Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in the drawing, the cleanable lachrymatory injector in the embodiment comprises a front shell 1, a lachrymatory bag 2 and high-pressure gas 3 for extruding the lachrymatory bag are arranged in the front shell, and a lachrymatory spray head 4 connected with the lachrymatory bag is arranged at the front end of the front shell. The cleanable lacrimation ejector in the embodiment further comprises a rear shell 5 connected with the rear end of the front shell, a cleaning agent 6 is filled in the rear shell, and a cleaning agent nozzle 7 is arranged at the end part of the rear shell.

In specific implementation, the front shell and the rear shell can be of an integrally formed structure, or the front shell and the rear shell can be integrally connected by adopting a threaded connection mode and the like.

In specific implementation, the cleaning agent can adopt clear water or soda water and the like.

The washable lacrimation sprayer in the embodiment can spray lacrimation agent to illegal criminals, can spray the cleaning agent to the illegal criminals by pressing the cleaning agent nozzle to relieve or eliminate continuous injury of the lacrimation agent after the illegal criminals are dressed, and then takes away the illegal criminals quickly, is favorable for improving the field law enforcement efficiency of policemen, and shows humanized law enforcement.

As an improvement to the above embodiment, the cleaning agent nozzle includes a nozzle seat 8 fixed on the end portion of the rear housing, a piston cylinder 9 fixed in the nozzle seat, a piston 10 in sliding sealing fit with the piston cylinder, a tension spring 11 located in the piston cylinder, a piston rod 12 whose lower end is connected with the piston, a pressure head 13 connected with the upper end of the piston rod, a cleaning agent nozzle 14 arranged on the pressure head, and a protecting cover 15 buckled on the nozzle seat, wherein one end of the tension spring is fixed at the upper end of the piston cylinder, the other end of the tension spring is fixed on the piston rod on one side of the piston, the lower end of the piston cylinder is provided with a first one-way valve 16 and a pipette 17 connected with the first one-way valve, the lower end of the piston rod is provided with a second one-way valve 18, the middle portion of the piston rod is provided with a transfusion hole 19 communicated with the second one-way valve, and the outlet of the transfusion hole is communicated with the inlet of the cleaning agent nozzle. In the contracted state of the tension spring, a liquid suction chamber 20 is formed between the piston and the lower end of the piston cylinder; the first one-way valve is used for preventing liquid in the liquid suction chamber from flowing back to the rear shell, and the second one-way valve is used for preventing external air from entering the washing liquid chamber.

When the cleaning agent needs to be sprayed, the protective cover is opened, and the pressure head 13 is repeatedly pressed downwards. The pressure head moves downwards to push the piston to move downwards, the piston discharges gas in the liquid suction chamber, the pressure head piston is loosened to move upwards under the action of tension of the tension spring, vacuum is formed in the liquid suction chamber at the moment, and the air pressure in the rear shell presses the cleaning agent into the liquid suction chamber. Because the first one-way valve can prevent the cleaning agent in the liquid suction chamber from flowing back, when the pressure head is pressed to make the piston move downwards again, the cleaning agent in the liquid suction chamber is pressed into the infusion hole and then sprayed out from the cleaning agent nozzle. The cleaning agent nozzle can adopt an atomizing nozzle in the specific implementation, the atomizing nozzle can enable the cleaning agent to be uniformly sprayed on the cleaned part, the cleaning speed is higher, and the effect is better. The improved cleaning agent spray head is simple in structure, high in reliability and convenient to use.

As an improvement to the above embodiment, the nozzle base and the rear shell are in threaded connection, so that the cleaning agent can be conveniently removed and added to the nozzle. The nozzle seat is internally provided with a sealing gasket 21 matched with the end surface of the rear shell, so that the cleaning agent can be prevented from leaking.

As a modification of the above embodiment, the front housing is further provided with a micro flashlight 22 having a base oriented in line with the lachrymatory spray head. This improvement makes when using the washable type tear sprayer night, can utilize the illumination function of miniature flashlight to improve the tear agent and spray the degree of accuracy.

As a modification of the above embodiment, the rear case is further provided with an observation window 21 for observing the remaining amount of the cleaning agent. The condition that the residual amount of the cleaning agent is insufficient can be found in time through the observation window, so that the cleaning agent can be supplemented in time, and normal use can be guaranteed during law enforcement.

In a specific implementation, the front shell can be further provided with an observation window 22 for observing the residual quantity of the lacrimatory agent in the lacrimatory agent bag, and the condition that the residual quantity of the lacrimatory agent is insufficient can be timely found through the observation window. When the residual quantity is insufficient, the lacrimatory agent nozzle and the lacrimatory agent bag can be detached, the lacrimatory agent bag is refilled with the lacrimatory agent, after the lacrimatory agent is filled, the lacrimatory agent nozzle and the lacrimatory agent bag are refilled in the front shell, then high-pressure gas is injected into the front shell through the inflation valve 23 arranged on the front shell, and the lacrimatory ejector can be used again.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
