In the figure, 1 is a box body, 2 is a filter cavity, 3 is a water outlet, 4 is a diversion slope, 5 is a primary filter cavity, 51 is filter cotton, 6 is a blow-off pipe, 61 is a blow-off valve, 7 is a water pump, 8 is a water inlet pipe and 81 is an isolation cage.

Detailed Description

The utility model is further elucidated below in connection with the accompanying drawings.

Referring to fig. 1, an embodiment of the present utility model is a convenient-to-clean plug-in filter, which comprises a box 1, wherein a filter cavity 2 is installed at the upper part of the box 1, the filter cavity 2 is communicated with a water outlet 3, the filter cavity 2 is also communicated with the upper part of a primary filter cavity 5, so that water in the primary filter cavity 5 can flow into the filter cavity 2 from the upper part for secondary filtration, a drain pipe 6 is also arranged at the lower part of the primary filter cavity 5, a drain valve 61 is installed on the drain pipe 6, the drain pipe 6 can be opened or closed through the drain valve 61, and impurities in the primary filter cavity 5 and water can be discharged together in a controllable manner, so that the filter can replace cleaning, a water pump 7 is also installed in the box 1, the water inlet end of the water pump 7 is communicated with a water inlet pipe 8, and the water outlet end of the water pump 7 is communicated with the primary filter cavity 5, so that sewage in a fish tank can be pumped into the primary filter cavity 5 by the water pump.

In this embodiment, through add leading initial filter chamber in box 1 for the sewage that draws in box 1 gets into first initial filter chamber 5 at first, and great debris such as fish just this moment, silt, rotten pasture and water etc. can deposit the cavity bottom under the action of gravity, and cleaner water then continues to rise and flow into the filter chamber, carries out the fine filtration of second grade through the filter medium in the filter chamber 2, can discharge the filth and the debris of deposit in initial filter chamber 5 bottom through the blow off pipe 6 of initial filter chamber 5 lower part, and then be convenient for wash, and the operation is also comparatively convenient.

Furthermore, in order to reduce the flow rate of the filtered water and reduce noise, a transverse diversion slope 4 can be additionally arranged on the water outlet 3, and meanwhile, in order to prevent the water pump 7 from sucking larger impurities in the fish tank into the primary filter cavity 5, an isolation cage 81 can be arranged on the water inlet of the water inlet pipe 8. More preferably, in order to enhance the filtering effect of the primary filter chamber 5, in this embodiment, the filter cotton 51 may be filled in the primary filter chamber 5, and the sewage entering the primary filter chamber 5 may be filtered by the filter cotton 51.

The filter structure described in the above embodiments shows that the external filter has an innovative front-end primary filter chamber based on the conventional design. The front filter cavity is internally provided with a layer of high-efficiency filter medium, so that a large amount of impurities and particulate matters can be intercepted in a preliminary stage, and the service life of the main filter is effectively prolonged. When water is drawn into the filter, it first enters this pre-filter chamber. Here, larger impurities such as fish feces, sediment, rotten pasture and the like can be deposited to the bottom of the cavity under the action of gravity, and cleaner water continuously rises and is subjected to secondary fine filtration through the filter medium, so that purer water quality is finally obtained.

More importantly, the blow-down switch (the blow-down pipe 6 and the blow-down valve 61) is designed at the bottom of the pre-arranged primary filter cavity 5. When the filter needs to be cleaned, the user does not need to detach the heavy complete machine, and can easily discharge the dirt and sundries deposited at the bottom of the front filter cavity by only slightly twisting the dirt discharging switch. The simple and practical design greatly reduces the labor intensity of users and saves the cleaning time. In addition, this design also contributes to environmental protection, as it reduces the need for frequent replacement of the filter, reducing the pressure on the environment from the waste filter. Meanwhile, the preposed filter cavity can effectively catch large-particle impurities, which also means that the replacement frequency of the main filter is reduced, thereby reducing the overall use cost.

In a word, this novel external filter by virtue of its leading filter chamber and convenient blowdown switch design, not only improved filtration efficiency, more importantly greatly simplified the cleaning process for daily maintenance becomes more light. The push of the household articles provides a more ideal choice for families pursuing high-quality life, and simultaneously shows the trend of the household articles towards more humanization and environmental protection. With the continuous pursuit of healthy life quality, the innovative design is more favored in the market.
