[0036] A purification module is arranged in the purifier body 1, and a fan for accelerating the flow of gas is arranged above the purification module.

[0037] It also includes a filter screen 3. A plurality of filter screens 3 are arranged outside the purifier body 1. The filter screen 3 is used to filter the air entering the purifier body 1 and intercept larger dust particles in the air.

[0038] A mounting frame 4, to which the filter screen 3 is fixedly connected on both upper and lower sides, and the cross section of the mounting frame 4 is a C-shaped structure;

[0039] Fixed plates 5, a plurality of fixed plates 5 are fixedly connected to the outer side of the purifier body 1, and the number of the fixed plates 5 is the same as the number of the sliding wheels 2;

[0040] A magnet block 6 is provided on a side of the fixing plate 5 away from the purifier body 1 , and the magnet block 6 is magnetically connected to the inner side of the mounting frame 4 .

[0041] The material inside the installation frame 4 is metal material, and the metal material can be magnetically attracted.

[0042] An annular sealing strip 7 is connected to the edge of the filter screen 3 close to the purifier body 1 , and the annular sealing strip 7 ensures that there is no gap between the side of the filter screen 3 and the outer wall of the purifier body 1 .

[0043] A limiting assembly 8 is arranged above the mounting frame 4 located above, and the limiting assembly 8 limits the position of the upper mounting frame 4; the limiting assembly 8 includes a fixed shell 81, a spring 82, a connecting column 83 and a limiting frame 84, the fixed shell 81 is arranged above the mounting frame 4, the inner wall of the top surface of the fixed shell 81 is fixedly connected with a spring 82, the lower end of the spring 82 is fixedly connected to the top of the connecting column 83, the bottom end of the connecting column 83 is fixedly connected to the limiting frame 84, and the limiting frame 84 is arranged on the outside of the mounting frame 4 located on the upper side; a plurality of fixed shells 81 are fixedly connected to the outside of the purifier body 1, and the number of the fixed shells 81 is the same as the number of the filter screens 3; the cross-section of the connecting column 83 is a T-shaped structure, and the cross-section of the limiting frame 84 is an inverted L-shaped structure.

[0044] When installing the filter 3, the mounting frame 4 is magnetically connected to the magnet block 6. At this time, under the action of the spring 82, the connecting column 83 and the limit frame 84 move downward, so that the limit frame 84 moves to the outside of the upper mounting frame 4, limiting the mounting frame 4 to prevent the filter 3 from being moved by mistake.

[0045] A motor 9 is installed above the purifier body 1, and the output end of the motor 9 is fixedly connected to an air guide plate 10. A plurality of shielding plates 11 distributed in a circular array are arranged below the air guide plate 10. A fixing column 12 is fixedly connected to the top of the shielding plate 11, and the top of the fixing column 12 is fixedly connected to the bottom of the air guide plate 10.

[0046] When the air purifier is in operation, the shielding plate 11 is not directly above the air outlet. At this time, the purified air is discharged from the purifier body 1 through the air outlet. When the air purifier is not in use, the motor 9 is used to rotate the air guide plate 10, thereby driving the fixed column 12 to rotate, and then driving the shielding plate 11 to rotate, so that the shielding plate 11 covers the air outlet to prevent dust from entering the purifier body 1 from the air outlet.

[0047] The motor 9 is electrically connected to the switch of the purifier body 1, that is, when the switch of the purifier body 1 is pressed to start, the motor 9 starts to drive the baffle 11 to rotate, exposing the air outlet, and then the motor 9 stops running. At this time, the purifier body 1 continues to run. When the switch of the purifier body 1 is pressed to turn off, the motor 9 starts to drive the baffle 11 to rotate. When the baffle 11 covers the air outlet, the motor 9 stops running.

[0048] A plurality of rolling wheels 13 are installed at the bottom of the shielding plate 11, and a sliding groove is opened on the top surface of the purifier body 1. The rolling wheels 13 roll in the sliding groove as the shielding plate 11 rotates. The rolling wheels 13 can make the shielding plate 11 slide more smoothly.

[0049] The top of the shielding plate 11 is connected to the wind guide plate 10 through at least one fixing column 12. The cross section of the wind guide plate 10 is an arc-shaped structure, and the wind guide plate 10 can guide the outgoing air.

[0050] When the present application is in use, the electrical components appearing in the present application are all externally connected to a power source and a control switch. The sliding wheel 2 can be used to facilitate the movement of the air purifier during use. When the air purifier is in operation, preliminary filtration is performed through the filter 3, and then the purification module in the purifier body 1 is used for purification, and the air is discharged from the top surface of the purifier body 1. When the filter 3 is blocked, the connecting column 83 and the limit frame 84 are first moved upward. At this time, the filter 3 is directly moved away from the purifier body 1. At this time, the filter 3 drives the mounting frame 4 away from the magnet block 6, destroying the magnetic attraction between the mounting frame 4 and the magnet block 6, and the filter 3 can be removed. At this time, the removed filter 3 can be thoroughly and comprehensively cleaned.

[0051] The benefits of this application are:

[0052] 1. The present invention is easy to disassemble and assemble. The filter is integrally arranged outside the purifier body, and the filter can be quickly disassembled and assembled by the magnetic attraction between the mounting frame and the magnet block, so that the filter can be thoroughly and comprehensively cleaned. Moreover, multiple filters can be disassembled and assembled separately, and the clogged filter can be disassembled and assembled and cleaned in a targeted manner.

[0053] 2. The present application has a reasonable structure, and a motor can be used to drive the shielding plate to rotate, so that the air outlet can be shielded when the air purifier is not in operation, thereby preventing dust from entering the purifier body through the air outlet.

[0054] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software and methods.
