Dust bucket compression device

Abstract

The invention discloses a compressing device for a dust collection barrel, which comprises a fixed compressing plate fixed in the dust collection barrel and a rotary compressing plate which can be rotationally arranged in the dust collection barrel, wherein the fixed compressing plate and the rotary compressing plate are coaxially arranged along the axis of the dust collection barrel; meshing grooves are symmetrically formed on the inner side wall of the cavity at the tail end of a rotary compressing shaft; the output shaft of a compressing motor is fixedly provided with a connecting head; meshing teeth matched with the meshing grooves are formed on the connecting head; and the connecting head is provided with at least one clamping boss matched with the meshing grooves, and the clamping boss is lower than the meshing teeth. The structure of the connecting head of the compressing device for the dust collection barrel is simple and easy to realize; the clamping boss and the meshing teeth are arranged at different heights, so the bottom cover is easy and convenient to open and close, and the stress uniformity of the rotating shaft is enhanced; and thus, the output torque of the compressing motor is utilized to a maximum degree, the rotating plates can rotate stably and normally, and product quality is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical dust removal, in particular to a transmission head structure of a dust bucket compression device of a vacuum cleaner. Background technique [0002] In general, a vacuum cleaner is a device for sanitation that uses vacuum pressure generated by a vacuum motor installed in its body to suck dust-containing gas and then filters the dust in the gas. [0003] figure 1 It is a three-dimensional schematic diagram of a vacuum cleaner in the prior art. Such as figure 1 As shown, the vacuum cleaner includes a vacuum cleaner body 1 with a suction force generator therein, a dust collector for separating dust from the introduced air and storing the separated dust; The suction nozzle 9 passed through; and the electric wire 4 for power supply; the handle 3 and the roller 8 that allow the user to operate the vacuum cleaner; the connecting hose 5 that connects the suction nozzle 9 to the vacuum cleaner body 1,...

Problems solved by technology

[0007] However, since only one meshing tooth structure is arranged on the connecting head, when the compression drive motor drives the connecting head to rotate and then drives the rotating piece to rotate and compress, the rotating shaft is only stressed on one side, which will cause the rotating piece to fail due to eccentricity. Normal operation affects machine quality

Simply increasing the number of meshing teeth will increase the difficulty of mating the meshing teeth with the meshing groove
