Description

Technical Field

[0001] This utility model relates to a carbon-reducing air purifier, belonging to the field of air purifier technology. Background Technology

[0002] An air purifier is a device specifically designed to improve indoor air quality. Through its built-in filtration system, it effectively captures and removes various pollutants from the air. These pollutants include, but are not limited to, particulate matter, bacteria, viruses, smoke, and various harmful gases. By adsorbing, decomposing, or transforming these pollutants, air purifiers can significantly reduce the concentration of pollutants in the air, thus providing people with a healthier and more comfortable living and working environment. With modern people increasingly valuing a healthy quality of life, air purifiers have become an indispensable part of many homes and offices. They not only purify the air but also help alleviate allergy symptoms and improve overall quality of life.

[0003] China plans to reduce greenhouse gas emissions and promote the use of low-carbon technologies and clean energy.

[0004] Current air purifiers primarily rely on aerodynamic devices to drive airflow, membrane filters to intercept or adsorb pollutants, and electrical energy storage devices to maintain operation. Their function is limited to removing particulate matter or specific harmful gases from the air, completely lacking the ability to efficiently and selectively separate, actively enrich, and safely store energy-valuable gaseous components such as carbon dioxide. Their membrane filters only remove pollutants, exhibiting extremely low selective capture efficiency for carbon dioxide; the aerodynamic devices are only used for ventilation and circulation, unable to provide the necessary pressure or driving conditions for gas separation; and the electrical energy storage devices only ensure basic operation and cannot recover gas resources, resulting in the direct emission of carbon dioxide as waste, causing a huge waste of carbon resources. Furthermore, the complex fixing or disassembly structure in air purifiers makes filter replacement cumbersome and maintenance inconvenient. Utility Model Content

The separator body contains a carbon dioxide separation membrane, which includes an upper carbon dioxide separation membrane and a lower carbon dioxide separation membrane. The lower carbon dioxide separation membrane is connected to an inlet pipe and an outlet pipe, and the outlet pipe is connected to a negative ion generator. The upper carbon dioxide separation membrane is movably connected to the adsorption chamber through a carbon dioxide conduit inserted into the bottom of the adsorption chamber.

[0007] Furthermore, the front side of the main housing is connected to two symmetrically arranged front panel brackets. Each front panel bracket has a slot on its inner side. The front panel of the main housing is inserted into the slots on both sides through its two ends. The two front panel brackets are slidably connected to a first sealing base and a second sealing base.

The L-shaped first tenon and mortise buckle is provided with a tenon, and the second tenon and mortise buckle is provided with a mortise that matches the tenon.

[0008] Furthermore, the side of the wind-resistant slope opposite to the primary filter is a 1 / 4 elliptical arc slope.

[0009] Furthermore, the photocatalytic filter is equipped with an ultraviolet lamp connected to the electrical control box.

[0010] Furthermore, the upper-stage carbon dioxide separation membrane is a polydimethylsiloxane membrane, the lower-stage carbon dioxide separation membrane is a titanium dioxide ceramic membrane, and the membrane module is a polytetrafluoroethylene film.

[0012] The beneficial effects of this utility model are as follows: This utility model includes a silent fan, a pre-filter, a gentle slope, a photocatalytic filter, a HEPA filter, a carbon dioxide separator, a negative ion generator, and an adsorption chamber. The gentle slope is a 1 / 4 elliptical arc slope, which optimizes the airflow path and reduces airflow resistance and turbulence noise.

The carbon dioxide separator's carbon dioxide separation membrane combination includes an upper-stage carbon dioxide separation membrane using a polydimethylsiloxane (PDMS) membrane and a lower-stage carbon dioxide separation membrane using a titanium dioxide ceramic membrane, improving carbon dioxide separation efficiency and achieving staged selective permeation.

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings:

[0025] like Figure 1 , Figure 2 As shown, a carbon-reducing air purifier includes a main housing 31. The bottom, sides and top of the main housing 31 are provided with perforated plates 28. One side of the main housing 31 is movably connected to an adsorption chamber 12, and the other side of the main housing 31 is connected to an electrical control box 16. The electrical control box 16 is connected to a display screen 17.

[0026] The main housing 31 has two symmetrically arranged, adjustable-speed silent fans 1 installed on its lower sides. Each silent fan 1 has a pre-filter 2 connected to its inner side. Between the two pre-filters 2 in the lower middle part of the main housing 31, there is a gentle slope 3. The side of the gentle slope 3 opposite to the pre-filters 2 is a 1 / 4 elliptical arc slope. A photocatalytic filter 4 and a HEPA filter 6 are arranged in sequence above the gentle slope 3. The photocatalytic filter 4 is equipped with an ultraviolet lamp 5, which removes harmful microorganisms by irradiation. A carbon dioxide separator 15 is arranged above the HEPA filter 6, and a negative ion generator 14 is connected to the carbon dioxide separator 15.

[0027] Among them, the silent fan 1, the primary filter 2, the photocatalytic filter 4, the HEPA filter 6, the carbon dioxide separator 15, and the negative ion generator 14 are all sealed with EPDM rubber when combined with the main body 31.

[0028] like Figure 2, Figure 6 As shown, the carbon dioxide separator 15 includes a separator body, within which a carbon dioxide separation membrane assembly 8 is provided. The carbon dioxide separation membrane assembly 8 includes an upper-stage carbon dioxide separation membrane 21 and a lower-stage carbon dioxide separation membrane 20. The upper-stage carbon dioxide separation membrane 21 is a polydimethylsiloxane (PDMS) membrane, and the lower-stage carbon dioxide separation membrane 20 is a titanium dioxide ceramic membrane. The lower-stage carbon dioxide separation membrane 20 is connected to an inlet pipe 7 and an outlet pipe 9. The outlet pipe 9 is connected to a negative ion generator 14. The upper-stage carbon dioxide separation membrane 21 is connected to one end of a carbon dioxide conduit 10. The other end (terminal end) of the carbon dioxide conduit 10 is inserted into the bottom of the adsorption chamber 12. A first carbon dioxide sensor 29 is provided at the head of the carbon dioxide conduit 10, and a membrane assembly 11 is provided at the end of the carbon dioxide conduit 10. The membrane assembly 11 is made of polytetrafluoroethylene (PTFE) film, allowing only gas to pass through, while preventing liquid from passing through. The adsorption chamber 12 is filled with carbon dioxide adsorption material 18, which fills two-thirds of the volume of the adsorption chamber 12. An exhaust port 13 is provided at the top of the adsorption chamber 12, and a second carbon dioxide sensor 30 is provided on the exhaust port 13. The lower part of the adsorption chamber 12 is connected to a liquid recovery pipe 19. The first carbon dioxide sensor 29, the second carbon dioxide sensor 30, the carbon dioxide separator 15, the ultraviolet lamp 5, the silent fan 1, and the negative ion generator 14 are all connected to the electrical control box 16. The operation of each component is controlled by the control switch on the electrical control box 16. The first carbon dioxide sensor 29 and the second carbon dioxide sensor 30 transmit data to the display screen 17, which displays the difference between the two values. When the difference approaches zero, the composite material is considered to be carbon saturated.

[0029] like Figures 3-5 As shown, the front of the main housing 31 is connected to two symmetrically arranged front panel brackets 23. Each front panel bracket 23 has a slot on its inner side. The front panel 22 of the main housing is inserted into the slots on both sides through its two ends, thereby achieving the insertion with the two front panel brackets 23. A first sealing base 24 and a second sealing base 25 are slidably connected to the two front panel brackets 23, respectively. The first sealing base 24 is connected to an L-shaped first tenon and mortise fastener 26, and the second sealing base 25 is connected to an L-shaped second tenon and mortise fastener 27. The L-shaped first tenon and mortise fastener 26 is provided with a tenon 32, and the second tenon and mortise fastener 27 is provided with a mortise 33 that matches the tenon 32. When the tenon 32 is inserted into the mortise 33, the front panel 22 of the main housing is sealed.

[0030] In use, the control switch is turned on, and the silent fans 1 on both sides start. Air enters the main chamber 31 through the silent fans 1, passes through the pre-filter 2, and flows upward under the action of the wind ramp 3. The air then passes sequentially through the photocatalytic filter 4 irradiated by the ultraviolet lamp 5 and the HEPA filter 6, and then enters the air inlet pipe 7 of the carbon dioxide separator 15. Under the action of the carbon dioxide separation combination membrane 8 (including the lower carbon dioxide separation membrane 20 and the upper carbon dioxide separation membrane 21), air with a lower carbon dioxide concentration enters the air chamber through the outlet pipe 9 and the negative ion generator 14, while gas with a higher carbon dioxide concentration enters the adsorption chamber 12 through the carbon dioxide conduit 10 and adheres to the carbon dioxide adsorption material 18. Finally, the air is discharged into the external environment from the exhaust port 13. The two carbon dioxide sensors transmit data to the display screen, showing the difference between the two readings. When the difference approaches zero, the composite material is considered carbon saturated, and the carbon dioxide conduit 10 is manually removed from the adsorption chamber 12, separating the adsorption chamber 12 from the main chamber 31. Then, the adsorption chamber 12 is moved to a high-temperature environment of 100°C to desorb carbon dioxide, and then the carbon dioxide is discharged into a large gas collecting bottle through the exhaust port 13.

[0031] When replacing the filters, including the pre-filter 2, photocatalytic filter 4 and HEPA filter 6, move the L-shaped first tenon 26 and L-shaped second tenon 27 to both sides, and move the first sealing base 24 and the second sealing base 25 in the same direction. Then, remove the main housing front panel 22 from the main housing front panel slot 28 from bottom to top.

The above embodiments are merely descriptions of preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and improvements to the technical solutions of this utility model made by those skilled in the art without departing from the spirit of this utility model should fall within the protection scope defined by the claims of this utility model.
