Insect-proof camera

Abstract

The application relates to an anti-insect camera, which comprises a camera assembly and an insect expelling module. The camera assembly has a window for light transmission. The insect expelling module comprises a fan blade located in front of the window and a driving member fixedly connected to the camera assembly. The driving member is drivingly connected to the fan blade. The rotation surface of the fan blade under the driving of the driving member is located in front of the window. The rotation of the fan blade directly drives away the mosquitoes located in front of the window of the camera assembly. Compared with the wind power insect expelling, the anti-insect camera reduces the design of the air duct, and the production, assembly, packaging and transportation costs are lower. Since the air tightness of the camera assembly is not changed, the electronic elements in the camera assembly are also protected.

Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to an insect-proof camera. Background Technology

[0002] Existing cameras, installed outdoors in dark, damp places, or in large numbers, are often exposed to mosquitoes and spider webs at night. These cameras haven't adequately addressed mosquito and spider web prevention. Since cameras need to use white or infrared lights for nighttime recording, mosquitoes are attracted to these lights. After a period of use, the camera's viewfinder will likely accumulate dead mosquitoes or spider webs, resulting in unclear images and significantly impacting the user experience.

[0003] One existing insect-repelling camera uses a built-in axial fan. When mosquitoes are detected, the axial fan turns on, using airflow to drive them away. This airflow-based insect-repelling solution requires adjustments to the camera's internal structure, particularly the design of air ducts inside the camera, which significantly increases the size of the device and raises costs for the device itself, its packaging, and transportation. Utility Model Content

[0004] Existing wind-powered insect repellent solutions based on cameras tend to lead to complex camera structures and increased production costs. Therefore, it is necessary to provide an insect-repellent camera.

[0005] This application provides an insect-proof camera, including:

[0006] A camera assembly, the front cover of which has a window for light transmission; and,

[0007] The insect repellent module includes a fan blade located in front of the window and a drive unit fixed to the camera assembly. The drive unit is driven to the fan blade, and the rotating surface of the fan blade under the drive of the drive unit is located in front of the window.

[0008] With this configuration, the present application places fan blades in front of the window, with the rotating surface of the fan blades located in front of the window. The rotation of the fan blades directly drives away mosquitoes located at the window of the camera assembly. Compared with wind-powered insect repellent, this reduces the design of the air duct. The drive component only needs to be fixed to the camera assembly, and there is no need to reserve space inside the camera assembly to accommodate the drive component. Therefore, the insect-repelling camera provided by the present application has a lower cost, and the assembly, packaging, and transportation costs are also lower. In addition, since insect repellent scenarios are mostly in humid areas, areas with many trees, livestock farms, and other environments with a lot of moisture and dust in the air, the present application places the insect repellent module outside the camera assembly, which does not change the airtightness of the camera assembly and helps protect the internal electronic components of the camera assembly.

[0009] In one embodiment, the drive unit includes a drive shaft and a drive motor fixedly connected to the camera assembly;

[0010] The fan blade includes a connector sleeved on the drive shaft and a blade body extending radially from the connector.

[0011] This configuration, by installing the fan blades in a nested manner, improves the reliability of the connection between the fan blades and the drive components.

[0012] In one embodiment, considering that the camera component has no obvious need for insect repellency in daytime scenarios, the insect repellency module has a non-working state. When the insect repellency module is in the non-working state, the leaf body is located outside the window.

[0013] With this setting, when the insect repellent module is not in operation, the blade itself will not enter the window and will not affect the normal imaging of the insect-repellent camera.

[0014] In one embodiment, considering that the fan blades may block the window in actual use and affect the brightness of the image or even block part of the image, an abutment block is also fixed on the drive shaft. The fan blades also include an abutment extending axially from the connector. The connector is rotatably mounted on the drive shaft. The abutment is used to abut the abutment block circumferentially to drive the fan blades to rotate under the rotation of the drive shaft. The drive shaft (12) is located below or to the side of the camera assembly.

[0015] With this setup, when insect repellency is needed, the abutment block on the drive shaft pushes the abutment body to cause the fan blades to rotate with the drive shaft. When insect repellency is not needed, the drive shaft stops rotating, and the fan blades continue to rotate around the drive shaft due to inertia. The abutment body separates from the abutment block. Furthermore, under the influence of gravity, the fan blades will eventually stop at a position extending vertically downwards. Since the drive shaft is located below or to the side of the camera assembly, the fan blades are offset from the window when not in operation, avoiding interference with the camera assembly's image.

[0016] In one embodiment, the number of fan blades is multiple, and the number of abutment blocks is the same as the number of fan blades;

[0017] The plurality of fan blades are stacked at intervals along the axial direction of the drive shaft;

[0018] The plurality of abutment blocks are arranged sequentially at intervals along the circumference of the drive shaft.

[0019] With this configuration, multiple fan blades are stacked at intervals on the axis, causing the influence space formed by the rotation of multiple fan blades to change periodically along the axis. In other words, the rotation of multiple fan blades forms a spiral space, which makes the airflow disturbance at the window of the camera component more intense, which is beneficial to improving the insect repellent effect.

[0020] In one embodiment, a plurality of the abutment blocks are evenly distributed circumferentially on the drive shaft.

[0021] This configuration helps to balance the rotation center of the drive shaft, preventing the shaking caused by rotation from being transmitted to the camera components and causing the monitoring image to jitter.

[0022] In one embodiment, the connecting body of the fan blade is further provided with an assembly hole for the abutment block to pass through.

[0023] This design makes it easier to fit the fan blades onto the drive shaft one by one through the mounting holes, reducing assembly difficulty.

[0024] In one embodiment, the abutment block or the connector is an elastic component and the size of the mounting hole is smaller than the radial cross-sectional size of the abutment block.

[0025] With this configuration, the fan blades will not easily detach from the drive shaft after being installed.

[0026] In one embodiment, in order to minimize the obstruction of the camera assembly window by the fan blades, the drive shaft is located below the camera assembly.

[0027] In one embodiment, the camera component includes:

[0028] The camera body has a viewing window and a fill light port;

[0029] A viewing window glass, covering the viewing window;

[0030] A supplementary light glass cover is provided on the supplementary light opening;

[0031] The device plate is fixed to the front cover of the camera body and has a first window that matches the shape of the viewing window glass and a second window that matches the shape of the fill light glass;

[0032] The decorative panel, the viewing window glass, and the fill light glass are flush with the outward-facing side.

[0033] With this setup, the window of the camera component is flat and without grooves, avoiding providing a foothold for spider webs or mosquitoes to climb and attach to.

[0034] In one embodiment, the decorative panel has an outward-facing polished surface with a gloss level GU ≥ 90 and a surface roughness Ra less than or equal to 0.05 μm.

[0035] With this design, the polished surface of the decorative panel is ultra-high gloss, which is smoother than ordinary plastic. This further reduces the risk of cobweb adhesion, effectively prevents insects, reduces screen obstruction, increases light intake, and improves image quality. Attached Figure Description

[0052] Existing cameras, installed outdoors in dark, damp places, or in large numbers, are often exposed to mosquitoes and spider webs at night. These cameras haven't adequately addressed mosquito and spider web prevention. Since cameras need to use white or infrared lights for nighttime recording, mosquitoes are attracted to these lights. After a period of use, the camera's viewfinder will likely accumulate dead mosquitoes or spider webs, resulting in unclear images and significantly impacting the user experience.

[0053] One existing insect-repelling camera uses a built-in axial fan. When mosquitoes are detected, the axial fan turns on, using airflow to drive them away. This airflow-based insect-repelling solution requires adjustments to the camera's internal structure, particularly the design of air ducts inside the camera, which significantly increases the size of the device and raises costs for the device itself, its packaging, and transportation.

[0054] Therefore, it is necessary to provide a low-cost insect-proof camera with good insect-proof effect.

[0055] Please see Figure 1 In one embodiment provided in this application, the insect-repelling camera includes a camera assembly and an insect-repelling module 2. The front cover 8 of the camera assembly has a window for light transmission. The insect-repelling module 2 includes a fan blade 7 and a drive member 6. The fan blade 7 is located in front of the window, and the drive member 6 is fixedly connected to the camera assembly. The drive member 6 is driven by the fan blade 7, and the rotating surface of the fan blade 7 under the drive of the drive member is located in front of the window, thereby repelling mosquitoes located at the window. The technical solution of this application eliminates the need to add an air duct structure inside the camera assembly. By placing the insect-repelling module 2 externally, the structure of the camera assembly is simplified. Since the air duct is eliminated, the internal and external spaces of the camera assembly are isolated. Considering that insect-repelling scenarios are mostly in humid areas, areas with many trees, and livestock farms, where there is a lot of water vapor and dust in the air, this also helps to protect the electronic components inside the camera assembly.

[0056] Specifically, in one embodiment provided in this application, the driving component 6 includes a driving shaft 12 and a driving motor fixedly connected to the camera assembly; the fan blade 7 includes a connecting body 10 sleeved on the driving shaft 12 and a blade body 9 extending radially from the connecting body 10. This sleeved arrangement improves the reliability of the connection between the fan blade 7 and the driving shaft 12; furthermore, the rotating surface of the blade body 9 is close to the window, resulting in a better insect-repelling effect. Additionally, for a typical surveillance camera, the blade body 9 is within the focal length of the camera and will not obstruct the actual image.

[0057] Optionally, in one embodiment provided in this application, the insect repellent module 2 has a non-working state. When the insect repellent module 2 is in a non-working state, the blade body 9 is located outside the window. Preferably, in one embodiment provided in this application, the insect repellent module 2 is communicatively connected to the camera component. In actual insect repelling scenarios (mostly at night, and the supplementary light of the camera component is on), when the camera component detects the density of mosquitoes or the number of spider webs within the window range, the drive component 6 is activated. The drive component 6 drives the fan blade 7 to rotate to achieve the insect repelling function. When the density of mosquitoes or the number of spider webs is lower than a certain value, the drive component 6 is turned off, the fan blade 7 stops rotating, and the blade body 9 is located outside the window, without affecting the imaging function of the camera component. It is understood that the insect repellent module 2 can be an optional structure, that is, adapted to be installed on existing camera components. The insect repellent module 2 and the camera component can be communicatively connected via a tail cable or a USB cable.

[0058] Please see Figures 1 to 4 In one embodiment provided in this application, the camera assembly includes a camera body 1, a viewing window 3, a fill light glass 4, and a decorative panel 5. The camera body 1 has a viewing window and a fill light port. The viewing window 3 and the fill light glass 4 are respectively covered on the viewing window and the fill light port. The decorative panel 5 is fixed to the front cover 8 of the camera body 1. Moreover, the decorative cover also has a first window that matches the shape of the viewing window 3 and a second window that matches the shape of the fill light glass 4. It is worth noting that in this embodiment, the decorative panel 5, the viewing window 3, and the fill light glass 4 are flush on the outward side. In this way, the window of the camera assembly is flat and without grooves, avoiding providing a support point for spider webs or mosquitoes to climb and attach, and reducing the possibility of mosquitoes attaching to the decorative panel 5 or the viewing window. Optionally, in one embodiment provided in this application, the decorative panel 5 has an outward polished surface with a gloss level GU greater than or equal to 90 and a surface roughness Ra less than or equal to 0.05 μm. In this way, the polished surface is an ultra-high gloss surface, which is smoother than ordinary plastic surfaces, further reducing the risk of cobweb adhesion, effectively preventing insects, reducing obstruction at windows, increasing light intake, and improving image quality.

[0059] Please see Figure 6 , Figure 7 and Figure 8 Optionally, in one embodiment provided in this application, a stop block 13 is also fixed on the drive shaft 12, and the fan blade 7 further includes a stop body 11 extending axially from the connector 10. The connector 10 is rotatably mounted on the drive shaft 12, and the stop body 11 is used to abut against the stop block 13 in the circumferential direction so that the fan blade 7 can rotate under the rotation of the drive shaft 12. The drive shaft 12 is located below the camera assembly. Based on this structural scheme, when insect repellency is required, the stop block 13 on the drive shaft 12 pushes the stop body 11 to drive the fan blade 7 to rotate together with the drive shaft 12. When insect repellency is not required, the drive shaft 12 stops rotating, and the fan blade 7 will continue to rotate around the drive shaft 12 under the action of inertia. The stop body 11 separates from the stop block 13. Furthermore, under the action of gravity, the fan blade 7 will eventually stop at a position extending vertically downward, that is, it will deviate from the window and avoid interfering with the image of the camera assembly. It is understandable that when the insect repellent module 2 switches from the working state to the non-working state, the abutment block 13 can be positioned downwards by controlling the rotation angle of the drive shaft 12. When the fan blade 7 continues to rotate one revolution under inertia, it will be stopped by the abutment block 13. It is worth noting that, based on this control method, the abutment block 13 has a pushing surface and a stopping surface arranged opposite to each other. The pushing surface is used to push the fan blade 7 to rotate under the rotation of the drive shaft 12, and the stopping surface is used to prevent the fan blade 7 from rotating further under inertia when the drive shaft 12 stops rotating. Furthermore, when the insect repellent module 2 is in the non-working state, in order to ensure that the fan blade 7 is not within the window range, the stopping surface is positioned downwards. It is understandable that, in other embodiments, the drive shaft 12 can also be located to the side of the camera assembly, as long as the fan blade is outside the window in the non-working state.

[0060] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, there are multiple fan blades 7, and the number of abutment blocks 13 is the same as the number of fan blades 7. The multiple fan blades 7 are stacked at intervals along the axial direction of the drive shaft 12, and the multiple abutment blocks 13 are arranged at intervals along the circumference of the drive shaft 12. On the one hand, the multiple fan blades 7 are stacked at intervals on the shaft, so that the influence space formed by the rotation of the multiple fan blades 7 exhibits a periodic change in the axial direction. That is, the multiple fan blades 7 rotate to form a spiral space, which makes the airflow disturbance at the window of the camera component more intense, which is conducive to improving the insect repelling effect. On the other hand, this application realizes the switching between the working state and the non-working state of the insect repelling module 2 by the abutment block 13 on the drive shaft 12 and the abutment body 11 on the fan blade 7. In addition, the arrangement of the drive shaft 12 relative to the camera component ensures that the multiple fan blades 7 are offset from the window of the camera component in the non-working state, avoiding interference with the normal imaging of the camera component and ensuring the insect repelling efficiency. For example, in one embodiment provided in this application, there are three abutment blocks 13 and three fan blades 7, and the angular interval between two adjacent abutment blocks 13 arranged circumferentially along the drive shaft 12 is 120°. It is worth noting that... Figure 1 , Figure 3 and Figure 4 In order to show the number and positional relationship of the fan blades 7, multiple fan blades 7 are placed in a staggered manner. In fact, when the insect repellent module 2 is not in working state, multiple fan blades 7 are stacked in the axial direction of the drive shaft 12.

[0061] Furthermore, such as Figure 7 As shown, multiple abutment blocks 13 are evenly distributed circumferentially on the side of the drive shaft 12. This helps to balance the rotation center of the drive shaft 12 and prevents the rotation center of the multiple fan blades 7 from deviating from the rotation axis of the drive shaft 12, which would cause the insect repellent module 2 to shake during operation. This helps to improve the stability of the monitoring screen.

[0062] Optionally, in another embodiment of this application, the axial projections of the multiple abutment blocks 13 overlap, that is, the multiple abutment blocks 13 are arranged linearly along the axial direction on the drive shaft 12, and the blade bodies 9 and connecting bodies 10 of the multiple fan blades 7 are arranged sequentially along the axial direction. The positions of the abutment bodies 11 of each fan blade 7 on the connecting body 10 are different. Taking the insect repellent module 2 in a non-working state as an example, two adjacent abutment bodies 11 are arranged sequentially at intervals along the circumference of the drive shaft 12. It can be understood that in the non-working state, the abutment bodies 11 of the multiple fan blades 7 are evenly distributed along the circumference of the drive shaft 12. Taking three fan blades 7 as an example, the angular interval of the circumferential arrangement of the abutment bodies 11 of two adjacent fan blades 7 is 120°.

[0063] It is understood that in other embodiments, the positions of the abutment block 13 and the abutment body 11 can be arranged sequentially around the axis of the drive shaft 12, as long as it can be ensured that the insect repellent module 2 will not block the window of the camera component when it is not in operation.

[0064] like Figure 8 As shown, optionally, for ease of assembly, the connecting body 10 of the fan blade 7 is also provided with an assembly hole 14 for the abutment block 13 to pass through.

[0065] Optionally, in order to ensure installation and prevent the fan blade 7 from slipping off the drive shaft 12, in one embodiment provided in this application, the abutment block 13 or the connector 10 is an elastic component and the size of the mounting hole 14 is smaller than the radial cross-sectional size of the abutment block 13.

[0066] like Figure 8 As shown, in order to avoid the fan blades 7 from obstructing the camera assembly window as much as possible, the drive shaft 12 is located below the camera assembly.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
