Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an excrement expelling auxiliary device, and more particularly to an non-invasive excrement expelling auxiliary device using vacuum suction to help a user suffering from constipation expel the excrement from the large intestine.

2. Description of Related Art

In general, fruit and vegetables are good food to help digestion. However, constipation often becomes the major problem for so-called white-collar-workers in that the pressure from the work as well as the family causes irregular eating habits. In addition, gastrointestinal illness is another cause of constipation. People who suffer from constipation often receive a prescription for a laxative etc from the medical doctor. Especially, when the constipation situation is serious, doctors will have to use invasive tool to dig out the excrement in the small or large intestine. Using laxative or enema somehow may have its effect, but the chemical reaction of the medicine to the human body may also cause discomfort to the user. Still, using invasive tool to force out the excrement may damage the anus, the small intestine and/or the large intestine and sometimes may also cause bacterial infection.

To overcome the shortcomings, the present invention tends to provide an improved non-invasive excrement expelling auxiliary device to mitigate the aforementioned problems.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide an non-invasive excrement expelling auxiliary device using vacuum suction to allow the excrement in the intestines to be sucked out.

In one aspect of the present invention, the non-invasive excrement expelling auxiliary device of the present invention has a cover removably mounted on top of the toilet bowl and having an opening defined through the cover and a wall formed on a portion of a periphery defining the opening, a vacuum suction device connected to the toilet via a hose such that when the vacuum suction device is activated, the air inside the toilet will be sucked away and the internal pressure inside the toilet is dropped, which sucks the excrement in the small intestine and large intestine.

In yet another aspect of the present invention, a pressure switch is mounted between the toilet bowl and the cover to sense pressure on top of the cover such that when there is a load on top of the cover, the pressure switch closes communication between the interior of the toilet and the drainage pipe via an electromagnetic valve in the drainage pipe to allow the internal pressure in the toilet to drop dramatically so as to help expel the excrement.

Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1, 2, 3 and 4, it is noted that the non-invasive excrement expelling auxiliary device in accordance with the present invention includes a toilet bowl (10), a cover (20), a vacuum suction device (30), a drainage pipe (40) and a water tank (50).

The toilet bowl is in communication with the drainage pipe (40) and the water tank (50). A water pipe (51) connects the water tank (50) to the toilet bowl (10). The cover (20) is pivotally mounted on top of the toilet bowl (10) to selectively close a top opening (not shown) of the toilet bowl (10) and has an opening (21) defined through the cover (20) to communicate with an interior of the toilet bowl (10) and a wall (22) formed on a periphery defining the opening (21). The vacuum suction device (30) is in communication with the interior of the toilet bowl (10) via a pipe (31). An electrical wire (301) is extended out from the vacuum suction device (30) and a controller (32) is provided at a free end of the electrical wire (301) so that the user is able to hold the controller (32) to control activation of the vacuum suction device (30). Furthermore, a cushion (23) is sandwiched between the toilet bowl (10) and the cover (20) and has a slit (231) defined through the cushion (23) to receive therein a pressure switch (11) which is in connection with a electromagnetic valve (41) received in the drainage pipe (40). Therefore, whenever there is a predetermined load on top of the cover (20), the pressure switch (11) sends a signal to the electromagnetic valve (41) to activate the electromagnetic valve (41) so as to block the drainage pipe (40).

With reference to FIG. 5, when a user is using the non-invasive excrement expelling auxiliary device of the present invention, the user is sitting on top of the cover (20) with his anus in alignment with the opening (21) and user's buttocks abut the wall (22) to fully block the opening (21). Thereafter, the user activates the vacuum suction device (30) with the controller (32). Because the electromagnetic valve (41) blocks the drainage pipe (40) due to the activation of the pressure switch (11) in the cushion (23), the activation of the vacuum suction device (30) is able to reduce the air pressure inside the toilet bowl (10), which forms a suction effect to help expel the excrement in the large intestine. This kind of excrement expelling tool does not do damage to the user's internal organs nor cause bacteria infection, and thus is a clean and useful excrement expelling auxiliary device.

With reference to FIG. 6, a different embodiment of the present invention is shown. The non-invasive excrement expelling auxiliary device in this embodiment has a toilet seat (60), a cover (70) and a vacuum suction device (80).

The cover (70) is on top of the toilet seat (60) and has an opening (71) defined through the cover (70) and a circular wall (72) surrounding the opening (71). The vacuum suction device (80) is in communication with the toilet seat (60) via a pipe (81) which is in connection with a toilet pipe (61) via a joint (83). An electrical wire (801) is extended out of the vacuum suction device (80) and a controller (82) is provided at a free end of the electrical wire (801). It is noted that in this embodiment, there is no water tank and water pipe so that the user is able to carry the non-invasive excrement expelling auxiliary device of this embodiment to wherever required.

It is to be understood, however, that 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 function of the invention, the disclosure is illustrative only, and changes may be made in detail, 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.
