The utility model solves the technical solution of the above technical problem: a kind of household water filter preventing water leakage protective device, packet Setting is included in household water filter bottom leakproof water tank, water stream channel is arranged in preventing water leakage water tank bottom, and top is with leakage hole Partition, further include the first conductive terminal, the second conductive terminal, liquid level sensor, inlet water solenoid valve, power supply, alarm device and control Device processed.

Further, the alarm device includes warning light or buzzer, and the controller is PLC controller.

Further, first conductive terminal, the second conductive terminal are fixed on partition and protrude into leakproof water tank, The alarm device and controller respectively with the first conductive terminal, the second conductive terminal is electrically connected and the first conductive terminal and second Mutually insulated between conductive terminal.

Further, further including insulating washer, two through hole is offered on partition, insulating washer is nested in the through-hole, First conductive terminal, the second conductive terminal are respectively nested in insulating washer.

Further, first conductive terminal, the second conductive terminal are metallic conduction post.

Further, the side of leakproof water tank is arranged in the liquid level sensor, highly lower than the first conductive terminal, the Two conductive terminal ends.

The household water filter preventing water leakage protective device of the utility model has the advantages that

(1) by setting liquid level sensor, for detecting leak liquid level in leakproof water tank, and the liquid level signal of detection It is transmitted to controller, when controller detects liquid level signal, then closes the inlet water solenoid valve of water purifier；

(2) by setting alarm device, the first conductive terminal, the second conductive terminal, increase by one layer of protection to household water filter, When liquid level sensor breaks down, in leakproof water tank water level rise to the first conductive terminal, at the second conductive terminal when, alarm Device, controller, the first conductive terminal and circuit conducting where the second conductive terminal, alarm device sound an alarm, and controller is closed net Water heater inlet solenoid valve is cut off the power simultaneously；

(3) the household water filter preventing water leakage protective device of the utility model is providing the same of double shield to household water filter When, also have device structure simple, the advantages that working service is simple, long service life.

Specific embodiment

Embodiment 1

As shown in Figure 1, the present embodiment provides a kind of household water filter preventing water leakage protective device, including be arranged in Domestic water purifying Water stream channel 9 is arranged in device bottom leakproof water tank 2, preventing water leakage water tank bottom, and top is the partition 10 with leakage hole, further includes First conductive terminal 31, the second conductive terminal 32, liquid level sensor 4, inlet water solenoid valve 6, power supply 7, alarm device 12 and controller 8.The alarm device 12 includes warning light or buzzer, and the controller 8 is PLC controller.

First conductive terminal 31, the second conductive terminal 32 are fixed on partition 10 and protrude into leakproof water tank 2, institute State alarm device 12 and controller 8 respectively with the first conductive terminal 31, the second conductive terminal 32 be electrically connected and the first conductive terminal 31 and second mutually insulated between conductive terminal 32.Specifically, further including insulating washer 11, two through hole is offered on partition 10, Insulating washer 11 is nested in the through-hole, and the first conductive terminal 31, the second conductive terminal 32 are respectively nested in insulating washer 11 It is interior.First conductive terminal 31, the second conductive terminal 32 are metallic conduction post.The liquid level sensor 4 is arranged in preventing water leakage The side of water tank 2 is highly lower than the first conductive terminal 31, the second conductive terminal end 32.Household water filter pipeline 1, water inlet pipe 5, inlet water solenoid valve 6 is arranged at the inside of household water filter.

The principles of the present invention are as follows: municipal tap water enters Domestic water purifying by inlet water solenoid valve 6 by water inlet pipe 5 Device pipeline 1, if there is the case where leak in water purifier pipeline, water flow is flowed into preventing water leakage water by the leakage hole on partition 10 Case 2, when the liquid level of leak rises at level sensor 4, the leak liquid level signal that liquid level sensor 4 will test is sent to Controller 8 then closes the inlet water solenoid valve 6 of water purifier and cuts off household water filter when controller 8 detects liquid level signal Power supply 7, household water filter stops working.And when level sensor 4 breaks down, the liquid level of leak will continue to go up, and work as water When arrival the first conductive terminal 31, the second 32 end of conductive terminal is flooded in position, since water is conductor, alarm device 12, first is conductive Terminal 31, the second conductive terminal 32 and the conducting of 8 place circuit of controller, controller 8 are closed the inlet water solenoid valve 6 of water purifier and are cut The power supply 7 of disconnected household water filter, while 12 signal an alert of alarm device, user, which sees, can further determine that household water filter is It is no to have stopped working.With this, double shield is carried out to household water filter.At the same time, preventing water leakage water tank bottom can be passed through Water stream channel 9 leak is discharged, check household water filter failure.
