Abstract

The dust collector includes dust collecting unit with motor, and dust barrel with barrel body and filter on frame. The dust collecting unit is provided with detection switch and the dust barrel with triggering mechanism. When the filter frame is mounted onto the barrel body, the triggering mechanism is matched to the detection switch to make the motor in start enable state; and when the filter frame is separated from the barrel body, the triggering mechanism is matched to the detection switch to make the motor in start disable state. The motor may be started only when the filter frame is mounted onto the barrel body, and this ensure the safety of the motor and the dust collector.

Description

Dust catcher

Technical field

The present invention relates to a kind of dust catcher.

Background technology

In the prior art, the filter of dust catcher, needs often to change or cleaning and filtrating equipment for guaranteeing pick-up performance because of the sticking grey vulnerable to pollution of dust suction.But the user easily forgets after changing filter clean filter is reapposed in the dust catcher, dust in the start cleaning dust kicked up by somebody walking in front tube promptly is drawn in the motor of dust collector, thereby cause the motor blocking, be heated and make the motor stall, even cause motor overheating, burning and the initiation potential accident.

Summary of the invention

The object of the invention provides a kind of dust catcher, and its motor can't be opened when filter is not correctly installed.

Technical scheme of the present invention is: a kind of dust catcher, comprise body of dust collector with motor, be arranged at the dirt tube on the described body of dust collector, described dirt tube comprises dirt tube body, is removable installed in the filter holder with filter on the described dirt tube body.Described body of dust collector is provided with sense switch, and described sense switch is used to control motor and is in starting state or the No starting state of allowing.Described dirt tube is provided with trigger mechanism, this trigger mechanism has two operating positions at least, when the filtration support is contained on the dirt tube body, described trigger mechanism is in first operating position, and described trigger mechanism cooperates with sense switch and makes motor be in the permission starting state under this first operating position; When filtering support and break away from dirt tube body, when described trigger mechanism was in second operating position, described trigger mechanism cooperated with sense switch and makes motor be in the No starting state under this second operating position.

The present invention compared with prior art, have following advantage: body of dust collector is provided with sense switch, the dirt tube is provided with trigger mechanism, by cooperating of trigger mechanism and sense switch, make when the filtration support is installed on the dirt tube body, motor can be activated, and has guaranteed the trouble free service of motor and dust catcher with this.

The specific embodiment

Referring to accompanying drawing 1-accompanying drawing 2, a kind of dust catcher, comprise body of dust collector 17 with motor, be arranged at the dirt tube 18 on the described body of dust collector 17, described dirt tube 18 comprises dirt tube body 2, is removable installed in the filter holder with filter 7 on the described dirt tube body 2.Described body of dust collector 17 is provided with sense switch 6, and described sense switch 6 is used to control motor and is in starting state or the No starting state of allowing, and for example with the moving microswitch of sense switch 6 choosings, the power supply of it and motor is in series.Described dirt tube 18 is provided with trigger mechanism 16, this trigger mechanism 16 has two operating positions at least, when filtration support 7 is contained on the dirt tube body 2, described trigger mechanism 16 is in first operating position, and described trigger mechanism 16 cooperates with sense switch 6 and makes motor be in the permission starting state under this first operating position; When filtering support 7 and break away from dirt tube bodies 2, when described trigger mechanism 16 was in second operating position, described trigger mechanism 16 cooperated with sense switch 6 and makes motor be in the No starting state under this second operating position.

Referring to accompanying drawing 3-accompanying drawing 5, described trigger mechanism 16 comprises frizzen 5, is provided with frizzen stage clip 10 between described frizzen 5 and the dirt tube body 2, and the afterbody of described frizzen 5 is provided with handles knob 19, described 19 outsides of exposing at dirt tube body 2 of handling knob.When described trigger mechanism 16 was in first operating position, described frizzen 5 was against on the sense switch 6, and when described trigger mechanism 16 was in second operating position, described frizzen 5 broke away from described sense switch 6.Described trigger mechanism 16 also comprises the frizzen baffle plate 9 that is provided with versatilely with respect to dirt tube body 2, when described trigger mechanism 16 is in first operating position, described frizzen baffle plate 9 discharges frizzen 5, described frizzen 5 is against on the sense switch 6, when described trigger mechanism 16 is in second operating position, described frizzen baffle plate 9 locking frizzens 5, described frizzen 5 breaks away from described sense switch 6.

Be provided with baffle plate stage clip 11 between described dirt tube body 2 and the described frizzen baffle plate 9, has filter holder inclined-plane 8 on the described filter holder 7, when described filter holder inclined-plane 8 is against on the lower surface of described frizzen baffle plate 9, move the described frizzen 5 of release on the described frizzen baffle plate 9, described trigger mechanism 16 is in first operating position; When described filter holder inclined-plane 8 broke away from the lower surface of frizzen baffle plates 9, described trigger mechanism 16 was in second operating position, and described frizzen baffle plate 9 moves down and locks frizzen 5.

Have perforation 20 on the described frizzen baffle plate 9, when described trigger mechanism 16 was in first operating position, described frizzen 5 passed this perforation 20.The upside hole wall portion of described perforation 20 is provided with stop part 12, the side portion of described frizzen 5 has shoulder 15, when described trigger mechanism 16 is in first operating position, described stop part 12 discharges shoulder 15, described shoulder 15 passes perforation 20, when described trigger mechanism 16 was in second operating position, described stop part 12 was inconsistent with shoulder 15, and the head of described frizzen 5 passes described perforation 20.

Referring to accompanying drawing 3, during dismounting dirt tube 18, pinch handle knob 19 and on carry dirt tube carrying handle 3, make dirt tube 18 break away from body of dust collector 17, pinch in 19 the process of handling knob that frizzen 5 overcomes the active force of frizzen stage clip 10 and motion backwards, make the shoulder 15 of frizzen 5 break away from perforation 20, frizzen baffle plate 9 promptly is subjected to the active force of baffle plate stage clip 11 and moves downward, and makes stop part 12 and shoulder 15 offset, thereby makes trigger mechanism 16 be in second operating position.Referring to accompanying drawing 5, after filter holder 7 dismounting and reinstalling, again dirt tube 18 is installed in the process of body of dust collector 17, by cooperating of filter holder inclined-plane 8 and frizzen baffle plate 9 bottom surfaces, make frizzen baffle plate 9 overcome baffle plate stage clip 11 active force and on move, the stop part 12 of frizzen baffle plate 9 promptly discharges shoulder 15, make the shoulder 15 of frizzen 5 to pass 20 from boring a hole, at this moment, if dirt tube 18 is installed on the body of dust collector 17, then but the head detection trigger switch 6 of frizzen 5 makes motor be in and allows starting state (referring to accompanying drawing 1); And if the correct installation of filter holder 7 is about to dirt tube 18 and is installed on the body of dust collector 17, frizzen 5 breaks away from sense switches 6, makes motor be in No starting state (referring to accompanying drawing 2).

By cooperating of frizzen 5 and frizzen baffle plate 9 and sense switch 6, the duty of motor with the control dust catcher, motor can start when making filter holder 7 correct installations, can prevent that the dust in the dirt tube 18 from entering in the motor, thereby can guarantee the security of motor and even dust catcher operation.
