Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a direct-flow air filter which is convenient for replacing a filter screen. Background Art

[0002] An air filter is a device used to purify impurities and pollutants from the air. They are often used in indoor environments, such as homes, offices, factories, etc., to improve air quality and protect people's health. The working principle of an air filter is to remove harmful substances such as dust, pollen, bacteria, viruses, mold, smoke, odor, etc. from the air by inhaling air and passing it through a filtration system. It is used to capture larger particles such as dust and hair to protect more delicate filters from damage. High-efficiency particulate air (HEPA) filters are one of the most important components in air filters. It can effectively remove tiny particles in the air, such as bacteria, viruses, pollen, etc., and can usually filter out more than 99% of particles of 0.3 microns in size. Using an air filter can effectively improve indoor air quality and reduce the impact of allergens and harmful substances on the human body, especially for patients with respiratory diseases such as asthma and allergies, and people who are in a highly polluted environment for a long time. It is of great significance.

[0003] Air filters are an indispensable tool in modern development that can help improve air quality. The existing direct current air filters are generally fixed in the air filters during use, which is inconvenient to replace, resulting in the accumulation of thicker and thicker layers in the filters. Therefore, if they are not treated, bacteria produced by long-term use will repeatedly enter, thus affecting human health.

[0004] Therefore, it is urgent to provide a direct-flow air filter that is convenient for filter replacement to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the disadvantages of the prior art and provide a direct-flow air filter which is convenient for filter replacement.

[0007] A plurality of partitions are fixedly connected inside the main body, a winding box is fixedly connected to the front end of the main body, and a winding mechanism is installed inside the winding box.

[0008] The utility model is further configured as follows: a plurality of the partitions are fixedly connected to the front end of the main body, another plurality of the partitions are fixedly connected to the rear end of the main body, and the outer walls of the plurality of the partitions are slidably connected to the filter body.

[0009] Through the above technical solution, when in use, multiple partitions are fixedly connected to the inner wall of the main body, and then one end of multiple partitions is fixedly connected to the inner wall of the main body, and the other end is separated from the main body by a certain distance, and then another multiple partitions are connected to the other end of the inner wall of the main body. The rest is the same as the above method, and then the filter body is interspersed between the multiple partitions to prevent the filter body from being knotted inside the main body, thereby ensuring the basic functional effect of the filter body.

[0010] The utility model is further configured as follows: the fixing mechanism includes a buckle ring movably connected to the rear end of the filter body, the rear end of the buckle ring is fixedly connected to a threaded rod, the front end of the buckle ring is rotatably connected to an angular fixer, and the interior of the angular fixer is rotatably connected to the threaded rod.

[0011] Through the above technical solution, during use, when the filter body is replaced, the filter body is connected to the new filter through the fixing mechanism, ensuring that after the filter body is replaced, a new filter can be used to replace it, thereby ensuring the normal use effect of the air filter. Specifically, one end of the buckle is connected to the buckle on the filter body, and then the other end of the buckle is connected to the new filter, and then the angle fixer is rotated until the angle fixer can be rotated to a certain position after the threaded rod is rotated. The basic operation is completed, thereby ensuring the normal replacement of the filter.

[0012] The utility model is further configured as follows: the winding mechanism includes a motor fixedly connected to the top of the winding box, the output end of the motor is fixedly connected to a driving shaft, the outer wall of the driving shaft is provided with a filter connection, and the outer wall of the filter connection is fixedly connected to the filter body.

[0013] Through the above technical solution, when using, when replacing the filter, the winding mechanism can be used to roll up one end of the filter body until the filter body is completely pulled out of the main body, and a new filter can be brought in, so that the replacement of the filter is more convenient. Specifically, the motor on the top of the winding box is started to drive the drive shaft to rotate. Since the outer wall of the filter connection is fixedly connected to the filter body, the filter body can slide through the partition inside the main body, and in the case of multiple partitions, when the new and old filters are replaced and slid, the filter will not be confused, thereby ensuring the normal replacement.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model has a simple fixing mechanism and a winding mechanism, and can realize the movement and replacement of the filter inside the main body according to the flow of the filter itself when the DC air filter is used, so that the filter can be replaced quickly without other operations, thereby greatly improving the convenience of filter replacement;

[0016] 2. The utility model has a simple winding mechanism and can be driven by a motor at the rear of the air filter, so that the filter can be dragged and retracted at the rear, and the filter can be replaced and connected at the front, so that the used filter can be pulled out and replaced with a new filter at the same time, thereby greatly improving work efficiency.
