[0023] Reference Figure 1-10 As shown, the present invention provides a technical solution for a straw for improving the bitter taste of medicine and a production device thereof: A straw for improving the bitter taste of medicine comprises a drinking water straw 13 and a medicine straw 2. The drinking water straw 13 is connected to the medicine straw 2, and the tail parts of the drinking water straw 13 and the medicine straw 2 are separately arranged.

[0024] In an optional embodiment, the drinking water straw 13 and the head of the medicine straw 2 are made into a whole through a plastic integral molding process.

[0025] In an optional embodiment, the drinking water straw 13 is connected to the head of the medicine straw 2 through the nozzle joint 1. The nozzle joint 1 is provided with an assembly port 11 for assembling the medicine straw 2. The side end of the nozzle joint 1 is provided with an outer frame tube 12. The drinking water straw 13 is located in the outer frame tube 12 and extends into the nozzle joint 1. The arc side surface of the outer frame tube 12 is located at the assembly port 11 and a mounting groove 14 is provided along the central axis of the nozzle joint 1 to assist in assembling the medicine straw 2 with the assembly port 11; refer to Figure 2 As shown, the assembly opening 11 is located at the edge of the nozzle connector 1 .

[0026] In an optional embodiment, the inner cross-sectional area of ​​the medicine suction straw 2 is 0.2 mm² to 10 mm², and the ratio of the sum of the inner cross-sectional area of ​​the medicine suction straw 2 and the inner cross-sectional area of ​​the drinking water suction straw 13 is 1:2 to 1:15.

[0027] It should be noted that the material of the nozzle joint 1, the outer frame tube 12, the drinking water straw 13 and the mounting groove 14 can be selected from medical grade polypropylene or polyethylene, and are made into a whole through an injection molding process. Among them, the injection molding process is an existing technology and will not be described in detail here.

[0028] Reference Figure 2 As shown, in an optional embodiment, the medicine suction tube 2 includes a straight tube 21 and a curved tube 24 , a sealing ring 23 is provided at the head of the straight tube 21 , a clamping ring 22 is sleeved on the straight tube 21 , and an oblique notch 25 is provided at the tail of the curved tube 24 .

[0029] It should be noted that the materials of the straight tube 21, the clamping ring 22 and the bent tube 24 can be polypropylene or polyethylene, and are also made into a whole by injection molding. Correspondingly, the material of the sealing ring 23 can be rubber, which has elasticity and can improve the sealing performance after the sealing ring 23 and the top pressure ring 6 are in contact. The setting of the oblique notch 25 makes the tail of the bent tube 24 sharp and used to pierce the liquid medicine packaging.

[0030] Reference Figure 7-10 As shown, in an optional embodiment: a sealing assembly is provided inside the suction nozzle joint 1 for assembling a drug pipette 2, including an inner chamber 5 arranged inside the suction nozzle joint 1 and located outside the assembly port 11, a top pressure ring 6 is provided at the end of the inner side wall of the assembly port 11 away from the outer frame tube 12, a side concave cavity 61 is provided on the inner side surface of the assembly port 11 facing the inner chamber 5, a vertical arc block 7 is provided on the inner side wall of the side concave cavity 61, and an oblique arc block 71 facing the top pressure ring 6 is obliquely provided at the end of the vertical arc block 7 close to the top pressure ring 6.

[0031] It should be noted that the inner diameter of the assembly port 11 is slightly larger than the outer diameter of the straight pipe 21 , and the outer diameter of the clamping ring 22 is equal to the inner diameter of the assembly port 11 . At the same time, the oblique arc block 71 extends into the assembly port 11 from the side concave cavity 61 .

[0032] Reference Figure 7-8 As shown, in an optional embodiment: the cross-section of the suction nozzle joint 1 is set to be circular or circular with a notch. When the cross-section of the suction nozzle joint 1 is set to be circular, the medicine suction straw 2 and the drinking water suction straw 13 are arranged in a plum blossom shape on the cross-section of the suction nozzle joint 1. When the cross-section of the suction nozzle joint 1 is set to be circular with a notch, the medicine suction straw 2 and the drinking water suction straw 13 are arranged in an arch shape on the cross-section of the suction nozzle joint 1.

[0033] It should be noted that the cross section of the nozzle connector 1 is set to be a circle with a notch, specifically: the cross section of the notch is a straight line segment and does not exceed the outer diameter of the nozzle connector 1, refer to Figure 8 shown.

[0034] When using the straw of the present invention, the suction force generated in the user's mouth acts on the medicine straw 2 and the drinking water straw 13 simultaneously through the mouthpiece connector 1. The tail of the medicine straw 2 pierces the medicine liquid packaging to suck out the medicine liquid, and the tail of the outer frame tube 12 is placed in the drinking water to suck out the drinking water. The medicine liquid and the drinking water will be briefly mixed, which not only reduces the bitterness of the medicine liquid due to dilution, but also, because the total flow rate of the drinking water straw 13 is larger, and the assembly port 11 is located at the edge of the mouthpiece connector 1 and is placed above the taste buds in the mouth when in use, a large amount of drinking water forms a water film on the taste buds. The suction force generated by the mouth of the medicine quickly passes through the water film, which significantly reduces the contact area and retention time of the medicine liquid and the taste buds, and greatly reduces the bitterness of the medicine liquid.

[0035] Reference Figure 1-10 As shown, a straw production equipment includes a bottom support block 3, and a placement groove 34 is opened along the width direction of one side end of the bottom support block 3 toward the other side end. There are several placement grooves 34 arranged along the length direction of the bottom support block 3, and the placement groove 34 passes through the top surface of the bottom support block 3. The width of the opening of the placement groove 34 at the top surface of the bottom support block 3 is smaller than the diameter of the placement groove 34, and the inner diameter of the placement groove 34 is equal to the outer diameter of the suction nozzle joint 1.

[0036] It should be noted that the production equipment also includes a pressing block 8, which is used to press the intersection of the straight pipe 21 and the curved pipe 24. Figure 3 As shown, the push block 33 is used to avoid the intersection of the straight tube 21 and the curved tube 24 on the medicine pipette 2 from breaking to the greatest extent during the process of pushing the medicine pipette 2, thereby reducing the production failure rate of the production equipment. The placement groove 34 is used to place the integrally formed suction nozzle connector 1, the outer frame tube 12, the drinking water straw 13 and the installation groove 14. The top surface of the bottom support block 3 is also provided with a control component for pushing the medicine pipette 2 and the suction nozzle connector 1 for assembly.

[0037] Reference Figure 1-10 As shown, in an optional embodiment, the control component includes a motor 31, a threaded shaft 32, a push block 33, a top block 35, a side block 36, a groove 37 and a clamping block 39. The motor 31 is arranged at the side end of the bottom support block 3 through the support plate 38. The threaded shaft 32 is fixedly connected to the output end of the motor 31. The push block 33 is threadedly connected to the threaded shaft 32. The top block 35 is arranged on the top surface of the bottom support block 3. The threaded shaft 32 is rotatably connected to the top block 35. The two symmetrical side ends of the push block 33 are provided with clamping blocks 39. The two symmetrical sides of the top surface of the bottom support block 3 are fixedly connected with side blocks 36. The side block 36 is provided with a groove 37 toward the side of the push block 33, and the clamping block 39 slides in the groove 37.

[0038] Reference Figure 1-10 As shown, the bottom supporting block 3 is provided with a limiting component 4 at the open end of the placement groove 34 for limiting the nozzle connector 1 from sliding out of the placement groove 34 .

[0039] In an optional embodiment, the limiting assembly 4 includes an end block 41 and a clamping plate 45. The end block 41 is provided with several external slots 43 that match the placement slot 34. The side of the end block 41 near the open end of the placement slot 34 is provided with a vertical slot 42. The end block 41 is located at the lower part of the inner wall of the vertical slot 42 and is provided with an inclined slot bottom opening 44. The clamping plate 45 can be placed in the vertical slot 42 or the inclined slot bottom opening 44.

[0040] The working principle of the device is now explained through the use process: when the device is used to assemble the drug pipette 2 and the nozzle connector 1, that is, the straight tube 21 is inserted into the assembly port 11 to complete the assembly of the drug pipette 2 and the nozzle connector 1. The specific operation method is as follows: First, adjust the device to the open mode through the limit assembly, that is, open the open end of the placement slot 34, the user only needs to lift the side of the bottom support block 3 close to the open end of the placement slot 34, and the card plate 45 will slide downward in the vertical slot 42 under the action of its own gravity. When the card plate 45 slides to the bottom opening 44 of the inclined slot, the user gently pushes the bottom of the card plate 45 to push the top of the card plate 45 into the bottom opening 44 of the inclined slot. At this time, refer to Figure 6 As shown, the clamping plate 45 can support one side of the bottom supporting block 3 close to the open end of the placement groove 34 and open the open end of the placement groove 34.

[0041] Since the suction nozzle joint 1, the outer frame tube 12, the drinking water straw 13 and the mounting groove 14 are made by the plastic one-piece molding process in the prior art, the main component will be used to replace the entirety of the suction nozzle joint 1, the outer frame tube 12, the drinking water straw 13 and the mounting groove 14 below.

[0042] The setting of the limit component 4, by supporting the side of the bottom supporting block 3 close to the open end of the placement groove 34, makes it easy for the user to push the main component into the placement groove 34 from the open end of the placement groove 34, thereby improving the assembly efficiency of the suction nozzle joint 1 and the drug pipette 2 in the main component. At the same time, by slightly lifting the bottom supporting block 3 and then pushing the bottom of the clamping plate 45 in the opposite direction, the clamping plate 45 can be restored to the vertical slot 42, and then slightly pushing the clamping plate 45 upward and leveling the bottom supporting block 3, the closing of the open end of the placement groove 34 is completed, and then the next step can be carried out. The operation process is simple and suitable for the assembly of the suction nozzle joint 1 and the drug pipette 2 in large quantities of main components, that is, the production of the straws for improving the bitterness of the medicine in the present invention, thereby improving the production efficiency of the straws.

[0043] Several main components are pushed into the placement groove 34, the nozzle joint 1 is located at the open end of the placement groove 34, the mounting groove 14 is placed upward, the clamping plate 45 is restored to its original state, the open end of the placement groove 34 is closed, and the bottom support block 3 is laid flat. Several drug suction tubes 2 are respectively placed in the mounting groove 14, that is, the straight tube 21 is placed in the mounting groove 14, and the bent tube 24 is attached to the top surface of the push block 33. At this time, the control component is started, that is, the motor 31 is started, which drives the rotation of its output end. Due to the push block 33 The push block 33 is threadedly connected to the threaded shaft 32, so that the push block 33 moves toward the open end of the placement groove 34, thereby pushing the straight pipe 21 into the assembly port 11 along the installation groove 14 until the sealing ring 23 abuts against the top pressure ring 6. In this process, due to the setting of the inner chamber 5, when the straight pipe 21 enters the assembly port 11, the clamping ring 22 squeezes the oblique arc block 71 and tends to squeeze the inner side wall of the side concave cavity 61 close to the inner chamber 5, thereby greatly reducing the clamping ring 22 on the suction nozzle. The degree of extrusion of the drinking water straw 13 in the joint 1 makes the inner diameter of the drinking water straw 13 hardly change due to the assembly of the suction nozzle joint 1 and the drug suction straw 2, thereby improving the production quality of the straw in the present invention. The arrangement of the vertical arc block 7 and the oblique arc block 71 not only cooperates with the clamping ring 22 to form a self-locking, so that the sealing ring 23 presses against the top pressure ring 6 to complete the seal, but when the straight tube 21 is subjected to an external force and tends to be pulled out of the assembly port 11, the clamping ring 22 will squeeze the oblique arc block 71 to make it tend to move downward. At this time, due to the arrangement of the vertical arc block 7, the contact area between the vertical arc block 7 and the side concave cavity 61 outside the inner chamber 5 is large. Under the reaction of the air in the inner chamber 5, the vertical arc block 7 will be difficult to be squeezed into the inner chamber 5, thereby making it difficult for the clamping ring 22 to pass through the oblique arc block 71, which greatly improves the stability of the straight tube 21 in the assembly port 11, thereby significantly improving the assembly quality of the suction nozzle joint 1 and the drug suction straw 2, that is, improving the production quality of the straw. It should be noted that, when the straight tube 21 enters the assembly port 11, the clamping ring 22 only needs to rotate the oblique arc block 71 around the connection between the oblique arc block 71 and the vertical arc block 7 at a small angle to pass through the oblique arc block 71. However, when the straight tube 21 moves away from the assembly port 11, the oblique arc block 71 needs to rotate a larger angle to allow the clamping ring 22 to pass.

[0044] After the nozzle connector 1 and the medicine pipette 2 are assembled, the opening end of the placement groove 34 is opened by the limiting component 4 and the medicine pipette 2 can be taken out.

[0045] This equipment successfully realizes the assembly of multiple sets of nozzle joints 1 and drug straws 2 through the setting and joint cooperation of the bottom support block 3, the limit component 4 and the control component. At the same time, it is easy to operate and has a high degree of automation, which greatly improves the production efficiency of the straws and is suitable for promotion and application in the process of large-scale production of straws.

[0046] The present straw is provided with a sealed assembly component, and when the straight tube 21 enters the assembly port 11, the inner side wall of the side concave cavity 61 close to the inner chamber 5 is more easily squeezed, so that the inner diameter of the drinking water straw 13 hardly changes due to the assembly of the suction nozzle joint 1 and the medicine suction nozzle 2, thereby ensuring the flow rate of the drinking water straw 13 during the use of the straw, thereby improving the production quality of the straw. At the same time, the arrangement of the vertical arc block 7 and the oblique arc block 71 is utilized, which not only cooperates with the clamping ring 22 to form a self-locking, but also, under the reaction of the air in the inner chamber 5, the contact area between the vertical arc block 7 and the side concave cavity 61 outside the inner chamber 5 is large, making it difficult for the vertical arc block 7 to be squeezed into the inner chamber 5, thereby making it difficult for the clamping ring 22 to pass through the oblique arc block 71, thereby greatly improving the assembly quality of the suction nozzle joint 1 and the medicine suction nozzle 2, further significantly improving the production quality of the straw, and making the straw more durable.
