Description

A dust removal filter Technical Field

This utility model relates to the field of air conditioning filtration technology, and in particular to a dust removal filter.

Background Technology

Air conditioner filters effectively filter out fine particulate matter such as dust, pollen, bacteria, viruses, and pet hair from the air, preventing these pollutants from entering indoor air. Improving indoor air quality: By filtering pollutants from the air, air conditioner filters help improve indoor air quality and reduce adverse effects on human health, especially for people with allergies or respiratory problems.

A search revealed Chinese Patent Publication No. CN207769379U, which discloses a membrane-coated activated carbon filter element, comprising an activated carbon filter element and a protective membrane. The activated carbon filter element has protective membranes at both its upper and lower ends, and the filter element and protective membranes are bonded together with adhesive. This membrane-coated activated carbon filter element, by covering the activated carbon filter element with an adhesive protective membrane, whose size can be customized according to the size of the activated carbon filter element, easily adheres to the surface of the activated carbon filter and is easy to peel off during use. This solves the problem of activated carbon powder falling off during transportation due to collisions and friction. The falling powder is directly adhered to the protective membrane on the surface, preventing it from falling into the packaging bag and contaminating the product's edges and packaging. It also solves the problem of oxidation caused by the adsorbent material inside the activated carbon filter element coming into contact with air, extending the shelf life of the activated carbon filter element and providing significant benefits. However, in actual use, the above-mentioned devices have problems. Traditional air conditioners only have a coarse filtration function, such as blocking hair and coarse dust particles. When installing multi-layer filters, they are not secure and the installation is relatively troublesome. Therefore, a dust removal filter is proposed to solve the above problems.

Utility Model Content

To overcome the above shortcomings, this utility model provides a dust removal filter, which aims to improve the problem that traditional air conditioners only have a coarse filtration function and that the installation of multi-layer filters is relatively troublesome.

To achieve the above objectives, the present invention adopts the following technical solution: a dust removal filter screen, comprising a shell, a cross plate fixedly connected inside the shell, screws fixedly connected to the four corners of the front side of the cross plate, an outer frame provided inside the shell, activated carbon honeycomb corrugated material fixedly connected inside the outer frame, multiple mounting holes provided on the front side of the outer frame, the outer walls of multiple screws disposed inside the mounting holes, the front ends of each screw penetrating the mounting holes and threadedly connected to a fixing cap, the front ends of multiple fixing caps fixedly connected to a soft rope, the other ends of multiple soft ropes rotatably connected to the front side of the shell, and an adjustment mechanism provided inside the shell.

The above technical solution involves aligning the mounting holes on the outer frame with the screws on the cross plate, and then fixing the outer frame with the fixing cap on the soft rope. The activated carbon honeycomb corrugated inside the outer frame can effectively filter and remove formaldehyde, acetaldehyde, and ammonia from the air conditioner, while minimizing air loss.

As a further description of the above technical solution:

The adjustment mechanism includes multiple air inlet plates, the left and right sides of which are fixedly connected to the inner side of the housing. A motor is fixedly connected to the bottom inner side of the housing. A threaded rod is fixedly connected to the output end of the motor. A connecting plate is threadedly connected to the outer wall of the threaded rod. A baffle plate is fixedly connected to the rear side of the connecting plate. The rear side of the baffle plate is located on the front side of the air inlet plates.

The above technical solution allows the start-up motor to adjust the air intake size of the air intake plate by driving the baffle. When the air conditioner is no longer running, the baffle can be closed to reduce dust from continuing to fall into the casing.

As a further description of the above technical solution: a limit block is fixedly connected to the top end of the threaded rod.

The above technical solution allows for significant restriction of the connecting plate on the threaded rod by using a limiting block, preventing it from falling off or becoming loose.

As a further description of the above technical solution: anti-slip strips are fixedly connected to the outer walls of the plurality of fixed covers.

The above technical solution allows for easy installation and use by fixing the anti-slip strips on the cover.

As a further description of the above technical solution: a filter plate is provided on the rear side of the activated carbon honeycomb corrugated sheet, and the bottom of the filter plate is fixedly connected to the bottom of the outer shell.

The above technical solution allows for the convenient filtration of large dust particles and hair in the air using a filter plate.

As a further description of the above technical solution: a controller is fixedly connected to the left side of the housing.

The above technical solution allows people to easily and conveniently operate and control the equipment on the entire device.

The above technical solution allows for convenient installation and fixation of the device using a fixing plate.

As a further description of the above technical solution: each of the multiple fixing plates has a screw hole on its front side, and each of the multiple screw holes is threaded with a bolt.

The above technical solution allows the device to be securely installed inside the air conditioner by using screw holes and bolts.

This utility model has the following beneficial effects:

1. In this utility model, activated carbon honeycomb corrugated board is installed and fixed by screw and fixing cover. Activated carbon honeycomb corrugated board has the effect of removing formaldehyde, acetaldehyde, acetic acid, ammonia and sulfur dioxide. At the same time, the formaldehyde removal rate is as high as 95% per hour. It can also be antibacterial and mildew-proof. Activated carbon honeycomb corrugated board has complete functions, is compatible with the cross-flow fan of air conditioner, does not have acid and odor phenomenon, and will not affect the energy consumption level of air conditioner.

2. In this utility model, the airflow can be adjusted at any time by means of a baffle plate. A threaded rod is fixed on the output end of the motor. The threaded rod drives the connecting plate on the baffle plate to move up and down, thereby controlling the size of the air inlet and greatly preventing dust from entering when the air conditioner is not in use.
