Description

Technical Field

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

[0002] In modern kitchens, gas ovens, as novel cooking appliances, directly impact user experience and quality of life through their performance and safety. The switch and valve seat structure, as core components of a gas oven, plays a crucial role in precisely controlling ignition timing and electronic linkages throughout the oven's operation.

[0003] Existing gas oven valve designs still have significant shortcomings. To achieve the two core control functions of ignition and electronic linkage, traditional valve bodies often rely on multiple independent components working together. From the valve core and sealing ring to the adjusting rod, micro-switch components, and linkage levers, the complex composition of these parts makes the valve body structure bulky and redundant. This "multi-component stacking" design not only results in a large valve body with low space utilization, making it difficult to adapt to the trend of modern kitchen equipment towards thinner and more integrated designs, but also increases the difficulty of material management and assembly complexity in the manufacturing process, significantly increasing production costs. More importantly, during long-term use, wear or failure of any component can cause functional disorders in the entire valve system, increasing the difficulty and cost of later maintenance, which falls short of users' expectations for efficient, convenient, and reliable kitchen equipment. Utility Model Content

[0004] This utility model provides a switch and valve seat structure to solve the problems in the prior art.

[0005] The present invention adopts the following technical solution: a switch and valve seat structure, including a valve body, a valve seat, a rotating shaft, a switch pressing block, a retaining ring, a push rod pressing block, and a limiting block. The valve seat is installed on the valve body by screws. Microswitches one, two, and three are installed on the valve seat by several screws. The rotating shaft is rotatably connected to the valve seat and can move downward along the valve seat. The retaining ring is engaged with the rotating shaft. The switch pressing block is sleeved above the rotating shaft by the retaining ring. The push rod pressing block and the limiting block are sleeved below the rotating shaft and inserted into the valve body.

[0006] Furthermore, the switch pressure block is provided with two arc-shaped rotating ends arranged vertically.

[0007] Furthermore, the trigger end of the first micro switch is located between the switch rotating block and the valve seat, and the trigger ends of the second and third micro switches are respectively in contact with the two arc-shaped rotating ends.

[0008] Furthermore, the push rod pressure block extends to the outside of the valve seat, and the valve body is provided with a moving groove for the push rod pressure block to move downward.

[0009] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0010] This invention cleverly arranges three switches and a switch rotating block, abandoning the traditional valve body model that relies on multiple independent components working together, thus greatly simplifying the structural composition. Compared to the traditional bulky and redundant valve body design, this structure effectively reduces the volume, improves space utilization, and better adapts to the development trend of modern kitchen equipment towards thinner and more integrated designs, facilitating reasonable layout within the limited internal space of the oven.

[0018] 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.

[0019] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1 to 4 As shown, this utility model embodiment provides a switch and valve seat structure, including a valve body 1, a valve seat 2, a rotating shaft 3, a switch pressing block 4, a retaining ring 5, a push rod pressing block 6, and a limiting block 7. The valve seat 2 is mounted on the valve body 1 by screws. Microswitches 8, 9, and 10 are mounted on the valve seat 2 by several screws. The rotating shaft 3 is rotatably connected to the valve seat 2 and can move downward along the valve seat 2. The retaining ring 5 is engaged with the rotating shaft 3. The switch pressing block 4 is sleeved above the rotating shaft 3 by the retaining ring 5. The push rod pressing block 6 and the limiting block 7 are sleeved below the rotating shaft 3 and inserted into the valve body 1.

[0021] Working principle: When the gas oven needs to be operated, an external force is applied to the rotating shaft 3. If the rotating shaft 3 is pressed down, it moves downward within the valve seat 2. Since the switch pressing block 4 is sleeved above the rotating shaft 3 via the retaining spring 5, it moves downward synchronously with the rotating shaft 3, thereby contacting the micro switch 8 located between the switch pressing block 4 and the valve seat 2, realizing the ignition start function. When the rotating shaft 3 is rotated, it drives the switch pressing block 4 to rotate. The two arc-shaped rotating ends 11 on the switch pressing block 4 contact the trigger ends of the micro switch 9 and the micro switch 10, respectively, thereby realizing the electronic control linkage of other functions. The push rod pressing block 6 is sleeved below the rotating shaft 3 and extends to the outside of the valve seat 2. When the rotating shaft 3 moves, the push rod pressing block 6 can move up and down within the moving groove 12 of the valve body 1, which helps to stabilize the movement of the rotating shaft 3 and transmit force. The limit block 7 restricts the excessive downward movement of the rotating shaft 3, ensuring the stability and safety of the entire structure.

[0022] This switch and valve seat structure cleverly arranges three switches and a switch rotating block, abandoning the traditional valve body 1 model that relies on multiple independent components working together, greatly simplifying the structural composition. Compared to the traditional bulky and redundant valve body 1 design, this structure effectively reduces the volume, improves space utilization, and better adapts to the development trend of modern kitchen equipment towards thinner and more integrated designs, facilitating reasonable layout within the limited internal space of the oven.

[0023] Specifically, the switch pressure block 4 is provided with two arc-shaped rotating ends 11 arranged vertically; the trigger end of the micro switch 8 is located between the switch pressure block 4 and the valve seat 2, and the trigger ends of the micro switch 9 and the micro switch 3 are respectively in contact with the two arc-shaped rotating ends 11.

[0024] The switch pressure block 4 has two arc-shaped rotating ends 11 positioned vertically, which play a crucial role in the rotation of the rotating shaft 3. As the rotating shaft 3 rotates, the positions of the two arc-shaped rotating ends 11 change, and the degree of contact with the trigger ends of microswitches 9 and 10 also changes accordingly. By precisely designing the curvature and position of the arc-shaped rotating ends 11, different degrees of triggering of microswitches 9 and 10 can be achieved, thereby accurately controlling the firepower and realizing firepower adjustment at different levels, while reliably triggering the flameout protection mechanism.

[0025] Specifically, the push rod pressure block 6 extends to the outside of the valve seat 2, and the valve body 1 is provided with a moving groove 12 for the push rod pressure block 6 to move downward.

[0026] During the downward or rotational process of the rotating shaft 3, the push rod pressure block 6 moves within the movable groove 12 of the valve body 1. When the rotating shaft 3 is pressed down, the push rod pressure block 6 moves downward within the movable groove 12, providing stable support and guidance for the downward action of the rotating shaft 3 and preventing the rotating shaft 3 from deviating. When the rotating shaft 3 rotates, the push rod pressure block 6 also moves accordingly within the movable groove 12, ensuring the stability of the rotating shaft 3 during rotation and enabling the switch pressure block 4 to accurately contact each microswitch, ensuring the normal operation of all functions of the gas oven.

[0027] 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.
