The invention discloses an airflow driving method for a hole-shaft fan. The hole-shaft fan comprises a front mesh enclosure, fan blades, a main body, a motor and a bearing. The air flow driving methodcomprises the following steps: a fan blade positioning step: arranging fan blade through holes in the middle parts of the fan blades, arranging blades at one end of each of the fan blades, arranginga transmission position at the other ends of the fan blades, and arranging the bearing on the inner side of the transmission position, wherein the bearing is fixedly connected with a bearing positioning part, a bearing positioning pipe fitting is arranged on the inner side of the transmission position, the bearing positioning pipe fitting is arranged on the inner side of the air inlet space of themain body, a bearing is arranged on the periphery of the bearing positioning pipe fitting, and the bearing positioning pipe fitting is arranged on the main body; a transmission step: arranging a belt, a motor and a transmission gear on the main body, wherein the belt drives the transmission position to decelerate and rotate, one end of the belt is arranged in a groove of the transmission position, and the other end penetrates through a belt through hole to be in limiting connection with the transmission gear; and an airflow flowing step: forming fan blade through holes in the middles of the fan blades, wherein peripheral airflow is generated by peripheral blades of the fan blades to drive the central airflow through holes to flow in the same direction, and airflow flow exchange is furtherimproved.
Description
technical field [0001] The invention relates to a fan, especially a method for driving an airflow by a hole shaft fan. Background technique [0002] The fan is one of the commonly used cooling and stirring air. It is used to flow the air, and at the same time it can be used as a cooling effect. It has the characteristics of fast cooling and convenient use; [0003] The fans on the market are all set to stir the air at the side and the periphery, the air in the middle is static, the airflow flows in a conical shape, and the vortex of the airflow cannot flow in parallel, so it is necessary to make further improvement and perfection. Contents of the invention [0004] The object of the present invention is to provide a hole shaft fan with simple and reasonable structure, safe and reliable, large air flow area and good effect, so as to overcome the shortcomings in the prior art. [0005] A method for driving airflow by a hole-axis fan designed for this purpose, wherein the ho...
