DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] like Figure 1-11 As shown, the utility model provides an air nozzle with hidden and exposed comb teeth, comprising an outer shell 1 and an inner connecting member 2, wherein one end of the outer shell 1 is provided with an air inlet 11, and the other end is movably connected to the inner connecting member 2, an air cavity 3 is provided between the outer shell 1 and the inner connecting member 2, the inner connecting member 2 is an arc-shaped plate recessed toward the air inlet 11, and the inner connecting member 2 is provided with a plurality of first air outlets 21 and a plurality of comb teeth 22 extending away from the air inlet 11, the air cavity 3 is communicated with the air inlet 11 and the first air outlet 21 respectively;

[0033] The inner connecting member 2 is disposed in the outer shell 1 and can move closer to or farther away from the air inlet 11 , so as to enable the comb teeth 22 to retract inward or extend outward relative to the outer shell 1 .

[0034] like Figure 1-3As shown, when in use, after the nozzle is connected to the output end of the hair dryer, the air flow enters the air cavity 3 from the air inlet 11, and is then blown out from the first air outlet 21 toward the consumer's hair, thereby achieving the effect of drying the hair; at the same time, since the end surface of the inner connecting member 2 facing the hair is provided with a plurality of comb teeth 22, the consumer can bring the nozzle close to the hair when in use, and use the comb teeth 22 to simultaneously style the hair under the drying effect of the first air outlet 21; compared to daily use, in which consumers need to use a hair dryer, a comb, and their hands to style their hair, the provision of comb teeth 22 on the nozzle can effectively improve the multifunctional integration of the nozzle, so that consumers can use the nozzle to dry their hair while also having the comb teeth 22 to straighten and style their hair;

[0035] Specifically, when the air nozzle is actually used, the movement distance of the inner connecting member 2 in the outer shell 1 can be adjusted. That is, when the inner connecting member 2 moves inward toward the air inlet 11 of the outer shell 1, the comb teeth 22 will simultaneously move inward toward the inside of the outer shell 1, causing the comb teeth 22 to retract. At this time, the inner peripheral wall of the outer shell 1 and the outer end surface of the inner connecting member 2 jointly form a styling cavity 6, and the comb teeth 22 are exactly located in the styling cavity 6. When in use, the consumer can coil the hair in the styling cavity 6. Under the effect of the air outlet 21, the coiled hair is simultaneously dried and hot-ironed, which not only increases the fluffiness of the hair, but also allows for curly hair styling and curly hair styling maintenance.

[0036] When the inner connecting member 2 moves outward away from the air inlet 11, the comb teeth 22 move toward the outside of the housing 1, so that the comb teeth 22 extend outward. When the consumer uses the comb, the comb teeth 22 can penetrate deeper into the consumer's hair to comb and style the hair.

[0037] Therefore, by adjusting the inward and outward movement of the inner connecting member 2 in the outer shell 1, the comb teeth 22 are driven to retract and extend, thereby realizing multiple functions of curling, perming and combing hair, thereby helping consumers to achieve fast hair styling operations and improving consumers' user experience.

[0038] Specifically, such as Figure 4 As shown, the plurality of comb teeth 22 are evenly distributed on the end surface of the inner connecting member 2 away from the air inlet 11 , and the plurality of first air outlets 21 are evenly distributed between the comb teeth 22 ;

[0039] Furthermore, the diameter of the first air outlet 21 is smaller than the diameter of the connection between the comb teeth 22 and the inner connecting member 2; by arranging a plurality of evenly distributed comb teeth 22 and the first air outlet 21 on the inner connecting member 2, the air outlet of the nozzle is more uniform, and the combing effect of the comb teeth 22 is better.

[0040] In order to further illustrate the specific embodiments of the present invention, the following three examples are provided, including but not limited to:

[0041] like Figure 2-3 As shown, in the first embodiment, a connecting column 12 is provided in the housing 1, a connecting cavity 121 is provided in the connecting column 12, and a connecting rod 23 corresponding to the connecting column 12 is provided on the inner connecting member 2, and the connecting rod 23 is inserted into the connecting cavity 121; by the arrangement of the connecting column 12 and the connecting rod 23, the inner connecting member 2 has a guiding effect when moving inward and outward, making its movement more stable and smooth, thereby improving the consumer's user experience;

[0042] It should be noted that the connecting rod 23 in this embodiment is inserted into the connecting column 12. Under the same guiding effect, the connecting column 12 can also be configured to be inserted into the connecting rod 23 without affecting the actual use effect.

[0043] Furthermore, in order to fix the moving position of the inner connecting member 2, in this embodiment, the connecting column 12 and the connecting rod 23 are connected by a thread. Therefore, when in use, the consumer can rotate the inner connecting member 2 and, under the action of the thread, screw the inner connecting member 2 into the outer shell 1, thereby achieving the purpose of retracting and extending the comb teeth 22. At the same time, through the threaded arrangement of the connecting rod 23 and the connecting column 12, the retraction and extension of the comb teeth 22 can be adjusted to achieve a stepless use effect, so that the consumer can adjust the retraction or extension distance of the comb teeth 22 according to their own needs, thereby meeting the consumer's personalized needs for the telescopic position of the comb teeth 22.

[0044] Preferably, the diameter of the connecting rod 23 can be set to be slightly larger than the inner diameter of the connecting column 12, so that the rotation of the connecting rod 23 has a damping or deceleration effect, thereby improving the connection firmness and usage stability of the outer shell 1 and the inner connecting member 2;

[0045] Furthermore, a plurality of protrusions 24 are provided on the edge of the inner connecting member 2, and an annular step 13 corresponding to the protrusion 24 is provided on the inner wall of the outer shell 1. When the inner connecting member 2 moves inward toward the air inlet 11, when the protrusion 24 abuts against the annular step 13 to limit the continued inward movement of the inner connecting member 2, this is the maximum inward movement state of the inner connecting member 2. The setting of the protrusion 24 and the annular step 13 has a limiting effect on the movement of the inner connecting member 2, and can also improve the stability of use of the maximum inward movement state.

[0046] like Figure 5-6As shown, in the second embodiment, in order to achieve the effect of inward and outward movement of the inner connecting member 2, the inner peripheral wall of the shell 1 is provided with a "Z"-shaped card slot 14, and the edge of the inner connecting member 2 is provided with a protrusion 24 corresponding to the card slot 14; wherein, the card slot 14 includes a longitudinal groove 141, a first transverse groove 142 and a second transverse groove 143, the first transverse groove 142 and the second transverse groove 143 are respectively arranged at the two ends of the longitudinal groove 141, and the first transverse groove 142 and the second transverse groove 143 are respectively arranged on the opposite side of the longitudinal groove 141; when in use, when the protrusion 24 is slidably connected in the longitudinal groove 141, the inner connecting member 2 can be moved inward or outward; when the protrusion 24 moves to the end of the longitudinal groove 141 and is engaged in the first transverse groove 142 or the second transverse groove 143, the inner connecting member 2 can be fixed in the inward or outward state respectively;

[0047] It should be noted that, in this embodiment, only two engaging positions are provided in the engaging slot 14, namely the first transverse slot 142 and the second transverse slot 143. In actual production, the engaging slot 14 may be provided with multiple engaging positions to form a multi-level adjustment of the movement of the inner connecting member 2, thereby improving the convenience of use for consumers.

[0048] Further, if Figure 7 As shown, in order to improve the convenience of assembling the air nozzle, a detachably connected inner ring 15 is provided in the outer shell 1, and the inner ring 15 is fixedly abutted against the inner peripheral wall of the outer shell 1. The clamping groove 14 is provided on the inner ring 15, and the top of the inner ring 15 (the end close to the air inlet 11) is provided with a mounting opening 151 connected to the clamping groove 14; during assembly, the protrusion 24 in the inner connecting member 2 is first assembled into the clamping groove 14 from the mounting opening 151, and then the inner ring 15 and the inner connecting member 2 are assembled into the outer shell 1 to complete the assembly; the provision of the inner ring 15 effectively improves the convenience of assembling the air nozzle, makes the air nozzle structure more concise, and is conducive to improving the assembly and production efficiency of the air nozzle;

[0049] Preferably, a connecting column 12 is provided in the housing 1, a connecting cavity 121 is provided in the connecting column 12, and a connecting rod 23 corresponding to the connecting column 12 is provided on the inner connecting member 2, and the connecting rod 23 is inserted into the connecting cavity 121; that is, the plug-in structure of the connecting column 12 and the connecting rod 23 is adopted in both the first and second embodiments;

[0050] It should be noted that the connecting column 12 and the connecting rod 23 of the first embodiment are connected by threads, and the telescopic position of the comb teeth 22 in the inner connecting member 2 is adjusted by rotation; while in the second embodiment, the structures mainly used to adjust the telescopic position of the comb teeth 22 are the locking groove 14 and the protrusion 24. Therefore, the purpose of providing the connecting column 12 and the connecting rod 23 is mainly to guide the adjustment movement of the inner connecting member 2, thereby improving the adjustment stability of the inner connecting member 2.

[0051] Specifically, such as Figure 8 As shown, the connecting column 12 is coaxially arranged with the air inlet 11, and the central axis of the connecting column 12 coincides with the central axis of the overall structure of the air nozzle. A plurality of connecting plates 16 are fixed between the connecting column 12 and the housing 1, and gaps 17 are provided between adjacent connecting plates 16, which are respectively connected to the air cavity 3 and the air inlet 11. Through the arrangement of the connecting plates 16 and the gaps 17, the connecting column 12 can be stably fixed at the central axis position in the air nozzle, while allowing air to flow from the air inlet 11 through the gaps 17 and into the air cavity 3, thereby improving the connection stability between the connecting column 12 and the housing 1.

[0052] Furthermore, an end of the connecting column 12 close to the air inlet 11 is provided with a curved surface 122 with a central portion extending toward the air inlet 11. The curved surface 122 allows the airflow to be diverted and guided when passing through the end of the connecting column 12. This not only effectively reduces convection of the airflow, but also allows the airflow to flow evenly to various areas within the air cavity 3, thereby making the airflow from the first air outlet 21 more uniform.

[0053] Preferably, the arc surface 122 may also be designed as a conical surface.

[0054] Specifically, such as Figure 4 As shown in FIG. 9 , at least a portion of the comb teeth 22 is provided with a channel 221 , and at least one second air outlet 222 is provided at an end of the comb teeth 22 away from the air inlet 11 . The channel 221 is communicated with the air cavity 3 and the second air outlet 222 , respectively. Through the provision of the second air outlet 222 , when a consumer uses the comb teeth 22 to comb their hair, airflow can be blown from the second air outlet 222 toward the roots of the consumer's hair, thereby effectively increasing the volume of the hair and making hair styling operations more convenient for the consumer.

[0055] It should be noted that in actual production, part or all of the comb teeth 22 may also be solid structures, and in actual use, when used as a comb, a second air outlet 222 is provided in the comb teeth 22 for better use effect;

[0056] Further, if Figure 9 As shown, the comb teeth 22 further include inner teeth 223 and outer teeth 224. The inner teeth 223 are closer to the center of the inner connecting member 2 than the outer teeth 224, and the plurality of inner teeth 223 and outer teeth 224 are arranged in a circular array around the center of the inner connecting member 2; wherein, the inner teeth 223 are provided with three second air outlets 222, and the outer teeth 224 are provided with two second air outlets 222;

[0057] Preferably, the three second air outlets 222 of the inner teeth 223 are evenly spaced around the central axis of the inner teeth 223, so that the air flow can flow out evenly around the inner teeth 223 to improve the uniform air outlet effect at the inner teeth 223; the two second air outlets 222 of the outer teeth 224 are arranged to face the center position of the inner connecting part 2, so that when the air flow flows out from the second air outlet 222 in the outer teeth 224, it can flow more concentratedly to the center position of the inner connecting part 2, making the air outlet more concentrated.

[0058] In order to achieve the same purpose of extending and retracting the comb teeth 22, a specific implementation scheme of a third embodiment is provided below;

[0059] like Figure 10-11 As shown, in the third embodiment, the housing 1 includes a rear cover 4 and a connecting cover 5 with openings at both ends and a trumpet-shaped structure; the rear cover 4 and the inner connecting member 2 are integrally formed or separately formed and then assembled and fixed into one, and the connecting cover 5 and the inner connecting member 2 are detachably connected by snap-fitting;

[0060] Specifically, an annular ridge 25 is provided on the outer edge of the inner connecting member 2, and a plurality of "L"-shaped fixing grooves 26 are provided below the ridge 25. The inner wall of the edge of the first opening 53 with a smaller diameter of the connecting cover 5 is provided with a relief groove 51 corresponding to the fixing groove 26 and a fixing block 52 arranged adjacent to the relief groove 51. The fixing block 52 and the relief groove 51 are arranged in a staggered manner.

[0061] When in use, the connecting cover 5 is placed on the inner connecting member 2, the fixing groove 26 is located in the avoiding groove 51, and then the connecting cover 5 is rotated so that the fixing block 52 on the connecting cover 5 is engaged with the fixing groove 26, thereby achieving the clamping and fixing of the connecting cover 5 and the inner connecting member 2;

[0062] It should be noted that, through the above-mentioned clamping structure, the installation directions of the connecting cover 5 and the inner connecting member 2 can be interchanged; when the second opening 54 of the connecting cover 5 with a larger diameter faces the comb teeth 22, the inner wall of the connecting cover 5 and the inner connecting member 2 jointly form the molding cavity 6, and the comb teeth 22 are in a retracted state at this time; when the connecting cover 5 is installed in the reverse direction, that is, when the second opening 54 of the connecting cover 5 faces the air inlet 11, the peripheral wall of the connecting cover 5 is more sleeved on the back cover 4, and the comb teeth 22 are in an extended state at this time; therefore, through the detachable and direction-changeable installation method of the connecting cover 5 and the inner connecting member 2, the retracted and extended states of the comb teeth 22 can also be achieved;

[0063] Furthermore, in order to improve the clamping stability of the connecting cover 5 and the inner connecting part 2, a wave point 261 is also provided in the fixing groove 26, and a notch 521 corresponding to the wave point 261 is provided on the fixing block 52. When the connecting cover 5 and the inner connecting part 2 are clamped into place, the wave point 261 is just clamped in the notch 521, thereby effectively improving the clamping stability of the connecting cover 5 and the inner connecting part 2. Since the wave point 261 is an arc surface design, when the connecting cover 5 and the inner connecting part 2 are unlocked, it is only necessary to rotate the connecting cover 5 in the opposite direction with force to achieve the disassembly of the connecting cover 5 and the inner connecting part 2.

[0064] The following is a detailed description of the working principle of the utility model;

[0065] When in use, the air inlet 11 of the nozzle is first connected and fixed to the air outlet end of the hair dryer, and then the hair dryer is turned on. The airflow enters the air cavity 3 from the air inlet 11 and is evenly blown toward the consumer's hair from the first air outlet 21 and the second air outlet 222 respectively. At the same time, the consumer can adjust the retracted or extended state of the comb teeth 22 by rotating the thread, adjusting the clamping position of the card slot 14, or adjusting the installation direction of the connecting cover 5.

[0066] When the comb teeth 22 are retracted, the styling cavity 6 is formed between the outer shell 1 or the connecting cover 5 and the inner connecting member 2. Consumers can coil their hair in the styling cavity 6 and perform hot air perming to achieve curly hair styling or daily maintenance of curly hair styling.

[0067] When the comb teeth 22 are extended outward, the comb teeth 22 can penetrate deep into the roots of the hair to comb the hair, and at the same time, the hair can be fluffed and shaped with the cooperation of the second air outlet 222 .

[0068] The innovation of the present utility model lies in that by providing a first air outlet, comb teeth and a second air outlet on the inner connecting member, consumers can straighten and style their hair while drying it; at the same time, by adjusting the telescopic adjustment of the inner connecting member, the comb teeth are retracted inward to form a styling cavity for hair curling and daily maintenance, or the comb teeth are extended outward to comb and style the hair, thereby realizing multifunctional and fast hair styling operations for consumers.

[0069] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0070] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
