Abstract
The utility model discloses a water leakage protective device which is installed on home water appliances, and comprises a normally closed magnetic valve and a liquid level relay, wherein both the normally closed magnetic valve and the liquid level relay are supplied with power by a power supply; the normally closed magnetic valve is further connected with an output switch in series; the output switch is connected with a power supply control switch of the home water appliance; the liquid level relay is provided with two sensing terminals at the water leakage position; the signal output end of the liquid level relay is connected with the signal receiving end of the normally closed magnetic valve; and when the sensing terminals sense water leakage, the normally closed magnetic valve can be controlled to switch on the output switch so as to switch off the connection between the power supply and the home water appliance. Compared with the prior art, the water leakage protective device can cut off the connection between the power supply and the home water appliance in time when water leakage of the home water appliance occurs, and when the power supply is damaged and the electricity is cut off, the liquid level relay and the normally closed magnetic valve are simultaneously in the closed state to automatically cut off the water path.
Description
Technical field
The utility model relates to a kind of protective device that leaks, and belongs to the technical field of safe fluid device.
Background technology
Current social scientific and technological high speed development, the appliance water equipment and technology is fast development thereupon also, so water quality has also obtained good guarantee, but when obtaining good water quality, a large amount of water crises also occurred.Because problems such as the material of appliance water and appliance water ageing equipment cause appliance water equipment leakage accident to emerge in an endless stream, bring huge property loss for numerous families.The product of the general appliance water producer defencive function that all do not leak, thus cause the water crisis to can hardly be avoided, and the protective device function singleness of leaking of the prior art, reliability is low, can not satisfy people's requirement.
The utility model content
The purpose of the utility model be to provide a kind of can be when appliance water equipment leaks the protective device of timely power down process.
The utility model adopts following technical scheme to realize:
A kind of protective device that leaks; This device is installed on the appliance water equipment; Appliance water equipment is connected by power supply power supply and with a water inlet threeway and a water intake ball valve; It is characterized in that; The said protective device that leaks comprises a normally closed solenoid valve and a liquid level relay, and said normally closed solenoid valve is connected between into water threeway and the water intake ball valve, and said normally closed solenoid valve and said liquid level relay all are connected across both ends of power; Also be in series with an output switch between said power cathode and the normally closed solenoid valve; The power control switch of said appliance water equipment be connected on the negative pole of appliance water equipment and be connected on the negative pole of power supply after said output switch is connected, said liquid level relay is connected across both ends of power and has two induction terminals that place the place that leaks, the signal output part of said liquid level relay links to each other with the signal receiving end of said normally closed solenoid valve.
Further, said liquid level relay is a JYB transistor npn npn liquid level relay.
The useful technique effect that the utility model possesses is:
Liquid level relay has two induction terminals that are in the place that leaks; Can make when appliance water equipment leaks and form path between two induction terminals and to the liquid level relay input signal; Input signal is transferred to normally closed solenoid valve after the inner amplification of liquid level relay rectification; Normally closed solenoid valve is made action and is opened the output switch and cut off the electricity supply appliance water equipment is quit work, and reaches the purpose of protection appliance water equipment; The shared power supply of liquid level relay and appliance water equipment, liquid level relay is also opened normally closed solenoid valve and is started working synchronously when the appliance water equipment work; When power supply damaged outage, liquid level relay also was in closed condition simultaneously, and the water route cuts off automatically.
Description of drawings
Fig. 1 is the utility model structured flowchart that protective device protects appliance water equipment that leaks.
Fig. 2 is the leak circuit theory diagrams of protective device of the utility model.
Embodiment
Through facing the description of embodiment down; To help public understanding the utility model more; But can't be regarded as restriction by the concrete embodiment that the applicant is given to the utility model technical scheme, any definition to parts or technical characterictic change and/or to overall structure do form but not the conversion of essence all should be regarded as the protection range that technical scheme limited of the utility model.
The utility model preferred embodiment as depicted in figs. 1 and 2; Normally closed solenoid valve 11 is connected between into water threeway 13 and the water intake ball valve 14; Its output switch J1 one end links to each other with the power supply terminal negative pole of normally closed solenoid valve 11, and the other end connects the power control switch J9 of appliance water equipment 6, the preferred JYB transistor npn npn of liquid level relay liquid level relay; Induction terminal 7 in this circuit places the place that is prone to leak below the induction appliance water equipment with induction terminal 5, and promptly leakage point 15.When these two terminals are sensed water; Can form path between induction terminal 7 and the induction terminal 5 and send an input signal to liquid level relay 12; Then 12 pairs of these input signals of liquid level relay amplify, rectification and be transferred to normally closed electromagnetism through the signal that the terminal 1 and the terminal 8 of signal output part will be handled and close 11; The signal receiving end terminal 4 of normally closed solenoid valve 11 receives this signal; Make normally closed solenoid valve 11 that action take place and open output switch J1, cut off the path between appliance water equipment 6 and the power supply 10.The terminal 1 of liquid level relay 12 links to each other with the positive pole of power supply 10, and terminal 8 links to each other with the negative pole of power supply 10, and appliance water equipment 6 is also through power supply 10 power supplies, so liquid level relay 12 and appliance water equipment 6 common sources 10.The positive pole 4 of normally closed solenoid valve 11 links to each other with the terminal 1 of liquid level relay 12; The terminal 8 of liquid level relay 12 links to each other with the power supply negative pole of normally closed solenoid valve 11 through power control switch J9; So form an action synchronous circuit; After that is to say power supply 10 energisings, appliance water equipment 6 is just started working, and liquid level relay 12 also begins synchronous working and opens normally closed solenoid valve 11 automatically; Quit work otherwise work as household electrical appliances equipment 6, liquid level relay 12 is closed normally closed solenoid valve 11.And when power supply 10 damaged, liquid level relay 12 will quit work, and normally closed solenoid valve 11 just can be closed, and cuts off output switch J1 automatically the water route is cut off.
Certainly; The utility model can also have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
