Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically to a water purifier system with a water outage self-protection function. Background Technology

[0002] As people's living standards improve, their requirements for drinking water quality are also increasing, and water purifiers are gradually becoming common equipment in homes and offices. Currently, most water purifiers on the market rely on a continuous supply of tap water to function properly. However, in actual use, water outages frequently occur, and when the water supply is restored, the tap water network often contains impurities, rust, sediment, and other contaminants.

[0003] If the water purifier lacks appropriate protective measures, this wastewater will flow directly into its interior, damaging critical components such as the filter cartridge. This can lead to filter blockage, shortened filter lifespan, and ultimately affect the purifier's normal operation and purification efficiency. Furthermore, wastewater entering the purifier may result in substandard purified water quality, posing a potential threat to the user's health. Frequent replacement of damaged filters also increases the user's operating costs.

[0004] While some technologies exist for water outage protection, they have many shortcomings. For example, most water purifiers on the market use low-pressure switches to prevent them from operating during water outages. However, the high-turbidity water remaining in the pipes can still enter the purifier when water supply resumes, causing filter clogging.

[0005] Some devices are complex in structure and expensive, making them difficult to promote and apply on a large scale. Utility Model Content

[0006] To address the aforementioned technical problems in the existing technology, this utility model proposes a water purifier system with a self-protection function in case of water outage, the specific technical solution of which is as follows:

[0007] A water purifier system with a water outage self-protection function includes a water purifier and a water circuit switching device;

[0008] The water circuit switching device has one inlet and two controllable outlets. The inlet is connected to the tap water inlet pipe, one outlet is connected to the water purifier's inlet, and the other outlet is connected to the system drain pipe. When there is no water in the inlet, one outlet switches to the closed state and the other outlet switches to the open state.

[0009] A one-way valve is installed at the water outlet of the water purifier, and the outlet of the one-way valve is connected to the system drain pipe.

[0010] Furthermore, the water circuit switching device includes a flow meter and a one-in-two-out solenoid valve connected to its signal. The inlet of the one-in-two-out solenoid valve is connected to the tap water inlet pipe, one outlet of the one-in-two-out solenoid valve is connected to the inlet of the water purifier, and the other outlet is connected to the system drainage pipe. The flow meter is installed in the tap water inlet pipe to obtain the water flow signal in the pipe.

[0011] Furthermore, the system also includes a pressure reducing valve, which is installed on the tap water inlet pipe upstream of the flow meter.

[0012] Furthermore, the water purifier is equipped with a first-stage filter element, an inlet solenoid valve, a booster pump, and a reverse osmosis membrane filter element connected in sequence, with a one-way valve connected to the reverse osmosis membrane filter element.

[0013] Furthermore, the first-stage filter element uses a composite filter element made of PP cotton fiber, activated carbon, and carbon rods.

[0014] Furthermore, a flushing solenoid valve is installed between the one-way valve and the reverse osmosis membrane filter element.

[0015] Furthermore, the water purifier is also equipped with a one-way valve high-pressure switch. One end of the one-way valve high-pressure switch is connected to the reverse osmosis membrane filter element, and the other end is connected to the first-stage filter element.

Attached Figure Description

[0017] Figure 1 This is a structural diagram of a water purifier system with a specific water outage self-protection function in this embodiment. Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1 As shown, this embodiment discloses a water purifier system with a water outage self-protection function. A water path switching device is set at the water inlet of the water purifier. This device can determine whether there is water flowing through and control the water to flow into the water purifier or directly into the drain pipe for discharge. A one-way valve is added at the water outlet of the water purifier before connecting to the drain pipe. The one-way valve is used to prevent backflow in the drain pipe.

[0020] Specifically, the water circuit switching device includes a flow meter and a one-in-two-out solenoid valve connected to its signal. The flow meter can obtain the water flow signal at the water inlet of the water purifier, which is used to determine whether there is water flow. The inlet of the one-in-two-out solenoid valve is connected to the water source pipe, one outlet is connected to the water purifier, and the other outlet is connected to the drain pipe. The solenoid valve controls the opening and closing of the two outlets according to the flow meter's judgment, thereby realizing water circuit switching.

[0021] When there is a normal water supply, the water purifier faucet is turned on, and the water flows through the flow meter. The flow meter senses that there is an inflow of water, and the whole system works normally. That is, water flows into the first-stage filter of the water purifier, the inlet solenoid valve, the booster pump, and the reverse osmosis membrane filter to produce pure water.

[0022] When the water supply is interrupted, the flow meter does not detect a water flow signal, the water purifier does not dispense water, and the entire machine enters standby mode.

[0023] When water returns, the flow meter detects the flow signal, and the system prompts the water purifier to enter self-protection mode. At this time, the water path is automatically switched via a one-inlet, two-outlet solenoid valve, and the water is discharged through the filter drain pipe. Simultaneously, a one-way valve is added to the filter drain pipe to prevent highly turbid water from entering the water purifier system.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. In this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal connection of two components or the interaction between two components, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Although the implementation process of this utility model has been described in detail above, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. All modifications and equivalent substitutions made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
