However, the existing inner and outer ring synchronous fire function is usually integrated with the plug valve that controls the flame size, that is, two operations are performed through one knob, resulting in a more complex overall structure and more troublesome adjustment. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned prior art and provide a gas valve and a stove.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0007] The valve core is arranged in the valve cavity, the lower end of the valve stem is connected to the valve core, the upper end of the valve stem passes through the valve body and can extend above the stove panel, and the valve stem can drive the valve core to move between a first position and a second position relative to the valve body in a vertical direction; when the valve core is located at the first position, the inner ring gas channel and the outer ring gas channel are not connected; when the valve core is located at the second position, the inner ring gas channel and the outer ring gas channel are connected through the valve cavity.

[0008] In this solution, the plug valve and the synchronous fire regulating valve are separately arranged, which simplifies the overall structure of the gas valve and reduces the difficulty of processing. The plug valve and the synchronous fire regulating valve are controlled separately, and the user can directly operate the valve stem of the synchronous fire regulating valve to open or close the synchronous fire regulating valve, which reduces the difficulty of adjusting the synchronous fire of the inner and outer rings and improves the user's cooking experience.

[0009] Preferably, the valve cavity has a valve port and an air vent, the top opening of the valve cavity forms the valve port, and the peripheral side wall opening of the valve cavity forms the air vent; one of the valve port and the air vent is connected to the inner ring gas channel, and the other is connected to the outer ring gas channel; when the valve core is located at the first position, the valve core can block the valve port.

[0010] Preferably, the synchronous fire regulating valve also includes a retaining member, which is disposed below the valve core and fixed to the valve body, wherein the retaining member is at least partially located in the valve cavity, and the retaining member can be attracted to the valve core to keep the valve core in the second position.

[0011] In this solution, the retainer is used to ensure that the valve port of the synchronous fire regulating valve remains in a normally open state, ensure that the inner ring gas channel and the outer ring gas channel are always in a connected state, ensure the stability of the inner and outer ring synchronous fires, and prevent the synchronous fire regulating valve from being closed by hand. The suction method is simple to operate, has low alignment difficulty, and is easy to operate.

[0012] Preferably, the synchronous fire regulating valve further comprises a thermocouple, the thermocouple comprising a fixed portion, a movable portion and a reset portion, the movable portion being movably connected to the upper end of the fixed portion through the reset portion, the lower end of the fixed portion being fixedly connected to the valve body, and the valve stem being connected to an end of the movable portion away from the fixed portion in the vertical direction;

[0014] In this solution, when the stove is working, the temperature rises. According to the characteristics of the thermocouple, after the user presses the valve stem, the valve core can be adsorbed on the retaining member to maintain the valve port of the synchronous fire regulating valve normally open. After the stove finishes working, the temperature drops, the retaining member no longer adsorbs the valve core, and the valve core is reset to the first position under the action of the reset part to close the valve port of the synchronous fire regulating valve. The thermocouple structure can adapt to a high temperature environment and is suitable for stoves.

[0019] In this solution, the first sealing member is used to prevent gas leakage and improve safety.

[0020] Preferably, the synchronous fire regulating valve further comprises a limiter, which is fixed to the upper end surface of the retainer; the limiter has a concave cavity with an opening facing downward, the upper end surface of the limiter has a through hole penetrating in a vertical direction, the valve stem passes through the through hole and extends into the concave cavity, and the valve core is arranged in the concave cavity;

[0021] When the valve core is in the first position, the upper end surface of the valve core abuts against the upper wall surface of the concave cavity.

[0023] Preferably, the synchronous fire regulating valve also includes a reset member, which is sleeved on the valve stem, and the two ends of the reset member in the vertical direction are respectively abutted against the first sealing member and the limit member, and the reset member is used to apply a force to the first sealing member in a direction away from the limit member.

[0024] In this solution, the reset member indirectly resets the valve core by applying a force to the first sealing member, preventing the user from failing to pull up the valve core and causing the valve port of the synchronous fire regulating valve to not be completely closed, thereby improving the safety of the stove.

[0025] Preferably, the valve body comprises a main body, a raised portion and an abutment portion; the raised portion protrudes upward from the upper end surface of the main body, and the raised portion has a groove opening downward; the abutment portion is located between the raised portion and the valve cavity in the vertical direction, and a gap is formed between the lower end surface of the abutment portion and the valve port of the valve cavity in the vertical direction;

[0074] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0075] Example 1

[0076] like Figure 1 and Figure 2 As shown, this embodiment discloses a stove, comprising a stove panel 11, a fire cover, an ejector pipe and a gas valve 16. The gas valve 16 is connected to the fire cover through the ejector pipe to provide gas to the fire cover to ensure the combustion of the flame.

[0077] Specifically, Figure 1 and Figure 2 As shown, the fire cover is installed above the cooker panel 11 to generate flames. The fire cover includes an inner ring fire cover 12 and an outer ring fire cover 13, and the outer ring fire cover 13 is sleeved on the radial outer side of the inner ring fire cover 12. The ejector pipe includes an inner ring ejector pipe 14 and an outer ring ejector pipe 15, and the inner ring ejector pipe 14 is connected to the inner ring fire cover 12, and the outer ring ejector pipe 15 is connected to the outer ring fire cover 13.

[0078] like Figure 2-Figure 4 As shown, the gas valve 16 includes a plug valve 2 and a synchronous fire regulating valve 3. The plug valve 2 is used to control the gas entering the cooker, and can adjust the gas flux according to the needs of the user to adjust the size of the flame at the fire cover. The synchronous fire regulating valve 3 is used to control the gas concentration at the inner ring fire cover 12 and the outer ring fire cover 13 to be the same, so as to synchronize the inner ring flame and the outer ring flame, so that the fire power distribution is more uniform, so that the pot is heated more evenly, and the user's cooking experience is improved.

[0079] like Figure 3 As shown, the plug valve 2 has a first inner ring gas outlet 21 and a first outer ring gas outlet 22. The first inner ring gas outlet 21 is used to provide gas to the inner ring fire cover 12, and the first outer ring outlet is used to provide gas to the outer ring fire cover 13. The specific structure and working principle of the plug valve 2 belong to the prior art and will not be described here.

[0080] like Figure 3 and Figure 4 As shown, the synchronous fire regulating valve 3 includes a valve body 31 , a valve stem 32 , a valve core 33 , a retaining member 34 , a restoring member 35 and a second sealing member 36 .

[0081] like Figure 3 and Figure 4 As shown, the interior of the valve body 31 has an inner ring gas passage 311 , an outer ring gas passage 312 and a valve cavity 313 .

[0082] like Figure 2 and Figure 3As shown, the inner ring gas channel 311 extends in the horizontal direction, and the inner ring gas channel 311 has an inner ring air inlet 3111 and a second inner ring air outlet 3112. The inner ring air inlet 3111 of the inner ring gas channel 311 is connected to the first inner ring air outlet 21 of the plug valve 2, and the second inner ring air outlet 3112 of the inner ring gas channel 311 is connected to the inner ring ejector pipe 14. The outer ring gas channel 312 has an outer ring air inlet 3121 and a second outer ring air outlet 3122. The outer ring air inlet 3121 of the outer ring gas channel 312 is connected to the first outer ring air outlet 22 of the plug valve 2, and the second outer ring air outlet 3122 of the outer ring gas channel 312 is connected to the outer ring ejector pipe 15. The synchronous fire regulating valve 3 is arranged between the plug valve 2 and the ejector pipe, and the gas flowing out of the plug valve 2 flows into the corresponding ejector pipe through the gas channel corresponding to the synchronous fire regulating valve 3, and then flows to the corresponding fire cover through the ejector pipe.

[0083] like Figure 4 As shown, the valve cavity 313 has a valve port 3131 and a vent 3132, and the valve cavity 313 is connected to the inner ring gas channel 311 and the outer ring gas channel 312 through the valve port 3131 and the vent 3132. Specifically, the valve cavity 313 extends in the vertical direction, the top opening of the valve cavity 313 forms the valve port 3131, and the peripheral side wall opening of the valve cavity 313 forms the vent 3132. The inner ring gas channel 311 and the outer ring gas channel 312 are respectively arranged on both sides of the valve cavity 313, the inner ring gas channel 311 is connected to the vent 3132 of the valve cavity 313 through the connecting channel, and the outer ring gas channel 312 is connected to the valve port 3131 of the valve cavity 313 through the connecting channel, thereby realizing that the inner ring gas channel 311 and the outer ring gas channel 312 are connected to each other through the valve cavity 313.

[0084] like Figure 4 As shown, the valve core 33 is disposed in the valve cavity 313, the valve stem 32 extends in the vertical direction, the lower end of the valve stem 32 is connected to the valve core 33, and the upper end of the valve stem 32 passes through the valve body 31 and extends above the stove panel 11. The valve stem 32 can move in the vertical direction relative to the valve body 31, and because the valve stem 32 and the valve core 33 are fixedly connected, the valve stem 32 can drive the valve core 33 to move in the vertical direction between the first position and the second position relative to the valve body 31.

[0085] When the valve core 33 is in the first position, the valve core 33 blocks the valve port 3131 of the valve cavity 313, and the gas cannot flow from the inner ring gas channel 311 to the outer ring gas channel 312, nor can it flow from the outer ring gas channel 312 to the inner ring gas channel 311, that is, the inner and outer ring synchronous fire mode is in the closed state. When the valve core 33 is in the second position, the valve port 3131 of the valve cavity 313 is opened, the inner ring gas channel 311 and the outer ring gas channel 312 are connected to each other through the valve cavity 313, and the gas in the inner ring gas channel 311 and the outer ring gas channel 312 can be mixed with each other to adjust the gas concentration, that is, the inner and outer ring synchronous fire mode is in the open state.

[0086] In other alternative embodiments, the inner ring gas channel 311 may be in communication with the valve port 3131 , and the outer ring gas channel 312 may be in communication with the vent port 3132 .

[0087] Furthermore, if Figure 4 As shown, the valve body 31 includes a body 314, a protrusion 315 and an abutment 316. The inner ring gas channel 311, the outer ring gas channel 312 and the valve cavity 313 are all arranged on the body 314. The protrusion 315 protrudes upward from the upper end surface of the body 314, and the protrusion 315 has a groove 3151 opening downward. The abutment 316 is located between the protrusion 315 and the valve cavity 313 in the vertical direction, and there is a gap between the lower end surface of the abutment 316 and the valve port 3131 of the valve cavity 313 in the vertical direction, and the gas realizes the communication between the outer ring gas channel 312 and the valve port 3131 through the gap. The second sealing member 36 is sleeved on the valve stem 32 and is located in the groove 3151, and the lower end of the second sealing member 36 abuts against the abutment 316 to prevent gas leakage and improve safety.

[0088] like Figure 4 As shown, the retainer 34 is arranged below the valve core 33 and fixed on the valve body 31, and the retainer 34 is at least partially located in the valve cavity 313. When the valve core 33 moves to the second position, the retainer 34 can be sucked together with the valve core 33 to keep the valve core 33 in the second position, so that the valve port 3131 of the synchronous fire regulating valve 3 is maintained in a normally open state, ensuring that the inner ring gas channel 311 and the outer ring gas channel 312 are always in a connected state, ensuring the stability of the inner and outer ring synchronous fires, and preventing the synchronous fire regulating valve 3 from being closed by hand. The sucking method is simple to operate, has low alignment difficulty, and is easy to operate.

[0089] like Figure 4 and Figure 5As shown, the reset member 35 is disposed between the valve core 33 and the retaining member 34, and the two ends of the reset member 35 in the vertical direction are respectively in contact with the lower end surface of the valve core 33 and the upper end surface of the retaining member 34. The reset member 35 is used to apply a force in the vertical direction toward the valve port 3131 of the valve cavity 313 to the valve core 33, so as to help the valve core 33 to reset from the second position to the first position, and can keep the valve core 33 in the first position, so as to keep the valve port 3131 of the valve cavity 313 normally closed, and ensure that the inner and outer rings are closed in the synchronous fire mode.

[0090] The reset member 35 in this embodiment is a coil spring. In other alternative implementations, the reset member 35 may also be other reset structures that can achieve the above functions.

[0091] Specifically, Figure 4 and Figure 5 As shown, the synchronous fire regulating valve 3 also includes a thermocouple 4, which has a fixed portion 41, a movable portion 42 and a reset portion 43. The fixed portion 41 forms a retainer 34, the movable portion 42 forms a valve core 33, and the reset portion 43 forms a reset member 35. Specifically, the lower end of the valve cavity 313 is open, the fixed portion 41 is arranged at the lower end of the valve cavity 313 and is partially located outside the valve cavity 313, the lower end of the fixed portion 41 is fixedly connected to the valve body 31 and the connection with the lower end port of the valve cavity 313 is closed to prevent gas leakage. The lower end of the reset portion 43 is connected to the upper end of the fixed portion 41, the movable portion 42 is connected to the upper end of the reset portion 43 and is movably connected to the upper end of the fixed portion 41 through the reset portion 43, and the valve stem 32 is connected to one end of the movable portion 42 away from the fixed portion 41 in the vertical direction.

[0092] When the sensed temperature of the thermocouple 4 is greater than or equal to the preset temperature, the fixed portion 41 and the movable portion 42 are attracted, the valve core 33 moves from the first position to the second position, and the valve port 3131 of the valve cavity 313 is opened. When the sensed temperature of the thermocouple 4 is less than the preset temperature, the fixed portion 41 is not attracted to the movable portion 42, the valve core 33 remains in the first position, and the valve port 3131 of the valve cavity 313 is closed.

[0093] When the stove is working, the temperature rises. According to the characteristics of the thermocouple 4, after the user presses the valve stem 32, the valve core 33 can be adsorbed on the retaining member 34 to maintain the valve port 3131 of the synchronous fire regulating valve 3 normally open. After the stove finishes working, the temperature drops, the retaining member 34 no longer adsorbs the valve core 33, and the valve core 33 is reset to the first position under the action of the reset part 43 to close the valve port 3131 of the synchronous fire regulating valve 3. The structure of the thermocouple 4 can adapt to the environment with higher temperature and is suitable for stoves.

[0094] The working principle of the thermocouple 4 belongs to the prior art and will not be described in detail here.

[0095] In this embodiment, the plug valve 2 and the synchronous fire regulating valve 3 are separately provided, which simplifies the overall structure of the gas valve 16 and reduces the difficulty of processing. The plug valve 2 and the synchronous fire regulating valve 3 are controlled separately, and the user can directly operate the valve stem 32 of the synchronous fire regulating valve 3 to open or close the synchronous fire regulating valve 3, which reduces the difficulty of adjusting the synchronous fire of the inner and outer rings and improves the user's cooking experience.

[0096] Furthermore, when the amount of gas at the fire cover is small (for example, there is no flame at the outer ring fire cover 13, and a small flame at the inner ring fire cover 12), if the inner and outer ring synchronous fire mode is to be turned on at this time, the amount of gas may not be enough to support combustion and cause flameout. Therefore, it is preferred to set a reminder mark to remind the user that it is not recommended to turn on the inner and outer ring synchronous fire mode at this time. The reminder mark can be a reminder icon at the knob of the plug valve 2. When the user sees that the knob adjustment angle exceeds the reminder icon, he or she can realize that it is not recommended to turn on the inner and outer ring synchronous fire mode at this time. The reminder mark can also be in other forms, such as intelligent reminder methods such as voice broadcast, which can be designed according to actual needs.

[0097] Example 2

[0098] The structure of the cooker in this embodiment is basically the same as that in Embodiment 1, except that:

[0099] like Figure 6 and Figure 7 As shown, the synchronous fire regulating valve 3 includes a valve body 31 , a valve stem 32 , a valve core 33 , a retaining member 34 , a first sealing member 37 , a limiting member 38 and a reset member 35 .

[0100] like Figure 6 As shown, the retaining member 34 in this embodiment is a magnet, and the material of the valve core 33 is a metal material. The valve core 33 is attracted to the retaining member 34 by magnetic attraction, which has a simple structure and is easy to operate. The user can pull the valve stem 32 upward to reset the valve core 33, which has higher reliability. The process of opening and closing the synchronous fire regulating valve 3 is entirely manual, which reduces the power consumption of the synchronous fire regulating valve 3.

[0101] As shown in the figure, the first sealing member 37 is arranged in the valve cavity 313 and above the valve core 33. The first sealing member 37 is sleeved on the valve stem 32, and the first sealing member 37 can move along the vertical direction with the valve stem 32. When the valve core 33 is located at the first position, the first sealing member 37 blocks the valve port 3131 of the valve cavity 313, thereby closing the valve port 3131 of the synchronous fire regulating valve 3. The first sealing member 37 is used to prevent gas leakage and improve safety.

[0102] like Figure 6As shown, the stopper 38 is fixed on the upper end surface of the retaining member 34, and the stopper 38 has a concave cavity 381 with an opening facing downward. The upper end surface of the stopper 38 has a through hole penetrating in the vertical direction, and the valve stem 32 extends into the concave cavity 381 through the through hole, and the valve core 33 is arranged in the concave cavity 381. When the valve core 33 is in the first position, the upper end surface of the valve core 33 abuts against the upper wall surface of the concave cavity 381. The stopper 38 can limit the excessive upward movement of the valve core 33 when the user pulls up the valve stem 32, so as to prevent the first sealing member 37, the valve core 33 and other structures from being pulled out of the valve cavity 313, thereby ensuring the reliability of use.

[0103] like Figure 6 As shown, the reset member 35 is sleeved on the valve stem 32, and the two ends of the reset member 35 in the vertical direction are respectively in contact with the first sealing member 37 and the limit member 38, and the reset member 35 is used to apply a force to the first sealing member 37 in a direction away from the limit member 38. The reset member 35 indirectly resets the valve core 33 by applying a force to the first sealing member 37, preventing the user from pulling up the valve core 33 incompletely, thereby improving the safety of the stove.

[0104] The reset member 35 in this embodiment is a coil spring. In other alternative implementations, the reset member 35 may also be other reset structures that can achieve the above functions.

[0105] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the normal use of the device or component, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0106] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
