Description

Technical Field

[0001] The utility model relates to the technical field of fluid filtration, in particular to a water pool slag baffle, a water pool circulating filtration device and a SPA water pool. Background Art

[0002] With the continuous development of technology and the continuous improvement of the quality of life, people pay more and more attention to their physical health. However, due to the increasing work pressure and life pressure, people often choose various stress reduction methods. Among them, SPA, as a healthy leisure service for relieving stress and relaxing the skin, is favored by more and more people. Through SPA hydrotherapy, people can achieve relaxation in hearing, taste, touch, smell and vision, so as to relieve stress.

[0003] As the main water supply body for SPA hydrotherapy, the quality of the water in the SPA water pool is crucial. Therefore, the prior art usually sets up a water pool circulating filtration system. Water flows from the water pool into the water pool circulating filtration system and then returns to the water pool after being treated by the water pool circulating filtration system. However, the filter element of the water pool circulating filtration system is mainly used to filter fine dirt, and the water inlet of the water pool circulating filtration system is usually set at the bottom of the side wall of the water pool, which cannot handle the slag floating on the water surface of the water pool, such as hair, larger particles of dirt, etc. Therefore, for the slag floating on the water surface of the water pool, manual cleaning is mainly used at present, resulting in increased costs and inconvenience. If the water inlet of the water pool circulating filtration system is set at the height of the water surface of the water pool, although the slag floating on the water surface of the water pool can be removed, the slag will be sucked into the filter of the water pool circulating filtration system, resulting in easy blockage of the filter element of the filter, thus causing the filtration function of the filter to fail, and ultimately causing the water pool circulating filtration system to fail to work properly.

[0041] A slag baffle for a water tank of the present utility model, during application, its housing 1 is installed on the side wall of the water tank 30 and is located outside the water storage cavity 301 of the water tank 30, and the water inlet 11 of the housing 1 is laterally communicated with the water storage cavity 301 of the water tank 30. At the same time, it is ensured that the height range between the upper end and the lower end of the water inlet 11 covers the highest water level line and the lowest water level line of the water tank 30, and the water outlet 12 of the housing 1 is communicated with the water inlet end of the water circulation pipeline. The working principle of the slag baffle for the water tank of the present utility model will be described in detail below.

[0042] Please refer to Figures 1 - 9 As shown, a water tank circulation filtration device of the present utility model includes a water circulation pipeline 8, and also includes the slag baffle for the water tank of the present utility model as described above. The water inlet end of the water circulation pipeline 8 is communicated with the water outlet 12, and the water outlet end of the water circulation pipeline 8 is communicated with the water storage cavity 301 of the water tank 30. A water pump (not shown in the figure) and a filter element (not shown in the figure) are provided on the water circulation pipeline 8. In other embodiments, a filter with a pumping function is provided on the water circulation pipeline.

[0043] In this embodiment, the water inlet end of the water circulation pipeline 8 is connected to a water inlet pipe 4. The water inlet end of the water inlet pipe 4 is connected to the water storage cavity 301 of the water tank 30 and is located below the water surface of the water tank 30, specifically at the bottom of the side wall of the water tank 30. A first filter cover 5 is provided at the water inlet end of the water inlet pipe 4, and a pipe joint 7 is provided at the water outlet end of the water inlet pipe 4 for connecting the water inlet end of the water circulation pipeline 8. A bypass through hole 41 is provided on the side wall of the water inlet pipe 4, and the bypass through hole 41 is connected to the water outlet 12 of the housing 1 through a connecting pipe 6. The water outlet end of the water circulation pipeline 8 is connected to a water outlet pipe 9. The water outlet end of the water outlet pipe 9 is connected to the water storage cavity 301 of the water tank 30 and is located below the water surface of the water tank 30, and a second filter cover 10 is provided at the water outlet end of the water outlet pipe 9.

[0044] The working principle of a water tank circulation filtration device of the present utility model is as follows:

[0045] When the water pump is started, the water in the water tank 30 enters from the water inlet end of the water inlet pipe 4 and the water inlet 11 of the housing 1. Since the height of the water inlet 11 of the housing 1 is near the water level line of the water tank 30, when the water inlet 11 takes in water, the water flow and the slag floating on the water surface of the water tank 30 will flow towards the water inlet 11 together and enter through the water inlet through hole 211 of the filter basket 2. And the water flow drives the water inlet door panel 3 in the filter basket 2 to open, as Figure 8As shown, the water flow and slag are made to enter the filter basket 2 together; after being filtered by the filter basket 2 to block the slag, the relatively clean water flow flows out from the water outlet 12 of the housing 1 and flows along the connecting pipe to the water inlet pipe 4, and together with the water flow entering from the water inlet end of the water inlet pipe 4, it flows to the filter element. After the water flow is further filtered by the filter element, it flows back into the water storage chamber 301 of the water tank 30 through the water outlet pipe 9, realizing water circulation and keeping the water surface of the water tank 30 basically constant. When the water pump stops working, the water inlet 11 of the housing 1 and the water inlet end of the water inlet pipe 4 stop admitting water. At this time, the inlet door plate 3 in the filter basket 2 flips downward and closes by its own gravity, as Figure 7 shown, thus preventing the slag collected in the filter basket 2 from flowing back into the water storage chamber 301 of the water tank 30.

[0046] When it is necessary to clean the slag in the filter basket 2, just pull the disassembly and assembly handle 212 of the filter basket 2, take out the filter basket 2 from the water inlet 11, and then disassemble the water inlet cover 21 and the filter mesh cover 22 of the filter to quickly remove the slag in the filter basket 2.

[0047] Therefore, the utility model can achieve the purpose of automatically cleaning the floating slag in the water tank 30 and prevent the floating slag in the water tank 30 from entering the filter element of the water tank circulation filtration device and blocking the filter element.

[0048] A water tank circulation filtration device of the utility model can be applied to SPA water tanks, but is not limited thereto, and other types of water tanks are also applicable.

[0049] Please refer to Figure 9 shown, a control box of an SPA water tank of the utility model includes the box body 20 of the control box and the water tank circulation filtration device of the utility model as described above.
