Problems solved by technology
Although some ventilators are equipped with a turbine box, the design of the internal air duct of the turbo box is too simple, and there are many problems in the cooperation between the turbine and the turbo box. The optimization of the air duct and the reduction of vibration are not well considered, resulting in the ventilator Vibration and noise are large, which will adversely affect the user's sleep and health

The invention provides a turbine box used for a breathing machine. The turbine box comprises an upper cover and a lower cover which are sequentially, detachably and fixedly arranged. A rubber base is disposed between the lower cover and the upper cover and used for installing a turbine so as to support the turbine, sponges are arranged between the rubber base and the lower cover body and between the rubber base and the inner wall of the upper cover body respectively, and an air duct used for lengthening circulation distance of air flow in the turbine box is designed in the rubber base. According to the turbine box of the structure, air flow surrounds the turbine and rotates by a circle by means of the air duct formed by the rubber base in the turbine box and then enters the turbine from a turbine air inlet, so the circulation distance of the air flow in the turbine box is greatly lengthened, circulation smoothness of the air flow is ensured, outward spreading of noise of the turbine is effectively reduced, and accordingly noise of the turbine during work is lower. Besides, the invention further provides the breathing machine provided with the turbine box.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a turbine box and a ventilator. Background technique [0002] At present, various types of ventilators have been widely used in hospitals. Ventilators mainly control their turbines through programs. When the turbines are running, they drive the flow of air to assist patients in breathing. [0003] Some ventilators currently in use are not provided with a turbine box separately, and the turbine is directly fixed on the base. Although some ventilators are equipped with a turbine box, the design of the internal air duct of the turbo box is too simple, and there are many problems in the cooperation between the turbine and the turbo box. The optimization of the air duct and the reduction of vibration are not well considered, resulting in the ventilator Vibration and noise are large, which will adversely affect the user's sleep and health. [0004] To sum up, how to provide a turbine...
