The motor 801 is fixedly connected to the inside of the fixed base 2, and the output end of the motor 801 is fixedly connected to a guide tooth 12 through a coupling. The guide tooth 12 is engaged with one side of the surface of the arc plate 802. The arc plate 802 is slidably connected to the inside of the fixed base 2. The magnetic block 803 is fixedly connected to one side of the surface of the arc plate 802. One side of the surface of the infusion head 6 is fixedly connected to a magnet 13, and the magnet 13 can be magnetically connected to the magnetic block 803. Two connecting grooves 28 are symmetrically opened on the surface of the arc plate 802. Two connecting strips 29 are symmetrically fixedly connected to the inside of the fixed base 2. The arc plate 802 is slidably connected to the connecting strip 29 through the connecting groove 28.

[0039] Among them, the two sides of the sealed bag for containing the medicine are fixed by the fixing seat 2, and the opening is kept in an open state. When the fixing seat 2 slides along the infusion frame 1 to the bottom of the connecting frame 3, the connecting frame 3 slides downward to its bottom and enters the interior of the sealed bag. At this time, the infusion tube 4 descends, forcing the hose 5 and the infusion head 6 to descend together into the interior of the sealed bag. At this time, the magnet 13 on the surface of the infusion head 6 will form a magnetic connection with the magnetic block 803 on the surface of the arc plate 802. The guide tooth 12 is driven to rotate by the motor 801, thereby forcing the arc to rotate along the connecting strip 29. As the arc plate 802 rotates, the lower end portion of the sealed bag can be forced to produce a bending effect, and at this time the infusion head 6 will also follow the movement. The soft nature of the hose 5 itself can ensure the bending effect between the infusion head 6 and the infusion tube 4.

[0040] The rotating mechanism 9 is rotatably connected to the surface of the infusion head 6. The rotating mechanism 9 is used to drive the connecting ring 7 to rotate. The rotating mechanism 9 includes a gear ring 901, a rotating tooth 902 and a connecting shaft 903. The gear ring 901 is rotatably connected to the surface of the infusion head 6. The rotating tooth 902 is meshed with one side of the gear ring 901. A positioning seat 14 is fixedly connected to the surface of the infusion head 6. The connecting shaft 903 is rotatably connected to the positioning seat 14, and both ends of the connecting shaft 903 are respectively penetrated by both sides of the positioning seat 14. One end of the connecting shaft 903 is fixedly connected to the rotating tooth 902, and the other end of the connecting shaft 903 is fixedly connected to the connecting ring 7. A liquid outlet bag 15 is fixedly connected to one side of the connecting ring 7. A plurality of water outlet holes are provided on the surface of the liquid outlet bag 15. A push rod 16 is hinged on the top of the gear ring 901. The other end of the push rod 16 is hinged to the bottom end of the infusion tube 4, and the push rod 16 is located outside the hose 5.

[0041] In the process of the infusion head 6 following the curved plate 802 to bend, the distance between the center point of the infusion head 6 and the bottom end of the infusion tube 4 will decrease. At this time, the push rod 16 will push the tooth ring 901 to rotate on the surface of the infusion head 6, and drive the rotating tooth 902 to rotate. At this time, the rotating tooth 902 will drive the connecting ring 7 to rotate through the connecting shaft 903, forcing the connecting ring 7 and the liquid outlet bag 15 to rotate from the original state of being in contact with the infusion head 6 to a state of being separated from the infusion head 6. Since the curved tube is in a bent state, the separation of the liquid outlet bag 15 from the infusion head 6 can ensure the normal liquid outlet speed of the liquid outlet head, and can ensure that the port of the liquid outlet head in contact with the connecting ring 7 can be as close to the inner wall of the sealing bag as possible, forcing the liquid discharged through the infusion head 6 to impact on the inner wall of the sealing bag, which can effectively reduce the bubbles generated during the submerged filling.

[0042] In addition, as the filling work continues, in order to prevent liquid leakage, the sealing bag needs to maintain a vertical state to expand its volume. At this time, the infusion head 6 and the infusion tube 4 maintain a vertical state in the up and down directions. At this time, the distance between the bottom end of the infusion tube 4 and the center point of the infusion head 6 becomes larger. At this time, the push rod 16 will drive the gear ring 901 to rotate in the opposite direction, thereby driving the connecting shaft 903 to rotate in the opposite direction through the rotating gear 902, which can force the connecting ring 7 and the liquid outlet bag 15 to fit again on the port of the infusion head 6. At this time, the medicine delivered through the infusion tube 4 can be first injected into the liquid outlet bag 15 to form a buffering effect, and the diversion effect of the liquid outlet bag 15 can reduce the impact force of the medicine, further suppressing the generation of bubbles during filling.

[0043] Defoaming mechanism 10, the defoaming mechanism 10 is rotatably connected to the inside of the connecting frame 3, the defoaming mechanism 10 is used to eliminate a small amount of bubbles on the upper layer of the liquid, the defoaming mechanism 10 includes a connecting box 101, three shifting blocks 102 and a striking block 103, the connecting box 101 is slidably connected to the inside of the connecting frame 3, and the connecting box 101 and the bottom of the connecting frame 3 are penetrated, the connecting box 101 and the infusion tube 4 are penetrated, and the connecting box 101 and the infusion tube 4 are slidably connected, the three shifting blocks 102 are evenly arranged at the bottom of the connecting box 101, the shifting blocks 102 are slidably connected to the bottom of the surface of the connecting box 101, the striking block 103 is fixedly connected to the bottom of the connecting box 101, and the striking block 103 is slidably connected to the shifting block 102, the transmission mechanism 11, the transmission mechanism 11 is used to drive the defoaming mechanism 10 to rotate, the transmission mechanism 11 is arranged inside the connecting frame 3, and the transmission mechanism 11 includes a toothed disc 111 and a bevel gear 112 And connecting teeth 113, the toothed disc 111 and the bevel gear 112 are all rotatably connected to the inside of the connecting box 101, and the three shift blocks 102 are evenly fixedly connected to the bottom of the toothed disc 111 in a circular manner, and the bevel gear 112 is meshed with the top of the toothed disc 111. One side of the surface of the rotating tooth 902 is fixedly connected with a tooth sleeve 17, and the inside of the tooth sleeve 17 is unidirectionally meshed with a ratchet 18, and one side of the surface of the ratchet 18 is fixedly connected with a rotating shaft 19, and the other end of the rotating shaft 19 passes through the outside of the connecting box 101, and one end of the rotating shaft 19 that passes through the outside of the connecting box 101 is fixedly connected to the connecting teeth 113, and one side of the surface of the infusion tube 4 is fixedly connected with a tooth rod 20, and the tooth rod 20 is slidably connected to the middle part of the connecting box 101, and the tooth rod 20 can mesh with the connecting teeth 113, and the top of the connecting frame 3 is fixedly connected with a driver 21, and a tooth groove 22 is provided on one side of the surface of the infusion tube 4, and the output end of the driver 21 is meshed with the tooth groove 22 through a gear.

[0044] When filling, the driver 21 first drives the infusion tube 4 and the infusion head 6 to slide downward along the middle of the connection box 101 through the tooth groove 22, and after the filling is completed, the infusion tube 4 and the infusion head 6 can be driven to slide upward through the reverse operation of the driver 21. When sliding downward, since the ratchet 18 and the gear sleeve 17 are in a one-way meshing connection state, the gear sleeve 17 will not drive the bevel gear 112 to rotate. On the contrary, during the rising process of the infusion tube 4, the gear rod 20 will drive the connecting tooth 113 to rotate, thereby driving the rotating shaft 19 to rotate. The ratchet 18 rotates, and the ratchet 18 and the gear sleeve 17 can mesh smoothly. That is, the bevel gear 112 will rotate with the gear sleeve 17, and drive the gear disk 111 at the bottom thereof to rotate, thereby driving the three shifting blocks 102 at the bottom of the connecting box 101 to rotate, which can slowly stir the liquid in the upper layer of the sealing bag, push a small amount of bubbles in the upper layer of the liquid to the position of the impact block 103, and physically defoam the bubbles in the liquid by means of impact, so as to reduce the bubble content in the sealing bag, ensure the stability of subsequent packaging work, and prevent overflow.

[0045] Two cylinders 23 are symmetrically fixedly connected to the two sides of the top of the connecting box 101, and the other end of the cylinder 23 is fixedly connected to the connecting frame 3. Four expansion blocks 24 are evenly embedded in the surface of the connecting frame 3. The expansion blocks 24 slide through the connecting frame 3. The surface of the expansion block 24 close to the connecting box 101 is hinged with a push rod 25, and the other end of the push rod 25 is hinged to the surface of the connecting box 101. Slide grooves 26 are provided on the upper and lower sides of the surface of the expansion block 24. The upper and lower sides of the expansion block 24 are symmetrically slidably connected with connecting blocks 27. One end of the two connecting blocks 27 is hinged to the inside of the connecting frame 3, and the other ends of the two connecting blocks 27 are slidably connected to the expansion block 24 through two slide grooves 26 respectively.

[0046] Among them, after the bottom of the connecting frame 3 enters the interior of the sealing bag, the connecting box 101 is pushed down by the cylinder 23. During the descending process of the connecting box 101, the expansion block 24 will be pushed by the push rod 25 to expand toward the outside of the connecting frame 3. At this time, the connecting blocks 27 on the upper and lower sides of the expansion block 24 will have the effect of hinged rotation with the interior of the connecting frame 3, and the other end of the connecting block 27 will slide along the slide groove 26 and the surface of the expansion block 24, so as to connect and support the outwardly extending expansion block 24, ensure the stable expansion of the expansion block 24 and facilitate its retraction, and support the expansion near the opening of the sealing bag to ensure the smooth rotation of the defoaming mechanism 10.

[0047] The specific working principle and use method of the present invention are explained in detail below: When in use, the first step is to fix the two sides of the sealed bag for containing the medicine by the fixing seat 2, and keep the opening in an open state. When the fixing seat 2 slides along the infusion frame 1 to the bottom of the connecting frame 3, the connecting frame 3 slides downward to its bottom and enters the interior of the sealed bag. At this time, the infusion tube 4 descends, forcing the hose 5 and the infusion head 6 to descend together into the interior of the sealed bag. At this time, the magnet 13 on the surface of the infusion head 6 will form a magnetic connection with the magnetic block 803 on the surface of the arc plate 802. The guide tooth 12 is driven to rotate by the motor 801, thereby forcing the arc to rotate along the connecting strip 29. As the arc plate 802 rotates, the lower end portion of the sealed bag can be forced to produce a bending effect, and at this time the infusion head 6 will also follow the movement. The soft nature of the hose 5 itself can ensure that the infusion head 6 and the infusion tube 4 produce a bending effect.

[0048] In the second step, when the infusion head 6 follows the curved plate 802 to bend, the distance between the center point of the infusion head 6 and the bottom end of the infusion tube 4 will decrease. At this time, the push rod 16 will push the tooth ring 901 to rotate on the surface of the infusion head 6, and drive the rotating tooth 902 to rotate. At this time, the rotating tooth 902 will drive the connecting ring 7 to rotate through the connecting shaft 903, forcing the connecting ring 7 and the liquid outlet bag 15 to rotate from the original state of being in contact with the infusion head 6 to a state of being separated from the infusion head 6. Since the curved tube is in a bent state, the separation of the liquid outlet bag 15 from the infusion head 6 can ensure the normal liquid outlet speed of the liquid outlet head, and can ensure that the port of the liquid outlet head in contact with the connecting ring 7 can be as close to the inner wall of the sealing bag as possible, forcing the liquid discharged through the infusion head 6 to impact on the inner wall of the sealing bag, which can effectively reduce the bubbles generated during the submerged filling.

[0049] The third step, as the filling work is continuously carried out, in order to prevent the liquid from leaking out, the sealed bag needs to maintain a vertical state to expand its volume. At this time, the infusion head 6 and the infusion tube 4 maintain a vertical state in the up and down directions. At this time, the distance between the bottom end of the infusion tube 4 and the center point of the infusion head 6 becomes larger. At this time, the push rod 16 will drive the gear ring 901 to rotate in the opposite direction, thereby driving the connecting shaft 903 to rotate in the opposite direction through the rotating gear 902, which can force the connecting ring 7 and the liquid outlet bag 15 to fit the port of the infusion head 6 again. At this time, the liquid medicine transported through the infusion tube 4 can be first injected into the liquid outlet bag 15 to form a buffer effect, and the shunting effect of the liquid outlet bag 15 can reduce the impact force of the liquid medicine, further suppressing the generation of liquid bubbles during filling;

[0050] In the fourth step, during filling, the driver 21 first drives the infusion tube 4 and the infusion head 6 to slide downward along the middle of the connection box 101 through the tooth groove 22, and after the filling is completed, the infusion tube 4 and the infusion head 6 can be driven to slide upward through the reverse operation of the driver 21. When sliding downward, since the ratchet 18 and the gear sleeve 17 are in a one-way meshing connection state, the gear sleeve 17 will not drive the cone gear 112 to rotate. On the contrary, during the rising process of the infusion tube 4, the gear rod 20 will drive the connecting tooth 113 to rotate, thereby driving the rotating shaft 19 to drive the connecting tooth 113 to rotate. The movable ratchet 18 rotates, and the ratchet 18 and the gear sleeve 17 can mesh smoothly. That is, the bevel gear 112 will rotate with the gear sleeve 17, and drive the gear disk 111 at the bottom thereof to rotate, thereby driving the three shifting blocks 102 at the bottom of the connecting box 101 to rotate, which can slowly stir the liquid in the upper layer of the sealing bag, push a small amount of bubbles in the upper layer of the liquid to the position of the impact block 103, and physically defoam the liquid bubbles by means of impact, so as to reduce the bubble content in the sealing bag, ensure the stability of subsequent packaging work, and prevent overflow.

[0051] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
