Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations or positional relationships based on those shown in the drawings, merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.

Example 1

Referring to fig. 1-3, the present embodiment provides a technical solution:

the utility model provides a high-efficient air cleaner of HEPA, includes HEPA filter body 1, and 1 internally mounted of HEPA filter body has filter screen 11, is provided with protection network 2 on HEPA filter body 1's the preceding lateral wall, and still is provided with surface dust clearance mechanism 3 on HEPA filter body 1, and surface dust clearance mechanism 3 comprises cleaning component 31 and dust absorption component 32.

In the above scheme, the cleaning assembly 31 includes a pair of sliding rods 311 fixed on left and right side walls of the HEPA high efficiency air filter, a sliding sleeve 312 is connected on the sliding rods 311 in a sliding manner, a connecting rod 3121 is fixed on a front side wall of the sliding sleeve 312, a mounting plate 313 is fixed at front ends of the two connecting rods 3121, a cleaning brush 314 is fixed on a rear side wall of the mounting plate 313 through screws, and the cleaning brush 314 corresponds to the filter screen 11. When the surface of the filter screen 11 is stained with a small amount of dust and the normal circulation of air is affected, in order to avoid the complicated disassembling work, only the mounting plate 313 needs to be pulled up and down, the cleaning brush 314 is driven to move up and down under the action of the sliding sleeve 312 and the sliding rod 311, and in the process of moving up and down, a small amount of dust accumulated on the outer surface of the filter screen 11 can be cleaned down.

As a preference of this embodiment, a stopper 3111 is fixed to the bottom of the slide bar 311. In order to prevent the sliding sleeve 312 from being separated from the sliding rod 311 due to the fact that the mounting plate 313 is pulled up and down to be too hard, the limiting block 3111 is used for limiting the sliding sleeve 312, and the structural stability of the device is ensured.

Preferably, the dust collection assembly 32 includes a dust box 321 disposed outside the HEPA filter body 1, a dust collector 322 is mounted on the top of the dust box 321, a dust discharge pipe 3221 is communicated with an air outlet of the dust collector 322, the dust discharge pipe 3221 is communicated with the inside of the dust box 321, an air inlet of the dust collector 322 is communicated with a dust collection pipe 3222, an installation pipe 323 is communicated with one end of the dust collection pipe 3222 far away from the dust collector 322, a plurality of hoses 324 are communicated with the installation pipe 323, a dust collection bucket 325 is communicated with one end of the hoses 324 far away from the installation pipe 323, the dust collection bucket 325 is installed on the bottom wall of the installation plate 313, and the dust collection buckets 325 face the filter screen 11. When the cleaning brush 314 brushes down the dust, owing to receive the external force effect, tiny dust particle enters into HEPA filter body 1's inside very easily, and the dust can be brushed away simultaneously, leads to flying everywhere, provides power through dust catcher 322, and a plurality of dust hoppers 325 follow cleaning brush 314 and reciprocate, when the dust was brushed down, just can produce the suction towards the outside for the dust is fought 325 through the dust and is entered into in the dust case 321 at last, makes things convenient for the processing of follow-up dust.

Preferably, the diameter of the hose 324 is smaller than that of the dust suction pipe 3222. In order to ensure a continuous and strong suction force for dust, the plurality of hoses 324 branch off the airflow of the dust suction pipe 3222, but the flow speed of the airflow is faster due to the small pipe diameter, and the suction force is ensured.

In the specific use process, the dust collector 322 is opened, the dust collector 322 works to generate negative pressure, then the mounting plate 313 is pulled up and down, the cleaning brush 314 is driven to move up and down under the action of the sliding sleeve 312 and the sliding rod 311, dust accumulated on the outer surface of the filter screen 11 is brushed off, and meanwhile scattered dust is sucked into the dust box 321 from the dust collection hopper 325.

Example 2

Referring to fig. 4-5, the present embodiment provides the following technical solutions based on embodiment 1: still be provided with locking Assembly on HEPA filter body 1 and the protection network 2, locking Assembly includes a pair of cardboard 12, has seted up the draw-in groove on the cardboard 12, is fixed with the frame on the protection network 2, and the draw-in groove is corresponding with the frame bottom.

Preferably, the locking assembly further includes a pair of rotating shafts 13 rotating with the front side wall of the HEPA filter body 1, a rotating plate 131 is fixed at the front end of the rotating shaft 13, a limiting bolt 132 is embedded on the rotating plate 131, the outer frame is provided with an inserting hole 21, and the front side wall of the HEPA filter body 1 is provided with an inserting groove corresponding to the inserting hole 21. In the actual dust cleaning process, in order to improve the efficiency, the protection net 2 must be detached, and in order to improve the detachment efficiency, only the restriction bolt 132 needs to be pulled out from the insertion hole 21 and the insertion groove, and then the rotation plate 131 is rotated under the action of the rotation shaft 13, so that the protection net 2 and the outer frame can be directly taken out together.

In a specific using process, the limiting bolt 132 is pulled out from the jack 21 and the slot, then the rotating plate 131 is rotated under the action of the rotating shaft 13, and the outer frame is lifted upwards, so that a dust cleaning process can be performed.
