[0042] The invention provides a furnace head assembly.

[0043] In one embodiment of the present invention, Figures 1 to 3 As shown, the burner head assembly 300 includes a burner head body 301, a control valve and a connecting assembly. The burner head body 301 has an outer ring groove 302, an inner ring groove 303 and a central groove 304, the inner ring groove 303 is arranged around the central groove 304, the outer ring groove 302 is arranged around the inner ring groove 303, and the burner head body 301 is provided with an outer ring ejector pipe 305 communicating with the outer ring groove 302 and an inner ring ejector pipe 306 communicating with the inner ring groove 303. The control valve is provided with a valve body 311, an outer ring connecting pipe 312 and an inner ring connecting pipe 313. The valve body 311 has a valve cavity. The outer ring connecting pipe 312 and the inner ring connecting pipe 313 are both connected to the valve body 311, and the outer ring connecting pipe 312 and the inner ring connecting pipe 313 are both communicated with the valve cavity. The outer ring connecting pipe 312 is connected to the outer ring ejector pipe 305, and the inner ring connecting pipe 313 is connected to the inner ring ejector pipe 306, so that the outer ring connecting pipe 312 is communicated with the outer ring groove 302, and the inner ring connecting pipe 313 is communicated with the inner ring groove 303, that is, the valve cavity is communicated with the inner ring groove 303 and the outer ring groove 302. The connecting assembly is detachably connected to the valve body 311 and the furnace head body 301 to connect or disconnect the valve cavity with the center groove 304.

[0044] The technical solution of the present invention is to arrange an outer ring groove 302, an inner ring groove 303 and a center groove 304 on a burner body 301, wherein the inner ring groove 303 is arranged in an annular shape around the center groove 304, and the outer ring groove 302 is arranged in an annular shape around the inner ring groove 303; an outer ring ejector pipe 305 communicating with the outer ring groove 302 and an inner ring ejector pipe 306 communicating with the inner ring groove 303 are arranged on the burner body 301; and an outer ring connecting pipe 312 and an inner ring connecting pipe 313 are arranged on the control valve, wherein the outer ring connecting pipe 312 is connected to the outer ring ejector pipe 305, and the inner ring connecting pipe 313 is connected to the inner ring ejector pipe 306, so that the valve cavity is communicated with the outer ring groove 302 and the inner ring groove 303; and a connecting component is arranged, which is detachably connected to the valve body 311 and the burner body 301 by means of the connecting component, so as to connect or disconnect the valve cavity with the center groove 304. When the valve cavity is connected to the central groove 304, the valve cavity is connected to the central groove 304, the outer ring groove 302 and the inner ring groove 303 at the same time, thereby forming a three-ring gas stove; when the valve cavity is disconnected from the central groove 304, the valve cavity is only connected to the outer ring groove 302 and the inner ring groove 303, thereby forming a two-ring gas stove. The problem that the two-ring gas stove and the three-ring gas stove are each a separate platform and cannot share the platform is solved. In addition, since the connecting component is detachably connected to the valve body 311 and the burner body 301, the conversion between the two-ring gas stove and the three-ring gas stove is achieved by disassembling and assembling the connecting component, without changing the structure of the burner body 301 and the valve body 311. The structure of the burner body 301 and the valve body 311 is simple, the molding process is simple, and the defective rate is reduced, thereby reducing costs.

[0045] It can be understood that when the valve cavity is disconnected from the central groove 304, the gas in the valve cavity will not enter the central groove 304. At this time, the central groove 304 can be used as an air replenishing groove, that is, when gas is introduced into the gas stove for combustion, air is introduced through the central groove 304 to make the gas burn more completely, which not only saves gas but also reduces environmental pollution.

[0046] Reference Figure 2In one embodiment, the connection assembly includes a valve plugging member (not shown in the figure) and a central connecting pipe 321. The valve plugging member is used to be detachably connected to the valve body 311. One end of the central connecting pipe 321 is used to be detachably connected to the burner body 301, and the other end is used to be detachably connected to the valve body 311. When the valve plugging member is connected to the valve body 311, the valve cavity and the central groove 304 are disconnected, that is, the passage connecting the valve cavity and the central groove 304 is blocked by the valve plugging member, so that the gas passing through the valve cavity only enters the outer ring groove 302 through the outer ring connecting pipe 312, and enters the outer ring groove 302 through the inner ring connecting pipe 312. The pipe 313 enters the inner ring groove 303 but not the central groove 304, thus forming a two-ring gas stove; when one end of the central connecting pipe 321 is connected to the burner body 301 and the other end is connected to the valve body 311, the valve cavity is connected to the central groove 304, that is, the valve cavity is connected to the central groove 304 through the central connecting pipe 321, so that the gas passing through the valve cavity not only enters the outer ring groove 302 through the outer ring connecting pipe 312, enters the inner ring groove 303 through the inner ring connecting pipe 313, but also enters the central groove 304 through the central connecting pipe 321, thus forming a three-ring gas stove. The conversion method between the two-ring gas stove and the three-ring gas stove is simple and easy to operate.

[0047] In one embodiment, the connection assembly further includes a central ejector tube 331 disposed on the burner body 301, the central ejector tube 331 is connected to the central groove 304, and one end of the central ejector tube 331 away from the burner body 301 is used to connect to the central connecting tube 321. By providing the central ejector tube 331 to connect to the central connecting tube 321, the communication between the valve cavity and the central groove 304 is more convenient.

[0048] In one embodiment, one end of the central ejector tube 331 away from the burner body 301 is threadedly connected to the central connecting tube 321. The threaded connection makes the connection between the central ejector tube 331 and the central connecting tube 321 simpler, thereby making the conversion process between the three-ring gas stove and the two-ring gas stove more convenient and quick.

[0049] In one embodiment, the central groove 304 is set as a central hole that passes through from top to bottom, and a central installation position is set at the edge of the lower end of the central hole, and the central ejection tube 331 is detachably set at the central installation position. By setting the central groove 304 as a central hole that passes through from top to bottom, and setting the central ejection tube 331 at the central installation position at the lower end of the central hole, when the central ejection tube 331 is connected to the burner body 301, it is not necessary to open a channel on the side wall or bottom wall of the central groove 304, so that the central groove 304 and the central ejection tube 331 can be connected; and the central hole is set to pass through in the up and down direction, and the central ejection tube 331 is set at the lower end of the central opening, which is conducive to avoiding interference between the installation of the central ejection tube 331 on the burner body 301 and other parts, thereby simplifying the structure of the burner body 301.

[0050] Reference Figure 3 In one embodiment, a mounting lug 332 is provided at one end of the central ejector tube 331 close to the furnace head body 301, and the mounting lug 332 is used to connect to the central mounting position. By setting a mounting lug 332 at one end of the central ejector tube 331 close to the burner body 301, the central ejector tube 331 is installed in the central mounting position by using the mounting lug 332. On the one hand, the setting of the mounting lug 332 provides a fixed mounting position for the assembly between the central ejector tube 331 and the burner body 301, making it easier to disassemble and assemble the central ejector tube 331. On the other hand, the setting of the mounting lug 332 increases the contact area between the central ejector tube 331 and the central mounting position, making the assembly between the central ejector tube 331 and the burner body 301 more stable. In addition, the setting of the mounting lug 332 ensures that the assembly between the central ejector tube 331 and the burner body 301 will not damage the structure of the central ejector tube 331 itself, thereby reducing the probability of gas leakage caused by damage to the central ejector tube 331 and improving the safety of the gas stove.

[0051] In one embodiment, a first mounting hole is provided on the mounting lug 332, a second mounting hole is provided on the central mounting position, and the central ejector tube 331 is locked with the burner body 301 by a locking member passing through both the first mounting hole and the second mounting hole. The central ejector tube 331 is locked with the burner body 301 by passing through the first mounting hole and the second mounting hole, which is easy to operate and makes the disassembly and assembly process of the central ejector tube 331 simple and convenient.

[0052] In one embodiment, the first mounting hole and the second mounting hole are threaded holes, and the locking member is a screw or a bolt. The central ejector tube 331 is locked with the furnace head body 301 by using screws or bolts, which is convenient and quick to operate, and the screw or bolt locking method makes the central ejector tube 331 and the furnace head body 301 stably fixed.

[0053] Reference Figure 3In one embodiment, a positioning step 333 is provided on the periphery of the central ejection tube 331. The end of the central ejection tube 331 close to the burner body 301 is used to be inserted into the central hole, and the positioning step 333 is used to abut against the lower end of the central hole. By providing the positioning step 333 on the periphery of the central ejection tube 331, when the end of the central ejection tube 331 close to the burner body 301 is inserted into the central hole, the positioning step 333 abuts against the lower end of the central hole. On the one hand, the contact area between the central ejection tube 331 and the central hole is increased, making the installation of the central ejection tube 331 more stable. On the other hand, the connection sealing between the central ejection tube 331 and the burner body 301 is better, which is conducive to reducing the probability of gas leakage and improving the safety of the gas stove. Moreover, the positioning step 333 plays a positioning role in the process of assembling the central ejection tube 331 and the burner body 301, making the installation of the central ejection tube 331 more convenient.

[0054] In the above embodiment, the valve body 311 is provided with a valve connection port communicating with the valve cavity, and one end of the valve plugging member or the central connection pipe 321 for detachable connection with the valve body 311 is connected to the valve connection port. When a two-ring gas stove is required, the valve plugging member is connected to the valve connection port, so that the valve cavity is disconnected from the central groove 304, and the gas passing through the valve cavity does not enter the central groove 304, thereby forming a two-ring gas stove; when a three-ring gas stove is required, one end of the central connection pipe 321 for detachable connection with the valve body 311 is connected to the valve connection port, so that the valve cavity is connected with the central groove 304, so that the gas passing through the valve cavity can enter the central groove 304 through the central connection pipe 321, thereby forming a three-ring gas stove.

[0055] In one embodiment, the valve connection port is a threaded port, and one end of the valve plugging member or the central connecting pipe 321 for detachable connection with the valve body 311 is threadedly connected to the valve connection port. The valve plugging member or the central connecting pipe 321 is connected to the valve connection port by threaded connection, which facilitates the disassembly and assembly between the valve plugging member or the central connecting pipe 321 and the burner body 301, thereby making the conversion between the three-ring gas stove and the two-ring gas stove convenient and fast; and the threaded connection method can ensure the sealing of the connection while achieving rapid disassembly and assembly.

[0056] Reference Figure 2In one embodiment, the valve connection port is provided with a first adapter 314, and one end of the central connection pipe 321 for detachable connection with the valve body 311 is provided with a first connection nut 322, and the first connection nut 322 is threadedly connected to the first adapter 314. When the central connection pipe 321 and the valve body 311 are detachably connected by threaded connection, it is necessary to make the central connection pipe 321 and the valve body rotate relative to each other, and after the first adapter 314 and the first connection nut 322 are provided, it is only necessary to make the first adapter 314 and the first connection nut 322 rotate relative to each other, so that the connection between the central connection pipe 321 and the valve body 311 is more convenient.

[0057] In one embodiment, the air inlet of the central ejector tube 331 is provided with a second adapter 334, and one end of the central connecting tube 321 for detachable connection with the burner body 301 is provided with a second connecting nut 323, and the second connecting nut 323 is threadedly connected to the second adapter 334. The threaded connection between the second adapter 334 and the second connecting nut 323 is used to realize the detachable connection between the central ejector tube 331 and the burner body 301, which is convenient for disassembly and assembly and has good connection sealing.

[0058] In one embodiment, the outer ring ejector tube 305 is plugged into the outer ring connecting tube 312, and the inner ring ejector tube 306 is plugged into the inner ring connecting tube 313, so that the outer ring ejector tube 305 and the outer ring connecting tube 312 and the inner ring ejector tube 306 and the inner ring connecting tube 313 are easily connected. The specific plug-in structure can refer to the quick plug-in structure in the related art.

[0066] Among them, the center ring hole is connected with the center air channel 142, and the outside air passes through the interval air channel 141, the inner transverse air channel 143, the center air channel 142 and the inner ring hole in turn, and flows out from the outlet at the upper end of the inner ring hole to supplement the air for the combustion process of the inner ring fire and the center fire, thereby ensuring the gas flowing out of the center fire hole of the center cover 230 and the gas flowing out of the inner ring fire hole of the inner ring cover 220 are burned separately, thereby improving the problem of insufficient air supply that is prone to occur during the use of the three-ring gas stove.

[0067] In one embodiment, the secondary air passage also includes an outer lateral air passage 144 that passes through the outer ring gas passage 110 and connects the spacing air passage 141 with the outside air, so that the air around the burner 10 can flow from the outer lateral air passage 144 into the spacing air passage 141, and then flow to the middle of the burner 10, thereby replenishing air during the combustion process.

[0068] In one embodiment, a plurality of outer transverse air passages 144 are spaced apart in the circumferential direction of the outer ring gas passage 110 to increase the amount of supplementary outside air, so that sufficient air is provided during the gas combustion process. Specifically, the number of the outer transverse air passages 144 is greater than or equal to 2 and less than or equal to 10, such as 3, 4, 5, 6, 7, 8, etc.

[0069] In one embodiment, one of the multiple outer lateral air channels 144 is arranged corresponding to the inner lateral air channel 143, so as to facilitate the outside air entering the spacing air channel 141 from the outer lateral air channel 144 to flow into the inner lateral air channel 143, so as to improve the air supply efficiency.

[0070] In one embodiment, the outer transverse air passage 144 is gradually expanded in the radially outward direction, and / or the inner transverse air passage 143 is gradually expanded in the radially outward direction, so that the air inlet of the outer transverse air passage 144 and / or the inner transverse air passage 143 is larger, so that the outside air flows into the outer transverse air passage 144 and / or the inner transverse air passage 143.

[0071] In one embodiment, the inner ring wall of the inner ring gas channel 120 and the outer ring wall of the central gas channel 130 are the same ring wall, and the inner ring wall of the central gas channel 130 is used to form the side wall of the central air channel 142. By making the inner ring wall of the inner ring gas channel 120 and the outer ring wall of the central gas channel 130 the same ring wall, the distance between the inner ring gas channel 120 and the central gas channel 130 is reduced, which is beneficial to reducing the radial size of the gas distribution plate 100 on the one hand, and reducing the distance between the middle ring fire and the inner ring fire on the other hand, thereby improving the firepower of the middle part of the burner 10. In addition, by making the inner ring wall of the central gas channel 130 form the side wall of the central air channel 142, it is beneficial to reducing the radial size of the gas distribution plate 100 on the one hand, and facilitating the enlargement of the central through hole or the inner ring gas channel 120 on the other hand.
