Description

Technical Field

[0001] This utility model relates to the field of direct drinking water machines, and more specifically, to a direct drinking water machine with a circulation structure. Background Technology

[0002] With social development and the improvement of people's living standards, the requirements for drinking water quality are becoming increasingly stringent. At the same time, water scarcity and water pollution are becoming increasingly serious problems, leading to a growing demand for efficient and convenient drinking water treatment equipment. Direct drinking water machines, as devices that can directly filter and purify tap water into drinkable water, have received widespread attention.

[0003] Traditional water purifiers typically use simple filtration systems that filter tap water through filter cartridges to remove impurities, odors, and some harmful substances. However, this filtration method has certain limitations and its filtration effect is limited. The filter cartridges of traditional water purifiers can often only remove larger particles of impurities and some harmful substances, and are difficult to effectively remove some tiny pollutants, bacteria, viruses, etc. Because there is no circulation system, the water in traditional water purifiers is prone to the growth of bacteria and algae after being left to stand for a long time, leading to a decline in water quality.

[0004] Therefore, it is necessary to redesign a direct drinking water machine with a circulation structure to address the above-mentioned problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a direct drinking water machine with a circulation structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

By setting up devices such as a cleaning device, a water storage tank 9, and a motor 16, the motor 16 can drive the cleaning device to work, so that the cleaning device can clean the impurities on the inner wall of the water storage tank 9, and at the same time, it is easier to clean the water storage tank 9.

[0026] The coarse filtration device includes a filter box 8, and one end of a water inlet pipe 5 is connected to the filter box 8. A filter plate 14 is fixedly installed on the inner wall of the filter box 8.
