[0001] This utility model relates to the field of air purifier technology, specifically a plasma air purifier. Background Technology

[0002] In today's society, with the acceleration of industrialization and changes in people's lifestyles, air quality problems are becoming increasingly prominent. Whether it's waste gas emitted from industrial production or various indoor and outdoor pollutants in daily life, such as particulate matter, harmful gases, bacteria, and viruses, they all pose a serious threat to human health and the ecological environment. Against this backdrop, plasma technology, as an emerging purification technology, has gradually gained attention. Plasma contains a large number of high-energy electrons, ions, free radicals, and excited-state molecules, which can undergo a series of complex physical and chemical reactions with pollutants, thereby achieving efficient decomposition, removal, and inactivation of pollutants.

[0003] Traditional plasma air purifiers can purify airborne bacteria; however, air purification typically relies on multiple filters working together. Current filters are directly installed inside the device, making easy disassembly, cleaning, and replacement impossible. Removing or installing internal filters requires disassembling the outer casing, a complex and cumbersome process. Over time, this inconvenience leads to difficulties in timely filter maintenance, negatively impacting the device's efficiency.

[0004] Therefore, it is necessary to provide a plasma purifier to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a plasma purifier to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plasma purifier, comprising:

[0008] The base has a first body fixedly installed on the front side of its top, and a second body fixedly installed on the back of the first body. Symmetrically distributed fans are provided at the connection between the first body and the second body. The top of the first body has an installation opening, and the inner wall of the first body has two U-shaped slots. A first filter plate and a second filter plate are slidably inserted into the two U-shaped slots respectively. A matching cover plate is snapped into the inside of the installation opening. The top of the second body has an air outlet window, and a switch is installed on the back of the second body. A locking mechanism is provided on the cover plate.

[0009] Support plates are fixedly installed on the front and rear sides of the inner wall of the installation opening, and the top of the support plate abuts against the bottom of the cover plate. The tops of the first filter plate and the second filter plate are flush with the top of the support plate.

[0010] The front of the first body is fixedly connected to a panel by bolts, and the front of the panel is provided with symmetrically distributed air inlet windows.

[0011] Preferably, the locking mechanism includes a mounting groove, which is located on the top of the cover plate. Positioning blocks are slidably inserted into both the front and back sides of the cover plate. The opposite ends of the two positioning blocks are located inside the mounting groove. A spring is fixedly installed between the opposite ends of the two positioning blocks. An operating plate is fixedly installed on the top of the opposite ends of the two positioning blocks. A positioning groove corresponding to the position and number of the positioning blocks is opened on the inner wall of the mounting opening, and the positioning groove is engaged with the positioning block.

[0012] Preferably, several anti-slip strips are adhered to the upper part of the opposite sides of the two operation panels.

[0013] Preferably, the top opening of the positioning block is fixedly connected to a matching fixing plate by bolts, and the top of the fixing plate has through holes corresponding to the position and number of the operating plate, and the operating plate extends through the through holes to the top of the fixing plate.

[0029] A plasma purifier, comprising:

[0030] A base 1 is provided, a first body 2 is fixedly installed on the front side of the top of the base 1, a second body 3 is fixedly installed on the back of the first body 2, symmetrically distributed fans 12 are provided at the connection between the first body 2 and the second body 3, an installation opening 13 is provided on the top of the first body 2, and two U-shaped slots 14 are provided on the inner wall of the first body 2. A first filter plate 10 and a second filter plate 11 are slidably inserted into the two U-shaped slots 14 respectively, and a matching cover plate 6 is snapped into the inside of the installation opening 13, an air outlet window 17 is provided on the top of the second body 3, a switch 18 is installed on the back of the second body 3, and a locking mechanism is provided on the cover plate 6.

[0031] Support plates 15 are fixedly installed on the front and rear sides of the inner wall of the installation opening 13, and the top of the support plate 15 abuts against the bottom of the cover plate 6. The top of the first filter plate 10 and the second filter plate 11 are flush with the top of the support plate 15. The support plate 15 can support the cover plate 6, ensuring its stable installation, and also making the filter plate installation and positioning accurate, thus improving the overall stability of the equipment.

[0032] The front of the first body 2 is fixedly connected to a panel 4 by bolts, and the front of the panel 4 is provided with symmetrically distributed air inlet windows 5.

[0033] The locking mechanism includes a mounting groove 21, which is located on the top of the cover plate 6. Positioning blocks 22 are slidably inserted into both the front and back sides of the cover plate 6. The opposite ends of the two positioning blocks 22 are located inside the mounting groove 21. A spring 23 is fixedly installed between the opposite ends of the two positioning blocks 22. An operating plate 8 is fixedly installed on the top of the opposite ends of the two positioning blocks 22. Positioning grooves 16 corresponding to the position and number of positioning blocks 22 are opened on the inner wall of the mounting opening 13. The positioning grooves 16 are engaged with the positioning blocks 22, thereby achieving stable closure of the cover plate 6 inside the mounting opening 13.

[0034] In one embodiment, several anti-slip strips 20 are attached to the upper part of the opposite sides of the two operation panels 8, which increases the friction between the user's hand and the operation panel 8, and provides the user with a more reliable grip during the operation of disassembling and assembling the cover 6.

[0035] In one preferred embodiment, a fixing plate 7 that is adapted to the positioning block 22 is fixedly connected to the top opening by bolts. The top of the fixing plate 7 is provided with through holes 19 corresponding to the position and number of the operating plate 8, and the operating plate 8 extends through the through holes 19 to the top of the fixing plate 7. The through holes 19 limit the movement path of the operating plate 8 to ensure stable operation of the operating plate 8.

[0036] In one embodiment, symmetrically distributed protrusions 9 are provided on both sides of the cover plate 6, and the protrusions 9 are slidably connected to the corresponding U-shaped grooves 14, which can close the part of the U-shaped grooves 14 extending into the installation opening 13, prevent impurities from entering the groove, and ensure the stability of the filter plate installation and the sealing of the equipment.

[0037] In one preferred embodiment, the opposite ends of the two positioning blocks 22 are inclined, and the positioning blocks 22 are adapted to the positioning grooves 16, which facilitates the quick installation of the cover plate 6.

[0038] The working principle of this utility model is as follows: All electrical components mentioned in this application are externally connected to a power supply and switch 18 during use. Parts not mentioned in this device are the same as or can be implemented using existing technology. During use, the fan 12 is started via switch 18. The operation of the fan 12 creates a negative pressure inside the first body 2, causing airflow around the device to be drawn in through the air inlet window 5. The air passes through the first filter plate 10 and the second filter plate 11 sequentially before entering the second body 3. There, a plasma generator located inside the second body 3 sterilizes and disinfects the air. Finally, the purified air is discharged through the air outlet window 17, completing the air purification process. As the device continues to operate, the impurities trapped by the first filter plate 10 and the second filter plate 11 gradually increase, requiring periodic cleaning or replacement. When cleaning or replacing these two filter plates is required, the user directly presses the two operating plates 8 to move them relative to each other. The movement of the operating plates 8 causes the positioning block 22 to move synchronously relative to each other, compressing the spring 23. As the positioning block 22 moves, its engagement with the positioning groove 16 on the inner wall of the mounting opening 13 is released. At this point, the cover plate 6 can be removed from the mounting opening 13 via the operating plate 8. Subsequently, the user can directly pull out the first filter plate 10 and the second filter plate 11 from the U-shaped slot 14 through the mounting opening 13, completing the disassembly of the filter plates from the inside of the first body 2. After cleaning or replacing the filter plates, the first filter plate 10 and the second filter plate 11 are inserted into the U-shaped slot 14 through the mounting opening 13, and installed into the inside of the first body 2. Next, the cover plate 6 is placed in the mounting opening 13. At this time, the inclined end of the positioning block 22 will abut against the inner wall of the mounting opening 13. During the process of applying external force to install the cover plate 6, the positioning block 22 will automatically move into the mounting groove 21 and compress the spring 23 until the cover plate 6 is engaged with the mounting opening 13. At this time, the positioning block 22 is inserted into the positioning groove 16 under the elastic restoring force of the spring 23, which firmly limits the cover plate 6 in the installation opening 13 and makes it abut against the top of the first filter plate 10 and the second filter plate 11, thus ensuring the stability of the filter plates in the first body 2.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
