  • Publication number: 20250108320
    Abstract: 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.

  • Patent number: 12215041
    Abstract: 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.

  • Publication number: 20250018317
    Abstract: 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.

  • Patent number: 11820673
    Abstract: A water purifier includes a filter head, a flow channel control module, and a filter element. The flow channel control module includes a waterway board and a flow manifold. The waterway board is provided with a water flow channel. The flow manifold is provided with a first passage and a second passage. When the flow manifold is driven by the filter element and rotated relative to the waterway board to a first position where the first passage is connected to the water flow channel, the flow channel control module is switched to a first flow channel waterway mode (or filter mode). When the flow manifold is driven by the filter element and rotated to a second position where the second passage is connected to the water flow channel, the flow channel control module is switched to a second flow channel waterway mode (or replacement mode).

  • Patent number: 11697081
    Abstract: A water purifier structure includes a container assembly and a buffer unit mounted in the container assembly. The container assembly includes a housing and a cap unit. The housing has a first receiving section and a second receiving section. The second receiving section of the housing is provided with a retaining portion. The buffer unit is mounted in the second receiving section of the housing and includes a positioning ring secured in the retaining portion of the housing, and a cushioning member mounted in the positioning ring. The cushioning member is elastically movable in the positioning ring. When the cushioning member is compressed by a force, the cushioning member is contracted and elastically deformed toward the second receiving section of the housing, to form a buffering force.

  • Publication number: 20130220899
    Abstract: A filter cartridge monitor (1) includes a body (2), a shaft (3) extending downward from the body, a circuit board (23) installed in the body (2), an indicator (21) electronically connected to the circuit board (23), a floating component (4) that can move along the shaft (3), and at least one sensor (31) installed on the shaft (3) that is electronically connected to the circuit board (23). When water is poured into the inner jug (52), the floating component (4) will float and move due to its buoyancy in the water. The movement of the floating component (4) can be regarded as the volume of water that passes through the filter cartridge (53), which can be recorded by the circuit board (23) of the monitor (1).
