Abstract

The utility model relates to a flushing-free filter for a pedestal urinal, which comprises an outer box body (1), wherein an inner cavity of the outer box body (1) is provided with an overflow pipe (2) and an inner box body (3) with an opening arranged at the upper part. The bottom (31) of the inner box body (3) is provided with a water leaking hole (31a) and keeps distance with the bottom of the outer box body (1), a filtering granular layer (5) is arranged above the bottom (31) of the inner box body (3), and an oil sealing layer (7) is arranged above the filtering granular layer (5). The overflow pipe (2) is positioned outside the inner box body (3), the upper end of the overflow pipe is opened at the inner cavity of the outer box body (1) and is higher than the filtering granular layer (5), and the lower end is directly opened outside the outer box body (1). The utility model is compared with the prior art, the oil sealing layer of the utility model with the block of the filtering granular layer and the bottom of the inner box body can not be flushed out or lost even under the water flow impact with certain impact force, and the oil sealing layer always floats at the surface of detaining urine in the inner box body under the function of buoyancy force; thus, the utility model prevents the detaining urine from being oxidated by the air and prevents bad smell from emitting.

Description

A kind of flush-proof filtration apparatus of exempting from that is used for stall urinal

Technical field

The utility model relates to the sanitary installation that a kind of lavatory is used, particularly a kind of flush-proof filtration apparatus of exempting from that is used for stall urinal.

Background technology

At present, stall urinal is widely used in the washroom or public lavatory of various public arenas, and traditional stall urinal is flushing type, and the bottom of its body has weep hole and is connected with sewer pipe, for preventing that foreign matter from stopping up, generally also be coated with a filter lid on the weep hole; Usually, this sewer pipe has a U-bend portion, to preserve a certain amount of water as water seal, the foul smell in the isolated sewer.Because urine can produce foul smell after air oxidation, so stall urinal generally also is equipped with the automatic or manual flusher, be used for flushing the toilet after use, however, water in this U-bend portion still is the mixed liquor of urine and flushing water, after air oxidation, still can produce foul smell inevitably.And in today of water resource growing tension, the water consumption of this bath device that is widely used in stall urinal is still very considerable.For this reason, the patent No. is that the Chinese utility model patent " exempting from the stall urinal of washing by water " (notification number is CN2559699Y) of ZL02246629.0 has disclosed a kind of stall urinal of washing by water of exempting from, its body bottom is provided with a tank and is communicated with sewer, and the collecting hindering machine that is made of collection urine tube, excrement overflowing pipe, cover and oil sealing layer is installed in the tank; Collection urine tube be installed in the tank and with the suitable for reading and inner wall sealing of tank; Excrement overflowing pipe both ends open and the central authorities that urine collecting barrel is installed, its lower end is passed the tube end of collection urine tube and is communicated with sewer; Cover is conical and buckle closure suitable for reading at tank and collection urine tube, between certain slit is arranged, the cover bottom center is extended downwards and is provided with an inner core and is set in the excrement overflowing pipe periphery; Going up of urine shown in the floating urine collecting barrel of oil sealing layer.This design scheme has been owing to set up an oil sealing layer on the surface of water seal, thereby solved the problem because of the oxidized effusion foul smell of the water in the water seal effectively.But therefore, under oil sealing, do not have special barrier structure in this design scheme, at urine liquid or under the bath when cleaning this urinal impacted, oil sealing was easy to be flushed away, run off with certain impulse force.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of oil sealing wherein to be difficult for the flush-proof filtration apparatus of exempting from that is used for stall urinal that runs off at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this flush-proof filtration apparatus of exempting from that is used for stall urinal includes an outter box, is provided with the inner box of a bleed off pipe and a upper opening at the inner chamber of outter box; The bottom of described inner box have leaking hole and and the bottom of outter box between leave spacing, and on the bottom of inner box, be provided with the filtering particle layer, on the filtering particle layer, be provided with the oil sealing layer; Described bleed off pipe is positioned at outside the inner box, and its upper end open is in the inner chamber of outter box and be higher than the filtering particle layer of inner box, and its lower end then directly is opened on outside the outter box.

In order further to stop the loss of oil sealing layer, between described inner box bottom and filtering particle layer, also can be provided with a filter net sheet.

Described inner box can be one-body molded with outter box, also can form by the roughly L-shaped dividing plate in cross section.Equally, described bleed off pipe can be one-body molded with outter box, also can be used as a separate piece and be connected with outter box.

Described outter box can be uncovered, also can cover with a capping, and this is sealed on the corresponding position of inner box and has leaking hole or bring water pipe into, to be fit to different occasions.

Compared with prior art, oil sealing layer of the present utility model is owing to have the filtering particle layer and the obstruct of inner box bottom, even can not be flushed away yet, run off having under the water impact of certain impulse force, and under buoyancy function, all the time swim in the surface of the delay urine of inner box, thereby stop the effusion of being detained urine oxidation by air and foul smell.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, be embodiment one of the present utility model, it includes an outter box 1, is positioned at bleed off pipe 2 outside the inner box 3 at the one-body molded inner box 3 and that a upper opening arranged of the inner chamber of outter box 1;

The bottom 31 of described inner box 3 have leaking hole 31a and and the bottom of outter box 1 between leave spacing, and on the bottom 31 of inner box 3, be provided with a filter net sheet 4, on filter net sheet 4, be provided with filtering particle layer 5, be provided with oil sealing layer 7 on filtering particle layer 5, this oil sealing layer 7 swims in the surface of the delay urine 6 of inner box 3;

The upper end open of bleed off pipe 2 is in the inner chamber of outter box 1 and be higher than the filtering particle layer 5 of inner box 3, and the lower end of bleed off pipe 2 then directly is opened on outside the outter box 1.
