Abstract
Description
Technical Field
[0001] This utility model relates to the field of burner technology, and in particular to an internal flame spreader. Background Technology
[0002] In existing gas stoves, the burner holes of the internal burner are typically located on the side wall of the burner. During use, these holes are easily clogged by various types of dirt and grime, leading to ignition difficulties. When the burner holes are clogged, cleaning usually involves using a fine needle to poke them one by one, which is quite tedious. To prevent liquid overflow from clogging the burner holes, a cap can be installed on the upper part of the internal burner. However, if the cap is too small, its effect in preventing overflow is insufficient; if the cap is too large, it will affect the efficiency of the gas stove.
[0003] To address the issue of cleaning the burner holes, existing technologies employ a detachable first and second burner unit as the internal burner distributor. The first and second burner units are secured with fasteners, and the burner holes are formed by a combination of grooves on the first and second burner units. When the burner holes become clogged, the grooves are exposed by separating the first and second burner units, thus facilitating cleaning. However, securing the first and second burner units with fasteners makes it inconvenient to install and disassemble them. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defects of the first and second ignition units of the existing internal ignition device, which are inconvenient to install and disassemble, and to provide an internal ignition device.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] This utility model provides an internal flame divider, which is divided into a first flame divider unit and a second flame divider unit. The first flame divider unit is provided with a limiting member or a limiting hole, and the second flame divider unit is provided with a corresponding limiting hole or the limiting member. The first flame divider unit or the second flame divider unit is provided with a fixing member, and the limiting hole is provided on the fixing member.
[0007] The limiting member is elastic, and at least a portion of the limiting member can be compressed and inserted into the limiting hole in the vertical direction, and expand after passing through the limiting hole to lock the limiting member and the limiting hole.
[0008] In this solution, limiting members and limiting holes are respectively provided in the first and second ignition units. The limiting members are elastic, and at least a portion of the limiting members can be compressed vertically and inserted into the limiting holes, and then expand after exiting the limiting holes, thereby locking the limiting members and the limiting holes, allowing the first ignition unit to be installed onto the second ignition unit. Similarly, when the first and second ignition units are disassembled, the limiting members elastically deform and disengage from the limiting holes, thus separating the limiting members from the limiting holes. Compared to the prior art that connects the first and second ignition units with fasteners, this solution, through the cooperation of elastic limiting members and limiting holes, makes the installation and disassembly of the first and second ignition units more convenient.
[0009] Preferably, the limiting member includes a plurality of limiting portions, and the outer side of the projection of the plurality of limiting portions on the limiting hole can generate elastic deformation within the range from inside the limiting hole to outside the limiting hole.
[0010] In this solution, the limiting member achieves elastic deformation through multiple limiting parts. The outer side of the projection of the limiting part on the limiting hole can generate elastic deformation within the range from inside to outside the limiting hole, thereby allowing the limiting part to be compressed and inserted into the limiting hole, and then expand after passing through the limiting hole, thereby locking the limiting member and the limiting hole.
[0011] Preferably, the limiting portion is provided with a protrusion that protrudes outward from the limiting portion.
[0012] In this design, by providing an outwardly protruding protrusion on the limiting part, the limiting part is more easily compressed and deformed by the limiting hole when it is inserted into the limiting hole, making it easier for the limiting part to pass through the limiting hole. After the limiting part passes through the limiting hole and expands, the protrusion can provide partial support, enhancing the locking effect between the limiting part and the limiting hole, and further improving the reliability of the connection between the first and second ignition units.
[0013] Preferably, there are multiple limiting portions, and the lower end of each limiting portion is provided with an extension portion, the extension portions extending inward toward each other.
[0014] In this solution, by providing multiple extensions at the lower end of the limiting part, with the extensions extending inward towards each other, the gap between the lower ends of the multiple limiting parts can be reduced, preventing the fixing part from extending into the gap during insertion and causing misalignment between the limiting part and the limiting hole, thus further improving the ease of operation of inserting the limiting part into the limiting hole.
[0015] Preferably, the plurality of the extensions are staggered in the vertical direction.
[0016] In this solution, when the limiting part exits the limiting hole, the distance between the multiple limiting parts decreases due to compression, which can easily lead to interference between the multiple extensions. By staggering the multiple extensions in the vertical direction, interference between the multiple extensions can be avoided.
[0017] Preferably, the shape of the inner wall of the limiting hole and the shape of the limiting member are configured to restrict the relative rotation of the limiting member and the limiting hole in the circumferential direction of the inner fire distributor.
[0018] In this solution, by setting the shape of the inner wall of the limiting hole and the shape of the limiting member to restrict the relative rotation of the limiting member and the limiting hole in the circumferential direction of the inner flame distributor, the relative rotation of the first flame distributor unit and the second flame distributor unit in the circumferential direction can be avoided, making the connection between the first flame distributor unit and the second flame distributor unit more stable and preventing misalignment between the two.
[0019] Preferably, the first fire-distributing unit is provided with a limiting groove, and the shapes of the limiting groove and the limiting member are configured to restrict the relative rotation of the limiting member and the first fire-distributing unit in the circumferential direction of the inner fire-distributing device.
[0020] In this solution, by setting the shape of the limiting groove and the limiting member to restrict the relative rotation of the limiting member and the first fire distribution unit in the circumferential direction of the inner fire distribution unit, rotation between the limiting member and the first fire distribution unit is avoided, thus avoiding affecting the installation stability between the first fire distribution unit and the second fire distribution unit.
[0021] Preferably, the bottom surface of the first ignition unit is provided with a first groove, and the top surface of the second ignition unit is provided with a second groove, the first groove and the second groove combined to form a first flame hole;
[0022] The upper part of the first flame distribution unit is provided with a flow guide groove, and the first flame hole and the flow guide groove are aligned in the circumferential direction of the inner flame distributor;
[0023] The upper surface of the fastener is provided with a third groove, which communicates with the second groove, and the bottom surface of the third groove is aligned with the bottom surface of the second groove.
[0024] In this design, the upper part of the first flame distribution unit is provided with a guide groove, through which overflow liquid from above can flow downward. By aligning the first flame hole with the guide groove in the circumferential direction of the inner flame distribution unit and providing a third groove that communicates with the second groove, if overflow liquid flows from the guide groove into the first flame hole, the overflow liquid can flow to the third groove, thus preventing the overflow liquid from flowing into the inner side of the inner flame distribution unit.
[0025] Preferably, the fastener includes a first part and a second part, the first part being connected to the first fire distribution unit or the second fire distribution unit, and the second part being connected to the first part;
[0026] The width of the first part is smaller than the width of the second part.
[0027] In this solution, by setting the width of the first part to be smaller than the width of the second part, the obstruction of the fixing component at the air inlet of the fire hole can be reduced, thus preventing the fixing component from affecting the gas flow near the fire hole.
[0028] Preferably, the second part has a transition portion at one end near the first part, and the width of the transition portion gradually increases in the direction from near the first part to away from the first part.
[0029] In this design, the fastener is also provided with a transition section, which is located at one end of the second part near the first part. The width of the transition section gradually increases in the direction from near the first part to away from the first part, thereby further reducing the obstruction of the fire hole air inlet by the fastener.
[0030] The positive and progressive effects of this utility model are as follows:
[0031] By providing limiting members and limiting holes in the first and second ignition units respectively, the limiting members are elastic, and at least a portion of the limiting members can be compressed vertically and inserted into the limiting holes, then expand after exiting the limiting holes, thereby locking the limiting members and limiting holes, allowing the first ignition unit to be installed onto the second ignition unit. Similarly, when the first and second ignition units are disassembled, the limiting members elastically deform and disengage from the limiting holes, thus separating the limiting members from the limiting holes. Compared to the prior art that connects the first and second ignition units with fasteners, this solution, through the cooperation of elastic limiting members and limiting holes, makes the installation and disassembly of the first and second ignition units much more convenient.

[0061] Limiting groove 600 Detailed Implementation
[0062] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.
[0063] like Figures 1-6 As shown, this embodiment provides an internal flame divider 100, which is divided into a first flame divider unit 200 and a second flame divider unit 300. The bottom surface of the first flame divider unit 200 is provided with a plurality of upwardly recessed upper grooves 210, and the top surface of the second flame divider unit 300 is provided with a plurality of downwardly recessed lower grooves 310. The first flame divider unit 200 is detachably covered on top of the second flame divider unit 300, so that the plurality of upper grooves 210 and the plurality of lower grooves 310 are combined to form a plurality of flame holes 110.
[0064] The first ignition distribution unit 200 is provided with a limiting member 400 or a limiting hole 510, and the second ignition distribution unit 300 is provided with a corresponding limiting hole 510 or a limiting member 400. The first ignition distribution unit 200 or the second ignition distribution unit 300 is provided with a fixing member 500, and the limiting hole 510 is provided on the fixing member 500. The limiting member 400 is elastic, and at least a portion of the limiting member 400 can be compressed and inserted into the limiting hole 510 in the vertical direction, and expand after passing through the limiting hole 510 to lock the limiting member 400 and the limiting hole 510.
[0065] By providing a limiting member 400 and a limiting hole 510 in the first ignition unit 200 and the second ignition unit 300 respectively, the limiting member 400 is elastic, and at least a portion of the limiting member 400 can be compressed and inserted into the limiting hole 510 in the vertical direction, and expand after passing through the limiting hole 510, thereby locking the limiting member 400 and the limiting hole 510, so that the first ignition unit 200 can be installed onto the second ignition unit 300. Similarly, when the first ignition unit 200 and the second ignition unit 300 are disassembled, the limiting member 400 is elastically deformed and disengaged from the limiting hole 510, thereby separating the limiting member 400 and the limiting hole 510. Compared with the prior art that connects the first ignition unit 200 and the second ignition unit 300 by fastener 440, this solution uses the elastic limiting member 400 and the limiting hole 510 to make the installation and disassembly of the first ignition unit 200 and the second ignition unit 300 more convenient.
[0066] In this embodiment, the limiting member 400 is disposed in the first ignition distribution unit 200, and the fixing member 500 is disposed in the second ignition distribution unit 300. In other embodiments, the limiting member 400 may be disposed in the second ignition distribution unit 300, and the fixing member 500 may be disposed in the first ignition distribution unit 200.
[0067] The limiting member 400 includes a plurality of limiting portions 410. The outer side of the projection of the plurality of limiting portions 410 on the limiting hole 510 can generate elastic deformation within the range from inside to outside the limiting hole 510, thereby allowing the limiting portions 410 to be compressed and inserted into the limiting hole 510, and to expand after passing through the limiting hole 510, thereby locking the limiting member 400 and the limiting hole 510.
[0068] In this embodiment, there are two limiting parts 410, which are arranged opposite to each other, thereby making the structure of the limiting member 400 simpler and saving production materials. In other embodiments, the number of limiting parts 410 may be three or more, and those skilled in the art can select an appropriate number of limiting parts 410 according to actual needs.
[0069] The limiting member 400 also includes a connecting portion 430, to which the upper ends of the plurality of limiting portions 410 are connected. The connecting portion 430 is connected to the first ignition distribution unit 200, thereby facilitating the fixing of the plurality of limiting portions 410 and the connection of the limiting member 400 to the first ignition distribution unit 200. In this embodiment, the connecting portion 430 is fixed to the first ignition distribution unit 200 by a fastener 440. In other embodiments, other connection methods between the connecting portion 430 and the first ignition distribution unit 200 that are deemed suitable by those skilled in the art can also be selected.
[0070] In this embodiment, the limiting portion 410 extends vertically, making it easier for the limiting member 400 to be inserted vertically into the limiting hole 510. In other embodiments, the limiting portion 410 may also extend obliquely towards the inside or outside of the inner flame distributor 100.
[0071] The limiting part 410 is provided with a protrusion 411, which protrudes outward from the limiting part 410. When the limiting part 410 is inserted into the limiting hole 510, the limiting part 410 is more easily compressed and deformed by the limiting hole 510, and the limiting part 410 passes through the limiting hole 510 more easily. After the limiting member 400 passes through the limiting hole 510 and expands, the protrusion 411 can provide partial support, enhance the locking effect between the limiting member 400 and the limiting hole 510, and further improve the reliability of the connection between the first ignition unit 200 and the second ignition unit 300.
[0072] In this embodiment, the protrusion 411 is located at the middle of the extending direction of the limiting portion 410. In other embodiments, those skilled in the art may also choose other suitable specific positions of the protrusion 411 on the limiting portion 410.
[0073] In this embodiment, the outer surface of the protrusion 411 is arc-shaped, thereby reducing friction between the protrusion 411 and the fixing member 500, making it easier for the protrusion 411 to be inserted into the limiting hole 510. In other embodiments, the outer surface of the protrusion 411 may also be polygonal, or other shapes deemed suitable by those skilled in the art may be selected.
[0074] There are multiple limiting parts 410, and the lower end of each limiting part 410 is provided with an extension part 420. The extension parts 420 extend inward towards each other, thereby reducing the gap between the lower ends of the multiple limiting parts 410. This prevents the part of the fixing member 500 from extending into the gap during insertion, which would cause the limiting member 400 and the limiting hole 510 to be misaligned during installation, and further improves the ease of operation of inserting the limiting member 400 into the limiting hole 510.
[0075] like Figure 5 As shown, the multiple extensions 420 are staggered in the vertical direction. When the limiting part 410 exits the limiting hole 510, the multiple limiting parts 410 are compressed and the distance between them decreases, which can easily lead to interference between the multiple extensions 420. By staggering the multiple extensions 420 in the vertical direction, interference between the multiple extensions 420 can be avoided.
[0076] The shape of the inner wall of the limiting hole 510 and the shape of the limiting member 400 are set to restrict the relative rotation of the limiting member 400 and the limiting hole 510 in the circumferential direction of the inner flame divider 100, thereby preventing the first flame divider unit 200 and the second flame divider unit 300 from rotating relative to each other in the circumferential direction, making the connection between the first flame divider unit 200 and the second flame divider unit 300 more stable and preventing misalignment between the two.
[0077] like Figure 4 As shown, in this embodiment, the inner wall of the limiting hole 510 is rectangular, and the limiting part 410 of the limiting member 400 is two opposing sheet-like structures. The width of the two limiting parts 410 is equal to the side length of the two opposing sides of the rectangle, thereby preventing the limiting member 400 and the limiting hole 510 from rotating in the circumferential direction of the inner fire spreader 100.
[0078] In other embodiments, the inner wall of the limiting hole 510 can be hexagonal, and the limiting member 400 has three limiting portions 410, the width of each of the three limiting portions 410 being equal to the length of three mutually spaced sides of the hexagon. Those skilled in the art can also select appropriate shapes for the limiting member 400 and the limiting hole 510 according to actual needs.
[0079] like Figure 4 and Figure 6As shown, the first fire distribution unit 200 is provided with a limiting groove 600. The shape of the limiting groove 600 and the limiting member 400 is set to restrict the relative rotation of the limiting member 400 and the first fire distribution unit 200 in the circumferential direction of the inner fire distributor 100, thereby avoiding rotation between the limiting member 400 and the first fire distribution unit 200 and avoiding affecting the installation stability between the first fire distribution unit 200 and the second fire distribution unit 300.
[0080] In this embodiment, the limiting groove 600 is square, and the connecting portion 430 at the upper end of the limiting member 400 is also square, so the two can match each other. In other embodiments, the shapes of the limiting groove 600 and the upper end of the limiting member 400 can also be set as pentagons, or other shapes that are considered suitable by those skilled in the art can be selected.
[0081] like Figure 1 and Figure 3 As shown, the bottom surface of the first ignition distribution unit 200 is provided with a first groove 220, and the top surface of the second ignition distribution unit 300 is provided with a second groove 320. The first groove 220 and the second groove 320 combine to form a first flame hole 111. The upper part of the first ignition distribution unit 200 is provided with a guide groove 230, and the first flame hole 111 and the guide groove 230 are aligned in the circumferential direction of the inner ignition distributor 100. The upper surface of the fixing member 500 is provided with a third groove 520, which communicates with the second groove 320, and the bottom surface of the third groove 520 is aligned with the bottom surface of the second groove 320.
[0082] The upper part of the first flame distribution unit 200 is provided with a guide groove 230, through which overflow liquid from above can flow downward. By aligning the first flame hole 111 with the guide groove 230 in the circumferential direction of the inner flame distributor 100, and providing a third groove 520 that communicates with the second groove 320, if overflow liquid flows from the guide groove 230 into the first flame hole 111, the overflow liquid can flow to the third groove 520, thus preventing the overflow liquid from flowing into the inner side of the inner flame distributor 100.
[0083] In this embodiment, the bottom surfaces of the second groove 320 and the third groove 520 are configured to slope downwards towards the outer side of the inner ring flame cap, thereby facilitating the outflow of overflow liquid towards the outer side of the inner flame distributor 100. In other embodiments, the bottom surfaces of the second groove 320 and the third groove 520 may also be configured to extend horizontally.
[0084] like Figure 3As shown, the fixing member 500 includes a first part 530 and a second part 540. The first part 530 is connected to the first ignition unit 200 or the second ignition unit 300, and the second part 540 is connected to the first part 530. The width of the first part 530 is smaller than the width of the second part 540. By setting the width of the first part 530 to be smaller than the width of the second part 540, the obstruction of the fixing member 500 at the air inlet of the burner port 110 can be reduced, thus preventing the fixing member 500 from affecting the gas flow near the burner port 110.
[0085] In this embodiment, the fixing member 500 is disposed on the second ignition distribution unit 300, and the first part 530 is connected to the second ignition distribution unit 300. In other embodiments, the fixing member 500 may also be disposed on the first ignition distribution unit 200, and the first part 530 may be connected to the first ignition distribution unit 200.
[0086] The second part 540 has a transition portion 541 at one end near the first part 530. The width of the transition portion 541 gradually increases in the direction from near the first part 530 to away from the first part 530. The fixing member 500 also has a transition portion 541, which is located at one end of the second part 540 near the first part 530. The width of the transition portion 541 gradually increases in the direction from near the first part 530 to away from the first part 530, thereby further reducing the obstruction of the fixing member 500 to the air inlet of the fire hole 110.
