Description

Locking structure, accessories, hair dryer and shaping equipment Technical Field

[0001] This application relates to the technical field of hair styling tools, specifically to a locking structure, accessories, hair dryer, and styling equipment. Background Technology

[0002] There are many styling tools used daily for hair styling, such as straighteners, curling irons, and curling brushes. Curling irons are used to bend hair into specific shapes and curves. Curling irons are divided into manual and automatic types. Both manual and automatic curling irons include a heated shaft. With a manual curling iron, hair is manually rolled onto the shaft, and after heating for a certain time, the hair is curled. With an automatic curling iron, the hair is wrapped around the shaft by rotation, and similarly, after heating for a certain time, the hair is curled. Manual curling irons require manual curling, making the operation relatively complex, while automatic curling irons require a drive mechanism to rotate the shaft, increasing manufacturing costs. Technical issues

[0003] In view of this, this application provides a locking structure, an accessory, a hair dryer, and a styling device, aiming to solve the problems of traditional manual curling irons requiring manual curling and relatively complicated operation steps, while automatic curling irons require a drive component to drive the body to rotate, which increases manufacturing costs. Technical solutions

[0004] To achieve the above objectives, an appendix to this application includes:

[0005] Support base;

[0006] An adjusting member is rotatably disposed at one end of the support base along its axial direction to have a first adjusting position and a second adjusting position;

[0007] Multiple air guides are arranged sequentially along the circumferential direction on the outer periphery of the support base. All of the multiple air guides can move relative to the support base, so that an air guide hole can be formed between each two adjacent air guides.

[0008] An adjusting member is rotatably disposed outside the support base and located at one end of the plurality of air guide members, so as to have a first adjusting position and a second adjusting position;

[0009] The support base is provided with a driving part, and at least one of the air guides is provided with a mating part, wherein the driving part is configured to cooperate with at least one of the mating parts;

[0010] When the adjusting member rotates to switch between the first adjusting position and the second adjusting position, under the cooperation of the driving part and at least one of the mating parts, the plurality of air guides can be driven to move relative to the support to change the orientation of the plurality of air guide holes formed, so that the airflow flowing out of the plurality of air guide holes can switch from one of forward flow and one of reverse flow along the outer surface of the plurality of air guides to the other.

[0011] This application also provides a molding device, including the aforementioned accessories. Beneficial effects

[0012] The accessories provided in this application include a support base, an adjusting component, and multiple air guides. The support base can be connected to devices such as hair dryers, allowing the accessories to be better installed on the hair dryer for curling. The support base also provides multiple air guides for mounting. The multiple air guides are arranged on the outer periphery of the support base. By forming air guide holes between two adjacent air guides, the airflow blown from the hair dryer can flow from the support base to the multiple air guide holes and be discharged through the multiple air guide holes. The airflow can flow along the outer periphery of the multiple air guides to form a ring-shaped airflow. Therefore, when in contact with hair, the hair will curl around the outer periphery of the multiple air guides in the direction of the airflow. Moreover, since the multiple air guides are movable, the rotation of the adjusting component can drive the multiple air guides to move, thereby adjusting the orientation of the air guide holes. Specifically, when the adjusting member rotates to switch between the first and second adjusting positions, under the cooperation of the driving part and at least one mating part, multiple air guides can be driven to move relative to the support base to change the orientation of the multiple air guide holes formed. This allows the airflow from the multiple air guide holes to switch between flowing in one direction and flowing in the opposite direction along the outer surface of the multiple air guides, thereby achieving bidirectional curling. The accessory can better meet various curling modes, resulting in a better user experience. Moreover, since the air guide holes are formed on the outer surface of the accessory, it is easier to observe the direction of airflow, making it easier for users to find the curling direction and making operation more convenient.

Example 1

[0054] This application provides an accessory 100a. Specifically, please refer to Figures 1 to 3. In this embodiment, accessory 100a includes a support base, an adjusting member 62a, and multiple air guide members 7a. The multiple air guide members 7a are arranged sequentially along the outer periphery of the support base in a circumferential direction. All multiple air guide members 7a can move relative to the support base, so that an air guide hole 8a can be formed between each pair of adjacent air guide members 7a. The adjusting member 62a is rotatably disposed outside the support base and located at one end of the multiple air guide members 7a, so as to have a first adjusting position and a second adjusting position. The support base is provided with a driving part 611. a. At least one air guide 7a is provided with a mating part 72a, and the driving part 611a is provided in cooperation with at least one mating part 72a. When the adjusting part 62a rotates to switch between a first adjusting position and a second adjusting position, under the cooperation of the driving part 611a and at least one mating part 72a, multiple air guides 7a can be driven to move relative to the support to change the orientation of the multiple air guide holes 8a formed, so that the airflow flowing out of the multiple air guide holes 8a can switch from one of forward flow and one of reverse flow along the outer surface of the multiple air guides 7a to the other.

[0055] In this embodiment, the support base can be used to connect with devices such as hair dryers, so that the accessory 100a can be better installed on the hair dryer for curling. The support base can also provide multiple air guides 7a for installation. The multiple air guides 7a are arranged on the outer periphery of the support base. By forming air guide holes 8a between two adjacent air guides 7a, the airflow blown from the hair dryer can flow from the support base to the multiple air guide holes 8a and be discharged through the multiple air guide holes 8a. The airflow can flow along the outer periphery of the multiple air guides 7a to form an annular airflow. So when it comes into contact with hair, the hair will curl around the outer periphery of the multiple air guides 7a in the direction of the airflow. Moreover, since the multiple air guides 7a are movable, the rotation of the adjusting member 62a can drive the multiple air guides 7a to move, thereby adjusting the orientation of the air guide holes 8a. Specifically, when the adjusting member 62a rotates to switch between the first adjusting position and the second adjusting position, under the cooperative action of the driving part 611a and at least one cooperating part 72a, multiple air guides 7a can be driven to move relative to the support seat to change the orientation of the multiple air guide holes 8a formed, so that the airflow from the multiple air guide holes 8a can switch from one to the other along the outer surface of the multiple air guides 7a, so as to achieve bidirectional curling. The accessory 100a can better meet multiple curling modes and provide a better user experience. Moreover, the air guide holes 8a are formed on the outer surface of the accessory 100a, making it easier to observe the direction of airflow, and the user can more easily find the curling direction, making the operation more convenient.

[0056] It is understandable that there are many ways to achieve lateral deflection by adjusting multiple air guides 7a through adjusting member 62a. In one embodiment, the rotation of adjusting member 62a can drive multiple air guides 7a to move one by one, so as to form multiple air guide holes 8a one by one.

[0057] Preferably, the rotation of the adjusting member 62a can drive multiple air guides 7a to move synchronously, thereby forming multiple air guide holes 8a simultaneously, resulting in higher operating efficiency. Specifically, multiple driving units 611a are provided, and each air guide 7a is provided with a mating part 72a. The multiple driving units 611a and the mating parts 72a on the multiple air guides 7a are arranged in a one-to-one correspondence. By rotating the adjusting member 62a, the multiple air guides 7a can rotate together. Under the action of the cooperation between each driving unit 611a and the corresponding mating part 72a, the multiple air guides 7a are driven to deflect synchronously, thereby forming multiple air guide holes 8a simultaneously. This makes the airflow around the accessory 100a more uniform, and the efficiency during hair curling is also higher.

[0058] Furthermore, the two ends of each air guide 7a are rotatably mounted on the support base and the adjusting member 62a respectively. The adjusting member 62a rotates under the action of external force, which can drive multiple air guides 7a to rotate together around the central axis of the support base. Under the cooperation of multiple driving parts 611a and multiple mating parts 72a, each air guide 7a can rotate along its own rotation axis, so that each air guide 7a can rotate relative to the support base to switch the orientation of the air outlet. The structure is simple and the adjustment is convenient.

[0059] Specifically, referring to Figures 1, 2, and 4, the support base includes a mounting base 1a and a support shaft 61a with one end mounted on the mounting base 1a. An adjusting member 62a is located at the other end of the support shaft 61a. The mounting base 1a is generally cylindrical, and the support shaft 61a is located at one end of the mounting base 1a and connected to it. The support shaft 61a is also generally cylindrical. The support shaft 61a and the mounting base 1a can be integrally formed or detachably connected. Multiple air guides 7a are rotatably connected to the outer periphery of the support shaft 61a. The adjusting member 62a rotates under the action of external force. Under the cooperative action of multiple driving parts 611a and multiple mating parts 72a, the multiple air guides 7a are driven to rotate together relative to the support shaft 61a around their own rotation axis. When the adjusting member 62a rotates under the action of an external force, since each air guide 7a is connected to the adjusting member 62a, it causes the multiple air guides 7a to tend to rotate together around the central axis of the support shaft 61a. Furthermore, under the combined action of the multiple driving parts 611a and the multiple mating parts 72a, the rotation of the multiple air guides 7a in the circumferential direction along the support shaft 61a is restricted, so that each air guide 7a can rotate on its own axis, thereby changing the orientation of the formed air guide holes 8a.

[0060] It is understood that, in one embodiment, the adjusting member 62a can be driven to rotate by a driver, which is more intelligent and less labor-intensive. Preferably, the adjusting member 62a is manually rotated, which is simpler in structure and lower in cost.

[0061] Further, referring to Figures 3 and 4, the adjusting component 62a includes an adjusting disc 621a and an adjusting handle 622a protruding from the side of the adjusting disc 621a facing away from the support shaft 61a. The adjusting disc 621a is connected to the support shaft 61a, specifically by screws, allowing the adjusting disc 621a to rotate relative to the support shaft 61a. Multiple air guides 7a are rotatably connected to the adjusting disc 621a. The adjusting disc 621a is generally disc-shaped, and its diameter is larger than that of the support shaft 61a. The adjusting disc 621a can cover the ends of multiple air guides 7a, facilitating their connection. Preferably, the adjusting handle 622a is generally cylindrical, and its outer periphery has a concave-convex structure or a frosted structure to increase friction and reduce effort during adjustment.

[0062] The rotation direction of the adjusting member 62a can be opposite to or the same as the direction of the airflow. Preferably, the rotation direction of the adjusting member 62a is the same as the direction of the airflow. Specifically, when the adjusting member 62a is subjected to an external force, it rotates in the forward direction, moving from the second adjusting position toward the first adjusting position, so that the airflow from the multiple air guide holes 8a flows in the forward direction along the outer surface of the multiple air guide members 7a; when the adjusting member 62a is subjected to an external force, it rotates in the reverse direction, moving from the first adjusting position toward the second adjusting position, so that the airflow from the multiple air guide holes 8a flows in the reverse direction along the outer surface of the multiple air guide members 7a. The forward rotation can be set to clockwise rotation, then the reverse rotation is counterclockwise rotation; if the forward rotation is counterclockwise rotation, then the reverse rotation is clockwise rotation.

[0063] Furthermore, as shown in Figures 5 to 7, the two ends of each air guide 7a are rotatably connected to the support base and the adjusting member 62a, respectively. Each air guide 7a has a first side and a second side that are arranged opposite to each other along the circumference of the support shaft 61a. Multiple air guides 7a are arranged adjacent to each other, that is, along the circumference of the support shaft 61a, the second side of the previous air guide 7a is arranged adjacent to the first side of the next air guide 7a, so that an air guide hole 8a can be formed between them. Furthermore, the rotation axis of each air guide 7a is located between its first side and second side. When the adjusting plate 621a rotates, under the cooperation of each driving part 611a and each mating part 72a, each air guide 7a can rotate relative to the support base and the adjusting part 62a, so that when one of the first side and the second side of each air guide 7a moves closer to the support shaft 61a, the other side moves away from the support shaft 61a. In particular, in two adjacent air guides 7a, the aforementioned air guide hole 8a is formed between the second side of one air guide 7a and the first side of the other air guide 7a. By adjusting the rotation of each air guide 7a, the airflow direction of two adjacent air guides 7a is indicated by the dashed arrows in Figures 6 and 7. The two adjacent air guides 7a are set as the first air guide 7a and the second air guide 7a, respectively. When the adjusting member 62a rotates in the forward direction, the second side of the first air guide 7a is positioned above the first side of the second air guide 7a, so that the airflow blown out from the air guide hole 8a can flow along the outer surface of the second air guide 7a to form an airflow flowing in the forward direction. When the adjusting member 62a rotates in the reverse direction, the first side of the second air guide 7a is positioned above the second side of the first air guide 7a, so that the airflow blown out from the air guide hole 8a can flow along the outer surface of the first air guide 7a to form an airflow flowing in the reverse direction.

[0064] Furthermore, the support shaft 61a is hollow and connected to the support base. Multiple air outlets are provided on the circumferential side of the support shaft 61a, and these outlets are connected to multiple air guide holes 8a in a corresponding manner. This allows the airflow from the hair dryer to enter the support shaft 61a through the support base and be evenly blown out from the multiple air outlets of the support shaft 61a, resulting in more uniform airflow at each air guide hole 8a and a better curling effect. Moreover, in the first or second adjustment position, one circumferential side of each air guide 7a is in contact with the support shaft 61a, while the other circumferential side of each air guide 7a is spaced apart from the support shaft 61a to form air guide holes 8a, which are connected to the corresponding air outlets. Through each air guide 7a, the airflow can better flow along the inner wall of the air guide 7a towards the air guide holes 8a, resulting in a better airflow effect.

[0065] To improve the adjustment effect of the multiple air guides 7a, preferably, one of the driving part 611a and the mating part 72a is configured as a transmission boss 721a, and the other is configured as a transmission groove 6111a. The transmission boss 721a is engaged in the transmission groove 6111a and can rotate relative to the transmission groove 6111a. The small stroke allows for better control of the angle of the multiple air guides 7a, thereby better control of the air outlet direction of the air guide hole 8a.

[0066] More preferably, as shown in Figures 6 and 7, the drive unit 611a includes a transmission groove 6111a provided on the peripheral side of the support shaft 61a, and the mating part 72a includes a transmission boss 721a protruding from the inner side of each air guide 7a. The cross-sectional shape of the transmission groove 6111a and the cross-sectional shape of the transmission boss 721a are adapted to each other and are both arranged in an arc shape, so that when the adjusting member 62a rotates, the transmission groove 6111a and the transmission boss 721a can better cooperate, so that each air guide 7a can rotate.

[0067] Specifically, as shown in Figures 4 and 5, each air guide component 7a includes an air guide blade 71a, which extends axially along the support shaft 61a and is arranged in an arc shape, with the curvature of each air guide blade 71a matching that of the support shaft 61a. Each air guide component 7a is provided with multiple transmission bosses 721a, which are spaced apart axially along the support shaft 61a. Each transmission groove 6111a is arranged axially through the support shaft 61a, allowing each air guide blade 71a to engage with the support shaft 61a at all points, resulting in a more uniform force application to the air guide blades 71a and more balanced movement at all points, thus leading to more uniform airflow.

[0068] Among them, rotating convex shafts are provided at both ends of the axial direction of the air guide blade 71a, and the two rotating convex shafts form the rotating shaft of the air guide blade 71a. Multiple elongated holes are provided on the adjusting disk 621a. The multiple elongated holes are distributed at intervals along the circumference of the adjusting disk 621a and are all arranged to extend radially along the adjusting disk 621a. The rotating convex shafts at the upper end of the multiple air guide blades 71a are inserted into the multiple elongated holes one by one.

[0069] During assembly, each guide vane 71a can be inserted into the outer side of the support shaft 61a from top to bottom, so that the multiple transmission bosses 721a on each guide vane 71a can be inserted into the corresponding transmission grooves 6111a. When the rotating cam shaft is inserted into the corresponding mounting hole on the mounting base 1a, it indicates that each guide vane 71a is installed in place. The assembly is simple and convenient, and it is easy to maintain each guide vane 71a.

[0070] In one embodiment, heating elements, such as heating wires or heating plates, may be provided on the inner and / or outer sides of each support shaft 61a to increase the heat output of each air guide hole 8a, thereby improving the curling efficiency.

[0071] In addition, the accessory 100a also includes a limiting structure, which is used to limit the position of the adjusting member 62a so that the adjusting member 62a can be held in the first adjusting position and the second adjusting position respectively, so that the position of each air guide blade 71a is more stable when curling hair. Specifically, the limiting structure includes a telescopic protrusion provided at the end of the support shaft 61a and two limiting holes provided on the adjusting member 62a. The two limiting holes are connected so that when in the first adjusting position, the telescopic protrusion can be locked in one of the limiting holes, limiting the adjusting member 62a from continuing to rotate in that direction. When the adjusting member 62a is rotated in the opposite direction, the telescopic protrusion can disengage from the limiting hole until the other limiting hole is aligned with the telescopic protrusion and locked in it. Thus, the adjusting member 62a can be limited in both directions to ensure the working state of the multiple air guide blades 71a.

[0072] As for the mounting base 1a, the mounting base 1a can be used to extend at least partially into the docking structure of the hair dryer, so that the accessory 100a can be quickly attached to and detached from the hair dryer.

[0073] When the molding device is set to one of its operating states, the blower is located at the bottom end of the mounting base 1a, meaning that the air outlet of the blower is connected to the bottom opening of the mounting base 1a; the adjusting component 62a and multiple air guides 7a are located at the top end of the mounting base 1a. For ease of explanation, the description of the orientation in this application is based on the molding device in this operating state; other operating states can be adapted accordingly.

[0074] Furthermore, as shown in Figures 2 and 8, the mounting base 1a is also provided with a first locking structure 2a and a second locking structure 3a, and a rotating sleeve 4a is fitted on the outer side of the mounting base 1a. The first locking structure 2a is movably mounted on the mounting base 1a and has a first working position suitable for insertion with the insertion part 201a of the hair dryer to restrict the mounting base 1a from rotating circumferentially relative to the hair dryer, and a second working position disengaged from the insertion part 201a. The first locking structure 2a is provided with a first locking part 22a. The second locking structure 3a is provided on the mounting base 1a and is suitable for locking with the second locking part 202a on the hair dryer to restrict the mounting base 1a from disengaging from the hair dryer axially. The rotating sleeve 4a is rotatably fitted on the outer side of the mounting base 1a and has a locked state and an unlocked state. The rotating sleeve 4a is provided with an unlocking part 41a that cooperates with the first locking part 22a. When the rotating sleeve 4a rotates and switches from the locked state to the unlocked state, the rotating sleeve 4a has a first stroke segment that rotates relative to the mounting base 1a and a second stroke segment that drives the mounting base 1a to rotate together. When it is in the first stroke segment, the first locking structure 2a is driven to move from the first working position to the second working position and is held in the second working position under the cooperation of the unlocking part 41a and the first locking part 22a. When it is in the second stroke segment, the second locking structure 3a is driven to disengage from the second locking part 202a.

[0075] The first locking structure 2a is mainly used to restrict the relative movement of the mounting base 1a and the hair dryer in the circumferential direction. Preferably, as shown in FIG2, the first locking structure 2a includes a locking plate 21a, which has a travel along the axial direction of the mounting base 1a. The rotating sleeve 4a rotates relative to the mounting base 1a and, under the action of the unlocking part 41a and the first locking part 22a, drives the locking plate 21a to reciprocate along the axial direction of the mounting base 1a. A mounting groove is provided on the outer peripheral side of the mounting base 1a, and the locking plate 21a is accommodated in the mounting groove. The outer surface of the locking plate 21a is approximately on the same surface as the outer peripheral side of the mounting base 1a, or the locking plate 21a protrudes slightly from the mounting groove and does not interfere with the rotation of the rotating sleeve 4a. By moving the locking plate 21a axially, it can be inserted into or separated from the insertion part 201a of the hair dryer, thereby allowing the mounting base 1a and the hair dryer to be relatively fixed or rotated relative to each other in the circumferential direction. This makes the engagement between the locking plate 21a and the hair dryer more stable and reliable when the locking plate 21a is in the first position, ensuring that the accessory 100a will not wobble relative to the hair dryer.

[0076] It is understood that there are many ways to adjust the axial movement of the locking plate 21a. Preferably, the rotation of the rotating sleeve 4a can be converted into axial displacement of the locking plate 21a. Specifically, referring to Figures 8 and 9, the unlocking part 41a includes a first wedge-shaped boss 411a disposed on the inner side of the rotating sleeve 4a, and the first locking part 22a includes a second wedge-shaped boss 221a disposed on the locking plate 21a. The first wedge-shaped boss 411a and the second wedge-shaped boss 221a are wedge-shapedly engaged. When the rotating sleeve 4a is in the locked state, the first wedge-shaped boss 411a and the second wedge-shaped boss 221a are misaligned along the axial direction of the mounting base 1a. Furthermore, when the rotating sleeve 4a is in the locked state, the ends of the first wedge-shaped boss 411a and the second wedge-shaped boss 221a that are close to each other are provided with chamfers to facilitate the wedge-shaped engagement of the first wedge-shaped boss 411a and the second wedge-shaped boss 221a. When the rotating sleeve 4a switches from the locked state to the unlocked state, the first wedge-shaped boss 411a abuts against the second wedge-shaped boss 221a along the wedge insertion direction, driving the locking plate 21a to move away from the hair dryer along the axial direction of the mounting base 1a, so that the first locking structure 2a can disengage from the insertion part 201a of the hair dryer, thereby unlocking the mounting base 1a in the circumferential direction.

[0077] Furthermore, the first locking structure 2a also includes an elastic reset member, which connects the locking plate 21a and the mounting base 1a. When the unlocking part 41a and the first locking part 22a are separated, the locking plate 21a automatically resets from the second working position to the first working position, avoiding the need for manual readjustment of the locking plate 21a for locking, thus simplifying operation. The elastic reset member can be configured as a telescopic spring. When the rotating sleeve 4a rotates under external force (such as manually), the first wedge-shaped boss 411a abuts against the bottom of the second wedge-shaped boss 221a, driving the locking plate 21a upwards and compressing the telescopic spring, allowing the locking plate 21a to separate from the insertion part 201a. When the first wedge-shaped boss 411a and the second wedge-shaped boss 221a are completely misaligned in the vertical direction, the first wedge-shaped boss 411a no longer abuts against the second wedge-shaped boss 221a. Under the elastic extension force of the telescopic spring, the locking plate 21a can be pushed downward, so that the locking plate 21a can be inserted into the plug part 201a on the hair dryer again to be in a locked state.

[0078] It is understandable that when the rotating sleeve 4a enters the second stroke segment, in order to allow the mounting base 1a and the rotating sleeve 4a to rotate together, in one embodiment, a driving part 611a may be provided on the rotating sleeve 4a, and a transmission part may be provided on the mounting base 1a. The driving part 611a abuts against and pushes the transmission part, thereby driving the mounting base 1a to rotate together under the pushing action of the rotating sleeve 4a. The driving part 611a is a first protrusion provided on the inner sidewall of the rotating sleeve 4a, and the transmission part is a second protrusion provided on the outer sidewall of the mounting base 1a. When the locking plate 21a is in the second working position, the first protrusion abuts against one side of the second protrusion along the circumference of the mounting base 1a. When the rotating sleeve 4a is continuously subjected to external force to rotate, the first protrusion pushes the second protrusion, causing the mounting base 1a and the rotating sleeve 4a to rotate together until the second locking structure 3a unlocks the second locking part 202a of the hair dryer.

[0079] In another embodiment, an elastic limiting member 5a is also included, which abuts against the mounting base 1a and the rotating sleeve 4a. When the first locking structure 2a moves to the second working position, the elastic limiting member 5a is in an elastic energy storage state and is located at the end of its elastic movement stroke. When the rotating sleeve 4a continues to rotate under the action of an external force to enter the second stroke segment, the mounting base 1a can be driven to rotate together under the abutting action of the elastic limiting member 5a, so that the second locking structure 3a is suitable for disengaging from the second locking part 202a. When the external force on the rotating sleeve 4a is removed, the rotating sleeve 4a can rotate in the opposite direction under the action of the elastic restoring force of the elastic limiting member 5a, so that the first locking structure 2a can return to the first working position. The elastic limiting member 5a not only allows the mounting base 1a and the rotating sleeve 4a to rotate together in the second stroke, but also allows the rotating sleeve 4a and the locking plate to automatically reset after the mounting base 1a is removed from the hair dryer, making operation more convenient and easier to reinstall the mounting base 1a on the hair dryer.

[0080] More preferably, as shown in Figure 8, the elastic limiting member 5a is a torsion spring 51a. A first limiting rib 11a protrudes from the peripheral sidewall of the mounting base 1a, and a second limiting rib 42a protrudes from the inner side of the rotating sleeve 4a. The first limiting rib 11a and the second limiting rib 42a are spaced apart along the circumference of the mounting base 1a, and the two torsional arms of the torsion spring 51a abut against the first limiting rib 11a and the second limiting rib 42a, respectively. When the rotating sleeve 4a rotates to complete the first stroke segment, the second limiting rib 42a torsionally compresses the torsion spring 51a. When the first stroke segment is completely completed, the torsion spring 51a no longer torsionalally stores energy, and can then push the first limiting rib 11a, thereby driving the mounting base 1a to rotate as well.

[0081] Of course, the methods for driving the mounting base 1a and the rotating sleeve 4a to rotate together include, but are not limited to, those described above. In other embodiments, the two methods described above can be combined to ensure a more accurate and reliable driving position for the mounting base 1a.

[0082] The second locking structure 3a is mainly used to limit the relative position of the mounting base 1a and the blower in the axial direction. Preferably, as shown in Figures 2 and 8, the second locking structure 3a includes a limiting groove 31a provided on the peripheral side wall of the mounting base 1a. The mounting base 1a is hollow and open on the side facing the blower. At least a portion of the mounting base 1a can extend into the blower, so that the limiting groove 31a can engage with the limiting protrusion of the blower. A clearance notch 32a is provided on the side of the limiting groove 31a facing the blower, so that the first groove wall of the limiting groove 31a with the clearance notch 32a is suspended along the circumference of the mounting base 1a. The limiting protrusion of the blower can extend into the limiting groove 31a from the clearance notch 32a, and after the mounting base 1a and the blower rotate relative to each other, the limiting protrusion can engage with the first groove wall, thereby restricting the relative movement of the mounting base 1a and the blower in the axial direction.

[0083] The second locking structure 3a can be provided in multiple ways, and the multiple second locking structures 3a are arranged at intervals along the circumference of the mounting base 1a. The hair dryer can be provided with multiple second locking parts 202a, and the connection between the mounting base 1a and the hair dryer is more stable and reliable by the multiple second locking structures 3a engaging with the multiple second locking parts 202a one by one.

[0084] Furthermore, an annular boss 12a extending circumferentially is provided on the outer periphery of the mounting base 1a to divide the mounting base 1a into a first connecting segment and a second connecting segment. A rotating sleeve 4a is fitted onto the outer periphery of the first connecting segment. A first locking structure 2a is provided on the first connecting segment and can at least partially extend into the first connecting segment. A second locking structure 3a is provided on the second connecting segment. Specifically, the second connecting segment extends at least partially or completely into the hair dryer, such that the annular boss 12a abuts against the mating end of the hair dryer. When installing accessory 100a, the locking plate 21a can be aligned with the plug portion 201a on the hair dryer, and then the second connecting section can be inserted downwards into the hair dryer. When the annular boss 12a abuts against the mating end of the hair dryer, the mounting base 1a can be rotated. When the mounting base 1a can no longer rotate, the limiting protrusion inside the hair dryer is completely locked in the corresponding limiting groove 31a, so that accessory 100a can be completely fixed on the hair dryer. The assembly is simple and convenient. When disassembling accessory 100a, the rotating sleeve 4a is rotated. When the mounting base 1a rotates together and can no longer rotate, the entire accessory 100a can be completely disassembled. The disassembly operation is also very simple.

[0085] In addition, a plurality of first locking protrusions 13a are provided on the outer periphery of the mounting base 1a. The plurality of first locking protrusions 13a are arranged at intervals along the circumference of the mounting base 1a, and are all offset from the locking plate 21a in the circumferential direction. A plurality of second locking protrusions 43a are provided on the inner side of the rotating sleeve 4a. When in the locked state, the plurality of first locking protrusions 13a and the plurality of second locking protrusions 43a are engaged in a one-to-one manner to prevent the rotating sleeve 4a from disengaging from the end of the mounting base 1a near the accessory 100a. The rotating sleeve 4a is generally cylindrical with open ends. The opening at the end of the rotating sleeve 4a facing away from the blower has an inwardly extending edge to abut downward against the end of the mounting base 1a. The second locking protrusions 43a abut against the first locking protrusions 13a upward, thereby positioning the rotating sleeve 4a on the mounting base 1a at its upper axial limit. Moreover, when multiple first protrusions 13a and multiple second protrusions 43a abut against each other, the rotation of the rotating sleeve 4a can be guided, making the rotating sleeve 4a more stable during rotation.

[0086] This application also provides a styling device, which includes the aforementioned accessory 100a and a hair dryer. The accessory 100a and the hair dryer can be quickly disassembled and assembled, making them more convenient to use. Specifically, the hair dryer includes a blower body, and a plug-in portion 201a and a second locking portion 202a disposed on the blower body. The plug-in portion 201a is adapted to cooperate with the first locking structure 2a of the accessory 100a to restrict the accessory 100a from moving circumferentially relative to the hair dryer. The second locking portion 202a is adapted to cooperate with the second locking structure 3a of the accessory 100a to restrict the accessory 100a from moving radially relative to the hair dryer. This makes the connection between the accessory 100a and the hair dryer stable and reliable, while also making disassembly and assembly more convenient.

[0087] Preferably, as shown in Figure 10, the main body of the fan includes a cylindrical air outlet structure 200a, a plug-in portion 201a including a plug-in groove 2011a on the inner wall of the air outlet structure 200a, and a second locking portion 202a including a limiting protrusion 2021a on the inner wall of the air outlet structure 200a. The air outlet structure 200a is connected to the mounting base 1a, and the airflow blown out by the fan can enter the accessory 100a from the mounting base 1a. The specific disassembly and assembly method of the accessory 100a has been described above and will not be repeated here.

[0088] The air outlet structure 200a can be integrated with the hair dryer. Alternatively, the air outlet structure 200a can be detachably mounted on the hair dryer.

[0089] Example 2

[0090] Referring to Figures 11 to 16, this application provides an accessory 100b, a hair dryer, and a styling device. The styling device includes the accessory 100b and a hair dryer. The accessory 100b is adapted for use with the hair dryer, enabling the styling device to better achieve hair styling. It should be noted that the accessory 100b, hair dryer, and styling device in this specific embodiment 2 can be the accessory, hair dryer, and styling device described in specific embodiment 1 above, or it can be other accessories, hair dryers, and styling devices different from those in specific embodiment 1 above.

[0091] Specifically, please refer to Figures 11 to 13. In this embodiment, accessory 100b includes a base, a hair styling rod 1b, multiple hair styling blades 2b, and a heating element 3b. One end of the hair styling rod 1b is disposed on the base and is hollow. Multiple hair styling blades 2b are disposed on the base and surround the outer periphery of the hair styling rod 1b. An air passage is formed between the multiple hair styling blades 2b and the hair styling rod 1b. Each pair of adjacent hair styling blades 2b is spaced apart to form an air outlet. Multiple air outlets are connected to the air passage, and multiple hair styling blades 2b can move relative to the hair styling rod 1b to switch the orientation of the multiple air outlets. The air passage and the inner cavity of the hair styling rod 1b together form an airflow passage. The heating element 3b is disposed in the airflow passage and / or on the wall of the passage forming the airflow passage.

[0092] In this embodiment, the base is used to support the hair styling iron 1b and multiple hair styling blades 2b, and is connected to the hair dryer via the base; the hair styling iron 1b is hollow, and the heating element 3b can be disposed on the inner and / or outer side of the hair styling iron 1b, thereby heating the hair styling iron 1b, as well as the air and / or components around the hair styling iron 1b; multiple hair styling blades 2b are arranged around the outer periphery of the hair styling iron 1b, and an air passage is formed between them; and air outlets are formed between each pair of adjacent hair styling blades 2b at intervals. The airflow blown from the hair dryer can enter the air passage through the inner side of the hair styling iron 1b and be blown out from the multiple air outlets to follow the multiple hair styling blades. The outer peripheral surface of the blade 2b flows to form an annular airflow along the circumference of the multiple hair styling blades 2b. This allows the hair to curl around the outside of the multiple hair styling blades 2b along the airflow direction when the accessory 100b is close to the hair, thus achieving a curling effect. Furthermore, the airflow exiting the hair dryer is reheated by the heating element 3b when it enters the airflow channel, ensuring the temperature of the airflow when it exits from the multiple air outlets. Moreover, the heating element 3b continuously provides heating when the hair is curled around the outside of the multiple hair styling blades 2b, which can better avoid heat loss and reach the ideal styling temperature better and faster. Therefore, it can better meet the user's styling needs and has higher styling efficiency.

[0093] The hair styling stick 1b is roughly cylindrical in shape, with its axis extending laterally. It should be noted that when the accessory 100b is in normal use, the hair styling stick 1b's axis is vertical, so the aforementioned "lateral" refers to the vertical direction. Unless otherwise specified, all descriptions of orientation in this application shall be taken as such.

[0094] Multiple arc-shaped grooves may be provided on the outer periphery of the hair styling tool 1b, each groove extending through the hair styling tool 1b along its axial direction. The multiple grooves are evenly spaced along the circumference of the hair styling tool 1b, and the number corresponds to the number of multiple hair styling blades 2b. At least a portion of the multiple hair styling blades 2b may be connected within the multiple grooves. Through holes are formed on the groove walls of each groove, connecting the inner and outer sides of the hair styling tool 1b, allowing the airflow from the hair dryer to enter the inner side of the hair styling tool 1b, pass through the multiple through holes to enter the air passage, and finally exit from the multiple air outlets.

[0095] Referring to Figures 12 and 13, each hair styling blade 2b is arc-shaped and matches the shape of the hair styling stick 1b. An adjustment cover 9b is provided at the upper end of the hair styling stick 1b. Rotating protrusions are provided at both the upper and lower ends of each hair styling blade 2b. The rotating protrusions at the upper end of each hair styling blade 2b are rotatably connected to the adjustment cover 9b. A first connecting seat 4b is provided at the lower end of the hair styling stick 1b, and the rotating protrusions at the lower end of each hair styling blade 2b are rotatably connected to the first connecting seat 4b, allowing each hair styling blade 2b to rotate relative to the hair styling stick 1b. Furthermore, multiple limiting protrusions are provided on the inner side of each hair styling blade 2b. These limiting protrusions are spaced apart along the vertical direction to engage with corresponding grooves, allowing airflow to pass through the gaps between the limiting protrusions and exit from the corresponding air outlet. When the air outlets of multiple hair styling blades 2b are all facing one side of the circumference of the hair styling iron 1b, for example, the hair can be rolled up clockwise. By adjusting the rotating cover 9b, multiple hair styling blades 2b can be driven to rotate together. Under the cooperation of the corresponding limiting protrusions and grooves, each hair styling blade 2b can rotate around the central axis of its own limiting protrusion, so that each hair styling blade 2b can be flipped, and the orientation of each air outlet changes, causing the airflow to blow in the opposite direction. At this time, the hair can be rolled up counterclockwise, so that the accessory 100b can achieve bidirectional hair curling, making the hair curling operation more convenient.

[0096] It is understood that the heating element 3b can be configured as a heating plate, heating wire, or heating rod 31b, etc. The heating element 3b can be located on the inner and / or outer side of the hair styling tool 1b, or it can be located on the inner side of one or more hair styling blades 2b. This allows the airflow to be reheated by the heating element 3b along its path after entering the accessory 100b, compensating for heat loss and ensuring optimal outlet air temperature.

[0097] Preferably, as shown in Figures 12 and 13, the heating element 3b is disposed inside the hair styling tool 1b. The heating element 3b includes an electrical connection structure disposed on the base and a heating rod 31b electrically connected to the electrical connection structure. One end of the heating rod 31b is connected to the base, and the other end extends into the hair styling tool 1b. More preferably, the heating rod 31b is located in the middle of the hair styling tool 1b and is coaxially arranged with the hair styling tool 1b. The heating rod 31b extends along the axial direction of the hair styling tool 1b, and the electrical connection structure is located on the outside of the hair styling tool 1b. The electrical connection structure is electrically connected to the docking part on the hair dryer to provide the electrical energy required for the heating rod 31b to generate heat.

[0098] Furthermore, referring to Figures 14 and 15, the electrical connection structure includes a heating ring 32b and multiple electrical pins 33b disposed on the heating ring 32b. The heating ring 32b is arranged around the outer periphery of the heating rod 31b to accommodate the multiple electrical pins 33b. The multiple electrical pins 33b are spaced apart circumferentially along the heating rod 31b and are suitable for electrical connection with the docking socket on the device body, so that the heating rod 31b can be electrically connected to the device body of the hair dryer, thereby generating heat. The multiple electrical pins 33b can be used for conductivity, temperature control, and identification, respectively, so that the temperature of the heating rod 31b is more suitable when the accessory 100b is in use.

[0099] Furthermore, the base includes a first connecting seat 4b and a second connecting seat 5b connected together. The first connecting seat 4b is connected to one end of multiple hair-drying blades 2b and is arranged around the outer periphery of the heating ring 32b. The first connecting seat 4b and the heating ring 32b can be connected by screws or bolts. One end of the second connecting seat 5b is rotatably sleeved on the inner side of the heating ring 32b, and the other end extends out of the heating ring 32b. Multiple electric pins 33b are arranged around the outer periphery of the second connecting seat 5b, and the heating rod 31b is disposed on the second connecting seat 5b. One end of the second connecting seat 5b is connected to the heating ring 32b, and the other end of the second connecting seat 5b can be adapted to be connected to the main body of the device, thereby detachably installing the entire accessory 100b onto the main body of the device and simultaneously fixing the position of the heating rod 31b.

[0100] In this embodiment, the upper end of the first connecting seat 4b is used to mount multiple hair-styling blades 2b. Airflow can pass through the second connecting seat 5b, the electrical connection structure, and the first connecting seat 4b, and then be blown out from the air outlet between the multiple hair-styling blades to form a curling airflow. The electrical connection structure is located inside the first connecting seat 4b. The electrical connection structure electrically connects the heating rod 31b and the power supply components inside the hair dryer, or it can be used to electrically connect a temperature sensor or temperature controller, etc., so that the electrical components inside the accessory 100b can work better. The second connecting seat 5b is used to connect the accessory 100b and the hair dryer, so that the accessory 100b can be easily disassembled and assembled with the hair dryer. Moreover, the second connecting seat 5b is set to be rotatable relative to the electrical connection structure, so that the accessory 100b can be disassembled and assembled by rotating the second connecting seat 5b, while ensuring that the electrical connection structure does not rotate, thus ensuring the reliability of the connection between the electrical connection structure and the docking structure on the hair dryer.

[0101] The first connecting seat 4b is generally arranged in the shape of a cylinder with one end open. The open end of the first connecting seat 4b is used for the power supply connection structure and the second connecting seat 5b to be installed therein. A connecting hole connected to the hair styling stick 1b is also provided at the end of the first connecting seat 4b, so that the airflow can flow from the connecting hole to the multiple hair styling blades 2b.

[0102] Furthermore, as shown in Figures 12 and 13, accessory 100b also includes a floating ring 6b and multiple elastic elements 7b connecting the floating ring 6b and the heating ring 32b. The floating ring 6b is sleeved on the second connecting seat 5b, extending outward from one end of the heating ring 32b. Multiple through holes are provided on the floating ring 6b, and multiple electrical pins 33b can be inserted into these through holes one by one. Under the action of the multiple elastic elements 7b, the floating ring 6b has a first working state where it is close to the heating ring 32b, allowing the multiple electrical pins 33b to extend from the multiple through holes, and a second working state where it is away from the heating ring 32b, causing the multiple electrical pins 33b to retract into the multiple through holes. This ensures that when accessory 100b is removed from the hair dryer, the multiple electrical pins 33b are not exposed, thus better protecting the multiple electrical pins 33b and preventing them from scratching the user. When accessory 100b is installed on the hair dryer, the floating ring 6b can be pushed upward by the contact action of the hair dryer's main body, so that multiple electrical pins 33b can extend out of the floating ring 6b and be inserted into the docking socket of the main body for better conduction.

[0103] Multiple elastic elements 7b can be configured as telescopic springs, and multiple telescopic springs are evenly distributed along the circumference of the heating rod 31b to make the floating ring 6b float more stably.

[0104] As shown in Figures 13 and 15, the second connecting seat 5b includes an outer ring 51b and an inner ring 52b nested together, and multiple connecting ribs 53b connecting the outer ring 51b and the inner ring 52b. The heating rod 31b is fixedly sleeved inside the inner ring 52b, and the bottom end of the inner ring 52b can be closed to prevent the heat on the heating rod 31b from flowing back into the hair dryer. The airflow from the hair dryer can flow into the hair styling rod 1b through the gaps between the multiple connecting ribs 53b, then enter the air passage between the multiple hair styling blades 2b and the hair styling rod 1b through the through holes on the hair styling rod 1b, and finally flow out from the multiple air outlets, so that the airflow can flow better through the heating rod 31b, the heating is more uniform, and the airflow is closer to the multiple air outlets, thus better ensuring the airflow temperature at the multiple air outlets.

[0105] Multiple connecting posts are provided on the upward-facing side of the heating ring 32b, and multiple mounting holes are provided in the first connecting seat 4b. The mounting holes and the multiple connecting posts are arranged in a one-to-one correspondence. Multiple screws or bolts are inserted one-to-one into the mounting holes and the multiple connecting posts to further connect and fix the heating ring 32b and the first connecting seat 4b, ensuring the stability of the heating component 3b.

[0106] Furthermore, the second connecting seat 5b is provided with a first locking part 54b and a second locking part 55b. Specifically, as shown in Figures 12 and 16, both the first locking part 54b and the second locking part 55b are provided on the outer ring sleeve 51b, with the first locking part 54b located above the second locking part 55b. The first locking part 54b is used to rotate in a first direction to lock with the first mating part 321b on the heating ring 32b, and the second locking part 55b is adapted to rotate in a second direction to lock with the second mating part on the equipment body, wherein the first direction and the second direction are opposite. By rotating the second connecting seat 5b, the accessory 100b can be disassembled from the equipment body, and when the accessory 100b is removed from the equipment body, it can be ensured that the second connecting seat 5b will not detach from the heating ring 32b. After accessory 100b is removed from the main body of the equipment, the second connecting seat 5b can be disassembled more easily by rotating it, which makes accessory 100b easier to maintain and makes the disassembly and assembly of accessory 100b more convenient.

[0107] In this embodiment, the first locking part 54b allows the second connecting seat 5b to connect to the electrical connection structure, and the second locking part 55b allows the entire accessory 100b to connect to the hair dryer, making the assembly of the entire accessory 100b and the assembly of the accessory 100b with the hair dryer more convenient. Furthermore, the rotation direction when assembling the second connecting seat 5b with the electrical connection structure is opposite to the rotation direction when connecting the second connecting seat 5b with the hair dryer. Therefore, when the accessory 100b is removed from the hair dryer, the second connecting seat 5b and the electrical connection structure rotate in the locking direction, ensuring the stability of the entire accessory 100b. Moreover, the locking amount of the first locking part 54b and the first mating part 321b is greater than the locking amount of the second locking part 55b and the second mating part, so the second connecting seat 5b will not detach from the electrical connection structure when the accessory 100b is installed on the hair dryer. The assembly of the entire accessory 100b is more convenient and it is easy to detach from the hair dryer. At the same time, it ensures the stability of the electrical connection structure, making the use of the entire accessory 100b more convenient.

[0108] Furthermore, when the floating ring 6b is in the first working state, the second locking part 55b is located inside the floating ring 6b, making the overall structure of the accessory 100b more compact and aesthetically pleasing. When the floating ring 6b is in the second working state, the second locking part 55b is exposed. That is, the floating ring 6b is raised by the pushing action of the main body of the device, thereby exposing the second locking part 55b outside the floating ring 6b, so that the second locking part 55b can extend into the main body of the device to lock and engage with the second mating part inside the main body of the device. After the accessory 100b is removed from the blower, the floating ring 6b is in the second working state. The floating ring 6b protects the second locking part 55b and the multiple electrical pins 33b, making the structure of the accessory 100b more compact and the overall appearance of the accessory 100b more streamlined and smooth. When accessory 100b is installed on the hair dryer, the connection of the hair dryer presses against the floating ring 6b, causing the floating ring 6b to switch to its first working state. This allows multiple electrical pins 33b to extend from the floating ring 6b and insert into the mating slots inside the hair dryer, and also allows the second locking part 55b to extend from the floating ring 6b and enter the hair dryer to lock into the second mating part on the hair dryer. The floating ring 6b better protects the multiple electrical pins 33b and the second locking part 55b, preventing accessory 100b from scratching the user or other objects when it is removed from the hair dryer.

[0109] Furthermore, a limiting part is provided at one end of the floating ring 6b facing away from the heating ring 32b. The limiting part is adapted to be limited and engaged with the third mating part on the main body of the equipment to restrict the floating ring 6b from rotating around its circumference. On the one hand, after the floating ring 6b is limited, the multiple electrical pins 33b can be better aligned with the docking slot on the hair dryer. On the other hand, the floating ring 6b can also be limited from rotating relative to the hair dryer, ensuring that the accessory 100b is more stable during operation.

[0110] Preferably, as shown in FIG16, the limiting part includes a limiting protrusion protruding from the bottom of the floating ring 6b. The limiting protrusion is adapted to be engaged in the limiting groove on the mating surface of the hair dryer, so as to ensure that the accessory 100b can be better connected and fixed to the hair dryer.

[0111] Since the second connector 5b cannot be observed from the outside of the accessory 100b when the accessory 100b is installed on the main body of the equipment, i.e., the floating ring 6b is in the first working state, and since the electrical pin 33b is plugged into the docking socket on the main body of the equipment, the entire accessory 100b cannot be rotated and disassembled during disassembly.

[0112] In one embodiment, the attachment 100b further includes an adjustment component 8b connected to the second connecting seat 5b. The adjustment component 8b is used to drive the second connecting seat 5b to rotate, so that the second locking part 55b on the second connecting seat 5b can be adapted to engage or disengage with the second mating part on the device body, so that the second connecting seat 5b can rotate independently, thereby avoiding the electrical pin 33b from being twisted and damaged.

[0113] It is understood that, in one embodiment, the adjusting component 8b may be configured as a driver to drive the second connecting seat 5b to rotate.

[0114] Preferably, the adjusting component 8b is moved by manual rotation so that the second connecting seat 5b can move together. Specifically, as shown in Figures 13 and 16, the adjusting component 8b includes an adjusting knob 81b and an elastic reset member connecting the adjusting knob 81b and the first connecting seat 4b. At least a portion of the adjusting knob 81b is exposed outside the first connecting seat 4b and has a circumferential travel along the second connecting seat 5b under external force. Rotation of the adjusting knob 81b drives the second connecting seat 5b to rotate together. The structure is simpler and the disassembly operation of the accessory 100b is more convenient.

[0115] The first connecting seat 4b and the floating ring 6b are provided with corresponding elongated holes, which extend circumferentially along the second connecting seat 5b. The adjusting knob 81b is inserted through the two elongated holes and extends out of the first connecting seat 4b for easy operation by the user. The length of the elongated holes can also limit the rotation of the second connecting seat 5b. When the second connecting seat 5b rotates to the point where it can disengage from the hair dryer, the second connecting seat 5b and the floating ring 6b are fully engaged. When the second connecting seat 5b is reset by the elastic reset member to engage with the hair dryer, the first locking part 54b and the first mating part 321b are also in the engaged position.

[0116] Preferably, the adjusting knob 81b is detachably connected to the second connecting seat 5b to facilitate the assembly of the second connecting seat 5b.

[0117] Preferably, the first locking part 54b includes a first notch 541b at the first end of the second connecting seat 5b, the second locking part 55b includes a second notch 551b at the second end of the second connecting seat 5b, and the first mating part 321b includes a first latching protrusion 3211b inside the heating ring 32b. The notch of the first notch 541b and the notch of the second notch 551b are offset from each other in the vertical direction, and the rotation assembly operation is more convenient and simple.

[0118] This application also provides a hair dryer suitable for use with the aforementioned accessory 100b. The hair dryer includes a main body, a docking socket and a second mating part disposed on the main body. The docking socket is adapted to electrically connect with a plurality of electrical pins 33b on the accessory 100b, and the second mating part is adapted to lock into a second locking part 55b on the accessory 100b. This allows the hair dryer to be quickly attached to and detached from the accessory 100b, and provides the accessory 100b with the electrical energy required for the heating element to heat up, resulting in better curling effect and effectively improving curling efficiency.

[0119] Preferably, the second mating part can be configured as a second locking protrusion, which can be locked into the second notch groove 551b from the notch to fix the accessory 100b to the hair dryer. When disassembling, the accessory 100b can be rotated in the opposite direction so that the second locking protrusion can be aligned with the notch of the second notch groove 551b, so that it can be removed. Both disassembly and assembly are relatively convenient.

[0120] This application also provides a styling device, including the aforementioned accessory 100b and the aforementioned hair dryer. The accessory 100b is detachably connected to the hair dryer, which makes the hair styling effect better and the hair styling efficiency higher, and can effectively improve the user experience of the styling device.

[0121] Example 3

[0122] Referring to Figures 17 to 21, this application provides a locking structure 100c and an accessory. It should be noted that the accessory in this specific embodiment 3 can be the accessory in the above-described specific embodiment 1, or it can be another accessory different from that in the above-described specific embodiment 1. Similarly, one or more embodiments in this specific embodiment 3 can be combined with one or more embodiments in the above-described specific embodiment 2, and it should also have the effects possessed by the above embodiments, which will not be elaborated further. The accessory includes the locking structure 100c, which is used to connect and fix the accessory to the hair dryer, making it easy to install and remove the accessory from the hair dryer.

[0123] This application mainly improves the locking structure 100c. Specifically, please refer to Figures 17 to 19. In this embodiment, the locking structure 100c includes a first base 1c, an electrical connection component 2c, and a second base 3c. The first base 1c is adapted to be installed on the air supply component. The electrical connection component 2c is arranged in a ring shape and connected inside the first base 1c. The electrical connection component 2c is provided with a first mating part 23c. The second base 3c is rotatably sleeved on the inner side of the electrical connection component 2c. The second base 3c is provided with a first lock. The second seat 3c has a first locking part 31c and a second locking part 32c. The second seat 3c rotates in a first direction, such that the first locking part 31c locks with the first mating part 23c to connect the second seat 3c and the electrical connection assembly 2c. When the second seat 3c rotates in a second direction, the second locking part 32c is adapted to lock with the second mating part on the main body of the device. The first direction and the second direction are opposite, and the locking amount of the first locking part 31c and the first mating part 23c is greater than the locking amount of the second locking part 32c and the second mating part.

[0124] In this embodiment, the first seat 1c is adapted to be mounted on the air supply assembly. The airflow can pass through the second seat 3c, the electrical connection assembly 2c, and the first seat 1c before being blown out from the air supply assembly to form a curling airflow. The electrical connection assembly 2c is located inside the first seat 1c. The electrical connection assembly 2c can be used to electrically connect the heating element in the accessory and the power supply element in the hair dryer, or it can be used to electrically connect the temperature sensor or temperature controller, etc., so that the electrical components in the accessory can work better. The second seat 3c is used to connect the locking structure 100c and the hair dryer, so that the locking structure 100c can be easily disassembled and assembled with the hair dryer. Moreover, the second seat 3c is configured to be rotatable relative to the electrical connection assembly 2c, so that the locking structure 100c can be disassembled and assembled by rotating the second seat 3c, while ensuring that the electrical connection assembly 2c does not rotate, thus ensuring the reliability of the connection between the electrical connection structure and the docking structure on the hair dryer. In addition, a first locking part 31 is provided on the second seat 3c. c. The second locking part 32c allows the second seat 3c to be connected to the electrical connection component 2c via the first locking part 31c, and the entire locking structure 100c to be connected to the hair dryer via the second locking part 32c, making the assembly of the entire locking structure 100c and the hair dryer more convenient. Moreover, the rotation direction when assembling the second seat 3c with the electrical connection component 2c is opposite to the rotation direction when connecting the second seat 3c with the hair dryer. Therefore, when the locking structure 100c is removed from the hair dryer, the second seat 3c and the electrical connection structure rotate in the direction of locking, which ensures the stability of the entire locking structure 100c. Furthermore, since the locking amount of the first locking part 31c and the first mating part 23c is greater than the locking amount of the second locking part 32c and the second mating part, the second seat 3c will not detach from the electrical connection component 2c when the locking structure 100c is installed on the hair dryer. The entire locking structure 100c is easier to assemble and disassemble with the hair dryer, while ensuring the stability of the electrical connection component 2c, making the entire accessory more convenient to use.

[0125] The first base 1c is generally cylindrical with one end open. The open end of the first base 1c is used for mounting the power supply connection assembly 2c and the second base 3c. The other axial end of the first base 1c is used for mounting the air outlet assembly. A through hole communicating with the air outlet assembly is also provided at the end of the first base 1c, allowing airflow to flow into the air outlet assembly through the through hole. When the accessory is operating normally, the first base 1c is axially oriented vertically, with the air outlet assembly located at the upper end of the first base 1c, and the bottom end of the first base 1c is open. Unless otherwise specified, all descriptions of orientation in this application shall be taken as above.

[0126] As shown in Figures 18 and 19, the electrical connection assembly 2c includes a connecting ring 21c and a plurality of pins 22c disposed on the end face of the connecting ring 21c. The first end of the second seat 3c is sleeved inside the connecting ring 21c, and the second end of the second seat 3c extends out of the connecting ring 21c. The first locking part 31c is disposed at the first end of the second seat 3c, and the second locking part 32c is disposed at the second end of the second seat 3c. The plurality of pins 22c surround the outer periphery of the second seat 3c and can extend out from the first seat 1c. Specifically, the upper end of the connecting ring 21c is provided with multiple connecting posts, and the first seat 1c is provided with multiple mounting holes. Screws or bolts are inserted one by one into the multiple connecting posts and mounting holes to fix the connecting ring 21c in the first mounting seat. The upper end of the second seat 3c is rotatably sleeved on the inner side of the connecting ring 21c and is connected to the first mating part 23c of the connecting ring 21c through the first locking part 31c, thereby installing the second seat 3c in the connecting ring 21c. The lower end of the second seat 3c can protrude from the first seat 1c to connect and engage with the second mating part of the hair dryer through the second locking part 32c. Multiple insertion pins 22c also protrude from the first seat 1c so that after the locking structure 100c is installed on the hair dryer, the multiple insertion pins 22c can be inserted into the docking slots of the hair dryer to make electrical connection with the hair dryer.

[0127] Furthermore, as shown in Figures 19 to 21, the locking structure 100c also includes a floating adjustment member 4c. The floating adjustment member 4c has multiple through holes 42c, and multiple connector pins 22c are correspondingly inserted into each of the multiple through holes 42c. The floating adjustment member 4c is sleeved on the outer periphery of the second base 3c and can move relative to the second base 3c. The floating adjustment member 4c has a first working state close to the connecting ring 21c, where the second locking part 32c and the multiple connector pins 22c are exposed, and a second working state away from the connecting ring 21c, where the floating adjustment member 4c can cover the second locking part 32c and the multiple connector pins 22c. After the accessory is removed from the hair dryer, the floating adjustment member 4c is in the second working state. By covering and protecting the second locking part 32c and the multiple connector pins 22c through the floating adjustment member 4c, the structure of the accessory is more compact, and the overall appearance of the accessory is smoother. When the accessory is installed on the hair dryer, the connection point of the hair dryer presses against the floating adjustment member 4c, causing the floating adjustment member 4c to switch to its first working state. This allows multiple connector pins 22c to extend from the floating adjustment member 4c and insert into the mating slots inside the hair dryer, and also allows the second locking part 32c to extend from the floating adjustment member 4c and enter the hair dryer to lock into the second mating part on the hair dryer. The floating adjustment member 4c better protects the multiple connector pins 22c and the second locking part 32c, making it less likely to scratch the user or other objects when the accessory is removed from the hair dryer.

[0128] Preferably, as shown in Figures 20 and 21, the floating adjustment member 4c includes an adjustment ring 41c and a plurality of elastic members 44c connecting the adjustment ring 41c and the connecting ring 21c. The adjustment ring 41c is sleeved on the outer side of the second end of the second seat 3c, and the plurality of elastic members 44c surround the outer periphery of the second seat 3c and all extend along the axial direction of the adjustment ring 41c. The elastic members 44c can be configured as telescopic springs or elastic rubber, and the telescopic movement of the elastic members 44c allows the adjustment ring 41c to move vertically, switching between a first working state and a second working state.

[0129] Furthermore, a limiting part 43c is provided at one end of the adjusting ring 41c facing away from the connecting ring 21c. The limiting part 43c is adapted to be limited and engaged with the third mating part on the main body of the equipment to restrict the adjusting ring 41c from rotating around its circumference. On the one hand, after the adjusting ring 41c is limited, the multiple plug pins 22c can be better aligned with the docking slot on the blower. On the other hand, the adjusting ring 41c can also be limited from rotating relative to the blower, ensuring that the accessory is more stable during operation.

[0130] Preferably, as shown in FIG21, the limiting part 43c includes a limiting protrusion 431c protruding from the bottom of the adjusting ring 41c. The limiting protrusion 431c is adapted to be engaged in the limiting groove on the mating surface of the hair dryer, so as to ensure that the accessory can be better connected and fixed to the hair dryer.

[0131] In one embodiment, the locking structure 100c further includes a driving component 5c connected to the second seat 3c. The driving component 5c is used to drive the second seat 3c to rotate, so that the second locking part 32c on the second seat 3c can be adapted to engage or disengage with the second mating part on the main body of the device, so that the second seat 3c can rotate independently, thereby avoiding the twisting and damage of the insertion pin 22c.

[0132] It is understood that, in one embodiment, the driving component 5c may be configured as a driver to drive the second seat 3c to rotate.

[0133] Preferably, the drive component 5c is moved by manual rotation so that the second seat 3c can move together. Specifically, as shown in Figures 20 and 21, the drive component 5c includes a toggle button 51c and an elastic reset member connecting the toggle button 51c and the first seat 1c. At least a portion of the toggle button 51c is exposed outside the first seat 1c and has a circumferential travel along the second seat 3c under external force. Rotation of the toggle button 51c drives the second seat 3c to rotate together. The structure is simpler and the disassembly of accessories is more convenient.

[0134] The first seat 1c and the adjusting ring 41c are provided with corresponding elongated holes, which extend circumferentially along the second seat 3c. A toggle button 51c passes through the two elongated holes and extends out of the first seat 1c for easy operation by the user. The length of the elongated holes also limits the rotation of the second seat 3c. When the second seat 3c rotates to the point where it can disengage from the hair dryer, it engages fully with the adjusting ring 41c. When the second seat 3c is reset by the elastic reset member to engage with the hair dryer, the first locking part 31c and the first mating part 23c are also in an engaged position.

[0135] Preferably, the toggle button 51c is detachably connected to the second base 3c to facilitate the assembly of the second base 3c.

[0136] Preferably, as shown in FIG21, the first locking part 31c includes a first notch 311c provided at the first end of the second base 3c, the second locking part 32c includes a second notch 321c provided at the second end of the second base 3c, and the first mating part 23c includes a snap-fit ​​boss 231c provided inside the connecting ring 21c. The notch of the first notch 311c and the notch of the second notch 321c are staggered in the vertical direction, and the rotation assembly operation is more convenient and simple.

[0137] This application also provides an accessory including the aforementioned locking structure 100c. The locking structure 100c makes it easier to connect or disconnect the accessory from the hair dryer. Moreover, the accessory can better ensure that the electrical connection component 2c will not rotate during disassembly or installation. Therefore, it can better protect the electrical connection component 2c while making disassembly and installation convenient.

[0138] Example 4

[0139] Referring to Figures 22 to 27, this application specifically provides a hair dryer 100d. It should be noted that the hair dryer 100d in this specific embodiment 4 can be the hair dryer in specific embodiment 1 described above, or it can be another hair dryer different from that in specific embodiment 1 described above. Similarly, one or more embodiments in this specific embodiment 4 can be combined with one or more embodiments in specific embodiments 2 and 3 described above, and should also have the effects possessed by the above embodiments, which will not be elaborated further.

[0140] Specifically, referring to Figures 22 and 23, in this embodiment, the hair dryer 100d includes a blower body 1d, a docking structure 2d, and a locking structure 3d. The blower body 1d has an air outlet 111d. The docking structure 2d is disposed within the air outlet 111d and includes a first limiting part 23d and a second limiting part 24d. The first limiting part 23d is adapted to be positioned and engaged with the first mating part 64d on the accessory 200d to form a stop fit along the circumference of the air outlet 111d. The second limiting part 24d is adapted to drive the rotating cylinder 62d, where the second mating part 65d is located on the accessory 200d, to rotate in a first direction to form a stop fit with the second mating part 65d along the axial direction of the air outlet 111d. The locking structure 3d is disposed on the blower body 1d and has a locked state and an unlocked state. When the second limiting part 24d is adapted to engage with the second mating part 65d, the locking structure 3d automatically switches from the locked state to the unlocked state and is adapted to restrict the rotating cylinder 62d from rotating in the opposite direction to the first direction.

[0141] In this embodiment, the airflow generated by the blower body 1d can be blown out from the air outlet 111d; it is connected to the accessory 200d via the docking structure 2d. During connection, the first limiting part 23d can be positioned and engaged with the first mating part 64d on the accessory 200d, thereby restricting the accessory 200d to the blower 100d in the circumferential direction. Furthermore, the second limiting part 24d can be engaged with the second mating part 65d on the accessory 200d to stop it, thereby restricting the accessory 200d to the blower 100d in the axial direction of the air inlet. This ensures that the accessory 200d is restricted to the blower 100d both axially and circumferentially, making it easier to assemble and disassemble the accessory 200d from the blower 100d and facilitating replacement. Furthermore, when the accessory 200d is installed, once the first mating part and the second mating part are reliably connected, the second limiting part 24d can drive the second mating part 65d to rotate and engage, and the locking structure 3d can lock the second mating part 65d in place, thereby keeping the accessory 200d fixed on the blower 100d and ensuring that the accessory 200d works more stably when installed on the blower 100d.

[0142] The blower body 1d includes a blower assembly 11d and a handle assembly 12d, with an air outlet 111d formed on the blower assembly 11d. Preferably, both the blower assembly 11d and the handle assembly 12d are generally cylindrical. The air outlet 111d is formed at the axial end of the blower assembly 11d.

[0143] In one embodiment, as shown in Figures 21 and 23, the docking structure 2d includes a docking ring 21d and a first guide portion 22d disposed on the docking ring 21d. The first guide portion 22d is disposed facing outward from the air outlet 111d and is adapted to be electrically connected to a second guide portion 63d on the accessory 200d. Through the first guide portion 22d, the accessory 200d can be electrically connected to the second guide portion 63d on the accessory 200d, so that after the accessory 200d is installed on the blower 100d, the accessory 200d can be controlled to operate by the blower 100d. The docking ring 21d is sleeved inside the air outlet 111d and is adapted to the shape of the air outlet 111d. Preferably, the docking ring 21d is approximately circular. The mating ring 21d is fixed to the inner side of the air duct assembly 11d. The mating ring 21d can be connected and fixed through a snap-fit ​​structure and / or a screw-fit structure, so that the mating ring 21d can be stably fixed to the inner side of the air duct assembly 11d, making the accessory 200d more stable and less prone to shaking when installed on the air duct assembly 11d. The first guide part 22d and the first limiting part 23d are provided on the ring end face of the mating ring 21d, and the second limiting part 24d is provided on the inner ring side of the mating ring 21d. This allows the accessory 200d to be inserted and fitted along the axial direction of the air outlet 111d, thereby allowing the first guide part 22d and the first limiting part 23d to better mate and fit with the second guide part 63d and the first mating part 64d on the accessory 200d. The locking and unlocking of the second limiting part 24d and the second mating part 65d are controlled by the locking structure 3d. Moreover, during locking and unlocking, the rotating cylinder 62d on the accessory 200d is driven to rotate by the second limiting part 24d to engage or unlock. There will be no relative frictional movement between the first guide part 22d and the second guide part 63d, which can better avoid frictional damage to the first guide part 22d and the second guide part 63d and better ensure the reliability of the connection between the first guide part 22d and the second guide part 63d.

[0144] It is understandable that the connection method of the first conductive part 22d and the second conductive part 63d will differ depending on the connection method. The first conductive part 22d and the second conductive part 63d can be connected by contact, plug-in, or electromagnetic connection. A circuit board electrically connected to the second conductive part 63d can be provided in the accessory 200d, and a circuit structure electrically connected to the first conductive part 22d is also provided in the blower 100d.

[0145] For example, the first guide portion 22d can be configured as multiple first contacts, and the second guide portion 63d can be configured as multiple second contacts. When the first contacts and the second contacts are in contact, the blower 100d and the accessory 200d are electrically connected, and electrical energy and / or electrical signals can be provided to the accessory 200d through the blower 100d, so that the accessory 200d can work under the control of the blower 100d. Alternatively, when the first guide portion 22d and the second guide portion 63d are in contact, the blower 100d can automatically identify the information of the accessory 200d (such as accessory type, model, etc.), and the blower 100d can better control the operation of the accessory 200d based on the identified accessory 200d information. Preferably, as shown in FIG23, the first guide portion 22d includes multiple docking holes 221d provided on the docking ring 21d. Each docking hole 221d is arranged through the docking ring 21d along the axial direction of the docking ring 21d, and the multiple docking holes 221d are arranged at intervals along the circumferential direction of the docking ring 21d. Multiple docking posts can be provided in the docking hole 221d, and at least a portion of the second conductive part 63d extends into each docking hole 221d, so that the second conductive part 63d can be better electrically connected to the first conductive part 22d.

[0146] The first limiting part 23d includes a limiting groove 231d provided on the docking ring 21d, with the opening of the limiting groove 231d facing outwards from the air outlet 111d. The limiting groove 231d engages with the limiting protrusion 651d on the accessory 200d, preventing the accessory 200d from rotating relative to the air duct assembly 11d. Since the docking holes 221d are located at the axial end of the docking ring 21d, to ensure better strength of the ring wall, the radial wall thickness of the docking ring 21d in the area containing the multiple docking holes 221d is obviously greater. This results in the inner ring side of the docking ring 21d being eccentrically positioned to accommodate the multiple docking holes 221d. The multiple docking holes 221d are symmetrically arranged on both sides of the limiting groove 231d, making the overall arrangement of the docking ring 21d more uniform.

[0147] Preferably, as shown in Figures 23 and 24, the second limiting portion 24d includes an inlet 241d and a first limiting surface 242d disposed on one side of the inlet 241d along the circumferential direction of the mating ring 21d. When the accessory 200d is subjected to external force, i.e., when the user manually installs the accessory 200d onto the blower 100d, the second mating portion 65d is adapted to extend into the inlet 241d under manual operation. As the second mating portion 65d continues to be inserted into the inlet 241d, the first limiting surface 242d is adapted to form a wedge-shaped engagement with the second mating portion 65d, causing the second mating portion 65d to rotate in a first direction and engage at the limiting surface. The locking structure 3d is adapted to abut against the side of the second mating portion 65d opposite to the first limiting surface 242d. The second mating part 65d on the accessory 200d is inserted into the inlet 241d. As the accessory 200d is continuously inserted, the wedge-shaped engagement of the first limiting surface 242d and the second mating part 65d converts the axial displacement of the accessory 200d into a circumferential displacement, causing the rotating cylinder 62d containing the second mating part 65d to rotate. This results in the projection of the second mating part 65d onto the orthographic projection along the axial direction of the air outlet 111d, where the projection of the second mating part 65d at least partially overlaps with the projection of the first limiting surface 242d. Furthermore, relative to the outer end face of the air outlet 111d, the second mating part 65d is located inside the first limiting surface 242d. Therefore, along the axial direction of the air outlet 111d, the second mating part 65d engages with the first limiting surface 242d to prevent the accessory 200d from dislodging from the air duct assembly 11d. Furthermore, the second mating part 65d is abutted against the side of the first limiting surface 242d by the locking structure 3d, so that the second mating part 65d will not rotate in the opposite direction and will disengage from the first limiting surface 242d, ensuring that the accessory 200d is locked stably and reliably on the blower 100d.

[0148] The aforementioned second limiting part 24d can be provided in multiples, and the multiple second limiting parts 24d are arranged at intervals along the circumference of the air outlet 111d. By having multiple second limiting parts 24d and multiple second mating parts 65d cooperate one-to-one, the arrangement of the connection between the blower 100d and the accessory 200d along the axial direction of the air outlet 111d is more uniform, and the force on the accessory 200d is more uniform, so it is not easy for it to shake relative to the blower 100d.

[0149] The aforementioned locking structure 3d can be configured as a telescopic locking member. The locking member extends to abut against the second mating part 65d, thereby locking the accessory 200d onto the hair dryer 100d. By retracting the locking member to avoid the second mating part 65d, the accessory 200d is unlocked, allowing it to be removed from the hair dryer 100d.

[0150] Preferably, as shown in FIG23, the locking structure 3d includes a locking plate 31d and an elastic telescopic member 32d connecting the locking plate 31d and the blower body 1d. When in the locked state, the elastic telescopic member 32d is in a naturally extended state, and at least a portion of the locking plate 31d can extend into the inside of the mating ring 21d to abut against the side of the second mating part 65d opposite to the first limiting surface 242d. Thus, along the circumference of the mating ring 21d, the first limiting surface 242d and the locking plate 31d abut against the two sides of the second mating part 65d respectively, thereby completely locking the second mating part 65d in the circumferential direction.

[0151] As shown in Figures 22 and 23, the locking plate 31d has an adjusting part 33d, which is exposed on the peripheral side of the blower body 1d. Under external force, the adjusting part 33d can switch between a locked and unlocked state. When the user installs the accessory 200d onto the blower 100d, the accessory 200d can be directly connected to the air inlet of the blower 100d, so that the first guide part 22d and the second guide part 63d are inserted into each other, and the first limiting part 23d is connected to the first mating part 64d. At this time, under the insertion force of the accessory 200d, the rotating cylinder 62d can be automatically driven to rotate through the second limiting part 24d, and the accessory 200d can abut against the locking plate 31d, so that the locking plate 31d is in the retracted position. When the rotating cylinder 62d rotates a certain angle, causing the second limiting part 24d and the second mating part 65d to fully engage, the locking plate 31d extends under the elastic restoring force of the elastic telescopic member 32d to abut against the second mating part 65d, thereby locking the accessory 200d onto the blower 100d. Installation is simple and convenient. When it is necessary to disassemble the accessory 200d, the user can operate the adjusting part 33d to move it away from the air outlet 111d. This causes the locking plate 31d to move together and separate from the second mating part 65d. The second mating part 65d can then rotate in the opposite direction to exit the first limiting surface 242d formed by the second limiting part 24d. The second limiting part 24d and the second mating part 65d no longer form a stop-fit ​​along the axial direction of the air outlet 111d, allowing the accessory 200d to be removed from the blower 100d.

[0152] An elastic reset member (not shown in the drawings) may be provided between the rotating cylinder 62d of the attachment 200d and the attachment body 5d. When the second mating part 65d is engaged with the second limiting part 24d and the locking plate 31d abuts against the second mating part 65d, the elastic reset member is in an elastic energy storage state. When the locking plate 31d no longer abuts against the second mating part 65d, under the action of the elastic restoring force of the elastic reset member, the rotating cylinder 62d can be driven to rotate in the opposite direction to the first direction, so that the second mating part 65d can be rotated out of the first limiting surface 242d, and the attachment 200d can move axially relative to the blower 100d along the air outlet 111d to be taken out from the blower 100d.

[0153] Furthermore, the hair dryer 100d also includes a pivot structure 4d; the pivot structure 4d pivotally connects the blower assembly 11d and the handle assembly 12d, allowing the blower assembly 11d and the handle assembly 12d to rotate relative to each other, to have an extended state and a bent state. In the extended state, the blower assembly 11d and the handle assembly 12d are arranged in a straight line, and the rotation center of the pivot structure 4d is offset on the same side of the central axis of the blower assembly 11d and the central axis of the handle assembly 12d.

[0154] The hair dryer 100d can be configured as a hair dryer. An air outlet 111d is provided on the air duct assembly 11d.

[0155] It is understood that the hair dryer 100d may also include a heating element and a circuit structure. The heating element is electrically connected to the circuit structure, which controls its operation. The heating element and the circuit structure may both be housed within the hair dryer assembly 11d, or they may be housed separately within the hair dryer assembly 11d and the handle assembly 12d. The circuit structure may include a controller. After the first conductive part 22d and the second conductive part 63d are connected, the controller can identify information from the accessory 200d, thereby better controlling the operation of the accessory 200d.

[0156] Preferably, the heating element is located within the air duct assembly 11d, the circuit structure is located within the handle assembly 12d, the air inlet is located on the handle assembly 12d, and a ventilation channel is provided on the pivot structure 4d, connecting the air inlet and the air outlet 111d, thus connecting the air duct assembly 11d and the handle assembly 12d. Along the airflow direction, the circuit structure is located within the connecting channel between the air inlet and the ventilation channel, allowing cold airflow to enter the handle assembly 12d from the air inlet, flow through the circuit structure, then through the ventilation channel into the air duct assembly 11d, and after being heated by the heating structure, flow out of the air duct assembly 11d from the air outlet 111d. This arrangement allows cold airflow to flow through the circuit structure for heat dissipation, and also allows hot airflow from the periphery of the circuit structure to be drawn into the air duct assembly 11d, improving heating efficiency and saving heating energy.

[0157] Preferably, during the relative rotation of the air duct assembly 11d and the handle assembly 12d, the central axis of the air duct assembly 11d and the central axis of the handle assembly 12d are always located on the same plane.

[0158] Preferably, as shown in Figure 22, when in the extended state, the air duct assembly 11d and the handle assembly 12d are coaxially arranged. Specifically, the air duct assembly 11d has a first connecting end and a first free end facing each other along its axial direction, and the handle assembly 12d has a second connecting end and a second free end facing each other along its axial direction. In the extended state, the first connecting end of the air duct assembly 11d and the second connecting end of the handle assembly 12d are connected to each other, the first free end of the air duct assembly 11d is oriented towards the direction away from the handle assembly 12d, and the second free end of the handle assembly 12d is oriented towards the direction away from the air duct assembly 11d. At this time, the air duct assembly 11d and the handle assembly 12d are fully extended, the air resistance in the airflow path is smaller, and therefore the air outlet efficiency is higher. It can be understood that when in the extended state, the included angle between the two can approach 180º, such as 180º±5º, so that the air duct assembly 11d and the handle assembly 12d are roughly arranged in a straight line.

[0159] When the air duct assembly 11d and the handle assembly 12d are in a bent state, the air duct assembly 11d and the handle assembly 12d are roughly in a "V" shape or an "L" shape.

[0160] If the air duct assembly 11d and the handle assembly 12d are set to rotate on a horizontal plane, then preferably, the pivot axis of the pivot structure 4d is set in the vertical direction. When in the extended state, the pivot axis of the pivot structure 4d is perpendicular to the central axis of the air duct assembly 11d and / or the central axis of the handle assembly 12d, so that the air duct assembly 11d and the handle assembly 12d rotate more smoothly and are not easy to twist or shake.

[0161] This application also provides an accessory 200d, which is suitable for use with the aforementioned hair dryer 100d. Specifically, as shown in FIG25, the accessory 200d includes an accessory body 5d and a mating structure 6d. The accessory body 5d is hollow and its first axial end is open. The mating structure 6d is located at the first end of the accessory body 5d. The mating structure 6d includes a first mating part 64d and a second mating part 65d. The first end of the accessory body 5d is adapted to extend into the air inlet of the hair dryer 100d, such that the first mating part 64d is adapted to form a stop fit with the first limiting part 23d along the circumference of the accessory body 5d, and the second mating part 65d is adapted to form a stop fit with the second limiting part 24d of the hair dryer 100d along the axial direction of the accessory body 5d, so that the accessory 200d can be better attached to and detached from the hair dryer 100d.

[0162] The accessory body 5d is roughly cylindrical, with its first end connected to the hair dryer 100d. The air outlet 111d of the hair dryer 100d is connected to the first end of the accessory body 5d, allowing the airflow generated by the hair dryer 100d to better enter the accessory body 5d and be blown towards the user for use.

[0163] Specifically, referring to Figures 25 and 27, the mating structure 6d includes a second guide portion 63d, a connector 61d located at the first end of the accessory body 5d, and a rotating cylinder 62d rotatably mounted on the connector 61d. The second guide portion 63d is adapted to be electrically connected to the first guide portion 22d. The connector 61d is generally cylindrical, and the rotating cylinder 62d is rotatably located inside the connector 61d. When the accessory 200d is installed on the blower 100d, preferably, the outer diameter of the connector 61d is the same as the outer diameter of the blower assembly 11d, so that the accessory 200d and the blower assembly 11d have better compatibility.

[0164] Furthermore, at least a portion of the rotating cylinder 62d extends beyond the connector 61d, allowing the connector 61d to better extend into the air outlet 111d when the accessory 200d is aligned with the blower 100d. The second guide portion 63d and the first mating portion 64d are located on the end face of the connector 61d, and the second mating portion 65d is located on the outer peripheral side of the rotating cylinder 62d. Therefore, the second guide portion 63d, the first guide portion 22d, the first limiting portion 23d, the first mating portion 64d, the second limiting portion 24d, and the second mating portion 65d can all better align and engage.

[0165] Furthermore, as shown in FIG25, the second guide part 63d includes a plurality of mating plugs 631d disposed on the connector 61d. The plurality of mating plugs 631d are arranged at intervals along the circumference of the rotating cylinder 62d to be suitable for one-to-one insertion and engagement with the plurality of mating holes 221d of the hair dryer 100d, thereby guiding and connecting the accessory 200d and the hair dryer 100d.

[0166] The first mating part 64d includes a limiting protrusion 641d protruding from the end face of the connector 61d. The limiting protrusion 641d is adapted to be positioned and engaged with the limiting groove 231d of the hair dryer 100d to restrict the rotation of the accessory 200d relative to the hair dryer 100d, thereby limiting the accessory 200d and the hair dryer 100d in the circumferential direction.

[0167] The second mating part 65d includes a limiting protrusion 651d provided on the outer periphery of the rotating cylinder 62d. The limiting protrusion 651d has a second limiting surface that wedges with the first limiting surface 242d of the blower 100d. When the accessory 200d is inserted into the air outlet 111d along the axial direction of the air outlet 111d, the second limiting surface gradually wedges with the first limiting surface 242d, thereby driving the second mating part 65d to rotate relative to the second limiting part 24d. This causes the overlap area between the second limiting surface and the first limiting surface 242d to gradually increase along the axial direction of the air outlet 111d, forming a stop fit in the axial direction, restricting the movement of the accessory 200d relative to the blower 100d along the axial direction of the air outlet 111d.

[0168] Furthermore, multiple limit protrusions 651d are provided, and multiple limit protrusions 651d and multiple second limit parts 24d are configured in a one-to-one correspondence. The accessory 200d and the blower 100d form multiple stop fits in the axial direction, which further ensures the stability of the accessory 200d during installation.

[0169] This application also provides a styling device 1000d, as shown in Figures 26 and 27. The styling device 1000d includes the aforementioned hair dryer 100d and the aforementioned accessory 200d. The accessory 200d can be easily detached from the hair dryer 100d, making it easier to replace and simplifying operation. Furthermore, the detachment and reassembly of the accessory 200d will not cause wear or other damage to the electrical connection between the accessory 200d and the hair dryer 100d, thus better ensuring the reliability of the electrical connection between the accessory 200d and the hair dryer 100d and extending the service life of the entire styling device 1000d.

[0170] Example 5

[0171] Referring to Figures 28 to 36, this application specifically provides an accessory 100f and a molding device. It should be noted that the accessory 100f and molding device in this specific embodiment 6 can be the accessory and molding device in the above-described specific embodiment 1, or it can be other accessories and molding devices different from those in the above-described specific embodiment 1. Similarly, one or more embodiments of this specific embodiment 6 can be combined with one or more embodiments of the above-described specific embodiments 2 to 5, and should also have the effects possessed by the above embodiments, which will not be elaborated further.

[0172] The accessory 100f is applicable to molding equipment and is suitable for use with the main body of the blower. Specifically, please refer to Figures 28 and 29. In this embodiment, the accessory 100f includes a connecting structure 1f and an air outlet 2f. The connecting structure 1f has a first end and a second end arranged opposite to each other. The first end of the connecting structure 1f is adapted to be detachably connected to the main body of the blower. The air outlet 2f is rotatably disposed at the second end of the connecting structure 1f. The air outlet 2f is provided with an air outlet 2111f, which is adapted to be connected to the main body of the blower through the connecting structure 1f. The air outlet 2111f is elongated. By rotating the air outlet 2f relative to the connecting structure 1f, the angle between the length direction of the air outlet 2111f and the rotation axis of the air outlet 2f is adjustable.

[0173] In this embodiment, the first end of the connecting structure 1f is detachably connected to the fan body, making it easy to detach and install the entire accessory 100f from the fan body, facilitating the replacement of different types of accessories 100f. The air outlet 2f is rotatably mounted at the second end of the connecting structure 1f, and an air outlet 2111f is provided on the air outlet 2f, which is connected to the fan body via the connecting structure 1f. The airflow generated inside the fan body can enter the connecting structure 1f, flowing towards the air outlet 2111f and being blown out from the air outlet 2111f for user use. Furthermore, the air outlet 2111f is designed to be long and narrow, and its flat shape makes the airflow more concentrated and faster. The airflow can be blown out in a roughly straight line, with a more directional airflow. Therefore, when blowing onto the user's hair, the hair is less likely to become tangled and can be better combed in one direction. Furthermore, the air outlet 2f can rotate relative to the connecting structure 1f, so that the angle between the length direction of the air outlet 2111f and the rotation axis of the air outlet 2f can be adjusted, that is, the air outlet direction of the air outlet 2111f can be adjusted. Thus, when the user is styling their hair, they can directly change the air outlet direction by driving the air outlet 2f to rotate, without the need for the user to move their hands to adjust the direction. Obviously, the operation is more convenient and less strenuous.

[0174] It is understandable that the rotation of the air outlet 2f can be driven by a drive device, allowing the air outlet 2f to rotate relative to the connecting structure 1f. Driving the air outlet 2f to rotate by a drive device allows for more precise angle adjustment and more intelligent operation. Alternatively, the air outlet 2f can be manually driven, making the structure of accessory 100f simpler and lower in cost.

[0175] Preferably, the air outlet 2f is rotatably sleeved on one end of the connecting structure 1f, allowing it to rotate relative to the connecting structure 1f by manual rotation. Specifically, referring to Figures 29 and 31, the air outlet 2f includes an air outlet component 21f and a housing component 22f. The air outlet component 21f is hollow with openings at both ends. One end of the air outlet component 21f is rotatably connected to the connecting structure 1f, and the air outlet 2111f is located at the other end of the air outlet component 21f. The airflow blown from the fan body can enter the connecting structure 1f and then enter the air outlet component 21f. The housing component 22f is connected to the air outlet component 21f and surrounds the outer periphery of the air outlet component 21f. One end of the housing component 22f is rotatably sleeved between the connecting structure 1f and the air outlet component 21f, and the other end of the housing component 22f has a through hole whose shape matches the shape of the air outlet 2111f. By stacking the outer shell 22f and the air outlet 21f in two layers, the strength of the air outlet 2f can be increased, while the outer shell 22f can also provide heat insulation, preventing the air outlet 21f from getting too hot and burning the user.

[0176] Furthermore, preferably, the shape of the outer shell 22f matches the shape of the air outlet 21f, so that the outer shell 22f can fit better into the air outlet 21f, and the air outlet 2f has a more compact structure, thus making it smaller in size.

[0177] In particular, the connection methods of the air outlet 2f and the connecting structure 1f are slightly different, depending on the specific structure of the outer shell 11 and the air outlet 21f.

[0178] In one embodiment, as shown in FIG31, the air outlet 21f has a first central cylindrical portion 211f and two first wing portions 212f located on both sides of the first central cylindrical portion 211f. The two first wing portions 212f are symmetrically arranged on both radial sides of the first central cylindrical portion 211f. The first central cylindrical portion 211f and the two first wing portions 212f are hollow, and a through hole is provided at the connection between the first central cylindrical portion 211f and the two first wing portions 212f, so that the first central cylindrical portion 211f and the two first wing portions 212f are connected. The first central cylindrical portion 211f and the two first wing portions 212f are both open at the end away from the connecting structure 1f to form an air outlet 2111f. On the one hand, while making the overall volume of the air outlet 2f smaller, the length of the air outlet 2111f can be longer; on the other hand, it is more convenient for users to drive the air outlet 2f to rotate by operating the first wing-shaped part 212f, making the rotation operation more convenient.

[0179] The shape of the outer casing 22f matches the shape of the air outlet 21f. The outer casing has a second central cylindrical portion and two second wing-shaped portions located on both sides of the second central cylindrical portion, which are symmetrically arranged on both radial sides of the second central cylindrical portion. The second central cylindrical portion is fitted onto the outside of the first central cylindrical portion 211f, and the two second wing-shaped portions respectively cover the outside of the two first wing-shaped portions 212f.

[0180] Specifically, as shown in Figure 31, the outer casing 22f includes a first casing 221f and a second casing 222f that are connected to each other. The first casing 221f and the second casing 222f are respectively sandwiched on both sides of the air outlet 21f and are arranged symmetrically. The first casing 221f and the second casing 222f together enclose the aforementioned second central cylindrical portion and two second wing-shaped portions.

[0181] One of the first housing 221f and the second housing 222f is provided with a second hook 2121f, and the other is provided with a second fastener 223f that engages with the second hook 2121f. The second hook 2121f and the second fastener 223f engage to connect the first housing 221f and the second housing 222f and clamp the air outlet 21f therein. Alternatively, one of the first housing 221f and the air outlet 21f is provided with a second hook 2121f, and the other is provided with a second fastener 223f that engages with the second hook 2121f. The second hook 2121f and the second fastener 223f engage to connect the first housing 221f and the air outlet 21f. And / or, one of the second housing 222f and the air outlet 21f is provided with a second hook 2121f, and the other is provided with a second buckle 223f that engages with the second hook 2121f. The second hook 2121f and the second buckle 223f engage to connect the second housing 222f and the air outlet 21f. The first housing 221f and the second housing 222f are connected by ultrasonic welding. When assembling the air outlet 2f, the first housing 221f or the second housing 222f can be first engaged with the air outlet 21f, and then the second housing 222f or the first housing 221f can be placed on the outside of the air outlet 21f. Then, the first housing 221f and the second housing 222f are connected and fixed by ultrasonic welding to ensure the reliability of the connection between the first housing 221f and the second housing 222f.

[0182] Multiple second hooks 2121f can be provided, and these hooks 2121f are located on the outer sides of the two first wing-shaped portions 212f of the air outlet 21f, respectively, on both sides of each first wing-shaped portion 212f facing the first housing 221f and the second housing 222f. The multiple second hooks 2121f are positioned near the end of the air outlet 2111f. Multiple second fasteners 223f are provided on the inner sides of both the first housing 221f and the second housing 222f to engage with the multiple second hooks 2121f. This ensures a tighter connection between the first housing 221f and the second housing 222f and the air outlet 21f, preventing the air outlet 2111f from cracking and avoiding accidental hair trapping.

[0183] The air outlet 2f is connected to the connecting structure 1f and is not easily detached, while it can rotate relative to the connecting structure 1f. Specifically, the connecting structure 1f is generally cylindrical with openings at both ends. The end of the air outlet 2f facing away from the air outlet 2111f is rotatably fitted inside the opening at the second end of the connecting structure 1f. Further, a first connecting part 2112f is provided inside the air outlet component 21f, and a second connecting part 124f is provided on the connecting structure 1f. At least a portion of the second connecting part 124f extends into the air outlet component 21f to cooperate with the first connecting part 2112f, allowing the air outlet component 21f to rotate relative to the connecting structure 1f. Through the cooperation of the first connecting part 2112f and the second connecting part 124f, the air outlet 2f is prevented from detaching from the connecting structure 1f while ensuring its rotation.

[0184] Specifically, as shown in FIG30, the first connecting portion 2112f is disposed inside the first central cylindrical portion 211f, and the first connecting portion 2112f includes a first mounting hole 2112a disposed inside the first central cylindrical portion 211f. The second connecting portion 124f includes a second mounting hole 1241f protruding from the second end of the connecting structure 1f. At least a portion of the second mounting hole 1241f is inserted into the first mounting hole 2112a, such that one end of the first mounting hole 2112a abuts against the outer side of the second mounting hole 1241f, and the end face of the second mounting hole 1241f can protrude from the other end of the first mounting hole 2112a. Annex 100f also includes a connector that passes through the second mounting hole 1241f and presses against the end face of the second mounting hole 1241f that protrudes from the first mounting hole 2112a, thereby confining the air outlet 21f to the connecting structure 1f and allowing the first mounting hole 2112a to rotate relative to the second mounting hole 1241f. The second mounting hole 1241f and the connector limit the air outlet 21f along the axial direction of the connecting structure 1f, thus preventing the air outlet 21f from detaching from the connecting structure 1f. Furthermore, because the connector presses against the end face of the second mounting hole 1241f but not completely against the first mounting hole 2112a, the first mounting hole 2112a can rotate relative to the second mounting hole 1241f, thereby allowing the air outlet 2f to rotate relative to the connecting structure 1f.

[0185] The second mounting hole 1241f has a protruding support portion on its outer periphery. One end of the first mounting hole 2112a is pressed against the support portion, and the other end of the first mounting hole 2112a is limited by a connector. The end face of the second mounting hole 1241f is slightly protruding from the end face of the first mounting hole 2112a facing the air outlet 2111f. This prevents the connector from being directly pressed against the first mounting hole 2112a, and allows the connector to limit the first mounting hole 2112a in its axial direction. This ensures a reliable connection between the air outlet 2f and the connecting structure 1f, while also allowing the air outlet 2f to rotate relative to the connecting structure 1f. The connector can be a screw or bolt, etc. When assembling the air outlet 2f and the connecting structure 1f, one end of the air outlet 2f can be fitted into the second end of the connecting structure 1f so that the first mounting hole 2112a can abut against the support. Then, the connector can be inserted from the top opening of the first central cylindrical part 211f and screwed into the second mounting hole 1241f, thus completing the assembly. The assembly method is simpler and more convenient.

[0186] In another embodiment, as shown in Figures 32 and 33, the air outlet 21f21 has an air outlet body 213f and an air outlet head 214f ​​located at the end of the air outlet body 213f. One end of the air outlet body 213f is connected to the connecting structure 1f, and the air outlet head 214f ​​is located at the other end of the air outlet body 213f. The air outlet 2111f is located at the end of the air outlet body 213f facing away from the connecting structure 1f and is roughly in the shape of an "I", making the air outlet cross-section of the air outlet 2111f more uniform, thereby making the air outlet more uniform. The shapes of the first housing 221f and the second housing 222f match the shape of the air outlet 21f to cover the outside of the air outlet 21f.

[0187] Further, referring to Figures 34 to 36, one end of the connecting structure 1f is fitted inside the air outlet 21f. The first connecting portion 2112f includes a first hook 2112b disposed on the inner ring side of the air outlet 21f. The second connecting portion 124f includes a first fastening portion 1242f disposed on the outer ring side of the connecting structure 1f. The end of the first hook 2112b abuts against the connecting structure 1f and engages with the first fastening portion 1242f, allowing the first hook 2112b to rotate circumferentially relative to the first fastening portion 1242f relative to the first fastening portion 1242f. By abutting against the connecting structure 1f with the end of the first hook 2112b, the movement of the air outlet 21f toward the connecting structure 1f is restricted in the axial direction along the connecting structure 1f. The first hook 2112b engages with the first fastener 1242f to restrict the movement of the air outlet 21f away from the connecting structure 1f, thus restricting the air outlet 21f to the connecting structure 1f axially. However, the air outlet 21f can also rotate relative to the connecting structure 1f circumferentially, thereby allowing the air nozzle to rotate to adjust the air outlet 2111f's airflow direction.

[0188] The first hook 2112b can be arranged in a ring shape at the end of the air outlet body 213f. Alternatively, the first hook 2112b can be segmented, including multiple sub-hooks. The multiple sub-hooks are spaced apart circumferentially along the air outlet body 213f, making each sub-hook easily elastically deformable, thus facilitating engagement when fastened to the first buckle 1242f. The first buckle 1242f can be arranged in a complete ring shape to ensure better engagement strength.

[0189] In terms of the specific structure of the connection structure 1f, the connection structure 1f includes a connection ring 11f, a support ring 12f, a circuit structure 13f, a locking cylinder 14f, and a telescopic ring 15f.

[0190] The connecting ring 11f is roughly cylindrical, and its outer diameter matches the outer diameter of the interface of the wind turbine body. This ensures better mating of the accessory 100f with the wind turbine body when it is installed, resulting in a smoother transition at the connection point.

[0191] A support ring 12f is fixedly sleeved on the inner side of the connecting ring 11f. A second connecting part 124f is located at one end of the support ring 12f and extends from the end of the connecting ring 11f. The support ring 12f is connected to the first connecting part 2112f on the inner side of the air outlet 21f through the second connecting part 124f, thereby restricting the air outlet 21f to the support ring 12f to ensure the position of the air outlet 21f and the entire air outlet 2f relative to the support ring 12f.

[0192] In one embodiment, as shown in Figures 30 and 31, the support ring 12f includes a ring body 121f, multiple support arms 122f, and a support post 123f. The ring body 121f is fixedly sleeved on the inner side of the connecting ring 11f and is located near the second end of the connecting ring 11f. The multiple support arms 122f are spaced apart circumferentially along the ring body 121f, and one end is connected to the ring body 121f. The multiple support arms 122f protrude from the connecting ring 11f and extend into the air outlet 21f. The support post 123f is located at the other end of the multiple support arms 122f, and a second mounting hole 1241f is provided on the support post 123f. Multiple support arms 122f support the support column 123f on the inner side of the air outlet 21f, so that the second mounting hole 1241f can be inserted into the first mounting hole 2112a, thereby ensuring that the first mounting hole 2112a and the second mounting hole 1241f are accurately aligned.

[0193] Preferably, the connecting ring 11f, support ring 12f, locking cylinder 14f, and telescopic ring 15f are all coaxially arranged. They are also coaxially arranged with the second mounting hole 1241f, so that the connection between the connecting structure 1f and the air outlet 21f is located in the middle of the air outlet 2f. When the air outlet 2f rotates, it can rotate more effectively around the central axis of the connecting structure 1f, resulting in more stable rotation.

[0194] In another embodiment, the first buckle 1242f is provided on the outer periphery of the end of the support ring 12f, and when the support ring 12f is sleeved on the inner side of the air outlet 21f, it can be engaged with the first hook 2112b of the air outlet 21f.

[0195] A circuit structure 13f is located at the other end of the support ring 12f and includes multiple connectors 131f. The circuit structure 13f may also include a circuit board, to which the connectors 131f are electrically connected. The connectors 131f are adapted to mate with mating parts on the fan body to electrically conduct electricity between the fan body and the accessory 100f, allowing the fan body to identify the type of accessory 100f and thus control the operation of accessory 100f or control the velocity and / or flow rate of the airflow entering accessory 100f. The circuit board is also generally annular, allowing airflow to pass through its center, ensuring that airflow can pass through the connecting structure 1f to the outlet nozzle 2f.

[0196] The locking sleeve 14f is rotatably sleeved inside the support ring 12f and is suitable for docking and communicating with the fan body. One end of the air outlet 2f is rotatably sleeved between the connecting ring 11f and the locking sleeve 14f. The locking sleeve 14f can be locked or unlocked with the fan body by rotation. This makes it easier to assemble and disassemble the connecting structure 1f when it is docked with the fan body.

[0197] The telescopic ring 15f is movably sleeved between the connecting ring 11f and the locking cylinder 14f. The telescopic ring 15f has multiple through holes for the multiple connectors 131f to pass through in a one-to-one correspondence. The telescopic ring 15f has a travel along the axial direction of the locking cylinder 14f, allowing it to have a first working state in which the multiple connectors 131f retract into the multiple through holes, and a second working state in which the multiple connectors 131f can extend out from the multiple through holes. After the accessory 100f is removed from the fan body, the telescopic ring 15f allows the multiple connectors 131f to retract within it, protecting them from damage or bending that could affect the electrical connection performance between the accessory 100f and the fan body. When the accessory 100f is connected to the main body of the wind turbine, the movement of the telescopic ring 15f allows multiple plug-in parts 131f to be better exposed so as to connect and conduct electricity with the docking parts on the main body of the wind turbine.

[0198] As shown in Figures 30 and 31, a first sealing element 18f is provided between the air outlet 21f and the support ring 12f. The first sealing element 18f is configured as a first sealing ring, which is sleeved on the outer periphery of the support ring 12f to seal between the air outlet 21f and the support ring 12f. This ensures that while the air outlet 21f can rotate relative to the support ring 12f, the airflow will not flow out from the gap between the two, and the airflow will flow into the inner cavity of the air outlet 21f from the inner ring side of the support ring 12f.

[0199] A second sealing element 19f is also provided at the air outlet end of the rotating cylinder. The second sealing element 19f is a rubber ring. A stepped portion is formed on the inner side of the ring body 121f of the support ring 12f, and the first sealing element 18f is sleeved on the outer side of the stepped portion. One end of the rubber ring is sleeved on the outer circumference of the air outlet end of the rotating cylinder, and the other end abuts against the inner side of the stepped portion, so that the rotating cylinder can still ensure a reliable seal with the support ring 12f during rotation, allowing the airflow to flow from the inner ring side of the rotating cylinder to the inner ring side of the support ring 12f.

[0200] Furthermore, multiple guide posts 16f protrude from the support ring 12f, and multiple telescopic springs 17f are fitted around each guide post 16f. The two ends of each telescopic spring 17f abut against the support ring 12f and the telescopic ring 15f, respectively. When the accessory 100f is aligned with the fan body, the abutting action at the connection point of the fan body pushes the telescopic ring 15f to move, exposing multiple connectors 131f for engagement with the connecting parts on the fan body. At this time, each telescopic spring 17f is in an elastic, energy-storing state. When the accessory 100f is removed from the fan body, the elastic restoring force of the multiple telescopic springs 17f pushes the telescopic ring 15f to move and reset, thus re-covering the multiple connectors 131f and protecting them.

[0201] Furthermore, a locking part 141f is provided on the outer periphery of the locking cylinder 14f. When the telescopic ring 15f is in the first working state, the locking part 141f is located inside the telescopic ring 15f; when the telescopic ring 15f is in the second working state, the locking part 141f is exposed outside the telescopic ring 15f. The locking part 141f is adapted to engage with the mating part on the fan body in a wedge shape, so that when the accessory 100f is in contact with the fan body, the telescopic ring 15f can be driven to switch from the first working state to the second working state. Under the action of the locking part 141f and the mating part, the telescopic ring 15f is driven to rotate, so that the locking part 141f is adapted to engage with the fastening part inside the fan body, thereby fixing the accessory 100f to the fan body.

[0202] The locking part 141f includes a locking protrusion 1411f protruding from the outer periphery of the locking cylinder 14f. The locking protrusion 1411f has a first wedge-shaped surface and a limiting groove is provided at the interface of the fan body. A second wedge-shaped surface is formed in the limiting groove to wedge with the first wedge-shaped surface. When the accessory 100f is inserted into the interface of the fan body, the second wedge-shaped surface gradually wedges with the first wedge-shaped surface, thereby driving the locking cylinder 14f to rotate relative to the fan body. This causes the overlap area between the second wedge-shaped surface and the first wedge-shaped surface to gradually increase along the axial direction of the interface of the fan body, forming a stop fit in the axial direction and restricting the movement of the accessory 100f relative to the fan body.

[0203] Furthermore, multiple locking protrusions 1411f are provided, and these protrusions 1411f and multiple limiting grooves are arranged in a one-to-one correspondence. The accessory 100f and the fan body form multiple stop-fitting joints in the axial direction, which further ensures the stability of the accessory 100f installation.

[0204] This application also provides a molding device, which includes a blower body and the aforementioned accessory 100f. The accessory 100f is detachably connected to the blower body, making it easier to assemble and disassemble the accessory 100f from the blower body. The blower body can be configured as a blower.

[0205] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structure made using the content of this application's specification and drawings, or directly or indirectly applied to other related technical fields, is similarly included within the patent protection scope of this application.
