Description

Technical Field

[0001] This utility model belongs to the field of gas filtration technology, and more specifically, it relates to an air particle filtration device. Background Technology

[0002] Air purifiers are household appliances that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to effectively improve air cleanliness. They are mainly divided into household, commercial, industrial, and building air purifiers. The filter of an air purifier is the core of the air purifier.

[0003] Patent CN202023049610.0, entitled "An Air Purifier with Convenient Filter Replacement," discloses an air purifier that facilitates filter replacement. The air purifier body includes a filter mounting bracket and a filter element. The filter element comprises a filter holder and a filter screen. Wedge-shaped blocks are provided on both sides of the filter mounting bracket, and a first spring is connected to each wedge-shaped block to press it against the sides of the filter holder. A holding part is provided at the tail end of each wedge-shaped block. The inner walls of the guide grooves on both sides of the filter mounting bracket have slots. A pressure block is provided at the bottom of the filter mounting bracket, and a second spring is connected to each pressure block to press it against the outside of the filter mounting bracket. The filter mounting bracket is processed separately and then assembled into the air purifier body, facilitating initial processing and subsequent maintenance. The disassembly slot allows the operator to easily push the holding part, and the second spring, in conjunction with the pressure block, facilitates the ejection of the filter holder. The operation is convenient, saving time and effort.

[0004] Patent CN202021789209.8, entitled "An Air Purifier with Quickly Replaceable Filters," discloses an air purifier with quickly replaceable filters. It includes a purification chamber, a battery compartment, a filter storage box, and multiple filters. The battery compartment is fixed to the top of the purification chamber. Air outlets and inlets are respectively located on the left and right side walls of the purification chamber. A fan is installed to the right of the air outlet, and an air quality sensor is located above the fan. Multiple partitions are provided at the bottom of the purification chamber, dividing it into a water storage compartment and a motor compartment. The water storage compartment is located below the fan. Multiple filters improve air filtration. The filter storage box allows for pre-storing of replacement filters. An automatic door and conveyor rollers enable quick filter replacement simply by operating the control panel, making operation more convenient and faster. A displacement sensor and a speed reducer ensure accurate filter placement by the conveyor rollers.

[0005] While the aforementioned patent documents have all solved the filter replacement problem, two issues still exist in air purification:

[0006] 1. In addition to removing dust, air purifiers can also remove odors and harmful gases. However, these purifiers need to have their filters replaced every once in a while, otherwise their purification effect will be greatly reduced. In addition, if the filters are not properly cleaned, they may cause secondary pollution.

[0007] 2. These are all large-scale air purification systems, which are expensive to build and maintain. In addition, they require enclosed buildings, which is inconsistent with our tradition of opening windows for ventilation when the air is good. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide an air particulate filtration device that addresses the problems of easy consumption, high cost, and inconvenient maintenance of current air purification filters.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] An air particle filtering device includes a fan, a filter screen, and a mounting bracket. The mounting bracket includes a first chamber and a second chamber. The top and bottom of the second chamber are respectively provided with corresponding upper and lower insertion ports. The fan is disposed in the first chamber, and the filter screen is disposed in the second chamber. Both ends of the filter screen are engaged with the upper and lower insertion ports. The side of the filter screen near the fan is provided with louvers.

[0011] The second chamber of the mounting frame is equipped with a water inlet and a drain outlet at the top and bottom, respectively. The second chamber of the mounting frame is also equipped with a mounting rod. The bottom of the outer wall of the second chamber of the mounting frame is equipped with a valve. Multiple nozzles are evenly distributed on the mounting rod. The bottom of the mounting rod is connected to the valve through a pipe.

[0012] This utility model discloses an air particle filtering device, wherein the filter screen is provided with a first support grid and a second support grid on both sides.

[0013] This utility model discloses an air particle filtering device, wherein the valve is also connected to the lower inlet via a pipe.
