Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to an air filter with easy-to-replace activated carbon. Background Art

[0002] An air filter is a device that captures dust from a gas-solid two-phase flow through a porous filter material, purifying the air. It purifies low-dust air before delivery to the indoor environment, ensuring the process requirements of clean rooms and the air cleanliness of typical air-conditioned rooms. The prototype of the air filter is a respiratory protection device used for respiratory protection. Significant advances have also been made in filter design, the most significant of which is the removal of partitions, resulting in the development of partitionless filters. Partitionless filters not only eliminate the risk of partitions damaging the filter medium but also effectively increase the filtration area, improve filter efficiency, and reduce airflow resistance, thereby reducing energy consumption. Furthermore, significant progress has been made in air filters' resistance to high temperatures, corrosion, water, and bacteria, meeting specialized requirements.

[0003] For example, an air filter that is easy to replace activated carbon, as disclosed in the authorization announcement number CN219424002U, includes a shell, universal wheels are fixedly installed at the four corners of the lower end of the shell, air outlets communicating with the interior of the shell are provided at the left and right ends of the shell, two air inlet slots and a No. 2 mounting slot are provided at the upper end of the shell, a filter body can be detachably installed in both of the air inlet slots, a protective body can be detachably installed in the No. 2 mounting slot, an exhaust fan is fixedly installed in the shell, and two positioning parts are fixedly welded at the front and rear ends of the shell. The air filter that is easy to replace activated carbon described in the utility model can complete the installation of the activated carbon filter by snapping the connecting pin into the connecting hole. It has a simple structure, eliminates the trouble of disassembly with the help of tools, saves time and effort, and fixes the protective body in the No. 2 mounting slot by snapping the positioning ear into the corresponding positioning slot, which is easy to disassemble and easy to clean and maintain. However, the air filter of this utility model is installed vertically, which is not convenient for installing and removing larger air filters. The filter needs to be lifted up, which is quite laborious. Therefore, we propose an air filter that is easy to replace activated carbon, which solves the installation and removal laborious problem of this utility model and improves the convenience and practical effect of this utility model.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This type of air filter that is easy to replace activated carbon, during installation, press the pressing handle provided by the limiting mechanism downward to move the limiting pin downward. When the activated carbon filter screen is pushed into place, release the pressing handle. At this time, the reset spring resets, driving the limiting pin to move upward and insert into the limiting hole, thereby achieving the effect of fixing the position of the activated carbon filter screen. In actual operation, the installation and disassembly method of this type of activated carbon filter screen is simple to operate.
