Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0038] Example 1: Please refer to Figure 1 , Figure 2 As shown, Embodiment 1 of this utility model provides a liquid addition system 10. Please refer to... Figure 3As shown, the liquid dispensing system 10 needs to be used in conjunction with the medicine box 20. The structure of the medicine box 20 can refer to the existing technology. Generally speaking, the medicine box 20 mainly consists of a main body and several cavities, which are arranged side by side at intervals.

[0039] The liquid dispensing system 10 is mainly used in medical sterilization and disinfection equipment. Its function is to puncture the capsules in the medicine box 20 inserted therein and draw out liquids such as hydrogen peroxide from the capsules.

[0040] The cavity is used to contain the capsule, which contains liquids such as hydrogen peroxide. The capsule can be made of existing technology, such as rubber or flexible plastic, and can be punctured.

[0041] The liquid addition system 10 mainly consists of a base 11, a feeding mechanism 12, and a needle-punching mechanism 14, with the feeding mechanism 12 and the needle-punching mechanism 14 mounted on the base 11.

[0042] Please combine Figure 4 As shown, the structure of the base 11 is not limited; it can be a flat plate, a workbench, or a box, etc. The material of the base 11 can be metal, plastic, wood, etc.

[0043] In this embodiment, the base 11 is provided with a first slide rail 110 and a second slide rail 111. The first slide rail 110 and the second slide rail 111 are arranged at an angle, that is, there is an angle between the extension directions of the first slide rail 110 and the second slide rail 111. The degree of the angle is not limited, such as 30°, 60°, 90°, etc. Preferably, the angle between the two is 90°, that is, the first slide rail 110 and the second slide rail 111 are perpendicular.

[0044] The style of the first slide rail 110 and the second slide rail 111 is not limited; for example, they can be grooves, guide rods, etc.

[0045] The feeding mechanism 12 can move left and right along the first slide 110 to change its relative position to the needle punching mechanism 14.

[0046] Please combine Figures 5-8 As shown, the feeding mechanism 12 includes a material rack 120 and a card reader 125. The material rack 120 is used to insert medicine boxes 20, and the card reader 125 is used to read product information or counts on the medicine boxes 20.

[0047] The structure of the material rack 120 is not limited, as long as it can insert and support the medicine box 20. In this embodiment, the following scheme can be adopted, but is not limited to: the material rack 120 includes a back plate, an upper truss, a lower truss, and a sealing plate.

[0048] The upper and lower trusses are positioned opposite each other at the upper and lower ends of the back plate. Strip grooves can be provided on opposite sides of the upper and lower trusses. The strip grooves are strip-shaped and their width is slightly greater than the thickness of the upper and lower ends of the medicine box 20.

[0049] A material cavity 121 for accommodating the medicine box 20 is formed between the upper truss and the lower truss. One end of the material cavity 121 is open and the other end is closed by a sealing plate.

[0050] The material chamber 121 has an opening at one end, which can be located at the left or right end of the material chamber 121. The medicine box 20 can be inserted into the material chamber 121 through the opening. The top end of the medicine box 20 is embedded in the strip groove of the upper truss, and the bottom end of the medicine box 20 is embedded in the strip groove of the lower truss. A needle-punching window is provided on the side of the material chamber 121 away from the back plate, and one side of the medicine box 20 is exposed through the needle-punching window to facilitate needle-punching operations by the needle-punching system.

[0051] The material chamber 121 is provided with a plurality of first needle rollers 123 and a plurality of second needle rollers 124. The number of first needle rollers 123 and second needle rollers 124 is not limited, for example, there can be two, three, four, etc. In this embodiment, there are seven first needle rollers 123 and two second needle rollers 124. The plurality of first needle rollers 123 are spaced apart and their center lines are parallel or substantially parallel, and the plurality of second needle rollers 124 are spaced apart and their center lines are parallel or substantially parallel.

[0052] Both the first needle roller 123 and the second needle roller 124 are cylindrical, and both the first needle roller 123 and the second needle roller 124 are rotatably supported on the material rack 120. The first needle roller 123 and the second needle roller 124 can rotate around their own center line.

[0053] A portion of the first needle roller 123 is exposed from the strip groove of the lower truss, and a portion of the second needle roller 124 is exposed from the strip groove of the upper truss. Both the first needle roller 123 and the second needle roller 124 are able to roll into contact with the medicine box 20.

[0054] The top of the medicine box 20 is provided with a slot, which extends along the rear end of the medicine box 20. The slot is V-shaped, meaning that both sides of the slot are inclined surfaces. The slot is recessed downwards relative to the top surface of the medicine box 20. The second roller needle 124 can move up and down, and the position and extension direction of the slot and the second roller needle 124 are consistent, meaning that the second roller needle 124 can fall into the slot and can also disengage from the slot. When the second roller needle 124 contacts the top of the medicine box 20, the two can roll in contact, facilitating the smooth insertion of the medicine box 20. When the second roller needle 124 reaches the slot, it can fall into the slot, thereby limiting the movement of the medicine box 20 and preventing abnormal movement of the medicine box 20, thus ensuring the accuracy of liquid dispensing.

[0055] Because the cross-section of the slot is V-shaped, the second needle roller 124 can roll along the inclined surface of the slot. When the second needle roller 124 enters the slot from the top surface of the medicine box 20, it can slowly reach the bottom of the slot along the inclined surface; when the second needle roller 124 leaves the slot, it can slowly reach the top surface of the medicine box 20 along the inclined surface.

[0056] A spring guide 130 is provided on the top side of the material rack 120. The spring guide 130 causes the second needle roller 124 to tend to move downward. The spring guide 130 can press the second needle roller 124 tightly against the top of the medicine box 20. When the second needle roller 124 enters the slot, the spring guide 130 can press it tightly into the slot. A certain force must be applied to pull the medicine box 20 out of the material rack 120.

[0057] The structure of the spring guide 130 is not limited. For example, the spring guide 130 is a spring, which is a compression spring, and the two ends of the spring abut against the material rack 120 and the second needle roller 124, respectively.

[0058] In this embodiment, the spring guide 130 has the following structure: the spring guide 130 includes a T-shaped member 131 and a return spring 132.

[0059] The T-shaped component 131 is slidably disposed within the first stepped hole 126. Specifically, the longitudinal cross-section of the T-shaped component 131 is an inverted T-shape, consisting of two segments: a first segment and a second segment. The first segment is located above the second segment. Each segment can be cylindrical or prismatic, etc. Taking a cylindrical shape as an example, the diameter of the second segment is larger than the diameter of the first segment. Correspondingly, the material rack 120 is provided with the first stepped hole 126, which is divided into at least two segments: a first hole and a second hole. The first hole and the second hole can be circular or square, etc. The first hole matches the first segment, and the second hole matches the second segment. The first segment can slide up and down within the first hole, and the second segment can slide up and down within the second hole. When the T-shaped component 131 slides up and down within the first stepped hole 126, it can move closer to or further away from the second needle roller 124.

[0060] The return spring 132 can be a compression spring or a tension spring. In this embodiment, the return spring 132 is a compression spring. The return spring 132 is sleeved on the first section of the T-shaped member 131, and the two ends of the return spring 132 abut against the step of the first stepped hole 126 and one end of the second section of the T-shaped member 131, respectively. Under no external force, the return spring 132 can press the T-shaped member 131 against the second needle roller 124, thereby pressing the second needle roller 124 against the top surface of the medicine box 20, or when the second needle roller 124 changes from the top surface of the medicine box 20 to the slot, it can firmly fix the second needle roller 124 in the slot. When the operator applies a certain force to pull the T-shaped member 131 upward, the return spring 132 is compressed, thereby causing the T-shaped member 131 to disengage from the second needle roller 124, or when the second needle roller 124 changes from the slot of the medicine box 20 to the top surface, it can push the T-shaped member 131 upward and compress the return spring 132. Of course, if the slot is not inserted into the material rack 120, the second needle roller 124 will also stop when moving downwards, and the return spring 132 can keep the second needle roller 124 at the lowest stop.

[0061] The material rack 120 and the first slide rail 110 are slidably engaged via a first ball screw mechanism. The structure of the first ball screw mechanism can refer to existing technology, and it mainly consists of a first screw and a first nut. The first screw and the first nut are threaded together. Both ends of the first screw are rotatably supported on the base 11. The first screw can rotate around its own center line. One end of the first screw is driven by a first motor. The type and model of the first motor are not limited, such as a DC motor or an AC motor. The output shaft of the first motor and the first screw can be coaxially driven or indirectly driven through a gear reducer. The first nut is fixed to the material rack 120. The first motor and the first ball screw mechanism can together form a first linear motor 112. When the first motor is energized, the output shaft of the first motor rotates, thereby driving the first screw to rotate around its own center line. Due to the sliding engagement between the material rack 120 and the first slide rail 110, and the rotational engagement between the first screw and the first nut, the material rack 120 slides left and right along the first slide rail 110.

[0062] The needle-punching mechanism 14 can move left and right along the second slide 111 to approach or move away from the medicine box 20 on the material rack 120.

[0063] The structure of the acupuncture mechanism 14 is not limited; please refer to [the specific details]. Figures 9-11As shown, it mainly consists of a needle frame 140 and a needle 141. The front end of the needle 141 is relatively sharp and can pierce the capsule. In addition, the front end of the needle 141 is provided with a through hole, which is hollow inside, so that the liquid inside the capsule can be extracted through the through hole and the internal cavity. The needle 141 and the needle frame 140 can be directly connected or indirectly connected through other structures. In this embodiment, the needle piercing mechanism 14 also includes a mounting bolt 142.

[0064] The needle holder 140 is provided with a second stepped hole 143, which includes at least two through holes, which can be round or square, etc. The needle 141 passes through a mounting bolt 142, and the tail end of the needle 141 communicates with the second stepped hole 143. The mounting bolt 142 is threadedly engaged with the first end of the second stepped hole 143. This arrangement facilitates the installation and removal of the needle 141. A pump can be connected to the second stepped hole 143 to enable negative pressure suction, thereby allowing the needle 141 to draw out the liquid from the capsule.

[0065] In some embodiments, a filter 144 is provided at the second end of the second stepped hole 143. The style of the filter 144 is not limited and can be a device in the prior art. The filter 144 is used to filter the liquid drawn into the second stepped hole 143 and can filter out some impurities.

[0066] The needle-piercing mechanism 14 and the second slide rail 111 are slidably engaged via a second ball screw mechanism. The structure of the second ball screw mechanism can refer to existing technology, and it mainly consists of a second screw and a second nut. The second screw and the second nut are threaded together, and both ends of the second screw are rotatably supported on the base 11. The second screw can rotate around its own center line. One end of the second screw is driven by a second motor. The type and model of the second motor are not limited, such as a DC motor or an AC motor. The output shaft of the second motor and the second screw can be coaxially driven or indirectly driven through a gear reducer. The second nut is fixed to the needle-piercing frame 140. The second motor and the second ball screw mechanism can together form a second linear motor 113. When the second motor is energized, the output shaft of the second motor rotates, thereby driving the second screw to rotate around its own center line. Due to the sliding engagement between the needle-piercing frame 140 and the second slide rail 111, and the rotational engagement between the second screw and the second nut, the needle-piercing frame 140 slides left and right along the second slide rail 111.

[0067] The card reader 125 is located adjacent to the needle-punching window. The card reader 125 is used to read the QR code information on the medicine box 20, or simply for technical purposes, or to detect the forward distance of the material rack 120. Of course, in some embodiments, the feeding mechanism 12 may not include the card reader 125 or may be replaced by other devices.

[0068] Limiting elements 122 are respectively provided at both ends of the bottom of the material rack 120. The limiting elements 122 are used to limit the left and right movement distance of the material rack 120. The shape of the limiting element 122 is not limited, such as block structure, plate structure, etc. A corresponding limiting part is provided on the base 11. When the limiting element 122 abuts against the limiting part, or when the distance sensor detects that the distance between the two reaches the preset range, it means that the material rack 120 has reached the stop point and cannot continue to move in the same direction.

[0069] A proximity switch 127 is provided at the end of the material chamber 121. The proximity switch 127 can be used to detect the position of the medicine box 20 or its relative position to the needle 141. The proximity switch 127 is a sensor that can detect objects without contact. There are many types, such as electromagnetic induction, capacitive, photoelectric, and Hall effect, which are commonly used electronic components and will not be described in detail here.

[0070] The working method of the liquid addition system 10 provided in this embodiment is as follows:

[0071] In the initial state, the material rack 120 is in the first position, at which time the needle 141 is away from the material rack 120;

[0072] The staff inserts the medicine box 20 into the material cavity 121 from one end of the material rack 120. The medicine box 20 contains multiple capsules arranged side by side. During this process, the upper and lower ends of the medicine box 20 are inserted into the strip grooves of the upper truss and the lower truss, respectively. The bottom surface of the medicine box 20 rolls in contact with the first roller needle 123, and the top surface of the medicine box 20 rolls in contact with the second roller needle 124. The top surface of the medicine box 20 pushes the second roller needle 124 upward, and the return spring 132 is compressed until the second roller needle 124 is engaged in the corresponding slot.

[0073] The first linear motor 112 is working, and the first motor drives the first lead screw to rotate, causing the material rack 120 to slide along the first slide rail 110 to one side.

[0074] When the material rack 120 reaches the designated position, the second linear motor 113 works, the second motor drives the second lead screw to rotate, causing the needle frame 140 to slide along the second slide rail 111, and causing the needle 141 to pierce into the corresponding capsule and suck out the liquid such as hydrogen peroxide from the capsule.

[0075] The second linear motor 113 operates, driving the second lead screw to rotate, which in turn causes the needle holder 140 to slide backward along the second slide rail 111, and causes the needle 141 to disengage from the corresponding capsule.

[0076] The first linear motor 112 is working, and the first motor drives the first lead screw to rotate, causing the material rack 120 to continue sliding a distance to one side along the first slide rail 110. At this time, the needle 141 targets the next capsule.

[0077] The second linear motor 113 operates, driving the second lead screw to rotate, which in turn causes the needle holder 140 to slide along the second slide rail 111, and causes the needle 141 to pierce the next corresponding capsule, and draw out the liquid such as hydrogen peroxide from the capsule.

[0078] Repeat the above steps until all the liquid inside the capsules has been drawn out.

[0079] The above steps can be added, removed, modified, or adjusted in order as needed. For example, if the liquid dispensing system 10 has a card reader 125, the card reader 125 can read the information of the medicine box 20, etc.

[0080] Example 2: Example 2 of this utility model provides a liquid addition system 10, which is further improved based on Example 1. The improvement lies in the structure of the spring guide 130. Other parts not mentioned can be referred to Example 1 or the prior art.

[0081] For details, please refer to Figure 12 As shown, the spring guide 130 also includes a guide plate 133 and several guide balls 134. The number of balls can be selected as needed, such as two, five, eight, etc.

[0082] The bottom surface of the guide plate 133 is cylindrical, and its top end is detachably connected to the T-shaped piece 131. The detachable connection method is not limited, such as bolt connection, snap-fit ​​connection, etc.

[0083] The top surface of the guide plate 133 and the bottom surface of the T-shaped piece 131 are attached to each other, and both can be cylindrical surfaces.

[0084] The guide ball 134 can be a steel ball or a spherical object made of other materials. The guide ball 134 is embedded between the guide plate 133 and the T-shaped member 131 with its bottom exposed. The guide ball 134 can roll into contact with the second needle roller 124, reducing the friction between the spring guide member 130 and the second needle roller 124, making the rotation of the second needle roller 124 smoother.

[0085] If there are multiple guide balls 134, some of the guide balls 134 can be distributed circumferentially along the guide plate 133. Since the bottom surface of the guide plate 133 is a cylindrical surface, all the balls on the guide plate 133 can contact the second needle roller 124. The second needle roller 124 can only move up and down and cannot move down.

[0086] The method by which the guide ball 134 is fixed between the guide plate 133 and the T-shaped member 131 is not limited. For example, but not limited to the following scheme, the guide plate 133 is provided with a plurality of guide through holes, the surface of which is part of a sphere, with the upper diameter being larger than the lower diameter and the lower diameter being smaller than the diameter of the guide ball 134. The bottom end of the T-shaped member 131 is provided with a spherical concave hole. The concave hole and the guide through holes roughly form a spherical cavity with one end open. The guide ball 134 is confined within the guide through holes and the concave hole. This arrangement makes the assembly and disassembly of the guide ball 134 and the guide plate 133 more convenient.

[0087] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
