The present invention discloses a cyclone noise suppressor of dust collector and dust cup device containing said device. It includes an air exhaust tube which is partially inserted into the cyclone barrel interior, the outer wall of said air exhaust tube is equipped with a downwards guided screw surface, ad the lower edge of said air exhaust tube is downwards extended and is equipped with a lattice ring, and said lattice ring is formed into a conical body which is downwards progressively reduced, the rib in the lattice ring and the lower end face of air exhaust tube are formed into an included angle, and said included angle is less than or equal to 90deg. Said device can effectively reduce noise of air exhaust tube.
Description
Technical field
The present invention relates to a kind of Whirlwind silencing of dust catcher and comprise the cup device for dust of this device.
Background technology
In traditional dust catcher filter is installed, purpose is that the dirty air that will suck filters, therefore dust granule is stayed in the dust collect plant,, this type of dust catcher is after using a period of time, the user should clear up filter or change, otherwise, after the filter opening of filter is stopped up by thin dust, can increase the resistance of vacuum motor, severe patient even can burn out motor has not only brought trouble to the user, and can influence the performance and the life-span of dust catcher.
In recent years, manufacturer substitutes filter according to the principle of cyclonic separation with cyclone dust collector, has obtained dust removing effects preferably, therefore is widely applied on the dust catcher.As shown in Figure 1, this cyclone dust collector is provided with a conical cyclone tube in the dirt cup, the upper end of whirlwind tube vertically is provided with a discharge pipe, and be communicated with the air outlet of dirt cup, the lower end of whirlwind tube is provided with opening, so that dust falls into the disposal box of dirt cup bottom, blast pipe also tangentially enters in whirlwind tube upper portion side wall, make the air-flow that has dust in the whirlwind tube, produce whirlwind, dust granule drops to the dust-collecting box bottom at action of centrifugal force lower edge whirlwind tube sidewall, and the air-flow after the dedusting is upwards discharged the dirt cup through discharge pipe.
But, in actual applications, find that also this cyclone exists the place of some shortcomings: the one, discharge pipe can send high frequency noise when work; The 2nd, because the height of whirlwind air inlet and discharge pipe is suitable, the air that enters from the whirlwind air inlet hits the side at discharge pipe, when not being rotated down the arrival conical shell as yet, can producing collision with the air that the whirlwind air inlet newly enters, thereby can produce noise.
Summary of the invention
The objective of the invention is: a kind of Whirlwind silencing of dust catcher is provided and comprises the cup device for dust of this device, this device has grid in the design of the lower edge of discharge pipe, lateral layout at discharge pipe has the backspin helicoid simultaneously, avoids the collision of air intake, thereby reduces the generation of noise.
Technical scheme of the present invention is: a kind of Whirlwind silencing of dust catcher, comprise that part is inserted into the discharge pipe in the whirlwind tube, the outer wall of discharge pipe is provided with the helicoid of downward guiding, the lower edge of described discharge pipe is extended with the grid circle downwards, the grid circle is downward diminishing bullet, the rib in the grid circle and the lower surface of discharge pipe are an angle, and angle is smaller or equal to 90 degree, and the rib in the grid circle is arc shaped.
A kind of cup device for dust of dust catcher comprises:
One whirlwind tube is in order to the dust of centrifugation air;
One dust hopper, it is arranged on the below of whirlwind tube, in order to collect the dust that is separated; And
One discharge pipe, it is arranged on the top of whirlwind tube and the inside that part is inserted into the whirlwind tube, and the lower edge of described discharge pipe is extended with the grid circle downwards.
Advantage of the present invention is:
1. the present invention has the grid of downward extension in the design of the lower edge of discharge pipe, to reduce noise.
2. the present invention also has the helicoid of downward guiding in the lateral layout of discharge pipe, makes the air that enters from the whirlwind air inlet form whirlwind soon and flows downward, and avoids bumping with the air that entered afterwards, has played the effect that reduces noise equally.
Description of drawings
The invention will be further described below in conjunction with embodiment:
Fig. 1 is the structural representation of existing cyclone dust collector;
Fig. 2 is an assembling schematic diagram of the present invention;
Fig. 3 is the stereogram of discharge pipe of the present invention;
Fig. 4 is user mode figure of the present invention.
Wherein: 1 whirlwind tube; 2 discharge pipes; 3 grid circles; 4 ribs; 5 helicoids; 6 whirlwind air inlets; 7 blast pipes; 8 bowl covers; 9 air inlets; 10 netted filtering tubes; 11 cups; 12 dust fall annular spaces; 13 dust hoppers; 14 air outlets.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of Whirlwind silencing of dust catcher, comprise that part is inserted into the discharge pipe 2 in the whirlwind tube 1, the outer wall of discharge pipe 2 is provided with the helicoid 5 of downward guiding, the lower edge of discharge pipe 2 is extended with grid circle 3 downwards, and grid circle 3 is downward diminishing bullet, and the rib 4 in the grid circle 3 is an angle with the lower surface of discharge pipe 2, angle is smaller or equal to 90 degree, and the rib 4 in the grid circle 3 is arc shaped.
A kind of cup device for dust of dust catcher comprises:
One whirlwind tube 1 is in order to the dust of centrifugation air;
One dust hopper 13, it is arranged on the below of whirlwind tube 1, in order to collect the dust that is separated; And
One discharge pipe 2, it is arranged on the top of whirlwind tube 1 and the inside that part is inserted into whirlwind tube 1, and the lower edge of described discharge pipe 2 is extended with grid circle 3 downwards.
During use, sweep-up pipe is connected on the blast pipe 7, dirty air enters respectively the air inlet 9 of two bowl covers 8 from blast pipe 7, removes cinder dirt through netted filtering tube 10, and cinder dirt is fallen the bottom of cup 11, thin dust and air enter into whirlwind tube 1 by whirlwind air inlet 6, and the formation whirlwind, in the whirlwind process, thin dust falls along the inwall of backspin air duct 1, enter dust hopper 13 bottoms by dust fall annular space 12, remove the air of dust and then upwards discharge through air outlet 14 from discharge pipe 2.
The present invention has the grid 3 of downward extension in the design of the lower edge of discharge pipe 2, to reduce noise; The present invention also has the helicoid 5 of downward guiding in the lateral layout of discharge pipe 2, make the air that enters from whirlwind air inlet 6 form whirlwind soon and flow downward, and avoids bumping with the air that entered afterwards, has played the effect that reduces noise equally.
