Disclosed herein is a liquid container having a hollow handle located adjacent to the center of mass of a container filled with liquid. With the hollow handle located adjacent to the center of mass, the total bending moment exerted on a user's wrist is drastically reduced. The container may contain a reservoir tank to retain any type of liquid. Further, the handle is hollow such that liquid may flow from the upper chamber to the lower chamber through the handle. In some embodiments, the handle is structured to house a filtration system. In some embodiments, the reservoir is structured to house a filtration system. A liquid may pass through the filtration system to become treated before being stored in the lower chamber.

A convenient hydrogen rich water cup includes a water cup body, wherein the bottom of the water cup body is equipped with a built-in slot, wherein a wireless power socket is embedded. The water cup body is internally equipped with a hydrogen rich water generation module, which is electrically connected to the wireless power socket. This invention patent provides power to the hydrogen rich water generation module through a wireless power socket, simplifying the structure of the hydrogen rich water cup, and can adapt to the currently popular wireless charger to power it, greatly reducing its manufacturing cost and making it convenient to carry and use, which is conducive to the widespread application of the product. Moreover, using the embedded slot to fix the wireless power socket can improve the connection stability between the wireless power socket and the water cup body, making the product performance more stable and durable.

The present invention relates to a filtration device comprising an inlet funnel with a cartridge seat, a filter cartridge placeable in the cartridge seat, and a sensing apparatus comprising sensing means for measuring at least one water characteristic. The sensing apparatus comprises an electrical circuit with a control gap and the filter cartridge comprises a bridging element, wherein the bridging element is arranged such that it electrically closes the control gap when the filter cartridge is located in the cartridge seat.

An eco-friendly water filtration apparatus. The apparatus may comprise a lid comprising openings that allow water to flow into the apparatus, and an enclosure that is open at one end and comprises openings at the opposing end that allow water to flow out of the apparatus. The enclosure may be configured to receive a pod of activated carbon, while allowing removal of the pod, and the lid may be configured to attach to and detach from the enclosure at the enclosure's open end.

An ultraviolet disinfectant head attachable to a fluid container having a central axis for disinfecting a fluid housed in a cavity of the fluid container. The system comprises an ultraviolet light emitting diode (UV-LED) having a principal emission axis and a lens (e.g. a diverging lens) having a primary optical axis. The lens is located and/or oriented to receive radiation from the UV-LED and direct refracted radiation toward the cavity of the fluid container. The refracted radiation may be diverging when it reaches a fill plane of the fluid container.

The invention relates to container bodies configured to be used in filter-as-you-pour systems, where filtering is achieved as the user pours water from the container. Such container bodies may have an undivided internal storage volume, so as to not include a reservoir compartment for unfiltered water. They may be part of systems configured to filter water both as water is introduced into a container body of the system and as water is poured from the container body of the system. The filter assembly may be attached to the container body at a location proximate the outlet of the system. Filter media of the filter assembly may comprise an activated carbon textile material that presents a curved surface to water passing through the filter assembly. The container body may be configured as a pitcher, carafe, water bottle, jug, or other shaped container.

A reusable water filter cartridge comprises a housing having a water-permeable base and a body extending from the base. The base and the body define a cavity for receiving filter media. There is a water-permeable lid which is removably securable to the housing via interlocking connectors on the lid and the housing. The lid is securable to the housing by rotating the lid relative to the housing in a first rotational direction to engage the connectors on the lid and the housing with each other. The lid is releasable from the housing by rotating the lid relative to the housing in a second rotational direction which is opposite to the first rotational direction to disengage the connectors on the lid and the housing from each other. Water to be filtered enters the housing via the lid, passes through the filter media contained in the cavity, and exits the housing via the base.

A system includes memory banks that store data and a data path coupled to the memory banks that transfers the data. The system also includes a latch that gates the data path based on a clock signal in the system. The system further includes interface circuitry coupled to the data path that sends an instruction to the memory banks to transmit the data on the data path in response to receiving a first rising edge of the clock signal. The interface circuitry also outputs gated data in response to receiving a second rising edge of the clock signal. The latch gates the data path to store the gated data in response to receiving a falling edge of the clock signal.

In one example, a fluid container includes a reservoir that includes a reservoir wall. A cover is configured to engage the reservoir, and the cover includes a spout configured and arranged for fluid communication with the reservoir, and the spout is disposed at one end of the cover. The fluid container also includes a filter cage configured to releasably engage the cover in a location near the spout. When the filter cage is engaged with the cover, and the cover is disposed on the reservoir, a small gap is defined between the front of the spout and the front of the filter cage.

A solution for treating a fluid, such as water, is provided. The solution determines an ultraviolet transparency of a fluid before or as the fluid enters a disinfection chamber. In the disinfection chamber, the fluid can be irradiated by ultraviolet radiation to harm microorganisms that may be present in the fluid. One or more attributes of the disinfection chamber, fluid flow, and/or ultraviolet radiation can be adjusted based on the transparency to provide more efficient irradiation and/or higher disinfection rates.
