The elastic rubber strings 125 not only have the effect of separating the plastic bag 00 from the hemispherical cover 90 and leaving the plastic bag 00 in the dirt holding cylinder 120, but also have a certain capacity of blocking the plastic bag 00 in the dirt holding cylinder 120 from coming out from the port of the dirt holding cylinder 120.
In summary, the water inlet end of the arc-shaped water inlet pipe 40 is covered with a hemispherical cover 90, the density of the auxiliary water pipe 70 is less than that of water, and the auxiliary water pipe 70 is indirectly and fixedly connected with the hemispherical cover 90 through an outer pipe 100 and an arc-shaped connecting plate 110; when the water inlet end of the arc-shaped water inlet pipe 40 is covered by the plastic bag 00, the auxiliary water pipe 70 and the hemispherical cover 90 drive the plastic bag 00 to move when water is deficient, and the dirt containing cylinder 120 is arranged on the movement track of the hemispherical cover 90, so that the effect of automatically dredging the water inlet end of the arc-shaped water inlet pipe 40 is realized.
Further, a plurality of arc-shaped baffle rods are uniformly and fixedly arranged on one end face of the outer pipe 100 far away from the hemispherical cover 90, and the arc-shaped baffle rods are matched with the outer wall of the arc-shaped water inlet pipe 40; when the hemisphere cover 90 completely enters the dirt holding cylinder 120, the free end of the arc-shaped stop lever is still outside the dirt holding cylinder 120. The elastic rubber band rope 125 is prevented from being torn off when the outer tube 100 comes out of the dirt containing cylinder 120 again after the semispherical cover 90 and the outer tube 100 completely enter the dirt containing cylinder 120. Even when the hemisphere cover 90 completely enters the dirt holding cylinder 120, the free ends of the plurality of arc-shaped stopper rods outside the circumference of the water inlet end of the arc-shaped water inlet pipe 40 do not prevent water from passing through the sparse arc-shaped stopper rods into the arc-shaped water inlet pipe 40.
Example two
The difference between the second embodiment and the first embodiment is that:
the second embodiment further comprises a clamping plate 140, a connecting part 150 and a wing plate 160;
referring to fig. 5, 6 and 7, two pairs of clamping plates 140 are disposed in the dirt holding cylinder 120, the clamping plates 140 are arc-shaped, the clamping plates 140 are made of magnetic materials, and the adjacent surfaces of each pair of clamping plates 140 are opposite in magnetic attraction.
The connecting member 150 includes a first connecting rod 151 and a connecting string 152;
one end of the first connecting rod 151 is fixed on the inner wall of the dirt holding cylinder 120, one end of the first connecting rod 151 is fixed with the connecting rope 152, and the other end of the connecting rope 152 is fixedly connected with the clamping plate 140;
a plurality of connecting members 150 are provided on the side of each pair of clamping plates 140 remote from each other.
The extension plane of the adjacent surface of each pair of clamping plates 140 passes through the center of the dirt holding cylinder 120 (see fig. 6 and 7); a plurality of elastic rubber-band ropes 125 are parallel to the adjacent surfaces of each pair of clamping plates 140; (refer to fig. 5 and 8) the wing plates 160 are fixedly arranged at both sides of the outer wall of the outer tube 100, the wing plates 160 are arc-shaped, and the wing plates 160 are equal in radius and coaxial with the clamping plate 140.
When the outer pipe 100 enters the dirt-holding cylinder 120, the wing plates 160 on the outer side of the outer pipe 100 firstly pass through a plurality of elastic rubber-reinforced ropes 125 parallel to the wing plates 160, so that the wing plates 160 do not tear and break the elastic rubber-reinforced ropes 125; the wing plates 160 prop apart each pair of the sucking clamping plates 140, namely the wing plates 160 are positioned between the two sucking clamping plates 140, when the outer pipe 100 comes out of the dirt cylinder 120, the plastic bag 00 is clamped between the two sucking clamping plates 140, and the plastic bag 00 is prevented from going out from between two adjacent parallel elastic rubber-reinforced ropes 125 at the opening end of the dirt cylinder 120;
further, the ends of the adjacent two clamping plates 140 adjacent to the opening of the dirt holding cylinder 120 are away from each other, so that the wing plates 160 can enter between the adjacent clamping plates 140 more easily.
Further, in the test process, it is found that when the wing plate 160 and the plastic bag 00 enter between the two clamping plates 140, the two clamping plates 140 attract each other, so that the clamping plates 140 directly rub the plastic bag 00 with poor quality, and a row of openings is cut at the contact positions of the two pairs of clamping plates 140 and the plastic bag 00 with poor quality, so that the clamping plates 140 only clamp the part separated from the main body of the plastic bag 00.
When each wing plate 160 is located between two adjacent clamping plates 140, the magnetic poles of the wing plate 160 and the mutually adjacent sides of each clamping plate 140 are the same;
the wing plates 160 and the clamping plates 140 at both sides thereof generate repulsive magnetic force and are separated, so that in the process that the wing plates 160 enter between the pair of clamping plates 140 or come out from between the pair of clamping plates 140, the clamping plates 140 do not rub against the plastic bag 00 (see fig. 9), and the plastic bag 00 is always integrated; when the wings 160 are fully out of the waste canister 120, adjacent clamping plates 140 attract each other to clamp the portion of the plastic bag 00 therebetween.
Further, the distance between the two pairs of clamping plates 140 is 1.1 to 1.2 times the outer diameter of the outer tube 100.
Further, the length of the connecting string 152 is at least 0.5 times greater than the thickness of the wing 160.
