Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

For the purpose of facilitating understanding of the embodiments of the present application, the following description will be made in terms of specific embodiments with reference to the accompanying drawings, which are not intended to limit the embodiments of the present application.

The handheld blower 1 is integrally cylindrical, the upper end of the handheld blower comprises a capsule-shaped vortex cavity 2, an air inlet 3 is formed in the lower portion of the vortex cavity, a fan 4 is preferably arranged at the air inlet 3, air is conveyed into the vortex cavity through the fan, an air outlet 5 is formed in the side wall of the vortex cavity, when the air conveyed by the fan enters the vortex cavity, the air pressure inside the vortex cavity 2 is higher, the air pressure outside the vortex cavity is lower, and therefore the air inside the vortex cavity tends to be discharged outwards, and due to the capsule-shaped structure of the vortex cavity, the air forms a vortex in the cavity through the guiding of the cavity wall and then is discharged through the air outlet, as shown in fig. 3.

The use of the capsule type vortex cavity can significantly reduce the volume of the hair dryer, so that the hair dryer can be formed into a rod shape, and has the function of pressurization, which is beneficial to providing larger air volume. With the structure, if the gas is heated in the vortex cavity, the structure has a substantial significance for substantially reducing the volume of the exhaust fan and sending uniform hot air.

However, in such an environment, by providing the heating device in the vortex chamber 2, the heating of the outlet air medium can be achieved while forming a vortex, which is a substantial help to reduce the length of the blower, and at the same time, the volume of the blower is significantly reduced compared to an annular vortex chamber. However, in this case, the heating wires in the vortex chamber are often not arranged particularly much and completely uniformly, since the volume of the vortex chamber is not very large, which can lead to uneven heating of the air. In order to make full use of the swirl path, in such blowers, heating means are preferably provided comprising a support 6 arranged along the length of the swirl chamber; and a heating wire 7 which is arranged to wrap around the bracket. The bracket comprises two longitudinally extending plates spaced from each other, the two longitudinally extending plates dividing the vortex chamber into three relatively isolated sections; the outlet opening is opposite the spaced region between the two longitudinally extending plates.

In this case, the vortex path of the capsule-shaped vortex chamber is used, but the air at the edge of the chamber is often heated well and the air in the middle of the chamber is heated to a different degree than at the edge, resulting in uneven heating. Under the condition, the gas forms vortex in the cavity through the direction of the cavity wall and then is discharged through the air outlet, as shown in fig. 3, the discharged wind is uneven in temperature, and the using effect is affected.

In the present invention, the shape of the outlet is matched with the shape of the cross section of the vortex chamber, and since the shape of the vortex chamber is capsule-shaped, the cross section of the vortex chamber is rounded rectangle, so that the cross section of the outlet is also set to be rounded rectangle or the shape similar to the rounded rectangle, thereby realizing matching. For example, one shape includes a cross-sectional shape of the outlet port including arcs at both ends, and a straight line connecting the arcs at both ends.

Under the condition that the air outlet is in the shape, because the medium is obviously guided by the inner wall of the cavity in the vortex cavity, the air at different positions in the cavity can easily flow to the corresponding positions of the air outlet. For example, as shown in fig. 3, most of the wind on both sides will flow out from both sides of the outlet, and most of the wind in the middle will flow out from the middle of the outlet.

In this embodiment, the outlet comprises an outlet wall 8 extending outwardly from the vortex chamber side wall, the outlet wall of the outlet tapering from the periphery 9 towards the centre and then extending outwardly in a straight line. Due to the narrowing of the air outlet wall, the discharged air flow is firstly concentrated under the guidance of the narrowed air outlet wall, and the air flow can be mixed to a certain extent to complete the first homogenization.

Further, in this embodiment, the central portion of the outlet is provided with a ring 10, the ring gradually rises from the periphery of the outlet to the center, a first gap 11 is included between the outer periphery of the ring and the wall of the outlet, and the ring has a second gap 12. The wind with higher temperature from the edge of the vortex cavity is usually in the first gap, the wind at the edge gathers together again under the guidance of the raised shape of the ring to the center of the wind outlet, and the wind outlet center has a second gap which is reduced from inside to outside, so that most of the air flow in the middle of the vortex cavity is discharged from the second gap, and the secondary mixing is completed. Under the two times of mixing, the gases with different temperatures can be fully diffused, thereby forming uniform wind.

Further preferably, the shape of the ring is the same as the cross-sectional shape of the outlet. The guiding rule of the ring is more obvious, and the gas mixing is more facilitated.

Furthermore, the ring is fixedly connected with the inner wall of the air outlet through a connecting rod 13, so that the ring is fixed, and the integral strength of the wall of the air outlet is improved.

Still further, a circle of metal layer 14 is arranged on the inner side of the air outlet wall. The metal layer can protect the air outlet wall and avoid being scalded by hot air with high temperature.

The above-mentioned embodiments, objects, technical solutions and advantages of the present application are described in further detail, it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present application, and are not intended to limit the scope of the present application, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present application should be included in the scope of the present application.
