Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, and in particular to an air purifier. Background Technology

[0002] In modern life, air purifiers have become an important device for improving indoor air quality. Their core component, the filter cartridge, accumulates a large amount of dust, particulate matter, and other pollutants after prolonged use, requiring regular disassembly, cleaning, or replacement.

[0003] However, when users remove the filter cartridge from the air purifier during the disassembly process, the dust adhering to the surface of the filter cartridge can easily spread everywhere, polluting the indoor environment and affecting health.

[0004] To prevent dust from spreading indoors, air purifiers need to be moved to a suitable outdoor location for operation. However, air purifiers are large and heavy, and frequently moving them outdoors is not only extremely inconvenient to operate, but may also cause damage to the equipment due to bumps and knocks during transport. Utility Model Content

[0005] The purpose of this invention is to provide an air purifier that solves the problem that when the filter cartridge of an air purifier is disassembled, the dust attached to the surface of the filter cartridge is easily scattered everywhere, polluting the indoor environment and affecting health.

[0006] To achieve the above objectives, this utility model provides an air purifier, including a housing, a fan, and a filter cartridge. The filter cartridge is disposed inside the housing, and the fan is connected to the housing and located at the top of the filter cartridge. The device also includes a mounting assembly. The mounting assembly includes a mounting base, a protective cover, a magnetic plate, a top plate, and a locking component. The mounting base is connected to the housing and the filter cartridge, and is disposed on the housing. The magnetic plate is magnetically connected to the housing and is disposed on the housing. The two ends of the protective cover are respectively connected to the mounting base and the magnetic plate. The top plate is fixedly connected to the filter cartridge and is located on the side of the filter cartridge closer to the fan. The locking component is disposed on the mounting base.

[0007] The locking component includes a locking seat and a driving seat. The locking seat is slidably connected to the mounting base and is located inside the mounting base. The driving seat is slidably connected to the mounting base and to the locking seat, and is disposed on the mounting base.

[0008] The locking seat has a drive groove, which is disposed on the locking seat and extends through the locking seat.

[0009] The drive seat includes a seat body, a drive shaft, a pull rod, and a compression spring. The seat body is slidably connected to the mounting seat and is located inside the mounting seat. The drive shaft is fixedly connected to the seat body and extends into the drive groove. The pull rod is fixedly connected to the seat body and is located on one side of the seat body. The two ends of the compression spring are respectively connected to the seat body and the mounting seat, and the compression spring is sleeved on the pull rod.

[0010] The mounting base has a limiting protrusion, which is disposed on one side of the mounting base; the housing has a limiting groove, which is disposed on the side of the housing near the limiting protrusion, and the limiting groove cooperates with the limiting protrusion.

[0011] This utility model discloses an air purifier. When the filter cartridge needs to be disassembled, the outer shell is placed horizontally, and the locking component is released from the mounting base. At this time, the mounting base and the filter cartridge are pulled out. As the mounting base moves outward, the protective cover folded and stored in the storage slot is gradually stretched and unfolded. One end of the protective cover moves with the mounting base, while the magnetic suction plate at the other end remains fixed due to its magnetic connection with the outer shell. When the top plate moves to the magnetic suction plate, the top plate drives the magnetic suction plate to move and detach from the outer shell. Since the magnetic suction plate can also be magnetically connected to the top plate, after separation, the magnetic suction plate will adhere to the top plate, allowing the protective cover to fully unfold and cover the outside of the filter cartridge, preventing dust from the surface of the filter cartridge from escaping. At this time, the user can move the mounting base and the filter cartridge to a well-ventilated place such as a balcony or outdoors to clean the filter cartridge, avoiding the problem of dust adhering to the filter cartridge escaping into the room during the disassembly process, affecting the indoor environment and health.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1 to 5 ,in Figure 1 This is a schematic diagram of the overall structure of an air purifier. Figure 2 This is a structural diagram of the installed components. Figure 3 This is a schematic diagram of the limiting protrusion. Figure 4 This is a structural diagram of the locking component. Figure 5 This is a schematic diagram of the drive shaft mounting structure.

[0021] This utility model provides an air purifier, including a housing 101, a fan 102, a filter cartridge 103, and a mounting assembly 104. The mounting assembly 104 includes a mounting base 105, a protective cover 106, a magnetic plate 107, a top plate 108, and a locking component 109. The locking component 109 includes a locking seat 110 and a drive seat 111. The locking seat 110 has a drive groove 112, and the drive seat 111 includes a seat body 113, a drive shaft 114, a pull rod 115, and a compression spring 116. The mounting base 105 has a limiting protrusion 117, and the outer shell 101 has a limiting groove 118. When the mounting base 105 and the filter cartridge 103 are disassembled, the protective cover 106 can be unfolded and fitted onto the outside of the filter cartridge 103 to prevent dust adhering to the filter cartridge 103 from escaping into the room. It is understood that the aforementioned solution can be used to prevent dust adhering to the filter cartridge 103 from escaping into the room, and can also be used to lock the mounting base 105 onto the outer shell 101.

[0022] In this specific embodiment, the filter cartridge 103 is disposed inside the outer casing 101. The fan 102 is connected to the outer casing 101 and located at the top of the filter cartridge 103. The outer casing 101 has several air inlets on its periphery and an air outlet on the side of the outer casing 101 near the air outlet of the fan 102. The filter cartridge 103 is hollow and consists of, from the inside out, an activated carbon filter layer, a fiber mesh filter layer, and a primary filter layer. The air inlet of the fan 102 is correspondingly positioned at one end of the filter cartridge 103, and the two are connected by the top plate 1. 08 Sealing; When the fan 102 is started, indoor air enters through the air inlet on the outer casing 101 under negative pressure. It first passes through the primary filter layer to filter large particulate pollutants such as hair and lint. Then the air enters the fiber filter layer to further purify the air for fine dust such as PM2.5. Finally, the air passes through the activated carbon filter layer, which utilizes the rich pore structure of activated carbon to efficiently adsorb harmful gases such as formaldehyde and odors. The purified air is finally discharged through the air outlet and air hole of the fan 102. This part is existing technology and will not be described in detail here.

[0023] The mounting base 105 is connected to the outer shell 101 and the filter cartridge 103, and is disposed on the outer shell 101. The magnetic suction plate 107 is magnetically connected to the outer shell 101 and is disposed on the outer shell 101. The two ends of the protective cover 106 are respectively connected to the mounting base 105 and the magnetic suction plate 107. The top plate 108 is fixedly connected to the filter cartridge 103 and is located on the side of the filter cartridge 103 near the fan 102. The locking member 109 is disposed on the mounting base 105. The mounting base 105 is provided with a storage groove, and the protective cover 106 can be folded and stored in the storage groove. The magnetic suction plate 107 is magnetic and can be magnetically connected to the outer shell 101 and the top plate 108. The locking member 109 is used to lock the mounting base 105 onto the outer shell 101.

[0024] When the filter cartridge 103 needs to be disassembled, the outer shell 101 is placed horizontally, and the locking member 109 is released from the mounting base 105. At this time, the mounting base 105 and the filter cartridge 103 are pulled out. As the mounting base 105 moves outward, the protective cover 106, which is folded and stored in the storage groove, is gradually stretched out. One end of the protective cover 106 moves with the mounting base 105, while the magnetic suction plate 107 at the other end remains fixed due to its magnetic connection with the outer shell 101. When the top plate 108 moves to the magnetic suction plate 107, the top plate 108 drives the magnetic suction plate 107 to move. The filter cartridge 103 is detached from the outer casing 101. Since the magnetic plate 107 can still be magnetically connected to the top plate 108, after separation, the magnetic plate 107 will adhere to the top plate 108, allowing the protective cover 106 to fully unfold and cover the outside of the filter cartridge 103, preventing dust from the surface of the filter cartridge 103 from escaping. At this time, the user can move the mounting base 105 and the filter cartridge 103 to a well-ventilated place such as a balcony or outdoors to clean the filter cartridge 103, avoiding the problem of dust attached to the filter cartridge 103 escaping into the room during the disassembly process, which could affect the indoor environment and health.

[0025] Secondly, the locking seat 110 is slidably connected to the mounting seat 105 and is located inside the mounting seat 105; the driving seat 111 is slidably connected to the mounting seat 105 and to the locking seat 110, and is disposed on the mounting seat 105; there are two locking seats 110, and the outer shell 101 is provided with locking grooves that cooperate with the locking seats 110. The driving seat 111 is used to drive the two locking seats 110 to move, so that the locking seats 110 can extend into or move out of the locking grooves, thereby locking or unlocking the mounting seat 105.

[0026] Meanwhile, the drive groove 112 is disposed on the locking seat 110 and extends through the locking seat 110.

[0027] In addition, the seat 113 is slidably connected to the mounting base 105 and is located inside the mounting base 105; the drive shaft 114 is fixedly connected to the seat 113 and extends into the drive groove 112; the pull rod 115 is fixedly connected to the seat 113 and is located on one side of the seat 113; the two ends of the compression spring 116 are respectively connected to the seat 113 and the mounting base 105, and the compression spring 116 is sleeved on the pull rod 115.

[0028] The drive groove 112 is inclined, and there are two drive shafts 114, which extend into the two drive grooves 112 respectively. The end of the pull rod 115 is also equipped with a pull ring, which makes it convenient for the user to pull the pull rod 115 to move. When the mounting base 105 and the filter cartridge 103 are disassembled, pulling the pull ring will drive the pull rod 115 to move, which will drive the base 113 and the drive shaft 114 to move. Since the drive groove 112 is inclined, when the drive shaft 114 slides in the drive groove 112, it will drive the locking seat 110 to slide inside the mounting base 105, thereby moving the locking seat 110 out of the locking groove. At this time, the mounting base 105 is unlocked.

[0029] Finally, the limiting protrusion 117 is disposed on one side of the mounting base 105; the outer shell 101 has a limiting groove 118, which is disposed on the side of the outer shell 101 near the limiting protrusion 117, and the limiting groove 118 cooperates with the limiting protrusion 117; there are two of each of the limiting protrusion 117 and the limiting groove 118. When the mounting base 105 is installed on the outer shell 101, the limiting protrusion 117 extends into the limiting groove 118, thereby limiting the mounting base 105 and improving the stability of the mounting base 105.

[0030] When using the air purifier of this utility model, if it is necessary to disassemble the filter cartridge 103, release the locking member 109 from the mounting base 105. At this time, the mounting base 105 and the filter cartridge 103 can be pulled out from the outer shell 101 together. During the process of pulling out the mounting base 105, the protective cover 106, which was originally folded and stored in the storage slot, will gradually unfold as the mounting base 105 moves. One end of the protective cover 106 is connected to the mounting base 105, and the other end is connected to the magnetic suction plate 107. The magnetic suction plate 107 is fixed due to its magnetic connection with the outer shell 101. When the top plate 108 approaches the magnetic suction plate 107 as the mounting base 105 moves, the top plate... 108 will move the magnetic suction plate 107 together, causing the magnetic suction plate 107 to disengage from the outer shell 101. Since the magnetic suction plate 107 can still be magnetically connected to the top plate 108, after separation, the magnetic suction plate 107 will be attracted to the top plate 108, ensuring that the protective cover 106 can be fully unfolded and tightly fitted on the outside of the filter cartridge 103. At this time, the filter cartridge 103 is completely wrapped by the protective cover 106, effectively preventing the dust attached to the filter cartridge 103 from escaping into the indoor air during disassembly. Users can move the mounting base 105 and the filter cartridge 103 to a well-ventilated place such as a balcony or outdoors for cleaning or replacement without worrying about dust polluting the indoor environment or affecting health.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
