Description
Technical field
The present invention relates to a kind of fore filter for dust catcher, relate in particular to a kind of motor prefilter that relies on self vibration to realize cleaning.
Background technology
Usually, dust catcher comprises power section, filtration system, functional part, safeguard measure part and five basic function parts of annex.Power section is made of motor of dust collector-fan component, speed regulator.Filtration and vacuum part are made of dirt bag, front filter and after-filter.Filtering material is minute papery, cloth matter, sponge net, SMC (the soft sheet molding compound that Sheet Molding Compound is comprised of multiple materials such as fiber, resin, curing agent, thickener, low shrinkage additive, fillers) and HEPA (efficiency particulate air High efficiency particulate air again, filter efficiency for the micronic dust more than 0.3 micron can up to 99.97%, be a kind of good air purification filter material).Functional part mainly comprises retractable cable mechanism, dust-full indication, button or slide switch etc.The safeguard measure part mainly comprises free-bag protection, the too high protection of vacuum, anti-interference protection (soft start), overtemperature protection, antistatic protection.Annex generally includes handle and flexible pipe, adapter, scrubbing brush, flat suction nozzle, circle brush, sofa suction nozzle, hook and braces etc.
The dedusting of dust catcher energy, " head " that mainly be it is equipped with motor-fan component, in the rotating shaft of blower fan, fan blade arranged, after energising, the High Rotation Speed of blower fan produces extremely strong suction and pressure, under the effect of suction and pressure, air is discharged at a high speed, and the air of blower fan front end vacuum part constantly replenishes the air in blower fan, cause the instantaneous vacuum of the inner generation of dust catcher, form Negative Pressure Difference with external atmosphere pressure, under the effect of this pressure reduction, suck the air that contains dust.Dust and other impurities enters bag dust filter by carpet or floor cleaner brush or suction nozzle, long pipe, bend pipe, flexible pipe, hose coupling successively, and dust and other impurities is trapped in bag dust filter, and air is discharged by the body afterbody after filter purifies later.
In air in motor-fan component, foreign body filtering will fall in order to flow into, in order to avoid affect the normal operation of motor, be provided with fore filter in motor the place ahead.Motor prefilter can adopt gross porosity to filter sponge, and its voidage is up to 97%, has excellent gas permeability, good flexibility and higher mechanical strength, and not only flow resistance is little, and it is high to leach rate.Dust catcher uses a period of time or at the dust of assembling in fore filter more than specified amount, just needs to replace or the cleaning motor prefilter.In prior art, automatically cleaning mode for fore filter is mainly that the filtration sponge that will disassemble utilizes external force to pat, remove wherein dust with bat, vibrations effect for hard materials such as filter paper the time is apparent in view, but concerning sponge material, external force can be fallen by spongy absorbing mostly, and the vibrations cleaning effect is not obvious; It is to use to dry after cold water cleans that a kind of mode is arranged again again, and attempting the sponge cleaning, its process comparatively bothers, and can not steep with hot water wash when cleaning, can not dry, otherwise, can cause the sponge distortion and the space is stopped up, affect filter effect.The automatically cleaning mode of above-mentioned two kinds of fore filters is all comparatively difficult for client.
Summary of the invention
For above-mentioned prior art, the invention provides a kind of motor prefilter with self vibration cleaning, mesh by profile of tooth and directly will filter the sponge shell and be connected on filter stand, make the external shock of the vibrations replacement transmission of filter stand, the absorption that can effectively avoid sponge to shake to external world reaches the cleaning to the sponge filtering material, improves the suction maintenance, extend the cycle that client cleans fore filter, make things convenient for customers.
In order to solve the problems of the technologies described above, the technical scheme that a kind of motor prefilter with self vibration cleaning of the present invention is achieved is: comprise the base that is arranged on motor housing internal filter installation portion, the filtration sponge frame that coordinates with described motor housing, described filtration sponge frame is provided with and filters sponge, described filtration sponge has been set up centre bore, be fixed with rotating shaft in described centre bore, one end of described rotating shaft is provided with rotating handles, and the other end of described rotating shaft is provided with the first end face helical gear; Described rotating shaft is provided with the shaft shoulder, in described rotating shaft, is being provided with compression spring between the described shaft shoulder and described filtration sponge frame; Be fixed with the second end face helical gear with described the first end face helical gear engagement on described base.
The present invention has the motor prefilter of self vibration cleaning, and wherein, described the first end face helical gear and described the second helical gear profile of tooth of end face are to press the zigzag of annular spread on end face.Described the first end face helical gear and the helical gear whole depth of the second end face are all less than the axial deflection of described compression spring.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention has the motor prefilter of self vibration cleaning, what adopt is a kind of structure that can make the whole vibrations of filtering material, by top rotating handles rotation, make the integrally vibrations vertically of whole fore filter, thereby the dust on it is fallen, reach the purpose that improves the suction maintenance.
