[0039] In the related art, in order to increase the air output of the hair dryer, an air inlet 310 is often set on the body of the hair dryer. However, in actual use, the effect of setting the air inlet 310 on the body of the hair dryer on increasing the air output is not obvious. In some technical solutions, an air-increasing accessory is set, and the air-increasing component is installed at the air outlet 201 when the air output needs to be increased. However, the structure of the air-increasing accessory is complicated and requires additional processing, and the cost of use is relatively high.

[0040] The embodiments of the present utility model refer to Figure 1-Figure 4 As shown, a nozzle assembly of a hair dryer and a hair dryer are provided.

[0041] According to an embodiment of the present utility model, please refer to Figure 1 and Figure 2According to the embodiment of the utility model, the nozzle assembly of the hair dryer includes a base 100; a nozzle 200 installed on the base 100; a shell 300, which is arranged on the base 100, and an installation cavity 101 for installing the nozzle 200 is formed between the shell 300 and the base 100, an air outlet channel 400 is defined between the shell 300 and the nozzle 200, and an air inlet 310 is opened on the side wall of the shell 300, and the air inlet 310 is connected to the air outlet channel 400.

[0042] It can be understood that, in this embodiment, the housing 300 can be covered on the base 100, so that a mounting cavity 101 for mounting the air nozzle 200 is formed between the base 100 and the housing 300, and the air nozzle 200 can be arranged in the mounting cavity 101. The mounting structure composed of the base 100 and the housing 300 provides a stable installation environment for the air nozzle 200, and at the same time, the mounting cavity 101 also provides a certain degree of protection for the air nozzle 200, preventing external factors (such as dust, moisture, etc.) from directly contacting the air nozzle 200, thereby extending its service life.

[0043] In an optional embodiment, the air nozzle 200 is partially disposed in the installation cavity 101, and the air outlet 201 of the air nozzle 200 extends out of the installation cavity 101. Since the air outlet 201 extends out of the installation cavity 101, the size and shape of the air outlet 201 may not be restricted by the installation cavity 101, so that the blowing area of ​​the air outlet 201 may be larger, and such a design helps to increase the air output and improve the blowing efficiency.

[0044] Of course, the air nozzle 200 may also be completely located in the installation cavity 101 , and the installation cavity 101 can provide protection for the air nozzle 200 and prevent the user from accidentally touching the rotating air nozzle 200 .

[0045] In some embodiments, the air outlet channel 400 can be arranged around the periphery of the air nozzle 200 to achieve uniform air outlet from the air outlet channel 400, thereby improving the uniformity and comfort of blowing. The uniform air outlet can also reduce wind noise, making the operation process of the hair dryer quieter and improving the user experience.

[0046] The nozzle assembly of the hair dryer of the embodiment of the utility model includes a base 100, a nozzle 200 and a shell 300, the nozzle 200 is installed on the base 100; the shell 300 is arranged on the base 100, and an installation cavity 101 for installing the nozzle 200 is formed between the shell 300 and the base 100, an air outlet channel 400 is defined between the shell 300 and the nozzle 200, and an air inlet 310 is opened on the side wall of the shell 300, and the air inlet 310 is connected to the air outlet channel 400. By opening an air inlet 310 on the side wall of the shell 300 and forming an air outlet channel 400 between the shell 300 and the nozzle 200, when the air flow is ejected from the air outlet 201 of the nozzle 200, a negative pressure area is formed in the installation cavity 101. Under the action of the negative pressure, the air around the shell 300 will enter the air outlet channel 400 from the air inlet 310 and flow out from the air outlet channel 400, which can supplement the air volume of the nozzle assembly of the hair dryer, thereby increasing the air volume, and can quickly dry the hair, thereby improving efficiency and user experience.

[0047] Exemplarily, the air inlet 310 can also be connected to the inner cavity of the air nozzle 200, so that a portion of the air entering from the air inlet 310 can flow into the air nozzle 200 and flow out from the air outlet 201 of the air nozzle 200, thereby supplementing the air flow and improving the air intake efficiency and performance of the hair dryer.

[0048] According to one embodiment of the present invention, referring to Figure 2 As shown, the air inlet 310 is arranged to be inclined toward the outlet side 401 of the air outlet channel 400 .

[0049] It can be understood that in the present embodiment, by tilting the air inlet 310 toward one side of the air outlet 201 of the air nozzle 200, the flow of air flow can be better guided, and the air flow can be effectively guided to the outlet of the air outlet channel 400, so that the air flow can flow more smoothly to the outlet of the air outlet channel 400, thereby reducing the resistance of the air flow and reducing energy loss, which is more conducive to increasing the air output of the air nozzle assembly of the hair dryer per unit time, thereby improving the efficiency and performance of the hair dryer. In addition, the tilted air inlet 310 can also make it easier for the incoming air to contact and mix with the airflow of the air outlet 201, thereby increasing the contact area between the airflows and further improving the efficiency and uniformity of the airflow.

[0050] In an optional embodiment, the outlet side 401 of the air outlet channel 400 can be arranged side by side with the air outlet 201 of the air nozzle 200, so as to make the air outlet more uniform and improve the comfort of the air outlet.

[0051] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, there are multiple air inlets 310 , and the multiple air inlets 310 are arranged at intervals around the circumference of the housing 300 .

[0052] It is understandable that in this embodiment, by providing multiple air inlets 310, the area of ​​air intake can be increased, the efficiency of the hair dryer inhaling airflow can be improved, and the speed of airflow entering the hair dryer can be accelerated; and the circumferential spacing of multiple air inlets 310 can make the hair dryer inhale the surrounding air more evenly, avoiding the adverse effects caused by uneven local airflow speed, and improving the stability and uniformity of the airflow. In addition, multiple air inlets 310 can reduce the noise and vibration generated when a single air inlet 310 inhales airflow, thereby reducing the working noise and vibration level of the hair dryer, improving the user experience, and also improving the appearance design of the air nozzle assembly of the hair dryer, making it look more beautiful.

[0053] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the air inlet 310 is disposed on one side of the housing 300 close to the air outlet 201 of the air nozzle 200 .

[0054] It can be understood that in this embodiment, setting the air inlet 310 close to the air outlet 201 of the air nozzle 200 can reduce the length of the air outlet channel 400 to a certain extent, thereby reducing the energy loss of the air flow when flowing out of the air outlet channel 400, so that the hair dryer can more effectively utilize the inhaled airflow and more directly guide the incoming airflow to the outlet side 401 of the air outlet channel 400, thereby improving the blowing efficiency.

[0055] According to one embodiment of the present invention, referring to Figure 2 As shown, a guide portion 320 is provided at a position of at least one of the housing 300 and the air nozzle 200 corresponding to the air outlet channel 400 to guide the wind in the air outlet channel 400 .

[0056] In an optional embodiment, a guide portion 320 is provided on the air nozzle 200 at a position corresponding to the air outlet channel 400. The guide portion 320 can guide the wind in the air outlet channel 400 so that it flows toward the outlet side 401 of the air outlet channel 400 more evenly and orderly, which can reduce the turbulence and resistance of the wind flow and improve the efficiency and performance of the hair dryer.

[0057] In another optional embodiment, a guide portion 320 can be set at a position on the inner wall of the shell 300 corresponding to the air outlet channel 400, which can also guide the wind in the air outlet channel 400, reduce the resistance and energy loss during the flow of airflow, and also reduce the noise generated during the operation of the hair dryer to a certain extent.

[0058] In another optional embodiment, a guide portion 320 is provided on both the housing 300 and the air nozzle 200, which together guide the airflow in the air outlet channel 400, thereby more comprehensively optimizing the path of the airflow and ensuring that the airflow is affected as little as possible by resistance and turbulence during the process from the air inlet 310 to the air outlet 201, thereby improving the performance and efficiency of the hair dryer and enhancing the blowing effect.

[0059] According to one embodiment of the present invention, referring to Figure 2 As shown, along the air outlet direction of the air outlet channel 400 , the cross-sectional area of ​​the air outlet channel 400 gradually decreases.

[0060] It is understandable that by gradually reducing the cross-sectional area of ​​the air outlet channel 400 along the air outlet direction, the speed of the airflow in the channel will gradually increase. According to Bernoulli's principle, when the airflow speed increases, the kinetic energy of the airflow also increases, and the pressure will decrease. Therefore, gradually reducing the cross-sectional area of ​​the air outlet 201 can reduce the pressure loss when the airflow passes through the channel and improve the efficiency of the hair dryer. For example, in an optional embodiment, the cross-sectional area of ​​the air outlet channel 400 on the side of the air outlet 201 close to the air nozzle 200 is smaller than the cross-sectional area on the side close to the air inlet 310.

[0061] When the airflow passes through the gradually decreasing air outlet channel 400, the airflow will gradually focus, making the airflow more concentrated and stable, which helps to improve the blowing effect and make the blowing effect more uniform and effective. The overall trumpet-shaped design of the outer shell 300 can make the appearance of the hair dryer more smooth and beautiful.

[0062] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the air nozzle 200 is rotatably mounted on the base 100 , and the air outlet 201 of the air nozzle 200 is provided with a grille component 210 , and the grille component 210 is suitable for driving the air nozzle 200 to rotate relative to the base 100 under the push of airflow.

[0063] The nozzle assembly of the hair dryer in this embodiment can rotate the nozzle 200 relative to the base 100 during use, which effectively expands the blowing area of ​​the hair dryer and can cover a wider area. Due to the increase in the blowing area, the user can dry the hair faster during use, saving time and improving hair drying efficiency.

[0064] It is understandable that the base 100 is used to install and support the air nozzle 200, and the air nozzle 200 can be installed in the base 100 through a bearing 500 or other rotating connection methods, so that the air nozzle 200 can rotate relative to the base 100. Through the rotating connection between the air nozzle 200 and the base 100, the multi-angle adjustment of the air nozzle assembly is realized, so that the blowing direction of the hair dryer can be flexibly adjusted according to user needs, which increases the convenience of use.

[0065] It is understandable that the grille component 210 can guide and disperse the airflow blown out from the air outlet 201, and use the dynamic characteristics of the airflow to realize the automatic rotation of the air nozzle 200. When the airflow passes through the grille component 210, the grille component 210 can generate sufficient rotation torque to drive the air nozzle 200 to rotate.

[0066] It is understandable that the grille plates of the grille component 210 are specially designed to generate sufficient torque when air flows through, so as to drive the air nozzle 200 to rotate. In this embodiment, the grille plates of the grille component 210 are all arranged clockwise and tilted at the air outlet 201 of the air nozzle 200. Of course, the grille plates of the grille component 210 can also be arranged counterclockwise and tilted at the air outlet 201 of the air nozzle 200. The grille plates of the grille component 210 are all arranged tilted in the same direction to help form a rotation torque in the same direction, thereby generating a rotation driving force.

[0067] The utility model does not limit the number of grid plates of the grid component 210 , and the number of grid plates of the grid component 210 may be one or more.

[0068] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the base 100 and the air nozzle 200 are rotatably connected via a bearing 500 , one of the base 100 and the air nozzle 200 is provided with a mounting hole 102 , the outer ring of the bearing 500 is mounted in the mounting hole 102 , and the inner ring of the bearing 500 is connected to the other of the base 100 and the air nozzle 200 .

[0069] It is understandable that the rotational connection between the base 100 and the nozzle 200 through the bearing 500 can effectively reduce the friction between the base 100 and the nozzle 200, reduce energy loss, and help ensure that the nozzle 200 can smoothly rotate relative to the base 100. The bearing 500, as a core component connecting the base 100 and the nozzle 200, can provide smooth rotational movement, so that the nozzle 200 can easily rotate on the base 100 without getting stuck or having bad friction. It can also provide stable support, so that the nozzle 200 remains stable during the rotation process without shaking or instability, ensuring the safe use of the hair dryer.

[0070] In one embodiment, reference Figure 2 and Figure 3 As shown, a cap screw 700 is also included, and the cap screw 700 is used to fix the bearing 500 to the base 100.

[0071] According to one embodiment of the present invention, referring to Figure 2As shown, the housing 300 is provided with a first clamping portion 330 , and the base 100 is provided with a second clamping portion 110 clamped and matched with the first clamping portion 330 , and the first clamping portion 330 and the second clamping portion 110 are clamped.

[0072] It is understandable that in this embodiment, the connection between the housing 300 and the base 100 is achieved by the clamping of the first clamping portion 330 and the second clamping portion 110, which can ensure that the connection between the housing and the base 100 is firm and reliable, not easy to loosen or fall off, and improves good stability. In addition, it is relatively easy to install and disassemble, which is convenient for users to maintain and clean. The clamping structure is easy to process and the manufacturing cost is relatively low.

[0073] It should be noted that the clamping form between the first clamping portion 330 and the second clamping portion 110 includes but is not limited to boss-type clamping, snap-on-type clamping or locking pin-type clamping, and can be designed according to specific needs, which is not specifically limited in this embodiment.

[0074] In other embodiments, the housing 300 may also be integrally formed with the base 100 to simplify the manufacturing process and assembly process and improve the structural strength.

[0075] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, it also includes a magnetic component 600, which is arranged on the side of the base 100 facing away from the air outlet 201. It can be understood that the magnetic component 600 makes the connection between the base 100 and other related components or surfaces more convenient. By utilizing the principle of magnetic adsorption, the base 100 can be easily fixed without using traditional fixing methods such as screws and buckles. Similarly, disassembly becomes simple and fast, and separation can be achieved by simply overcoming the magnetic force, which greatly improves the convenience of operation.

[0076] According to an embodiment of the utility model, a storage component is further included, which can be arranged corresponding to the grille component 210, and the storage component is used to store hair care products. It is understandable that when using a hair dryer for hair styling, users often need to use hair care products, such as styling spray, hair care essential oil, etc. By arranging the storage component on the grille component 210, users can conveniently use these hair care products during the hair drying process, thereby greatly improving the convenience of use.

[0077] An embodiment of the second aspect of the utility model provides a hair dryer, comprising the nozzle assembly of the hair dryer of any of the above embodiments.

[0078] In one embodiment, the hair dryer includes a body, and the nozzle assembly is detachably mounted at the air outlet position of the body. Specifically, the nozzle assembly can be detachably connected to the body by magnetic attraction. Of course, the nozzle assembly can also be detachably connected to the body by other methods such as snap connection, screw connection, etc., and the utility model does not specifically limit this.

[0079] In one embodiment, at least one of the body and the base 100 is provided with a magnetic component 600, and the other is provided with a metal part or another magnetic component 600. When the base 100 is installed to the body, the magnetic force can firmly connect the magnetic component 600 and the metal part or another magnetic component 600 together.

[0080] In one embodiment, the nozzle assembly further includes a bottom cover 800 , and the bottom cover 800 is used to install the magnetic attraction component 600 of the nozzle assembly on the bottom of the base 100 .

[0081] It can be understood that if the nozzle assembly of the hair dryer has the beneficial effects of the above embodiments, then the hair dryer correspondingly has the beneficial effects of the above embodiments. The specific implementation method thereof may refer to the above embodiments, and will not be described in detail in this application.

[0082] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not deviate from the spirit and scope of the technical solutions of the present invention, and should be included in the protection scope of the present invention.
