In this embodiment, the automatic dust removing apparatus further includes a third magnetic member 143, the magnetic pole polarity of the third magnetic member 143 is the same as the magnetic pole polarity of the first magnetic member 141, and the third magnetic member 143 is disposed on the rotation track of the first magnetic member 141 and is located at a position close to the outdoor camera lens 221.
In the present embodiment, the third magnetic member 143 employs a magnet. It will be understood that the third magnetic member 143 may be configured as an electromagnet or other element or structure. When the blade 12 stops rotating quickly, the blade 12 is far away from the lens 221 of the outdoor camera, so that the blade 12 is prevented from staying at the lens 221 to shield the lens 221, and the shooting of the outdoor camera is affected.
The automatic dust removing device for an outdoor camera according to this embodiment is provided with the third magnetic member 143, and drives the blade 12 away from the outdoor camera lens 221 when the rotation speed of the blade 12 is reduced by using the principle of homopolar repulsion, so as to prevent the blade 12 from shielding the lens 221 and interfering with camera shooting.
In a preferred embodiment, the third magnetic member 143 includes a plurality of sub-magnetic members disposed on the rotation track of the first magnetic member 141 at intervals.
By providing a plurality of sub-magnetic members, the plurality of sub-magnetic members are arranged at intervals at positions close to the outdoor camera lens 221, so that the blade 12 can be driven to be far away from the outdoor camera lens 221 better, and the blade is prevented from shielding the lens 221.
Another aspect of this embodiment provides an outdoor camera, which includes an automatic dust removing device for an outdoor camera according to any one of the above.
The outdoor camera of this embodiment example can solve the dirty problem of camera lens 221 effectively through setting up automatic dust collector, and simple structure, hardware cost are low simultaneously, and most operating time is passive dust removal, and whole energy is low, and the inside and outside no continuous mechanism of equipment, can not influence the gas tightness of complete machine.
In this embodiment, the outdoor camera further includes a main body 21 and an image capturing device 22, the image capturing device 22 is disposed on the main body 21, and the image capturing device 22 includes a lens 221; the automatic dust removing device is arranged at a position close to the lens 221, the length of the wiper 13 in the automatic dust removing device is not smaller than the diameter of the lens 221, the area 300 where the blades rotate in the automatic dust removing device can cover the area where the lens 221 is located, and the second magnetic piece 142 in the automatic dust removing device is arranged inside the main body 21 and is located outside the lens 221.
The length of the wiper 13 is set to be not smaller than the diameter of the lens 221, and the relative positions of the blades 12 and the lens 221 are set so that the area 300 swept by the wiper can cover the area where the lens 221 is located, thus the lens 221 can be comprehensively cleaned by the automatic dust removal device, and the dust removal effect is ensured.
Meanwhile, the second magnetic member 142 is disposed outside the lens 221, so that the situation that the blade 12 stays at the window of the lens 221 when stopping rotation, and the photographing of the lens 221 is disturbed can be effectively avoided.
In order to facilitate understanding of the embodiments of the present invention, the following describes a dust removal method of the outdoor camera provided with the automatic dust removal device:
fig. 3 is a schematic view illustrating a use state of the automatic dust removing device in the present embodiment for removing dust from an outdoor camera lens.
When the outdoor camera is in standby, the second magnetic element 142, i.e. the electromagnet, arranged inside the outdoor camera is powered off. At this time, when the outside has wind, the blade 12 rotates freely under the effect of the wind force, and drives the wiper 13 on the blade 12 to sweep the lens 221 window of the image acquisition device 22, so that the lens 221 window can keep clean under the continuous scraping of the brush.
Under windy conditions, when the camera needs to shoot or shoot videos, the second magnetic part 142 electromagnet arranged inside the camera is electrified due to the startup of the camera, and at the moment, when any group of blades 12 rotate to a position close to the electromagnet, the blades 12 are attracted by the electromagnet, namely, the blades 12 are fixed, so that the blades 12 do not rotate any more, and the situation that the blades 12 rotate to interfere with shooting of the lens 221 is effectively avoided. After shooting is finished, the electromagnet is powered off, and the blade 12 continues to rotate.
Under the condition that wind power is reduced to breeze or no wind, the rotating speed of the blade 12 is gradually reduced, when the blade slowly rotates to the area of the camera lens 221, an acting force with like magnetic poles and mutual exclusion is generated between the third magnetic piece 143 and the first magnetic piece 141, when the acting force is larger than the rotating force of the blade 12, the blade 12 can be driven to be far away from the outdoor camera lens 221 and stop at the area outside the window of the lens 221, and therefore the situation that the blade 12 stays in front of the window of the lens 221 due to the fact that the blade 12 cannot be locked due to no rotation of the blade 12, the locking component cannot be locked is avoided.
