Description

a cyclone vacuum cleaner

technical field

The utility model relates to a vacuum cleaner, in particular to a cyclone vacuum cleaner

Background technique

At present, most of the household vacuum cleaners on the market adopt the principle of filtration. The motor drives the fan impeller to rotate at high speed, so that the air is discharged at high speed, and the air in the dust collection room at the front end of the fan continuously replenishes the air in the fan, resulting in an instantaneous vacuum in the dust collection room, which is formed with the external atmospheric pressure. Negative pressure difference, under the action of this pressure difference, the dusty air is sucked in, filtered by the dust filter, and clean air is discharged. Such a vacuum cleaner has a complex structure, many wearing parts, is not easy to clean, cannot handle humid gas, requires a lot of investment in the later stage, has low efficiency, and is noisy. If the cyclone dust collector is applied to the household vacuum cleaner, these problems will be solved. the

Utility model content

The technical problem to be solved by the utility model is to provide a cyclone vacuum cleaner with simple structure, high efficiency and high reliability. the

The technical problem to be solved by the utility model is realized by adopting the following technical scheme. The structure of the vacuum cleaner consists of a suction head (1), a hard pipe (2), a hose (3), a cyclone separator (4), and a dust box (5) , pipeline (6), impeller device (7), motor (8), these parts of outer casing (9). The motor is connected to the impeller, which is wrapped by a cylindrical shell and located below the overall vacuum cleaner; the impeller device (7) is connected to the pipe (6); the pipe extends vertically upwards and then bends 180°, and the rear mouth is connected downwards to the outlet of the cyclone separator (4) ;The bottom of the cyclone separator is connected to the dust collection box (5), and a ferrule joint is used between the cyclone separator and the dust collection box; a hose (3) is connected to the inlet of the cyclone separator; the hose extends out of the outer box of the vacuum cleaner (9 ) to connect the telescopic hard tube (2); the telescopic hard tube is threadedly connected to the suction head of the vacuum cleaner (1). the

The biggest feature of this vacuum cleaner is the use of the cyclone separator and the improvement of the dust collection device. First, a cyclone separator is added in front of the impeller working device, which can separate the air and dust by centrifugal force, and largely avoid the blockage of the filter device, thereby Greatly improved the service life of the product. It is not limited by the concentration and temperature of dusty gas. There are no special requirements for the physical properties of the dust. Furthermore, the dust collection box is detachable, which is easier to clean than dust collection bags. At the same time, the dust bag needs to be purchased irregularly, while the dust box can be used repeatedly. The dust collection box is made of PC plastic with good light transmission, and the amount of dust in the dust bucket can be seen at any time for timely cleaning. the

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations. the

When the cyclone vacuum cleaner is working, the motor (8) is turned on to make the impeller in the impeller device (7) rotate to generate a pressure difference in the pipeline, and the dust is sucked in from the suction head (1) and passed through the hard tube (2) and hose (3). ) to the cyclone separator (4), the airflow will change from linear motion to circular motion when entering. Most of the swirling air flow spirals downward from the cylinder along the wall of the device and flows toward the cone. The dust-containing gas generates centrifugal force during the rotation process, and the dust particles with a density higher than the gas are thrown to the wall of the container. Once the dust particles come into contact with the wall of the container, they lose their inertia and fall along the wall by the momentum of the entrance velocity and the downward gravity, and enter the dust collection box (5) through the ash discharge pipe. Due to the contraction of the cone, it moves closer to the center of the dust collector. According to the principle of "rotational moment" constant, its tangential speed increases continuously. When the airflow reaches a certain position at the lower end of the cone, it continues to make a spiral movement from bottom to top, that is, the internal swirling airflow. Finally, the purified gas is discharged out of the device through the exhaust pipe. the
