[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a double-layer dustproof net composite device, comprising a base and a double-layer net assembly, a double-layer net assembly is arranged at the top of the base, and a composite net assembly is arranged inside the double-layer net assembly, a detachable assembly is arranged at the top of the double-layer net assembly, the double-layer net assembly comprises a first dustproof net and a second dustproof net, and the second dustproof net is arranged at the bottom end of the first dustproof net.

[0006] Furthermore, the base and the double-layer net component are embedded in each other, and the double-layer net component and the detachable component are in close contact with each other.

[0007] Furthermore, the double-layer net component is detachably connected to the base via a detachable component, and the detachable component and the base are snap-fitted.

[0008] Furthermore, the first dustproof net and the second dustproof net are of the same size, and the internal grid patterns of the first dustproof net and the second dustproof net are staggered.

[0009] Furthermore, the composite mesh component includes a pre-filter layer, a filter layer and an activated carbon layer, and the filter layer is disposed on one side of the pre-filter layer, and the activated carbon layer is disposed on one side of the filter layer.

[0010] Furthermore, the pre-filter layer and the filter layer are in contact with each other, and the filter layer and the activated carbon layer are coordinated with each other.

[0011] Furthermore, the detachable component includes a top cover, a buckle slot, a locking rod, a fixed bottom and a support slot, and a buckle slot is provided on one side of the top cover, a locking rod is provided at the bottom end of the top cover, and a fixed bottom is provided at the bottom end of the locking rod, and a support slot is provided at the connection between the fixed bottom and the locking rod.

[0012] Furthermore, the top cover is snap-connected to the fixed bottom via a snap-connecting rod, and the snap-connecting rod is embedded in the supporting column slot.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Another set of second dust-proof nets is set at the bottom of the composite net assembly. The two additional sets of dust-proof nets perform double filtration of the air, changing the previous dust-proof composite net equipment to a single layer. After long-term use, the dust-proof net is easily clogged, which avoids the situation where the filtering effect of the dust-proof net is reduced and frequent replacement is required, thereby reducing the replacement frequency for users.

[0015] Smaller particles in the air will be adsorbed by the filter layer, ensuring a good filtering effect while preventing dust. The activated carbon layer can effectively adsorb harmful substances in the air, not only preventing dust, but also purifying the air. At the same time, it can effectively remove odors in the air, increasing the comfort of people's living environment.

[0016] The locking rod at the bottom end of the top cover is moved out from the support groove inside the fixed bottom to replace the double-layer net component. After the replacement is completed, the locking rod at the bottom end of the top cover is placed inside the four groups of support grooves inside the fixed bottom for locking. This is convenient for the user to quickly replace the double-layer net component when it is blocked, effectively ensuring the normal use of the double-layer net component, and has the advantages of simple structure and easy operation.
