The utility model adopts an electric power circuit, a gas detection circuit, a switch circuit, a sound simulating circuit, a transfer circuit, etc., to realize the multifunctional safety alarm with theft protection, automatic removing of the dangerous gas, automatic alarm, door bell, etc. The utility model has the advantages of compact structure, power consumption saving, safety, fast reaction, simple installation and easy use.
Description
The utility model belongs to the electronic auto-control device, and is particularly antitheft, inflammable gas is got rid of automatically, multi-functional safety alarms such as warning, doorbell automatically.
At present, commercially available alarm, doorbell generally all are single, and as the Chinese patent 88208936.6 disclosed toxic gases ejector of reporting to the police automatically, it is just reported to the police automatically, gets rid of after toxic gas surpasses finite concentration.And using relay in circuit, easily produce spark, is unfavorable for inflammable gas.Chinese patent 86201130 discloses a kind of scavenger fan self-actuated controller that guards against gas poisoning in addition, also is to use relay in electronic circuit, easily produces spark.It is convenient inadequately that they equally are that one or two functions use.
The novel purpose of this practicality is exactly will overcome above-mentioned not to be, and a kind of multifunctional household protector that provides.
The solution that realizes the utility model purpose is to comprise power circuit, Detection Circuit, on-off circuit, simulated sound circuit, it is characterized in that having control simulated sound circuit to send the change-over circuit of alternative sounds, on-off circuit adopts the bidirectional triode thyristor of not sparking simultaneously.
Realizing the solution of the utility model purpose, can be that on-off circuit and break alarm and doorbell are that the negative pole of acoustic simulation piece IC meets diode D
4Positive pole, diode D
4Negative pole meet diode D
5Positive pole, diode D
5Negative pole connect the selecting side of acoustic simulation piece IC, diode D simultaneously
