At present, traditional air purifier is by blower fan in air intake clarifier, then by various filter screen, negative ion generating device etc. will be discharged after air filtration; The suction of air, by the process of filter screen and discharge and clarifier inwall, blower fan etc. produce fierce friction, produce various very large noise.Have a strong impact on the rest of user person and spiritual damage night.
Utility model content:
For the problems referred to above, the utility model will provide a kind of quiet air purifier, effectively solves shortcomings and deficiencies of the prior art; Increase noise reduction vibrationproof sealing ring by the quiet blower fan of new reasonable air inlet, low speed Wind Volume, blower fan and air purifier installation place, the air outlet without air flowing eddy current sound of noiselessness electrostatic air purification techniques and advanced person designs, effectively reach the muting function of air purifier, practical.
The quiet air purifier of the one that the utility model provides, fresh air inlet is arranged on whole disc, can ensure omnibearing air inlet effect all the time, and omnibearing air intake effectively reduces air intake noise; Adopt the induced-draught fan of the large normal angle blade of the slow-speed of revolution, greatly reduce the fricative of Air suction blower blade; The inwall of induced-draught fan surrounding and air purifier installs noise reduction vibrationproof sealing ring, prevents the air sucked from pouring in down a chimney, effectively absorbs the noise of machine operation, eliminates the noise of cross-ventilation generation and the vibrating noise of fan operation; The collecting cover that air inlet is provided with orthodrome design improves the air draught efficiency of induced-draught fan and reduces flow resistance and the noise of air; Before the purification that induced-draught fan sucks, air is by after noiseless electrostatic purification techniques purification, and a point two-way enters U-shaped air outlet and discharges; Arrange fixed guide vane at air outlet, the air after purification is that fixed-direction is dispersed and sent, and reduces air jet-stream whirl sound; Air exhausting structure is U-shaped profile, and inner flow passage damping is little, can reduce noise when equipment runs.
The advantage of this project, the quiet air purifier of described one, air inlet is the hole of circumference uniform distribution, comprehensive air inlet; Induced-draught fan adopts the large normal angle blade of the slow-speed of revolution, ensures air inlet suction air volume when reducing blower fan running noise; Junction installed by induced-draught fan increases noise reduction vibrationproof sealing ring, prevents the air sucked from pouring in down a chimney, effectively absorbs the noise of machine operation, eliminates the noise of cross-ventilation generation and the vibrating noise of fan operation; Air inlet path between air inlet and induced-draught fan is provided with the collecting cover of orthodrome design, improves the air draught efficiency of induced-draught fan and reduces flow resistance and the noise of air; Air cleaning unit adopts noiseless electrostatic purification techniques; Arrange fixed guide vane at air outlet, the air after purification is that fixed-direction is dispersed and sent, and reduces air jet-stream whirl sound; Air exhausting structure is U-shaped profile, and inner flow passage damping is little, can reduce noise during air flowing.
The beneficial effects of the utility model are: it is comprehensive that air inlet is designed to circumference, and omnibearing air inlet effectively reduces the noise of air inlet; And the collecting cover of orthodrome design is installed, reduce flow resistance and the frictional force of air inlet, reduce noise; Adopt the slow-speed of revolution and Plane of rotation and blade normal angle to be the induced-draught fan of 30 degree, while ensureing intake, lower the friction of fan blade and air, reduction noise; Increase noise reduction vibrationproof sealing ring installed out by induced-draught fan, effectively absorbs and counteract running noise and the vibrating noise of induced-draught fan; Arrange fixed guide vane at air outlet, the air after purification is that fixed-direction is dispersed and sent, and reduces air jet-stream whirl sound; Air exhausting structure is U-shaped profile, and inner flow passage damping is little, can reduce noise during air flowing; Air cleaning unit adopts noiseless electrostatic purification techniques, and effective destruction Sum decomposition toxic and harmful molecule, moisture is evaporated, and microorganism is carbonized, and keeps room air fresh.
Accompanying drawing illustrates:
For ease of illustrating, the utility model has following concrete enforcement pole accompanying drawing as detailed description.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the explosive view in the utility model in detailed description of the invention.
1-air admission hole; 2-induced-draught fan; 3-sealing ring; 4-U shape air outlet; 5-collecting cover; 6-fixed guide vane sheet; 7-electrostatic type air purification apparatus; 8-shell one.
Detailed description of the invention:
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the concrete case study on implementation shown in accompanying drawing, the utility model is described.But these describe a just example, and do not really want to limit scope of the present utility model and limitation.In addition, in the following description, eliminate the description to known features and technology, avoided unnecessary fuzzy or twist concept of the present utility model.
As shown in Figure 1-2: the utility model adopts technical scheme: it comprises air admission hole 1, induced-draught fan 2, sealing ring 3, U-shaped air outlet 4, collecting cover 5, fixed guide vane sheet 6, electrostatic type air purification apparatus 7, shell 1, air admission hole 1 is arranged on shell 1 disc, can ensure omnibearing air inlet effect and the noise effectively reducing air inlet all the time; In shell 1, collecting cover 5 is installed, is connected with air admission hole 1 bayonet socket; Collecting cover 5 air intake duct is orthodrome, reduces flow resistance and the frictional force of air inlet, reduces noise; Collecting cover 5 inner end is connected with induced-draught fan 2 bayonet socket, the inwall sealing ring 3 of induced-draught fan 2 surrounding and shell 1 seals, effectively absorb the noise of machine operation, eliminate the noise of cross-ventilation generation and the vibrating noise of fan operation, prevent the air sucked from pouring in down a chimney; Before the purification that induced-draught fan 2 sucks, air is by after noiseless electrostatic type air purification apparatus 7 purified treatment, and a point two-way enters U-shaped air outlet 4 and discharges; Arrange fixed guide vane sheet 6 at U-shaped air outlet 4, the air after purification is that fixed-direction is dispersed and sent, and reduces air jet-stream whirl sound; U-shaped air outlet 4 structure is U-shaped profile, and inner flow passage damping is little, can reduce noise when equipment runs.
