Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filtering device for a barrel-type vacuum cleaner. Background Art

[0002] The filter device of a barrel vacuum cleaner has the characteristics of large capacity, water absorption, and dust removal. A barrel vacuum cleaner filter device currently available includes a head, a dust bag assembly, and a barrel body. One end of the dust bag assembly is removably mounted within the barrel body, and the other end of the dust bag assembly is provided with a support ring, which is located at the top of the barrel body. The head is removably mounted on the inner wall of the support ring, and the outer diameter of the head is smaller than the inner diameter of the barrel body. When packaging or storing the filter device of the barrel vacuum cleaner, the head can be completely installed within the barrel body because the outer diameter of the head is smaller than the inner diameter of the barrel body. At the same time, the dust bag assembly is installed within the barrel body, thereby greatly reducing the space occupied by the barrel filter, which helps save transportation costs and storage space. However, the direct attachment of the dust bag to the support ring means that when the dust bag is replaced, the support ring must also be discarded. Since the support ring needs to be used in conjunction with the dust bag, barrel body, and head, discarding the entire set would result in a significant waste.

[0003] In order to solve the above-mentioned defects, the prior art has a method of circumferentially clamping one end of the dust bag ring at the support position between the support ring and the top of the barrel body or circumferentially clamping the dust bag ring at the support position between the support ring and the machine head, and the other end of the dust bag ring is fixedly connected to the open end of the dust bag. Although this method can achieve the purpose of separating the dust bag and the support ring to reduce waste; however, the dust bag ring is set on the support ring or the top of the barrel body, and finally the dust bag ring is clamped by the support ring or the machine head and the barrel body. Although the dust bag ring and the dust bag can be taken out from the barrel body or the support ring separately to avoid the waste of discarding the whole set, the dust bag and the dust bag ring must be made larger, and the dust bag opening must be fixed by the dust bag ring to facilitate the placement of the dust bag and the dust bag ring on the barrel body or the support ring. This makes the structure of the barrel body, support ring and dust bag complicated, and increases the cost. Utility Model Content

[0004] The purpose of the utility model is to provide a filtering device for a barrel-type vacuum cleaner, which has a dust bag cover arranged outside the filter and a dust bag opening detachably connected to the housing of the machine head, so that the dust bag is easy to load and unload, and the dust bag does not need a dust bag ring to be fixed, has a simple structure, and can effectively save costs.
