Description

Technical Field

[0001] This utility model relates to the technical field of kitchen stoves, and in particular to a plug valve and a gas valve including the plug valve. Background Technology

[0002] In existing kitchen stove technology, the high-heat channel is generally located after the stop valve. The high-heat function can only be turned on when the stop valve is rotated to a certain angle. This method requires the user to control the adjustment angle of the stop valve, which is inconvenient for the user to turn on the high-heat mode in time. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect that the stir-fry channel is located after the stop valve in the prior art, which makes it inconvenient for users to open the stir-fry mode in time, and to provide a stop valve and a gas valve including the stop valve.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A plug valve includes a valve body and a gas inlet passage, a normal gas flow passage, a stir-fry gas flow passage, and a gas outlet passage formed inside the valve body. The outlet end of the gas inlet passage is connected to the inlet end of the normal gas flow passage and the inlet end of the stir-fry gas flow passage, respectively. The outlet end of the normal gas flow passage is connected to the inlet end of the gas outlet passage. The outlet ends of the stir-fry gas flow passage and the gas outlet passage are both used to communicate with a mixing chamber.

[0006] The valve body includes a main body and a valve cover. The gas intake channel and the stir-fry gas flow channel both penetrate the main body and the valve cover at opposite ends. The gas intake channel includes a first gas intake channel unit and a second gas intake channel unit that are connected to each other. The stir-fry gas flow channel includes a first stir-fry gas flow channel unit and a second stir-fry gas flow channel unit that are connected to each other. The first gas intake channel unit and the first stir-fry gas flow channel unit are located inside the main body, and the second gas intake channel unit and the second stir-fry gas flow channel unit are located inside the valve cover.

[0007] The plug valve further includes a first connecting channel, a first sealing ring, and a second sealing ring;

[0008] The first connecting channel is located inside the valve cover, and the two ends of the first connecting channel are respectively connected to the second gas inlet channel unit and the second stir-fry gas flow channel unit;

[0009] Both the first sealing ring and the second sealing ring are sandwiched between the main body and the valve cover. The first sealing ring is arranged around the through-hole of the first gas intake channel unit facing the valve cover, and the second sealing ring is arranged around the through-hole of the first stir-fry gas flow channel unit facing the valve cover.

[0010] In this design, the gas flow channel for stir-frying is directly connected to the gas intake channel. This means the gas entering the stir-frying gas flow channel no longer needs to pass through the stopcock valve's closure limit. Therefore, users can directly activate the stir-fry mode at any heat level, improving the user experience. This design divides the valve body into a main body and a valve cover for easy installation of the gas valve components. Since both the stopcock valve's gas intake channel and the stir-frying gas flow channel are partially located in the main body and partially in the valve cover, connected by passing through the opposite end faces of the main body and valve cover, a sealing ring is installed between the main body and the valve cover to prevent gas leakage from the gap between them, ensuring the safety of the gas valve.

[0011] Preferably, the inlet and outlet ends of the first gas intake channel unit and the inlet and outlet ends of the second gas intake channel unit both penetrate the main body and the valve cover at opposite ends.

[0012] The first sealing ring includes a first sealing ring unit and a second sealing ring unit. The first sealing ring unit is arranged around the through-hole of the first gas intake channel unit facing the valve cover, and the second sealing ring unit is arranged around the through-hole of the first gas intake channel unit facing the valve cover.

[0013] In this scheme, the inlet and outlet ends of the first gas inlet channel unit are sealed by the first sealing ring unit and the second sealing ring unit, respectively, to prevent the gas that has just flowed into the gas inlet channel from flowing directly to the outlet of the gas inlet channel, so as to control the gas to flow along the prescribed path, prevent gas leakage, and ensure the safety of the gas valve.

[0014] Preferably, the ordinary gas flow channel passes through one end face of the main body and the valve cover facing each other. The ordinary gas flow channel includes a first ordinary gas flow channel unit and a second ordinary gas flow channel unit that are connected to each other. The first ordinary gas flow channel unit is located inside the main body, and the second ordinary gas flow channel unit is located inside the valve cover.

[0015] The plug valve further includes a second connecting channel, the two ends of which are respectively connected to the inlet end of the first ordinary gas flow channel unit and the outlet end of the first gas intake channel unit. The inlet end of the first ordinary gas flow channel unit, the outlet end of the first gas intake channel unit, and the second connecting channel form an ordinary gas intake area. The second sealing ring unit is arranged around the ordinary gas intake area.

[0016] In this solution, the second sealing ring unit achieves a seal between the inlet of the ordinary gas flow channel and the outlet of the gas intake channel without affecting the gas flow between the ordinary gas flow channel and the gas intake channel.

[0017] Preferably, the first sealing ring unit, the second sealing ring unit, and the second sealing ring are integrally formed.

[0018] In this solution, the integral molding of the sealing rings eliminates gaps between them, increases the sealing area, and improves the sealing effect. Furthermore, the integral sealing rings are easier to install, avoiding the problem of difficulty in positioning multiple sealing rings.

[0019] Preferably, the end face of the first sealing ring unit facing the valve cover, the end face of the second sealing ring unit facing the valve cover, and the end face of the second sealing ring facing the valve cover are in the same plane.

[0020] In this design, the end faces of the first sealing ring unit, the second sealing ring unit, and the second sealing ring that abut against the valve cover are on the same plane. This avoids the situation where there is a step difference between the end faces of each sealing ring, which would cause gas to leak from the unsealed end face. By setting them on the same plane, the end faces of each sealing ring are sealed to the valve cover, thus improving the sealing performance between the valve cover and the main body of the plug valve.

[0021] Preferably, the second connecting channel passes through one end face of the main body and the valve cover facing each other. The second connecting channel includes a first connecting channel unit and a second connecting channel unit that are connected to each other. The first connecting channel unit is located inside the main body, and the second connecting channel unit is located inside the valve cover.

[0022] The plug valve includes a first solenoid valve, which is used to control the opening or closing of the gas intake passage. The first solenoid valve includes a first valve core, which is at least partially located within the normal gas intake area.

[0023] In this design, the ordinary gas intake area not only enables gas flow between the ordinary gas flow channel and the gas intake channel, but also provides space for the first valve core to move.

[0024] Preferably, the main body portion has a first positioning groove on one end face facing the valve cover, and the first sealing ring and the second sealing ring are accommodated in the first positioning groove at one end facing the main body portion in the thickness direction;

[0025] And / or, the valve cover has a second positioning groove on one end face facing the main body, and the first sealing ring and the second sealing ring are accommodated in the second positioning groove at one end facing the valve cover in the thickness direction.

[0026] In this design, by providing a first positioning groove and / or a second positioning groove, the first and second sealing rings are accommodated, improving the sealing performance between the valve cover and the main body. The positioning groove provides positioning for the sealing rings, facilitating installation. Furthermore, during use, the positioning groove limits the movement of the sealing rings, preventing misalignment that could affect gas flow or degrade the sealing effect.

[0027] A gas valve includes a stir-fry valve and a stopcock valve as described above. The inlet of the stir-fry valve is connected to the outlet of the stir-fry gas flow channel, and the outlet of the stir-fry valve is connected to the mixing chamber.

[0028] In this design, the mixing chamber is connected to the stop valve via a stir-fry valve. The stop valve supplies the gas required for the normal cooking mode to the mixing chamber, while the stir-fry valve supplies the gas required for the stir-fry cooking mode. Different cooking modes can be adjusted by opening or closing the stir-fry valve to adapt to more cooking scenarios.

[0029] Preferably, the stir-fry valve includes a stir-fry valve cavity, a stir-fry valve core, an inner stir-fry channel, and an outer stir-fry channel; the gas outlet channel includes an inner ring outlet channel and an outer ring outlet channel; the outlet end of the stir-fry gas flow channel is connected to the inlet of the stir-fry valve cavity; the outlet of the stir-fry valve cavity is connected to both the inner and outer stir-fry channels; the inner stir-fry channel is connected to the inner ring outlet channel; and the outer stir-fry channel is connected to the outer ring outlet channel. The stir-fry valve core is located inside the stir-fry valve cavity and can move within the stir-fry valve cavity to switch the stir-fry valve between a normal state and a stir-fry state. In the normal state, the stir-fry valve core closes either the inlet or outlet of the stir-fry valve cavity; in the stir-fry state, the inlet and outlet of the stir-fry valve cavity are connected.

[0030] In this design, the gas enters the stir-fry valve through the stir-fry gas flow channel of the stopcock valve. Since the gas outlet of the stir-fry valve chamber is connected to the inner and outer ring channels respectively, when the stir-fry valve is opened, the inner and outer ring channels are connected through the stir-fry valve chamber, thereby achieving gas communication between the inner and outer rings. This balances the gas volume in the inner and outer ring outlet channels, achieving synchronous flame for stir-frying in both the inner and outer rings, resulting in a more uniform heat distribution and improved stir-frying effect.

[0031] Preferably, the air outlet of the stir-fry valve cavity includes an independent inner ring air outlet and an outer ring air outlet. The inner ring air outlet of the stir-fry valve cavity is connected to the stir-fry inner ring channel, and the outer ring air outlet of the stir-fry valve cavity is connected to the stir-fry outer ring channel. The axis of the air inlet end of the stir-fry inner ring channel is parallel to the axis of the air inlet end of the stir-fry outer ring channel.

[0032] And / or, the inner ring channel and the outer ring channel for stir-frying are symmetrically arranged relative to the moving direction of the stir-frying valve core.

[0033] In this design, the inner and outer ring outlets of the stir-fry valve chamber are independent, allowing the gas inside the valve chamber to flow directly into the corresponding inner and outer ring channels. The axes of the inlet ends of the inner and outer ring channels are parallel, ensuring that their inlets are on the same plane. This facilitates the simultaneous sealing of both inlets with a single valve core. The symmetrical movement of the inner and outer ring channels relative to the valve core ensures that the gas flows from the valve chamber into both channels via equal paths, guaranteeing an even distribution of the gas.

[0034] The significant advantages of this invention are: the gas flow channel for stir-frying is directly connected to the gas intake channel, meaning the gas entering the stir-frying gas flow channel no longer needs to be restricted by the stopcock valve. Therefore, users can directly activate the stir-fry mode at any heat level, improving the user experience. The valve body is divided into a main body and a valve cover for easy installation of the gas valve components. Since both the gas intake channel and the stir-frying gas flow channel of the stopcock valve are partially located in the main body and partially in the valve cover, connected by passing through the opposite end faces of the main body and valve cover, a sealing ring is installed between the main body and the valve cover to prevent gas leakage from the gap between them, ensuring the safety of the gas valve.

[0074] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment as an example.

[0075] This embodiment provides a plug valve, such as Figure 1-5 As shown, it includes a valve body and a gas inlet channel 3, a normal gas flow channel, a stir-fry gas flow channel, and a gas outlet channel formed inside the valve body. The outlet end of the gas inlet channel 3 is connected to the inlet ends of the normal gas flow channel and the stir-fry gas flow channel, respectively. The outlet end of the normal gas flow channel is connected to the inlet end of the gas outlet channel. The outlet ends of the stir-fry gas flow channel and the gas outlet channel are both used to connect to the mixing chamber. The normal gas flow channel is used to flow the gas required in the normal cooking mode, and the stir-fry gas flow channel is used to flow the stir-fry gas required in the stir-fry mode.

[0076] like Figure 2 and Figure 3 As shown, the valve body includes a main body 1 and a valve cover 2. The gas intake channel 3 and the stir-fry gas flow channel both penetrate the main body 1 and the valve cover 2 at opposite ends. The gas intake channel 3 includes a first gas intake channel unit 31 and a second gas intake channel unit 32 connected to each other. The stir-fry gas flow channel includes a first stir-fry gas flow channel unit 51 and a first stir-fry gas flow channel unit 52 connected to each other. The first gas intake channel unit 31 and the first stir-fry gas flow channel unit 51 are located inside the main body 1, and the second gas intake channel unit 32 and the first stir-fry gas flow channel unit 52 are located inside the valve cover 2.

[0077] like Figure 3 and Figure 4 As shown, the stopcock valve also includes a first connecting channel 61, which is located inside the valve cover 2. The two ends of the first connecting channel 61 are respectively connected to the second gas intake channel unit 32 and the first stir-fry gas flow channel unit 52. The stir-fry gas flow channel is directly connected to the gas intake channel 3 through the first connecting channel 61. That is, the gas entering the stir-fry gas flow channel no longer flows into the ordinary gas flow channel and is limited by the stopcock valve's closure 11. Therefore, users can directly turn on the stir-fry mode at any fire level, improving the user experience.

[0078] In this embodiment, the valve body is divided into a main body 1 and a valve cover 2 to facilitate the installation of the various components of the gas valve. Since the gas inlet channel 3 and the gas flow channel for stir-frying are both partially located in the main body 1 and partially located in the valve cover 2, they are connected by penetrating the opposing end faces of the main body 1 and the valve cover 2. Therefore, this embodiment further provides a sealing ring between the main body 1 and the valve cover 2 to prevent gas leakage from the gap between the main body 1 and the valve cover 2, ensuring the safety of the gas valve in use.

[0079] Specifically, such as Figure 2 As shown, the plug valve also includes a first sealing ring 71 and a second sealing ring 72. Both the first sealing ring 71 and the second sealing ring 72 are sandwiched between the main body 1 and the valve cover 2. The first sealing ring 71 is arranged around the through-hole of the first gas intake channel unit 31 facing the valve cover 2, and the second sealing ring 72 is arranged around the through-hole of the first stir-fry gas flow channel unit 51 facing the valve cover 2.

[0080] In other embodiments, the positions of the gas intake channel 3 and the stir-fry gas flow channel in the stopcock valve are not specifically limited. For example, both the gas intake channel 3 and the stir-fry gas flow channel are located within the main body 1 and only penetrate the main body 1. In this state, only one sealing ring can be provided, which is set around the connecting area of ​​the gas intake channel 3 and the stir-fry gas flow channel.

[0081] Furthermore, such as Figures 2-4 As shown, the inlet and outlet ends of the first gas intake channel unit 31 and the inlet and outlet ends of the second gas intake channel unit 32 both penetrate the main body 1 and the valve cover 2 at opposite ends. The first sealing ring 71 includes a first sealing ring unit 711 and a second sealing ring unit 712. The first sealing ring unit 711 is arranged around the through-hole at the end of the first gas intake channel unit 31 facing the valve cover 2, and the second sealing ring unit 712 is arranged around the through-hole at the end of the first gas intake channel unit 31 facing the valve cover 2.

[0082] like Figure 3 As shown, the inlet and outlet ends of the first gas inlet channel unit 31 are sealed by the first sealing ring unit 711 and the second sealing ring unit 712, respectively, to prevent the gas that has just flowed into the gas inlet channel 3 from flowing directly to the outlet of the gas inlet channel 3, so as to control the gas to flow along the prescribed path, prevent gas leakage, and ensure the safety of the gas valve.

[0083] In this embodiment, the ordinary gas flow channel passes through the end faces of the main body 1 and the valve cover 2 facing each other. The ordinary gas flow channel includes a first ordinary gas flow channel unit 41 and a second ordinary gas flow channel unit 42 that are connected to each other. The first ordinary gas flow channel unit 41 is located inside the main body 1, and the second ordinary gas flow channel unit 42 is located inside the valve cover 2.

[0084] like Figure 3 As shown, the plug valve also includes a second connecting channel 62. The two ends of the second connecting channel 62 are respectively connected to the inlet end of the first ordinary gas flow channel unit 41 and the outlet end of the first gas intake channel unit 31. The inlet end of the first ordinary gas flow channel unit 41, the outlet end of the first gas intake channel unit 31, and the second connecting channel 62 form an ordinary gas intake area 43. The second sealing ring unit 712 is arranged around the ordinary gas intake area 43.

[0085] The second sealing ring unit 712 achieves a seal between the inlet of the ordinary gas flow channel and the outlet of the gas intake channel 3 without affecting the gas flow between the ordinary gas flow channel and the gas intake channel 3.

[0086] Specifically, such as Figure 2 As shown, the first sealing ring unit 711, the second sealing ring unit 712, and the second sealing ring 72 are integrally formed. This integral forming eliminates gaps between the sealing rings, increasing the sealing area and improving the sealing effect. Furthermore, the integral sealing rings are easier to install, avoiding the difficulty of positioning multiple sealing rings. In other embodiments, each sealing unit can also be independently configured, facilitating disassembly and individual replacement of each unit, as long as the sealing performance of the plug valve is not affected.

[0087] Furthermore, in this embodiment, the first sealing ring unit 711 and the second sealing ring unit 712 partially overlap in structure, and the first sealing ring unit 711 and the second sealing ring 72 partially overlap in structure, so as to make the overall structure of the sealing ring more compact.

[0088] In this embodiment, the end faces of the first sealing ring unit 711 facing the valve cover 2, the second sealing ring unit 712 facing the valve cover 2, and the second sealing ring 72 facing the valve cover 2 are all in the same plane. The end faces of the first sealing ring unit 711, the second sealing ring unit 712, and the second sealing ring 72 that abut against the valve cover 2 are all in the same plane. This avoids a step difference between the end faces of the sealing rings, which could cause gas leakage from unsealed end faces. By placing them in the same plane, the end faces of each sealing ring are sealed to the valve cover 2, improving the sealing performance between the valve cover 2 and the main body 1 of the stopcock valve. In other embodiments, the end face of the valve cover 2 can be configured as a non-planar structure, and the end faces of each sealing ring facing the valve cover 2 only need to be tightly attached to the valve cover 2 to prevent gas leakage.

[0089] Furthermore, the end face of the first sealing ring unit 711 facing the main body portion 1, the end face of the second sealing ring unit 712 facing the main body portion 1, and the end face of the second sealing ring 72 facing the main body portion 1 can also be in the same plane.

[0090] Furthermore, the plug valve can be provided with three methods for fixing the sealing ring by setting positioning grooves: First, the end face of the main body 1 facing the valve cover 2 is provided with a first positioning groove, and the end of the first sealing ring 71 and the second sealing ring 72 facing the main body 1 in the thickness direction is accommodated in the first positioning groove; Second, the end face of the valve cover 2 facing the main body 1 is provided with a second positioning groove 82, and the end of the first sealing ring 71 and the second sealing ring 72 facing the valve cover 2 in the thickness direction is accommodated in the second positioning groove 82; Third, both the first positioning groove and the second positioning groove 82 are provided, and the sealing ring is accommodated by the cooperation of the first positioning groove and the second positioning groove 82.

[0091] Specifically, such as Figure 3 As shown, in this embodiment, the second method is used, with only the second positioning groove 82 provided to fix the sealing ring. In other embodiments, only the first positioning groove may be provided, or both the first and second positioning grooves 82 may be provided simultaneously.

[0092] In this embodiment, by providing a first positioning groove and / or a second positioning groove 82, the first sealing ring 71 and the second sealing ring 72 are accommodated, thereby improving the sealing performance between the valve cover 2 and the main body 1. The positioning groove provides positioning for the sealing ring, facilitating installation. Furthermore, during use, the positioning groove limits the sealing ring, preventing it from shifting, which could affect gas flow and deteriorate the sealing effect. In other embodiments, positioning pins or positioning holes can also be used to position and limit the sealing ring, as long as it does not affect the sealing effect of the sealing ring on the plug valve.

[0093] In this embodiment, the second connecting channel 62 penetrates the end faces of the main body 1 and the valve cover 2 facing each other. The second connecting channel 62 includes a first connecting channel unit and a second connecting channel 62 unit that are connected to each other. The first connecting channel unit is located inside the main body 1, and the second connecting channel 62 unit is located inside the valve cover 2. The plug valve includes a first solenoid valve 12, which is used to control the opening or closing of the gas intake channel 3. The first solenoid valve 12 includes a first valve core 13, which is at least partially located within the ordinary gas intake area 43. The ordinary gas intake area 43 provides space for the first valve core 13 to move while realizing the gas flow between the ordinary gas flow channel and the gas intake channel 3.

[0094] The specific structure of the first solenoid valve 12 and how it opens or closes the gas intake channel 3 are existing technologies in this field and will not be described in detail here.

[0095] This embodiment provides a gas valve, such as Figure 1 and Figure 6 As shown, the gas valve includes a stir-fry valve 10 and the aforementioned stopcock valve. The inlet of the stir-fry valve 10 is connected to the outlet of the stir-fry gas flow channel, and the outlet of the stir-fry valve 10 is connected to the mixing chamber. The mixing chamber is connected to the stopcock valve via the stir-fry valve 10. The stopcock valve supplies the gas required for the normal cooking mode to the mixing chamber, while the stir-fry valve 10 supplies the gas required for the stir-fry cooking mode to the mixing chamber. Different cooking modes can be adjusted by opening or closing the stir-fry valve 10 to adapt to more cooking scenarios.

[0096] Among them, such as Figure 6 As shown, the stir-fry valve 10 includes a stir-fry valve chamber 101, a stir-fry valve core 102, a stir-fry inner ring channel 103, and a stir-fry outer ring channel 104. The gas outlet channel includes an inner ring outlet channel 91 and an inner ring outlet channel 92. The outlet end of the stir-fry gas flow channel is connected to the inlet of the stir-fry valve chamber 101. The outlet of the stir-fry valve chamber 101 is connected to the stir-fry inner ring channel 103 and the stir-fry outer ring channel 104, respectively. The stir-fry inner ring channel 103 is connected to the inner ring outlet channel 91, and the stir-fry outer ring channel 104 is connected to the inner ring outlet channel 92. The stir-fry valve core 102 is located inside the stir-fry valve chamber 101 and can move within the stir-fry valve chamber 101 to switch the stir-fry valve 10 between a normal state and a stir-fry state.

[0097] In normal conditions, the stir-fry valve core 102 closes the air inlet or air outlet of the stir-fry valve chamber 101; in the stir-frying state, the air inlet and air outlet of the stir-fry valve chamber 101 are connected.

[0098] Gas enters the stir-fry valve 10 through the stir-fry gas flow channel of the stopcock valve. Since the gas outlet of the stir-fry valve chamber 101 is connected to the inner ring channel 103 and the outer ring channel 104 respectively, when the stir-fry valve 10 is opened, the inner ring channel 103 and the outer ring channel 104 are connected through the stir-fry valve chamber 101, thereby realizing the gas connection between the inner and outer rings, balancing the gas volume of the inner ring gas outlet channel 91 and the inner ring gas outlet channel 92, realizing the synchronous fire of the inner and outer rings, making the fire distribution more uniform and improving the stir-frying effect.

[0099] In this embodiment, the stir-fry valve is a manual valve. Specifically, as shown... Figure 6 As shown, the upper end of the valve stem 109 of the stir-fry valve extends to the top of the cooktop panel, and the lower end of the valve stem 109 is connected to the stir-fry valve core 102. Users can directly press the valve stem 109 to move the stir-fry valve core 102 vertically. A magnet 106 is located at the bottom of the stir-fry valve core 102, and an electromagnet 105 is located below the stir-fry valve core 102, inside the stir-fry valve cavity 101. When the electromagnet 105 is energized, it can attract the stir-fry valve core 102; when the electromagnet 105 is de-energized, it can release the stir-fry valve core 102.

[0100] like Figure 6 As shown, a fixed frame 107 is connected to the inner bottom of the valve cavity. An electromagnet 105 is disposed inside the fixed frame 107 and is connected to the stir-fry valve core 102 through the valve stem 109. An elastic element 108 is disposed between the stir-fry valve core 102 and the fixed frame 107. The elastic element 108 provides upward pressure to the stir-fry valve core 102 to achieve the reset of the stir-fry valve core 102.

[0101] In other embodiments, the stir-fry valve can also be other types of valves, such as solenoid valves, strong suction valves, etc., as long as they can achieve the above functions.

[0102] In this embodiment, the gas outlet of the stir-fry valve chamber 101 includes an independent inner ring gas outlet and an outer ring gas outlet. The inner ring gas outlet of the stir-fry valve chamber 101 is connected to the inner ring channel 103, and the outer ring gas outlet of the stir-fry valve chamber 101 is connected to the outer ring channel 104. The axis of the air inlet end of the inner ring channel 103 and the axis of the air inlet end of the outer ring channel 104 are parallel. The inner ring gas outlet and the outer ring gas outlet of the stir-fry valve chamber 101 are independent of each other, so that the gas inside the stir-fry valve chamber 101 can directly flow into the corresponding inner ring channel 103 and outer ring channel 104. The axis of the air inlet of the inner ring channel 103 is parallel to the axis of the air inlet of the outer ring channel 104, so that the air inlet of the inner ring channel 103 and the air inlet of the outer ring channel 104 are in the same plane, which makes it convenient to block the air inlet of the inner ring channel 103 and the air inlet of the outer ring channel 104 at the same time through a single stir-fry valve core 102.

[0103] In other embodiments, the gas outlet of the stir-fry valve chamber 101 may be provided as only one, and the gas flows out of the stir-fry valve chamber 101 and is then diverted into the stir-fry inner ring channel 103 and the stir-fry outer ring channel 104.

[0104] The inner ring channel 103 and the outer ring channel 104 are symmetrically arranged with respect to the moving direction of the stir-fry valve core 102. This symmetry ensures that the flow paths from the stir-fry valve cavity 101 into the inner ring channel 103 and the outer ring channel 104 are equal, guaranteeing an even distribution of gas.

[0105] In other embodiments, the setting of the inner ring channel 103 and the outer ring channel 104 for stir-frying is not specifically limited, as long as they can cooperate with the stir-fry valve core 102 to realize the switching of the stir-fry valve 10 between the normal state and the stir-frying state.
