[0006] The first gas channel has a valve port communicated with the wok frying inlet channel and the wok frying outlet channel, the wok frying valve core is arranged in the first gas channel and can move relative to the wok frying valve body to open or close the valve port, so that the wok frying valve is switched between an ordinary state and a wok frying state,

[0007] In the ordinary state, the wok frying valve core closes the valve port, and the wok frying inlet channel and the wok frying outlet channel are communicated through the second gas channel,

[0008] In the wok frying state, the wok frying valve core opens the valve port.

[0009] In the present scheme, when the wok-searing valve core closes the valve port, the wok-searing valve is in the normal state, the second gas passage communicates the wok-searing inlet passage and the wok-searing outlet passage, the gas flows through the second gas passage, the gas supply is small, the gas flow into the ejector pipe is small, which is suitable for the normal cooking state.

[0014] Preferably, the second gas passage penetrates to the valve port.

[0015] In the present scheme, the second gas passage directly penetrates the valve port, so that when the wok-searing valve is in the wok-searing state, the valve port and the port of the second gas passage jointly form an opening with a larger size for the gas flow, reducing the resistance of the gas flow, making the gas flow more smooth, and improving the wok-searing effect of the wok-searing valve.

[0021] In this scheme, another forming mode of the second gas passage is provided. By arranging a protruding portion on the popping valve body, the moving stroke of the popping valve core is shortened. The second gas passage is directly formed on the peripheral side wall of the protruding portion, and the structure of the popping valve core does not need to be improved.

[0022] Preferably, along the extension direction of the protruding portion, the protruding portion comprises a first protruding unit and a second protruding unit, the first protruding unit is connected with the inner side wall of the first gas passage, and the second protruding unit is arranged at one end of the first protruding unit facing the popping valve core; the second gas passage is arranged on the peripheral side wall of the second protruding unit, and the wall thickness of the peripheral side wall of the second protruding unit is smaller than the wall thickness of the peripheral side wall of the first protruding unit.

[0056] The utility model will be described in detail below with reference to the preferred embodiments and drawings.

[0057] Embodiment

[0058] The embodiment provides a stove, such as Figure 1 and Figure 5 As shown, the stove comprises a stir-frying valve 100, a plug valve 200 and an ejector pipe 300. The plug valve 200 comprises an inner ring gas outlet passage 210 and an outer ring gas outlet passage 220, and the ejector pipe 300 comprises an inner ring ejector pipe 310 and an outer ring ejector pipe 320. The stir-frying valve 100 is connected between the inner ring gas outlet passage 210 of the plug valve 200 and the inner ring ejector pipe 310, so as to realize the inner ring stir-frying function.

[0059] Specifically, as shown in Figures 1-5 The stir-frying valve 100 comprises a stir-frying valve body 110 and a stir-frying valve core 120. The inside of the stir-frying valve body 110 forms a stir-frying gas inlet passage 130, a stir-frying gas outlet passage 140, a first gas passage 150 and a second gas passage 160. The inner ring gas outlet passage 210 in the plug valve 200 is in communication with the stir-frying gas inlet passage 130 of the stir-frying valve 100, the stir-frying gas outlet passage 140 of the stir-frying valve 100 is in communication with the inner ring ejector pipe 310, and the outer ring gas outlet passage 220 of the plug valve 200 is directly in communication with the outer ring ejector pipe 320.

[0060] The second gas passage 160 is in communication with the wok burning inlet passage 130 and the wok burning outlet passage 140, the first gas passage 150 has a valve port 170 in communication with the wok burning inlet passage 130 and the wok burning outlet passage 140, the wok burning valve core 120 is arranged in the first gas passage 150 and can move relative to the wok burning valve body 110 to open or close the valve port 170, so as to switch the wok burning valve 100 between the normal state and the wok burning state.

[0061] In the normal state, the wok burning valve core 120 closes the valve port 170, the wok burning inlet passage 130 and the wok burning outlet passage 140 are only in communication through the second gas passage 160, the gas flows through the second gas passage 160, the gas supply amount is small, so that the gas flow flowing into the ejector pipe 300 is small, which is suitable for the normal cooking state.

[0062] In the wok burning state, the wok burning valve core 120 opens the valve port 170, the first gas passage 150 is opened, the gas flows through the first gas passage 150 and the second gas passage 160 at the same time, the gas supply amount is large, so that the gas flow flowing into the ejector pipe 300 is large, which realizes the wok burning function.

[0063] In the embodiment, the normal state and the wok burning state share one gas passage, without the need to additionally set a separate wok burning passage, which simplifies the corresponding connection structure of the wok burning valve 100, has a smaller size, does not occupy too much space, and effectively improves the user's use experience.

[0064] In the embodiment, the valve port 170 is arranged between the first gas passage 150 and the wok burning outlet passage 140, one end of the second gas passage 160 is in communication with the first gas passage 150, and the other end of the second gas passage 160 is in communication with the wok burning outlet passage 140. The second gas passage 160 is in communication with the wok burning inlet passage 130 through the first gas passage 150, the length of the second gas passage 160 is shortened, the position layout of each passage inside the wok burning valve body 110 is more compact, so that the size of the wok burning valve body 110 can be designed to be smaller, and the space occupied by the wok burning valve 100 is further reduced.

[0065] In other alternative embodiments, the valve port 170 can also be arranged between the first gas passage 150 and the wok burning inlet passage 130, in which case, one end of the second gas passage 160 is in communication with the first gas passage 150, the other end of the second gas passage 160 is in communication with the wok burning inlet passage 130, and the second gas passage 160 is in communication with the wok burning outlet passage 140 through the first gas passage 150.

[0066] Further, as shown in FIG. 2, the wok burning valve 100 further comprises a wok burning valve body 110 and a wok burning valve core 120. Figure 3As shown, the second gas passage 160 penetrates to the valve port 170. The second gas passage 160 directly penetrates the valve port 170, so that when the wok burning valve 100 is in the wok burning state, the valve port 170 and the port of the second gas passage 160 jointly form an opening with a larger size for the gas flow, reducing the resistance to the gas flow, making the gas flow more smooth, and improving the wok burning effect of the wok burning valve 100.

[0067] In other embodiments, the second gas passage 160 can also be independently arranged relative to the valve port 170, as long as it does not affect the normal passage of gas through the second gas passage 160.

[0068] In this embodiment, the projection of the valve port 170 on the wok burning valve core 120 along the moving direction of the wok burning valve core 120 partially overlaps the wok burning valve core 120, and the part of the projection of the valve port 170 on the wok burning valve core 120 along the moving direction of the wok burning valve core 120 that does not overlap the wok burning valve core 120 forms the second gas passage 160. The wok burning valve core 120 cannot completely block the valve port 170, and the part that is not blocked forms the second gas passage 160. When the wok burning valve 100 is in the normal state, the wok burning valve core 120 blocks part of the valve port 170 area, and the gas passes through the valve port 170 area that is not blocked by the wok burning valve core 120 and enters the wok burning gas outlet passage 140.

[0069] Specifically, as shown, Figure 3 The wok burning valve core 120 is arc-shaped, and the peripheral side surface of the wok burning valve core 120 includes a flat surface and an arc surface. The flat surface and the inner side wall of the corresponding side of the valve port 170 form a gap in the radial direction of the valve port 170, and the gap forms the second gas passage 160. The wok burning valve core 120 has an end surface opposite to the valve port 170, and the maximum diameter of the end surface is larger than the diameter of the valve port 170. A semicircular notch 121 is arranged on the end surface, and the second gas passage 160 is formed at the notch 121 when the end surface abuts against the valve port 170. The wok burning valve core 120 is arc-shaped and can be directly cut from a traditional circular valve core, which is simple in structure and convenient to process. The maximum diameter is unchanged, which will not cause the second gas passage 160 to become larger or smaller, nor will it affect the cooperation between the wok burning valve core 120 and the valve port 170. The maximum diameter of the end surface of the wok burning valve core 120 is larger than the diameter of the valve port 170, which avoids the wok burning valve core 120 from falling off the valve port 170 and affecting the opening and closing of the wok burning valve 100. When the wok burning valve 100 is in the normal state, the gas only passes through the second gas passage 160 formed at the notch 121. In other embodiments, the wok burning valve core 120 can also be arranged in other structures, for example, a through hole is arranged directly on the end surface of the wok burning valve core 120, as long as the second gas passage 160 is always connected to the wok burning gas inlet passage 130 and the wok burning gas outlet passage 140.

[0070] In the embodiment, the material of the searing spool 120 is rubber. The use of the rubber material for the searing spool 120 makes the sealing between the searing spool 120 and the valve port 170 good, and the hardness of the rubber material is low, which does not easily damage the valve port 170 and the inner wall of the first gas passage 150 in the moving process, and affects the sealing. At the same time, the corrosion resistance and the anti-aging ability of the rubber material are strong, which can effectively withstand the gas and high temperature environment, and prolong the service life of the searing spool 120. In other embodiments, the searing spool 120 can use other materials, as long as it does not affect the cooperation between the valve port 170 and the searing spool 120.

[0071] Further, as shown in Figure 1 , the searing valve 100 and the plug valve 200 are arranged side by side at the edge of the stove away from the ejector pipe 300, which effectively avoids the influence of the high temperature generated by the ejector pipe 300 on the searing valve 100 during operation, thereby shortening the service life of the searing valve 100.

[0072] In other alternative embodiments, the searing valve 100 described above can also be connected between the outer ring gas outlet passage 220 and the outer ring ejector pipe 320 of the plug valve 200 to realize the outer ring searing function. In this case, the searing inlet passage 130 of the searing valve 100 is connected with the outer ring gas outlet passage 220 of the plug valve 200, the searing outlet passage 140 of the searing valve 100 is connected with the outer ring ejector pipe 320, and the inner ring gas outlet passage 210 of the plug valve 200 is directly connected with the inner ring ejector pipe 310.

[0073] Embodiment 2

[0074] The stove and the searing valve 100 in the embodiment are basically the same as those in Embodiment 1, and the difference lies in the structure of the second gas passage 160.

[0075] In the embodiment, as shown in Figure 6 , the searing valve body 110 includes a ring-shaped protruding portion 180, the protruding portion 180 extends from the inner side wall of the first gas passage 150 to the inside of the first gas passage 150, and the port at the end of the protruding portion 180 away from the inner side wall of the first gas passage 150 forms the valve port 170. The second gas passage 160 is arranged on the peripheral side wall of the protruding portion 180, and the two ends of the second gas passage 160 penetrate through the peripheral side wall of the protruding portion 180. In the embodiment, the protruding portion 180 is arranged at the searing valve body 110, which shortens the moving stroke of the searing spool 120. The second gas passage 160 is directly formed on the peripheral side wall of the protruding portion 180, without the need to improve the structure of the searing spool 120. In other embodiments, other structures can be arranged at the valve port 170 to make the second gas passage 160 communicate, while controlling the gas supply amount of the second gas passage 160, as long as it does not affect the valve port 170 and the searing spool 120.

[0076] The upper end of the second gas passage 160 penetrates to the upper end surface of the protruding part 180, so that when the stir-frying valve 100 is in the stir-frying state, the second gas passage 160 communicates with the valve port 170 to form an opening with a larger size for the gas flow.

[0077] Specifically, along the extension direction of the protruding part 180, the protruding part 180 comprises a first protruding unit 181 and a second protruding unit 182, the first protruding unit 181 is connected with the inner side wall of the first gas passage 150, and the second protruding unit 182 is arranged at one end of the first protruding unit 181 towards the stir-frying valve core 120; the second gas passage 160 is arranged on the circumferential side wall of the second protruding unit 182, and the wall thickness of the circumferential side wall of the second protruding unit 182 is smaller than the wall thickness of the circumferential side wall of the first protruding unit 181. The wall thickness of the second protruding unit 182 is smaller than the first protruding unit 181, so as to shorten the length of the second gas passage 160 and make the resistance smaller when the gas passes through the second gas passage 160.

[0078] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, the protection scope of the present application is defined by the appended claims.
