The filter 8 includes a vertical cylinder 801, the cylinder 801 is rotatably mounted on the turntable 7, a vertical guide rod 802 is installed in the center of the cylinder 801, the guide rod 802 can move up and down, and the upper part of the cylinder 801 is installed. A filter screen 803 is installed on the end surface, the middle of the filter screen 803 is fixedly connected with the upper end of the guide rod 802, and the lower end of the guide rod 802 is installed with a counterweight 804; Move up and down together.

In order to achieve dust washing, the described vacuum cleaner adopts a wet dust collector.

In order to stabilize the pressure and speed of the water from the drain hole 6, the inside of the upper box 2 is divided into an upper chamber 201 and a lower chamber 202 through a partition, and the bottom of the upper chamber 201 is installed with a lower chamber 202. Inside the water inlet pipe 203, a float valve 204 is installed at the bottom of the water inlet pipe 203.

In order to better receive the slag, the slag box 807 is a cylindrical box body, the upper end of the box body is provided with a funnel-shaped water-conducting edge 808, the interior of the box body is provided with a cross brace 810, the middle part of the cross brace 810 and the guide The rods 802 are connected by vertical connecting rods 809 .

In order to realize the up and down movement of the guide rod 802 , a collar 805 that can move up and down along the sleeve 4 is provided inside the cylinder 801 .

For better filtering, the filter screen 803 has a certain elasticity, and the weight block 804 is spherical.

In order to realize the rotation of the turntable 7, the rotating shaft 5 is driven by a motor to rotate.

In order to realize slag receiving, when the guide rod 802 is at the lowest position of its stroke, the lower end of the edge corresponds to the upper end of the cylinder 801 .

When the present invention is used, water is firstly added to the inside of the upper box 2, because the upper box 2 is divided into an upper chamber 201 and a lower chamber 202, and the lower chamber 202 controls the upper chamber 201 to enter the lower chamber through the float valve 204. The water in the chamber 202 and therefore the maximum water level of the lower chamber 202 can be controlled at a set value. In the initial state, the water level in the lower chamber 202 is clean, and the water will flow downward directly through the drain hole 6; It rotates together with the turntable 7; therefore, it can be ensured that the drain hole 6 always corresponds to a certain filter 8; the filtered water will enter the interior of the lower box 3.

And the pump starts to pump into the interior of the dust washer 1, so that the atomized water droplets, or the dense water flow contacts the dust, so that the dust is integrated into the water flow; the used water will be returned to the inside of the water tank through the pump.

At this time, the water has begun to contain impurities; it is necessary to start the motor, so that the motor drives the entire turntable 7 and the upper box 2 to rotate. During the rotation, filtering will be performed.

First, the rotation of the rotating shaft 5 will cause the filter 8 to revolve with the turntable 7. When each filter 8 revolves, since the gear 10 on the filter 8 meshes with the ring gear 11, each filter 8 will rotate on its own. When the filter 8 rotates, the torsion spring 9 between the filter 8 and the turntable 7 will be twisted, thereby storing elastic potential energy.

Since the right side of the bottom plate is provided with a slope-shaped convex segment 13, at the same time, this part of the inner gear 11 is a toothless segment 12, and the baffle plate 15 fixed on the lower case 3 can also block the drain hole that rotates to this part. 6. Therefore, when the filter 8 is rotated to this part, the slag throwing operation will be performed, so that the sundries on the filter screen 803 will be thrown off, and the filter screen 803 will be dredged. The specific working principle is as follows.

First of all, when the filter 8 is on the left side, the counterweight 804 at the lower end of the guide rod 802 will be placed on the bottom plate, and since the bottom plate on the left side is located lower, the middle of the filter screen 803 is lower than the filter screen 803 at this time. At this time, the lower end of the guide rod 802 is supported, and the force on the filter screen 803 is small, so the deformation of the filter screen 803 can be ignored, so that the gap of the filter screen 803 can be ignored. Small, the filtering effect is better. At the same time, the inverted cone can prevent liquid leakage and improve the filtering speed and filtering effect. At the same time, the slag box 807 is also at the low position of its stroke. Referring to FIG. 5, the water guiding edge 808 on the slag box 807 corresponds to the cylinder body 801 at this time, which can facilitate the entry of water into the cylinder body 801.

When the filter 8 rotates to the right with the turntable 7, the lower end of the guide rod 802 inside the filter 8 will be lifted up by the raised section 13 of the bottom plate, so that the guide rod 802 moves upward until the filter screen 803 The middle is higher than the periphery of the filter screen 803, that is, the filter screen 803 presents a tapered shape with a sharp top and a large bottom; at the same time, the guide rod 802 upward will cause the filter screen 803 to be deformed by force, that is, the gap of the filter screen 803 will become larger; The debris of the card is thrown out faster. At the same time, after the filter 8 is rotated to the right side, the gear 10 on the filter 8 will cooperate with the toothless segment 12 of the inner gear 11. At this time, the cylinder 801 will reverse at a high speed under the action of the torsion spring 9, so that the The sundries on the filter screen 803 are thrown into the feeding trough under the action of centrifugal force. In addition, when the filter screen 803 is thrown, the baffle plate 15 on the right side will block the drain hole 6, so that the filter 8 suspends the filtering operation. At the same time, after the guide rod 802 rises, it will drive the slag box 807 to rise together, so that the middle of the slag box 807 corresponds to the upper end of the cylinder 801, that is, the filter screen 803 corresponds to the middle of the slag box 807, and the thrown out debris will fall. In the slag box 807; collect.

After that, the filter 8 continues to rotate, and the guide rod 802 will be reset firstly under the action of gravity, so that the filter screen 803 and the slag box 807 are both restored to the original state.

Because the filter screen 803 has a small gap and the filtration speed is slow, by controlling the height of the liquid level of the lower chamber 202 in the upper tank 2, the flow rate and pressure of the drain hole 6 can be controlled to avoid untimely filtration; full.

The multiple filters 8 in this device work in a cycle, and during the cycle, the filter can be automatically stopped every time it is rotated to the right, and is cleaned by reverse deformation and stretching, and with centrifugal force, through the high speed of the torsion spring 9 Rotating, the fine debris on the filter screen 803 or the sticky debris such as mud can be thrown off and collected.

In this device, each filter 8 can automatically store power when revolving, and then release and reverse without additional power source, which is simple and efficient.

The circulating operation of the filter screen 803 in this device can keep the filtration in a continuous state, that is, the water flow in the entire water tank is always in a flowing state, which ensures the continuity of the water supply and prevents the cavitation gas caused by insufficient water in the lower tank 3. Binding, dust washer 1 does not work, etc.
