Abstract

The utility model relates to a whirlwind cylinder body of a suction cleaner, which comprises a cylinder body that is provided with an air inlet, a flow guiding pipe that is arranged in the cylinder body, and a dust separation chamber which is formed between the flow guiding pipe and the cylinder body, wherein the flow guiding pipe comprises an entering air mesh cover, and meshes are arranged on the entering air mesh cover. An airflow channel is arranged in the flow guiding pipe, and the dust separation chamber is communicated with the airflow channel through the meshes. An included angle alpha is formed between the extrusion direction of the meshes and the axial lead of the entering air mesh cover and is larger than 0 DEG and smaller than 90 DEG. When the airflow enters the meshes, the direction of the airflow is changed suddenly. The dust in the airflow and the air have differences on density and quality and differences on centrifugal force and inertia, so the modicum dust in the airflow can be separated.

Description

The cyclone separating tube of dust catcher

Technical field

The utility model relates to a kind of cyclone separating tube of dust catcher.

Background technology

In the prior art, the cyclone separating tube of dust catcher comprises the mozzle in cylindrical shell and the cylindrical shell, constitute the dust separation chamber between mozzle and the cylindrical shell, mozzle comprises the body on top, the Inlet Network escutcheon at middle part and the interior dirt tube of bottom, the air inlet of air-flow on cylindrical shell that has dust enters the dust separation chamber, dust separation is indoor carry out dust separation after, the mesh of air on the Inlet Network escutcheon enters in the inner chamber of mozzle.And common perforate direction of mesh and radially paralleling of Inlet Network escutcheon, so when the air-flow that contains small amount of dust enters in the mesh, still keep original direction of motion, make the air-flow band in the inner chamber that small amount of dust directly enters mozzle, cause the effect of this cyclone separating tube dust-separating relatively poor.

Summary of the invention

The utility model purpose provides a kind of cyclone separating tube of dust catcher, and it enters small amount of dust in the air-flow of gas channel through can be separated behind the mesh from the dust separation chamber.

For achieving the above object, the technical solution adopted in the utility model is: a kind of cyclone separating tube of dust catcher, comprise the cylindrical shell with air inlet, the coaxial mozzle that is arranged in the described cylindrical shell, constitute the dust separation chamber between described mozzle and the described cylindrical shell, the top of this dust separation chamber has the top cover that is arranged between cylindrical shell and the mozzle, the bottom of this dust separation chamber has the bottom that is arranged between cylindrical shell and the mozzle, and this dust separation chamber is connected with described air inlet.Described mozzle comprises mozzle body, the interior dirt tube of bottom, the Inlet Network escutcheon between described mozzle body and interior dirt tube on top, have a plurality of mesh on the described Inlet Network escutcheon, have gas channel in the inner chamber of described mozzle, described dust separation chamber also is connected with gas channel by mesh.Has angle α between the axial line of the bearing of trend of described mesh and Inlet Network escutcheon, 0 degree＜α＜90 degree.

Because technique scheme utilization, the utility model compared with prior art has following advantage: the radial skew of the relative Inlet Network escutcheon of the bearing of trend of mesh, make air-flow break-in suddenly in the process that enters gas channel from mesh, because dust and air in the air-flow exist density and qualitative difference, make the centrifugal force and the inertia of dust and air have difference, the dust separation effect of this cyclone separating tube has been improved in the bottom of assembling and fall into the Inlet Network escutcheon under centrifugal force and action of inertia so the small amount of dust in the air-flow can be separated.

The specific embodiment

Referring to accompanying drawing 1-accompanying drawing 2, a kind of cyclone separating tube of dust catcher, comprise the cylindrical shell 1 with air inlet 5, the coaxial mozzle 11 that is arranged in the described cylindrical shell 1, constitute dust separation chamber 13 between described mozzle 11 and the described cylindrical shell 1, the top of this dust separation chamber 13 has the top cover 16 that is arranged between cylindrical shell 1 and the mozzle 11, the bottom of this dust separation chamber 13 has the bottom 9 that is arranged between cylindrical shell 1 and the mozzle 11, and this dust separation chamber 13 is connected with described air inlet 5.Described mozzle 11 comprises mozzle body 3, the interior dirt tube 15 of bottom, the Inlet Network escutcheon 4 between described mozzle body 3 and interior dirt tube 15 on top, in the embodiment shown in the accompanying drawing 1-accompanying drawing 2, mozzle body 3, interior dirt tube 15, the 4 trisome settings of Inlet Network escutcheon, be convenient to the product assembling, and interior dirt tube 15 radially diminishes with respect to Inlet Network escutcheon 4, and it is separated and stay the bottom of dust separation chamber 13 to help dust.Have a plurality of mesh 8 on the described Inlet Network escutcheon 4, have gas channel 10 in the inner chamber of described mozzle 11, described dust separation chamber 13 also is connected with gas channel 10 by mesh 8.

Dusty gas is in air inlet 5 enters dust separation chamber 13, and move downward at dust separation chamber 13 inside spins, most of dust in the gas is close to the inwall of cylindrical shell 1 under action of centrifugal force, and be split on the bottom 9 under the drive at spiral air flow after when arriving the inner wall surface of cylindrical shell 1, assembling, there is the fraction dust then to enter in the gas channel 10 from mesh 8 in addition with air-flow.

Has angle α between the axial line of the bearing of trend of described mesh 8 and Inlet Network escutcheon 4,0 degree＜α＜90 degree, the i.e. radial skews of the relative Inlet Network escutcheon 4 of perforate direction of mesh 8.Referring to the embodiment shown in the accompanying drawing 3, the perforate direction of described mesh 8 is downward-sloping to inwall from the outer wall of Inlet Network escutcheon 4; Referring to the embodiment shown in the accompanying drawing 4, the perforate direction of described mesh 8 is inclined upwardly from outer wall to the inwall of Inlet Network escutcheon 4.Enter in the process of mesh 8 at air-flow, because the radial skew of mesh 8 relative Inlet Network escutcheons 4, make air-flow have unexpected break-in, and there are density and qualitative difference between dust in the air-flow and the air, the difference that has caused the centrifugal force and the inertia of dust and air, so the dust in the air-flow can be under centrifugal force and action of inertia is separated with air and falls into the inner bottom part of Inlet Network escutcheon 4, reach the effect of further purifying gas flow, improved the dust separation effect of this cyclone separating tube.
