Referring to fig. 12, the supporting frame 43 includes a first beam 431, a second beam 432, a first slider 433 and a slider connecting plate 434.

Specifically, the first beam 431 is fixedly connected to the push rod mounting seat 413, and two ends of the second beam 432 are respectively connected to the two first sliders 433. The first sliding block 433 is connected with the second sliding block 33 in the screw rod device 3 through a sliding block connecting piece 434, and the sliding block connecting piece 434 is fixedly connected with the first sliding block 433 and the second sliding block 33 respectively. The brackets at two sides of the supporting frame 43 are connected with the guide rail column 421 through the fixing block 424.

Referring to fig. 13, the second baffle 44 has a first groove surface 441 and a second groove surface 442.

Specifically, the shape and size of the first groove surface 441 conforms to the shape and size of the calf support plate 400; the shape and size of the second groove surface 442 conforms to the shape and size of the hip plate 401.

Note that the first groove surface 441 is used for accommodating the lower leg support plate 400; the second groove surface 442 is for receiving the hip plate 401.

Specifically, the opposite upper end of the second shutter 44 is further provided with two recesses for receiving the spindles of the first and second electric push rods 411 and 412.

Referring to fig. 14 and 15, the pallet means 4 is located on the opposite right side of the cylinder 10 as shown in fig. 14. The lifting mechanism 41 can adjust the supporting plate 40 to a preset height and angle through the first electric push rod 411 and the second electric push rod 412; the lower leg support plate 400, the hip support plate 404, the waist support plate 402 and the head and neck support plate 404 of the support plate 40 slowly support the person on the wheelchair, and the first electric push rod 411 and the second electric push rod 412 are simultaneously contracted to integrally lift the lifting mechanism 41, so that the support plate 40 is kept in a parallel state. Under the driving of the motor 39, the screw rod 32 rotates to drive the second sliding block 33 to horizontally slide to the left in the screw rod device 3; the second sliding block 33 drives the first sliding block 433 to horizontally slide to the left, the first sliding block 433 drives the supporting frame 43 to move to the left, and the supporting frame 43 is fixedly connected with the guide rail column 421; the guide rail column 421 moves the entire pallet means 4 from the opposite right side of the cylinder 10 to the opposite left side of the cylinder 10 by means of the slider 422 as shown in fig. 15.

Referring to fig. 16, after the pallet means 4 moves from the right side to the left side of the cylinder 10, the lifting mechanism 41 is lowered to the bottom surface of the cylinder 10 by the thrust of the first electric push rod 411 and the second electric push rod 412, and the limit rotating rod 452 of the limit member 45 is rotated by a certain angle by the guide of the guide wheel 170 of the guide means 17, so that the lumbar support plate 402 and the neck support plate 404 are attached to the inclined table 101, and the lumbar support plate 402 and the neck support plate 404 form a sitting posture, so that a person can lean against the inclined table 101, as shown in fig. 16.

The working principle of the intelligent bathtub is as follows:

a caregiver opens the faucet 12 to put water into the tub 10, and adjusts the angle at which the faucet 12 is biased toward the hot water pipe 121 or the cold water pipe 122 to make the temperature of water in the tub 10 reach a preset temperature;

the caregiver adjusts the height and angle of the platform 40 and the lift mechanism 41 to align the platform 40 with the person on the wheelchair bed or dedicated air mattress;

the nursing staff approach the wheelchair bed or the special air cushion to the supporting plate 40, so that the supporting plate 40 is slowly inserted into the gap below the back of the human body, the lifting mechanism is controlled to lift the supporting plate 40, and the person in the supporting plate 40 is lifted;

the nursing staff controls the screw rod device 3 to drive the support frame 43 to move, and the support frame 43 drives the whole supporting plate device 4 to horizontally move to the inner side of the cylinder body 10;

the nursing staff controls the first electric push rod 411 and the second electric push rod 412 to generate thrust, so that the lifting mechanism 41 descends to the bottom surface of the cylinder body 10; under the guiding action of the guiding device 17, the waist and back supporting plate 402 and the head and neck supporting plate 404 form a sitting posture mode, so that a person can lean against the inclined table 101;

the nursing staff controls the water circulation device 18 to start, and the circulating water pump 180, the spray head 16 and the interface 102 provide different bathing modes according to the set bathing mode;

after bathing, the nursing staff controls the first electric push rod 411 and the second electric push rod 412 to simultaneously contract, so that the lifting mechanism 41 is lifted, and the person in the supporting plate 40 is lifted and returned to the wheelchair bed or the special air cushion.

According to the intelligent bathtub provided by the embodiment, by arranging the screw rod device 3, the whole supporting plate device 4 can be driven to move in the horizontal direction through the screw rod 32, the motor 39, the pulley 34 and the second sliding block 33; the whole body of a person can be supported by arranging the lower leg supporting plate 400, the hip supporting plate 401, the waist and back supporting plate 402 and the head and neck supporting plate 403; the support plate 40 is connected with the lifting mechanism 41 through the support plate 40, and the first electric push rod 411 and the second electric push rod 412 in the lifting mechanism 41 can lift the support plate 40, so that people in the support plate 40 can be transferred into the cylinder body 10 for bathing; by arranging the guide device 17, the posture of a person in the supporting plate 40 can be adjusted, the supporting plate is more humanized, and the experience degree of a user can be improved; by providing the water circulation device 18, a plurality of bathing modes can be realized by the water pump 180 and the circular water pipe 181. Compared with the prior art, the intelligent bathtub provided by the invention has the advantages that people are transferred into the bathtub for bathing, the intelligent bathtub is more intelligent and humanized, the operation is convenient, and the burden of nursing personnel can be effectively reduced.

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention.
