In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0035] Combine the following Figure 1-Figure 9 A hair dryer according to an embodiment of the present invention is described.

[0036] Reference Figures 1 to 4 According to an embodiment of the present invention, the hair dryer includes a hair dryer handle 100 and an air outlet mechanism, the air outlet mechanism includes a first air outlet component 200 and a second air outlet component 300, the first air outlet component 200 is connected to the hair dryer handle 100, and the second air outlet component 300 is rotatably connected to the first air outlet component 200; an air duct 400 is formed between the first air outlet component 200 and the second air outlet component 300, and an air outlet 341 connected to the air duct 400 is provided on the second air outlet component 300, the first air outlet component 200 and the second air outlet component 300 form a spherical structure, and the second air outlet component 300 can adjust the air outlet angle of the air outlet mechanism when it rotates relative to the first air outlet component 200.

[0037] According to the hair dryer of the embodiment of the present invention, since the first air outlet component 200 and the second air outlet component 300 form a spherical structure, when the second air outlet component 300 rotates relative to the first air outlet component 200, the shape of the air outlet mechanism remains unchanged, and the air duct 400 formed between the first air outlet component 200 and the second air outlet component 300 has little difference before and after rotation, and the air duct 400 is smooth and has stable performance.

[0038] More specifically, when the second air outlet component 300 rotates relative to the first air outlet component 200, the interior of the spherical structure formed by the first air outlet component 200 and the second air outlet component 300 can always maintain a roughly spherical spatial form, and when the airflow enters the interior of the spherical structure from the air inlet 210, it can flow along the inner wall of the spherical structure to the air outlet 341. In this way, even if the air outlet angle is adjusted, the shape of the air duct 400 always remains smooth without sharp bends; and the shape of the air duct 400 changes little before and after the air outlet angle changes. Compared with the products in the related art in which the shape of the air duct 400 is sharply bent or greatly changed when the air outlet angle is changed, the spherical structure formed by the first air outlet component 200 and the second air outlet component 300 in this embodiment has a significant improvement effect on reducing product noise and stabilizing wind speed.

[0039] It can be understood that in the embodiment of the present invention, a locking structure is provided between the first air outlet component 200 and the second air outlet component 300, and the locking structure is used to lock the relative positions of the first air outlet component 200 and the second air outlet component 300, which is beneficial to prevent the second air outlet component 300 from shifting when blowing hair at different angles, thereby ensuring the user's blowing experience.

[0040] It should be noted that, in the embodiment of the present invention, the shapes of the first air outlet component 200 and the second air outlet component 300 are configured as a hemispherical structure. Specifically, the preferred shape of the first air outlet component 200 and the second air outlet component 300 is a hemispherical shell. Of course, in other embodiments, in some cases, the first air outlet component 200 and the second air outlet component 300 may not be a hemispherical shell, but a shell in the shape of a spherical segment. Therefore, the hemispherical shell is the preferred shape of the first air outlet component 200 and the second air outlet component 300.

[0041] Specifically, refer to Figures 1 to 3 In the embodiment of the present invention, the hair dryer handle 100 has an air inlet 210, one end of the air duct 400 formed by the first air outlet component 200 and the second air outlet component 300 is connected to the above-mentioned air outlet 341, and the other end of the air duct 400 is connected to the air inlet 210; when the second air outlet component 300 rotates relative to the first air outlet component 200, the air outlet direction can be changed, but the entire spherical rotating structure always maintains a spherical shape, which can maintain the shape of the product unchanged. Of course, in some embodiments, the air inlet 210 can also be set on the first air outlet component 200.

[0042] It should be noted that, refer to Figure 3 In the embodiment of the present invention, the second air outlet component 300 rotates around the first axis B relative to the first air outlet component 200, the blowing handle 100 has a second axis C in the left and right direction, and the first axis B is inclined to the second axis C.

[0043] With the above settings, the tilted setting allows users to adjust the wind direction more conveniently, so that the wind can blow to the target area more accurately instead of blowing directly; in addition, the tilted design also helps to improve airflow distribution, reduce wind resistance changes, and make the blowing performance more stable; and it may be more visually attractive, increasing the appearance design sense of the hair dryer product.

[0044] Reference Figure 3 In the embodiment of the present invention, the angle between the first axis B and the second axis C is 40° to 50°. Specifically, in the present embodiment, the angle between the first axis B and the second axis C is 45°.

[0045] In the embodiment of the present invention, when the second air outlet component 300 rotates relative to the first air outlet component 200, the hair dryer has three air outlet angles: Figure 1 , when the air outlet angle is 0°, the air outlet is horizontal; refer to Figure 5 , when the air outlet angle is 45°, it is tilted; refer to Figure 6 , the air outlet angle is 90°, that is, the air is discharged vertically upward. When the air is discharged at these three angles, the first air outlet component 200 and the second air outlet component 300 can be locked to each other using a locking structure.

[0046] It should be noted that, in the embodiment of the present invention, the second air outlet component 300 can be rotated to any angle, there is no angle restriction during use, and the use angle does not need to be locked.

[0047] It can be understood that, in the embodiment of the present invention, the first air outlet component 200 is connected to the hair dryer handle 100, which can be understood as the first air outlet component 200 and the hair dryer handle 100 can be fixedly connected. In some embodiments, the first air outlet component 200 and the hair dryer handle 100 are integrally injection molded. The integral injection molding enables the hair dryer to have higher structural strength and stability, and can better withstand external forces and vibrations, reducing the number of assembly steps and parts, thereby reducing production costs; or, in other embodiments, the first air outlet component 200 and the hair dryer handle 100 are threadedly connected or snap-fitted, and the connection method is simple and easy to operate, and is convenient for disassembly and maintenance. Of course, in some embodiments, the first air outlet component 200 and the hair dryer handle 100 can also be movably set, such as rotatably connected or slidably connected, which is not limited here.

[0048] It is understood that in the embodiment of the present invention, the ratio of the outer diameter of the spherical structure formed by the air outlet mechanism to the length of the hair dryer handle 100 is 0.35 to 0.45. In this embodiment, the ratio of the outer diameter of the spherical structure formed by the air outlet mechanism to the length of the hair dryer handle 100 is 0.4.

[0049] It can be understood that the length of the hair dryer handle 100 and the outer diameter of the spherical structure formed by the air outlet mechanism are within a certain proportional range. Therefore, small-sized components are used in the hair dryer handle 100. For example, the power can be lower if the motor size is reduced. However, since the air outlet mechanism is shorter, low power can still maintain a high wind speed.

[0050] Specifically, refer to Figure 3 , Figure 7 and Figure 8 In the embodiment of the present invention, the first air outlet component 200 includes a first inner shell 220 and a first outer shell 230 sleeved on the outside of the first inner shell 220, and the second air outlet component 300 includes a second inner shell 320 and a second outer shell 330 sleeved on the outside of the second inner shell 320.

[0051] With the above structure, the first air outlet component 200 and the second air outlet component 300 are both double-sided shell structures, the inner shell can play a heat insulation role, while the outer shell has no heat insulation requirements, and the setting of the inner and outer double-layer structure saves the amount of heat insulation material.

[0052] It should also be noted that in some embodiments of the present invention, when the first air outlet component 200 adopts a double-layer shell structure, the space between the first inner shell 220 and the first outer shell 230 can be used to install device structures such as a plasma generator, making full use of the product space and having a compact structure.

[0053] Of course, in some embodiments, the first air outlet component 200 and the second air outlet component 300 may also be a single shell, or three shells, which is not limited here.

[0054] It should be noted that, in some embodiments, the first air outlet component 200 and the second air outlet component 300 may also be a single-layer shell, or a three-layer shell, which is not limited here. It can also be understood that the first air outlet component 200 is a single-layer shell, and the second air outlet component 300 is a double-layer shell, which is not limited here.

[0055] It is understandable that, referring to Figure 3 and Figure 8 In the embodiment of the present invention, the spherical surface of the second air outlet component 300 is provided with a section, and the section is inclined between the section and the first axis B of the second air outlet component 300. An air outlet cover 340 is provided on the section, and the air outlet cover 340 is connected to the second inner shell 320. The air outlet cover 340 is provided with an air outlet 341, so that when the second air outlet component 300 rotates relative to the first air outlet component 200, the air outlet direction can be changed.

[0056] Reference Figure 1 , Figure 3 and Fig. 9In the embodiment of the present invention, a connecting structure 342 is provided at the air outlet 341 of the second air outlet component 300 , and the connecting structure 342 is used to be detachably connected to the hairdressing attachment 700 .

[0057] Through the above arrangement, a hairdressing accessory 700 such as a curling iron, a straight comb or a fluffing comb can be detachably connected to the second air outlet component 300, so that the hairdressing accessory 700 can be rotated to an angle that is convenient for operation by rotating the second air outlet component 300.

[0058] In this embodiment, the connection structure 342 is a snap-in protrusion provided on the air outlet cover 340, and the hairdressing accessory 700 is correspondingly provided with a snap-in groove. The snap-in protrusion and the snap-in groove are snap-fitted to make the hairdressing accessory 700 detachably connected to the second air outlet component 300.

[0059] Of course, the detachable connection between the hairdressing accessory 700 and the second air outlet component 300 can also be in the following ways: fixing the hairdressing accessory 700 on the second air outlet component 300 by a threaded knob or a bolt, which can be conveniently tightened or loosened; or fixing the hairdressing accessory 700 on the second air outlet component 300 by a clamp, which is usually installed and removed by pressing or sliding; or adsorbing the hairdressing accessory 700 on the second air outlet component 300 by using a magnetic material, and only the magnetic attraction needs to be removed for removal.

[0060] It is understandable that, referring to Figure 3 , Figure 4 , Figure 7 and Figure 8 In the embodiment of the present invention, a sealing structure 800 for sealing the matching gap between the first air outlet component 200 and the second air outlet component 300 is provided, which is helpful to prevent leakage of the medium (such as hot air).

[0061] Specifically, refer to Figure 4 and Figure 8 In an embodiment of the present invention, the sealing structure 800 includes a sealing protrusion 810, a sealing groove 820 and a sealing ring 830. One of the sealing protrusion 810 and the sealing groove 820 is arranged on the first air outlet component 200, and the other is arranged on the second air outlet component 300. The sealing groove 820 is snap-fitted with the sealing protrusion 810 and can rotate relative to each other. The sealing ring 830 is arranged in the sealing groove 820 and is clamped between the sealing groove 820 and the sealing protrusion 810.

[0062] In an embodiment of the present invention, the above-mentioned sealing protrusion 810 is arranged on the first inner shell 220 of the first air outlet component 200, and the sealing groove 820 is arranged on the second inner shell 320 of the second air outlet component 300. Of course, in some embodiments, the sealing protrusion 810 can also be arranged on the second air outlet component 300, and the sealing groove 820 can also be arranged on the first air outlet component 200, which is not limited here.

[0063] It is understandable that the cooperation of the sealing protrusion 810 and the groove forms a series of tortuous channels. When the airflow flows through the sealing structure 800, it needs to change direction several times before passing through, forming a labyrinth seal, so it can effectively prevent the passage of fluid or gas, which is conducive to preventing the leakage of the medium (such as hot air). The existence of the sealing ring 830 further enhances the sealing effect, because it can fill any tiny gap to prevent the leakage of hot air; because the sealing groove 820 and the sealing protrusion 810 can rotate relative to each other, it is suitable for the first air outlet component 200 and the second air outlet component 300 that rotate relative to each other, and can allow a certain relative movement while maintaining the seal; the sealing structure 800 reduces wear by reducing the direct contact area, and the sealing ring 830 is usually made of wear-resistant material, which further extends the service life of the sealing structure 800; the sealing ring 830 is sandwiched between the sealing groove 820 and the protrusion, and if it needs to be replaced, it can be carried out relatively easily.

[0064] In addition to the above, in this embodiment, the first air outlet component 200 and the second air outlet component 300 are also snap-fitted by the sealing protrusion 810 and the sealing groove 820 to achieve a detachable connection between the two. The above design meets the requirements of sealing and connection at the same time, reduces the number of components and the complexity of the design, and the sealing structure 800 itself has high reliability. With the snap-fit ​​connection, the stability of the overall structure is further enhanced. Since the above design integrates the sealing and connection functions, it is beneficial to reduce the need for additional fasteners and seals, thereby reducing costs.

[0065] In some embodiments, the sealing structure 800 can also be configured as a sawtooth labyrinth seal, the tooth shape of which is similar to a sawtooth, which can provide a more complex flow path and increase leakage resistance.

[0066] It is understandable that, referring to Figures 2 to 4 ,as well as Figure 7 and Figure 8 In the embodiment of the present invention, the locking structure includes a stopper 310 and a locking unit 210. One of the second air outlet component 300 and the first air outlet component 200 is provided with the stopper 310, and the other is slidably provided with the locking unit 210. The locking unit 210 has a locking position and an unlocking position. In the locked position, the locking unit 210 contacts the stopper 310 to limit the relative rotation of the second air outlet component 300 and the first air outlet component 200; in the unlocked position, the locking unit 210 is away from the stopper 310, and the second air outlet component 300 and the first air outlet component 200 are relatively rotatable.

[0067] The first air outlet component 200 and the second air outlet component 300 are locked by the contact and cooperation between the locking unit 210 and the stop portion 310; when unlocking is required, the user can unlock the air outlet component 200 by simply pushing the locking unit 210 up and down to slide. The structure is simple and easy to operate, with high reliability, good stability and few parts. It is not only simple to assemble and low in cost, but also improves the user experience and overall effect.

[0068] It should be noted that, refer to Figures 2 to 4 ,as well as Figure 7 and Figure 8 In the embodiment of the present invention, the first air outlet component 200 is slidably provided with a locking unit 210, and the second air outlet component 300 is provided with a stopping portion 310. Of course, in some embodiments, the above-mentioned stopping portion 310 can also be provided on the first air outlet component 200, and the locking unit 210 can also be provided on the second air outlet component 300, which is not limited here.

[0069] It should be noted that there are multiple stop parts 310. In the present embodiment, there are four stop parts 310, but it is certainly not limited to four and may also be three, five, etc. There is one locking unit 210, and the locking unit 210 is in contact with and cooperates with one of the four stop parts 310 to lock the first air outlet component 200 and the second air outlet component 300 after adjusting the angle of the air outlet mechanism.

[0070] In this embodiment, the four stoppers 310 are arranged at intervals around the second air outlet component 300, and the area enclosed by the four stoppers 310 forms a plane, which is inclined to the tangent plane where the air outlet 341 on the second air outlet component 300 is located to form an angle, so when the second air outlet component 300 is rotated, the air outlet angle of the air outlet 341 can be adjusted. Of course, in some embodiments, the locking unit 210 can also be multiple, the stopper 310 is one, or both the locking unit 210 and the stopper 310 are set to multiple, which is not limited here.

[0071] In the embodiment of the present invention, the locking unit 210 is disposed on an end of the first air outlet component 200 opposite to the second air outlet component 300 , and the stopper 310 is disposed on an end of the second air outlet component 300 opposite to the first air outlet component 200 .

[0072] Through the above arrangement, the stopper 310 is arranged at one end of the second air outlet component 300, opposite to the locking unit 210 of the first air outlet component 200, so that the two structures can be aligned with each other at a specific position to achieve accurate positioning. Through the design of the stopper 310 and the locking unit 210, the assembly and disassembly between the components can be made simple and quick. When maintenance or replacement of components is required, the two components can be separated by simply opening the locking unit 210.

[0073] Specifically, refer to Figures 2 to 4 ,as well as Figure 7 and Figure 8 In the embodiment of the present invention, the stopper 310 is a locking groove provided on the second air outlet component 300, and the locking unit 210 includes a slide plate 211 and a push-twist 212, the slide plate 211 is slidably provided on the first air outlet component 200, and the push-twist 212 is provided on the slide plate 211, and the push-twist 212 can push the slide plate 211 to slide relative to the first air outlet component 200; In the unlocking position, the end of the slide plate 211 is inserted into and matched with the locking groove to limit the relative rotation of the first air outlet component 200 and the second air outlet component 300.

[0074] It should be noted that, refer to Figures 2 to 4 In the embodiment of the present invention, the first air outlet component 200 is provided with a limiting structure 231, and the limiting structure 231 is used to limit the limit position of the movement of the lock unit 210. Specifically, in this embodiment, the limiting structure 231 is a limiting opening opened on the first housing 230 of the first air outlet component 200, and the upper and lower side walls of the limiting opening limit the upper and lower push-up limit positions of the push knob 212 of the lock unit 210, thereby improving the reliability of the operation.

[0075] With the above arrangement, the limiting structure 231 can prevent the locking unit 210 from exceeding its designed range of motion during operation, thereby avoiding damage to the components due to excessive motion. By limiting the extreme position of the locking unit 210, it can be ensured that the relative position between the first air outlet component 200 and the second air outlet component 300 is accurate and consistent each time they are connected, which is particularly important for equipment that requires high-precision positioning. Of course, in some embodiments, the limiting structure 231 can also be set as a limiting boss, or a fixed stop block, and when the push-twist 212 of the locking unit 210 contacts the limiting boss or the stop block, its movement is limited.

[0076] It is understandable that in the embodiment of the present invention, the push knob 212 is manually pushed by the user to achieve unlocking. Of course, in some embodiments, automatic unlocking can also be achieved through electric means such as an electric push rod, motor transmission, etc.

[0077] The design of the locking groove, the slide plate 211 and the push knob 212 is adopted, and the slide plate 211 can slide relative to the first air outlet component 200 by pushing the push knob 212 up and down, and the end of the slide plate 211 is inserted into the locking groove and matched, and the above design can effectively limit the relative rotation between the first air outlet component 200 and the second air outlet component 300. When the slide plate 211 is inserted into the groove and fixed, the rotational freedom between the two components is eliminated or greatly reduced, thereby maintaining the relative position between the components stable. The setting of the push knob 212 allows the user to control the movement of the slide plate 211 through a simple pushing action, thereby realizing the combination or separation of the locking unit 210 and the stopper 310. This operation method is intuitive and easy to master, which improves the user's operational convenience. The position and state of the push knob 212 can intuitively indicate whether the slide plate 211 has been correctly inserted into the groove, providing the user with clear visual feedback.

[0078] Of course, in some embodiments, the stopper 310 is set as a protrusion, and the slide plate 211 in the lock unit 210 is provided with a corresponding groove or hole to limit the relative movement of the first air outlet component 200 and the second air outlet component 300; or the stopper 310 is set as a hole, and the slide plate 211 of the lock unit 210 is provided with a corresponding protrusion or pin to cooperate, so as to achieve the purpose of fixing and rotating. Of course, the stopper 310 can also be an embedded component, such as an embedded metal sheet or plastic block, which is used to cooperate with the corresponding part of the lock unit 210. In addition, in some embodiments, the lock unit 210 and the stopper 310 can also use the attraction between magnetic materials to fix the two components. Of course, the magnetic attraction force is greater than the wind force, and when the user applies a certain force to push the lock unit 210, the magnetic attraction force can be released; or, in some embodiments, the lock structure can also be a gear ring structure, which is not limited here.

[0079] It should be noted that, in the embodiment of the present invention, a guide position cooperating with the slide plate 211 is provided on the first inner shell 220 of the first air outlet component 200, and the guide position can be set as a guide groove or a guide rail to limit the sliding direction of the slide plate 211 to be fixed, thereby improving the reliability and accuracy of the locking; and the width of the slide plate 211 is greater than the width of the limiting opening to prevent the slide plate 211 from detaching from the first outer shell 230.

[0080] Specifically, refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 In the embodiment of the present invention, the slide plate 211 and the push knob 212 are detachably connected.

[0081] With the above structure, since the slide plate 211 and the push knob 212 can be disassembled independently, when maintaining or replacing one of the components, it is not necessary to disassemble the entire structure as a whole, thereby saving time and labor. Disassembling the slide plate 211 and the push knob 212 can make it easier to clean and inspect, ensuring that the connection components are clean and work properly, and extending the service life.

[0082] Specifically, refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 In an embodiment of the present invention, the slide plate 211 is provided with a first clamping structure 500, and a second clamping structure 600 is provided on the side of the push knob 212 facing the slide plate 211. The second clamping structure 600 is engaged with the first clamping structure 500 to limit the push knob 212 from separating from the slide plate 211.

[0083] Through the above structure, the second clamping structure 600 and the first clamping structure 500 can effectively fix the position of the push knob 212 on the slide 211, preventing the push knob 212 from accidentally detaching from the slide 211 during the operation of pushing up and down. The clamping design makes the installation and removal process of the push knob 212 simple and quick, without the need for additional tools, and simplifies the assembly process.

[0084] Specifically, refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 In an embodiment of the present invention, the first clamping structure 500 includes two clamping through holes 510, and the second clamping structure 600 includes two elastic arms 610 arranged back to back. The two elastic arms 610 are provided with a clamping protrusion 611 at one end away from the push button 212. The elastic arm 610 is inserted into the clamping through hole 510, and the clamping protrusion 611 abuts against the inner wall of the slide plate 211.

[0085] Through the above structure, the two elastic arms 610 are respectively inserted into the two snap-in holes 510 to form a double fixing point, which increases the stability of the connection between the push-twist 212 and the slide 211. The snap-in protrusion 611 abuts against the inner wall of the slide 211, effectively preventing the elastic arm 610 from accidentally falling off from the snap-in hole, and ensuring that the push-twist 212 remains in the correct position during operation. The design of the elastic arm 610 limits the moving direction of the push-twist 212, preventing the push-twist 212 from moving in an unexpected direction, and maintaining the accuracy and consistency of the operation. The second snap-in structure 600 can provide a certain buffering effect, reduce the wear of components caused by impact or vibration, and increase the durability of the overall structure. The second snap-in structure 600 may provide a certain resistance or sound feedback when the push-twist 212 is pushed, giving the user a clear signal that the push-twist 212 has been correctly matched with the slide 211.

[0086] The design of the elastic arm 610 allows the push-twist 212 to be assembled and disassembled by simple insertion and extraction actions without the use of additional tools. Specifically, during the extraction process, the two elastic arms 610 arranged in back to back directions are pressed toward each other and brought closer together, so that the engaging protrusion 611 is moved away from the inner side wall of the slide plate 211 along the engaging through hole 510, so that the elastic arm 610 is separated from the slide plate 211 along the engaging through hole 510.

[0087] Of course, in some embodiments, the push knob 212 and the slide plate 211 may also be provided with threaded holes and threaded columns respectively, and connected and disassembled by threaded rotation; or, the push knob 212 and the slide plate 211 may be configured as an integral injection molding, etc., which is not limited here.

[0088] It is understandable that, referring to Figure 3 , Figure 4 , Figure 7 and Figure 8 In the embodiment of the present invention, the locking unit 210 further includes an elastic member 213, which is disposed between the slide plate 211 and the first air outlet component 200, and is used to drive the slide plate 211 to return to the locking position.

[0089] When the end of the slide plate 211 is inserted into or pulled out of the locking groove, the elastic member 213 will be deformed to provide a reset force. The above design ensures that after the end of the slide plate 211 is removed, the elastic member 213 can push it back to its original position to maintain the stability of the structure. In addition, due to the presence of the elastic member 213, the hard collision and wear between the components are reduced, and the service life of the product is extended. The above structural design not only improves the stability and durability of the hair dryer components, but also enhances the user experience through the use of the elastic member 213, making the product more reliable and user-friendly.

[0090] Specifically, refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 In the embodiment of the present invention, a positioning boss is provided on the other end of the slide plate 211 away from the locking groove, and the elastic member 213 is a spring. The elastic member 213 is sleeved on the positioning boss. Through the above structure, the positioning boss can ensure that the elastic member 213 is accurately aligned at a specific position, reduce assembly errors, and improve product accuracy.

[0091] It should be noted that, in some embodiments, the elastic member 213 may also be an elastic sheet or an elastic pad, etc., which is not limited here.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be included in the protection scope of the present invention.
