DETAILED DESCRIPTION

[0015] like Figure 1-Figure 2 As shown, a multifunctional police sprayer includes two connected storage tanks 1. Specifically, the ends of the two storage tanks 1 that are close to each other are fixedly connected by a connecting plate 2. One of the storage tanks 1 is filled with paint, and the other storage tank 1 is filled with a mixed liquid of natural capsaicin and police tear gas. The lower halves of the two storage tanks 1 on the opposite sides are respectively provided with transparent long strip observation windows 3, so that the user can close the window to check the liquid level inside the storage tank 1, which is conducive to timely adding the corresponding liquid spray into the storage tank. The upper part of each storage tank 1 is detachably installed with a spray switch.

Moreover, for the criminal who is driving away, the paint can be sprayed onto the front windshield of the vehicle driven by the criminal, so that the driving vision of the criminal is disturbed, and the driving criminal can be effectively forced to stop, lose the ability to drive away, and achieve the purpose of stopping the criminal attack.

[0017] In this embodiment, the spray switch includes an outer cover 4 which is sleeved on the upper open end of each of the storage tanks 1. The outer wall of the storage tank 1 is provided with an external thread near its open end. The lower part of the inner wall of the outer cover 4 is provided with an internal thread which is compatible with the external thread of the storage tank. The outer cover 4 is detachably connected to the storage tank by a threaded connection.

[0018] The inner peripheral wall of the outer cover 4 is fixedly provided with a connecting sleeve 5, the lower part of the connecting sleeve 5 is fixedly provided with a limiting sleeve 6, the bottom of the limiting sleeve 6 is fixedly provided with a conical tube 7, and the outer cover, the connecting sleeve, the limiting sleeve and the conical tube are an integrated structure. An annular baffle 8 is provided at the connection part between the limiting sleeve 6 and the conical tube 7, and a spherical plug 9 adapted thereto is movably provided inside the conical tube 7, and the diameter of the spherical plug 9 is smaller than the inner diameter of the annular baffle 8. The bottom of the conical tube 7 is connected to the upper end of a vertical upper liquid pipe 10, and the lower end of the upper liquid pipe 10 extends to the bottom of the storage tank 1.

[0019] A piston cylinder 11 is slidably disposed inside the outer cover. The piston cylinder 11 includes a first connecting portion 11-1, a second connecting portion 11-2 and a third connecting portion 11-3 with outer diameters gradually increasing from top to bottom.

[0020] The outer fixed sleeve of the first connection part 11 - 1 is provided with a push switch cover 12 , and the side of the push switch cover 12 is provided with a spray hole 13 . The middle part of the inner peripheral wall of the first connection part 11 is evenly provided with a plurality of limiting fins 14 along the circumferential direction.

[0021] The outer portion of the second connection portion 11-2 is in gap with the through hole opened at the top of the outer cover 4, and the inner portion of the second connection portion 11-2 is provided with an inner sleeve 15. The lower half of the inner sleeve 15 is in sealing and sliding cooperation with the inner wall of the limiting sleeve 6. The upper portion of the inner sleeve 15 is provided with a tapered hole 16, and the inner portion of the inner sleeve 15 is provided with a column valve 17.

[0022] The column valve 17 includes a main body 17-1, the diameter of which is smaller than the inner diameter of the second connecting portion 11-2. A conical plug 17-2 matching the conical hole 16 is provided at the upper end of the main body 17-1, and a push rod 17-3 is fixedly provided at the lower end of the main body 17-1, and the diameter of the push rod 17-3 is smaller than the inner diameter of the annular baffle 8. A spring 18 is sleeved on the outer portion of the push rod 17-3, the upper end of the spring 18 is fixedly provided in the limiting groove 19 at the lower end of the inner sleeve 15, and the lower end of the spring 18 is fixedly connected to the annular baffle 8.

[0023] An annular mounting groove 20 is provided at the top of the third connecting portion 11-3, and a plurality of air inlet holes 21 are evenly opened along the circumferential direction between the mounting groove 20 and its outer edge, an elastic sealing ring 22 is provided in the mounting groove 20, and the elastic sealing ring 22 is provided with a first sealing portion 22-1 below the plurality of air inlet holes, and a second sealing portion 22-2 is provided between the inner circumferential wall of the second connecting portion 11-2 and the outer circumferential wall of the inner sleeve 15.

[0024] When the utility model is in operation, the space between the inner sleeve, the limit sleeve, the conical cylinder, the spherical plug and the column valve forms a liquid-containing chamber 23, and the space between the second connecting part and the third connecting part of the piston cylinder and the outer cover and the connecting sleeve forms an air-containing chamber 24. By pressing the push switch cover, the piston sleeve, the inner sleeve and the column valve move downward, and the push rod at the lower end of the column valve passes through the annular baffle to push the spherical plug against the bottom of the conical cylinder, thereby closing the upper liquid pipes respectively. Moreover, the conical plug at the upper part of the column valve is separated from the conical hole of the inner sleeve, so that the liquid inside the liquid-containing chamber flows upward from the gap between the plunger and the inner sleeve and the first leveling part of the piston cylinder to the push switch cover under the action of pressure. At the same time, during the descent of the piston cylinder, the air pressure inside the air-containing chamber increases, thereby pushing the second sealing part of the elastic sealing ring upward, and the high-pressure airflow enters the push switch cover from the gap between the inner sleeve and the second connecting part, mixes with the liquid, and forms a high-pressure spray that is sprayed out from the spray hole. When the hand force is released, the inner sleeve and the piston rod move upward under the action of the spring return elastic force until the conical plug of the column valve is separated from the conical hole, and the spherical plug is lifted up by the liquid level pressure of the upper liquid pipe, and the liquid inside the storage tank flows into the liquid chamber. At the same time, the piston cylinder is in the process of rising, and the air pressure inside the air chamber decreases, so that the external airflow pushes the first sealing part of the elastic sealing ring downward, allowing air to enter the air chamber again. In this cycle, the continuous pressing injection of the injector can be completed.

[0025] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
