Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a self-vibrating dust-removing air filter. Background Art

[0002] Air filters play a vital role in air filtration in various precision operating rooms, such as automobiles, motorcycles, and laboratories. Before starting, the engine draws in large quantities of air to fuel internal combustion. If this air is unfiltered, dust and impurities can be drawn into the cylinders. This not only forms carbon deposits on the intake valves but also enters the combustion chamber with the fuel-air mixture, resulting in incomplete combustion. This accelerates wear on the piston and cylinder walls and can cause severe "cylinder scuffing," making air filters an essential component of automotive engine mechanisms.

[0003] However, after long-term use, the filter element in the air filter will accumulate a lot of dust, thus losing its filtering function. Currently, the method of handling air filters is usually to manually remove and replace the internal filter element to reduce the processing load of the air filter. However, frequent replacement of new filter elements not only increases the maintenance cost of the air filter, but also affects the normal operation of the vehicle engine. Utility Model Content

[0029] Example 1

[0030] like Figure 1-2As shown, a self-vibrating dust removal air filter includes an air filter housing 1, a filter element 2, an air filter lower cover 3, a vibration dust removal generator 4, and an air outlet 7;

[0031] The filter element 2 is arranged inside the air filter housing 1 and connected to the inner wall of the air filter housing 1. The vibration dust removal generator 4 is arranged inside the air filter lower cover 3. The vibration dust removal generator 4 is used to shake off the dust particles on the filter element 2;

[0032] The air filter housing 1 is provided at one end of the air outlet 7, and the air outlet 7 extends into the interior of the filter element 2. A sealing ring 9 is fixedly installed at the end of the air filter housing 1. The sealing ring 9 is used to seal between the outside of one end of the air outlet 7 and the air filter housing 1. The other end of the air filter housing 1 is detachably fixedly connected to the air filter lower cover 3.

[0033] In this embodiment, the air filter also includes a controller 5 and a pressure sensor 6. The controller 5 is arranged in the air filter lower cover 3, and the pressure sensor 6 is arranged outside the air outlet 7. The vibration dust removal generator 4 and the pressure sensor 6 are electrically connected to the controller 5 respectively.

[0034] The controller 5 is a single chip microcomputer or a processor of x86 architecture, ARM architecture, or RISC-V architecture.

[0035] In this embodiment, the air filter housing 1 and the air filter lower cover 3 are both cylindrical structures, and the air filter housing 1 and the air filter lower cover 3 are connected by snap fasteners.

[0036] In this embodiment, the filter element 2 is a conical filter element. The size of the filter element 2 matches the size of the air filter housing 1. The upper bottom surface and the lower bottom surface of the filter element 2 are respectively adjacent to the upper end surface and the lower end surface of the air filter housing 1. The outer surface of the filter element 2 is covered with a layer of filter mesh.

[0037] The upper and lower ends of the filter element 2 are both provided with flanges 8, and the flanges 8 are made of rubber. The flange 8 at the upper end of the filter element 2 is in sealing contact with the outer wall of the air filter lower cover 3, and the flange 8 at the lower end of the filter element 2 is in sealing contact with the inner wall of the air filter housing 1, which effectively prevents the filter element from shaking under the action of airflow or vibration, and has a better fixing effect.

[0038] The bottom of the air filter housing 1 is provided with a dust exhaust air inlet 11 which is communicated with the inner cavity of the air filter housing 1 and is used for air intake or dust exhaust. The cross section of the dust exhaust air inlet 11 is a right triangle, and the dust exhaust air inlet 11 is provided on the outside of the filter element 2.

[0039] In this embodiment, two handles 10 are provided on the outer side of the air filter housing 1 , and anti-slip covers are provided on the handles 10 .

[0040] The air filter provided in this embodiment is similar in size and diameter to ordinary air filters, which increases the installation flexibility of the product.

[0041] Working principle: When the present invention is in use, air enters the interior of the air filter housing 1 through the dust exhaust inlet 11, and the dust particles in the air are deposited on the surface of the filter element 2. Clean gas enters the interior of the filter element 2 and is discharged from the air outlet 7. The controller 5 is electrically connected to the vibration dust removal generator 4 and the pressure sensor 6. The pressure sensor 6 detects the air pressure inside the air outlet 1 and transmits the detected air pressure value to the controller 5. The controller 5 compares the air pressure value with the preset air pressure value. When the air pressure value detected by the pressure sensor 6 exceeds the preset air pressure value, the controller 5 controls the vibration dust removal generator 4 to make noise after the vehicle stops. At this time, the filter element 2 will resonate, thereby shaking off the dust particles attached to the surface of the filter element 2 and discharging them from the dust exhaust inlet 11 at the bottom of the air filter housing 1, completing a backflush process. When the air pressure value detected by the pressure sensor 6 does not exceed the preset air pressure value, the vehicle can continue to work. The control logic involved above is the commonly used control logic of those in this field and is not the innovation of this application.

[0042] The above description of the embodiments is intended to facilitate understanding and use of the present invention by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the present invention is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this invention without departing from the scope of this invention should be considered within the scope of protection of this invention.
