Description

Technical Field

[0001] The present invention relates to the technical field of blood sample storage, and more specifically, to an ice water Bath test tube box and its control system. Background Art

[0002] The main function of the renin-angiotensin system (RAS) is to regulate human blood pressure, water, electrolytes and maintain the stability of the human body's internal environment. The renin-angiotensin system exists in the circulatory system as well as in tissues such as vascular walls, heart, central nervous system, kidneys and adrenal glands, and participates in the regulation of target organs. Renin is a proteolytic enzyme secreted by juxtaglomerular cells. After entering the blood circulation, it reacts with angiotensinogen formed in the liver to form angiotensin I, which can be converted into angiotensin II. It has a strong vasoconstriction effect and can stimulate the adrenal cortex to secrete aldosterone, causing water and sodium retention, thus leading to increased blood pressure, which is one of the pathogenesis of hypertension. Renin-angiotensin generally needs to be checked in the hospital by drawing blood with the cooperation of a doctor. The conditions for measuring renin activity in plasma are relatively harsh. After blood specimens are collected, they need to be stored in an ice water bath and sent for testing immediately to ensure the accuracy of the test, otherwise the composition will change, making the test results have no reference value.

[0003] In the prior art, a common practice is to put a transparent bag on a test tube containing a blood sample and put it into a disposable cup filled with ice and water. However, in actual work, medical staff may forget to put on the transparent bag and directly put the test tube into the cup filled with ice and water, causing the barcode on the surface of the test tube to get wet, blurred, or fall off. In addition, the ice in the disposable cup may be accidentally knocked over, causing other items on the table or the ground to get wet, which may also cause accidents such as people falling and biosafety spills. Therefore, in response to this defect, the Chinese patent document (authorization announcement number CN221477883U, application date 2023-11-21, authorization announcement date 2024-08-06) discloses an ice bath specimen transport device, including an outer shell and an inner cylinder, the outer shell is hollow inside and open at the upper end, the inner cylinder is open at the upper end and has a placement groove for placing test tubes inside, a boss is provided at one end of the inner cylinder near the opening, the lower end of the inner cylinder is inserted into the outer shell from the open end of the outer shell and is detachably connected to the outer shell, the boss is clamped on the upper end face of the outer shell, and closes the upper end opening of the outer shell, and a closed cavity for perfusing refrigerated liquid is formed between the inner cylinder and the outer shell; the detachably connected inner cylinder and outer shell facilitate cleaning and disinfection of the device, and it can be reused to reduce the cost of use; at the same time, the boss provided on the inner cylinder can close the opening at the upper end of the surgery, forming a closed cavity between the inner cylinder and the outer shell, which can prevent the refrigerated liquid perfused in the closed cavity from overflowing, resulting in higher temperature and shortened refrigeration time. The ice bath specimen transport device is only suitable for single transport, not for individual blood sample transport, and the ice bath specimen transport device needs to add refrigeration liquid, and the use of refrigeration liquid increases the storage cost of the hospital. In actual work, medical staff are very busy and cannot observe the temperature of the refrigeration liquid in time. Replacing the refrigeration liquid may cause changes in the blood sample composition, and the accuracy of the test cannot be guaranteed, making the test results have no reference value.

DETAILED DESCRIPTION

[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0021] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0022] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0023] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0024] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0025] Embodiment 1 In an alternative embodiment, referring to Figure 1-Figure 9The ice-water bath test tube box provided in this embodiment includes a box body 10, and a box cover 20 is detachably connected to the box body 10. Specifically, the box body 10 is configured as an upper box body 101 and a lower box body 102 that are detachably connected; a water storage tank 11 is provided in the box body 10, and a freezing rack 70 is detachably connected to the bottom of the water storage tank 11. A test tube rack 12 is provided above the water storage tank 11. A temperature control module and a liquid level adjustment module are provided in the water storage tank 11. The temperature control module is used to control and feedback the temperature of the ice-water mixture; the liquid level adjustment module is used to adjust the liquid level of the ice-water mixture in the water storage tank 11; the temperature control module and the liquid level adjustment module are electrically connected to the controller 60 respectively.

[0026] It is understandable that there are multiple ice cubes frozen in the freezing rack 70, the freezing rack 70 is fixed in the water storage tank 11, water is injected into the water storage tank 11 and mixed with the ice cubes in the freezing rack 70 to form an ice-water mixture, the liquid level of the ice-water mixture in the water storage tank 11 is adjusted by the liquid level adjustment module, and the test tubes (blood samples are stored in the test tubes) in the test tube rack 12 are refrigerated and stored; when the ice cubes in the ice-water mixture are melted, the temperature control module detects that the temperature of the ice-water mixture is higher than the refrigeration temperature, and the controller 60 controls the temperature control module to refrigerate the ice-water mixture so that the ice-water mixture reaches the refrigeration temperature, and the test tubes in the test tube rack 12 are refrigerated and stored. The liquid level adjustment module can detect the liquid level of the ice-water mixture in the water storage tank 11 and control the liquid level of the ice-water mixture in the water storage tank 11.

[0027] It should be noted that the box body 10 is made of transparent organic glass that is resistant to low temperatures and shatterproof, so that the state and liquid level of the ice-water mixture can be easily observed; the ice-water mixture placed in the water tank 11 is used to maintain the stability of the blood sample; the liquid level adjustment module is used to adjust the liquid level of the ice-water mixture in the water tank 11 to prevent the water level of the ice-water mixture from being too low so that the blood sample cannot be located in the ice-water mixture, affecting the preservation of the blood sample. The box body 10 is detachably connected to the box cover 20, and the easy-to-open box cover 20 can reduce the working time of medical staff and improve work efficiency; the box cover 20 is in contact with the test tube to prevent the test tube from moving due to shaking and bumping during the inspection process, so that the blood sample in the test tube is always in ice water.

[0028] In order to prevent the barcodes pasted on the test tubes on the test tube rack 12 from getting wet, blurred, or falling off. Figure 5-Figure 9 In an optional embodiment, a partition 30 is further provided in the box body 10, and the partition 30 is used to limit the height of the ice-water mixture in the water storage tank 11; the test tube rack 12 includes a main body 121 and a tube body 122 fixed on the main body 121; and a tube hole 31 adapted to the tube body 122 is opened on the partition 30.

[0029] It is understandable that the test tube rack 12 includes a main body 121 and a tube body 122 fixed on the main body 121. The tube body 122 is adapted to the test tube for storing the blood sample. The test tube can be just stuck in the tube body 122, and the test tube fits the inner wall of the tube body 122 to ensure that the blood sample in the test tube meets the storage temperature requirements; in order to ensure the storage temperature of the blood sample, the tube body 122 is made of a metal with good thermal conductivity, preferably a thin aluminum metal material. The test tube placed in the tube body 122 does not directly contact the ice-water mixture, so as to avoid the barcode pasted on the surface of the test tube from getting wet, blurred, or falling off. The connection between the test tube rack 12 and the box 10 is a sealed connection. When the ice-water mixture is shaken, the test tube rack 12 can isolate the ice-water mixture to prevent the ice-water mixture from entering the top of the test tube rack 12.

[0030] The partition 30 is located below the test tube rack. The partition 30 is provided with a tube hole 31 that matches the tube body 122 of the test tube rack 12, so that the tube body 122 can pass through the tube hole 31 without affecting the contact between the tube body 122 of the test tube containing the blood sample and the ice-water mixture. The matching tube hole 31 and the tube body 122 are sealed and connected, which can isolate the ice-water mixture when the ice-water mixture is shaken, prevent the ice-water mixture from entering the partition 30, and further prevent the ice-water mixture from entering the test tube rack 12. The partition 30 and the test tube rack 12 have multiple layers of protection to prevent the ice-water mixture from entering the test tube rack 12, and prevent the barcodes pasted on the surface of the test tubes on the test tube rack 12 from getting wet, blurred, or falling off.

[0031] In actual use, in order to meet the storage time of blood samples and extend the use time of ice-water mixture, the amount of ice used is more than cold water. Figure 4 , Figure 7-Figure 9 , Figure 11-Figure 12 In an optional embodiment, the box body 10 includes a detachably connected upper box body 101 and a lower box body 102, the test tube rack 12 and the partition 30 located below the test tube rack 12 are fixed in the upper box body 101, and the freezing rack 70 is fixed in the lower box body 102; the freezing rack 70 includes a support 71 and a freezing plate 72 fixed on the support 71 at intervals, the horizontal cross-sectional area of ​​the freezing plate 72 increases from top to bottom, and the support 71 is detachably connected to the bottom of the water storage tank 11; a plurality of freezing grooves 73 are provided on the freezing plate 72, the freezing grooves 73 are inverted cones, and drainage grooves 74 are provided between the freezing grooves 73; a suction cup 75 is fixed at the bottom of the support 71, and a handle 15 is fixed at the top of the support 71.

[0032] It is understandable that the box body 10 is configured as a detachably connected upper box body 101 and a lower box body 102, so that the inner walls of the upper box body 101 and the lower box body 102 can be easily brushed and kept clean. The test tube rack 12 and the partition 30 are fixed in the upper box body 101, and the freezing rack 70 is fixed in the lower box body 102. The upper box body 101 and the lower box body 102 are sealed to prevent water leakage.

[0033] In order to freeze as many ice cubes as possible, multiple layers of freezing trays 72 are provided for freezing ice cubes; the sizes of the freezing trays 72 increase layer by layer from top to bottom, and cold water only needs to be injected into the freezing tray 72 on the top layer. After the freezing tray 72 on the top layer is filled with cold water, the cold water overflows from the freezing tray 72 on the top layer and flows into the freezing tray 72 on the next layer, and so on, until the freezing trays 72 on the freezing rack 70 are all filled with cold water; in order to prevent the ice cubes from being blocked by the freezing tray 72 on the upper layer when they leave the freezing tray 72, so that the ice cubes cannot float out of the freezing tray 72, the distance between two adjacent freezing trays 72 is greater than The height of the freezing plate 72 is convenient for the ice cubes on the freezing plate 72 to detach from the freezing plate 72 and float out when cold water is added to the water storage tank 11; in order to facilitate the ice cubes to detach from the freezing plate 72, the freezing grooves 73 on the freezing plate 72 are set to be inverted cones; in order to make each freezing groove 73 of the freezing plate 72 full of water, drainage grooves 74 are provided between the freezing grooves 73 for drainage, wherein the drainage grooves 74 are relatively small and very shallow grooves, which are easy to melt when encountering water. After cold water is added to the water storage tank 11, the ice cubes will not be connected together due to the ice in the drainage grooves 74 to form large ice blocks, which will affect the floating of the ice cubes.

[0034] The support 71 is detachably connected to the bottom of the water tank 11 to prevent the freezing rack 70 from tilting and falling when the box body 10 is moved, which affects the floating of ice cubes on the freezing rack 70 to the water surface. The suction cup 75 fixed at the bottom of the support 71 is adsorbed on the bottom surface of the inner wall of the lower box body 102, and a handle 76 is fixed on the top of the support 71 to facilitate the removal of the freezing rack 70.

[0035] In addition, when the ice cubes are separated from the freezing groove 73 of the freezing plate 72, it is inevitable that some of the ice cubes are blocked by the freezing plate 72 on the upper layer during the floating process, so that they cannot continue to float upward. Shaking the ice-water bath test tube box can change the position of most of the ice cubes blocked by the freezing plate 72 and float below the partition 30. At this time, due to the existence of the partition 30 and the freezing plates 72 on each layer, even if the ice-water bath test tube box is shaken, a small amount of ice cubes are still floating in layers in the water in the water storage tank 11. The small amount of ice cubes on multiple layers can better even out the water temperature, so that the temperature of the ice-water mixture in the water storage tank 11 is kept balanced, which is conducive to the preservation of blood samples.

[0036] It should be noted that the distance between the two freezing plates 72 can be selected according to actual needs. For example, when ice cubes need to be layered in the ice-water mixture to uniform the water temperature, the distance between the two freezing plates 72 is not greater than the height of the freezing tank 73, and the ice-water mixture is not shaken to make the ice cubes float to the surface of the ice-water mixture. The detachable connection method can also be a threaded connection. The bottom surface of the inner wall of the lower box body 102 is fixed with screws, and the bottom of the support 71 is provided with a screw hole. The screw is threadedly connected to the screw hole, so that the support 71 is detachably connected to the bottom of the water storage tank 11.

[0037] In actual work, medical staff are very busy. In order to reduce the working time of medical staff and improve work efficiency, the box body 10 and the box cover 20 are set to be connected in a convenient way for disassembly. Figure 1 , Figure 3-Figure 4 , Figure 8-Figure 9 In an optional embodiment, a lock hole 13 is symmetrically provided at one end of the inner wall of the box body 10 near the opening; a locking structure is fixed in the box cover 20, and the locking structure is detachably connected to the lock hole 13. The box cover 20 is connected and separated from the box body 10 by simply connecting and disassembling the locking structure and the lock hole 13. Specifically, a handle 21 is fixed on the upper top surface of the box cover 20, and the locking structure includes a button 24, a first return spring 25, a second return spring 26 and a lock rod 27; a movable groove 22 is provided on the handle 21, and the movable part of the button 24 is connected to the movable part of the lock rod 27 located in the handle 21 through the first return spring 25; the movable part of the lock rod 27 located in the handle 21 is connected to the movable groove 22 through the second return spring 26; a movable channel 23 is provided in the box cover 20, and the lock rod 27 can move in the movable channel 23, and the movable part of the lock rod 27 is detachably connected to the lock hole 13.

[0038] After the test tube is placed on the test tube rack 12, before the ice water bath test tube box is sent for testing, the box cover 20 is closed on the box body 10. Specifically, the movable part of the button 24 located outside the handle 21 is pressed, and the movable part of the button 24 moves into the movable groove 22, compressing the first return spring 25. The movable part of the lock rod 27 connected to the first return spring 25 is displaced by force, and the movable part of the lock rod 27 compresses the second return spring 26. The movement of the movable part of the lock rod 27 drives the movable part of the lock rod 27 to move in the movable channel 23, so that the movable part of the lock rod 27 is completely retracted into the movable channel 23; then Align the position of the moving part of the locking rod 27 with the locking hole 13, buckle the box cover 20 on the box body 10, release the button 24, the first return spring 25 and the second return spring 26 are no longer under force and are reset to a balanced state, the movable part of the locking rod 27 returns to its original position, driving the moving part of the locking rod 27 to return to its original position in the movable channel 23, so that the moving part of the locking rod 27 is inserted into the locking hole 13 on the box body 10, completing the closing and locking of the box cover 20 and the box body 10, and the box cover 20 is in contact with the test tube. During the inspection process, the test tube is prevented from moving due to shaking and bumping, so that the blood sample in the test tube is always in ice water.

[0039] Reference Figure 1-Figure 2In order to facilitate use and improve comfort during use, in an optional embodiment, a water scale line 14 is provided on the outer wall of the box body 10. By observing whether the ice-water mixture and the liquid surface coincide with the water scale line 14, it is determined whether water needs to be added or drained, so as to avoid the preservation effect of the blood sample being affected by too much or too little water. Because the density of ice is less than the density of water, no downward force is applied to the ice in the ice-water mixture, and the ice in the ice-water mixture will float on the water surface. The buoyancy of the ice may also lift up the test tube rack 12, causing the test tube rack 12 to be out of position and skewed. In order to make the ice-water mixture located below the water scale line 14, the partition 30 is fixed on the horizontal plane where the water scale line 14 is located, so that the height of the ice-water mixture does not exceed the water scale line 14.

[0040] The anti-skid piece 16 is fixed at the bottom of the box 10 and the body of the box 10. Because the temperature inside the box 10 filled with the ice-water mixture is lower than the temperature outside the box 10, when the water vapor outside the box 10 encounters the cold outer wall of the box 10, it will release heat and liquefy into liquid water, forming small water droplets attached to the outer wall of the box 10. In order to prevent the medical staff from slipping when picking up the box 10 with small water droplets attached, the anti-skid piece 16 is fixed at the bottom of the box 10 and the body of the box 10. The anti-skid piece 16 is made of a heat-insulating material to prevent the medical staff from getting frostbite when picking up the box 10. The anti-skid piece 16 is provided with tiny protrusions to increase the contact area when the medical staff picks up the box 10, so as to prevent the medical staff from slipping when picking up the box 10; the outer wall of the box 10 is connected with a handle 17, which is convenient for the medical staff to pick up the box 10 without getting frostbite.

[0041] When the ice bath test tube box is placed in room temperature for too long, the ice cubes may be about to melt or have melted, and the temperature of the ice-water mixture may not support the medical staff to send the ice bath test tube box for inspection. In order to maintain the stability of the sample and maintain the temperature of the ice-water mixture, in an optional embodiment, the temperature control module includes a refrigeration device 40 and a temperature detection device 41, and the refrigeration device 40 and the temperature detection device 41 are located in the water storage tank 11, and the refrigeration device 40 and the temperature detection device 41 are electrically connected to the controller 60. The temperature detection device 41 is used to detect the real-time temperature of the ice-water mixture. The controller 60 controls the temperature of the ice-water mixture according to the refrigeration temperature of the refrigeration device 40 determined according to the real-time temperature, ensures the temperature of the ice-water mixture, and maintains the stability of the sample. The ice cubes of the ice-water mixture melt, and the temperature of the ice-water mixture cannot be guaranteed, which is not enough to support the medical staff to send the ice bath test tube box for inspection. Using the temperature control module to refrigerate the ice-water mixture can avoid the cumbersome operation of adding ice water or ice cubes.

[0042] It should be noted that the refrigeration device 40 and the temperature detection device 41 are located in the upper box body 101 .

[0043] In order to accurately add cold water into the box 10 to avoid adding too little or too much cold water, refer to Figure 1, Figure 7 and Fig.13 In an optional embodiment, the liquid level regulating module includes a liquid level sensor 50, a water pump 51 located in the water storage tank 11, and a pipeline system connected to the water pump 51; the liquid level sensor 50 is fixed on the inner wall of the water storage tank 11, and the liquid level sensor 50 is used to detect the liquid level of the ice-water mixture; the pipeline system includes a main pipe 52, a branch pipe 53 connected to the main pipe 52, and a solenoid valve 54 connected to the main pipe 52 and the branch pipe 53; a through hole 18 is opened at one end of the box body 10 close to the opening, the main pipe 52 passes through the through hole 18, and the main pipe 52 passes through the through hole 18. The water inlet end of the pipe 52 is located outside the box body 10, and the water outlet end of the main pipe 52 is located in the water storage tank 11. The water outlet end of the main pipe 52 is connected to a water pump 51; the liquid level sensor 50, the water pump 51, the solenoid valve 54 and the controller 60 are electrically connected; a clamping member 19 is fixed to the outer wall of the box body 10, and the clamping member 19 is used to fix the water inlet end of the main pipe 52 located outside the box body 10 to the outer wall of the box body 10; a pipe sleeve 55 is fixed at the water inlet of the main pipe 52, and a sealing cover 56 is hinged on the pipe sleeve 55, and the sealing cover 56 covers the pipe sleeve 55.

[0044] It should be noted that the liquid level sensor 50 is located on the upper box body 101 , and the water pump 51 is located in the lower box body 102 . The water pump 51 can be taken out of the lower box body 102 along with the main pipe 52 .

[0045] Reference Figure 1 , Figure 7 There are two water scale lines 14, one is the lowest water scale line 14 at the bottom, and the other is the highest water scale line 14 at the top (the partition 30 is fixed on the horizontal plane where the highest water scale line 14 is located). Before use, fix the freezing rack 70 with frozen ice cubes in the box body 10, and before adding cold water, remove the main pipe 52 from the clamping member 19, open the sealing cover 56 on the pipe sleeve 55, and connect the water source; when adding cold water, the controller 60 controls the opening of the electromagnetic valve 54 on the branch pipe 53 and the main pipe 52 (the electromagnetic valve 54 on the branch pipe 53 or the electromagnetic valve 54 on the main pipe 52 can also be opened according to actual needs), so that cold water flows into the water storage tank 11 from the water inlet of the main pipe 52, until the liquid level sensor 50 detects that the liquid level of the ice-water mixture reaches between the lowest water scale line 14 and the highest water scale line 14, the controller 60 controls the closing of the electromagnetic valve 54 to stop water inflow. Then the water source is disconnected, the sealing cover 56 on the pipe sleeve 55 is closed, and the water pipe is fixed on the clamping member 19.

[0046] It should be noted that when too much cold water is added, the controller 60 controls the water pump 51 to start, opens the solenoid valve 54 on the main pipe 52, and discharges the excess cold water in the water storage tank 11. The through hole 18 is sealed with the main pipe 52; the outlet of the branch pipe 53 is located above the uppermost freezing plate 72 of the freezing rack 70; one end of the pipe sleeve 55 is connected to the main pipe 52, and the other end can be connected to the water source (and the faucet). When water is not added to the box body 10, the sealing cover 56 is closed to avoid keeping the box body 10 and the pipeline system clean.

[0047] It should be noted that when a water outlet is designed on the branch pipe 53, the size of the freezing tray 72 increases layer by layer from top to bottom, and cold water can be injected into the freezing tray 72 on the top layer. After the freezing tray 72 on the top layer is filled with cold water, the cold water overflows from the freezing tray 72 on the top layer and flows into the freezing tray 72 on the next layer, and so on, until the freezing trays 72 on the freezing rack 70 are all filled with cold water. A plurality of water outlets may also be designed on the branch pipe 53, and the branch pipe 53 extends from the center of the lower box body 102 to the box wall of the lower box body 102, and each water outlet corresponds to the topmost freezing plate 72, the second topmost freezing plate 72, ..., the bottommost freezing plate 72, and each water outlet is provided with a corresponding solenoid valve 54 for controlling the water outlet; at this time, the water outlet is controlled according to the water storage capacity of each layer of the freezing plate 72, and after one layer of the freezing plate 72 is filled, water is added to another layer of the freezing plate 72, so that each layer of the freezing plate 72 of the freezing rack 70 can be ensured to be full of water, thereby avoiding the situation where there is no water or little water in some freezing tanks 73, thereby meeting the requirements of freezing ice cubes.

[0048] Instructions for use: Before use, put cold water on the freezing rack 70, put the freezing rack 70 into a freezer to freeze the cold water on the freezing rack 70 into ice cubes.

[0049] When in use, the freezing rack 70 is adsorbed on the bottom surface of the inner wall of the lower box body 102 through the suction cup 75 and fixed in the lower box body 102, and the water pump 51 and the pipe system connected to the water pump 51 are placed in the lower box body 102 equipped with the freezing rack 70, and then the upper box body 101 and the lower box body 102 are connected to form the box body 10; Take it off from the clamping member 19, open the sealing cover 56 on the pipe sleeve 55, connect the water source, and the controller 60 controls the opening of the solenoid valve 54 on the branch pipe 53 and the main pipe 52 (the solenoid valve 54 on the branch pipe 53 or the solenoid valve 54 on the main pipe 52 can also be opened according to actual needs), so that cold water flows into the water storage tank 11 from the water inlet of the main pipe 52 until the liquid level sensor 50 detects that the liquid level of the ice-water mixture reaches between the lowest water scale line 14 and the highest water scale line 14, and the controller 60 controls the closing of the solenoid valve 54 to stop the water inflow. Then disconnect the water source, close the sealing cover 56 on the pipe sleeve 55, and fix the water pipe on the clamping member 19.

The movable part of the lock rod 27 connected to the first return spring 25 is displaced by force, and the movable part of the lock rod 27 compresses the second return spring 26. The movable part of the lock rod 27 moves and drives the movable part of the lock rod 27 to move in the movable channel 23, so that the movable part of the lock rod 27 is completely retracted into the movable channel 23; then align the position of the movable part of the lock rod 27 with the lock hole 13, and snap the box cover 20 onto the box body 10, release the button 24, the first return spring 25 and the second return spring 26 are no longer forced to reset to a balanced state, and the movable part of the lock rod 27 returns to its original position, driving the movable part of the lock rod 27 to return to its original position in the movable channel 23, so that the movable part of the lock rod 27 is inserted into the lock hole 13 on the box body 10, and the box cover 20 and the box body 10 are covered and locked. The box body 10 is shaken to make the ice cubes on the freezing shelf 70 separate from the freezing shelf 70 and float up.
