The utility model belongs to an electromechanical integration system, which relates to a vacuum generating device used for a medical biochemistry analyzer. The utility model is composed of a casing 2-1, a pressure sensing connecting pipe 2-2, a vacuum pump 2-3, a pressure sensor 2-4, an air inlet pipe 2-5, a screw 2-6, a bracket 2-7, a sealing plug 2-8, an end plate 2-9, a liquid level sensor 2-10, a vacuum cavity cylinder 2-11, a partition plate 2-12, and a rear sealing plug 2-13. The utility model has the advantages that the liquid level sensor is used for detecting liquid level, the partition plate is used for correspondingly increase a vacuum cavity body, and the purposes of controlling the liquid level in the vacuum cavity body, increasing using space, and effectively protecting the vacuum pump can be achieved. The utility model provides a vacuum generating device which can send alarm and can increase the useful space. The utility model can be used for a large medical biochemistry analyzer and becomes an indispensable instrument that large and medium hospitals carry out diagnosis for the illness state of patients, and the utility model can also be used for biological engineering, pharmaceutical engineering, etc.
