[0016] Figure 2 It is a schematic diagram of the structure of the cleaning agent nozzle. DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] As shown in the figure, the tear gas sprayer with a cleaning function in this embodiment includes a front shell 1, in which a tear gas bag 2 and a high-pressure gas 3 for squeezing the tear gas bag are installed, and a tear gas spray head 4 connected to the tear gas bag is provided at the front end of the front shell. The tear gas sprayer with a cleaning function in this embodiment also includes a rear shell 5 connected to the rear end of the front shell, in which a cleaning agent 6 is installed, and a cleaning agent spray head 7 is provided at the end of the rear shell.

[0019] In a specific implementation, the front housing and the rear housing may be formed in an integral structure, or the front housing and the rear housing may be connected into one by a threaded connection or the like.

[0020] The tear gas sprayer with cleaning function in this embodiment can not only spray tear gas at bad guys, but also, after subduing the bad guys, spray cleaning agent at the bad guys by pressing the cleaning agent spray head to relieve or eliminate the continuous damage of the tear gas.

[0021] As an improvement to the above embodiment, the cleaning agent is a mixed solution composed of soda water and menthol ethanol solution. In a specific implementation, the mass concentration of sodium bicarbonate in the mixed solution is preferably 2-5%, such as the mass concentration of sodium bicarbonate can be 2%, 3%, 4% or 5%; the mass concentration of menthol is preferably 1-5%, such as 1%, 2%, 3%, 4% or 5%. The mass concentrations of sodium bicarbonate and menthol in the mixed solution can also be adjusted accordingly according to the concentration of the tear gas. The role of ethanol in the mixed solution is to dissolve menthol, and its content can ensure that menthol is completely dissolved; at the same time, ethanol can also dissolve the sprayed tear gas, which can improve the cleaning efficiency and accelerate the elimination of tear gas damage.

[0022] The cleaning agent in the present improvement can quickly relieve and eliminate the irritation, burning pain, stinging and other sensations caused by the tear gas to the human body. Compared with the prior art of using clean water to relieve the damage caused by the tear gas, the cleaning agent in the present improvement is more effective and has a better effect.

[0023] As an improvement on the above embodiment, the cleaning agent nozzle includes a nozzle seat 8 fixed on the end of the rear shell body, a piston cylinder 9 fixed in the nozzle seat, a piston 10 slidingly sealed with the piston cylinder, a tension spring 11 located in the piston cylinder, a piston rod 12 connected to the piston at the lower end, a pressure head 13 connected to the upper end of the piston rod, a cleaning agent nozzle 14 arranged on the pressure head and a protective cover 15 buckled on the nozzle seat, one end of the tension spring is fixed to the upper end of the piston cylinder, and the other end of the tension spring is fixed to the piston rod on one side of the piston, a first one-way valve 16 and a suction tube 17 connected to the first one-way valve are provided at the lower end of the piston cylinder, a second one-way valve 18 is provided at the lower end of the piston rod, and an infusion hole 19 connected to the second one-way valve is provided in the middle of the piston rod, and the outlet of the infusion hole is connected to the inlet of the cleaning agent nozzle. When the tension spring is in the contracted state, 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 to prevent the liquid in the liquid suction chamber from flowing back to the rear housing, and the second one-way valve is used to prevent external gas from entering the washing liquid chamber. Of course, in different embodiments, the cleaning agent nozzle can also adopt other existing structures.

[0024] When it is necessary to spray the cleaning agent, open the protective cover and repeatedly press the pressure head 13 downward. The downward movement of the pressure head pushes the piston downward, and the piston discharges the gas in the liquid suction chamber. The pressure head is released and the piston moves upward under the tension of the tension spring. At this time, a vacuum is formed in the liquid suction chamber, and the air pressure in the rear shell presses the cleaning agent into the liquid suction chamber. Since 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 move the piston downward again, the cleaning agent in the liquid suction chamber is pressed into the infusion hole and then sprayed out from the cleaning agent nozzle. In a specific implementation, the cleaning agent nozzle can adopt an atomizing nozzle, which can make the cleaning agent spray evenly on the cleaned part, with faster cleaning speed and better effect. The cleaning agent nozzle in this improvement has a simple structure, high reliability and is easy to use.

[0025] As an improvement to the above embodiment, the nozzle seat and the rear housing are connected by threads, so that the cleaning agent nozzle can be easily disassembled to add cleaning agent. A sealing gasket 21 is arranged in the nozzle seat to match the end surface of the rear housing to prevent leakage of cleaning agent.

[0026] As an improvement to the above embodiment, a miniature flashlight 22 is further provided on the front housing, and the lamp head of the miniature flashlight is oriented in the same direction as the tear gas spray head. This improvement enables the illumination function of the miniature flashlight to improve the tear gas spray accuracy when the tear gas sprayer with a cleaning function is used at night.

[0027] As an improvement to the above embodiment, the rear housing is further provided with an observation window 21 for observing the remaining amount of the cleaning agent. Through the observation window, the insufficient remaining amount of the cleaning agent can be found in time, so that the cleaning agent can be replenished in time for normal use.

[0028] Of course, in a specific implementation, the front shell can also be provided with an observation window 22 for observing the remaining tear gas in the tear gas bag, and the insufficient tear gas remaining can be found in time through the observation window. When the remaining tear gas is insufficient, the tear gas nozzle and the tear gas bag can be disassembled, and the tear gas bag can be refilled with tear gas. After the tear gas is filled, the tear gas nozzle and the tear gas bag are reinstalled in the front shell, and then high-pressure gas is injected into the front shell through the inflation valve 23 provided on the front shell, and the tear gas ejector can be used again.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
