Description

Technical Field

[0001] The utility model relates to the field of hair dryers, and particularly to a hair dryer that is convenient to use. Background Art

[0002] For existing hair dryers, in products equipped with a swinging nozzle, by adjusting the swing of the swinging nozzle, the air flow direction can be changed, which can solve the problem of excessive local temperature caused by concentrated hot air. There are two scenarios when using, namely the swinging and non-swinging of the swinging nozzle, and users can switch the state of the swinging nozzle according to their needs.

[0003] For example, the existing patent CN110680071A discloses a nozzle structure of a hair dryer, in which locking parts that cooperate with each other are respectively provided on the inner nozzle and the outer nozzle. Through the relative movement of the outer nozzle and the inner nozzle, the inner nozzle can be switched between the swinging state and the locking state. This existing technology requires users to push and pull the outer nozzle to achieve the switching of the inner nozzle state. On the one hand, it relies on both hands to operate, reducing convenience. On the other hand, when the hair dryer is working in the hot air mode, there is a risk of being scalded by hot air when operating the outer nozzle. Summary of the Utility Model

[0004] In order to solve the technical problems in the existing technology that unlocking and locking the inner nozzle by pushing and pulling the outer nozzle are inconvenient to operate and prone to being scalded by hot air, the utility model provides a hair dryer that is convenient to use, aiming to simplify the operation of switching the state of the inner nozzle. Users can operate by pressing a button with one hand, which is convenient to use and can prevent being scalded by hot air when operating the outer nozzle.

[0005] A hair dryer that is convenient to use disclosed by the utility model includes a hair dryer main body and a nozzle assembly installed at the air outlet end of the hair dryer main body. The nozzle assembly includes an outer nozzle and an inner nozzle rotatably installed in the outer nozzle. The outer nozzle is provided with a braking member arranged to slide. The outer nozzle locks the inner nozzle through the braking member. The hair dryer main body is provided with a driving mechanism. The driving mechanism includes a button, a push rod and a transmission member. One end of the transmission member is in transmission connection with the push rod, and the other end is in transmission connection with the button. The transmission member is arranged such that when the button is pressed, the push rod is pushed to slide to abut against the braking member to slide for unlocking or locking the inner nozzle.

[0006] The hair dryer that is convenient to use of the utility model further has the following additional technical features:

[0007] The transmission member is a transmission lever rotatably arranged on the hair dryer main body. One end of the transmission lever abuts against the push rod, and the other end abuts against the button. Pressing the button can push the transmission lever to swing, so that the transmission lever pushes the push rod to slide to abut against the braking member to slide for unlocking or locking the inner nozzle.

[0008] The inner air nozzle is provided with a brake pad. One end of the brake member away from the ejector rod is provided with a brake groove. One end of the brake groove away from the air outlet of the air nozzle assembly is provided with a first opening. When the button is pressed, the brake member moves towards the air outlet of the air nozzle assembly, so that the brake pad disengages from the first opening out of the brake groove, so as to unlock the inner air nozzle by the brake member.

[0009] At the first opening, the brake member extends along the reset direction of the brake member to form an inclined guiding surface for guiding the movement of the brake pad.

[0010] The inner air nozzle is provided with a brake pad. One end of the brake member away from the ejector rod is provided with a brake groove. One end of the brake groove close to the air outlet of the air nozzle assembly is provided with a second opening. When the button is pressed, the brake member moves towards the air outlet of the air nozzle assembly, so that the brake pad slides into the brake groove from the second opening, so as to lock the inner air nozzle by the brake member.

[0011] At the second opening, the brake member extends along the active direction of the brake member to form an inclined guiding surface for guiding the movement of the brake pad.

[0012] The brake member includes a braking portion extending towards the inner air nozzle. The end of the braking portion close to the inner air nozzle is provided with a braking surface. When the button is pressed, the brake member moves towards the air outlet of the air nozzle assembly, so that the braking surface abuts against the inner air nozzle, so as to lock the inner air nozzle by the brake member.

[0013] The braking surface includes a first braking surface and a second braking surface. The first braking surface is arranged on the swinging path of the inner air nozzle along the first direction to limit the swinging angle of the inner air nozzle along the first direction. The second braking surface is arranged on the swinging path of the inner air nozzle along the second direction to limit the swinging angle of the inner air nozzle along the second direction.

[0014] A first reset member is arranged on the ejector rod. The first reset member is configured to be compressed when the ejector rod slides against the brake member to slide, and can drive the ejector rod to reset under its own elastic action after the thrust applied to the ejector rod is stopped; or, a second reset member is arranged on the brake member. The second reset member is configured to be compressed when the ejector rod slides against the brake member to slide, and can drive the brake member to reset under its own elastic action after the thrust applied to the ejector rod is stopped.

[0015] The air nozzle assembly includes a base. The base is provided with an installation groove for installing the brake member. The installation groove is provided with a limiting rib extending along the moving direction of the brake member. The brake member is provided with a limiting groove inserted and slidably matched with the limiting rib.

[0016] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0017] 1. The hair dryer of the utility model is easy to use. The braking member arranged in a sliding manner cooperates with the inner nozzle to realize the locking and unlocking of the inner nozzle. Compared with the prior art, there is no need to directly operate the outer nozzle. The driving mechanism drives the braking member to slide, with high operation efficiency and enhanced reliability, facilitating the flexible switching of the state of the inner nozzle; under the condition of setting a button, the user can hold the hair dryer with one hand and operate the button to switch the state of the inner nozzle, which is convenient for the user to operate. Moreover, the user does not need to operate the outer nozzle, which can avoid being scalded by the hot air blown out by the outer nozzle during adjustment in the hot air state, improving the use safety.

[0018] A set of structures composed of the driving mechanism and the braking member can be arranged based on the extension space of the nozzle assembly, with a high degree of compact structure layout, not increasing the volume of the hair dryer, and ensuring the miniaturization of the hair dryer.

[0019] 2. As a preferred implementation manner, the transmission member is a transmission lever rotatably arranged on the main body of the hair dryer. One end of the transmission lever abuts against the ejector rod, and the other end abuts against the button. Pressing the button can push the transmission lever to swing, so that the transmission lever pushes the ejector rod to slide to abut against the braking member to slide and unlock or lock the inner nozzle. By adopting a rotatably arranged transmission member, the transmission of the button to the ejector rod with non-coaxial setting can be realized, improving the flexibility of the button arrangement and ensuring the reliability of the transmission at the same time.

[0020] 3. As a preferred implementation manner, the inner nozzle is provided with a brake piece, and one end of the braking member away from the ejector rod is provided with a brake groove. One end of the brake groove away from the air outlet of the nozzle assembly is provided with a first opening. When the button is pressed, the braking member moves towards the air outlet of the nozzle assembly, so that the brake piece disengages from the first opening of the brake groove, so that the braking member unlocks the inner nozzle. In this implementation manner, pressing the button can unlock the inner nozzle of the braking member. The inner nozzle can swing to change the air flow direction, so as to alternately dry different areas of the hair, prevent the hot air from concentrating on the same position and being easily scalded, and save the user from the action of swinging the hair dryer to alternately blow different areas, making the operation easier and improving the user experience.

[0021] As a preferred embodiment under this implementation manner, the braking member extends along the reset direction of the braking member at the first opening to form an inclined guiding surface for guiding the movement of the brake piece. By setting the inclined guiding surface, after the user cancels the pressing force on the button, it is beneficial to enable the brake piece in the inclined position to quickly slide into the brake groove under the guidance of the guiding surface, thereby realizing accurate and quick locking, and improving the efficiency and reliability of the locking of the inner nozzle.

[0022] 4. As a preferred embodiment, the inner air nozzle is provided with a brake pad, and the end of the brake member away from the ejector rod is provided with a brake groove. One end of the brake groove close to the air outlet of the air nozzle assembly is provided with a second opening. When the button is pressed, the brake member moves towards the air outlet of the air nozzle assembly, so that the brake pad slides into the brake groove from the second opening, so as to lock the inner air nozzle by the brake member. In this embodiment, pressing the button can lock the inner air nozzle by the brake member. At this time, the inner air nozzle cannot swing, which can meet the user's demand for continuous heating at a specific position. When the user needs to switch the state of the inner air nozzle, releasing the button can make the inner air nozzle swing, which is convenient to switch.

[0023] As a preferred example of this embodiment, the brake member extends along the active direction of the brake member at the second opening to form an inclined guiding surface for guiding the movement of the brake pad. By setting the inclined guiding surface, it is beneficial to enable the brake pad in the inclined position to quickly slide into the brake groove under the guidance of the guiding surface, so as to achieve accurate and rapid locking, and improve the efficiency and reliability of locking the inner air nozzle.

[0024] 5. As a preferred embodiment, the brake member includes a braking portion extending towards the inner air nozzle, and the end of the braking portion close to the inner air nozzle is provided with a braking surface. When the button is pressed, the brake member moves towards the air outlet of the air nozzle assembly, so that the braking surface abuts against the inner air nozzle, so as to lock the inner air nozzle by the brake member. In this embodiment, the inner air nozzle is locked by the braking surface abutting against the inner air nozzle. There is no need to set additional matching structures on the inner air nozzle, which can simplify the structure of the inner air nozzle. Moreover, by the braking surface abutting against the end face of the inner air nozzle, stable limiting can be achieved by the abutting cooperation of surface to surface, and the stability of locking the inner air nozzle can be ensured.

[0025] As a preferred example of this embodiment, the braking surface includes a first braking surface and a second braking surface. The first braking surface is arranged on the swinging path of the inner air nozzle along the first direction to limit the swinging angle of the inner air nozzle along the first direction, and the second braking surface is arranged on the swinging path of the inner air nozzle along the second direction to limit the swinging angle of the inner air nozzle along the second direction. This embodiment can limit the swinging amplitude of the inner air nozzle to meet the user's demand for blowing air at a specific angle, and enrich the usage scenarios. For example, when the inner air nozzle is about to swing to the preset angle, pressing the button at this time can lock the inner air nozzle at the preset angle, so that the user can focus on heating a specific position, which helps to improve the user experience.

[0026] 6. As a preferred embodiment, a first reset member is provided on the ejector rod. The first reset member is configured to be compressed when the ejector rod slides against the brake member to make it slide, and can drive the ejector rod to reset under its own elastic action after the thrust applied to the ejector rod stops. On the one hand, the first reset member can achieve the rapid reset of the ejector rod. On the other hand, the first reset member can form a limit for the ejector rod along the axial direction, which can prevent one end of the ejector rod from being easily touched by mistake and broken when the nozzle assembly is not installed, and ensure its service performance.

[0027] A second reset member is provided on the brake member. The second reset member is configured to be compressed when the ejector rod slides against the brake member to make it slide, and can drive the brake member to reset under its own elastic action after the thrust applied to the ejector rod stops. The setting of the second reset member provides conditions for the brake member to reset to lock or unlock the inner nozzle, ensuring the reliability of the state switching of the inner nozzle.

[0028] 7. As a preferred embodiment, the nozzle assembly includes a base. The base is provided with a mounting groove for mounting the brake member. The mounting groove is provided with a limiting rib extending along the moving direction of the brake member. The brake member is provided with a limiting groove inserted and slidably engaged with the limiting rib. By sliding the limiting rib along the limiting groove, the movement direction of the brake member can be strictly restricted, which can improve the working stability of the brake member, so that the brake member and the inner nozzle can form a good matching posture, thereby improving the stability and reliability of the locking or unlocking of the inner nozzle.

[0056] As Figures 1 to 17 shown, the present application provides a hair dryer that is convenient to use, including a hair dryer main body 10 and a nozzle assembly 11 installed at the air outlet end of the hair dryer main body 10. The nozzle assembly 11 includes an outer nozzle 12 and an inner nozzle 13 rotatably installed in the outer nozzle 12. The outer nozzle 12 is provided with a braking member 14 arranged to slide, and the outer nozzle 12 locks the inner nozzle 13 through the braking member 14. The hair dryer main body 10 is provided with a driving mechanism, and the driving mechanism includes a button 15, a push rod 16, and a transmission member 17. One end of the transmission member 17 is in transmission connection with the push rod 16, and the other end is in transmission connection with the button 15. The transmission member 17 is arranged such that when the button 15 is pressed, the push rod 16 is pushed to slide to abut against the braking member 14 to slide and unlock or lock the inner nozzle 13.

[0057] The hair dryer of the present application is convenient to use. The braking member 14 arranged in a sliding manner cooperates with the inner nozzle 13 to realize the locking and unlocking of the inner nozzle 13. Compared with the prior art, there is no need to directly operate the outer nozzle 12. By driving the braking member 14 to slide through the driving mechanism, the operation efficiency is high and the reliability is enhanced, which is convenient for the flexible switching of the state of the inner nozzle 13; under the condition of setting the button 15, the user can hold the hair dryer with one hand and operate the button 15 to switch the state of the inner nozzle 13, which is convenient for the user to operate. Moreover, the user does not need to operate the outer nozzle 12, which can avoid being scalded by the hot air blown out by the outer nozzle 12 during adjustment in the hot air state, improving the use safety. The set of structures composed of the driving mechanism and the braking member 14 can be arranged based on the extended space of the nozzle assembly 11, and the structural arrangement is highly compact, without increasing the volume of the hair dryer, and the miniaturization of the hair dryer can be ensured.

[0058] As Figure 1 shown, the hair dryer main body 10 includes a machine head 101 and a handle 102 connected to the lower part of the machine head 101. A heating member is provided in the machine head 101. The rear end of the machine head 101 is the air inlet end, and the front end (the end facing the user) is the air outlet end. External air flows into the machine head 101, is heated by the heating member and then blown out, which can be used for drying hair or other heating projects. The nozzle assembly 11 and the machine head 101 are, for example, detachably connected. In some embodiments, as Figure 2 shown, the nozzle assembly 11 and the machine head 101 can be positioned and docked through the cooperation of the convex rib 111 and the card slot 103, which is beneficial to the alignment of the ejector rod 16 and the braking member 14 to ensure the reliability of the transmission. Preferably, as Figure 3 shown, the convex rib 111 is provided with a hook 112. By rotating the nozzle assembly 11, the hook 112 is snapped into the card slot 103 of the machine head 101, which is beneficial to improving the connection strength and can prevent the nozzle assembly 11 from being pushed open and falling off.

[0059] When the user uses the hair dryer to realize the state switching of the inner nozzle 13, the user only needs to operate the button 15, which can be operated with one hand and is very convenient. The transmission member 17 is used to transmit the force at the button 15 to the ejector rod 16, playing an intermediate transmission role. The button 15 can be arranged at the position of the machine head 101 or at the position of the handle 102, which can be set according to actual needs. The braking member 14 is used to cooperate with the structure on the inner nozzle 13 to lock the inner nozzle 13. For the user, the user does not need to push and pull the outer nozzle 12 for operation, which is convenient to use. The outer nozzle 12 includes an outer nozzle main body 121 and a base 122, and an accommodating cavity is formed by enclosing the two. The inner nozzle 13 and the braking member 14 are both arranged in the accommodating cavity, making the appearance of the hair dryer simple and beautiful.

[0060] As a preferred embodiment, the transmission member 17 is a transmission lever rotatably arranged on the hair dryer body 10. One end of the transmission lever abuts against the ejector rod 16, and the other end abuts against the button 15. Pressing the button 15 can push the transmission lever to swing, so that the transmission lever pushes the ejector rod 16 to slide to abut against the brake member 14 to slide and unlock or lock the inner nozzle 13.

[0061] By using the rotatably arranged transmission member 17, the transmission of the button 15 arranged non-coaxially to the ejector rod 16 can be realized, which improves the flexibility of the arrangement of the button 15 and ensures the reliability of the transmission at the same time. As Figure 4 and Figure 5 shown, in this embodiment, the button 15 is arranged on the handle 102. Specifically, the button 15 is arranged near the upper end of the handle 102, which is more in line with the user's usage habit. The user can hold the handle 102 with one hand and use the thumb to press the button 15, which is convenient to operate.

[0062] In another embodiment, the button 15 is arranged on the machine head 101. Specifically, it is arranged at the rear end of the machine head 101. When the button 15 and the ejector rod 16 are coaxially arranged, the button 15, the transmission member 17 and the ejector rod 16 are located on the same straight line. The transmission member 17 can adopt a rod-shaped member, which can realize the linear pushing of the ejector rod 16 by the transmission member 17, with good transmission stability and high transmission efficiency. Of course, in Figure 5 this embodiment, since the transmission path from the button 15 to the ejector rod 16 is short, the transmission efficiency can also be guaranteed.

[0063] There are various implementation manners for the cooperation between the brake member 14 and the inner nozzle 13. Any of the following manners can be adopted to realize the switching of the state of the inner nozzle 13.

[0064] In the first embodiment, the inner nozzle 13 is provided with a brake piece 18. One end of the brake member 14 away from the ejector rod 16 is provided with a brake groove 143. One end of the brake groove 143 away from the air outlet of the nozzle assembly 11 is provided with a first opening 1431. When the button 15 is pressed, the brake member 14 moves towards the air outlet of the nozzle assembly 11, so that the brake piece 18 disengages from the brake groove 143 from the first opening 1431, so as to unlock the inner nozzle 13 by the brake member 14.

[0065] In this embodiment, pressing the button 15 can unlock the inner nozzle 13 by the brake member 14. The inner nozzle 13 can swing to change the air flow direction, so as to alternately dry different areas of the hair, prevent the hot air from concentrating on the same position and being easily scalded, and save the user from the action of swinging the hair dryer to alternately blow different areas, making the operation easier and improving the user experience.

[0066] As Figure 9As shown, specifically, the braking member 14 includes a support portion 141 and a braking portion 142. The support portion 141 is provided with a push rod 1411 aligned with the ejector rod 16. The ejector rod 16 abuts against the push rod 1411 to achieve the sliding of the braking member 14. The braking portion 142 is provided with a braking groove 143 for cooperating with the brake pad 18 to lock and unlock the inner air nozzle 13. Preferably, the support portion 141 and the braking portion 142 have a height difference and are not on the same horizontal plane, so as to facilitate the arrangement and sliding under the limited space and shape of the outer air nozzle 12. A first opening 1431 is provided at one end of the braking groove 143 close to the support portion 141, and the other end of the braking groove 143 is closed. As Figure 6 and Figure 7 shown, after the button 15 is pressed, the action is transmitted to the braking member 14 through the transmission member 17 and the ejector rod 16, causing the braking member 14 to move towards the air outlet of the air nozzle assembly 11. At this time, the brake pad 18 escapes from the braking groove 143 through the first opening 1431, realizing the unlocking of the inner air nozzle 13; in the default state, that is, when the button 15 is not pressed, the brake pad 18 falls into the braking groove 143, and at this time the inner air nozzle 13 is locked and cannot swing.

[0067] As a preferred embodiment of this embodiment, the braking member 14 extends along the reset direction of the braking member 14 at the first opening 1431 to form an inclined guiding surface 144 for guiding the movement of the brake pad 18.

[0068] By setting the inclined guiding surface 144, after the user cancels the pressing force on the button 15, it is beneficial to enable the brake pad 18 in the inclined position to quickly slide into the braking groove 143 under the guidance of the guiding surface 144, thereby achieving accurate and rapid locking, and improving the locking efficiency and reliability of the inner air nozzle 13. As Figure 9 shown, two guiding surfaces 144 are relatively provided on both sides of the first opening 1431, in a V shape. Then, no matter which guiding surface 144 the brake pad 18 deflects to, it can be ensured that it quickly slides into the braking groove 143 under the guidance of the guiding surface 144. Among them, the active direction of the braking member 14 refers to the direction close to the air outlet, and the reset direction of the braking member 14 refers to the opposite direction of the active direction, that is, the direction away from the air outlet.

[0069] In the second embodiment, the inner air nozzle 13 is provided with a brake pad 18, and one end of the braking member 14 away from the ejector rod 16 is provided with a braking groove 143. A second opening 1432 is provided at one end of the braking groove 143 close to the air outlet of the air nozzle assembly 11. When the button 15 is pressed, the braking member 14 moves towards the air outlet of the air nozzle assembly 11, so that the brake pad 18 slides into the braking groove 143 from the second opening 1432, so as to lock the inner air nozzle 13 by the braking member 14.

[0070] In this embodiment, pressing the button 15 can lock the inner air nozzle 13 by the braking member 14. At this time, the inner air nozzle 13 cannot swing, which can meet the user's need for continuous heating at a specific position. When the user needs to switch the state of the inner air nozzle 13, releasing the button 15 can make the inner air nozzle 13 swing, which is convenient to switch.

[0071] As Figure 12 shown, specifically, the braking member 14 includes a supporting portion 141 and a braking portion 142. The supporting portion 141 is provided with a push rod 1411 aligned with the ejector rod 16. The ejector rod 16 abuts against the push rod 1411 to realize the sliding of the braking member 14. The braking portion 142 is provided with a braking groove 143 for cooperating with the brake pad 18 to lock and unlock the inner air nozzle 13. Preferably, the supporting portion 141 and the braking portion 142 have a height difference and are not on the same horizontal plane, so as to facilitate arrangement and sliding in the limited space and shape of the outer air nozzle 12. The second opening 1432 is provided at one end of the braking groove 143 away from the supporting portion 141. The other end of the braking groove 143 is closed or open, which is not limited in this application. As Figure 10 and Figure 11 shown, after pressing the button 15, the action is transmitted to the braking member 14 through the transmission member 17 and the ejector rod 16, so that the braking member 14 moves towards the air outlet of the air nozzle assembly 11. At this time, the brake pad 18 slides into the braking groove 143 through the second opening 1432 to lock the inner air nozzle 13. In the default state, that is, when the button 15 is not pressed, the brake pad 18 is located outside the braking groove 143, and at this time, the inner air nozzle 13 is not locked and can swing.

[0072] As a preferred embodiment of this embodiment, the braking member 14 extends to form an inclined guiding surface 144 along the active direction of the braking member 14 at the second opening 1432 for guiding the movement of the brake pad 18.

[0073] By setting the inclined guiding surface 144, it is beneficial to enable the brake pad 18 in an inclined position to quickly slide into the braking groove 143 under the guidance of the guiding surface 144, so as to achieve accurate and rapid locking, and improve the locking efficiency and reliability of the inner air nozzle 13. As Figure 12 shown, two guiding surfaces 144 are relatively provided on both sides of the second opening 1432, presenting a V shape. Then, no matter which guiding surface 144 the brake pad 18 deflects to, it can be ensured that it quickly slides into the braking groove 143 under the guidance of the guiding surface 144. Among them, the active direction of the braking member 14 refers to the direction close to the air outlet, and the reset direction of the braking member 14 refers to the opposite direction of the active direction, that is, the direction away from the air outlet.

[0074] In the third embodiment, the brake member 14 includes a braking portion 142 extending toward the inner nozzle 13. A braking surface 145 is provided at the end of the braking portion 142 close to the inner nozzle 13. When the button 15 is pressed, the brake member 14 moves toward the air outlet of the nozzle assembly 11, so that the braking surface 145 abuts against the inner nozzle 13 to lock the inner nozzle 13 by the brake member 14.

[0075] In this embodiment, the inner nozzle 13 is locked by the braking surface 145 abutting against the inner nozzle 13. There is no need to provide an additional matching structure on the inner nozzle 13, which can simplify the structure of the inner nozzle 13. Moreover, by the braking surface 145 abutting against the end face of the inner nozzle 13, stable limiting can be achieved by the abutting fit between the surfaces, ensuring the stability of the locking of the inner nozzle 13.

[0076] As Figure 14 shown, the brake member 14 includes a support portion 141 and a braking portion 142. The support portion 141 is provided with a push rod 1411 aligned with the ejector rod 16. The ejector rod 16 abuts against the push rod 1411 to realize the sliding of the brake member 14. The braking portion 142 is provided with a braking surface 145. When the braking surface 145 abuts against the end face of the inner nozzle 13, the inner nozzle 13 is locked. Specifically, after the button 15 is pressed, the action is transmitted to the brake member 14 through the transmission member 17 and the ejector rod 16, so that the brake member 14 moves toward the air outlet of the nozzle assembly 11. When the braking surface 145 abuts against the end face of the inner nozzle 13, the inner nozzle 13 is locked. In the default state, that is, when the button 15 is not pressed, the braking surface 145 does not abut against the inner nozzle 13, and the inner nozzle 13 can swing.

[0077] As a preferred embodiment of this embodiment, the braking surface includes a first braking surface 146 and a second braking surface 147. The first braking surface 146 is arranged on the swinging path of the inner nozzle 13 in the first direction to limit the swinging angle of the inner nozzle 13 in the first direction. The second braking surface 147 is arranged on the swinging path of the inner nozzle 13 in the second direction to limit the swinging angle of the inner nozzle 13 in the second direction.

[0078] As Figure 15 and Figure 16 shown, this embodiment can limit the swinging amplitude of the inner nozzle 13 to meet the user's need for blowing air at a specific angle and enrich the usage scenarios. For example, when the inner nozzle 13 is about to swing to the preset angle, pressing the button 15 at this time can lock the inner nozzle 13 at the preset angle, so that the user can focus on heating a specific position, which helps to improve the user experience.

[0079] On the basis of the above three implementation manners, further, as a preferred implementation manner, a first reset member 19 is provided on the ejector rod 16. The first reset member 19 is configured to be compressed when the ejector rod 16 slides against the brake member 14 to cause the brake member 14 to slide, and can drive the ejector rod 16 to reset under its own elastic action after the thrust applied to the ejector rod 16 is stopped.

[0080] As Figure 5 shown, on the one hand, the first reset member 19 can achieve the rapid reset of the ejector rod 16. On the other hand, the first reset member 19 can form an axial limit for the ejector rod 16, which can prevent one end of the ejector rod 16 from being easily touched by mistake and broken when the nozzle assembly 11 is not installed, ensuring its service performance. The first reset member 19 is specifically a spring.

[0081] Further, as a preferred implementation manner, a second reset member 20 is provided on the brake member 14. The second reset member 20 is configured to be compressed when the ejector rod 16 slides against the brake member 14 to cause the brake member 14 to slide, and can drive the brake member 14 to reset under its own elastic action after the thrust applied to the ejector rod 16 is stopped.

[0082] As Figure 5 、 Figure 8 or Figure 13 shown, the setting of the second reset member 20 provides conditions for the brake member 14 to reset to lock or unlock the inner nozzle 13, ensuring the reliability of the state switching of the inner nozzle 13. The second reset member 20 is specifically a spring.

[0083] To implement the installation of the second reset member 20, as Figure 9 、 Figure 12 、 Figure 14 and Figure 17 shown, a positioning post 148 for sleeving the second reset member 20 is provided on the brake member 14, and a limit seat 1211 is provided on the inner wall of the outer nozzle body 121. One end of the second reset member 20 is sleeved on the positioning post 148 and the other end abuts against the limit seat 1211, which can prevent the second reset member 20 from running off. Preferably, a retaining rib 1212 is provided in the limit seat 1211, and the end face of the retaining rib 1212 is perpendicular to the extending direction of the second reset member 20, which can ensure that the second reset member 20 is along its axial direction during compression and stretching, improving its working stability. In the above first implementation manner, preferably, the second reset member 20 has a certain compression amount in the natural state, and the brake member 14 can be stably pushed to one side under the action of the second reset member 20, thereby improving the stability of the inner nozzle 13 in the locked state.

[0084] Further, as a preferred embodiment, the air nozzle assembly 11 includes a base 122. The base 122 is provided with an installation groove 21 for installing the braking member 14. The installation groove 21 is provided with a limiting rib 211 extending along the moving direction of the braking member 14. The braking member 14 is provided with a limiting groove 149 inserted and slidably engaged with the limiting rib 211.

[0085] As Figure 8 or Figure 13 shown, by sliding the limiting rib 211 along the limiting groove 149, the movement direction of the braking member 14 can be strictly restricted, the working stability of the braking member 14 can be improved, so that the braking member 14 and the inner air nozzle 13 can form a good matching posture, thereby improving the stability and reliability of locking or unlocking the inner air nozzle 13. There are two groups of the limiting rib 211 and the limiting groove 149, so that the braking member 14 slides more smoothly and the transmission efficiency is improved.

[0086] Further, the base 122 is provided with a hollow guide post 22. The braking member 14 is provided with a push rod 1411 aligned with the ejector rod 16. The push rod 1411 can slide along the guide post 22 to further restrict the sliding direction of the braking member 14 and improve its working stability.
