Description

Technical Field

[0001] This utility model relates to the field of ventilation duct technology, specifically to a ventilation duct with air purification function. Background Technology

[0002] Ventilation ducts, or simply ducts, are metal or composite pipes used in ventilation and air conditioning systems for industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases.

[0003] Existing ventilation ducts can effectively exchange indoor and outdoor air by properly setting up air inlets and outlets. However, in actual operation, outdoor air may contain pollutants such as particulate matter and dust. Some of these dust particles will settle and accumulate on the inner wall of the duct if they directly enter the duct, causing secondary pollution to the air when it flows, thereby reducing air quality.

[0004] For example, an energy-saving ventilation duct disclosed in patent CN218475027U has a filter screen to filter the air. However, a single-layer filter screen may not be able to effectively filter out all pollutants in the air, especially fine particulate matter and harmful gases. This may result in poor indoor air quality and failure to achieve the expected air purification effect. In addition, the filter screen in this patent is fixedly installed inside the installation frame. After long-term use, the filter screen may be damaged. However, due to its fixed installation method, it is not convenient to disassemble, replace and maintain it.

[0005] Therefore, it is necessary to invent a ventilation duct with air purification function to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a ventilation duct with air purification function to solve the problems of the current technology, which cannot effectively filter out all pollutants in the air, cannot achieve the expected air purification effect, and is inconvenient to disassemble, replace and maintain the filter.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ventilation duct with air purification function, comprising a duct body, a mounting frame, a first filter, and a second filter. An mounting plate is provided at the air inlet end of the duct body. An air inlet pipe is provided on one side of the mounting plate, and a cover plate is provided on one side of the air inlet pipe. The mounting frame slides inside the air inlet pipe. A first filter, a second filter, and an activated carbon filter are provided inside the mounting frame. Mounting sliders are provided on the side walls of the first filter, the second filter, and the activated carbon filter. Mounting grooves are provided at the contact points between the inner wall of the mounting frame and the mounting sliders.

[0008] Preferably, the air inlet pipe and the cover plate are connected by a snap-fit ​​connection, and a hinge is provided on one side of the air inlet pipe and the cover plate. The air inlet pipe and the cover plate are hinged by the hinge, so that the cover plate can be opened and closed easily, which facilitates the maintenance of the filter.

[0009] Preferably, the air inlet pipe is provided with a latch on the other side of the cover plate, and the latch further ensures the stability of the cover plate when closed.

[0010] Preferably, the cover plate is provided with a filter window, which is made of synthetic fiber filter material and can purify the air entering the pipe body first.

[0011] Preferably, the side wall of the mounting bracket is provided with a T-shaped slider, and a T-shaped groove is provided at the contact position between the inner wall of the air inlet pipe and the T-shaped slider. The T-shaped slider and the T-shaped groove are slidably connected, so that the mounting bracket can be easily slid into and out of the air inlet pipe, which facilitates the maintenance of the entire air purification system.

[0012] Preferably, the No. 1 filter, No. 2 filter, and activated carbon filter are arranged vertically from the outside to the inside. This layered design can more effectively remove particles of different sizes and harmful gases from the air.

[0013] Preferably, the second filter screen is located between the first filter screen and the activated carbon filter screen, and the pore size of the second filter screen is smaller than that of the first filter screen. Filter screens with different pore sizes can achieve multi-stage filtration.

[0014] Preferably, the mounting slider and the mounting groove are slidably connected, and the mounting slider and the mounting groove cooperate with each other to achieve a slidable connection, which facilitates the installation, disassembly and replacement of the No. 1 filter screen, the No. 2 filter screen and the activated carbon filter screen.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model has a No. 1 filter, a No. 2 filter, and an activated carbon filter installed inside the pipe body. The No. 1 filter, the No. 2 filter, and the activated carbon filter are distributed from the outside to the inside at the air inlet pipe, forming a progressive filtration system. The progressive filtration system ensures that the air is fully purified when passing through the pipe. Whether it is large particles, small particles, or harmful gases and odors, they can be effectively removed, ensuring further improvement in air purification quality.

[0017] 2. In this utility model, the No. 1 filter, the No. 2 filter, and the activated carbon filter are slidably mounted on the mounting frame via mounting sliders and mounting grooves. The mounting frame is also slidably mounted inside the air inlet pipe via T-shaped sliders and T-shaped grooves, allowing the No. 1 filter, the No. 2 filter, and the activated carbon filter to be disassembled and replaced individually, effectively improving the flexibility and convenience of replacing the No. 1 filter, the No. 2 filter, and the activated carbon filter.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The ventilation duct shown includes a duct body 1, a mounting bracket 8, a first filter 11, a second filter 12, and an activated carbon filter 13. The air inlet end of the duct body 1 is provided with a mounting plate 2, an air inlet pipe 3 is provided on one side of the mounting plate 2, and a cover plate 4 is provided on one side of the air inlet pipe 3. The mounting bracket 8 slides inside the air inlet pipe 3. The first filter 11, the second filter 12, and the activated carbon filter 13 are provided inside the mounting bracket 8. The side walls of the first filter 11, the second filter 12, and the activated carbon filter 13 are all provided with mounting sliders 14. The inner wall of the mounting bracket 8 is provided with a mounting groove 15 at the contact position with the mounting slider 14.

[0027] The air inlet pipe 3 and the cover plate 4 are connected by a snap-fit ​​connection. A hinge 6 is provided on one side of the air inlet pipe 3 and the cover plate 4. The air inlet pipe 3 and the cover plate 4 are hinged together by the hinge 6. A latch 7 is provided on the other side of the air inlet pipe 3 and the cover plate 4. A filter window 5 is provided on the cover plate 4. The filter window 5 is made of synthetic fiber filter material.

[0028] The hinge 6 allows the cover plate 4 to rotate around the hinge 6 axis, achieving a hinged function. This allows the cover plate 4 to be easily opened or closed, facilitating daily maintenance and cleaning. The latch 7 ensures that the cover plate 4 is firmly fixed to the air inlet pipe 3, preventing it from being opened accidentally. Furthermore, a filter window 5 made of synthetic fiber filter media is installed on the cover plate 4. This filter media has good filtration performance and can perform initial filtration of the air entering the pipe body 1.

[0029] The side wall of the mounting bracket 8 is provided with a T-shaped slider 9. A T-shaped groove 10 is provided at the contact position between the inner wall of the air inlet pipe 3 and the T-shaped slider 9. The T-shaped slider 9 and the T-shaped groove 10 are slidably connected. The first filter screen 11, the second filter screen 12 and the activated carbon filter screen 13 are arranged vertically from the outside to the inside. The second filter screen 12 is located between the first filter screen 11 and the activated carbon filter screen 13. The pore size of the second filter screen 12 is smaller than that of the first filter screen 11. The mounting slider 14 and the mounting groove 15 are slidably connected and cooperate with each other.

[0030] The T-shaped slider 9 is designed with a T-shaped groove 10 on the inner wall of the air inlet pipe 3. This design allows the mounting bracket 8 to easily slide into or out of the air inlet pipe 3 along the T-shaped groove 10, which facilitates the cleaning and replacement of the No. 1 filter 11, No. 2 filter 12, and activated carbon filter 13 in the mounting bracket 8. The arrangement of the No. 1 filter 11, No. 2 filter 12, and activated carbon filter 13 helps air pass through different levels of filters in sequence, achieving a multi-stage filtration effect. At the same time, the mounting slider 14 and the mounting groove 15 are slidably connected, ensuring that the No. 1 filter 11, No. 2 filter 12, and activated carbon filter 13 are easily installed and removed from the mounting bracket 8, thereby reducing maintenance costs and management difficulty.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual appendix Figure 1-2When using this utility model, when the ventilation duct starts working, the outside air first enters the air inlet pipe 3 through the mounting plate 2 at the air inlet end. Before the air enters the air inlet pipe 3, it encounters the filter window 5 to preliminarily filter the impurities in the air. After the air passes through the preliminarily filtered air, it first encounters the first filter screen 11. The first filter screen 11 usually has a larger pore size to block larger particles, such as dust and hair. After the air passes through the first filter screen 11, it continues to flow inward and encounters the second filter screen 12. The pore size of the second filter screen 12 is smaller than that of the first filter screen 11, which can further trap smaller particles, such as pollen and bacteria. Finally, the air passes through the activated carbon filter screen 13. The activated carbon filter screen 13 has a strong adsorption capacity and can remove harmful gases, odors and other pollutants in the air to achieve deep purification. The clean air after three stages of filtration is finally discharged through other parts of the duct body 1, such as the air outlet, and enters the room or designated area.

[0033] Refer to the instruction manual appendix Figure 3-5 When using this utility model, if the No. 1 filter 11, No. 2 filter 12 and activated carbon filter 13 need to be cleaned or replaced after long-term use, the latch 7 can be unlocked, the cover plate 4 on the air inlet pipe 3 can be opened, and then the mounting bracket 8 can be gently pulled to slide outward along the T-shaped slide groove 10 until it is completely out of the air inlet pipe 3. After the mounting bracket 8 slides out, the No. 1 filter 11, No. 2 filter 12 and activated carbon filter 13 can be pulled upward respectively, so that the mounting slider 14 slides out of the mounting bracket 8 along the mounting slide groove 15. This makes it easy to disassemble and install the No. 1 filter 11, No. 2 filter 12 and activated carbon filter 13, which is convenient for daily maintenance and cleaning.
