Description

Technical Field

[0001] This utility model relates to the technical field of hair styling tools, specifically to a locking structure, accessories, a blower, and hair styling appliances. Background Technology

[0002] Hair styling tools include hair dryers and accessories, used for drying and styling hair. A typical hair dryer comes with multiple accessories, such as nozzles, straighteners, and curling irons, which often need to be disassembled and replaced. Traditional hair dryers use magnetic attachments to easily separate accessories, but this method is not secure and accessories can easily fall off. Other hair dryers use clips to connect accessories, but this makes disassembly and replacement more difficult, increasing the user's difficulty in removing and replacing accessories. Furthermore, repeated disassembly and reassembly can lead to connection failure and loosening of accessories, resulting in a poor user experience. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the main purpose of this utility model is to provide a locking structure, accessories, blower and hair styling tools, which aims to solve the problem that the connection between the blower and accessories of traditional hair styling tools is unreliable, easy to fail or even fall off, affecting the user experience of hair styling tools.

[0004] To achieve the above objectives, this utility model proposes a locking structure suitable for detachable connection to a blower device, the locking structure comprising:

[0005] Mounting base;

[0006] A first locking structure is movably disposed on the mounting base and has a first working position adapted to be inserted into the plug-in portion of the blower to restrict the mounting base from rotating in the circumferential direction relative to the blower, and a second working position disengaged from the plug-in portion. The first locking structure is provided with a first mating portion.

[0007] The second locking structure is provided on the mounting base and is adapted to be locked with the second mating part on the blower, for preventing the mounting base from dislodging from the blower along its axial direction.

[0008] A rotating sleeve is rotatably disposed on the outside of the mounting base and has a locked state and an unlocked state. The rotating sleeve is provided with an unlocking part that cooperates with the first mating part.

[0009] When the rotating sleeve rotates and switches from the locked state to the unlocked state, the rotating sleeve has a first stroke segment that rotates relative to the mounting base and a second stroke segment that drives the mounting base to rotate as well. When in the first stroke segment, the first locking structure is driven to move from the first working position to the second working position and remain in the second working position under the cooperation of the unlocking part and the first mating part. When in the second stroke segment, the second locking structure is driven to disengage from the second mating part.

[0010] Optionally, the first locking structure includes a locking plate having a travel along the axial direction of the mounting base. The rotating sleeve rotates relative to the mounting base and, under the action of the unlocking part and the first mating part, drives the locking plate to reciprocate along the axial direction of the mounting base.

[0011] Optionally, the unlocking part includes a first wedge-shaped protrusion disposed on the inner side of the rotating sleeve, and the first mating part includes a second wedge-shaped protrusion disposed on the locking plate, wherein the first wedge-shaped protrusion and the second wedge-shaped protrusion are configured to engage in a wedge shape.

[0012] When the rotating sleeve is in the locked state, the first wedge-shaped boss and the second wedge-shaped boss are misaligned along the axial direction of the mounting base; when the rotating sleeve switches from the locked state to the unlocked state, the first wedge-shaped boss abuts against the second wedge-shaped boss along the wedge-in direction, driving the locking plate to move along the axial direction of the mounting base in a direction away from the blower.

[0013] Optionally, the first locking structure further includes an elastic reset member, which connects the locking plate and the mounting base, and is used to allow the locking plate to automatically reset from the second working position to the first working position when the unlocking part and the first mating part are separated.

[0014] Optionally, the locking structure further includes an elastic limiting member, which abuts against the mounting base and the rotating sleeve;

[0015] When the first locking structure moves to the second working position, the elastic limiting member is in an elastic energy storage state and is located at the end of its elastic movement stroke. When the rotating sleeve continues to rotate under the action of external force to enter the second stroke segment, the mounting base can be driven to rotate together under the abutting action of the elastic limiting member, so that the second locking structure is suitable for disengaging from the second mating part. When the external force on the rotating sleeve is removed, the rotating sleeve can rotate in the opposite direction under the action of the elastic restoring force of the elastic limiting member, so that the first locking structure can return to the first working position.

[0016] Optionally, the elastic limiting member is configured as a torsion spring, a first limiting rib is provided on the peripheral side wall of the mounting base, a second limiting rib is provided on the inner side of the rotating sleeve, the first limiting rib and the second limiting rib are arranged at intervals along the circumference of the mounting base, and the two torsion arms of the torsion spring abut against the first limiting rib and the second limiting rib respectively.

[0017] Optionally, the mounting base is hollow, and the second locking structure includes a limiting groove on the peripheral side wall of the mounting base, with a clearance notch on the side of the limiting groove facing the blower, such that the first groove wall of the limiting groove with the clearance notch is suspended along the circumference of the mounting base; and / or,

[0018] The mounting base has an annular protrusion extending circumferentially on its outer periphery to divide it into a first connecting segment and a second connecting segment. A rotating sleeve is fitted onto the outer periphery of the first connecting segment. The first locking structure is located on the first connecting segment and is at least partially extendable into it. The second locking structure is located on the second connecting segment; and / or...

[0019] The outer periphery of the mounting base has a plurality of first locking protrusions, which are spaced apart along the circumference of the mounting base. The inner side of the rotating sleeve has a plurality of second locking protrusions. When in the locked state, the plurality of first locking protrusions and the plurality of second locking protrusions are engaged in a one-to-one correspondence to prevent the rotating sleeve from disengaging from the end of the mounting base near the accessory.

[0020] This utility model also provides an accessory, which includes the above-described locking structure.

[0021] This utility model also provides a blower device suitable for use with the above-mentioned accessories. The blower device includes a device body, a plug-in portion and a second mating portion disposed on the device body. The plug-in portion is adapted to cooperate with a first locking structure of the accessory to restrict the accessory from moving circumferentially relative to the device body. The second mating portion is adapted to cooperate with a second locking structure of the accessory to restrict the accessory from moving radially relative to the device body.

[0022] This utility model also provides a hair styling appliance, including the above-mentioned accessories and the above-mentioned hair dryer.

[0023] The technical solution provided by this utility model has the following beneficial effects:

[0024] The locking structure provided by this utility model is used for detachable connection accessories and blower equipment. The locking structure includes a mounting base, a first locking structure, a second locking structure, and a rotating sleeve. The mounting base connects the accessory and the blower equipment. The first locking structure, inserted into the blower equipment, restricts the circumferential rotation of the mounting base relative to the blower equipment, thus limiting the mounting base in the circumferential direction. The second locking structure cooperates with the blower equipment to prevent the mounting base from detaching from the blower equipment axially, thus limiting the mounting base in the axial direction. This ensures that the mounting base and the blower equipment are completely limited in both the circumferential and axial directions, thereby ensuring reliable installation of the accessory on the blower equipment. Furthermore, the rotating sleeve can lock the first locking structure. The first locking structure unlocks from the second locking structure. Specifically, when the rotating sleeve rotates and switches from the locked state to the unlocked state, the rotating sleeve has a first stroke segment relative to the mounting base and a second stroke segment that drives the mounting base to rotate as well. In the first stroke segment, the first locking structure is driven to move from the first working position to the second working position and remain in the second working position under the cooperation of the unlocking part and the first mating part. In the second stroke segment, the second locking structure is driven to disengage from the second mating part, so that the mounting base can be completely unlocked from the blower in both the circumferential and axial directions. The mounting base can be detached from the blower, allowing the accessory to be easily removed from the blower. The assembly and disassembly of the accessory are simpler and more convenient. When the accessory is fixed to the blower, the double locking connection ensures a more stable and reliable connection between the accessory and the blower, making it less likely to fall off and improving the user experience.

[0037] This utility model provides a locking structure 100 and an accessory 1000. The accessory 1000 includes the locking structure 100, which is suitable for detachable connection to a blower, so that the accessory 1000 can be better installed on the blower.

[0038] Specifically, please refer to Figures 1 to 2 In this embodiment, the locking structure 100 includes a mounting base 1, a first locking structure 2, a second locking structure 3, and a rotating sleeve 4. The mounting base 1 has two axial ends adapted to connect the accessory 1000 and the blower, respectively. The first locking structure 2 is movably mounted on the mounting base 1 and has a first working position adapted to engage with the insertion part 201 of the blower to restrict the mounting base 1 from rotating circumferentially relative to the blower, and a second working position disengaged from the insertion part 201. The first locking structure 2 has a first mating part 22. The second locking structure 3 is mounted on the mounting base 1 and adapted to lock into the second mating part 202 of the blower, restricting the mounting base 1 from rotating circumferentially. The blower is disengaged; the rotating sleeve 4 is rotatably fitted onto the outside of the mounting base 1, and has a locked state and an unlocked state. The rotating sleeve 4 is provided with an unlocking part 41 that cooperates with the first mating part 22. When the rotating sleeve 4 rotates and switches from the locked state to the unlocked state, the rotating sleeve 4 has a first stroke segment that rotates relative to the mounting base 1, and a second stroke segment that drives the mounting base 1 to rotate together. When in the first stroke segment, the first locking structure 2 is driven to move from the first working position to the second working position and remain in the second working position under the cooperation of the unlocking part 41 and the first mating part 22. When in the second stroke segment, the second locking structure 3 is driven to disengage from the second mating part 202.

[0039] In this embodiment, the first locking structure 2, inserted into the blower, restricts the circumferential rotation of the mounting base 1 relative to the blower, thus limiting the mounting base 1 in the circumferential direction. The second locking structure 3, cooperating with the blower, restricts the mounting base 1 from axially disengaging from the blower, thus limiting the mounting base 1 in the axial direction. This ensures that the mounting base 1 and the blower are completely limited in both the circumferential and axial directions, guaranteeing reliable installation of the accessory 1000 on the blower. Furthermore, the first locking structure 2 and the second locking structure 3 can be unlocked by rotating the sleeve 4. Specifically, the sleeve 4 rotates from the locked state to the unlocked state. During state switching, the rotating sleeve 4 has a first stroke segment that rotates relative to the mounting base 1, and a second stroke segment that drives the mounting base 1 to rotate as well. In the first stroke segment, the first locking structure 2 is driven to move from the first working position to the second working position and remains in the second working position under the cooperation of the unlocking part 41 and the first mating part 22. In the second stroke segment, the second locking structure 3 is driven to disengage from the second mating part 202, allowing the mounting base 1 to be completely unlocked from the blower in both the circumferential and axial directions. The mounting base 1 can then be detached from the blower, allowing the accessory 1000 to be easily removed from the blower. The assembly and disassembly of the accessory 1000 are both simpler and more convenient. Furthermore, when the accessory 1000 is fixed to the blower, the double locking connection ensures a more stable and reliable connection between the accessory 1000 and the blower, preventing it from easily falling off and enhancing the user experience.

[0040] The blower can be set as a hair dryer, and the accessory 1000 can be set as a nozzle, straightener, curling iron, etc.

[0041] Preferably, the mounting base 1 is generally cylindrical. When the hair styling appliance is set to one of its operating states, the hair dryer is located at the bottom end of the mounting base 1, that is, the air outlet of the hair dryer is connected to the bottom opening of the mounting base 1; the accessory 1000 is located at the top end of the mounting base 1. For ease of explanation, the description of the orientation in this utility model is based on the hair styling appliance in this operating state, and other operating states can be adapted accordingly.

[0042] The first locking structure 2 is mainly used to restrict the relative movement of the mounting base 1 and the blower in the circumferential direction. Preferably, it is combined with... Figure 2 and Figure 3As shown, the first locking structure 2 includes a locking plate 21, which has a travel along the axial direction of the mounting base 1. The rotating sleeve 4 rotates relative to the mounting base 1 and, under the action of the unlocking part 41 and the first mating part 22, drives the locking plate 21 to reciprocate along the axial direction of the mounting base 1. A mounting groove is provided on the outer periphery of the mounting base 1, and the locking plate 21 is accommodated in the mounting groove. The outer surface of the locking plate 21 is approximately on the same surface as the outer periphery of the mounting base 1, or the locking plate 21 protrudes slightly from the mounting groove and does not interfere with the rotation of the rotating sleeve 4. By moving the locking plate 21 axially, it can be inserted into or separated from the insertion part 201 of the equipment body, thereby allowing the mounting base 1 and the equipment body to be relatively fixed or rotated relative to each other in the circumferential direction. This makes the fit between the locking plate 21 and the equipment body more stable and reliable when the locking plate 21 is in the first position, ensuring that the accessory 1000 will not wobble relative to the equipment body.

[0043] It is understandable that there are many ways to adjust the axial movement of the locking plate 21. Preferably, the rotation of the rotating sleeve 4 can be converted into axial displacement of the locking plate 21. Specifically, in conjunction with Figure 2 and Figure 4 As shown, the unlocking part 41 includes a first wedge-shaped boss 411 located inside the rotating sleeve 4, and the first mating part 22 includes a second wedge-shaped boss 221 located on the locking plate 21. The first wedge-shaped boss 411 and the second wedge-shaped boss 221 are wedge-shaped and mated together. When the rotating sleeve 4 is in the locked state, the first wedge-shaped boss 411 and the second wedge-shaped boss 221 are misaligned along the axial direction of the mounting base 1. Furthermore, when the rotating sleeve 4 is in the locked state, the ends of the first wedge-shaped boss 411 and the second wedge-shaped boss 221 that are close to each other are chamfered to facilitate the wedge-shaped engagement of the first wedge-shaped boss 411 and the second wedge-shaped boss 221. When the rotating sleeve 4 switches from the locked state to the unlocked state, the first wedge-shaped boss 411 abuts against the second wedge-shaped boss 221 along the wedge-in direction, driving the locking plate 21 to move away from the blower along the axial direction of the mounting base 1, so that the first locking structure 2 can disengage from the plug-in part 201 of the blower, thereby unlocking the mounting base 1 in the circumferential direction.

[0044] Furthermore, the first locking structure 2 also includes an elastic reset member (not shown in the drawings). The elastic reset member connects the locking plate 21 and the mounting base 1, and is used to automatically reset the locking plate 21 from the second working position to the first working position when the unlocking part 41 and the first mating part 22 are separated, avoiding the need to manually readjust the position of the locking plate 21 for locking, thus simplifying the operation. The elastic reset member can be configured as a telescopic spring. When the rotating sleeve 4 rotates under external force (such as manually), the first wedge-shaped boss 411 abuts against the bottom of the second wedge-shaped boss 221, driving the locking plate 21 upward and compressing the telescopic spring, allowing the locking plate 21 to separate from the insertion part 201. When the first wedge-shaped boss 411 and the second wedge-shaped boss 221 are completely misaligned in the vertical direction, the first wedge-shaped boss 411 no longer abuts against the second wedge-shaped boss 221. Under the elastic extension force of the telescopic spring, the locking plate 21 can be pushed downward, so that the locking plate 21 can be inserted into the plug-in part 201 on the blower again, so that the locking structure 100 is in a locked state.

[0045] It is understandable that when the rotating sleeve 4 enters the second stroke segment, in order to allow the mounting base 1 and the rotating sleeve 4 to rotate together, in one embodiment, a driving part can be provided on the rotating sleeve 4, and a transmission part can be provided on the mounting base 1. The driving part abuts and pushes the transmission part, thereby driving the mounting base 1 to rotate together under the pushing action of the rotating sleeve 4. The driving part is a first protrusion provided on the inner side wall of the rotating sleeve 4, and the transmission part is a second protrusion provided on the outer side wall of the mounting base 1. When the locking plate 21 is in the second working position, the first protrusion abuts against one side of the second protrusion along the circumference of the mounting base 1. When the rotating sleeve 4 is continuously subjected to external force to rotate, the first protrusion pushes the second protrusion, causing the mounting base 1 and the rotating sleeve 4 to rotate together until the second locking structure 3 unlocks from the second mating part 202 of the blower.

[0046] In another embodiment, combined Figure 2 and Figure 3As shown, the locking structure 100 also includes an elastic limiting member 5, which abuts against the mounting base 1 and the rotating sleeve 4. When the first locking structure 2 moves to the second working position, the elastic limiting member 5 is in an elastic energy storage state and is located at the end of its elastic movement stroke. When the rotating sleeve 4 continues to rotate under the action of external force to enter the second stroke segment, the mounting base 1 can be driven to rotate together under the abutting action of the elastic limiting member 5, so that the second locking structure 3 is suitable for disengaging from the second mating part 202. When the external force on the rotating sleeve 4 is removed, the rotating sleeve 4 can rotate in the opposite direction under the action of the elastic restoring force of the elastic limiting member 5, so that the first locking structure 2 can return to the first working position. The elastic limiting member 5 not only allows the mounting base 1 and the rotating sleeve 4 to rotate together in the second stroke segment, but also allows the rotating sleeve 4 and the locking plate to automatically reset after the mounting base 1 is removed from the blower, making operation more convenient and making it easier to reinstall the mounting base 1 on the blower.

[0047] More preferably, the elastic limiting member 5 is a torsion spring 51. A first limiting rib 11 protrudes from the peripheral sidewall of the mounting base 1, and a second limiting rib 42 protrudes from the inner side of the rotating sleeve 4. The first limiting rib 11 and the second limiting rib 42 are spaced apart along the circumference of the mounting base 1, and the two torsion arms of the torsion spring 51 abut against the first limiting rib 11 and the second limiting rib 42, respectively. When the rotating sleeve 4 rotates to complete the first stroke segment, the second limiting rib 42 torsionally compresses the torsion spring 51. When the first stroke segment is completely completed, the torsion spring 51 no longer torsional and stores energy, and can then push the first limiting rib 11 through the torsion spring 51, thereby driving the mounting base 1 to rotate as well.

[0048] Of course, the methods for driving the mounting base 1 and the rotating sleeve 4 to rotate together include, but are not limited to, those described above. In other embodiments, a combination of the two methods described above can be used to ensure a more accurate and reliable driving position for the mounting base 1.

[0049] The second locking structure 3 is mainly used to define the relative positions of the mounting base 1 and the blower in the axial direction. Preferably, it is combined with... Figure 2 and Figure 3As shown, the second locking structure 3 includes a limiting groove 31 provided on the peripheral side wall of the mounting base 1. The mounting base 1 is hollow and open on the side facing the blower. At least a portion of the mounting base 1 can extend into the blower, allowing the limiting groove 31 to engage with the limiting protrusion 2021 of the blower. A clearance notch 32 is provided on the side of the limiting groove 31 facing the blower, so that the first groove wall of the limiting groove 31 with the clearance notch 32 is suspended along the circumference of the mounting base 1. The limiting protrusion 2021 of the blower can extend into the limiting groove 31 from the clearance notch 32, and after the mounting base 1 and the blower rotate relative to each other, the limiting protrusion 2021 can engage with the first groove wall, thereby restricting the relative axial movement of the mounting base 1 and the blower.

[0050] The second locking structure 3 can be provided in multiples, and the multiple second locking structures 3 are arranged at intervals along the circumference of the mounting base 1. The blower can be provided with multiple second mating parts 202, and the connection between the mounting base 1 and the blower is more stable and reliable by the multiple second locking structures 3 engaging with the multiple second mating parts 202 one by one.

[0051] Moreover, such as Figure 2 As shown, an annular boss 12 extending circumferentially is provided on the outer periphery of the mounting base 1 to divide the mounting base 1 into a first connecting segment and a second connecting segment. A rotating sleeve 4 is fitted onto the outer periphery of the first connecting segment. A first locking structure 2 is provided on the first connecting segment and can at least partially extend into the first connecting segment. A second locking structure 3 is provided on the second connecting segment. Specifically, the second connecting segment extends at least partially or completely into the blower, such that the annular boss 12 abuts against the mating end of the blower. When installing accessory 1000, the locking plate 21 can be aligned with the plug-in part 201 on the blower, and then the second connecting section can be inserted into the blower downwards. When the annular boss 12 abuts against the docking end of the blower, the mounting base 1 can be rotated. When the mounting base 1 can no longer rotate, the limiting protrusion 2021 inside the blower is completely locked in the corresponding limiting groove 31, so that accessory 1000 can be completely fixed on the blower. The assembly is simple and convenient. When disassembling accessory 1000, the rotating sleeve 4 can be rotated. When the mounting base 1 rotates together and can no longer rotate, the entire accessory 1000 can be completely disassembled. The disassembly operation is also very simple.

[0052] In addition, multiple first locking protrusions 13 protrude from the outer periphery of the mounting base 1. These first locking protrusions 13 are spaced apart circumferentially along the mounting base 1 and are all offset from the locking plate 21 circumferentially. Multiple second locking protrusions 43 protrude from the inner side of the rotating sleeve 4. When locked, the multiple first locking protrusions 13 and the multiple second locking protrusions 43 are engaged in a one-to-one manner to prevent the rotating sleeve 4 from disengaging from the end of the mounting base 1 near the accessory 1000. The rotating sleeve 4 is generally cylindrical with open ends. The opening at the end of the rotating sleeve 4 facing away from the blower has an inwardly extending edge that abuts downward against the end of the mounting base 1. The second locking protrusions 43 abut against the first locking protrusions 13 upward, thereby positioning the rotating sleeve 4 axially on the mounting base 1. Furthermore, when the multiple first locking protrusions 13 and the multiple second locking protrusions 43 abut against each other, the rotation of the rotating sleeve 4 can be guided, making the rotating sleeve 4 more stable during rotation.

[0053] This utility model also provides a hair dryer for use with the aforementioned accessory 1000. The accessory 100 can be quickly attached and detached from the hair dryer via a locking structure 100, making it more convenient to use. Specifically, the hair dryer includes a main body, a plug-in portion 201, and a second mating portion 202 provided on the main body. The plug-in portion 201 is adapted to engage with the first locking structure 2 of the accessory 1000 to restrict the accessory 1000 from moving circumferentially relative to the main body. The second mating portion 202 is adapted to engage with the second locking structure 3 of the accessory 1000 to restrict the accessory 1000 from moving radially relative to the main body. This ensures a stable and reliable connection between the accessory 1000 and the hair dryer, while also making attachment and detachment easier.

[0054] Preferably, such as Figure 5 As shown, the main body of the device includes a cylindrical air outlet structure 200, a plug-in part 201 including a plug-in groove 2011 on the inner side wall of the air outlet structure 200, and a second mating part 202 including a limiting protrusion 2021 on the inner side wall of the air outlet structure 200. The air outlet structure 200 is connected to the mounting base 1, and the airflow blown out by the air blower can enter the accessory 1000 from the mounting base 1. The specific disassembly and assembly method of the accessory 1000 has been described above and will not be repeated here.

[0055] The air outlet structure 200 can be integrally installed with the main body of the equipment. Alternatively, the air outlet structure 200 can be detachably installed on the main body of the equipment.

[0056] This utility model also provides a hair styling appliance, including the aforementioned blower and accessory 1000. The hair styling appliance may include multiple sets of accessories 1000. The locking structures 100 of the multiple sets of accessories 1000 are uniformly arranged and can all be connected to the accessories 1000, making it easier to replace the accessories 1000 and making the operation of the hair styling appliance simpler and more convenient, thus improving the user experience.

[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.

When the rotating sleeve rotates and switches from the locked state to the unlocked state, the rotating sleeve has a first stroke segment that rotates relative to the mounting base and a second stroke segment that drives the mounting base to rotate as well. When in the first stroke segment, the first locking structure is driven to move from the first working position to the second working position and remain in the second working position under the cooperation of the unlocking part and the first mating part. When in the second stroke segment, the second locking structure is driven to disengage from the second mating part.

2. The locking structure as described in claim 1, characterized in that, The first locking structure includes a locking plate having a travel along the axial direction of the mounting base. The rotating sleeve rotates relative to the mounting base and, under the action of the unlocking part and the first mating part, drives the locking plate to reciprocate along the axial direction of the mounting base.

3. The locking structure as described in claim 2, characterized in that, The unlocking part includes a first wedge-shaped protrusion disposed on the inner side of the rotating sleeve, and the first mating part includes a second wedge-shaped protrusion disposed on the locking plate. The first wedge-shaped protrusion and the second wedge-shaped protrusion are configured to engage in a wedge shape. When the rotating sleeve is in the locked state, the first wedge-shaped boss and the second wedge-shaped boss are misaligned along the axial direction of the mounting base; when the rotating sleeve switches from the locked state to the unlocked state, the first wedge-shaped boss abuts against the second wedge-shaped boss along the wedge-in direction, driving the locking plate to move along the axial direction of the mounting base in a direction away from the blower.

4. The locking structure as described in claim 2, characterized in that, The first locking structure further includes an elastic reset member, which connects the locking plate and the mounting base, and is used to allow the locking plate to automatically reset from the second working position to the first working position when the unlocking part and the first mating part are separated.

5. The locking structure as described in claim 1, characterized in that, The locking structure further includes an elastic limiting member, which abuts between the mounting base and the rotating sleeve; When the first locking structure moves to the second working position, the elastic limiting member is in an elastic energy storage state and is located at the end of its elastic movement stroke. When the rotating sleeve continues to rotate under the action of external force to enter the second stroke segment, the mounting base can be driven to rotate together under the abutting action of the elastic limiting member, so that the second locking structure is suitable for disengaging from the second mating part. When the external force on the rotating sleeve is removed, the rotating sleeve can rotate in the opposite direction under the action of the elastic restoring force of the elastic limiting member, so that the first locking structure can return to the first working position.

6. The locking structure as described in claim 5, characterized in that, The elastic limiting member is configured as a torsion spring. A first limiting rib is protruding on the peripheral side wall of the mounting base, and a second limiting rib is protruding on the inner side of the rotating sleeve. The first limiting rib and the second limiting rib are arranged at intervals along the circumference of the mounting base, and the two torsion arms of the torsion spring abut against the first limiting rib and the second limiting rib, respectively.

7. The locking structure as described in claim 1, characterized in that, The mounting base is hollow, and the second locking structure includes a limiting groove on the peripheral side wall of the mounting base. The limiting groove has a clearance notch on the side facing the blower, such that the first groove wall with the clearance notch is suspended circumferentially along the mounting base; and / or, The mounting base has an annular protrusion extending circumferentially on its outer periphery to divide it into a first connecting segment and a second connecting segment. A rotating sleeve is fitted onto the outer periphery of the first connecting segment. The first locking structure is located on the first connecting segment and is at least partially extendable into it. The second locking structure is located on the second connecting segment; and / or... The outer periphery of the mounting base has a plurality of first locking protrusions, which are spaced apart along the circumference of the mounting base. The inner side of the rotating sleeve has a plurality of second locking protrusions. When in the locked state, the plurality of first locking protrusions and the plurality of second locking protrusions are engaged in a one-to-one correspondence to prevent the rotating sleeve from disengaging from the end of the mounting base near the accessory.

8. An accessory, characterized in that, Includes the locking structure as described in any one of claims 1 to 7.

9. A blower device, suitable for use with the accessory as described in claim 8, characterized in that, The blower includes a main body, a plug-in portion and a second mating portion disposed on the main body, the plug-in portion being adapted to engage with a first locking structure of an accessory to restrict the accessory from moving circumferentially relative to the main body, and the second mating portion being adapted to engage with a second locking structure of the accessory to restrict the accessory from moving radially relative to the main body.

10. A hair styling tool, characterized in that, Includes the attachments as described in claim 8 and the blower as described in claim 9.
