Embodiment 1
[0041] Such as Figure 1-3 As shown, a lighting device with gas purification function for underground engineering includes a lamp body 1 with a protective cover 2 for collecting gas outside the lamp body 1 and an annular purification box 3 outside the lamp body 1 .
[0042] The protective cover 2 includes: a plurality of vertical pipes 21, the upper ends of the vertical pipes 21 communicate with the purification box 3, and the lower ends of the plurality of vertical pipes 21 are jointly connected with a fixing seat 22; a plurality of horizontal pipes 23, the horizontal pipes 23 are fixedly connected to each phase Between adjacent vertical tubes 21, multiple vertical tubes 21 and multiple horizontal tubes 23 are braided together to form protection, which can prevent the lamp body 1 from being overheated and cause burns to the user, and can also avoid sharp objects from damaging the lamp body 1 during construction , the horizontal tube 23 is provided with a plurality of air inta...
Embodiment 2
[0053] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the horizontal pipe 23 is arranged obliquely, the fixing base 22 communicates with the lower ends of a plurality of vertical pipes 21 , and the lower end of the fixing base 22 is threadedly connected with an ash storage bucket 221 .
[0054] In this embodiment, since the horizontal pipe 23 is arranged obliquely, the large particles of impurities can be rolled down under the action of their own gravity, and collected to the lowermost ash storage bucket 221 through the vertical pipe 21, which is convenient for the operator to process. At the same time, it is possible to reduce large particles of impurities staying at the small air intake holes 231 and reduce the occurrence of clogging.
