Description

Technical Field

[0001] This utility model relates to a protective ring, and more particularly to a protective ring for a gas stove. Background Technology

[0002] In existing gas stoves, a support frame is installed on the burner head to support the cookware for easy placement. In order to prevent the flame from overflowing when the gas stove is working, a protective ring is installed on the support frame to prevent the flame from overflowing.

[0003] In existing technologies, such as the one disclosed in CN222230648U, the energy-concentrating protective ring with an arc-shaped structure can effectively transfer the temperature output from the side of the flame to the top through the energy-concentrating protective ring. This avoids the situation where the temperature is conducted to the panel and causes the panel temperature to rise rapidly, effectively preventing the tempered glass panel from cracking due to temperature. This greatly improves the safety of the gas stove. At the same time, the use of the movable energy-concentrating protective ring and the support rod allows the device to be adapted to woks of different sizes, greatly improving the practicality of the device.

[0004] However, it still has some shortcomings. In the above technical solution, although the exhaust holes are evenly distributed on the protective ring, the characteristics of the gas stove flame distribution are not considered (such as the greatest oxygen demand at the bottom of the flame when it is burning). In this case, evenly opening exhaust holes on the protective ring will reduce the combustion effect of the gas due to insufficient local oxygen supply, which will increase carbon dioxide emissions. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a protective ring for a gas stove that can ensure the combustion effect of gas.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is a protective ring for a gas stove, including an annular connecting seat connected to the gas stove. Multiple support blocks for supporting cookware are evenly arranged on the connecting seat. A protective ring is provided on the outer wall of the multiple support blocks. The protective ring has multiple exhaust holes arranged in a gradient on the protective ring, namely a high-density area, a medium-density area, and a low-density area. The high-density area is located at the bottom of the protective ring. The diameter of the exhaust holes in the high-density area is larger than that in the medium-density area, and the diameter of the exhaust holes in the medium-density area is larger than that in the low-density area. The low-density area is located at the top of the protective ring.

[0007] A further preferred embodiment of this utility model is as follows: a plurality of first mounting holes are evenly provided on the bottom surface of the protective ring, and a plurality of second mounting holes aligned with the first mounting holes are provided on the connecting seat. Each of the second mounting holes is provided with an elastic component, the top of the elastic component is connected to the first mounting hole, and the elastic component is used to push the top of the protective ring to abut against the outer wall of the pot.

[0008] A further preferred embodiment of this utility model is as follows: each of the support blocks has a T-shaped connecting block on the side wall near the protective ring, and the inner wall of the protective ring has a T-shaped groove that matches the connecting block, and the connecting block is slidably connected to the T-shaped groove.

[0009] A further preferred embodiment of this utility model is that the support blocks are arranged in a multi-step shape on the side away from the protective ring.

[0010] A further preferred embodiment of this utility model is that the inner wall of the protective ring is coated with a ceramic-based reflective coating.

[0011] A further preferred embodiment of this utility model is that the support blocks are all detachably connected to the connecting seats by bolts.

[0012] A further preferred embodiment of this utility model is as follows: each of the elastic components includes a telescopic rod, which is installed in the second mounting hole, and the telescopic end of the telescopic rod is connected to the first mounting hole; two abutment plates are provided, which are respectively installed at the top and bottom of the telescopic rod, and the size of the abutment plates is smaller than the diameter of the first and second mounting holes; and a spring is sleeved on the telescopic rod, with the bottom and top of the spring abutting against the two abutment plates respectively, and the spring is made of a high-temperature resistant material.

[0013] Compared with the prior art, the advantages of this utility model are that, in order to ensure the combustion effect of the flame inside the protective ring, multiple exhaust holes (such as high-density areas, medium-density areas, and low-density areas) are provided on the protective ring in a gradient arrangement. Because the gas concentration at the root of the flame is high when the gas stove is in use, the exhaust holes are distributed in a high-density manner at the bottom of the protective ring to ensure that the gas can be fully burned. At the same time, in order to avoid excessive cold air diluting the heat of the flame, the exhaust holes are distributed in a medium-density manner in the middle of the protective ring. And in order to ensure that the top of the flame can stably heat the bottom of the pot, the exhaust holes are distributed in a low-density manner in the middle of the protective ring. In this way, by setting the exhaust holes in a gradient arrangement on the protective ring, the gas can be fully burned, while reducing carbon dioxide emissions. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0026] This embodiment mainly describes the structure of a protective ring for a gas stove, as detailed below:

[0027] like Figures 1-8 As shown, a protective ring for a gas stove includes an annular connecting seat 1 connected to the gas stove and a support block 3 mounted on the connecting seat 1 for supporting cookware. To ensure the stability of the support block 3 in supporting the cookware, multiple support blocks 3 are arranged circumferentially around the connecting seat 1. To prevent flame overflow during gas stove use, a protective ring 2 is provided on the outer wall of the support block 3. Furthermore, to ensure effective combustion of the flame inside the protective ring 2, multiple gradient-arranged exhaust holes 21 (such as high-density zone 5, medium-density zone 6, and low-density zone 7) are provided on the protective ring 2. Because the gas concentration at the base of the flame is high during gas stove use, multiple exhaust holes 21 are provided to ensure complete combustion and ventilation. The vents 21 are distributed at a high density at the bottom of the protective ring 2. To avoid excessive cold air diluting the heat of the flame, the vents 21 are distributed at a medium density in the middle of the protective ring 2. To ensure that the top of the flame can stably heat the bottom of the pot, the vents 21 are distributed at a low density in the middle of the protective ring 2. By setting the vents 21 in a gradient on the protective ring 2, the gas can be fully burned, while reducing carbon dioxide emissions. In order to ensure the effectiveness of the vents 21, the diameter of the vents 21 in the high-density zone 5 is larger than that in the medium-density zone 6, and the diameter of the vents 21 in the medium-density zone 6 is larger than that in the low-density zone 7.

[0028] Furthermore, to ensure that the top of the protective ring 2 can abut against the bottom of the pot, multiple first mounting holes 23 are evenly provided on the bottom surface of the protective ring 2, and multiple second mounting holes 11 aligned with the first mounting holes 23 are provided on the connecting seat 1. An elastic component 4 is provided in each of the second mounting holes 11, and the top of the elastic component 4 is connected to the first mounting hole 23. Thus, when the pot is placed on the support block 3, the outer wall of the bottom of the pot abuts against the top of the protective ring 2. This can better prevent the problem of flame overflow. The setting of the elastic component 4 can ensure the effect of the top of the protective ring 2 abutting against the outer wall of the bottom of the pot. The elastic force of the elastic component 4 is less than the pressure of the pot on the protective ring 2, which can prevent the elastic component 4 from pushing the protective ring 2 and causing the pot to be overturned.

[0029] Furthermore, to facilitate maintenance of the elastic component 4, each elastic component 4 includes a telescopic rod 41 installed in the second mounting hole 11, with the telescopic end of the telescopic rod 41 connected to the first mounting hole 23. A stop plate 42 is provided at the top and bottom of the telescopic rod 41, and the size of the stop plate 42 is smaller than the diameter of the first mounting hole 23 and the second mounting hole 11. Finally, a spring 43 is fitted onto the telescopic rod 41, with the bottom and top of the spring 43 abutting against the two stop plates 42 respectively. Thus, when the elastic component 4 needs to be replaced, the telescopic rod 41 along with the spring 43 can be removed from the first mounting hole 23 and the second mounting hole 11, facilitating maintenance of the elastic component 4. To ensure the service life of the spring 43, the spring 43 is made of a high-temperature resistant material (nickel-based alloy helical spring 43).

[0030] Furthermore, in order to ensure the stability of the protective ring 2 when it moves, a T-shaped connecting block 31 is provided on the side wall of the support block 3 on the side closest to the protective ring 2, and a T-shaped groove 22 matching the connecting block 31 is provided on the inner wall of the protective ring 2, so that the T-shaped groove 22 slides along the connecting block 31 when the protective ring 2 moves.

[0031] Furthermore, in order to improve the heat reflection of the flame by the protective ring 2, a ceramic-based reflective coating is sprayed on the inner wall of the protective ring 2.

[0032] In order to ensure that the support block 3 can support cookware of different sizes, the support block 3 is set in a multi-step shape on the side away from the protective ring 2. At the same time, in order to facilitate the disassembly and assembly of the support block 3, the support block 3 is detachably connected to the connecting seat 1 by bolts.

[0033] The above provides a detailed description of the protective ring for a gas stove provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
