Environment-friendly energy-saving hot air soldering station with automatic switch

Abstract

The invention discloses an environment-friendly energy-saving hot air soldering station with an automatic switch, which relates to a hot air soldering station, and is mainly developed to solve the problem that the conventional hot air soldering station has no automatic switch. The automatic switch adopts a form of the interaction of a dry reed pipe and a permanent magnet plus a relay. When the dry reed pipe approaches the permanent magnet of a handle bracket in a handle, a reed of the dry reed pipe is magnetized to make a contact closed, so that a coil of the relay is electrified to actuate, a normally closed contact is disconnected to cut off a thyristor trigger signal, a heating element is switched off to stop heating, a normally open contact of the relay is closed to control an air pump motor for time-delay work at the same time, and the shutdown is performed after the maximum airflow is given to the heating element for heat dissipation; and when the handle leaves the handle bracket, the handle begins to work so as to have the function of the automatic switch. The hot air soldering station has the advantages that: the hot air soldering station can prolong more than one time using period of the heating element, save more than 30 percent of electricity, and also prolong more than one time operation period of hot air soldering stations at the same time.

Description

Technical field: [0001] The invention relates to a hot air soldering station used in electronic product research, teaching and production units. Background technique: [0002] Existing domestic hot air soldering stations sold as commodities only use an ordinary power switch to control opening and closing, but there is no automatic switch. Due to the particularity of the use of the hot air soldering station, it is frequently in the "on" and "off" states, so it is extremely inconvenient to rely on a switch to control, and often forget to turn off the power, resulting in wasteful energy consumption of the high-power heating core, and high temperature work, resulting in The life of the heating core is short, and the PCB components are damaged, which eventually leads to the shutdown of the hot air soldering station. Invention content: [0003] The purpose of the present invention is to provide an environment-friendly and energy-saving automatic switch hot-air soldering station...
