[0019] The present invention has the following beneficial effects:
[0020] 1. The air purifier filter element, which is easy to disassemble and assemble, forms a tortuous multi-faceted structure by cooperating with the filter cloth and several rotating shafts. By winding the filter cloth around multiple rotating shafts, it not only significantly increases the effective surface area of the filter cloth, but also increases the contact time and efficiency of the air and filter material through the multi-faceted tortuous path, further improving the air purification effect.
[0021] Not only that, through the cooperation of the placement seat and the pushing spring, when replacing the filter element body, one end of the placement seat is pulled to make the top of the placement seat move away from the purifier body. In this process, the originally compressed pushing spring releases the elastic force. Under the elastic force of the pushing spring, the placement plate moves upward and at the same time lifts up the filter element body placed on its upper side. Therefore, the upper end of the filter element body is higher than the height of the placement seat, making the filter element easier for the operator to take out and replace; at the same time, through the cooperation of the torsion spring and the connecting rod, after the filter element body is replaced, the placement seat is released. Through the torsion of the torsion spring, the placement seat can automatically return to its position, without the need for manual adjustment by the user, saving time.
[0022] 2. The air purifier filter element that is easy to disassemble and assemble can clean the contaminated surface while replacing the filter surface through the cooperation of the connecting shaft, the rotating shaft, the connecting sleeve, the air storage bag and the guide plate. During the rotation of the rotating shaft, the connecting shaft is rotated by the cooperation of the pulley set. During the rotation of the connecting shaft, the guide plate is driven to rotate by the cooperation of the elastic block and the resistance block. The ends of the two guide plates are close to each other, so that the air inlet is restricted, avoiding large-scale blowing as much as possible, and the wind is blown to the clean filter cloth.
[0023] Moreover, through the cooperation of the elastic block, the resistance block, the connecting block and the reset groove, as the rotating shaft drives the connecting shaft to rotate continuously, the end of the connecting block reaches the inside of the reset groove, and the pulling spring drives the resistance block to descend into the air storage tank, thereby achieving the purpose of disengaging the connecting sleeve from the connecting shaft, and the reset of the guide plate is achieved through the cooperation of the volute spring. At the same time, as the rotating shaft is continuously rotated, the reciprocating rotation effect of the guide plate is achieved. During the reciprocating rotation of the guide plate, the guide plate continuously presses the air storage bag, so that the gas inside the air storage bag reaches the inside of the cleaning rod through the connecting pipe, and at the same time, the gas is blown from the inside of the cleaning rod to the surface of the filter cloth, so that the dust on the surface of the filter cloth falls into the placement frame. Therefore, in the process of rotating the filter cloth, the contaminated surface is cleaned, so that the filter cloth is always in a high-efficiency filtration state, continuously providing clean air, and significantly improving the filtration efficiency.
[0024] 3. The air purifier filter element that is convenient for disassembly and assembly, through the cooperation of the rotating disc, connecting shaft, push rod, air storage cylinder and piston block, during the rotation of the rotating shaft, drives the push rod to expand and contract by means of the connecting shaft, and drives the piston block to slide inside the air storage cylinder during the expansion and contraction process. During the sliding process of the piston block, the effect of delivering air to the cleaning pipe is achieved. Therefore, the air pressure inside the cleaning pipe is further enhanced. Thus, the strengthened air flow can prevent the filter cloth from being blocked as much as possible, ensuring smooth air circulation. It can not only maintain the high-efficiency filtering state of the filter cloth but also extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode
[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0037] Embodiment 1. The purpose of this embodiment is to promote the solution of the common folded design in the filter element of the air purifier. Although it seems that the filter paper is folded into a multi-layer structure, in fact, the filter paper itself is still a single-layer material. However, the physical structure of the single-layer filter paper determines its limited ability to capture large-area pollutants. For those air purifiers that must rely on physical filtration methods, when the particulate matter captured on the filter paper accumulates to a certain extent, the filtration efficiency will decrease significantly, which may lead to the problem of poor indoor air quality. Please refer to Figure 1 - Figure 10, An air purifier filter element that is convenient for disassembly and assembly, including a purifier body 110 and a filter element body 120 movably installed on the purifier body 110. A placement seat 111 is movably installed on the purifier body 110, and the filter element body 120 is installed inside the placement seat 111. The filter element body 120 includes a placement frame 121 and a filter cloth 122. A number of rotating shafts 130 are installed inside the placement frame 121, and the filter cloth 122 is arranged on the number of rotating shafts 130. A rotating rod 131 is arranged inside the rotating shaft 130. A cleaning rod 132 for cleaning the filter cloth 122 is installed inside the placement frame 121. An air storage cylinder 133 and an air storage airbag 134 for supplying air to the cleaning rod 132 are installed inside the placement frame 121. A guiding plate 135 for pressing the air storage airbag 134 is installed inside the placement frame 121
[0038] The rotating rod 131 is movably inserted into the rotating shaft 130. A return spring 140 is installed between the rotating shaft 130 and the rotating rod 131. A convex rib 141 is installed inside the rotating shaft 130. One end of the rotating rod 131 movably penetrates the placement frame 121, the placement seat 111 and the purifier body 110
[0039] See Figure 1 、 Figure 2 And Figure 3 When specifically implemented, by winding the filter cloth 122 around a number of rotating shafts 130, the filter cloth 122 can be folded into multiple surfaces, and the folding surfaces are arranged in parallel. When air passes through this complex filter cloth 122 structure, it needs to pass through multiple folded surfaces, thereby increasing the path length of contact with the filter cloth 122. Since the air must pass through the filter cloth 122 of multiple surfaces, the contact time and contact area are increased, significantly improving the filtration efficiency and being able to capture fine particles and pollutants more effectively
[0040] A placement groove 112 for placing the filter element body 120 is opened inside the placement seat 111. A placement plate 113 is installed inside the placement groove 112. A pushing spring 114 is installed between the placement plate 113 and the placement groove 112. A connecting rod 115 is installed inside the placement seat 111. The connecting rod 115 is rotationally matched with the housing of the purifier body 110. A torsion spring 116 is installed between the connecting rod 115 and the housing of the purifier body 110. Through the setting of the torsion spring 116, when the operator pulls the placement seat 111, the torsion spring 116 is stressed and unfolds; when the placement seat 111 is no longer controlled, the torsion spring 116 resets and drives the placement seat 111 back into the purifier body 110
[0041] See Figure 1 、 Figure 2 And Figure 3, During specific implementation, when replacing the filter element body 120, manually press the rotating rod 131 to make the rotating rod 131 retract into the rotating shaft 130. At this time, pull the placement seat 111 to make one end of the placement seat 111 move away from the purifier body 110. During this process, the originally compressed pushing spring 114 releases its elastic force. Under the elastic force of the pushing spring 114, the placement plate 113 moves upward, and at the same time, the filter element body 120 placed on its upper side is lifted, so that the upper end of the filter element body 120 is higher than the height of the placement seat 111. By lifting the filter element body 120, the operator can easily take it out for replacement;
[0042] Moreover, after replacing the filter element body 120, release the placement seat 111. During this process, the placement seat 111 drives the placement seat 111 to reset through the torsion force of the torsion spring 116. At the same time, the end parts of the filter element body 120 and the rotating rod 131 are set to be arc-shaped. Therefore, the side wall of the purifier body 110 squeezes the filter element body 120 and the rotating rod 131, so that the filter element body 120 returns to the inside of the placement seat 111, and at the same time, the rotating rod 131 returns to the inside of the rotating shaft 130. Therefore, the placement seat 111 resets smoothly.
[0043] In this embodiment: Through the cooperation of the filter cloth 122 and several rotating shafts 130, by winding the filter cloth 122 around multiple rotating shafts 130 to form a tortuous multi-faceted structure, not only the effective surface area of the filter cloth 122 is significantly increased, but also the contact time and efficiency of air with the filter material are improved through the tortuous paths of multiple facets, further improving the air purification effect.
[0044] Moreover, through the cooperation of the placement seat 111 and the pushing spring 114, when replacing the filter element body 120, pull one end of the placement seat 111 to make the top of the placement seat 111 move away from the purifier body 110. During this process, the originally compressed pushing spring 114 releases its elastic force. Under the elastic force of the pushing spring 114, the placement plate 113 moves upward, and at the same time, the filter element body 120 placed on its upper side is lifted. Therefore, the upper end of the filter element body 120 is higher than the height of the placement seat 111, making it easier for the filter element to be taken out and replaced by the operator; at the same time, through the cooperation of the torsion spring 116 and the connecting rod 115, after replacing the filter element body 120, release the placement seat 111. Through the torsion force of the torsion spring 116, the placement seat 111 can automatically return to its original position without manual adjustment by the user, saving time.
[0045] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that since the filter cloth 122 has multiple surfaces, the surfaces on the back side of the filter cloth 122 are relatively clean and can be reused. However, when replacing the filter surface, the contaminated surface will return to the back side of the clean surface, and the dust on the contaminated surface will affect the air exchange during the air intake process. This embodiment is an improvement based on Embodiment 1. Specifically, please refer toFigures 1 - 9 A groove 142 is formed on the rotating rod 131, and the convex rib 141 is slidably engaged inside the groove 142. Through the cooperation of the convex rib 141 and the groove 142, when the rotating rod 131 is rotated, one of the rotating shafts 130 can be driven to rotate by the restriction of the convex rib 141.
[0046] See Figure 4 During specific implementation, when there is a lot of dust on the outer side of the filter cloth 122, the operator rotates the rotating rod 131. The rotating rod 131 drives one of the rotating shafts 130 to rotate by the cooperation of the convex rib 141 and the groove 142. At the same time, the filter cloth 122 is evenly wound around multiple rotating shafts 130 to form a continuous annular structure. When one of the rotating shafts 130 rotates, it can drive the entire filter cloth 122 to move. Therefore, the surface change of the filter cloth 122 is realized. The surface change function of the filter cloth 122 ensures that a clean surface of the filter cloth 122 is always exposed to the air during the air purification process, avoiding the reduction of the filtration efficiency due to the blockage of a single surface.
[0047] A vertical rod 220 is rotatably installed inside the placement frame 121. First bevel gears 221 are installed at both ends of the vertical rod 220, and second bevel gears 222 are installed on two connecting shafts 150. The first bevel gears 221 are meshed with the second bevel gears 222.
[0048] Connecting shafts 150 are symmetrically installed on the placement frame 121. Connecting sleeves 151 are sleeved on the surfaces of the two connecting shafts 150 with a gap. A guiding plate 135 is installed on the connecting sleeve 151. A pulley group 152 is installed between the rotating shaft 130 and the connecting shaft 150. A connecting ring 153 is installed on the inner wall of the placement frame 121. An air storage groove 154 is formed inside the connecting shaft 150. A resisting block 155 is movably inserted at one end of the air storage groove 154, and a connecting block 160 is movably installed at the other end of the air storage groove 154. A pulling spring 161 is installed between the resisting block 155 and the air storage groove 154.
[0049] A number of elastic blocks 162 are installed inside the connecting sleeve 151. The elastic blocks 162 are made of rubber or silica gel. The elastic blocks 162 are used to restrict the resisting block 155. When the resisting block 155 is clamped between every two elastic blocks 162, the connecting sleeve 151 will be driven to rotate during the rotation of the connecting shaft 150. The number of elastic blocks 162 is installed in an annular array inside the connecting sleeve 151. A reset groove 163 is formed inside the connecting ring 153. The reset groove 163 is an arc-shaped groove. A volute spring 170 is installed between one end of the connecting sleeve 151 and the placement frame 121. The volute spring 170 is used to reset the guiding plate 135.
[0050] See Figure 4 、 Figure 5 、 Figure 6 and Figure 7, during specific implementation, during the rotation of the rotating shaft 130, through the cooperation of the pulley group 152, one of the connecting shafts 150 rotates. During the rotation of one connecting shaft 150, the second bevel gear 222 is driven to rotate. During the rotation of the second bevel gear 222, the first bevel gear 221 is driven, and at the same time, with the cooperation of the vertical rod 220, the other connecting shaft 150 rotates. Therefore, during the rotation of the two connecting shafts 150, the guide plate 135 is driven to rotate by the connecting sleeve 151. It should be noted that during the rotation, the scroll spring 170 is in a compressed state, and the ends of the two guide plates 135 are brought closer, so as to guide the air during the air intake process of the purifier body 110, limit the air intake opening, prevent large - scale blowing, and make the air blow towards the clean filter cloth 122.
[0051] Moreover, when the connecting rod 115 is rotating, the end of the abutting block 155 is engaged between several elastic blocks 162, so that the connecting rod 115 can drive the guide plate 135 to rotate. At this time, the end of the connecting block 160 contacts the connecting ring 153. As the rotating shaft 130 continuously rotates, the connecting shaft 150 is driven to continuously rotate. When the connecting shaft 150 drives the connecting block 160 to rotate and the end of the connecting block 160 is located above the reset groove 163, the inner wall of the connecting ring 153 no longer restricts the connecting block 160. At this time, the pulling spring 161 drives the abutting block 155 to descend into the air storage tank 154. Therefore, the gas pushes the connecting block 160, so that the end of the connecting block 160 reaches the inside of the reset groove 163, and the abutting block 155 disengages from the engagement with several elastic blocks 162. Thus, the purpose of the disengagement of the connecting sleeve 151 and the connecting shaft 150 is achieved. At the same time, the originally compressed scroll spring 170 drives the connecting sleeve 151 to reset, so the reset of the guide plate 135 is achieved. As the rotating shaft 130 rotates continuously, the reciprocating rotation effect of the guide plate 135 is achieved.
[0052] The air storage airbag 134 is set as a corrugated airbag. A connecting pipe 180 is installed on the side of the air storage airbag 134. The connecting pipe 180 communicates with the cleaning rod 132. Several air blowing ports 181 are installed on the bottom side of the cleaning rod 132. A first one - way valve 182 is installed on the connecting pipe 180.
[0053] See Figure 9In a specific implementation, when the guide plate 135 rotates, the side of the guide plate 135 presses the air storage bag 134, and the gas inside the air storage bag 134 reaches the inside of the cleaning rod 132 through the connecting pipe 180. At the same time, the gas is blown from the inside of the cleaning rod 132 to the surface of the filter cloth 122, so that the dust on the surface of the filter cloth 122 falls into the inside of the placement frame 121. Therefore, the contaminated surface is cleaned during the rotation of the filter cloth 122. The guide plate 135 rotates back and forth during the rotation of the rotating shaft 130, thereby achieving continuous cleaning of the filter cloth 122.
[0054] During specific implementation, several prompt blocks 171 are installed on the surface of the filter cloth 122. The prompt blocks 171 are set as an arc surface. Several prompt blocks 171 are installed on the surface of the filter cloth 122 in a linear array. Several rotating shafts 130 are provided with prompt grooves 172. The prompt blocks 171 are engaged with the prompt grooves 172. It should be noted that in the process of rotating the rotating shaft 130, since the prompt block 171 is set as an arc surface, when the operator rotates the rotating rod 131 more forcefully, the prompt block 171 loses engagement with the prompt groove 172. When replacing the filter surface, the filter cloth 122 is rotated by the rotation of the rotating shaft 130, so that the prompt block 171 is engaged with the prompt groove 172. At the same time, when the rotating shaft 130 is continuously rotated, a certain amount of force is required because the prompt block 171 is engaged with the prompt groove 172, thereby prompting the operator that the annular surface is successful.
[0055] It should be noted that, when the rotating shaft 130 is rotated one round, the prompt block 171 is engaged with the prompt groove 172 , and the ends of the two guide plates 135 are close to each other.
[0056] In this embodiment, the connection shaft 150, the rotating shaft 130, the connecting sleeve 151, the air storage bag 134 and the guide plate 135 cooperate to clean the contaminated surface while replacing the filter surface. During the rotation of the rotating shaft 130, the connection shaft 150 is rotated by the cooperation of the pulley assembly 152. During the rotation of the connection shaft 150, the elastic block 162 and the resistance block 155 cooperate to drive the guide plate 135 to rotate. The ends of the two guide plates 135 are close to each other, so that the air inlet is restricted, avoiding large-scale blowing as much as possible, and the wind is blown to the clean filter cloth 122.
[0057] Moreover, through the cooperation of the elastic block 162, the abutting block 155, the connecting block 160 and the reset groove 163, when the rotating shaft 130 drives the connecting shaft 150 to rotate continuously, the end of the connecting block 160 reaches inside the reset groove 163, pulling the spring 161 to drive the abutting block 155 to descend into the air storage tank 154, achieving the purpose of disengaging the connecting sleeve 151 from the connecting shaft 150. And through the cooperation of the scroll spring 170, the reset of the guide plate 135 is realized. At the same time, as the rotating shaft 130 rotates continuously, the reciprocating rotation of the guide plate 135 is achieved. During the reciprocating rotation of the guide plate 135, the guide plate 135 continuously presses the air storage airbag 134. Therefore, the gas inside the air storage airbag 134 reaches inside the cleaning rod 132 through the connecting pipe 180, and at the same time, the gas is blown from inside the cleaning rod 132 to the surface of the filter cloth 122, so that the dust on the surface of the filter cloth 122 falls into the placement frame 121. Therefore, during the rotation of the filter cloth 122, the cleaning of the contaminated surface is realized, so that the filter cloth 122 is always in an efficient filtering state, continuously providing clean air and significantly improving the filtering efficiency.
[0058] Embodiment 3. The purpose of this embodiment is to promote the solution of the problem that since the rotation of the filter cloth 122 is carried out, the cleaning time is less, thus affecting the cleaning effect. This embodiment is an improvement made on the basis of Embodiment 2. Specifically, please refer to Figure 1 - Figure 10 , a rotating disk 190 is installed on the rotating shaft 130. There are two rotating disks 190. A connecting shaft 191 is installed between the two rotating disks 190. The connecting shaft 191 is eccentrically arranged between the two rotating disks 190. A push rod 192 is rotatably installed on the surface of the connecting shaft 191.
[0059] A piston block 193 is inserted and slidably installed inside the air storage cylinder 133. The end of the push rod 192 is connected to the piston block 193. A connecting pipe 194 is installed on the bottom side of the air storage cylinder 133. The connecting pipe 194 is connected to the cleaning rod 132. An air inlet 210 is opened on the bottom side of the air storage cylinder 133. A second one-way valve 211 is installed on the air inlet 210. The second one-way valve 211 is used to prevent the gas from flowing out of the air inlet 210. A third one-way valve 212 is installed on the connecting pipe 194. The third one-way valve 212 is used to prevent the problem of gas backflow.
[0060] See Figure 8, during specific implementation, when the rotating shaft 130 rotates, the rotating disk 190 drives the connecting shaft 191 to rotate. Therefore, during the rotation of the connecting shaft 191, the push rod 192 is driven to expand and contract. During the expansion and contraction of the push rod 192, the piston block 193 is driven to move. Therefore, the piston block 193 slides inside the air storage cylinder 133. And during the movement of the piston block 193, air enters through the air inlet 210 and exits through the connecting pipe 194, achieving the effect of supplying air to the cleaning pipe, strengthening the air pressure, and enabling the filter cloth 122 on the contaminated surface to be cleaned quickly and efficiently.
[0061] In this embodiment: Through the cooperation of the rotating disk 190, the connecting shaft 191, the push rod 192, the air storage cylinder 133, and the piston block 193, during the rotation of the rotating shaft 130, the connecting shaft 191 is used to drive the push rod 192 to expand and contract. And during the expansion and contraction process, the piston block 193 is driven to slide inside the air storage cylinder 133. During the sliding of the piston block 193, the effect of supplying air to the cleaning pipe is achieved. Therefore, the air pressure inside the cleaning pipe is further strengthened. Therefore, the strengthened air flow can prevent the filter cloth 122 from being blocked as much as possible, ensuring the smooth flow of air. It can not only maintain the high-efficiency filtering state of the filter cloth 122 but also extend its service life.
