Problems solved by technology

[0003] The impeller shaft of a traditional fan is fixed in its casing, and the impeller rotation is fixed on the impeller shaft. When the impeller rotates, the impeller shaft does not rotate, but a certain torque will be generated between the two, which will cause the impeller shaft to vibrate and easily damage the fan. Fan life is low

Embodiment Construction

[0017] Such as Figure 1-3 As shown, an air intake fan includes a housing 1100 , a bracket 1200 , a vibration isolation pad 1300 , an impeller shaft 1400 and an impeller 1500 .

[0018] Both sides of the casing 1100 have circular air inlets 1110 , and the front side of the casing 1100 has an air outlet 1120 .

[0019] The bracket 1200 includes two discs 1210, which are respectively fixed at the air inlets 1110 on both sides of the housing 1100, and the outer sides of the discs 1210 have pits 1211 adapted to the vibration isolation pads 1300, the pits There is an impeller shaft fixing hole 1212 in the middle of the bottom of 1211 .

[0020] Specifically, three fixing feet 1220 are uniformly and radially extended from the outer side of the tray body 1210 , and the ends of the three fixing feet 1220 are fixed to the edge of the air inlet 1110 .

[0021] Wherein, the disc body 1210 is triangular, and of course it can also be in other shapes.

[0022] In order to reduce the manu...

Abstract

An air intake fan comprises a shell, a support, shock insulation pads, an impeller shaft and an impeller. The two sides of the shell are provided with circular air inlets. The front side of the shell is provided with an air outlet. The support comprises two disk bodies. The two disk bodies are fixed to the air inlets in the two sides of the shell respectively. The outer side of each disk body is provided with a concave pit matched with the corresponding shock insulation pad. An impeller shaft fixing hole is formed in the middle of the bottom of each concave pit. The number of the shock insulation pads is two. The edges of the two shock insulation pads evenly extend outwards to form a plurality of embedded parts. A shock insulation hole is formed in the middle of each shock insulation pad and is in a gear shape. The two shock insulation pads are embedded in the concave pits of the two disk bodies respectively. The two ends of the impeller shaft penetrate through the shock insulation holes in the two shock insulation pads respectively and are fixed to the impeller fixing holes in the two disk bodies. The ends of the impeller shaft are provided with embedment parts corresponding to the shock insulation holes. The impeller is rotatably fixed to the impeller shaft. According to the air intake fan, shock of the impeller shaft can be buffered, so that the impeller shaft is not prone to damage, and the service life of the fan is prolonged.

Description

technical field [0001] The invention relates to a fan, in particular to an air intake fan. Background technique [0002] The fan is a kind of air intake equipment, which has been widely used in combined air conditioning units, fan boxes, fresh air units, waste heat recovery devices, etc. [0003] The impeller shaft of a traditional fan is fixed in its casing, and the impeller rotation is fixed on the impeller shaft. When the impeller rotates, the impeller shaft does not rotate, but a certain torque will be generated between the two, which will cause the impeller shaft to vibrate and easily damage the fan. Fan life is low. Contents of the invention [0004] Based on this, aiming at the above technical problems, an air intake fan is provided. [0005] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0006] A kind of air intake fan, including housing, bracket, vibration isolation pad, impe...
