When the washings are more, a plurality of pulse radars 2 can be started to work at the same time. In the present embodiment, the infrared sensors 3 are provided on both end faces of the cylinder 1.
Preferably, the outer circumference of the cylinder is provided with a mounting groove 4, and the pulse radar 2 is disposed in the mounting groove 4. In the present embodiment, the mounting groove 4 penetrates the cylindrical wall of the cylindrical body 1 in the axial direction. Specifically, the outer periphery of the barrel in this embodiment is provided with a plurality of flat cut edges at intervals in the circumferential direction, an annular outer wall is provided outside the flat cut edges, the annular outer wall is integrated with other parts of the barrel 1, and covers the flat cut edges to form mounting grooves 4 with the flat cut edges. Pulse radar 2 sets up in mounting groove 4, can form the protection to pulse radar 2 through the outer wall of barrel 1. Preferably, both ends of the mounting groove 4 may be sealed by stoppers or other structures.
The barrel body further comprises water passing holes 5 which penetrate through the barrel body 1 along the radial direction, the water passing holes 5 are divided into a plurality of water passing areas along the circumferential direction, and the water passing areas and the pulse radar 2 are alternately arranged along the circumferential direction of the barrel body 1. Through the position of rational arrangement water hole 5 and pulse radar 2, both can guarantee pulse radar 2 and normally work, guarantee the accuracy and the reliability that the interior foreign matter of washings detected, can avoid pulse radar 2 again and cross and produce adverse effect each other between the water hole 5, improve the performance of inner tube.
