[0031] like Figure 1-7 As shown, the utility model provides an air intake structure of a cabinet-type air purification device, including an air intake port 2 arranged on the cabinet-type air purification device 1, and also including:

[0032] The air intake mechanism 3 includes an air intake mesh plate 31 arranged on the outside of the air inlet 2 and a movable mesh plate 32 superimposed on the inside of the air intake mesh plate 31, which is used to adjust the air intake amount of the cabinet air purification device 1;

[0033] The cleaning mechanism 4 is flipped and arranged on the front side of the cabinet air purification device 1, and is used to clean and maintain the particulate impurities remaining on the mesh holes of the air intake mesh plate 31 and the movable mesh plate 32. With this design, the air intake mechanism 3 is arranged at the air inlet 2 of the cabinet air purification device 1. Since the movable mesh plate 32 included in the air intake mechanism 3 can move horizontally in the air intake mesh plate 31, the mesh holes of the air intake mesh plate 31 can be adjusted under the misalignment and shielding of the plate surface without mesh holes on the movable mesh plate 32, thereby realizing the mesh size adjustment function. The cleaning mechanism 4 is also arranged on the front side of the cabinet air purification device 1, which can negatively suck the particulate impurities under cleaning, effectively collect them, and effectively reduce the adhesion of particulate impurities and the filtering effect of the filter element structure that enters the interior of the device with the air flow and affects them.

[0034] In one embodiment, the air intake mechanism 3 further includes a moving block 33 disposed on one side of the top of the movable mesh plate 32, and a guide cross bar 34 is disposed on the end surface of the moving block 33 for horizontal movement; the guide cross bar 34 is used to support the displacement of the moving block 33 while providing position limiting support. With this design, the moving block 33 welded on the top of the movable mesh plate 32 and the through slots horizontally penetrating the moving block 33 move horizontally under relative movement on the guide cross bar 34, thereby realizing the function of horizontal movement of the movable mesh plate 32 in the air intake mesh plate 31, thereby realizing the function of adjusting the size of the mesh holes on the air intake mesh plate 31, and achieving the effect of adjustable air intake volume.

[0035] In one embodiment, an operating handle is provided on the moving block 33, and the operating handle is provided through a corner end of the air inlet mesh plate 31. With this design, by welding the operating handle on the connecting column on the moving block 33, which is perpendicular to the center line of the moving block 33 and is welded to the side of the moving block 33 and penetrates the opening on the air inlet mesh plate 31, the operating handle can be used on the outside of the air inlet mesh plate 31 to drive the movement of the movable mesh plate 32, which is convenient for operation.

[0036] In one embodiment, the cleaning mechanism 4 includes a cabinet door 41 disposed on the cabinet air purification device 1, and the inner surface of the cabinet door 41 is provided with a cleaning component 42 for cleaning particulate impurities remaining on the mesh holes of the air inlet mesh plate 31 and the movable mesh plate 32. With this design, the cabinet door 41, which is hinged and flipped using a hinge on the front side of the cabinet air purification device 1, can be closed in normal use and opened during inspection and maintenance. In addition, the cleaning component 42 designed in the cabinet door 41 can scrape off the particulate impurities remaining on the edge of the mesh hole in an up and down reciprocating manner, and at the same time, use the negative pressure of the airflow to absorb and collect them, so as to effectively collect them.

[0037] In one embodiment, the cleaning assembly 42 includes a horizontal frame 4211, a plurality of suction heads 4212 evenly arranged on the horizontal frame 4211, and bristles 4213 are arranged on the horizontal frame 4211 corresponding to the mesh positions on the air inlet mesh plate 31. With this design, by distributing a plurality of suction heads 4212 at the same spacing near the surface of the air inlet mesh plate 31 on the horizontal frame 4211, and bristles 4213 corresponding to the mesh positions of a row of meshes on the air inlet mesh plate 31, particulate matter and impurities remaining on the edge of the mesh can be scraped off one by one, and suction and collection can be performed at the same time, thereby achieving cleaning and maintenance of the air inlet 2.

[0038] In one embodiment, a screw rod 4221 and a linear guide rod 4222 are respectively provided on both sides of the cross frame 4211. With this design, the screw rod 4221 rotates to drive the cross frame 4211 with threads thereon to perform vertical reciprocating motion under the limit of the linear guide rod 4222 on the other side, thereby achieving the cleaning function of the residual particulate impurities attached to the mesh holes on the surface of the air intake mesh plate 31.

[0039] It should be noted that the connection end of the screw rod 4221 is connected to a stepping motor used in conjunction with the screw rod 4221 through a coupling, which can provide power for the reciprocating motion of the screw rod 4221.

[0040] In one embodiment, a negative pressure suction pipe 423 connected to the plurality of suction heads 4212 is provided on one side of the horizontal frame 4211, and a collecting box 424 is provided at the lower end of the negative pressure suction pipe 423, and a guide plate 4241 is provided inside the collecting box 424, and a dust collecting groove 4242 is provided at the inclined lower end of the guide plate 4241; the dust collecting groove 4242 is used to gather and collect particulate impurities sucked in. With this design, through the negative pressure suction pipe 423 designed on one side of the horizontal frame 4211 and connected to the air cavity formed by multiple suction heads 4212, and the collection box 424 connected to a section of the negative pressure suction pipe 423, an air flow passage can be formed between the suction head 4212 and the collection box 424, so that the scraped particulate impurities can be collected in a concentrated manner to prevent them from escaping everywhere; in addition, the guide plate 4241 corresponding to the air inlet of the negative pressure suction pipe 423 in the collection box 424 can guide the particulate impurities entering the collection box 424 into the dust collecting trough 4242 through the inclined diversion effect for collection.

[0041] It should be noted that the end of the negative pressure suction pipe 423 after passing through the collection box 424 is connected to a small negative pressure fan that is independent of the cabinet air purification device 1 and has a power smaller than the main fan inside the cabinet air purification device 1.

[0042] It should be noted that the dust collecting trough 4242 is designed to be pull-out on one side of the collecting box 424, which is convenient for taking out the dust collecting trough 4242 for internal centralized processing. There is also a filter designed on the inner surface of the dust collecting trough 4242 relative to its outer end to prevent particulate impurities from passing through the air flow path, and a small negative pressure fan connected to the end of the negative pressure suction pipe 423 forms an air flow path for sucking the scraped particulate impurities.

[0043] In one embodiment, the cleaning mechanism 4 further includes a storage slot 43 disposed on the inner side of the cabinet door 41, and baffles 44 are disposed on both sides of the storage slot 43. In this design, by using the baffles 44 connected by sliding rails in the inner groove of the storage slot 43, the baffles 44 can be moved upward, so that the device is closed and shielded when not in use, and can also be moved downward to form a good air intake environment for use.

[0044] In one embodiment, a window for observing the cleaning and maintenance operation process at the air inlet 2 is provided on the baffle plate 44. With this design, by slotting and embedding the window in the baffle plate 44, it is possible to observe when relevant operations are performed in the area where the air inlet 2 is located, and timely intervention can be made when a problem occurs.

[0045] In one embodiment, a ventilation net 5 for forming an airflow path is provided on the back of the cabinet air purification device 1. With this design, a good air intake filtration path can be formed inside the cabinet air purification device 1 through the design of the ventilation net 5, and the use effect is good.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
