Abstract
The invention discloses a protection circuit for a warmer, which belongs to the technical field of protection and alarm devices for electric equipment. The protection circuit for the warmer comprises a processor, a pressure sensor, a switch, a warning device, an automatic power-off circuit and a power supply, wherein the pressure sensor, the switch, the warning device, the automatic power-off circuit and the power supply are electrically connected with the processor respectively. The protection circuit has the benefits that when a person or an object touches a metal gauze, the warmer can make a warning sound timely and cut off the power automatically, thereby effectively avoiding an accident.
Description
Technical field
The present invention relates to a kind of warmer protective circuit, belong to electric type protection and warning device technical field.
Background technology
Warmer on the market only has and turns to and heat-regulatory function.Though the warmer outside is equipped with the metal guard, because child's finger is thinner, still can finger be inserted, simultaneously, if some inflammable object touchings are in the above, possible initiation fire exists potential safety hazard.Warmer does not in the market have and touches power-off protection and warning function.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of warmer protective circuit, effectively guarantees the safe in utilization of warmer.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of warmer protective circuit; Comprise processor, pressure sensor, switch, alarming device, automatic power-down circuit and power supply, pressure sensor, switch, alarming device, automatic power-down circuit and power supply are electrically connected with processor respectively; Described processor adopting single-chip microcomputer.
The invention has the beneficial effects as follows: when people or object touched the metal guard, warmer can in time send caution sound and outage automatically, effectively avoids the generation of accident.
Description of drawings
Fig. 1 is a theory diagram of the present invention
Embodiment
To combine accompanying drawing that the present invention is described further below.
As shown in Figure 1: the present invention includes processor, pressure sensor, switch, alarming device, automatic power-down circuit and power supply, pressure sensor, switch, alarming device, automatic power-down circuit and power supply are electrically connected with processor respectively; Described processor adopting single-chip microcomputer.
When nobody or object touching metal guard, the warmer operate as normal is when people or object touching metal guard; Pressure sensor is passed to processor with signal; The processor control switch cuts out, and warmer cuts off the power supply automatically and sounds the alarm, and effectively avoids the generation of accident.
Claims (2)
