Description

Technical Field

[0001] The utility model belongs to the technical field of hair care tools, and specifically relates to a bidirectional curly hair air suction nozzle and a hair curling iron. Background Art

[0002] A hair curling iron is one of the commonly used hair styling tools. It mainly forms curly hair by winding hair around a heating rod body and using high temperature to deform the hair. However, this kind of hair curling iron that uses a high-temperature heating component to change the shape of the hair is likely to cause irreversible damage to the hair, and the heating component of the hair curling iron is exposed, which is easy to scald the skin of the user. Therefore, by changing the traditional heating rod method and using the method of blowing hot air to heat the hair, the same styling effect can be achieved, and at the same time, the damage to the hair can be reduced. For example, in the publicly disclosed technical literature "CN111887565A, A Hair Curling Iron Assembly and a Hair Dryer Using the Hair Curling Iron Assembly", the effect is that when the hair is placed near the hair curling iron assembly, the hair can adhere to the outer surface of the deflector under the action of the air pressure difference and produce a curly hair effect under the action of the discharged air flow. The function of curling hair can be realized through the hair curling iron assembly with the above structure, which can avoid irreversible damage to the hair;

[0003] In the actual use process, it is usually necessary to switch left and right to curl the hair on both sides. The shape of the curly hair is greatly related to the blowing direction. Based on the above structure, the air outlet direction of the hair curling iron is unique. Assuming that the hair curling iron is held in the right hand, when curling the hair on both sides, the blown air is in the same direction, so the curling direction must be the same. However, this will cause the hair styles on the left and right sides to be asymmetric and not beautiful. If the air outlet direction needs to be changed, when switching the curling position, it is necessary to change from holding the hair curling iron with the right hand to the left hand. However, most people have weaker left hand strength and cannot hold the hair curling iron for a long time to curl the hair. Summary of the Utility Model

Detailed implementation manners

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0035] Please refer to Figure 1-7 ;

[0036] The air suction nozzle of the present invention can realize the switching of two different blowing directions, clockwise and counterclockwise, of a nozzle to meet the needs of different usage situations of users. Specifically, it includes an air nozzle body 11. An air duct 12 is formed inside the air nozzle body 11. The air duct 12 forms a first opening 13 and a second opening 14 at both ends of the air nozzle body 11 respectively. In this embodiment, the shape of the air nozzle body 11 is not limited. It can be a common cylinder on the market at present, or other special-shaped columnar structures. A plurality of air outlets 114 communicating with the air duct 12 are arranged on the outer surface of the air nozzle body 11. The airflow blown out from the air outlets 114 has a direction. Assuming that the shape of the air nozzle body 11 is a cylinder, then the direction of the airflow blown out is tangent to the surface of the air nozzle body 11. The airflow blown out from a plurality of air outlets 114 arranged at intervals around the surface of the air nozzle body 11 forms an annular or spiral airflow ring with attached-wall flow, creating a negative pressure on the surface of the air nozzle body 11. When hair approaches, it will be adsorbed and wound around the surface of the air nozzle body 11;

[0037] The air nozzle in the utility model is an accessory, which cannot generate airflow by itself. Therefore, when using it, it needs to be used in conjunction with a hair dryer or an airflow generating device compatible with it, and the air outlet end of the tool is connected to the first opening 13 of the air nozzle body 11 in the initial state. At this time, the second opening 14 is closed by the air valve structure. When the airflow of the tool enters the airway 12 from the first opening 13, the air pressure in the airway 12 increases, causing the gas in the airway 12 to overflow from the plurality of air outlets 114 to form a jet airflow. At this time, the jet airflow is in a clockwise direction. When the airflow needs to be blown out in the opposite direction according to the usage, it is only necessary to remove the air nozzle body 11 from the tool, and change the direction so that the second opening 14 is connected to the air outlet end of the tool, and use the air valve structure to close the first opening 13. Then, start the tool again to allow the airflow to enter the airway 12 from the second opening 14. The air pressure in the airway 12 increases, causing the gas in the airway 12 to overflow from the plurality of air outlets 114 to form a jet airflow. At this time, the jet airflow is in a counterclockwise direction.

[0038] Assuming that the tool is initially held in the right hand and the airflow is clockwise, when the airflow direction needs to be switched, it is only necessary to change the direction of the nozzle body 11 and connect it to the tool again. The operation is simple and the tool can still be held in the right hand. Compared with the products of the prior art, it is more convenient for people to use. Moreover, the present solution can switch between two blowing directions on one nozzle, so people do not need to purchase multiple nozzles with different air outlet directions as backup, which can save usage costs.

[0039] Of course, the above is only one example of the use process. In real life, people can choose whether to connect the tool to the first opening 13 or the second opening 14, and the air valve structure will then close the other opening. In addition, detachable fixing structures for the tool are provided at both ends of the nozzle body 11.

[0040] The air valve structure in the utility model has multiple implementations, as long as the purpose is to close another opening when one opening is connected to the air outlet end. In one embodiment, the air valve structure can be an independent accessory, such as a sealing cover; when the air outlet end of the tool is connected to the first opening 13, the sealing cover is used to block the second opening 14, and when the use direction needs to be switched, it is only necessary to remove the sealing cover from the second opening 14, and after the installation position is changed, the second opening 14 is connected to the air outlet end of the tool, and then the sealing cover is used to block the first opening 13; using the sealing cover is the simplest and most direct way, but as an independent component, it is very easy to lose, and the sealing cover contains a silicone component, which ages faster in a hot environment for a long time; therefore, another implementation method is proposed;

[0041] Specifically, it includes several guide rails 151 provided inside the air nozzle body 11, and a movable valve 152 that reciprocally slides between the first opening 13 and the second opening 14. The guide rails 151 extend from the first opening 13 towards the second opening 14 and are in the same extending direction as the air passage 12. A number of clamping positions 153 are provided on the outer periphery of the movable valve 152 and are in sliding fit with the guide rails 151. Fixed parts 154 are respectively provided at the first opening 13 and the second opening 14, and the fixed parts 154 are in contact with the outer edge of one surface of the movable valve 152.

[0042] In the initial state, the air outlet end of the tool is connected to the first opening 13 of the air nozzle body 11. When high-speed air flow enters and exits the first opening 13 of the tool, the high-speed air flow moves from the first opening 13 towards the second opening 14. At this time, no matter which position the movable valve 152 is in, it will be pushed towards the second opening 14 by the high-speed air flow, and the outer edge of one end face of the movable valve 152 abuts against the fixed part 154 at the second opening 14. Assuming that the air passage 12 formed inside the air nozzle body 11 is a cylinder, then the movable valve 152 is in the shape of a circular sheet. The movable valve 152 can be made of a metal material and is relatively light as a whole. There is a gap between its outer periphery and the inner wall of the air nozzle body 11 to avoid friction, and the fixed part 154 is in the shape of a circular ring. Preferably, there is also a small gap between the clamping positions 153 and the guide rails 151 to facilitate the sliding of the movable valve 152, and the fixed part 154 covers all the guide rails 151. That is, while one end face of the movable valve 152 abuts against the fixed part 154, the small gap between the clamping positions 153 and the guide rails 151 is covered, so that the gas will not flow out from the small gap. During normal use, high-speed air flow will continuously be generated and continuously exert a thrust on the other end face of the movable valve 152, so that the end face of the movable valve 152 remains in contact with the fixed part 154, that is, remains in a state of blocking the second opening 14, avoiding air leakage.

[0043] When the position needs to be switched, reverse the direction so that the second opening 14 is connected to the air outlet end of the tool. At this time, the movable valve 152 is located at the second opening 14. Then start the tool again so that the high-speed air flow enters the air passage 12 from the second opening 14. At the same time, the movable valve 152 is pushed to move from the second opening 14 towards the first opening 13, so that the other end face of the movable valve 152 abuts against the fixed part 154 at the first opening 13, thereby blocking the first opening 13.

[0044] Adopting the above air valve structure can effectively prevent the problem of accessory loss. At the same time, there is no need for the user to manually operate. Only need to reverse the positions of both ends of the air nozzle body 11 and then start the tool to generate air flow, and the operation is simple and fast.

[0045] One embodiment of the present utility model relates to the air nozzle body 11, specifically including an inner bracket 111, on which several air outlet parts 112 are formed. An outer cylinder 113 is fixedly arranged on the outer periphery of the inner bracket 111. The outer cylinder 113 is made of a metal material with a thickness of 0.5 - 1.2 mm. Several air outlets 114 communicating with the air outlet parts 112 are arranged on the surface of the outer cylinder 113. The several air outlets 114 are inclined to spray out the air flow in the same direction. When in use, the hair is wound around the outer cylinder 113. In addition to the high-speed air flow sprayed out from the air outlets 114 to adsorb the hair, the inner bracket 111 can also transfer heat to the outer cylinder 113 to heat and shape the hair.

[0046] Preferably, several air outlets 114 are arranged along the extending direction of the outer cylinder 113, in a narrow strip shape, and are distributed in an annular array centered on the outer cylinder 113.

[0047] Further, the outer cylinder 113 includes a first connecting part 1131 and a second connecting part 1132. A connecting plate 1133 is arranged at intervals between the first connecting part 1131 and the second connecting part 1132. In this embodiment, the outer cylinder 113 is in a cylindrical shape, so the first connecting part 1131 and the second connecting part 1132 are circular rings, and the several connecting plates 1133 arranged at intervals are arc-shaped. A first air guiding part 1134 is arranged on one side of the connecting plate 1133, and the first air guiding part 1134 extends obliquely inwards, forming an air outlet 114 with one side of the adjacent connecting plate 1133.

[0048] Correspondingly, the inner bracket 111 includes a third connecting part 1111 and a fourth connecting part 1112. Several connecting ribs 1113 are arranged at intervals between the third connecting part 1111 and the fourth connecting part 1112. A second air guiding part 1114 is arranged between two adjacent connecting ribs 1113. The shape of the second air guiding part 1114 is adapted to the shape of the connecting plate 1133, and the outer side of the second air guiding part 1114 is closely attached to the inner side of the connecting plate 1133, which is more convenient for transferring heat to the connecting plate 1133. In addition, one end of the second air guiding part 1114 protrudes from the connecting rib 1113 to form an air outlet part 112, and the air outlet part 112 corresponds to the air outlet 114, forming an air outlet gap a of 0.25 - 0.45 mm, so that the air flow forms the Coanda effect after coming out of the outer cylinder 113.

[0049] Preferably, the second air guiding part 1114 is several connecting strips 1115 arranged in parallel at intervals. The several connecting strips 1115 are arranged at intervals longitudinally, that is, the outer edge of the connecting strip 1115 abuts against the inner side of the connecting plate 1133. The air flow in the air passage 12 can directly contact the connecting plate 1133, so as to transfer heat. In this embodiment, the several connecting strips 1115 and the inner side of the connecting plate 1133 together play a role in guiding the air flow, guiding the air flow to be evenly blown out from a plurality of air outlet parts 112.

[0050] Since the air guide part two 1114 is arc-shaped, and one end protrudes from the connecting rib 1113, and a boss 1116 is provided outside the connecting rib 1113, the boss 1116 abuts against the end of the air guide part one 1134. Through such a structure, the relative rotation between the outer cylinder 113 and the inner bracket 111 can be limited, thereby achieving fixation.

[0051] Preferably, the guide rail 151 and the connecting rib 1113 are integrally formed.

[0052] The present utility model also discloses a hair curler, referring to Figure 6 and Figure 7 , which includes a rod body 2 and the above-mentioned bidirectional curly hair air suction nozzle. The rod body 2 can generate a high-speed air flow flowing into the air nozzle body 11. In addition, both ends of the bidirectional curly hair air suction nozzle are detachably connected to the rod body 2. The specific disassembly structure can be a buckle or a magnetic attraction, which is convenient for the fixation and disassembly of the air nozzle body 11. The specific application method and principle can refer to the above-mentioned embodiments, and the same technical effects can be achieved, which will not be elaborated here one by one.

[0053] The following will explain the detachable structure;

[0054] Specifically, magnetic attraction components one 31 are provided at both ends of the air nozzle body 11, and magnetic attraction components two are provided on the rod body 2. A magnetic fixation structure 3 is formed by the magnetic attraction components one 31 and the magnetic attraction components two. Using the magnetic structure as the fixation method can more conveniently switch the air nozzle body 11;

[0055] Preferably, the magnetic attraction component one 31 includes a decorative part 311, and a magnetic conduction ring 312 is provided in the decorative part 311. The magnetic conduction ring 312 can be a magnet or a magnetic conduction metal material. A magnetic ring 32 that cooperates with the magnetic conduction ring 312 is provided inside one end of the rod body 2. The magnetic ring 32 has magnetism and can play a magnetic attraction role on the magnetic conduction ring 312. The decorative part 311 abuts against the end of the rod body 2. Through the setting of the decorative part 311, the above-mentioned parts can be covered to be more beautiful;

[0056] In addition, the inner bracket 111 should be slightly longer than the outer cylinder 113, and a small part of the inner bracket 111 extends out from the end face of the decorative part 311 so that it can be inserted into the rod body 2, making the gas entry smoother.

[0057] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
