[0004] To achieve the above objectives, this utility model provides the following technical solution: a qualitative filter paper storage device that is easy to handle, comprising a cup body, a cover at the upper end of the cup body, a lifting seat slidably connected inside the cup body, a lifting spring between the lower surface of the lifting seat and the cup body, a retrieval cover protruding upward on the upper surface of the cover, a retrieval slit at the lower semicircle of the retrieval cover, a retrieval groove at the middle position of the upper surface of the retrieval cover near the retrieval slit, the retrieval groove communicating with the retrieval slit, a limiting edge on the upper surface of the cover and outside the retrieval cover, and a protective cover at the position corresponding to the retrieval slit on the upper surface of the retrieval cover.

[0005] Preferably, the protective cover has a semi-circular structure, and the two ends of the protective cover are provided with pivot seats. The protective cover is rotatably connected to the retrieval cover through the pivot seats via a pivot. The upper edge of the outer surface of the protective cover is provided with an opening edge, and the lower edge of the protective cover abuts against the limiting edge.

[0006] Preferably, threaded sections are provided at the upper edge of the outer surface of the cup body and at corresponding positions on the inner surface of the lid body, and the lid body is threadedly connected to the cup body through the threaded sections.

[0007] Preferably, a limiting seat is provided at the middle position of the lower surface of the lifting seat and on the outside of the lifting spring, and the upper end of the lifting spring is spliced ​​and connected to the limiting seat.

[0008] Preferably, a fixing seat is provided on the inner surface of the lower wall of the cup body and inside the lifting spring, and the lower end of the lifting spring is spliced ​​and connected to the fixing seat.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the qualitative filter paper that needs to be temporarily stored is stored inside the storage device. When the qualitative filter paper needs to be taken out, the protective cover is opened and the staff can take out the qualitative filter paper inside through the retrieval slot with their fingers. It is no longer necessary to disassemble the factory packaging of the qualitative filter paper every time, making the retrieval operation process simpler and avoiding the possibility of filter paper contamination.

[0016] 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.

[0017] Please see Figure 1-5This utility model provides a qualitative filter paper storage device that is easy to handle, including a cup body 1, a cover body 2 at the upper end of the cup body 1, a lifting seat 3 slidably connected inside the cup body 1, a lifting spring 4 between the lower surface of the lifting seat 3 and the cup body 1, a retrieval cover 5 protruding upward on the upper surface of the cover body 2, a retrieval slit 6 at the semi-circular part of the lower end of the retrieval cover 5, a retrieval groove 7 at the middle position of the upper surface of the retrieval cover 5 near the retrieval slit 6, the retrieval groove 7 communicating with the retrieval slit 6, a limiting edge 8 on the upper surface of the cover body 2 and outside the retrieval cover 5, and a protective cover 9 at the position corresponding to the retrieval slit 6 on the upper surface of the retrieval cover 5.

[0018] In use, after unpacking the complete qualitative filter paper, place it inside the cup body 1. Press the filter paper to overcome the elasticity of the lifting spring 4, causing the lifting seat 3 to move downward. Then, place the cover 2 on the upper end of the cup body 1. The cover 2 limits the filter paper inside the cup body 1. When the filter paper needs to be removed, open the protective cover 9. The operator places their fingers inside the retrieval slot 7 against the filter paper. Since the friction between the fingers and the filter paper is greater than the friction between the filter papers, the filter paper can be removed from inside the retrieval cover 5 through the retrieval slot 6. The lifting seat 3 moves upward under the elasticity of the lifting spring 4, applying a lifting force to the filter paper to ensure that the top layer of filter paper is inside the retrieval cover 5. After removing the filter paper, close the protective cover 9. The protective cover 9 rests against the limiting edge 8, protecting the filter paper inside the cup body 1.

[0019] The protective cover 9 has a semi-circular structure. The protective cover 9 has a pivot seat 10 at both ends. The protective cover 9 is rotatably connected to the retrieval cover 5 through the pivot seat 10 via a pivot. The upper edge of the outer surface of the protective cover 9 is provided with an opening edge 11. The lower edge of the protective cover 9 abuts against the limiting edge 8. The protective cover 9 is rotatably connected to both sides of the retrieval cover 5 through the pivot seat 10 via a pivot. When it is necessary to open and close the protective cover 9, the staff can open and close it through the opening edge 11.

[0020] Threaded sections 12 are provided at the upper edge of the outer surface of the cup body 1 and at the corresponding positions on the inner surface of the lid body 2. The lid body 2 is threadedly connected to the cup body 1 through the threaded sections 12, and the lid body 2 is threadedly connected to the upper end of the cup body 1 through the bolt sections 12, which ensures the connection strength while making it easy to remove the lid body 2 from the cup body 1.

[0021] A limiting seat 13 is provided at the middle position of the lower surface of the lifting seat 3 and on the outside of the lifting spring 4. The upper end of the lifting spring 4 is spliced ​​with the limiting seat 13, and the upper end of the lifting spring 4 is connected to the lifting seat 3 through the limiting seat 13.

[0022] A fixing seat 14 is provided on the inner surface of the lower wall of the cup body 1 and inside the lifting spring 4. The lower end of the lifting spring 4 is spliced ​​with the fixing seat 14, and the lower end of the lifting spring 4 is connected to the cup body 1 through the fixing seat 14.

[0023] Although embodiments of the present invention have been shown and described, 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.
