Referring to fig. 4, 5 and 7, the first adjusting member 21 includes a cover. Specifically, in this embodiment, the cover body is an end cover with a substantially arc-shaped cross section, and a semi-ellipsoidal groove is formed in a middle region of one side of the cover body close to the second adjusting member 22.

In other embodiments, the recess may be hemispherical or other shapes.

In other embodiments, the cover may be a planar end cap or other type of cover.

As shown in fig. 4 and 5, the first ventilation slot 211 includes a plurality of first air outlets arranged along the circumferential direction of the cover body at intervals, and the first air outlets penetrate through two ends of the cover body. In this embodiment, the first air outlets are uniformly spaced around the groove of the cover, so that the air flow blown out by the blower 100 through the first ventilation slot 211 is uniform annular air flow.

The shape of the first air outlet hole comprises at least one of a rectangle, a triangle, a circle, an ellipse or an arc. In this embodiment, the first air outlet holes are all rectangular air outlet holes. It can be understood that the opening of the first air outlet near the end of the second adjusting member 22 is the air inlet of the first ventilating slot 211.

In this embodiment, the axis of the first air outlet is parallel to the axis of the hair dryer body 10, so that the air flow blown out through the first ventilation slot 211 is an annular air flow parallel to the axial direction of the hair dryer body 10. Obviously, in other embodiments, the axis of the first air outlet may not be parallel to the axis of the hair dryer body 10, and the axis of the first air outlet gradually moves away from the axis of the hair dryer body 10 along the airflow direction, so that the airflow blown out through the first ventilation slot 211 is an annular airflow spreading outward.

As shown in fig. 4 and 7, the second ventilating slot 212 includes at least one second ventilating hole, at least one groove or at least one spiral groove disposed in the middle area of the cover.

Preferably, in this embodiment, the second ventilating slot 212 includes a strip-shaped slot, the strip-shaped slot extends along the radial direction of the cover body, and penetrates from one end of the cover body far away from the second adjusting member 22 to the groove of the cover body, and the air flow blown out by the blower 100 through the second ventilating slot 212 is a narrowed strip-shaped air flow.

In other embodiments, the second ventilating slot 212 may include a plurality of strip-shaped slots, each of the strip-shaped slots extends along the radial direction of the cover body and penetrates from one end of the cover body far away from the second adjusting member 22 to the groove of the cover body, and the plurality of strip-shaped slots may be distributed divergently about the center of the cover body or distributed in parallel and at intervals along the radial direction of the cover body.

In other embodiments, the second air vent groove 212 may include at least one spiral groove disposed in the middle region of the cover, and the blower blows air through the spiral groove, so that the area of the blower blowing air through the middle region of the cover is increased, the speed of blowing air is reduced, but the blowing air is uniform, and the blower can be used in the occasions where the blowing air is uniform and the speed of blowing air is low.

Further, in this embodiment, the cover body is provided with at least one notch 213 along the circumferential direction, and the notch 213 is located between two adjacent first air outlets. Specifically, in this embodiment, a gap 213 is disposed between every two adjacent first air outlets. Each of the notches 213 is communicated with the groove in the middle area of the cover, and the notches 213 are communicated with the second ventilating grooves 212.

It should be noted that, in this embodiment, the cover body is provided with a hemispherical groove, which not only can reduce the weight of the first adjusting member 21, but also can reduce the wind resistance by comparing the spherical surface of the groove with a plane, so that a certain flow guiding effect is provided, which is more beneficial for the air flow generated by the blower 100 to be blown out through the second air duct 212. Obviously, in other embodiments, the cover may not be provided with a groove.

Referring to fig. 4 and 5, the second adjustment member 22 includes an annular base 223. In this embodiment, the wind shielding structure 221 includes a plurality of wind shielding sheets disposed on the inner wall of the annular base 223 at intervals along the circumferential direction of the annular base 223, the plurality of wind shielding sheets correspond to the plurality of first wind outlets disposed at intervals, and the number of the wind shielding sheets is the same as the number of the first wind outlets.

In other embodiments, the wind shielding structure 221 includes a wind shielding ring continuously disposed on the inner wall of the annular base 223 along the circumferential direction of the annular base 223 and having a plurality of third wind outlet holes at intervals along the circumferential direction, similarly, the plurality of third wind outlet holes are uniformly spaced from the plurality of first wind outlet holes, and the number of the third wind outlet holes is the same as the number of the first wind outlet holes. When the third air outlet is correspondingly communicated with at least one of the first air outlet and the notch 213, the air flow generated by the blower 100 is blown out through the third air outlet and the first air outlet and/or the notch 213 communicated with the third air outlet.

Further, referring to fig. 3, fig. 6 and fig. 7, in the present embodiment, the adjusting assembly 20 further includes a blocking piece 23 fixedly connected to the wind shielding structure 221 (i.e., a plurality of wind shielding sheets), and the blocking piece 23 is disposed corresponding to a middle area (i.e., a groove) of the cover body to block the remaining portion of the second air vent groove 212 except for the air inlet.

Specifically, as shown in fig. 3, one end of the blocking piece 23 close to the first adjusting piece 21 is fixedly connected to one end of each of the wind-blocking pieces far away from the annular base 223, and an end surface of one end of the blocking piece 23 close to the first adjusting piece 21 is flush with a surface of one side of each of the wind-blocking pieces close to the first adjusting piece 21. As shown in fig. 6 and 7, when the first adjusting member 21 and the second adjusting member 22 are assembled together, the blocking member 23 blocks a middle region of the first adjusting member 21 (i.e., a groove portion of the cover), and at least one of the first air outlets and the notches 213, which are circumferentially spaced on the first adjusting member 21, may leak out through a gap between two adjacent wind-blocking sheets on the second adjusting member 22, so as to facilitate the air flow.

As mentioned above, the opening of the first air outlet near the end of the second adjusting member 22 is the air inlet of the first ventilating slot 211; the notch 213 is communicated with the groove of the cover body, and further communicated with the second ventilation groove 212, when the blocking piece 23 shields the groove, the notch 213 also forms an air inlet of the second ventilation groove 212.

The plugging member 23 may be a plane structure, or a cone, a hemisphere or a bullet structure. Preferably, in this embodiment, the blocking piece 23 is a shell blocking piece with a bullet structure, which not only has a light weight, but also can form a ventilation channel between the blocking piece 23 and the blower body 10, which gradually narrows along the airflow direction, and is beneficial to increase the speed of the airflow.

It can be understood that when the first adjusting member 21 and the second adjusting member 22 rotate relatively, the wind shielding structure 221 (i.e., the plurality of wind shielding plates) rotates circumferentially relative to the first wind outlet and the gap 213, so that the wind shielding structure 221 can shield the wind inlet of the first ventilating slot 211 or the wind inlet of the second ventilating slot 212.

Specifically, referring to fig. 4 and 5, in this embodiment, a circle of the first connecting ring 15 is protruded from the air outlet of the hair dryer body 10 along the axial direction, a circle of the first receiving groove 225 is correspondingly formed at one end of the inner wall of the annular base 223 close to the hair dryer body 10, the outer diameter of the first connecting ring 15 is slightly larger than the diameter of the first receiving groove 225, the second adjusting element 22 is fixedly connected to the air outlet of the hair dryer body 10 by a snap-fit manner, the first connecting ring 15 is received in the first receiving groove 225, and the second adjusting element 22 is fixed relative to the hair dryer body 10.

In other embodiments, the outer circumferential surface of the first connecting ring 15 and the inner circumferential surface of the first receiving groove 225 may be provided with corresponding external threads and internal threads, and the second adjusting member 22 is fixed at the air outlet of the hair dryer body 10 by a threaded connection.

Wherein, the blocking piece 23 fixedly connected with the wind shielding structure 221 is partially accommodated in the inner cavity of the hair drier body 10.

As shown in fig. 4, 5 and 7, in this embodiment, a second connecting ring 227 is axially and convexly disposed on an end surface of the annular base 223 near one end of the first adjusting member 21, a circle of second receiving grooves 214 is correspondingly circumferentially disposed on the end surface of the first adjusting member 21 near one end of the second adjusting member 22, and the second connecting ring 227 can be inserted into the second receiving grooves 214 to rotatably connect the first adjusting member 21 and the second adjusting member 22. In this embodiment, the second adjusting part 22 is fixedly connected to the hair dryer body 10, and when the user rotates the first adjusting part 21, the wind shielding structure 221 can rotate circumferentially relative to the first wind outlet and the gap 213, so as to shield the wind inlet of the first ventilating slot 211 or the wind inlet of the second ventilating slot 212.

In other embodiments, the first adjusting part 21 may be fixedly connected to the air outlet of the hair dryer body 10, the second adjusting part 22 is rotatably connected to the first adjusting part 21, and the wind shielding structure 221 may also shield the air inlet of the first ventilating slot 211 or the air inlet of the second ventilating slot 212 by rotating the second adjusting part 22, which is not described herein again.

More specifically, as shown in fig. 6, in the present embodiment, after the first adjusting member 21 and the second adjusting member 22 are assembled together, the blocking member 23 shields a middle area of the first adjusting member 21, and the air inlet of the first ventilating groove 211 and the air inlet of the second ventilating groove 212 (i.e., the notch 213) leak through a gap between two adjacent wind shielding sheets and are distributed in a staggered manner along the circumferential direction of the first adjusting member 21.

When the second adjusting member 22 rotates relative to the first adjusting member 21 along the first direction a, that is, the wind shielding structure 221 (i.e., the plurality of wind shielding plates) rotates relative to the first wind outlet hole and the gap 213 along the first direction a, the wind shielding structure 221 can shield the wind inlet of the first ventilating slot 211; when the second adjusting member 22 rotates relative to the first adjusting member 21 along the second direction B, that is, when the wind shielding structure 221 rotates relative to the first wind outlet and the gap 213 along the first direction B, the wind shielding structure 221 may shield the wind inlet (i.e., the gap 213) of the second wind trough 212.

Wherein the first direction A is opposite to the second direction B. In this embodiment, the first direction a is a clockwise direction shown in fig. 6, and the first direction B is a counterclockwise direction shown in fig. 6.

It should be noted that, in this embodiment, an interval between the adjacent first air outlet and the gap 213 in the circumferential direction is smaller, and the wind-shielding sheet is slightly larger than the first air outlet and the gap 213, so that when the wind-shielding structure 221 rotates at different angles in the circumferential direction, the wind-shielding sheet may only shield the first air outlet, or only shield the gap 213, or simultaneously shield a part of the first air outlet and a part of the gap 213. Preferably, in this embodiment, the first adjusting part 21 and the second adjusting part 22 may be correspondingly provided with scale bars for indicating a rotation angle, so as to remind a user of the rotation angle of the wind shielding structure 221 along the circumferential direction, and further clarify the condition that the wind shielding sheet shields the first air outlet and the gap 213, for example, the first adjusting part 21 is provided with a first scale bar, the second adjusting part 22 is provided with a second scale bar and a third scale bar, and when the first scale bar and the second scale bar are aligned or approximately aligned, it is described that the first air outlet is shielded by the wind shielding sheet; when the first scale bar and the third scale bar are aligned or approximately aligned, the windshield covers the notch 213; when the first scale bar is located between the second scale bar and the third scale bar, it is stated that the wind-guard sheet simultaneously shields a part of the first wind-outlet and a part of the gap 213.

In other embodiments, the second adjusting member 22 can rotate continuously along the first direction a or rotate continuously along the second direction B relative to the first adjusting member 21, that is, when the wind shielding structure 221 (a plurality of wind shielding sheets) rotates continuously along the first direction a or rotates continuously along the second direction B relative to the first wind outlet and the gap 213, the wind shielding structure 221 alternately shields the wind inlet of the first ventilating slot 211 and the wind inlet of the second ventilating slot 212.

Referring to fig. 6 to 11, as mentioned above, in the present embodiment, in the process that the second adjusting part 22 rotates relative to the first adjusting part 21 along the circumferential direction, the shielding of the wind shielding structure 221 to the first wind outlet (i.e., the wind inlet of the first ventilating slot 211) and the gap 213 (i.e., the wind inlet of the second ventilating slot 212) may be different.

Specifically, as shown in fig. 6 and 7, when the wind shielding structure 221 does not shield the wind inlets of the first ventilating slot 211 and the second ventilating slot 212, the blower 100 blows wind through the first ventilating slot 211 and the second ventilating slot 212, and at this time, the blower 100 is in the first wind blowing mode, and the wind blown by the blower 100 includes a uniform annular airflow blown out through the first ventilating slot 211 and a narrowed strip-shaped airflow blown out through the second ventilating slot 212; as shown in fig. 8 and 9, when the wind shielding structure 221 shields the wind inlet of the second ventilating slot 212, the blower 100 blows wind through the first ventilating slot 211, and at this time, the blower is in the second wind blowing mode, and the wind blown by the blower 100 only includes a uniform annular airflow blown out through the first ventilating slot 211; as shown in fig. 10 and 11, when the wind shielding structure 221 shields the wind inlet of the first ventilating slot 211, the blower blows air through the second ventilating slot 212, and at this time, the blower 100 is in the third wind blowing mode, and the wind blown by the blower 100 only includes the narrowed strip-shaped airflow blown out through the second ventilating slot 212.

Preferably, in this embodiment, the air outlet area of the first ventilating slot 211 is larger than the air outlet area of the second ventilating slot 212, and the air outlet areas of the first air outlet mode, the second air outlet mode and the third air outlet mode are gradually reduced.

In this embodiment, when the hair dryer 100 is in the first air outlet mode or the second air outlet mode, the hair dryer 100 can blow out annular airflow, and when a user blows hair, the air area of the hair is large, so that the hair can be dried quickly; when the hair dryer 100 is in the third air outlet mode, the hair dryer 100 can blow out a narrowed strip-shaped airflow, so that the wind power is concentrated, and the hair style fixing of a user is facilitated. Therefore, a user only needs to control the first adjusting part 21 and the second adjusting part 22 to rotate relatively according to the needs of the user, so that the wind shielding structure 221 on the second adjusting part 22 shields the air inlet of the first ventilating groove 211 or the second ventilating groove 212 on the first adjusting part 21, and the hair dryer 100 is in different air outlet modes to meet the use requirements, and the air blowing effect can be adjusted without additional accessories; furthermore, the adjusting component 20 is fixed at the air outlet of the hair dryer body 10, and has simple structure and high portability.

It should be noted that, in other embodiments, when the distance between the adjacent first air outlets and the gaps 213 in the circumferential direction is greater than the distance between the adjacent first air outlets and the gaps 213 in the circumferential direction, in the process that the second adjusting member 22 rotates relative to the first adjusting member 21 in the circumferential direction, the wind blocking sheet of the wind blocking structure 221 only blocks at least part of the air inlets of the first ventilation slots 211 or at least part of the air inlets of the second ventilation slots 212, that is, the blower 100 only has the second air outlet mode and the third air outlet mode, which can also meet different use requirements of users.

It is understood that, in other embodiments, the wind shielding structure 221 is not fixedly connected with the blocking piece 23, that is, when the adjusting assembly 20 does not include the blocking piece 23, the second ventilating slot 212 is directly communicated with the inner cavity of the hair dryer body 10, the air flow generated by the hair dryer 100 can be always blown out through the second ventilating slot 212, the wind shielding structure 221 is only used for shielding or exposing the air inlet of the first ventilating slot 211, and the hair dryer 100 only has the first wind outlet mode and the third wind outlet mode, which can also meet different use requirements of users.

The foregoing is illustrative of embodiments of the present invention, and it should be noted that various modifications and adaptations can be made by those skilled in the art without departing from the principle of the embodiments of the present invention, and are intended to be within the scope of the present invention.
