The gas stove includes a combustion system, which is the core part of the gas stove. Its main function is to mix and ignite gas and air to generate a flame for cooking.

[0003] The combustion system of the related technology includes a cock valve assembly, an ejector pipe, a burner, and an ignition device. One end of the ejector pipe is communicated with the cock valve assembly, and the other end is communicated with the burner. Gas is transported from the gas supply source into the cock valve assembly and enters the burner along the ejector pipe. The ignition device is used to ignite the gas, so that the burner can generate a flame; in order to enable the gas stove to have a stir-fry function, a delivery pipe is also provided between the cock valve assembly and the burner, so that the delivery pipe can transport the gas required in the stir-fry state, so that the burner generates a larger flame to achieve the stir-fry function.

[0004] However, with the setting of the delivery pipe, one end of the delivery pipe needs to be communicated with the cock valve assembly, and the other end of the delivery pipe needs to be communicated with the burner, which results in the delivery pipe occupying the internal space of the gas stove. Summary of the Invention

[0005] The present application provides a combustion system and a cooking device to solve the technical problem that the delivery pipe for realizing the stir-fry function in the gas stove of the related technology occupies the internal space of the gas stove.

[0008] A gas ejector pipe and a burner, both the gas ejector pipe and the burner are used to be arranged on the gas stove. One end of the gas ejector pipe is communicated with the gas outlet, and the other end of the gas ejector pipe is communicated with the burner;

[0009] An adjusting device arranged on the gas ejector pipe, the adjusting device is used to increase the gas outlet volume in the gas ejector pipe when the burner is in the stir-fry state; and decrease the gas outlet volume in the gas ejector pipe when the burner is in the normal state.

[0010] In some embodiments, the adjusting device includes an electronically controlled valve, which includes a valve body, a valve core, and a driving assembly. The valve body has an air inlet and an air outlet, and a valve body channel is formed between the air inlet and the air outlet. The electronically controlled valve is connected in series to the gas ejector pipe through the air inlet and the air outlet. The valve core is arranged in the valve body, and the driving assembly is used to drive the valve core to move relative to the valve body to increase or decrease the gas outlet volume entering the gas ejector pipe through the air outlet.

[0011] In some embodiments, the valve core has a valve core channel, and the minimum flow area of the valve core channel is smaller than the minimum flow area of the valve body channel. The driving assembly is used to drive the valve core to move relative to the valve body so that the valve core channel replaces part of the valve body channel to increase or decrease the minimum flow area of the valve body channel, thereby increasing or decreasing the gas outlet volume.

[0012] In some embodiments, the valve core has an air inlet hole, a first air hole, and a second air hole. A first valve core channel is formed between the air inlet hole and the first air hole, and a second valve core channel is formed between the air inlet hole and the second air hole. The minimum flow areas of the first valve core channel and the second valve core channel are not equal. The driving assembly drives the valve core to move in the valve body channel so that the first valve core channel and the second valve core channel alternately replace part of the valve body channel.

[0013] In some embodiments, the first valve core channel and the second valve core channel are distributed along the circumferential direction of the valve core, and the driving assembly drives the valve core to rotate in the valve body so that the first valve core channel and the second valve core channel alternately replace part of the valve body channel.

[0014] In some embodiments, the valve body is provided with a receiving groove for receiving the valve core. The receiving groove is communicated with the valve body channel. The driving assembly drives the valve core to move between the valve body channel and the receiving groove. When the valve core is located in the valve body channel, the valve core channel replaces part of the valve body channel. When the valve core is located in the receiving groove, the valve core channel no longer replaces part of the valve body channel.

[0015] In some embodiments, the valve body channel includes a first valve body channel and a second valve body channel. When the valve core is located in the valve body channel, the gas flows through the first valve body channel, the valve core channel, and the second valve body channel in sequence. The included angle between the moving direction of the valve core from the valve body channel to the receiving groove and the gas flow direction in the first valve body channel is α, where 0 ≤ α ≤ 30°.

When the burner is in the normal state, the adjusting device can reduce the gas outlet volume of the gas in the gas injection pipe, making the burner suitable for the user's normal state demand; by arranging the adjusting device on the gas injection pipe, there is no need for an additional larger-diameter pipeline to transport more gas to the burner, reducing the number of pipelines for transporting gas, thereby reducing the space occupied by the combustion system, and thus reducing the space occupied inside the gas stove; by using the adjusting device to increase or decrease the gas outlet volume of the gas in the gas injection pipe, the adjusting device drives the gas stove to achieve both the normal state and the stir-fry state simultaneously, indirectly improving the applicability of the gas stove; by arranging the adjusting device on the gas injection pipe and separating it from the cock valve assembly, when the cock valve assembly or the adjusting device is damaged and needs to be replaced, only the cock valve assembly or the adjusting device needs to be replaced separately, reducing the maintenance and replacement cost.

[0049] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of Specific Embodiments

[0050] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] As described in the background art, the combustion system of the related art includes a cock valve assembly, an ejector tube, a burner, and an ignition device. One end of the ejector tube is communicated with the cock valve assembly, and the other end is communicated with the burner. Gas is transported from the gas supply source into the cock valve assembly and enters the burner along the ejector tube. The ignition device is used to ignite the gas so that the burner can generate a flame. In order to enable the gas stove to have a stir-fry function, a delivery pipe is further provided between the cock valve assembly and the burner so that the delivery pipe can deliver the gas required during stir-frying, thereby enabling the burner to generate a larger flame for realizing the stir-fry function.

[0052] However, with the arrangement of the delivery pipe, one end of the delivery pipe needs to be connected to the cock valve assembly, and the other end of the delivery pipe needs to be connected to the burner, resulting in the delivery pipe occupying a relatively large layout space. Moreover, the diameter of the delivery pipe for delivering gas during high-fire stir-frying is relatively large, further causing the delivery pipe to occupy a relatively large layout space.

[0053] To address the above technical problems, the embodiments of the present application provide a combustion system and a cooking device. When the cock valve assembly controls the burner to be in the high-fire stir-frying state, at this time, the driving component drives the valve core to rotate within the valve body, causing the valve core to drive the first air hole to communicate with the air outlet. Since the diameter of the air outlet is greater than or equal to the diameter of the first air hole, and the diameter of the first air hole is greater than the diameter of the second air hole, when the gas in the gas injection pipe passes through the first air hole, the gas outlet volume of the gas can be increased, so that the gas outlet volume of the gas adapts to the burner in the high-fire stir-frying state. When the cock valve assembly controls the burner to be in the high-fire stir-frying state, at this time, the driving component drives the valve core to move within the valve body, causing the valve core to drive the third air hole to be disconnected from the air outlet. At this time, the valve core can move away from the air outlet, thus preventing the valve core from affecting the gas outlet of the air outlet. Since the diameter of the air outlet is greater than the diameter of the third air hole, the gas directly enters from the air inlet and is discharged from the air outlet, thereby increasing the gas outlet volume of the gas, so that the gas outlet volume of the gas adapts to the burner in the high-fire stir-frying state. By controlling the gas outlet volume of the gas in the valve body on the gas injection pipe through the valve core, the gas injection pipe can enable the burner to be applicable to both the normal state and the high-fire stir-frying state, thus eliminating the need for an additional larger-diameter pipeline to deliver more gas to the burner, reducing the number of pipelines for delivering gas, and thereby reducing the space occupied by the combustion system.

[0054] The following uses specific embodiments to elaborate in detail on the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application in conjunction with the drawings.

[0055] As Figure 1 shown, a combustion system includes:

[0056] A cock valve assembly 100, the cock valve assembly 100 has a gas outlet 110, and the cock valve assembly 100 is used to be arranged on a gas stove 700 and is used to communicate with the gas supply source of the gas stove 700;

[0057] A gas injection pipe 200 and a burner 300, both the gas injection pipe 200 and the burner 300 are used to be arranged on the gas stove 700. One end of the gas injection pipe 200 is connected to the gas outlet 110, and the other end of the gas injection pipe 200 is connected to the burner 300;

[0058] The regulating device 400 is arranged on the gas ejector pipe 200. The regulating device 400 is used to increase the gas outlet volume in the gas ejector pipe 200 when the burner 300 is in the stir-fry state; and decrease the gas outlet volume in the gas ejector pipe 200 when the burner 300 is in the normal state.

[0059] In this application, the regulating device 400 can increase the gas outlet volume in the gas ejector pipe 200 when the burner 300 is in the stir-fry state, thereby increasing the firepower of the burner 300, enabling the burner 300 to adapt to the situation where users have a stir-fry demand. When the burner 300 is in the normal state, the regulating device 400 decreases the gas outlet volume in the gas ejector pipe 200, enabling the burner 300 to meet the needs of users in the normal state. By arranging the regulating device 400 on the gas ejector pipe 200, there is no need for an additional larger-diameter pipeline to transport more gas to the burner 300, reducing the number of pipelines for transporting gas, thereby reducing the space occupied by the combustion system and thus reducing the space occupied inside the gas stove 700. By using the regulating device 400 to increase or decrease the gas outlet volume in the gas ejector pipe 200, the regulating device 400 drives the gas stove 700 to achieve both the normal state and the stir-fry state simultaneously, indirectly improving the applicability of the gas stove 700. By arranging the regulating device 400 on the gas ejector pipe 200 and separating it from the cock valve assembly 100, when the cock valve assembly 100 or the regulating device 400 is damaged and needs to be replaced, only the cock valve assembly 100 or the regulating device 400 needs to be replaced separately, reducing the cost of maintenance and replacement. And when the regulating device 400 is damaged, the cock valve assembly 100 can still continue to work normally, thus ensuring the normal use of the gas stove 700. The cock valve assembly 100 and the regulating device 400 can be produced separately, reducing the complexity and cost in the production process of the cock valve assembly 100 and the regulating device 400.

[0060] Combined Figure 2 and Figure 3 , the burner 300 includes:

[0061] The stove top 310;

[0062] The central burner cap 322 is arranged on the stove top 310. The central burner cap 322 is used to form an inner ring flame. The regulating device 400 is arranged on the gas ejector pipe 200 communicated with the central burner cap 322.

[0063] In this embodiment, the burner 300 further includes an outer ring burner cap 332. The outer ring burner cap 332 is arranged on the stove top 310. The outer ring burner cap 332 is used to form an outer ring flame.

[0064] Inside the central burner cap 322, there is a middle ring channel 320. Inside the outer ring burner cap 332, there is an outer ring channel 330. The gas outlet 110 includes a main outlet 111 and a secondary outlet 112. The gas injection pipe 200 includes a main injection pipe 210 and a secondary injection pipe 220. One end of the main injection pipe 210 is connected to the main outlet 111, and the other end of the main injection pipe 210 is connected to the outer ring channel 330. One end of the secondary injection pipe 220 is connected to the secondary outlet 112, and the other end of the secondary injection pipe 220 is connected to the middle ring channel 320. The adjusting device 400 is arranged on the secondary injection pipe 220.

[0065] In this embodiment, there are two burners 300, and the gas stove 700 with two burners 300 is a double-eye stove or a double-burner stove. There is a middle ring boss 321 on the stove top 310 and at the central position of the stove top 310. The middle ring boss 321 is integrally annular, and the cross-section of the middle ring boss 321 is set as a "U" shape. The central burner cap 322 is snap-fitted on the "U"-shaped middle ring boss 321. The central burner cap 322 is integrally annular, and the cross-section of the central burner cap 322 is set as an inverted "U" shape. A middle ring channel 320 is formed between the central burner cap 322 and the middle ring boss 321. A plurality of first fire holes 323 are arranged on the outer side of the central burner cap 322 along the circumferential direction of the central burner cap 322. There is an outer ring boss 331 on the stove top 310 along the circumferential edge of the stove top 310. The outer ring boss 331 is integrally annular, and the cross-section of the outer ring boss 331 is set as a "U" shape. The outer ring burner cap 332 is snap-fitted on the "U"-shaped outer ring boss 331. The outer ring burner cap 332 is integrally annular, and the cross-section of the outer ring burner cap 332 is set as an inverted "U" shape. An outer ring channel 330 is formed between the outer ring burner cap 332 and the outer ring boss 331. Second fire holes 333 are arranged on the outer side of the outer ring burner cap 332 and around the inner side of the outer ring burner cap 332.

[0066] In this embodiment, the adjusting device 400 is arranged on the secondary injection pipe 220. Since the flame in the middle ring channel 320 is the main heating source, the stir-fry function of the burner 300 can be satisfied by controlling the firepower of the middle ring channel 320. In other embodiments, the adjusting device 400 can be arranged on both the main injection pipe 210 and the secondary injection pipe 220 at the same time, or the adjusting device 400 can be arranged on the secondary injection pipe 220.

[0067] In this application, by adopting the settings of the middle ring channel 320, the outer ring channel 330, the main injection pipe 210, and the secondary injection pipe 220, gas can be transported to the main injection pipe 210 and the secondary injection pipe 220 through the main outlet 111 and the secondary outlet 112, and transported to the outer ring channel 330 and the middle ring channel 320 along the main injection pipe 210 and the secondary injection pipe 220, so that flames can be ignited in both the middle ring channel 320 and the outer ring channel 330 for cooking, indirectly improving the heating efficiency of the burner 300.

[0068] Combined with Figure 2 and Figure 3 In this embodiment, an ignition device 311 is provided on the stove top 310. The ignition device 311 is set as an igniter, which ignites the gas by generating an electric spark, thereby realizing the ignition function of the gas stove 700. A thermocouple 312 is provided on the stove head 310 and on one side relative to the ignition device 311. The main function of the thermocouple 312 in the gas stove 700 is as a flameout protection device, and the thermocouple 312 can sense the temperature of the flame. When the gas stove 700 is burning normally, the flame heats the thermocouple 312, causing it to generate a thermoelectric potential, and the generated thermoelectric potential is used to maintain the suction state of the solenoid valve and keep the gas supply continuous. In this way, even if the cock valve assembly 100 is not pressed by the user, the gas stove 700 can continue to burn. If the gas stove 700 accidentally goes out, the thermocouple 312 will cool down rapidly, and the thermoelectric potential will drop to zero, which will cause the solenoid valve to lose power and quickly reset under the action of the spring, cutting off the gas supply to prevent gas leakage and thus protecting the safety of the user. The thermocouple 312 is a prior art, and its specific structure will not be described in detail here.

[0069] Combined with Figure 1 、 Figure 4 and Figure 5 The adjusting device 400 includes an electromagnetic control valve 410. The electromagnetic control valve 410 includes a valve body 420, a valve core 430 and a driving component 440. The valve body 420 has an air inlet 421 and an air outlet 422. A valve body passage 425 is formed between the air inlet 421 and the air outlet 422. The electromagnetic control valve 410 is connected in series to the gas injection pipe 200 through the air inlet 421 and the air outlet 422. The valve core 430 is arranged inside the valve body 420, and the driving component 440 is used to drive the valve core 430 to move relative to the valve body 420 to increase or decrease the gas outlet volume entering the gas injection pipe 200 through the air outlet 422.

[0070] In this embodiment, the diameter of the air inlet 421 is the same as that of the air outlet 422, and the air inlet 421 and the air outlet 422 are arranged perpendicular to each other. The electromagnetic control valve 410 is connected in series to the secondary injection pipe 220 through the air inlet 421 and the air outlet 422. In other embodiments, the diameter of the air inlet 421 can also be larger than that of the air outlet 422.

[0071] In this application, by adopting the setting of the electric control valve 410, the driving assembly 440 can drive the valve core 430 to move within the valve body 420, so that the valve core 430 increases or decreases the gas outlet volume entering the secondary ejector tube 220 through the air outlet 422. Thus, it is convenient to adjust the gas outlet volume when the burner 300 is in the high-fire stir-fry state. By adopting the settings of the valve body 420, the valve core 430 and the driving assembly 440, the structure is simple, the simplicity of the electric control valve 410 for adjusting the gas outlet volume is improved, and the space occupied by the electric control valve 410 is reduced, thereby indirectly reducing the space occupied by the combustion system; by connecting the electric control valve 410 in series on the secondary ejector tube 220 through the air inlet 421 and the air outlet 422, the gas in the secondary ejector tube 220 can enter through the air inlet 421 and be discharged along the air outlet 422 back into the secondary ejector tube 220, so that it is convenient to change the gas passing through the valve core 430 to adjust the outlet volume entering the secondary ejector tube 220.

[0072] The valve core 430 has a valve core passage 434, and the minimum flow area of the valve core passage 434 is smaller than the minimum flow area of the valve body passage 425. The driving assembly 440 is used to drive the valve core 430 to move relative to the valve body 420, so that the valve core passage 434 replaces part of the valve body passage 425 to increase or decrease the minimum flow area of the valve body passage 425, thereby increasing or decreasing the gas outlet volume.

[0073] Combined Figure 4 and Figure 5 , the valve core 430 has an air inlet hole 435, a first air hole 431 and a second air hole 432. A first valve core passage 436 is formed between the air inlet hole 435 and the first air hole 431, and a second valve core passage 437 is formed between the air inlet hole 435 and the second air hole 432. The minimum flow areas of the first valve core passage 436 and the second valve core passage 437 are not equal. The driving assembly 440 drives the valve core 430 to move within the valve body passage 425, so that the first valve core passage 436 and the second valve core passage 437 alternately replace part of the valve body passage 425..

[0074] In this embodiment, when at least part of the first air hole 431 is in communication with the air outlet 422, the first valve core passage 436 between the air inlet hole 435 and the first air hole 431 can replace part of the valve body passage 425 between the air inlet 421 and the air outlet 422; when at least part of the second air hole 432 is in communication with the air outlet 422, the second valve core passage 437 between the air inlet hole 435 and the second air hole 431 can replace part of the valve body passage 425 between the air inlet 421 and the air outlet 422.

[0075] In this embodiment, the diameter of the air inlet hole 435 is greater than, equal to, or less than the diameter of the air inlet 421, the diameter of the air outlet 422 is greater than or equal to the diameter of the first air hole 431, and the diameter of the first air hole 431 is greater than the diameter of the second air hole 432; in other embodiments, the diameters of the first air hole 431, the air outlet 422, and the second air hole 432 can be decreased in sequence, or the diameters of the first air hole 431, the air outlet 422, and the second air hole 432 can be increased in sequence, and the diameters of the first air hole 431, the air outlet 422, and the second air hole 432 can be adaptively adjusted as needed.

[0076] In this application, when the cock valve assembly 100 controls the burner 300 to be in the normal state, at this time, the driving component 440 drives the valve core 430 to move in the valve body 420, so that the valve core 430 drives the second air hole 432 to communicate with the air outlet 422. Since the diameter of the second air hole 432 is smaller than the diameter of the first air hole 431 and the diameter of the second air hole 432 is smaller than the diameter of the air outlet 422, when the gas in the secondary ejector tube 220 passes through the second air hole 432, the gas outlet volume of the gas can be reduced, so that the gas outlet volume of the gas adapts to the burner 300 in the normal state; when the driving component 440 drives the second air hole 432 to stagger with the air outlet 422, the second air hole 432 and the air outlet 422 are partially communicated, and the gas outlet volume of the gas can be controlled when the burner 300 is in the normal state, so that when the burner 300 is in the normal state, the flame size of the burner 300 can be controlled. By controlling the flames of different sizes of the burner 300, it is convenient to adapt to different firepower requirements of users.

[0077] When the cock valve assembly 100 controls the burner 300 to be in the stir-fry state, at this time, the driving component 440 drives the valve core 430 to move in the valve body 420, so that the valve core 430 drives the first air hole 431 to communicate with the air outlet 422. Since the diameter of the air outlet 422 is greater than or equal to the diameter of the first air hole 431 and the diameter of the first air hole 431 is greater than the diameter of the second air hole 432, when the gas in the secondary ejector tube 220 passes through the first air hole 431, the gas outlet volume of the gas can be increased, so that the gas outlet volume of the gas adapts to the burner 300 in the stir-fry state; when the driving component 440 drives the first air hole 431 to stagger with the air outlet 422, the first air hole 431 and the air outlet 422 are partially communicated, and the flame size of the burner 300 can be controlled when the burner 300 is in the stir-fry state. By controlling the flames of different sizes of the burner 300, it is convenient to further adapt to different firepower requirements of users, thereby further improving the heating efficiency of the burner 300.

[0078] Combined Figure 4 and Figure 5, the first spool passage 436 and the second spool passage 437 are circumferentially distributed along the spool, and the driving assembly 440 drives the spool 430 to rotate within the valve body 420 such that the first spool passage 436 and the second spool passage 437 alternately replace part of the valve body passage 425.

[0079] Combined Figure 4 and Figure 5 , the driving assembly 440 includes a rotary motor.

[0080] In this embodiment, the electric control valve 410 further includes a motor seat 450. The motor seat 450 is detachably connected to the end of the valve body 420 away from the air inlet 421 by screws, and the rotary motor is fixed to the valve body 420 through the motor seat 450; the electric control valve 410 further includes a connecting member 460 and a transmission shaft 470. The connecting member 460 is sleeved on the motor shaft of the rotary motor, the transmission shaft 470 is inserted into the connecting member 460, the transmission shaft 470 passes through the motor seat 450, and the end of the transmission shaft 470 away from the rotary motor is inserted into the central groove of the spool 430, so that the motor shaft of the rotary motor drives the spool 430 to rotate; the electric control valve 410 further includes a sensor circuit 480 and a magnet member. The sensor circuit 480 can detect the position of the magnet member, thereby knowing the rotation position of the spool 430, so as to facilitate identifying whether the burner 300 is in a normal state or a stir-fry state.

[0081] In this application, the spool 430 is driven to rotate by a rotary motor, so that the spool 430 can drive at least part of the first air hole 431 or the second air hole 432 to communicate with the air outlet 422. With the arrangement of the rotary motor, the structure is simple, thereby preventing deviation between the first air hole 431 and the second air hole 432 and the air outlet 422, and thus improving the accuracy when the spool 430 rotates within the valve body 420.

[0082] Combined Figures 9 to 11 , in some embodiments, the valve body 420 is provided with a receiving groove 423 for receiving the spool 430. The receiving groove 423 communicates with the valve body passage 425. The driving assembly 440 drives the spool 430 to move between the valve body passage 425 and the receiving groove 423. When the spool 430 is located within the valve body passage 425, the spool passage 434 replaces part of the valve body passage 425. When the spool 430 is located within the receiving groove 423, the spool passage 434 no longer replaces part of the valve body passage 425.

[0083] The valve body passage 425 includes a first valve body passage 426 and a second valve body passage 427. When the spool 430 is located within the valve body passage 425, the gas flows through the first valve body passage 426, the spool passage 434, and the second valve body passage 427 in sequence. The included angle between the moving direction of the spool 430 from the valve body passage 425 to the receiving groove 423 and the gas flow direction in the first valve body passage 426 is α, and 0 ≤ α ≤ 30°.

[0084] In this embodiment, the valve core 430 has a third air outlet hole 433. Between the air inlet hole 435 and the third air outlet hole 433 is a valve core channel 423. A first valve body channel 426 is formed between the air inlet hole 435 and the air inlet 421, and a second valve body channel 427 is formed between the third air outlet hole 433 and the air outlet 422. The driving assembly 440 is used to drive the valve core 430 to axially move within the valve body 420, so as to drive at least part of the third air outlet hole 433 to communicate with the air outlet 422, thereby increasing or decreasing the minimum flow area of the valve body channel 425. In this embodiment, α is 0°.

[0085] In this embodiment, when at least part of the third air outlet hole 433 communicates with the air outlet 422, the first valve body channel 426 formed between the air inlet 421 and the third air outlet hole 433 and the second valve body channel 427 formed between the third air outlet hole 433 and the air outlet 422 replace part of the valve body channel 425 between the air inlet 421 and the air outlet 422; when the third air outlet hole 433 is disengaged from the air outlet 422, at this time the valve core 430 moves into the receiving groove 423, and the third air outlet hole 433 does not replace the valve body channel 425, and the gas is directly output through the valve body channel 425 between the air inlet 421 and the air outlet 422.

[0086] The diameter of the air outlet 422 is larger than the diameter of the third air outlet hole 433; in other embodiments, the diameter of the air outlet 422 can also be smaller than or equal to the diameter of the third air outlet hole 433, so that when the third air outlet hole 433 and the air outlet 422 are staggered, the minimum flow area of the valve body channel 425 is increased or decreased, thereby increasing or decreasing the gas outlet volume.

[0087] In this application, when the cock valve assembly 100 controls the burner 300 to be in a normal state, at this time the driving assembly 440 drives the valve core 430 to move within the valve body 420, so that the valve core 430 drives the third air outlet hole 433 to communicate with the air outlet 422. Since the diameter of the air outlet 422 is larger than the diameter of the third air outlet hole 433, when the gas in the secondary ejector tube 220 passes through the third air outlet hole 433, the gas outlet volume can be reduced, so that the gas outlet volume adapts to the burner 300 in the normal state; when the driving assembly 440 drives the third air outlet hole 433 and the air outlet 422 to be staggered, so that the third air outlet hole 433 and the air outlet 422 are partially communicated, the gas outlet volume can be controlled when the burner 300 is in the normal state, so that when the burner 300 is in the normal state, the flame size of the burner 300 can be controlled. By controlling different sizes of flames of the burner 300, it is convenient to adapt to different firepower requirements of users.

[0088] When the cock valve assembly 100 controls the burner 300 to be in the stir-fry state, at this time, the driving component 440 drives the valve core 430 to move in the valve body 420, so that the valve core 430 drives the valve core 430 to be disengaged from the air outlet 422. At this time, the valve core 430 moves into the receiving groove, thereby preventing the valve core 430 from affecting the air outlet of the air outlet 422. Since the diameter of the air outlet 422 is larger than the diameter of the third air outlet hole 433, the gas directly enters from the air inlet 421 and is discharged from the air outlet 422, thereby increasing the gas outlet volume, so that the gas outlet volume adapts to the burner 300 in the stir-fry state; when the driving component 440 drives the third air outlet hole 433 to be staggered with the air outlet 422, the third air outlet hole 433 is partially communicated with the air outlet 422, and the flame size of the burner 300 can be controlled when the burner 300 is in the stir-fry state. By controlling the different sizes of the flame of the burner 300, it is convenient to further adapt to the different firepower requirements of users, thereby further improving the heating efficiency of the burner 300.

[0089] Combined with Figures 9 to 11 , the driving component 440 includes a push rod motor.

[0090] In this embodiment, the push rod motor is connected to the valve body 420 by bolts; when the valve core 430 is located in the receiving groove 423, the valve core 430 can be far away from the air outlet 422, thereby preventing the valve core 430 from affecting the delivery of gas from the air inlet 421 to the air outlet 422; a sealing ring 424 is arranged between the valve core 430 and the inner wall of the receiving groove 423, and the sealing ring 424 can prevent the gas from leaking along the gap between the valve core 430 and the inner wall of the receiving groove 423.

[0091] In this application, by using a push rod motor to drive the valve core 430 to move axially along the valve body 420 in the valve body 420, the valve core 430 can be close to or far away from the air outlet 422. With the arrangement of the push rod motor, the structure is simple and the driving effect on the valve core 430 is improved.

[0092] Combined with Figure 3 and Figure 6 , the combustion system further includes an air supply device 500. The air supply device 500 is arranged on the furnace table 310, and the air supply device 500 is used to increase or decrease the air supply volume of the central burner cap 322.

[0093] By adopting the air supply device 500, increasing the air supply during the stir-frying state can ensure the full mixing of gas and air, thus achieving complete combustion, improving the thermal efficiency, and saving gas; by adjusting the air supply volume, the size and intensity of the flame of the burner 300 can be controlled to meet different cooking requirements; when in the stir-frying state, due to the increase in the gas outlet volume, by increasing the air supply volume, the gas can be completely burned, thereby reducing the products of incomplete combustion, such as the emission of harmful gases like carbon monoxide, and improving the safety of the kitchen; and the complete combustion of gas can reduce the carbon deposition on the stove top 310 and the burner 300, keep the cooker clean, and extend the service life; and by adopting appropriate oxygen supply, the food can be heated evenly during cooking, avoiding local overheating or burning, and improving the cooking effect; by adjusting the air supply volume, the risk of incomplete combustion is reduced, the possibility of gas leakage is lowered, and the overall safety of the gas stove 700 is indirectly improved.

[0094] Combined with Figure 3 and Figure 6 , the air supply device 500 includes a cap 520 and a moving component 530. The cap 520 is connected to the moving component 530. The moving component 530 is used to drive the cap 520 to approach or move away from the central burner cap 322, so as to close or open the central through-hole 313 of the central burner cap 322, thereby reducing or increasing the air supply volume of the central burner cap 322.

[0095] In this embodiment, the moving component 530 is a driving motor. The air supply device 500 further includes a connecting rod 510; the connecting rod 510 is inserted into the central through-hole 313. The diameter of the connecting rod 510 is smaller than the diameter of the central through-hole 313. The cap 520 is arranged at one end of the connecting rod 510. The other end of the connecting rod 510 is connected to the driving end of the driving motor. The driving motor is used to be arranged on the gas stove 700. The driving motor is used to drive the connecting rod 510 to move up and down, so that the connecting rod 510 drives the cap 520 to abut against or disengage from the central burner cap 322; when the burner 300 is in the stir-frying state, the driving motor drives the connecting rod 510 to rise, so that the connecting rod 510 drives the cap 520 to move away from the central burner cap 322 to open the central through-hole 313, thereby increasing the air supply volume; when the burner 300 is in the normal state, the driving motor drives the connecting rod 510 to descend, so that the connecting rod 510 drives the cap 520 to abut against the central burner cap 322 to close the central through-hole 313, thereby reducing the air supply volume, thus preventing too much air from carrying the heat of the burner 300 and preventing the influence on the energy efficiency of the burner 300.

[0096] In other embodiments, the air supply device can be a compressed air tank. By connecting the air outlet end of the compressed air tank to the central through-hole 313, the burner can also be supplemented with air when the compressed air tank is opened.

[0097] As Figure 12 shown, in some embodiments, the air supply device 500 includes a cover 540 and a blower 550. The cover 540 is disposed at the end of the central through hole 313. A ventilation hole 541 communicating with the central through hole 313 is provided on the cover 540. The blower 550 is configured to blow air through the central through hole 313 to the ventilation hole 541.

[0098] When the burner 300 is in the stir-fry state, the blower 550 blows air through the central through hole to the ventilation hole 541, so that the ventilation hole 541 blows air toward the central burner cap 322, thereby increasing the air supply; when the burner 300 is in the normal state, the blower 550 stops blowing air through the central through hole 313 to the ventilation hole 541, thereby reducing the air supply, thereby preventing excessive air from taking away the heat of the burner 300, thereby preventing the influence on the energy efficiency of the burner 300.

[0099] Combined with Figure 1 、 Figure 7 and Figure 8 , the combustion system further includes a stir-fry key 600. The stir-fry key 600 is configured to be arranged on the gas stove 700 and is used to open and close the regulating device 400.

[0100] In this embodiment, the combustion system further includes a keypad 610. The keypad 610 is configured to be arranged on the gas stove 700, and the stir-fry key 600 is arranged on the keypad 610; other function keys such as an on / off key or a display screen of the gas stove 700 are also arranged on the keypad 610.

[0101] In this embodiment, the cock valve assembly 100 includes a valve rod 120, an ignition switch 130, and a maximum position switch 140. Both the ignition switch 130 and the maximum position switch 140 are set as microswitches. The valve rod 120 can be pressed down or bounced up to turn on or off the ignition switch 130. When the ignition switch 130 is turned on, the ignition switch 130 can start the ignition device 311 through a control board, so that the ignition device 311 ignites the burner 300. After the valve rod 120 is pressed down, it can rotate to switch between a normal position and a stir-fry position. When the valve rod 120 is in the normal position, the control board can drive the driving component 440 through the control board to connect the second air hole 432 with the air outlet 422. By driving the valve rod 120 to rotate, the valve rod 120 is rotated in a direction away from the stir-fry position, so as to adjust the staggered state of the second air hole 432 and the air outlet 422, so that the second air hole 432 is partially communicated with the air outlet 422, thereby adjusting the size of the flame of the burner 300 in the normal state. When the valve rod 120 rotates to face the stir-fry position, the valve rod 120 can turn on the maximum position switch 140. At the same time, the thermocouple 312 detects whether the burner 300 is in a working state with a flame. When the user presses the stir-fry key 600, the control board drives the driving component 440 to connect the first air hole 431 with the air outlet 422, so that the burner 300 is in the stir-fry state. By driving the valve rod 120 to rotate, the valve rod 120 is rotated towards the normal position, so as to adjust the staggered state of the first air hole 431 and the air outlet 422, so that the first air hole 431 is partially communicated with the air outlet 422, thereby adjusting the size of the flame of the burner 300 in the stir-fry state. The cock valve assembly 100 belongs to the prior art, and its specific structure will not be described in detail herein.

[0102] In this application, by adopting the setting of the stir-fry key 600, when the valve rod 120 of the cock valve assembly 100 controls the burner 300 to be in the stir-fry state, the user needs to press the stir-fry key 600 to drive the first air hole 431 to be connected with the air outlet 422 through the driving component 440, preventing the user from accidentally operating the cock valve assembly 100 to cause the burner 300 to be directly in the stir-fry state, improving the safety of using the gas stove 700 with the stir-fry function, and preventing the stir-fry state of the gas stove 700 from affecting the user's food production without the user's awareness.

[0103] The embodiment of this application also provides a cooking device, including a stove body 710 and the combustion system of any of the above embodiments provided on the stove body 710.

[0104] Among them, the specific structure of the combustion system has been described in detail in the above embodiments, and will not be repeated here.

[0105] In this embodiment, the stove body 710 can be set as a gas stove 700 or an integrated stove.

[0106] The cooking device provided by the embodiment of the present application is provided with a combustion system. When the cock valve assembly 100 controls the burner 300 to be in the stir-fry state, at this time, the driving component 440 drives the valve core 430 to rotate in the valve body 420, so that the valve core 430 drives the first air hole 431 to communicate with the air outlet 422. Since the diameter of the air outlet 422 is greater than or equal to the diameter of the first air hole 431, and the diameter of the first air hole 431 is greater than the diameter of the second air hole 432, when the gas in the sub-ejector pipe 220 passes through the first air hole 431, the gas outlet volume of the gas can be increased, so that the gas outlet volume of the gas adapts to the burner 300 in the stir-fry state; when the cock valve assembly 100 controls the burner 300 to be in the stir-fry state, at this time, the driving component 440 drives the valve core 430 to move in the valve body 420, so that the valve core 430 drives the third air outlet hole 433 to be disengaged from the air outlet 422. At this time, the valve core 430 can be away from the air outlet 422, so as to prevent the valve core 430 from affecting the gas outlet of the air outlet 422. Since the diameter of the air outlet 422 is greater than the diameter of the third air outlet hole 433, the gas directly enters from the air inlet 421 and is discharged from the air outlet 422, thereby increasing the gas outlet volume, so that the gas outlet volume of the gas adapts to the burner 300 in the stir-fry state; the gas outlet volume of the gas in the valve body 420 on the sub-ejector pipe 220 is controlled by the valve core 430, so that the sub-ejector pipe 220 can make the burner 300 applicable to both the normal state and the stir-fry state, so that there is no need for an additional pipeline with a larger diameter to transport more gas to the burner 300, reducing the arrangement quantity of the pipelines for transporting gas, reducing the space occupied by the combustion system, and thus reducing the space occupied inside the gas stove 700.

[0107] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the invention disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application that follow the general principles of the present application and include known common knowledge or conventional technical means in the technical field not disclosed in the present application.
