Description

Technical Field

[0001] The present invention relates to the field of air filter maintenance, and particularly to an easily maintainable air filter. Background Art

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

[0003] For example, an easily maintainable air filter disclosed in Chinese Patent CN220758470U divides the air filter into a base and a housing, and two clamping heads are arranged on the base. Under the action of springs, the two clamping heads can automatically snap into two positioning holes on the housing to fix the housing 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 housing from the base, which is not only simple to operate but also quick to disassemble, realizing the feature that the filter body is easy to maintain.

[0004] For this structure, although the housing can be quickly opened from the base to maintain the air filter, the air filter often filters through a filter screen. This structure can only maintain the air filter as a whole and is inconvenient for maintaining the filter screen. Therefore, we propose an easily maintainable air filter that can quickly maintain the filter screen in the air filter to improve its filtering effect. Summary of the Invention

[0005] The purpose of the present invention is to provide an easily maintainable air filter to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: An easily maintainable air filter, including a housing, a base is fixedly installed at the bottom of the housing, support legs are fixedly installed at the bottom of the base, an air outlet is opened on the outer wall of the housing, a fan mechanism is arranged inside the housing, and a processing component is arranged inside the housing. The processing component includes a maintenance component arranged inside the housing, a closing component is arranged above the maintenance component, and a replacement component is arranged below the closing component.

[0007] According to the above technical solution, the maintenance component includes a limit block fixedly installed on the inner wall of the housing. A pull plate is slidably arranged on the outer wall of the limit block. A limit groove is formed on the outer wall of the pull plate. A fixing plate is fixedly installed on the side wall of the pull plate. A sliding groove is formed on the outer wall of the fixing plate. A first spring is arranged inside the sliding groove. A slider is slidably arranged on the inner wall of the sliding groove. A sliding frame is fixedly installed on the outer wall of the slider. A frame groove is formed on the inner wall of the sliding frame. A first magnetic plate is fixedly installed on the inner wall of the frame groove. A second magnetic plate is slidably arranged inside the frame groove. A clamping block is fixedly installed on the outer wall of the second magnetic plate. A filter plate is clamped inside the sliding frame. A clamping groove is formed on the outer wall of the filter plate. 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 formed on the inner wall of the housing. 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 housing. A blocking post is fixedly installed on the outer wall of the air inlet plate. An arc groove is formed on the inner wall of the housing.

[0009] According to the above technical solution, the replacement component includes a placement plate fixedly installed on the side wall of the pull plate. A fixing block is fixedly installed on the top surface of the placement plate. An opposed threaded rod is sleeved inside the fixing block. A clamping plate is sleeved on the outer wall of the opposed threaded rod. A new filter plate is arranged on the top surface of the placement plate. A limit rod is slidably arranged at one end of the clamping plate away from the opposed threaded rod.

[0010] According to the above technical solution, the slider fixedly installed on the outer wall of the sliding frame is slidably arranged with the fixing plate formed on the outer wall of the limit groove. The outer wall of the sliding frame is slidably arranged with the outer wall of the fixing plate. Under its restriction, when the pull plate is pulled out of the interior of the housing, the sliding frame can be slid in the direction of the outside of the housing, driving the filter plate clamped inside the sliding frame to slide accordingly, facilitating 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 sliding groove close to the pull plate side, 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 sliding frame is not restricted by the inner wall of the housing, it will drive the filter plate clamped inside the sliding frame to slide in the direction away from the pull plate, making the filter plate in a stepped shape, facilitating the operator to maintain the filter plate.

[0012] According to the above technical solution, the first magnetic plate and the second magnetic plate are magnetically repellent to each other. The clamping block is arranged in an inclined plane. Under the restriction, the filter plate is pushed into the inside of the sliding frame from the bottom of the sliding frame, so that the outer wall of the filter plate contacts and presses against the inclined plane of the clamping block, pushing the second magnetic plate towards the first magnetic plate. When the clamping block is clamped with the clamping groove, under the action of the magnetic repulsion between the first magnetic plate and the second magnetic plate, the clamping block is clamped with the clamping groove to achieve the effect of quickly installing the filter plate, facilitating 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 shape. There are two extrusion strips, which are symmetrically distributed along the center line of the top surface of the housing. With the arc-shaped arrangement of the extrusion strips, when the outer wall of the air inlet plate contacts them, the extrusion strips can be smoothly pushed into the strip grooves, so that the extrusion strips no longer engage 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 other 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 restriction of the second spring, when the air inlet plate is in a horizontal state, the second spring pushes the extrusion strip towards the outside of the strip groove, so that the extrusion strip is slidably engaged with the outer wall of the air inlet plate, preventing the air inlet plate from opening during use.

[0015] According to the above technical solution, the outer wall of the opposed threaded rod is threadedly sleeved inside the clamping plate, and one end of the clamping plate away from the opposed threaded rod is slidably arranged on the outer wall of the limiting rod. Under the restriction of the limiting rod, when the opposed threaded rod rotates, it can drive the four clamping plates to be divided into two groups to move towards or away from each other.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0017] 1. The easy-to-maintain air filter of the present invention has a maintenance component as one of its parts. When the air filter needs to be maintained, pull the handle, which drives the pull plate to slide towards the outside of the housing. The limiting groove formed on the outer wall of the pull plate slides on the outer wall of the limiting block fixedly installed on the inner wall of the housing. Under its restriction, the pull plate slides stably. The fixing plate fixedly installed on the side wall of the pull plate drives the sliding frame to slide accordingly, and the filter plate clamped inside the sliding frame slides towards the outside of the housing. The outer wall of the fixing plate contacts and presses the air inlet plate. When the fixing plate completely slides out of the inside of the housing, the air inlet plate is no longer pressed. Under the push of the extrusion strip, the air inlet plate is in a horizontal state. Place the fixing plate at the lowermost end of the pull plate on the top surface of the air inlet plate. At this time, the maintenance work of the filter plate can be carried out. When the sliding frame no longer contacts and presses the inner wall of the housing, under the influence of the elasticity of the first spring, the slider fixedly installed on the outer wall of the sliding frame is pushed away from the pull plate, so that the slider slides in the chute formed on the outer wall of the fixing plate. Since the lengths of the chutes are different, the sliding frame slides out of the inner side of the fixing plate in a stepped manner, facilitating the operator to maintain the filter plate clamped inside the sliding frame. After the maintenance of the filter plate is completed, push the sliding frame towards the pull plate, and then push the pull plate towards the inside of the housing. Through the fan mechanism, the air outside the housing is inhaled into the housing through the air inlet plate and filtered by the maintained filter plate.

[0018] 2. The easy-to-maintain air filter of the present invention has a maintenance component as a part thereof. 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 card slot opened on the outer wall of the filter plate contacts and squeezes the inclined surface of the card block, causing the card block to drive the second magnetic plate to slide into the frame slot to remove the filter plate. The package of the new filter plate is opened, and the new filter plate is pushed from the bottom of the sliding frame to the inside of the sliding frame. The outer wall of the new filter plate contacts and squeezes the inclined surface of the card block. When the card slot opened on the outer wall of the new filter plate is aligned with the card block, under the action of the magnetic repulsion between the first magnetic plate and the second magnetic plate, the card block and the card slot are clamped to achieve the effect of quickly installing the filter plate, facilitating the operator to replace and maintain the filter plate.

[0019] 3. The easy-to-maintain air filter of the present invention has a closing component as a part thereof. When the air filter needs to be maintained, the handle is pulled, so that the outer wall of the fixing plate fixedly installed on the side wall of the pull plate contacts and pushes the air inlet plate, causing the air inlet plate to deflect with the hinge at the inner wall of the housing as the rotation center, and the outer wall of the air inlet plate contacts and squeezes the arc surface of the extrusion strip, causing the extrusion strip to slide into the strip slot and compressing the second spring through the strip plate, so that the air inlet plate opens to a vertical state. At this time, the filter plate provided on the outer wall of the pull plate can be pulled out of the housing, and the operator can perform maintenance work on the filter plate. After the maintenance is completed, the pull plate is pushed into the housing, and the air inlet plate closes. The retaining post fixedly installed at its end is restricted by the arc slot, so that the two air inlet plates are in a horizontal state. The gap opened on the outer wall of the air inlet plate allows external air to enter the housing for filtering work. When the air inlet plate is in a horizontal state, the extrusion strip is not squeezed, and under the action of the elasticity of the second spring, the extrusion strip is slidably clamped with the top surface of the air inlet plate to limit the air inlet plate, avoiding the air inlet plate from opening during the use of the air filter and affecting safety. This structure does not require the operator to use tools to open the air inlet plate to maintain the air filter, improving the convenience of maintenance.

[0020] 4. The easy-to-maintain air filter of the present invention has a replacement component as a part thereof. When the filter plate has been used for a long time and needs to be replaced, the handle is pulled, the pull plate is lifted from the housing, and the opposing threaded rod is rotated. Since the end of the clamping plate away from the opposing threaded rod is slidably arranged on the outer wall of the limiting rod, under its restriction, the opposing threaded rod can drive the clamping plate to no longer clamp the new filter plate. At this time, the package of the new filter plate is opened, and the new filter plate is used to replace the filter plate. This structure can store the brand-new filter plate inside the housing, facilitating the operator to quickly replace the filter plate and avoiding the loss of the new filter plate when it is stored independently, making the maintenance of the air filter more convenient.

Detailed implementation manners

[0032] 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. Embodiment

[0033] A preferred embodiment of the easy-to-maintain air filter provided by the present invention is as follows Figures 1 to 9 shown: An easy-to-maintain air filter includes a housing 1;

[0034] A base 2 is fixedly installed at the bottom of the housing 1;

[0035] Support legs 4 are fixedly installed at the bottom of the base 2;

[0036] An air outlet 3 is provided on the outer wall of the housing 1;

[0037] A fan mechanism 5 is arranged inside the housing 1;

[0038] And a processing component 6 arranged inside the housing 1. The processing component 6 includes a maintenance component 61 arranged inside the housing 1. The maintenance component 61 includes a limit block 611 fixedly installed on the inner wall of the housing 1. A pull plate 612 is slidably arranged on the outer wall of the limit block 611. A limit groove 613 is provided on the outer wall of the pull plate 612. A fixing plate 614 is fixedly installed on the side wall of the pull plate 612. A chute 615 is provided on the outer wall of the fixing plate 614. A first spring 616 is arranged inside the chute 615. A slider 617 is slidably arranged on the inner wall of the chute 615. A sliding frame 618 is fixedly installed on the outer wall of the slider 617. A frame groove 620 is provided on the inner wall of the sliding frame 618. A first magnetic plate 621 is fixedly installed on the inner wall of the frame groove 620. A second magnetic plate 622 is slidably arranged inside the frame groove 620. A clamping block 623 is fixedly installed on the outer wall of the second magnetic plate 622. A filter plate 624 is clamped inside the sliding frame 618. A clamping groove 625 is provided on the outer wall of the filter plate 624. A handle 619 is fixedly installed on the top surface of the pull plate 612.

[0039] In this embodiment, when maintenance of the air filter is required, the handle 619 is pulled, which drives the pull plate 612 to slide outward in the direction of the outside of the housing 1. The limiting groove 613 formed on the outer wall of the pull plate 612 slides on the outer wall of the limiting block 611 fixedly installed on the inner wall of the housing 1. Under its restriction, the pull plate 612 slides stably. The fixed plate 614 fixedly installed on the side wall of the pull plate 612 drives the sliding frame 618 to slide accordingly. The filter plate 624 clamped inside the sliding frame 618 slides outward in the direction of the outside of the housing 1. The outer wall of the fixed plate 614 contacts and presses against the air inlet plate 637. When the fixed plate 614 completely slides out of the inside of the housing 1, the air inlet plate 637 is not pressed. Under the push of the pressing strip 634, the air inlet plate 637 is in a horizontal state. The fixed plate 614 at the lowermost end of the pull plate 612 is placed on the top surface of the air inlet plate 637. At this time, maintenance work can be carried out on the filter plate 624. When the sliding frame 618 no longer contacts and presses against the inner wall of the housing 1, under the elastic action of the first spring 616, the slider 617 fixedly installed on the outer wall of the sliding frame 618 is pushed in the direction away from the pull plate 612, so that the slider 617 slides in the chute 615 formed on the outer wall of the fixed plate 614. Since the lengths of the chutes 615 are different, the sliding frame 618 slides out of the inner side of the fixed plate 614 in a stepped manner, facilitating the operator to maintain the filter plate 624 clamped inside the sliding frame 618. After the maintenance of the filter plate 624 is completed, the sliding frame 618 is pushed in the direction of the pull plate 612, and then the pull plate 612 is pushed into the housing 1. Through the fan mechanism 5, the air outside the housing 1 is inhaled into the housing 1 through the air inlet plate 637 and filtered by the maintained filter plate 624. When the filter plate 624 has been used for a long time and needs to be replaced, the filter plate 624 is pushed upward, so that the inner wall of the card slot 625 formed on the outer wall of the filter plate 624 contacts and presses against the inclined surface of the card block 623, so that the card block 623 drives the second magnetic plate 622 to slide into the frame slot 620 to remove the filter plate 624. The package of the new filter plate 645 is opened, and the new filter plate 645 is pushed from the bottom of the sliding frame 618 to the inner side of the sliding frame 618. The outer wall of the new filter plate 645 contacts and presses against the inclined surface of the card block 623. When the card slot 625 formed on the outer wall of the new filter plate 645 is aligned with the card block 623, under the action of the magnetic repulsion between the first magnetic plate 621 and the second magnetic plate 622, the card block 623 is clamped with the card slot 625 to achieve the effect of quickly installing the filter plate 624, facilitating the operator to replace and maintain the filter plate 624. Embodiment

[0040] A preferred embodiment of the easy-to-maintain air filter provided by the present invention is as follows Figures 1 to 9As shown: The closing assembly 63 includes a strip groove 631 formed in the inner wall of the housing 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 housing 1. A stop post 636 is fixedly installed on the outer wall of the air inlet plate 637. An arc groove 635 is formed in the inner wall of the housing 1.

[0041] In this embodiment, when the air filter needs to be maintained, pull the handle 619 so that the outer wall of the fixing plate 614 fixedly installed on the side wall of the pull plate 612 contacts and pushes the air inlet plate 637, causing the air inlet plate 637 to deflect with the hinge point on the inner wall of the housing 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, causing the extrusion strip 634 to slide into the strip groove 631 and compress the second spring 632 through the strip plate 633, so that the air inlet plate 637 opens to a vertical state. At this time, the filter plate 624 arranged on the outer wall of the pull plate 612 can be pulled out of the housing 1, and the operator can perform maintenance work on the filter plate 624. After the maintenance is completed, push the pull plate 612 into the housing 1. The air inlet plate 637 closes. Under the restriction of the arc groove 635, the stop post 636 fixedly installed at its end makes the two air inlet plates 637 in a horizontal state. The gap formed on the outer wall of the air inlet plate 637 allows external air to enter the housing 1 for filtering work. When the air inlet plate 637 is 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 clamped with the top surface of the air inlet plate 637 to limit the air inlet plate 637, avoiding the air inlet plate 637 from opening during the use of the air filter and affecting safety. This structure does not require the operator to use tools to open the air inlet plate 637 to maintain the air filter, improving the convenience of maintenance. Embodiment

[0042] A preferred embodiment of the easy-to-maintain air filter provided by the present invention is as Figures 1 to 9 As shown: The replacement assembly 64 includes a placement plate 641 fixedly installed on the side wall of the pull plate 612. A fixing block 642 is fixedly installed on the top surface of the placement plate 641. An opposed threaded rod 643 is sleeved inside the fixing block 642. A clamping plate 644 is sleeved on the outer wall of the opposed threaded rod 643. A new filter plate 645 is arranged on the top surface of the placement plate 641. A limiting rod 646 is slidably arranged at one end of the clamping plate 644 away from the opposed threaded rod 643.

[0043] In this embodiment, when the filter plate 624 has been used for a long time and needs to be replaced, pull the handle 619 to lift the pull plate 612 out of the housing 1, and rotate the opposed threaded rod 643. Since the end of the clamping plate 644 away from the opposed threaded rod 643 is slidably arranged on the outer wall of the limiting rod 646, under its restriction, the opposed threaded rod 643 can be driven to drive the clamping plate 644 to no longer clamp the new filter plate 645. At this time, unpack the package of the new filter plate 645 and replace the filter plate 624 with the new filter plate 645. This structure can store the brand-new new filter plate 645 inside the housing 1, facilitating the operator to quickly replace the filter plate 624 and avoiding the loss of the new filter plate 645 when it is stored independently, making the maintenance of the air filter more convenient.

[0044] Among them, the slider 617 fixedly installed on the outer wall of the sliding frame 618 is slidably arranged on the fixing plate 614 opened on the outer wall of the limiting groove 613, and the outer wall of the sliding frame 618 is slidably arranged on the outer wall of the fixing plate 614. Under its restriction, when the pull plate 612 is pulled out of the inside of the housing 1, the sliding frame 618 can be slid in the direction of the outside of the housing 1, driving the filter plate 624 clamped inside the sliding frame 618 to slide accordingly, facilitating the operator to maintain the filter plate 624.

[0045] Among them, one end of the first spring 616 is fixedly installed on the inner wall of the chute 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 sliding frame 618 is not restricted by the inner wall of the housing 1, it will drive the filter plate 624 clamped inside the sliding frame 618 to slide in the direction away from the pull plate 612, making the filter plate 624 in a stepped shape, facilitating the operator to maintain the filter plate 624.

[0046] Among them, the first magnetic plate 621 and the second magnetic plate 622 are magnetically repellent to each other, and the clamping block 623 is arranged in an inclined plane. Under the restriction, when the filter plate 624 is pushed into the inside of the sliding frame 618 from the bottom of the sliding frame 618, the outer wall of the filter plate 624 contacts and presses against the inclined plane of the clamping block 623, pushing the second magnetic plate 622 towards the first magnetic plate 621. When the clamping block 623 is clamped with the card slot 625, under the action of the magnetic repulsion between the first magnetic plate 621 and the second magnetic plate 622, the clamping block 623 is clamped with the card slot 625 to achieve the effect of quickly installing the filter plate 624, facilitating the operator to replace and maintain the filter plate 624.

[0047] Among them, the outer wall of the extrusion strip 634 is arranged in an arc surface, and the number of the extrusion strips 634 is two, symmetrically distributed with respect to the center line of the top surface of the housing 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 no longer clamps the top surface of the air inlet plate 637.

[0048] 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 restriction of the second spring 632, when the air inlet plate 637 is in a horizontal state, the second spring 632 will push the extrusion strip 634 in the direction away from the strip groove 631, so that the extrusion strip 634 is slidably clamped with the outer wall of the air inlet plate 637, avoiding the air inlet plate 637 from opening during use.

[0049] Among them, the outer wall of the opposed threaded rod 643 is threadedly sleeved inside the clamping plate 644, and one end of the clamping plate 644 away from the opposed threaded rod 643 is slidably arranged on the outer wall of the limiting rod 646. Under the restriction of the limiting rod 646, when the opposed threaded rod 643 rotates, the four clamping plates 644 can be driven to be divided into two groups to move towards or away from each other.
