[0027] Compared with the prior art, the negative ion air purification device disclosed by the present utility model adopts the following technical means and the corresponding technical effects are as follows:

[0028] 1. Since the negative ion generator and the electrostatic dust removal plate 5 are respectively limited and installed in the first installation cavity and the second installation cavity on two opposite side surfaces of the insulating bracket 1, the insulating middle plate 11 of the insulating bracket 1 is used to physically isolate and install the negative ion generator and the electrostatic dust removal plate 5, avoiding the high voltage of the negative ion generator from posing a potential safety hazard during the regular disassembly, assembly and cleaning operation of the electrostatic dust removal plate, thereby improving the use safety of the negative ion air purification device.

[0029] 2. The negative ion generator and the electrostatic dust removal plate 5 are respectively limited and fixed in the first installation cavity and the second installation cavity on two opposite side surfaces of the insulating bracket 1 by the first cover plate 4 and the second cover plate 6 that are detachably connected to the insulating bracket 1, simplifying the assembly structure of the negative ion air purification device, and the electrostatic dust removal plate 5 can be taken out for regular disassembly and cleaning operation by removing the second cover plate 6. The assembly operation is simple and convenient for users.

[0030] In some embodiments, a number of fixing grooves 15 are provided on the inner side surface of the frame 10; first buckles 42 and second buckles 62 are respectively provided on the peripheries of the first cover plate 4 and the second cover plate 6. The first cover plate 4 is detachably connected to the insulating bracket 1 by buckling the first buckle 42 with the top end of the fixing groove 15, and the second cover plate 6 is detachably connected to the insulating bracket 1 by buckling the second buckle 62 with the bottom end of the fixing groove 15.

[0031] Among them, the electrostatic dust removal plate 5 has a number of electrostatic grids 50, and each electrostatic grid 50, each first air hole 12 and each third air hole 61 are arranged in a one-to-one correspondence in a straight line. This structure facilitates the smooth passage of air through the first air hole 12, the electrostatic grid 50 and the third air hole 61 in the first installation cavity, which is conducive to improving the air purification efficiency.

[0032] On the side of the insulating middle plate 11 located in the second installation cavity, a number of socket connectors 18 are provided. One end of the electrostatic dust removal plate 5 is inserted into the socket connector 18, and the other end abuts against the second cover plate 6. During assembly, one end of the electrostatic dust removal plate 5 is inserted into the socket connector 18 for positioning, and then the second cover plate 6 is assembled on the insulating bracket 1. By using the abutting limit of the second cover plate 6 against the other end of the electrostatic dust removal plate 5, the electrostatic dust removal plate 5 is limited and fixed in the second installation cavity. The assembly structure is simple and is conducive to the disassembly and assembly of the electrostatic dust removal plate 5 during use to regularly clean the dust adsorbed on the electrostatic dust removal plate 5.

[0033] In some preferred embodiments, the electrostatic dust removal plate 5 includes a number of horizontally arranged electrostatic plates 51 arranged at equal intervals and a number of vertically arranged electrostatic plates 52 arranged at equal intervals. Each horizontal electrostatic plate 51 is orthogonally connected to all vertical electrostatic plates 52, and a number of electrostatic grids 50 are jointly enclosed by any two adjacent horizontal electrostatic plates 51 and any two adjacent vertical electrostatic plates 52.

Using a number of limiting columns 14 with the same height enables the same height to be maintained between different positions of the tip electrode plate 3 and different positions of the mesh electrode plate 2, which is beneficial for the negative ion generator to form a stable high-voltage electric field to improve the generation efficiency of negative ions.

[0040] In addition, a number of fixing columns 13 are provided on the insulating middle plate 11, and the mesh electrode plate 2 is correspondingly provided with a number of fixing holes 23. Each fixing column 13 correspondingly passes through one of the first fixing holes 23, and the top end of the fixing column 13 has a limiting end with a size larger than the first fixing hole 23. For example, the insulating bracket 1 is integrally formed of plastic. During assembly, after passing the fixing column 13 through the first fixing hole 23 of the mesh electrode plate 2, the top end of the fixing column 13 is melted by an electric soldering iron to form a limiting end, so that the mesh electrode plate 2 is limited and fixed on the insulating middle plate 11.

[0041] Furthermore, the tip electrode plate 3 includes a number of electrode strips 31 arranged at equal intervals and connecting strips 32 that fixedly connect the a number of electrode strips 31. A number of discharge parts 33 are evenly spaced on each electrode strip 31, and discharge tips 331 extending in the same direction towards the mesh electrode plate 2 are provided at both ends of each discharge part 33.

[0042] On the electrode strip 31 or / and the connecting strip 32, a number of second fixing holes 34 are provided corresponding to the fixing columns 13, and the tip electrode plate 3 is fixed on the insulating middle plate 11 by passing a fixing element or the like through the second fixing holes 34 and fixedly connecting with the fixing columns 13.

[0043] Moreover, each discharge tip 331 is respectively arranged directly opposite the center of one of the ion overflow holes 21, which is beneficial for improving the working efficiency of the negative ion generator.
