[0021] The suction air pump 5 draws the outside air into the interior of the purifier housing 3 through the air intake pipe 8. The protective net 7 prevents large impurities and flying insects from entering. The air then passes through the first filter layer 144 and the second filter layer 145 to filter out dust particles. The locking assembly 15, the limit block 16 and the unlocking mechanism 17 facilitate the disassembly of the filter assembly 14. Finally, the air passes through the photocatalyst purification assembly to purify the harmful components therein and discharge them to the outside, completing the purification process.

[0022] Slide grooves 143 are disposed on both sides of the outer frame 141 , and the outer frame 141 is slidably connected to the sliding track 13 via the slide grooves 143 . The other end of the outer frame 141 is an external end 142 .

[0023] The slide groove 143 is slidably connected to the slide rail 13 to prevent the outer frame 141 from being skewed when inserted. When disassembling, the outer end 142 can be pulled after the unlocking mechanism 17 is unlocked.

[0024] A universal wheel 2 is disposed at the lower portion of the bottom plate 1 , and a temperature detection module 11 and a humidity detection module 12 are disposed on the mounting plate 4 .

[0027] The limiting block 16 is used to insert the locking assembly 15 so that the outer frame 141 is more stable after installation.

[0028] The locking assembly 15 includes a baffle 151, a fixing block 152 and a spring 154. The fixing block 152 is fixedly connected to the outer frame 141.

When the locking block 155 moves to the limiting groove 162, since the inclined surface 163 no longer squeezes the locking block 155 at this time, the telescopic rod 153 and the spring 154 are restored, and the locking block 155 is pressed into the limiting groove 162, and the positioning rod 164 is inserted into the positioning hole 156 to complete the locking.

[0030] The unlocking mechanism 17 includes a rotating wheel 171 and a rotating rod 172 , the rotating rod 172 is rotatably connected to the purifier housing 3 , a threaded sleeve 173 is provided at the end of the rotating rod 172 , a pushing block 174 is threadedly connected to the threaded sleeve 173 , and the shape of the pushing block 174 corresponds to the locking block 155 .

[0032] The photocatalyst purification component includes an ultraviolet lamp group 18, which is fixedly connected to the inner wall of the purifier housing 3, and a photocatalyst purification plate 19 is fixedly connected to the inner wall of the purifier housing 3. The bottom of the purifier housing 3 is provided with multiple groups of evenly distributed diversion air inlets 20, and the outside of the purifier housing 3 is provided with an exhaust part 21, and the exhaust part 21 is connected to the diversion air inlet 20.

[0033] Under the action of the photocatalyst purification plate 19 irradiated by the ultraviolet lamp group 18, harmful components in the air are purified, and multiple groups of evenly distributed diversion air inlets 20 make the flow process of air discharge more uniform.

[0034] The principle of the utility model is as follows: the suction air pump 5 draws the outside air into the interior of the purifier housing 3 through the air intake pipe 8, the protective net 7 prevents large impurities and flying insects from entering, and then passes through the first filter layer 144 and the second filter layer 145 to filter out dust particles, the locking component 15, the limit block 16 and the unlocking mechanism 17 facilitate the disassembly of the filter component 14, and finally the air passes through the photocatalyst purification component to purify the harmful components therein and discharge them to the outside, completing the purification process.
