[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4As shown, a heating and ventilation device capable of purifying air includes a housing 1. One end of the housing 1 is provided with an air inlet, and the top of the other end is provided with an exhaust pipe 2. A filter assembly is installed inside the housing 1. A heating assembly is installed inside the exhaust pipe 2. A protective net 13 is installed at the air inlet. An inspection port is provided at the end of the housing 1 away from the air inlet. A cover 14 is installed at the inspection port. A PLC controller 15 is installed on the side of the housing 1.

[0022] The housing 1 is equipped with a U-shaped positioning seat 3. The positioning seat 3 has three mounting slots on its inner side, in which a pre-filter 4, a HEPA filter 5, and an activated carbon filter 6 are respectively installed. A UV lamp strip 7 is embedded between two mounting slots on the inner side wall of the positioning seat 3. A through groove is formed on the top of the housing 1 above the positioning seat 3. A cover plate 16 is installed above the through groove. The bottom of the cover plate 16 is provided with a sealing gasket that abuts against the top of the positioning seat 3.

[0023] The pre-filter 4 primarily intercepts particles larger than 5 micrometers in diameter, such as dust, pet hair, and fibrous debris. By blocking large particles, it prevents the HEPA filter 5 and activated carbon filter 6 from becoming clogged, thus extending their lifespan. The HEPA filter 5 can capture particles with a diameter ≤0.3 micrometers, including PM2.5, pollen, bacteria, viruses, dust mites, and allergens. The activated carbon filter 6 effectively removes volatile organic compounds such as formaldehyde, benzene, and TVOC, as well as odors.

[0024] Under ultraviolet light, bacteria and viruses attached to the HEPA filter 5 and activated carbon filter 6 are eliminated, preventing them from surviving and multiplying.

[0025] Inside the housing 1, a partition 8 is fixed to one side of the positioning seat 3. A through hole is provided at the lower part of the partition 8, and a round tube 9 is installed on the side of the partition 8 outside the through hole. A fan 10 is installed inside the round tube 9. A photocatalyst mesh 17 is installed below the exhaust pipe 2 inside the housing 1, and a UV lamp 18 is provided below the photocatalyst mesh 17.

[0026] Under ultraviolet light, the photocatalyst network 17 can catalyze the decomposition of volatile organic compounds such as formaldehyde, benzene, and TVOC, converting them into harmless carbon dioxide and water. The strong oxidizing free radicals generated by the photocatalytic reaction destroy the cell structure of bacteria and viruses, achieving efficient sterilization.

[0027] Multiple guide plates 11 are installed alternately on both sides of the interior of the exhaust pipe 2, forming a serpentine channel. Multiple sets of heating wires 12 are installed between every two guide plates 11. A protective cover 19 is installed on the top of the exhaust pipe 2, and several ventilation holes are opened on the protective cover 19.

[0028] The serpentine channel and the arrangement of multiple heating wires 12 can enhance the heating effect of the air.

[0029] In practical use, the positioning seat 3 and the installation slot facilitate the disassembly and replacement of the pre-filter 4, HEPA filter 5 and activated carbon filter 6; the ultraviolet rays emitted by the UV lamp strip 7 can eliminate bacteria, viruses and other substances attached to the HEPA filter 5 and activated carbon filter 6; the photocatalytic mesh 17 and UV lamp 18 can further improve the sterilization effect of the air; and the serpentine channel and multiple sets of heating wires 12 can enhance the heating effect of the air.
