Description

A kind of vacuum cleaner with automatic dust removing apparatus

Technical field:

The utility model relates to a kind of dust catcher, especially a kind of vacuum cleaner with automatic dust removing apparatus.

Background technology:

Vacuum cleaner of the prior art, comprise suction motor, dust bucket and screen pack, the main effect of screen pack is to stop that being inhaled into the interior dust of dust bucket takes dust bucket out of with the air-flow that the suction motor produces, the space of having cleaned is polluted once more, because special job specification and the environment of screen pack, itself be easy to be stopped up, at this time just must clean screen pack by dust; The method of cleaning and filtering net in the past removes screen pack exactly, blow with high wind then, can blow the most dusts that stop up screen pack off like this, recover the function of screen pack, but, this cleaning method is too loaded down with trivial details and slowly, because we must remove screen pack earlier, installs after cleaned again.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of cleaning to have the vacuum cleaner of automatic dust removing apparatus easily and efficiently.

A kind of vacuum cleaner that provides according to the utility model with automatic dust removing apparatus, comprise staving, place the dust exhaust apparatus and the top cover of staving upper end, dust exhaust apparatus comprises supporting plate, be installed in the suction motor of supporting plate upper surface and be installed in the screen pack of supporting plate lower surface, the supporting plate mid portion has the airflow hole of a connection suction motor and screen pack, the supporting plate upper surface also is provided with the air flow circuit that is divided into by partition, the suction motor is communicated with extraneous by this air flow circuit, have an air outlet on the air flow circuit diapire, have an air-out passage on the supporting plate, this air-out passage one end communicates with air outlet, the other end communicates with screen pack inside, and described air outlet place also is provided with a stream conversion valve assembly.

The utility model also has following attached technical characterictic:

Described cross valve door assembly comprises the valve of salable described air outlet and the control device of by-pass valve control folding, valve is hinged on air outlet one side, on the valve its hinged place one end also extension one cantilever is arranged, control device comprises a control lever that is installed on the top cover moving up and down, this control lever one end and cantilever are replaced, the other end exposes to top cover, and a back-moving spring also is installed between control lever and top cover.

A kind of vacuum cleaner with automatic dust removing apparatus according to the utility model provides has following advantage with respect to prior art:

In this structure, pass through an air-out channel connection between air flow circuit and the screen pack, the porch of air-out passage is provided with valve and controls the cross valve door assembly of this valve, after screen pack stops up, push control lever in the cross valve door assembly with hand, air-out passage moment opens, gas flow in the screen pack through the air-out passage rapidly in the air flow circuit, screen pack is cleaned, once by cleaning, convenient, fast gently to screen pack.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of the utility model master apparent direction;

Fig. 2 is the sectional structure schematic diagram of I-I among Fig. 1;

Fig. 3 is the structure for amplifying schematic diagram of M among Fig. 1.

The specific embodiment:

With reference to Fig. 1, Fig. 2, Fig. 3, according to a kind of vacuum cleaner described in the utility model with automatic dust removing apparatus, comprise the staving 1 that is used for the splendid attire dust, place the dust exhaust apparatus 2 and the top cover 3 of staving 1 upper end, dust exhaust apparatus 2 comprises supporting plate 21, be installed in the suction motor 22 of supporting plate 21 upper surfaces and be installed in the screen pack 23 of supporting plate 21 lower surfaces, supporting plate 21 mid portions have the airflow hole 24 of a connection suction motor 22 and screen pack 23, supporting plate 21 upper surfaces also are provided with by cutting off 4 air flow circuits that are divided into 25, the air-flow of 22 sucking-offs of suction motor is rejected to the external world through this air flow circuit 25, have an air outlet 251 on air flow circuit 25 diapires, have an air-out passage 211 on the supporting plate 21, these air-out passage 211 1 ends communicate with air outlet 251, the other end communicates with screen pack 23 inside, air outlet 251 places also are provided with a stream conversion valve assembly 6, folding by these cross valve door assembly 6 control air outlets 251, when air outlet 251 is opened, air-flow flow in the screen pack 23 through air outlet 251 and air-out passage 211 rapidly in the air flow circuit 25, and the dust that is adsorbed on the screen pack 23 is blown off.

Cross valve door assembly 6 comprises the valve 61 of salable air outlet 251 and the control device 62 of by-pass valve control folding, valve 61 is hinged on air outlet 251 1 sides by bearing pin, on the valve 61 its hinged place one end also extension one cantilever 611 is arranged, control device 62 comprises a control lever 621 that is installed on the top cover 3 moving up and down, these control lever 621 1 ends and cantilever 611 are replaced, the other end exposes to top cover 3, one back-moving spring 9 also is installed between control lever 621 and top cover 3, press lower control arm 621, back-moving spring 9 is compressed accumulation of energy, simultaneously, cantilever 611 rotates cantilever 611 backspins with valve 61 around bearing pin under the effect of control lever 621, valve 61 perks, air outlet 251 is opened, and air stream flow in the screen pack 23 through air outlet 251 and air-out passage 211 rapidly, unclamps control lever 621, back-moving spring 9 resets rapidly, force and move on the control lever 621 and unclamp the replacing of cantilever 611, valve 61 also resets rapidly under the pressure of air stream, with air outlet 251 sealings.
