Abstract

The utility model discloses a dust collector, which comprises a dust collector body, wherein a dust collecting pipe is arranged on the lower portion of the body. The dust collector is characterized in that the dust collecting pipe is composed of a metal inner pipe in a spiral corrugated folded shape capable of bending and a plastic outer pipe, the outer pipe is fixedly wrapped on the inner pipe through limitation, the dust collecting pipe can be arbitrarily bended, thereby the dust collecting direction of the dust collector can be arbitrarily changed to collect dust on any angle, the places on the original corners or turning parts and the like, which can not be cleaned easily can be easily cleaned, and the product has simple structure, convenient use and low cost.

Description

Dust catcher

Technical field

The utility model relates to the dust catcher technical field, and especially a kind of sweep-up pipe is the dust catcher of bending arbitrarily.

Background technology

The sweep-up pipe length of existing dust catcher is mainly all decided by sweep-up pipe, sweep-up pipe generally all is a linear pattern, flexible vertically, can not be crooked, can not change direction, therefore be to be difficult to be drawn onto dust carrying out the cleaning of corner or turning, new dust catcher such as the patent No. 200610039035.1 universal vacuum cleaner telescopic tubes have also appearred at present, its telescoping tube comprise at least two the joint mutual sleeve telescopic in, outer tube, in described, retaining mechanism is housed between the outer tube, an end that it is characterized in that described interior pipe has the spherical hinge structure, telescoping tube can be regulated angle required between two pipes by the spherical hinge structure, and the direction that so just can change telescoping tube is carried out all angles dust suction.The flexible pipe structure of this dust catcher is complicated, bending arbitrarily, and cost is higher.

Summary of the invention

The purpose of this utility model is to provide a kind of dust catcher, and especially a kind of sweep-up pipe of dust catcher can be crooked arbitrarily, can change the dust suction direction of dust catcher arbitrarily, and simple and practical.

Technical solution adopted in the utility model is: a kind of dust catcher, comprise body of dust collector, one sweep-up pipe is arranged at the bottom of body, it is characterized in that: the sweep-up pipe of described dust catcher is made up of the metal inner pipe and a plastic cement outer tube socket of the helical corrugation rugosity of an energy bending.

As improvement, described sweep-up pipe outer tube wall is provided with and the corresponding spiral type spacing groove of the projection of the helical corrugation rugosity of interior pipe, and can be by spacing fixing back hard-pressed bale on inner pipe between the interior pipe.

Because the interior pipe of sweep-up pipe is a spiral rugosity structure, just can be crooked arbitrarily as required; Outer tube is an Elastic plastic-rubber pipe, and hard-pressed bale plays the effect of managing and being convenient to hold in the protection on inner pipe.

The utility model has the advantages that: the sweep-up pipe of this kind dust catcher is bending arbitrarily, dust catcher just can carry out the dust suction of all angles like this, and originally the place that is difficult to clear up such as corner or turning can both solve easily, and product structure is simple, easy to use, cost is low.

Fig. 2 is a sweep-up pipe exploded view of the present utility model;

Fig. 3 is a sweep-up pipe internal anatomy of the present utility model.

The specific embodiment

Anticipate as Figure 1-3, a kind of hand held cleaner, comprise body of dust collector 10, body 10 is mainly become by motor, blower fan, sweep-up pipe 1, bag dust filter, shell, handle and other enclosure group, after dust catcher is connected power supply, draught fan impeller is under the driving of motor, rotation at a high speed drives blade air is constantly done work, and the air in the dust catcher is constantly discharged, make its inner instantaneous vacuum, i.e. quite high Negative Pressure Difference of formation between dust catcher inside and the ambient atmosphere of forming.Under the effect of this Negative Pressure Difference, near the garbage dust the suction nozzle enters bag dust filter again and filters along with air-flow process sweep-up pipe 1.Garbage dust is stayed in the bag dust filter, and the clean air after the filtration is discharged from air outlet through exhaust chamber.

Owing to the sweep-up pipe 1 of dust catcher of the present utility model by one can bending the metal inner pipe 2 of helical corrugation rugosity and a plastic cement outer tube 3 sockets form; metal inner pipe 2 gets up by the joint socket; form helical corrugation projection 2.1; plastic cement outer tube 3 inwalls are provided with the helical corrugation rugosity projection 2.1 corresponding spiral limited impressions 3.1 with metal inner pipe 2; pass through spacing fixedly hard-pressed bale in interior pipe 2 outsides with interior pipe 2, play the effect of managing and being convenient to hold in the protection.Sweep-up pipe 1 bending arbitrarily so as long as pull out just bending arbitrarily as required of sweep-up pipe 1 when using, change direction and carry out dust suction, uses and then resets sweep-up pipe 1 usefulness hand just passable.

Claims

1. a dust catcher comprises body of dust collector, and a sweep-up pipe is arranged at the bottom of body, it is characterized in that: described dust catcher sweep-up pipe be by one can bending the metal inner pipe and a plastic cement outer tube of helical corrugation rugosity be socketed to form.

2. dust catcher according to claim 1 is characterized in that: the inwall of the sweep-up pipe outer tube of described dust catcher is provided with the corresponding spiral limited impression of helical corrugation rugosity projection with interior pipe, by spacing fixedly hard-pressed bale on inner pipe.

3. dust catcher according to claim 1 is characterized in that: described metal inner pipe is by the joint socket.
