To facilitate the detachable connection of the filter assembly 120 and the water return plate 110, in an exemplary embodiment, referring to fig. 2 and fig. 8 to 10, the filter assembly 120 is formed with an insertion rib 123 and a first clamping rib 124 at two ends along the height direction thereof, the water return plate 110 is formed with an insertion groove 110e and a second clamping rib 112 distributed along the height direction thereof, and the insertion rib 123 can be inserted into or pulled out of the insertion groove 110 e. In a state where the insertion rib 123 is inserted into the insertion groove 110e, the first clamping rib 124 can be clamped with the second clamping rib 112. On one hand, the two detachable connection modes of insertion and clamping enable the connection between the filter assembly 120 and the water return plate 110 to be more stable and firm. On the other hand, to a certain extent, it is convenient for the filter assembly 120 to be quickly and conveniently disassembled and assembled.
The specific structural shapes of the first clamping rib 124 and the second clamping rib 112 are not limited, in an embodiment, please refer to fig. 2 and fig. 6 to 10, the filtering apparatus 100 includes a bending rib 150 disposed on the housing 121, the bending rib 150 extends from the housing 121 to the top side and bends to one side away from the water returning plate 110, the first clamping rib 124 is a convex structure, the first clamping rib 124 is disposed on the top surface of the bending rib 150, the second clamping rib 112 is an open groove-shaped structure at the bottom side, the bending rib 150 elastically deforms to the bottom side, so that the first clamping rib 124 can be inserted into the second clamping rib 112 through the open bottom side of the second clamping rib 112. That is to say, first joint muscle 124 sets up in the top of housing 121, grafting muscle 123 sets up in the bottom of housing 121, under the state that grafting muscle 123 inserted inserting groove 110e, to the bottom side press bending muscle 150, bending muscle 150 takes place elastic deformation to the bottom side, first joint muscle 124 inserts in second joint muscle 112 through the open department in bottom side of second joint muscle 112, loosen bending muscle 150, bending muscle 150 provides the elastic force to the top side, so that first joint muscle 124 can support the internal surface of tight second joint muscle 112, make first joint muscle 124 and second joint muscle 112 joint.
The number of the first clamping ribs 124 and the second clamping ribs 112 is not limited, and in one embodiment, the number of the first clamping ribs 124 and the second clamping ribs 112 is one. In another embodiment, referring to fig. 2 and fig. 6 to fig. 10, the number of the first clamping ribs 124 and the number of the second clamping ribs 112 are both multiple, and the first clamping ribs 124 and the second clamping ribs 112 are arranged in a one-to-one correspondence manner. Illustratively, in one embodiment, the number of the first clamping ribs 124 and the number of the second clamping ribs 112 are two.
To facilitate the user's pressing on the bending ribs 150, in one embodiment, referring to fig. 9 and 10, the filter device 100 includes a non-slip strip 160 disposed on the top surface of the bending ribs 150. The anti-slip strip 160 can reinforce the friction of the top surface of the bending rib 150, thereby preventing the user's finger from slipping off when pressing the top surface of the bending rib 150.
The specific structure of the backflow prevention structure 130 is not limited, and for example, in an embodiment, please refer to fig. 2, fig. 3, fig. 5, and fig. 6, the backflow prevention structure 130 includes a plurality of backflow prevention units 131, and the backflow prevention units 131 are arranged in a staggered manner. The flow rate of the water from the inlet channel 1a is large, the flow rate is high, and the water from the inlet 110a can smoothly flow into the filter chamber 100a through the staggered gaps between the backflow prevention units 131. In the process that the flock in the filter cavity 100a flows back under the stirring and impact of water flow, the kinetic energy of the returned flock is generally low, that is, the moving speed of the returned flock is low, and the returned flock can enter the water inlet 110a only by avoiding the plurality of backflow prevention units 131, and in the process, the water flow from the water inlet 110a can flush the returned flock back into the filter cavity 100a, so that the backflow prevention units 131 can retain the flock in the filter cavity 100 a.
In an exemplary embodiment, referring to fig. 2, fig. 3, fig. 5 and fig. 6, the backflow prevention units 131 are arranged at intervals in a layer along the height direction of the filtering apparatus 100, the backflow prevention units 131 in the same layer are arranged at intervals, and two adjacent layers of backflow prevention units 131 are arranged in a staggered manner. The movement speed of the reflowed flocks is slow, and the multilayered backflow prevention unit 131 is difficult to avoid, so that the flock stopping capability is further improved.
In order to further improve the reliability of the collection of the lint, in one embodiment, referring to fig. 5, in a top-view projection of the filtering apparatus 100, a projection of the backflow prevention unit 131 at the upper layer can cover a gap between projections of two adjacent backflow prevention units 131 at the lower layer. In this way, the returned lint is further prevented from escaping from the excessive misalignment gap between the two adjacent layers of the backflow prevention units 131.
The specific structural shape of the backflow prevention unit 131 is not limited, and for example, in an embodiment, referring to fig. 5 and 6, the backflow prevention unit 131 includes two straight slope surfaces 1311 connected to each other, the two straight slope surfaces 1311 abut against each other to form a tip, the tip is disposed toward the water inlet 110a, and the straight slope surfaces 1311 extend toward a side away from the water inlet 110 a. That is, one end of the backflow prevention unit 131 in the length direction thereof is connected to a side of the water return plate 110 facing the filter assembly 120. In this way, it is convenient to prevent the backflow prevention unit 131 from contacting and rubbing the filter assembly 120 by controlling the length of the backflow prevention unit 131 to control the assembly gap between the backflow prevention unit 131 and the filter assembly 120. In the process that the water from the water inlet 110a moves to the bottom side, the water from the water inlet 110a contacts the tip of the backflow prevention unit 131 and moves to the bottom side rapidly under the diversion action of the straight slope 1311, so that the flock in the water from the water inlet channel 1a is prevented from winding on the straight slope 1311. A blocking space is formed between the two straight slope surfaces 1311, and in the process that the reflowing flocks under the impact of water waves move to the top side, the water waves are stopped by the blocking space, so that the reflowing flocks are prevented from reflowing to the water inlet 110 a.
In one embodiment, referring to fig. 3 and 6, the length of the backflow prevention unit 131 is gradually decreased from the bottom layer to the top layer. Since the backflow of the lint is less as it gets closer to the top layer, the backflow of the lint is mainly concentrated at the backflow preventing unit 131 of the bottom layer, and the distance between the backflow preventing unit 131 of the bottom layer and the inner surface of the opposite filter chamber 100a is small, thereby preventing the backflow of the lint from escaping through the gap between the backflow preventing unit 131 and the inner surface of the opposite filter chamber 100 a. The back-flowing shavings are very small at the top anti-backflow unit 131, the amount of water from the water inlet 110a is large, the gap between the top anti-backflow unit 131 and the inner surface of the opposite filter chamber 100a is large, and interference of the water flow from the water inlet 110a into the filter chamber 100a is avoided as much as possible under the condition of a certain shavings stopping capability.
The various embodiments/implementations provided herein may be combined with each other without contradiction.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
