[0002] Under the background of double carbon, it is necessary to improve the thermal efficiency of gas stoves. Most of the common energy-gathering devices on the market use low adaptability and large opening energy-gathering rings and other accessories, which are designed to improve thermal efficiency. For example, the invention patent with the publication number CN104121613A and the name of a multi-section contraction energy-gathering device discloses an energy-gathering ring, which is a stackable cylindrical energy-gathering ring added to an ordinary gas stove. Ventilation holes are arranged on the side wall to supplement secondary air, which can meet the universality problem caused by different heights of the pot rack and improve the adaptability of the device. However, the device has a large opening and a large heat loss, and the smoke emission generated by insufficient combustion of the flame exceeds the standard, causing environmental pollution. In addition, although the device can realize the universality problem of different pot rack heights by stacking different numbers of energy-gathering rings, the operation is not convenient and the adaptability is low. SUMMARY

[0003] In view of the above problems, the application provides a high-adaptability energy-gathering device for a gas stove, which solves the technical problems of large opening and low adaptability of the existing energy-gathering device.

[0004] In order to achieve the above purpose, the technical scheme adopted by the application is as follows:

[0005] A high-adaptability energy-gathering device for a gas stove is arranged on a gas stove eye.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] As shown in Figures 1-3 , it is a high-adaptability energy gathering device for gas stove, which is placed on the gas stove panel. The energy gathering device 1 is formed by six identical long strip-shaped energy gathering ring blades 2 stacked in petals. The energy gathering ring blades are long strip-shaped, and the six energy gathering ring blades 2 are connected in series through a thin circular ring 5 at the neck. The thin circular ring 5 passes through the middle of the energy gathering ring blade 2, and the energy gathering ring blade 2 can rotate freely around the thin circular ring 5, as shown in Figure 5 . The outside of the energy gathering ring blade at the thin circular ring is provided with a boss 8, which divides the energy gathering ring blade 2 into an upper end 25 and a lower end 21. The bottom of the energy gathering ring blade 2 is at the position of the gas stove panel. An annular sheet 4 made of permanent magnet material is arranged at the lower end 21 of the energy gathering ring blade 2.

[0026] The energy gathering ring blade 2 adopts a layered structure, as shown in Figure 4As shown, the total wall thickness of the concentrator ring blade 2 is about 7mm. From inside to outside, there are coating 22, refractory insulation material 23, and magnetic material 24. The coating 22 has two main functions: on the one hand, it improves the emissivity of the concentrator ring blade 2, thereby facilitating radiation heat exchange and improving thermal efficiency; on the other hand, it has a protective effect, preventing the concentrator ring blade 2 from being eroded. The refractory insulation material 23 insulates heat and minimizes the temperature rise of the surface of the magnetic material 24, thereby maintaining the performance of the magnetic material 24. The refractory insulation material 23 can insulate and reflect the heat of the stove flame, improving the thermal efficiency of the stove.

[0027] The magnetic material 24 has two functions: on the one hand, at the upper end 25 of the concentrator ring blade 2, the magnetic material 24 between the concentrator ring blades 2 attracts each other through N-S poles, making the concentrator device 1 form a closed space and improving thermal efficiency; through the magnetic force, the sectional concentrator ring blades are attracted together, realizing the closure of the concentrator device 1. The use of a fully enclosed structure can greatly improve thermal efficiency. On the other hand, at the lower end 21 of the concentrator ring blade 2, the annular sheet 4 and the lower end 21 of the concentrator ring blade 2 are attracted by the magnetic force, supporting the concentrator device 1 and self-adaptively adjusting the opening. The sectional structure of the concentrator ring blade makes the blade resistant to high temperature, corrosion, and deformation, and the magnetic attraction between the blades is realized.

[0028] As shown in Figure 8 , the concentrator ring blades 2 have overlapping parts, and the magnetic material 24 realizes the closure of the device through the mutual attraction of these parts. The upper end 25 of the concentrator ring blade 2 is provided with a plurality of multi-layered ventilation holes 3, the hole diameter of which gradually decreases from bottom to top. The ventilation holes 3 provide supplemental air for the flame of the stove, making the combustion more complete and complete, and the larger lower ventilation holes 3 can provide more air. The structure of the ventilation hole 3 is that the hole area of the outer side is larger than that of the inner side, and it is trumpet-shaped. The orientation of the ventilation hole 3 is perpendicular to the slope of the corresponding concentrator ring blade 2. This can maximize the intake of secondary air, making the combustion of the stove flame more complete, greatly reducing CO and NO, and improving thermal efficiency.

[0029] The head of the gas stove burner is located at the neck position of the concentrator device, forming a closed area to promote combustion. The neck diameter of the concentrator device is larger than the head diameter of the burner. Figure 8 As shown in , the bottom of the concentrator device has an annular sheet 4 made of permanent magnet material. The magnetic force between the annular sheet 4 and the petal-shaped sectional concentrator ring blade 2 supports the concentrator device and makes it automatically adapt to the weight of the pot and food, and the opening is expanded to a state that is beneficial to combustion under the corresponding situation. The bottom of the annular sheet 4 is fixed to the gas stove panel.

[0030] The self-adaptive adjustment of the energy gathering device of the present application is as follows: when no load or pot is placed on the energy gathering device 1, the annular sheet 4 is adsorbed together with the lower end part 21 of the energy gathering ring blade 2 under the action of magnetic force; with the placement of the load or pot, the upper end part 25 of the energy gathering ring blade 2 moves outward around the thin circular ring 5 under the action of force, at the same time, the lower end part 21 of the energy gathering ring blade 2 moves inward to the center away from the annular sheet 4, and is adjusted to the best open state for combustion; when the load or pot is removed after the cooking is completed, the lower end part 21 of the energy gathering ring blade 2 returns to the initial adsorption state with the annular sheet 4 under the action of magnetic force.

[0031] The high self-adaptive energy gathering device for gas stove of the embodiment of the present application can meet the self-adaptive adjustment effect under different load and different pot conditions. Figure 6 As shown in the figure, under the weight load of the common flat-bottomed pot 7, the opening angle of the energy gathering ring blade 2 is about 70°, and when the total weight of the flat-bottomed pot 7 and the food reaches 5 kg, the opening angle of the energy gathering ring blade 2 reaches the limit opening angle of about 40°. Here, the concept of opening angle is that after the energy gathering device is loaded and in a stationary state, the angle between the line connecting the center of the circle formed by the bottom of the energy gathering device and the contact point of the pot and the energy gathering device and the horizontal line.

[0032] The energy gathering device 1 can adapt to various types of pots, such as Figure 7 As shown in the figure, the common flat-bottomed pot 7 and round-bottomed pot 6 on the market can be applied. The force bearing point of the round-bottomed pot 6 is located in the area above the ventilation hole 3, which does not affect the supplement of secondary air.

[0033] In summary, the highly self-adaptive energy gathering device of the present application is arranged on the burner of the gas stove, which is composed of six identical energy gathering ring blades, the energy gathering ring blades adopt a layered structure, the energy gathering device is closed by magnetic material, the energy gathering ring blades with layered structure can withstand high temperature, corrosion and deformation, and are durable. There are multiple layers of ventilation holes on the blades, the hole diameter of the ventilation holes gradually decreases from bottom to top, which is used to supplement secondary air. The annular sheet at the bottom supports the energy gathering device by magnetic force and makes it automatically adapt to the weight of the pot and food, and the opening is expanded to a state that is conducive to combustion under the corresponding situation. The device at the bottom can ensure the bearing and stability of the entire energy gathering device, and realize the self-adaptive effect. The energy gathering device of the present application can meet the self-adaptive adjustment effect under different load and different pot conditions, realize the adjustable energy gathering and reflection of heat, positively respond to the policy of carbon peak and carbon neutralization of the country, and improve the thermal efficiency of the gas stove.

[0034] The above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by ordinary skilled in the art within the essential scope of the present application shall be considered as falling within the protection scope of the present application.
