Title:
PORTABLE PUMP BY WHICH LIQUID MAY BE HORIZONTALLY PRESSED OUT
Document Type and Number:
WIPO Patent Application WO/2019/095456
Kind Code:
A1
Abstract:
A portable pump by which a liquid may be horizontally pressed out, comprising a liquid storage container (1), a pump head (2) being provided at a side of the liquid storage container (1), and a liquid suction device that is connected to the pump head (2) being provided within the liquid storage container (1); the liquid suction device comprises a liquid suction chamber (3), a spring (4), a piston (5), and a liquid outlet pipe (6) that is connected to the pump head (2); the liquid suction chamber (3) is provided with a liquid inlet pipe (31) and a fixed end (124) of the spring (4), check valves (71, 72) being provided within the liquid outlet pipe (6) and the liquid inlet pipe (31); the piston (5) is sleeved with the liquid outlet pipe (6), and is provided with a through hole (51) that matches an opening of the liquid outlet pipe (6); an end of the spring (4) is fixed at the fixed end (124), while the other end is connected to the piston (5), and under the pressure of the pump head (2), the piston (5) is driven to be horizontally displaced in the liquid suction chamber (3); when the piston (5) is reset, liquid stored in the liquid storage container (1) is suctioned from the liquid inlet tube (31) into the liquid suction chamber (3); when the piston (5) is pressed, the liquid stored in the liquid suction chamber (3) is extruded into the liquid outlet pipe (6) and suctioned out of the pump head (2). The portable pump is improved to address the problem wherein a liquid leakage gap is present in a pressed liquid outlet structure for which a side is provided with a pump head (2); by ensuring the sealing properties thereof, a storage liquid is quantified to control output, improving a liquid output effect.
