If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figure 1A flameout mechanism includes: a base 820, a cover body 810, an air intake pipe 100, a control valve 500 and a flip member 200, wherein the base 820 is provided with a burner 825, and the cover body 810 is rotatably connected to the base 820 and can be rotated to cover or open the burner 825; the air intake pipe 100 is provided on the base 820 and connected to the burner 825, and the air intake pipe 100 is used to supply air to the burner 825; the control valve 500 is connected to the air intake pipe 100 and can control whether the air intake pipe 100 is ventilated or not, and the control valve 500 has a valve stem 510 for controlling its own opening and closing; the flip member 200 is connected to the cover body 810 and can rotate together with the cover body 810; when the flip member 200 rotates, it can drive the valve stem 510 to move relative to the control valve 500. After the control valve 500 is opened and the air intake pipe 100 delivers the gas to the burner 825, the burner 825 can ignite a flame so as to facilitate cooking operations through the flame. When it is necessary to extinguish the flame, the cover 810 can be directly rotated to cover and shield the burner 825. At this time, the cover 810 will drive the flip member 200 to rotate together, and the flip member 200 drives the valve stem 510 of the control valve 500 to move, so that the control valve 500 can close the ventilation state of the air intake pipe 100 through the valve stem 510, so that the effect of extinguishing the flame can be effectively achieved. The flame extinguishing effect can be achieved by directly rotating the cover 810, so it has the advantage of simple operation. In addition, since the cover 810 will make the burner 825 in a shielded state after rotation, the burner 825 can also be protected to prevent foreign impurities from entering the burner 825 and interfering with it. In addition. By judging whether the burner 825 is shielded or not, it is possible to judge whether the flame is extinguished or not. Therefore, the convenience for the user to observe whether the flame is extinguished or not can be increased as much as possible, thereby reducing the problem of forgetting to extinguish the flame or not.

[0032] In certain embodiments, reference Figure 3 The base 820 is provided with a mounting frame 400, and the flip member 200 is hinged to the mounting frame 400; the flip member 200 is provided with a cam portion 250, and the cam portion 250 is protruding relative to the flip member 200, and the cam portion 250 can push the valve stem 510 when rotating. When the cover body 810 drives the flip member 200 to rotate, it will drive the cam portion 250 to rotate together. In this process, the cam portion 250 will push the valve stem 510 and make the valve stem 510 move relative to the control valve 500, so as to directly and effectively achieve the effect of driving the valve stem 510 and controlling the control valve 500.

[0033] Specifically, the valve stem 510 is installed in the mounting frame 400, and the flip member 200 and the valve stem 510 are positioned relative to each other through the mounting frame 400, thereby ensuring that when the flip member 200 rotates, the cam portion 250 can smoothly drive the valve stem 510 to move.

[0034] It is conceivable that the valve stem 510 can also be connected to the flip member 200 by threaded connection, sliding groove connection, etc., so as to achieve the control effect of the flip member 200 on the valve stem 510. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0035] In certain embodiments, reference Figure 5 The edge of the cam portion 250 is provided with an avoidance position 270, and the flip member 200 can drive the avoidance position 270 to move to overlap with the valve stem 510; the valve stem 510 is connected to a rebound member. When the flip member 200 rotates until the cam portion 250 and the valve stem 510 are staggered and the avoidance position 270 overlaps with the valve stem 510, the valve stem 510 will rebound under the action of the rebound member, so that the state of the intake pipe 100 can be quickly switched to ventilation, thereby improving the efficiency of the gas flame.

[0036] In certain embodiments, reference Figure 4 The rebound member includes a spring disposed on the control valve 500 and connected to the valve stem 510. When the valve stem 510 is pushed by the cam portion 250, the spring will be compressed and elastic potential energy will be accumulated for the spring. When the avoidance position 270 overlaps with the valve stem 510, the spring will release its elastic potential energy and achieve the effect of driving the valve stem 510 to rebound through the elastic potential energy, thereby effectively completing the rebound operation of the valve stem 510.

[0037] In certain embodiments, reference Figure 5 The cam portion 250 has an arcuate outer wall and pushes the valve stem 510 through the outer wall. When the cam portion 250 rotates, the outer wall surface will continuously rub against the valve stem 510. The arcuate outer wall can minimize the collision and jamming problems caused by the mutual friction between the valve stem 510 and the cam portion 250, thereby ensuring that the rotation of the cam portion 250 can be carried out smoothly.

[0038] In certain embodiments, reference Figure 3 The mounting frame 400 is provided with a buffer structure, and the flip member 200 is connected to the buffer structure and is hinged to the mounting frame 400 through the buffer structure. The buffer structure can reduce the impact force between the flip member 200 and the mounting frame 400 as much as possible when the flip member 200 and the mounting frame 400 are relatively rotated to the extreme position, thereby effectively reducing the damage of the flip member 200 and the mounting frame 400, thereby improving the overall service life.

[0039] In certain embodiments, reference Figure 3The buffer structure includes a damping shaft 300, and the cam portion 250 is connected to the outer periphery of the damping shaft 300 and can drive the damping shaft 300 to rotate. The damping shaft 300 can not only effectively alleviate the impact force of the mounting frame 400 and the flip member 200 when they move relative to each other, but also alleviate the relative vibration between the mounting frame 400 and the flip member 200, thereby effectively improving the stability of the flip member 200 during rotation, thereby preventing it from being damaged.

[0040] It is conceivable that the buffer structure may also be composed of other components, such as connecting the flip member 200 via a torsion spring. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0041] In certain embodiments, reference Figure 2 The cover 810 is hinged to the edge of the base 820 and can be flipped relative to the cover 810. When the cover 810 connected to the edge of the base 820 rotates, the separation between it and the base 820 can be expanded as much as possible, so that the exposure of the burner 825 can be increased as much as possible, thereby facilitating the burner 825 to perform combustion and cooking operations.

[0042] In certain embodiments, reference Figure 2 The base 820 has a cavity 827, and the burner 825 and the control valve 500 are both installed in the cavity 827; the cavity 827 has an opening, and the cover 810 can rotate to cover the opening. The cavity 827 can load and protect the burner 825 and the control valve 500, so as to ensure that the two can work smoothly and safely. In addition, after the cover 810 seals the opening of the cavity 827, it can also effectively prevent external dust, oil mist and other impurities from entering the cavity 827 and polluting the burner 825 and the control valve 500.

[0043] In certain embodiments, reference Figure 1 , control valve 500 is a cut-off valve.

[0044] The second aspect of the utility model provides an embodiment of a stove, including the above flameout mechanism. After the control valve 500 is opened and the air intake pipe 100 delivers gas to the burner 825, the burner 825 can ignite a flame so as to facilitate cooking operations through the flame. When the flame needs to be extinguished, the cover body 810 can be directly rotated to cover and shield the burner 825. At this time, the cover body 810 will drive the flip member 200 to rotate together, and the flip member 200 drives the valve stem 510 of the control valve 500 to move, so that the control valve 500 can close the ventilation state of the air intake pipe 100 through the valve stem 510, so that the flameout effect can be effectively achieved. The flameout effect can be achieved by directly rotating the cover body 810, so it has the advantage of simple operation. In addition, since the cover body 810 will make the burner 825 in a shielded state after rotation, the burner 825 can also be protected to prevent foreign impurities from entering the burner 825 and interfering with it. In addition. By judging whether the burner 825 is shielded or not, it is possible to judge whether the flame is extinguished or not. Therefore, the convenience for the user to observe whether the flame is extinguished or not can be increased as much as possible, thereby reducing the problem of forgetting to extinguish the flame or not.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
