Description

Vacuum cleaner dust bucket with easy-to-open bottom cover

technical field

The invention belongs to the field of vacuum cleaners, and in particular relates to a dust collecting barrel of a vacuum cleaner whose bottom cover is opened by driving a lock bolt connected to the handle through a brake line to move back and forth through a handle installed under the handle.

Background technique

Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe.

When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air inside the vacuum cleaner, forming an instantaneous vacuum inside the vacuum cleaner, and forming a relatively high negative pressure difference with the outside atmosphere. Under the action of this negative pressure difference, the dust near the suction head and the air are sucked into the dust bucket in the body through the suction port. The air containing dust is filtered in the dust collecting barrel of the machine body, and then discharged from the air outlet to the outside of the vacuum cleaner. In this way, the effect of removing dust and cleaning the ground is achieved. The suction rate of the vacuum cleaner is divided into several operable and controllable gears, which are suitable for the working surface of different cleaning objects such as the floor, bed surface, carpet, sofa, and corner, so as to better suck the dust everywhere.

According to the shape of vacuum cleaners, they can be divided into vertical vacuum cleaners, horizontal vacuum cleaners and portable vacuum cleaners. For vacuum cleaners, whether it is an upright vacuum cleaner, a horizontal vacuum cleaner or a portable vacuum cleaner, there is a dust collection bucket inside the vacuum cleaner body that collects dust and foreign objects. The dust and foreign objects accumulated in the dust collection bucket need to be removed regularly to ensure the vacuum cleaner normal use.

Fig. 1 is a three-dimensional view of the structure of the dust collecting barrel in the prior art; Fig. 2 is an enlarged view of part A in Fig. 1; Fig. 3 is a schematic diagram of the open state of the bottom cover of the dust collecting barrel in the prior art. As shown in Fig. 1, Fig. 2 and Fig. 3, the dust collecting barrel of the prior art includes a barrel body 1; a bottom cover 2 connected to the bottom end of the barrel body 1; a linkage rod 3 arranged on the barrel body and an upper end of the linkage rod Handles 4 on both sides; two protruding blocks 6 arranged on the outer peripheral wall of the barrel bottom; two connecting parts 5 connected to the edge of the bottom cover with a gap in the middle. The middle portion of the connecting portion 5 protrudes to form protrusions 7 on both sides. The inner upper ends of the two stoppers 6 form arc-shaped depressions 8 .

As shown in FIG. 2 , when the bottom cover is closed, the protrusion 7 of the connecting portion 5 is stuck in the recess 8 of the stopper 6 . The linkage rod 3 can move up and down along the outer peripheral wall of the barrel.

When the dust collection bucket of the vacuum cleaner is full of dust and garbage, you need to open the bottom cover of the dust collection bucket to dump the garbage. At this time, hold the middle part of the index finger on the lower end of the handle 4, press the upper end of the connecting rod with the thumb, press the connecting rod downwards firmly, and the connecting rod moves downward. Because the lower end of the linkage rod contacts the connecting part 5, the connecting part is subjected to downward force and disengages from the baffle plate 6, the bottom cover is opened, and the dust is poured out. Release your thumb and the linkage lever returns to its original position. After emptying the garbage, lift the bottom cover up with your hands. When the connecting part passes through the middle of the two stoppers, it is squeezed and slightly tightened towards the middle, so the protrusion 7 squeezes through the stopper and gets stuck in the depression 8. The bottom cover close.

The opening structure of the bottom cover of the prior art dust collecting bucket needs a lot of force to open the bottom cover, which is difficult to open and poor in operability. Moreover, the sliding of the connecting rod requires the barrel body to have a smooth and uniform peripheral wall, and in the production process, the uneven wall thickness of the surrounding wall of the barrel body is very likely to occur, which affects the sliding of the connecting rod, so the bottom cover is more difficult to be opened.
