Kind Code:
A1
Abstract:
A dual-pump liquid discharge container, which comprises an outer tube (10), an inner tube (20) and a pump core mechanism (30), wherein the outer tube (10) is provided with a first pump core communication port (11) and an inner tube embedding installation port (12), the top end of the inner tube (20) is provided with an embedding joint (21), the embedding joint (21) is in sealed connection with the inner tube embedding installation port (12), the embedding joint (21) is provided with a second pump core communication port (22), the pump core mechanism (30) comprises a pump core installation base (31), a first vacuum pump (32), a second vacuum pump (33) and a pressing head (34), wherein the pump core installation base (31) is detachably connected to the top end of the outer tube (10), the pump core installation base (31) is provided with a first pump core installation port (311) and a second pump core installation port (312), the first pump core installation port (311) corresponds to the first pump core communication port (11), the second pump core installation port (312) corresponds to the second pump core communication port (22), the pressing head (34) can be slidably connected to the pump core installation base (31), the pressing head (34) is provided with a first liquid discharge channel (341) and a second liquid discharge channel (342), the channel inlet of the first liquid discharge channel (341) is in sealed connection with the pump outlet of the first vacuum pump (32), the channel inlet of the second liquid discharge channel (342) is in sealed connection with the pump outlet of the second vacuum pump (33), and the channel outlet of the first liquid discharge channel (341) meets the channel outlet of the second liquid discharge channel (342) to form a liquid discharge port (343). The dual-pump liquid discharge container is easy to control the extruded amount of material in a hose, and can prevent the extruded and mixed material from being sucked back into the tube to cause material back-mixing.
