Description

Water barrier device and corresponding nursing machine host

[technical field]

The utility model relates to medical treatment and nursing equipment technology fields, the in particular to water barrier device of cleaning device.

[background technique]

It is right because the bed patient that stool, urine cannot take care of oneself caused by cardio-cerebrovascular diseases is increasing year by year in society Family, society bring very big pressure, since the defecation of patient cannot take care of oneself, need the assistance of entourage, and patient arranges Just the uncertainty of time increases the workload of entourage, and physiology to patient, particularly mentally causes very big Pain and burden.Therefore, medical institutions and patient' s family are often that patient is equipped with stool and urine cleaning device.

The cleaning device of the prior art mainly includes wearable toilet waste collector, host, is usually connected between toilet waste collector and host It is connected with water supply pipe, soil pick-up pipeline etc., toilet waste collector is equipped with urinal, and host, which is typically provided with, provides the negative pressure of suction excretion dirt power Source, the sewage tub assembly for accommodating dirt, negative pressure source include air inlet entrance, wind exhausting outlet, motor and are driven by motor and rotate Impeller, motor driven impeller rotate and generate suction force, aspirate the process of slop substantially are as follows: defecation of human body is in toilet waste collector In urinal, the spray head of toilet waste collector rinses human body and excreta, negative pressure source are aspirated, the excreta, sewage in urinal along with The air-flow of suction is inhaled into sewage tub assembly via soil pick-up pipeline, and the air-flow of suction is further by sewage tub assembly via slop pail Pipeline between component and water barrier device flows into the inner cavity of water barrier device, further by water barrier device via negative pressure source and water proof Pipeline between device flows into negative pressure source, then is discharged from negative pressure source wind exhausting outlet.

Since the air-flow above-mentioned for flowing through water barrier device inevitably has more steam and a small amount of foreign matter is (different Object is derived from slop, during entire excreta is sucked along with air-flow, be circulated to air-flow that water barrier device obtains, Inevitably can slightly mix the minimal amount of foreign matter isolated from excreta in steam, also cause air-flow be it is smelly, in order to remove It is smelly, the cleaning device of the prior art generally all can negative pressure source wind exhausting outlet be arranged deodorization unit, such as anion deodorization unit or The existing common deodorization mechanism such as catalyst deodorization unit), cause gradually accumulate liquid (water and foreign matter) in water barrier device, with Water barrier device accumulation water water level increase, may occur when negative pressure source normally aspirates water barrier device accumulation water it is straight It connects and is pumped into negative pressure source and is discharged, it is impaired to will lead to negative pressure source water inlet, and host is caused to be discharged outward and bungle ambient enviroment.

For this purpose, CN203829212 discloses a kind of water barrier device of prior art: when the water level for the water accumulated in water barrier device Certain predetermined height is reached, floating ball set by water barrier device floats and, when negative pressure source work floating ball close with outgoing gas connection tube distance It can be adsorbed and block the outgoing gas connection tube of water barrier device, be accumulated so that negative pressure source be avoided to draw in water barrier device Water, air inlet tube is corresponding opposite up and down with water storage cup and is located above storage chamber, and the foreign matter accumulated in water storage cup is easy accumulation water And foreign matter, the foreign matter accumulated in water storage cup are easy the water along with accumulation without the diffusion of blocking, so that foreign matter is easy diffusion To the side where floating ball, lead to that more foreign matter can be adhered on floating ball, meeting large effect floating ball normally floats and blocks out Gas adapter tube.
