Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a sound-insulating and noise-reducing heat-dissipating fan. Background Art

[0002] High-pressure fans, also called high-pressure blowers, are different from general centrifugal blowers. When the impeller rotates, due to the centrifugal force, the wind vane causes the gas to move forward and outward, thus forming a series of spiral movements. As the rotation proceeds, the kinetic energy of the gas increases, which further increases the gas pressure passing through the side channel. When the air reaches the connection point between the side groove and the discharge flange, the gas is squeezed out of the blades and discharged from the pump body through the outlet.

[0003] In the prior art, sound insulation panels and sound insulation covers are usually installed on the surface of the fan for sound insulation and noise reduction. In order to prevent dust and impurities in the air from entering the fan and causing fan blockage and excessive noise, a filter device is fixed on the surface of the air inlet pipe.

[0004] However, after long-term use, the filter device's surface will absorb fine debris such as dust in the air, and needs to be cleaned and replaced regularly. The filter device and the surface of the air inlet pipe are usually fixed with bolts, which makes disassembly troublesome and difficult to quickly replace and clean, and easily causes loud noise inside the fan. Utility Model Content

[0007] Preferably, a fixing plate is fixedly connected to the inner wall surface of the air inlet pipe, and the fixing plate has an annular plate structure. A rubber ring is fixedly connected to the surface of the fixing plate, and the rubber ring has a semicircular ring structure.

[0008] Preferably, the filter cartridge is in a tubular structure, a rubber groove is provided on the surface of one end of the filter cartridge, the rubber groove is an annular groove, and a rubber ring is clamped on the surface of the rubber groove.

[0009] Preferably, movable grooves are provided on both side surfaces of the air inlet pipe, and limiting grooves are provided on both side surfaces of the movable groove. The limiting grooves are square grooves, and sliding blocks are slidably connected to the surfaces of the limiting grooves.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
