Abstract
The utility model relates to an air purification's technical field discloses amortization formula air cleaner, including being used for the air exit with the air escape who purifies the completion, air exit department is equipped with silencing device, silencing device has and to supply the air to pass through and cushion the ventilation cavity of amortization, silencing device one end is equipped with the intercommunication extremely the intake pipe of air exit, the other end are equipped with the outlet duct, be equipped with in the ventilation cavity be used for cushioning the amortization inhale the sound structure. The utility model provides an amortization formula air cleaner locates to have set up silencing device at the air exit, and the air gets into the inside ventilation cavity of silencing device after the air exit outflow, and the air is inhaled sound structure absorption noise behind ventilation cavity, reaches amortization denoising's effect, makes amortization formula air cleaner ability continued work under comparatively quiet environment.
Description
Technical field
The utility model relates to the technical field of purification of air, particularly relates to muffling type air cleaner.
Background technology
Air cleaner is a kind of common electronic equipment, and it has air inlet and air outlet, and air is cleaned discharge after flowing into air cleaner.Due to many reasons such as power of motor, dust accumulation, purification process, especially under fan high speed conditions, air cleaner has larger noise, go out to spread out of from air outlet, in use affect Consumer's Experience, if reduce power of motor and rotating speed, then purification efficiency can be caused to reduce.
Utility model content
The purpose of this utility model is to provide low muffling type air cleaner, is intended to solve the problem that in prior art, air cleaner noise is larger.
The utility model realizes like this, muffling type air cleaner, comprise the exhaust outlet that the air for having purified is discharged, described exhaust outlet place is provided with silencing means, described silencing means has and can pass through for air and cushion the vented cavity of noise reduction, described silencing means one end is provided with the air inlet pipe being communicated to described exhaust outlet, and the other end is provided with escape pipe, is provided with the sound-absorbing structure for cushioning noise reduction in described vented cavity.
Further, described sound-absorbing structure comprises and is arranged at described vented cavity inner and the first chamber opened by baffle for separating and the second chamber, and described dividing plate is provided with the pipeline for being communicated with the two.
Further, described air inlet pipe is communicated in described second chamber, and described escape pipe is communicated in described first chamber.
Further, described air inlet pipe, through described first chamber and described dividing plate, is communicated to described second chamber; Described escape pipe, through described second chamber and described dividing plate, is communicated to described first chamber.
Further, described sound-absorbing structure is made up of sound-absorbing material.
Compared with prior art, muffling type air cleaner in the utility model is provided with silencing means at exhaust outlet place, air enters the vented cavity of silencing means inside after exhaust outlet outflow, after vented cavity, air is by sound-absorbing structure, absorbing vibration, reach noise reduction except the effect of making an uproar, make muffling type purification of air function continuous firing under comparatively quiet environment.
Accompanying drawing explanation
The structural representation of the muffling type air cleaner that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the schematic diagram that the utility model embodiment air flow leads to direction;
The internal structure schematic diagram of the silencing means that Fig. 3 provides for the utility model embodiment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Be described in detail below in conjunction with the realization of concrete accompanying drawing to the present embodiment.
As shown in Figure 1, muffling type air cleaner, comprise fore shell 1, filter screen 2, back cover 6, air inlet 7, exhaust outlet 8, at exhaust outlet 8, place is provided with silencing means 9.Because silencing means 9 is arranged on the inside of back cover 6, its structure not shown in FIG, can understand whole purifying air and the quiet course of work according to Fig. 2.
As shown in Figure 3, silencing means 9 has the vented cavity that can pass for air.Air inlet pipe 91 is connected with in vented cavity one end, one end is connected with escape pipe 93, is also provided with sound-absorbing structure in vented cavity inside, after air flows out from exhaust outlet 8, enter in vented cavity from air inlet pipe 91, be buffered deceleration, a part of noise is absorbed by sound-absorbing structure simultaneously, after last air is discharged from silencing means 9, noise is largely eliminated, user is when use muffling type air cleaner, and noise jamming is obviously less, can enjoy quiet and have a home from home of pure air.
The concrete set-up mode of silencing means 9 can have multiple, such as the inner pipeline being set to multidirectional bending and arranging, and pipe interior passage forms vented cavity, duct wall forms sound-absorbing structure, air flows in the pipeline bent back and forth, shakes and is absorbed by tube wall, realizes quiet effect; Or multiple noise-damping bowl be arranged side by side is set between air inlet pipe 91 and escape pipe 93, in the middle part of each noise-damping bowl, offers through hole for air circulation, when air flows through, reached the effect of noise reduction by noise-damping bowl absorbing vibration; Can also honeycomb be set to, make air pass honeycomb with the state of dispersing, be absorbed vibrations and reach erasure effect etc.
Particularly, adopt the structure of sound-absorbing structure as shown in Figure 3 in the present embodiment, the vented cavity of silencing means 9 inside is separated into two chambers in left and right: be connected by pipeline between the first chamber 921 and the second chamber 922, two chambers.Air inlet pipe 91 and blast pipe 92 are communicated to two different chambers respectively, make air successively must flow through two chambers, are buffered noise reduction continuously and could flow out silencing means 9, reach the effect of noise reduction.
In order to improve erasure effect further, air inlet pipe 91 in the present embodiment is through first chamber 921 and the dividing plate on the left side, stretch into second chamber 922 on the right, escape pipe 93 is through second chamber 922 and the dividing plate on the right, stretch into first chamber 921 on the left side, after air enters from air inlet pipe 91, first the second chamber 922, absorption noise is buffered in this chamber, then the first chamber 921 is entered by pipeline, by the air stroke originally directly flowed out, change to tortuous back and forth outflow, further buffering noise reduction, when finally leaving from escape pipe 93, complete noise reduction, there is less noise.
Sound-absorbing structure can also be other structures be made up of sound-absorbing material, such as, be sticked by sound-absorbing sponge inner at vented cavity, or enclose the modes such as stereochemical structure, by the characteristic absorption noise of material self.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
