Seat type suction suction and defecation device

The present invention is an air suction device that is disposed on a seat and that relies on a negative pressure generated by pumping to assist the seat user in defecation.

In recent years, due to the aging of the population structure, the care and maintenance of the aging population has become an important issue in today's society. Most elderly people suffer from the deterioration of their physical functions due to their age, and they are unfit for the elderly. At the time of evacuation, it is necessary to be supported by the caregiver or to reach the toilet by means of a wheelchair, thus causing the burden on the caregiver. To this end, today's seats have a collection vessel inside and a pad and a perforation on the top wall of the seat. When the user sits on the seat, the toilet can be directly drained and the caregiver only needs to help. The wear and tear of the clothing can reduce the burden on the caregiver.

Although the prior art seat can help the user who is not good at the line, however, the digestive function of most users is not good, which causes the user to have difficulty in the discharge.

In view of the foregoing shortcomings of the prior art, the present invention improves the prior art seat in order to achieve the user's ostracization.

In order to achieve the above object, the technical means adopted by the present invention is to provide a seat type suction attracting and defecation device, comprising: a main body having a loading shell, a mat and an extraction box, and the loading shell is The inner hollow shell structure has a first perforation formed on the loading shell, and the seat cushion is disposed outside the loading The shell is formed with a guiding hole, the guiding hole is aligned with the first perforation of the loading shell, the extraction box is disposed at the inner hollow of the loading shell, the inner space of the extraction box corresponds to the first perforation, and the supporting frame is disposed at the main body a vacuum switch is connected to the main body and is provided with a gas line which is bored and sealed at the side wall surface of the loading casing Space; a pressure regulating valve that is disposed on a side wall surface of the loading casing.

The invention is provided with a vacuum motor for extracting the air inside the loading shell. When the user sits on the seat cushion of the main body, the negative pressure generated by the vacuum can help the user to defecate and pass the excrement through the seat cushion. The guiding hole and the first perforating hole are introduced into the extraction box, and a pressure regulating valve is disposed at the loading shell, and the user adjusts the internal pressure of the loading shell through the pressure regulating valve, thereby achieving the user's optimal use comfort.

Referring to FIG. 1 and FIG. 3, in the practical application, the user sits on the seat cushion 13 of the main body 10. When the user wants to perform the evacuation, the vacuum motor 30 is started through the start switch 22, and the vacuum motor is used. 30, the air pumping in the loading casing 11 is started by the communication effect of the gas line 31. During the pumping process, the air pressure inside the loading casing 11 starts to decrease, and the user located on the seat cushion 13 is generated by pumping. The negative pressure effect is to help the user to perform the evacuation, and the user's excrement will pass through the guiding hole 131 and the first perforation 111 to reach the collecting vessel 14.

Referring to FIG. 4 and FIG. 5, the pressure regulating valve 40 of the present invention is a manual adjusting device, wherein the pressing rod 421 of the knob 42 is screwed into the through hole of the valve 41. In the initial state, the pressure regulating valve The sealing cover 43 of 40 is pressed against the outer side wall surface of the valve 41. This is the optimal sealing state of the pressure regulating valve 40. When the vacuum motor 30 performs the pumping, the pressure in the loading casing 11 starts to drop to form a negative pressure. If the suction generated by the negative pressure is too large, the user can turn the knob 42 to drive the pressure rod 421 to spiral. At the same time, the elastic member 45 is pressed through the valve washer 44, so that the pressing rod 421 is axially displaced at the valve 41, and the sealing cover 43 is separated from the outer wall surface of the valve 41, and the distance from the pressing rod 421 is different. The inflow amount of the outside air is controlled to adjust the internal pressure of the loading casing 11.

The suction function of the vacuum motor 30 in the sealed loading casing 11 can cause a negative pressure inside the loading casing 11 to help the user with poor digestion function to perform the evacuation, and a pressure is placed at the loading casing 11. The pressure regulating valve 40 is used to adjust the pressure inside the loading casing 11, thereby adjusting the vacuum suction force of the present invention to achieve the optimum comfort of the user.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. However, the present invention has been described above by way of preferred embodiments, but is not intended to limit the invention, and is In general, the equivalent embodiments of the above-described technical contents may be modified or modified equivalently, without departing from the technical scope of the present invention, and the above embodiments are implemented according to the technology of the present invention without departing from the technical scope of the present invention.
