[0002] A gas stove is a kitchen appliance that uses gas as fuel to cook food by generating heat through combustion. It is characterized by high efficiency, convenience, and cleanliness, and is a commonly used cooking tool in modern family kitchens.

[0003] When the gas stove is not in use, most gas stoves currently lack safety features, so children may turn on the gas stove while playing at home, causing gas to be released or ignited, posing a safety hazard. Currently, there are also commonly used hinged snap-on switch protective covers on the market, but their locking mechanism is not reliable enough and is prone to failure after frequent opening and closing. Once the snaps loosen, the protective cover may open unintentionally, losing its function of preventing accidental operation by children. Furthermore, if it is not installed securely, it also poses a risk of not effectively protecting the knob switch.

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0026] like Figure 1 As shown, this safety-protected household gas stove includes a base 1, a burner 2, and a rotary switch 3. A mounting base 4 is fixedly connected to the base 1, and a protective cover 5 is detachably connected to the mounting base 4. The rotary switch 3 is located inside the mounting base 4, and the protective cover 5 is located above the rotary switch 3. The inner side of the mounting base 4 has an annular groove 6 and a vertical groove 7. The two ends of the vertical groove 7 extend to the top of the annular groove 6 and the mounting base 4, respectively. A locking claw 8, compatible with the annular groove 6, is fixedly connected to the bottom of the protective cover 5. The mounting base 4 and the protective cover 5 form an isolation and protection for the rotary switch 3, preventing children from accessing it. When the protective cover 5 is closed, it also reduces the impact of dust and oil on the rotary switch 3. The vertical groove 7 serves as the mounting and dismounting opening for the locking claw 8 of the protective cover 5. The annular groove 6 allows the protective cover 5 to rotate while simultaneously restricting its axial movement, ensuring that the protective cover 5 can only be installed or detached from the mounting base 4 along the vertical groove 7, preventing the installed protective cover 5 from easily detaching from the mounting base 4.

[0027] like Figures 4 to 6As shown, the inner side of the mounting base 4 is also provided with a locking port 9 and a mounting groove 10. The locking port 9 and the mounting groove 10 are positioned opposite each other on both sides of the annular slide groove 6. The locking port 9 communicates with the annular slide groove 6. A spring 11 is provided in the mounting groove 10, and a stop block 12 is provided at the top of the spring 11. The stop block 12 has an arc-shaped structure. The two ends of the spring 11 are fixed to the mounting groove 10 and the stop block 12, respectively. When the spring 11 is not subjected to external force, the stop block 12 is located in the annular slide groove 6, and the locking port 9 communicates with the annular slide groove 6 but does not extend to the top of the mounting base 4. During the user's rotation of the protective cover 5, when the claw 8 moves to initial contact with the stop block 12, the spring 11 is compressed and deformed, applying a vertically upward force to the claw 8. The claw 8 initially abuts against the upper edge of the annular groove 6, applying a reverse supporting force to balance the pressure of the spring 11. As the protective cover 5 continues to rotate, the claw 8 will fully enter below the locking port 9. Since the claw 8 disengages from the upper edge of the annular groove 6, the spring 11 returns to its original deformation state, and the claw 8 is pressed into the locking port 9 by the pressure of the spring 11. At this point, the protective cover 5 cannot rotate or axially disengage from the mounting base 4, forming a locked posture. This achieves the purpose of isolating children from accessing and using the knob switch 3. Furthermore, when the protective cover 5 is in the locked state, the above structure is located inside the protective cover 5 and the mounting base 4, and cannot be seen from the outside, reducing the probability of children operating it out of curiosity. If the gas stove needs to be used, simply press the protective cover 5 to compress the spring 11 so that the claw 8 is in the same radial plane as the annular groove 6, and then rotate the protective cover 5 again to disengage the claw 8 along the vertical groove 7. Among them, the stop 12 is designed in an arc shape, which helps to reduce the resistance during its movement and contact with the claw 8 and improve the smoothness of use; the mounting base 4 is a ring structure, which has a radial limiting effect on locking the protective cover 5 and can improve the locking effect of the protective cover 5.

[0028] like Figure 6 As shown, the protective cover 5 has a flange 13 on its edge. Since the protective cover 5 will be raised to a certain height when it is locked by the spring 11, in order to avoid the formation of a gap between the mounting base 4 and the protective cover 5, a flange 13 is provided on the edge of the protective cover 5. This can reduce the entry of dust and oil stains from the outside environment when the gas stove is not in use, and reduce the frequency of cleaning.

[0029] like Figure 1 and Figure 7As shown, the burner 2 is equipped with a mounting rack 14 on its exterior. The mounting rack 14 includes an annular support 15, on which supports 16 are evenly distributed. The top of each support 16 has an inclined structure and anti-slip teeth 17. The annular support 15 helps to improve the overall stability of the mounting rack 14. The inclined structure of the supports 16 makes the supporting force of the mounting rack 14 on the wok or other cooking utensils inclined in the direction of the support. The combined supporting force of multiple supports 16 will be closer to the center of gravity of the wok, which helps to improve the stability of the wok. The anti-slip teeth 17 increase the friction of the bottom of the wok, making it difficult for the wok to wobble on the mounting rack 14, which can effectively reduce the probability of the wok tipping over and improve the safety of the user's cooking operation.

[0030] like Figure 7 As shown, there are four brackets 16, and four flame-concentrating rings 18 are fixedly connected to the outside of the four brackets 16. When the gas stove is in use, since the flame is ejected in an arc shape, the flame-concentrating rings 18 can effectively concentrate the temperature on the side of the flame and raise the temperature, thus concentrating heat and reducing the waste of gas heat diffusing to the surroundings, improving the utilization rate of gas and saving energy. At the same time, it can prevent the flame from being too large and coming into contact with the user's hand or the knob switch 3 during ignition, improving the safety of use.

[0031] like Figure 2 As shown, the base 1 is also provided with a placement groove 19, and an annular support 15 is provided on the placement groove 19, with the placement groove 19 and the annular support 15 being adapted to each other. After the annular support 15 is placed on the placement groove 19, it ensures that the placement rack 14 will not move horizontally. When the wok needs to be lifted and placed repeatedly during cooking, such as when tossing the wok, the placement rack 14 will not move relative to the wok, ensuring placement stability. The placement groove 19 is used to constrain the placement rack 14, meaning that the placement rack 14 does not need to be fixed to the base 1, and the placement rack 14 can be removed from the base 1 separately for cleaning.

[0032] like Figure 3 As shown, the bottom of the base 1 is connected to an anti-slip support 20. The anti-slip support 20 includes a foot 21 and a screw 22. The foot 21 is fixedly connected to the bottom of the screw 22, and the top of the screw 22 is threadedly connected to the base 1. The foot 21 has a conical structure. If a portable gas stove is used, the anti-slip support 20 is set to support the four corners of the base 1. The support height of the foot 21 can be adjusted through the threaded connection of the screw 22, thereby ensuring that the base 1 is level. By adjusting one or two supports 16 on one side of the base 1, it can be used for situations where the stove is uneven or the stove space is limited and there are obstructions around it.

[0033] like Figures 4 to 6As shown, the vertical groove 7 and the locking claw 8 are arranged in pairs, and the vertical groove 7 and the locking port 9 are alternately arranged along the annular slide groove 6. With the above design, the number of vertical groove 7, locking port 9 and locking claw 8 is the same. For example, when there are two of each, after the protective cover 5 is installed along the vertical groove 7, it only needs to be rotated 90 degrees to lock it, or when the protective cover 5 needs to be removed, it only needs to be rotated 90 degrees to be removed along the vertical groove 7, which is convenient for users to operate and judge.

[0034] When the gas stove is not in use, the protective cover 5 is locked as follows: the claw 8 of the protective cover 5 slides along the vertical groove 7 into the annular groove 6, and then the protective cover 5 is rotated at a certain angle. When the claw 8 contacts the stop block 12, the spring 11 is compressed and reset, pushing the claw 8 into the locking port 9, thus achieving the locked state. At this time, the protective cover 5 is restricted and cannot rotate. When the gas stove needs to be used, simply press the protective cover 5 down to make the claw 8 squeeze the spring 11, and then rotate it a certain distance to disengage from the locking port 9. When the claw 8 aligns with the vertical groove 7, it can axially disengage from the mounting base 4.

[0035] This safety-protected household gas stove features a protective cover 5 and a mounting base 4. The protective cover 5 is locked, preventing the risk of gas leakage caused by children accidentally opening the knob switch 3. The locking structure is located inside the protective cover 5 and the mounting base 4, further reducing the probability of children using it. The protective cover 5 is easy to operate, has a reliable locking effect, and is firmly installed. The rack 14 has a reasonable structural design, ensuring high stability of cooking utensils after placement during cooking, thus improving the safety of cooking operations.

[0036] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
