Description

Technical Field

[0001] The invention relates to the technical field of purifier filter elements, in particular to an air purifier filter element which is easy to disassemble and assemble. Background Art

[0002] Air purifier filters are the core components of air purification technology. Their function is to remove particulate matter, harmful gases, allergens, bacteria, viruses and other pollutants in the air through physical adsorption, chemical decomposition or biological filtration, thereby improving indoor air quality. With the acceleration of urbanization and the increase in industrial activities, air pollution is becoming more and more serious, and the types and concentrations of pollutants in indoor air are also increasing. Therefore, the demand for efficient and multifunctional air purifier filters is rising.

[0003] At present, the folding design commonly seen in air purifier filter elements, although it seems that the filter paper is folded into a multi-layer structure, is actually still a single-layer material. However, the physical structure of the single-layer filter paper determines that its ability to capture large-area pollutants is limited. For those air purifiers that must rely on physical filtration, when the particles captured on the filter paper accumulate to a certain extent, the filtration efficiency will drop significantly, which may cause the indoor air quality to deteriorate. Therefore, it does not meet the existing needs. In this regard, we propose an air purifier filter element that is easy to disassemble and assemble. Summary of the invention

[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 matching the filter cloth with a plurality of rotating shafts and winding the filter cloth around a plurality of rotating shafts. This not only significantly increases the effective surface area of ​​the filter cloth, but also increases the contact time and efficiency between the air and the filter material through the multi-faceted tortuous paths, thereby further improving the air purification effect.

[0021] Moreover, 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 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 torque 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 group, and 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, and the ends of the two guide plates are close to each other, so that the air inlet is restricted, and a large range of wind blowing is avoided as much as possible, so that the wind blows to the clean filter cloth;

[0023] Moreover, through the cooperation of the elastic block, the resistance block, the connecting block and the reset groove, when 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 realizing the purpose of disengaging the connecting sleeve from the connecting shaft, and the reset of the guide plate is realized through the cooperation of the volute spring. At the same time, with the continuous rotation of the rotating shaft, the reciprocating rotation effect of the guide plate is realized. During the reciprocating rotation of the guide plate, the guide plate continuously presses the air storage airbag, so that the gas inside the air storage airbag 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, during the rotation of 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 which is easy to disassemble and assemble, cooperates with a rotating disk, a connecting shaft, a pushing rod, an air storage cylinder and a piston block. During the rotation of the rotating shaft, the pushing rod is driven by the connecting shaft to extend and retract, and during the extension and retraction process, the piston block is driven to slide inside the air storage cylinder. During the sliding process of the piston block, the effect of supplying air to the cleaning pipe is achieved, thereby further enhancing the pressure of the gas inside the cleaning pipe. Therefore, the enhanced airflow can prevent the filter cloth from being blocked as much as possible, ensure smooth air circulation, not only maintain the efficient filtering state of the filter cloth, but also extend its service life.

DETAILED DESCRIPTION

[0036] 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.

[0037] Embodiment 1: This embodiment is intended to promote the solution of the common folding design in air purifier filter elements. 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 that its ability to capture large-area pollutants is limited. For those air purifiers that must rely on physical filtering, when the particles captured on the filter paper accumulate to a certain extent, the filtration efficiency will drop significantly, which may cause the indoor air quality to deteriorate. Please refer to Figure 1 - Fig.10, an air purifier filter element that is easy to disassemble and assemble, comprising a purifier body 110 and a filter element body 120 movably mounted on the purifier body 110, a placement seat 111 movably mounted on the purifier body 110, the filter element body 120 is mounted inside the placement seat 111, the filter element body 120 comprises a placement frame 121 and a filter cloth 122, a plurality of rotating shafts 130 are mounted inside the placement frame 121, the filter cloth 122 is arranged on the plurality 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 mounted 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 mounted inside the placement frame 121, and a guide plate 135 for pressing the air storage airbag 134 is mounted 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 rib 141 is installed inside the rotating shaft 130 , and one end of the rotating rod 131 is movably inserted into the placement frame 121 , the placement seat 111 and the purifier body 110 .

[0039] See Figure 1 , Figure 2 and Figure 3 In a specific implementation, the filter cloth 122 is wound around a plurality of rotating shafts 130 so that the filter cloth 122 can be folded into a plurality of surfaces, and the folded surfaces are arranged in parallel. When air passes through this complex filter cloth 122 structure, it needs to pass through a plurality of folded surfaces, thereby increasing the path length of contact with the filter cloth 122. Since the air must pass through the filter cloth 122 on a plurality of surfaces, the contact time and contact area are increased, thereby significantly improving the filtration efficiency, and being able to more effectively capture fine particles and pollutants.

[0040] A placement groove 112 for placing the filter element body 120 is provided inside the placement seat 111, a placement plate 113 is installed inside the placement groove 112, a push 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 rotatably matched with the shell of the purifier body 110, and a torsion spring 116 is installed between the connecting rod 115 and the shell 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 forced to expand; when the placement seat 111 is no longer controlled, the torsion spring 116 is reset and drives the placement seat 111 back to the inside of the purifier body 110.

[0041] See Figure 1 , Figure 2 and Figure 3In 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 so that one end of the placement seat 111 is away from the purifier body 110. In this process, the originally compressed push spring 114 releases its elastic force. Under the elastic force of the push spring 114, the placement plate 113 moves upward and lifts the filter element body 120 placed on its upper side at the same time, 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 the filter element body 120 is replaced, the placement seat 111 is released. During this process, the placement seat 111 is driven to reset through the torque of the torsion spring 116. At the same time, the filter element body 120 and the end of the rotating rod 131 are arranged in an arc shape, so 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, so that the placement seat 111 is successfully reset.

[0043] In this embodiment: by cooperating with the filter cloth 122 and a plurality of rotating shafts 130, by winding the filter cloth 122 around a plurality of rotating shafts 130, a tortuous multi-faceted structure is formed, which not only significantly increases the effective surface area of ​​the filter cloth 122, but also increases the contact time and efficiency between the air and the filter material through the multi-faceted tortuous paths, thereby 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, one end of the placement seat 111 is pulled so that the top of the placement seat 111 is away from the purifier body 110. In 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 lifts up the filter element body 120 placed on its upper side. Therefore, the upper end of the filter element body 120 is higher than the height of the placement seat 111, making the filter element easier 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 the filter element body 120 is replaced, the placement seat 111 is released. Through the torque of the torsion spring 116, the placement seat 111 can automatically return to its position without the need for manual adjustment by the user, thus saving time.

[0045] Embodiment 2: This embodiment is intended to promote the solution of the problem that since the filter cloth 122 is provided with multiple surfaces, the surface on the rear side of the filter cloth 122 is relatively clean and can be reused, but when the filter surface is replaced, the polluted surface will return to the rear side of the clean surface, and the dust on the polluted surface will affect the ventilation during the air intake process. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 9 A groove 142 is provided on the rotating rod 131, and the rib 141 is slidably fitted in the groove 142. Through the cooperation between the rib 141 and the groove 142, when the rotating rod 131 is rotated, one of the rotating shafts 130 can be driven to rotate through the restriction of the rib 141.

[0046] See Figure 4 In a 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, and the rotating rod 131 uses the cooperation of the convex rib 141 and the groove 142 to drive one of the rotating shafts 130 to rotate; at the same time, the filter cloth 122 is evenly wound on multiple rotating shafts 130 to form a continuous annular structure, and when one of the rotating shafts 130 rotates, it can drive the entire filter cloth 122 to move, thereby realizing the surface changing of the filter cloth 122. The surface changing 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 filtration efficiency due to blockage of a single surface.

[0047] A vertical rod 220 is rotatably mounted inside the placement frame 121 , first bevel gears 221 are mounted at both ends of the vertical rod 220 , and second bevel gears 222 are mounted on the two connecting shafts 150 , and the first bevel gear 221 meshes with the second bevel gear 222 .

[0048] The placing frame 121 is symmetrically provided with connecting shafts 150, and the surface gaps of the two connecting shafts 150 are sleeved with connecting sleeves 151, the guide plate 135 is installed on the connecting sleeves 151, a pulley set 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 placing frame 121, an air storage groove 154 is opened inside the connecting shaft 150, a resistance block 155 is movably installed at one end of the air storage groove 154, a connecting block 160 is movably installed at the other end of the air storage groove 154, and a pulling spring 161 is installed between the resistance block 155 and the air storage groove 154.

[0049] A plurality of elastic blocks 162 are installed inside the connecting sleeve 151. The elastic blocks 162 are set as rubber blocks or silicone blocks. The elastic blocks 162 are used to limit the interference blocks 155. When the interference blocks 155 are engaged between every two elastic blocks 162, the connecting sleeve 151 will be driven to rotate during the rotation of the connecting shaft 150. The plurality of elastic blocks 162 are installed in a ring array inside the connecting sleeve 151. A reset groove 163 is opened inside the connecting ring 153. The reset groove 163 is set as an arc 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 guide the plate 135 to reset.

[0050] See Figure 4 , Figure 5 , Figure 6 and Figure 7In a specific implementation, during the rotation of the rotating shaft 130, the pulley set 152 cooperates to make one of the connecting shafts 150 rotate, and during the rotation of one connecting shaft 150, the second bevel gear 222 is driven to rotate, and during the rotation of the second bevel gear 222, the first bevel gear 221 is driven, and at the same time, the cooperation of the vertical rod 220 is used to rotate the other connecting shaft 150. Therefore, during the rotation of the two connecting shafts 150, the connecting sleeve 151 is used to drive the guide plate 135 to rotate. It should be noted that during the rotation, the volute spring 170 is in a compressed state, and the ends of the two guide plates 135 are close to each other, so that the wind is guided during the process of the purifier body 110 taking in air, so that the air inlet is restricted, and the air will not blow over a large range, so that the wind blows to the clean filter cloth 122.

[0051] Moreover, when the connecting rod 115 is rotating, the end of the abutment block 155 is engaged between the plurality of 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 is in contact with the connecting ring 153. As the rotating shaft 130 rotates continuously, the connecting shaft 150 is driven to rotate continuously. When the connecting shaft 150 drives the connecting block 160 to rotate and the end of the connecting block 160 is located on the upper side of the reset groove 163, the inner wall of the connecting ring 153 no longer restricts the connecting block 160. At this time, the elastic block 162 is pulled. The spring 161 drives the resistance block 155 to descend into the gas storage tank 154, so that 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 resistance block 155 disengages from the engagement with the plurality of elastic blocks 162, thereby achieving the purpose of disengaging the connecting sleeve 151 from the connecting shaft 150. At the same time, the originally compressed volute spring 170 drives the connecting sleeve 151 to reset, thereby achieving the reset of the guide plate 135. As the rotating shaft 130 is continuously rotated, the reciprocating rotation effect of the guide plate 135 is achieved.

[0052] The air storage bag 134 is configured as a corrugated air bag, and a connecting pipe 180 is installed on the side of the air storage bag 134 . The connecting pipe 180 is communicated with the cleaning rod 132 . A plurality of blowing ports 181 are installed on the bottom side of the cleaning rod 132 , and a first one-way valve 182 is installed on the connecting pipe 180 .

[0053] See Fig. 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 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, so that the filter cloth 122 is continuously cleaned.

[0054] During specific implementation, a plurality of prompt blocks 171 are installed on the surface of the filter cloth 122, and the prompt blocks 171 are set to an arc surface. The plurality of prompt blocks 171 are installed on the surface of the filter cloth 122 in a linear array. Prompt grooves 172 are provided on the plurality of rotating shafts 130, and 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 to 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 driven to rotate 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: through the cooperation of the connecting shaft 150, the rotating shaft 130, the connecting sleeve 151, the air storage bag 134 and the guide plate 135, the contaminated surface can be cleaned while the filter surface is replaced; during the rotation of the rotating shaft 130, the connecting shaft 150 is rotated by the cooperation of the pulley group 152, and during the rotation of the connecting shaft 150, the guide plate 135 is driven to rotate by the cooperation of the elastic block 162 and the abutment block 155, and the ends of the two guide plates 135 are close to each other, so that the air inlet is restricted, and a large range of wind blowing is avoided as much as possible, so that the wind blows to the clean filter cloth 122;

[0057] Moreover, through the cooperation of the elastic block 162, the abutment 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 the inside of the reset groove 163, and the pulling spring 161 drives the abutment block 155 to descend into the air storage tank 154, so that the purpose of disengaging the connecting sleeve 151 from the connecting shaft 150 is achieved, and the reset of the guide plate 135 is achieved through the cooperation of the volute spring 170, and at the same time, as the rotating shaft 130 is continuously rotated, the reciprocating rotation of the guide plate 135 is achieved. In the process of reciprocating rotation of the guide plate 135, the guide plate 135 continuously presses the air storage bag 134, so that the gas inside the air storage bag 134 reaches the inside of the cleaning rod 132 through the connecting pipe 180, and 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 placement frame 121. Therefore, during the rotation of the filter cloth 122, the contaminated surface is cleaned, so that the filter cloth 122 is always in a high-efficiency filtering state, continuously providing clean air, and significantly improving the filtering efficiency.

[0058] Embodiment 3: This embodiment is intended to promote the solution of the problem that the filter cloth 122 is rotated, so the cleaning time is also short, thus affecting the cleaning effect. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1 - Fig.10 A rotating disk 190 is installed on the rotating shaft 130, and two rotating disks 190 are provided. 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, and a pushing rod 192 is rotatably installed on the surface of the connecting shaft 191.

[0059] A piston block 193 is slidably installed inside the air cylinder 133, and 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 cylinder 133, and the connecting pipe 194 is connected to the cleaning rod 132. An air inlet 210 is opened on the bottom side of the air cylinder 133, and a second one-way valve 211 is installed on the air inlet 210. The second one-way valve 211 is used to prevent gas from flowing out of the air inlet 210. A third one-way valve 212 is installed on the connecting pipe 194, and the third one-way valve 212 is used to prevent the problem of gas reflux.

[0060] See Figure 8In a specific implementation, when the rotating shaft 130 rotates, the rotating disk 190 drives the connecting shaft 191 to rotate, so that the push rod 192 is driven to extend and retract during the rotation of the connecting shaft 191, and the piston block 193 is driven to move during the extension and retraction of the push rod 192. Therefore, the piston block 193 is inserted and slid inside the air storage cylinder 133, and in the process of the movement of the piston block 193, air is taken in through the air inlet 210 and the connecting pipe 194 is used to discharge air, thereby achieving the effect of supplying air to the cleaning pipe, increasing the gas pressure, and making it possible to quickly and efficiently clean the filter cloth 122 on the contaminated surface.

[0061] In the present embodiment: through the cooperation of the rotating disk 190, the connecting shaft 191, the pushing rod 192, the air cylinder 133 and the piston block 193, during the rotation of the rotating shaft 130, the connecting shaft 191 is used to drive the pushing rod 192 to extend and retract, and during the extension and retraction process, the piston block 193 is driven to slide inside the air cylinder 133, and the effect of supplying air to the cleaning pipe is achieved during the sliding of the piston block 193, thereby further enhancing the pressure of the gas inside the cleaning pipe. Therefore, the enhanced airflow can prevent the filter cloth 122 from being blocked as much as possible, ensure smooth air circulation, not only maintain the efficient filtering state of the filter cloth 122, but also extend its service life.
