Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, and more specifically, to a split-type ignition mechanism. Background Technology

[0002] Driven by the market and the improvement of product functions, intelligent cooktops are becoming increasingly popular among consumers, and the requirements for the structure of the ignition needle used in cooktops are becoming more and more stringent.

[0003] The ignition needle of existing gas stoves is a one-piece structure. During installation, the entire ignition needle must first be connected to the burner head, and then the burner head is installed into the gas stove housing. When the ignition needle malfunctions and needs repair, the entire gas stove must be disassembled and the burner head removed before the ignition needle can be removed for repair or replacement. This has drawbacks such as complicated repairs and inconvenient cleaning operations. At the same time, there is also a risk of gas leakage when disassembling and reassembling the burner head to repair the ignition needle. Summary of the Invention

[0004] To overcome at least one of the defects in the prior art, this utility model provides a split ignition mechanism, which is divided into two parts that are detachably connected to the burner head. This facilitates installation, and the ignition assembly can be maintained without removing the burner head, reducing maintenance costs and avoiding the risk of leakage due to secondary disassembly and reassembly of the burner head.

[0005] This utility model provides a split ignition mechanism: including a base assembly and an ignition assembly. The base assembly is detachably connected to the lower end of the burner head, and the lower end of the base assembly is electrically connected to an igniter. The upper end of the base assembly extends into the mounting through hole of the burner head. The ignition assembly is detachably connected to the inner groove at the upper end of the burner head, and the lower end of the ignition assembly is inserted into the upper end of the base assembly to achieve circuit conduction.

[0006] Compared with the prior art, the split-type ignition mechanism of this utility model has the following advantages:

[0007] Compared to the traditional integrated ignition needle, the split ignition structure of this utility model comprises two independent parts: a base assembly and an ignition assembly. During installation, the base assembly is connected separately to the bottom of the burner head, while the ignition assembly is detachably connected to the inner cavity at the upper end of the burner head. After connection, the lower end of the ignition assembly and the upper end of the base assembly are inserted to achieve circuit conduction. The structure is simple and easy to install. Furthermore, in case of malfunction, there is no need to disassemble the burner head; the ignition assembly can be removed directly for repair or cleaning. This not only reduces the risk of leakage caused by repeated disassembly and reassembly of the burner head but also reduces the cost and labor costs of replacing the entire ignition component.

[0008] Furthermore, the base assembly includes a base body and a copper sleeve. The base body is connected to the lower end of the burner head. The middle part of the base body is provided with an upper and lower through mounting hole. The copper sleeve is inserted into the mounting hole. The lower end of the copper sleeve is connected to the igniter via an electric wire, and the upper end of the copper sleeve is electrically connected to the ignition assembly.

[0009] Furthermore, the ignition assembly includes a ceramic column, an ignition needle core, and a fixing sleeve. The ceramic column has an axially communicating insertion channel, and the ignition needle core is inserted into the insertion channel, with its lower end inserted into the inner hole at the upper end of the copper sleeve. The fixing sleeve is fitted over the ceramic column, and its lower end is detachably connected to the burner head. The outer wall of the ceramic column is also provided with a positioning step for axially limiting the fixing sleeve, thereby achieving the connection and positioning of the ceramic column and the burner head.

[0010] Furthermore, the fixing sleeve includes an external hexagonal connector, the lower end of which is provided with a connecting tube that fits into the mounting through hole. The outer wall of the connecting tube is formed with an external thread that screws into the mounting through hole, and the lower end face of the connecting tube abuts against the upper end face of the positioning step. In the above structure, the external hexagonal connector is easy to install, and the connection and fixation can be achieved using a suitable wrench.

[0011] As an improvement, the upper end of the external hexagonal connector is provided with a protective sleeve extending along the axial direction of the ceramic column. In the above improved structure, the ceramic mechanism is relatively brittle and easily broken; the protective sleeve serves to protect the ceramic column.

[0012] In a further improvement, the upper end of the base body is recessed with an annular positioning slot, and the lower end of the ceramic column is radially outer with an annular positioning tube. The lower end of the ignition needle core extends beyond the lower end face of the ceramic column. When the ceramic column and the base body are respectively connected to the upper and lower ends of the burner head, the positioning tube can be slidably inserted into the positioning slot, and the lower end of the ignition needle core is inserted into the upper end of the copper sleeve to achieve circuit conduction.

[0013] In a further improvement, the outer periphery of the base body is formed with at least two connecting lugs, each with a connecting hole through which a connecting screw for connecting to the burner head passes. In this improved structure, the base body is connected to the burner head via the connecting lugs, resulting in a simple structure and convenient installation.

[0014] In a further improvement, a positioning boss is formed protruding on the outer peripheral wall of the upper end of the ignition needle core, and the lower end face of the positioning boss abuts against the upper end face of the ceramic pillar. In the above improved structure, the positioning boss can position the vertical position of the ignition needle core, ensuring the structural stability after the ignition needle core and the ceramic pillar are assembled.

[0015] Other improvements and advantages of this invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and drawings. Attached Figure Description

Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0024] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] See Figures 1-4 As shown in the illustration, this application discloses a split-type ignition mechanism, mainly used in gas stoves. It includes a base assembly and an ignition assembly. The base assembly is detachably connected to the lower end of the burner head 1, and its lower end is electrically connected to the igniter. The upper end of the base assembly extends into the mounting through-hole 2 of the burner head 1. The ignition assembly is detachably connected to the recessed cavity at the upper end of the burner head 1, and its lower end is inserted into the upper end of the base assembly to achieve circuit conduction. In this structure, the traditional one-piece ignition needle structure is divided into two parts, which are detachably connected to the upper and lower ends of the burner head 1. When the ignition needle malfunctions and needs cleaning or replacement, it is not necessary to remove the entire burner head 1 structure; only the ignition assembly needs to be removed. This facilitates disassembly and assembly, saving manpower and material costs.

[0027] In this embodiment, see Appendix Figure 3 , 4 The base assembly includes a base body 3 and a copper sleeve 4. The base body 3 is connected to the lower end of the burner head 1. A vertically connected mounting hole is provided in the middle of the base body 3. The copper sleeve 4 is inserted into the mounting hole. The lower end of the copper sleeve 4 is connected to the igniter via an electrical wire, and the upper end of the copper sleeve 4 is electrically connected to the ignition assembly. Specifically, in the gas stove, the igniter is further electrically connected to a knob, and the knob controls the igniter to ignite the ignition needle.

[0028] More specifically, in the above structure, the ignition assembly includes a ceramic column 5, an ignition needle core 6, and a fixing sleeve 7. The ceramic column 5 is provided with an axially connected insertion channel. The ignition needle core 6 is inserted and fitted into the insertion channel, and the lower end of the ignition needle core 6 is inserted and fitted into the inner hole at the upper end of the copper sleeve 4 to achieve a conductive connection with the copper sleeve 4. In addition, the fixing sleeve 7 is fitted onto the outside of the ceramic column 5, and the lower end of the fixing sleeve 7 is detachably connected to the burner head 1. The outer wall of the ceramic column 5 is also provided with a positioning step 8 for axially limiting the fixing sleeve 7 to achieve the connection and positioning of the ceramic column 5 and the burner head 1.

[0029] In this embodiment, please continue to refer to the appendix. Figure 4The fixed sleeve 7 includes an external hexagonal connector 9. The lower end of the external hexagonal connector 9 is provided with a connecting pipe 10 that fits into the mounting through hole 2. The outer wall of the connecting pipe 10 is formed with an external thread that is helically engaged with the mounting through hole 2. The lower end face of the connecting pipe 10 abuts against the upper end face of the positioning step 8, thereby achieving axial positioning of the connection structure between the ceramic column 5 and the furnace head 1.

[0030] Furthermore, the upper end of the external hexagonal connector 9 is provided with a protective sleeve 11 extending along the axial direction of the ceramic column 5, which serves to protect the ceramic column 5. Preferably, the external hexagonal connector 9, the connecting tube 10, and the protective sleeve 11 are an integral structure, formed in one piece, reducing processing costs.

[0031] In addition, in this embodiment, an annular positioning slot 12 is recessed at the upper end of the base body 3, and an annular positioning tube 13 is formed on the radially outer side of the lower end of the ceramic column 5. The lower end of the ignition needle core 6 extends beyond the lower end surface of the ceramic column 5. When the ceramic column 5 and the base body 3 are respectively connected to the upper and lower ends of the burner head 1, the positioning tube 13 can be slidably inserted into the positioning slot 12, and the lower end of the ignition needle core 6 is inserted into the upper end of the copper sleeve 4 to achieve circuit conduction.

[0032] In other embodiments, a corresponding elastic element can be provided below the positioning slot 12. After the ignition assembly is installed, the lower end of the ceramic column 5 abuts against the elastic element, and the elastic force can provide a certain vertical tension to the threaded connection structure between the connecting pipe 10 and the mounting through hole 2, ensuring the stability of the connection structure. Furthermore, after the elastic element is provided, when disassembling the ignition assembly, after unscrewing the external hexagonal connector 9, the ignition assembly can pop up, making it easy to remove and improving replacement efficiency.

[0033] In this embodiment, participants are attached Figure 2 The detachable connection between the base body 3 and the burner head 1 specifically means that at least two connecting lugs 14 are formed on the outer periphery of the base body 3, and connecting holes 15 are provided on the connecting lugs 14. Each connecting hole 15 is fitted with a connecting screw (not shown in the figure) for connecting to the burner head 1. Preferably, the base body 3 is also made of ceramic material to provide insulation and avoid the risk of electric shock caused by leakage at the connection point between the ignition needle core 6 and the copper sleeve 4.

[0034] Additionally, a positioning boss 16 is formed protruding on the outer peripheral wall of the upper end of the ignition needle core 6. The lower end face of the positioning boss 16 abuts against the upper end face of the ceramic pillar 5 to ensure the structural stability of the ignition needle core 6 and the ceramic pillar 5 after they are assembled.

[0035] In other embodiments, the burner head structure can be arbitrarily replaced, for example, with... Figure 5 As shown.
