The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0041] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0042] Next, refer to Figures 1-8 to describe the smoke machine according to an embodiment of the present utility model. As Figures 1-4 shown, the smoke machine according to an embodiment of the present utility model includes:

[0043] A smoke machine main body 1. Specifically, the smoke machine main body 1 has a suction panel 11. Further, a suction port 111 is provided on the suction panel 11. The suction port 111 includes a normally closed suction port 1111 and a normally open suction port 1112. The normally open suction port 1112 is located above the normally closed suction port 1111. For example, in a specific embodiment, when the amount of smoke in the kitchen is small, only the normally open suction port 1112 can work to suck away the smoke, so as to ensure the cleanliness of the kitchen air. When the amount of smoke in the kitchen increases, the normally closed suction port 1111 and the normally open suction port 1112 can work simultaneously, so as to increase the suction area of the suction port by adjustment, and achieve an ideal smoke exhaust effect while saving energy.

[0044] A baffle 2. Further, the baffle 2 is slidably connected to the front side of the suction panel 11 and blocks the normally closed suction port 1111; it is used to open or close some or all of the normally closed suction ports 1111. For example, in a specific embodiment, when the normally open suction port 1112 is working properly and the amount of smoke in the kitchen increases, the normally closed suction port 1111 can be opened to suck away the excess smoke. Further, according to the degree of reduction of the amount of smoke, the normally closed suction port 1111 can be adjusted to be partially closed or fully closed, and thus the suction area of the suction port can be adjusted more flexibly according to the amount of smoke in the kitchen, so as to achieve an ideal smoke exhaust effect while saving energy, and improve the health level of the cooking personnel while ensuring the cleanliness of the air in the kitchen.

[0045] The movable panel 3 is further slidably connected to the front side of the air suction panel 11 and covers the baffle 2, and is used to open or close the air suction port 111. For example, in a specific embodiment, when a cooking person generates fumes while cooking in the kitchen, the movable panel 3 can be controlled to open, so that the air suction port 111 is opened, and then the normally open air suction port 1112 enters the working state, while the normally closed air suction port 1111 is flexibly adjusted to open or close according to the amount of fumes. When cooking is finished, the air suction port 111 stops working. At this time, the movable panel 3 covers the air suction port 111 and the baffle 2, thus ensuring the aesthetics of the range hood. Further, the part of the air suction port 111 exposed from the rear side of the movable panel 3 forms an effective air suction port. In this way, through the effective air suction port formed by the air suction port 111 behind the movable panel 3, the fumes in the kitchen can be absorbed, thereby improving the cleanliness of the air in the kitchen and ensuring the health level of the cooking person. Further, the air suction area of the effective air suction port is not less than the air suction area of the normally open air suction port 1112.

[0046] The driving module, its driving end is connected to the baffle 2 and the movable panel 3. For example, in a specific embodiment, the air suction area of the effective air suction port can be equal to the air suction area of the normally open air suction port 1112. In another specific embodiment, the effective air suction port can be the normally open air suction port 1112 and part of the normally closed air suction port 1111, that is, the air suction area of the effective air suction port can be equal to the air suction area of the normally open air suction port 1112 plus the air suction area of part of the normally closed air suction port 1111. In this way, by adjusting the air suction areas of the normally open air suction port 1112 and the normally closed air suction port 1111, that is, without increasing the rotation speed of the exhaust fan, the fumes can be better discharged, and thus an ideal exhaust effect can be achieved while saving energy. While ensuring the cleanliness of the air in the kitchen, the health level of the cooking person is improved.

[0047] Further, the driving module has a first driving mode and a second driving mode. In the first driving mode, the driving module drives the movable panel 3 to slide and open or close the normally open air suction port 1112. It should be noted that in the first driving mode, the fumes in the kitchen can be discharged only through the normally open air suction port 1112, which can ensure the cleanliness of the kitchen air. Further, in the second driving mode, the driving module simultaneously drives the baffle 2 and the movable panel 3 to slide, so that the baffle 2 opens part or all of the normally closed air suction ports 1111 to adjust the air suction area of the effective air suction port. It should be noted that in the second driving mode, the amount of fumes in the kitchen increases. By adjusting the air suction areas of the normally open air suction port 112 and the normally closed air suction port 111, that is, without increasing the rotation speed of the exhaust fan, the fumes can be better discharged, and thus an ideal exhaust effect can be achieved while saving energy.

[0048] In the prior art, the size of the air suction opening of the range hood is fixed, that is, the air suction area of the air suction opening is fixed; when there is a large amount of flue gas in the kitchen, due to the limitation of the air suction area, even if the rotation speed of the exhaust fan is increased, the ideal exhaust effect cannot be achieved. However, for the range hood according to the embodiment of the present invention, the air suction area of the air suction opening 111 can be adjusted more flexibly according to the amount of flue gas in the kitchen, that is, it is not necessary to increase the rotation speed of the exhaust fan to better discharge the flue gas, so as to achieve the ideal exhaust effect while saving energy; while ensuring the cleanliness of the air in the kitchen, the health level of the cooking personnel is improved.

[0049] For the range hood according to an embodiment of the present invention, as Figure 1 shown, a groove 112 is provided on the air suction panel 11, and the air suction opening 111 is arranged in the groove 112. In this way, the groove 112 can provide an installation space for the air suction opening 111, and can provide an avoidance space for the baffle 2 when blocking the air suction opening 111. At the same time, the groove 112 can also better protect the air suction opening 111, and is convenient for the flue gas to be inhaled from the groove 112 into the air suction opening 111, thereby improving the cleanliness of the air in the kitchen and ensuring the health level of the cooking personnel; further, the baffle 2 is slidably connected to the groove 112. For example, in a specific embodiment, when it is necessary to exhaust the flue gas in the kitchen, the baffle 2 slides open the groove 112, so that the air suction opening 111 sucks away the flue gas in the kitchen, while ensuring the cleanliness of the air in the kitchen, the health level of the cooking personnel is improved. When the range hood stops working, the air suction opening 111 stops working. At this time, the baffle 2 slides to close the groove 112, so as to realize the blocking of the air suction opening 111 by the baffle 2, thereby ensuring the aesthetics of the range hood; further, the width of the baffle 2 is greater than the width of the air suction opening 111, so as to facilitate the blocking of the air suction opening 111 by the baffle 2 and ensure the aesthetics of the range hood; further, the height of the baffle 2 is less than the height of the groove 112, so as to facilitate the part of the air suction opening 111 exposed from the rear side of the movable panel 3 to form an effective air suction opening. In this way, through the effective air suction opening formed by the air suction opening 111 behind the movable panel 3, the flue gas in the kitchen can be absorbed, thereby improving the cleanliness of the air in the kitchen and ensuring the health level of the cooking personnel.

[0050] In the description of the present invention, the "first feature" and "second feature" may include one or more of such features.

[0051] For the range hood according to an embodiment of the present invention, as Figure 5As shown in the figure, the baffle 2 includes a decorative panel 21 located above the air suction port 111 and a movable baffle 22 located below the decorative panel 21. In this way, by setting the decorative panel 21 on the air suction panel 11, it is beneficial to improve the aesthetics of the range hood. The baffle 2 can open or close the air suction port 111 through the movable baffle 22. For example, in a specific embodiment, when it is necessary to exhaust the kitchen fumes, the movable baffle 22 slides open the groove 112, so that the air suction port 111 sucks away the kitchen fumes, while ensuring the cleanliness of the air in the kitchen and improving the health level of the cooking personnel. When the range hood stops working, the air suction port 111 stops working. At this time, the movable baffle 22 slides to close the groove 112, so as to realize the shielding of the air suction port 111 by the movable baffle 22, and further ensure the aesthetics of the range hood. Further, an avoidance opening is provided on the baffle 2. A part of the avoidance opening is located on the decorative panel 21, and the other part is located on the movable baffle 22. The avoidance opening can provide an avoidance space for the opening or closing of the baffle 2, so as to cooperate to realize the working or stopping of the air suction port 111. Further, the upper edge of the decorative panel 21 extends upward to the upper edge of the groove 112. When the driving module adopts the first driving mode, the movable baffle 22 is connected to the decorative panel 21, and the avoidance opening forms a normally open air suction port. For example, in a specific embodiment, when the amount of fumes in the kitchen is small, only the normally open air suction port 112 can work to suck away the fumes, so as to ensure the cleanliness of the air in the kitchen.

[0052] In the description of the present invention, the meaning of "a plurality of" is two or more.

[0053] According to an embodiment of the present invention, the air suction panel assembly is as Figure 4 shown. After the movable panel 3 opens the normally open air suction port 1112, the movable panel 3 and the baffle 2 move synchronously, so that part of the normally closed air suction ports 1111 can be exposed from the rear side of the movable panel 3 to increase the air intake area of the effective air suction ports, so as to absorb the kitchen fumes, and further improve the cleanliness of the air in the kitchen, thereby ensuring the health level of the cooking personnel. For example, in a specific embodiment, when the cooking personnel cook in the kitchen and generate fumes, the movable panel 3 can be controlled to open, so that the air suction port 111 opens, and then the normally open air suction port 1112 enters the working state. When the normally open air suction port 1112 is working normally and the amount of fumes in the kitchen increases, the normally closed air suction ports 1111 can be opened to suck away the excess fumes. Furthermore, the air intake area of the air suction port can be adjusted more flexibly according to the amount of fumes in the kitchen, so as to achieve an ideal smoke exhaust effect while saving energy.

[0054] According to the air suction panel assembly of an embodiment of the present utility model, during the process of opening the normally open air suction port 1112 and increasing the air suction area of the effective air suction port, the movable panel 3 always blocks the baffle 2, so that the air suction area of the air suction port can be adjusted more flexibly according to the amount of flue gas in the kitchen, thereby achieving an ideal smoke exhaust effect while saving energy.

[0055] According to the range hood of an embodiment of the present utility model, the driving module includes a driving member 4, a guiding assembly 5 and an elastic assembly 6. In this way, the driving of the movable panel 3 can be realized through the driving module, so as to realize the opening or closing of the air suction port 111; further, the guiding assembly 5 includes a guiding seat 51, a first sliding strip 52 and a second sliding strip 53. The guiding seat 51 is arranged on the rear side wall surface of the air suction panel 11. The guiding assembly 5 can provide a guiding effect for the driving of the movable panel 3; further, the first sliding strip 52 and the second sliding strip 53 are slidably connected to the guiding seat 51, and the second sliding strip 53 is connected to the driving end of the driving member 4. In this way, the guiding seat 51 provides a guiding effect for the movement of the first sliding strip 52 and the second sliding strip 53, and the second sliding strip 53 is connected to the driving end of the driving member 4, so that the driving module is used to drive the movable panel 3 to move, so as to open or close the air suction port 111, and further make the normally open air suction port 1112 enter the working state or the stop state; further, the baffle 2 is connected to the first sliding strip 52, and the movable panel 3 is connected to the second sliding strip 53. In this way, by connecting the first sliding strip 52 to the baffle 2 and the second sliding strip 53 to the movable panel 3, the driving module can open or close the normally closed air suction port 1111 and the normally open air suction port 1112, that is, when the cooking personnel generate flue gas during cooking in the kitchen, the movable panel 3 can be controlled to open, so that the air suction port 111 is opened, and further the normally open air suction port 1112 enters the working state; when the normally open air suction port 1112 is working properly and the amount of flue gas in the kitchen increases, the normally closed air suction port 1111 can be opened to suck away the excess flue gas; further, such as Figure 7As shown, the elastic component 6 is arranged in the moving direction of the first slide bar 52. The first slide bar 52 can be driven by the elastic component 6, so as to open or close the baffle 2. Further, the second slide bar 53 has a first position, a second position and a third position. Further, when the driving module is in the first driving mode, the driving member 4 drives the second slide bar 53 to slide between the first position and the second position, and the second slide bar 53 does not apply a force to the first slide bar 52, so that the movable panel 3 can be controlled to open, so that the air suction port 111 is opened, and then the normally open air suction port 1112 enters the working state. It should be noted that at this time, the amount of flue gas in the kitchen is not too much, and the working of the normally open air suction port 1112 can meet the demand for smoke exhaust. Further, when the driving module is in the second driving mode downward, the second slide bar 53 slides from the second position to the third position, and the second slide bar 53 drives the first slide bar 52 to slide and compress the elastic component 6, or when the second slide bar 53 slides from the third position to the second position, the elastic component 6 resets and drives the first slide bar 52 to reset. In this way, when the normally open air suction port 112 is working properly and the amount of flue gas in the kitchen increases, the normally closed air suction port 111 can be opened to suck away the excess flue gas, so that it is not necessary to increase the rotation speed of the smoke exhaust fan to better exhaust the flue gas, thereby achieving an ideal smoke exhaust effect while saving energy; while ensuring the cleanliness of the air in the kitchen, improving the health level of the cooking personnel.

[0056] In the description of the present invention, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include indirect contact between the first and second features through additional features therebetween.

[0057] The range hood according to an embodiment of the present invention, such as Figure 7 and Figure 8As shown, a first connecting plate 54 is connected to the first sliding bar 52, and the first connecting plate 54 is connected to the baffle 2. Further, a second connecting plate 55 is connected to the second sliding bar 53, and the second connecting plate 55 is connected to the movable panel 3. In this way, through the connection between the first connecting plate 52 and the baffle 2, the connection between the second connecting plate 53 and the movable panel 3, and the guiding action of the guiding component 5 on the corresponding side, the suction area of the suction port 111 can be adjusted more flexibly according to the amount of cooking fumes in the kitchen. That is, when a cooking person generates fumes during cooking in the kitchen, the movable panel 3 can be controlled to open, so that the suction port 111 opens, and then the normally open suction port 1112 enters the working state; when the normally open suction port 1112 is working normally and the amount of cooking fumes in the kitchen increases, the baffle 2 can be controlled to open, and the normally closed suction port 1111 can be opened to suck away the excess amount of cooking fumes; in this way, it is not necessary to increase the rotation speed of the exhaust fan to better discharge the cooking fumes, so as to achieve an ideal exhaust effect while saving energy; and ensure the cleanliness of the air in the kitchen. Further, the elastic component 6 acts on the first connecting plate 54, so that through the elastic component 6, when the range hood stops working, the baffle 2 and the movable panel 3 can be closed.

[0058] For a range hood according to an embodiment of the present utility model, the guiding seat 51 has a first guiding portion and a second guiding portion. The first sliding strip 52 is slidably connected to the first guiding portion, and the second sliding strip 53 is slidably connected to the second guiding portion. The first guiding portion and the second guiding portion can provide guiding effects for the movement of the driving module, so that the driving module is used to drive the movable panel 3, thereby opening or closing the air suction opening 111, and further enabling the normally open air suction opening 1112 to enter the working state or the stop state. Further, the range hood further includes a starting portion 551. Specifically, the starting portion 551 slides with the second sliding strip 53. When the second sliding strip 53 is in the second position, the starting portion 551 acts on the first sliding strip 52, thereby realizing the driving of the movable panel 3, and enabling the normally open air suction opening 1112 to enter the working state. Further, when the second sliding strip 53 moves from the second position to the third position, the starting portion 551 drives the first sliding strip 52 to slide along the first guiding portion and compress the elastic component 6, thereby realizing the driving of the baffle 2, and enabling the normally closed air suction opening 1111 to enter the working state. In this way, by connecting the first sliding strip 52 with the baffle 2 and connecting the second sliding strip 53 with the movable panel 3, the driving module can open or close the normally closed air suction opening 1111 and the normally open air suction opening 1112. That is, when a cooking person generates fumes in the kitchen, the movable panel 3 can be controlled to open, so that the air suction opening 111 is opened, and further the normally open air suction opening 1112 enters the working state. When the normally open air suction opening 1112 is working properly and the amount of fumes in the kitchen increases, the normally closed air suction opening 1111 can be opened to suck away the excess amount of fumes. In this way, it is not necessary to increase the rotation speed of the exhaust fan to better discharge the fumes, thereby achieving an ideal exhaust effect while saving energy, and improving the health level of the cooking person while ensuring the cleanliness of the air in the kitchen.

[0059] In the description of the present utility model, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature.

[0060] For a range hood according to an embodiment of the present utility model, as Figure 7 and Figure 8 shown, it further includes a supporting portion 552. Further, the supporting portion 552 slides with the second sliding strip 53. Further, when the second sliding strip 53 is in the first position, the supporting portion 552 supports the first sliding strip 52 from below the first sliding strip 52. Further, when the movable panel 3 closes the normally open air suction opening 1112, the supporting portion 552 supports on the lower edge of the first sliding strip 52 and applies an upward acting force to the first sliding strip 52.
