Abstract
The present invention discloses a vacuum cleaner with an automatic dust removing device, which comprises a vacuum cleaner housing, a suction force generating part, a filtering part, a dust collecting part, a separating baffle, an exhaust outlet, suction inlets, an air flow path and a foreign substance collecting box. The present invention is characterized in that an opening and closing valve for sucking reverse circulating air in is arranged on the vacuum cleaner housing. The suction force generating part sucks air in which foreign substances are contained through a first suction inlet or sucks reverse circulating air through a second suction inlet. The air flow path is connected with a flow path converting valve assembly. The foreign substance collecting box which is used for placing the vacuum cleaner in enables the first suction inlet and the second suction inlet to be communicated and combined with each other and collects foreign substances in the reverse circulating air. The vacuum cleaner of the present invention can maintain the cleanness of the filtering part all the time after used, and a dust storage space can be designed into a smaller one to reduce the volume of the vacuum cleaner; thus, a user does not need to clean a filter personally. The present invention is safe and sanitary.
Description
Technical field
The present invention relates to vacuum cleaner, especially after dust suction finishes, with the dust of disposal box inside to the inner vacuum cleaner of collecting automatically of foreign matter collecting box.
Background technology
Generally speaking, vacuum cleaner is to utilize inhalation power to remove the machine of foreign matters such as dust.As shown in Figure 1, the vacuum cleaner structure of prior art is: separate with separating dividing plates 101 shell 100 of vacuum cleaner is inner, a side is for sucking the dust collecting part of dust, and opposite side provides the inhalation power generating unit of inhalation power during for control of dust.
Dust collecting part is by the suction line 111 that sucks the air that contains foreign matter from the outside, inlay the suction inlet 112 that is communicated with suction line 111, the filter element 113 that separates the air that comprises foreign matter that sucks by suction inlet 112 constitutes with the disposal box 114 that is positioned at filter element 113 downsides.For air being delivered to the inhalation power generating unit, with the air flow circuit 115 that the inboard of filter element 113 is communicated with, the hang plate 114a that the upside of disposal box 114 has the dust that prevents control of dust to flow down downwards or the dust of bottom disperses.
The inhalation power generating unit is the inlet hole 102 that is sucked by air flow circuit 115 by the air that perforation separation dividing plate 101 will separate in filter element 113, be incorporated into the fan electromotor 120 that separates dividing plate 101 by inlet hole 102 sealings, be positioned at a sidewall of shell 100, the tap 103 of discharging fan electromotor 120 inhaled airs constitutes.
The air that comprises foreign matter that the vacuum cleaner of above-mentioned structure sucks by suction inlet 112, parts 113 filter after filtration, remaining dust will flow into disposal box 114 along hang plate 114a, the air that is filtered is through the inlet hole 102 of air flow circuit 115, separation dividing plate 101, by fan electromotor 120, discharge to tap 103.Even vacuum cleaner is dedusting not, inhalation power can not reduce, but when being equipped with the screen pack dedusting on air flow circuit, along with lasting control of dust, impedance is increased, and inhalation power reduces.If under the control of dust state, work on, increase the probability that the room pollutes, and increase the volume of dust catcher.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of at vacuum cleaner, control of dust can be collected automatically the automatic dust removing apparatus of dust catcher outside in the foreign matter of disposal box, prevent the stream impedance that in filter element, takes place and the pollution again of house interior, and needn't often open dust catcher in order to sweep the dust in the disposal box.
In order to address the above problem, the technical solution used in the present invention is: a kind of vacuum cleaner that possesses automatic dust removing apparatus, constitute by dust catcher and foreign matter collecting box, dust catcher comprises Body case of cleaner, inhalation power generating unit, filter element, dust collecting part, separation dividing plate, tap, first suction inlet, second suction inlet, air flow circuit, and the open and close valve that sucks contrary circulating air is set on Body case of cleaner; The inhalation power generating unit sucks from first suction inlet and sucks the air that comprises foreign matter or pass through the contrary circulating air of second suction inlet suction; Air flow circuit is connected with the cross valve door assembly; The foreign matter collecting box is used to place dust catcher, makes first suction inlet and second suction inlet be interconnected combination, collection against the airborne foreign matter that circulates.
The cross valve door assembly comprises the stream vario valve of controlling air flow circuit and moves up and down the rod member of stream vario valve.By separating air flow circuit sidewall that dividing plate and dust collecting part sidewall constitute the protuberance that stops of a pair of displacement that limits the stream vario valve is being arranged.
The foreign matter collecting box comprises the vertical portion that has the dedusting suction inlet, is interconnected and combines with first suction inlet; The base of placing dust catcher, being interconnected and combining with second suction inlet with dedusting outlet; Be placed on the dust removal and filtration net of the side that the vertical portion is communicated with base.
Open and close valve by rotary in conjunction with hinge, be incorporated into second suction inlet, one side and open and close the switching sheet material of second suction inlet and elastomeric element that the elasticity support opens and closes sheet material constitutes.
Side at the dedusting outlet of foreign matter collecting box forms open protuberance.
The invention has the beneficial effects as follows: it is clean to keep filter element all the time after vacuum cleaner uses, the problems such as strange taste that do not exist inhalation power corruption low and pollutant to cause, and can design the dust storage space less, reduce the dust catcher volume, the user needn't clear up filter, safety and sanitation in person.
