DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] With reference to FIG. 1, a portable defecation assistive equipment in accordance with the present invention comprises a collecting receptacle 10, a guiding cover 20, and a pump motor 30.

[0023] With reference to FIGS. 1 to 2, the collecting receptacle 10 is a container having an inner space and has an opening 11, a handle 12, an air suction pipe 13, and a fastening sheet 14. The opening 11 is formed on an end of the collecting receptacle 10 and communicates with the inner space of the collecting receptacle 10, and a fastening annular flange 111 extends around an outer edge of the opening 11. The handle 12 is formed on a top surface of the collecting receptacle 10. The air suction pipe 13 is mounted on the top surface of the collecting receptacle 10 and communicates with the inner space of the collecting receptacle 10. The fastening sheet 14 is formed on the top surface of the collecting receptacle 10 and is adjacent to the handle 12.

[0024] With reference to FIGS. 1 to 3, the guiding cover 20 is a resilient structure, is connected to the collecting receptacle 10, and has a guiding hole 21, a fastening groove 22, and a wing 23. The guiding hole 21 is formed through the guiding cover 20 and communicates with the opening 11 of the collecting receptacle 10. The guiding hole 21 has two openings and a diameter of the guiding hole 21 is gradually increased towards one of the two openings distal from the opening 11 of the collecting receptacle 10. The fastening groove 22 is radially concaved around an inner surface of the guiding hole 21 of the guiding cover 20 and has a slot disposed around an inner surface of the fastening groove 22. The fastening groove 22 communicates with an exterior environment via an end of the guiding cover 20 adjacent to the collecting receptacle 10 and the slot of the fastening groove 22 is disposed around and engages with the fastening annular flange 111 of the collecting receptacle 10.The wing 23 is formed around an outer edge of one of the openings of the guiding hole 21 that is bigger in diameter than the other opening of the guiding hole 21.

[0025] With reference to FIGS. 1 and 2, the pump motor 30 is connected to the collecting receptacle 10 and has a power source, an electric cable 31, a switch 32 and a gas tube 33. The power source is mounted in the pump motor 30 to provide the electricity for the operation of the pump motor 30. The electric cable 31 is electrically connected to the power source of the pump motor 30. The switch 32 is mounted on an end of the electric cable 31 to switch on or off the pump motor 30. The switch 32 is selectively fastened with the fastening sheet 14 of the collecting receptacle 10. Two ends of the gas tube 33 are respectively connected to and communicate with the pump motor 30 and the air suction pipe 13 of the collecting receptacle 10. In a preferred embodiment, the present invention adopts a pump motor 30 that has a low pumping rate to limit the pumping pressure of the pump motor 30 to be smaller than or equal to 550 mmHg.

[0026] With reference to FIGS. 1 and 3, when the present invention is in use, the guiding hole 21 and the wing 23 of the guiding cover 20 are attached closely to the buttock of the user, and the switch 32 is switched on to activate the pump motor 30. The pump motor 30 starts to pump air from the inner space of the collecting receptacle 10, and the pressure in the collecting receptacle 10 is continually dropped in the pumping process. A negative pressure status is formed in the collecting receptacle 10, an attraction effect caused by the negative pressure can help the user to defecate, and excreted wastes of the user are flowed to the inner space of the collecting receptacle 10 via the guiding hole 21 of the guiding cover 20 and the opening 11.

[0027] The present invention combines the pump motor 30 and the collecting receptacle 10. The pump motor 30 pumps air from the collecting receptacle 10 that is in an air tight condition. When the pressure in the collecting receptacle 10 is smaller than the atmospheric pressure, the negative pressure status is formed in the collecting receptacle 10. The attraction caused by the negative pressure condition can help the user to defecate and the excreted wastes of the user are guided into the collecting receptacle 10 via the guiding hole 21 of the guiding cover 20 and the opening 11. The guiding cover 20 of the present invention is a resilient structure and has a wing 23 radially formed around the guiding cover 20. The wing 23 is thin and soft and can seal the buttock of the user to prevent the external air from flowing into the collecting receptacle 10, thereby maintaining the negative pressure condition and avoiding the reduction of attraction force.

[0028] Furthermore, the fastening groove 22 of the guiding cover 20 is only disposed around the outer surface of the collecting receptacle 10 to avoid the forced deformation when the guiding cover is in use, and a gap caused by the forced deformation could be avoided, thereby preventing the reduction of attraction.

[0029] In addition, the present invention adopts a pump motor having a maximum attraction of 550 mmHg to avoid harming the user. So the present invention has no need to adopt an additional pressure regulator valve, and the structure of the present invention is simplified and the risk of breakdown of the pressure regulator valve is avoided.

[0030] In another preferred embodiment, the present invention further has a storage box. The pump motor is securely mounted in the storage box. The collecting receptacle 10 is selectively mounted in the storage box. The present invention is stored in the storage box when not in use to achieve the goal of portability. For use, the user opens the storage box to retrieve the collecting receptacle 10 and make use of the present invention at any place.

[0031] In another preferred embodiment, the slot of the guiding cover could be disposed on the edge of the opening of the collecting receptacle, and the fastening annular flange is mounted on the inner surface of the fastening groove of the guiding cover. In this way, the guiding cover and the collecting receptacle could be embedded with each other.

[0032] Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
