[0007] Preferably, the exhaust assembly includes a support plate, which is fixedly connected to the inner wall of the protective cover, and the surface of the support plate is provided with exhaust holes. The inner wall of the support plate is penetrated by a connecting rod and is slidably connected thereto, and the front surface of the connecting rod is fixedly connected to a sealing plate, and the rear surface of the sealing plate is elastically connected to the support plate via a sealing spring.

[0008] Preferably, a positioning frame is provided on the front surface of the protective cover, and the front surface of the protective cover is rotatably connected to a limiting plate, and the limiting plate is plugged into the inner wall of the positioning frame.

[0009] Preferably, the locking assembly includes a slider, the slider is slidably connected to the inner wall of the cabinet, the storage box is provided with a slide groove at one end close to the slider, and the front surface of the slide groove is provided with a locking groove.

[0010] Preferably, the slider is slidably connected to the inner wall of one end of the cabinet with a ball block, the ball block and the slider are elastically connected via a positioning spring, and a ball groove is provided on the front surface of the cabinet.

[0011] Preferably, the drying assembly includes a filter box, which is plugged into the rear surface of the guide frame. The filter box and the temperature control device are connected to each other through a connecting pipe, and a drying plate is plugged into the upper surface of the filter box.

[0012] Preferably, the inner wall of the guide frame is fixedly connected to a support frame near the top of the filter box, the upper end of the support frame is fixedly connected to a sliding frame, the upper surface of the sliding frame is penetrated by and slidably connected to a sliding rod, the outer wall of the sliding rod is fixedly connected to a sliding plate, and the sliding plate is provided with a protrusion at one end close to the drying plate, the protrusion is set to a trapezoidal shape and the overall height gradually increases from back to front, and the sliding frame and the sliding rod are elastically connected by a closed spring.

[0014] A method for using a moisture-proof storage device for pharmaceutical supplies comprises the following steps: S1: Temperature control cycle. The temperature control device transmits the regulated temperature gas to the filter box through the connecting pipe. After the drying plate absorbs moisture, the dry gas enters the guide frame. When the storage box is inserted into the cavity of the cabinet, the rear end of the storage box squeezes the extrusion plate of the self-sealing component, pushing the baffle to compress the sealing spring, so that the ventilation slot on the rear surface of the cabinet opens, and the dry gas enters the storage box through the ventilation slot, maintaining the temperature and humidity of the storage environment stable. At the same time, the self-sealing component on the inner wall of the storage box is subjected to the gas pressure inside the cabinet, the baffle compresses the sealing spring, and the ventilation slot at the rear end of the storage box opens synchronously to ensure gas circulation; S2: Box removal: When the storage box needs to be removed, the slider of the locking assembly is toggled to move it up along the slide slot of the storage box. The ball block compresses the positioning spring and disengages the ball slot of the cabinet. The slider slides from the locking slot of the storage box into the slide slot. At this time, the storage box can be pulled out as a whole by the handle of the storage box, making it easy to carry all the medicines in the box; S3: Self-sealing cabinet. When a storage box is removed from the cabinet, the self-sealing assembly in the corresponding chamber loses its external squeezing force, and the sealing spring rebounds, pushing the baffle forward. This drives the sealing plate to seal the ventilation slot, isolating the chamber from the guide frame, preventing temperature-controlled drying gas from entering the empty chamber and reducing energy waste. At the same time, the sealing spring of the self-sealing assembly inside the removed storage box pushes the baffle and sealing plate to close its own ventilation slot, forming a closed space, reducing the impact of the external environment on the medicines in the box and maintaining a stable internal temperature. S4: Equipment maintenance: When the operator needs to replace the drying plate, he can first pull out the filter box of the drying component. The closing spring of the drying component pushes the sliding plate down and closes the support frame through the protrusion to prevent external impurities from entering the guide frame and the cabinet. When the replacement step is completed, the filter box can be reinstalled. The front end will squeeze the protrusion, driving the sliding plate to move up along the slide rod and the sliding frame to open the support frame, ensuring that the gas circulation returns to normal.

[0015] The present invention provides a moisture-proof storage device for pharmaceutical products and a method for using the same. The device has the following beneficial effects: 1. The present invention provides a self-sealing component. When the storage box inside a chamber is taken out, the sealing spring at the rear of the corresponding chamber will push the corresponding baffle to move forward, and the baffle will drive the sealing plate to move forward synchronously. In this way, the ventilation groove can be sealed with the help of the sealing plate. By sealing the ventilation groove, the chamber can be separated from the guide frame, so that the gas output by the temperature control device cannot reach the chamber, thereby reducing energy consumption and improving energy utilization.

[0016] 2. The present invention is provided with a locking assembly. When it is necessary to go out for medical tasks, the slider can be moved upward, so that the slider can be moved from the locking groove to the inside of the slide groove. Then the handle can be pulled to take the entire storage box out from the inside of the chamber. In this way, all the medicines inside can be taken out directly without taking out a specific medicine separately, which is more convenient when taking medicine.

[0017] 3. The present invention additionally arranges a set of self-sealing components on the rear surface of the storage box. When the operator takes out the storage box, the sealing spring arranged on the inner wall of the storage box will push the baffle to drive the sealing plate to close the ventilation groove at the rear end of the storage box. In this way, a closed space can be formed inside the storage box, which can reduce the impact of the external environment on the storage box and maintain the temperature. The overall storage effect of the device is better.

[0018] 4. The present invention provides a sliding plate. When the drying plate needs to be replaced, the filter box can be pulled out of the guide frame. At this time, the closing spring will push the sliding plate downward to close the support frame. In this way, the internal space of the cabinet and the guide frame can be kept closed, which can prevent external impurities from entering the interior of the cabinet and the guide frame during the replacement of the drying plate.

The inner wall of the storage box 4 is fixedly connected to a stopper 46, which can limit the protective cover 41 to prevent the protective cover 41 from excessive rotation.

[0028] A method for using a moisture-proof storage device for pharmaceutical supplies comprises the following steps: S1: Temperature control cycle, the temperature control device 2 transports the regulated temperature gas to the filter box 81 through the connecting pipe 6. After the drying plate 82 absorbs moisture, the dry gas enters the guide frame 3. When the storage box 4 is inserted into the chamber of the cabinet 1, the rear end of the storage box 4 squeezes the extrusion plate 76 of the self-sealing component 7, pushing the baffle 73 to compress the sealing spring 75, so that the ventilation groove 71 on the rear surface of the cabinet 1 opens, and the dry gas enters the interior of the storage box 4 through the ventilation groove 71, maintaining the temperature and humidity of the storage environment stable. At the same time, the self-sealing component 7 on the inner wall of the storage box 4 is subjected to the gas pressure inside the cabinet, and the baffle 73 compresses the sealing spring 75, and the ventilation groove 71 at the rear end of the storage box 4 opens synchronously to ensure gas circulation.

[0029] S2: Box removal: When the storage box 4 needs to be taken out, the slider 51 of the locking assembly 5 is moved upward along the slide groove 43 of the storage box 4. The ball block 53 compresses the positioning spring 52 to disengage from the ball groove 54 of the cabinet 1, and the slider 51 slides from the locking groove 44 of the storage box 4 into the slide groove 43. At this time, the storage box 4 can be pulled out as a whole through the handle 45 of the storage box 4, which is convenient for carrying all the medicines in the box.

[0030] S3: Cabinet self-sealing. When a storage box 4 is removed from cabinet 1, the self-sealing assembly 7 of the corresponding chamber in cabinet 1 loses its external compressive force. Sealing spring 75 rebounds, pushing baffle 73 forward, driving sealing plate 72 to seal vent slot 71, isolating the chamber from guide frame 3. This prevents temperature-controlled drying gas from entering the empty chamber and reduces energy waste. Simultaneously, sealing spring 75 of the self-sealing assembly 7 within the removed storage box 4 pushes baffle 73 and sealing plate 72 to close its own vent slot 71, forming a closed space. This reduces the impact of the external environment on the medicines within the box and maintains a stable internal temperature.

[0031] S4: Equipment maintenance: When the operator needs to replace the drying plate 82, he can first pull out the filter box 81 of the drying component 8. The closing spring 88 of the drying component 8 pushes the sliding plate 84 downward, and closes the support frame 83 through the protrusion 85 to prevent external impurities from entering the guide frame 3 and the cabinet 1. When the replacement step is completed, the filter box 81 can be reinstalled. Its front end will squeeze the protrusion 85, driving the sliding plate 84 to move up along the slide rod 86 and the sliding frame 87 to open the support frame 83, ensuring that the gas circulation returns to normal.

When the storage box (4) is inserted into the chamber of the cabinet (1), the rear end of the storage box (4) squeezes the extrusion plate (76) of the self-sealing component (7), pushing the baffle (73) to compress the sealing spring (75), so that the ventilation groove (71) on the rear surface of the cabinet (1) opens, and the dry gas enters the interior of the storage box (4) through the ventilation groove (71), maintaining the temperature and humidity of the storage environment stable. At the same time, the self-sealing component (7) on the inner wall of the storage box (4) is subjected to the gas pressure inside the cabinet, and the baffle (73) compresses the sealing spring (75), and the ventilation groove (71) at the rear end of the storage box (4) opens synchronously to ensure gas circulation; S2: Box removal: When the storage box (4) needs to be removed, the slider (51) of the locking assembly (5) is moved upward along the slide groove (43) of the storage box (4), the ball block (53) compresses the positioning spring (52) to disengage from the ball groove (54) of the cabinet (1), and the slider (51) slides from the locking groove (44) of the storage box (4) into the slide groove (43). At this time, the storage box (4) can be pulled out as a whole through the handle (45) of the storage box (4), making it easy to carry all the medicines in the box; S3: The box is self-sealed. When a storage box (4) is taken out from the cabinet (1), the self-sealing component (7) of the corresponding chamber of the cabinet (1) loses the external squeezing force, and the sealing spring (75) rebounds to push the baffle (73) forward, driving the sealing plate (72) to close the ventilation groove (71), isolating the chamber from the guide frame (3), preventing the temperature-controlled drying gas from entering the empty chamber, and reducing energy waste. At the same time, the sealing spring (75) of the self-sealing component (7) inside the taken-out storage box (4) pushes the baffle (73) and the sealing plate (72) to close its own ventilation groove (71), forming a closed space, reducing the impact of the external environment on the medicines in the box, and maintaining a stable internal temperature; S4: Equipment maintenance: When the operator needs to replace the drying plate (82), he can first pull out the filter box (81) of the drying assembly (8). The closing spring (88) of the drying assembly (8) pushes the sliding plate (84) downward, and closes the support frame (83) through the protrusion (85) to prevent foreign matter from entering the guide frame (3) and the cabinet (1). When the replacement step is completed, the filter box (81) can be reinstalled. The front end of the filter box will squeeze the protrusion (85), driving the sliding plate (84) to move upward along the slide rod (86) and the sliding frame (87) to open the support frame (83), ensuring that the gas circulation returns to normal.
