TECHNICAL FIELD

[0001] The present application relates to the technical field of air compressors, in particular to a filter cartridge applied to an air compressor. BACKGROUND

[0002] Air compressors are widely used in the fields of construction, industrial production, automobile manufacturing, etc. An air compressor needs to inhale a large amount of air during work. The inhaled air passes through the air inlet of the filter cartridge shell to the air filter position, and then the pure air enters the air compressor after being filtered by the air filter. After being compressed by the air compressor, the air drives the particulate material to flow into the tank.

[0003] During the process of inhaling air, impurities such as leaves and paper scraps in the surrounding air will enter the air compressor, thereby affecting the normal work of the air compressor. Therefore, a filter cartridge needs to be installed at the air inlet. In order to prevent the inhalation of leaves and other impurities, the existing filter cartridge assembly is usually provided with multiple baffles and blocking devices to prevent large impurities such as leaves and paper scraps from entering the inside of the filter cartridge, so as to avoid affecting the working efficiency of the air compressor. However, the blocking device can protect the air compressor from damage by impurities, but it also significantly reduces the air intake flow of the air compressor, thereby reducing the exhaust flow and working efficiency of the air compressor.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 the structural schematic diagram of the filter cartridge provided by the application applied to the air compressor is shown in the figure; Figure 2 the sectional view of the filter cartridge applied to the air compressor provided by some embodiments of the application is shown in the figure; Figure 3 the front view of the filter cartridge applied to the air compressor provided by some other embodiments of the application is shown in the figure.

[0034] The application provides a filter cartridge applied to an air compressor, which comprises an outer shell 1, a filter cartridge 2 and a bearing 3. The outer shell 1 is provided with a mounting cavity 11, the filter cartridge 2 is located in the mounting cavity 11 and used for filtering air entering the air compressor. The bearing 3 is arranged at the bottom of the mounting cavity 11, and at least one air inlet cavity 31 is formed in the bearing 3 and used for connecting the mounting cavity 11 with external air, so that the external air can enter the filter cartridge 2 in the mounting cavity 11 for filtering.

[0035] The outer shell 1 plays a whole supporting and protecting role, and is internally provided with the mounting cavity 11, and the filter cartridge 2 is mounted in the mounting cavity 11. The main function of the filter cartridge 2 is to filter air entering the air compressor and remove impurities, so as to ensure that the air entering the air compressor is pure, thereby ensuring the normal operation of the air compressor and avoiding damage caused by impurities and the like.

[0036] The bearing 3 is arranged at the bottom of the mounting cavity 11, and the air inlet cavity 31 can connect the mounting cavity 11 with external air, so that the external air can smoothly enter the filter cartridge 2 in the mounting cavity 11 for filtering. The bearing 3 is provided with at least one air inlet cavity 31, and each air inlet cavity 31 is connected with the mounting cavity 11 and external air, so that the external air can enter the filter cartridge 2 in the mounting cavity 11 for filtering.

[0037] In the embodiment of the application, the air inlet structure is optimized, the air is inhaled from the bottom of the outer shell 1, the air inlet cavities 31 of the bearing 3 combine the bottom outer shell 1, the air inlet cavities 31 can effectively increase the air inhalation amount while blocking the inhalation of impurities, and the working efficiency of the air compressor is improved. Therefore, the air inlet area and uniformity can be increased, the air inhalation amount is improved, and the working efficiency of the air compressor is improved.

[0038] In a specific embodiment, the air inlet cavities 31 are a plurality of air inlet cavities 31, and the plurality of air inlet cavities 31 are distributed along the circumferential direction and / or the radial direction of the bearing 3. The air inlet cavities 31 can be distributed along the circumferential direction of the bearing 3, can be distributed along the radial direction of the bearing 3, or can be radially arranged along the circumferential direction and the radial direction at the same time, so as to maximize the air inlet amount and the air inlet efficiency.

[0039] The support member 3 can be circular, which is convenient for actual manufacturing and installation, and also allows for better integration with other components of the air compressor. The specific structure of the intake chamber 31 includes a first intake wall 311 and a second intake wall 312 arranged opposite each other in the radial direction of the support member 3, and a third intake wall 313 and a fourth intake wall 314 arranged opposite each other in the circumferential direction of the support member 3. The first intake wall 311 is located outside the second intake wall 312, and the first intake wall 311 protrudes radially toward the edge of the support member 3, while the second intake wall 312 is recessed radially toward the first intake wall 311. The third intake wall 313 and the fourth intake wall 314 connect the first intake wall 311 and the second intake wall 312 respectively, and the four intake walls together enclose the intake chamber 31. This structure helps to enhance the structural strength and stability of the intake chamber 31, and also facilitates airflow and entry.

[0040] Optionally, the third intake wall 313 and the fourth intake wall 314 can also protrude in the circumferential direction and away from the intake cavity 31. This forms an outwardly expanding intake wall, which, combined with the aforementioned arc-shaped intake wall, forms a waist-shaped intake cavity. By designing the opening structure of the waist-shaped intake cavity and increasing the number of waist-shaped holes, for example, by distributing them radially along the support member 3, it can both block larger impurities from entering and increase the smoothness of air intake, increase the intake volume, and thus improve the exhaust flow and exhaust efficiency.

[0041] Optionally, the air intake chamber 31 has an arc length of L and a width of D, with the width-to-arc length ratio designed to be one-tenth to one-third. This size ratio ensures that the air intake chamber 31 has sufficient air intake area without being too large, which would affect the structural strength and compactness of the entire filter element 2. Multiple air intake chambers 31 can be evenly distributed along the circumferential and radial directions, allowing air to enter the filter element 2 uniformly for filtration, thereby improving the filtration effect and efficiency.

[0042] like Figure 4 As shown. Furthermore, the first air intake wall 311, the second air intake wall 312, the third air intake wall 313, and the fourth air intake wall 314 can extend from the bottom surface of the support member 3 along the direction close to the mounting cavity 11 into the interior of the mounting cavity 11, thereby forming an air intake channel directly connected to the mounting cavity 11. This reduces the resistance of air entering the filter element 2 and improves the smoothness of air intake.

[0043] In addition, a filter structure can be arranged on the air inlet channel, and the filter structure can be arranged on the cross section of the air inlet channel. The filter structure can be a static filter screen, filter cotton, or an active dust removal structure such as an air filter, a separator, a self-cleaning filter, a combined filter system, or the like. By arranging the filter structure on the cross section of the air inlet channel, the filter structure can be arranged at the bottom air inlet of the shell 1, and impurities, particulate matter, or pollutants in the air can be removed to achieve a pre-filtering effect.

[0044] In a specific embodiment, the filter structure includes an outer filter screen and a plurality of filter elements. The outer filter screen is arranged at the cross section of the air inlet of the air inlet channel, and the plurality of filter elements are arranged at the cross section of the air inlet channel inside the outer filter screen. The outer filter screen can filter out large-size or large-particle matter such as leaves, branches, stones, and construction workpieces, and the plurality of filter elements can filter out small-particle impurities such as sand, soil, dust, and the like, so as to ensure that the air entering the installation cavity 11 is air free of large-particle impurities, and to achieve pre-filtering of the air.

[0045] In summary, the filter cartridge provided by the present application effectively solves the problems of insufficient air intake, reduced air compressor discharge flow, and the like in the prior art. By increasing the number of air inlet cavities 31, optimizing the distribution mode and size ratio thereof, and combining the filter structure design, the present application can significantly improve the air intake and filtering effect, thereby improving the working efficiency and performance of the air compressor, reducing energy consumption, and saving use cost.

The principles and implementation modes of the present application are described by applying specific examples in this paper, and the above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that, for those skilled in the art, some improvements and modifications can be made to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
