Abstract
Description
Technical Field
[0001] The present invention relates to the field of hair dryer attachments and electric hair dryers, and particularly to hair dryer nozzles and the hair dryers thereof.
Background Art
[0002] Hair dryers are common personal care electrical appliances, widely applied in households and professional beauty salons, and are used to quickly dry hair or style it. Conventional hair dryers usually have one or more fixed air outlets, and the hair is dried by the wind force. However, the designs of these hair dryer nozzles are relatively simple and often lack targeted airflow control and personalized styling functions.
[0003] In the prior art, the design of hair dryer nozzles usually includes one or more air outlets, but there are some limitations in these designs. First, the fixed air outlets cannot provide multi-directional wind, which limits the wind force distribution and styling flexibility. Second, the airflow of conventional nozzles is often overly concentrated, causing the hair to receive uneven heat, which may have an adverse effect on the styling effect and hair health. Also, the adhesion between the nozzle and the user's head is generally low, which not only affects the wind transmission efficiency but may also cause discomfort to the user.
[0004] To solve the above problems, some manufacturers have tried to control the hair dryer's blowing by installing a complex electronic control structure inside the nozzle, but this type of nozzle increases the cost and maintenance complexity. Also, these designs are still insufficient in terms of ease of use and may not be able to meet the personalized needs of various users for wind force and styling effects.
Summary of the Invention
Problems to be Solved by the Invention
[0005] In light of the limitations of conventional technology, the present invention aims to provide a novel hair dryer nozzle that, through an innovative design, achieves more uniform and controllable airflow output, as well as providing a superior user experience and styling effect.
[0006] The present invention aims to provide a hair dryer nozzle and the hair dryer thereof, and to solve at least one of the technical problems that exist in the prior art. [Means for solving the problem]

[0008] Furthermore, the discharge unit includes an outlet, an inlet, and a wind-restricting structure, the wind-restricting structure being connected between the outlet and the inlet, the wind-restricting structure including a first windbreak slope and a second windbreak slope, the first windbreak slope being provided corresponding to the vertical position of the second windbreak slope, the first windbreak slope being provided in a horizontal direction with respect to the airflow direction, the surface area of the first windbreak slope being larger than the surface area of the second windbreak slope, and the inlet and outlet being provided offset vertically.
[0009] Furthermore, in the horizontal direction with respect to the airflow direction, the cross-sectional area corresponding to the first windbreak slope coincides with the area of the intake port, and the cross-sectional area of the second windbreak slope coincides with the area of the outlet port.
[0010] Furthermore, in the direction perpendicular to the airflow direction, the cross-sectional area corresponding to the first windbreak slope coincides with the cross-sectional area of the second windbreak slope.
[0011] Furthermore, at least one comb-like tooth is provided on the airflow panel between adjacent air outlet units and adjacent position limiting members, and the material of the comb-like tooth is soft plastic or metal.
[0012] Furthermore, the nozzle further includes an outer case and an inner case, wherein a mounting base for connection to the outlet of a hair dryer is provided inside the outer case, and a ventilation gap communicating with a ventilation cavity is provided between the mounting base and the outer case, the inner case is fitted inside the outer case, the air direction panel is supported in contact with an opening in the inner case, the air direction panel is fixed and connected to the inner case by fastening bolts or snaps, the fastening bolts are located inside the outer case.
[0013] Furthermore, the outer contour of the outer case has a shape that gradually changes into an arc shape and increases in size from the inlet to the outlet in the direction of airflow.
[0014] Furthermore, the mounting base is located inside the airflow passage, and the mounting base has a shape that gradually transitions into an arc from the inlet to the outlet in the direction of airflow.
[0015] Furthermore, the surfaces of the multiple densely packed comb teeth are all C-shaped arc surfaces that are concave inward.
[0016] A hair dryer, including the hair dryer nozzle described above. [Effects of the Invention]
[0017] The beneficial effects of this invention are as follows:
[0018] The hair dryer nozzle has a partition plate inside the air passage that divides the air passage into multiple independent air cavities. A partition plate is also provided in the middle of the air passage to divide the internal air passage into multiple cavities, which allows the high-speed air generated inside the hair dryer to be transmitted and divided almost evenly within the nozzle. Subsequently, each nozzle outlet can blow out a nearly equal and uniform amount of air. By inserting the comb teeth into the hair, the air does not directly hit the user's head, and the siphon effect directs the hair along the air direction panel, blowing air almost vertically downward along the hair for more efficient combing. Because the hair is combed by blowing air along the air direction panel, this nozzle can be easily applied to comb both dry and wet hair.
[0019] The discharge array is partitioned into multiple densely packed discharge units by providing multiple position limiting members, and the air direction panel between adjacent discharge arrays is provided with multiple densely packed comb teeth. By combining the multiple discharge arrays and the densely packed comb tooth structure of this air blower nozzle structure, when the user combs along their straight hair, the comb teeth straighten the hair, and because the multiple densely packed arrays blow out a nearly equal and uniform amount of air, the hair can be dried and styled more smoothly and straightly.
[0020] The surface of the airflow panel is a C-shaped arc that is recessed inward, allowing it to conform to the shape of the human head. This improves the contact between the nozzle's airflow panel and the user's head, thereby enhancing user comfort during use.
[0021] This nozzle redirects the airflow blown out from a hair dryer by a wind restriction structure that bends the airflow by approximately 90 degrees and blows it obliquely. As is clear from the figure, the airflow is blown out obliquely to the outside near the air outlet, and since there is a pressure difference in the airflow between the wind direction panels among the plurality of blowout arrays, the siphon effect occurs, and the corresponding hair is adsorbed to the wind direction panel by the negative pressure region and blown downward along the center of gravity of the hair, and the hair is arranged in combination with the comb teeth. The wind of a conventional hair dryer forms a 90-degree right angle with the hair, so the hair becomes frizzy and is likely to cause split ends and hair disarray. On the other hand, the nozzle of the present invention combs the hair along the hair, and the airflow due to the blown siphon action is blown downward in a direction parallel to the hair, smoothly arranging the hair, preventing split ends of the hair, and drying the hair more easily. By inserting the comb teeth into the inside of the hair, the surface area where the wind direction panel contacts the hair is increased, the heat conversion rate is increased, and the hair drying rate is increased.
[0022] Also, additional aspects and advantages of the present invention are partly described in the following description, partly will become apparent from the following description, or can be understood by the implementation of the present invention.

The term "and / or" as used herein includes any combination of one or more related enumerated items.
[0027] In this disclosure, various elements may be described using terms such as 1st, 2nd, 3rd, etc., but it should be understood that these elements should not be limited to these terms. These terms are merely used to distinguish elements of the same type. For example, without departing from the scope of this disclosure, 1st element may be called 2nd element, and similarly, 2nd element may be called 1st element.
[0028] Referring to Figures 1 to 9, in some embodiments, the present invention discloses a hair dryer nozzle that includes the following:
[0029] Referring to the airflow passage 100 shown in Figures 1 to 4, a partition plate 110 is provided within the airflow passage 100 to divide the airflow passage 100 into a plurality of independent airflow cavities 120. A partition plate is provided at an intermediate position inside the airflow passage 100 to equally divide the internal airflow passage 100 into two cavities. This is used to transmit the high-speed airflow generated inside the hair dryer, and the air is divided almost evenly inside the nozzle, without becoming turbulent in the space of a single cavity, effectively increasing the airflow velocity at the outlet and reducing noise. Subsequently, each nozzle outlet can blow out an almost equal and uniform amount of air, directing the airflow along the airflow direction panel 200 to comb the hair.
[0030] Referring to Figure 1, a wind direction panel 200 is provided at the end of the airflow direction. The outer contour shape of the wind direction panel 200 is not a planar structure. Multiple discharge arrays 300 are provided on the wind direction panel 200 corresponding to the airflow cavity 120. Multiple position limiting members 310 are provided on the discharge arrays 300 to partition multiple densely packed discharge units 320. Multiple densely packed comb teeth 330 are provided on the wind direction panel 200 between adjacent discharge arrays 300. By combining the multiple discharge arrays and densely packed comb tooth structure of this airflow nozzle structure, when the user combs their hair along straight hair, the comb teeth straighten the hair, and the multiple densely packed arrays blow out a nearly equal and uniform amount of air, thus drying the hair and making it smoother and straighter.
[0031] Continuing to refer to Figure 2, the surface of the airflow panel 200 is a C-shaped arc that is recessed inward, allowing it to conform to the shape of a human head, increasing the contact area between the airflow panel and the hair, improving the close contact between the nozzle's airflow panel and the user's head, and enhancing the user's comfort during use.
[0032] Referring to Figure 5, the discharge unit 320 includes an outlet 321, an inlet 322, and a wind-restricting structure 400, the wind-restricting structure 400 being connected between the outlet 321 and the inlet 322, the wind-restricting structure 400 including a first windbreak slope 410 and a second windbreak slope 420, the first windbreak slope 410 being provided corresponding to the vertical position of the second windbreak slope 420, the first windbreak slope 410 being provided horizontally with respect to the airflow direction, the surface area of the first windbreak slope 410 being larger than the surface area of the second windbreak slope 420, and the inlet 322 and outlet 321 being provided with a vertical offset. By offsetting the intake and outlet, the air blown from the hair dryer under positive pressure passes through the air passage 100, then the positive pressure air passes through the discharge array 300, which has a smaller overall cross-sectional area. The high-speed positive pressure air from the discharge array 300, the air-restricting structure 400, and the outlet 321 passes through the air-restricting structure, which is bent and offset in position, and is then blown out at a higher speed, supplying airflow to each individual strand of hair as much as possible when straightening hair with a straightener. The multi-layered air blowing unit creates a synergistic effect, resulting in higher blowing efficiency and beneficially reducing the time it takes to dry hair.
[0033] Referring to Figure 9, it can be seen that the airflow blown out from the hair dryer (indicated by the arrow) is redirected by the airflow limiting structure 400, which is bent at approximately 90 degrees, and blown out at an angle. In the drawing, the airflow is blown out at an angle to the outside near the outlet 321, and because there is a pressure difference in the airflow between the multiple outlet arrays 300, the airflow direction panel in the drawing is a negative pressure region, meaning that a siphon effect occurs, and the corresponding hair is attracted to the airflow direction panel by the negative pressure region and blown downward along the center of gravity of the hair, and in combination with the comb teeth the hair is styled. Conventional hair dryers blow air at a 90-degree right angle to the hair, which can make the hair frizzy and prone to split ends and unruly hair. On the other hand, the nozzle of the present invention combs the hair along its contours, and the siphon-driven airflow is blown downward in a direction parallel to the hair, smoothing the hair, preventing split ends, drying the hair more easily, increasing the heat conversion rate, and improving the drying rate of the hair.
[0034] Referring to Figure 5, in the horizontal direction with respect to the airflow direction, the cross-sectional area corresponding to the first windbreak slope 410 coincides with the area of the intake port 322, and the cross-sectional area of the second windbreak slope 420 coincides with the area of the outlet port 321. In the vertical direction with respect to the airflow direction, the cross-sectional area corresponding to the first windbreak slope 410 coincides with the cross-sectional area of the second windbreak slope 420. As is clear from the figure, the airflow from the hair dryer is divided almost in half as it passes through the airflow cavity 120, then passes through the densely packed intake ports 322 and the bent, staggered airflow limiting structures 400, after which the high-speed airflow is accelerated and finally discharged from the outlet port 321, acting uniformly on human hair. Referring to Figure 9, at the outlet, the airflow is redirected to a downward direction by the passage formed by the cooperation of the first windbreak slope 410 and the second windbreak slope 420.
[0035] Referring to Figure 6, at least one comb tooth 330 is provided on the airflow panel 200 between the adjacent air outlet unit 320 and the adjacent position limiting member 310, and the material of the comb tooth 330 is soft plastic or metal. The comb tooth provided correspondingly below the air outlet unit 320 works together to style the hair, thereby enhancing the hair-combing function of the hair dryer nozzle.
[0036] Referring to Figures 3 and 4, the configuration further includes an outer case 500 and an inner case 600, wherein the outer case 500 is provided with a mounting base 510 for connection to the hair dryer outlet 321, and between the mounting base 510 and the outer case 500 are air gaps communicating with the air blower cavity 120, the inner case 600 is fitted inside the outer case 500, the air direction panel 200 is supported in contact with an opening in the inner case 600, and the air direction panel 200 is fixed and connected to the inner case 600 by fastening bolts or snaps, the fastening bolts are located inside the outer case 500. The air direction panel is fitted into the inner case and fastened with bolts, but since the bolts are housed inside the outer case, the bolt fasteners are not exposed throughout the hair dryer nozzle, resulting in a more aesthetically pleasing overall appearance.
[0037] Referring to Figure 2, the outer contour of the outer case 500 has a shape that gradually increases in size while transitioning into an arc from the inlet to the outlet in the airflow direction. A hair dryer nozzle with this shape can be easily grasped by the user and used to comb hair independently, and does not need to be used in combination with a hair dryer.
[0038] Referring to Figure 4, the mounting base 510 is located inside the air passage 100, and the mounting base 510 has a shape that gradually transitions into an arc from the inlet to the outlet in the direction of airflow. As a result, when air enters the air cavity 120 and hits the arc-shaped mounting base 510, it does not encounter resistance, and the airflow within the cavity is accelerated.
[0039] Referring to Figure 2, the surfaces of the multiple densely packed comb teeth 330 are all C-shaped arc surfaces that are concave inward, so that the entire comb teeth conform to the shape of a human head and are suitable for combing hair.
[0040] Based on the above, the hair dryer nozzle disclosed in this invention can be attached to the outlet of a hair dryer and used. The above is merely a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments. Any modifications, substitutions with equivalents, improvements, etc., made within the spirit and principles of this disclosure, as long as the technical effects of the present invention are achieved by the same means, should be included within the scope of protection of this disclosure. All of these should fall within the scope of protection of the present invention. Within the scope of protection of the present invention, its technical solutions and / or embodiments can be modified and changed in various ways.
