Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, specifically to a filter component for air purification equipment that is easy to disassemble and replace. Background Technology

[0002] Air purification refers to providing comprehensive solutions for various indoor environmental problems, including sterilization and disinfection, dust reduction and haze removal, removal of harmful renovation residues and odors, improving living and working conditions, and enhancing physical and mental health. Indoor environmental pollutants and sources mainly include radioactive gases, mold, particulate matter, renovation residues, and secondhand smoke. Therefore, in daily life, it is often necessary to use purification equipment to treat the air in the environment. Air purification equipment, also known as air cleaners or purifiers, uses physical or chemical technologies to adsorb, decompose, or transform pollutants in the air, such as PM2.5, dust, formaldehyde, and bacteria, to improve air cleanliness. Its applications cover residential, commercial, industrial, and building environments.

[0003] A Chinese patent website (patent publication number CN222651610U) discloses an easily replaceable air purifier filter element, including a purifier body. The purifier body has a filter plate inside, a first slide rail and a second slide rail inside, a first slider and a second slider fixedly connected to the surface of the filter plate, a limiting block fixedly connected to the side of the filter plate, a limiting groove opened on the side of the purifier body, a placement groove opened at the bottom of the limiting groove, a slot opened between the top of the placement groove and the limiting groove, a spring fixedly connected to the bottom of the placement groove, a limiting plate fixedly connected to the top of the spring, and a pull rod fixedly connected to the side of the limiting plate.

[0004] The aforementioned air purification equipment uses a limiting plate and elastic fastener to quickly fix the filter plate to the main body of the purifier, thus ensuring stable installation. However, in actual operation, the limiting plate still needs to be operated before the filter plate can be removed individually. The installation and disassembly process still involves many steps, which is inconvenient for maintenance and cleaning after filtration. Therefore, we propose a filter component for air purification equipment that is easy to replace. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this invention is to provide a filter assembly for air purification equipment that is easy to replace, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filter assembly for an air purification device that is easy to disassemble and replace, comprising a main frame, a filter mechanism disposed at the center of the main frame, the filter mechanism comprising a filter frame, a handle fixed to one end of the filter frame, a filter plate attached to the middle of the inner wall of the filter frame, a material platform engaged at the bottom end of the filter plate, fasteners fixed to both sides of the bottom end of the material platform, a guide rod passing through one end of the material platform, a spring frame sleeved at the bottom end of the guide rod, axial locking rods distributed inside the bottom end of the filter frame, a central shaft post disposed at the center of the axial locking rod, a latch disposed at one end of the axial locking rod, a linkage post disposed at the other end of the axial locking rod, a return spring connected to the back of the linkage post, dust filter screens attached to both outer walls of the filter plate, a sliding groove provided on both outer walls of the bottom end of the filter frame, a sliding base attached to the outer wall of the sliding groove, slide rails provided on both inner walls of the sliding base, and a reserved groove provided at one end of the slide rail.

[0008] Furthermore, the filter frame is slidably engaged with the sliding base via sliding grooves on both sides, and the dust filter screen is fixedly connected along both sides of the filter frame.

[0009] Furthermore, the material platform is connected to the inner wall of the filter frame via a guide rod and spring frame at one end to form an elastic lifting structure, and the material platform is fixed by fasteners and locks on both sides of the bottom end.

[0010] Furthermore, the latch and linkage stake are fixedly connected to both ends of the axial locking rod, and the axial locking rod is symmetrically distributed along both sides of the bottom end of the filter frame.

[0011] Furthermore, the axial locking rod forms an elastic structure with the central shaft and the return spring, and the linkage post at one end of the axial locking rod is exposed in the slide groove.

[0012] Furthermore, the main frame includes an outer shell, a sliding base is fixed to one side of the outer wall of the outer shell, an air inlet is fixedly connected to one end of the outer shell, an air outlet is fixedly connected to the other end of the outer shell, and a bracket is fixed to the bottom of the air inlet and the air outlet.

[0013] Furthermore, the air outlet and air inlet are connected to the interior of the outer casing, and the brackets are symmetrically distributed along the bottom of both ends of the outer casing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] During cleaning and maintenance, as the filter frame slides out, the linkage pin disengages from the slide rail and enters the pre-reserved slot area. Therefore, the two sets of axial locking rods built into the bottom of the filter frame can be elastically reset by the return spring. This, combined with the sliding process, causes the axial locking rods to rotate elastically, unlocking the locking pin at the other end of the axial locking rod. This allows the material platform to slide upwards under the spring force of the frame. During the sliding process, the filter plate locked at the top of the material platform pops out simultaneously, making it easier for users to remove the filter plate for cleaning or replacement. The removal of the component and the automatic pop-out of the filter section can be completed with a simple pull operation, further facilitating the cleaning and maintenance of the equipment.

[0016] This filter assembly consists of a sliding base fixed to the outer shell and a filter frame that slides together. The entire filter frame can be slid out from one side of the outer shell by holding the handle, so as to clean the dust filter screens fixed on both sides of the filter frame. The operation is convenient and quick.

[0017] This air purifier consists of an outer casing and an air inlet and outlet connected at both ends. It exhausts air through fans in the two sets of air outlets. During the exhaust process, it is kept stable by a support structure, while the internal part is closely connected to the filter mechanism, which can maximize the filtration and purification during the exhaust process.

[0028] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] This utility model provides, for example Figure 1-5 The filter assembly for an air purification device that is easy to replace includes a main frame 1. A filter mechanism 2 is disposed in the center of the main frame 1. The main frame 1 includes an outer shell 101. A sliding base 215 is fixed to one side of the outer wall of the outer shell 101. An air inlet 102 is fixedly connected to one end of the outer shell 101, and an air outlet 103 is fixedly connected to the other end of the outer shell 101. A bracket 104 is fixed to the bottom of the air inlet 102 and the air outlet 103.

[0030] To ensure the stable operation of the overall air purification equipment and to fully utilize the filtration process, such as Figure 1-2 As shown, this air purification device consists of an outer casing 101 and an air inlet 102 and an air outlet 103 connected at both ends. It can exhaust air through the fans in the two sets of air outlets. During the exhaust process, it is kept stable by the support structure 104. The internal part is closely connected to the filter mechanism 2, which can maximize the filtration and purification during the exhaust process.

[0031] like Figure 3-5As shown, the filter mechanism 2 includes a filter frame 201, with a handle 202 fixed to one end. A filter plate 203 is attached to the middle of the inner wall of the filter frame 201. A material platform 204 is engaged at the bottom end of the filter plate 203. Fasteners 205 are fixed to both sides of the bottom end of the material platform 204. A guide rod 206 passes through one end of the material platform 204. A spring frame 207 is sleeved at the bottom end of the guide rod 206. Shaft-moving locking rods 208 are distributed inside the bottom end of the filter frame 201. A central locking rod is set at the center of the shaft-moving locking rod 208. A shaft pile 209 is provided with a latch 210 at one end of a shaft-moving locking rod 208, and a linkage pile 211 is provided at the other end of the shaft-moving locking rod 208. A return spring 212 is connected to the back of the linkage pile 211. Dust filter screens 213 are attached to the outer walls of both sides of the filter plate 203. A sliding groove 214 is provided on the outer walls of both sides of the bottom end of the filter frame 201. A sliding base 215 is attached to the outer wall of the sliding groove 214. A slide rail 216 is provided on the inner walls of both sides of the sliding base 215. A reserved groove 217 is provided at one end of the slide rail 216.

[0032] To facilitate cleaning and maintenance of the entire filter assembly, such as Figure 3-5 As shown, this filter assembly consists of a sliding base 215 fixed to the outer shell 101 and a filter frame 201 that slides together. The entire filter frame 201 can be slid out from one side of the outer shell 101 by holding the handle 202, thereby cleaning the dust filter screen 213 fixed on both sides of the filter frame 201. The operation process is convenient and quick.

[0033] During the cleaning and maintenance of the aforementioned filter assembly, as the filter frame 201 slides out, the linkage post 211 can slide out of the slide rail 216 and enter the reserved slot 217 area. Therefore, the two sets of axial locking rods 208 built into the bottom of the filter frame 201 can be elastically reset by the return spring 212. This, in conjunction with the sliding process, allows the axial locking rods 208 to elastically rotate, completing the unlocking of the other end of the axial locking rod 208, the latch 210, onto the latch post 205. This allows the material table 204 to slide upwards under the elastic pressure of the spring frame 207. During the sliding and pulling process, the filter plate 203, which is engaged at the top of the material table 204, pops out simultaneously, making it easier for the user to remove the filter plate 203 for cleaning or replacement. The removal of the assembly and the automatic pop-out of the filter part can be completed with just a pull operation, further facilitating the cleaning and maintenance of the equipment.

[0034] In summary, when using this filter assembly, the user can first hold the handle 202 and slide the filter frame 201 along one side of the outer shell 101 to pull it out. During the sliding process, the linkage pins 211 in the sliding grooves 214 on both sides of the bottom of the filter frame 201 slide into the reserved groove 217 area, and are no longer limited by the slide rails 216 on both sides of the inner wall of the sliding base 215. At this time, one end of the linkage pin 211 of the axial locking rod 208 is reset by the elastic force of the return spring 212. At the same time, the axial locking rod 208 itself rotates with the central shaft pin 209 of the elastic center. During the rotation process, the latch 210 at the other end of the axial locking rod 208 unlocks the latch pins 205 on both sides of the bottom of the material table 204. Once the material platform 204 loses its locking position, the spring frame 207 at one end of the material platform 204 elastically resets, causing the material platform 204 to rise along the guide rod 206. At this time, the filter plate 203 on the top surface of the material platform 204 extends out simultaneously, exceeding the height of the dust filter screens 213 on both sides. The user can directly remove it, clean or replace it, and then re-insert the dust filter screen 213 into the material platform 204 and press it down, so that its locking post 205 and locking lock 210 are in contact. At the same time, the filter frame 201 is slid into the equipment. Relying on the pressure of the linkage post 211 of the shaft locking rod 208, the shaft locking rod 208 rotates by its own angle, which can complete the re-locking of the locking post 205 and locking lock 210.

[0035] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
