Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1 to FIG. 5 , the present invention provides a vehicle-mounted defogging doll 100. The vehicle-mounted defogging doll 100 can be used as a vehicle ornament to be suspended on the top of the car. Preferably, the vehicle-mounted defogging doll 100 is suspended On the bracket of the car's interior rearview mirror, no additional suspension points are required.

The vehicle-mounted defogging doll 100 includes a head shell 1, a bottom shell 2, a stretching assembly 3 and a defogging device 4. The head shell 1 and the bottom shell 2 are movably connected through the stretching assembly 3, so The defogging device 4 is mounted on the bottom casing 2 .

The head housing 1 is suspended on the bracket of the interior rearview mirror of the automobile by means of a lanyard. Specifically, the head housing 1 includes a main body 11 enclosing a receiving space and a hanging ring 12 movably connected to the main body 11 . The main body 11 is formed with a protrusion 111 and an engaging portion 112 fixed to the end of the protrusion 111 extending toward the direction close to the hanging ring 12 . The tangential directions at the protrusions 111 are parallel.

The hanging ring 12 has a through hole 121 corresponding to the position of the protrusion 111 , the protrusion 111 extends through the through hole 121 and extends into the receiving space, and the engaging portion 112 is completely accommodated in the receiving space. Further, the protrusion 111 and the engaging portion 112 are both cylindrical, and the diameter of the engaging portion 112 is larger than the diameter of the through hole 112, and the body 11 can be suspended correspondingly On the hanging ring 12, the body 11 can rotate around the protrusion 111 as a whole, so that the defogging vehicle-mounted defogging doll 100 can have different faces facing the occupants in the vehicle to obtain an all-round shape display.

Further, the head housing 1 further includes a column 13 extending from the center of the main body 11 into the receiving space, and a wire outlet hole 14 provided through the main body 11 . The wire outlet hole 14 is disposed at the bottom end of the main body 11 , that is, the connection line between the wire outlet hole 12 and the protrusion 111 passes through the center of the main body 11 .

The stretching assembly 3 includes a coil spring 31, a wire groove 32 and a pull rope 33. One end of the coil spring 31 is fixed on the upright column 13, and the other end is fixed on the wire groove 32. The wire groove 32 is wound around the The upright post 13 rotates, and the pull rope 33 is wound around the wire slot 32 . It can be understood that the head casing 1 is further provided with an annular groove at the position corresponding to the wire groove 32, and the wire groove 32 is accommodated in the annular groove and rotates in the annular groove, which can effectively Avoid deviation of the wire groove 32 .

One end of the pulling rope 33 is fixed on the wire groove 32 , and the other end extends out from the wire outlet hole 14 . The bottom shell 2 is fixed to the movable end of the pulling rope 33 .

When the bottom shell 2 is pulled, the wire slot 32 rotates, which drives the coil spring 31 to rotate and shrink, and the elastic potential energy increases. At this time, the pull rope 33 is correspondingly elongated, and the length of the pull rope 33 can be adjusted according to actual needs. set, which is not limited in the present invention.

Loosen the bottom shell 2 , the coil spring 31 is driven back by elastic potential energy, drives the wire groove 32 to rotate, and rewinds the pull rope 33 back to the wire groove 32 .

The bottom shell 2 encloses an accommodating space, and the defogging device 4 is accommodated in the accommodating space. The defogging device 4 includes a fan 41 and an air guide channel 42, and the fan 41 is arranged in the air guide. One end of the channel 42 is used to introduce the outside air into the air guide channel 42.

Outside air passes through the ventilation holes 21 , the fan 41 moves to generate high-speed airflow, and the high-speed airflow passes through the air guide channel 42 and is discharged from the air outlet 22 .

The longitudinal cross-sectional area of the air guide channel 42 is gradually reduced from the fan 41 to the air outlet 22, so that the opening area of the air outlet 22 is small, which can ensure that the wind speed blown from the air outlet 22 is relatively large. Hair dryer is better.

A plurality of the ventilation holes 21 are discharged at equal intervals along the bottom shell 2 to form a mesh shape, and air enters through the ventilation holes 21. At the same time, the use of a plurality of the tiny ventilation holes can also be used to isolate dust. function to prevent a large amount of dust from entering the air guide channel.

The fan 41 can be charged by an energy storage battery, and can also be directly connected to electricity from an OBD interface or a cigarette lighter interface of a car through a conductive wire, which is not limited in the present invention.

The fan 41 includes a switch and a gear controller, and the switch and the gear controller are both disposed on the outer surface of the bottom housing 2 for easy operation.

Further, the air guide channel 42 is also provided with a plurality of heating resistance wires 43, and the heating resistance wires 43 are arranged on the side of the air guide channel 42 close to the air outlet 22. Further, in this embodiment, , the number of the heating resistance wires 43 is three. After the heating resistance wire 43 is energized, the air can be heated, so that the air outlet 22 outputs hot air. combination to obtain different heating power. The heating resistance wire 43 and the fan 41 have the same power supply mode, and the heating resistance wire 43 and the fan 41 are arranged in parallel, and the operating states of the two can be independent of each other.

Further, a rag can be fixed on the outer surface of the bottom shell 2, and the rag is used to preliminarily remove the water mist on the windshield. Preferably, the rag and the bottom shell 2 are connected by magic. The rag connection can be conveniently and quickly replaced.

When the vehicle-mounted defogging doll 100 is in use, directly hold the bottom shell 2 for extraction, the drawstring of the stretching assembly 3 is correspondingly extended, move the bottom shell 2 to the area that needs to be defogged, and then Turn on the fan 41 to blow air to a specific area of the windshield to reduce the temperature of the inner surface of the windshield, thereby reducing the temperature difference between the inner and outer surfaces of the windshield and avoiding the formation of fog; The heating resistance wire 43 is activated at the same time as the fan 41, so that the heating resistance wire 43 heats the cold air, so that the air outlet 22 blows out the hot air, continuously blows the windshield, and can dry the water on the windshield. Fog can also achieve the purpose of defogging. The two usage modes of the defogging device 4 can be selected according to actual needs, and the usage is fast and convenient.

Compared with the related art, the vehicle-mounted defogging doll provided by the present invention includes a head shell and a bottom shell, and the head shell and the bottom shell are connected by a stretching assembly, so that the bottom shell is It can be moved at will.
