Description

Foldable bathtub

Technical Field

The invention relates to a bathtub, in particular to a bathtub which is divided into a front bathtub, a rear bathtub and a back bathtub. The user can sit or lie on the body to clean the body; dirty water under the shower is not on the ground but enters the designated drain hole. The front bathtub and the rear bathtub are provided with lifting guardrails, when a user enters and exits the bathtub, the guardrails are lowered, when the user enters, the guardrails of the bathtub start to lift, and after the user completely enters the bathtub, the guardrails are lifted to the highest. The guardrail not only can give the user a sense of safety, but also can play a role in blocking the bath water sprayed by the shower so that the bath water does not spill on the ground, and ensures that the user and service personnel walk safely on the dry ground.

Background

The body cleaning method comprises three methods of shower, bath and scrubbing, and people with life ability can select according to own hobbies and needs. For patients who basically lose life self-care ability, or patients with severe hypertension and heart diseases, pregnant women near delivery and the like, the bathtub is difficult to enter and exit, and if the patients have sudden illness, the patients are also difficult to pull out of the bathtub, and only people can select to take a shower. The shower has the potential safety hazard of slipping when walking on the ground with water for users or service personnel. However, persons who are fat in height and suffering from heart diseases and hypertension have difficulty in standing or sitting for long time, and particularly persons who are bedridden and fat in height can only choose to wipe.

To solve the problem of cleaning the body of people who need help in life, the bulletin number is CN204207643U, which is named: a bathtub capable of supporting an infant out of the water (hereinafter referred to as an infant bathtub) and an own bulletin number CN106943056B, which are named as a water leakage type bathtub capable of lifting and lowering. The former is to solve the problem of 'baby bath', and if the former is used for solving the problem of adult bath, the disadvantage is that the pad is a whole, and a protective guard with fixed height is arranged around the pad. The infant with ten jin is easy to hold from the pad with the guard rail with fixed height, and the adult with hundreds jin is particularly suffered from hypertension, heart disease, cerebral thrombosis, serious illness or incapacitation of running major operation, half incapacitated old people, pregnant women close to delivery and the like, and the infant is not safe to hold from the bathtub, and the result of the incapacitation is not imaginable once the infant is lost. The drain outlet is arranged at the bottom of the bathtub, and the sleeve pipe cannot be arranged outside the drain outlet, so that the drain plug is pulled up to drain water, dirty water flowing down after the body is cleaned is inevitably prevented from flowing on the ground, and as described above, no matter for adults and service personnel needing to be cared for by the body, the potential safety hazard of slipping exists when the user walks on the ground with water; thirdly, the potential safety hazard of the bathtub is reflected in that the lifting device pulls the crank up and down by hands to push the piston rod to move upwards so as to support the supporting pad out of the water. Because the lifting device of the bathtub is in linear motion and is manually controlled, the supporting pad can slide downwards in a straight line after faults or out of control, so that the lifting device is sometimes inadvisable for infants, like a commander, and can be used for patients suffering from heart diseases, hypertension and cerebral thrombosis, the situation of the patients is aggravated when the patients are frightened and not frightened, and the pregnant women close to delivery are frightened and are extremely likely to be premature. It can be seen that the bathtub with publication number CN204207643U is suitable for infants only and is not suitable for adults with the need for assistance in bathing.

Although the water leakage type bathtub overcomes a plurality of defects of the infant bathtub, the water leakage type bathtub has the following problems in actual use: 1. the bathtub is a fixed whole body, is inconvenient to move, and is not suitable for the bedridden patients with high body weight to take a bath in the bedroom; 2. the water receiving basin at the bottom of the bathtub is connected with the bathtub into a whole, the bottom of the bathtub is formed by a rolling bar, and the bathtub and the water receiving basin are not easy to clean; 3. the bathtub is provided with a rolling bar, the chain is used for driving the chain wheel, and the bathtub cannot be smoothly taken once the chain is separated from the chain wheel in the use process; 4. if the water receiving basin is manufactured to be higher than the basin edge too much, the water receiving basin and the basin are fixed, so that the user can enter and exit the basin (the same problem exists in the infant basin), the water falling down by the shower can not be prevented from splashing on the ground outside the basin when the water receiving basin is manufactured too low, and the user and service personnel walk on the ground with water to have a sliding danger. Although the hollowed-out spliced floor can be anti-slip in the prior art, the hollowed-out spliced floor has to be detached and cleaned at intervals of three and five, otherwise bacteria are bred under the floor, and the floor is spliced and paved one by one after cleaning, so that the hollowed-out spliced floor is troublesome and labor-consuming and time-consuming. Those with difficulty in self-care, especially those who lose their ability to fully self-care, clean their body, place great economic burden and mental stress on family members and become a major problem in the senior citizen's institution.

In the exhibition of Beijing-adapted aged products, a lifting bathtub (shown in figure 18 in detail) is proxied by Japanese, the problem of entering and exiting the bathtub is solved by lifting the bathtub, however, after the bathtub is finished, a user is lifted to leave bath water in the bathtub, residual dirty water on the bathtub is washed off, the body of the user is wiped dry, the bathtub can be taken out, if the body of the user is not wiped dry, the bathtub is very easy to slip when the bathtub is taken out, and the user is suspended on a stool and is necessary to frighten. In addition, the bathtub which is arranged on a stool and is 700 mm high is added with the length of the lower leg which is about 400 mm, namely, the bathtub is suspended at the height of at least 1100 mm, and psychological bearing capacity of heart disease and hypertension patients is considered. That is, the liftable bathtub not only does not fundamentally solve the bathing problem of disabled people with difficulty in self-care in life. How to make people needing help safely, conveniently and comfortably clean the body and simultaneously reduce the physical and psychological burden of nursing staff becomes a worldwide problem.

In summary, a bathtub can be smoothly moved in and out, and can be optionally selected to sit, lean or lie down for bathing; the floor is still dry and clean after the bath process and the bath finish, the safe walking is convenient, the bathtub can be moved at will, in a word, people with difficulty in life self-care, especially those who are bedridden and fat in height, are not only convenient, safe and comfortable in the whole process of bath, but also the bathing tool which is affordable for ordinary families is the problem to be solved urgently.

Disclosure of Invention

The invention solves the problem that people with difficult life self-care can clean the body, in particular to the problem that people with long-term bedridden and high body weight can clean the body. Therefore, the bathtub is divided into a front bathtub and a rear bathtub, and the front bathtub and the rear bathtub can be folded so as to be convenient to move; the front bathtub and the rear bathtub are provided with the lifting guardrails, when a user goes up and down the bathtub, the guardrails and the edges of the bathtub form a plane, even if the bathtub is inflated, the guardrails are soft and do not prevent the user from going in and out of the bathtub, the guardrails lift up to the user after entering the bathtub, the other function of the guardrails is that the water sprayed by the shower is not splashed on the ground, and the user and the service personnel can walk on the dry ground with confidence after the bathing is finished; in order to ensure absolute safety in the use process, the bottoms of the front bathtub and the rear bathtub are provided with safety brackets; a water receiving tank is arranged at the joint of the front bathtub safety support and the rear bathtub safety support, the water receiving tank is provided with a water drain hole, and a sleeve can be arranged outside the water drain hole; a stabilizing frame is arranged under the rear bathtub safety support, a movable rod 38 with a pulley is arranged at the rear part of the rear bathtub safety support, the movable rod 38 slides backwards or forwards along with the lifting of the rear part of the rear bathtub, and the movable range of the movable rod 38 is within 3 e; the rear bathtub can be lifted up and down integrally, and the rear portion of the rear bathtub can be lifted up and down, so that the rear bathtub can be lifted up to a certain height to stop lifting due to the fact that the movable range of the movable rod of the rear bathtub is within 3e and the travel switch is arranged, and the lifting is quite safe. In order to achieve the design purpose, the invention is provided with 6 bathtub supporting frames and 2 lifting devices; the bottoms of the front bathtub and the rear bathtub are arc-shaped, and the bottoms are provided with a plurality of elastic protruding edges, and each protruding edge is provided with a plurality of small cylinders with the height of 1-2 mm and elasticity. When the front bathtub is arranged on the first bathtub supporting frame, the second bathtub supporting frame, the third bathtub supporting frame and the fourth bathtub supporting frame, the front part of the front bathtub is slightly higher than the rear part of the front bathtub; the second support frame of the bathtub and the third support frame of the bathtub can be folded.

Compared with the water leakage type bathtub, whether the front bathtub or the rear bathtub is connected with the water receiving bathtub into a whole, and the water leakage type bathtub is large and heavy in size and inconvenient to move, the water leakage type bathtub has the advantages that the front bathtub is divided into the front bathtub and the rear bathtub, when the front bathtub is not used or moved, the front bathtub is lifted to be combined with the rear bathtub, and the two feet of the front bathtub are pulled down to be balanced with the bathtub, so that the whole bathtub is reduced by nearly half (see figure 20 for details, namely a sample manufactured by the design). The front part of the front bathtub is slightly higher than the rear part, the rear part of the rear bathtub can be lifted, the connecting part of the front bathtub support and the rear bathtub support is provided with a water receiving groove, and the dirty water after washing flows into the water receiving groove from the grooves at two sides of the protruding edges of the bathtub (see figure 1 for details and the figure 19 of the manufactured sample in the design), so that the structure is simple, the cleaning is convenient, and the weight of the bathtub is greatly reduced. The problem that the bedroom is cleaned by the person who is not bedridden and is high is solved by only prolonging the hot water pipe and the drain pipe.

Compared with the name of the water leakage type bathtub, the water leakage type bathtub has the advantages that although the water leakage type bathtub is provided with the guardrail, the guardrail of the water leakage type bathtub is formed by heightening the edge of the water receiving bathtub, and the height of the guardrail is fixed. If the guardrail is too high, as described above, the guardrail will appear and be advertised in CN204207643U, named: the same problem of a bathtub capable of supporting an infant out of the water is that it is difficult for an adult who needs assistance in bathing to go into and out of the bathtub; too low to ensure that the water sprayed down during showering does not splash to the ground. The guardrail provided by the invention is inflatable, lifting and elastic, and is inflated when in use, the bathtub edge is lifted, and when a user goes up and down the bathtub, the gas is discharged, and after the guardrail is deflated, the bathtub edge is a plane, so that the user can conveniently go in and out of the bathtub. The guardrail does not obstruct the user from going up and down the bathtub, but also gives the user a sense of safety in the process of cleaning the body, particularly in the process of cleaning the body, and plays a role of blocking the water sprayed by the shower from being sprayed out of the bathtub (see figure 19 in detail), so that the drying of the ground is ensured, and a safe walking environment is provided for the user and service personnel.

Compared with the water leakage type bathtub which is realized by transmitting power through 4 chains, the invention has the advantages that the integral lifting of the bathtub is realized by only two lifting devices, and the structure is simple; compared with the lifting of the rear bathtub of the water leakage type bathtub, the lifting device is firstly lifted to a certain extent, then the steel wire rope is used for pulling up, once one side of the steel wire rope is loosened, the bathtub is possibly inclined, a user sits in the slightly inclined bathtub, the body is very uncomfortable to clean, and the inclination seriously scars the user.

Compared with the design that the feet of the baby bathtub are slightly higher than the buttocks, the head is higher than the feet, the bathtub is an integral body, the design aims to enable the head of the baby to be exposed out of the water surface in the bathing process so as to avoid drowning, firstly, the design aims to enable the rear part of the rear bathtub to be slowly lifted when the buttocks of a user slide to the front bathtub and then not slide down due to the fact that the feet are slightly higher than the buttocks. Because the user leans on the back bathtub, when the buttocks slowly slide to the back bathtub from the front bathtub with inclination, on one hand, the speed is low, and on the other hand, the fall of the back bathtub and the front bathtub is not more than 120 mm (when the patient with heart disease and hypertension moves to the stretcher from the bed to the fall of about 300 mm in emergency), the buttocks muscles are more abundant than other parts, the discomfort can not be generated, and the use is very safe. Secondly, the front bathtub and the rear bathtub have inclination, so that the dirty water washed down can smoothly flow into the water receiving groove at the joint position under the safe support of the front bathtub and the rear bathtub. And thirdly, compared with the baby bathtub, the transverse protruding edges on the baby bathtub supporting pad mainly play a role in preventing the baby from sliding downwards, and the longitudinal protruding edges at the bottom of the bathtub are beneficial to drainage. The back bathtub is characterized in that the back bathtub is provided with a convex edge, the convex edge is provided with a convex edge, and the convex edge is provided with a convex edge. The design purposes are different, and the generated technical effects are different.

The dirty water washed by the water leakage type bathtub is leaked into the water receiving basin below the bathtub through the gap between the rolling strips, then flows into the designated drainage channel through the drainage pipe, and the rolling strips are brushed one by one and the power supply is turned on during cleaning, so that the periphery of the rolling strips is cleaned, and the water receiving basin is cleaned and also passes through the rolling strips, so that the washing is quite troublesome and is compared. The invention relates to a bathtub, which is characterized in that the height of the two ends of the bathtub is higher and the middle of the bathtub is lower, dirty water after washing flows into a water receiving groove from grooves on two sides of a protruding edge at the bottom of the bathtub, then flows into a designated water discharging pipe through a water discharging hole on the water receiving groove and a pipe outside the water discharging hole, and when the bathtub is cleaned, the bottom of the bathtub and the water receiving groove are brushed by only taking a brush, the water is washed by one time, so that the bathtub is quite convenient, and the manufacturing cost is far lower than that of a water leakage type bathtub.

Compared with the water receiving basin at the bottom of the baby bathtub, the invention designs a small and exquisite water receiving tank only at the joint of the front bathtub safety support and the rear bathtub safety support, and the cost of the installation and the raw materials is greatly lower than that of the front bathtub safety support and the rear bathtub safety support, and the invention is more important to facilitate water drainage and cleaning. The water leakage type bathtub is characterized in that the water leakage type bathtub is provided with a water drain hole, and the water drain hole is provided with a water drain pipe. The design has only one drainage hole, the outer pipe and the drainage hole are spliced by utilizing the characteristics of thermal expansion and cold contraction of plastics, and the sealing degree is far higher than that of a water leakage type bathtub, and one pipe sleeve is sleeved on two semicircular holes. Compared with the inconvenience of water walking on the whole ground caused by the pulling of the gate of the baby bathtub, the invention ensures that users and service staff walk safely on the dry ground by flowing into the appointed drainage channel through the pipe outside the drainage hole on the water receiving tank.

Compared with the straight line lifting of the baby bathtub and the manual control, once the straight line sliding down due to faults is happened, the invention takes the screw rod and the threaded sleeve with the internal thread as the lifting device, even if power failure happens, the screw rod and the threaded engagement in the lifting device stop, and the user is not frightened, so the invention is more suitable for adults with difficult life and self-care, especially people suffering from heart disease, hypertension, pregnant women and the like.

The upper end face of the supporting pad of the baby bathtub is provided with a transverse protruding edge parallel to the horizontal plane, the upper end face of the transverse protruding edge is arc-shaped, the transverse protruding edge has better anti-sliding effect than the straight protruding edge, and the bottom of the bathtub is provided with a longitudinal protruding edge, and the upper end face of the longitudinal protruding edge is arc-shaped, but the bottom of the bathtub is provided with a plurality of small cylinders with the height of 1-2 mm, which are elastic, the small cylinders with the elasticity not only play a massage role, but also have elasticity, so that the small cylinders are dispersed on one hand, the user is stressed differently against the upper side, the downward sliding of the user is blocked, the downward sliding speed is reduced, and the baby bathtub is safer.

Compared with the electric lifting bathtub which is shown in a Japanese house at a Beijing International aged industry exposition in 2018 in FIG. 18, the bathtub is convenient for users to go in and out and is suspended and sitting on a one-meter-multiple chair to go in and out, and the mental pressure of people with hypertension, heart disease and inconvenient actions is greatly reduced when the users clean the body each time; compared with the prior public bathhouse of the senior citizen which sits on a stool with fixed height for bathing, the invention is safe and comfortable to use, and can randomly select the bathing modes such as sitting, leaning, lying and the like.

In summary, the present invention is superior to prior art body cleaning baths in both practicality and manufacturing costs.

However, these embodiments are illustrative, and are not intended to limit the present invention. The order of the combination of the components in the embodiments of the present invention described below is not limited to a conflict, and may be changed without any conflict.

The first step: firstly, a front bathtub safety support 24 which is formed by carrying out electric welding on a front bathtub formed by PP injection molding and stainless steel bars, namely 23a to 23n in figure 3 are aligned with 22a to 22n corresponding to figure 2 and then fixed by screws; the rear bathtub safety support 34, namely 33a to 33n of fig. 5, is fixed by screws after aligning with the corresponding 30a to 30n of fig. 4, and is manufactured by electric welding of a rear bathtub and a stainless steel bar which are formed by PP injection molding. 22a to 22n and 30a to 30n are through screw holes. The roller shafts 38 with pulleys at both ends are mounted in 3e of fig. 4 and fixed at 3f and 3g with screws, respectively. The effect of the two stainless steel bars 2a and 3b in fig. 2 and 4 is further stiffening. And a second step of: two 31b of the water receiving groove 29 of fig. 11 are aligned with two 31a of the rear tub safety support of fig. 4 and are fixed by screws. The material of the water receiving tank can be waste recycled plastics; and a third step of: motor a is positioned at the rear tub support 55a of fig. 12-1 and motor B is positioned at 55B with the power of motor B being about 20W greater than the power of motor a. When the rear bathtub is lifted integrally, the front motor and the rear motor work simultaneously, and when the rear bathtub is lifted, the motor A is at rest and the motor B works. The lifting device can also be a triangular lifting rear bathtub, namely, the motor A is arranged at the position of the 12-2 rear bathtub supporting frame 55a, the motors B and C are respectively arranged at the positions of 55B and 55C, and the power of the three motors A, B and C is the same. When the rear bathtub is lifted, the three motors work together, and when the rear portion of the rear bathtub is lifted and lowered, the motor A is at rest, and the motors B and C work simultaneously. The rear bathtub supporting frame is formed by stainless steel electric welding in a prefabricating mode, and the rear bathtub supporting frame 51, the rear bathtub supporting frame 51a, the rear bathtub supporting frame 54 and the rear bathtub supporting frame 54a can be made of a whole stainless steel pipe or can be separated and sleeved in a rotary mode in a threaded mode. Fourth step: the screw of fig. 14 is placed on the motor a head, the pins are passed through 55i to secure the screw on the motor head, and then the elevator of fig. 15 is rotated over the screw of fig. 14 to abut the bottom of the screw. The screw of fig. 16 is placed on the motor B head, the pins are passed through 55j to secure the screw on the motor head, and then the elevator of fig. 17 is rotated over the screw of fig. 16 to abut the bottom of the screw. The steel materials of the screw and the lifting device are commonly used; fifth, the stabilizer of FIG. 9 is placed in the front lifter of the rear tub, and screws are passed through 55g and 34c to fix the stabilizer to the front lifter of the rear tub. The stabilizer of figure 10 is placed in the rear lift of the rear tub and screws are passed through 55h and 38c to secure the stabilizer to the rear lift of the rear tub. If the rear part of the rear bathtub is lifted in a triangular lifting mode, the other stabilizer in the figure 10 is placed into the rear lifting device of the rear bathtub above the motor C, and screws pass through 55h and 38C to fix the stabilizer on the rear lifting device of the rear bathtub. The two stabilizing frames are made of stainless steel, and are prefabricated in advance (namely, the other ends of the stabilizing frames 34a and 34b are stacked together and put into a groove of the lower part 34d and then are plugged into a pin for stamping, the other ends of the stabilizing frames 38a and 38b are stacked together and put into a groove of the lower part 38d and then are plugged into a pin for stamping, the bottoms of the stabilizing frames 34a and 34b,38a and 38b are stepped, and two sides of the stabilizing frames are on the same plane after the stabilizing frames are stacked together). Sixth, the inflator 59 is positioned before 55a of fig. 12 so as to be as close to the front tub as possible; seventh step: a travel switch 57 is arranged beside the motor B, namely 55B; eighth step: the fixed fig. 5 and 4 are put on fig. 9 and 10, and the two screw holes 3a of fig. 4 are aligned with 34a and 34b, respectively, and the screw fixed rear rolling shaft 38 is just embedded in 38a and 38b of fig. 10. Ninth step: two hinges are used to connect two of the front tub safety brackets 28a of figure 2 with two corresponding brackets 21b of the rear tub support of figure 12. Tenth step: two hinges are used to connect the two feet 51a of the front tub of fig. 13 to the front tub safety bracket 28 of fig. 2, respectively. The two feet of the front bathtub in figure 13 are made of hollow stainless steel tubes, and can also be hollow tubes formed by injection molding of PP. Eleventh step: the fastening holes 39a to 39n of one inflatable guardrail in fig. 6 are respectively aligned with the corresponding fastening buttons 26a to 26n in the groove 21 in fig. 3 to be pressed, so that the inflatable guardrail is embedded into the groove of the front bathtub 21. The buckling holes 39a to 39n on the other inflatable guardrail in fig. 6 are respectively aligned with the corresponding buckling buttons 36a to 36n in the groove 31 in fig. 5 to be pressed, so that the inflatable guardrail is embedded into the groove of the rear bathtub 31. Twelfth step: the air inlet mouth C on the front bathtub guardrail is connected with the air outlet E of the inflator pump in the figure 12 by a pipe, and the air inlet mouth C on the rear bathtub guardrail is connected with the air outlet F of the inflator pump in the figure 12 by a pipe. Because the two sides of the guardrail are tooth-shaped, the guardrail can be automatically folded after being deflated, and the guardrail can automatically enter the groove 21 of the semicircular bathtub side in fig. 3 and the groove 31 of the semicircular bathtub side in fig. 5 after being folded. The guardrail material on the front bathtub and the rear bathtub is PP.

The working process comprises the following steps: pressing a button a (a, b, c, d, e on 60 is not marked) on the bathtub in fig. 1 to charge the air pump, then pressing a whole lifting button b of the rear bathtub on 60 in fig. 1 after the user arrives beside the bathtub, and releasing the button b when the whole rear bathtub rises to the height required by the user, so that the user can rotate the feet of the user towards the front bathtub after sitting on the bathtub, and the head of the user faces towards the rear bathtub. After sitting, the guardrail inflation buttons d and e of the front bathtub and the rear bathtub are pressed while the lifting button c of the rear portion of the upper bathtub and the rear bathtub are pressed 60, and as the rear portion of the rear bathtub is gradually lifted, the buttocks of a user slowly slide forward until the buttocks of the user completely slide down the front bathtub, and then the angle of the rear bathtub is adjusted by pressing c according to the needs of the user. The body is cleaned, the air is filled or not without a pipe, and the air pump automatically closes the inflatable guardrail after the inflatable guardrail is filled with air. When the body cleaning is finished, the air release Niu Sai H of the inflatable guardrail in fig. 6 is pulled up, the integral lifting button b of the rear bathtub is pressed, and the body is wiped for a user when the rear bathtub descends. When the body of the user is wiped off, the air in the guardrail does not influence the user to sit on the guardrail and fall down the bathtub even if the body of the user is not completely put off, because the guardrail is soft, the service personnel reminds the user of falling down the bathtub, so that the user is mental to prepare, the user gradually slides to the rear bathtub to slide down the rear bathtub along with the whole falling of the rear bathtub, and after the rear bathtub is completely slid down, the rear bathtub such as a rear falling button c is pressed, and the rear bathtub integral lifting button b is pressed. When the rear bathtub falls to a position suitable for the user to fall to the ground and the button b is released, the air pump air release button is pressed (if the bathtub is a geracomium, one person is used for washing the ground and then the other person is used for washing the ground, the air pump is not required to be released, and the air pump is required to be inflated, in addition, the front bathtub air inflation guardrail is not deflated, namely the air inflation Niu Sai is not pulled out, and finally the user is helped to fall to the ground. After the bath is completed, the brush is held and flushed once, and the washing is fast. When the inflatable guardrail is not used, the front bathtub is folded on the rear bathtub (see figure 20 in detail), and two feet of the front bathtub are folded to be balanced with the bathtub, so that the whole bathtub can be lifted up and put in a proper place.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations of the present invention will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
