Diffuser

Abstract

Disclosure is a diffuser including shell, first diffusion component, second diffusion component, and air output component. The shell includes an air inlet, the air inlet is configured to receive an airflow from a hair dryer. The first diffusion component is detachably connected to the shell, includes a first through hole; the airflow flowing out of the air inlet passes through the first through hole. The second diffusion component is detachably connected to the first diffusion component, includes a second through hole; an inner surface of the second through hole is a conical surface contracted towards the first diffusion component; the airflow flowing out of the first through hole passes through the second through hole. The air output component is detachably connected to the shell and the second diffusion component, and is configured to guide the airflow flowing out of the second through hole to flow out of the diffuser.

What is claimed is: 
     
         1 . A diffuser, wherein the diffuser comprises:
 a shell, comprising an air inlet; wherein the air inlet is configured to receive an airflow from a hair dryer;   a first diffusion component, detachably connected to the shell, comprising a first through hole; wherein the airflow flowing out of the air inlet passes through the first through hole;   a second diffusion component, detachably connected to the first diffusion component, comprising a second through hole; wherein an inner surface of the second through hole is a conical surface contracted towards the first diffusion component, and the airflow flowing out of the first through hole passes through the second through hole; and   an air output component, detachably connected to both the shell and the second diffusion component, configured to guide the airflow flowing out of the second through hole to flow out of the diffuser.   
     
     
         2 . The diffuser according to  claim 1 , wherein a contour shape of the second diffusion component is a frustum of a cone, and the second diffusion component is contracted towards the first diffusion component. 
     
     
         3 . The diffuser according to  claim 2 , wherein the second through hole is an annular through hole. 
     
     
         4 . The diffuser according to  claim 3 , wherein the second through holes are spaced at the second diffusion component around an axis of the second diffusion component. 
     
     
         5 . The diffuser according to  claim 4 , wherein a quantity of the second through holes is three. 
     
     
         6 . The diffuser according to  claim 1 , wherein the air output component is snapped with the shell, and abuts against the second diffusion component. 
     
     
         7 . The diffuser according to  claim 6 , wherein the first diffusion component abuts against both the shell and the second diffusion component, and the second diffusion component is in a threaded connection with the shell for fixing the first diffusion component between the second diffusion component and the shell. 
     
     
         8 . The diffuser according to  claim 1 , wherein the air output component comprises first air-outputting through holes and second air-outputting through holes; the airflow flowing out of the second through hole passes through both the first air-outputting through holes and the second air-outputting through holes, and flows out of the diffuser; the first air-outputting through holes are distributed in an annular and arrayed manner at a middle part of the air output component; the second air-outputting through holes are distributed in an annular and arrayed manner at an edge part of the air output component, and surround the first air-outputting through holes; a contour shape of the first air-outputting through hole is an ellipse, and a contour shape of the second air-outputting through hole is a parallelogram with a rounded corner. 
     
     
         9 . The diffuser according to  claim 8 , wherein the air output component further comprises an air output column; the airflow flowing out of the second through hole passes through the air output column and flows out of the diffuser. 
     
     
         10 . The diffuser according to  claim 1 , wherein a contour shape of the first diffusion component is a frustum of a cone, and the first diffusion component is contracted towards the shell; two ends of the first diffusion component are connected to form a conical through hole, and the first through holes are distributed in an annular and arrayed manner at an inner surface of the conical through hole.
