Homemade Vehicle Mobile Toilet

Homemade vehicle mobile toilets can be achieved through methods such as transforming laundry detergent bottles, modifying car center consoles, and refitting car armrest boxes with hoses. You can also pay attention to relevant patented products, but it is important to note issues such as sealing and safety.

1. Transforming a Laundry Detergent Bottle into a Urinal
   Use a discarded laundry detergent bottle as a container and prepare tools such as an electric drill, water pipes, nuts, and glue. First, drill a hole in the center of the bottle cap that matches the diameter of the water pipe, install a direct connector, and tighten it firmly. Then, insert one end of the sewer hose into the nut, apply glue to the other end, and insert it into the connector. Add a gasket inside and tighten the cap. Next, apply glue to the edge of the connector and connect it tightly with the drainage hose. Finally, screw the modified bottle cap back onto the bottle. The key step is the sealing test: Pour mineral water into the bottle, flip it over, and observe for leaks. Confirm that there are no leaks before using it. This method is low-cost and simple to operate, but it has limited capacity and is suitable for short trips or emergencies.

2. Modifying a Car Center Console into a Mobile Urinal
   This requires drilling a hole directly in the handle position of the car center console and inserting a transparent plastic tube for fixation. However, this method has high risks: Drilling may damage the vehicle's electrical circuits or structure, and if the plastic tube is not firmly fixed, it may easily lead to liquid leakage, polluting the car's interior environment. In addition, unauthorized modification of the car center console may violate relevant regulations. It is not recommended for non-professionals to attempt this. If necessary, other safer solutions should be prioritized.

3. Refitting a Car Armrest Box with a Hose into a Vehicle Urinal
   Drill a hole in the bottom of the armrest box, extend the hose connected to the water cup into the bottom of the car, insert the end into a discarded plastic bottle filled with filter materials such as sponges, and fix it under the car pedal with tape. The core advantage is relatively good concealment, but it is important to note: The drilling position should avoid important vehicle circuits; the filter materials should be replaced regularly to prevent clogging; the length of the hose should be precisely calculated to avoid excessive length causing entanglement or insufficient length preventing drainage. After modification, test the drainage efficiency to ensure that urine can flow smoothly into the bottle without backflow.

4. Paying Attention to Patented Products
   Seres Automobile Co., Ltd. has applied for a utility model patent for a "Vehicle Urinal and Vehicle". The device consists of a urinal body and a slide rail assembly. It is usually hidden under the seat and can be pulled out for use in emergencies and then pushed back in. However, the official has not yet clarified whether it will be installed in mass-produced vehicles, so you can continue to pay attention to its developments.

General Precautions: All solutions should prioritize testing for sealing to avoid liquid leakage that could damage the vehicle's interior or electrical circuits. For long-term use, regularly clean the container and pipes to prevent bacterial growth. When driving, it is recommended to fix the container in a stable position such as under the seat to reduce the risk of shaking. If conditions permit, you can purchase a finished vehicle urinal, which is designed to be more ergonomic and safer.
