invention is described as below . 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 . 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 . 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 . 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 .
an oil and flavoring pot includes a pot body having a measuring cup and a handle . a liquid squeezing structure is disposed on a pot lid , and capacity value and a residue recycling structure is formed on a cup wall . the liquid squeezing structure could press the flavoring into the measuring cup by one time or sequence times , and the operation could stop at any time . the amount of the flavoring could be read at any time . when the amount reaches to target , the operation of the liquid squeezing structure could be stopped and the target amount of flavoring is obtained , therefore facilitating to control and know the feeding amount . after use , the residue liquid flows to the groove along wall of the spout , and flows into the measuring cup through the cup slot , therefore keep the pot body clean . furthermore , the pot is conveniently operated by a single hand .
