Abstract:
A gas balance training bomb uses primarily a pressure of gas to substitute a gunpowder explosion to generate a gas thrust for pushing an eruption solid, powder, gas or liquid, so as to achieve an effect of simulating an explosion. The gas balance training bomb is formed with a passive gas chamber and an active gas chamber, the passive gas chamber stores the gas needed upon erupting and the active gas chamber stores the gas used for controlling an eruption time. Through the pressure difference between the active gas chamber and the passive gas chamber, the gas stored in the passive gas chamber is released momentarily to accomplish an operation of eruption, such that the effect of simulating the explosion can be achieved.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    a) Field of the Invention 
         [0002]    The present invention relates to a gas balance training bomb, and more particularly to a gas balance training bomb which uses primarily a pressure of natural gas to substitute a gunpowder explosion to generate a gas thrust to push an eruption solid, powder, gas or liquid, thereby achieving an effect of simulating an explosion, being able to be used in training military personnel or policemen, entertaining or simulating the explosion, as well as being used very safely. 
         [0003]    b) Description of the Prior Art 
         [0004]    Most of existing training bombs for training military personnel or policemen or simulating an explosion are filled with gunpowder of a smaller explosion power or natural gas, especially the gunpowder of smaller explosion power. These training bombs are more expensive and relatively more dangerous. In addition, when the gunpowder explodes, the training bomb cannot be used again. Therefore, for a training institute, these training bombs will be a kind of training equipment of high cost. 
         [0005]    On the other hand, almost all the existing gas-filled training bombs have only an effect of one-way eruption; that is, the eruption can be only occurring at the most front end of the training bomb. However, for the training institute, the simulation effect will be very poor and a real experience cannot be achieved. Furthermore, although the existing gas-filled training bombs can be recycled for use, their parts are mostly distributed, allowing the parts to be dropped everywhere after being used, thereby causing trouble in recycling. 
         [0006]    Moreover, for the aforementioned training bomb whether being filled with the gunpowder or gas, its eruption time cannot be adjusted according to a user&#39;s requirement, which causes inconvenience in use. 
         [0007]    Accordingly, how to improve the aforementioned problems is a technological issue to be solved by the present invention. 
       SUMMARY OF THE INVENTION 
       [0008]    The primary object of the present invention is to provide a gas balance training bomb which is extremely safe in use and can truly simulate an explosion. 
         [0009]    Accordingly, the gas balance training bomb of the present invention is primarily formed with a passive gas chamber and an active gas chamber, wherein the passive gas chamber is used to store gas needed upon erupting, and the active gas chamber stores gas which is used for controlling an eruption time, such that through a pressure difference between the active gas chamber and the passive gas chamber, the gas that is stored in the passive gas chamber is released momentarily to accomplish the eruption operation, thereby achieving an effect of simulating the explosion. 
         [0010]    The gas balance training bomb of the present invention includes primarily an outer casing, an interior of which is provided with an inner tube sheath, a gas guiding assembly, an inner sleeve, a piston and a gas storage cylinder, wherein a tube wall of a tube unit of the outer casing is provided with a plurality of gas discharge holes, with each gas discharge hole being installed with an eruption material that can be a solid, powder or liquid. 
         [0011]    The inner sleeve is a hollow tube unit, a tube wall of which is provided with a plurality of through-holes; whereas, the inner tube sheath and the gas storage cylinder are provided respectively at two ends of the inner sleeve, and constitute a gas storage space with the inner sleeve. The piston is provided in the inner sleeve to separate the gas storage space into the active gas chamber and the passive gas chamber, and the gas guiding assembly is transfixed into the inner tube sheath, with one end being protruded at an exterior of the tube unit, and the other end being abutted on the piston, such that gas can be flooded from the gas guiding assembly that is protruded at the exterior of the tube unit into the gas storage space inside the tube unit to completely fill the active gas chamber and the passive gas chamber and to keep the piston at a balance state. 
         [0012]    Upon operating, the gas of the active gas chamber is released first, so as to constitute an imbalance state to the gas pressure between the active gas chamber and the passive gas chamber; that is, the gas pressure of the passive gas chamber is larger than that of the active gas chamber, which in turn pushes the piston, allowing a residual pressure in the active gas chamber to push off the piston to pass through the inner sleeve, and the residual pressures of the passive gas chamber and the active gas chamber to be expelled out through the gas discharged holes on the tube unit at a same time. At this time, the eruption materials installed in the gas discharge holes will be driven by the gas pressure in the active gas chamber to erupt out, thereby achieving an effect of simulating the explosion. 
         [0013]    Another object of the present invention is to provide a gas balance training bomb, wherein an eruption time of the entire gas balance training bomb can be controlled. When the gas balance training bomb is filled, the gas is primarily filled into the interior of the training bomb, allowing the gas pressures in the active gas chamber and the passive gas chamber to be balanced. Therefore, the gas pressure in the passive gas chamber becomes a key factor for controlling the eruption of the active gas chamber; that is, the larger the gas pressure of the passive gas chamber is, the longer the eruption time will be; on the other hand, the smaller the gas pressure of the passive gas chamber is, the shorter the eruption time will be. Accordingly, the gas pressure in the passive gas chamber can be adjusted according to training sites. 
         [0014]    Still another object of the present invention is to provide a gas balance training bomb which can be recycled for filling repeatedly. As upon erupting, the internal piston is operated only by using the gas pressure difference, each part will not be dropped everywhere. Therefore, the parts can be recycled for filling after simulating the explosion, thereby being able to be used repeatedly. 
         [0015]    To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0022]    Referring to  FIG. 1  and  FIG. 2 , it shows a perspective view and an exploded view of a gas balance training bomb of the present invention, which comprises primarily an outer casing  10 , an interior of which is in a hollow shape and is provided with an inner tube sheath  20 , a gas guiding assembly  30 , an inner sleeve  40 , a piston  50  and a gas storage cylinder  60 . In the present invention, the outer casing  10  is further constituted by a tube unit  11  and a cover unit  12 , wherein the tube unit  11  is a hollow tube and is covered by the cover unit  12  to form an emplacement space in the outer casing  10 , further enabling the inner tube sheath  20 , the gas guiding assembly  30 , the inner sleeve  40 , the piston  50  and the gas storage cylinder  60  to be assembled in the emplacement space orderly. A tube wall of the tube unit  11  is provided with a plurality of gas discharge holes  13 , a tube wall of the inner sleeve  40  is provided additionally with a plurality of through-holes  41 , and the gas guiding assembly  30  is further composed of a nozzle  31 , a guide tube  32  and a gas choking tube  33 ; whereas, a front end at an exterior of the outer casing  10  is further disposed with a head member  14 . 
         [0023]    Referring to  FIG. 2  and  FIG. 3 , it shows respectively an exploded view and a cutaway view of the present invention. In assembling, the inner tube sheath  20  and the inner sleeve  40  are emplaced respectively in an interior of the tube unit  11  of the outer casing  10 , such that the inner sleeve  40  is sheathed on the inner tube sheath  20  and then the gas guiding assembly  30  is orderly emplaced inside the inner tube sheath  20 , allowing the guide tube  32  of the gas guiding assembly  30  to pass through the inner tube sheath  20  and the head member  14  and to protrude out of the head member  14 . On the other hand, the nozzle  31  is sheathed at the guide tube  32  and is protruded at an end of an exterior of the head member  14 , the gas choking tube  33  is installed on the piston  50  and the piston  50  is emplaced inside the inner sleeve  40 . Finally, the gas storage cylinder  60  is emplaced inside the tube unit  11 , and constitutes a gas storage space with the inner tube sheath  20  and the inner sleeve  40 , with the gas storage space being separated into an active gas chamber  70  and a passive gas chamber  80  through the piston  50 . In addition, each gas discharge hole  13  on the tube wall of the tube unit  11  is used for installing an eruption material (not shown in the drawings) which can be a solid, powder or liquid. 
         [0024]    Accordingly, after the entire gas balance training bomb has been assembled, the gas can be filled into the training bomb through the nozzle  31  that is exposed, enabling the gas to pass through the gas guiding assembly  30  to be stored between the active gas chamber  70  and the passive gas chamber  80 , with a flow route of the gas shown as arrows in the drawings. Therefore, the gas pressure between the active gas chamber  70  and the passive gas chamber  80  will be balanced, allowing the piston  50  to keep at a balance position. In the present invention, the filling gas is the natural gas. 
         [0025]    Referring to  FIG. 4 , it shows a local exploded view of the present invention. When assembling the guide tube  32  and the gas choking tube  33  of the gas guiding assembly  30 , a proper gap is provided between the guide tube  32  and the gas choking tube  33 ; therefore, when the gas is filled into the active gas chamber  70  and the passive gas chamber  80  through the nozzle  31 , the gas can be guided into the passive gas chamber  80  by the gap between the guide tube  32  and the gas choking tube  33 . In a mean time, a part of the gas will be guided into the active gas chamber  70  through the gas choking tube  33 , further achieving the gas pressure balance between the active gas chamber  70  and the passive gas chamber  80 , such that the piston  50  is abutted at an exterior of the gas storage cylinder  60 , enabling the active gas chamber  70  to form a sealed condition, thereby being able to store the gas. 
         [0026]    Referring to  FIG. 5 , it shows a cutaway view of a first operation of the present invention. In using the gas balance training bomb of the present invention, the gas in the passive gas chamber  80  should be released first, which is reached primarily by the head member  14 . When the gas of the passive gas chamber  80  is released, due to an operation of the gas pressure, the guide tube  32  will be pushed outward by the gas pressure, further enabling the gas inside the passive gas chamber  80  to be expelled outward through the guide tube  32 . 
         [0027]    Referring to  FIG. 6 , it shows a cutaway view of a second operation of the present invention. After the gas of the passive gas chamber  80  has been released, a pressure difference will be resulted between the active gas chamber  70  and the passive gas chamber  80 ; that is, the gas pressure inside the active gas chamber  70  is larger than that inside the passive gas chamber  80 , further enabling the gas pressure inside the active gas chamber  70  to push the piston  50 , such that the piston  50  is moving in the inner sleeve  40  toward the passive gas chamber  80  to result in a proper distance between the piston  50  and the gas storage cylinder  60 , further enabling the gas inside the active gas chamber  70  to be released outward and expelled outward through the through-holes  41  on the inner sleeve  40 . 
         [0028]    At this time, the gas inside the active gas chamber  70  will enter into the emplacement space of the outer casing  10 . As the tube wall of the tube unit  11  is provided with the plurality of gas discharge holes  13 , and each gas discharge hole  13  is disposed with the eruption material, therefore, after the gas has entered into the outer casing  10 , the gas will pass through the gas discharge holes  13  on the tube wall of the tube unit  11 , and be expelled outward (along a direction pointed by the arrows in the drawings). Accordingly, at a same time when the gas is expelled out, the eruption materials on the gas discharge holes  13  will be expelled out too, thereby achieving an effect of simulating an explosion. 
         [0029]    In addition, referring to  FIG. 4 , when the gas balance training bomb of the present invention is filled with the gas, the gas is especially guided into a place between the active gas chamber  70  and the passive gas chamber  80  through the guide tube  32  from the nozzle  31 . Therefore, during the process of filling the gas, if the passive gas chamber  80  is given a larger gas pressure, then the gas pressure inside the passive gas chamber  80  will be larger than that inside the active gas chamber  70 , thereby delaying an eruption time of the active gas chamber  70 . On the contrary, if during the process of filling the gas, the passive gas chamber  80  is given a smaller gas pressure, then the gas pressure of the passive gas chamber  80  will be smaller than that of the active gas chamber  70 , thereby accelerating the eruption time of the active gas chamber  70 . Accordingly, the eruption time can be adjusted according to a user&#39;s requirement. 
         [0030]    Furthermore, when the present invention is operating, the effect of simulating the explosion is achieved primarily by using the gas pressure difference between the active gas chamber  70  and the passive gas chamber  80 . Therefore, an operation of each part is conducted inside the outer casing  10 , and during the process of simulating the explosion, the parts will not be dropped everywhere. Accordingly, in addition to adding a safety in use, the effect of recycling to refill the gas can be achieved as well. 
         [0031]    It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
