The utility model is related to domestic electric appliance technical fields, and in particular to a kind of noise-reduction dust collector.
Background technology
Dust catcher of the prior art includes housing, the wind turbine being arranged in housing and the cover being located at outside wind turbine, The main function of dust catcher is the dust aspirated in ground or gap, by inside the air sucking dust catcher containing dirt using It is discharged after separation from exhaust outlet.Since the air draught of sucking generates sharp pounding in the channel being set to inside dust catcher, Very big noise can be generated, while the air-flow that the rotation of high speed electric fan is sucked also can generate strong vibrations and generate In, low frequency noise, seriously affected around environment, further affect the normal live and work of people.
Traditional dust catcher is by increasing air duct tortuosity, that is, mazy air duct so that sound wave is being propagated through Energy loss in journey and sound-absorbing porous material is disposed to absorb acoustic energy by air duct turning, so as to reach the mesh of noise reduction , still, the noise reduction that such structure is reached is undesirable, it is impossible to reach desired noise reduction;At present, it is existing Technology also has the air outlet setting silencing means in dust catcher to reach noise reduction purpose, but increases silencing means and cause dust suction The holistic cost of device increases, and is unfavorable for industrialized promotion and application.
Utility model content
The utility model to solve the above-mentioned problems, provides a kind of reasonable in design, easy to use and noise reduction It is good, the low noise-reduction dust collector of production cost.
The utility model adopts the following technical solution:
A kind of noise-reduction dust collector, including body of dust collector, the body of dust collector includes pedestal, is set on pedestal Dust bucket, motor and head cover, dirt bag and bung are equipped in the dust bucket, air filter is equipped in the dirt bag, it is described The center of bung is equipped with holding tank recessed down, and the bottom of holding tank is equipped with reserved opening, and the lower end of the motor is set to appearance Receive in slot, the bottom of motor is equipped with air inlet hole, be along the circumferential direction evenly distributed on the lower end outer wall of the motor several the One air outlet, it is described on the madial wall of the holding tank and corresponding to being equipped with outlet air noise reduction sponge at the position of the first air outlet Inner motor cover is equipped at the top of bung and positioned at the outside of motor upper end, the top of the inner motor cover is equipped with outsides cover of electric machinery, institute The top that head cover is set to outsides cover of electric machinery is stated, the head cover is equipped with exhausting plate, and the inner wall of exhausting plate is equipped with exhausting plate sponge.
As a kind of optimal technical scheme of the utility model, the inner motor cover is cirque structure, inner motor cover The ventilating duct of honeycomb is provided between inner circle and outer circle.
As a kind of optimal technical scheme of the utility model, the air filter is HEPA high efficiency particle air filters.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, and the access way of air is carried out using the structure of dust catcher in itself Level Four noise reduction process, wherein motor the sucked air that runs at high speed enter receiving by the first air outlet of motor bottom first Slot carries out level-one noise reduction by the outlet air noise reduction sponge on holding tank madial wall, and air flows into again to be led to by the honeycomb of inner motor cover Air duct carries out two level noise reduction, and the chamber that air is flowed into again between outsides cover of electric machinery and head cover later carries out three-level noise reduction, last air It is discharged in the exhausting plate of head cover, level Four noise reduction process is carried out with exhausting plate sponge and exhausting plate, using multistage noise reduction process Motor can be effectively reduced and noise caused by air-flow vibrations is driven in high-speed rotation, and extra noise reduction need not be increased Device, production cost is low, suitable for industrial production application.

Specific embodiment
The utility model row is further described presently in connection with attached drawing.
As shown in Figure 1, a kind of noise-reduction dust collector, including body of dust collector 1, the body of dust collector 1 includes pedestal 2nd, dust bucket 3, motor 4 and the head cover 5 being set on pedestal 2, the dust bucket 3 is interior to be equipped with dirt bag 6 and bung 7, the dirt bag 6 Interior to be equipped with air filter 8, the air filter 8 is HEPA high efficiency particle air filters, and the center of the bung 7 is equipped with downwards Recessed holding tank 9, the bottom of holding tank 9 are equipped with reserved opening, and the lower end of the motor 4 is set in holding tank 9, motor 4 Bottom is equipped with air inlet hole, and the position of the air inlet hole and the position of reserved opening are corresponding, in order to which motor 4 draws air into dust suction In device, several first air outlets 10, the holding tank 9 are along the circumferential direction evenly distributed on the lower end outer wall of the motor 4 Madial wall on and corresponding to outlet air noise reduction sponge 11 is equipped at the position of the first air outlet 10, on the bung 7 and positioned at electricity The outside of 4 upper end of machine is equipped with inner motor cover 12, and the inner motor cover 12 is cirque structure, the inner circle of inner motor cover 12 and outer The ventilating duct of honeycomb is provided between circle, the top of the inner motor cover 12 is equipped with outsides cover of electric machinery 13, and the head cover 5 is set to The top of outsides cover of electric machinery 13, the head cover 5 are equipped with exhausting plate 14, and the inner wall of exhausting plate 14 is equipped with the outlet air for level Four noise reduction Plate sponge 15.
The principle of the utility model is as follows:
When dust catcher works, motor 4, which runs at high speed, is sucked air by air inlet hole, then the first outlet air by 4 lower end of motor Mouth 10 is discharged into holding tank 9, carries out level-one noise reduction by the outlet air noise reduction sponge 11 on 9 madial wall of holding tank, air flows into electricity again The honeycomb ventilating duct of machine inner cover 12 carries out two level noise reduction, and air flows into the chamber between outsides cover of electric machinery 13 and head cover 5 again later Three-level noise reduction is carried out, last air is discharged in the exhausting plate 14 of head cover 5, the carry out four with exhausting plate sponge 15 and exhausting plate 14 Grade noise reduction process.
