Car Modification Portable Toilet
There are relevant cases of car modification portable toilets, with Seres and Jishi Automobile having launched related products or accessories.
Seres Automobile Case
On April 10, 2026, Seres Automobile obtained formal approval from the National Intellectual Property Administration for its utility model patent titled 'Vehicle-mounted Toilet and Vehicle,' with the authorization announcement number CN224104011U. Its vehicle-mounted toilet adopts a slide-rail design and offers numerous advantages.
- Reasonable Space Utilization: It is completely hidden beneath the driver's and passenger's seats when not in use, occupying no interior space and not detracting from the interior aesthetics. This design fully considers the limited space inside a vehicle, cleverly integrating the portable toilet function without affecting the normal use and appearance of the vehicle.
- Convenient Use: It can be pulled out with one button when in use and pushed back into place after use, making it simple and easy to operate for both drivers and passengers.
- Comprehensive Functions: It is equipped with a 5L sealed waste collection tank that effectively collects waste and prevents odor emission; a negative-pressure deodorization system that further eliminates odors and keeps the interior air fresh; a constant-temperature heating function that enhances comfort, especially in cold environments; and the provision of disposable toilet bags and a foldable privacy curtain ensures hygiene and protects user privacy.
Jishi Automobile Case
As early as 2024, Jishi Automobile launched a vehicle-mounted toilet accessory. This accessory is placed in the central storage compartment and can be used by simply lifting the lid and placing a toilet seat cover. However, the founder of Jishi admitted that this is essentially an emergency accessory, indicating that its functionality and user experience may be relatively simple, primarily meeting the need for toilet use in emergency situations. Compared to Seres Automobile's vehicle-mounted toilet, it may have certain gaps in terms of comfort and functional completeness.
