Abstract

An air purification device is suitable for a power supply and includes a casing mechanism, an ultraviolet light unit, and a safety protection unit. The housing mechanism includes a base housing with an air cleaning chamber formed with a maintenance hole, and a shield cover for closing the maintenance hole. Ultraviolet light emits ultraviolet light in an air-cleaning chamber. The safety protection unit includes a protective cover pressed against the shielding cover, a conduction control member electrically connected to the ultraviolet light unit when being pressed, and a pressing member detachably connected with the protective cover. When the pressing member is in the conduction position, it touches the conduction control member, and when it is in the disengagement position, it is separated from the conduction control member without ultraviolet light, and the protective cover can be detached. With the design of the safety protection unit, the pressing member and the protective cover need to be detached first, so as to ensure that the harmful ultraviolet light does not emit light before the shielding cover is detached.

Finally, the housing mechanism 2 is pressed down toward the hanging mechanism 1 along an arrow A, so that each first sub-connector 13 clamps against the corresponding second sub-connector 24, and the air purification is completed. installation of the device. If there is a need for movement, just pull out the second secondary connectors 24 from the first secondary connectors 13, and then move the housing mechanism 2 up slightly until the second main connectors 23 The head 232 can pass through the first through holes 121 of the first main connectors 12, and can be easily detached.

Referring to Fig. 4, Fig. 5 and Fig. 7, when using the air purification device, the pressing member 63 is located at the conduction position (as shown in Fig. 7), so that the ultraviolet light units 3 can receive electric energy and emit ultraviolet light, and the The air in the air cleaning room 33 is disinfected and sterilized. Then, utilize the flow guiding unit 4 to first guide the purified air in the air cleaning chambers 33 to the converging chamber 34, and then flow to the outside through the exhaust communication port 324 and the air outlets 254 in sequence. . At the same time, the unpurified air will enter the air purification chambers 33 through the air inlets 253 and the air inlet communication port 323 in order to complete the air purification cycle of the air purification device.

Referring to FIG. 3 and FIG. 8 , when the ultraviolet light units 3 need to be repaired or replaced, first use a tool (not shown) to take out the pressing member 63 by screwing. At this time, the pressing member 63 is switched to the separation position (as shown in FIG. 8 ), and the ultraviolet light units 3 are powered off and do not emit light. After that, detach the protective cover 61 in sequence, and disassemble the shielding cover 22 below the protective cover 61, so that the maintenance holes 331 can be opened to the outside, and then the air cleaning chamber located in the air cleaning room can be repaired or replaced. 33 of the UV unit 3.

Since the pressing member 63 needs to be removed first, the ultraviolet light units 3 cannot be powered and cannot generate ultraviolet light, and because the protective cover 61 also needs to be removed first, the shielding cover 22 can be detached again, Furthermore, it can avoid the situation that the ultraviolet light units 3 are still emitting light, but the maintenance hole 331 is mistakenly opened, so as to ensure that the harmful ultraviolet light will not irradiate the user.

2 to 4, it should be noted that the air cleaning chamber 33, the maintenance hole 331, the air inlet 253, the air outlet 254, the air inlet communication port 323, and the The shielding cover 22, the ultraviolet light unit 3, the covering part 612 of the protective cover 61, the first hook member 51, the second hook member 52, the third hook member 53, The numbers of the fourth hook member 54, the first main connector 12, the second main connector 23, the first secondary connector 13, and the second secondary connector 24 are not limited to two. According to actual needs, it can be one, three...etc.

To sum up, the air purification device of the present invention utilizes the anti-fooling power-off design of the safety protection unit 6. The pressing member 63 and the protective cover 61 need to be detached before the shielding covers 22 can be detached smoothly, thereby ensuring Before the shielding covers 22 are detached, the ultraviolet light units 3 are powered off and do not emit light, so as to protect the human body from being directly irradiated by ultraviolet light and causing harm. On the other hand, utilizing the design of the hanging mechanism 1 and the housing mechanism 2, the air cleaning device can be removed from the hanging mechanism 1 by hand and moved freely without tools, and more importantly, The air purification device can be hung on a high wall or ceiling, so that more floor space can be used flexibly, and the visual experience is simple and refreshing, and it avoids safety concerns caused by children putting their hands into the air purification device , and prevent people from tripping over the air purification device when walking around, creating a safe and secure indoor environment with good air quality. Furthermore, the design of the predetermined distance D between the hook unit 5 and the partition plate 32 makes it difficult for the user to touch the hook unit 5 from the outer surface of the device with tools or bare hands, and thus cannot easily open the housing mechanism. 2. To avoid the problem that the internal components and internal structure are exposed and easily damaged after the device is disassembled, so the purpose of the present invention can indeed be achieved.

But what is described above is only an embodiment of the present invention, and should not limit the scope of the present invention.
