Description

Technical Field

[0001] The utility model relates to the technical field of operation boxes, and particularly relates to an operation box with controllable temperature and humidity. Background Technique

[0002] During the hygroscopicity experiment of drugs, water absorption or water loss may occur. In order to ensure reliable comparison and high consistency of experimental results, therefore, the hygroscopicity of drugs should be ensured to be carried out under preset and stable environmental humidity conditions to avoid potential impacts of humidity changes on experimental results.

[0003] To ensure the accuracy of experimental results, drugs are usually placed in an operation box. However, for common operation boxes on the market, such as vacuum operation boxes, gas exchange operation boxes, and fully automatic operation boxes equipped with purification columns, there is a common step when placing drugs: the buckle lock must be unlocked first, then the box cover is opened, and only then can the drugs be placed. During this process, the opening of the box cover will cause the air inside the operation box to mix with the external air. Especially in summer, the dry external air flowing into the inside of the operation box will rapidly reduce its internal humidity.

[0004] Therefore, every time the box cover is closed after replacing the drugs, it is necessary to wait for the humidity inside the operation box to be adjusted back to the preset humidity range before starting the experiment. This waiting not only increases the total duration of multi-batch drug replacement experiments, but also significantly reduces the experimental efficiency and may cause unnecessary delays to the research process. Content of the Utility Model

[0006] For this reason, an object of the present utility model is to provide an operation box with controllable temperature and humidity, which can reduce the waiting time before the experiment while ensuring the accuracy of experimental results, thereby improving the experimental efficiency and ensuring the research process of the experiment.

[0029] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the following will further describe the solutions of the present invention. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0031] The following will describe the operation box with controllable temperature and humidity according to the embodiments of the present invention with reference to the drawings.

[0032] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 the humidity and temperature controllable operation box of the embodiment of the utility model may include a box body 1, a box cover 2, a plurality of plugging components 3, a rectangular pipe 4, a humidity control mechanism 5 and two humidity and temperature sensors 6.

[0033] Among them, the box cover 2 is pivotally connected to the box body 1. A plurality of through holes 20 are formed in the box cover 2, and the through holes 20 are detachably connected with plugging components 3. It can be understood that the pivotal connection can be realized in the form of a hinge or a pin shaft cooperating with a pin hole to make the box cover 2 pivotally connected to the box body 1, which can be selected according to the actual situation. Since the connection method is prior art, it will not be elaborated here.

[0034] It can be understood that by removing the plugging component 3, the hand of relevant personnel can extend into the box body 1 through the through hole 20 to operate the drugs in the box body 1. This design greatly improves the operation convenience, enabling users to easily open the box cover of the drugs for weighing, sub-packaging, and further moisture determination or other drug analysis and detection work that requires temperature and humidity control.

[0035] It should be noted that the box cover 2 described in this embodiment is made of a transparent material, so as to facilitate relevant personnel to operate the drugs in the rectangular pipe 4 and the box body 1 through the box cover 2.

[0036] The rectangular pipe 4 is arranged on the box cover 2. One end of the rectangular pipe 4 is arranged inside the box cover 2, and the other end of the rectangular pipe 4 is arranged outside the box cover 2. Plugging covers 40 are respectively hinged to the two open ends of the rectangular pipe 4 through torsion spring hinges.

[0037] It can be understood that by setting the torsion spring hinge, it is ensured that after the drugs are put into or taken out of the rectangular pipe 4, the plugging cover 40 can automatically close. This automatic closing function benefits from the torsion generated by the torsion spring inside the torsion spring hinge, ensuring the stability and reliability of the plugging cover 40, and at the same time avoiding the untimely manual closing. Among them, in order to further improve the user experience and facilitate the operation of taking and placing drugs, the torsion spring hinge can be arranged below the plugging cover 40, so that the plugging cover 40 can be easily opened in a downward flipping manner.

[0038] As a possible situation, in order to improve the sealing performance between the plugging cover 40 and the rectangular pipe 4, an elastic sealing gasket can be installed on the surface of the plugging cover 40 close to the rectangular pipe 4.

[0039] The humidity control mechanism 5 includes a housing 50, an external interface 51, a first three-way pipe 52, two first electromagnetic valves 53, a first gas path component 54 and a second gas path component 55.

[0040] Among them, the housing 50 is arranged on the side wall of the box body 1, the external interface 51 is connected and arranged on the housing 50, and one end of the external interface 51 is connected to the first three-way pipe 52.

[0041] It should be noted that in this embodiment, the end of the external interface 51 far from the housing 50 is connected to an external gas supply device, and the external gas supply device is used to supply dry gas into the external interface 51. Among them, the external gas supply device may include a compressor, a dryer, a filter, a pressure regulator, a flow meter, a valve, a gas storage cylinder, etc. Since it is prior art, the working principle will not be elaborated here. Among them, the gas storage cylinder can store inert gases such as nitrogen and helium or dry compressed air. For example, nitrogen is selected. Due to its own inertness, for drug substances that are prone to oxidation reactions in the air, using nitrogen as a protective gas can significantly enhance their stability, thereby effectively preventing the occurrence of the oxidation process. The specific selection can be determined according to the requirements of the actual application scenario, and the air pressure of the gas source needs to be above 2 bar, and the gas flow rate can be adjusted between 0 - 15 L / min according to the experimental requirements.

[0042] First electromagnetic valves 53 are respectively arranged on the two branches of the first three-way pipe 52. The air inlet of the first air path assembly 54 is connected to the first three-way pipe 52. The two air outlets of the first air path assembly 54 are respectively connected to the inside of the box body 1 and the inside of the rectangular pipe 4. The air inlet of the second air path assembly 55 is connected to the first three-way pipe 52. The two air outlets of the second air path assembly 55 are respectively connected to the inside of the box body 1 and the inside of the rectangular pipe 4.

[0043] Among them, the first air path assembly 54 and the second air path assembly 55 form a dry and wet two-way air path. The first air path assembly 54 is used to transport dry gas, while the second air path assembly 55 is used to transport humid gas.

[0044] Temperature and humidity sensors 6 are respectively arranged inside the box body 1 and the rectangular pipe 4. Among them, one temperature and humidity sensor 6 is used to obtain the temperature and humidity value in the box body 1, and the other temperature and humidity sensor 6 is used to obtain the temperature and humidity value in the rectangular pipe 4. And the two temperature and humidity sensors 6 can be connected to external devices through wireless or wired methods to realize real-time data transmission and display. In actual applications, users can view the temperature and humidity values inside the box body 1 and the rectangular pipe 4 at any time through external devices. This not only facilitates users' monitoring of the environment but also provides a basis for timely adjustment of environmental parameters.

[0045] It should be noted that the preset humidity range of the box body 1 is different from the preset humidity range in the rectangular pipe 4. In dry weather, the humidity value in the rectangular pipe 4 is adjusted to be greater than the humidity value in the box body 1. In relatively humid weather, the humidity value in the rectangular pipe 4 is adjusted to be less than the humidity value in the box body 1.

[0046] Specifically, taking dry weather as an example, the humidity value in the rectangular tube 4 is adjusted to be greater than the humidity value in the box body 1. When relevant personnel need to place drugs in the rectangular tube 4, the plugging cover 40 outside the box cover 2 will be opened. At this time, due to the entry of external dry air and the mixing with the air inside the rectangular tube 4, the humidity value inside the rectangular tube 4 will decrease. However, since the humidity value in the rectangular tube 4 itself is greater than the humidity value in the box body 1, and the humidity value in the rectangular tube 4 after mixing decreases, the humidity difference between the rectangular tube 4 and the box body 1 is reduced. Therefore, when transferring the drugs from the rectangular tube 4 to the box body 1 subsequently, when the air in the rectangular tube 4 mixes with the air in the box body 1, the change in the humidity value of the air is relatively small, which helps the humidity value in the box body 1 to quickly return to the preset humidity range value, greatly shortening the preparation time before the experiment.

[0047] If it is necessary to reduce the humidity value inside the box body 1 or the rectangular tube 4, it is achieved by opening the corresponding first solenoid valve 53 on the external air supply device and the first air path component 54. The external air supply device transports dry gas to the inside of the box body 1 or the rectangular tube 4 through the external interface 51, the first three-way pipe 52, and the first air path component 54, thereby reducing the humidity value inside the box body 1 or the rectangular tube 4.

[0048] If it is necessary to increase the humidity value inside the box body 1 or the rectangular tube 4, the corresponding first solenoid valve 53 on the external air supply device and the second air path component 55 is opened. The external air supply device transports gas to the inside of the box body 1 or the rectangular tube 4 through the external interface 51, the first three-way pipe 52, and the second air path component 55. Since the humidity of the gas will increase when passing through the second air path component 55, the humidity value inside the box body 1 or the rectangular tube 4 is increased.

[0049] In summary, it is possible to reduce the influence of the external environment on the humidity inside the box body 1 by controlling the humidity difference between the box body 1 and the rectangular tube 4, and the humidity value inside the box body 1 or the rectangular tube 4 can be adjusted through the humidity control mechanism 5. While ensuring the accuracy of the experimental results, the waiting time before the experiment is reduced, thereby improving the experimental efficiency and ensuring the research progress of the experiment.

[0050] To further clarify the previous embodiment, in an embodiment of the present application, as Figure 2 and Figure 4 shown, the first air path component 54 includes a second three-way pipe 540, a first pipe body 541, a second pipe body 542, and two second solenoid valves 543.

[0051] Among them, the air inlet end of the second three-way pipe 540 is communicated with the air outlet of the first three-way pipe 52. The two air outlet ends of the second three-way pipe 540 are respectively communicated with the first pipe body 541 and the second pipe body 542. One end of the first pipe body 541 far away from the second three-way pipe 540 penetrates through the inner wall of the housing 50 and the outer wall of the box body 1 and extends into the interior of the box body 1. One end of the second pipe body 542 far away from the second three-way pipe 540 penetrates through the inner wall of the housing 50 and the outer wall of the rectangular pipe 4 and extends into the interior of the rectangular pipe 4. Second electromagnetic valves 543 are respectively arranged on the outer walls of the second pipe body 542 and the first pipe body 541.

[0052] Specifically, turn on the external air supply device and the corresponding first electromagnetic valve 53 on the second three-way pipe 540. Next, adjust the states of the second electromagnetic valves 543 in the first air path assembly 54 according to specific requirements. If it is necessary to change the humidity in the box body 1, turn on the second electromagnetic valve 543 on the first pipe body 541. The external air supply device will transport the gas to the box body 1 through the external interface 51, the first three-way pipe 52, the second air path assembly 55, and the first pipe body 541. If it is necessary to change the humidity in the rectangular pipe 4, turn on the second electromagnetic valve 543 on the second pipe body 542. Then the gas will be transported to the interior of the rectangular pipe 4 through the external interface 51, the first three-way pipe 52, the second three-way pipe 540, and the second pipe body 542.

[0053] To further clarify the previous embodiment, in an embodiment of the present application, as Figure 2 and Figure 4 shown, the second air path assembly 55 includes a water tank 550, a third pipe body 551, a fourth pipe body 552, and two third electromagnetic valves 553.

[0054] Among them, the water tank 550 is arranged in the housing 50. One air outlet of the first three-way pipe 52 is communicated with the water tank 550. And the water tank 550 is arranged below the second three-way pipe 540. One end of the third pipe body 551 is communicated with the water tank 550. The other end of the third pipe body 551 penetrates through the inner wall of the housing 50 and is connected to the interior of the rectangular pipe 4. One end of the fourth pipe body 552 is connected to the interior of the box body 1. The other end of the fourth pipe body 552 is connected to the third pipe body 551. Third electromagnetic valves 553 are respectively arranged on the fourth pipe body 552 and the third pipe body 551. And the connection position of the fourth pipe body 552 and the third pipe body 551 is before the third electromagnetic valve 553 arranged on the third pipe body 551.

[0055] It should be noted that the water tank 550 is filled with water.

[0056] Specifically, turn on the external air supply device and the corresponding first electromagnetic valve 53 on the water tank 550. Next, adjust the states of the third electromagnetic valves 553 in the second air path assembly 55 according to specific requirements.

[0057] For example, if it is necessary to change the humidity in the box body 1, the third solenoid valve 553 on the fourth pipe body 552 is opened. When the gas transported by the external gas supply device supplies gas to the water source in the water tank 550 through the external interface 51 and the first three-way pipe 52, the combined action of factors such as the bubbles, turbulence, increased surface area, and reduced water surface temperature generated by the interaction between the air flow and the water source will accelerate the surface evaporation of the water, forming saturated water vapor in the water tank 550. The evaporated water vapor will enter the box body 1 along with the third pipe body 551 and the fourth pipe body 552, thereby increasing the humidity inside the box body 1.

[0058] Furthermore, as Figure 2 shown, the end of the first three-way pipe 52 connected to the water tank 550 is arranged near the bottom of the water tank 550. It can be understood that such a design facilitates the direct supply of gas into the water source in the water tank 550 to disturb the water in the water tank 550.

[0059] The end of the third pipe body 551 connected to the water tank 550 is arranged near the top of the water tank 550, and the liquid level in the water tank 550 is lower than the position where the third pipe body 551 is connected to the water tank 550. It can be understood that through the above settings, it will be convenient for the saturated water vapor to move upward into the third pipe body 551.

[0060] As a possible situation, in order to accelerate the flow rate of the saturated water vapor into the third pipe body 551, a guiding fan can also be installed in the third pipe body 551. Among them, the guiding fan can be composed of a micro motor and a fan blade.

[0061] In an embodiment of the present invention, as Figure 4 shown, the water tank 550 is provided with a water inlet valve 5500, and the water inlet valve 5500 penetrates through the inner wall of the box body 1.

[0062] It can be understood that by setting the water inlet valve 5500, it can be connected to an external water supply mechanism. Opening the water inlet valve 5500 and the water supply mechanism can inject a certain amount of water source into the water tank 550.

[0063] In an embodiment of the present invention, as Figure 1 shown, the sealing component 3 is a plug, and the plug is made of rubber material. It can be understood that by setting the plug, the through hole 20 can be elastically sealed, and when operating the drugs inside the box body 1, the plug can be pulled out, and the hand can directly reach into the box body 1 through the through hole 20, increasing the convenience of operation.

[0064] In another embodiment of the present invention, as Figure 5 shown, the sealing component 3 is a glove.

[0065] Among them, the plugging component 3 is a glove, and the glove extends from the outside into the interior of the box cover 2. During operation, there is no need to remove the plugging component 3. It is only necessary to put the hand into the glove to operate the medicine, which further improves the sealing performance of the operating box and further reduces the influence of external air on the internal air of the box body 1 during operation. Among them, thick latex gloves can be selected for the gloves.

[0066] In an embodiment of the present utility model, as Figure 1 shown, it further includes a buckle 8, and the box cover 2 is closely attached to the box body 1 through the buckle 8.

[0067] It should be noted that the buckle 8 described in this embodiment may include a lock seat and a lock hook. The lock seat is fixed on the box cover 2, the lock hook is pivotally connected to the box body 1, and the lock hook is reversibly hung on the lock seat. Since the structure of the buckle 8 is a prior art, it will not be elaborated here.

[0068] Among them, it can be understood that the box cover 2 can be closely attached and fixed to the box body 1 through the buckle 8, which further improves the sealing performance between the box cover 2 and the box body 1. And by flipping the lock hook upward, the lock hook can be disengaged from the lock seat, so that the box cover 2 can be opened, which is convenient for putting a moisture meter and a balance into the box body 1 before the experiment to measure the moisture content of the medicine and provide key data for evaluating the hygroscopicity of the medicine.

[0069] As a possible situation, in order to further improve the sealing performance between the box cover 2 and the box body 1, a sealing gasket can also be provided on the box body 1.

[0070] Furthermore, as Figure 1 shown, the above-mentioned operation box with controllable temperature and humidity further includes an industrial control computer 7. The industrial control computer 7 is arranged on the box body 1. Gas flow meters 56 are respectively arranged on two branches of the first three-way pipe 52. The industrial control computer 7 is electrically connected to the gas flow meters 56, the first solenoid valve 53, the second solenoid valve 543, the third solenoid valve 553 and the temperature and humidity sensor 6 respectively.

[0071] It should be noted that the industrial control computer 7 described in this embodiment has a display and input buttons, and the industrial control computer 7 is also electrically connected to an external air supply device.

[0072] Specifically, through the above settings, intelligent and precise adjustment of the temperature and humidity values inside the box body 1 and the rectangular pipe 4 can be achieved. For example, taking the adjustment of the humidity inside the box body 1 as an example, the humidity sensor 6 is used to obtain the humidity value inside the box body 1 and send the obtained humidity value to the industrial control computer 7. The industrial control computer 7 will immediately compare and analyze the current humidity value with the preset humidity range (which can be set according to the actual situation). If the current internal humidity value is greater than the preset humidity value range, the industrial control computer 7 controls the external air supply device, the first solenoid valve 53 corresponding to the first gas path component 54, and the second solenoid valve 543 on the first pipe body 541 to open, ensuring that dry gas can be accurately input into the box body 1, thereby reducing the humidity value inside the box body 1 until the humidity value drops back to the preset humidity range. Then, the industrial control computer 7 closes the external interface 51, the first solenoid valve 53, and the second solenoid valve 543, which can accurately control the humidity, facilitate the operation of the medicine under a controllable humidity, and effectively solve the influence of hygroscopicity on the sample quantity value. During this process, the gas flowmeter 56 can real-time monitor the gas flow passing through it and feedback this information to the industrial control computer 7. This helps to ensure that the gas flow input into the box body 1 is controllable, thereby precisely adjusting the humidity inside the box body 1.

[0073] In an embodiment of the present utility model, as Figure 1 shown, a handle is provided on the plugging cover 40. It can be understood that by providing the handle, it is convenient for relevant personnel to open the plugging cover 40, making the operation more convenient.

[0074] In summary, the operation box with controllable temperature and humidity according to the embodiment of the present utility model can reduce the waiting time before the experiment while ensuring the accuracy of the experimental results, thereby improving the experimental efficiency and ensuring the research progress of the experiment.
