[0067] Please refer to Figure 2 and Figure 9 In some embodiments, the first smoke collecting part 40 and the second smoke collecting part 50 each include:

[0068] a first flow guide plate 41, a second flow guide plate 42, a third flow guide plate 43, and a fourth flow guide plate 44.

[0069] The first flow guide plate 41 and the third flow guide plate 43 are arranged on both sides of the second flow guide plate 42, and the fourth flow guide plate 44 is connected with the first flow guide plate 41 and the third flow guide plate 43 respectively on both sides; wherein the fourth flow guide plate 44 forms a flue with the first flow guide plate 41, the second flow guide plate 42, and the third flow guide plate 43.

[0070] It can be understood that the first smoke collecting part 40 and the second smoke collecting part 50 are both composed of the first guide plate 41, the second guide plate 42, the third guide plate 43 and the fourth guide plate 44, wherein the first guide plate 41 and the third guide plate 43 are both arranged on the two sides of the second guide plate 42, so that the first guide plate 41, the second guide plate 42 and the third guide plate 43 form a guide groove, wherein the first guide plate 41 and the third guide plate 43 are both movably connected with the smoke cover, so that the first smoke collecting part 40 can be opened or closed, and after the first smoke collecting part 40 is installed on the smoke cover, the first guide plate 41, the second guide plate 42 and the third guide plate 43 form a flue with the smoke cover, and the oil fume enters the smoke cover through the flue to realize the collection of the oil fume.

[0072] Please refer to Figure 3 and Figure 9 In some embodiments, further comprising: a hinge 45 arranged on the first mounting port 21 and the second mounting port 31, the first smoke collecting part 40 is installed on the first mounting port 21 through the hinge 45, and the second smoke collecting part 50 is installed on the second mounting port 31 through the hinge 45.

[0073] It can be understood that the first smoke collecting part 40 is movably connected to the first mounting port 21 through the hinge 45, specifically, the first guide plate 41 and the third guide plate 43 in the first smoke collecting part 40 are respectively provided with the hinge 45, and the first guide plate 41 and the third guide plate 43 are connected with the first smoke cover 20 through the hinge 45, so that the rotation of the first smoke collecting part 40 in the first mounting port 21 is realized, so that the first smoke collecting part 40 is unfolded or closed under the drive of the first driving mechanism 60. The second smoke collecting part 50 is movably connected to the second mounting port 31 through the hinge 45, specifically, the first guide plate 41 and the third guide plate 43 in the second smoke collecting part 50 are respectively provided with the hinge 45, and the first guide plate 41 and the third guide plate 43 are connected with the second smoke cover 30 through the hinge 45, so that the rotation of the second smoke collecting part 50 in the second mounting port 31 is realized, so that the second smoke collecting part 50 is unfolded or closed under the drive of the second driving mechanism 70.

[0074] Please refer to Figure 3and Figure 10 and Figure 11 In some embodiments, the bottom of the first smoke cover 20 has a first bottom plate 22, and the bottom of the second smoke cover 30 has a second bottom plate 32.

[0075] When the first smoke collecting part 40 and the second smoke collecting part 50 are closed, the first bottom plate 22 forms a first included angle a with the fourth flow guide plate 44, and the second bottom plate 32 forms a second included angle b with the second smoke collecting part 50.

[0076] When the first smoke collecting part 40 and the second smoke collecting part 50 are opened, the first bottom plate 22 forms a third included angle c with the fourth flow guide plate 44, and the second bottom plate 32 forms a fourth included angle d with the second smoke collecting part 50.

[0077] It can be understood that the bottom of the first smoke cover 20 is provided with a first bottom plate 22, and the first bottom plate 22 is provided with a smoke inlet, through which the oil fume enters the first smoke cover 20 and is then discharged through the flue in the smoke machine frame 10, thereby realizing the collection and discharge of the oil fume. The second smoke cover 30 is the same.

[0078] When the first smoke collecting part 40 and the second smoke collecting part 50 are closed, the first smoke collecting part 40 is located above the first bottom plate 22, and the second smoke collecting part 50 is located above the second bottom plate 32; wherein the first bottom plate 22 and the fourth flow guide plate 44 form a first included angle a, and the second bottom plate 32 and the fourth flow guide plate 44 form a second included angle b, the angles of the first included angle a and the second included angle b are the same, and the first included angle a is taken as an example for description below.

[0079] The angle of the first included angle a is 20°-50°, and it can be 20°, 25°, 30°, 35°, 40°, 45°, 50° or other angles. The first included angle a affects the oil fume suction force corresponding to the first bottom plate 22 part of the first smoke cover 20 and the second smoke cover 30 in the closed state. Specifically, when the first smoke collecting part 40 and the second smoke collecting part 50 are closed, the larger the angle of the first included angle a, the larger the inclination angle of the fourth flow guide plate 44, which can increase the flow rate of the airflow, thereby improving the smoke intake efficiency of the smoke machine 100. The use scenario is when the amount of oil fume is small. Specifically, when the inclination angle is large, the airflow flow rate is fast, thereby generating a large negative pressure, which can enable the smoke machine 100 to suck as much oil fume as possible into the smoke machine 100 even when the amount of oil fume is small, thereby reducing the occurrence of oil fume escape.

[0080] When the first smoke collecting part 40 and the second smoke collecting part 50 are opened, the first smoke collecting part 40 is located above the first bottom plate 22, and the second smoke collecting part 50 is located above the second bottom plate 32; wherein the first bottom plate 22 and the fourth guide plate 44 form a third included angle c, the second bottom plate 32 and the fourth guide plate 44 form a fourth included angle d, the third included angle c and the fourth included angle d have the same angle, and the third included angle c is taken as an example for description below.

[0081] The third included angle c has an angle of 100°-160°, and can be 100°, 105°, 110°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160° or other angles.

[0082] The third included angle c affects the smoke collecting area of the first smoke collecting part 40 and the second smoke collecting part 50. Specifically, when the third included angle c is small, the distance between the first smoke collecting part 40 and the second smoke collecting part 50 and the first smoke collecting cover 20 and the second smoke collecting cover 30 is farther, so that the smoke collecting area of the range hood 100 is larger, and the larger smoke collecting area can effectively reduce the escape of oil fume.

[0083] When the third included angle c is large, the first smoke collecting part 40 and the second smoke collecting part 50 are relatively not fully unfolded, and the smoke collecting area is relatively small.

[0084] Specifically, when the first smoke collecting part 40 and the second smoke collecting part 50 are in the opened state, the first smoke collecting part 40 and the second smoke collecting part 50 are located outside the first smoke collecting cover 20 and the second smoke collecting cover 30, at this time, the fourth guide plate 44 is no longer located above the second bottom plate 32, the smoke duct corresponding to the second bottom plate 32 is fully opened, most of the oil fume can be discharged through the first smoke collecting cover 20 and the second smoke collecting cover 30, and the first smoke collecting part 40 and the second smoke collecting part 50 can absorb the surrounding diffused smoke, so that the smoke collecting area of the range hood 100 is increased to reduce the escape of oil fume, and the exhaust efficiency of the range hood 100 is improved.

[0085] Please refer to Figure 3 , Figure 5 and Figure 7 In some embodiments, the first driving mechanism 60 includes a first driving part 61, a first gear 62, a first rack 63, and a second rack 64.
