One end of the rotating shaft 9 located in the receiving groove 3 is connected to a connecting plate 10 by means of welding, screwing, or integral molding, and the side of the connecting plate 10 away from the rotating shaft 9 is connected to the probe 1 by means of screwing, clamping, etc., so that when the rotating shaft 9 rotates, the probe 1 can rotate synchronously with the rotating shaft 9 on the connecting plate 10.

[0045] When the cylinder cover 4 covers the notch of the accommodating groove 3, the cleaning sheet 7 will be closely attached to the outer surface of the probe 1, the outer wall of the flexible sealing ring 8 will be closely attached to the groove wall of the accommodating groove 3, and the outer wall of the flexible sealing ring 8 will be attached to the side wall of the probe 1. At this time, the rotating shaft 9 is driven to rotate by an external driving device such as an electric, manual or other mechanical method, so that the probe 1 can be rubbed against the cleaning sheet 7 and the flexible sealing ring 8, thereby achieving the purpose of improving the cleaning effect on the probe 1.

[0046] Example 7

[0047] like Figure 2 As shown, on the basis of the above-mentioned embodiment 6, in this embodiment, a wire hole 11 is opened at the end of the rotating shaft 9 away from the cylinder cover 4; the wire hole 11 extends along the end of the rotating shaft 9 away from the cylinder cover 4 to the end of the rotating shaft 9 close to the cylinder cover 4, and the wire hole 11 passes through the connecting plate 10.

[0048] Exemplarily, during the implementation, a wire hole 11 is opened at one end of the rotating shaft 9 away from the barrel cover 4, and the wire hole 11 extends axially along the rotating shaft 9 until it is close to the position of the connecting plate 10, and the wire hole 11 completely penetrates the connecting plate 10. When in use, the signal transmission cable of the probe 1 is inserted through the wire hole 11, then passes through the inside of the connecting plate 10, and finally connects to the probe 1. The cable can be flexibly moved with the rotation of the rotating shaft 9 and the connecting plate 10, thereby effectively reducing the risk of the cable being entangled, pulled or damaged during the rotation of the probe 1, thereby extending the service life of the cable and reducing the purpose of interruption of the monitoring of the probe 1 due to cable failure.

[0049] Example 8

[0050] like Figure 4 As shown, based on the above-mentioned embodiment 1, in this embodiment, the probe 1 is arranged in the notch of the accommodating groove 3; the tube cover 4 is provided with an accommodating groove 12 on the side close to the probe 1; when the tube cover 4 is closed to the notch of the accommodating groove 3, the probe 1 is located in the accommodating groove 12.

[0051] For example, during the implementation, the probe 1 is arranged at the notch position of the accommodating groove 3. This makes the probe 1 closer to the inside of the combustion chamber, so that the probe 1 can more directly monitor the flame state in the combustion chamber, thereby improving the accuracy of the monitoring result of the probe 1.

[0052] Similarly, a receiving groove 12 is provided on the side of the barrel cover 4 close to the probe 1, and the shape and size of the receiving groove 12 can just match the probe 1. When the barrel cover 4 is closed to cover the notch of the receiving groove 3, the probe 1 is safely received in the receiving groove 12 on the barrel cover 4 and is properly protected.
