[0016] As a preferred technical solution of the present invention, a cable is arranged at the bottom of the mounting seat, a handheld remote controller is arranged at the bottom of the cable, and the handheld remote controller is electrically connected to the linear electric push rod and the servo motor through the cable.

[0017] The beneficial effects of the present invention are:

[0018] The support arm of the present invention is supported by the support legs, so that the support arm can be placed above the elderly person's bed. The elderly person lies on his back on the bed and holds the handheld remote control, and uses the handheld remote control to control the linear electric push rod to push the bottom support plate downward to lift and lower, so that the esophagus at the bottom of the bottom support plate can be dropped down into the mouth of the elderly person lying on his back on the bed. The linear electric push rod controls the lifting speed of the esophagus to be stable, and it can be firmly self-locked after dropping to any position, so that the esophagus can be lifted to a suitable height for the elderly person's mouth to hold and bite the esophagus, avoiding the need for the elderly person lying on his back on the bed to lift his head, thereby reducing the power expenditure of the elderly person lying on his back on the bed during eating.

[0019] The present invention controls the rotation of an auger roller through a servo motor, and the rotation of the auger roller transports the liquid food through a liquid food delivery tube to a food storage bag containing an esophagus for food storage. When an elderly person lying on his back on the hospital bed bites the bottom of the esophagus with his mouth, the outer wall of the esophagus detects that the elderly person's mouth is biting the esophagus through a pressure-sensitive sensor, and the servo motor controls the auger roller to rotate to inject liquid food into the food storage bag. Because the esophagus is made of silicone and has good stretchability, during the process of injecting liquid food into the food storage bag, after a certain amount of liquid food is injected into the food storage bag, the food squeezing port will be pushed open, and the liquid food will enter the mouth of the elderly person lying on the hospital bed from the food squeezing port. At this time, after the elderly person's mouth contains food, his mouth will release the esophagus, and when the pressure-sensitive sensor of the outer wall of the esophagus cannot detect pressure from external objects, the servo motor will stop rotating. When the elderly person puts the esophagus in his mouth again, the pressure-sensitive sensor will detect it, and the servo motor will control the auger roller to continue rotating and continue to inject liquid food into the food storage bag. The liquid food entering the food storage bag will expand the feeding opening, so that the elderly person can put the liquid food in his mouth again. By repeating this step, the liquid food for the elderly can be completed.

[0020] The present invention can adjust the number of revolutions of the servo motor through a handheld remote controller, control the extension or contraction of the linear electric push rod, and control the start and stop of the servo motor through a pressure-sensitive sensor, thereby realizing throttling, speed adjustment, and feeding start and stop processes during the feeding process of the elderly, thereby enabling the elderly to independently operate the feeding process.

[0021] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Specifically, in this embodiment, the support arm 6 of the present invention is supported by the support leg 2, so that the support arm 6 can be placed above the elderly person's bed. The elderly person lies on his back on the bed, holds the handheld remote control 13, and uses the handheld remote control 13 to control the linear electric push rod 7 to push the bottom support plate 16 downward to lift it up and down, so as to facilitate the esophagus 18 at the bottom of the bottom support plate 16 to drop down into the mouth of the elderly person lying on his back on the bed. The linear electric push rod 7 controls the lifting speed of the esophagus 18 to be stable, and it can be firmly self-locked after dropping to any position, so that the esophagus 18 can be lifted to a suitable height for the elderly person's mouth to hold and bite the esophagus 18, avoiding the need for the elderly person lying on his back on the bed to lift his head, thereby reducing the energy expenditure of the elderly person lying on his back on the bed during eating.

[0046] Specifically, in the present embodiment, the present invention controls the rotation of the auger roller 31 through the servo motor 20, and the auger roller 31 rotates to transport the liquid food through the liquid food delivery tube 14 to the food storage bag 28 containing the esophagus 18 for food storage. When the elderly person lying on his back on the hospital bed bites the bottom of the esophagus 18 with his mouth, the outer wall of the esophagus 18 detects that the elderly person's mouth is biting the esophagus 18 through the pressure-sensitive sensor 19, and the servo motor 20 controls the auger roller 31 to rotate to inject liquid food into the food storage bag 28. Because the esophagus 18 is made of silicone and has good stretchability, during the process of injecting liquid food into the food storage bag 28, after a certain amount of liquid food is injected into the food storage bag 28, the food squeezing port 30 will be pushed open, and the liquid food will enter the mouth of the elderly person lying on the hospital bed from the food squeezing port 30. At this time, after the elderly person's mouth contains food, his mouth will release the esophagus 18, and when the pressure-sensitive sensor 19 on the outer wall of the esophagus 18 cannot detect the pressure of foreign objects, the servo motor 20 will stop rotating. When the elderly person's mouth holds the esophagus 18 again, the pressure-sensitive sensor 19 will detect it, and the servo motor 20 will control the auger roller 31 to continue rotating and continue to inject liquid food into the food storage bag 28. The liquid food entering the food storage bag 28 will expand the feeding opening 30, so that the elderly person's mouth can hold the liquid food again. By repeating this step, the liquid food for the elderly can be completed.

The middle of the licking groove 29 is provided with a food squeezing port 30 connected to the inside of the food storage bag 28.

[0051] Two pressure-sensitive sensors 19 are disposed on the outer wall of the esophagus containing tube 18 near the bottom of the esophagus containing tube 18 , and the two pressure-sensitive sensors 19 are symmetrically disposed on the left and right sides of the esophagus containing tube 18 .

[0052] The present invention controls the rotation of the auger roller 31 through the servo motor 20. The auger roller 31 rotates to transport the liquid food through the liquid food delivery tube 14 to the food storage bag 28 containing the esophagus 18 for food storage. When the elderly person lying on his back on the hospital bed bites the bottom of the esophagus 18 with his mouth, the outer wall of the esophagus 18 detects that the elderly person's mouth is biting the esophagus 18 through the pressure-sensitive sensor 19. The servo motor 20 controls the auger roller 31 to rotate and inject the liquid food into the food storage bag 28. Because the esophagus 18 is made of silicone and has good stretchability, during the process of injecting liquid food into the food storage bag 28, after a certain amount of liquid food is injected into the food storage bag 28, the food squeezing port 30 will be pushed open, and the liquid food will enter the mouth of the elderly person lying on the hospital bed from the food squeezing port 30. At this time, after the elderly person's mouth contains food, his mouth will release the esophagus 18, and when the pressure-sensitive sensor 19 on the outer wall of the esophagus 18 cannot detect the pressure of foreign objects, the servo motor 20 will stop rotating. When the elderly person's mouth holds the esophagus 18 again, the pressure-sensitive sensor 19 will detect it, and the servo motor 20 will control the auger roller 31 to continue rotating and continue to inject liquid food into the food storage bag 28. The liquid food entering the food storage bag 28 will expand the feeding opening 30, so that the elderly person's mouth can hold the liquid food again. By repeating this step, the liquid food for the elderly can be completed.

[0053] A cable 12 is disposed at the bottom of the mounting seat 9 , and a handheld remote controller 13 is disposed at the bottom of the cable 12 . The handheld remote controller 13 is electrically connected to the linear electric push rod 7 and the servo motor 20 through the cable 12 .
