Description

Technical Field

[0001] This utility model relates to the field of police equipment technology, specifically a Bluetooth anti-theft system for police high-speed tear gas devices. Background Technology

[0002] The electric-activated high-speed tear gas canister is a police device used to subdue criminals and maintain public safety. It uses electricity to launch tear gas at high speed at the criminal, temporarily incapacitating them and allowing for their subjugation. While practical, the electric-activated tear gas canister has several drawbacks. For example, it is easily stolen, causing serious problems and increasing public harm. Furthermore, current tear gas canisters lack positioning capabilities and cannot be used to limit their range of use via BeiDou navigation. Criminals can steal the canister and its holster or body, allowing them to use it in other locations, posing a significant threat to public safety. Therefore, this invention proposes a Bluetooth anti-theft system for the electric high-speed tear gas canister to address these issues. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a Bluetooth anti-theft system for police high-speed tear gas canisters. By installing a first Bluetooth module inside the holster and a second Bluetooth module on a circuit board inside the tear gas canister, the two modules are wirelessly connected. When the tear gas canister is moved away from the holster, the Bluetooth signal connection is disconnected, thereby disconnecting the circuit switch and preventing the tear gas pressurizing pump inside the canister from functioning properly. This achieves the purpose of anti-theft, rendering the canister unusable even after theft. This solves the current problem of tear gas canisters being easily stolen, thus increasing the risk of harm.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A Bluetooth anti-theft system for police high-speed tear gas canisters includes a tear gas canister body and a holster, and further includes: a first Bluetooth module mounted on the holster; a second Bluetooth module mounted on a circuit board inside the tear gas canister body, with the first and second Bluetooth modules connected via short-range wireless signals; a circuit switch and a tear gas pressurized water pump, both mounted inside the tear gas canister body. The output of the second Bluetooth module is electrically connected to the input of the circuit switch, and the circuit switch and the tear gas pressurized water pump are connected in series. When the tear gas canister body is close to the holster, the circuit switch is activated via the wireless connection between the first and second Bluetooth modules, thereby activating the power supply circuit of the tear gas pressurized water pump, enabling the water pump to function normally. When the tear gas canister body and the holster are far apart, the water pump cannot function normally, thus achieving the purpose of preventing the theft of the tear gas canister body.

[0008] Furthermore, the first Bluetooth module and the second Bluetooth module transmit wirelessly over a short distance of 10m. When the distance between the tear gas gun body and the holster exceeds 10m, the second Bluetooth module on the circuit board cannot receive the wireless signal, and thus disconnects the circuit switch, causing the tear gas pressurizing pump to stop working.

[0009] Furthermore, a first power module is installed inside the holster, and the first power module is connected in series with a first Bluetooth module.

[0010] Furthermore, a second power module is installed inside the tear gas gun body to power the second Bluetooth module and the tear gas pressurizing water pump. A power monitoring unit for monitoring the power level of the second power module is installed inside the tear gas gun body. The power monitoring unit includes: a voltage detection module electrically connected to the positive circuit of the second power module; a controller installed inside the tear gas gun body, with the output terminal of the voltage detection module electrically connected to the input terminal of the controller; and a warning module including a buzzer and an indicator light installed on the outer shell of the tear gas gun body, with the output terminal of the controller electrically connected to the input terminals of the buzzer and the indicator light, respectively.

[0011] Furthermore, a tear gas control switch is installed at the handle of the tear gas gun body, and the tear gas control switch is connected in series with the tear gas pressurization water pump.

[0012] Furthermore, the tear gas gun body is equipped with a pepper spray storage box, which is connected to the inlet port of the tear gas pressurized water pump, and the tear gas gun body is equipped with a liquid outlet, through which the pepper spray discharged by the tear gas pressurized water pump can be sprayed out.

[0013] Furthermore, it also includes a Beidou positioning control unit installed inside the tear gas canister gun body. The Beidou positioning control unit includes: a Beidou positioning module fixed inside the tear gas canister gun body; a 4G IoT card installed inside the tear gas canister gun body, the Beidou positioning module being connected to a first Bluetooth module on the holster via the 4G IoT card for bidirectional wireless connection; a storage module installed inside the tear gas canister gun body, with the output of the Beidou positioning module electrically connected to the input of the storage module, the storage module being able to store the trajectory information of the tear gas canister gun body according to the Beidou positioning module, thereby realizing the positioning and retrieval of the tear gas canister gun body; a relay and a processor, both installed inside the tear gas canister gun body, the output of the Beidou positioning module being electrically connected to the input of the processor, the relay being installed on the power supply circuit of the tear gas canister gun body, the Beidou positioning module realizing real-time monitoring of the position information of the tear gas canister gun body, when the real-time position of the tear gas canister gun body exceeds the distance range set by the processor, the processor controls the relay, thereby disconnecting the second power module, so that the tear gas canister gun body cannot work.

[0014] Furthermore, it also includes a terminal device, which is a smartphone with map software downloaded on it. The Beidou positioning module is wirelessly connected to the terminal device via a 4G IoT card, and the location information of the tear gas gun can be viewed in real time on the terminal device through the Beidou positioning module.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a Bluetooth anti-theft system for police high-speed tear gas devices, which has the following beneficial effects:

[0017] 1. This utility model involves installing a first Bluetooth module inside the holster and a second Bluetooth module on the circuit board inside the tear gas canister. The first and second Bluetooth modules transmit wireless signals over a short distance of ten meters. When the tear gas canister is close to the holster, the circuit switch is activated through the second Bluetooth module, ensuring the operation of the tear gas pressurizing pump. When in use, pulling the tear gas control switch causes the pressurizing pump to draw water from the pepper spray storage box, achieving tear gas control. When criminals steal or snatch the tear gas canister, the canister is moved away from the holster, disconnecting the signal between the two Bluetooth modules and thus disconnecting the circuit switch. This prevents the pressurizing pump from functioning properly, rendering the tear gas canister unusable. Therefore, even if criminals steal the tear gas canister, they cannot use it, preventing harm to society. This achieves the purpose of theft prevention and security, ensuring the normal use of the tear gas canister.

[0018] 2. This utility model, by installing a Beidou positioning control unit on the tear gas gun body, mainly consists of a Beidou positioning module, a storage module, a processor, and a relay. The Beidou positioning module can locate the tear gas gun body's position information in real time and feed this information back to the terminal device, enabling real-time monitoring. When criminals steal the tear gas gun body or holster, it can only be used within a limited area. Therefore, police officers can quickly locate the criminals and the tear gas based on the positioning information. When criminals move the tear gas gun body or holster outside the designated area, the Beidou positioning module detects the real-time position of the tear gas gun body, and the processor controls the relay to operate. The relay disconnects the power supply circuit of the tear gas gun body, preventing it from working properly. Therefore, when criminals move the tear gas gun body outside the designated area, it cannot be used, ensuring the security of the device. The Beidou positioning module is wirelessly connected to the terminal device via a 4G IoT card, enabling real-time monitoring of the tear gas gun body's position information.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 As shown in the figure, an embodiment of this utility model proposes a Bluetooth anti-theft system for police high-speed tear gas canisters, including a tear gas canister body 1 and a holster 2, and further including: a first Bluetooth module 3, installed on the holster 2; a second Bluetooth module 5, installed on a circuit board inside the tear gas canister body 1, and the first Bluetooth module 3 and the second Bluetooth module 5 are connected by a short-range wireless signal; a circuit switch 6 and a tear gas pressurizing water pump 7, both of which are installed inside the tear gas canister body 1; and the second Bluetooth module... The output terminal of 5 is electrically connected to the input terminal of the circuit switch 6, and the circuit switch 6 is connected in series with the tear gas pressurized water pump 7. When the tear gas gun body 1 is close to the gun holster 2, the circuit switch 6 can be turned on through the wireless connection between the first Bluetooth module 3 and the second Bluetooth module 5, thereby turning on the power supply circuit of the tear gas pressurized water pump 7, so that the tear gas pressurized water pump 7 can be used normally. When the tear gas gun body 1 and the gun holster 2 are far apart, the tear gas pressurized water pump 7 cannot work normally, thereby achieving the purpose of anti-theft of the tear gas gun body 1.

[0026] It should be noted that the tear gas gun body 1 is the main part of the police tear gas device. By installing a first Bluetooth module 3 inside the holster 2 and a second Bluetooth module 5 on the circuit board inside the tear gas gun body 1, the first Bluetooth module 3 and the second Bluetooth module 5 can establish a short-range wireless signal connection. The second Bluetooth module 5 can control the working state of the circuit switch 6. When the distance between the tear gas gun body 1 and the holster 2 is close, the circuit switch 6 can be turned on through the second Bluetooth module 5, thereby enabling the tear gas pressurizing pump 7 to work normally and allowing the tear gas gun body 1 to be used normally. When the tear gas gun body 1 is far away from the holster 2, the first Bluetooth module 3 and the second Bluetooth module 5 are out of the signal connection range, and the circuit switch 6 is automatically disconnected, preventing the tear gas pressurizing pump 7 from working normally, and thus rendering the tear gas gun body 1 unusable. This method can prevent criminals from stealing the tear gas gun body 1 and thus increasing social harm.

[0027] like Figure 1 As shown, in some embodiments, the first Bluetooth module 3 and the second Bluetooth module 5 transmit wirelessly over a short distance of 10m. When the distance between the tear gas gun body 1 and the gun holster 2 exceeds 10m, the second Bluetooth module 5 on the circuit board cannot receive the wireless signal, and then disconnects the circuit switch 6, causing the tear gas pressurizing water pump 7 to stop working.

[0028] It should be noted that 10m is a safe distance. If criminals steal the tear gas gun body 1 and the distance exceeds 10m, the tear gas gun body 1 will not be able to be used normally.

[0029] like Figure 1As shown, in some embodiments, a first power module 4 is installed inside the holster 2, and the first power module 4 is connected in series with the first Bluetooth module 3.

[0030] It should be noted that the first power module 4 enables the first Bluetooth module 3 to be powered, ensuring that the first Bluetooth module 3 remains in normal condition in real time.

[0031] like Figure 1 As shown, in some embodiments, a second power module 9 is installed inside the tear gas gun body 1 to provide power to the second Bluetooth module 5 and the tear gas pressurizing water pump 7. A power monitoring unit 12 for monitoring the power level of the second power module 9 is installed inside the tear gas gun body 1. The power monitoring unit 12 includes: a voltage detection module 1201 electrically connected to the positive circuit of the second power module 9; a controller 1202 installed inside the tear gas gun body 1, with the output terminal of the voltage detection module 1201 electrically connected to the input terminal of the controller 1202; and a warning module 1203 including a buzzer 1204 and an indicator light 1205 installed on the outer shell of the tear gas gun body 1, with the output terminal of the controller 1202 electrically connected to the input terminals of the buzzer 1204 and the indicator light 1205, respectively.

[0032] It should be noted that the second power module 9 is a rechargeable lithium battery, which can power the second Bluetooth module 5 and the tear gas pressurized water pump 7. The power monitoring unit 12 can monitor the real-time power of the second power module 9. When the power is too low, it can issue a warning message to ensure the normal use of the equipment. The power monitoring unit 12 mainly consists of a voltage detection module 1201, a controller 1202 and an early warning module 1203. The early warning module 1203 consists of a buzzer 1204 and an indicator light 1205. The voltage detection module 1201 can realize the real-time monitoring of the power of the second power module 9. When the power of the second power module 9 is too low, it can make the buzzer 1204 and the indicator light 1205 work to serve as a warning. The second power module 9 can be recharged and used repeatedly, and has good economic and environmental performance.

[0033] like Figure 1 As shown, in some embodiments, a tear gas control switch 11 is installed at the handle of the tear gas gun body 1, and the tear gas control switch 11 is connected in series with the tear gas pressurization water pump 7.

[0034] It should be noted that when the tear gas gun body 1 is close to the holster 2, the tear gas pressurizing water pump 7 is working normally. At this time, the tear gas pressurizing water pump 7 can be controlled by the tear gas control switch 11 to spray pepper spray.

[0035] like Figure 1As shown, in some embodiments, a pepper spray storage box 10 is provided inside the tear gas gun body 1. The pepper spray storage box 10 is connected to the water inlet port of the tear gas pressurized water pump 7, and a liquid outlet 8 is provided on the tear gas gun body 1. The pepper spray discharged by the tear gas pressurized water pump 7 can be sprayed out through the liquid outlet 8.

[0036] It should be noted that the pepper spray storage box 10 is located inside the tear gas gun body 1 and is used to store pepper spray. In actual use, a hose can be connected to the tear gas pressurizing pump 7 and inserted into the pepper spray storage box 10 to supply the tear gas pressurizing pump 7 with the pepper spray. This allows the tear gas pressurizing pump 7 to emit pepper spray, which can then be sprayed out through the outlet 8, enabling the normal use of the tear gas gun body 1.

[0037] Example 2

[0038] like Figure 1 and Figure 3 As shown, a Bluetooth anti-theft system for police high-speed tear gas devices also includes a Beidou positioning control unit 13 installed inside the tear gas gun body 1. The Beidou positioning control unit 13 includes: a Beidou positioning module 1301, fixed inside the tear gas gun body 1; a 4G IoT card 1302, installed inside the tear gas gun body 1, the Beidou positioning module 1301 and the first Bluetooth module 3 on the holster 2 being connected wirelessly in both directions via the 4G IoT card 1302; and a storage module 1303, installed inside the tear gas gun body 1, with the output terminal of the Beidou positioning module 1301 electrically connected to the input terminal of the storage module 1303, the storage module 1303 being able to adjust the positioning based on the Beidou positioning module's input. 1301 stores the trajectory information of the tear gas gun body 1, thereby enabling the positioning and retrieval of the tear gas gun body 1; relay 1304 and processor 1305 are both installed inside the tear gas gun body 1. The output terminal of the Beidou positioning module 1301 is electrically connected to the input terminal of the processor 1305. Relay 1304 is installed on the power supply circuit of the tear gas gun body 1. Beidou positioning module 1301 realizes real-time monitoring of the position information of tear gas gun body 1. When the real-time position of tear gas gun body 1 exceeds the distance range set by processor 1305, processor 1305 controls relay 1304, thereby disconnecting the second power module 9, so that tear gas gun body 1 cannot work.

[0039] like Figure 1 and Figure 3 As shown, in some embodiments, a terminal device 14 is also included. The terminal device 14 is a smartphone with map software downloaded on it. The Beidou positioning module 1301 is wirelessly connected to the terminal device 14 through a 4G IoT card 1302. Then, the location information of the tear gas gun body 1 can be viewed in real time on the terminal device 14 through the Beidou positioning module 1301.

[0040] It should be noted that the Beidou positioning control unit 13 is installed inside the tear gas canister gun body 1, enabling real-time monitoring of the tear gas canister gun body 1's location information and controlling its working status based on the location information. When the tear gas canister gun body 1 exceeds the predetermined position, it will not function properly, preventing criminals from stealing the tear gas canister gun body 1 and holster 2 and transporting it to other locations for use. This greatly ensures the safety of the equipment; even if the tear gas canister gun body 1 and holster 2 are stolen, they cannot be used normally, demonstrating its anti-theft feature. The Beidou positioning module 1301 can monitor the location information of the tear gas canister gun body 1 and transmit the location data via the 4G IoT card 1302. The information is transmitted to the terminal device 14 and the gun holster 2, enabling remote monitoring. The location information of the tear gas gun body 1 can be viewed through a smartphone. At the same time, the Beidou positioning module 1301 can store the trajectory information of the tear gas gun body 1 in the storage module 1303, thereby realizing the monitoring of the location trajectory of the tear gas gun body 1 and facilitating the retrieval of the device. The relay 1304 is installed on the power supply circuit of the tear gas gun body 1. When the tear gas gun body 1 exceeds the preset range, the processor 1305 controls the relay 1304 to disconnect the power supply circuit of the second power module 9, so that the tear gas gun body 1 cannot work, thereby realizing the anti-theft protection of the tear gas gun body 1 and the gun holster 2.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
