Piston rod end to the packing device of the hand held sprayer

摘要

according to the invention is a hand sprayer of the special load coil packing device and packing device is in the structure of the course of drug action, the strength weak, the elderly can easily spray process. to solve the problem, the purpose of the research. according to the invention, the above in order to achieve the purpose of hand sprayer of the eastern apex of the sealing device box, to take the air inlet (5) and a ball valve (6) is formed in the circular groove, and outsourcing (7) to form a packing support and (2) a load (1). as far as possible, be combined with the apex of the packing support. (2) in the form of (7), a ring type packing (3) is a kind of outsourcing, the type of the packing cylinder (4) in the insert so as to be close to the characteristics of manual ubd84ubb34uae30uc758. the eastern apex filler. for the new show.the above configuration of the contact, and the amount of a suction and compression when the watertight, the area to maintain the cylinder and to the touch state of the special campaign to get its own compared with the relative contact friction force can be reduced.
