The fan 200 is used to suck and discharge the gas to the purge air duct 12.

The air purification module 100 of the embodiment of the invention has a simple structure and better effects of removing peculiar smell and purifying air by arranging the activated carbon purification unit 80.

The activated carbon is a very fine carbon particle having a large surface area, and thus, the activated carbon can be sufficiently contacted with air. In addition, there are finer pores, capillaries, in the carbon granules. The capillary has strong adsorption capacity, and impurities in the air can be adsorbed when contacting the capillary, so that the air is purified. The activated carbon adsorption method has the advantages of wide application, mature process, safety, reliability and more types of absorbed substances, and the activated carbon purification unit 80 is arranged on the air purification module 100, so that the method is simple and convenient, and is beneficial to further evolution of air and removal of peculiar smell.

In some embodiments, the frame 22 includes two connecting plates 222 and a plurality of connecting posts 224, the two connecting plates 222 being disposed opposite and spaced apart. A plurality of connecting posts 224 connect the two connecting plates 222 and are spaced apart. The multi-turn coil 24 is wound on a plurality of connecting posts 224 and arranged at intervals along the axial direction of the connecting posts 224.

In one example, as shown in FIG. 6, there are four connection posts 224; in another example, there are six connecting posts 224; in yet another example, there are eight connecting posts 224. The number of connecting posts 224 is not limited herein.

In some embodiments, both connection plates 222 are insulators. In this way, the two connecting plates 222 can shield the electric field generated by the coil, and prevent the electric field from leaking to improve the safety of the ozone generating device 20. Specifically, the connection plate 222 may be made of an insulating material such as acryl. The two connection plates 222 may be symmetrically distributed about a central axis of the air purification module 100.

Referring to fig. 6, in some embodiments, each connection plate 222 has a rectangular cross section, the length a of the connection plate 222 is 145-150mm, and the width B is 150-160 mm.

It can be understood that, since the purifying housing 10 is in the shape of a square cylinder, the connecting plate 222 with a rectangular cross section can be adapted to the purifying housing 10, so that the air purifying module 100 is more compact, which is beneficial to the miniaturization of the air purifying module 100.

In addition, the length A of the connection plate 222 can be arbitrarily set within the range of 145-150mm, and the width B of the connection plate 222 can be arbitrarily set within the range of 150-160 mm.

In one example, the length A of the connection plate 222 is 145mm, and the width B is 150 mm; in another example, the web 222 has a length A of 150mm and a width B of 160 mm; in yet another example, the web 222 has a length A of 147mm and a width B of 155 mm.

In some embodiments, the plurality of connecting posts 224 enclose a rectangular parallelepiped space, and the plurality of turns of the coil 24 are uniformly spaced along the axial direction of the connecting posts 224. It can be understood that, since the purifying housing 10 is in a square cylinder shape and the cross section of the connecting plate 222 is in a rectangular shape, the connecting column 224 encloses a rectangular space which can be adapted to the purifying housing 10 and the connecting plate 222, so that the air purifying module 100 is more compact, which is beneficial to the miniaturization of the air purifying module 100. In addition, the multi-turn coils 24 are uniformly distributed at intervals along the axial direction of the connecting column 224, which is beneficial to the beauty and regularity of the product.

Referring to fig. 14, in some embodiments, an operating voltage is applied between any two adjacent turns of the coil 24, and a distance C between two adjacent turns of the coil is 10-15 mm. That is, the distance C between two adjacent turns of the coil may take any value between 10 and 15 mm.

In one example, the spacing C between two adjacent turns is 10 mm; in another example, the spacing C between two adjacent turns is 15 mm; in yet another example, the spacing C between two adjacent turns is 12.5 mm.

In one embodiment, the coils 24 to which a low potential is applied are alternately spaced from the coils 24 to which a high potential is applied in the arrangement direction of the multi-turn coils 24. Wherein the low potential is 0V, and the high potential is 3000-3500V. For example, in the direction in which the multi-turn coil 24 is arranged, the first turn coil 24 has a low potential (e.g., 0V), the second turn coil 24 has a high potential (e.g., 3000V), and the third turn coil 24 has a low potential … …, which are arranged in this order.

Referring to fig. 15, in another embodiment, the first turn coil 24 has a low potential (e.g., 0V), the second turn coil 24 has a low potential (e.g., 0V), the third turn coil 24 has a high potential (e.g., 3000V), the fourth turn coil 24 has a high potential (e.g., 3000V), the fifth turn coil 24 has a low potential (e.g., 0V), and the sixth turn coil 24 has a low potential (e.g., 0V) … ….

Note that the above phrases "first", "second", "third", and the like represent the relative positional relationship between the coils 24 to which the electric potentials are applied, not the sequence of the coils among all the coils 24. For example, in one example, the coil 24 has 18 turns, the first turn of the coil 24 has a low potential (e.g., 0V), the second turn of the coil 24 has a high potential (e.g., 3000V), and the third turn of the coil 24 has a low potential (e.g., 0V). The first turn of the coil 24 in this example is relative to the second and third turns of the coil 24, and may be the first turn of an 18 turn coil, the second turn of an 18 turn coil, or the third turn of an 18 turn coil. In addition, the terms "first", "second", "third", and the like do not denote that the coils 24 to which electric potential is applied are adjacent, and the coils 24 to which electric potential is not applied may be spaced therebetween. Further, as shown in fig. 16, the application of the electric potential to the multi-turn coil 24 may also be irregular.

In some embodiments, the number of turns of coil 24 is 15-20 turns. That is, the number of turns of the coil 24 may take any value between 15 and 20 turns. In one example, the number of turns of the coil 24 is 15; in another example, the coil 24 has 20 turns; in yet another example, the number of turns of the coil 24 is 17 turns.

In some embodiments, the operating voltage is 3000-. As mentioned above, the oxygen can form ozone under the condition of discharging, and the efficiency of generating ozone can be higher when the working voltage is 3000-3500V. In one example, the operating voltage is 3000V; in another example, the operating voltage is 3500V; in yet another example, the operating voltage is 3200V.
