Description

Technical Field

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

[0002] A stove is a basic piece of equipment in the kitchen used for cooking food. It heats food by burning gas. The burner is the core component of the stove; it is responsible for mixing gas with air and igniting it to produce heat.

[0003] Currently, the heat output at the center of the burner is lower than that at the outer ring burner to meet users' low-heat needs. When the burner is used for high-heat cooking, because the heat output at the center burner is lower than that at the outer ring burner, and because there is a certain distance between the center burner and the bottom of the pan, the central flame at the center burner heats the pan less effectively than the outer flame at the outer ring burner, thus affecting the user's cooking experience. Utility Model Content

[0004] One of the technical problems solved by this invention is to provide a burner that helps to reduce the heating difference between the flame at the center burner cap and the flame at the outer ring burner cap on the cookware.

[0005] The above-mentioned technical problems are solved by the following technical solutions:

[0006] A burner, comprising:

[0007] The seat body is provided with an outer ring airway and a central airway;

[0008] An outer ring flame cap is installed on the outer ring air passage;

[0009] An inner tube is provided on the seat body, and the first end of the inner tube is connected to the central airway.

[0010] A first magnetic attraction structure is provided on the base body;

[0011] A floating tube, wherein the first end of the floating tube is slidably sleeved on the inner tube, and the floating tube has a high position and a low position relative to the inner tube;

[0012] A central flame cap is installed at the second end of the floating tube. When the floating tube is in the high position, the central flame cap is higher than the outer ring flame cap.

[0013] A second magnetic attraction structure is provided on the floating tube. The first magnetic attraction structure and the second magnetic attraction structure repel each other and can drive the floating tube to slide towards the higher position.

[0014] The burner described in this utility model has the following advantages compared with the prior art:

[0015] When the burner is applied to a flat-bottomed pan, the floating tube remains in a high position due to the mutual repulsion between the first and second magnetic structures, with the central flame cap resting against the bottom of the pan. When the burner is applied to a pointed-bottomed pan, the bottom of the pan presses against the central flame cap, overcoming the mutual repulsion between the first and second magnetic structures and pushing the floating tube towards a lower position. In other words, regardless of whether the burner is applied to a flat-bottomed or pointed-bottomed pan, the central flame cap remains against the bottom of the pan due to the mutual repulsion between the first and second magnetic structures. This improves the utilization rate of the heat from the central flame at the central flame cap, reduces the heating difference between the central flame at the central flame cap and the outer ring flame at the outer ring flame cap, and enhances the user's cooking experience.

[0016] In one embodiment, the base has a recess surrounding the inner tube, and the first end of the floating tube is slidably inserted into the recess;

[0017] The first magnetic attraction structure is provided on the side wall of the settling tank, and / or the first magnetic attraction structure is provided on the bottom of the settling tank.

[0018] In one embodiment, a guide block is provided on the outer periphery of the first end of the floating tube, and a guide groove is provided on the side wall of the sinking trough, with the guide block slidably disposed in the guide groove.

[0019] In one embodiment, the top of the guide rail groove extends through the base body, and the burner further includes a limiting member that covers the top of the guide rail groove.

[0020] In one embodiment, the guide rail groove has a first mounting groove on its groove wall, and the first magnetic attraction structure is disposed in the first mounting groove;

[0021] The guide block is provided with a second mounting groove, and the second magnetic structure is disposed in the second mounting groove.

[0022] In one embodiment, the first end of the inner tube is inserted into the central airway, and the second end of the inner tube protrudes from the sink.

[0023] In one embodiment, the first magnetic attraction structure includes at least two first magnetic blocks arranged circumferentially along the inner tube; or, the first magnetic attraction structure is a magnetic ring.

[0024] In one embodiment, the second magnetic structure includes at least two second magnetic blocks arranged circumferentially along the floating tube; or, both the first magnetic structure and the second magnetic structure are magnetic rings.

[0025] In one embodiment, the burner further includes a third magnetic attraction structure disposed on the base, the third magnetic attraction structure being located above the first magnetic attraction structure, and the second magnetic attraction structure magnetically attracting the third magnetic attraction structure when in the high position.

[0026] In one embodiment, the third magnetic attraction structure includes at least two third magnetic blocks arranged circumferentially along the inner tube; or, the first magnetic attraction structure is a magnetic ring. Attached Figure Description

[0048] Reference Figures 1 to 4 As shown, this embodiment provides a burner, which includes a base 100, an outer ring flame cap 200, an inner tube 300, a first magnetic attraction structure 400, a floating tube 500, a central flame cap 600, and a second magnetic attraction structure 700.

[0049] The base 100 is provided with an outer ring air passage 101 and a central air passage 102. An outer ring flame cap 200 covers the outer ring air passage 101. An inner tube 300 is provided on the base 100, with its first end connected to the central air passage 102. A first magnetic attraction structure 400 is provided on the base 100. The first end of a floating tube 500 is slidably sleeved on the inner tube 300, and the floating tube 500 has high and low sliding positions relative to the inner tube 300. A central flame cap 600 covers the second end of the floating tube 500; when the floating tube 500 is in the high position, the central flame cap 600 is higher than the outer ring flame cap 200. A second magnetic attraction structure 700 is provided on the floating tube 500; the first magnetic attraction structure 400 and the second magnetic attraction structure 700 repel each other, driving the floating tube 500 to slide towards the high position.

[0050] For example, the inner tube 300 is threadedly fastened to the seat 100.

[0051] For example, the base 100 is provided with a burner head 110 for introducing gas.

[0052] For example, the gas can flow through the outer ring gas passage 101 to the outer ring burner cap 200 and be ignited to form a central flame.

[0053] For example, the gas can flow through the central gas passage 102 to the outer ring burner cap 200 and be ignited to form an outer ring flame.

[0054] When the burner is applied to the frying pan 10, such as Figure 3 As shown, under the mutual repulsion of the first magnetic attraction structure 400 and the second magnetic attraction structure 700, the floating tube 500 remains in a high position, and the central flame cap 600 abuts against the bottom of the frying pan 10. In other embodiments, the central flame cap 600 does not abut against the bottom of the frying pan 10, and there is a small gap; or, the central flame cap 600 abuts against the bottom of the frying pan 10, which can cause the floating tube 500 to move a small distance towards a lower position.

[0055] When the burner is applied to the pointed bottom pan 20, such as Figure 4 As shown, the bottom of the pointed-bottom pot 20 presses against the center fire cap 600, which can overcome the mutual repulsion between the first magnetic attraction structure 400 and the second magnetic attraction structure 700, and push the floating tube 500 to a lower position.

[0056] Understandably, whether the burner is applied to a flat-bottomed pan 10 or a pointed-bottomed pan 20, under the mutual repulsion of the first magnetic attraction structure 400 and the second magnetic attraction structure 700, the central flame cap 600 can be pressed against the bottom of the pan, which helps to improve the utilization rate of the heat of the central flame, reduce the heating difference between the central flame and the outer ring flame on the cookware, and improve the user's cooking experience.

[0057] Understandably, the mutual repulsion between the first magnetic structure 400 and the second magnetic structure 700 can balance the downward pressure of the cookware, allowing the cookware to be placed stably on the burner.

[0058] Understandably, when the cookware is removed from the burner, the floating tube 500 can remain in a high position due to the mutual repulsion between the first magnetic structure 400 and the second magnetic structure 700.

[0059] In one feasible embodiment, the first magnetic attraction structure 400 includes at least two first magnetic blocks 410 arranged circumferentially along the inner tube 300 for easy installation. In another feasible embodiment, the first magnetic attraction structure 400 is a magnetic ring for easy installation.

[0060] For example, the first magnetic attraction structure 400 can be a permanent magnet or an electromagnetic component.

[0061] In one feasible embodiment, the second magnetic structure 700 includes at least two second magnetic blocks 710 arranged circumferentially along the floating tube 500 for easy installation. In another feasible embodiment, both the first magnetic structure 400 and the second magnetic structure 700 are magnetic rings for easy installation.

[0062] For example, the second magnetic attraction structure 700 can be configured as a permanent magnet.

[0063] In some embodiments, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the base 100 has a recess 103 surrounding the inner tube 300, and the first end of the floating tube 500 is slidably inserted into the recess 103, which helps to improve the stability of the sliding of the floating tube 500.

[0064] For example, when the first end of the floating tube 500 is in a low position, it can abut against the bottom of the settling tank 103 to form a limit, which is stable and reliable.

[0065] In one feasible implementation, a first magnetic structure 400 is provided on the side wall of the sink 103, for example, a first magnetic block 410 is provided on the side wall of the sink 103 to facilitate assembly.

[0066] In another feasible implementation, a first magnetic attraction structure 400 is provided at the bottom of the sink 103, for example, a magnetic ring. The first magnetic attraction structure 400 is provided at the bottom of the sink 103 to facilitate assembly.

[0067] In some embodiments, a guide block 510 is provided on the outer periphery of the first end of the floating tube 500, and a guide groove 104 is provided on the side wall of the sink 103. The guide block 510 is slidably disposed in the guide groove 104 to prevent the floating tube 500 from rotating and to improve the stability of the sliding of the floating tube 500.

[0068] For example, at least two guide blocks 510 are provided at circumferential intervals along the floating tube 500, such as three to six, and the guide rail grooves 104 are provided in a one-to-one correspondence with the guide blocks 510.

[0069] In one feasible embodiment, the top of the guide rail groove 104 extends through the base 100, and the burner also includes a limiting member 800, which covers the top of the guide rail groove 104 for easy assembly. It is understood that when the guide block 510 abuts against the limiting member 800, the floating tube 500 is positioned at a high position, forming a limit, which helps prevent the floating tube 500 from detaching from the inner tube 300.

[0070] For example, the limiting member 800 can be configured as a ring structure, and the limiting member 800 is sleeved outside the floating tube 500 for convenient positioning and assembly.

[0071] For example, the limiting member 800 can be fastened to the seat 100 by bolts.

[0072] For example, the guide rail groove 104 has a first mounting groove 105 on its groove wall, and the first magnetic structure 400 is disposed in the first mounting groove 105, which facilitates the positioning and assembly of the first magnetic structure 400 and results in a compact structure. For example, the first magnetic block 410 is provided in a one-to-one correspondence with the first mounting groove 105, and the first magnetic block 410 is disposed in the corresponding first mounting groove 105. For example, the first mounting groove 105 can be disposed on the bottom wall of the guide rail groove 104 away from the central axis of the recess 103.

[0073] For example, the guide block 510 is provided with a second mounting groove 511, and the second magnetic structure 700 is disposed in the second mounting groove 511. This facilitates the positioning and assembly of the second magnetic structure 700, resulting in a compact structure. Furthermore, it allows the floating tube 500 to maintain a larger thickness at the second mounting groove 511, which helps improve the structural strength of the floating tube 500. Alternatively, the second magnetic block 710 can be arranged in a one-to-one correspondence with the second mounting groove 511, with the second magnetic block 710 disposed within the corresponding second mounting groove 511.

[0074] For example, along the circumference of the floating tube 500, the width of the guide block 510 is equal to the width of the second mounting groove 511. It is understood that the second magnet 710 can act as a guide block 510, which slides in contact with the guide rail groove 104 due to the missing portion of the second mounting groove 511, resulting in a compact structure.

[0075] For example, along the radial direction of the floating tube 500, the thickness of the guide block 510 is less than the thickness of the second magnetic block 710, and the side of the guide block 510 away from the central axis of the floating tube 500 is flush with the side of the corresponding second magnetic block 710 away from the central axis of the floating tube 500, or the side of the guide block 510 away from the central axis of the floating tube 500 protrudes beyond the side of the corresponding second magnetic block 710 away from the central axis of the floating tube 500. In a feasible embodiment, the first end of the inner tube 300 is inserted into the central air passage 102, and the second end of the inner tube 300 protrudes from the recess 103, which helps to improve the stability of the sliding of the floating tube 500 and helps to prevent the floating tube 500 from detaching from the inner tube 300.

[0076] In some embodiments, continue to refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the burner also includes a third magnetic structure 900 disposed on the base 100. The third magnetic structure 900 is located above the first magnetic structure 400, and the second magnetic structure 700 is magnetically attracted to the third magnetic structure 900 when it is in a high position. In this embodiment, the first magnetic structure 400 and the second magnetic structure 700 repel each other, while the second magnetic structure 700 and the third magnetic structure 900 are magnetically attracted to each other. This helps the floating tube 500 to remain stable when it is in a high position and can reduce the magnetic repulsive force exerted on the second magnetic structure 700 by the first magnetic structure 400 when the floating tube 500 is in a low position, thereby improving the stability of the cookware placed on the burner.

[0077] In one feasible embodiment, the third magnetic attraction structure 900 includes at least two third magnetic blocks 910 arranged circumferentially along the inner tube 300. For example, a third mounting groove 106 is provided on the groove wall of the guide rail groove 104, and the third magnetic blocks 910 are correspondingly arranged in the third mounting grooves 106. The third magnetic blocks 910 are disposed in the corresponding third mounting grooves 106, which facilitates the positioning and assembly of the third magnetic blocks 910. In another feasible embodiment, the third magnetic attraction structure 900 is a magnetic ring. For example, the third magnetic attraction structure 900 configured as a magnetic ring is disposed at the end of the recess 103 for easy installation.

[0078] For example, the third magnetic attraction structure 900 can be a permanent magnet or an electromagnetic component.

[0079] In some embodiments, the base 100 is provided with at least one outer ring air passage 101, such as two, and the outer ring flame cap 200 is provided in a one-to-one correspondence with the outer ring air passage 101, with the outer ring flame cap 200 covering the corresponding outer ring air passage 101.

[0080] In some embodiments, at least part of the outer ring flame cap 200 can be configured as a floating structure, that is, the outer ring flame cap 200 can move up and down. Its specific connection structure is similar to the connection method of the central flame cap 600, and will not be described in detail in this embodiment.

[0081] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0082] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
