Referring to fig. 1 and 2, the present invention provides a diffuser 100 for a blower 1000.

In an embodiment of the present invention, the diffuser 100 includes a housing 10 and an air outlet 30. The casing 10 has an air inlet end 11a and an air outlet end 13a, and the air inlet end 11a is used for communicating with the blower body 300 of the blower 1000; the air outlet portion 30 is communicated with the air outlet end 13a, the air outlet portion 30 is provided with an air expanding hole 30a and an air outlet hole 30b, the air outlet direction of the air expanding hole 30a is arranged towards the center of the air outlet end 13a, and the air outlet direction of the air outlet hole 30b is parallel to the extension direction of the center line of the air outlet portion 30.

In an embodiment of the present invention, the casing 10 is mainly used to form an air guiding channel to guide the airflow blown out by the blower body 300 to increase the contact area with hair. Specifically, the casing 10 may have a substantially circular truncated cone shape, and the cross-sectional area of the casing 10 gradually increases from the air inlet end 11a to the air outlet end 13 a. Thus, the air flow blown out from the fan body 300 can flow to the air outlet end 13a along the extending direction of the inner wall of the casing 10, so as to increase the air outlet area; the circular truncated cone shaped housing 10 can make the air flow velocity at all positions of the inner peripheral surface of the housing 10 the same, so that the air flow blown by the blower 1000 at all positions is more uniform to further improve the blowing effect. Additionally, to reduce the mass of the blower 1000 so that it is convenient for a user to hold it in his or her hand. The material of the housing 10 may be plastic material, for example: ABS, POM, PS, PMMA, PC, PET, etc. The air inlet end 11a is mainly used for communicating with the blower body 300, and specifically, a through hole communicated with the blower body 300 is formed to communicate with the blower body. The air inlet end 11a and the blower body 300 may be fixedly connected to each other in an integrated structure, so as to improve the connection strength between the diffuser 100 and the blower body 300. Of course, the air inlet end 11a and the blower body 300 may also be detachably connected like a screw, a buckle or a magnet, so as to be conveniently detached for maintenance and replacement. The air outlet portion 30 is mainly used for receiving the air flow in the housing 10, making the air flow out from the air expanding holes 30a and the air outlet holes 30b to form diversified air blowing directions, and increasing the air outlet amount of the air outlet portion 30 by the expanding effect of the air expanding holes 30a on the air volume. The air outlet 30 may be protruded from the surface of the air outlet end 13a, and may be substantially shaped as a body, so that when the diffuser 100 blows air to the user, it may contact the scalp, so that a certain distance exists between the diffuser 100 and the hair, thereby preventing the hair from being stuck to the diffuser 100 due to the too close distance between the diffuser 100 and the hair. Wherein, air-out portion 30 and air-out end 13a can be the setting of structure as an organic whole, so avoid both to have the clearance and influence the leakproofness in the junction. In order to avoid the scalp from being scratched by the air outlet 30, an end surface of the air outlet 30 away from the air outlet end 13a and a lateral periphery of the air outlet 30 may be smoothly transited.

The utility model discloses a when diffuser 100 of technical scheme was applied to hair-dryer 1000, through the air inlet end 11a and the hair-dryer 1000 body intercommunication on the casing 10 of diffuser 100 for the air current that the hair-dryer 1000 body blew out is held 11a by the air inlet and is got into in the casing 10, and flows from the air-out end 13a on the casing 10 behind diffuser 100's the guide effect. Because the diffuser 100 in this scheme has air-out portion 30 in air-out end 13a intercommunication, be equipped with on this air-out portion 30 and expand wind hole 30a and exhaust vent 30b, and expand the wind direction of wind hole 30a and set up towards the center of air-out end 13a, the extending direction of the air-out direction of exhaust vent 30b and the central line of air-out portion 30 is parallel arrangement. Therefore, the air flow flowing out of the casing 10 can enter the air outlet portion 30, and can partially flow out through the air diffusing holes 30a and partially flow out through the air outlet holes 30b, that is, the diffuser 100 has different air outlet directions. Therefore, compared with the prior art in which the diffuser 100 of the blower 1000 can only output air in a linear shape along the side of the diffuser 100 away from the blower body 300, the air output direction of the diffuser 100 of the blower 1000 in the present embodiment is diversified, and the contact area with hair is increased, thereby improving the blowing effect of the blower 1000. Meanwhile, the air diffusing holes 30a have an effect of expanding the air volume blown out by the diffuser 100, and can increase the air volume of the diffuser 100 in the air outlet portion 30, so as to enhance the drying and shaping effects of the air flow blown out by the diffuser 100 on the hair of the user, thereby further improving the blowing effect of the hair dryer 1000.

Referring to fig. 2, in an embodiment of the present invention, the air diffusing holes 30a are disposed on the side periphery of the air outlet portion 30, and the air outlet holes 30b are disposed on the end surface of the air outlet portion 30 away from the air outlet end 13 a.

It can be understood that the arrangement makes the air-diffusing holes 30a and the air-discharging holes 30b more dispersed, i.e. there is a larger space for arranging on the outer peripheral surface of the air-discharging portion 30 and the side end surface far from the air-discharging end 13a, so as to facilitate the arrangement of the two. Meanwhile, the end face of the air outlet part 30, which is far away from the air outlet end 13a, is provided with the air outlet hole 30b, so that the air flow in the air outlet part 30 can linearly flow out, and the air outlet speed of the air flow is ensured. Of course, the present application is not limited thereto, and in other embodiments, the air diffusing hole 30a may also be disposed on an end surface of the air outlet portion 30 away from the air outlet end 13a, and led out through the guiding segment; the outlet opening 30b can also be provided with the lateral surface of the outlet portion 30 and can likewise be led out through the guide section.

In an embodiment of the present invention, the air expanding hole 30a is formed in a long strip shape, and is formed by extending along a side of the air outlet portion 30 away from the air outlet end 13a to a side of the air outlet portion 30 close to the air outlet end face 13 b.

It can be understood that the spoiler holes 50a are disposed such that the diffuser 100 blows the air flow toward the center of the wind outlet end 13a and/or the periphery of the wind outlet end 13a at the spoiler portion 50, and disturbs the air flow blown by the wind outlet portion 30. Thus, the fluidity of the air flow blown out from the air outlet portion 30 can be improved, and the air flow blown out from the air outlet portion 30 can be relatively disordered and have more diversified flow directions, so that the blowing effect of the diffuser 100 can be further improved. The air outlet direction of the turbulent flow hole 50a may be toward the center of the air outlet end 13a, or toward the periphery of the air outlet end 13a, or both the center of the air outlet end 13a and the periphery of the air outlet end 13 a. Further, the spoiler 50 and the air outlet end 13a may be integrally formed, so as to prevent the occurrence of a gap at the joint therebetween and thus the sealing performance of the spoiler is not affected. The spoiler 50 may be formed to be protruded from the surface of the air outlet end 13a and be substantially in a main body shape so as to be brought into contact with the scalp when the diffuser 100 blows air to the user. In order to avoid the turbulent flow portion 50 from scratching the scalp, the end surface of the turbulent flow portion 50 away from the air outlet end 13a and the lateral circumferential surface of the turbulent flow portion 50 may be smoothly transited.

In an embodiment of the present invention, the turbulent flow hole 50a penetrates through the side circumference of the turbulent flow portion 50, so that the air outlet direction of the turbulent flow hole 50a faces the center of the air outlet end 13a and the periphery of the air outlet end 13 a.

It can be understood that the through arrangement of the spoiler hole 50a enables the air flow in the spoiler 50 to flow out towards the center of the air outlet end 13a and the periphery of the air outlet end 13a, i.e. the air flow can be blown out from different directions to increase the spoiler effect of the spoiler 50 on the air outlet portion 30, so as to further increase the flowability and direction diversity of the air flow and improve the blowing effect of the diffuser 100.

In an embodiment of the present invention, the spoiler 50a is formed in a long strip shape and extends along a side of the spoiler 50 away from the air outlet end 13a to a side of the spoiler 50 close to the air outlet end 13 a.

It can be understood that the air outlet area of the turbulent flow hole 50a is increased by the arrangement, so that the turbulent flow effect of the turbulent flow part 50 on the air outlet part 30 can be increased, and the blowing effect of the diffuser 100 can be improved. The spoiler hole 50a may also be formed by cutting off a part of the spoiler portion 50 from the end surface far away from the air outlet end 13a along the side close to the air outlet end 13a, so as to simplify the forming process of the spoiler hole 50 a.

In an embodiment of the present invention, the air outlet portion 30 is close to the periphery of the air outlet end 13a, and the spoiler portion 50 is close to the center of the air outlet end 13 a.
