[0038] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] like Figures 1-2 , Figures 6-7 , Figures 17-18 As shown, the present invention provides a prefabricated ventilated wall component for an assembled building, including a wall panel 1, which includes an inner wall 11, an insulation layer 12 and an outer wall 13 from indoors to outdoors in sequence, a plurality of vertical pipes 21 are fixedly arranged in the insulation layer 12, and a plurality of oblique pipes 22 arranged along the axis direction of the vertical pipes 21 are also arranged between two vertical pipes 21, the vertical pipes 21 are connected with the oblique pipes 22, and the vertical pipes 21 and the oblique pipes 22 form a ventilation pipe network 2; in this way, the entire ventilation pipe network 2 can be spread throughout the wall panel 1, and the "ribs" inside the wall panel 1 can be used to strengthen the strength and stability of the wall panel 1. At the same time, it can also prevent heat from gathering in a certain part of the wall panel 1 due to the ventilation structure. During ventilation, the entire ventilation airflow can flow in the entire ventilation pipe network 2, so that the heat is evenly distributed on the wall panel 1. When the heat exchange is more intense, the airflow in the ventilation pipe network 2 will condense on the pipe wall. At this time, the condensed water droplets can flow out along the pipe walls of the vertical pipe 21 and the inclined pipe 22. Therefore, the inner wall of the ventilation pipe network 2 needs to be provided with a rust-resistant and corrosion-resistant coating. Furthermore, according to the flow direction of air from outdoor to indoor during ventilation, such as Figures 15-16 As shown, the outer wall 13 is provided with a plurality of external vents 131 cooperating with the vertical pipes 21 near the bottom, so that the ventilation pipe network 2 is connected to the outside, and a detachable external ventilation assembly 4 is arranged in the external vent 131; specifically, as Figures 12-13 As shown, the external ventilation assembly 4 includes an external plug-in block 41, and the external plug-in block 41 is provided with a ventilation cavity 411, and the ventilation cavity 411 is L-shaped. The ventilation cavity 411 is provided with a wind wheel 412 at one end that cooperates with the vertical pipe 21 to control the air flow direction during ventilation; Figures 2 to 5As shown, at this time, the wind wheel 412 rotates counterclockwise (a small motor for driving the wind wheel 412 to rotate is provided in the external plug-in block 41, which is not shown in the figure), thereby driving the outdoor air to flow into the room through the ventilation pipe network 2. At the same time, the corner of the ventilation cavity 411 is provided with a concave portion 413 for focusing light, so that when external light shines into the ventilation cavity 411, a heat source can be formed in the ventilation cavity 411, so that a "chimney effect" is formed in the ventilation cavity 411 and the vertical pipe 21 to assist the wind wheel 412 to accelerate the rapid flow of air. In order to strengthen this phenomenon, the concave portion 413 can also be replaced with other heat sources (not shown in the figure) as needed. The bottom of the ventilation cavity 411 is provided with a slope 414 that cooperates with the concave portion 413, and the slope 414 is evenly provided with guide grooves 415. This is to ensure that when the condensed water droplets flow down from the walls of the vertical pipe 21 and the inclined pipe 22 to the ventilation cavity 411, they will finally flow along the guide grooves 41 5 is discharged quickly; the external ventilation component 4 also includes an external plug-in board 42, on which an insect-proof light-transmitting net 421 is arranged, and an outflow net 422 is arranged in the gap between the bottom of the insect-proof light-transmitting net 421 and the bottom of the ventilation cavity 411, so that while ensuring that light can shine into the ventilation cavity 411, the inflow and outflow of air can be guaranteed, and at the same time, small insects outdoors can be prevented from entering the room from the ventilation cavity 411 and the vertical pipe 21, and the liquid quickly discharged from the guide groove 415 is discharged from the outflow net 422; further, the external plug-in block 41 is also provided with a functional groove 416 at one end cooperating with the vertical pipe 21, and a functional module is arranged in the functional groove 416. The functional module can set the function of processing air (such as activated carbon, desiccant or humidification device, etc.) according to the environment used by the ventilation wall without affecting the gas circulation; after the outdoor air passes through the external ventilation component 4, it will then enter the ventilation pipe network 2, and then enter the room. Before the outdoor air enters the room, such as Figures 15-16 As shown, the inner wall 11 is provided with a plurality of inner vents 111 cooperating with the vertical pipes 21 near the top, so that the ventilation pipe network 2 is connected with the room, and a detachable inner ventilation component 3 is provided in the inner vent 111, specifically, as Figures 8 to 11As shown, the internal ventilation component 3 includes an insert block 31, the insert block 31 has a ventilation channel 311 that cooperates with the vertical pipe 21, and the insert block 31 has a first module slot 312 and a second module slot 313 at one end of the ventilation channel 311 close to the room, a heating module is inserted in the first module slot 312, and an air purification module (such as a HEPA filter, activated carbon, etc.) is inserted in the second module slot 313, and the ventilation channel 311 is set in a trumpet shape near the indoor end; the internal ventilation component 3 also includes an inner insert plate 32, and the inner insert plate 32 is provided with a shutter 312 for controlling the air flow direction. 21, so that the fresh air flowing out of the ventilation network 2 will first enter the ventilation flow channel 311, and then pass through the first module slot 312 and the second module slot 313 in turn, and finally flow into the room through the shutter 321; the first module slot 312 and the second module slot 313 can also be provided with other functions as needed, which will not be repeated here; the above is based on the flow direction of air from outdoor to indoor during ventilation, and another case is based on the flow direction of air from indoor to outdoor during ventilation. At this time, the wind wheel 412 rotates clockwise, which allows the indoor air to flow to the outdoors through the ventilation network 2.

[0040] In the cases of these two air flow directions, the user can actively control the air flow direction as needed, and then the inner ventilation component 3 and the outer ventilation component 4 can also be taken out and adjusted, so that whether it is subsequent repair or maintenance, even targeted adjustments can be made according to different usage environments and needs, and the required modules can be increased, decreased or mutated to improve the adaptability and flexibility of the ventilation wall.

[0041] Preferably, it also includes an intelligent controller and a sensing module arranged indoors, the sensing module includes one or more of a temperature sensor, a humidity sensor, a carbon dioxide sensor, a PM10 sensor, and a PM2.5 sensor, the sensing module is connected to the intelligent controller to adjust the wind wheel 412, the heating module, and the air purification module through the intelligent controller; in this way, during the entire ventilation process, the sensing module can be used to specifically and finely sense the indoor air quality, and then the intelligent controller can be used to specifically control the internal ventilation component 3 and the external ventilation component 4 to circulate indoor and outdoor air. For example, when rapid ventilation is required, the rotation speed of the wind wheel 412 can be increased, and the air purification module can ensure the quality of the air leading to the room. When used in a cold environment, a heating module (such as a heating network) can be added to heat the air entering the room to ensure that warm outdoor air enters the room, or in a humid environment, the internal ventilation component 3 and the external ventilation component 4 can also be targeted. The drying module can be replaced selectively, or conversely, in a dry environment, the humidification module can be replaced or added in the inner ventilation component 3 and the outer ventilation component 4. The above are examples of some usage scenarios. In short, due to the modular design of the inner ventilation component 3 and the outer ventilation component 4 with the wall panel 1, the function of the entire ventilation wall can be designed and optimized specifically for the environment, and more intelligent control can be performed to make the indoor and outdoor air circulation more comfortable; further, it also includes a power supply module to power the inner ventilation component 3 and the outer ventilation component 4. The power supply module uses natural energy, such as solar energy, wind energy, etc., and solar panels are set on the wall panel or on the top of the building, or a breeze power generation device is set on the top of the building, etc.; and then by wiring in the wall panel 1 (such as arranging wiring harness ducts in advance when prefabricating the wall panel 1, etc., conventional means, no longer repeated), so that energy can be provided to the above-mentioned parts to ensure the overall ventilation and energy-saving effects.

[0042] Preferably, Figure 1 As shown, a top connection portion 14 is fixedly provided on the top of the wall panel 1, a tenon connection portion 15 is provided at one end of the wall panel 1, and a mortise connection portion 16 cooperating with the tenon connection portion 15 is provided at the other end, so as to facilitate the connection between the wall panels during assembly; during assembly, the tenon connection portion 15 and the mortise connection portion 16 cooperate, and then concrete is poured into the gap for assembly.
