AI Technical Summary
Existing car hair dryers are difficult to quickly and effectively remove frost, rain and snow from the outside glass of the car, and the heating speed is slow, and the scraper may cause glass scratches. The defroster is costly and has low efficiency. The wiper is easy to freeze in winter. , affect driving safety.
A hair dryer with a narrow air outlet including a shell, a wind energy generator and a heating device is designed. Through the narrow air outlet and arc-shaped over-surface design, the air flow is rapidly heated and changed direction, so as to quickly increase the heat when moving at a constant speed. It is used outside the car, supports USB or cigarette lighter interface or built-in battery power.
It realizes the rapid and safe removal of frost, rain and snow on the car glass, improves driving safety, and the heating speed in the car is faster than that of traditional heating systems without leaving any trace.

Abstract
Description
Technical Field
[0001] The invention relates to the field of hair dryers, and specifically to a hair dryer which can be used to remove ice and frost from the exterior of a car, remove rain and snow, and heat the air inside the car for heating. Background Art
[0002] Although there are many types of existing hair dryers, their structures are similar. However, there are more hair dryers for home use and fewer for car use. Existing hair dryers can only remove moisture on the internal window glass. For this reason, we propose a hair dryer that can be used outside the car to remove frost and increase the temperature inside the car. Frost on the car glass in northern winter, scraping with a scraper will cause glass scratches; the cost of defrost is too high and the speed is slow; the middle position of the front windshield cannot be touched. The car's own warm air is too slow; with the windshield wiper water, the wiper will sometimes be frozen. It can quickly remove frost, rain and snow on the car glass, greatly improving driving safety and removal speed without leaving any traces. When used outside the car, one end of the interface is designed with a USB or cigarette lighter to connect to the power supply, or it is designed as a wireless charging model with a built-in battery for more convenient hand-held use. The narrow and long air outlet design can cover the middle position of the car's front windshield. Summary of the invention
[0003] Technical issues solved
[0004] This type of hair dryer includes a shell, which horizontally forms an air duct. The air outlet is located directly below the air duct, and the air inlet is located on the side of the air duct. The wind energy generating device is located on the side of the air duct close to the air inlet, and the heating device is located on the side of the air duct close to the air outlet. The narrow and long air outlet design can quickly heat up a large area when moving at a uniform speed, thereby quickly defrosting the glass without damaging it, and the temperature in the car increases faster than the original warm air air conditioner.
[0005] Technical Solution
[0006] To achieve the above object, the following technical scheme is adopted: A hair dryer for use outside a vehicle with a narrow and long air outlet comprises a housing (1), a wind energy generating device (2), a heating device (3), an air inlet (4) and an air outlet (5); the wind energy generating device (2) is used to draw airflow from the air inlet (4) into the hair dryer and blow it out from the air outlet (5) to form an air duct (6); the heating device (3) is used to heat the airflow; the wind energy generating device (2) comprises a fan blade and a motor for driving the fan blade to rotate. An air duct (6) is arranged in the housing (1); one end of the air duct (6) is the air outlet (5), and the other end of the air duct (6) is the air inlet (4); the heating device (3) and the wind energy generating device (2) are arranged in sequence on one side from the air outlet (5) to the air inlet (4); a driving control device (7) is located at a handheld position to control the wind energy generating device (2) and the heating device (3). The air duct (6) is between the air inlet (4) and the air outlet (5), and an arc-shaped transition surface (8) is provided on the side wall away from the air inlet (4). The driving control device (7) is pressed to control the wind energy generating device (2) and the heating device (3). The air from the air inlet (4) encounters the arc-shaped transition surface (8) in the air duct (6) and changes direction. After encountering the heating device (3) and being heated, the air is discharged from the air outlet (5). The wind energy generating device is provided inside the shell, and the front end of the wind energy generating device is provided with an air inlet. When used outside the car, one end of the interface is designed to be connected to a power source such as a USB or a cigarette lighter, or is designed to be a wireless charging model with a built-in battery for greater convenience when held in hand. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 The driving control device (7) is pressed to control the wind energy generating device (2) and the heating device (3), and the air from the air inlet (4) encounters the arc transition surface (8) in the air duct (6) and changes direction, encounters the heating device (3) and is heated before being discharged from the air outlet (5). In the accompanying drawings: 1, housing 2, wind energy generating device 3, heating device 4, air inlet 5, air outlet 6, air duct 7, driving control device 8, arc transition surface. DETAILED DESCRIPTION
[0008] The driving control device (7) is pressed to control the wind energy generating device (2) and the heating device (3), and the air passes through the air inlet (4) and encounters the arc-shaped transition surface (8) in the air duct (6), whereupon the air changes direction, and then passes through the heating device (3) to be heated and discharged from the air outlet (5).
