Description

Technical Field

[0001] The invention relates to a fresh air purification device. Background Art

[0002] As society becomes more and more modernized, people's production and lifestyles have also changed greatly. People spend more and more time working, living and doing activities indoors. Work, entertainment, sports and other activities can all be done indoors. According to statistics, people spend an average of more than 80% of their time indoors every day. Therefore, indoor air quality has a vital impact on human health.

[0003] At present, there are fresh air ventilators on the market for replacing fresh air. When the fresh air ventilator is working, outdoor air enters the ventilator from the outdoor air inlet, and then passes through the primary filter, medium filter, and electrostatic dust removal box in turn to remove impurities in the outside air. At the same time, indoor air enters the ventilator from the indoor air inlet, and the heat of the indoor air is exchanged to the new air coming in from the outside through the heat exchanger. After that, the new air enters the room after further processing, and the old indoor air is discharged to the outside. Although the above-mentioned fresh air ventilator can effectively purify indoor air, after the ventilator is used for a long time, the filtered dust particles are easy to adhere to the primary filter, medium filter and electrostatic dust removal box, causing them to be blocked, which leads to poor air filtration effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a fresh air purification device with a simple structure and a replaceable adhesive wheel of the adhesive wheel mechanism in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the fresh air purification device comprises a casing, the casing having a fresh air inlet and a fresh air outlet, and is characterized in that a filter cartridge, a viscose wheel mechanism and a fan are installed inside the casing, the outer peripheral surface of the filter cartridge is the air inlet surface, one end of the filter cartridge is a closed end, and the other end of the filter cartridge is an air outlet end connected to the air inlet of the fan, the air outlet of the fan is connected to the fresh air outlet, the viscose wheel mechanism has at least two viscose wheel groups and one of the viscose wheel groups can be selected to cooperate with the filter cartridge, and the dust attached to the air inlet surface of the filter cartridge after filtration is adhered to the viscose structure of the matching viscose wheel group.

[0006] Preferably, each of the viscose wheel groups includes a first roller, a second roller and a first motor for driving the first roller and the second roller to rotate. The viscose tape is wound around the first roller and gradually wound around the second roller under the drive of the above-mentioned first motor to form the viscose structure. The viscose structure cooperates with the air inlet surface of the filter cartridge to drive the filter cartridge to rotate, and then the dust on the air inlet surface of the filter cartridge is adhered to the viscose structure.

[0007] There may be multiple viscose wheel groups. Preferably, the viscose wheel mechanism includes two viscose wheel groups and a second motor driving the two viscose wheel groups to rotate as a whole, and one of the viscose wheel groups is matched with the filter cartridge by the drive of the second motor.

[0008] Further preferably, the adhesive wheel mechanism further includes a cross bracket, the two first rollers and the two second rollers of the adhesive wheel mechanism are respectively mounted on the four ends of the cross bracket, and the center of the cross bracket is mounted on the output shaft of the second motor. In this way, under the drive of the second motor, the two adhesive wheel groups can be driven to rotate as a whole.

[0009] Preferably, the first drum is mounted on the output shaft of the second motor, so that the first motor directly drives the second drum to rotate, and then drives the filter drum to rotate synchronously.

[0010] In order to make the fresh air flow into the casing more smoothly, the air outlet of the filter cartridge faces the air inlet of the fan, and the air outlet of the fan faces the fresh air outlet.

[0011] Further preferably, the fan is a centrifugal fan.

[0012] Compared with the prior art, the advantages of the present invention are that the glue wheel mechanism of the fresh air purification device has at least two glue wheel groups. After filtering, the dust attached to the air inlet surface of the filter cartridge is adhered to the glue structure of the matching glue wheel group. After the glue of one glue wheel group is used up, the driving mechanism can be used to rotate the other glue wheel group to a position matching the filter cartridge. It is more flexible to use and extends the service life of the glue wheel mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in detail below with reference to the accompanying drawings.

[0018] like Figures 1 to 3 As shown, the fresh air purification device in this embodiment includes a housing 1, and the housing 1 has a fresh air inlet 11 and a fresh air outlet 12. A filter cartridge 2, a viscose wheel mechanism 3 and a fan 4 are installed inside the housing 1. The filter cartridge 2 adopts a metal filter structure, the outer peripheral surface of the filter cartridge 2 is the air inlet surface, one end of the filter cartridge 2 is a closed end, and the other end of the filter cartridge 2 is an air outlet end connected to the air inlet of the fan 4. The air outlet of the filter cartridge 2 faces the air inlet of the fan 4, and the air outlet of the fan 4 faces the fresh air outlet 12 and is connected to the fresh air outlet 12. Among them, the fan 4 adopts a centrifugal fan.

[0019] In this embodiment, the adhesive wheel mechanism 3 has two adhesive wheel groups 31, each adhesive wheel group 31 includes a first roller 311, a second roller 312 and a first motor 313, the second roller 312 is installed on the output shaft of the first motor 313, and the adhesive tape 314 is pre-wound on the first roller 311. When the first motor 313 is working, the adhesive tape 314 on the first roller 311 is gradually wound around the second roller 312 to form an adhesive structure, and the adhesive structure cooperates with the air inlet surface of the filter cartridge 2 to drive the filter cartridge 2 to rotate, and then the dust on the air inlet surface of the filter cartridge 2 is adhered to the adhesive structure.

[0020] The adhesive wheel mechanism 3 also includes a cross bracket 33 and a second motor 32. The two first rollers 311 and the two second rollers 312 of the adhesive wheel mechanism 3 are respectively mounted on the four ends of the cross bracket 33, and the center of the cross bracket 33 is mounted on the output shaft of the second motor 32. The second motor 32 can drive the cross bracket 33 to rotate, thereby driving the two adhesive wheel groups 31 to rotate as a whole, so that one of the adhesive wheel groups 31 is matched with the filter cartridge 2, that is, the dust attached to the air inlet surface of the filter cartridge 2 after filtering is adhered to the adhesive structure of the matched adhesive wheel group 31.

[0021] like Figure 4 As shown, the fresh air purification device is wall-mounted, and a fresh air passage 51 connecting the fresh air inlet 11 and the outside is opened on the wall 5. A solar rain cover 6 is installed at the air inlet of the fresh air passage 51, and the solar rain cover 6 can be opened or closed as needed. When the purification device is not in use, the solar rain cover 6 closes the fresh air passage 51. When the purification device is enabled, the solar rain cover 6 is opened to prevent rainwater from entering the fresh air purification device through the fresh air passage 51.

[0022] When the fresh air purification device is working, outdoor air enters the housing 1 through the fresh air channel 51 and the fresh air inlet 11 in sequence, and enters the fan 4 after passing through the filter cartridge 2. At the same time, driven by the second roller 312 of one of the adhesive wheel groups 31, the filter cartridge 2 rotates, and the dust particles on the outer peripheral surface of the filter cartridge 2 are adhered to the adhesive structure of the second roller 312. When the adhesive tape on the first roller 311 of the adhesive wheel group 31 is completely used up, the second motor 32 starts to rotate and the other adhesive wheel group 31 is used up. After the adhesive tapes 314 of the two adhesive wheel groups 31 are completely used up, new adhesive tapes 314 can be reinstalled, which is very convenient to use.
