Abstract
Description
Technical Field
[0001] This application relates to the field of stove switch detection technology, and in particular to a gas stove switch detection device. Background Technology
[0002] Currently, most gas stoves on the market still have significant safety hazards, especially in monitoring the on / off status. Traditional gas stoves mostly rely on users manually turning off the valve to stop the gas supply, which is prone to accidents if the valve is forgotten to be turned off. With the popularization of smart home concepts and technological advancements, more and more smart functions are being integrated into gas stoves, such as automatic flameout protection and temperature sensing.
[0003] Currently, there are several technical solutions available for detecting the on / off status of gas stoves. One common method is to install a limit switch on the gas valve, using physical contact to determine whether the valve is open. Another method uses a Hall effect sensor to detect changes in the position of a magnet, thus indirectly reflecting the valve's status. However, both methods have significant limitations. The former suffers from wear and tear over time, affecting detection accuracy, while the latter is susceptible to interference from external magnetic fields, leading to misjudgments. In addition, more advanced technologies, such as infrared detection and image recognition, are also being applied to some high-end models.
[0004] Existing technologies for detecting the valve status of gas stoves generally suffer from low reliability and susceptibility to interference from external factors. In particular, they often fail to achieve the expected level of safety assurance in the complex and ever-changing home environment. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a gas stove switch detection device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.
[0006] To achieve the above objectives, this application adopts the following technical solution: a gas stove switch detection device, comprising a stove body, a connecting pipe fixedly connected to the bottom of the stove body, a valve fixedly connected to the end of the connecting pipe away from the connecting pipe, a connecting pipe fixedly connected to the side of the valve away from the connecting pipe, a handle rotatably mounted on the top of the valve, an insertion hole opened on the top of the handle, an insertion plate inserted into the inner wall of the insertion hole, a light shield fixedly mounted on the top of the insertion plate, a positioning plate fixedly mounted on the top of the valve, a light emitter and a light receiver symmetrically mounted on the top of the positioning plate, a protective cover fixedly mounted on the outer side of the handle, a rod slidably connected to the inner wall of the protective cover, a disc fixedly mounted on the outer edge of the rod, and a spring fixedly connected to the outer side of the disc.
[0007] In a preferred embodiment, a signal processor is fixedly installed at the bottom of the stove body, and the light shield is located between the light emitter and the light receiver, and the light receiver and the signal processor are electrically connected.
[0008] By adopting the above technical solution, when the handle is rotated to the closed position, the light shield is exactly above the light path, blocking the transmission of light. At this time, the light receiver fails to receive the light signal, triggering the internal circuit to generate a corresponding electrical signal, which is then processed by the signal processor and output to the control system, thereby realizing precise monitoring of the valve opening and closing status.
[0009] In a preferred embodiment, the end of the spring away from the disc is fixedly connected to an abutment plate, and the insertion rod is slidably connected to the inner wall of the protective cover.
[0010] By adopting the above technical solution, the end of the spring away from the disk can be limited, thereby ensuring that the spring will not rub against the inner wall of the protective cover under stress, thus ensuring the stability of the spring under stress and when returning to its original position.
[0011] In a preferred embodiment, a support rod is fixedly connected to the bottom of the valve, and the bottom of the support rod is fixedly connected to the kitchen cabinet.
[0012] By adopting the above technical solution, the support rod can be used to support and position the valve, thus ensuring the stability of the valve.
[0013] In a preferred embodiment, the insert plate is adapted to be inserted into the inner wall of the socket, the inner wall of the insert plate has a circular hole, and the end of the insert rod near the handle is slidably connected to the inner wall of the handle and inserted into the inner wall of the circular hole.
[0014] By adopting the above technical solution, the insert plate can be stably positioned on the inner wall of the socket using the insert rod, ensuring stability after positioning, and the light shield can be stably installed on the top of the handle.
[0015] In a preferred embodiment, a pull plate is fixedly installed at the end of the insertion rod away from the handle.
[0016] By adopting the above technical solution, the user's convenience in pulling the plug bar is increased, making it easier to move the end of the plug bar away from the inner wall of the plug plate, thereby enabling the disassembly of the light shield and the plug plate, and also making it easier to remove the light shield for disassembly.
[0017] In a preferred embodiment, four pads are symmetrically fixedly installed at the bottom of the stove body, and all four pads are made of rubber.
[0018] By adopting the above technical solution, the stove body can be placed stably on the countertop, increasing the friction between it and the countertop, ensuring stability after placement, and preventing easy displacement during use.
[0019] The beneficial effects of this application are:
[0020] 1. This gas stove switch detection device, by setting up a light shield, a light emitter, a light receiver, and a signal processor, ensures that when the valve is open, the light shield leaves the light path area, the light emitted by the light emitter reaches the light receiver smoothly, and the signal processor receives a stable light signal and remains silent. Conversely, when the valve is closed, the light shield enters the light path area and blocks the light propagation, causing the light receiver to be unable to receive a light signal of sufficient intensity, thereby triggering the signal processor to send an alarm command to the control system, notifying the user to check the working status of the stove in time, reducing the safety hazards of the stove and improving the user's sense of security.
[0021] 2. This gas stove switch detection device moves the plug rod by pulling the pull plate until the end of the plug rod away from the pull plate is separated from the inner wall of the plug plate. Then the plug plate can be removed from the inner wall of the socket, thereby realizing the disassembly of the light shield. This makes it easy to wipe and clean the light shield. The structure is compact and reasonable, easy to install and maintain, and greatly facilitates daily use. Attached Figure Description

Detailed Implementation
[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0029] Reference Figure 1-5 A gas stove switch detection device includes a stove body 1. A connecting pipe 2 is fixedly connected to the bottom of the stove body 1. A valve 3 is fixedly connected to the end of the connecting pipe 2 away from the connecting pipe 2. A connecting pipe 4 is fixedly connected to the side of the valve 3 away from the connecting pipe 2. A handle 6 is rotatably installed on the top of the valve 3. An insertion hole 7 is opened on the top of the handle 6. An insertion plate 8 is inserted into the inner wall of the insertion hole 7. A light shield 9 is fixedly installed on the top of the insertion plate 8. A positioning plate 12 is fixedly installed on the top of the valve 3. A light emitter 10 and a light receiver 11 are symmetrically installed on the top of the positioning plate 12. A protective cover 13 is fixedly installed on the outer side of the handle 6. An insertion rod 14 is slidably connected to the inner wall of the protective cover 13. A disc 15 is fixedly installed on the outer edge of the insertion rod 14. A spring 16 is fixedly connected to the outer side of the disc 15.
[0030] See Figure 2 and Figure 3 A signal processor 19 is fixedly installed at the bottom of the stove body 1. A light shield 9 is positioned between the light emitter 10 and the light receiver 11. The light receiver 11 and the signal processor 19 are electrically connected so that when the handle 6 is rotated to the closed position, the light shield 9 is positioned directly above the light path, blocking the light transmission. At this time, the light receiver 11 fails to receive the light signal, triggering the internal circuit to generate a corresponding electrical signal, which is then processed by the signal processor 19 and output to the control system to achieve precise monitoring of the opening and closing status of the valve 3.
[0031] See Figure 5 The end of the spring 16 away from the disc 15 is fixedly connected to the abutment plate 17, and the plug rod 14 is slidably connected to the inner wall of the protective cover 13, so that the end of the spring 16 away from the disc 15 can be limited, thereby ensuring that the spring 16 under force will not rub against the inner wall of the protective cover 13, thus ensuring the stability of the spring 16 under force and when returning to its original position.
[0032] See Figure 3 A support rod 5 is fixedly connected to the bottom of valve 3. The bottom of the support rod 5 is fixedly connected to the kitchen cabinet, so that the support rod 5 can be used to support and position valve 3, ensuring the stability of valve 3.
[0033] See Figure 4 and Figure 5The insert plate 8 is adapted to be inserted into the inner wall of the socket 7. The inner wall of the insert plate 8 has a round hole. The end of the insert rod 14 near the handle 6 is slidably connected to the inner wall of the handle 6 and inserted into the inner wall of the round hole. This allows the insert plate 8 to be stably positioned on the inner wall of the socket 7 using the insert rod 14, ensuring stability after positioning. It also allows the light shield 9 to be stably installed on the top of the handle 6.
[0034] See Figure 4 A pull plate 18 is fixedly installed at the end of the insertion rod 14 away from the handle 6, which increases the convenience for the user to pull the insertion rod 14 and makes it easier to move the end of the insertion rod 14 away from the pull plate 18 away from the inner wall of the insertion plate 8, thereby enabling the disassembly of the light shield 9 and the insertion plate 8, and also making it easy to remove the light shield 9 for disassembly.
[0035] See Figure 1 and Figure 2 Four pads are symmetrically fixed at the bottom of the stove body 1. All four pads are made of rubber, which allows the stove body 1 to be placed stably on the countertop, increases the friction between it and the countertop, ensures the stability after placement, and prevents it from easily shifting during use.
[0036] Working principle: When valve 3 is opened, the light shield 9 leaves the light path area, and the light emitted by the light emitter 10 reaches the light receiver 11 smoothly. The signal processor 19 receives a stable light signal and remains silent. Conversely, when valve 3 is closed, the light shield 9 enters the light path area and blocks the light propagation, causing the light receiver 11 to be unable to receive a light signal of sufficient intensity. This triggers the signal processor 19 to send an alarm command to the control system, notifying the user to check the working status of the stove body 1 in time. At the same time, the pull plate 18 can be pulled to move the plug rod 14 until the end of the plug rod 14 away from the pull plate 18 is separated from the inner wall of the plug plate 8. Then the plug plate 8 can be removed from the inner wall of the socket 7, thereby realizing the disassembly of the light shield 9, which makes it easier to wipe and clean the light shield 9.
