Technical Field

The invention belongs to the technical field of hand-pull starting internal combustion engine high-pressure cleaning machines, and particularly relates to a pressing type energy-saving speed regulating system of a high-pressure cleaning machine.

Background

The hand-pull starting high-pressure cleaning machine for the internal combustion engine generally runs at a constant rotating speed. In the idle state, the gasoline engine has high rotation speed, so that the fuel consumption is excessive and the noise is high. The operator can reduce the rotating speed of the no-load state by manually operating the speed regulating mechanism (the oscillating rod of the gasoline engine), so that the gasoline engine keeps running at a low rotating speed. In the actual use process, the method of allowing the operator to frequently operate the speed regulating mechanism by hand causes a lot of inconvenience in use. The mode of operating the speed regulating mechanism is replaced by electric control speed regulation in the existing market, and although the problems of complexity and inconvenience caused by manual operation of the speed regulating mechanism are solved, the problem of cost increase is brought.

Example 2

The utility model provides a high pressure cleaner pressure dynamic formula energy-conserving speed governing system, wherein governing valve 4 include valve body 6, valve body 6 installs on steel sheet support 3 through mounting nut 14, is connected with water supply connector 7 at the entry end of valve body 6, water supply connector 7 is connected with high-pressure hose 2's play water end, water supply connector 7's play water end department is provided with push rod 8, push rod 8 is located valve body 6. The push rod 8 comprises a pushing portion rod body 15 and an adjusting portion rod body 16, and a plane structure used for preventing rotation is arranged on the adjusting portion rod body 16. A rod body 15 of a pushing part in the push rod 8 is sleeved with a sealing ring 9 and a sealing retainer ring 10, and the sealing ring 9 and the sealing retainer ring 10 are positioned between the rod body 15 of the pushing part and the valve body 6. The rod body 16 of the adjusting part is sleeved with a compression spring 11, and the compression spring 11 is positioned between the valve body 6 and the rod body 15 of the pushing part. The adjusting part rod body 16 on the push rod 8 penetrates through the valve body 6 and then extends out, the end face, penetrating out of the valve body 6, of the adjusting part rod body 16 is connected with a limiting nut 12, the end portion of the adjusting part rod body 16 is connected with an extension spring 13, and the other end of the extension spring 13 is connected with a gasoline engine oscillating rod 5.
