Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a low-resistance, high-efficiency air filter. Background Technology

[0002] In the field of air purification, ensuring that air quality meets standards is crucial, and the performance of air filters directly affects the effectiveness of air purification.

[0003] The installation and disassembly of some traditional air filtration devices are relatively complicated, and tools are required when replacing the filter cotton, which is cumbersome and leads to low maintenance efficiency. In order to solve the above problems, this utility model provides a low-resistance high-efficiency air filter. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-resistance, high-efficiency air filter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-resistance, high-efficiency air filter includes a mounting box and a blower. The blower is housed within the mounting box, and an air outlet duct is located at the top of the mounting box, connecting to the outlet end of the blower. An air inlet box is fixedly connected to the back of the mounting box, with an air inlet duct connected to the top of the air inlet box and an exhaust duct fixedly connected to the lower end of the interior of the air inlet box, connecting to the inlet end of the blower. Several slots are provided on the back of the air inlet box, each slot housing a filter frame. The filter frame is sealed to the inner wall of the air inlet box, and a sealing plate is fixedly connected to the back of each filter frame. Filter cotton is placed on the filter frame. Installing the filter frame is as simple as inserting it into the slot on the back of the air inlet box, and removing it is as simple as pulling it out of the slot. No complicated tools or cumbersome operations are required, saving time and labor costs, improving maintenance efficiency, and making the device more convenient to use. It can quickly adapt to different air filtration needs.

[0007] As a further improvement of this utility model, a horn tube is fixedly connected to the outlet end of the blower, and the air outlet pipe is connected to the horn tube, with the opening at the end of the horn tube connected to the air outlet pipe being larger than the opening at the end connected to the blower. The blower and the air outlet pipe are connected via the horn tube, which utilizes the flared structure design of the horn tube to increase the air outlet area, reduce air velocity, decrease noise generated during airflow, and improve the comfort of the air filtration equipment.

[0008] As a further improvement of this utility model, both ends of the slot on the back of the air inlet box are rotatably connected with limiting plates to prevent the filter frame from sliding out. By rotating the limiting plates, the position of the filter frame can be easily locked and unlocked.

[0009] As a further improvement of this utility model, both sides of the back of the sealing plate are fixedly connected with L-shaped brackets that are compatible with the limiting bracket. The limiting bracket is inserted into the L-shaped bracket to limit and lock the position of the filter frame. Therefore, when the limiting bracket is locked, there is a certain gap between the limiting bracket and the back of the sealing plate of the filter frame, which is more conducive to the operator to rotate the limiting bracket.

[0010] As a further improvement of this utility model, the front of the mounting box is hinged with an inspection door, which allows for convenient maintenance when the blower malfunctions.

[0011] As a further improvement of this utility model, a handle is fixedly connected to the back of the sealing plate, which allows the filter frame to be easily pushed and pulled in the slot, making it more convenient to disassemble and assemble the filter frame.

[0012] As a further improvement of this utility model, the inner side wall of the air inlet box is fixedly connected with several U-shaped mounting seats that are compatible with the filter frame. The U-shaped mounting seats can not only position and install the filter frame to ensure structural stability, but also facilitate reliable sealing of the filter frame edge, thereby ensuring the filtration effect.

[0013] As a further improvement of this utility model, the filter cotton is made of polyester synthetic fiber. Polyester synthetic fiber has good filtration performance and durability, and can effectively intercept large particulate impurities in the air, ensuring the overall performance stability of the air filtration equipment.

[0014] The beneficial effects of this utility model are as follows: When installing the filter frame, simply insert it into the slot on the back of the air inlet box; when removing the filter frame, simply pull it out of the slot. No complicated tools or cumbersome operations are required, saving time and labor costs, improving maintenance efficiency, making the device more convenient to use, and enabling it to quickly adapt to different air filtration needs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A low-resistance, high-efficiency air filter includes a mounting box 1 and a blower 7. The blower 7 is installed inside the mounting box 1. An air outlet pipe 9 is provided at the upper end of the mounting box 1 and is connected to the outlet end of the blower 7. An air inlet box 2 is fixedly connected to the back of the mounting box 1. An air inlet pipe 10 is connected to the upper end of the air inlet box 2. An exhaust pipe 13 is fixedly connected to the lower end of the air inlet box 2 and is connected to the inlet end of the blower 7. Several slots are provided on the back of the air inlet box 2. Filter frames 3 are inserted into the slots. The filter frames 3 are sealed to the inner wall of the air inlet box 2. A sealing plate 5 is fixedly connected to the back of the filter frames 3. Filter cotton 4 is provided on the filter frames 3.

[0022] In this embodiment, a horn tube 8 is fixedly connected to the outlet end of the blower 7, and an air outlet pipe 9 is connected to the horn tube 8. The opening of the end of the horn tube 8 connected to the air outlet pipe is larger than the opening of the end connected to the blower. Compared with conventional circular pipes, the horn tube 8 can expand the air outlet area, reduce the air velocity, reduce the noise generated when the air flows, and improve the comfort of the air filtration equipment.

[0023] In this embodiment, both ends of the slot on the back of the air inlet box 2 are rotatably connected with limiting plates 12 to prevent the filter frame from sliding out. When the filter frame 3 is inserted into the slot of the air inlet box 2, the filter frame 3 and the sealing plate on its back need to form a relatively tight fit with the air inlet box 2 to ensure a reliable seal. The limiting plates 12 can stably lock the filter frame 3 in the installation and sealing position. The limiting plates 3 with a rotating setting can more easily realize the locking and unlocking operation of the filter frame position.

[0024] Furthermore, both sides of the back of the sealing plate 5 have protruding structures that can cooperate with the limiting plate 12. The overall shape of the protruding structure is L-shaped, hence it is defined as an L-shaped retainer 11. The limiting plate can cooperate with the L-shaped retainer 11 to limit and lock the position of the filter frame. Therefore, there is a certain gap between the limiting plate and the back of the sealing plate of the filter frame, avoiding direct contact between the limiting plate and the sealing plate, which would cause inconvenience in operation and high friction. This makes it easier for the operator to rotate the limiting plate. At the same time, the L-shaped retainer 11 can also accurately position the rotation of the limiting plate.

[0025] Of course, in addition to limit plates, other locking structures such as screw fixing can also be used.

[0026] In this embodiment, the front of the mounting box 1 is hinged with an inspection door 14, which allows for convenient maintenance when the blower malfunctions.

[0027] In this embodiment, a handle 15 is fixedly connected to the back of the sealing plate 5. The handle allows for easy pushing and pulling of the filter frame in the slot, making it more convenient to install and remove the filter frame.

[0028] In this embodiment, several U-shaped mounting seats 16 adapted to the filter frame 3 are fixedly connected to the inner wall of the air inlet box 2. The U-shaped mounting seats 16 provide stable support and positioning for the filter frame 3. Furthermore, a sealing strip can be provided at the edge of the filter frame 3. When the filter frame 3 is inserted into the U-shaped mounting seat, a reliable seal can be formed between the sealing strip and the U-shaped mounting seat 16.

[0029] In this embodiment, the filter cotton 4 is made of polyester synthetic fiber. Polyester synthetic fiber filter cotton 4 has good filtration performance and durability, effectively intercepting large particulate impurities in the air. At the same time, its good air permeability prevents excessive resistance to airflow, ensuring the overall stable performance of the air filtration equipment. Of course, the filter cotton 4 can also be made of other materials such as polypropylene fiber or polyamide fiber.

[0030] In this embodiment, the blower 7 is started first, and the air to be filtered is introduced into the air inlet box 2 through the air inlet pipe 10 on the upper surface of the mounting box 1. The U-shaped mounting seats 16 on both sides inside the air inlet box 2 provide positioning and support for the filter frame 3. The air is filtered by the filter cotton 4 fixedly connected inside the filter frame 3 to remove particulate impurities from the air. The filtered air is then drawn into the inlet end of the blower 7 through the exhaust pipe 13 fixedly connected to the lower end inside the air inlet box 2. The blower 7 delivers the air from its outlet end to the horn pipe 8, and then discharges it through the air outlet pipe 9 connected to the horn pipe 8, thus completing the air filtration and delivery process.

[0031] Meanwhile, when installing the filter frame, simply insert it into the slot on the back of the air inlet box, and then lock the filter frame by rotating the limiting plates on both sides of the back of the air inlet box 2. When the filter cotton 4 is clogged or damaged and needs to be replaced, unlock it by rotating the limiting plates, and then easily pull the filter frame out of the slot using the handle. The operation is very convenient, requiring no complicated tools or cumbersome procedures, saving time and labor costs, improving maintenance efficiency, making the device more convenient to use, and enabling it to quickly adapt to different air filtration needs.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
