However, the installation method of the filter screen structure in the related art is complex, for example, it is installed in the drain port by screwing, which increases the difficulty of disassembling and assembling the filter screen structure. SUMMARY
[0005] The technical problem solved by the utility model is that in the related art, a filter screen structure is arranged in the drain port to intercept the impurities passing through the drain port. However, the installation method of the filter screen structure in the related art is complex, for example, it is installed in the drain port by screwing, which increases the difficulty of disassembling and assembling the filter screen structure.

In addition, the third connecting piece can also be a third magnet composed of a magnetic material, and the magnetism of the third magnet and the first magnet is of opposite nature to realize the effect of mutual attraction. In combination with the mutual cooperation relationship of the drainage hose, the drain port and the filter screen structure, the first magnet is located between the second magnet and the third magnet. It needs to be emphasized that the magnetic attraction force formed between the first magnet and the second magnet is greater than the mutual repulsion force formed between the second magnet and the third magnet, so as to ensure that the filter screen structure can be smoothly limited in the drain port.
[0012] In one example of the utility model, the connection mode between the drain port and the drainage hose includes clamping.
[0013] Compared with the prior art, the technical effects reached by adopting the technical scheme are that the stability of the drainage hose installed into the drain port is improved through the combined cooperation mode of magnetic attraction and clamping.
[0014] In one example of the utility model, the connection mode between the drain port and the drainage hose includes screwing; when the drainage hose is screwed to the first relative position relative to the drain port, the first connecting piece and the third connecting piece are oppositely arranged to enable the drainage hose and the drain port to be magnetically attracted and cooperated; when the drainage hose is rotated to the second relative position relative to the drain port from the first relative position, the first connecting piece and the third connecting piece are arranged in a staggered manner.

Specifically, the arrangement positions of the clamping protrusion and the first connecting piece on the drainage port can be arranged in a stacked manner, and correspondingly, the arrangement positions of the clamping groove and the third connecting piece on the drainage hose can also be arranged in a stacked manner. Therefore, the clamping tightness between the clamping protrusion and the clamping groove is further improved by the magnetic attraction force, the risk of the clamping protrusion being detached from the clamping groove under unexpected circumstances is reduced, and the reliability of the drainage hose installed on the drainage port is improved.

If the filter screen structure is arranged in the second drainage cavity, because the diameter is smaller, the impurities are more likely to be blocked in the second drainage cavity, so that the user needs to disassemble and clean the filter screen structure more frequently, which is inconvenient for the user and affects the user experience. In addition, by using the diameter of the first drainage cavity and the second drainage cavity, the situation that the filter screen structure accidentally enters the second drainage cavity is effectively avoided.

In combination with the cooperation relationship of the drain hose 30, the drain port 11 and the filter screen structure 20, the first magnet is located between the second magnet and the third magnet.
