Description

Hair dryer and hair care products

[0001] This application claims priority to the patent applications filed with the State Intellectual Property Office of the People's Republic of China under application numbers CN202422742203.X, CN202410678548.5, CN202410824967.5, and CN202421970914.6, all of which are disclosed herein for reference. Technical Field

[0002] This application relates to the field of household appliance technology, and in particular to nozzles and hair care appliances. Background Technology

[0003] Hair dryers are common household appliances. Some hair dryers on the market now feature various replaceable nozzles, allowing for styling while drying hair. For example, nozzles with negative ion technology carry negative ions in the airflow, helping to keep hair shiny and moisturized; nozzles with oil-based components carry atomized oil in the airflow, making hair more moisturized and fragrant. When used alone or with different types of nozzles, the motor and heating element need to be matched with the appropriate power. Therefore, the control panel of such hair dryers needs to recognize the current status and control the motor and heating element accordingly.

[0004] In related technologies, when the control board identifies the current state, it either uses a receiver on the body and different sensors on different air nozzles to receive corresponding signals for judgment, or it uses a push rod on the body and different docking structures on different air nozzles to determine the state by connecting the push rod to the corresponding docking structure. However, the first method is prone to misjudgment due to sensor problems, while the second method has high requirements for structural design. Therefore, there is an urgent need for a recognition method with low structural design requirements and high reliability of recognition results.

[0005] Some nozzles have complex installation structures for their functional components, making the disassembly and assembly process cumbersome if replacement or repair is required. Other nozzles have simple installation structures for their functional components, such as those installed using magnetic attraction, but their installation reliability is insufficient, and the functional components are prone to falling off.

[0006] In some hair dryers, when the nozzle is not installed on the body, the electrical connection structure on the body used for electrical connection with the nozzle can be easily damaged by accidental contact.

[0007] In addition, existing hair care devices suffer from complex switching structures and uneven airflow from the air outlet.

[0008] Some nozzles also have an airflow function; however, the airflow can cause hair to become tangled and more likely to get stuck on the comb, which not only increases combing resistance but also affects the combing effect, thus impacting the user experience.

[0009] In addition, the existing hair curler shell has multiple arc-shaped air guide ribs formed at the position of the second air outlet. These multiple arc-shaped air guide ribs are distributed at intervals along the length of the hair curler shell. The second air outlet needs to be formed by the arc-shaped air guide ribs of the hair curler shell and the first air outlet of the inner tube. The unreasonable design of this hair curler shell structure makes it difficult to control the manufacturing and assembly process. Summary of the Invention

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0091] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0092] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0093] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0094] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0095] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

The body 20 includes a control board 832, a motor 833 electrically connected thereto, and a second electrical connector 700. The nozzle 10 is detachably mounted to the body 20. The body 20 has an air inlet 811. When the hair care appliance is in the mounted state with the nozzle 10 mounted to the body 20, the motor 833 provides high-speed air. External airflow flows into the body 20 through the air inlet 811, is accelerated by the motor 833, and then flows through the nozzle 10 before being discharged. The air outlet 812 of the body 20 has a recessed accessory mounting groove 821. The second electrical connector 700 is located in the accessory mounting groove 821. In the mounted state, the nozzle 10 extends into the accessory mounting groove 821, and the first electrical connector 600 and the second electrical connector 700 are in contact and connected.

[0097] In the aforementioned hair care appliance, the nozzle 10 is detachably attached to the body 20. Therefore, by detaching and attaching different nozzles 10, the hair care appliance can have different care or styling functions. In the installed state, the nozzle 10 extends into the accessory mounting slot 821, and the first electrical connector 600 and the second electrical connector 700 are in contact and conductive, thus achieving electrical connection between the nozzle 10 and the body 20. Since the second electrical connector 700 is located in the recessed accessory mounting slot 821, the accessory mounting slot 821 can protect the second electrical connector 700, making it less likely to be touched by the user and thus less likely to be damaged due to accidental contact.

[0098] Specifically, the air outlet of the body 20 is located at its outlet end 812, and the air inlet 811 is located on the outer side wall of the body 20, away from the outlet end 812. From the perspective of the attached drawings, the outlet end 812 of the body 20 is its top, and the nozzle 10 is connected to the top of the body 20. The axes of the two are perpendicular, and the radial direction of the nozzle 10 is parallel to the axis of the body 20. The air inlet 811 is located at the bottom region of the outer side wall of the body 20. After the airflow enters through the air inlet 811, it flows upward through the motor 833, then flows from the top of the body 20 into the nozzle 10, and turns 90 degrees within the nozzle 10 before being discharged.

[0099] Referring to Figures 2 to 5 and Figure 13, in some embodiments, the first electrical connector 600 includes a spring pin 610, and the second electrical connector 700 includes a conductive sheet 710 located in the accessory mounting groove 821 and used to elastically abut against the spring pin 610, the conductive sheet 710 being electrically connected to the control board 832.

[0100] From the perspective of the attached diagram, the accessory mounting groove 821 is formed by a downward recess from the top of the body 20, and the nozzle 10 extends downward into the accessory mounting groove 821. The needle body 611 of the spring needle 610 can extend and retract vertically to elastically abut against the conductive sheet 710, thereby realizing the electrical connection between the body 20 and the nozzle 10.

[0101] In the above embodiment, the conductive sheet 710 is located in the accessory mounting slot 821, so the conductive sheet 710 can be protected by the accessory mounting slot 821, so that it is in a position that is not easily touched, and thus is not easily damaged by accidental contact.

[0102] In other embodiments, the types of the first electrical connector 600 and the second electrical connector 700 can be interchanged. That is, the second electrical connector 700 includes a spring pin 610, and the first electrical connector 600 includes a conductive sheet 710. In this case, the spring pin 610 is located in the accessory mounting slot 821. In the installed state, the conductive sheet 710 extends into the accessory mounting slot 821 and makes contact with the spring pin 610 located in the accessory mounting slot 821 to conduct electricity.

[0103] In the embodiment shown in the accompanying drawings, the first electrical connector 600 and the second electrical connector 700 are provided with two sets of matching components, each set having the same structure.

[0104] Referring to Figures 3 to 7, in some embodiments, the body 20 includes a bracket 820, with the motor 833 and control board 832 both mounted within the bracket 820. The second electrical connector 700 includes a wire connection segment 720 electrically connected to the control board 832, and a fixing piece 730 connecting the wire connection segment 720 and the conductive sheet 710. The conductive sheet 710 is bent relative to the fixing piece 730, and the conductive sheet 710 is inserted into the bracket 820, while the fixing piece 730 is fixed to the bracket 820. In some embodiments, the conductive sheet 710, the wire connection segment 720, and the wire connection segment 720 are integrally formed from a conductive metal material to reduce assembly costs.

[0105] Referring also to Figure 1, specifically, the body 20 includes a hollow cylindrical housing 810. From the perspective of the figure, the air inlet 811 is located at the bottom region of the outer wall of the housing 810. The bracket 820 is generally a hollow cylinder and is installed inside the housing 810. The area on the bracket 820 corresponding to the air inlet 811 is partially perforated so that the airflow entering through the air inlet 811 can flow through the perforated area to reach the interior of the bracket 820 and then through the motor 833.

[0106] More specifically, the fixing plate 730 extends along the axial direction of the body 20, and the conductive plate 710 extends along the radial direction of the body 20, forming an "L" shape. The conductive plate 710 is inserted into the bracket 820, while the fixing plate 730 is fixed to the bracket 820. Therefore, the accuracy of the fixing position of the fixing plate 730 can be improved by the insertion and connection, thereby improving the accuracy of the installation position of the conductive plate 710.

[0107] Referring to Figures 4 to 7, in some embodiments, the conductive sheet 710 includes a contact portion 711 connected to the fixing sheet 730, and a protrusion 712 protruding outward from one end of the contact portion 711 away from the fixing sheet 730. The contact portion 711 is used to elastically abut against the spring pin 610. The outer side wall of the bracket 820 is provided with a recessed receiving groove 822. A portion of the bottom wall of the accessory mounting groove 821 is recessed to form a limiting groove 823 communicating with one end of the receiving groove 822. The bracket 820 is also provided with a slot 824 located inside and communicating with the limiting groove 823. The wire connecting section 720 and the fixing sheet 730 are received in the receiving groove 822, the contact portion 711 is located in the limiting groove 823, and the protrusion 712 is inserted into the slot 824.

[0108] From the perspective of the attached drawings, both the limiting groove 823 and the slot 824 extend radially along the body 20. The top of the receiving groove 822 communicates with the outer side of the limiting groove 823, and the outer side of the slot 824 communicates with the inner side of the limiting groove 823. The width of the protrusion 712 is smaller than the width of the contact portion 711. By placing the contact portion 711 in the limiting groove 823 and simultaneously inserting the protrusion 712 into the slot 824, the freedom of the conductive sheet 710 in all directions can be effectively restricted, ensuring the stability of its installation position.

[0109] In some embodiments, the retaining piece 730 is secured within the receiving groove 822 by a threaded fastener. Preferably, the surface of the threaded fastener is coated with an insulating layer.

[0110] Specifically, the threaded fastener is a screw. A through hole is provided on the fixing plate 730 for the screw to pass through, and a corresponding screw hole is provided on the groove wall of the receiving groove 822. After the screw passes through the through hole, it is threaded into the screw hole. Since the screw is usually a metal part, in order to suppress its contact with the metal fixing plate 730 and thus prevent accelerated electro-corrosion of the fixing plate 730, the screw can be specially treated, for example, by coating the screw surface with an insulating layer.

[0111] In some embodiments, the width of the limiting groove 823 is less than 5 mm; and / or the depth of the accessory mounting groove 821 is greater than 5 mm.

[0112] By limiting the depth of the accessory mounting groove 821 and the width of the limiting groove 823, the contact portion 711 of the conductive sheet 710 can be placed in a narrower and deeper position, further reducing the chance of accidental contact by the user.

[0113] Referring to Figures 3 to 5, in some embodiments, the body 20 includes a heating wire 834, a bracket 820, and a perforated protective cover 835. The protective cover 835, the motor 833, and the control board 832 are all installed inside the bracket 820. The heating wire 834 is located on the side of the motor 833 away from the air inlet 811, and the protective cover 835 is located on the side of the heating wire 834 away from the motor 833. An annular accessory mounting groove 821 is formed between the outer wall of the protective cover 835 and the inner wall of the bracket 820.

[0114] From the perspective of the attached diagram, the air inlet 811, control board 832, motor 833, heating wire 834, and protective cover 835 are arranged sequentially from bottom to top. The heating wire 834 and control board 832 are electrically connected, and the control board 832 can control the heating wire 834 to heat the airflow. The protective cover 835 can isolate and protect the heating wire 834 to prevent users from being burned by contact with the heating wire 834, and can also block foreign objects from entering the heating wire 834 and causing malfunctions. Because the protective cover 835 is perforated, it does not obstruct the airflow. The perforation at the end of the protective cover 835 forms the air outlet of the body 20. The airflow can flow in through the air inlet 811, and then flow sequentially through the control board 832, motor 833, heating wire 834, and protective cover 835 before flowing into the air nozzle 10.

[0115] Referring to Figure 1, a power cord 831 is also connected to the bottom of the bracket 820. One end of the power cord 831 is electrically connected to the control board 832, and the other end is used to connect to an external power source. Based on this arrangement, the control board 832 and the heating wire 834 are separated by the motor 833, with a relatively large distance between them. This helps to minimize the impact of the high temperature at the heating wire 834 on the performance of the control board 832.

[0116] In other embodiments, the power cord 831 can be removed, and a battery can be used for power supply. Alternatively, the power cord 831 and the battery can coexist, with the power cord 831 providing direct power or charging the battery.

[0117] Preferably, a filter screen is provided between the air inlet 811 and the control board 832 to filter the incoming airflow and prevent dust from contaminating the electrical components.

[0118] Referring to Figure 4, and Figures 8 to 10, in some embodiments, the nozzle 10 includes a connector 400, the end of which is annular and inserted into the accessory mounting groove 821. A spring pin 610 protrudes from the connector 400 and is exposed. Airflow from the body 20 flows into the nozzle 10 through the connector 400.

[0119] In some embodiments, the connector 400 includes a connector side plate 410 and a connector end plate 420 connected to the end of the connector side plate 410 facing away from the body 20. The end of the connector side plate 410 facing away from the connector end plate 420 is inserted into the accessory mounting groove 821 to allow airflow into the body 20.

[0120] Specifically, the spring pin 610 protrudes from the connector side plate 410. During installation, the end of the connector side plate 410 facing away from the connector end plate 420 is inserted into the accessory mounting slot 821. Simultaneously, the spring pin 610 protruding from the connector side plate 410 and the conductive piece 710 in the accessory mounting slot 821 make contact and conduct electricity. In this way, not only can an electrical connection be achieved between the nozzle 10 and the body 20, but the groove wall between the connector side plate 410 and the accessory mounting slot 821 can also have good sealing performance, and airflow loss is not easily caused when airflow from the body 20 flows into the nozzle 10.

[0121] Referring to Figure 21, the connector side plate 410 is roughly annular, with a through-hole 411. Airflow within the body 20 flows out through the protective cover 835, then into the inner side of the connector side plate 410. After colliding with the connector end plate 420, it changes direction, flowing from the inside out through the through-hole 411 to the outer side of the connector side plate 410, and then continues to flow through other components in the nozzle 10. The specific flow path will be described in detail later.

[0122] Referring to Figures 8 to 10, in some embodiments, the connector 400 includes a protective plate 430 protruding outward from the connector side plate 410, the protective plate 430 being located outside the spring pin 610.

[0123] Specifically, the protective plate 430 and the connector side plate 410 are integrally formed as a single unit, with the upper part of the connector side plate 410 protruding outwards, thus increasing the strength of the protective plate 430. By providing the protective plate 430, the spring pin 610 can be protected during the individual handling of the nozzle 10, preventing damage. Furthermore, the outward protrusion of the protective plate 430 relative to the connector side plate 410 provides a foolproof installation method for the nozzle 10, facilitating installation.

[0124] Referring to Figures 8 to 11, in some embodiments, the guard plate 430 and the connector side plate 410 are connected by a boss 440 protruding from the end of the connector side plate 410, the boss 440 having a guide wall 441 for engaging with a guide ramp 8211 on the bottom wall of the accessory mounting groove 821.

[0125] When the connector 400 is inserted into the accessory mounting slot 821, the inclined guide arm can contact and engage with the guide slope 8211 to guide the spring pin 610 to accurately reach the contact portion 711 of the conductive sheet 710 and make contact with it.

[0126] Referring to Figures 12 and 13, in some embodiments, the spring needle 610 includes a needle body 611, a needle seat 612, an inner elastic member 613, and a contact ball 614. The inner elastic member 613 and the contact ball 614 are both built into the needle seat 612. Part of the needle body 611 extends into the needle seat 612, and part of it extends out of the needle seat 612. The contact ball 614 is located between the needle body 611 and the inner elastic member 613. The inner elastic member 613 is used to apply an elastic force toward the conductive sheet 710 to the needle body 611 through the contact ball 614.

[0127] Specifically, when the inner elastic element 613 is in a compressed state, it has a tendency to stretch and rebound. Its rebound force will be transmitted to the needle body 611 through the contact ball 614, causing the needle body 611 to tend to extend outward toward the needle seat 612, so that the needle body 611 can always elastically abut against the conductive sheet 710.

[0128] Referring to Figures 8, 12 and 13, in some embodiments, the nozzle 10 includes a functional component 500 for performing a specific function, a needle holder 612 and the functional component 500 are electrically connected, a needle body 611 is clearance-fitted with the needle holder 612 and the two are electrically connected, and the end face of the needle body 611 near the contact ball 614 is a bevel.

[0129] Specifically, the functional component 500 can be an essential oil atomizing component, a negative ion component, or other common components with specific functions. Referring also to Figures 2, 3, and 7, as previously described, the control board 832 is electrically connected to the conductive sheet 710, the conductive sheet 710 is electrically connected to the needle body 611, the needle body 611 is electrically connected to the needle holder 612, and the needle holder 612 is electrically connected to the functional component 500. Therefore, the control board 832 can control the operation of the functional component 500, enabling it to perform its corresponding functions.

[0130] Because the needle body 611 and the needle holder 612 are fitted with a clearance, and the bottom end of the needle body 611 is beveled, when the needle body 611 contacts the conductive sheet 710 and is squeezed by the conductive sheet 710 to retract into the needle holder 612, the beveled shape of the bottom end of the needle body 611 will deflect the direction of the force, thus tilting it relative to the needle holder 612. This allows the outer wall of the needle body 611 to directly contact the inner wall of the needle holder 612, achieving electrical connection. Compared to the method where the needle body 611 and the needle holder 612 are sequentially connected via a contact ball 614 and an elastic element 613 inside the holder, the above embodiment can reduce the resistance and reduce circuit loss.

[0131] Preferably, the needle body 611 and the needle base 612 are made of copper, copper-plated metal, or copper-containing metal to improve their conductivity.

[0132] Referring to Figures 4, 14 and 15, in some embodiments, the nozzle 10 has a slot 412 with one end open, and the body 20 has a locking block 825. When the body 20 and the nozzle 10 are aligned, the locking block 825 can enter the slot 412. When the aligned body 20 and the nozzle 10 rotate relative to each other and move closer to each other along the axial direction of the body 20, the locking block 825 is engaged in the slot 412.

[0133] Once the body 20 and the nozzle 10 are aligned, the locking block 825 enters the slot 412. Then, simply rotating and moving the body 20 and the nozzle 10 relative to each other will allow the locking block 825 to slide deep into the slot 412, thus engaging the body 20 and the nozzle 10. Conversely, rotating and moving the body 20 and the nozzle 10 in opposite directions will allow the locking block 825 to exit the slot 412, separating the body 20 and the nozzle 10.

[0134] Specifically, the locking block 825 protrudes from the inner side wall of the accessory mounting groove 821, and the locking groove 412 is provided on the outer side wall of the connector side plate 410 in the connector 400. The end of the locking groove 412 facing away from the connector end plate 420 is open, forming an entrance for the locking block 825 to enter. When the connector 400 is inserted into the accessory mounting groove 821 and the position is aligned, the locking block 825 is exactly located at the entrance of the locking groove 412.

[0135] Referring to Figures 4, 14 and 15, in some embodiments, the body 20 includes a locking member 841 and a locking elastic member 842 connected together. When the locking block 825 is engaged in the slot 412, the locking elastic member 842 is used to apply an elastic force toward the nozzle 10 to the locking member 841 so that the locking member 841 is inserted into the slot 412 to prevent the locking block 825 from exiting the slot 412.

[0136] By cooperating with the locking element 841 and the locking elastic element 842, the positions of the nozzle 10 and the body 20 can be locked after the locking block 825 is inserted into the locking slot 412, so as to prevent the nozzle 10 from being dislodged from the body 20 due to the relative rotation and movement of the two in opposite directions.

[0137] Referring to Figures 4, 14, and 15, in some embodiments, the locking member 841 includes a locking part 8411, a transmission part 8412, and a push button 8413. The locking part 8411 and the push button 8413 are both fixed to the transmission part 8412, and the locking part 8411 and the locking elastic member 842 are respectively located at both ends of the transmission part 8412. The locking elastic member 842 is used to push the locking part 8411 closer to the air nozzle 10 through the transmission part 8412. The push button 8413 is configured to be operablely movable to push the locking part 8411 away from the air nozzle 10 through the transmission part 8412.

[0138] Specifically, the locking elastic element 842 is in a compressed state, with one end abutting against the bracket 820 and the other end abutting against the transmission part 8412. The transmission part 8412 is slidably connected to the bracket 820, and the push button 8413 is exposed through the housing 810 for the user to push. The locking elastic element 842 can push the transmission part 8412 through its stretching and rebound force, thereby pushing the locking part 8411 closer to the nozzle 10, so that the locking part 8411 is inserted into the entrance of the slot 412, preventing the locking block 825 from exiting the slot 412. The user can push the push button 8413 to push the transmission part 8412, thereby pushing the locking part 8411 out of the slot 412, releasing the position lock on the nozzle 10 and the housing 20, and realizing the removal and replacement of the nozzle 10.

[0139] In other embodiments, the push button 8413 can be replaced with a button, and a conversion structure capable of changing the motion mode can be provided between the button and the transmission part 8412 to convert the pressing of the button into the movement of the transmission part 8412.

[0140] Referring to Figure 1, in some embodiments, the housing 810 is also equipped with a power switch 851, a speed control button 852, and a cool air switching button 853. A push button 8413 is located on the side of the three buttons opposite to the air inlet 811. The area between the three buttons and the air inlet 811 is the area for the user's hand to hold. This allows the push button 8413 to be closer to the air outlet of the housing 20, i.e., closer to the nozzle 10, compared to the three buttons, thus allowing the transmission part 8412 to be made shorter. At the same time, the push button 8413 is located opposite the three buttons to prevent accidental activation of the push button 8413 while operating the three buttons, which could cause instability in the connection between the housing 20 and the nozzle 10.

[0141] Referring to Figures 8, 12 and 16, in some embodiments, the nozzle 10 includes a functional component 500 for performing a specific function, the first electrical connector 600 includes a contact piece 640 electrically connected to the spring pin 610, the functional component 500 includes a circuit board 540 and a pin 580, one end of the pin 580 is electrically connected to the circuit board 540 and the other end is electrically connected to the contact piece 640.

[0142] Specifically, the needle holder 612 and the contact piece 640 of the spring needle 610 are electrically connected. Further, the first electrical connector 600 includes a substrate 620 and a wire 630, the needle holder 612 and the substrate 620 are soldered to achieve electrical connection, and the substrate 620 and the contact piece 640 are electrically connected through the wire 630.

[0143] Referring to Figures 8, 12, 16 and 20, in some embodiments, the nozzle 10 includes an air outlet sleeve 300, a functional component 500 is installed inside the air outlet sleeve 300, and a contact piece 640 includes a fixing part 641 and a connecting part 642 that are connected to each other and bent relative to each other. The connecting part 642 is inserted into the air outlet sleeve 300, the fixing part 641 is fixed to the air outlet sleeve 300, and the end of the pin 580 facing away from the circuit board 540 elastically abuts against the connecting part 642.

[0144] Specifically, in the contact piece 640, the fixing part 641 extends axially along the nozzle 10, and the connecting part 642 extends radially along the nozzle 10, forming an "L" shape. The connecting part 642 is inserted into the air outlet sleeve 300, while the fixing part 641 is fixed to the air outlet sleeve 300. Therefore, the accuracy of the fixing position of the fixing part 641 can be improved through the insertion fit, thereby improving the accuracy of the installation position of the contact piece 640.

[0145] In some embodiments, the fixing part 641 is fixed to the air outlet sleeve 300 by threaded fasteners.

[0146] Referring to Figures 12, 16 and 17, in some embodiments, the functional component 500 has a pin cavity 511 for receiving a pin 580, and the air outlet sleeve 300 is provided with a contact plate slot 311 and a pin hole 312. The pin hole 312 communicates with the contact plate slot 311 and the pin cavity 511. The connecting part 642 is inserted into the contact plate slot 311, and the pin 580 passes through the pin hole 312 and elastically abuts against the connecting part 642.

[0147] The specific structure of the insert pin 580 is similar to that of the spring pin 610 in the aforementioned embodiment, and will not be described again here.

[0148] Referring to Figures 8, 17, 19 to 21, and 23, in some embodiments, the nozzle 10 includes a housing assembly, an outlet sleeve 300, a functional component 500, and a mounting structure. The outlet sleeve 300 is connected to the housing assembly and is hollow inside. The housing assembly and the inner side of the outlet sleeve 300 together form a mounting cavity 101. The mounting structure includes a fastener 330 and a fixing groove 571. One of the fastener 330 and the fixing groove 571 is disposed in the functional component 500, and the other is disposed in the mounting cavity 101. The functional component 500 is configured to enter the mounting cavity 101 along the axial direction of the outlet sleeve 300 (i.e., the axial direction of the nozzle 10), so that the fastener 330 elastically retracts radially along the outlet sleeve 300 until the fastener 330 is engaged in the fixing groove 571.

[0149] The aforementioned nozzle 10, together with the housing assembly and the inner side of the outlet sleeve 300, forms an installation cavity 101, providing space for the installation of the functional component 500. One of the fixing member 330 and the fixing groove 571 is located in the functional component 500, and the other is located in the installation cavity 101. When the functional component 500 enters the installation cavity 101 axially along the outlet sleeve 300, the fixing member 330 is compressed, causing it to elastically retract radially along the outlet sleeve 300 until it reaches the position of the fixing groove 571. Since the fixing groove 571 provides space for the fixing member 330, it can elastically extend and engage with the fixing groove 571, thus completing the installation of the functional component 500. Conversely, when the functional component 500 needs to be disassembled, it only needs to be moved axially out of the mounting cavity 101 along the air outlet sleeve 300. The fixing member 330 will then be compressed again and elastically retract out of the fixing groove 571 until the functional component 500 is removed from the mounting cavity 101. Therefore, when disassembling or assembling the functional component 500, it is only necessary to move it axially along the air outlet sleeve 300, making the disassembly and assembly operation relatively simple. Furthermore, after the functional component 500 is installed, the fixing member 330 elastically engages with the fixing groove 571. The fixing groove 571 restricts the position of the fixing member 330, preventing it from easily shifting or falling out. Sufficient external force must be applied to make the fixing member 330 elastically retract and exit the fixing groove 571 for disassembly to be achieved. Therefore, after the functional component 500 is installed, it has high installation reliability and will not easily fall off.

[0150] The nozzle 10 in the above embodiments can be detachably connected to the body 20, as in the aforementioned embodiments, or it can be integrally connected to the body 20, as in the following embodiments.

[0151] Referring to Figures 17, 19 and 23, in some embodiments, the mounting structure includes a mounting elastic member 340, the outer side wall of the functional component 500 is provided with a recessed fixing groove 571, the air outlet sleeve 300 has a mounting hole 313 communicating with the mounting cavity 101, one end of the mounting elastic member 340 abuts against the air outlet sleeve 300, and the other end abuts against the fixing member 330, so that the fixing member 330 passes through the mounting hole 313 and extends into the mounting cavity 101.

[0152] Specifically, when the mounting elastic element 340 is in a compressed state, its tensile rebound force pushes the fixing element 330 into the mounting cavity 101 through the mounting hole 313, causing it to protrude from the cavity wall of the mounting cavity 101. When the functional component 500 enters the mounting cavity 101, the outer wall of the functional component 500 will squeeze the fixing element 330, causing it to exit the mounting cavity 101 and retract into the mounting hole 313. When the functional component 500 moves to the point where the fixing element 330 and the fixing groove 571 are aligned, the mounting elastic element 340 rebounds, pushing the fixing element 330 into the mounting cavity 101 through the mounting hole 313 and locking it into the fixing groove 571. During installation, when the fixing element 330 jumps over the edge of the fixing groove 571 and locks into the fixing groove 571, the plastic parts will collide and make a sound to remind the user that the installation is complete.

[0153] In other embodiments, the positions of the fixing member 330 and the fixing groove 571 can be interchanged. That is, the fixing groove 571 is disposed on the cavity wall of the mounting cavity 101, the fixing member 330 is disposed on the functional component 500, and correspondingly, the mounting elastic member 340 is also disposed on the functional component 500.

[0154] In other embodiments, the installation of the elastic element 340 can be omitted, and the fixing element 330 can be directly set as an elastic, telescopic component that can be inserted into or removed from the fixing groove 571 by its own telescopic movement.

[0155] Referring to Figures 17 and 19, in some embodiments, the end of the fastener 330 facing away from the mounting elastic member 340 is tapered, and the end of the fastener 330 facing away from the mounting elastic member 340 has the smallest size.

[0156] This design allows the portion of the fastener 330 that extends into the mounting cavity 101 to be conical, thereby reducing the difficulty of inserting and removing it from the fixing groove 571, making it easier for users to disassemble and assemble.

[0157] Referring to Figures 17, 19 and 20, in some embodiments, the end of the fastener 330 facing away from the mounting elastic member 340 is sealed to the groove wall of the fixing groove 571.

[0158] Specifically, the conical surface of the fastener 330 and the groove wall of the fixing groove 571 are completely fitted together to achieve a sealed connection, so as to prevent airflow from leaking through this point and ensure that the airflow can flow into the functional component 500.

[0159] Referring to Figures 17 to 19, in some embodiments, the air outlet sleeve 300 includes a sleeve body 310 and a fixing seat 320. The mounting hole 313 extends radially through the sleeve body 310. The fixing seat 320 is fixed to the outside of the sleeve body 310 to block the mounting hole 313. One end of the mounting elastic member 340 abuts against the fixing seat 320, and the other end abuts against the fixing member 330.

[0160] Specifically, the fixing seat 320 can be fixed to the outside of the sleeve body 310 by snap-fit, or it can be fixed by threaded fastener connection, or the fixing seat 320 can be integrally formed with the sleeve body 310.

[0161] Referring to Figures 17, 19 and 23, in some embodiments, the fixing groove 571 is annular, and multiple sets of matching installation elastic elements 340 and fixing elements 330 are arranged at intervals along the circumference of the air outlet sleeve 300.

[0162] Preferably, multiple sets of matching installation elastic elements 340 and fixing elements 330 are evenly arranged circumferentially along the air outlet sleeve 300 to increase installation stability. For example, three sets of matching installation elastic elements 340 and fixing elements 330 are provided, with each set spaced 120 degrees apart. Referring to Figures 20, 21, 23, and 24, in some embodiments, the mounting cavity 101 includes a first space 1011 and a second space 1012 arranged axially along the air outlet sleeve 300 and communicating with each other. The radial dimension of the first space 1011 is larger than that of the second space 1012 to form a stepped surface 315 between them. The functional component 500 includes a first part 501 and a second part 502. The radial dimension of the first part 501 is larger than that of the second part 502. The functional component 500 is configured to enter the mounting cavity 101 axially along the air outlet sleeve 300 so that the second part 502 extends into the second space 1012 and the first part 501 extends into the first space 1011 until the end face of the first part 501 abuts against the stepped surface 315, at which point the fastener 330 is engaged in the fixing groove 571.

[0163] By setting up a first space 1011 and a second space 1012 with different radial dimensions, and a first part 501 and a second part 502 with different radial dimensions, the functional component 500 can only enter from the first space 1011 side, and the second part 502 must enter first for successful installation. This prevents mistaken installation and enables quick and accurate installation. Furthermore, the stepped surface 315 between the first space 1011 and the second space 1012 can abut against the end face of the first part 501 during installation to remind the user that the component is now properly installed.

[0164] Referring to Figures 20 to 22, in some embodiments, the housing assembly includes an accessory housing 100 and a rear cover 200 connected together. The air outlet sleeve 300 and the rear cover 200 extend into the accessory housing 100 and are arranged along the axial direction of the air outlet sleeve 300. One end of the air outlet sleeve 300 is connected to the accessory housing 100 and the other end is connected to the rear cover 200. A portion of the air outlet sleeve 300 and the inner side of the rear cover 200 together enclose a second space 1012, and a portion of the air outlet sleeve 300 encloses a first space 1011.

[0165] Specifically, the accessory housing 100 and the rear cover 200 are snap-fitted together or secured by threaded fasteners. The rear cover 200 is hollow, and its inner diameter matches the inner diameter of the portion of the air outlet sleeve 300 near the rear cover 200, thus enclosing the second space 1012. The inner diameter of the portion of the air outlet sleeve 300 facing away from the rear cover 200 is larger, thus enclosing the first space 1011. The functional component 500 is detached from the end of the air outlet sleeve 300 facing away from the rear cover 200.

[0166] Referring to Figures 19 to 21, in some embodiments, the air outlet sleeve 300 includes an open section 316 and a straight section 317 arranged along its own axial direction. The open section 316 and the straight section 317 enclose a first space 1011. The open section 316 is located at the end of the straight section 317 away from the second space 1012. Along the axial direction of the air outlet sleeve 300 and in the direction away from the second space 1012, the open section 316 is in the shape of a gradually expanding trumpet.

[0167] Specifically, during installation, the functional component 500 enters the first space 1011 through the opening section 316, and the aforementioned fastener 330 is installed on the straight section 317. In the above embodiment, the flared design of the opening section 316 facilitates the installation of the functional component 500.

[0168] Referring to Figures 20 and 21, in some embodiments, the rear cover 200 includes a rear cover end plate 210 and a rear cover side plate 220 protruding from one end of the rear cover end plate 210. The rear cover end plate 210 is snapped into the accessory housing 100. One end of the air outlet sleeve 300 abuts against the rear cover side plate 220, and the other end abuts against the accessory housing 100. A portion of the air outlet sleeve 300 and the inner side of the rear cover side plate 220 together enclose a second space 1012.

[0169] Specifically, the rear cover side plate 220 protrudes outward from the central area of ​​the rear cover end plate 210, and the rear cover end plate 210 has a perforated hole 211 corresponding to the position of the second space 1012, so that the user can push the functional component 500 out of the mounting cavity 101 through the perforated hole 211 to complete the disassembly. The snap-fit ​​structure between the rear cover end plate 210 and the accessory housing 100 can be any of the existing technologies, which will not be described in detail here. In addition, the air outlet sleeve 300 can also be snapped onto the accessory housing 100 while abutting against the accessory housing 100 and the rear cover 200, so as to enhance the installation firmness. In this case, the structure on the accessory housing 100 for snapping onto the rear cover 200 and the structure for snapping onto the air outlet sleeve 300 are staggered in the circumferential direction to avoid interference.

[0170] Referring to Figures 18, 20 and 21, in some embodiments, an annular external air duct 102 is formed between the air outlet sleeve 300, the rear cover 200 and the accessory housing 100. The air outlet sleeve 300 has an airflow hole 351 that connects the first space 1011 and the external air duct 102. The airflow flowing into the external air duct 102 through the body 20 can enter the first space 1011 through the airflow hole 351 and be discharged after flowing through the functional component 500.

[0171] Specifically, an external air duct 102 is constructed between the outer wall of the air outlet sleeve 300, the outer wall of the rear cover side plate 220, the inner end wall of the rear cover end plate 210, and the inner wall of the accessory housing 100. Airflow entering the external air duct 102 can flow from the outside inward through the airflow hole 351, reach the first space 1011, and then exit after passing through the functional component 500, blowing onto the hair to be dried. By providing the airflow hole 351, the annular airflow within the external air duct 102 can be redirected through the airflow hole 351, changing from circumferential flow around the air outlet sleeve 300 to radial inward flow, thereby better directing the airflow towards the functional component 500. Furthermore, by forming an annular external air duct 102 between the second housing portion 120 and the sleeve body 310, the airflow can be compressed, making it more concentrated and reaching the first space 1011 through the airflow hole 351, while also reducing noise.

[0172] The airflow passes through functional component 500 before being expelled, thus allowing the exhaled airflow to have different functions depending on the functional component 500. For example, if functional component 500 is an essential oil atomizing component, the exhaled airflow carries atomized essential oil molecules, which can make the hair more moisturized and give it a fragrance. If functional component 500 is a negative ion component, the exhaled airflow carries negative ions, which helps to keep the hair shiny and moisturized.

[0173] In some embodiments, the outer wall of the air outlet sleeve 300 is provided with a flow member 350 extending outward and abutting against the inner wall of the accessory housing 100. The flow member 350 is hollow to form the aforementioned airflow hole 351. A notch 352 communicating with the airflow hole 351 is formed on the flow member 350 in a region near the upstream of the external air duct 102, so as to allow the airflow in the external air duct 102 to be redirected and quickly flow into the airflow hole 351.

[0174] In some embodiments, the air outlet sleeve 300 is provided with multiple sets of flow elements 350 arranged at intervals along its circumference.

[0175] Referring to Figures 19 to 21, in some embodiments, the opening segment 316 and the functional component 500 are clearance-fitted, forming an annular space between them.

[0176] Thus, after the airflow entering the external air duct 102 passes through the airflow hole 351 and reaches the first space 1011, most of the airflow can flow through the functional component 500 and be discharged. Even if a small portion of the airflow does not enter the functional component 500, it can still flow out from the annular space between the opening section 316 and the functional component 500, forming an annular wind. The annular wind and the wind flowing out from the functional component 500 blow together towards the hair, increasing the air volume. Furthermore, it can connect the point-like airflows at several airflow holes 351, transforming them into a smoother annular wind, resulting in a better user experience.

[0177] Furthermore, as mentioned earlier, the end of the fastener 330 facing away from the mounting elastic member 340 is sealed to the wall of the fixing groove 571. Therefore, it can prevent the airflow flowing into the first space 1011 from leaking out from the mating point of the fastener 330 and the fixing groove 571, ensuring that the airflow can flow into the functional component 500.

[0178] Referring to Figures 20 to 22, in some embodiments, the nozzle 10 includes a connector 400 for connection with the body 20. The connector 400 is connected to the accessory housing 100, and the airflow inside the body 20 flows into the external air duct 102 through the connector 400.

[0179] Specifically, the accessory housing 100 includes a first housing portion 110 and a second housing portion 120, which are integrally formed. The first housing portion 110 is connected to the connector 400, and the second housing portion 120 is a hollow cylindrical shape. The aforementioned air outlet sleeve 300, rear cover 200, and functional components 500 are all located within the second housing portion 120. Airflow enters from the first housing portion 110 and exits from the second housing portion 120. The connection structure between the connector 400 and the body 20 has been described in the previous embodiments and will not be repeated here.

[0180] Referring to Figures 9, 21 and 22, in some embodiments, the connector 400 includes a connector end plate 420 connected to the accessory housing 100, and a connector side plate 410 connected to the end of the connector end plate 420 away from the accessory housing 100. The connector side plate 410 is used to connect with the body 20. The connector side plate 410 is provided with a flow hole 411 communicating with the inner space of the connector side plate 410 and the outer air duct 102. The airflow from the body 20 can flow into the inner side of the connector side plate 410 and flow into the outer air duct 102 through the flow hole 411.

[0181] Specifically, the connector end plate 420 and the first housing portion 110 of the accessory housing 100 are connected by threaded fasteners. The connector side plate 410 is roughly annular and has a through-hole 411. After the airflow from the body 20 flows out, it flows into the inner side of the connector side plate 410, and after colliding with the connector end plate 420, it turns and passes through the through-hole 411 from the inside to the outside, reaching the outer air duct 102 on the outside of the connector side plate 410. An annular airflow is formed in the outer air duct 102. When it reaches the airflow hole 351, it flows from the outside to the inside through the airflow hole 351, reaches the first space 1011, and flows through the functional component 500 before being discharged and blown onto the hair to be dried. By setting the connector end plate 420, the airflow can be collided and turned, which is beneficial for the airflow to turn and thus better adapt to the annular flow direction in the outer air duct 102. In addition, the connector end plate 420 can also shield other structures in the second housing portion 120 to prevent dust from entering and prevent accidental contact by the user, and it is also more aesthetically pleasing.

[0182] Preferably, the connector side plate 410 is axially inclined relative to the body 20, which can extend the airflow path and make it easier to turn.

[0183] Referring to Figures 9, 10, 12, 16 and 21, in some embodiments, the nozzle 10 includes a first electrical connector 600, which includes a spring pin 610 and a base plate 620. The base plate 620 is electrically connected to the functional component 500. A portion of the connector side plate 410 is recessed, and the base plate 620 is accommodated between the recessed area 413 of the connector side plate 410 and the accessory housing 100. The spring pin 610 passes through the connector 400 and is used for electrical connection with the body 20.

[0184] By recessing a portion of the connector side plate 410, the substrate 620 can be avoided, providing more space for its installation. Additionally, as previously described, the first electrical connector 600 includes the substrate 620 and wires 630. The pin seat 612 of the spring pin 610 passes through the connector 400, with its lower end exposed and its upper end extending into the accessory housing 100. The lower end of the pin body 611 of the spring pin 610 is used for electrical connection with the body 20. The upper end of the pin seat 612 is soldered to the substrate 620 to achieve electrical connection. The substrate 620 and the contact piece 640 are electrically connected via wires 630, and the contact piece 640 and the circuit board 540 of the functional component 500 are electrically connected via pins 580. More specific electrical connection structures can be found in the aforementioned embodiments and will not be repeated here.

[0185] Referring to Figures 9 and 21, preferably, the flow hole 411 is located on the opposite side of the concave region 413. This provides more space for the flow hole 411.

[0186] Referring to Figures 1, 9, and 21, preferably, the sidewall of the concave region 413 is an inclined plane relative to the axis of the body 20, and the size of the concave region 413 gradually increases radially away from the body 20. That is, from the perspective shown in Figure 21, the sidewall of the concave region 413 is an inclined plane with the left side higher than the right side, and the concave region 413 gradually increases from left to right. This arrangement facilitates the installation of components such as the substrate 620 and the wire 630 in the concave region 413, and can guide the airflow flowing into the inner side of the connector side plate 410 towards the flow hole 411 on the opposite side, making it easier for the airflow to flow into the external air duct 102 through the flow hole 411.

[0187] Referring to Figures 9, 16, 20 and 21, preferably, the first electrical connector 600 and the pin 580 are both located at one end of the nozzle 10 along its own radial direction, and the flow hole 411 is located at the other end of the nozzle 10 along its own radial direction.

[0188] Specifically, the first electrical connector 600 and the pin 580 are both located at the front of the nozzle 10, and the flow hole 411 is located at the rear of the nozzle 10 (the front and rear parts are located on opposite sides of a plane passing through the central axis of the body 20 and parallel to the end face of the nozzle 10). This arrangement saves space and shortens the circuit connection path. At the same time, the design of front wiring and rear airflow makes the airflow smoother. Airflow enters the nozzle 10 from the rear and exits the nozzle 10 from the front. The flow hole 411 is located at the rear, far from the air outlet, providing a sufficiently long air duct for airflow deflection.

[0189] Referring to Figures 21 and 22, preferably, a support frame 111 is provided inside the accessory housing 100 to support the substrate 620, making the position of the substrate 620 more stable. Specifically, the support frame 111 is disposed inside the first housing portion 110.

[0190] Referring to Figures 17 and 22, in some embodiments, one of the outer sidewall of the air outlet sleeve 300 and the inner sidewall of the accessory housing 100 is provided with a guide rib 121 extending axially along the air outlet sleeve 300, and the other is provided with a first guide groove 321 extending axially along the air outlet sleeve 300. When the air outlet sleeve 300 is installed into the accessory housing 100, the guide rib 121 slides along the first guide groove 321.

[0191] Specifically, the first guide groove 321 is recessed into the outer wall of the air outlet sleeve 300, and the guide rib 121 protrudes from the inner wall of the accessory housing 100. More specifically, the first guide groove 321 is disposed on the outer wall of the fixing base 320, and the guide rib 121 is disposed on the inner wall of the second housing portion 120. By providing the mutually cooperating first guide groove 321 and guide rib 121, the air outlet sleeve 300 can be guided and limited when installed into the accessory housing 100, ensuring the axial alignment of the air outlet sleeve 300 and the accessory housing 100. In other embodiments, the positions of the first guide groove 321 and guide rib 121 can also be interchanged.

[0192] Referring to Figures 17 and 23, in some embodiments, one of the inner sidewall of the air outlet sleeve 300 and the outer sidewall of the functional component 500 is provided with a second guide groove 314 extending axially along the air outlet sleeve 300, and the other is provided with a guide plate 512 extending axially along the air outlet sleeve 300. When the functional component 500 enters the mounting cavity 101 axially along the air outlet sleeve 300, the guide plate 512 is inserted into the second guide groove 314.

[0193] Specifically, the second guide groove 314 is disposed on the inner side wall of the air outlet sleeve 300, and the guide plate 512 is disposed on the outer side wall of the functional component 500. By providing the mutually cooperating second guide groove 314 and guide plate 512, the functional component 500 can be guided and limited during installation, ensuring accurate installation. In other embodiments, the positions of the second guide groove 314 and guide plate 512 can be interchanged.

[0194] Referring to Figures 12, 16, 17 and 23, in some embodiments, the nozzle 10 includes a first electrical connector 600 for electrical connection with the body 20, and the functional component 500 includes a circuit board 540 and a pin 580. One end of the pin 580 is electrically connected to the circuit board 540, and the other end passes through the air outlet sleeve 300 and is electrically connected to the first electrical connector 600. The guide plate 512 and the second guide groove 314 are provided with two sets of matching pins 580, and the pin 580 is located between the two sets of guide plates 512.

[0195] Thus, the guide plate 512 not only guides the pin 580 but also protects it from damage. The structure of the pin 580, the structure of the first electrical connector 600, and the connection method between them have been described in the previous embodiments and will not be repeated here. It should be noted that the contact slot 311 mentioned in the previous embodiments does not penetrate radially into the air outlet sleeve 300 to prevent airflow leakage within the external air duct 102.

[0196] Referring to Figures 21, 23, and 24, in some embodiments, the functional component 500 is an essential oil atomizing component. The essential oil atomizing component includes an essential oil bottle 510 for storing essential oil, as well as a tungsten filament heating element 520, a flow guide rod 530, and a circuit board 540. The tungsten filament heating element 520 is electrically connected to the circuit board 540. The flow guide rod 530 extends into the essential oil bottle 510, and the tungsten filament heating element 520 is connected to the flow guide rod 530. The essential oil in the essential oil bottle 510 can be guided to the tungsten filament heating element 520 through the flow guide rod 530 and heated and atomized by the tungsten filament heating element 520.

[0197] Specifically, the tungsten filament heating element 520 is connected to the top of the guide rod 530. In the tungsten filament heating element 520, the tungsten filament is embedded in microporous ceramic and electrically connected to a circuit board 540, which controls the tungsten filament's operation. When the tungsten filament is energized, it heats and atomizes the essential oil adhering to the microporous ceramic, turning it into small particles that can be carried out by the airflow. The atomized essential oil adheres more easily to the hair surface, resulting in better conditioning effects. It should be noted that this atomization is not vaporization; the essential oil is atomized but not vaporized by controlling the tungsten filament temperature. In existing technologies, essential oils evaporate directly through openings; evaporation begins as soon as the package is opened and cannot be manually controlled. In the above embodiment, the circuit board 540 can control the energization and de-energization of the tungsten filament, allowing for atomization of the essential oil as needed, reducing waste.

[0198] In some embodiments, the circuit board 540 is also provided with an LED bead 541 electrically connected thereto. The LED bead 541 is covered with a semi-transparent lampshade 560. When the LED bead 541 emits light, it is diffused through the lampshade 560 and then transmitted, which can make the light uniformly diffused white light, which is softer, and only a small number of LED beads 541 are needed to achieve the aperture effect.

[0199] The essential oil atomizing assembly also includes components such as a diffuser mesh 570 and an oil-absorbing cotton 550. The diffuser mesh 570 is connected to the essential oil bottle 510 and is grid-shaped. The aforementioned fixing groove 571 is located on the outer wall of the diffuser mesh 570. The annular oil-absorbing cotton 550 is located inside the diffuser mesh 570 and on the side of the circuit board 540 opposite to the tungsten filament heating element 520, used to absorb essential oil that was not successfully atomized by the tungsten filament heating element 520. The annular lampshade 560 is located inside the diffuser mesh 570 and on the side of the oil-absorbing cotton 550 opposite to the circuit board 540. The atomized essential oil passes sequentially through the inner holes of the annular oil-absorbing cotton 550 and the lampshade 560. The airflow in the first space 1011 passes from the outside in through the side grid of the diverging mesh 570, reaching the space between it and the lampshade 560. It carries the atomized essential oil particles and is blown out through the end grid of the diverging mesh 570. Unatomized essential oil is absorbed by the inner wall of the oil-absorbing cotton 550 as it passes through the inner holes.

[0200] Preferably, the inner wall of the lampshade 560 is curved to facilitate the outflow of atomized essential oil particles.

[0201] Preferably, the distance between the end face of the lampshade 560 and the inner end face of the radiating mesh 570 is less than 5mm, so that the airflow reaching the first space 1011 can flow at high speed between the end face of the lampshade 560 and the inner end face of the radiating mesh 570, and blow out atomized essential oil particles.

[0202] When the essential oil atomizing component is not installed, the hair drying device can be used as a hair dryer without specific functions. Conversely, when the essential oil atomizing component is installed, the control board 832 inside the body 20 detects that the circuit board 540 of the essential oil atomizing component is in a conductive state. The tungsten filament heating element 520 heats the essential oil to atomize it, and the lamp bead 541 emits light. The heating wire 834 in the body 20 does not heat up to prevent the essential oil from vaporizing due to excessive temperature.

[0203] Referring to Figures 23 and 24, in some embodiments, the bottom wall of the essential oil bottle 510 is recessed inward to form a recess 513.

[0204] Specifically, during the molding process of the essential oil bottle 510, adhesive is injected through its bottom wall. Therefore, after molding, the bottom wall of the bottle will have a local outward bulge. By concave the bottom wall inward, it can prevent users from being uncomfortable to the touch by the local outward bulge structure on the bottom wall during disassembly and assembly. In addition, the aforementioned rear cover end plate 210 is also inclined and concave inward to prevent users from accidentally touching the bottom wall of the essential oil bottle 510 and pushing the entire component out of the mounting cavity 101.

[0205] Furthermore, in some embodiments, the inner side of the bottom wall of the essential oil bottle 510 is provided with a partial protrusion 514 that protrudes toward the guide rod 530. During use, the partial protrusion 514 allows the essential oil to more easily come into contact with the guide rod 530.

[0206] Referring to Figures 12, 16, 23 and 24, in some embodiments, the essential oil atomizing assembly includes a storage section for storing essential oil and an evaporation section for atomizing essential oil. The evaporation section forms a first portion 501, and the storage section forms a second portion 502. A circuit board 540 and a pin 580 are both disposed in the evaporation section. The evaporation section and the first electrical connector 600 are both located at the same end of the nozzle 10 along its own radial direction.

[0207] Since both the circuit board 540 and the pin 580 are located in the evaporation section, and both the evaporation section and the first electrical connector 600 are located at the same end of the nozzle 10 along its own radial direction, the circuit connection path is shorter when the pin 580 and the contact piece 640 in the first electrical connector 600 make contact and conduct. In addition, the storage section is designed with a slim shape, which can increase the space for storing essential oils and facilitate the dipping of the guide rod 530 into the essential oil.

[0208] Figures 26 to 35 are schematic diagrams of another nozzle provided in the embodiments of this application. Specifically, Figure 26 is a schematic diagram of the nozzle provided in the embodiments of this application; Figure 27 is a schematic diagram of the internal structure of the nozzle provided in the embodiments of this application; Figure 28 is a schematic diagram of the nozzle in the smoothed state provided in the embodiments of this application; and Figure 29 is a schematic diagram of the nozzle in the direct blowing state provided in the embodiments of this application.

[0209] Referring to Figures 26, 27, 28, and 29, the nozzle 10-100 provided in this embodiment of the application includes a housing 10-10 and a switching component 10-50.

[0210] The housing 10-10 has an air outlet 10-11 and an air inlet 10-12 on its surface, and a first air duct 10-20 and a second air duct 10-30 are formed inside the housing 10-10. The first outlet 10-21 of the first air duct 10-20 and the second outlet 10-31 of the second air duct 10-30 are both connected to the air outlet 10-11, and the first inlet 10-22 of the first air duct 10-20 and the second inlet 10-32 of the second air duct 10-30 are both arranged adjacent to the air inlet 10-12. A switching element 10-50 is rotatably connected to the housing 10-10 about an axis, and the switching element 10-50 is configured to selectively close the first inlet 10-22 and the second inlet 10-32 when rotated.

[0211] In this configuration, the width of both the first air duct 10-20 and the second air duct 10-30 along the first direction F is greater than the opening size of the air inlet 10-12 along the first direction F. The air inlet 10-12 supplies air to a position between the two ends of at least one of the first inlet 10-22 and the second inlet 10-32 along the first direction F. For example, the width of the first air duct 10-20 along the first direction F can be the width of the section of the first air duct 10-20 immediately adjacent to the first inlet 10-22 along the first direction F. The width of the second air duct 10-30 along the first direction F refers to the width of the section of the second air duct 10-30 immediately adjacent to the second inlet 10-32 along the first direction F.

[0212] In this embodiment, the first inlet 10-22, the second inlet 10-32, and the air inlet 10-12 are arranged adjacent to each other and all have a certain size in the first direction F. The first direction F may, for example, be parallel to the rotation axis of the switching member 10-50. Exemplarily, the first inlet 10-22 and the second inlet 10-22 may also be elongated inlets extending along the rotation axis of the switching member 10-50.

[0213] In addition, for ease of explanation, the air intake direction of the air inlet 10-12 is defined as the second direction S, which is also the height direction of the air duct body 10-40.

[0214] By providing a first air duct 10-20, a second air duct 10-30, and a switching element 10-50 within the housing 10-10, the switching element 10-50 is rotatably connected within the housing 10-10 around an axis. The switching element 10-50 is configured to selectively close the first inlet 10-22 and the second inlet 10-32 when rotated. By rotating the switching element 10-50 and closing the first inlet 10-22, the air from the air inlet 10-12 can enter the second air duct 10-30 through the second inlet 10-32 and flow out through the second outlet 10-31 and the air outlet 10-11. By simply rotating the switching component 10-50 and closing the second inlet 10-32, the air from the air inlet 10-12 can enter the first air duct 10-20 through the first inlet 10-22 and flow out through the first outlet 10-21 and the air outlet 10-11. Thus, the switching of the two air ducts can be achieved with a relatively simple switching structure.

[0215] Since the width of the first air duct 10-20 and the second air duct 10-30 along the first direction F is greater than the opening size of the air inlet 10-12 along the first direction F, in other words, the opening size of the first inlet 10-22 and the second inlet 10-32 along the first direction F is greater than the opening size of the air inlet 10-12 along the first direction F, when the air inlet 10-12 intakes air into the first inlet 10-22 or the end position of the second inlet 10-32 along the first direction F, taking the air intake position of the air inlet 10-12 located at the end position of the first inlet 10-22 as an example, due to wind resistance, the air intake volume at the position farther away from the end position in the first inlet 10-22 will gradually decrease, which also leads to the air volume along the first direction F in the first outlet 10-21 being very uneven.

[0216] In this application, the air inlet 10-12 introduces air at a position between the two ends of at least one of the first inlet 10-22 and the second inlet 10-32 along the first direction F. Compared to the air inlet position being at any end along the first direction F (the end includes at least one of the upper, lower, front, rear, side, and / or circumferential surfaces of any end along the first direction F), the distance between the air inlet position and the two ends of the first inlet 10-22 is reduced. The attenuation of the airflow from the air inlet position to the two ends of the first inlet 10-22 is not as significant as when the air inlet 10-12 is at the end. In other words, compared to the air inlet position being between the two ends, the airflow entering from the first inlet 10-22 is relatively more uniform along the first direction F, thus improving the uniformity of the airflow along the first direction F in the first outlet 10-21 to a certain extent. The case where the air inlet 10-12 introduces air at a position between the two ends of the second inlet 10-32 along the first direction F is similar and will not be described further here.

[0217] In this embodiment of the application, the first air duct 10-20 includes a first main air duct 10-23 and a first extended air duct 10-24 connected together; the second air duct 10-30 includes a second main air duct 10-33 and a second extended air duct 10-34 connected together.

[0218] The nozzle 10-100 also includes an air duct body 10-40 disposed on the inner wall of the housing 10-10. A first main air duct 10-23 and a second main air duct 10-33 are formed in layers along a second direction S within the air duct body 10-40. The outlets of the first main air duct 10-23 and the second main air duct 10-33 respectively form a first outlet 10-21 and a second outlet 10-31. The first direction F is perpendicular to the second direction S. A portion of the second main air duct 10-33 near its outlet bends in a direction away from the first main air duct 10-23.

[0219] This configuration, by forming the first main air duct 10-23 and the second main air duct 10-33 near the air outlet 10-11 of the first air duct 10-20 and the second air duct 10-30 into a single air duct body 10-40, allows for flexible adjustment of the shapes of the first main air duct 10-23 and the second main air duct 10-33 according to actual usage. The section of the second main air duct 10-33 near its outlet bends away from the first main air duct 10-23, giving the airflow from the second main air duct 10-33 a smoothing effect. Conversely, if the section of the first main air duct 10-23 near its outlet is set to a straight section, the airflow from the first main air duct 10-23 will have a direct blowing effect.

[0220] It is understandable that in some other embodiments, the section of the first main air duct 10-23 near its own outlet may be bent in a direction away from the second main air duct 10-33, which can give the air blown out of the first main air duct 10-23 a smoothing effect. Of course, the section of the second main air duct 10-33 near its own outlet may be set as a straight section, so that the air blown out of the second main air duct 10-33 can have a direct blowing effect.

[0221] In this embodiment of the application, there are multiple first main air ducts 10-23, and the multiple first main air ducts 10-23 are arranged in a row along the first direction F. There are multiple second main air ducts 10-33, and the second main air ducts 10-33 are arranged in a row along the first direction F.

[0222] With this setup, under the same air intake volume, the airflow velocity in each main air duct is faster and more uniform, thus enhancing the blowing effect.

[0223] In this embodiment of the application, referring to FIG27, the air inlet 10-12 introduces air into the central position of the first inlet 10-22 and the second inlet 10-32 along the first direction F.

[0224] Figure 30 is a schematic diagram of the air duct body in the nozzle provided in the embodiment of this application.

[0225] Referring to Figure 30, the opening area of ​​the inlet 10-231 of each first main air duct is configured to gradually increase in the order from the center position of the first direction F to the two ends of the first direction F.

[0226] Furthermore, the opening area of ​​the inlet 10-331 of each of the second main air ducts is configured to gradually increase in the order from the center position of the first direction F to the two ends of the first direction F.

[0227] Similarly, the further away from the center, the greater the wind resistance and the smaller the air intake. However, the above settings can compensate for the attenuation of air intake near the ends of the duct body (10-40), making the air intake more balanced throughout the entire area in the first direction F.

[0228] In practice, the opening size of the inlet 10-231 of each first main air duct along the first direction F is configured to gradually increase in the order from the center position of the first direction F to the two ends of the first direction F.

[0229] Furthermore, the opening size of the inlet 10-331 of each of the second main air ducts along the first direction F is configured to gradually increase in the order from the center position of the first direction F to the two ends of the first direction F.

[0230] In some embodiments, the opening size of the inlet 10-231 of each first main air duct along the second direction S is configured to gradually increase in size from the center position of the first direction F to the two ends of the first direction F. In some embodiments, the second direction S is perpendicular to the first direction, and the second direction S is also the height direction of the air duct body 10-40.

[0231] Furthermore, the opening size of the inlet 10-331 of each second main air duct along the second direction S is configured to gradually increase in the order from the center position of the first direction F to the two ends of the first direction F.

[0232] In this embodiment of the application, the air duct 10-40 includes a body 10-41 and a wind baffle 10-42;

[0233] Each first main air duct 10-23 and each second main air duct 10-33 are formed in the body 10-41, and the wind baffle 10-42 is provided with a plurality of first air holes 10-421 and a plurality of second air holes 10-422.

[0234] The first air vent 10-421 is connected to each of the first main air ducts 10-23 in a one-to-one correspondence, and the first air vent 10-421 forms the entrance 10-231 of the first main air duct. The second air vent 10-422 is connected to each of the second main air ducts 10-33 in a one-to-one correspondence, and the second air vent 10-422 forms the entrance 10-331 of the second main air duct.

[0235] With this configuration, even when the inlet sizes 10-231 of each first main air duct are different, the channel dimensions of each first main air duct 10-23 can be the same; only the dimensions of the first air holes 10-421 on the baffle plate 10-42 need to be different. Similarly, even when the inlet sizes 10-231 of each first main air duct are different, the channel dimensions of each second main air duct 10-33 can be the same; only the dimensions of the second air holes 10-422 on the baffle plate 10-42 need to be different. This simplifies the main body's manufacturing process.

[0236] In this embodiment of the application, referring to Figures 27 and 28, the inner wall of the housing 10-10 is provided with two baffles 10-14, which are arranged opposite to each other along the second direction S.

[0237] Both baffles 10-14 are positioned on the side of the air duct body 10-40 opposite to the air outlet 10-11 to fix the air duct body 10-40 inside the housing 10-10.

[0238] This configuration allows for the fixation of the air duct body 10-40 with a simple structure. The air duct body 10-40 can extend along the first direction F.

[0239] Referring again to Figure 26, the air outlet 10-11 includes a first sub-air outlet 10-111 and a second sub-air outlet 10-112. The first sub-air outlet 10-111 is connected to the outlet of each of the first main air ducts 10-23, and the second sub-air outlet 10-112 is connected to the outlet of each of the second main air ducts 10-33. In other words, the first sub-air outlet 10-111 is arranged correspondingly to the first main air duct 10-23, and the second sub-air outlet 10-112 is arranged correspondingly to the second main air duct 10-33. Both the first sub-air outlet 10-111 and the second sub-air outlet 10-112 extend along the first direction F, and are spaced apart along the second direction S.

[0240] In this embodiment of the application, referring to Figures 28, 30, and 31, the switching component 10-50 includes a switching shaft 10-51 and a switching plate 10-52 connected to the circumferential surface of the switching shaft 10-51. The switching shaft 10-51 is rotatably connected to the inner wall of the housing 10-10 about the aforementioned axis.

[0241] The surface of the air duct body 10-40 is also provided with a partition 10-43, which is located between the inlet 10-231 of the first main air duct and the inlet 10-331 of the second main air duct, and abuts against the circumferential surface of the switching shaft 10-51.

[0242] The air duct body 10-40, the switching shaft 10-51, and the inner wall of the housing 10-10 together define an annular channel H. In the annular channel H, at least a portion of the channel between one surface of the partition 10-43 (e.g., the upper surface in Figure 28) and the air inlet 10-12 forms a first extended air duct 10-24. At least a portion of the channel between the other surface of the partition 10-43 (e.g., the lower surface in Figure 28) and the air inlet 10-12 forms a second extended air duct 10-34.

[0243] With this configuration, a portion of the annular channel H defined within the housing 10-10 by the switching shaft 10-51 and the partition 10-43 is respectively used as the first extended air duct 10-24 and the second extended air duct 10-34. This eliminates the need to install components with internal channels (such as the air duct body 10-40) within the housing 10-10, resulting in a more compact internal structure and fewer components within the housing 10-10.

[0244] The partition 10-43 can be fixed to the baffle 10-42 of the air duct body 10-40, or the partition 10-43 and the baffle 10-42 can be integrally formed. Specifically, the partition 10-43 is fixed or formed on the side of the baffle 10-42 away from the body 10-41 and extends toward the switching shaft 10-51. The end of the partition 10-43 near the switching shaft 10-51 is designed to fit the circumferential surface of the switching shaft 10-51 and is adapted to the rotation of the switching element 10-50.

[0245] In a specific implementation, for example, a pad 10-431 can be provided at the end of the partition 10-43, and the contour shape of the side surface of the pad 10-431 facing the switching shaft 10-51 matches the outer peripheral surface of the switching shaft 10-51.

[0246] In this way, when the partition 10-43 abuts against the switching shaft 10-51, it will not obstruct or affect the rotation of the switching shaft 10-51, and will also increase the sealing between the first extension channel and the second extension channel. Of course, the gasket 10-431 is set with appropriate dimensions to allow for the smooth rotation of the switching component 10-50.

[0247] Referring again to Figures 27 and 28, the inner wall of the housing 10-10 is provided with a first baffle wall 10-13, and the air duct body 10-40 is provided with a second baffle wall 10-44. The air inlet 10-12 is located between the first baffle wall 10-13 and the second baffle wall 10-44. The first baffle wall 10-13 defines a first inlet 10-22, and the second baffle wall 10-44 defines a second inlet 10-32.

[0248] As previously described, the air duct body 10-40, the switching shaft 10-51, and the inner wall of the housing 10-10 together define an annular channel H. In the annular channel H, a portion of the channel serves as a first extended air duct 10-24, and a portion serves as a second extended air duct 10-34. In the annular channel H, the portion of the channel between one surface of the partition 10-43 (e.g., the upper surface in Figure 28) and the first baffle wall 10-13 forms the first extended air duct 10-24. At least a portion of the channel between the other surface of the partition 10-43 (e.g., the lower surface in Figure 28) and the second baffle wall 10-44 forms the second extended air duct 10-34. The portion formed between the first baffle wall 10-13 and the second baffle wall 10-44 communicates with the air inlet 10-12. In other words, the air entering through the air inlet 10-12 passes through the area between the first baffle wall 10-13 and the second baffle wall 10-44, and then either enters the first inlet 10-22 or the second inlet 10-32.

[0249] When the switching plate 10-52 rotates around its axis, it abuts against the first stop wall 10-13 and the second stop wall 10-44 respectively. When the switching plate 10-52 abuts against the first stop wall 10-13, the first inlet 10-22 is closed. When the switching plate 10-52 abuts against the second stop wall 10-44, the second inlet 10-32 is closed.

[0250] Since the air inlet 10-12 is located between the first baffle wall 10-13 and the second baffle wall 10-44, the first baffle wall 10-13 is located in the channel section between one surface of the partition 10-43 and the air inlet 10-12, and the second baffle wall 10-44 is located in the channel section between the other surface of the partition 10-43 and the air inlet 10-12. The cooperation between the switching plate 10-52 and the first baffle wall 10-13 and the second baffle wall 10-44 forms a first inlet 10-22 in the first baffle wall 10-13 and a second inlet 10-32 in the second baffle wall 10-44.

[0251] In this embodiment of the application, referring to FIG27, the air inlet 10-12 is opened on the bottom wall of the housing 10-10, and the switching shaft 10-51 is arranged inside the housing 10-10 at a certain distance from the bottom wall of the housing 10-10. In this way, the air inlet 10-12 and the switching shaft 10-51 are arranged at intervals along the second direction S, and the air inlet 10-12 and the switching shaft 10-51 are both located on the same side of the air duct body 10-40. The distance between the air inlet 10-12 and the inlet 10-331 of the second main air duct is less than the distance between the air inlet 10-12 and the inlet 10-231 of the first main air duct.

[0252] With this configuration, the air intake from the air inlet 10-12 can directly enter the inlet 10-331 of the second main air duct when the second inlet 10-32 is opened. The first extended air duct 10-24 is formed into a bent shape, so that the first inlet 10-22 and the second inlet 10-32 can be arranged relative to each other.

[0253] Figure 31 is an exploded view of the switching shaft and housing mounting structure in the nozzle provided in the embodiment of this application.

[0254] In this embodiment of the application, referring to FIG31, the inner wall of the housing 10-10 is further provided with a first mounting groove 10-5311, and at least a portion of the structure of the partition 10-43 is inserted into the first mounting groove 10-5311. In this way, the first mounting groove 10-5311 can provide auxiliary positioning for the partition 10-43.

[0255] In this embodiment of the application, referring to Figures 26 and 31, the housing 10-10 includes a first sidewall 10-15 and a second sidewall 10-16 disposed opposite to each other along a first direction F; the first end of the switching shaft 10-51 is rotatably connected to the first sidewall 10-15, and the second end of the switching shaft 10-51 is rotatably connected to the second sidewall 10-16. With this configuration, the switching shaft 10-51 can be mounted inside the housing 10-10 along the first direction F.

[0256] In this embodiment, the first sidewall 10-15 has a second mounting groove 10-151, and the inner wall of the second mounting groove 10-151 has multiple protruding ribs 10-152, which form a circle around the aforementioned axis. One end of the switching shaft 10-51, i.e., the first end of the switching shaft 10-51, is inserted into the second mounting groove 10-151 and abuts against each of the protruding ribs 10-152. This arrangement ultimately allows each protruding rib 10-152 to support the first end of the switching shaft 10-51. When the switching shaft 10-51 rotates relative to the first sidewall 10-15, the contact area is reduced, thus reducing friction.

[0257] In this embodiment, a portion of the second mounting groove 10-151 is provided with a clearance opening 10-1511 to allow for the rotational movement of the switching plate 10-52. When the switching plate 10-52 abuts against the first stop wall 10-13, the switching plate 10-52 abuts against one edge of the clearance opening 10-1511. When the switching plate 10-52 abuts against the second stop wall 10-44, the switching plate 10-52 abuts against the other edge of the clearance opening 10-1511. This arrangement allows the two edges of the clearance opening 10-1511 to limit the movement of the switching plate 10-52.

[0258] Figure 32 is an exploded structural diagram of the nozzle provided in an embodiment of this application.

[0259] In this embodiment of the application, referring to FIG32, a decorative cover 10-1501 is also installed on the side of the first sidewall 10-15 opposite to the second sidewall 10-16. In order to facilitate observation of the internal structure, part of the structure of the housing 10-10 is hidden, leaving only the second sidewall 10-16. The nozzle 10-100 also includes an operating component 10-60, which includes a knob 10-61. The switching component 10-50 also includes a transmission disk 10-53, which is connected to the other end of the switching shaft 10-51, that is, the second end of the switching shaft 10-51. The transmission disk 10-53 is rotatably connected to the second sidewall 10-16 so that the other end of the switching shaft 10-51 is rotatably connected to the second sidewall 10-16.

[0260] The transmission disc 10-53 has a first mating part 10-531 on the side opposite to the switching shaft 10-51. The first mating part 10-531 passes through the second side wall 10-16 and extends out of the housing 10-10. For example, a mounting hole 10-161 can be provided on the second side wall 10-16 for the first mating part 10-531 to pass through. The knob 10-61 is located outside the housing 10-10 and is connected to the first mating part 10-531 of the transmission disc 10-53.

[0261] By rotating the knob 10-61, the transmission disc 10-53 and the switching shaft 10-51 can be driven to rotate together.

[0262] In this embodiment of the application, referring to FIG32, the knob 10-61 is flipped to the other side and exposed, as shown by the black arrow. The surface of the knob 10-61 facing the transmission disk 10-53 is provided with a second mating part 10-611. The top surface of the second mating part 10-611 is provided with a groove 10-5311, and the first mating part 10-531 is fitted in this groove 10-5311.

[0263] In practice, the number of the second mating parts 10-611 and the first mating parts 10-531 are both multiple and arranged in a one-to-one correspondence. For example, the number of the first mating parts 10-531 and the second mating parts 10-611 can both be 10-4 sets. The knob 10-61 can be rotated relative to the second side wall 10-16 by snapping it onto the transmission disk 10-53.

[0264] In this embodiment of the application, the knob 10-61 is provided with an opening 10-612 to expose part of the structure of the transmission disk 10-53. The operating component 10-60 also includes a knob cover 10-62, which is snapped onto the knob 10-61 and seals the opening 10-612.

[0265] In this embodiment, a stepped portion 10-532 is formed on the circumferential surface of the transmission disk 10-53, and a mounting hole 10-161 is formed on the second sidewall 10-16. A circumferential protrusion is provided on the inner edge of the mounting hole 10-161, and the protrusion abuts against the stepped portion 10-532 so that the transmission disk 10-53 is rotatably connected to the second sidewall 10-16.

[0266] This configuration facilitates the positioning of the switching shaft 10-51 and the second side wall 10-16 along the axial direction of the switching shaft 10-51. Additionally, the second side wall 10-16 can be formed separately from the main body 10-101 of the housing 10-10, in which case the second side wall 10-16 can be snapped onto the main body 10-101 of the housing 10-10.

[0267] Referring to Figures 26, 31, and 32, as previously described, the housing 10-10 may include a main body 10-101, a first sidewall 10-15, and a second sidewall 10-16. The main body 10-101 is constructed as a hollow component with openings at both ends. The first sidewall 10-15 and the second sidewall 10-16 are respectively connected to both sides of the main body 10-101 along the first direction F. A decorative cover 10-1501 is connected to the end of the first sidewall 10-15 facing away from the second sidewall 10-16.

[0268] Figure 33 is a schematic diagram of the structure of the operating component in the smoothing state of the nozzle provided in the embodiment of this application, and Figure 34 is a schematic diagram of the structure of the operating component in the direct blowing state of the nozzle provided in the embodiment of this application.

[0269] The state in Figure 33 corresponds to that in Figure 28, and the state in Figure 34 corresponds to that in Figure 29. For ease of observation, in both Figure 33 and Figure 34, the transmission disc 10-53 is moved a certain distance away from the inner liner cover 10-17 along the axial direction of the switching shaft 10-51.

[0270] In this embodiment of the application, referring to Figures 28, 29, 33, and 34, the housing 10-10 also includes an inner liner 10-17, which is connected inside the housing 10-10. The switching shaft 10-51 passes through the inner liner 10-17, and the inner liner 10-17 is also arranged opposite to the transmission disc 10-53.

[0271] The transmission disc 10-53 drives the switching shaft 10-51 to rotate. The transmission disc 10-53 has three rotational positions relative to the inner liner cover 10-17: a first position as shown in Figures 28 and 33, a second position as shown in Figures 29 and 34, and a third position. After rotating a certain angle counterclockwise or clockwise relative to the inner liner cover 10-17 from the third position, the transmission disc 10-53 rotates to the first and second positions respectively. Alternatively, the third position can be the central position between the first and second positions; that is, after rotating the transmission disc 10-53 counterclockwise or clockwise relative to the inner liner cover 10-17 by the same angle from the third position, it rotates to the first and second positions respectively.

[0272] When the transmission disc 10-53 is in the first position, the switching plate 10-52 closes the first inlet 10-22. When the transmission disc 10-53 rotates to the second position, the switching plate 10-52 closes the second inlet 10-32.

[0273] The operating assembly 10-60 also includes an elastic element 10-80, which is connected to the transmission disk 10-53 and the inner liner cover 10-17 respectively. The elastic element 10-80 is used to apply a clockwise torque to the rotating disk when the transmission disk 10-53 is between the first position and the third position. The elastic element 10-80 is also used to apply a counterclockwise torque to the rotating disk when the transmission disk 10-53 is between the second position and the third position.

[0274] With this configuration, during switching, when the operator manually operates the knob 10-61 to rotate the transmission disc 10-53, if the disc is between the first and third positions, and the operator does not operate the knob 10-61, the transmission disc 10-53 will switch to the first position under the clockwise torque of the elastic element 10-80. Since the switching plate 10-52 is blocked on the first stop wall 10-13 at this time, even if the operator stops operating, the transmission disc 10-53 will always stay in the first position under the clockwise torque, keeping the first inlet 10-22 closed. Similarly, if the operator manually operates knob 10-61 to rotate transmission disc 10-53, and the disc is between the second and third positions, then if the operator does not operate knob 10-61, transmission disc 10-53 will switch to the second position under the counterclockwise torque of elastic element 10-80. Since switching plate 10-52 is blocked on the second stop wall 10-44 at this time, even if the operator stops operating, transmission disc 10-53 will always stay in the second position under the counterclockwise torque, keeping the second inlet 10-32 closed.

[0275] In this embodiment, when the movement of the transmission disc 10-43 is directed to the switching member 10-50, the switching member 10-50 has a first rotational position, a second rotational position, and a third rotational position relative to the inner liner cover 10-17. The first rotational position of the switching member 10-50 corresponds to the first position of the transmission disc 10-53, the second rotational position of the switching member 10-50 corresponds to the second position of the transmission disc 10-53, and the third rotational position of the switching member 10-50 corresponds to the third position of the transmission disc 10-53.

[0276] Based on this, the switching element 10-50 closes the first inlet 10-22 when in the first rotation position, and the switching element 10-50 closes the second inlet 10-32 when in the second rotation position.

[0277] The elastic element 10-80 is used to apply a clockwise torque to the switching element 10-50 when the switching element 10-50 is between the first rotation position and the third rotation position. The elastic element 10-80 is also used to apply a counterclockwise torque to the switching element 10-50 when the switching element 10-50 is between the second rotation position and the third rotation position.

[0278] With this configuration, during switching, when the switching element 10-50 is between the first and third rotational positions, it will switch to the first rotational position under the clockwise torque of the elastic element 10-80, closing the first inlet 10-22. Similarly, when the switching element 10-50 is between the second and third rotational positions, it will switch to the second rotational position under the counterclockwise torque of the elastic element 10-80, closing the second inlet 10-32. The switching and locking of the switching element 10-50 between the first and second rotational positions can be accomplished solely by the elastic element 10-80, resulting in a simple structure and relatively easy operation.

[0279] In this embodiment of the application, referring to FIG34, the elastic element 10-80 is a torsion spring, which includes a torsion spring body 10-801, a first connecting arm 10-81 and a second connecting arm 10-82.

[0280] The first connecting arm 10-81 and the second connecting arm 10-82 extend radially outward from the end of the torsion spring body 10-801, and the first connecting arm 10-81 and the second connecting arm 10-82 have a preset included angle. The first connecting arm 10-81 is connected to the inner liner cover 10-17, and the second connecting arm 10-82 is connected to the transmission disc 10-53.

[0281] Thus, the elastic element 10-80 can apply an elastic force toward the first position to the transmission disk 10-53 when the transmission disk 10-53 is between the first position and the third position, and apply an elastic force toward the second position to the transmission disk 10-53 when the transmission disk 10-53 is between the second position and the third position.

[0282] In this embodiment of the application, referring to FIG34, the ends of the first connecting arm 10-81 and the second connecting arm 10-82 are respectively provided with a first mounting ring 10-811 and a second mounting ring 10-821. The inner liner cover 10-17 and the transmission disk 10-53 are respectively provided with a first mounting post 10-171 and a second mounting post 10-533 on their opposing surfaces, and the first mounting post 10-171 and the second mounting post 10-533 are respectively disposed at different positions in the radial direction of the switching shaft 10-51.

[0283] The first mounting ring 10-811 is mounted on the first mounting post 10-171, and the second mounting ring 10-821 is mounted on the second mounting post 10-533. It should be noted that in Figure 34, for ease of observation, the transmission disc 10-53 has been moved a certain distance away from the inner liner cover 10-17, and the second mounting ring 10-821 and the second mounting post 10-533 are in a disengaged state.

[0284] This configuration allows the first connecting arm 10-81 and the second connecting arm 10-82 of the torsion spring to be reliably mounted on the inner liner cover 10-17 and the transmission disc 10-53, respectively.

[0285] In this embodiment, a sliding groove 10-534 is formed on the surface of the inner liner 10-17 facing the transmission disk 10-53. When the transmission disk 10-53 rotates, the second mounting post 10-533 slides within the sliding groove 10-534. The sliding groove 10-534 has a first side groove wall 10-5341 and a second side groove wall 10-5342 that are oppositely disposed along the sliding direction.

[0286] When the transmission disc 10-53 rotates to the first position, the second mounting post 10-533 abuts against the first side groove wall 10-5341; when the transmission disc 10-53 rotates to the second position, the second mounting post 10-533 abuts against the second side groove wall 10-5342.

[0287] This configuration allows the rotation of the transmission disc 10-53 to be limited by the second mounting post 10-533 when the transmission disc 10-53 rotates.

[0288] Figure 35 is a schematic diagram of the structure of the inner liner and the transmission disc cooperating with each other in the nozzle provided in the embodiment of this application.

[0289] Referring to Figure 35, for easier observation, the transmission disk 10-53 is cut in half, and the outer contour of the transmission disk 10-53 is shown with dashed lines.

[0290] In this embodiment of the application, a first limiting part 10-172 and a second limiting part 10-535 are respectively provided on the opposing surfaces of the inner liner cover 10-17 and the transmission disk 10-53.

[0291] There are two first limiting parts 10-172 and one second limiting part 10-535. When the switching shaft 10-51 rotates around the axis, the second limiting part 10-535 abuts against the two first limiting parts 10-172 respectively.

[0292] When the second limiting part 10-535 abuts against one of the first limiting parts 10-172, the transmission disk 10-53 is in the first position; when the second limiting part 10-535 abuts against the other first limiting part, the transmission disk 10-53 is in the second position. In this way, the rotation of the transmission disk 10-53 between the first and second positions can be limited.

[0293] Furthermore, the inner liner 10-17 is connected to one end of the air duct body 10-40 along the first direction F, and part of the structure of the air duct body 10-40 is inserted into the inner liner 10-17.

[0294] In a specific connection, the connection between the air duct body 10-40 and the inner liner cover 10-17 can be made by fasteners such as screws.

[0295] Furthermore, a sealing ring 10-90 is connected between the inner liner cover 10-17 and the inner sidewall of the housing 10-10.

[0296] With this configuration, when the second sidewall 10-16 and the main body 10-41 are detachable, air leakage in the first extended air duct 10-24 and the second extended air duct 10-34 can be prevented.

[0297] The following description, in conjunction with Figures 28, 29, 32, 33, and 34, illustrates the switching process between the direct blowing and smoothing states of the nozzle 10-100 in this embodiment of the application.

[0298] In the states shown in Figures 28 and 32, the switching plate 10-52 abuts against the first stop wall 10-52, closing the first inlet 10-22. As indicated by the dashed arrows, the air intake from the air inlet 10-12 passes through the second extended air duct 10-34, the second main air duct 10-33, and flows out through the air outlet 10-11. Because a section of the second main air duct 10-33 bends downward near the outlet, the air blown out through the second main air duct 10-33 has a smoothing effect. In this state, referring to Figure 33, the transmission plate 10-53 is in the first position.

[0299] When the operator needs to switch to direct-blowing mode, they manually operate knob 10-61 to rotate the transmission disc 10-53 counterclockwise. Before the transmission disc 10-53 reaches the third position, the first mounting ring 10-811 and the second mounting ring 10-821 of the elastic element 10-80 move closer together, reducing the included angle. This ensures that the elastic element 10-80 consistently applies a clockwise torque to the transmission disc 10-53. The operator needs to overcome this torque and continue rotating the transmission disc 10-53 counterclockwise until it reaches the third position, which serves as the center position. At this point, the transmission disc 10-53 rotates from the third position to the second position, and the first mounting ring 10-811 and the second mounting ring 10-821 of the elastic element 10-80 move further apart, increasing the included angle. During this time, the elastic element 10-80 consistently applies a counterclockwise torque to the transmission disc 10-53. Even if the operator does not operate knob 10-61, the transmission disc will switch transmission disc 10-53 to the second position shown in Figures 29 and 34 under the action of the counterclockwise torque.

[0300] When the transmission disc 10-53 is in the second position, referring to Figure 29, the switching plate 10-52 abuts against the second stop wall 10-44, closing the second inlet 10-32. As shown by the dashed arrow, the air intake from the air inlet 10-12 passes through the first extended air duct 10-24, the first main air duct 10-23, and flows out through the air outlet 10-11. Since the first main air duct 10-23 is a straight channel near the outlet, the air blown out through the first main air duct 10-23 has a direct blowing effect.

[0301] When the operator needs to switch to the smoothing mode, they manually operate knob 10-61 to rotate the transmission disc 10-53 clockwise. Before the transmission disc 10-53 reaches the third position, the first mounting ring 10-811 and the second mounting ring 10-821 of the elastic element 10-80 move closer together, reducing the included angle. This ensures that the elastic element 10-80 consistently applies a counter-clockwise torque to the transmission disc 10-53. The operator must overcome this torque and continue rotating the transmission disc 10-53 clockwise until it reaches the third position, which serves as the center position. At this point, the transmission disc 10-53 rotates from the third position to the first position, and the first mounting ring 10-811 and the second mounting ring 10-821 of the elastic element 10-80 move further apart, increasing the included angle. During this time, the elastic element 10-80 consistently applies a clockwise torque to the transmission disc 10-53. Even if the operator does not operate knob 10-61, the transmission disc will switch transmission disc 10-53 to the first position shown in Figures 28 and 33 under the action of the clockwise torque.

[0302] This application also provides a hair care device, including the aforementioned nozzle 10-100. The structure, function, and working principle of the nozzle 10-100 have been described in detail above and will not be repeated here.

[0303] Referring to Figures 1, 3, and 25, in some embodiments, a hair care appliance provided in one embodiment of this application includes a body 20 and at least one nozzle 10. The body 20 includes a control board 832, a motor 833 electrically connected thereto, and a first circuit module. The body 20 has an air inlet 811 and an air outlet 812. The motor 833 is used to allow external airflow to flow into the body through the air inlet 811.

[0304] The air flows through the air outlet 812 and exits the body 20. The air nozzle 10 is detachably connected to the body 20 and includes a second circuit module. The air nozzle 10 receives the airflow exiting the air outlet 812, processes the received airflow, and then discharges it. The first circuit module can form a path independently, and the first circuit module can also form a path together with the second circuit module. The control board 832 can detect the path to determine the installation status and / or type of the air nozzle 10.

[0305] In the above embodiment, the motor 833 causes external airflow to flow into the body 20 through the air inlet 811 and exit the body 20 through the air outlet 812. The airflow exiting the body 20 flows into the nozzle 10, is processed, and then discharged, thereby providing corresponding hair care. The nozzle 10 is detachably connected to the body 20, so different types of hair care can be performed by changing the nozzle 10. The first circuit module can form a path independently, and the first circuit module can also form a path together with the second circuit module. It can be understood that when different nozzles 10 are installed on the body 20, the paths formed by the first circuit module and the corresponding second circuit module will also be different. Therefore, the control board 832 only needs to detect the path to determine the installation status and / or type of the nozzle 10, for example, to determine whether there is a nozzle 10 currently installed on the body 20, and the specific type of the installed nozzle 10. In the above identification process, only the first circuit module and the second circuit module need to be set up, and the type of the formed path is detected by the control board 832. There is no need to set up a complex mechanical docking structure. Therefore, the requirements for structural design are low, and there is no need to rely on sensors. Therefore, the identification results are more reliable.

[0306] As mentioned earlier, the nozzle 10 includes a functional component 500. When airflow passes through the nozzle 10, the functional component 500 processes the airflow accordingly. When different nozzles 10 are installed, the functional component 500 is different, thus enabling various different processing of the airflow. For example, the blown airflow can carry atomized essential oils, negative ions, water ions, etc.

[0307] Referring to Figures 1, 3 and 25, in some embodiments, the control panel 832 can control the hair care appliance to switch to the corresponding working mode based on the installation status and type of the nozzle 10.

[0308] Specifically, based on the type of functional components 500 in each nozzle 10, corresponding working modes can be set for the hair care device. For example, essential oil mode, negative ion mode, water ion mode, etc. Each mode is customized for the characteristics of the corresponding functional component 500, with optimal airflow speed and temperature, allowing the functional component 500 in that mode to achieve its best effect and provide better hair care. For example, in essential oil mode, the airflow temperature should not be too high to prevent the essential oil from vaporizing.

[0309] Referring to Figures 1, 3 and 25, further, in some embodiments, the body 20 includes a heating wire 834 electrically connected to a control board 832, which can control the power of the heating wire 834 and the motor 833 based on the installation status and type of the nozzle 10.

[0310] Specifically, when the nozzle 10 is not installed, or when different nozzles 10 are installed, the control board 832 can control the power of the motor 833 and heating wire 834 in the body 20 to switch to the corresponding working mode.

[0311] As mentioned earlier, each mode is customized for the characteristics of the corresponding functional component 500, with optimal wind speed and temperature. The wind speed can be controlled by adjusting the power of the motor 833, and the wind temperature can be controlled by adjusting the power of the heating wire 834. For example, increasing the power of the motor 833 increases the wind speed; adjusting the heating power of the heating wire 834 produces cool, warm, or hot air, or alternating hot and cold air.

[0312] In one specific embodiment, when the functional component 500 in the nozzle 10 is an essential oil atomizing component, the power of the heating wire 834 is 0, that is, the heating wire 834 does not work, so as to prevent the essential oil from vaporizing due to excessive temperature.

[0313] Referring to Figures 1, 3 and 25, in some embodiments, the control board 832 determines the installation status and type of the nozzle 10 by detecting the voltage of the detection path.

[0314] Specifically, the voltage of each path is different when the first circuit module forms a path alone, and when the first circuit module forms a path with different second circuit modules. Therefore, the control board 832 can determine whether the nozzle 10 is currently installed and the specific type of the nozzle 10 based on the measured path voltage, and thus control the hair care appliance to switch to the corresponding working mode.

[0315] Referring to Figures 1, 3 and 25, further, in some embodiments, in each nozzle 10, the second circuit module has a corresponding resistor so that the voltage of the path detected by the control board 832 is different.

[0316] Since the resistance value of the second circuit module in each nozzle 10 is different, the voltage of the path formed with the first circuit module will also be different. Therefore, the type of nozzle 10 can be determined by detecting the voltage.

[0317] Specifically, a resistor element with a corresponding resistance value can be connected in series in the second circuit module of each nozzle 10 so that the second circuit module has different resistances.

[0318] Referring to Figures 1, 3, and 25, in some embodiments, after the control board 832 determines that the nozzle 10 is in the installed state, it can control the first circuit module to supply power to the electrical components in the nozzle 10. Thus, it is unnecessary to separately install a battery or other power supply component in the nozzle 10.

[0319] Specifically, the electrical components in the nozzle 10 may be an NTC temperature detector, a negative ion generator, a water ion generator, an essential oil atomizer, etc.

[0320] Referring to Figures 1, 3, and 25, in some embodiments, a first NTC temperature detector is connected to the first circuit module, and a second NTC temperature detector is connected to the second circuit module. When the control board 832 determines that the nozzle 10 is in an uninstalled state, it reads the detection value of the first NTC temperature detector; when the control board 832 determines that the nozzle 10 is in an installed state, it reads the detection value of the second NTC temperature detector.

[0321] Specifically, the NTC temperature sensor is used to detect the airflow temperature to prevent overheating that could damage the hair or underheating that could result in low drying efficiency. Each operating mode has an optimal airflow temperature range. In the corresponding operating mode, the control board 832 can perform negative feedback adjustment on the power of the heating wire 834 based on the temperature measured by the NTC temperature sensor, so that the airflow temperature is more stably within the optimal range, improving the accuracy of airflow temperature control.

[0322] When the nozzle 10 is not installed, the unit 20 is used alone. The airflow exits the unit 20 and blows directly onto the hair. Therefore, the airflow temperature detected by the first NTC temperature detector in the first circuit module is very close to the actual airflow temperature blowing onto the hair. At this time, the detection value of the first NTC temperature detector can be directly read. When the nozzle 10 is installed, the unit 20 and the nozzle 10 are used together. The nozzle 10 introduces ambient airflow to increase the air volume. At this time, there is a large difference between the fluid temperature detected by the first NTC temperature detector and the actual airflow temperature blowing onto the hair. Therefore, the detection value of the second NTC temperature detector, which is closer to the end of the airflow path, is read to improve the accuracy of the reading.

[0323] Referring to Figures 1, 3, and 25, in some embodiments, the nozzle 10 includes a first electrical connector 600 electrically connected to the second circuit module, and the body 20 includes a second electrical connector 700. The first circuit module is electrically connected between the second electrical connector 700 and the control board 832. When the hair care appliance is in the installed state where the nozzle 10 is installed on the body 20, the first electrical connector 600 and the second electrical connector 700 are in contact and conductive, so that the first circuit module and the second circuit module together form a circuit.

[0324] Referring to Figure 4, the second electrical connector 700 is located at the air outlet 812 and is positioned lower than the air outlet 812. This protects the second electrical connector 700 from accidental contact and damage.

[0325] The specific structure and installation position of the first electrical connector 600 and the second electrical connector 700 can be referred to in the aforementioned embodiments. In addition, it should be noted that, as mentioned in the aforementioned embodiments, the wire connection segment 720 and the control board 832 are electrically connected, specifically through the first circuit module and the control board 832.

[0326] Referring to Figures 37 and 42 to 44, an embodiment of this application provides a hair combing brush 30-100, which includes a main structure 30-120, a movable panel 30-150, and a triggering mechanism 30-200. The main structure 30-120 has a second air duct 30-1321 for connection to a wind unit, and a second air outlet 30-142 communicating with the second air duct 30-1321, as well as comb teeth 30-141 arranged in an array and extending along the extension direction of the comb teeth 30-141. The movable panel 30-150 has through holes 30-153 for the comb teeth 30-141 to pass through. As shown in Figure 38, when the movable panel 30-150 is in the combing position (i.e., combing state), the movable panel 30-150 is located at the comb teeth 30-141. 141 is located near the extended head end of the main structure 30-120; as shown in FIG42, when the movable panel 30-150 is in the cleaning position (i.e., the cleaning state), the movable panel 30-150 is located at the extended end of the comb teeth 30-141 away from the main structure 30-120; the triggering mechanism 30-200 is embedded in the main structure 30-120, including an operating unit and a locking unit that is pulsatorically connected to the operating unit, the operating unit being slidably connected to the main structure 30-120, and the locking unit being connected to the movable panel 30-150; the operating unit is configured to be operablely movable to drive the movable panel 30-150 to move from the combing position to the cleaning position along the length direction of the comb teeth 30-141 (which is also the extension direction of the comb teeth 30-141) through the locking unit.

[0327] When using the aforementioned hair comb 30-100, the movable panel 30-150 is in the combing position, and the comb teeth 30-141 comb the hair, such as head hair. When it is necessary to clean the hair tangled on the comb teeth 30-141, the trigger mechanism 30-200 is used to move the movable panel 30-150 from the combing position to the cleaning position. This moves the movable panel 30-150 to the extension end of the comb teeth 30-141 away from the main structure 30-120, thereby pushing out the tangled hair. This makes it easier for the user to remove the hair tangled on the comb teeth 30-141, ensuring the combing effect during subsequent use and improving the user experience. Meanwhile, since the main structure 30-120 is equipped with a second air duct 30-1321 for connecting with the wind unit and a second air outlet 30-142 connected to the second air duct 30-1321, air can be discharged from the second air outlet 30-142 to dry the hair, etc.

[0328] As shown in Figure 42, in some embodiments, when the movable panel 30-150 moves to the cleaning position and enters the cleaning state, the top surface (i.e., the extended end) of the comb teeth 30-141 protrudes beyond the outer surface of the movable panel 30-150. This arrangement prevents the comb teeth 30-141 from shifting and causing them to easily contact the panel when resuming the combing state. The top surface of the comb teeth 30-141 protruding beyond the outer surface of the movable panel 30-150 by 30-0.30-5mm is sufficient; too long a protrusion would hinder cleaning.

[0329] As shown in Figure 43, in some embodiments, the diameter of the perforations 30-153 on the movable panel 30-150 is larger than the outer diameter of the comb teeth 30-141, ensuring that the comb teeth 30-141 can move along the lifting direction of the perforations 30-153. To prevent dust from entering the lower inner side of the movable panel 30-150 through the perforations 30-153, the diameter of the perforations 30-153 is less than 30-6mm. The perforations 30-153 provide a moving channel for the comb teeth 30-141, and the shape of the perforations 30-153 is not limited to a circle, but can also be elongated, etc.

[0330] As shown in Figures 43 and 44, in one embodiment, the movable panel 30-150 includes a panel body 30-151 and a panel cover 30-152 connected to the panel body 30-151. During user use, the panel cover 30-152 remains in contact with the hair. To prevent static electricity from easily generated between the plastic parts and the hair, which could cause frizz and damage to the hairstyle, the outer surface of the panel cover 30-152 has an anti-static function. Specifically, it can be made of metal or an anti-static material, or its surface can be coated with an anti-static coating. In some embodiments, the panel cover 30-152 can also be integrally formed with the panel body 30-151.

[0331] Referring to Figures 43 and 44, in one embodiment, the main structure 30-120 includes a housing 30-130 and a base plate 30-140 connected between the housing 30-130 and the movable panel 30-150. The comb teeth 30-141 and the second air outlet 30-142 are spaced apart on the base plate 30-140. A first mounting groove 30-131 is provided on the side of the housing 30-130 away from the base plate 30-140 (i.e., the left side of the housing 30-130 in Figure 44). The hair combing brush 30-100 also includes a cover 30-110, which covers the first mounting groove 30-131 to form a mounting cavity. The triggering mechanism 30-200 is slidably connected to the cavity wall of the mounting cavity along the lifting direction. By setting the cover 30-110, the trigger mechanism 30-200 inside the mounting cavity is sealed, improving dustproof performance and thus extending the service life of the component, while also enhancing the overall aesthetics of the hair combing brush 30-100. Specifically, the cover 30-110 is provided with a hook 30-111, and the housing 30-130 is provided with a slot 30-135 for engaging with the hook 30-111. The connection between the cover 30-110 and the housing 30-130 is achieved through the cooperation of the hook 30-111 and the slot 30-135. Of course, the positions of the hook 30-111 and the slot 30-135 can also be interchanged.

[0332] Referring to Figures 43 to 46, in one embodiment, the operating unit includes a pull ring 30-210, on which a transmission part 30-211 is provided; the locking unit includes a first locking plate 30-220, which is connected to the movable panel 30-150 and slidably connected to the transmission part 30-211, so as to convert the movement of the pull ring 30-210 along the lifting direction into the movement of the first locking plate 30-220 along the extension direction of the comb teeth 30-141, thereby driving the movable panel 30-150 to move from the combing position to the cleaning position; the lifting direction intersects with the extension direction of the comb teeth 30-141. For example, in the perspective shown in Figure 43, the lifting direction is the up-down direction, which is also the length direction of the pull ring 30-210; the extension direction of the comb teeth 30-141 is the left-right direction. Through the sliding engagement of the first locking plate 30-220 and the transmission part 30-211, the displacement of the pull ring 30-210 along the lifting direction is converted into the displacement of the movable panel 30-150 along the extension direction of the comb teeth 30-141, thereby realizing the switching of the movable panel 30-150 in different states.

[0333] To facilitate pulling the pull ring 30-210 in the lifting direction, a finger hole is provided on the pull ring 30-210 for users to insert their fingers. This allows the user to insert their fingers into the finger hole to pull the ring, triggering the movable panel 30-150 to enter the cleaning position, corresponding to the hair combing brush 30-100 being in the cleaning state. When cleaning is complete and the movable panel 30-150 needs to be returned to its original position, the user can press the bottom of the finger hole to reset the movable panel 30-150, or press the top of the pull ring 30-210 with their palm or a table surface to reset it.

[0334] Referring to Figures 43 to 46, in one embodiment, the upper end of the pull ring 30-210 is a trigger end for the user to operate the pull ring 30-210, and the lower end of the pull ring 30-210 is a transmission end that cooperates with the trigger mechanism 30-200. The transmission part 30-211 includes a transmission guide rail 30-2111, which can specifically be a groove provided on the transmission end of the pull ring 30-210. The extension direction of the transmission guide rail 30-2111 intersects the lifting direction and the extension direction of the comb teeth 30-141. That is, the transmission guide rail 30-2111 is inclined, so that the displacement in the lifting direction can be converted into displacement along the extension direction of the comb teeth 30-141. Specifically, at least one side of the first locking plate 30-220 extends outward with a first locking protrusion 30-221, which slides in engagement with the groove of the transmission guide rail 30-2111. As shown in Figures 46 and 45, when the movable panel 30-150 is in the combing position shown in Figure 46, the first locking protrusion 30-221 is located at the left limit position of the transmission guide rail 30-2111; when the movable panel 30-150 is in the cleaning position shown in Figure 45, the first locking protrusion 30-221 is located at the right limit position of the transmission guide rail 30-2111. When the movable panel 30-150 moves from the combing position to the cleaning position, the first locking protrusion 30-221 slides along the transmission guide rail 30-2111.

[0335] To improve the sliding engagement and smoothness of the first locking plate 30-220 and the pull ring 30-210, in another embodiment, the first locking plate 30-220 is provided with first locking protrusions 30-221 on both sides along its width direction. Correspondingly, the pull ring 30-210 is also provided with transmission guide rails 30-2111 on both sides along its width direction. The number of first locking protrusions 30-221 and transmission guide rails 30-2111 along the pulling direction of the pull ring 30-210 can be set according to actual needs; for example, one or two can be provided.

[0336] As shown in Figures 45 and 46, in a specific embodiment, the transmission guide rail 30-2111 is inclined, and the angle between the transmission guide rail 30-2111 and the lifting direction of the pull ring 30-210 can be 30-45 degrees. The transmission guide rail 30-2111 is similar to the longest side of an isosceles right triangle. The distance that the pull ring 30-210 moves upward is the same as the distance that the first locking plate 30-220 moves to the right, and the two move synchronously. For example, when the pull rod moves upward by 30-14 mm, the first locking plate 30-220 and the movable panel 30-150 also move horizontally to the right by 30-14 mm.

[0337] Referring to Figures 43 to 46, in one embodiment, the transmission part 30-211 includes a straight groove 30-2112 connected to both ends of the extension direction of the transmission guide rail 30-2111. The extension direction of the straight groove 30-2112 is parallel to the lifting direction. When the first locking protrusion 30-221 is located in the straight groove 30-2112, the groove wall of the straight groove 30-2112 restricts the first locking plate 30-220 from moving along the extension direction of the comb teeth 30-141. When the movable panel 30-150 is away from the housing 30-130, the straight groove 30-2112 prevents the movable panel 30-150 from moving due to accidental pressing during cleaning. It is understood that the hair combing brush 30-100 may also include a handle, which is snapped and fixed to the main body 30-120. When pulling the ring 30-210, the user can hold the handle with one hand and pull the ring 30-210 with the other. Since the displacement of the main body 30-120 along the lifting direction is limited by the handle, the displacement reliability of the movable panel 30-150 along the extension direction of the comb teeth 30-141 is guaranteed.

[0338] Referring to Figures 43-44 and 57, in one embodiment, the cover 30-110 is provided with a first limiting rib 30-112. The first limiting rib 30-112 is used to abut against the pull ring 30-210 of the trigger mechanism 30-200 to prevent the trigger mechanism 30-200 from moving along the extension direction of the comb teeth. Through the abutment between the two, the movement of the pull ring 30-210 of the trigger mechanism 30-200 along the extension direction of the comb teeth 30-141 is restricted. Furthermore, the pull ring 30-210 of the triggering mechanism 30-200 is provided with a first guide groove 30-2113 for sliding engagement with the first limiting rib 30-112. The first guide groove 30-2113 extends along the lifting direction, and the first limiting rib 30-112 abuts against the groove wall of the first guide groove 30-2113, so that the first limiting rib 30-112 can only move along the extension direction of the first guide groove 30-2113. Thus, the movement of the triggering mechanism 30-200 is guided by the first guide groove 30-2113, improving the reliability of the movement of the triggering mechanism 30-200 along the lifting direction. Of course, the positions of the first limiting rib 30-112 and the first guide groove 30-2113 can also be interchanged.

[0339] Furthermore, referring to Figures 43 and 44, at least one side of the pull ring 30-210 of the trigger mechanism 30-200 along the width direction is provided with a second limiting rib 30-230. The second limiting rib 30-230 is used to abut against the housing 30-130, thereby restricting the movement of the pull ring 30-210 along the width direction of the hair combing brush 30-100, so that the pull ring 30-210 can only slide in the lifting direction, thereby ensuring the reliability of the displacement of the movable panel 30-150 along the extension direction of the comb teeth 30-141. It can be understood that the second limiting rib can also be provided on the housing, and the second limiting rib abuts against the outer side of the pull ring.

[0340] Referring to Figures 44 to 46, in one embodiment, a guide connecting post 30-154 is provided on the side of the movable panel 30-150 facing the housing 30-130. The guide connecting post 30-154 passes through the base plate 30-140 and the housing 30-130. Specifically, the guide connecting post 30-154 extends along the movement direction of the movable panel 30-150 (i.e., the extension direction of the comb teeth 30-141) and along the side of the movable panel 30-150 facing the housing 30-130, and passes through the base plate 30-140 and the housing 30-130 to connect with the first locking plate 30-220. The first locking plate 30-220 may be provided with a third mounting groove 30-222 for interference fit with the guide connecting post 30-154. In this way, the pull ring 30-210 can drive the guide connecting post 30-154 and the movable panel 30-150 to move synchronously along the extension direction of the comb teeth 30-141. At the same time, the guide connecting post 30-154 provides motion guidance for the movable panel 30-150, so that hair and other debris wrapped around the comb teeth 30-141 can move with the movable panel 30-150, making it easier for the user to clean.

[0341] Referring to Figures 47 and 48, in one embodiment, the pull ring 30-210 includes a pull rod frame 30-212 and a handle portion 30-213 connected to the pull rod frame 30-212. A transmission guide rail 30-2111 is disposed on the pull rod frame 30-212, and a finger hole is disposed on the handle portion 30-213. The pull rod frame 30-212 and the handle portion 30-213 can be integrally formed or detachably connected. Further, the pull rod frame 30-212 is provided with a sliding groove 30-2121, through which the handle portion 30-213 is rotatably connected to the pull rod frame 30-212. Thus, when the user pulls the handle portion 30-213, the direction can be adjusted, allowing the user to move the movable panel 30-150 from multiple angles.

[0342] As shown in Figures 39 and 42 to 44, in some embodiments, the housing 30-130 is constructed with a clearance groove 30-136. When the movable panel 30-150 is in the combing position, the handle portion 30-213 of the pull ring 30-210 is located within the clearance groove 30-136. That is, the handle portion 30-213 does not protrude from the outer surface of the housing 30-130; that is, the outer surface of the handle portion 30-213 is flush with or slightly lower than the outer surface of the main structure 30-120. Thus, when using the hair combing brush 30-100 for combing, because the handle portion 30-213 does not protrude, it can prevent the user from accidentally touching the handle portion 30-213 during use, causing the movable panel 30-150 to move to the cleaning position, and also reduces the risk of the handle portion 30-213 protruding and hindering user use. When the movable panel 30-150 is moved to the cleaning position, the handle 30-213 of the pull ring 30-210 will protrude from the surface of the housing 30-130. The housing 30-130 and the cover 30-110 together constitute the outer surface of the hair combing brush 30-100. The pull ring 30-210 is U-shaped. When the movable panel 30-150 is in the combing position, part of the handle 30-213 of the pull ring 30-210 constitutes part of the outer surface of the hair combing brush 30-100.

[0343] As shown in Figures 43 and 44, when assembling the hair combing brush 30-100, the base plate 30-140 with comb teeth 30-141 is connected to the housing 30-130 by screws. The base plate 30-140 is connected to the housing 30-130 by screws around its perimeter and in the center. When the hair combing brush 30-100 also includes a connector head 30-160 for connecting a handle, the connector head 30-160 is aligned with the housing 30-130 and connected by screws. Furthermore, the guide connecting post 30-154 passes through the housing 30-130. The first locking plate 30-220 is connected to the second locking plate 30-220 by screws. The pull ring 30-210 is a plastic part with a certain degree of deformation. The pull ring 30-210 is fastened to the back of the first locking plate 30-220 along the pulling direction of the pull ring 30-210, so that the first locking protrusion 30-221 slides and engages with the transmission guide rail 30-2111. Then, the hook 30-111 on the cover 30-110 engages with the slot 30-135 on the housing 30-130 to realize the connection between the cover 30-110 and the housing 30-130.

[0344] Unlike the triggering mechanism 30-200 described above, as shown in Figures 50 to 54, in another embodiment, the operating unit in the triggering mechanism 30-200 includes a second operating button 30-310, and the locking unit in the triggering mechanism 30-200 includes a second locking plate 30-330 connected to the second operating button 30-310. The second locking plate 30-330 is connected to the movable panel 30-150. When the second operating button 30-310 is pressed along the extending direction of the comb teeth 30-141, the second locking button transmits the pressing force to the second locking plate 30-330, thereby enabling the movable panel 30-150 to move from the combing position shown in Figure 49 to the cleaning position shown in Figure 52 through the second locking plate 30-330. The second operation button 30-310 is located on the side of the cover 30-110 opposite to the comb teeth 30-141. When the movable panel 30-150 is in the combing position, the second operation button 30-310 protrudes from the surface of the cover 30-110 for easy pressing by the user. When the movable panel 30-150 is in the cleaning position, at least a portion of the second operation button 30-310 is located within the mounting cavity of the cover 30-110 and the housing 30-130.

[0345] As shown in Figures 50 to 54, in one embodiment, the triggering mechanism 30-200 further includes a rotating latch 30-320 abutting against the second operation button 30-310. The rotating latch 30-320 has a fulcrum end 30-321 and a resistance end 30-322. The fulcrum end 30-321 is rotatably connected to the housing 30-130, and the resistance end 30-322 abuts against the second latch plate 30-330. As shown in Figure 54, when the second operation button 30-310 is pressed, the rotating latch 30-320 transmits the force to the second latch plate 30-330 connected to it, thereby driving the second latch plate 30-330 and the movable panel 30-150 to move synchronously. Specifically, the fulcrum end 30-321 is provided with a first rotating shaft 30-324, and the second operation button 30-310 is rotatably connected to the housing 30-130 through the first rotating shaft 30-324; the first rotating shaft 30-324 is embedded in the rotating shaft groove in the mounting groove of the housing 30-130 and can rotate within the rotating shaft groove. By rotating the latch 30-320 to the housing 30-130, the latch 30-320 is limited to a certain extent, preventing the latch 30-320 from shifting and affecting its connection with the second latch plate 30-330, thereby improving the force transmission stability between the latch 30-320 and the second latch plate 30-330. Further, the second latch plate 30-330 is provided with an abutment groove 30-333, and the resistance end 30-322 abuts against the abutment groove 30-333. The interlocking of the abutment groove 30-333 and the rotating latch 30-320 enhances the connection reliability and force transmission stability of the second latch plate 30-330 and the rotating latch 30-320.

[0346] As shown in Figures 54 and 55, in one embodiment, the second operation button 30-310 is provided with a first boss 30-311 on at least one side along the width direction, and the rotating latch 30-320 further includes a power end 30-323 located between the fulcrum end 30-321 and the resistance end 30-322, the power end 30-323 abutting against the first boss 30-311. In other words, the rotating latch 30-320 is similar to a lever structure. The housing 30-130 limits the fulcrum end 30-321 of the rotating latch 30-320. The second operating button 30-310 transmits the pressing pressure to the power end 30-323. Then, the resistance end 30-322, which is farther from the fulcrum end 30-321, reduces the pressing pressure and transmits it to the second latch plate 30-330. This prevents excessive pressing pressure from causing the movable panel 30-150 to move excessively or from accidental contact causing it to shift to a cleaning position. The power end 30-323 of the rotating latch 30-320 can be a protrusion extending towards the second operating button 30-310, facilitating force transmission with the first protrusion 30-311. Furthermore, the second operation button 30-310 is provided with a first boss 30-311 on both sides along its width direction. Correspondingly, the rotating latch 30-320 is provided with a power end 30-323 and a resistance end 30-322 at both ends along its width direction to ensure the stability of the second latch plate 30-330 moving along the extension direction of the comb teeth 30-141.

[0347] As shown in Figures 50 to 54, in one embodiment, the movable panel 30-150 is provided with a guide connecting post 30-154 on the side facing the housing 30-130. The guide connecting post 30-154 passes through the base plate 30-140 and the housing 30-130 in sequence and is press-fitted with the second locking plate 30-330. The guide connecting post 30-154 provides motion guidance for the movable panel 30-150, allowing hair and other debris entangled on the comb teeth 30-141 to move with the movable panel 30-150, thus facilitating user cleaning. As shown in Figures 54 and 56, the second locking plate 30-330 is provided with a second mounting groove 30-332 for press-fitting with the guide connecting post 30-154.

[0348] As shown in Figures 50 to 54, in one embodiment, a first reset member 30-331 is connected between the second locking plate 30-330 and the housing 30-130. After the external force acting on the second operation button 30-310 is removed, the first reset member 30-331 drives the second locking plate 30-330 to move the movable panel 30-150 back to the combing position. By providing the second reset member 30-463, the movable panel 30-150 can automatically reset from the cleaning position to the combing position after the pressing pressure is removed, facilitating subsequent combing operations.

[0349] For example, in the perspectives shown in Figures 54 and 55, when the second operation button 30-310 is pressed down, the first protrusion 30-311 on the second operation button 30-310 simultaneously pushes the power end 30-323 of the rotating latch 30-320 downward. This, in turn, causes the resistance end 30-322 to move downward under the action of the fulcrum end 30-321, thereby pushing the second latch plate 30-330 connected to the resistance end 30-322 downward. Since the second latch plate 30-330 is connected to the movable panel via the guide connecting post 30-154... The connection between 30-150 causes the movable panel 30-150 to move downwards, i.e., the movable panel 30-150 is pushed out relative to the base plate 30-140 to the cleaning position. During this process, the first reset member 30-331 is compressed, or the compression of the first reset member 30-331 increases. After the pressure applied to the second operation button 30-310 is removed, the movable panel 30-150 returns to the combing position under the action of the first reset member 30-331, i.e., the movable panel 30-150 and the second locking plate 30-330 move upwards.

[0350] As shown in Figures 36 to 41, in a further embodiment of this application, a hair care device is provided, including a body 30-400 and a hair combing brush 30-100 detachably connected to the body 30-400 as described above. The body 30-400 can have the structure of the body 20 as described above. In this embodiment, a control board is provided inside the body 30-400, and a power source is connected to the outside of the body 30-400. The power source can be a power cord 30-500 and plug connected to mains power, or a battery pack. The power source is electrically connected to the control board, which can control the operation of components inside the body 30-400, such as the fan unit 30-420 and the heating unit 30-430. The body 30-400 is generally cylindrical, and the power source, the air inlet of the body 30-400, the control board, the fan unit 30-420, the heating unit 30-430, and the air outlet of the body 30-400 are arranged sequentially from bottom to top.

[0351] As shown in Figure 41, in one embodiment, the side of the body 30-400 is provided with a first air inlet 30-411 (i.e., the air inlet of the body 30-400), the top surface of the body 30-400 is provided with a first air outlet (i.e., the air outlet of the body 30-400), and the body 30-400 is provided with a first air duct 30-410 connecting the first air inlet 30-411 and the first air outlet, and a wind unit 30-420 located in the first air duct 30-410. As shown in Figures 41 to 44, a second air outlet 30-142 is provided on the bottom plate 30-140 located between the housing 30-130 and the movable panel 30-150, which is spaced apart from the comb teeth 30-141; the housing 30-130 is constructed with a cavity 30-132 that opens towards the second air outlet 30-142 and communicates with the second air outlet 30-142, and the cavity 30-132 forms a second air duct 30-1321 that communicates with the first air outlet, and the shape of the cavity 30-132 is approximately the same as the outer shape of the housing 30-130.

[0352] Specifically, the wind unit 30-420 includes a motor and an impeller. After the motor operates, the impeller rotates to generate negative pressure, causing gas to enter the first air duct 30-410 through the first air inlet 30-411 at the bottom of the body 30-400, flow through the control board into the motor air inlet, and then enter the second air duct 30-1321 and exit through the second air outlet 30-142 to dry wet hair. Further, a heating unit 30-430 is installed inside the first air duct 30-410, located between the wind unit 30-420 and the first air outlet. The heating unit 30-430 heats the gas in the first air duct 30-410, causing hot air to be blown out from the second air outlet 30-142, which improves the drying efficiency of hair and also facilitates styling. The first air inlet 30-411 is equipped with a filter screen 30-412 to prevent dust from contaminating the electrical components inside the body 30-400.

[0353] As shown in Figures 43 and 58, in one embodiment, the housing 30-130 has a first protrusion 30-133 on the side facing the base plate 30-140, and the first protrusion 30-133 is located within the cavity 30-132. The first protrusion 30-133 can be elongated and located in the central region of the cavity 30-132, making the second air duct 30-1321 annular, i.e., racetrack-shaped. The racetrack-shaped cavity 30-132 surrounds the first protrusion 30-133, resulting in a more uniform airflow distribution, allowing users to dry their hair faster and more evenly. There is a gap between the first protrusion 30-133 and the base plate 30-140, meaning the top of the first protrusion 30-133 is spaced apart from the base plate 30-140, ensuring that some air is still discharged from the air outlet of the base plate 30-140 corresponding to the first protrusion 30-133.

[0354] Furthermore, as shown in Figures 44, 57 and 59, a receiving groove 30-1331 is provided on the back side of the first protrusion 30-133 (i.e. the side facing the cover 30-110), that is, the first protrusion 30-133 is a hollow structure, so that part of the trigger mechanism 30-200 located on the back side of the first protrusion 30-133 can be accommodated in the receiving groove 30-1331, thereby saving the space occupied by the trigger mechanism 30-200 along the extension direction of the comb teeth 30-141.

[0355] As shown in Figures 57 to 62, in some embodiments, one of the housing 30-130 and the base plate 30-140 is provided with an annular sealing groove 30-137, and the other is provided with an annular sealing ring 30-143 for engaging with the annular sealing groove 30-137. For example, in this embodiment, an annular sealing groove 30-137 is provided on the housing 30-130, and an annular sealing ring 30-143 is provided on the base plate 30-140. Through the snap-fit ​​cooperation of the sealing groove 30-137 and the sealing ring 30-143, the accommodating groove 30-1331 and the second air duct 30-1321 (racetrack-shaped cavity 30-132) are isolated. This ensures that during the operation of the hair combing brush 30-100, the gas in the second air duct 30-1321 will not flow into the accommodating groove 30-1331 used to install the trigger mechanism 30-200. This ensures that the trigger mechanism 30-200, which is clamped in the racetrack-shaped cavity 30-132 and moves within the accommodating groove 30-1331, will not affect the airflow, thus ensuring the reliability of the air outlet. It is understood that the positions of the sealing ring and the sealing groove can be interchanged.

[0356] As shown in Figure 43, in one embodiment, the first protrusion 30-133 is provided with a first fastening part 30-134 for connecting and engaging with the base plate 30-140. The first fastening part 30-134, such as a screw sleeve, is located at the center of the first protrusion 30-133 and engages with the stud hole of the base plate 30-140 to strengthen the fixation of the base plate 30-140. Further, the first fastening part 30-134 extends from the end face of the first protrusion 30-133 toward the base plate 30-140. That is, the first fastening part 30-134 protrudes from the first protrusion 30-133, maintaining a gap of 30-0.30-5mm-30-2mm between the inner surface of the base plate 30-140 and the top surface of the first protrusion 30-133. With this configuration, air can be vented from the entire base plate 30-140. The air volume is large in the racetrack-shaped cavity 30-132, while the air volume is small at the position corresponding to the first protrusion 30-133. This makes the airflow feel gentle when the user is styling, thus improving the user experience.

[0357] As shown in Figures 42 and 43, in one embodiment, the movable panel 30-150 is provided with a third air outlet 30-155 that communicates with the second air outlet 30-142. The third air outlet 30-155 is adapted to the shape and size of the second air outlet 30-142 on the base plate 30-140. Multiple second air outlets 30-142 and multiple third air outlets 30-155 are arranged at intervals, with a higher density of second air outlets 30-142 and third air outlets 30-155 located on the outer ring of the runway-shaped cavity 30-132, and a lower density of second air outlets 30-142 and third air outlets 30-155 located at the position of the first protrusion 30-133.

[0358] As shown in Figures 43 and 44, in one embodiment, the hair combing brush 30-100 further includes a connector 30-160 connected to the body 30-400 and aligned with the first air outlet. The connector 30-160 has a first through hole 30-161 for connecting the first air outlet and the second air duct 30-1321. That is, the connector 30-160 is approximately a hollow sleeve. The outer wall of the connector 30-160 is used for connection and installation with the housing 30-130, and the inner wall of the connector 30-160 forms a second air inlet aligned with the air outlet of the body 30-400. The second air inlet can be circular or other shapes, such as square or polygonal. The connector 30-160 is connected to the housing 30-130 by screws.

[0359] As shown in Figure 38, in one embodiment, the body 30-400 is provided with control buttons 30-440. Specifically, the control buttons 30-440 include a switch button 30-441, a speed adjustment button 30-442, and a cool air switch button 30-443, which are spaced apart. By pressing the corresponding button, the hair brush 30-100 blows out air at different temperatures and air volumes. A grip portion 30-450 is provided between the control buttons 30-440 and the first air inlet 30-411 for the user to hold, making it convenient for the user to hold the hair care tool.

[0360] As shown in Figures 39 and 40, in one embodiment, the body 30-400 is provided with a first engaging portion 30-461, and the hair combing brush 30-100 is provided with a second engaging portion 30-162 for engaging with the first engaging portion 30-461. Specifically, the first engaging portion 30-461 can be a engaging protrusion, and the second engaging portion 30-162 can be a engaging groove. The engagement of the engaging protrusion and the engaging groove enables the connection between the body 30-400 and the hair combing brush 30-100. The second engaging portion 30-162 is located on the connector 30-160. Alternatively, the body 30-400 can have an engaging groove, and the hair combing brush 30-100 can have an engaging protrusion. Meanwhile, the engagement of the first engaging part 30-461 and the second engaging part 30-162 restricts the possibility of the hair combing brush 30-100 moving relative to the body 30-400 along the axis of the body 30-400, ensuring that the hair combing brush 30-100 will not separate from the body 30-400 when the user pulls the trigger mechanism 30-200.

[0361] As shown in Figures 39 and 40, in one embodiment, a transmission member 30-460 is provided on the body 30-400, and the first locking part 30-461 is located on the transmission member 30-460; a release push button 30-462 is connected to the transmission member 30-460. By pushing the release push button 30-462 downward, the transmission member 30-460 can be moved to the unlocked position in a direction away from the hair combing brush 30-100, so that the first locking part 30-461 disengages from the second locking part 30-162, that is, the hair combing brush 30-100 is unlocked from the body 30-400, and the user can replace the hair combing brush 30-100 or store the whole machine.

[0362] As shown in Figures 39 and 40, in one embodiment, a second reset member 30-463 is connected between the body 30-400 and the transmission member 30-460. When the external force acting on the release push button 30-462 is removed, the second reset member 30-463 drives the transmission member 30-460 to move towards the hair combing brush 30-100 to the locked position. By setting the second reset member 30-463, the transmission member 30-460 is kept in the pushed-out state, so that the first locking part 30-461 and the second locking part 30-162 engage, ensuring the reliability of the fixation of the body 30-400 to the hair combing brush 30-100.

[0363] As shown in Figures 36 and 37, in one embodiment, the release push button 30-462 and the control button 30-440 are located on opposite sides of the body 30-400. The release push button 30-462 is positioned opposite the control button 30-440 to prevent accidental triggering by the user. Furthermore, along the flow direction of the first air duct 30-410, the distance between the release push button 30-462 and the first air outlet is less than the distance between the control button 30-440 and the first air outlet. That is, the release button is positioned closer to the top of the body 30-400 than the control button 30-440. This arrangement brings the first latching portion 30-461 and the second latching portion 30-162 closer together, allowing the transmission component 30-460 to be shorter and the hair care appliance to be more compact.

[0364] As shown in Figures 63-64, an embodiment of this application discloses a hair curler nozzle, specifically a hair curler nozzle, comprising an inner cylinder 40-1, a hair curler shell 40-2, an upper cover 40-5, and a sealing cap 40-6. The inner cylinder 40-1 is embedded inside the hair curler shell 40-2. The inner cylinder 40-1 has an air inlet channel 40-10, a first air inlet 40-11 communicating with the air inlet channel 40-10, and a first air outlet 40-12 communicating with the air inlet channel 40-10. The upper cover 40-5 is disposed on the top of the inner cylinder 40-1, and the sealing cap 40-6 is snapped onto the upper cover 40-5.

[0365] As shown in Figures 65-66, the inner tube 40-1 has a cylindrical structure with only one end open. The inner tube 40-1 includes a support tube 40-14, an end head 40-15 extending downward from the support tube 40-14, and a support head 40-16 extending upward from the support tube 40-14. The support tube 40-14 is embedded in the curling shell 40-2, and the end head 40-15 and the support head 40-16 are exposed on the outside of the curling shell 40-2. The upper cover 40-5 covers the outside of the support head 40-16 of the inner tube 40-1 and is tightly attached to the curling shell 40-2. In this embodiment, the opening of the support cylinder 40-14 is the first air inlet 40-11, the inner cavity of the support cylinder 40-14 is the air inlet channel 40-10, and the peripheral surface of the support cylinder 40-14 is provided with a plurality of first air outlets 40-12 arranged along the length direction of the support cylinder 40-14. The first air outlets 40-12 penetrate the outer surface and the inner surface of the support cylinder 40-14, so that the first air outlets 40-12 are connected to the air inlet channel 40-10.

[0366] As shown in Figure 67, the curling shell 40-2 is a tubular, one-piece molded structure. The curling shell 40-2 includes connecting ribs 40-22 and several arc-shaped plates 40-21 arranged circumferentially around the axis of the curling shell 40-2. Each arc-shaped plate 40-21 extends axially. The guide gap formed at the connection points of adjacent arc-shaped plates 40-21 constitutes a second air outlet 40-23. Adjacent arc-shaped plates 40-21 are connected by connecting ribs 40-22. In this embodiment, the curling shell 40-2 is made of metal and is one-piece molded. Existing curling shells 40-2 are generally injection molded from plastic. Aluminum or aluminum alloy is the preferred material for the metal. Using aluminum or aluminum alloy makes the curling shell 40-2 lightweight, easy to process, and provides good heat transfer. The curling shell 40-2 is first formed by aluminum extrusion, and then stamped to form the second air outlet 40-23. The thickness of the arc plate 40-21 can be relatively thin, thereby reducing the weight of the nozzle.

[0367] As shown in Figure 68, specifically, the outer surface of the arc-shaped plate 40-21 is a first curved arc surface 40-210, and the tail end of the first curved arc surface 40-210 has a first inclined surface 40-211; the inner surface of the arc-shaped plate 40-21 is a second curved arc surface 40-220, and the head end of the second curved arc surface 40-220 has a second inclined surface 40-221. The second inclined surface 40-221 is located outside the first inclined surface 40-211, and the second inclined surface 40-221 and... A second air outlet 40-23 is formed between the first inclined surface 40-211, and the projection of the second inclined surface 40-221 on the plane where the first inclined surface 40-211 is located overlaps with the first inclined surface 40-211 at least partially, so that the airflow direction from the second air outlet 40-23 can be aligned with the outer wall of the curling shell 40-2 and blown out. The air outlet formed by this design satisfies the airflow direction control of the air outlet and does not rely on the inner cylinder structure, reducing the difficulty of the curling shell manufacturing and assembly process.

[0368] As shown in Figure 69, in this embodiment, the first inclined surface 40-211 and the second inclined surface 40-221 are parallel to each other, and the distance d between the first inclined surface 40-211 and the second inclined surface 40-221 is 0.3-0.5mm. Referring to Figure 68, the connecting rib 40-22 is connected to both the first inclined surface 40-211 and the second inclined surface 40-221, which helps to keep the first inclined surface 40-211 and the second inclined surface 40-221 parallel.

[0369] As shown in Figures 69 and 70, the first curved surface 40-210 includes a main curved surface 40-212 and a transition curved surface 40-213. One side of the transition curved surface 40-213 is smoothly connected to the first inclined surface 40-211, and the other side is smoothly connected to the main curved surface 40-212. The transition curved surface 40-213 allows the airflow from the second air outlet 40-23 to better conform to the main curved surface 40-212. The angle α formed by the tangent Y of the main curved surface 40-212 at the junction of the main curved surface 40-212 and the transition curved surface 40-213 and the airflow direction X of the second air outlet 40-23 is 20-30 degrees. The angle α can be set as needed. The smaller the angle α, the better the curling effect. That is, the best curling effect can be achieved when the angle α is 20 degrees.

[0370] The curling shell 40-2 can have 6 to 9 arc-shaped plates 40-21. In this embodiment, 6 arc-shaped plates 40-21 are used as an example. The thickness of the arc-shaped plates 40-21 is 0.8-2.5mm. A thickness between 1.0-1.5mm is beneficial for the processing of the curling shell 40-2 and ensures that the material does not deform, i.e., it is stable. Two adjacent arc-shaped plates 40-21 are connected by connecting ribs 40-22 to form a slit, which is the second air outlet 40-23.

[0371] As shown in Figure 70, in this embodiment, the maximum outer diameter D of the arc-shaped plate 40-21 is 15-20 mm. The maximum outer diameter D of the arc-shaped plate 40-21 is the distance d between the first inclined surface 40-211 and the second inclined surface 40-221, which is 30-70 mm.

[0372] As shown in Figure 70, the arc-shaped plate 40-21 on the curling shell 40-2 is petal-shaped, and the maximum outer diameter of the curling shell 40-2 overlaps with the outer diameter arc of the arc plate 40-21.

[0373] The first air outlet 40-12 and the second air outlet 40-23 are staggered, so that the airflow from the first air outlet 40-12 first travels along the inner wall of the curling shell 40-2 to the second air outlet 40-23, and finally the airflow is led out from the second air outlet 40-23 and travels along the outer wall of the curling shell 40-2.

[0374] Multiple first air outlets 40-12 are provided, and the multiple first air outlets 40-12 are circumferentially distributed on the outer surface of the inner cylinder 40-1. The multiple first air outlets 40-12 are arranged along the length direction of the inner cylinder 40-1, and the openings of the multiple first air outlets 40-12 gradually increase, gradually decrease, or remain unchanged along the length direction of the inner cylinder 40-1.

[0375] At least one sealing element 40-3 is provided between the inner cylinder 40-1 and the curling shell 40-2. The inner ring of the sealing element 40-3 engages with the inner cylinder 40-1, and the outer ring of the sealing element 40-3 is adapted to the shape of the curling shell 40-2 to facilitate the installation and positioning of the curling shell 40-2. The outer ring of the sealing element 40-3 abuts against the inner circumferential surface of the curling shell 40-2. In this embodiment, at least one sealing element 40-3 includes a pair of sealing elements 40-3, which are located at both ends of the inner cylinder 40-1.

[0376] The outer sides of both ends of the inner cylinder 40-1 protrude outward to form protrusions 40-13, and opening slots 40-130 are provided on the protrusions 40-130. The sealing element 40-3 has a first locking block 40-30 and a second locking block 40-31 protruding from opposite sides, symmetrically distributed on both sides of the sealing element 40-3. When the curling shell 40-2 needs to be installed in reverse, the sealing element 40-3 is fitted onto the inner cylinder 40-1 in the opposite direction. The first locking block 40-30 of the sealing element 40-3 installed at the upper end of the inner cylinder 40-1 and the first locking block 40-30 of the sealing element 40-3 installed at the lower end of the inner cylinder 40-1 are both installed downwards. At this time, the first locking block 40-30 of the sealing element 40-3 installed at the upper end of the inner cylinder 40-1 and the opening slot 40-130 at the upper end of the inner cylinder 40-1 are aligned with the opening slot 40-130 of the inner cylinder 40-1. 0-130 snap-fit; the second snap-fit ​​block 40-31 of the seal 40-3 installed at the lower end of the inner cylinder 40-1 snaps into the opening groove 40-130 at the lower end of the inner cylinder 40-1; when the hair curler shell 40-2 needs to be installed in the forward direction, the seal 40-3 is sleeved on the inner cylinder 40-1 in the forward direction, and the first snap-fit ​​block 40-30 of the seal 40-3 installed at the upper end of the inner cylinder 40-1 and the first snap-fit ​​block 40-30 of the seal 40-3 installed at the lower end of the inner cylinder 40-1 are both installed upward. At this time, the second snap-fit ​​block 40-31 of the seal 40-3 installed at the upper end of the inner cylinder 40-1 snaps into the opening groove 40-130 at the upper end of the inner cylinder 40-1; the first snap-fit ​​block 40-30 of the seal 40-3 installed at the lower end of the inner cylinder 40-1 snaps into the opening groove 40-130 at the lower end of the inner cylinder 40-1.

[0377] The end head 40-15 of the inner cylinder 40-1 has a fixing groove 40-150 for receiving the first card block 40-30 or the second card block 40-31 at the position corresponding to the first card block 40-30 or the second card block 40-31.

[0378] The sealing element 40-3 is either ring-shaped or strip-shaped. In this embodiment, the sealing element 40-3 at the upper end of the inner cylinder 40-1 is ring-shaped, and the sealing element 40-3 at the lower end of the inner cylinder 40-1 is strip-shaped. It is formed by cutting the ring-shaped sealing element at the position corresponding to the first locking block 40-30. The reason is that the sealing element 40-3 at the lower end of the inner cylinder 40-1 would be difficult to assemble by sliding it from the upper end of the inner cylinder 40-1 to the lower end of the inner cylinder 40-1. Therefore, it is cut into strip shape. Then, the first locking block 40-30 is inserted into the opening groove 40-130 or the fixing groove 40-150, making it easier to assemble the sealing element 40-3 at the lower end of the inner cylinder 40-1.

[0379] In this embodiment, the lower end face of the upper cover 40-5 abuts against the side of the sealing member 40-3 to form a seal, and the inner circumferential surface of the upper cover 40-5 abuts against the outer side of the locking block 40-30.

[0380] As shown in Figure 71, a hair care device according to an embodiment of this application is specifically a curling iron, including the above-mentioned suction curling nozzle and main body 40-4. The suction curling nozzle is fixedly connected to the main body 40-4, and the main body 40-4 can be the body 20 as described above.

[0381] In use, the main body 40-4 serves as the air outlet. When the air is blown out, the airflow first enters the air intake channel 40-10 of the inner cylinder 40-1 through the first air inlet 40-11. Since the first air outlet 40-12 on the circumferential surface of the support cylinder 40-14 is connected to the air intake channel 40-10, the airflow will be discharged from the first air outlet 40-12. Due to the staggered distribution of the first air outlet 40-12 and the second air outlet 40-23, the airflow from the first air outlet 40-112 to the second air outlet 40-23 is routed along the inner wall of the curling shell 40-2 to the second air outlet 40-23. Finally, the airflow is discharged from the second air outlet 40-23 and routed along the outer wall of the curling shell 40-2.

[0382] Unlike existing technologies, the existing hair curling shell 40-2 has air guide ribs at the air outlet, and the gaps between the air guide ribs need to be matched with the inner tube 40-1; or the existing hair curling shell 40-2 is spliced ​​from multiple arc-shaped plates 40-21, resulting in a complex structure and difficult assembly. In this embodiment, the hair curling shell 40-2 does not have air guide ribs, making it easier to manufacture as a single piece, reducing manufacturing requirements and related processes. When users use the product to curl their hair, the one-piece hair curling shell 40-2 makes it easier to control the air outlet gap size, allowing the hair to flow with the airflow and adhere to the outer wall of the hair curling shell 40-2 before being blown out. This prevents hair from tangling during curling, providing a better user experience. Furthermore, the hair curling shell 40-2 of this application is made of metal, which has good thermal conductivity, improving the speed of hair heating and styling, and making the styling effect more durable, meeting the needs of most users for styling results.

[0383] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0384] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
