Using such scheme, the setting of instruction device, when the leakage control device is worked, can be referred to by instruction device Show, so as to give the prompting of people one, and in circuit malfunctions, maintenance personal can also used instruction device leak is controlled The quality of device makes preliminary judgement.

Preferably, the alarm device includes being coupled to leakage control device to receive leak control signal and export announcement The alarm control circuit of alert control signal, alarm control circuit is coupled to receive alarm control signal and export voice signal Sound circuit, be coupled to sound circuit with receive voice signal and in response to voice signal with realize the alarm of phonic warning electricity Road.

Using such scheme, the setting of control circuit, alarm control circuit control warning circuit conducting, when alarm is controlled are alerted After circuit processed receives the leak control signal of the high level of leakage control device output, sound circuit will be turned on, and language The setting of sound circuit, the alarm mode of warning circuit is not used traditional, dull sound, and use and set inside sound circuit The voice signal put is alerted, and improves sensitiveness of the installation personnel to warning circuit, and send language by warning circuit The sound of sound alarm, prompt effect good.

Preferably, the alarm device is also coupled to for disconnecting alarm device current supply circuit to realize the reset of reset Switch.

Using such scheme, the setting of reset switch, when the leakage inspector in housing detects water, alarm fills Put to be alerted always, now need to operate alarm device by reset switch, when needing that alarm device is entered When row resets, it is only necessary to press reset switch, it is possible to alarm device is resetted, it is easy to operate, it is practical.

Preferably, the alarm device also includes being coupled to alarm control circuit to receive alarm control signal and respond In alarm control signal and cut off the cut-out circuit of the current supply circuit of water purifier.

Using such scheme, the setting of circuit is cut off, when the leakage inspector one is detected leak in water purifier, except Carry out beyond alarm prompt, can also improve the protection of water purifier by cutting off the circuit of water purifier.

In summary, the utility model has the advantages that：

1st, when leak occurs for water purifier, will be alarmed；

2nd, the setting of sound circuit, the prompting effect to alarm is improved；

3rd, when leak occurs for water purifier, the current supply circuit of water purifier will be disconnected automatically.
