[0001] The utility model relates to the technical field of air purification equipment, in particular to an air purification equipment which is convenient to disassemble. Background Technique

[0002] The air purification box type fan is an effective air purification equipment, which can make the indoor air circulate. On the one hand, it sucks the outdoor turbid air into the purification box, and then filters the air through the filter screen inside the fresh air purification box. On the other hand, it inputs the filtered air into the room again, so that the room can maintain healthy fresh air.

[0003] Most of the existing air purification box type fans are connected to the pipeline by fish tail screws around the pipeline and the periphery of the purification box. The number of fish tail screws at the connection is large, and some of the fish tail screws are located at the lower edge of the purification box. The installation of the fish tail screws at this part is extremely inconvenient due to the shielding of the purification box. This also leads to the inconvenience of disassembling the fish tail screws when disassembling and repairing the air purification box type fan, which greatly affects the maintenance efficiency of the air purification box type fan. Based on this, an air purification equipment which is convenient to disassemble is provided. Content of the Utility Model

[0011] The four L-shaped crimping plates are located outside the rectangular docking frame and are respectively in the middle of the two square housing covers. The rotating shaft is fixed at one end of the L-shaped crimping plate, and both ends of the rotating shaft extend to the inside of the square housing cover. The linkage bevel gears are symmetrically fixed at the two ends of the rotating shaft, and the two linkage bevel gears on the two adjacent and vertically distributed rotating shafts are meshed with each other;

[0012] The synchronous rotation of the four rotating shafts and the L-shaped crimping plates is realized through four groups of mutually meshed linkage bevel gears. The four L-shaped crimping plates rotate synchronously and approach the rectangular splicing fold edge to realize the fitting and pressing of the four edges of the external square air duct and the rectangular splicing fold edge.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, an air purification device that is easy to disassemble includes a purification box 1 composed of a box body 101, a rectangular docking frame 102, and a rectangular splicing folded edge 103. The rectangular docking frames 102 are symmetrically fixed at both ends of the box body 101, and the rectangular splicing folded edge 103 is fixed at one end of the rectangular docking frame 102 away from the box body 101. A quick-installation component 2 is arranged on the outer side of the rectangular docking frame 102, and the quick-installation component 2 is used to realize the convenient fixation of the rectangular splicing folded edge 103 and an external square air duct;

[0028] The quick-installation component 2 includes a linkage clamping unit and a locking unit;

[0029] The linkage clamping unit is used to realize the fitting and pressing operation of the four edges of the external square air duct and the rectangular splicing folded edge 103;

[0030] The locking unit is used to realize the locking operation of the linkage clamping unit;

[0031] The clamping unit includes a square shell cover 201, an L-shaped crimping plate 202, a rotating shaft 203, and a linkage bevel gear 204;

[0032] There are four square housings 201 and L-shaped crimping plates 202. The four square housings 201 are respectively fixed to the four corner edges of the rectangular docking frame 102 and close to one end of the rectangular splicing fold 103.

[0033] The four L-shaped crimping plates 202 are located outside the rectangular docking frame 102 and respectively in the middle of two square housings 201. The rotating shaft 203 is fixed to one end of the L-shaped crimping plate 202, and both ends of the rotating shaft 203 extend to the inside of the square housing 201. The linkage bevel gears 204 are symmetrically fixed to the two ends of the rotating shaft 203, and the two linkage bevel gears 204 on two adjacent and vertically distributed rotating shafts 203 are meshed with each other.

[0034] The synchronous rotation of the four rotating shafts 203 and L-shaped crimping plates 202 is realized through four groups of mutually meshing linkage bevel gears 204. The synchronous rotation of the four L-shaped crimping plates 202 close to the rectangular splicing fold 103 realizes the fitting and pressing of the four edges of the external square air duct with the rectangular splicing fold 103.

[0035] The locking unit includes a rotating block 205, an arc-shaped locking groove 206, and a fish-tail screw 207.

[0036] One end of the linkage bevel gear 204 connected to the rotating shaft 203 distributed at the upper and lower ends of the rectangular docking frame 102 is fixedly connected with a connecting shaft extending to the outside of the square housing 201. The rotating block 205 is fixed to one end of the connecting shaft and fits against the outside of the square housing 201.

[0037] The arc-shaped locking groove 206 is opened on the end face of the rotating block 205. The screw part of the fish-tail screw 207 is inserted into the inside of the arc-shaped locking groove 206 and screwed tightly with the square housing 201 to realize the locking of the rotating block 205, and then realize the locking of the linkage bevel gear 204.

[0038] In this embodiment, it should be supplemented and explained that: a fan, a coarse filter screen, and a fine filter screen are installed inside the box body 101. The indoor air can be sucked into the box body 101 through the suction generated by the fan, and the air passing through the inside of the box body 101 can be filtered by the coarse filter screen and the fine filter screen. The filtered air is then delivered to the indoor, thus realizing the cyclic purification of the indoor air.

[0039] When installing the purification box 1 and the square ventilation duct, the operation steps are as follows:

[0040] After installing the square ventilation duct for sucking indoor air, the air inlet of the box body 101 can be oriented towards the square ventilation duct and moved closer. Finally, the rectangular splicing fold 103 at the air inlet of the box body 101 is in contact with the four folded edges of the square ventilation duct (it should be noted that: a sealing strip can be pasted on the end face of the rectangular splicing fold 103 to achieve sealing).

[0041] After rotating an L-shaped crimping plate 202 to make the L-shaped crimping plate 202 rotate closer to the rectangular splicing fold 103, at this time, through the transmission of four groups of meshing linkage bevel gears 204, the other three L-shaped crimping plates 202 can also rotate synchronously. In this way, the synchronous flipping of the four L-shaped crimping plates 202 can be realized. Finally, the folded edge parts of the four L-shaped crimping plates 202 are closely attached to the four folded edge edges of the square ventilation pipe, so that the folded edge edges of the square ventilation pipe are closely attached to the end face of the rectangular splicing fold 103. After that, the fish-tail screw 207 is inserted into an arc-shaped locking groove 206 of the rotating block 205 and drilled into the outer housing 201 to realize the tightening with the outer housing 201. The top cap of the fish-tail screw 207 is pressed and attached to the side of the rotating block 205, and then the rotating locking groove of the linkage bevel gear 204 is realized, so that the four L-shaped crimping plates 202 are fixed in this state, and then the installation and fixation of the purification box 1 and the square ventilation pipe are completed;

[0042] After that, connect the square ventilation pipe for exhausting indoor air with the air outlet of the box body 101, and the operation steps are the same as above;

[0043] When the purification box 1 needs to be disassembled, only the fish-tail screw 207 needs to be disassembled, and then the L-shaped crimping plate 202 can be rotated and opened. Compared with the traditional structure in which a large number of fish-tail screws 207 are tightened along the four-week edge of the square ventilation pipe, the fish-tail screws 207 distributed on the outside of the square housing 201 not only have a small number, but also are not blocked by the purification box 1. It is not only convenient for disassembly and assembly, but also has less overall workload, can effectively improve the disassembly and assembly efficiency of the purification box 1, and is convenient for later maintenance and replacement.

[0044] Please refer to Figures 1 to 3 , a plurality of arc-shaped locking grooves 206 are provided, and the plurality of arc-shaped locking grooves 206 are evenly distributed in a ring on the circumferential end face of the rotating block 205.

[0045] In this embodiment: through this structure, one or more fish-tail screws 207 can be installed on one rotating block 205, which not only ensures the stable fastening of the equipment, but also makes the overall installation operation more flexible.

[0046] Please refer to Figures 1 to 4 , when the L-shaped crimping plate 202 rotates to the horizontal transverse part and fits against the side of the rectangular splicing fold 103, the distance between the folded edge part of the L-shaped crimping plate 202 and the end face of the rectangular splicing fold 103 matches the thickness of the four edges of the external square air duct;

[0047] The distance between the rectangular splicing fold 103 and the box body 101 is greater than the diameter of the rotation trajectory of the L-shaped crimping plate 202.

[0048] In this embodiment: Through this structure, the rotatable angle of the L-shaped crimping plate 202 is greater than 180 degrees. That is, when the L-shaped crimping plate 202 rotates and opens, the folded edge portion of the L-shaped crimping plate 202 is far from the rectangular splicing folded edge 103, and it will not interfere with the separation of the rectangular splicing folded edge 103 from the folded edge of the square ventilation pipe.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
