"Multiple" means greater than or equal to two.
[0032] like Figure 1 and Figure 2 As shown, a hair dryer head 1 provided by an embodiment of the utility model comprises a shell 11, a wind tube 12, a fan 13 and a hood 14; the shell 11 is a hollow structure, and an installation cavity is formed inside the shell 11; the wind tube 12 is arranged in the installation cavity, and the wind tube 12 is also a hollow structure, and an air cavity is formed inside the wind tube 12, and an air inlet 121 and an air outlet 122 which are connected to the air cavity are opened on the wind tube 12; the fan 13 is connected to the wind tube 12 and is located between the air inlet 121 and the air outlet 122, and the fan 13 is used to drive air to enter from the air inlet 121 and be discharged from the air outlet 122 after passing through the air cavity; the hood 14 is connected to the wind tube 12 and covers the air inlet 121; wherein, a plurality of wind grooves 141 are opened on the circumferential side wall of the hood 14, and the end faces of the hood 14 and the fan 13 opposite to the fan 13 are closed.
[0033] Specifically, Figure 2 As shown, the housing 11 is the outer shell of the hair dryer head 1, which is used to accommodate various components of the hair dryer head 1, including the wind tube 12. It can be understood that the housing 11 is not completely sealed, and an opening structure connected to the interior is usually provided on the housing 11. The opening structure of the housing 11 can be provided at a position adjacent to the air inlet 121 and the air outlet 122 on the wind tube 12, so as to allow the outside air to enter and the internal air to blow out, thereby realizing the function of blowing. In order to facilitate the use of the hair dryer head 1, a handle can also be provided on the housing 11 for picking up when in use, and the handle can also be connected to a structure such as a bracket to fix the hair dryer head 1 for use or place it in a designated position.
[0034] Specifically, Figure 2 As shown, the fan 13 is usually arranged in the air cavity of the air duct 12, and the input end of the fan 13 is located near the air inlet 121, and the output end is located near the air outlet 122, so as to drive the air to flow from the air inlet 121 to the air outlet 122. The fan 13 may specifically include a drive motor and a blade structure. When the power is turned on, the drive motor of the fan 13 drives the blades to rotate, and the blades drive the surrounding air to flow. Among them, the rotation axis of the fan 13 is as shown in FIG. Figure 2As shown by the dotted line, the air inlet 121 is opened in the direction of the axis, and the wind cover 14 covers the air inlet 121 along the axis. Therefore, when the fan 13 is started, the air needs to first pass through the wind slot 141 opened on the wind cover 14, and then flow into the air inlet 121. It is worth mentioning that the air outlet 122 of the wind tube 12 can be opened along the axis direction, or can be opened at a circumferential position of the wind tube 12 around the axis, such as Figure 2 As shown, when the air outlet 122 is opened at a circumferential position, the output end position of the fan 13 can be staggered, which has a certain blocking effect on the noise transmitted from the output end of the fan 13.
[0035] In the embodiment of the utility model, the wind groove 141 is opened on the circumferential side wall of the wind hood 14, specifically refers to the circumferential side wall of the wind hood 14 around the rotation axis of the fan 13, so that the air flows into and converges at the air inlet 121 from the side wall of the wind hood 14. In this process, the air first flows toward the rotation axis to pass through the wind groove 141, and then flows along the axial direction to enter the air inlet 121. Therefore, the air flow path is relatively tortuous. Compared with the design of sucking the outside air directly into the air inlet 121 along the axis, such a design can cause certain disturbances to the flow of air to slow down the air flow rate, thereby reducing the noise generated by the collision and friction between the air and the hair dryer components, and the side walls between the wind grooves 141 can also block a part of the noise generated by the fan 13. Moreover, the wind groove 141 is opened on the circumferential side wall of the wind cover 14, which increases the total air intake area of the fan 13, so that the fan 13 has a larger air intake volume, which is not only beneficial to the increase of the air output, but also improves the smoothness of the air intake of the fan 13. The air intake volume is guaranteed and it is also beneficial to reduce noise.
[0036] Furthermore, in the embodiment of the utility model, the wind hood 14 is closed at the end face opposite to the fan 13, specifically, the wind hood 14 is perpendicular to the rotation axis of the fan 13 and relatively far away from the end face of the fan 13. The end face is directly opposite to the input end of the fan 13 along the axis, and a considerable part of the noise generated by the operation of the fan 13 is directly transmitted to the end face along the axis. When the end face is closed, it can have a good blocking effect on this part of the noise. Compared with the method of directly opening the end face to allow the noise to be directly transmitted, this end face closed design can effectively block the noise from being directly transmitted, so that the hair dryer head 1 has a good noise reduction effect and improves the comfort of using the hair dryer.
[0037] The hair dryer head 1 provided by the embodiment of the utility model has a plurality of wind slots 141 on the circumferential side wall of the wind hood 14, and the end faces of the wind hood 14 and the fan 13 are closed. In this way, the plurality of wind slots 141 on the circumferential side wall increase the total air intake area, thereby increasing the air intake of the fan 13. The wind hood 14 and the fan 13 are closed, which changes the path of noise propagation, and avoids the noise generated during operation from being directly transmitted from the opening on the end face. At the same time, it also slows down the air flow rate, reduces the noise generated by the collision and friction between the air and the hair dryer components, and enables the noise generated by the fan 13 to be blocked by the closed end face of the wind hood 14 and the side wall surface between the wind slots 141, thereby effectively suppressing the propagation of noise and achieving a good noise reduction effect.
[0038] In some embodiments, such as Figure 2 As shown, each wind slot 141 extends in a direction parallel to the axis of the wind shield 14 and / or each wind slot 141 is arranged around the axis of the wind shield 14. Specifically, the axis of the wind shield 14 can be understood as Figure 2 As shown by the dotted line, the wind slot 141 extends in a direction parallel to the axis to form a long strip of slots. This design can reduce the space occupied by a single wind slot 141 in the circumferential direction. At the same time, the wind slot 141 is arranged around the axis of the wind cover 14, which can further increase the number of wind slots 141 opened within a limited space and increase the total area of the slots of the wind slot 141, thereby increasing the air intake to meet the air volume requirements of the hair dryer.
[0039] It is understandable that the wind slot 141 can extend in a direction parallel to the axis, or be arranged around the axis, which can increase the total area of the notch of the wind slot 141 and increase the air intake. Therefore, these two designs can be used simultaneously or separately.
[0040] In some embodiments, such as Figure 2 As shown, the wind hood 14 includes a first hood body 142 and a second hood body 143, the first hood body 142 is connected to the wind cylinder 12, one end of the second hood body 143 is connected to the first hood body 142, the end face of the other end opposite to the second hood body 143 is closed, and a plurality of wind grooves 141 are provided on the circumferential side walls of the first hood body 142 and / or the second hood body 143; wherein, along the direction perpendicular to the axis, the radial dimension of the first hood body 142 is greater than the radial dimension of the second hood body 143.
[0041] Specifically, the term "perpendicular to the axis direction" refers to a direction perpendicular to Figure 3In the direction of the dotted line shown, the size of the first cover body 142 is larger than the size of the second cover body 143, so that the wind shield 14 is stepped. This design can further disturb the air entering the wind shield 14, making the air flow more dispersed and uniform, and can also improve the overall structural strength of the wind shield 14 and reduce the difficulty of manufacturing the wind shield 14. In addition, in some embodiments, the wind shield 14 is detachable, and the smaller second cover body 143 is more convenient to grab during disassembly or installation, which facilitates the disassembly and assembly operations.
[0042] In some embodiments, such as Figure 3 As shown, a connecting groove 144 is provided on one end of the first cover body 142 connected to the wind tube 12, and one end of the wind tube 12 is inserted into the connecting groove 144; or a connecting groove is provided on one end of the wind tube 12 connected to the first cover body 142, and one end of the first cover body 142 is inserted into the connecting groove.
[0043] In the above embodiment, when the connection groove 144 is provided on the first cover body 142, the wind tube 12 is usually provided with a corresponding connection structure, such as a protrusion, an extension arm, etc., so that the wind tube 12 can be plugged into the connection groove 144. The same is true when the connection groove is provided on the wind tube 12. It can be understood that the above two design methods can achieve substantially the same technical effect, that is, to achieve a detachable connection between the first cover body 142 and the wind tube 12, so that the wind cover 14 can be removed from the wind tube 12 during maintenance.
[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, an elastic hook 123 is provided on the air duct 12 , and the elastic hook 123 is hung on the first cover 142 ; or an elastic hook is provided on the first cover 142 , and the elastic hook is hung on the air duct 12 .
[0045] Specifically, the elastic hook 123 may include an elastic arm extending toward the first cover body 142 and a protrusion disposed at the free end of the elastic arm. The elastic hook 123 allows the wind tube 12 and the first cover body 142 to approach to the installation position through the elastic deformation of the elastic arm, and then the elastic arm is reset so that the protrusion at the free end is buckled on the first cover body 142 to achieve a detachable connection between the wind tube 12 and the first cover body 142. It is understandable that the elastic hook 123 can be disposed on the wind tube 12 or on the first cover body 142, and both designs can achieve a detachable connection between the first cover body 142 and the wind tube 12.
[0046] In some embodiments, such as Figure 3As shown, an extension arm for forming a noise reduction groove 145 is provided on one end of the first cover body 142 connected to the wind cylinder 12, and a connecting groove 144 is provided on the extension arm; or an extension arm for forming a noise reduction groove is provided on one end of the wind cylinder 12 connected to the first cover body 142, and a connecting groove 144 is provided on the extension arm. Specifically, the noise reduction groove 145 is used to separate a certain distance between the first cover body 142 and the wind cylinder 12, wherein the extension arm for forming the noise reduction groove 145 is enclosed and sealed between the first cover body 142 and the wind cylinder 12. Through such a design, the noise reduction groove 145 can absorb and block part of the noise generated by the fan 13, thereby further reducing the impact of the noise.
[0047] In some embodiments, such as Figure 3 As shown, the wind shield 14 also includes a limit block 146, which is used to limit the installation position between the wind tube 12 and the shell 11, and the limit block 146 is arranged on the first cover body 142. Specifically, the limit block 146 is usually extended in a radial direction perpendicular to the axis of the wind shield 14, and realizes the limit function by abutting against the inner wall of the shell 11 along the radial direction, so that when the wind tube 12 is installed in the shell 11, the installation position of the wind tube 12 can be limited by the limit block 146 to prevent severe shaking, misalignment and other problems during use. The limit block 146 can also be made of a relatively soft material, so as to play a buffering role when abutting against the inner wall of the shell 11. Through the above design, the reliability of the connection of the wind tube 12 is improved.
[0048] In some embodiments, such as Figure 2 and Figure 3 As shown, the wind hood 14 also includes a suction nozzle 147, which is used to suck air to dissipate heat for the components adjacent to the suction nozzle 147. The suction nozzle 147 is arranged on the closed end face of the second cover body 143 and is located on the side away from the fan 13. Specifically, a channel is arranged inside the suction nozzle 147 to communicate with the inside of the wind hood 14, and the opening of the internal channel of the suction nozzle 147 is arranged toward the components in the hair dryer head 1 that need to dissipate heat. The components that need to dissipate heat usually refer to circuit boards, electronic components, etc. related to the functions of the hair dryer head 1. These components will generate heat when in use, causing their temperature to rise, and excessively high temperatures may cause hidden dangers such as damage to components or scalding users. Through the above design, when the fan 13 is started, due to the effect of the air pressure difference, the suction nozzle 147 can suck air from the outside of the wind hood 14 to the inside, driving the air flow around the components that need to dissipate heat near the suction nozzle 147, thereby playing a heat dissipation role for the nearby components.
[0049] In some embodiments, such as Figure 3As shown, the hair dryer head 1 also includes a heating component 15, which is connected to the wind tube 12 and is located in the wind cavity. Through the above design, the heating component 15 can heat the air in the wind tube 12, and combined with the function of the fan 13, the hair dryer head 1 can blow out hot air.
[0050] It can be understood that when the air outlet 122 of the air duct 12 is opened at Figure 2 When the air is in the circumferential position around the axis as shown, the air blown out from the output end of the fan 13 will not be blown out directly along the axis, but will be blown out from the side of the wind tube 12 after the flow direction changes in the wind tube 12. In this process, the air can fully contact with the heating component 15 to be heated. This design improves the efficiency of the heating component 15 in heating the air.
[0051] In some embodiments, such as Figure 2 As shown, the shell 11 is provided with an air inlet structure connected to the air inlet 121, and a noise reduction net 111 is connected to the air inlet structure. The noise reduction net 111 is a component with a mesh structure, and the mesh structure usually has a plurality of mesh holes opened at intervals for air to pass through, and the solid structure between the mesh holes can block part of the noise from being transmitted. Through the above design, the noise reduction net 111 can block the propagation of noise and further improve the noise reduction effect. At the same time, the noise reduction net 111 can also filter the air entering the shell 11, and can filter out impurities mixed in the air, thereby preventing external impurities from entering the air duct 12 and causing damage to internal parts.
[0052] like Figure 4 As shown, the embodiment of the utility model also provides a vertical hair dryer, including the above-mentioned hair dryer head 1 and a support rod 2 for supporting the hair dryer head 1, and the hair dryer head 1 is connected to the support rod 2. Specifically, when the hair dryer head 1 and the support rod 2 are combined to form a vertical hair dryer, it does not need to be used by hand, which can free the user's hands and provide a better user experience. Among them, the support rod 2 can also be set to be adjustable in height, and the relative angle between the hair dryer head 1 and the support rod 2 can also be set to be adjustable, so as to facilitate adjustment of the use position and / or storage. In addition, the hair dryer head 1 and the support rod 2 can rotate relative to each other, so as to adjust the air outlet direction of the hair dryer head 1, meet the use requirements at different angles, and enhance the user's use experience. And the vertical hair dryer, by adopting the above-mentioned hair dryer head 1, also has the advantages of large operating air volume, low operating noise, etc., and good comfort in use.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
