Therefore, the capillary holes 61 can be uniformly distributed in the circumferential direction of the accommodating cavity 4, and the periphery of the accommodating cavity 4 is ensured to have better water absorption capacity.
It can be understood that, when the capillary holes 61 are arranged, the above two modes can be combined, so that the water absorption capacity of the waterproof structure 6 is better, and the waterproof effect is better.
In one possible embodiment, the diameter of the capillary openings 61 is between 40 and 60 μm. The diameter may be 40 μm, 50 μm or 60 μm. When the diameter is less than 40 μm, the difficulty of processing the capillary 61 increases. Since the capillary action is related to the diameter of the capillary pores 61 and the capillary action adsorbs less moisture as the diameter is larger, when the diameter is larger than 60 μm, the moisture adsorption capacity of the capillary pores 61 is reduced. In practical applications, the diameter of the capillary hole 61 can be selected according to practical applications within the above range, which is not limited by the embodiments of the present application.
It should be noted that the capillary 61 can be disposed in the following two ways:
in one possible embodiment, the capillary openings 61 are located on one of the two sides of the engagement surface 53. As shown in fig. 9, the capillary hole 61 may be located on the first engagement portion 51. As shown in fig. 10, the capillary hole 61 may also be located on the second engagement portion 52. Thus, the capillary 61 is provided only on one side of the joint surface 53, and the difficulty in processing the capillary 61 can be reduced.
In another possible implementation, as shown in fig. 3, a plurality of first capillary holes 611 are provided on the first joint 51, a plurality of second capillary holes 612 are provided on the second joint 52, and both the openings of the first capillary holes 611 and the openings of the second capillary holes 612 are located on the joint surface 53 of the first joint 51 and the second joint 52. Therefore, more capillary holes 61 can be arranged in a limited space, the arrangement density of the capillary holes 61 can be improved to the maximum extent, the water vapor absorption capacity of the waterproof structure 6 is maximized, and the waterproof effect of the waterproof structure 6 is better.
Specifically, as shown in fig. 3, the first capillary holes 611 and the second capillary holes 612 may be arranged in a staggered manner, so that water vapor on more areas of the joint surface 53 can be directly adsorbed by the capillary holes 61, and the water absorption range of the waterproof structure 6 on the joint surface 53 is increased. In addition, as shown in fig. 4, the first capillary holes 611 and the second capillary holes 612 may be arranged in a one-to-one correspondence, so that the openings of the first capillary holes 611 and the openings of the second capillary holes 612 are located at the same position of the joint surface 53, so that the openings of the capillary holes 61 have a greater water absorption capacity.
It should be noted that in the present embodiment, the capillary holes 61 are blind holes, that is, the closed ends of the capillary holes 61 are located in the first protective layer 1 or the second protective layer 3, and different capillary holes 61 are not communicated with each other on the side away from the joint surface 53. Thus, the difficulty of processing the capillary 61 can be reduced.
In one possible embodiment, as shown in fig. 11, the different capillary holes 61 may communicate on the side away from the bonding surface 53 through the communication holes 613, so that when the water vapor distribution on the bonding surface 53 is uneven, that is: some regions have more moisture and other regions have less moisture. Steam can flow from the position with high steam density to the position with low steam density through the capillary holes 61, so that the region with more steam on the joint surface 53 can have continuous water absorption capacity, the water absorption capacity saturation of the region with more steam is avoided to the maximum extent, and the dynamic water absorption capacity on the joint surface 53 is improved.
In one possible embodiment, as shown in fig. 3, the bonding surfaces 53 of the first bonding part 51 and the second bonding part 52 are located at the same level as at least part of the surface of the polarizing layer 2. Specifically, a containing groove may be formed in the first protection layer 1, the containing groove has a containing cavity 4, the polarizing layer 2 is located in the containing groove, and after the polarizing layer 2 is placed, the surface of the polarizer 100 away from the first protection layer 1 side is flush with the joint surface 53, as shown in fig. 2A and 2B, the thickness a of the polarizing layer 2 is equal to the depth B of the containing cavity 4. Therefore, on one hand, the structure of the second protection layer 3 is simplified, the setting difficulty of the second protection layer 3 is reduced, and on the other hand, the polarizer 100 is convenient to assemble. Similarly, a containing groove may be formed in the second protection layer 3, the containing groove has a containing cavity 4, the polarizing layer 2 is located in the containing groove, and after the polarizing layer 2 is placed, the surface of the polarizer 100 away from the second protection layer 3 is flush with the joint surface 53.

In another possible embodiment, the bonding surfaces 53 of the first bonding part 51 and the second bonding part 52 and the surface of the polarizing layer 2 may be located on different horizontal planes. As shown in fig. 5, in particular, the bonding surfaces 53 of the first bonding portion 51 and the second bonding portion 52 are located on the side of the polarizing layer 2 close to the second protective layer 3. The first protective layer 1 may be provided with a receiving groove, the receiving groove has a receiving cavity 4, the polarizing layer 2 is located in the receiving cavity 4, the thickness a of the polarizing layer 2 is smaller than the depth B of the receiving cavity 4, and a part of the second protective layer 3 is embedded in the receiving groove. Like this, can increase the distance between the surface of composition surface 53 and polarisation layer 2, wherein, steam from composition surface 53 entering back, need change flow direction and flow after one section distance, could contact with polarisation layer 2 to increase steam and pass through the path that composition surface 53 got into holding chamber 4 from the outside, the transmission degree of difficulty of increase steam reduces the possibility that steam corrodes polarisation layer 2.
It is understood that the bonding surfaces 53 of the first bonding portions 51 and the second bonding portions 52 may be located on the side of the polarizing layer 2 close to the first protective layer 1, that is: the second protection layer 3 is provided with a containing groove, the containing groove is provided with a containing cavity 4, the polarizing layer 2 is positioned in the containing cavity 4, the thickness of the polarizing layer 2 is smaller than the depth of the containing cavity 4, and part of the first protection layer 1 is embedded into the containing groove. The specific arrangement mode can be selected according to actual needs, and the arrangement mode of the accommodating groove is not limited in this embodiment.
The engagement surface 53 may be provided in the following two ways:
in one possible embodiment, as shown in fig. 3 and 4, the joining surfaces 53 of the first joining portion 51 and the second joining portion 52 may be flat surfaces. Thus, the difficulty of disposing the first engaging portion 51 and the second engaging portion 52 can be reduced.
In another possible embodiment, the joining surfaces 53 of the first joining portion 51 and the second joining portion 52 are uneven. Through making the composition surface 53 unsmooth, can increase steam and get into the route of holding chamber 4 through composition surface 53 from the outside, the transmission degree of difficulty of increase steam reduces the possibility that steam corrodes polarisation layer 2. Specifically, as shown in fig. 6, the engagement surface 53 may be a serrated surface. As shown in fig. 7, the engagement surface 53 may be curved. The embodiment of the present application does not limit the setting manner of the engaging surface 53, and the user can select the engaging surface according to the actual situation.
As shown in fig. 8, the bonding surface 53 may be a folded surface, wherein a blocking portion 11 is provided on a side of the polarizing layer 2 close to the bonding portion 5, and a surface of the blocking portion 11 close to the second protective layer 3 forms a part of the bonding surface 53. In this way, the joint surface 53 is formed by two surfaces with a height difference therebetween, and the moisture first passes the joint surface 53 on the joint portion 5 and then needs to rise to the joint surface 53 on the barrier portion 11 in the course of flowing. This increases the difficulty of the water vapor transmission during the flow process, thereby reducing the possibility of water vapor attacking the polarizing layer 2.
In one implementation, the first protective layer 1 and the second protective layer 3 may be made of the same material, the first protective layer 1 and the second protective layer 3 may include Tri-cellulose Acetate (TAC), and the polarizing layer 2 may include Polyvinyl Alcohol (PVA).
