Abstract

The invention discloses a fan and a ventilator. The fan comprises a first shell, a second shell and a rotor body, wherein the first shell is provided with a first air inlet; the second shell is fixedly connected with the first shell to form an accommodation cavity; the second shell is provided with multiple air supply holes; the rotor body is arranged in the accommodation cavity, and the accommodation cavity is divided into a first cavity body and a second cavity body; the rotor body is provided with a rotating shaft, and a first impeller is arranged at the first end, close to the first air inlet, of the rotating shaft; the rotor body further comprises a housing, and an airflow passage communicated with the multiple air supply holes is formed between the housing and the second shell. According to the fan, the second shell is provided with the multiple air supply holes, and by the multiple air supply holes, airflow can be effectively combed, thereby avoiding formation of turbulent flow and / or eddy current, making the airflow smoother and reducing running noise of the fan. The invention further provides the ventilator, which is provided with the fan provided by the invention. The ventilator has the characteristics of stable airflow and low running noise.

Description

technical field [0001] The present invention relates to the technical field of ventilators, and more specifically, to a blower and a ventilator including the blower. Background technique [0002] A ventilator is a medical device that uses a fan to generate power to replace, control or change the spontaneous breathing movement of the human body. As the main functional module of the home ventilator, the fan has a guiding influence on the performance and appearance of the home ventilator. The performance of the household ventilator, especially the appearance, should be designed around the direction of the output hole of the fan. [0003] At present, the power sources of the existing household ventilators all use blowers, however, the existing blowers all adopt the form of a single output hole. The output hole and the inlet hole of some fans are arranged in a tangential manner, and the output hole and the inlet hole of some fans are arranged in a coaxial direction. The form o...
