In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

An air purifier 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 4.

As shown in fig. 1 and 2, an air purifier 100 according to an embodiment of the present invention includes: the housing 1, volute 2 and motor 31 assembly.

Referring to fig. 1 and 2, an air inlet and an air outlet are formed on the housing 1, an air inlet grille 4 and a filter assembly 5 are arranged at the air inlet, and the filter assembly 5 is arranged on the inner side of the air inlet grille 4. The filter assembly 5 may filter air entering the air purifier 100. Alternatively, the air inlet holes of the air inlet grille 4 may be circular, but are not limited thereto. Specifically, air can enter the housing 1 through the air inlet, and after being filtered by the filter assembly 5, the air flows out of the air outlet. This can purify the air entering the air purifier 100, thereby improving the air quality.

Here, it should be noted that the "inner" direction in the present application refers to a direction near the center of the housing 1.

The volute 2 is disposed in the housing 1, the volute 2 defines an air duct therein, the air duct has an air duct inlet 21 and an air duct outlet 22, the air duct inlet 21 is communicated with the air inlet, the air duct inlet 21 is disposed on a side wall (e.g., a front side wall in fig. 2) of the volute 2 adjacent to the air inlet, and the air duct outlet 22 is communicated with the air outlet. The motor 31 assembly comprises a motor 31 and a wind wheel 32, the motor 31 is arranged on the volute 2, the wind wheel 32 is connected with a motor shaft 310 of the motor 31, and the wind wheel 32 and the air inlet grille 4 are respectively positioned at two sides of the volute 2. For convenience of description, the installation mode in which the wind wheel 32 and the air-inlet grille 4 are respectively located at both sides of the scroll casing 2 is defined as "motor 31 is located forward", and the installation mode in which the wind wheel 32 and the air-inlet grille 4 are located at the same side of the scroll casing 2 is defined as "motor 31 is located backward".

From this, through installing wind wheel 32 and air inlet grid 4 respectively in the both sides of spiral case 2 (being about to motor 31 leading), can directly set up wind channel entry 21 on the lateral wall of spiral case 2, for the mounting means (being the motor rearmounted) of installing wind wheel and air inlet grid in the same side of spiral case among the correlation technique, the grid board that is used for setting up wind channel entry 21 has been omitted, air purifier 100's structure has been simplified, air purifier 100's spare part quantity and air purifier 100's thickness have been reduced to air purifier 100's volume has been reduced.

Meanwhile, the installation mode of the front motor 31 does not need to arrange a protruding part used for yielding the motor 31 in the middle of the wind wheel 32, so that the size of the wind wheel 32 is reduced, the size of the air purifier 100 is further reduced, the phenomenon that the protruding part blocks airflow when air enters the wind wheel 32 through the volute 2 is avoided, and the load air volume of the air purifier 100 is improved. Research shows that under the same rotating speed, the front load air volume of the motor 31 is about 20% higher than the rear load air volume of the motor 31. In addition, compared with the rear mounting mode of the motor 31, when the motor 31 is arranged in the front, the center of gravity of the whole air purifier 100 is closer to the center line of the whole air purifier, and the stability of the air purifier 100 is effectively improved.

For example, in some embodiments of the present invention, referring to fig. 2, the rear side of the scroll casing 2 is open, and the duct inlet 21 is provided on the front side wall of the scroll casing 2. The motor 31 can be fixed on the volute 2 through the motor fixing frame 311 and the second screw, and the wind wheel 32 can be arranged on the motor shaft 310 in a penetrating manner and locked by a nut. The wind wheel 32 may be located at the rear side of the motor 31.

Wherein, the wind wheel 32 and the air inlet grille 4 are respectively positioned at two sides of the volute 2. Referring to fig. 2, the wind wheel 32 is located at the rear side of the scroll casing 2, and the air-inlet grill 4 is located at the front side of the scroll casing 2.

In the description of the present invention, it is to be understood that the terms "front", "rear", "top", "inner", "outer", "circumferential", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
