The structure is simple and easy to prepare, and the space occupied is small. The jet air curtain has good uniformity, thereby achieving a better smoke collection effect.

[0037] In this embodiment, the pot body 100 is further provided with a second air outlet channel 130, and the second air outlet channel 130 is respectively connected to the air inlet channel 110 and the first air outlet channel 120, and the purified airflow is further divided into a first sub-purified airflow and a second sub-purified airflow flowing through the first air outlet channel 120 and the second air outlet channel 130 respectively. The first air outlet channel 120 guides the first sub-purified airflow to the opening area of ​​the pot body 100, and the second air outlet channel 130 guides the second sub-purified airflow to other areas outside the opening area of ​​the pot body 100.

[0038] In this embodiment, the pot body 100 is generally circular in shape, and the pot body 100 includes an outer ring portion 101 and an inner ring portion 102 that are nested with each other. Specifically, the pot body 100 further includes an annular bottom plate 103, the outer ring portion 101 is connected to the outer ring edge of the bottom plate 103, and the inner ring portion 102 is connected to the inner ring edge of the bottom plate 103 to form an annular opening area.

[0040] In this embodiment, the pot body 100 includes a partition wall 150 for separating the first air outlet channel 120 and the second air outlet channel 130. The partition wall 150 is provided with a diverter surface 151, and the diverter surface 151 is used to divert the purified airflow into a first sub-purified airflow and a second sub-purified airflow.

[0041] In this embodiment, the airflow rate V1 of the first sub-purification airflow and the airflow rate V2 of the second sub-purification airflow satisfy the following relationship:

[0042] (V1+V2)×5% <V1≤(V1+V2)×60%。

[0043] In this embodiment, the airflow rate V1 of the first sub-purified airflow can be obtained by detecting the airflow at the first air outlet 121 of the first air outlet channel 120 , and the airflow rate V2 of the second sub-purified airflow can be obtained by detecting the airflow at the second air outlet 131 of the second air outlet channel 130 .

[0044] In this embodiment, the purification mechanism 300 includes a filter assembly 310 and a centrifugal gas-liquid separator 320 arranged in sequence along the flow direction of the smoke. Figure 4The centrifugal gas-liquid separator 320 includes a driving assembly 321 and a centrifugal mesh disk 322. The centrifugal mesh disk 322 rotates under the drive of the driving assembly 321, so that the liquid droplets in the flue gas are thrown out along the radial direction of the centrifugal mesh disk 322 under the action of centrifugal force, and the gas in the flue gas flows along the axial direction of the centrifugal mesh disk 322. The centrifugal gas-liquid separator 320 separates the gas and liquid of the flue gas for separate filtration, thereby achieving a better filtering and purification effect.

[0045] In this embodiment, the centrifugal mesh disk 322 may also be covered with a filter (not shown in the figure), which can improve the interception efficiency of grease particles in the smoke.

[0046] In other embodiments, the inner ring portion 102 may also be provided with a water diversion groove (not shown in the figure) for guiding the droplets thrown out along the radial direction of the centrifugal mesh disk 322 to the outside of the purification mechanism 300 to prevent the droplets from entering the filter assembly 310 and affecting the filtering effect of the filter assembly 310.

[0047] See also Figure 5 In another specific embodiment, the centrifugal mesh disk may also include a first centrifugal mesh disk 323 and a second centrifugal mesh disk 324 coaxially spaced apart, and the first centrifugal mesh disk 323 and the second centrifugal mesh disk 324 are driven by a driving assembly (not shown in the figure) to rotate coaxially and in opposite directions.

[0048] Specifically, the driving assembly may include a motor and a gear assembly 325, the input end of the gear assembly 325 is connected to the driving end of the motor, and the first centrifugal mesh disk 323 and the second centrifugal mesh disk 324 are respectively connected to the two output ends of the gear assembly 325 to rotate coaxially and in opposite directions.

[0049] In this embodiment, the gear assembly 325 includes a first transmission shaft 3251 and a second transmission shaft 3252 coaxially nested, a first bevel gear 3253 sleeved on the first transmission shaft 3251, a second bevel gear 3254 sleeved on the second transmission shaft 3252, and a third bevel gear 3255 connected to the output end of the motor, wherein the conical tooth surfaces of the first bevel gear 3253 and the second bevel gear 3254 are arranged opposite to each other, and respectively mesh with the conical tooth surfaces of the third bevel gear 3255.

[0050] In this embodiment, by setting up two layers of centrifugal mesh disks, the grease particles in the flue gas can collide with the two layers of centrifugal mesh disks twice, thereby increasing the interception efficiency of the centrifugal mesh disks on the grease particles. Moreover, by making the two layers of centrifugal mesh disks rotate in opposite directions, air flow vortices in clockwise and counterclockwise directions can be generated, effectively increasing the residence time of grease particles in the flue gas airflow, thereby making them easier to intercept.

[0051] In other embodiments, more than one centrifugal mesh disk may be disposed on the first transmission shaft 3251 and the second transmission shaft 3252, which is not limited here.

[0052] See also Figure 6 In this embodiment, the filter assembly 310 includes a first filter 311, an adsorption particle layer 312 and a second filter 313 which are stacked in sequence along the flow direction of the smoke, wherein the adsorption particle layer 312 includes a plurality of adsorption particles (not shown in the figure) clamped between the first filter 311 and the second filter 313.

[0053] In this embodiment, the first filter screen 311 is a filter cotton, which can absorb droplets in the smoke and protect the adsorption particle layer 312. Since the cost of the filter cotton is low, it can be replaced frequently to improve the problem of the adsorption particle layer 312 being prone to mold after long-term use. Among them, the first filter screen 311 can also play a role in filtering the smoke.

[0054] In this embodiment, the adsorbent particles are activated carbon particles, which can adsorb grease particles in the flue gas and filter the flue gas. The use of activated carbon particles can improve the purification effect of the flue gas, and because of its low wind resistance, it can reduce the noise generated by the purification mechanism 300 and reduce the speed requirement of the fan 200.

[0055] In this embodiment, the second filter 313 is a metal filter or filter cotton, which can prevent the activated carbon particles from falling and further filter the smoke.

[0058] In this embodiment, the airflow rate of the first sub-purification airflow and the airflow rate of the second sub-purification airflow can be changed by adjusting the aperture size and the opening direction of the air outlet hole 160, so that the smoke purification system can achieve a better smoke collection effect.
