Heating device on hot air desoldering station

Abstract

The utility model discloses a heating device on a hot air desoldering station, which comprises a pipe body, an air guide piece, a heating piece and a temperature detection piece, the pipe body is provided with an air inlet and an air outlet, the air guide piece is arranged in the pipe body, and a first cavity communicated with the air outlet and a second cavity communicated with the air inlet are formed in the pipe body; the heating part is arranged in the second cavity, the temperature detection part is arranged in the first cavity, the air guide part comprises a plurality of spiral walls, the spiral walls are rotationally and symmetrically arranged around the axis of the air guide part to form a plurality of air guide openings communicating with the first cavity and the second cavity, and hot air in the second cavity spirally flows into the first cavity from the air guide openings so as to mix air in the first cavity. According to the utility model, the temperature in the first chamber is uniform, and the temperature detected by the temperature detection piece is more accurate, so that the problem of deviation between the temperature of hot air exhausted from the air outlet and the preset temperature of the host is solved, the working efficiency is greatly improved, and the problem that components are damaged by high temperature is avoided.
