As shown in fig. 1 to 3, the hair styling sealing member comprises an outer sleeve 100 and an inner sleeve 200, the inner sleeve 200 rotates inside the outer sleeve 100, a plurality of air outlets 110 are provided around the side wall of the outer sleeve 100, and the air outlets 110 are provided with a first opening 111 and a second opening 112 which are symmetrically arranged. Air outlets 110 are arranged at equal intervals around outer sleeve 100, and each air outlet 110 is provided with a first opening 111 and a second opening 112, and the air outlet directions of first opening 111 and second opening 112 are opposite. When the first opening 111 is blocked, wind is sprayed out from the second opening 112 to form clockwise air flow, and when the second opening 112 is blocked, wind is sprayed out from the first opening 111 to form anticlockwise air flow. The user switches the air flow direction according to the use requirement.

Specifically, the inner sleeve 200 comprises elastic sealing parts 300 arranged at the radial tail end of the inner sleeve 200, the elastic sealing parts 300 are circumferentially arranged at equal intervals on the outer ring of the inner sleeve 200, and the number of the elastic sealing parts 300 is equal to that of the air outlets 110. Inner sleeve 200 is coaxially disposed with outer sleeve 100, and when inner sleeve 200 rotates inside outer sleeve 100, inner sleeve 200 rotates and drives elastic sealing portion 300 to block first opening 111 or second opening 112 for changing the wind direction of air outlet 110. When the inner sleeve 200 rotates clockwise, the elastic sealing part 300 seals with the first opening 111, and the second opening 112 emits clockwise air flow, and when the inner sleeve 200 rotates counterclockwise, the elastic sealing part 300 seals with the second opening 112, and the first opening 111 emits counterclockwise air flow. The one set of elastic sealing parts 300 can seal only one set of the first opening 111 or the second opening 112 at a time, and each elastic sealing part 300 simultaneously seals the first opening 111 or the second opening 112.

The elastic sealing portion 300 includes a connecting seat 310 and sealing plates 320 disposed on two sides of the connecting seat 310, the surface of the connecting seat 310 is disposed in a gap with the inner wall of the outer sleeve 100, a guiding deformation groove 330 is disposed on a side, far away from the inner wall of the outer sleeve 100, of the connecting portion between the sealing plates 320 and the connecting seat 310, and the guiding deformation groove 330 is used for guiding the deformation direction of the sealing plates 320.

Specifically, when the sealing piece 320 at two sides of the elastic sealing portion 300 rotates to the limiting position in the inner sleeve 200, the sealing piece 320 is subjected to a tangential force, and at this time, the sealing piece 320 is deformed by force, so as to ensure that the sealing piece 320 can be deformed to fit the opening towards the outline of the opening, and the guiding deformation groove 330 provides a guiding effect in the deformation process of the sealing piece 320, so that the sealing piece 320 is deformed to fit in a preset direction. In cooperation with the operation of the hair styling apparatus, high-pressure air flow is output to the inside of outer sleeve 100, and the pressure in the air flow acts on sealing sheet 320, so that sealing sheet 320 continuously fits the opening and continuously seals. Innovation is achieved on the sealing mode of the opening, and a higher sealing effect is achieved by matching the pressure in the air flow and the external acting force.

And the gap between the top of connecting seat 310 and the inner wall of outer sleeve 100 is set, when inner sleeve 200 is rotating, the contact area between inner sleeve 200 and outer sleeve 100 is reduced, effectively reducing the rotation resistance. Compared with the existing inner and outer sleeve assembly, the hair styling sealing component in the embodiment has low assembly requirements on the inner and outer sleeve 100, and compared with the existing structure of tightly attaching two walls to seal the opening, the sealing effect of deformation sealing of the sealing piece 320 and continuous action and compaction of internal air pressure in the embodiment is better.

In some embodiments of the present utility model, as shown in fig. 2 and 3, sealing plate 320 extends along the top end surface of connection holder 310 toward both sides, and the tip end of sealing plate 320 is in contact with the inner wall of outer sleeve 100. Specifically, the surface of sealing plate 320 is parallel to the top end surface of connecting seat 310, while the end of sealing plate 320 contacts the inner wall of outer sleeve 100, and the rest is spaced from the inner wall of outer sleeve 100, so that the contact area is reduced, only sealing plate 320 is partially contacted between inner sleeve 200 and outer sleeve 100, the rotation resistance is effectively reduced, and the adjusting feel is better.

In a further embodiment, as shown in fig. 2 and 3, the ends of the sealing plate 320 are arranged in a circular arc. Specifically, the distal ends of sealing pieces 320 are smooth, and the contact friction between sealing pieces 320 and the inner wall of outer sleeve 100 can be reduced when inner sleeve 200 rotates. And in the process of deforming the sealing piece 320 to seal the opening, the end arc structure can also play a role in guiding deformation, and the sealing piece 320 is easier to fit the outline of the opening under the combined guiding effect of the guiding deformation groove 330 and the end arc structure.

The top of connecting seat 310 is prevented from being raised by the pressing external force to contact with the inner wall of outer sleeve 100 during the deformation of elastic sealing portion 300, resulting in increased resistance.

In some embodiments of the present utility model, as shown in fig. 3, the ratio of the groove depth of the guide deformation groove 330 to the thickness of the sealing sheet 320 is 0.2 to 0.5. Specifically, the specific groove depth of the guide deformation groove 330 is adjusted according to the material strength of the sealing sheet 320.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the inner sleeve 200 is provided with a connection shaft 210 and a support base 220 radially disposed along the connection shaft 210, the number of the support bases 220 is equal to that of the air outlets 110, and the support bases 220 are connected with the connection base 310. Specifically, the supporting seats 220 are radially distributed about the connecting shaft 210.

Specifically, when the inner sleeve 200 drives the elastic sealing portion 300 to rotate and the sealing piece 320 touches the limiting portion 120, the sealing piece 320 deforms to block the opening under the action of external force.

The hair styling apparatus comprises the hair styling sealing member, a driving part and an adjusting part. A driving part is coupled to outer sleeve 100, an adjusting part is coupled to inner sleeve 200, and the adjusting part is used to rotate inner sleeve 200 so that elastic sealing part 300 seals first opening 111 or second opening 112.
