Compatible mechanism for pumping liquid and exhausting air

Abstract

The invention relates to a compatible mechanism for pumping liquid and exhausting air. A motor 1 is electrified to rotate so as to drive a motor gear 15 and drive a planetary gear 25 to roll along an outer gear ring 2, drive a planet carrier 24 to rotate, drive a planetary gear 25A to roll along the outer gear ring 2, drive a planet carrier 24A to rotate, and drive an eccentric crank shaft 19 to rotate, so that thrust for a sliding connecting piece 20 is formed through conversion to push, pull and compress a capsule; four working processes of stretching, air inflow (liquid feed), compressing, and air outflow (liquid discharge) are generated; and an air inlet (liquid inlet) or an air outlet (liquid outlet) of each working station is communicated with an inlet or an outlet of a shell 5 through a diversion trench on a diversion trench transition piece 7. According to the invention, a water outlet working station is adjusted through increasing or decreasing sealing capsules 18, or the rotating speed of the eccentric crank shaft 19 is adjusted through adjusting the stage number of a planetary retarding mechanism, so that the compressing speed is adjusted, and the liquid outlet volume (air outlet volume) is adjusted. The compatible mechanism for pumping the liquid and exhausting the air is commonly used in fields of medical treatment, scientific research and the like, and various occasions such as water sampling analysis, a high-grade coffee machine and the like; and the working media can be air and liquid.

Description

Technical field: [0001] The invention relates to a mechanism compatible with liquid and gas pumping, especially in cooperation with a one-way valve to compress the gas or liquid in the compressed capsule to generate underpressure to achieve the purpose of pumping liquid and gas. The working medium can be gas or liquid (not oil and no strong corrosion, no particles, etc.). technical background: [0002] A mechanism that is compatible with pumping liquid and air. It is commonly used in medical, scientific research, laboratory, environmental protection and other industries. Its specific applications include: water sampling analysis, water circulation, water lifting, high-end coffee machines and other occasions. These forms The water pump has a large volume and a relatively high height. It is very inflexible and inconvenient to adjust in the case of variable flow requirements, and the range of flow adjustment is not large enough, especially in the case of low power and small vol...

[0002] A mechanism that is compatible with pumping liquid and air. It is commonly used in medical, scientific research, laboratory, environmental protection and other industries. Its specific applications include: water sampling analysis, water circulation, water lifting, high-end coffee machines and other occasions. These forms The water pump has a large volume and a relatively high height. It is very inflexible and inconvenient to adjust in the case of variable flow requirements, and the range of flow adjustment is not large enough, especially in the case of low power and small volume. In the case of low voltage, the output flow is small, and the adaptability of the product to the environment is small. For example, the working temperature is generally at room temperature, without self-priming function. Manually add "water diversion" before use, and do not run without water for a long time. The ability is not strong enough: the exhaust (water) end generally cannot carry a large load and cannot be blocked, so the general similar products on the market are not suitable for adjustable output flow, low power, small volume, and low voltage Large output flow under certain conditions, high temperature resistance type, can run without water for a long time, with self-priming function, strong load capacity: the exhaust (water) end can carry a large load, and can be used in a blocked device
