Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stoves, in particular to a burner. Background Art
[0002] When the burner is in use, the overflow will flow to the tail of the ignition needle, which can easily cause the tail of the ignition needle to discharge to the base, causing the head of the ignition needle to discharge poorly, such as no discharge or intermittent discharge, which can lead to ignition failure and other problems. The current solution is usually to strengthen the insulation at the tail of the ignition needle, such as setting a silicone insulating sleeve at the connection position between the tail of the ignition needle and the wire. However, in a high temperature environment, the insulating sleeve is prone to aging and damage. Since the wire and the insulating sleeve are flexible parts, they are easy to touch the high-temperature base wall, causing damage to the insulating sleeve or the wire. The overflow will also accelerate the aging and damage of the insulating sleeve, causing the insulating sleeve to fail, which makes the tail of the ignition needle easy to discharge to the nearby base, wasting electricity, resulting in a decrease in the number of discharge sparks from the ignition needle to the fire cover, a decrease in the energy of the electric sparks, or no discharge at all, intermittent discharge, etc., which can lead to problems such as failure to ignite or difficulty in ignition, making the stove unable to use normally. Utility Model Content

[0051] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the following examples.
[0052] like Figure 1-Figure 5 As shown, this embodiment provides a burner, which includes an ignition needle assembly 100, a hard protective sleeve 200, and a flexible protective sleeve 300. The ignition needle assembly 100 includes a needle body 110, an insulator 120, and a wire 140. The insulator 120 is arranged on the outer periphery of the needle body 110, the wire 140 is connected to the lower end of the needle body 110, and the flexible protective sleeve 300 is sleeved on the outer periphery of the wire 140. The hard protective sleeve 200 is sleeved at the connection between the needle body 110 and the wire 140, and is sleeved on the outer periphery of the flexible protective sleeve 300, which can better prevent overflow from flowing to the tail of the ignition needle assembly 100. When overflow flows down, the hard protective sleeve 200 has a drainage function, preventing the overflow from entering the flexible protective sleeve 300 inside, effectively isolating the overflow. The outer protective cover is set to be hard, so that the protective cover is not easily damaged. The hard protective cover 200 has a guiding function, which can prevent the protective cover or the wire 140 from hitting the wall of the base 500 of the burner, avoid high temperature damage to the protective cover or the wire 140, avoid the problem of power loss at the tail of the ignition needle, and improve the ignition effect of the burner.
[0053] The burner also includes a base 500 and a mixing chamber 400. The mixing chamber 400 is arranged above the base 500. A first mounting hole 410 is provided on the mixing chamber 400. A second mounting hole 510 is provided on the base 500. The ignition needle assembly 100 is provided in the first mounting hole 410 and the second mounting hole 510, so as to fix the ignition needle assembly 100 on the mixing chamber 400 and the base 500. An annular boss 420 is provided on the first mounting hole 410. The annular boss 420 can block overflow from above and prevent overflow from flowing to the tail of the ignition needle assembly 100, thereby improving the discharge problem at the tail of the ignition needle assembly 100 and improving the ignition effect of the burner.
[0054] A waterproof ring 430 is provided above the annular boss 420, and the outer peripheral side of the ignition needle assembly 100 fits with the inner side of the waterproof ring 430, thereby better blocking the overflow from above and preventing the overflow from flowing to the tail of the ignition needle assembly 100, thereby improving the discharge problem at the tail of the ignition needle assembly 100 and enhancing the ignition effect of the burner.
[0055] A first step 520 is provided on the second mounting hole 510, and a protrusion 121 having a shape matching that of the first step 520 is provided on the insulator 120. Protrusion 121 is provided on the first step 520. By providing protrusion 121 on the first step 520, on the one hand, the height position of the ignition needle assembly 100 can be limited, so that the ignition distance between the needle head of the ignition needle assembly 100 and the ignition cover remains unchanged, that is, the optimal ignition distance is not affected, thereby enhancing the ignition effect. On the other hand, if overflow flows into the second mounting hole 510, protrusion 121 can also prevent the overflow from flowing into the rear end of the ignition needle assembly 100 below, thereby improving the discharge problem at the rear end of the ignition needle assembly 100 and improving the ignition effect of the burner.
[0056] The protrusion 121 is arranged around the circumference of the ignition needle assembly 100, which can provide all-round protection, thereby better blocking the overflow from above, preventing the overflow from flowing to the tail of the ignition needle assembly 100, improving the discharge problem at the tail of the ignition needle assembly 100, and improving the ignition effect of the burner.
[0057] An annular groove 122 is provided below the protrusion 121, and a sealing ring 130 is provided on the annular groove 122. The sealing ring 130 can further block the overflow from above and prevent the overflow from flowing to the tail of the ignition needle assembly 100. At the same time, the ignition needle assembly 100 and the sealing ring 130 can be assembled into a single component, which can be purchased in a unified manner and is more convenient for production and manufacturing.
[0058] A second step 530 matching the sealing ring 130 is provided below the first step 520. The sealing ring 130 is clamped between the second step 530 and the annular groove 122. The ignition needle assembly 100 and the base 500 have a certain amount of compression when installed, which can completely seal the gap between the ignition needle assembly 100 and the base 500, preventing overflow from flowing from the gap to the tail of the ignition needle assembly 100, thereby solving the problem of discharge at the tail of the ignition needle assembly 100 and improving the ignition performance.
[0059] The flexible protective cover 300 is multi-layered, thereby better protecting the rear end of the ignition needle assembly 100 and preventing overflow from flowing into the rear end of the ignition needle assembly 100. In this embodiment, the flexible protective cover 300 is two-layered. In other embodiments, the number of layers of the flexible protective cover 300 may be selected as appropriate by those skilled in the art.
[0060] The hard protective cover 200 extends in the vertical direction, so as to better guide the wire 140 and prevent the wire 140 or the protective cover from hitting the high-temperature wall of the base 500, thereby avoiding damage to the wire 140 or the protective cover.
[0061] The flexible protective sleeve 300 partially extends into the ignition needle assembly 100 , thereby better protecting the connection between the wire 140 and the needle body 110 , preventing overflow from flowing into the connection between the wire 140 and the needle body 110 , and improving the ignition performance.
