Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes or to distinguish between different structures or components and should not be construed as indicating or implying relative importance.

[0053] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention.

[0054] Example 1

[0055] like Figure 1-2 As shown, this embodiment provides a gun sight with demisting and dust removal functions, including a lens barrel 1, a lens 2, and a demisting and dust removal module. The lens 2 is mounted at the end of the lens barrel 1. The lens barrel 1 is provided with a first ventilation slot 11 and a second ventilation slot 12. The demisting and dust removal module includes an outer cover 3 and a fan. The outer cover 3 is provided outside the lens barrel 1 and forms a storage space with the outer wall of the lens barrel 1. The fan is rotatably disposed in the storage space and is located between the first ventilation slot 11 and the second ventilation slot 12. The second ventilation slot 12 is located on a side close to the lens 2. The fan can rotate so that the air in the lens barrel 1 enters the storage space from the first ventilation slot 11 and is blown toward the lens 2 through the second ventilation slot 12 to remove fog and / or dust on the lens 2, thereby improving the aiming accuracy of the gun sight and increasing the hit rate.

[0056] Preferably, the accommodating space is annular and arranged along the circumference of the lens barrel 1, so that the fan is symmetrically arranged to avoid the asymmetric force of the fan, which causes the relative displacement of the components inside the lens barrel and reduces the accuracy of the lens; on the other hand, it also ensures the uniformity of dust and mist removal on the mirror surface, and the fan arranged on one side causes the water mist to diffuse to one side.

[0057] Optionally, the outer cover 3 and the lens barrel 1 are designed as separate, separate parts, and a sealing strip is provided between the connection between the outer cover 3 and the lens barrel 1 to increase the blowing intensity of the fan and enhance the dust and mist removal effect. In other embodiments, the outer cover 3 can also be integrally molded onto the lens barrel 1 using a secondary injection molding process. Of course, the connection between the outer cover 3 and the lens barrel 1 can also be in other forms, as long as it can ensure that the gas in the lens barrel 1 does not leak outside the outer cover 3 and improve the blowing intensity of the fan.

[0058] Furthermore, if Figure 1 As shown, lenses 2 are installed at both ends of the lens barrel 1, one of which is an eyepiece and the other is an objective lens. A defogging and dust removal module is installed near each lens 2 to defog and dust the eyepiece and objective lens respectively to improve aiming accuracy.

[0059] Exemplarily, the lens 2 serving as the objective lens is an optical lens, and the lens 2 serving as the eyepiece can be an optical lens or a CCD element.

[0060] Optionally, the rifle scope also includes an image capture element, located at the imaging end (i.e., the eyepiece observation end) of the rifle scope. This element is used to capture and output image data, facilitating the automatic aiming function of the rifle scope. Preferably, the demisting and dust removal module also includes a filter 5 for absorbing dust, and the filter 5 is disposed on the first ventilation slot 11. Specifically, the filter 5 blocks the first ventilation slot 11 to absorb dust from the air flowing through the first ventilation slot 11, preventing dust from adhering to the lens 2 and affecting aiming.

[0061] In other embodiments, the second ventilation slot 12 may be provided with a filter 5. Of course, both the first ventilation slot 11 and the second ventilation slot 12 may be provided with a filter 5 to improve the dust removal effect.

[0062] Optionally, a plurality of first ventilation slots 11 are arranged at intervals along the circumference of the lens barrel 1 to improve gas fluidity, allowing more gas to enter the accommodating space and blow toward the lens 2 from the second ventilation slots 12 to defog and remove dust from the lens 2.

[0063] Preferably, a plurality of second ventilation slots 12 are arranged at intervals along the circumference of the lens barrel 1 to blow air around the lens 2 for demisting and dust removal, thereby improving the demisting and dust removal efficiency.

[0064] Optionally, in order to reduce the resistance of gas entering the accommodating space and optimize the airflow circulation in the lens barrel 1, the extension direction of the first ventilation slot 11 is set at an angle to the outer wall of the lens barrel 1, and the first ventilation slot 11 faces the fan.

[0065] Furthermore, in order to improve the defogging and dust removal effect on the lens 2 and optimize the airflow circulation in the lens barrel 1, the extension direction of the second ventilation groove 12 is set at an angle to the outer wall of the lens barrel 1, and the second ventilation groove 12 is facing the lens, so that the gas from the accommodating space is blown toward the lens 2 along the second ventilation groove 12.

[0066] Preferably, the first ventilation slot 11 and the second ventilation slot 12 are symmetrically arranged on both sides of the fan.

[0067] Optionally, the fan is rotatably mounted on the lens barrel 1 to facilitate installation and support of the fan. In other embodiments, multiple independent small fans can be arranged at intervals along the circumference of the lens barrel 1. As long as air flow can be generated within the accommodation space and the lens barrel 1 and the air is blown toward the lens 2, no other restrictions are imposed here.

[0068] Preferably, the fan includes blades 4 and a driving assembly, and the driving assembly is disposed in the accommodating space and is capable of driving the blades 4 to rotate.

[0069] Alternatively, as Figure 3 As shown, the fan blade 4 includes a mounting ring 41 and blades 42. The mounting ring 41 is mounted on the lens barrel 1. A plurality of blades 42 are fixed to the mounting ring 41 at even intervals along the circumference of the mounting ring 41. The plurality of blades 42 are turbine-shaped. The turbine-shaped blades 42 can generate vortex wind, thereby improving the dust removal and dehumidification capabilities of the fan blade 4.

[0070] Furthermore, fan blade 4 includes an outer ring 43, which is coaxially arranged with mounting ring 41. The ends of blade 42 are fixedly connected to mounting ring 41 and outer ring 43, respectively. In other words, blade 42 is contained and not exposed. This prevents blade 42 from colliding or scraping against the wall of lens barrel 1 and electrical wiring during high-speed rotation, potentially breaking blade 42 and severing the electrical wiring. Furthermore, outer ring 43 also serves to limit the position of blade 42.

[0071] Furthermore, the gun sight with demisting and dust removal functions also includes a humidity sensor 8 and a controller 9. The humidity sensor 8 is arranged on the inner wall of the lens barrel 1 and is located on the side close to the lens 2. The humidity sensor 8 is used to detect the humidity inside the lens barrel 1; the controller 9 is communicated with the humidity sensor 8, and the controller 9 can control the fan blades 4 to rotate or stop rotating according to the detection results of the humidity sensor 8.

[0072] Preferably, humidity sensors 8 are provided around the two lenses 2, and a controller 9 is provided between the two demisting and dust removal modules and is in communication connection with the two demisting and dust removal modules, thereby controlling the operation of the two demisting and dust removal modules.

[0073] For example, the demisting and dust removal process for lens 2, which serves as the eyepiece, will be described. When humidity sensor 8 detects that the humidity near the eyepiece has reached a fogging threshold value D1, controller 9 receives this signal and issues a demisting and dust removal command to the drive assembly. The drive assembly then rotates fan blades 4, blowing air toward the eyepiece and creating air convection within the riflescope, thereby achieving demisting and dust removal. The demisting and dust removal process for lens 2, which serves as the objective lens, is similar and will not be further described here.

[0074] Example 2

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

[0076] like Figure 4 As shown, the fan blades 4 are rotatably mounted on the lens barrel 1 via bearings 7 to support the fan blades 4. In this case, the drive assembly includes a first magnet ring 61 and a second magnet ring 62. The first magnet ring 61 is disposed on the inner wall of the outer cover 3 and is coaxial with the lens barrel 1. The second magnet ring 62 is disposed on the fan blades 4 and is coaxial with the lens barrel 1. When the first magnet ring 61 is energized, the fan blades 4 can rotate relative to the lens barrel 1. Specifically, when the first magnet ring 61 and the second magnet ring 62 are energized, the magnetic fields they generate change, causing the second magnet ring 62 to rotate, thereby rotating the fan blades 4.

[0077] The drive assembly can make the fan blades 4 rotate silently and without vibration, and will not affect the accuracy of gun aiming.

[0078] Example 3

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

[0080] like Figure 5 As shown, the fan blade 4 is suspended and sleeved on the lens barrel 1. At this time, the driving assembly includes a third magnet ring 63 and a fourth magnet ring 64. The third magnet ring 63 is set on the outer wall of the lens barrel 1 and is coaxial with the lens barrel 1; the fourth magnet ring 64 is set on the wall of the mounting hole of the fan blade 4 and is coaxial 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 lens barrel 1. 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 be suspended and sleeved on the lens barrel 1.

[0081] Specifically, the outer magnetic poles of the first magnetic ring 61 and the inner magnetic poles of the fourth magnetic ring 64 are the same, so that the fan blades 4 are suspended on the lens barrel 1, that is, the first magnetic ring 61 and the fourth magnetic ring 64 can act as bearings, allowing the fan blades 4 to rotate smoothly.

[0082] Furthermore, the drive assembly includes a first magnet ring 61 and a second magnet ring 62. The first magnet ring 61 is disposed on the inner wall of the outer cover 3 and is coaxial with the lens barrel 1. The second magnet ring 62 is disposed on the fan blade 4 and is coaxial 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 ring 61 is energized, the magnetic field it generates changes, causing the second magnet ring 62 to rotate, thereby rotating the fan blade 4. In short, the cooperation between the first magnet ring 61 and the second magnet ring 62 causes the fan blade 4 to rotate.

[0083] Exemplarily, the fourth magnet ring 64 is a permanent magnet to ensure that the fourth magnet ring 64 can respond to the magnetic field changes of the third magnet ring 63 in real time.

[0084] The drive assembly can make the fan blades 4 rotate silently and without vibration, and will not affect the accuracy of gun aiming.

[0085] In other embodiments, in order to make the fan blade 4 suspended and mounted on the lens barrel 1, the driving component may also include a third powered coil and a permanent magnet ring, wherein the third powered coil is arranged on the outer wall of the lens barrel 1, and the third powered coil and the lens barrel 1 are coaxially arranged; the permanent magnet ring is arranged on the mounting hole wall of the mounting ring 41 of the fan blade 4, and is coaxially arranged with the lens barrel 1. When the third powered coil is energized, the inner magnetic pole of the third powered coil is made identical to the outer magnetic pole of the permanent magnet ring, so that the fan blade 4 is suspended and mounted on the lens barrel 1.

[0086] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
