It 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 on the present utility model.

[0039] Reference is made below to Figures 1-6 describe the linkage drive mechanism according to an embodiment of the present utility model. As Figure 1 shown, the linkage drive mechanism according to an embodiment of the present utility model includes:

[0040] a driving member 1;

[0041] a guiding assembly 2. Further, the guiding assembly 2 includes a guiding seat 21, a first sliding bar 22 and a second sliding bar 23. Further, the first sliding bar 22 and the second sliding bar 23 are slidably connected to the guiding seat 21, so that the guiding seat 21 provides a guiding effect on the movement of the first sliding bar 22 and the second sliding bar 23. Further, the second sliding bar 23 is connected to the driving end of the driving member 1. In this way, the guiding assembly 2 is connected to the driving end of the driving member 1 through the second sliding bar 23, and thus can provide a guiding effect on the movement of the driving member 1;

[0042] an elastic assembly 3. Further, the elastic assembly 3 is disposed in the moving direction of the first sliding bar 22; the elastic assembly 3 can provide an elastic force for the movement of the first sliding bar 22. For example, in a specific embodiment, when the first sliding bar 22 moves downward, the elastic assembly 3 is compressed and accumulates elastic force; when the first sliding bar 22 moves upward, the elastic assembly 3 releases the elastic force and restores its original state;

[0043] Further, the second sliding bar 23 has a first position, a second position and a third position. When the second sliding bar 23 slides between the first position and the second position, the second sliding bar 23 does not apply a force to the first sliding bar 22, so that the second sliding bar 23 and the first sliding bar 22 do not interfere with each other during the driving process. Further, when the second sliding bar 23 slides from the second position to the third position, the second sliding bar 23 drives the first sliding bar 22 to slide and compresses the elastic assembly 3. Further, when the second sliding bar 23 slides from the third position to the second position, the elastic assembly 3 is reset and drives the first sliding bar 22 to reset; in this way, the air suction area can be adjusted more flexibly according to the amount of fumes in the kitchen, achieving an ideal smoke exhaust effect while improving the overall aesthetics of the range hood.

[0044] In the prior art, the air suction openings of range hoods are mostly open, making the range hoods look less aesthetically pleasing. Moreover, the size of the air suction openings is fixed, that is, the air suction area of the air suction openings is fixed, and it is impossible to adjust the size of the air suction area according to the amount of fumes in the kitchen. According to the linkage driving mechanism of the embodiments of the present invention, the air suction area can be adjusted more flexibly according to the amount of fumes in the kitchen, achieving an ideal smoke exhaust effect while improving the overall aesthetics of the range hood.

[0045] According to a linkage driving mechanism of an embodiment of the present invention, as Figure 5 shown, the guiding seat 21 has a first guiding portion and a second guiding portion. The first sliding strip 22 is slidably connected to the first guiding portion, and the second sliding strip 23 is slidably connected to the second guiding portion. In this way, the first guiding portion can provide a guiding effect for the sliding of the first sliding strip 22, and the second guiding portion can provide a guiding effect for the sliding of the second sliding strip 23. Furthermore, the air suction area can be adjusted more flexibly according to the amount of fumes in the kitchen, achieving an ideal smoke exhaust effect while improving the overall aesthetics of the range hood. Further, the linkage driving mechanism further includes a starting portion 251. Specifically, the starting portion 251 slides with the second sliding strip 23. When the second sliding strip 23 is in the second position, the starting portion 251 acts on the first sliding strip 22. In this way, by the starting portion 251 acting on the first sliding strip 22, the starting of the first sliding strip 22 can be promoted. Further, when the second sliding strip 23 moves from the second position to the third position, the starting portion 251 drives the first sliding strip 22 to slide along the first guiding portion and compress the elastic component 3. In this way, through the action of the first sliding strip 22 and the second sliding strip 23, the air suction area can be adjusted more flexibly according to the amount of fumes in the kitchen, achieving an ideal smoke exhaust effect while improving the overall aesthetics of the range hood.

[0046] In the description of the present invention, the "first feature" and the "second feature" may include one or more of such features.

[0047] According to a linkage driving mechanism of an embodiment of the present invention, as Figure 6 shown, it further includes a supporting portion 252. Further, the supporting portion 252 slides with the second sliding strip 23. Further, when the second sliding strip 23 is in the first position, the supporting portion 252 supports the first sliding strip 22 from below the first sliding strip 22. In this way, the supporting portion 252 can provide a supporting effect for the up and down movement of the second sliding strip 23, ensuring the stability of the up and down movement of the second sliding strip 23.

[0048] According to a linkage driving mechanism of an embodiment of the present invention, the first guiding portion and the second guiding portion are provided on two mutually perpendicular surfaces of the guiding seat 21; the first guiding portion and the second guiding portion can provide a guiding effect for the movement of the first sliding strip 22 and the second sliding strip 23.

[0049] In the description of the present utility model, "a plurality of" means two or more than two.

[0050] The linkage driving mechanism according to an embodiment of the present utility model, as Figure 4 shown, further includes a synchronization component 6. Further, the number of the guiding components 2 and the elastic components 3 is two. It should be noted that the number of the guiding components 2 and the elastic components 3 can also be other numbers, which will not be elaborated here; further, the driving member 1 drives the synchronization component 6 so that the synchronization component 6 synchronously drives the two guiding components 2, so that the synchronization component 6 can provide a guiding function for the movement of the two guiding components 2; further, the first sliding strips 22 of the two groups of guiding components 2 are all connected to the baffle 52, and the second sliding strips 23 are all connected to the movable panel 53; thus, the guiding components 2 can provide a guiding function for the driving of the movable panel 53, so as to better realize the opening or closing of the movable panel 53.

[0051] In the description of the present utility model, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween.

[0052] The linkage driving mechanism according to an embodiment of the present utility model, as Figure 4 shown, the synchronization component 6 includes a synchronization shaft 61, a first connecting rod 62, a second connecting rod 63 and a third connecting rod 64. Further, both ends of the first connecting rod 62 are connected with the second connecting rod 63, and the second connecting rod 63 is rotatably connected with the third connecting rod 64, and the third connecting rod 64 is connected with the second sliding strip 23 on the corresponding side. Further, the driving end of the driving member 1 is connected to the first end of the first connecting rod 62, and the second end of the first connecting rod 62 is connected to the end where the second connecting rod 63 is connected to the third connecting rod 64; thus, through the cooperation of the synchronization shaft 61, the first connecting rod 62, the second connecting rod 63 and the third connecting rod 64, the synchronization of the driving of the movable panel 53 can be realized, and thus an ideal smoke exhaust effect can be achieved.

[0053] In summary, the linkage driving mechanism according to the embodiment of the present utility model can more flexibly adjust the air suction area according to the amount of smoke in the kitchen, achieve an ideal smoke exhaust effect while improving the overall aesthetics of the range hood.

[0054] The range hood according to the second aspect of the present utility model is provided with the linkage driving mechanism as described in any one of the first aspect, as Figure 3As shown, it includes a range hood main body 4. The range hood main body 4 has an air suction panel assembly 5. The air suction panel assembly 5 is arranged on the air suction side of the range hood main body 4. Through the air suction panel assembly 5, the air suction area of the air suction port can be adjusted more flexibly according to the amount of flue gas in the kitchen, so as to achieve an ideal smoke exhaust effect while saving energy; while ensuring the cleanliness of the air in the kitchen, it improves the health level of the cooking personnel; further, the air suction panel assembly 5 includes an air suction plate 51, a baffle 52 and a movable panel 53. Further, an air suction port 511 is provided on the air suction plate 51. The guiding assembly 2 is arranged on the rear side wall surface of the air suction plate 51. The baffle 52 is connected to the first slide bar 22 and is located on the front side of the air suction plate 51. Further, the movable panel 53 is connected to the second slide bar 23 and is located on the front side of the air suction plate 51 and blocks the baffle 52. The baffle 2 is slidably connected to the front side of the air suction plate 51 and blocks the air suction port 511; for example, in a specific embodiment, when the amount of flue gas in the kitchen increases, the amount of flue gas sucked away by opening the air suction port 511 can be increased. Furthermore, the air suction area of the air suction port can be adjusted more flexibly according to the amount of flue gas in the kitchen, so as to achieve an ideal smoke exhaust effect while saving energy; while ensuring the cleanliness of the air in the kitchen, it improves the health level of the cooking personnel.

[0055] Further, when the second slide bar 23 is in the first position, the movable panel 53 shields the baffle 52 and the air suction port 511, thus ensuring the aesthetics of the range hood. Further, when the second slide bar 23 is in the second position, the movable panel 53 opens part of the air suction port 511 and shields the baffle 52. Further, when the second slide bar 23 moves between the second position and the third position, the baffle 52 and the movable panel 53 move synchronously and change the area of the air suction port 511 exposed from the rear side of the movable panel 53. For example, in a specific embodiment, when the cooking personnel generate flue gas during cooking in the kitchen, the movable panel 53 can be controlled to open, so that the air suction port 511 opens, and then the air suction port 511 enters the working state. The baffle 52 can flexibly adjust the area of the air suction port 511 according to the amount of flue gas. When cooking is over, the air suction port 511 stops working. At this time, the movable panel 53 shields the air suction port 511 and the baffle 52, thus ensuring the aesthetics of the range hood; further, the part of the air suction port 511 exposed from the rear side of the movable panel 53 forms an effective air suction port. In this way, through the effective air suction port formed by the air suction port 511 behind the movable panel 53, 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.

[0056] The range hood according to the second aspect of the present utility model may further include a driving module, the driving end of which is connected to the baffle 52 and the movable panel 53; for example, in a specific embodiment, the air suction area of the effective air suction opening may be equal to the air suction area of the air suction opening 511 when the movable panel 53 is opened; in another specific embodiment, the effective air suction opening may be the air suction area of the air suction opening 511 when the baffle 52 is opened. In this way, by adjusting the opening or closing of the baffle 52 and the movable panel 53, the air suction area of the air suction opening 511 can be adjusted, that is, it is not necessary to increase the rotation speed of the exhaust fan to better discharge the flue gas, 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 personnel can be improved.

[0057] 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 air suction opening 511, and then adjusts. It should be noted that in the first driving mode, the amount of flue gas in the kitchen may be the air suction area of the air suction opening 511 when the movable panel 3 is opened, so as to ensure the cleanliness of the kitchen air; further, in the second driving mode, the driving module simultaneously drives the baffle 52 and the movable panel 53 to slide, so that the air suction area of the air suction opening 511 when the baffle 2 is opened is used to adjust the air suction area of the effective air suction opening; it should be noted that in the second driving mode, the amount of flue gas in the kitchen increases, and the air suction area when the baffle 52 and the movable panel 53 are simultaneously driven is used, that is, it is not necessary to increase the rotation speed of the exhaust fan to better discharge the flue gas, and thus an ideal exhaust effect can be achieved while saving energy.

[0058] Further, as Figure 1As shown, the air suction plate 51 is provided with a groove 512, and the air suction port 511 is arranged in the groove 512. In this way, the groove 512 can provide an installation space for the air suction port 511, and can provide an avoidance space for the baffle 52 when the baffle 52 blocks the air suction port 511. At the same time, the groove 512 can better protect the air suction port 511, and is convenient for the flue gas to be inhaled from the groove 512 into the air suction port 511, thereby improving the cleanliness of the air in the kitchen and ensuring the health level of the cooking personnel. Further, the baffle 52 is slidably connected to the groove 512. For example, in a specific embodiment, when it is necessary to exhaust the flue gas in the kitchen, the baffle 52 slides open the groove 512, so that the air suction port 511 sucks away the flue gas in the kitchen, 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 511 stops working. At this time, the baffle 52 slides to close the groove 512, so as to realize the baffle 52 blocking the air suction port 511, and further ensure the aesthetics of the range hood. Further, the width of the baffle 52 is greater than the width of the air suction port 511, so as to facilitate the baffle 52 to block the air suction port 511 and ensure the aesthetics of the range hood. Further, the height of the baffle 52 is less than the height of the groove 512, so as to facilitate the part of the air suction port 511 exposed from the rear side of the movable panel 53 to form an effective air suction port. In this way, through the effective air suction port formed by the air suction port 511 behind the movable panel 53, 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.

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

[0060] Further, as Figure 2As shown, the baffle 52 includes a decorative panel 521 above the air suction port 511 and a movable baffle 522 below the decorative panel 521. In this way, by arranging the decorative panel 521 on the air suction panel 11, it is beneficial to improve the aesthetics of the range hood. The baffle 52 can open or close the air suction port 511 through the movable baffle 522. For example, in a specific embodiment, when it is necessary to exhaust the fumes in the kitchen, the movable baffle 52 slides open the groove 512, so that the air suction port 511 sucks away the fumes in the kitchen, while ensuring the cleanliness of the air in the kitchen and improving the health level of the cooking staff. When the range hood stops working, the air suction port 511 stops working. At this time, the movable baffle 52 slides to close the groove 512, so as to realize the shielding of the air suction port 511 by the movable baffle 52, and further ensure the aesthetics of the range hood. Further, an avoidance opening is provided on the baffle 52. Part of the avoidance opening is located on the decorative panel 521, and the other part is located on the movable baffle 522. The avoidance opening can provide an avoidance space for the opening or closing of the baffle 52, so as to cooperate to realize the working or stopping of the air suction port 511. Further, the upper edge of the decorative panel 521 extends upward to the upper edge of the groove 512. When the second slide bar 23 is between the first position and the second position, the movable baffle 522 is connected to the decorative panel 521, 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 air suction area of the air suction port 511 when the movable panel 3 is opened can be used to work to suck away the fumes, so as to ensure the cleanliness of the air in the kitchen.

[0061] According to the range hood of the second aspect of the present invention, after the movable panel 53 opens the air suction port 511, the movable panel 53 and the baffle 52 move synchronously, so that part of the normally closed air suction port 511 can be exposed from the rear side of the movable panel 53 to increase the air inlet area of the effective air suction port, so that 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 staff. For example, in a specific embodiment, when the cooking staff generates fumes during cooking in the kitchen, the movable panel 53 can be controlled to open, so that the air suction port 511 is opened, and then the air suction port 511 enters the working state. When the amount of fumes in the kitchen increases, the baffle 52 can be opened to increase the air suction port 511 and then suck away the excess amount of fumes. Furthermore, the air suction 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.

[0062] Further, as Figure 6As shown, a first connecting plate 24 is connected to the first sliding bar 22. The first connecting plate 24 is connected to the baffle 52. Further, a second connecting plate 25 is connected to the second sliding bar 23. The second connecting plate 25 is connected to the movable panel 53. In this way, through the connection between the first connecting plate 52 and the baffle 2, and the connection between the second connecting plate 25 and the movable panel 53, and under the guiding action of the guiding component 2 on the corresponding side, the air suction area of the air suction port 511 can be adjusted more flexibly according to the amount of fumes in the kitchen. That is, when a cooking person generates fumes during cooking in the kitchen, the movable panel 53 can be controlled to open, so that the air suction port 511 opens and enters the working state; when the amount of fumes in the kitchen increases, the baffle 52 can be controlled to open to suck away the excess amount of fumes; in this way, it is not necessary to increase the speed of the exhaust fan to better exhaust the fumes, so as to achieve an ideal exhaust effect while saving energy and ensuring the cleanliness of the air in the kitchen. Further, the elastic component 3 acts on the first connecting plate 24. In this way, through the elastic component 3, when the range hood stops working, the baffle 52 and the movable panel 53 can be closed.

[0063] In summary, for the range hood according to the second aspect of the present invention, a linkage driving mechanism as described in any one of the first aspects is provided, so that the air suction area can be adjusted more flexibly according to the amount of fumes in the kitchen, achieving an ideal exhaust effect while improving the overall aesthetics of the range hood.
