Description

Technical Field

[0001] This utility model relates to the field of household air purifier technology, specifically an air purifier based on MOF material. Background Technology

[0002] Formaldehyde is a colorless, highly irritating gas widely present in various indoor and outdoor environments. Indoors, formaldehyde mainly originates from building materials, furniture, decorative materials, and household items. During home renovations, various building materials release formaldehyde. Formaldehyde is a harmful gas; long-term exposure can cause symptoms such as dizziness, headaches, tearing, nausea, and vomiting, and in severe cases, may lead to conditions like leukemia. Therefore, for respiratory health, it is necessary to remove formaldehyde from indoor air and improve indoor air quality, leading to the development of air purifiers.

[0003] Currently, most air purifiers on the market use activated carbon to adsorb and remove formaldehyde, which results in insufficient formaldehyde removal. Using MOF (Metal-Oxide-Foil) materials, which have a strong adsorption capacity for formaldehyde, offers higher formaldehyde removal efficiency than traditional activated carbon adsorption. Formaldehyde adsorption is unaffected by ambient temperature and humidity, leading to higher air quality after purification.

[0004] To address the aforementioned issues, an air purifier based on MOF materials is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an air purifier based on MOF material, which solves the problem that most air purifiers on the market rely on activated carbon to adsorb and remove formaldehyde, resulting in insufficient formaldehyde removal. Utilizing MOF material, which has a strong adsorption capacity for formaldehyde, provides higher formaldehyde removal efficiency than traditional activated carbon adsorption. Furthermore, formaldehyde adsorption is unaffected by ambient temperature and humidity, leading to higher air quality after purification.

[0010] As a further description of the above technical solution: a turbine fan is fixedly connected to the top middle of the air purifier body.

[0011] By adopting the above technical solution, the motor and turbine fan are driven by electrolysis to rotate the turbine fan, which draws the compressed air around the air purifier into the air channel inside the air purifier.

[0012] As a further description of the above technical solution: the inner walls of the front and rear ends of the left side of the air purifier body are fixedly connected with fixing buckles.

[0013] The above technical solution facilitates installation.

[0014] As a further description of the above technical solution: MOF material filling layer bottom grooves are provided at both the front and rear ends of the left bottom of the MOF material filling layer, and a HEPA filter layer is provided on the top of the MOF material filling layer.

[0016] As a further description of the above technical solution: a bottom groove for the HEPA filter layer is provided on the top left side of the HEPA filter layer, and a pre-filter layer is provided on the top of the HEPA filter layer.

[0017] By adopting the above technical solution, the pre-filter layer intercepts and filters large particles, dust, lint, hair, and debris in the inhaled air.

[0018] As a further description of the above technical solution: a pre-filter bottom groove is provided on the top left side of the pre-filter layer, and a front cover plate is provided on the top of the pre-filter layer.

[0028] 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.

[0029] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0030] Reference Figure 1 This utility model discloses an air purifier based on MOF material, comprising an air purifier body 1, an air purification outlet mask 2 at the bottom of the air purifier body 1, and an air detector 3 fixedly connected to the inner left wall of the air purification outlet mask 2. The air detector 3 adopts advanced sensor technology and can detect various indicators of the air passing through it in real time and accurately, such as air quality level and pollutant concentration. It is like the "eyes" of the air purifier, constantly monitoring the air condition and providing important data support for subsequent purification operations.

[0031] Reference Figure 1 A display screen 16 is fixedly connected to the top right side of the air purifier body 1. The display screen 16 uses high-definition display technology to clearly and intuitively present the data detected by the air detector 3 to the user. Users can use the display screen 16 to understand the current indoor air quality and the working status of the air purifier in real time, facilitating monitoring and operation of the device. A filter fixing groove 5 is located inside the left side of the air purifier body 1. A filter fixing slot 15 is fixedly connected to the top right side of the air purifier body 1. An air purifier base 17 is located at the bottom of the air purifier body 1. The filter fixing groove 5 is designed to securely install and fix the relevant filter components, ensuring the stability and reliability of the filtration process. Simultaneously, a filter fixing slot 15 is fixedly connected to the top right side of the air purifier body 1. The filter fixing slot 15 and the filter fixing groove 5 cooperate to provide a reliable installation structure for the filter components, preventing them from loosening or shifting during operation.

[0032] Reference Figure 1The air purifier body 1 has a filter assembly on its top, which includes a MOF material filling layer 14. MOF material (metal-organic framework) has a unique porous structure and strong adsorption properties, enabling it to efficiently adsorb harmful gases, odor molecules, and fine particulate matter from the air. It acts like a "super sponge," quickly and massively capturing harmful substances from the air, reducing the burden on subsequent filtration steps. The MOF material filling layer 14 is located on the top of the air purifier body 1, and a turbine fan 4 is fixedly connected to the middle of the top of the air purifier body 1. The turbine fan 4 is driven by a high-performance motor, generating powerful suction to quickly draw surrounding air into the air purifier. It is the power source for the air to flow throughout the purification system, ensuring that the air can pass smoothly through each filter layer to achieve a highly efficient purification process. The air purifier body 1 has fixed hooks 6 on the inner walls of the front and rear ends on the left side. The MOF material filling layer 14 has MOF material filling layer bottom grooves 7 on the front and rear ends of the bottom left side. The MOF material filling layer 14 is equipped with a HEPA filter layer 13 on top. The HEPA filter layer 13 has a HEPA filter layer bottom groove 8 on the top left side. It can effectively filter out more than 99.97% of particles with a diameter greater than 0.3 microns in the air, such as dust, pollen, bacteria, and viruses. The top left side of the HEPA filter layer 13 has a bottom groove 8 for the HEPA filter layer, which is also for the purpose of achieving a stable connection with other components. This ensures that the HEPA filter layer 13 can always be kept in the correct position during the operation of the air purifier and exert its best filtration effect. The top of the HEPA filter layer 13 is provided with a pre-filter layer 12, and the top left side of the pre-filter layer 12 has a bottom groove 9 for the pre-filter layer. The top of the pre-filter layer 12 is provided with a front cover plate 11. The middle of the front cover plate 11 has evenly distributed air inlet mesh openings 10. The design of the air inlet mesh openings 10 not only ensures that air can enter the air purifier smoothly, but also provides preliminary blocking of the incoming air to prevent larger debris from entering the device and damaging other components. Meanwhile, the uniform distribution of the air inlet mesh 10 allows air to enter each filter layer evenly, improving the overall efficiency of air purification. In addition, the three filter layers are of the same size, which can seal the air channel well. The air drawn in must pass through the pre-filter layer, HEPA layer and MOF material filling layer in sequence for filtration and purification before it can be sent out to the air purifier. There is no situation where untreated air escapes from the gaps in the filter layers.

[0033] Working principle: When the air purifier is working, the turbine fan 4 rotates under electrolytic drive, drawing in surrounding air through the air inlet mesh 10. The air first passes through the pre-filter layer 12 to intercept large particulate impurities, then the HEPA filter layer 13 adsorbs fine particulate matter, and finally the MOF material filling layer 14 removes harmful gases such as formaldehyde. The purified air is discharged from the purified air outlet mask 2. The air detector 3 monitors the formaldehyde content and particulate matter concentration in the purified air in real time and transmits the information to the display screen 16 for display.
