the second end of the mounting location post 125 is disposed toward the outside of the lower housing 117. The positioning post 125 facilitates quick installation of the filter device 100.
Optionally, the outer side of the second end of the mounting positioning column 125 protrudes outwards to form a boss, so that the mounting positioning column 125 is prevented from sliding out of the mounting groove of the water dispenser, and the mounting stability of the filtering device 100 is improved.
Referring to fig. 3, the present application further provides a pet water dispenser, including: a filter device 100;
the filter device 100 includes: a filter element housing and a filter element;
the filter element is arranged in the filter element shell;
the filter element and the filter element shell form a water purifying channel for filtering water;
a straight drainage channel is also arranged in the filter element shell;
wherein the water purification channel and the direct drainage channel share the same water inlet 112; and the water flowing out from the water purifying channel and the direct water discharging channel is mixed in the filter element shell and then discharged.
In the embodiment, the purified water discharged from the purified water channel is mixed with the water directly discharged from the straight water discharge channel and then discharged, and after the filtering device 100 is used for a period of time, the filtering device 100 can always discharge water outwards; in the circulating filtration scene, water discharged from the direct water discharging channel is purified in the subsequent circulating filtration, so that the effect of circulating filtration is not influenced; and when impurities are accumulated in the filter element to cause that the water purification channel can not discharge water, the water can still be discharged through the direct water discharge channel, so that the phenomenon that the water pump can not convey water to the filtering device 100 to be burnt due to continuous water pumping is avoided.
Referring to fig. 3, in one embodiment, the pet water dispenser further includes: a water tray 200, a water tank 300 and a water pump;
the drinking water tray 200 is positioned above the water tank 300;
the drinking water tray 200 is communicated with the water tank 300 so that the excessive water in the drinking water tray 200 flows into the water tank 300;
the water pump is positioned in the water tank 300;
the water inlet 112 of the filter device 100 is communicated with the water outlet of the water pump;
the water discharged from the pure water passage and the direct water passage is mixed in the filter element housing and then flows into the water tray 200. The water purification device has the advantages that when the circulating filtration scene is carried out, water discharged from the direct-discharge water channel is purified in the subsequent circulating filtration, so that the effect of circulating filtration is not influenced.
In one embodiment, the filter device 100 is movably mounted on an outer wall of the water tank 300. It is understood that the filter device 100 may also be fixedly mounted on the outer wall of the water tank 300.
In another embodiment, the filter device 100 is removably mounted within the water tank 300. It is understood that the filter device 100 may also be fixedly mounted within the water tank 300.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, apparatus, article, or method that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, apparatus, article, or method. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, apparatus, article, or method that includes the element.
The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application, or which are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
