[0020] Example 1

[0021] Combined with Figure 1-4The present embodiment proposes a flap mechanism, including a flap 20 and a rotating bracket 21, a fixing member 22, a fixing bracket 10, a first connecting rod 11, a second connecting rod 12, a third connecting rod 13 and a driving part located in the integrated stove head 200, wherein the fixing member 22 and the fixing bracket 10 are fixedly connected to the integrated stove head 200, one end of the rotating bracket 21 is hinged to the fixing member 22, the other end of the rotating bracket 21 is fixedly connected to the flap 20, and the third connecting rod 13 is movably connected to the rotating bracket 21; the second connecting rod 12 and the third connecting rod 13 are longitudinally connected. The driving part is configured to drive the second connecting rod 12 to move in the longitudinal direction, wherein the longitudinal direction is the direction in which the integrated stove head 200 points to the ground; a first hinge portion 101 is provided in the middle of the first connecting rod 11 near the third connecting rod 13, and the first connecting rod 11 is hinged to the fixed bracket 10 through the first hinge portion 101; a second hinge portion 102 and a third hinge portion 103 are respectively provided at both ends of the first connecting rod 11, and the first connecting rod 11 is hinged to the second connecting rod 12 through the second hinge portion 102, and is hinged to the third connecting rod 13 through the third hinge portion 103.

[0022] Combined with Figure 3 and 4 A flap mechanism of this embodiment is used on an integrated stove, wherein the first connecting rod 11 serves as a lever, which can amplify the force of the driving part and output to drive the flap 20 to flip, thereby realizing efficient motion transmission. At the same time, the second connecting rod 12 and the third connecting rod 13 are arranged longitudinally, making full use of the longitudinal space, and the overall structure is simple, which greatly saves the internal space of the machine head.

[0023] In this embodiment, the fixing member 22 is fixed to the integrated stove head 200 and is hinged to the end of the rotating bracket 21 to serve as the rotation fulcrum of the rotating bracket 21, that is, as the rotation center of the flap 20. The fixing bracket 10 is fixedly arranged in the head 200 and is used to carry the first connecting rod 11 and other structures. The driving part is used to provide power and exert a force on the first connecting rod 11 by driving the longitudinal movement of the second connecting rod 12.

[0024] In this embodiment, a first hinged portion 101 is provided at the middle of the first link 11 near the third link 13, and the first link 11 is hinged to the fixed bracket 10 through the first hinged portion 101, so the first link 11 constitutes a labor-saving lever. The driving unit transmits the force to the first link 11 through the connection between the second link 12 and the first link 11, and the force is concentrated on the second hinged portion 102, so that the part from the first hinged portion 101 to the second hinged portion 102 on the first link 11 constitutes the power arm of the labor-saving lever; at the same time, the rotating bracket 21 is hinged to the first link 11 through the third link 13, so that the part from the first hinged portion 101 to the third hinged portion 103 on the first link 11 constitutes the resistance arm of the labor-saving lever. Obviously, since the first hinged portion 101 is provided at the middle portion of the first connecting rod 11 close to the third connecting rod 13, the length of the power arm is greater than the length of the resistance arm, and the first connecting rod 11 constitutes a force-saving lever, so the force transmitted from the driving portion to the second connecting rod 12 can be amplified and output, thereby realizing efficient transmission of power.

[0025] The first hinge part 101, the second hinge part 102 and the third hinge part 103 are all structures located on the first connecting rod 11 for realizing hinged or rotational connection, such as structural holes, latches, raised or recessed columnar structures, or other connection structures that can realize hinged connection.

[0026] Furthermore, in this embodiment, in addition to the first connecting rod 11 rotating in the vertical plane in which it is located, the second connecting rod 12 and the third connecting rod 13 are both arranged longitudinally, and the movement direction of the two is also longitudinally, thereby achieving full utilization of the longitudinal space inside the machine head 200, so that the space inside the machine head 200 of the integrated stove in the width direction is less, thereby saving the space occupied by the machine head 200 as a whole.

[0027] It is worth noting that when the head 200 of the integrated stove is extracting smoke, the lateral space of the head 200 is more important than its longitudinal space for the extracting smoke effect, and the full utilization of the longitudinal space in this embodiment can save the lateral space. Therefore, in actual use, the extracting smoke effect of this embodiment can also be guaranteed.

[0028] Obviously, for a labor-saving lever, the larger the ratio of the power arm to the resistance arm, the better. The distance from the first hinge 101 to the second hinge 102 is defined as L1, that is, the length of the power arm is L1, and the distance from the first hinge 101 to the third hinge 103 is defined as L2, that is, the length of the resistance arm is L2. When L1:L2≥1.1 is satisfied, a better power transmission effect can be achieved. However, in the handpiece 200, due to limited space, it is necessary to comprehensively consider space occupancy and transmission efficiency. Therefore, in a more preferred embodiment, L1:L2 can be taken as 1.2.

[0029] The driving part is used to drive the second connecting rod 12 to move in the height direction, but the arrangement of the driving part is not unique. Figure 3 In one embodiment, the driving part includes an electric push rod 310, which is arranged longitudinally and located on one side of the fixed bracket 10, and one end of the second connecting rod 12 is provided with a first connecting portion 311 and a first extending portion 312, and the first connecting portion 311 is connected to the second connecting rod 12 through the first extending portion 312, and the first connecting portion 311 is hinged to the output end of the electric push rod 310. In this embodiment, the electric push rod 310 is used to provide power. The first connecting portion 311 and the first extending portion 312 can realize the connection between the second connecting rod 12 and the output end of the electric push rod 310 when there is a misalignment between the output end of the electric push rod 310 and the second connecting rod 12. And because the electric push rod 310 is arranged longitudinally, the output direction of the electric push rod 310 can be upward or downward relative to the ground. This arrangement also achieves the reasonable use of the longitudinal space in the head 200.

[0030] In a further embodiment, the output end of the electric push rod 310 is located at the lower part of the main body of the electric push rod 310, the second connecting rod 12 extends longitudinally downward from the second hinge portion 102 to the integrated stove head 200, and the hinge position between the output end of the electric push rod 310 and the first connecting portion 311 is located at the lower side of the second connecting rod 12. Since the flap 20 is close to the top of the head 200, there is actually not much space on the upper part of the head 200. This embodiment can make full use of the relatively lower longitudinal space to meet the telescopic activity of the output end of the electric push rod 310, further making full use of the longitudinal space of the head 200.

[0031] Combined with Figure 4 In another embodiment, the driving unit includes a motor 320 and a fourth connecting rod 321, the motor 320 is fixed to the fixed bracket 10, the output end of the motor 320 is fixedly connected to one end of the fourth connecting rod 321, and the other end of the fourth connecting rod 321 is hinged to the second connecting rod 12. In this embodiment, the smaller motor 320 is used as a power source, and the rotation of the output shaft of the motor 320 is transmitted to the second connecting rod 12 through the fourth connecting rod 321, so that the second connecting rod 12 can move longitudinally. Since the volume of the motor 320 that meets the use is smaller than that of the electric push rod 310, this embodiment can further save space in the head 200.

[0032] In a further embodiment, the output end of the motor 320 is located at the lower side of the first connecting rod 11, and the hinge position of the fourth connecting rod 321 and the second connecting rod 12 is located at the lower side of the second connecting rod 12. Similar to the effect that can be achieved by extending the output end of the electric push rod 310 downward, when the output end of the motor 320 is set at the lower side of the first connecting rod 11, the fourth connecting rod 321 is also located at the lower side of the first connecting rod 11, thereby further making full use of the relatively lower longitudinal space.

[0033] Combined with Figure 3 and 4 , the third connecting rod 13 is movably connected to the rotating bracket 21, and is used to transmit the driving force to the rotating bracket 21. However, due to the complex structure of the machine head 200, there may be misalignment between the rotating bracket 21 and the third connecting rod 13. Therefore, in one embodiment, the flap mechanism further includes a second connecting portion 131 and a second extending portion 132, and the second connecting portion 131 and the third connecting rod 13 are connected via the second extending portion 132, and the second connecting portion 131 is movably connected to the rotating bracket 21. Therefore, the second connecting portion 131 and the second extending portion 132 can ensure the connection between the rotating bracket 21 and the third connecting rod 13 when there is misalignment between the two.

[0034] Example 2

[0035] Combined with Figure 1-4 , this embodiment proposes a machine head, including a flap mechanism of embodiment 1.

[0036] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
