Description

A hair dryer nozzle and its hair dryer Technical Field

[0001] This invention relates to the field of hair dryer accessories and electrical hair dryers, and particularly to a hair dryer nozzle and its hair dryer. Background Technology

[0002] Hair dryers are common personal care appliances, widely used in homes and professional hair salons for quickly drying and styling hair. Traditional hair dryers typically have one or more fixed-direction air outlets that dry hair using airflow. However, these hair dryers often have simple nozzle designs, lacking targeted airflow control and personalized styling features.

[0003] In existing technologies, hair dryer nozzles typically include one or more air outlets, but these designs have several limitations. First, fixed air outlets cannot provide multi-directional airflow, limiting airflow distribution and styling flexibility. Second, the airflow from traditional nozzles is often too concentrated, potentially leading to uneven heating of the hair, affecting styling results and hair health. Furthermore, the nozzle's fit to the user's head is usually not ideal, which not only affects airflow efficiency but may also cause user discomfort.

[0004] To address these issues, some manufacturers have attempted to control the airflow of hair dryers by incorporating complex electronic control structures within the nozzles. However, these nozzles increase costs and maintenance complexity. Furthermore, these designs may not be user-friendly enough to meet the individualized needs of different users regarding airflow power and styling effects.

[0005] In view of the limitations of existing technology, the present invention provides a novel hair dryer nozzle, which aims to achieve more uniform and controllable airflow output through innovative design, while providing a better user experience and styling effect. Summary of the Invention

[0006] This invention provides a hair dryer nozzle and a hair dryer thereof, aiming to solve at least one of the technical problems existing in the prior art.

[0007] The technical solution of the present invention is a hair dryer nozzle, which includes: an air supply channel, wherein a partition plate is provided in the air supply channel to divide the air supply channel into multiple independent air supply cavities, and an air direction panel is provided at the end in the air delivery direction. The air direction panel is provided with multiple air outlet arrays corresponding to the air supply cavities. The air outlet arrays are divided into multiple dense air outlet units by multiple limiting members. The air direction panels between adjacent air outlet arrays are provided with multiple dense comb teeth. The surface of the air direction panel is a concave C-shaped arc surface to allow it to match the shape of the human head.

[0008] Furthermore, the air outlet unit includes an air outlet, an air inlet, and a wind limiting structure. The wind limiting structure is connected between the air outlet and the air inlet. The wind limiting structure includes a first wind-blocking slope and a second wind-blocking slope. The first wind-blocking slope is positioned above and below the second wind-blocking slope, respectively. The first wind-blocking slope is positioned in the horizontal direction of the wind direction. The surface area of ​​the first wind-blocking slope is larger than the surface area of ​​the second wind-blocking slope. The air inlet and the air outlet are staggered vertically.

[0009] Furthermore, in the horizontal direction of wind transport, the cross-sectional area of ​​the first windbreak slope is the same as the area of ​​the air inlet, and the cross-sectional area of ​​the second windbreak slope is the same as the area of ​​the air outlet.

[0010] Furthermore, in the vertical direction of wind transport, the cross-sectional area of ​​the first windbreak slope is the same as the cross-sectional area of ​​the second windbreak slope.

[0011] Furthermore, at least one comb tooth is provided on the air direction panel between adjacent air outlet units and adjacent limiting members, and the comb tooth is made of soft plastic or metal.

[0012] Furthermore, it also includes: an outer shell, wherein an installation seat for connecting the air outlet of the blower is provided inside the outer shell, and an air supply gap is provided between the installation seat and the outer shell to communicate with the air supply cavity; an inner shell sleeved inside the outer shell, wherein the air direction panel contacts and supports the opening of the inner shell, wherein the air direction panel is fixedly connected to the inner shell by fastening bolts or buckles, and the fastening bolts are located inside the outer shell.

[0013] Furthermore, the outer contour shape of the outer shell gradually increases in size from the inlet to the outlet in the wind conveying direction with a rounded transition.

[0014] Furthermore, the mounting base is located inside the air supply channel, and the shape of the mounting base gradually transitions to an arc from the inlet to the outlet in the direction of air delivery.

[0015] Furthermore, the surfaces of the multiple densely packed comb teeth are all concave C-shaped arc surfaces.

[0016] A hair dryer, comprising the aforementioned hair dryer nozzle.

[0017] The beneficial effects of this invention include:

[0018] The air delivery channel inside the hair dryer nozzle is divided into multiple independent air delivery chambers by a partition plate. This partition plate, located in the middle of the air delivery channel, divides the internal air delivery channel into multiple chambers to transmit the high-speed airflow generated within the hair dryer. This allows the airflow to be nearly equally divided within the nozzle, enabling the nozzle outlet to output almost equal and uniform airflow. After the comb teeth insert into the hair, the airflow does not blow directly onto the user's head. Instead, it uses a siphon principle to make the hair adhere to the airflow panel and blow-dry and comb it almost vertically downwards for more efficient hair styling. Because the hair is close to the airflow panel during blow-drying and combing, this nozzle is convenient for styling both dry and wet hair.

[0019] The air outlet array is divided into multiple dense air outlet units by setting multiple limiting components. The air direction panel between adjacent air outlet arrays is provided with multiple dense comb teeth. The multiple air outlet arrays of this air nozzle structure, combined with the dense comb tooth structure, allow the comb teeth to straighten the hair when the user combs the hair. In addition, the multiple dense arrays output almost equal and almost uniform airflow, which dries the hair and straightens it more smoothly.

[0020] The air direction panel has a concave C-shaped arc surface to allow it to match the shape of the human head, so that the air direction panel on the nozzle fits the user's head very closely, which can improve the user's comfort.

[0021] This nozzle directs the airflow from the hairdryer through a near 90-degree bend in a wind-limiting structure, tilting it downwards. As shown in the diagram, the airflow is angled near the outlet, and a pressure difference between the multiple airflow arrays creates a siphon effect on the airflow panel. Hair is drawn to the airflow panel by the negative pressure area and blown downwards along the hair's center of gravity, combined with the comb-like teeth to smooth the hair. In contrast, traditional hairdryers create a 90-degree angle with the hair, resulting in frizzy, split, and unruly hair. This nozzle, a hair-smoothing comb, uses a siphon-like airflow that blows downwards parallel to the hair, smoothing it, preventing split ends, and making it easier to dry. The comb teeth penetrate the hair shaft, increasing the surface area of ​​the airflow panel in contact with the hair, thus improving heat conversion and drying efficiency.

[0022] Furthermore, additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Furthermore, the descriptions of "upper," "lower," "left," "right," "top," and "bottom" used in this invention are only relative to the relative positional relationships of the various components of the invention in the accompanying drawings.

[0034] Furthermore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and not for limiting the invention. The term "and / or" as used herein includes any combination of one or more of the associated listed items.

[0035] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0036] Referring to Figures 1 to 9, in some embodiments, the present invention discloses a hair dryer nozzle, which includes:

[0037] Referring to the air supply channel 100 shown in Figures 1 to 4, the air supply channel 100 is provided with a partition plate 110 to divide the air supply channel 100 into multiple independent air supply chambers 120. The partition plate is located in the middle of the air supply channel 100 to divide the internal air supply channel 100 into two equal chambers, which are used to transmit the high-speed air generated in the hair dryer. This allows the air to be almost equally divided inside the nozzle, and the air will not wander around in the space of a single chamber. This effectively increases the air velocity at the outlet and reduces noise. Then, the air outlet of the nozzle can output almost equal and almost uniform air volume, so that the hair is blown and combed along the air direction panel 200.

[0038] Referring to Figure 1, a wind direction panel 200 is provided at the end of the wind direction conveying direction. The outer contour shape of the wind direction panel 200 is not a planar structure. The wind direction panel 200 is provided with multiple air outlet arrays 300 on the air supply cavity 120. The air outlet arrays 300 are divided into multiple dense air outlet units 320 by multiple limiting members 310. The wind direction panels 200 between adjacent air outlet arrays 300 are provided with multiple dense comb teeth 330. The multiple air outlet arrays of this air supply nozzle structure, combined with the dense comb tooth structure, allow the comb teeth to straighten the hair when the user combs the hair. In addition, the multiple dense arrays output almost equal and almost uniform airflow, which can straighten the hair more smoothly while drying it.

[0039] Referring to Figure 2, the surface of the airflow panel 200 is a concave C-shaped arc surface to allow it to match the shape of the human head, increasing the area of ​​the airflow panel in contact with the hair, and making the airflow panel on the nozzle fit the user's head very closely, which can improve the user's comfort.

[0040] Referring to Figure 5, the air outlet unit 320 includes an air outlet 321, an air inlet 322, and a wind limiting structure 400. The wind limiting structure 400 connects the air outlet 321 and the air inlet 322. The wind limiting structure 400 includes a first wind-blocking inclined surface 410 and a second wind-blocking inclined surface 420. The first wind-blocking inclined surface 410 is positioned above and below the second wind-blocking inclined surface 420. The first wind-blocking inclined surface 410 is positioned in the horizontal direction of the wind direction. The surface area of ​​the first wind-blocking inclined surface 410 is larger than the surface area of ​​the second wind-blocking inclined surface 420. The air inlet 322 and the air outlet 321 are staggered vertically. The staggered arrangement between the air inlet and outlet allows the positive pressure airflow from the hair dryer's positive pressure input air delivery channel 100 to pass through the smaller cross-sectional area of ​​the air outlet array 300. The high-speed positive pressure airflow from the air outlet array 300, the air limiting structure 400, and the air outlet 321 is then output at an even higher speed after passing through the staggered and bent air limiting structure. This maximizes the drying of each strand of hair while it's being straightened with a straightener. The multi-layered airflow unit creates a synergistic effect, resulting in higher airflow efficiency and saving drying time.

[0041] Referring to Figure 9, the airflow from the hairdryer (as indicated by the arrow) is redirected and output at an angle by a near 90-degree bend in the air-limiting structure 400. It can be seen that the airflow is angled and output to the outside near the air outlet 321. Due to the pressure difference of the airflow on the airflow direction panel between the multiple air outlet arrays 300, the airflow direction panel in the figure is a negative pressure area, i.e., a siphon effect occurs. The corresponding hair is attracted to the airflow direction panel by the negative pressure area and then blown downwards along the center of gravity of the hair. Combined with the comb teeth, this smooths the hair. In contrast, the airflow from a traditional hairdryer forms a 90-degree angle with the hair, resulting in a frizzy, split, and messy appearance. The airflow from the nozzle of this invention, using a hair comb based on the siphon principle, blows downwards parallel to the hair, smoothing the hair, preventing split ends, making the hair dry more easily, and improving heat conversion rate and hair drying rate.

[0042] Referring to Figure 5, in the horizontal direction of airflow, the cross-sectional area of ​​the first wind-blocking slope 410 is the same as the area of ​​the air inlet 322, and the cross-sectional area of ​​the second wind-blocking slope 420 is the same as the area of ​​the air outlet 321. In the vertical direction of airflow, the cross-sectional area of ​​the first wind-blocking slope 410 is the same as the cross-sectional area of ​​the second wind-blocking slope 420. It can be seen that the air from the hair dryer is almost split in half after passing through the air delivery cavity 120, then through the dense array of air inlets 322, and the bent, staggered air-limiting structure 400, before the high-speed airflow is accelerated and finally delivered from the air outlet 321, acting evenly on the hair. Referring to Figure 9, the air outlet changes the downward direction of the airflow through the channel formed by the cooperation of the first wind-blocking slope 410 and the second wind-blocking slope 420.

[0043] Referring to Figure 6, at least one comb tooth 330 is provided on the airflow panel 200 between adjacent air outlet units 320 and adjacent limiting members 310. The comb tooth 330 is made of soft plastic or metal. The comb tooth corresponding to the lower part of the air outlet unit 320 is designed to straighten the hair and enhance the hair combing function of the hair dryer nozzle.

[0044] Referring to Figures 3 and 4, the device also includes an outer casing 500. Inside the outer casing 500 is a mounting base 510 for connecting the air outlet 321 of the hair dryer. An air supply gap is provided between the mounting base 510 and the outer casing 500, communicating with the air supply cavity 120. An inner casing 600 is fitted inside the outer casing 500. The air direction panel 200 contacts and supports the opening of the inner casing 600. The air direction panel 200 is fixedly connected to the inner casing 600 by fastening bolts or clips, with the fastening bolts located inside the outer casing 500. The air direction panel is fastened to the inner casing with bolts, but the bolts are housed inside the outer casing, so that the entire hair dryer nozzle does not expose the bolt fasteners, resulting in a more aesthetically pleasing overall appearance.

[0045] Referring to Figure 2, the outer contour of the outer casing 500 gradually increases in size from the inlet to the outlet in the air delivery direction, creating a rounded transition. This design allows the hair dryer nozzle to be easily held and used independently for combing hair, without needing to be used in conjunction with a hair dryer.

[0046] Referring to Figure 4, the mounting base 510 is located inside the air supply channel 100. The shape of the mounting base 510 gradually transitions to a rounded shape from the inlet to the outlet in the air delivery direction, so that the air entering the air supply cavity 120 encounters no resistance when it meets the rounded mounting base 510, thus accelerating the air supply to the cavity.

[0047] Referring to Figure 2, the surfaces of the multiple densely packed comb teeth 330 are all concave C-shaped arc surfaces, making the entire comb teeth suitable for the human head shape when combing hair.

[0048] In summary, the hair dryer nozzle disclosed in this invention can be assembled and used with the air outlet of a hair dryer. The above description is merely a preferred embodiment of this invention, and the invention is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effects, should be included within the scope of protection of this invention.
