Description

Technical Field

[0001] This utility model belongs to the field of battery powder moisture protection technology, specifically relating to a perovskite battery powder moisture protection device. Background Technology

[0002] Perovskite solar cells, as a novel photovoltaic device, have become a research hotspot in the field of new energy due to their advantages such as high photoelectric conversion efficiency and low-cost fabrication. Among them, perovskite powder is the core raw material for manufacturing perovskite solar cells. This type of powder material is extremely sensitive to water and oxygen. Trace amounts of water and oxygen can cause damage to the crystal structure of the powder and deterioration of its performance, which in turn seriously affects the fabrication quality and photoelectric performance of perovskite solar cells. Therefore, effective moisture-proof storage of perovskite powder is crucial.

[0003] Currently, the industry commonly uses vacuum drying ovens to store perovskite battery powders. Vacuuming removes water and oxygen from the oven to meet the powder's moisture-proof storage requirements. Existing vacuum drying ovens have vacuum tube connection ports for connecting vacuum pumps. To protect these ports, a rotatable cover is typically installed. Normally, the cover is closed over the vacuum tube connection port to prevent external impurities or water and oxygen penetration. When vacuuming is required, the operator manually rotates the cover to expose the vacuum tube connection port for connection.

[0004] However, the existing cover structure of vacuum drying ovens has obvious defects: the cover is only connected to the box body through a simple hinge structure and lacks an effective positioning mechanism. After being rotated open, the cover is prone to fall naturally under its own weight, causing the vacuum tube connection port to be blocked again. This not only affects the smooth progress of the vacuuming operation, but may also cause collision damage between the vacuum tube and the connection port. At the same time, the cover also lacks an additional fixed protective structure, which is prone to loosening during transportation or accidental contact, further reducing the protective performance.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 This utility model provides a moisture-proof device for perovskite battery powder, including...

[0027] Box 1 has a vacuum tube connection port 14 on its side surface. Box 1 provides a closed storage space for perovskite battery powder. The vacuum tube connection port 14 can be precisely connected to a vacuum pump to ensure that subsequent vacuuming operations can be carried out smoothly, creating a low-water-oxygen moisture-proof environment inside the box and ensuring the quality of powder storage.

[0028] The protective limiting component includes a fixed frame 3 installed on the side surface of the housing 1 and located outside the vacuum tube connection port 14. This frame provides initial protection to the vacuum tube connection port 14 from the outside, preventing external impurities from directly impacting or contaminating the connection port. It also provides a stable mounting base for the cover 4, improving the overall stability of the protective structure. The cover 4 is hinged to the fixed frame 3 and engages with it, allowing for flexible rotation to open and close the vacuum tube connection port 14. The engaging connection structure ensures that the cover 4 fits tightly against the fixed frame 3 when closed, enhancing the protection of the vacuum tube connection port. The protective effect of the opening 14 reduces the infiltration of external water and oxygen. The first magnetic post 41 embedded in the cover 4, the fastening block 2 installed on the side surface of the box 1, and the second magnetic post 21 set on the fastening block 2 and connected to the first magnetic post 41, the first magnetic post 41 and the second magnetic post 21 cooperate to limit and fix the cover 4 through magnetic attraction after the cover 4 is opened, effectively preventing the cover 4 from falling naturally due to its own weight and blocking the vacuum tube connection port 14, ensuring smooth vacuuming operation; the setting of the fastening block 2 provides a stable mounting carrier for the second magnetic post 21 to ensure the reliability of the magnetic attraction structure.

[0029] In this embodiment, a fixing block 42 is also provided on the cover 4, and a fixing groove 31 is opened on the side surface of the fixing frame 3 for the fixing block 42 to be inserted. The cooperation between the fixing block 42 and the fixing groove 31 can further enhance the connection stability between the cover 4 and the fixing frame 3 when the cover 4 is closed, prevent the cover 4 from loosening during transportation or accidental contact, and at the same time assist in positioning the cover 4 at the closing position to ensure that the cover 4 is accurately locked, thereby improving the overall robustness of the protective structure. A clamping component is provided inside the fixing groove 31 to clamp and fix the fixing block 42 inserted into the fixing groove 31, further enhancing the tightness of the connection between the cover 4 and the fixing frame 3, while improving the anti-loosening ability of the cover 4 after it is closed, and ensuring the durability of the protective effect.

[0030] In this embodiment, the clamping assembly includes a telescopic spring 8 disposed on the inner side of the fixing groove 31, and a clamping piece 7 disposed at one end of the telescopic spring 8 and capable of clamping the fixing block 42. The telescopic spring 8 has elastic telescopic characteristics, which can drive the clamping piece 7 to adaptively adjust the clamping force according to the insertion of the fixing block 42, ensuring stable clamping of the fixing block 42. The clamping piece 7 directly contacts the fixing block 42, increasing the contact area, improving clamping stability, and further strengthening the connection and fixing effect between the cover 4 and the fixing frame 3.

[0031] In this embodiment, an inner liner 5 is also included inside the housing 1. This inner liner provides a more precise storage environment for the perovskite battery powder, reduces the impact of external environmental changes on the powder inside the housing 1, and allows for independent control of the internal environment, improving the accuracy of moisture-proof and temperature control performance, thus better protecting the powder quality. The inner liner 5 also includes a support frame 51 mounted on the inner side of the inner liner 5 and a partition 6 mounted on the support frame 51. The support frame 51 provides stable support for the partition 6, ensuring that the partition 6 can stably support the powder container. The partition 6 can divide the internal space of the inner liner 5 into multiple layers, enabling the classified storage of different batches or types of perovskite battery powder, preventing powder mixing, facilitating layered management and retrieval, and improving operational convenience.

[0032] In this embodiment, a door 11 is also included, which is hinged to the front surface of the box body 1. The door 11 is located on the outside of the inner liner 5 and can be opened and closed flexibly, making it convenient for operators to open the box body 1 to take out or maintain the inner liner 5 and the powder. The door 11 is located on the outside of the inner liner 5 and can form a double sealing structure with the box body 1, further blocking external water and oxygen from entering the inner liner 5, enhancing the overall moisture-proof effect, and protecting the inner liner 5 from external collision damage.

[0033] In this embodiment, a digital display pressure regulator 12 and a microcomputer LCD instrument 13 are also installed on the front surface of the housing 1. The microcomputer LCD instrument 13 is located below the digital display pressure regulator 12. The digital display pressure regulator 12 allows operators to intuitively view and accurately adjust the pressure inside the housing 1, ensuring that the vacuuming operation can achieve the required vacuum level and meet the requirements for moisture-proof powder storage. The microcomputer LCD instrument 13 can display key parameters such as temperature, humidity, and vacuum level inside the housing 1 in real time, facilitating operators to monitor the storage environment in real time, promptly detect and handle abnormal situations, and ensure the safety of powder storage. The vertical arrangement of the two instruments makes the operating interface more organized and convenient for operators to view and operate.

[0034] The working principle and usage process of this invention: Hold the handle of the door 11, open the door 11 to expose the inner liner 5 inside the box 1, and place the container containing perovskite battery powder stably on the partition 6; according to the batch, type or usage requirements of the powder, use the multi-layer partition 6 to classify and place the powder to avoid mixing different powders; during the placement process, ensure that the container does not exceed the edge of the partition 6 and maintains a certain distance from the inner wall of the inner liner 5 to prevent the container from tipping over or affecting the airflow inside the inner liner 5, and to ensure the safety of powder storage; after confirming that the powder container has been placed, push the door 11 to make it fit tightly against the front surface of the box 1;

[0035] Rotate the cover 4 so that the first magnet post 41 on the cover 4 gradually approaches the second magnet post 21 on the fastening block 2 until the two attract each other. The cover 4 remains open and exposes the vacuum tube connection port 14. Connect the end of the vacuum tube of the vacuum pump to the vacuum tube connection port 14 to complete the connection of the vacuum pumping pipeline.

[0036] Turn on the vacuum pump and simultaneously observe the digital display voltage regulator 12 on the front surface of chamber 1. Based on the moisture-proof requirements of the perovskite battery powder, precisely control the pumping rate of the vacuum pump through the adjustment button of the digital display voltage regulator 12 to gradually increase the vacuum level inside the inner liner 5. During this process, monitor the microcomputer LCD instrument 13 in real time, which will display key parameters such as temperature, humidity, and vacuum level inside chamber 1. Once the vacuum level reaches the set requirement, keep the vacuum pump running for 5-10 minutes to ensure that water and oxygen inside the chamber are fully discharged, and then turn off the vacuum pump.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
