Problems solved by technology

[0003] When in use, the autoclave usually needs to be kept for a period of time after reaching the specified temperature and pressure before powering off. The traditional method is to use manual timing, and manually pull down the switch after reaching the specified time, which is troublesome and expensive. There is a problem of untimely power failure caused by operation errors, which causes a great waste of electric energy

Abstract

The invention discloses a delayed power-off device. The delayed power-off device comprises a box (1), and an alternating current contactor (2) is arranged in the box (1). The delayed power-off device further comprises a delay relay (3), and the delay relay (3) is connected with the alternating current contactor (2) in series and is a time-adjustable delay relay. An off switch (4), an on switch (5) and a delay switch (6) are arranged on the box (1), the off switch (4) and the on switch (5) are connected with the alternating current contactor (2), and the delay switch (6) is connected with the delay relay (3). A locking device is further arranged in the box (1), and a key hole (7) is formed in the outer side of the box (1). According to the delayed power-off device, as the delay relay is arranged, automatic timing outage is achieved after the specified temperature and the specified pressure are reached, the accuracy of timekeeping is improved, labor is saved, waste of electric energy is avoided, and safety is high in the using process.

Description

technical field [0001] The invention belongs to the field of electrical technology, in particular to a switch device, in particular to a time-delayed power-off device. Background technique [0002] Autoclave, also known as high-pressure steam sterilizer, is a device that uses electric heating wire to heat water to generate steam and maintain a certain pressure. It mainly consists of a sealable cylinder, pressure gauge, exhaust valve, safety valve, electric heating Composed of silk, etc., it is suitable for medical and health services, scientific research, agriculture and other units to sterilize medical equipment, dressings, glassware, solution culture media, etc. [0003] When in use, the autoclave usually needs to be kept for a period of time after reaching the specified temperature and pressure before powering off. The traditional method is to use manual timing, and manually pull down the switch after reaching the specified time, which is troublesome and expensive. There...
