Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, and in particular to a dust bag clamping plate for a vacuum cleaner. Background Art

[0002] The dust bag clip of the vacuum cleaner serves as a connection between the dust bag and the vacuum cleaner. It opens when the vacuum cleaner inhales air and closes when the vacuum cleaner is turned off.

[0003] The structure of the existing vacuum cleaner dust bag clamp that controls the opening and closing of the baffle of the air inlet hole is generally a spring structure. The gap between the sealing rubber ring of the air inlet hole and the baffle is too large, and the contents of the dust bag are easy to fall out from the gap between the sealing rubber ring and the baffle. At the same time, the spring reset force is insufficient and the baffle is easy to deform due to its own gravity, resulting in the baffle being unable to fit the sealing rubber ring. In addition, it is difficult to return to the original state after long-term use, and the service life is short. Utility Model Content

[0004] In order to solve the above technical deficiencies, the utility model provides a dust bag clamping plate for a vacuum cleaner, which solves the problems that the blocking piece cannot fit with the sealing rubber ring of the air inlet hole and the blocking piece has insufficient resetting force.

[0005] The utility model discloses a dust bag clamping plate for a vacuum cleaner, comprising a plate body, wherein the plate body is provided with an air inlet hole, a fixing portion is provided at one end of the air inlet hole of the plate body, a baffle is rotatably provided on the fixing portion, the baffle is matched with the air inlet hole, a support column is provided on the side of the baffle facing outward, a metal pressing sheet is provided on the fixing portion, the metal pressing sheet extends to the upper side of the baffle, the cross-section of the metal pressing sheet is arc-shaped, the side of the metal pressing sheet away from the baffle is an outer arc surface, and the inner arc surface of the metal pressing sheet is pressed on the end of the support column; a sealing rubber ring is provided in the air inlet hole; a dust bag adhesive portion is provided on the outer periphery of the air inlet hole of the plate surface on one side of the plate body provided with the baffle; a first plug plate is provided at one end of the plate body, the first plug plate is provided with a fixing hole, and a first auxiliary plug plate and a second auxiliary plug plate are provided on the plate body on both sides of the first plug plate.

[0006] Furthermore, the first auxiliary plug plate and the second auxiliary plug plate are respectively provided with a hollow arrow pointing to the insertion direction.

[0007] Furthermore, a handle is provided on the plate body at the other end opposite to the first plug plate.

[0008] Furthermore, the first plug board, the first auxiliary plug board and the second auxiliary plug board are integrally injection molded with the board body.

[0009] The utility model provides a dust bag clamp for a vacuum cleaner, in which a baffle is reset by a metal pressing plate arranged on a fixed portion, and the metal pressing plate applies a resetting force to the baffle through a supporting column on the baffle, so that the baffle can better fit the sealing rubber ring of the air inlet hole; the cross-section of the metal pressing plate is arc-shaped, so that a large force is required to deform the metal pressing plate, thereby preventing the baffle from opening due to its own gravity, and the metal pressing plate has a strong restoring ability and high stability during repeated use.
