[0047] At present, in the application of the forming negative pressure cup, the electrolyte will flow back from the upper inlet and be discharged from the bottom outlet. During this reflux process, the electrolyte naturally falls on the bottom wall of the forming negative pressure cup and randomly collides, causing the electrolyte to splash on the side wall of the forming negative pressure cup. The splashing formed by the random collision cannot effectively form a secondary flushing, and crystallization will form over time, which will in turn affect the cleaning of the forming negative pressure cup and the normal application of the system.
[0048] In view of the above technical problems, the present embodiment mainly provides a formation negative pressure cup and a formation system, which can reduce the crystallization frequency in the formation negative pressure cup when the electrolyte refluxes, and can facilitate the cleaning of the formation negative pressure cup.
[0049] like Figure 1-8 As shown, a formation negative pressure cup provided according to some embodiments of the present application comprises a negative pressure cup body 1 and a guide plate 2; wherein, a liquid inlet 11 and an inner cavity 12 are provided on the negative pressure cup body 1, and the liquid inlet 11 is communicated with the inner cavity 12, and can be used to supply liquid into the inner cavity 12 when the electrolyte refluxes or the cleaning liquid is used for cleaning; the guide plate 2 is arranged in the inner cavity 12, and along the liquid entry direction, is arranged in front of the liquid inlet 11, so as to guide the liquid input at the liquid inlet 11 to the inner wall of the inner cavity 12.
[0050] By setting the liquid inlet 11, it is convenient to realize the electrolyte reflux into the inner cavity 12; and by setting the guide plate 2, the refluxed electrolyte and cleaning liquid can be guided, so that after the electrolyte or cleaning liquid enters from the liquid inlet 11, it flows down from the inner wall of the inner cavity 12 under the action of the guide plate 2, so that in each reflux of the electrolyte, or the flushing process of the cleaning liquid entering from the liquid inlet 11, the inner wall of the inner cavity 12 can be flushed, thereby reducing the frequency of crystallization in the formation negative pressure cup due to the reflux of the electrolyte, and the cleaning operation can also be more convenient.
[0051] As one application example, the side of the guide plate 2 facing the liquid inlet 11 is arranged in an arc shape, for example, forming an arched or spherical structure. Figure 2 shown.
[0052] By arranging the side of the guide plate 2 facing the liquid inlet 11 to be in the form of an arc surface, the flow of the liquid input at the liquid inlet 11 can be better facilitated, and the flushing ability of the liquid on the side wall of the inner cavity 12 can be improved.
[0053] As an application example, a guide groove 21 is further provided on the side of the guide plate 2 facing the liquid inlet 11 .
[0054] The guide groove 21 is provided to further guide the input liquid, so that after the liquid falls on the guide plate 2, it can flow out more evenly from all sides, thereby achieving uniform flushing of the side wall of the inner cavity 12.
[0055] In some embodiments, the number of the guide groove 21 can be set to one. In this case, the guide groove 21 is spirally arranged on the surface of the guide plate 2. Figure 3 shown.
[0056] By arranging the guide groove 21 in a spiral form, after the liquid falls on the guide plate 2, a swirl state can be formed along the guide groove 21, thereby achieving a decentralized flushing effect.
[0057] In some embodiments, the number of the guide grooves 21 may also be set to two or more. In this case, the guide grooves 21 are arranged around the center line of the guide plate 2. Figure 4 , 5 shown.
[0058] like Figure 4 At this time, the plurality of guide grooves 21 can be arranged in the form of concentric circles and arranged on the guide plate 2 to achieve layer-by-layer diversion of the liquid.
[0059] like Figure 5 At this time, a plurality of guide grooves 21 may be provided, and the plurality of guide grooves 21 may form a form centered on the center line and diffuse outward.
[0060] In some embodiments, in a scheme where a plurality of the guide grooves 21 are provided, each or part of the guide grooves 21 may be provided in a curved form, such as a spiral shape.
[0061] By arranging the guide grooves 21 around the center line of the guide plate 2 , after the liquid falls on the guide plate 2 , a more uniform dispersion effect can be formed along the guide grooves 21 .
[0062] As one application example, the shape of the guide plate 2 is adapted to the cross-sectional shape of the inner cavity 12 , and a reserved gap 22 is provided between the guide plate 2 and the wall surface of the inner cavity 12 .
[0063] By setting the shape of the guide plate 2 to be compatible with the cross-sectional shape of the inner cavity 12, the application adaptability between the guide plate 2 and the inner cavity 12 can be improved, thereby improving the flushing effect.
[0064] As one application example, the negative pressure cup body 1 includes an upper cup body 13 and a lower cup body 14, wherein the upper cup body 13 and the lower cup body 14 cover each other to form the inner cavity 12; the liquid inlet 11 is provided on the upper cup body 13, and the liquid outlet 15 is provided on the lower cup body 14. Liquid is input into the inner cavity 12 from the liquid inlet 11 and output from the liquid outlet 15.
[0065] In some embodiments, the guide plate 2 is disposed inside the upper cup body 13 .
[0066] In some embodiments, the guide plate 2 may also be disposed inside the lower cup body 14 .
[0067] In some embodiments, the guide plate 2 and the upper cup body 13 or the lower cup body 14 are formed as an integral structure. Figure 2 shown.
[0068] By providing the upper cup body 13 and the lower cup body 14 , it is easy to install and set the guide plate 2 in the negative pressure cup body 1 , which is more convenient to use.
[0069] As an example of an application, the places where the electrolyte flows can be optimized using smooth and corrosion-resistant materials.
[0070] In some embodiments, the smooth and corrosion-resistant material may be polytetrafluoroethylene.
[0071] In some embodiments, the guide plate 2 and / or the negative pressure cup body 1 are made of polytetrafluoroethylene material.
[0072] In some embodiments, a structural layer made of polytetrafluoroethylene material is provided on the surface of the guide plate 2 and / or the wall surface of the inner cavity 12 .
[0073] By configuring the guide plate 2 and / or the negative pressure cup body 1 to be made of polytetrafluoroethylene material, or forming a polytetrafluoroethylene structural layer on the guide plate 2 and / or the inner cavity 12, the adhesion of the electrolyte to the wall of the guide plate 2 and the inner cavity 12 can be reduced during reflux, thereby reducing the frequency of crystallization formation.
[0074] As one application example, the connection between the guide plate 2 and the negative pressure cup body 1 can be any one of press-fitting, snap-fitting or screw-fitting.
[0075] In some embodiments, Figure 6 As shown, when a press-fit installation method is adopted, a connecting portion 23 is extended outward on the guide plate 2. During installation, the connecting portion 23 is overlapped and placed on the lower cup body 14, and then the connecting portion 23 and the guide plate 2 are fixed by the connection between the upper cup body 13 and the lower cup body 14.
[0076] In some embodiments, Figure 7 As shown, when a snap-fit installation method is adopted, a groove 141 can be set on the inner wall of the lower cup body 14. During installation, the connecting portion 23 is snapped into the groove 141 and fixed through the connection between the upper cup body 13 and the lower cup body 14.
[0077] In some embodiments, the groove 141 may be disposed on the lower cup body 14 and / or the upper cup body 13 .
[0078] In some embodiments, Figure 8 As shown, when a screw-on installation method is adopted, the shape of the inner cavity 12 and the guide plate 2 can be set to be circular. At this time, a connecting thread or a screw-on clamping structure can be provided between the connecting portion 23 and the lower cup body 14 or the upper cup body 13 to directly install the guide plate 2 on the lower cup body 14 or the upper cup body 13.
[0079] By designing the connection method between the guide plate 2 and the negative pressure cup body 1, the installation connection between the guide plate 2 and the negative pressure cup body 1 can be easily achieved.
[0080] On the other hand, this embodiment also provides a formation system, in which at least one formation negative pressure cup as described above is arranged.
