In addition, during filter structure 230 are set, since the setting of filter plate 231 is open in lid 220 and first
Between 212, and filter plate 231 is to be removably disposed between lid 220 and the first opening 212, and the purpose is to be convenient for being somebody's turn to do
The maintenance of vacuum cylinder 200, in addition, to be replaced to filter plate 231, so that mistake under different use conditions
Filter plate 231 can filter varigrained sand or different size of sundries.Secondly, the filter plate in setting above content
When 231, filter plate 231 can be multiple, and the granularity for the sand that can be filtered between multiple filter plates 231 is different, by
This can further increase the effect of filtering by multistage filtering.
Further, it in the utility model embodiment, between filter plate 231 and the first opening 212 and filters
Sealing ring (not shown) is equipped between plate 231 and lid 220.The leakproofness of junction can be increased by sealing ring,
It prevents the case where leak occur in junction, avoids leading to the pressure transient in vacuum cylinder 200 due to leak, thus adsorption capacity
The case where larger fluctuation occur occurs.
In the other embodiments of the utility model, filter structure 230 can also include setting in connection first through hole 222
And the strainer (not shown) on the pipeline of vacuum pump.By the way that strainer is arranged on the pipeline of first through hole 222 and vacuum pump,
Filtering sand can equally be played the role of, sand is avoided the occurrence of and enter in vacuum pump, influence the normal use of vacuum pump.Its
Outside, it should be noted that when using the embodiment of filter plate 231 is arranged between the first opening 212 and lid 220, equally
Strainer, and the filtering sand of strainer and filter plate 231 can also be set on the pipeline of connection first through hole 222 and vacuum pump
Granularity it is different, multistage filtering is consequently formed, further increases the effect of filtering.
Further, in the present embodiment, lid 220 is using spherical lid 220, when lid 220 and cylinder 210 are matched
When conjunction, second chamber (not shown) can be formed between filter plate 231 and lid 220, and by the second opening 213
Water into first chamber 211 needs to pass through second chamber before entering vacuum pump through the first opening 212.On the contrary, logical
When crossing immersible pump and being filled the water into vacuum pump, since the second through-hole 223 is arranged on lid 220, therefore by immersible pump to the vacuum
The water injected in cylinder 200 can first pass around second chamber, then go through first chamber 211 and be discharged from the second opening 213,
Play the role of discharging the adhesive force of vacuum cylinder 200.In this process, since the effect of filter plate 231 is filtering sand, therefore its
During the filtration process, can have an impact to the flow of water, based on reduction filter plate 231 influence during discharging adhesive force
Purpose, is additionally provided with filling pipe group (not shown) in vacuum cylinder 200, filling pipe group include first pipe (in figure not
Show) and second pipe (not shown).Wherein, first pipe is for first chamber 211 to be connected to the second through-hole 223；
Second pipe is for second chamber to be connected to the second through-hole 223.It can effectively guarantee to dive by above-mentioned filling pipe group
The normal work of water pump, while by reducing filter plate 231 to its stream to water when filling the water by immersible pump into vacuum cylinder 200
The influence of amount can effectively ensure that the vacuum cylinder 200 can timely discharge adhesive force, improve the speed of reaction.
Further, in the other embodiments of the utility model, cylinder 210 can also be by multiple identical daughters (in figure
It is not shown) it is composed.By the daughter number of selection composition cylinder 210, the height of cylinder 210 can be adjusted, with
So that the vacuum cylinder 200 can adapt to the application demand of different depth conditions.
It should be noted that in the other embodiments of the utility model, when cylinder 210 includes at least two daughter,
Filter structure 230 may include the filter plate 231 being arranged between two neighboring daughter.By being arranged between adjacent daughter
Filter plate 231 can further increase the effect of filtering.Outside it, sealing ring is equipped between filter plate 231 and daughter.
Further, in the other embodiments of the utility model, a kind of vacuum cylinder 200 is additionally provided, and it is above-mentioned
The structure of vacuum cylinder 200 is substantially the same, the difference is that: lid 220 is equipped with mounting portion 221 and via hole (in figure
