Description

Technical Field

[0001] This utility model belongs to the field of air intake systems, specifically relating to an air filter and a motorcycle. Background Technology

[0002] An air filter (also known as an air cleaner or air filter) is an important component of the intake system of vehicles such as cars, ATVs, and motorcycles. Its main function is to filter out impurities and dust from the air, allowing clean air to enter the engine cylinders and protecting the engine from wear and damage. Air filters typically use a filter element installed inside a housing to filter the intake air, then provide the relatively clean air to the engine. Furthermore, the design of the air filter directly affects the engine's intake efficiency and power performance. Therefore, the performance and condition of the air filter are crucial to the overall performance of the vehicle and driving safety.

[0003] Existing air filters, especially those used on scooters, are generally located above the engine and below the storage box, making them visible. Their overall height is not high. During prolonged use, the filter element inside the air filter needs to be replaced in time once its filtration capacity reaches saturation. However, since the filter element is usually encased inside the casing, it is difficult to observe directly from the outside. Users cannot understand the condition of the filter element in a timely manner, which can easily lead to poor filtration due to failure to replace the filter element in time. Summary of the Invention

[0025] <Example>

[0026] This embodiment proposes an air filter that can be applied to automobiles or motorcycles, especially motorcycles. Motorcycles typically include a frame, engine, air filter, and instrument panel. The air filter is generally connected to the engine via a pipe and is arranged together in the middle of the frame. The instrument panel is mounted at the head of the frame, between the two handlebars, for easy observation by the user while riding. This air filter 10 is an intelligent air filter. The air filter and the instrument panel are connected via communication, and the instrument panel can display relevant data and usage status of the air filter, allowing the user to observe the current status of the air filter in a timely manner, providing timely maintenance reminders, and preventing engine damage due to user negligence.

[0027] Specifically, such as Figures 2-5As shown, the air filter 10 includes an air outlet box 30, an air inlet box 40, and a filter assembly 50. The air outlet box 30 has an air outlet chamber 31 and is equipped with a clean air outlet pipe 32. The air inlet box 40 is installed on the air outlet box 30, has an air inlet chamber 41, and is equipped with a dirty air inlet pipe 42. The filter assembly 50 is installed between the air inlet box 30 and the air outlet box 40 to filter the dirty air from the dirty air inlet pipe 42. The filtered clean air enters the air outlet chamber 31 and finally exits from the clean air outlet pipe 32. The air outlet pipe 32 has an internal part 321 that extends into the air outlet chamber and an external part 322 that is exposed in the air outlet box 30. The opening end of the internal part 321 extends toward the filter assembly 50. A data acquisition device 61 is installed on the external part 322. The tube body of the external part 322 protrudes outward to form an installation tube 3221. The data acquisition device 61 is a micro-pressure sensor, which is fixed to the installation tube 3221 by fasteners and glue.

[0028] The filter assembly 50 includes a filter element 51 and a mounting bracket 52. The mounting bracket 52 is used to install the filter element 51 between the outlet box 30 and the inlet box 40. The outlet box 30 and the inlet box 40 each have an opening of a matching shape at their opposite ends. The mounting bracket 52 has a shape that matches the opening. The openings of both the outlet box 30 and the inlet box 40 are recessed inward to form fixing grooves 301 and 401. Figure 4 As shown, the mounting bracket 52 has a fixing body 521 and a mounting hole 522 opened in the middle of the fixing body 521. The two sides of the edge of the fixing body 521 protrude outward to form fixing protrusions 523. The fixing protrusions 523 on both sides are respectively embedded in two fixing grooves 301 and 401. The air outlet box 30 and the air inlet box 40 are then fixed together by screws, thereby fixing the air outlet box 30, the mounting bracket 52 and the air inlet box 40 together. In order to enhance the sealing of the connection structure, a sealing ring can also be added when the fixing protrusions 523 are engaged with the two fixing grooves 301 and 401.

[0029] like Figure 3 As shown, to enhance the stability of the mounting bracket 52, a limiting piece 524 protrudes outward from the outer edge of the fixing body 521, and a limiting hole 302 for inserting the limiting piece 524 is correspondingly formed on the air outlet box 30 or the air inlet box 40. In this embodiment, the limiting hole 302 is provided on the air outlet box 30. During installation, the limiting piece 524 is first inserted into the limiting hole 302, and then the fixing protrusion 523 is embedded into the fixing groove 301 to complete the installation between the mounting bracket 52 and the air outlet box 30. Finally, the air inlet box 40 is covered along the fixing protrusion 523.

[0030] With the mounting bracket 52 as the boundary, an air outlet chamber 31 is formed between one side of the mounting bracket 52 and the air outlet box 30, and an air inlet chamber 41 is formed between the other side of the mounting bracket 52 and the air inlet box 40. The mounting hole 522 in the middle of the mounting bracket 52 connects the air inlet chamber 41 and the air outlet chamber 31. The filter assembly 50 is installed on the mounting hole 522 so that the dirty gas in the air inlet chamber 41 can be filtered before entering the air outlet chamber 31.

[0031] like Figure 5 As shown, the filter element 51 includes a fixing plate 511, a filter screen 512, and filter paper 513. The fixing plate 511 is fixed to the side of the mounting bracket 52 facing the air outlet chamber. The filter screen 512 covers the side of the fixing plate away from the air outlet chamber. The filter paper 513 is installed in the mounting hole 522 of the mounting bracket 52 and is located on the side of the filter screen 512 facing the air inlet chamber. The filter screen 512 has several longitudinally and transversely arranged filter holes. The edge of the filter screen 512 is folded towards the side where the air outlet chamber is located to form an edging 5121 that wraps around the outer periphery of the fixing plate. Figure 4 As shown, two pairs of symmetrically arranged locking blocks 5221 are formed on the inner peripheral wall of the mounting hole 522 of the mounting bracket 52. A V-shaped groove is opened in the middle of the locking block 5221, and the filter paper 513 is inserted into the V-shaped groove for installation, making installation and disassembly very convenient. The fixing plate 511 and the filter screen 512 are placed on the back side of the filter paper 513 to support the filter paper 513.

[0032] The fixing body 521 has a mounting portion 525 formed on one side of the mounting hole 522 for mounting the dirty air intake pipe 42, such as... Figure 4 As shown, the mounting part 525 spans the fixed body 521 and is generally in the shape of a recessed groove facing the side where the air outlet 31 is located. A limiting protrusion 5251 protruding towards the side where the air inlet 41 is located is provided in the middle of the groove. A fixing part 43 is formed on the inner wall of the air inlet box 40 corresponding to the mounting part 525. The shape and structure of the fixing part 43 are basically the same as those of the mounting part 525. It is generally in the shape of a recessed groove facing the inner wall of the air inlet box 40. A limiting protrusion 431 protruding towards the side where the mounting part 525 is located is provided in the middle of the groove. A partition part 421 is integrally or separately provided on the dirty air inlet pipe 42 (in this embodiment, it is integrally provided). The two sides of the partition part 421 are respectively inserted into the fixing part 43 and the mounting part 525. A limiting slot for the limiting protrusions 5251 and 431 to be inserted is provided on the edge of the partition part 421.

[0033] like Figure 5As shown, the air intake chamber 41 is divided by the partition 421 to form an outer air intake chamber 411 and an inner air intake chamber 412. The dirty air intake pipe 42 has an outer dirty pipe portion 422 extending into the outer air intake chamber 411 and an inner dirty pipe portion 423 extending into the inner air intake chamber 412. The air intake box 40 is provided with a main air intake port 44. The end of the outer dirty pipe portion 422 away from the inner dirty pipe portion 423 is provided with a dirty air intake port 424, and the tail end of the inner dirty pipe portion 423 (i.e., the end away from the outer dirty pipe portion 422) is provided with a dirty air outlet 425. The air intake box 40 is also provided with a drain port 45 leading to the outside at the inner air intake chamber 422 for discharging larger dust impurities and wastewater that have been filtered out.

[0034] like Figure 2 As shown, taking the plane where the connection surface of the air inlet box 40 and the air outlet box 30 is located (i.e., the plane where the opening end of the air inlet box 40 or the air outlet box 30 is located) as the reference plane, the mounting holes 522 of the mounting bracket 52 are arranged at an angle, that is, the filter element 51 installed in the mounting holes 522 is arranged at an angle, and has a low point 51a and a high point 51b. The height of the high point 51b is higher than that of the low point 51a. The dirty air intake pipe 42 is also arranged at an angle, and the angle direction is the same as that of the filter element 51. With the same direction (i.e., on the reference plane, the height of the dirty gas outlet 425 is higher than the height of the dirty gas inlet 424), the length of the inner tube portion 423 is almost equal to or even greater than half the length of the filter element. In other words, the dirty gas outlet 425 is closer to the high point 51b of the filter element, allowing the dirty gas to enter from the high point 51b first when it is ready to be filtered, and then gradually penetrate to the low point 51a of the filter element, so that the gas can be filtered more thoroughly and the filtration effect is improved. The clean gas outlet 32 ​​inside the air box 30 has a clean gas inlet 3211 formed on the end of the inner part 321 away from the exposed part 322. The clean gas inlet 3211 is oriented towards and close to the low point 51a of the filter element, so that the gas filtered by the filter element can enter the clean gas outlet 32 ​​through the clean gas inlet 3211, and then be discharged into the engine through the clean gas outlet 32.

[0035] When the air filter is working, it draws in dirty air from the outside through the main air intake 44 by generating negative pressure for filtration. A data acquisition unit 61 is installed on the exposed part 322 of the clean air outlet pipe 32, which can collect relevant data when the air filter is working, such as the negative pressure value. Then, the data acquisition unit 61 converts the negative pressure value into a relevant voltage signal and sends it to the instrument, so that the instrument display shows relevant information about the air filter. This allows the user to observe the current status of the air filter in a timely manner, so that the user can maintain it in time and avoid engine damage caused by the user's negligence.

[0036] Technical effects of the example:

[0037] The air filter and motorcycle in the above embodiments have a data acquisition device installed on the clean air outlet pipe, which can collect data in the clean air outlet pipe and convert it into a signal to be sent to the instrument. This allows the air filter-related information to be displayed on the instrument in real time, providing users with timely maintenance reminders and preventing engine damage due to user negligence.

[0038] The above embodiments are preferred examples of this utility model and are not intended to limit the scope of protection of this utility model. Any simple modifications, equivalent changes or alterations made to the above embodiments based on the technical principles of this utility model shall still fall within the scope of the technical solution of this utility model.
