Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a dual-outlet air duct structure for an air purifier. Background Technology

[0002] Air purification involves using a series of scientific and technological methods to treat the air, removing various pollutants and improving air quality. In modern society, with rapid industrialization and urbanization, as well as changes in people's lifestyles, air is polluted in many ways. Air may contain dust, pollen, bacteria, viruses, and harmful gases such as formaldehyde and benzene. These substances can have serious adverse effects on human health, causing various diseases, from mild respiratory discomfort to serious lung diseases and even cancer. The purpose of air purification is to create a cleaner and healthier air environment and protect people's health. This process typically employs various technologies such as physical filtration, chemical adsorption, electrostatic adsorption, photocatalysis, and negative ions. For example, physical filtration uses filters to intercept particulate matter in the air; chemical adsorption uses specific adsorbents to adsorb harmful gases; and electrostatic adsorption uses static electricity to remove particulate matter. Electric fields charge particles and cause them to be adsorbed. Through these different methods, various pollutants in the air can be effectively removed, allowing people to breathe cleaner, fresher air, improving quality of life and work efficiency. It also helps protect the environment and reduce the damage of air pollution to ecosystems. The filtration and cleaning mechanism enhances air purification, effectively intercepting various pollutants such as dust, pollen, and bacteria. It can be cleaned regularly to maintain high filtration efficiency and extend the lifespan of the air purifier. Furthermore, it can perform specific filtration for different pollutants, improving purification targeting. The cleaning mechanism makes the air purification process more sustainable, reducing the decrease in purification efficiency caused by filter clogging and other problems. This creates a healthier and more comfortable living and working environment, reduces health risks caused by air pollution, and improves quality of life. Therefore, a dual-outlet air duct structure for air purifiers is particularly needed.

[0003] However, the existing dual-outlet air duct structure of air purifiers has a relatively complicated filtration process, and cleaning after filtration is very troublesome, as is installation. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-outlet air duct structure for an air purifier, in order to solve the problems mentioned in the background art, such as the complex filtration process, the troublesome cleaning after filtration, and the complicated installation of the existing dual-outlet air duct structure for air purifiers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-outlet air duct structure for an air purifier, comprising a shell, a base, and vent holes. The base is mounted on the lower surface of the shell, vent holes are provided on the upper surface of the shell, a filter mechanism is provided on the inner surface of the shell, and mounting mechanisms are provided on both sides of the shell.

[0006] The filtration mechanism includes a placement ring, a locking block, a locking groove, a connecting cover, a placement block, a bolt, a filter screen, and an exhaust fan. A placement ring is installed on one side surface of the housing. A locking block is fixedly connected to the inner side surface of the placement ring. A locking groove is formed on one side surface of the locking block. A connecting cover is provided on one side surface of the placement ring. A placement block is fixedly connected to one side surface of the connecting cover. A bolt passes through one side surface of the placement block. A filter screen is provided on the inner side surface of the connecting cover.

[0007] Preferably, an exhaust fan is installed on the inner surface of the base.

[0008] Preferably, a filter screen is connected through one side surface of the vent hole.

[0009] Preferably, the inner locking block of the placement ring is connected to the connecting cover placement block by bolts.

[0010] Preferably, the inner wall dimensions of the slot match the outer wall dimensions of the placement block.

[0011] Preferably, the installation mechanism includes a connecting block, a fixing block, a placement hole, a placement sleeve, a semi-threaded rod, a retaining ball, and a rotary knob. The connecting block is installed on one side surface of the base, the fixing block is provided on the lower surface of the connecting block, the placement hole is formed through the upper surface of the connecting block, the placement sleeve is provided on the inner surface of the placement hole, the semi-threaded rod is provided on the inner surface of the placement sleeve, the retaining ball is provided on the outer surface of the semi-threaded rod, and a rotary knob is threadedly connected to the outer surface of the semi-threaded rod.

[0012] Preferably, the connecting block and the fixing block are provided with a placement hole.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: This air purifier features a dual-outlet duct structure. After installing the fixing block, the connecting block is placed on top, and then a placement sleeve is placed inside the connecting block. Next, the rotary knob is turned, causing the semi-threaded rod to rise. Simultaneously, the semi-threaded rod rises, causing the retaining ball to rise. The retaining ball presses against the connection between the connecting block and the fixing block, thus easily completing the base installation. This installation method is simple to operate, requiring no complex tools or professional installation skills, greatly improving installation efficiency. Both professionals and ordinary users can quickly complete the installation process, saving time and labor costs. Furthermore, this installation method facilitates later disassembly and maintenance. When cleaning, repairing, or replacing parts of the air purifier, the base can be easily disassembled for convenient operation. The exhaust fan plays a crucial role; after the exhaust fan is turned on, outside air is drawn into the vent and then into the filter for filtration. The filter effectively removes various pollutants from the air, such as dust, pollen, and bacteria, providing users with clean air. Moreover, when the filter is full, it can be easily emptied. Simply unscrew the bolt, rotate the connecting cover to allow the filter block to come out of the slot, and then open the connecting cover to remove the filter for cleaning. After cleaning, it can be reinstalled for continued use. This cleanable design extends the lifespan of the air purifier and reduces operating costs. Attached Figure Description

A placement ring 401 is mounted on one side surface of the outer casing 1. A locking block 402 is fixedly connected to the inner surface of the placement ring 401. A locking groove 403 is formed on one side surface of the locking block 402. A connecting cover 404 is provided on one side surface of the placement ring 401. A placement block 405 is fixedly connected to one side surface of the connecting cover 404. A bolt 406 passes through one side surface of the placement block 405. A filter screen 407 is provided on the inner surface of the connecting cover 404. The filtration mechanism 4, consisting of a placement ring 401, a locking block 402, a locking groove 403, a connecting cover 404, a placement block 405, a bolt 406, a filter screen 407, and an exhaust fan 408, allows for efficient airflow. The air fan 408 is designed to improve filtration. First, start the air extraction fan 408. Then, the air extraction fan 408 draws outside air into the vent 3. The air then enters the filter screen 407 through the vent 3 for filtration. After the air in the filter screen 407 is filtered, it is carried into the base 2 by the air extraction fan 408. When the filter screen 407 is full, unscrew the bolt 406 and rotate the connecting cover 404. The connecting cover 404 then moves the placement block 405 out of the slot 403. You can then open the connecting cover 404, remove the filter screen 407 for cleaning, and after cleaning, put the connecting cover 404 and the placement block 405 into the slot 402 and tighten the bolt 406 to continue use.

[0023] Furthermore, an exhaust fan 408 is installed on the inner surface of the base 2, and the exhaust fan 408 can be installed through the setting of the base 2.

[0024] Furthermore, a filter screen 407 is connected through one side surface of the vent 3, allowing air to be drawn in via the exhaust fan 408.

[0025] Furthermore, the inner locking block 402 of the placement ring 401 is connected to the placement block 405 of the connecting cover 404 and fixed by bolts 406. The filter screen 407 can be protected by the setting of the connecting cover 404.

[0026] Furthermore, the inner wall dimensions of the slot 403 match the outer wall dimensions of the placement block 405, allowing the placement block 405 to be placed.

[0027] Furthermore, the mounting mechanism 6 includes a connecting block 501, a fixing block 502, a placement hole 503, a placement sleeve 504, a semi-threaded rod 505, a retaining ball 506, and a rotary knob 507. The connecting block 501 is mounted on one side surface of the base 2. The fixing block 502 is located on the lower surface of the connecting block 501. The placement hole 503 is formed through the upper surface of the connecting block 501. The placement sleeve 504 is located on the inner surface of the placement hole 503. The semi-threaded rod 505 is located on the inner surface of the placement sleeve 504. The retaining ball 506 is located on the outer surface of the semi-threaded rod 505. The rotary knob 507 is threadedly connected to the outer surface of the semi-threaded rod 505. The mounting mechanism 6 is connected via the connecting block 501. The arrangement of the fixing block 502, placement hole 503, placement sleeve 504, semi-threaded rod 505, retaining ball 506, and rotary knob 507 improves the installation effect. First, install the fixing block 502, then place the connecting block 501 on it, and then place the placement sleeve 504 inside the connecting block 501. Then, turn the rotary knob 507. The rotary knob 507 will drive the semi-threaded rod 505 to rise. When the semi-threaded rod 505 rises, it will drive the retaining ball 506 to rise. When the retaining ball 506 rises, it can press against the connection between the connecting block 501 and the fixing block 502, and then the installation of the base 2 can be completed.

[0028] Furthermore, the connecting block 501 and the fixing block 502 are provided with a placement hole 503, which allows the placement sleeve 504 to be placed.

[0029] Working principle: First, install the fixing block 502, then place the connecting block 501 on top, and then place the placement sleeve 504 inside the connecting block 501. Next, turn the rotary knob 507, which will cause the semi-threaded rod 505 to rise. As the semi-threaded rod 505 rises, it will also cause the retaining ball 506 to rise. When the retaining ball 506 rises, it will press against the connection between the connecting block 501 and the fixing block 502, thus completing the installation of the base 2. Then, start the exhaust fan 408, which will draw outside air into the vent. Inside 3, air enters the filter screen 407 through the vent 3 for filtration. After the air in the filter screen 407 is filtered, it is drawn into the base 2 by the exhaust fan 408. When the filter screen 407 is full, unscrew the bolt 406 and rotate the connecting cover 404. Then, the connecting cover 404 drives the placement block 405 out of the slot 403. Then, the connecting cover 404 can be opened, and the filter screen 407 can be taken out for cleaning. After cleaning, the connecting cover 404 drives the placement block 405 into the slot 402 and the bolt 406 is tightened for continued use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
