[0027] 1.

With the increase of the airflow volume inside the diverter box and the combined effect of centrifugal force, the airflow is finally sprayed toward the camera lens through the cleaning port. Since the fins are arranged at an angle, the airflow sprayed out through the cleaning port will quickly flow away from the security camera after passing through the camera lens, and carry the dust and moisture adsorbed on the surface of the camera lens, thereby being able to dry and clean the camera lens without interfering with the camera lens, thereby ensuring the integrity of the security monitoring video.

[0028] 2. In the present invention, the airflow can cool down the interior of the security camera during the unidirectional circulation flow in the special-shaped tube, and heat the airflow at the same time. The heated airflow acts on the surface of the camera lens, which can dry the camera lens and prevent the camera lens surface from being affected by water mist due to the relatively humid working environment, which affects the picture clarity.

[0029] 3. In the present invention, during the operation of the security camera, in addition to being transmitted toward the camera lens, the electrical signal is also filtered by a low-pass filter to obtain a low-frequency signal. The low-frequency signal is transmitted toward the blower assembly, converted by a driving source to obtain bass, and the high amplitude characteristics of the bass are used to drive the first eardrum and the second eardrum to move back and forth in the vertical direction. On the one hand, since the blower assembly has no other driving medium except the bass, the blower assembly does not generate any other noise except the bass, and the bass is integrated into the recorder to improve the sound quality of the security camera monitoring screen, and make the monitoring video sound fuller and more three-dimensional. On the other hand, there are no other electronic components except the low-pass filter, and the low-pass filter is used to filter the frequency of the electrical signal, and will not generate a magnetic field that interferes with the electrical signal. Therefore, the entire cleaning system will not generate a magnetic field that interferes with the electrical signal. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The specific implementation method is as follows: when the first eardrum 5032 bulges upward, the second eardrum 5042 also bulges upward; when the first eardrum 5032 is sunken downward, the second eardrum 5042 also sunken downward; when the first eardrum 5032 bulges upward, the first one-way valve 6 and the third one-way valve 8 are opened, and the second one-way valve 7 and the fourth one-way valve are closed; the airflow circulating in the unidirectional manner in the special-shaped tube 12 is sucked into the bellows box 501 through the three-phase tube 9, and the air located at the first eardrum 5032 is in the bellows box 501, and the air located at the second eardrum 5042 in the bellows box 501 flows out through the second output pipe 11 into the second input pipe 205, and then flows to the diverter box 201; when the first eardrum 5032 is sunken downward, the second one-way valve 7 and the fourth one-way valve are opened, and the first one-way valve 6 When the first and second one-way valves 8 are closed, the airflow circulating in the special-shaped tube 12 in one direction is sucked into the bellows 501 through the three-phase tube 9 and located at the second eardrum 5042, while the air at the first eardrum 5032 in the bellows 501 flows out through the first output pipe 10 into the first input pipe 204, and then flows to the diverter box 201. During the airflow flowing in the first input pipe 204, the first valve plate 302 is pushed to rotate around the first flip axis 303, and the first adapter spring 304 is twisted to cause it to undergo elastic deformation. Since the airflow entering the diverter box 201 is along the radial direction, it will directly and reversely act on the blade 203 array, thereby driving the fin 206 array on the inner ring surface of the rotating ring 202 to perform circular motion in the opposite direction.

[0049] Working principle, when using:

[0050] During the operation of the security camera, in addition to being transmitted toward the camera lens 1, the electrical signal is also filtered by the low-pass filter to obtain a low-frequency signal, which is transmitted toward the air blowing assembly 5 and converted by the driving source 502 to obtain bass. The high amplitude characteristics of the bass are used to drive the first eardrum 5032 and the second eardrum 5042 to reciprocate in the vertical direction;

[0051] When the first eardrum 5032 bulges upward, the second eardrum 5042 also bulges upward. When the first eardrum 5032 is sunken downward, the second eardrum 5042 is also sunken downward. When the first eardrum 5032 bulges upward, the first one-way valve 6 and the third one-way valve 8 are opened, and the second one-way valve 7 and the fourth one-way valve are closed. The airflow circulating in the special-shaped tube 12 in one direction is sucked into the blower box 501 through the three-phase tube 9, and the air located at the first eardrum 5032 is in the blower box 501. The air located at the second eardrum 5042 in the blower box 501 flows out through the second output pipe 11 into the second input pipe 205, and then flows to the diverter box 201. The airflow flowing in the second input pipe 205 is During the process, the second valve plate 402 is pushed to rotate around the second flip axis 403, and the second adapter spring 404 is twisted to cause elastic deformation. Since the airflow entering the diverter box 201 is along the radial direction, it will directly act on the blade 203 array, thereby driving the fin 206 array on the inner ring surface of the rotating ring 202 to make a circular motion. With the increase of the airflow volume inside the diverter box 201 and the combined effect of centrifugal force, the airflow is finally sprayed toward the camera lens 1 through the cleaning port 207. Since the fins 206 are arranged at an angle, the airflow sprayed out through the cleaning port 207 will quickly flow away from the security camera after passing through the camera lens 1.

[0052] When the first eardrum 5032 is sunken downward, the second one-way valve 7 and the fourth one-way valve are opened, and the first one-way valve 6 and the third one-way valve 8 are closed. The airflow circulating in the special-shaped tube 12 in one direction is sucked into the bellows box 501 through the three-phase tube 9, and the air located at the second eardrum 5042 is in the bellows box 501. The air at the first eardrum 5032 in the bellows box 501 flows out through the first output pipe 10 into the first input pipe 204, and then flows to the diverter box 201. During the airflow flowing in the first input pipe 204, the first valve plate 302 is pushed to rotate around the first flip axis 303, and the first transfer spring 304 is twisted to make it elastically deformed. The air entering the diverter box 201 Since the flow is along the radial direction, it will directly and reversely act on the blade 203 array, thereby driving the fin 206 array on the inner ring surface of the rotating ring 202 to perform circular motion in the opposite direction. With the increase of the airflow inside the diverter box 201 and the combined effect of centrifugal force, the airflow is finally sprayed toward the camera lens 1 through the cleaning port 207. Since the fins 206 are arranged at an angle, the airflow ejected through the cleaning port 207 will quickly flow toward the security camera after passing through the camera lens 1 and carry the dust and moisture adsorbed on the surface of the camera lens 1. At the same time, it can also clean the dust on the end face of the security camera. The airflow acts on the camera lens 1 along multiple flow directions.
