Description

Technical Field

[0001] The present invention relates to the technical field of air purification, in particular to an air purification device with a self-cleaning function. Background Art

[0002] The working principle of an air purifier is mainly based on a series of physical and chemical means to intercept, adsorb, decompose or inactivate pollutants in the air, so as to achieve the purpose of purifying the air. Some air purifiers mainly include structures such as blowers and multi-stage filtration systems. The blower generates wind pressure to suck the air around the air purifier into the multi-stage filtration system for physical purification, so as to achieve the purpose of air purification. If the air purifier needs to be placed in a corner of the room according to the use requirements, the blower generates wind pressure, so that the air around the air purifier enters the air purifier under the same wind pressure, and the side of the air purifier away from the corner can only absorb the air around the purifier, and cannot absorb air farther away from the room.

[0003] When the air purifier is in use, the multi-stage filtration system contains a pre-filter cartridge, which is used to filter larger particles of dust and other impurities. However, after long-term use, thick dust will accumulate on the outer surface of the pre-filter cartridge. The self-cleaning structure of the existing purifiers directly uses negative pressure suction to absorb the dust on the surface of the pre-filter cartridge from top to bottom. Although it can remove dust on a part of the surface of the pre-filter cartridge, it is not effective to use a single direction brushing when facing relatively firm dust and other impurities, which makes it more difficult for air to enter the multi-stage filtration system and reduces the air purification efficiency. In view of this, we propose an air purification device with a self-cleaning function. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the air purification device with self-cleaning function, the cleaning mechanism is driven by the electric slide rail to reciprocate along the vertical direction, and the inner side of the cleaning mechanism moves along the outer surface of the steel wire drum. The cleaning mechanism generates a longitudinal cleaning force on the surface of the steel wire drum to scrape off the dust and other impurities on the surface of the steel wire drum, and cooperates with the operation and swing of the cleaning mechanism itself to generate a lateral force on the surface of the steel wire drum. The combination of the longitudinal and lateral forces can fully and thoroughly clean the stubborn dust and other impurities on the surface of the steel wire drum, prevent impurities from being deposited on the surface of the steel wire drum, and cause the surface of the steel wire drum to be blocked, so that it is more convenient for air to pass through the steel wire drum, which is beneficial to improving the air purification efficiency. The movement of the cleaning mechanism cooperates with the stabilizing mechanism, so that the cleaning mechanism has stronger structural stability when working and is not easy to shake, which is beneficial to further improve the cleaning efficiency of the steel wire drum surface and enhance the cleaning effect.

[0016] 2. In the air purification device with self-cleaning function, when the outside air is introduced into the fuselage through the pneumatic mechanism, the air flows through the pneumatic mechanism and the switching mechanism, and is ejected from the ventilation mechanism, so that the air to be purified is blown on the steel wire drum. On the one hand, when the purifier is placed in the corner of the room for use, the air at a farther position in the room can be introduced into the fuselage, thereby accelerating the air circulation speed. On the other hand, when the cleaning mechanism finishes cleaning the steel wire drum, when the pneumatic mechanism is used to spray air at a faster speed on the steel wire drum, the air will flush out the residual dust blocked in the holes on the surface of the steel wire drum, thereby preventing the steel wire drum from being blocked, thereby further improving the cleaning effect of the cleaning mechanism. Moreover, the switching mechanism is used to rotate with the pneumatic mechanism. When the cleaning mechanism cleans the surface of the steel wire drum, the pneumatic mechanism introduces the dust-containing air on the periphery of the steel wire drum into the ventilation mechanism. The dust-containing air flows through the switching mechanism into the pneumatic mechanism, and the dust is retained in the pneumatic mechanism. The clean air flows out of the pneumatic mechanism and the fuselage, thereby preventing the dust from flying around when cleaning the steel wire drum, thereby further improving the cleaning effect.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The self-cleaning structure of existing air purifiers directly uses negative pressure suction to absorb dust on the surface of the pre-filter cartridge. Although it can remove dust on a portion of the surface of the pre-filter cartridge, it cannot absorb relatively firm dust and other impurities attached to the surface of the pre-filter cartridge. Furthermore, if the air purifier needs to be placed in a corner of a room according to use requirements, the side of the air purifier away from the corner can only absorb air around the purifier, and cannot absorb air farther away from the room.

[0034] To this end, the present invention provides an air purification device with a self-cleaning function. Figure 1-Figure 13It includes a fuselage 1, an end cover 2 is installed on the top of the fuselage 1, a blower 3 is installed inside the end cover 2, an input end of the blower 3 is connected to the inside of the fuselage 1, a steel wire cylinder 4 is installed at the bottom center of the inner wall of the fuselage 1, and a high-efficiency air filter, a carbon filter and an ultraviolet lamp and other structures are also arranged on the inside of the steel wire cylinder 4. The high-efficiency air filter is made of fine fiber material and can filter impurities such as particles or smoke particles that the steel wire cylinder 4 cannot filter. The carbon filter is mainly made of activated carbon and can absorb odors or some bacteria that the steel wire cylinder 4 and the high-efficiency filter cannot filter and absorb. The ultraviolet lamp can generate ultraviolet rays to kill viruses or bacteria that may still be in the air. The blower 3 includes structures such as an impeller and a motor. The motor drives the impeller to rotate, thereby driving the air near the fuselage 1 and the end cover 2 into the fuselage. 1, and then sequentially passes through the steel wire drum 4, the high-efficiency air filter, the carbon filter and the ultraviolet lamp and other structures, so as to complete the air purification. An electric slide rail 10 is fixedly arranged on one side of the inner wall of the fuselage 1. The electric slide rail 10 includes structures such as a motor and a screw rod. The motor drives the screw rod to rotate to convert the rotary motion into a linear motion. A cleaning mechanism 6 for cleaning dust and other impurities on the surface of the steel wire drum 4 is arranged at the output end of the electric slide rail 10 to generate a longitudinal cleaning force, and the cleaning mechanism 6 itself operates and swings to generate a lateral cleaning force. The electric slide rail 10 drives the cleaning mechanism 6 to reciprocate in the vertical direction to clean the dust on the surface of the steel wire drum 4, and the steel wire drum 4 is arranged on the inner side of the cleaning mechanism 6. A stabilizing mechanism 7 for improving the structural stability of the cleaning mechanism 6 when it moves is arranged on one side of the cleaning mechanism 6;

[0035] A pneumatic mechanism 8 for generating wind pressure is provided at one end of the bottom of the inner wall of the fuselage 1, a switching mechanism 9 is provided on one side of the pneumatic mechanism 8, the switching mechanism 9 rotates to cooperate with the pneumatic mechanism 8 to change the air flow path, a ventilation mechanism 5 for circulating air is provided on one side of the switching mechanism 9, and the ventilation mechanism 5 cooperates with the cleaning mechanism 6 to absorb the swept dust, and the ventilation mechanism 5 is provided on the cleaning mechanism 6, wherein:

[0036] The present invention Figure 1-3 As shown, considering that the steel wire cylinder 4 is used to filter larger particles of dust and other impurities, after long-term use, thick dust will accumulate on the outer surface of the steel wire cylinder 4. The self-cleaning structure of the existing purifier is mostly directly sucked from the top to the bottom by negative pressure suction. Although the dust on a part of the surface of the steel wire cylinder 4 can be removed, the relatively firm dust and other impurities attached to the surface of the steel wire cylinder 4 cannot be sucked, and the cleaning effect is not good. The residual dust continues to block the steel wire cylinder 4, making it more difficult for air to pass through the steel wire cylinder 4, thereby reducing the air purification efficiency. Therefore, as shown in FIG. Figure 2 and Figure 4 As shown, the cleaning mechanism 6 is driven by the electric slide rail 10 to reciprocate along the vertical direction (as shown in FIG. Fig. 9As shown in the figure, the inner side of the cleaning mechanism 6 moves along the outer surface of the steel wire drum 4, and the cleaning mechanism 6 generates a longitudinal cleaning force on the surface of the steel wire drum 4 to scrape off the dust and other impurities on the surface of the steel wire drum 4, and cooperates with the operation and swing of the cleaning mechanism 6 itself to generate a lateral force on the surface of the steel wire drum 4. The longitudinal and lateral forces are combined to fully and thoroughly clean the dust and other impurities stubbornly attached to the surface of the steel wire drum 4, prevent the impurities from being deposited on the surface of the steel wire drum 4, and cause the surface of the steel wire drum 4 to be blocked, so that the air passes through the steel wire drum 4 more conveniently, which is conducive to improving the air purification efficiency, and the movement of the cleaning mechanism 6 cooperates with the stabilizing mechanism 7, so that the cleaning mechanism 6 has a stronger structural stability when working, and is not easy to shake, which is conducive to further improving the cleaning efficiency of the surface of the steel wire drum 4 and enhancing the cleaning effect;

[0037] Furthermore, if the body 1 is placed in a corner of a room according to the use requirements, the blower 3 generates wind pressure, so that the air around the body 1 enters the body 1 under the same wind pressure, and the side of the body 1 away from the corner can only absorb the air around the purifier, and cannot absorb the air farther away from the room, resulting in poor air circulation. Therefore, if Figure 3 and Figure 4 As shown, when the outside air is introduced into the fuselage 1 through the pneumatic mechanism 8, the air flows through the pneumatic mechanism 8 and the switching mechanism 9, and is ejected from the ventilation mechanism 5, so that the air to be purified is blown on the steel wire cylinder 4. On the one hand, when the purifier is placed in a corner of a room for use, the air at a farther position in the room can be introduced into the fuselage 1, thereby accelerating the air circulation speed. On the other hand, when the cleaning mechanism 6 finishes cleaning the steel wire cylinder 4, the pneumatic mechanism 8 is used to spray the air on the steel wire cylinder 4 at a faster speed, and the air will break through the holes blocked on the surface of the steel wire cylinder 4. The residual dust in the wire drum 4 is prevented from being blocked, and the cleaning effect of the cleaning mechanism 6 is further improved. The switching mechanism 9 is used to rotate with the pneumatic mechanism 8. When the cleaning mechanism 6 cleans the surface of the wire drum 4, the pneumatic mechanism 8 introduces the dust-containing air on the side of the wire drum 4 into the ventilation mechanism 5. The dust-containing air flows through the switching mechanism 9 and enters the pneumatic mechanism 8. The dust is retained in the pneumatic mechanism 8, and the clean air flows out of the pneumatic mechanism 8 and the fuselage 1, preventing the dust from flying around when cleaning the wire drum 4, which is conducive to further improving the cleaning effect.

[0038] On the basis of the above, the specific structure is disclosed in detail:

[0039] To realize the self-movement of the cleaning mechanism 6 to clean the surface of the wire drum 4 and prevent the wire drum 4 from being blocked, the specific structure of the cleaning mechanism 6 is disclosed. Figure 4 and Figure 7As shown, the cleaning mechanism 6 includes a cylinder 61, the tail end of the cylinder 61 is hingedly arranged on the output end of the electric slide rail 10, and the output end of the cylinder 61 is hingedly provided with an annular brush 62 for cleaning the surface of the wire drum 4. The inner wall of the annular brush 62 contacts the outer wall of the wire drum 4. The cylinder 61 is periodically and repeatedly extended and shortened to drive the annular brush 62 to reciprocate in the horizontal direction (such as Figure 8 and Fig.13 As shown in the figure, the bristles on the annular brush 62 are in contact with the outer surface of the wire drum 4, so that the bristles of the annular brush 62 clean the dust on the surface of the wire drum 4 in the horizontal direction (lateral force), and cooperate with the electric slide rail 10 to drive the cylinder 61 and the annular brush 62 to move up and down in the vertical direction (longitudinal force), driving the bristles of the annular brush 62 to clean the dust on the surface of the wire drum 4 in the vertical direction. The lateral and longitudinal forces cooperate with each other to clean the outer surface of the wire drum 4, preventing a large amount of dust from being deposited on the surface of the wire drum 4, causing the surface of the wire drum 4 to be blocked, so that the air passes through the wire drum 4 faster, which is beneficial to improving the air purification efficiency and reducing the workload.

[0040] Among them, in order to make the annular brush 62 and the cylinder 61 move in the vertical direction under the drive of the electric slide rail 10, the structural stability is better and the cleaning effect is improved, it is necessary to disclose the specific structure of the stabilizing mechanism 7. Figure 4-5 As shown, the stabilizing mechanism 7 includes a guide rail 71, and the side of the guide rail 71 away from the annular brush 62 is fixedly arranged on the fuselage 1, and a moving block 72 is slidably arranged on the surface of the guide rail 71. The end of the moving block 72 close to the annular brush 62 is provided with a slot, and a limit block 73 is slidably arranged in the slot. The end of the limit block 73 away from the moving block 72 is arranged on the ventilation mechanism 5, and the annular brush 62, the cylinder 61 and the ventilation mechanism 5 are driven to move in the vertical direction by the electric slide rail 10, and the moving block 72 is driven to move along the guide rail 71, so that the annular brush When 62 and the cylinder 61 move along the vertical direction to clean the surface of the wire drum 4, the annular brush 62 will not shake at will, so that the annular brush 62 can better clean the dust on the surface of the wire drum 4, and when the cylinder 61 drives the annular brush 62 to rotate back and forth, it drives the limit block 73 to slide in the groove, and the limit block 73 will not fall out of the groove. The groove limits the movement of the limit block 73, so that the limit block 73 moves in the horizontal direction, so that the annular brush 62 has stronger structural stability when it rotates back and forth horizontally, further improving the cleaning effect of the annular brush 62.

[0041] Considering that the annular brush 62 reciprocates and cleans the dust on the surface of the wire drum 4 as the electric slide rail 10 reciprocates in the vertical direction, the dust leaves the surface of the wire drum 4 and needs to be collected by the ventilation mechanism 5 to prevent the dust from floating around, and the ventilation mechanism 5 cannot hinder the annular brush 62 from moving up and down, it is necessary to disclose the specific structure of the ventilation mechanism 5. Therefore, as Figure 3-4As shown, the ventilation mechanism 5 includes an annular air duct 51, which is fixedly arranged on the outer wall of the annular brush 62, and the end of the limit block 73 away from the moving block 72 is fixedly arranged on the annular air duct 51, and the outer wall of the annular air duct 51 close to the end cover 2 is fixedly connected with a plurality of L-shaped air ducts 52, and the end face of the L-shaped air duct 52 faces the steel wire drum 4, and the plurality of L-shaped air ducts 52 are distributed in an annular shape around the steel wire drum 4, and the outer wall of the annular air duct 51 away from the steel wire drum 4 is fixedly connected with a hose 53, and the end of the hose 53 away from the annular air duct 51 is fixedly connected with a first ventilation pipe 54, and wind pressure is generated by the pneumatic mechanism 8, so that the end face of the L-shaped air duct 52 generates suction. The dust generated by the annular brush 62 cleaning the surface of the wire drum 4 floats on the side of the wire drum 4 and is mixed in the air. The suction force draws the dust-containing air into the annular air duct 51 through the L-shaped air duct 52. The air containing dust and other impurities continues to enter the hose 53 and the first ventilation pipe 54 through the annular air duct 51. The hose 53 has a certain flexibility and will not hinder the annular brush 62 from moving in the vertical direction to clean the surface of the wire drum 4. The dust-containing air enters the switching mechanism 9 through the first ventilation pipe 54, and then enters the pneumatic mechanism 8. The pneumatic mechanism 8 filters the dust in the air, thereby preventing the cleaned dust from flying around, further improving the cleaning effect.

[0042] Considering the use requirements of the pneumatic mechanism 8 in different occasions, when the pneumatic mechanism 8 needs to filter dust in the air containing dust, it needs to be matched by the rotation of the switching mechanism 9, so it is necessary to disclose the specific structure of the switching mechanism 9. Figure 4 and Figure 6 As shown, the switching mechanism 9 includes a second ventilation pipe 91, one end of the second ventilation pipe 91 close to the wire drum 4 is fixedly connected to the first ventilation pipe 54, and the end of the second ventilation pipe 91 away from the wire drum 4 is fixedly connected to a switching box 92, and a motor is fixedly installed on the side of the switching box 92 close to the wire drum 4. A switching block 93 is fixedly provided on the output end of the motor through the switching box 92, and an opening is provided on one side of the switching block 93. A third ventilation pipe 94 is provided on the bottom end of the side of the switching box 92 away from the wire drum 4, and the opening is connected to the third ventilation pipe 94. The third ventilation pipe 94 is connected and arranged on the pneumatic mechanism 8. Through the switching box 92 and the cutting slider, air containing impurities such as dust enters the switching box 92 through the hose 53, the first ventilation pipe 54 and the second ventilation pipe 91, and then flows through the opening and the third ventilation pipe 94 into the pneumatic mechanism 8 (as shown in FIG. Fig.11 As shown), dust and other impurities in the air are filtered out by the pneumatic mechanism 8, which prevents the cleaned dust from flying around and improves the cleaning effect.

[0043] Considering that the pneumatic mechanism 8 needs to filter the dust mixed in the air, it is necessary to disclose the specific structure of the pneumatic mechanism 8. Figure 4 and Figure 6As shown, the pneumatic mechanism 8 includes an equipment box 81, which is fixedly arranged at one end of the bottom of the inner wall of the fuselage 1. The interior of the equipment box 81 is divided into a first chamber and a second chamber by a filter screen 82. The end of the third ventilation pipe 94 away from the switching box 92 is fixedly connected to the second chamber. The air containing impurities such as dust flowing through the third ventilation pipe 94 passes through the filter screen 82 and enters the second chamber. The air continues to flow from the second chamber to the first chamber. The dust and other impurities in the air are retained under the filter screen 82 to prevent the dust and other impurities in the air from flying around, thereby improving the cleaning effect.

[0044] Among them, since the pneumatic mechanism 8 is required to generate power to collect dust and other impurities cleaned off the surface of the wire drum 4, it is necessary to continue to disclose the specific structure of the pneumatic mechanism 8, such as Figure 4 and Figure 6 As shown, the side of the device box 81 away from the switch box 92 is fixedly connected with a channel 83, the end of the channel 83 close to the switch box 92 is fixedly connected to the first chamber, and the end of the channel 83 away from the switch box 92 passes through the fuselage 1 and communicates with the outside world. A through hole is opened below the connection between the fuselage 1 and the channel 83, and is covered by a cover plate (such as Figure 6 As shown), the device box 81 is provided with a closed door (as shown Figure 4 As shown in the figure, the closed door is connected to the second chamber. The user needs to regularly remove the cover plate, open the closed door, and clean the dust and other impurities accumulated in the second chamber. A fan 84 is fixedly arranged on the inner wall of the channel 83. Through the fan 84 and the channel 83, the fan 84 is used to generate suction at the end face of the L-shaped air duct 52 by forward or reverse rotation, and the dust swept by the annular brush 62 is mixed with air and sucked into the annular air duct 51, and enters the second chamber through the hose 53, the first ventilation pipe 54 and the third ventilation pipe 94. The dust and other impurities are filtered out by the filter net 82, and the air without dust and other impurities flows through the first chamber and the channel 83, and is discharged to the outside of the fuselage 1, thereby completing the collection of the dust cleaned from the wire drum 4, preventing the dust from flying around, and further improving the cleaning effect.

[0045] Among them, when the purifier is placed in a corner of the room for use (such as Fig.10 As shown), the fan 84 needs to be reversed or forwarded to generate power to send the air waiting to be purified into the interior of the fuselage 1, and be purified by the steel wire tube 4 and other structures to expand the air purification range of the purifier and speed up the indoor air circulation. It is necessary to continue to disclose the specific structure of the switching mechanism 9. Therefore, as Figure 4 , Figure 6 and Fig.12As shown, the top of the side of the switching box 92 away from the wire drum 4 is fixedly connected with a fourth ventilation pipe 95, and the end of the fourth ventilation pipe 95 away from the switching box 92 is connected to the first chamber. The side of the switching box 92 close to the wire drum 4 is fixedly connected with a fifth ventilation pipe, and the end of the fifth ventilation pipe away from the switching box 92 is also fixedly connected to the first ventilation pipe 54. Through the fourth ventilation pipe 95 and the fifth ventilation pipe, the motor is started to rotate, driving the switching block 93 to rotate 180 degrees, so that the two ends of the opening are connected to the fourth ventilation pipe 95 and the fifth ventilation pipe respectively (as shown in FIG. Fig.12 As shown), at this time, the fan 84 is used to generate power by reverse or forward rotation to accelerate the indoor air flow, and the air in the indoor space away from the purifier is sucked into the channel 83, and the air waiting to be purified continues to flow into the first chamber. On the one hand, the air waiting to be purified passes through the filter 82, and the dust attached to the filter 82 is blown off to the bottom of the second chamber to prevent the dust from adhering to the filter 82 and affecting the filtering effect of the filter 82. On the other hand, since the third ventilation pipe 94 is blocked by the switching block 93 (as shown in FIG. Fig.12 As shown), the air to be purified flows through the fourth ventilation duct 95, the opening and the fifth ventilation duct into the first ventilation duct 54, and the air continues to flow, flows through the annular air duct 51 and the L-shaped air duct 52, and flows out from multiple L-shaped air ducts 52, and blows to the surface of the steel wire drum 4. The air is purified by the steel wire drum 4 and other structures, thereby achieving the purpose of expanding the air purification range of the purifier and accelerating the indoor air circulation. In the process of the annular brush 62 cleaning the steel wire drum 4, the above-mentioned process of rotating the fan 84 to introduce the air to be purified and blowing it onto the steel wire drum 4 is appropriately repeated several times, which can also dredge the surface of the steel wire drum 4 that may not be cleaned by the annular brush 62, thereby further improving the cleaning effect.

[0046] Working principle: When the purifier is needed, start the blower 3 to rotate, driving the air around the body 1 and the end cover 2 into the body 1, and then the air passes through the steel wire drum 4, the high-efficiency air filter, the carbon filter and the ultraviolet lamp in sequence, and is discharged from the exhaust port of the blower 3, enters the end cover 2, and is then discharged from the ventilation part of the end cover 2, thereby completing the air purification operation;

[0047] When it is necessary to clean the surface of the steel wire drum 4 regularly, the blower 3 is turned off to temporarily stop the air purification operation of the device, and the electric slide rail 10 is started to work, driving the cylinder 61 and the annular brush 62 to move up and down in the vertical direction, driving the bristles of the annular brush 62 to clean the dust on the surface of the steel wire drum 4 in the vertical direction. At the same time, the cylinder 61 is started to repeatedly extend and shorten, driving the annular brush 62 to reciprocate in the horizontal direction, and the bristles on the annular brush 62 are in contact with the outer surface of the steel wire drum 4, so that the bristles of the annular brush 62 clean the dust on the surface of the steel wire drum 4 in the horizontal direction, thereby achieving the purpose of cleaning the dust on the steel wire drum 4;

[0048] When the dust cleaned by the annular brush 62 is collected, at this time, the opening on the switching block 93 is connected to the third ventilation pipe 94, and the fan 84 is started to rotate forward (or reverse), thereby generating suction at the end surface of the L-shaped air duct 52, and the dust and air swept by the annular brush 62 are sucked into the annular air duct 51 together with the annular air duct 51 (the annular air duct 51 reciprocates along the vertical direction with the annular brush 62), and enter the second chamber through the hose 53, the first ventilation pipe 54 and the third ventilation pipe 94, and the dust and other impurities are filtered out by the filter 82, and the air without dust and other impurities flows through the first chamber and the channel 83, and is discharged to the outside of the fuselage 1, completing the collection of the dust cleaned on the wire drum 4;

[0049] When the purifier is placed in a corner of a room for use, the motor is started to drive the switching block 93 to rotate 180 degrees, so that the two ends of the opening are connected to the fourth ventilation pipe 95 and the fifth ventilation pipe respectively, and the fan 84 is started to reverse (or forward) to accelerate the indoor air flow, and the air in the indoor space away from the purifier is sucked into the channel 83, and the air waiting to be purified continues to flow into the first chamber. On the one hand, the air waiting to be purified passes through the filter 82, and the dust attached to the filter 82 is blown off to the bottom of the second chamber to prevent the dust from adhering to the filter 82. On the other hand, since the third ventilation pipe 94 is switched Block 93 is blocked, and the air waiting to be purified flows through the fourth ventilation duct 95, the opening and the fifth ventilation duct into the first ventilation duct 54. The air continues to flow, flows through the annular air duct 51 and the L-shaped air duct 52, and flows out from multiple L-shaped air ducts 52 and blows to the surface of the wire drum 4. The air is purified by the steel wire drum 4 and other structures, so as to expand the air purification range of the purifier. In addition, in the process of the annular brush 62 cleaning the steel wire drum 4, the process of the fan 84 rotating to introduce the air to be purified and blowing it onto the steel wire drum 4 is appropriately repeated several times, which can also dredge the surface of the steel wire drum 4 that may not be cleaned by the annular brush 62 to improve the cleaning effect.
