Vehicle-mounted Portable Toilet (Odor-proof Version)
The odor-proof version of vehicle-mounted portable toilets primarily achieves odor control through structural design, material selection, or complementary accessories, with some products incorporating patented technologies to enhance the user experience.

1. Basic Odor Control Design: Garbage Bag + Curing Agent Combination
Some products, such as the Heigou PP Folding Toilet, adopt an odor control solution using a "garbage bag + curing agent." Users need to place a dedicated garbage bag inside the toilet. After excretion, a curing agent is poured in for rapid solidification and deodorization. This design requires no subsequent cleaning; the sealed garbage bag can be disposed of directly after use, making it suitable for short-term emergency scenarios. The core of its odor control lies in the chemical neutralization effect of the curing agent, which effectively inhibits odor diffusion. However, the garbage bag needs to be replaced regularly, and the curing agent replenished.
2. Sealed Structure and Material Optimization
Multiple vehicle-mounted portable toilets achieve odor control through physical sealing and material upgrades. For example:
- Adult Portable Odor-proof Folding Toilet by Yiwu Shanbai Automotive Supplies Co., Ltd.: Features a sealing ring design that creates a closed space when the toilet lid and body are closed, preventing odor leakage, priced from 21.85 yuan;
- Outdoor Camping Folding Toilet by Taizhou Yingfeng Plastic Mould Co., Ltd.: Emphasizes material quality (e.g., high-density plastic) with a smooth, easy-to-clean surface that reduces residue buildup, while optimizing the structure to minimize gaps, priced from 9.5 yuan;
- Portable Folding Toilet by Yiwu Zhongheng Daily Necessities Co., Ltd.: Equipped with dual-seal odor control, featuring a silicone seal strip on the inside of the toilet lid and an optional deodorizing pack at the bottom of the body, priced at 47.8 yuan.
The odor control effectiveness of these products depends on their sealing and material stain resistance, making them suitable for medium- to long-term use. However, regular cleaning of residue inside the toilet is necessary to maintain performance.
3. Patented Technology: Integrated Deodorization System
Seres Automotive (parent company of AITO) has applied for a patent for a vehicle-mounted toilet that incorporates odor control into a hidden installation design. This patent utilizes a built-in deodorization module (e.g., activated carbon filtration or negative pressure suction system) to adsorb odors in real-time during excretion, addressing emergency needs in scenarios such as highway traffic jams. Its advantage lies in requiring no additional user operation, but it has not yet been mass-produced, and technical details (e.g., deodorization efficiency, maintenance cycle) require further verification.
Purchase Recommendations:
- For short-term emergencies: Prioritize garbage bag + curing agent type products for their portability and ease of use;
- For medium- to long-term use: Recommend sealed structure + stain-resistant material type products that balance odor control and durability;
- For high-end needs: Consider products with integrated deodorization patented technologies, but evaluate actual usage scenarios and costs.
