Abstract
The utility model discloses an emergency exhaust fan, which comprises an exhaust fan, a storage battery and a power-off changeover switch, wherein a mains supply is connected with the exhaust fan through a plug and a socket; the mains supply is also connected with the power-off changeover switch; and the storage battery is connected with the exhaust fan through the power-off changeover switch. The emergency exhaust fan provided by the utility model has the beneficial effect that after a fire breaks out, under the condition that the mains supply is cut off, the fan can be automatically switched on, and dense smoke is discharged in time, and thus better conditions are provided for escape or rescue.
Description
Technical field
The utility model relates to a kind of ventilating fan, more particularly, relates to a kind of emergent ventilating fan.
Background technique
At present, indoor public place all is provided with the fire circuit breaking protective system mostly, in case breaking out of fire; general power meeting automatic disconnection prevents that the condition of a disaster of fire from enlarging, although opened window; but smog is too much, is difficult to instant discharge, and fire disaster escaping or the people that rescues are caused very large impact.
The model utility content
The purpose of this utility model be to provide a kind of can be after breaking out of fire, the emergent ventilating fan of automatically opening in the situation of civil power outage.
A kind of emergent ventilating fan of the present utility model comprises ventilating fan, storage battery and outage diverter switch, and civil power is connected with ventilating fan by plug and socket, and wherein, civil power also is connected with the outage diverter switch, and storage battery is connected with ventilating fan by the outage diverter switch.
Above-mentioned a kind of emergent ventilating fan, described storage battery are high power lithium battery.
The utility model adopts battery-driven mode, in the situation that power supply disconnects, by the circuit between outage diverter switch connection storage battery and the ventilating fan, realize the technique effect that ventilating fan is opened automatically, the utility model is used as emergent, to fire disaster escaping or the condition that provides is provided.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 is ventilating fan, and 2 is storage battery, and 3 are the outage diverter switch, and A is civil power.
Embodiment
As shown in Figure 1, a kind of emergent ventilating fan comprises ventilating fan 1, storage battery 2 and outage diverter switch 3, and civil power is connected with ventilating fan 1 by plug and socket 4, and civil power also is connected with outage diverter switch 3, and storage battery 2 is connected with ventilating fan 1 by outage diverter switch 3; Storage battery 2 is high power lithium battery.
The utility model is when concrete the use, when breaking out of fire within doors, by fire circuit breaking protective system automatic disconnection civil power A; trigger simultaneously outage diverter switch 3; connect circuit between storage battery 2 and the ventilating fan 1, ventilating fan 1 is opened automatically, makes dense smoke timely from discharging within doors.
