The specific embodiment
With reference to the accompanying drawings to the concrete structure of a kind of embodiment of cup shape odour seal of the present utility model.
As shown in Fig. 1-5, odour seal 1 comprises a columnar body 2, and roof 3 tops of this body 2 have a water inlet that protrudes upward 4, the sidewall 5 of columnar body 2 have one cross out anhydrate mouthfuls 6, an and opposed horizontal air intake 7.As shown in Figure 5, be integral from the below of the roof 3 of body 2 and stretch out an entry pipe 8 downwards, it is connected with water inlet 4.The lower end of entry pipe 8 connects the big slightly tubular body of a diameter 9, constitute a valve seat 10 on the inwall of the junction of this tubular body 9 and entry pipe 8, also can be provided with a rubber washer 11 on the valve seat, can simplify the processing of valve seat, simultaneously, when the prooving of valve seat, can repair valve seat by changing rubber pad 11.Being provided with by lower end position of the sidewall 5 of body 2 connects with external screw thread 12, puts rubber washer 13 on it.
As shown in Fig. 1-3 and 5, odour seal 1 also comprises a U-shaped cup 14, the upper shed inwall of this U-shaped cup 14 is provided with on the external screw thread 12 of internal thread 15 in order to the lower end of the sidewall 5 that is connected body 2, and the rubber washer 13 that is contained between U-shaped cup and the body 2 can make U-shaped cup and body interior and room atmosphere isolated.U-shaped cup 14 can be filled water after being sealedly connected on body 2 lower ends in the U-shaped cup, and as can be seen from Figure 5, the tubular body 9 of entry pipe 8 lower ends of body 2 is to be positioned at U-shaped cup 14 inside.Place the diameter ball float 16 bigger than the internal diameter of entry pipe 8 in tubular body 9, this ball float 16 can raise along with the rising of the water level in the U-shaped cup 14, as shown in phantom in Figure 5, leans at last on valve seat 10, with 8 sealings of entry pipe.
Also illustrate among Fig. 5, odour seal 1 comprise one can link to each other with the outfall (not shown) of sanitary equipment such as wash-hand basin go into tap 20, this is gone into tap 20 and is plugged in the water inlet 4 of body 2, can utilize on the external screw thread 23 that the rubber cushion 21 that is placed between the two and hold-down nut 22 be tightened in water inlet 4 peripheries and the two is fixed and seal up in the junction.Anhydrating of body 2 mouthfuls 6 can link to each other with the larynx 25 that anhydrates, and can utilize the external screw thread 28 on the periphery that rubber cushion 26 between the two and hold-down nut 27 be tightened in the mouth 6 that anhydrates equally and the two is fixed and seal up in the junction.
The working condition of cup shape odour seal 1 of the present utility model is described below with reference to Fig. 5.When sanitary equipment (not shown) not during draining, the waters in the U-shaped cup 14 float ball float 16, and it is leaned on valve seat 10, thereby with 8 sealings of entry pipe.Water level in the U-shaped cup 14 can reach the bottom face position of the mouth 6 that anhydrates.When the sanitary equipment draining, water flows into entry pipes 8 by going into tap 20, and ball float 16 is opened valve seat 10 to pressing down, and the sidewall 5 by U-shaped cup 14, body 2 is with the passage between the entry pipe 8 and from anhydrating mouthfuls 6 to larynx 25 discharges of anhydrating then.Thereafter, when sanitary equipment stopped draining, ball float 16 upwards floated under the effect of buoyancy of water and leans valve seat 10, once more with 8 sealings of entry pipe.So, can prevent that sewage and oxious gas are back to sanitary equipment.And return pressure is big more, and the active force that ball float 16 leans valve seat 10 is also big more, and the effect of anti-backflow strengthens more.
When odour seal 1 anhydrate very anxious the time, certain vacuum state can be caused in the space that is positioned at more than the water surface at body 2, at this moment tend to make anhydrate not smooth, therefore, where necessary, can consider to set into air valve 30 on odour seal, this air inlet valve can make room air enter in the odour seal 1, but sewage or oxious gas in the larynx 25 that do not allow to anhydrate are back to indoor by odour seal 1.
Fig. 5 illustrates the concrete structure of a kind of air inlet valve 30 of the utility model.Air inlet valve 30 comprise a tubular shell 31 that links to each other with the air intake 7 of body 2 with one be bent upwards after these tubular shell 31 levels are connected L shapedly go into tracheae 32, go on the inwall of tracheae 32 and the junction of tubular shell 31 to constitute a valve seat 33, a rubber washer 34 also can be set on the valve seat 33 to simplify the processing of valve seat.The lower position by valve seat 33 in tubular shell 31 is provided with a slope 34 that upwards tilts a little, one spherosome 35 is set on slope 34, under the effect of the deadweight of the ramp structure on slope 34 and spherosome 35, spherosome 35 leans valve seat 33, thereby will go into tracheae 32 sealings.When being positioned at space more than the water surface and causing certain vacuum of the body 2 of odour seal 1, indoor air backs down spherosome 35 valve seat 33 is opened by going into tracheae 32, thereby enter the upper space of odour seal 1, but, when the return pressure of sewage in the larynx 25 that anhydrates or oxious gas increases and when acting on the spherosome 35,35 of spherosomes closely lean will go into tracheae 32 and seal on valve seat 33, sewage in the larynx 25 that therefore can prevent to anhydrate or being back to tracheae 32 of oxious gas and in the inlet chamber.And return pressure is big more, and the effect of anti-backflow more increases.
Several enforcement structures of above-mentioned air inlet valve 30 of the present utility model have detailed introduction in applicant's application number is another piece Chinese patent application of CN03208491.9.The content of this patent is combined in the utility model by reference.
Introduced a kind of preferred embodiment of the utility model cup shape odour seal above in conjunction with the accompanying drawings, but, the utility model is not limited, and those of ordinary skills can both understand, and can make various changes and remodeling in spirit and scope of the present utility model.For example, in the present embodiment, body 2 is a kind of drums, but it can be four limits or polygon cylindrical form.In addition, tubular body 9 is being the circle tubular body shown in the accompanying drawing of present embodiment, but it also can be four jiaos or polygonal tubular body, also can be horn-like body.In addition, U-shaped cup 14 with also can not adopt being connected of body 2 bottoms be threaded and adopt other as connected modes such as buckle syndetons, wherein also can not adopt rubber washer and adopt fluid sealant etc. to realize sealing.In addition, in the present embodiment, what adopt is to utilize ball float 16 to seal the structure of the valve seat 10 of oral siphon 8, but also be not limited to this structure, the structure of the circular kickboard capping valve seat that for example can pivot can also be adopted, all the purpose of this utility model can be realized as long as in general odour seal, add the structure of unidirectional stop valve around the fulcrum of valve seat one side.
