Description

Technical Field

[0001] This utility model relates to the field of extraction technology, specifically to a fat extraction device. Background Technology

[0002] Fat extraction is a common sample pretreatment step in many fields such as food, biology, and environment, and is widely used in experiments such as fat content determination and component analysis. Traditional fat extraction methods, such as manual shaking, mainly rely on operators to manually shake the container to promote the mixing of solvent and sample and the dissolution of fat.

[0003] However, these traditional methods have significant technical drawbacks. First, the frequency, amplitude, and force of manual shaking are difficult to control precisely and consistently, easily leading to uneven shaking. This unevenness results in insufficient separation of fat from other components such as protein and water in the sample, not only prolonging the extraction time but also potentially affecting the purity and recovery rate of the final extracted fat due to incomplete separation, thus impacting the accuracy of the test results. Utility Model Content

[0004] In view of this, the present invention provides a fat extraction device to solve or improve the problems existing in manual shaking.

[0005] This utility model provides a fat extraction device, comprising:

[0006] A support member, used to fix the experimental container, is movable;

[0007] The device includes a rotation drive, a rotating rod, and a swing rod. The rotation drive is fixedly installed and has an output shaft connected to the rotating rod, which drives the rotating rod to rotate. One end of the swing rod is rotatably connected to the rotating rod, and the other end is rotatably connected to the support member, which drives the support member to move.

[0008] In one optional embodiment, the carrier includes a housing with a receiving cavity for accommodating the experimental container, and the housing also has an opening communicating with the receiving cavity for placing or removing the experimental container.

[0009] In one optional embodiment, the carrier further includes a carrier plate that can enter and exit the receiving cavity through the opening, and the carrier plate is provided with a slot for fixing the experimental container.

[0010] In one alternative embodiment, the number of the support plates is at least two, and the at least two support plates are stacked. Between two adjacent support plates, one support plate is provided with an insertion hole, and the other support plate is provided with a plug for insertion into the insertion hole.

[0011] In one optional embodiment, the support plate has a square structure, and the four corners of the support plate are provided with the insertion hole or the insertion rod.

[0012] In one optional embodiment, the support plate is provided with a plurality of slots, the plurality of slots are arranged sequentially at intervals, and the arrangement direction of the slots is perpendicular to the moving direction of the support member;

[0013] And / or, the extension direction of the slot is consistent with the movement direction of the carrier, so that the length direction of the experimental container in the slot is consistent with the movement direction of the carrier.

[0014] In one alternative embodiment, the fat extraction device further includes a connecting rod, one end of which is connected to the support member and the other end of which is rotatably connected to the swing rod.

[0015] In one optional embodiment, the fat extraction device further includes a support, which is fixedly disposed, the rotation drive device is mounted on the support, and the connecting rod is slidably connected to the support.

[0016] In one optional embodiment, the swing rod includes a rod body and a connector, with the connector connected to both ends of the rod body.

[0019] Furthermore, uniform oscillation effectively promotes the separation of fat from other components such as protein and water, eliminating the need for repeated shaking and waiting for separation as in manual operations, thus significantly shortening the extraction time. On the other hand, standardized mechanical operation reduces "human error," significantly reducing differences in fat purity and recovery rate between samples from the same batch and different batches, thereby improving the repeatability and reliability of the test results.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Traditional fat extraction methods, such as manual shaking, mainly rely on operators to manually shake the container to promote the mixing of solvent and sample and the dissolution of fat.

[0030] However, these traditional methods have significant technical drawbacks. First, the frequency, amplitude, and force of manual shaking are difficult to control precisely and consistently, easily leading to uneven shaking. This unevenness results in insufficient separation of fat from other components such as protein and water in the sample, not only prolonging the extraction time but also potentially affecting the purity and recovery rate of the final extracted fat due to incomplete separation, thus impacting the accuracy of the test results.

[0031] To address or improve the problems associated with manual shaking, this invention provides a fat extraction device.

[0032] The following is combined with Figures 1 to 4 This describes the fat extraction device provided in the embodiments of the present invention.

[0033] Specifically, the fat extraction device includes a support 1, a rotation drive device 2, a rotating rod 3, and a swing rod 4.

[0034] The support member 1 is used to fix the experimental container, such as, but not limited to, a Mao's liposuction bottle. The support member 1 is movable, for example, the support member 1 is movable in the horizontal direction.

[0035] The rotary drive device 2 is fixedly installed and has an output shaft. It is understood that "fixedly installed" means that the housing of the rotary drive device 2 is fixed and will not shift during operation. Optionally, the rotary drive device 2 may include, but is not limited to, an electric motor and a pneumatic motor.

[0036] The output shaft of the rotary drive device 2 is connected to the rotating rod 3 and is used to drive the rotating rod 3 to rotate. One end of the swing rod 4 is rotatably connected to the rotating rod 3, and the other end of the swing rod 4 is rotatably connected to the carrier 1 and is used to drive the carrier 1 to move. That is, the rotating rod 3, the swing rod 4, and the carrier 1 can form a crank-slider mechanism, with the rotating rod 3 serving as the crank of the crank-slider mechanism and the carrier 1 serving as the slider of the crank-slider mechanism.

[0037] In this embodiment, during use, the rotation drive device 2 is activated, its output shaft begins to rotate, and drives the connected rotating rod 3 to perform circular motion around the axis of the output shaft. When the rotating rod 3 performs circular motion, it is converted into the reciprocating oscillation of the swing rod 4 through its connection with the swing rod 4.

[0038] During the reciprocating swing of the swing rod 4, it pushes or pulls the carrier 1, causing the carrier 1 to move back and forth in the horizontal direction. The experimental container oscillates stably with the carrier 1, and the solvent and sample inside the container are fully mixed under the continuous and uniform oscillation, ultimately achieving efficient dissolution of fat.

[0039] With this setup, by adjusting the rotation speed of the drive device 2 (such as the speed of the motor), the reciprocating frequency of the bearing 1 can be precisely controlled, completely avoiding the problem of "sometimes fast, sometimes slow, sometimes strong, sometimes weak" in manual operation, ensuring that the oscillation conditions of each extraction experiment are completely consistent, and providing a basic guarantee for the stability of the experimental results.

[0040] Furthermore, uniform oscillation effectively promotes the separation of fat from other components such as protein and water, eliminating the need for repeated shaking and waiting for separation as in manual operations, thus significantly shortening the extraction time. On the other hand, standardized mechanical operation reduces "human error," significantly reducing differences in fat purity and recovery rate between samples from the same batch and different batches, thereby improving the repeatability and reliability of the test results.

[0041] In addition, the fat extraction device replaces the manual shaking operation, greatly reducing the physical exertion of operators, and is especially suitable for batch sample extraction scenarios.

[0042] In some embodiments provided by this utility model, the carrier 1 includes a housing 101. The housing 101 is provided with a receiving cavity for accommodating experimental containers. The housing 101 is also provided with an opening 1011 communicating with the receiving cavity, the opening 1011 being used for taking out and placing experimental containers.

[0043] In this embodiment, during the oscillation process, the experimental container is constrained within the box 101, and even when the oscillation amplitude is large, it will not tip over, shift, or collide, thus improving operational stability.

[0044] In addition, the opening 1011 is connected to the receiving cavity and serves as a channel for taking out and putting in the experimental container. The opening 1011 can be set on the top or side of the box 101. In other embodiments, an openable and closable cover can be set at the opening 1011. During the oscillation process, the cover is used to close the opening 1011 to reduce noise and improve the quietness and safety of the operating environment.

[0045] In some embodiments provided by this utility model, the support member 1 further includes a support plate 102, which can enter and exit the receiving cavity through the opening 1011. The support plate 102 is provided with a slot 1021 for fixing the experimental container.

[0046] In this embodiment, the support plate 102 can enter and exit the housing 101 through the opening 1011, enabling rapid loading and unloading of the experimental container. In addition, the slot 1021 on the support plate 102 matches the shape of the experimental container, and can restrict the experimental container through a "click-locking" method, thereby further preventing the experimental container from tipping over, rotating or shifting during oscillation.

[0047] refer to Figure 2As shown, in some embodiments of this utility model, the number of support plates 102 is at least two, and at least two support plates 102 are stacked. Between two adjacent support plates 102, one support plate 102 is provided with an insertion hole 1022, and the other support plate 102 is provided with a plug 1023 for insertion into the insertion hole 1022. For example, the figure shows an example where, between two stacked support plates 102, the upper support plate 102 is provided with a plug 1023, and the lower support plate 102 is provided with an insertion hole 1022. It can be understood that the reverse is also possible.

[0048] In this embodiment, at least two support plates 102 are stacked, which is equivalent to building a "multi-layer fixed platform" in the cavity of the box 101. Without increasing the volume of the box 101, the single container load capacity can be doubled, which is especially suitable for laboratory batch testing scenarios and greatly improves space utilization.

[0049] In addition, in the adjacent support plates 102, one is provided with an insertion hole 1022 and the other with an insertion rod 1023. The two are inserted and cooperated to quickly align the positions of each layer of support plates 102, ensuring that each layer of slot 1021 is on the same vertical line to avoid interlayer misalignment, and to limit interlayer horizontal displacement to prevent the multilayer boards from sliding relative to each other during oscillation.

[0050] In some embodiments provided by this utility model, the support plate 102 has a square structure, and each of the four corners of the support plate 102 is provided with a hole 1022 or a rod 1023.

[0051] In this embodiment, the four corners of the support plate 102 are provided with insertion holes 1022 or insertion rods 1023 to form a four-point positioning. The four corners can restrict interlayer displacement from all directions in the horizontal direction, avoid the support plate 102 from tilting or shifting during oscillation, and ensure that the multilayer board always remains parallel and aligned.

[0052] In addition, the four-corner positioning makes the connection points of adjacent bearing plates 102 more evenly distributed and the force more balanced. Even if the oscillation frequency is high or the experimental container is heavy, it can avoid the single-sided warping or relative sliding between layers, further ensuring that the oscillation trajectory of each experimental container is consistent and reducing detection errors.

[0053] In some embodiments provided by this utility model, the support plate 102 is provided with a plurality of slots 1021, the plurality of slots 1021 are arranged in sequence at intervals, and the arrangement direction of the slots 1021 is perpendicular to the moving direction of the support member 1.

[0054] In this embodiment, multiple slots 1021 are arranged sequentially at intervals, enabling batch fixing of experimental containers on a single support plate 102, and the spacing design avoids collisions between experimental containers. In addition, the vertical arrangement ensures that the containers in all slots 1021 experience completely consistent forces and displacement trajectories when the support 1 moves, resulting in uniform mixing of solvent and sample in each experimental container during batch processing, thus improving the repeatability of test results.

[0055] In some embodiments provided by this utility model, the extending direction of the slot 1021 is consistent with the moving direction of the support member 1, so that the length direction of the experimental container in the slot 1021 is consistent with the moving direction of the support member 1.

[0056] In this embodiment, the extension direction of the slot 1021 is consistent with the horizontal reciprocating direction of the support member 1, so that the experimental container can be embedded into the slot 1021 along its length direction, and the length direction of the container is consistent with the oscillation direction. When the support member 1 moves back and forth, the force direction on the container is consistent with its own length direction, avoiding the container from tilting or twisting in the slot 1021 due to lateral force. At the same time, it is conducive to the solvent forming a directional flow in the bottle, improving mixing efficiency and extraction uniformity.

[0057] Optionally, the opening 1011 is located on the top of the housing 101, and the support plate 102 may be provided with a handle groove.

[0058] In this embodiment, the opening 1011 is located at the top of the box 101, which makes it easier to vertically insert or remove the support plate 102, making the operation more convenient and labor-saving. At the same time, it reduces the risk of the support plate 102 sliding out of the opening 1011 during the oscillation process.

[0059] In addition, the edge of the support plate 102 is provided with a recessed handle groove, which provides a point of application for fingers to grasp the support plate 102 to complete the pick-up and put-down operation. At the same time, the handle groove will not interfere with or hook up with adjacent support plates 102.

[0060] In some embodiments of this invention, a transparent observation window is provided on the side wall of the housing 101. Optionally, the observation window is made of a transparent material, such as glass or acrylic.

[0061] In this embodiment, the observation window is embedded in the side wall of the box 101, which not only does not damage the fixing and protection function of the box 101 for the container, but also allows the operator to observe the status of the experimental container in the containment cavity in real time, and can grasp the progress of fat dissolution without opening the box 101.

[0062] In some embodiments of this utility model, a heating device is provided in the housing 101. Optionally, the heating device is disposed on the side wall or bottom of the housing 101, or the heating device is disposed on the support plate 102, and can be used to regulate the temperature inside the housing 101. Optionally, the heating device can be an electric heating wire or a heating tube, and the heating tube can be heated by electricity or hot water.

[0063] In this embodiment, the heating device can regulate the conditions inside the chamber 101. For example, when the temperature is appropriately increased, the interfacial tension between the fat and the solvent can be reduced, the diffusion of fat molecules can be accelerated, and the extraction time can be further shortened by oscillation mixing.

[0064] Furthermore, a temperature detection device is also provided inside the enclosure 101, and both the temperature detection device and the heating device are electrically connected to the controller. Optionally, the temperature detection device can be a thermocouple or a temperature sensor.

[0065] In this embodiment, the temperature detection device collects the temperature inside the chamber 101 in real time and transmits the data to the controller. The controller automatically adjusts the power of the heating device based on the difference between the preset temperature threshold and the real-time data, thereby achieving precise and stable temperature control inside the chamber 101 and ensuring that fat extraction is always carried out within the set temperature environment.

[0066] In some embodiments of this invention, the fat extraction device further includes a connecting rod 5. One end of the connecting rod 5 is connected to the support member 1, and the other end is rotatably connected to the swing rod 4. For example, the connecting rod 5 can be threaded or welded to the support member 1.

[0067] In this embodiment, a connecting rod 5 is added, with one end connected to the bearing 1 and the other end rotatably connected to the swing rod 4. This allows for flexible adjustment of the connection position and angle between the bearing 1 and the swing rod 4, thereby helping to optimize the transmission path, ensure smooth transmission of oscillating motion, facilitate assembly and maintenance, and improve the adaptability and reliability of the device.

[0068] In some embodiments of this utility model, the fat extraction device further includes a support 6, which is fixedly installed. A rotation drive device 2 is mounted on the support 6, for example, the rotation drive device 2 is screwed onto the support 6. A connecting rod 5 is slidably connected to the support 6, for example, the support 6 is provided with a guide groove or guide hole or other guide structure, and the connecting rod 5 is slidably engaged with the guide structure.

[0069] In this embodiment, during use, the support 6 can be fixed to the support surface of the experimental table, with one end of the support 6 protruding beyond the edge of the support surface. The rotation drive device 2 is disposed on the part of the support 6 protruding beyond the edge of the support surface and is located below the support 6. The output shaft of the rotation drive device 2 passes through the support 6 and is connected to the rotation rod. The housing 101 is slidably disposed on the support surface and is connected to the connecting rod 5.

[0070] With this configuration, one end of the support 6 is fixed to the support surface of the experimental table, and the other end protrudes from the edge. The rotation drive device 2 is arranged below the protruding part. This not only makes use of the suspended space at the edge of the experimental table, saving table space, but also keeps the drive device away from the main working area of ​​the operator.

[0071] The housing 101 is placed on the support surface of the experimental platform, and the flatness of the support surface enables stable sliding, which simplifies the overall structure. Of course, in some embodiments not shown, guide rails can also be provided on the support surface, allowing the housing 101 to slide in conjunction with the guide rails.

[0072] In some embodiments provided by this utility model, the swing rod 4 includes a rod body 401 and a connector 402.

[0073] Both ends of the rod 401 are connected to connectors 402. Connector 402 at one end of the rod 401 is rotatably connected to the rotating rod 3, and connector 402 at the other end of the rod 401 is rotatably connected to the bearing 1.

[0074] In this embodiment, the rod 401 serves as the main body of the swing rod 4. The rod 401 bears the function of force transmission, converting the circular motion of the rotating rod 3 into the reciprocating power of the push-pull bearing 1. Its length and rigidity directly affect the transmission efficiency. The two end connectors 402 form a rotational connection with the rotating rod 3 and the bearing 1, respectively. The connectors 402 can be designed with adaptable structures to meet the connection requirements of different components, ensuring smooth rotation without jamming.

[0075] Furthermore, connector 402 optimizes the fit precision of the rotating pair, reduces the relative friction and gap between rod 401 and rotating rod 3 and bearing 1, making power transmission smoother and avoiding erratic oscillations caused by loose connections. Simultaneously, the modular design facilitates individual replacement of worn connector 402 without requiring complete replacement of the swing rod 4, reducing maintenance costs.

[0076] In some embodiments provided by this utility model, the rod body 401 is threadedly connected to the connector 402 at least at one end. For example, the end of the rod body 401 is provided with an external thread, and the connector 402 is provided with an internal thread.

[0077] In this embodiment, the rod 401 and the connector 402 are threaded together. Rotating the connector 402 can change the engagement length of the two, thereby precisely adjusting the total length of the swing rod 4, and thus flexibly adjusting the length of the transmission arm according to experimental requirements.

[0078] For example, by adjusting the length of the swing rod 4, the oscillation stroke requirements of different samples can be adapted, improving the versatility of the device. In addition, the length of the swing rod 4 can be finely adjusted to compensate for machining or assembly errors, ensuring precise alignment of the transmission centers of the rotating rod 3, the swing rod 4, and the carrier 1, reducing mechanical jamming.

[0079] Furthermore, the swing arm 4 also includes a locking nut 403. The locking nut 403 is threadedly connected to the swing arm 4 and abuts against the connector 402. Accordingly, each connector 402 is provided with a corresponding locking nut 403.

[0080] In this embodiment, a locking nut 403 is added, which is threadedly connected to the swing rod 4 and abuts against the connector 402. This prevents the connector 402 from changing its screw depth due to loosening during vibration, thereby ensuring that the adjusted length of the swing rod 4 is stable and reliable, avoiding loosening during operation, and improving transmission accuracy and equipment safety.

[0081] In some embodiments provided by this utility model, the output shaft extends along the height direction of the housing 101, that is, both the rotating rod 3 and the swing rod 4 move in the horizontal plane. This arrangement can save the space occupied by the rotating rod 3 and the swing rod 4 in the height direction during their movement, making the overall structure of the device flatter and more compact.

[0082] In some embodiments of this invention, the fat extraction device further includes a protective cover, with at least a portion of the rotating rod 3, the swing rod 4, and the rotation drive device 2 disposed within the protective cover. For example, the protective cover may be a metal cover or a plastic shell.

[0083] In this embodiment, the high-speed rotating rod 3 and the reciprocating swing rod 4 are isolated from the outside environment to avoid the risk of scratches or entanglement caused by operators coming into contact with moving parts. Furthermore, the protective cover can prevent dust, solvent splashes, sample debris, etc., from entering the transmission gap, reducing component wear or jamming caused by impurities and lowering maintenance frequency; it also prevents damage to the precision transmission structure from external impacts. Additionally, it can reduce operating noise to a certain extent, maintaining a clean and quiet laboratory environment.

[0084] In some embodiments of this invention, the fat extraction apparatus further includes a display device, such as a display screen or monitor. Both the display device and the rotation drive device 2 are connected to a controller, and the monitor displays at least one of the oscillation duration, oscillation frequency, and rotational speed of the output shaft.

[0085] It is understandable that, given the known dimensions and relative positions of components such as rotating rod 3 and swing rod 4, the oscillation frequency can be calculated based on the rotational speed of the output shaft.

[0086] In this embodiment, the display device serves as a human-machine interface. It receives real-time operating data of the rotation drive device 2 through the controller, such as the oscillation frequency converted from the motor speed and the cumulative running time. The data is presented intuitively in a digital or graphical manner, so that the operator can accurately grasp the extraction process and parameter matching degree without relying on experience to judge the equipment status.

[0087] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
