DETAILED DESCRIPTION

[0046] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0048] Reference Figure 1 As shown, a burner according to an embodiment of the present invention is applied to a gas cooker. The burner of this embodiment includes a burner assembly 1000 and a flame cover. The flame cover is mounted on the burner body 100 and has multiple flame holes. In related art, the ejector tube 200 of the burner assembly 1000 injects a mixture of gas and air into the mixing chamber of the burner body 100. The mixture is then transported through the mixing chamber to the corresponding flame holes in the flame cover. Finally, the mixture is ignited to form a flame, thereby achieving the heating function of the burner.

[0049] In traditional burners, the burner body 100 and the ejector tube 200 are generally made of cast iron sand casting or aluminum die casting, and the ejection port of the ejector tube 200 is an integral structure. In order to meet the requirements of burner assembly, there is a certain gap between the nozzle 310 and the ejection port. Therefore, there is a problem of eccentricity between the nozzle 310 and the ejector tube 200, which leads to reduced ejection performance and product performance problems. When the burner assembly 1000 is installed, the alignment process of the nozzle 310 and the ejector tube 200 is complicated and not easy to align, so the position needs to be adjusted repeatedly, and the assembly and adjustment are difficult. In addition, the position can only be adjusted manually, and automated installation cannot be achieved. The labor intensity is high and the assembly efficiency is low.

[0050] Reference Figure 1 and Figure 2As shown, the burner head assembly 1000 of the embodiment of the present invention includes a burner head body 100, an ejector pipe 200, and a control valve 300. When the burner head assembly 1000 of this embodiment is used for a two-ring burner, the burner head body 100 is generally provided with an outer ring gas mixing chamber 110 and an inner ring gas mixing chamber 120, the ejector pipe 200 includes an outer ring ejector pipe 260 and an inner ring ejector pipe 270, and the control valve 300 includes two nozzles 310. The outer ring ejector pipe 260 and the inner ring ejector pipe 270 are respectively connected to corresponding positions of the burner head body 100, the outer ring ejector pipe 260 is in communication with the outer ring gas mixing chamber 110, and the inner ring ejector pipe 270 is in communication with the inner ring gas mixing chamber 120, and the two nozzles 310 are respectively in communication with the air inlet end 210 of the outer ring ejector pipe 260 and the air inlet end 210 of the inner ring ejector pipe 270.

[0051] As another embodiment, when the burner head assembly 1000 of this embodiment is used for a single-ring burner, the burner head assembly 1000 includes a burner head body 100 having a gas mixing chamber, an ejector tube 200 and a control valve 300 having a nozzle 310, the ejector tube 200 is connected to the burner head body 100, and the nozzle 310 is connected to the air inlet end 210 of the ejector tube 200.

[0052] As other embodiments, it can be understood that the burner head assembly 1000 can also be a burner head assembly 1000 for a three-ring burner or more ring-level burners, and its structure can appropriately refer to the above two embodiments. In order to avoid repetition, it will not be described here.

[0053] Reference Figure 3 As shown, the burner assembly 1000 of the embodiment of the present invention further includes a connecting component 400. The connecting component 400 is used to securely mount the nozzle 310 to the air inlet end 210 of the ejector tube 200. The ejector tube 200 is provided with a mounting seat 220, and the connecting component 400 is connected to the mounting seat 220. It will be understood that the mounting seat 220 is located at the air inlet end 210 of the ejector tube 200. The mounting seat 220 can be integrally formed with the ejector tube 200 to achieve a fixed connection, such as by die-casting. Alternatively, the mounting seat 220 can be connected to the ejector tube 200 by other fastening methods, which are not specifically limited herein.

[0054] Reference Figure 4 As shown, the connecting component 400 includes a first connecting member 410 and a second connecting member 420 .

[0055] The first connecting member 410 and the second connecting member 420 are installed in steps. The first connecting member 410 can be detachably connected to the mounting base 220, and the second connecting member 420 can be detachably connected to the first connecting member 410 or the mounting base 220.

[0056] As another embodiment, the second connecting member 420 may be detachably connected to the mounting base 220 , and the first connecting member 410 may be detachably connected to the second connecting member 420 .

[0057] Reference Figure 5 and Figure 6 As shown, the first connecting member 410 and the second connecting member 420 cooperate to form a fixed structure 430. The fixed structure 430 is located at the air inlet end 210 of the ejector tube 200. The fixed structure 430 is used to position the nozzle 310. Therefore, the ejector tube does not need to adopt an ejection port assembly structure. It should be noted that when the burner head assembly 1000 is provided with two ejector tubes 200 and two nozzles 310, the connecting member 400 is formed with two fixed structures 430, which are respectively located at the air inlet ends 210 of the two ejector tubes 200. The two fixed structures 430 are respectively used to position the corresponding nozzles 310, thereby achieving stable connection and alignment of the two nozzles 310. The two fixed structures 430 are formed by the cooperation of the first connecting member 410 and the second connecting member 420. The first connecting member 410 of the two fixed structures 430 can be an integral structure, and the second connecting member 420 of the two fixed structures 430 can be an integral structure, thereby facilitating the positioning and installation of the nozzles 310. Of course, the two first connecting members 410 and the two second connecting members 420 may both be split structures, thereby forming two independent fixing structures 430 .

[0058] In addition, it can be understood that when the furnace head assembly 1000 is provided with an ejector tube 200 and a nozzle 310, the first connecting member 410 and the second connecting member 420 of the connecting component 400 cooperate to form a fixed structure 430 for positioning and installing the nozzle 310, thereby achieving stable connection and alignment of the nozzle 310.

[0059] Reference Figure 4 、 Figure 5 and Figure 6 As shown, it can be understood that the fixing structure 430 is formed as a fixing hole for the nozzle 310 to pass through, and the first connecting member 410 and the second connecting member 420 are respectively clamped on the outer wall of the nozzle 310, thereby fixing the nozzle 310 in the fixing hole. In this embodiment, by setting the installation positions of the first connecting member 410 and the second connecting member 420, the fixing structure 430 can better align the center of the nozzle 310 with the center of the ejection tube 200, that is, the center of the nozzle 310 coincides with the center of the ejection tube 200, which can improve the installation accuracy between the nozzle 310 and the ejection tube 200, thereby improving the ejection performance of the furnace head assembly 1000. In addition, as another embodiment, the fixing structure 430 can also be formed into a structure similar to a hole, for example, part of the inner wall abuts the outer wall of the nozzle 310, and the other part does not abut the outer wall of the nozzle 310 and is connected to the air inlet end 210 of the ejection tube 200. For example, referring to Figure 6As shown, the fixing structure 430 may be formed by two second connecting members 420 that are symmetrical in vertical direction, that is, the first connecting member 410 is constructed as a structure that is symmetrical in vertical direction with the second connecting member 420 .

[0060] Furthermore, the connecting member 400 adopts a structure in which the first connecting member 410 and the second connecting member 420 are installed separately. Therefore, one of the first connecting member 410 and the second connecting member 420 can be connected to the mounting base 220 first, and then the nozzle 310 can be installed. Finally, the other of the first connecting member 410 and the second connecting member 420 can be installed, thereby locking the nozzle 310 to the fixed structure 430 formed by the first connecting member 410 and the second connecting member 420. This can meet the requirements of automated installation of the burner head assembly 1000 and improve assembly efficiency. This avoids the problem of the complicated and difficult alignment process between the nozzle 310 and the ejector tube 200 during installation of the burner head assembly 1000 in related products, which requires repeated manual adjustment of the position.

[0061] Reference Figure 6 As shown, the first connecting member 410 and the second connecting member 420 can be connected along Figure 6 Arrange in the up and down direction, or along Figure 6 The first connecting member 410 and the second connecting member 420 lock the nozzle 310 to the mounting base 220 in the vertical direction or the horizontal direction, thereby improving the installation accuracy of the first connecting member 410 and the second connecting member 420, ensuring the centering accuracy of the nozzle 310 and the ejector tube 200, and improving the ejection performance of the furnace head assembly 1000.

[0062] Reference Figure 3 and Figure 4 As shown, a burner assembly 1000 according to one embodiment of the present invention includes two ejector tubes 200. These two ejector tubes 200 are spaced apart from each other, namely, an outer ring ejector tube 260 and an inner ring ejector tube 270. Mounting seats 220 are formed on the air inlet pipes of the outer ring ejector tube 260 and the air inlet ends 210 of the inner ring ejector tube 270. Mounting seats 220 are connected to the outer ring ejector tube 260 and the inner ring ejector tube 270.

[0063] Reference Figure 6 As shown, the first connecting member 410 is connected to the lower end of the mounting base 220, and the second connecting member 420 is connected to the upper end of the mounting base 220. The first connecting member 410 has two first connecting portions 411, which are respectively located at the air inlet end 210 of the outer ring ejector tube 260 and the air inlet end 210 of the inner ring ejector tube 270. The second connecting member 420 has two second connecting portions 421, which are respectively located at the air inlet end 210 of the outer ring ejector tube 260 and the air inlet end 210 of the inner ring ejector tube 270.

[0064] It is understood that the air inlet end 210 of the outer ring ejector tube 260 is provided with a fixing structure 430 formed by the cooperation of the first connecting portion 411 and the second connecting portion 421. The air inlet end 210 of the inner ring ejector tube 270 is also provided with a fixing structure 430 formed by the cooperation of the first connecting portion 411 and the second connecting portion 421. Therefore, the outer ring ejector tube 260 and the inner ring ejector tube 270 can each position and install the nozzle 310 through a fixing structure 430, thereby ensuring the centering accuracy of the nozzle 310 and the ejector tube 200, thereby improving the ejection performance of the furnace head assembly 1000.

[0065] Reference Figure 4 and Figure 6 As shown, it can be understood that the first connecting member 410 is further provided with a first mounting portion 412, and the first mounting portion 412 is connected to the mounting seat 220 through screws, and a screw hole is provided at the position of the mounting seat 220 that cooperates with the screw.

[0066] The first mounting portion 412 can also be fixedly connected to the mounting base 220 using fasteners such as rivets, so as to facilitate stable installation and matching between the first connector 410 and the mounting base 220. Of course, the first mounting portion 412 can also be fixedly connected to the mounting base 220 by means of clamping, welding, etc.

[0067] In this embodiment, the two first connection parts 411 are respectively connected to the two sides of the first mounting part 412 . The two first connection parts 411 and the first mounting part 412 are integrated into one piece, thereby achieving a stable connection between the first mounting part 412 and the mounting seat 220 .

[0068] To further improve the installation stability between the first connector 410 and the mounting base 220, one end of the first connector 411 connected to the first mounting portion 412 is positioned and connected to the mounting base 220. The first mounting portion 412 and the two first connectors 411 are respectively connected to the mounting base 220, thereby further improving the installation stability between the first connector 410 and the mounting base 220 and enhancing the assembly efficiency and accuracy of the first connector 410 and the mounting base 220.

[0069] Reference Figure 4 As shown, it can be understood that the two first connecting parts 411 are respectively provided with positioning holes 413, and correspondingly, the outer ring ejector tube 260 is provided with a positioning column 230 that is positioned and matched with the corresponding positioning hole 413, and the inner ring ejector tube 270 is provided with a positioning column 230 that is matched with the corresponding positioning hole 413.

[0070] This embodiment facilitates the positioning and installation of the first mounting portion 412 and the mounting seat 220, thereby improving the assembly efficiency of the first connecting member 410 and the mounting seat 220. It should be noted that, as another embodiment, the two first connecting portions 411 are each provided with a positioning post 230, and the outer ring ejector tube 260 and the inner ring ejector tube 270 are each provided with a positioning hole 413 corresponding to the positioning post 230. It is understood that the first connecting portion 411 and the ejector tube 200 can also be positioned in other ways, such as by positioning the first connecting portion 411 on the mounting seat 220, and the specific form is not limited here.

[0071] Reference Figure 6 As shown, it can be understood that the first connecting portion 411 is provided with a groove 414, the opening of which faces the second connecting portion 421. The bottom wall of the groove 414 is provided with a first curved portion 415, which fits against the outer wall of the nozzle 310, thereby wrapping the nozzle 310 within the groove 414, thereby achieving stable positioning of the nozzle 310, and further facilitating the second connecting portion 421 to accurately lock the installation position of the nozzle 310 when the second connecting member 420 is installed. It should be noted that the groove 414 is configured as a U-shaped groove, which facilitates guiding the nozzle 310 into the groove 414. Moreover, the U-shaped groove can wrap around half of the circumference of the outer wall of the nozzle 310, thereby better positioning the nozzle 310.

[0072] The second connecting portion 421 is provided with a second curved portion 423, which is in contact with the outer wall of the nozzle 310. The second curved portion 423 faces one end of the first connecting portion 411. The second curved portion 423 cooperates with the first curved portion 415 to achieve stable positioning of the nozzle 310, ensuring that the nozzle 310 is centered relative to the ejector tube 200, thereby improving the ejection effect of the burner head assembly 1000.

[0073] Reference Figure 4 and Figure 6 As shown, it can be understood that at least part of the second arc-shaped portion 423 is accommodated in the groove 414, which facilitates the introduction and installation of the second connecting portion 421 into the groove 414, so that the second arc-shaped portion 423 and the first arc-shaped portion 415 form a fixing structure 430 for positioning the nozzle 310. An installation gap is formed between the side wall of the second connecting portion 421 and the side wall of the groove 414, that is, there is a clearance fit between the two, which makes it easier to achieve automated assembly of the burner head assembly 1000. In this embodiment, the side wall of the second connecting portion 421 gradually tilts inward along the direction close to the second arc-shaped portion 423, that is, Figure 6 The inverted trapezoidal structure in the nozzle 310 makes it easier to introduce the second connecting portion 421 into the groove 414, thereby realizing the installation of the connecting component 400 and improving the assembly efficiency of the nozzle 310.

[0074] Reference Figure 6 As shown, it can be understood that the mounting seat 220 is provided with a first boss 221, and the first boss 221 is located above the first mounting portion 412. The first boss 221 can position the first mounting portion 412, so as to facilitate the alignment and installation of the first connecting member 410; and further restricts the movement of the first connecting member 410, so that the installation of the first connecting member 410 and the mounting seat 220 is more stable and reliable.

[0075] Reference Figure 4 and Figure 6 As shown, it will be understood that the second connector 420 also includes a second mounting portion 422. Two second connecting portions 421 are respectively connected to either side of the second mounting portion 422. The two second connecting portions 421 and the second mounting portion 422 are integrally formed. The second mounting portion 422 is fixedly connected to the first boss 221, thereby positioning the second connector 420 on the mounting base 220. The second mounting portion 422 is fixedly connected to the first boss 221 via fasteners such as screws, making installation more convenient and secure. It also facilitates vertical assembly of the second connector 420, improving the efficiency of automated assembly.

[0076] Reference Figure 4 As shown, it can be understood that a block 222 is provided on the side of the first boss 221 facing the second connector 420, and a slot 424 is provided on the side of the second mounting portion 422 facing the first boss 221. The block 222 and the slot 424 are positioned and matched, facilitating the alignment and installation of the second connector 420; and further restricting the movement of the second connector 420, making the installation of the second connector 420 and the mounting base 220 more stable and reliable. It should be noted that, as another embodiment, the second mounting portion 422 is provided with a block 222, and the first boss 221 is provided with a slot 424 that is positioned and matched with the block 222, which can also achieve the above effect.

[0077] Reference Figure 6 As shown, it can be understood that the second connecting member 420 is provided with a second boss 425 , and the second boss 425 is located between the second mounting portion 422 and the second connecting portion 421 .

[0078] There are two second bosses 425, and the two second bosses 425 are respectively positioned and connected with the corresponding first connecting parts 411 on the upper end surface of the groove 414, so that the second connecting member 420 and the first connecting member 410 are positioned and installed, making the structure of the connecting component 400 more stable and ensuring the installation accuracy of the nozzle 310.

[0079] Reference Figure 4 and Figure 6As shown, it is understood that first positioning bars 223 are respectively provided on both sides of the mounting base 220. The first positioning bars 223 can be formed by extending a portion of the outer wall of the ejector tube 200 in the direction toward the control valve 300. The first positioning bars 223 are positioned and connected to the upper end surface of the first connecting portion 411 located in the groove 414. The first positioning bars 223 are spaced apart from the first boss 221. The first positioning bars 223 can achieve positioning of the first connecting member 410, improving the efficiency of the alignment and installation of the first connecting member 410, and further limiting the degree of freedom of the first connecting member 410 in the upward direction, making the connection between the first connecting member 410 and the mounting base 220 more reliable.

[0080] Reference Figure 4 and Figure 6 As shown, it is understood that a second positioning bar 224 is provided on each side of the mounting base 220. The second positioning bar 224 can be formed by extending a portion of the outer wall of the ejector tube 200 toward the control valve 300. The two second positioning bars 224 are respectively connected to the two first connecting portions 411, thereby improving the alignment and installation efficiency of the first connecting member 410, thereby limiting the left-right freedom of the first connecting member 410, and making the connection between the first connecting member 410 and the mounting base 220 more reliable.

[0081] Reference Figures 1 to 6 As shown, when the burner head assembly 1000 of the embodiment of the present invention is assembled automatically, after the first connecting member 410 and the ejection tube 200 are installed, the burner head body 100 and the ejection tube 200 are first installed on the bottom shell of the stove (not shown in the figure), and then the control valve 300 is installed on the ejection tube 200 from top to bottom by a robot, and finally the second connecting member 420 is installed on the ejection tube 200, so that the nozzle 310 is installed in place, completing the assembly of the burner head assembly 1000.

[0082] As another embodiment, the first connecting member 410 and the second connecting member 420 are designed to be located opposite to the positions of the above embodiment, that is, the first connecting member 410 is located at the upper end of the mounting seat 220, and the second connecting member 420 is located at the lower end of the mounting seat 220.

[0083] At this time, when the furnace head assembly 1000 is assembled automatically, the control valve 300 can be installed first, and then the ejector tube 200 can be installed, while the installation steps of the first connecting member 410 and the second connecting member 420 remain unchanged.

[0084] As another embodiment, it is understood that the first connector 410 and the second connector 420 are detachably connected. The first connector 410 can be connected to the first mounting portion 412 of the second connector 420 via the second mounting portion 422, thereby achieving a detachable connection between the two. This embodiment has a similar function to the above embodiment of detachably connecting the second mounting portion 422 to the first boss 221. Both embodiments can lock the second connector 420 with the first connector 410 to securely connect the nozzle 310, thereby ensuring that the nozzle 310 is concentric with the ejector tube 200, thereby improving the ejection performance of the burner head assembly 1000. In addition, the second connector 410 can also be detachably connected to the first connector 410 through other methods, which are not limited to the specific embodiments herein.

[0085] Reference Figure 7 As shown, the ejector tube 200 and the burner body 100 are detachably connected. An air outlet 240 is provided at the end of the ejector tube 200 facing the burner body 100, and an air inlet 130 is provided at the end of the burner body 100 facing the ejector tube 200. The air outlet 240 of the ejector tube 200 is detachably connected to the air inlet 130 of the burner body 100. The air outlet 240 of the ejector tube 200 and the air inlet 130 of the burner body 100 can be connected by bolts, snap fasteners, rivets, or pins. With this design, if either the ejector tube 200 or the burner body 100 is damaged, the damaged component can be removed and replaced, reducing the maintenance cost of the burner assembly 1000.

[0086] A protrusion 241 extending along the circumferential direction of the gas outlet end 240 of the ejector tube 200 may be provided on the outer side wall thereof. The protrusion 241 may be embedded in the inner side wall of the gas inlet 130 of the burner body 100 .

[0087] When two ejector tubes 200 are provided, the inner diameter of the protrusion 241 of the outer ring ejector tube 260 is different from the inner diameter of the protrusion 241 of the inner ring ejector tube 270, thereby realizing a fool-proof design and avoiding the ejector tube 200 and the furnace head body 100 from being reversely installed.

[0088] A gasket 250 can be provided on the contact surface between the ejector tube 200 and the burner body 100 to provide a better sealing effect. The gasket 250 can be made of aluminum sheet or other metal. When the ejector tube 200 and the burner body 100 are press-fitted and assembled, the gasket 250 is squeezed and deformed, thereby sealing the contact surface between the end face of the gas outlet end 240 of the ejector tube 200 and the end face of the gas inlet 130 of the burner body 100. An adhesive layer, such as silicone adhesive, can also be provided on the contact surface between the ejector tube 200 and the burner body 100. This makes the sealing surface between the ejector tube 200 and the burner body 100 more airtight, and the service life of the burner assembly 1000 longer. In addition, the ejector tube 200 and the burner body 100 are manufactured separately, which makes the process mold simpler, assembly more convenient, and production cost lower.

[0089] Reference Figure 8 and Figure 9 As shown, it can be understood that the fixing structure 430 enables the nozzle 310 to be fixed to the ejector tube 200, and makes the axis of the nozzle 310 coincide with the axis of the ejector tube 200, so that the nozzle 310 and the ejector tube 200 are concentric, thereby improving the ejection performance of the furnace head assembly 1000.

[0090] Reference Figure 8 and Figure 9 As shown, the control valve 300 further includes a retaining ring 320, a damper spring 330, a damper plate 340, and an air regulating plate 350. A mounting groove 311 is defined on the outer wall of the nozzle 310, and the retaining ring 320 is mounted within the mounting groove 311. When assembling the control valve 300 with the ejector tube 200, the damper spring 330 is first compressed, and the damper plate 340 and the air regulating plate 350 are moved to a position behind the nozzle 310. After the nozzle 310 is inserted into the ejector tube 200, the damper spring 330 is released, and the damper plate 340 and the air regulating plate 350 are pressed against the end surface of the connecting component 400, i.e., the air inlet end 210 of the ejector tube 200, by the damper spring 330. The retaining ring 320 is used to limit the air regulating plate 350 and the air damper plate 340 from moving outward from the nozzle 310. The outer diameter of the retaining ring 320 is larger than the inner diameter of the air damper plate 340 and the inner diameter of the air regulating plate 350, which can constrain the air damper plate 340 and the air regulating plate 350 to move only on the nozzle 310 and not fall off from the nozzle 310.

[0091] The damper spring 330 is disposed on the side of the damper plate 350 facing away from the retaining ring 320. The damper spring 330 abuts against the damper plate 350 to apply a thrust to the damper plate 350, pressing the damper plate 350 and the damper plate 340 against the connecting component 400. This restricts the axial movement of the damper plate 350 along the nozzle 310, thereby securing the position. The damper plate 350, facing the retaining ring 320, maintains contact with the damper plate 340. The holes in the damper plate 350 cooperate with the holes in the damper plate 340 to adjust the damper opening, allowing the damper plate 350, in combination with the damper plate 340, to adjust the air volume.

[0092] Reference Figures 1 to 9 As shown, a burner according to one embodiment of the present invention includes a fire cover and a burner assembly 1000 according to the above embodiment, wherein the fire cover is mounted on the burner body 100.

The fixing structure 430 positions and locks the nozzle 310 of the control valve 300 to the air inlet end 210 of the ejector tube 200, thereby improving the installation accuracy between the nozzle 310 and the ejector tube 200, centering the nozzle 310 and the ejector tube 200 and improving the ejection performance of the burner assembly 1000. Furthermore, the use of a split connecting component 400 can meet the requirements of automated installation of the burner assembly 1000, thereby improving assembly efficiency.
