The through holes 131 have the function of separating oil particles which are converged into large particles from the inside of the oil smoke separator 1 when the oil smoke separator 1 rotates, so that the separation effect of the oil smoke particles is greatly improved.

Each vortex generating device group 14 consists of one or more vortex generating sub-devices located at the same eave structure 13. The vortex generating device group 14 of the present invention is used for generating vortex of oil smoke gas, thereby improving the oil removal capability.
The vortex generating device groups 14 are provided with m, wherein m is any positive integer greater than 0, and the m vortex generating device groups 14 are respectively fixedly installed on the outer surfaces of the concentric tubes 11 and encircle the connection positions of the eave part structures 13 and the concentric tubes 11.
N=3 in this embodiment, i.e. the concentric tubes 11 of this embodiment are provided with 3. In this embodiment m=2, that is, the vortex generating device group 14 is provided in 2, one is provided in the 3 rd concentric tube 11, and the other is provided in the 2 nd concentric tube.

The concentric tube 11 of the invention has the function of enabling the oil smoke gas to generate vortex on the inner wall of the concentric tube 11 and improving the oil smoke removing efficiency.
The diameter of one end of the concentric tube 11 is larger than the diameter of the other end. One end of the concentric tube 11 is connected with the air exhausting assembly, namely an air outlet of the concentric tube 11, the other end of the concentric tube 11 is an air inlet of the concentric tube 11, and according to the Venturi effect, the larger the area of fluid flowing through is, the smaller the flow velocity is, namely the velocity of one end of the gas concentric tube 11 is larger than the velocity of the other end of the concentric tube 11. According to Bernoulli's law, the higher the speed of the gas, the smaller the pressure, so that the pressure at one end of the concentric tube 11 connected with the exhaust assembly is high, and the pressure at the air inlet of the concentric tube 11 is low, thereby increasing the pressure difference between the air inlet of the concentric tube 11 and the external environment, and further promoting the entry of the oil smoke gas and improving the oil absorption effect.

The main body of the smoke machine is provided with a shell 2, the smoke separator 1 is arranged in the shell 2 in a transmission way, the shell 2 is provided with a plurality of shell air inlets 21 and annular sheets 22 matched with the shell air inlets 21, the annular sheets 22 are integrally connected with the corresponding inner surfaces of the shell 2 and are in one-to-one correspondence with edges of the shell air inlets 21, the annular sheets 22 of the invention can be fixedly arranged in the shell, and the specific implementation mode depends on implementation cases.
The annular piece 22 has the function of generating vortex when the oil smoke gas enters the shell 2, and simultaneously preventing oil smoke particles from being thrown out of an external space from the shell air inlet 21 of the shell when the oil smoke particles are thrown out of the oil smoke separator 1.
The working principle of the range hood is as follows: starting the range hood, driving the oil smoke separator 1 by the motor 4, simultaneously rotating the wind wheel of the air draft assembly, separating oil smoke particles in the range hood through seven layers, and finally discharging almost clean gas through the air outlet. The seven layers are separated as follows:
first layer separation, inertial separation: the oil smoke enters the interior of the smoke machine through the shell air inlet 21 of the shell 2, and enters the annular sheet 22 after entering the shell air inlet 21, because of the pressure difference between the interior of the shell 2 and the external environment and the abrupt change of the area of the shell air inlet 21, the air flow speed is increased, and the inertia momentum is relatively increased. The oil smoke forms a very thin boundary layer around the annular sheet 22, and because the shell air inlet 21 of the shell 2 forms an included angle with the annular sheet 22, the oil smoke is forced to flow downwards along the annular sheet 22 and then upwards to enter the oil smoke separator 1, so that heavier oil moves downwards in a downward inertial motion separately from a crude oil smoke flow field to be collected in the oil collecting device 3 at the bottom of the shell 2, and the first inertial separation is realized.
Second layer separation, vortex separation: the oil smoke particles separated by the first layer are further subjected to flow field separation in the downward-upward flow in the direction of the annular sheet 22, and the oil smoke particles cause an unstable flow field under the flow field separation to further form vortex. The flow field or vortex interacts with adjacent flow fields or vortices to form a continuously self-rotating flow field in the annular sheet 22, where the rotating vortices reach a maximum vorticity. The remaining light oil smoke will accumulate in the whirling vortex of the annular plate 22, and when a certain weight is accumulated, the flow field will not support the weight of the oil drops, and will drop down or flow to the oil collecting device 3 along the annular plate 22.
Third layer separation, centrifugal force separation: the eave structure 13 follows the rotation of the concentric tube 11 to create a centrifugal force that interacts with the attractive force of the wind wheel. After the second separation, the rest part of the lighter oil smoke contacts the outermost end of the eave structure 13 before entering the concentric tube 11 when entering the concentric tube 11, and the centrifugal force at the outermost end of the eave structure 13 can bring or block part of fluid or oil smoke particles into the concentric tube 11 and move outwards, and then the oil smoke particles are thrown out at a higher tangential speed, and the thrown out particles can fall on the annular sheet 22 and finally flow to the oil collecting device 3 along the annular sheet 22.
Fourth layer separation, inertial separation and centrifugal force separation: after separation by the third layer, the remaining lighter-weight soot is subjected to both centrifugal and attractive forces, but the relative attractive force is greater than the centrifugal force. Some of these soot flows through the through holes 131 to the adjacent eave structure 13, and due to the inertia effect, the soot and other soot or soot particles are collected into larger soot particles, which flow downward, and due to the centrifugal force effect, the soot particles are thrown out at a higher tangential velocity and finally flow along the annular sheet 22 to the oil collecting device 3.
Fifth layer separation, cyclonic centrifugal force and secondary vortex generation of concentric tube 11: the inner wall of the concentric tube 11 rotates to form a cyclone, the concentric tube 11 is a low-pressure area, fluid or particles and the like in the pipeline move towards the wall of the pipeline under the action of centrifugal force, the wall of the pipeline forms high tangential velocity, and part of oil smoke is blocked from flowing upwards. In addition, the rest oil smoke can form vortex in the vortex generating device, the vortex generating device continuously rotates automatically, and the oil smoke is captured and cannot escape from the pipeline. When the attractive force and the centrifugal force are removed, the secondary vortex which continuously rotates and the oil smoke which performs high tangential motion on the pipe wall can flow downwards along the inner pipe wall due to gravity and be collected to the oil collecting device 3.
Sixth layer separation, spoiler 111 separation: the flow field separation is carried out on the residual oil smoke by the turbulence device 111 at one end of the concentric tube 11, and part of the oil smoke is blocked from flowing upwards and being self-rotated due to the instability of the flow field by virtue of the flow field separation to capture the oil smoke.
Seventh layer separation, wind wheel centrifugal force separation: after the first six layers of separation, a small amount of very light oil smoke particles are remained and sucked into the wind wheel of the air draft assembly due to pressure difference, the rotating wind wheel forms centrifugal force to throw the remaining small amount of oil smoke particles onto the inner wall of the fan, and finally nearly clean gas is discharged out through the gas outlet.
This lampblack absorber of visual oil collecting device 3 in area can observe the grease and collect the condition, avoids grease to spill over oil collecting device 3 and brings clean trouble. Meanwhile, compared with the oil smoke separator 1 of the oil smoke machine in the prior art, the oil smoke machine with the visual oil collecting device 3 can generate additional centrifugal force, can effectively remove oil smoke particles, prevents the oil smoke particles from entering the air draft assembly, and greatly improves the separation effect of the oil smoke particles. Meanwhile, the range hood can avoid contact between air containing oil smoke particles and the wind wheel, and can effectively remove the oil smoke particles in the range hood.

The range hood with scales for the oil collecting device has other characteristics the same as those of the embodiment 1, except that: the oil collecting device 3 is provided with a volumetric graduated scale of volume, which comprises 50ml, 100ml, 150ml, 200ml, 250ml and 2L. It should be noted that, only the requirement of volumetric measurement can be satisfied, and any other volumetric scale value is within the protection of the present application, and no theory is given here.

Compared with the embodiment 1, the range hood with the scales of the oil collecting device has the advantages that one concentric tube 11 is increased, namely, the space volume of the oil smoke separator 1 in the shell 2 is increased, so that the area of an air inlet of the concentric tube 11 is reduced, the air inlet speed is increased, the pressure difference between the inner space and the outer space of the concentric tube 11 is increased, and the separation rate of oil smoke particles can be increased.
