[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] This utility model discloses a burner ignition flame detection device, such as Figure 1-5 As shown, it includes a housing 1 installed on the burner and a flame detector 4 located inside the housing 1 to detect the ignition flame of the burner.

[0022] Fixing rods 2 are fixedly installed on both sides of the outer surface of the outer shell 1 near the opening of the outer shell 1. Connecting sleeves 201 are fixedly installed on opposite sides of the two fixing rods 2. First springs 202 are fixedly installed on opposite sides inside the two connecting sleeves 201. Connecting rods 203 are fixedly installed on opposite ends of the two first springs 202. Parts of the two connecting rods 203 are located inside the two connecting sleeves 201, and the other parts of the two connecting rods 203 are located outside the two connecting sleeves 201. When the connecting rods 203 move toward the first springs 202, they will compress the first springs 202.

[0023] Each of the two connecting rods 203 has a mounting plate 204 at one of its opposite ends. A cleaning cotton pad 205 is attached to one of the opposite sides of each mounting plate 204. As the flame detector 4 moves, it moves between the two mounting plates 204, which in turn pushes the two mounting plates 204 away from each other. This causes the two connecting rods 203 to compress the two first springs 202. Through the elasticity of the first springs 202, the two cleaning cotton pads 205 come into contact with the flame detector 4. As the flame detector 4 moves, the cleaning cotton pads 205 can wipe the surface of the flame detector 4.

[0024] A miniature electric actuator 101 is fixedly installed inside the outer casing 1, and a movable plate 102 is fixedly installed at the output end of the miniature electric actuator 101. The miniature electric actuator 101 can push the movable plate 102 to move.

[0025] The movable plate 102 is fixedly connected to the flame detector 4 on the side away from the miniature electric actuator 101. When the movable plate 102 moves, it can drive the flame detector 4 to move, so as to push it to the outside of the housing 1 or move it to the inside of the housing 1.

[0026] A fixed pipe 3 is fixedly installed on the outer surface of the outer shell 1 on the side away from the opening of the outer shell 1, and a gas supply pipe 302 is fixedly installed on one side of the outer surface of the fixed pipe 3.

[0027] A piston rod 103 is fixedly installed on one side of the movable plate 102 located on the miniature electric actuator 101. A part of the piston rod 103 is located inside the housing 1, and the other part of the piston rod 103 is located inside the fixed tube 3. When the movable plate 102 moves, it will drive the piston rod 103 to move. A piston 301 is fixedly installed on one end of the piston rod 103 located inside the fixed tube 3. When the piston 301 moves inside the fixed tube 3, it can spray the air inside the movable tube through the air supply pipe 302 toward the flame detector to blow away the smoke and dust on the surface of the flame detector 4 during the process of moving toward the housing 1.

[0028] An installation sleeve 2012 is fixedly installed on the side of the outer surface of the mounting plate 204 away from the cleaning cotton block 205. Telescopic sleeves 2013 are fixedly installed on both sides of the outer surface of the mounting sleeve 2012, and both telescopic sleeves 2013 are connected to the mounting sleeve 2012. A second spring 2014 is fixedly installed on the opposite side of the two telescopic sleeves 2013, and an installation head 2015 is fixedly installed on the opposite end of the two second springs 2014. When the two installation heads 2015 move away from each other, they will compress the two second springs 2014.

[0029] Two mounting heads 2015 are fixedly mounted with movable rods 2016 on one side of the second spring 2014. Two mounting holes 2011 are opened on the outer surface of the connecting rod 203. Pulling the two movable rods 2016 will move the two mounting heads 2015 away from each other. Then, the mounting sleeve 2012 is put on the outer surface of the connecting rod 203 and the two movable rods 2016 are released. The compressed second spring 2014 will push the mounting head 2015 to move and reset, so that the mounting head 2015 can be inserted into the mounting hole 2011 to complete the connection between the mounting plate 204 and the connecting rod 203.

[0030] Both movable rods 2016 have handles fixedly installed at one end extending to the outside of the telescopic sleeve 2013, and the size of the mounting head 2015 is the same as the size of the mounting hole 2011.

[0031] Two protective plates 1011 are hinged at the opening of the housing 1. The two protective plates 1011 can rotate at the opening of the housing 1 to prevent external impurities from entering the housing 1 when the flame detector 4 moves into the housing 1.

[0032] Furthermore, each of the two protective plates 1011 is slidably connected to a movable block 1012 on one side of the opening of the outer shell 1. The movable plate 102 is hinged to two support arms 1013 on one side of the flame detector 4, and the two support arms 1013 are respectively hinged to the two movable blocks 1012. When the movable plate 102 moves the flame detector 4 toward the outside of the outer shell 1, the two support arms 1013 can push the two protective plates 1011 to rotate in the opposite direction to the opening of the outer shell 1, so that the flame detector 4 can move to the outside of the outer shell 1 through the opening of the outer shell 1. When the movable plate 102 moves the flame detector 4 toward the inside of the outer shell 1, the two protective plates 1011 will rotate toward the opening of the outer shell 1 to cover the opening of the outer shell 1.

[0033] The working principle of this utility model is as follows: the miniature electric actuator 101 pushes the movable plate 102 and the flame detector 4 to move towards the outside of the outer shell 1. The two support arms 1013 can then push the two protective plates 1011 to rotate in opposite directions towards the opening of the outer shell 1, so that the flame detector 4 can move through the opening of the outer shell 1 to the outside of the outer shell 1 to detect the flame of the burner. When the flame detector 4 is not needed, the miniature electric actuator 101 can drive the movable plate 102 and the flame detector 4 to move towards the inside of the outer shell 1. During this process, the cleaning cotton 205 can wipe the surface of the flame detector 4, and at the same time, the piston 301 will move inside the fixed tube 3 to spray the air inside the movable tube towards the flame detector 4 through the gas supply pipe 302, which, together with the cleaning cotton 205, cleans the soot on the surface of the flame detector 4.
