In the present embodiment, the fan assembly 10 includes a fan wheel 101 and a fan volute 102, the fan wheel 101 and the turbine 111 are vertically disposed, and the turbine 111 is connected to each other by a bearing housing and the fan volute 102.
It will be appreciated that the turbine 111 is connected to the drive shaft 112 and ultimately to the fan volute 102 via the bearing housing, which reduces drag on the movement of the turbine 111.
Referring to fig. 5 and 6, the transmission mechanism 121 includes a driving wheel 1211, a timing belt 1212 and a driven wheel 1213, a driving shaft 1214 of the driving wheel 1211 is connected to the transmission shaft 112 through a coupling, the timing belt 1212 is sleeved on the driven wheel 1213 and the driving wheel 1211 and configured to transmit power to the driven wheel 1213 to drive a driven shaft 1215 on the driven wheel 1213 to rotate along an axial direction thereof, and the driven shaft 1215 is connected to the blocking disc 122.
It is worth to be noted that, the transmission mechanism 121 is formed by a synchronous belt 1212, a driving wheel 1211 and a driven wheel 1213, which has the advantages of high transmission efficiency, stable transmission and low noise, and is beneficial to controlling the working noise of the household range hood and improving the use effect of the range hood.

Meanwhile, the cross section of the synchronous belt 1212 is a periodic trapezoidal (rectangular) tooth, which has good structural stability, so that the phenomenon of belt separation cannot occur easily during the operation process, thereby enhancing the use effect and the service life of the range hood.
Referring again to fig. 5, the coupling is an oldham coupling 113. It can be understood that the oldham coupling 113 is widely used in various occasions such as general machinery, hydraulic machinery, engineering machinery, metallurgical machinery, mining machinery, chemical machinery, etc., when it is assembled, it must ensure that the central lines of the two welding jaw bearing holes in the middle are on the same plane, the allowance of the central lines must not exceed 1 degree, the spline part should slide freely, and the joint should rotate flexibly.

The dynamic control method of the oil smoke dynamic blocking system is mainly embodied as follows: firstly, the rotary power of the oil smoke dynamic blocking disc is driven by the airflow generated by the fan, and the rotating speed of the rotary power can be dynamically changed along with the air quantity of the fan. When more oil smoke is generated in cooking, the range hood needs to be adjusted to a high gear, the air speed in the volute is accelerated along with the increase of the rotating speed of the impeller in the fan, and the oil smoke is generated according to a dynamic pressure equation
And F ═ NFan (Refresh Fan)As can be seen from the formulas E and S, the driving force acting on the fan blades of the kinetic energy recovery device increases exponentially, the torque generated by the kinetic energy recovery device increases accordingly, and the recovered torque is transmitted to the dynamic barrier disc through the transmission shaft 112; therefore, the rotating speed of the dynamic blocking disc is correspondingly increased along with the increase of the gear of the range hood, and the blocking strength on the oil smoke is improved; warp gaugeCalculate 20m3When the range hood with the air volume per minute works at the maximum gear, the dynamic shielding disc can be accelerated to be more than 800r/min only in a few seconds, and the dynamic blocking disc matched with the fine holes can shield most of grease droplets and partial PM10And PM2.5。
When less oil smoke is generated in the cooking process, the range hood only needs to work at a lower gear, the flow velocity of air flow in the volute is reduced, the rotating speed of the dynamic blocking disc is correspondingly reduced due to wind resistance and component friction resistance, the suction resistance to the smoke is reduced, the efficiency of the range hood for sucking the smoke is improved, and meanwhile, the noise and the abrasion of a mechanical mechanism during working are reduced. According to the test result and the formula, the air quantity is 20m3The lowest gear of the/min range hood can be maintained at least at 400m3And the cooking oil can meet the requirement of general low-oil smoke cooking. Therefore, the dynamic regulation of the oil smoke interception strength can be realized according to different working gears of the range hood without any additional power source and electric control device.
