Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of crushing equipment, and more specifically, to an energy-saving electric medicine crusher. Background Art
[0002] The symptoms of Clostridium difficile infection range from asymptomatic carriers to severe diarrhea, colitis, and even life-threatening pseudomembranous colitis. For some patients with difficulty swallowing, the tablets used to treat Clostridium difficile need to be crushed to facilitate swallowing.
[0003] In the prior art, the electric crushers for crushing Clostridium difficile drugs are usually used by medical staff and are relatively small in size. Therefore, the crushing force of the internal crushing parts is not large. When a large number of tablets are put in at one time, the tablets stack on each other, resulting in an increase in the force required to crush the tablets. It is difficult for a small electric medicine crusher to quickly crush the stacked tablets in this situation, which causes the output end of the motor to need to output a greater power, increasing power consumption. At the same time, it also increases the risk of damage to the crushing roller and the motor. Moreover, the particle sizes of the crushed medicine powder are different, and there may be medicine powder that does not meet the requirement of being easy to swallow. At this time, the medicine powder with poor crushing effect needs to be crushed again, and during this process, medical staff also need to manually use a sieve for screening, which is time-consuming and laborious, affecting the efficiency of medicine crushing. At the same time, secondary crushing also increases the power consumption of the electric medicine crusher.

[0018] As described above, the characteristics and advantages of an energy-saving electric medicine crusher in the present invention are:
[0019] Through the settings of the connecting shaft and the movable shaft seat, when the extrusion force of the two crushing rollers on the tablets is too large, the crushing rollers drive the connecting shaft and the movable shaft seat to slide towards the push plate direction, so that the movable shaft seat squeezes the spring for buffering. After the difficult-to-crush tablets are crushed or slide out, the spring pushes the movable shaft seat to reset, thereby pushing the crushing rollers to reset, achieving the effect of the automatic movement of the crushing rollers when the crushing is difficult, avoiding damage caused by excessive torque at the output end of the motor, and increasing the output power of the motor;
[0020] Through the settings of the limiting groove and the limiting block, when the crushing roller moves, during the sliding process of the connecting shaft, the worm gear two is driven by the connecting piece to slide away from the rotating tube, so that the limiting block on the worm gear two partially slides out of the limiting groove, achieving the effect of synchronously moving with the crushing roller. At the same time, the limiting block does not completely slide out of the limiting groove, and when the rotating tube rotates, the worm gear two can be driven to rotate through the cooperation of the limiting groove and the limiting block, so as to continue to drive the crushing roller to rotate through the worm gear two, maintaining the crushing effect on the tablets;
[0021] Through the settings of the medicine distribution cavity and the medicine distribution wheel, the motor drives the bevel gear one to rotate through the rotating rod, and the bevel gear one drives the medicine distribution wheel to rotate through the bevel gear two. After the medicine distribution wheel starts to rotate, the empty material distribution groove is rotated to directly below the feeding port, and the tablets that have not entered the medicine distribution groove slide into the medicine distribution groove under the action of gravity. After the medicine distribution groove with tablets rotates to directly below the medicine distribution wheel, the tablets fall between the crushing rollers under the action of gravity. Under the continuous rotation of the medicine distribution wheel, quantitative and intermittent medicine feeding is realized, thereby avoiding tablet jams. At the same time, when the tablets are evenly distributed, the crushing effect of the tablets can be improved, and thus the purpose of feeding is achieved;
[0022] Through the cooperation of the spring and the movable shaft seat, when the crushing roller moves under the extrusion of the tablets, causing the connecting shaft to drive the movable shaft seat to squeeze the push plate, the thrust of the push plate on the movable shaft seat increases. Therefore, the force for the movable shaft seat to drive the crushing roller to slide away from the push plate through the connecting shaft increases. Furthermore, the pressure of the crushing roller on the tablets after movement increases, assisting the crushing roller to crush the tablets. Thus, when the tablets are difficult to crush, the crushing roller can move horizontally to avoid excessive torque at the output end of the motor. At the same time, the push plate assists the crushing roller to crush, reducing the consumption of the motor and achieving the effect of energy-saving grinding of the tablets;
[0023] Through the setting of the sieve plate, the sliding seat drives the sieve plate to move up and down rapidly through the connecting rod. When the medicinal powder crushed by the crushing roller falls to the top of the sieve plate, under the up and down movement of the sieve plate, the medicinal powder moves on the top of the sieve plate. The medicinal powder with a smaller particle size can pass through the holes of the sieve plate and then fall into the tray for patients to use. The medicinal powder whose particle size after crushing does not meet the use requirements cannot pass through the sieve plate. Under the action of the inclined setting and continuous up and down movement of the sieve plate, the medicinal powder gradually approaches the discharge port, and then is shaken into the discharge port by the sieve plate and slides out of the crushing box, realizing the function of screening out the medicinal powder whose particle size does not meet the use requirements. At the same time, the continuous movement of the sieve plate can assist in the discharge of the medicinal powder, avoiding the situation that the medicinal powder is difficult to be discharged from the device, resulting in inconvenient collection.
[0024] Through the setting of the bolt and the push plate, according to the different specifications or batches of the tablets, the hardness of the tablets is different. When crushing the tablets with a greater hardness, medical staff can use tools to rotate the bolt, so that the bolt further rotates into the circular groove, thereby pushing the push plate to slide in the direction close to the movable shaft seat. After the spring is further compressed, the thrust on the movable shaft seat increases. When the crushing roller is pressed again and moves, and drives the movable shaft seat to press the spring through the connecting shaft, the thrust of the spring on the movable shaft seat increases, so that the extrusion force of the crushing roller on the tablets increases, thus adapting to the crushing of tablets with a greater hardness, and there is no need to increase the power of the motor, reducing the consumption of the motor and achieving the effect of energy saving.

The limiting blocks 315 are slidably connected with the limiting grooves 314 in a limiting manner. The rotating tube 306 can drive the two second worms 307 to rotate through the limiting blocks 315 and the limiting grooves 314.
[0044] Further, as Figures 1 to 4 shown, a material distributing assembly is arranged in the crushing box 1. The material distributing assembly includes a motor 401 fixedly installed on the top of the fixed box 301.

[0045] Further, as Figure 1 、 Figures 7 to 9As shown in the figure, a pressurizing component is arranged inside the crushing box 1. The pressurizing component includes a push plate 501 slidably connected in the movable groove 311. A spring 502 is arranged between the push plate 501 and the movable shaft seat 312.

The discharging port 607 is located at the bottom end of the sieve plate 606. A cover plate is arranged inside the discharging port 607.
[0047] Combined with the above embodiments, the following is the entire working process and working principle of the above embodiments:
[0048] The initial state is:
[0049] The second worm 307 has not slid out of the rotating tube 306, the spring 502 is in a compressed state, the movable shaft seat 312 is located on the side of the movable groove 311 far from the push plate 501, the motor 401 is not powered on, the bolt 504 has not rotated, and the push plate 501 is in contact with the inner wall of the movable groove 311 on the side close to the bolt 504.
[0050] The working state is:
[0051] Uniform medicine feeding:
[0052] When a patient with dysphagia needs to use a drug for Clostridium difficile infection, the medical staff puts the tablets into the feeding port 2. After the tablets enter the feeding port 2, they slide into the dosing chamber 404 through the inclined plane of the feeding port 2, and then fall into the dosing grooves on the top of the dosing wheel 405. At this time, the motor 401 is started. The motor 401 drives the first bevel gear 402 to rotate through the rotating rod 303. The first bevel gear 402 drives the dosing wheel 405 to rotate through the second bevel gear 403. After the dosing wheel 405 starts to rotate, the empty dosing groove is rotated to directly below the feeding port 2, and the remaining tablets continue to slide into the dosing grooves under the action of gravity. After the dosing groove with tablets rotates to directly below the dosing wheel 405, the tablets fall between the crushing rollers 310 under the action of gravity. Under the continuous rotation of the dosing wheel 405, quantitative and intermittent drug delivery is achieved, thus avoiding tablet jamming. At the same time, when the tablets are evenly distributed, the crushing effect of the tablets can be improved, and the situation of tablet stacking can be reduced, further reducing the consumption of the motor 401 and achieving the effect of energy-saving crushing.
[0053] Crushing tablets:
[0054] After the motor 401 is started and drives the rotating rod 303 to rotate, the rotating rod 303 drives the first worm 304 to rotate, so that the first worm wheel 305 rotates, causing the rotating tube 306 to rotate. Thus, the rotating tube 306 drives two second worms 307 to rotate through the limiting groove 314 and the limiting block 315, and further drives two second worm wheels 308 to rotate. The second worm wheel 308 drives the crushing rollers 310 to rotate through the connecting shaft 309, and the two crushing rollers 310 rotate simultaneously to crush the falling tablets.
[0055] Vibrating discharging:
[0056] Before collecting the crushed medicine powder, the tray for collecting the medicine powder can be placed directly below the crushing box 1. When the motor 401 drives the first worm 304 to rotate through the rotating rod 303, the reciprocating threaded rod 601 at the bottom of the first worm 304 rotates synchronously. The reciprocating threaded rod 601 drives the sliding seat 602 to reciprocate through the reciprocating thread, so that the sliding seat 602 drives the sieve plate 606 to move up and down quickly through the connecting rod 605. When the medicine powder crushed by the crushing rollers 310 falls onto the top of the sieve plate 606, under the up and down movement of the sieve plate 606, the medicine powder moves on the top of the sieve plate 606, and the medicine powder with a smaller particle size can pass through the holes of the sieve plate 606, and thus falls into the tray after passing through the sieve plate 606 for the patient to use. The medicine powder whose particle size after crushing does not meet the use requirements cannot pass through the sieve plate 606. Under the action of the inclined setting and continuous up and down movement of the sieve plate 606, the medicine powder gradually approaches the discharge port 607, and then is shaken into the discharge port 607 by the sieve plate 606 and slides out of the crushing box 1, realizing the function of screening out the medicine powder whose particle size does not meet the use requirements. At the same time, the continuous movement of the sieve plate 606 can assist the discharge of the medicine powder and avoid the situation that the medicine powder is difficult to discharge from the device, resulting in inconvenient collection.
[0057] The crushing roller 310 moves:
[0058] When crushing tablets, there will be a situation where it is difficult to crush the stacked tablets on the crushing roller 310. When the extrusion force of the tablets on the two crushing rollers 310 is too large, the crushing roller 310 drives the connecting shaft 309 and the movable shaft seat 312 to slide towards the push plate 501, so that the movable shaft seat 312 squeezes the spring 502 for buffering. During this process, when the connecting shaft 309 slides, it drives the second worm 307 to slide away from the rotating tube 306 through the connecting piece 313. The second worm 307 moves synchronously with the second worm gear 308, so that the limiting block 315 on the second worm 307 partially slides out of the limiting groove 314, achieving the effect of moving synchronously with the crushing roller 310. At the same time, the limiting block 315 does not completely slide out of the limiting groove 314. When the rotating tube 306 rotates, it can drive the second worm 307 to rotate through the cooperation of the limiting groove 314 and the limiting block 315, and then continue to drive the crushing roller 310 to rotate through the second worm gear 308. When the difficult-to-crush tablets are crushed or slide out between the crushing rollers 310, the spring 502 pushes the movable shaft seat 312 to reset, thereby pushing the crushing roller 310 to reset, achieving the effect that the crushing roller 310 automatically moves when crushing is difficult, avoiding damage caused by excessive torque at the output end of the motor 401 and increasing the power consumption of the motor 401.
[0059] Pressurized crushing:
[0060] When the crushing roller 310 moves under the extrusion of the tablets, causing the connecting shaft 309 to drive the movable shaft seat 312 to squeeze the push plate 501, the thrust of the push plate 501 on the movable shaft seat 312 increases. Thus, the force for the movable shaft seat 312 to drive the crushing roller 310 to slide away from the push plate 501 through the connecting shaft 309 increases, making the pressure of the crushing roller 310 on the tablets increase after movement, assisting the crushing roller 310 to crush the tablets. Therefore, when it is difficult to crush the tablets, the crushing roller 310 moves to avoid excessive torque at the output end of the motor 401, and at the same time, the push plate 501 assists the crushing roller 310 to crush, reducing the consumption of the motor 401 and achieving the effect of energy-saving grinding of tablets.
[0061] Manual pressurization:
[0062] Depending on the tablet specifications or batches, the hardness of the tablets is different. When crushing tablets with greater hardness, medical staff can use a tool to rotate the bolt 504, causing the bolt 504 to rotate further into the circular groove 503, thereby pushing the push plate 501 to slide in the direction closer to the movable shaft seat 312, so as to cooperate with the movable shaft seat 312 to compress the spring 502. After the spring 502 is further compressed, the thrust on the movable shaft seat 312 increases. When the crushing roller 310 is squeezed again and moves, driving the movable shaft seat 312 to squeeze the spring 502 through the connecting shaft 309, the thrust of the spring 502 on the movable shaft seat 312 increases, making the squeezing force of the crushing roller 310 on the tablets increase, thus adapting to the crushing of tablets with greater hardness, without the need to increase the power of the motor 401, reducing the consumption of the motor 401, and at the same time helping to achieve a better drug crushing effect, reducing the situation where the drug powder needs to be crushed a second time, and achieving the effect of energy conservation.
[0063] Energy-saving crushing:
[0064] The rotating rod 303 is driven to rotate by the motor 401, and at the same time, the worm 304 and the reciprocating threaded rod 601 are driven to rotate, thereby driving the medicine distributing wheel 405 and the crushing roller 310 to rotate respectively, and driving the sieve plate 606 to swing. When only one motor 401 is set, the effects of material distribution, crushing and blanking are achieved at the same time. At the same time, the push plate 501 is used to assist the crushing roller 310 in crushing, achieving the effect of energy-saving drug crushing, making the drug crusher more environmentally friendly, and at the same time improving the economic benefits during drug crushing.
[0065] The above are only the embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
