Description

Technical Field

[0001] The present invention relates to the field of liquid emitters, and more particularly to a liquid emitter and a combined liquid-emitting glass-breaking device containing the device. Background Art

[0002] In existing emitters, such as a bulletproof glass firing and breaking device for military, police, and fire protection disclosed by the applicant in application number CN202311361690.9, it includes an outer sleeve, a control unit, a motor, a transmission component, a firing component, and a columnar window-breaking rod. The motor, the transmission component, and the firing component are sequentially connected in transmission. The firing component includes an inner tube, a strong high-pressure spring sleeved inside the inner tube, and a positioning member connected to the outer end of the strong high-pressure spring. An ejection port is provided at one end of the inner tube facing away from the motor. An inner sliding port extending along the axial direction of the inner tube is provided on the side of the inner tube facing away from the motor. A clamping port that intersects and communicates with the inner sliding port is provided at the inner end of the inner sliding port. The outer end of the positioning member forms a top-against fit with the columnar window-breaking rod. Under normal conditions, the positioning member is clamped and fixed in the clamping port, and the strong high-pressure spring is in a compressed state. When the control unit starts the motor and the torque of the motor is transmitted to the firing component through the transmission component, the firing component causes the positioning member to instantly disengage from the clamping port and slide into the inner sliding port, and the strong high-pressure spring drives the columnar window-breaking rod to quickly eject outward to break the window.

[0003] This emitter needs to use a corresponding motor as a driving mechanism, the product structure is relatively complex and the cost is high, and due to the use of electronic devices, a good waterproof effect cannot be achieved. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a liquid emitter and a combined liquid-emitting glass-breaking device containing the device:

[0005] A liquid emitter, the liquid emitter comprises a first tube body, a piston switch, a piston head and a thrust spring, the outer end of the first tube body is detachably sealed and threadedly connected with a sealing head, a central injection hole is arranged in the middle of the sealing head, the first tube body is provided with a liquid storage cavity connected to the central injection hole, the liquid storage cavity, the piston head and the thrust spring are sequentially arranged in the first tube body, one end of the thrust spring is connected to a fixed spacer fixedly installed at the end of the first tube body cavity, and the other end of the thrust spring is connected to the piston head, the thrust spring is used to generate an elastic force on the piston head to squeeze the liquid storage cavity, the piston head and the liquid storage cavity form a piston match, the piston head is provided with an annular clamping groove on one side close to the thrust spring, the annular clamping groove and the piston switch form a clamping connection, the piston switch is used to control the fixation or movement of the piston head relative to the first tube body, under normal conditions, the piston switch locks the piston head, when the piston switch unlocks the piston head, the elastic force of the thrust spring on the piston head causes the piston head to squeeze the liquid storage cavity, so that the liquid in the liquid storage cavity is sprayed out from the central injection hole.

[0006] Preferably, a sealing ring is sleeved between the sealing head and the first tube body, and the sealing ring is used to improve the sealing between the sealing head and the first tube body. The sealing ring is integrally connected to a connecting strip, and the outer end of the connecting strip is integrally connected to a rubber plug. Under normal conditions, the rubber plug and the central injection hole form a plugging seal, and the rubber plug is used to prevent the liquid in the liquid storage chamber from leaking out. When the piston head squeezes the liquid storage chamber, the liquid in the liquid storage chamber breaks through the rubber plug and sprays outward. The rubber plug is fixedly connected to the sealing ring through the connecting strip to prevent the rubber plug from detaching from the launcher and shooting outward to hit the target's face or eyes and cause damage when the liquid is launched at high speed.

[0007] Preferably, the liquid storage chamber stores police tear gas liquid, capsaicin liquid or artificial synthetic irritant.

[0008] Preferably, the piston switch includes a rocker arm and a radial screw, the lower part of the rocker arm is provided with a through hole, the radial screw movably passes through the through hole and is threadedly connected with the threaded hole provided on the upper surface of the first tube body, one end of the rocker arm is provided with a hook portion, the hook portion passes through a locking opening provided on the upper surface of the first tube body and forms a locking fit with an annular locking groove of the piston head, the other end of the rocker arm is tilted upward relative to the first tube body, when the tilted end of the rocker arm is pressed downward, the rocker arm uses the contact point with the first tube body as a fulcrum to control the hook portion to disengage from the annular locking groove, at this time, the piston head squeezes the liquid in the liquid storage chamber under the elastic force of the thrust spring to spray out from the central injection hole.

[0009] Preferably, the piston switch further includes an arc-shaped elastic rod. The radial screw movably passes through through holes provided in both the lower portions of the rocker lever and the arc-shaped elastic rod. The arc-shaped elastic rod is disposed between the rocker lever and the first tube body. The middle portion of the arc-shaped elastic rod protrudes toward one side of the first tube body and abuts against the surface of the first tube body. When the raised end of the rocker lever is forced downward, the rocker lever uses the contact point between the arc-shaped elastic rod and the first tube body as a fulcrum to control the hook portion to disengage from the annular clamping groove. At this time, the piston head squeezes the liquid in the liquid storage cavity under the elastic force of the thrust spring and sprays it out from the central ejection hole.

[0010] Preferably, the liquid emitter further includes an anti-misoperation protection sliding sleeve that movably sleevs the first tube body. The upper portion of the anti-misoperation protection sliding sleeve is provided with an open sliding cavity adapted to the rocker lever. When the rocker lever is located in the open sliding cavity, the anti-misoperation protection sliding sleeve covers the rocker lever to prevent external force on the rocker lever. When the rocker lever slides out of the open sliding cavity, the rocker lever is exposed outside.

[0011] Preferably, the liquid emitter further includes a clamping hoop fixedly sleeved outside the first tube body. A laser sight is installed at the bottom of the clamping hoop. The clamping hoop is located on one side of the anti-misoperation protection sliding sleeve closer to the outer end of the first tube body. The clamping hoop and the anti-misoperation protection sliding sleeve form a limit fit. A switch portion corresponding to the laser sight is provided at the lower portion of the anti-misoperation protection sliding sleeve. When the anti-misoperation protection sliding sleeve slides toward the clamping hoop side, the rocker lever is exposed outside and the switch portion is adapted to the laser sight to control the activation of the laser sight.

[0012] Preferably, one end of the laser sight is fixedly connected to the bottom of the clamping hoop. An outwardly protruding sliding switch is provided on the lower end surface of the laser sight. The switch portion is a U-shaped sleeve portion. A square through cavity adapted to the laser sight is provided inside the U-shaped sleeve portion. When the anti-misoperation protection sliding sleeve slides relative to the clamping hoop side, the laser sight slides into the square through cavity. At this time, the U-shaped sleeve portion contacts and toggles the sliding switch to activate the laser sight.

[0013] Preferably, a columnar protrusion is provided on the bottom of the anti-misoperation protection sliding sleeve. A columnar cavity is provided inside the columnar protrusion. A ball screw is threadedly connected inside the columnar cavity. The ball screw includes a damping steel ball and a damping spring. The damping steel ball forms an elastic abutment fit with the lower surface of the first tube body. The damping spring is used to generate an elastic force on the damping steel ball to make it elastically abut against the lower surface of the first tube body. The ball screw provides a corresponding damping force for the sliding of the anti-misoperation protection sliding sleeve to prevent the anti-misoperation protection sliding sleeve from sliding easily. The user can control the damping between the ball screw and the first tube body by controlling the depth of the ball screw in the columnar cavity.

[0014] A combined liquid - fired glass - breaking device includes a first tube assembly and a second tube assembly. The first tube assembly is the liquid emitter, and the second tube assembly is the glass - breaking device or the liquid emitter. Both the first tube assembly and the second tube assembly are in a tubular structure, and the relative inner ends of the first tube assembly and the second tube assembly are detachably connected in series. In this application, through detachable series - connection methods such as threaded connection or snap - connection, the combined installation of the liquid emitter and the glass - breaker can be realized, or two liquid emitters can be detachably connected to each other, achieving a corresponding flexible combined installation method.

[0015] Preferably, it further includes an intermediate connector. The intermediate connector includes an intermediate tube body part and two threaded connection ends integrally located at both ends of the intermediate tube body part respectively. The outer diameter sizes of the intermediate tube body part, the first tube assembly, and the second tube assembly are the same, and the two threaded connection ends respectively form a detachable threaded connection with the first tube assembly and the second tube assembly.

[0016] Beneficial effects: In the liquid emitter of this application, a ring - shaped clamping groove provided on the piston head forms a clamping connection with the piston switch. The user unlocks or locks the piston head through the piston switch. Under normal conditions, the piston switch locks the piston head. When the piston switch unlocks the piston head, the elastic force of the thrust spring on the piston head causes the piston head to squeeze the liquid storage cavity, so that the liquid in the liquid storage cavity sprays out from the central spray hole. This product adopts a pure mechanical structure, which is simple and easy to produce and promote, and does not require any electronic devices. Therefore, the cost is low and it has a good waterproof and durable effect. In addition, the product does not require any high - pressure air cavity structure, and the safety factor is high.

Detailed implementation mode

[0025] The following combines the attached Figures 1-7 This invention will be further described in combination with Examples 1-2.

[0026] Example 1: As Figures 1-5 shown, when traffic police and policemen conduct routine inspections on passing vehicles on the road surface, when the vehicle being inspected refuses to open the door and lower the window for inspection, and still does not open the door and lower the window after three warnings, the policemen can legally break the window of the vehicle by force and effectively control the driver of the illegal vehicle. However, most of the window glasses of current fuel vehicles and new energy electric vehicles are double-layer laminated glasses, which are very firm! Conventional window breakers can only break single-layer window tempered glasses, and they simply cannot break double-layer laminated glasses. If a special window-breaking hammer is used, it also takes a long time to break, and the window-breaking hammer is large and heavy, making it inconvenient for policemen to carry. Therefore, according to the above requirements for the law enforcement equipment of traffic police and policemen, our company has developed a portable, one-second double-layer laminated glass window-breaking, and can quickly conduct tear gas spraying on the people in the vehicle who still do not get out of the vehicle for inspection after the policemen legally break the window, forcing the illegal people in the vehicle to be unable to bear the stimulation of tear gas and making them quickly get out of the vehicle for inspection, a powerful window-breaking and tear gas-emitting integrated police equipment.

[0027] A combined liquid-emitting window-breaking device includes a first pipe assembly 1 and a second pipe assembly 2. The first pipe assembly 1 is a liquid emitter, and the second pipe assembly 2 is a window-breaking device. Both the first pipe assembly 1 and the second pipe assembly 2 are in a tubular structure, and the relative inner ends of the first pipe assembly 1 and the second pipe assembly 2 are detachably threaded in series. The window-breaking device described in this application adopts a portable mechanical window breaker disclosed in the application number 2020214933151 applied by the applicant on July 24, 2020. By setting corresponding threaded protrusion ends at the ends of the portable mechanical window breaker, the corresponding detachable threaded connection effect can be achieved.

[0028] The liquid emitter includes a first tube body 29, a piston switch, a piston head 3 and a thrust spring 4. The outer end of the first tube body 29 is detachably and hermetically threadedly connected with a sealing head 5. A central injection hole 6 is provided in the middle of the sealing head 5. A liquid storage cavity 25 communicating with the central injection hole 6 is provided in the first tube body 29. The liquid storage cavity 25, the piston head 3 and the thrust spring 4 are sequentially arranged in the first tube body 29. One end of the thrust spring 4 is connected to a fixed partition 7 fixedly installed at the inner end of the cavity of the first tube body 29, and the other end of the thrust spring 4 is connected to the piston head 3. The thrust spring 4 is used to generate an elastic force on the piston head 3 to make it extrude the liquid storage cavity 25. The piston head 3 and the liquid storage cavity 25 form a piston fit. The liquid storage cavity 25 stores police tear gas liquid, capsaicin liquid or synthetic irritant. An annular clamping groove 8 is provided on the side of the piston head 3 close to the thrust spring 4. The annular clamping groove 8 is in clamping connection with the piston switch. The piston switch is used to control the fixation or movement of the piston head 3 relative to the first tube body 29. Under normal conditions, the piston switch locks the piston head 3. When the piston switch unlocks the piston head 3, the elastic force of the thrust spring 4 on the piston head 3 causes the piston head 3 to extrude the liquid storage cavity 25, so that the liquid in the liquid storage cavity 25 is ejected from the central injection hole 6.

[0029] As Figure 4 shown, a sealing ring 26 is sleeved between the sealing head 5 and the first tube body 29. The sealing ring 26 is used to improve the sealing performance between the sealing head 5 and the first tube body 29. The sealing ring 26 is integrally connected with a connecting strip 27. The outer end of the connecting strip 27 is integrally connected with a rubber plug 28. Under normal conditions, the rubber plug 28 is in plugging and sealing cooperation with the central injection hole 6. The rubber plug 28 is used to prevent the liquid in the liquid storage cavity 25 from leaking. When the piston head 3 extrudes the liquid storage cavity 25, the liquid in the liquid storage cavity 25 breaks through the rubber plug 28 and sprays outwards.

[0030] As Figure 4As shown, the piston switch includes a rocker 9, an arc-shaped elastic rod 10 and a radial screw 11. The lower parts of the rocker 9 and the arc-shaped elastic rod 10 are both provided with a through hole. The radial screw 11 movably passes through the through hole and is threadedly connected with the threaded hole provided on the upper surface of the first tube body 29. One end of the rocker 9 is provided with a hook portion 12. The hook portion 12 passes through the locking opening provided on the upper surface of the first tube body 29 to form a locking fit with the annular locking groove 8 of the piston head 3. The other end of the rocker 9 is relative to the first tube body 29. The body 29 is tilted upward, and the arc-shaped elastic rod 10 is arranged between the rocker 9 and the first tube body 29. The middle part of the arc-shaped elastic rod 10 is convex relative to one side of the first tube body 29 and abuts against the surface of the first tube body 29. When the tilted end of the rocker 9 is pressed downward, the rocker 9 uses the contact point between the arc-shaped elastic rod 10 and the first tube body 29 as a fulcrum to control the hook portion 12 to disengage from the annular locking groove 8. At this time, the piston head 3 squeezes the liquid in the liquid storage chamber 25 under the elastic force of the thrust spring 4 to spray out from the central injection hole 6.

[0031] The liquid emitter further comprises an anti-misoperation protection sliding sleeve 13 movably sleeved on the first tube body 29 and a clamping hoop 15 fixedly sleeved on the outside of the first tube body 29. An open sliding cavity 14 adapted to the rocker 9 is provided on the upper portion of the anti-misoperation protection sliding sleeve 13. When the rocker 9 is located in the open sliding cavity 14, the anti-misoperation protection sliding sleeve 13 covers the rocker 9 to prevent the rocker 9 from being subjected to external force. When the rocker 9 slides out of the open sliding cavity 14, the rocker 9 is exposed to the outside. A laser sight 16 is installed at the bottom of the locking hoop 15. The locking hoop 15 is close to the outer end of the first tube body 29 relative to the anti-maloperation protection sleeve 13. The locking hoop 15 and the anti-maloperation protection sleeve 13 form a limiting fit. The lower part of the anti-maloperation protection sleeve 13 is provided with a switch part corresponding to the laser sight 16. When the anti-maloperation protection sleeve 13 slides toward the side of the locking hoop 15, the rocker 9 is exposed and the switch part adapts to the laser sight 16 to control the start of the laser sight 16. The bottom of the anti-maloperation protection sleeve 13 is provided with a cylindrical protrusion 19 protruding outward, and a cylindrical cavity is provided in the cylindrical protrusion 19. A ball screw is threadedly connected in the cylindrical cavity. The ball screw includes a damping steel ball 20 and a damping spring 21. The damping steel ball 20 is elastically abutted against the lower surface of the first tube body 29. The damping spring 21 is used to generate an elastic force on the damping steel ball 20 to elastically abut against the lower surface of the first tube body 29. The ball screw provides a corresponding damping force for the sliding of the anti-maloperation protection sleeve 13 to prevent the anti-maloperation protection sleeve 13 from sliding easily.

[0032] One end of the laser sight 16 is fixedly connected to the bottom of the clamping hoop 15. A sliding switch 17 protruding outward is provided on the lower end surface of the laser sight 16. The switch part is a U-shaped sleeve part 18. The U-shaped sleeve part 18 is internally provided with a square through cavity adapted to the laser sight 16. When the anti-misoperation protection sliding sleeve 13 slides relative to one side of the clamping hoop 15, the laser sight 16 slides into the square through cavity. At this time, the U-shaped sleeve part 18 contacts and toggles the sliding switch 17, thereby starting the laser sight 16. The laser sight 16 described in this application is directly purchased from the existing market, so it will not be elaborated too much.

[0033] Embodiment 2: As Figures 6-7 shown, a combined liquid-actuated glass-breaking device includes a first pipe assembly 1, a second pipe assembly 2, and an intermediate connector 22. Both the first pipe assembly 1 and the second pipe assembly 2 are liquid emitters. The relative inner ends of the first pipe assembly 1 and the second pipe assembly 2 are detachably connected in series by threads. The intermediate connector 22 includes an intermediate pipe body part 23 and two threaded connection ends 24 integrally located at both ends of the intermediate pipe body part 23 respectively. The intermediate pipe body part 23, the first pipe assembly 1, and the second pipe assembly 2 are pipe-shaped structures with the same outer diameter dimension. The two threaded connection ends 24 respectively form a detachable threaded connection with the first pipe assembly 1 and the second pipe assembly 2.

[0034] The liquid emitter includes a first pipe body 29, a piston switch, a piston head 3, and a thrust spring 4. The outer end of the first pipe body 29 is detachably and sealingly connected by threads with a sealing head 5. A central injection hole 6 is provided in the middle of the sealing head 5. A liquid storage cavity 25 communicating with the central injection hole 6 is provided in the first pipe body 29. The liquid storage cavity 25, the piston head 3, and the thrust spring 4 are sequentially arranged in the first pipe body 29. One end of the thrust spring 4 is connected to a fixed spacer 7 fixedly installed at the inner end of the cavity of the first pipe body 29. The other end of the thrust spring 4 is connected to the piston head 3. The thrust spring 4 is used to generate an elastic force on the piston head 3 to make it extrude the liquid storage cavity 25. The piston head 3 and the liquid storage cavity 25 form a piston fit. The liquid storage cavity 25 stores police tear gas liquid, capsaicin liquid, or synthetic irritant. An annular clamping groove 8 is provided on the side of the piston head 3 close to the thrust spring 4. The annular clamping groove 8 forms a clamping connection with the piston switch. The piston switch is used to control the fixation or movement of the piston head 3 relative to the first pipe body 29. Under normal conditions, the piston switch locks the piston head 3. When the piston switch unlocks the piston head 3, the elastic force of the thrust spring 4 on the piston head 3 makes the piston head 3 extrude the liquid storage cavity 25, so that the liquid in the liquid storage cavity 25 is ejected from the central injection hole 6.

[0035] A sealing ring 26 is sleeved between the sealing head 5 and the first tube body 29. The sealing ring 26 is used to improve the sealing between the sealing head 5 and the first tube body 29. The sealing ring 26 is integrally connected to a connecting strip 27. The outer end of the connecting strip 27 is integrally connected to a rubber plug 28. Under normal circumstances, the rubber plug 28 and the central injection hole 6 form a plugging seal. The rubber plug 28 is used to prevent the liquid in the liquid storage chamber 25 from leaking out. When the piston head 3 squeezes the liquid storage chamber 25, the liquid in the liquid storage chamber 25 breaks through the rubber plug 28 and is sprayed outward.

[0036] The piston switch comprises a rocker 9, an arcuate elastic rod 10 and a radial screw 11. The lower parts of the rocker 9 and the arcuate elastic rod 10 are both provided with a through hole. The radial screw 11 movably passes through the through hole and is threadedly connected with the threaded hole provided on the upper surface of the first tube body 29. One end of the rocker 9 is provided with a hook portion 12. The hook portion 12 passes through the locking opening provided on the upper surface of the first tube body 29 to form a locking fit with the annular locking groove 8 of the piston head 3. The other end of the rocker 9 is opposite to the first tube body 2 9 is tilted upward, and the arc-shaped elastic rod 10 is arranged between the rocker 9 and the first tube body 29. The middle part of the arc-shaped elastic rod 10 is convex relative to one side of the first tube body 29 and abuts against the surface of the first tube body 29. When the tilted end of the rocker 9 is pressed downward, the rocker 9 uses the contact point between the arc-shaped elastic rod 10 and the first tube body 29 as a fulcrum to control the hook portion 12 to disengage from the annular locking groove 8. At this time, the piston head 3 squeezes the liquid in the liquid storage chamber 25 under the elastic force of the thrust spring 4 to spray out from the central injection hole 6.

[0037] The liquid emitter further includes an anti-misoperation protection sliding sleeve 13 movably sleeved on the first pipe body 29 and a clamping hoop 15 fixedly sleeved outside the first pipe body 29. An opening sliding cavity 14 adapted to the rocker 9 is provided in the upper part of the anti-misoperation protection sliding sleeve 13. When the rocker 9 is located in the opening sliding cavity 14, the anti-misoperation protection sliding sleeve 13 covers the rocker 9 to prevent external force on the rocker 9. When the rocker 9 slides out of the opening sliding cavity 14, the rocker 9 is exposed outside. A laser sight 16 is installed at the bottom of the clamping hoop 15. The clamping hoop 15 is relatively closer to the outer end of the first pipe body 29 than the anti-misoperation protection sliding sleeve 13. The clamping hoop 15 and the anti-misoperation protection sliding sleeve 13 form a limit fit. A switch part corresponding to the laser sight 16 is provided in the lower part of the anti-misoperation protection sliding sleeve 13. When the anti-misoperation protection sliding sleeve 13 slides towards the clamping hoop 15, the rocker 9 is exposed outside and the switch part is adapted to the laser sight 16 to control the activation of the laser sight 16. A cylindrical protrusion 19 protruding outwards is provided at the bottom of the anti-misoperation protection sliding sleeve 13. A cylindrical cavity is provided in the cylindrical protrusion 19. A ball screw is threadedly connected in the cylindrical cavity. The ball screw includes a damping steel ball 20 and a damping spring 21. The damping steel ball 20 is elastically abutted and adapted to the lower surface of the first pipe body 29. The damping spring 21 is used to generate an elastic acting force on the damping steel ball 20 to elastically abut it against the lower surface of the first pipe body 29. The ball screw provides a corresponding damping acting force for the sliding of the anti-misoperation protection sliding sleeve 13 to prevent the anti-misoperation protection sliding sleeve 13 from sliding easily.

[0038] One end of the laser sight 16 is fixedly connected to the bottom of the clamping hoop 15. An outwardly protruding sliding switch 17 is provided on the lower end surface of the laser sight 16. The switch part is a U-shaped sleeve part 18. A square through cavity adapted to the laser sight 16 is provided inside the U-shaped sleeve part 18. When the anti-misoperation protection sliding sleeve 13 slides relative to the clamping hoop 15, the laser sight 16 slides into the square through cavity. At this time, the U-shaped sleeve part 18 contacts and toggles the sliding switch 17 to activate the laser sight 16. The laser sight 16 described in this application is directly purchased from the existing market, so it will not be elaborated too much. As Figures 6-7 shown, a chamfer part is provided at the lower part of the end of the U-shaped sleeve part 18 facing away from the laser sight 16. The chamfer part is used to prevent the sharp corner area from touching the user's hand and improve the user experience.
