The third air inlets 122 are strip-shaped, and negative pressure can be generated at the third air inlets 122 when the smoke exhaust fan operates. When the oil fume flows to the top plate 12, the oil fume flowing forward between the first air inlets 111 and the second air inlets 121 can be sucked into the smoke collecting cavity 13 by the third air inlets 122 when flowing through the third air inlets 122, in this way, the escape of the oil fume can be further reduced, and the suction effect of the smoke machine on the oil fume can be further improved.
[0030] The smoke machine of the utility model, as shown in Figure 1 and Figure 2As shown, the top plate 12 is further provided with a fourth air inlet 123 between the two second air inlets 121, the number of the fourth air inlets 123 is two, the size of the two fourth air inlets 123 along the left-right direction of the top plate 12 is less than the size of the third air inlet 122 along the left-right direction of the top plate 12, the two fourth air inlets 123 are arranged close to the left end and the right end of the top plate 12 and are located at the rear side of the third air inlet 122. The fourth air inlet 123 is in a strip shape, and a negative pressure can be generated at the fourth air inlet 123 when the smoke exhaust fan is running. The length of the fourth air inlet 123 is less than that of the third air inlet 122, which is equivalent to increasing the air inlet area of the part corresponding to the left end of the top plate 12 and the part corresponding to the right end of the top plate 12 of the third air inlet 122. After the oil fume flows to the top plate 12, the oil fume flowing forward between the first air inlet 111 and the second air inlet 121 first flows through the fourth air inlet 123, part of the oil fume is sucked into the smoke collecting cavity 13 by the fourth air inlet 123, and the oil fume that cannot be sucked by the fourth air inlet 123 continues to flow forward and is finally sucked into the smoke collecting cavity 13 by the third air inlet 122. In this way, the escape of the oil fume can be further reduced, and the suction effect of the smoke machine on the oil fume can be further improved.
[0031] The smoke machine of the utility model, such as Figure 3 and Figure 4 As shown, the top plate 12 is provided with a cavity, the third air inlet 122 and the fourth air inlet 123 are arranged in the cavity, and the second air inlet 121 is arranged on the part of the top plate 12 located on both sides of the cavity. The cavity can play a gathering role on the oil fume flowing to the top plate 12, so as to increase the difficulty of the oil fume escaping from the top plate 12, prolong the time of the oil fume flowing along the top plate 12, and thus provide sufficient time for the third air inlet 122 and the fourth air inlet 123 to fully suck the oil fume into the smoke collecting cavity 13. The cavity is located between the two second air inlets 121, if the oil fume in the cavity flows out of the cavity from the left and right sides, the two second air inlets 121 can timely suck this part of oil fume into the smoke collecting cavity 13, so as to further reduce the escape of the oil fume.
[0032] In some embodiments, as shown in Figure 1 The number of the cavity is one, the number of the third air inlet 122 is one or two or more, one third air inlet 122 extends to the left and right sides of the cavity along the left-right direction of the cavity, the left side of the third air inlet 122 extends to the left end of the corresponding fourth air inlet 123, and the right side of the third air inlet 122 extends to the right end of the corresponding fourth air inlet 123; or, two or more third air inlets 122 are arranged along the left-right direction of the cavity, the left end of the leftmost third air inlet 122 extends to the left end of the corresponding fourth air inlet 123, and the right end of the rightmost third air inlet 122 extends to the right end of the corresponding fourth air inlet 123.

Since the length of the third air inlet 122 is greater than the length of the fourth air inlet 123, the ends of the two third air inlets 122 close to each other can be close to the middle of the mold cavity bottom plate. In this way, the appearance integrity of the smoke machine body 1 can be improved, and the distribution positions of the third air inlet 122 and the fourth air inlet 123 can be reasonably arranged to ensure that the oil fume flowing to the top plate 12 is fully sucked into the smoke collecting cavity 13.
[0035] In the smoke machine of the utility model, as shown in Figure 1 , the top plate 12 is further provided with an illumination window 124, the illumination window 124 is arranged on the front side wall surface of the mold cavity, the smoke machine body 1 further has an electric control cavity 14, the electric control cavity 14 is internally provided with an illuminating lamp 15, the illuminating lamp 15 is installed in the electric control cavity 14, and the illumination side of the illuminating lamp 15 is aligned with the illumination window 124.

[0036] In other embodiments, as shown in Figure 3 , the number of mold cavities is two, one third air inlet 122 and one fourth air inlet 123 are arranged in each mold cavity, the third air inlet 122 extends along the left-right direction of the mold cavity, and the fourth air inlet 123 is arranged close to the left side / right side of the left side / right side mold cavity and extends to the left side / right side of the third air inlet 122.
[0037] The two cavities are distributed along the width direction of the top plate 12, and the two cavities can be defined as a left cavity and a right cavity, the fourth air inlet in the left cavity is close to the left cavity wall of the left cavity, and the fourth air inlet in the right cavity is close to the right cavity wall of the right cavity. The left end of the fourth air inlet in the left cavity is flush with the left end of the third air inlet in the left cavity. The right end of the fourth air inlet in the right cavity is flush with the right end of the third air inlet in the right cavity. By setting the number of cavities to two, the oil fume can be divided when flowing to the top plate 12, so that the oil fume flow is not disturbed when the oil fume just contacts the top plate 12 and turns, so that the divided oil fume can be more timely and fully sucked into the third air inlet and the fourth air inlet in the two cavities.
[0038] In the above embodiment of the two cavities, as shown in Figure 3 The top plate 12 is further provided with an illumination window 124, the illumination window 124 is arranged between the two cavities, and the smoke machine body 1 further has an electric control cavity 14, the electric control cavity 14 is provided with an illumination lamp 15, the illumination lamp 15 is installed in the electric control cavity 14, and the illumination side of the illumination lamp 15 is opposite to the illumination window 124.

[0039] In the smoke machine of the utility model, as shown in Figure 2 and Figure 4 The first air inlet 111 is a hidden air inlet, the front panel 11 is provided with a gap, the lower edge of the gap extends into the smoke collecting cavity 13 and is provided with a shielding plate 16, the shielding plate 16 is inclined from bottom to top and rear, the height of the upper edge of the shielding plate 16 is not lower than the height of the upper edge of the gap, and the gap between the upper edge of the shielding plate 16 and the upper edge of the gap forms the first air inlet 111. The smoke machine of the utility model, the projection of the gap falls into the shielding plate 16, and when viewed from the front panel 11 on the user side, the user can see the shielding plate 16 and cannot see the back plate of the smoke collecting cavity 13 through the gap, so that the user cannot see the oil stains on the back plate of the smoke collecting cavity 13, the appearance of the smoke machine can be ensured, and the user experience can be improved.
[0040] In the smoke machine of the utility model, the shielding plate 16 extends from the lower edge of the gap to the inner side of the gap, the distance between the shielding plate 16 and the front panel 11 increases from the lower edge to the upper edge, the shielding plate 16 and the flow cross section of the gap form a flow channel, the flow channel communicates the gap and the first air inlet 111, the airflow flows into the gap first, hits the shielding plate 16, then flows to the first air inlet 111 along the flow channel, and then flows into the smoke collecting cavity 13 through the first air inlet 111.
[0041] When the user looks at the gap on the front panel 11, the shielding plate 16 can shield the user's view to prevent the user from directly seeing the back plate of the smoke collection cavity 13 through the gap, so as to avoid affecting the user's visual perception of the range hood. Since the shielding plate 16 is arranged in a downward and rearward inclined manner, a gap between the upper edge of the shielding plate 16 and the upper edge of the air inlet forms a hidden first air inlet 111. After the oil fume flows into the gap and hits the shielding plate 16, the oil fume can continue to flow into the smoke collection cavity 13 upward through the first air inlet 111, so that the shielding plate 16 does not affect the process of the oil fume flowing into the smoke collection cavity 13, and the oil fume suction effect of the range hood is ensured.

The number of the connecting plate 17 is two, and the two connecting plates 17 are arranged at the two ends of the shielding plate 16 respectively. Each connecting plate 17 connects the end side of the shielding plate 16 with the side edge of the gap. In this way, the shielding plate 16 and the front panel 11 can be connected as a whole in the visual perception, so as to improve the appearance integrity of the range hood. In addition, the connecting plate 17 can increase the connection position of the shielding plate 16 and the front panel 11, so as to improve the connection stability of the shielding plate 16 and the front panel 11. One side of the connecting plate 17 close to the gap is a concave arc surface, and the upper edge of the connecting plate 17 forms a concave arc edge. The spacing between the upper edge of the connecting plate 17 and the upper edge of the gap can be increased as much as possible, so as to increase the flow area of the first air inlet 111, and improve the air inlet amount of the first air inlet 111.
[0043] The shielding plate 16 and the connecting plate 17 are integrally formed with the front panel 11. The front panel 11 is a sheet metal part, and the shielding plate 16 and the connecting plate 17 are both cut and stamped on the front panel 11. The connecting position of the connecting plate 17, the front panel 11 and the shielding plate 16 is smoothly transitioned, so as to ensure the appearance of the front panel 11.
