Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an energy-saving and high-efficiency air purification device and a fan coil unit with purification function. Background Technology

[0002] Air purification devices are widely used for indoor environmental control. Traditional purification technologies mainly include media filtration and electrostatic purification. Media filtration technology has high air resistance due to the filter structure, requiring frequent filter media replacement, increasing operating costs and generating a large amount of non-reusable consumables, which is not environmentally friendly. Although traditional electrostatic purification technology reduces consumables, it is prone to sparking, generates high concentrations of ozone, and is difficult to clean and maintain, with a shorter equipment lifespan, making it unsuitable for long-term stable operation.

[0003] Micro-electrostatic air purification technology combines the advantages of media filtration and electrostatic purification, achieving efficient dust removal, sterilization, and disinfection. It also boasts advantages such as low energy consumption, low air resistance, resistance to high humidity, high safety, reusability, and no consumables, with a service life exceeding 10 years. However, existing micro-electrostatic purification devices on the market have limitations in installation methods and spatial adaptability, making it difficult to meet the needs of different equipment. Furthermore, their discharge forms are singular, failing to fully optimize the electrostatic field structure to improve purification efficiency.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide an energy-saving and efficient air purification device and a fan coil unit with purification function, so as to solve the technical problems of simple installation method and inconvenient maintenance of micro-electrostatic air purification devices in related technologies.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: an energy-saving and efficient air purification device is provided, including a frame and a module group for purifying air through micro-electrostatic dust removal. The frame includes a first frame, a second frame, and a movable plate. The first frame, the second frame, and the movable plate are sequentially connected to form a placement cavity. An electrical box is provided inside the first frame. The electrical box is electrically connected to the module group and connected to an external power source through a power line.

[0007] Furthermore, the second frame includes an L-shaped frame and a surrounding rod. One end of the L-shaped frame is connected to the first frame, and the other end of the L-shaped frame is connected to the surrounding rod, with the other end of the surrounding rod connected to the first frame.

[0008] Furthermore, it also includes at least two first limiting plates, which are rotatably mounted on the L-shaped frame and the surrounding rod, respectively. When the module group is inserted into the placement cavity from the front, the first limiting plates are rotated to form an angle with the second frame, thereby limiting the module group from the windward side of the module group.

[0009] Furthermore, the second frame is also provided with a first shelf groove, and the first limiting piece can be rotated to move out of or into the first shelf groove.

[0010] Furthermore, there are two retaining rods spaced apart to form an opening for the module group to enter and exit. When the second frame is connected to the movable plate, the two sides of the movable plate are respectively attached to the two retaining rods to block the opening. The energy-saving and high-efficiency air purification device also includes a second limiting plate, which is rotatably mounted on the first frame. Rotating the second limiting plate limits the module group from the windward side. The length extension direction of the first limiting plate is perpendicular to the length extension direction of the second limiting plate.

[0011] Furthermore, the movable plate is detachably connected to the first frame and the second frame. When the movable plate is detached, the module assembly can be inserted into or removed from the placement cavity from the side of the frame.

[0012] Furthermore, it also includes at least two pairs of third limiting plates, each pair of which is rotatably mounted on two surrounding bars. When the module group is inserted into the placement cavity from the side, the third limiting plate is rotated to enter the opening, thereby limiting the module group from one side of the opening.

[0013] Furthermore, a second placement groove is provided on the railing, and the third limiting plate is rotated to move out of or into the second placement groove; a limiting plate is provided on the first frame, and the two ends of the limiting plate are connected to the L-shaped frame and the railing respectively. When the module group is inserted into the placement cavity from the side of the frame, the limiting plate limits the module group.

[0014] Furthermore, the module group includes a pre-filter, an electric field module, and a micro-electrostatic module. The air first passes through the pre-filter, and then is purified by the electrostatic dust removal effect of the electric field module and the micro-electrostatic module. The electric field module is equipped with electrode heads for discharge. The electric field module includes two electrode discharge methods: vertical discharge method, in which the electrode head is arranged perpendicular to the plane of the frame; and non-vertical discharge method, in which the electrode head is arranged at an angle greater than or equal to 0 degrees and less than or equal to 75 degrees to the plane of the frame.

[0015] A fan coil unit with purification function includes the energy-saving and high-efficiency air purification device as described above, and a connecting plate is provided on the outer edge of the frame, which is connected to the fan coil unit.

[0016] Beneficial effects:

[0017] 1. This utility model's energy-efficient air purification device has two installation and disassembly methods: front and side. Through the design of a detachable movable plate and a module insertion structure, the module assembly can be easily inserted into and removed from the placement cavity from either the front or side. This design makes the equipment more flexible during installation and daily maintenance, allowing users to choose the appropriate installation method according to their actual situation, facilitating quick disassembly and cleaning.

[0018] 2. By designing multiple limiting plates in the device, the limiting plates can effectively prevent displacement, tilting or falling during use after the module group is installed, ensuring stable operation of the module group and improving the service life of the equipment.

[0019] 3. The two electrode discharge methods of the field electric module provide different electric field distribution forms, which can optimize the air purification effect according to actual needs and enhance the adaptability and working efficiency of the purification device.

[0020] 4. The air passing through the fan coil unit is purified by an energy-efficient air purification device, which avoids contaminating the fan coil unit, affecting the heat exchange effect, and saving energy. Attached Figure Description

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] According to an embodiment of this utility model, an energy-saving and high-efficiency air purification device is provided. Please refer to [link / reference]. Figures 1 to 8 The system includes a frame 1 and a module assembly 2 for purifying air through micro-electrostatic dust removal. The frame 1 includes a first frame 11, a second frame 12, and a movable plate 13. The first frame 11, the second frame 12, and the movable plate 13 are sequentially connected to form a placement cavity 14. An electrical box is located inside the first frame 11, which is electrically connected to the module assembly 2 and connected to an external power source via a power line. In this design, the module assembly 2, capable of purifying air through micro-electrostatic dust removal, is placed in the middle of the frame 1. The movable plate 13 is detachably connected to the first frame 11 and the second frame 12. Users can choose to install or remove the module assembly 2 from the front or side of the frame based on the available space and actual conditions. When the movable plate 13 is connected to the first frame 11 and the second frame 12, the module assembly 2 can be inserted into the placement cavity 14 from the front of the frame 1 (e.g., ...). Figure 1 The installation operation shown is obtained Figure 2 (The presented usage state); when it is not easy to install module group 2 from the front of frame 1, remove the movable plate 13 on one side of frame 1, and insert module group 2 into the placement cavity 14 from the side of frame 1 (e.g. Figure 4 The installation operation shown is obtained Figure 5(The presented usage status). This design provides multiple installation options, allowing module group 2 to be installed from multiple directions, making the equipment more flexible in spatial layout and installation and daily maintenance. Users can choose the appropriate installation method according to the actual situation, facilitating quick disassembly and cleaning. The energy-efficient air purification device in this embodiment solves the technical problems of limited installation methods and inconvenient maintenance in related technologies for micro-electrostatic air purification devices.

[0033] An electrical box is provided inside the first frame 11. A high-voltage power supply is installed on the corresponding side of the micro-electrostatic dust removal and air purification module group 2 in a built-in manner. After the module group 2 is installed in the placement cavity 14, the module group 2 and the frame 1 are electrically connected, and the air is purified by micro-electrostatic dust removal.

[0034] See Figure 1 and Figure 3 In this embodiment of the energy-saving and high-efficiency air purification device, the second frame 12 includes an L-shaped frame 121 and a surrounding rod 122. One end of the L-shaped frame 121 is connected to the first frame 11, and the other end of the L-shaped frame 121 is connected to the surrounding rod 122. The other end of the surrounding rod 122 is connected to the first frame 11. The first frame 11, the second frame 12, and the movable plate 13 form a square placement cavity 14, which provides the maximum space for the micro electrostatic dust removal module to purify the area.

[0035] See Figure 3 The energy-saving and efficient air purification device of this embodiment also includes at least two first limiting plates 31. The at least two first limiting plates 31 are rotatably mounted on the L-shaped frame 121 and the surrounding rod 122 respectively. When the module group 2 is inserted into the placement cavity 14 from the front of the frame 1, the first limiting plate 31 is rotated to form an angle with the second frame 12, so that the first limiting plate 31 limits the module group 2 from the windward side of the module group 2, preventing the module group 2 from tilting and enhancing the stability of the module group 2 in the device.

[0036] See Figure 3 In this embodiment of the energy-efficient air purification device, the second frame 12 is further provided with a first shelf groove 32. The first limiting plate 31 can be rotated to move out of or into the first shelf groove 32. When the first limiting plate 31 is not in the limiting state, it can be rotated and stored in the first shelf groove 32. This not only makes the device look neater, but also avoids the interference that the limiting plate may cause outside the device. By moving the limiting plate by rotation, the limiting or releasing operation can be completed simply by rotating the limiting plate into or out of the shelf groove, greatly simplifying the use process.

[0037] See Figure 3The energy-efficient air purification device of this embodiment also includes a second limiting plate 33, which is rotatably mounted on the first frame 11. Rotating the second limiting plate 33 limits the module group 2 from the windward side. The length extension direction of the first limiting plate 31 is perpendicular to the length extension direction of the second limiting plate 33. By setting the second limiting plate 33 on the first frame 11 and forming a vertical arrangement with the first limiting plate 31 on the second frame 12, multiple limiting protections are provided for the module group 2.

[0038] See Figure 4 and Figure 6 In this embodiment of the energy-efficient air purification device, after the movable plate 13 is disassembled, the module group 2 can be inserted into or removed from the placement cavity 14 from the side of the frame 1. At this time, there are two surrounding rods 122, which are spaced apart to form an opening 15 for the module group 2 to enter and exit. When the second frame 12 is connected to the movable plate 13, the two sides of the movable plate 13 are respectively attached to the two surrounding rods 122 to seal the opening 15. The energy-efficient air purification device also includes at least two pairs of third limiting plates 34. Each pair of third limiting plates 34 is rotatably mounted on the two surrounding rods 122. When the module group 2 is inserted into the placement cavity 14 from the side, the third limiting plate 34 is rotated to enter the opening 15, thereby limiting the module group 2 from one side of the opening 15. The surrounding rods 122 are spaced apart to form the opening 15, so that the module group 2 can be easily inserted into the placement cavity 14 from the side. At least two pairs of third limiting plates 34 are rotatably mounted on the two surrounding bars 122. When the module group 2 is inserted, the third limiting plates 34 are rotated to enter the opening 15, thereby limiting the module group from one side of the opening.

[0039] See Figure 6 In this embodiment of the energy-efficient air purification device, the retaining rod 122 is also provided with a second shelf groove 35. The third limiting plate 34 can be rotated to move out of or into the second shelf groove 35. The second shelf groove 35 has the same function as the first shelf groove 32. When the third limiting plate 34 is not in the limiting state, it can be rotated and stored in the second shelf groove 35, which is neat and beautiful and avoids operational interference.

[0040] A toggle piece 37 is provided on the first limiting piece 31, the second limiting piece 33 and the third limiting piece 34. The limiting pieces can be rotated by pressing or pulling the toggle piece 37, which is easy and convenient to operate.

[0041] See Figure 5 and Figure 6In this embodiment of the energy-efficient air purification device, a limiting plate 36 is provided on the first frame 11. The two ends of the limiting plate 36 are respectively connected to the L-shaped frame 121 and the surrounding rod 122. When the module group 2 is inserted into the placement cavity 14 from the side of the frame 1, the limiting plate 36 limits the module group 2. After the module group 2 is inserted from the side of the frame 1, the limiting plate 36, as a fixed limiting structure, can effectively restrict the movement of the module group 2 within the placement cavity 14 from one side.

[0042] See Figure 1 , Figure 4 , Figure 7 and Figure 8 This embodiment of the energy-efficient air purification device includes module group 2, which comprises a pre-filter 21, an electrostatic module 22, and a micro-electrostatic module 23. Air is first filtered by the pre-filter 21, and then purified through the electrostatic removal process of the electrostatic module 22 and the micro-electrostatic module 23. The electrostatic module 22 is equipped with electrode heads 223 for discharge. The electrostatic module 22 includes two electrode discharge methods: a vertical discharge method, where the electrode heads 223 are arranged perpendicularly to the plane of the frame 1; and a non-vertical discharge method, where the electrode heads 223 are arranged at an angle to the plane of the frame 1. The air first passes through the pre-filter 21, which removes large particles such as dust and pet hair, providing pretreatment for the subsequent electrostatic removal. The pre-filter, as the first line of defense, effectively reduces the processing burden on subsequent modules. The electrostatic removal process of the electrostatic module 22 and the micro-electrostatic module 23 further removes fine particulate matter from the air, improving air purification efficiency. The field electric module 22 employs two electrode discharge methods, allowing users to flexibly select one of the discharge methods based on air quality and particulate matter size.

[0043] In this embodiment of the energy-efficient air purification device, the field electric module 22 adopts a non-vertical discharge method, meaning that the arrangement direction of the electrode heads 223 forms an angle with the plane of the frame 1. Preferably, the angle is greater than or equal to 0 degrees and less than or equal to 75 degrees. When the angle is equal to 0 degrees, the arrangement direction of the electrode heads 223 is parallel to the plane of the frame 1, that is, the field electric module 22 discharges horizontally, and the arrangement direction of each electrode head 223 is parallel to the plane of the frame 1 and also parallel to the plane of the conductive plate 222 (e.g., ...). Figure 7 (As shown); the angle between the electrode head 223 and the plane of the frame 1 can be any angle greater than 0 degrees and less than or equal to 75 degrees. This arrangement is beneficial for the effective charging of airborne particles, thus improving air purification efficiency. The electrode heads 223 are distributed at intervals on the discharge rod 221. They can appear in pairs on both sides of the discharge rod 221, or they can be arranged alternately and at equal intervals on both sides of the discharge rod 221.

[0044] See Figure 8 In this embodiment of the energy-efficient air purification device, when the field power module 22 discharges vertically, the arrangement direction of each electrode head 223 is perpendicular to the plane where the conductive plate 222 is located. The electrode heads discharge evenly into the holes opened in the conductive plate 222, resulting in more uniform charging of particulate matter.

[0045] The electrode head 223 can be any structural form, such as a carbon fiber brush, a bundle of metal wires, or a metal tip. When horizontal discharge is used, the electrode head 223 can be perpendicular to the discharge rod 221, or the two can be at an angle. The shape of the hole on the discharge rod 221 for mounting the electrode head 223 can be circular, elliptical, square, or have rounded corners.

[0046] See Figure 2 and Figure 6 The fan coil unit with purification function in this embodiment includes the energy-efficient air purification device described above. A connecting plate 16 is provided on the outer edge of the frame 1, and the connecting plate 16 is connected to the fan coil unit 4, so that the energy-efficient air purification device can be stably installed on the fan coil unit 4 and the purified air is passed through the fan coil unit. The energy-efficient air purification device of this embodiment can be installed on the fan coil unit by front installation or side installation. It is convenient and flexible for both assembly and maintenance, purifies the air passing through the fan coil unit 4, avoids contamination of the fan coil unit and affects the heat exchange effect, and saves energy.

[0048] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
