The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. In order to highlight the focus of the present invention, some conventional devices, apparatuses, components and operations are omitted or only briefly described herein.

Referring to fig. 1 and 2, the dustproof nixie tube comprises a nixie tube body 100, an upper dustproof frame 201, a lower dustproof frame 202 and four dustproof strips 203. The upper dustproof frame 201 is sleeved on the upper edge of the nixie tube body 100, and the lower dustproof frame 202 is sleeved on the lower edge of the nixie tube body 100; four dust excluders 203 set up respectively in charactron body 100 four corners edge to prevent that the dust from getting into inside charactron body 100, also can take precautions against earthquakes, play the effect of protection charactron, the top and the last dustproof frame 201 fixed connection of dust excluder 203, the bottom and the lower dustproof frame 202 fixed connection of dust excluder 203. The upper dust-proof frame 201 is made of hard materials such as plastics, and the lower dust-proof frame 202 and the dust-proof strip 203 are made of flexible materials such as silica gel, so that the installation is convenient.

Referring to fig. 1 and 2, in order to remove dust on the display panel of the nixie tube, the dustproof nixie tube further comprises a dust removal device. The dust removing device comprises a dust removing piece and a bracket. The dust removing part comprises a rotating shaft 301, a brush body 302 and a handle 303. The handle 303 is U-shaped. The handle 303 and the rotating shaft 301 are jointly arranged to form a fixed frame. In a preferred embodiment, the brush body 302 is rotatably mounted on the rotating shaft 301, and two ends of the handle 303 are fixedly connected to two ends of the rotating shaft 301 respectively. In another preferred embodiment, the brush body 302 is fixedly installed on the rotating shaft 301, and two ends of the handle 303 are respectively rotatably connected with two ends of the rotating shaft 301.

Referring to fig. 1 and 2, the bracket includes a first vertical plate 401, a second vertical plate 402, a cross bar 403 disposed at two ends of the first vertical plate 401, a stopper 405 movably connected to the cross bar 403, and a torsion spring 404 for connecting the cross bar 403 and the stopper 405. First riser 401 is fixedly mounted on the first side of upper dustproof frame 201, second riser 402 is fixedly mounted on the second side of upper dustproof frame 201, and first riser 401 and second riser 402 both extend upward.
