Concrete structure of the present invention is provided by following accompanying drawing, summary of the invention and embodiment:

Fig. 1 is the manually anti-blocking smelly floor drain sectional view that overflows of the valve of switching of band.

Fig. 2 is the anti-blocking smelly floor drain sectional view that overflows that valve automatic and that manually open and close is arranged, double as specification digest accompanying drawing.

Fig. 3 is with the adjustable for height structure sectional view of going up retaining lifting core bar of living on the core bar.

Fig. 4 is the structure sectional view that keeps off the lifting core bar up and down of using the similar side tooth-like clutch of lower retaining surface shape.Go up retaining among the figure and do not cut open, double dot dash line is the outline position before the retaining right part cuts open down.

The object of the present invention is achieved like this: in conjunction with Fig. 1 or Fig. 2, and this floor drain heart, its feature is worn funnel (11) under its grate (2), grate and funnel form the grate bucket, and ［ filler tube section is changeable, can be condensed to zero, weak point person's pipe section is in the charge for remittance chamber, and elder's pipe section puts in the drainpipe. The grate bucket can removably be assemblied in corresponding floor drain charge for remittance cavity (19) top, to form floor drain, ［ assembling comprises that the two indirect installation of passing through other parts, material connects, among the figure by each other with internal thread (10), external screw thread (8) screw fixing, should screw closely or tightly, ］ make through floor drain and must pass through funnel (11) to the fluid of dirty or upruss; Grate (2) is being to run through core bar (4) in hub bore (12) and the funnel end opening (14) with like hub section (20) like hub section through hole; Core bar top namely keeps off (5 with the stop part that stops core bar to take off from the hub bore decline, or nut 6), the bottom is connected with spool (15), and can in hub bore, move up and down flexibly and comfortably, move up can be with movable valve plug to close to be combined in funnel end opening (14) upper form to close make the current cut-off, spool disengaging funnel end opening is opened current intake-discharge pipe (16) when moving down; And have following any one or two kinds of devices manually and in the automatic switch device: one, stirring that this opening and closing device can shut spool (15) ［ is exactly to close spool, make forward and reverse hydraulic pressure all push away not open spool stopping forward and reverse current, be called for short fluid stopping ］, the spool that shuts opened or cancelled the manual opening and closing device that shuts; Two, the suffered hydraulic pressure of spool make a concerted effort downwards and spool can be pushed open when reaching appropriate value, spool is closed during less than a certain appropriate value the variation in water pressure of utilizing opens and closes the automatic switch device of spool. The closed position of spool is I among the figure, the open position II. The old place leakage heart is the grate with automatic shutter or the manual valve that opens and closes. So the floor drain with this floor drain heart removably assemblies floor drain with above-mentioned corresponding charge for remittance cavity (19) by above-mentioned requirements by the floor drain heart by its grate bucket, make through floor drain and must pass through funnel to the fluid of dirty or upruss.

After the water of process floor drain discharging passes through grate, funnel successively, flow into charge for remittance chamber (18) or do not flow into the charge for remittance chamber, enter the drainpipe (16) that is connected with floor drain and drain.

Below in conjunction with embodiment the present invention is further described: below grate, protrude out like hub portion (20), its hub bore (12) is better simply through hole, can be threaded, as Fig. 1, also hub bore can be made bottom band step (13), more than enlarge, topmost is replaced by the threaded centre bore of removably fixing (for example threaded engagement is fixed) heart stopple (22) thereon, as Fig. 2, be called retaining (3) down like what can contact with last retaining in the hub portion in order to block part or the part that retaining falls, last retaining and following the retaining, the two contacts at work, its contact surface is called upper retaining surface, lower retaining surface is as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.

Manual opening and closing device all is to use hand operation more than grate, can be by down one of array structure lifting core bar and spool with open and close valve:

1, utilization promotes core bar to put down promptly in core bar (4) adjustable for height height adjusting of going up retaining upward of living in and moves up and down, and for example upward retaining (5) is the just nutting that fits on the core bar upper external thread, transfers this height when turning, following retaining is replaced by heart stopple (22), as Fig. 3;

Or 2, utilization drives retaining and core bar moves up and down regulating like the height of adjustable for height retaining down of living in the hub portion, for example retaining is the just stubborn hollow screw (3) that matches with the hub bore upper internal threaded down, transfer this height when turning, the mandrel segment of this hollow screw is empty, be the through hole that is used to run through core bar top, as Fig. 1, Fig. 2;

Or 3, upper and lower block face shape is the profile of tooth male and fomale(M﹠F) of similar side tooth-like clutch ［ for example beveled side tooth-like clutch ］, utilizes and turns retaining, makes retaining and (3) clutch of following retaining, moves up and down to drive core bar, the lug boss of heart stopple is for keeping off down, as shown in Figure 4.

This has just realized at any time valve being closed dead or opening or cancel and close dead purpose by different needs.

Described automatic switch device relies on any one group or two stack features in following first, second two stack features, makes spool in the making a concerted effort downwards and spool can be pushed open when reaching appropriate value of suffered hydraulic pressure, and spool is closed during less than certain appropriate value:

First, spool moving part (6) and grate bucket are equipped with spring (7) between quiet (13), and the elastic force promotion spool moving part by spring makes spool close to funnel end opening shangguan.For example in hub bore, be furnished with nut (6) on the external screw thread of core bar, borrow the elastic force of the compression spring (7) on the base frame rank, hole (13) to promote nut, spool is closed, as shown in Figure 2 to shangguan.

All include ferromagnetics part (6,21) in the second, quiet of spool moving part and grate bucket, and have at least a side with the ferromagnetics part be the permanent magnet (21) that can attract the other side, attract magnetic force by it, spool is closed to funnel end opening shangguan.For example heart stopple is that permanent magnet (21) is equipped with at permanent magnet or heart stopple place, and the material of nut (6) is a ferromagnetics, borrows the attraction magnetic attraction nut of the two, spool is closed, as shown in Figure 2 to funnel end opening shangguan.

So spool is closed at ordinary times, opens automatically in the suitable moment of need draining.Here, move up and down in the process at spool, the part that directly indirectly connects and move up and down with spool with spool, for example spool, core bar, nut, last retaining all are the spool moving parts, directly indirectly connect with the grate bucket and keep relative static part with the grate bucket, for example the grate bucket, like hub portion, heart stopple, retaining, magnet, charge for remittance cavity all are quiet of grate buckets down.
