Description

Technical Field

[0001] This invention relates to the field of optical lens technology, and more particularly to a heat-exchange optical lens. Background Technology

[0002] An optical lens is a common optical element in the field of optics, typically composed of lenses. It is primarily used to collect or focus incident light rays, altering the direction, speed, and phase of light transmission, thereby achieving control and adjustment of light. Based on their shape and function, optical lenses can be classified into various types, including plano-convex lenses, convex lenses, plano-concave lenses, concave lenses, biconvex lenses, and biconcave lenses. Optical lenses have wide applications in photography, medicine, astronomy, military, and scientific research. For example, in photography, adjusting the lens position changes the focal length of the image, enabling clear imaging of objects at different distances. In astronomy, the design of telescopes often involves the combined use of multiple optical lenses to enhance imaging results.

[0003] Existing optical lenses are prone to moisture adhesion on their surface due to varying usage and storage environments, which affects their performance. Furthermore, the uncontrollable ambient temperature makes it difficult for moisture to dissipate quickly, causing it to remain on the lens surface for extended periods. Additionally, the complex internal structure of optical lenses, which require adjustment of their position, makes disassembly and cleaning difficult, thus hindering their defogging and de-fogging capabilities. Summary of the Invention

[0004] To address the technical problem that existing optical lenses are not convenient for defogging, this invention proposes a heat-exchange optical lens.

[0005] This invention proposes a heat-exchange optical lens, comprising a lens group with focusing function and a lens housing with adjusting function. The surface of the lens group is mounted inside the lens housing, and a heating device is mounted on the outer surface of the lens group. In use, the heating device heats up, and the high temperature is transferred to the surface of the lens group. A ventilation device is mounted on the surface of the heating device. In use, the ventilation device rotates within the heating device and drives the airflow within the heating device. A cleaning device is mounted on the surface of the heating device. In use, the cleaning device guides away oil stains from the surface of the heating device.

[0006] Preferably, the heating device includes an electric heating coil, a connecting post is fixedly connected to the inner wall surface of the electric heating coil, and a heat-conducting ring is fixedly connected to the end surface of the connecting post. The heat-conducting ring and the connecting post are both made of copper. The inner wall surface of the heat-conducting ring is fixedly sleeved with the outer surface of the lens assembly.

[0007] The above technical solution utilizes an electric heating coil to exchange heat with the lens assembly through a heat-conducting ring and connecting column, thereby facilitating the heating of the lens assembly by the electric heating coil.

[0008] Preferably, a limiting ring is fixedly connected to the side wall surface of the heat-conducting ring. The limiting ring has an L-shaped cross-section. A connecting block is fixedly connected to the upper surface of two adjacent limiting rings. The upper surface of the connecting block is inclined. The connecting block is located between the electric heating coil and the heat-conducting ring. Multiple connecting blocks are arranged in a ring array on the surface of the limiting ring with the axis of the limiting ring as the array center.

[0009] The above technical solution utilizes two limiting rings and a heat-conducting ring in a concave shape to install and place the electric heating coil, thereby facilitating the collection of oil stains from the electric heating coil through the concavity on the surface of the limiting rings.

[0010] Preferably, a heat preservation box is fixedly sleeved on the outer surface of the lens group. The heat preservation box is circular in shape, the electric heating coil is located inside the heat preservation box, and a ventilation opening is provided on the outer surface of the heat preservation box.

[0011] By using the above technical solution, the electric heating coil is wrapped in an insulated box, which not only protects it but also reduces the rate of heat loss from the electric heating coil and improves the heating efficiency of the lens assembly.

[0012] Preferably, the ventilation device includes a fan blade, a baffle is fixedly connected to the outer surface of the fan blade, the side wall of the baffle is fan-shaped, and mounting rings are fixedly connected to both sides of the baffle. Multiple baffles are arranged in a ring array on the surface of the mounting ring with the axis of the mounting ring as the array center.

[0013] The above technical solution utilizes a baffle for installation, aligning the distribution of the baffle on the mounting ring surface with the distribution of the ventilation openings on the insulation box surface. This facilitates the baffle's coverage of the ventilation openings, preventing external debris from entering the insulation box.

[0014] Preferably, the surfaces of the two mounting rings are rotatably connected to the two inner sidewall surfaces of the insulation box via bearings, and an internal gear is fixedly sleeved on the inner sidewall of one of the mounting rings, while a drive motor is fixedly connected to the outer surface of the insulation box.

[0015] The above technical solution utilizes the installation ring to be installed by moving it through the inner wall of the insulation box, thereby facilitating the rotation of the installation ring inside the insulation box.

[0016] Preferably, a drive gear is fixedly sleeved on the output shaft surface of the drive motor, the drive gear is located inside the insulation box, and the surface of the drive gear meshes with the inner wall surface of the internal gear.

[0017] The above technical solution utilizes a drive motor to provide power for the rotation of the drive gear, thereby facilitating the drive gear to drive the internal gear to rotate.

[0018] Preferably, the cleaning device includes a guide plate with a triangular cross-section, the guide plate is located on the surface of the connecting block, and a collection plate is fixedly connected to one end surface of the guide plate.

[0019] The above technical solution uses a guide plate to remove oil stains from the surface of the connecting block, which facilitates the adhesion of oil stains to the surface of the guide plate. When the guide plate rotates, the centrifugal force guides the oil stains to slide on the surface of the guide plate.

[0020] Preferably, the surface of the collecting plate is provided with a collecting groove, and an absorbent block is fixedly connected to the inner wall of the collecting groove. The absorbent block is made of oil-absorbing ceramic.

[0021] The above technical solution utilizes oil-absorbing ceramics to absorb oil stains that slide across the surface of the guide plate, thereby facilitating the collection of oil stains generated by the electric heating coil.

[0022] Preferably, an external gear is fixedly connected to the outer surface of the collecting plate, the side wall surface of the external gear is rotatably connected to the inner wall of the insulation box, and the surface of the external gear meshes with the surface of the driving gear.

[0023] The above technical solution utilizes an external gear that is rotatably connected to the inner wall of the insulation box via a bearing. The external gear is connected to the drive gear and the collecting plate, thereby facilitating the rotation of the guide plate by the collecting plate.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. By installing a heating device on the surface of a traditional optical lens, the electric heating coil in the heating device is activated to heat the lens group in the optical lens. The heat is then transferred to the surface of the lens group through a heat-conducting ring, causing the water vapor on the surface of the lens group to evaporate. This avoids the adhesion of water vapor and its impact on the use of the lens group, thus making the heating device convenient for heating and defogging the optical lens.

[0026] 2. By installing a ventilation device inside the heating device, the fan blades in the ventilation device are driven by a motor and rotate inside the insulation box, which promotes the air circulation inside the insulation box. This allows the moisture inside the insulation box to escape quickly, while reducing the frequency of use of the electric heating coil, saving energy, and avoiding overheating inside the insulation box caused by long-term use of the electric heating coil. Thus, the ventilation device has the characteristic of facilitating ventilation inside the heating device.

[0027] 3. By installing a cleaning device inside the heating device, the guide plate in the cleaning device rotates together with the fan blades in the ventilation device, causing the guide plate to hang the oil stains on the surface of the connecting block. This makes it easier for the oil stains to adhere to the surface of the guide plate. When the guide plate rotates, centrifugal force guides the oil stains to slide on the surface of the guide plate and be absorbed by the absorption block in the collection tank. This avoids the oil stains generated when the electric heating coil is used from contaminating the lens assembly, thus making the cleaning device easy to maintain the cleanliness inside the heating device.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Reference Figures 1-7A heat exchange optical lens includes a lens group 1 with focusing function and a lens housing 2 with adjusting function. The surface of the lens group 1 is installed inside the lens housing 2. A heating device 3 is installed on the outer surface of the lens group 1. In use, the heating device 3 heats up, and the high temperature is transferred to the surface of the lens group 1. A ventilation device 4 is installed on the surface of the heating device 3. In use, the ventilation device 4 rotates inside the heating device 3 and drives the airflow inside the heating device 3. A cleaning device 5 is installed on the surface of the heating device 3. In use, the cleaning device 5 guides the oil stains on the surface of the heating device 3.

[0038] To heat the lens assembly 1, a heating device 3 is provided, including an electric heating coil 31. A connecting post 32 is fixedly connected to the inner wall surface of the electric heating coil 31, and a heat-conducting ring 33 is fixedly connected to the end surface of the connecting post 32. The heat-conducting ring 33 and the connecting post 32 are both made of copper. The inner wall surface of the heat-conducting ring 33 is fixedly sleeved with the outer surface of the lens assembly 1. The electric heating coil 31 exchanges heat with the lens assembly 1 through the heat-conducting ring 33 and the connecting post 32, thereby facilitating the heating of the lens assembly 1 by the electric heating coil 31. The side wall surface of the heat-conducting ring 33 is fixedly connected to... A limiting ring 34 is connected, and the cross-section of the limiting ring 34 is L-shaped. A connecting block 35 is fixedly connected to the upper surface of two adjacent limiting rings 34. The upper surface of the connecting block 35 is inclined. The connecting block 35 is located between the electric heating coil 31 and the heat conducting ring 33. Multiple connecting blocks 35 are arranged in a ring array on the surface of the limiting ring 34 with the axis of the limiting ring 34 as the array center. The electric heating coil 31 is installed and placed by combining two limiting rings 34 and the heat conducting ring 33 in a concave shape, so as to facilitate the collection of oil stains on the electric heating coil 31 through the concavity on the surface of the limiting ring 34.

[0039] To improve the heating efficiency of the heating device 3, a heat preservation box 36 is fixedly sleeved on the outer surface of the lens group 1. The heat preservation box 36 is in the shape of a ring, and the electric heating coil 31 is located inside the heat preservation box 36. A ventilation hole 37 is opened on the outer surface of the heat preservation box 36. The heat preservation box 36 is used to wrap the electric heating coil 31, so that while the electric heating coil 31 is wrapped and protected by the heat preservation box 36, the heat loss rate of the electric heating coil 31 is reduced, thereby improving the heating efficiency of the lens group 1.

[0040] By installing a heating device 3 on the surface of a conventional optical lens, the electric heating coil 31 in the heating device 3 is activated to heat the lens group 1 in the optical lens. The heat is then transferred to the surface of the lens group 1 through the heat conduction ring 33, so that the water vapor on the surface of the lens group 1 is heated and evaporated, avoiding the adhesion of water vapor and affecting the use of the lens group 1. Thus, the heating device 3 has the characteristic of facilitating the heating and defogging of the optical lens.

[0041] To ventilate the interior of the insulation box 36, a ventilation device 4 is provided, including a fan blade 41. A baffle 42 is fixedly connected to the outer surface of the fan blade 41. The side wall of the baffle 42 is fan-shaped, and mounting rings 43 are fixedly connected to both sides of the baffle 42. Multiple baffles 42 are arranged in a ring array on the surface of the mounting ring 43 with the axis of the mounting ring 43 as the array center. The fan blade 41 is installed through the baffle 42, and the distribution of the baffles 42 on the surface of the mounting ring 43 is aligned with the distribution of the ventilation openings 37 on the surface of the insulation box 36. This facilitates the blocking of the opening surface of the ventilation openings 37 by the baffles 42, preventing external debris from entering the interior of the insulation box 36.

[0042] To drive the fan blade 41, the surfaces of two mounting rings 43 are rotatably connected to the two inner sidewalls of the insulation box 36 via bearings. An internal gear 44 is fixedly sleeved on the inner sidewall of one of the mounting rings 43. A drive motor 45 is fixedly connected to the outer surface of the insulation box 36. The mounting ring 43 is movably mounted through the inner wall of the insulation box 36, which facilitates the rotation of the mounting ring 43 inside the insulation box 36. A drive gear 46 is fixedly sleeved on the output shaft surface of the drive motor 45. The drive gear 46 is located inside the insulation box 36, and its surface meshes with the inner wall surface of the internal gear 44. The drive motor 45 provides power for the rotation of the drive gear 46, which in turn drives the internal gear 44 to rotate.

[0043] By installing a ventilation device 4 inside the heating device 3, the fan blades 41 in the ventilation device 4 are driven by the drive motor 45 and rotate inside the insulation box 36, which promotes the air circulation inside the insulation box 36. This allows the moisture inside the insulation box 36 to escape quickly, while reducing the frequency of use of the electric heating coil 31, saving energy, and avoiding overheating inside the insulation box 36 due to long-term use of the electric heating coil 31. Thus, the ventilation device 4 has the characteristic of facilitating ventilation inside the heating device 3.

[0044] To clean the inside of the insulation box 36, a cleaning device 5 is provided, including a guide plate 51. The guide plate 51 has a triangular cross-section and is located on the surface of the connecting block 35. A collection plate 52 is fixedly connected to one end of the guide plate 51. The guide plate 51 is used to hang the oil stains on the surface of the connecting block 35, so that the oil stains can adhere to the surface of the guide plate 51. When the guide plate 51 rotates, the oil stains are guided to slide on the surface of the guide plate 51 through centrifugal force.

[0045] To collect oil stains, a collection groove 53 is provided on the surface of the collection plate 52. An absorbent block 54 is fixedly connected to the inner wall of the collection groove 53. The absorbent block 54 is made of oil-absorbing ceramic. The oil-absorbing ceramic absorbs the oil stains that slide across the surface of the guide plate 51, thereby facilitating the collection of oil stains generated by the electric heating coil 31. An external gear 55 is fixedly connected to the outer surface of the collection plate 52. The side wall surface of the external gear 55 is rotatably connected to the inner wall of the heat preservation box 36. The surface of the external gear 55 meshes with the surface of the drive gear 46. The external gear 55 connects the drive gear 46 and the collection plate 52, thereby facilitating the rotation of the guide plate 51 by the collection plate 52.

[0046] By installing a cleaning device 5 inside the heating device 3, the guide plate 51 in the cleaning device 5 rotates together with the fan blade 41 in the ventilation device 4, causing the guide plate 51 to hang the oil stains on the surface of the connecting block 35. This makes it easier for the oil stains to adhere to the surface of the guide plate 51. When the guide plate 51 rotates, the centrifugal force guides the oil stains to slide on the surface of the guide plate 51 and be absorbed by the absorption block 54 in the collection tank 53. This avoids the oil stains generated when the electric heating coil 31 is used from contaminating the lens assembly 1, thus making the cleaning device 5 easy to maintain the cleanliness inside the heating device 3.

[0047] Working principle:

[0048] When in use, start the drive motor 45. The drive motor 45 drives the internal gear 44 to rotate through the drive gear 46. The internal gear 44 drives the baffle 42 to rotate through the mounting ring 43. When the baffle 42 blocks the ventilation opening 37, stop the drive motor 45.

[0049] When there is a small amount of water vapor in the lens group 1, the drive motor 45 is started. The drive motor 45 drives the internal gear 44 to rotate through the drive gear 46. The internal gear 44 drives the baffle 42 and the fan blade 41 to rotate through the mounting ring 43. The fan blade 41 blows the airflow in the heat preservation box 36. Under the action of the fan blade 41, the water vapor in the heat preservation box 36 flows out through the vent 37.

[0050] When there is too much water vapor in the lens group 1, the vent 37 is blocked by the baffle 42, so that the heat preservation box 36 is sealed and the electric heating coil 31 is activated. The electric heating coil 31 transfers heat to the surface of the lens group 1 through the heat-conducting column and the heat-conducting ring 33, and the water vapor in the lens group 1 evaporates due to the heat.

[0051] After use, start the drive motor 45. The drive motor 45 drives the external gear 55 to rotate through the drive gear 46. The external gear 55 drives the guide plate 51 to slide on the surface of the connecting block 35 through the collection plate 52. The guide plate 51 hangs the oil on the surface of the connecting block 35. The oil adheres to the surface of the guide plate 51. When the guide plate 51 rotates, the centrifugal force guides the oil to slide on the surface of the guide plate 51. The absorption block 54 in the collection tank 53 absorbs the oil that slides on the surface of the guide plate 51.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
