Description

Technical Field

[0001] The invention relates to the technical field of water source purification, and in particular to a water source purification device for a trailer-type RV. Background Art

[0002] When traveling by car, you can take your family to go wherever you want, stop whenever you want, and leave whenever you want, without any restrictions, and completely integrate into the depths of nature. Various problems often occur during self-driving in an RV, the most important of which is how to replenish water. Water is an important component of the human body and a necessary medium for metabolism.

[0003] A water purification device for trailer RVs with a Chinese authorization announcement number of CN 211198930 U, which pumps external water into a sedimentation tank through a water pump. At the same time, the alkaline storage tank releases a portion of alkaline substances to neutralize the water in the sedimentation tank, thereby increasing the pH value of the water body and causing most heavy metals to precipitate as hydroxides. The water then flows into the filter box through a connecting pipe. The filter screen on the top layer of the filter box performs preliminary filtration to filter out obvious impurities. Secondly, it undergoes deep filtration through three layers of different filter sands. The filtered water flows into the cavity at the bottom of the filter box through a water seepage plate.

After the water source is filtered through the filter component 11, it flows from the first connecting pipe 20 to the sterilization chamber 16, and then drives the driving motor 907 to control the bevel gear rod 906 to rotate.
