Description

Technical Field

[0001] This utility model relates to a tear gas emission device. Background Technology

[0002] Current methods of breaking windows by personnel include using batons or flashlights with breaker tips to smash the glass. If it is necessary to control people inside, a separate tear gas launcher can be used to spray into the broken window. However, this method requires the cooperation of multiple people and equipment, has a long preparation time, and high coordination requirements, resulting in certain shortcomings in its use. To address this, a window-breaking tear gas device integrating a breaker tip and a tear gas canister has been developed. The squeeze spray tube of the tear gas canister is located on one side of the breaker tip. While breaking the window with the breaker tip, the tear gas canister is pressed from the bottom, compressing the squeeze spray tube and releasing the tear gas, thus reducing the time required for window breaking and control. However, because the squeeze spray tube of the tear gas canister requires considerable force to release the tear gas, if the operator is too tense or uses too much force during the window-breaking operation, the subsequent pressing of the squeeze spray tube may deform, preventing the proper release of the tear gas and affecting its effectiveness. This problem urgently needs to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a window-breaking tear gas sprayer that can quickly spray while breaking a window, making it easy to operate and more effective.

[0004] The technical solution of this utility model is: a window-breaking tear gas sprayer, including a shell with a breaking head on one side and a reservoir with a squeezing spray tube on one end. The reservoir is fitted inside the shell, the squeezing spray tube is located on one side of the breaking head, and the breaking head has a spray nozzle. It also includes a support base set on the other end of the shell, a hook part with a spring, a button part, and a protective cover set outside the support base. The support base has a stepped through hole. The bottom of the hook part is fitted on the other end of the reservoir and the upper part has a limiting groove, which extends from the stepped through hole to the protective cover. The spring is fitted on the hook part below the stepped through hole. The button part is horizontally slidably set inside the protective cover and has a buckle that cooperates with the limiting groove. When the buckle cooperates with the limiting groove, the spring generates elastic force between the support base and the reservoir.

[0005] The liquid storage tank is installed separately from the outer casing for easy replacement. The bottom of the hook is fitted onto the other end of the liquid storage tank, which can hold the tank in place and push it to move within the casing. The limiting groove on the upper part of the hook extends out of the support base and engages with the snap fastener on the button. This compresses the spring and creates elasticity between the support base and the liquid storage tank. When the button is pressed and slids horizontally, the snap fastener disengages from the limiting groove. Under the spring force, the hook pushes the liquid storage tank toward the side of the outer casing where the breaking head is located. This causes the squeezing spray pipe on the liquid storage tank to be squeezed, forming a spray that is then ejected from the spray nozzle. This transforms the spraying operation into a horizontal pressing motion, unlike the vertical movement of forcefully breaking the window. The pressing requires less pressure and avoids deformation caused by excessive window breaking that could affect the spraying operation, thus improving ease of operation. The window breaking and pressing spraying actions are highly coordinated.

[0006] A second spring is provided between the bottom of the button section and the inner wall of the protective cover. When the buckle engages with the limiting groove, the second spring generates elastic force between the bottom of the button section and the inner wall of the protective cover. The second spring can provide elastic force to keep the pressing part in a horizontal state, avoiding accidental activation of the pressing part during transportation or movement, thus preventing unnecessary spraying and improving the safety of the equipment.

[0007] The protective cover has an opening at the top. When the limiting groove at the top of the hook part engages with the snap fastener of the button part, the top of the hook part is located at the opening. This allows for direct observation of the hook part through the opening, confirming that the liquid storage bottle is installed in place and identifying whether the equipment is ready to spray.

[0008] The protective cover consists of a cylindrical body and an upper cover, with the opening located on the upper cover. The protective cover is a separate unit, facilitating the assembly of the button components.

[0009] A protective slider is provided on the cylindrical body to cover the button section. This effectively protects the button section from accidental activation.

[0010] The hook portion on the limiting groove has a sliding inclined surface that slopes inward from the outside, and the outer wall of the buckle has a guide inclined surface that cooperates with the sliding inclined surface. When the hook portion moves upward, the sliding inclined surface and the guide inclined surface can cooperate smoothly, thereby causing the button portion to compress the second spring and making the engagement between the buckle and the limiting groove more guiding and limiting, facilitating assembly.

[0011] The crushing head includes a housing and an alloy head at the top of the housing, with the housing movably connected to one end of the outer shell. This facilitates removal and replacement of the liquid storage tank inside the outer shell.

[0012] The housing of the breaking head has a hollow spray channel. The extrusion spray pipe of the liquid storage tank is located inside the spray channel. The spray nozzle is located on the housing of one side of the alloy head and is connected to the spray channel. The mist outlet is located on one side of the alloy head to facilitate the spraying of tear gas in the direction of force while breaking the window.

[0013] The housing on one side of the alloy head has six symmetrically arranged spray nozzles. The symmetrical arrangement of the spray nozzles facilitates the even distribution of the tear gas.

[0014] The outer wall of the casing is equipped with a non-slip grip. This improves the stability of the casing and facilitates window breaking operations.

[0015] The advantages of this invention are: it is easy to operate, it is easier to press and spray while breaking the window, the action is not easily deformed, and the effect is better. Attached Figure Description

[0021] See Figure 1-4A window-breaking tear gas sprayer includes a housing 1 with a breaking head 4 on one side and a reservoir 2 with a squeeze spray tube 3 on one end. The reservoir 2 is fitted inside the housing 1. The squeeze spray tube 3 is located on one side of the breaking head 4. The breaking head 4 has a spray nozzle 5. The sprayer also includes a support base 6 on the other end of the housing 1, a hook part 7 fitted with a spring 9, a button part 11, and a protective cover 10 on the outside of the support base 6. The support base 6 has a stepped through hole 23. The bottom of the hook part 7 is fitted on the other end of the reservoir 2. The upper part of the hook part 7 has a limiting groove 8, which extends from the stepped through hole 23 into the protective cover 10. The spring 9 is fitted on the hook part 7 below the stepped through hole 23. The button part 11 is horizontally slidably installed in the protective cover 10 and has a buckle 12 that cooperates with the limiting groove 8. When the buckle 12 cooperates with the limiting groove 8, the spring 9 generates elastic force between the support base 6 and the reservoir 2. In this embodiment, the support base 6 is threadedly connected to one end of the outer shell 1.

[0022] The liquid storage tank 2 is housed inside the outer casing 1 and is installed separately from the outer casing 1 for easy replacement. A sleeve 24 is provided at the bottom of the hook part 7, which is fitted onto one end of the liquid storage tank 2. The sleeve 24 and the liquid storage tank 2 can be interference-fitted to ensure the liquid storage tank 2 is securely fixed, reducing movement and ensuring that the liquid storage tank 2 can be precisely and effectively compressed. The limiting groove 8 at the upper part of the hook part 7 extends beyond the support base 6 and engages with the snap 12 of the button part 11, compressing the spring 9 and generating elastic force between the support base 6 and the liquid storage tank 2. When the button part 11 is pressed... Its horizontal sliding causes the buckle 12 to disengage from the limiting groove 8. Under the elastic force of the spring 9, the hook 7 pushes the liquid storage tank 2 toward the side of the outer shell 1 where the breaking head 4 is located. The squeezing spray pipe 3 on the liquid storage tank 2 is squeezed and begins to form a spray, which is then sprayed out from the spray nozzle 5. The horizontal pressing movement can produce a spray operation. Unlike the vertical movement direction of forcefully breaking the window, the pressure required for pressing is smaller. The action deformation caused by excessive window breaking will not affect the spray operation, thus making the operation more convenient. The action of breaking the window and pressing the spray has good continuity.

[0023] A second spring 13 is provided between the bottom of the button part 11 and the inner wall of the protective cover 10. When the buckle 12 engages with the limiting groove 8, the second spring 13 generates elastic force between the bottom of the button part 11 and the inner wall of the protective cover 10. The second spring 13 can provide elastic force to keep the pressing part 11 in a horizontal state, avoiding accidental activation of the pressing part during transportation or movement, thus preventing unnecessary spraying and improving the safety of the equipment.

[0024] The protective cover 10 has an opening 25 at its top. When the limiting groove 8 of the hook part 7 engages with the buckle 12 of the button part 11, the top of the hook part 7 is located at the opening 25. This allows the hook part 7 to be directly observed through the opening 25, thus confirming that the liquid storage tank 2 has been installed in place and identifying whether the equipment is in a ready-to-spray state.

[0025] The protective cover 10 consists of a cylindrical body 14 and an upper cover 15, with the opening 25 located on the upper cover 15. The protective cover is a separate unit, which facilitates the assembly of the button components.

[0026] A protective slider 16 is provided on the cylindrical body 14 to cover the button part 11. This can effectively protect the button part 11 from being accidentally activated.

[0027] The hook portion 7, located on the limiting groove 8, has a sliding inclined surface 17 that slopes inward from the outside. The outer wall of the buckle 12 has a guide inclined surface 18 that engages with the sliding inclined surface 17. When the hook portion 7 moves upward, the sliding inclined surface 17 and the guide inclined surface 18 can smoothly engage, thereby allowing the button portion 11 to compress the second spring 13 and making the engagement between the buckle 12 and the limiting groove 8 more directional and limiting, facilitating assembly.

[0028] The crushing head 4 includes a housing 19 and an alloy head 20 disposed on the top of the housing 19. The housing 19 is movably connected to one end of the outer casing 1, facilitating the removal and replacement of the liquid storage tank inside the outer casing.

[0029] The housing 19 of the breaking head 4 has a hollow spray channel 21. The extrusion spray pipe 3 of the liquid storage tank 2 is located inside the spray channel 21. The spray nozzle 5 is located on the housing 19 on one side of the alloy head 20 and is connected to the spray channel 21. The mist outlet 5 is located on one side of the alloy head 20 to facilitate the spraying of tear gas in the direction of force while breaking the window.

[0030] The housing 19 on one side of the alloy head 20 has six symmetrically arranged spray nozzles 5. The symmetrical arrangement of the spray nozzles facilitates the uniform distribution of the tear gas.

[0031] A non-slip grip 22 is provided on the outer wall of the outer casing 1. This improves the grip stability of the casing and facilitates window breaking operations.
