DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a technical solution: a police handheld electric tear gas sprayer, comprising a tear gas sprayer body 1, a high-voltage DC pump 2, a control circuit board 3, a toggle switch 4 and a battery 5.

[0026] The tear gas sprayer body 1 is provided with a partition 6, and the partition 6 divides the tear gas sprayer body 1 into two chambers, namely a first chamber 61 and a second chamber 62 for containing tear gas;

[0027] The first cavity 61 is provided with a high-voltage DC pump 2, and a control circuit board 3 is installed on the side of the high-voltage DC pump 2, and the control circuit board 3 is electrically connected to the high-voltage DC pump 2; the battery 5 is fixed on the upper end of the partition 6, and the battery 5 is electrically connected to the control circuit board 3. In one embodiment, the battery 5 is provided with a charging port, such as Figure 1 As shown, the charging terminal interface is arranged on one side outer wall of the tear gas sprayer body 1, and a toggle switch 4 is arranged from the top surface to the one side outer wall of the tear gas sprayer body 1, and the control circuit board 3 is also electrically connected to the toggle switch 4; the toggle switch 4 includes a toggle switch protection cover 41 and a toggle switch 42, and a groove 43 connected to the toggle switch 42 is arranged in the toggle switch protection cover 41, and the groove of the toggle switch protection cover is plugged together with the toggle switch,

[0028] The tear gas bottle 9 of the tear gas sprayer main body 1 is rotatably mounted on the lower end of the partition 6, and the rotatable mounting is a threaded connection. The upper end of the tear gas bottle 9 is provided with an external thread, and the partition 6 is provided with an internal thread. The partition 6 and the tear gas bottle 9 cooperate with each other to form a threaded connection. The tear gas bottle 9 is used to contain tear gas, and the second volume chamber 62 is an internal space formed by the tear gas bottle 9 and the partition.

[0029] The signal is sent to the control circuit board 3 through the toggle switch 4, and the control circuit board 3 controls the high-voltage DC pump 2 to perform the spraying action. In the utility model, the high-voltage DC pump 2 acts on people at close range. By adjusting the toggle switch to a smaller level, it will not accidentally injure people's eyes due to excessive pressure, nor will it spread over a large area to affect surrounding police officers; when it is used for people at a long distance at high pressure, it can avoid contact with the crowd and cause a melee. The product is equipped with a battery and can be used after charging; it has a long standby time and does not affect the spraying effect. Usually, the high-pressure filling method is adopted. If the pressure is too high during inflation, the sprayed liquid may become mist instead of jet. The utility model adopts a pump as the spraying project, and the pressure of the pump can be freely adjusted by the toggle switch to avoid the formation of mist as much as possible.

[0030] like Figure 2-Figure 3 As shown, the control circuit board 3 adopts a circuit board mainly composed of control chip components. The circuit board (control circuit board 3) is fixed in the first slot on the partition 6, and the battery 5 is fixed on the second slot on the partition. The high-voltage DC pump 2 is fixed at the center position in the first cavity 61 through a support column. There are 4 support columns. The first slot is set on one side of the high-voltage DC pump 2, and the second slot is set on the other side of the high-voltage DC pump 2.

[0031] The tear gas sprayer body 1 comprises a nozzle 101, which is arranged on the other side of the upper part of the tear gas sprayer body 1. A pipe 102 is fixed in the nozzle 101, and the pipe 102 is connected to the liquid outlet of the high-voltage DC pump 2. The liquid inlet of the high-voltage DC pump 2 is connected to the liquid suction pipe 103. The high-voltage DC pump 2 generates suction force, and the liquid in the tear gas bottle is sucked through the liquid suction pipe 103, and then the tear gas is sprayed out through the nozzle through the pipe.

[0032] The tear gas bottle 9 is made of transparent plastic. The tear gas bottle 9 of the utility model is made of corrosion-resistant, high-strength transparent plastic. In one embodiment, a film is also encapsulated at the mouth of the tear gas bottle 9 to prevent the tear gas from spilling. A circular opening is provided in the center of the film, and the pipette 103 is inserted into the opening to contact the tear gas. In the prior art, each ejector is often discarded after a single use, causing material waste and environmental pressure. By replacing the tear gas bottle 9, the problem of discarding and waste is solved.

[0033] The liquid pipette 103 is a silicone hose, and a gravity ball 104 is installed at the bottom of the liquid pipette 103. The gravity ball 104 ensures that the sprayer can draw the tear gas for spraying at any angle.

[0034] The toggle switch 4 and the nozzle 101 are symmetrically mounted on both sides of the tear gas sprayer body 1 .

[0035] The device also includes a toggle switch 4, which is used for multi-stage segmented control. The toggle switch 4 is a push-type toggle switch, which is adjusted according to the up and down position of the switch, and is controlled in multiple stages (it may be a three-stage or four-stage toggle switch, etc., which may be changed according to actual conditions). The spray intensity, distance and time can be freely controlled according to the situation, reducing the difficulty of on-site handling by police officers.

[0036] The top surface of the tear gas sprayer body is provided with an LED display device 7, and the LED display device 7 is electrically connected to the control circuit board 3. In a specific embodiment of the utility model, the power display bottle 7 uses 4 LEDs to display 25%, 50%, 75%, and 100% respectively. In one embodiment, the LED display device is set as a liquid crystal display screen, and the surface of the tear gas sprayer body is provided with a protrusion, and the LED display device is fixed on the protrusion on the surface of the tear gas sprayer body. The LED display device is fixed in the protrusion to prevent the LED display device from shaking. In one embodiment, a touch switch is also provided on the surface of the toggle switch, which is unlocked by touching, and the amount of force used is used to control the amount of liquid outflow.

[0037] The partition 6 is provided with a threaded hole 8, and one end of the pipette 103 passes through the threaded hole 8 and extends into the second cavity 62. The position where the pipette 103 passes through the threaded hole is sealed with silicone to prevent the tear gas from flowing into the first cavity 61 and interfering with the control circuit board and the high-voltage DC pump.

[0038] The nozzle 101 is an oblique opening, which is an upward or downward opening. The nozzle 101 and the pipette 103 are fixed with a silicone seal, and a cover is installed on the upper end of the nozzle 101. The tear gas inlet is obliquely opened and double-protected, with an inner silicone seal and an outer cover to ensure that the tear gas will not be easily spilled, which is very convenient and highly practical.

[0039] Embodiment 2: Compared with Embodiment 1, the difference of this embodiment is that:

[0040] The pipe 102 in the nozzle 101 is opened or closed by a switch and a valve. The pipe is provided with a valve, and the switch is provided on the top surface of the tear gas sprayer body. Figure 1 As shown, the switch on the top surface sinks, and when the switch is turned on, the pipeline is opened, and when the switch is turned off, the pipeline is closed.
