Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a splash-proof modifier sample stirring device. Background Art

[0002] In chemical experiments, materials research and development, and industrial production, stirring devices are widely used to mix samples such as reagents, modifiers, and coatings. However, traditional stirring equipment often faces problems such as sample splashing, liquid leakage, and the release of volatile gases during operation. This not only leads to sample waste, but also may pollute the operating environment and even endanger the safety of laboratory personnel. Therefore, improving the splash protection function of stirring equipment has become a key direction of technological development in the industry.

[0003] Existing splash-proofing designs primarily rely on fixed protective shields or sealed containers. While these can mitigate splash and leakage issues to some extent, they also introduce a host of new challenges. For example, fixed protective shields lack sufficient sealing, making it difficult to completely prevent liquid splashing while maintaining efficient sample mixing. The complex structure of sealed containers not only increases the difficulty of operation and cleaning, but also limits flexible sample handling, making it difficult to accommodate mid-process additions or observations.

[0004] In view of this, the inventors specially designed a splash-proof modifier sample stirring device, which resulted in the present invention. Utility Model Content

[0005] The purpose of this application is to provide a splash-proof modifier sample stirring device, which at least solves the technical problem of liquid splashing and leakage during the stirring process of the existing stirring device, and ensures operational flexibility and convenience in cleaning and maintenance of the equipment.

[0015] In a further embodiment, the stopper is a transparent plate of polycarbonate.

[0016] In a further embodiment, a positioning groove is provided on the base for facilitating the positioning and placement of the sample.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0033] like Figure 1 As shown, the present invention provides a splash-proof modifier sample stirring device, comprising a base 1, a connecting shaft 2 being fixed to the base 1, a stirring body 3 being fixedly mounted on the upper end of the connecting shaft 2, and a stirring shaft 4 being provided at one end of the stirring body 3; a protective cover assembly 5 for preventing the sample from splashing is detachably provided on the stirring body 3, and the protective cover assembly 5 is sleeved and covers the stirring shaft 4; wherein the protective cover assembly 5 includes a fixed portion 51 detachably provided on the stirring body 3, an adjustable portion 52 of different lengths being provided at one end of the fixed portion 51, and a stopper 53 for preventing the stirring shaft 4 from splashing the sample when in operation being fixedly provided at one end of the adjustable portion 52. By sleeved with the protective cover assembly 5, the problem of splashing during sample stirring is effectively controlled.

[0034] like Figure 2 and Figure 4 As shown, the adjustment portion 52 is an aluminum foil tube. This provides a lightweight, flexible, and adjustable connection method. The aluminum foil tube can be adjusted to the height of the sample container or the stirring requirements, adapting to different sample stirring environments. The aluminum foil tube is lightweight and mechanically strong, so it does not increase the weight of the device while maintaining good stability.

[0035] like Figure 4 As shown, a magnetic member 12 is fixed to the top of the fixing portion 51, facilitating quick assembly and disassembly of the protective cover assembly 5 and ensuring a secure connection. This improves the ease of operation of the device, allowing users to quickly install or remove the protective cover assembly 5. The magnetic connection eliminates the need for cumbersome mechanical locking while maintaining the stability of the protective cover.

[0036] Several vent holes 6 are provided in the fixed portion 51 to balance pressure fluctuations within the protective cover during stirring, preventing pressure buildup. This maintains pressure equilibrium inside and outside the protective cover, preventing deformation or instability caused by internal gas pressure. This improves the safety of the device, especially when handling volatile reagents.

[0037] A removable filter 7 is added inside the vent 6 to filter liquid particles or other substances that may escape during the stirring process. This further reduces the risk of sample liquid spraying or scattering during stirring, protecting the cleanliness of the external environment. The removable design of the filter 7 facilitates cleaning and replacement, improving the maintenance convenience of the device.

[0038] like Figure 3 and Figure 4 As shown, the stopper 53 defines an injection port 8, to which is hingedly connected a flap 9 that matches the shape of the injection port 8. The design of the injection port 8 and the hinged flap 9 on the stopper 53 facilitates the addition of reagents during the stirring process without removing the protective cover. This improves the flexibility of the stirring process, allowing the user to add samples or reagents in real time as needed. The flap 9 ensures a good seal when the injection port 8 is closed, further preventing liquid splashing.

[0039] like Figure 3 As shown, the bottom of the stopper 53 is secured with a liquid collection trough 10 for collecting splashed liquid. This prevents splashed liquid from contaminating the equipment and operating table, improving the cleanliness of the mixing process. The detachable design of the liquid collection trough 10 facilitates timely cleaning, maintaining the hygiene of the equipment.

[0040] By using transparent polycarbonate to form the stopper 53, both protection and visualization are achieved. Users can observe the sample's state during stirring in real time without removing the protective cover. Polycarbonate offers high strength, excellent transparency, and a certain degree of chemical resistance, making it suitable for a variety of reagent stirring environments.

[0041] like Figure 1 and Figure 3 As shown, a positioning groove 11 is provided on the base 1 to facilitate the positioning and fixing of the sample container. This ensures that the sample container does not move during the stirring process, improving stirring stability. The positioning groove 11 is designed to be compatible with a variety of sample container sizes, expanding the applicability of the device.

[0042] In summary, the above structure achieves good liquid collection and visualization by centrally addressing the problem of splashing during the stirring process, particularly through the combined design of the transparent stopper 53 and the liquid collection tank 10. The combination of the exhaust hole 6 and the filter screen 7 effectively alleviates the problem of gas pressure accumulation. The flexible design of the magnetic element 12 and the aluminum foil tube adjustment portion 52 improves the operational convenience and adaptability of the device. The present invention has a reasonable structure and is easy to operate, suitable for a variety of sample stirring scenarios, and can significantly improve the safety and operational efficiency of the sample stirring process.

[0043] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
