[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] like Figure 1-Figure 7 The full-heat fresh air blower with disinfection and sterilization air purification function shown in the figure includes a fresh air blower housing 1, a cover plate 2 is hingedly provided on the fresh air blower housing 1, an outdoor air inlet pipe 102 and an outdoor air outlet pipe 103 are connected and fixedly provided on one side of the fresh air blower housing 1 in a symmetrical structure, an indoor air inlet pipe 104 and an indoor air outlet pipe 105 are connected and fixedly provided on the other side of the fresh air blower housing 1 in a symmetrical structure, a fifth air vent 106 is connected and fixedly provided on one side of the fresh air blower housing 1 close to the outdoor air inlet pipe 102, and a full heat exchanger is fixedly provided in the fresh air blower housing 1 Core body 3, multiple partitions 4 are fixedly installed in the fresh air fan casing 1, multiple foam ceramic plates 5 are placed in the fresh air fan casing 1, a disinfection and sterilization module 6 is placed in the fresh air fan casing 1, multiple installation mechanisms 7 are rotatably connected in the fresh air fan casing 1, an adjustment switch sealing plate 8 is rotatably connected in the fresh air fan casing 1, one end of the adjustment switch sealing plate 8 is fixedly connected to a motor 801, starting the adjustment switch sealing plate 8 can realize the switching between the internal and external circulation modes, and conical rubber plugs 802 are fixedly connected on both sides of the adjustment switch sealing plate 8.

[0021] When making the foam ceramic plate 5, the foam ceramic plate 5 is immersed in an aqueous solution of the composite catalyst for 10 hours to allow the composite catalyst to fully enter the pores of the foam ceramic plate 5 and cover the surface of the pores. The foam ceramic plate 5 is then placed in a drying oven at a high temperature of 400 degrees and dried for 2 hours to evaporate the water in the composite catalyst attached to the pore surface of the foam ceramic plate 5, thereby allowing the composite catalyst to adhere to the foam ceramic plate 5.

[0022] The composite catalyst used in the fresh air blower has the functions of disinfection, sterilization, and air purification. The composite catalyst includes AB-24 nano-functional material and air catalyst catalytic material. The mass ratio of AB-24 nano-functional material to air catalyst catalytic material in the composite catalyst is 1:1-1:10. The air catalyst catalytic material includes nano-grade titanium dioxide, titanium dioxide phosphate, silver ion antimicrobial agent, and deionized water. Specifically, the air catalyst catalytic material is 5-20wt% nano-grade titanium dioxide, 5-20wt% titanium phosphate, 5-20wt% silver ion antimicrobial agent, and deionized water. The fresh air blower has a plasma disinfection function.

[0023] The AB-24 nano-functional material and air catalyst catalytic material used in the present invention each have good sterilization and air purification effects. The reason for choosing to use the two in combination instead of using one of the materials alone for sterilization and air purification is mainly based on the fact that the combination of the two has more comprehensive functions, shorter action time and better effect.

[0024] like Figure 4 As shown, one side of the cover plate 2 is hinged to the fresh air fan housing 1 through two hinges 201, and one side of the cover plate 2 is fixedly connected with two hooks 202.

[0025] like Figure 3 As shown, the fresh air fan housing 1 is rotatably connected to the hook 202 and is provided with a buckle 101 , and the buckle 101 is overlapped with the hook 202 .

[0026] like Figure 5 As shown, the disinfection and sterilization module 6 includes a placement frame 601, in which a high-efficiency HEPA spray coating 602, a composite catalyst particle layer 603, and an activated carbon fiber layer 604 are sequentially placed. A honeycomb panel 605 is fixedly mounted within the composite catalyst particle layer 603, which contains composite catalyst particles. A retaining screen 606 is fixedly mounted on both sides of the honeycomb panel 605. The high-efficiency HEPA spray coating 602 is a composite catalyst spray solution sprayed onto the surface of the HEPA screen, the composite catalyst particle layer 603 is a composite catalyst particle filled in the honeycomb panel 605, and the activated carbon fiber layer 604 is made of highly active carbon fibers.

[0027] like Figure 6As shown, the mounting mechanism 7 includes a threaded rod 701, which is rotatably connected to the inner wall of the fresh air fan housing 1. One end of the threaded rod 701 is fixedly connected to a universal joint 702, and the other end of the universal joint 702 is rotatably connected to the fresh air fan housing 1. A turning handle 703 is fixedly connected to the universal joint 702, and a slider 704 is threadedly connected to the threaded rod 701. The slider 704 is slidably matched with the inner wall of the fresh air fan housing 1, and a U-shaped clip 705 is fixedly connected to the slider 704. The U-shaped clip 705 abuts against the placement frame 601 and the outer wall of the foam ceramic plate 5.

[0028] like Figure 3 As shown, a plurality of slots 401 are formed on one end of the partition plate 4 close to the full heat exchange core 3 , and the inner walls of the slots 401 are in sliding contact with the placement frame 601 and the outer walls of the foam ceramic plate 5 .

[0029] Working principle: When using the device, the foam ceramic plate 5 and the disinfection and sterilization module 6 need to be installed in the fresh air fan housing 1, and then the cover plate 2 is opened, and then the foam ceramic plate 5 and the disinfection and sterilization module 6 are respectively inserted into the card slot 401 on the partition 4, and then the threaded rod 701 connected to the universal joint 702 is rotated, so that the threaded rod 701 drives the U-shaped card plate 705 connected to the slider 704 to move, and the foam ceramic plate 5 and the disinfection and sterilization module 6 are limited and fixed, and then the cover plate 2 is closed and fixed with the buckle 101 and the hook 202; When ventilation is needed, the motor 801 is used to drive the regulating switch sealing plate 8 to rotate, so that the regulating switch sealing plate 8 is blocked at the fifth air vent 106. At this time, outdoor air enters through the outdoor air inlet pipe 102. By using the foam ceramic plate 5 coated with the composite catalyst as the primary filter, not only can pollutants such as dust and particulate matter be filtered, but then the air passing through the full heat exchange core 3 enters the disinfection and sterilization module 6, and is disinfected and sterilized in sequence by the high-efficiency HEPA spray layer 602, the composite catalyst particle layer 603 and the activated carbon fiber layer 604, and then is injected into the room through the indoor air inlet pipe 104 to complete the indoor fresh air; When ventilation is not required and only indoor air purification is required, the motor 801 is used to drive the regulating switch sealing plate 8 to rotate so that the regulating switch sealing plate 8 is blocked at the outdoor air inlet pipe 102. At this time, indoor air enters through the fifth air ventilation hole 106. By using the foam ceramic plate 5 coated with a composite catalyst as the primary filter, not only can pollutants such as dust and particulate matter be filtered, but the air then passes through the full heat exchange core 3 and enters the disinfection and sterilization module 6. It is disinfected and sterilized and the air is purified in sequence through the high-efficiency HEPA spray layer 602, the composite catalyst particle layer 603 and the activated carbon fiber layer 604, and then injected into the room through the indoor air inlet pipe 104 to complete the internal purification and sterilization of the indoor air.
