Air detection device with telescopic and storable probe

Abstract

The invention discloses an air detection device with a telescopic and storable probe. The device comprises a mounting base, a probe and a telescopic base, a telescopic groove is formed in the middle in the mounting base, and the telescopic base is located at the upper end in the telescopic groove. The telescopic seat is slidably connected with the telescopic groove; the probe is of a cylindrical structure, the probe is transversely placed in the upper end surface of the telescopic seat, and two ends of the probe are rotationally connected with the telescopic seat through small shafts. The beneficial effects are that: a telescopic motor works to drive a threaded rod to rotate, the threaded rod is in threaded connection with a threaded sleeve, the telescopic base can move in the direction ofthe telescopic groove, the probe can be accommodated in the telescopic groove, a sliding door is arranged, the sliding door is automatically closed under the action of a spring, dust in the air is prevented from entering the telescopic groove, the probe is subjected to dustproof protection, the probe can be driven to rotate through work of a rotating motor, a wiping cotton layer can wipe a detection area of the probe when the probe rotates, dust adhering to the surface of the probe is removed, and the detection sensitivity of the probe is guaranteed.

Description

technical field [0001] The invention relates to an air detection device with retractable and accommodating probes, belonging to the technical field of air detection equipment. Background technique [0002] At present, most of the air detection devices on the market are composed of detection instruments and probes. The probes are placed inside the detection container through the mounting base to collect data. However, the current probes are all installed in a fixed structure, and the surface of the probe adheres to the surface during long-term placement. There is a lot of dust, which affects its detection sensitivity and needs to be improved. Contents of the invention [0003] The object of the present invention is to provide an air detection device with retractable probes to solve the problem that the current probes proposed in the above background technology are all installed in a fixed structure, and a large amount of dust adheres to the surface of the probe during the l...
