[0033] The following further describes the detailed implementation manners of the present utility model with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0034] Such as Figure 1 And Figure 2The following shows a urinal according to an embodiment of the present utility model, which includes: a urinal bowl 1, a fixing bracket 2, a first water pipe 3, a water inlet valve 4, a filter element 5, and a nozzle 6. The fixing bracket 2 is fixedly connected to the urinal bowl 1. The nozzle 6 is fixed within the fixing bracket 2. The water inlet valve 4 is connected to the nozzle 6 through the first water pipe 3 to form a water inlet pipe path for the nozzle. The filter element 5 is located in the water inlet pipe path for the nozzle, and a preparation for inhibiting water scale is contained within the filter element 5.

[0035] Specifically, the fixing bracket 2 is fixed on the urinal bowl 1, and the nozzle 6 is fixed on the fixing bracket 2. Preferably, the fixing bracket 2 is fixed on the back of the urinal bowl 1. A nozzle mounting hole 11 is provided on the urinal bowl 1, and the nozzle 6 extends out from the nozzle mounting hole 11 for spraying water into the urinal space surrounded by the surface of the urinal bowl 1 to clean the urinal bowl 1.

[0036] The water inlet valve 4 is connected to the nozzle 6 through the first water pipe 3 to form a water inlet pipe path for the nozzle. The filter element 5 is installed in the water inlet pipe path for the nozzle. A preparation for inhibiting water scale is contained within the filter element 5.

[0037] As Figure 5 shown, in some embodiments, the filter element 5 includes a filter element accommodation cavity 52, a filter element water inlet 53 communicating with the filter element accommodation cavity 52, and a filter element water outlet 54. A preparation 55 is contained within the filter element accommodation cavity 52.

[0038] The preparations for inhibiting water scale include chemical preparations and non-chemical preparations.

[0039] The chemical preparations include, but are not limited to: polyphosphates (such as sodium hexametaphosphate (SHMP), tetrapotassium pyrophosphate (TKPP), etc.), low pH acids (such as hydrochloric acid (HCl)), dihydrogen phosphate (H2PO4), trisodium phosphate (TSP), ethylenediaminetetraacetic acid (EDTA), and their combinations, as well as other acids and / or chelating agents. These preparations may be beneficial for, for example, preventing and / or removing water scale. Other examples of preparations that can be used in the system of the present application include (but are not limited to) didecyldimethylammonium chloride (DDAC), H2O2, sodium hypochlorite (NaClO) (such as bleach), peracetic acid (PAA), dichlorophenol, formic acid, TSP, and their compounds, as well as other disinfectants (such as quaternary ammonium salt disinfectants) and biocides. These preparations may be beneficial for, for example, preventing and / or removing biofilms.

[0040] Non-chemical agents for reducing (e.g., decreasing, removing, etc.) scale and other contaminants can also be employed. One such example is the use of beads (e.g., flowing beads, media, etc.) as non-chemical agents for inhibiting scale, which may involve template-assisted crystallization (TAC). Certain minerals (e.g., calcium, magnesium, etc.) can attach to a surface (e.g., the inner surface of the urinal bowl of a toilet) when in an ionic form (e.g., in the ionic state), but do not attach to the surface when crystallized (i.e., in the crystalline form). Beads involving TAC change the minerals from their ionic form to their crystalline form to prevent the minerals from attaching to the system surface and / or induce the minerals to leave the surface. Thus, the flowing beads can utilize the interaction and / or friction of the materials to help clean the system surface by preventing mineral deposits from attaching to the surface and / or knocking down the mineral deposits attached to the surface.

[0041] The flushing water of the urinal is sprayed on the surface of the urinal bowl of the urinal 1 after passing through the scale-removing filter element 5.

[0042] For the urinal of the present utility model, a filter element is added to the nozzle water inlet pipeline formed by connecting the water inlet valve, the water pipe and the nozzle. Through the scale inhibitor in the filter element, the substances in the water entering the nozzle are inhibited, and the scale inhibition effect is good. Moreover, the structure is simple and the filter element is convenient to replace.

[0046] Among them, the filter element 5 is detachably connected to the nozzle 6. When the filter element 5 needs to be replaced, the filter element 5 and the nozzle 6 are pulled out, the filter element 5 is removed from the nozzle 6, a new filter element is replaced, the water pipe is connected, and then the nozzle 6 and the filter element 5 are reinserted into the nozzle mounting hole 11. Among them, the water pipes of the present utility model and other components are all detachably connected. When replacing the filter element, the water pipe can be disassembled from other components for replacement. After replacement, the water pipe can be connected to other components to restore the water circuit.
