Description

Dirt and dust separating device and dust collector

Technical Field

The utility model relates to a dust catcher technical field, concretely relates to dirt separator and dust catcher.

Background

Vacuum cleaners are very common electrical appliances on the market. Through set up vacuum motor in vacuum cleaner, will carry with the dirty air suction of dirt inside the dust catcher, through the separation back, the dirt persists in vacuum cleaner the inside, and the clean air after the filtration is discharged to the external world.

In the prior art, in order to separate dust, a bag type separator or a cyclone separator is generally arranged inside a vacuum cleaner.

In the case of the bag-type separator, the main structure of the bag-type separator is a dust bag with filtering capability installed inside the dust collector, and the bag is provided with small holes for filtering out the particulate matters (dust and dirt) carried in the airflow passing through the dust bag. However, after a period of use, the small holes on the dust bag can be rapidly blocked by dirt, so that the suction force of the dust collector is reduced; after the dust collecting bag is filled, the old bag needs to be thrown away and replaced by a new bag, so that resource waste and environmental pollution are caused, and the use cost of a user is increased; the dirt separation efficiency is low. For the cyclone separator, the airflow carrying dust can form cyclone inside the dust collector, and the dust particles have relatively large mass and can be in friction collision with the wall of the container and fall into the dust collecting box under the action of centrifugal force, so that the aim of separating the dust and air is fulfilled. However, the cyclone separator consumes a large vacuum pressure, requires a large vacuum motor power, and has a strong noise ratio during operation, which affects user experience.

The prior art provides a dust and dirt separator comprising a foraminous disc at the air flow outlet of the collecting chamber and a motor for rotating the disc. The disk is arranged to rotate about an axis of rotation and includes apertures through which a cleaned airflow passes. The dirt-laden air stream enters the chamber and contacts the rotating turntable, which applies a tangential force to the air stream so that dirt entrained in the air stream moves radially along the surface of the turntable towards the edge of the turntable. During this process, the air flow will exit through the small holes in the turntable, and the dirt therein will continue to move towards the outer radial edge and collect at the bottom of the chamber due to its greater inertia. Compared with a cyclone separator, the separator consumes less vacuum pressure and can be matched with a vacuum motor with less power and noise.

However, in operation of such separators, the dirt-laden air stream impinges directly on the discs. The large mass particles in the dirt will cause damage to the turntable and affect the balancing movement of the turntable.

The inclination angle of the dust collecting chamber filter screen 6 in the dust collecting chamber 4 is not limited, in the embodiment, the dust collecting chamber filter screen 6 and the longitudinal axis of the dust collecting chamber can be arranged in an acute angle, an obtuse angle or a right angle. As shown in fig. 1, preferably the axis of the dust chamber screen coincides with the axial direction of the dust chamber 4. Through foretell mode of setting up, can realize that dust collection chamber filter screen 6 blocks the dirt on furthest to help improving the purifying effect to the dirt.

In this embodiment, the center of the filter screen of the dust collecting chamber is protruded toward the air inlet 5.

When carrying out the dirty air current of dirt and flowing out and use filter screen 7 position from dust collection cavity filter screen 6, can and filter screen 7 between the collision, because the center of filter screen 7 takes place the protrusion, consequently the side of filter screen 7 will be the obtuse angle setting with between the flow direction of dirt, after the side collision of dirt and filter screen 7, certain frictional force will be applyed to dirt to filter screen 7, make dirt follow filter screen 7 and move, the diversion can take place under the guide of filter screen 7 simultaneously, under the effect of the rotation centrifugal force of filter screen 7, turn to the lateral wall of main part 1 and move.

Through the arrangement mode, the blockage of dust to the filter screen 7 can be effectively reduced, so that the service life of the filter screen 7 is prolonged, the filter screen 7 is kept at a low wind resistance all the time, and the power of the vacuum motor can be lower and the volume of the vacuum motor can be smaller.

In particular, the shape of the dust collection chamber screen 6 itself is not overly limited, and it may be arranged in an arc shape, as a preferred embodiment, the dust collection chamber screen 6 is arranged in a cone shape.

In this embodiment, the aperture of the dust collecting chamber filter screen 6 is larger than the aperture of the filter screen 7. Through foretell mode of setting up, can realize the prefilter of dust collection chamber filter screen 6 to dirt, then realize the meticulous filtration to dirt through filter screen 7 to help reducing the load of filter screen 7 self.

In this embodiment, as shown in fig. 1, the method further includes: the filter screen motor 3 is arranged in the main body 1, an output shaft is arranged on the filter screen motor 3, the filter screen 7 is arranged on the output shaft, and a filter screen motor support 31 is arranged on the inner wall of the main body 1.

Through foretell setting mode, can realize the stable rotation of filter screen 7 self to help improving the interception effect of filter screen 7 to the dirt.

In this embodiment, a screwing female end 11 is provided on one of the dust collecting chamber 4 and the inside of the main body 1, a screwing male end 44 is provided on the other of the dust collecting chamber 4 and the inside of the main body 1, and the dust collecting chamber 4 and the main body 1 are detachably connected through the screwing male end 44 and the screwing female end 11.

Through foretell mode of setting for can dismantle the setting between dust collecting chamber 4 and the main part 1, after dust collecting chamber 4 and the inside collection a quantitative dirt of main part 1, through dismantling alright in order to realize pouring out dirty to the dirt.

Meanwhile, sealing rings can be correspondingly arranged at the screwing male end 44 and the screwing female end 11, and sealing operation can be realized by arranging the sealing rings, so that the condition that the air flow exchange is generated between the connection part between the dust collection cavity 4 and the main body 1 and the outside is avoided, and normal purification operation is influenced is avoided.

Further, the dust collecting chamber 4 includes: a dust collecting barrel 42 in which the turntable separating device is arranged; an end cover 43 disposed at one end of the dust collecting barrel 42 far away from the main body 1, a rotating shaft 431 disposed on the end cover 43, a connecting column 421 suitable for the rotating shaft 431 to be embedded into the dust collecting barrel 42, and the end cover 43 and the dust collecting barrel 42 hinged with each other.

When the amount of dirt in the dust collection chamber 4 is large, the dust collection barrel 42 is opened by controlling the end cover 43, so that the dirt can be easily poured out. Specifically, when the dust and dirt needs to be poured out, the end cover 43 itself is still connected to the connecting column 421 of the dust collecting barrel 42, so that the pollution to the surrounding environment caused by placing the end cover 43 at other positions can be avoided.
