[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0025] In the following description, the terms "first," "second," "etc." are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions under normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use.

[0026] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0027] like Figure 1 and Figure 2 As shown, in a first aspect, this utility model embodiment provides a handle 1 for connecting a hair styling head 2. The handle 1 includes a housing 11, a first control key 12, a second control key 13, an indicator light 14, and a circuit board 15. A mounting cavity 111 is formed inside the housing 11, and the circuit board 15 is disposed within the mounting cavity 111, and the circuit board 15 is electrically connected to the first control key 12, the second control key 13, and the indicator light 14. Both the first control key 12 and the second control key 13 are connected to the housing 11. It is understood that the first control key 12 and the second control key 13 are different. For example, one of the first control key 12 and the second control key 13 is a power key, which can control the heating element of the hair styling head 2 to be powered on or off; the other of the first control key 12 and the second control key 13 is a function key, for example, which can cause the rotating component in the hair styling head 2 to rotate in different directions. Specifically, one or both of the first control key 12 and the second control key 13 can move radially in the housing 11; one or both of the first control key 12 and the second control key 13 can also move axially in the housing 11. One or both of the first control key 12 and the second control key 13 can pass through the housing 11 and partially protrude from the outside of the housing 11, or they can be flush with the housing 11 to form a whole, or they can be recessed relative to the housing 11. This application does not limit the specific structure of the first control key 12 and the second control key 13, as long as the first control key 12 and the second control key 13 are both electrically connected to the circuit board 15 and enable the hair styling head 2 to perform different functions.

[0028] like Figure 2 and Figure 3As shown, indicator light 14 is disposed on housing 11 and is used at least to indicate the working status of hair styling head 2. For example, indicator light 14 being lit indicates that the heating element of hair styling head 2 is powered on and heating air, while indicator light 14 being off indicates that the heating element of hair styling head 2 is powered off and not heating. Indicator light 14 can also display the working temperature of hair styling head 2. For example, indicator light 14 has different lighting colors. When the color of indicator light 14 switches to red, it indicates that the temperature of hair styling head 2 is high, which can be understood as hair styling head 2 being in high-temperature working mode; when the color of indicator light 14 switches to blue, it indicates that the temperature of hair styling head 2 is low, which can be understood as hair styling head 2 being in low-temperature working mode. Specifically, housing 11 can have through holes through which indicator light 14 can emit light; housing 11 can also be partially made of light-transmitting material so that the light from indicator light 14 can pass through housing 11. The specific arrangement of housing 11 is such that the user can clearly observe the light of indicator light 14.

[0029] like Figure 2 As shown, indicator light 14 is positioned between the first control key 12 and the second control key 13. This arrangement, through the spacing of indicator light 14, increases the distance between the first control key 12 and the second control key 13, making it less likely for the user to accidentally touch the second control key 13 when touching the first control key 12, and vice versa. This reduces the possibility of accidentally touching one control key while intending to use the other, improving user accuracy and experience. Furthermore, due to the significant differences in size, outline, and shape between the indicator light 14 and the control keys, users can intuitively determine the position of the two control keys by feel and orientation. For example, the first control key 12 may be below the indicator light 14, and the second control key 13 above it. After the user touches the indicator light 14, moving downwards from the indicator light 14 reveals the first control key 12, and similarly, moving upwards from the indicator light 14 reveals the second control key 13, further facilitating user operation.

[0030] The handle 1 provided in this embodiment of the utility model is used to connect a hair styling head 2. The handle 1 includes a housing 11, a first control button 12, a second control button 13, an indicator light 14, and a circuit board 15. A mounting cavity 111 is formed inside the housing 11. The circuit board 15 is installed in the mounting cavity 111 and is electrically connected to the first control button 12, the second control button 13, and the indicator light 14. Both the first control button 12 and the second control button 13 are connected to the housing 11. The indicator light 14 is disposed on the housing 11 and is used to at least display the working status of the hair styling head 2. The indicator light 14 is located between the first control button 12 and the second control button 13. The distance between the first control button 12 and the second control button 13 is relatively large due to the spacing of the indicator light 14, reducing the possibility of the user accidentally touching one control button when intending to use another. Furthermore, the user can intuitively determine the location of the desired control button based on the relative positions of the two control buttons and the indicator light 14, facilitating user operation and improving the user experience.

[0031] In some embodiments, such as Figure 3 and Figure 4 As shown, at least two indicator lights 14 are provided. The first control key 12, each indicator light 14, and the second control key 13 are arranged at intervals along the length direction of the housing 11. It can be understood that the length direction of the housing 11 represents the direction of maximum dimension of the handle 1 in the three-dimensional coordinate system, and is also the extension direction and axial direction of the housing 11. The multiple indicator lights 14 are arranged between the first control key 12 and the second control key 13, which extends the path from the first control key 12 to the second control key 13, further increasing the distance between the first control key 12 and the second control key 13, thereby further reducing the possibility that the user will accidentally touch another control key when trying to use one control key.

[0032] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing 11 has a first end 112 and a second end 113 opposite each other in the longitudinal direction. The first end 112 is used to connect to the hair styling head 2, and the second end 113 is used to connect to a power source. (Refer to...) Figure 1 The first end 112 is the right end of the housing 11, and the second end 113 is the left end of the housing 11. One of the first control key 12 and the second control key 13 is closer to the first end 112, and the farthest distance from the other of the first control key 12 and the second control key 13 to the first end 112 is L1. Specifically, the first control key 12 may be closer to the first end 112 than the second control key 13, then the farthest distance from the second control key 13 to the first end 112 is L1; in this application Figure 2In the schematic diagram shown, the second control key 13 is closer to the first end 112 than the first control key 12. Therefore, the farthest distance from the first control key 12 to the first end 112 is L1. Taking the farthest distance from the first control key 12 to the first end 112 as an example to explain L1, in the embodiment where the first control key 12 is radially connected to the housing 11 along the handle 1, the distance from the farthest point of the outline of the first control key 12 to the first end 112 represents L1. In the embodiment where the first control key 12 is axially connected to the housing 11 along the handle 1, when the first control key 12 is located at its farthest position from the first end 112, the distance from the farthest point of the outline of the first control key 12 to the first end 112 represents L1. The distance from the first end 112 to the second end 113 is L2, which can be understood as representing the length of the handle 1. L1 is less than or equal to half of L2, meaning that the handle 1 will have at least half its length reserved for the user to hold. The space provided by the handle 1 is large enough to allow ample room for the user to hold it, reducing the possibility of accidentally touching control buttons due to insufficient space when holding the handle 1. Moreover, with this arrangement, the positions of the first control button 12 and the second control button 13 on the handle 1 are precisely in a position where the fingers can easily operate when holding the handle 1, which conforms to ergonomics and helps to improve the user experience.

[0033] In some embodiments, such as Figure 2 As shown, the minimum distance between the first control key 12 and the second control key 13 is L3, where L3 is greater than or equal to 1 / 4 of L2. This "minimum distance between the first control key 12 and the second control key 13" is the interval length between them, meaning the interval length between them is at least greater than or equal to 1 / 4 of the length of the housing 11. This greater distance reduces the possibility of the user accidentally pressing one control key while intending to use another. Simultaneously, it prevents inconvenience in operation due to the excessive distance between the first and second control keys 12 and 13.

[0034] In some embodiments, such as Figure 4As shown, the outline edges of the first control key 12 and the second control key 13 are flush with the outer surface of the housing 11, meaning that the outline edges of the first control key 12 and the second control key 13 are integrated with the outer surface of the housing 11. Of course, in some possible embodiments, the first control key 12 and the second control key 13 may also be recessed in the center, meaning that the outer edges of the first control key 12 and the second control key 13 are integrated with the outer surface of the housing 11, and the center of the first control key 12 and the second control key 13 is recessed towards the inside of the housing 11. Regardless of the specific structural arrangement of the first control key 12 and the second control key 13, neither the first control key 12 nor the second control key 13 protrudes from the housing 11. This makes it less likely for the user to accidentally touch the first control key 12 and / or the second control key 13 while using the handle 1, thus reducing the possibility of accidental touches that could affect normal use.

[0035] In some embodiments, such as Figure 3 As shown, the first control key 12 and / or the second control key 13 includes a push switch 121 and a push cap 122. The push cap 122 is used to receive pressure to control the push switch 121. The push switch 121 is disposed on the circuit board 15 and electrically connected to the circuit board 15. The push cap 122 passes through the housing 11 and moves radially in the housing 11 during the process of receiving external force from the user. That is to say, the first control key 12 and / or the second control key 13 are pressable buttons. Only the first control key 12 can be set as a button, only the second control key 13 can be set as a button, or both the first control key 12 and the second control key 13 can be set as buttons. The buttons have a long lifespan, are easy to operate, have strong waterproof and anti-interference capabilities, are easy to clean, and are convenient for users.

[0036] In some embodiments, the first control key 12 and / or the second control key 13 includes a toggle switch (not shown) and a push-pull cap (not shown). The toggle switch is disposed on and electrically connected to the circuit board 15. The push-pull cap is mounted on the housing 11 and switches to different positions along the length of the housing 11 to control the toggle switch. During the user's pushing or pulling of the push-pull cap, the push-pull cap moves axially in the housing 11. It can be understood that the first control key 12 and / or the second control key 13 are push-pull keys that can receive user push and pull. Only the first control key 12 can be set as a push-pull key, only the second control key 13 can be set as a push-pull key, or both the first control key 12 and the second control key 13 can be set as push-pull keys. The user can change the working state of the hair styling head 2 by pushing or pulling the push-pull key. The push-pull key has obvious physical feedback, which makes it less prone to misoperation. The user can intuitively judge the working state of the hair styling head 2 according to the position of the push-pull cap of the push-pull key, which is also convenient for the user.

[0037] In some embodiments, such as Figure 2 and Figure 3 As shown, the first control key 12 is at least a power key, used to switch the hair styling head 2 and indicator lights 14 on and off. Specifically, pressing the first control key 12 switches the hair styling head 2 to a powered-on or powered-off state. When the hair styling head 2 is powered on, the heating element in the hair styling head 2 starts heating, and at least one indicator light 14 is lit. When the hair styling head 2 is powered off, the heating element in the hair styling head 2 does not heat, and all indicator lights 14 are off. The first control key 12 can be a power key or a composite key with power function. For example, the first control key 12 can also adjust the heating temperature of the hair styling head 2. The second control key 13 is at least a rotation direction adjustment key, used to adjust the working state of the hair styling head 2. Specifically, the second control key 13 can make the rotating part in the hair styling head 2 rotate in different directions. Of course, the second control key 13 can also be a composite key with rotation direction adjustment function. For example, the first control key 12 and / or the second control key 13 can also adjust the rotation speed of the rotating component in the hair styling head 2, or act as a temperature adjustment key to adjust the working temperature of the hair styling head 2, or act as a timer key to control the working time of the hair styling head 2, or turn the negative ion function of the hair styling head 2 on or off. The second control key 13 controls the number of indicator lights 14 and / or the lighting status of each indicator light 14. Specifically, the control functions of the second control key 13 on the indicator lights 14 include, but are not limited to, controlling the number of indicator lights 14 that are lit, the lighting color of each indicator light 14, and the lighting intensity of each indicator light 14. Users can press or pull different control keys as needed to achieve different needs, and judge the working status of the hair styling head 2 based on the physical feedback of the indicator lights 14.

[0038] For example, such as Figure 1 and Figure 4As shown, the second control key 13 can be used as a temperature adjustment key, and the number of lit indicator lights 14 is positively correlated with the working temperature of the hair styling head 2. Indicator lights 14 provide physical feedback, allowing users to intuitively determine the working temperature of the hair styling head 2 based on the number of lit lights. For example, the hair styling head 2 can operate at temperatures of 160℃, 180℃, and 200℃ to accommodate different hair types. 160℃ corresponds to the low-temperature mode of the hair styling head 2, 180℃ to the medium-temperature mode, and 200℃ to the high-temperature mode. There are three indicator lights 14. When the hair styling head 2 is in the high-temperature mode of 200℃, all three indicator lights 14 are lit; when the hair styling head 2 is in the medium-temperature mode of 180℃, two indicator lights 14 are lit and one is off; when the hair styling head 2 is in the low-temperature mode of 160℃, one indicator light 14 is lit and two are off. It is understandable that when the power to the hairdresser is cut off, all three indicator lights 14 will be off.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the second control button 13 is positioned between the first control button 12 and the first end 112. That is, the second control button 13 is closer to the first end 112 than the first control button 12, so L1 mentioned above is the furthest distance between the second control button 13 and the first end 112. As can be seen from the above, the first control button 12 is the power button, the second control button 13 is the function button, the first end 112 is the end connecting the handle 1 to the hair styling head 2, and the second end 113 is the end connecting the handle 1 to the power source. This arrangement makes the second control button 13 (power button) closer to the second end 113 and closer to the power cord than the first control button 12 (function button), facilitating electrical connection between the power cord and the second control button 13; the first control button 12 (function button) is closer to the first end 112 and closer to the hair styling head 2 than the second control button 13 (power button), facilitating electrical connection between the hair styling head 2 and the first control button 12, and facilitating wiring within the handle 1.

[0040] In some embodiments, such as Figure 1 and Figure 3As shown, the handle 1 also includes a motor 16, which is disposed within the mounting cavity 111. The motor 16 drives at least a portion of the hair styling head 2 to rotate, meaning the hair styling tool provided in this embodiment can be used as an automatic curling iron. The motor 16 is electrically connected to the circuit board 15. The first control key 12 is used to turn the motor 16 on and off. When the motor 16 is powered on, the heating element in the hair styling head 2 begins to heat; when the motor 16 is powered off, the heating element in the hair styling head 2 does not heat. The second control key 13 is used at least to drive the motor 16 and adjust the rotation direction of the motor 16. When the second control key 13 drives the motor 16 to rotate the rotating component in the hair styling head 2, the hair styling head 2 automatically wraps the hair, simplifying the hair wrapping operation for the user during the curling process. The rotation direction of the motor 16 can be adjusted via the second control key 13 to adjust the rotation direction of the rotating component in the hair styling head 2, thereby curling the hair on the left and right sides of the user's hair. When the second control key 13 does not drive the motor 16, the rotating component in the hair styling head 2 stops rotating. However, the heating element in the hair styling head 2 can be continuously heated to style the hair into curls using the first control key 12. The motor 16 is located at one end of the circuit board 15 in the thickness direction. Figure 3 The lower end), the first control key 12, the second control key 13 and the indicator light 14 are located at the other end of the motor 16 in the thickness direction ( Figure 3 (The upper part). This design facilitates the electrical connection of the first control key 12, the second control key 13, and the indicator light 14 to the circuit board 15, and also facilitates the electrical connection of the motor 16 to the circuit board 15, reducing the possibility of wire winding during wiring.

[0041] Secondly, this utility model embodiment also provides a hair styling tool, such as... Figure 1 As shown, the hair styling tool includes a hair styling head 2 and the aforementioned handle 1. Therefore, the hair styling tool has the same technical effect as the handle 1, namely, reducing the possibility of the user accidentally touching different control keys when trying to use the control keys, thus improving the user experience. The hair styling head 2 is connected to the handle 1. Specifically, the hair styling head 2 can be detachably connected to the handle 1 through a threaded connection structure or a snap-fit ​​structure. The hair styling head 2 can also share the housing 11 of the handle 1 and be fixedly connected to the handle 1. The hair styling head 2 is used for curling and / or straightening hair. The hair styling head 2 can be used solely as a curling iron to curl hair, or solely as a straightener to straighten hair. The hair styling head 2 can also combine both curling and straightening functions. For example, the hair styling head 2 can be equipped with a curling iron composed of two openable plates. The opposite side of the two plates is flat, and the opposite side of the two plates is curved to wrap around the hair and achieve curling. With the two plates open, the user can place their hair into the gap between the plates, then close the plates again to clamp the hair and heat it to straighten it. With the plates closed, the user can wrap their hair around the outer curved surfaces of the plates and heat it to curl it.

[0042] Of course, it is understandable that, such as Figure 1 and Figure 3 As shown, a motor 16 is provided inside the handle 1, and in an embodiment where the motor 16 can drive the hair styling head 2 to rotate, the hair styling tool can achieve automatic hair curling. That is, after the user puts the hair into the hair styling head 2, the user can drive the rotating part in the hair styling head 2 to rotate, so as to automatically wrap the hair and achieve automatic hair curling, reducing the difficulty of using the hair styling head 2 and making it convenient for the user.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
