[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] This embodiment of an energy-saving device for a stove relates to the field of fuel stove technology. A magnetic induction switch is installed on the stove. When the iron pot leaves the stove chamber and comes into contact with the stove, the magnetic induction switch senses the iron pot and cuts off the fuel supply to prevent the fuel in the stove chamber from continuing to burn and causing fuel waste, thereby achieving the purpose of energy saving.

[0029] Please see Figures 1 to 5 This embodiment of an energy-saving device for a stove includes a magnetic attraction control component 100 and a connecting base 200. The magnetic attraction control component 100 can sense the approach of a ferromagnetic object and cut off the fuel supply. The connecting base 200 can fix the magnetic attraction control component 100 to the stovetop to ensure the normal operation of the magnetic attraction control component 100.

[0030] The magnetic control assembly 100 includes a valve 110 and a magnetic switch unit 120. The valve 110 is installed on the fuel supply pipe of the stove and can control the on / off supply of fuel. The magnetic switch unit 120 is electrically connected to the valve 110. When the magnetic switch unit 120 senses the approach of a ferromagnetic object, it can close the valve 110, cutting off the fuel supply to the stove, thus temporarily shutting off the stove and preventing the fuel in the combustion chamber from continuing to burn, which would waste fuel and achieve energy saving.

[0031] The connector 200 is detachably connected to the cooktop, allowing it to be installed on existing cooktops as needed, thus expanding its application range. The connector 200 is made of non-ferromagnetic material, ensuring it does not interfere with the operation of the magnetic switch unit 120 and guaranteeing its operational stability. The magnetic switch unit 120 is encapsulated within the connector 200, which protects the magnetic switch from external high temperature, high humidity, and oily environments.

[0032] In some embodiments, please refer to Figure 2 and Figure 3 The magnetic switch unit 120 includes a lever arm 121, a magnetic head 122, and an electrical contact switch 123. The middle part of the lever arm 121 is rotatably connected to the connecting seat 200 via a bracket. The magnetic head 122 and the electrical contact switch 123 are respectively connected to both ends of the lever arm 121. The electrical contact switch 123 is electrically connected to the valve 110. When the magnetic head 122 senses a ferromagnetic object (such as a pot) approaching, it can precisely trigger the electrical contact switch 123 through the rotation of the lever arm 121. The opening or closing of the contact switch directly controls the fuel valve 110 of the stove, thereby cutting off or opening the fuel supply. The magnetic switch unit 120 can improve the accuracy of fuel supply control. The lever arm 121 can ensure that the electrical contact switch 123 is only cut off when a pot approaches, based on the sensing sensitivity of the magnetic head 122, thus avoiding misoperation.

[0033] The magnetic switch unit 120 automates the stove fuel control without manual intervention. The sensing action of the magnetic head 122, in conjunction with the rotation of the lever arm 121, can automatically open and close the fuel valve 110 based on the proximity of the cookware, reducing energy waste caused by human negligence or operational errors.

[0034] The lever arm 121 is rotatably connected to the connecting seat 200 via a bracket, and can withstand a certain physical force without failure or jamming, ensuring the stable operation of the switching system.

[0035] In some embodiments, please continue reading Figure 2 and Figure 3 The magnetic switch unit 120 also includes a guide cylinder 124, which is fixedly connected to the connecting seat 200. The magnetic head 122 is movably inserted into the guide cylinder 124. The guide cylinder 124 provides a clear path or guide track, allowing the magnetic head 122 to move smoothly within a certain track. When a ferromagnetic object such as a pot approaches, the magnetic head 122 can be precisely guided to a predetermined position through the guide cylinder 124, which can relatively reduce the possible deviation or jamming of the magnetic head 122 during operation and ensure precise control of the system.

[0036] Meanwhile, with the help of the guide tube 124, the range of motion of the magnetic head 122 is limited, avoiding interference between the magnetic head 122 and other parts, ensuring that it can stably sense the pot and trigger the operation of the electrical contact switch 123.

[0037] The guide cylinder 124 not only provides a precise motion trajectory, but also protects the magnetic head 122 from direct impact or excessive wear from external forces, extending the service life of the magnetic head 122.

[0038] It should be noted that the guide cylinder 124 is made of copper. Copper guide cylinder 124 is a non-ferromagnetic material and cannot generate magnetic interaction with the magnetic head 122, thus interfering with the movement of the magnetic head 122.

[0039] In another implementation, the magnetic switch unit 120 can also be a spring-loaded magnetic structure. One end of the magnetic head 122 is connected by a spring, and the other end of the magnetic head 122 acts as a conductor, connecting two contacts to control the on / off state of the external circuit connected to the valve 110. When the iron pot approaches, the magnetic head 122 can be attracted, thus separating from the two contacts and controlling the valve 110 to cut off the fuel supply. When the iron pot moves away, the magnetic head 122 moves under the action of the spring, re-engaging with the contacts and controlling the valve 110 to restore the fuel supply.

[0040] It should be noted that valve 110 and igniter are interconnected. When valve 110 is opened, the igniter is activated to ignite the fuel and prevent fuel leakage.

[0041] In some embodiments, the ferromagnetic object is an iron pot. When the user removes the food from the pot, the iron pot rests on the connecting base 200 away from the stove. The magnetic switch unit 120 can be triggered by the iron pot to cut off the fuel supply to the stove, preventing the fuel in the stove from continuing to burn and wasting fuel. The top of the connecting base 200 is provided with an arc-shaped plate 222, which can cooperate with the edge of the iron pot to limit the iron pot and prevent it from moving when the food is removed from the pot, thus interfering with the user's operation.

[0042] In some embodiments, please refer to Figure 4 and Figure 5An energy-saving device for a stove also includes a manual switch assembly 300. The manual switch assembly 300 includes a pull rod 310 and an armature 320 arranged parallel to the connecting base 200. The pull rod 310 is slidably connected to the connecting base 200 via a bracket. The armature 320 is fixedly connected to the middle of the pull rod 310. The armature 320 can move relatively closer to or further away from the magnetic head 122. By introducing the manual switch assembly 300, the user can manually control the movement of the armature 320 via the pull rod 310 as needed, thereby adjusting its distance from the magnetic head 122 and controlling the opening and closing of the electrical contact switch 123. In this way, in addition to automatic magnetic control, the user can also manually intervene in specific situations, conveniently and flexibly adjusting the system.

[0043] In certain special circumstances (e.g., when the magnetic head 122 fails to detect the cookware properly, or when the energy-saving function needs to be turned off during specific periods), the manual switch provides a supplementary control method to ensure the adaptability of the system.

[0044] Adding manual control to energy-saving devices can be seen as a redundant supplement to automatic systems, improving the reliability and safety of the system under extreme conditions and avoiding single points of failure that may result from complete reliance on automatic systems.

[0045] As a further implementation, one end of the pull rod 310 is provided with a curved handle 311. The curved handle 311 makes the pull rod 310 more ergonomic and more comfortable to operate. Users can more naturally grasp the curved handle 311 to pull, reducing the need for force and avoiding the discomfort caused by directly pulling a straight rod.

[0046] The other end of the pull rod 310 is equipped with a relatively enlarged anti-slip head 312, and the curved handle 311 provides a larger gripping space, allowing fingers to grip the handle more firmly. This is especially beneficial in high-temperature environments like kitchens, providing a more stable and comfortable grip and preventing slippage or instability during operation. The enlarged anti-slip head 312 effectively prevents the pull rod 310 from detaching from the connecting seat 200 or other components. During operation, especially when the pull rod 310 is under force, the anti-slip head 312 provides a physical barrier, ensuring that the pull rod 310 remains in the predetermined position and does not detach due to external forces. This contributes to improving the stability and reliability of the entire device.

[0047] In some embodiments, please refer to Figure 2 The connector 200 includes an L-shaped clamp 210 that mates with the cooktop body and a casing 220. The L-shaped clamp 210 fits tightly with the outer side of the cooktop body, making the connection between the connector 200 and the cooktop body more secure. The L-shaped clamp 210 typically provides stronger shear resistance, ensuring that the connector 200 will not loosen or shift due to vibration or external forces during use, thus increasing the overall stability of the system.

[0048] The encapsulation box 220 is fixedly connected to the L-shaped clamp 210, which enhances the overall structure and makes the connector 200 not only stable but also more compact, avoiding damage or misoperation caused by loose connection.

[0049] The L-shaped clamp 210 has multiple mounting holes 211, which provide more fixing points, allowing the connector 200 to be adjusted and fixed in different positions. The mounting holes 211 not only improve the flexibility of installation, but also better adapt to the shape and size of different stove bodies, ensuring that the connector 200 can be installed stably in various environments.

[0050] In practice, screws can pass through mounting holes 211 to connect with the stove, thus fixing and connecting the L-shaped clamp 210 to the stove.

[0051] Workflow: Fix the L-shaped clamp 210 to the stovetop and install the valve 110 on the stove's fuel supply pipe. The magnetic switch unit 120 in the enclosure 220 is electrically connected to the valve 110 via a wire. When the user removes the food from the pot, simply place the pot on the enclosure 220; the magnetic switch unit 120 is triggered by the pot, controlling the valve 110 to cut off the fuel supply and extinguish the flame.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
