Description
Technical Field
The invention relates to the field of dust collectors, in particular to a dust filtering bag of a double-bag type dust collector.
Background
The working principle of the dust collector is that a motor of the dust collector rotates at a high speed, air is sucked from a suction inlet, a dust box generates certain vacuum, dust enters a dust filtering bag in the dust box through a floor brush, a connecting pipe, a handle, a hose and a main suction pipe, the dust is left in the dust filtering bag, filtered air enters the motor through a layer of filter disc, and the air entering the motor flows out through the motor and is discharged from an air outlet.
By filter bag is meant a bag-like filter device which usually has an air inlet from which an air stream entrained with dust is introduced, which air stream flows out of the filter bag from its periphery, while the dust is retained in the filter bag. In the prior art, filter bags are made of various materials according to different filtering requirements, such as single-material filter paper or filter cloth, and also composite material filter bags. The existing filter bags are all the same in air permeability, and for larger dust collectors, such as the bucket type dust collector shown in the US patent 5548868, because of the larger space, the larger filter bag can be used, and the problem of serious dust blockage can not be caused. However, for a vacuum cleaner with a small volume, the volume of the collecting barrel of the vacuum cleaner is small, and only a small filter bag can be used, particularly for a filter bag with a short and long shape, when larger particles of dust and sundries are filtered, the filter bag is easy to block around the suction opening.
The filter bag of dust catcher mainly is used for collecting and filtering the dust that the dust catcher inhales, and tiny dust can be detained on the material surface of filter bag, along with detaining the increase of dust volume, the windage of filter bag material also rises, reaches the certain degree after, and filter bag just can not be used, and at present, there is the defect in the following aspect in the filter bag: 1. when the garbage is accumulated in the dust filter bag to a certain degree, the air exhaust effect is greatly reduced, the suction force is greatly reduced due to partial blockage, and the dust removal effect is seriously reduced; 2. the existing dust filter bag is directly connected with a motor, and when the motor operates, the dust filter bag is adsorbed on the motor, so that the suction effect is influenced; 3. the overall dimension of dust catcher filter bag can not unlimited expansion, and the overall dimension all holds the chamber according to the dust catcher and designs mainly, holds the chamber in order to prevent that the filter bag is damaged or blasting when using, and the filter bag size all is just pasting on holding the chamber wall, utilizes holding the chamber wall to support the filter bag, and suction is too big when preventing to use, causes filter bag damage or blasting. The filter bag is larger than the containing cavity, and the filter material is folded and accumulated. The accumulation of air is difficult to pass through, which increases the pressure loss of the filter bag. It is not possible to increase the filtering area to the outside of the filter bag.
CN201580026544.8 discloses a cleaner filter bag for an upright cleaner, which has a length greater than the width, resulting in one long side and one narrow side. The vacuum cleaner filter bag is formed from two bag walls which are joined together circumferentially such that an interior space is formed between the two bag walls. One bag wall has an inlet opening, through which the air to be cleaned can enter the vacuum cleaner filter bag. The vacuum cleaner filter bag according to the invention is characterized in that the bag wall in which the inlet is introduced has a fold extending in the longitudinal direction of the vacuum cleaner filter bag, whereby the bag wall has an increased elasticity and, when the filter bag is inserted into the vacuum cleaner, the vacuum cleaner filter bag unfolds when the support plate is folded, so that air can enter the filter bag substantially unimpeded.
Patent No. CN201280024590.0 includes a vacuum cleaning apparatus of a vacuum cleaner and a filter bag, the inventive filter bag being formed as a disposable, flat non-woven filter bag having a first filter bag wall and a second filter bag wall, the filter bag having at least one surface fold, wherein each surface fold comprises an area in the surface area of the filter bag wall and an area protruding above the surface area of the filter bag wall and being expandable during vacuum cleaning, the vacuum cleaner comprising a filter bag receiving space having a rigid wall.
In the two inventions, the dust filter bag has a complex structure, and the vacuum cleaner is arranged in the dust filter bag and can only be used in a specific dust collector.
In conclusion, the problem of low utilization efficiency of the filter bag is urgently solved by the inventor in the field.
