Description

Technical Field

[0001] This utility model relates to the field of dust prevention, and in particular to a dust prevention device and a shooting component. Background Technology

[0002] After a period of operation in outdoor environments, dust will accumulate on the lens of a camera, leading to a decrease in image quality. Therefore, most cameras used outdoors require regular lens cleaning.

[0003] The current mainstream lens cleaning method is as follows: the camera is equipped with a water tank and a squeegee. The water tank sprays cleaning water onto the lens, and then the squeegee, driven by a motor, scrapes and cleans the lens. Because it needs to be cleaned many times and frequently, on the one hand, the water tank needs to be manually replenished frequently, and more importantly, the energy consumption of the water tank during the water spraying process and the energy consumption of the motor driving the squeegee are both considerable. Utility Model Content

[0004] Therefore, it is necessary to provide a dustproof device and shooting components to address the issue of high power consumption of cameras during the cleaning process.

[0005] A dustproof device includes a housing and a baffle.

[0006] The housing is provided with an air guide cavity, and the housing sidewall is provided with an air inlet and an air outlet, which are connected to the air guide cavity;

[0007] The baffle is rotatably mounted on the housing to have a blocking state and a yielding state; when the baffle is in the blocking state, the baffle blocks the air inlet; when the baffle is in the yielding state, the baffle is at least partially located in the air guide cavity to yield to the air inlet.

[0008] In one embodiment, the baffle is rotatably disposed on the housing about a first axis located above or at the top edge of the air inlet, so as to allow the baffle to be in a blocking state under the action of gravity.

[0009] In one embodiment, the dustproof device further includes a filter screen installed in the air guide cavity, the filter screen being located between the air inlet and the air outlet.

[0010] In one embodiment, the number of air inlets is at least two.

[0011] In one embodiment, when the baffle is in a blocking state, the baffle abuts against the inner wall of the air guide cavity.

[0012] In one embodiment, there is only one air outlet.

[0013] A shooting assembly includes a shooting device and a dustproof device. The shooting device has a shooting window, and the housing is mounted on the shooting device to allow air blown from the air outlet to blow toward the shooting window or form an air curtain in front of the shooting window.

[0014] In one embodiment, the edge of the air outlet is extended to form a wind deflector, which is used to limit the airflow from the air outlet from flowing away from the shooting window.

[0015] In one embodiment, the windshield is provided with a clearance opening, and the shooting window is located at the clearance opening.

[0016] In one embodiment, a dustproof plate is provided on the outer wall of the housing, and the dustproof plate is located above the shooting window.

[0017] The beneficial effects of this utility model are as follows:

[0018] Firstly, when the air inlet is in a windless state, the baffle is in a blocking state, which can prevent dust from entering the air guide cavity through the air inlet.

[0019] Secondly, when there is wind at the air inlet, the wind will blow the baffle, causing the baffle to rotate inside the air guide cavity and turn into a deflector state. In this way, the air inlet can collect wind that would not normally flow directly to the shooting window, and then change the direction of this wind through the air guide cavity and air outlet, directing it towards the shooting window or forming an air curtain in front of the shooting window, thereby achieving a dust-proof effect. This dust-proof method effectively utilizes ambient wind energy to clean the shooting window, reducing or eliminating the use of electricity and greatly reducing power consumption during the cleaning process.

[0037] Example 1:

[0038] like Figure 1 As shown, this embodiment provides a shooting assembly, including a shooting device 4 and a dustproof device. A shooting window 41 is provided on the front side wall of the shooting device 4, and the dustproof device is installed on the shooting device 4 to protect the shooting window 41 from dust.

[0039] Specifically, such as Figures 4-9As shown, the dustproof device includes a housing 1 and a baffle 2. An air guide cavity 11 is provided inside the housing 1, and an air inlet 12 and an air outlet 13 are also provided on the side wall of the housing 1. Both the air inlet 12 and the air outlet 13 are connected to the air guide cavity 11, so the air inlet 12 can be connected to the air outlet 13 through the air guide cavity 11.

[0040] The baffle 2 is rotatably mounted on the housing 1 around the first axis, so as to have a blocking state and a avoidance state.

[0041] like Figure 2 As shown, when the air inlet 12 is in a windless state, the baffle 2 is in a blocking state. At this time, the baffle 2 blocks the air inlet 12 to prevent dust from drifting into the air guide cavity 11 through the air inlet 12.

[0042] When there is wind at the air inlet 12, the wind at the air inlet 12 will blow the baffle 2, causing the baffle 2 to rotate inside the guide cavity 11 and turn into an avoidance state. Figure 3 As shown, when the baffle 2 is in the avoidance state, the baffle 2 is at least partially located in the air guide cavity 11, thereby avoiding the air inlet 12. As a result, the air at the air inlet 12 can enter the air guide cavity 11 and then flow to the air outlet 13 under the guidance of the air guide cavity 11, thereby causing the air outlet 13 to blow air.

[0043] In some other embodiments, the air blown out from the air outlet 13 can be blown directly toward the shooting window 41, thereby cleaning the shooting window 41 or making it difficult for dust to approach the shooting window 41, thus achieving a dust prevention effect.

[0044] In this embodiment, such as Figure 6 As shown, the air blown out from the air outlet 13 can form an air curtain in front of the shooting window 41, thereby blocking dust.

[0045] In other words, the technical concept of the dustproof device in this embodiment is as follows: Air that does not normally flow directly to the shooting window 41 is collected through the air inlet 12, and then the airflow direction is changed through the air guide cavity 11 and the air outlet 13, so that it can blow towards the shooting window 41 or form an air curtain in front of the shooting window 41, thereby achieving a dustproof effect on the shooting window 41. This dustproof method effectively utilizes the wind energy in the environment to clean the shooting window 41, reducing or avoiding the use of electrical energy and greatly reducing the power consumption of the shooting window 41 during the cleaning process.

[0046] It is worth noting that the shooting window 41 is most prone to dust accumulation when the wind blows around the shooting device 4, causing dust to fly. However, the dustproof device of this embodiment can simultaneously utilize the wind that causes dust to fly at that moment to achieve a dustproof effect. In other words, the dustproof device of this embodiment can achieve a dustproof effect when the shooting window 41 most needs dust protection.

[0047] It is understandable that if dusty air enters the air guide cavity 11 and goes directly to the air outlet 13, it will reduce the dustproof effect on the shooting window 41. To solve this problem, the dustproof device in this embodiment also includes a filter 3, which is installed in the air guide cavity 11 and located between the air inlet 12 and the air outlet 13.

[0048] Preferably, there are at least two air inlets 12. Increasing the number of air inlets 12 allows the dustproof device to collect air from more different directions for dust prevention at the shooting window 41, thus improving the dust prevention effect at the shooting window 41. At the same time, there is only one air outlet 13, which can concentrate the air intake from all the air inlets 12 for dust prevention at the shooting window 41. Each air inlet 12 is equipped with a corresponding baffle 2 that rotates.

[0049] like Figure 6 As shown, in this embodiment, the first axis is located above or at the top edge of the air inlet 12. Based on this structure, when the airflow stops at the air inlet 12, the baffle 2 can automatically flip and switch back to the blocking state under the action of gravity without the need for elastic elements such as torsion springs, thus blocking the air inlet 12 again.

[0050] Furthermore, as a preferred embodiment, the size of the baffle 2 is slightly larger than the size of its corresponding air inlet 12. In other words, as... Figure 7 As shown, when the baffle 2 is in the blocking state, the edge of the baffle 2 will abut against the inner wall of the air guide cavity 11. This enhances the blocking and sealing effect of the baffle 2 on the edge of the air inlet 12, and also prevents the baffle 2 from rotating outside the air guide cavity 11. In other words, the air outside the air inlet 12 can enter the air guide cavity 11 by blowing the baffle 2 into the air guide cavity 11, but the air inside the air guide cavity 11 cannot leave the air guide cavity 11 by blowing the baffle 2 outward from the air inlet 12. Based on this, the air inside the air guide cavity 11 can only leave through the air outlet 13 and be used for dust removal. This design greatly reduces the waste of wind energy.

[0051] See details Figure 1 , Figure 5 and Figure 6 In this embodiment, the edge of the air outlet 13 extends to form a baffle 131, which is generally parallel to the shooting window 41. The air blowing from the air outlet 13 is restricted by the baffle 131, making it difficult or impossible for it to flow away from the shooting window 41. Therefore, the air blowing from the air outlet 13 is effectively confined between the baffle 131 and the outer wall of the shooting device 4, thus forming an air curtain in front of the shooting window 41. This allows the air blowing from the air outlet 13 to be fully utilized for dust prevention of the shooting window 41, reducing the waste of wind energy.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, the wind deflector 131 is provided with an avoidance opening 132, and the shooting window 41 is located at the avoidance opening 132. The wind deflector 131 reduces interference with the shooting action of the shooting window 41 through the avoidance opening 132.

[0053] Preferably, in this embodiment, a dustproof plate 14 is provided on the outer wall of the housing 1. The dustproof plate 14 is located above the shooting window 41. The dustproof plate 14 can reduce the occurrence of dust falling onto the shooting window 41 in the absence of wind.

[0054] 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.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, 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.
