Abstract

The invention provides a dust collecting tube of a dust collector. The dust collecting tube comprises a hose, wherein, a soft bag is arranged around the outside of the hose; the hose and the soft bag are jointly connected with an air inlet joint at a port; the hose is communicated with an air inlet tube of the dust collector through the air inlet joint; the soft bag is communicated with an inflation hose through the air inlet joint; and the inflation hose is connected to an exhaust port of the dust collector through a tee joint. When in use, the rigidity of the tube can be flexibly adjusted according to the need of operating positions, thus meeting the operating requirements for various operating positions.

Description

The dust catcher sweep-up pipe

Affiliated technical field

The present invention relates to a kind of domestic vacuum cleaners, especially, relate to the sweep-up pipe of dust catcher.

Background technology

Dust catcher is a kind of common household electrical appliance, because it can absorb the dust on surfaces such as floor, carpet, sofa easily, therefore is widely loved by the people; Its cardinal principle is to produce negative pressure through air pump in dust catcher inside, thereby makes sweep-up pipe that outside dusty gas is sucked dust catcher inside, and behind the dust catcher self-filtering, clean gas is then discharged from blast pipe.

And in the use of dust catcher; Because the continuous variation of operating position; Sometimes need adopt flexible pipe to carry out dust suction, need make sweep-up pipe be rigidity sometimes again, therefore in use need frequent dismounting or change sweep-up pipe as sweep-up pipe; To satisfy the demand of various different operatings position, this makes indoor sweeping very bother; And more common dust catcher, its sweep-up pipe or even can not change adjusting, therefore for the operation of different operating position, comparatively inconvenience.

Summary of the invention

To the problems referred to above, the object of the present invention is to provide a kind of dust catcher sweep-up pipe, this sweep-up pipe in use can be according to the needs of operating position, its rigidity of flexible, thus satisfy the operation of various operating positions easily.

The technical solution adopted for the present invention to solve the technical problems is: this dust catcher sweep-up pipe comprises a flexible pipe; This flexible pipe outside also surrounds a soft bag; Said flexible pipe is connected an inlet suction port jointly with soft bag in the port; This inlet suction port is conducted the air inlet pipe of said flexible pipe and dust catcher, and said soft bag is conducted with an inflated hose, and said inflated hose is connected to the exhaust outlet of dust catcher through a threeway.

As preferably, said flexible pipe is a plastic film capicitor, in BENDING PROCESS, can keep its caliber everywhere constant.

As preferably, in the said threeway, two straight-through interfaces connect said inflated hose and dust collector exhaust mouth respectively.

As preferably, said soft bag is made up of the rubber skin, its bottom through ultrasonic sealing weldering welding in said hose surface.

Beneficial effect of the present invention is: this dust catcher sweep-up pipe if need not to use the rigidity sweep-up pipe, then only needs said threeway is broken away from the dust collector exhaust mouth in use, no pressed gas in the then said soft bag, and sweep-up pipe relies on the flexible dust suction of said flexible pipe; If when needing to use rigid pipe, then said threeway is placed on the dust collector exhaust mouth, then in the exhaust process of dust catcher, said soft bag is inflated, under gas pressure, and exceptionally straight expanding very, then whole sweep-up pipe is rigidity; This sweep-up pipe in use can be according to the needs of operating position, its rigidity of flexible, thus satisfy the operation of various operating positions easily.

Fig. 2 is this dust catcher sweep-up pipe and the sketch map that is connected of dust catcher.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

In Fig. 1, embodiment shown in Figure 2, this dust catcher sweep-up pipe comprises a flexible pipe 11, and these flexible pipe 11 outsides also surround a soft bag 12; This soft bag 12 is made up of the rubber skin; On said flexible pipe 11 surfaces, its port then extends to said flexible pipe port through ultrasonic sealing weldering welding in its bottom, and; Said flexible pipe 11 and soft bag 12 are connected an inlet suction port 2 jointly in the port; This inlet suction port 2 is conducted the air inlet pipe 5 of said flexible pipe 11 with dust catcher 4, and this inlet suction port 2 has a cavity that surrounds said air inlet pipe 11, and this cavity side connects a charging connector 21; Said soft bag 12 is conducted through this charging connector 21 and an inflated hose 3, and said inflated hose 3 is connected to the exhaust outlet 6 of dust catcher 4 through a threeway 7.

Above-mentioned dust catcher air intake duct, said flexible pipe 11 is a plastic film capicitor, in BENDING PROCESS, can keep its caliber everywhere constant.

Above-mentioned dust catcher air intake duct; In the said threeway 7; Two straight-through interfaces connect said inflated hose 3 and dust collector exhaust mouth 6 respectively; Interface 71 wherein so more helps dust catcher 4 when exhaust then as the new exhaust outlet of dust catcher 4, and said soft bag 12 is formed bigger inner gas pressure.

Above-mentioned dust catcher sweep-up pipe if need not to use rigidity sweep-up pipe 1, then only needs said threeway 7 is broken away from dust collector exhaust mouth 6 in use, no pressed gas in the then said soft bag 12, and sweep-up pipe 1 relies on said flexible pipe 11 flexible dust suctions; If when needing to use rigid pipe, then said threeway 7 is placed on the dust collector exhaust mouth 6, then in the exhaust process of dust catcher, said soft bag 12 is inflated, under gas pressure, and exceptionally straight expanding very, then whole sweep-up pipe 1 is rigidity; This sweep-up pipe in use can be according to the needs of operating position, its rigidity of flexible, thus satisfy the operation of various operating positions easily.
