Abstract

The utility model discloses a multifunctional blowing and sucking type suction cleaner, which is provided with an air blowing device 18. A dust suction pipe 8 is sheathed on an inner blowing dust pipe 11. The air blowing opening 14 of the air blowing device 18 is connected with the inner dust blowing pipe 11 through a vessel so as to make strong airflow be discharged from the dust blowing nozzle 17 in a dust suction head 10 and dust and sundries are flied up by the strong airflow. The dust and the sundries are sucked in a dust collection chamber 12 from a channel arranged between a dust suction pipe 8 and the inner blowing dust pipe 11 by negative pressure. Air filtered by a filtering net 5 enters an air blowing chamber to form an air circulation loop. The multifunctional blowing and sucking type suction cleaner is suitable for various occasions, and has the advantage of high suction clearness. Besides, the utility model has no secondary dust pollution. After the dust collection chamber 12 is dismounted, the multifunctional blowing and sucking type suction cleaner can be used as an air blowing device.

Description

Multifunctional blowing and sucking type suction cleaner

The utility model relates to a kind of multi-functional blowing-sucking type vacuum cleaner with air circulation loop, belongs to cleaner.

At present, the dust catcher instrument of sweeping health as family and public place is extensive use of by people.But existing dust catcher mostly only with powerful suction as cleaning means, function singleness can not exhaust dirt depending merely on the occasion that the high wind inhalation power can't clean.Especially pick-up performance is relatively poor on scraggly object, causes the exhaustion degree of dust catcher low, and can produce secondary dust pollution phenomenon.

The purpose of this utility model provides a kind of air circulation loop that has, and dependence is blown, inspiratory flow reaches dust suction purpose multifunctional dust vacuum cleaner, thereby improves the exhaustion degree, and is applicable to the dust suction of different occasions such as scraggly object.

The purpose of this utility model is achieved in that increases a blowing device in dust catcher, an interior dust blowing tube is installed in the sweep-up pipe, and termination of dust blowing tube is to the drifting dust air-flow in this, and the other end is positioned at suction nozzle inside.There is the space to lead to the dust pocket between interior dust blowing tube and the sweep-up pipe and constitutes the dust suction path.Blow out a malleation air-flow from the blowing mouth of dust catcher, lead to interior dust blowing tube, deliver to the dust inlet place of suction head of suction cleaner through drifting dust tube connector and conduit.This normal pressure air-flow blows afloat dust, foreign material earlier, and then suck in the dust pocket by negative pressure by the cleaner head of dust catcher, thereby enter the closed cycle that blowing chamber forms air through filtered air, make the dust can be not excessive, avoid causing the secondary dust pollution, only overcome with the defective of strong suction as the dust suction means.The dust pocket can pull down from dust catcher, and the dust pocket is removed the blowing formation blowing device that partly has a style of one's own above the back.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the overall structure figure of the utility model dust catcher;

Fig. 2 is that dust catcher blows, the structure chart of cleaner head;

Fig. 3 is the structure chart of blowing device.

The label of each parts is respectively among Fig. 1: handle 1, and casing 2, motor 3, fan 4, screen pack 5, conduit 6, drifting dust tube connector 7, sweep-up pipe 8, castor 9 blows, cleaner head 10, interior dust blowing tube 11, dust pocket 12, blowing chamber 13, blowing mouth 14, dust pocket's air inlet 15.

Air blast in the blowing chamber 13 blows out by drifting dust tube connector 7 through blowing mouth 14, drifting dust tube connector 7 is connected with dust pocket's air inlet 15, air-flow is sent into the interior dust blowing tube 11 that is connected with dust pocket 12 through conduit 6 again, air blast through interior dust blowing tube 11 blowing, drifting dust mouth 17 in the cleaner head 10 blows out, dust, foreign material are blown afloat, by negative pressure dust, foreign material are sucked dust pocket 12 from the passage between sweep-up pipe 8 and the interior dust blowing tube 11 again, the air after filtering through filter screen 5 enters blowing chamber 13 and forms air circulation loop.

In the blowing of Fig. 2, the cleaner head 10, the drifting dust mouth 17 of interior dust blowing tube 11 is positioned at and blows, the inside of cleaner head 10, and the object that make drifting dust mouth 17 and blow, cleaner head 10 is contacted forms the space, dust, foreign material are blown afloat and are limited in blow, the inside of cleaner head 10.

Fig. 3 pulls up drifting dust tube connector 7 from dust pocket's air inlet 15, lay down the blowing device 18 that dust pocket 12 constitutes, and changes different blowing mouth 16, can be used for different occasions.

Dust catcher of the present utility model has the characteristics such as simple in structure, that cost is low, function is many. It is obvious to compare the exhaustion degree through its effects of test of multiple different occasions and dust catcher in the past Improve. Such as very obvious to the assimilation effect of the dust of the electronic component of printed circuit board (PCB) and superficial deposit dust, foreign material etc., be applicable to multiple different occasion.
