[0057] Embodiment 1

[0058] See also Figure 1-Figure 3 , this embodiment provides a gas valve.

[0059] Specifically, the gas valve includes a valve body 1 , an intelligent mode switch 2 , a valve shaft 3 and an intelligent mode trigger 4 .

[0060] Wherein, the intelligent mode switch 2 is arranged on the valve body 1 .

[0061] The valve shaft 3 is movably arranged on the valve body 1, and the valve shaft 3 has a fire-off position.

[0062] The intelligent mode trigger 4 is fixedly arranged on the valve shaft 3, and the valve shaft 3 can rotate along the first clockwise direction from the fire-off position to switch the gas valve to the manual mode, and the valve shaft 3 can rotate along the second clockwise direction from the fire-off position and drive the intelligent mode trigger 4 to trigger the intelligent mode switch 2, so that the gas valve switches to the intelligent mode, and the first clockwise direction is opposite to the second clockwise direction.

[0063] The gas valve provided in this embodiment has two modes, manual mode and intelligent mode, and the two modes are easy to switch. The valve shaft 3 rotates in the first clockwise direction from the fire-off position to switch the gas valve to the manual mode. The valve shaft 3 rotates in the second clockwise direction from the fire-off position. While rotating, the valve shaft 3 can drive the intelligent mode trigger 4 to trigger the intelligent mode switch 2, so that the gas valve switches to the intelligent mode. The existence of two modes makes it easy for users to choose according to their needs.

[0064] It should be noted that after the gas valve enters the intelligent mode, the gas valve can intelligently control the firepower to meet the cooking needs of the user. In the manual mode, the user rotates the valve shaft 3 to manually adjust the firepower.

[0065] Optionally, the first clockwise direction is counterclockwise, and the second clockwise direction is clockwise.

[0066] In one of the embodiments, an outer ring air outlet 16 is provided on the valve body 1 , and an on-off valve 161 is provided on the outer ring air outlet 16 . In the intelligent mode, the on-off valve 161 can control the on-off of the outer ring air outlet 16 .

[0067] Specifically, in the intelligent mode, the on-off valve 161 controls the on-off of the outer ring air outlet 16 according to a preset program.

[0068] Furthermore, a central air outlet 17 is also provided on the valve body 1. During operation of the gas valve, the mixture formed by the gas and air passes through the valve body 1 and can flow out from the outer ring air outlet 16 and the central air outlet 17. The mixture flowing out of the outer ring air outlet 16 flows to the outer ring fire cover of the burner to burn and form an outer ring fire, and the mixture flowing out of the central air outlet 17 flows to the central fire cover of the burner to burn and form a central fire. In the intelligent mode, when the firepower needs to be increased, the on-off valve 161 controls the outer ring air outlet 16 to be in a connected state, at which time the outer ring flame burns normally; when the firepower needs to be reduced, the on-off valve 161 controls the outer ring air outlet 16 to be in a disconnected state, at which time the outer ring flame is extinguished and only the central flame burns.

[0069] Optionally, the on-off valve 161 may be an electromagnetic stop valve or a bistable valve.

[0070] See also Figure 3-Figure 5 In one embodiment, a trigger protrusion 41 is provided on the smart mode trigger member 4, and a trigger button 21 is provided on the smart mode switch 2. The trigger protrusion 41 can rotate with the smart mode trigger member 4 to press the trigger button 21 or disengage from the trigger button 21.

[0071] When the trigger protrusion 41 rotates with the intelligent mode trigger member 4 to press the trigger button 21, the gas valve is in the intelligent mode, and the gas valve automatically controls the fire power.

[0072] Furthermore, in one of the embodiments, the smart mode switch 2 is staggered with a first surface 22 and a second surface 23, a guide slope 24 is provided on the smart mode switch 2 between the first surface 22 and the second surface 23, and the trigger button 21 is provided on the second surface 23; the trigger protrusion 41 can move in sequence through the first surface 22 and the guide slope 24 to press the trigger button 21.

[0073] Specifically, the first surface 22 and the second surface 23 are staggered relative to the axis of the valve shaft 3 , the first surface 22 is far away from the axis of the valve shaft 3 , and the second surface 23 is close to the axis of the valve shaft 3 .

[0074] The first surface 22 and the second surface 23 are staggered so that when the valve shaft 3 is initially rotated, during the process of the triggering protrusion 41 of the intelligent mode trigger member 4 being arranged relative to the first surface 22, there is always a gap between the triggering protrusion 41 and the first surface 22, thereby ensuring the smooth rotation of the intelligent mode trigger member 4; when the triggering protrusion 41 of the intelligent mode trigger member 4 rotates to be opposite to the guide bevel 24 and rotates along the guide bevel 24 to be arranged relative to the second surface 23, as the intelligent mode trigger member 4 continues to rotate, the triggering protrusion 41 finally rotates to press the trigger button 21, and the intelligent mode is triggered at this time.

[0075] The setting of the guiding inclined surface 24 ensures that the triggering protrusion 41 can smoothly rotate to press the triggering button 21 .

[0076] Specifically, the trigger protrusion 41 is a cam-shaped protrusion.

[0077] Further, see Figure 4 In one embodiment, a mounting hole 42 is provided through the intelligent mode trigger 4, and the inner wall of the mounting hole 42 includes a first abutting plane 421. The intelligent mode trigger 4 is sleeved on the outer periphery of the valve shaft 3 through the mounting hole 42, and the outer periphery of the valve shaft 3 is provided with a second abutting plane abutting against the first abutting plane 421.

[0078] When the intelligent mode trigger 4 is sleeved on the outer periphery of the valve shaft 3 through the mounting hole 42, the first abutment plane 421 abuts against the second abutment plane, which can not only realize the fixed installation of the intelligent mode trigger 4 on the valve shaft 3, but also ensure that the intelligent mode trigger 4 rotates synchronously with the valve shaft 3 during the rotation of the valve shaft 3, thereby ensuring that the gas valve can stably switch to the intelligent mode.

[0079] Specifically, a portion of material is cut off from the side surface of the valve shaft 3 to form the second abutting plane.

[0080] Further, in one embodiment, see Figure 3In order to ensure the accuracy of the installation position of the smart mode trigger 4, a positioning ring 11 is provided on the valve body 1, and a first positioning groove (not shown in the figure) that rotates with the positioning ring 11 is provided on the smart mode trigger 4.

[0081] Further, see Figure 1 and Figure 6 The valve body 1 includes an upper cover seat 12, a valve cup 13 and a valve core 14. The valve cup 13 is provided with an inner cavity. The upper cover seat 12 covers the upper end opening of the inner cavity of the valve cup 13. The valve core 14 is rotatably arranged in the inner cavity of the valve cup 13. The lower end of the valve shaft 3 passes through the upper cover seat 12 and is fixedly connected to the valve core 14 to drive the valve core 14 to rotate, thereby adjusting the fire power of the gas valve.

[0082] The positioning ring 11 is disposed on the upper surface of the upper cover seat 12 .

[0083] Optionally, the intelligent mode switch 2 is fastened to the upper cover seat 12 by screws.

[0084] Furthermore, in one of the embodiments, the gas valve also includes an ignition pressure plate 51 and an ignition switch 52. The ignition pressure plate 51 is rotatably mounted on the outer periphery of the valve shaft 3 and is always located on the upper side of the intelligent mode trigger 4. The ignition switch 52 is arranged on the valve body 1. The valve shaft 3 can be raised and lowered relative to the valve body 1 so that the ignition pressure plate 51 presses the ignition switch 52.

[0085] Specifically, a limiting ear assembly for limiting the rotation of the ignition pressure plate 51 is provided on the valve body 1. The limiting ear assembly includes two limiting ears arranged relatively at intervals, and a limiting space is formed between the two limiting ears. The pressing portion of the ignition pressure plate 51 is located in the limiting space and can be raised and lowered relative to the limiting space, but cannot be rotated relative to the limiting space.

[0086] In the off-fire position, the valve shaft 3 drives the ignition pressing plate 51 to descend to press the ignition switch 52, and the gas valve performs an ignition operation. When the valve shaft 3 is rotated, the ignition pressing plate 51 does not rotate with the valve shaft 3.

[0087] Specifically, a retaining spring 54 is sleeved on the outer periphery of the valve shaft 3 , and the retaining spring 54 abuts against the upper surface of the ignition pressure plate 51 to limit the upward movement of the ignition pressure plate 51 relative to the valve shaft 3 .

[0088] Further, see Figure 2 and Figure 3 In one of the embodiments, in order to enable the valve shaft 3 to rise and reset after the ignition operation is completed, the gas valve also includes a valve shaft reset component 53. The valve shaft reset component 53 is sleeved on the outer periphery of the valve shaft 3 and is located between the ignition pressure plate 51 and the intelligent mode trigger component 4. When the valve shaft 3 descends relative to the valve body 1, the valve shaft reset component 53 is compressed.

[0089] Optionally, the valve shaft reset member 53 is a compression spring. When the valve shaft 3 descends relative to the valve body 1, the valve shaft reset member 53 is compressed. At this time, the valve shaft reset member 53 continues to have elastic potential energy. After the user removes the downward pressure on the valve shaft 3, the valve shaft reset member 53 can help the valve shaft 3 move upward and reset.

[0090] In one embodiment, a second positioning groove 43 is provided on the smart mode trigger member 4 , and the lower end of the valve shaft reset member 53 is located in the second positioning groove 43 .

[0091] The provision of the second positioning groove 43 can ensure the position stability of the lower end of the valve shaft restoring member 53 .

[0092] Optionally, in smart mode, a preset program is started and the gas valve controls the fire power according to the bottom surface temperature of the cooker.

[0093] In manual mode, the user can adjust the firepower by rotating the valve shaft 3.

[0094] Optionally, in the manual mode, the gas valve has a plurality of gears, and the gas valve can be switched between the plurality of gears.

[0095] See also Figure 1 and Figure 6 The valve cup 13 of the valve body 1 is provided with an air inlet 15 , an outer ring air outlet 16 and a central air outlet 17 . Specifically, the air inlet 15 , the outer ring air outlet 16 and the central air outlet 17 are all communicated with the inner cavity of the valve cup 13 .

[0096] See also Figure 6 and Figure 7 In order to facilitate the switching of various gears in the manual mode, a clamping piece 31 is radially penetrated on the valve shaft 3, and a plurality of clamping grooves 121 located on the same circumference are provided on the lower surface of the upper cover seat 12. After the valve shaft 3 is pressed down, the clamping piece 31 can rotate with the valve shaft 3 to one of the clamping grooves 121 for clamping, and each clamping groove 121 corresponds to a gear position in the manual mode.

[0097] Optionally, the clamping member 31 is a shaft-type part.

[0098] Specifically, the lower surface of the upper cover seat 12 is provided with a first positioning boss 122, a second positioning boss 123 and a third positioning boss 124. The number of the third positioning bosses 124 is at least two.

[0099] Specifically, in this embodiment, there are four third positioning bosses 124. A fire-off positioning groove 125 is formed between the first positioning boss 122 and the second positioning boss 123. A slot 121 formed between the second positioning boss 123 and a third positioning boss 124 adjacent to the second positioning boss 123 is a first slot. In a direction away from the second positioning boss 123, the plurality of slots 121 are respectively a first slot, a second slot, a third slot, a fourth slot and a fifth slot. It should be noted that the side of the fourth third positioning boss 124 at the end away from the third third positioning boss 124 is the fifth slot.

[0100] When the clamp 31 is clamped in the off-fire positioning groove 125, the valve shaft 3 is in the off-fire position. When the clamp 31 is rotated 90° in the first clockwise direction, it can be clamped with the first clamping groove; then, each time the clamp 31 is rotated 30° in the first clockwise direction, it rotates to the next clamping groove 121. When the valve shaft 3 needs to be reset to the off-fire position, the valve shaft 3 can be rotated in the reverse direction.

[0101] It should be noted that, in the manual mode, when the valve shaft 3 is in different gear positions, the fire power of the gas valve is different.

[0102] In order to achieve different fire powers of the gas valve when the valve shaft 3 is in different gears in the manual mode, a guide cavity 141 is provided in the valve core 14 , and the air inlet 15 is communicated with the guide cavity 141 .

[0103] A plurality of central flow guide holes 142 are disposed on the side of the valve core 14 . Each central flow guide hole 142 is communicated with the flow guide cavity 141 . The central flow guide hole 142 can rotate to communicate with the central air outlet 17 .

[0104] Furthermore, three central flow guide holes 142 are arranged on the side of the valve core 14 , wherein one central flow guide hole 142 has a larger flow area, and the other two central flow guide holes 142 have smaller flow areas.

[0105] A plurality of outer ring flow guide holes 143 are disposed on the side of the valve core 14 . Each outer ring flow guide hole 143 is communicated with the flow guide cavity 141 . The outer ring flow guide holes 143 can rotate to communicate with the outer ring air outlet 16 .

[0106] Furthermore, four outer ring guide holes 143 are arranged on the side of the valve core 14, among which two outer ring guide holes 143 have a larger flow area, and the other two outer ring guide holes 143 have a smaller flow area, the two outer ring guide holes 143 with smaller flow areas have the same central angle, and the two outer ring guide holes 143 with larger flow areas have different central angles.

[0107] The gas enters the guide cavity 141 through the gas inlet 15 , and the gas in the guide cavity 141 can flow to the central gas outlet 17 through the central guide hole 142 ; the gas in the guide cavity 141 can flow to the outer ring gas outlet 16 through the outer ring guide hole 143 .

[0108] Furthermore, in order to ensure that the side of the valve core 14 is sealed and abutted against the inner wall of the inner cavity of the valve cup 13, the lower end of the valve shaft 3 is fixedly connected with a connecting shaft 32, and the connecting shaft 32 is fixedly connected to the valve core 14. A valve core abutment ring 33 is movably sleeved on the connecting shaft 32, and the valve core abutment ring 33 abuts against the upper surface of the valve core 14. A valve core elastic member 34 is sleeved on the outer periphery of the connecting shaft 32, and the upper end of the valve core elastic member 34 elastically abuts against the lower surface of the valve shaft 3, and the lower end of the valve core elastic member 34 abuts against the valve core abutment ring 33. The valve core elastic member 34 always accumulates elastic potential energy to press the valve core abutment ring 33 downward, so that the valve core 14 is pressed down and sealed and abutted against the inner wall of the inner cavity of the valve cup 13.

[0124] Specifically, when steaming or stewing ingredients, when the temperature at the bottom of the pot reaches the first set temperature of 100°C, the on-off valve 161 continues to control the outer ring air outlet 16 to be opened and lasts for the first time period of 5 minutes; then the on-off valve 161 controls the outer ring air outlet 16 to be cut off, and at this time only the central fire cover connected to the central air outlet 17 is burning, and the outer ring fire cover connected to the outer ring air outlet 16 is in an off state, and after a second time period of 2 minutes, the on-off valve 161 controls the outer ring air outlet 16 to be opened; and this process is repeated until cooking is completed.

[0125] In other embodiments, the first duration and the second duration are set as needed, and no further restrictions are imposed herein.

[0126] Specifically, when the gas valve is working, the user presses down the valve shaft 3, and the valve shaft 3 drives the ignition pressure plate 51 to move downward. After the ignition pressure plate 51 moves downward, it presses the ignition switch 52. After the controller of the gas stove receives the signal that the ignition switch 52 is triggered, it sends out a pulse ignition spark.
