The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0032] The following is in conjunction with the instruction manual appendix. Figure 1 To be continued Figure 4 This paper introduces the vacuum filtration flask and vacuum filtration device of this utility model.
[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, this application proposes a vacuum filtration flask, including a bottom bottle 10, a storage cup 20, and a vacuum filtration assembly. The vacuum filtration assembly includes a sealing sleeve 30, a funnel 40 fixedly connected to it, and a vacuum filtration port 50. A filter element is disposed in the funnel 40, and the funnel 40 is detachably and fixedly connected to the storage cup 20. The lower end of the vacuum filtration port 50 has a connection port 51, which is detachably and fixedly connected to the bottom bottle 10. The sealing sleeve 30 is used to seal the gap between the connection port 51 and the bottom bottle 10. The connection port 51 has a variable diameter structure to adapt to bottom bottles 10 of different diameters.
[0034] Therefore, the application solves the problem of small application range of the filter interface 50 in the prior art by providing a reducing structure at the connecting port 51, so that the filter bottle can be adapted to the bottom bottle 10 with different diameters. Specifically, the bottom bottle 10, the liquid storage cup 20 and the filter assembly constitute the basic structure of the filter bottle. The funnel 40 and the filter interface 50 in the filter assembly are fixedly connected through the sealing sleeve 30, which ensures the sealing of the system. The filter element in the funnel 40 is used for filtering liquid, and the detachable fixed connection design of the funnel 40 and the liquid storage cup 20 facilitates cleaning and replacement. The lower end connecting port 51 of the filter interface 50 is designed through a reducing structure, which can be adapted to the bottom bottle 10 with different diameters, thereby solving the problem of small application range of the filter interface 50 in the prior art. The sealing sleeve 30 ensures the sealing between the connecting port 51 and the bottom bottle 10, preventing liquid leakage. Through the mutual cooperation of these technical features, the application achieves the wide applicability of the filter bottle under different experimental conditions.
[0035] Further, in one embodiment, as shown in Figure 2 , the reducing structure is a reverse cone, and the sealing sleeve 30 is a conical structure matched with the reverse cone.
[0036] Specifically, the reverse cone reducing structure enables the filter interface 50 to adapt to the bottom bottle 10 with different diameters, thereby expanding the application range of the filter bottle. As a preferred embodiment, the reverse cone reducing structure can be realized by providing a gradually tapered conical portion at the connecting port 51, which enables the bottom bottle 10 with different diameters to be tightly matched. Further, the sealing sleeve 30 adopts a conical structure matched with the reverse cone, which ensures the sealing between the connecting port 51 and the bottom bottle 10, preventing liquid leakage. For example, the sealing sleeve 30 can be made of elastic material, such as rubber or silicone, to ensure good sealing effect on the bottom bottle 10 with different diameters.
[0037] Further, in another embodiment, as shown in Figure 3 and Figure 4 , the reducing structure is a stepped structure composed of multiple pipe segments with different diameters, and the multiple pipe segments with different diameters gradually decrease towards the bottom bottle 10, and the sealing sleeve 30 has multiple sealing sleeves 30, and the diameters of the multiple sealing sleeves 30 are matched with the multiple pipe segments with different diameters one by one.
[0038] For example, as shown in Figure 4As shown, the variable-diameter structure can be composed of three pipe segments with different diameters, namely the first pipe segment 52, the second pipe segment 53, and the third pipe segment 54, which have diameters decreasing in order. The number of sealing sleeves 30 can match the number of pipe segments, for example, three sealing sleeves 30, each of which has a diameter matching the diameter of the corresponding pipe segment. In addition, the sealing sleeves 30 can be made of elastic material to ensure sealing performance when connecting the bottom bottles 10 with different diameters. In other embodiments, four or five pipe segments with different diameters can also be provided, and the number and diameters of the sealing sleeves 30 are correspondingly matched.
[0039] Thus, the variable-diameter structure forms a stepped structure by providing multiple pipe segments with different diameters, so that the filtration interface 50 can adapt to bottom bottles 10 with different diameters, thereby expanding the application range of the filtration bottle. The diameters of the multiple sealing sleeves 30 are matched with the multiple pipe segments with different diameters, ensuring sealing performance when connecting the bottom bottles 10 with different diameters, and solving the technical problem of small application range of the filtration interface 50 in the prior art.
[0040] Further, in one embodiment, the sealing sleeve 30 is made of elastic material.
[0041] Specifically, the elastic material can include, but is not limited to, rubber, silicone, polyurethane, and other materials with good elasticity and wear resistance. These materials can deform under external force and return to their original shape after the external force is removed, thereby ensuring that the sealing sleeve 30 can effectively seal the gap between the connection port 51 and the bottom bottle 10. As a preferred embodiment, the sealing sleeve 30 can be designed to match the shape of the variable-diameter structure of the connection port 51, for example, if the connection port 51 is inverted conical, the sealing sleeve 30 can also be designed to have a corresponding conical structure to better adapt to bottom bottles 10 with different diameters.
[0042] Further, in one embodiment, the filtration interface 50 is provided with an air outlet 55.
[0043] Specifically, the air outlet 55 can be provided on the side wall of the filtration interface 50 to facilitate the connection of the air pipe. As a preferred embodiment, the air outlet 55 can be designed to have a stepped or tapered radius structure to facilitate the replacement of air pipes with different diameters. Further, the air outlet 55 can also be equipped with a sealing ring to ensure the sealing performance of the connection to prevent gas leakage.
[0044] By providing the air outlet 55 on the filtration interface 50, the air pipe can be directly connected to realize the air extraction function, simplifying the structure of the filtration bottle and improving the filtration efficiency. Specifically, the provision of the air outlet 55 enables the filtration bottle to more effectively exchange gases during the filtration process, reducing the filtration time and improving the experimental efficiency.
[0045] In another embodiment, the suction port 55 can also be provided at a position of the bottom bottle 10 close to the suction interface 50.
[0046] Further, in one of the embodiments, the suction bottle further comprises a fixing clamp 60 for fixing the connection between the liquid storage cup 20 and the funnel 40.
[0047] Specifically, the fixing clamp 60 can achieve its function in various ways. For example, the fixing clamp 60 can be designed as a springy clamp capable of tightly clamping the connection part of the liquid storage cup 20 and the funnel 40, ensuring the stable connection therebetween. As a preferred embodiment, the fixing clamp 60 can be made of metal or high-strength plastic to ensure its durability and stability. Further, the design of the fixing clamp 60 can consider adding anti-slip textures or rubber pads to improve the fixing effect and prevent loosening due to vibration or improper operation during use.
[0048] Through the design of the fixing clamp 60, the liquid storage cup 20 and the funnel 40 are not easy to loosen due to vibration or improper operation, thereby improving the stability and use safety of the suction bottle.
[0049] The present application also provides a suction device comprising a vacuum pump, a suction pipe and the suction bottle according to any one of the above technical solutions, one end of the suction pipe being connected to the vacuum pump and the other end being connected to the suction bottle.
[0050] Among them, the vacuum pump is used to generate negative pressure, the suction pipe is used to connect the vacuum pump and the suction bottle, and the suction bottle is used to perform liquid filtration operation under reduced pressure. Specifically, by using the suction bottle according to any one of the above technical solutions, the suction interface can be adapted to bottom bottles of different diameters, thereby expanding the application range of the suction bottle.
[0051] Further, the suction pipe can be a rubber hose. As a preferred embodiment, the rubber hose has good elasticity and sealing property, which can effectively prevent gas leakage and ensure the stability and safety of the suction process.
[0052] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
