however, in other embodiments, one end of the rotating shaft 322 is fixed to the water cup 100, and the cylindrical support body 321 and the rotating shaft 322 rotate relatively to drive the filter screen to move relative to the water in the water cup 100, and of course, it is also possible that the cylindrical support body 321 and the rotating shaft 322 rotate relatively, and one end of the rotating shaft 322 is connected to the water cup 100.
Further, in an embodiment, the other end of the rotating shaft 322 is connected to the spray cap 200, the rotating shaft 322 is provided with a water channel 322a penetrating along the axis direction of the rotating shaft 322, one end of the water channel 322a is communicated with the water supply device 400, and the other end is communicated with the water inlet 200a, it can be understood that the water provided by the water supply device 400 is conveyed into the spray cap 200 through the water channel 322a, the additional arrangement of a pipeline is avoided to be communicated with the spray cap 200 and the water supply device 400, the miniaturization of the filtering system is facilitated, the rotating shaft 322 not only enables the columnar bracket 320 to rotate, but also supplies water to the spray cap 200, the functions of the rotating shaft 322 are greatly enriched, it is worth mentioning that the water supply device 400 comprises a washing pump 410 and a spray pipe 420, the bottom of the backwater cavity 100a is provided with a water receiving hole, one end of the spray pipe 420 is communicated with the washing pump 410, and the other end of the water receiving hole is also communicated with one end of the rotating shaft 322 close to the water receiving hole, so that the water supply device 400 supplies water to the spray cap 200;
of course, in other embodiments, if it is considered that the rotation shaft 322 needs to maintain high structural strength, a pipeline may be added to connect the water supply device 400 and the shower cover 200.
The connection manner between the rotating shaft 322 and the columnar support body 321 is various, in one embodiment, the rotating shaft 322 and the columnar support body 321 are integrally formed, so that the assembly process of the rotating shaft 322 and the support body is reduced, for example, the assembly process can be performed by injection molding and the like; however, the present design is not limited thereto, and in other embodiments, in consideration of reducing the manufacturing difficulty of the columnar support 320, in other embodiments, the columnar support body 321 and the rotation shaft 322 may be provided as separate members and then connected together by means of assembly, for example, the columnar support body 321 is provided with a fixing hole for interference fit of the rotation shaft 322 so that the rotation shaft 322 is tightly fitted with the columnar support body 321; alternatively, the columnar bracket body 321 and the rotating shaft 322 may be provided with mutually matched engagement structures, such as a buckle part and the like; as another example, the columnar bracket body 321 and the rotation shaft 322 are connected by means of screws or the like. Of course, in still another embodiment, the columnar bracket body 321 may be further connected to the rotation shaft 322 by welding to increase the structural strength of the columnar bracket 320, and of course, from the viewpoint of manufacturing cost of the columnar bracket 320, the columnar bracket body 321 and the rotation shaft 322 may be further connected by bonding.
Specifically, in one embodiment, the columnar support 320 includes an upper ring frame, a lower ring frame parallel to the upper ring frame, and a plurality of support rods connecting the upper ring frame and the lower ring frame, the plurality of support rods are arranged at intervals along the axial direction of the upper ring frame, and the plurality of support rods are parallel to each other. Of course, further, in an embodiment, the upper ring frame and/or the lower ring frame are/is provided with a connecting portion, and the connecting portion is provided with a fixing hole.
It can be appreciated that, in addition to the filtering structure, the spray cap 200 plays a very important role in the filtering system, and the spray cap 200 drops the residues attached to the cylindrical filter screen 310, so that the frequency of cleaning the cylindrical filter screen 310 is reduced, and the user experience is improved; the spray cap 200 has a water inlet 200a and a water outlet 200b connected to the water inlet 200a, in an embodiment, the spray cap 200 has a rotation axis, a vector of the water outlet 200b in a direction has a component tangential to a circumferential direction of the rotation axis, specifically, the spray cap 200 is connected to a rotation shaft 322 of the columnar support 320, the rotation axis is an axis of the rotation shaft 322, a water velocity of water sprayed from the water outlet 200b has a component speed perpendicular to the rotation axis so as to drive the rotation shaft 322 to rotate, thereby providing a power for relatively moving the cylindrical filter screen 310 arranged on the columnar support body 321 with water in the water cup 100, so that residues on the cylindrical filter screen 310 can be moved by water in the water cup 100, thereby reducing residues attached to the cylindrical filter screen 310, and it can be understood that the spray cap 200, the columnar support 320 and the cylindrical filter screen 310 rotate as a whole, the water sprayed from the spray cap 200 can also pass through a mesh opening on the columnar support 320 to the water cup 100 to reduce the cost of water cup 100 to be attached to a water cup 100 to a water return cavity of the dishwasher, and reduce the cost of water return to the water cup 100 a;
of course, in other embodiments, the direction of the water outlet 200b is parallel to the rotation axis and faces the filter cavity defined by the cylindrical filter screen 310, so that the water flow speed in the filter cavity can be increased, so that the water in the filter cavity is converted to a turbulent state, and under the impact of the water flow in the turbulent state, the residues on the net threads attached to the cylindrical filter screen 310 are washed off by the water flow, so as to separate from the cylindrical filter screen 310, thereby reducing the frequency of cleaning the filter screen by a user, and greatly improving the user experience.
It should be noted that in other embodiments, a motor may be used to provide a power source for the shower cover 200, the motor is connected to the shower cover 200 in a driving manner, and the column-shaped support 320 may be provided with another motor.

Further, in an embodiment, the side wall of the first water guiding groove opposite to the communication opening 200c shields a part of the communication opening 200c, specifically, the water flow in the spray cap 200 flows out from the opening defined by the communication opening 200c and the water outlet 200b, so that on one hand, the speed of the sprayed water flow has a component perpendicular to the rotation axis, and on the other hand, the spraying range of the spray cap 200 is increased, so that more residues attached to the cylindrical filter 310 are sprayed, and the residues are further promoted to be separated from the cylindrical filter 310. Of course, in other embodiments, the side wall of the first water guiding groove opposite to the communication port 200c completely shields the communication port 200c, so as to ensure that the shower cover 200 has a larger rotation speed.
In one embodiment, the water outlet holes 200b are provided in a plurality, and the plurality of water outlet holes 200b are beneficial to increase the cleaning range, so that more residues attached to the cylindrical filter 310 are sprayed, and the residues are further separated from the cylindrical filter 310. Specifically, the resultant vector of the directions of the plurality of water outlet holes 200b has a component perpendicular to the rotation axis, and of course, in other embodiments, the directions of the plurality of water outlet holes 200b are parallel to the rotation axis.
Further, the shower cover 200 further has a water storage chamber 200d communicating the water inlet 200a and the water outlet 200b, specifically, water from the water inlet 200a can fill the water storage chamber 200d, water in the water storage chamber 200d is sprayed out from the water outlet 200b, the water storage chamber 200d provides a water storage space, it is beneficial to ensure that water flow from the water outlet 200b can be sprayed out in a stranded manner, and when the shower cover 200 is started next time, water can be sprayed out from the water outlet 200b immediately due to water in the water storage chamber 200 d.
