Description

Technical Field

[0001] This invention relates to the field of stove technology, and in particular to an inner ring burner cap and burner. Background Technology

[0002] Traditional inner-ring burner caps typically cannot adjust the size of the burner orifices, and dirt easily accumulates inside the orifices, making them difficult to clean. Current technology often designs the inner-ring burner cap as a separate unit to control or clean the burner orifices. However, while separate burner caps facilitate flame control adjustment and cleaning, they suffer from poor flame stability and are prone to flame lift-off under cold or high-pressure conditions. Furthermore, current technology usually requires manual adjustment of the burner orifices, which is cumbersome and makes it difficult to automatically adjust the burner orifice size using the power of the gas. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art where the size of the adjusting flame hole of the inner ring burner needs to be manually adjusted and it is difficult to automatically adjust it by gas power, and to provide an inner ring burner and burner.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This invention provides an inner ring flame cap, which includes a flame cap body with a plurality of flame holes. The inner ring flame cap also includes an adjusting member. The flame cap body has a placement groove that matches the shape of the adjusting member. The adjusting member can be inserted into and penetrate the placement groove to divide the flame holes into a first segment and a second segment. The first segment is located on the radially inner side of the adjusting member, and the second segment is located on the radially outer side of the adjusting member. The adjusting member is not parallel to the extension direction of the flame holes.

[0006] The regulating member is provided with a plurality of regulating holes that penetrate the regulating member. The two ends of the regulating holes are respectively connected to the first hole segment and the second hole segment. The regulating hole is provided with a regulating plate, which is driven by the gas flowing through the regulating hole to adjust the opening size of the regulating hole.

[0007] In this design, the inner ring burner cap includes a burner cap body and an adjusting component. The burner cap body has multiple burner holes and a placement groove that matches the shape of the adjusting component. The adjusting component can be inserted into and penetrate the placement groove to divide the burner holes into a first segment and a second segment. The adjusting component has multiple adjusting holes that penetrate it, with the two ends of each hole connecting to the first and second segments respectively. Adjusting plates are provided on the adjusting holes, which can be driven by the gas flowing through them to adjust the opening size of the holes. This allows the inner ring burner cap to automatically adjust the burner hole size using gas power, eliminating the need for manual adjustment and making burner hole adjustment more convenient.

[0008] Preferably, the adjusting plate extends downward at an angle from the radially inner side to the radially outer side of the inner ring burner cap, so that the adjusting plate can be in a closed state under its own weight when not under the action of gas power.

[0009] In this design, the regulating plate is inclined and extends downward in the radial direction from the inner side to the outer side of the inner ring burner. This allows the regulating plate to be in a closed state under its own weight when not under the action of gas power. When the inner ring burner is burning, the regulating plate can be opened under the drive of gas power, and the opening size of the regulating plate can be changed according to the magnitude of gas power. When the inner ring burner stops working, the regulating plate can be automatically closed under its own weight, thereby achieving the effect of automatically adjusting the opening and closing state of the regulating hole through gas power.

[0010] Preferably, the regulating plate includes a connecting part and a valve plate, the connecting part is connected to the regulating hole, and one end of at least one valve plate is movably connected to the connecting part, the valve plate being able to open at least in the direction of gas flow.

[0011] In this solution, the regulating plate has a specific structure including a connecting part and a valve plate. The connecting part is connected to the regulating hole, and one end of at least one valve plate is movably connected to the connecting part. The valve plate can open at least in the direction of gas flow. When the gas flows through the regulating hole, the gas power drives the valve plate to move around the connecting part, changing the rotation angle of the valve plate, thereby adjusting the opening size of the regulating hole.

[0012] Preferably, the connecting part is located in the middle of the adjusting hole, and the two valve plates are respectively located on both sides of the connecting part.

[0013] In this design, there can be two valve plates. The connecting part is located in the middle of the regulating hole, and the two valve plates are respectively located on both sides of the connecting part. When the gas flows through the regulating hole, the valve plates can open on both sides of the connecting part. By using two valve plates, each valve plate is smaller and easier to open than a single valve plate, making the valve plate adjustment more sensitive. Furthermore, if one valve plate fails, the other valve plate can still ensure the normal operation of the regulating hole, improving the fault tolerance of the regulating plate. By placing the connecting part in the middle, the gas power received by the two valve plates can be more even, further improving the regulating effect of the valve plates.

[0014] Preferably, the adjusting member is rotatable circumferentially along the inner ring flame cap to change the overlapping area of ​​the adjusting hole and the flame hole in the radial direction of the inner ring flame cap.

[0015] In this design, based on the automatic adjustment of the regulating plate according to the gas power, the user can adjust the size of the regulating orifice by rotating the regulating component. When the user needs to adjust the burner orifice, the regulating component can be rotated circumferentially along the inner ring burner cap, thereby changing the overlapping area of ​​the regulating orifice and the burner orifice in the radial direction of the inner ring burner cap. In other words, the area of ​​the regulating orifice within the burner orifice is adjusted, thus adjusting the size of the burner orifice. Moreover, when the regulating component is rotated, it can also dismantle the dirt accumulated in the burner orifice, making the dirt particles smaller. When the regulating component is removed, it is easier for the dirt to flow out, making it easier to clean the burner orifice.

[0016] Preferably, at least some of the adjustment holes and the fire holes correspond one-to-one in the circumferential direction of the adjustment member.

[0017] In this solution, by corresponding at least some of the adjusting holes with the flame holes in the circumferential direction of the adjusting component, the flame hole size of multiple flame holes in the circumferential direction of the inner ring flame cap can be adjusted. When the adjusting component rotates, the relative positions of multiple flame holes and adjusting holes can be adjusted, making the adjustment of flame hole size more convenient.

[0018] Preferably, when the adjusting member is rotated to the point where the adjusting hole and the fire hole are misaligned, the inner wall of the placement groove can limit the opening size of the adjusting plate.

[0019] In this solution, when the adjusting component is rotated to the point where the adjusting hole and the flame hole are misaligned, the adjusting hole portion is located within the placement groove. The inner wall of the placement groove restricts the opening size of the adjusting plate, which in turn restricts the size of the adjusting hole, thus allowing the user to adjust the size of the flame hole by rotating the adjusting component.

[0020] Preferably, in the direction from the radially inner side to the radially outer side of the inner ring fire cap, the first hole segment extends obliquely downward and the second hole segment extends obliquely upward;

[0021] And / or, the adjusting member and the placement groove extend in the vertical direction.

[0022] In this design, the first hole segment is extended diagonally downward and the second hole segment is extended diagonally upward in the direction from the radial inner side to the radial outer side of the inner ring burner cap, so that the burner hole is V-shaped as a whole. When dirt enters the burner hole, it will accumulate at the bottom of the V-shaped burner hole, and the adjusting component is exactly at the bottom of the V-shaped burner hole. When the adjusting component is rotated, it can better clean the dirt accumulated at the bottom of the V-shaped burner hole and reduce burner hole blockage.

[0023] By setting the adjustment component and placement slot to extend vertically, it is easier for users to put the adjustment component into the placement slot. At the same time, when the adjustment component is disassembled, it is easier for dirt in the fire hole to flow out vertically. The vertically extending adjustment component and placement slot are also easier to manufacture.

[0024] Preferably, the opening of the placement groove is located at the lower end of the flame cap body, and the adjusting member is inserted into the placement groove from the lower end of the flame cap body;

[0025] And / or, the adjusting member is further provided with a positioning member, which extends from the lower end of the adjusting member toward the radially inner side of the adjusting member.

[0026] In this solution, by setting the opening of the placement slot at the lower end of the flame cap body, and inserting the adjusting component into the placement slot from the lower end of the flame cap body, the opening of the placement slot can be hidden, preventing the opening of the placement slot from being exposed on the outside of the inner ring flame cap. It also facilitates the flow of dirt from the flame hole out from the bottom of the inner ring flame cap during cleaning, and also facilitates the installation and removal of the adjusting component.

[0027] By setting a positioning element on the adjusting element, the user can rotate the positioning element to drive the adjusting element to rotate, which makes it easier for the user to operate. At the same time, by observing the position of the positioning element, it is easier to determine the rotation angle of the adjusting element. By extending the positioning element from the lower end of the adjusting element to the radially inner side of the adjusting element, it is easier for the user to rotate the positioning element circumferentially along the inner ring fire cover.

[0028] The present invention also provides a burner comprising the aforementioned inner ring flame cap.

[0029] The positive and progressive effects of this invention are as follows:

[0030] The inner ring burner cap includes a burner cap body and an adjusting component. The burner cap body has multiple burner holes and a placement groove that matches the shape of the adjusting component. The adjusting component can be inserted into and pass through the placement groove to divide the burner holes into a first hole segment and a second hole segment. The adjusting component has multiple adjusting holes that pass through it, with the two ends of each hole connecting to the first hole segment and the second hole segment, respectively. Adjusting plates are provided on the adjusting holes, and these plates can be driven by the gas flowing through them to adjust the opening size of the adjusting holes. This allows the inner ring burner cap to automatically adjust the burner hole size using gas power, eliminating the need for manual adjustment by the operator and making burner hole adjustment more convenient.

[0051] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the following embodiments.

[0052] This embodiment provides a burner, which includes an inner ring flame cap 100.

[0053] like Figures 1-3As shown, the inner ring flame cap 100 includes a flame cap body 200, on which a plurality of flame holes 210 are provided. The inner ring flame cap 100 also includes an adjusting member 300. The flame cap body 200 is provided with a placement groove 220 that matches the shape of the adjusting member 300. The adjusting member 300 can be inserted into and pass through the placement groove 220 to divide the flame holes 210 into a first hole segment 211 and a second hole segment 212. The first hole segment 211 is located on the radial inner side of the adjusting member 300, and the second hole segment 212 is located on the radial outer side of the adjusting member 300. The extending direction of the adjusting member 300 is not parallel to that of the flame holes 210.

[0054] like Figures 4-7 As shown, the adjusting member 300 is provided with a plurality of adjusting holes 310 penetrating the adjusting member 300. The two ends of the adjusting hole 310 are respectively connected to the first hole section 211 and the second hole section 212. The adjusting hole 310 is provided with an adjusting plate 320. The adjusting plate 320 is driven by the gas flowing through the adjusting hole 310 to adjust the opening size of the adjusting hole 310, so that the inner ring burner cap 100 can automatically adjust the size of the burner hole 210 by gas power, without the need for manual adjustment by the operator, making the adjustment of the burner hole 210 of the inner ring burner cap 100 more convenient.

[0055] In the radially inner to radially outer direction of the inner ring burner cap 100, the adjusting plate 320 extends downward at an angle so that when the adjusting plate 320 is not under the action of gas power, it can be in a closed state under its own weight. When the inner ring burner cap 100 is burning, the adjusting plate 320 can be opened under the drive of gas power, and the opening size of the adjusting plate 320 can be changed according to the magnitude of gas power. When the inner ring burner cap 100 stops working, the adjusting plate 320 can be automatically closed under its own weight, thereby achieving the effect of automatically adjusting the opening and closing state of the adjusting hole 310 by gas power.

[0056] The regulating plate 320 includes a connecting portion 321 and a valve plate 322. The connecting portion 321 is connected to the regulating hole 310, and at least one end of the valve plate 322 is movably connected to the connecting portion 321. The valve plate 322 is designed to open at least in the direction of gas flow. When gas flows through the regulating hole 310, the gas power drives the valve plate 322 to move around the connecting portion 321, changing the rotation angle of the valve plate 322, thereby adjusting the opening size of the regulating hole 310.

[0057] There can be two valve plates 322. The connecting part 321 is located in the middle of the regulating hole 310, and the two valve plates 322 are respectively located on both sides of the connecting part 321. When the gas flows through the regulating hole 310, the valve plates 322 can open on both sides of the connecting part 321. By setting two valve plates 322, compared with setting one valve plate 322, each valve plate 322 is smaller and easier to open, and the valve plate 322 adjustment is more sensitive. Moreover, when one valve plate 322 fails, the other valve plate 322 can still ensure the normal operation of the regulating hole 310, thus improving the fault tolerance of the regulating plate 320. By setting the connecting part 321 in the middle, the gas power received by the two valve plates 322 can be more even, further improving the adjustment effect of the valve plates 322.

[0058] In this embodiment, there are two valve plates 322. In other embodiments, there may be one valve plate 322, and those skilled in the art can also choose other suitable numbers of valve plates 322.

[0059] In this embodiment, the valve plate 322 is semi-circular. In other embodiments, other shapes of the valve plate 322 that are deemed suitable by those skilled in the art may also be selected.

[0060] In this embodiment, the connecting part 321 is located in the middle of the adjusting hole 310, and the two valve plates 322 are respectively located on both sides of the connecting part 321. In other embodiments, the connecting part 321 may also be located at one end of the adjusting hole 310, and the valve plate 322 may be located on one side of the connecting part 321. Those skilled in the art may also choose other suitable positions for the connecting part 321 and the valve plate 322.

[0061] In this embodiment, the connecting portion 321 extends vertically. In other embodiments, the extension portion may also extend horizontally or obliquely; those skilled in the art can select the extension direction of the connecting portion 321 according to actual needs.

[0062] The adjusting member 300 can rotate circumferentially along the inner ring burner cap 100 to change the overlapping area of ​​the adjusting hole 310 and the burner hole 210 in the radial direction of the inner ring burner cap 100. Based on the automatic adjustment of the adjusting plate 320 according to the gas power, the user can adjust the size of the adjusting hole 310 by rotating the adjusting member 300. When the user needs to adjust the burner hole 210, the adjusting member 300 can be rotated circumferentially along the inner ring burner cap 100, thereby changing the overlapping area of ​​the adjusting hole 310 and the burner hole 210 in the radial direction of the inner ring burner cap 100, that is, adjusting the area of ​​the adjusting hole 310 within the burner hole 210, thus adjusting the size of the burner hole 210. Furthermore, when the adjusting member 300 rotates, it can also dismantle the dirt accumulated in the burner hole 210, making the dirt particles smaller. When the adjusting member 300 is disassembled, it is easier for the dirt to flow out, making it easier to clean the burner hole 210.

[0063] At least some of the adjusting holes 310 and the flame holes 210 are positioned one-to-one in the circumferential direction of the adjusting member 300, thereby enabling the adjustment of the size of the multiple flame holes 210 in the circumferential direction of the inner ring flame cap 100. When the adjusting member 300 rotates, the relative positions of the multiple flame holes 210 and the adjusting holes 310 can be adjusted, making the adjustment of the size of the flame holes 210 more convenient.

[0064] In this embodiment, valve plates 322 are provided on only some of the adjustment holes 310. In other embodiments, valve plates 322 may be provided on all adjustment holes 310.

[0065] In this embodiment, the size of the adjusting hole 310 is smaller than the size of the flame hole 210, thereby allowing the adjusting plate 320 to be fully opened. In other embodiments, the size of the adjusting hole 310 may be set to be equal to the size of the flame hole 210. Those skilled in the art can select a suitable size for the adjusting hole 310 according to actual needs.

[0066] like Figure 7 As shown, the adjusting member 300 has a certain thickness in the radial direction of the inner ring flame cap 100. When the adjusting member 300 is rotated to the point where the adjusting hole 310 is misaligned with the flame hole 210, the inner wall of the placement groove 220 can limit the opening size of the adjusting piece 320. When the adjusting member 300 is rotated to the point where the adjusting hole 310 is misaligned with the flame hole 210, part of the adjusting hole 310 is located within the placement groove 220. The inner wall of the placement groove 220 limits the opening size of the adjusting piece 320, which in turn limits the size of the adjusting hole 310, allowing the user to adjust the size of the flame hole 210 by rotating the adjusting member 300.

[0067] In this embodiment, the adjusting member 300 surrounds the inner ring flame cap 100 circumferentially. In other embodiments, the adjusting member 300 may also be configured to be arranged in multiple segments at intervals along the circumference of the inner ring flame cap 100. Those skilled in the art can select a suitable specific structure for the adjusting member 300 according to actual needs.

[0068] In the radially inner to radially outer direction of the inner ring burner cap 100, the first hole segment 211 extends obliquely downward and the second hole segment 212 extends obliquely upward, so that the burner hole 210 is V-shaped as a whole. When dirt enters the burner hole 210, it will accumulate at the bottom of the V-shaped burner hole 210, and the adjusting member 300 is exactly at the bottom of the V-shaped burner hole 210. When the adjusting member 300 rotates, it can better clean the dirt accumulated at the bottom of the V-shaped burner hole 210 and reduce the blockage of the burner hole 210.

[0069] In this embodiment, the self-adjusting member 300 of the fire hole 210 extends obliquely upward to both sides. In other embodiments, the first hole segment 211 and the second hole segment 212 may also extend in other directions, and those skilled in the art can choose other suitable extension directions for the first hole segment 211 and the second hole segment 212.

[0070] The adjusting component 300 and the placement slot 220 extend vertically, making it easier for the user to place the adjusting component 300 into the placement slot 220. At the same time, when the adjusting component 300 is disassembled, it is easy for dirt in the fire hole 210 to flow out vertically. The vertically extending adjusting component 300 and placement slot 220 are also easier to manufacture.

[0071] In this embodiment, the adjusting member 300 and the placement groove 220 extend vertically. In other embodiments, the adjusting member 300 and the placement groove 220 may also be inclined. Those skilled in the art can select a suitable extension direction for the adjusting member 300 and the placement groove 220 according to actual needs.

[0072] The opening of the placement groove 220 is located at the lower end of the flame cap body 200. The adjusting member 300 is inserted into the placement groove 220 from the lower end of the flame cap body 200, thereby concealing the opening of the placement groove 220 and preventing the opening of the placement groove 220 from being exposed on the outside of the inner ring flame cap 100. It also facilitates the flow of dirt from the flame hole 210 out from the bottom of the inner ring flame cap 100 during cleaning, and also facilitates the installation and removal of the adjusting member 300.

[0073] The adjusting member 300 is also provided with a positioning member 400, which extends from the lower end of the adjusting member 300 toward the radially inward side of the adjusting member 300. The user can rotate the positioning member 400 to drive the adjusting member 300 to rotate, which makes it easier for the user to operate. At the same time, by observing the position of the positioning member 400, it is easier to determine the rotation angle of the adjusting member 300. By extending the positioning member 400 from the lower end of the adjusting member 300 toward the radially inward side of the adjusting member 300, it is easier for the user to rotate the positioning member 400 circumferentially along the inner ring fire cover 100.

[0074] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship of the device or element during normal use.

Therefore, they should not be construed as limiting this invention in this respect.

[0075] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
