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, and the other is provided in the 2 nd concentric tube. The number of concentric tubes 11 of the present invention can be any positive integer, and the set of vortex generating devices 14 can be less than or equal to any positive integer number of concentric tubes 11.
The concentric tube 11 is formed by a line segment formed by a plurality of broken lines surrounding the middle axis for a circle, and the intersection position of two adjacent line segments on the inner wall of the concentric tube 11 is a vortex generation position 15, as shown in fig. 7. The shape of 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, thereby improving the efficiency of removing the oil smoke.
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 the end connected with the air draft assembly, namely the air outlet of the concentric tube 11, the other end of the concentric tube 11 is the air inlet of the concentric tube 11, and according to the venturi effect, the larger the area through which the fluid flows, the smaller the flow velocity is, namely, the velocity of one end of the gas concentric tube 11 is greater than that of the other end of the concentric tube 11. According to Bernoulli's law, the higher the speed of the gas, the lower the pressure, so that the pressure at the end of the concentric tube 11 connected with the air draft 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, so as to promote the oil smoke gas to enter, and improve the oil absorption effect.

The cigarette machine main part still is provided with oil collecting device 3 and convulsions subassembly, convulsions subassembly fixed mounting in the inside of shell 2 and be located the top of oil smoke separator 1, and oil collecting device 3 assembles in the bottom of shell 2, and shell 2 is spherical shell 2.
The eave structure 13 is provided with a plurality of through holes 131. The through holes 131 are used for gathering large oil particles when the oil fume separator 1 rotates, and the oil particles are separated from the inside of the oil fume separator 1, so that the separation effect of the oil fume particles is greatly improved.
The cleaning process of the range hood is as follows: after the lampblack absorber used a period of time, the user added the appropriate sanitizer to stock solution portion 51 and installed stock solution portion 51, pipe 52, pressed the portion 53, shower nozzle 54 and suction mechanism 55 well before cleaning device 5 used, pressed down to press the portion 53 with the sanitizer again to shower nozzle 54 through pipe 52 and spray to oil smoke separator 1 and reach clean inside oil stain effect.
The oil absorption process of the range hood is as follows: the range hood is opened, the motor 4 drives the oil smoke separator 1, the wind wheel of the air draft assembly rotates simultaneously, oil smoke particles are separated in seven layers in the range hood, and finally the oil smoke particles are discharged from an almost clean gas outlet, as shown in fig. 6. The seven-layer separation is specifically as follows:
first layer separation, inertial separation: lampblack enters the interior of the range hood 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 sudden change of the area of the shell air inlet 21, the air flow speed is accelerated, and the inertia momentum is relatively increased. And the oil smoke will form a very thin boundary layer around the ring-shaped sheet 22, and because the outer shell air inlet 21 of the outer shell 2 forms an included angle with the ring-shaped sheet 22, the oil smoke is forced to flow upwards and enter the oil smoke separator 1 after flowing downwards along the ring-shaped sheet 22, so that the heavier oil moves downwards separately from the crude oil smoke flow field in the downward inertial motion and is collected in the oil collecting device 3 at the bottom of the outer shell 2, and the first inertial separation is realized.
Second layer separation, vortex separation: the oil smoke particles separated by the first layer further generate flow field separation from the downward-upward flowing 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 a vortex. The flow field or the vortex flow and the adjacent flow field or the vortex flow are mutually influenced mutually, a continuously rotating flow field is formed on the annular sheet 22, and the rotating vortex flow reaches the maximum vortex quantity. The remaining light oil smoke will not stop at the rotating vortex accumulation of the ring-shaped sheet 22, and when a certain weight is accumulated, the flow field will not support the weight of the oil drop, and will fall downwards or flow along the ring-shaped sheet 22 to the oil collecting device 3.
Third layer separation, centrifugal separation: the rotation of the eave structure 13 following the concentric tubes 11 creates a centrifugal force that interacts with the attractive force of the wind wheel. After the second separation, the light oil smoke of remaining part contacts the outermost end of eaves portion structure 13 earlier and gets into concentric tube 11 again when getting into concentric tube 11, and the centrifugal force of eaves portion structure 13 outermost end can leave some fluid or oil smoke particle area or block and get into concentric tube 11 inside and move outward, throws away with higher tangential velocity again, and the particle of throwing away can fall at cyclic annular piece 22, flows to oil collecting device 3 along cyclic annular piece 22 at last.
Fourth layer separation, inertial separation and centrifugal separation: after the third layer of separation, the remaining oil smoke with lighter weight is simultaneously subjected to centrifugal force and attractive force, but the relative attractive force is greater than the centrifugal force. Some of the oil smoke will flow through the through holes 131 to the adjacent eaves 13, and due to inertia, the oil smoke and other oil smoke particles will be gathered into larger oil smoke particles and flow downward, and due to centrifugal force, the oil smoke particles will be thrown out at a higher tangential speed and finally flow along the ring-shaped pieces 22 to the oil collecting device 3.
Fifth layer separation, cyclonic centrifugal force and secondary vortex generation of concentric tubes 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 in the tube move towards the wall of the tube under the action of centrifugal force, the tube wall forms a high tangential velocity, and part of oil smoke is blocked from flowing upwards. In addition, the residual oil smoke can form vortex in the vortex generating device, and the vortex generating device does not stop rotating, so that the oil smoke is captured and cannot escape from the pipeline. After the attraction force and the centrifugal force are removed, the oil smoke which continuously rotates from the secondary vortex and moves at the pipe wall in a high tangent mode flows downwards along the inner pipe wall due to gravity and is collected to the oil collecting device 3.
The sixth layer is separated, the spoiler 111 is separated: the flow disturbing device 111 at one end of the concentric tube 11 generates flow field separation on the remaining oil smoke, and the flow field separation can block part of the oil smoke from flowing upwards and capturing the oil smoke by the vortex which does not rotate automatically due to the instability of the flow field.
Separating a seventh layer, and separating a wind wheel by centrifugal force: after the first six layers of separation, a small amount of very light oil smoke particles are left to be 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 outside through the air outlet.
This take clean function's lampblack absorber is provided with cigarette machine main part, can produce centrifugal force to separate oil smoke separator 1 and cleaning device 5 of oil smoke particle, and the detachable fixed mounting of cleaning device 5 is in the cigarette machine main part, and oil smoke separator 1 transmission is installed inside the cigarette machine main part. The range hood can easily clean the position with more oil stains in the range hood main body, does not need to be detached and cleaned by professionals every time of cleaning, and has the advantage of convenience in cleaning. The oil smoke separator 1 of the range hood with the cleaning function generates additional centrifugal force, can effectively remove oil smoke particles, and greatly improves the separation effect of the oil smoke particles.
