[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1: A waterproof and moisture-proof exterior wall tile solves the problem that when exposed to prolonged rain, rainwater may seep into the interior of the exterior wall tile, causing it to become damp and resulting in poor waterproofing. By using a drainage channel 3, the waterproofing of the exterior wall tile body 1 is improved. The following is disclosed:
[0032] A decorative panel 2 is attached to the top of the exterior wall brick body 1; a drainage groove 3 is provided on the top of the exterior wall brick body 1, a ventilation groove 4 is provided in the middle of the exterior wall brick body 1, and a guide groove 5 is provided at the bottom of the exterior wall brick body 1. The ventilation groove 4 is trapezoidal in shape and is perforated.
[0033] refer to Figures 1 to 4 When it rains, rainwater flows through the drainage channel 3, allowing it to drain from the surface of the exterior wall brick body 1. Rainwater that enters the interior of the exterior wall brick body 1 is discharged through the ventilation channel 4, enabling rapid drainage. Furthermore, the guide channel 5 guides rainwater on the wall surface, preventing rainwater from accumulating inside the exterior wall brick body 1. This results in good waterproofing and moisture-proofing for the exterior wall brick body 1.
[0034] Example 2: A waterproof and moisture-proof exterior wall tile solves the problem of existing tiles not being replaceable according to needs. The use of positioning blocks 6 facilitates the replacement of decorative panels 2, thereby improving adaptability. The following is disclosed:
[0035] A positioning block 6 is fixed to the left end of the exterior wall brick body 1, and the positioning block 6 and the limiting groove 7 form a locking and limiting mechanism. The limiting groove 7 is opened at the right end of the exterior wall brick body 1. A bolt 8 is slidably connected through the middle of the decorative panel 2, and the bottom of the bolt 8 extends into the interior of the connecting block 9 to form a threaded connection. The connecting block 9 is fixed inside the exterior wall brick body 1. A locking block 10 is fixed to the bottom of the decorative panel 2, and the bottom of the locking block 10 extends into the interior of the locking groove 11 to form a limiting mechanism. The locking groove 11 is opened at the top of the exterior wall brick body 1.
[0036] refer to Figures 1 to 5When it is necessary to disassemble the decorative panel 2, use a tool to turn the bolt 8, which will then disengage from the connecting block 9 and the interior of the decorative panel 2. This allows the decorative panel 2 to be separated from the exterior wall brick body 1. The movement of the decorative panel 2 will cause the locking block 10 to disengage from the slot 11. To replace the required decorative panel 2, the locking block 10 extends into the slot 11, which can then position the decorative panel 2. Then, the bolt 8 is screwed into the connecting block 9, which will then fix the decorative panel 2 to the exterior wall brick body 1. This allows for replacement according to different needs, thereby improving adaptability. Furthermore, during installation, by inserting the positioning block 6 into the limiting groove 7, the exterior wall brick bodies 1 can be spliced together, thereby improving the stability of the splicing of the exterior wall brick bodies 1.
[0037] Example 3: A waterproof and moisture-proof exterior wall tile solves the problem that existing exterior wall tile bodies 1 are prone to rainwater adsorption, resulting in poor waterproofing. The waterproofing of the exterior wall tile body 1 is improved by using a hydrophobic layer 101. The following is disclosed:

The bottom of the hydrophobic layer 101 is provided with a sound insulation layer 102, which is composed of rock wool material and is located inside the exterior wall brick body 1. The bottom of the sound insulation layer 102 is provided with a heat insulation layer 103, which is composed of polystyrene board material and is located inside the exterior wall brick body 1.
[0039] refer to Figure 1 and Figure 6 The use of the hydrophobic layer 101 allows the exterior wall brick body 1 to have good drainage, thereby preventing rainwater from adhering to the surface of the exterior wall brick body 1 and thus preventing rainwater from eroding into the interior of the exterior wall brick body 1. The use of the sound insulation layer 102 can reduce noise, thereby preventing noise from being transmitted through the exterior wall brick body 1, thus improving the comfort of use. The use of the heat insulation layer 103 can prevent the high temperature caused by sunlight, thereby isolating heat and thus improving the comfort of use of the exterior wall brick body 1.
[0040] Working principle: When using this type of waterproof and moisture-proof exterior wall tile, firstly, refer to... Figures 1 to 4 When it rains, rainwater flows through the drainage channel 3, while rainwater that enters the interior of the exterior wall brick body 1 is discharged through the ventilation channel 4. Furthermore, the drainage channel 5 can also guide the rainwater on the wall surface, thereby giving the exterior wall brick body 1 a good moisture-proof effect.
[0041] refer to Figures 1 to 5When it is necessary to disassemble the decorative panel 2, use a tool to turn the bolt 8, so that the bolt 8 can be disengaged from the connecting block 9, and then the decorative panel 2 can be separated from the exterior wall brick body 1. Replace the required decorative panel 2 by inserting the locking block 10 into the slot 11, and then screwing the bolt 8 into the connecting block 9, so that the decorative panel 2 can be fixed on the exterior wall brick body 1, thereby improving adaptability. Furthermore, during installation, by inserting the positioning block 6 into the limiting groove 7, the stability of the splicing of the exterior wall brick body 1 is improved.
[0042] refer to Figure 1 and Figure 6 The use of the hydrophobic layer 101 allows the exterior wall brick body 1 to have good drainage, thereby preventing rainwater from eroding the interior of the exterior wall brick body 1. The use of the sound insulation layer 102 can reduce noise, thus improving the comfort of use. The use of the heat insulation layer 103 can isolate heat, thus improving the comfort of use of the exterior wall brick body 1.
