Abstract

The utility model provides an odour discharging device of a toilet bowl, which belongs to the technology of negative-pressure odour suction and water sealing. When a user goes to a toilet, a magnetic valve is opened to discharge storage water in a water sealing tank, the water sealing is removed to form a passage, meanwhile, an exhaust fan is started to suck the odour in the toilet bowl into a water box through an annular water flushing passage and an overflow pipe, the odour is pressed into the water sealing tank and a gas guiding pipe through the exhaust fan and enters the S-shaped bend of the toilet bowl until a drain pipe; the user flushes water after going the toilet, a power supply is switched off at the same time, a water discharging hole of the water sealing tank is sealed by the magnetic valve, water is fully filled in the sealing tank through a water supply pipe of a water inlet piece, the redundant water flows into the S-shaped bend of the toilet bowl to form the water sealing, and the odour in the drain pipe can not return the toilet . The odour discharging device not only can be directly arranged on the toilet bowl when the toilet bowl is produced, can also be reconfigured on a common toilet bowl, and can realize the sanitation environment without odour when the user goes to the toilet, and the function of the toilet bowl can not be influenced.

Description

Smelly device is arranged in the water seal of closet negative pressure

Affiliated technical field

The utility model relates to water closet and arranges smelly device, is that smelly device is arranged in the water seal of a kind of closet negative pressure.

Background technology

For a long time, people always go to toilet smoked as to be difficult to stand by own excremental foul smell, wish to have a kind of closet that can get rid of this foul smell, known today a kind of be the deodorizing of coverage method, utilization be chemical mode; Another kind is a degassing method, utilization to be the exhaust electric fan discharge the foul smell of washroom.More than two kinds all can't resolve and discharge the foul smell that the user smells.Another is that the foul smell in the closet is directly entered the sewer of water closet by bleeding, but crucial be the biogas that can not the guarantee sewer washroom that do not backflow, cause more serious pollution, influence the washing capacity of water closet simultaneously.

Summary of the invention

Arrange smelly problem for overcoming existing closet, the utility model provides the water seal of a kind of closet negative pressure to arrange smelly device, and this device can not only be got rid of the closet foul smell, and blocking-up biogas backflow indoor may, can on various water closets, transform simultaneously and install and use, and not influence the washing capacity of water closet.

The technical scheme that the utility model adopted is: the negative pressure water seal is housed in tank for excrement pan arranges smelly device, this device has an electronic exhaust electric fan, the exhaust electric fan is connecting anti-siphon water sealed tank, an electromagnetic valve is arranged in the water sealed tank, water sealed tank is connected to closet stench trap leading portion by extract duct, and the filling pipe of water tank water intake parts is connected to water sealed tank toward the water seal moisturizing.When going to toilet, opening power, the exhaust electric fan is toward the water sealed tank exhaust, in the water tank because the negative pressure appearance of bleeding and producing, atmosphere enters water tank by closet annular bath road and cistern fittings bleed off pipe, electromagnetic valve is opened the water in the water sealed tank is discharged from outfall simultaneously, and it is straight-through that water sealed tank and extract duct are formed, and the foul smell in the closet waltzs through the closet stench trap with gas flow and enters sewer.

When having gone to toilet bath, powered-down exhaust electric fan quits work simultaneously, closed electromagnetic valve hermetically sealed can outfall, this moment the water tank water intake opening of valves, water flows into hermetically sealed can from filling pipe, deposits in and forms water seal in the water sealed tank, the blocking-up circulation of air, unnecessary water will flow directly into stench trap water closet will be formed water seal, so both guarantee that the biogas of sewer can not enter water tank, the function when not influencing the water closet bath again.

The beneficial effects of the utility model are that this device can be reequiped on common water closet, realizes going to toilet not smelly hygienic conditions.

Description of drawings

Fig. 1 is a constructional drawing of the present utility model.

Fig. 2 and Fig. 3 are working state figures of the present utility model.

1. water sealed tanks among Fig. 1,2. aqua storage tank, 3. outfall, 4. electromagnetic valve, 5. wireway, 6. moisturizing interface, 7. exhaust electric fan, 8. water sealed tank cover plate, 9. exhaust opening, 10. stench trap, 11. pipelines, 12. filling pipes, 13. annular bath roads, 14. bleed off pipes, 15. water intaking valves.

The specific embodiment

Among Fig. 1, this device is installed in tank for excrement pan, it is characterized in that: aqua storage tank (2) is arranged in the water sealed tank (1), outfall (3) is arranged at aqua storage tank (2) bottom, outfall (3) is controlled by electromagnetic valve (4), wireway (5) is arranged in the aqua storage tank (2), moisturizing interface (6) and exhaust electric fan (7) are arranged on the wireway (5), wireway (5) outer wall has water sealed tank cover plate (8) that water sealed tank (1) is sealed, exhaust opening (9) is arranged at water sealed tank (1) bottom, all gapped between water sealed tank (1) and aqua storage tank (2) and the wireway (5), its bottom is also all gapped respectively, the formation passage is channel flow so that gas is postponed, aqua storage tank (2) highly is not less than the water seal height of closet stench trap (10), outfall (3) has pipeline (11) to be connected to closet stench trap (10), and cistern fittings filling pipe (12) is connected to the moisturizing interface (6) on the wireway (5), and exhaust electric fan (7) is in parallel with the circuit of electromagnetic valve (4).

Among Fig. 2, during use, electric power starting, electromagnetic valve (4) is opened, the water of water seal flows out water sealed tank (1) rapidly by outfall (3) in the aqua storage tank (2), flow into closet stench trap (10) along pipeline (11), wireway (5) is eliminated to form with the water seal of aqua storage tank (2) and is led directly to, at this moment, exhaust electric fan (7) is worked simultaneously, and water tank produces negative pressure appearance, atmosphere enters water tank by the bleed off pipe (14) of closet annular bath road (13) and cistern fittings, enter wireway (5) through exhaust electric fan (7), aqua storage tank (2), water sealed tank (1) is again by exhaust opening (9), pipeline (11) enters sewer.

Among Fig. 3, when dashing just, the while powered-down, exhaust electric fan (7) quits work, electromagnetic valve (4) cuts out outfall (3) simultaneously, cistern fittings water intaking valve (15) is opened to water tank water intake, to cistern fittings filling pipe (12) moisturizing, water flow in the aqua storage tank (2), fills with the formation water seal simultaneously, unnecessary water in the aqua storage tank (2), overflow aqua storage tank (2), flow into water sealed tank (1), flow into the closet stench trap (10) along pipeline (11) from outfall (3), be closet stench trap (10) moisturizing, form water seal.
