Description

Technical Field

[0001] This utility model relates to the field of ceramic ignition needle technology, specifically a ceramic ignition needle with a protective sheath. Background Technology

[0002] Currently, existing gas stove burners require an ignition needle for ignition. Since these needles are typically made of brittle ceramic and are usually exposed without proper protection, they are easily damaged or broken during transportation, installation, debugging, cleaning, and maintenance due to collisions with other components. This can lead to excessive ignition gaps, electrical leakage, and difficulty in igniting the burner. Furthermore, existing ignition needles are often difficult to disassemble and reassemble, and they wear down over time. Excessive wear can cause the needle to fail, resulting in numerous inconveniences during use. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a ceramic ignition needle with a sheath, which has the following beneficial effects:

[0014] This invention has the advantage of easy disassembly and assembly of the ignition needle. The operator turns on the servo motor on the housing, which drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the two moving plates to move closer to each other.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] See Figure 1-4 A ceramic ignition needle with a protective sleeve includes a main body assembly 1; the main body assembly 1 includes an ignition needle body 11, on which a protective sleeve 12 is disposed; a disassembly assembly 2 is disposed on the ignition needle body 11, the disassembly assembly 2 including: a mounting base 27 disposed on the protective sleeve 12; a housing 21 fixedly connected to the top of the mounting base 27; a bidirectional threaded rod 22 rotatably connected to the inner side wall of the housing 21; a servo motor 23 fixedly connected to the outer side wall of the housing 21, and its output end fixedly connected to the bidirectional threaded rod 22; and a moving plate 24 threadedly connected to the bidirectional threaded rod 22. The outer wall of the threaded rod 22 is slidably connected to the inner wall of the housing 21, and two are symmetrically arranged; clamping plates 25 are provided on the opposite sides of the two moving plates 24; shock-absorbing springs 26 are provided on each clamping plate 25, and the two ends of each shock-absorbing spring 26 are respectively fixedly connected to the outer wall of the clamping plate 25 and the outer wall of the moving plate 24 on the same side; anti-slip pads 5 are fixedly connected to the opposite sides of the two clamping plates 25; a pressure sensor 6 is provided on the outer wall of one side of the anti-slip pad 5, and the pressure sensor 6 is electrically connected to the servo motor 23.

[0027] When ready for use, the ignition needle body 11 is protected by the protective sleeve 12. During installation, the operator picks up the protective sleeve 12 while simultaneously placing the ignition needle body 11 on the mounting base 27. The operator then turns on the servo motor 23 on the housing 21, causing the servo motor 23 to rotate the bidirectional threaded rod 22. The rotation of the bidirectional threaded rod 22 causes two moving plates 24 to move closer together. The two moving plates 24, through their shock-absorbing springs 26, cause two clamping plates 25 to move closer together, clamping and fixing the protective sleeve 12. For disassembly, simply reverse the rotation of the output end of the servo motor 23. When the protective sleeve 12 receives an impact, the shock-absorbing springs 26 on both sides extend and retract, generating heat. Vibration reduction is applied to the device, thereby improving its practicality. When the two clamping plates 25 move, they drive the anti-slip pads 5 on them to move simultaneously, so that the anti-slip pads 5 directly contact the protective sleeve 12, increasing the friction between the device and the protective sleeve 12, and thus improving the device's fixing effect. When the anti-slip pads 5 contact the protective sleeve 12, one side of the anti-slip pads 5 drives the pressure sensor 6 on it to be squeezed simultaneously with the protective sleeve 12. When the pressure reaches the set value on the pressure sensor 6, the pressure sensor 6 transmits an electrical signal to the controller, and the controller transmits an electrical signal to the servo motor 23. Subsequently, the servo motor 23 automatically shuts down, without the need for manual shutdown by the operator, and can prevent the device from being over-clamped, improving the device's convenience.

[0028] Example 2

[0029] See Figure 1-4 Based on Embodiment 1, a positioning function has been added;

[0030] The ignition needle body 11 is provided with a positioning component 3, which includes: mounting blocks 31, which are fixedly connected to the top of the mounting base 27 and are arranged symmetrically; springs 33, which are fixedly connected to the opposite surfaces of the two mounting blocks 31; positioning rings 32, which are fixedly connected to one end of the two mounting blocks 31 and are slidably connected to the top of the mounting base 27; guide rail covers 4 are provided on the two moving plates 24; and dampers 7 are provided on the two moving plates 24.

[0031] During installation, the operator places the protective sleeve 12 inside the positioning ring 32. At this time, the protective sleeve 12 is positioned at the center of the two side clamping plates 25, thus preventing the protective sleeve 12 from being misplaced and tilting when it is fixed under force. When the protective sleeve 12 is impacted, it causes the springs 33 on the two side mounting blocks 31 to extend and retract simultaneously, without affecting the normal shock absorption of the device, thus improving the convenience of the device. When the moving plate 24 moves, it causes the guide rail cover 4 to fold or unfold simultaneously. The guide rail cover 4 can cover the slide groove required for the movement of the moving plate 24 on the housing 21, preventing dust and other debris from entering the slide groove and causing blockage, which would affect the normal movement of the moving plate 24, thus improving the stability of the device. When the clamping plate 25 moves, it causes the damper 7 on the moving plate 24 on the same side to move simultaneously. The damper 7 moves back and forth with the vibration structure through the damping rod, causing the piston to move in the cylinder filled with hydraulic oil. The small holes or gaps on the piston force the hydraulic oil to pass through, generating viscous resistance and internal friction between fluid molecules, converting the vibration kinetic energy into heat energy for dissipation, thereby increasing its fixed stability and preventing shaking.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
