Abstract
The utility model discloses a dust collector, which comprises a ventilating pipe. An air inlet and an air outlet which are used for being connected with a dust absorbing tube are respectively disposed at two ends of the ventilating pipe, a dust collecting cavity is arranged on the lateral wall of one side of the ventilating pipe in a communicated manner, and a filter screen is disposed inside the ventilating pipe. The dust absorbing tube is connected between a dust absorbing head and a vacuum cleaner body when the dust collector is used, granular sundries are blocked by the filter screen at the inlet of the ventilating pipe to fall into the dust collecting cavity when driven to flow through the ventilating pipe by wind force, separation of the granular sundries and tiny dust is realized, accordingly collision among the granular sundries and impellers of a fan is avoided, the service lives of the impellers of the fan are prolonged, and the dust collector is simple in structure and convenient in installation and utilization and can also be used with other vacuum cleaners.
Description
Technical field
The utility model relates to a kind of dust arrester of being used with dust catcher of being used for.
Background technology
The patent No. is that the Chinese patent open file of ZL03256730.8 discloses a kind of automobile-used dust catcher, this dust catcher comprises shell, blower fan, sweep-up pipe and dust-exhausting port, be provided with vacuum chamber in the shell, the impeller of blower fan is arranged in the vacuum chamber, and vacuum chamber is respectively equipped with sweep-up pipe interface and dust-exhausting port.This dust catcher adopts the straight-line design, utilizes the suction of blower fan with sweep-up pipe the dust in the car cabin directly to be discharged outside the car from dust-exhausting port.This dust catcher directly is communicated with vacuum chamber owing to sweep-up pipe, it is when having dropped the graininess foreign material in the car, this graininess foreign material can directly enter into vacuum chamber by sweep-up pipe, produces high velocity impact with the draught fan impeller that is provided with in the vacuum chamber, the damage impeller causes dust catcher to damage easily.
The utility model content
The purpose of this utility model is: a kind of dust arrester is provided, and this dust arrester and dust catcher are used and can solve the problem that existing dust catcher damages easily.
The technical solution of the utility model is: a kind of dust arrester, comprise ventilation duct, and the two ends of ventilation duct are respectively equipped with air inlet and the air outlet that is used to connect sweep-up pipe, are communicated with to be provided with dust-collecting cavity on a side sidewall of ventilation duct, are provided with filter screen in ventilation duct.
The front end inlet of described dust-collecting cavity is near the air inlet of ventilation duct, is provided with in dust-collecting cavity over against described air inlet, towards the face that keeps out the wind of dust-collecting cavity rear end bending.
The rear end of described dust-collecting cavity is connected ventilation duct near on the outer wall of air outlet, and the middle part of described ventilation duct makes ventilation duct and dust-collecting cavity enclose the middle part and has the hollow ring structure of passing for finger to away from the bending of dust-collecting cavity direction.
Described filter screen is arranged at ventilation duct near on the front end inner tubal wall of dust-collecting cavity.
The utility model is connected between cleaner head and the main body of dust collector by sweep-up pipe in use, when being driven by ventilation duct by wind-force, the graininess foreign material stopped by the filter screen of ventilation duct porch, drop in dust-collecting cavity, realize separating of graininess foreign material and small dust, thereby can prevent to produce collision between graininess foreign material and the draught fan impeller, prolong the service life of draught fan impeller, it is simple in structure, easy to install, also can with the supporting use of other dust catcher.
Description of drawings
Fig. 1 is the structural representation of the utility model dust arrester specific embodiment.
Arrow is depicted as the air-flow trend among the figure.
The specific embodiment
The specific embodiment of dust arrester of the present utility model as shown in Figure 1, it comprises a ventilation duct 11, the two ends of ventilation duct 11 are respectively equipped with air inlet 12 and the air outlet 13 that is used to connect sweep-up pipe, be provided with a dust-collecting cavity 15 at ventilation duct 11 near being communicated with on the bottom tube wall of air inlet 12, the front end inlet of this dust-collecting cavity 15 is near the air inlet 12 of ventilation duct 11, and the inner tubal wall of ventilation duct 11 is provided with the filter screen 16 that is used to stop the graininess foreign material.In the present embodiment, in order to improve the separating effect of graininess foreign material and dust, dust-collecting cavity 15 inwalls be provided with air inlet 12 over against being provided with and towards the face that keeps out the wind 17 of dust-collecting cavity 15 rear end bendings, simultaneously, filter screen 16 is arranged in the ventilation duct 11 near dust-collecting cavity 15 front end inlet places.Be the ease for use that increases this dust arrester and attractive in appearance, in the present embodiment, the rear end of dust-collecting cavity 15 is connected ventilation duct 11 near on the outer wall of air outlet 13, the middle part 14 of ventilation duct 11 is to the direction bending away from dust-collecting cavity 15, make ventilation duct 11 and dust-collecting cavity 15 enclose the middle part and have the hollow ring structure of passing, thereby make the middle part 14 of ventilation duct 11 form the handle structure that grips for staff for finger.
