Description

Technical Field

[0001] The invention relates to the technical field of magnetic suspension fans, and in particular to an air inlet device for a magnetic suspension fan. Background Art

[0002] A magnetic levitation fan is a mechanical device for conveying gas. It adopts core technologies such as magnetic levitation bearings, three-dimensional flow impellers, high-speed permanent magnet synchronous motors, high-efficiency inverter speed regulation, and intelligent monitoring and control. When starting, it first suspends and then rotates. It is frictionless and does not require lubrication. The three-dimensional flow impeller is directly connected to the rotor, and the transmission is zero-loss. It is a high-tech, green, energy-saving and environmentally friendly product. Due to the particularity of the working environment of the fan itself due to its own working characteristics, during the use of the fan, the air inlet end is mostly filtered out by grille filtering to avoid affecting the operating stability of the fan. After working for a long time, a large amount of impurities will be generated on the grille, affecting the ventilation effect of the grille, and then affecting the air intake of the fan. The external cleaning method cannot clean up the debris accumulated on the grille. At that time, the grille needs to be removed for cleaning. How to improve the convenience of disassembly while reducing the impact on the fan equipment, therefore, requires a magnetic levitation fan air inlet device. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an air intake device for a magnetically suspended fan, which is used to solve the problem of disassembly and cleaning of the air intake end grille in the prior art.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A magnetic levitation fan air intake device comprises a chassis, a fan is arranged in the chassis, a rear air intake frame is arranged on one side of the chassis, an air intake plate is detachably connected to the rear air intake frame, a wind plate buckle seat for supporting the air intake plate is arranged at the bottom of the rear air intake frame, a wind plate lock is rotatably connected to the upper side of the rear air intake frame, a lock paddle is arranged on the wind plate lock, a paddle slot is arranged on the rear air intake frame and below the wind plate lock, the lock paddle moves in the paddle slot as the wind plate lock rotates, and a sound insulation board is arranged in the chassis and between the rear air intake frame and the chassis.

[0006] To implement the above technical solution, a rear air inlet frame is provided on one side of the chassis, and an air inlet plate is detachably connected to the rear air inlet frame, so that the convenience of disassembly of the air inlet plate on the rear air inlet frame can be improved. The setting of the air plate buckle seat can provide stable support for the air inlet plate. The setting of the air plate lock can lock the air inlet plate installed on the air plate buckle seat. A paddle slot is provided on the rear air inlet frame and below the air plate lock, which can facilitate the locking paddle on the air plate lock to rotate in the paddle slot with the movement of the air plate lock. When the air inlet plate needs to be locked to the rear air inlet frame, the air plate lock can be moved to the bottom of the paddle slot by toggling the locking paddle to lock the air inlet plate. The setting of the sound insulation board can reduce the noise released from the rear air inlet frame and affect the surrounding working environment.

[0007] In one embodiment of the present invention, the rear air inlet frame is provided with two groups up and down on the chassis, the rear air inlet frame is provided with an air plate bracket supporting the air inlet plate and spaced apart from the bottom of the rear air inlet frame, and the bottom of the rear air inlet frame is provided with an air frame support rod.

[0008] To implement the above technical solution, by setting up two groups of rear air inlet racks, the air intake effect in the chassis can still be maintained after the air inlet plate on one group of rear air inlet racks is blocked. By setting up an air plate bracket to support the air inlet plate and the bottom spacing of the rear air inlet racks, the air intake effect can be guaranteed, the amount of air blocked by the rear air inlet racks can be reduced, and the air intake effect can be guaranteed.

[0009] In one embodiment of the present invention, the bottom of the sound insulation board is spaced apart from the bottom of the chassis.

[0010] The above technical solution is implemented to avoid the sound insulation board blocking the air intake at the rear air intake frame end.

[0011] In one embodiment of the present invention, the rear air inlet frame and the sound insulation board are spaced apart, and the spacing height is higher than the horizontal height of the central axis of the fan.

[0012] To implement the above technical solution, setting a spacing between the rear air inlet frame and the sound insulation board can improve the soundproofing effect of the sound insulation board and the air intake effect of the rear air inlet frame. Setting the spacing height higher than the horizontal height of the central axis of the fan can ensure the air intake volume at the rear air inlet frame end and ensure the operating stability of the fan.

[0013] In one embodiment of the present invention, an air intake frame covering the rear air intake frame is provided on the rear air intake frame, and the air intake frame is detachably connected to the chassis.

[0014] By implementing the above technical solution, the setting of the air intake frame can facilitate the installation and disassembly of the rear air intake frame, thereby improving the convenience of equipment use.

[0015] In one embodiment of the present invention, the air intake frame is an L-shaped frame, a frame groove is provided at the upper side of the chassis where it is connected to the air intake frame, and the short side end of the air intake frame is detachably connected to the frame groove.

[0016] By implementing the above technical solution, the provision of the frame groove can improve the installation convenience of the air intake frame and can also provide a limiting effect for the installation of the air intake frame.

[0017] In one embodiment of the present invention, the air plate lock protrudes from the air intake frame.

[0018] To implement the above technical solution, by setting the air plate lock buckle protruding from the air intake frame, the air intake plate can be easily removed after the closing plate lock buckle is rotated.

[0019] As described above, a magnetic levitation fan air inlet device of the present invention has the following beneficial effects: by providing a rear air inlet frame on one side of the chassis, and detachably connecting an air inlet plate to the rear air inlet frame, the convenience of disassembly of the air inlet plate on the rear air inlet frame can be improved, the setting of the air plate buckle seat can provide a stable supporting effect on the air inlet plate, the setting of the air plate lock can lock the air inlet plate installed on the air plate buckle seat, and a paddle slot is provided on the rear air inlet frame and below the air plate lock, which can facilitate the locking paddle on the air plate lock to rotate in the paddle slot with the movement of the air plate lock, and when the air inlet plate needs to be locked to the rear air inlet frame, the air plate lock can be moved to the bottom of the paddle slot by toggling the locking paddle to lock the air inlet plate, and the setting of the sound insulation board can reduce the noise released from the rear air inlet frame and affect the surrounding working environment.
