[0028] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The following will describe the embodiments of the present utility model in conjunction with the accompanying drawings.

[0029] like Figure 1 , Figure 2As shown, a drug launcher comprises a launcher body 1 and a launch tube 3 capable of loading ammunition 2, wherein the launcher body 1 is provided with a launch port 10, the launch tube 3 is a hollow tube, the launch tube 3 can be inserted into the launcher body 1 from the launch port 10 and is detachably connected, and the ammunition 2 contains medicine; a battery 4, an air storage chamber 5 and a pneumatic cavity 6 are arranged inside the launcher body 1, the air inlet of the pneumatic cavity 6 is connected to an inflation tube 7, the two air outlets of the pneumatic cavity 6 are respectively connected to the launch tube 3 and the air storage chamber 5, the inflation tube 7 can be externally connected to an inflation pump for filling the air storage chamber 5 with compressed air; an air flow conversion mechanism is arranged inside the pneumatic cavity 6, the air flow conversion mechanism is connected to a launch switch 8, and the launch switch 8 is used to control the air flow conversion mechanism to change the direction of the air flow in the pneumatic cavity 6; the air flow conversion mechanism and the launch switch 8 are both connected to the battery 4. A high-pressure compressed gas is injected into the gas storage chamber 5 in advance by an air pump (not shown in the figure), and the ammunition 2 to be launched is pre-loaded in the launch tube 3, and then the launch tube 3 is installed in the launch body 1. The air flow conversion mechanism is controlled by the launch switch, so that the high-pressure gas in the gas storage chamber can enter the launch tube, thereby driving the ammunition to be launched at high speed.

[0030] In a specific embodiment of the present invention, Figure 1 , 2 As shown, the airflow conversion mechanism includes a partition 9, a valve flap 11 and a solenoid valve 12. The partition 9 is arranged in the middle of the pneumatic cavity 6 to isolate the transition cavity 13 from the rear thereof. A vent hole 14 is arranged in the middle of the partition 9. The valve flap 11 is arranged in the pneumatic cavity 6. The valve flap 11 that can move left and right is used to block the air inlet end and the vent hole 14 of the launch tube 3 respectively. An elastic convex ridge 110 is arranged around the valve flap 11. The solenoid valve 12 is connected to the launch switch 8 and the battery 4. The solenoid valve 12 is arranged at the exhaust port of the transition cavity 13. The air inlet of the transition cavity 13 is connected to the inflation tube 7. The solenoid valve is a pneumatic valve, and the battery is used to power the circuit system composed of the launch switch and the solenoid valve. During inflation, the solenoid valve is closed, and the gas enters the gas storage chamber through the edge of the valve disc; during launch, the launch switch controls the solenoid valve to open, and the gas in the pneumatic cavity on the right side of the valve disc is discharged into the transition cavity through the vent and discharged through the solenoid valve. When the pressure on the left side of the valve disc is greater than the pressure on the right side, the valve disc can move toward the vent side. At the same time, the valve disc releases the blockage of the launch tube, thereby releasing a large amount of compressed gas in the gas storage chamber into the inner cavity on the right side of the launch tube, and then the high-pressure airflow pushes the ammunition with medicine in the launch tube to be fired.

[0031] The inflation tube 7 is provided with a one-way valve 19, which is arranged inside the launcher body 1. The air storage chamber is inflated with an air pump before use, and after the air pump is removed, air leakage can be avoided with the help of the one-way valve;

[0032] Of course, the airflow conversion mechanism is not limited to the above structure, and a T-type three-way ball valve can also be used, which is installed in the pneumatic cavity. The three-way ball valve can realize the function of storing and releasing compressed air: when inflating, the gas enters the air storage chamber through the inflation pipe and the three-way ball valve; when launching, the gas in the air storage chamber enters the inner cavity of the launch tube through the three-way ball valve to complete the launch.

[0033] When making specific Figure 3 As shown, the valve flap 11 is designed to be bowl-shaped, the diameter of the main body 111 of the valve flap 11 is larger than the diameter of the vent 14, and the thickness of the convex eaves 110 is smaller than the thickness of the main body 111. The valve flap is made of flexible materials such as rubber and silicone, and the thickness of the convex eaves gradually decreases from the main body to the edge. With this structure of the valve flap, the airflow can flow from the bottom side of the valve flap to the side of the bowl mouth, and then enter the pneumatic cavity from the edge of the flexible convex eaves, and then enter the gas storage chamber to complete the storage of high-pressure gas.

[0034] Further optimize the above technical solution, such as Figure 2 As shown, a launch sleeve 15 is provided inside the launcher body 1, and the gas storage chamber 5 is arranged below the launch sleeve 15; the launch tube 3 can be inserted into the launch sleeve 15, and the launch sleeve 15 and the launch tube 3 are positioned by a clamping structure. Among them, the clamping structure includes a limiting protrusion 16 and a limiting groove 17 matched therewith, the limiting protrusion 16 is arranged on the outer wall of the launch tube 3, and the limiting groove 17 is correspondingly arranged on the inner wall of the launch sleeve 15. Among them, the protrusion can adopt a plurality of spherical crown convex points, and can also adopt an annular convex ring. The use of the clamping structure can ensure the reliable positioning of the launch tube 3 in the launcher body 1, and facilitate the fixing and removal of the launch tube at any time after the launch tube is inserted into the launch sleeve; at the same time, the inner diameter of the launch sleeve is slightly larger than the outer diameter of the launch tube, ensuring that the launch tube can overcome the resistance of the limiting groove under the impact of the high-pressure airflow and quickly eject from the launch sleeve.

[0035] When designing specifically, Figure 2 As shown, the launch sleeve 15 is a tube body with two ends open, one end of the launch sleeve 15 is connected to the inner wall of the launcher body 1 on the inner side of the launch port 10, the other end of the launch sleeve 15 is provided with a step that matches the end of the launch tube 3, and the outside is provided with an extension tube 18 extending into the pneumatic cavity 6, and the valve flap 11 can block the tube mouth of the extension tube 18. Among them, the outer diameter of the tube mouth of the extension tube 18 is slightly smaller than the outer diameter of the left side of the main body 111 of the valve flap 11, ensuring that the valve flap 11 can block the launch sleeve during the inflation process.

[0036] Further optimize the above technical solution, such as Figure 1As shown, a reed switch 20 is provided on the outer wall of the launch sleeve 15, and the reed switch 20 is connected to the solenoid valve 12 and the battery 4; a magnet is provided in the ammunition 2. During assembly, the reed switch is embedded in the outer side of the launch sleeve, mainly for safety purposes, and can also be replaced by a Hall sensor with similar functions. The reed switch is an electronic component, which is essentially a magnetically controlled switch. The reed switch is connected to the electronic circuit of the drug launcher to control whether to launch or not: when there is a magnet in the ammunition, it can be turned on, otherwise it will not be turned on. The use of this solution can prevent the drug launcher from being used by criminals to launch other objects, thereby improving the safety factor. The application process is as follows:

[0037] After installing a magnetic control sensor element such as a reed switch inside the launcher body 1, a magnet of a specific size is implanted in the ammunition to be launched. When the reed switch senses the magnet, the drug launcher is allowed to launch. In this way, the drug launcher can only be used to launch special ammunition, limiting the launcher from being used for other purposes.

[0038] In the specific design, the inlet end of the inflation tube 7 extends to the outside of the launcher body 1, and the inflation pump can be a manual or electric air pump. The launcher body adopts a rectangular box body, and the card slots for fixing the air storage chamber, pneumatic cavity, launch sleeve, one-way valve and solenoid valve can be installed on the inner wall of the box body. Depending on the use requirements, the ammunition can use an anesthetic needle, etc., and a magnet of a specific size is built in, which can cooperate with the reed switch to achieve a safer launch function.

[0039] For easy operation, a handle 21 is provided at the rear of the transmitter body 1, and both ends of the handle 21 are connected to the transmitter body 1. The button of the launch switch 8 is provided on the inner surface of the handle 21 and corresponds to the index finger. In the specific manufacturing process, the handle and the transmitter body can be integrally injection molded.

[0040] like Figure 4-7 As shown, the specific application process of the utility model is as follows:

[0041] 1. Inflation stage. Figure 4 As shown in the figure, during this process, the inflation tube outside the one-way valve is connected to the external air pump, and the gas flows through the one-way valve and enters the gas storage chamber through the edge of the rubber valve disc. At this time, the pressure on the right side of the rubber valve disc is greater than that on the left side, and the rubber valve disc will firmly support the launch sleeve tube mouth to prevent gas leakage.

[0042] 2. Launch phase.

[0043] (1) When it is necessary to launch, press the launch switch. If there is ammunition with magnet in the launch tube, the "battery - launch switch - reed switch - solenoid valve" will form a correct path, and the solenoid valve will open normally. At this time, the gas in the driving chamber and transition chamber on the right side of the rubber valve disc will be discharged from the solenoid valve. Figure 5 shown.

[0044] (2) When the gas on the right side of the rubber valve disc is discharged, the air pressure on both sides is instantly unbalanced because the left side is connected to the air storage chamber, and the high-pressure gas will push the rubber valve disc to move to the right ( Figure 6 The arrow in the middle ellipse represents the movement direction of the valve disc) until the valve disc blocks the vent hole on the right.

[0045] (3) The gas chamber is then connected to the launch tube, and high-pressure gas is discharged from the launch tube, pushing the ammunition in the tube out (e.g. Figure 7 As shown), the launch is completed.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the scope of protection of the claims of the utility model.
