KEMFLO INTERNATIONAL CO., LTD.

A remote control mechanism and a remote controller are provided, including a control assembly, a packaging assembly provided with a packaging space to receive the control assembly, and a triggering assembly. The triggering assembly includes a handle, a magnetic member, and a magnetic induction element. The handle is rotatably connected to the packaging assembly, the magnetic member is mounted on the handle, and the magnetic induction element is provided in the packaging space. The handle has a triggering position and an off position. When the handle is located at the triggering position, the magnetic induction element is located out of a magnetic induction area of the magnetic member, and the control assembly generates a control signal. When the handle is switched to the off position, the magnetic induction element is located within the magnetic induction area, and the control assembly stops generating the control signal.

A composite filter cartridge is adapted to filter raw water to produce purified water, and includes an inner carbon tube, an outer carbon tube, a first end cap, a second end cap, and a plurality of resin granules. The inner carbon tube defines a water outlet channel adapted to output the purified water. The outer carbon tube is concentric with the inner carbon tube, and is spaced apart from the inner carbon tube. The first and second end caps respectively limit two ends of the inner and outer carbon tubes. The first end cap closes an end of the water outlet channel. The second end cap has a water outlet communicating with the water outlet channel. The second end cap cooperates with the inner carbon tube, the outer carbon tube, and the first end cap to define a resin granule accommodation space where the resin granules are accommodated.

A water filter includes a cover assembly having a filtering head, a filter bottle assembly having a filter bottle, and a connecting device connecting the filtering head and the filter bottle. The connecting device includes a fastening module, a rotation wheel mechanism, a rotary member, and a pulling member. The fastening module includes a tightening strap, a pivot seat, and multiple elastic support pieces. The rotation wheel mechanism includes a drive module and a rotation wheel engaging the drive module so that the rotation wheel and the drive module are linked. The pulling member presses the tightening strap and the pivot seat. The pulling member encircles the elastic support pieces and is wound around the rotation wheel so that the pulling member is scrolled by rotation of the rotation wheel, and the elastic support pieces are compressed by the pulling member.

A water filter includes a filtering head, a filter bottle assembly, a filter element, a switching device, and a quick release device. The filtering head has a water inlet, a water outlet, and multiple embedded slots. The filter bottle assembly includes a filter bottle removably mounted on the filtering head. The filter element is mounted in the filter bottle and provided with a flow channel. The switching device is mounted on the filtering head and includes a handle and a control shaft provided with a connecting hole. The quick release device includes multiple movable modules mounted in the embedded slots, a push member mounted on the filter bottle, and a snap-fit member mounted on the push member. In assembly, the movable modules are positioned between the push member and the snap-fit member so that the filter bottle is locked on the filtering head.

A backflow-preventing filter module includes a filter unit and a backflow-prevention valve. The filter unit includes a filter cartridge that has a connector formed with an annular groove, and a filter shell that defines an accommodating space and that includes a connecting head. The connecting head has an inner surrounding wall defining an annular slot. The backflow-prevention valve is sleeved on the connector, and has a fixing portion disposed in the annular groove and an abutting portion moveable between an open position, where a distal end of the abutting portion is pushed by water to be away from the inner surrounding wall so that the annular slot is not blocked, and a closed position, where the abutting portion is expanded to abut the distal end thereof against the inner surrounding wall, thereby blocking the annular slot.

A purified water supply pipeline system is provided. Source water flows from a source water inlet to a front filtration module, an inlet solenoid valve, a booster pump, and a main filtration module and is separated into purified water and waste water. The purified water flows through a first one-way valve to a rear filtration module and then flows to a purified water pipeline, on which a water outlet faucet is mounted. The waste water flows to a waste water pipeline, on which a waste water throttling element and a waste water outlet are disposed. The purified water also reflows to the main filtration module through a switch solenoid valve and the booster pump, to form a reflow pipeline. The purified water supply pipeline system balances concentration difference on both sides of the main filtration module. Accordingly, quality of the purified water and user experience are improved.

A control method of a control system for controlling water purification module for processing water on two sides of a reverse osmosis membrane. The control system has a water purification module and a control module. The water purification module has a preliminary filter and a reverse osmosis filter. The control module regularly controls the purification and the drainage of the water purification module, and solves the problem that the TDS value of the water on both sides of the reverse osmosis membrane is too high after the water purifier is on standby for a period of time. The control system regularly drains high concentration water on both sides of the reverse osmosis membrane to improve water purification efficiency.

A buffering device for a filter bottle. The buffering device is disposed on a body of the filter bottle and has a sidewall, a top, a bottom, and a chamber. The top of the buffering device is moveable up and down along the sidewall of the buffering device. The chamber is formed between the sidewall, the top, and the bottom of the buffering device, and does not communicate with an interior of the filter bottle. The chamber communicates with an exterior via an air gap for air exchange. A filter bottle having the buffering device can provide a function of anti-water-hammer, can reduce a risk of leakage at a connection between the filter bottle and a valve head, and can provide an anti-freeze effect to reduce a risk of rupture of the filter bottle.

A regeneration system is provided for regenerating at least one regeneration container which has an accommodation space for confining therein an inactive ion-exchange resin. The regeneration system includes a flow-path control device, a first tank, a second tank, a first filtration element, a third tank, and a second filtration element. The flow-path control device is actuated to be operable in a first circulation state and a second circulation state. The first tank is switchable to be in fluid communication with the accommodation space. The second tank is switchable to be in fluid communication with a first circulation path. The first filtration element is disposed to filter a first liquid in the first circulation path. The third tank is switchable to be in fluid communication with the accommodation space. The second filtration element is disposed to filter a third liquid in a second circulation path.

A water filter includes a filtering head, a filter bottle assembly, a switch member, and a quick release device. The filtering head includes a flow channel module. The filter bottle assembly includes a filter bottle. The quick release device includes a press lever, two links, and two push members. When the press lever is pivoted, the two links and the two push members are driven by the press lever to move the filter bottle simultaneously so that the filter bottle is mounted on or detached from the filtering head quickly. A switch member functions as a waterway switch to control a water supply of the filtering head and functions as a locking mechanism for locking or unlocking the quick release device.
