Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more particularly to a water circuit controller capable of controlling the switching of two filter cartridges in a water treatment system to a series or parallel connection. This utility model further relates to a water circuit control valve and a water treatment system. Background Technology

[0002] With increasing emphasis on health and concerns about water pollution, water treatment machines or systems have become common household appliances. Water treatment machines, especially household ones such as central water purifiers and water softeners, are often installed in kitchens to treat water and obtain cleaner water.

[0003] To obtain sufficiently clean water or water that meets specific requirements, such as water suitable for direct drinking, existing water treatment systems often have more than one filter cartridge. However, most domestic water treatment systems are installed under the kitchen countertop and are relatively small (larger water treatment systems are difficult to install under the countertop). To improve water treatment efficiency, small water treatment systems are generally equipped with two filter cartridges to increase the number of filter cartridges while maintaining the height of the water treatment system, thereby improving water treatment effectiveness. For example, many water purifiers are equipped with two purification filter cartridges to perform multi-stage purification of raw water or increase the volume of purified water. In addition, small water softeners have less softening resin and are less effective. To improve softening efficiency, small water softeners are also generally equipped with two softening filter cartridges to increase the amount of softening resin while maintaining the height of the water softener. For water softeners with dual softening filters, a series structure can increase the layer height of the softening resin, thereby improving the softening effect, while a parallel structure can increase the water flow. Generally, in areas with high-hardness raw water, a series structure water softener is suitable. In multi-person households, where multiple shower devices are installed, the requirement for soft water flow is relatively high, making a parallel structure water softener more suitable.

[0004] However, existing water circuit controllers in water treatment systems often only allow control over the connection status of a single filter cartridge. For example, some water treatment machines can only control two filter cartridges connected in series or in parallel. This causes inconvenience for users. Utility Model Content

[0005] The main purpose of this invention is to provide a water circuit controller for a water treatment system, wherein the water circuit controller can control the switching between two filter cartridges of the water treatment system in series or in parallel.

The first channel is connected to the second opening and the third opening to form a first connecting channel; the second channel is connected to the second opening and the third opening to form a second connecting channel; the third channel is connected to the fourth opening and the sixth opening to form a third connecting channel.

Figures 4A to 8B As shown, in the embodiment of the present invention, the first end opening 12021 and the second end opening 12022 of the second channel 1202 of the valve core 12 of the water control valve 10 of the water control controller are respectively formed at both ends of the main body 121 of the valve core 12, and the first end opening 12021 and the second end opening 12022 are respectively formed on two opposite sides of the main body 121 of the valve core 12.

[0046] As shown in the attached image. Figures 4A to 8BAs shown, the water circuit control valve 10 of the water circuit controller according to an embodiment of the present invention further includes an operating end 123, wherein the operating end 123 is disposed on the valve core 12, so that an operator can rotate the valve core 12 through the operating end 123. More specifically, the operating end 123 extends from one end of the main body portion 121 of the valve core 12 to allow the user to rotate the valve core 12. Preferably, the water circuit control valve 10 further includes a stop end 124 fixedly disposed on the valve core 12, and the valve body 11 further includes a positioning end 111, wherein the positioning end 111 of the valve body 11 is configured to prevent the stop end 124 from being further rotated, thereby preventing the valve core 12 from being over-rotated, so that the valve core 12 cannot be accurately rotated to the corresponding working position, and thus cannot accurately achieve function switching.

[0047] As shown in the attached image. Figures 4A to 8B As shown, preferably, in the embodiment of the present invention, the valve body 11 of the water circuit control valve 10 of the water circuit controller is a hollow cylindrical shape, and the valve core 12 is a rod shape. The valve core 12 is configured to rotate relative to the valve body 11 in a direction tangential to the extension direction of the valve cavity 110 of the valve body 11 (or longitudinally), thereby switching the water circuit control valve 10 to the series working position and the parallel working position.
