Referring to fig. 1-5, the present invention provides a technical solution:

the utility model provides an air purification device of two air intakes, includes shell 1, has seted up cavity 11 in the shell 1. Two air inlet ports 2 communicated with the cavity 11 are formed in the side wall of the shell 1 and close to the lower end. A circular groove 21 is formed in one end, close to the outside, of the circumferential wall of the air inlet opening 2, and a primary filter screen 3 is arranged in the circular groove 21. The circumference wall that just is located air inlet opening 2 of one side of filter screen 3 vertically is a plurality of fixed slots 22 of having seted up of annular equidistant range, is equipped with motor 4 in the air inlet opening 2. The circumferential wall of the motor 4 is provided with a plurality of fixing blocks 41 which are arranged in a ring shape at equal intervals, and the fixing blocks 41 are clamped in the fixing grooves 22. The output shaft of the motor 4 is positioned in the cavity 11, and a plurality of fan blades 5 which are arranged in an annular and equidistant mode are arranged at one end of the output shaft of the motor 4. And a particle filter screen 6 is arranged at one end of the air inlet port 2, which is communicated with the cavity 11. A first returning groove 12 and a second returning groove 13 are sequentially arranged in the cavity 11 from bottom to top. A composite screen 14 is disposed within the first backset groove 12. The composite filter screen 14 can effectively remove formaldehyde and peculiar smell. The second returns and is equipped with the filter screen 15 that disinfects in the groove 13, and a large amount of bactericides can effectively be killed to the filter screen 15 that disinfects, and a plurality of ventholes 16 that are the matrix and arrange are seted up to shell 1 and the relative one side of air inlet opening 2. The air outlet holes 16 facilitate the rapid release of fresh air. The air outlet 16 is positioned above the second return groove 13, so that the feet of people are prevented from accidentally kicking the air outlet 16, and sand and other substances enter the cavity 11 to damage the sterilizing filter screen 15. The universal wheels 17 are arranged at the four corners of the bottom surface of the shell 1, so that the whole device can be moved conveniently.

Specifically, the size of circular groove 21 and the size looks adaptation of prefiltration net 3, and prefiltration net 3 passes through the screw and is fixed with circular groove 21. The stability of structure is guaranteed, and the installation and the dismantlement are convenient for simultaneously. The motor 4 in the air inlet port 2 is easily replaced, the diameter of the meshes of the primary filter net 3 is 0.1cm, and substances such as hair and fine scraps are effectively filtered.

Further, the size of the fixing block 41 is matched with the size of the fixing groove 22. When the motor damages, can hold between the fingers the outside removal of motor 4 by hand, make fixed block 41 move to the external world in fixed slot 22, be convenient for take out motor 4, and fixed block 41 and fixed slot 22 are pegged graft the cooperation, and the quantity of fixed block 41 and fixed slot 22 is 4 at least, at motor 4 during operation, guarantees motor 4's stability.

Specifically, the cross-sectional diameter of the motor 4 is smaller than the diameter of the air inlet 2. Enable a large amount of air and gush into air inlet opening 2, motor 4 output shaft and flabellum 5 are integrated into one piece structure, guarantee the stability of structure, and the quantity of flabellum 5 is 3 at least. Guarantee that motor 4 output shaft drives flabellum 5 when rotatory, can inhale air inlet opening 2 fast with indoor a large amount of air, purify indoor air fast, make the efficiency of its work improve greatly, alright when shortening motor 4's use long.

Furthermore, the particle filter screen 6 is tightly adhered to the air inlet port 2, so that the stability of the structure is ensured, and the diameter of the meshes of the particle filter screen 6 is 0.02-0.05cm, so that tiny granular substances can be filtered.

Further, the first return groove 12 is sized to accommodate the size of the composite screen 14. The size of the second return groove 13 is matched with that of the sterilizing filter screen 15. The air is prevented from passing through the first and

second return grooves

12 and 13, resulting in unfiltered air.

It is worth to be noted that the motor 4 related in the utility model adopts a motor with model number RS-365 produced by Shenzhen Hua Chuangsheng Motor Limited; in addition, the motor 4 related to the present invention is prior art, and can be implemented by those skilled in the art, and it is needless to say that the present invention also does not relate to the improvement of the structure and working principle of the motor 4.

When the air purification device with the double air inlets is used, the motors 4 in the two air inlet openings 2 are simultaneously switched on, the output shafts of the motors 4 drive the fan blades 5 to rotate, a large amount of indoor air is sucked into the air inlet openings 2, meanwhile, hair, fine scraps and other substances are filtered through the primary filter screen 3, then the fan blades 5 rotate to blow air, the air filters tiny granular substances through the particle filter screen 6 until the air enters the cavity 11, then the air upwards passes through the composite filter screen 14 and the sterilization filter screen 15 to remove formaldehyde, peculiar smell and bacteria under the thrust of the fan blades 5 rotating to blow air, finally, the fresh air is sent to the outside through the air outlet holes 16, when the two motors 4 simultaneously drive the fan blades 5 to rotate, the indoor air can be rapidly changed into the fresh air, the air purification efficiency is greatly improved, the service life of the motors 4 is shortened, the service life of the motor 4 is increased.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
