[0034] A gas stove refers to a kitchen appliance that uses gas fuels such as liquefied petroleum gas, coal gas, and natural gas for direct fire heating. When the gas stove is working, the gas enters the stove from the air inlet pipe, enters the burner after being adjusted by the gas valve, and is ejected from the fire hole of the burner and ignited by the ignition device to form a flame, which is used to heat the cooker placed on the pot support. The gas stoves in the prior art mostly adjust the fire power of the gas stove manually. When the user is a certain distance away from the stove, it is inconvenient to adjust the fire power of the gas stove, which affects the user experience.

[0035] In order to solve the above problems, the utility model proposes a gas furnace regulating device, which aims to provide a gas furnace regulating device which can automatically adjust the fire power. Figures 1 to 3 The present invention is a schematic structural diagram of an embodiment of a gas furnace regulating device provided by the present invention.

[0036] Please refer to Figures 1 to 3 The utility model proposes a gas furnace regulating device 1000, comprising a burner 1, a gas valve 2, a driving mechanism 3 and a remote controller, wherein the gas valve 2 comprises a valve body 21 and a valve core 22 movably arranged in the valve body 21, wherein the valve body 21 comprises an air inlet end 211 and an air outlet end 212, wherein the air inlet end 211 is used to connect to a gas source, and the air outlet end 212 is connected to the burner 1; the output end of the driving mechanism 3 is connected to the valve core 22 to adjust the rotation angle of the valve core 22 so that the valve core 22 controls the air outlet volume of the air outlet end 212; the remote controller is wirelessly connected to the driving mechanism 3 for communication, and is used to control the driving mechanism 3 to drive the valve core 22 to rotate.

[0037] In the technical solution of the utility model, a gas furnace adjustment device 1000 is proposed, including a burner 1, a gas valve 2, a driving mechanism 3 and a remote control. The driving mechanism 3 is wirelessly controlled by the remote control to drive the valve core 22 to rotate to adjust the gas output of the gas outlet end 212, thereby adjusting the amount of gas supplied to the burner 1 for use, so that the user can adjust the firepower of the gas furnace at a distance even if he is not next to the gas furnace, which is convenient for the user's operation and improves the user's experience.

[0038] In an optional embodiment, in order to facilitate the driving mechanism 3 to rotate and adjust the valve core 22, the driving mechanism 3 includes a rotating motor 31 and a transmission gear 32, and the transmission gear 32 includes a first transmission gear 321 and a second transmission gear 322. The first transmission gear 321 is connected to the main shaft of the rotating motor 31, and the second transmission gear 322 is sleeved on the valve core 22. The first transmission gear 321 and the second transmission gear 322 are meshed with each other. In the actual design process 1, the valve core 22 can be driven directly by the motor, or it can be driven by the transmission mechanism to adjust the valve core 22 more finely. Please refer to Figure 1 In this embodiment, the main shaft of the rotating motor 31 is connected to the first transmission gear 321, and the second transmission gear 322 is sleeved on the valve core 22. The torque is transmitted by the meshing of the first transmission gear 321 and the second transmission gear 322, so that the rotating motor 31 can rotate and adjust the valve core 22, which not only realizes the automatic adjustment of the valve core 22, but also ensures the stability of the adjustment.

[0039] In an optional embodiment, the second transmission gear includes a main gear 3221 and a sub-gear 3222, the main gear 3221 is meshed with the sub-gear 3222, the main gear 3221 is meshed with the first transmission gear 321, and the sub-gear 3222 is sleeved on the valve core. In the actual design process, the second transmission gear can be directly designed as an integrated structure, or it can be designed as a split structure composed of multiple parts of gear structures. Please refer to Figure 2 and Figure 3 In this embodiment, the second transmission gear is composed of a main gear 3221 and a sub-gear 3222 that are meshed and connected along the extension direction of the valve core. This makes it easy for the main gear 3221 and the sub-gear 3222 to be in the two states of engagement and disengagement, so as to realize the switching of the gas furnace adjustment device between automatic adjustment and manual adjustment to meet the user's usage needs in different usage scenarios.

[0040] Furthermore, in order to facilitate the remote controller to adjust the fire power of the gas stove, the gas stove adjustment device 1000 further includes a control panel 4, the control panel 4 is provided with a signal receiving end capable of receiving a radio signal sent by the remote controller, and the control panel 4 is electrically connected to the driving mechanism 3. Figure 1 After the user presses the adjustment command of the remote control, the radio signal sent by the remote control is received by the signal receiving end on the control board 4, and then the rotating motor 31 is controlled to rotate to drive the valve core 22 to rotate relative to the valve body 21, so as to adjust the gas output volume of the gas outlet end 212, thereby achieving the effect of adjusting the fire power of the gas stove by the remote control at a distance.

[0041] In an optional embodiment, in order to realize the automatic opening and closing of the gas stove, the gas stove adjustment device 1000 further includes a contact switch 41, which is in contact with the second transmission gear 322 and electrically connected to the rotating motor 31 to adjust the rotation angle of the rotating motor 31. The contact switch 41 can be set to abut against the gear shaft of the second transmission gear 322 to sense the rotation position of the valve core 22, and then sense the size of the gas output of the gas outlet end 212, so that the contact switch 41 can sense and control when the valve core 22 is in the two critical states of completely blocking the passage between the gas inlet end 211 and the gas outlet end 212 or completely releasing the passage between the gas inlet end 211 and the gas outlet end 212, thereby automatically adjusting the ignition or extinguishing of the gas stove.

[0042] Furthermore, the contact switch 41 is telescopically connected to the control panel 4, and a matching groove 3223 corresponding to the contact switch 41 is formed on the outer periphery of the second transmission gear 322. The contact switch 41 can be in contact with and out of contact with the matching groove 3223 as the second transmission gear 322 rotates. Figures 1 to 3 In this embodiment, the contact switch 41 is telescopically connected to the control panel 4, and the adjustment stroke of the valve core 22 in the valve body 21 corresponds to the length of the matching groove 3223 on the second transmission gear 322. When the rotary motor 31 rotates, the contact switch 41 abuts against the gear shaft of the second transmission gear 322 but does not enter the matching groove 3223. At this time, the valve core 22 does not connect the air inlet end 211 and the air outlet end 212, and the gas furnace is in a flameout state. When the second transmission gear 322 rotates with the drive of the rotary motor 31 until the contact switch 41 enters the matching groove 3223, the contact switch 41 pops out from the control panel 4. At this time, the valve core 22 is in a state of connecting the air inlet end 211 and the air outlet end 212, and the valve core 22 continues to connect with the drive of the second transmission gear 322. As the valve 22 continues to rotate, the passage between the air inlet end 211 and the air outlet end 212 gradually increases, and the contact switch 41 in the matching groove 3223 can adjust the fire of the gas stove. When the contact switch 41 is disengaged from the matching groove 3223 as it rotates, the valve core 22 blocks the passage between the air inlet end 211 and the air outlet end 212, so that the remote control and the control panel 4 can control and adjust the rotation of the valve core 22. Optionally, in order to make the contact switch 41 transition more smoothly in the matching groove 3223, the matching groove 3223 is arranged in a continuous transitional concave-convex shape along the circumference of the valve core 22. Please refer to Figure 3The matching groove 3223 presents a continuous arc transition on the gear shaft of the second transmission gear 322, so that the contact switch 41 can change its contact degree with the matching groove 3223 more smoothly when it moves, thereby ensuring the contact stability of the contact switch 41.

[0043] In an optional embodiment, in order to facilitate the gas stove to alternate between manual control and automatic control, the valve core 22 can reciprocate relative to the valve body 21 along the axial direction and has a stroke that can disengage the main gear 3221 from the auxiliary gear 3222. Figures 1 to 3 The valve core 22 can move axially relative to the valve body 21, so that the main gear 3221 and the sub-gear 3222 are out of meshing state, so that the torque can no longer be transmitted to the valve core through the first transmission gear, so that the user can manually twist the valve core 22 for adjustment. Furthermore, in order to facilitate the valve core 22 to be reset to the state of automatically adjusting the size of the fire after manual rotation, a rebound member can be provided between the valve core 22 and the valve body 21 so that after the user no longer applies pressure to the valve core 22, the valve core 22 rebounds and resets to restore the main gear 3221 and the sub-gear 3222 to the meshing state. In this way, the gas furnace can be conveniently switched between the manual adjustment mode and the automatic adjustment mode achieved by the remote control to meet the needs of users in different scenarios.

[0044] Furthermore, in order to facilitate the user to twist the valve core 22 for manual adjustment, the gas stove adjustment device 1000 further includes a knob 5, and the knob 5 is sleeved on one end of the valve core 22 away from the valve body 21. Figure 1 The valve core 22 is clamped at one end of the valve core 22, so that the user can adjust the valve core 22 more effortlessly by pressing down and twisting the knob 5. The side wall of the knob 5 can be provided with knurling to increase the friction between the user's fingers to improve the anti-slip effect. In addition, the ranges of fire power such as high fire, medium fire, and low fire can be marked on the knob 5 to correspond to the position of the matching groove 3223 to prompt the user and facilitate the user to manually adjust the fire power of the gas stove.

[0045] The utility model also provides a gas stove, which includes a gas stove regulating device 1000, a stove table and a gas source. The gas stove regulating device 1000 is arranged on the stove table. A stove rack is arranged above the stove table to place pots. A burner 1 is correspondingly arranged below the stove rack to burn gas to provide a fire source; the gas source is connected to the gas inlet end 211 to supply gas to the burner 1. The specific structure of the gas stove regulating device 1000 refers to the above embodiment. Since the gas stove regulating device 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0046] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
