Technical Field
[0001] The utility model relates to the technical field of heaters, in particular to an ignition device for a heater. Background Art
[0002] A heater is a device that increases the ambient temperature by converting energy. A heater increases the indoor temperature by converting electricity, gas or other fuels into heat. It is widely used in homes, offices and industrial sites. With the advancement of technology and the increase in people's demand for comfort, the design and function of heaters are also evolving. Different types of heaters have different heating mechanisms, which heat the air and allow it to circulate naturally, so that the room temperature rises evenly, such as electric fans and oil-filled radiator heaters; directly heat objects and people through infrared radiation, such as quartz tube heaters and halogen heaters; and gas heaters that use natural gas, liquefied petroleum gas or other fuels to generate heat through the combustion process. They have high heating efficiency and are especially suitable for larger spaces at a relatively low cost.
[0003] However, existing fuel heaters have certain defects. For example, the ignition device of most heaters uses a single ignition needle to ignite the fire hole of the burner, but the discharge distance of the ignition needle needs to be manually controlled and adjusted, and the controllability of the ignition quality is poor. In some high-end heaters, ignition and feedback are designed separately and wired independently, but the cost is higher than the former. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-Figure 2 As shown, it comprises a fixing plate 1, a nozzle fixing hole 11 is formed on the fixing plate 1, a primary air distribution hole 12 is formed outside the nozzle fixing hole 11, a secondary air distribution hole 13 is formed on the fixing plate 1 outside the primary air distribution hole 12, and a plurality of fixing installation holes 14 are formed on the fixing plate 1; a connecting pipe 2 is connected to one side of the fixing plate 1, the connecting pipe 2 is connected to a burner 3, and the connecting pipe 2 is arranged at the primary air distribution hole 12, a bracket 4 is provided on the burner 3, and an ignition assembly is provided on the bracket 4;
[0021] The ignition assembly includes a lead pin 7 mounted on one side of a bracket 4, an ignition pin 5 is mounted on the bracket 4 above the lead pin 7, the top of the ignition pin 5 and the top of the lead pin 7 are both bent, and the top of the ignition pin 5 is arranged opposite to the top of the lead pin 7; the rear end of the ignition pin 5 is connected to a pointed feedback head 6;
[0022] Insulating pads are provided at the installation locations of the feedback head 6 , the ignition needle 5 and the lead-in needle 7 on the bracket 4 .
[0023] The principle and use process of this utility model:
[0024] First, install the device in the fixed installation hole 14 by bolts, connect the fixing plate 1 to the air outlet of the fan used for combustion, install the nozzle required for combustion, connect the ignition needle 5 to the ignition circuit and the feedback circuit, and ground the lead needle 7, and then start working;
[0025] During ignition, the ignition needle 5 emits high voltage electricity, and an arc is generated between the lead-in needle 7 closest to the ignition needle 5, igniting the mixed gas of the combustible gas and oxygen. At the same time, the feedback head 6 and the ignition needle 5 detect the flame from both ends respectively. After the flame is generated, the ignition needle 5 or the feedback head 6 detects the flame and generates a feedback signal.
[0026] After the fan is started, air flows in from the primary air distribution holes 12 and the secondary air distribution holes 13 respectively. The air flow entering from the primary air distribution holes 12 will be sent to the burner 3 to mix with the combustible gas for combustion, while the air flow entering from the secondary air distribution holes 13 will be evenly divided and contact the burning flame from the outside of the burner 3. Part of the gas will participate in the combustion, thereby improving the combustion efficiency, and the other part of the gas will guide the flame from the outside and wrap the flame, thereby controlling the temperature of the heat exchanger.
