Abstract
Description
Technical Field
[0001] The invention relates to a self-locking dust filtering device. Background Art
[0002] The technical problem to be solved by the present invention is that the cyclone filter device of the vacuum cleaner is complicated, heavy and the ordinary filter element is difficult to clean. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a simple and convenient vacuum cleaner filtering device, which fundamentally solves the shortcomings of ordinary vacuum cleaner filtering devices.
[0004] The technical problem to be solved by the present invention can be achieved through the following technical solutions:
[0005] The self-locking dust filtering device includes a self-locking bracket and a dust filtering bag.
[0006] The self-locking bracket is composed of a folding rubber ring, a sealing partition and a cylindrical grid:
[0007] The folding rubber ring is composed of a large ring and a small ring, and the small ring can be compressed inside the large ring;
[0008] The sealing partition is circular or in other geometric shapes, with a through hole in the middle. The large circular ring of the folded rubber ring is fixed on the sealing partition, and the center of the circle corresponds to the center of the through hole in the sealing partition.
[0009] The two ends of the cylindrical grid are through holes, and one end is fixed in the small ring of the folded rubber ring.
[0010] The dust filter bag is a long open bag, and its length exceeds the cylindrical grid frame.
[0011] The dust filter bag is wrapped on the cylindrical grid, the opening of which is put on the small ring of the folded rubber ring, and the remaining part is stuffed into the through hole of the cylindrical grid. As long as the small ring of the folded rubber ring is pushed into the large ring, the dust filter bag can be automatically locked and sealed. To replace or clean the dust filter bag, you only need to pull the small ring of the folded rubber ring out of the large ring.
[0012] Due to the adoption of the above design scheme, the use, installation and cleaning of the self-locking dust filter device of the present invention are very simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments:
[0014] Figure 1 It is a schematic diagram of the overall structure of the present invention. DETAILED DESCRIPTION
[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0016] (See Figure 1 ) Self-locking dust filtering device, including: a self-locking bracket and a dust filtering bag.
[0017] The self-locking bracket consists of a folding rubber ring, a sealing partition and a cylindrical grid:
[0018] The folding rubber ring consists of a large ring 2 and a small ring 1. The small ring 1 can be compressed inside the large ring 2.
[0019] The sealing partition 3 is circular or in other geometric shapes, with a through hole in the middle. The large circular ring 2 of the folded rubber ring is fixed on the sealing partition 3, with the center of the circle corresponding to the center of the through hole on the sealing partition 3;
[0020] The two ends of the cylindrical grid 4 are through holes, and one end is fixed in the small ring 1 of the folded rubber ring.
[0021] The dust filter bag 5 is a long open bag, which is longer than the cylindrical grid 4.
[0022] The dust filter bag 5 is wrapped on the cylindrical grid 4, and the opening is put on the small ring 1 of the folded rubber ring, and the remaining part is stuffed into the through hole of the cylindrical grid 4. As long as the small ring 1 of the folded rubber ring is pushed into the large ring 2, the dust filter bag 5 can be automatically locked and sealed. After replacing or cleaning the dust filter bag 5, you only need to pull the small ring 1 of the folded rubber ring out of the large ring 2.
[0023] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
