Specific embodiment

In order to be clearer and more clear technical problem to be solved in the utility model, technical solution and beneficial effect, with Under in conjunction with the accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein Example is applied only to explain the utility model, is not used to limit the utility model.

As shown in Figures 2 to 4, a kind of toilet bowl sewage draining pipe, 1 entrance of sewage pipe are connected with closestool urinal bottom 2, the row The dirty outlet of pipe 1 is connected with extraneous sewage pipe (not shown), and 1 inner wall of sewage pipe has at least a protrusion and/or recess portion, Specifically, protrusion is to be outwardly protruded to be formed by 1 inner wall of sewage pipe, recess portion is to be inwardly recessed to be formed by 1 inner wall of sewage pipe, this In embodiment, sewage pipe 1 is a siphon piping that can form siphon, and sewage pipe 1 is integrally formed in the toilet seat body.

In the present embodiment, the inner wall of the sewage pipe 1 has several protrusions and several recess portions, the protrusion and recessed Portion is alternately arranged and transition connects to form a bellows segment R, that is, protrusion forms the wave crest R1 of bellows segment R, recess portion forms bellows segment The trough R2 of R；In the present embodiment, the difference in height between the wave crest R1 and trough R2 of the bellows segment R is not less than 1.5mm；This reality It applies in example, bellows segment R is the wave-like of rule, distance (i.e. period) range between the two adjacent peaks R1 of the bellows segment R In 35mm-45mm, the contact area between 1 inner wall of sewage pipe and MISO medium 3 can be greatly reduced by the way that bellows segment is arranged, thus Reduce frictional force between the two, it is easier to which the siphon power of water flow siphons away MISO medium 3, and toilet tube is not easy to plug.

Certain the present embodiment can also use, and protrusion connects to form irregular wave-like with recess portion transition, either, The recess portion that the present embodiment is inwardly recessed only with formation, then either, only with the protrusion for forming outwardly convex, concrete form is not It is restricted, as long as final realize the contact area for reducing sewage pipe 1 inner wall and MISO.

In the present embodiment, the sewage pipe 1 include along drainage direction successively arc transition connection into dirty section 11, changeover portion 12 and blowdown section 13.Described to extend obliquely upward into dirty section 11 along the rear of the closestool, the end into dirty section 11, which turns to, to be connected The starting point of the changeover portion 12 is connect, the changeover portion 12 extends obliquely along the front of the closestool, 13 edge of blowdown section The front horizontal of the closestool extends.

In the present embodiment, at least described inner wall into dirty section 11 has the protrusion and/or recess portion, can also use On into any the two of dirty section 11, changeover portion 12 and blowdown section 13 or whole threes are equipped with the protrusion and/or recess portion.

The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new Type is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various other groups Conjunction, modification and environment, and above-mentioned introduction or the technology of related fields can be passed through within the scope of the inventive concept described herein Or knowledge is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, then It all should be in the protection scope of the appended claims for the utility model.
