Detailed Description

In order to make the above objects, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

In order to solve the problems of complex operation and low efficiency in the conventional air purifier that the air inlet grille needs to be thoroughly detached from the shell in the process of replacing the filter screen, and the air inlet grille is installed on the shell again after the outer filter screen is replaced, the air purifier of the embodiment can open the accommodating cavity arranged on the shell by arranging the first inserting part on the air inlet grille and arranging the second inserting part on the shell, and the first inserting part and the second inserting part can be rotatably and detachably inserted together, so that the air inlet grille rotates to the second position relative to the shell when the filter screen needs to be replaced, and the accommodating cavity on the shell can be shielded by rotating the air inlet grille to the first position relative to the shell after the filter screen in the accommodating cavity is replaced, thereby simplifying the process of replacing the filter screen, the efficiency of change filter screen is improved, simultaneously here, when needs wash air-inlet grille for when the relative shell of air-inlet grille moved the third position, make first grafting portion and second grafting portion break away from the grafting, can take off air-inlet grille from the shell, and then wash air-inlet grille.

As shown in fig. 1, 2, 3, 4 and 5, an embodiment of the present invention provides an air purifier including a housing 100, a filter 200, and an air grille 300. The air inlet grille 300 is used for the air flow outside the housing 100 to enter the housing 100 and then flow through the filter element 200, and specifically, an air flow driving member such as a fan may be provided to drive the air flow to enter the air inlet grille 300 and then flow through the filter element 200. In a possible example, the filter element 200 may be, for example, a filter screen or an activated carbon cartridge, the filter element 200 being intended for filtering air.

As shown in fig. 1, the housing 100 is provided with an accommodation chamber 101 along a thickness direction thereof, and the filter 200 is disposed in the accommodation chamber 101. The housing 100 is further provided with an opening communicating the inside and the outside of the accommodating chamber 101, and the filter member 200 is installed into the accommodating chamber 101 through the opening or removed from the accommodating chamber 101.

The air purifier of this embodiment, be provided with first grafting portion on the air-inlet grille 300, be provided with the second grafting portion on the shell 100, first grafting portion and the rotatable and detachable grafting of second grafting portion are in the same place, so that air-inlet grille 300 has the primary importance for shell 100, secondary importance and third position, at the primary importance, air-inlet grille 300 covers the holding chamber 101 that sets up on the shell 100, at the second place, air-inlet grille 300 opens the holding chamber 101 that sets up on the shell 100, at the third position, first grafting portion and second grafting portion can break away from the grafting, and then make air-inlet grille 300 and shell 100 separation.

When the air inlet grille 300 rotates to the second position relative to the housing 100, the air inlet grille 300 opens the accommodating cavity 101 formed in the housing 100, and at this time, parts in the accommodating cavity 101 of the housing can be repaired and replaced, for example, the filter element 200 in the accommodating cavity 101 can be replaced. When the air inlet grille 300 rotates to the first position relative to the housing 100, the air inlet grille 300 shields the accommodating cavity 101 formed in the housing 100, and at this time, the parts in the accommodating cavity 101 of the housing can be protected. When the air inlet grille 300 needs to be cleaned, the air inlet grille 300 can be rotated to a certain angle relative to the shell 100, and then the first inserting part and the second inserting part are separated by shaking, moving and other modes, so that the air inlet grille 300 is detached from the shell 100, and the air inlet grille 300 is cleaned conveniently.

The utility model discloses an air purifier, the rotatable and detachable grafting of second grafting portion that sets up on the first grafting portion that sets up on the air-inlet grille 300 and the shell 100 is in the same place, can make the relative shell 100 of air-inlet grille 300 at the primary importance, the air-inlet grille 300 covers the holding chamber 101 that sets up on the shell 100, at the second place, the holding chamber 101 on the shell 100 is opened to air-inlet grille 300, in the third place, first grafting portion and second grafting portion break away from grafting, and then make air-inlet grille 300 and shell 100 separate. Obviously, when needing to maintain and change spare part in the holding chamber 101, for example when changing the interior filtration piece 200 of holding chamber 101, need not to take off air inlet grille 300 whole from shell 100, and only need make air inlet grille 300 rotate to the second position relative to shell 100, can open holding chamber 101, maintain or change the spare part in holding chamber 101, after having changed or maintained spare part, also only need to make air inlet grille 300 rotate to the first position relative to shell 100, can cover holding chamber 101, so, make the process of maintenance or change spare part, and easy operation, efficiency improves. In addition, when the air inlet grille 300 needs to be cleaned, the air inlet grille 300 can be taken down from the housing 100 by separating the first inserting portion and the second inserting portion from inserting when the air inlet grille 300 relatively moves to the third position, and then the air inlet grille 300 is cleaned.
