Therefore, it should not be construed as a limitation to the present invention.

[0032] Embodiment:

[0033] Referring to Figures 1-8 , a liquid food booster, comprising: a feeding assistance module 1, including a mounting support plate 101, on which a driving motor 102 is arranged. The output end of the driving motor 102 is connected to a lead screw shaft 103. A guide rail 104 is fixedly connected to one side of the mounting support plate 101 close to the lead screw shaft 103. A moving module 105 that is slidably connected to the guide rail 104 is arranged on the lead screw shaft 103; an injection module 4, arranged on the mounting support plate 101, wherein a stirring assembly is arranged on the injection module 4. When the moving module 105 drives a part of the structure of the injection module 4 to move, the liquid food in the injection module 4 can be stirred. The feeding assistance module 1 is electrically connected to the injection module 4; a lubricating assembly, arranged between the moving module 105 and the injection module 4. When the injection module 4 is heated, lubricating oil can be added to the surface of the lead screw shaft 103 through the lubricating assembly to reduce the friction between the moving module 105 and the lead screw shaft 103. It further includes a vibration module 2, which includes a housing and a vibration motor 201. A plurality of eccentric wheel assemblies 202 are arranged on the housing. Synchronous wheels 204 are arranged on both the output end of the vibration motor 201 and the eccentric wheel assemblies 202. A synchronous belt 203 is sleeved between the synchronous wheel 204 on the vibration motor 201 and the synchronous wheel 204 on the eccentric wheel assemblies 202. The eccentric wheel assemblies 202 are connected to the mounting support plate 101. It further includes a human-machine interaction module 3, fixedly connected to the housing of the vibration module 2, including a touch screen, a switch, an emergency stop switch, etc., for controlling the driving motor 102, the vibration motor 201, a temperature sensor 111 and a pressure sensor 112. A housing is arranged on the mounting support plate 101. A support and a floor are arranged at the bottom of the housing of the vibration module 2. A connecting member is arranged between the vibration module 2 and the feeding assistance module 1. A charging interface electrically connected to the human-machine interaction module 3 is arranged on the housing.

[0034] Referring to Figure 2 , Figure 4 and Figure 7, the moving module 105 includes a guiding block 105a arranged on the lead screw shaft 103. The guiding block 105a includes a fixed part and a movable part. The fixed part and the movable part are slidably connected. A lead screw groove 1050 matching the lead screw shaft 103 is formed in the inner wall of the movable part. A circulation hole 1051 communicating with the lead screw groove 1050 is formed inside the movable part. A deflector 1052 is connected to one side of the movable part close to the end of the circulation hole 1051. A plurality of sets of balls 1053 are arranged between the circulation hole 1051 and the lead screw shaft 103.

[0035] The connection mode between the lead screw shaft 103 and the balls 1053 is a conventional means in the prior art, so it will not be elaborated here. When the driving motor 102 drives the lead screw shaft 103 to rotate, the guiding block 105a is driven to move along the lead screw shaft 103 under the action of the balls 1053 and the guide rail 104. And the balls 1053 will roll along the circulation hole 1051 and the lead screw groove 1050, and under the action of the deflector 1052, the circulation of the balls 1053 in the circulation hole 1051 and the lead screw groove 1050 is ensured, so as to drive the injection piston 42 to move along the injection shell 41 to feed the patient with liquid food.

[0036] Refer to Figure 4 , it further includes a guiding groove 105b formed on the movable part. A spring group 105c slidably connected with the guiding groove 105b is arranged on the fixed part. The spring group 105c includes a positioning rod and a spring. The positioning rod is slidably connected with the guiding groove 105b. The spring is fixedly connected between the fixed part and the movable part, and the spring is sleeved on the positioning rod. A pressure sensor 112 is arranged on the fixed part.

[0037] The specific structure of the pressure sensor 112 can refer to the technical solutions in the prior art. Those skilled in the art can know it, so it will not be elaborated here. When feeding the patient with liquid food, the fixed part of the guiding block 105a moves along the lead screw shaft 103, and at the same time drives the movable part of the guiding block 105a to move, and compresses the injection piston 42 through the movable part. During the compression process, if the resistance increases, the movable part of the guiding block 105a moves towards the side of the spring group 105c, so as to detect the feeding speed of the patient and improve the feeding safety and comfort of the patient.

[0038] Refer to Figure 1 , Figure 3 and Figure 6 , the injection module 4 includes an injection shell 41 fixedly connected to the installation support plate 101. An injection piston 42 is slidably connected inside the injection shell 41. An injection head 43 is communicated with the side of the injection shell 41 far from the injection piston 42. The outer wall of the injection piston 42 is closely attached to the inner wall of the injection shell 41. A pressing disc 113 matching the injection shell 41 is arranged on the installation support plate 101.

[0039] The dimensions of the injection shell 41 and the injection piston 42 are not limited herein and can be adjusted according to the patient's demand for the convection food intake. Among them, a sealed connection method is adopted between the injection piston 42 and the injection shell 41. Moreover, in order to ensure the comfort of the patient during eating, the injection head 43 can be made of soft silicone material. When the injection piston 42 moves into the injection shell 41, the pressure inside the injection shell 41 will increase, so that the liquid food in the injection shell 41 is discharged through the injection head 43 to realize the patient's eating. During this process, the pressure plate 113 can press the injection shell 41 tightly on the installation support plate 101 to ensure the stability of eating.

[0040] Referring to Figures 1-2 , the feeding assistance module 1 further includes a limit switch 106 fixedly connected to the installation support plate 101. The limit switch 106 is rotatably connected to the lead screw shaft 103. A fixed seat 108 is fixedly connected to the movable part. A set screw 107 is arranged on the fixed seat 108. Among them, the fixed seat 108 is connected to the end of the injection piston 42 away from the injection shell 41, and the end of the set screw 107 passes through the fixed seat 108 and fits with the end of the injection piston 42.

[0041] The limit switch 106 is a conventional means in the prior art, so it will not be elaborated here. When the guide block 105a moves to contact the limit switch 106, the limit switch 106 will be triggered. The fixed seat 108 matches the end of the injection piston 42. The set screw 107 can adopt a structure such as a bolt. By rotating the set screw 107, the set screw 107 can gradually approach the injection piston 42, so as to press the end of the injection piston 42 tightly.

[0042] Referring to Figure 3 and Figure 6 , it further includes a heat conducting member 110 arranged on the outer wall of the injection shell 41. A heating sheet 109 is arranged on the side of the heat conducting member 110 away from the injection shell 41. A temperature sensor 111 is arranged on the side of the outer wall of the injection shell 41 close to the injection head 43. Among them, a heat conducting fluid is arranged inside the heat conducting member 110, and when the temperature of the heat conducting fluid rises, its volume increases.

[0043] The type of the heat conducting fluid is not limited herein. As long as it can store the heat generated by the heating sheet 109 during heating, transfer the heat to the side wall of the injection shell 41, and as the heat rises, the volume gradually increases, so as to heat the liquid food in the injection shell 41, and detect the temperature of the liquid food in the injection shell 41 through the temperature sensor 111 to improve the comfort of the patient during eating.

[0044] Referring to Figure 6, the stirring assembly includes a mounting plate 5 fixedly connected to the inner wall of the injection shell 41 near the injection head 43. A screw rod 6 is rotatably connected to the side of the mounting plate 5 close to the injection piston 42. A stirring blade 7 is fixedly connected to the outer wall of the screw rod 6 near the mounting plate 5. A screw hole 8 is formed in the side of the injection piston 42 close to the screw rod 6. A convex block matching the screw rod 6 is arranged inside the screw hole 8. A sealing ring 9 closely attached to the screw rod 6 is fixedly connected to the injection piston 42. An electromagnetic valve 10 is arranged inside the injection head 43. Among them, the electromagnetic valve 10 is electrically connected to the temperature sensor 111 and the pressure sensor 112, and the stirring blade 7 is spiral.

[0045] When the injection piston 42 moves into the injection shell 41, under the action of the screw hole 8, the screw rod 6 is driven to rotate, thereby driving the stirring blade 7 to rotate, stirring the liquid food in the injection shell 41 to avoid uneven temperature of the liquid food. If the liquid food fills the chamber between the injection piston 42 and the injection shell 41 and the temperature of the liquid food does not reach the set stability, the temperature sensor 111 and the pressure sensor 112 drive the drive motor 102 to rotate in the reverse direction, driving the injection piston 42 to move in the reverse direction until the liquid food reaches the set stability, then the liquid food can be compressed again, and the electromagnetic valve 10 is opened, so as to discharge the liquid food from the injection head 43 to realize the feeding of the patient.

[0046] Refer to Figure 6 and Figure 8 , the lubricating assembly includes a sealing cylinder 11 fixedly connected to the outer wall of the injection shell 41 near the heat conducting member 110. The sealing cylinder 11 is communicated with the heat conducting member 110. A moving pressure block 12 is slidably connected inside the sealing cylinder 11. A connecting pipe 13 is communicated with the side of the sealing cylinder 11 far from the heat conducting member 110.

[0047] It should be explained that the moving pressure block 12 and the sealing cylinder 11 are connected in a sealed manner. When the heating sheet 109 is heating, the temperature of the heat conducting fluid in the heat conducting member 110 rises, and at the same time the volume increases, driving the moving pressure block 12 to move towards the connecting pipe 13 side, compressing the gas between the moving pressure block 12 and the connecting pipe 13, and conveying the gas to between the diaphragm 1055 and the storage cavity 1054.

[0048] Refer to Figure 7 , it also includes a storage cavity 1054 arranged in the guide block 105a. One end of the connecting pipe 13 far from the sealing cylinder 11 is communicated with the storage cavity 1054. A diaphragm 1055 is arranged on the side of the storage cavity 1054 close to the connecting pipe 13. A pressure relief valve 1056 is arranged between the storage cavity 1054 and the circulation hole 1051. Among them, the diaphragm 1055 divides the storage cavity 1054 into two groups of sealed chambers. One group of sealed chambers is used to store lubricating oil, and the other group of sealed chambers is communicated with the connecting pipe 13, and the diaphragm 1055 is elastic.

[0049] An addition port communicating with the storage cavity 1054 is provided on the guiding block 105a, and a sealing cover is provided on the addition port. When the device is working, the addition port is in a sealed state. After the compressed gas in the sealing cylinder 11 is conveyed into the storage cavity 1054, it drives the diaphragm 1055 to extend towards the side storing lubricating oil, so that the sealing chamber on the side storing lubricating oil is in a compressed state. When the pressure reaches the threshold value, the internal lubricating oil is added into the circulation hole 1051 through the pressure relief valve 1056 to lubricate the ball 1053, thereby reducing the wear between the ball 1053 and the lead screw shaft 103 when the patient is eating. While ensuring the stable eating speed, it can also extend the service life of the device.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
