[0011] In view of this, the present invention provides an upgraded and improved multifunctional medicine grinding device to solve the problems of not only preventing medicine from splashing during the grinding process, but also adjusting the angle to grind coarse particles into fine particles, while facilitating the pouring of medicine without additional manual intervention.

[0012] This application provides an upgraded and improved multifunctional pharmaceutical grinding device, including a housing, grinding components, a storage component, and a control component;

[0013] The casing includes a front casing and a rear casing that are perpendicular to each other, and the front casing and the rear casing form a hollow structure in the shape of a figure 7.

[0014] The grinding assembly includes a hollow frustum-shaped mortar and a pestle that matches the mortar. The mortar includes a parallel upper bottom surface and a lower bottom surface. The upper bottom surface has an opening and is located near the front of the housing. The pestle includes a hemispherical pestle head and a pestle rod that is fixedly connected to the pestle head. The pestle rod is T-shaped. A circular filter hole is provided on the lower bottom surface. The filter hole extends through the lower bottom surface from the upper bottom surface to the lower bottom surface. A stirring protrusion is provided on the lower bottom surface near the upper bottom surface.

[0015] The storage assembly includes a pad and a bracket. The bracket is located on the side of the pad near the rear of the housing. The pad includes a parallel upper pad and a lower pad, both of which are rectangular. The two apex corners of the upper and lower pads, away from the rear of the housing, are respectively connected to a left front rod and a right front rod, which are also rectangular rods. The upper pad, lower pad, left front rod, right front rod, and part of the bracket constitute a rectangular frame structure. The orthographic projection of the front of the housing is located within the orthographic projection of the rectangular frame structure along the direction from the upper bottom surface to the lower bottom surface.

[0016] The side of the upper pad away from the lower pad contacts the bottom surface. The upper pad has two semi-circular upper pad through holes and one upper pad through groove. The orthographic projection of the upper pad through hole and the orthographic projection of the filter hole completely overlap along the direction from the upper bottom surface to the lower bottom surface. The diameter sides of the two upper pad through holes are parallel and close to each other but not connected. The upper pad through groove is located at the perpendicular point connecting the centers of the two upper pad through holes. Along the direction from the rear of the housing to the left front rod, the length extension direction of the upper pad through groove is in the shape of a "7". The other end of the upper pad through groove opens through the geometric center of the side of the upper pad closest to the bracket.

[0017] The rectangular frame structure contains a pull-out box, which is a rectangular box with an opening. The pull-out box is pulled out along the rear of the machine housing in the direction of the left front rod, and the opening of the rectangular box faces the mortar side. Along the direction from the top bottom surface to the bottom bottom surface, the orthographic projection of the through hole of the upper pad plate is located within the orthographic projection of the rectangular box.

[0018] The support includes a frame plate and a support ring. The frame plate is a rectangular plate extending from the upper bottom surface to the lower bottom surface. The support ring is a hollow ring body. The mortar is placed in the hollow ring body. The support ring is slidably connected to the side of the frame plate away from the rear of the machine housing. The two apex corners of the upper pad plate and the lower pad plate near the rear of the machine housing are connected to the side of the frame plate away from the rear of the machine housing.

[0019] The control components include a power plug, a controller, an input panel, a motor, a control lever, an upper transmission component, a middle transmission component, and a lower transmission component. The control lever is a turbine rod extending from the upper bottom surface to the lower bottom surface. The two ends of the turbine rod are connected to the front and rear of the housing, respectively. The power plug is located through the rear of the housing on the side away from the frame plate. The input panel is fixed on the front of the housing on the side away from the upper pad plate. The controller and motor are fixedly connected to the rear of the housing. The power plug, controller, input panel, and motor are electrically connected. The upper, middle, and lower transmission components are sequentially sleeved on the turbine rod. The motor is rotatably connected to the turbine rod, the turbine rod to the upper transmission component, the turbine rod to the middle transmission component, and the turbine rod to the lower transmission component. The upper transmission component drives the pestle to move up and down in the direction from the upper bottom surface to the lower bottom surface. The middle transmission component drives the pestle to move in its circumferential direction. The lower transmission component drives the stirring cam to rotate in the circumferential direction of the pestle.

[0020] Compared with the prior art, the upgraded and improved multifunctional pharmaceutical grinding equipment provided by the present invention achieves at least the following beneficial effects:

[0021] First, the upgraded and improved multifunctional medicine grinding device provided by this invention can effectively solve the problem of drug splashing. For example, this invention controls the rotation of the mortar and pestle through a central transmission component, fundamentally avoiding drug splashing. Furthermore, this invention provides a hollow frustum-shaped mortar, which is placed to reduce the amount of drug splashed out of the mortar. In addition, this invention reinforces the mortar with a support ring to prevent drug splashing caused by instability of the mortar.

[0022] Secondly, the upgraded and improved multifunctional medicine grinding equipment provided by this invention can perform fine grinding with good overall particle size alignment. Firstly, the upper transmission component controls the pestle to hammer the Chinese medicine vertically, while the middle transmission component controls the pestle to apply circumferential grinding pressure to the medicine, ensuring the medicine is ground circumferentially within the mortar. Simultaneously, the stirring convex plate improves the tumbling efficiency of the medicine, allowing larger particles to float to the surface and be ground by the pestle. Furthermore, the filter provided by this invention can screen qualified powder, allowing medicines that do not meet the size requirements to continue grinding in the mortar until they are ground into particles that can pass through the filter.

[0023] Third, the upgraded and improved multifunctional medicine grinding equipment provided by this invention can automatically grind and crush medicine without additional manual intervention. First, the invention has through holes in the upper pad plate so that the medicine powder filtered by the filter holes can pass through the upper pad plate. Then, a pull-out box is set between the upper and lower pad plates, which can automatically pick up the medicine powder. Furthermore, the pad frame is a hollow rectangular structure, and the pull-out box can be pulled away from the side of the frame plate to realize the automatic acquisition of medicine powder.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time.

In this embodiment, the upper transmission component 4 controls the pestle 222 to hammer the Chinese medicine in the vertical direction, and the middle transmission component 47 controls the pestle 22 to apply circumferential grinding pressure to the Chinese medicine, so that the Chinese medicine is ground in the circumferential direction within the mortar 21. At the same time, the stirring convex plate 23 in this embodiment can improve the turning efficiency of the Chinese medicine, so that larger particles of Chinese medicine can easily float to the surface and be ground by the pestle 22. In addition, the filter hole 211 provided in this embodiment can screen qualified powder, so that Chinese medicine that does not meet the size requirement can continue to be ground in the mortar 21 until it is ground into particles that can pass through the filter hole 211.

[0077] Third, the upgraded and improved multifunctional medicine grinding equipment provided in this embodiment can automatically grind and crush medicine without additional manual intervention.

The projections of the upper cam 462, the control cam 464, and the upper transmission belt 465 do not overlap in the direction Z from the upper bottom surface to the lower bottom surface 212. The upper cam 462, the control cam 464, and the upper transmission belt 465 are connected by the upper cam 462 to form an intermittent drive mechanism, which causes the upper cam 462 to intermittently control the pestle 22 to perform up and down hammering in the direction Z from the upper bottom surface to the lower bottom surface 212.

The outer wall of the spline 482 can be fitted and fastened with the spline sleeve 24. The perpendicular bisector of the spline 482 coincides with the perpendicular bisector of the pestle 222. When the lower traction member drives the spline 482 to rotate, the spline sleeve 24 and the stirring protrusion 23 connected thereto can rotate.

[0096] The pestle 222 includes a rectangular horizontal plate 2221 and a vertical rod 2222 connected to the horizontal plate 2221. The vertical rod 2222 is cylindrical. The horizontal plate 2221 and the vertical rod 2222 form a T-shaped structure. The side of the horizontal plate 2221 away from the vertical rod 2222 is in contact with the upper cam 462, and the side of the vertical rod 2222 away from the horizontal plate 2221 is fixedly connected to the pestle head 221.

[0097] Specifically, the side of the pestle head 221 away from the pestle handle 222 that contacts the inner wall of the mortar 21 is an arc-shaped surface. The specific shape of the pestle head 221 can be hemispherical. The arc-shaped surface of the pestle head 221 is used to contact the Chinese medicine and to pound or grind the Chinese medicine.

[0098] The horizontal plate 2221 is a plate-like structure, and its top view projection along the direction Z from the upper bottom surface to the lower bottom surface 212 is rectangular. The vertical rod 2222 is a solid round rod, and one end of the vertical rod 2222 along its length direction is perpendicularly connected to the geometric center of one side of the horizontal plate 2221 by welding; along the direction Z from the upper bottom surface to the lower bottom surface 212, the top view projection of the vertical rod 2222 coincides with the top view projection of the horizontal plate 2221; along the rear body 12 of the housing pointing to the left front rod 314X, the side view projection of the horizontal plate 2221 and the vertical rod 2222 is T-shaped; the perpendicular bisector of the horizontal plate 2221 coincides with the central axis of the vertical rod 2222.

[0099] Through the aforementioned arc-shaped surface, the pestle 221 can automatically adjust the angle of contact with the Chinese medicine being ground according to its shape, so that during the grinding process, the pestle 221 can better fit the sample surface and increase the effective contact area. The arc-shaped surface design allows the pressure of the pestle 221 to be more evenly distributed on the contact surface, avoiding excessive local pressure and thus reducing damage to the pestle 221. Furthermore, the horizontal plate 2221 can increase the contact area between the vertical rod 2222 and the upper cam 462, making it easier for the upper cam 462 to control the vertical rod 2222 to hammer the Chinese medicine.

[0100] In an alternative embodiment, continue to refer to Figure 2 As shown, a cross coupling is fixedly welded to the side of the vertical rod 2222 away from the horizontal plate 2221, and the pivot of the cross coupling is parallel to the upper pad 311.

[0101] Specifically, the cross coupling is a connector made of rubber and metal composite; the side of the pestle head 221 away from the arc surface and the end of the pestle rod 222 away from the upper cam 462 are respectively fixedly connected to the two shaft ends of the cross coupling by welding; the cross pivot of the cross coupling is parallel to the upper pad 311.

[0102] The aforementioned cross coupling is a technology known to those skilled in the art and is not an improvement point. It does not need to be described in detail. Those skilled in the art can understand the specific structure and how to implement it based on the position and overall structure of this solution.

[0103] The above scheme enables greater cross-compensation between the pestle head 221 and the pestle rod 222, allowing the pestle head 221 to rotate and grind effectively within the mortar 21. Furthermore, it makes the structure between the pestle head 221 and the pestle rod 222 more compact and reasonable, increasing the reaction bearing capacity of the pestle head 221 during grinding. It also enables the transmission efficiency between the pestle head 221 and the pestle rod 222 to reach 98-99.8%, resulting in excellent grinding effect.

[0104] In an alternative embodiment, reference continues... Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the support ring 322 includes a fixed ring 3222 and a fixed block 3221 connected to the fixed ring 3222. The fixed ring 3222 is a circular ring, which is parallel to the upper pad 311. The fixed block 3221 has an I-shaped structure. The mortar 21 is placed inside the circular ring. The fixed block 3221 is slidably connected to the frame plate 321 on the side away from the circular ring.

[0105] Specifically, the fixing ring 3222 is a circular ring, and any cross-section of it perpendicular to the circumference can be circular or rectangular; the material of the fixing ring 3222 can be metal, specifically stainless steel, which has high strength, rigidity, and corrosion resistance; the inner diameter of the fixing ring 3222 is larger than the opening diameter of the mortar 21 and smaller than the bottom diameter of the mortar 21; the fixing ring 3222 can be fitted onto the outer wall of the mortar 21 to fix the mortar body; a fixing block 3221 is fixedly connected to the outer side of the fixing ring 3222 away from the mortar 21, and the connection method can be welding; the fixing ring 3222 can be fixed to the frame plate 321 through the fixing block 3221 and can move on the frame plate 321.

[0106] Through the above embodiments, the side wall of the mortar 21 away from its bottom can be sleeved and fixed during the process of pounding Chinese medicine, so that the mortar 21 can maintain the stability of the mortar body, enhance the operational stability during the grinding process, and enhance the grinding efficiency.

[0107] In an alternative embodiment, continue to refer to Figure 2 , Figure 6 and Figure 7 As shown, the side of the frame plate 321 away from the rear body 12 of the housing is provided with a frame plate groove 3211 that matches the I-shaped structure. The mid-section of the frame plate groove 3211 perpendicular to its length direction is convex. The frame plate groove 3211 extends along the length direction of the frame plate 321, and the I-shaped structure is slidably connected in the frame plate groove 3211.

[0108] Specifically, the frame plate 321 and the support ring 322 are slidably connected; the side of the frame plate 321 away from the rear body 12 of the housing is provided with a frame plate protrusion 3211 extending along the length direction of the frame plate 321. The frame plate protrusion 3211 is a straight groove, and the mid-section of the frame plate protrusion 3211 perpendicular to its length extension direction is convex; the opening of the frame plate protrusion 3211 faces the direction of the mortar 21; the length of the frame plate protrusion 3211 is less than the length of the frame plate 321.

[0109] The fixing block 3221 has an I-beam structure. The frame plate 321 and the fixing ring 3222 are respectively disposed on opposite sides of the fixing block 3221. The fixing block 3221 slides within the frame plate protrusion 3211 of the frame plate 321. The fixing block 3221 includes a connecting part and a first rectangular part and a second rectangular part vertically connected to both ends of the connecting part. The first rectangular part, the connecting part and the second rectangular part form an I-beam structure. Both the first rectangular part and the second rectangular part are rectangular blocks. The first rectangular part on the fixing block 3221 is disposed within the frame plate protrusion 3211. The side of the second rectangular part on the fixing block 3221 away from the first rectangular part is welded to the fixing ring 3222. The middle parts of the first rectangular part and the second connecting part on the fixing block 3221 are respectively connected to both ends of the connecting part along its length extension direction. The connecting part can be a rectangular block or a cylinder. In this embodiment, a rectangular block is used as an example. The connecting part extends through the frame plate protrusion 3211 to the outside of the frame plate 321 away from the rear body 12 of the housing. The length of the connecting part is greater than the depth of the frame plate protrusion 3211.

[0110] The above scheme enables relative movement between the fixing ring 3222 and the support plate 321, thereby facilitating the adjustment of the position of the mortar 21. Sliding the fixing block 3221 and the fixing ring 3222 away from the lower pad 312 allows the fixing ring 3222 to be removed from the outer wall of the mortar 21, thereby allowing the mortar 21 to be removed from the upper pad 311. Furthermore, the stability and load-bearing capacity of the fixing ring 3222 can be improved by increasing the width of the support plate groove 3211 and the material strength of the fixing block 3221.

[0111] In an alternative embodiment, reference continues... Figure 2 , Figure 4 and Figure 8 As shown, the stirring cam 23 is a double-rounded rectangular piece. A cam is provided in the middle of the stirring cam 23. The cam protrudes 231 away from the bottom surface 212. The stirring cam 23 has two long sides, which are serrated edges 232.

[0112] Specifically, the stirring protrusion 23 is specifically disposed on the side of the lower bottom surface 212 of the mortar 21 near its upper bottom surface. The vertical line of the stirring protrusion 23 along its length coincides with the vertical line of the bottom of the mortar 21. The stirring protrusion 23 is a double-rounded rectangular piece. The arc shape of the end of the stirring protrusion 23 coincides with the circumferential outline of the lower bottom surface 212 of the mortar 21. The length of the stirring protrusion 23 is the same as the diameter of the lower bottom surface 212 of the mortar 21. A protrusion 231 is provided in the middle of the stirring protrusion 23. The length extension direction of the protrusion 231 is the same as the length extension direction of the stirring protrusion 23. The height of the protrusion 231 is not greater than 10mm. The two sides of the stirring protrusion 23 along its length extension direction are serrated edges 232. At least three serrations are provided on each side of the stirring protrusion 23 along its length extension direction. The shape of the serrations can be rectangular blocks or triangular blocks. In this embodiment, the serrations are triangular blocks with the tooth tips facing the side wall of the mortar 21.

[0113] The above scheme allows for the stirring of the Chinese medicine inside the mortar 21, thereby increasing grinding efficiency. First, the stirring protrusions 23 with serrated edges 232 can generate stronger shearing force, effectively breaking down the Chinese medicine and making it more evenly dispersed. Furthermore, when processing materials containing micro or ultrafine powder, the serrated blades 23 with serrated edges 232 can effectively break up agglomerates, improve the dispersibility of fine particles, and thus improve mixing efficiency. The protrusions 231 can reduce the stirring radius, thereby reducing operating resistance, reducing energy consumption, and effectively improving the stirring effect.

[0114] In an alternative embodiment, continue to refer to Figure 2 As shown, the mortar 21 and pestle 221 are made of transparent materials, such as bulletproof glass or artificial agate.

[0115] Artificial agate is generally more transparent than natural agate, as transparent as a glass ball. Through the above methods, artificial agate has higher hardness and better wear resistance. Bulletproof glass is made of glass (or plexiglass) and high-quality engineering plastics (such as polycarbonate fiber) through special processing. It has light transmission and a smooth surface, and at the same time has strong impact resistance.

[0116] The above method makes the inner wall of the mortar 21 and the pestle 221 smooth and frictionless, which can reduce sample residue and avoid cross-contamination; it has high transparency, making it easy to observe the grinding process and suitable for grinding that requires real-time monitoring of the grinding status; it has high chemical stability, strong environmental adaptability, and is not easily affected by external factors.

[0117] Example 2

[0118] This embodiment is an extension of embodiment 1, and will continue to be referred to... Figure 2 , Figure 3 and Figure 9As shown, this embodiment also includes a cleaning component 5, which includes a pressure pump 51, a water supply pipe, a water delivery pipe 52, and a nozzle 53.

[0119] Both the water supply pipe and the water delivery pipe 52 are circular flexible hoses. The water supply pipe passes through the rear body 12 of the machine housing away from the support plate 321. The two ends of the water supply pipe are fixedly connected to the inlet of the pressure pump 51 and the side of the rear body 12 of the machine housing away from the support 32, respectively. The pressure pump 51 is fixedly connected to the lower bottom surface inside the rear body 12 of the machine housing and is electrically connected to the controller 42. The water delivery pipe 52 passes through the rear body 12 of the machine housing and the support plate 321 in sequence. The two ends of the water delivery pipe 52 are fixedly connected to the outlet of the pressure pump 51 and the nozzle 53, respectively. The nozzle 53 is fixed to the end of the pestle 222 near the pestle head 221.

[0120] Specifically, the pressure pump 51 is located at the end of the rear body 12 of the housing away from the front body 11 of the housing. The pressure pump 51 can be the TL-A series of Dopler pumps. The pressure pump 51 is electrically connected to the controller 42 and is controlled by the controller 42. The connection circuit between the pressure pump 51 and the controller 42 is a well-known technology to those skilled in the art and is not an improvement point, so it does not need to be described in detail. Along the direction Z from the upper bottom surface to the lower bottom surface 212, the projections of the pressure pump 51, the motor 44 and the controller 42 do not overlap. The pressure pump 51 is used to increase the water pressure. A water supply hole is provided on the side of the rear body 12 away from the frame plate 321. The two ends of the water supply pipe are respectively connected to the water supply hole of the rear body 12 of the housing and the water inlet of the pressure pump 51. The water supply hole of the rear body 12 of the housing is also connected to the external water supply pipeline. Both the water supply pipe and the water delivery pipe 52 are plastic pipes, and the inner diameter of the water delivery pipe 52 is no more than 5mm.

[0121] A first water inlet is provided on the side of the rear body 12 of the housing near the frame plate 321. A second water inlet is provided on the frame plate 321 corresponding to the position of the first water inlet. The projections of the first water inlet and the second water inlet are superimposed on each other along the rear body 12 towards the left front rod 314X. The other end of the water pipe 52 passes through the first water inlet and the second water inlet in sequence and is connected to the nozzle 53 outside the rear body 12 of the housing.

[0122] The nozzle 53 is a convex sleeve with a through hole extending along its length. The cross-section of the through hole through its central axis is U-shaped. The nozzle 53 is movably fitted onto the outer wall of the pestle 22 through the through hole, specifically at the connection between the pestle rod 222 and the pestle head 221. A hollow, sealed cavity exists between the through hole and the outer shell of the nozzle 53. One end of the water supply pipe 52 is connected to this sealed cavity. The outer shell of the nozzle 53 has a spray nozzle. The nozzle 53 can be fixed and raised / lowered using the pestle 22.

[0123] Furthermore, a drainage hole 303 is provided at one end of the lower pad 312 near the frame plate 321, which penetrates the lower pad 312. The drainage hole 303 is circular in shape, and its diameter is larger than the bottom diameter of the mortar 21. Water sprayed into the mortar 21 by the nozzle 53 can flow into the wastewater collection device of the lower pad 312 through the filter hole 211, the upper pad through hole 301, and the drainage hole 303.

[0124] The above method can clean the residual Chinese medicine from the previous grinding, and the pressurized water can clean more thoroughly, effectively preventing cross-contamination between different Chinese medicines. Furthermore, the cleaning does not require manual operation. The pressurized pump 51 is electrically connected to the controller 42 and is controlled by the controller 42. The filter hole 211, the upper pad through hole 301 and the drainage through hole 303 can quickly discharge the sewage in the mortar 21, making the mortar 21 easier to dry and greatly saving manual operation steps.

[0125] The technical features of this invention are mutually complementary and functionally supportive of each other. In other words, the technical solution is not a “simple superposition” of technical features among multiple prior art documents. Therefore, this invention does not fall under the category of “simple superposition” in Chapter 4 of Part II of the Patent Examination Guidelines.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
