A plurality of second recessed structures 242 arranged around the second accommodating cavity 250 are arranged on the inner bottom wall of the first accommodating cavity 240 of the bracket 20; after assembly, the second recessed structures 242 define a second gap between the inner bottom wall of the first accommodating cavity 240 and the second surface 520 of the first liquid-conducting element 50, so as to buffer the liquid matrix seeping from the second surface 520 of the first liquid-conducting element 50. The length of the second recessed structure 242 is greater than the width, and the width is greater than the depth.

[0102] according to Figures 7 to 10 As shown, an air inlet passage is arranged on the bracket 20 to provide a passage for the air from the air inlet 22 to enter the second accommodating cavity 250. The complete air inlet passage includes:

[0103] The first channel portion 23 extends from the air inlet 22 along the longitudinal direction of the bracket 20 or penetrates into the groove 222 on the surface of the second support portion 220; the external air entering from the air inlet 22 passes through the first channel portion 23 and is released into the groove 222;
