[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: a drying device with a telescopic and retractable ventilation duct, mainly composed of a main body 1 and a ventilation duct 2. Among them, the ventilation duct 2 is located inside the air outlet of the main body 1, and the ventilation duct 2 itself can be telescoped. When extended, the hot air flow generated by the main body 1 will be conveyed through the ventilation duct 2 to achieve the purpose of being dried. After being completely retracted, the entire ventilation duct 2 is hidden inside the main body 1, which is convenient for storage, does not occupy space, and at the same time hides the pipe in the whole machine, making the whole product more integral and more beautiful.

[0022] In addition, the ventilation duct 2 includes an initial duct 21 connected to the air outlet of the main unit 1 (which is the starting point of the entire ventilation system). A number of telescopic ducts 22 are movably connected inside the initial duct 21 (these parts together form a telescopic ventilation system. In addition, the number of telescopic ducts 22 can be adjusted as needed to adapt to different length requirements). Among the number of telescopic ducts 22, the size of each section decreases step by step (the size of the telescopic duct 22 decreases step by step, which means that the duct closer to the air outlet is smaller in size. This design may be to reduce the resistance when air flows and maintain the overall stability and structural strength). The top end of the telescopic duct 22 with the smallest size is connected to an air outlet hood 23. Guide rail grooves 211 are provided on the inner walls of the initial duct 21 and each section of the telescopic duct 22. Guide rail strips 221 are connected to the outer surfaces at the bottoms of each section of the telescopic duct 22. The guide rail strips 221 slide inside the guide rail grooves 211 (this is to guide the sliding and positioning of the telescopic duct 22. The design of the guide rail and the guide rail groove not only ensures the smoothness of the telescopic movement but also ensures the stability and centering of the telescopic duct during the telescopic process). Clamping steps one 212 are provided at the top ends of the initial duct 21 and each section of the telescopic duct 22. Clamping steps two 222 are connected to the bottom ends of each section of the telescopic duct 22. After the telescopic duct 22 is fully extended, the clamping step one 212 abuts against the clamping step two 222 (this can prevent each section of the telescopic duct 22 from overextending). Clamping grooves 213 are opened on the inner sides at the tops of the initial duct 21 and each section of the telescopic duct 22. Clamping protrusions 223 are connected to both sides at the bottoms of each section of the telescopic duct 22. After the telescopic duct 22 is fully extended, the clamping protrusions 223 are engaged inside the clamping grooves 213. The clamping protrusions 223 and the clamping grooves 213 are hemispherical structures that are adapted to each other (when each section of the telescopic duct 22 is fully extended, the mutual engagement of the hemispherical clamping protrusions 223 and the clamping grooves 213 can prevent each section of the telescopic duct 22 from automatically retracting).

[0023] Finally, the host 1 includes a housing 11 (the housing 11 protects the internal components and provides a basis for structural support). Air inlet windows 12 are provided on both sides of the housing 11 (the air inlet windows 12 allow external air to enter the interior of the host 1, providing necessary conditions for subsequent heating). An air outlet 13 is reserved at the top of the housing 11, and a handle 14 is fixedly connected thereto (the handle 14 facilitates the handling or movement of the host 1). A front cover 18 is snap-connected to the front of the housing 11, and a touch screen 19 is embedded on the surface of the front cover 18 (the touch screen 19 is the main interface for the user to interact with the host. The user can set parameters such as temperature and wind speed through the touch screen, and view the working status of the host. This is well-known prior art content and will not be elaborated here). A duct 15, a fan 16, and a heating element 17 (the heating element 17 is an electric heating element) are respectively installed inside the housing 11. The air duct inside the duct 15 is in a "U" - shaped structure. The air inlet of the duct 15 is connected to the air inlet window 12. The heating element 17 is installed inside the air outlet of the duct 15. The air inlet of the fan 16 is connected to the air outlet of the duct 15, and the air outlet of the fan 16 is connected to the air outlet 13.

[0024] During use, when the ventilation duct 2 is extended and the air outlet hood 23 is lifted by hand, each telescopic duct 22 will extend in sequence. After the extension is in place, the clamping protrusion 223 and the clamping groove 213 will engage with each other to prevent retraction. Subsequently, the host 1 is connected to the mains power supply. The air outlet hood 23 is aligned with or inserted into the object to be dried. The host 1 is started, and the fan 16 and the heating element 17 are operated. The fan 16 allows external air to enter the interior of the duct 15 through the air inlet window 12. After the air is heated by the heating element 17, the hot air is delivered to the extended ventilation duct 2 through the fan 16 and the air outlet 13, and is then delivered to the object to be dried through the ventilation duct 2. After drying, the ventilation duct 2 is retracted into the host 1, and that's it.
