Description

Technical Field

[0001] The present invention relates to the technical field of gas stoves, and in particular to a stage valve and a gas stove comprising the same. Background Art

[0002] With the continuous development of life, more and richer ingredients are entering people's tables. The different cooking methods of different ingredients have led to more and more diverse demands for gas stoves by users. These demands are mainly for the gas control in gas stoves. For example, some ingredients need to be stir-fried during the cooking process, and the thermal efficiency required for stir-frying is higher than that required for normal cooking. That is to say, the firepower of the gas stove needs to be suddenly transformed from normal cooking firepower to the firepower required for stir-frying, so as to meet the user's demand for stir-frying ingredients.

[0003] In the prior art, a strong suction valve is generally used to enable a gas stove to enter a stir-frying state. The strong suction valve is arranged in the outer ring channel of the gas stove valve body. By connecting the strong suction valve, the area available for gas circulation in the outer ring channel is instantly increased, thereby achieving the effect of instantly entering the stir-frying state during normal cooking. However, this strong suction valve has the following drawbacks: First, because the strong suction valve is only arranged in the outer ring channel, its effect on gas interception is limited, and it mainly realizes the function of returning the outer ring fire cover to the maximum flame; second, the strong suction valve arranged in the outer ring channel cannot simultaneously increase the flame power of the inner ring fire cover and the outer ring fire cover; third, the gas interception is mainly at the gas nozzle, and simply increasing the gas flow area in the outer ring channel has a limited effect on increasing the gas stove's flame power. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the stir-frying firepower in the stir-frying mode is not significantly improved, and to provide a stage valve and a gas stove containing the same.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A section valve, comprising an air inlet channel and an air outlet channel, wherein the air inlet channel is arranged between the air inlet of the section valve and the closure of the section valve, and the air outlet channel is arranged between the closure and the air outlet of the section valve. The section valve also comprises a stir-frying channel and a stir-frying switch, wherein the two ends of the stir-frying channel are respectively connected to the air inlet channel and the air outlet channel, the stir-frying switch is arranged corresponding to the stir-frying channel, and the stir-frying switch is used to control the opening or closing of the stir-frying channel.

[0007] In this solution, an additional stir-fry channel is provided to increase the amount of gas entering the air outlet channel, thereby increasing the amount of gas flowing out through the air outlet channel to the burner connected to the section valve accordingly, and the firepower of the burner is instantly increased, that is, the stir-fry mode is entered. Compared with the strong suction valve controlling the flow area in the outer ring channel, the increase in the amount of gas to increase the firepower of the burner is more effective. The stir-fry channel is also provided with a stir-fry switch, which is used to control the opening or closing of the stir-fry channel. When the stir-fry channel is open, the amount of gas provided to the burner by the section valve increases, and the increase in the amount of gas entering the burner causes all fire holes of the burner to burn fully, thereby realizing the stir-fry mode. When the stir-fry channel is closed, the amount of gas in the air outlet channel of the section valve returns to the normal gas amount in the fire adjustment state, and the firepower of the burner connected thereto is also determined by the rotation angle of the gas knob of the section valve.

[0008] Preferably, the gas outlet channel includes an inner ring gas channel and an outer ring gas channel, a first outlet is formed between the stir-fry channel and the inner ring gas channel, and a second outlet is formed between the inner ring gas channel and the outer ring gas channel, and the first outlet and the second outlet are both opened or closed by the stir-fry switch.

[0009] In this scheme, the gas outlet channel includes an inner ring gas channel and an outer ring gas channel. The stir-fry channel is connected to the inner ring gas channel and forms a first outlet. When the stir-fry channel is turned on by the stir-fry switch, the amount of gas entering the inner ring gas channel through the stir-fry channel increases accordingly. At the same time, the inner ring gas channel is also connected to the outer ring gas channel and forms a second outlet. When the stir-fry channel is turned on, the amount of gas entering the inner ring gas channel increases and synchronously enters the outer ring gas channel through the second outlet. That is to say, when the stir-fry switch is turned on, the amount of gas entering the outer ring gas channel also increases accordingly, so that all the fire holes of the burner connected to the section valve can achieve full combustion to realize the stir-fry mode. At this time, the inner ring gas channel and the outer ring gas channel are connected to each other through the second outlet, and turning the gas knob of the section valve will not affect the firepower of the burner connected to the section valve. The inner ring gas channel and the outer ring gas channel maintain synchronized gas volume, and accordingly, the various fire holes of the burner maintain synchronized firepower.

[0010] Preferably, the stir-fry switch is electrically connected to a solenoid valve, and the solenoid valve is used to synchronously open or close the first outlet and the second outlet.

[0011] In this solution, the stir-fry switch is electrically connected to the solenoid valve to realize one-button opening or closing of the stir-fry channel, and the solenoid valve can synchronously open the first outlet and the second outlet, thereby saving the number of solenoid valves and improving the synchronization of opening or closing the first outlet and the second outlet, avoiding the situation where the gas volume in the inner ring gas channel and the gas volume in the outer ring gas channel are different in the stir-fry mode because the second outlet has not yet been opened.

[0012] Preferably, the first outlet and the second outlet are coaxially arranged, and the solenoid valve is provided with a moving shaft which extends into the second outlet and the first outlet in sequence and reciprocates along the axial direction of the first outlet, and the moving shaft is provided with a first seal and a second seal corresponding to the first outlet and the second outlet respectively.

[0013] In this solution, the first outlet and the second outlet are coaxially arranged so that the moving axis of the solenoid valve extends into the first outlet and the second outlet in sequence along the axial direction to achieve synchronous opening or closing of the stir-frying channel and the second outlet.

[0014] Preferably, the end portion of the first sealing member extending into the first outlet is tapered.

[0015] In this solution, the end of the first seal is configured to be conical so that when the end is inserted into the first outlet and contacts the first outlet through the conical surface, it provides a guiding effect for the first seal to extend into the first outlet, thereby improving the sealing performance of the first seal for the first outlet and the success rate of the first seal extending into the first outlet.

[0016] Preferably, the size of the first outlet is smaller than that of the second outlet.

[0017] In this solution, the size of the first outlet is smaller than that of the second outlet, so as to facilitate the processing of the first outlet and the second outlet when the first outlet and the second outlet are coaxially arranged.

[0018] Preferably, the air inlet passage is further provided with an air inlet valve and an air inlet cavity connected to the shutter, the air inlet cavity is connected to the air inlet valve, one end of the stir-frying passage is connected to the air inlet cavity, and the other end of the stir-frying passage is connected to the air outlet passage; or, one end of the stir-frying passage is connected to the outlet of the air inlet valve and the other end of the stir-frying passage is connected to the air outlet passage.

[0019] In this solution, the sealing of the stir-frying channel is controlled by the stir-frying switch, and the air intake valve connected to the air intake chamber ensures the sealing of the closure through the valve cover of the air intake valve, thereby ensuring the smooth opening and closing of the stir-frying channel while improving the safety of the stir-frying channel and the section valve; or, the stir-frying channel is connected to the outlet of the air intake valve so that the stir-frying channel and the air intake valve share the valve cover of the air intake valve, thereby improving the sealing of the stir-frying channel and the section valve while saving the need to set up an additional sealing structure for the stir-frying channel and improving the safety of the section valve.

[0020] Preferably, one end of the stir-frying channel is connected to the shutter, and the other end of the stir-frying channel is connected to the air outlet channel. The shutter is provided with a stir-frying flow hole corresponding to the stir-frying channel.

[0021] In this solution, one end of the stir-frying channel can also be directly connected to the closure, and a stir-frying flow hole is provided on the closure corresponding to the stir-frying channel. When the stir-frying flow hole is connected to the stir-frying channel, the gas enters the inner ring gas channel and the outer ring gas channel in turn through the stir-frying channel and correspondingly increases the firepower of the burner connected to the section valve. Sealing the stir-frying channel through the closure not only requires less structural modification of the section valve, lowers the cost and improves the sealing effect accordingly.

[0022] Preferably, the section valve is further provided with a third sealing member, which is provided corresponding to the opening of the stir-frying channel and is located between the cover body and the valve body of the section valve.

[0023] In this solution, the stir-frying channel is correspondingly arranged on the valve body, and an opening is formed due to processing reasons. A cover body is provided to improve the sealing performance. The cover body is used to cover the opening. A third sealing member is further provided at the corresponding opening between the cover body and the valve body to improve the sealing performance of the valve body, thereby improving the safety of the use of the section valve.

[0024] A gas stove comprises the above-mentioned stage valve.

[0025] In this solution, the gas stove includes the above-mentioned stage valve. The use of the above-mentioned stage valve can not only enable the gas stove to quickly enter the stir-fry mode, but also achieve stir-frying by increasing the amount of gas, which can make the gas stove's firepower greater than that of a gas stove that changes the gas flow area in the gas channel, and the stir-frying effect is better. Moreover, the connection between the inner ring gas channel and the outer ring gas channel can also enable the inner ring fire cover and the outer ring fire cover of the gas stove to achieve the effect of synchronized firepower.

[0026] The positive progress of the present invention is that: by additionally providing a stir-fry channel and controlling the opening or closing of the stir-fry channel through a stir-fry switch, the present invention can quickly increase the amount of gas into the outlet channel of the section valve, thereby increasing the amount of gas ejected from the outlet channel, thereby enabling the burner connected to the section valve to quickly enter the stir-fry mode during combustion. Moreover, when the burner enters the stir-fry mode, because a second outlet is provided between the inner ring gas channel and the outer ring gas channel of the section valve so that the gas can also flow from the inner ring gas channel to the outer ring gas channel when the stir-fry channel is opened, the amount of gas ejected from the outlet channel of the section valve remains consistent and increases compared to when the stir-fry channel is not opened, that is, in the stir-fry mode, the synchronous firepower of the inner ring fire cover and the outer ring fire cover of the burner connected to the section valve can also be achieved.

[0053] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0054] Example 1

[0055] This embodiment provides a segment valve, the specific structure of which is as follows Figure 1 、 Figure 2 and Figure 3 As shown, it includes a valve body 1, an air inlet channel 2 and an air outlet channel 3 are arranged in the valve body 1, the valve body 1 is provided with an air inlet 11, the air inlet 11 is connected to the gas source and supplies gas to the air inlet channel 2, a closure 12 is also provided in the valve body 1, the two ends of the air inlet channel 2 are respectively connected to the air inlet 11 and the closure 12, a plurality of flow holes are provided on the closure 12, and the valve stem of the valve body 1 is driven to rotate so that the flow holes are correspondingly connected and gas is supplied to the air outlet channel 3 connected to the closure 12, the two ends of the air outlet channel 3 are respectively connected to the closure 12 and the air outlet of the section valve, the gas flows out through the air outlet channel 3 and further flows to the burner connected to the section valve, thereby making the inner ring fire cover and the outer ring fire cover of the burner burn normally. This is the existing technology and will not be elaborated here. In addition, the section valve also includes a stir-fry channel 4 and a stir-fry switch (not shown in the figure). The two ends of the stir-fry channel 4 are respectively connected to the air inlet channel 2 and the air outlet channel 3, and the stir-fry switch is set corresponding to the stir-fry channel 4, and the stir-fry switch is used to control the opening or closing of the stir-fry channel 4. When the stir-fry switch turns on the stir-fry channel 4, the gas flows into the stir-fry channel 4 through the air inlet channel 2 and flows to the air outlet channel 3 through the stir-fry channel 4. Compared with the amount of gas flowing to the air outlet channel 3 through the closure 12 alone, the amount of gas flowing out of the air outlet channel 3 is increased. By increasing the amount of gas flowing out of the air outlet channel 3, the amount of gas flowing out of the air outlet channel 3 to the burner connected to the section valve is correspondingly increased, and the firepower of the burner is instantly increased, that is, the stir-fry mode is entered. When the stir-fry switch closes the stir-fry channel 4, the gas only flows to the air inlet channel 2 through the air inlet 11 and flows to the closer 12 and the air outlet channel 3 in turn. At this time, the section valve provides the amount of gas required to achieve the normal firepower of the burner, and directly increases the amount of gas flowing out of the air outlet channel 3. Compared with the prior art of controlling the flow area in the outer ring channel by the strong suction valve, it is more effective to directly increase the gas outflow and enhance the firepower of the burner. In addition, directly controlling the increase or decrease of the amount of gas flowing out of the section valve through the stir-fry switch can make the burner connected to the section valve faster and more timely when entering or exiting the stir-fry mode, thereby improving the user experience in actual use.

[0056] like Figure 4As shown, the air intake passage 2 is also provided with an air intake valve 8 and an air intake chamber 9 which are connected to the closure 12, wherein one end of the air intake chamber 9 is connected to the air intake passage 2, and the other end of the air intake chamber 9 is connected to the air intake valve 8. The air intake valve 8 is a valve body used to supply gas to the closure 12 in the prior art. No more details are given here. The air intake valve 8 is provided with a valve cover, and the outlet of the air intake valve 8 is connected to the closure 12. The air intake valve 8 is opened or closed by the valve cover to supply gas to the closure 12. In addition, one end of the stir-frying channel 4 is located on one side of the air intake chamber 9 and is connected to the air intake passage 2, that is, the gas flowing in through the air intake passage 2 flows to the air intake chamber 9 and the stir-frying channel 4 respectively. The sealing of the stir-frying channel 4 is controlled by the stir-frying switch, and the air intake valve 8 connected to the air intake chamber 9 ensures the sealing of the closure 12 through the valve cover of the air intake valve 8, which improves the safety of the stir-frying channel 4 and the stage valve while ensuring the smooth opening and closing of the stir-frying channel 4.

[0057] At the same time, if Figure 3 and Figure 5As shown, the gas outlet channel 3 includes an inner ring gas channel 31 and an outer ring gas channel 32. One end of the inner ring gas channel 31 and the outer ring gas channel 32 are both connected to the closure 12, and the other ends of the inner ring gas channel 31 and the outer ring gas channel 32 are used to communicate with the burner and supply gas to the inner ring fire cover and the outer ring fire cover of the burner respectively. In this embodiment, the stir-frying channel 4 is a rectangular groove opened on the valve body 1. The rectangular groove is adjacent to the inner ring gas channel 31 and the outer ring gas channel 32. One end of the stir-frying channel 4 is connected to the inner ring gas channel 31 and the outer ring gas channel 32. The first and second outlets 41 and 5 are both opened or closed by the stir-fry switch. When the stir-fry channel 4 is turned on, the gas flows from the first outlet 41 into the inner gas channel 31 through the stir-fry channel 4, and flows into the outer gas channel 32 through the second outlet 5. At this time, the amount of gas flowing out of the inner gas channel 31 and the outer gas channel 32 increases, while the inner gas channel 31 and the outer gas channel 32 are in a connected state with each other, thereby making the amount of gas flowing out of the inner gas channel 31 and the outer gas channel 32 consistent. That is to say, when the stir-fry switch is turned on, the amount of gas entering the outer gas channel 32 and the amount of gas in the inner gas channel 31 increase, flow out of the stage valve and realize the stir-fry mode of the burner, and the second outlet 5 opened by the stir-fry switch makes the gas in the inner gas channel 31 and the gas in the outer gas channel 32 mixed. At this time, rotating the valve stem or gas knob of the stage valve will not affect the gas volume in the inner ring gas channel 31 and the outer ring gas channel 32 and the fire power of the burner connected to the stage valve. The inner ring gas channel 31 and the outer ring gas channel 32 maintain synchronous gas volume. Accordingly, the inner ring fire cover and the outer ring fire cover of the burner realize the stir-fry mode and the various fire holes of the inner ring fire cover and the outer ring fire cover realize synchronous fire power increase, without increasing the fire power of the inner ring fire cover or the outer ring fire cover alone, that is, the inner ring fire cover and the outer ring fire cover are in a synchronous fire power state.

[0058] In this embodiment, the stir-fry switch is electrically connected to the solenoid valve 6 and is located on one side of the stage valve. The solenoid valve is provided with a moving shaft that can move back and forth, and the first outlet 41 and the second outlet 5 in the valve body 1 are coaxially arranged. The moving shaft of the solenoid valve 6 is used to synchronously open or close the first outlet 41 and the second outlet 5.

[0059] Specifically, the stir-fry passage 4 is a rectangular slot within the valve body 1. A connecting slot is provided on one side of the stir-fry passage 4, connecting the inner ring gas passage 31 and the stir-fry passage 4. One end of the connecting slot communicates with the inner ring gas passage 31, and the other end communicates with the stir-fry passage 4. A first outlet 41 is located at the junction of the connecting slot and the stir-fry passage 4. Furthermore, a mixing slot is provided between the inner ring gas passage 31 and the outer ring gas passage 32. The mixing slot is located on one side of the connecting slot and spaced apart from the connecting slot. A second outlet 5 is provided between the mixing slot and the connecting slot. This spacing prevents the motion axis of the solenoid valve 6 from blocking the flow of gas to the mixing slot when gas enters the connecting slot, thereby reducing the amount of gas entering the mixing slot. This ensures sufficient gas enters the outer ring gas passage 32. Furthermore, the first outlet 41 and the second outlet 5 are coaxially arranged. The motion axis of the solenoid valve 6 extends into the second outlet 5 and the first outlet 41, respectively, and reciprocates along the axis of the first outlet 41, synchronously opening the first outlet 41 and the second outlet 5. By using the solenoid valve to synchronously open the first outlet 41 and the second outlet 5, the number of solenoid valves 6 set can be reduced, and the cost of the segment valve can be reduced. In addition, compared with setting two battery valves 6 for the first outlet 41 and the second outlet 5 respectively and controlling their opening or closing, the synchronization of the same solenoid valve 6 in opening or closing the first outlet 41 and the second outlet 5 is correspondingly improved, avoiding the situation in which the gas volume in the inner ring gas channel 31 and the gas volume in the outer ring gas channel 32 are different due to the second outlet not being opened in the stir-frying mode, thereby ensuring the synchronous firepower of the burner connected to the segment valve.

[0060] In addition, a first seal 61 and a second seal 62 are provided on the moving shaft of the solenoid valve. The first seal 61 is provided corresponding to the first outlet 41 and is located at the end of the moving shaft away from the solenoid valve 6 body. The second seal 62 is sleeved on the moving shaft and the second seal 62 is located between the first seal 61 and the solenoid valve 6 body. The second seal 62 is provided corresponding to the second outlet 5. The material of the first seal 61 and the second seal 62 is the rubber material in the prior art, so as to improve the sealing performance of the first outlet 41 and the second outlet 5.

[0061] Specifically, a first seal 61 is fixedly connected to the end of the motion shaft and is provided with a snap-fit groove. A protrusion is provided at the end of the motion shaft corresponding to the snap-fit groove. The protrusion snaps into the snap-fit groove to prevent the first seal 61 from falling out when the first seal 61 extends into the first outlet 41 for sealing. A second seal 62 is sleeved on the motion shaft and is larger than the second outlet 5. The second seal 62 is configured to cover the edge of the second outlet 5 to seal the second outlet 5. Furthermore, an elastic member is sleeved on the motion shaft to provide the elastic force for the second seal 62 to approach the second outlet 5. The elastic member can be a spring as known in the art. A limiter is also provided on the motion shaft. The limiter is provided on the side of the second seal 62 adjacent to the first seal 61. The second seal 62 is provided with a limiter groove corresponding to the limiter groove. The limiter groove is configured to snap into the limiter groove to restrict the second seal 62 from approaching the first seal 61 under the elastic force of the elastic member, thereby ensuring smooth opening and closing of the second outlet 5.

[0062] Furthermore, the end of the first sealing member 61 extending into the first outlet 41 is configured to be tapered.

[0063] Specifically, the first outlet 41 is a circular hole, and the first sealing member 61 is a cylindrical structure. The surface of the cylindrical structure that contacts the hole wall of the first outlet 41 is conically set, that is, the size of the end of the cylindrical structure extending into the first outlet 41 is smaller than the size of the end away from the first outlet 41. In this way, when the first sealing member 61 extends into the first outlet 41, the conical surface contacts the first outlet 41, providing a guiding effect for the first sealing member 61 to extend into the first outlet 41, thereby improving the sealing performance of the first sealing member 61 for the first outlet 41 and the success rate of the first sealing member 61 extending into the first outlet 41.

[0064] In this embodiment, the second outlet 5 is also a circular hole, and the size of the second outlet 5 is larger than that of the first outlet 41. Figure 5 As shown, when the solenoid valve 6 simultaneously opens the first outlet 41 and the second outlet 5, the moving shaft contracts along the axis of the first outlet 41, and the first sealing member 61 moves from the first outlet 41 into the connecting groove. The second sealing member 62 also moves closer to the body of the solenoid valve 6. By setting the size of the second outlet 5 larger than that of the first outlet 41, the gas flowing through the first outlet 41 can avoid being intercepted by the first sealing member 61 when flowing to the second outlet 5, thereby ensuring that a sufficient amount of gas enters the outer ring gas channel 32 through the second outlet 5. In addition, the size of the first outlet 41 is set to be smaller than that of the second outlet 5. This facilitates the coaxial arrangement of the first outlet 41 and the second outlet 5 when they are simultaneously machined on one side of the valve body 1, while ensuring ease of machining.

[0065] like Figure 4As shown, in this embodiment, the section valve is further provided with a third sealing member 7. The material of the third sealing member 7 is also the rubber in the prior art. The third sealing member 7 is provided on the valve body 1 and the cover body for covering the stir-frying channel 4 and the openings of the connecting groove and the mixing groove on the valve body 1. The shape of the third sealing member 7 is consistent with the shape of the cover body, and the third sealing member 7 is provided with an opening consistent with the shape of the opening of the stir-frying channel 4 and the connecting groove and the mixing groove. Therefore, the provision of the third sealing member 7 will not reduce the flow area for gas circulation in the stir-frying channel 4 and the connecting groove and the mixing groove, which not only improves the sealing performance of the section valve, but also can avoid safety problems caused by gas leakage.

[0066] The present embodiment also provides a gas stove, which includes the above-mentioned stage valve. The use of the above-mentioned stage valve can not only enable the gas stove to quickly enter the stir-fry mode, but also the gas stove supplies gas to the inner ring gas channel 31 through the stir-fry channel 4 to increase the gas amount to achieve stir-frying, which can make the gas stove have greater firepower and better stir-frying effect than the gas stove that changes the gas flow area in the gas channel. Moreover, the inner ring gas channel 31 is connected to the outer ring gas channel 32, which can also achieve the effect of synchronized firepower of the inner ring fire cover and the outer ring fire cover of the gas stove, thereby meeting the different fire requirements of users and improving the firepower range of the gas stove.

[0067] Example 2

[0068] The structure of the segment valve in this embodiment is roughly the same as that in embodiment 1, except that Figure 6 As shown, one end of the stir-frying channel 4 is connected to the outlet of the air inlet valve 8 and the other end of the stir-frying channel 4 is connected to the air outlet channel 3.

[0069] Specifically, an air intake chamber 9 is provided in the air intake channel 2, and the air intake chamber 9 is connected to the air intake valve 8. One end of the stir-frying channel 4 is connected to the outlet of the air intake valve 8, but is not directly connected to the air intake channel 2. The gas enters the valve body 1 through the air intake port 11 and flows into the air intake valve 8 through the air intake channel 2 and the air intake chamber 9 in turn. When the valve cover of the air intake valve 8 is opened, the gas flows to the closure 12 and the stir-frying channel 4. When the air intake valve 8 is closed, the gas cannot flow to the closure 12 and the stir-frying channel 4. The stir-frying channel 4 is connected to the outlet of the air intake valve 8 so that the stir-frying channel 4 and the air intake valve 8 share the valve cover of the air intake valve 8 for sealing, and the stir-frying channel 4 is also provided with a stir-frying switch for opening or closing the stir-frying channel 4. By increasing the number of sealing structures for the stir-frying channel 4 to further improve the sealing performance of the section valve, and the closure 12 and the stir-frying channel 4 share the air intake valve 8 for sealing, it is also possible to increase the number of sealing structures while avoiding the problem of increased manufacturing cost of the section valve caused by increasing the number of sealing structures.

[0070] Example 3

[0071] The structure of the segment valve in this embodiment is roughly the same as that in embodiment 1, except that Figure 7 、 Figure 8 As shown, one end of the stir-frying channel 4 is connected to the shutter 12 , and the other end of the stir-frying channel 4 is connected to the air outlet channel 3 . The shutter 12 is provided with a stir-frying flow hole 121 corresponding to the stir-frying channel 4 .

[0072] Specifically, one end of the stir-fry channel 4 is connected to the accommodating area of the valve body 1 for accommodating the shutter 12, and a stir-fry flow hole 121 is provided on the shutter 12 corresponding to the stir-fry channel 4. When the user needs to enter the stir-fry mode, he only needs to turn the valve stem or gas knob of the valve body 1 to make the stir-fry flow hole 121 connected to the stir-fry channel 4, and the stir-fry channel 4 is sealed by the valve body 1 and the shutter 12, and then the stir-fry channel 4 is sealed for the second time through the stir-fry switch. Compared with the method of setting the air intake chamber 9 and the air intake valve 8 and allowing the shutter 12 and the stir-fry channel 4 to share the sealing structure, the stir-fry channel 4 is sealed by the shutter 12, and the processing steps for the valve body 1 are fewer, and the modification cost of the valve body 1 is correspondingly reduced. While increasing the number of sealing structures for the stir-fry channel 4, the manufacturing cost of the section valve is further reduced.

[0073] In addition, in the present embodiment, in order to ensure the sealing effect of the stir-frying channel 4, the setting angle of the stir-frying flow hole 121 needs to be greater than the setting angle of the inner ring flow hole in the closer 12. That is to say, when the closer 12 is rotated to the inner ring flow hole, the stir-frying flow hole 121 is not connected to the stir-frying channel 4, and the stir-frying channel 4 is still in a sealed state at this time. In the present embodiment, the setting angle of the stir-frying flow hole 121 is 60°. Of course, it can also be set to other angles in other embodiments. The purpose is to avoid the stir-frying channel 4 from opening when the amount of gas flowing out of the inner ring flow hole is low, thereby causing the burner connected to the stage valve to "explode" or other safety problems, so as to ensure the user's safety and usage experience.

[0074] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
