Description
Technical field
The utility model relates to a kind of injector, particularly relates to the injector of alert usefulness.
Technical background
The injector of now alert usefulness was owing to both can subdue the other side such as suspect etc., be unlikely to again to cause unnecessary personal injury to the other side, so be used widely police circles, but the injector of alert usefulness mainly is the incorporate device of metal pot type at present, its characteristic feature is, main part is the high pressure tank body that metal is made, pressure and liquid wherein unite two into one, the jar mouth forms through the high pressure parcel with metal, at the jar mouth nozzle is set, what have adds the nozzle lid on nozzle, the hand device is set above the lid.This structure that generally adopts has several significant disadvantage, the firstth,, liquid in the tank body has been used and how much has been had no way of finding out about it, this just causes sometimes may cause waste, and What is more, what sometimes police carried may be the inner injector that should scrap that has not had liquid, can't use; The secondth,, this kind tank body can't be realized using repeatedly, after internal liquid has sprayed, can't realize once more canned; The 3rd is, pressure and liquid are mixed, and must a pressurising finish, and scraps otherwise promptly can cause.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provide a kind of and can see the internal liquid amount, can repeat the canned novel injector that uses repeatedly after using up, and this emitter construction is simple as far as possible, cost is cheaper, is convenient to the user from line operate.
The purpose of this utility model is achieved in that a kind of plunger type can repeat the visual alert injector of using in canned inside, form by tank body and shower nozzle, described shower nozzle is provided with nozzle, a plunger is set in described tank body, tank body is divided into two not connected parts up and down under the obstruct of plunger, top is the liquid storehouse, the bottom is the gas storehouse, opening in the tank body upper end is provided with internal thread, have the external screw thread with the tank body screw-internal thread fit in the bottom of described shower nozzle, shower nozzle and tank body screw by described internal and external threads.Be provided with a check valve that is used to inflate in the bottom of tank body.On described tank body, leave the window that to see tank interior.
Described tank body can be made for plastics class transparent material.
The described window of tank interior of can seeing can be accomplished in several ways, such as directly on tank body, offering, perhaps when the tank body material is described plastics class transparent material, spraying during shell the standby gummed paper hide the way that need reserve position of window and reserve, the alert injector of using is because of the uniform requirement spray black, can realize by above-mentioned way, if when not needing to spray, material itself just can realize seeing the purpose of inner liquid level, also can outside tank body, add a shell, on cover housing, offer window.On window, can portray scale.
Described plunger is I-shaped, and " worker " word has annular groove on two " horizontal strokes " up and down, is embedded with O-ring seal on this groove.
The button of described shower nozzle is located at the shower nozzle side, shower nozzle is provided with one section baffle plate, shower nozzle top is provided with a screens projection, shower nozzle is provided with nozzle cap, the button positions of corresponding shower nozzle is provided with a hole on the nozzle cap, the corresponding nozzle position also is provided with the hole of a suitable size on the nozzle cap, nozzle cap can rotate on shower nozzle, the nozzle cap inside top surface is provided with two thrust projectioies, treat the time spent at injector, the button of hole on the nozzle cap on the shower nozzle exposes it, when injector time spent not, nozzle cap is rotated, slide in the interval that two the thrusts projection of screens projection on the shower nozzle on nozzle cap limits, make hole on the nozzle cap facing to the baffle plate on the shower nozzle, and this moment, nozzle was also covered by nozzle cap.
During use, at first screw off shower nozzle, liquid such as capsicum water etc. are injected in the liquid storehouse from tank body top to tank body, subsequently shower nozzle are screwed, then, be pressed into gas by the check valve that is located at tank base to the gas storehouse, when preparing to use, make button expose the nozzle cap rotation, the hole of corresponding nozzle is also over against nozzle on this moment nozzle cap, after pressing the button, the high pressure in gas storehouse impels plunger to move up, and then the liquid in compressing liquid storehouse is through the nozzle ejection.By the window of on tank body, offering, can see the residing position of liquid level in the liquid storehouse.
The utility model is made owing to transparent materials such as having adopted plastics, broken away from the high-pressure metal bottle structure that people all the time can't break away from, not only realized to see the effect of internal liquid amount, and way by liquid storehouse and gas storehouse are separated, realized separating of pressure and liquid, thereby realized to repeat canned use repeatedly, and the utility model is simple in structure, and under the better situation of function, cost is cheaper on the contrary, be convenient to operation, the utility model compact conformation, volume is changeable, and some police strength departments have all given very high evaluation to this structure, title is broken the normal procedure, and cost performance is very high.
