Water purifier for controlling water production by faucet

Abstract

The utility model discloses a water purifier using a faucet to control water production, which comprises a filter system and a water outlet faucet, the filter system comprises a control unit and one or more filter elements, and the control unit controls the start and stop of the whole filter system, so that the water is purified through the filter elements; the last filter element in the filter system is directly connected with a water outlet faucet; a magnetic element is installed in a handle of the water outlet faucet, a Hall switch is arranged in a water outlet faucet body, and the Hall switch senses actions of the magnetic element in the handle and transmits signals to the control unit. When the water purifier works, the start and stop of the water purifier are directly controlled by the action of the switch handle, and the mode is more direct; meanwhile, the method does not depend on the pressure condition in a water path, so that a check valve behind a filter element can be omitted; and the Hall switch is in a non-contact type, so that the reliability is higher, and the service life is longer.

Description

Technical Field

[0001] The utility model belongs to the technical field of water purification equipment, in particular to a water purifier which controls water production by a tap. Background Art

[0002] As people pay more attention to the quality of drinking water, water purifiers are increasingly entering households. The basic principle of a water purifier is to filter tap water or other water sources through one or more filter elements to obtain purified drinking water. In this process, various valves and pumps are required to form waterways and circuits. Since the user's demand for purified water is discontinuous, that is, when the user does not need water, the water purifier does not work, and the water purifier starts to make water when the user needs it. Therefore, the water purifier should be started and stopped according to a certain command signal.

[0003] In the prior art, in order to send a start and stop signal to the water purifier, a pressure switch is installed between the filter outlet and the faucet to control the start and stop of the water purifier according to the pressure change; and in order to allow the pressure switch to accurately sense the pressure change, a check valve needs to be installed at the filter outlet to ensure that the end will not release pressure in the reverse direction. The disadvantage of this solution is that the check valve is not durable and will not play a check function after a long period of use, which will cause the pressure switch to misjudge and frequently start the water purifier to make water. Summary of the invention

[0004] The utility model aims to provide a water purifier which uses a tap to control water production, so as to make the start and stop control more reliable.

[0005] To this end, the technical solution adopted by the utility model is as follows: a water purifier that uses a faucet to control water production includes a filtering system and a water outlet faucet. The filtering system includes a control unit and one or more filter elements. The control unit controls the start and stop of the entire filtering system, thereby achieving water purification through the filter element; it is characterized in that: the last filter element in the filtering system is directly connected to the water outlet faucet; a magnetic element is installed in the handle of the water outlet faucet, and a Hall switch is built into the water outlet faucet body. The Hall switch senses the action of the magnetic element in the handle and transmits the signal to the control unit.

[0006] When the utility model is working, the start and stop of the water purifier are directly controlled by the action of the switch handle, which is more direct; at the same time, it does not depend on the pressure conditions in the water circuit, so the check valve behind the filter element can be omitted; and the Hall switch is non-contact, more reliable and longer life. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a schematic diagram of the water path of a water purifier in the prior art.

[0008] Figure 2 It is a schematic diagram of the waterway of the utility model. DETAILED DESCRIPTION

[0009] See attached Figure 1 . In the prior art, raw water enters the waterway from the inlet 1, passes through the pre-filter 2, the solenoid valve 3, and the booster pump 4, and enters the RO filter 5. Then the wastewater is discharged from the wastewater outlet 6, and the clean water is provided to the user through the check valve 7 and the pressure switch 8 through the mechanical faucet 9. Among them, a closed pipeline is formed between the check valve 7 and the faucet 9, and the pressure switch 8 provides a control signal according to the pressure change of this pipeline to control the start and stop of the solenoid valve 3 and the booster pump 4. Of course, there is also a reflux waterway in the prior art, which has little to do with the main purpose of this patent and is omitted here.

[0010] See attached Figure 2 Compared with the prior art, the present embodiment is different in that the mechanical faucet 9 is replaced by the intelligent faucet 10, and the check valve 7 and the pressure switch 8 are omitted in the water path. The intelligent faucet 10 has a main body 11 and a handle 12, and water flows out of the faucet when the handle 12 is turned on; at the same time, a magnetic element is provided on the handle 12, and a Hall switch is built into the faucet main body 11; when the handle 12 is turned on, the Hall switch senses the change in the magnetic field, thereby providing a control signal to control the start and stop of the solenoid valve 3 and the booster pump 4.

Claims

1. A water purifier controlled by a tap, comprising a filtering system and a water outlet tap, wherein the filtering system comprises a control unit and one or more filter elements, and the control unit controls the start and stop of the entire filtering system, thereby purifying water through the filter element; characterized in that: The last filter element in the filtration system is directly connected to the faucet; a magnetic element is installed in the handle of the faucet, and a Hall switch is built into the faucet body. The Hall switch senses the movement of the magnetic element in the handle and transmits the signal to the control unit.
