Referring to fig. 1 to 5, a purification apparatus 100 according to an embodiment of the present disclosure includes a housing 10 and a purification assembly 20. The purification assembly 20 is disposed in the housing 10, the purification assembly 20 includes a cover plate 21 and a coil assembly 22 mounted on the cover plate 21, an accommodating space 30 is provided between the cover plate 21 and the housing 10, and the coil assembly 22 is located in the accommodating space 30 and is used for generating ozone.

Therefore, the ozone generated by the coil assembly 22 during operation is not easy to overflow due to the covering of the cover plate 21, so that the ozone quantity of output can be managed and controlled, and a large amount of ozone is prevented from overflowing to cause certain damage to a human body.

Preferably, the housing 10 may be made of plastic, which is easy to obtain and has high plasticity, thereby facilitating mass production of the purification apparatus 100. In one example, the housing 10 may be made of stainless steel to facilitate scrubbing of the housing 10. The specific material of the housing 10 is not limited herein. Specifically, the housing 10 may have a cylindrical shape or a rectangular parallelepiped shape, and the shape of the housing 10 is not limited herein.

The coil assembly 22 is capable of ionizing air to form ozone upon application of an operating voltage. Ozone is a strong oxidant, can destroy the cell wall of the decomposing bacteria, so as to diffuse into the cell and oxidize glucose oxidase necessary for the decomposing bacteria to oxidize glucose, and can also directly react with bacteria and viruses, so as to destroy the metabolism and the propagation process of the bacteria. In addition, ozone can oxidize various odorous inorganic or organic substances, and for example, ozone can decompose odorous gases such as ammonia, benzene, hydrogen sulfide, and the like, thereby performing a deodorizing function. The time for sterilizing, disinfecting and deodorizing ozone is short, and the effect is strong.

Wherein, the cover plate 21 can be made of plastic. In some embodiments, the cover plate 21 may also be made of quartz. The specific material of the cover plate 21 is not limited herein. The cover plate 21 may have a bowl shape, the coil assembly 22 is fixed on the inner wall 211 of the cover plate 21, and the coil assembly 22 is connected with the housing. The coil assembly 22 is disposed between the cover plate 21 and the housing, and ozone generated when the coil assembly 22 operates is blocked by the cover plate 21, so that the ozone is not easy to overflow out of the purification assembly 20, thereby protecting users to a certain extent.

Referring to fig. 3 and 4, in some embodiments, the cover plate 21 is provided with a plurality of spacers 212, the spacers 212 are formed with mounting holes 2121, the coil assembly 22 includes a mounting post 221 and a coil 222 wound around the mounting post 221, and the mounting post 221 is mounted on the mounting hole 2121. Thus, the coil assembly 22 is mounted on the mounting hole 2121, so that the structure of the purification apparatus 100 can be more compact, which is beneficial to the miniaturization of the purification apparatus 100.

Specifically, the arrangement of the plurality of spacers 212 on the inner wall 211 of the cover plate 21 may increase the rigidity of the cover plate 21. The mounting post 221 may be wound with a plurality of turns of the coil 222, and the mounting post 221 may be cylindrical. The number of the mounting holes 2121 may be plural. In one example, the two oppositely disposed spacers 212 each have a mounting hole 2121 formed therein, and both ends of the mounting post 221 in the axial direction of the mounting post 221 are respectively engaged with the two mounting holes 2121, so that the mounting post 221 can be limited to prevent the coil assembly 22 from falling off.

Referring to fig. 3 and 4, in some embodiments, the plurality of spacers 212 and the cover plate 21 form a mounting groove 213, the purification assembly 20 includes a transformer 23, the transformer 23 is electrically connected to the coil assembly 22, and the transformer 23 is disposed in the mounting groove 213. Thus, the transformer 23 is mounted in the mounting groove 213 of the cover plate 21, so that the structure is more compact, which is advantageous for miniaturization of the purification module 20.

Besides, the spacers 212 are used for installing and fixing the coil assembly 22 and increasing the rigidity of the cover plate 21, the spacers 212 may also form an installation groove 213 with the inner wall 211 of the cover plate 21 for placing the transformer 23. The shape of the mounting groove 213 may be rectangular, circular, etc., and the shape of the mounting groove 213 is not limited herein. In one example, the transformer 23 can be fixed to the inner wall 211 of the cover plate 21 by bonding, so as to prevent the transformer 23 from falling off from the mounting groove 213 and affecting the working efficiency of the purification apparatus 100. It is understood that the transformer 23 and the mounting groove 213 of the cover plate 21 can be connected by a snap-fit manner, and the mounting manner of the transformer 23 and the cover plate 21 is not limited herein.

More specifically, the transformer 23 and the coil block 22 may be electrically connected by a wire, so that the transformer 23 transforms and transmits a standard voltage, which is most commonly used by residents, to the coil block 22, thereby forming the coil block 22 with an operating voltage to generate ozone. The purpose of transformation can be achieved by changing the turns ratio of the inductor 222 inside the transformer 23. In some embodiments, the outer layer of the transformer 23 may be covered with a resin, thereby serving to protect the transformer 23 and improve the performance of the transformer 23.

Referring to fig. 3 and 4 again, in one example, the number of the coil assemblies 22 is two, and two coil assemblies 22 may be respectively disposed on two opposite sides of the transformer 23. In this way, the two coil assemblies 22 are respectively disposed at two opposite sides of the transformer 23, so that the ozone generated by the two coil assemblies 22 is uniformly distributed.

Specifically, the coil assembly 22 and the transformer 23 are separated by the partition 212, so that the purification assembly 20 is beautiful and compact in appearance as a whole, which is beneficial to miniaturization of the purification apparatus 100. In some embodiments, the number of the coil assemblies 22 may also be three, four, or more, and is not limited herein. The number of the coil assemblies 22 can be multiple, the coil assemblies 22 can be arranged around the transformer 23, and the multiple coil assemblies 22 can enhance the efficiency of the purifying assembly 20 for ionizing air to generate ozone, thereby improving the purifying capability of the purifying device 100 for lampblack.

Referring to fig. 3 and 4, in some embodiments, the cover plate 21 is formed with a through hole 214 communicating with the accommodating space 30. In this way, the ozone generated by the purifying assembly 20 can flow out through the through holes 214, and further sterilize, disinfect and deodorize the oil smoke.

Specifically, a plurality of through holes 214 may be formed at intervals on the cover plate 21, air may flow through the through holes 214 to the through holes 214 formed on the cover plate 21 to enter the inside of the purification assembly 20, and after the coil assembly 22 ionizes the air into ozone, the ozone may flow out through the through holes 214 to purify the oil smoke.

Referring to fig. 3 and 4, in some embodiments, the through hole 214 is aligned with the coil assembly 22 along the depth direction of the through hole 214. Therefore, ozone generated after the coil assembly 22 is powered on can rapidly pass through the through holes 214 and purify the oil smoke, and the purification efficiency of the purification assembly 20 on the oil smoke is further improved.

Specifically, the coil block 22 is visible through the through hole 214 from the side of the cover plate 21 facing away from the second case 12. The number of the through holes 214 may be plural. In one example, four through holes 214 are formed in the cover plate 21, and each two through holes 214 are in a group, and the number of the coil assemblies 22 is equal to that of the through holes 214 in each group, and the through holes 214 in each group are respectively aligned with the coil assemblies 22. In this case, two through holes 214 among a set of through holes 214 may perform convection, wherein one through hole 214 is an air inlet and the other through hole 214 is an air outlet for ozone, thereby increasing the rate at which air is converted into ozone and oil smoke is purified.

Referring to fig. 1, 2 and 5, in some embodiments, the housing 10 includes a first shell 11 and a second shell 12 detachably connected to the first shell 11, the second shell 12 and the first shell 11 together form a receiving space 30, and the purifying assembly 20 is received in the receiving space 30.
