Further, in the embodiment of fig. 5, the bracket 3 is a U-shaped structure, which includes a bottom plate 30 and a first side plate 31 and a second side plate 32 located at both sides of the bottom plate 3, the bottom plate 30 is attached to the top surface of the air cleaner 1, where the bottom plate 30 and the top surface of the air cleaner 1 may be connected by a fastener; and the length of the bottom plate 30 matches the size of the top surface of the air cleaner 1, and the first side plate 31 and the second side plate 32 of the bracket 3 are respectively caught at two opposite side surfaces of the air cleaner 1 to be connected thereto.

Further, first curb plate 31 with the distal end portion of second curb plate 32 sets up first joint portion 33 and second joint portion 34 respectively, like this, work as air cleaner 1 exhaust end 11 with admission valve 2 the back is pasted tightly, will support 3 is detained air cleaner 1's top, support 3 the bottom plate 30 first curb plate 31 and second curb plate 32 respectively with air cleaner 1's corresponding face is close to, and passes through first joint portion 33 with second joint portion 34 will air cleaner 1 block is in on admission valve 2.

Further, as shown in fig. 4, two opposite bosses 22 are provided under the end surface of the intake end 21 of the intake valve 2, and the first and second engaging portions 33, 34 located at the distal end portions of the first and second side plates 31, 32 are connected to the corresponding bosses 22 by fasteners 36, for example, the first and second engaging portions 33, 34 are engaged with the lower edges of the bosses 22. The fasteners 36 may be bolts, for example. Not only will like this through first joint portion 33 with second joint portion 34 air cleaner 1 block is in on the admission valve 2, can also pass through fastener 36 realizes fixing, makes air cleaner 1 with the connection between the admission valve 2 is inseparable, prevents to appear leaking the condition.

Further, in order to avoid wasting the effective filtering area of the air cleaner 1, as shown in fig. 5, through holes 35 are formed in the first side plate 31 and/or the second side plate 32 of the bracket 3, where the number and arrangement of the through holes 35 are not limited, for example, at least one through hole 35 may be sequentially arranged along the length direction of the first side plate 31 and/or the second side plate 32.

After the air intake assembly of the embodiment of the present disclosure is installed on the air compressor, in the process of air compression, the air intake valve 2 opens the valve plate after receiving an opening signal sent by a controller, and the air is filtered by the air filter 1 to block dust outside the air compressor; the filtered clean air enters the air compressor through the air inlet valve 2 to be compressed, so that air with a predetermined pressure is provided for a user.

A second embodiment of the present disclosure relates to an air compressor, which may be, for example, a screw compressor, and includes the intake assembly of any of the embodiments, wherein the exhaust end 23 of the intake valve 2 of the intake assembly is connected to the intake port of the air compressor.
