The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0043] In the related art, a gas stove generally includes a bottom plate and a panel. The bottom plate has a receiving cavity with one side open, and the panel can be disposed at the open portion to cover the receiving cavity. The burner head is fixed to the bottom plate and located in the receiving cavity. The panel has burner holes through which the burner head can be exposed. The gas distribution plate is fixedly connected to the stove body through the burner holes. The ignition device is fixed to the burner head and can extend into the central through hole of the gas distribution plate. The ignition device includes an ignition needle and a thermocouple. The ignition needle is used for ignition, and the thermocouple is used for flameout protection. Generally, the central through hole of the gas distribution plate can allow the central burner cap to pass through. The burner head transmits gas to the gas distribution plate. Part of the gas is mixed with air and then flows upward through the central through hole and is ejected from the gas outlet holes on the central burner cap. Part of the gas is mixed with air and then ejected from the gas outlet holes of the gas distribution plate. In this way, the ignition device is fixed to the burner head. When it is necessary to clean the burner head or replace the ignition device, it is necessary to remove the panel from the bottom plate, then disassemble the burner head, and finally remove the ignition device from the burner head to achieve the cleaning of the burner head and the replacement of the ignition device, which is time-consuming and laborious. Based on this, this application provides a burner head assembly.

[0044] Please refer to Figure 1 、 Figure 3 and Figure 4 In an embodiment of the present application, a burner assembly is provided, which includes a burner 100, a gas distribution plate 200, a center burner cap 700 and an ignition device 300. The gas distribution plate 200 is detachably mounted at one end of the burner 100 in the first direction. The gas distribution plate 200 has a central through hole 210 arranged along the first direction. The center burner cap 700 is mounted at the central through hole 210 of the gas distribution plate 200. The ignition device 300 is detachably mounted on the gas distribution plate 200 and is located between the outer periphery of the center burner cap 700 and the hole wall of the central through hole 210. One end of the ignition device 300 in the first direction is the working end and the other end is the wiring end. The working end is located on the side of the gas distribution plate 200 away from the burner 100, and the wiring end is located on the other side of the gas distribution plate 200.

[0045] In the above burner assembly, the gas distribution plate 200 and the burner 100 are detachably mounted together, and the ignition device 300 and the gas distribution plate 200 are detachably mounted together. When it is necessary to clean the gas stove panel 600, the user can detach the gas distribution plate 200 (together with the center burner cap 700) from the burner 100 and at the same time remove the ignition device 300, which is convenient for cleaning. When the ignition device 300 is damaged, after the user detaches the gas distribution plate 200 from the burner 100, the ignition device 300 is then detached from the gas distribution plate 200 and replaced. Compared with the prior art, when cleaning the gas stove, it is not necessary to disassemble the burner 100 and the gas stove panel 600. Only by removing the gas distribution plate 200 and the ignition device 300 is synchronously removed, the area around the burner 100 can be cleaned, and it is convenient to replace the ignition device 300.

[0046] Among them, the ignition device 300 may include an ignition needle 310 and / or a thermocouple 320. The ignition needle 310 is used to connect to a pulse circuit and release a pulse for ignition. The thermocouple 320 is used to control the valve action of the gas inlet pipeline in the gas stove after the flameout, so as to close the gas inlet pipeline in time and play a role in flameout protection. Among them, the working end of the ignition device 300 includes the working end of the ignition needle 310 and the working end of the thermocouple 320. The working end of the ignition needle 310 has a discharge body 311 capable of releasing a pulse. The working end of the thermocouple 320 has a detection part capable of detecting whether the flame is out. As for the detection principle of the detection part of the thermocouple 320, it can refer to the prior art and will not be elaborated here. The wiring end of the ignition device 300 includes the wiring end of the ignition needle 310 and the wiring end of the thermocouple 320. The wiring end of the ignition needle 310 is used to connect to the pulse circuit, and the wiring end of the thermocouple 320 is used to connect to the valve.

[0047] It should be explained that the outer ring wall of the central burner cap 700 has a plurality of air outlet holes. The ignition needle 310 of the ignition device 300 can ignite the gas flowing out through the air outlet holes of the central burner cap 700, and the thermocouple 320 of the ignition device 300 can detect the combustion condition of the flame near the central burner cap 700. It should be noted that the burner head assembly further includes an outer ring burner cap 800, which is assembled on the gas distribution plate 200, and the gas distributed by the gas distribution plate 200 flows out through the air outlet holes on the outer side wall of the outer ring burner cap 800. Figure 7 The structural schematic diagram of the assembled central burner cap 700, gas distribution plate 200 and outer ring burner cap 800 is shown. The assembly methods of the outer ring burner cap 800 and the central burner cap 700 with the gas distribution plate 200 can refer to the related technologies and will not be elaborated here.

[0048] Among them, the gas distribution plate 200 is detachably connected to the burner head 100. Specifically, the gas distribution plate 200 and the burner head 100 can be detachably connected by fasteners, such as screws, etc. Of course, other convenient detachable connection methods can also be used, which are not specifically limited.

[0049] In some embodiments, referring to Figure 6 and Figure 5 , the burner head assembly further includes a terminal block 400. The terminal block 400 and the burner head 100 are located on the same side of the gas distribution plate 200. The side of the terminal block 400 facing the gas distribution plate 200 has a connector, and the connector is detachably electrically connected to the wiring terminal of the ignition device 300 along the first direction.

[0050] During actual operation, the terminal block 400 is fixed in the accommodation cavity of the bottom plate 500. When the gas distribution plate 200 is removed from the burner head 100, during the process of removing the gas distribution plate 200 along the first direction, the wiring terminal of the ignition device 300 and the connector are gradually separated. When installing the gas distribution plate 200, when approaching the gas distribution plate 200 and the burner head 100 along the first direction, the wiring terminal of the ignition device 300 and the connector gradually approach and combine. In this way, by setting the terminal block 400 with a connector, during the disassembly and assembly of the separator, the wiring of the ignition device 300 or the disconnection of the ignition device 300 can be synchronously completed, simplifying the disassembly and assembly process and accelerating the disassembly and assembly process.

[0051] Specifically, the ignition device 300 includes the above-mentioned ignition needle 310 and thermocouple 320, and the connector includes a first connector 401 and a second connector 402. The first connector 401 is detachably connected to the terminal of the ignition needle 310 along a first direction, and the second connector 402 is detachably connected to the terminal of the thermocouple 320 along a first direction. The first connector 401 is used to connect the ignition needle 310 and the pulse circuit, and the second connector 402 is used to connect the thermocouple 320 and the valve member used to control the opening and closing of the air intake pipeline in the gas stove. At this time, in the process of removing the gas distribution plate 200 along the first direction, the terminal of the ignition needle 310 and the first connector 401 are gradually separated, and the terminal of the thermocouple 320 and the second connector 402 are gradually separated. When installing the gas distribution plate 200 and approaching the gas distribution plate 200 and the furnace head 100 along the first direction, the terminal of the ignition needle 310 and the first joint 401 gradually approach and combine, and the terminal of the thermocouple 320 and the second joint 402 gradually approach and combine.

[0052] Specifically, see Figure 4 , the wiring terminal of the ignition needle 310 has a first pair of joints 313, and the wiring terminal of the thermocouple 320 has a second pair of joints 321. The first pair of joints 313 and the first joint 401 are detachably connected along the first direction, and the second pair of joints 321 and the second joint 402 are detachably connected along the first direction. At this time, the first pair of joints 313, the second pair of joints 321, the first joint 401 and the second joint 402 are all rigid structures, which can be plugged in when the gas distribution plate 200 is installed on the furnace head 100, and can be separated when the gas distribution plate 200 is removed from the furnace head 100. It can be understood that the first pair of joints 313 and the first joint 401 are plugged in along the first direction, and the second pair of joints 321 and the second joint 402 are plugged in along the first direction.

[0053] Optionally, the terminal block 400 is fixed to the bottom shell of the gas stove by fasteners, such as being connected to the base by screws. In addition, the terminal block 400 also includes a first lead 403 and a second lead 404, the first lead 403 connects the pulse circuit and the first connector 401, and the second lead 404 connects the valve member and the second connector 402.

[0054] Further, see Figure 6 The furnace head 100 also has an avoidance hole 110 arranged parallel to the first direction, the wiring terminal of the ignition device 300 passes through the avoidance hole 110, and the wiring seat 400 is located on the side of the avoidance hole 101 away from the gas distribution plate 200. In this embodiment, the avoidance hole 110 for the power terminal of the ignition device 300 to pass through is provided on the furnace head 100, and the wiring seat 400 is located on the side of the avoidance hole 110 away from the gas distribution plate 200.

[0055] During actual installation, after the terminal of the ignition device 300 passes through the avoidance hole 110, it is connected to the first joint 401 and the second joint 402 on the wiring base 400. The setting of the avoidance hole 110 can play a certain guiding role for the terminal of the ignition device 300. At the same time, the wiring base 400 is located below the avoidance hole 110, that is, at least part of the wiring base 400 is received in the burner head 100, which helps to reduce the space of the accommodation cavity occupied by the burner head assembly and makes the structure of the burner head assembly more compact. Among them, the avoidance hole 110 may include two, corresponding to the first mounting hole 221 and the second mounting hole 222 respectively. Of course, it may also include only one, corresponding to the first mounting hole 221 and the second mounting hole 222 at the same time.

[0056] It should be noted that the setting of the above-mentioned wiring base 400 greatly facilitates the assembly of the burner head assembly. However, it does not limit that the burner head assembly must be provided with the above-mentioned wiring base 400. In other embodiments, other methods can also be adopted to facilitate the wiring and disconnection of the ignition device 300. For example, the joint connected to the ignition device 300 is fixed on the burner head 100. As the gas distribution plate 200 is installed or detached, the terminal of the ignition device 300 can be inserted into or separated from the joint. An operation port can also be opened on the panel 600, and the joint can be taken out from the operation port, and the joint can be manually connected to or disconnected from the ignition device 300.

[0057] In some embodiments, referring to Figure 3 , the gas distribution plate 200 includes a plate body and a mounting portion 220. The plate body has a central through hole 210. The mounting portion 220 protrudes from the hole wall of the central through hole 210 in a direction perpendicular to the first direction. The mounting portion 220 has a mounting hole detachably connected to the ignition device 300. At this time, the ignition device 300 is installed through the mounting hole, and the structure is simple, easy to process, and simplifies the structure of the gas distribution plate 200.

[0058] Specifically in the embodiment, referring to Figure 4 and Figure 5 , the ignition device 300 includes an ignition needle 310 and a thermocouple 320. Both the ignition needle 310 and the thermocouple 320 have a working end and a terminal. The mounting holes include a first mounting hole 221 and a second mounting hole 222. The ignition needle 310 is detachably installed in the first mounting hole 221, and the thermocouple 320 is detachably installed in the second mounting hole 222. At this time, the ignition needle 310 and the thermocouple 320 are separately installed, which is convenient for independent disassembly and replacement of the ignition needle 310 and the thermocouple 320 without affecting each other. Of course, in other embodiments, the ignition needle 310 and the thermocouple 320 can also be installed as a whole in one mounting hole.

[0059] Specifically in the embodiment, referring to Figure 5, the ignition pin 310 has an intermediate body 312 connecting its working end and its wiring end. The intermediate body 312 includes a main body 312a extending in a first direction and a limiting protrusion 312b protruding from the main body 312a in a direction perpendicular to the first direction. The main body 312a passes through the first mounting hole 221, and the limiting protrusion 312b abuts against the side of the gas distribution plate 200 facing away from the burner head 100. During actual installation, the main body 312a passes through the first mounting hole 221 from the side of the gas distribution plate 200 facing away from the burner head 100. When the limiting protrusion 312b abuts against the gas distribution plate 200, the ignition pin 310 is installed in place. It should be noted that the wiring end of the ignition pin 310 can freely pass through the first mounting hole 221 to realize the installation of the ignition pin 310. As for the size relationship between the working end of the ignition pin 310 and the first mounting hole 221, it is not limited. Preferably, the limiting protrusion 312b is annular, which helps to reduce the installation difficulty and simplify the installation process. Among them, the intermediate body 312 is an insulator, such as a ceramic body, which can play an insulating role between the gas distribution plate 200 and the working end, and between the working end and the wiring end, ensuring electrical safety.

[0060] Furthermore, the gas distribution plate 200 is coaxially provided with a limiting groove (not shown) corresponding to the first mounting hole 221, and the limiting protrusion 312b is matched with the limiting groove. At this time, the limiting protrusion 312b is limited in the limiting groove, and their sizes are matched. The centering of the ignition pin 310 during installation can be realized through the limiting protrusion 312b, so that the first docking head 313 of the ignition pin 310 and the first joint 401 can be smoothly docked and have good contact. Of course, in other embodiments, the smooth docking and good contact between the first docking head 313 and the first joint 401 can also be realized by the matching of the sizes of the main body 312a and the first mounting hole 221.

[0061] Furthermore, refer to Figure 4, the ignition pin 310 further includes a stopper 314 and an elastic member 315. The stopper 314 is detachably mounted on the body 312a and is located on the side of the gas distribution plate 200 close to the burner head 100. The elastic member 315 is sleeved on the body 312a and is limited between the gas distribution plate 200 and the stopper 314. The elastic member 315 is used to provide a pre-tightening force that presses the gas distribution plate 200 and the limit protrusion 312b against each other. When installing the ignition pin 310, after the body 312a is installed in place (i.e., the limit protrusion 312b abuts against the gas distribution plate 200), the elastic member 315 is sleeved onto the body 312a, and then the stopper 314 is installed on the body 312a. At this time, the elastic member 315 can generate a pre-tightening force under the limitation of the gas distribution plate 200 and the stopper 314. Under the action of this pre-tightening force, the gas distribution plate 200 and the limit protrusion 312b can be pressed against each other and remain in contact, so that the ignition pin 310 is stably connected to the gas distribution plate 200. When the ignition pin 310 needs to be replaced, first remove the stopper 314, then remove the elastic member 315, and finally take out the body 312a from the first mounting hole 221. In this embodiment, the retaining ring and the elastic member 315 are used in cooperation with the limit protrusion 312b to achieve the stable connection between the ignition pin 310 and the gas distribution plate 200, which not only ensures reliable connection but also facilitates the disassembly and assembly of the body 312a.

[0062] Further, referring to Figure 5 , the body 312a has an annular groove 312c recessed in a direction perpendicular to the first direction. The stopper 314 is sleeved in the annular groove 312c, and the outer ring wall of the stopper 314 protrudes compared to the outer wall of the body 312a. At this time, the stopper 314 is a retaining ring. The retaining ring is arranged in the annular groove 312c and protrudes from the body 312a. The elastic member 315 is limited between the retaining ring and the gas distribution plate 200. At this time, the retaining ring can effectively support the elastic member 315, thereby ensuring the connection reliability between the ignition pin 310 and the gas distribution plate 200. In other embodiments, a connection hole may also be provided on the body 312a in a direction perpendicular to the first direction. The stopper 314 is a stop rod, and the stop rod passes through the connection hole. At this time, the elastic member 315 can be supported by the part of the stop rod outside the connection hole.

[0063] Among them, the elastic member 315 is preferably a spring.

[0064] Of course, in other embodiments, other methods may also be adopted to stably connect the ignition pin 310 and the gas distribution plate 200. For example, the body 312a and the first mounting hole 221 are in clearance fit, or a locking nut is sleeved on the body 312a. The locking nut and the limit protrusion 312b are located on both sides of the gas distribution plate 200, and the body 312a and the gas distribution plate 200 are locked by the locking nut and the limit protrusion 312b.
