As shown in fig. 1 to 5, a suction assembly 100 of a vacuum cleaner according to an embodiment of the present invention includes a connection pipe 110 and a suction attachment 130. Specifically, the water absorbing attachment 130 is connected to and communicates with the connection pipe 110, and at least one of the water absorbing attachment 130 and the connection pipe 110 is provided with a water stop portion 120 to block a water flow flowing from the connection pipe 110 to the water absorbing attachment 130. It is understood that the water stopping part 120 may be provided on the water absorbing attachment 130, and may also be provided on the connection pipe 110; of course, the water stopping part 120 may be plural, at least one of which may be provided on the water absorbing attachment 130, and at least one of which may be provided on the connection pipe 110.
It should be noted that the water stop portion 120 can function as a check valve, and water can flow from the water absorbing attachment 130 to the connection pipe 110. Specifically, when the water suction operation is stopped, the water in the connection pipe 110 may flow back to the water suction attachment 130, and when the part of the water flows to the water stopping portion 120, the water stopping portion 120 is blocked by the water stopping portion 120, so that the part of the water flow cannot return to the water suction attachment 130.
According to the utility model discloses the subassembly 100 that absorbs water of dust catcher through at least one setting stagnant water portion 120 in the annex 130 that absorbs water and connecting pipe 110, can utilize the stagnant water portion 120 structure that has the check valve function, backstop reverse rivers, and then can prevent secondary pollution effectively, promotes the result of use of dust catcher.
According to some embodiments of the present invention, as shown in fig. 2 and 3, the water absorbing attachment 130 has a first end 131, and the connection pipe 110 has a second end 111 connected and communicated with the first end 131. That is, the first end 131 of the water absorbing attachment 130 is connected to the second end 111 of the connection pipe 110, and the water absorbed by the water absorbing attachment 130 can flow into the connection pipe 110 through the first end 131 and the second end 111.
As shown in fig. 3, the first end 131 is nested with the second end 111, on one hand, the connection stability between the water absorbing attachment 130 and the connecting pipe 110 can be improved; on the other hand, the communication sealing property between the water absorbing attachment 130 and the connection pipe 110 can be improved, so that defects such as water leakage at the connection position of the first end 131 and the second end 111 can be prevented. Further, the second end 111 may be sleeved on the first end 131, and the water stopping portion 120 is inserted into the first end 131. Thereby, the water stop portion 120 is conveniently attached to the water absorbing attachment 130.
As shown in fig. 3 and 5, the water stop portion 120 may include a plug portion 121, a stopper portion 122, and a gap 1203 for facilitating the liquid to pass through.

When water flows from the water sucking attachment 130 to the connection pipe 110, the water may flow toward the connection pipe 110 through the slits. When the suction operation of the cleaner is stopped, the water in the connection pipe 110 flows to the suction attachment 130 by gravity, but the water flow is stopped by the water stop part 120, and the water flow cannot return to the suction attachment 130. In the position of the gap of the water stop part 120, since the width of the gap is small, the gap can be sealed by the water inside the gap under the tension of the water, and the water flow can be blocked from returning to the water suction attachment 130.
Specifically, the liquid flowing backwards contacts the first stopper 1201 and the second stopper 1202, and then the gravity of the liquid is transferred to the first stopper 1201 and the second stopper 1202, wherein the first stopper 1201 and the second stopper 1202 are relatively inclined, so that the force applied to the first stopper 1201 and the second stopper 1202 is resolved, and a partial force of the force is directed toward the direction in which the gap 1203 is closed, so that the gap 1203 can be closed under the action of the force applied to the first stopper 1201 and the second stopper 1202.
Further, as shown in fig. 2 and 3, a water containing space may be formed between an outer wall surface of the water stopping part 120 and an inner wall surface of the connection pipe 110, and when the suction operation of the cleaner is stopped, the water in the connection pipe 110 may flow toward the suction attachment 130 by gravity, but the water flow is stopped by the water stopping part 120, and the stopped water flow is contained in the water containing space, so that the water flow may not return to the suction attachment 130. Further, the stopper 122 may be an elastic member, and the connecting tube 110 may be a hard plastic member.
As shown in fig. 3, the insertion part 121 may be interposed between the first end 131 and the second end 111 for facilitating the installation of the water stop part 120. It can be understood that the water-stopping portion 120 can be mounted to the water absorbing assembly 100 by using the first end 131 and the second end 111, so that not only the connection stability between the water-stopping portion 120 and the water absorbing attachment 130 and the connection pipe 110 can be improved, but also the fixing structure for fixing the water-stopping portion 120 can be saved, thereby reducing the number of parts of the water absorbing attachment 130 and saving the production cost.
In some embodiments, as shown in fig. 3, the water absorbing attachment 130 includes two parts, a first part far away from the cleaning surface and a second part near the cleaning surface, the first part is provided with the first end 131, the first part is provided with the clamping lug 132, the clamping lug 132 extends along the circumferential direction of the water absorbing attachment 130, the second part is provided with the flange 112, the flange 112 extends along the circumferential direction of the connecting pipe 110, the flange 112 and the clamping lug 132 are stacked, one of the flange 112 and the clamping lug 132 is provided with the plug pin 113, and the other is provided with the plug slot 133 for receiving the plug pin 113. Two pairs of securing of the first and second portions are achieved by the cooperation of the flanges 112 and the snap lugs 132.
As shown in fig. 4, the end of the water absorption accessory 130 is provided with a first scraping bar 134 and a second scraping bar 135, the water absorption accessory 130 is provided with a liquid inlet 1301, and the liquid inlet 1301 is located between the first scraping bar 134 and the second scraping bar 135.
