       BACKGROUND OF THE PRESENT INVENTION 
       [0002]    1. Field of Invention 
         [0003]    The present invention relates to an air-water punching bag structure, in particularly, a bag structure which weight and firmness can be adjusted and which has multi-training functions. 
         [0004]    2. Description of Related Arts 
         [0005]    Conventional punching bag for combat training is a closed bladder using solid (such as sand), liquid (such as water), or gas (such as air) as filler and is placed inside of an external bag. 
         [0006]    It is easy and cheap to obtain the fillers, but the ideal weight of a punching bag, which may impact the training effect, is about half of its user&#39;s weight. Also, when solid is used as filler in inner bladder, the weight of the punching bag becomes too heavy to be easily moved or stored. When liquid is solely used as the filler of the inner bladder, the heavy weight of punching bag will result in poor training effect. When gas is used as filler of the inner bladder, the punching bag is usually too light and requires other material to fix it in place. Thus, all of the above can result in poor training effect. 
         [0007]    In addition, for conventional punching bag structure which adopts solid, liquid, or gas as filler, there is only one tactile feel. When filling with solids, punching bag gives a firm texture while liquids add a little softness and resilience. When filling with gas, punching bag is even more resilient. However, none of the foregoing fillers can be adjusted in the same structure to create different texture to satisfy different training techniques and users. 
         [0008]    In addition, the conventional punching bag structure cannot integrate different training functions simultaneously (such as croissant move training, push-up training, sit-up training, Judo training, boxing training, upper cut training, tackle training, suppression training, and weight training). More training equipments need to be purchased in order to provide different training functions when using punching bag for different technique training, which further increases the training cost. Thus, the drawbacks of conventional punching bag need to be improved. 
       SUMMARY OF THE PRESENT INVENTION 
       [0009]    To overcome the existing problems of prior art, the present invention provides an air-water punching bag structure that uses liquids or colloid as the major weight source for the inner bladder structure and fills up the extra space with air. The external bag structure can integrate suspenders or handles to lower training cost and the weight and softness-hardness can be adjusted to meet the user&#39;s demand with different training functions for obtaining the training effect. 
         [0010]    The present invention discloses an air-water punching bag structure that comprises an inner bladder, an external bag, at least one set of handles, at least two sets of first suspenders, and at least one set of second suspenders.

The connecting part  251  is located in one area of the connecting strap  25 , but not fixed on the body  21 , while the other areas of the connecting strap  25  are fixed on the body  21 . 
         [0030]    The handle set  30  is removable and has multiple handles at different locations and one connecting part  31 . The connecting part  31  is located on one end of the handle set  30  and can be fixed on the connecting part  251  of the connecting strap  25 . The first suspender set  40  is removable and one end of each the first suspender set  40  can go through the connecting part  251  of each the connecting strap  25  and between the external bag  20  body  21 . The second suspender set  50  is removable and the length thereof is adjustable and one end thereof can be fixed on the out layer of the external bag  20  body  21 . 
         [0031]    First, the inner bladder  10  was put into the external bag  20  and the inner bladder  10  of the gas container  11  was injected with air via the air valve  111  on the gas container  11 . The volume of the gas container  11  will increase due to the pressure increase inside the gas container  11  and then the volume of the inner bladder  10  of the liquid container  12  will be reduced. 
         [0032]    Then the water inlet set  121  on the liquid container  12  is opened to allow the user to add certain amount of liquid or colloid into the inner bladder  10  of the liquid container  12  via the water inlet set  121  on the liquid container  12 . Meanwhile, the top of liquid or colloid inside the inner bladder  10  of the liquid container  12  is filled with air. 
         [0033]    Finally the water inlet set  121  on the liquid container  12  is closed and the air valve  122  on the liquid container  12  is opened for injecting air into the inner bladder  10  of the gas container  11  via the air valve  111  of the gas container  11 . The volume increases due to the pressure increases inside the inner bladder  10  of the gas container  11  and thus decreases the volume of the inner bladder  10  of the liquid container  12 . Meanwhile, the level of liquid or colloid inside the inner bladder  10  of the liquid container  12  will rise due to compression and the air inside the inner bladder  10  of the liquid container  12  will be exhausted via the air valve  122  until the liquid or colloid inside the inner bladder  10  of the liquid container  12  is drained via air valve  122 , meaning the air inside the inner bladder  10  of the liquid container  12  is completely exhausted. Meanwhile, the air injection into gas container  11  via the air valve  111  of the gas container  12  is stopped and the air valve  122  of the liquid container  12  is closed to completely seal the inner bladder  10  of the liquid container  12 . 
         [0034]    The inner bladder  10  of the liquid container  12  is completely filled with demanded amount of liquid or colloid in accordance with user&#39;s training need to obtain desired texture of punching at practice and change the texture of punching via changing the pressure of the gas container  11 , and thus result in better training effect. The liquid or colloid and air inside the inner bladder  10  all can be respectively exhausted via the water inlet set  121  on the liquid container  12  and the air valve  111  on the gas container  11 , thus the air-water punching bag structure is easier to be stored and moved. 
         [0035]    If the firmness of the air-water punching bag structure is desired to be increased, air can be injected into the inner bladder  10  of the liquid container  12  via the air valve  122  on the liquid container  12 . 
         [0036]    In addition, if the liquid of colloid inside the liquid container  12  is not filled all the way up, the liquid or colloid inside the liquid container  12  will jiggle when the air-water punching bag structure is punched with external force; therefore, the center of the air-water punching bag structure will be shifting. A user will have to additionally use his/her muscles in different parts of the body to obtain balance, and thus further train more small groups of muscles.
