A valve body of a piston type has good sealing performance, and can well seal gas and liquid in the tank body; and a unidirectional inflating liquid valve arranged on the tank body can conveniently and repeatedly fill gas and liquid, repeatedly use the tank body and save the cost.
Description
Technical field
The present invention relates to a kind of miniature extraordinary police and use the apparatus lacrimation ejector, relate in particular to a kind of improved lacrimation ejector.
Background technology
As everyone knows, lacrimation ejector belongs to miniature extraordinary police apparatus, mainly for public security police when exercising a public function, be used for quick uniform, arrest the ruffian, criminal and suspect, also can be used for self-defence simultaneously for the policeman.Injector mainly is made up of major parts such as tank body, valve body, nozzle, propellant, protective caps.Its operation principle is to rely on compressed air specified in the tank body as power source, make valve body, valve be in closed condition, and make the solvent bag be in squeezed state all the time, behind valve open, the solvent bag makes the propellant in the bag spray to target by valve from nozzle immediately under the constant voltage dynamic action.The propellant spray is penetrated on human body face, skin, dress ornament, will produce the strong impulse effect to human eye, nasal cavity, oral cavity, skin and respiratory tract sense organ, occur rapidly shedding tears, have a running nose, cough, skin and symptoms such as eyes cusalgia, expiratory dyspnea.
At present, there is following problem in the lacrimation ejector of use owing to structural reason; The one, sealing property is bad, and grown service time, often has the phenomenon of gas leakage, influence use in emergency circumstances; The 2nd, be mostly disposable use, promptly use up the dacryagogue in the tank body after, whole injector is promptly abandoned it, causes great waste, though repeatedly canned injector has also appearred in the market, more bothersome during can, and have gas leak phenomenon equally.
Summary of the invention
The objective of the invention is provides a kind of improved novel lacrimation ejector at the gas leakage of lacrimation ejector existence of the prior art and the problem of can difficulty, its good seal performance, and it is convenient to repeat can, simple in structure, long service life.
The objective of the invention is to be achieved through the following technical solutions, this novel lacrimation ejector comprises tank body, injection valve, protecting cap, the gassy fluid mouth, Pressure gauge, catheter, described tank body top is connected with injection valve, described tank base is provided with a Pressure gauge, be used for measuring the pressure in the indication tank body, describedly be provided with a unidirectional gassy fluid mouth in tank body top one side, described injection valve comprises cylinder body again, bonnet, piston body, spring, described bonnet is connected the top of cylinder body, described cylinder body is the cylindrical shape of inner wall smooth, one side of described cylinder body is provided with nozzle, the described cylinder body that is positioned at the nozzle below is provided with a baffle plate, the central authorities of described plate washer are provided with a piston rod through hole, the described liquid-through hole that on the baffle plate of piston rod bore periphery, also is provided with, be provided with a piston body in the described cylinder body, described piston body comprises piston rod, bottom piston, upper piston, described bottom piston is positioned at the plate washer bottom, be connected in the lower end of piston rod, the diameter of described bottom piston is less than cylinder diameter, be to leave the liquid flow space between bottom piston outer wall and the inboard wall of cylinder block, described upper piston is positioned at the top of baffle plate, be connected on the piston rod, described upper piston is a packed-piston, be that piston outer wall and inboard wall of cylinder block are slidingly connected, described spring is between bottom piston and cylinder base, described cylinder base is connecting a catheter that is positioned at tank body, described piston rod part is provided with a button, for improving the sealing of upper piston, can also be provided with sealing ring on the outer wall of upper piston.
Described sealing ring is a rubber ring.
When not spraying, the elastic force by air pressure in the tank body and spring promotes bottom piston and moves up, and bottom piston is close on the baffle plate, at this moment, bottom piston is all blocked the liquid-through hole on the baffle plate, and the gas-liquid in the tank body can not be overflowed, and has reached the purpose of gas-liquid in the sealed shell of tank; When needing to implement to spray, open protecting cap, hand touches the button, piston rod promotion bottom piston overcomes spring force and moves down, make bottom piston leave liquid-through hole on the baffle plate, at this moment, the highly pressurised liquid in the tank body enters cylinder body by catheter, enter between baffle plate top and the upper piston by the space between bottom piston and the inboard wall of cylinder block, liquid-through hole on the baffle plate again, spray from nozzle at last.
Can indicate pressure size in the tank body by the Pressure gauge that is installed in tank base, when pressure in the tank body and fluid low, by unidirectional gassy fluid valve filling gas and liquid in tank body.
Beneficial effect of the present invention: 1, good seal performance, because valve body adopts piston type, can realize the sealing to the gas-liquid in the tank body preferably; 2, can repeatedly charge gas-liquid easily, the recycling tank body is saved cost.
