Description

Odour-proof floor drain

Technical field

The present invention relates to the piping facility field, particularly, relate to a kind of floor drain.

Background technology

Need the place of water at common washroom, kitchen, balcony etc., floor drain generally all can be installed, flow into sewer so that flow to the water on ground from floor drain.For the peculiar smell that prevents sewer is upwards leapt up, the pipe that leaks of floor drain is communicated with one section pass-over offset usually, and this pass-over offset is folded to the top from the pipe lower end that leaks; Like this structure, can make leaks in the floor drain leaves one section water body between pipe lower end and the pass-over offset all the time, and this section water body can block on the peculiar smell in the sewer leaps up.

Yet, together flowing to floor drain owing to often having the foreign matter such as hair with water body, this just a problem occurred, manages between lower end and the pass-over offset leaking of floor drain in order not make hair obstruction, and the upper surface of floor drain must arrange filter, has stopped hair; But on the one hand, because the configuration of filter, so that the water flowing area of floor drain is very limited, the speed of leaking is received very large restriction; On the other hand, often can tangle a large amount of hairs in the filter, have a strong impact on the speed of leaking; Need to manually remove hair can normally use, and this locates in the hotel etc. is very inconvenient.

Summary of the invention

For the problems referred to above, the object of the present invention is to provide a kind of odour-proof floor drain, this kind odour-proof floor drain not only can effectively prevent from leaping up on the peculiar smell in the sewer, and can be by hair obstruction.

The technical solution adopted for the present invention to solve the technical problems is: this odour-proof floor drain comprises a cylindrical cushion chamber, and the sidewall top of described cushion chamber has and the integrated ring eaves of sidewall; The bottom surface of described cushion chamber is a taper surface; The middle part of described taper surface is to straight of downward-extension pipe that leaks; Be provided with a ball float in the described cushion chamber; The top of described cushion chamber is provided with a water flowing cover plate, and each through hole on the described cover plate satisfies following condition: the area of each through hole is greater than 3.14cm2, and described ball float can not pass each through hole.

As preferably, the internal diameter of the described pipe that leaks is 3cm ~ 6cm; The sphere diameter of described ball float is 1.41 times of the described bore that leaks; The internal diameter of described cushion chamber is 1.4 ~ 1.6 times of described ball float sphere diameter; The height of described cushion chamber satisfies following condition: described ball float foot in the described cushion chamber moves upward to topmost, and shift length is 1.3 ~ 1.6 times sphere diameter.

As preferably, the weight of described ball float is 50g ~ 100g; Can be consisted of by the hollow plastic pellet.

Beneficial effect of the present invention is: this odour-proof floor drain in use, when not having water body to flow into floor drain on ground, described ball float is lived the pipe plug that leaks of floor drain under action of gravitation just, thereby prevents that the peculiar smell in the sewer from upwards leaping up out; And when surface water body flows into floor drain, the water body in the floor drain cushion chamber will make ball float upwards float, thereby the pipe mouth of pipe that leaks is exposed, and water body gets final product smooth and easy inflow sewer; Owing to there not being the pass-over offset of common floor drain, therefore, the foreign matters such as hair can not be blocked in the floor drain, can flow directly into sewer, therefore, floor drain top need not to arrange filter, a cover plate that is used for retraining described ball float only need be set get final product, through hole on this cover plate can be tried one's best greatly, and only not so ball float is leapt up out; This has just been avoided hair to tangle at the floor drain upper surface.

Fig. 2 is the vertical profile structure chart of Fig. 1 embodiment under hull-borne.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples:

In the embodiment shown in fig. 1, this odour-proof floor drain comprises a cylindrical cushion chamber 10, and sidewall 1 top of described cushion chamber 10 has and the integrated ring eaves 11 of sidewall; The bottom surface of described cushion chamber 10 is a taper surface 12; The middle part of described taper surface 12 leaks to straight of downward-extension and manages 4; Be provided with a ball float 3 in the described cushion chamber 10; The top of described cushion chamber 10 is provided with a water flowing cover plate 2, and each through hole on the described cover plate 2 satisfies following condition: the area of each through hole is greater than 3.14cm2, and described ball float 3 can not pass each through hole; Here, when described through hole was circular hole, namely the aperture of each through hole was greater than 2cm, and the aperture of described through hole should be large as far as possible, only needed to guarantee that not allowing ball float 3 leap up out gets final product, and like this, hair just is difficult for tangling between described through hole.

The described internal diameter that leaks pipe 4 is 3cm ~ 6cm; The sphere diameter of described ball float 3 is the described pipe 1.41 times of 4 internal diameters of leaking, and like this, is pressed in when leaking pipe 4 mouth of pipe at ball float 3, according to geometrical relationship, the leak line of arbitrfary point and ball float 3 centre ofs sphere on pipe 4 mouth of pipe bearing edges, with the vertical curve angle be 45 °, i.e. angle α=45 ° among Fig. 1; This angular relationship both can make ball float 3 firmly be held on the pipe mouth of pipe that leaks under the floor drain non-displacement condition, can ensure again floor drain when draining, and the water in the cushion chamber 10 can upwards boost ball float 3 reliably from second sphere of ball float 3.

The internal diameter of described cushion chamber 10 is 1.4 ~ 1.6 times of described ball float sphere diameter; The height of described cushion chamber satisfies following condition: described ball float foot in the described cushion chamber moves upward to topmost, shift length is 1.3 ~ 1.6 times sphere diameter, so size can guarantee that ball float is comparatively freely mobile in cushion chamber 10, and the draining of floor drain can smooth and easyly be carried out.

The weight of described ball float 3 is 50g ~ 100g; Can be consisted of by the hollow plastic pellet.

Above-mentioned odour-proof floor drain is when non-displacement condition, and described ball float 3 is just blocked the pipe 4 that leaks of floor drain under action of gravitation, thereby prevents that the peculiar smell in the sewer from upwards leaping up out; And when hull-borne, as shown in Figure 2, when surface water body flows into floor drain, the water body in the floor drain cushion chamber 10 will make ball float 3 upwards float, thereby pipe 4 mouths of pipe that leak are exposed, and water body gets final product smooth and easy inflow sewer; Owing to there not being the pass-over offset of common floor drain, therefore, the foreign matters such as hair can not be blocked in the floor drain, can flow directly into sewer, therefore, floor drain top need not to arrange filter, a cover plate 2 that is used for retraining described ball float 3 only need be set get final product, through hole on this cover plate 2 can be tried one's best greatly, and only not so ball float is leapt up out; This has just been avoided hair to tangle at the floor drain upper surface.

This odour-proof floor drain is simple in structure, is easy to promote, and extremely is applicable to the public residences such as hotel.

The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
