Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air purification, in particular to an external filtering type plastic sintered pleated filter cartridge. Background Art
[0002] The plastic fired pleated filter cartridge is a commonly used air filter, which is mainly used to filter dust and particulate matter. After the filter cartridge is installed in the air purifier, air enters the inside of the filter cartridge from the outside, while the dust and particulate matter are intercepted by the filter cartridge and remain in the air purifier. The filtered air is discharged through the air outlet to complete the air filtration. The present scheme specifically relates to an external filter type plastic fired pleated filter cartridge. When the existing external filter type plastic fired pleated filter cartridge is used for air filtering, it is impossible to automatically clean the dust attached to the outside of the filter paper cartridge. When dust accumulates, it is easy to cause the external filter type plastic fired pleated filter cartridge to be blocked. At the same time, the filter paper cartridge cannot be replaced separately after it is damaged. The external filter type plastic fired pleated filter cartridge needs to be replaced as a whole, and the replacement cost is high. Utility Model Content

[0008] As a further solution of the utility model, the buckle passes through the top of the top cover, and the buckle is arranged in an inverted "L" shape, and the horizontal section of the buckle is located at the top of the top cover.
[0009] As a further solution of the utility model, the housing of the motor is fixedly connected to the bottom cover, and the cleaning brush strip is tangent to the outer surface of the filter paper cylinder.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The utility model provides a cleaning component, starts a motor to drive the bracket to rotate, and then drives the cleaning brush strip to move along the outer surface of the filter paper drum through the rotating bracket, so as to sweep the dust attached to the surface of the filter paper drum, and avoid the dust accumulation on the outer surface of the filter paper drum and cause the filter paper drum to be blocked. At the same time, a top sealing cover, a buckle, an air outlet pipe, an inner filter cartridge and a docking card are provided. After the buckle is rotated 180°, the top sealing cover is removed, and then the filter paper drum is pulled out for easy replacement. After the filter paper drum is sleeved on the outside of the inner filter cartridge, the top sealing cover is covered, the docking card is inserted into the top sealing cover, and the inner filter cartridge is inserted into the air outlet pipe. The buckle is then rotated 180° again to limit the top sealing cover and fix the filter paper drum, so that a damaged filter paper drum is easily replaced, and there is no need to replace the outer filter type plastic fired pleated filter cartridge as a whole, thereby saving replacement costs.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-Figure 5As shown, an external filter type plastic fired pleated filter cartridge comprises a bottom cover 1, an inner filter cartridge 7 is fixedly installed at the center of the top of the bottom cover 1, four docking cards 8 are fixedly installed on the outer ring of the inner filter cartridge 7 near the top, a buckle 4 is movably installed on the top of the docking card 8, a top cover 3 is provided on the top of the inner filter cartridge 7, an air outlet pipe 5 is fixedly installed through the top of the top cover 3, a filter paper cartridge 2 is provided on the outside of the inner filter cartridge 7, and a cleaning component 6 is installed at the bottom of the bottom cover 1.
[0020] The cleaning component 6 includes a motor 601, a bracket 602 is fixedly installed at the end of the output shaft of the motor 601, and cleaning brush strips 603 are fixedly installed on both sides of the top of the bracket 602. By setting the cleaning component 6, the outer surface of the filter paper tube 2 is cleaned to prevent the outer ring surface of the filter paper tube 2 from being blocked due to dust adhesion and accumulation.
[0021] The filter paper cartridge 2 is sleeved with the inner filter cartridge 7, the top end of the inner filter cartridge 7 is clamped with the bottom end of the air outlet pipe 5, and the docking card 8 is clamped with the top sealing cover 3. After removing the top sealing cover 3, the filter paper cartridge 2 is removed from the inner filter cartridge 7 to facilitate replacement of the filter paper cartridge 2.
[0022] The buckle 4 passes through the top of the top cover 3, and the buckle 4 is set in an inverted "L" shape. The horizontal section of the buckle 4 is located at the top of the top cover 3. After the buckle 4 is rotated 180°, it is convenient to remove the top cover 3 from the top of the inner filter cartridge 7.
[0023] The housing of the motor 601 is fixedly connected to the bottom cover 1, and the cleaning brush strip 603 is tangent to the outer surface of the filter paper tube 2. After the motor 601 is started, it drives the bracket 602 to rotate, and then drives the cleaning brush strip 603 to slide on the surface of the filter paper tube 2 through the bracket 602, so as to clean the dust attached to the surface of the filter paper tube 2.
[0024] It should be noted that the utility model is an external filter type plastic fired pleated filter cartridge, which uses a bottom cover 1, a top cover 3 and an inner filter cartridge 7 to fix the filter paper cartridge 2. When in use, the air passes through the filter paper cartridge 2 and the inner filter cartridge 7 and enters the inner filter cartridge 7. The filter paper cartridge 2 is supported by the inner filter cartridge 7, and the filter paper cartridge 2 is used to filter the air.
[0025] During the filtering process, dust in the air is intercepted by the filter paper cylinder 2 and attached to the surface of the filter paper cylinder 2. The filtered air is discharged from the inside of the external filter type plastic sintered pleated filter cylinder through the air outlet pipe 5. The motor 601 in the cleaning component 6 is started, and the bracket 602 is driven to rotate by the motor 601, and then the cleaning brush strip 603 is driven to move along the outer surface of the filter paper cylinder 2 by the rotating bracket 602. The dust attached to the outer surface of the filter paper cylinder 2 is cleaned by the cleaning brush strip 603 to prevent dust accumulation from clogging the filter paper cylinder 2.
[0026] When the filter paper tube 2 is damaged, the buckle 4 is rotated 180°, and then the top cover 3 is removed to facilitate the extraction of the filter paper tube 2 and the replacement of the damaged filter paper tube 2. After the new filter paper tube 2 is put on the outside of the inner filter tube 7, the top cover 3 is covered on the top of the inner filter tube 7, so that the docking card 8 is engaged with the top cover 3, and the inner filter tube 7 is engaged with the air outlet pipe 5, so as to facilitate the fixation of the filter paper tube 2.
[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
