[0039] The implementation of the utility model is explained by specific embodiments below, and other advantages and effects of the utility model can be easily understood by those skilled in the art from the content disclosed in the specification.

[0040] It should be understood that the structure, proportion, size, etc. shown in the drawings attached to the specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limiting conditions of the implementation of the utility model, so they do not have technical substantive significance. Any modification of structure, change of proportion relationship or adjustment of size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "up", "down", "left", "right", "middle" and "one" in the specification are only for the convenience of clear understanding of the description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of the relative relationship, without substantial change of technical content, is also regarded as the scope of the implementation of the utility model.

[0041] In the related art, the hair dryer needs to be moved by the user to adjust the distance between the hair dryer and the target, so as to increase or reduce the blowing area. For example, when the user needs to blow the hair in a local area, the user needs to hold the hair dryer and make the air outlet of the hair dryer close to the hair, so that the air of the hair dryer acts on the hair in a local area with a smaller air outlet area. At the same time, when the user needs to blow the hair in a wide area, the user needs to hold the hair dryer and make the air outlet of the hair dryer away from the hair, so that the air of the hair dryer acts on the hair in a wide area with a larger air outlet area. The user needs to move the hair dryer back and forth to adjust the air outlet area of the hair dryer, which is very inconvenient. At the same time, due to the limitation of the length of the user's arm or the space around the user, it is also very inconvenient to adjust the relative position of the hair dryer and the hair.

[0042] Therefore, in view of Figures 1 to 17 , the present embodiment provides a hair dryer 10, which comprises a hair dryer body 11 having an air outlet assembly. The air outlet assembly comprises a first member and a second member, the second member is annularly arranged around the periphery of the first member and cooperates with the first member to form an air outlet gap 3, and part or all of the airflow of the hair dryer 10 is blown out from the air outlet gap 3.

[0043] In the present embodiment, as shown in Figures 3 to 6 , the first member has a first air outlet surface 8, and the second member has a second air outlet surface 9. The first air outlet surface 8 is the surface on the first member for affecting the blowing direction of the hair dryer, and the second air outlet surface 9 is the surface on the second member for affecting the blowing direction of the hair dryer. The first air outlet surface 8 and the second air outlet surface 9 form an air outlet gap 3, and the air of the hair dryer 10 can be blown out from the air outlet gap 3. The air outlet assembly is generally cylindrical, and its axial extension direction is the axis X, as shown in Figure 4 .

[0044] As an optional embodiment, the second air outlet surface 9 extends along the axis X of the air outlet assembly. At the same time, the first air outlet surface 8 comprises a first section a and a second section b located downstream of the first section a along the axis X. The first air outlet surface 8 cooperates with the second air outlet surface 9 to constrain and guide the air of the hair dryer 10 by using the Coanda Effect. In some specific embodiments, the diffusion state or convergence state of the air of the hair dryer 10 is mainly adjusted by the part of the first air outlet surface 8 corresponding to the second air outlet surface 9 by using the Coanda Effect, and the second air outlet surface 9 plays a cooperative role.

[0045] Specifically, the first section a can present an outward expanding shape in the air outlet direction, and the second section b presents an inward contracting shape in the air outlet direction, i.e., in the air outlet direction, the distance between the points on the first section a and the axis X gradually increases, and the distance between the points on the second section b and the axis X gradually decreases. The first member and the second member can be arranged to be relatively movable, for example, the first member can be moved relative to the second member between a first position and a second position, so as to adjust the relative position between the first member and the second member, and further adjust the shape of the air outlet gap 3 between the first member and the second member, and further adjust the air outlet direction of the hair dryer 10. In other words, as shown in Figure 9 、 Figure 10 When the first member is located at the second position, the second section b corresponds to the second air outlet surface 9, and the distance between the second section b and the second air outlet surface 9 in the air outlet direction gradually increases due to the inward contracting shape of the second section b, so that the air outlet direction of the hair dryer 10 is inwardly deflected due to the Coanda effect, Figure 9 、 Figure 10 The hollow arrow indicates the specific air outlet direction at the air outlet gap 3. At this time, the overall air outlet of the hair dryer 10 presents a converging state, and a smaller air outlet area can be formed to act on the local hair.

[0046] Meanwhile, as shown in Figure 11 、 Figure 12 When the first member is located at the first position, the first section a corresponds to the second air outlet surface 9, and in the air outlet direction, the distance between the first section a and the second air outlet surface 9 gradually decreases due to the outward expanding shape of the first section a, so that the air outlet direction of the hair dryer 10 is outwardly diffused due to the Coanda effect. Figure 11 、 Figure 12 The hollow arrow indicates the specific air outlet direction at the air outlet gap 3. At this time, the overall air outlet of the hair dryer 10 presents a diffusing state, and a larger air outlet area can be formed to act on a larger hair area. In this specific embodiment, the first position is the position of the first member when the first section a on the first member corresponds to the second air outlet surface 9 and cooperates with the second air outlet surface 9. Correspondingly, the second position is the position of the first member when the second section b on the first member corresponds to the second air outlet surface 9 and cooperates with the second air outlet surface 9.

[0047] The first section a and the second section b can not be fixedly arranged on the first air outlet surface 8, one of the first air outlet surface 8 and the second air outlet surface 9 is a cooperating air outlet surface extending along the air outlet direction of the air outlet assembly, and the other of the first air outlet surface 8 and the second air outlet surface 9 includes the first section a and the second section b. When the second air outlet surface 9 is the cooperating air outlet surface, the first section a and the second section b are located on the first air outlet surface 8, as shown in the above embodiment; when the first air outlet surface 8 is the cooperating air outlet surface, the first section a and the second section b are located on the second air outlet surface 9.

[0048] As shown in Figure 13 、 Figure 14As shown, in another specific embodiment, when the first air outlet surface 8 is a matching air outlet surface, the first segment a and the second segment b are located on the second air outlet surface 9, with the second segment b located downstream of the first segment a in the air outlet direction. The first segment a has an inward-curving shape, and the second segment b has an outward-expanding shape. In this specific embodiment, the diffusion or convergence state of the air outlet of the blower 10 is mainly adjusted by the portion of the second air outlet surface 9 corresponding to the first air outlet surface using the Coanda effect, while the first air outlet surface 8 plays a supporting role.

[0049] Specifically, the first segment a can be inwardly shaped in the air outlet direction, while the second segment b is outwardly shaped in the air outlet direction. The first and second components are relatively movable, meaning the first component can move between a first position and a second position relative to the second component. This allows adjustment of the relative position between the first and second components, thereby adjusting the shape of the air outlet gap 3 between them, and consequently, adjusting the air outlet direction of the blower 10. When the air outlet gap 3 primarily outlets inward, the overall air outlet of the blower 10 converges inward, exhibiting a converging state. Simultaneously, when the air outlet gap 3 primarily outlets outward, the overall air outlet of the blower 10 diffuses outward, exhibiting a diffused state. Figure 13 , Figure 14 In the diagram, the hollow arrow indicates the specific air outlet direction at air outlet gap 3.

[0050] In other words, such as Figure 13 As shown, when the first component is in the second position, the first segment a corresponds to the first air outlet surface 8. The distance between the first segment a and the first air outlet surface 8 in the air outlet direction gradually decreases due to the inward shape of the first segment a. Also based on the Coanda effect, the overall air outlet of the hair dryer 10 is in a converging state, which can form a smaller air outlet area to act on local hair.

[0051] like Figure 14 As shown, when the first component is in the first position, the second segment b corresponds to the first air outlet surface 8. The distance between the second segment b and the second air outlet surface 9 gradually increases due to the outward expansion shape of the second segment b. Also based on the Coanda effect, the overall air outlet of the hair dryer 10 presents a diffused state, which can form a larger air outlet area to act on a larger hair area.

[0052] In this embodiment, the first position and the second position are located on the extended axis X of the air outlet assembly, and the first position is located downstream of the second position on the axis X. The first component moves along the axis X.

[0053] As above Figures 9-14Both embodiments shown involve adjusting the airflow pattern of the hair dryer by moving the first component. Those skilled in the art will understand that, without any inventive effort, the airflow pattern can also be adjusted by moving the second component. This embodiment will not be described further in this application.

[0054] like Figures 1 to 11 As shown, in this embodiment, the second component is a blower duct 1. The blower duct 1 has an internal cavity for airflow. An air outlet 15 is provided at the front end of the blower duct 1, which communicates with the internal cavity of the blower duct 1. The gas inside the blower duct 1 is blown out through the air outlet 15, forming an airflow. The blower 10 typically includes a fan unit. The airflow generated by the fan unit passes through the internal cavity of the blower duct 1 and is finally blown out through the air outlet 15. The first component is the air guide 2, which is disposed inside the air outlet and cooperates with the blower duct 1 to form an air outlet gap 3, thereby constraining the airflow from the blower 10.

[0055] Accordingly, in this embodiment, the air guide body 2 can be a rotating body, and the air guide body 2 can be coaxially arranged with the air outlet 15 so that the air outlet gap 3 is a uniform annular shape, thereby enabling the air outlet of the blower 10 to be blown out evenly from the air outlet gap 3, which is beneficial to the uniform diffusion or contraction of the airflow of the blower 10.

[0056] like Figures 9-12 In the embodiment shown, the inner wall surface of the air outlet is the second air outlet surface 9, the air guide body 2 is spindle-shaped, and the first air outlet surface 8 is located on the outer periphery of the air guide body 2 and is part of the outer periphery surface of the air guide body 2.

[0057] In actual use of the hair dryer 10, when the first component moves to the first position, that is, when the first segment a of the first air outlet surface 8 mates with the second air outlet surface 9, the air outlet gap 3 of the hair dryer 10 is the gap between the second air outlet surface 9 and the first segment a. The distance between the first segment a and the second air outlet surface 9 gradually decreases due to the outward expansion shape of the first segment a, causing the air outlet direction of the hair dryer 10 to diffuse outward due to the Coanda effect. Figure 11 , Figure 12 The hollow arrow indicates the specific airflow direction at the air outlet gap 3. At this time, the overall airflow of the hair dryer 10 is diffused, which can create a larger airflow area that acts on a larger area of ​​hair.

[0058] When the first member moves to the second position, i.e. the second section b of the first air outlet surface 8 cooperates with the second air outlet surface 9, the air outlet gap 3 of the hair dryer 10 is the gap between the second air outlet surface 9 and the second section b. The distance between the second section b and the second air outlet surface 9 in the air outlet direction gradually increases due to the inwardly tapered shape of the second section b, so that the air outlet direction of the hair dryer 10 is inwardly deflected due to the Coanda effect. At this time, the overall air outlet of the hair dryer 10 presents a converging state, and a smaller air outlet area can be formed to act on the local hair.

[0059] In the embodiment, the first air outlet surface 8 and the second air outlet surface 9 can both be smooth curved surfaces, and the smooth transition between the first section a and the second section b is conducive to reducing the air outlet resistance of the hair dryer 10 and eliminating the air outlet noise of the hair dryer.

[0060] In the embodiment, the outward deflection along the axis X is defined as positive, and the inward deflection along the axis X is defined as negative. In the embodiment shown in FIG. 4, the extension direction of the first section a is defined as the first extension direction B, and the included angle between the first extension direction B and the axis X is 20°≤β≤40°, as shown in FIG. 5. Figures 9-12 Figure 11 In the embodiment shown in FIG. 4, the extension direction of the second section b is defined as the second extension direction A, and the included angle between the second extension direction A and the axis X is -40°≤α≤-20°, as shown in FIG. 6. Figure 9

[0061] The increase of the deflection amount of the first extension direction B relative to the axis X is conducive to increasing the diffusion degree of the air outlet of the hair dryer 10 and improving the diffusion effect of the air outlet, but if the deflection exceeds 40°, it will be too diffused to achieve the effect of rapid drying, and the airflow deflection angle will bring greater air resistance. If the deflection amount of the first extension direction B relative to the axis X is reduced to less than 20°, the diffusion effect will not be obvious enough. Therefore, the included angle between the first extension direction B and the axis X is set to be +20° to +40°, so that the hair dryer 10 has a better diffusion range while having lower air resistance. At the same time, if the deflection amount of the second extension direction A relative to the axis X is reduced to less than -40°, the air outlet airflow will converge too early to have a good blowing distance. If the deflection amount of the second extension direction A relative to the axis X is increased to more than -20°, the converging effect will not be obvious enough. Therefore, the included angle between the second extension direction A and the axis X is set to be -40° to -20°, so that the hair dryer 10 has a good converging effect while having a good air outlet distance.

[0062] Similarly, in the embodiment shown in FIG. 4, the included angle between the extension direction of the first section a and the axis X is set to be -40° to -20°, so that the hair dryer 10 has a good converging effect while having a good air outlet distance. The included angle between the extension direction of the second section b and the axis X is set to be 20° to 40°, so that the hair dryer 10 has a good diffusion range while having lower air resistance. Figures 13-14 ​​​

[0063] The air diffuser 10 has a low air resistance while having a good diffusion range.

[0064] As shown in Figure 7 , the air diffuser is provided with an inner recess 16 on the end face downstream of the air outlet direction, the inner recess 16 is recessed towards the inside of the air diffuser 10 along the axis X, that is, the recessed direction of the inner recess 16 is away from the air outlet direction of the air diffuser.

[0065] In the above embodiment, the air diffuser body is further provided with a moving assembly, the moving assembly is connected with the air diffuser to drive the air diffuser to move relative to the air duct. In some specific embodiments, the moving assembly can be a linear motor, a gear rack, etc. As shown in Figure 3 and Figure 8 , the moving assembly includes a screw rod 6, a screw sleeve 7 screwing with the screw rod 6, and a motor 5 fixed in the air duct, the screw rod 6 is arranged along the axis X of the air duct 1, the screw sleeve 7 is arranged on the air diffuser 2, and the motor 5 drives the air diffuser 2 to move along the axis X through the screw rod 6 and the screw sleeve 7.

[0066] In this embodiment, the air diffuser further includes a handle, the handle is connected to the air diffuser body and located below the air diffuser body, and the upper end of the front side of the handle is provided with a sensor for detecting the user condition.

[0067] Specifically, as shown in Figure 1 , Figure 2 , in this embodiment, the upper end of the handle 12 towards the side of the air outlet 3 of the air duct 1 is provided with a sensor 14 for detecting the user condition. The sensor 14 can be selected from different types of sensors to detect different condition information of the user, such as the position of the user's hair, the distance between the user's hair and the air diffuser, the type of the user's hair, the humidity of the user's hair, the temperature of the user's hair, etc.

[0068] In this embodiment, the air diffuser further includes a controller, the controller is connected with the sensor 14 and the moving assembly, the controller controls the moving assembly by analyzing the information detected by the sensor 14, so as to adjust the convergence degree or diffusion degree of the air outlet of the air diffuser, for example, when the user's head is close, the diffusion degree of the air outlet is increased to increase the area of the air blowing to the user's head; when the user's head is far away, the convergence degree of the air outlet is increased to ensure the efficiency of the air blowing and drying.

[0069] As shown in Figures 15 to 17As shown, in the embodiment, a hair dryer system is also provided, which comprises the hair dryer as described above, and further comprises a base station 20, which is provided with a mounting seat 21 for placing or holding the hair dryer. The user can place or hold the hair dryer on the mounting seat 21, which is simple and convenient. The base station 20 can be installed on a wall in a house, and there is no need to hold the hair dryer, which liberates the hands of the user. Meanwhile, the controller can be arranged in the base station 20 and is in communication connection with the hair dryer through a cable or a wireless signal, which reduces the weight of the hair dryer. The base station 20 can use external power supply, which is stable, and reduces the energy storage unit such as a battery, thereby reducing the weight of the product.

[0070] As shown in the embodiment, Figure 16 , Figure 17 In the embodiment, the base station 20 is provided with a lifting assembly 22, and the mounting seat 21 is arranged on the lifting assembly 22. The lifting assembly can drive the mounting seat 21 to move up and down, so as to meet the different height requirements of the user for the hair dryer. The controller is connected with the lifting assembly and controls the lifting of the mounting seat 21. The controller can adjust the height of the hair dryer according to the user lifting information collected by the sensor 14, so that the hair dryer can blow more to the hair of the user, and the air outlet effect is improved. The mounting seat 21 can also rotate relative to the lifting assembly, so that the hair dryer rotates relative to the lifting assembly at a certain height, so that the air outlet of the hair dryer has a larger action area.

[0071] As shown in the embodiment, Figure 16 , Figure 17 In some specific embodiments, the lifting assembly comprises a lead screw and a light rod which are parallel to each other. The lead screw and the light rod are arranged along the lifting direction of the mounting seat 21. The mounting seat 21 is sleeved on the lead screw and the light rod, and the mounting seat 21 moves up and down through the lead screw and the light rod. In the embodiment, the base station 20 comprises a rudder and a speed reduction mechanism, which are used in cooperation with the lead screw to drive the mounting seat 21 to move up and down. The light rod is used in cooperation with the lead screw, which can ensure the stable lifting of the mounting seat.

[0072] In the embodiment, the hair dryer is connected with the base station 20 through the wire 13. The cable connection has the advantages of reliable connection and high stability. The base station 20 is provided with a wire collector 23 for collecting the wire 13. The wire collector 23 can store the wire 13 in the wire collector 23, which reduces the space occupied by the wire 13 and is beneficial to improve the neatness of the hair dryer. In some specific embodiments, the wire collector 23 can be an automatic wire collector, which can automatically adjust the length of the wire 13 in time according to the use of the user, so as to avoid the winding and knotting of the wire 13. In another specific embodiment, the wire collector 23 can also be a manual wire collector, which can simplify the hair dryer system and reduce the cost of the product.
