Detailed Description

The present invention will be described in detail with reference to fig. 1 to 6, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present invention provides an air cleaner, as shown in fig. 1 to 6, and referring to fig. 1, 2 and 3, by improvement, which includes an upper case 11, a housing 12, a base 13, a motor 21, an air guide wheel 22, a blowing part 30, and a filter layer 40 for purifying air.

Specifically, an air outlet 111 is formed in a side surface 11a of the upper shell 11, and the air purified by the filter layer 40 is conveyed to the outside through the air outlet 111, wherein the upper shell 11 includes four side surfaces 11a formed by splicing and enclosing, and the air outlets 111 are formed in the four side surfaces 11 a. A control panel 112 is provided on the upper case 11 so that a user can manually input operating parameters of the air purifier.

Referring to fig. 6, an air inlet 121 is formed in a side surface 12a of the housing 12, the upper housing 12 includes four side surfaces 12a formed by splicing and enclosing, the air inlets 121 are formed in the four side surfaces 12a, air around the housing 12 is sucked into the air purifier through the air inlets 121 formed in the side surfaces 12a, is purified through the filter layer 40, and is discharged through the air outlet 111 formed in the upper housing 11.

The housing 12 is connected to the base 13 to form a space for accommodating the motor 21, the wind wheel 22 and the air supply component 30, the base 13 is provided with an air inlet 131, the motor 21 is fixedly arranged on the base 13, the motor 21 is connected to the wind wheel 22, the motor 21 drives the wind wheel 22 to rotate, the wind wheel 22 is arranged opposite to the air inlet 131 to actively suck external air into the air purifier from the air inlet 131, and push the sucked space to be sequentially conveyed to the air supply component 30 and the filter layer 40, and the air is conveyed outwards from the air outlet 111 after being purified by the filter layer 40, so as to meet the requirement of a user on fresh air.

In order to suck and introduce the air around the shell 12 into the air purifier without additionally arranging a motor and an air guide wheel on the side surface, improve the purification range and the purification performance of the air purifier and reduce the cost and the power consumption of the air purifier, the air supply part 30 is arranged in the air purifier.

Specifically, referring to fig. 4 and 5, the air supply component 30 includes an air supply port 31, an air suction port 32 and an air outlet port 33. The air supply port 31 is disposed opposite to the air guide wheel 22, and the air guide wheel 22 conveys air sucked from the air inlet 131 into the air supply port 31. The air outlet port 33 is disposed opposite to the filter layer 40, so that air is delivered from the air outlet port 33 into the filter layer 40.

The circular truncated cone-shaped air supply port 31 comprises a first air supply end 311 and a second air supply end 312, the aperture of the second air supply end 312 is smaller than that of the first air supply end 311, the circular truncated cone-shaped air outlet port 33 comprises a first air outlet 331 end and a second air outlet 332 end, the aperture of the second air outlet 332 end is larger than that of the first air outlet 331 end, the second air supply end 312 is connected with the first air outlet 331 end through a straight pipe 34, and preferably, the end part of the straight pipe 34 is respectively connected with the second air supply end 312 and the first air outlet 331 end in a welding mode. Thus, the air entering from the air supply port 31 and flowing out of the air outlet port 33 sequentially passes through: the first air supply end 311, the second air supply end 312, the straight pipe 34, the first air outlet 331 end and the second air outlet 332 end are finally conveyed into the filter layer 40 by the second air outlet 332 end. Further, the air supply port 31, the straight tube 34 and the air outlet port 33 are coaxially disposed, and the aperture size of the second air supply end 312 is equal to that of the first air outlet end 331.

The four air suction ports 32 are uniformly arranged along the circumferential direction of the straight tube 34 and are communicated with the straight tube 34, that is, the four air suction ports 32 are arranged at an angle of 90 ° with each other, one end of the air suction port 32 is communicated with the straight tube 34, and the other end thereof is arranged opposite to and communicated with the air inlet 121, so that the air on the side surface of the housing 12 is sucked into the air cleaner through the air suction port 32.

Furthermore, after the air enters the air supply component 30 through the air inlet 131 on the base 13, sequentially passes through the first air supply end 311 and the second air supply end 312 of the air supply port 31, the straight pipe 34 and the first air outlet 331 end and the second air outlet 332 of the air outlet port 33, since the aperture of the second blowing end 312 is smaller than that of the first blowing end 311, and the aperture of the second blowing end 332 is larger than that of the first blowing end 331, therefore, when the air flows through the internal structure of the air supply part 30, the cross section of the air flowing through changes from decreasing to increasing, and as can be known from the aerodynamics and the venturi tube principle, the air forms negative pressure in the straight pipe 34, forms pressure difference with the air in the external environment, further, the air in the air inlet 121 corresponding to the air suction port 32 communicated with the straight tube 34 is sucked into the straight tube 34, and are pushed by the air in the straight pipe 34 to be jointly conveyed to the filter layer 40 through the air outlet port 33. Thereby realizing the suction of the air at the side of the shell 12 and further improving the purification performance and the purification range of the air purifier.

The filter layer 40 includes a primary filter layer 41, a high-efficiency filter layer 42 and an activated carbon filter layer 43, the primary filter layer 41 is connected to the housing 12, the high-efficiency filter layer 42 is disposed between the primary filter layer 41 and the activated carbon filter layer 43, and the activated carbon filter layer 43 is connected to the upper housing 11, so that air entering from the air inlet 131 and the air inlet 121 is gradually filtered and purified by the primary filter layer 41, the high-efficiency filter layer 42 and the activated carbon filter layer 43 under the pushing action of the wind guide wheel 22 and then is transported to the outside through the air outlet 111.

Specifically, the primary filter layer 41 is used for primarily filtering the air to remove large suspended particles such as hair and dust in the air, so as to prevent the filter layer 40 from being blocked or damaged by the large suspended particles such as hair and dust in the air. The high efficiency filter layer 42 is used to remove ultra fine particulate contaminants such as allergens in the air (pollen, dust mites or mold, etc.) as well as bacteria or viruses. The activated carbon filter layer 43 can efficiently adsorb harmful substances such as formaldehyde and the like, and effectively remove peculiar smell in the air.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
