Embodiment

[0040] As shown in FIG. 1, the present invention sets forth a purifier, which includes a purifier body 100 and a filter unit 200. The filter unit 200 is an integrated disinfection and purification body, which is mounted into the purifier body 100 from an opening on a side wall of a purification chamber 110 of the purifier body 100 to purify and disinfect air.

[0041] As shown in FIG. 1, the purifier body 100 has a purification chamber 110. The purification chamber 110 is located in the lower half of the purifier body 10. The side wall of the purifier body 100 has an opening to form a side opening structure. The opening is in communication with the purification chamber 110. A cover 120 is mounted at the opening. The cover may be connected to the opening by means of snap-fitting, magnetic attraction, hinging, etc., which is a common technology in the field of purifiers and will not be described in detail here.

[0042] A plurality of air inlet holes are provided in the side wall of the purifier body 100 corresponding to the purification chamber 110 or in the cover 120 to form an air intake passage, and the purifier body 100 has a purified air discharge passage.

[0043] In addition, the purifier body 100 is provided with a second electrical connector (not shown) which can be connected to a power supply, and the second electrical connector may be a plug which can be connected to a power socket to realize the connection between the purifier body and the power supply. Alternatively, the second electrical connector may be a wireless electrical component or a conductor connected to a built-in battery.

[0044] As shown in FIGS. 1 and 3, the filter unit 200 is cylindrical and mounted into the purification chamber 110 from the opening, and the cover 120 is mounted at the opening to realize the installation of the filter unit 200. When the filter unit 200 is mounted inside the purification chamber 110, a first electrical connector 230 provided at the bottom of the filter unit 200 is mated and connected to the second electrical connector to activate the filter unit 200, i.e., to supply power to the filter unit 200. In addition, air enters the air intake passage, is purified by the filter unit 200, and is then discharged from a purified air outlet at the upper end of the purification unit 200 and the air discharge passage of the purifier body 100. The purified air outlet is an opening at the upper end of the purification unit 200, and is in communication with the air discharge passage.

[0045] As shown in FIGS. 1-6, the filter unit 200 includes a filter body 210 and a disinfection body 220. The filter body 210 is in an annular shape, the disinfection body 220 is located in the filter body 210, and the filter body 210 is detachably mounted to the disinfection body 220 to form an integrated structure with the two bodies detachable from each other. The disinfection body 220 is provided with a mounting seat 222 on which an ultraviolet disinfection lamp 221 is vertically mounted, and at least one rotational snap-fit notch 211 of the filter body 210 is rotationally snap-fitted with or detached from at least one rotational snap-fit catch 223 on the mounting seat 222, so as to achieve the purpose of replacing the filter body conveniently and improve the maintenance convenience of the purifier.

[0046] Specifically, as shown in FIGS. 2-6, the disinfection body 220 includes the ultraviolet disinfection lamp 221 and the mounting seat 222. The ultraviolet disinfection lamp 221 is vertically mounted at the center of the mounting seat 22, and a first electrical connector 230 is arranged at the center of a bottom surface of the disinfection body 220, and the first electrical connector 230 is a conductive contact. An inner side wall of the filter body 210 is provided with the at least one rotational snap-fit notch 211, and an outer side wall of the mounting seat 222 is provided with the at least one rotational snap-fit catch 223. In this embodiment, there are a plurality of the rotational snap-fit notches 211 arranged at intervals. The number and positions of rotational snap-fit catches 223 match the number and positions of the rotational snap-fit notches 211.

[0047] In this embodiment, as shown in FIGS. 4-6, the rotational snap-fit notches 211 are located at a lower edge of the inner side wall of the filter body 210, and the rotational snap-fit catches 223 are located at the outer side wall of the mounting seat 222. There are four rotational snap-fit notches 211 and four rotational snap-fit catches 223, which are all arranged at intervals. The filter body 210 surrounds the outside of the disinfection body 220 and is rotated such that the rotational snap-fit notches 211 are mated and snap-fitted with the rotational snap-fit catches 223 to realize the connection between the disinfection body 220 and the filter body 210. On the contrary, the disinfection body 220 and the filter body 210 are rotated relative to each other such that the rotational snap-fit notches 211 are detached from the rotational snap-fit catches 223, so as to detach the disinfection body 220 from the filter body 210, so that the filter body 210 can be conveniently replaced on a regular basis.

[0048] Referring to FIG. 1 and FIGS. 4-6, in order to accurately mount the disinfection and filter body 200 in the purification chamber 110, a mounting limiting structure is arranged between the disinfection and filter body 200 and the purification chamber 110. The mounting limiting structure includes at least one limiting boss 240 and at least one limiting column 130. There are four of the limiting bosses 240, which are divided into two groups each including two limiting bosses, the two groups of limiting bosses 240 are symmetrically arranged, and the two limiting bosses 240 in each group are arranged one above the other. The two limiting bosses 240 in each group are respectively located at upper and lower edges of the filter body 210. The at least one limiting column 130 is an upright column and is mounted in the purification chamber 110. There are two of the limiting columns, which match the two groups of limiting bosses 240. An outer side wall of each limiting boss 240 has a limiting face, which abuts against a side wall of a respective limiting column 130.

[0049] As shown in FIGS. 2-6, the filter unit 200 is provided with a handle 250. The handle 250 is located at the upper edge of the filter body 210.
