Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to an oil pot and a flavoring pot, especially to an oil and flavoring pot which could control discharge amount, know the real usage amount and could make the flavoring residue at the spout after use could not contaminate the pot body and other places. 
       BACKGROUND OF THE INVENTION 
       [0002]    Because the society is increasingly prosperity, requirement of delicious and healthy food is sequentially increased. Flavoring plays an important role in cooking delicious and healthy food, and especially, controlling the usage amount of the flavoring is more important. 
         [0003]    For containing liquid flavoring, various kinds of containers are provided in the market. An oil pot shown in  FIG. 11  has a spout formed on the pot body. When used, the liquid flavoring is poured out from the spout, but such pot could not control the usage amount of the liquid flavoring. Furthermore, after use, the liquid flavoring residues at the spout flows along the outer wall of the spout and further contaminate the pot body and other places. A suit of measuring spoon shown in  FIG. 10  ties spoons of different capacities together. When used, a suitable spoon is selected for containing the liquid flavoring and comparting the liquid flavoring by measuring scale. However, this spoon suit needs to be used by both hands. Although being carefully used, the flavoring in the spoon is either poured over or not enough, and therefore, could not control the usage amount. Furthermore, the spoon suit needs to be cleaned each time after being used, which complicates the usage of the spoon suit. A sprinkling pot being used as oil/flavoring pot is shown in  FIG. 12 . The sprinkling pot includes a liquid squeezing structure fixed on a pot body by a pot lid. When used, the liquid flavoring in the pot body is pressed and jet out by the liquid squeezing structure. Sometimes, the liquid squeezing structure may be operated by a press-and-release manner, and the flavoring may jet out in an impulse manner. However, the usage amount of the flavoring could not be controlled and the real usage amount could not be known. Furthermore, breakers caused by jet flow will contaminate nearby stuffs and places. Moreover, after use, the liquid flavoring residues at the spout flows along the outer wall of the spout and further contaminate the pot body and other places, and therefore complicates the usage.

         [0046]    Referring to  FIGS. 13-17 , operation of the present invention is described as below. 
         [0047]    The oil and flavoring pot is in an original state before use. Meanwhile, the pressing arm  31 , the piston rod  29  and the piston  26  are located at the highest point. The pump  18  of the liquid squeezing structure is filled with liquid flavoring. The inlet valve  21  and the outlet valve  24  are shut off. In the original state of the other embodiment, the pressing arm  31 , the piston rod sleeve  62 , the piston rod  29  and the piston  26  are located at the highest point. The pump  18  of the liquid squeezing structure is filled with liquid flavoring. The inlet valve  21  is shut off. The piston lower bevel  65  of the piston  26  intimately contacts with the cone frustum bevel  64  of the cone frustum  63 , and the piston rod inlet  56  is shut off. When used, the user firstly decides the target amount of the liquid flavoring according to practical situation and experience, and then holds up the pot and presses the pressing arm  31  by fingers of the hold hand, to drive the piston rod  29  and the piston  26  to push the liquid flavoring in the pump  18 . The pressed liquid flavoring opens the outlet valve  24  and flows into the measuring cup  4  through the outlet pipe  6 , the piston rod outlet  10 , the sleeve opening  27  and the pump lid exhausting cavity  44 . In the other embodiment, when used, the user presses the pressuring arm  31  to drive the piston rod sleeve  62  and the piston rod  29  to move downwardly. At the beginning, the piston  26  is pushed by the liquid flavoring in the pump  18  and does not move downwardly with the piston rod  29  until the piston rod sleeve bevel  61  of the piston rod sleeve  62  contacts with the piston upper bevel  66  and pushes the piston  26  to move downwardly and presses the liquid flavoring, meanwhile, the piston lower bevel  65  has left the cone frustum bevel  64 , and the piston rod inlet  56  has released and the pressed liquid flavoring flows into the measuring cup  4  through the inlet cutout  53 , the piston rod inlet  56 , the outlet pipe  6 , the piston rod outlet  10 , the piston rod sleeve outlet  59 , the sleeve opening  27 , and the pump lid exhausting cavity  44 . At this moment, the user could clearly know the flavoring amount at any time by reading the measuring scale  42  of the measuring cup  4 . When the flavoring amount reaches to the target amount, the pressing arm  31  is released so that the spring  28  pushes the piston  26 , the piston rod  29  and the pressing arm  31  upwardly, and the pressure in the inner cavity of the pump  18  turns into negative pressure, which causes the outlet valve  24  be closed and immediately stops the liquid flavoring from flowing into the measuring cup  4 . Meanwhile, the liquid flavoring in the pot opens the inlet valve  21  and is pumped into the pump  18 . When the piston  26 , the piston rod  29  and the pressing arm  31  turn back to its original position, the pump  18  is filled with the liquid flavoring. In the other embodiment, when releasing the pressing arm  31 , the spring  28  pushes the piston rod  29 , the piston rod sleeve  62  and the pressing arm  31  upwardly. At the beginning, because of the friction generated between the piston  26  and the inner wall of the pump  18 , the piston  26  does not move upwardly with the piston rod  29 , until the piston lower bevel  65  contacts with the cone frustum bevel  64 , meanwhile, the piston rod inlet  56  is closed, and the piston  26  moves upwardly with the cone frustum  63 , causes the pressure in the inner cavity of the pump  18  turn into negative pressure, and the liquid flavoring in the pot opens the inlet valve  21  and is pumped into the pump  18 . When the piston  26 , the piston rod  29 , the piston rod sleeve  62  and the pressing arm  31  turn back to its original position, the pump  18  is filled with the liquid flavoring. 
         [0048]    If the first time of operation could not make the amount reach to the target amount, the operation could be continuously performed until the amount reaches to the target amount, meanwhile, the pressing arm is released immediately and the liquid flavoring feeding is stopped immediately. Then, the liquid flavoring in the measuring cup  4  is poured out for use. After pouring out the liquid flavoring, the liquid residues at the spout  11  flows to the groove bottoms  15  of the grooves  12  along the outer wall of the spout  11 , and returns back to the measuring cup  4  through the cup slots  14 . 
         [0049]    Furthermore, the present invention is not limited by the forgoing embodiments, the oil pot and/or flavoring pot utilizing measuring cup to receive the liquid pressed out from the pot, and disposing measuring scale on the measuring cup to measure the volume of accepted liquid are in the range of the present invention. Besides, the measuring cup may be stepping shaped, or the liquid squeezing structure may be vapour-pressure type or electric pump type, or the groove may be pocket shaped to receive the residue liquid flown along the outer wall of the spout, and other structures such as guide pipe may be used to guide the liquid to the measuring cup or the pot cavity are embodiments of the present invention. 
         [0050]    While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
