Description:
BACKGROUND OF THE INVENTION 
       [0001]    a) Field of the Invention 
         [0002]    The present invention relates to a fire igniter of carbonaceous fuel, and more particularly to a barrel-shape fire igniter which provides an initial operation to ignite cold and raw carbonaceous fuel. 
         [0003]    b) Description of the Prior Art 
         [0004]    As the carbonaceous fuel can be carried safely for use in a cook-out, and ashes after burning can be used as fundamental elements of an organic fertilizer, most of the cook-outs or barbecues will use the carbonaceous fuel as a fire source, including coke, charcoal or plant coal formed by densification. 
         [0005]    As a density of the carbonaceous fuel is close to that of wood or even the coke, and the carbonaceous fuel is in a grainy shape, fire cannot be ignited immediately due to a restriction of fire power of flares; hence, an ignition operation should be performed to a pile of carbonaceous fuel. 
         [0006]    Referring to  FIG. 1 , it shows a perspective view of a conventional fire igniter, wherein a barrel-shape fire igniter  1  includes a barrel unit  10  which surrounds a fire chamber  100 , and a side of which is connected with a handle  11  and an auxiliary handle  12  through a connection plate  13 . After an interior of the fire chamber  100  is emplaced with the carbonaceous fuel, a kindling fire is made to ignite the fire within the fire chamber  100 . By the barrel unit  10 , a side wind and an unnecessary heat loss can be avoided, allowing flames after igniting the carbonaceous fuel at a bottom layer to attack toward the carbonaceous fuel stacked at upper layers, so as to achieve a complete pre-heating and ignition. 
         [0007]    When most of the grainy carbonaceous fuel can be combusted by themselves, they are poured into a barbecue oven or a cook-out oven to carry out a thermal work. Due to that in a conventional design, the barrel unit  10  is a cylindrical barrel with a fixed cross section; hence, it is not collected easily when carrying. Furthermore, as the interior of the barrel unit  10  is dirty, other objects cannot be put in there. On the other hand, the handle is usually fixed; therefore, a rather large volume will be occupied in the carrying space. 
       SUMMARY OF THE INVENTION 
       [0008]    Accordingly, a primary object of the present invention is to provide a fire igniter of carbonaceous fuel which can be deformed for collection and includes primarily a front plate, a side wing and a rear plate, with the front plate being able to be folded toward the rear plate, so as to largely reduce a collection space. 
         [0009]    A second object of the present invention is to provide a fire igniter of carbonaceous fuel, wherein a handle can be folded reversely for collection through a connection method. 
         [0010]    A third object of the present invention is to provide a fire igniter of carbonaceous fuel, wherein a grate which divides the carbonaceous fuel can be deformed to enlarge a bottom area, so as to facilitate igniting the fire. 
         [0011]    A fourth object of the present invention is to provide a fire igniter of carbonaceous fuel, wherein a side wing is formed by connecting two foldable plates through hinges, and is collected inward. 
         [0012]    A fifth object of the present invention is to provide a fire igniter of carbonaceous fuel, wherein the grate can be fastened by a latching element on a rear plate, so as to prevent the grate from dropping out when pouring the carbonaceous fuel. 
         [0013]    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 
       [0024]    Referring to  FIG. 2 , a fire igniter  1  of the present invention comprises a deformable barrel unit  1 , a rear side of which is connected to a lifting handle  4  and an auxiliary handle  40  through a rear plate  22 , allowing the barrel unit  1  to be carried and the carbonaceous fuel to be poured by two hands. The deformable barrel unit  2  comprises the rear plate  22  which is connected to a front plate  21  through a side wing  23 , and the side wing  23  is formed by connecting two foldable plates  231 ,  232  with a butt hinge  230 ; whereas corners between the side wing  23  and the rear plate  22 , and corners between the side wing  23  and the front plate  21 , are connected with corner hinges  220 . After unfolding the barrel unit  2 , a grate  3  is placed across an interior of a waist part, and below the grate  3  is opened outward with an air intake  25  for replenishing needed oxygen. 
         [0025]    The grate  3  can be further transversally placed across the interior of the waist part of the deformable barrel unit  2  with support elements  24  across which sides of the grate  3  are placed. 
         [0026]    A side of the rear plate  22 , at an upper rim of the grate  3 , is provided with a latching element  240  for fastening the grate  3 , such that when pouring the carbonaceous fuel, the grate  3  will not fall out. The latching element  240  can be further in a hook shape, and if the deformable barrel unit  2  is operated to result in an excessively large pouring angle, then the grate  3  will be formed as a swing condition without falling out, by being hooked with a hook part of the latching element  240 . 
         [0027]    Referring to  FIG. 3 , the rear plate  22  is connected with the front plate  21  with the side wing  23  which is formed by connecting the foldable plates  231 ,  232  with the butt hinge  230 . The butt hinge  230  is located outside, and the corner hinges  210 ,  220  which join the side wing  23  with the front plate  21  and the rear plate  22  are located at inner sides of the corners. Therefore, in a collection process, the foldable plates  231 ,  232  will be collapsed toward an inner space. Referring to  FIG. 4 , the butt hinge  230  for the foldable plates  231 ,  232  is indented toward the inner space, forming a linking rod operation which allows the front plate  21  to be indented with respect to the rear plate  22 , thereby achieving an object of shrinking a volume to facilitate carrying and collecting. 
         [0028]    Referring to  FIG. 5 , it shows a schematic view of an ignition operation. After unfolding the deformable barrel unit  2 , an interior of the barrel unit  2  is placed with carbonaceous fuel  300  in stacks. By a division of the grate  3 , kindling fire  30  can attack from below and pass through spaces divided by the grate  3 , allowing flames to attack toward a bottom of the carbonaceous fuel  300 . After the carbonaceous fuel  300  at a bottom layer is ignited, and when fire power attacks toward the carbonaceous fuel  300  above, an entire surface of the carbonaceous fuel  300  will be burning to achieve a self-combustion state. When a part or most part of the carbonaceous fuel  300  is self-combusted, the carbonaceous fuel  300  can be poured out by operating the lifting handle  4  and the auxiliary handle  40 . On the other hand, the oxygen needed for ignition is fed in through the air intake  25 . 
         [0029]    Referring to  FIG. 6 , the lifting handle  4  is provided at an exterior side of the rear plate  22 , and is connected to the rear plate  22  by a cross-over bracket  41 . An end of the cross-over bracket  41  is provided with a connection seat  42  for connecting the auxiliary handle  40 , and a rod body  401  of the auxiliary handle  40  is fastened by a notch  421  of the connection seat  42 . Therefore, when the auxiliary handle  40  is opened to a maximum angle, its rod body  401 ,  402  will be latched in the notch  421 ,  422  due to an elastic deformation effect, thereby achieving a fixing function and facilitating to acquire an efficient direction for exerting force upon operating. 
         [0030]    Referring to  FIG. 7 , in a further embodiment of the present invention, the handle can be collected, wherein a wavy cross-over bracket  54  is used to connect a U-shape foldable handle  5 , and U-shape side ends of the foldable handle  5  are provided respectively with a pivot hole  51 ,  52 , such that the foldable handle  5  can be connected to corresponding sides of the cross-over bracket  54 . In addition, a turnable auxiliary handle  50  is connected at inner sides of the cross-over bracket  54  over which the foldable handle  5  is across, and an inner space  503  between rod bodies  501 ,  502  of the auxiliary handle  50  is wider than a width of the foldable handle  5 . If the auxiliary handle  50  is folded backward, then the rod bodies  501 ,  502  will be placed in grooves  541 ,  542  of the wavy cross-over bracket  54 . On the other hand, when the auxiliary handle  50  is flipped to an operation angle, it will be crossed obliquely over corresponding sides of the foldable handle  5 , with a cross point being able to position the foldable handle  5  vertically. 
         [0031]    A positioning element  53  is provided on a corresponding rod body of the foldable handle  5  at the cross point, and is provided with indented notches  531  for fastening the rod bodies  501 ,  502  of the auxiliary handle  50  to facilitate the positioning that allows the foldable handle  5  to be perpendicular to the rear plate  22 , and allows the auxiliary handle  50  to be positioned at an opened angle. 
         [0032]    Referring to  FIG. 8 , the auxiliary handle  50  is first collected into the grooves  541 ,  542  of the wavy cross-over bracket  54 , and the foldable handle  5  can be folded by itself to be collected toward the rear plate  22 , wherein a notch  55  is provided at a position of the foldable handle  5 , corresponding to the rod body  501  of the auxiliary handle  50 , allowing the foldable handle  5  to be placed flat on the rear plate  22 . 
         [0033]    Referring to  FIG. 9 , the deformable barrel unit  2  is formed by the front plate  21  and the rear plate  22  that are connected with the side wing  23  through the corner hinges  220 ,  210 ; whereas, the side wing  23  is formed by connecting the foldable plates  231 ,  232  through the butt hinge  230 . After unfolding the deformable barrel unit  2 , a stretching effect will be formed between the front plate  21  and the rear plate  22  through the side wing  23 . 
         [0034]    Referring to  FIG. 10 , a deformable grate  6  is formed as a foldable shape by using a cross hinge  60  which is connected at a center of a breadth surface of the deformable grate  6 . As a maximum length of the deformable grate  6  after deformation is greater than a pitch of the barrel unit  2  after being unfolded, the deformable grate  6  will be formed as a sharp cone surface like a roof top, after being placed into the barrel unit  2  and pushed by the support elements  24 . By the oblique cone surface, a contact area at the bottom for receiving the kindling fire  30  will be enlarged, so as to accelerate combustion and expand the area in contact with oxygen. A side of the deformable grate  6  with respect to the rear plate  22  can be also hooked by the latching element  240  to prevent from falling out upon pouring the carbonaceous fuel. The deformable grate  6  is in a pike shape and a pressure P will be formed when the deformable grate  6  is loaded by filling in the aforementioned carbonaceous fuel. As an oblique force P 3  will be formed by a combination of the pressure P and a horizontal force P 2 , the deformable grate  6  will be pressed and secured. On the other hand, a larger supportive force can be also formed by the deformable grate  6 ; therefore, the deformable grate  6  can be made by a wiring material of a smaller diameter, so as to save the material and facilitate collection. 
         [0035]    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.
