It is preferred that the motor 42 is connected to the air guide blade in the middle position, so that the torque between the linkage rod 43 and other air guide blades is symmetrical, so that the swing of the air guide blade 41 is more stable and it is not easy to produce mechanical abnormal noise; in the off state, the air guide blade 41 covers the air outlet 110; the interior of the fuselage 1 is divided into an upper and a lower space by a bracket 19, and the blowing mechanism 2 is arranged in the upper space of the fuselage, and the blowing mechanism 2 is carried on the bracket 19, and the air inlet of the blowing mechanism 2 is opposite to the air inlet grid 191 on the bracket 19, and the filter group 3 is arranged in the lower space of the fuselage;

[0027] See attached Figure 2 and 6 The filter group 3 includes a cylindrical filter 31 and a plurality of plate filters 32 located beside the cylindrical filter 31. A central embedding position 101 for embedding the cylindrical filter 31 is provided in the lower space of the fuselage. A plurality of side slots 102 for inserting the plate filters 32 are provided on both sides of the central embedding position 101. These side slots 102 are separated by a plurality of partitions 103 provided on the bottom plate 17 and the bracket 19 and are parallel to each other so that the plate filters 32 can be inserted side by side. The right side plate 15 and the right side plate 16 are respectively provided with ventilation holes, which are opposite to the side-by-side plate-shaped filters 32. The central channel of the cylindrical filter 31 is opposite to the air inlet grille 191 on the bracket 19.

This also avoids the power supply device 5 and power board 6 occupying the internal space of the fuselage 1 and causing a mess in the power harness, thereby optimizing the internal layout of the fuselage 1.

[0029] See attached Figure 2 , 3 6, the baffle 14 is arranged at the lower part of the back side of the fuselage 1, and after removing the baffle 14, the lower space of the fuselage accommodating the filter group 3 is exposed, the lower end of the baffle 14 is provided with a claw 141, and the upper end thereof is provided with a magnetic block 142 for adsorbing and fixing with the fuselage 1, and the bottom of the fuselage is provided with a slot 104 for the claw 141 to be embedded, the claw 141 is embedded in the slot 104 and the upper end of the baffle 14 is flipped toward the fuselage 1 with the claw 141 as a fulcrum until the magnetic block 142 is adsorbed and fixed with the fuselage 1, and the fuselage 1 can be provided with screws or iron sheets to realize the adsorption of the magnetic block 142. This structure is convenient for users to disassemble and assemble the baffle, and then remove the filters one by one for cleaning or replacement.

[0030] Furthermore, a force-applying portion 143 for applying force and pulling is provided at the upper end of the baffle 14. The force-applying portion 143 is a groove formed in a depression on the baffle 14. The user only needs to extend a finger into the groove and apply force and pull outward to easily separate the upper end of the baffle 14 from the fuselage 1, thereby allowing the baffle 14 to be flipped and pulled out.

[0031] Furthermore, in order to prevent the baffle 14 from being loosened and having a gap between the baffle 14 and the body 1 after being covered, a locking block 144 is provided at the lower end of the baffle 14, and a locking hole 173 for inserting the locking block 144 is provided on the bottom plate 17 of the body 1. The locking hole 173 is staggered with the card slot 104. Figure 6 As the baffle 14 flips toward the fuselage 1, the locking block 144 is gradually inserted into the locking hole 173.

This inclined surface design, on the one hand, does not form a vertical gap when the air guide blades 41 are connected, and it is not easy for dust or foreign matter to enter. On the other hand, the inclined surface can also facilitate the flow when the air is discharged.

[0033] For further information, see Appendix Fig.10 The top of the fuselage 1 is provided with a plurality of columns 7, the top of each column 7 has a supporting platform 71 for supporting the air outlet bracket 100, and a supporting branch 72 for supporting the top cover 11; see the attached Fig. 9 The side of the air outlet bracket 100 is provided with a support ear 1003 that cooperates with the supporting platform 71. Since the air outlet 110 is opened in the middle of the top cover 11, its annular top surface 111 is easily deformed by force, especially when a heavy object is placed on the air purifier, it is easy to bend the annular top surface 111 of the top cover, so the top cover 11 is supported to a certain extent by the support branch 72.

[0034] Furthermore, an atmosphere indicator light 8 for indicating the air quality is provided on the front of the body 1. The control panel detects the current air quality data through devices such as dust sensors or odor sensors 9, and then indicates it through lights of different colors and different breathing frequencies of the atmosphere indicator light 8 according to the settings, so that the user can understand the air quality of the current space more intuitively.

[0035] The above-mentioned preferred implementation modes should be regarded as illustrative examples of the implementation modes of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on this scheme should be regarded as within the scope of protection of this patent.
