Liquid lifting assembly for sucking liquid to higher place

Abstract

A liquid lifting assembly for sucking liquid to a higher place, comprises a suction portion having a body, check valves, a suction head, and a pressure tank; the body being formed by a plurality of tubes; a pressure end, a suction end and a releasing end being extended from the body; the suction end and the releasing end are installed with check valves; the pressure end of the body being communicated to a pressure tank; the pressure tank being a hollow tank with air therein; a first check valve being installed between the releasing end and the body; the suction end being connected to a suction head through a second check valve. In use, the suction device sucks the liquid to the body; and the liquid in the pressure tank will give a pressure to push the liquid to flow through the check valve to the releasing end.

1 . A liquid lifting assembly for sucking liquid to a higher place, comprising:
 a suction portion having a body, check valves, a suction head, and a pressure tank; the body being formed by a plurality of tubes which are connected by stub tubes; a pressure end, a suction end and a releasing end being extended from the body; the suction end and the releasing end are installed with check valves;   the pressure end of the body being communicated to a pressure tank; the pressure tank being a hollow tank with air therein;   a first check valve being installed between the releasing end and the body; the suction end being connected to a suction head through a second check valve; and   a suction device being installed in the suction head;   wherein in use, the suction head is placed in liquid; the suction device sucks the liquid to the body; when the liquid flows into the pressure tank, the air pressure in the pressure tank will increase to a saturation value; if liquid is further sucked into the body, the liquid in the pressure tank will give a pressure to push the liquid to flow through the check valve to the releasing end.   
   
   
       2 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 1 , wherein the suction head is a trumpet structure with a great outer end. 
   
   
       3 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 1 , wherein a suction device is installed in the suction head. 
   
   
       4 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 1 , further comprising: an extension portion; the releasing end is further connected to an extension portion; the extension portion is installed with a check valve; one end of the extension portion is connected to the body and another end of the extension portion is connected to a further pressure tank by using a stub tube. 
   
   
       5 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 4 , wherein a branch tube is extended from the extension portion; two ends of the branch tube are communicated to the extension portion. 
   
   
       6 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 5 , wherein the branch tube has an approximate U shape; and a switch is installed in the branch tube so that the branch tube can be used as a standby tube by controlling opening and closing operations of the branch tube. 
   
   
       7 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 4 , wherein the releasing end is connected to the extension portion with a distance of 7 to 12 meters between the body and the extension portion. 
   
   
       8 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 1 , wherein the extension portion is further connected to another extension portion. 
   
   
       9 . The liquid lifting assembly for sucking liquid to a higher place; comprising: an extension portion; the extension portion is installed with a check valve; one end of the extension portion is connected to the body and another end of the extension portion is connected to a pressure tank by using a stub tube. 
   
   
       10 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 9 , wherein a branch tube is extended from the extension portion; two ends of the branch tube are communicated to the extension portion. 
   
   
       11 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 10 , wherein the branch tube has an approximate U shape; and a switch is installed in the branch tube so that the branch tube can be used as a standby tube by controlling opening and closing operations of the branch tube. 
   
   
       12 . The liquid lifting assembly for sucking liquid to a higher place as claimed in  claim 9 , wherein the extension portion is further connected to another extension portion.
