DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figures 1 to 6 The present application provides a technical scheme: a multi-gear adjusting valve for high-efficiency gas stove, comprising a valve body 1, the valve body 1 is provided with an inlet end 101 and an outlet end 102 at two ends respectively, an integrated communication part 103 is arranged on the outer wall of one side of the valve body 1, a valve stem 2 is rotatably installed in the communication part 103, a separation disc 104 is integrally arranged between the inner walls of the valve body 1, a first through hole 105 is formed through the upper surface of the separation disc 104, an adjusting disc 107 is rotatably arranged on the bottom of the separation disc 104 close to the inlet end 101, five second through holes 108 of different sizes and arranged in a ring shape are formed through the upper surface of the adjusting disc 107, the adjusting disc 107 and one end of the valve stem 2 located inside the valve body 1 are connected through a linkage mechanism, a feedback limiting mechanism capable of being connected in cooperation is arranged between the outer wall of the valve stem 2 and the inner wall of the communication part 103, and an adjusting knob 3 is fixedly connected to one end of the valve stem 2 located outside the valve body 1.

[0026] It should be noted that under the limitation of the feedback limiting mechanism, the valve stem 2 will trigger a touch feedback and generate a limit with the communication part 103 once every unit angle is rotated, the angle of each rotation of the valve stem 2 corresponds to the rotation angle of the adjusting disc 107, so that the valve stem 2 will have a second through hole 108 corresponding to the position of the first through hole 105 every unit angle is rotated. By rotating the valve stem 2 at different unit angles, different second through holes 108 are corresponded to the first through hole 105, so as to realize specific and accurate adjustment of the gas flow.

[0027] Please refer to Figure 2The linkage mechanism comprises a rotating shaft 106, a mounting blind hole is formed in the bottom surface of the partition disc 104, one end of the rotating shaft 106 is rotationally connected in the mounting blind hole, an adjusting disc 107 is integrally arranged on the outer wall of the rotating shaft 106, and the upper surface of the adjusting disc 107 is tightly attached to the bottom surface of the partition disc 104, a first bevel gear 109 is fixedly sleeved on the other end of the rotating shaft 106, the first bevel gear 109 is meshingly connected with a second bevel gear 110 on one side, and the second bevel gear 110 is fixedly sleeved on one end of the valve rod 2 located inside the valve body 1.

[0028] The opposite surfaces of the partition disc 104 and the adjusting disc 107 are tightly attached to each other to improve the overall sealing performance, and the gas can only pass through the second through hole 108 corresponding to the first through hole 105 through the partition disc 104, when the valve rod 2 is rotated by the adjusting knob 3, the valve rod 2 is rotated by different unit angles, and the adjusting disc 107 is also rotated by a corresponding angle, so that the first through hole 105 is correspondingly positioned with different second through holes 108, and the specific adjustment of the gas flow size is realized.

[0029] Please refer to Figure 3 and Figure 4 The five second through holes 108 are arranged in sequence in a counterclockwise direction from small to large in diameter.

[0030] According to different use scenarios, first, the diameters of the five second through holes 108 are determined, so that each second through hole 108 can correspond to different use scenarios, and the diameters are arranged in sequence in a counterclockwise direction (or clockwise direction) according to the size, so that when the angle of the adjusting disc 107 is adjusted by rotating the valve rod 2, the gas flow can be continuously and orderly adjusted from small to large, and the use convenience is improved.

[0031] Further, the second through hole 108 with the largest diameter is consistent with the diameter of the first through hole 105.

[0032] The second through hole 108 with the largest diameter is consistent with the diameter of the first through hole 105, which ensures that when the maximum gas flow position is reached, the gas can pass through the partition disc 104 with the largest flow area, meeting the demand for gas quantity when the gas stove is used for high-power cooking.

[0033] Further, the second through hole 108 with the largest diameter and the second through hole 108 with the smallest diameter are a blocking area, and the center points of the blocking area and the five second through holes 108 are evenly distributed in a ring shape.

[0034] Five second through holes 108 and blocking areas are respectively located in the corresponding areas of the six equal parts of the surface of the adjusting disc 107. When the valve rod 2 rotates by 60°, the adjusting disc 107 also rotates by 60°, so that the six equal parts of the corresponding areas are in position corresponding to the first through hole 105, the first through hole 105 is in position corresponding to one of the second through holes 108 or in position corresponding to the blocking area, and the gas flow can be completely cut off, so that the gear is clearly switched. The design of the annular uniform distribution ensures that the switching angle between each gear is uniform, the operation feels consistent, the stability and reliability of the adjustment are improved, and the gas flow regulation of the gas stove is more accurate and controllable.

[0035] Please refer to Figure 5 and Figure 6 The outer wall of the valve rod 2 is integrally provided with a sealing connecting ring 201, and the inner wall of the circumferential circle of the communication part 103 is provided with an annular connecting groove 111, and the sealing connecting ring 201 is rotationally connected in the annular connecting groove 111.

[0036] By providing the sealing connecting ring 201 on the outer wall of the valve rod 2, the annular connecting groove 111 is provided on the inner wall of the circumferential circle of the communication part 103, and the sealing connecting ring 201 is rotationally connected in the annular connecting groove 111, which plays a sealing role, prevents gas from leaking from the connection between the valve rod 2 and the communication part 103, and improves the safety of the regulating valve.

[0037] Further, the number of sealing connecting rings 201 and corresponding annular connecting grooves 111 is multiple.

[0038] The multiple sealing connecting rings 201 and annular connecting grooves 111 form multiple seals, improve the sealing performance, even if one of the sealing connecting rings 201 is slightly worn or fails to seal, the other sealing connecting rings 201 can still ensure good sealing effect, effectively reducing the possibility of gas leakage, further improving the safety and reliability of the regulating valve, and being suitable for occasions with strict requirements for gas leakage.

[0039] Further, the feedback limiting mechanism includes six annularly and uniformly distributed mounting grooves 202 provided on the outer wall of the circumferential circle of the valve rod 2, a clamping block 203 is slidably connected in each mounting groove 202, a spring 204 is fixedly connected between the bottom end of each clamping block 203 and the inner wall of the bottom of the corresponding mounting groove 202, the top end of each clamping block 203 is clamped in the corresponding clamping groove 112, and six clamping grooves 112 are provided in the corresponding positions on the inner wall of the circumferential circle of the communication part 103.

[0040] The feedback limiting mechanism makes the regulating valve have a clear gear feeling. When the user rotates the regulating knob 3, the user can clearly feel the switching of the gear, and the gear is automatically locked at each gear to prevent the valve rod 2 from rotating due to misoperation. At the same time, by limiting the rotation angle of the valve rod 2, the second through hole 108 on the adjusting disc 107 and the first through hole 105 on the separation disc 104 are corresponded at a specific position, realizing accurate gas flow regulation and improving the operation stability and accuracy of the regulating valve.

[0041] Further, the top end of each clamping block 203 and the inner wall of the clamping groove 112 are provided with corresponding arc structures.

[0042] The arc structure design makes the clamping block 203 more uniform in stress when clamped into and separated from the clamping groove 112, reduces the stress concentration phenomenon, thereby reducing the wear degree of the clamping block 203 and the clamping groove 112, and prolonging the service life of the feedback limiting mechanism. At the same time, this smooth matching mode also makes the user feel more comfortable when operating the regulating knob 3, improving the user experience.

[0043] Further, the valve body 1 is fixedly installed with a microcontroller 4 on one side of the outer wall, the gas outlet end 102 is fixedly installed with a flow sensor 5 on the inner wall, the regulating knob 3 is fixedly installed with an angle sensor 6 on one side of the surface, and the regulating knob 3 is further provided with a gear indicating lamp 301 and a flow indicating lamp 302 on the other side of the surface. The gear indicating lamp 301, the flow indicating lamp 302, the flow sensor 5 and the angle sensor 6 are electrically connected with the microcontroller 4.

[0044] The flow indicating lamp 302 can be provided with two colors of red and green. When the flow sensor 5 detects that the output gas flow of the gas outlet end 102 is consistent with the preset flow corresponding to the current second through hole 108, the green light is always on to indicate that the flow is normal. When the flow is inconsistent with the preset value, the red light is always on to warn, and the user needs to detect the overall setting, such as whether the separation disc 104 and the adjusting disc 107 are separated or the angle of the adjusting disc 107 is dislocated. The gear indicating lamp 301 can use six different colors to represent the corresponding gear state. Through the cooperation of the microcontroller 4, the flow sensor 5, the angle sensor 6, the gear indicating lamp 301 and the flow indicating lamp 302, the intelligent state display of the regulating valve is realized. The flow sensor 5 monitors the gas flow of the gas outlet end 102 in real time, the angle sensor 6 detects the rotation angle of the regulating knob 3, and the microcontroller 4 analyzes and processes these data to control the display of the gear indicating lamp 301 and the flow indicating lamp 302, providing the user with intuitive gas flow and gear information.

[0045] Working principle: gas enters the valve body 1 from the inlet end 101, and its flow is controlled by the second through hole 108 on the adjusting disc 107 corresponding to the first through hole 105. Rotating the adjusting knob 3 drives the valve rod 2, and the adjusting disc 107 is synchronously rotated through the linkage mechanism. Due to the limitation of the feedback limiting mechanism, the valve rod 2 rotates by a certain unit angle, and the second through hole 108 with different hole diameters corresponds to the first through hole 105, realizing accurate flow regulation. The sealing connecting ring 201 and the annular connecting groove 111 prevent gas leakage. The microcontroller 4 controls the gear indicator light 301 and the flow indicator light 302 to display according to the data of the flow sensor 5 and the angle sensor 6, providing intuitive information to ensure efficient, accurate, safe and intelligent gas flow regulation.

[0046] It should be noted that the specific model specifications of the microcontroller 4, the flow sensor 5, the angle sensor 6, the gear indicator light 301 and the flow indicator light 302 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method uses existing technology in the art, so it will not be described in detail.

[0047] The power supply of the microcontroller 4, the flow sensor 5, the angle sensor 6, the gear indicator light 301 and the flow indicator light 302 and its principle are clear to those skilled in the art, and will not be described in detail here.

[0048] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be changed and varied. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
