[0028] The lens cleaning device of the present invention will be further described below with reference to the accompanying drawings:

[0029] Example 1:

[0030] like Figures 1-5 The lens cleaning device shown includes a lens 1 and a cleaning device 2 mounted on the lens 1. The cleaning device 2 consists of a main body 3 and a top cover 4 mounted on the main body 3. A sealed air chamber 5 is formed between the main body 3 and the top cover 4. An air inlet 31 is provided on the main body 3 at one end of the air chamber 5. Multiple air outlets 32 are provided inside the cleaning device 2 facing the lens 1. The air inlet 31, the air chamber 5, and the air outlets 32 are connected. A downwardly inclined baffle 6 is provided on the top cover 4. An edge 21 is provided inside the cleaning device 2 facing the lens 1. An air duct 7 is formed between the baffle 6 and the edge 21. The air duct 7 forms a certain angle with the surface of the lens 1. Preferably, in order to adapt to multiple scenarios, the air inlet can be a straight pipe connector or an L-shaped connector.

[0031] The cleaning device 2 is integrally connected to the lens 1. The main body 3 surrounds the lens 360°. The air chamber 5 is a spiral channel. The lower part of the top cover 4 is provided with an inner wall 41. The air outlet 32 ​​is located on the inner wall 41 of the top cover. After the top cover 4 and the main body 3 are sealed together, an air chamber 5 is formed. In order to greatly increase the pressure of the blown air, the front section of the air chamber is wide and the rear section is narrow. A sealing strip 8 is provided between the bottom edge of the inner wall 41 of the top cover and the lens 1 for sealing. The sealing strip 8 extends obliquely to form an edge 21 and covers the edge of the lens 1. The sealing strip 8 is provided with a groove 81 for securing the edge of the lens 1. This not only ensures the stability of the lens, but also ensures that dust will not enter the narrow gap of the lens under the action of high pressure air. The air inlet 31 is located at the front of the main body 3.

[0032] In this embodiment, the air outlet 32 ​​is only provided on one side of the inner wall 41 of the top cover, and the inner wall of the top cover on the other side corresponding to the air outlet is solid.

[0033] In this embodiment, the top cover 4 is connected to the main body 3 by welding to ensure the overall airtightness.

[0034] The working process of this embodiment: In this embodiment, the cleaning device 2 adopts an integrated installation structure, which does not require the replacement of other parts. When dust removal is required, clean high-pressure airflow is blown out through the air inlet 31 through the air chamber 5 and the air outlet 32. The air chamber 5 adopts a spiral channel structure with a wide front and narrow back transition, which can greatly improve the air pressure at the air outlet 32. The edge 21 and the baffle plate 6 form an air duct 7. The airflow blown out of the air duct 7 forms a certain angle with the surface of the lens 1. During the high-speed movement of the airflow, it carries dust and other debris from the surface of the lens 1. The air outlet 32 ​​is only distributed inside the top cover. One side of the wall 41 is a solid wall, which can limit the diffusion of airflow and create a pressure difference on the lens surface. This causes the airflow to swirl and rise within a limited space. Then, under the obstruction on the other side, dust and other debris are moved upward, thus ensuring the cleanliness of the lens 1 surface and preventing secondary pollution. The bottom of the inner wall 41 of the top cover is provided with a sealing strip 8, which firmly seals the lens 1 around. The L-shaped slot 81 seals the lens 1 around and effectively ensures the stability of the lens 1. The top cover 4 and the main body 3 are welded together in an integrated sealing manner to ensure the overall airtightness.

[0035] Example 2:

[0036] like Figures 6-9 The cleaning device 2 shown can also adopt an external structure. The cleaning device 2 is installed on the lens 1 by an external clamp 9. The external clamp 9 includes a clamp ring 91, a bracket 92, and a screw 93 for tightening the clamp ring 91. The main body 3 of the cleaning device 2 is a semi-circular structure. A semi-circular air cavity is formed between the main body and the top cover. The short range and small space can quickly concentrate the airflow to form a high-pressure airflow. The air outlet 32 ​​is set on the inner wall 33 of the main body 3 facing the lens 1. The edge 21 is located at the bottom edge of the main body 3. The air inlet 31 is located at the bottom of the main body 3. In this embodiment, the main body 3 is a semi-circular structure with one end sealed and the other end has an air inlet at the bottom.

[0037] In this embodiment, the cleaning device 2 is suspended on one side of the lens 1 by an external clamp 9.

[0038] In this embodiment, the main body 3 has fixing holes 34 at both ends corresponding to the bracket 92. The cleaning device 2 can be firmly fixed to the external clamp 9 through the fixing holes 34. The cleaning device 2 is provided with fixing holes 34 and can be installed on the bracket on the external clamp 9 with screws. The hoop 91 on the external clamp 9 is firmly fixed to the lens 1 by tightening screws, and it is convenient to replace parts when encountering different application scenarios or structures.

[0039] In the embodiment, the air sweeping device is hung on one side of the lens 1 through the external hanging hoop 9, the top cover 4 is provided with a downward inclined wind deflector 6 at the inner edge of the upper part, the main body 3 is extended with an edge 21 at the inner edge of the bottom part to form an air duct 7 with the wind deflector 6, the air duct 7 forms a certain angle with the surface of the lens 1, and the high-pressure airflow can better take away the dust, sundries or dirt on the surface of the lens 1.

[0040] The air inlet 31 can adopt a straight pipe joint or an L-shaped joint to be conveniently applied in different scenes.

[0041] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
