[0023] Reference Figure 1In an embodiment of the present invention, a single-valve multi-burner structure includes a valve 100 and a combustion unit 103. The valve 100 is connected to at least three combustion units 103. It can be understood that the valve 100 is connected to an air inlet pipe 101 and an air outlet pipe 102, and the air outlet pipe 102 is used to connect the combustion unit 103. The valve 100 includes a valve body 110 and a valve core 120. The valve core 120 is rotatably connected to the valve body 110. The valve body 110 is provided with at least three channels. The three channels are arranged along the circumference of the valve core 120 and are all connected to the combustion unit 103. The valve body 110 is provided with an air inlet channel 111. The valve core 120 has an inner cavity 127 connected to the air inlet channel 111. The valve core 120 is provided with three gas distribution components connected to the inner cavity 127. The three gas distribution components correspond to the three channels respectively. The gas distribution components include a first through hole 124, a second through hole 125 and a gas distribution groove 126. The first through hole 124, the second through hole 125 and the gas distribution groove 126 are provided. 4 and the second through hole 125 are located in the gas distribution groove 126, the inner diameter of the first through hole 124 is larger than the inner diameter of the second through hole 125. It can be understood that the gas can enter the valve 100 from the intake pipe 101, and enter the multiple combustion units 103 through the intake channel 111, the inner cavity 127 of the valve core 120, the gas distribution component, and the channel. In addition, the rotating valve core 120 can make the channel communicate with the first through hole 124 and the second through hole 125 respectively to adjust the size of the ventilation volume, thereby adjusting the firepower of the combustion unit 103, making the adjustment convenient and flexible, and improving the use experience.

[0024] It can be understood that, in the present embodiment, the valve 100 is provided to connect the three combustion units 103 and control the gas output of each combustion unit 103 so as to control the firepower thereof. The three gas distribution components are respectively the first gas distribution portion 121, the second gas distribution portion 122 and the third gas distribution portion 123 arranged at intervals along the axial direction of the valve core 120, and the first gas distribution portion 121, the second gas distribution portion 122 and the third gas distribution portion 123 are staggered around the axis of the valve core 120. At the same time, the three channels provided are respectively the first channel 112, the second channel 113 and the third channel 114 connecting different combustion units 103, the first gas distribution portion 121 is connected to the first channel 112, the second gas distribution portion 122 is connected to the second channel 113, and the third gas distribution portion 123 is connected to the third channel 114. Specifically, referring to Figure 5 , the gas distribution groove 126 is recessed and arranged in the outer peripheral wall of the valve core 120. For the first gas distribution portion 121, the gas distribution groove 126 extends along the outer peripheral wall of the valve core 120, wherein three first through holes 124 and second through holes 125 are arranged, and the first through holes 124 and the second through holes 125 are arranged alternately along the circumferential direction of the valve core 120; Figure 4There are two second gas distribution parts 122, which are spaced apart along the circumference of the valve core 120, and the gas distribution groove 126 extends along the outer peripheral wall of the valve core 120. In the same gas distribution groove 126, the first through hole 124 and the second through hole 125 are respectively arranged at both ends of the gas distribution groove 126; Figure 6 For the third gas distribution part 123, the gas distribution groove 126 extends along the outer peripheral wall of the valve core 120, and the first through hole 124 and the second through hole 125 are respectively arranged at both ends of the gas distribution groove 126. It can be understood that the inner diameter of the first through hole 124 is greater than the inner diameter of the second through hole 125, so the ventilation efficiency of the first through hole 124 is greater than the ventilation efficiency of the second through hole 125, so that the combustion unit 103 can have a greater firepower, and the ventilation efficiency of the gas distribution groove 126 is determined by the area of ​​its cross section. In this embodiment, the ventilation efficiency of the gas distribution groove 126 is between the ventilation efficiency of the first through hole 124 and the ventilation efficiency of the second through hole 125.

[0025] It is understood that the valve core 120 can rotate within the valve body 110 to different positions, including a first position, a second position, and a third position. Figure 7 When the valve core 120 is in the first position, the first through hole 124 of the first air distribution unit 121 is connected to the first channel 112, the first through hole 124 of the second air distribution unit 122 is connected to the second channel 113, and the first through hole 124 of the third air distribution unit 123 is connected to the third channel 114. At this time, the apertures of the first channel 112, the second channel 113 and the third channel 114 connecting to the inner cavity 127 are relatively large, so that the three combustion units 103 can be in the high fire gear at the same time.

[0026] Reference Figure 8 When the valve core 120 is in the second position, the gas distribution groove 126 of the first gas distribution part 121 is connected to the first channel 112, the gas distribution groove 126 of the second gas distribution part 122 is connected to the second channel 113, and the gas distribution groove 126 of the third gas distribution part 123 is connected to the third channel 114. It can be understood that the gas can enter the gas distribution groove 126 through the first through hole 124 and the second through hole 125, and flow from the gas distribution groove 126 to the channel connected thereto. Therefore, the gas ventilation efficiency at this time is lower than the ventilation efficiency when the valve core 120 is in the first position, and the three combustion units 103 are simultaneously in the medium fire gear.

[0027] Reference Fig. 9, the valve core 120 is located in the third position, the second through hole 125 of the first gas distribution part 121 is connected to the first channel 112, the second through hole 125 of the second gas distribution part 122 is connected to the second channel 113, and the second through hole 125 of the third gas distribution part 123 is connected to the third channel 114. It can be understood that the gas can enter the channel connected thereto through the second through hole 125. Since the aperture of the second through hole 125 is small and the ventilation efficiency is lower than the ventilation efficiency of the gas distribution groove 126 and the first through hole 124, the gas ventilation efficiency at this time is further reduced than the ventilation efficiency when the valve core 120 is in the second position, and the three combustion units 103 are simultaneously in the low-fire gear.

[0028] It is understandable that the valve core 120 can also be in the fourth position and the fifth position. Fig.10 When the valve core 120 is located at the fourth position, the first channel 112 and the second channel 113 can be connected to the inner cavity 127 through the first gas distribution part 121 and the second gas distribution part 122 respectively, and the third channel 114 cuts off the connection with the inner cavity 127. Specifically, the second channel 113 is connected to another second gas distribution part 122 located on the peripheral wall of the valve core 120 at this time, and the second gas distribution part 122 includes a first through hole 124, a gas distribution groove 126 and a second through hole 125. When the valve core 120 rotates, the second channel 113 can be switched to be connected to the first through hole 124, the gas distribution groove 126 and the second through hole 125 respectively, so as to adjust the firepower of the combustion unit 103 connected to the second channel 113. At this time, the first channel 112 remains connected to the inner cavity 127 of the valve core 120 through the first air distribution unit 121. When the valve core 120 is rotated, the firepower of the combustion units 103 connected to the first channel 112 can be adjusted at the same time, that is, only two of the combustion units 103 are adjusted at this time, and one of the combustion units 103 is in a closed state.

[0029] Further, refer to Fig.11 When the valve core 120 is located at the fifth position, the first channel 112 can be connected to the inner cavity 127 through the first gas distribution part 121, and the second channel 113 and the third channel 114 are cut off from the inner cavity 127. It can be understood that the second gas distribution part 122 is located at a position not connected to the second channel 113, and the third gas distribution part 123 is located at a position not connected to the third channel 114. At this time, the rotating valve core 120 can only adjust the firepower of the combustion unit 103 connected to the first channel 112. It can be understood that more than three channels can be set on the valve body 110 to connect more than three combustion units 103 at the same time. By rotating a valve core 120, it is possible to adjust one or several combustion units 103 individually, or adjust the firepower of all combustion units 103 at the same time, which can improve the convenience of adjustment and the use experience.

[0030] Further, refer to Figure 2 The valve body 110 is provided with a matching channel 115 for inserting the valve core 120, and the radial outer wall of the valve core 120 and the inner wall of the matching channel 115 are matched with each other in a conical surface. At the same time, a pressure cap 116 is provided on the valve body 110, and a spring 117 is provided between the pressure cap 116 and the valve body 110 to press against the end of the valve core 120. The spring 117 presses against one end of the valve core 120, so that the radial outer wall of the valve core 120 presses against the inner wall of the matching channel 115, thereby achieving a sealing function and facilitating the positioning of the valve core 120 during assembly.

[0031] According to an embodiment of the second aspect of the present invention, a gas stove is provided, comprising the above-mentioned single-valve multi-burner structure. It can be understood that since the gas stove comprises all the technical features of a single-valve multi-burner structure, the gas stove also has all the beneficial effects of a single-valve multi-burner structure.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
