Title:
INTELLIGENT PRESSURE-SENSITIVE CONTROL BREAST PUMP
Document Type and Number:
WIPO Patent Application WO/2023/212947
Kind Code:
A1
Abstract:
An intelligent pressure-sensitive control breast pump, comprising a body (1) and a collector. The body (1) comprises an upper body housing (1), a lower body housing (2), and a control system. The control system is arranged in an accommodating cavity formed by combining the upper body housing (1) and the lower body housing (2). The control system comprises a cross-shaped silicone tube (6), a 7-shaped silicone tube (7), a PCBA board (8), a 7-shaped joint (10), a straight-through joint (11), an electromagnetic valve (12), a vacuum pump (13) and a lithium battery (14). A positive electrode and a negative electrode of the lithium battery (14) are connected with the PCBA board (8) for powering the PCBA board (8). Positive electrodes and negative electrodes of the vacuum pump (13) and the electromagnetic valve (12) are also connected with the PCBA board (8), and working states of the vacuum pump (13) and the electromagnetic valve (12) are controlled by the PCBA board (8). A pressure sensor is arranged on the PCBA board. An air inlet nozzle of the vacuum pump (13) is connected with one end of the cross-shaped silicone tube (6), and an air valve nozzle of the electromagnetic valve (12) is connected with one end of the cross-shaped silicone tube (6). The vacuum pump (6) cooperates with the electromagnetic valve (12) for vacuumizing. The other two ends of the cross-shaped silicone tube (6) are respectively connected with the straight-through joint (11) and the 7-shaped joint (10). The straight-through joint (11) is connected with the collector.
