[0001] The present invention relates to the technical field of hair styling products, and more particularly to a hair styling device. Background Art

[0002] The hairdressing device in the prior art generally includes a heating plate, an air duct and a motor fan for providing air blowing. The air generated by the motor fan needs to travel a certain distance before entering the air duct. In existing products, the motor fan is generally arranged inside the shell, and the air generated by the motor fan flows directly into the air duct inside the shell. Since the sealing effect of the shell is not very good and there are gaps, the air generated by the motor fan is likely to leak out through the gaps, reducing the wind force in the air duct. In addition, since other components are arranged inside the shell, the surface of the space inside the shell for the air generated by the motor fan to pass through is uneven, and the air encounters greater resistance during the flow process.

[0003] In summary, how to reduce the resistance encountered by the air blown by the motor fan during the flow process is an urgent problem to be solved by those skilled in the art. Summary of the Invention

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The core of the present invention is to provide a hairdressing device, which can make the air generated by the motor fan enter through the air inlet of the air duct connector and enter the air duct through the air outlet of the air duct connector, thereby reducing the kinetic energy loss of the air during the flow process.

[0035] Please refer to Figure 1-5 , Figure 1 This is a structural diagram of a specific embodiment 1 of the air duct connector provided by the present invention; Figure 2 This is a structural diagram of a motor fan installed in an air duct connector; Figure 3 This is a structural diagram of the motor fan installed outside the air duct connector; Figure 4 This is a structural diagram of a specific embodiment 2 of the air duct connector provided by the present invention; Figure 5 This is an exploded schematic diagram of the hairdressing device provided by the present invention.

[0036] The hairdressing device provided in this specific embodiment includes: an upper air duct, a lower air duct, a heating plate, a handle housing, and a motor fan 2 for providing air. The handle housing is provided with an air duct connector 1 for allowing the air to pass through. The air duct connector 1 includes an air inlet 13 for allowing the air generated by the motor fan 2 to enter, an upper air outlet 11 for communicating with the air inlet of the upper air duct, and a lower air outlet 12 for communicating with the air inlet of the lower air duct. The upper air outlet 11 and the lower air outlet 12 are symmetrically arranged about the middle cross-section of the air duct connector 1. The inner surface of the air duct connector 1 is a smooth surface. The air enters through the air inlet 13 and is blown out through the upper air outlet 11 and the lower air outlet 12.

[0037] Preferably, the upper air duct can be set in the upper air duct shell 21, the lower air duct can be set in the lower air duct shell 22, and the heating plate can be set outside the upper air duct shell 21 and the lower air duct shell 22 to avoid the blowing air affecting the temperature of the heating plate, and also to avoid the heating plate heating the blowing air.

[0038] It should be noted that the upper air outlet 11 and the lower air outlet 12 are collectively referred to as air outlets, and the upper air duct housing 21 and the lower air duct housing 22 are collectively referred to as air duct housings.

[0039] Preferably, the air inlet 13 and the air outlet can be respectively arranged at the two ends of the length direction of the air duct connector 1. Of course, the air inlet 13 and the air outlet can also be arranged at other positions of the air duct connector 1, which is determined according to actual conditions and will not be elaborated here.

[0040] During use, the air generated by the motor fan 2 can enter through the air inlet 13 of the air duct connector 1, pass through the inside of the air duct connector 1, and be blown out through the air outlet. Since the inner surface of the air duct connector 1 is smooth, the air encounters less resistance inside the air duct connector 1.

[0041] Compared with the prior art, the hairdressing device provided by the present invention can prevent the blown air generated by the motor fan 2 from encountering greater resistance in the process of flowing to the inlet of the air duct housing, thereby reducing the kinetic energy loss of the blown air and ensuring the wind force of the blown air entering the air duct housing. In addition, due to the provision of the air duct connector 1, the blown air can be prevented from leaking through the gaps in the hairdressing device housing, thereby ensuring that a sufficient flow of blown air enters the air duct housing, thereby improving the hairdressing effect.

[0042] Since the air duct connector 1 needs to be isolated from other components during the setting process, and the shapes and setting positions of other components are not uniform, in order to facilitate installation and processing, the air duct connector 1 can be set as a duct connector made of soft rubber material, so that the air duct connector 1 has a certain deformation during the installation process.

[0043] Preferably, the air duct connector 1 is made of silicone material.

[0044] The motor fan 2 can be installed inside the air duct connector 1, or it can be set on the end face of the air inlet 13 of the air duct connector 1. An installation portion for installing the motor fan 2 can be set on the air inlet end face of the air duct connector 1 or on the air inlet side inside the air duct connector 1.

[0045] When the motor fan 2 is installed inside the air duct connector 1, the overall space occupied by the air duct connector 1 and the motor fan 2 can be appropriately reduced, so that the product can be miniaturized.

[0046] On the basis of the above embodiment, the air outlet can include an upper air outlet 11 and a lower air outlet 12, and the upper air outlet 11 and the lower air outlet 12 are both connected to the air duct shell. When the air duct shell includes an upper air duct shell 21 and a lower air duct shell 22, the upper air outlet 11 is used to communicate with the upper air duct shell 21, and the lower air outlet 12 is used to communicate with the lower air duct shell 22, and the upper air outlet 11 and the lower air outlet 12 are symmetrically arranged about the middle section of the air duct connector 1.

[0047] It should be noted that the middle section of the air duct connector 1 is as follows: Figure 2 In the direction shown, it is the middle symmetrical cross-section of the air duct connector 1 in the horizontal direction.

[0048] The upper air outlet 11 and the upper air duct shell 21, and the lower air outlet 12 and the lower air duct shell 22 can be plug-in connections or other connection methods. When it is a plug-in connection, preferably, the air inlet of the upper air duct shell 21 is mounted on the outer periphery of the upper air outlet 11, and the air inlet of the lower air duct shell 22 is mounted on the outer periphery of the lower air outlet 12, and the upper air duct shell 21 and the upper air outlet 11 are sealed, and the lower air duct shell 22 and the lower air outlet 12 are sealed.

[0049] The upper air outlet 11 and the lower air outlet 12 are symmetrically arranged about the middle section of the air duct connector 1, so that the air volume entering the upper air duct shell 21 is the same as the air volume entering the lower air duct shell 22, so that the hair is evenly blown and the cooling and styling time is shortened.

[0050] On the basis of the above embodiment, a diverter surface 1021 for diverting the blowing air into the upper air outlet 11 and the lower air outlet 12 may be provided inside the air duct connector 1 .

[0051] Preferably, the diverter surface 1021 is symmetrically arranged with respect to the middle cross section of the air duct connector 1 so as to divert the blowing air evenly.

[0052] On the basis of the above embodiment, the diverter surface 1021 can be a circular arc surface symmetrically arranged about the middle cross section of the air duct connector 1; Figure 2 、 Figure 3 As shown, the diverter surface 1021 is symmetrically arranged about the middle section of the air duct connector 1. When the wind flows forward in the air duct connector 1, it encounters the diverter surface 1021 and is diverted along the arc surface. The wind after diversion is blown out from the upper air outlet 11 and the lower air outlet 12 respectively.

[0053] Or the diversion surface 1021 is a slope symmetrically arranged about the middle section of the air duct connector 1, and the slope includes two slope units symmetrically arranged about the middle section of the air duct connector 1, and the connection between the two slope units forms an angle. When the wind flows forward in the air duct connector 1, it encounters the angle of the slope connection and is diverted along the symmetrically arranged slope. The wind after diversion is blown out from the upper air outlet 11 and the lower air outlet 12 respectively.

[0054] Or the diversion surface 1021 is a combination of an arc surface and an inclined surface symmetrically arranged about the middle section of the air duct connector 1; the inclined surface includes two inclined surface units symmetrically arranged about the middle section of the air duct connector 1, and the connection between the two inclined surface units is smoothly transitioned through the arc surface. When the blown air flows forward in the air duct connector 1, it encounters the transition arc surface at the inclined surface connection and is diverted along the symmetrically arranged inclined surface. The blown air after diversion is blown out from the upper air outlet 11 and the lower air outlet 12 respectively.

[0055] Or the diversion surface 1021 is a combination surface of a plane and an inclined surface symmetrically arranged about the middle section of the air duct connector 1, and the inclined surface includes two inclined surface units symmetrically arranged about the middle section of the air duct connector 1, and the connection between the two inclined surface units is a vertically arranged plane. When the blown air flows forward in the air duct connector 1, it encounters the vertical plane at the inclined surface connection and is diverted along the symmetrically arranged inclined surface. The blown air after diversion is blown out from the upper air outlet 11 and the lower air outlet 12 respectively.

[0056] like Figure 2 As shown, the angle B is the angle between the diverter surface 1021 in the diverter section 102 and the outer ring shell. In order to allow the air to be blown out smoothly from the air outlet and to ensure the flow rate and flow of the air, the size of the angle B can be reasonably designed according to actual conditions, which will not be elaborated here.

[0057] Of course, the number of air outlets can be greater than 2, and the shape of the diverter surface 1021 can also be other structures that meet the requirements. The specific shape is determined according to the actual situation and will not be elaborated here.

[0058] On the basis of the above embodiment, the air duct connector 1 may include a cylindrical section 101 and a diverter section 102 for blowing air out from the upper air outlet 11 and the lower air outlet 12 .

[0059] During use, after the blowing air enters from the air inlet 13, it passes through the cylindrical section 101 and enters the diversion section 102. Since the outer ring size of the outlet of the diversion section 102 is smaller than the outer ring size of the cylindrical section 101, the total area of ​​the air outlet is smaller than the total area of ​​the air inlet 13, so the air outlet area of ​​the blowing air can be made smaller than the area of ​​the air inlet 13. When the blowing flow rate remains unchanged, the pressure on the air outlet side can be increased to increase the wind speed.

[0060] On the basis of the above embodiment, an upper air outlet section for blowing air out from the upper air outlet 11 and a lower air outlet section for blowing air out from the lower air outlet 12 may be provided in the diversion section 102;

[0061] The upper air outlet section and the lower air outlet section are both tapered structures with the inlet size larger than the outlet size.

[0062] The setting of the tapered structure can reduce the air outlet area of ​​the blowing air compared to the area of ​​the air inlet 13, and can increase the wind speed while keeping the air flow rate unchanged.

[0063] On the basis of the above embodiment, the upper air outlet 11 and the lower air outlet 12 may both be arc-shaped structures.

[0064] Preferably, both ends of the arc-shaped structure are bent toward the middle cross-section of the air duct connector 1 .

[0065] The bending setting makes the shape of the upper air outlet 11 consistent with the shape of the air inlet of the upper air duct shell 21, and the shape of the lower air outlet 12 consistent with the shape of the air inlet of the lower air duct shell 22, which is beneficial to the setting of the air outlet in the upper air duct shell 21 and the air outlet in the lower air duct shell 22.

[0066] Preferably, the heating plate may include an upper heating plate 41 and a lower heating plate 42 that are arranged opposite to each other, and the gap between the upper heating plate is set at the lower part of the upper air duct shell 21 , and the gap between the lower heating plate 42 is set at the upper part of the lower air duct shell 22 .

[0067] In order to make the hairdressing device suitable for both left-handed and right-handed holding, upper air duct outlets can be provided on both sides of the width direction of the lower surface of the upper air duct housing 21, and lower air duct outlets can be provided on both sides of the width direction of the upper surface of the lower air duct housing 22.

[0068] like Figure 5 As shown, the hair styling device includes a handle 5 and a styling structure. The handle 5 includes a handle shell and a circuit board 52 structure arranged inside the handle shell. The handle shell is connected to the power cord and is provided with a switch button 51. The styling structure includes an upper heating plate 41, a lower heating plate 42, an upper air duct shell 21 and a lower air duct shell 22. The upper heating plate 41 is installed on the upper air duct shell 21 through an upper heating plate mounting member 411, and the lower heating plate 42 is installed on the lower air duct shell 22 through a lower heating plate mounting member 421. A finger buckle 3 is provided between the styling structure and the handle 5. By bending the finger buckle 3, the upper heating plate 41 can be opened or closed relative to the lower heating plate 42.

[0069] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other. Any combination of all the embodiments provided by the present invention is within the scope of protection of this invention and will not be described in detail here.

[0070] The above describes the hair styling device provided by the present invention in detail. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The above examples are merely intended to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will readily appreciate that various improvements and modifications may be made to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims.
