Description

Technical Field

[0001] The present invention belongs to the field of bathing, and particularly relates to a double-gear rolling, rubbing, massaging and liquid squeezing device. Background Art

[0002] As China gradually enters an aging society, the number of elderly people with limited mobility is increasing day by day. At the same time, the gradual improvement of people's living standards makes more families hope that the elderly with limited mobility and disability can enjoy their old age at home. However, problems such as the lack of family members' awareness of nursing, the limitations of the cost and size of large and advanced equipment, and the single function of medium and small-sized equipment have made it extremely difficult for ordinary families to provide cleaning and nursing care for the disabled elderly, especially the daily bathing work. Therefore, it is very necessary to design a family-use elderly bathing assistance device with comprehensive functions and appropriate size.

[0003] In view of this, our team has designed an automated elderly bathing assistant. When in use, as long as the user sits on it, the machine will automatically wash the user's head and upper and lower bodies, automatically clean, massage and rub the user's head, automatically scrub the upper and lower bodies of the user, apply body wash, wipe the body and rinse, and after washing, it will also apply body lotion, massage and dry. It has powerful functions, is safe and comfortable, and is easy to operate. It can not only automatically bathe the whole body of the elderly with limited mobility, but also is a blessing for the disabled and lazy people, and can be widely used in places such as families, hotels, guesthouses and bathing centers.

[0004] The automated elderly bathing assistant mainly consists of a head cleaning and massaging device 1, an upper and lower body rotary cleaning, scrubbing, massaging and liquid spraying device 2, a one-source multi-motion deformable seat 3 and a control system. The head cleaning and massaging device 1 can complete the functions of cleaning, rubbing and massaging the head. The upper and lower body rotary cleaning, scrubbing, massaging and liquid spraying device 2 can perform functions such as cleaning, spraying body wash, rubbing and massaging the upper and lower bodies during the spiral rotation process. The one-source multi-motion deformable seat 3 can not only make people in the standing, sitting and reclining states to comfortably complete the bathing function, but also send the elderly into and out of the bathing room. The whole set of devices is automatically controlled and completed by a PLC control system.

[0005] In the early stage, our team's invention patent "an upper and lower body rotary cleaning, scrubbing, massaging and liquid spraying device" has a main body mainly composed of a rotary device 6, a screw-nut moving device 7, a rubbing and massaging paste-applying device and a liquid spraying system 9. However, the rubbing and massaging paste-applying device can only be used for bathing with barreled liquids (barreled body wash, barreled shampoo, barreled skin care liquid), and it cannot complete the process of spraying and applying body wash and other liquid spraying for the currently common bagged bathing products (bagged body wash, bagged shampoo, bagged skin care liquid), so the bathing cannot be smoothly completed. To solve this problem, the present invention reasonably modifies the rubbing and massaging paste-applying device of the previous invention patent "an upper and lower body rotary cleaning, scrubbing, massaging and liquid spraying device", and proposes a double-gear rolling, rubbing, massaging and liquid squeezing device 8.

[0006] The features of the previous patent achievement, "An upper and lower body rotating cleaning, scrubbing, massaging and liquid spraying device", are as follows: The moving motor 16 and the U-shaped profile 17 of the screw-nut moving device 7 are both fixed on the rotating rod 46 of the rotating device 6. A number of spray heads 18 of the liquid spraying system 9 are connected to the water pipe 19, and the spray heads 18 are installed on the U-shaped profile 17 of the screw-nut moving device 7, and the water pipe 19 is arranged inside the U-shaped profile 17. The rotating motor 10 of the rotating device 6 is connected to the worm 12 through the rotating motor coupling 11. The worm 12 meshes with the worm gear 13. The output shaft of the worm gear 13 is fixed to the rotating rod 46. The worm 12 and the worm gear 13 are respectively installed inside the worm and worm gear box 14, and the worm and worm gear box 14 and the rotating motor 10 are both fixed on the support frame 15. One side of the U-shaped mouth nut seat 21 of the screw-nut moving device 7 has a U-shaped mouth, which is stuck on the U-shaped profile 17 and can move up and down along the U-shaped profile 17. The nut screw 22 is fixed inside the U-shaped mouth nut seat 21. The nut screw 22 and the screw rod 20 form a screw-nut pair. One end of the screw rod 20 is connected to the output shaft of the moving motor 16. The support plate 26 and the bracket 23 form a rotating pair through the rotating pin 25. The pressure torsion spring 24 is sleeved on the rotating pin 25, and both sides of the pressure torsion spring 24 press on the support plate 26 and the bracket 23 respectively. The bracket 23 is fixed to the U-shaped mouth nut seat 21 through the fixing bolt 44. Summary of the Invention

[0024] Such asFigures 1-5 When the elderly need to take a bath, they first sit on the multi-functional deformable seat 3 and fasten the seat belt. The multi-functional deformable seat 3 transports the elderly from outside the bathroom to inside the bathroom. Then, the multi-functional deformable seat 3 makes the elderly change from a sitting state to a standing state through the first deformation, and firmly stabilizes the elderly comfortably and reliably through the seat backrest support. Next, during the process of the upper and lower body rotating and cleaning, scrubbing, massaging and spraying device spirally rotating closely to the body, water spraying, shower gel spraying, massaging, rubbing and rinsing are successively carried out on the upper and lower bodies to complete the cleaning actions of the upper and lower bodies. Subsequently, the multi-functional deformable seat 3 is deformed again, making the person slowly change from a standing state to a reclining state. During the deformation process, the support mesh pocket inside the seat backrest automatically opens, and the elderly lie semi-reclined on the support mesh pocket to prepare for washing the hair. Subsequently, the head cleaning and massaging device 1 moves forward to a suitable position through the conveying mechanism 4, and successively sprays water, shampoo, rubs like human hands, massages and rinses the head to complete the cleaning actions of the head. Finally, the multi-functional deformable seat 3 changes the elderly from a reclining state to a sitting state through the third deformation and sends the elderly out of the bathroom.

[0025] Such as Figures 1-12 The double gear rolling, rubbing, massaging and squeezing device 8 is driven by the rotating device 6 to rotate periodically and reciprocally. The double gear rolling, rubbing, massaging and squeezing device 8 is driven by the screw nut moving device 7 to move up and down. The spraying system 9 sprays water and rinses the person 5. The rotating brush 39 of the double gear rolling, rubbing, massaging and squeezing device 8 can apply the shower gel or skin care liquid in the shower cream (liquid) bag 32 onto the body of the person 5, and at the same time can rub the upper and lower bodies of the person 5. The massage stick 38 of the double gear rolling, rubbing, massaging and squeezing device 8 not only rolls and massages the body of the person 5, but also plays a good guiding role during the process of the whole device rotating and moving closely up and down. The elastic force of the pressure torsion spring 24 of the double gear rolling, rubbing, massaging and squeezing device 8 can make the massage stick 38 and the rotating brush 39 closely adhere to the body of the person 5.

[0026] In the rotating device 6, the power of the rotating motor 10 is transmitted through the worm 12 and the worm gear 13 to drive the rotating rod 46 to rotate circumferentially. The rotating rod 46 drives the screw nut moving device 7, the double gear rolling, rubbing, massaging and squeezing device 8 and the spraying system 9 connected thereto to rotate circumferentially. By controlling the forward and reverse rotation of the rotating motor 10, the rotating rod 46 and the screw nut moving device 7, the double gear rolling, rubbing, massaging and squeezing device 8 and the spraying system 9 thereon are driven to rotate periodically forward and backward.

[0027] During the reciprocating rotation of the double gear rolling, rubbing, massaging and squeezing device 8, the moving motor 16 drives the screw rod 20 to rotate. Through the transmission of the screw rod 20 and the nut 22, the nut 22 together with the U-shaped nut seat 21 moves up and down along the U-shaped profile 17, and the U-shaped nut seat 21 drives the double gear rolling, rubbing, massaging and squeezing device 8 to move up and down.

[0028] During the spiral rotation of the double-gear rolling, kneading, massaging and squeezing device 8, due to the torsion of the pressure torsion spring 24, the support plate 26 drives the massage stick 38 and the rotating brush 39 thereon to cling to the body of the person 5.

[0029] During the close-fitting spiral rotation of the double-gear rolling, kneading, massaging and squeezing liquid device 8, the top threaded end of the bath cream (liquid) bag 32 is first fixed to the threaded hole of the support plate 26, and the flat lower end is installed between the driving gear 46 and the driven gear 48. The double-ear nut 31 is twisted to rotate the driven gear frame 49 around the driving gear frame 30 through the screw 33. The driving gear 46 and the driven gear 48 clamp the flat lower end of the bath cream (liquid) bag 32, and then the rolling motor 28 is rotated. The rolling motor 28 drives the driving gear 46 to rotate. In the process of the driving gear 46 and the driven gear 48 meshing, the two meshing teeth roll and squeeze the bath cream (liquid) bag 32 between them, and the liquid (bagged shower gel, bagged shampoo, bagged skin care liquid) in the bath cream (liquid) bag 32 is slowly squeezed out, and the liquid passes through the hollow shaft of the rotating brush 39. The output is on the front surface of the rotating brush 39, and the kneading beads rotated by the rotating brush 39 are evenly applied to the body of the person 5. At the same time, the kneading beads of the rotating rotating brush 39 can knead the upper and lower body of the person 5. During the rolling and squeezing process of the rolling motor 28, the rolling motor 28 slowly moves toward the rotating brush 39 along the motor guide column 27 as the motor guide sleeve 42 overcomes the elastic force of the spring 29. When the bidirectional output motor 34 rotates, one output shaft thereon drives the rotating brush 39 to rotate via the driving bevel gear 41 and the driven bevel gear 40, and the other output shaft drives the massage stick 38 to rotate via the driving wheel 35, the belt 36 and the driven wheel 37. During the rotation of the massage stick 38, the massage beads thereon massage the person 5 closely, and the massage stick 38 can also guide the kneading and massaging ointment device 8 during the close spiral rotation process. When the liquid in the bath cream (liquid) bag 32 is squeezed out, the double-ear nut 31 is twisted in the opposite direction to remove the bath cream (liquid) bag 32 from between the driving gear 46 and the driven gear 48, and then the bath cream (liquid) bag 32 is screwed out of the threaded hole of the support plate 26. Under the action of the spring 28, the rolling motor 28 drives the driving gear 46 and the driving gear frame 30 to which it is fixed to reset.

[0030] During the close-fitting spiral rotation of the double-gear rolling and kneading massage squeezing device 8, the torsional force of the pressure torsion spring 24 can be used to make real-time adjustments to the convex and concave parts of the person 5's body. That is, when the body is convex, the double-gear rolling and kneading massage squeezing device 8 overcomes the elastic force of the pressure torsion spring 24 and swings outward; when the body is concave, it swings inward under the elastic force of the pressure torsion spring 24, ensuring that the rotating brush 39, massage stick 38 and other actuators are always in contact with the body surface during the massage and kneading process, and ensuring that the force is moderate.

[0031] When taking a bath for the upper and lower body, first, the liquid spraying system 9 sprays water on the person 5 during the reciprocating rotation of the rotating device 6. Then, the rotating device 6 and the screw-nut moving device 7 drive the double-gear rolling, kneading, massaging and squeezing device 8 to perform a spiral scanning rotation close to the body. The rotating brush 39 kneads and scrubs the body of the person 5 while applying body wash, and at the same time, the massage rod 38 performs a rolling massage close to the body. Subsequently, the liquid spraying system 9 rinses the body of the person 5 again, and finally, drying is carried out in the bathroom 4.
