Abstract
The invention relates to a micro-flow pump which comprises a rigid frame, a main chamber, a secondary chamber, a swing rod, a pump diaphragm, an electromagnetic driving device and an outflow pipeline. The main chamber is used for loading liquid to be pumped, and the secondary chamber comprises a left half chamber and a right half chamber which are respectively used for loading different chemical substances; a rotating shaft on the swing rod is fixed on the rigid frame, and the swing rod is vertically arranged in the secondary cavity to separate the left half cavity from the right half cavity; the pump diaphragm is located between the main cavity and the secondary cavity and can deform under the action of pressure. The electromagnetic driving device is used for driving the swing rod to rotate; one end of the outflow pipeline is connected with the main cavity, the other end of the outflow pipeline is provided with an outflow pump opening, and the outflow pipeline is communicated with the outflow pipeline cavity. According to the technical scheme, the micro-flow pump is driven to work by ingeniously utilizing chemical reaction, and efficient and accurate fluid control is achieved.
