[0002] The existing cooktop burners can be divided into updraft burners and downdraft burners according to the injection mode of primary air. The primary air required by the updraft burner enters the injection pipe from above the cooktop table.

[0027] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] According to a first aspect of the present invention, a nozzle holder having a concealed ignition needle thermocouple structure is provided, such as Figures 1 to 5 As shown, the nozzle holder with a concealed ignition needle thermocouple structure is used in a burner. The nozzle holder with a concealed ignition needle thermocouple structure includes a nozzle holder body 1 and an ignition needle thermocouple assembly.

[0030] In the following description, reference will be made to Figures 1 to 5 The detailed structure of the nozzle seat body 1 and the ignition needle thermocouple assembly of the nozzle seat with the concealed ignition needle thermocouple structure is described in detail.

[0031] like Figure 1 and Figure 2 As shown, the nozzle holder with a concealed ignition needle thermocouple structure has a first state (transportation state) and a second state (installation and use state), and the nozzle holder with a concealed ignition needle thermocouple structure can switch between the first state and the second state.

[0032] like Figure 1 The diagram shown is a structural view of the nozzle holder with a concealed ignition needle thermocouple structure in its installed and used state. The ignition needle thermocouple assembly extends beyond the top of the nozzle holder body 1 for user convenience. Figures 2 to 4 The diagram shown is a structural diagram of the nozzle holder with a concealed ignition needle thermocouple structure in the transport state, with the ignition needle thermocouple assembly located inside the nozzle holder body 1.

[0033] In addition, see Figure 2 , Figure 3 and Figure 5 In the description of the embodiments, there are four directions: a first direction S1, a second direction S2, a third direction S3, and a fourth direction S4, wherein, as... Figure 3 and Figure 5 As shown, the first direction S1 is the overall height direction of the nozzle seat with the concealed ignition needle thermocouple structure, that is, the height direction of the nozzle seat body 1 and the ignition needle thermocouple assembly; as Figure 2 As shown, the second direction S2 is the length direction of the nozzle seat body 1; as Figure 5As shown, the third direction S3 is the width direction of the mounting base 201, and the fourth direction S4 is the length direction of the mounting base 201.

[0034] Specifically, a concealed cavity 101 is provided at the lower part of the nozzle seat body 1, and a mounting position 102 is provided at the top of the concealed cavity 101. During transportation, the ignition needle thermocouple assembly is housed within the concealed cavity 101; during installation and use, the ignition needle thermocouple assembly is installed at the mounting position 102. Thus, by integrating the thermocouple and ignition needle into a single ignition needle thermocouple assembly, it can be housed within the concealed cavity 101 during transportation, protecting the ignition needle thermocouple assembly and preventing breakage due to collisions with other structures during transport. After transportation, when the user needs to use it, the ignition needle thermocouple assembly is installed at the mounting position 102 of the nozzle seat body 1 for convenient subsequent use. Furthermore, since the ignition needle thermocouple assembly and the nozzle seat body 1 are detachably installed, subsequent maintenance and repair are facilitated. During maintenance, the cumbersome maintenance methods of the original structure are avoided, preventing structural leaks in the connecting pipes and nozzles, thus reducing safety risks.

[0035] Preferably, such as Figures 1 to 5 As shown, in this embodiment, the ignition needle thermocouple assembly may include a mounting base 201, an ignition needle 202, and a thermocouple 203, with the ignition needle 202 and thermocouple 203 disposed on the mounting base 201. Specifically, the shape of the mounting base 201 may correspond to the shape of the hidden cavity 101. In this embodiment, the hidden cavity 101 may be formed as an approximately cuboid chamber, and the mounting base 201 may also be formed as an approximately cuboid plate structure. The cuboid plate structure is convenient for installation and fixation due to its regular shape. However, it is not limited to this; the hidden cavity 101 may also be formed as a cube structure or a cylinder structure. The shape of the mounting base 201 matches the shape of the hidden cavity 101, allowing the mounting base 201 to be accommodated inside the hidden cavity 101. At the same time, the matching of these two elements also facilitates fixation during transportation, preventing the mounting base 201 from being impacted by external forces or bumps when inside the hidden cavity 101.

[0036] Preferably, the ignition needle 202 and the thermocouple 203 are arranged side by side in the mounting base 201 for easy installation.

[0037] Preferably, the dimensions of the ignition needle 202 and the thermocouple 203 in the first direction S1 are correspondingly set to the dimensions of the concealed cavity 101 in the first direction S1. Since both the ignition needle 202 and the thermocouple 203 are formed as approximately cylindrical structures with a certain length, in order to fully accommodate the ignition needle 202 and the thermocouple 203, the depth of the concealed cavity 101 (i.e., the dimension in the first direction S1) needs to correspond to the length of the ignition needle 202 and the thermocouple 203.

[0038] Preferably, such as Figures 1 to 5 As shown, in the embodiment, the top of the hidden cavity 101 is an opening, which is located on the upper surface of the nozzle seat body 1. The hidden cavity 101 can be regarded as a groove structure formed by the downward indentation of the upper surface of the nozzle seat body 1. The top of the groove structure is the opening, which facilitates the placement and removal of the ignition needle thermocouple assembly.

[0039] Mounting positions 102 are provided on both sides of the end of the opening in the second direction S2, i.e. Figure 2 As shown, the concealed cavity 101 can be formed as a cuboid-shaped groove structure. This cuboid-shaped groove structure has two ends in the second direction S2: one end away from the exhaust nozzle and the other end close to the exhaust nozzle. Mounting positions 102 are provided on both sides of the end away from the exhaust nozzle. From a top view, the mounting positions 102 and the concealed cavity 101 can form a convex shape. The shape and size of the mounting positions 102 can match the concealed cavity 101 and the ignition needle thermocouple assembly for easy installation. Preferably, the mounting positions 102 can be formed as groove structures, with the bottom of the groove slightly lower than the upper surface of the nozzle seat body 1. This allows the mounting base 201 to be directly aligned with the mounting positions 102 when installing the ignition needle thermocouple assembly, facilitating installation. Furthermore, in this embodiment, to ensure stable installation of the ignition needle thermocouple assembly and the nozzle seat body 1, two mounting positions 102 are provided, arranged opposite each other.

[0040] Preferably, such as Figures 1 to 5As shown, in this embodiment, the mounting base 201 has a first mounting hole 204, and the mounting position 102 has a second mounting hole 103. The ignition needle thermocouple assembly is detachably mounted to the mounting position 102 through the first mounting hole 204 and the second mounting hole 103. Specifically, both the first mounting hole 204 and the second mounting hole 103 can be formed as screw holes, and a detachable connection can be achieved by using screws. Preferably, there can be two first mounting holes 204, which are respectively opened at the two ends of the mounting base 201, specifically at the two ends in the fourth direction S4. Since the ignition needle 202 and the thermocouple 203 are arranged side by side in the mounting base 201, the four components—one first mounting hole 204, the ignition needle 202, the thermocouple 203, and the other first mounting hole 204—can be arranged in a row and arranged side by side in the mounting base 201. Each mounting position 102 is provided with a second mounting hole 103. In the embodiment, the two mounting positions 102 have two second mounting holes 103. The two second mounting holes 103 are set one-to-one with the two first mounting holes 204. In this way, during the assembly process, the mounting base 201 can be set in the mounting position 102 and connected to the mounting position 102 through the first mounting holes 204 set at both ends of the mounting base 201.

[0041] Preferably, such as Figures 1 to 5 As shown, in this embodiment, a third mounting hole 104 is provided at the bottom of the concealed cavity 101. During transportation, the ignition needle thermocouple assembly is detachably installed in the concealed cavity 101 through the cooperation of the first mounting hole 204 and the third mounting hole 104. Specifically, the number, location, and specifications of the third mounting holes 104 correspond to the first mounting holes 204 and the second mounting holes 103. For example, there can be two third mounting holes 104, and the distance between the two third mounting holes 104 is the same as the distance between the two first mounting holes 204. The third mounting holes 104 can be screw holes. Thus, during transportation, the ignition needle thermocouple assembly can be fixed inside the hidden cavity 101 through the third mounting hole 104, preventing the ignition needle thermocouple assembly from shifting or being bumped during transportation. In addition, before shipping, the third mounting hole 104 is detachably connected to the first mounting hole 204 by screws. Since the specifications of the first mounting hole 204, the second mounting hole 103, and the third mounting hole 104 are all the same, during installation, the screws of the third mounting hole 104 and the first mounting hole 204 can be removed, and the screws can be used to connect the first mounting hole 204 and the second mounting hole 103, avoiding the need for users to prepare additional screws during installation and making the installation process cumbersome.

[0042] Preferably, such as Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the ignition needle 202 is connected to the mounting base 201 via a first connector 205, which is located at the first end of the mounting base 201 in the third direction S3. The thermocouple 203 is connected to the mounting base 201 via a second connector 206, which is located at the second end of the mounting base 201 in the third direction S3. Since both the ignition needle 202 and the thermocouple 203 are formed as approximately cylindrical structural components with a certain length, additional connectors are needed for fixed connection to ensure stable installation of the ignition needle 202 and the thermocouple 203 with the mounting base 201. Therefore, the ignition needle 202 and the thermocouple 203 can be fixed via the first connector 205 and the second connector 206, respectively. The first connector 205 and the second connector 206 can be, for example, connecting screws.

[0043] Preferably, such as Figure 1 , Figure 2 and Figure 5 As shown, in the embodiment, since the ignition needle 202 and the thermocouple 203 are connected to the mounting base 201 through the first connector 205 and the second connector 206, the side of the mounting base 201 (i.e., the two ends on the third direction S3) will have the ends of the connectors protruding outward. Therefore, in order to realize that the ignition needle thermocouple assembly is accommodated inside the hidden cavity 101, the width of the hidden cavity 101 needs to correspond to the width of the ignition needle thermocouple assembly with the connectors, so as to facilitate the accommodation.

[0044] Preferably, such as Figure 3 As shown, in the embodiment, the end of the ignition needle 202 in the first direction S1 passes through the mounting base 201, and a locking position is formed on the periphery of the end of the ignition needle 202 in the first direction S1; the ignition needle thermocouple assembly may also include a fixing piece 207, the first end of the fixing piece 207 in the first direction S1 is disposed on the side of the mounting base 201 in the fourth direction S4, the first connector 205 passes through the fixing piece 207 and the mounting base 201 along the third direction S3 and is connected to the ignition needle 202, and the second end 2071 of the fixing piece 207 in the first direction S1 is locked in the locking position. The length of the ignition needle 202 is longer than that of the thermocouple 203, and the diameter of the near-cylinder is also larger. Therefore, a fixing plate 207 is needed to reinforce the ignition needle 202 during installation. The end of the ignition needle 202 may include a protruding block that protrudes outward along the axial direction. The diameter of the protruding block is smaller than the diameter of the main body of the ignition needle 202. Therefore, a locking position is formed at the connection between the protruding block and the main body of the ignition needle 202. The fixing plate 207 can be formed into an L-shaped plate structure. One end of the L-shaped plate structure can be close to the side of the ignition needle 202, and the other end can abut against the locking position, thereby forming a locking connection between the fixing plate 207 and the ignition needle 202. Finally, the fixing plate 207 and the ignition needle 202 are fixedly connected through the first connector 205.

[0045] Preferably, such as Figure 3 and Figure 4 As shown, in this embodiment, the nozzle holder with a concealed ignition needle thermocouple structure may include a mounting plate 3, which is fastened to the concealed cavity 101. The mounting plate 3 has a limiting groove 301 on the side facing the ignition needle thermocouple assembly in the first direction S1. The limiting groove 301 is provided corresponding to the ignition needle 202 and the thermocouple 203. The limiting groove 301 is used to limit the ends of the ignition needle 202 and the thermocouple 203, preventing shaking and collisions caused by the lack of height limitation on the ignition needle 202 and the thermocouple 203. In the transport state, the mounting plate 3 is fastened to the concealed cavity 101, sealing the opening of the concealed cavity 101 to prevent dust and other contaminants from entering the interior of the concealed cavity 101, thus protecting the ignition needle thermocouple assembly.

[0046] Preferably, such as Figure 3 and Figure 4 As shown, in this embodiment, the size of the mounting plate 3 is larger than the sum of the sizes of the concealed cavity 101 and the mounting position 102. Specifically, since the opening of the concealed cavity 101 and the mounting position 102 can be formed into a U-shaped structure when viewed from above, the mounting plate 3 can be formed into an approximately cubic plate structure to seal the opening of the concealed cavity 101 and the mounting position 102. Preferably, the side of the mounting plate 3 facing the opening of the concealed cavity 101 can extend downward to form a boss structure, the shape and size of which correspond to the aforementioned U-shaped structure. Thus, when the mounting plate 3 covers the opening of the concealed cavity 101 and the mounting position 102, the boss structure can interlock with the U-shaped structure. Furthermore, for sealing, a sealing gasket or sealant can be provided on the periphery of the boss structure.

[0047] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, a mounting bracket 4 is provided on the side of the nozzle seat body 1. The dimension of the mounting bracket 4 in the first direction S1 is larger than the dimension of the hidden cavity 101 in the first direction S1. Specifically, the mounting bracket 4 enables the overall installation of the nozzle seat body 1. To avoid interference during overall installation, the height of the mounting bracket 4 needs to be greater than the height of the hidden cavity 101. Preferably, there are multiple mounting brackets 4, which are evenly arranged on the lower side of the nozzle seat body 1.

[0048] Preferably, such as Figures 1 to 4As shown, in this embodiment, the ignition needle thermocouple assembly is disposed at one end of the nozzle seat body 1. The other end of the nozzle seat body 1 is also provided with an outer ring air inlet nozzle 5, an inner ring air inlet nozzle 6, an outer ring air outlet nozzle 7, and an inner ring air outlet nozzle 8. The outer ring air inlet nozzle 5 and the inner ring air inlet nozzle 6 are disposed at the bottom of the other end of the nozzle seat body 1, and the outer ring air outlet nozzle 7 and the inner ring air outlet nozzle 8 are disposed at the top of the other end of the nozzle seat body 1. The outer ring air inlet nozzle 5 and the inner ring air inlet nozzle 6 can both be connected to a gas pipe and supply gas to the outer ring gas chamber and the inner ring gas chamber respectively. The outer ring air outlet nozzle 7 and the inner ring air outlet nozzle 8 can supply gas to the outer ring flame and the inner ring flame respectively.

[0049] The assembly and use process of this nozzle holder with a concealed ignition needle thermocouple structure is as follows: Figures 2 to 4 As shown, after the nozzle holder with the concealed ignition needle thermocouple structure is manufactured, the ignition needle thermocouple assembly is located inside the concealed cavity 101 of the nozzle holder body 1. Simultaneously, the mounting base 201 of the ignition needle thermocouple assembly is connected to the third mounting hole 104 of the concealed cavity 101 via the first mounting hole 204, using detachable connecting screws. With the ignition needle thermocouple assembly located inside the concealed cavity 101 of the nozzle holder body 1, the top of the concealed cavity 101 is sealed using a mounting plate 3. The limiting groove 301 of the mounting plate 3 can limit the movement of the ignition needle 202 and the thermocouple 203. After transportation, the user first opens the mounting plate 3, removes the connecting screws, takes out the ignition needle thermocouple assembly, then aligns the mounting base 201 of the ignition needle thermocouple assembly with the mounting position 102, and connects and fixes the first mounting holes 204 and the second mounting holes 103 using connecting screws to complete the installation. Figure 1 As shown.

[0050] This nozzle holder with a concealed ignition needle thermocouple structure allows for the detachable installation of the ignition needle thermocouple assembly onto the nozzle holder body through the cooperation of the ignition needle thermocouple assembly and the nozzle holder body. It also has two states: transportation and use. This is beneficial for protecting the long thermocouple and igniter from damage during transportation. At the same time, by installing the ignition needle and thermocouple on the mounting base, maintenance and disassembly are facilitated, avoiding the safety hazards caused by gas leakage when disassembling and assembling the nozzle holder body.

[0051] Furthermore, according to a second aspect of the present invention, a burner is provided, the burner comprising a nozzle holder having a concealed ignition needle thermocouple structure as described above. This burner can be mounted at the desired location using a mounting bracket 4, and because it uses a nozzle holder with a concealed ignition needle thermocouple structure, it facilitates cleaning and subsequent maintenance by the user.

[0052] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
