[0043] Example 1:
[0044] See also Figure 1-4As shown, the utility model relates to a multifunctional hair drying and care air nozzle, comprising an air duct 1, a wind cavity 11 is opened in the middle of the air duct 1 along the central axis L, a mounting cylinder 2 connected to the hair dryer is provided at one end of the air cavity 11, an air inlet 21 connected to the air cavity 11 is opened axially on the mounting cylinder 2, a first air outlet 5 is tangentially penetrated by the wall surface of the air duct 1, a first comb tooth 31 is provided on the wall surface of the air duct 1 upstream of the first air outlet 5, a flow guide structure is connected between the air cavity 11 and the first air outlet 5, and the flow guide structure comprises an upper wall 3 and a lower wall 4, which are part of the wall surface of the air duct 1, and the upper wall 3 and the lower wall 4 are connected to the wall surface of the air duct 1. The wall 4 cooperates to form an air outlet duct, which extends to the first air outlet 5. The lower edge wall 4 extends outward to form a first guide surface 41. The first guide surface 41 is located downstream of the first air outlet 5. The guide structure guides at least part of the airflow blown out of the first air outlet 5 to flow along the surface of the first guide surface 41. When blowing hair, the hair can be brought close to the first guide surface 41 and the hair dryer can be moved along the direction of airflow outflow. Under the action of the airflow, the hair can be blown dry and combed along the first guide surface 41, thereby making the dried hair smooth as a whole, avoiding the situation of hair flying up, heating and softening the hair for shaping, and also achieving the purpose of hair care and nourishment.
[0045] The radial direction refers to the direction from the center of a circle outward (or inward), that is, along the radius of the air duct. The radial direction refers to the direction from the central axis of the air duct toward the wall. The tangential direction is perpendicular to the radial direction and refers to the direction along the tangent of the circle. In this application, the tangential direction refers to the direction along the tangent of any point on the wall of the air duct.
[0046] The side of the upper wall 3 facing the air cavity 11 is a windward surface 33, and the side of the lower wall 4 facing away from the air cavity 11 is an air supply surface 47. The windward surface 33 and the air supply surface 47 are arranged opposite each other and cooperate to form an air outlet that overlaps vertically. The airflow in the air cavity 11 can flow along the surface of the air supply surface 47 under the guidance of the windward surface 33. The air supply surface 47 reliably guides the airflow along the first guide surface 41. A plurality of first comb teeth 31 are provided on the side of the upper wall 3 facing away from the air cavity 11.
[0047] The first air outlet 5 is provided with a plurality of first guide vanes 51 that divide the first air outlet 5 into a plurality of first air outlet grids 52. After the air flows out of the first air outlet 5, it can flow better along the surface of the first guide surface 41 due to the Coanda effect.
[0048] During operation, the first comb teeth 31 can be inserted into the hair, and the first comb teeth 31 straightens the hair and has the function of clamping and fixing the hair. At this time, the hair is supported on the first guide surface 41. The hair dryer provides an airflow of hot air or cold air from the air inlet 21 into the wind cavity 11, so that the air pressure in the wind cavity 11 increases, and the airflow flows out from the multiple first air outlet grids 52 of the first air outlet 5. The airflow is blown directly onto the hair. The user can comb the hair while blowing the air, and the position of combing the hair is consistent with the blowing position, so the blowing effect is better and the hair is more evenly affected by the wind.
[0049] Furthermore, the first comb teeth 31 are fin-shaped.
[0050] Furthermore, the air guide duct 1 is provided with windshields 43 on either side along the central axis L. When air flows out of the first air outlet 5, the windshields 43 on either side prevent the airflow from diffusing, helping to control the airflow within a certain range and concentrating the wind force within a certain area, thereby improving the drying effect. Specifically, a hair-confining space is formed between the two windshields 43 to better concentrate the hair on the first air guide surface 41, ensuring that the air blown out of the first air outlet 5 accurately acts on the hair between the windshields 43, thereby further optimizing the hair drying effect.
[0051] Furthermore, the outer wall of the mounting tube 2 is provided with a plurality of slide grooves 22, and the inner wall of the mounting tube 2 is provided with a plurality of sliders 23. The slide grooves 22 and sliders 23 are convenient for connection and installation with the hair dryer. The installation method can also adopt other elastic arms, concave and convex snap fit, magnetic attraction, spiral patterns and other methods.
[0052] Furthermore, the first air outlet 5 is arranged on the wall of the air guide duct 1 toward the left or right side of the air guide duct 1, so as to realize one-way single air outlet blowing of the air nozzle, that is, blowing to the left or blowing to the right, thereby facilitating the selection of users with different hand preferences.
[0053] For further information, see Figure 14-17 Shows how to use different functions of the product, such as Figure 14 The product moves from the upper left to the lower right, the first comb teeth 31 are inserted into the hair to comb the hair root end, and the hair tip end is adsorbed on the first guide surface 41 and floats freely; Figure 15 The product moves from the lower right to the upper left, the first comb teeth 31 are inserted into the hair to comb the hair root end, and the hair tip end is adsorbed on the first guide surface 41 and floats freely to the upper left; Figure 16 The product rotates from the lower right to the upper left, the first comb teeth 31 are inserted into the hair to comb the hair roots, and the hair tips are adsorbed on the first guide surface 41 and float freely in the wind. During the slow rotation, the hair sticks to the outer arc surface of the nozzle (the wall of the air guide tube) to achieve a curling effect. Figure 17 The product moves from right to left, the first comb teeth 31 are inserted into the hair to comb and limit the root end, and the hair tip end is adsorbed on the first guide surface 41 and floats freely, and as the product moves, the hair is combed, softened and straightened.
[0054] Example 2:
[0055] See also Figure 5-6 As shown, the second embodiment is based on the first embodiment, and the wall surface of the air duct 1 is tangentially penetrated with a first air outlet 5 and a second air outlet 6, and the second air outlet 6 and the first air outlet 5 are axially symmetrically arranged on the wall surface of the air duct 1, and the wall surface of the air duct 1 has first and second comb teeth 31 and 32 symmetrically on the left and right, and the first comb teeth 31 and the second comb teeth 32 are respectively located upstream of the first air outlet 5 and the second air outlet 6, and a first guide surface 41 and a second guide surface 42 are respectively provided downstream of the first air outlet 5 and the second air outlet 6, and the second guide surface 42 is intersected and connected with the first guide surface 41, and an angle α is formed between the second guide surface 42 and the first guide surface 41.
[0056] Among them, a guide structure is connected between the air cavity 11 and the second air outlet 6, and the guide structure guides at least part of the airflow blown out of the first air outlet 5 and the second air outlet 6 to flow along the surfaces of the first guide surface 41 and the second guide surface 42. Since the first guide surface 41 and the second guide surface 42 intersect and are connected, the airflow of the second guide surface 42 directly acts on the hair tips.
[0057] The second air outlet 6 is provided with a plurality of second guide vanes 61 which divide the second air outlet 6 into a plurality of second air outlet grids 62 .
[0058] In the second embodiment, the first air outlet 5 and the second air outlet 6 are tangentially provided on the wall of the air guide duct. Compared with the first embodiment, the addition of the second air outlet 6 can achieve the effect of pressure relief and noise reduction, providing the user with a better user experience. The first air outlet 5 and the second air outlet 6 are symmetrically arranged to achieve a one-way double-outlet air outlet effect of the air nozzle. The first air outlet 5 and the first comb teeth 31 are used with the right hand to achieve left-direction double-outlet air outlet, and the second air outlet 6 and the second comb teeth 32 are used with the left hand to achieve right-direction double-outlet air outlet. Whether it is left-direction double-outlet air outlet or right-direction double-outlet air outlet, it can be used in conjunction with the comb teeth to quickly tidy up frizzy hair, so that the wind direction is consistent with the direction of the hair. While combing the hair with the comb teeth, blowing air is performed simultaneously to quickly smooth frizzy hair, make the hair slide smoothly downward, and prevent hair from flying. For users who use both hands, the left and right hands can alternately blow and comb their hair without turning the switch.
[0059] Further, such as Figure 18The product moves from right to left, the first comb teeth 31 are inserted into the hair to comb the hair root end, and the hair tip end is adsorbed on the first guide surface 41 and floats freely. As the product moves, the hair is combed, softened and straightened. Compared with the embodiment Figure 17 As shown in the scheme, the hair is subjected to wind forces from two different directions, namely the first air outlet 5 and the second air outlet 6, and the hair ends are quickly flipped up and down, which accelerates the separation of moisture from the hair and the drying.
[0060] Example 3:
[0061] See also Figure 7-8 As shown, the third embodiment is based on the second embodiment, the first guide surface 41 and the second guide surface 42 are not directly connected at the end, but only the extension lines of the two intersect. When the air flows out from the first air outlet 5 and the second air outlet 6 at the same time, the airflow leaves the first guide surface 41 and the second guide surface 42 for a distance and then meets and converges into one airflow, which can also achieve the function of the above-mentioned second embodiment; different from the second embodiment, such as Figure 19 The airflow shown in a converges into one stream and continues to flow forward, as shown in Figure 19 As shown in c to d, the larger the angle between the extension lines of the first guide surface 41 and the second guide surface 42, the larger the distance between the two airflows. When the first guide surface 41 and the second guide surface 42 are parallel, the two airflows move forward roughly in parallel. At this time, the comb teeth are not used and are only used for blowing function, such as Figure 19 a, b, c, d form different modes of nozzles for selection.
[0062] Example 4:
[0063] See also Figure 9 As shown, this fourth embodiment builds on the foundation of the first embodiment, with third comb teeth 44 disposed at the end of the first straight guide surface 41. The third comb teeth 44 extend along the first straight guide surface 41, or are disposed perpendicularly to the edge of the first straight guide surface 41. The third comb teeth 44 are fin-shaped. The first and third comb teeth 31, 44 divide the hair on the first straight guide surface 41 into several bundles, improving the uniformity of the airflow applied to the hair. In this embodiment, the third comb teeth 44, disposed perpendicularly to the edge of the first straight guide surface 41, achieve a superior drying effect. The first and third comb teeth 31, 44 are located upstream and downstream of the first air outlet 5, respectively. The ends of the hair on the first straight guide surface 41 are evenly isolated and clamped by the first and third comb teeth 31, 44, respectively. The airflow from the first air outlet 5 acts on the hair, resulting in more uniform heating.
[0064] Embodiment 5:
[0065] See also Figure 10-11As shown, the fifth embodiment is based on the first embodiment, and a fourth comb tooth 45 is provided on the first guide surface 41. The fourth comb tooth 45 is vertically provided on the first guide surface 41. The fourth comb tooth 45 divides the hair located on the first guide surface 41 into several bundles, thereby further improving the uniformity of the hair receiving wind.
[0066] Example 6:
[0067] See also Figure 12-13 As shown, the sixth embodiment is based on the first embodiment, and a first air outlet 5 and a second air outlet 6 are symmetrically provided on the air guide duct 1, and a fourth comb tooth 45 and a fifth comb tooth 46 are provided on the first guide surface 41 and the second guide surface 42 respectively.
[0068] See also Figure 1-19 As shown, the first comb teeth 31, the second comb teeth 32, the third comb teeth 44, the fourth comb teeth 45 and the fifth comb teeth 46 mentioned in Examples 1 to 6 are round-headed comb teeth. Through the design of the round-headed comb teeth, the first comb teeth 31, the second comb teeth 32, the third comb teeth 44, the fourth comb teeth 45 and the fifth comb teeth 46 can easily pass through the hair, and can effectively comb hair that is easily knotted or tangled, reducing the difficulty in combing.
[0069] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
