Description

Technical Field

[0001] This utility model relates to a hair care device and its accessories, and more particularly to a hair care device and its accessories that can guide the direction of airflow. Background Technology

[0002] Hair styling tools such as hair dryers typically rely on attachments like nozzles or diffusers to guide airflow for styling. However, these traditional attachments lack the ability to simultaneously make physical contact with the hair, such as by combing or smoothing it, which can enhance styling results. Achieving smooth, frizz-free hair usually requires the use of multiple tools, increasing the time required and increasing the potential for heat damage.

[0003] An improved attachment is needed to increase the efficiency of smoothing and styling hair. Utility Model Content

[0004] This invention provides an improved accessory for a hair care appliance and a hair care appliance with the accessory.

[0005] The hair care appliance can be any hair care appliance that uses airflow to dry, care for, or style the hair, such as a hair dryer, straightener, or styling comb.

[0006] This accessory can be detachably or non-detachably connected to hair care devices. The accessory includes:

[0007] An air inlet is used to receive airflow from the hair care appliance, which enters the accessory in a first direction through the air inlet.

[0008] The air outlet is in fluid communication with the air inlet.

[0009] An air guide channel extending between an air inlet and an air outlet is configured to guide airflow from a first direction to a second direction and out of the air outlet in the second direction, wherein the angle between the first direction and the second direction is between 15 and 90 degrees, preferably between 45 and 90 degrees.

[0010] The accessory includes an extension that extends downstream from the bottom of the air outlet, and the surface of the extension facing the airflow is a generally flat surface.

[0011] Since the extension is located downstream of the bottom of the air outlet, the airflow blown out of the air outlet can be blocked by the extension and not diffused outward. When the hair approaches the accessory to receive the airflow, the airflow mainly flows between the extension and the hair. Due to the Bernoulli effect, a pressure difference is formed between the airflow and the generally flat surface, which can guide at least part of the airflow blown out of the air outlet to continue flowing along the generally flat surface of the extension facing the airflow. This will attract some hair to the surface, thus making the hair smooth.

[0012] The air guide channel includes a bottom and a top. Optionally, the extension extends in the same direction as the second direction, that is, in the same direction as the bottom of the air guide channel near the air outlet. This allows the airflow to remain in the second direction and continue to flow along the extension, reducing airflow loss.

[0013] Optionally, the extension extends at an angle further deviating from the first direction relative to the second direction; that is, the direction of extension forms an angle with the second direction, which is further deviated from the first direction relative to the second direction. In other words, the extension extends downstream from the air outlet along an angle away from the first direction relative to the bottom of the air guide channel near the air outlet. Because the extension extends upward at an angle further deviating from the first direction relative to the second direction, the air outlet area is increased, allowing the airflow to contact the hair at a greater angle.

[0014] Optionally, the angle of the extension relative to the bottom of the air guide channel near the air outlet is adjustable. Because the angle is adjustable, the extension can be chosen to extend in the same direction as the second direction, or in a third direction at an angle to the second direction, providing greater flexibility and allowing the angle to be selected as needed.

[0015] Optionally, the extension includes multiple comb teeth that extend outward from a flat surface of the extension facing the airflow. The arrangement of multiple comb teeth helps to secure and detangle knotted hair, making it smoother.

[0016] Optionally, the top of the air guide channel near the air outlet includes a wave structure. The wave structure at the top of the air guide channel matches the left and right gaps of the comb teeth, which can improve airflow conduction efficiency, resulting in better hair care and higher efficiency.

[0017] Optionally, the generally flat surface of the extension facing the airflow includes at least one of the following structures: multiple small protrusions, multiple small grooves, or a slightly wavy surface. These protrusions or wavy surfaces allow hair to adhere better to the generally flat surface. These minute protrusions, grooves, or wavy surfaces are small enough relative to the area of ​​the flat surface of the extension that they do not affect the fact that the plane as a whole remains a flat surface. A flat surface as used herein means that the plane as a whole is not an arc-shaped curved surface, nor a bent surface.

[0018] Optionally, the top outer surface of the air duct near the air outlet includes multiple comb teeth extending outward from this top outer surface. These comb teeth can also help secure and detangle hair, making it smoother. Attached Figure Description

[0027] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it should be understood that the drawings are only used to illustrate the present invention and do not constitute a limitation on the present invention.

[0028] refer to Figures 1 to 3 According to a first embodiment of the present invention, an accessory 10 for a hair care appliance, such as a hair dryer (not shown), includes an air inlet 101 for receiving airflow from the hair care appliance, the airflow entering the accessory 10 through the air inlet 101 in a first direction F1. The accessory also includes an air outlet 102, which is in fluid communication with the air inlet 101. An air guide channel 103 extending between the air inlet 101 and the air outlet 102 is also included, the air guide channel 103 being configured to guide the airflow from the first direction F1 to a second direction F2, and to exit from the air outlet in the second direction F2. The angle between the first and second directions is between 15 and 90 degrees, preferably between 45 and 90 degrees. It can be understood that when the first direction is horizontal, the larger the angle of the second direction, the closer the direction of the airflow is to the vertical direction, that is, the closer it is to the direction in which the hair naturally falls, and therefore the airflow has a better smoothing effect on the hair when it is blown onto it.

[0029] Annex 10 according to this embodiment includes an extension 104 that extends downstream from the bottom 105 of the air outlet 102 to guide at least part of the airflow blown out of the air outlet to continue flowing along the generally flat surface 107 of the extension facing the airflow.

[0030] Because of the extension 104, which includes a generally flat surface 107, the airflow from the outlet 102 is blocked from diffusing outward by the extension 104 and continues to blow between the extension 104 and the hair (when the user brings the hair close to the outlet to receive the airflow). Due to the Bernoulli effect, a pressure difference is created between the airflow and the flat surface, which will attract some of the hair to the flat surface, making the hair smoother.

[0031] The air guide channel 103 includes a bottom 111 and a top 112, wherein the second direction is approximately determined by the extension direction of the air guide channel near the air outlet. That is, the extension directions of the bottom inner wall 113 and the top inner wall 114 of the extension channel near the air outlet essentially determine the second direction of the airflow. The extension 104 extends in a direction consistent with the second direction F2; that is, the extension 104 continues downstream from the air outlet along the extension direction of the air guide channel near the air outlet. This allows the airflow to remain in the second direction F2 and continue flowing along the extension, reducing airflow loss.

[0032] Figure 4 and Figure 5 Annex 40 is shown according to another embodiment of the present invention, and Figures 1-3 Similar parts of the embodiment will not be described again. The extension 404 extends from the air outlet along a third direction F3 at an angle to the second direction F2. This angle is further away from the first direction than the second direction, meaning the angle between the third direction and the first direction is greater than the angle between the second direction and the first direction. By setting the extension 404 to extend along a third direction at an angle further away from the first direction F1 than the second direction F2, the air outlet area can be increased, allowing the airflow to contact the hair at a larger angle.

[0033] According to another embodiment of the present invention, the extension can also be configured to have an adjustable angle relative to the bottom of the air guide channel near the air outlet. For example, the connection between the extension and the bottom of the air outlet can be configured as a rotatable connection with several settings. The specific connection structure is not the focus of this invention, and those skilled in the art can choose different structures according to their needs, which will not be elaborated here.

[0034] Optionally, the extension 404 may include a plurality of comb teeth 405 extending outward from the airflow-facing flat surface 407 of the extension to help secure and untangle knotted hair, making the hair smoother.

[0035] Optionally, the top 414 of the air guide channel near the air outlet 402 includes a wave structure. The width of this wave structure is consistent with the left and right gaps of each comb tooth, which can improve air conduction efficiency and make the hair look better.

[0036] like Figure 6 In another embodiment of the attachment 60 shown, the generally flat surface 607 of the extension 604 facing the airflow includes a plurality of small protrusions 608 and a plurality of small grooves 609. The structure of the multiple small protrusions and grooves can better allow the hair to adhere to the surface of the extension.

[0037] like Figure 7 The accessory 70 of another embodiment shown has an extension 704 facing the airflow and a generally flat surface 707 including a plurality of small waves 708.

[0038] Understandably, although there are multiple bumps and grooves, or small waves, planes 607 and 707 are still flat surfaces overall, not curved or folded surfaces.

[0039] like Figure 8 In another embodiment of the accessory 80 shown, the top outer surface 814 of the air duct near the air outlet includes a plurality of comb teeth 808 extending outward from the top outer surface. These comb teeth can also help secure and detangle knotted hair, making it smoother.

[0040] The accessory according to this utility model can be used in hair care appliances, such as hair dryers, straighteners, styling combs, etc. The accessory can be detachably connected to the hair care appliance or fixedly attached to it.

[0041] Although the present invention has been described in detail with reference to preferred embodiments, it should be understood that such detailed description is for illustrative purposes only and does not constitute a limitation thereof. The scope of the present invention is determined by the technical solutions defined in the claims.
