Abstract

The utility model relates to a toilet ventilator which is composed of a ventilation fan, a ventilation fan case, a ball float arranged on a top opening of an overflow tube in a water tank and an exhaust tube. The ventilation fan case is sealed except an air inlet, a shutter and an exhaust vent, one end of the exhaust tube is connected with the air inlet, and the other end is connected with a toilet water supply tube. The ventilation fan and the case are arranged on the toilet wall together when using, the exhaust vent is coincided to an air vent, users can open the ventilation fan when using, so the ball float can block the top opening of the overflow tube, and the smelly gas in the urinal can be extracted. When the shutter is opened, the smelly air in the toilet can be eliminated, so the utility model has the advantages of simple structure, low cost and convenient operation.

Description

Toilet ventilator

The utility model relates to a kind of lavatory compound ventilation air-changing device.

Current, people live in the unit building, employed lavatory, and the area that often can not directly communicate or communicate with the external world is very few, and is connected nearerly with the room because of it, and foul smell often be difficult for to be got rid of in the lavatory, and the people is often breathed in bad atmosphere, hinders health.Though the lavatory that has is provided with exhaust apparatus, just get rid of indoor foul smell mostly, when people separated just, foul smell can not in time be got rid of in the urinal, and the then complex structure that has uses inconvenience.

The purpose of this utility model is that a kind of lavatory compound ventilation air-changing device will be provided, and it is simple in structure, and is easy to use, both can get rid of indoor foul smell, in the time of also can in time getting rid of people and separate just, and the foul smell that in chamber pot, produces.

This practical purpose be achieved in that this compound ventilation air-changing device by ventilation fan, ventilation fan outer cover, be positioned at ball float and the exhaust tube of water tank overflow pipe on suitable for reading and constituted, the ventilation fan outer cover is except that leaving air inlet, valve and steam vent, all the other all seal, exhaust tube one end connects air inlet, and the other end is connected with the chamber pot feed pipe.During use, ventilation fan is installed on the wall of lavatory together with outer cover, exhaust outlet is aimed at ventilating opening, when separating just, opens ventilation fan, and it is suitable for reading that ball float blocks overflow pipe, and foul smell promptly is drawn out of in the urinal; When valve is opened, can get rid of indoor foul smell.

The utility model has following advantage:

1. one-object-many-purposes, can in time get rid of foul smell in the lavatory completely: because of opening the valve on the ventilation fan outer cover, can get rid of the indoor foul smell in lavatory, valve is closed, when people separate just, can with in the chamber pot as yet not the foul smell before indoor distributing in time discharge; Because by the negative pressure that ventilation fan produced, much smaller than atmospheric pressure, so, also can not influence the bath of urinal feed pipe in the lavatory even when starting ventilation fan.

2. be skillfully constructed, simple in structure, cost is low: the utility model has utilized chamber pot existing osculum all around cleverly, as aspirating hole, utilize existing feed pipe to link to each other with exhaust tube, and only in time block automatically with ball float water service pipe in the water tank is suitable for reading, make into sealing, thereby reach the purpose of sealing when separating just, so needn't adorn a set of equipment in addition, thereby simplify the structure, reduce cost, promote the use of easily.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is the utility model general structure schematic diagram.

Fig. 2 is overflow pipe 17, mouth of pipe fence 15 and upper floating ball 4 position views thereof in the water tank 16.

Fig. 3 is the ventilation fan schematic diagram that has outer cover.

Fig. 4 is the steam vent schematic diagram.

Fig. 5 is whole valve 8 schematic diagrames.

Fig. 6 is valve 6 exploded view.

Fig. 7 is valve 2 assembling back schematic diagrames.

With reference to Fig. 1～7, this lavatory uses compound ventilation air-changing device by ventilation fan, ventilation fan outer cover, ball float and exhaust tube constitute, ventilation fan outer cover 1 with ventilation fan except that leaving air inlet 3, valve 2 and steam vent 7, all the other all seal, air inlet 3 is connected with exhaust tube 14, and the other end of exhaust tube 14 is connected with the feed pipe 5 of chamber pot 6; Ball float 4 is positioned on the mouth of pipe of water tank 16 overflow pipes 17, is with the fence 15 that is fixed on the mouth of pipe around ball float 4, and ball float 4 can only move up and down in fence.Valve 2 on the ventilation fan outer cover, be one with the akin structure of electric light pullswitch, this valve 2 is made of the fixed disk 9 that vertical rod 18 is housed, rotating disk 10, pushing piece 11, spring 12 and nut 13; Fixed disk is fixed on the cover body 1 with screw, fixed disk 9, rotating disk 10 are equipped with 90 ° the two corresponding sector notch of being separated by, rotating disk 10, pushing piece 11, spring 12 overlap and are enclosed within the vertical rod 18, the stiff end of spring 12 inserts in the vertical rod 18, the other end is stuck on the pushing piece 11, the edge of indentation, there matches on pushing piece 11 subsurface two corresponding raised lines and the rotating disk 10, and rotating disk 10 can rotate with the rotation of pushing piece 11, and nut 13 is enclosed within the vertical rod 18 each component locations relative fixed.In addition, the valve on this ventilation fan outer cover can make whole valve 8, is installed on the annulus that matches with it with hinge, and this annulus is fixed on the outer cover 1.For avoiding foul smell to pour in down a chimney, steam vent 7 is provided with unidirectional opening the door, and is washed open by air-flow during exhaust, not the time spent, utilizes gravity to close automatically.

During use, close the valve on the ventilation fan outer cover, the people is sitting on the chamber pot, starts ventilation fan, because of the ball float 4 suitable for reading of overflow pipe in the water tank 16 is blocked suitable for reading by suction, pipeline is airtight, foul smell can be sucked out via the osculum around the bucket wall in the chamber pot, when need are discharged the indoor foul smell in lavatory, valve is opened, then indoor foul smell can be discharged by steam vent through valve.

When using valve, then spur pushing piece 11, drive rotating disk 10 rotations, two sector notch on the rotating disk 10 and two sector notch on the fixed disk 9 are coincided, so valve is opened, pushing piece 11 sets back again under spring 12 effect, as when closing, spur pushing piece 11 again, then rotating disk 10 continues rotation again, the breach on the fixed disk is blocked, thereby reach the purpose of valve folding.
