Background

The noise of modern hair dryers mainly comprises: motor noise, air flow noise, structural resonance noise, and air resonance noise, wherein the air flow noise is noise generated by an air flow generated by a blower.

The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In addition, the technical features described above in the different embodiments of the present utility model may be combined with each other as long as they do not collide with each other.

In one aspect, the present utility model provides a blower, as shown in fig. 1, 2, 3, 4, 5 and 6, as a home appliance, which can be used in daily bathing, beauty, drying, etc., by driving the movement of the blades by a motor rotating at a high speed, generating an air stream, blowing air onto the hair or objects, and causing them to dry or cool rapidly. The main structure comprises: the air blower comprises an air blower body 1, a handle 2 and a control component 3, wherein the air blower body 1 comprises an outer shell 11 and an air duct 12 arranged in the outer shell 11, a first accommodating cavity 121 and a second accommodating cavity 122 which are mutually communicated are formed in the air duct 12, an air inlet 111 and an air outlet 112 which are communicated with the first accommodating cavity 121 and the second accommodating cavity 122 are respectively formed in two ends of the outer shell 11, an air blowing component 13 and an air guide component 14 are respectively arranged in the first accommodating cavity 121 and the second accommodating cavity 122, the handle 2 is arranged on the outer side wall of the outer shell 11, and the control component 3 is arranged on the handle 2; the cross-sectional dimension of the end of the air guiding member 14 near the air outlet 112 is larger than the cross-sectional dimension of the end away from the air outlet 112, and the air guiding member 14 is disposed on the axis of the second accommodating cavity 122, so that the air flow in the second accommodating cavity 122 flows towards the outer side of the air guiding member 14. Preferably, the outer shell 11 and the air duct 12 are both cylindrical in structural design. The respective air guide members 14 are configured in a cylindrical structure. Specifically, the cross-sectional dimension of the air guiding member 14 near one end of the air outlet 112 is larger than the cross-sectional dimension of the other end, i.e. the dimension of the air outlet 112 is reduced, the air flow in the second accommodating cavity 122 is blocked at the air outlet 112, the pressure in the second accommodating cavity 122 is increased, and the air flow blown out from the air outlet 112 can be more blown.

When air flows in a narrow duct, vortices and turbulence are easily formed due to friction, speed difference, and the like, thereby causing noise. In some low-grade blowers with simpler designs, due to the limitations of manufacturing process, material cost and the like, the design of an air duct of the blower may not be optimized enough, vortex phenomenon noise is easy to occur, and the use experience of consumers is further reduced. According to the scheme of the utility model, the air flow in the second accommodating cavity 122 is uniformly dispersed to the side wall through the air guide member 14, so that noise generated by air flow vortex caused by turbulence of the air flow in the second accommodating cavity 122 is avoided. The air flow vortex in the second accommodating cavity 122 is effectively reduced through the air guide member 14, so that vibration and noise generated by vortex are reduced, and the effect of reducing noise is realized. In addition, the structure of the two ends of the wind guiding member 14 is optimized, and one end of the wind guiding member 14, against which wind is blown, is provided with a semicircular arc structure with smaller resistance. The other end linearly expands the size of the air outlet 112, so that the pressure in the second accommodating cavity 122 is increased, and the air flow blown out by the air outlet 112 can be more wind.

Further, as shown in fig. 4 and 5, the size of the first receiving chamber 121 is smaller than that of the second receiving chamber 122. The second accommodating chamber 122 accommodates more components and parts, and the air duct needs to be optimized, so that the size of the first accommodating chamber 121 is smaller than that of the second accommodating chamber 122.

Further, as shown in fig. 4, 5 and 6, a plurality of heating ribs 123 are uniformly provided on the inner sidewall of the second accommodating chamber 122, the heating ribs 123 are used for heating air, and the air guiding member 14 is fixed on the axis of the second accommodating chamber 122 through the heating ribs 123.

It should be noted that, in the solution of the present utility model, the air flow inside the second accommodating cavity 122 is uniformly dispersed to the sidewall by the air guiding member 14. The airflow vortex in the second accommodating cavity 122 is effectively reduced, so that the airflow in the second accommodating cavity 122 flows more smoothly, and the heat of the heating ribs 123 can be brought out more smoothly, and the heat accumulation and reddening of the heating ribs 123 are avoided.

Further, as shown in fig. 4 and 5, an arc-shaped portion 1231 is formed at an end of the heating rib 123 adjacent to the first receiving chamber 121.

It should be noted that, the arc-shaped portion 1231 is bent and contracted in the direction of the wind guiding member 14, the arc-shaped portion 1231 of the heating rib 123 may form a buffer structure, so as to prevent the air flow outputted from the first accommodating chamber 121 from directly blowing toward the heating rib 123,

further, as shown in fig. 4 and 5, a semicircular arc portion 141 is disposed at an end of the air guiding member 14 near the first accommodating cavity 121, and an arc convex surface of the semicircular arc portion 141 is a wind striking surface. The wind collision surface is a surface of the semicircular arc part 141 facing the airflow. The surface of the wind striking surface of the semicircular arc part 141 is smooth, and the resistance is smaller when the air current blows to the wind striking surface of the semicircular arc part 141.

It will be appreciated that the semi-circular arc 141 reduces aerodynamic drag and allows for a smoother airflow through the air guide member 14, increasing the airflow velocity. And the air flow flows to the outside of the wind guide member 14 under the guide of the wind striking face of the semicircular arc portion 141. Noise generated by vortex of the air flow generated by turbulence of the air flow in the second accommodating cavity 122 is avoided.

Further, as shown in fig. 4 and 5, the first receiving chamber 121 is connected with the second receiving chamber 122 in sequence, and the opening 1211 of the second receiving chamber 122 toward the first receiving chamber 121 is provided in an arc shape, that is, the respective openings 1211 between the first receiving chamber 121 and the second receiving chamber 122 are the same size.

When the air flows into the second accommodating chamber 122 through the opening 1211, the air directly blows the air guiding member 14, and is spread around the air guiding member 14 under the split flow of the air guiding member 14. Since the opening of the second accommodating cavity 122 facing the first accommodating cavity 121 is arc-shaped, the process of air flow entering the second accommodating cavity 122 from the first accommodating cavity 121 is smoother, the resistance is smaller, and the noise is smaller. The arc-shaped opening 1211 of the second accommodating cavity 122 can achieve a good flow guiding effect, and prevent wind noise generated by vortex of airflow in the flowing process.

Further, as shown in fig. 4 and 5, a semicircular arc member 142 is disposed at one end of the air guiding member 14 near the air outlet 112, and the arc convex surface of the semicircular arc member 142 is a wind striking surface.

Further, as shown in fig. 4, 5 and 6, the semicircular arc member 142 is located at the axial position of the second accommodating cavity 122, so that the air outlet 112 has a circular ring shape.

It should be noted that the annular air outlet 112 makes the airflow more uniform and smooth, and can effectively reduce the aerodynamic noise.

Specifically, the circular ring-shaped structure can increase the radiation angle of the air outlet 112, so that air flows more uniformly. In addition, when the air flows through the air outlet 112, the impact force and kinetic energy of the high-speed air can be dispersed due to the annular structure, so that the effect of reducing wind noise is achieved. Finally, the annular air outlet 112 also has higher aesthetic property, and can be coordinated with the decoration in the room to improve the overall decoration effect.

Further, a cavity 15 is formed between the outer casing 11 and the air duct 12.

Specifically, the air duct 12 is arranged inside the outer shell 11, and a connecting piece is arranged at the edge of the outer shell 11 and is fixedly connected with the air duct 12. And a relatively sealed structure is formed between the outer shell 11 and the air duct 12. In addition, a gap is maintained between the outer housing 11 and the barrel 12 except for the connection member, so that a cavity 15 is formed between the outer housing 11 and the barrel 12. While cavity 15 may block vibration and noise to some extent on barrel 12. Avoiding the vibration and noise on the air duct 12 from being directly transferred to the outer housing 11.

In summary, the present utility model provides a blower, in which the air flow in the second accommodating cavity 122 is uniformly dispersed on the sidewall by the air guiding member 14 and is ejected out through the annular air outlet 112. The airflow vortex in the second accommodating cavity 122 can be effectively reduced, and the effect of reducing noise is further achieved.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
