Further, since the first driving member 310 can drive the water lifting plate 320 to approach or separate from the hollow fiber membrane 230, the volume of the water accumulation chamber 1031 can be adjusted by controlling the position of the water lifting plate 320.
As shown in fig. 1, when the hollow fiber membrane module is in normal operation, the open/close valve 500 is in an open state, raw water enters the raw water chamber 102 through the water inlet 101 of the housing 100, and is then filtered by the hollow fiber membrane 230, the remaining water flows out through the first water passing port 221 and the sewage drain port 106, and the filtered water enters the pure water chamber 103 and is then discharged through the second water passing port 222 and the pure water port 107.

In addition, after the second driving member 400 drives the first fixing member 210 toward the second fixing member 220 until the first fixing member abuts against the water lifting plate 320, the hollow fiber membranes 230 can be in a loose state, and when the water lifting plate 320 moves toward the hollow fiber membranes 230, the hollow fiber membranes 230 can shake under the action of pure water, so that impurities adhered to the hollow fiber membranes 230 can be more easily washed away by the water. Thus, the hollow fiber membrane module can prevent the hollow fiber membrane 230 from being blocked by pollutants, prolong the service life of the hollow fiber membrane module, reduce the replacement frequency and save the cost.
It can be understood that, in the above, the hollow fiber membrane 230 is cleaned by using the filtered pure water, and compared with the manner of directly cleaning the hollow fiber membrane 230 by using the raw water, the cleaning effect is better.
As shown in fig. 1, in one embodiment, a limiting member 110 is further disposed on an inner wall of the housing 100, the limiting member 110 is disposed on a side of the first fixing member 210 away from the second fixing member 220, and the limiting member 110 is in limiting fit with the first fixing member 210.

The partition plate 600 is disposed in the second chamber and partitions the second chamber into the sewage chamber 104 and the filter chamber 105 such that the sewage chamber 104 is separated from the filter chamber 105. The sewage in the raw water cavity 102 can flow to the sewage cavity 104 through the first water passing port 221 and then is discharged through the sewage discharge port; pure water in the pure water chamber 103 can flow into the filter chamber 105 through the second water inlet 101 when the open/close valve 500 is opened, and can be discharged through the pure water inlet 107 after being further filtered in the filter chamber 105.
More specifically, the filter chamber 105 is a chamber body in which the filter member 700 is provided, and the filter member 700 is located between the second water passing port 222 and the pure water port 107.

The water entering the sewage chamber 104 through the first water passing port 221 has more pollutants, and the height of the guide surface 611 is gradually reduced from one side close to the first water passing port 221 to one side close to the sewage draining outlet 106, so that the pollutants can flow towards the sewage draining outlet 106, and the pollutants are prevented from being accumulated at an included angle between the partition plate 600 and the second fixing member 220.
Specifically, the sewage chamber 104 is located above the filter chamber 105, the first drainage port 221 is located on the left side of the sewage discharge port 106, the guide side 610 is the upper side surface of the partition 600, the guide surface 611 is formed on the left side portion of the guide side 610, and the height of the guide surface 611 decreases from left to right in sequence.

Further, the housing 100 is further provided with a water filling port 108, and the water filling port 108 is disposed opposite to the guide surface 611.
