BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will be described in detail with reference to the accompanying drawings, in which,

FIG. 1 is a perspective schematic view of a portable closet of the present invention;

FIG. 2 is a cross-sectional view of the portable closet of the present invention; and

FIG. 3 is a cross-sectional view of a cover of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1, the present portable closet with a heater comprises a tub 1, a cover 2 detachably covering the tub 1, a receiving bag 3 placed within the tub 1 for receiving excrement and urine of users. The receiving bag 3 could be disposable and be made of non-woven materials. The receiving bag 3 could be provided with a sponge 5 and activated carbon therein, in which the sponge 5 is used to absorb water in the excrement and urine, while the activated carbon is used for sterilization and deodorization.

As shown in FIG. 3, the cover 2 includes a toilet seat 21 and a lid 20. The toilet seat 21 is provided with an aperture for the excrement and urine entering into the tub 1. The lid 20 is pivotably connected to the toilet seat 21 beside the aperture, for selectively opening the aperture. At least two hooks 22 are provided on a lower surface of the toilet seat 21 around the aperture, for hanging the receiving bag 3. Between the lid 20 and toilet seat 21, a fastener 23 is provided for fastening the lid 20 with respect to the toilet seat 21. The cover 2 is made of thermal conductive materials, and is provided with a heater 4 in its lower surface. The heater 4 is composed of an aluminum sheet covered with rubber, a ceramic heater film, a temperature sensor, a circuit and a battery consequently. The heater could heat the toilet seat 21 intermittently and work for 1 hour with the battery, to enable to keep the temperature of the toilet seat 21 at a suitable level. A charging port 24 is provided at an edge of the toilet seat 21, through which the battery could be charged. The charging port 24 could be a universal serial bus (USB) port or a common socket or a combination of the formers. Thus, the battery of the heater could be charged by means of a USB cable or a charger 17. Furthermore, a light emitting diode (LED) display 26 could be provided on an edge of the toilet seat 21 for displaying the status of the heater 4.

As shown in FIG. 2, the tub 1 is composed of a bottom sheet 10 and a plurality of side sheets 11, and thereby a cavity 12 for receiving excrement and urine could be formed within the tub 1. The bottom sheet and the side sheets could be made of plastics. Adjacent two side sheets 11 engage with each other in a manner of a concave-convex structure. In another word, a side edge of a side sheet is provided with several concave regions, while an adjacent side edge of the other sheet is provided with matching convex portions. The concave regions and the matching convex portions engage with each other to enable the two adjacent side sheets attach to each other. The bottom sheet is provided with grooves at edges thereof, and each side sheet is inserted into a groove to be fixed to the bottom sheet.

The receiving bag 3 is hung from the hooks 22 within the cavity 12. A reusable plastic bag 15 could cover the receiving bag 3, to avoid leakage and decrease an offensive odor. A supporting base 14 is provided within the tub 1 and could be made of corrugated paper. The supporting base 14 is divided into three compartments vertically, in which an upper compartment is hard enough for supporting the receiving bag 3 and the plastic bag 15; a middle compartment is used to contain spare receiving bags and plastic bags, and each of the spare receiving bags could contain a sponge 5 and activated carbon therein in advance; and a lower compartment is used to contain the charger 17 or USB cable by virtue of which the battery of the heater could be charged.

The portable closet could further be provided with a rod 13, and a through hole 16 at matching locations in two opposite side sheets 11 for supporting the rod 13. Each end of the rod 13 is provided with two washers. The washers are used to fix the end of the rod within the through hole from inside and outside of a side sheet. The rod 13 is located in the tub 1 near a side sheet, to not interfere with the supporting base 14. The rob 13 is used to support toilet tissues 18. A slit 25 is formed through the toilet seat 21 aligning with the rob 13 to enable the toilet tissue 18 to pass through, as shown in FIG. 1.

Before the present portable closet is used, the toilet seat 21 is opened firstly, and a receiving bag 3 is hung from the hooks 22 and provided with a sponge 5 and activated carbon therein. Then, a plastic bag 15 is placed outside the receiving bag 3 and is also hung from the hooks. Subsequently, the toilet seat 21 is closed, and thereby the plastic bag 15 and receiving bag 3 is contained within the cavity 12 and supported on the supporting base 14. A user could open the lid 20 to use the portable closet. After used, the receiving bag 3 could be taken out, sealed and placed to a suitable place for collection. Then, a new receiving bag 3 could be placed in the plastic bag 15, to enable to be used next time.

In winter, users could turn on the heater 4 to warm up the toilet seat 21. Furthermore, a switch could be provided for the heater, and the heater could only works after being supplied with power. Therefore, it would be of safety for the users. The heater 4 is flush with the toilet seat 21 to make it comfortable for the users to sit thereon.

Although the description of the present invention is made with reference to the preferred embodiments, the present invention is not limited to these embodiments. Various modifications and changes can be made to the invention by those skilled in the art without departing from the spirit and scopes of the present invention.
