Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] The following detailed description, in conjunction with the accompanying drawings, illustrates the technical solution of an ultra-thin valve body provided by various embodiments of this utility model.

[0029] Reference Figures 1 to 9As shown, this utility model embodiment provides an ultra-thin valve body, including a valve body 1, a valve seat 2, a potentiometer 3, a rotating shaft 4, a valve core 5, a lever 6, and a solenoid valve 7. The valve seat 2 is disposed on the valve body 1, and the valve seat 2 is connected to the valve body 1 by two screws 12. The potentiometer 3 is connected to the valve seat 2 by two screws 12. The valve seat 2 is provided with a micro switch 20 connected by screws 12. The rotating shaft 4 extends into the valve body 1 through the potentiometer 3 and the valve seat 2. The valve seat 2 is provided with a rotating stop block. 8. The gear block 8 is sleeved on the valve core 5. The valve core 5 is connected to the bottom of the rotating shaft 4. The rotating shaft 4 can slide on the valve core 5. The bottom of the rotating shaft 4 is provided with a valve needle 40. The valve core 5 is provided with a fixed circular plate 401. The valve needle 40 is sleeved with a return spring 402. The two ends of the return spring 402 are respectively connected to the circular plate 401 and the bottom of the rotating shaft 4. The solenoid valve 7 is located inside the valve body 1. The lever 6 is rotatably connected inside the valve body 1 and is linked with the valve needle 40 and the solenoid valve 7.

[0030] When the rotating shaft 4 is rotated, the shaft 4 drives the shift block 8 to rotate. At the same time, through the sliding engagement between the protrusion 41 and the first groove 51 on the valve core 5, the valve core 5 is displaced within the valve body 1. During the movement, the valve needle 40 at the bottom of the rotating shaft 4 compresses or releases the return spring 402. The interaction between the valve needle 40 and the inner disc 401 of the valve core 5 ensures that the rotating shaft 4 can slide flexibly and has a return capability.

[0031] Potentiometer 3 changes its resistance value by rotating shaft 4, converting the mechanical rotation signal into an electrical signal, which is used to provide feedback on the current regulation status or to participate in the control of gas flow.

[0032] The micro switch 20 works in conjunction with the gear block 8. When the gear block 8 rotates, its specific structure triggers the micro switch 20 to switch the circuit on and off, thereby controlling ignition, gas supply and other aspects.

[0033] The first baffle 61 at one end of the lever 6 acts on the valve needle 40, which is connected to the bottom of the rotating shaft 4. The rotating shaft 4 moves axially downward, and the valve needle 40 pushes the lever 6 to rotate in the gas chamber 105. The second baffle 62 at the other end of the lever 6 acts on the solenoid valve 7, thereby controlling the passage to open and allow gas to pass through.

[0034] This utility model realizes the coordinated operation of multiple components of the gas valve. The potentiometer 3, the gear block and the micro switch 20 work together to take into account both precise adjustment of firepower and safety control. The design of the return spring 402 and the valve needle 40 ensures the stability and resettlement of the operation of the rotating shaft 4. The linkage between the lever 6 and the solenoid valve 7 and the valve needle 40 realizes the on-off control of gas.

[0035] Specifically, the valve body 1 is provided with an air inlet 101, a solenoid valve mounting cavity 102, a small flame air outlet 103, and a large flame air outlet 104. The solenoid valve mounting cavity 102 is connected to the air inlet 101. The valve body 1 is provided with an air chamber 105 that is connected to the solenoid valve mounting cavity 102. The air chamber 105 is connected to the small flame air outlet 103 and the large flame air outlet 104. The solenoid valve 7 is installed in the solenoid valve mounting cavity 102. The lever 6 is rotatably connected in the air chamber 105. The two ends of the lever 6 are respectively provided with a first baffle 61 and a second baffle 62. The first baffle 61 is located at the valve needle 40, and the second baffle 62 is located at the solenoid valve 7, which are used to control the opening and closing of the air passage.

[0036] Specifically, the bottom of the rotating shaft 4 is provided with a protrusion 41, and the valve core 5 and the stop block 8 are respectively provided with a first groove 51 and a second groove 81 that slide in cooperation with the protrusion 41;

[0037] When the rotating shaft 4 rotates, the protrusion 41 slides in the first groove 51 of the valve core 5 and the second groove 81 of the gear block 8, causing the valve core 5 and the gear block 8 to rotate synchronously.

[0038] The rotation of valve core 5 changes the connection state between its gas outlet 52 and gas chamber 105, small flame gas outlet 103 and large flame gas outlet 104, thereby regulating the flow rate and direction of gas; the rotation of gear block 8 triggers micro switch 20 to realize circuit control, and its cooperation with steel ball 92 and gear slot 80 provides clear gear feedback, allowing users to clearly perceive the current firepower level by touch;

[0039] This combination allows the operation of the rotating shaft 4 to be precisely transmitted to the valve core 5 and the gear block 8, enabling accurate adjustment of gas flow and clear division of firepower levels. Users can adjust the firepower intuitively and conveniently, while the triggering of the micro switch 20 ensures the synchronization of operation and circuit control, improving safety and convenience of use.

[0040] Specifically, the valve body 1 is provided with mounting screws 9, and the mounting screws 9 are connected to a movable spring 91. A steel ball 92 is connected to the end of the movable spring 91. The stop block 8 is provided with nine stop grooves 80. Rotation of the stop block 8 causes the steel ball 92 to rotate within the nine stop grooves 80. (Refer to...) Figure 9 As shown.

[0041] When the gear block 8 is rotated, the moving spring 91 pushes the steel ball 92 to roll in the nine gear slots 80. Each time the ball rolls to a gear slot 80, it corresponds to a fixed power level.

[0042] At this time, the rotating shaft 4 drives the valve core 5 to rotate to the corresponding position, changing the flow of gas and realizing the switching of different firepower; the moving spring 91 provides continuous pressure to the steel ball 92, ensuring that the steel ball 92 is stably stuck in the gear slot 80, preventing the gear block 8 from rotating accidentally due to external force; the design of nine gear slots 80 provides a variety of firepower options to meet the firepower needs of different cooking scenarios.

[0043] The combination of steel ball 92 and gear slot 80 gives the gear adjustment a distinct sense of tactile feedback and positioning effect, allowing users to accurately adjust to the required firepower. At the same time, it enhances the stability and reliability of the adjustment structure and reduces the problem of unstable firepower caused by misoperation.

[0044] Specifically, the valve core 5 is provided with a plurality of air outlet holes 52.

[0045] The valve core 5 has several air outlets 52 that form different communication combinations with the air chamber 105, the small flame air outlet 103 and the large flame air outlet 104, depending on the rotation position of the valve core 5.

[0046] When the valve core 5 is rotated to a specific position, some of the gas outlets 52 are connected to the gas chamber 105, and the gas flows through these gas outlets 52 to the small flame outlet 103 to achieve small flame combustion; as the valve core 5 is rotated further, more gas outlets 52 are connected, and the gas not only flows to the small flame outlet 103, but also achieves large flame combustion through the connected large flame outlet 104.

[0047] The size and number of gas vents 52 determine the gas flow rate and combustion intensity; it allows for smooth switching between low and high heat and precise heat adjustment. The well-designed layout and parameter settings of the gas vents 52 ensure complete and stable gas combustion, improve combustion efficiency, reduce harmful gas emissions, and meet the heat requirements of different cooking methods.

[0048] Specifically, the gear block 8 is provided with an arc-shaped groove 82, which abuts against the micro switch 20.

[0049] The arc-shaped groove 82 on the gear shift block 8 contacts or separates from the micro switch 20 during rotation. When the arc-shaped groove 82 contacts the micro switch 20, it triggers the micro switch 20 to close or open the circuit. For example, during ignition, the rotation of the gear shift block 8 causes the arc-shaped groove 82 to trigger the micro switch 20, which closes to connect the ignition circuit, thus achieving ignition.

[0050] During the adjustment of firepower, the state change of the micro switch 20 can be fed back to the control system to control the opening and closing of the solenoid valve 7 or adjust the working state of other components.

[0051] The combination of the gear shift block 8 and the micro switch 20 achieves a close integration of mechanical operation and circuit control. Through simple changes in the mechanical structure, the circuit signal is converted, ensuring the synchronization and accuracy of gas valve operation and control. This design enhances the intelligence of the gas valve, improves safety and convenience of use, and reduces the risks associated with human error.

[0052] Specifically, the bottom of the gas chamber 105 is provided with a chamber cover 11, and a sealing ring 10 is provided between the chamber cover 11 and the gas chamber 105. The chamber cover 11 is connected to the valve body 1 by two screws 12. The sealing ring 10 prevents gas from leaking from the bottom of the gas chamber 105; opening the chamber cover 11 allows for inspection of the inside of the chamber.

[0053] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
