Referring to fig. 1 and 2, the present application firstly provides a panel turnover structure, which includes a housing 10, a panel turnover 20, a driving member 30, a linkage assembly 40 and a cleaning assembly 50, wherein the panel turnover 20 is rotatably connected to the housing 10, two ends of the driving member 30 are respectively rotatably connected to the housing 10 and the panel turnover 20, and the driving member 30 can stretch along its length direction to drive the panel turnover 20 to rotate; the linkage assembly 40 and the cleaning assembly 50 are both arranged on the turning plate 20, the linkage assembly 40 is in power connection with the cleaning assembly 50, one end of the driving piece 30 is in rotary connection with the turning plate 20 through the linkage assembly 40, and the driving piece 30 can drive the cleaning assembly 50 to slide relative to the turning plate 20 through the linkage assembly 40 and clean the turning plate 20.

After the turning plate 20 is turned over and opened, the upward rising of the oil smoke can be prevented, so that the oil smoke is conveniently sucked by the range hood, and a driving piece 30 is required to be arranged for driving the turning plate 20 in order to realize the turning function of the turning plate 20;

in this application, through set up linkage subassembly 40 on turning over board 20 to with driving piece 30 and linkage subassembly 40 are connected, so that driving piece 30 when the drive turns over board 20 rotation, still can be through the work of linkage subassembly 40 drive clean subassembly 50, accomplish the cleanness of attaching the greasy dirt on turning over board 20 through clean subassembly 50 for turning over the slip of board 20, need not additionally to add the power supply and can add self-cleaning function for turning over the board structure, effectively avoided because of addding the clean function of board 20 and lead to the condition emergence that lampblack absorber inner space is tension, the cost increases by a wide margin.

Referring to fig. 1 and 2, in some embodiments, the linkage assembly 40 includes a guide post 41, a slider 42 and a connecting rod 43, the guide post 41 is fixedly disposed on the flap 20, the slider 42 is slidably connected to the guide post 41 along the length direction of the guide post 41, one end of the driving member 30 and one end of the connecting rod 43 are rotatably connected to the slider 42, and the other end of the connecting rod 43 is connected to the cleaning assembly 50.

During the extension of the driving member 30, the pushing force applied by the driving member 30 to the slider 42 can be decomposed into two mutually perpendicular force components, namely, a force component along the length direction of the guide post 41 and a force component perpendicular to the length direction of the guide post 41.

Wherein, the component force along the length direction of the guide post 41 can drive the sliding block 42 to slide along the length direction of the guide post 41, and the cleaning component 50 is driven to work through the connecting rod 43 rotationally connected with the sliding block 42; along the component force perpendicular to the length direction of the guide post 41, the sliding block 42 abuts against the guide post 41, and the guide post 41 is fixedly arranged on the turning plate 20, so that the turning plate 20 can be driven to rotate by the sliding block 42 and the guide post 41; thereby realizing the two actions of simultaneously completing the rotation of the turning plate 20 and the working of the cleaning assembly 50 through the driving piece 30.

Referring to fig. 1 and 2, in some embodiments, the linkage assembly 40 further includes a spring 44, the guide post 41 is provided with a guide cavity 41a, the slider 42 is slidably connected with the inner wall of the guide cavity 41a, one end of the spring 44 abuts against the slider 42, and the other end abuts against the inner wall of the guide cavity 41 a; the spring 44 deforms the stored force during extension of the driver 30 and releases the recovery during retraction of the driver 30.

If in some cases, the turning plate 20 rotates until the component force of the driving piece 30 perpendicular to the length direction of the guide post 41 just faces or is far away from the rotation center of the turning plate 20, then the component force perpendicular to the length direction of the guide post 41 cannot drive the turning plate 20 to rotate further, that is, the turning plate 20 rotates to have a dead point; by adding the spring 44, a part of the component force of the driving member 30 along the length direction of the guide post 41 can act on the guide post 41 through the spring 44 to drive the turning plate 20 to rotate, and the two component force directions of the driving member 30 are mutually perpendicular, so that the dead point of the turning plate 20 can be eliminated.

In addition, when the driving member 30 drives the slider 42 to slide, a friction force exists between the slider 42 and the inner wall of the guiding cavity 41a, and the slider 42 also needs to drive the cleaning assembly 50 to work through the connecting rod 43; it will be appreciated that in some cases, if the component force along the length direction of the guide post 41 is smaller than the resultant force of the friction force of the slider 42 and the resistance force of the link 43 when the driving member 30 is contracted, the slider 42 cannot be reset to the initial position under the driving of the driving member 30; by providing the spring 44 in the guide chamber 41a, elastic potential energy can be accumulated by deformation of the spring 44 when the driver 30 is extended, and the elastic potential energy can be released when the driver 30 is contracted, thereby assisting the slider 42 to return in the longitudinal direction of the guide post 41, and ensuring that the slider 42 can return to the initial position.

As shown in fig. 1 and 2, in some embodiments, the spring 44 is a compression spring, and the spring 44 is located between the slider 42 and the inner wall of the guiding cavity 41a near the flap 20.

In the process of extending the driving piece 30, one end of the spring 44 abuts against the sliding block 42, the component force of the driving piece 30 along the length direction of the guide post 41 presses the spring 44 through the sliding block 42, at this time, the other end of the spring 44 abuts against the inner wall of the guide cavity 41a, and the guide post 41 is fixedly arranged on the turning plate 20, so that the component force of the driving piece 30 along the length direction of the guide post 41 can also push the guide post 41 and the turning plate 20 to rotate through the spring 44.

The force component of the driving member 30 along the length direction of the guide post 41 is used for pressing the spring 44, and the other part is used for pushing the turning plate 20 to rotate, wherein the pressing amount of the spring 44 depends on the magnitude of the reaction force of the inner wall of the guide cavity 41a to the spring 44, the larger the limit value of the reaction force is, the larger the pressing amount of the spring 44 is (the reaction force is smaller than the force component of the driving member 30 along the length direction of the guide post 41 on the premise of being smaller), and the reaction force is derived from the resistance force applied by the turning plate 20 in the rotating process, so that the pressing amount of the spring 44 can be increased by increasing the rotating friction force of the turning plate 20, and the same applies to the other part.

Referring to fig. 1 and 2, in some embodiments, the driving member 30 has three states of less than 180 °, equal to 180 ° and greater than 180 ° with respect to the guide post 41 during the extension and retraction of the driving member 30.

When the extending and contracting direction of the driving member 30 is parallel to the length direction of the guide post 41, the sliding block 42 only receives force along the length direction of the guide post 41, and in the extending and contracting process of the driving member 30 by designing the turning plate structure, an included angle between the driving member 30 and the guide post 41 is smaller than 180 degrees, equal to 180 degrees and larger than 180 degrees, so that the component force along the length direction of the guide post 41 received by the sliding block 42 can be increased first, and then reduced after being increased to the limit, thereby ensuring that the component force along the length direction of the guide post 41 received by the sliding block 42 is relatively large all the time, and the spring 44 can be fully deformed to accumulate elastic potential energy.

Referring to fig. 1 and fig. 2, in some embodiments, the guide post 41 is perpendicular to the flap 20, so that a right triangle is formed among the flap 20, the guide post 41 and the link 43, when the driving member 30 drives the slider 42 to slide along the length direction of the guide post 41, i.e. one right triangle side is shortened, and because the length of the link 43 is fixed, the length of the other right triangle side of the right triangle side is changed along with the sliding of the slider 42, i.e. the connecting end of the link 43 and the flap 20 moves to a side far from or near to the guide post 41, so that the link 43 can drive the cleaning assembly 50 to clean the flap 20.

Referring to fig. 3, in some embodiments, the cleaning assembly 50 includes a cleaning brush 51, a sliding seat 52 and a guide rail 53, the guide rail 53 is fixedly arranged on the turning plate 20, the sliding seat 52 is slidably connected with the guide rail 53, the cleaning brush 51 is fixedly arranged on the sliding seat 52, and the other end of the connecting rod 43 is rotatably connected with the cleaning brush 51.

Because the sliding seat 52 is slidably connected with the guide rail 53, the sliding seat 52 can only move along the length direction of the guide rail 53, so that when the connecting rod 43 swings under the driving of the sliding block 42, the sliding seat 52 and the cleaning brush 51 can be driven to slide along the length direction of the guide rail 53, and cleaning of the turning plate 20 is completed.

In some embodiments, the cleaning assembly 50 includes a plurality of guide rails 53 disposed parallel to each other, each guide rail 53 is slidably connected to a sliding seat 52, and the cleaning brush 51 is fixedly connected to each sliding seat 52; the cleaning brush 51 is supported by the sliding seats 52, so that the sliding stability of the cleaning brush 51 can be increased, and the cleaning brush 51 is ensured to be closely attached to the surface of the turning plate 20, so that the cleaning quality is improved.

Referring to fig. 3, in some embodiments, the cleaning assembly 50 includes a synchronizing rod 54, a plurality of sliding seats 52, and a plurality of cleaning brushes 51 corresponding to the sliding seats 52 one by one, wherein each sliding seat 52 is slidably connected with the guide rail 53 and is fixed to the synchronizing rod 54, and each cleaning brush 51 is fixed to the corresponding sliding seat 52; so that the connecting rod 43 can drive the plurality of cleaning brushes 51 to clean the flap 20 through the synchronizing rod 54 at the same time, thereby increasing the cleaning range of the cleaning assembly 50 and improving the cleaning efficiency.

Referring to fig. 4, a second aspect of the present application provides a range hood, including a flap structure as described above.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
