[0031] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-9 A wall ecological greening module with air purification function is shown, including a planting box 1 and an induced draft box 2 fixedly connected thereto by bolts, a planting board 3 is fixedly connected to the front end of the planting box 1, the planting board 3 is provided with evenly distributed green plant cups 301, and the planting board 3 is provided with air outlet holes 302 located inside the green plant cups 301; the inner side of the planting board 3 is abutted with an outer geotextile 4, the inner side of the outer geotextile 4 is abutted with a plastic matrix 5, the inner side of the plastic matrix 5 is abutted with an inner geotextile 6, the inner side of the inner geotextile 6 is abutted with a mesh plate 7, the mesh plate 7 is provided with evenly distributed mesh holes 701, and a back cavity is formed between the mesh plate 7 and the inner wall of the planting box 1; the back cavity is connected to a cross-flow fan 12 arranged in the induced draft box 2;

[0034] For details, please refer to Figure 2 and Figure 8, start the cross-flow fan 12, which injects external air into the back cavity. When the airflow in the back cavity accumulates to form a certain wind pressure, the airflow penetrates into the plastic matrix 5 wrapped by the inner geotextile 6 and the outer geotextile 4 through the mesh 701 of the mesh plate 7. The porous structure of the plastic matrix 5 absorbs and filters impurities in the air, and finally the airflow is discharged through the air outlet 302 on the planting plate 3;

[0035] See also Figure 4 and Figure 5 A movable plate 8 is provided in the back cavity, which is slidably connected to the inner wall of the planting box 1. A plurality of puncture needles 10 arranged opposite to the mesh 701 are fixedly connected to the side wall of the movable plate 8 facing the mesh plate 7. A transverse driving mechanism 9 is connected to the side of the movable plate 8 away from the mesh plate 7. The transverse driving mechanism 9 drives the movable plate 8 to move back and forth transversely in the back cavity. When the movable plate 8 moves in the direction of the mesh plate 7, it drives the puncture needles 10 to be inserted into the plastic matrix 5;

[0036] For details, please refer to Figure 8 and Fig. 9 When in use, external air is injected into the back cavity of the planting box 1 through the cross-flow fan 12, generating wind pressure in the back cavity, and the external air passes through the plastic matrix 5 wrapped by the outer geotextile 4 and the inner geotextile 6, and the aerosol impurities in the external air are adsorbed by the porous structure of the plastic matrix 5, thereby achieving purification of the external air; at the same time, after a period of use, due to the accumulation of a large number of impurity particles in the pores of the plastic matrix 5, the air passing efficiency is affected, and the transverse driving mechanism 9 is started, and the transverse driving mechanism 9 drives the movable plate 8 and the puncture needle 10 thereon to move back and forth laterally. The puncture needle 10 is inserted back and forth into the plastic matrix 5 for many times to clear the pores of the plastic matrix 5 and increase the diffusion speed of the airflow in the plastic matrix 5. In addition, the movable plate 8 moves back and forth in the back cavity, squeezes the airflow in the back cavity, increases the wind pressure in the back cavity, and further improves the penetration speed and diffusion uniformity of the airflow in the plastic matrix 5.

[0037] It should be noted that the wall ecological greening module with air purification function of the present application can be spliced ​​and used, and the number of ecological greening modules can be set according to the actual area of ​​the green plant wall, which has good adaptability.

[0038] Compared with the traditional green planting cavity, the present invention injects external air into the planting box 1 through the induced draft box 2 with a cross-flow fan 12 and the planting box 1 with a back cavity, and makes the air flow through the plastic matrix 5 and then be discharged from the planting box 1 through the planting plate 3 and the mesh plate 7 arranged on both sides of the plastic matrix 5, and the aerosol impurities in the external air flow are adsorbed by the porous structure of the plastic matrix 5, so as to achieve the purification of the external air; at the same time, through the movable plate 8, the puncture needle 10 and the horizontal driving mechanism 9 arranged in the back cavity, the puncture needle 10 is reciprocatedly inserted into the plastic matrix 5, and the pores of the plastic matrix are squeezed and cleared, so as to improve the flow penetration effect of the air flow in the plastic matrix 5; in addition, the air flow in the back cavity is reciprocally squeezed by the movable plate 8, so as to improve the penetration pressure of the air flow in the back cavity, thereby improving the penetration efficiency and the uniformity of the air flow diffusion.

[0039] See also Figure 1 and Figure 4 The planting box 1 is provided with oppositely arranged drip grooves 102 on the shell walls on the upper and lower sides of the plastic matrix 5, and a plurality of equally distributed drip holes 103 are provided on the inner wall of the drip groove 102 close to the shaping matrix 5, and the orifices of the drip holes 103 are in contact with the plastic matrix 5.

[0040] Specifically, when multiple ecological greening modules are spliced ​​to form a green plant wall, only the drip irrigation pipe set above the topmost ecological greening module is needed for irrigation. The irrigation water flows through the drip grooves 102 and drip holes 103 set at different heights to seep down step by step. The water flows in the porous structure of the plastic matrix 5 to form a water curtain, further improving the adsorption and purification effect of the air.

[0041] See also Figure 2 and Figure 4 The planting box 1 is a hollow box with an opening at the front end. The planting plate 3 is fixedly connected to the front end shell wall of the planting box 1 by bolts. The induced air box 2 is a rectangular hollow box with a second air inlet slot 201 on the front end face. An air outlet slot 202 is provided on the side wall where the induced air box 2 and the planting box 1 abut against each other. The planting box 1 is provided with a first air inlet slot 101 arranged opposite to the air outlet slot 202.

[0042] See also Figure 2 and Figure 3 The first air inlet slot 101, the second air inlet slot 201 and the air outlet slot 202 are all vertical through slots. The cross-flow fan 12 includes a hood 1201, an impeller 1202 arranged in the hood 1201, and a second motor 1203 for driving the impeller 1202 to rotate. The hood 1201 is a vertical cylindrical structure, and its front end is connected to the second air inlet slot 201, and the right end of the hood 1201 is connected to the air outlet slot 202.

[0043] Specifically, the external air is sucked into the hood 1201 through the second air inlet slot 201 by the cross-flow fan 12 , and then injected into the back cavity through the air outlet slot 202 and the first air inlet slot 101 .

[0044] See also Figure 1 A door panel 13 is fixedly connected to the right side of the planting box 1 by bolts, and the inner wall of the door panel 13 is in contact with the plastic matrix 5 .

[0045] Specifically, the plastic matrix 5 is disassembled and replaced by opening the door panel 13 .

[0046] See also Figure 7 The transverse driving mechanism 9 is a linear telescopic cylinder, which can be an electric telescopic cylinder or a hydraulic telescopic cylinder. In addition, the transverse driving mechanism 9 can also adopt a crank slider mechanism. The driving slider mechanism includes a clamping frame 901 fixedly connected to the movable plate 8. The clamping frame 901 is slidably clamped with an eccentric groove disk 902. The eccentric groove disk 902 is fixedly connected with the output shaft of the first motor 903. The first motor 903 is fixedly connected to the inner wall of the planting box 1. The transverse driving mechanism 9 using the crank slider mechanism has better bearing capacity, so that the movable plate 8 has better stability when it moves back and forth laterally.

[0047] In this embodiment, the plastic matrix 5 is a block structure, and the plastic matrix 5 is one of a rock wool matrix, a phenolic resin matrix or a polyester fiber matrix.

[0048] Specifically, the porous structure of the plastic matrix 5 has a good adsorption effect on aerosol impurities in the external air.

[0049] See also Figure 5 and Figure 6 The puncture needle 10 is a round tube with a pointed front end. A sealing ring 11 is fixedly connected to the mesh hole 701 on the mesh plate 7 opposite to the puncture needle 10. A perforation is reserved on the inner geotextile 6 for the puncture needle 10 to pass through. A truncated cone-shaped center hole is opened in the center of the sealing ring 11.

[0050] Specifically, by providing the puncture needle 10 with a pointed front end, the puncture needle 10 is easier to insert into the plastic matrix 5, and by providing the sealing ring 11, the soil adhered to the surface of the puncture needle 10 during the removal process is scraped off to reduce the overflow of matrix particles.

[0051] Second implementation method:

[0052] Figure 4 , Figure 5 and Fig.10A wall ecological greening module with air purification function is shown. On the basis of the first embodiment, the puncture needle 10 is a hollow circular tube, and a uniformly distributed penetration hole 1001 is opened in the lower part near the tip. The side of the puncture needle 10 away from the tip is connected to a liquid supply mechanism, and the liquid supply mechanism includes a connecting tube 14 fixedly connected to the end of the puncture needle 10, and the connecting tube 14 is fixedly connected to a hard tube 15. The hard tube 15 is connected to an infusion pump 17 fixedly connected to the inner wall of the planting box 1 through a hose 16. The infusion pump 17 is connected to a liquid storage tank 18 fixed on the inner wall of the planting box 1 through a pipeline, and the liquid storage tank 18 is filled with microbial liquid.

[0053] Specifically, after the puncture needle 10 is inserted into the plastic matrix 5, the liquid supply mechanism injects the microbial liquid into the puncture needle 10, and the microbial liquid is injected into the plastic matrix 5 through the penetration hole 1001, so that the microbial liquid diffuses in the plastic matrix 5. At the same time, in conjunction with the reciprocating extrusion of the puncture needle 10 and the reciprocating extrusion and compression of the movable plate 8, the squeezed airflow accelerates the diffusion speed and uniformity of the microbial liquid in the plastic matrix 5, and the microbial liquid uniformly diffused in the plastic matrix 5 kills bacteria and viruses in the airflow flowing through the plastic matrix 5, thereby further improving the air purification effect.

[0054] In this embodiment, the microbial liquid includes at least one of Penicillium, Clostridium or Bacteroides.

[0055] Specifically, various bacteria and viruses suspended in the air are killed.

[0056] See also Figure 5 The penetration hole 1001 is an inclined hole, and its outer end opening is away from the tip direction of the puncture needle 10.

[0057] Specifically, during the process of inserting the puncture needle 10 into the plastic matrix 5 , the probability of the matrix particles blocking the penetration hole 1001 is reduced by the inclined penetration hole 1001 .

[0058] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
