[0029] Specifically, please refer toFigure 4 Further, the hollow mounting base 2 is slidably mounted on the guide assembly, and the bottom of the hollow air distribution pipe 1 is provided with a plurality of second air distribution holes 8 which are uniformly distributed; further, the central axis of the second air distribution hole 8 is vertically arranged; the guide assembly can adopt a slide rail or other equivalent components which can limit the vertical sliding of the hollow mounting base 2.

[0030] Specifically, please refer to Figure 4 The guide assembly comprises two fixed seats 9 and a guide rod 10 fixedly mounted between the two fixed seats 9, and the guide rod 10 passes through the through hole 6 on the mounting lug 5; further, the fixed seat 9 is detachably connected with the window frame on the window to be defogged through bolts or the like; the inner diameter of the through hole 6 is slightly smaller than the outer diameter of the guide rod 10; the guide assembly adopts the fixed seat 9 and the guide rod 10, and the connection between the guide assembly and the hollow mounting base 2 can be realized by directly using the through hole 6 on the mounting lug 5, and the guide assembly does not need to be provided with a too complex structure for connecting with the hollow mounting base 2, and the fixed connection or the up-down sliding installation of the hollow mounting base 2 can be selected according to the height of the glass, thereby improving the applicability of the device.

[0031] Specifically, the hollow air distribution pipe 1 and the hollow mounting base 2 are made of light alloy material; the light alloy material can effectively reduce the self-weight of the device while ensuring the structural strength of the device, facilitate the up-down movement of the hollow air distribution pipe 1, and effectively reduce the energy consumption of the fan 3.

[0032] The glass defogging device provided in the embodiment has the guide assembly fixedly mounted on the window to be defogged, and in the initial state, the hollow air distribution pipe 1 is located at the bottom of the glass to be defogged; after the fan 3 is started, the pressure in the hollow air distribution pipe 1 increases, the air flow thrust sprayed through the second air distribution hole 8 is greater than the self-weight of the glass defogging device, and the hollow air distribution pipe 1 gradually moves from bottom to top, thereby gradually and comprehensively defogging the surface of the glass to be defogged from top to bottom, and further improving the defogging effect and efficiency of the glass.

[0033] Embodiment 2

[0036] Specifically, the fan 3 is a speed-regulating fan 3; further, a frequency converter is installed in the hollow mounting seat 2, and the frequency converter is electrically connected with a motor on the speed-regulating fan 3, and the speed of the fan 3 is adjusted by frequency conversion of the motor, and the speed-regulating fan 3 can adopt a conventional product known in the market, and the specific structure and principle thereof will not be further limited and described herein.

[0037] The glass defogging device provided by the embodiment adopts the storage battery 11 for power supply, instead of wired power supply, so that the movement of the device up and down can be avoided to be interfered by the wires, and the movement freedom of the device is improved; the air flow blown out of the first air distribution hole 7 is arranged at an acute angle with the glass to be defogged, so that the hot air flow is reflected downward after being blown to the glass surface, thereby reducing the volatilized water vapor from floating upward close to the glass, and avoiding secondary adhesion of the water vapor, and the air flow ejected from the hollow air distribution pipe 1 also has a certain upward blowback effect on the hollow air distribution pipe 1, which is beneficial to the upward sliding of the hollow air distribution pipe 1 along the guide rod 10; when the hollow mounting seat 2 moves upward along the guide rod 10, the speed of the fan 3 is increased, and the hollow air distribution pipe 1 moves from bottom to top; when the hollow air distribution pipe 1 reaches the top of the window, the speed of the fan 3 is reduced until the reaction force of the air flow blown out of the first air distribution hole 7 and the second air distribution hole 8 is smaller than the weight of the device, and the hollow air distribution pipe 1 moves from top to bottom; the hollow air distribution pipe 1 always bears the reaction force of the air flow during the downward movement, so that the device is prevented from directly falling and being damaged under the action of gravity; meanwhile, the hot air flow always acts on the glass surface, and the glass surface is kept heated and defogged during the upward and downward movement of the device.

[0038] The use process of the glass defogging device is as follows: the hollow mounting seat 2 is installed on the upper part of the window to be defogged by screwing through the through hole 6, the fan 3 is started, the electric heating element 4 heats the air blown into the hollow air distribution pipe 1 by the fan 3, the heated air is blown to the surface of the glass to be defogged through the first air distribution hole 7, and the hot air flow is blown to the glass surface from top to bottom, so that the evaporation of the water mist on the glass surface is accelerated due to the temperature rise, and the defogging treatment of the glass surface is realized.
