Technical Field
[0001] This utility model relates to the field of gas stove technology, specifically a gas stove for preventing dry burning. Background Technology
[0002] A gas stove is a household kitchen appliance that provides cooking heat by burning gaseous fuels such as natural gas or liquefied petroleum gas. It mainly consists of core components such as the cooktop, burner, injector tube, stopcock valve, and ignition device. Its working principle is that rotating the knob releases gas, while the ignition device generates an electric spark to ignite it. The flame is then emitted through evenly distributed flame holes on the burner, directly heating the bottom of the pot. Modern gas stoves typically have important functions such as electronic pulse ignition and flameout protection devices to ensure convenient and safe use. Its biggest advantage is its rapid heat and direct heating, precisely meeting the heat requirements of Chinese stir-frying and other cooking methods. However, proper ventilation is necessary during use to prevent gas leaks.
[0003] A gas stove disclosed in Chinese Patent Publication No. CN210532473U features multiple support claws directly mounted on the cooktop panel, which improves the stability of the support claws and ensures the support capacity for cookware. At the same time, it avoids the need for a support ring for the pot support and omits the liquid collection tray, making the structure simple.
[0004] However, when changing cookware, the gas stove may burn dry, which can easily ignite surrounding items and cause a fire. It can also burn and deform the metal parts of the stove, shatter the glass panel, or even damage safety devices and cause gas leaks, posing a certain safety hazard. Utility Model Content
[0005] The purpose of this utility model is to provide a gas stove for preventing dry burning, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas stove for preventing dry burning, comprising a stove platform, a stopcock valve fixedly connected to the center of the front end of the stove platform, an igniter fixedly connected to the rear end of the stopcock valve, a gas pipe fixedly connected to the bottom of the rear end of the igniter, a gas supply pipe fixedly connected to the rear end of the gas pipe, a burner head fixedly connected to the top of the rear end of the igniter, a burner fixedly connected to the top of the rear end of the burner, a fixed base fixedly connected to the center of the bottom of the inside of the stove platform, a pressing mechanism provided at the top of the fixed base, a support frame provided at the top of the pressing mechanism, and a limiting mechanism for installing and removing the support frame.
[0007] Preferably, the pressing mechanism includes a pressure sensor fixedly connected to the center of the fixed base, slots being provided at the front and rear ends of the upper surface of the fixed base, an annular seat being fixedly connected to the top of the fixed base, an annular groove being provided inside the annular seat, a movable ring being slidably connected inside the annular groove, springs being uniformly and circumferentially fixedly connected to the bottom end of the movable ring, pressing rods being fixedly connected to the front and rear ends of the lower surface of the movable ring, and a solenoid valve being fixedly connected to the center of the gas pipe.
[0008] Preferably, the output of the pressure sensor is electrically connected to the input of the solenoid valve via a central controller, and the number of slots and pressing rods correspond to each other.
[0009] Preferably, the limiting mechanism includes a threaded ring fixed to the bottom end of the support frame, the outside of the threaded ring being inserted into a movable ring, a magnetic groove being formed at the center of the front end of the threaded ring, a movable groove being formed at the center of the front end of the movable ring, a movable block being slidably connected inside the movable groove, a magnetic block being fixed to the rear end of the movable block, a pull rope being fixed to the front end of the movable block, and a pull block being fixed to the front end of the pull rope.
[0010] Preferably, the contact surfaces of the magnetic groove and the magnetic block are magnetically attracted to each other.
[0011] Preferably, the annular seat and the support frame have a groove at the front end for the furnace head to pass through.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This type of gas stove designed to prevent dry burning features a support frame on the outside of the burner. This support frame effectively supports the pot on top of the gas stove. When the support frame senses the weight of the pot, a movable ring compresses a spring. This movable ring then moves a pressing rod into a slot on the fixed base, pressing a pressure sensor at the bottom of the slot. If the pressure sensor receives pressure exceeding a threshold, it controls the solenoid valve to open, allowing gas to be transmitted through the gas pipe. When there is no pot on top of the support frame, the reaction force of the compressed spring pushes the support frame back to its original position via the movable ring. This causes the movable ring to pull the pressing rod out of the slot on the fixed base. In this case, the pressure sensor no longer receives pressure and controls the solenoid valve to close, canceling gas delivery and preventing dry burning. This improves the overall safety and stability of the gas stove.
[0014] 2. This type of gas stove designed to prevent dry burning features a threaded ring at the bottom of the support frame. The threaded ring is inserted into a movable ring on the annular seat. The magnetic block inside the movable ring, due to magnetic force, can insert into the magnetic groove on the threaded ring, allowing for quick installation of the support frame at the top of the annular seat. When the support frame needs to be replaced for different cookware, pulling a lever on the annular seat from the bottom of the stove allows the lever to pull the magnetic block out of the magnetic groove on the threaded ring, enabling rapid replacement of the support frame. This improves the overall applicability and stability of the gas stove. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1-5 As shown, this utility model has the following two specific embodiments.
[0024] Example 1
[0025] A gas stove for preventing dry burning includes a stove platform 1. A stopcock valve 2 is fixedly connected to the center of the front end of the stove platform 1. An igniter 201 is fixedly connected to the rear end of the stopcock valve 2. A gas pipe 3 is fixedly connected to the bottom of the rear end of the igniter 201. A gas supply pipe 302 is fixedly connected to the rear end of the gas pipe 3. A burner 4 is fixedly connected to the top of the rear end of the igniter 201. A burner 5 is fixedly connected to the top of the rear end of the burner 4. A fixing seat 6 is fixedly connected to the center of the bottom of the inside of the stove platform 1. A pressing mechanism is provided at the top of the fixing seat 6. A support frame 8 is provided at the top of the pressing mechanism. External gas can be delivered into the gas pipe 3 through the solenoid valve 301. At this time, turning the stopcock valve 2 can release the gas. At the same time, the igniter 201 controls the burner 4 to generate an electric spark to ignite it. The flame is ejected through the evenly distributed flame holes on the burner 5.
[0026] The pressing mechanism includes a pressure sensor 601 fixedly attached to the center of a fixed base 6. Slots 602 are provided at opposite ends of the upper surface of the fixed base 6. An annular seat 7 is fixedly attached to the top of the fixed base 6. An annular groove 701 is provided inside the annular seat 7. A movable ring 702 is slidably connected inside the annular groove 701. Springs 703 are evenly and circumferentially fixed to the bottom end of the movable ring 702. Pressing rods 704 are fixedly attached to the front and rear ends of the lower surface of the movable ring 702. A solenoid valve 301 is fixedly attached to the center of the gas pipe 3. When the support frame 8 is subjected to force, the movable ring 702 can compress the spring 703. At this time, the movable ring 702 can push the pressing rod 704 to insert into the slot 602 on the fixed base 6 and press the pressure sensor 601. When the pressure sensor 601 receives a pressure signal, it can control the solenoid valve 301 on the gas pipe 3 to open via the central controller, thus enabling the transmission of flue gas. When the pressure sensor 601 does not receive a pressure signal, it can control the solenoid valve 301 to close, thereby preventing the gas stove from burning dry.
[0027] The output of pressure sensor 601 is electrically connected to the input of solenoid valve 301 via a central controller, and the number of slots 602 and push rods 704 correspond to each other.
[0028] The front end of the annular seat 7 and the support frame 8 is provided with a groove for the furnace head 4 to pass through.
[0029] Example 2
[0030] The difference from Embodiment 1 is that this embodiment discloses a limiting mechanism for disassembling and replacing the support frame 8:
[0031] The limiting mechanism includes a threaded ring 801 fixedly connected to the bottom end of a support frame 8. The outer side of the threaded ring 801 is inserted into a movable ring 702. A magnetic groove 802 is formed at the center of the front end of the threaded ring 801. A movable groove 9 is formed at the center of the front end of the movable ring 702. A movable block 901 is slidably connected inside the movable groove 9. A magnetic block 902 is fixedly connected to the rear end of the movable block 901. A pull rope 903 is fixedly connected to the front end of the movable block 901. A pull block 904 is fixedly connected to the front end of the pull rope 903. When the threaded ring 801 at the bottom of the support frame 8 is inserted into the interior of the movable ring 702, the magnetic block 902 inside the movable ring 702 can be engaged in the magnetic groove 802 on the threaded ring 801, thus fixing the support frame 8 at the top of the movable ring 702. When the pull block 904 is pulled, the pull block 904 can drive the movable block 901 to move through the pull rope 903. At this time, the movable block 901 drives the magnetic block 902 to be pulled out from the magnetic groove 802 on the threaded ring 801, allowing the support frame 8 to be disassembled and replaced.
[0032] The contact surfaces of the magnetic groove 802 and the magnetic block 902 are magnetically attracted. Meanwhile, all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0033] In this embodiment, when in use: the pot is placed on the support frame 8 at the top of the stove 1. At this time, the support frame 8 receives the weight of the pot and can compress the spring 703 through the movable ring 702. At the same time, the movable ring 702 can push the bottom pressing rod 704 into the slot 602 on the fixed seat 6 and press the pressure sensor 601. When the pressure sensor 601 receives a pressure signal exceeding the threshold, it can control the solenoid valve 301 to open through the central controller, realizing the gas transmission inside the gas pipe 3. The gas can be released by rotating the stopcock valve 2. At the same time, the igniter 201 controls the burner head 4 to generate an electric spark to ignite it. The flame is sprayed out through the evenly distributed flame holes on the burner 5 to heat the bottom of the pot. When the pot is removed from the top of the support frame 8, the reaction force of the spring 703 being compressed can push the support frame 8 to rise through the movable ring 702. At this time, the movable ring 702 drives the pressing rod 704 to be pulled away from the top of the pressure sensor 601. Then, the pressure sensor 601 can control the solenoid valve 301 to close through the central controller to prevent the gas stove from burning dry.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
