Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a burner cap and burner. Background Technology

[0002] As a core piece of equipment in modern kitchens, gas stoves directly affect cooking efficiency and user experience through their combustion performance. However, the burner holes on gas stoves are prone to clogging, mainly for three reasons: First, organic matter such as spilled soup and oil during cooking carbonizes at high temperatures, forming stubborn carbon deposits that firmly adhere to and block the burner holes; second, dust, particulate matter, and other impurities in the kitchen environment enter the burner holes with the airflow, causing physical blockage; and third, trace impurities in the gas itself and carbon particles produced by incomplete combustion also continuously accumulate within the pores.

[0003] Clogged burner holes directly lead to abnormal flames, such as weakened heat, yellowing flames, and unstable combustion. This not only significantly reduces thermal efficiency, causing energy waste and prolonged heating time, but also poses safety hazards due to gas leaks or abnormal combustion. Currently, users often use tools such as needles and toothpicks to manually unclog the holes, or rely on strong cleaning agents for soaking and scrubbing. However, these methods are not only cumbersome and have limited cleaning effects, but they can also easily scratch the inner walls of the burner holes, altering their precisely designed structure and diameter, thus affecting the uniformity of gas injection and the stability of combustion. For complex three-dimensional burner caps or products made of special materials (such as copper alloys), cleaning and maintenance are even more difficult.

[0004] Therefore, there is an urgent need to design a flame cap and burner to solve the above technical problems. Utility Model Content

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A flame cap is provided, comprising a flame cap body and a flame stabilizing rim disposed on the flame cap body. The flame cap body is provided with a flame hole, the flame outlet of which is located on the top surface of the flame cap body. A water-blocking strip is provided on the flame stabilizing rim, the vertical projection of which is located on the outer side of the flame cap body.

[0008] Optionally, the imaginary extension line of the flame outlet facing the side of the flame stabilizer is located outside the flame stabilizer.

[0009] Optionally, the imaginary extension line of the flame outlet facing the side of the flame stabilizer is tangent to the outer peripheral surface of the flame stabilizer.

[0010] Optionally, the water-blocking strips are connected end to end to form a water storage tank, and a drain outlet communicating with the water storage tank is provided on the water-blocking strips.

[0011] Optionally, an anti-backflow groove is provided on the side of the flame stabilizer near the main body of the flame cap, and the vertical projection of the anti-backflow groove is located on the outside of the main body of the flame cap.

[0012] Optionally, the anti-backflow groove is an annular structure, and the outer wall of the anti-backflow groove is inclined at the lower end in the vertical direction away from the main body of the flame cap.

[0013] Optionally, the water-blocking strip is an annular structure, and the inner ring of the water-blocking strip has a drainage surface, the drainage surface being inclined at its lower vertical end toward the center of the flame cap body.

[0014] Optionally, the flame stabilizer includes a main body and a connecting part, the connecting part is connected to the main body of the flame cover, the water baffle is disposed on the main body, the main body protrudes from the connecting part on the outer peripheral surface of the flame cover so that the outer peripheral surface of the flame cover forms a groove at the connecting part, and the flame outlet is located in the groove.

[0015] Optionally, the flame port includes multiple main flame ports and multiple secondary flame ports, the center of the flame inlet of the main flame port is located on a first plane, the center of the flame inlet of the secondary flame port is located on a second plane, and the first plane is located above the second plane.

[0016] Another objective of this invention is to provide a burner that can improve the problem of easy clogging of the flame holes on the burner cap, ensure the stability of flame combustion, and achieve efficient combustion.

[0017] To achieve this objective, the present invention adopts the following technical solution:

[0018] A burner is provided, including the flame cap described above.

[0019] The beneficial effects of this utility model include at least the following:

[0020] This utility model provides a flame protector, including a flame protector body and a flame stabilizer eaves disposed on the flame protector body. The flame protector body has flame holes with their outlets located on the top surface. The flame stabilizer eaves have a water-blocking strip whose vertical projection is located on the outer side of the flame protector body. In this embodiment, the flame stabilizer eaves are located above the flame protector body, and the vertical projection of the water-blocking strip on the flame stabilizer eaves is located on the outer side of the flame protector body. This allows the flame stabilizer eaves to prevent overflowing broth from directly spilling onto the flame protector body and clogging the flame holes. Furthermore, the flame outlets of the flame holes are located on the top surface of the flame protector body rather than its outer periphery, reducing the possibility of oil splattering into the flame holes during cooking, fundamentally improving the problem of easy clogging of the flame holes and ensuring the stability of the flame combustion. The burner cap body has a cylindrical structure with a top and bottom surface arranged axially opposite each other. The flame outlet is located on the top surface of the burner cap body, while the flame inlet connects to the mixing chamber of the burner cap body. The opening of the mixing chamber faces the bottom surface, allowing combustion gas to enter the mixing chamber from the bottom surface and exit through the burner outlet for combustion. The flame outlet is located on the top surface of the burner cap body, which can replenish the secondary air required for combustion in the flame outlet, achieving efficient combustion and reducing CO and NO emissions. X It effectively eliminates harmful gases while ensuring thermal efficiency, thereby improving the reliability of the cooktop and user satisfaction.

[0021] Although the fire outlet is located on the top surface of the fire cap, the imaginary extension line of the fire outlet facing the flame stabilizer is located outside the flame stabilizer. This ensures that when the flame stabilizer covers the fire cap in the vertical direction, it will not block the flames spraying out from the fire outlet, thus ensuring the combustion effect.

[0022] The imaginary extension line of the flame outlet facing the tamping eaves is tangent to the outer peripheral surface of the tamping eaves. The flame holes include multiple main flame holes, the projection of the flame outlet of each main flame hole facing the tamping eaves onto the plane of the tamping eaves is tangent to the outer peripheral surface of the tamping eaves. The flame holes also include multiple secondary flame holes, the projection of the flame outlet of each secondary flame hole facing the tamping eaves onto the plane of the tamping eaves is tangent to the outer peripheral surface of the tamping eaves. This configuration ensures a larger flow area for the main and secondary flame holes while minimizing the increase in the volume of the flame cap body.

[0023] This invention provides a burner including the aforementioned flame cap, which can improve the problem of easy clogging of the flame holes on the flame cap, ensure the stability of flame combustion, and achieve efficient combustion. Attached Figure Description

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 3 As shown, this embodiment provides a flame cover, including a flame cover body 2 and a flame stabilizer 1 disposed on the flame cover body 2. The flame cover body 2 has flame holes, with the flame outlets located on the top surface 201 of the flame cover body 2. The flame stabilizer 1 has a water-blocking strip 111, the vertical projection of which is located on the outer side of the flame cover body 2. In this embodiment, the flame stabilizer 1 is located above the flame cover body 2, and the vertical projection of the water-blocking strip 111 on the flame stabilizer 1 is located on the outer side of the flame cover body 2. This allows the flame stabilizer 1 to block overflowing broth, preventing it from directly spilling onto the flame cover body 2 and causing blockage of the flame holes. Furthermore, the flame outlets are located on the top surface 201 of the flame cover body 2 rather than its outer periphery, reducing the possibility of oil splashing into the flame holes during cooking, fundamentally improving the problem of easy blockage of the flame holes and ensuring the stability of flame combustion. In this embodiment, the burner cap body 2 has a cylindrical structure. A top surface 201 and a bottom surface 202 are axially opposite to each other on the burner cap body 2. The flame outlet of the burner hole is located on the top surface 201 of the burner cap body 2, and the flame inlet of the burner hole connects to the mixing chamber 21 of the burner cap body 2. The opening of the mixing chamber 21 faces the bottom surface 202. Combustion gas enters the mixing chamber 21 from the bottom surface 202 and can be ejected from the burner hole for combustion. The flame outlet is located on the top surface 201 of the burner cap body 2. This top surface 201 can replenish the secondary air required for combustion in the burner hole, achieving efficient combustion and reducing CO and NO emissions. X It effectively eliminates harmful gases while ensuring thermal efficiency, thereby improving the reliability of the cooktop and user satisfaction.

[0036] Optionally, such as Figure 1 As shown, although the fire outlet is located on the top surface 201 of the main body 2 of the fire cap, the imaginary extension line of the fire outlet facing the side of the flame stabilizer 1 is located on the outside of the flame stabilizer 1. This ensures that when the flame stabilizer 1 covers the soup in the vertical direction for the main body 2 of the fire cap, it will not block the flames sprayed from the fire outlet, thus ensuring the combustion effect.

[0037] In this embodiment, the imaginary extension line of the flame outlet facing the side of the flame stabilizer 1 is tangent to the outer peripheral surface of the flame stabilizer 1. For example... Figure 1 and Figure 3 As shown, the flame holes include multiple main flame holes 22. The projection of the flame outlet of the main flame hole 22 onto the plane of the flame stabilizer 1 is tangent to the outer peripheral surface of the flame stabilizer 1. The flame holes also include multiple secondary flame holes 23. The projection of the flame outlet of the secondary flame hole 23 onto the plane of the flame stabilizer 1 is tangent to the outer peripheral surface of the flame stabilizer 1. This arrangement ensures a larger flow area for the main flame holes 22 and secondary flame holes 23 while minimizing the increase in the volume of the flame cap body 2.

[0038] Furthermore, such as Figure 2 As shown, the water-blocking strips 111 are connected end to end to form a water storage tank 112. A drain outlet 113 is provided on the water-blocking strips 111, and the drain outlet 113 is connected to the water storage tank 112. The water-blocking strips 111 protrude from the top of the flame stabilizer 1, ensuring that most of the soup flowing onto the flame stabilizer 1 when overflow occurs is first stored in the water storage tank 112, and then directed through the drain outlet 113. In specific implementation, the burner cap must be installed in a position that ensures the drain outlet 113 avoids the ignition needle and thermocouple of the gas stove, preventing overflowing soup from leaking onto the ignition needle or thermocouple and causing accidental flameout.

[0039] Optionally, such as Figure 1 As shown, a backflow prevention groove 114 is provided on the side of the flame stabilizer 1 near the burner body 2. The vertical projection of the backflow prevention groove 114 is located on the outer side of the burner body 2. When overflow occurs, some soup may flow down the outer wall of the baffle strip 111 and into the backflow prevention groove 114. The soup in the backflow prevention groove 114 will drip directly down due to gravity, which can effectively prevent the soup from flowing down the flame stabilizer 1 to the top of the burner body 2 and falling onto the top surface 201 of the burner body 2, thus blocking the fire holes.

[0040] Optionally, such as Figure 1 As shown, the anti-backflow groove 114 has an annular structure, and the outer wall 1141 of the anti-backflow groove 114 slopes downwards at its lower vertical end away from the burner cap body 2. When overflow occurs, some of the soup flows into the anti-backflow groove 114 along the outer wall of the baffle strip 111, and then flows down the sloped outer wall 1141 at an accelerated speed, away from the burner cap body 2, preventing the soup from dripping onto the top surface 201 of the burner cap body 2. The anti-backflow groove 114 includes a bottom wall, an outer wall 1141, and an inner wall 1142. The bottom wall is located in the axial direction of the burner cap body 2, and the outer wall 1141 and inner wall 1142 are located in the radial direction of the burner cap body 2. The outer wall 1141 is connected to the side of the bottom wall away from the burner cap body 2, and the inner wall 1142 is connected to the side of the bottom wall close to the burner cap body 2. The inner wall 1142 of the anti-backflow groove 114 and the outer peripheral surface of the burner body 2 are spaced apart in the radial direction of the burner body 2, or the inner wall 1142 of the anti-backflow groove 114 and the outer peripheral surface of the burner body 2 are aligned in the axial direction of the burner body 2, thereby reducing the size of the main body 11 without affecting the combustion effect of the flame hole.

[0041] Optionally, such as Figure 1 and Figure 2 As shown, the baffle strip 111 has a ring structure, and the inner ring of the baffle strip 111 has a drainage surface 1121. The drainage surface 1121 is inclined at its lower vertical end towards the center of the burner body 2. Similar to the inclined arrangement of the outer wall 1141 of the anti-backflow groove 114, the drainage surface 1121 is used to guide the soup along the drainage surface 1121 of the baffle strip 111 to flow into the water storage tank 112 more quickly when overflow occurs, so as to avoid the soup accumulating on the baffle strip 111, thereby reducing the soup flowing downward along the outer wall of the baffle strip 111.

[0042] Optionally, such as Figure 1 As shown, the flame stabilizer 1 also includes a main body 11 and a connecting part 12. The connecting part 12 is connected to the main body 2 of the flame cap. A water-blocking strip 111 is provided on the main body 11. The connecting part 12 protrudes from the outer peripheral surface of the main body 11, so that the outer peripheral surface of the flame cap forms a groove 10 at the connecting part 12. That is, the outer peripheral surface of the connecting part 12 forms the bottom wall of the groove 10. The flame outlet of the flame hole is located in the groove 10 and can obtain secondary air. The connecting part 12 has an inner cavity that communicates with the mixing chamber 21. The communication between the inner cavity of the connecting part 12 and the mixing chamber 21 can effectively increase the mixing space of the gas and air, prolong the residence time of the gas in the mixing chamber 21, and make the gas flow rate entering each flame hole more uniform.

[0043] Optionally, such as Figure 1 and Figure 3 As shown, multiple main flame holes 22 and multiple secondary flame holes 23 are alternately arranged along the circumference of the burner cap body 2. The outlets of both the main flame holes 22 and the secondary flame holes 23 are located on the top surface 201 of the burner cap body 2. To ensure that the combustion gas can burn evenly around the circumference of the burner cap body 2 through both the main flame holes 22 and the secondary flame holes 23, multiple main flame holes 22 and multiple secondary flame holes 23 are evenly spaced, forming an alternating arrangement. In this embodiment, the center of the inlet of the main flame hole 22 connecting to the mixing chamber 21 is located on a first plane, and the center of the inlet of the secondary flame hole 23 connecting to the mixing chamber 21 is located on a second plane. The first plane is located above the second plane. The mixture of gas and air enters the mixing chamber 21 from below the burner cap and is then ejected through the main burner hole 22 and the secondary burner hole 23. The secondary burner hole 23, located at the bottom, is ignited first. The main burner hole 22 has a larger diameter than the secondary burner hole 23, resulting in a higher gas flow rate within the main burner hole 22. After being ignited by the flame at the secondary burner hole 23, the gas in the main burner hole 22 can provide a higher heat load.

[0044] In this embodiment, in the radial direction of the flame cap body 2, the outer edge of the flame outlet of the main flame hole 22 and the outer edge of the flame outlet of the secondary flame hole 23 are on the same fitted circle. In this embodiment, the flame outlets of the main flame hole 22 and the secondary flame hole 23 extending to the top surface 201 of the flame cap body 2 are both located close to the outer peripheral surface of the flame cap body 2, so that the volume of the flame cap body 2 and the flame stabilizer 1 can be smaller, while keeping the outer flames formed by the main flame hole 22 and the secondary flame hole 23 basically on the same plane.

[0045] This embodiment also provides a burner including the above-mentioned flame cap. The flame cap of the burner can improve the problem of easy clogging of the flame holes, ensure the stability of flame combustion, and achieve efficient combustion.

[0046] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. 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.
