Description

Technical Field

[0001] The present application relates to the field of grinders, and in particular to a tablet grinder for infants and young children. Background Art

[0002] When infants and young children take adult medications, they need to strictly control their dosage, for example, taking only half the amount of an adult tablet or less. Therefore, a tablet grinder is needed to crush a tablet into particles. In addition, when infants and young children refuse to take tablets, they often need to be ground into powder and mixed with food that does not affect the efficacy of the medicine. Therefore, tablet grinders are widely used.

[0003] When currently used grinders grind and crush tablets, the particles after crushing are often too large and the crushing is not thorough. Multiple crushings are required to obtain the powder required for use.

[0004] Patent application number CN202322928872.1 discloses a method for crushing objects using rotating blades. The objects may be tablets, but blade crushing can result in incomplete crushing or significantly increased crushing time due to the distance between the blades and the bottom of the cup. Patent application numbers CN200920290620.8, CN202323103686.0, and CN201020691946.4 all disclose the use of extrusion to grind tablets. However, extrusion alone is difficult to compress tablets into powder, making it difficult to achieve the desired powder quality and maintain the required efficiency and grinding quality.

[0055] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0056] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0057] Refer to the attached Figure 1-21 ,

[0058] A tablet grinder for infants and young children comprises a grinding cup 1, a grinding member 2, a driving member 3, a first extruding member 4, a second extruding member 5 and a connecting member 6.

[0059] The crushing cup 1 has a cup body 11 and a cup cover 12, and the cup body 11 is placed on the base 18. The cup cover 12 and the cup body 11 can be screwed together by means of a threaded connection. The cup body 11 is used to place tablets that need to be crushed. The crushing member 2 and the driving member 3 are both connected to the cup cover 12. The driving member 3 is used to drive the crushing member 2 to rotate so that the crushing member 2 crushes the tablets in the cup body 11, wherein the driving member 3 can be a motor, and the crushing member 2 can be a rotating knife. The rotating knife rotates in the cup body 11 and can crush the tablets in the cup body 11. The crushing member 2 can also have a rod body, and the rotating knife is set on the rod body, so that when the cup cover 12 and the cup body 11 are tightened, the rotating knife is located near the bottom of the cup body 11, which is convenient for cutting and crushing the tablets at the bottom of the cup body 11 into granular fragments.

[0060] The first extrusion member 4 is arranged on the cup cover 12. The first extrusion member 4 has a concave cavity composed of a first guide surface 41, and the concave cavity opens toward the cup body 11. The second extrusion member 5 has a second guide surface 51 and a third guide surface 52, and the first guide surface 41 matches the second guide surface 51. The connecting member 6 is used to make the first extrusion member 4 and the second extrusion member 5 directly or indirectly approach each other and move away from each other. The connecting member 6 can adopt an electric push rod, which directly drives the first extrusion member 4 and the second extrusion member 5 to approach each other and move away from each other. When the connecting member 6 adopts an electric push rod, the connecting member 6 is connected to the cup cover 12, and the connecting member 6 drives the first extrusion member 4 to move closer to and away from the second extrusion member 5. Or the connecting member 6 passes through the first extrusion member 4 and is connected to the second extrusion member 5, and the connecting member 6 drives the second extrusion member 5 to move closer to and away from the first extrusion member 4.

[0061] The first extrusion member 4 and the second extrusion member 5 are both blocks. The first guide surface 41, the second guide surface 51, and the third guide surface 52 can each be a conical surface, a frustum, or other surfaces formed by rotating one or more curved or linear profiles around a fixed axis. Conical surfaces are preferably used. When the first extrusion member 4 and the second extrusion member 5 are separated from each other, space exists between the first guide surface 41 and the second guide surface for accommodating the scrap. When the first extrusion member 4 and the second extrusion member 5 are brought closer together, the first guide surface 41 and the second guide surface 51 compress the scrap and crush it.

[0062] When the upright pulverizing cup 1 is rotated until it is inverted, the crushed materials in the cup body 11 fall directly onto the first guide surface 41, or first fall onto the third guide surface 52 and then flow along the third guide surface 52 to the first guide surface 41. The connecting member 6 brings the first extruding member 4 and the second extruding member 5 closer to each other, so that the first extruding member 4 and the second extruding member 5 squeeze the crushed materials into powder.

[0063] After the crushed material is squeezed into powder, the grinding cup 1 is rotated from an inverted position to an upright position, and then the powder on the first guide surface 41, that is, the powder in the concave cavity, falls directly to the bottom of the cup body 11, or first falls to the opposite guide surface, and flows to the bottom of the cup body 11 along the second guide surface 51, thereby gathering the powder to the bottom of the cup body 11. At this time, the cup cover 12 is opened and removed. Only powder remains in the cup body 11, and the powder can be directly poured out.

[0064] Therefore, in this embodiment, the tablets are cut and crushed first, and then the crushed tablets are crushed to obtain powdered tablets. The operation is carried out in a crushing cup 1, and during operation, it is only necessary to place the crushing cup 1 upright or inverted. The operation is simple, and the effect of crushing the tablets into powder is better and the efficiency is higher.

[0065] In some embodiments, the second extruding member 5 is connected to the crushing member 2, such that the driving member 3 drives the second extruding member 5 to rotate. Specifically, the second extruding member 5 is fixed to the rod of the crushing member 2. When the first extruding member 4 and the second extruding member 5 approach each other, the second extruding member 5 rotates, causing the second guide surface 51 to rotate relative to the first guide surface 41. This embodiment not only extrudes the crushed material, but also utilizes rotation to more thoroughly crush the crushed material into powder.

[0066] In some embodiments, the tablet grinder for infants and young children further includes a drying element 7, which is used to directly or indirectly introduce dry air into the cup body 11. The drying element 7 can be a pump with a drying air function, or a pump connected to an external dry air supply. If the grinding cup 1 is not used for an extended period of time, if the cup lid 12 is forgotten to be tightened, and if the grinding cup 1 is placed in a relatively humid environment, the cup body 11 may become relatively damp. Therefore, before or after use, or at least only before use, dry air can be introduced into the cup body 11 using the drying element 7 to replace the air in the cup body 11, thereby making the air in the cup body 11 relatively dry. This effectively protects the tablets from being reduced in effectiveness due to moisture during grinding. Furthermore, an exhaust port can be provided on the cup lid 12 to allow the moist air in the cup body 11 to be discharged after the dry air is injected into the cup body 11. Alternatively, when the drying element 7 is in use, the cup lid 12 can be opened relative to the cup body 11 to allow the moist air in the cup body 11 to be discharged.

[0067] In some other specific embodiments, the cup cover 12 further has a accommodating cavity 121, and the accommodating cavity 121 is docked with the cup body 11. Since the cup cover 12 can be threadedly connected to the cup body 11, the cup cover 12 partially intersects with the cup body 11, and the accommodating cavity 121 is partially at the intersection. The outer contour trajectory of the first guide surface 41 coincides with the inner wall surface of the accommodating cavity 121, and the outer contour trajectories of the second guide surface 51 and the third guide surface 52 are both separated from the inner wall of the accommodating cavity 121, so that when the crushing cup 1 is inverted, the crushed material can flow along the third guide surface 52 to the concave cavity; and when the crushing cup 1 is upright, the powder can flow along the second guide surface 51 to the cup body 11.

[0068] Specifically, the inner wall of the accommodating chamber 121 has a fourth guide surface 122 and a fifth guide surface 123. In one preferred embodiment, a protrusion with a triangular cross-section is formed on the inner wall of the accommodating chamber 121, and the outer wall of this protrusion forms the fourth guide surface 122 and the fifth guide surface 123. The fourth guide surface 122 is located below the fifth guide surface 123. The projections of the second guide surface 51 and the third guide surface 52 on the first guide surface 41 intersect with the projection of the fourth guide surface 122 on the first guide surface 41 and with the projection of the fifth guide surface 123 on the first guide surface 41. The fourth guide surface 122 guides the crushed material toward the concave cavity; the fifth guide surface 123 guides the powdered material toward the interior of the cup body 11. The fourth guide surface 122 and the fifth guide surface 123 are provided to prevent the powdered material or crushed material from flowing to the position where the first extrusion member 4 abuts the inner wall of the accommodating chamber 121, thereby better preventing material jamming.

[0069] Example 2

[0070] The difference between Example 2 and Example 1 is that:

[0071] The crushing member 2 includes: a rotating body 21 and a crushing knife group 22. The crushing knife group 22 is a plurality of blades. The crushing knife group 22 is connected to the rotating body 21, and the driving member 3 drives the rotating body 21 to rotate, thereby causing the crushing knife group 22 to rotate and cut and crush the tablets in the cup body 11. The rotating body 21 adopts a rod body, preferably a cylindrical rod body. The rotating body 21 passes through the first extrusion member 4, and the first extrusion member 4 can rotate and move relative to the rotating body 21. An exhaust cavity 211 is opened in the rotating body 21, and the exhaust cavity 211 has an exhaust port with the exhaust direction facing the bottom surface and the side surface of the cup body 11. The exhaust port is connected to the exhaust cavity 211, and the exhaust port is also located on the exhaust cavity 211. The drying element 7 is used to discharge the dry air into the exhaust cavity 211, so that the dry air will be discharged toward the bottom of the cup body 11 and the side wall of the cup body 11. In Example 1, the crushing element 2 is close to the bottom of the cup body 11, so it is not only convenient to crush the tablets, but also convenient for the dry gas to quickly fill the entire cup body 11.

[0072] In some embodiments, the first extrusion member 4 and / or the second extrusion member 5 both have a cavity. The cavity of the first extrusion member 4 and / or the cavity of the second extrusion member 5 are directly or indirectly connected to the exhaust cavity 211. The first extrusion member 4 and the second extrusion member 5 are both thermally conductive. The cavity is provided so that the drying gas from the drying member 7 first enters the cavity and, after sufficient heat conduction with the first extrusion member 4 and the second extrusion member 5, the temperature of the first extrusion member 4 and the second extrusion member 5 is the same as the temperature of the dry air in the cup body 11, so that the tablets are crushed and extruded at the same temperature, thereby better ensuring the quality of the tablets extruded into powder.

[0073] In addition, in the solution where the connecting member 6 moves the first extrusion 4 closer to and away from the second extrusion 5, the second extrusion 5 has a cavity. In the solution where the second extrusion 5 moves closer to and away from the first extrusion 4, the first extrusion 4 has a cavity.

[0074] In some other embodiments, the first guide surface 41 has different inclination angles at different locations, and the inclination angle gradually decreases as the first guide surface 41 approaches the rotating body 21. This makes it difficult for the crushed materials on the first guide surface 41 to be thrown outward due to the centrifugal force generated by the relative rotation of the second extrusion member 5 and the first extrusion member 4.

[0075] Example 3

[0076] The difference between Example 3 and Example 1 and Example 2 is that:

[0077] The drying unit 7 includes a first filter element 71 , a second filter element, a pneumatic pump body 73 and a heating element.

[0078] The pneumatic pump body 73 allows external air to pass through the first filter component 71, the second filter component and the heating component in sequence, and then pass through the exhaust cavity 211 to enter the cup body 11. The pneumatic pump body 73 adopts existing technology. Among them, the first filter component 71 filters solid particles, and the second filter component filters water vapor in the external air. The first filter component 71 adopts a filter mesh, and the second filter component adopts a desiccant. Alternatively, the first filter component 71 adopts a block with a drying chamber, and a filter hole 74 is formed on the first filter component 71, so that the air leaves the first filter component 71 after passing through the filter hole 74 and the desiccant, that is, leaves the first filter component 71 and the second filter component. Among them, the second filter component adopts a desiccant, specifically the second filter component adopts a mesh bag filled with a desiccant. The first filter component 71 is fixed to the second filter component, and the second filter component is placed in the drying chamber to achieve the fixation of the first filter component 71 and the second filter component. The cup cover 12 has a first mounting chamber 13 and a second mounting chamber 14 that are interconnected, and the pneumatic pump body 73 and the heating component are arranged in the first mounting chamber 13. The second mounting chamber 14 is an opening that is connected to the first mounting chamber 13, and the first filter component 71 and the second filter component are detachably arranged in the second mounting chamber 14.

[0079] In a specific embodiment, the cup cover 12 includes a recess 15 and a cover plate 16. The recess 15 forms the first mounting chamber 13, and the cover plate 16 forms the second mounting chamber 14. The cover plate 16 is fixed to the recess 15. The pneumatic pump body 73 and the heating element are both mounted in the recess 15. A sealing plate 17 is also provided on the cover plate 16, which also has a slide groove. The sealing plate 17 is slidably connected to the slide groove. The sealing plate 17 can then slide on the cover plate 16 to block the second mounting chamber 14, thereby preventing the desiccant from becoming ineffective due to moisture when not in use. The first filter element 71 and the second filter element are detachably connected to the second mounting chamber 14 via magnetic attraction. When the first filter element 71 is installed in the second mounting chamber 14, the filter holes on the first filter element 71 can contact the sealing plate 17. A soft pad is provided on the sealing plate 17. When the sealing plate 17 slides, the soft pad on the sealing plate 17 can clean the filter holes on the first filter element 71.

[0080] In a specific solution, the driving member 3 adopts a combination of a motor and a transmission belt, or a combination of a motor and a transmission gear. The motor is arranged in the second installation chamber 14. A rotary joint is provided at the end of the rotating body 21, one end of the rotary joint is fixed to the rotating body 21, and a connecting box 76 is provided at the other end. The rotary joint is connected to the connecting box 76 through a pipeline or directly, and a heating element is provided in the connecting box 76. A conical tube 75 is provided at the second installation chamber 14, one end of the pneumatic pump body 73 is connected to the conical tube 75, and the other end is connected to the connecting box 76, so that the external air enters the exhaust cavity 211 through the first filter structure, the second filter structure, and the heating element in sequence. The connecting box 76 is a heat-insulating material, and the connection box 76 is provided to prevent the heating element from causing the temperature of the first installation chamber 13 to rise, thereby affecting the performance of the pneumatic pump body 73.

[0081] In another embodiment of the first filter component 71 and the second filter component, the first filter component 71 includes two docking shells 711, which are docked together to form a block having a drying chamber. Filter holes are formed on both docking shells 711. A filter housing 72 is also included, and the filter housing 72 can be detachably connected to either of the two docking shells 711 by interference fit. When the first filter component 71 is installed in the second installation chamber 14, the filter housing 72 and the two docking shells 711 are arranged in the direction away from the cup body 11. Therefore, when the filter hole cup on the docking shell 711 is clogged with dust, the first filter component 71 can be taken out, then flipped over, and the filter housing 72 can be connected to the other docking shell 711 and reinstalled in the second installation chamber 14. This facilitates self-cleaning of dust on the docking shell 711.

[0082] Example 4

[0083] The difference between Example 4 and Example 1, Example 2 and Example 3 is that:

[0084] The connecting member 6 includes: a moving body 61, an elastic body 62 and a guide body. The moving body 61 adopts a threaded rod 611, and the threaded rod 611 is threadedly connected to the cover plate 16. The moving body 61 moves to at least a first moving position and a second moving position relative to the cup cover 12, and the elastic body 62 is used to directly or indirectly connect the moving body 61 to the first extrusion member 4. The guide body is used to guide the first extrusion member 4 along the direction in which the first extrusion member 4 and the second extrusion member 5 approach each other and move away from each other. When the moving body 61 moves to the first moving position, the first extrusion member 4 moves away from the second extrusion member 5; when the moving body 61 moves to the second moving position, the first extrusion member 4 approaches the second extrusion member 5 until the first guide surface 41 is pressed against the second guide surface 51, and the elastic body 62 is in a compressed state. The elastomer 62 is in a compressed state, which can make the first extrusion piece 4 be subjected to an elastic force to move closer to the second extrusion piece 5. Then, when the first extrusion piece 4 contacts the second extrusion piece 5, the crushed materials may not be completely extruded into powder. Therefore, there is a gap between the first extrusion piece 4 and the second extrusion piece 5. However, with the relative rotation of the first extrusion piece 4 and the second extrusion piece 5, the crushed materials can be gradually completely extruded into powder. The elastomer 62 is in a compressed state, which can make the first extrusion piece 4 move closer to the second extrusion piece 5 in the process of the crushed materials gradually turning into powder.

[0085] In a specific embodiment, the guide body can be a portion of the rotating body 21, with the rotating body 21 extending through the first extruded member 4. The hole in the first extruded member 4 is completely aligned with the rotating body 21, thereby guiding the movement of the first extruded member 4. Alternatively, the guide body can be a linear bearing disposed in the hole in the first extruded member 4, and the linear bearing and the rotating body 21 cooperate to guide the first extruded member 4. Alternatively, the cup cover 12 further includes a receiving chamber 121, the guide body receiving the inner wall surface of the chamber 121, and the first extruded member 4 abuts against the inner wall surface of the chamber 121.

[0086] In a specific solution, the elastic body 62 is a spring; or an elastic pad; or an elastic metal sheet.

[0087] Among them, the movable body 61 includes a threaded rod 611 and a combining rod 612, the combining rod 612 is fixed to the first extrusion member 4, and the threaded rod 611 is threadedly connected to the cover plate 16. The threaded rod 611 and the combining rod 612 are limitedly connected, and an elastomer 62 is arranged between the threaded rod 611 and the combining rod 612. The limited connection means that when the threaded rod 611 moves away from the cup body 11, it drives the combining rod 612 to move away from the cup body 11. The threaded rod 611 and the combining rod 612 can be connected by a rope 63. Alternatively, a limiting structure is used to connect the threaded rod 611 and the combining rod 612, which will not be elaborated in detail. An abutment portion is provided on the threaded rod 611, and an abutment portion is also provided on the combining rod 612. The elastomer 62 adopts a spring and is located between the two abutment portions.

[0088] Example 5

[0089] The difference between Example 5 and Example 1 is that:

[0090] The cup body 11 includes a medicine cutting cavity 91, and the cup lid 12 includes a cutter 81. When the cup lid 12 is secured to the cup body 11, the cutter 81 moves into the medicine cutting cavity 91 and abuts against the bottom surface of the cavity 91. Therefore, the pulverizing cup 1 of the present application also functions to cut tablets. This allows the pulverizing cup 1 to cut tablets into pieces while an infant is taking adult medication, providing a more comprehensive function.

[0091] Among them, a first tube 8 is provided on the accommodating chamber 121, and a second tube 9 is provided in the cup body 11. When the cup cover 12 is fixed to the cup body 11, the first tube 8 and the second tube 9 are docked and pressed tightly. By setting scale lines on the outside of the cup cover 12 and the cup body 11, when the scale lines of the cup cover 12 and the cup body 11 coincide, the cup cover 12 and the cup body 11 are tightened, and the first tube 8 and the second tube 9 are pressed tightly and sealed. The cutter 81 is provided at the first tube 8, and the medicine cutting cavity 91 is provided in the second tube 9. The bottom surface of the medicine cutting cavity 91 has a avoidance groove for the cutter 81 to cut into. When the first tube 8 and the second tube 9 are pressed tightly, the outer wall portion of the first tube 8 abuts against the inner wall of the second tube 9, thereby increasing the sealing between the first tube 8 and the second tube 9.

[0092] In addition, in order to better connect and seal the first tube 8 and the second tube 9, it is necessary to move the first tube 8 and the second tube 9 closer to each other. For this purpose, the cup cover 12 and the cup body 11 can be directly plugged together using interference fit.

[0093] In some other embodiments, in order to make the threaded rod 611 rotate more easily, a motor may be provided at the threaded rod 611 to drive the threaded rod 611 to rotate.

[0094] Alternatively, a larger block may be provided on the threaded rod 611 to facilitate rotation by external force. In this embodiment, the larger block is a circular block. In this embodiment, a cushion is provided on the circular block, replacing the sealing plate 17. The circular block rotates until the cushion blocks the second mounting chamber 14, replacing the sealing plate 17.

[0095] The circular block has a through slot with a keyway in it. The threaded rod 611, which forms the optical axis, passes through the through slot, and the end of the threaded rod 611 forms a stopper plate that contacts the circular block. A flat key is provided on the threaded rod 611, which slides into the keyway. The flat key can be replaced by a spline or sliding key.
