Description

Technical Field

[0001] The utility model relates to the technical field of igniters, in particular to a high-temperature resistant electric spark igniter. Background Technique

[0002] An igniter refers to a device that can provide sufficient energy in an instant to ignite pulverized coal, oil, gas, and fuel and can stabilize the flame. The ignition method of the igniter is electric spark ignition, which has a very wide range of applications.

[0003] There are still some problems in the use of existing electric spark igniters. First of all, especially at the output positions of the anode electric needle and the cathode electric needle, the high temperature is very likely to burn and damage the joints during long-term use. Generally, they are directly replaced, which not only has a low service life but also causes certain waste. Secondly, since the anode electric needle and the cathode electric needle generally use bolts to directly lock or are embedded and clamped, there are situations where disassembly and installation are inconvenient or the fixation is unstable, and the overall use effect is low.

[0004] Therefore, we propose a high-temperature resistant electric spark igniter to solve the above problems. Content of the Utility Model

An anode electric needle and a cathode electric needle are respectively arranged above and below the right side of the extension protection cylinder. An installation lock block is sleeved inside the right side of the extension protection cylinder outside the anode electric needle and the cathode electric needle. A plurality of groups of sliding grooves are evenly opened on the inner side of the installation lock block close to the anode electric needle and the cathode electric needle. Metal elastic sheets are arranged inside the plurality of groups of sliding grooves. The upper and lower ends of the metal elastic sheets are respectively connected with metal extrusion support sheets and metal extrusion gaskets. The top end of the metal extrusion support sheet is connected with a metal arc support cylinder. An annular installation through groove is opened inside the right side of the extension protection cylinder. The outer end of the metal arc support cylinder abuts against a top sheet inside the annular installation through groove. A plurality of groups of silica gel compression airbag tubes are installed between one side of the top sheet and one side close to the extension protection cylinder. Ventilation holes are all penetrated and opened on the mutually abutting surfaces of the metal arc support cylinder, the top sheet, the silica gel compression airbag tube, and the extension protection cylinder.

The top sheet is connected to multiple groups of silica gel compression airbag tubes, and the left and right end faces of the top sheet are slidably connected to both sides inside the annular installation through groove.

[0010] In a preferred example, the present utility model can be further configured as:

[0011] By adopting the above technical solution, a sealing gasket is embedded and installed between the other side of the top sheet and the outer end face of the metal arc support cylinder where they are in contact.

[0017] By adopting the above technical solution, a clamping block is embedded at the left end of the installation lock block inside the extension protection cylinder, and the inner extension ends of the anode electro-acupuncture needle and the cathode electro-acupuncture needle are embedded and clamped inside the clamping block.

[0018] In a preferred example, the present utility model can be further configured as:

[0019] By adopting the above technical solution, an installation connection sleeve column is sleeved on the outer side face at the contact position between the control grip and the extension protection cylinder, and a support adsorption pad is sleeved on the outer side face of the installation connection sleeve column.

It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0030] The following describes some embodiments of the present utility model with reference to the accompanying drawings to provide a high-temperature resistant spark ignition device.

[0031] Embodiment 1:

[0032] Combined with Figures 1 - 3 As shown, a high-temperature resistant electric spark igniter provided by the present utility model

[0033] Specifically, it includes a control grip 1. An extension protection cylinder 2 is installed at the right end of the control grip 1. An anode electric needle 4 and a cathode electric needle 5 are respectively arranged above and below the right side of the extension protection cylinder 2. An installation lock block 3 is sleeved inside the right side of the extension protection cylinder 2 outside the anode electric needle 4 and the cathode electric needle 5. A plurality of groups of sliding grooves 10 are evenly opened on the inner side of the installation lock block 3 close to the anode electric needle 4 and the cathode electric needle 5. Metal elastic sheets 11 are arranged inside the plurality of groups of sliding grooves 10. The upper and lower ends of the metal elastic sheets 11 are respectively connected with metal extrusion support sheets 18 and metal extrusion gaskets 17. The top end of the metal extrusion support sheet 18 is connected with a metal arc support cylinder 12. An annular installation through groove 8 is opened inside the right side of the extension protection cylinder 2. The outer end of the metal arc support cylinder 12 abuts against a top sheet 13 inside the annular installation through groove 8. A plurality of groups of silica gel compression air tube 14 are installed between one side of the top sheet 13 and one side close to the extension protection cylinder 2. Vent holes 15 are all penetrated and opened on the abutting surfaces of the metal arc support cylinder 12, the top sheet 13, the silica gel compression air tube 14 and the extension protection cylinder 2. The metal arc support cylinder 12, the top sheet 13, the silica gel compression air tube 14 and the extension protection cylinder 2 are communicated with each other through the vent holes 15. The top sheet 13 is connected with the plurality of groups of silica gel compression air tube 14. The left and right end faces of the top sheet 13 are slidably connected to both sides inside the annular installation through groove 8. A sealing gasket 16 is embedded and installed between the other side of the top sheet 13 and the outer end surface of the metal arc support cylinder 12. The sealing gasket 16 is mainly to enhance the sealing performance at the abutting part of the metal arc support cylinder 12 and the top sheet 13, and prevent external water vapor from seeping into the inside of the sliding groove 10 to damage the anode electric needle 4 and the cathode electric needle 5. The top end of the metal arc support cylinder 12 can penetrate and move inside the inner side of the extension protection cylinder 2 close to the installation lock block 3. The two side ends of the metal extrusion support sheet 18 are slidably clamped inside the sliding groove 10. The two extended ends at the top of the metal extrusion gasket 17 are slidably clamped inside the sliding groove 10, and the bottom end of the metal extrusion gasket 17 can be attached to one side of the anode electric needle 4 and the cathode electric needle 5. With the use of the above-mentioned various components, the heat conduction of the metal extrusion gasket 17 causes the metal elastic sheet 11 to produce a thermal expansion and contraction effect, so that the metal arc support cylinder 12 squeezes the top sheet 13 and makes the silica gel compression air tube 14 compress and expand, and discharges the heat guided inside the metal arc support cylinder 12 to the outside through the vent holes 15 for cooling, improving the overall high-temperature resistance effect, extending the service life and reducing waste.

[0034] Embodiment 2:

[0035] Combined with Figure 2 and Figure 3As shown, on the basis of the first embodiment,

[0036] Specifically, the left end of the installation lock block 3 is embedded inside the extended protection cylinder 2, and is provided with a clamping block 9. The clamping block 9 is mainly used to facilitate the clamping and fixing of the anode electro-acupuncture needle 4 and the cathode electro-acupuncture needle 5, and is electrically connected to the driving mechanism inside the extended protection cylinder 2 at the same time. The anode electro-acupuncture needle 4 and the cathode electro-acupuncture needle 5 are located at the extended end inside the installation lock block 3 and are embedded and clamped inside the clamping block 9. The use of the above-mentioned components and the components in the first embodiment, especially the elastic extrusion of the metal elastic sheet 11 on the metal arc support cylinder 12 and the metal extrusion gasket 17, when disassembling, the elastic contraction of the metal arc support cylinder 12 enables the installation lock block 13 to directly take out the anode electro-acupuncture needle 4 and the cathode electro-acupuncture needle 5 to the outside. At the same time, the metal extrusion gasket 17 also elastically extrudes and stabilizes the anode electro-acupuncture needle 4 and the cathode electro-acupuncture needle 5. While being convenient for disassembly and assembly, the stability of installation and use is improved.

[0037] Combined with Figure 1 and Figure 2 As shown, in the above embodiment,

[0038] Specifically, an installation connection sleeve column 6 is sleeved on the outer side of the abutting part of the control grip 1 and the extended protection cylinder 2. The installation connection sleeve column 6 is mainly used to facilitate the installation connection of the control grip 1 and the extended protection cylinder 2. A support adsorption pad 7 is sleeved on the outer side of the installation connection sleeve column 6. The support adsorption pad 7 mainly plays a role of adsorption and support stability when the igniter is not in use.

[0039] The working principle and usage process of the present utility model: First, when in use, when the user makes the anode electro-acupuncture needle 4 and the cathode electro-acupuncture needle 5 start to operate through an external control mechanism, the high temperature generated causes the metal elastic sheet 11 to have a thermal expansion and contraction effect through the heat conduction of the metal extrusion gasket 17, driving the metal extrusion support sheet 18 to make the metal arc support cylinder 12 extrude the top sheet 13 in the annular installation through groove 8 and compress and stretch the silica gel compression airbag tube 14. Finally, the heat guided inside the metal arc support cylinder 12 is discharged to the outside through the ventilation hole 15 to cool down the installation lock block 3. This not only improves the overall high-temperature resistance effect, but also improves the service life and reduces waste. Secondly, when in use, through the use of the above-mentioned components, especially the elastic extrusion of the metal arc support cylinder 12 by the metal elastic sheet 11, when disassembling, the elastic compression and relaxation of the metal arc support cylinder 12 enables the installation lock block 13 to directly take out the anode electro-acupuncture needle 4 and the cathode electro-acupuncture needle 5 to the outside. At the same time, the metal extrusion gasket 17 also plays a role of extrusion and stability for the anode electro-acupuncture needle 4 and the cathode electro-acupuncture needle 5 due to the elastic extrusion of the metal elastic sheet 11. In this way, while improving the convenience of disassembly and assembly, the stability of installation and use is also improved, and the use effect is improved.

[0040] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
