Description

Technical Field

[0001] The invention relates to the field of air filter maintenance, in particular to an easy-to-maintain air filter. Background Art

[0002] An air filter is a device that captures dust through porous filter materials and purifies gases. It purifies low-dust air and sends it into the room to ensure the process requirements of clean rooms and the air cleanliness in general air-conditioned rooms. When the air filter is in use, it needs to be regularly maintained and fixedly installed to extend its service life.

[0003] For example, Chinese patent CN220758470U discloses an air filter that is easy to maintain. The air filter is divided into a base and an outer shell and two clamps are arranged on the base. The two clamps can automatically fit into two positioning holes on the outer shell under the action of springs to fix the outer shell to the base. Moreover, when the staff needs to maintain the filter body, the staff only needs to press two toggle plates to separate the outer shell from the base. This is not only simple to operate and quick to disassemble, but also realizes the feature of easy maintenance of the filter body.

[0004] For this structure, although the outer shell and the base can be quickly opened to maintain the air filter, the air filter is often filtered through a filter mesh. This structure can only maintain the air filter as a whole, but it is inconvenient to maintain the filter mesh. Therefore, we propose an easy-to-maintain air filter that can quickly maintain the filter mesh in the air filter to improve its filtering effect. Summary of the invention

[0005] The object of the present invention is to provide an easy-to-maintain air filter to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an easy-to-maintain air filter, comprising a shell, a base fixedly installed on the bottom of the shell, a supporting leg fixedly installed on the bottom of the base, an air outlet opened on the outer wall of the shell, a fan mechanism and a processing component arranged inside the shell, the processing component comprising a maintenance component arranged inside the shell, a closing component arranged above the maintenance component, and a replacement component arranged below the closing component.

[0007] According to the above technical scheme, the maintenance component includes a limit block fixedly installed on the inner wall of the shell, a pull plate is slidably provided on the outer wall of the limit block, a limit groove is provided on the outer wall of the pull plate, a fixed plate is fixedly installed on the side wall of the pull plate, a slide groove is provided on the outer wall of the fixed plate, a first spring is provided inside the slide groove, a slider is slidably provided on the inner wall of the slide groove, a slide frame is fixedly installed on the outer wall of the slider, a frame groove is provided on the inner wall of the slide frame, a first magnetic plate is fixedly installed on the inner wall of the frame groove, a second magnetic plate is slidably provided inside the frame groove, a clamping block is fixedly installed on the outer wall of the second magnetic plate, a filter plate is clamped on the inner side of the slide frame, a clamping groove is provided on the outer wall of the filter plate, and a handle is fixedly installed on the top surface of the pull plate.

[0008] According to the above technical solution, the closing component includes a strip groove opened on the inner wall of the shell, a second spring is arranged inside the strip groove, a strip plate is slidably arranged on the inner wall of the strip groove, an extrusion strip is fixedly installed on the outer wall of the strip plate, an air inlet plate is hingedly connected to the inner wall of the shell, a blocking column is fixedly installed on the outer wall of the air inlet plate, and an arc groove is opened on the inner wall of the shell.

[0009] According to the above technical solution, the replacement assembly includes a placement plate fixedly installed on the side wall of the pulling plate, a fixing block fixedly installed on the top surface of the placement plate, opposing threaded rods are sleeved inside the fixing block, a clamping plate is sleeved on the outer wall of the opposing threaded rods, a new filter plate is arranged on the top surface of the placement plate, and a limiting rod is arranged on one end of the clamping plate that slides away from the opposing threaded rod.

[0010] According to the above technical solution, the sliding block fixedly installed on the outer wall of the sliding frame is slidably arranged with the fixed plate opened on the outer wall of the limiting groove, and the outer wall of the sliding frame and the outer wall of the fixed plate are slidably arranged. Under their restriction, when the pull plate is pulled out of the shell, the sliding frame can be slid toward the outside of the shell, driving the filter plate clamped inside the sliding frame to slide accordingly, which is convenient for the operator to maintain the filter plate.

[0011] According to the above technical solution, one end of the first spring is fixedly installed on the inner wall of the slide groove close to the pull plate, and the end of the first spring away from the pull plate is fixedly installed on the outer wall of the slider. Under the action of the elasticity of the first spring, when the slide frame is not restricted by the inner wall of the shell, it will drive the filter plate clamped on the inner side of the slide frame to slide away from the pull plate, so that the filter plate is stepped, which is convenient for operators to maintain the filter plate.

[0012] According to the above technical solution, the first magnetic plate and the second magnetic plate magnetically repel each other, and the clamping block is arranged in an inclined surface. Under the restriction, the filter plate is pushed from the bottom of the slide frame into the inner side of the slide frame, so that the outer wall of the filter plate is in contact and squeezed with the inclined surface of the clamping block, and the second magnetic plate is pushed toward the first magnetic plate. When the clamping block is engaged with the clamping slot, the clamping block is engaged with the clamping slot under the action of the mutual repulsion between the first magnetic plate and the second magnetic plate, so as to achieve the effect of quick installation of the filter plate, so as to facilitate the operator to replace and maintain the filter plate.

[0013] According to the above technical solution, the outer wall of the extrusion strip is arranged in an arc surface, and there are two extrusion strips, which are symmetrically distributed with respect to the center line of the top surface of the shell. Under the arrangement of the arc surface of the extrusion strip, when the outer wall of the air inlet plate contacts it, the extrusion strip can be smoothly pushed into the strip groove, so that the extrusion strip is no longer clamped with the top surface of the air inlet plate.

[0014] According to the above technical solution, one end of the second spring is fixedly installed on the inner wall of the strip groove, and the end of the second spring away from the inner wall of the strip groove is fixedly installed on the outer wall of the strip plate. Under the elastic limitation of the second spring, when the air inlet plate is in a horizontal state, the second spring pushes the extrusion strip toward the outside of the strip groove, so that the extrusion strip slides and engages with the outer wall of the air inlet plate, thereby preventing the air inlet plate from opening when in use.

[0015] According to the above technical solution, the outer wall of the opposing threaded rod is threadedly sleeved with the inner thread of the clamping plate, and the clamping plate is slidably arranged with one end away from the opposing threaded rod and the outer wall of the limiting rod. Under the restriction of the limiting rod, when the opposing threaded rod rotates, it can drive the four clamping plates to be divided into two groups and move in opposite directions.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The easy-to-maintain air filter of the present invention is composed of a maintenance component as one of its components. When the air filter needs to be maintained, the handle is pulled to drive the pull plate to slide toward the outside of the shell. The limit grooves on the outer wall of the pull plate slide on the outer wall of the limit block fixedly installed on the inner wall of the shell. Under the restriction, the pull plate slides stably, and the fixed plate fixedly installed on the side wall of the pull plate drives the slide frame to slide accordingly. The filter plate clamped inside the slide frame slides toward the outside of the shell accordingly, and the outer wall of the fixed plate contacts and squeezes the air inlet plate. When the fixed plate completely slides out of the shell, the air inlet plate is not squeezed. Under the push of the squeezing bar, the air inlet plate is in a horizontal state, and the fixed plate at the lower end of the pull plate is placed On the top surface of the air inlet plate, the filter plate can be maintained at this time. When the sliding frame is no longer in contact with the inner wall of the shell, under the left and right of the first spring elasticity, the sliding block fixedly installed on the outer wall of the sliding frame is pushed away from the pull plate, so that the sliding block and the sliding groove opened on the outer wall of the fixed plate slide. Due to the different lengths of the sliding grooves, the sliding frame slides out of the inner side of the fixed plate in a step-by-step manner, which is convenient for the operator to maintain the filter plate clamped on the inner side of the sliding frame. When the filter plate is maintained, the sliding frame is pushed in the direction of the pull plate, and then the pull plate is pushed into the shell. Through the fan mechanism, the air outside the shell is sucked into the shell through the air inlet plate, and filtered through the maintained filter plate.

[0017] 2. The easy-to-maintain air filter of the present invention is composed of a maintenance component as one component. When the filter plate has been used for a long time and needs to be replaced, the filter plate is pushed upward so that the inner wall of the slot opened on the outer wall of the filter plate contacts and is squeezed with the inclined surface of the block, so that the block drives the second magnetic plate to slide into the frame slot to remove the filter plate. The new filter plate is packaged and unpacked, and the new filter plate is pushed from the bottom of the slide frame to the inside of the slide frame, and the outer wall of the new filter plate contacts and is squeezed with the inclined surface of the block. When the slot opened on the outer wall of the new filter plate is aligned with the block, the block is connected to the slot under the action of the mutual repulsion of magnetism between the first magnetic plate and the second magnetic plate, so as to achieve the effect of quick installation of the filter plate, so as to facilitate the operator to replace and maintain the filter plate.

[0018] 3. The easy-to-maintain air filter of the present invention is composed of a closed assembly as one component. When the air filter needs to be maintained, the handle is pulled to make the outer wall of the fixed plate fixedly installed on the side wall of the pull plate contact and push the air inlet plate, so that the air inlet plate deflects with the hinged part with the inner wall of the shell as the rotation center, and the outer wall of the air inlet plate contacts and squeezes the arc surface of the extrusion strip, so that the extrusion strip slides into the inside of the strip groove, and the second spring is compressed by the strip plate to open the air inlet plate to a vertical state. At this time, the filter plate arranged on the outer wall of the pull plate can be pulled out of the shell, and the operator can perform maintenance work on the filter plate. When the maintenance is completed, The pull plate is pushed toward the inside of the shell, and the air inlet plate is closed. The blocking column fixedly installed at its end makes the two air inlet plates in a horizontal state under the restriction of the arc groove. The gaps opened on the outer walls of the air inlet plates can allow outside air to enter the shell for filtering. When the air inlet plates are in a horizontal state, the extrusion strips are not squeezed. Under the action of the elasticity of the second spring, the extrusion strips and the top surface of the air inlet plates are slidably engaged to restrict the air inlet plates, thereby preventing the air inlet plates from being opened to affect safety when the air filter is in use. This structure does not require the operator to use tools to open the air inlet plates to maintain the air filter, thereby improving the convenience of maintenance.

[0019] 4. The easy-to-maintain air filter of the present invention is composed of a replacement component as one of its components. When the filter plate has been used for a long time and needs to be replaced, the handle is pulled to lift the pull plate from the shell, and the opposing threaded rods are rotated. Since the clamping plate is away from one end of the opposing threaded rod and slides with the outer wall of the limit rod, under its restriction, the opposing threaded rods can drive the clamping plate to no longer clamp the new filter plate. At this time, the new filter plate packaging is unpacked and the new filter plate is replaced with the filter plate. This structure can place the brand new filter plate inside the shell for storage, which is convenient for the operator to quickly replace the filter plate and avoid the loss of the new filter plate when it is stored independently, making the air filter maintenance more convenient.

[0023] In this embodiment, when the air filter needs to be maintained, the handle 619 is pulled, which drives the pull plate 612 to slide toward the outside of the shell 1, and the limit groove 613 provided on the outer wall of the pull plate 612 slides on the outer wall of the limit block 611 fixedly installed on the inner wall of the shell 1. Under its restriction, the pull plate 612 slides stably, and the fixed plate 614 fixedly installed on the side wall of the pull plate 612 drives the slide frame 618 to slide accordingly, and the filter plate 624 clamped inside the slide frame 618 slides toward the outside of the shell 1 accordingly, and the outer wall of the fixed plate 614 contacts and squeezes the air inlet plate 637. When the fixed plate 614 slides out of the shell 1 completely, the air inlet The air plate 637 is not squeezed, and under the push of the squeezing strip 634, the air inlet plate 637 is in a horizontal state, and the fixed plate 614 at the lower end of the pull plate 612 is placed on the top surface of the air inlet plate 637. At this time, the filter plate 624 can be maintained. When the slide frame 618 is no longer in contact with the inner wall of the shell 1, under the elasticity of the first spring 616, the slider 617 fixedly installed on the outer wall of the slide frame 618 is pushed away from the pull plate 612, so that the slider 617 slides with the slide groove 615 opened on the outer wall of the fixed plate 614.

When the slot 625 opened on the outer wall of the new filter plate 645 is aligned with the block 623, under the effect of the mutual magnetic repulsion between the first magnetic plate 621 and the second magnetic plate 622, the block 623 is clamped with the slot 625 to achieve the effect of quick installation of the filter plate 624, so as to facilitate the operator to replace and maintain the filter plate 624. Example

[0024] A preferred embodiment of an easy-to-maintain air filter provided by the present invention is as follows: Figures 1 to 9As shown: the closing component 63 includes a strip groove 631 opened on the inner wall of the shell 1, a second spring 632 is arranged inside the strip groove 631, a strip plate 633 is slidably arranged on the inner wall of the strip groove 631, an extrusion strip 634 is fixedly installed on the outer wall of the strip plate 633, an air inlet plate 637 is hingedly connected to the inner wall of the shell 1, a blocking column 636 is fixedly installed on the outer wall of the air inlet plate 637, and an arc groove 635 is opened on the inner wall of the shell 1.

[0025] In this embodiment, when the air filter needs to be maintained, the handle 619 is pulled to make the outer wall of the fixed plate 614 fixedly installed on the side wall of the pull plate 612 contact and push the air inlet plate 637, so that the air inlet plate 637 deflects with the hinged part with the inner wall of the shell 1 as the rotation center, and the outer wall of the air inlet plate 637 contacts and squeezes the arc surface of the extrusion strip 634, so that the extrusion strip 634 slides into the inside of the strip groove 631, and the second spring 632 is compressed by the strip plate 633, so that the air inlet plate 637 is opened to a vertical state. At this time, the filter plate 624 set on the outer wall of the pull plate 612 can be pulled out of the shell 1, and the operator can perform maintenance work on the filter plate 624. When the maintenance is completed, the pull plate 612 is pulled toward the shell 1. Pushed internally, the air inlet plate 637 is closed, and the blocking column 636 fixedly installed at its end is restricted by the arc groove 635, so that the two air inlet plates 637 are in a horizontal state. The gaps on the outer walls of the air inlet plates 637 can allow outside air to enter the shell 1 for filtering. When the air inlet plates 637 are in a horizontal state, the extrusion strip 634 is not squeezed. Under the elastic action of the second spring 632, the extrusion strip 634 is slidably engaged with the top surface of the air inlet plate 637 to restrict the air inlet plate 637, thereby preventing the air inlet plate 637 from opening and affecting safety when the air filter is in use. This structure does not require the operator to use tools to open the air inlet plate 637 to maintain the air filter, thereby improving the convenience of maintenance. Example

[0026] A preferred embodiment of an easy-to-maintain air filter provided by the present invention is as follows: Figures 1 to 9 As shown: the replacement component 64 includes a placement plate 641 fixedly installed on the side wall of the pulling plate 612, a fixing block 642 is fixedly installed on the top surface of the placement plate 641, an opposing threaded rod 643 is sleeved inside the fixing block 642, a clamping plate 644 is sleeved on the outer wall of the opposing threaded rod 643, a new filter plate 645 is arranged on the top surface of the placement plate 641, and a limiting rod 646 is arranged on the end of the clamping plate 644 that is slid away from the opposing threaded rod 643.

[0027] In this embodiment, when the filter plate 624 has been used for a long time and needs to be replaced, the handle 619 is pulled to lift the pull plate 612 from the shell 1, and the opposing threaded rod 643 is rotated. Since the clamping plate 644 is away from one end of the opposing threaded rod 643 and is slidably arranged on the outer wall of the limit rod 646, under its restriction, the opposing threaded rod 643 can drive the clamping plate 644 to no longer clamp the new filter plate 645. At this time, the new filter plate 645 is unpacked and replaced with the new filter plate 645. This structure can place the brand new filter plate 645 inside the shell 1 for storage, which is convenient for the operator to quickly replace the filter plate 624 and avoid the loss of the new filter plate 645 when it is stored independently, making the air filter maintenance more convenient.

[0028] Among them, the slider 617 fixedly installed on the outer wall of the sliding frame 618 is slidably arranged with the fixed plate 614 opened on the outer wall of the limiting groove 613, and the outer wall of the sliding frame 618 and the outer wall of the fixed plate 614 are slidably arranged. Under their restriction, when the pulling plate 612 can be pulled out of the shell 1, the sliding frame 618 can be slid toward the outside of the shell 1, driving the filter plate 624 clamped inside the sliding frame 618 to slide accordingly, which is convenient for the operator to maintain the filter plate 624.

[0029] Among them, one end of the first spring 616 is fixedly installed on the inner wall of the slide groove 615 close to the pull plate 612, and the end of the first spring 616 away from the pull plate 612 is fixedly installed on the outer wall of the slider 617. Under the elastic action of the first spring 616, when the slide frame 618 is not restricted by the inner wall of the shell 1, it will drive the filter plate 624 clamped on the inner side of the slide frame 618 to slide away from the pull plate 612, so that the filter plate 624 is stepped, which is convenient for the operator to maintain the filter plate 624.

[0030] Among them, the first magnetic plate 621 and the second magnetic plate 622 magnetically repel each other, and the block 623 is set at an inclined surface. Under the restriction, the filter plate 624 is pushed from the bottom of the slide frame 618 into the inner side of the slide frame 618, so that the outer wall of the filter plate 624 is in contact and squeezed with the inclined surface of the block 623, and the second magnetic plate 622 is pushed toward the first magnetic plate 621. When the block 623 is engaged with the slot 625, under the effect of the mutual magnetic repulsion between the first magnetic plate 621 and the second magnetic plate 622, the block 623 is engaged with the slot 625, so as to achieve the effect of quick installation of the filter plate 624, so as to facilitate the operator to replace and maintain the filter plate 624.

[0031] Among them, the outer wall of the extrusion strip 634 is set in an arc surface, and there are two extrusion strips 634, which are symmetrically distributed with the center line of the top surface of the shell 1. Under the setting of the arc surface of the extrusion strip 634, when the outer wall of the air inlet plate 637 contacts it, the extrusion strip 634 can be smoothly pushed into the strip groove 631, so that the extrusion strip 634 is no longer clamped with the top surface of the air inlet plate 637.

[0032] Among them, one end of the second spring 632 is fixedly installed on the inner wall of the strip groove 631, and the end of the second spring 632 away from the inner wall of the strip groove 631 is fixedly installed on the outer wall of the strip plate 633. Under the elastic limitation of the second spring 632, when the air inlet plate 637 is in a horizontal state, the second spring 632 pushes the extrusion strip 634 toward the outside of the strip groove 631, so that the extrusion strip 634 and the outer wall of the air inlet plate 637 are slidably engaged, thereby preventing the air inlet plate 637 from opening when in use.

[0033] Among them, the outer wall of the opposing threaded rod 643 is threadedly sleeved with the internal thread of the clamping plate 644, and one end of the clamping plate 644 away from the opposing threaded rod 643 is slidably set with the outer wall of the limiting rod 646. Under the restriction of the limiting rod 646, when the opposing threaded rod 643 rotates, it can drive the four clamping plates 644 to be divided into two groups and move in opposite directions.
