Pulse type fluid mixing diaphragm pump and mixing ratio design method thereof

Abstract

The invention relates to a pulse type fluid mixing diaphragm pump and a mixing proportion design method thereof, the pulse type fluid mixing diaphragm pump comprises a cover plate (11), a valve seat (12), a diaphragm seat (13) and a driving mechanism (14), diaphragms (30) of a plurality of diaphragm bags are uniformly distributed on the diaphragm seat (13), the driving mechanism (14) drives the diaphragms (30) to do circumferential reciprocating motion, the plurality of diaphragm bags sequentially compress and stretch the diaphragm bags to suck fluid, and the diaphragm bags are driven by the driving mechanism (14). The diaphragm valve is characterized in that the diaphragm (30) comprises more than one first diaphragm bag (301) used for sucking first fluid and more than one second diaphragm bag (302) used for sucking second fluid, and the cover plate (11) and the valve seat (12) are provided with clamping grooves which are matched and sealed to form an outlet channel cavity (21) and an inlet channel cavity (22). The integrated proportional pulse type fluid mixing and extracting function of the diaphragm pump is achieved.

Description

Technical field [0001] The present invention relates to a micro pump device, specifically to a micro diaphragm pump having a channel model structure that can be achieved with gas-liquid mixing, in particular a pulsed fluid mixing diaphragm pump and a mixing ratio design method thereof. Background [0002] Usually micro diaphragm pumps are used for the suction and transmission of fluids such as gases and liquids, and it is often necessary to mix the two fluids, especially for some cleaning and flushing products, pumping and transporting water or other liquids while needing to mix air in the liquid, or some foam pumps used in cleaning products that need to produce foam, need to be mixed with the air in the environment to produce more foam and achieve better cleaning results. At present, in many pulse cleaning equipment, the usual practice is to add a separate air pump to the water pump, in order to achieve the pulse mixing of air and water flushing function, while daily products i...

Problems solved by technology

At present, in many pulse cleaning equipment, the common practice is to add a separate air pump to the water pump to realize the pulse mixed washing function of air and water. However, daily products in daily life are increasingly required to be refined and miniaturized. Experience, it is very necessary to make integrated improvements to increase product use functions without increasing product volume and production costs

[0003] And, micro-diaphragm pumps are generally used in daily life, and in the suction and transmission process of the pump, there is usually a certain amount of noise interference, which greatly affects the experience of product quality in daily life. Therefore, reducing the noise effect of micro-pumps is currently a lot of micro pump needs
