(5) specific embodiment
At first, wherein show first embodiment according to waterless urinal 10 of the present invention referring to Fig. 1.Urinal 10 has the interior basin surface 12 that has outlet 14.Fig. 1 also shows first embodiment according to removable cartridge assembly 16 of the present invention.Cartridge assembly 16 is installed in the opening 14 and by pipe 18 and is connected with urban sewage pipe.
Cartridge assembly 16 is clearly shown that in Fig. 2 to 7, and has and be generally columniform plastic body 20.Main body 20 has external screw thread 22 at one end, and has terminal bifurcated tapered portion 24 on the other end.Tapered portion 24 ends at a flange 26, and this flange is applicable to after installation 14 sealings of the opening in the urinal inner surface 12.Cartridge assembly 16 is inserted from the inside of urinal through opening 14, and by screwing nut 28 along screw thread 22, engage up to its lower edge 14a with outlet 14, thereby cartridge assembly 16 is fixed.
Rubber check valve 30 places main body 20 by the external flanges on the main body 20 34, and this check valve is placed against the internal shoulder 36 of the inside of main body 20.Valve 30 is types that the front had been described, and has elastic wall 38 (see figure 7)s, and this wall opens and separates, so that urine is passed through downwards, is closed to the described position of Fig. 7 then automatically and upwards overflows thus to prevent smell.
The top of valve 30 has four registration arm 40, and they are suitable for and 42 interlocks of plastics cup shell.Cup shell 42 is suitable for holding fragrance or deodorant blocks 44.Crooked slightly plastic closure 46 releasably is connected with cup shell 42 by all protuberances 48 on the cup shell 42, and protuberance 48 engages with corresponding all openings 50 on the lid 46.Can press lid 46 is taken away from cup shell 42 by protuberance 48 inwardly being left opening 50 ground.Operation to protuberance 48 can prevent from without approval cartridge assembly 16 to be pulled down (for example the someone sabotages), and just as will be discussed later in detail, this makes him be applicable to the public arena.
Lid 46 is placed between the top of lid 46 and flange 26 and reserves the high gap of about 9mm 52.In use, urine enters in the gap 52 along basin surface 12, by cartridge assembly 16 and valve 32, enter in the urban sewage pipe through pipe 18.Gap 52 also can make the smell from the pleasant of fragrance piece 44 enter in the room that urinal 10 is installed.
Filter cylinder described above and urinal have several advantages.At first, this filter cylinder is very easy to install and use.Installation, dismounting or replacement fragrance piece 44 are also very convenient, and do not need filter cylinder 16 is pulled down from urinal 10.Second, just from outstanding, slightly protruding camber line (almost being flat) the slightly lids 46 of adjacent inner surface 12 of urinal 10 be installed as cartridge assembly 14 and urinal 10 provides visual appearance attractive in appearance, unobtrusive because look that lid is consistent with the in-profile of basin.When from top when directly looking down this point especially obvious, and this also visual angle of most of users of urinal 10 just.
Figure 16 to 20 shows an embodiment according to cartridge assembly dismounting of the present invention and erecting tools 60.Instrument 60 has handle 61, is applicable to first end 62 that selectively engages with lid 46 and is applicable to second end 64 that selectively engages with fragrance piece 44.
First end 62 of instrument 60 has fixedly clamp 66 and removable clamp 68.Removable clamp 68 is connected with button 70, and as clear illustrating among Figure 18, button is depressed (shown in arrow 72) towards tool body 61 can make removable clamp 68 remove (shown in arrow 74) from tool body 61, thus the distance between the increase clamp 66 and 68.Instrument 60 also comprises spring 76, when on button 70, not having pressure, this spring with clamp towards (minimum aperture) the position bias voltage shown in Figure 16 to 20.
In use, the user depresses button 70 to increase the gap between the clamp 66,68.This can enter in the gap 42 clamp 66,68 through the over top of lid 46.When the pressure on the release-push 70, clamp 66,68 moves inward and contacts protuberance 48, and protuberance 48 moved inward and breaks away from joint in opening 50, and this will make lid 46 break away from and the engaging of cup shell 42.Lid 46 continues to be clipped by clamp 66,68, can from cartridge assembly 16 it be taken out then.
Process similar to the above can also be used for cup shell 42 being clamped and being taken out from cartridge assembly 16.
Can reverse use said process and new cup shell 42 and fragrance piece 44 are reinstalled, and also can reinstall lid 46.
Second end 64 of instrument 60 comprises the end construction 76 that is suitable for flange 34 interior bonds relevant with check valve 30.End construction 76 also comprises clamping part 78, and it can slide with respect to internal structure 82 on the direction of double-headed arrow 80.
In use, clamping part 78 first end 62 that slips away.Press down end construction 76 then, make it to engage with check valve 30.Instrument 60 can be caused valve 30 is pulled down from cartridge assembly 16 from cartridge assembly 16 extractions.Then, clamping part 78 towards first ends 62 back slide, and this can cause internal mechanism 82 against living valve 30 and forcing valve and end construction 76 disengages, and waits disposal.
Can reverse use said process and the check valve of replacing 30 is put in the cartridge assemblies.
Should be noted that instrument 60 makes people lid 46, cup shell 42, fragrance piece 44 and check valve 30 can be removed and/or change from cartridge assembly 16 and need not contact other any element of these or cartridge assembly.From the health aspect, this is an advantage.
Fig. 8-11 shows second embodiment according to removable cartridge assembly 16 ' of the present invention.Similar with shown in Fig. 1 to 7 of cartridge assembly 16 ', and identical numeral is to be used for representing the feature identical with first embodiment.Yet the lid of cartridge assembly 16 ' 46 is made of opal glass, and does not resemble first embodiment and cup shell 42 interlocks.On the contrary, lid 46 just seat at the top of cup shell 42 and rely on the quality of himself to keep position shown in the figure.As a result, this cartridge assembly is applicable to family expenses or other non-public arena.
Figure 12-15 shows according to removable cartridge assembly 16 of the present invention " the 3rd embodiment.Cartridge assembly 16 " similar with shown in Fig. 1 to 7, and identical numeral is to be used for representing the feature identical with first embodiment.Cartridge assembly 16 " have the lid 46 that releasably is connected by all protuberances 48 with cup shell 42, protuberance 48 engages with corresponding all openings 50 of lid bottom.As a result,, cartridge assembly 16 similar with first embodiment of cartridge assembly 16 " thus also needing tool using 60 that lid 46 is pulled down can get at fragrance piece 44, and also can guard against and sabotaging, so just be applicable to the public arena.
Though described the present invention by the reference instantiation, those skilled in the art can know that also available many other modes implement the present invention.
