Description

Technical Field

[0001] This utility model belongs to the field of gas valve technology, and in particular relates to a gas valve body structure. Background Technology

[0002] A gas stove is a kitchen appliance that uses liquefied petroleum gas (LPG), manufactured gas, natural gas, or other gaseous fuels for direct-fire heating. Gas stoves are also called gas cooktops, stove plates, cooktops, or cooking appliances; their widespread use is well-known, yet a universally accepted definition is difficult to find. Based on the gas source, gas stoves are mainly divided into LPG stoves, manufactured gas stoves, and natural gas stoves. Based on the number of burners, they are divided into single-burner, double-burner, and multi-burner stoves.

[0003] In existing valve body structures, the components used to open the solenoid valve during valve opening are mostly designed using sheet metal parts. However, due to the limitations of sheet metal processing technology, this component is prone to deformation during the forming process, and its dimensional tolerances are relatively large. This results in insufficient assembly accuracy and reduced functional stability, seriously affecting the overall performance and service life of the product.

[0004] Based on this, the present invention aims to propose an innovative structural design to effectively solve the above-mentioned technical pain points. Utility Model Content

[0006] The present invention adopts the following technical solution: a gas valve body structure, including a valve body, a valve seat, a rotating shaft assembly, a connecting plate, a push rod, a push rod pressure block, a solenoid valve, a spring, and a limiting block. The connecting plate is mounted on the valve body, the valve seat is mounted on the connecting plate while fitted with the rotating shaft assembly, the connecting plate is provided with a micro switch one and a micro switch two, the push rod pressure block is fitted on the rotating shaft assembly and located below the connecting plate, the limiting block is located below the push rod pressure block, the bottom of the rotating shaft assembly is connected to a valve core, the spring is connected between the limiting block and the valve core, the solenoid valve is mounted on the valve body, the push rod pressure block is attached to the head of the push rod, and the tail of the push rod is attached to the solenoid valve.

[0007] Furthermore, the trigger ends of micro switch one and micro switch two are in contact with the rotating shaft assembly.

[0008] Furthermore, the push rod pressure block can slide axially, and the valve body is provided with a moving groove for the push rod pressure block to move.

[0009] Furthermore, the rotating shaft assembly and the solenoid valve are in the same horizontal direction.

[0010] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0011] In this invention, when the user presses down on the rotating shaft assembly, the push rod pressure block moves downward, pushing the push rod down, which in turn opens the solenoid valve, thus opening the gas passage. Simultaneously, the downward pressure triggers microswitch two, outputting a specific functional signal. When the user rotates the rotating shaft assembly, it triggers microswitch one, outputting another functional signal. Throughout the process, the components cooperate, using mechanical transmission and signal triggering to achieve gas on / off control and function switching. This invention integrates gas on / off control, solenoid valve opening, and microswitch triggering functions into one unit. Compared to the traditional sheet metal solenoid valve structure, it avoids the problems of easy deformation and large errors in sheet metal parts, improving structural stability and control accuracy. The integrated design simplifies the assembly process, reduces the number of parts, and lowers production difficulty and cost. Attached Figure Description

[0019] 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.

[0020] The technical solution of a gas valve body structure provided by various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1 to 4 As shown, this utility model embodiment provides a gas valve body structure, including a valve body 1, a valve seat 2, a rotating shaft assembly 3, a connecting plate 4, a push rod 5, a push rod pressure block 6, a solenoid valve 7, a spring 8, and a limiting block 9. The connecting plate 4 is mounted on the valve body 1, and the valve seat 2 is fitted onto the rotating shaft assembly 3 and mounted on the connecting plate 4. The connecting plate 4 is provided with a micro switch 10 and a micro switch 11. The push rod pressure block 6 is fitted onto the rotating shaft assembly 3 and located below the connecting plate 4. The limiting block 9 is located below the push rod pressure block 6. A valve core 12 is connected to the bottom of the rotating shaft assembly 3. Rotating the rotating shaft assembly 3 can drive the valve core 12 to rotate to control the gas flow. The spring 8 is connected between the limiting block 9 and the valve core 12 to provide the reset force of the valve core 12. The solenoid valve 7 is mounted on the valve body 1. The push rod pressure block 6 is attached to the head of the push rod 5, and the tail of the push rod 5 is attached to the solenoid valve 7.

[0022] Working Principle: When the user presses down on the rotating shaft assembly 3, the push rod block 6 moves downward, pushing the push rod 5 down. The push rod 5 then opens the solenoid valve 7, opening the gas passage. Simultaneously, the pressing action triggers micro switch 11, outputting a specific function signal. When the user rotates the rotating shaft assembly 3, it triggers micro switch 10, outputting another function signal. Throughout the process, the components cooperate with each other, using mechanical transmission and signal triggering to achieve gas on / off control and function switching. This invention integrates gas on / off control, solenoid valve 7 opening, and micro switch triggering functions into one unit. Compared to the traditional sheet metal part structure that opens the solenoid valve 7, it avoids the problems of easy deformation and large errors of sheet metal parts, improving structural stability and control accuracy. The integrated design simplifies the assembly process, reduces the number of parts, and lowers the difficulty and cost of production and processing.

[0023] Specifically, the trigger ends of the micro switch 10 and the micro switch 21 are in contact with the rotating shaft assembly 3.

[0024] The trigger ends of microswitches 10 and 11 are in direct contact with the rotating shaft assembly 3. This design establishes a direct link between mechanical action and electrical signal output. When the user presses down on the rotating shaft assembly 3, the downward displacement of the assembly directly acts on the trigger end of microswitch 11, causing the internal contacts of microswitch 11 to close or open, thereby generating a corresponding electrical signal. This signal can be used to control functions such as starting the ignition device and regulating gas flow. When the user rotates the rotating shaft assembly 3, the rotation causes it to contact the trigger end of microswitch 10 and generate displacement, triggering microswitch 10 to output another electrical signal for different functional controls, such as switching the gas stove's firepower mode. In this way, the user's operation can be quickly and accurately converted into electrical signals, realizing intelligent control of the gas equipment.

[0025] The direct contact triggering method between the microswitch and the rotating shaft assembly 3 ensures the timeliness and accuracy of signal triggering. Compared to indirect triggering structures, this reduces delays and errors in signal transmission, enabling rapid response to operation commands and improving the user experience.

[0026] Specifically, the push rod pressure block 6 can slide axially, and the valve body 1 is provided with a moving groove 13 for the push rod pressure block 6 to move.

[0027] The movable groove 13 provides precise guidance and limiting space for the movement of the push rod pressure block 6. When the rotating shaft assembly 3 is pressed down, the push rod pressure block 6 moves steadily downward in the vertical direction within the movable groove 13, preventing the push rod pressure block 6 from shifting or shaking during movement. Due to the limiting effect of the movable groove 13, the push rod pressure block 6 can accurately transmit pressure to the push rod 5, causing the push rod 5 to press down in a predetermined direction to open the solenoid valve 7.

[0028] Specifically, the rotating shaft assembly 3 and the solenoid valve 7 are arranged in the same horizontal direction. This horizontal arrangement forms a unique horizontal transmission structure. When the rotating shaft assembly 3 is pressed down, the force transmission is direct and smooth. The push rod pressure block 6 can quickly and accurately transmit the downward pressure of the rotating shaft assembly 3 to the push rod 5, thereby opening the solenoid valve 7. This horizontal layout avoids energy loss and transmission errors caused by changes in the force transmission angle, allowing the push rod pressure block 6 to open the solenoid valve 7 with minimal force loss, thus improving energy utilization efficiency. Simultaneously, the horizontal layout simplifies the structural hierarchy, making the connections between components more compact and reducing unnecessary intermediate transmission parts.

[0029] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
