Description:
BACKGROUND OF THE INVENTION 
       [0001]    a) Field of the Invention 
         [0002]    The present invention relates to a water supply base of a plant pot, and more particularly to water supply base of a plant pot, wherein the water supply base is provided with a holding space to contain liquid and liquid is supplied to soil in the plant pot through a porous rod. 
         [0003]    b) Description of the Prior Art 
         [0004]    Bonsai is able to increase greenery, suitable for landscaping and viewing. However, plant will be withered if water is not supplied for a long time; on the other hand, if too much water is supplied, water will easily escape or be accumulated in a water pan at a bottom of the plant pot, forming a hot bed for mosquito media. The Taiwan Utility Model Patent, No. M402603, “Water Pan and Plant Pot,” discloses a water pan and a plant pot, including a pan which is provided with a pan surface and a wall rim protruding along a periphery of the pan surface, with that a water-holding space is formed between the pan surface and the wall rim and the pan surface is provided with a fixing member; a porous rod which is assembled on the fixing member; and a pot which is assembled on the pan surface of the pan and maintains a gap from the pan surface, with that a bottom of the pan is provided with a through-hole sheathed with the porous rod, an interior of the pan is formed with a containing space and the through-hole is connected to the containing space. A user can put the porous rod upright on the fixing member, penetrating the porous rod through the through-hole to extend into the containing space. Next, soil and bonsai are planted into the containing space of the pot; and then, excessive water used for sprinkling the bonsai is recovered by the pan and reused by the capillary action of the porous rod, achieving an effect of saving water. 
         [0005]    Nevertheless, the abovementioned patent exists with following shortcomings: 
         [0006]    1. The excessive water for sprinkling the bonsai is recovered by the pan. But as the pan takes water in an open way, mosquito medial can be easily bred. 
         [0007]    2. The pan takes water in the open way; therefore, water can easily volatile by high ambient temperature and cannot be totally used for the bonsai. 
         [0008]    3. The excessive water that is used to sprinkle the bonsai can overflow from the pan, causing water to be accumulated on a ground or a desktop. 
         [0009]    Additionally, the Taiwan Utility Model Patent, No. M401979, “Moisture-Retaining Plant Pot,” discloses a moisture-retaining plant pot. The moisture-retaining plant pot is provided with a watertight outer pot and an interior of the outer pot is provided with a first space. An interior of the first space is also inserted with a watertight inner pot and a proper gap is kept between the inner pot and the outer pot to contain water. An interior of the inner pot is provided with a second space to contain plant and dirt. A wall of the inner pot is penetrated with at least one through-hole. The through-hole is inserted with a porous conductor which is protruded into the first space and the second space, keeping dirt humid for a long time by the capillary action resulted from the porous conductor. Besides, the Taiwan Utility Model Patent, No. M369027, “Plant Pot Reminding of Sprinkling Using a Moisture Sensitive Material,” discloses a plant pot that reminds of sprinkling using a moisture sensitive material. The plant pot includes an outer pot which is a watertight vessel, with that a wall of the outer pot is filled with a moisture sensitive material; and an inner pot which is made by a porous material and is put inside the outer pot, with that an eave of the inner pot is provided with a water flooding hole. Through the moisture sensitive material on the outer pot, water content of the porous inner pot can be aware of to remind a user of sprinkling the plant, thereby adjusting water of the plant in the plant pot. 
         [0010]    The abovementioned patents M401979 and M369027 have to fit with the inner pot of a fixed shape and size to achieve the expected effect, unable to be applied to a general plant pot.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0031]    Referring to  FIG. 1  and  FIG. 2 , a first embodiment of the present invention comprises a body  1  and a porous rod  2 . The first embodiment is further described in association with a plant pot  3 . The body  1  includes a non-open holding space  11  to store water or nutrition liquid with fertilizer. The so-called non-open holding space means that the holding space  11  can be roughly formed with a sealed state through shielding or covering by other elements. The body  1  is provided with a platform  12  to emplace the plant pot  3 . In the first embodiment, the platform  12  is provided with a through-hole  13 . 
         [0032]    In the first embodiment, the porous rod  2  is solid and a top end of the porous rod  2  is provided with a circular resist portion  21  that is protruded radially. The resist portion  21  is used to prohibit the porous rod  2  from penetrating through a round hole  31  at a bottom of the plant pot  3 , thereby forming a limiting function. The porous rod  2  passes through the round hole  31  at the bottom of the plant pot  3  and the through-hole  13  of the body  1 , extending into the holding space  11 . 
         [0033]    The abovementioned body  1  further includes a water flooding hole  15  and a cover  151  to seal the water flooding hole  15 , so that a user can add water conveniently from the water flooding hole  15  into the holding space  11  and seal the water flooding hole  15  with the cover  151  after adding the water. A plane height of the water flooding hole  15  is a little lower than that of the platform  12 , so that a condition of adding water can be watched from the water flooding hole  15 , preventing from adding too much water that the water will overflow from the through-hole  13 . The body  1  is provided in advance with an assembling port  161  for installing a water level indication unit  16 . The water level indication unit  16  includes an outer tube  162  and a ball  163 . The abovementioned assembling port  161  is connected to the holding space  11  of the body  1 ; whereas, the outer tube  162  is a transparent tube with a sealed top end and is tightly installed at the assembling port  161 . A joining place between the outer tube  162  and the assembling port  161  is provided with a leak-proof washer, is pasted with silicon, or is treated with other known leak-proof methods to prevent water from leaking out. The top end of the outer tube  162  can be provided additionally with tiny air vents (not shown in the drawings) to maintain balance between inner and outer pressure of the outer tube  162 . An interior of the outer tube  162  holds the ball  163  and the ball  163  is preferably of explicit color to show the water level in the holding space  11 . 
         [0034]    Referring to  FIGS. 1 to 4 , after adding water from the water flooding hole  15  into the holding space  11 , the water flooding hole  15  is sealed by the cover  151 . At this time, the ball  163  will ascend (as shown in  FIG. 3 ) to show the current water level in the holding space  11 ; whereas, as the porous rod  2  is extended into water to transport water into soil in the plant pot  3  by the capillary action, keeping soil humid for a long time. After a period of time, the water level in the holding space  11  drops down and the ball  163  descends accordingly to remind the user to supplement water in time, preventing plant that is grown in the plant pot  3  from being withered. 
         [0035]    In the abovementioned first embodiment, by using the cover  151  to seal the water flooding hole  15 , the porous rod  2  to shield the through-hole  13 , and the plant pot  3  to abut on the platform  12 , the holding space  11  of the body  1  forms a non-open state, which is able to effectively prevent water in the holding space  11  from evaporating and dissipating, thereby maintaining a longer time for supplying water. 
         [0036]    Besides, in the abovementioned first embodiment, the resist portion  21  of the porous rod  2  is in a circular shape. As the resist portion  21  is to prevent the porous rod  2  from escaping out of the plant pot  3 , the resist portion  21  can be also in other shapes, such as a transversal rod or a bump. 
         [0037]    A second embodiment of the present invention is shown in  FIG. 5 . The second embodiment is also provided with a body  1 A, a holding space  11 A, a platform  12 A, a cover  151 A, an assembling port  161 A, an outer tube  162 A, a ball  163 A and a porous rod  2 A, and is implemented along with a plant pot  3 A. Most structures are the same as those of the abovementioned first embodiment; therefore, no further description is disclosed. In the second embodiment, the porous rod  2 A is not provided with the abovementioned resist portion, and the holding space  11 A is provided with a fixing seat  14 A at a bottom corresponding to the through-hole  13 A; whereas, a bottom of the porous rod  2 A is provided with a fixing slot  141 A corresponding to the fixing seat  14 A. By assembling the fixing seat  14 A with the fixing slot  141 A, the porous rod  2 A can be fixed without being pulled away when the plant pot  3 A is taken away. The fixing seat  14 A can be assembled with the fixing slot  141 A by other ways, not limited to that described in the second embodiment. 
         [0038]    A third embodiment of the present invention is shown in  FIG. 6 . The third embodiment is also provided with a body  1 B, a holding space  11 B, a platform  12 B, a cover  151 B, an assembling port  161 B, an outer tube  162 B, a ball  163 B and a porous rod  2 B and is implemented along with a plant pot  3 B.
