Description
- The present invention is a CIP of application Ser. No. 14/312,575, filed Jun. 23, 2014, the entire contents of which are hereby incorporated by reference.
- A conventional pumping device includes a pumping rod connected with a piston. The pumping rod is pulled to suck fluid in from a fluid source and is pushed to discharge the fluid to another container. It is inconvenient to operate, and fluid may leak during moving the pumping device.
- Thus, a pumping device having different positions of inlet and outlet is provided in patent TW M280453. This device is able to suck fluid and discharge fluid continuously without moving the device. However, structure of this device is complicated, and positions of every component are crucial. In addition, this device is unable to be used when the container is dumped.
- Besides, the inlet and the outlet of the previous device are fixedly disposed on the device, and positions of the inlet and the outlet are fixed. In addition, the pumping device is difficult to clean.
- Patent publication US 2012/0097275 also shows a hand pump whose inlet and outlet having opposite check valves. However, the inlet and the outlet are both located at the bottom of the pump to be at the same height. The check valve at the outlet may be easily pushed downward because of the fluid even when the pump is not pressed. Thus, the fluid, especially the liquid, may leak undesirably.
- Patent publication US 2004/0228750 disclosed a pump whose inlet and the outlet are the same channel. That, the pump can not be used to suck liquid from this container and to pour the liquid into another container at the time continuously.
- The main object of the present invention is to provide a pumping device having two check valves in opposite directions to allow transport fluid continuously.
- To achieve the above and other objects, a pumping device of the present invention includes a pump and a connector.
- The pump includes a container, a piston, and a pumping rod. The container is formed with an insertion hole and a pressure-releasing hole at a top portion thereof. The piston is slidably disposed in the container. An end of the pumping rod is connected to the piston, and an opposite end of the pumping rod is inserted through the insertion hole to extend outward. The container is formed with an opening at a bottom portion thereof. The container has a first connecting portion around the opening.
- The connector has a cavity, an inlet channel, and an outlet channel. The inlet channel and the outlet channel communicate with the cavity respectively. The connector has a second connecting portion around an opening of the cavity. The second connecting portion is engaged with the first connecting portion so that the cavity communicates with the opening of the container. A first check valve is disposed in the inlet channel. The first check valve allows fluid flowing into the inlet channel from exterior but prohibits fluid flowing out from the inlet channel. The connector further has a second check valve disposed in the outlet channel. The second check valve allows fluid flowing out from the outlet channel but prohibits fluid flowing into the outlet channel from exterior.
- When the piston is moved toward the top portion of the container, fluid outside is pumped into the container via the inlet channel. When the piston is moved toward the bottom of the container, fluid in the container is discharged out via the outlet channel.
- Thereby, the present invention is adapted for sucking fluid in and pumping fluid out by pulling or pushing the pumping rod. In addition, the connector is detachably disposed on the pump so that other kinds of connector can be used to replace the original connector.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
-
FIG. 1 is a stereogram of the present invention; -
FIG. 2 is a partial breakdown drawing of the present invention; -
FIG. 3 is a profile of the present invention showing fluid flowing in; -
FIG. 4 is a profile of the present invention showing fluid flowing out. - Please refer to
FIG. 1 toFIG. 4 , the pumping device of the present invention includes apump 10 and aconnector 20. - The
pump 10 includes acontainer 11, apiston 12, and apumping rod 13. Thecontainer 11 is formed with aninsertion hole 111 and a pressure-releasinghole 112 at a top portion thereof. Thepiston 12 is slidably disposed in thecontainer 11. An end of thepumping rod 13 is connected with thepiston 12, and the other end of thepumping rod 13 extends out through theinsertion hole 111. Ahandgrip 131 is disposed on the end of thepumping rod 13 extending out. Thecontainer 11 has anopening 113 at a bottom portion thereof and a first connectingportion 114 around the opening 113. In the present embodiment the first connectingportion 114 includes external thread. Thecontainer 11 is made of transparent material and is formed with a capacity scale on the outer wall thereof. - The
connector 20 is independent and detachable from thepump 10. Theconnector 20 has acavity 21, aninlet channel 21, and anouter channel 23. Theinlet channel 22 and theoutlet channel 23 are independent to each other and communicate with thecavity 21 respectively. Theconnector 20 has a second connectingportion 211 to be engaged with the first connectingportion 114 to allow thecavity 21 communicating with the opening 113. In practice, the second connecting portion has internal threads to screw with the first connecting portion. In the present embodiment, aconverter 50 is provided. Theconverter 50 has aninternal thread portion 51 and anexternal thread portion 52. Theinternal thread portion 51 is adapted for being screwed with the first connectingportion 114, and theexternal thread portion 52 is adapted for being screwed with the second connectingportion 211 so as to link theconnector 20 and thepump 10 together. As a result, thepump 10 can be connected with theconnecter 20 even if the sizes of the first connectingportion 114 and the second connectingportion 211 does not fit each other. Theinlet channel 22 has a first check valve which only allows fluid flowing into theinlet channel 22 but prohibits fluid flowing out from theinlet channel 22. Theoutlet channel 23 has a second check valve which allows fluid flowing out from theoutlet channel 23 but prohibits fluid flowing into theoutlet channel 23 from exterior. In the present embodiment, asmaller entrance 24 is formed between theinlet channel 22 and exterior. The first check valve includes aslidable blocking element 221 which is pushed by aspring 222 so that the blockingelement 221 tends to block theentrance 24. Fluid outside is able to push theblocking element 221 to flow into theinlet channel 22. Asmaller exit 25 is formed between thecavity 21 and theoutlet channel 23. The second check valve includes aslidable blocking element 231 which is pushed by aspring 232 so that the blockingelement 231 tends to block theexit 25. Fluid in thecavity 21 is able to push theblocking element 231 to flow out via theoutlet channel 23. - When the pumping
rod 13 is pulled to move thepiston 12 toward the top portion of thecontainer 11, fluid outside is sucked into thecontainer 11 via theinlet channel 22. When the pumpingrod 13 is pushed to move thepiston 12 toward the bottom portion of thecontainer 11, fluid in thecontainer 11 is discharged via theoutlet channel 23. - In the present embodiment, the
inlet channel 22 is located at a bottom portion of theconnector 20 and is aligned vertically with thecavity 21. Theoutlet channel 23 is located at a lateral portion of theconnector 20 between thecavity 21 and theinlet channel 22 so that theoutlet channel 23 is higher than theinlet channel 22. Thereby, when the fluid in thecontainer 10 is pushed out, the fluid pushed the first check valve to ensure theentrance 24 is blocked by the blockingelement 221. In addition, when fluid outside flows into thecavity 21, the second check valve may not be pushed to open theexit 25. - In use, the
entrance 24 can be sleeved onto by apipe 30 or others to communicate with a fluid source, and theexit 23 can be connected with aquick coupling 40, a pipe, or others to communicate with a fluid collector. Thereby, when pulling the pumpingrod 13 to move thepiston 12 upward, fluid is sucked into thecontainer 11 via thepipe 30, theentrance 24, theinlet channel 22, and thecavity 21. Thereafter, when pushing the pumpingrod 13 downward, fluid in thecontainer 11 is pushed into thecavity 21, and the fluid further pushes the blockingelement 231 of the second check valve to open theexit 25. Thus, the fluid flows to the fluid collector via theoutlet channel 23 and thequick coupling 40. As a result, the present invention is able to be used for transporting fluid from one container to another container continuously. Besides, the connector can be replaced with other connectors, such as connectors having check valves in different positions. In addition, the connector is detachable so that the connector and the pump are easy to clean.
