Abstract
The invention discloses a backflow preventing urinal, which comprises a urinal body, wherein the urinal body is connected with a water inlet pipeline and a water outlet pipeline, the water inlet pipeline is provided with a press switch and a valve core, the press switch is used for controlling water drainage, the water outlet end of the water inlet pipeline is provided with a spray head, a V-shaped water outlet is arranged in the spray head, and is provided with a spiral water guide sheet, the water inlet end of the water inlet pipeline is provided with a backflow preventing device, the backflow preventing device comprises a nut and a pipeline connecting piece, the side part of the nut is provided with a valve core hole, and a backflow preventing valve core is arranged in the valve core hole. The urinal has the advantages that the water drainage range is expanded by the V-shaped water outlet of the spray head, and the water is sprayed out in a fan shape; by arranging the spiral water guide sheet, the water direction is cut during water drainage, so the water drainage intensity is improved; the structure is simple, and the pollution to a drinking water pipeline caused by the residual water in the urinal flowing back into a water supply source is prevented.
Description
Technical field
the present invention relates to the urinating bucket field of sanitary bath equipment, particularly relate to a kind of backflow proof urinating bucket preventing the remaining water in urinating bucket to be back to water source and polluted source.
Background technology
at present, at use urinating bucket after bath terminates, Yu Shui can be left in its inside, if emptying not in time, there is rotten or breed bacteria in the Yu Shuihui after a period of time in urinating bucket, when supply channel produces negative pressure condition; the Yu Shuihui in urinating bucket flows backward in watering; rotten water may flow in drinking water pipeline, causes drinking water contaminated, therefore can there is unhygienic, unsound hidden danger.
in addition, the urinating bucket of prior art is depressed at normal water, and the water flow of common urinating bucket can wash away or rinse the effect of urinating bucket substantially; But when hydraulic pressure is on the low side, often cause the speed of urinating bucket water outlet too low little with water outlet, this dynamics just causing current flushing is little, and can cause a large amount of invalid water, wastes water resource; And even if when hydraulic pressure is normal, because the scope of the particularity of Male urine and urine is wide, in the position near urinating bucket sidepiece, the urinating bucket of prior art is more difficult flushing.When flow velocity is too low, often waste water is extremely serious, and the effect of washing away urinating bucket is not obvious, also there is peculiar smell after sometimes washing away, and reduces the rank of field of employment and causes the unhygienic of environment.
Summary of the invention
the present invention in order to solve the above problems, provide a kind of prevent the remaining water of urinating bucket to be back to drinking water pipeline and polluted source to reach the backflow proof urinating bucket of water supply security health.
the technical solution adopted for the present invention to solve the technical problems is: a kind of backflow proof urinating bucket, comprise urine head main body; urine head main body is connected with inlet channel and drainage pipe; inlet channel be provided with control water outlet by compressing switch and spool; the water side of described inlet channel is provided with shower nozzle; be provided with V-type delivery port in shower nozzle, and delivery port is provided with spiral ater guide piece; The water inlet end of described inlet channel is provided with back-flow preventer, and back-flow preventer comprises nut and conduit coupling, and the sidepiece of nut is provided with spool bore, is provided with backflow proof spool in spool bore.The V-type delivery port of shower nozzle the expanded range of water outlet, namely in fan-shaped ejection, and can add helical form ater guide piece, cuts the direction of water, strengthen the dynamics of water outlet when water outlet.
further, described backflow proof spool is stop valve, and one end of backflow proof spool is provided with 6 reinforcing ribs.
the invention has the beneficial effects as follows: a back-flow preventer is set before the inlet channel of urinating bucket; When current are from the water inlet end water side that inflow internal diameter is larger at a high speed that internal diameter is less, water flow jet makes to form negative pressure in the cavity of backflow proof spool, when after closedown watering; the remaining water in urinating bucket flows into anti-reflux valve in-core because the pressure of anti-reflux valve in-core is less; the remaining water in urinating bucket can be prevented to be back to watering, the ducted water of polluted drinking water.

Detailed description of the invention
embodiment 1
a kind of backflow proof urinating bucket described by the present embodiment 1, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, comprise urine head main body 7; urine head main body is connected with inlet channel 8 and drainage pipe; inlet channel be provided with control water outlet by 9 and the spool of compressing switch; the water side of described inlet channel is provided with shower nozzle 10, is provided with V-type delivery port 11 in shower nozzle, and delivery port is provided with spiral ater guide piece 12; The water inlet end of described inlet channel is provided with back-flow preventer 1, and back-flow preventer comprises nut 2 and conduit coupling 3, and the sidepiece of nut is provided with spool bore 4, is provided with backflow proof spool 5 in spool bore.The V-type delivery port of shower nozzle the expanded range of water outlet, namely in fan-shaped ejection, and can add helical form ater guide piece, cuts the direction of water, strengthen the dynamics of water outlet when water outlet.
further, described backflow proof spool is stop valve, and one end of backflow proof spool is provided with 6 reinforcing ribs 6.
the above is only preferred embodiment of the present invention, not does any pro forma restriction to structure of the present invention.Every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical scheme of the present invention.
