Description

Technical Field

[0001] The present invention relates to the technical field of air purification equipment, and in particular to a dual-mode air purifier. Background Art

[0002] Air purifiers are used in many fields, including homes, healthcare, and industry. Their primary function is to remove particulate matter from the air, while also addressing some organic air pollution issues. Some existing air purifiers first draw outside air into the device, then filter and purify it before discharging it. However, the internal filtration devices in some existing air purifiers are not adjustable, resulting in the use of the same purification structure and method for air in different environments. This makes the system unsuitable for a variety of air environments, resulting in reduced air quality after purification. Summary of the Invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a dual-mode air purifier, which has the advantages of being able to adjust multiple purification modes according to needs and improving applicability.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1 like Figures 1 to 7As shown, the present invention provides a dual-mode air purifier, comprising an upper box body 1; the upper box body 1 and the lower box body 2 are arranged in sequence from top to bottom, and the bottom surface of the upper box body 1 is connected to the top surface of the lower box body 2; the TiO2 photocatalytic device is arranged in the upper box body 1; the air intake component 3 is arranged below the TiO2 photocatalytic device; the intermediate filter plate component 4 is arranged at the middle position in the lower box body 2, and the intermediate filter plate component 4 divides the interior of the lower box body 2 into two parallel purification boxes 21; there are two adjusting filter plate components 5, and the two adjusting filter plate components 5 are respectively arranged in the two purification boxes 21; the air intake component 3 includes an air inlet 31 arranged on the upper box body 1, an air pump 32 arranged below the TiO2 photocatalytic device, and an air pump 32 for extracting the air. Two outlet pipes 33 are connected in parallel to the air outlet of the air pump 32, and the two outlet pipes 33 are respectively connected to the two purification boxes 21; the adjusting filter plate assembly 5 includes an adjusting filter plate frame 511 rotatably arranged in the purification box 21, and an adjusting filter plate 51 is arranged in the adjusting filter plate frame 511. The shape and size of the adjusting filter plate 51 are the same as those of the intermediate filter plate assembly 4. A main exhaust valve 52 is arranged on the side wall opposite to the intermediate filter plate assembly 4 of the purification box 21; a first auxiliary exhaust valve 53 and a second auxiliary exhaust valve 54 are respectively arranged on the other two side walls of the purification box 21, and the main exhaust valve 52, the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 are all hinged rotating doors; a control valve 11 is provided on the two outlet pipes 33.

[0026] The outside air enters the upper box body 1 from the air inlet 31 under the action of the air pump 32, and is treated under the action of the TiO2 photocatalytic device (the TiO2 photocatalytic device is a prior art and will not be described in detail here (i.e., the air is irradiated by the fluorescent lamp in the TiO2 photocatalytic device, so that the titanium dioxide layer in the TiO2 photocatalytic device is activated and generates free radicals with high catalytic activity, which can catalyze organic matter such as formaldehyde and some inorganic matter); the air treated by the TiO2 photocatalytic device is discharged from the air outlet of the air pump 32, and then enters the purification box 21 through the air outlet pipe 33; then it is filtered under the action of the intermediate filter plate assembly 4 and the regulating filter plate assembly 5; and finally it is discharged from the main exhaust valve 52, the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54.

[0027] According to the need for purification, the control valve 11 on one of the two air outlet pipes 33 can be closed, so that after the outside air enters the upper box body 1, it enters one of the purification boxes 21 through the other air outlet pipe 33 (the main exhaust valve 52, the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 on this purification box 21 are all closed), and then can be filtered through the intermediate filter plate assembly 4 and the adjusting filter plate assembly 5 before being discharged (at this time, the adjusting filter plate 51 and the intermediate filter plate assembly 4 are arranged in parallel and side by side, so that after the outside air enters the upper box body 1, it can be filtered through the intermediate filter plate assembly 4 and the adjusting filter plate assembly 5 in sequence under the action of the air pump 32; at the same time, the main exhaust valve 52, the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 on the other purification box 21 are opened).

[0028] When only the outside air needs to be processed through the TiO2 photocatalytic device, first open the control valves 11 on the two outlet pipes 33, so that the outside air enters the upper box body 1 from the air inlet 31 under the action of the vacuum pump 32. After being processed under the action of the TiO2 photocatalytic device, it enters the two purification boxes 21 respectively through the two outlet pipes 33, and is discharged from the main exhaust valve 52, the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 on the purification box 21.

[0029] Example 2 Based on the first embodiment, Figures 5 to 8 As shown, a guide plate 12 is provided on the bottom surface of the upper box body 1, and a waist-shaped chute 13 is provided on the guide plate 12. A guide rod 14 is provided on the top surface of the filter plate frame 511, and the guide rod 14 is movably arranged in the waist-shaped chute 13; the end of the guide rod 14 away from the top surface of the filter plate frame 511 is an external threaded rod structure, and the end of the guide rod 14 away from the top surface of the filter plate frame 511 is threadedly connected with a locking nut 15, and the locking nut 15 conflicts with the bottom surface of the upper box body 1; it is convenient to adjust the position of the filter plate frame 511 and the filter plate 51 according to different filtering needs. The guide rod 14 can slide in the waist-shaped slide groove 13 (that is, the adjustment filter plate 51 and the intermediate filter plate assembly 4 are arranged parallel to each other or vertically to each other), which is beneficial to maintaining the position of the adjustment filter plate frame 511 and the adjustment filter plate 51 stable, and is convenient for preventing the adjustment filter plate frame 511 from rotating during the air purification process after the adjustment position is adjusted; when the position of the adjustment filter plate frame 511 is adjusted, the locking nut 15 is tightened to prevent the adjustment filter plate frame 511 from rotating during the air purification process after the adjustment position is adjusted.

[0030] Example 3 Based on the first embodiment, Figures 2 to 7As shown, the adjustable filter plate frame 511 has arc-shaped elastic sealing plates 55 movably provided on both opposite side walls, and the side wall of the purification box 21 away from the intermediate filter plate assembly 4 is adapted to the shape of the arc-shaped elastic sealing plate 55; the intermediate filter plate assembly 4 includes an intermediate filter plate frame 41, and the shape and size of the intermediate filter plate frame 41 are the same as those of the adjustable filter plate frame 511. The intermediate filter plate frame 41 is arranged at the middle position in the lower box body 2, and the intermediate filter plate frame 41 divides the interior of the lower box body 2 into two parallel purification boxes 21; the intermediate filter plate 42 is arranged in the intermediate filter plate frame 41, and the shape and size of the intermediate filter plate 42 are the same as those of the adjustable filter plate 51.

[0031] Two tube hole groups 6 are provided on the bottom surface of the upper box body 1. The two tube hole groups 6 are connected to the two purification boxes 21 one by one. Each tube hole group 6 is composed of two tube holes 61 distributed at intervals, and the two tube holes 61 correspond to the positions of the first auxiliary exhaust valve 53 and the second auxiliary exhaust valve 54 respectively. The two exhaust pipes 33 are respectively movable through one of the tube holes 61 in the two tube hole groups 6, and a hole plug is movably provided in each tube hole 61.

[0032] When the adjusting filter plate 51 and the intermediate filter plate assembly 4 are arranged in parallel, the intermediate filter plate frame 41 fits in contact with the adjusting filter plate frame 511, and the intermediate filter plate 42 is parallel to the adjusting filter plate 51; the arc-shaped elastic sealing plates 55 on the opposite side walls of the adjusting filter plate frame 511 can respectively contact the two opposite inner walls of the lower box body 2, thereby improving the sealing performance, so that when the control valve 11 on one of the two outlet pipes 33 is closed, the outside air enters one of the purification boxes 21 through the other outlet pipe 33 (the main exhaust valve 52, the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 on this purification box 21 are all closed), and then passes through the intermediate filter plate assembly 4 and the adjusting filter plate assembly 5 in turn for filtration; and then is discharged through the main exhaust valve 52, the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 on the other purification box 21.

[0033] When it is necessary to improve the air purification efficiency, first make the adjustment filter plate 51 and the intermediate filter plate assembly 4 vertically arranged (the arc-shaped elastic sealing plate 55 on the adjustment filter plate frame 511 close to the intermediate filter plate assembly 4 can be removed first), and the side wall of the intermediate filter plate frame 41 is perpendicular to the adjustment filter plate frame 511 (at this time, the position between the two pipe holes 61 corresponds to the position of the intermediate filter plate frame 41 up and down, and the intermediate filter plate frame 41 divides the interior of the lower box 2 into two parallel purification boxes 21); open the control valves 11 on the two outlet pipes 33 at the same time, and the outside air passes through the two outlet pipes. The air pipe 33 enters the two purification boxes 21 respectively, and can be filtered by the adjustable filter plate 51 respectively, and then discharged through the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 (at this time, the main exhaust valve 52 is closed; at the same time, the first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 is opened. When the first auxiliary exhaust valve 53 is opened, a hole plug is installed in the pipe hole 61 near the first auxiliary exhaust valve 53, and the air outlet pipe 33 passes through the other pipe hole 61 and is discharged into the purification box 21; that is, the opened first auxiliary exhaust valve 53 or the second auxiliary exhaust valve 54 is staggered with the position of the used pipe hole 61).

[0034] A plurality of insertion holes 43 are provided on the circumferential direction of the intermediate filter plate frame 41, and a plurality of insertion rods 44 corresponding to the insertion holes 43 are provided on the adjusting filter plate frame 511. When the intermediate filter plate 42 and the adjusting filter plate 51 are arranged in parallel, the insertion rods 44 are respectively inserted into the insertion holes 43 at the corresponding positions, and the depth of the insertion holes 43 is greater than twice the length of the insertion rods 44; when the intermediate filter plate 42 and the adjusting filter plate 51 are arranged in parallel, the insertion rods 44 can be respectively inserted into the insertion holes 43 at the corresponding positions, so as to improve the tightness and stability of the fit between the intermediate filter plate 42 and the adjusting filter plate 51, which is beneficial to improving the filtering and purification effect of the air.
