[0002] Home air purifiers can intelligently monitor indoor air quality and adjust the purification mode in real time through intelligent sensors, thereby purifying indoor air. They are suitable for areas with frequent smog, newly renovated houses, families with mothers and infants, families with allergies, and enclosed office spaces. Existing air purifiers generally consist of an outer shell, sensors, air outlet, air inlet cover, fan, and filter.

[0003] Existing application number: CN202223112211.3. This utility model belongs to the field of air purifier technology, specifically relating to an air purifier, including a purifier body. A filter shell for filtering gas is fixedly installed in the center of the purifier body. A carbon dioxide reaction chamber for absorbing carbon dioxide gas is fixedly installed inside the purifier body and directly below the filter shell. An air intake mechanism for absorbing gas is installed inside the purifier body and on one side of the carbon dioxide reaction chamber. This utility model can treat indoor carbon dioxide gas, providing consumers with a good sleeping environment and solving the problem of increased carbon dioxide concentration caused by poor air circulation. Furthermore, during the process of the air intake fan, the exhaust pipe is automatically cleared, ensuring a good storage environment for sodium hydroxide solution and indirectly reducing the manufacturing cost of the air purifier.

[0004] Based on the above, as a core device for improving indoor air quality, the cleaning and maintenance of the filter of a household air purifier directly affects the purification effect and user experience. Traditional purifiers mostly rely on manual replacement of the filter periodically, lacking efficient automatic cleaning methods, resulting in high maintenance costs and short filter life, which greatly increases the cost of use. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an air filter monitoring and purification device. This addresses the issue that, as a core device for improving indoor air quality, the cleaning and maintenance of the filter in existing household air purifiers directly affects the purification effect and user experience. Traditional purifiers often rely on manual, periodic filter replacement, which results in high maintenance costs and short filter lifespan, significantly increasing operating costs.

[0006] The purpose and effectiveness of this utility model's air filter monitoring and purification device are achieved through the following specific technical means:

[0007] An air filter monitoring and purification device includes an air purifier body, an air outlet, an air inlet cover, a filter element, a fan, a converging port, a partition plate, a fixing bracket, pressure sensors, a purification component, and an anti-scattering component. The air outlet is fixedly connected to the top of the air purifier body. The air inlet cover is inserted into the right side of the air purifier body. The filter element is disposed inside the air purifier body. The fan is fixedly connected to the top of the air purifier body. The converging port is fixedly connected below the fan. The partition plate is fixedly connected to the bottom of the converging port. The fixing bracket is fixedly connected inside the converging port. Two pressure sensors are provided, and the two pressure sensors are separately fixedly connected to the fixing bracket. The purification component is disposed inside the air purifier body. The anti-scattering component is disposed inside the air purifier body.

[0008] Furthermore, the purification component includes: a filter screen; the filter screen is inserted into the converging port, and the filter screen has multiple filter holes inside.

[0009] Furthermore, the purification component also includes: a fixed box, a sliding plate, and an insertion plate; the fixed box is fixedly connected to the front of the convergence port; the sliding plate is slidably connected inside the fixed box; and the insertion plate is fixedly connected to the sliding plate.

[0010] Furthermore, the purification component also includes: a reset spring and a fixing plate; two reset springs are provided, with the tops of the two reset springs being fixedly connected to the bottom of the sliding plate and the bottoms of the two reset springs being fixedly connected to the inside of the fixing box; the fixing plate is fixedly connected to the front of the filter screen, and a square slot is provided inside the fixing plate.

[0011] Furthermore, the anti-scattering component includes: an enclosing adhesive tape; the enclosing adhesive tape has a U-shaped structure and is disposed inside the purifier body.

[0012] Furthermore, the anti-scattering component also includes: a hook and loop fastener and a hook and loop hook fastener; three hook and loop fasteners are provided, and the three hook and loop fasteners are respectively fixedly connected to the left and right sides and the rear of the surrounding adhesive tape; three hook and loop fasteners are provided, and the three hook and loop fasteners are dispersedly fixedly connected inside the purifier body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, when the pressure sensor detects abnormal air pressure in the filter element, the fan automatically reverses, driving the airflow to flow in the opposite direction from the air outlet of the purifier, and blowing the accumulated dust out of the filter element through the collection port, ensuring the filter element's effectiveness. At the same time, the filter screen adopts a quick-release structure, which can be disassembled and cleaned without tools, ensuring efficient filtration and convenient maintenance.

[0015] Secondly, the pressure-sensitive adhesive-coated cloth wrapping tape is used to efficiently adhere to impurities on the filter surface blown out by the back-blowing airflow during the filter purification process, preventing the impurities from being reabsorbed by the filter. The wrapping tape is fixed inside the purifier by a combination of Velcro velvet and Velcro hook sides, supporting quick disassembly for cleaning or replacement, balancing cleaning efficiency and maintenance convenience.

[0016] This invention utilizes wind pressure monitoring and reverse airflow cleaning technology. When the pressure sensor detects a clogged filter element, the fan automatically reverses to drive the airflow in the opposite direction to blow away the accumulated dust on the filter element. Combined with a pressure-sensitive adhesive-coated cloth wrapping tape, it effectively intercepts impurities blown back and allows for quick disassembly and cleaning via Velcro, extending the filter element's service life and forming a collaborative system for intelligent cleaning and convenient maintenance.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] Example 1:

[0029] As attached Figure 1 To be continued Figure 8 As shown:

[0030] This utility model provides an air filter monitoring and purification device, including an air purifier body 1, an air outlet 101, an air inlet cover 2, a filter element 3, a fan 4, a convergence port 5, a partition plate 6, a fixing bracket 7, pressure sensors 8, and purification components; the air outlet 101 is fixedly connected to the top of the air purifier body 1; the air inlet cover 2 is inserted into the right side of the air purifier body 1; the filter element 3 is disposed inside the air purifier body 1; the fan 4 is fixedly connected to the top of the air purifier body 1; the convergence port 5 is fixedly connected below the fan 4; the partition plate 6 is fixedly connected to the bottom of the convergence port 5; the fixing bracket 7 is fixedly connected inside the convergence port 5; two pressure sensors 8 are provided, and the two pressure sensors 8 are separately fixedly connected to the fixing bracket 7; the purification components are disposed inside the air purifier body 1.

[0031] The purification component includes: a filter screen 9; the filter screen 9 is inserted into the converging port 5, and the filter screen 9 has multiple filter holes inside.

[0032] The purification component also includes: a fixed box 10, a sliding plate 11, and an insertion plate 1101; the fixed box 10 is fixedly connected to the front of the gathering port 5; the sliding plate 11 is slidably connected inside the fixed box 10; and the insertion plate 1101 is fixedly connected to the sliding plate 11.

[0033] The purification component also includes: a reset spring 1102 and a fixing plate 901; two reset springs 1102 are provided, with the tops of the two reset springs 1102 being fixedly connected to the bottom of the sliding plate 11, and the bottoms of the two reset springs 1102 being fixedly connected to the inside of the fixing box 10; the fixing plate 901 is fixedly connected to the front of the filter screen 9, and a square slot is opened inside the fixing plate 901.

[0034] The specific usage and function of this embodiment are as follows: During use, outside air enters through the filter element 3. When it passes through the converging port 5, the pressure sensor 8 monitors the air pressure. If the air pressure is too low, it indicates that the filter element 3 is severely clogged. At this time, the fan 4 reverses, and outside air flows back into the purifier body 1 from the air outlet 101. When it passes through the converging port 5, it is blown out from the inside of the filter element 3 to the outside, thereby blowing out the dust adhering to the surface of the filter element 3 and reducing the clogging. When outside air passes through the converging port 5, the filter screen 9 can filter out large particles in the air. Impurities are filtered out. After prolonged use, pull down the sliding plate 11 to disengage the insertion plate 1101 from the square slot in the fixed plate 901. This allows the filter screen 9 to be pulled out from the collection port 5 for easy cleaning, ensuring efficient airflow. After cleaning, pull down the sliding plate 11 again to insert the filter screen 9 into the collection port 5. Then, release the sliding plate 11. Under the return action of the return spring 1102, the insertion plate 1101 will re-insert into the square slot in the fixed plate 901, thus fixing the filter screen 9 to the collection port 5.

[0035] Example 2:

[0036] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 8 As shown, it also includes an anti-scattering component, which is located inside the main body 1 of the purifier.

[0037] The anti-scattering component includes: a surrounding adhesive tape 12; the surrounding adhesive tape 12 has a U-shaped structure and is disposed inside the purifier body 1.

[0038] The anti-scattering component also includes: hook and loop fastener 1201 and hook and loop hook 13; three hook and loop fastener 1201 are provided, and the three hook and loop fastener 1201 are respectively fixedly connected to the left and right sides and the rear of the surrounding tape 12; three hook and loop hook 13 are provided, and the three hook and loop hook 13 are dispersedly fixedly connected inside the purifier body 1.

[0039] The specific usage and function of this embodiment: The surrounding adhesive tape 12 is a pressure-sensitive adhesive coated cloth material. During the purification process of the filter element 3, the impurities adsorbed on the surface are blown to all sides. Some of them are discharged through the air inlet cover 2, and the other part is blown by the wind to the surrounding adhesive tape 12. Most of the impurities can adhere to the surface of the surrounding adhesive tape 12, avoiding too many impurities flying in the air, which would cause these impurities to be adsorbed by the filter element 3 again during subsequent air purification. At the same time, the surrounding adhesive tape 12 is fixed inside the purifier body 1 by the Velcro velvet side 1201 and the Velcro hook side 13, which makes it convenient to disassemble, clean or replace.
