Description

Self-adaptive toilet auxiliary device and self-adjusting method

Technical Field

The invention relates to the technical field of bathroom equipment, in particular to a self-adaptive toilet auxiliary device and a self-adjusting method.

Background

The human being through long-term evolution, from the faecal angle, the physique has adapted to the state of squatting pan completely, and the thigh is 35 degrees angles with the trunk during squatting pan, and pubic rectum muscle relaxes completely, can let the large intestine clear up the excrement rapidly and completely like this, shortens the defecation time, reduces the emergence such as constipation, haemorrhoids. However, legs and feet are prone to numbness when the squatting pan is in a long-term posture, blood cannot reach the brain in time when the squatting pan is in an emergency, postural hypotension is formed, transient cerebral blood supply insufficiency occurs, dizziness and blackness are easily caused, and the people can fall down in a serious condition.

The sitting type closestool can support the buttocks and thighs of a user due to the sitting surface, and is very comfortable, but when the sitting type closestool is used for defecating, muscles around the anus can pull the rectum, part of puborectalis muscles are loosened, and the colon is twisted to block the outflow of excrement, so that the defecating needs to be exerted harder, and anal fissure, constipation and the like are easily caused.

4 month 2 days 4 of 2014, and authorized bulletin number CN203514466U, discloses an intelligence bath toilet, and it can adjust the height of people's foot when like the lavatory at any time, makes the angle between upper part of the body and the thigh diminish, accords with the rectum structure, makes puborectalis muscle obtain thoroughly relaxing, ensures people's health.

An authorized bulletin date of 2019, 4, 9 and an authorized bulletin number CN208709731U discloses an adjustable closestool cushion footrest, which comprises an arc-shaped base, an arc-shaped stool surface and a support column with adjustable height, wherein the arc-shaped stool surface is supported on the arc-shaped base through the support column with adjustable height. The utility model discloses can adjust the height of adaptation according to different crowds' demand, let people can simulate the pit posture when sitting the closestool like the lavatory, reach comfortable defecation angle, make pubis rectum muscle relax completely, let the large intestine empty rapidly, make like the lavatory more freely.

Application publication No. CN109674383A, application publication No. 4/26/2019, discloses an electric auxiliary toilet stool bracket, which comprises a lifting device and a foot supporting device, wherein the foot supporting device is arranged on the lifting device, and the lifting device comprises a first lifting device, a second lifting device and a seat plate. Thereby elevating gear's pneumatic rod can be with the bedplate jack-up lift the old man and stand, and foot strutting arrangement can raise its shank according to the old man of different heights when like the lavatory, makes thigh and drainage be 35 degrees angles, and pubic rectal muscle relaxs the shit and can discharge smoothly, shortens the defecation time, reduces the emergence such as constipation, haemorrhoids.

Application publication date

2019, 5 and 3, and application publication number CN109700368A, which discloses a toilet bowl auxiliary device, comprising an anti-skid rubber pad, a seat body, a foot placing mechanism, a back cushion, a back adjusting mechanism, a back body and a prompt pattern, wherein the seat body and the foot placing mechanism are arranged, so that a user places two feet on the foot placing mechanism when going to a toilet, and the height of the seat body is set to be 30-40cm, so that the legs and the body of the user form an angle of 35 degrees, the phenomenon that the two feet are numbed due to the fact that the blood circulation is not smooth under the compression of the root of the thigh can be effectively prevented, the pubic rectal muscle is relaxed, the discharge of excrement in intestinal tracts is facilitated, the urine in the bladder of a female can be emptied, and various diseases can be prevented.

However, the above patents have several disadvantages, such as: the intelligence bath toilet of mandate notice number CN203514466U, even if through the height of atmospheric control pole adjustment foot when lavatory, nevertheless because the people is unknown at upper part of the body gesture angle when toilet seat, can't guarantee that thigh and trunk are 35 degrees angles, can't guarantee that the puborectalis is in the complete state of relaxing.

The adjustable toilet pad footrest of authorized bulletin number CN208709731U, even if through the height of adjustable high pillar adjustment foot when like the lavatory, nevertheless because the people is unknown at upper part of the body gesture angle when the toilet seat, can't guarantee that thigh and trunk are 35 degrees angles, can't guarantee that puborectalis is in the state of relaxing completely. Meanwhile, due to manual adjustment, secondary adjustment is inconvenient to carry out even if the toilet is found out to be improper, and the limitation is large when the toilet is used.

The electronic supplementary closestool support in patent CN109674383A, although the accessible is the control switch adjustment bedplate on hand and the running-board height, because the people is unknown at upper part of the body gesture angle when the toilet seat, can't guarantee that thigh and trunk are 35 degrees angles, can't guarantee that the puborectalis is in the complete state of relaxing.
