[0033] Example 1: As Figure 1-10 As shown, the hair dryer's duct structure includes an air inlet duct 2 and an air outlet duct 1. The air inlet duct 2 and the air outlet duct 1 are hollow. The air inlet duct 2 is telescopically connected to the air outlet duct 1, and the air inlet duct 2 and the air outlet duct 1 are connected. When the air inlet duct 2 retracts towards the air outlet duct 1, the duct structure can be adapted to a smaller housing. When the air inlet duct 2 extends away from the air outlet duct 1, the duct structure can be adapted to a larger housing. Gas enters from the air inlet duct 2 and is then blown out from the air outlet duct 1. This application enables the air inlet and outlet ducts to easily adapt to various housing designs, from compact to large. Because it can accommodate housings of multiple sizes, this design reduces the cost of making separate molds for products of different sizes, making it more economical and efficient for manufacturers. It greatly reduces the number of molds to be developed, thereby reducing production costs. When the air inlet duct retracts towards the air outlet duct, the duct structure can be adapted to smaller housings. When the air inlet duct extends away from the air outlet duct, the duct structure can be adapted to larger housings.

[0034] It also includes a connector 3, through which the air inlet duct 2 is telescopically connected to the air outlet duct 1. The connector allows the air inlet duct and the air outlet duct to be telescopically connected, thereby allowing the duct structure to be lengthened or shortened to adapt to different sized shells.

[0035] The connector 3 has a through hole 30, and the air inlet duct 2 and / or the air outlet duct 1 are at least partially placed in the through hole 30. The air inlet duct 2 and / or the air outlet duct 1 are telescopically connected to the connector 3 through the through hole 30, so that the air inlet duct and the air outlet duct can telescopically extend and retract within the connector, thereby allowing the air duct structure to become longer or shorter to adapt to housings of different sizes.

[0036] The inner wall of the connector 3 is provided with a spiral line, and the air inlet duct 2 and / or the air outlet duct 1 are provided with an assembly part corresponding to the spiral line. The air inlet duct 2 and / or the air outlet duct 1 are telescopically connected to the connector 3 through the cooperation of the spiral line and the assembly part 11, so that the air inlet duct and the air outlet duct can telescopic within the connector, thereby making the air duct structure longer or shorter to adapt to shells of different sizes.

[0037] The connector 3 is also equipped with a spring 32. One end of the spring 32 abuts against the air inlet duct 2, and the other end of the spring 32 abuts against the air outlet duct 1. The spring can absorb and store energy, and play a role in buffering and shock absorption. This helps to reduce the impact and wear between the air inlet duct and the air outlet duct, and extend the service life.

[0038] The air inlet duct 2 and / or the air outlet duct 1 are provided with a stop part 12 on their outer walls. The stop part 12 is placed inside the through hole 30. The stop part makes it difficult for the air inlet duct and / or the air outlet duct to fall out of the through hole.

[0039] The air inlet duct 2 is provided with an insert part 13 corresponding to the air outlet duct 1. The air inlet duct 2 is connected to the air outlet duct 1 through the insert part 13. When the air inlet duct 2 retracts towards the air outlet duct 1 and the air inlet duct 2 abuts against the air outlet duct 1, the insert part 13 is placed inside the air outlet duct 1.

[0040] The connector 3 includes a first housing 301 and a second housing 302. The first housing 301 is detachably assembled to the second housing 302. When a fault occurs inside the connector, the user or manufacturer can repair it by disassembling the connector.

[0041] The outer wall of the stop part 12 is provided with a rubber ring 121 for stopping, so that when the air outlet and / or air inlet are extended or retracted, the rubber ring can fix the air outlet and / or air inlet.

[0042] The first housing 301 is provided with a snap fastener 303, and the second housing 302 is provided with a snap fastener 304 corresponding to the snap fastener 303. The first housing 301 can be detachably assembled to the second housing 302 through the cooperation of the snap fastener 303 and the snap fastener 304. When a fault occurs inside the connector, the user or manufacturer can repair it by disassembling the connector.

[0043] The first housing 301 has an insertion block 305 on the side facing the second housing 302, and the second housing 302 has an insertion slot 306 corresponding to the insertion block 305. The first housing 301 can be detachably assembled to the second housing 302 through the cooperation of the insertion block 305 and the insertion slot 306. When the internal of the connector malfunctions, the user or manufacturer can repair it by disassembling the connector.

[0044] Example 2: Figure 11-12 As shown, a hair dryer includes a housing 4, a motor, and a blower casing structure. The housing 4 has an internal assembly space and is also provided with an air inlet for gas entry and an air outlet for gas exit. The blower casing structure is assembled inside the housing 4. The air inlet is opposite to the air inlet casing 2, and the air outlet is opposite to the air outlet casing 1. The motor, which is a high-speed brushless motor, is also assembled inside the air inlet casing 2. A heating element is also assembled inside the air outlet casing 1. This application allows the air inlet and air outlet casings to easily adapt to various housing designs, from compact to large. Because it can adapt to housings of various sizes, this... The design reduces the cost of creating individual molds for products of different sizes, making it more economical and efficient for manufacturers. It significantly reduces the number of molds needed, thereby lowering production costs. When the air inlet retracts towards the air outlet, the air duct structure can be adapted to smaller housings. When the air inlet extends away from the air outlet, the air duct structure can be adapted to larger housings. The use of a high-speed brushless motor improves the power performance and airflow output of the hair dryer, reduces noise, and makes the motor work more stably, enhancing the user experience. Furthermore, the high-speed brushless motor has a longer lifespan than traditional motors, thus extending the lifespan of the hair dryer.

[0045] The connector 3 has an outwardly protruding assembly part 33 on its outer wall. The assembly part 33 has a screw hole 330 for screws to pass through. The housing 4 has an assembly hole that matches the screw hole 330. The screw passes through the screw hole 330 and is assembled in the assembly hole, so that the connector 3 is fixedly assembled in the housing 4, and the blower's air duct structure can be fixed in the housing.
