Abstract
The utility model relates to a dust tube of a vacuum cleaner, which comprises an air flow inlet, an air flow outlet, a dust separating chamber, an outer tube and an inner tube, wherein the air flow inlet is arranged on the outer tube and is communicated with the dust separating chamber, the dust separating chamber is positioned between the outer tube and the inner tube, and the air flow outlet is positioned on the upper part of the inner tube. The lower part of the outer tube is pivoted with a bottom cover of the dust tube, and a sealing ring of the inner tube is arranged on the bottom cover of the dust tube. When the bottom cover of the dust tube is in a closed state, the bottom cover of the dust tube is hermetically connected with the outer tube, and the sealing ring of the inner tube is hermetically attached to the inner tube. The sealing performance between the inner tube and the bottom cover of the dust tube is good, which can prevent large dust and fine dust in the dust separating chamber from entering the inner tube.
Description
Technical field
The utility model relates to a kind of dirt tube of vacuum cleaner.
Background technology
In the prior art, the dirt tube of vacuum cleaner comprises urceolus, inner core, offer air flow inlet on the urceolus, the inner core upside is provided with air stream outlet, has the dust separation chamber between urceolus and the inner core, the air-flow that has dust tube inner chamber and in the indoor separation of carrying out dust of dust separation outside air flow inlet enters, thus it is indoor to make big ash and thin dirt stay dust separation, and air-flow enters inner core then.Being connected with in the bottom of urceolus can be with the dirt tube bottom of urceolus sealing, but owing to have the gap between inner core and the dirt tube bottom, so have circulation of air between the inner chamber of dust separation chamber and inner core, make dust easily enter in the inner core, thereby influence the operate as normal of vacuum cleaner.
Summary of the invention
The utility model purpose provides a kind of dirt tube of vacuum cleaner, and the sealing between its inner core and the dirt tube bottom is better.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dirt tube of vacuum cleaner, comprise air flow inlet, air stream outlet, dust separation chamber, urceolus, inner core, described air flow inlet is opened on urceolus and with the dust separation chamber and is connected, described dust separation chamber is between urceolus and inner core, and described air stream outlet is positioned at the top of inner core.The bottom of described urceolus is pivotally connected dirt tube bottom, when described dirt tube bottom is in closed condition, described dirt tube bottom is tightly connected mutually with urceolus, described dirt tube bottom is provided with the inner core sealing ring, when described dirt tube bottom was in closed condition, described inner core sealing ring sealed applying mutually with inner core.
Because technique scheme utilization, the utility model compared with prior art has following advantage: dirt tube bottom is provided with the inner core sealing ring, by being sealed and matched of inner core sealing ring and inner core, make that the sealing between inner core and the dirt tube bottom is better, can prevent that indoor big ash of dust separation and thin dirt from entering in the inner core.

The specific embodiment
Referring to accompanying drawing 7, a kind of dirt tube of vacuum cleaner, comprise air flow inlet 10, air stream outlet 13, dust separation chamber 11, urceolus 1, inner core 2, described air flow inlet 10 is opened on urceolus 1 and with dust separation chamber 11 and is connected, described dust separation chamber 11 is between urceolus 1 and inner core 2, and described air stream outlet 13 is positioned at the top of inner core 2.The air-flow that has dust is in air flow inlet 10 enters dust separation chamber 11, big ash collides and falls into the bottom of dust separation chamber 11 with the wall portion of urceolus 1 along with the rotation of air-flow, the upside of inner core 2 has cartridge filter 12, thin dirt passes through the filtration of filter cylinder 12 and is separated with clean gas flow, makes dust stay in the dust separation chamber 11.Air stream outlet 13 is positioned at the top of cartridge filter 12, and pure air is in air stream outlet 13 enters the negative pressure chamber of vacuum cleaner at last.
Referring to accompanying drawing 1-accompanying drawing 7, the bottom of described urceolus 1 is pivotally connected dirt tube bottom 5, when described dirt tube bottom 5 is in closed condition, described dirt tube bottom 5 is tightly connected mutually with urceolus 1, described dirt tube bottom 5 is provided with inner core sealing ring 4, when described dirt tube bottom 5 was in closed condition, described inner core sealing ring 4 sealed applying mutually with inner core 2.By being sealed and matched of inner core sealing ring 4 and inner core 2, make that the sealing between inner core 2 and the dirt tube bottom 5 is better, can prevent that the dusts in the dust separation chamber 11 from entering in the inner core 2 from the bottom of inner core 2.
Referring to accompanying drawing 2-accompanying drawing 6, the lower surface of described inner core 2 has inclined-plane 14, and the peripheral portion of described inner core sealing ring 4 has the sheet 9 of wiping, and when described dirt tube bottom 5 was in closed condition, described wiping sheet 9 fitted tightly mutually with inclined-plane 14.When dirt tube bottom 5 is opened, the wiping sheet 9 of inner core sealing ring 4 hold its shape (seeing accompanying drawing 2); In the process that dirt tube bottom 5 is closed gradually, wiping sheet 9 is subjected to the extruding on inclined-plane 14 and is out of shape, and wiping sheet 9 is wiped the thin dirt (seeing accompanying drawing 3, accompanying drawing 5) on the inclined-plane 14; When dirt tube bottom 5 is closed fully, wipe sheet 9 and just fit tightly mutually with inclined-plane 14, make that the sealing effectiveness between inner core 2 and the dirt tube bottom 5 is good, thus avoided big ash or too much carefully dirt enter in the inner core 2 and influence the operate as normal of vacuum cleaner.
