Description

Technical Field

[0001] This utility model relates to the field of automotive filter technology, specifically to an adjustable wind resistance filter. Background Technology

[0002] Automotive filters are the core components of automotive filtration systems. They primarily use fibrous materials to intercept and remove impurities from various media, thereby protecting the engine and the in-vehicle environment. The air resistance of the filter directly affects the system's energy consumption. The greater the air resistance, the stronger the power required for air to pass through the filter, and the more energy the air pump or fan needs to consume to maintain airflow. Appropriate air resistance can optimize airflow distribution and improve filtration efficiency.

[0003] Traditional automotive filters mostly adjust the air resistance of the filter by controlling the opening and closing of the air inlet at the filter element through a valve. However, this method has some drawbacks. For example, when adjusting the opening and closing of the air inlet at the filter element, dust will accumulate in the space between the inner and outer air inlets. Although a sealing ring is traditionally installed between the inner and outer air inlets to seal against dust, the sealing ring is easily worn due to friction during the adjustment of the inner and outer air inlets. This not only affects the dustproof effect of the sealing ring, but also makes the sealing ring itself prone to damage. Therefore, a filter element with adjustable air resistance is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable air resistance filter element that not only ensures the dustproof effect between the outer shell and the inner shell by filling the air bladder, but also reduces the contact friction on the filling air bladder during the adjustment of the opening and closing degree between the outer shell and the inner shell. Thus, it not only ensures the dustproof effect of the filling air bladder, but also makes the filling air bladder itself less prone to damage, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable air resistance filter element includes an outer shell, an inner shell, and a filter element body. A filling air bladder is provided between the outer shell and the inner shell. The outer shell has several first through holes arranged at equal intervals. The filling air bladder has several second through holes arranged at equal intervals. The inner shell has several third through holes arranged at equal intervals. An adjustment assembly is provided between the outer shell and the inner shell. A pneumatic assembly is provided above the filling air bladder. The adjustment assembly includes a drive motor, the output end of which is fixedly connected to a drive gear. A mounting ring groove is provided on the top outer side of the inner shell, and a drive gear ring is fixedly connected in the mounting ring groove. The pneumatic assembly includes a small air pump and a pneumatic through hole. The pneumatic through hole is located on the top of the filling air bladder and communicates with the pneumatic through hole. A solenoid valve is provided between the small air pump and the pneumatic through hole. The inner shell is located inside the outer shell, and the filter element body is located inside the inner shell. The inner side of the filling air bladder is fixedly connected to the outer side of the inner shell.

[0007] As a further optimization of this utility model, the first through hole, the second through hole, and the third through hole are set in equal numbers, corresponding positions, and matching specifications.

[0008] As a further optimization of this utility model, the top of the drive motor is fixedly connected to a first support plate, and the top of the first support plate is not higher than the top height of the outer casing.

[0009] As a further optimization of this utility model, one end of the first support plate is fixedly connected to the top of the inner wall of the outer shell, and the other end of the first support plate does not contact the inner shell.

[0010] As a further optimization of this utility model, the drive gear and the drive gear ring are at the same height, and the drive gear and the drive gear ring are meshed with each other.

[0011] As a further optimization of this utility model, a second support plate is fixedly connected to the top of the outer side of the small air pump, and the top of the second support plate is not higher than the top height of the outer casing.

[0012] As a further optimization of this utility model, one end of the second support plate is fixedly connected to the top outer side of the inner shell, and the other end of the second support plate is slidably connected to the top inner side of the outer shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the first, second, and third through holes provide pathways for air to pass through, allowing outside air to pass through the outer shell, the filling air bladder, and the inner shell, and finally be filtered by the filter element body. An adjustment component drives the inner shell and the filling air bladder to rotate, causing the first through hole on the outer shell to overlap or stagger to varying degrees with the second through hole on the filling air bladder and the third through hole on the inner shell. This overlap or staggering adjusts the air intake volume, thereby regulating the wind resistance of the filter element body. A pneumatic component inflates and deflates the filling air bladder, reducing or preventing contact and friction between the filling air bladder and the inner wall of the outer shell during inner shell rotation adjustment, preventing damage. Furthermore, after inner shell adjustment, a dustproof seal is filled between the inner and outer shells to ensure effective dust prevention. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] Please see Figure 1-7 This utility model provides a technical solution:

[0026] An adjustable air resistance filter element includes an outer shell 1, an inner shell 2, and a filter element body 3. A filling air bladder 4 is provided between the outer shell 1 and the inner shell 2. A plurality of first through holes 5 are arranged at equal intervals on the outer shell 1. A plurality of second through holes 6 are arranged at equal intervals on the filling air bladder 4. A plurality of third through holes 7 are arranged at equal intervals on the inner shell 2. An adjustment component 8 is provided between the outer shell 1 and the inner shell 2. A pneumatic component 9 is provided above the filling air bladder 4. The adjustment component 8 includes a drive motor 801, and a drive gear is fixedly connected to the output end of the drive motor 801. The inner housing 2 has a wheel 802. The outer top of the inner housing 2 is provided with a mounting ring groove 803. A drive gear ring 804 is fixedly connected in the mounting ring groove 803. The pneumatic assembly 9 includes a small air pump 901 and a pneumatic through hole 902. The pneumatic through hole 902 is opened at the top of the filling air bag 4. The small air pump 901 is connected to the pneumatic through hole 902. A solenoid valve 903 is provided between the small air pump 901 and the pneumatic through hole 902. The inner housing 2 is located inside the outer housing 1. The filter element body 3 is located inside the inner housing 2. The inner side of the filling air bag 4 is fixedly connected to the outer side of the inner housing 2.

[0027] As a further implementation of this solution, the first through hole 5, the second through hole 6, and the third through hole 7 are set in equal numbers, corresponding positions, and matching specifications. The first through hole 5, the second through hole 6, and the third through hole 7 can provide a passage path for air, allowing outside air to pass through the outer shell 1, the filling airbag 4, and the inner shell 2, and finally pass through the filter element body 3 for air filtration.

[0028] As a further implementation of this solution, a first support plate 805 is fixedly connected to the top of the drive motor 801. The top of the first support plate 805 is not higher than the top height of the outer casing 1. The first support plate 805 can provide fixed support for the drive motor 801, and this height setting allows the drive motor 801 to be installed inside the outer casing 1, preventing the drive motor 801 from exceeding the outer casing 1 and affecting installation and use.

[0029] As a further implementation of this solution, one end of the first support plate 805 is fixedly connected to the top of the inner wall of the outer shell 1, and the other end of the first support plate 805 does not contact the inner shell 2. The first support plate 805 can fix the drive motor 801 inside the outer shell 1 and avoid affecting the rotation adjustment of the inner shell 2.

[0030] As a further implementation of this solution, the drive gear 802 and the drive gear ring 804 are at the same height and are meshed with each other. The drive gear 802 is driven by the drive motor 801 to drive the drive gear ring 804 to mesh and rotate, thereby achieving the purpose of adjusting the rotation of the inner housing 2.

[0031] As a further implementation of this solution, a second support plate 904 is fixedly connected to the top of the outer side of the small air pump 901. The top of the second support plate 904 is not higher than the top height of the outer casing 1. The second support plate 904 can provide fixed support for the small air pump 901, and this height setting allows the small air pump 901 to be installed inside the outer casing 1, preventing the small air pump 901 from exceeding the outer casing 1 and affecting its installation and use.

[0032] As a further implementation of this solution, one end of the second support plate 904 is fixedly connected to the top outer side of the inner housing 2, and the other end of the second support plate 904 is slidably connected to the top inner side of the outer housing 1. The second support plate 904 can fix the small air pump 901 on the inner housing 2 and avoid affecting the rotation adjustment of the inner housing 2.

[0033] Workflow: First, all electrical appliances are powered on and connected to an external controller. The first through-hole 5, second through-hole 6, and third through-hole 7 provide pathways for airflow, allowing outside air to pass through the outer shell 1, the filling airbag 4, and the inner shell 2, ultimately passing through the filter element body 3 for air filtration. When adjusting the air resistance of the filter element body 3, the drive motor 801 in the adjustment assembly 8 is activated via the external controller. The drive motor 801 drives the drive gear 802 through its output end, which in turn drives the drive gear ring 804 in the mounting ring groove 803 to rotate, ultimately causing the inner shell 2 to rotate synchronously. The rotation of the inner shell 2 causes the first through-hole 5 on the outer shell 1 and the third through-hole 7 on the inner shell 2 to overlap or stagger to varying degrees. This overlap or staggering adjusts the airflow, thereby regulating the air resistance of the filter element body 3. After the position of the inner shell 2 is adjusted, the drive motor 801 stops operating. Then, the small air pump 901 in the pneumatic assembly 9 is activated via an external controller, causing the small air pump 901 to inflate the filling airbag 4 through the solenoid valve 903 and the pneumatic through-hole 902. Since the filling airbag 4 and the inner shell 2 are fixedly connected and the second through-hole 6 and the third through-hole 7 are positioned accordingly, when the filling airbag 4 is inflated, it not only fills the space between the inner shell 2 and the outer shell 1 to ensure the dustproof effect between the outer shell 1 and the inner shell 2, but also, because the filling airbag 4 is located within the inner shell 2... After adjustment, the airbag 4 is inflated, which reduces or avoids contact friction with the inner wall of the outer shell 1 when the inner shell 2 is rotated and adjusted, thus preventing damage. When the air resistance needs to be adjusted again, the same principle applies. Simply deflate the airbag 4 first through the small air pump 901 and the solenoid valve 903, then rotate the inner shell 2 through the adjustment component 8, and finally start the small air pump 901 to inflate the airbag 4 through the solenoid valve 903 and the pneumatic through hole 902.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
