Tangtou Mobile Toilet

Admin September 20, 2026

There is patent information about a mobile ecological non-flushing eco-friendly toilet applied for by Wang Weiguo in the Tangtou area, but this patent right has expired. Currently, no other specific information about mobile toilets in the Tangtou area has been obtained.

Basic Patent Information

There was once a patent for a mobile ecological non-flushing eco-friendly toilet in the Tangtou area. The applicant was Wang Weiguo, with the application number cn201520004273.3 and the authorization announcement number cn204418726u. However, due to non-payment of the annual fee, this patent right expired on March 1, 2017. This means that from a legal perspective, this patent is no longer protected, and the relevant technology may have entered the public domain, allowing others to freely use this technology for production, improvement, and other activities.

Toilet Structure Features

This mobile ecological non-flushing eco-friendly toilet consists of two restrooms, which can to some extent meet the usage needs of more people and improve usage efficiency. It has a toilet bowl at the bottom, with a cavity and a stirring wheel set below the toilet bowl. The stirring wheel may help with the preliminary treatment of excrement, making it more evenly distributed or better mixed with subsequently added substances. There is also a microbial culture pool inside the toilet, which is connected to the cavity below the toilet bowl through pipelines. Microorganisms have unique advantages in treating excrement. They can decompose the organic matter in excrement and convert it into relatively harmless substances, achieving non-flushing treatment and reducing water consumption. In addition, the toilet is equipped with an exhaust pipe, a controller, and a heating device. The exhaust pipe can promptly vent the odors generated inside the toilet to keep the air fresh. The controller may be used to control the operation of the entire toilet system, such as the rotation of the stirring wheel and relevant operations of the microbial culture pool. The heating device may function in cold environments to ensure the activity of microorganisms and the normal operation of the entire system.

Current Situation Description

Currently, apart from the above patent information, no other specific information about mobile toilets in the Tangtou area has been obtained, such as whether this patented technology has been practically applied locally and whether there are other types of mobile toilets.
