Referring to FIGS. 1, 5, and 6, the present disclosure provides a diffuser 100, which includes a shell 110, a first diffusion component 120, a second diffusion component 130, and an air output component 140. The shell 110 is arranged with an air inlet 1112. The air inlet 1112 is used to receive an airflow from an air-inputting end of a hair dryer (not shown in the Figures), and is used to guide the airflow to flow out of the shell 110. The first diffusion component 120 is detachably connected to the shell 110; in some embodiments, the first diffusion component 120 abuts against the shell 110. The first diffusion component 120 is arranged with a first through hole 123, and the first through hole 123 is used to guide the airflow which flows out of the air inlet 1112 to flow in the direction of the second diffusion component 130; among them, the airflow flowing out of the air inlet 1112 passes through the first through hole 123 and is away from the shell 110. The second diffusion component 130 is detachably connected to the first diffusion component 120; in some embodiments, the second diffusion component 130 abuts against the first diffusion component 120. The second diffusion component 130 is arranged with a second through hole 134, and the second through hole 134 is used to guide the airflow which flows out of the first through hole 123 to flow in the direction of the air output component 140. An inner surface of the second through hole 134 is a conical surface that contracts in the direction of the first diffusion component 120, so that the airflow passing through the second through hole 134 flows to the air output component 140 in a conical diffusion manner; among them, the airflow flowing out of the first through hole 123 passes through the second through hole 134 and is away from both the first diffusion component 120 and the shell 110. The air output component 140 is detachably connected to the second diffusion component 130; in some embodiments, the air output component 140 abuts against the second diffusion component 130. The air output component 140 is further detachably connected to the shell 110; in some embodiments, the air output component 140 and the shell 110 are connected together by means of a snap-in connection. When the air output component 140 is connected to the shell 110, both the first diffusion component 120 and the second diffusion component 130 are fixed in an internal space formed by both the air output component 140 and the shell 110. The air output component 140 is used to guide the airflow which passes through the second through hole 134 to flow out of the diffuser 100, thereby achieving air output. The airflow flowing out of the second through hole 134 passes through the air output component 140, and is away from all the second diffusion component 130, the first diffusion component, and the shell 110.
In the above embodiments of the present disclosure, the first through hole is arranged at the first diffusion component to guide the airflow which flows out of the shell, so that the airflow can flow in the direction of the second diffusion component after passing through the first through hole; and the second through hole is arranged at the second diffusion component to guide the airflow which flows out of the first through hole, and the inner surface of the second through hole is set as a conical surface contracting in the direction of the first diffusion component, so that the airflow can flow in a conical diffusion manner in the direction of the air output component after passing through the second through hole, so as to ensure an even flow rate of the airflow exported from an edge part of the air output component and the airflow exported from a middle part of the air output component, and ensure an even flow capacity of the airflow exported from the edge part of the air output component and the airflow exported from the middle part of the air output component, thereby making the airflow outputting by the diffuser even.
In some embodiments of the present disclosure, continuing to refer to FIGS. 1 and 3, the shell 110 may be set to a substantially funnel-shaped structure as shown in FIG. 1, but not limited to thereto. The shell 110 includes a first narrow end 111 away from the air output component 140, and a first broad end 112 close to the air output component 140. The first narrow end 111 is arranged with a first connection portion 1111, and is arranged with the air inlet 1112 surrounding the first connection portion 1111. The first connection portion 1111 is detachably connected to both the first diffusion component 120 and the second diffusion component 130; in some embodiments, the first connection portion 1111 abuts against the first diffusion component 120, and the first connection portion 1111 is in a threaded connection with the second diffusion component 130. The air inlet 1112 is used to receive airflow from an air-inputting end of a hair dryer (not shown in the Figures). In some embodiments, the air inlet 1112 may be configured as, but not limited to, an annular through-hole structure as shown in FIGS. 1 and 3. In some embodiments, a first snap-in portion 1121 is arranged at an inner wall of the shell 110, and the inner wall of the shell 110 is close to the first broad end 112. The first snap-in portion 1121 and the air output component 140 are connected together by means of a snap-in connection. When the first snap-in portion 1121 and the air output component 140 are connected together by means of the snap-in connection, both the first diffusion component 120 and the second diffusion component 130 are fixed in an internal space formed by both the air output component 140 and the shell 110.
In some embodiments of the present disclosure, continuing to refer to FIGS. 1 and 4, the first diffusion component 120 may be set to a funnel-shaped structure as shown in FIG. 1, but not limited thereto; and a contour shape of the first diffusion component 120 may be set to a frustum of a cone as shown in FIG. 4, but not limited thereto. The first diffusion component 120 includes a first end 121 close to the first narrow end 111 (i.e. the first end 121 is away from the second diffusion component 130), and a second end 122 away from the first narrow end 111 (i.e. the second end 122 is close to the second diffusion component 130). The first end 121 surrounds the first connection portion 1111 and abuts against the first connection portion 1111; in some embodiments, the first end 121 is in a clearance fit with the first connection portion 1111. The second end 122 abuts against the second diffusion component 130. In some embodiments, contour shapes of the first end 121 and the second end 122 may be set to, but are not limited to, be elliptic as shown in FIG. 1. A conical through hole is formed between the first end 121 and the second end 122 which are interconnected together, and an inner surface of the conical through hole is a conical surface that contracts in the direction of the first end 121 (i.e. in the direction of the shell 110). The first through holes 123 are located between the first end 121 and the second end 122, and are distributed in an annular and arrayed manner on the inner surface of the conical through hole, avoiding the airflow which flows out of the first through holes 123 from being mainly dispersed at an edge part of the second diffusion component 130 before the airflow flowing into the second through hole 134, avoiding resulting in uneven air output. The first through hole 123 is used to guide the airflow which flows out of the air inlet 1112 in a direction that is substantially parallel to the second diffusion component 130, among them, after the airflow which flows out of the air inlet 1112 passes through the first through hole 123, each airflow which flows out of each first through hole 123 is substantially parallel to each other, and flows in a cylinder-shaped manner in the direction of the second diffusion component 130. In some embodiments, a contour shape of the first through hole 123 may be set to, but not limited to, an ellipse as shown in FIG. 4.
In the above embodiments of the present disclosure, the conical through hole is arranged at the first diffusion component, and the first through holes are set in an annular and arrayed manner on the conical surface of the conical through hole, so as to guide the airflow which flows out of the shell by the first through hole, so that after the airflow passes through the first through hole, each airflow flowing out of each first through hole is substantially parallel to each other, and flows in a cylinder-shaped manner in the direction of the second diffusion component, thereby ensuring an even flow rate of the airflow flowing from each first through hole to the second diffusion component, and ensuring an even flow capacity of the airflow flowing from each first through hole to the second diffusion component.
In some embodiments of the present disclosure, continuing to refer to FIGS. 1, 5, and 6, a contour shape of the second diffusion component 130 may be set to, but not limited to, a frustum of a cone as shown in FIGS. 5 and 6; in some embodiments, the contour shape of the second diffusion component 130 is the frustum of a cone, and the second diffusion component 130 contracts in the direction of the first diffusion component 120; that is to say, a side surface of the second diffusion component 130 with its contour shape of the frustum of a cone is a conical surface, and the conical surface contracts in the direction of the first diffusion component 120. The second diffusion component 130 includes a second narrow end 131 close to the second end 122 (i.e. the second narrow end 131 is away from the air output component 140), a second broad end 132 away from the second end 122 (i.e. the second broad end is close to the air output component 140), and a second connection portion 133 penetrating through both the second narrow end 131 and the second broad end 132. The second connection portion 133 is located at a middle part of the second diffusion component 130. Contour shapes of the second narrow end 131 and the second broad end 132 may be set to, but not limited to, be elliptic as shown in FIGS. 5 and 6. One end of the second connection portion 133 close to the first diffusion component 120 is surrounded by the first end 121 of the first diffusion component 120, and abuts against the first connection portion 1111; in some embodiments, one end of the second connection portion 133 close to the first diffusion component 120 is snapped into the first connection portion 1111. One end of the second connection portion 133 close to the air output component 140 abuts against the air output component 140. In some embodiments, the first connection portion 1111 is provided with a column with screw hole 11111, the second connection portion 133 is provided with a screw hole 1331; both the second connection portion 133 and the first connection portion 1111 are fixedly connected together by a screw 150 passing through the screw hole 1331 and then being screwed with the column with screw hole 11111. Due to the first diffusion component 120 abutting against both the shell 110 and the second diffusion component 130, when the second connection portion 133 and the first connection portion 1111 are screwed together, the first diffusion component 120 is fixed between the second diffusion component 130 and the shell 110.
In some embodiments of the present disclosure, continuing to refer to FIGS. 1, 5, and 6, the second through hole 134 is holed through both the second narrow end 131 and the second broad end 132, and surrounds the second connection portion 133. The second through hole 134 may be configured as, but not limited to, an annular through-hole structure as shown in FIGS. 5 and 6. In some embodiments, the second through hole 134 is an annular through hole, and an inner surface of the second through hole 134 is a conical surface which contracts in the direction of the first diffusion component 120 to facilitate the airflow flowing in from the second through hole 134 to flow out in a conical diffusion manner. The number of the second through hole 134 may be set to one or more; in some embodiments, the second through hole 134 is multiple, and multiple second through holes 134 surround an axis of the second diffusion component, and are spaced on the second diffusion component 130; in one implementation, the number of the second through hole 134 is set to three, so as to avoid the airflow which flows from the second through hole 134 from centrally flowing out of a middle part of the second diffusion component 130 causing by an excessive quantity of the second through holes 134, and to avoid the airflow which flows from the second through hole 134 from dispersively flowing out of an edge part of the second diffusion component 130 causing by an insufficient number of the second through holes 134, i.e. to avoid uneven airflow from the middle part of the second diffusion component 130 and the edge part of the second diffusion component 130.
In some embodiments of the present disclosure, continuing to refer to FIGS. 1, 2, and 7, the air output component 140 may be set to, but not limited to, a substantially disc-shaped structure as shown in FIGS. 1 and 7. A third connection portion 141 is arranged at a middle part of one end of the air output component 140, and the one end of the air output component 140 is close to the second diffusion component 130. The third connection portion 141 abuts against one end of the second connection portion 133, and the one end of the second connection portion 133 is close to the air output component 140; in some embodiments, the third connection portion 141 is in a clearance fit with the one end of the second connection portion 133, and the one end of the second connection portion 133 is close to the air output component 140. A second snap-in portion 142 is arranged at one end of the air output component 140, and the one end of the air output component 140 is close to the second diffusion component 130, and the second snap-in portion 142 surrounds the third connection portion 141. The second snap-in portion 142 is snapped into the first snap-in portion 1121, among them, when the second snap-in portion 142 is snapped into the first snap-in portion 1121, both the first diffusion component 120 and the second diffusion component 130 are fixed in an internal space formed by both the air output component 140 and the shell 110.
In some embodiments of the present disclosure, continuing to refer to FIGS. 1, 2, and 7, a surface of the air output component 140 is provided with a first air-outputting through hole 143 and a second air-outputting through hole 144. The first air-outputting through hole 143 is distributed in an annular and arrayed manner at a middle part of the air output component 140. The second air-outputting through hole 144 is distributed in an annular and arrayed manner at an edge part of the air output component 140, and surrounds the first air-outputting through hole 143. A contour shape of the first air-outputting hole 143 is an ellipse to ensure that each airflow flowing out of each first air-outputting hole 143 is concentrated in the middle part of the air output component 140; a contour shape of the second air-outputting hole 144 is a parallelogram with rounded corners to ensure that each airflow flowing out of each second air-outputting hole 144 disperses to the edge part of the air output component 140. In some embodiments, the air output component 140 further includes an air output column 145 for partially guiding the airflow which flows out of the second through hole 134 to flow out of the diffuser 100, that is, the airflow which flows out of the second through hole 134 partially passes through the air output column and then flows out of the diffuser to ensure even airflow. The number and arrangement of the air output column 145 are not limited here.
In the above embodiments of the present disclosure, the elliptical first air-outputting through hole is distributed in an annular and arrayed manner at a middle part of the air output component; the second air-outputting through hole having a shape of parallelogram with rounded corners is distributed in an annular and arrayed manner at an edge part of the air output component, and surrounds the first air-outputting through hole, so that the flow rate of the airflow exported from the middle part of the air output component and the airflow exported from the edge part of the air output component is even, and the flow capacity of the airflow exported from the middle part of the air output component and the airflow exported from the edge part of the air output component is even, thereby ensuring even air output.
