[0062] The technical solution adopted by the present invention will be further described below in conjunction with the schematic diagram.

[0063] like Figure 1-Figure 9 A negative ion air machine includes: a control panel 1, an ion active oxygen generator 2, an intermediate filter body 3, a lower shell 4, an upper shell 5, a base 6, a hanging body 7, a ceiling fixing seat 8, and a fan 9.

[0064] See also Figure 10-Figure 14The base 6 has a first annular shell 601, a second annular shell 602 arranged at the lower part of the first annular shell and having a plurality of strip holes (e.g., rectangular holes) arranged circumferentially, a grid-like bottom 603 arranged at the bottom of the second annular shell, and an annular shoulder 604 arranged at adjacent positions of the first annular shell and the second annular shell. The side wall of the first annular shell 601 is located just above the annular shoulder and just protrudes from the negative ion air machine, so that the power board can be mounted here for easy maintenance, installation, and efficient heat dissipation. This is because the first annular shell is surrounded by a circle of air inlet structures outside, which can efficiently take away the heat generated by the internal equipment of the first annular shell. The annular shoulder is arranged circumferentially with a plurality of openings, which are rectangular openings with semicircular openings at both ends of the rectangular opening. This structure makes the air inlet part of the entire negative ion air machine more concealed, and the flow of air entering the negative ion air machine is more balanced. The opening is arranged in an annular array on the annular shoulder and serves as the air inlet structure of the entire negative ion air machine. A sealing cover 605 is provided on the top of the first annular shell, and a side wall of the second annular shell is provided with an outwardly protruding light-transmitting plate clamping protrusion 606, which is a hollow square protrusion. A power supply fixing bracket 607 is provided near the first annular shell of the second annular shell. The power supply fixing bracket 607 here is a circular plate-shaped structure. A power supply board 608 is installed in the inner cavity of the first annular shell isolated by the power isolation bracket 607. The power supply board can be fixed to the power supply fixing bracket by screws, and a bearing column for fixing the power supply board is provided on the power supply board isolation bracket, and a threaded hole is provided in the bearing column. An intermediate filter body limiting ring 609 is provided at the bottom of the second annular shell. The intermediate filter body limiting ring is an intermittent ring, that is, a There are three cocircular arc-shaped protrusions. The ion network limiting module here can not only prevent the installed equipment from touching the bottom of the second annular shell, but also use the step-like structure formed by the intermediate filter body limiting ring and the bottom edge of the second annular shell to complete the docking and installation of the first annular upper protrusion of the upper shell. The lower part of the second annular shell is annularly installed with an LED light-transmitting plate 610 that is snap-fitted and fixed to the snap-fitting protrusion of the light-transmitting plate. The LED light-transmitting plate 610 is a circular ring structure. This circular ring structure just serves to block the possibility of the incoming air moving further downward, and can only enter the inner cavity of the second annular shell along the long strip hole provided in the second annular shell 602. A snap-fitting groove that cooperates with the snap-fitting protrusion is installed on the LED light-transmitting plate 610. The snap-fitting groove includes but is not limited to being formed by two groove plates protruding from the LED light-transmitting plate. The snap-fitting groove and the snap-fitting protrusion here are tightly fitted.

[0065] Considering the connection between the base and the upper shell, see Fig.10Three groups of upper shell connection studs 603 - 1 are provided on the grid-shaped bottom 603 of the base. The three upper shell connection studs are arranged in a circular array on the surface of the grid-shaped bottom 603 and are distributed close to the side wall of the base.

[0066] It is worth mentioning that see Figure 15-16 The power supply fixing bracket 607 includes a circular plate-shaped portion 607-1 and an upward docking column 607-2 arranged on the circular plate-shaped portion. Correspondingly, the cover 605 is provided with a socket circular cylinder 605-1 that cooperates with the upward docking column and has a socket hole therein. In this way, after the power board is installed in place, the upward docking column of the power supply fixing bracket can be directly inserted into the socket circular cylinder to fix the power supply fixing bracket. This is not only conducive to assembly, but also allows the circular plate-shaped portion of the power supply fixing bracket to divide the inner cavity of the base into two to achieve functional zoning. A hanging body through hole 605-2 is provided at the center position of the cover. The center position can avoid the unstable center of gravity of the negative ion air machine, and arranging the hanging body through hole at the center position of the cover can effectively solve this problem. In addition, this hanging body can pass through the power board and be directly connected to the power supply fixing bracket, and the socket-jointed structure of the power supply fixing bracket can effectively ensure the relative stability and structural strength between the power supply fixing bracket and the base.

[0067] See also Figure 17-Figure 22The annular shoulder of the base is equipped with a cylindrical upper shell 5, and the outer edge of the annular shoulder is provided with a close-fitting annular side wall 604-1 extending downward and close to the inner wall of the upper shell. The close-fitting annular side wall can increase the structural strength of the annular shoulder and prevent the structure from being greatly deformed, and can improve the sealing effect between the close-fitting annular side wall and the inner wall of the upper shell by increasing the contact area between the close-fitting annular side wall and the inner wall of the upper shell. The upper shell has a first cylindrical shell 501, a first step-shaped assembly part 502 arranged at the bottom of the first cylindrical shell, a first annular plate 503 arranged inside the first step-shaped assembly part, and a first annular upper protrusion 504 arranged at the inner edge of the first annular plate. A hanging interface 501-1 is provided at the bottom of the first cylindrical shell 501. The hanging interface 501-1 enters the clamping position of the hanging interface after rotating clockwise for a certain angle. The outer surface of the first cylindrical shell is a user-visible surface. The first annular upper protrusion extends upward to the step-shaped structure formed by the intermediate filter body limit ring and the edge of the base. An inner connecting ring 504-1 is arranged on the top of an annular protrusion, and the inner side surface of the inner connecting ring 504-1 can be abutted against the outer wall of the intermediate filter body limiting ring, so as to improve the structural strength of the internal structure installation of the upper shell, and the inner connecting ring 504-1 is provided with an intermediate filter body fixing protrusion 504-2, and the intermediate filter body fixing protrusion 504-2 is provided with a screw hole matching with the upper shell connecting stud 603-1, so as to realize the structure of the base and the upper shell being connected by screws, and the intermediate filter body 3 installed in the inner cavity enclosed by the first annular upper protrusion 504 performs the first purification treatment operation on the air.

The intermediate carrier 303 is a cylindrical body with an opening at the bottom. A plurality of connecting plates 304 are arranged between the intermediate carrier and the filter box body. The connecting plates can not only play a structural connection role but also effectively guide the wind. A closed end plate 305 is installed on the top of the intermediate carrier. The closed end plate allows the incoming wind to enter the filter body from the air duct surrounding the outside of the intermediate carrier for filtration. A suspended annular plate 306 is circumferentially installed on the outside of the filter box body. The suspended annular plate is connected and installed to the filter box body 301 through three Z-shaped metal connectors 306-1. A filter body 307 located at the lower part of the connecting plate is installed in the gap between the intermediate carrier and the filter box body. The filter body includes but is not limited to a filter sponge.
