[0028] Reference Figures 1-4As shown, an inertial trigger high-pressure gas injection device includes a bottle body 1, a base 2 and a piercing member 3, the bottle body 1 is provided with a sealing member 4, the sealing member 4 forms a sealed cavity inside the bottle body 1, the bottle body 1 is filled with compressed gas, the base 2 is fixedly connected to the bottom of the bottle body 1, the piercing member 3 is provided with a gas passage 5, the front end of the piercing member 2 is provided with a gas outlet hole 6, the tail part is provided with a gas inlet hole 7, the gas outlet hole 6 and the gas inlet hole 7 are communicated with the gas passage 5, the piercing member 3 is movably connected to the base 2, the piercing member 3 is moved towards the bottle body 1 under the external pushing force to pierce the sealing member 4 at the tail part, and the compressed gas in the bottle body enters the piercing member and is discharged from the gas outlet hole. In use, it is especially suitable for throwing operation, manual throwing, or throwing by a drone. After the piercing part contacts the target object, it will be resisted and cannot continue to move forward. At this time, due to the inertial force, the piercing part will move in the opposite direction, i.e. towards the bottle body, and the tail part of the piercing member will pierce the sealing member in the bottle body.
[0029] The tail end of the piercing member 3 is provided with a tail tip 8, the front end of the piercing member 3 is provided with a front tip 9, the front tip 9 and the tail tip 8 are conical, the front tip 9 is used to contact the target object to form a fixed piercing, and the tail tip 8 is used to pierce the sealing member 4 to ensure the effectiveness of the piercing. The piercing member can be a column made of metal material or made of plastic material with high hardness.
[0030] In order to improve the gas flowability, the tail tip 9 is provided with an exhaust groove 10, and the exhaust groove 10 is communicated with the gas inlet hole 7. The gas inlet hole can not be arranged at the tail tip, and the exhaust groove is used for guiding the gas to enter the gas passage from the gas inlet hole.
[0031] The base 2 is provided with an axial through hole, the bottom of the base 2 is provided with a movable cavity 11, the axial through hole is communicated with the movable cavity 11, the bottom surface of the base 2 is provided with a bottom plate 12, the bottom plate 12 is provided with a perforation 13 for the tail tip 8 to pass through, the piercing member 3 is inserted into the axial through hole and the tail tip 8 extends into the movable cavity 11, a blocking wall 14 is formed between the tail tip 8 and the side wall of the piercing member 3, and the tail tip 8 completely inserted into the perforation 13 will enter the bottle body 1 and pierce the sealing member 4. The blocking wall 14 is used to fit the bottom plate area around the perforation 13 to limit the movement stroke of the tail tip 8, so as to avoid that the movement stroke of the piercing member is too large. The side wall of the axial through hole is in contact with the side wall of the piercing member to form a friction force, and the friction force is greater than the gravity of the piercing member itself, so as to form a certain resistance to avoid that the piercing member slides towards the bottle body due to the gravity itself when there is no external force or inertia. The friction force can be realized by roughness setting of the side wall of the axial through hole.
[0032] The front end of the base 2 is provided with a tray 15, and the tray 15 is provided with a plurality of top piercing members 16. When the piercing member pierces into the target object to a large depth, it will be blocked by the top piercing members to form a limit.
[0033] The base 2 and the bottle body 1 are installed through a threaded structure, the threaded structure is arranged on the inner wall of the port of the bottle body and the outer wall of the bottom of the base, the base is placed to be installed and fixed with the bottle body, and installation and disassembly are relatively convenient.
[0034] The sealing member 4 in the bottle body 1 can be a sealing film, and the position of the sealing member is arranged to ensure that the sealing member can be pierced by the tail end.
[0035] The bottle body 1 is provided with a tail wing 17, which is helpful for the flight of the whole body to remain stable when being thrown, and a plurality of tail wings can be arranged.
[0036] The bottom of the bottle body 1 is provided with a hook 18, which is beneficial to suspension when being used in cooperation with equipment such as a drone.
[0037] In addition, with reference to Figure 5 In addition, with reference to
[0038] When being thrown and flown, the front end of the piercing member is kept perpendicular to the ground at the end of flight, the stability during flight and the landing point are not deviated, and the influence of the posture of the device before falling on the landing point is reduced. For example, if the device tilts by 5° at the moment of falling, the air resistance of the wing surface on one side of the wing plate is large, a large lift is generated, the wing surface on the other side of the wing plate is in a leeward area, a small lift is generated, a lift difference is formed between the two sides of the wing plate, the whole injection device rotates around the center of gravity, and the posture of the side deviation is corrected. This correction method also has the same correction ability for crosswind in a certain wind speed range, so that the device can be vertically landed and the landing point deviation is reduced, and the device can more accurately enter the target object.
[0039] The utility model can be applied to various occasions, that is, the air outlet can be realized by manual pushing, and the air outlet can also be realized by throwing operation. The following will be described by taking the throwing operation as an example.
[0040] After being thrown, the whole body flies towards the target object, when the front tip of the piercing member contacts the target object, then the front tip pierces into the target object, when the front tip contacts the target object, the target object also forms resistance, at this time, there is also flight inertia, the piercing member moves towards the bottle body relative to the bottle body, the piercing member moves in the axial through hole of the base, so that the tail tip passes through the perforation of the bottom plate into the bottle body, thereby breaking the sealing member, the high-pressure gas in the bottle body enters the gas passage of the piercing member through the air inlet hole, and then is discharged from the air outlet hole into the inside of the target object.
[0041] It should be noted that the above is only the preferred embodiment of the present application, and is not intended to limit the present application, although the present application is described in detail with reference to the embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, but any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
