[0002] Currently, ignition needles are widely used in industrial and household equipment, such as gas stoves and boilers.

[0003] However, the ignition needles in the prior art have the following significant drawbacks during installation and use:

[0004] 1. Complex installation: Traditional ignition needles are usually fixed to the metal panel or burner base with screws. During installation, tools such as screwdrivers are needed to tighten or loosen them. The operation steps are cumbersome, which is not only time-consuming and labor-intensive, but also increases the difficulty of maintenance.

[0005] 2. Poor waterproof performance: The existing ignition needle's connector lacks effective waterproof measures, and water can easily seep into the connector, causing short circuits or corrosion, affecting the normal operation of the ignition needle, and even causing safety hazards.

[0006] 3. Inconvenient maintenance: Due to the complex installation method, the ignition needle is difficult to disassemble when it needs to be replaced or repaired, which increases maintenance costs and time.

[0007] Therefore, we propose a plug-in waterproof ignition needle. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] This embodiment is a plug-in waterproof ignition needle.

[0028] like Figure 1-4 As shown, the device includes a fixing plate 1. A first through hole 2 is provided on the upper outer surface of the fixing plate 1. A plug-in ignition needle 3 passes through the first through hole 2. A second through hole 4 is provided on the upper end of the fixing plate 1. There are two sets of second through holes 4, which are located on both sides of the first through hole 2. A connector 8 is fixedly installed on the lower outer surface of the plug-in ignition needle 3. A waterproof cover 7 is fixedly installed on the lower outer wall of the plug-in ignition needle 3, and the waterproof cover 7 covers the outside of the connector 8. A plug-in shaft 5 is fixedly installed on the left and right sides of the upper outer surface of the waterproof cover 7. A snap-fit ​​assembly 6 is installed on the upper part of one side of the outer surface of the plug-in shaft 5. The snap-fit ​​assembly 6 includes a mounting groove 10, a limiting block 11, a guide hole 12, a guide rod 13, and a spring 14. A compression spring 9 is sleeved on the lower part of the plug-in shaft 5. The lower outer surface of the compression spring 9 is fixedly connected to the upper outer surface of the waterproof cover 7.

[0029] The outer wall of the insertion shaft 5 is inserted into the second through hole 4, and the upper end of the insertion shaft 5 extends through to the upper part of the fixing plate 1. The snap-fit ​​assembly 6 is located on the upper part of the fixing plate 1. The mounting groove 10 is opened on the upper part of the outer surface of one side of the insertion shaft 5. The guide rod 13 and the spring 14 are both located in the mounting groove 10. The guide hole 12 is opened on the outer surface of one end of the limiting block 11. The outer surface of one end of the guide rod 13 is fixedly connected to one end of the mounting groove 10. The spring 14 is movably sleeved on the outer wall of the guide rod 13. The spring 14 is fixedly mounted on the outer wall of the guide rod 13. The mounting slot 10 is installed between one end of the mounting groove 10 and the outer surface of one end of the limiting block 11. The outer wall of the limiting block 11 is slidably connected to the mounting groove 10. The limiting block 11 is slidably connected to the outer wall of the guide rod 13 through the guide hole 12.
