The specific embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 2-7:
The plug of backpack power sprayer; The medial surface that the bottom that the inwall of blocking cap 10 is provided with internal thread 111, outer wall is provided with external screw thread or buckling groove 109, diapire 107 is provided with the gasket seal zone with the dewatering outlet sealing; The sidewall of the blocking cap 10 outside the gasket seal zone is provided with several path 10s 8 that connects blocking cap 10 diapires 107, is spirally connected in the bottom of blocking cap 10 outer walls or is connected with kuppe 20.
The concrete structure of above-mentioned blocking cap 10 is: the inwall of hollow circular cylinder 101 is provided with internal thread 111; Be evenly equipped with the riser 103 that several radioactivity are provided with on the baseplane 102 of hollow circular cylinder 101; The outside 105 of riser 103 is one-body molded to have annulus 104, inboard 106 not overlap; The one-body molded plectane 107 that each riser 103 of connection is arranged in the bottom of each riser 103; The diameter of plectane 107 is less than the internal diameter of annulus 104; The external diameter of annulus 104 is less than the external diameter of hollow circular cylinder 101, is provided with the path 10 8 that is communicated with hollow circular cylinder 101 inner chambers between the excircle of plectane 107 and the annulus 104, is provided with buckling groove 109 or external screw thread in the junction of hollow circular cylinder 101 and annulus 104.
