As shown in fig. 9, a plurality of inclined holes 340 are formed in the second baffle 34 in the circumferential direction.

As shown in fig. 13-14, the beam-converging assembly 5 includes a threaded rod 53, collars 52 disposed at two ends of the threaded rod 53, and a threaded pipe 51 sleeved outside the threaded rod 53 and in threaded engagement with the threaded rod 53, one end of the collar 52 is fixedly connected with one end of the threaded rod 53, the other end of the collar 52 is provided with a sleeve 521, the sleeve 521 is sleeved outside the threaded rod 53, and two ends of the threaded pipe 51 are respectively abutted against the two sleeves 521.

As shown in fig. 1-2, two collars 52 are respectively sleeved on the outer sides of the first joint 221 and the second joint 41.

The third joint 31 is connected to a fluid supply device (not shown) and when the fluid supply device is activated, fluid will flow from the third joint 31 into the second receiving assembly 33 and into the interior of the filter cartridge 231 of the filter element 23 through the fourth through-hole 330 and the inlet 201.

In some of these embodiments, the filter cartridge 231 is made using an ultrafiltration membrane.

It will be appreciated that after the fluid enters the interior of the cartridge 231, the impurities in the fluid are not allowed to pass through the cartridge 231 and enter the cavity 2101, and finally flow out of the flow channel 22, and the fluid is purified.

When the threaded pipe 51 in the converging assembly 5 is rotated, the threaded pipe 51 is transversely displaced relative to the threaded rod 53 due to the threaded engagement with the threaded rod 53, and when the threaded pipe 51 is transversely displaced, a pushing force is applied to one of the sleeves 521, and the pushing force of the other sleeve 521 is gradually withdrawn relative to the other sleeve 521; so that the pushed sleeve 521 tightens its corresponding collar 52 along the threaded rod 53, while the other sleeve 521 is progressively displaced along the threaded rod 53 so that its corresponding collar 52 relaxes.

Plugging the second through hole 4302 by the first baffle 44, and penetrating the first through hole 4301; the second baffle 34 is far away from the fourth through hole 330, and the fourth through hole 330 is communicated.

If the threaded tube 51 of the convergence assembly 5 is adjusted, the collar 52 over the second joint 41 is tightened and the collar 52 over the first joint 221 is loosened.

At this time, fluid is injected into the ultrafiltration purifier, the fluid is difficult to flow out of the ultrafiltration purifier in a short time due to the tightening of the second joint 41, the amount of fluid remaining in the ultrafiltration purifier increases along with the continuous injection of the fluid, the pressure of the fluid increases, the fluid rapidly penetrates through the filter cartridge 231 under the action of the pressure of the fluid and finally flows out of the flow channel 22, in the process, the collar 52 sleeved on the first joint 221 is loosened, the binding force of the first joint 221 is reduced, and when the fluid flows through from the inside of the first joint, the elastic strip 2211 is slightly outwards opened due to the influence of the pressure, namely, the opening of the first joint 221 at this time becomes large, and the fluid can flow out of the ultrafiltration purifier through the first joint 221 more rapidly.

Namely, the ultrafiltration purifier improves the filtration efficiency of the fluid, and after the filtration efficiency of the fluid is improved, the amount of the fluid instantaneously flowing out of the first connector 221 becomes large, and at the moment, the first connector 221 with the enlarged opening can adapt to the flow increase, so that a large amount of filtered fluid can be ensured to quickly flow out of the ultrafiltration purifier.

The fluid pressure value in the first cavity 2101 measured by the first pressure sensor 24 is uploaded to the control end, the fluid pressure value in the filter cartridge 231 measured by the second pressure sensor 25 is uploaded to the control end, and the two pressure values are compared.

Since the ultrafiltration purifier is used for a long time, clogging easily occurs on the inner wall of the filter cartridge 231 due to too many impurities being filtered.

At this time, fluid is injected into the ultrafiltration purifier, and the fluid is difficult to permeate through the filter cartridge 231 and flow out of the ultrafiltration purifier, so that the fluid amount in the filter cartridge 231 is increased, and the fluid in the first cavity 2101 is only small, and at this time, the ratio of the two pressure values measured by the first pressure sensor 24 and the second pressure sensor 25 is reduced, and a threshold value having a certain value of the ratio of the two pressure values is set in the control end.

When the cartridge 231 is severely blocked, the ratio will exceed the threshold, and the control end will control the second 35 and first 45 telescopic rods to retract, driving the second baffle 34 to block the fourth 330 through hole, and the first baffle 44 to block the first 4301 through hole and the second 41 through joint.

At this time, when the fluid enters the accommodating component two 33 from the joint three 31, the fluid can only flow into the ultrafiltration purifier through the inclined holes 340 on the baffle two 34 because the through hole four 330 is blocked by the baffle two 34, at this time, the total amount of the fluid is unchanged, the fluid will stay in the accommodating component two 33 for a longer time, the flow wave in the accommodating component two 33 finally becomes larger, the fluid flow velocity flowing into the filter cartridge 231 from the inclined holes 340 finally becomes faster, and the fluid will be flushed towards the inner wall of the filter cartridge 231 because of the restriction of the inclined holes 340, i.e. the fluid velocity at this time becomes faster, the direction is towards the inner wall of the filter cartridge 231, and the inner wall of the filter cartridge 231 can be efficiently flushed.

The flushed fluid will flow into the first receiving unit 43 through the side port 203 and eventually be redirected to the third port 420 to flow out by the plugging of the first port 4301 and the second joint 41.

By using the method to clean the impurity clogging inside the ultrafiltration purifier, the good functionality of the ultrafiltration purifier is ensured, and the fluid after cleaning the clogging does not flow through the second connector 41, so that the pollution to the inside of the second connector 41 is avoided.

While the foregoing is directed to the preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. The technical scope of the present invention is not limited to the description, but must be determined according to the scope of claims.
