[0024] The automatic cleaning monitoring camera provided by the utility model discriminates whether there is any attachment on the front windshield by the identification device, and sends a cleaning start signal to the control device when there is an attachment, to activate the air outlet to be disposed on the front windshield. The upper edge of the blowing device allows the blowing device to convey airflow to the front glass, and the attachment on the front windshield is blown off, which is convenient to clean and can improve the quality of the monitoring picture.

1 is a schematic structural view of an automatic cleaning monitoring camera provided by the present invention, the camera includes: a camera body 1, a front windshield 5 is disposed in front of a lens of the camera body 1; an identification device 4, the identification device 4 is mounted on the edge of the windshield 5 for determining whether there is any attachment on the windshield 5, and when the front windshield 5 has an attached object, sending a cleaning start signal to the control device; The control device is configured to control the blowing device 2 to be activated according to the cleaning start signal; the blowing device 2, the air outlet of the blowing device 2 is disposed at an edge of the windshield 5 for conveying to the windshield Airflow

[0026] The automatic cleaning monitoring camera provided by the utility model blows off the attachment on the front windshield by the blowing device 2, so that the shooting picture is always clear, and according to the identification device 4, it is determined whether there is any attachment on the front windshield, and then passes through The control device 3 controls the opening and closing of the blowing device 2: when an attachment adheres to the identification device 4, it determines that there is an attachment on the front windshield 5, and sends a signal to the control device 3, and the blowing device 2 is activated by the control device 3. When the attachment on the identification device 4 is blown away, it is determined that there is no deposit on the front windshield 5, a signal is sent to the control device 3, and the blower 2 is turned off by the control device 3, and the front cover glass of the camera is automatically cleaned. 5 effects. It can be understood that, in order to ensure the effect of blowing, the identification device 4 is installed under the windshield 5, the air outlet 24 of the blowing device 2 is at the upper edge of the windshield, and the wind blows through the windshield from the top and the bottom, and the identification device The wind gradually decreases, and the attachment on the windshield is blown away, and may fall on the identification device, so the former is blown clean faster than the latter, so the blowing device is closed, before The windshield has been blown clean.

[0027] In the embodiment provided by the present invention, the control device 3 includes a microcontroller and the like, the identification device 4 is connected to the input end of the single chip microcomputer, the blowing device 2 is connected to the output end of the single chip microcomputer, and the power of the entire control circuit is from the camera power supply. Conversion.

In the embodiment provided by the present invention, the identification device 4 includes a humidity sensor, and when the humidity exceeds a preset value, the humidity sensor determines that there is water on the windshield. The humidity sensor is mounted on the lower edge of the windshield 5, and there is a guide groove between the windshield and the humidity sensor, and the sensing surface of the humidity sensor and the groove bottom of the guiding groove are in a plane, so that the wind can be blown from the windshield The water flows through the humidity sensor to ensure that the humidity sensor will not be blown dry if the front windshield is not blown dry, so that the water removal effect is better.

In another embodiment provided by the present invention, the identification device further includes: a dust sensor for determining whether there is dust on the front windshield to achieve the effect of automatically removing dust attached to the front windshield.

[0030] Preferably, in the embodiment provided by the present invention, the automatic cleaning camera further includes: a wireless signal receiving device, configured to receive a blowing device startup request sent by the user. The wireless signal receiving device is connected to the input end of the single chip microcomputer, and sends a command to the single chip microcomputer through the received remote control signal to control the start and stop of the air blower, thereby avoiding the situation that the front cover glass cannot be cleaned when the sensor is damaged, before cleaning The glass cover provides a double guarantee.

[0031] As shown in FIG. 1 and FIG. 2, the air blowing device 2 includes: a housing 25 disposed above the camera body 1 and connected to the housing 11 of the camera body to form a cavity; 21, the air blower is disposed in the cavity; the air inlet hole 23, the air inlet hole 23 is disposed on the housing; the air guiding cover 22, the air guiding cover is disposed at an air outlet of the air blower 21. And in close contact with the air outlet of the air blower for guiding the flow of the gas to blow the wind toward the front windshield 5.

[0032] Preferably, the air outlet 24 is disposed on the upper edge of the windshield to achieve the effect of blowing from top to bottom, and the blower 21 is mounted above the camera body to shorten the blower to the air outlet. A distance of 24 to increase the efficiency of the blower.

[0033] In the embodiment provided by the present invention, a blowing port 24 is formed between the air guiding cover 22 and the windshield. In order to make the air blowing effect better, the width of the air outlet 24 is greater than the front. The width of the glass, so that the entire front windshield can be blown by the wind.

[0034] Preferably, the air inlet 23 faces downward to block rainwater from entering the blower 21 from the side. [0035] Preferably, the air guiding cover has a panel opposite to the air outlet of the air blower, and the area of the panel is larger than the area of the air outlet of the air blower to ensure that the wind blown from the air blower completely acts on the panel. When the high velocity wind generated by the blower 21 impinges on the panel raft, the water in the wind belt is separated from the wind, the water droplets are attached to the panel, and are blown by the wind toward the edge of the panel, and finally through the guide trough on the panel. It will flow out to ensure the blowing effect and make the monitoring picture clearer.

[0036] In summary, the embodiment provided by the present invention uses a humidity sensor and a dust sensor to determine whether there is water, dust, or the like on the front windshield. When there is an attachment, a start signal is sent to the single chip microcomputer to start the air blower. Finally, the wind generated by the blower is blown from the upper edge of the windshield to the lower edge of the front windshield by the wind guide cover. Through the improvement of the air guiding cover and the air inlet, the quality of the wind generated by the blowing device on rainy days is improved, so as to improve the quality of the monitoring picture. In addition, the remote control blower is blown through the wireless signal receiving device, thereby avoiding the damage of the sensor and the inability to clean the front windshield, which provides a double guarantee for cleaning the front windshield.
