Description

Technical Field

[0001] The utility model relates to the technical field of hair dryers, in particular to an air nozzle structure and a hair dryer. Background Art

[0002] A hair dryer is a common electrical device that draws outside air into it, heats it, and blows it out at high speed, thereby accelerating the evaporation of moisture and achieving the effect of drying hair. It is often used in hairdressing and daily hair care.

[0003] With the development of society and the continuous improvement of people's living standards, the functions of hair dryers have become diversified. People pay more attention to the care and styling of hair when using hair dryers. For example, the wind blown out by early hair dryers on the market is orthogonal to the hair in its natural state, which causes the hair to fly up when the wind is blown out, and even causes hair damage. In order to solve the problem of hair flying up, relevant manufacturers have successively developed air nozzles. By changing the guide structure at the air outlet, the air nozzle can flow close to the plane where the air outlet is located, and then can guide the airflow to flow along the hair, so as to achieve overall smoothness of the hair, prevent hair from flying up, and avoid hair damage.

[0004] However, after the nozzle in the traditional technology is installed on the blowing port of the hair dryer, the problem of inconvenience in use still exists; specifically, when the user holds the hair dryer, he still needs to lift the hair dryer from a distance to point the nozzle towards the hair. After long-term use, the hands are easily fatigued, which is not in line with human physiomechanics and the user experience is not good, so it needs to be improved.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

When a component is considered to be "disposed on" another component, it may be directly disposed on the other component or there may be a centrally located component.

They are only for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure. They should not be understood as a limitation of the present invention.

[0039] The following is combined with Figure 1-3 The technical solution of the utility model is further illustrated through specific implementation methods.

[0040] Example 1:

[0041] Please refer to Figure 1 An embodiment of the present invention provides a nozzle structure, including a nozzle body 1. In this embodiment, the nozzle body 1 is arranged in a block structure. For the convenience of description, one of the side surfaces of the nozzle body 1 is used as a reference. At this time, the nozzle body 1 has six directions: left side, right side, front side, rear side, top side and bottom side.

[0042] Based on this, the nozzle body 1 has a first side surface 2 and a second side surface 3 adjacent to each other, wherein the first side surface 2 is located on the front side of the nozzle body 1, and the second side surface 3 is located on the left side of the nozzle body 1. On this basis, an air inlet 21 is provided through the first side surface 2, and correspondingly, an air outlet 31 is provided through the second side surface 3.

[0043] The nozzle body 1 has an air flow channel 5 therein, which is used to connect the air inlet 21 with the air outlet 31 to facilitate air flow. In this embodiment, the interior of the nozzle body 1 is hollow to form the air flow channel 5. It should be explained that in other embodiments, pipes, guide plates and other structures can also be added to the interior of the nozzle body 1 to form the air flow channel 5. Regardless of the channel structure used, it should be included in the interpretation scope of the air flow channel 5.

[0044] Based on the above arrangement, since the air outlet of the hair dryer is usually located at its front end, when the nozzle body 1 is installed, the first side surface 2 of the nozzle body 1 is opposite to the hair dryer, and the nozzle body 1 is installed on the hair dryer; here, the nozzle body 1 is connected to the hair dryer through the air inlet 21, so that the air outlet of the hair dryer is connected to the air inlet 21 of the nozzle body 1, and the wind force generated by the hair dryer can enter the interior of the nozzle body 1 through the air inlet 21, and then the air flow is finally blown out from the air outlet 31 under the action of the air flow channel 5, thereby achieving a smooth conduction effect.

[0045] Furthermore, the nozzle body 1 is provided with a first guide portion 6 at a position close to the air outlet 31. The first guide portion 6 is used to guide the air flow blown out from the air outlet 31 toward the second side surface 3, which is equivalent to Figure 1 The middle airflow is blown out toward the lower side of the nozzle body 1, so that it can be consistent with the direction of the hair. The airflow can be blown along the length direction of the hair, avoiding as much as possible the curling or scattering of the hair caused by blowing in the orthogonal direction.

[0046] At the same time, when the user holds the hair dryer, since the first side surface 2 and the second side surface 3 are adjacent to each other, the directions of the air outlet 31 and the air inlet 21 are perpendicular to each other, thereby guiding the airflow to be discharged from one side of the hair dryer; under this condition, the user only needs to place his upper arm in front of the chest and then raise his forearm to place the air outlet 31 opposite to the hair, thereby avoiding excessively raising the upper arm, saving effort when operating the hair dryer, better meeting the needs of human ergonomics, and reducing fatigue during use.

[0047] Reference Figure 1 and Figure 2In order to further optimize the user experience of the nozzle structure, the nozzle body 1 also has a third side surface 4, which is adjacent to the first side surface 2, and the third side surface 4 is arranged opposite to the second side surface 3, which is equivalent to the third side surface 4 being located on the right side of the nozzle body 1; optionally, the third side surface 4 is an arc-shaped concave surface, and the arc-shaped concave surface starts from the front side of the nozzle body 1 and extends to the rear side of the nozzle body 1.

[0048] Based on the above structural setting, the purpose of setting the third side 4 as an arc-shaped concave surface is to avoid the head. For example, when the user needs to blow the hair on the right side of the head, he only needs to hold the hair dryer with his right hand and bring the nozzle structure close to the right side of the head, so that the second side 3 is opposite to the hair; then when the user needs to blow the hair on the left side of the head, he only needs to move the hair dryer directly from the right side to the left side. At this time, the third side 4 is opposite to the head, and the arc-shaped concave surface can accommodate the head, and can also make the second side 3 close to the hair.

[0049] On the one hand, the above-mentioned arc-shaped concave surface can prevent the blower from hitting the head when changing sides, and realize direct side-changing use; on the other hand, it can also shorten the distance between the air outlet 31 and the head after changing sides, so that the wind can reach the hair, and the user experience is optimized and improved. The user can achieve an anti-flying blowing effect on the hair in various areas of the head without changing hands.

[0050] Furthermore, when the arc-shaped concave surface is set, the arc-shaped concave surface can also gradually narrow the airflow channel 5; wherein, for ease of understanding, the arc-shaped concave surface has a first side end close to the front side of the nozzle body 1 and a second side end close to the rear side of the nozzle body 1. In the process of the arc-shaped concave surface extending from the first side end to the second side end, the depression amplitude gradually increases to achieve the effect of narrowing the airflow channel 5; through the above-mentioned structural setting, on the one hand, the width of the area close to the rear side of the nozzle body 1 can be made thinner, and when in use, it can provide the head with greater freedom of movement, which is convenient for operation; on the other hand, by narrowing the airflow channel 5, the airflow can be gradually pressed into the air outlet 31 of the second side 3 after flowing into the air inlet 21, thereby achieving a good air duct effect.

[0051] Reference Figure 3 In order to enable the airflow to be blown along the direction of the hair, specifically, the first guide portion 6 includes guide surfaces respectively close to both sides of the air outlet 31, and the two guide surfaces are inclined toward the same side. In this embodiment, the guide surfaces are inclined toward the lower side of the nozzle body 1, so that an acute angle is formed between the air outlet direction of the air outlet 31 and the second side surface 3. At this time, the two guide surfaces can guide the airflow to flow as close to the second side surface 3 as possible and blow it toward the lower side, so that the airflow can be cared for from top to bottom along the direction of the hair.

[0052] It needs to be explained that, although the airflow blown out from the air outlet 31 in this solution will flow along the surface of the second side surface 3, it does not mean that all the airflow blown out from the air outlet 31 will be parallel to the second side surface 3. The "airflow blown out from the air outlet 31 will flow along the surface of the second side surface 3" here can be understood as: the angle between the airflow blown out from the air outlet 31 and the surface of the second side surface 3 is an acute angle.

[0053] Optionally, when the guide surface is specifically set, in one embodiment, it can be a planar structure, and in another embodiment, it can be a curved surface structure with an arc; in this embodiment, one of the guide surfaces adopts a planar structure, and the other guide surface adopts a curved surface structure, and the guide surface with a curved surface is located below the guide surface with a planar structure; here, based on the combination scheme shown in this embodiment, the curved surface structure can better guide the airflow to adhere to the second side surface 3 when the air is discharged, and the airflow flow is more stable, further improving the effect of drying and straightening the hair close to the air outlet surface, and the problem of preventing hair from flying when blowing is solved.

[0054] It is understandable that in actual applications, the two guide surfaces can also be set as a plane structure at the same time, or the two guide surfaces can be set as an arc structure at the same time. There is no restriction on the specific setting combination of the guide surfaces. No matter what kind of guide combination is used, it should be included in the scope of interpretation of this scheme.

[0055] Reference Figure 2 and Figure 3 In order to enable the airflow to enter the air outlet 31 more smoothly from the airflow channel 5, a second guide portion 7 is further provided on the nozzle body 1. The second guide portion 7 is located in the airflow channel 5 and is adjacent to the air outlet 31; specifically, the second guide portion 7 intersects with the first guide portion 6, and the second guide portion 7 guides the airflow in the airflow channel 5 to the air outlet 31.

[0056] Optionally, under the condition that the air flow channel 5 adopts a cavity structure, the second guide portion 7 may adopt a guide structure such as a pipe or a guide plate, and the air flow can be guided into the air outlet 31 through the above structure.

[0057] In this embodiment, the second guide portion 7 guides the flow through a guide surface. Specifically, a guide protrusion is provided on the inner wall of the second side surface 3, and the surface of the guide protrusion forms the guide surface, which is a plane and / or an arc surface.

[0058] It should be explained that the specific setting form of the guide surface can be used in combination with the setting form of the first guide part 6. In one of the matching methods, for example, when the guide surface is a planar structure, the guide surface can also be adjusted to a plane. By connecting the guide surface with the guide surface, the guide surface and the second guide part 7 are made flush, and the airflow is not easily blocked during flow, thereby achieving a smooth wind-guiding effect; in addition, when the guide surface is an arc-shaped structure, the guide surface can also be adjusted to an arc-shaped structure. By connecting the guide surface with the guide surface and making an arc-shaped transition between the guide surface and the second guide part 7, the arc-shaped transition method is conducive to guiding the airflow toward the lower side, and can also achieve a smooth wind-guiding effect.

[0059] The two docking methods shown above can also be used in combination, that is, multiple guide surfaces can be planes and arc surfaces respectively; for example, in the present embodiment, because the two guide surfaces adopt plane and arc surface structures respectively, when setting the second guide part 7, the number of guide surfaces is first adapted to the guide surface, and the two guide surfaces are set as planes and arc surfaces respectively, and then the two guide surfaces are matched to the two guide surfaces; at this time, under the combination of the two docking methods, on the one hand, most of the air volume can be guided to the air outlet 31 under the condition of flush docking, and under the action of the circular transition, more airflow is guided to be close to the second side surface 3 when the air is discharged, so that the airflow can efficiently flow from the air flow channel 5 to the air outlet 31.

[0060] Replay Figure 1 In order to further optimize the user experience of the air nozzle structure, in this embodiment, the air outlet 31 is a long hole, and the air outlet 31 extends from the side of the second side 3 close to the first side 2 to the side of the second side 3 away from the first side 2; based on the above configuration, a larger air outlet area can be obtained, thereby increasing the air output of the air outlet 31.

[0061] Furthermore, the air outlet 31 can be set to multiple, such as two, three or six lights. The specific number of the air outlet 31 can be adjusted according to actual needs. The specific number of the air outlet 31 is not limited here. In this embodiment, the number of air outlets 31 is selected as three for example; accordingly, the number of the first air guide part 6 and the second air guide part 7 should be adapted to the number of air outlets 31, which will not be elaborated here; on this basis, multiple air outlets 31 are arranged at intervals on the second side 3, which can further increase the air outlet volume, and can also make the air outlet action more uniform, thereby optimizing the experience during use.

[0062] In addition, the second air guide portion 7 can be set in a variety of ways. In one embodiment, the second air guide portion 7 can be directly set on the inner wall of the nozzle body 1 as an integral part, which can reduce the manufacturing cost of the nozzle body 1; but when the number of air outlets 31 is set to multiple, because there will be more guide surfaces on the second air guide portion 7, the inner wall contour of the nozzle body 1 will become complicated, making it difficult to demold, which is not conducive to molding in the mold and easily affects the overall structural accuracy of the product. Therefore, the second air guide portion 7 can also be set by a split assembly method.

[0063] Specifically, refer to Figure 2 The nozzle body 1 includes an outer shell 11, an inner shell 12 and a cover 13, wherein the air inlet 21, the air outlet 31 and the first air guide part 6 are arranged on the outer shell 11. At this time, the air inlet 21, the air outlet 31 and the first air guide part 6 can be formed on the outer shell 11 through the core pulling mechanism on the mold, which facilitates the partial molding and demolding of the outer shell 11.

[0064] At the same time, a take-in and put-out port is opened on one side of the outer shell 11, wherein the take-in and put-out port can be set on the upper side, lower side and right side of the outer shell 11. In this embodiment, the take-in and put-out port is set on the right side of the outer shell 11, that is, the position of the third side surface 4. By setting the take-in and put-out port, the inner shell 12 can be installed in the outer shell 11 to meet the assembly requirements.

[0065] It should be noted that no matter whether the access port is set on the upper side, lower side or right side of the outer shell 11, it can meet the installation requirements of the inner shell 12. Therefore, in other embodiments, the position of the access port can be adjusted. In this embodiment, no specific restrictions are made. No matter where the access port is opened, any method that can install the inner shell 12 into the outer shell 11 should be included in the scope of interpretation of this solution.

[0066] Furthermore, the inner shell 12 is disposed within the outer shell 11, and the second air guide 7 is disposed on the inner shell 12. During the specific configuration, the outer contour of the inner shell 12 can first be adapted to the inner cavity of the outer shell 11. Under this condition, the inner shell 12 can be positioned in contact with the outer shell 11 during placement, preventing the inner shell 12 from shaking during the air blowing process and providing a more secure installation. Furthermore, by disposing the second air guide 7 on the inner shell 12 and providing a core-pulling mechanism in the mold, the second air guide 7 can be molded separately, which facilitates molding and demolding, simplifying the molding process of the second air guide 7.

[0067] Furthermore, a cover 13 is provided on the outer shell 11 and is used to open and close the access opening. After the inner shell 12 is placed into the outer shell 11, the access opening is closed to prevent the inner shell 12 from coming loose, thereby ensuring the structural stability of the nozzle body 1. Typically, a first snap fastener is provided on the edge of the outer shell 11, and a second snap fastener is provided on the edge of the cover 13. By interlocking the first snap fastener with the second snap fastener, the inner shell 12 is prevented from coming loose.

[0068] Optionally, in order to further improve the connection stability between the outer shell 11 and the inner shell 12, the nozzle structure also includes a threaded fastener 8, wherein a threaded blind hole 111 is provided on the inner side of the outer shell 11, and a through hole 121 is provided on the inner shell 12. After the inner shell 12 is placed into the outer shell 11, the threaded blind hole 111 is connected with the through hole 121. At this time, the threaded fastener 8 adopts a screw structure, and the threaded fastener 8 passes through the through hole 121 and is threadedly connected to the threaded blind hole 111. In this way, the outer shell 11 and the inner shell 12 can be fixed to each other, and the connection stability between the outer shell 11 and the inner shell 12 is improved.

[0069] The implementation principle of this embodiment: by arranging the air inlet 21 on the first side 2 and the air outlet 31 on the second side 3 adjacent to the first side 2, the user only needs to simply raise his forearm in front of the body when holding the hair dryer. At this time, the air outlet 31 can be just opposite to the hair. Compared with the conventional air nozzle structure, there is no need to raise the upper arm excessively, which is more labor-saving and convenient to use and meets the requirements of human body mechanics; and in the process of reversing use, the arc-shaped concave surface can avoid the head, and the blowing experience is significantly improved.

[0070] Example 2:

[0071] This embodiment discloses a hair dryer, including a hair dryer body and the nozzle structure of the first embodiment. Based on the first embodiment, the features not explained in this embodiment adopt the explanation in the first embodiment and will not be repeated here.

[0072] The nozzle structure is connected to the hair dryer body so that the air inlet 21 is connected to the air outlet of the hair dryer body. Specifically, the nozzle structure and the hair dryer body are detachably connected. Under the condition of adopting a detachable connection, the nozzle structure can be removed, which is more flexible to use. Specifically, when setting it up, a snap structure or a threaded connection structure can be set on the nozzle body 1 and the hair dryer body. The specific connection relationship between the nozzle body 1 and the hair dryer body is not limited here.

[0073] It needs to be explained that the nozzle structure in this embodiment can be adapted to be installed in hair dryers of various structures or models, whether it is a hair dryer with a linear shell or a T-shaped shell, or a hair dryer with an arbitrarily bendable shell, etc. This embodiment does not impose specific restrictions on the shell structure of the hair dryer. No matter what hair dryer structure is adopted, it should be included in the scope of interpretation of this application.

[0074] So far, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
