Abstract: A mobile toilet with a ventilation and heat-dissipating device comprises a base and a main body. The base is connected to a bottom of the main body. Ventilation openings are disposed at positions of a lower half portion of a total height of the base and the main body connected together. An exhaust port and a canopy device are disposed at predetermined positions of a top of the main body. The lower ventilation openings naturally guide air into the mobile toilet according to a chimney effect, so that hot air and stinks in the mobile toilet flow upwardly to the exhaust port, thereby heavily exhausting the hot air and the stinks and cooling the mobile toilet by a lot of natural convection. The canopy device blocks external rainwater.

Abstract: An improved mobile toilet structure may include a base, four side bars, four sleeve tubes, four panels and a lid. The base has four threaded holes at four corners of the upper side of the base, and a vertical exhaust pipe at one side of the rear portion of the base. The side bar has a first threaded portion on its upper end and a second threaded portion on its lower end. The sleeve tube has an opening on one side and the two margins of the opening extend outwards and form two wing-like structures. Among the four panels, the front one has a board installed in the panel that can be opened and closed, whereas all others may have transom windows opened at their upper portions. The lid is integrally molded, with its size and shape determined by the base.

Abstract: The solar powered fan for a portable enclosure includes an electrical fan, which is pivotally mounted within the interior region of a portable edifice, such as that associated with a portable toilet facility. The pivotal mounting of the fan allows for selective user adjustment of the angular position of the fan with respect to the roof of the housing. Mounted on the roof, exterior to the enclosure, is a hollow housing having at least one solar panel mounted to an upper surface thereof. The solar panel charges a rechargeable battery received within the hollow housing which, in turn, is in electrical communication with the electrical fan.

Abstract: A portable restroom facility has a housing. The housing has a door opening for entering and exiting the housing. A removable waste storage container is stored within the housing for holding bodily waste. When the removable waste storage container is full or partially full, the removable waste storage container can be removed and a new clean removable waste storage container can be inserted into the housing. Thus, a waste drainage truck does not need to visit each facility and drain each portable restroom facility.

Abstract: A portable toilet stool or bowl, upper opening of which is effectively closed by an air-curtain formed by currents of air flowing all over said opening, so that the smell of feces evacuated into the stool does not freely rise into the air from the upper opening, and the smell is forcibly subjected within the stool, to deodorizing and/or decomposition, and discharged into the air or circulated within the stool for a predetermined period of time.

Abstract: A portable and mobile toilet includes a case for removably placing a bowl therein, and four elongate walls and an upper cover collapsibly combined together. The case, the bowl and the upper cover have an outer layer and an inner layer to form an inner hollow cavity for a gas to fill therein when the toilet is to be combined together for use. The upper cover is placed on the four walls when in use, and is closed on the case when collapsed. The four walls are made of a flexible opaque material, able to be rolled up and stored in the case when collapsed. Ropes and nails are provided to secure the upper cover and the case stably to keep the toilet secured on the ground.

Abstract: The waste material holding tank located within a portable, outdoor toilet cabana is vented to atmosphere by a vent pipe extending upwardly from the tank to the roof of the toilet cabana. A small, electrical blower fan is mounted upon the upper, open end of the vent pipe for sucking air from the holding tank and blowing the air to outside atmosphere. A solar energy panel is mounted upon the roof of the cabana near the fan and is electrically connected to the fan. The panel generates electrical energy in response to a predetermined level of sunlight for electrically energizing the fan. Thus, the fan circulates air through the holding tank during the items that the sun is shining upon the cabana, to reduce the solar heat build-up in the holding tank for reducing the generation of noxious odors caused by heat induced reactions in the waste material in the tank.
