[0001] The present application relates to the technical field of care equipment, and in particular to a hair care equipment. Background Art

[0002] Hair care equipment can be used to dry and style hair. For example, a user can use the hair care equipment to dry wet hair and style the hair during the drying process.

[0003] The hair care device in the related art generally includes a plurality of accessories for styling, a blower body and a grip, wherein the blower body can provide airflow to the accessories, and the user holds the grip to drive the blower body and the styling part to move to style the hair.

[0004] However, when the air outlet direction or usage angle of the accessory needs to be adjusted, or when it is frequently pulled by external force during use, the direction of the accessory of the hair care device in the above-mentioned related technology cannot be fixed when connected to the fan body, thereby affecting the user's usage experience; when the air outlet direction or usage angle of the accessory does not need to be adjusted, the user needs to easily separate the accessory from the main body to meet the user's usage needs in other situations. Utility Model Content

[0005] An embodiment of the present application provides a hair care device, which is used to solve the technical problem that when the air outlet direction or usage angle of the accessory needs to be adjusted, or when it is frequently pulled by external force during use, some accessories of the hair care device in the above-mentioned related technology cannot be fixed in direction when connected to the fan body, thereby affecting the user's usage experience.

[0006] In order to achieve the above objectives, the present application provides the following technical solutions:

[0007] A first aspect of an embodiment of the present application provides a hair care device, which includes: a fan main body; an accessory, the fan main body is used to provide an airflow to the accessory, and the accessory is used to shape a target object through the airflow; a stop mechanism, the stop mechanism includes a first structure and / or a second structure; when the stop mechanism includes the first structure and the second structure, the first structure and the second structure are respectively arranged on the fan main body and the accessory, and after the accessory is connected to the fan main body, the first structure and the second structure cooperate to fix the accessory relative to the direction of the fan main body; when the stop mechanism includes the first structure or the second structure, the first structure or the second structure is arranged on one of the fan main body and the accessory, and after the accessory is connected to the fan main body, the accessory may be not fixed relative to the direction of the fan main body.

[0008] The hair care device provided in the embodiment of the present application includes a fan body, an accessory and a rotation-stopping mechanism. When the accessory connected to the fan body used by the user needs to adjust the air outlet direction or the use angle, the first structure and the second structure of the rotation-stopping mechanism are respectively arranged on the fan body and the accessory. After the accessory is connected to the fan body, the direction of the accessory relative to the fan body can be fixed, thereby preventing the accessory from rotating or moving as a whole relative to the fan body during the process of adjusting the air outlet direction or the use angle of the accessory, causing the air outlet direction of the accessory to be uncontrollable, and the hair flying when the user styles or blow-dries. At the same time, the connection stability between the accessory and the fan body is improved, thereby improving the user's usage experience.

[0009] When the accessories connected to the fan body used by the user do not need to adjust the air outlet direction or the angle of use, or the type of accessories does not change with the change of wind direction, that is, any air outlet direction can achieve the purpose of the accessory, such as an essence air nozzle, an atomization air nozzle, etc., the first structure or the second structure can be set on only one of the fan body and the accessory. In this case, after the fan body and the accessory are connected, the accessory can achieve fixed direction relative to the fan body without the cooperation of the first structure and the second structure.

[0010] To sum up, the hair care device of the present application can flexibly adjust the fixing method between the accessory and the fan body according to the different styling needs of the user, so as to prevent the accessory from rotating or moving relative to the fan body when the user needs to adjust the air outlet direction and usage angle of the accessory, or when it is frequently pulled by external force during use. It can also achieve that when the user does not need to adjust the air outlet direction and usage angle of the accessory, the connection state between the accessory and the fan body is not constrained, thereby improving the flexibility of the connection between the fan body and the accessory, and can improve the flexibility and practicality of use of the hair care device.

[0011] The second aspect of the embodiment of the present application provides a hair care device, which includes: a fan main body; two or more accessories, the accessories are connected to the fan main body, the fan main body is used to provide airflow to the accessories, and the accessories are used to shape the target object through the airflow; at least two of the accessories have different shaping methods for the target object; a stop mechanism, the stop mechanism includes a first structure and at least one second structure, the first structure is arranged on the fan main body; the second structure is arranged on some of the accessories, the first structure cooperates with the second structure, so that the accessories provided with the second structure are fixed relative to the direction of the fan main body; the second structure is not arranged on some of the accessories, so that after the accessories without the second structure are connected to the fan main body, the accessories are not fixed relative to the direction of the fan main body.

[0012] The embodiment of the present application provides a hair care device including a blower main body, two or more accessories, and a rotation-stopping mechanism including a first structure and at least one second structure. By using multiple accessories to cooperate with the blower main body, when a user performs different hair styles, different accessories can be used to cooperate with the blower main body, thereby meeting the user's needs for performing various hair styles, enriching the styling function of the hair care device and improving the practicality of the hair care device.

[0013] Furthermore, when the user uses an accessory with a second structure to cooperate with the fan main body, the second structure and the first structure cooperate with each other to fix the direction of the accessory relative to the fan main body, thereby reducing the rotation or movement of the accessory with the second structure relative to the fan main body, and improving the connection stability between the accessory with the second structure and the fan main body. When the user uses an accessory without a second structure to cooperate with the fan main body, the accessory can be fixed relative to the fan main body without the cooperation of the first structure and the second structure, thereby achieving no constraint on the connection state between the accessory and the fan main body.

[0014] To sum up, the hair care device of the present application can use accessories with or without the second structure to cooperate with the fan body according to different styling needs of users, thereby being able to flexibly adjust the fixing method between the accessory and the fan body to achieve the situation that when the user needs to adjust the air outlet direction and the use angle of the accessory, the accessory is prevented from rotating or moving relative to the fan body, and when the user does not need to adjust the air outlet direction and the use angle of the accessory, the connection state between the accessory and the fan body is not constrained, thereby improving the flexibility of the connection between the fan body and the accessory, and being able to improve the flexibility and practicality of the hair care device.

[0015] Based on the above technical solution, the present application can also be improved as follows.

[0016] In a possible implementation, the first structure includes at least one groove, and the second structure includes at least one protrusion, and the groove and the protrusion cooperate to fix the accessory relative to the direction of the fan body.

[0017] In this way, the shapes of the groove and the protrusion match each other, so that the groove and the protrusion can cooperate with each other in a specific way, thereby achieving precise positioning between the accessory and the fan body, so that the accessory and the fan body can be accurately installed during the assembly process.

[0018] The matching of the groove and the convex part can provide a larger contact area and a tighter connection, thereby increasing the stability and load-bearing capacity of the connection between the accessory and the fan body. The friction and shape matching between the groove and the convex part can prevent the accessory and the fan body from loosening or falling off during use.

[0019] The structure of the groove and the protrusion is relatively simple, easy to manufacture and assemble, and can reduce the manufacturing cost of the anti-rotation mechanism, thereby reducing the manufacturing cost of the hair care device.

[0020] Alternatively, the first structure includes at least one first magnetic material, the second structure includes at least one second magnetic material compatible with the first magnetic material, and the first magnetic material and the second magnetic material cooperate to fix the accessory relative to the direction of the fan body.

[0021] In this way, the magnetic connection between the first magnetic material and the second magnetic material can realize non-contact connection between the accessory and the blower body, and can realize connection between the accessory and the blower body within a certain distance range through the magnetic field or magnetic mutual attraction between the first magnetic material and the second magnetic material without the need for excessive connection operations, thereby improving the connection convenience between the accessory and the blower body and the ease of use of the hair care device.

[0022] Furthermore, the magnetic connection between the first magnetic material and the second magnetic material reduces the wear caused by the contact friction between the first structure and the second structure, thereby increasing the service life of the first structure and the second structure and the service life of the hair care device.

[0023] Alternatively, the first structure is an internal thread, and the second structure is an external thread corresponding to the internal thread, and the internal thread and the external thread cooperate to fix the accessory relative to the direction of the fan body.

[0024] In this way, the accessory and the fan body can be connected and fixed in direction by rotation, and the connection method of internal and external threads can enable the connection between the accessory and the fan body to withstand greater tension or shear force, thereby improving the connection strength between the accessory and the fan body, as well as the stability of direction fixation.

[0025] The connection between the internal and external threads has a self-locking function, which can prevent the fan body and accessories from loosening or falling off during use. The bevel design of the internal and external threads can generate friction during connection, making the connection more secure.

[0026] Alternatively, the first structure includes at least one guide groove, and the second structure includes at least one guide slider matched with the guide groove, and the guide groove and the guide slider cooperate to fix the accessory relative to the direction of the fan body.

[0027] In this way, the guide groove and the guide slide block can provide a precise guiding connection method to ensure that the accessories and the fan body can be accurately aligned and positioned when connected.

[0028] In a possible implementation, the first magnetic material is a first magnet, and the second magnetic material is a second magnet or an iron sheet; when the first magnet and the second magnet cooperate with each other, or when the first magnet and the iron sheet cooperate with each other, the directions of the accessory and the fan body are relatively fixed.

[0029] In this way, by setting the first magnetic material as the first magnet and the second magnetic material as the second magnet, a non-contact connection can be achieved through the magnetic connection between the first magnet and the second magnet, and the directions of the accessory and the blower body can be relatively fixed. The connection is achieved through the mutual attraction of the magnetic fields between the first magnet and the second magnet, and no excessive connection operations are required, thereby improving the connection convenience between the accessory and the blower body and the convenience of using the hair care device.

[0030] Furthermore, the magnetic connection between the first magnet and the second magnet reduces the wear caused by the contact friction between the first structure and the second structure, thereby increasing the service life of the first structure and the second structure and the service life of the hair care device.

[0031] In addition, the connection method between the first magnet and the iron sheet can realize the connection between the magnet and the metal structure. When the hair care device has an iron component and the iron component can be reused as the second structure of the anti-rotation mechanism, the number of parts of the hair care device can be reduced, thereby reducing the manufacturing cost of the hair care device.

[0032] In a possible implementation, the internal thread is provided on one of the fan body and the accessory, and the external thread is provided on the other of the fan body and the accessory; when the internal thread and the external thread are connected, the directions of the accessory and the fan body are relatively fixed.

[0033] In this way, the connection mode of the internal thread and the external thread can enable the connection between the accessory and the fan body to withstand a large tensile force or shear force, thereby improving the connection strength between the accessory and the fan body, as well as the stability of directional fixation.

[0034] The connection between the internal and external threads has a self-locking function, which can prevent the fan body and accessories from loosening or falling off during use. The bevel design of the internal and external threads can generate friction during connection, making the connection more secure.

[0035] In a possible implementation, the guide groove is provided on one of the fan body and the accessory, and the guide slider is provided on the other of the fan body and the accessory; the guide groove is provided with a stop portion, and the guide slider stops when it slides along the guide groove to the stop portion, and the accessory and the fan body are relatively fixed.

[0036] In this way, by providing a stopper in the guide groove, the displacement range of the guide slider in the guide groove can be limited, preventing the accessory and the fan body from excessive displacement or offset when connected, thereby ensuring that the accessory and the fan body can be accurately aligned and positioned when connected, thereby improving the accuracy of the connection.

[0037] In a possible implementation, when there are a plurality of the protrusions and a plurality of the grooves, the number of the protrusions is less than or equal to the number of the grooves.

[0038] In this way, by making the number of grooves greater than the number of protrusions, the user can adjust a smaller angle when connecting the accessory to the blower body, so that the protrusions can be aligned and connected with some of the grooves, thereby reducing the difficulty of aligning the protrusions and grooves, making it easier for the user to connect and fix the accessory to the blower body, thereby improving the ease of use of the hair care device and the user's experience.

[0039] The setting of all the above-mentioned anti-rotation mechanisms can realize the anti-rotation function on the one hand, and can also realize the connection between the accessory and the fan body on the other hand, such as the matching of internal and external threads, the matching of magnetic materials, etc. Even if the connection between the accessory and the fan body relies on other connection structures rather than just the above-mentioned anti-rotation mechanism, the setting of the anti-rotation mechanism can also increase the connection stability of the accessory to the fan body and reduce the possibility of the accessory falling off the fan body. In particular, for accessories with larger size or those subjected to more external forces during use, such as curling accessories, the setting of the anti-rotation mechanism has a better effect.

[0040] In a possible implementation, the fan body is provided with an air outlet, and the groove is opened on the wall near the air outlet; the accessory is provided with an air inlet, and the protrusion is correspondingly arranged on the wall near the air inlet of the accessory.

[0041] In this way, by opening a groove on the wall of the fan main body air outlet firmware and opening a convex part on the wall of the accessory air inlet accessory, the groove and the convex part can be matched when the air outlet and the air inlet are connected, thereby improving the connection efficiency between the accessory fan body.

[0042] In a possible implementation, the groove extends along the axial direction of the fan body, and the notch of the groove facing the accessory is semicircular or an inwardly concave arc surface; along the axial direction perpendicular to the fan body, the cross-section of the convex portion is a semicircular or outwardly convex arc surface corresponding to the notch.

[0043] In this way, since the semicircular or arcuate notches and the convex parts with semicircular or arcuate cross sections are easier to achieve accuracy and stability during the manufacturing process, the manufacturing difficulty is relatively low, which can reduce the manufacturing cost and difficulty of the hair care device. In addition, the semicircular notches and the convex parts with semicircular cross sections are less affected by directionality than polygons, so that users can more easily achieve alignment between the grooves and the convex parts, which improves the convenience of using the hair care device.

[0044] In a possible implementation, the groove includes a first groove segment and a second groove segment that are connected to each other; the first groove segment extends along the axial direction of the fan body, one end of the second groove segment is connected to the first groove segment, and the second groove segment extends around the circumference of the fan body; during the connection between the accessory and the fan body, the protrusion moves along the extension direction of the first groove segment and moves along the extension direction of the second groove segment, so that the directions of the accessory and the fan body are relatively fixed.

[0045] In this way, the protrusion is connected to the groove having the first groove segment and the second groove segment, so that when the protrusion is in the first groove segment, the accessory can be fixed in the circumferential direction relative to the fan body. When the protrusion is set in the second groove segment, the accessory can be fixed in the axial direction relative to the fan body, thereby achieving directional fixation of the accessory and the fan body in at least two directions, thereby improving the connection stability between the accessory and the fan body.

[0046] In a possible implementation, the groove is arranged on the wall surface of the fan body along the axial spiral of the fan body; the convex portion is arranged on the wall surface of the fan body along the axial spiral of the fan body, and when the convex portion is matched and connected with the groove, the direction of the accessory and the fan body is fixed.

[0047] In this way, by rotating the convex portion along the extension direction of the groove in a screwing manner, the groove can limit and fix the convex portion in both the axial direction of the fan body and the axial direction around the fan body, so that the accessory and the fan body can be fixed in at least two mutually perpendicular directions, thereby improving the connection stability between the accessory and the fan body, and thereby improving the use stability of the hair care device.

[0048] In one possible implementation, the fan body includes an annular component; the annular component is arranged in the air outlet, the outer wall of the annular component is spaced apart from the outer shell of the fan body, and the outer wall of the annular component and the outer shell of the fan body are spaced apart to form an annular groove; the accessory has a flange that is adapted to the annular groove, and when the accessory is connected to the fan body, the flange is arranged in the annular groove.

[0049] In this way, when the flange is inserted into the annular groove, the annular groove can limit the flange in its radial direction, thereby preventing the accessory from being offset or shaking relative to the axial direction of the fan body when connected to the fan body, thereby improving the connection stability between the accessory and the fan body, and further improving the use stability of the hair care device.

[0050] Furthermore, the design of the annular groove can provide a certain degree of sealing for the connection between the accessory and the fan body, preventing external substances such as dust and water vapor from entering the fan body or the accessory through the connection between the accessory and the fan body, thereby reducing the chance of damage to the internal components of the fan body and the internal components of the accessory, and increasing the service life of the hair care equipment.

[0051] In a possible implementation, the groove is provided on the outer side wall of the annular member, and the protrusion is provided on the inner side wall of the flange;

[0052] Alternatively, the groove is formed on the inner wall of the outer shell at the air outlet of the fan body, and the protrusion is arranged on the outer wall of the flange.

[0053] In this way, by opening a groove on the outer wall of the annular component or the inner wall of the outer shell of the fan main body air outlet, and correspondingly arranging the convex portion on the inner wall or outer wall of the flange, the accessory can be fixed relative to the fan main body while the flange is arranged in the annular groove, thereby further improving the connection stability between the accessory and the fan main body.

[0054] Furthermore, by arranging the groove on the outer side wall of the annular component, the integration degree between the various structures on the fan body can be improved, and by arranging the convex portion on the inner side wall of the flange corresponding to the position of the groove, the convex portion and the groove can be located inside the structure, avoiding the convex portion and the groove from being exposed to the outside of the accessory and the fan body, thereby improving the aesthetics of the accessory and the fan body, and improving the aesthetics of the hair care device and the user experience.

[0055] In a possible implementation, when there are a plurality of grooves, the plurality of grooves are arranged at intervals on the outer side wall of the annular member; when there are a plurality of protrusions, the plurality of protrusions are arranged at intervals on the inner side wall of the flange.

[0056] In this way, by spacing and evenly arranging multiple grooves on the outer wall of the annular component and spacing and evenly arranging multiple protrusions on the inner wall of the flange, the uniformity of force at the connection between the grooves and the protrusions can be improved, and the uniformity of force when the accessory is connected to the fan body can be improved.

[0057] In a possible implementation, the anti-rotation mechanism further includes at least one clamping member, which is disposed in the groove and is used to clamp a protrusion that cooperates with the groove.

[0058] In this way, by arranging a clamping member in the groove to clamp the protrusion in the groove through the clamping member, the protrusion can be clamped in the groove through the clamping force of the clamping member, thereby further improving the connection stability between the accessory and the fan body and preventing the accessory from shaking or rotating relative to the fan body.

[0059] In a possible implementation, the clamping member is an elastic member, and the elastic member is arranged on the inner wall of the groove. When the protrusion is inserted into the groove, the elastic member undergoes elastic deformation and fastens the protrusion in the groove through the elastic deformation force.

[0060] In this way, by setting the clamping member as an elastic member, the structure of the clamping member can be simplified, and the manufacturing process and production cost of the clamping member can be simplified, thereby reducing the manufacturing process and manufacturing cost of the hair care device and improving the practicality of the hair care device.

[0061] In a possible implementation, the accessory includes an adjusting part and a shaping part, the adjusting part rotates relative to the shaping part to adjust the air outlet direction of the shaping part, and the shaping part is used to shape the target object through the airflow; the first structure and the second structure are respectively arranged on the fan body and the shaping part, after the shaping part is connected to the fan body and the adjusting part rotates relative to the shaping part, the first structure and the second structure cooperate to fix the shaping part relative to the fan body.

[0062] In this way, the user can adjust the air outlet direction of the accessory by adjusting the adjustment part. For example, the user can adjust the air outlet direction of the styling part by rotating the adjustment part. When the adjustment part is rotated, the styling part can be fixed relative to the direction of the fan body through the cooperation of the first structure and the second structure, which improves the connection stability between the styling part and the fan body. This can avoid the styling part rotating stably with the adjustment part when the user adjusts the air outlet of the styling part through the adjustment part, thereby improving the user's experience of using the hair care device.

[0063] In a possible implementation, the axis of the fan body is coaxial or parallel to the axis of the accessory.

[0064] In this way, when the accessory is a curling accessory that can curl hair, by making the axis of the blower body coaxial or parallel to the axis of the accessory, compared with the situation in the prior art where the axis of the accessory intersects circumferentially with the blower body, the blower body is further away from the face, avoiding the problem of conflict between the blower body and the face, thereby improving the user experience.

[0065] In a possible implementation, the hair care device also includes a holding portion; the holding portion is rotatably connected to the blower body, and the holding portion can be rotated to a first position relative to the blower body. When the holding portion is rotated to the first position, the axis of the holding portion is coaxial or parallel to the axis of the blower body.

[0066] In this way, when the accessory is a curling accessory that can curl hair, by rotatably connecting the grip portion to the blower body, and making the axis of the grip portion coaxial or parallel with the axis of the blower body when the grip portion is rotated to the first position, the axes of the accessory, the blower body and the grip portion are further coaxial or parallel. Compared with the situation in the prior art where the axis of the grip portion intersects with the axis of the blower body, the grip portion can be further away from the user's face, avoiding the problem of the grip portion contacting the face of the user when the user uses the hair care device, and is more conducive to the user using the hair care device to style the hair, thereby improving the convenience of using the hair care device.

[0067] In a possible implementation, the hair care device also includes a holding portion; the holding portion is rotatably connected to the fan body, and the holding portion can rotate between a first position and a second position relative to the fan body, and when the holding portion is rotated to the first position, the axis of the holding portion is coaxial or parallel to the axis of the fan body; when the holding portion is rotated to the second position, the axis of the holding portion is perpendicular to the axis of the fan body.

[0068] In this way, by enabling the holding portion to rotate between the first position and the second position, the axes of the holding portion, the blower body and the accessory can be coaxial or parallel when the holding portion is rotated to the first position, and the axes of the holding portion and the blower body can be perpendicular when the holding portion is rotated to the second position, so that the hair care device can be held in two forms, thereby improving the convenience of use of the hair care device and enabling the user to choose the holding posture when using the hair care device, thereby improving the user's experience of using the hair care device.

[0069] In a possible implementation, the gripping portion can rotate relative to the fan body in a direction opposite to the air outlet to reach the first position.

[0070] In this way, by rotating the grip in the direction opposite to the air outlet to reach the first position, compared to rotating in the direction toward the air outlet, it is possible to avoid affecting the discharge of airflow at the air outlet when the user rotates the grip toward the first position when the blower body is in operation, and it is possible to avoid mutual interference between the grip and the accessories arranged at the air outlet of the blower body, thereby improving the practicability of the hair care device.

[0071] In a possible implementation, the hair care device also includes a holding portion; the holding portion is rotatably connected to the fan body, and the holding portion can rotate between a first position and a second position relative to the fan body and stay and be relatively fixed at any position; when the holding portion rotates to the first position in a direction away from the air outlet, the axis of the holding portion is coaxial or parallel to the axis of the fan body; when the holding portion rotates to the second position, the axis of the holding portion is perpendicular to the axis of the fan body.

[0072] In this way, the grip portion can stay and be relatively fixed at any position between the first position and the second position relative to the blower body, allowing the user to have more usage angles. For example, the angle between the axial direction of the grip portion and the axis of the blower body can be 145 degrees, so that the user can shape the target object from more angles by rotating the grip portion, further improving the practicability of the hair care device.

[0095] As described in the background technology, when the air outlet direction or use angle of the accessory needs to be adjusted, or when it is frequently pulled by external force during use, the accessory of the hair care device in the prior art cannot be fixed in direction when connected to the fan body, affecting the user's experience. The reason for this problem is that some accessories in the prior art need to adjust the air outlet direction of the accessory, such as the curling accessory for curling hair, and the user can adjust the air outlet direction of the accessory by rotating the adjustment part on the accessory. When the air outlet direction of the curling accessory needs to be adjusted by rotating the structure on the accessory, because the connecting piece between the fan body and the accessory in the prior art can only realize the axial connection between the fan body and the accessory, and does not restrict and fix the relative rotation between the accessory and the fan body, the accessory will shake relative to the fan body or fall off from the fan body, reducing the connection stability between the accessory and the fan body, thereby affecting the user's experience.

[0096] In response to the above technical problems, an embodiment of the present application provides a hair care device, which includes a fan main body, an accessory and a stop mechanism. When the accessory connected to the fan main body used by the user needs to adjust the air outlet direction or the use angle, the first structure and the second structure of the stop mechanism are respectively arranged on the fan main body and the accessory. After the accessory is connected to the fan main body, the direction of the accessory can be fixed relative to the fan main body, thereby preventing the accessory from rotating or moving as a whole relative to the fan main body during the process of adjusting the air outlet direction or the use angle of the accessory, causing the air outlet direction of the accessory to be uncontrollable, and the hair to fly when the user styles or blow-dries. At the same time, the connection stability between the accessory and the fan main body is improved, thereby improving the user's usage experience.

[0097] When the accessories connected to the fan body used by the user do not need to adjust the air outlet direction or the angle of use, or the type of accessories does not change with the change of wind direction, that is, any air outlet direction can achieve the purpose of the accessory, such as an essence air nozzle, an atomization air nozzle, etc., the first structure or the second structure can be set on only one of the fan body and the accessory. In this case, after the fan body and the accessory are connected, the accessory can achieve fixed direction relative to the fan body without the cooperation of the first structure and the second structure.

[0098] To sum up, the hair care device of the present application can flexibly adjust the fixing method between the accessory and the fan body according to the different styling needs of the user, so as to prevent the accessory from rotating or moving relative to the fan body when the user needs to adjust the air outlet direction and usage angle of the accessory, and can achieve that when the user does not need to adjust the air outlet direction and usage angle of the accessory, the connection state between the accessory and the fan body is not constrained, thereby improving the flexibility of the connection between the fan body and the accessory, and can improve the flexibility and practicality of use of the hair care device.

[0099] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0100] refer to Figure 1 , Figure 2 and Figure 3 The embodiment of the present application provides a hair care device, which may include a blower body 100, an accessory 200 and a rotation-stopping mechanism 300. The hair care device may be implemented in the form of a hair dryer as the main body and a styling accessory 200 added thereto, and the hair care device may be hair, wigs or other hair.

[0101] The following specific embodiments are described by taking the hair care device for hair styling as an example.

[0102] Before the accessory 200 is installed on the hair care device, the user can use the blower body 100 to provide cold air or hot air to the hair to dry the hair.

[0103] refer to Figure 1 After the accessory 200 is installed on the fan body 100, the fan body 100 can be used to provide airflow to the accessory 200, and the accessory 200 is used to style the hair through the airflow, wherein the hair styling method is mainly reflected by the structural characteristics and functions of the accessory 200 itself. For example, the accessory 200 with a curling function can perform curling on the hair after being connected to the fan body 100, the anti-flying accessory 200 can perform hair styling to prevent the hair from flying after being connected to the fan body 100, and the smoothing nozzle accessory 200 can perform strong concentrated wind drying on the hair and make the hair smoother after being connected to the fan body 100.

[0104] refer to Figure 2 and Figure 3 The anti-rotation mechanism 300 may include a first structure 310 and / or a second structure 320 , for example, the anti-rotation mechanism 300 may include a first structure 310 and a second structure 320 , or the anti-rotation mechanism 300 may include the first structure 310 or the second structure 320 .

[0105] When the anti-rotation mechanism 300 may include a first structure 310 and a second structure 320, the first structure 310 and the second structure 320 are respectively arranged on the fan body 100 and the accessory 200. For example, the first structure 310 is arranged on the fan body 100, and the second structure 320 is arranged on the accessory 200. After the accessory 200 is connected to the fan body 100, the first structure 310 and the second structure 320 cooperate to fix the accessory 200 relative to the fan body 100.

[0106] It can be understood that the first structure 310 and the second structure 320 cooperate to fix the accessory 200 relative to the fan body 100, which means that when the accessory 200 and the fan body 100 are connected through the first structure 310 and the second structure 320, in the connected state, the accessory 200 and the fan body 100 cannot move relative to each other, for example, along the axis of the fan body 100 (such as Figure 1 Movement in the direction of the central axis P) and rotational movement around the axis of the fan body 100.

[0107] In this way, it can avoid that the accessory 200 as a whole rotates or moves relative to the fan body 100 when the user needs to adjust the air outlet direction or usage angle of the accessory 200, causing the air outlet direction of the accessory 200 to be uncontrollable and the user's hair to fly when styling or drying the hair. At the same time, the connection stability between the accessory 200 and the fan body 100 is improved, thereby improving the user experience.

[0108] When the anti-rotation mechanism 300 may include the first structure 310 or the second structure 320, the first structure 310 or the second structure 320 is disposed on one of the fan body 100 and the accessory 200. After the accessory 200 is connected to the fan body 100, the direction of the accessory 200 may not be fixed relative to the fan body 100. It is understood that the first structure 310 can be disposed on the fan body 100 or the accessory 200, or the second structure 320 can be disposed on the fan body 100 or the accessory 200.

[0109] refer to Figure 2 and Figure 3 In an exemplary embodiment, the first structure 310 can be provided on the fan body 100, and the second structure 320 in the anti-rotation mechanism 300 is not provided on the accessory 200. Therefore, when the accessory 200 connected to the fan body 100 used by the user does not need to adjust the air outlet direction or the use angle, or the type of accessory 200 does not change with the wind direction change, that is, any air outlet direction can achieve the purpose of the accessory 200, such as the essence air nozzle, the atomizing air nozzle, etc., only the first structure 310 or the second structure 320 can be provided on the fan body 100. In this case, after the fan body 100 and the accessory 200 are connected, the accessory 200 can be fixed in direction relative to the fan body 100 without the cooperation of the first structure 310 and the second structure 320. For example, the accessory 200 can rotate relative to the fan body 100.

[0110] To sum up, the hair care device of the present application can flexibly adjust the fixing method between the accessory 200 and the fan body 100 according to the different styling needs of the user, so as to prevent the accessory 200 from rotating or moving relative to the fan body 100 when the user needs to adjust the air outlet direction and the use angle of the accessory 200, or when it is frequently pulled by external force during use. It can also achieve that when the user does not need to adjust the air outlet direction and the use angle of the accessory 200, the connection state between the accessory 200 and the fan body 100 is not constrained, thereby improving the flexibility of the connection between the fan body 100 and the accessory 200, and can improve the flexibility and practicality of the use of the hair care device.

[0111] refer to Figure 1 , Figure 2 and Figure 3The embodiment of the present application also provides a hair care device, which may include a fan body 100, more than two accessories 200 and a rotation-stopping mechanism 300.

[0112] More than two accessories 200 are provided, wherein the accessories 200 are connected to the fan body 100, the fan body 100 is used to provide airflow to the accessories 200, and the accessories 200 are used to shape the target object through the airflow. Any of the accessories 200 can be connected to the fan body 100 alone, and at least two of the accessories 200 have different shaping functions.

[0113] In this way, by using multiple accessories 200 to cooperate with the blower body 100, the user can use different accessories 200 to cooperate with the blower body 100 when styling the hair in different ways, thereby meeting the user's needs for various hair styling functions, enriching the styling function of the hair care device, and improving the practicality of the hair care device.

[0114] The anti-rotation mechanism 300 includes a first structure 310 and at least one second structure 320 . The first structure 310 is disposed on the fan body 100 .

[0115] Some of the accessories 200 are provided with the second structure 320, and the first structure 310 cooperates with the second structure 320 to fix the direction of the accessory 200 provided with the second structure 320 relative to the fan body 100. Some of the accessories 200 are not provided with the second structure 320, so that after the accessory 200 without the second structure 320 is connected to the fan body 100, the direction of the accessory 200 relative to the fan body 100 is not fixed.

[0116] In this way, when the user uses the accessory 200 provided with the second structure 320 to cooperate with the fan body 100, the second structure 320 and the first structure 310 cooperate with each other to achieve the direction of the accessory 200 relative to the fan body 100, thereby reducing the rotation or movement of the accessory 200 provided with the second structure 320 relative to the fan body 100 as a whole, and improving the connection stability between the accessory 200 provided with the second structure 320 and the fan body 100. When the user uses the accessory 200 without the second structure 320 to cooperate with the fan body 100, the accessory 200 can be fixed relative to the fan body 100 without the cooperation of the first structure 310 and the second structure 320, thereby achieving no restriction on the connection state between the accessory 200 and the fan body 100.

[0117] To sum up, the hair care device of the present application can use the accessory 200 with the second structure 320 and the accessory 200 without the second structure 320 to cooperate with the fan body 100 according to the different styling needs of the user, so that the fixing method between the accessory 200 and the fan body 100 can be flexibly adjusted to achieve the situation that when the user needs to adjust the air outlet direction and the use angle of the accessory 200, the accessory 200 is prevented from rotating or moving relative to the fan body 100, and when the user does not need to adjust the air outlet direction and the use angle of the accessory 200, the connection state between the accessory 200 and the fan body 100 is not constrained, thereby improving the flexibility of the connection between the fan body 100 and the accessory 200, and can improve the flexibility and practicality of the use of the hair care device.

[0118] refer to Figure 2 and Figure 3 In some embodiments, the first structure 310 may include at least one groove 311 , and the second structure 320 may include at least one protrusion 321 , and the groove 311 and the protrusion 321 cooperate to fix the accessory 200 relative to the wind turbine body 100 .

[0119] In this way, the shapes of the groove 311 and the protrusion 321 match each other, so that the groove 311 and the protrusion 321 can cooperate with each other in a specific way, thereby achieving precise positioning between the accessory 200 and the fan body 100, so that the accessory 200 and the fan body 100 can be accurately installed during the assembly process.

[0120] The matching mode of the groove 311 and the protrusion 321 can provide a larger contact area and a tighter connection, thereby increasing the stability and load-bearing capacity of the connection between the accessory 200 and the fan body 100. The friction and shape matching between the groove 311 and the protrusion 321 can prevent the accessory 200 and the fan body 100 from loosening or falling off during use.

[0121] The structures of the groove 311 and the protrusion 321 are relatively simple and easy to manufacture and assemble, which can reduce the manufacturing cost of the anti-rotation mechanism 300 and further reduce the manufacturing cost of the hair care device.

[0122] In some embodiments, the groove 311 and the convex portion 321 may be provided in plurality, and the plurality of grooves 311 may be arranged at intervals around the axis of the fan body 100, and the plurality of convex portions 321 may be arranged around the axis of the accessory 200 (eg, Figure 1 The number of the grooves 311 and the number of the protrusions 321 may be the same.

[0123] In some embodiments, the first structure 310 may include at least one first magnetic material, and the second structure 320 may include at least one second magnetic material compatible with the first magnetic material, and the first magnetic material and the second magnetic material cooperate to fix the accessory 200 relative to the wind turbine body 100.

[0124] In this way, the magnetic connection between the first magnetic material and the second magnetic material can realize non-contact connection between the accessory 200 and the fan body 100, and can realize connection between the accessory 200 and the fan body 100 within a certain distance range through the magnetic field or magnetic mutual attraction between the first magnetic material and the second magnetic material without the need for excessive connection operations, thereby improving the connection convenience between the accessory 200 and the fan body 100 and the ease of use of the hair care device.

[0125] Furthermore, the magnetic connection between the first magnetic material and the second magnetic material reduces the wear caused by the contact friction between the first structure 310 and the second structure 320, thereby increasing the service life of the first structure 310 and the second structure 320 and the service life of the hair care device.

[0126] It is understandable that both the first magnetic material and the second magnetic material may be magnetic, or one of the first magnetic material and the second magnetic material may be an iron structural member, so as to achieve the connection between the first magnetic material and the second magnetic material.

[0127] In some embodiments, the first magnetic material is a first magnet, and the second magnetic material is a second magnet or an iron sheet. When the first magnet and the second magnet cooperate, or the first magnet and the iron sheet cooperate, the directions of the accessory 200 and the fan body 100 are relatively fixed. For example, the first magnet can be magnetically connected to the second magnet, or the first magnet can also be connected to the patch.

[0128] In this way, by setting the first magnetic material as the first magnet and the second magnetic material as the second magnet, a non-contact connection can be achieved through the magnetic connection between the first magnet and the second magnet, and the directions of the accessory 200 and the fan body 100 can be relatively fixed. The connection is achieved through the mutual attraction of the magnetic fields between the first magnet and the second magnet, and no excessive connection operations are required, thereby improving the connection convenience between the accessory 200 and the fan body 100 and the convenience of use of the hair care device.

[0129] Furthermore, the magnetic connection between the first magnet and the second magnet reduces the wear caused by the contact friction between the first structure 310 and the second structure 320, thereby increasing the service life of the first structure 310 and the second structure 320 and the service life of the hair care device.

[0130] In addition, the connection method between the first magnet and the iron sheet can realize the connection between the magnet and the metal structure. When the hair care device has an iron component and the iron component can be reused as the second structure 320 of the anti-rotation mechanism 300, the number of parts of the hair care device can be reduced, thereby reducing the manufacturing cost of the hair care device.

[0131] In some embodiments, the first structure 310 is an internal thread, and the second structure 320 is an external thread corresponding to the internal thread. The internal thread and the external thread cooperate to fix the accessory 200 relative to the fan body 100.

[0132] In this way, the accessory 200 and the fan body 100 can be connected and fixed in direction by rotation, and the connection method of internal and external threads can make the connection between the accessory 200 and the fan body 100 withstand greater tension or shear force, thereby improving the connection strength between the accessory 200 and the fan body 100 and the stability of direction fixation.

[0133] The connection between the internal thread and the external thread has a self-locking function, which can prevent the fan body 100 and the accessory 200 from loosening or falling off during use. The inclined surface design of the internal thread and the external thread can generate friction during connection, making the connection more secure.

[0134] In other embodiments, the first structure 310 may further include at least one guide groove, and the second structure 320 may include at least one guide slider matched with the guide groove, and the guide groove and the guide slider cooperate to fix the accessory 200 relative to the direction of the wind turbine body 100.

[0135] In this way, the guide groove and the guide slider can provide a precise guiding connection method, ensuring that the accessory 200 and the fan body 100 can be accurately aligned and positioned when connected.

[0136] In some examples, the first structure 310 may have a plurality of guide grooves, and the second structure 320 may have a plurality of guide sliders, and the number of the guide grooves is the same as the number of the guide sliders. By providing a plurality of guide grooves and a plurality of guide sliders, the alignment accuracy when the accessory 200 and the fan body 100 are connected can be improved.

[0137] In some embodiments, one of the fan body 100 and the accessory 200 is provided with an internal thread, and the other of the fan body 100 and the accessory 200 is provided with an external thread. When the internal thread and the external thread are connected, the directions of the accessory 200 and the fan body 100 are relatively fixed.

[0138] In this way, the connection method of internal thread and external thread can enable the connection between the accessory 200 and the fan body 100 to withstand greater tension or shear force, thereby improving the connection strength between the accessory 200 and the fan body 100 and the stability of directional fixation.

[0139] The connection between the internal thread and the external thread has a self-locking function, which can prevent the fan body 100 and the accessory 200 from loosening or falling off during use. The inclined surface design of the internal thread and the external thread can generate friction during connection, making the connection more secure.

[0140] In some embodiments, a guide groove is provided on one of the fan body 100 and the accessory 200, and a guide slider is provided on the other of the fan body 100 and the accessory 200. The guide groove is provided with a stop portion. The guide slider stops when it slides along the guide groove to the stop portion, and the accessory 200 and the fan body 100 are relatively fixed.

[0141] In this way, by providing a stopper in the guide groove, the displacement range of the guide slider in the guide groove can be limited, preventing the accessory 200 and the fan body 100 from excessive displacement or offset during connection, thereby ensuring that the accessory 200 and the fan body 100 can be accurately aligned and positioned during connection, thereby improving the accuracy of the connection.

[0142] In some embodiments, the specific position of the stop portion in the guide groove can be set according to the connection requirements of the accessory 200 and the fan body 100. For example, when it is necessary to increase the connection stability between the accessory 200 and the fan body 100, the sliding distance of the guide slider in the guide groove can be increased to reduce the probability of the guide slider easily falling out of the guide groove. At this time, the stop portion needs to be set on the side of the guide groove farther from the entrance through which the guide slider slides in, so that the guide slider can penetrate into the guide groove.

[0143] In a possible implementation, the stop portion can be disposed on a side wall of the guide groove, or the stop portion can be disposed on a groove bottom of the guide groove facing away from the guide sliding block.

[0144] refer to Figure 2 and Figure 3 In some embodiments, when there are multiple protrusions 321 and multiple grooves 311 , the number of protrusions 321 is less than or equal to the number of grooves 311 .

[0145] In this way, by making the number of grooves 311 greater than the number of protrusions 321, when the user connects the accessory 200 to the fan body 100, the user can adjust a smaller angle, so that the protrusions 321 and part of the grooves 311 can be aligned and connected, thereby reducing the difficulty of aligning the protrusions 321 and the grooves 311, making it easier for the user to connect and fix the accessory 200 to the fan body 100, thereby improving the ease of use of the hair care device and the user experience.

[0146] It should be noted that the setting of all the above-mentioned anti-rotation mechanisms 300 not only realizes the anti-rotation function, but also can realize the connection between the accessory 200 and the fan body 100, such as the matching of internal and external threads, the matching of magnetic materials, etc. Even if the connection between the accessory 200 and the fan body 100 relies on other connection structures rather than just the above-mentioned anti-rotation mechanism 300, the setting of the anti-rotation mechanism 300 can also increase the connection stability of the accessory 200 to the fan body 100, and reduce the possibility of the accessory 200 falling off from the fan body 100, especially for accessories 200 that are larger in size or are subjected to more external forces during use, such as curling accessories, the setting of the anti-rotation mechanism 300 has a better effect.

[0147] Furthermore, by making the number of icons smaller than the number of grooves 311, the manufacturing process of the hair care device can be simplified and the manufacturing cost of the hair care device can be reduced.

[0148] refer to Figure 2 and Figure 3 In some embodiments, the fan body 100 is provided with an air outlet 110, the groove 311 is opened on the wall near the air outlet 110, the attachment 200 is provided with an air inlet 210, and the convex portion 321 is correspondingly provided on the wall near the air inlet 210 of the attachment 200. When the attachment 200 is connected to the fan body 100, the airflow generated by the fan body 100 can be discharged from the air outlet 110 and further enter the attachment 200 through the air inlet 210 of the attachment 200. The attachment 200 is also provided with an exhaust port for providing airflow for the hair, and the airflow in the attachment 200 can be transported to the hair through the exhaust port for drying and styling the hair.

[0149] In this way, by opening the groove 311 on the wall surface of the air outlet 110 firmware of the fan body 100, and opening the protrusion 321 on the wall surface of the air inlet 210 of the accessory 200, the groove 311 and the protrusion 321 can be matched when the air outlet 110 and the air inlet 210 are connected to each other, thereby improving the connection efficiency between the accessory 200 and the fan body 100.

[0150] refer to Figure 2In some embodiments, the groove 311 extends along the axial direction of the fan body 100, and the notch 3111 of the groove 311 facing the accessory 200 is semicircular or an inwardly concave arc surface, and along the axis perpendicular to the fan body 100, the cross-section of the protrusion 321 is a semicircular or outwardly convex arc surface corresponding to the notch 3111.

[0151] In this way, since the semicircular or arcuate notch 3111 and the convex part 321 with a semicircular or arcuate cross section are easier to achieve accuracy and stability during the manufacturing process, the manufacturing difficulty is relatively low, which can reduce the manufacturing cost and difficulty of the hair care device. In addition, the semicircular notch 3111 and the convex part 321 with a semicircular cross section are less affected by directionality than the polygon, so that the user can more easily achieve the alignment between the groove 311 and the convex part 321, which improves the convenience of using the hair care device.

[0152] In some embodiments, the groove wall of the groove 311 can be a smooth curved surface, and the outer side wall of the protrusion 321 can also be a smooth curved surface that matches the groove wall of the groove 311. By setting the groove wall of the groove 311 and the outer side wall of the protrusion 321 to smooth curved surfaces, the sliding friction between the outer side wall of the protrusion 321 and the inner side wall of the groove 311 can be reduced, thereby facilitating the movement of the protrusion 321 in the groove 311, thereby improving the connection efficiency between the accessory 200 and the fan body 100, and thereby improving the user experience of the hair care device.

[0153] In a possible implementation, the groove 311 may include a first groove segment and a second groove segment that are connected to each other. The first groove segment extends along the axial direction of the fan body 100, one end of the second groove segment is connected to the first groove segment, and the second groove segment extends around the circumference of the fan body 100. During the connection between the accessory 200 and the fan body 100, the protrusion 321 moves along the extension direction of the first groove segment and moves along the extension direction of the second groove segment, so that the accessory 200 and the fan body 100 are relatively fixed in direction.

[0154] In this way, the protrusion 321 is connected to the groove 311 having the first groove segment and the second groove segment, so that when the protrusion 321 is in the first groove segment, the accessory 200 can be fixed in the circumferential direction relative to the fan body 100. When the protrusion 321 is set in the second groove segment, the accessory 200 can be fixed in the axial direction relative to the fan body 100, thereby achieving directional fixation of the accessory 200 and the fan body 100 in at least two directions, thereby improving the connection stability between the accessory 200 and the fan body 100.

[0155] In one possible implementation, on the wall surface of the fan body 100, the groove 311 is arranged along the axial spiral of the fan body 100, and on the wall surface of the fan body 100, the protrusion 321 is arranged along the axial spiral of the fan body 100, and when the protrusion 321 is matched and connected with the groove 311, the direction of the accessory 200 and the fan body 100 is fixed.

[0156] In this way, by rotating the protrusion 321 along the extension direction of the groove 311 in a screwing manner, the groove 311 can limit and fix the protrusion 321 in both the axial direction of the fan body 100 and the axial direction around the fan body 100, so that the accessory 200 and the fan body 100 can be fixed in at least two mutually perpendicular directions, thereby improving the connection stability between the accessory 200 and the fan body 100, and thereby improving the use stability of the hair care device.

[0157] refer to Figure 3 and Figure 4 In some embodiments, the fan body 100 may include an annular member 120. The annular member 120 is disposed in the air outlet 110, and the outer wall of the annular member 120 is spaced apart from the outer shell of the fan body 100, and the outer wall of the annular member 120 is spaced apart from the outer shell of the fan body 100 to form an annular groove 121. The accessory 200 has a flange 220 adapted to the annular groove 121, and when the accessory 200 is connected to the fan body 100, the flange 220 is disposed in the annular groove 121.

[0158] In this way, when the flange 220 is inserted into the annular groove 121, the annular groove 121 can limit the flange 220 in its radial direction, thereby preventing the accessory 200 from being offset or shaking relative to the axial direction of the fan body 100 when connected to the fan body 100, thereby improving the connection stability between the accessory 200 and the fan body 100, and further improving the use stability of the hair care device.

[0159] Furthermore, the design of the annular groove 121 can provide a certain degree of sealing for the connection between the accessory 200 and the fan body 100, preventing external substances such as dust and water vapor from entering the fan body 100 or the accessory 200 through the connection between the accessory 200 and the fan body 100, thereby reducing the probability of damage to the internal components of the fan body 100 and the internal components of the accessory 200, and increasing the service life of the hair care equipment.

[0160] In some embodiments, the interior of the annular member 120 is connected to the air outlet 110 along the axial direction of the fan body 100 , so that the airflow generated by the fan body 100 can be transported to the air inlet 210 of the accessory 200 through the interior of the annular member 120 .

[0161] refer to Figure 2 and Figure 4 In some embodiments, the groove 311 is opened on the outer wall of the annular member 120 , and the protrusion 321 is arranged on the inner wall of the flange 220 .

[0162] In this way, by opening the groove 311 on the outer wall of the annular member 120 or the inner wall of the outer shell of the air outlet 110 of the fan body 100, and correspondingly arranging the protrusion 321 on the inner wall or outer wall of the flange 220, the accessory 200 can be fixed relative to the fan body 100 while the flange 220 is arranged in the annular groove 121, thereby further improving the connection stability between the accessory 200 and the fan body 100.

[0163] In a specific implementation, the groove 311 is opened on the inner wall of the outer shell at the air outlet 110 of the fan body 100 , and the protrusion 321 is arranged on the outer wall of the flange 220 .

[0164] By arranging the groove 311 on the outer side wall of the annular member 120, the integration degree between the various structures on the fan body 100 can be improved. At the same time, by arranging the convex portion 321 on the inner side wall of the flange 220 corresponding to the position of the groove 311, the convex portion 321 and the groove 311 can be located inside the structure, avoiding the convex portion 321 and the groove 311 from being exposed to the outside of the accessory 200 and the fan body 100, thereby improving the aesthetics of the accessory 200 and the fan body 100, and improving the aesthetics of the hair care device and the user experience.

[0165] refer to Figure 2 and Figure 4 In some embodiments, when there are multiple grooves 311 , the multiple grooves 311 are arranged at intervals on the outer wall of the annular member 120 , and when there are multiple protrusions 321 , the multiple protrusions 321 are arranged at intervals on the inner wall of the flange 220 .

[0166] In this way, by spacing and evenly arranging multiple grooves 311 on the outer wall of the annular member 120, and spacing and evenly arranging multiple protrusions 321 on the inner wall of the flange 220, the uniformity of force at the connection between the grooves 311 and the protrusions 321 can be improved, and the uniformity of force when the accessory 200 is connected to the fan body 100 can be improved.

[0167] In a possible implementation, the anti-rotation mechanism 300 may further include at least one clamping member, which is disposed in the groove 311 and is used to clamp the protrusion 321 that cooperates with the groove 311 .

[0168] In this way, by providing a clamping member in the groove 311 to clamp the protrusion 321 located in the groove 311 through the clamping member, the protrusion 321 can be clamped in the groove 311 through the clamping force of the clamping member, thereby further improving the connection stability between the accessory 200 and the fan body 100 and preventing the accessory 200 from shaking or rotating relative to the fan body 100.

[0169] In an exemplary embodiment, the clamping member is an elastic member, which is disposed on the inner wall of the groove 311. When the protrusion 321 is inserted into the groove 311, the elastic member undergoes elastic deformation and fastens the protrusion 321 in the groove 311 through the elastic deformation force.

[0170] In this way, by setting the clamping member as an elastic member, the structure of the clamping member can be simplified, and the manufacturing process and production cost of the clamping member can be simplified, thereby reducing the manufacturing process and manufacturing cost of the hair care device and improving the practicality of the hair care device.

[0172] By providing the first connecting member 410 and the second connecting member 420 , the connection stability between the accessory 200 and the fan body 100 can be further improved.

[0173] In some examples, the first connector 410 and the second connector 420 can both be magnetic connectors, one of which is disposed on the accessory 200 and the other is disposed on the fan body 100, so that the accessory 200 and the fan body 100 are connected via the connection of the two magnetic connectors.

[0175] The accessory 200 includes a second mounting structure 250 , which is disposed in the air inlet 210 , and a second connecting member 420 is disposed on the second mounting structure 250 .

[0176] By arranging the first mounting structure 130 in the annular component 120, the first connecting member 410 can be arranged in the annular component 120, which can improve the compactness between the various components of the fan body 100, improve the space utilization inside the fan body 100, and compared with arranging the first connecting member 410 on the outside of the fan body 100, the appearance of the fan body 100 can be improved.

[0177] Similarly, by arranging the second mounting structure 250 in the air inlet 210 and arranging the second connecting member 420 on the second mounting structure 250, the structural compactness between the components on the accessory 200 can be improved, the utilization rate of the internal space of the accessory 200 can be improved, and the aesthetic appearance of the accessory 200 can be improved, thereby improving the practicality and aesthetics of the hair care device.

[0179] Continue to refer Figure 4 In some examples, a plurality of sub-air outlets 133 are arranged at intervals along the circumference of the bearing portion between the outer peripheral side of the first bearing portion 132 and the inner side wall of the annular member 120. The sub-air outlets 133 are connected to the air outlet 110, and the airflow generated by the fan body 100 can be transported to the accessory 200 through the sub-air outlets 133.

[0180] refer to Figure 2 In some embodiments, the second mounting structure 250 includes a second connecting member 251 and a second bearing portion 252 , and the second bearing portion 252 is connected to the inner wall of the air inlet 210 through the second connecting member 251 .

[0181] A plurality of sub-air inlets 253 are provided between the outer periphery of the second bearing portion 252 and the inner side wall of the air inlet 210. The plurality of sub-air inlets 253 are arranged at intervals along the outer periphery of the second bearing portion 252, and the sub-air inlets 253 are connected to the air inlet 210. There are a plurality of second connecting members 251, which are arranged at intervals along the outer periphery of the second bearing portion 252, and a sub-air inlet 253 is provided between each two adjacent second connecting members 251.

[0182] refer to Figure 2In some embodiments, the accessory 200 may include an adjusting portion 230 and a shaping portion 240. The adjusting portion 230 rotates relative to the shaping portion 240 to adjust the air outlet direction of the shaping portion 240. The shaping portion 240 is used to shape the target object through airflow. The first structure 310 and the second structure 320 are respectively arranged on the fan body 100 and the shaping portion 240. After the shaping portion 240 is connected to the fan body 100 and the adjusting portion 230 rotates relative to the shaping portion 240, the first structure 310 and the second structure 320 cooperate to fix the shaping portion 240 relative to the fan body 100.

[0183] In this way, the user can adjust the air outlet direction of the accessory 200 by adjusting the adjustment part 230, for example, the air outlet direction of the styling part 240 can be adjusted by rotating the adjustment part 230, and when the adjustment part 230 is rotated, since the styling part 240 can be fixed relative to the direction of the fan body 100 through the cooperation of the first structure 310 and the second structure 320, the connection stability between the styling part 240 and the fan body 100 is improved, thereby avoiding the styling part 240 following the rotation of the adjustment part 230 when the user adjusts the air outlet 110 of the styling part 240 through the adjustment part 230, thereby improving the user's experience of using the hair care device.

[0184] In some embodiments, the air inlet 210 can be opened on the side of the styling part 240 facing the fan body 100, and when the second structure 320 in the anti-rotation mechanism 300 can be set on the attachment 200, the second structure 320 can be set on the outer wall or the inner wall of the styling part 240. The interior of the styling part 240 is connected to the air inlet 210, and the styling part 240 is also provided with an exhaust port for conveying airflow to the hair, and the airflow inside the styling part 240 can be conveyed to the hair through the exhaust port.

[0185] Part of the adjustment part 230 is arranged inside the shaping part 240. The user can adjust the air outlet direction and the strength of the airflow of the exhaust port by rotating the adjustment part 230 according to needs so that the part of the adjustment part 230 located inside the shaping part 240 can be adjusted.

[0186] refer to Figure 5 and Figure 6 In some embodiments, the axis of the fan body 100 is coaxial or parallel to the axis of the accessory 200 , for example, the axis of the fan body 100 is coaxial with the axis of the accessory 200 , or the axis of the fan body 100 is parallel to the axis of the accessory 200 .

[0187] In this way, when the accessory 200 is a curling accessory 200 that can curl hair, by making the axis of the fan body 100 coaxial or parallel to the axis of the accessory 200, compared with the situation in the prior art where the axis of the accessory 200 intersects the circumference of the fan body 100, the fan body 100 is further away from the face, avoiding the problem of conflict between the fan body 100 and the face, thereby improving the user experience.

[0188] refer to Figure 5 In some embodiments, the hair care device may further include a grip portion 500. The grip portion 500 is rotatably connected to the fan body 100, and the grip portion 500 can be rotated to a first position relative to the fan body 100. When the grip portion 500 is rotated to the first position, the axis of the grip portion 500 (such as Figure 5 The dotted line N in FIG. 1 is coaxial with or parallel to the axis of the fan body 100.

[0189] In this way, when the accessory 200 is a curling accessory 200 that can curl hair, by rotatably connecting the grip 500 to the fan body 100, and making the axis of the grip 500 coaxial or parallel to the axis of the fan body 100 when the grip 500 is rotated to the first position, the axes of the accessory 200, the fan body 100 and the grip 500 are further coaxial or parallel. Compared with the situation in the prior art where the axis of the grip 500 intersects with the axis of the fan body 100, the grip 500 can be further away from the user's face, thereby avoiding the problem of the grip 500 abutting against the face of the user when the user uses the hair care device, and it is more convenient for the user to use the hair care device to style the hair, thereby improving the convenience of using the hair care device.

[0190] refer to Figure 5 and Figure 6 In other embodiments, the hair care device may further include a grip 500. The grip 500 is rotatably connected to the fan body 100, and the grip 500 can rotate between a first position and a second position relative to the fan body 100. When the grip 500 rotates to the first position, the axis of the grip 500 is coaxial or parallel to the axis of the fan body 100. When the grip 500 rotates to the second position, the axis of the grip 500 is perpendicular to the axis of the fan body 100.

[0191] In this way, by enabling the holding portion 500 to rotate between the first position and the second position, when the holding portion 500 is rotated to the first position, the axes of the holding portion 500, the blower body 100 and the accessory 200 can be coaxial or parallel, and when the holding portion 500 is rotated to the second position, the axes of the holding portion 500 and the blower body 100 can be perpendicular, so that the hair care device can be held in two forms, thereby improving the convenience of use of the hair care device, and enabling the user to choose the holding posture when using the hair care device, thereby improving the user's experience of using the hair care device.

[0192] refer to Figure 5 In some embodiments, the gripping portion 500 can be rotated relative to the fan body 100 in a direction opposite to the air outlet 110 to reach the first position.

[0193] In this way, by rotating the holding portion 500 in the direction opposite to the air outlet 110 to reach the first position, compared to rotating in the direction toward the air outlet 110, it is possible to avoid affecting the discharge of airflow at the air outlet 110 when the user rotates the holding portion 500 toward the first position when the fan body 100 is in operation, and it is possible to avoid mutual interference between the holding portion 500 and the accessory 200 arranged at the air outlet 110 of the fan body 100, thereby improving the practicability of the hair care device.

[0194] refer to Figure 5 and Figure 6 In some embodiments, the hair care device may further include a grip 500. The grip 500 is rotatably connected to the fan body 100. The grip 500 can rotate between a first position and a second position relative to the fan body 100 and stay at any position and be relatively fixed. When the grip 500 rotates to the first position in a direction away from the air outlet 110, the axis of the grip 500 is coaxial or parallel to the axis of the fan body 100. When the grip 500 rotates to the second position, the axis of the grip 500 is perpendicular to the axis of the fan body 100.

[0195] In this way, the holding portion 500 can stay and be relatively fixed at any position between the first position and the second position relative to the blower body 100, allowing the user to have more usage angles. For example, the angle between the axial direction of the holding portion 500 and the axis of the blower body 100 can be 120°, 145° or 160°, so that the user can shape the target object from more angles by rotating the holding portion 500, further improving the practicability of the hair care device.
