BACKGROUND OF INVENTION 
       [0001]    1. Field of Invention 
         [0002]    The present invention relates to a water-cleaner and, more particularly, to a portable direct current water-cleaner. 
         [0003]    2. Related Prior Art 
         [0004]    Disclosed in Taiwanese Patent Publication No. 564769 is a portable bottle-type water-filtering apparatus. The apparatus includes a bottle  50 , a cap  10  and a filter  20 . The bottle  50  is formed with a bottleneck  51 . The cap  10  includes a tube  12  and a socket  14 . The tube  12  includes a first section extended from a first side of the cap  10  and a second section extended from a second side of the cap  10 . The socket  14  is formed on the second side of the cap  10  around the second section of the tube  12 . The filter  20  includes a case and a filtering material  21  filled in the case. The case includes a sieve  23  at an end and an opening at an opposite end. A neck  22  is formed on the sieve  23  and fit in the socket  14 . A plug  25  is fit in the opening of the case. A plurality of apertures  251  is defined in the plug  25 . 
         [0005]    The above-mentioned portable bottle-type water-filtering apparatus contains a small amount of water. Therefore, it is not very helpful when it is used during camping in the wilds where water is scarce. A large water-filtering apparatus contains a large amount of water; however, it takes a lot of time for the large water-filtering apparatus to filter water, and this is inconvenient. 
         [0006]    The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art. 
       SUMMARY OF INVENTION 
       [0007]    According to the present invention, a portable direct current water-cleaner includes a tank for containing water, a pump installed in the tank for pumping the water, a filter installed in the tank for filtering the water and a valve installed in the tank and movable between a first mode for directing the water from the pump to the filter so that the pump makes the water travel through the filter fast and a second position for bypassing the filter. 
         [0008]    It is an advantage of the water-cleaner according to the present invention to clean water fast for using the pump to pump the water through the filter. 
         [0009]    It is another advantage of the water-cleaner according to the present invention to provide options of whether to clean the water or not. 
         [0010]    Other advantages and features of the present invention will become apparent from the following description referring to the drawings.

     DETAILED DESCRIPTION OF EMBODIMENTS 
       [0027]    Referring to  FIGS. 1 through 3 , there is shown a portable direct-current (“DC”) water-cleaner according to a first embodiment of the present invention is shown. The portable DC water-cleaner includes a tank  10 , a pump  20 , a filter  30  and a mode-switching device  40 . 
         [0028]    The tank  10  includes a water chamber  11  for containing a lot of water and a component chamber for containing the pump  20 , the filter  30  and the mode-switching device  40 . 
         [0029]    A pipe  21  is lead from the water chamber  11  into the component chamber and, more specifically, to the pump  20 . There is a pipe  22  lead from the pump  20  to the mode-switching device  40 . 
         [0030]    The mode-switching device  40  includes a panel  41  installed on the tank  10 . There is a regulator  42  installed on the panel  41 . The pipe  22  is lead to the regulator  42 . A valve  43  is connected to the regulator  42  through a pipe  44 , to the filter  30  through a pipe  45  and to an outlet element  47  through a pipe  46 . The outlet element  47  is installed on the panel  41 . The valve  43  includes a handle  48  operable for switching the valve  43  between a first mode and a second mode. In the first mode, the water is transmitted to the filter  30  through the pipe  45  so that the water can be directed to the outlet element  47  through a pipe  32 . In the second mode, the water is directly transmitted to the outlet element  47 , with the filter  30  bypassed. There is a switch  411  electrically connected to the pump  20 . The switch  411  is installed on the panel  41 . The switch  411  is operable for turning on and off the pump  20 . 
         [0031]    There is a provided a faucet or tap  50 . The faucet  50  can be connected to the outlet element  47  so that the water can be flown from the faucet  50 . 
         [0032]    Referring to  FIGS. 3 through 5 , there is shown a mode in which the water is cleaned before it is flown from the outlet element  47 . Water is contained in the water chamber  11  of the tank  10 . The switch  411  is operated to turn on the pump  20  to pump the water to the filter  30 . The hydraulic pressure of the water is regulated by the regulator  42 . The handle  48  is operated to switch the valve  43  to the first mode as shown in  FIG. 4 . Because of the pump  20 , the water travels through the filter  30  fast and flows from the outlet element  47 . The filter  30  may employ a reverse-osmosis technique or include active carbon for clearing the water. 
         [0033]    Referring to  FIGS. 6 through 8 , there is shown a mode in which the water is not cleaned. The handle  48  is operated to switch the valve  43  to the second mode as shown in  FIG. 7 . The water travels to the outlet element  47  from the valve  43  directly. Then, the water flows from the outlet element  47 . 
         [0034]    Referring to  FIGS. 9 and 10 , there is shown a portable DC water-cleaner according to a second embodiment of the present invention. The second embodiment is like the first embodiment except including two outlet elements  47 . One of the outlet elements  47  is connected to the filter  30  through the pipe  32  while the remaining outlet element  47  is connected to the valve  43  through the pipe  46 . 
         [0035]    Referring to  FIGS. 11 through 15 , there is shown a portable DC water-cleaner according to a third embodiment of the present invention. The third embodiment is like the first embodiment except that the pump  20  can be switched between three modes by operating the switch  411 . When the pump  20  is in the first mode, the portable DC water-cleaner is in a clearing mode. When the pump is in the second mode, the portable DC water-cleaner is in a spraying mode. When the pump is in the third mode, the portable DC water-cleaner is in an idle mode. 
         [0036]    Referring to  FIG. 12 , the portable DC water-cleaner is in the cleaning mode. The pump  20  pumps the water to the filter  30  from the water chamber  11  of the tank  10 . The water flows from the filter  30  through the outlet element  47 . 
         [0037]    Referring to  FIG. 13 , the portable DC water-cleaner is in the spraying mode. The pump  20  pumps the water to the outlet element  47  from the water chamber  11  of the tank  10  through the regulator  42 . The water flows from the filter  30  through the outlet element  47 . 
         [0038]    Referring to  FIG. 14 , there is a socket  412  installed on the panel  41 . There is a wire  413  including a first plug at a first end and second plug at a second end. The first plug is inserted in a socket connected to a power supply installed in a car while the second plug is inserted in the socket  412 . Electricity is transmitted to the portable DC water-cleaner from the power supply through the wire  413 . 
         [0039]    Referring to  FIG. 15 , there is shown a battery  60  for energizing the portable DC water-cleaner. 
         [0040]    There is a nozzle  70  connected to the outlet element  47  through a hose. The water can be sprayed from the nozzle  70 . 
         [0041]    The portable DC water-cleaner according to the present invention exhibits several advantages. Firstly, it cleans water fast for using the pump  20  to pump the water through the filter  30 . Secondly, it provides a stable stream of water for using the regulator  42  to regulating the hydraulic pressure of the water. Thirdly, it provides options of whether to clean the water or not. Fourthly, it provides a 2-in-1 design that incorporating cleaning and spraying modes. 
         [0042]    The present invention has been described through the illustration of the embodiments. Those skilled in the art can derive variations from the embodiments without departing from the scope of the present invention. Hence, the embodiments shall not limit the scope of the present invention defined in the claims.
