Vortex flow cleaning system suitable for defecation nursing device

Abstract

The application discloses a vortex flow cleaning system suitable for a defecation nursing device, comprising a urine and feces collector, a water supply system and a negative-pressure sewage pumping system, wherein one end of the urine and feces collector is provided with an opening and the other end is provided with an outlet, a urine and feces collecting cavity is arranged between the opening and the outlet; the urine and feces collecting cavity gradually becomes smaller along the direction from the opening to the outlet, and the cavity wall of the urine and feces collecting cavity is a smooth hook face; the urine and feces collector is also provided with an air inlet hole and a water inlet hole which are both communicated with the urine and feces collecting cavity, the air inlet hole and the water inlet hole are arranged along a tangential direction of the cavity wall of the urine and feces collecting cavity; the water supply system is connected with the water inlet hole; the negative-pressure sewage pumping system is connected with the outlet. According to the vortex flow cleaning system suitable for the defecation nursing device, the air inlet hole and the water inlet hole are arranged in the urine and feces collector along the tangential direction of the urine and feces collecting cavity, so that the water and air entering from the tangential direction can form a spiral vortex flow along the inner wall of the urine and feces collecting cavity, the cleaning range of the vortex flow is wide and the effect is good, the urine and feces collecting cavity is omnidirectionally cleaned while the urine and feces are flushed away; the water is saved, and no high pressure water pump is needed to drive a water source to enter, so that the cost is reduced.

Description

technical field [0001] The present application relates to a human body care device, in particular to a vortex water cleaning system suitable for a toilet care device. Background technique [0002] The defecation care device is mainly used to help people who are unable to take care of themselves to clean the defecation. When in use, the defecation care device is directly placed at the defecation place of the human body, collects and cleans the defecation of the human body, and cleans the buttocks of the human body. [0003] Excretion is generally divided into two stages when the existing defecation care device processes the excrement. The first stage uses scattered water flow to clean the defecation chamber along the bottom of the defecation chamber. The disadvantage is that, first of all, the water supply system is complicated for segmental cleaning. Secondly, due to space constraints, the diffuser nozzle cannot be cleaned and cannot cover the entire cavity, so there will b...

AI Technical Summary

Problems solved by technology

The disadvantage is that the individual differences of the human body are large, and the nozzle is difficult to align accurately, so the cleaning effect is poor. Because the water flow is sprayed from the inside out, the tight seal between the human body and the seat will cause water leakage

Another existing vortex water flow cleaning structure can clean all excretory areas of the human body, but because the way of generating vortex water flow cannot produce high-speed vortex water flow, the cleaning effect is limited, and the direction of the hole is also affected by the porous air jet structure. The layout requirements are high, otherwise the vortex effect will be affected, the stability is poor, and it is difficult to adapt to the special-shaped surface and the flat base of the toilet cavity

[0005] In the prior art, there is also the method of vortex water flow for processing, such as the principle of vortex water flow cleaning described in patent WO2014183269A1, its function is also only used for cleaning human skin, and does not perform excrement and stool collection cavity on the water flow Reuse, water saving effect is not obvious

The most important thing is that the speed of the vortex airflow generated by the method of porous injection gas is not high, and the vortex airflow is only generated on one plane, and the airflow in the entire cavity cannot be rotated, so the power to drive the water flow is limited, and the cleaning effect is not good. optimal
