Abstract
The utility model relates to an ejector capable of filling repeatedly, which consists of a jar body, a bag valve, a nozzle and a protecting cap. Liquid medicine is filled in the bag valve which is arranged in the jar body, and compressed air is filled between the bag valve and the jar body; the nozzle is located at the upper end of the jar body and is arranged at an aerosol valve of the bag valve; and the protecting cap covers the nozzle. The ejector is characterized in that a charging valve which can inject compressed air into the jar body is arranged at the upper end or the side face of the jar body; and a pressure indicator which can display the air pressure in the jar body is arranged at the lower end of the jar body. The ejector can fill compressed air into the jar body from the charging valve and the pressure of the compressed air in the jar body can be displayed on by the pressure indicator. In this way an operator can estimate the liquid medicine amount in the bag valve and judge whether to fill liquid medicine and compressed air again. The ejector can fill liquid medicine and compressed air repeatedly, can be used for a plurality times and can display the pressure in the jar body. The ejector is applicable for police lacrimation and civil spraying.
Description
Technical field
The utility model relates to the canned liquid injector, and especially a kind of tear-gas is with reusablely repeating canned injector.
Background technology
Existing lacrimation ejector generally is made up of tank body, bag valve, nozzle and protective cap, and tear-gas liquid medicine pours in bag valve, is full of compressed air in solid.This injector is under compressed environment tank body and the assembling of bag valve to be linked together and seal when canned tear-gas liquid medicine, injects tear-gas liquid medicine then in the bag valve.During use, press nozzle, the liquid medicine in the bag valve sprays under the effect of tank body compressed air.Owing to need compressed-air actuated environment during the canned liquid medicine of this injector, must carry out to specialized factory, pretty troublesome, therefore, they all are disposable uses, waste very big.
The utility model content
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind ofly can repeat canned use, and can show the canned injector that repeats of jar internal pressure.
For achieving the above object; the utility model adopts following technical scheme: repeat canned injector; form by tank body, bag valve, nozzle and protective cap; canned in the bag valve have liquid medicine; the bag valve is positioned at tank body; between bag valve and tank body, be full of compressed air; nozzle is positioned at the aerosol valve place that the tank body upper end is contained in bag valve; protective cap covers nozzle; it is characterized in that in tank body upper end or the side be equipped with can be in tank body the charging valve of injecting compressed air, the pressure display unit that can show the tank body inner air pressure is housed in the tank body lower end.
In such scheme, described pressure display unit adopts gas gauge, and this Pressure gauge is positioned at the tank base pit, and is fixed on by cap nut on the through hole of pit bottom, offers the gas channel that will be communicated with in Pressure gauge and the tank body in cap nut.
In such scheme, described charging valve comprises a valve seat, this valve seat is a tube structure, be fixed on the other through hole of tank body upper end nozzle, in the cylindrical shell of valve seat, be provided with the dividing plate of a band aeration aperture, in the cylindrical shell of the inner valve seat of aeration aperture, a spool is housed, gapped between this spool and the valve seat cylinder inboard wall, spool and aeration aperture opposing end faces are provided with at least one circle boss, be provided with sealing gasket between spool and the aeration aperture end face, have through hole with aeration aperture corresponding position in the sealing pad, be equipped with in the other end of spool and force spool to be pressed on envelope air spring on the aeration aperture end face.
In the cylindrical shell of above-mentioned aeration aperture outer end valve seat, can be provided with the buckle closure that an energy covers the aeration aperture, be connected with engage thread between the cylinder inboard wall of this buckle closure and valve seat, be provided with small sealing ring between the little outer end of hole of buckle closure and aeration.
Cylindrical shell bottom at above-mentioned valve seat can be provided with spring base, has passage on the cylinder lateral wall of valve seat below spool, in the cylindrical shell of the valve seat of described envelope air spring between spool lower surface and spring base.
Described in the utility model repeat canned injector can be from charging valve bottled, compressed air in tank body, and can know the pressure of tank body compressed air, thereby estimate the amount of liquid medicine in the bag valve that decision is canned once more soup and compressed air whether from Pressure gauge.This injector can repeat canned soup and compressed air, can be repeatedly used, and can show the tank body internal pressure, is suitable for alert use tear-gas, civilian spraying use, is particularly suitable for the sprayer of medicine, coating, makeup and chemicals.
