Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] refer to Figures 1 to 6 A portable clothes dryer blowing structure, including an air duct 1; The bottom of the air duct 1 is provided with an air inlet 11, and the top of the air duct 1 is provided with an air outlet 12; The air inlet 11 is equipped with a fan 5, which is inserted into the air inlet 11. A first air guide section 2 is provided above the air inlet 11; The air outlet 12 is equipped with a second air guide section 3; A PTC heating element 4 is provided between the first air guide section 2 and the second air guide section 3.

[0015] refer to Figure 6 The first air guide section 2 includes a first air guide 21 and a second air guide 22 symmetrically arranged. Both the first air guide 21 and the second air guide 22 are inclined outward, for example, the first air guide 21 is inclined to the left and the second air guide 22 is inclined to the right. The second air guide section 3 includes a third air guide vane 31 and a fourth air guide vane 32 arranged symmetrically. Both the third air guide vane 31 and the fourth air guide vane 32 are inclined outwards. For example, the third air guide vane 31 is inclined to the left and the fourth air guide vane 32 is inclined to the right.

[0016] Therefore, the fan 5 generates airflow, which flows in through the air inlet 11 and out through the air outlet 12. Under the action of the first air guide 2, the airflow diffuses to the left and right sides, causing the airflow to flow evenly towards the air outlet 12. Under the action of the second air guide 3, the airflow diffuses to the left and right sides and flows out, which helps to increase the blowing area and improve the drying effect.

[0017] The PTC heating element 4 can heat the airflow to create hot air and improve the drying effect.

[0018] Fan 5 can be a high-speed fan, which can provide strong airflow to ensure drying effect.

[0019] refer to Figure 1 and Figure 2 The air inlet 11 is circular and the air outlet 12 is rectangular. The size of the air outlet 12 is larger than that of the air inlet 11. The air inlet 11 is roughly opposite the middle of the air outlet 12. In this way, the first air guide 2 directs the airflow to the air outlet 12 in a diffused manner, thereby improving the uniformity of the airflow.

[0020] refer to Figure 1The length L of the blower structure is less than or equal to 200mm, and the width W is less than or equal to 100mm. Preferably, the length L is less than or equal to 150mm, and the width W is less than or equal to 70mm; this size design makes the blower structure easy to carry, thereby reducing the size of the dryer and making it convenient for outdoor use such as travel and camping.

[0021] refer to Figure 6 Multiple first air guide vanes 21 and multiple second air guide vanes 22 are arranged in each direction; Along the direction away from the center, the angle θ1 between the multiple first air guide vanes 21 and the horizontal plane gradually decreases; for example, if two first air guide vanes 21 are provided, the angle θ1 gradually decreases along the direction away from the center, that is, the inclination relative to the vertical direction gradually increases. Along the direction away from the center, the angle θ2 between the multiple second air guide vanes 22 and the horizontal plane gradually decreases; for example, if two second air guide vanes 22 are set, the angle θ2 gradually decreases along the direction away from the center, that is, the inclination relative to the vertical direction gradually increases; thus, it is beneficial to better diffuse the airflow to the left and right.

[0022] refer to Figure 6 Both the third air guide vane 31 and the fourth air guide vane 32 are provided with multiple vanes; The angle β1 between the third air guide 31 and the horizontal plane is greater than the angle θ1 between the first air guide 21 and the horizontal plane, meaning that the tilt of the third air guide 31 is smaller. The angle β2 between the fourth guide vane 32 and the horizontal plane is greater than the angle θ2 between the second guide vane 22 and the horizontal plane, that is, the tilt of the fourth guide vane 32 is smaller. Therefore, the second air guide 3 is used to appropriately diffuse the airflow outward to increase the blowing area. Thus, the inclination is relatively small, which achieves an appropriate increase in the blowing area and avoids large airflow resistance that weakens the airflow intensity, thereby achieving a balance between the blowing area and the airflow intensity.

[0023] refer to Figure 2 The PTC heating element 4 has a corrugated structure, forming a permeable hollow structure. The PTC heating element 4 can be inserted into the air duct 1 with an interference fit or assembled into the air duct 1 with a snap-fit ​​structure. The edge of the PTC heating element 4 is provided with a limiting piece 41, and the side wall of the air duct 1 is provided with a limiting groove 61 that cooperates with the limiting piece 41, thereby achieving limiting and error prevention, and improving assembly accuracy and convenience.

[0024] refer to Figure 2The blower structure includes an upper housing 6 and a lower housing 7; the internal space formed by the upper housing 6 and the lower housing 7 constitutes the air duct 1; the upper housing 6 and the lower housing 7 can be assembled by screws, bolts or clips; in order to improve the sealing performance, the connection between the upper housing 6 and the lower housing 7 is provided with a skirt or a raised lip, and a sealing ring or a sealing gasket can also be provided. The upper housing 6 is provided with an air outlet 12, a second air guide 3 and a limiting groove 61, and the lower housing 7 is provided with an air inlet 11 and a first air guide 2.

[0025] refer to Figure 3 and Figure 4 The lower housing 7 includes a first component 71 and a second component 72. The first component 71 is provided with a plurality of first pieces 711, and the second component 72 is provided with a plurality of second pieces 721. The plurality of first pieces 711 and the plurality of second pieces 721 are connected one by one to form a first air guide 21 and a second air guide 22. The lower housing 7 is assembled from the first component 71 and the second component 72, which facilitates the mold manufacturing of the lower housing 7. The first component 71 and the second component 72 can be assembled by screws, bolts or buckles.

[0026] refer to Figure 3 and Figure 4 The first piece 711 has ribs 712 on both its upper and lower surfaces. The two ribs 712 are arranged opposite each other. The cross-sectional shape of the ribs 712 is arc-shaped or semi-circular, which helps to reduce wind resistance. The two ribs 712 extend along the length of the first piece 711 and extend out of the end of the first piece 711, thereby forming a groove 713. The end of the second piece 721 is inserted into the groove 713, thereby improving the connection accuracy between the first piece 711 and the second piece 721.

[0027] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
