Description

Technical Field

[0001] This invention belongs to the field of biological experimental equipment technology, specifically a portable cell and tissue pulverizer based on an improved structure of a kitchen garlic press. Background Technology

[0002] In modern scientific research and experimental fields, sample pretreatment, as the starting point of the experimental process, plays a decisive role in the accuracy and reliability of subsequent research results, especially in disciplines such as life sciences, medical research, and materials science. The pulverization of tissue samples is a key step in obtaining target substances and analyzing sample characteristics.

[0003] Existing laboratory tissue pulverizing equipment suffers from problems such as large size, high price, and complex operation. Traditional grinding methods are inefficient, and while kitchen garlic grinders have a simple structure, they lack sterile conditions and cannot be used directly in experiments. These problems severely restrict the efficiency and accuracy of experiments. Furthermore, traditional material collection devices often use simple container receiving methods and lack screening functions, which leads to the need for additional screening operations during subsequent use.

[0004] To address these issues, we provide a manual rapid tissue shredder. Utility Model Content

[0005] The purpose of this invention is to provide a manual rapid tissue pulverizer, which solves the problems of large size, high price, complex operation, and lack of screening function in the existing tissue pulverizing equipment by combining the pulverizing component and the collection component.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a manual rapid tissue grinder, comprising a grinding shell, a grinding assembly rotatably connected to the inner cavity of the grinding shell, and a collecting assembly movably connected to the bottom of the grinding shell. The grinding assembly includes a rotating rod, with blades movably connected to the surface of the rotating rod. A coil is fixedly connected to the top of the rotating rod, and the top of the coil is movably connected to the grinding shell. A steel wire is wound around the surface of the coil, with one end of the steel wire extending to the top of the grinding shell and fixedly connected to a pull ring. The surface of the pull ring is slidably connected to the grinding shell. The collecting assembly includes a housing, with both sides of the top of the housing slidably connected to the grinding shell. A collecting box is slidably connected to the inner cavity of the housing, and a filter plate is provided on the top of the collecting box, with one side of the filter plate fixed to the housing. The filter plate has filter holes on its surface and multiple blades, enabling more intensive cutting and grinding of materials, significantly reducing pulverization time and quickly crushing large pieces of material into fine particles. It is particularly suitable for processing large batches of samples or hard materials, effectively improving the processing efficiency of experiments and production. The steel wire, blades, and wire spool are all made of medical-grade stainless steel, which has excellent high-temperature resistance and corrosion resistance. It can withstand commonly used laboratory sterilization methods such as high-temperature and high-pressure sterilization, ultraviolet irradiation, or chemical reagent disinfection, avoiding the presence of bacteria and impurities due to the material's inability to withstand sterilization. The pulverizing shell is made of transparent polycarbonate material, allowing staff to directly observe the pulverization process from the outside.

[0008] The present invention is further configured such that a limiting sleeve is slidably connected to the surface of the steel wire, one side of the limiting sleeve is fixedly connected to the crushing shell, and one end of the limiting sleeve extends to the top of the inner cavity of the crushing shell, providing precise guidance and limiting for the steel wire.

[0009] The present invention is further configured such that a limiting groove is provided on the top of the wire spool, and a limiting disk is slidably connected to the inner cavity of the limiting groove. One side of the limiting disk is fixedly connected to the crushing shell. The sliding cooperation between the limiting groove and the limiting disk provides precise guidance for the rotation of the wire spool and avoids axial displacement or shaking of the wire spool when the steel wire is pulled.

[0010] The present invention is further configured such that sliding grooves are provided on both sides of the inner cavity of the housing, and a slider is slidably connected to the inner cavity of the sliding groove. One side of the slider is fixedly connected to the collection box. There are two sliding grooves and two sliders, so that the collection box can be completely pulled out of the housing for subsequent cleaning or replacement.

[0011] The present invention is further configured such that a limiting ring is rotatably connected to the bottom of the rotating rod, and the bottom of the limiting ring is fixedly connected to the filter plate. The setting of the limiting ring can improve the stability of the rotating rod when it rotates.

[0012] The present invention is further configured such that a mounting plate is fixedly connected to the surface of the rotating rod, and the other side of the mounting plate is connected to the blade by bolts. When the blade is worn or damaged, or when a specific type of blade needs to be replaced due to processing different samples, the blade can be quickly replaced simply by unscrewing the bolts with conventional tools.

[0013] The present invention is further configured such that a positioning groove is provided at the bottom of the mounting plate, and one side of the blade is slidably connected to the positioning groove. The positioning groove provides precise guidance and limitation for the installation of the blade, so that the blade can be accurately positioned during installation and avoid uneven cutting caused by position deviation.

[0014] The present invention is further configured such that rotating plates are rotatably connected to both sides of the top of the shell, and a magnetic card block is fixedly connected to one side of the top of the rotating plate. Card slots are opened on both sides of the crushing shell, and one side of the magnetic card block is engaged with the card slot. A magnetic suction block is provided on one side of the magnetic card block, and the other side of the magnetic suction block is fixedly connected to the crushing shell. The engagement of the magnetic card block with the card slot, combined with the magnetic attraction of the magnetic suction block, forms a double fixing effect. During the crushing operation, even if the equipment vibrates violently, it can ensure that the shell and the crushing shell are tightly connected, preventing sample leakage or equipment damage due to loose connection.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model's pulverizing component replaces large components such as motors with a manual transmission structure consisting of a rotating rod, coil, steel wire, and pull ring. The overall structure is compact, with no additional power module, and its size is greatly reduced compared to traditional equipment. It can be easily installed and used in small laboratories, field research sites, or grassroots medical institutions with limited space, effectively solving the problem of equipment space occupation and greatly improving the flexibility of use scenarios. Moreover, simply pulling the pull ring drives the blade to rotate and complete the pulverizing work. There is no need for complicated parameter settings and debugging. Researchers and production workers do not need long-term training and can easily get started, significantly shortening the equipment operation learning cycle and effectively improving sample processing efficiency.

[0017] 2. The collection box inside the shell of this utility model adopts a sliding connection design. After crushing, researchers or operators can easily pull out the collection box like a drawer. Without tilting or complicated disassembly steps, the material collection and transfer can be completed quickly, which significantly reduces the risk of material spillage and improves the convenience and safety of operation. The filter plate and filter hole design fixed on the top of the collection box can automatically screen the crushed material during the collection process, effectively separating particles of different sizes, retaining the material of the target particle size, and intercepting large particle impurities that do not meet the requirements, avoiding the tedious subsequent screening steps.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0026] Please see Figure 1-5 This utility model is a manual rapid tissue pulverizer, including a pulverizing shell 1, a pulverizing component 2 rotatably connected to the inner cavity of the pulverizing shell 1, and a collecting component 3 movably connected to the bottom of the pulverizing shell 1. The pulverizing component 2 includes a rotating rod 201, a blade 202 movably connected to the surface of the rotating rod 201, a coil 203 fixedly connected to the top of the rotating rod 201, the top of the coil 203 movably connected to the pulverizing shell 1, a steel wire 204 wound around the surface of the coil 203, one end of the steel wire 204 extending to the top of the pulverizing shell 1 and fixedly connected to a pull ring 205, the surface of the pull ring 205 slidably connected to the pulverizing shell 1, and a collecting component 3 including a housing 301, both sides of the top of the housing 301 slidably connected to the pulverizing shell 1, a collecting box 302 slidably connected to the inner cavity of the housing 301, a filter plate 303 provided on the top of the collecting box 302, one side of the filter plate 303 fixedly connected to the housing 301, and filter holes 304 opened on the surface of the filter plate 303.

[0027] Specifically: There are multiple blades 202, which can cut and grind materials more densely, greatly shorten the crushing time, and quickly crush large pieces of materials into fine particles. It is especially suitable for processing large batches of samples or hard materials, effectively improving the processing efficiency of experiments and production. The steel wire 204, blades 202 and wire spool 203 are all made of medical-grade stainless steel. Medical-grade stainless steel has good high temperature resistance and corrosion resistance. It can withstand high temperature and high pressure sterilization, ultraviolet irradiation or chemical reagent disinfection and other commonly used laboratory sterilization methods, avoiding the presence of bacteria and impurities due to the material's inability to withstand sterilization treatment. The crushing shell 1 is made of transparent polycarbonate material so that staff can directly observe the crushing process from the outside. Example 2

[0028] Please see Figure 1-5 Based on Embodiment 1, a limiting sleeve 4 is slidably connected to the surface of the steel wire 204. One side of the limiting sleeve 4 is fixedly connected to the crushing shell 1. A limiting groove 5 is opened on the top of the wire coil 203. A limiting disc 6 is slidably connected to the inner cavity of the limiting groove 5. One side of the limiting disc 6 is fixedly connected to the crushing shell 1. Sliding grooves 7 are opened on both sides of the inner cavity of the shell 301. A slider 8 is slidably connected to the inner cavity of the sliding groove 7. One side of the slider 8 is fixedly connected to the collection box 302. A limiting ring 9 is rotatably connected to the bottom of the rotating rod 201. The bottom of the limiting ring 9 is fixedly connected to the filter plate 303. A mounting plate 10 is fixedly connected to the surface of the housing 301. The other side of the mounting plate 10 is connected to the blade 202 by bolts. A positioning groove 11 is provided at the bottom of the mounting plate 10. One side of the blade 202 is slidably connected to the positioning groove 11. Rotating plates 12 are rotatably connected to both sides of the top of the housing 301. A magnetic card block 13 is fixedly connected to one side of the top of the rotating plate 12. A card slot 14 is provided on both sides of the crushing housing 1. One side of the magnetic card block 13 is engaged with the card slot 14. A magnetic suction block 15 is provided on one side of the magnetic card block 13. The other side of the magnetic suction block 15 is fixedly connected to the crushing housing 1.

[0029] Specifically: One end of the limiting sleeve 4 extends to the top of the inner cavity of the crushing shell 1, providing precise guidance and limiting for the steel wire 204. The sliding cooperation between the limiting groove 5 and the limiting disc 6 provides precise guidance for the rotation of the coil 203, preventing axial displacement or shaking of the coil 203 when the steel wire 204 is pulled. There are two sliding grooves 7 and two sliding blocks 8, allowing the collection box 302 to be completely pulled out of the shell 301 for subsequent cleaning or replacement. The setting of the limiting ring 9 can improve the stability of the rotating rod 201 when it rotates. When the blade 202 is worn or damaged, or needs to be replaced due to processing different samples, the limiting ring 9 can be used to prevent the blade 202 from being worn or damaged, or to prevent the blade from being replaced due to processing different samples. When using a specific type of blade 202, the blade 202 can be quickly replaced simply by unscrewing the bolts using conventional tools. The positioning groove 11 provides precise guidance and limit for the installation of the blade 202, ensuring that the blade 202 is accurately positioned during installation and avoiding uneven cutting caused by positional deviation. The engagement of the magnetic locking block 13 and the locking groove 14, combined with the magnetic attraction of the magnetic suction block 15, forms a double fixing effect. During the crushing operation, even if the equipment experiences severe vibration, it can ensure that the housing 301 and the crushing shell 1 are tightly connected, preventing sample leakage or equipment damage due to loose connection.

[0030] The working principle of this utility model is as follows: When in use, the material is put into the crushing shell 1 through the feed port at the center of the bottom connected to the shell 301. Then, the rotating plate 12 is rotated so that the magnetic card block 13 enters the inner cavity of the card slot 14 and is attracted to the magnetic block 15. Then, the pull ring 205 is pulled upward. The pull ring 205 drives the steel wire 204 to move along the limiting sleeve 4. The steel wire 204 drives the coil 203 to rotate along the limiting groove 5. The coil 203 drives the rotating rod 201 to rotate. The rotating rod 201 drives the mounting plate 10 to rotate. The blade 202 follows the mounting plate 10 to rotate and cuts and crushes the material. The qualified material falls into the collection box 302 at the bottom of the shell 301 through the filter hole 304 on the filter plate 303. The unqualified material stays in the inner cavity of the crushing shell 1 and continues to be crushed. Then, the collection box 302 is pulled out to collect the material inside.
