Description

Technical Field

[0001] The utility model relates to the technical field of lens cleaning, and particularly relates to a lens cleaning device. Background Art

[0002] The lens is a key component in optical equipment, and its surface cleanliness directly affects the imaging quality and equipment performance. During daily use, the lens surface is prone to being contaminated by impurities such as dust, fingerprints, and oil stains. These contaminants not only reduce the light transmittance but may also cause image blurring, contrast reduction, and even damage the lens coating in the case of long-term accumulation. Therefore, regular cleaning and maintenance of the lens are necessary measures to maintain the best performance of optical equipment.

[0003] Existing lens cleaning devices usually adopt a fixed support structure to hold the lens to be cleaned and use ultrasonic or mechanical wiping methods for cleaning. However, this fixed support structure has a significant defect: the positions where the support structure contacts the lens often form cleaning dead corners and cannot be effectively cleaned. These uncleaned areas not only affect the overall cleaning effect but may also become the source of pollutant accumulation and affect the long-term use performance of the lens. In addition, in order to clean these dead corners, it is often necessary to manually adjust the lens position or replace the support structure, which greatly increases the operation complexity and time cost. Summary of the Utility Model

[0004] The main object of the utility model is to propose a lens cleaning device, aiming to solve the technical problem that the existing lens cleaning device has dead corners when cleaning the lens.

[0005] To achieve the above object, the lens cleaning device proposed by the utility model includes a housing and a support assembly;

[0006] A cleaning cavity is provided inside the housing;

[0007] The support assembly includes a first support member and a second support member provided in the cleaning cavity, and at least one of the first support member and the second support member is movably provided in the cleaning cavity; wherein, the first support member and the second support member are used to alternately support the lens to be cleaned, and the contact positions of the first support member and the second support member with the lens to be cleaned do not overlap each other.

[0008] In some embodiments, the first support member includes a first supporting portion fixed in the cleaning cavity, the second support member includes a lifting portion and a second supporting portion, the lifting portion is connected to the second supporting portion and is configured to drive the second supporting portion to move up and down, so that the second supporting portion can reciprocate between above and below the first supporting portion; wherein, when the second supporting portion is located above the first supporting portion, the second supporting portion is configured to support the lens to be cleaned; when the second supporting portion is located below the first supporting portion, the first supporting portion is configured to support the lens to be cleaned.

[0009] In some embodiments, the first supporting portion is provided with a moving avoidance hole;

[0010] The cross-section of the second supporting portion is circular, the diameter of the second supporting portion is smaller than the diameter of the moving avoidance hole, and the second supporting portion moves up and down inside the inner side of the peripheral wall of the moving avoidance hole.

[0011] In some embodiments, the moving avoidance hole is centrally arranged on the first supporting portion.

[0012] In some embodiments, an annular flexible pad is arranged on the peripheral wall of the moving avoidance hole, and the inner diameter of the annular flexible pad is larger than the diameter of the second supporting portion.

[0013] In some embodiments, the first supporting portion is a first supporting mesh;

[0014] The second supporting portion is a second supporting mesh.

[0015] In some embodiments, the lens cleaning device further includes an ultrasonic generator arranged in the cleaning cavity, and the ultrasonic generator is configured to transmit ultrasonic waves to the cleaning liquid in the cleaning cavity.

[0016] The lens cleaning device of the present invention has the following advantages:

[0017] At least one of the first support member and the second support member in the support assembly is movable, which breaks through the limitations of the traditional fixed support structure.

[0018] This design not only eliminates the cleaning dead corners, but also brings additional advantages. It realizes the automation of the cleaning process, without the need for manual adjustment of the lens position, greatly reducing the operation complexity and time cost. At the same time, due to the dynamic change of the support position, the risk of damage to the lens caused by long-term fixed support is also reduced. Brief Description of the Drawings

[0029] The present utility model provides a lens cleaning device.

[0030] In an embodiment of the present utility model, as Figures 1 to 3 shown, the lens cleaning device includes a housing 1 and a support assembly 2;

[0031] A cleaning cavity 11 is provided inside the housing 1;

[0032] The support assembly 2 includes a first support member 21 and a second support member 22 disposed inside the cleaning cavity 11, and at least one of the first support member 21 and the second support member 22 is movably disposed inside the cleaning cavity 11; wherein, the first support member 21 and the second support member 22 are used to alternately support the lens to be cleaned, and the contact positions of the first support member 21 and the second support member 22 with the lens to be cleaned do not overlap each other.

[0033] Specifically, the housing 1 is the external structure of the entire device, which plays a role in protecting and accommodating internal components. A cleaning cavity 11 is provided inside the housing 1, and this cleaning cavity 11 is the space where the lens is actually cleaned. The cleaning cavity 11 can accommodate cleaning liquid and the lens to be cleaned (abbreviated as the lens in some descriptions below).

[0034] The main functions of the first support member 21 and the second support member 22 are to alternately support the lens to be cleaned. This means that during the cleaning process, the lens will be supported by these two support members in turn. More specifically, when the first support member 21 supports the lens, the second support member 22 is in a state away from the lens; when the second support member 22 supports the lens, the first support member 21 is in a state away from the lens. This alternating support method ensures that every part of the lens can be fully cleaned.

[0035] The contact positions of the first support member 21 and the second support member 22 with the lens to be cleaned do not overlap. This means that the position where the first support member 21 contacts the lens will not be blocked when the second support member 22 supports the lens, and vice versa. This design further ensures that every area of the lens surface can be cleaned, avoiding the generation of cleaning dead corners.

[0036] In practical applications, the structures of the first support member 21 and the second support member 22 for supporting the lens can have various specific embodiments. For example, they can be a mesh structure, an array composed of multiple support points, a planar structure, a ring structure, etc. The movable support member (the first support member 21 or the second support member 22) can be moved through various mechanisms, such as a lifting mechanism driven by a motor, a pneumatic or hydraulic system, etc.

[0037] The advantages of this design are that it cleverly solves the problem of cleaning dead corners caused by traditional fixed support structures, achieving comprehensive and uniform cleaning of the lens. Through the alternating operation and movable design of the support members, this device not only improves the cleaning efficiency, but also simplifies the operation process and reduces the need for manual intervention. At the same time, due to the dynamic change of the support position, the risk of damage to the lens caused by long-term fixed support is also reduced, improving the safety of the cleaning process. Generally speaking, this innovative design of the support assembly 2 brings substantial improvements to the lens cleaning technology, both improving the cleaning effect and enhancing the convenience and safety of the operation.

[0038] In some embodiments, the first support member 21 includes a first supporting portion 211 fixed in the cleaning cavity 11, the second support member 22 includes a lifting portion 221 and a second supporting portion 222, the lifting portion 221 is connected to the second supporting portion 222 and is used to drive the second supporting portion 222 to move up and down, so that the second supporting portion 222 can reciprocate between above and below the first supporting portion 211; wherein, when the second supporting portion 222 is located above the first supporting portion 211, the second supporting portion 222 is used to support the lens to be cleaned; when the second supporting portion 222 is located below the first supporting portion 211, the first supporting portion 211 is used to support the lens to be cleaned.

[0039] Specifically, "moving up and down" can be understood as a reciprocating motion in the height direction of the housing 1.

[0040] The lifting portion 221 is connected to the second supporting portion 222, and its main function is to drive the second supporting portion 222 to reciprocate between above and below the first supporting portion 211. This reciprocating motion is the key to realizing alternating support. In practical applications, the lifting portion 221 can adopt various forms, such as an electric push rod, a cylinder, a hydraulic cylinder or other types of driving devices.

[0041] When the second supporting part 222 is located above the first supporting part 211, it undertakes the task of supporting the lens to be cleaned. In this state, the lens is mainly supported by the second supporting part 222, and the first supporting part 211 does not contact the lens. This allows the cleaning liquid and the cleaning force to contact the area originally shielded by the first supporting part 211.

[0042] Conversely, when the second supporting part 222 is located below the first supporting part 211, the supporting task is transferred to the first supporting part 211. At this time, the first supporting part 211 supports the lens to be cleaned, and the second supporting part 222 does not contact the lens. In this way, the area originally shielded by the second supporting part 222 can now be cleaned.

[0043] In specific implementation, the first supporting part 211 and the second supporting part 222 can adopt various forms, such as a flat support plate, a mesh structure, or a multi-point support array, etc. The moving range and speed of the lifting part 221 can be adjusted according to actual needs to adapt to lenses of different sizes and weights.

[0044] It can be understood that compared with the implementation mode where both the first supporting part 211 and the second supporting part 222 move, by fixing the first supporting part 211 and only moving the second supporting part 222, this design first ensures the stability of the system. The fixed first supporting part 211 provides a reliable reference plane for the entire cleaning process. At the same time, the design of a single moving part significantly simplifies the mechanical structure, not only reducing the manufacturing and maintenance costs, but also improving the reliability of the device. In addition, this design also simplifies the control system, reduces energy consumption, and makes the device more energy-efficient and efficient.

[0045] In some embodiments, the first supporting part 211 is provided with a moving avoidance hole 211a;

[0046] The cross-section of the second supporting part 222 is circularly arranged, the diameter of the second supporting part 222 is set to be smaller than the diameter of the moving avoidance hole 211a, and the second supporting part 222 moves up and down inside the peripheral wall of the moving avoidance hole 211a.

[0047] Specifically, the main function of the moving avoidance hole 211a is to provide space for the movement of the second supporting part 222. By setting this hole, the second supporting part 222 can move freely between the upper and lower sides of the first supporting part 211 without interfering with the first supporting part 211.

[0048] A moving avoidance hole 211a is provided for the second supporting part 222 to move. Compared with the second supporting part 222 rising to support the lens on the peripheral side of the first supporting part 211, it has the following remarkable advantages: First of all, this design allows the user to stably place the lens on the first supporting part 211, and the moving avoidance hole 211a is located directly below the lens. This layout enables the first supporting part 211 to be designed much larger than the lens size, providing a larger and more stable supporting plane for the lens. The user only needs to ensure that the lens covers the moving avoidance hole 211a, without the need for precise alignment, greatly simplifying the lens placement process. Secondly, when the second supporting part 222 rises, it can directly lift the lens through the moving avoidance hole 211a. This direct vertical rising movement ensures that the lens is evenly stressed, avoiding the risk of tilting or shaking. In contrast, if the second supporting part 222 rises from the periphery of the first supporting part 211, the lens must be partially suspended on the peripheral side of the first supporting part 211, which not only increases the instability of lens placement but also may cause uneven stress on the lens edge. Moreover, this design enhances the adaptability to lenses of different sizes. Regardless of the lens size, as long as it can cover the moving avoidance hole 211a, it can be effectively supported and cleaned. This flexibility enables the device to adapt to various specifications of lenses, improving its versatility.

[0049] In some embodiments, the moving avoidance hole 211a is centrally arranged on the first supporting part 211. It can be understood that centrally arranging the moving avoidance hole 211a on the first supporting part 211 has the following remarkable advantages compared with non - central arrangement: First of all, the centrally arranged moving avoidance hole 211a enables the first supporting part 211 to support the lens more evenly. When the lens is placed on the first supporting part 211, its weight will be evenly distributed around the moving avoidance hole 211a. This evenly distributed supporting force reduces the risk of uneven stress on the lens edge, especially for large - size or heavy - weight lenses. Secondly, the centrally located moving avoidance hole 211a provides the best rising path for the second supporting part 222. When the second supporting part 222 rises, it can accurately align with the center position of the lens. This central alignment ensures that during the support conversion process, the force transmission is more balanced, further reducing the possibility of the lens tilting or shaking. In contrast, if the moving avoidance hole 211a is located in a non - central position, it may lead to uneven supporting force and increase the risk of lens position deviation during the cleaning process.

[0050] Moreover, central arrangement simplifies user operation. When placing the lens, the user only needs to place the lens roughly in the center of the first supporting part 211, without considering the relative position between the lens and the moving avoidance hole 211a. This intuitive operation method reduces the use difficulty and the possibility of incorrect placement.

[0051] In some embodiments, an annular flexible pad 212 is provided on the peripheral wall of the moving avoidance hole 211a, and the inner diameter of the annular flexible pad 212 is set to be larger than the diameter of the second supporting portion 222.

[0052] The material of the annular flexible pad 212 can be selected from materials with certain elasticity and flexibility, such as rubber, silica gel or sponge. This kind of material can provide moderate deformation ability while maintaining its shape.

[0053] When the second supporting portion 222 moves, if there is slight shaking or deviation, it will contact the annular flexible pad 212. The contact of the annular flexible pad 212 can absorb some tiny vibrations, greatly reducing the running noise and improving the sound insulation performance of the device. At the same time, the annular flexible pad 212 can also prevent direct contact and possible wear between the first supporting portion 211 and the second supporting portion 222.

[0054] In some embodiments, the first supporting portion 211 is a first supporting net;

[0055] The second supporting portion 222 is a second supporting net.

[0056] Specifically, the mesh structure allows the cleaning liquid to flow freely, ensuring that the cleaning liquid can contact the surface of the lens. This greatly improves the comprehensiveness and efficiency of cleaning and avoids the generation of cleaning dead corners. Secondly, the actual contact area between the mesh structure and the lens is small, which not only reduces the potential pressure on the lens surface but also reduces the risk of scratches that may be caused during the cleaning process. In addition, the mesh structure has a certain flexibility, which can better adapt to the lens surfaces with different curvatures and provide more uniform support. Finally, compared with the solid structure, the mesh design greatly reduces the weight of the supporting portion, which is beneficial to improving the moving speed and accuracy of the second supporting portion 222 and reducing the energy consumption at the same time.

[0057] In some embodiments, the lens cleaning device further includes an ultrasonic generator 3 disposed in the cleaning cavity 11, and the ultrasonic generator 3 is used to transmit ultrasonic waves to the cleaning liquid in the cleaning cavity 11.

[0058] It can be understood that compared with cleaning methods such as pure mechanical wiping and high-pressure spraying, ultrasonic waves can generate cavitation bubbles at the microscopic level. The impact force generated when these bubbles burst can effectively remove stubborn stains on the lens surface, achieving the effect of deep cleaning. Moreover, ultrasonic cleaning is applicable to various lens materials and shapes, and there is no need to replace cleaning tools for different lenses.

[0059] In specific implementation, the ultrasonic generator 3 can be a piezoelectric ceramic transducer, a magnetostrictive transducer, a plate transducer, an immersion transducer, an external transducer, etc. Specifically, the waterproof ultrasonic transducer (such as a piezoelectric ceramic transducer) is directly immersed in the cleaning liquid in the cleaning cavity 11. The ultrasonic generator 3 can convert electrical energy into high-frequency mechanical vibrations, and these vibrations are transmitted through the cleaning liquid to form tiny bubbles in the liquid. These bubbles rapidly expand and collapse, generating local high pressure and high temperature, thereby "scouring" the lens surface at the microscopic level and effectively removing dirt.

[0060] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
