Abstract

The utility model provides a dust vacuum cleaner with automatic dust-excluding function comprising a suction blower which can become an air mover driven by the positively or negatively rotating motor, an electrical control gear, a gas distributor, a cracker pipe, and various parts or accessories of the original dust vacuum cleaner. When the electrical motor rotates negatively, the suction blower becomes an air mover to carry through blowing back and exhaust the dust on the parts of the dust filter and in the fine pores and dust storing chambers through the dust sucting pipes and cracker pipes. The cracker pipe can be inserted into the water and the dust can be cleaned by using the bubbling method. The utility model is characterized in that the dust exhaust and dust clean can be done in time; he efficiency of dust suction can be enhanced; the pollution and power consumption can both be driven down. In the dedusting situation of a large area, the dust vacuum cleaner of a smaller size can be chozen.

Description

Dust catcher with automatic dust-excluding function

Technical field under the utility model is a dust catcher.

At present the dust catcher that uses is made up of a base plate of using by motor-operated induced-draught fan, by the dress induced-draught fan, muffler, electrical control gear, dust component, appearance dirt chamber, shell, dust sucting pipeline, various dust suction annexes etc.The shortcoming of this kind dust catcher is that the work that reaches the indoor dust of appearance dirt of removing after the dust suction on the dust component is pretty troublesome, and forms the pollution to the user, so before the dust suction process is finished, the work of removing dust in the middle of generally not carrying out.In the dust suction later stage and since dust on dust component bulk deposition and the obstruction in the inner pore, the shortcoming that cause the resistance of dust component to increase, dust collection efficiency descends, power consumption increases.For the dust catcher that is used for the large tracts of land dust suction, can only solve with the method that increases a lot of dust chamber volume, increasing motor power, the appearance and size of dust catcher is strengthened, increased the inconvenience of using, reduced people to using the interest of dust catcher.

The purpose of this utility model provides the dust catcher of the automatic dust discharge of a kind of energy, when the dust discharge duty, it can be with dust in the inner pore, that appearance dirt is indoor patches an end of dust suction annex along dust sucting pipeline and insertion dust sucting pipeline the bubbling pipe discharge that reaches on the dust component.Bubbling pipe is inserted in the liquid (normally water), carry out the dedusting of wet method bubble cleaning.

But being achieved in that the dust catcher of automatically dust discharge, the purpose of this utility model can become the induced-draught fan of air blast when being counter-rotating of motor drives by a forward and backward, by adorning the base plate that induced-draught fan is used, muffler, dust component holds the dirt chamber, shell, dust sucting pipeline, the change-over switch that can control the motor forward and backward, a gas distributor, one is used for the bubbling pipe that the dedusting of wet method bubble cleaning is used, compositions such as various dust suction annexes and electrical control gear.When motor is just changeing, enter the dust suction duty.When motor reversed, induced-draught fan became air blast, carried out blowback, and the dust in the inner pore, that appearance dirt is indoor that reaches on the dust component is discharged along dust sucting pipeline and bubbling pipe.The air of blower export (induced-draught fan import) concentrates certain part of blowing at dust component to reduce drifting dust effect when preventing blowback, a gas distributor is set between blower export and dust component, its area should be greater than the area of induced-draught fan import, so just make air can blow to the each several part of dust component more equably, the simplest a kind of shape of gas distributor is an one flat plate.Bubbling pipe is a tubular member, and the tapering of profile of an end that the tapering of the profile of one end and dust suction annex insert dust sucting pipeline is identical, and the shape of the other end becomes the shape that makes the ash-laden gas physical efficiency that bloated and liquid that more contact-making surface be arranged.

Characteristics of the present utility model are automatically dust discharges, and with the dedusting of wet method bubble cleaning, reduce when removing dust on the dust component and that appearance dirt is indoor the pollution to the user.In addition, because blowback, a part of dust that also will lodge in the interior pore of dust component blows out, and has reduced resistance, improves dust collection efficiency next time, reduces power consumption.In addition, because blowback dust discharge easily, so, also can select dust catcher for use than small dimension for the occasion of large tracts of land dust suction.

Embodiment 1 of the present utility model, as shown in Figure 1 and Figure 2, wherein Fig. 1 is the dust collector structure sketch, but the electric control circuit schematic diagram of the dust catcher of the automatic dust discharge of energy that the induced-draught fan that Fig. 2 is a kind of single-phase series commutator motor of usefulness forward and backward to be driven constitutes.

Among Fig. 1, but 1 is the single-phase series excitation phase changer motor of forward and backward, 2 the time can become the induced-draught fan of air blast for counter-rotating, 3 are induced-draught fan inlet (blower export when being the air blast duty), 4 is gas distributor, 5 is dust component, 6 for holding the dirt chamber, 7 is dust sucting pipeline, 8 is bubbling pipe, and 9 are power switch and alignment circuit sub-assembly (not speed governing person does not have this circuit), 10 change-over switches for control motor forward and backward, the connection of electric wiring is only illustrated among the figure, and concrete elementary diagram is seen Fig. 2.

Among Fig. 2,11 is the stator winding of single-phase series commutator motor, and 12 is the rotor winding, and all the other are identical to those shown in Fig. 1.

Claims

1, the dust catcher of the automatic dust discharge of a kind of energy, be by motor-operated induced-draught fan by one, by adorning the base plate that induced-draught fan is used, muffler, electrical control gear, dust component, hold the dirt chamber, shell, dust sucting pipeline, compositions such as various dust suction annexes, it is characterized in that, the motor that adopts in the utility model be one can be just, the motor of counter-rotating, induced-draught fan can become the induced-draught fan of air blast when being a counter-rotating, increase by one in the electrical control gear and just can control motor, the change-over switch of counter-rotating, a gas distributor is set between blower export and dust component, also has one and be used for the bubbling pipe that the dedusting of wet method bubble cleaning is used.

2, dust catcher according to claim 1 is characterized in that the area of gas distributor should be greater than the area of induced-draught fan import.

3, dust catcher according to claim 1 is characterized in that bubbling pipe is a tubular member, and the tapering of the profile of one end is identical with the tapering of the profile of an end of dust suction annex insertion dust sucting pipeline.
