Technical Field

[0001] This utility model belongs to the technical field of negative pressure detection devices, and in particular relates to a negative pressure detection fixture for a duckbill valve. Background Technology

[0002] A breast pump contains a duckbill valve, which is usually made of silicone. This part is injection molded, and its sealing performance affects the negative pressure suction of the breast pump. Therefore, it must undergo a negative pressure testing process after production. To address this, we propose a tooling specifically designed for negative pressure testing of the duckbill valve. Utility Model Content

[0003] The purpose of this invention is to provide a negative pressure detection fixture for a duckbill valve to solve the problems mentioned in the background art.

[0004] In view of this, the present invention provides a negative pressure detection fixture for a duckbill valve, comprising:

[0005] The enclosure contains detection components.

[0007] A number of placement blocks are provided, and the placement blocks are disposed on the base and sealed to the base. The placement blocks have a through structure, and a duckbill valve is sealed and inserted into the placement block and communicates with the placement block.

[0008] An air outlet connector is located on the base and corresponds to and communicates with each placement block;

[0009] The vent connector is connected to the detection component to detect the sealing performance of the duckbill valve.

[0010] A further embodiment of this utility model is that the detection component includes a digital display, a solenoid valve, a negative pressure regulator, an air pipe connector, and an air inlet connector. An air pump is installed outside the box. The air pump is connected to the air pipe connector. The air outlet connector and the air inlet connector are connected. The air inlet connector is connected to the solenoid valve. The negative pressure regulator is connected to the air pipe connector. The solenoid valve is connected to the negative pressure regulator. The detection path is formed by the placement block, the air outlet connector, the air inlet connector, the solenoid valve, the negative pressure regulator, the air pipe connector, and the negative pressure pump connected in sequence. The digital display is connected to the detection path one by one.

[0011] A further embodiment of this utility model includes indicator lights, which are connected one-to-one with the detection channels.

[0012] A further embodiment of this utility model includes a control module, which is disposed inside the housing and is connected to the detection component.

[0013] A further embodiment of this utility model includes a socket, which is located inside the housing and connected to the control module.

[0016] The beneficial effects of this utility model are:

[0017] This fixture includes a housing containing the detection components, and a base on the outside. The base has multiple placement blocks and air outlet connectors, each connected to a placement block. During testing, a duckbill valve is inserted into a placement block. Multiple independent detection pathways are formed by sequentially connecting the placement blocks, air outlet connectors, air inlet connectors, solenoid valves, negative pressure gauges, air pipe connectors, and a negative pressure pump. Each detection pathway independently detects a corresponding duckbill valve. After the solenoid valve operates for a set time, pressure is maintained for a period. Each digital display shows the pressure value of a corresponding detection pathway. After the pressure maintenance period, if the pressure value on the digital display is within the set range, the indicator light for that detection pathway is green; otherwise, a red alarm is triggered. Each detection pathway operates independently without interference, improving detection efficiency and accuracy. Attached Figure Description
