Document Type and Number:
WIPO Patent Application WO/2023/035295
Kind Code:
A1
Abstract:
The present invention relates to the technical field of air pumps, and in particular, to a mechanical air pump, comprising a driving mechanism, a gas generator, and a flow accelerator. The driving mechanism is provided with a housing, there being a cavity within the housing, and an outer wall of the housing being provided with an air inlet and an air outlet in communication with the cavity. Both the gas generator and the flow accelerator are mounted in the cavity, and the driving mechanism drives the gas generator and the flow accelerator to operate. The gas generator sucks an outside gas from the air inlet into the cavity, and the flow accelerator accelerates the gas in the cavity to form a high-speed, high-pressure gas, and outputs same from the air outlet. The mechanical air pump has advantages in operation such as having high gas flow output, high output air pressure, low noise, low vibration, low abrasion, and long service life.
