In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a floor drain, includes the panel, sets up filter, the water filtering chamber of fixed connection in the panel intermediate position, connects the water seal cup of water filtering chamber lower part and can dismantle with the water seal cup and be connected and be restricted the water seal inner core at water seal cup middle part, is provided with the drainage slotted hole of grid form on the filter, and open on the well upper portion of water seal cup has the delivery port, the drainage intracavity is provided with a shell structure's filter equipment, filter equipment comprises the last filter screen of hemisphere cavity structure and the lower filter screen of hemisphere cavity structure, it has the slotted hole A who distributes along the symmetry axis direction to go up to open on the filter screen, it has the slotted hole B that distributes along the annular outer wall direction of cross section to open on the filter screen down.

The lower end of the water filtering cavity is provided with an inner step, and the peripheral side of the maximum outer diameter of the filtering device is provided with an outer step in clearance fit with the inner step.

Wherein, go up the filter screen with the filter screen is dismantled and is connected down.

Wherein, the middle part of the upper end surface of the upper filter screen is provided with a carrying handle.

The slotted hole A and the slotted hole B are strip-shaped slotted holes.

Wherein, the bottom of the water seal cup body is of a hemispheroid cavity structure.

The invention has the advantages that: the internal component easy dismounting, it is convenient to wash, goes up the filter equipment that upper and lower wire side vertically and horizontally staggered that filter screen and lower filter screen are constituteed, both has enough big water flow cross-section in order to ensure drainage speed, has stronger ability in order to prevent to block up longer hair again, and is very practical.

Detailed Description

As shown in fig. 1 and 2, the floor drain comprises a panel 1, a filter plate 2 arranged in the middle of the panel 1, a water filtering chamber 3 fixedly connected to the lower part of the panel 1, a water sealing cup body 4 connected to the lower part of the water filtering chamber 3, and a water sealing inner core 5 detachably connected to the water sealing cup body 4 and limited in the middle of the water sealing cup body 4, wherein the water sealing inner core 5 is placed on an inner boss 42 of the water sealing cup body 4 to facilitate placement and removal. The filter plate 2 is provided with grid-shaped water filtering slot holes for filtering sundries such as hair for the first layer, and the middle-upper position of the water sealing cup body 4 is provided with water outlets 41 which are uniformly distributed along the whole body.

And, there is a body structural filter equipment 6 in the drainage lumen 3, it is made up of hemispherical cavity structural upper filter screen 61 and hemispherical cavity structural lower filter screen 62, especially, there are slotted holes A611 distributed along its axis of symmetry direction on the upper filter screen 61, there are slotted holes B621 distributed along the annular outer wall direction of its cross section on the lower filter screen 62, and all slotted holes, like this, the upper filter screen 61 forms the filter structure with cross interweave structure with vertical gradient with the lower filter screen 62, have already strengthened the ability to filter debris such as the hair, etc., do not influence the drainage speed.

The lower end of the water filtering cavity 3 is provided with an inner step 31, the peripheral side of the maximum outer diameter position of the filtering device 6 is provided with an outer step 63 which is in clearance fit with the inner step 31, and the filtering device 6 is placed on the inner step 31 in the water filtering cavity 3 when in use.

In order to facilitate the cleaning of the inner and outer layers of the filtering device 6, the upper filter screen 61 and the lower filter screen 62 are detachably connected, and the embodiment adopts threaded connection. In addition, a handle 612 is arranged in the middle of the upper end surface of the upper filter screen 61, so that the filter device 6 can be conveniently taken out of the water filtering cavity 3.

The bottom of the water seal cup body 4 is of a hemispherical cavity structure, so that sundries with high density, such as silt, can be effectively prevented from being accumulated at the bottom, and the inside cleaning is also facilitated.

When the filter is used, water flow flows into the water filtering cavity 3 and then is generally in a vortex flow direction, firstly passes through the upper filter screen 61 of the hemispherical cavity structure in an outward convex state, impurities such as hair and the like with a larger volume are easily blocked at the lower side of the upper filter screen 61 due to the opening shape and the opening direction of the slotted hole A611, then the water flow flows through the lower filter screen 62 of the hemispherical cavity structure in an inward concave state, and the impurities such as hair and the like passing through the upper filter screen 61 are intercepted and filtered again at different angles, so that the filtering capacity of the impurities with a larger volume is greatly improved, and the filter structure in vertical gradient distribution has a sufficiently large water flow section, has small resistance to the water flow, can ensure the water flow speed, is convenient to disassemble and assemble internal components, is beneficial to overall cleaning, and is.
