[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-5 As shown, this utility model is a deep purification type negative ion air purification device, including a base 1, a housing 2 on top of the base 1, an air inlet 3 on one side of the lower end of the housing 2, a first fan 4 at the bottom inside the housing 2, the input end of the first fan 4 being connected to the air inlet 3 through an air inlet groove 5, the first fan 4 allowing air to enter the housing 2 through the air inlet 3 and the air inlet groove 5 when operating, a cover plate 6 is provided in the middle of the side wall of the housing 2 away from the air inlet 3, the lower part of the cover plate 6 being movably connected to the housing 2, allowing the cover plate 6 to rotate around the housing 2, U-shaped limiting plates 7 are provided on both sides of the cover plate 6 inside the housing 2, a support frame 8 is provided between the two U-shaped limiting plates 7, a metal filter 9 is inserted into the lower end of the support frame 8, the metal filter 9 can intercept large particulate pollutants such as hair and dust in the air, protecting the subsequent purification module from clogging, a HEPA high-efficiency filter layer 10 is provided above the metal filter 9, the HEPA high-efficiency filter layer 10 having a filtration accuracy of 0.3. The filter layer is micron-sized, with a filtration efficiency of over 99.97% for fine particulate matter such as PM2.5, bacteria, and viruses, effectively removing inhalable particulate matter and microorganisms from the air. Above the HEPA high-efficiency filter layer 10 is an activated carbon adsorption layer 11, filled with high-quality activated carbon particles. This layer has a rich microporous structure and a large specific surface area, capable of adsorbing harmful gases such as formaldehyde, benzene, and TVOC, as well as odorous substances, purifying the air of chemical pollution. Above the activated carbon adsorption layer 11 is a photocatalytic purification layer 12. Using nano-titanium dioxide as a catalyst, the photocatalytic purification layer 12 generates highly oxidizing free radicals under the irradiation of an ultraviolet lamp 13, decomposing residual harmful gases, bacteria, viruses, and other microorganisms in the air into carbon dioxide and water, achieving deep purification. (Metal filter 9, HEPA...) The high-efficiency filter layer 10, activated carbon adsorption layer 11, and photocatalytic purification layer 12 are all inserted into the support frame 8, making the filter components easy to install and disassemble. Ultraviolet lamps 13 are provided on both sides above the U-shaped limiting plate 7 inside the housing 2. A negative ion generator 14 is provided above the ultraviolet lamps 13 inside the housing 2. The negative ion generator 14 adopts high-voltage discharge technology, which can generate a large number of highly active, small-particle negative ions. These negative ions are released into the air through the air outlet, combine with pollutants in the air, and cause them to settle, thereby improving air quality and creating a fresh air environment like a forest. An air outlet 15 is opened in the middle of the upper part of the housing 2, through which purified air can be discharged.

[0020] The housing 2 is equipped with a second fan 16 located below the air outlet 15. When the second fan 16 is working, it can discharge fast airflow.

[0021] The cover plate 6 is movably connected to the housing 2 at the bottom, and a groove 17 is provided at the upper end of the cover plate 6. The groove 17 makes it easier to open and close the cover plate 6.

[0022] The cover plate 6 is provided with a first magnet 18 on both sides of the upper end. The housing 2 is provided with a second magnet 19 that matches the first magnet 18. The first magnet 18 and the second magnet 19 have opposite poles facing each other. Through the cooperation between the first magnet 18 and the second magnet 19, the cover plate 6 can be stably fixed on the housing 2.

[0023] The U-shaped limiting plate 7 is provided with a sealing gasket 20 on the side near the support frame 8. The sealing gasket 20 can seal the contact surface between the U-shaped limiting plate 7 and the support frame 8. The setting of the sealing gasket 20 effectively ensures the filtration effect of the filter components inside the support frame 8.

[0024] The housing 2 is equipped with a control panel 21 located above the air inlet window 3. The control panel 21 can control the working status of the purification equipment.

[0025] Specifically, in this invention, when the first fan 4 is operating, air enters the housing 2 through the air inlet window 3 and the air inlet slot 5. As the airflow passes through the filter assembly, the metal filter screen 9 intercepts large particulate pollutants such as hair and dust in the air, protecting the subsequent purification module from clogging. The HEPA high-efficiency filter layer 10 has a filtration efficiency of up to 99.97% for fine particulate matter such as PM2.5, bacteria, and viruses. The above effectively removes inhalable particulate matter and microorganisms from the air. The activated carbon adsorption layer 11 is filled with high-quality activated carbon particles, which can adsorb harmful gases such as formaldehyde, benzene, and TVOC, as well as odor substances, purifying the air of chemical pollution. The photocatalytic purification layer 12 uses nano titanium dioxide as a catalyst. Under the irradiation of ultraviolet lamp 13, it generates free radicals with strong oxidizing properties, which decompose residual harmful gases, bacteria, viruses and other microorganisms in the air into carbon dioxide and water, achieving deep purification. The negative ion generator 14 adopts high-voltage discharge technology, which can generate a large number of highly active, small-particle negative ions. These negative ions are released into the air through the air outlet, combine with pollutants in the air, and cause them to settle, thereby improving air quality and creating a fresh air environment like a forest. The purified air can be discharged through the air outlet 15. The metal filter 9, HEPA high-efficiency filter layer 10, activated carbon adsorption layer 11 and photocatalytic purification layer 12 are all inserted into the support frame 8, making the filter components easy to install and disassemble.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
