Example Embodiment

[0012] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0013] Such as figure 1 , figure 2 As shown, the present invention is a ceramic protective sleeve, which includes a ceramic sleeve 1 and two plugs 2. The plugs 2 are of a circular truncated cone structure made of rubber, and the inner end of the plugs 2 is provided with a bore 3, The bore 3 is embedded with a ceramic cylinder 4, and the end surface of the ceramic cylinder 4 at the entrance of the bore 3 is flush with the inner end surface of the plug 2. The outer wall of the plug 2 is provided with striped protrusions 5, so The two ends of the inner wall of the ceramic sleeve 1 are provided with slope openings 6, and the slope opening 6 is matched with the plug 2, and...

Abstract

The invention discloses a ceramic protective sleeve. The ceramic protective sleeve comprises a ceramic sleeve cylinder and two plugs. The plugs are of round table structures made of rubber, a boring hole is formed in the inner end face of each plug, and ceramic cylinder bodies are embedded in the boring holes; the end faces, located at entrances of the boring holes, of the ceramic cylinder bodies are flush with the inner end faces of the plugs; stripe-like protrusions are arranged on the outer wall of the plugs, slope openings are formed in the two ends of the inner wall of the ceramic sleeve cylinder and are matched with the plugs, and the slope openings and the ceramic sleeve cylinder are of integral structures. According to the ceramic protective sleeve, a sticking mode is not required to be used, an ignition electrode is plugged into the ceramic protective sleeve, the two ends are plugged with the plugs, so that the ignition electrode is blocked and fixed by the inner end surfaces of the plugs, the periphery of the ignition electrode makes contact with an insulated and high-temperature resistant ceramic, so that rapid and reliable installation is realized, and protective function of the ceramic protective sleeve is not affected.

Description

technical field [0001] The invention relates to a ceramic protective sleeve, which is used for the protection of the ignition electrode on the ignition needle. Background technique [0002] Water heaters and gas stoves are often ignited by ignition pins. The ignition pins generally emit electric sparks through the ignition electrodes, and the ignition electrodes need insulation, high temperature resistance and explosion-proof protective covers. At present, the best is the ceramic protective cover. , Since the surface of the ceramic protective sleeve is smooth and integrally formed, it is often connected to the ignition electrode by sticking, but this connection is not reliable and relies too much on the experience of the operator, which makes it difficult to guarantee the quality of the ignition needle in batches. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings, the present invention provides a ceramic protective sleeve with a novel...
