[0006] By adopting the above technical solution, after the installation frame and the partition frame are combined, the installation frame can be inserted into the interior of the fan body, so that the inclined block and the inclined surface of the inclined top block are fitted together, and the inclined top block is squeezed into the interior of the fan body. After the inclined block passes, the inclined top block pops out from the fan body and engages with the inclined block and the sliding rod. By pulling the partition frame and cooperating with the support of the block on the installation frame, the installation frame is fixed inside the fan body. When installing the filter, you only need to push the installation frame into the fan body to fix it. At the same time, when taking it out, you only need to pull the elastic pull rod to remove the installation frame, which facilitates the installation of the filter.

[0007] Preferably, a spring is fixedly mounted at one end of the fan body close to the mounting frame, and the other end of the spring is in contact with the outer surface of the tilting block.

[0008] By adopting the above technical solution, when the elastic pull rod is pulled, the inclined top block will disengage from the tilting block, and the spring will apply thrust to the tilting block and the sliding rod to push the partition frame out and separate it from the installation frame, making it convenient to hold the partition frame and take out the installation frame.

[0009] Preferably, a partition grid is provided inside the installation frame, and the partition grid is designed as a square grid, the outer surface of the partition grid is in contact with the outer surface of the partition net, and the interior of the partition grid is filled with activated carbon particles.

[0010] By adopting the above technical solution, activated carbon particles can be put into the partition grid in the installation frame, and harmful gases in the air can be adsorbed by the activated carbon particles.

[0011] Preferably, a sliding plug-in mechanism is provided inside the installation frame and the partition frame, which facilitates the replacement of the filter element and prevents gas from entering the fan body through the gap.

[0012] By adopting the above technical solution, when the filter cotton core needs to be replaced, it is necessary to pull the elastic pull rod to disengage the inclined top block from the inclined block, then take the installation frame out of the fan body and put the installation frame horizontally down to pull out the insertion frame, and remove the filter cotton core in the insertion frame for replacement.

[0013] Preferably, the sliding plug-in mechanism includes: an insertion frame, a filter cotton core is installed in the interior of the insertion frame, and the side surface of the filter cotton core is fitted with the outer surface of the insertion frame, a sealing ring is fixedly installed on the side of the insertion frame close to the installation frame, and the outer surface of the sealing ring is fitted with the outer surface of the installation frame, and a partition net is fixedly installed on the outer surface of one end of the insertion frame away from the sealing ring.

[0014] By adopting the above technical solution, when the insertion frame is inserted into the interior of the installation frame and the partition frame, the activated carbon particles in the partition grid can be effectively blocked by the filter cotton core in the insertion frame, so that the activated carbon is confined inside the partition grid. When the insertion frame is taken out, the activated carbon particles can be poured out, which is convenient for replacing the activated carbon particles, and the partition net can also be cleaned at the same time.

[0016] By adopting the above technical solution, the position of the insertion frame can be restricted within the installation frame through the engagement of the plug-in block and the installation frame. At the same time, when the installation frame is fixed inside the fan body, the groove will engage with the plug-in block, so that the insertion frame is fixed in the installation frame. When the installation frame is inserted into the fan body, the insertion frame cannot be directly pulled out, reducing the probability of leakage of activated carbon particles due to gaps in the insertion frame due to vibration.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the filter for the purification fan which is easy to install and clean:

[0018] 1. When installing the installation frame, you need to first pour the activated carbon into the interior of the partition grid, then directly insert the insertion frame with the filter cotton core into the installation frame, and then directly pick up the installation frame and insert it into the interior of the fan body, so that the tilting block can directly push the inclined top block, so that the installation frame fits with the block, and the tilting block and the inclined top block are engaged, so that the partition frame is close to the installation frame, and the installation frame is fixed in the fan body. When installing, you only need to directly push the installation frame into the fan body to fix it, reducing the problem of carrying tools for disassembly and assembly and the easy falling of parts;

[0019] 2. When the filter needs to be cleaned, just pull the elastic pull rods on both sides of the fan body to disengage the inclined top block from the inclined block. Then the spring will release the force generated by the compression, push the inclined block out and drive the sliding rod to push out a part of the way, so that the partition frame is pushed out. It is convenient to grab the partition frame and pull the installation frame out of the fan body. Then you can clean the partition and replace the filter cotton core and activated carbon particles.

[0020] 3. When replacing activated carbon particles, the installation frame needs to be laid flat so that the partition grid is level with the ground. Then, the activated carbon particles can be poured in to fill the interior of the partition grid with activated carbon. Then, the insertion frame with the replaced filter cotton core can be inserted into the installation frame. Then, the installation frame is lifted and inserted back into the fan body for fixation. By engaging the tilting block and the inclined top block, the groove on the outer surface of the sliding rod engages with the insertion block, and the insertion frame is fixed inside the installation frame. The installation frame cannot be pulled out when it is inside the fan body, thereby preventing leakage of activated carbon caused by vibration and displacement of the insertion frame.

[0030] When installing the filter, you only need to directly pick up the installation frame 2 and insert the installation frame 2 into the fan body 1, so that the tilting block 5 can push the tilting top block 14 away, and the tilting top block 14 can be retracted into the fan body 1. Then the installation frame 2 is fitted with the stop block 16, and the elastic pull rod 13 pushes the tilting top block 14 back, so that the tilting top block 14 can be respectively engaged with the sliding rod 4 and the tilting block 5, and the partition frame 8 cooperates with the stop block 16 to squeeze and fix the installation frame 2. The filter can be quickly installed on the side surface of the fan body 1 without using any tools.

[0031] The sliding engagement device includes: an elastic pull rod 13, which is slidably installed on the outer surfaces of both sides of the fan body 1, and a slanted top block 14 is slidably installed inside the fan body 1, and the slanted top block 14 is connected to one end of the elastic pull rod 13, a stop block 16 is fixedly installed inside the fan body 1, and the outer surface of the stop block 16 is in contact with the outer surface of the mounting frame 2, and a tilted block 5 is fixedly installed at one end of the sliding rod 4 located inside the fan body 1, and the outer surface of the tilted block 5 is engaged with the outer surface of the tilted top block 14, and the outer surface of the tilted top block 14 is in contact with the outer surface of the sliding rod 4, the outer surface of the tilted block 5 is designed to be inclined, and the side surface of the tilted top block 14 is designed to be inclined.

[0032] When the filter needs to be disassembled, the elastic pull rods 13 on both sides can be directly pulled to disengage the inclined top block 14 from the inclined block 5 , and then the partition frame 8 can be held to take the installation frame 2 out of the fan body 1 .

[0033] A spring 15 is fixedly mounted at one end of the fan body 1 close to the mounting frame 2 , and the other end of the spring 15 is in contact with the outer surface of the tilting block 5 .

[0034] The tilting block 5 can be pushed out by the spring 15, driving the sliding rod 4 to move slightly, so that a gap is generated between the barrier frame 8 and the installation frame 2 to make it easier to grasp, so that the installation frame 2 can be removed conveniently.

[0035] The interior of the installation frame 2 is provided with a partition grid 3, and the partition grid 3 is designed as a square grid, the outer surface of the partition grid 3 is in contact with the outer surface of the partition net 7, and the interior of the partition grid 3 is filled with activated carbon particles.

[0036] The activated carbon particles can be confined inside the installation frame 2 by the partition 7 and the partition grid 3, so that the activated carbon particles cannot escape after the insertion frame 9 is inserted. At the same time, the external air can pass through the activated carbon particles and the partition 7 to absorb harmful substances in the air.

[0037] A sliding plug-in mechanism is provided inside the installation frame 2 and the baffle frame 8, which facilitates the replacement of the filter element and prevents gas from entering the fan body 1 through the gap.

[0039] The sliding plug-in mechanism includes: an insertion frame 9, a filter cotton core 12 is installed in the interior of the insertion frame 9, and the side surface of the filter cotton core 12 is in contact with the outer surface of the insertion frame 9, a sealing ring 11 is fixedly installed on the side of the insertion frame 9 close to the installation frame 2, and the outer surface of the sealing ring 11 is in contact with the outer surface of the installation frame 2, and a partition net 7 is fixedly installed on the outer surface of the end of the insertion frame 9 away from the sealing ring 11.

[0040] The filter cotton core 12 can intercept dust particles in the external air. At the same time, the filter cotton core 12 can be replaced when it is too dirty and clogged. When replacing the filter cotton core 12, you only need to take out the installation frame 2 and place it horizontally to prevent the activated carbon particles from spilling after opening. Then, pull out the insertion frame 9, remove the filter cotton core 12 in the insertion frame 9 for replacement, and then insert the insertion frame 9 back and insert the installation frame 2 back into the fan body 1.

[0041] Insert blocks 10 are fixedly installed on the outer surfaces of both sides of the installation frame 2, and the insert blocks 10 are inserted into the interior of the installation frame 2.
