[0032] The filter 14 is a hollow and cylindrical filter body having a hollow space 141 for filtering the external air.

[0033] The filter cover 15 is an annular body disposed between the lower side of the filter 14 and the lower opening 112 of the lower housing 11.

[0034] The aromatizing device 16 is composed of an aromatizing piece 161 and a mounting seat 162, both of which are disposed within the hollow space 141 of the filter 14 for aromatizing the purified air from the filter 14 to generate purified and aromatized air.

[0035] The bottom cover 17 is used to seal the hollow portion 151 of the filter cover 15.

[0036] The air purifying unit 100 further includes a first extension connector 181 mounted on the top surface of the upper housing 12 and a second extension connector 182 mounted on the bottom surface of the lower housing 11. The first extension connector 181 and the second extension connector 182 are mated in a male-to-female configuration, such that the air purifying unit 100 can be used solely, or jointly by vertically cascading a multiplicity of the air purifying units 100.

[0037] In a preferred embodiment of the invention, the upper housing 12 includes a control circuit board 19 mounted therein and connected to the switch 123, the first extension connector 181, the second extension connector 182, and the fan 13. The control circuit board 19 is mounted on the bottom surface of the switch 123, and the fan 13 is mounted below the control circuit board 19 and is close to the air outlets 122.

[0038] In a preferred embodiment of the invention, the control circuit board 19 is controllable to select the aromatizing mode of the air purifier or the aromatizing effect of the air purifying unit 100 (for example, by adjusting the air discharge volume) through an application (app) 210 of a mobile device 200 by network transmission signals 220. The network transmission signals 220 may be Wi-Fi signals, Bluetooth signals, or Zigbee signals.

[0039] In a preferred embodiment of the invention, the filter 14 is made up of a filter material selected from the group consisting of a high efficiency particulate air (HEPA) filter, an ultra low penetration air (ULPA) filter, nano photocatalysts, an active carbon filter, and an electrostatic filter.

[0040] In a preferred embodiment of the invention, the top surface of the mounting seat 162 is provided with a round groove 163 for allowing the aromatizing piece 162 to be mounted therein. The bottom surface of the mounting seat 162 is provided with a multiplicity of legs 164 extending downwardly. The top surface of the bottom cover 17 is provided with a multiplicity of hollow cylinders 171 extending upwardly for receiving the legs 164 of the mounting seat 162 to secure the mounting seat 162.

[0041] In a preferred embodiment of the invention, a lucid ring body 125 is mounted between the upper housing 12 and the lower housing 11. Also, a light-emitting diode (LED) 126 is electrically connected to the control circuit board 19 and is disposed on the inside of the lucid ring body 125. The LED 126 is used as an indication of the power of the air purifying unit 100. When the switch 123 is depressed to turn on the air purifying unit 100, the LED 126 will illuminate such that light is emitted through the lucid ring body 125.

[0042] The operation of the air purifying unit 100 is described with reference to FIGS. 2 and 3, in which FIG. 2 is a cross-sectional view of the air purifier with the switch 123 not being depressed and FIG. 3 is a cross-sectional view of the air purifier with the switch 123 being depressed. As shown in FIG. 3, the switch 123 is depressed and thus the LED 126 illuminates, such that the light is emitted through the lucid ring body 125. In the meantime, the fan 23 starts to operate. The air enters the air purifying unit 100 through the air inlets 113, as indicated by the arrow-headed lines A1 and A2. The air is filtered by the filter 14 into purified air, which would pass through the aromatizing device 16 disposed in the hollow space 141 of the filter 14, such that the purified air is aromatized by the aromatizing piece 161 to generate purified and aromatized air. The fan 13 is used to blow the purified and aromatized air toward the upper housing 12, as indicated by the arrow-headed lines B1 and B2. Afterwards, the purified and aromatized air is discharged to the outside through the air outlets 122 of the air purifying unit 100, as indicated by the arrow-headed lines C1 and C2. In this way, the air purifying unit 100 can aromatize the air while purifying the air to generate purified and aromatized air, in order to disinfect, sterilize, and aromatize the indoor air of the place where the air purifying unit 100 is located. In brief, the invention can provide an air purifier with high portability and easy-to-operation characteristics. Thus, the invention possesses potentiality to contain the pandemic of virus.

[0043] Please refer to FIGS. 3 and 4, in which FIG. 4 is a schematic diagram showing the air purifier combined with an aromatizing device being controllable by a mobile device. As shown, the air purifying unit 100 can be used solely. As the air purifying unit 100 includes a filter 14 and an aromatizing device 16, a single purifying unit 100 is adequate for the purification and aromatization of the fir. Also, as the air purifying unit 100 includes a control circuit board 19, the user may use a mobile device 200 to execute an application (APP) 210 installed in the mobile device 200 to control the operation of the air purifying unit 100 through the selection of different aromatizing mode for the air purifier by network transmission signals 220.

[0044] Please refer to FIGS. 3-5, in which FIG. 5 is a schematic diagram showing the air purifier being implemented by cascading a multiplicity of air purifying units. As shown, the air purifying unit 100 further includes a first extension connector 181 mounted on the top surface of the upper housing 12, and a second extension connector 182 mounted on mounted on the bottom surface of the lower housing 11. Hence, the inventive air purifier can be implemented by a single air purifying unit 100 as shown in FIG. 3 or implemented by a multiplicity of air purifying units 100a-100d that are vertically cascaded as shown in FIG. 5. In FIG. 5, each of the air purifying unit 100a-100d includes a first extension connector 181 mounted on the top surface of the upper housing and a second extension connector 182 mounted on mounted on the bottom surface of the lower housing, such that all of the air purifying unit 100a-100d can be electrically interconnected when they are cascaded. The user may use the application 210 of the mobile device 200 to select a desired aromatizing mode by sending the related messages to the air purifying unit 100a-100d by network transmission signals 220.

[0045] In this embodiment, each aromatizing device 16 of the air purifiers 100a-100d may be implemented by a specific kind of aromatizing piece 161. For example, the aromatizing piece 161 may be a bergamot oil aromatizing piece, a geranium oil aromatizing piece, a cedarwood oil aromatizing piece, or a lavender oil aromatizing piece. Therefore, the user may select the aromatizing mode through the application 210 of the mobile device 200. For example, when one of the air purifying units is selected, the selected air purifying unit can generate purified air with a single aroma. When two or more air purifying units are selected, the selected air purifying units can generate purified air with a mixed aroma. In this embodiment, the number of the air purifying units is set to four. However, the number of the air purifying units may be set to any arbitrary number.

[0046] Although the structure and the operation of the inventive air purifier combined with aromatizing device have been described herein, it is to be noted that those of skill in the art will recognize that various modifications can be made within the spirit and scope of the present invention as further defined in the appended claims.
