Description

Technical Field

[0001] The utility model relates to the technical field of water-saving devices, and particularly relates to a water-saving device capable of filtering impurities. Background Art

[0002] A water-saving device is a water-saving device that achieves the purpose of water conservation through technological innovation on the basis of an existing ordinary faucet. One way of water conservation is to divert water flow to control water consumption, and the other is to control water consumption through an inductive device to achieve water conservation. The water-saving device has the same functions as an ordinary faucet and must have the functions of saving water and maintaining water flow.

[0003] When the existing water-saving device works, the infrared sensor remains in an activated state, and the power consumption is relatively serious when no one is using water. When disassembling and assembling the existing water-saving device, the main water valve needs to be closed, which greatly affects the water use of other water levels. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that when the existing water-saving device works, the infrared sensor remains in an activated state, and the power consumption is relatively serious when no one is using water. When disassembling and assembling the existing water-saving device, the main water valve needs to be closed, which greatly affects the water use of other water levels.

[0005] To solve the above technical problem, the technical solution of the utility model is a water-saving device capable of filtering impurities, including a faucet, an electric control valve and a filter. The electric control valve is installed on the lower end surface of the faucet, the filter is installed on the inner wall surface of the electric control valve, two contact switches are connected to the outer wall surface of the faucet, a reset structure is connected to the upper wall surfaces of the two contact switches, a water-saving structure is sleeved on the outer wall surface of the electric control valve, and a wire hole is opened on the faucet, and a trigger structure is installed in the wire hole.

[0006] As a further scheme of the utility model: the reset structure includes: two connecting plates, two guide rods, two guide sleeves and two limiting plates; the two connecting plates are respectively connected to the upper wall surfaces of the two contact switches, the two guide rods are respectively installed on the outer wall surfaces of the two connecting plates, the two guide sleeves are respectively sleeved on the outer wall surfaces of the two guide rods, and the two limiting plates are respectively installed on the outer wall surfaces of the two guide sleeves and are fixed to the faucet.

[0007] As a further scheme of the utility model: the water-saving structure includes: a water-saving device, a pressing block and a plurality of infrared sensors; the water-saving device is sleeved on the outer wall surface of the electric control valve and is connected to the faucet by external threads, the pressing block is installed on the upper wall surface of the water-saving device, when the water-saving device is installed on the faucet, the pressing block triggers the two contact switches, and the plurality of infrared sensors are respectively installed on the lower wall surface of the water-saving device.

[0008] As a further solution of the present utility model: the triggering structure includes: a triggering wire, a power supply battery, a sensing wire, and a pressure sensor; one end of the triggering wire is connected to two contact switches through a wire hole, the power supply battery is installed at the other end of the triggering wire, one end of the sensing wire is connected to the power supply battery, and the pressure sensor is connected to the other end of the sensing wire.

[0009] As a further solution of the present utility model: the electric control valve is connected to the faucet by internal threads.

[0010] As a further solution of the present utility model: return springs are respectively sleeved on the outer wall surfaces of the two guide rods.

[0011] As a further solution of the present utility model: the inclination angle of the pressing block is the same as the angle of the contact switch.

[0012] The present utility model adopts the above technical solutions and has the following advantages compared with the prior art:

[0013] Before the water flows out, it is filtered through a filter. When the water-saving device is installed on the faucet, the two contact switches move into the faucet and are triggered. The two guide rods are driven by two connecting plates to move outwards along the two guide sleeves respectively, and the two return springs are stretched. At this time, the electric control valve is opened. As the water-saving device is unscrewed from the faucet, the pressing block disengages from the two contact switches, and the two return springs drive the two connecting plates to reset. The two connecting plates drive the two guide rods to reset along the two guide sleeves, and the two connecting plates drive the two contact switches to reset. The two contact switches control the electric control valve to close. At this time, water cannot flow out of the electric control valve, solving the problem that when disassembling and assembling the existing water-saving device that can filter impurities, the main water valve needs to be closed, which greatly affects the water use of other water levels.

[0014] During use, the operator stands on the pressure sensor. When the pressure sensor detects that the gravity exceeds the set value, several infrared sensor switches are triggered. When the operator's hand extends below several infrared sensors, several infrared sensors are triggered to control the water-saving device to discharge water. When the operator retracts the hand, several infrared sensors do not detect a signal, and the water-saving device is controlled to close, solving the problem that when the existing water-saving device that can filter impurities works, the infrared sensors remain in an activated state, and there is a serious waste of electricity when no one is using water.

[0023] Please refer to Figure 3 , the reset structure includes: two connecting plates 6, two guide rods 7, two guide sleeves 8 and two limit plates 9; the two connecting plates 6 are respectively connected to the upper wall surfaces of the two contact switches 4, the two guide rods 7 are respectively installed on the outer wall surfaces of the two connecting plates 6, the two guide sleeves 8 are respectively sleeved on the outer wall surfaces of the two guide rods 7, and the two limit plates 9 are respectively installed on the outer wall surfaces of the two guide sleeves 8 and are fixed to the faucet 1.

[0024] Please refer to Figure 2 , the electric control valve 2 and the faucet 1 are connected by internal threads. In this embodiment, the electric control valve 2 and the faucet 1 can be quickly disassembled and assembled through threaded connection.

[0025] Please refer to Figure 3, a return spring 17 is sleeved on the outer wall surfaces of the two guide rods 7 respectively. In this embodiment, as the water saver 10 is unscrewed from the faucet 1, the pressing block 11 disengages from the two contact switches 4, and the two return springs 17 drive the two connecting plates 6 to reset.

[0026] Please refer to Figure 4 , characterized in that the inclination angle of the pressing block 11 is the same as the angle of the contact switch 4. In this embodiment, the same angle can make it more convenient for the pressing block 11 to drive the contact switch 4 to move.

[0027] In this embodiment, the water flow is filtered by the filter 3 before the water flows out. When the water saver 10 is installed on the faucet 1, the two contact switches 4 move into the faucet 1 and are triggered. The two connecting plates 6 drive the two guide rods 7 to move outwards along the two guide sleeves 8 respectively, and the two return springs 17 are stretched. At this time, the electric control valve 2 is opened. As the water saver 10 is unscrewed from the faucet 1, the pressing block 11 disengages from the two contact switches 4, and the two return springs 17 drive the two connecting plates 6 to reset. The two connecting plates 6 drive the two guide rods 7 to reset along the two guide sleeves 8, and the two connecting plates 6 drive the two contact switches 4 to reset. The two contact switches 4 control the electric control valve 2 to close, and at this time, water cannot flow out of the electric control valve 2.

[0028] Specifically, when the water saver 10 is installed on the faucet 1, the two contact switches 4 move into the faucet 1 and are triggered. The two connecting plates 6 drive the two guide rods 7 to move outwards along the two guide sleeves 8 respectively, and the two return springs 17 are stretched. At this time, the electric control valve 2 is opened. When the water saver 10 needs to be replaced, as the water saver 10 is unscrewed from the faucet 1, the pressing block 11 disengages from the two contact switches 4, and the two return springs 17 drive the two connecting plates 6 to reset. The two connecting plates 6 drive the two guide rods 7 to reset along the two guide sleeves 8, and the two connecting plates 6 drive the two contact switches 4 to reset. The two contact switches 4 control the electric control valve 2 to close, and at this time, water cannot flow out of the electric control valve 2 until the operator reinstalls the water saver 10 and uses the water saver 10 to drive the pressing block 11 to trigger the two contact switches 4 again.

[0029] Embodiment 2, please refer to Figure 4 , the water-saving structure includes: a water saver 10, a pressing block 11 and several infrared sensors 12; the water saver 10 is sleeved on the outer wall surface of the electric control valve 2 and is connected to the faucet 1 by an external thread. The pressing block 11 is installed on the upper wall surface of the water saver 10. When the water saver 10 is installed on the faucet 1, the pressing block 11 triggers the two contact switches 4, and several infrared sensors 12 are respectively installed on the lower wall surface of the water saver 10.

[0030] Please refer to Figure 5, the triggering structure includes: a triggering wire 13, a power supply battery 14, a sensing wire 15, and a pressure sensor 16; one end of the triggering wire 13 is connected to two contact switches 4 through a wire hole 5, the power supply battery 14 is installed at the other end of the triggering wire 13, one end of the sensing wire 15 is connected to the power supply battery 14, and the pressure sensor 16 is connected to the other end of the sensing wire 15.

[0031] In this embodiment, during use, the operator stands on the pressure sensor 16. When the pressure sensor 16 detects that the gravity exceeds the set value, it triggers the switches of several infrared sensors 12. When the operator extends their hand below the several infrared sensors 12, the several infrared sensors 12 are triggered, controlling the water-saving device 10 to discharge water. When the operator retracts their hand, the several infrared sensors 12 do not detect a signal, controlling the water-saving device 10 to close.

[0032] Specifically, during use, the operator stands on the pressure sensor 16. When the pressure sensor 16 detects that the gravity exceeds the set value, it triggers the switches of several infrared sensors 12. When the operator extends their hand below the several infrared sensors 12, the several infrared sensors 12 are triggered, controlling the water-saving device 10 to discharge water. When the operator retracts their hand, the several infrared sensors 12 do not detect a signal, controlling the water-saving device 10 to close. When the operator leaves the pressure sensor 16 and extends their hand below the several infrared sensors 12, since the pressure sensor 16 does not trigger the switches of the several infrared sensors 12, the water-saving device 10 is not opened and no water flows out.
