Description

Technical Field

[0001] This utility model relates to the field of fresh air exchange equipment technology, specifically an antibacterial fresh air exchange machine. Background Technology

[0002] With the improvement of people's living standards and the increasing attention to a healthy living environment, indoor air quality has become a focus of attention. Fresh air exchangers, as an important device for improving indoor air quality, are widely used in various places. However, traditional fresh air exchangers have many problems in actual use. Due to the presence of a large number of bacteria, viruses and other microorganisms in the indoor environment, they attach to dust particles and spread indoors through airflow, threatening human health.

[0003] Ordinary fresh air exchangers only achieve simple air circulation and basic filtration, and cannot effectively inhibit or kill these microorganisms. This results in the introduction of bacteria and viruses from the outside world along with the fresh air. Furthermore, the filtration systems of traditional fresh air exchangers mainly focus on filtering larger particles of dust and other impurities, and are not very effective at filtering tiny bacteria, viruses, and harmful gases, making it difficult to meet people's demand for high-quality indoor air. Utility Model Content

[0004] The purpose of this invention is to provide an antibacterial fresh air exchanger to solve the problems mentioned in the background art, which are that fresh air exchangers only achieve simple air circulation and basic filtration, and cannot effectively inhibit or kill these microorganisms. Furthermore, the filtration systems of traditional fresh air exchangers mainly focus on filtering larger particles of dust and other impurities, and are not effective at filtering tiny bacteria, viruses, and harmful gases.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an antibacterial fresh air exchanger, including a main housing, which is configured as a rectangular structure. A sealing cover is installed at the opening of the main housing, and the sealing cover is penetrated by a drive motor. The drive motor is connected to the impeller inside the main fan. The main housing and the sealing cover constitute the main housing structure of the air exchanger, and the main fan and the drive motor constitute the air-powered ventilation drive in the air exchanger.

[0006] The main housing is equipped with a main fan, one end of which is connected to the collection bucket, and the collection bucket abuts against the side wall of the main housing. Filter screen one and filter screen two are respectively snapped together on both sides of the main housing, and filter screen one abuts against the bucket-shaped opening of the collection bucket, and filter screen one is connected to the mounting shell one.

[0007] The second filter screen is engaged with the surface of the second mounting shell, and the second nano-silver filter frame is installed inside the second mounting shell. The second mounting shell is engaged with the side surface of the main shell, and the other side surface of the main shell is engaged with the first mounting shell. A diverter plate is installed inside the main shell, and an ultraviolet lamp plate is provided at the upper end of the diverter plate. The ultraviolet lamp plate is connected to the surface of the sealing cover by bolts.

[0008] The above technical solution, with its multi-layer filtration design, can effectively filter dust, pollen, and other impurities in the air.

[0009] Preferably, a sealing element is provided at the connection between the main housing and mounting shell one and mounting shell two, and a barrier element is provided at the connection between the inner wall of the main housing and the main fan.

[0010] By adopting the above technical solution, the barrier at the connection between the inner wall of the main casing and the main fan can reduce air leakage and noise at the connection.

[0011] Preferably, the two ports of the main fan are respectively connected to both sides of the main casing, and the ports of the main fan are placed close to the diverter plate.

[0012] The above technical solution facilitates good air circulation, allowing air to pass smoothly through the filtration and antibacterial components, thereby improving air treatment efficiency.

[0013] Preferably, the mounting shell and the closing cover are engaged to form a rectangular box, and a nano-silver filter frame is engaged inside the mounting shell.

[0014] By adopting the above technical solution, the nano-silver filter can further inhibit the bacteria in the air passing through, thereby enhancing the antibacterial function of the air exchanger.

[0015] Preferably, the diverter plate consists of four plates, which are staggered and the diverter plate divides the space inside the main housing in an S-shape.

[0016] By adopting the above technical solution, the S-shaped flow channel extends the air flow path and residence time in the main housing, allowing the air to more fully receive the sterilization effect of the ultraviolet lamp plate and the antibacterial treatment of the nano-silver filter.

[0017] Preferably, both the second and first nano-silver filter frames consist of three layers of filter screens, and each layer of filter screen is coated with nano-silver ions.

[0018] Using the above technical solution, nano-silver ions are sprayed onto the surface of each filter layer to increase the contact area between air and nano-silver ions and improve antibacterial efficiency.

[0019] Preferably, the dimensions of the second mounting shell are the same as those of the first mounting shell and the closed cover, and the second mounting shell has a pipe opening on its surface, as does the closed cover.

[0020] By adopting the above technical solution, the consistent size of the housing facilitates unified design and installation, and also makes it convenient for users to replace and maintain filter components.

[0021] Compared with the prior art, the beneficial effects of this utility model are: This antibacterial fresh air exchanger:

[0022] 1. Filter screen one and filter screen two are respectively snapped together on both sides of the main shell, forming a multi-layer filtration structure in conjunction with nano-silver filter frame one and nano-silver filter frame two. Filter screen one can perform preliminary physical filtration on the incoming air, intercepting larger particulate impurities. Subsequently, when the air passes through nano-silver filter frame one, it not only achieves effective antibacterial effect, but also further filters out tiny particles. Similarly, the air exhausted from the room first passes through filter screen two for preliminary filtration, and then passes through nano-silver filter frame two for deep purification. Nano-silver filter frame one and nano-silver filter frame two are both composed of three layers of filter screens, and the surface of each filter screen is sprayed with nano-silver ions. Nano-silver ions have broad-spectrum antibacterial properties and can bind to the proteins on the surface of bacteria, viruses and other microorganisms, destroy their cell structure, inhibit the growth and reproduction of microorganisms, effectively filter dust, pollen and other impurities in the air, meet the needs of air purification, and improve indoor air quality.

[0023] 2. Two ducts of the main fan are connected to both sides of the main housing, and the ducts are placed close to the diversion plate. When the main fan is working, it can quickly guide the air to the diversion plate. The diversion plate consists of four staggered plates, which divide the space inside the main housing into an S-shape. This design increases the residence time of the air in the main housing, allowing the air to be fully irradiated and sterilized by the ultraviolet lamp plate. It also allows the air to have more contact with the nano-silver filter, improving the antibacterial and filtration effects. The second mounting shell is the same size as the first mounting shell and the closed cover, and all of them have ducts on their surfaces to ensure smooth airflow, optimize the overall air flow path, and improve the working efficiency of the equipment.

[0031] 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.

[0032] Please see Figures 1-6 This utility model provides a technical solution: an antibacterial fresh air exchanger, including a main shell 1, a sealing cover 2, a main fan 3, a drive motor 4, a central hopper 5, a filter screen 1 6, a nano-silver filter frame 1 7, a mounting shell 1 8, a closing cover 9, a diverter plate 10, an ultraviolet lamp plate 11, a filter screen 2 12, a nano-silver filter frame 2 13, and a mounting shell 2 14.

[0033] The main housing 1 is rectangular in shape. A sealing cover 2 is installed at the opening of the main housing 1. The sealing cover 2 is penetrated by the drive motor 4. The drive motor 4 is connected to the impeller inside the main fan 3. The main housing 1 and the sealing cover 2 constitute the main housing structure of the air exchanger. The main fan 3 and the drive motor 4 form the wind-powered air exchange drive in the air exchanger.

[0034] A main fan 3 is installed inside the main housing 1, and one end of the main fan 3 is connected to the centralized hopper 5. The centralized hopper 5 abuts against the side wall of the main housing 1. Filter screen 1 6 and filter screen 2 12 are respectively snapped together on both sides of the main housing 1. Filter screen 1 6 abuts against the bucket-shaped opening of the centralized hopper 5. Filter screen 1 6 is installed by connecting the main housing 1 with the mounting shell 1 8. A sealing element is provided at the connection between the main housing 1 and the mounting shell 1 8 and the mounting shell 2 14. A barrier element is provided at the connection between the inner wall of the main housing 1 and the main fan 3. The two pipe ports of the main fan 3 are respectively connected to the two sides of the main housing 1. The pipe ports of the main fan 3 are placed close to the diversion plate 10.

[0035] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the main housing 1 is connected to mounting housing 8 and mounting housing 14 on both sides to connect the indoor and outdoor spaces. One end of mounting housing 14 is connected to an external duct and is connected to the indoor ventilation duct. After the air enters the mounting housing 14 and undergoes initial air diversion and sterilization, the air that has been sterilized by ultraviolet light is drawn in by the main fan 3 and guided to the concentrator 5. The bucket-shaped structure of the concentrator 5 gathers the air and directs it to the filter screen 6 that is aligned with the bucket-shaped opening of the concentrator 5. When the air passes through the filter screen 6, it undergoes another physical filtration to intercept even smaller particulate impurities. Subsequently, the air enters the mounting housing 8 that is connected to the filter screen 6. The mounting housing 8 and the closing cover 9 are engaged to form a rectangular box. The nano-silver filter frame 7 inside the box is also composed of three layers of filter screens with nano-silver ions sprayed on the surface, which further inhibits the bacteria in the fresh air and ensures that bacteria and viruses in the fresh air are effectively suppressed.

[0036] Clean air, after being filtered and sterilized through multiple layers, is discharged through the ducts on the surfaces of mounting shell 8 and closed cover 9 and sent into the room to complete the fresh air exchange process. During operation, the sealing parts at the connection between the main shell 1 and mounting shell 8 and mounting shell 14 fit tightly to the connection points, effectively preventing air leakage at these locations and ensuring that air can only pass through the filtration and sterilization devices along a predetermined path, thus ensuring the equipment's working efficiency and purification effect. At the same time, the barrier at the connection between the inner wall of the main shell 1 and the main fan 3 prevents air from escaping from the connection point when the main fan 3 is working, maintaining stable airflow inside the equipment and ensuring good ventilation performance.

[0037] The filter screen 12 is engaged with the surface of the mounting shell 14, and a nano-silver filter frame 13 is installed inside the mounting shell 14. The mounting shell 14 is engaged with one side surface of the main shell 1, and the other side surface of the main shell 1 is engaged with the mounting shell 8. A diverter plate 10 is installed inside the main shell 1. The mounting shell 8 and the closing cover 9 are engaged to form a rectangular box, and a nano-silver filter frame 7 is engaged inside the mounting shell 8. An ultraviolet lamp plate 11 is provided at the upper end of the diverter plate 10. The diversion plate 10 is connected to the surface of the sealing cover 2 by bolts. It consists of 4 plates, which are staggered. The diversion plate 10 divides the space inside the main housing 1 in an S-shape. The nano-silver filter frame 2 13 and nano-silver filter frame 1 7 are both composed of three layers of filter screens, and each layer of filter screen is coated with nano-silver ions. The size of the mounting shell 2 14 is the same as the size of the box of mounting shell 1 8 and closing cover 9. The surface of mounting shell 2 14 and closing cover 9 are provided with openings.

[0038] Referring to the attached diagrams in the instruction manual Figures 1-6As shown, when the air exchanger starts, the drive motor 4 drives the main fan 3 to operate, generating suction. Outdoor air is drawn into the equipment through the pipe opening on the surface of the mounting shell 14. The nano-silver filter frame 13 inside the mounting shell 14 has nano-silver ions sprayed on the surface of its three-layer filter screen. It first exerts an antibacterial effect on the incoming air, initially inhibiting bacteria and viruses in the air. The nano-silver ions in the nano-silver filter frame 13 combine with the surface proteins of bacteria and viruses, destroying the microbial cell structure and reducing their activity.

[0039] Next, the air passes through the filter screen 12, which is engaged with the surface of the mounting housing 14. The filter screen 12 performs preliminary physical filtration, intercepting larger particles of dust, hair, and other impurities in the air, preventing these impurities from entering the equipment and affecting the normal operation of subsequent working components. It also reduces the burden on subsequent deep purification. The air that has passed through preliminary filtration and antibacterial treatment enters the main housing 1. The duct of the main fan 3 quickly guides the air to the diversion plate 10. The diversion plate 10 consists of four staggered plates that divide the space inside the main housing 1 into an S-shape. The air flows in this S-shaped path, greatly increasing the residence time. At this time, the ultraviolet lamp plate 11, which is connected to the surface of the sealing cover 2 by bolts at the upper end of the diversion plate 10, plays its role. The ultraviolet lamp plate 11 emits ultraviolet rays of a specific wavelength. As the air flows slowly through it, it fully irradiates the air, destroying the DNA structure of bacteria and viruses, achieving efficient sterilization, and further reducing the microbial content in the air.

[0040] Working Principle: When using this antibacterial fresh air exchanger, the electric drive motor 4 rotates, driving the impeller inside the main fan 3 to rotate and generate suction. At this time, outside air enters through the duct on the surface of the mounting shell 14, first passing through the nano-silver filter frame 13. The nano-silver ions sprayed on its surface can initially inhibit bacteria and other microorganisms in the air. Then the air enters the main shell 1 and is guided by the diversion plate 10. Since the diversion plate 10 is composed of 4 staggered plates, it divides the airflow and guides it in an S-shape, increasing the residence time of the air in the shell. At the same time, the ultraviolet lamp plate 11 emits ultraviolet rays, destroying bacteria and viruses. The NA structure further sterilizes the air. After initial filtration and sterilization, the air is drawn in by the main fan 3 and directed to the collection hopper 5. The collection hopper 5 gathers the air and directs it to the filter screen 6. As the air passes through the filter screen 6, it undergoes another physical filtration, intercepting tiny particles. The air then enters the mounting shell 8 and comes into contact with the nano-silver filter frame 7. The nano-silver ions exert their antibacterial effect again, further purifying the air. The clean air, after multiple layers of filtration and antibacterial treatment, is discharged through the surface openings of the mounting shell 8 and the closed cover 9 and sent into the room, completing the fresh air exchange process and increasing the overall practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
