Embodiment 1

[0055] Such as Figure 1-2As shown, the present embodiment provides a gun sight with fog and dust removal functions, including a lens barrel 1, a lens 2 and a fog and dust removal module, the lens 2 is installed at the end of the lens barrel 1; the lens barrel 1 is provided with a second A ventilation slot 11 and a second ventilation slot 12; the defogging and dust removal module includes an outer cover 3 and a fan, the outer cover 3 is set outside the lens barrel 1 and forms an accommodating space with the outer wall of the lens barrel 1, and the fan is rotatably arranged in the accommodating space , and the fan is located between the first ventilation slot 11 and the second ventilation slot 12 , and the second ventilation slot 12 is located on the side close to the lens 2 . The fan can rotate so that the gas in the lens barrel 1 enters the accommodation space from the first ventilation slot 11, and blows to the lens 2 through the second ventilation slot 12 to remove fog and / ...

Embodiment 2

[0075] This embodiment provides a driving assembly that can be applied to Embodiment 1 to drive the fan blade 4 to rotate.

[0076] Such as Figure 4 As shown, the fan blade 4 is rotatably sleeved on the lens barrel 1 through the bearing 7 to support the fan blade 4 . At this time, the drive assembly includes a first magnet circle 61 and a second magnet circle 62, the first magnet circle 61 is arranged on the inner wall of the housing 3, and the first magnet circle 61 is coaxially arranged with the lens barrel 1; the second magnet circle 62 It is arranged on the fan blade 4 , and the second magnet ring 62 is arranged coaxially with the lens barrel 1 . When the first magnet ring 61 is energized, the fan blade 4 can rotate relative to the lens barrel 1 . Specifically, when the first magnet circle 61 and the second magnet circle 62 are energized, the magnetic field generated by them changes, so that the second magnet circle 62 rotates, and then the fan blade 4 rotates.

Embodiment 3

[0079] This embodiment provides a driving assembly that can be applied to Embodiment 1 to drive the fan blade 4 to rotate.

[0080] Such as Figure 5 As shown, the fan blade 4 is suspended and sheathed on the lens barrel 1 . At this time, the drive assembly includes a third magnet circle 63 and a fourth magnet circle 64, the third magnet circle 63 is arranged on the outer wall of the lens barrel 1, and the third magnet circle 63 is coaxially arranged with the lens barrel 1; the fourth magnet circle 64 is arranged on the wall of the mounting hole of the fan blade 4, and the fourth magnet ring 64 is arranged coaxially with the lens barrel 1. When the third magnet ring 63 and the fourth magnet ring 64 are energized, the fan blade 4 is suspended and sleeved on the mirror barrel. At this time, the axis of the fan blade 4 coincides with the axis of the lens barrel 1. In short, through the cooperation of the third magnet ring 63 and the fourth magnet ring 64 , the fan blade 4 can b...

Abstract

The invention relates to the technical field of gun sight, in particular to a gun sight with demisting and dedusting functions. The gun sight with the demisting and dedusting functions comprises a lens cone, a lens and a demisting and dedusting module, and the lens is installed at the end of the lens cone; the lens cone is provided with a first ventilation groove and a second ventilation groove; and the demisting and dedusting module comprises an outer cover and a fan, the outer cover covers the lens cone and forms an accommodating space with the outer wall of the lens cone, the fan is rotatably arranged in the accommodating space, the fan is located between the first ventilation groove and the second ventilation groove, and the second ventilation groove is located on one side close to thelens. The fan can rotate so that gas in the lens cone can enter the accommodating space from the first ventilation groove and is blown to the lens through the second ventilation groove so as to remove mist and / or dust on the lens, the aiming accuracy of the gun sight can be improved, and the hit rate can be increased.

Description

technical field [0001] The invention relates to the technical field of gun sights, in particular to a gun sight with functions of removing fog and dust. Background technique [0002] The electronic gun scope is mainly used in various military guns. It has the functions of observation and aiming, and can improve the shooting rate. Due to the great changes in the ambient temperature in the field, the gun scope is prone to fogging and blurring. In addition, when used for a long time, dust is likely to fall on the scope of the gun, which brings more inconvenience to the user, seriously affects the accuracy, and reduces the shooting effect. [0003] Therefore, there is an urgent need for a gun sight with fog and dust removal functions to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a gun sight with the function of removing fog and dust, which can improve the aiming accuracy and hit rate. [0005] In order to a...
