[0030] like Figures 1 to 5As shown, the visual infrared flame detector includes: a fixing base 1, a detection head 101 is provided on the first plane of the fixing base 1, a mounting groove 103 is provided on the outer side of the first plane of the fixing base 1, and the first plane is the contact surface between the fixing base 1 and the detection head 101; a protective member 3 is arranged on the outer side of the fixing base 1, and is used to protect the detector; a cleaning member 4 is arranged on the outer side of the protective member 3, and is used to clean the protective member 3; a rotating component 2 is arranged on the outer side of the fixing base 1, and is used to provide power to the cleaning member 4. Specifically, when in use, the detector is protected by the protective member 3 to avoid heat damage during use, and then the smoke and dust attached to the surface of the protective member 3 is cleaned by the cooperation of the rotating component 2 and the cleaning member 4 to ensure accuracy during detection and avoid smoke and dust attached to the surface of the protective member 3 during use, which may cause the detector to be covered.

[0031] like Figures 1 to 5 As shown, a connecting plate 102 is provided on the outside of the fixing base 1, and there are multiple connecting plates 102. Fixing grooves are opened inside the connecting plates 102, and the fixing grooves penetrate the connecting plates 102. Specifically, the detection head 101 is spherical, and multiple detectors are provided on the outside of the detection head 101, so as to increase the detection angle and reduce the detection blind area. When in use, the fixing base 1 is connected to the wall through the connecting plate 102 to ensure the stability of the detector of the fixing base 1 during the detection process.

[0032] like Figures 1 to 5 As shown, the rotating assembly 2 includes a mounting ring 201, the mounting ring 201 is connected to the fixing seat 1, a fixing shell 204 is provided on the outside of the mounting ring 201, a gear 205 is provided inside the fixing shell 204, a connecting ring 202 is provided inside the mounting ring 201, a gear ring 203 is provided on the outside of the connecting ring 202, and the gear ring 203 is meshed with the gear 205. Specifically, the mounting ring 201 and the fixing seat 1 are connected by threads, and the mounting ring 201 limits the connecting ring 202 to prevent the connecting ring 202 from being relative to the mounting ring 202 when in use. Ring 201 is displaced, and a motor is provided on the outside of the fixed shell 204, which drives the gear 205 to rotate. The connecting ring 202 and the gear ring 203 are detachably connected. When in use, the gear ring 203 is first driven to rotate by the gear 205. Since the gear ring 203 is connected to the connecting ring 202, the position of the gear ring 203 is limited by the cooperation of the connecting ring 202 and the mounting ring 201 while the gear ring 203 rotates, thereby avoiding displacement of the gear ring 203 relative to the fixing seat 1 and ensuring stability during use.

[0033] like Figures 1 to 5As shown, the protective member 3 includes a fixing ring 301, which is arranged inside the mounting groove 103. A fixing cover 302 is provided on the outside of the fixing ring 301. The fixing cover 302 is bowl-shaped, and the open end of the fixing cover 302 is connected to the fixing ring 301. Specifically, the fixing ring 301 and the mounting groove 103 are fixed by a card slot connection or a threaded connection, which is convenient for a separate replacement of the fixing cover 302 when it is damaged, thereby reducing maintenance costs.

[0034] like Figures 1 to 5 As shown, the cleaning member 4 includes an arc rod 401, which is in multiple groups and fits the fixed cover 302. Bolts 402 are provided inside the arc rod 401, and the bolts 402 are connected to the gear ring 203. Specifically, a cleaning strip is provided on one side of the contact surface between the arc rod 401 and the fixed cover 302. The hardness of the cleaning strip is lower than that of the fixed cover 302, and the cleaning strip fits tightly to the surface of the fixed cover 302. When in use, the arc rod 401 is connected to the gear ring 203 by the bolt 402. After the connection is completed, the gear ring 203 rotates driven by the gear 205, so that the rotating gear ring 203 drives the arc rod 401 and the cleaning strip to clean the smoke and dust attached to the surface of the fixed cover 302, so as to avoid the smoke and dust adhering to the surface of the fixed cover 302 and causing the detector to be unable to detect, thereby ensuring stability during use.

[0035] like Figures 1 to 5 As shown, the fixed cover 302 is made of glass. Specifically, the fixed cover 302 is heat-insulating glass, which blocks the heat of the detector during detection, prevents the detector from being damaged by heat, and prolongs the service life of the detector.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
