebound the noise sound wave and generate resonance, so as to reduce noise. In the present embodiment, the axial direction of the first through hole 300 is coaxial with the radial direction of the circumferential wall 211. It is understood that in other embodiments, the axial direction of the first through hole 300 may also be staggered from the radial direction of the circumferential wall 211.

In one embodiment, referring to fig. 3-5 and 7, the fluid channel 100 is disposed around the circumferential wall 211. The muffler member 21 further includes a first soundproof portion 212. First sound insulating portion 212 is housed in sound-deadening chamber 200, and an orthographic projection of at least a part of first through hole 300 in the axial direction thereof is located on first sound insulating portion 212. The same arrangement of first sound insulating portion 212 can be used to prevent noise reduction effect from being lost by noise sound waves propagating into muffler chamber 200 in the axial direction of one of first through holes 300 and directly being discharged from another first through hole 300 coaxial with first through hole 300. In the present embodiment, the first sound insulating portion 212 extends in the axial direction of the circumferential wall 211. The plurality of first through holes 300 can form a first porous region and a second porous region on the circumferential wall 211. The first porous area and the second porous area are adjacent to each other and are disposed near the air outlet 101, the first sound insulation portion 212 is accommodated in a space surrounded by the first porous area, and an orthographic projection of the first through hole 300 located in the first porous area along the axial direction thereof is located on the first sound insulation portion 212. In this embodiment, any two first through holes 300 of the plurality of first through holes 300 located on the circumferential wall 211 are staggered in the axial direction or at least one set of two coaxially arranged first through holes 300 exist in the plurality of first through holes 300. In another embodiment, the first sound insulation part 212 can be inserted into the space enclosed by the whole circumferential wall 211, and at least one set of two coaxially arranged first through holes 300 exist in the plurality of first through holes 300 or in the axially staggered space of any two first through holes 300 in the plurality of first through holes 300 on the circumferential wall 211.

In one embodiment, referring to fig. 1, fig. 3, fig. 4 and fig. 7, the sound attenuating element 21 further includes a cover plate 213. The cover plate 213 covers the circumferential wall 211 near the outlet 101, the circumferential wall 211 is made of metal, and the cover plate 213 is made of heat insulating material. In this embodiment, the fluid channel 100 further accommodates a heating unit 30 therein to heat the fluid flowing through the heating unit 30. The circumferential wall 211 is made of metal materials, so that the rigidity of the circumferential wall 211 can be improved, the circumferential wall 211 is prevented from being deformed due to compression in the assembling and using processes, and the circumferential wall 211 is prevented from being heated to deform greatly when the radiant heat of fluid is too high, so that the noise reduction effect is prevented from being influenced. And cover plate 213 is located on the outside of the hair care device as a whole and is easily in contact with the body during and immediately after use of the hair care device. Therefore, the cover plate 213 is made of a heat insulating material, and can prevent the body from being scalded. Further, in the present embodiment, the first sound insulating portion 212 is provided in the cover plate 213. The first noise insulation portion 212 has a plate-like structure. As shown in fig. 3 and 6, the circumferential wall 211 is provided with an insertion groove 400 to be inserted into the first soundproof portion 212. The connection between the cover plate 213 and the circumferential wall 211 and/or between the first acoustic insulation 212 and the circumferential wall 211 can also be by means of gluing.

In one embodiment, referring to fig. 3 and 7, the muffler 21 further includes an end plate 214. The end plate 214 covers the side of the circumferential wall 211 far away from the air outlet 101 and can enclose to form a cavity 500, and the silencing cavity 200 is communicated with the cavity 500. So can extend noise damping chamber 200 through setting up of cavity 500, increase its non-first through-hole 300 and enclose and establish the region, so can effectively control the position that noise damping chamber 200 resonates and absorbs the peak, and then promote noise reduction effect. Further, the end plate 214 is detachably connected to the body 10 via the connecting member 40 to facilitate replacement and maintenance of the attachment 20. In particular, the connection 40 is a screw. The side of the end plate 214 facing away from the sound-deadening chamber 200 is provided with a projection 22. The protrusion 22 is provided with a threaded opening for engaging the connecting member 40.

In one embodiment, the first through-hole 300 has a hole diameter of 0.2mm to 6 mm. Since the acoustic resistance is inversely proportional to the aperture of the first through hole 300, designing the aperture of the first through hole 300 to be a small size can increase the acoustic resistance, thereby improving the sound absorption coefficient of the silencer 21. Further, the perforation rate of the first through-holes 300 on the circumferential wall 211 is 1% to 30%. The perforation rate refers to the ratio of the sum of the areas of all the first through holes 300 to the area of the circumferential wall 211. The acoustic quality of the structure can be reduced due to the low perforation rate. Because the sound absorption bandwidth is the ratio of acoustic resistance to acoustic mass, consequently, the aperture of first through-hole 300 designs into less size, and the perforation rate of first through-hole 300 on circumferential wall 211 designs into lower sound absorption bandwidth that can make amortization piece 21 and obtains widening, further promotes the noise reduction effect.

In one embodiment, sound-absorbing material is housed within sound-deadening chamber 200. Therefore, the frequency range of effective noise elimination can be widened by arranging the sound absorption material, and the noise reduction effect is further improved. In this embodiment, the sound absorbing material may be sound absorbing cotton, but is not limited thereto.

In one embodiment, the accessory further comprises at least one annular wall. The annular wall is accommodated in the silencing cavity and is arranged at intervals with the circumferential wall so as to be capable of surrounding the silencing piece to divide the silencing cavity into a plurality of cavities, and a plurality of second through holes are formed in the annular wall so as to communicate the adjacent cavities. So can form the chamber that a plurality of porous structure enclose through the setting of cyclic annular wall by the amortization piece, form a plurality of amortization chamber units promptly to can carry out noise reduction to the noise jointly. Each chamber and the first and/or second through-holes communicating therewith can form a plurality of resonant systems. Each resonance system can eliminate noise sound waves of the same frequency and can also eliminate noise sound waves of different frequencies. In order to make it possible for the respective resonant system to cancel noise sound waves of different frequencies, the accessory can be designed at least in the following way:

the first through hole and the second through hole have different apertures; and/or

The perforation rate of the first through holes on the circumferential wall is different from the perforation rate of the second through holes on the annular wall; and/or

The second through holes on different annular walls have different perforation rates.

In one embodiment, the fluid passage is provided around the circumferential wall, and the orthographic projection of the first through holes on the annular wall adjacent to the circumferential wall along the axial direction of the first through holes is staggered with the second through holes on the annular wall. Therefore, the noise sound wave can be prevented from being propagated to a cavity adjacent to the circumferential wall along the axial direction of one first through hole and directly discharged from the second through hole on the annular wall coaxial with the first through hole, and the noise reduction effect is avoided. The design enables the noise sound wave to be completely or partially transmitted to the annular wall adjacent to the circumferential wall when the noise sound wave is transmitted to the cavity along the axial direction of one first through hole, so that the noise sound wave is rebounded to generate resonance, and the noise is reduced. Further, the second through holes on the outer annular wall of the adjacent annular walls are staggered with the second through holes on the inner annular wall along the orthographic projection of the second through holes on the inner annular wall of the adjacent annular walls in the axial direction. Therefore, the noise sound wave can be prevented from being propagated into the cavity between the adjacent annular walls along the axial direction of one second through hole on the annular wall positioned on the outer side in the adjacent annular walls and directly discharged from the second through hole on the annular wall positioned on the inner side and coaxial with the second through hole, and the noise reduction effect is avoided. The design enables the noise sound wave to be completely or partially transmitted to the inner annular wall to rebound the noise sound wave when the noise sound wave is transmitted to the chamber along the axial direction of one second through hole on the outer annular wall, and resonance is generated so as to reduce the noise.

Further, the fluid channel is arranged on the circumferential wall in a surrounding mode, and any two second through holes in the annular wall located on the innermost side of the silencing cavity are staggered in the axial direction. Therefore, noise sound waves can be prevented from being propagated into a cavity surrounded by one second through hole along the axial direction of one second through hole on the annular wall at the innermost side of the silencing cavity and being directly discharged from the other second through hole coaxial with the second through hole, and the noise reduction effect is avoided. Specifically, the axial direction of any two second through holes on the annular wall at the innermost side of the sound-deadening cavity is staggered, so that when the noise sound wave is transmitted to the sound-deadening cavity along the axial direction of one second through hole on the annular wall at the innermost side of the sound-deadening cavity, the noise sound wave can be completely or partially transmitted to the annular wall to rebound and generate resonance, and noise is reduced.

In this embodiment, at least one set of two coaxially disposed second through holes exists in the plurality of second through holes located on the annular wall at the innermost side of the sound-deadening chamber or in the plurality of second through holes located on the annular wall at the innermost side of the sound-deadening chamber.

In one embodiment, the circumferential wall surrounds the fluid passage. The orthographic projection of the first through holes on the annular wall adjacent to the circumferential wall along the axial direction of the first through holes is staggered with the second through holes on the annular wall. Therefore, the noise sound wave can be prevented from being propagated to a cavity adjacent to the circumferential wall along the axial direction of one first through hole and directly discharged from the second through hole on the annular wall coaxial with the first through hole, and the noise reduction effect is avoided. The design enables the noise sound wave to be completely or partially transmitted to the annular wall adjacent to the circumferential wall when the noise sound wave is transmitted to the cavity along the axial direction of one first through hole, so that the noise sound wave is rebounded to generate resonance, and the noise is reduced. Furthermore, the orthogonal projection of the second through hole on the inner annular wall of the adjacent annular walls on the outer annular wall of the adjacent annular walls along the axial direction of the second through hole is staggered with the second through hole on the outer annular wall. Therefore, the noise sound wave can be prevented from being propagated into the cavity between the adjacent annular walls along the axial direction of one second through hole on the annular wall positioned on the inner side in the adjacent annular walls and directly discharged from the second through hole on the annular wall positioned on the outer side and coaxial with the second through hole, and the noise reduction effect is avoided. The design enables the noise sound wave to be completely or partially transmitted to the annular wall on the outer side to rebound the noise sound wave when the noise sound wave is transmitted to the chamber along the axial direction of one second through hole on the annular wall on the inner side, and resonance is generated so as to reduce the noise.
