Definitions
- the present invention relates to a vacuum cleaner manufacturing technique, and more particularly to a centrifugal cleaner air and dust separation device. Background technique
- vacuum cleaners are widely used in the market to separate air and dust.
- centrifugal vacuum cleaners with only a single-stage separation device generally have poor separation effect, and fine dust is easily discharged with air to cause secondary pollution. .
- the application number I applied for is "200510049880. 2", "Integrated two-part vacuum cleaner dust cup", which uses dusty air to enter from the tangential direction of the dust cup. After a cyclone separation, it is deposited on the bottom of the dust cup. In the dust chamber, fine dust enters from the air inlet of the separator consisting of the rotating array of blades, and is separated by cyclone again. The dust is deposited on the outer tube of the separator and the inner dust chamber connected to the bottom of the short tube.
- the two separate vacuum cleaner dust cups have been greatly improved compared with the prior art, but a small amount of fine dust is adsorbed on the filter plate of the dust cup air outlet with the air, and after being used for many times, in the filter sheet The accumulation of fine dust is gradually increasing, resulting in a decrease in the working efficiency of the vacuum cleaner and affecting the dust suction effect.
- vacuum cleaner vacuum cup In order to further improve the separation effect of air and dust, I have repeatedly studied and designed a vacuum cleaner vacuum cup with better separation effect.
- the application number is "200620101407. 4", "vacuum cleaner cyclone type dust cup", which uses air and After the dust enters from the tangential direction of the dust cup, the dust is deposited on the dust collecting chamber at the bottom of the dust cup by a cyclone, and then separated by the secondary cyclone of the plurality of spiral pieces and the rotating blades in the separator, and the fine dust is separately deposited in the isolation.
- the bottom dust collecting chamber at the bottom of the extension tube and the bottom dust collecting chamber connected to the inner tube and the outer tube.
- the dust separated by two or three times is deposited in the dust collecting chambers disposed at different positions inside the dust cup. They seem to be deeply hidden in the labyrinth of the dust cup, so the dust is dumped after use. It is very troublesome to clean. The parts in the dust cup must be taken out one by one, and the dust in the dust collecting chamber should be dumped one by one, which causes trouble for the user to use and clean. Moreover, there are many internal components in the dust cup, and the manufacturing process is relatively complicated. Furthermore, there are three dust collecting chambers that need to occupy a certain space for three separations. The height of the cup must be increased to achieve the desired separation effect. Therefore, the above two types of dust cups are more suitable. For vertical vacuum cleaners, it is necessary to provide a cyclone separation device with a more significant separation effect for a horizontal vacuum cleaner with a relatively short profile.
- the existing dust cups generally have a drawback, that is, the vacuum cleaner tends to suck the fine dust when it is restarted after the intermittent operation, so that the fine dust is sucked up and attached to the filter, which will increase over time.
- Motor load affecting the dust suction effect, in order to overcome the above defects, people often use the method of increasing the height between the bottom of the separator and the dust collecting chamber of the dust cup to prevent the fine dust from sucking and increasing the capacity of the dust collecting chamber, but the separation is installed.
- the dust cups of the device are relatively high, which increases the size and manufacturing cost of the vacuum cleaner. Summary of the invention
- the object of the present invention is to provide a vacuum cleaner dust cup with better structure, convenient cleaning, low manufacturing cost, remarkable dust collecting effect, and better separation effect for the horizontal vacuum cleaner. And the separation effect is good, the volume is small, and it is not easy to produce fine dust sucking, to meet the development and manufacture of various vacuum cleaner products.
- a secondary cyclone type dust cup for a vacuum cleaner comprising a cup body, a dust cup air outlet opening on the cup body, a dust cup air inlet tangential to the peripheral wall of the cup body, and a separator disposed in the cup body, the separating
- the outer cylinder body is provided with a separator air inlet opening below the air inlet of the dust cup, and a partition cover is arranged below the air inlet of the separator, and the bottom of the outer cylinder body is connected with the isolation cover, and the top of the outer cylinder body
- the connection bracket is connected to the support body, and the connection bracket is supported on the cup body.
- the outer cylinder body is provided with an inner cylinder body coaxially disposed, and an inner cylinder air inlet opening is provided at an upper portion of the inner cylinder body and above the air inlet of the separator, the inner cylinder
- the top of the body is connected with the connecting bracket, and the lower part thereof passes through the isolation cover, and the air inlet of the dust cup communicates with the air outlet of the dust cup through the air inlet of the separator and the air inlet of the inner cylinder.
- the inner wall of the inner cylinder is provided with a conical cylinder with a large upper and lower sides, and the bottom of the conical cylinder has a certain distance from the bottom of the inner cylinder to form an inner dust collecting chamber.
- the bottom of the conical cylinder is provided with an isolation pocket, and a part of the peripheral wall of the isolation pocket is connected to the outer wall of the conical cylinder through a connecting rib, and an annular gap is formed between the inner wall of the isolation pocket and the outer wall of the conical cylinder.
- the air inlet of the separator is evenly distributed on the circumferential wall of the lower portion of the outer cylinder, and is rectangular or circular.
- the inner cylinder air inlet includes two or more passages whose axial direction is tangent to the inner cylinder inner wall
- the inner cylinder air inlet is formed by rotating or evenly arranging a plurality of blades provided on the inner cylinder in an annular array.
- the bottom of the connecting bracket is provided with a central hole, and a short tube is connected below the short tube.
- the inner diameter of the short tube is smaller than the inner diameter of the inner cylinder, and the upper edge of the conical cylinder is lower than the lower edge of the short tube.
- the connecting bracket is integrally formed with the outer cylinder body and the inner cylinder body.
- the positive progress of the invention is as follows: After the dusty air is separated by the secondary cyclone, the dust falls on the inner and outer dust collecting chambers at the bottom of the dust cup, and the cup lid can be poured and cleaned, which is convenient.
- the structure is simpler than the prior art, and the manufacturing cost is reduced.
- the experimentally tested the dust separation effect is more remarkable, and the cup height is suitable for the horizontal vacuum cleaner; because an isolation pocket is connected at the lower end of the conical cylinder of the separator.
- the method can effectively avoid the phenomenon that the vacuum cleaner sucks the fine dust when the working intermittently stops again when the dust is collected in the dust collecting chamber, thereby improving the vacuuming effect and the service life of the vacuum cleaner.

- Figure 4 is a perspective view of the separator of Figure 1 connected to a connecting bracket. detailed description
- a secondary cyclone separation dust cup of a vacuum cleaner comprising a cup body 11 , is formed on a dust cup air inlet 3 tangential to a peripheral wall of the cup body 11 , and is provided in a dust cup covering the cup body Cover the dust cup air outlet 1 and the separator placed in the dust cup.
- the separator is provided with an outer cylinder 5, and an inner cylinder 12 is coaxially mounted at the center of the outer cylinder 5.
- the upper portion of the outer cylinder 5 is connected to the connecting bracket 15.
- the peripheral wall of the lower end of the outer cylinder 5 is provided with a separator air inlet 6 which is lower than the air inlet 3 of the dust cup.
- the air inlet 6 of the separator can be rectangular, circular and arranged in a uniform circular shape.
- the connecting bracket 15 has an upper opening and a small opening, and a disc-shaped bottom is provided with a central hole 16, and a short tube 14 is connected below.
- a flared cover 7 is provided below the air inlet 6 of the separator, and the bottom of the outer cylinder 5 is isolated from the bottom The cover 7 is connected. '
- the top of the inner cylinder 12 is connected to the connecting bracket 15 and the bottom passes through the insulating cover 7 to the bottom of the dust cup.
- the connecting bracket 15 is connected to the inner cylinder 12 of the separator and the top of the outer cylinder 5, and is supported on the cup body 11. In the present embodiment, it rests on the cup opening of the dust cup body 11.
- the inner wall of the inner cylinder 12 is provided with a conical cylinder 10 having a large upper opening and a small lower opening, and the upper edge of the conical cylinder 10 is lower than the lower edge of the short tube 14.
- the bottom of the conical cylinder 10 is spaced from the bottom of the inner cylinder 12 to form an inner dust collecting chamber 9 at the bottom of the inner cylinder 12.
- a spacer pocket 18 is attached to the bottom of the conical cylinder 10, and a portion of the peripheral wall of the spacer pocket 18 is joined to the outer wall of the conical cylinder 10 via the connecting rib 19.
- An annular gap 20 is left between the inner wall of the spacer pocket 18 and the outer wall of the conical cylinder 10, that is, the upper edge radius of the spacer pocket 18 is larger than the radius of the lower edge of the conical cylinder 10, thereby forming the annular gap 20.
- the upper end of the inner cylinder 12 is provided with an air inlet 2 which is tangential to the peripheral wall and which may be composed of two or more passages whose axial direction is tangent to the peripheral wall of the inner cylinder 12.

- the air duct connected to the air inlet of the electric fan is connected with the air outlet 1 of the dust cup, and the switch is activated. After the motor works, a negative pressure is generated in the dust cup, and the dusty air enters the dust from the air inlet 3 of the dust cup. The inner cavity of the cup.
- the dust is pushed toward the peripheral wall of the cup 11 by the centrifugal force and the gravity and falls to the outer dust collecting chamber 8 at the bottom of the dust cup. Since the dust that has fallen into the outer collecting chamber 8 due to the isolation of the insulating cover 7 is hardly re-rolled by the influence of the upper spiral airflow, most of the dust is separated.
- the air of body 12 also produces a swirling airflow. Since the inner diameter of the upper chamber 13 of the inner cylinder 12 is large, it enters the conical cylinder 10 downward. Because the inner diameter of the upper cavity of the conical cylinder 10 is large, the inner diameter of the lower end is small.
- the wind pressure of this part of the airflow increases, the flow velocity is accelerated, and the centrifugal force again separates a small amount of fine dust mixed in the air, and the fine dust is turned toward
- the inner wall of the conical cylinder 10 falls to the inner wall of the isolation pocket 18, and the fine dust that is rotated by the inertia is impacted by the airflow, and passes along the inner wall of the isolation pocket 18 through the annular gap between the outer wall of the conical cylinder 10 and the inner wall of the isolation pocket 18.
