Description

Technical Field

[0001] The utility model relates to the technical field of air nozzles, in particular to a rotating air nozzle and a hair dryer. Background Art

[0002] Hair dryers are mainly used for drying and shaping hair, and are a must-have small appliance in people's daily lives. A hair dryer is a tool composed of a set of electric heating wires and a small fan, used for drying and styling hair. When powered on, the electric heating wires will generate heat, and the wind blown out by the fan will become hot air after passing through the electric heating wires; if only the small fan rotates and the electric heating wires are not hot, then the wind blown out is cold air instead of hot air. As people's pace of life continues to accelerate, people hope to shorten the time they spend on self-care as much as possible, in order to meet people's needs.

[0003] Today's hair dryers are designed with high power, high wind speed and high temperature, and are equipped with wind-converging nozzles to achieve higher wind speed and wind temperature to shorten hairdressing time. However, the high-temperature airflow will make users feel that it is very hot when blowing on the scalp, and it is concentrated in the same direction, which can easily cause moisture loss, heat damage, damage to the hair, and even the scalp. Therefore, users need to constantly swing the hair dryer to keep the high-temperature airflow blowing on the scalp moving. This operation method will make users very laborious when using it, and the user experience is limited.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0009] The beneficial effect of the rotary air nozzle provided by the present application is that: compared with the prior art, by setting a grid-shaped impeller disk, at least the first impeller or the second impeller of the impeller disk is tilted, and when the airflow passes through the impeller disk, the wind flow acts on the impeller disk to rotate and switch different blowing areas. On the one hand, the contact area can be increased by means of the first impeller and the second impeller that are tilted, thereby strengthening the interaction of forces between the impeller disk and the airflow and enhancing the air outlet effect; on the other hand, the first impeller and the second impeller that are tilted can make the impeller disk rotate, so that the airflow direction is tilted and offset according to the first impeller and the second impeller, and then the airflow is rotationally offset, thereby realizing continuous switching of the blowing area and achieving the effect of intermittent air outlet, so that the user can avoid the problem of hot air being concentrated in one direction when blowing hair, and the user does not need to swing the hair dryer constantly, thereby reducing the user's operating difficulty and saving more effort, thereby improving the user's use experience.

[0034] Please also read Figures 1 to 6 The rotary air nozzle provided in the embodiment of the present application is now described. The rotary air nozzle 10 comprises: a base 11 and a fan blade disc 12 .

[0035] The fan blade disk 12 can be rotatably installed on the base 11; the fan blade disk 12 is arranged in a grid shape, forming a plurality of first fan blades 121 and a plurality of second fan blades 122, and at least one first fan blade 121 and / or at least one second fan blade 122 are arranged at an angle; when the air flow passes through the fan blade disk 12, the air flow causes the fan blade disk 12 to rotate and switch different blowing areas.

[0036] Specifically, by setting a grid-shaped impeller 12, at least the first impeller 121 or the second impeller 122 of the impeller 12 is tilted, when the airflow passes through the impeller 12, the airflow causes the impeller 12 to rotate and switch different blowing areas.

[0037] First embodiment

[0038] Please also read Figures 1 to 6 The rotating air nozzle 10 provided in the first embodiment of the present application includes a base 11 and a fan blade disc 12 .

[0039] The base 11 is hollow and has an air outlet chamber 111. The upper surface of the base 11 is provided with a first air inlet 112 communicating with the air outlet chamber 111, and the lower surface of the base 11 is provided with a first air outlet 113 communicating with the air outlet chamber 111. The first air inlet 112 is used for inserting the air outlet end of the hair dryer, and then the air flow blown by the hair dryer passes through the air outlet chamber 111 and is blown out to the first air outlet 113.

[0040] Specifically, the bracket 114 is installed inside the air outlet chamber 111, and the cross-section of the air outlet chamber 111 is circular. After the first rotating shaft 115 is installed on the bracket 114, it coincides with the center of the air outlet chamber 111; the cross-section of the fan disc 12 is also circular, and one end of the first rotating shaft 115 is connected to the center position of the fan disc 12 so that the fan disc 12 can be rotatably set at the position of the air outlet chamber 111.

[0041] Preferably, the base 11 is installed with a bracket 114 , the bracket 114 is rotatably installed with a first rotating shaft 115 , and the fan disc 12 is fixedly installed on the first rotating shaft 115 .

[0042] Exemplarily, a first axial hole 1141 is provided at the center position of the bracket 114, one end of the first rotating shaft 115 is integrally formed with a surface of the impeller disk 12, and the other end of the first rotating shaft 115 is inserted upward from the lower end of the first axial hole 1141, so that the other end of the first rotating shaft 115 is exposed to the upper end of the first axial hole 1141, and the first rotating shaft 115 can be rotatable in the first axial hole 1141; the other end of the first rotating shaft is threadedly connected with a first screw 1142, and the first screw 1142 has a first limiting plate 1143, and the first limiting plate 1143 abuts against the upper surface of the bracket 114 to limit the first rotating shaft 115 from separating from the first axial hole 1141.

[0043] In the first embodiment of the present application, there are at least two first fan blades 121, and the two first fan blades 121 are spaced apart from left to right; there are at least two second fan blades 122, and the two second fan blades 122 are spaced apart from front to back, and each first fan blade 121 is connected to each second fan blade 122 to form a grid structure.

[0044] Specifically, among each first fan blade 121 and each second fan blade 122, at least one first fan blade 121 is arranged tilted; by arranging at least one tilted fan blade, the wind flow can act on the fan blade disk 12 to rotate, so that the blowing area is constantly changed, thereby achieving the effect of intermittent wind output; at the same time, due to the use of tilted fan blades, the contact area between the airflow and the fan blade disk 12 is increased, the interaction of forces between the fan blade disk 12 and the airflow is intensified, and the effect of intermittent wind output is increased.

[0045] In more detail, the intermittent air outlet effect can be achieved by adjusting the inclination angle of the first fan blade 121 or the second fan blade 122, changing the contact area between the airflow and the fan blade disk 12, and the magnitude of the component force in the centripetal force direction, so as to achieve intermittent air outlet effects of different intensities. After testing, when both the first fan blade 121 and the second fan blade 122 are inclined, the intermittent air outlet effect is most obvious, and at the same time, the inclination angle of the fan blade can be ensured to be small. Multiple first fan blades 121 are arranged at intervals from left to right, and multiple second fan blades 122 are arranged at intervals from front to back. The first fan blade 121 is arranged vertically relative to the second fan blade 122; or, the first fan blade 121 is arranged at an inclination relative to the second fan blade 122; therefore, the inclination angles of the first fan blade 121 and the second fan blade 122 can be set according to actual needs.

[0046] Second embodiment

[0047] The specific structure of the second embodiment is substantially the same as that of the first embodiment, except that the first fan blade 121 and the second fan blade 122 are arranged in another structure.

[0048] In the second embodiment of the present application, multiple first fan blades 121 have at least one inclined setting, and multiple second fan blades 122 have at least one inclined setting; the first fan blades 121 extend from top to bottom, and the first fan blades 121 are inclined at one end close to the first air outlet 113; the second fan blades 122 extend from top to bottom, and the second fan blades 122 are inclined at one end close to the first air outlet 113.

[0049] Preferably, the angles of the inclined first fan blade 121 and the inclined second fan blade 122 may be the same or different; however, the inclination directions thereof are the same.

[0050] Exemplarily, the first fan blade 121 is arranged to be inclined from top to bottom and to the left, and the second fan blade 122 is arranged to be inclined from top to bottom and to the left.

[0051] It should be noted that in the first embodiment and the second embodiment of the present application, the first fan blade 121 and the second fan blade 122 can be arranged to be inclined or not inclined according to actual needs.

[0052] For example, only one first fan blade 121 is tilted, and the other first fan blades 121 and all the second fan blades 122 are not tilted. The fan disk 12 can also be rotated using one tilted first fan blade 121, so that the blowing area is constantly changed, thereby achieving the effect of intermittent air output.

[0053] Of course, by providing a plurality of inclined first blades 121 and a plurality of inclined second blades 122, since the mesh inner blades will intersect, in the same state, the staggered first and second blades 122 can give different directions of force to the airflow, increase the offset effect, and thus enhance the intermittent air discharge effect. Therefore, different inclination numbers and inclination angles of the first blades 121 and the second blades 122 can be selected according to actual needs to achieve different degrees of intermittent air discharge effects.

[0054] Third embodiment

[0055] The third embodiment of the present application is a specific application of the rotating air nozzle 10, including the rotating air nozzle 10 and a hair dryer.

[0056] When installing the rotating air nozzle 10, align the first air inlet 112 with the air outlet of the hair dryer, and then insert the hair dryer into the first air inlet 112, so that the air flow blown by the hair dryer can be blown out to the first air outlet 113 through the blowing chamber. At this time, the air flow will flow through the impeller disk 12, and then cause the impeller disk 12 to rotate, so that the blowing area is constantly changed, thereby achieving the effect of intermittent air outlet; during the process of blowing the hair, the user can avoid the problem of hot air being concentrated in one direction, and the user does not need to swing the hair dryer constantly, thereby reducing the user's operating difficulty and saving more effort, thereby improving the user's sense of experience.

[0057] Preferably, a plurality of first snap-fit ​​grooves 116 are provided on the outer side surface of the base 11 near the first air inlet 112, and the plurality of first snap-fit ​​grooves 116 are arranged in a circular array with equal spacing; the plurality of first snap-fit ​​grooves 116 can be adapted to the snap-fit ​​protrusions on the inner side of the air outlet of the hair dryer, so that the entire rotating air nozzle 10 can be rotated and snapped into the air outlet of the hair dryer for use.

[0058] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
