Portable Water-Taking and Purifying Cup with Built-In Pump and Quality Detector

The problem

When users need drinking water away from treated taps, carrying a hand-pump filter, spare bottles and testing strips means managing several loose items. Manual pumping tires the hands, and without a way to check the water after filtering, users cannot tell if the filter is still working or if the source water was too dirty for the element to handle. Packing all these parts separately also takes up room in a backpack or vehicle.

The solution

1. One cylindrical shell divided into a lower housing, a middle housing and an upper housing keeps every component together.
2. A detachable dirt blocker (funnel-shaped base, outer grid cover and filter screen) attaches to the water inlet end of the inlet pipe, acting as a preliminary filter so large debris does not load the main element.
3. A DC booster pump in the lower housing draws water through the inlet pipe and pushes it into the filter element, removing the need for manual pumping.
4. A storage battery, mounted next to the pump behind a partition with positioning holes, powers the pump.
5. The filter element in the upper housing processes the water, and its outlet leads to a water outlet at the bottom of the upper shell.
6. A real-time water quality detector with a detection circuit board, a water inlet detection electrode, a water outlet detection electrode and an indicator light sits inside the casing. The electrodes measure conditions before and after the filter, and the light shows the result.

Who it is for

• Outdoor gear brands looking for a self-contained water purification device to add to their camping and hiking catalogs, since the single-shell layout reduces the parts a user must carry.
• Emergency preparedness suppliers that stock relief kits; the battery-powered pump works without municipal pressure, and the detector gives users a visible signal about the filtered water.
• Promotional product distributors sourcing branded travel accessories for corporate clients, because the cylindrical middle shell provides a surface for markings and the unit combines several functions.
• Wholesalers serving agricultural or field workers who draw water from open sources and need a preliminary dirt blocker to keep the main filter from clogging quickly.

How it works

The main parts

Operating steps

1. Submerge or place the dirt blocker into the water source. The funnel-shaped base, outer cover with grid and internal filter screen catch large particles.
2. Press the switch on the middle shell. The storage battery sends power to the DC booster pump.
3. The pump draws water through the water inlet pipe and pushes it into the water inlet of the filter element located in the upper shell.
4. Water passes through the filter element and exits via the water outlet at the bottom of the upper shell.
5. During flow, the detector operates. The water inlet detection electrode inserted at the filter inlet and the water outlet detection electrode inserted at the filter outlet send readings to the detection circuit board.
6. The indicator light connected to the circuit board lights up to show the water quality condition.
7. To recharge, connect a cable to the plug-in interface on the middle shell.
8. To clean the preliminary stage, detach the dirt blocker from the water inlet pipe.

Applications

Backpacking and trail hiking

Hikers collect water from streams where carrying a manual pump adds fatigue over long distances. The built-in DC pump runs on the internal battery, and the dirt blocker keeps leaves and sediment out of the main filter so the element lasts longer between replacements.

Disaster relief staging areas

Relief workers often set up near rivers or flooded zones where tap infrastructure is down. The compact cylindrical shell fits into supply crates easily, and the indicator light lets teams see whether the water passing through the filter meets the expected condition before distributing it.

Agricultural field work

Farm crews working in remote fields draw from irrigation canals or ponds that contain suspended soil. The detachable dirt blocker handles this heavy particulate load first, reducing how often the crew needs to change the main filter element during a workday.

International travel and rural tourism

Travelers visiting regions with uncertain tap supplies can use the cup to process local water instead of buying bottled water constantly. The charging interface allows the battery to be topped up from standard USB adapters in hotels, keeping the pump ready for day trips.

Where it is less suitable

• High-volume group base camps - the unit is sized as a personal cup; groups needing liters per minute require larger pump systems.
• Saltwater desalination - the patent describes a filter element and dirt blocker, not a reverse-osmosis membrane rated for seawater.
• Mains-pressure plumbing integration - this is a standalone portable device, not an inline household filter housing.
