Background

The water purifier filters harmful substances in raw water through multiple times of filtration to form pure water for drinking. In the process of producing water, water on the raw water side of the filtration membrane permeates to the pure water side due to the presence of pressure, so that concentrated water is formed on the raw water side and pure water is formed on the pure water side. When the water making process is stopped, the pressure is removed, and the ions on the two sides of the filtering membrane gradually permeate to enable the two sides to be balanced. Therefore, when drinking water again after stopping for a period of time, the TDS (Total dissolved solids) value in the water on the pure water side is actually higher, and the drinking is not healthy. Based on this, carry out the mode of diluting through increasing the water tank in the purifier, perhaps set up in the center tube and cut off the mode that reduces TDS infiltration and reduce the start drinking water once more, the concentration of few first aquatic TDS of cup.

As shown in fig. 1, in one embodiment, a water purification assembly 10 is provided, which includes a central tube 11, a water inlet end 114 of the central tube 11 is provided with a one-way water passing assembly 12, a water outlet of the one-way water passing assembly 12 faces into the central tube 11, so that pure water can only flow into the central tube 11 through the one-way water passing assembly 12, and pure water in the central tube 11 cannot flow out through the one-way water passing assembly 12. The one-way water passing assembly 12 is arranged at the water inlet end 114 of the central pipe 11, so that the cavity in the central pipe 11 can be used as a water storage space for pure water.

Specifically, the one-way water passing assembly 12 described herein may be a one-way valve or other assembly capable of performing a one-way water passing function.

The outer wall of center tube 11 is equipped with recess 111, the lateral wall of recess 111 can with the cover establish form the pure water runner between the filtration membrane 20 on the center tube 11. A water delivery passage 112 is arranged on the pipe wall of the central pipe 11, and the water delivery passage 112 is communicated between the pure water flow channel and the water inlet of the one-way water passing assembly 12.

As shown in fig. 1, in the process of producing water, raw water enters from one end of the filtering membrane 20 and flows to the other end, and in the process of flowing, pure water filtered by the filtering membrane 20 firstly enters the pure water flow channel and the water delivery passage 112, and then enters the central tube 11 through the one-way water passing assembly 12, and finally the pure water can flow out through the water outlet end 115 of the central tube 11 for a user to use. In a shutdown state, the one-way water passing assembly 12 separates the water delivery passage 112 from the inner cavity of the central tube 11, so that TDS ions on the concentrated water side of the filtering membrane 20 can only permeate into the pure water flow passage with a small space and the water delivery passage 112, and the pure water in the central tube 11 cannot be polluted. Moreover, the unidirectional water passing assembly 12 is positioned at the water inlet end 114 of the central tube 11, and the water outlet of the unidirectional water passing assembly 12 faces the inside of the central tube 11, so that the capacity of the central tube 11 for storing pure water is greatly improved. When the water is reused after the shutdown, a small amount of water is stored in the pure water flow channel and the water delivery passage 112, and the water permeated with a certain concentration of TDS can be diluted by a large amount of pure water in the central tube 11, so that the concentration of TDS in the first cups of water is effectively reduced when the water is restarted. Moreover, the pure water flow channel and the water delivery passage 112 are arranged in the pipe wall of the central pipe 11, and the one-way water passing assembly 12 is arranged in the central pipe 11, so that the overall structural size is effectively reduced.

Further, by arranging the groove 111 on the outer wall of the central tube 11, on one hand, the overall structural size is reduced, and on the other hand, the depth of the groove 111 is limited, so that the water containing capacity of the pure water flow channel is controlled, and the amount of water to be neutralized and diluted with the pure water in the central tube 11 is reduced.

Specifically, as shown in fig. 1 and 2, the groove 111 may be a strip-shaped groove disposed on the outer wall of the central tube 11, and the strip-shaped groove is disposed along the axial direction of the central tube 11.

Alternatively, the groove 111 may be an annular groove surrounding the outer wall of the central tube 11, or the groove 111 may be a groove with other shapes, which is not limited herein. The groove 111 is set to be the strip-shaped groove, so that the water containing capacity of the groove can be effectively reduced, and meanwhile, the wall thickness of the central tube 11 cannot be greatly influenced, and the overall structure size is simplified. The smaller the capacity, the less water will eventually need to be neutralized and diluted with pure water in the central tube 11.

Further, when the groove is the ring groove, the length of the ring groove in the axial direction of the central tube 11 is slightly smaller than the length of the filtering membrane 20 in the axial direction, so that the water producing capacity of the filtering membrane 20 is fully utilized, and the efficiency of generating pure water is improved.

Specifically, in one embodiment, the strip-shaped groove is a plurality of grooves, and the plurality of grooves are distributed at intervals in the circumferential direction of the central tube 11. Having balanced on the whole filtration membrane 20 produce water ability with the appearance water ability of pure water runner, if the bar groove is too few, then do not make full use of filtration membrane 20's produce water ability, if the bar groove is too much, then the appearance water volume of pure water runner is too big, needs when shutting down after reuse the water that the pure water carries out the dilution in the center tube 11 is too much, will be unfavorable for reducing several preceding aquatic TDS concentrations of TDS. And form protruding muscle between two bar grooves that the interval set up, protruding muscle can be for filtration membrane 20 provides the support.

Of course, alternatively, when the groove is the ring groove, a plurality of supporting pillars matching with the depth of the ring groove may be disposed in the ring groove for supporting the filtering membrane 20 sleeved on the central tube 11.
