increasing the air pressure: through set up slidable connection's piston block 30 in go-between 29 department, when the inside atmospheric pressure of gasbag 27 reachd the certain degree, just can promote piston block 30 and slide from the inside of go-between 29, let high-pressure gas strike the inside of jet-propelled pipe 25 fast, can jet-propelled pipe 25 with high-pressure gas quick spraying away, let the impurity in the clearance gap more complete.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
