Detailed Implementation

[0022] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the invention.

[0023] Reference Figures 1 to 4 The diagram illustrates a preferred embodiment of an air purifying fan, which includes a base 100, a fan housing 200, an impeller 300, a motor 400, and an air purification assembly 600. The base 100 is connected to the fan housing 200 via a fastener 500, and the base 100 is used to mount the air purifying fan to a fixed object such as a roof. The fan housing 200 has an air chamber 210, and the fan housing 210 has an air inlet 211 and an air outlet 212, both communicating with the air chamber 210, which are arranged opposite to each other. The base 100 is located on the side of the fan housing 200 where the air inlet 211 is located. The motor 400 is mounted on the base 100, and the impeller 300 is placed in the air chamber 210. The motor 400 is connected to the impeller 300 via a rotating shaft 800 to drive the impeller 300 to rotate, drawing air into the air chamber 210 from the air inlet 211 and out through the air outlet 212. The purification assembly 600 includes a purification housing 610, an ion generator 620, and an ion purification component 630. The purification housing 610 is located on one side near the air inlet 211 of the fan housing 200. The purification housing 610 has a purification chamber 613, and the ion purification component 630 is disposed in the purification chamber 613. The ion generator 620 is electrically connected to the ion purification component 630. The purification housing 610 has an air collecting port 611 and an air guiding port 612 communicating with the purification chamber 613. The air guiding port 612 is connected to the air inlet 211. Air enters the purification chamber 613 from the air collecting port 611, the ion purification component 630 purifies the air, and the purified air flows from the air guiding port 612 into the air inlet 211 of the fan housing 200, and finally flows out from the air outlet 212.

[0024] The air purifying fan of this invention combines purification and fan functions. When using the fan in summer, it can not only perform the fan function, but also purify indoor air, reduce dust and microorganisms in the air, reduce the risk of virus transmission, and save energy.

[0025] The ion purification component 630 includes an electric field electrode 631 and a dust collection electrode 632, which are arranged at intervals to form an electric field space 633 for air to pass through. The ion generator 620 is electrically connected to both the electric field electrode 631 and the dust collection electrode 632, wherein the electric field electrode 631 is the positive electrode and the dust collection electrode 632 is the negative electrode, or vice versa. In this embodiment, the electric field electrode 631 is the positive electrode and the dust collection electrode 632 is the negative electrode. An electric field is applied to the electric field space 633 between the electric field electrode 631 and the dust collection electrode 632. When air passes through the electric field space 633, dust in the air is adsorbed by the dust collection electrode 632, thus purifying the air. The purified air then enters the air inlet 211 of the fan casing 200 from the air guide 612.

[0026] As a preferred embodiment, there are multiple air collection ports 611, each equipped with an ion purification element 630. Each dust collection electrode 632 is a cylindrical structure with openings at both ends. The dust collection electrode 632 is connected to the air collection port 611, and the electric field electrode 631 extends into the cavity of the cylindrical dust collection electrode 632. The cylindrical structure of the dust collection electrode 632 creates a relatively long dust collection space, allowing for better adsorption of dust in the air. Preferably, the purification shell 610 includes a lower dust shell 602 and an upper dust shell 601. The air collection port 611 is located in the upper dust shell 601, and the air guide port 612 is located in the lower dust shell 602. The upper dust shell 601 and the lower dust shell 602 are joined to form a purification chamber 613. One end of the dust collection electrode 632 is connected to the upper dust shell 601, and the other end of the dust collection electrode 632 is into which the electric field electrode 631 extends.

[0027] There are multiple purification shells 610, which are arranged circumferentially along the base 100. The special purification shells 610 have a fan-shaped structure. The purification shells 610 and the fan shells 200 are detachably connected, which makes it easy to remove the purification shells 610 for cleaning.

[0028] The ion generator 620 is mounted on the base 100 and is electrically connected to the ion purification component 630 via wires.

[0029] The air purifying fan also includes a lighting component 900, which is mounted on the fan housing. This invention integrates fan, lighting, and purification functions into a single unit installed on the ceiling of the room, offering the advantage of space saving.

[0030] As shown in the figure, the lighting assembly 900 includes a circuit board 910 mounted on the outer wall of the lamp housing 200, a light source 920 disposed on the circuit board 910, a light source driver 930 electrically connected to the circuit board 910 and driving the light source 920 to emit light, and a lampshade 940 covering the circuit board 910 and distributing the light emitted from the light source 920. The light source driver 930 is mounted on the base 100 and electrically connected to the circuit board 910 via wires.

[0031] Furthermore, the air outlet 212 is equipped with a fence 700 to prevent small animals from entering the fan through the air outlet 212.

[0032] It should be noted that the embodiments of the present invention have better implementability and are not intended to limit the present invention in any way. Any person skilled in the art may use the above-disclosed technical content to change or modify it into equivalent effective embodiments. However, any modifications or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
