DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-5 As shown, the present invention discloses an adjustable air nozzle, comprising a shell 1, wherein one end of the shell 1 is provided with an air inlet 13, and the other end is provided with an air outlet 14, wherein an air flow channel 15 is provided in the shell 1 and is communicated with the air inlet 13 and the air outlet 14 respectively, wherein the shell 1 is further provided with an air regulating mechanism 2, wherein the air regulating mechanism 2 comprises at least one air shield 21 arranged in the air flow channel 15 and a driving assembly 22 arranged on the shell 1; wherein one end of the air shield 21 close to the air inlet 13 is hingedly arranged with the inner wall of the air flow channel 15, and the other end extends toward the air outlet 14 and is connected with the driving assembly 22, wherein the driving assembly 22 can drive the air shield 21 to swing around a hinge axis L along the width direction in the air flow channel 15 to control the air outlet area of ​​the air outlet 14; Furthermore, the windshield plates 21 are provided with two in total and are symmetrically arranged in the airflow channel 15 with respect to the central axis E of the housing 1, and are driven by the driving component 22 to move closer to or farther from each other; When in use, the air inlet 13 of the housing 1 is connected to the output end of the hair dryer (not shown). After the hair dryer is started, the airflow enters the airflow channel 15 from the air inlet 13 and passes through the ventilation gap between the wind shields 21, and finally is discharged from the housing 1 from the air outlet 14; at the same time, the two wind shields 21 are moved closer to or farther from each other by adjusting the driving assembly 22 to adjust the size of the ventilation gap between the wind shields 21, thereby achieving the width adjustment of the air outlet area at the air outlet 14, and further achieving the centralized or diffuse adjustment of the air volume; When the consumer needs to diffuse the air, the two windshields 21 only need to be moved away from each other by the driving assembly 22 to increase the ventilation gap between the two, thereby achieving the purpose of diffusing the air, which is convenient for the consumer to dry or straighten the hair in a large area; When the consumer needs concentrated air flow, the two wind shields 21 are moved closer to each other by the driving assembly 22 to reduce the ventilation gap between the two, thereby achieving the purpose of concentrated air flow and increasing wind pressure, so that the consumer can use the same air nozzle to dry the hair locally and quickly. Through the adjustable setting of the wind shield 21 and the driving assembly 22, the same air nozzle has the functions of concentrated air outlet and diffuse air outlet, so that consumers can perform hair straightening or quick hair drying according to their own needs, thereby effectively solving the problem in the prior art that the single air nozzle structure causes consumers to have cumbersome hair straightening or hair drying operations and the need to purchase different air nozzles in sets for different styling needs, resulting in waste of resources.

[0031] Specifically, Figure 3-4 As shown, the housing 1 comprises an inner housing 11 and an outer housing 12 which are detachably connected, the outer housing 12 is connected to the inner housing 11 by snaps, the outer housing 12 is sleeved on the inner housing 11 and together form an installation cavity 3, and the drive assembly 22 is arranged in the installation cavity 3; Furthermore, if Figure 6-11 As shown, the wind shield 21 is provided with a driving column 211, and the inner shell 11 is provided with an arc groove 111 corresponding to the position of the driving column 211 and connecting the airflow channel 15 and the installation cavity 3. The driving column 211 passes through the arc groove 111 and extends into the installation cavity 3 to be rotatably connected with the driving assembly 22. Through the arrangement of the arc groove 111 and the driving column 211, the driving assembly 22 can realize the overall swing of the wind shield 21 by driving the swing of the driving column 211. The swing structure is simple and convenient for the assembly, replacement and maintenance of the air nozzle. Furthermore, the driving assembly 22 includes a rotating seat 221 rotatably connected to the installation cavity 3 and a crank arm 222 slidably connected to the installation cavity 3, the rotating seat 221 is provided with two symmetrically arranged driving posts 2211, and the crank arms 222 are provided with two, one end of the two crank arms 222 is respectively connected to the two driving posts 2211 one by one, and the other end of the two crank arms 222 is connected to the driving posts 1 211 on the two windshield plates 21 one by one; that is, by rotating the The rotating seat 221 enables the second driving column 2211 to drive the crank arm 222 to move along the width direction, thereby driving the first driving column 211 and the windshield 21 to swing, and the crank arms 222 are arranged in pairs and are rotatably connected to one of the rotating seats 221, so that one of the rotating seats 221 can synchronously drive the two windshields 21 to swing, thereby making the driving structure of the driving assembly 22 more concise and highly practical, and can effectively optimize the internal structure of the installation cavity 3, thereby increasing the service life of the driving assembly 22; Preferably, in order to further improve the swing stability of the curved arm 222, the curved arm 222 is provided with a guide groove 2221 extending along the width direction of the air flow channel 15, and the inner wall of the mounting cavity 3 is fixedly provided with a guide column 31 corresponding to the guide groove 2221, and the guide column 31 is slidably connected in the guide groove 2221; during the swinging process of the curved arm 222, the guide column 31 abuts against the guide groove 2221, and has a guiding, correcting and limiting effect on the swinging of the curved arm 222, thereby effectively improving the swing stability of the curved arm 222.

[0032] Specifically, Fig.12 As shown in FIG. 4 , a rotating groove 32 corresponding to the position of the rotating seat 221 is further provided on the inner wall of the mounting cavity 3, and a rotating column 322 penetrating the rotating seat 221 is provided at the center of the rotating groove 32, and the rotating seat 221 is rotatably connected to the rotating groove 32 with the rotating column 322 (rotating axis Q) as the rotation center; Furthermore, at least one limiting groove 321 is provided on the inner wall of the rotating groove 32, and a limiting block 2212 corresponding to the position of the limiting groove 321 is provided on the peripheral wall of the rotating seat 221, and the limiting block 2212 is slidably connected in the limiting groove 321; In this embodiment, the limiting groove 321 is further provided with a first limiting end 3212 and a second limiting end 3213. When the rotating seat 221 rotates counterclockwise to make the limiting block 2212 abut against the first limiting end 3212, the ventilation gap between the two wind shields 21 is maximized, and the air outlet area is also maximized (e.g., Figure 6-7 When the rotating seat 221 rotates clockwise to make the limit block 2212 abut against the second limit end 3213, the ventilation gap between the two wind shields 21 is the smallest, and the air outlet area is also the smallest (as shown in FIG. Figure 10-11 shown); It should be noted that, during actual assembly, the positions of the second driving posts 2211 corresponding to the two crank arms 222 may be exchanged with each other, so that the rotating seat 221 rotates in opposite directions under the same switching effect; Furthermore, if Fig.12 As shown, a plurality of shift grooves 3211 are provided at intervals on the inner wall of the limit groove 321, and a shift block 2213 corresponding to the shift groove 3211 is provided on the peripheral wall of the limit block 2212, and the shift block 2213 is clamped in the shift groove 3211; In this embodiment, there are three gear slots 3211, namely slot one 3214, slot two 3215 and slot three 3216; the slot one 3214 is located on one side of the gear slot 3211 close to the first limit end 3212, and when the gear block 2213 is respectively connected to the slot one 3214, slot two 3215 and slot three 3216, the two wind shields 21 can be respectively formed into fully open, half open and fully closed states, and the air outlet area is the largest in the fully open state (such as Figure 6-7 ), the air outlet area is the smallest when it is fully closed (such as Figure 10-11 ), while the air outlet area in the half-open state is between the maximum and minimum (such as Figure 8-9 ); In actual production, more or fewer gears can be set to adapt to consumer needs; At the same time, the peripheral walls of the gear slot 3211 and the gear block 2213 are both arc-surface structures, and the arc-surface structure makes the rotating seat 221 more damped when switching gears, thereby improving the user experience of consumers.

[0033] Specifically, Figure 1-3 As shown, in order to improve the convenience of rotating the rotating seat 221, the housing 12 is provided with a mounting hole 121 communicating with the mounting cavity 3 and a rotating cover 122 corresponding to the position of the mounting hole 121, and the rotating cover 122 passes through the mounting hole 121 and is fixedly connected to the rotating seat 221. When in use, the rotating seat 221 can be driven to rotate synchronously by rotating the rotating cover 122 disposed on the outer peripheral wall of the housing 12, so that the overall appearance of the air nozzle is more concise and has higher practicality; Furthermore, if Fig.13 As shown, the rotating cover 122 is further provided with two mounting posts 124 which are respectively arranged in one-to-one correspondence with the two second driving posts 2211, and the second driving posts 2211 are provided with fixing holes 2214 corresponding to the mounting posts 124, and the mounting posts 124 are inserted into the fixing holes 2214 to realize the fixed or detachable connection between the rotating seat 221 and the rotating cover 122; Furthermore, a handle 123 may be provided on the outer wall of the rotating cover 122 to provide more points of force for consumers to rotate the rotating cover 122, thereby improving the convenience of switching the air outlet area.

[0034] Specifically, since the air outlet 14 and the air flow channel 15 are designed in a straight line in the width direction, without any support, the housing 1 is easily squeezed by external force, so that the air outlet 14 and the air flow channel 15 are compressed, deformed or even damaged. At the same time, there may also be a problem that the windshield 21 cannot be swung and adjusted under pressure, affecting its service life; Therefore, if Figure 2-4As shown, in this embodiment, a support block 151 arranged on one side of the wind shield 21 is fixed in the air flow channel 15, and the support block 151 is used to support and fix the opening angle of the air outlet 14, thereby effectively improving the opening support of the air outlet 14 and the air flow channel 15, and further improving the durability of the air nozzle; at the same time, because the support block 151 is arranged on one side of the wind shield 21, when the wind shield 21 swings, the support block 151 has a certain limiting effect on the swing of the wind shield 21, thereby avoiding the risk of the two wind shields 21 being too close to affect the air outlet and colliding with each other and being damaged; Similarly, in order to further consolidate and support the space of the installation cavity 3, a plurality of ribs 33 fixed on the peripheral wall of the installation cavity 3 are further provided in the installation cavity 3. During installation, the two ends of the ribs 33 respectively abut against the inner shell 11 and the outer shell 12, thereby playing a role in supporting the installation cavity 3.

[0035] Specifically, an air guide portion 16 with a conical structure is further provided on one end of the shell 1 close to the air inlet 13. When the air flow enters the shell 1 from the air inlet 13, the conical surface design in the air guide portion 16 can effectively guide the air flow into the air flow channel 15, thereby reducing convection and increasing the air intake.

[0036] The working principle of the present invention is described in detail below; In actual use, the air nozzle is first installed at the output end of the hair dryer, so that the airflow blown by the hair dryer can enter the airflow channel 15 through the air inlet 13, and then the airflow passes through the ventilation gap between the two wind shields 21 and is discharged from the air outlet 14. At this time, the two wind shields 21 can be controlled to move closer or farther from each other by rotating the rotating cover 122 to control the air outlet area of ​​the air nozzle in the width direction; When the rotating cover 122 is rotated to make the gear block 2213 on the rotating seat 221 engage with the slot 1 3214, the two wind shields 21 are in a fully open state, and the air outlet area is maximized, which is suitable for drying or straightening hair in a wide range; When the rotating cover 122 is rotated to make the gear block 2213 on the rotating seat 221 engage with the slot 3 3216, the two wind shields 21 are in a fully closed state. At this time, the air outlet area is the smallest and the air volume is the largest, which is suitable for local rapid drying or styling of hair. When the rotating cover 122 is rotated to engage the gear block 2213 on the rotating seat 221 with the second slot 3215, the two wind shields 21 are in a half-open state. At this time, the air outlet area and air volume are at an average level, which is suitable for regular use by consumers.

[0037] The innovation of the present invention lies in that two wind shields are arranged in the air flow channel, which can be moved closer or farther away from each other to adjust the air outlet width and area, so that consumers can quickly adjust the air outlet area and air volume on the same air nozzle, thereby effectively improving the efficiency of consumers' quick drying and quick hair styling, so as to improve consumers' usage experience; at the same time, by connecting two curved arms on a rotating seat at the same time to drive the two wind shields to swing synchronously, the air nozzle structure is simpler and more practical, which is convenient for rapid assembly of the air nozzle and replacement and maintenance of parts.
