[0020] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0021] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0022] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] In the related art, the button design of traditional stylers often has drawbacks such as unclear function labels and overly compact or scattered button layouts, which makes it inconvenient for users to operate with one hand, affecting the user experience. In addition, the heating unit in traditional stylers has a high temperature when working. If it is too close to the PCBA board, buttons and corresponding housing, it is easy to cause aging of the corresponding components.

[0024] The present application provides a hair styling tool, which optimizes its main structure, designs one end of the outer shell of the handle part as a gradually expanding connection port, and cooperates with the annular adapter cover to form an accommodating cavity, thereby forming an accommodating cavity with an annular boss, and then integrates a button assembly onto the annular boss, thereby achieving an optimized arrangement of the button assembly, allowing the user to operate it with one hand, improving efficiency, and enhancing the fluency of human-computer interaction.

[0025] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and implementation methods can be combined with each other if there is no conflict.

[0026] In an exemplary embodiment of the present invention, a hair styling tool is provided. Figure 1 As shown, Figure 1 1 is a schematic diagram of the main structure of a hair styling tool according to an exemplary embodiment. The hair styling tool comprises: a main structure 10 and a styling attachment (not shown in the figure) detachably connected to the main structure 10, wherein the styling attachment comprises at least one of a nozzle, a curling rod and a comb assembly. The main structure 10 comprises: a handle portion 101 and a ring-shaped adapter cover 102.

[0027] like Figure 1-Figure 2 As shown, the handle portion 101 includes a housing 1011, the housing 1011 is a cylindrical structure and an air supply unit 104 is disposed inside the housing 1011, and a gradually expanding connection port 10111 is formed at the first end of the housing 1011. A power cord can be disposed at the second end of the housing 1011, and the internal air supply unit 104, the heating unit 105 and the circuits of the corresponding electrical components can be connected to the power cord and led out from the second end.

[0028] like Figure 1-Figure 2 As shown, the annular adapter cover 102 is covered on the connection port 10111 and cooperates with the shell 1011 to form a receiving cavity. A heating unit 105 is arranged in the receiving cavity. Since the shell 1011 is a cylindrical structure, most of the cavity structure of the receiving cavity is formed by the shell 1011 part. At this time, the air supply unit 104 can be arranged upstream of the shell 1011 and corresponding to the corresponding air inlet hole, that is, on the side close to the second end. In order to integrate the key assembly and prevent the PCBA board 107 and other devices from being affected by the high temperature of the heating unit 105, the structure of the annular adapter cover 102 can be optimized, that is, the connection between the annular adapter cover 102 and the shell 1011 protrudes outward along its radial direction to form an annular boss, and the button assembly is arranged on the annular boss. The middle area of ​​the annular adapter cover 102 protrudes to the side away from the shell 1011 to form a transfer part 1021, and the transfer part 1021 is used to connect the modeling accessories.

[0029] In this exemplary embodiment, the button assembly of a hair styling tool (such as a hair dryer, a curling iron, etc.) is adjusted to an annular boss formed by the shell 1011 and the annular adapter cover 102, and the annular boss is radially extended outward to form a flying saucer-like structure. After the button assembly is integrated on the annular boss, when the user holds the shell 1011 of the handle 101, the user can control the button assembly with one hand through the index finger or thumb to switch the function gears such as wind speed, wind temperature and mode. Based on this hair styling tool, the user can operate it with one hand, which greatly improves the operation efficiency and enhances the smoothness of human-computer interaction.

[0030] In addition, since the handle 101 is provided with a fan unit and a heating unit 105, the heating unit 105 is located downstream of the air supply unit 104 and corresponds to the annular boss, the annular adapter cover 102 can be made of a heat-resistant material, and the housing 1011 can also be made of a heat-resistant material if the cost is not considered. In this embodiment, the annular boss formed by the housing 1011 and the annular adapter cover 102 can increase the heat dissipation space, reduce the internal loss of the machine, and increase the service life of the hair styling tool. At the same time, it can also prevent heat from being directly transferred to the user's hand through the handle, thereby improving the user's comfort.

[0031] It should be noted that, in addition to the above-mentioned annular boss formed by the annular adapter cover 102 and the housing 1011, the connection port 10111 can also be separated from the housing 1011, that is, the annular boss is formed by the upper cover and the lower cover, and the lower cover is detachably connected to the housing 1011. In this case, the upper cover is the annular adapter cover 102, and the lower cover corresponds to the connection port 10111. After the corresponding components are assembled inside the annular boss, it is connected to the housing 1011 through the lower cover. In this case, the accommodating cavity is formed by the annular adapter cover 102, the lower cover and the housing 1011.

[0032] In some exemplary embodiments, Figure 2-Figure 3 As shown, in this exemplary embodiment, the main structure 10 also includes a PCBA board 107 and a bracket assembly. The PCBA board 107 is arranged in the accommodating cavity. The bracket assembly is used to fix the PCBA board 107 and the heating unit 105. Furthermore, the accommodating cavity includes a first cavity and a second cavity arranged circumferentially around the first cavity, the heating unit 105 and the air supply unit 104 are arranged in the first cavity, the PCBA board is arranged in the second cavity, and the first cavity and the second cavity are isolated. An air flow inlet connected to the first cavity is provided on the housing 1011, and the external air flow enters the first cavity from the air flow inlet, and flows through the fan unit 104 and the heating unit 105 in sequence. Since the first cavity and the second cavity are isolated, the air flow of the first cavity will not enter the second cavity, thereby avoiding the influence of the hot air flow and the heat radiation of the heating unit on the working performance of the PCBA board 107.

[0033] In this embodiment, in order to reduce the size of the main structure 10 as much as possible, the PCBA board 107 can also be made into an annular plate structure and mounted on the outer peripheral side of the heating unit 105. Since the PCBA board 107 is located at the position of the annular boss, there is enough installation space to assemble it.

[0034] In order to ensure the stability of fixing each component in the installation cavity, multiple bracket plates can be provided to cooperate with each other to fix the PCBA board 107 and the heating unit 105 and other devices. Optionally, the bracket assembly includes a first bracket plate 1012 and a second bracket plate 1013. The first bracket plate 1012 is arranged in the accommodating cavity for installing the heating unit 105. The second bracket plate 1013 is arranged at the first end of the housing 1011, and the PCBA board 107 is fixed between the first bracket plate 1012 and the second bracket plate 1013 by the cooperation of the second bracket plate 1013 and the first bracket plate 1012. Further, two first positioning columns 10133 are also provided on the second bracket plate 1013, and the PCBA board 107 is provided with corresponding first positioning holes 1073, which is convenient for improving assembly efficiency.

[0035] In some exemplary embodiments, Figure 2-Figure 3 As shown, in this exemplary embodiment, in order to protect the connection between the annular adapter cover 102 and the shell 1011, an appearance protection piece can also be added at the corresponding position. Exemplarily, the main structure 10 also includes an outer ring connector 106. The outer ring connector 106 is sleeved on the outer peripheral side of the connection between the annular adapter cover 102 and the shell 1011, and is used to protect the shell 1011 and the annular adapter cover 102.

[0036] In some exemplary embodiments, Figure 1 , Figure 3-Figure 4 As shown, Figure 2: is a cross-sectional view of the main structure according to an exemplary embodiment. Taking the hair styling tool as a hair dryer as an example, it can be equipped with a wind speed adjustment key, a wind temperature adjustment key and a mode switching key. Exemplarily, the button assembly includes: a wind speed adjustment key for switching different levels of wind speed gears; a wind temperature adjustment key for switching different levels of wind temperature gears; a mode switching key for switching different working modes. Further, the button assembly includes a button and a trigger switch 1071 arranged on the PCBA board 107 corresponding to the aforementioned button arrangement, and the trigger switch 1071 controls the working state of the hair styling tool. The wind speed adjustment key includes a wind speed adjustment button 1031 and a trigger switch 1071 matched with the wind speed adjustment button 1031, the wind temperature adjustment key includes a wind temperature adjustment button 1033 and a trigger switch 1071 matched with the wind temperature adjustment button 1033, and the mode switching key includes a mode switching button 1032 and a trigger switch 1071 matched with the mode switching button 1032. The wind speed adjustment button 1031, the wind temperature adjustment button 1033 and the mode switching button 1032 are integrally arranged to form a button module 103, and the button module 103 is fixedly connected to the annular adapter cover 102, and one of the button module 103 and the annular adapter cover 102 is provided with a positioning column, and the other is provided with a positioning hole. More specifically, the button module 103 is provided with a second positioning hole 1034, and the annular adapter cover 102 is provided with a second positioning column 1025 matched with the second positioning hole 1034.

[0037] Considering the convenience of one-hand operation by the index finger / thumb, the wind speed adjustment button 1031, the wind temperature adjustment button 1033 and the mode switching button 1032 are optionally arranged on the annular adapter cover 102. In this embodiment, the buttons of each key are positioned and installed by the first bracket plate 1012 and the key cap hole 1022 on the annular adapter cover 102. The button layout is based on the natural hand shape of the user when holding the styler, and the best button position is determined through ergonomic analysis. At the same time, the hair dryer switch is placed under the flying saucer part, so that the user can easily touch the switch without changing the holding method when using it, which improves the convenience of one-hand operation.

[0038] In some exemplary embodiments, Figure 3 As shown, considering that the hair styling tool lacks an intuitive indication system, it is difficult for the user to quickly identify the current working state, which reduces the user experience. In this exemplary embodiment, an indicator light 1072 can also be set on the PCBA board 107. The indicator light is used to display the wind speed gear, wind temperature gear and working mode. Accordingly, in order to facilitate user observation, a light-transmitting hole 1023 corresponding to the indicator light is opened on the annular adapter cover 102. Exemplarily, the indicator light is an LED indicator light 1072. By adding an indicator light, the user can more intuitively distinguish the current mode and gear.

[0039] Further optionally, if Figure 6As shown, multiple indicator lights can be provided to distinguish the wind speed gear, wind temperature gear and mode gear, so that the user can intuitively distinguish them. The indicator lights include: multiple wind speed indicator lights 1072A, which are used to display wind speed gears of different levels; multiple wind temperature indicator lights 1072C, which are used to display wind temperature gears of different levels; and multiple mode indicator lights 1072B, which are used to display different working modes. For example, 3 wind speed indicator lights are set to correspond to the wind speed adjustment key, 3 wind temperature indicator lights are set to correspond to the wind temperature adjustment key, and 3 mode indicator lights are set to correspond to the mode switching key.

[0040] Optionally, when a button assembly is provided on the annular adapter cover 102, as shown in FIG. Figure 3-Figure 4 As shown, the wind speed adjustment button 1031 on the left can adjust the wind speed of low, medium and high; the mode switching button 1032 in the middle can switch between the three modes of cold, hot and cold and hot cycle; the wind temperature adjustment button 1033 on the right can adjust the wind temperature of low, medium and high. It should be noted that the corresponding indicator light can also be written with corresponding text to help users better understand the functions of each button and the gear light. The hair styling tool adopts a new button structure. By arranging the button components on the top of the hair styling tool (i.e., on the ring adapter cover 102) and arranging the buttons in a ring, the wind temperature, mode, wind speed and other functions can be controlled, and one-handed easy operation and fast function switching can be achieved. The current working status is displayed through the LED indicator light 1072, which improves the overall user experience and satisfaction.

[0041] In some exemplary embodiments, Figure 1 As shown, the power switch 108 can be set at the corresponding position of the housing 1011 so as to be distinguished from the above-mentioned button assembly. The power switch 108 is used to control the start and stop of the hair styling device. In order to further facilitate one-handed operation, the power switch 108 is set directly below the button assembly. In this example, the button assembly includes three buttons, and the power switch 108 is located at the bottom of the middle button; if the button assembly includes two buttons, then the power switch 108 is located directly below the middle position of the two buttons. The shortest distance between the power switch 108 and the button assembly is d, 20mm≤d≤60mm, which is convenient for one-handed operation. When d>60mm, the power switch is too far away from the button assembly, which is not convenient for one-handed operation; when d<20mm, the power switch is too close to the button assembly, which is not convenient for one-handed operation. In an operation example, the user can operate the power switch with the thumb, and place the index finger on the flying saucer part to control the wind speed adjustment button 1031, the wind temperature adjustment button 1033 and the middle mode switching button 1032 to achieve one-handed control of the hair dryer.

[0042] In order to enhance the technological sense of the product, a decorative lamp 1074 can be further provided on the PCBA board 107. The PCBA board 107 is annular, and the decorative lamp 1074 has a plurality of decorative lamps 1074 distributed in annular shape on the PCBA board 107. The decorative lamp 1074 can correspond to the operation of the power switch 108. A light-transmitting area is provided on the annular adapter cover 102, and the light of the decorative lamp 1074 can be transmitted through the light-transmitting area of ​​the annular adapter cover 102.

[0043] The following describes the assembly and use of the hair styling tool in conjunction with the above-mentioned embodiment of the present application.

[0044] like Figure 1-Figure 6 As shown, a second positioning column 1025 is provided on the inner wall of the annular transfer cover 102, and a second positioning hole 1034 cooperating with the second positioning column 1025 is provided on each button, so that each button can be fixedly connected to the annular transfer cover 102. The annular transfer cover 102 is provided with a key cap hole 1022 for installing the button, and a light-transmitting hole 1023 is provided at the position corresponding to the LED indicator 1072 of the annular transfer cover 102, so as to ensure that the user can intuitively see the status of the indicator when using it. The trigger switch 1071 and the indicator light 1072 corresponding to each button are made by welding and installing corresponding components on a PCB board to obtain a corresponding PCBA board 107.

[0045] There are multiple light holes 1023, and the first bracket plate 1012 includes light holes 10123. The multiple light holes 10123 are independent of each other and correspond to the multiple indicator lights 1072 one by one, ensuring that the light of the indicator lights 1072 can pass through the corresponding light holes 1023 on the annular adapter cover 102 to prevent light leakage. Furthermore, the first bracket plate 1012 also includes multiple retaining ribs that define the light holes 10123, and ribs 10122 that connect the multiple retaining ribs, which improve the structural strength and further prevent light leakage.

[0046] like Figure 1-Figure 5 As shown, more specifically, the second bracket plate 1013 is provided with a first screw hole 10131 and a second screw hole 10132, and the first bracket plate 1012 is provided with a third screw hole 10124. The first screw hole 10131 cooperates with the third screw hole 10124 to fix the first bracket plate 1012 and the second bracket plate 1013 through a connecting member (such as a screw, a rivet, etc.), so as to firmly fix the PCBA board 107 between the first bracket plate 1012 and the second bracket plate 1013; the second screw hole 10132 cooperates with other structures of the handle part 101 to achieve the fixed connection between the second bracket plate 1013 and the handle part 101. The annular adapter cover 102 is provided with a buckle 1024, and the buckle 1024 is detachably connected to the hook 10134 on the second bracket plate 1013.

[0047] A limiting groove 10121 is provided on the first bracket plate 1012 to fix and limit the heating unit 105. The first bracket plate 1012 is sleeved on the outer periphery of the heating unit 105. The outer wall of the heating unit 105 is provided with a protrusion that cooperates with the limiting groove 10121, thereby improving assembly efficiency and ensuring reliable fixation of the two.

[0048] When the user uses the hair styler, he only needs to select the appropriate styling attachment, then turn on the power switch 108, and select the desired wind speed level, wind temperature level, and working mode. Since the button assembly is arranged on the top of the styler through a flying saucer design, the size, shape, and spacing of the buttons are carefully designed to ensure that the user can easily reach and press them when using them, reducing hand fatigue, thereby optimizing the smoothness and efficiency of human-computer interaction, so that the overall appearance of the hair styler is improved while also improving the user experience.
