Description

Technical Field

[0001] The present invention relates to a medical device, and more particularly to a medical refrigerator. Background Art

[0002] In clinical work, it is often necessary to transfer drugs, blood samples, etc. At this time, the drugs, blood samples, etc. need to be placed in a refrigerator for low-temperature preservation. The current refrigerators are usually made of heat-insulating materials to form a box body, and the overall design is relatively simple. When in use, the entire lid needs to be opened, which will cause heat exchange between the inside and outside of the box body. When medical staff need to frequently take drugs and place blood samples, etc., it will further accelerate the loss of cold air inside the box and reduce the low-temperature preservation effect. Therefore, there is an urgent need for a refrigerator that can reduce the impact on the internal preservation environment during use. Summary of the Invention

[0003] The purpose of the present invention is to provide a medical refrigerator to solve one or more technical problems in the prior art and at least provide a beneficial alternative or create conditions.

[0004] The solution of the present invention to solve its technical problems is as follows:

[0005] A medical refrigerator, comprising: a base, forming a main cavity with an upward opening; an inner container, located in the main cavity, the inner container can rotate along the axis in the up and down direction in the main cavity, a rotating cap is provided on the top side of the middle part of the inner container, and the inner container forms a plurality of sub-cavities with upward openings around the rotating cap; a main lid, connected to the top side of the base, an avoidance opening is provided at the position of the main lid corresponding to the rotating cap, the rotating cap passes upward through the avoidance opening, and an operation opening is provided at the position of the main lid corresponding to one of the sub-cavities; a movable lid, detachably connected to the position of the main lid where the operation opening is located.

[0006] The technical solution has at least the following beneficial effects: Multiple sub - cavities for storing items respectively are formed inside the inner container. Refrigerants such as ice cubes for maintaining a low - temperature environment can also be directly placed into the multiple sub - cavities. The main cover is connected to the top side of the base and can cover and seal the multiple sub - cavities. At this time, one sub - cavity is exposed from the operation opening of the main cover. When the movable cover is connected to the main cover, the operation opening can be closed, thereby achieving the covering and protection of all sub - cavities. When items need to be taken from or placed into the sub - cavity, the movable cover can be opened, and operations can be performed on the sub - cavity exposed from the operation opening. At this time, the main cover also keeps the other sub - cavities covered and closed, effectively reducing the impact on the low - temperature preservation of other items. When it is necessary to switch to another sub - cavity for operation, force can be applied to the rotary cap. The whole inner container is driven to rotate by the rotary cap, so that another sub - cavity rotates to be directly opposite the operation opening. After completion, the movable cover can be re - connected to the main cover. In this way, the space inside the inner container is divided into multiple sub - cavities for independently taking and placing items. During use, only a single sub - cavity is exposed for operation, which can not only facilitate the classified management of different items but also reduce the impact on the low - temperature environment where other items are located, thereby improving the effect of low - temperature preservation of items.

[0007] As a further improvement of the above - mentioned technical solution, the inner container includes a bottom plate, a surrounding plate, and partition plates. The bottom plate is rotatably connected to the bottom side of the main cavity. The surrounding plate is connected to the outside of the bottom plate and extends around the bottom plate. A connecting column is connected to the top side of the middle part of the bottom plate. The partition plates are connected between the outside of the connecting column and the inside of the surrounding plate. A plurality of partition plates are arranged around the connecting column, and a sub - cavity is formed between two adjacent partition plates. The rotary cap is arranged on the top side of the connecting column. The bottom plate is used as a supporting and rotatably connecting supporting structure. The surrounding plate is arranged around the outside of the bottom plate and encloses an entire area for storing items above the bottom plate. The multiple partition plates connected between the surrounding plate and the connecting column further divide this area, thus forming multiple independent sub - cavities. Items can be respectively placed into the multiple independent sub - cavities. The multiple independent sub - cavities are respectively covered and closed by the main cover. When the user applies force to the rotary cap, the rotary cap can transmit the force to the connecting column, thereby driving the whole inner container to rotate.

[0008] As a further improvement of the above - mentioned technical solution, an outer - ring groove is arranged on the top side of the surrounding plate and extends around the center of the bottom plate. Receiving grooves are respectively arranged on the top sides of the multiple partition plates, and the multiple receiving grooves are respectively communicated with the outer - ring groove. The surrounding plate itself and the partition plates themselves can form a structure for storing refrigerants such as ice cubes. Specifically, an annular outer - ring groove is arranged on the top side of the surrounding plate, and receiving grooves are arranged on the top sides of the partition plates. During use, refrigerants such as ice cubes can be directly loaded into the outer - ring groove and the receiving grooves. In this way, the refrigerants such as ice cubes can be separated from the stored items, and a low - temperature preservation area can be formed outside the sub - cavity, making the temperature inside the sub - cavity a uniform low - temperature environment.

[0009] As a further improvement of the above technical solution, a sealing frame is connected to the bottom side of the rotating cap, and holes are formed on the sealing frame corresponding to the positions of the multiple sub-cavities, and a transmission shaft is connected to the bottom side of the sealing frame. A transmission groove is provided on the top side of the connecting column, and an inner ring groove extending around the transmission groove is provided on the top side of the connecting column. The multiple receiving grooves are respectively connected to the inner ring groove, and an outer ring rib inserted into the outer ring groove, a shielding rib inserted into the multiple receiving grooves, and an inner ring rib inserted into the inner ring groove are formed on the bottom side of the sealing frame. The transmission shaft is synchronously connected to the transmission groove, and a spring is provided between the bottom end of the transmission shaft and the bottom of the transmission groove. The spring has a tendency to lift the transmission shaft upward and press the sealing frame against the bottom side of the movable cover. The outer ring convex rib, the shielding convex rib and the inner ring convex rib formed on the bottom side of the sealing frame correspond to the positions of the multiple sub-cavities, and respectively form a structure for movement and enhanced sealing between the main cover and the multiple sub-cavities. When in use, the spring provides an upward lifting force to the transmission shaft, and the sealing frame at the top side end of the transmission shaft can be pressed to the bottom side of the main cover. At this time, the receiving sealing structure formed on the bottom side of the sealing frame corresponding to the multiple sub-cavities can effectively reduce the leakage of cold air in the sub-cavity to the outside, and improve the independent insulation effect of the multiple sub-cavities. When the inner tank needs to be rotated, the rotating cap is pressed down. At this time, the spring located between the bottom end of the transmission shaft and the storage groove is elastically compressed, and the sealing frame is pressed down. Move away from the main cover, and then rotate the rotating cap to drive the entire inner pot to rotate. Since the sealing frame is not in contact with the main cover, the inner pot can be rotated smoothly. After the sub-cavity is adjusted into place, the downward pressure of the rotating cap is removed. At this time, the elastic force of the spring recovery presses the transmission shaft upward, so that the sealing frame is pressed upward to the bottom side of the main cover, and the outer ring ribs, the shielding ribs and the inner ring ribs move upward in the outer ring groove, the storage groove and the inner ring groove accordingly, and remain inserted into the outer ring groove, the storage groove and the inner ring groove. In this way, the independent insulation effect of multiple sub-cavities can be improved during use, and when the inner pot needs to be rotated, the smoothness of the rotation of the inner pot can be improved.

[0010] As a further improvement of the above technical solution, a sealing groove is arranged around the avoidance on the bottom side of the main cover, and a sealing rib is arranged at a position corresponding to the sealing groove on the top side of the sealing frame, and the sealing rib is inserted into the sealing groove. By using the cooperation between the annular sealing rib and the sealing groove, a rotation connection limitation can be formed between the top side of the inner liner and the main cover, thereby improving the stability of the rotation of the inner liner, and when the inner liner is rotated, the sealing rib can remain inserted into the sealing groove, thereby reducing the escape of cold air from the gap between the main cover and the sealing frame, and further improving the effect of independent heat preservation of multiple sub-cavities.

[0011] As a further improvement of the above technical solution, a sealing strip is provided on the top side of the sealing rib. When the sealing rib and the sealing groove cooperate with each other, the sealing strip can fill the assembly gap between the two, thereby further improving the sealing performance of the sealing rib and the sealing groove.

[0012] As a further improvement of the above technical solution, the bottom side of the main cover is respectively provided with positioning grooves corresponding to the positions of the plurality of the partitions, and the top side of the sealing frame is respectively provided with universal wheels corresponding to the positions of the plurality of the positioning grooves, and the rolling ends of the plurality of the universal wheels are respectively accommodated in the plurality of the positioning grooves. In normal use, due to the upward lifting of the transmission shaft by the spring, the sealing frame is against the bottom side of the top cover, and at this time, the rolling ends of the plurality of universal wheels are respectively accommodated in the plurality of positioning grooves, which can limit the rotation of the inner liner. When the counter-rotating cap is pressed down, the sealing frame is driven to move down and away from the main cover, so that the rolling ends of the plurality of universal wheels move out of the positioning grooves, and the rotation restriction of the inner liner can be released. Then the rotating cap is rotated, and the rolling ends of the plurality of universal wheels can be against the bottom side of the main cover. At this time, the downward pressure of the counter-rotating cap can be removed, and the relative rotation of the sealing frame relative to the main cover can be realized by relying on the rolling ends of the universal wheels. When the next sub-cavity is facing the operation port, the rolling ends of the plurality of universal wheels are again accommodated in the plurality of positioning grooves, so that a sub-cavity can be accurately rotated to face the operation port, thereby improving the convenience of operation.

[0013] As a further improvement of the above technical solution, a heat preservation gap is formed between the outer side of the enclosure and the inner side of the main cavity. The heat preservation gap can be filled with heat preservation material or left empty directly. In this case, the temperature of the inner tank and the heat outside the base will not be directly exchanged through the contact between the enclosure and the base, further improving the heat preservation effect of the inner tank.

[0014] As a further improvement of the above technical solution, an annular slide rail is formed around the center of the bottom side of the bottom plate, and an annular slide groove is provided on the bottom side of the main cavity, and the annular slide rail and the annular slide groove are connected with each other. The bottom plate realizes rotation connection on the bottom side of the base through the mutual cooperation of the annular slide rail and the annular slide groove, and the stability of the bottom plate support can be improved, so that the bottom plate is more evenly stressed when rotating.

[0015] As a further improvement of the above technical solution, the main cover is detachably connected to the base. When in use, the main cover can be directly removed from the base, and multiple sub-cavities can be exposed at the same time, which is convenient for operation. When the inner tank needs to be maintained, the main cover can also be removed from the base, which is more flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Refer to Figure 1 、 Figure 2 and Figure 3, Medical refrigerator, including a base 100, an inner liner, a main cover 300 and a movable cover 400. Among them, a main cavity 110 with an upward opening is formed in the base 100; the inner liner is located in the main cavity 110, and the inner liner can rotate along the axis in the up and down direction in the main cavity 110. A rotating cap 210 is arranged on the top side of the middle part of the inner liner, and the inner liner forms a plurality of sub-cavities 260 with upward openings around the rotating cap 210; the main cover 300 is connected to the top side of the base 100, and an avoidance opening 310 is arranged at the position of the main cover 300 corresponding to the rotating cap 210, and the rotating cap 210 passes upward through the avoidance opening 310. An operation opening is arranged at the position of the main cover 300 corresponding to one of the sub-cavities 260; the movable cover 400 is detachably connected to the main cover 300 at the position of the operation opening. There are various detachable connection methods between the movable cover 400 and the main cover 300. It can be directly connected to the main cover 300 by a snap connection method. For the convenience of use, one side of the movable cover 400 can be hinged to the main cover 300. When the movable cover 400 is removed from the main cover 300, it is not necessary to remove the entire movable cover 400, and only the other side of the movable cover 400 needs to be separated from the main cover 300.

[0026] As can be seen from the above, a plurality of sub-cavities 260 for separately storing items are formed in the inner liner. Refrigerants such as ice cubes for maintaining a low-temperature environment can also be directly placed into the plurality of sub-cavities 260. The main cover 300 is connected to the top side of the base 100 and can cover and seal the plurality of sub-cavities 260. At this time, one sub-cavity 260 is exposed from the operation opening of the main cover 300. When the movable cover 400 is connected to the main cover 300, the operation opening can be closed, so as to realize the covering and protection of all sub-cavities 260. When it is necessary to take or place items into the sub-cavity 260, the movable cover 400 can be opened, and the exposed sub-cavity 260 can be operated from the operation opening. At this time, the main cover 300 also keeps the other sub-cavities 260 covered and closed, effectively reducing the influence on the low-temperature preservation of other items. When it is necessary to switch to another sub-cavity 260 for operation, force can be applied to the rotating cap 210, and the entire inner liner can be driven to rotate by the rotating cap 210, so that another sub-cavity 260 rotates to be directly opposite to the operation opening. After completion, the movable cover 400 can be reconnected to the main cover 300. In this way, the space inside the inner liner is divided into a plurality of sub-cavities 260 for independently taking and placing items. During use, only a single sub-cavity 260 is exposed for operation, which can not only facilitate the classification management of different items, but also reduce the influence on the low-temperature environment where other items are located, thereby improving the effect of low-temperature preservation of items.

[0027] A plurality of independent sub - cavities 260 are formed inside the inner container, and there are various structural forms. For example, the inner container includes a shell and a plate body, and the plate body directly divides the space inside the shell to form a plurality of sub - cavities 260. In order to conveniently connect the rotating cap 210 to the inner container and drive the whole to rotate, in this embodiment, the inner container includes a bottom plate 220, a surrounding plate 230 and a partition plate 240. The bottom plate 220 is rotatably connected to the bottom side of the main cavity 110, the surrounding plate 230 is connected to the outside of the bottom plate 220, the surrounding plate 230 extends around the bottom plate 220, a connecting column 250 is connected to the top side of the middle part of the bottom plate 220, the partition plate 240 is connected between the outside of the connecting column 250 and the inside of the surrounding plate 230, a plurality of partition plates 240 are arranged around the connecting column 250, and a sub - cavity 260 is formed between two adjacent partition plates 240. The rotating cap 210 is arranged on the top side of the connecting column 250. The bottom plate 220 is used as a supporting and rotatably connecting supporting structure. The surrounding plate 230 is arranged around the outside of the bottom plate 220, enclosing a whole area for storing items above the bottom plate 220. The plurality of partition plates 240 connected between the surrounding plate 230 and the connecting column 250 further divide this area, thus forming a plurality of independent sub - cavities 260. Items can be respectively placed into the plurality of independent sub - cavities 260, and the main cover 300 is used to respectively cover and close the plurality of independent sub - cavities 260. When the user applies force to the rotating cap 210, the rotating cap 210 can transmit the force to the connecting column 250, thereby driving the whole inner container to rotate.

[0028] Cooling media such as ice cubes for providing low temperature can be directly placed into the sub - cavity 260, and the items to be stored are also placed into the sub - cavity 260. At this time, it is easy to mix the two together, and there is also a problem that the temperature at the bottom of the sub - cavity 260 is relatively low or the temperature drops relatively fast, while the temperature at the top position is relatively high or the temperature drops relatively slowly. In order to separately store the two, in this embodiment, an outer - ring groove 231 is arranged on the top side of the surrounding plate 230, the outer - ring groove 231 extends around the center of the bottom plate 220, receiving grooves 241 are respectively arranged on the top sides of the plurality of partition plates 240, and the plurality of receiving grooves 241 are respectively communicated with the outer - ring groove 231. Naturally, the surrounding plate 230 and the plurality of partition plates 240 have a certain thickness, so that a groove structure for storing ice cubes can be formed inside. The surrounding plate 230 itself and the partition plate 240 itself can form a structure for storing cooling media such as ice cubes. Specifically, an annular outer - ring groove 231 is arranged on the top side of the surrounding plate 230, and a receiving groove 241 is arranged on the top side of the partition plate 240. During use, cooling media such as ice cubes can be directly loaded into the outer - ring groove 231 and the receiving grooves 241. In this way, the cooling media such as ice cubes and the stored items can be separated from each other, and a low - temperature storage area can be formed outside the sub - cavity 260, so that a low - temperature environment with uniform temperature is formed inside the sub - cavity 260.

[0029] In the above embodiments, the top side of the surrounding plate 230 can be directly adjacent to or tend to abut against the bottom side of the main cover 300 with the top side of the partition plate 240. When the inner container is rotated, due to the friction between the top side of the surrounding plate 230 and the top side of the partition plate 240 and the main cover 300, the smoothness of the rotation of the inner container will be affected. Therefore, in this embodiment, a sealing frame 211 is connected to the bottom side of the rotating cap 210. The sealing frame 211 is respectively formed with openings corresponding to the positions of the plurality of sub-cavities 260. A transmission shaft 212 is connected to the bottom side of the sealing frame 211. A transmission groove 251 is provided on the top side of the connecting column 250. An inner ring groove 252 extending around the transmission groove 251 is provided on the top side of the connecting column 250. The plurality of storage grooves 241 communicate with the inner ring groove 252 respectively. An outer ring rib 213 inserted into the outer ring groove 231, a shielding rib 214 inserted into the plurality of storage grooves 241, and an inner ring rib 215 inserted into the inner ring groove 252 are formed on the bottom side of the sealing frame 211. The transmission shaft 212 is synchronously connected to the transmission groove 251. That is, when the transmission shaft 212 rotates, it can drive the connecting shaft to rotate synchronously. The transmission shaft 212 can be designed as a polygonal prism. Correspondingly, the transmission groove 251 is also provided as a polygonal groove. A spring 218 is provided between the bottom end of the transmission shaft 212 and the groove bottom of the transmission groove 251. The spring 218 has a tendency to jack up the transmission shaft 212 and make the sealing frame 211 press against the bottom side of the movable cover 400.

[0030] In this embodiment, the sealing frame 211 uses the outer ring groove 231 and the storage groove 241 to provide space for movement and avoidance. Specifically, the outer ring rib 213, the shielding rib 214 and the inner ring rib 215 formed on the bottom side of the sealing frame 211 correspond to the positions of the multiple sub-cavities 260, and respectively form a structure for movement and enhanced sealing between the main cover 300 and the multiple sub-cavities 260. When in use, the spring 218 provides an upward lifting force to the transmission shaft 212, so that the sealing frame 211 at the top side end of the transmission shaft 212 can be pressed to the bottom side of the main cover 300. At this time, the receiving sealing structure formed on the bottom side of the sealing frame 211 corresponding to the multiple sub-cavities 260 can effectively reduce the leakage of cold air in the sub-cavity 260 to the outside, and improve the independent insulation effect of the multiple sub-cavities 260. When the inner tank needs to be rotated, the rotating cap 210 is pressed down. At this time, the bottom end of the transmission shaft 212 and the storage groove are connected. The spring 218 between 241 is elastically compressed, the sealing frame 211 moves down and away from the main cover 300, and then the rotating cap 210 is rotated to drive the entire inner tank to rotate. Since the sealing frame 211 is not in contact with the main cover 300, the inner tank can be rotated smoothly. After the sub-cavity 260 is adjusted to the right position, the downward pressure on the rotating cap 210 is removed. At this time, the elastic force of the spring 218 restores the transmission shaft 212 upward, so that the sealing frame 211 is pressed upward to the bottom side of the main cover 300, and the outer ring rib 213, the shielding rib 214 and the inner ring rib 215 correspondingly move upward in the outer ring groove 231, the storage groove 241 and the inner ring groove 252, and remain inserted into the outer ring groove 231, the storage groove 241 and the inner ring groove 252. In this way, the effect of independent insulation of multiple sub-cavities 260 can be improved during use, and when the inner tank needs to be rotated, the smoothness of the rotation of the inner tank can be improved.

[0031] When the sealing frame 211 is pressed down by the rotating cap 210, the sealing frame 211 is separated from the main cover 300. At this time, a gap will be generated between the sealing frame 211 and the main cover 300, and the cold air in the sub-cavity 260 will escape outward from the gap between the sealing frame 211 and the main cover 300. Therefore, in order to reduce the loss of cold air when the sealing frame 211 is pressed down, in this embodiment, a sealing groove is provided around the avoidance opening 310 on the bottom side of the main cover 300, and a sealing rib 216 is provided on the top side of the sealing frame 211 at a position corresponding to the sealing groove, and the sealing rib 216 is inserted into the sealing groove. By utilizing the cooperation between the annular sealing rib 216 and the sealing groove, a rotational connection limitation can be formed between the top side of the inner liner and the main cover 300, thereby improving the stability of the rotation of the inner liner. When the inner liner is rotated, the sealing rib 216 can remain inserted into the sealing groove, thereby reducing the escape of cold air from the gap between the main cover 300 and the sealing frame 211, and further improving the effect of independent insulation of multiple sub-cavities 260.

[0032] In practical applications, the inner and outer sides of the sealing rib 216 can be respectively set as inclined surfaces. The outer side surface of the sealing rib 216 is inclined from top to bottom in a direction away from the center, and the inner side surface of the sealing rib 216 is inclined from top to bottom in a direction away from the center. The entire sealing rib 216 is a trapezoidal structure with a small top and a large bottom. When the sealing rib 216 is separated from the sealing groove, the contact between the outer side wall of the sealing rib 216 and the inner side wall of the sealing groove can be effectively reduced, thereby improving the smoothness of the rotation of the sealing frame 211. When the sealing rib 216 is matched with the sealing groove, the tightness of the mutual matching between the two can also be improved.

[0033] Furthermore, a sealing strip is provided on the top side of the sealing rib 216. When the sealing rib 216 and the sealing groove cooperate with each other, the sealing strip can fill the assembly gap between the two, thereby further improving the sealing performance of the sealing rib 216 and the sealing groove.

[0034] In the above embodiment, when it is necessary to switch different sub-cavities 260 to face the operating port, the sub-cavity 260 and the operating port need to face each other. In order to facilitate the alignment of the two, in this embodiment, the bottom side of the main cover 300 is respectively provided with positioning grooves corresponding to the positions of the multiple partitions 240, and the top side of the sealing frame 211 is respectively provided with universal wheels 217 at the positions corresponding to the multiple positioning grooves. The rolling ends of the multiple universal wheels 217 are respectively accommodated in the multiple positioning grooves. In actual application, the universal wheel 217 includes a ball seat and a ball. The ball is installed in the ball seat. The ball has a part protruding from the ball seat. At this time, the part of the ball protruding from the ball seat is the rolling end. During normal use, the spring 218 pushes the transmission shaft 212 upward, so that the sealing frame 211 is against the bottom side of the top cover. At this time, the rolling ends of the multiple universal wheels 217 are respectively accommodated in the multiple positioning grooves, which can limit the rotation of the inner tank. When the swivel cap 210 is pressed down, the sealing frame 211 is driven to move down and away from the main cover 300, so that the rolling ends of the multiple universal wheels 217 move out of the positioning grooves, and the rotation restriction on the inner tank is released. Then the swivel cap 210 is rotated, and the rolling ends of the multiple universal wheels 217 can be against the bottom side of the main cover 300. At this time, the downward pressure of the swivel cap 210 can be removed, and the sealing frame 211 can be rotated relative to the main cover 300 by relying on the rolling ends of the universal wheels 217. When the next sub-cavity 260 is facing the operating port, the rolling ends of the multiple universal wheels 217 are re-accommodated in the multiple positioning grooves, so that a sub-cavity 260 can be accurately rotated to face the operating port, thereby improving the convenience of operation.

[0035] The outer side of the enclosing plate 230 can be adjacent to the inner side of the main cavity 110, or tend to abut against the inner side of the main cavity 110. At this time, heat exchange is likely to occur between the enclosing plate 230 and the side wall of the base 100, reducing the heat preservation performance of the inner container. Therefore, in this embodiment, a heat preservation gap 120 is formed between the outer side of the enclosing plate 230 and the inner side of the main cavity 110. The heat preservation gap 120 can be filled with heat preservation material, or directly left empty. At this time, the temperature of the inner container and the heat outside the base 100 will not directly exchange heat through the contact between the enclosing plate 230 and the base 100, further improving the heat preservation effect on the inner container.

[0036] As a specific embodiment in which the bottom plate 220 is rotatably connected to the bottom side of the main cavity 110, an annular slide rail is formed around the center of the bottom side of the bottom plate 220, and an annular slide groove 130 is provided on the bottom side of the main cavity 110. The annular slide rail and the annular slide groove 130 are connected in cooperation with each other. The bottom plate 220 is rotatably connected to the bottom side of the base 100 through the mutual cooperation of the annular slide rail and the annular slide groove 130, and the stability of the support for the bottom plate 220 can be improved, so that the force on the bottom plate 220 is more uniform when it rotates.

[0037] In some embodiments, the main cover 300 and the base 100 are detachably connected. For example, the main cover 300 can be fixed to the base 100 by means of snap connection, or fixed to the base 100 by means of screw connection. When in use, the main cover 300 can be directly removed from the base 100. At this time, multiple sub-cavities 260 can be exposed at the same time, which is convenient for operation. When the inner container needs to be maintained, the main cover 300 can also be removed from the base 100, making it more flexible and convenient to use. In practical applications, a main cover 300 made of transparent material can also be used, so that the items stored in the multiple sub-cavities 260 can be conveniently observed when the main cover 300 is connected to the base 100.

[0038] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
