[0032] The elastic assembly 207 comprises a spring 207a fixedly connected with the lower surface of the valve cover 206, and the lower end of the spring 207a is fixedly connected with the adjusting diaphragm 204, the adjusting diaphragm 204 is movably connected with four groups of limiting rods 207b in the inside, the lower ends of the limiting rods 207b are fixedly connected with the inner wall bottom of the circular groove 102, and the upper end surfaces of the four groups of limiting rods 207b are movably connected with the lower surface of the valve cover 206. Through the elastic force of the spring 207a, the adjusting diaphragm 204 is tightly attached to the inner wall bottom of the circular groove 102, so that the output hole 203 is hidden in the inside of the square groove 103, and the internal pressure of the crankcase is isolated from the outside

[0033] Further, a plurality of bolts 208 are threadedly connected in the inside of the valve cover 206, and the bolts 208 are connected with the cylinder head cover 101 through threads, and the threaded rotation of the bolts 208 can flexibly disassemble the valve cover 206 from the surface of the cylinder head cover 101, so that the maintenance is facilitated.

[0037] During use, when the pressure inside the crankcase is too high, the air pressure can push the intake pipe 201 upward, so that the block 202 drives the output hole 203 to move upward inside the square groove 103. At the same time, the regulating diaphragm 204 fixedly connected to the block 202 moves upward on the surface of the outlet pipe 105, thereby connecting the output hole 203 with the outlet pipe 105, so that the pressure inside the crankcase enters the output hole 203 through the intake pipe 201, and then enters the outlet pipe 105 to push the cover plate 107 open and discharge it to the outside, thus relieving the pressure. After completion, the regulating diaphragm 204 moves downward under the elastic force of the spring 207a and the limiting effect of the limiting rod 207b, so that the block 202 drives the output hole 203 to slide into the square groove 103 and cut off the connection with the outlet pipe 105, thereby isolating the inside and outside of the crankcase, and controlling the internal pressure of the crankcase within the normal range, which can effectively reduce the crankcase pressure and play a pressure relief role.
