Description
[ field of technology ]
The invention relates to the field of cleaning tools, in particular to a roller in a floor brush type dust collector and the dust collector.
[ background Art ]
A vacuum cleaner is a common cleaning apparatus and generally includes a dust collector, a filter assembly, and a vacuum source, and dust or debris is collected in the dust collector by suction from the vacuum source and filtering action of the filter assembly. At present, the brush hair of the floor brush, especially the brush hair of the rolling brush, is easy to wind filaments such as hair when running on the cleaned surface, and the filaments not only affect the dust collection effect, but also increase the loss of the rolling brush motor over time to reduce the service life of the dust collector. Accordingly, attempts to find various methods for solving the problem of the winding of the roll brush, such as the patent application documents CN201610279651.8 and CN201710520515.8, disclose a technical solution for cutting the winding by means of an axial movement of a blade provided in the drum. To better achieve the cutting effect, it is often an option to provide two blades for relative movement. However, this presents a new problem in that the two blades cannot be stuck too tightly or separated too loosely, or else cannot be moved relative to each other or the winding cannot be cut off, requiring the addition of specific elastic support mechanisms.
[ invention ]
The invention aims to provide a roller assembly comprising an elastic supporting mechanism, which can keep stable and smooth relative movement of a blade for cutting a winding object.
Another object of the present invention is to provide a vacuum cleaner including the above-mentioned drum assembly, which can solve the problem of the entanglement of the vacuum cleaner and improve the reliability.
One of the technical schemes of the invention is as follows:

The elastic supporting mechanism has various realization forms, and can be realized in a limited space inside the roller as long as the elastic pressing of the cutting blade can be realized.
Further, the roller assembly comprises a roller divided into a plurality of roller sheets, and a containing groove for containing the cutting blade is formed between the adjacent roller sheets. Since the cutting blade, the elastic supporting mechanism and the like are required to be installed inside the drum, the drum assembly is preferably divided into a plurality of drum sheets, each drum sheet is assembled with each other according to the original dividing surface to restore the shape of a cylindrical object of the drum, and a groove is formed between the adjacent drum sheets to accommodate the cutting blade. The roller sheets can be arranged into a plurality of separated or movably connected sheets according to actual conditions.
Further, the cutting blade is divided into a movable blade capable of moving relative to the drum wall and a fixed blade fixed relative to the drum wall, and the movable blade and the fixed blade are oppositely arranged in the accommodating groove; the edges of the movable blade and the fixed blade are provided with tooth edges with the same shape and position. The cutting blade is divided into a movable blade and a fixed blade, and a notch for cutting a winding is formed between the tooth edges of the movable blade and the fixed blade, so that the cutting effect can be improved.
Further, a ball tray, or a needle roller tray is provided between the movable blade and the inner wall of the drum adjacent to the movable blade. During the operation of the roller with the cutting blade of the dust collector, the action frequency of the blade for cutting the filiform objects wound on the roller is often higher, so that the elastic supporting mechanism for clamping the blade is easily worn, and the wear can be reduced to be negligible by selecting the assembly formed by the ball or the ball and the ball tray or the assembly formed by the needle and the needle tray, thereby prolonging the service life and improving the reliability.
Further, the ball tray is provided with a ball groove for accommodating the ball, and the needle roller tray is provided with a needle roller groove for accommodating the needle roller.
Further, the balls or the needle rollers are simultaneously contacted with the movable blade and the ball grooves or the needle roller grooves. Each blade is supported by more than two balls or rolling pins, when the blade performs cutting action, the blade slides on the balls or rolling pins, and the balls or rolling pins roll in the grooves, so that the blade is supported, and the abrasion is reduced.
Further, the ball tray or the needle roller tray is fixedly connected with the inner wall of the roller through a fixing piece. The tray needs to be fixed with the roller, and the tray can be realized through the cooperation of a simple fixing piece and a corresponding fixing part arranged inside the roller.
Further, the collision beads are inserted into holes formed in the inner wall of the roller through cylindrical sections of the collision beads and fixedly connected with the inner wall of the roller. When the elastic supporting mechanism adopts the collision beads, the movable blade is supported by more than two collision beads, and the collision beads are embedded on the inner wall of the roller at one side of the movable blade. Thus, when the blade performs cutting action, the blade slides on the steel ball of the collision bead. The elastic piece is embedded in the spring ball, so that the blade can easily and freely perform cutting action under the action of the driving mechanism.
The technical scheme has the following beneficial technical effects:
the roller assembly can keep stable and smooth relative movement of the blade for cutting the windings, utilizes the prior dead space in the roller, can reduce the wear rate of parts to a negligible state, is simple, easy and reliable, has low cost, and is an effective way for solving the problem of winding the floor brush of the dust collector.
The other technical scheme of the invention is as follows:
