Wenjie Mobile Toilet Principle

The principle of the Wenjie mobile toilet is based on the utility model patent for 'Vehicle-mounted Toilet and Vehicle'. It achieves hidden storage and waste treatment through a mechanical structure, with the core being a 'track-seat-toilet' three-in-one design combined with waterless flushing or biodegradation technology.

1. Mechanical Structure: Hidden Storage and Rapid Opening/Closing

The mechanical structure of the Wenjie vehicle-mounted toilet consists of a toilet body and a dual-rail assembly. The fixed rail is embedded in the vehicle roof, while the sliding rail is rigidly connected to the bottom of the seat, forming a 'track-seat-toilet' three-in-one structure. When in use, the user gently pulls the handle, and the toilet smoothly slides out from under the seat along the track in just 3 seconds; after use, it is pushed back into place, leaving no visible marks on the cabin surface. This design solves the issues of space occupation, tipping, and leakage associated with traditional mobile toilets through hidden storage, making it particularly suitable for long-distance self-driving trips, highway traffic jams, and outdoor camping scenarios.

2. Waste Treatment: Waterless Flushing or Biodegradation Technology

The waste treatment technology of the vehicle-mounted toilet falls into two categories:

1. Waterless Packaging Type: A mechanical sealing device pushes feces into a dedicated plastic bag and seals it using heat-sealing technology to prevent odor leakage. This technology does not require a water source and is suitable for environments with limited resources.
2. Foam Sealing Type: Foam generated by a foaming liquid mixture lubricates the descent of feces while blocking odor diffusion channels. The lubricating effect of the foam reduces friction between the feces and the inner wall of the toilet, making cleaning easier.

3. Environmental Control: Ventilation and Deodorization Modules

To ensure a pleasant user experience, the vehicle-mounted toilet integrates an environmental control module, including a ventilation system and a deodorization device. The ventilation system expels odors through negative pressure principles, preventing their accumulation in the cabin; the deodorization device may use activated carbon filtration or chemical neutralization technology to further purify the air.

4. Technological Advantages: Integration of Privacy, Cleanliness, and Safety

Compared to simple solutions like folding plastic buckets on the market, the Wenjie vehicle-mounted toilet achieves true hidden storage:

• No Foot Space Occupation: The toilet is fully stored under the seat, without affecting in-car activities.
• No Odor or Residue: The sealing design and environmental control module ensure no odor leakage after use and thorough waste treatment, avoiding garbage residue.
• Privacy Protection: The hidden structure and rapid opening/closing function safeguard user privacy, making it particularly suitable for emergency use in public scenarios.

This design achieves the core functions of a mobile toilet in a limited space through the synergy of mechanical structure, waste treatment, and environmental control, providing an innovative solution for vehicle-mounted sanitation facilities.
