[0045] It should be noted that: unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] like Figure 1-4 As shown, this embodiment provides a protective device suitable for a camera lens, including a barrel 1 and a flow guide cover 2 , wherein the flow guide cover 2 is mounted on the barrel 1 .

[0047] In some embodiments, the cross-sectional shape of the barrel 1 is adapted to the shape of the camera lens, for example, it can be set to a common circle or rectangle, or to other polygons.

[0048] In some embodiments, the structure of the camera lens can be referred to in the prior art and will not be described in detail here.

[0049] In some embodiments, one end of the barrel 1 is a connecting end, which is used to be sealed and connected to the camera lens; wherein, the connecting end can be directly connected and set on the camera lens, such as by adhesive connection; in addition, the connecting end can also be set on a transparent plate, and then the installation application is realized through the connection between the transparent plate and the camera lens.

[0050] The other end of the barrel 1 is extended along its axial direction, and the extended end of the barrel 1 has an opening. When installed, the barrel 1 is configured to facilitate the camera lens to capture the preset target through the inside of the barrel 1. For example, when used in a telephoto lens, the barrel 1 can be set to a cylindrical shape with a uniform diameter and width, so as to be parallel to the light captured by the camera lens; when used in a wide-angle lens, the barrel 1 can be set to a trumpet shape based on the light captured by the camera lens.

[0051] In this embodiment, the case of application in a telephoto lens is mainly used as an example for description.

[0052] In some embodiments, the deflector 2 is disposed at the extended end of the cylinder 1; Figure 4As shown, a guide air duct 21 is arranged in the guide cover 2, and the two ends of the guide air duct 21 are respectively arranged as a windward port 22 and an air supply port 23. The direction of the windward port 22 is consistent with the extension direction of the cylinder 1, and is mainly used for communicating with the outside world to facilitate the airflow to enter the guide air duct 21; the air supply port 23 is connected with the interior of the cylinder 1, thereby conveying the airflow into the cylinder 1.

[0053] In some embodiments, the air outlet 23 is oriented perpendicular to the axial direction of the cylinder 1 .

[0054] By setting the barrel 1, when the barrel 1 is directly mounted on the camera lens, the connecting end of the barrel 1 can conveniently shield the surface of the camera lens, thereby preventing the pollution source from directly acting on the camera lens; and the setting of the extended end of the barrel 1, whether or not the barrel 1 is directly mounted on the camera lens, can facilitate the formation of an inner cavity with one end open and the other end sealed in the barrel 1, so that even if particulate molecules such as dust and smoke enter the interior from the extended end of the barrel 1, due to the different internal pressures at the two ends of the barrel 1 and the mutual collision and adhesion of the particulate molecules in the elongated space, the adhesion amount of the particulate molecules on the camera lens can be effectively reduced, achieving a waterproof and dustproof effect, thereby facilitating the extension of the service life of the camera lens and reducing the frequency of cleaning and maintenance.

[0055] By setting the deflector 2, the airflow can be concentrated and output from the air supply port 23 to the inside of the cylinder 1 after entering from the windward port 22, so that a blocking airflow can be formed inside the extended end of the cylinder 1 to block external pollution sources such as dust and smoke, increase the difficulty of pollution sources entering the inside of the cylinder 1, and thus further extend the service life and service life of the camera lens.

[0056] As one application example, the air deflector 2 is installed above the extended end of the cylinder 1. By setting the air deflector 2 above the cylinder 1, the air supply port 23 is set downward, so that the pollution source can be blocked and cleaned more conveniently.

[0057] In some embodiments, Figure 1 , 4 As shown, the flow area of ​​the windward opening 23 is set to be larger than the flow area of ​​the air supply opening 23, so that after the airflow enters from the windward opening 22, it can be output from the air supply opening 23 under a certain pressurization effect, and the blocking effect of blocking the airflow is better at this time.

[0058] In some embodiments, reference may be made to Figure 4 As shown, a curved guide surface 211 is provided at the top of the guide air duct 21 . The curved guide surface 211 can facilitate the guidance of the airflow entering the guide air duct 21 , thereby facilitating the output of the airflow from the air supply port 23 .

[0059] In some embodiments, reference may be made to Figure 4 As shown, a waterproof step 212 is provided at the bottom of the guide air duct 21. The waterproof step 212 can prevent water from being output from the air outlet 23 together with air flow in application environments such as rain, thereby preventing splashing inside the cylinder 1 and affecting the imaging effect; and prevent the air outlet 23 from being occupied by excessive water flow, thereby reducing the effect of the air flow.

[0060] As an example of one application, Figure 1 , 4 As shown, the extended end of the cylinder 1 is inclined, so that the side wall of the cylinder 1 forms an inclined longer section 101 and an inclined shorter section 102; when installed and used, the inclined longer section 101 is located above the inclined shorter section 102, so that the inclined longer section 101 can form a certain shielding effect on the inclined shorter section 102, and can facilitate the shedding of dust and the like at the inclined port.

[0061] In some embodiments, the air guide cover 2 is mounted on the inclined longer section 101, and the direction of the air outlet 23 is staggered with the inclined shorter section 102. For example, in the vertical direction, the position of the air outlet 23 does not overlap with the inclined shorter section 102. Figure 3 , 4 shown.

[0062] By arranging the air supply port 23 and the inclined shorter section 102 in a staggered manner, when the air supply port 23 forms an airflow blockage, the airflow can block the pollution source outside the cylinder 1.

[0063] As an example of one application, Figure 1-4 As shown, a plurality of imaging holes 3 are provided inside the barrel 1 , and the imaging holes 3 are also configured so that a camera lens can capture a preset target through the inside of the imaging holes 3 .

[0064] In some embodiments, one end of the imaging channel 3 facing the camera lens is sealed, and the other end of the imaging channel 3 is extended.

[0065] In some embodiments, the plurality of imaging apertures 3 are arranged in the barrel 1 based on the light requirements captured by the camera lens, so as to be suitable for the application of a telephoto lens or a wide-angle lens.

[0066] By setting up the plurality of imaging channels 3, it is convenient to form a honeycomb structure in the barrel 1, thereby extending the effective distance between the extended end of the barrel 1 and the camera lens from which pollution such as particulate molecules originate, and increasing the area available for the attachment of particulate molecules, thereby further improving the protective effect of the camera lens and reducing the frequency of cleaning and maintenance.

[0067] Moreover, by providing the plurality of imaging channels 3, even if some of the imaging channels 3 are blocked, video capture can still be performed based on other unblocked imaging channels 3, thereby achieving better use effect.

[0068] In some embodiments, Figure 4 As shown, the extended ends of the plurality of imaging channels 3 form an inclined end face, and there is a buffer inner barrel section 103 between the inclined end face and the extended end of the barrel 1. The buffer inner barrel section 103 is provided to facilitate the attachment of the pollution source at the extended end of the barrel 1 and facilitate subsequent cleaning operations.

[0069] In some embodiments, a drainage hole 31 is provided on the bottom wall surface of the extended end of the imaging channel 3. The drainage hole 31 can facilitate the discharge of liquid in the imaging channel 3 to improve the waterproof effect of the device.

[0070] In some embodiments, the wall surface of the extended end of the imaging channel 3 is set as a mesh structure surface; by setting the end wall surface of the imaging channel 3 as a mesh structure surface, when rainwater and the like enter the extended end of the imaging channel 3, it will be directly guided, evacuated and discharged through the mesh structure surface, which can further improve the waterproof effect of the device.

[0071] In some embodiments, the mesh structure surface may only serve as the bottom wall surface of the extended end of the imaging channel 3 , and in this case, the mesh holes on the mesh structure surface serve as the drainage holes 31 .

[0072] In some embodiments, the entire circumference of the extended end of the imaging channel 3 may also be set as a mesh structure surface.

[0073] As one application example, along the extension direction of the imaging hole 3, a first imaging hole section 11 and a second imaging hole section 12 are arranged in the barrel 1, a plurality of first imaging holes are arranged in the first imaging hole section 11, and a plurality of second imaging holes are arranged in the second imaging hole section 12; and along the extension direction of the imaging hole 3, a plurality of first imaging holes are arranged in the second imaging hole, such as Figure 1-4 shown.

[0074] In some embodiments, a third imaging aperture segment or more imaging aperture segments may be provided based on actual application requirements.

[0075] In some embodiments, the cross-sectional shape of the imaging channel 3 can be set to be circular or polygonal; and when set to be a polygonal application form, the imaging channels 3 can share a side wall structure, such as Figure 1 , 2 As shown, at this time, the cross-sectional shape of the first imaging hole is a regular hexagon, and the cross-sectional shape of the second imaging hole is a shape surrounded by the outer peripheral walls of the seven first imaging holes.

[0076] By arranging the first imaging channel section 11, the second imaging channel section 12, etc. in the barrel 1, it is convenient to form a segmented protection effect in the barrel 1, thereby gradually increasing the difficulty of pollution sources entering the camera lens.

[0077] As one application example, the protective device further includes a mounting plate 4, and a plurality of fixing holes 41 are provided on the mounting plate 4, so that the mounting plate 4 can be installed on the camera lens by fasteners such as bolts.

[0078] In some embodiments, the mounting plate 4 is a transparent plate, and the barrel 1 and one end of the imaging channel 3 are sealed and connected to the mounting plate 4; a sealing strip 42 is provided on the side of the mounting plate 4 facing away from the barrel 1 corresponding to the camera lens.

[0079] By setting the mounting plate 4, it is possible to facilitate the installation and fixation of the entire protective device on the camera equipment, thereby realizing a matching application solution between the protective device and the camera equipment; and by setting the sealing strip 42, a seal can be formed between the mounting plate 4 and the camera lens to prevent pollution sources from entering and adhering to the camera lens.

[0080] On the other hand, this embodiment also provides a camera device, which includes a camera lens and is provided with the protective device as described above.

[0081] In some embodiments, the camera device can be applied to intelligent visual measurement or scene monitoring.

[0082] By applying the protective device provided in the embodiment to the imaging device, the protective effect of the imaging lens can be improved, thereby extending the service life and life of the imaging lens and reducing the application cost.

[0083] Moreover, the formation of the dust-proof effect at this time will not affect the normal use of the camera lens, and the use effect is better.

For those skilled in the art, the present application may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
