Description

Technical Field

[0001] This application relates to an ice processing device, and more particularly to an ice crushing device. Background Technology

[0002] In organ transplantation surgery, maintaining the viability of transplanted organs such as the liver and heart is crucial for surgical success. Typically, transplanted organs require a stable cryogenic storage environment to prevent loss of viability due to temperature fluctuations. Currently, clinical practice commonly uses uniformly sized ice blocks made from physiological saline to provide such cryogenic storage conditions. These ice blocks are mostly produced by automated ice crushers, which break down large blocks of ice to obtain smaller ice blocks that meet clinical needs.

[0003] In clinical surgery, to ensure the ice particles provided meet sterility requirements, the interior of the ice crusher, especially the crushing blades that come into direct contact with the ice, must be thoroughly disinfected regularly. The equipment itself also requires routine maintenance and repair, necessitating easy disassembly and reassembly of its internal components. However, in existing ice crushers, the internal components are interconnected and mutually restrictive. If a malfunction occurs or only the crushing blades need replacing, multiple interconnected components must be disassembled. This process is not only cumbersome and time-consuming but also makes daily maintenance extremely inconvenient. Furthermore, due to the strong interdependence and high positioning precision of the components, reassembly after disassembly often fails to restore the original assembly accuracy, thus affecting the subsequent ice crushing effect.

[0004] Therefore, there is an urgent need for an ice-crushing device. The structural design of this device can not only enable the quick disassembly and replacement of the ice-crushing blade for convenient daily disinfection, sterilization, maintenance and repair, but also ensure that the reassembly process is simple and reliable, so that the connection between the blade and the main unit is both quick and firm, thus maintaining the original ice-crushing effect after reassembly and ensuring the stability of the device operation. Summary of the Invention

[0005] To address the aforementioned issues, this application discloses an ice-crushing device that connects a drive motor and an ice-crushing blade via a shaft, and includes a mechanism capable of driving the shaft axially. This allows for rapid switching between engaged and disengaged states between the drive motor and the ice-crushing blade, simplifying the assembly relationship between them and enabling quick disassembly and installation of the ice-crushing blade, thus making routine maintenance and replacement operations more efficient. Furthermore, this axial movement connection method allows for rapid and precise alignment and reset of the shaft after ice-crushing blade replacement, ensuring connection reliability and guaranteeing the stability of the device's subsequent operation.

[0006] To achieve the above objectives, this application adopts the following technical solution: This application provides an ice-crushing device, which includes a frame, an ice-crushing chamber, a drive motor, a transmission screw, and a connecting arm. The ice-crushing chamber is detachably mounted on the frame, and an ice-crushing blade is disposed inside the ice-crushing chamber. The drive motor is fixed to the frame and is provided with a drive shaft and a sliding shaft that drives the drive shaft axially. The sliding shaft can also slide axially relative to the drive shaft between an engaged position and a disengaged position to achieve transmission connection or disconnection with the ice-crushing blade. The transmission screw is rotatably mounted on the frame. The connecting arm has a transmission part that can be threadedly connected to the transmission screw and a clamping part that can be connected to the bearing of the sliding shaft. The connecting arm driven by the transmission screw can drive the sliding shaft to switch from the engaged position to the disengaged position. When the connecting arm is in the engaged position, the clamping part of the connecting arm can clamp and fix the ice-crushing chamber. When the connecting arm is in the disengaged position, the clamping part of the connecting arm can disengage from clamping and fixing the ice-crushing chamber.

[0007] This device connects a fixed drive motor and an ice-crushing blade via a drive shaft and a movable sliding shaft. It also includes a connecting arm that allows the sliding shaft to move axially relative to the drive shaft. This enables rapid switching between engaged and disengaged states between the drive motor and the ice-crushing blade, simplifying the assembly process. Simply moving the sliding shaft disengages the drive motor from the ice-crushing blade, facilitating quick disassembly and installation. This also aids in routine maintenance and sterilization of the ice-crushing blade. Furthermore, the connecting arm's design allows for quick and precise alignment and reset of the sliding shaft and the ice-crushing blade after replacement, ensuring reliable connection. Simultaneously, it clamps and secures the ice-crushing chamber, ensuring its stable placement within the frame and guaranteeing the stable operation of the ice-crushing blade inside, preventing any impact on the ice-crushing effect after reassembly.

[0008] In one illustrative embodiment of the ice-crushing device, the drive shaft has a insertion cavity, the inner wall of which is provided with a keyway arranged axially; the sliding shaft has a sliding end that is slidably connected to the drive shaft, and the outer wall of the sliding end is provided with a connecting key that can connect with the keyway, and the connecting key can also slide along the keyway. This key-to-keyway connection method allows the sliding shaft to slide relative to the drive shaft while simultaneously enabling the drive shaft to stably drive the sliding shaft to rotate in the same direction, thereby causing the drive shaft to drive the rotation of the ice-crushing blade, and enabling the sliding shaft to perform a good transmission function.

[0009] In one illustrative embodiment of the ice crushing device, the sliding shaft has a connecting end opposite to the sliding end, and the outer wall of the connecting end is provided with a first spline; the outer side of the end face of the ice crushing chamber is provided with a second spline capable of driving the ice crushing blade to rotate; the clamping part of the connecting arm is provided with a linkage sleeve, the two ends of which can be connected to the first spline and the second spline respectively; the linkage sleeve in the clutch position can disengage from the key connection with the second spline and can push the sliding shaft to the clutch position. This linkage sleeve and spline connection method enables the sliding shaft to achieve a firm fit with the ice crushing blade, ensuring the tightness of the connection and ensuring that the sliding shaft can stably drive the ice crushing blade to rotate. On the other hand, the design of the linkage sleeve also allows the sliding shaft and the ice crushing chamber to achieve quick and precise docking after reassembly, thereby ensuring the normal operation of the equipment afterwards.

[0010] In one illustrative embodiment of the ice-crushing device, the device further includes an elastic element. One end of the elastic element abuts against the drive shaft, and the other end abuts against the first spline. The elastic element provides an elastic force to the sliding shaft. During the process of the transmission screw driving the connecting arm to clamp and fix the ice-crushing chamber, the elastic force can push the sliding shaft to maintain a keyed connection with the linkage sleeve. The design of the elastic element ensures that the sliding shaft can always maintain a keyed connection with the linkage sleeve, preventing the sliding shaft from falling out of the linkage sleeve and causing transmission failure. Furthermore, the elastic force of the elastic element can always push the connecting arm to clamp the ice-crushing chamber in the axial direction. This, in conjunction with the transmission screw, makes the clamping of the connecting arm more stable and reliable. At the same time, it can also make the keyed connection between the sliding shaft and the ice-crushing blade more secure.

[0011] In one illustrative embodiment of the ice-crushing device, the device further includes a lead screw motor that drives the transmission lead screw to rotate. The connecting arm is also equipped with a trigger rod, the extension direction of which is parallel to the axial direction. The ice-crushing device also includes a micro switch, which is fixedly mounted on the frame. When the connecting arm reaches the disengaged and / or engaged position, it can drive the trigger rod to touch the micro switch, causing the micro switch to output a stop signal that controls the lead screw motor to stop working. This design of the trigger rod and micro switch ensures that the transmission lead screw drives the connecting arm to move only within a permissible axial distance. Beyond this range, the trigger rod will touch the micro switch to stop the continuous movement of the connecting arm. This prevents the connecting arm from excessively clamping and fixing the ice-crushing chamber, thus avoiding damage to the ice-crushing chamber, and also preventing damage to the sliding shaft and drive shaft caused by the connecting arm, ensuring the safety of the device during operation.

[0012] In one illustrative embodiment of the ice-crushing device, the ice-crushing chamber is tilted and fixed to the frame, and includes an ice inlet with a top opening and an ice outlet with a bottom opening. The ice-crushing blade is a roller structure, and an ice-crushing channel is formed between the ice-crushing blade and the inclined inner wall of the ice-crushing chamber, connecting the ice inlet and the ice outlet. The inner wall of the ice-crushing chamber forming the ice-crushing channel is provided with several ice-crushing teeth arranged at intervals, and the ice-crushing blade has several rows of ice-crushing blades arranged circumferentially, each row of ice-crushing blades being able to rotate and pass through the gaps between the ice-crushing teeth. This ice-crushing channel design provides ample space for ice to be crushed, and the cooperation between the ice-crushing teeth on the inner wall of the ice-crushing channel and the ice-crushing blades ensures that the user can obtain ice particles of uniform size.

[0013] In one illustrative embodiment of the ice crushing device, a pair of hollow support rods are fixedly mounted on the frame. A transmission screw passes through one of the support rods and rotates relative to the support rod. The outer wall of the ice crushing chamber is provided with a hook and abutment. The hook is attached to one of the support rods, and the abutment abuts against the other support rod. This support rod design, on the one hand, works with the hook and abutment of the ice crushing chamber to ensure that the ice crushing chamber is stably mounted on the frame, preventing it from detaching during operation and facilitating subsequent disassembly. On the other hand, the interior of the support rods also provides space for the transmission screw, integrating the support rods and the transmission screw into one unit, reducing the space occupied inside the device and improving the overall compactness of the device structure.

[0014] In one illustrative embodiment of the ice-crushing device, the device further includes a follower arm, which is axially opposite to the connecting arm at both ends of the ice-crushing chamber. A rotating transmission screw can also drive the follower arm to move axially, cooperating with the connecting arm to clamp and disengage the ice-crushing chamber. This design allows the connecting arm, in conjunction with the follower arm, to achieve double-sided clamping and fixation on both sides of the ice-crushing chamber, making the disassembly of the ice-crushing chamber more convenient.

[0015] In one illustrative embodiment of the ice crushing device, the ice crushing chamber includes a main body and a detachable extension chamber connected to the main body, the extension chamber having an ice inlet. This structural design facilitates cleaning, disinfection, and maintenance of the ice crushing chamber; the operator can disassemble the chamber into two parts and clean each part sequentially. Furthermore, when a large amount of ice is needed clinically, the extension chamber increases the distance from the ice inlet to the ice crushing channel. This allows the operator to place a large amount of ice into the inlet while preventing splashing caused by excessive ice volume; the extension chamber acts as a buffer against ice during the crushing process.

[0016] In one illustrative embodiment of the ice crushing device, the ice crushing chamber body includes a pair of end caps, which are detachably mounted at both ends of the ice crushing channel. This end cap design allows the operator to access the ice crushing blades inside the ice crushing chamber body after it has been removed from the device, thereby enabling maintenance and sterilization of the ice crushing blades. Furthermore, the end cap design facilitates the clamping and securing of the ice crushing chamber by the connecting arm.

[0029] like Figure 1The diagram shows the internal structure of the ice crushing device. In the actual product, the ice crushing device also has a shell (not shown in the diagram) on the outside. The shell protects the internal structure of the ice crushing device. Fixing frames 80 and fixing plates 90 are installed between the main internal structures to ensure that each main structure is stably fixed inside the device, ensuring the smooth operation of the entire device. For clarity, the fixing frames 80 and fixing plates 90 are omitted, resulting in the diagram shown below. Figure 2 The diagram shown is a structural schematic.

[0030] like Figure 2 , combined Figure 3 As shown, the ice crushing device includes a frame 10, an ice crushing chamber 20, a drive motor 30, a transmission screw 40, and a connecting arm 50. The ice crushing chamber 20 is detachably mounted on the frame 10, and an ice crushing blade 22 is installed inside the ice crushing chamber 20. The drive motor 30 is fixed to the frame 10 and includes a drive shaft 32 and a sliding shaft 34 that drives the drive shaft 32 in the axial direction A. The sliding shaft 34 can slide and switch between an engaged position and a disengaged position relative to the drive shaft 32 along the axial direction A, thereby enabling the sliding shaft 34 to connect or disconnect from the ice crushing blade 22 inside the ice crushing chamber 20. In other words, the drive motor 30 can connect to the ice crushing blade 22 via the drive shaft 32 and the sliding shaft 34, and drive the ice crushing blade 22 to rotate relative to the ice crushing chamber 20.

[0031] The transmission screw 40 is rotatably mounted on the frame 10. In the actual product, the transmission screw 40 is a long rod located on the back of the ice crusher 20, and one end of the transmission screw 40 has an external thread. The connecting arm 50 has a transmission part 52 that can be threadedly connected to the transmission screw 40. Figure 3 As shown, the transmission part 52 is a through hole on the connecting arm 50, and a screw nut that cooperates with the transmission screw 40 is installed in the through hole. The transmission screw 40 passes through the screw nut in the transmission part 52. When the transmission screw 40 rotates, the connecting arm 50 moves relative to the transmission screw 40 under the cooperation of the screw nut. The direction of rotation of the transmission screw 40 is different, and the direction of movement of the connecting arm 50 is also different. For example, if the transmission screw 40 rotates clockwise, the connecting arm 50 moves in the axial direction A. If the transmission screw 40 moves counterclockwise, the connecting arm 50 moves in the opposite direction to the axial direction A. Of course, those skilled in the art will understand that the relationship between the rotation direction of the transmission screw 40 and the movement direction of the connecting arm 50 can be set as needed.

[0032] The connecting arm 50 also includes a clamping part 54 that can be connected to the bearing of the sliding shaft 34, such as Figure 3As shown, the clamping part 54 is a hollow cover with a bearing inside. The sliding shaft 34 passes through the cover in the axial direction A and is connected to the bearing inside the cover, so that the connecting arm 50 can drive the sliding shaft 34 to move while the sliding shaft 34 can also rotate relative to the clamping part 54 of the connecting arm 50.

[0033] The specific working process of the ice crushing device is as follows: (1) such as Figure 4 As shown, during normal operation of the ice crushing device, the clamping part 54 of the connecting arm 50, i.e., the cover, is stably clamped and connected to one side of the ice crushing chamber 20. The sliding shaft 34 inside the cover is in the engagement position at this time, i.e., it is connected to the ice crushing blade 22 of the ice crushing chamber 20. Then, the drive motor 30 drives the drive shaft 32 to rotate, and the drive shaft 32 drives the sliding shaft 34 to rotate inside the clamping part 54, thereby driving the ice crushing blade 22 to rotate inside the ice crushing chamber 20, so that the ice crushing device can perform ice crushing work.

[0034] (2) When it is necessary to disassemble, repair, and disinfect the ice-crushing blade 22, stop the operation of the ice-crushing device, such as... Figure 5 As shown, the operator controls the transmission screw 40 to start rotating. The rotating transmission screw 40 drives the connecting arm 50 to move in the direction shown by arrow B in the figure. Then, the clamping part 54 of the connecting arm 50 disengages from the ice crushing chamber 20. The connecting arm 50 drives the sliding shaft 34 inside it to move relative to the fixed drive shaft 32 in the direction of arrow B, so that the sliding shaft 34 reaches a disengaged position, that is, it is disconnected from the ice crushing blade 22 in the ice crushing chamber 20. At this time, the ice crushing chamber 20 can be removed from the device, and the ice crushing blade 22 can be maintained.

[0035] (3) After maintenance, the ice crushing chamber 20 is placed back into the device. The operator controls the transmission screw 40 to rotate in the reverse direction. The reverse-rotating transmission screw 40 drives the connecting arm 50 along the direction of rotation. Figure 5 Moving closer to the ice crushing chamber 20 in the opposite direction to arrow B, the connecting arm 50 drives its internal sliding shaft 34 to move closer to the ice crushing chamber 20 relative to the fixed drive shaft 32 in the opposite direction to arrow B. When the clamping part 54 of the connecting arm 50 moves to a position that can clamp and fix the ice crushing chamber 20, the sliding shaft 34 reaches an engagement position, that is, the sliding shaft 34 is reconnected to the ice crushing blade 22, so that the drive motor 30 drives the rotation of the ice crushing blade 22 again.

[0036] During clinical surgical procedures, to ensure that the ice particles used meet sterility requirements, the internal components of the ice crushing device, especially the ice crushing blades that come into direct contact with the ice, need to be regularly disinfected and sterilized. The device itself also requires routine maintenance and repair. This necessitates that the ice crushing blades be easily disassembled and reassembled. However, in the design of existing ice crushing devices, to ensure the drive motor can stably rotate the ice crushing blades, the internal components are interdependent and tightly connected. Often, disassembling one ice crushing blade requires disassembling the surrounding components, greatly increasing the difficulty of disassembling the ice crushing blades and making disinfection and maintenance extremely inconvenient. Furthermore, the device contains many precision parts; if parts are lost during disassembly or incorrectly installed during reassembly, it could significantly affect the stable operation of subsequent components.

[0037] Therefore, the design of this application uses the movement of the connecting arm 50 to connect and disconnect the sliding shaft 34 from the ice-crushing blade. The connecting arm 50 itself can also switch between clamping and releasing the ice-crushing chamber 20. This not only ensures that the drive motor 30 can smoothly drive the rotation of the ice-crushing blade 22, but also greatly simplifies the assembly relationship between the drive motor 30 and the ice-crushing blade 22. This allows the ice-crushing blade 22 to easily break free from the control of the drive motor 30, enabling rapid disassembly and facilitating its daily maintenance and sterilization. Furthermore, during post-repair reassembly, since the participation of various precision parts is not required, the connecting arm 50 can drive the sliding shaft 34 to achieve rapid and precise alignment and reset between it and the ice-crushing blade 22 in the axial direction, ensuring the reliability of the connection. The connecting arm 50 can also clamp and fix the ice-crushing chamber 20, ensuring its stable placement on the frame and guaranteeing the smooth operation of the subsequent ice-crushing device.

[0038] like Figure 6 As shown, the drive shaft 32 also has a insertion cavity 321, which is arranged along the axial direction A. The inner wall of the insertion cavity 321 is provided with a keyway 322 arranged along the axial direction A. The keyway 322 can be an elongated groove. The sliding shaft 34 has a sliding end that is slidably connected to the drive shaft 32. The outer wall of the sliding end is provided with a connecting key 342 that can be keyed to the keyway 322. The connecting key 342 can be a cuboid connecting key that can cooperate with the cuboid groove, allowing the connecting key 342 to slide along the keyway 322 along the axial direction A. This connection method allows the sliding shaft 34 to slide relative to the drive shaft 32 while also enabling the drive shaft 32 to stably drive the sliding shaft 34 to rotate in the same direction, thereby causing the drive shaft 32 to drive the rotation of the ice-crushing blade 22.

[0039] like Figure 3As shown, in one illustrative embodiment of the connection between the sliding shaft 34 and the ice-crushing blade 22, the sliding shaft 34 has a connecting end opposite to the sliding end. The outer wall of the connecting end is provided with a first spline 346. The outer side of the end face of the ice-crushing chamber 20 is provided with a second spline 226 that can drive the ice-crushing blade 22 to rotate. The clamping part 54 of the connecting arm 50 is provided with a linkage sleeve 542. Specifically, the linkage sleeve 542 can be disposed inside the clamping part 54, and the linkage sleeve 542 can rotate relative to the clamping part 54. The two ends of the linkage sleeve 542 can be connected to the first spline 346 and the second spline 226 respectively. This linkage bushing 542, in conjunction with the spline connection, allows the sliding shaft 34 to achieve a firm fit with the ice crushing blade 22, ensuring the tightness of the connection and guaranteeing that the sliding shaft 34 can stably drive the ice crushing blade 22 to rotate. On the other hand, the design of the linkage bushing 542 also allows the sliding shaft 34 and the ice crushing chamber 20 to quickly and accurately dock after reinstallation, thereby ensuring the normal operation of the equipment in the future.

[0040] like Figure 3 As shown, the ice crushing device also includes an elastic element 344, which is a spring structure. One end of the elastic element 344 abuts against the drive shaft 32, and the other end abuts against the first spline 346. The elastic element 344 can provide elastic force to the sliding shaft 34. When the transmission screw 40 drives the connecting arm 50 to clamp and fix the ice crushing chamber 20, the elastic force can always push the sliding shaft 34 to maintain a key connection with the linkage sleeve 542 during the movement of the sliding shaft 34 relative to the drive shaft 32, thereby preventing the sliding shaft 34 from falling out of the linkage sleeve 542 and causing transmission failure, which would affect the ice crushing effect. Furthermore, when the transmission screw 40 drives the connecting arm 50 to clamp and fix the ice crushing chamber 20, if the connection between the connecting arm 50 and the transmission screw 40 becomes loose, the connecting arm 50 will easily detach from the clamping of the ice crushing chamber 20. The elastic element 344 ensures that its elastic force can always push the connecting arm 50 to clamp the ice crushing chamber 20 in the axial direction A, and cooperates with the transmission screw 40 to make the clamping of the connecting arm 50 more stable and reliable. At the same time, it can also push the key connection between the sliding shaft 34 and the ice crushing blade 22 to be more secure.

[0041] like Figure 4 , Figure 5 As shown, the ice-crushing device also includes a screw motor 42 that drives the transmission screw 40 to rotate, combined with... Figure 3As shown, the connecting arm 50 is also equipped with a trigger rod 522. The connecting arm 50 can drive the trigger rod 522 to move. The extension direction of the trigger rod 522 is parallel to the axial direction A, that is, parallel to the moving direction of the connecting arm 50. The ice crushing device also includes a micro switch 60, which is fixedly installed on the frame 10. When the connecting arm 50 drives the sliding shaft 34 to the clutch position, the trigger rod 522 touches the micro switch 60, causing the micro switch 60 to output a stop signal that can control the lead screw motor 42 to stop working. Then the transmission lead screw 40 stops rotating and the connecting arm 50 stops moving. Alternatively, when the connecting arm 50 drives the sliding shaft 34 to the engagement position, the trigger rod 522 can also trigger the micro switch 60 to stop the lead screw motor 42. Of course, those skilled in the art will understand that there can be two micro switches 60, one corresponding to the engagement position to stop the transmission lead screw 40 from rotating and the other corresponding to the clutch position, or there can be only one micro switch, corresponding to only one of the two positions. Furthermore, the trigger rod 522 and the micro switch 60 can be either contact-type or non-contact-type. For example, if the trigger rod 522 is equipped with an infrared sensor, the micro switch can be equipped with an infrared sensor. This design of the trigger rod and micro switch ensures that the transmission screw 40 drives the connecting arm 50 to move only within the allowable axial distance. If the movement exceeds this range, the trigger rod 522 will trigger the micro switch 60 to stop the continuous movement of the connecting arm 50. This prevents the connecting arm 50 from excessively clamping and fixing the ice crushing chamber 20 and causing damage to it, and also prevents the connecting arm 50 from causing damage to the sliding shaft 34 and the drive shaft 32, thus ensuring the safety of the device during operation.

[0042] like Figure 7 As shown, combined with Figure 2 The ice crushing chamber 20 is fixed at an angle to the frame 10 and includes an ice inlet 232 with an opening at the top and an ice outlet 234 with an opening at the bottom. The ice crushing blade 22 is a roller structure. The ice crushing blade 22 and the inclined inner wall of the ice crushing chamber 20 form an ice crushing channel 202 that connects the ice inlet 232 and the ice outlet 234. In actual use, large ice blocks can enter the ice crushing channel 202 through the ice inlet 232. The inner wall of the ice crushing chamber 20 that forms the ice crushing channel 202 is provided with several ice crushing teeth 204 arranged with gaps. The ice crushing blade 22 is provided with several rows of ice crushing blade heads 222 along its circumference. Each row of ice crushing blade heads 222 can rotate through the gaps between the several ice crushing teeth 204. The cooperation between the two can fully crush the large ice blocks that enter and discharge them from the ice outlet 234.

[0043] like Figure 8 , combined Figure 3As shown, the frame 10 is fixedly equipped with a pair of hollow support rods 12, which are arranged in parallel. A transmission screw 40 passes through the interior of one of the support rods 12, and the transmission screw 40 rotates relative to the support rod 12. The outer wall of the ice crushing chamber 20, specifically on the back of the ice crushing chamber 20, is provided with a hook part 205 and a stop part 207, as shown. Figure 8 As shown, the hook 205 is hung on one of the support rods 12, while the abutment 207 abuts against the other support rod 12. This design of the support rod 12 allows the ice crushing chamber 20 to be stably set on the frame 10, preventing it from falling off during operation and facilitating subsequent disassembly. On the other hand, the inside of the support rod 12 can also provide space for the transmission screw 40. Integrating the support rod 12 and the transmission screw 40 into one place reduces the space occupied inside the device and improves the compactness of the overall structure of the device.

[0044] like Figure 9 As shown, in one illustrative embodiment of the ice-crushing device, the device further includes a follower arm 70. The follower arm 70 and the connecting arm 50 are disposed opposite each other at both ends of the ice-crushing chamber 20 in the axial direction A. At this time, both ends of the transmission screw 40 include threaded structures, and the connecting arm 50 and the follower arm 70 are respectively connected to the threaded structures at both ends of the transmission screw 40. Figure 9 As indicated by the two arrows, when the drive screw 40 rotates, it drives the connecting arm 50 and the follower arm 70 to move in opposite directions, meaning that both of them disengage from the ice crushing chamber 20. Due to the design of the support rod 12, the ice crushing chamber 20 will not fall off when it is disengaged. When the drive screw 40 rotates in the opposite direction, it drives the connecting arm 50 and the follower arm 70 to move in the direction of clamping the ice crushing chamber 20. This design allows the follower arm 70 to work with the connecting arm 50 to achieve double-sided clamping and fixation on both sides of the ice crushing chamber 20, making it easier to disassemble the ice crushing chamber 20.

[0045] like Figure 9 As shown, in one illustrative embodiment of the ice crushing chamber 20, the ice crushing chamber 20 includes a main body 26 and a detachable extension chamber 28 connected to the main body 26. The extension chamber 28 is provided with an ice inlet 232. This detachable structure design of the ice crushing chamber 20 facilitates cleaning, disinfection, and maintenance, allowing the operator to disassemble the ice crushing chamber 20 into two parts for sequential cleaning. Furthermore, when a large amount of ice is needed clinically, the distance from the ice inlet 232 to the ice crushing channel 202 is increased by connecting the main body 26 to the extension chamber 28. This allows the operator to place a large amount of ice into the ice inlet 232 while preventing splashing caused by excessive ice volume; in other words, the extension chamber 28 provides some obstruction to the ice during the crushing process.

[0046] like Figure 9 As shown, in another illustrative embodiment of the ice crushing chamber 20, the ice crushing chamber body 26 includes a pair of end caps 264. The pair of end caps 264 are detachably disposed at both ends of the ice crushing channel 202, so that after the ice crushing chamber body 26 is removed from the device, the operator can again obtain the ice crushing blade 22 inside the ice crushing chamber body 26 by removing the end caps 264 on both sides of the ice crushing chamber body 26, thereby realizing the maintenance and disinfection of the ice crushing blade 22. In addition, the design of the end caps 264 also facilitates the clamping and fixing of the connecting arm 50 to the ice crushing chamber 20.
