Abstract

The internal circulation type dust collector is mainly characterized by that in the suction head, hard connecting pipe, connecting plug-in component, soft connecting pipe and machine body portion two air channels of air suction and air blowing are set, and formed into internal circulation type air channel, and the shell body of the machine body is equipped with pressure-regulating valve. When the dust collector is used, sucked gas or dust circulates in the inner gas path, so that dust smaller than 5 microns is not discharged out of the machine body, and the health of a human body is facilitated.

Description

Internal circulating type suction cleaner

The utility model belongs to tame electric vacuum cleaner technical field, is the improvement to existing dust catcher.

Existing domestic vacuum cleaners are generally vacuum suction, are promptly rotated at a high speed by the driven by motor impeller, form negative pressuren zone and produce suction in body.Above-mentioned dust catcher all is that the gas that sucks is discharged outside the body after filtering.Yet present filter only requires and filters in the thorax staying greater than the dust more than 5 microns, and to not requiring less than the dust below 5 microns, thereby still is discharged into outside the body after in use installing after filtration less than 5 microns dust.Confirm according to occupational medicine,, can enter the lung deep by people's breathing less than 5 microns dust, bigger to people's harm.Though, but still exist and to suck less than outside 5 microns the dust discharge body so existing domestic vacuum cleaners have better dust suction.

The purpose of this utility model is to overcome existing will the suction less than the dust below 5 microns of above-mentioned dust catcher and discharges the body exterior problem, is that a kind of gas and dust with suction carries out the circulation of interior road, does not discharge a kind of internal-circulation type dust catcher of dust basically.

Design concept of the present utility model is all to have air-breathing and two gas circuits of blowing in suction nozzle, hard connecting leg, connection plug-in unit, soft connecting leg, body, and on the body housing pressure regulator valve is housed.

Below in conjunction with accompanying drawing structure of the present utility model is illustrated:

Fig. 1 is the general illustration of dust catcher;

Fig. 2 is a dust catcher body part schematic diagram;

Fig. 3, Fig. 4 are that dust catcher connects plug-in unit part schematic diagram;

Fig. 5 is a suction head of suction cleaner part schematic diagram;

Fig. 6 is a dust catcher pressure regulator valve schematic diagram.

Among Fig. 1,1 is that suction nozzle, 2 is body for connecting hard connecting leg, 3 for connecting plug-in unit, the hard connecting leg 2 of connection and soft connecting

leg

4,5, and free body handle 12 and pressure regulator valve 14 are arranged on body;

Among Fig. 2, the front end gas port is two pores, the road 6 of promptly blowing, air-breathing road 7, in body, constitute the ring gas circuit by shell body 11 and dividing plate 13 and empty body handle, promptly form hole, air-breathing road, by filter bag chamber 8, impeller cavity 9, motor cavity 10, constitute air-breathing road 7, constitute air blowing road 6 by back casing, empty body handle 12, upper end procapsid and internal partition 13 by lower house and dividing plate 13;

Connecting plug-in unit 3 among Fig. 3,4 is made up of socket and plug, socket is enclosed within outside the hard connecting leg 2 by outer tube 15, in the crack spring 16 is housed between outer tube 15 and the hard connecting leg 2, hard connecting leg front end adhering and sealing pad 17, a fore shaft 18 is respectively arranged on the outer tube two sides, plug is enclosed within soft connecting leg 4 front ends by sleeve pipe 19, and a plastics shell fragment 20 is respectively arranged on the sleeve pipe two sides;

Among Fig. 5, suction nozzle 1 constitutes air blowing road 6 by upper shell and central dividing plate 21, chews 22 at dividing plate front end and the air blowing of housing front end formation, and dividing plate 21 constitutes air-breathing road 7 with lower house;

Among Fig. 6, pressure regulator valve 14 is made of with the valve rod 28 that is contained in spring 26, the valve block 27 in the valve seat and be screwedly mounted on the valve block pore on the body housing 23 and the valve seat 24 that is fixed in the housing, and steam vent 25 is arranged on the valve seat 24; Hard connecting leg 2 constitutes air blowing road 6 and air-breathing road 7 with soft connecting leg 4 by body and internal partition.

The utility model has been owing to adopted suction nozzle with two gas circuits, hard connecting leg, connected plug-in unit, soft connecting leg, make body form in the circulation gas circuit, when dust catcher is worked, suction is just circulated in interior gas circuit less than 5 microns dust, can not go out external.Thereby help the health of human body.
