Description

The automatic deodorizing toilet cover of low level cistern

The utility model relates to the automatic deodorizing toilet cover of a kind of low level cistern.

When using sitting toilet, dirty gas is diffused into indoor, and contaminated air has increased pathogen transmission scope and chance, and the infringement people's is healthy.Existing toilet cover, exhaust motor are positioned at the gas exhaust piping end, cause the suction deficiency because pipeline is long, and the motor and the pipeline of engine body exterior have increased difficulty to installation, and be dangerous, not attractive in appearance.Existing toilet cover does not have automatic control switch, results in hand cramps to use.

The purpose of this utility model is to provide a kind of suction strong, easily the deodorizing toilet cover of installing and can controlling automatically.

The purpose of this utility model is achieved in that the utility model comprises seat ring and the toilet cover above the seat ring, seat ring and toilet cover are hinged on the pedestal respectively, the pedestal that is fixed on the sitting toilet has the exhaust passage, its inlet is being fixed on the screen pack seat ring corresponding with this exhaust passage inlet and is being had radial collecting chamber, the exhaust passage port of export stack that is being tightly connected, exhaust motor is fixed in the exhaust passage, it is fixing discharge fan on the axle of collecting chamber direction, have normally closed switch K on the end face of the corresponding toilet cover of pedestal ₃The contact, have normal open switch K on the end face of the corresponding seat ring of pedestal ₂The contact, the master switch K on the pedestal ₁With normal open switch K ₂, normally closed switch K ₃And the exhaust motor electrical connection of contacting in proper order.

The utility model is because the position of exhaust motor has strengthened pollution discharge capability, and insulation effect well also can be removed decontamination gas rapidly, cleaning ambient, the utility model is installed more convenient, and the power supply in the pedestal is all adopted the direct current of 6V, transformer is installed in outside the washroom, makes the utility model become safer.The semi-ring tubular structure that the utility model adopts is more suitable for pipeline in indoor installing and fixing, and it can directly adhere on the tile wall, can descend hidden pipe again.Master switch K on the utility model pedestal ₁Can use for the puerpera, because its water tank of toilet that the U.S. produces is positioned at the sitting toilet dead astern, unimpeded in order to guarantee the stack exhaust, stack can be drawn along tank outer wall and water tank bottom, is inserting ventilation opening then.

Below in conjunction with drawings and Examples the utility model is further described.

The utility model seat ring 1 top as shown in Figure 1 is toilet cover 2, and pedestal 3 makes movable pressing board 15 that pedestal 3 and whole machine body are fixed on the sitting toilet by set bolt 14 and sitting toilet tension.As shown in Figure 2, pedestal 3 has exhaust passage 4, and screen pack 5 is being fixed in its entrance, has radial collecting chamber 6 on the seat ring 1 corresponding with these exhaust passage 4 inlets, and collecting chamber 6 can adopt stainless steel to manufacture.Exhaust passage 4 ports of export stack 7 that is being tightly connected, stack 7 cross sectional shapes for semi-circular, can be used for holding power line 12 in the passage that ring 22 and wall form in it as shown in Figure 5.As shown in Figure 2, exhaust motor 8 plate 18 that is fixed is fixed in the exhaust passage 4, and its surface has electro-insulating rubber layer 13, and this exhaust motor 8 is being fixed discharge fan 9 on the axle of collecting chamber 6 directions, have normally closed switch K on the end face of pedestal 3 corresponding toilet covers 2 ₃ Contact 10, have normal open switch K on the end face of corresponding seat ring 1 ₂Contact 11.Normally closed switch K as shown in Figure 4 ₃The contact be pin 10, when toilet cover 2 was closed, it was under pressure, and will be pressed in the groove 16, then K ₃Disconnect.In pedestal one side a junction box 17 is arranged.Fig. 6 has provided the utility model circuit theory diagrams, the master switch K on the pedestal 3 ₁With normal open switch K ₂, normally closed switch K ₃And exhaust motor 8 order polyphones are electrically connected.Exhaust motor 8 is a direct current generator, and this circuit input end is furnished with transformer, bridge rectifier and filter capacitor C.As master switch K ₁After the connection, this moment, seat ring 1 and toilet cover 2 were not all opened normally closed switch K ₃Be pressed into groove 16, normally closed switch K ₃For disconnecting normal open switch K ₂The contact be compressed to on-state because this is a series circuit, so the circuit access failure, motor does not change, when toilet cover 1 is opened, normally closed switch K ₃Connect normal open switch K ₂Still for connecting, circuit is connected, and exhaust motor is a duty.When the user will be to the sitting toilet pouring, need again seat ring 1 is opened, be compressed on the normal open switch K in pedestal 3 grooves this moment ₂The contact throw off down circuitry.Exhaust motor quits work.Fig. 3 has provided fan 9 and the position of exhaust motor 8 in exhaust passage 4, and gas is discharged from by the gap of fan 9 with vias inner walls.Seat ring 1 has froth bed 20 in the present embodiment, and is very comfortable, and the toilet cover surface can adopt corium 19 to manufacture, and collecting chamber is stainless steel 21 structures, makes the utility model become more corrosion-resistant, more comfortable.As Fig. 7, the utility model shown in Figure 8, it is a kind of structure that is used with U.S.'s toilet, because its vertical water tank 21 of American toilet is positioned at a dead astern, pond, stack 7 is drawn along water tank 21 bottoms, and then the access ventilation opening, this kind structure has also guaranteed the convenience of toilet good looking appearance and installation simultaneously.
