To guide the flow of glue, the cross-sectional area of the receiving groove is optionally tapered. In some embodiments, the width of the receiving groove is tapered to direct the flow of glue. In some embodiments, the depth of the receiving groove is tapered to direct the flow of glue. Depending on the size constraints of the reverse osmosis membrane sheet 2, a manner of width reduction or depth reduction may be selected to achieve a reduction in the cross-sectional area of the receiving tank.
Optionally, at least two holding grooves are arranged, and two adjacent holding grooves are communicated through an arc-shaped groove, so that the flowing resistance of glue between the two adjacent holding grooves can be reduced. In some embodiments, the accommodating groove is concavely arranged on the reverse osmosis membrane 2, and the processing cost is low. Alternatively, the accommodating groove is formed by pressing the reverse osmosis membrane 2, and the processing mode is simple. The holding tank can be a shallow indentation to avoid breaking the reverse osmosis membrane 2. In some embodiments, the reverse osmosis membrane 2 is provided with two protrusions, and a receiving groove is formed between the two protrusions, so that the structural strength of the reverse osmosis membrane 2 is prevented from being damaged.
Specifically, the accommodating grooves may be provided with three, which are a first accommodating groove 22, a second accommodating groove 23 and a third accommodating groove 24 which are sequentially communicated, the first accommodating groove 22 and the third accommodating groove 24 each extend along the length direction of the reverse osmosis membrane sheet 2, the second accommodating groove 23 extends along the width direction of the reverse osmosis membrane sheet 2, and the cross-sectional areas of the first accommodating groove 22 and the third accommodating groove 24 each decrease gradually along the direction away from the central tube 1. It will be appreciated that the width direction of the reverse osmosis membrane 2 is parallel to the axial direction of the central tube 1, and the length direction of the reverse osmosis membrane 2 is perpendicular to the axial direction of the central tube 1. Since the reverse osmosis membrane sheet 2 has a small thickness, the first, second and third accommodation grooves 22, 23 and 24 may be formed by punching the reverse osmosis membrane sheet 2.

Since the second receiving groove 23 is far from the central tube 1, the influence of glue aggregation at the central tube 1 is small, the second receiving groove 23 may be an equal-width groove, and the equal-width groove means that two groove side walls of the second receiving groove 23 are parallel. The second receiving groove 23 may be a straight line groove of equal width, and is parallel to the pair of folded edges 21. In order to avoid glue overflow due to local stress concentration caused by abrupt cross-section change, the minimum width of the first receiving groove 22 and the third receiving groove 24 is optionally greater than or equal to the width of the second receiving groove 23.
Alternatively, the depth values of the first accommodating groove 22, the second accommodating groove 23 and the third accommodating groove 24 are all in the range of 2mm to 4mm. The depth of the first, second and third receiving grooves 22, 23 and 24 should not be too small to avoid glue overflow. The depth of the first accommodating groove 22, the second accommodating groove 23 and the third accommodating groove 24 is not too large, so that the reverse osmosis membrane 2 is prevented from being damaged, and the filtration performance is prevented from being lost.

Alternatively, the first receiving groove 22 and the second receiving groove 23 are in transitional communication through the first arc-shaped groove 25. The design of the first arc-shaped groove 25 is beneficial to the smooth flow of the glue in the first accommodating groove 22 to the second accommodating groove 23, so that the glue overflow is avoided.
