Description

Technical Field

[0001] This utility model belongs to the field of gas stove technology, and in particular relates to a manual stop valve with gear positions and a switch function. Background Technology

[0002] Adjusting the flame intensity of a gas stove is a key concern for users. Traditional stopcock valves adjust the flame intensity by turning a knob, but they have no limit on the rotation angle and are easily affected by accident, making it impossible to precisely control the heat. This cannot meet the precise heat control requirements of users in different cooking scenarios such as stir-frying and simmering soup. Therefore, there is a need for stopcock valves with adjustable settings to achieve precise adjustment of different heat levels.

[0003] However, existing stopcock valves with position settings generally suffer from structural design flaws: in addition to the positioner, an independent microswitch is required to achieve the opening and closing function, resulting in a complex product structure and cumbersome manufacturing processes. This design not only increases the difficulty of assembling parts, but also further increases material costs and production time due to the difficulty of achieving one-piece molding of multiple components, revealing significant economic shortcomings in large-scale applications.

Detailed Implementation

[0023] 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.

[0024] The following detailed description, in conjunction with the accompanying drawings, illustrates the technical solution of a manual plug valve with gear positions and switching function provided by various embodiments of the present invention.

[0025] Reference Figures 1 to 5 As shown, this utility model embodiment provides a manual plug valve with a gear position and switching function, including a valve body 1, a valve core 2, a valve seat 3, a gear positioner seat 4, a gear positioner block 5, a fixed housing switch piece 6, a switch piece 7, a connecting spring 8, a rotating shaft 9, and a connecting plate 10. The connecting plate 10 is located at the bottom of the valve seat 3. The valve seat 3 and the connecting plate 10 are connected to the valve body 1 by two screws 16. The rotating shaft 9 passes sequentially through the valve seat 3, the connecting spring 8, the switch piece 7, the fixed housing switch piece 6, the gear positioner block 5, the gear positioner seat 4, and the connecting plate 10, extending to the valve body. Inside the valve core 2, the valve core 2 is located at the bottom of the rotating shaft 9. The gear block 5 is connected to the gear positioner seat 4 via a fixed housing switch piece 6. The gear block 5 rotates within the gear positioner seat 4 and the fixed housing switch piece 6 via the rotating shaft 9. The gear positioner seat 4 is provided with a positioning element for positioning the gear block 5. The rotating shaft 9 is provided with a flat part 92, and the gear block 5 is provided with a snap-fit ​​groove 52 that engages with the flat part 92, so that the rotating shaft 9 and the gear block 5 rotate synchronously. The valve core 2 is provided with several air outlets 22 for adjusting fluid flow or balancing internal pressure.

[0026] Working principle: When the user manually rotates the shaft 9, the shaft 9 engages with the locking groove 52 of the gear block 5 through the flat part 92, driving the gear block 5 to rotate. Since the different grooves 51 of the gear block 5 correspond to different rotation angles of the shaft 9, and the lever 91 of the shaft 9 matches the groove of the valve core 2, the rotation angle of the valve core 2 also corresponds to the groove 51 of the gear block 5, thereby achieving a precise match of the fixed angle relationship between the three components: the gear block 5, the shaft 9, and the valve core 2. Under this correspondence, the gas outlet 22 of the valve core 2 corresponds one-to-one with the gas outlet channel of the valve body 1. By controlling the rotation position of the gas outlet 22, a unique gas flow rate is achieved for each gear, thereby outputting different gas power and achieving the purpose of different power for different gears.

[0027] This invention integrates gas level adjustment and on / off functions into one unit. Compared to the complex structure of traditional plug valves that require a separate microswitch, it simplifies the number of parts and assembly process, reducing processing difficulty and production costs. Simultaneously, the precise coordination between components ensures the stability and accuracy of gas flow control, meeting users' needs for different gas stove power levels. Furthermore, the integrated design makes the product structure more compact, occupies less space, and is suitable for the installation needs of various gas stoves.

[0028] Specifically, the positioning component includes a positioning spring 11 and a positioning ball 12. The gear positioner seat 4 is provided with a mounting groove 41. The positioning spring 11 is disposed in the mounting groove 41. The positioning ball 12 is connected to the positioning spring 11. The gear position block 5 is provided with a plurality of grooves 51 that cooperate with the positioning ball 12 to realize multi-gear positioning.

[0029] When the rotating shaft 9 drives the gear block 5 to rotate, the positioning ball 12 can switch between different grooves 51 of the gear block 5 under the elastic force of the positioning spring 11. When the positioning ball 12 falls into a certain groove 51, it will produce obvious damping sensation, providing the user with clear gear feedback. At this time, the valve core 2 is at the corresponding fixed angle, and the corresponding gas passage is connected to the gas outlet passage of the valve body 1 to realize the gas flow output of that gear. In this way, the user can clearly perceive the gear switching and avoid inaccurate firepower adjustment due to misoperation.

[0030] Specifically, the bottom of the rotating shaft 9 is provided with a lever 91, and the valve core 2 is provided with a sliding groove 21 that slides with the lever 91; so that when the rotating shaft 9 rotates, it can drive the valve core 2 to rotate synchronously, and at the same time allow the valve core 2 to move axially along the rotating shaft 9; the bottom of the rotating shaft 9 is provided with a valve needle 13, which is used to control the fluid on / off or flow rate adjustment; the valve core 2 is provided with a mounting plate 14 inside, and the valve needle 13 is slidably connected to the mounting plate 14; a return spring 15 is provided between the mounting plate 14 and the rotating shaft 9, and the return spring 15 is sleeved on the valve needle 13 to provide axial return force for the valve needle 13.

[0031] When the rotating shaft 9 rotates, the lever 91 slides within the groove 21, thereby causing the valve core 2 to rotate synchronously. Simultaneously, the valve needle 13 at the bottom of the rotating shaft 9 is slidably connected to the mounting plate 14 inside the valve core 2. A return spring 15 is provided between the mounting plate 14 and the rotating shaft 9, and the return spring 15 is sleeved on the valve needle 13. When the stopcock is pressed down to open, the rotating shaft 9 presses down, and the valve needle 13 moves downward accordingly, opening the ignition path. After the rotating shaft 9 is released, under the elastic force of the return spring 15, the rotating shaft 9 and the valve needle 13 return to their original positions, the ignition path is disconnected, and ignition stops. During this process, the cooperation between the lever 91 and the groove 21 ensures the consistency of the rotation angle of the valve core 2 with that of the rotating shaft 9, guaranteeing the accurate correspondence between the gas passage and the gear position.

[0032] Specifically, the fixed housing switch piece 6 is connected to the gear positioner seat 4 by riveting or snap-fitting.

[0033] This connection method allows the fixed housing switch piece 6 to be securely mounted on the gear positioner seat 4. When the stopcock is pressed down to open, the rotating shaft 9 presses down, causing the switch piece 7 to move downwards and contact the fixed housing switch piece 6, connecting to the positive terminal of the power supply of the fixed housing switch piece 6. Through short-circuiting, the ignition switch function is realized. Because of the secure connection method, the relative position between the fixed housing switch piece 6 and the gear positioner seat 4 remains stable during multiple operations, and the normal functioning of the ignition switch will not be affected.

[0034] Specifically, the switch piece 7 is lower than the periphery of the gear positioner seat 4 and is insulated from the valve seat 3 after assembly.

[0035] 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.
