Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an anti-allergy air filter. Background Technology

[0002] With the acceleration of industrialization, a large amount of factory emissions and vehicle exhaust are released into the air, leading to an increase in the content of particulate matter and harmful gases in the air. These pollutants not only affect the freshness and odor of the air, but also pose a direct threat to human health, especially to people with more vulnerable respiratory systems. As people's living standards improve, they are paying more and more attention to health. People are gradually recognizing the close relationship between air quality and health and are beginning to actively seek various methods to improve indoor and outdoor air quality in order to reduce the harm of allergens and pollutants to the body and improve their quality of life and health.

[0003] A search revealed Chinese Patent Publication No. CN221601600U, which discloses an air filter. The key technical points are: it includes a body, a filter element, a water cup, and a drain nozzle. The water cup is mounted on the body and used to store dirt. The filter element is mounted on the body and housed within the water cup for filtering airflow. The drain nozzle is installed at the bottom of the water cup and includes a drain component and a piston assembly. The drain component has a water channel, and the piston assembly seals the end of the water channel. The piston assembly does not need to be inserted into the water channel and abut against the inner wall of the water channel. The movement of the piston assembly is less affected by dirt corrosion, allowing for frequent drainage and pressure relief through the drain component, thus stabilizing the internal pressure of the air filter. However, this invention does not consider that simple filtration cannot remove most impurities from the air, resulting in air quality that does not meet requirements and failing to reduce allergic reactions in users. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-allergy air filter, which aims to improve the problem that the simple filtration in the prior art cannot filter out most of the impurities in the air, thus making the air unable to meet the required conditions and unable to reduce the user's allergy symptoms.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-allergy air filter, comprising a housing, an air outlet connected to the top left side of the housing, a filter screen fixedly connected to the right side of the inner wall of the housing, a rotating column rotatably connected to the front side of the housing, a guide plate fixedly connected to the middle of the outer wall of the rotating column, a filter plate fixedly connected to the right side of the middle of the inner wall of the housing, filter cotton fixedly connected to the middle of the inner wall of the housing, a motor fixedly connected to the left side of the inner wall of the housing, a fan fixedly connected to the output end of the motor, and a disassembly mechanism provided at the bottom of the housing for disassembling the filter device.

[0006] Through the above technical solution: the outer shell is connected to the air outlet, ensuring smooth airflow; the filter screen can filter out larger impurities; the rotating column makes equipment maintenance extremely convenient; the guide plate provides a precise path for airflow guidance; the filter plate further enhances filtration efficiency; the motor provides power for the entire equipment; the fan is responsible for delivering the purified air into the room; and the disassembly mechanism makes disassembling the filter equipment easy and efficient, which not only facilitates daily cleaning and maintenance but also extends the service life of the equipment.

[0007] As a further description of the above technical solution:

[0008] The disassembly mechanism includes a rotating shaft, the outer wall of which is rotatably connected to the bottom of the outer casing. A rotating plate is fixedly connected to the right side of the outer wall of the rotating shaft. A handle is fixedly connected to the bottom of the rotating plate. Screws are threadedly connected to the front and rear sides of the bottom of the rotating plate. A sealing strip one is fixedly connected to the top left side of the rotating plate, and a sealing strip two is fixedly connected to the top right side of the rotating plate.

[0009] The above technical solution ensures the flexibility and convenience of the device during operation by rotating the shaft and connecting them to the outer casing. The rotating plate enhances the stability of the structure, and the handle takes into account the user's comfort and grip during use, making the operation more user-friendly. The rotating plate is connected to the screw thread, ensuring a firm connection between the screw and the rotating plate, and also facilitating later maintenance and replacement. Sealing strip one and sealing strip two are used to ensure the sealing between the rotating plate and the outer casing during rotation, preventing the intrusion of dust or liquid, thereby protecting the normal operation of the internal mechanical structure.

[0010] As a further description of the above technical solution:

[0011] Support rods are fixedly connected to the bottom left and right sides of the outer casing, and anti-slip pads are fixedly connected to the bottom of the support rods.

[0012] The above technical solution ensures the stability and durability of the equipment. The support rod not only provides structural support but also is fixedly connected to the anti-slip pad, thus providing a stable grip on various surfaces and preventing the equipment from sliding.

[0013] As a further description of the above technical solution:

[0014] A dustproof net is fixedly connected to the top of the inner wall of the air outlet, and an identification plate is fixedly connected to the top of the outer shell.

[0015] Through the above technical solutions, the dustproof net provides double protection against dust re-entering the air, and the label provides necessary operating information, enabling users to understand and use the equipment more intuitively.

[0016] As a further description of the above technical solution:

[0017] A controller is fixedly connected to the rear side of the housing, and the controller is electrically connected to the motor.

[0018] Through the above technical solution: the controller ensures the stability of the structure, enabling the housing and the controller to be firmly connected, thus providing a reliable support foundation for the entire device. The controller is electrically connected to the motor, ensuring that the controller can effectively control the operation of the motor, enabling the motor to perform precise operations according to the controller's instructions.

[0019] As a further description of the above technical solution:

[0020] A knob is provided on the rear left side of the controller, and a display screen is fixedly connected to the rear right side of the controller.

[0021] Through the above technical solutions, the knob allows users to make precise manual adjustments, and the display screen can show the operating status of the device in real time, enabling users to understand the device information more intuitively and conveniently during operation.

[0022] As a further description of the above technical solution:

[0023] The outer wall of the handle is fixedly connected with an anti-slip sleeve, and the outer wall of the screw is provided with a washer.

[0024] Through the above technical solutions: the anti-slip sleeve ensures the user's grip safety even in wet and slippery environments, and the gasket not only reduces friction when the screw contacts the rotating plate, but also extends the screw's service life.

[0025] As a further description of the above technical solution:

[0026] The multiple support rods are fixedly connected to each other by connecting columns, and the outer walls of the rotating columns are threaded with limit rings on both the left and right sides.

[0027] Through the above technical solutions, the connecting column ensures the robustness and reliability of the overall structure, further enhancing the stability of the structure. The limiting ring not only increases the adjustment accuracy of the rotating column, but also effectively prevents excessive rotation that may occur during use, thereby protecting the equipment from damage.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when the motor is turned on, the fan rotates, the air pressure inside the outer casing decreases, and outside air is drawn in. The air first passes through the filter screen to remove large particulate impurities, then the guide plate guides the air flow, the filter screen further removes small particulate impurities, and finally the air is purified by the filter cotton. This achieves multiple filtration and purification of the air, reduces pollutants in the air, improves air quality, and thus prevents the occurrence of allergies.

[0030] 2. In this utility model, when disassembling the filter structure, the screws are unscrewed, causing the rotating plate to lose its support. Pulling the handle will cause the rotating plate to rotate around the shaft, and the filter plate and filter cotton will fall off. New filter plates and filter cotton can then be installed. The bottom of the outer shell is sealed with sealing strip one and sealing strip two, which realizes the disassembly and replacement of the filter equipment and prevents the accumulation of filtered impurities due to prolonged use, thereby reducing the filtration effect.

The display screen 15 can display the operating status of the equipment in real time, so that users can understand the equipment information more intuitively and conveniently during operation.

[0047] Working principle: When air filtration is required, motor 9 is started, which drives fan 10 to rotate. During the rotation of fan 10, the air pressure inside the outer casing 1 is reduced, causing the outside air to be pushed into the interior of the outer casing 1 by atmospheric pressure. When the air enters the outer casing 1, it first passes through filter screen 4, which filters out larger impurities in the air. Guide plate 6 provides the correct airflow direction. Filter plate 7 filters out smaller impurities in the air. Then it passes through filter cotton 8, which performs the final purification of the air. This achieves multiple filtration and purification of the air, reduces pollutants in the air, improves air quality, and thus prevents the occurrence of allergies.

[0048] When the filter structure needs to be disassembled, screw 204 is turned out from the bottom of the outer casing 1, and the rotating plate 202 loses its support. Pulling the handle 203 will cause the rotating plate 202 to rotate around the outer wall of the rotating shaft 201. After losing the support of the rotating plate 202, the filter plate 7 and filter cotton 8 will fall out from the inside of the outer casing 1, and then a new filter plate 7 and filter cotton 8 can be inserted. The sealing strip 1 205 and sealing strip 206 can seal the bottom of the outer casing 1, realizing the disassembly and replacement of the filter equipment, preventing the accumulation of filtered impurities due to prolonged use, thereby reducing the filtration effect.
