Description

Filter Assemblies and Air Purifiers

technical field

The utility model relates to the field of air purification, and more specifically relates to a filter assembly with a package indicator module. The utility model also relates to an air purifier comprising the above filter assembly.

Background technique

It is known that an air cleaner is often provided with a filter assembly, and for the purposes of maintenance and cost reduction, the filter assembly is usually detachable. Filter assemblies typically include HEPA filters, activated carbon filters, electrostatic filters, and the like. The filter assembly is generally installed in the air duct in the air cleaner to filter the air taken in during the intake and discharge of ambient air by the air filter, and to make the air that has passed through the filter assembly relatively good in quality.

The existing filter assembly is often provided with a packaging film or packaging body for wrapping and protecting the filter material. In use, these wrapping films or wrappers need to be removed first to allow ambient air to pass through the filter assembly. However, in some cases, the user may install the filter assembly into the air purifier for operation without disassembling the packaging film or the packaging body. In this case, the air filter is ineffective in purifying the air, resulting in undesired waste and idling.

Accordingly, it would be desirable to provide a filter assembly and associated air cleaner that is capable of detecting whether the packaging on the filter assembly has been removed and prevents the air cleaner from idling.

However, existing air cleaners 100 suffer from significant disadvantages. Since the filter assembly 110 is detachable and replaceable, the user may forget to remove the packaging body when replacing the filter assembly 110 . At this point, ambient air cannot flow to the filter material, resulting in idling and waste of the air filter 100 .

Fig. 2 is a schematic view of the first state of an embodiment of the air purifier of the present invention. Wherein, at least a part of the body 110a of the filter assembly 110 is covered by the package 114, and the filter component 110 also includes a package indicator module. In the illustrated embodiment, the package indicating module includes a magnet 111 disposed on the package 114, and the magnet 111 is configured to cover the entire bottom of the body 110a. One or more magnetic sensors may be provided at positions corresponding to the magnets 111 in the housing 101 or the air duct 102 . In the illustrated embodiment, three Hall sensors 160 are provided. In addition, a display device 141 for displaying abnormal signals may be provided on the panel 140 . Hall sensor 160 and display device 141 are typically coupled to controller 150 .

When the user forgets to remove the package body 114, the hall sensor 160 senses the presence of the magnetic field emitted by the magnet 111, and emits a first signal. The controller 150 is configured to determine that the packaging body 114 has not been removed when receiving the first signal, send a warning signal through the display device 141 and set the air cleaner 100 to the standby mode, so as to prevent the user's misoperation from causing the air cleaner to 100's of idling.

FIG. 3 is a schematic diagram of a second state of the embodiment shown in FIG. 2 , wherein the packaging body 114 on the filter assembly 110 has been removed. At this time, the magnet 111 is also removed together with the packaging body 114 .

When the user has removed the packaging body 114 and the magnet 111, the Hall sensor 160 will not be able to sense the existence of the magnetic field, and will send out a second signal. The controller 150 is configured to judge that the body 114 has been removed when receiving the second signal, cancel the warning signal of the display device 141 and set the air purifier 100 to an available mode. At this point, the user can activate the air purifier 100 to filter the ambient air.

Optionally, the magnet 111 may be other magnetic components.

Alternatively, the magnet 111 may be bonded to the outer or inner surface of the package 114 .

Optionally, the magnet 111 may only cover a part of the packaging body 114 , such as a part corresponding to the three Hall sensors 160 shown in FIG. 2 .

Optionally, the packaging body 114 and the magnet 111 can also be installed on other parts of the body 110 a of the filter assembly 110 , such as the side, the top, and the like. At this time, the position of the Hall sensor 160 can also be changed accordingly.

Optionally, in addition to using the Hall sensor, those skilled in the art may also use other types of magnetic sensors according to actual needs.

Fig. 4 is a schematic view of the first state of another embodiment of the air purifier of the present invention. At least a portion of the body 110a of the filter assembly 110 is covered by the packaging body 114 . The filter assembly 110 also includes a package indication module. The package indicating module includes one or more metal sheets 112 arranged on the package 114 and one or more RFID tags 113 arranged on the body 110 a of the filter assembly 110 . Wherein, one or more metal sheets 112 are configured to cover one or more RFID tags 113 . Likewise, the metal sheet 112 may occupy part or all of the bottom of the body 110a. In addition, one or more RFID identification circuits 170 may be provided at positions corresponding to one or more RFID tags 113 on the housing 101 or the air duct 102 .

When the user forgets to remove the packaging body 114 , the metal sheet 112 will block the radio frequency signal sent by the RFID tag 113 . At this time, the RFID identification circuit 170 cannot sense the RFID tag 113, and will send out a third signal. The controller 150 is configured to determine that the packaging body 114 has not been removed when receiving the third signal, send a warning signal through the display device 141 and set the air cleaner 100 to the standby mode, so as to prevent the user's misoperation from causing the air cleaner to 100's of invalid running and idling.

FIG. 5 is a schematic diagram of a second state of the embodiment shown in FIG. 4 , wherein the packaging body 114 on the filter assembly 110 has been removed. At this time, the metal sheet 112 is also removed together with the packaging body 114 .

After the user has removed the packaging body 114 and the metal sheet 112, the RFID identification circuit 170 will sense the radio frequency signal sent by the RFID tag 113 and send out a fourth signal. The controller 150 is configured to judge that the packaging body 114 has been removed when receiving the fourth signal, then cancel the warning signal of the display device 141 , and set the air purifier 100 to an available mode. At this point, the user can activate the air purifier 100 to filter the ambient air.

Optionally, the RFID identification circuit 170 can be an RFID reader, etc., and the display device can be an LED or other suitable display device, such as an LED display screen.

Optionally, a metal sheet 112 can be used to cover the entire bottom of the body 110a.

Optionally, the metal sheet 112 may be adhered to the inner or outer surface of the package 114 .

Alternatively, metal sheet 112 may be composed of iron or other suitable metal.

Optionally, the metal sheet 112, the RFID tag 113 and the packaging body 114 can also be installed on other parts of the body 110a of the filter assembly 110, such as the side, top and so on. At this time, the position of the RFID identification circuit 170 can also be changed accordingly.
