[0028] Furthermore, unless otherwise defined, the technical and scientific terms used in this invention have the same meanings as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for the purpose of describing particular embodiments only and not for limiting the invention. It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof.

[0029] Example 1: As Figures 1-6As shown, the novel hair dryer casing structure includes an air inlet casing 1 and an air outlet casing 2. The air inlet casing 1 and the air outlet casing 2 are hollow. The air outlet casing 2 is provided with a snap fastener 21. The air inlet casing 1 is provided with a snap fastener block 11 corresponding to the snap fastener 21. The air outlet casing 2 is detachably assembled to the air inlet casing 1 through the cooperation of the snap fastener 21 and the snap fastener block 11. The air inlet casing 1 and the air outlet casing 2 are connected. This application uses snap fasteners and snap fasteners to detachably assemble the air inlet casing and the air outlet casing together. This design ensures that the air can be tightly sealed throughout the process of the air entering from the air inlet casing and flowing out from the air outlet casing, making it difficult for the air to escape. This results in a larger air volume, which significantly improves the blowing efficiency and greatly enhances the user experience. In the event of a malfunction, the air inlet casing and the air outlet casing can be disassembled for inspection and maintenance.

[0030] The latching block 11 is provided with an inclined surface that slopes from the top of the latching block 11 to the bottom of the latching block 11. The inclined surface makes it easier to assemble the latching buckle into the latching block.

[0031] The device includes a circuit board 3. The air inlet duct 1 is provided with a through hole 10 corresponding to the circuit board 3. The circuit board 3 is at least partially inserted into the air inlet duct 1 through the through hole 10. Both ends of the circuit board 3 are exposed outside the air inlet duct 1. Gas enters the air inlet duct from the air inlet. When the gas passes through the circuit board, it can cool the circuit board, prevent the circuit board from overheating and being damaged, and extend the service life of the blower.

[0032] Wherein, the width of the through hole 10 is greater than or equal to the thickness of the circuit board 3, and the portion of the circuit board 3 exposed outside the air inlet duct 1 is provided with large components. The large components are placed on the circuit board exposed outside the air inlet duct so as not to obstruct the flow of gas inside the air inlet duct. When the width of the through hole 10 is equal to the thickness of the circuit board 3, the gas is not easy to escape from the air duct, and the gas is cooled by passing through the circuit board inside the heat dissipation air inlet duct. When the width of the through hole 10 is greater than the thickness of the circuit board 3, the gas can flow out from the through hole to dissipate heat from the circuit board exposed outside the air outlet duct.

[0033] The air inlet duct 1 is provided with a fixing part 12 that protrudes outward from the outer wall of the air inlet duct 1, and the fixing part is provided so that the air inlet duct can be stably installed in the housing.

[0034] The air inlet duct 1 is arranged in a cross shape, which can further enhance the stability of the installation inside the housing.

[0035] The fixing part 12 has one or more sets, and the multiple sets of fixing parts 12 are arranged opposite to each other. The multiple sets of fixing parts enable the air inlet duct to be installed more stably in the housing.

[0036] The air inlet duct 1 and / or the air outlet duct 2 include a first housing 13 and a second housing 14. The first housing 13 is detachably assembled to the second housing 14. When a fault occurs inside the air inlet duct and / or the air outlet duct, the air inlet duct and the air outlet duct can be disassembled for inspection and maintenance.

[0037] The first housing 13 is provided with an insertion block 131, and the second housing 14 is provided with an insertion hole 141 corresponding to the insertion block 131. The first housing 13 can be detachably assembled to the second housing 14 through the cooperation of the insertion block 131 and the insertion hole 141. When a fault occurs inside the air inlet and / or air outlet, the air inlet and / or air outlet can be disassembled and repaired.

[0038] The insert block 131 has one or more sets, and the multiple sets of insert blocks 131 are arranged at intervals. The arrangement of multiple sets of insert blocks makes the first housing and the second housing more stably assembled together and less likely to be separated.

[0039] The device includes a brushless motor 15, which is installed inside the air inlet duct 1 and electrically connected to the circuit board 3. This enables the hair dryer to be lightweight, have high air pressure, and a long lifespan. Furthermore, the use of a brushless motor can reduce noise.

[0040] The fixing part 12 is also provided with mounting holes 120 for screw assembly, which facilitates the installation of screws to install the air inlet duct into the housing.

[0041] It also includes a heating element 22, which is assembled inside the air outlet duct 2. The heating element 22 is provided so that the gas can be heated and hot air can be blown out.

[0042] Example 2: As Figures 1-8 As shown, the hair dryer includes a housing 4 and the novel hair dryer nozzle structure. The housing 4 has an internal assembly space and is also provided with an air inlet 401 for gas entry and an air outlet 402 for gas exit. The hair dryer nozzle structure is assembled inside the housing 4. This application uses a snap-fit ​​block and snap-fit ​​buckle to assemble the air inlet and air outlet nozzle together. This design ensures that the gas can be tightly sealed throughout the entire process from entering the air inlet nozzle to exiting the air outlet nozzle, making it difficult for the gas to escape. This results in a larger air volume, which significantly improves the blowing efficiency and greatly enhances the user experience. In the event of a malfunction, the air inlet and air outlet nozzles can be disassembled for easy inspection and repair.

[0043] The top of the circuit board 3 abuts against the inner top wall of the housing 4, the bottom of the circuit board 3 abuts against the inner bottom wall of the housing 4, and the fixing part 12 abuts against the inner side wall of the housing, thereby enhancing the stability of the air inlet duct installed in the housing.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
