Description

Technical Field

[0001] This utility model relates to the field of automotive air filter dust removal technology, and in particular to an automotive air filter dust removal device. Background Technology

[0002] An automotive air filter, also known as an air filter cartridge, is primarily used for filtering the air in a car. During engine operation, a large amount of air is drawn in. If this air is not filtered, suspended dust particles will be sucked into the cylinders, accelerating wear on the piston assembly and cylinders. Larger particles entering between the piston and cylinder can cause severe "cylinder scoring." The automotive air filter is crucial for the engine; however, its numerous tiny pores make cleaning very difficult. Current methods involve using a brush and cleaning fluid. However, brushes struggle to penetrate the fine pores, especially in areas with interlayers, making cleaning impossible. Furthermore, the drying process after cleaning often leads to increased dust accumulation, making the process time-consuming, laborious, and ineffective. Utility Model Content

[0031] An automotive air filter, also known as an air filter cartridge, is primarily used for filtering the air in a car. During engine operation, a large amount of air is drawn in. If this air is not filtered, suspended dust particles will be sucked into the cylinders, accelerating wear on the piston assembly and cylinders. Larger particles entering between the piston and cylinder can cause severe "cylinder scoring." The automotive air filter is crucial for the engine; however, its numerous tiny pores make cleaning very difficult. Current methods involve using a brush and cleaning fluid. However, brushes struggle to penetrate the fine pores, especially in areas with interlayers, making cleaning impossible. Furthermore, the drying process after cleaning often leads to increased dust accumulation, making the process time-consuming, laborious, and ineffective.

[0032] Based on this, this application proposes a dust removal device for automotive air filters. The nozzle 220 provided in the extension 210 can remove dust from the automotive air filter placed on the support platform. It is simple to use, reduces the need for frequent replacement of automotive air filters, reduces maintenance costs, reduces the generation of waste filters, and reduces the impact on the environment.

[0033] The following is combined Figures 1-3 This invention describes a dust removal device for automotive air filters (hereinafter referred to as the device).

[0034] According to an embodiment of this application, a dust removal device for automotive air filters is proposed, including a support body 100 and a dust removal component 200. The support body 100 includes a support platform; the dust removal component 200 is connected to the support platform, and the automotive air filter can be placed on the support platform. The dust removal component 200 has an air chamber 201 inside, and the dust removal component 200 includes an extension 210 that extends out of the support platform. The dust removal component 200 is provided with a plurality of nozzle groups and an air inlet 202. The nozzle groups include a plurality of nozzles 220, which are distributed along the side wall of the extension 210. The nozzles 220 and the air inlet 202 communicate with the air chamber 201, and the air inlet 202 is adapted to connect to an external air pump.

[0035] The main support structure 100 is the foundational support structure of the entire device, providing a stable mounting and fixing position for other components. The support platform is used to place the automotive air filter element that needs dust removal. The support platform has a certain degree of flatness and stability to ensure that the air filter element can be placed stably on it without shaking or tipping over during the dust removal process.

[0036] The dust removal component 200 is the core part of the device that enables dust removal, and it is connected to the support platform. The dust removal component 200 has an internal air chamber 201, which is a closed cavity structure used to store and guide gas. The dust removal component 200 also includes an extension 210 that extends beyond the support platform. The extension 210 allows the nozzle 220 to get closer to the air filter element placed on the support platform, improving the dust removal effect.

[0037] Nozzles 220 are distributed along the side wall of the protrusion 210. This arrangement allows air to blow the car air filter placed on the support platform from multiple directions. The dust distribution on the air filter is often uneven, with different dust adhesion in different locations. Multi-directional airflow can more comprehensively cover the surface of the air filter, blowing away dust from every corner and greatly improving the thoroughness of dust removal.

[0038] The nozzle assembly includes multiple nozzles 220. The simultaneous operation of multiple nozzles 220 can increase the amount and range of gas ejection, forming a stronger airflow impact force, which can more effectively blow off the dust tightly attached to the air filter element, further enhancing the dust removal effect.

[0039] The car air filter can be placed on the support platform. This simple placement method allows operators to easily install the air filter onto the dust removal device without complicated installation steps and tools, reducing the difficulty of use and improving the convenience of operation.

[0040] The air inlet 202 is suitable for connecting to an external air pump, a common and readily available power source. Connecting an external air pump provides a stable air supply to the dust removal device, ensuring smooth operation. This design also enhances the applicability of the dust removal device, allowing for the selection of different air pump specifications based on actual needs.

[0041] In actual use, the operator simply places the car air filter that needs dust removal on the support platform and connects the external air pump to the air inlet 202. After starting the air pump, air enters the air chamber 201 through the air inlet 202 and is then ejected from each nozzle 220, forming a powerful airflow that blows away the air filter. After a period of dust removal, the dust on the air filter will be blown off, thus restoring some of its filtering capacity and extending the service life of the air filter.

[0042] Using this dust removal device can reduce the need for frequent replacement of car air filters. After a period of use, the air filter's filtering effect is affected by the accumulation of dust, usually requiring replacement. Regularly removing dust from the air filter using this device can restore some of its filtering capacity, extend its lifespan, and thus reduce the frequency and cost of filter replacement.

[0043] In some possible embodiments, the automotive air filter dust removal device can be placed vertically or horizontally. Vertical placement means the entire device is placed perpendicular to the ground, with the support platform and other structures forming approximately a 90-degree angle with the ground. Horizontal placement means the entire device is parallel to the ground, with the support platform and other structures extending horizontally.

[0044] When placed horizontally, the car air filter can be detachably connected to the support platform to achieve a fixed connection and ensure stability during the dust removal process.

[0045] According to one embodiment of this application, at least one set of nozzles is arranged along the extending direction of the dust removal component 200.

[0046] In this automotive air filter dust removal device, the nozzle assembly is a structural unit composed of multiple nozzles. Nozzle 220 is a key component for gas ejection. Through its specific shape and size design, it can eject the gas in the air chamber 201 at a certain pressure and speed, forming an airflow with a certain direction and intensity, which is used to blow away the automotive air filter placed on the support platform and remove the dust accumulated on the filter.

[0047] At least one set of nozzles is arranged along the extension direction of the dust removal component 200, meaning that nozzles 220 are distributed along the entire length or a specific extension path of the dust removal component 200. When gas is ejected from the nozzles 220, an airflow band is formed along the extension direction of the dust removal component 200, which thoroughly cleans the automotive air filter placed on the support platform. The air filter is impacted by the airflow in both its length and width directions, effectively removing dust from all parts of the filter and greatly improving the comprehensiveness of dust removal.

[0048] According to one embodiment of this application, the protrusion 210 has a circular structure, and the nozzle assembly is distributed circumferentially along the protrusion 210.

[0049] Because the protrusion 210 has a circular structure and the nozzle assembly is distributed circumferentially around it, when gas is ejected from the nozzle 220, the airflow can diffuse evenly in all directions from the center of the circular protrusion 210. This allows the airflow to cover all parts of the automotive air filter placed on the support platform, ensuring that both the central and edge areas of the filter are thoroughly cleaned by the airflow, thereby improving the uniformity and comprehensiveness of dust removal.

[0050] In one possible embodiment, the protrusion 210 is a polygonal structure with n sides, each side having at least one set of nozzles, where n≥3.

[0051] In this embodiment, the protrusion 210 is designed as a polygonal structure with n sides, where n ≥ 3. The polygonal structure has defined sides and angles, and its shape can be a regular polygon (such as an equilateral triangle, square, regular pentagon, etc.) or an irregular polygon.

[0052] The protruding portion 210 of the polygonal structure is composed of multiple side faces, each of which is a planar region. The number of side faces, n, determines the shape of the polygon; different values ​​of n correspond to different polygon shapes.

[0053] In this embodiment, each side is provided with at least one set of nozzles. The nozzles are used to spray the gas in the air chamber 201 at a certain pressure and speed to blow out the car air filter and remove the dust accumulated on the filter.

[0054] According to one embodiment of this application, when at least two sets of nozzles are arranged along the extension direction of the dust removal component 200, adjacent sets of nozzles are at least partially staggered along the extension direction of the protrusion 210.

[0055] It is understandable that adjacent sets of nozzles are staggered at least partially along the extension direction of the protrusion 210, meaning that adjacent sets of nozzles are not perfectly aligned in the extension direction of the protrusion 210, but rather there is a certain degree of misalignment. This misalignment can be partial or complete. This arrangement can change the direction and distribution of airflow, thereby improving the dust removal effect.

[0056] When two adjacent sets of nozzles are staggered at least partially along the extension direction of the protrusion 210, the airflow emitted by each set of nozzles will overlap and intersect to a certain extent in the extension direction of the protrusion 210. This overlap and intersect can expand the coverage of the airflow on the car air filter, allowing the airflow to act more comprehensively on all parts of the filter, reducing dust removal blind spots, and improving the uniformity and thoroughness of dust removal.

[0057] According to one embodiment of this application, the air inlet 202 is located at one end of the dust removal component 200 away from the protrusion 210.

[0058] Understandably, placing the air inlet 202 at the end of the dust removal component 200 away from the protrusion 210 allows for efficient use of the device's space. This provides a more convenient location for connecting an external air pump and also facilitates the arrangement of other internal structures within the dust removal component 200 (such as the air chamber 201, nozzle assembly, etc.).

[0059] According to one embodiment of this application, the spacing between adjacent nozzles 220 in the nozzle group is 50mm-200mm.

[0060] According to one embodiment of this application, the nozzle 220 is a flat nozzle 220. The flat nozzle 220 is a specific type of nozzle 220, characterized by its straight-outlet shape. When the airflow exits the nozzle 220, it forms a flat airflow jet. The flat nozzle 220 can cover a larger area of ​​the filter element surface under the same pressure and flow conditions. This allows each nozzle 220 to simultaneously clean a wider area of ​​the filter element during dust removal, improving dust removal efficiency and reducing the time required to complete the dust removal of the entire filter element.

[0061] According to one embodiment of this application, a fixing component 300 is included. The fixing component 300 is disposed at one end of the protrusion 210 away from the support platform. When the car air filter element passes through the protrusion 210, the fixing component 300 is used to fix the first end of the car air filter element, and the support platform is used to support the second end of the car air filter element.

[0062] The fixing component 300 is located at the end of the protrusion 210 away from the support platform. Working together with the support platform, it can effectively fix the car air filter on the device, ensuring that the filter will not shake or shift during the dust removal process, thereby ensuring the smooth progress of the dust removal operation.

[0063] The fixing component 300 can take various structural forms, such as clips or clamps. Its function is to firmly fix the first end of the automotive air filter element to the protrusion 210, preventing the filter element from moving during dust removal.

[0064] In one embodiment, the fixing component 300 is a fixing screw.

[0065] The installation and removal of the fixing screws are very simple, requiring only common tools such as wrenches and screwdrivers. When installing the car air filter, simply place the first end of the filter element in the corresponding position on the protrusion 210, and then tighten the fixing screws to secure the filter element. To remove the filter element, simply loosen the fixing screws to remove it from the device. This convenient installation and removal method improves operational efficiency and reduces maintenance time.

[0066] According to one embodiment of this application, the nozzle 220 is rotatably connected to the extension 210, and the spray angle of the nozzle 220 is adjustable by rotation.

[0067] By adjusting the spray angle of nozzle 220, the distribution of airflow on the filter element surface can be changed. For example, adjusting the spray angle of nozzle 220 to form a certain angle with the filter element surface can make the airflow form a more uniform coverage on the filter element surface, avoiding situations where the local airflow is too strong or too weak, thereby improving dust removal efficiency and quality.

[0068] The nozzle 220 can be oscillated by a controller.

[0069] It should be noted that the spray range of a traditional fixed nozzle 220 is limited, and it can only purge a local area of ​​the filter element. In contrast, the oscillating nozzle 220 can reciprocate within a certain angle range, allowing the airflow to cover a larger area of ​​the filter element.

[0070] Specifically, the oscillation of nozzle 220 is achieved through a drive mechanism, such as a motor or cylinder. The controller is the core component for controlling the oscillation of nozzle 220. It receives external input signals (such as buttons, touch screens, sensors, etc.) or preset programs, and sends control signals to the drive mechanism according to the set parameters to control the oscillation angle, speed, and direction of nozzle 220.

[0071] In one possible embodiment, the nozzle 220 is connected to the protrusion 210 via a spherical hinge.

[0072] The spherical hinge allows the nozzle 220 to swing in all directions in three-dimensional space, with a wide range of swing angles, which can adapt to the dust removal needs of automotive air filters of different shapes and sizes.

[0073] According to one embodiment of this application, a drive component is included. The dust removal component 200 is rotatably connected to the support platform, and the drive component is connected to the support platform. The drive component is adapted to drive the support platform to rotate relative to the dust removal component 200.

[0074] The dust removal component 200 can be rotatably connected to the support platform via a specific rotating connection structure. This rotating connection structure can employ common bearing connections, such as mounting holes on the support platform, with a matching bearing installed on the dust removal component 200, allowing the dust removal component 200 to rotate relative to the support platform around the bearing's central axis. This rotating connection method is simple in structure and flexible in rotation, ensuring smooth relative rotation between the dust removal component 200 and the support platform, reducing friction and resistance, and improving the stability and reliability of the device.

[0075] The drive component is fixedly connected to the support platform. The drive component can be a motor, which is mounted on the support platform using bolts or other fasteners. The motor has an output shaft, which can be connected to the support platform via gear transmission, belt transmission, or other means to drive the rotation of the support platform.

[0076] In some possible embodiments, the drive component employs a gear transmission, with a small gear mounted on the motor's output shaft and a large gear mounted on the support platform, the small and large gears meshing together. When the motor starts, the output shaft drives the small gear to rotate, which in turn drives the large gear to rotate, thereby achieving the rotation of the support platform relative to the dust removal component 200. This transmission method has advantages such as high transmission efficiency and accurate transmission ratio, enabling precise control of the rotation speed and direction of the support platform.

[0077] The drive unit is adapted to drive the support platform to rotate relative to the dust removal component 200. In actual operation, the car air filter is placed on the support platform, the drive unit is started, the drive unit drives the support platform to rotate, and thus the car air filter placed on the support platform also rotates, and then dust is removed through the nozzle 220.

[0078] Meanwhile, the rotation speed of the support platform can be controlled by adjusting the rotation speed of the drive components, thus adapting to the dust removal needs of different objects. For example, for objects with a lot of surface dust that is difficult to remove, the rotation speed of the support platform can be appropriately reduced.

[0079] In one embodiment, the support body 100 includes support legs, and a support platform is connected to the support legs for supporting the support platform.

[0080] The support legs are the key components where the support body 100 contacts the supporting surface (such as the ground). The support legs can be made of metal (such as steel) and are designed in a cylindrical shape. This shape provides good stability and load-bearing capacity, effectively distributing the weight of the support platform and the objects on it onto the ground. Additionally, anti-slip pads can be installed at the bottom of the support legs. These pads can be made of rubber with an uneven textured surface, increasing friction between the support legs and the ground, further improving the stability of the support and preventing slippage under external forces.

[0081] The support platform is connected to the support legs using a specific connection method. This connection can be achieved using bolts or welding.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
