Description

Technical Field

[0001] This utility model relates to a thermocouple and ignition needle mounting structure for an infrared burner. Background Technology

[0002] Currently, infrared burners on the market typically have their thermocouples and ignition needles positioned in the middle of the burner. The thermocouples and ignition needles are usually fixed to the infrared burner with screws, which results in low assembly efficiency and a large number of screws.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to propose a mounting structure for the thermocouple and ignition needle of an infrared burner, which can improve assembly efficiency.

[0005] To achieve the above objectives, this utility model provides a thermocouple and ignition needle installation structure for an infrared burner, which includes a burner body, a thermocouple, and an ignition needle. The burner body has an assembly hole in the middle, and the assembly hole has a snap-fit ​​interface and an installation hole. The thermocouple is snapped onto the snap-fit ​​interface, and the ignition needle is connected to the installation hole by a screw and abuts against the thermocouple to prevent the thermocouple from detaching from the snap-fit ​​interface.

[0006] In one or more embodiments, the surface of the thermocouple is provided with a threaded structure, a nut is screwed onto the thermocouple, the thermocouple is engaged with the locking interface by means of the nut, and the ignition needle abuts against the nut.

[0007] In one or more embodiments, the ignition needle is connected to a mounting plate, the mounting plate having holes corresponding to the mounting holes, and the ignition needle abuts against the nut with the help of the mounting plate.

[0008] In one or more embodiments, the thermocouple is screwed with two nuts, which can respectively abut against the upper and lower ends of the card interface. The card interface has a side opening through which the thermocouple can be connected to the card interface.

[0009] In one or more embodiments, the burner head body is provided with an outer annular gas chamber and an inner annular gas chamber, and the burner head body is provided with two ejector tubes that are respectively connected to the outer annular gas chamber and the inner annular gas chamber.

[0010] Compared with the prior art, the advantages of this utility model are: the thermocouple is installed by snap-fit, and the thermocouple is abutted by the installation of the ignition needle to prevent the thermocouple from coming out of the snap-fit ​​interface; therefore, this installation structure only uses screws to fix the ignition needle, while the thermocouple uses snap-fit, which has a higher installation efficiency, thereby greatly improving the assembly efficiency.

[0013] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0014] See appendix Figure 1-2 This application provides a thermocouple and ignition needle mounting structure for an infrared burner, comprising a burner body 1, a thermocouple 2, and an ignition needle 3. The burner body 1 has an outer annular gas chamber 11 and an inner annular gas chamber 12, and two ejector tubes 13 respectively connecting the outer annular gas chamber 11 and the inner annular gas chamber 12. An assembly hole 4 is located in the middle of the burner body 1, and the assembly hole 4 has a locking interface 5 and a mounting hole 6. The thermocouple 2 is snapped into the locking interface 5, and the ignition needle 3 is connected to the mounting hole 6 by a screw 7 and abuts against the thermocouple 2 to prevent the thermocouple 2 from detaching from the locking interface 5. During installation, the thermocouple is first snapped into the locking interface, and then the screw 7 is used to fix the ignition needle. Since the ignition needle abuts against the thermocouple, the thermocouple can be fixed using the ignition needle, improving assembly efficiency and reducing the use of screws.

[0015] The surface of the thermocouple 2 is provided with a threaded structure 8, and a nut 9 is screwed onto the thermocouple. The thermocouple 2 is engaged with the locking interface 5 by means of the nut 9. The ignition needle 3 holds the nut, and the user can adjust the height of the thermocouple sensing end by turning the nut.

[0016] The ignition needle 3 is connected to a mounting plate 10, which has holes corresponding to the mounting holes. The ignition needle 3 is held against the nut by the mounting plate 10, and the position of the thermocouple is fixed at the same time as the ignition needle is installed.

[0017] Two nuts 9 are screwed onto the thermocouple 2. The two nuts 9 can abut against the upper and lower ends of the card interface 5 respectively. The card interface 5 has a side opening. The thermocouple 2 can be connected to the card interface 5 through this opening. The thermocouple can be removed or installed through the side opening of the card interface. The two nuts can be used to adjust the height of the thermocouple sensing end.
