[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] See also Figure 1-9 The present invention provides an embodiment: a portable hair dryer, comprising a housing 2, wherein a fan 4, an air suction duct 9 and an air blowing duct 5 are provided in the housing 2; the air suction duct 9 and the air blowing duct 5 are independently provided. It should be noted that the air suction duct 9 and the air blowing duct 5 are independently provided, and the air suction duct 9 and the air blowing duct 5 may be provided without being connected, or the air suction duct 9 and the air blowing duct 5 may be connected through a fan in the middle to realize air circulation. It should be emphasized that the airflow between the air suction duct 9 and the air blowing duct 5 will not share the same air duct space at the same time, and the air sucked in by the air suction duct 9 and the airflow blown out by the air blowing duct 5 will not interfere with each other.

[0036] Because the air suction duct 9 and the air blowing duct 5 are independently arranged, it is possible to blow air to the hair and absorb water from the hair simultaneously when drying the hair.

[0037] If the suction duct 9 and the blowing duct 5 share the same duct and are not independently configured, the suction and blowing will interfere with each other, making it difficult to achieve simultaneous suction and blowing. This is much less efficient than if the suction duct 9 and the blowing duct 5 are independently configured so that suction and blowing can occur simultaneously. The fan 4 is used to generate suction, and the suction duct 9 is connected to the fan 4 so that the suction duct 9 forms a negative pressure to absorb moisture from the hair to be dried, while the blowing duct 5 blows air to dry the hair to be dried.

[0038] Comb teeth 3 are provided on the end surface of the housing 2. It should be noted that the end surface of the housing 2 can be provided on any surface of the housing 2. The comb teeth 3 are in contact with the hair to be dried. The function of the comb teeth 3 can be to guide the absorption of moisture from the hair to be dried, or to guide the blown air flow to dry the hair to be dried.

[0039] In order to achieve the above functions, a suction part and a blowing part can be provided on the hair dryer, and either the suction part or the blowing part can be provided on the comb teeth 3, or both the suction part and the blowing part can be provided on the comb teeth 3. Furthermore, the suction part and the blowing part can be provided on different comb teeth 3 respectively, or both the suction part and the blowing part can be provided on the same comb teeth 3.

[0040] In one embodiment, Figure 5 and Figure 6 As shown, a suction portion is provided on the end surface of the housing 2 (understandably, on the surface of the hair dryer provided with the comb teeth 3 or in the gaps between the comb teeth). The suction portion can be in the form of a hole, a mesh, or a long slot. The suction portion is connected to the suction duct 9 and functions to absorb moisture from the hair to be dried to facilitate hair drying. A blowing portion is then provided on the comb teeth 3, and can be provided on the surface / end surface of the comb teeth 3 or at a certain endpoint or end of the comb teeth 3. The blowing portion is connected to the blowing duct 5 and functions to blow air to dry the hair to be dried.

[0041] In one embodiment, Figure 5 and Figure 6 As shown, the positions of the suction part and the blowing part can be interchanged. For example, the blowing part can be arranged on the end surface of the housing 2, while the suction part can be arranged on the surface of the comb teeth 3 or on the end surface, a certain end point, or an end of the comb teeth 3. The suction part is connected to the suction duct 9 and its function is to absorb moisture from the hair to be dried to facilitate hair drying. The blowing part is connected to the blowing duct 5 and its function is to blow air to dry the hair to be dried.

[0042] In another embodiment, Figure 7As shown, the air suction part and the air blowing part can be simultaneously arranged on the end surface of the comb teeth 3. In practice, the air suction part and the air blowing part can be arranged on the same comb tooth, or the air suction part and the air blowing part can be arranged on different comb teeth respectively.

[0043] When the suction part and the blowing part are arranged on the same comb tooth, the suction part and the blowing part can be arranged on the same side of the comb tooth, or they can be arranged on different sides of the comb tooth. No matter which method is chosen, it is necessary to design a suction duct 9 to cooperate with the suction part, and a blowing duct 5 to cooperate with the blowing part.

[0044] When the suction part and the blowing part are provided on different comb teeth, the comb teeth can be designed. The comb teeth 3 include suction comb teeth 301 and blowing comb teeth 302. The suction part is provided on the suction comb teeth 301, and the suction part of the suction comb teeth 301 is connected to the suction air duct 9 to guide the moisture in the hair to be dried from the suction comb teeth 301 into the suction air duct 9 and be sucked away; the blowing part is provided on the blowing comb teeth 302, and the blowing part of the blowing comb teeth 302 is connected to the blowing air duct 5 to guide the air flow to be blown out from the blowing comb teeth 302.

[0045] During use, through the provided comb teeth structure, the alternating arrangement of the suction comb teeth 301 and the blowing comb teeth 302, and the connected blowing duct 5 and the suction duct 9, through the operation of the fan 4, the suction duct 9 is suctioned at a negative pressure, and the blowing duct 5 is blowing at a positive pressure. The hot air circulates between the comb teeth and inside the hair dryer, reducing the amount of hot air blown into the air around the head, making it convenient for the hot air to act directly and concentratedly on the hair, and greatly improving the hair drying speed.

[0046] Because of the special structure of the comb teeth, the comb teeth can penetrate deep into the roots of the hair and then perform a blowing and suction action on the hair. The moisture at the roots of the hair is directly sucked, and then the inner part of the hair is dried simultaneously. The suction duct 9 forms a negative pressure and the blowing duct 5 blows out airflow simultaneously. This is different from other hair dryers in the prior art. Because they do not have a comb tooth structure, they cannot penetrate deep into the roots of the hair or even the inner part to perform a blowing and suction operation, nor do they have a solution for combining blowing and suction simultaneously. They can only blow hair close to or near the hair. Compared with the comb teeth of this solution that penetrate deep into the hair to perform a suction and blowing combined drying efficiency, the efficiency is significantly lower. In addition, the hair dryers in the prior art are at a certain distance from the hair when drying, and they cannot dry closely to the hair. A large part of the blown air is dissipated into the air before entering the hair and cannot be well utilized. This is also a major reason for the low hair drying efficiency of the prior art hair dryers. The comb teeth of this solution solve the above problems very well, so compared with the prior art, this solution can greatly improve the hair drying efficiency.

[0047] It should be noted that, in some embodiments, the fan 4 serves as the main body for generating negative pressure suction, that is, it serves as the main power source for the suction force to absorb moisture from the hair to be dried, and also serves as the power source for the airflow blown out of the blowing duct 5; but in other embodiments, the fan 4 can only serve as the source of negative pressure suction, and not as the power source for the airflow blown out of the blowing duct 5. In this case, other power fans / motors such as blower motors can be additionally provided to provide the blowing duct 5 with the power source for the airflow required for its work, to generate airflow to dry the hair to be dried, and even other external air sources can be directly connected to directly provide the blowing duct 5 with the airflow required for its work, or other similar and equivalent alternative solutions such as the blowing channel being directly or indirectly connected to the atmosphere should all be within the protection scope of this solution.

[0048] Furthermore, the fan 4 serves as the main power source of the suction force for sucking away moisture from the hair to be dried, and also as the power source of the air flow blown out of the blowing duct 5. The fan 4 has a fan suction port 404 and a fan outlet 405. The fan suction port 404 is connected to the suction duct 9, and the fan outlet 405 is connected to the blowing duct 5, so that the hair dryer can perform suction and blowing operations simultaneously; suction and blowing can work simultaneously. Although in some embodiments, suction and blowing can work in a time-sharing manner or the start timing can be achieved through human intervention; however, the best hair drying effect is to perform suction and blowing on the hair at the same time, because blowing while sucking can absorb moisture from the hair to be dried, and at the same time blow the hair to be dried, and the moisture of the hair that is not easily dried can be absorbed by the blower, especially the root part of the hair by combining blowing and suction. After the suction function is integrated into the hair dryer, the residual moisture at the root of the hair can be easily sucked away; especially for women with long hair, through the configuration of combined blowing and suction, the hair can be dried by simply combing the comb from the root to the end several times, which greatly improves the efficiency of hair drying and is a qualitative leap compared to the existing technology.

[0049] Furthermore, in order to dry the hair faster, hot air can be used to blow the hair. A heating plate 10 can be provided for this purpose. The heating plate 10 is configured to heat the air inside the portable hair dryer to form hot air, which is then blown out through the blowing duct 5 and blown towards the hair to be dried. In this way, the hot air can be sucked into the suction duct 9 together with the moisture in the hair to be dried, so that the hot air can be circulated between the blowing duct 5, the hair to be dried, and the suction duct 9 to promote the efficiency of drying the hair, while reducing the working time of the heating plate 10 and achieving energy-saving effects. The heating plate 10 is located on the outside of the fan 4. The heating plate 10 includes an inner ring plate 1001, an outer ring plate 1002 and a heating wire 1003. The outer ring plate 1002 is arranged on the outside of the inner ring plate 1001, and the heating wire 1003 is fixedly installed between the outer ring plate 1002 and the inner ring plate 1001. The setting of the heating plate 10 facilitates the heating wire 1003 to heat the air, thereby improving the heating efficiency. At the same time, the combined use of the inner ring plate 1001 and the outer ring plate 1002 also enhances the stability and durability of the heating plate.

[0050] Furthermore, the fan 4 includes an electric motor 401, a cover 402 and blades 403. The electric motor 401 is fixedly installed on one side of the cover 402, and the blades 403 are arranged on the other side of the cover 402. The output end of the electric motor 401 is fixedly connected to the blades 403, which reduces energy loss during power transmission and improves the working efficiency of the fan.

[0051] Furthermore, the blowing comb teeth 302 can be arranged to be located between two adjacent suction comb teeth 301, so as to conveniently absorb moisture from the hair while drying the hair, thereby increasing the hair drying speed.

[0052] Furthermore, it also includes an air guide mechanism, the blowing air duct 5 and the blowing comb teeth 302 are connected through the air guide mechanism, and the air guide mechanism includes an air guide cylinder 6, a gas distributor 7 and a connecting pipe 8; the air guide cylinder 6 is fixedly connected to one side of the gas distributor 7, and the connecting pipe 8 is fixedly connected to the other side of the gas distributor 7. There are multiple connecting pipes 8, and the number of connecting pipes 8 and the blowing comb teeth 302 are the same and the positions correspond to each other. The setting of the air guide mechanism allows the airflow to be evenly and accurately distributed to each blowing comb tooth 302 when blown out, ensuring that the airflow can directly act on the hair, thereby improving the hair drying efficiency.

[0053] Furthermore, when the portable hair dryer is working, the blowing comb teeth 302 and the suction comb teeth 301 dry the hair to be dried at the same time; the suction comb teeth 301 are used to guide and suck away moisture from the hair to be dried, while the blowing comb teeth 302 are used to guide the airflow to blow towards the hair to be dried, so that the hair dryer can suck and blow air at the same time when it is running, and the drying time, drying efficiency and technical effects are better than the drying effect of sucking and blowing air at the same time.

[0054] Furthermore, suction slots 3011 are provided on the end faces of the suction comb teeth 301, and the suction slots 3011 serve as the suction part; the end faces can be any surface on the suction comb teeth, and in some embodiments the end faces can be divided into upper, lower, left, right, front and rear end faces; in one embodiment, suction slots 3011 are provided on the end faces of the suction comb teeth 301, and blowing slots 3021 are provided on the end faces of the blowing comb teeth 302, and the blowing slots 3021 serve as the blowing part; the end faces can be any surface on the blowing comb teeth, and in some embodiments the end faces can be divided into upper, lower, left, right, front and rear end faces. In one embodiment, the end face of the blowing comb teeth 302 is provided with a blowing slot 3021; ​​the suction slot 3011 is used in conjunction with the blowing slot 3021, so that the suction comb teeth 301 can form a more concentrated airflow when sucking air, thereby improving the suction efficiency, and at the same time, the blowing comb teeth 302 can form a more uniform and concentrated airflow when blowing air, thereby improving the blowing efficiency. At the same time, the setting of the three blowing slots 3021 also enables the airflow to cover the hair more comprehensively, further improving the hair drying effect.

[0055] Furthermore, a handle 1 is fixedly installed below the shell 2, a lithium battery is provided inside the handle 1, and a charging port for the lithium battery is provided below the handle 1. The arrangement of the handle 1 and the lithium battery makes the hair dryer portable and has long battery life, thereby increasing its practicality.

[0056] At the same time, it should be noted that the shape of the comb teeth 3 should not be limited by the embodiments of the accompanying drawings. In a specific implementation design, the comb teeth 3 can be configured to be flat, cylindrical, conical, annular, spherical, elliptical, or semicircular, etc. Figure 8 and Figure 9 In conventional embodiments, the comb teeth 3 can be made into a flat shape. Of course, in other embodiments, they can also be made into a cylindrical, conical, ring-shaped, spherical, etc. In other embodiments, the comb teeth 3 can also be made into a ring or semi-ring shape, such as a circular ring with a hollow center.

[0057] In this embodiment, the comb teeth 3 serve as a structural component in the hair dryer that guides dry hair. Conventional limitations should not be placed on these components, and the comb teeth 3 mentioned in this embodiment should not be directly associated with the shape of conventional comb teeth. The concept of the comb teeth 3 in this embodiment should not be narrowed down. The concept of the comb teeth 3 should be further extended to encompass its functionality. For example, a structure similar to the design of this embodiment, protruding from the end face of the hair dryer and providing a function for guiding dry hair, could be considered equivalent to the comb teeth in this embodiment.

[0058] To facilitate the implementation of the solution, in one embodiment, the hair dryer can be made into an integrated design or a split design. If an integrated design is adopted, the housing 2 can be integrally formed, and if a split design is adopted, the hair dryer can be made into a detachable design. Specifically, the head and body of the hair dryer can be designed to be detachable, so that the comb teeth 3 can be designed on the head of the hair dryer. The head of the hair dryer can then be installed on the body of the hair dryer according to the needs of the user during use, or can be removed from the body of the hair dryer for easy storage after use.

[0059] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
