Description

TECHNICAL FIELD

[0001] The utility model relates to the peristaltic pump field, concretely to a multi-channel card type peristaltic pump that can release pump pipe integrally under non-working state. BACKGROUND

[0002] The peristaltic pump pumps fluid by alternately squeezing and releasing the elastic conveying hose of the pump. When the roller rolls the pump pipe, the pump pipe is compressed and negative pressure is generated, thereby allowing more fluid to enter. During operation, at least one roller compresses the pump pipe, thus having a self-locking cutoff function. The roller is directly rotated by the motor or the gear box, similar to squeezing the hose with two fingers. As the fingers move, negative pressure is formed in the pipe, and liquid flows accordingly.
