[0043] The following is combined with Figures 1-5 The air outlet mechanism and hair dryer according to embodiments of the present invention are described below. In this embodiment, the air outlet mechanism is applied to a hair dryer to adjust the air outlet angle. Of course, in other embodiments, the air outlet mechanism can also be applied to a heater or a fan; that is, any product or device with airflow can utilize the air outlet mechanism described above.

[0044] Understandably, referring to Figures 1 to 5 In this embodiment of the utility model, the air outlet mechanism includes a first component 100 and a second component 200. The second component 200 is disposed on the first component 100, and a ventilation channel 300 is formed between the first component 100 and the second component 200. The first component 100 and the second component 200 can rotate relative to each other to adjust the air outlet angle.

[0045] One of the first component 100 and the second component 200 is provided with a locking unit 110, and the other is provided with a stop part 210. The locking unit 110 is slidable relative to the first component 100 to switch between a locked position and an unlocked position.

[0046] In the locked position, the latching unit 110 contacts the stop 210 to restrict the relative rotation of the first component 100 and the second component 200; in the unlocked position, the latching unit 110 moves away from the stop 210, and the first component 100 and the second component 200 can rotate relative to each other.

[0047] According to the air outlet mechanism of this utility model embodiment, the locking unit 110 and the stop part 210 are in contact and cooperate to lock the first component 100 and the second component 200. When unlocking is required, the user can unlock the device by simply pushing the locking unit 110 up and down. The structure is simple and easy to operate, with high reliability and good stability. It has few parts, which not only makes assembly simple and low cost, but also improves the user experience and overall effect.

[0048] It should be noted that, referring to Figures 1 to 4In this embodiment of the utility model, the first component 100 is provided with a locking unit 110, and the second component 200 is provided with a stop part 210. Of course, in some embodiments, the stop part 210 may also be provided in the first component 100, and the locking unit 110 may also be provided in the second component 200. This is not limited here.

[0049] Understandably, referring to Figures 1 to 4 In this embodiment of the invention, the first component 100 and the second component 200 constitute a spherical structure. Specifically, the preferred shape of the first component 100 and the second component 200 is a hemispherical shell. Of course, in some other embodiments, the first component 100 and the second component 200 may not be hemispherical shells, but rather spherical cap-shaped shells. Therefore, a hemispherical shell is the preferred shape of the first component 100 and the second component 200.

[0050] It should be noted that, referring to Figures 1 to 4 In this embodiment of the utility model, the hair dryer includes a hair dryer handle 600 and an air outlet mechanism, wherein the first component 100 is disposed on the hair dryer handle 600 and connected to the hair dryer handle 600.

[0051] The hair dryer provided according to the embodiments of this utility model includes the above-mentioned air outlet mechanism, and therefore also has the beneficial effects of the above-mentioned air outlet mechanism, which will not be repeated here.

[0052] Specifically, refer to Figures 1 to 4 In this embodiment of the utility model, the connection between the first component 100 and the hair dryer handle 600 can be understood as a fixed connection. In some embodiments, the first component 100 and the hair dryer handle 600 are integrally injection molded. This integral injection molding gives the hair dryer higher structural strength and stability, allowing it to better withstand external forces and vibrations, reducing assembly steps and the number of components, thereby lowering production costs. Alternatively, in other embodiments, the first component 100 and the hair dryer handle 600 are connected by threads or snap-fit ​​connections, which are simple and easy to operate, facilitating disassembly and maintenance. Of course, in some embodiments, the first component 100 and the hair dryer handle 600 can also be movably connected, such as rotatably or slidably, which is not limited here.

[0053] Understandably, referring to Figures 2 to 4 In this embodiment of the utility model, the first component 100 includes a first inner shell 120 and a first outer shell 130 sleeved on the outside of the first inner shell 120. A portion of the structure of the locking unit 110 is slidably connected to the first inner shell 120, and another portion of the structure extends slidably to the outside of the first outer shell 130.

[0054] With the above structure, the first component 100 forms a double-layer structure through the first inner shell 120 and the first outer shell 130. Locking units 110 are arranged on both the first inner shell 120 and the first outer shell 130, which play a relatively reliable limiting role. Furthermore, the first component 100 adopts a double-layer structure, with the inner first shell 120 also serving as heat insulation, while the outer first outer shell 130 does not require heat insulation. The double-layer structure saves the amount of heat insulation material used.

[0055] Of course, in some embodiments, the locking unit 110 may also be disposed only on the first housing 130.

[0056] Understandably, referring to Figures 2 to 4 In this embodiment of the utility model, the second component 200 includes a second inner shell 220 and a second outer shell 230 sleeved on the outside of the second inner shell 220, wherein the stop portion 210 is provided on the second inner shell 220.

[0057] With the above structure, the second component 200 forms a double-layer structure through the second inner shell 220 and the second outer shell 230. The stop 210 is provided in the second inner shell 220, and the second outer shell 230 can protect the stop 210. The second component 200 adopts a double-layer structure. The inner second shell 220 can also play a role in heat insulation, while the outer second outer shell 230 has no heat insulation requirements. The double-layer structure saves the amount of heat insulation material.

[0058] It should be noted that in some embodiments, the second component 200 may be a single-layer shell or a three-layer shell, which is not limited here. It can also be understood that the first component 100 is a single-layer shell and the second component 200 is a double-layer shell, which is not limited here.

[0059] Specifically, refer to Figures 2 to 4 In this embodiment of the invention, the blower handle 600 has an air inlet 610, and the second component 200 is provided with an air outlet 240 that penetrates the second inner shell 220 and the second outer shell 230. One end of the ventilation channel 300 formed by the first component 100 and the second component 200 is the aforementioned air outlet 240, and the other end of the ventilation channel 300 is connected to the air inlet 610. When the second component 200 rotates relative to the first component 100, the air outlet direction can be changed, but the entire spherical rotating structure always maintains its spherical shape, thus maintaining the product's shape. Of course, in some embodiments, the air inlet 610 can also be provided on the first component 100.

[0060] It should be noted that, referring to Figures 2 to 4In this embodiment of the utility model, the spherical surface of the second component 200 is provided with a cut surface, which is inclined to the axis of rotation of the second component 200. The air outlet 240 is located on the cut surface, so that when the second component 200 rotates relative to the first component 100, the air outlet direction can be changed.

[0061] It should be noted that there are multiple stop parts 210. In this embodiment, there are four stop parts 210. Of course, it is not limited to four. There can also be three, five, etc. The locking unit 110 is one. The locking unit 110 contacts and cooperates with one of the four stop parts 210 to lock the first component 100 and the second component 200 after the angle of the air outlet mechanism is adjusted.

[0062] In this embodiment, the four stop portions 210 are spaced apart around the second component 200. The area enclosed by the four stop portions 210 forms a plane, which is inclined to the tangential plane of the air outlet 240 on the second component 200 to form an angle. Therefore, when the second component 200 is rotated, the air outlet angle of the air outlet 240 can be adjusted. Of course, in some embodiments, there may be multiple locking units 110 and one stop portion 210, or multiple locking units 110 and multiple stop portions 210. This is not limited here.

[0063] Specifically, the second component 200 is arranged at an angle of 45 degrees with the axis of rotation of the first component 100 and the axis of the hair dryer handle 600. In this embodiment, after the second component 200 can rotate relative to the first component 100, the hair dryer has three air outlet angles, namely 0° (horizontal air outlet), 45° (tilted air outlet), and 90° (vertical upward air outlet). When air is outleted at these three angles, the first component 100 and the second component 200 can be locked to each other by a locking structure.

[0064] Understandably, referring to Figures 2 to 5 In this embodiment of the utility model, the locking unit 110 is disposed on the first component 100 at the end opposite to the second component 200, and the stop part 210 is disposed on the second component 200 at the end opposite to the first component 100.

[0065] With the above-described configuration, the stop 210 is positioned at one end of the second component 200, opposite to the locking unit 110 of the first component 100. This ensures that the two structures are aligned with each other at a specific location, achieving precise positioning. The design of the stop 210 and the locking unit 110 makes assembly and disassembly between components simple and quick. When maintenance or replacement of components is required, simply opening the locking unit 110 allows the two components to be separated.

[0066] Specifically, refer to Figures 2 to 5In this embodiment of the utility model, the stop part 210 is a locking groove provided in the second component 200. The locking unit 110 includes a sliding plate 111 and a pusher 112. The sliding plate 111 is slidably provided in the first component 100, and the pusher 112 is provided in the sliding plate 111. The pusher 112 can push the sliding plate 111 to slide relative to the first component 100.

[0067] In the unlocked position, the end of the slide plate 111 is inserted into the locking groove to restrict the relative rotation of the first component 100 and the second component 200.

[0068] It should be noted that in this embodiment of the present invention, the first component 100 is provided with a limiting structure 131, which is used to limit the extreme position of the locking unit 110. Specifically, in this embodiment, the limiting structure 131 is a limiting opening on the first outer shell 130 of the first component 100. The upper and lower side walls of the limiting opening limit the extreme position of the push-twist 112 of the locking unit 110, thereby improving the reliability of operation.

[0069] With the above configuration, the limiting structure 131 can prevent the locking unit 110 from exceeding its designed range of motion during operation, thus avoiding damage to the components due to excessive movement. By limiting the extreme positions of the locking unit 110, it can be ensured that the relative positions between the first component 100 and the second component 200 are accurate and consistent each time they are connected, which is especially important for equipment requiring high-precision positioning. Of course, in some embodiments, the limiting structure 131 can also be a limiting boss or a fixed stop block, which restricts the movement of the locking unit 110 when its push knob 112 contacts the limiting boss or the stop block.

[0070] It is understood that in this embodiment of the utility model, the push knob 112 is manually pushed by the user to unlock. Of course, in some embodiments, automatic unlocking can also be achieved by electric means such as electric push rod, motor drive, etc.

[0071] The design employs a locking groove, a sliding plate 111, and a push knob 112. By pushing the push knob 112 up and down, the sliding plate 111 can slide relative to the first component 100. The end of the sliding plate 111 engages with the locking groove. This design effectively restricts the relative rotation between the first component 100 and the second component 200. When the sliding plate 111 is inserted into the groove and fixed, the rotational freedom between the two components is eliminated or significantly reduced, thus maintaining the relative positional stability between the components. The push knob 112 allows the user to control the movement of the sliding plate 111 with a simple pushing action, thereby engaging or disengaging the locking unit 110 from the stop part 210. This operation method is intuitive and easy to master, improving user convenience. The position and status of the push knob 112 visually indicate whether the sliding plate 111 has been correctly inserted into the groove, providing clear visual feedback to the user.

[0072] Of course, in some embodiments, the stop 210 is a protrusion, and the slide plate 111 in the locking unit 110 is provided with a corresponding groove or hole to restrict the relative movement of the first component 100 and the second component 200; or the stop 210 is a hole, and the slide plate 111 of the locking unit 110 is provided with a corresponding protrusion or pin to achieve the same purpose of fixing and preventing rotation. Of course, the stop 210 can also be an embedded component, such as an embedded metal sheet or plastic block, for cooperating with the corresponding part of the locking unit 110. In addition, in some embodiments, the locking unit 110 and the stop 210 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 the magnetic attraction force can be released when the user applies a certain force to push the locking unit 110, which is not limited here.

[0073] It should be noted that, in this embodiment of the utility model, a guide position is provided on the first inner shell 120 of the first component 100 to cooperate with the slide plate 111. The guide position can be set as a guide groove or a guide rail to limit the sliding direction of the slide plate 111 to be fixed, thereby improving the reliability and accuracy of locking; and the width of the corresponding limiting opening on the slide plate 111 is greater than the width of the limiting opening to prevent the slide plate 111 from detaching from the first outer shell 130.

[0074] Specifically, refer to Figures 2 to 5 In this embodiment of the utility model, the slide plate 111 and the push knob 112 are detachably connected.

[0075] With the above structure, since the slide plate 111 and the push knob 112 can be disassembled independently, it is not necessary to disassemble the entire structure when maintaining or replacing one of the components, thus saving time and labor. Disassembling the slide plate 111 and the push knob 112 makes cleaning and inspection easier, ensuring the cleanliness and proper functioning of the connecting parts and extending their service life.

[0076] Specifically, refer to Figures 2 to 5 In this embodiment of the utility model, the slide plate 111 is provided with a first locking structure 400, and the push knob 112 is provided with a second locking structure 500 on the side facing the slide plate 111. The second locking structure 500 engages with the first locking structure 400 to prevent the push knob 112 from disengaging from the slide plate 111.

[0077] Through the above structure, the snap-fit ​​between the second snap-fit ​​structure 500 and the first snap-fit ​​structure 400 can effectively fix the position of the push knob 112 on the slide plate 111, preventing the push knob 112 from accidentally detaching from the slide plate 111 during the up-and-down pushing operation. The snap-fit ​​design makes the installation and removal of the push knob 112 simple and quick, without the need for additional tools, thus simplifying the assembly process.

[0078] Specifically, refer to Figures 2 to 5 In this embodiment of the utility model, the first snap-fit ​​structure 400 includes two snap-fit ​​through holes 410, and the second snap-fit ​​structure 500 includes two elastic arms 510 arranged in opposite directions. The ends of the two elastic arms 510 away from the push knob 112 are provided with snap-fit ​​protrusions 511. The elastic arms 510 are inserted into the snap-fit ​​through holes 410, and the snap-fit ​​protrusions 511 abut against the inner sidewall of the slide plate 111.

[0079] Through the above structure, the two elastic arms 510 are respectively inserted into the two snap-fit ​​holes 410, forming a double fixing point, which increases the stability of the connection between the push knob 112 and the slide plate 111. The snap-fit ​​protrusion 511 abuts against the inner sidewall of the slide plate 111, effectively preventing the elastic arms 510 from accidentally falling out of the snap-fit ​​holes, ensuring that the push knob 112 remains in the correct position during operation. The design of the elastic arms 510 restricts the direction of movement of the push knob 112, preventing the push knob 112 from moving in an unexpected direction, maintaining the accuracy and consistency of operation. The second snap-fit ​​structure 500 can provide a certain buffering effect, reducing component wear caused by impact or vibration, increasing the durability of the overall structure, and the second snap-fit ​​structure 500 may provide a certain resistance or audible feedback when the push knob 112 is pushed, giving the user a clear signal that the push knob 112 has been correctly engaged with the slide plate 111.

[0080] The design of the elastic arm 510 allows the push-twist 112 to be assembled and disassembled by simple insertion and removal actions without the use of additional tools. Specifically, during the removal process, the two back-to-back elastic arms 510 are pressed together and brought closer to each other, thereby engaging the protrusion 511 away from the inner wall of the slide plate 111, so that the elastic arm 510 is disengaged from the slide plate 111 along the engaging through hole 410.

[0081] Of course, in some embodiments, the push knob 112 and the slide plate 111 may also be provided with threaded holes and threaded posts respectively, and can be connected and disassembled by rotating the threads; or, the push knob 112 and the slide plate 111 may be configured as an integral injection molding, etc., which are not limited here.

[0082] Understandably, referring to Figures 2 to 5 In this embodiment of the utility model, the locking unit 110 further includes an elastic element 113, which is disposed between the slide plate 111 and the first component 100. The elastic element 113 is used to drive the slide plate 111 to reset to the locked position.

[0083] When the end of the slide plate 111 is inserted into or removed from the locking groove, the elastic element 113 deforms, providing a restoring force. This design ensures that after the end of the slide plate 111 is removed, the elastic element 113 can push it back to its original position, maintaining structural stability. Furthermore, the presence of the elastic element 113 reduces hard collisions and wear between components, extending the product's lifespan. This 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 element 113, making the product more reliable and user-friendly.

[0084] Specifically, refer to Figures 2 to 5 In this embodiment of the utility model, a positioning protrusion is provided at the other end of the slide plate 111 away from the locking groove. The elastic element 113 is a spring and is sleeved on the positioning protrusion. Through the above structure, the positioning protrusion can ensure that the elastic element 113 is accurately aligned in a specific position, reduce assembly errors, and improve the precision of the product.

[0085] It should be noted that in some embodiments, the elastic element 113 may also be an elastic sheet or an elastic pad, etc., which is not limited here.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model and should be covered within the protection scope of the present utility model.
