[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example

[0033] like Figures 1-3 As shown, this utility model proposes a rigid gas permeable (RGP) lens cleaning device, including a waste liquid container 1. A cover plate 2 is fixedly installed on the top of the waste liquid container 1, and a cleaning cylinder 3 is fixedly installed on the upper surface of the cover plate 2. The waste liquid container 1 collects the waste liquid inside the cleaning cylinder 3, preventing the waste liquid from accumulating inside the cleaning cylinder 3. A second atomizing nozzle 8 is fixedly installed on the top of the cover plate 2 via a bracket. The second atomizing nozzle 8 is installed inside the cleaning cylinder 3, and a rubber support ring 9 is fixedly installed on the top of the second atomizing nozzle 8 via a bracket. The rubber support ring 9 supports the lens, ensuring that the lens can be placed on the cleaning cylinder 3. Inside; a cleaning hood 4 is inserted into the top of the cleaning cylinder 3. A first atomizing nozzle 6 is fixedly installed on the inner top wall of the cleaning hood 4 via a bracket. A rubber pressing ring 7 is fixedly installed at the bottom of the first atomizing nozzle 6 via a bracket. The rubber pressing ring 7 covers the top of the rubber support ring 9 and can press and position the edge of the lens to ensure that the lens can be stably mounted inside the cleaning cylinder 3 and prevent it from falling off during cleaning. The convex surface of the lens is rinsed by the first atomizing nozzle 6, and the concave surface of the lens is rinsed by the second atomizing nozzle 8, ensuring that both sides of the lens can be effectively cleaned.

[0034] like Figures 1-3As shown, to facilitate water supply to the two atomizing nozzles, a first water inlet pipe 61 is fixedly installed on the first atomizing nozzle 6. One end of the first water inlet pipe 61 passes through the cleaning hood 4 and extends to its outside. A water guide hose 5 is fixedly installed at the end of the first water inlet pipe 61 away from the first atomizing nozzle 6. A second water inlet pipe 81 is fixedly installed on the second atomizing nozzle 8. One end of the second water inlet pipe 81 passes through the cleaning cylinder 3 and extends to its outside. The second water inlet pipe 81 is a T-connector. An external water supply pipe is connected to the end of the second water inlet pipe 81 away from the second atomizing nozzle 8. The water guide hose 5 is inserted into the branch port on the second water inlet pipe 81. When the external water supply pipe inputs cleaning fluid into the second water inlet pipe 81, part of the cleaning fluid enters the second atomizing nozzle 8, and the other part of the cleaning fluid enters the first atomizing nozzle 6 along the water guide hose 5 and the first water inlet pipe 61. This achieves synchronous water supply to the two atomizing nozzles and effectively improves the convenience of cleaning fluid supply.

[0035] Secondly, to facilitate the removal of the cleaning cover 4 from the cleaning cylinder 3, a water guide hose 5 is used as the connecting pipe between the first water inlet pipe 61 and the second water inlet pipe 81. When it is necessary to remove the cleaning cover 4 from the top of the cleaning cylinder 3, the end of the water guide hose 5 away from the first water inlet pipe 61 is first pulled off from the branch pipe port on the second water inlet pipe 81. During the process of pulling the cleaning cover 4 upward, the water guide hose 5 can prevent the cleaning cover 4 from being restricted in its upward movement distance, effectively improving the convenience of disassembling the cleaning cover 4.

[0036] like Figure 5 and Figure 6 As shown, after the lens is clamped and positioned, in order to prevent damage to the lens, an annular limiting groove 92 is chiseled on the top of the rubber support ring 9. A second arc-shaped surface 91 is provided at the opening of the annular limiting groove 92. During the process of the edge of the lens being inserted into the annular limiting groove 92, the convex surface of the lens contacts the opening of the annular limiting groove 92. At this time, the second arc-shaped surface 91 can prevent the convex surface of the lens from being scratched. The bottom opening of the rubber pressing ring 7 is provided with a first arc-shaped surface 71. When the rubber pressing ring 7 presses on the convex surface of the lens, the arc design of the first arc-shaped surface 71 can avoid indentation on the lens, thus preventing damage to the lens after clamping and effectively improving the protection effect of the lens.

[0037] like Figure 3 and Figure 4As shown, to facilitate the collection and discharge of cleaning waste liquid, several leakage holes 21 are drilled in the cover plate 2. The waste cleaning liquid after cleaning the lens gathers at the bottom of the cleaning cylinder 3 and then falls into the waste liquid box 1 through the leakage holes 21. The bottom of the waste liquid box 1 has a drain port 11, and a rubber plug 12 is tightly inserted into the drain port 11. During the lens cleaning process, the drain port 11 is sealed by the rubber plug 12 to prevent the waste liquid inside the waste liquid box 1 from leaking out. After the lens cleaning is completed, the device is lifted upward and the rubber plug 12 is pulled out to discharge the waste liquid collected inside the waste liquid box 1, which effectively improves the convenience of collecting and discharging cleaning waste liquid.

[0038] like Figure 1 and Figure 3 As shown, in order to improve the stability of the cleaning hood 4 after installation, an annular support plate 31 is fixedly installed on the inner wall of the cleaning cylinder 3. When the bottom end of the cleaning hood 4 is inserted into the cleaning cylinder 3, the bottom of the cleaning cylinder 3 contacts the upper surface of the annular support plate 31. The annular support plate 31 supports the cleaning hood 4 and prevents it from sliding down, effectively improving the stability of the cleaning hood 4 after installation.

[0039] In this embodiment, the lens is first clamped and positioned by using a suction stick to hold the convex middle area of ​​the lens and placing the lens on the rubber support ring 9. Once the edge of the lens is embedded in the annular limiting groove 92, the suction stick is released to prevent the lens from wobbling horizontally. Then, the cleaning cover 4 is inserted into the top of the cleaning cylinder 3. At this time, the rubber pressing ring 7 contacts the rubber support ring 9. The rubber pressing ring 7 presses and positions the convex edge of the lens to prevent the lens from moving vertically, ensuring that the lens can be stably installed inside the cleaning cylinder 3. This not only ensures the stability of the lens after installation but also simplifies the operation.

[0040] After the lens is fixed, the end of the water-conducting hose 5 away from the first water inlet pipe 61 is inserted into the branch pipe port on the second water inlet pipe 81. The external water supply pipe is inserted into the inlet end of the second water inlet pipe 81. The inlet port of the external water supply pipe is fixed at the outlet port of the low-pressure pump (the external water supply pipe and the low-pressure pump are existing technologies and are not shown in the figure, so they will not be described in detail here). The cleaning fluid is delivered to the two atomizing nozzles through the low-pressure pump. The convex surface of the lens is rinsed by the first atomizing nozzle 6, and the concave surface of the lens is rinsed by the second atomizing nozzle 8, ensuring that both sides of the lens are effectively cleaned. The overall structure of this cleaning device is simple and easy to disassemble and assemble. When the internal structure of the device malfunctions, it is convenient to repair, which effectively reduces maintenance costs.

[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
