The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0032] The water softener has a regeneration state and a water replenishment state. When the water softener is in the regeneration state, the raw water and the salt solution in the salt supply device are mixed to form a regeneration solution, which enters the resin tank through the multi-way valve of the water softener and undergoes a regeneration reaction on the resin in the resin tank, thereby ensuring that the regeneration ions in the resin tank are sufficient; and when the salt solution in the salt supply device has been used for a period of time, it is necessary to replenish the salt solution in the salt supply device. At this time, the water softener is in a soft water state and needs to be supplied with raw water to enter the salt supply device to dissolve more salt in the salt supply device, thereby forming more salt solution for use.

[0033] The regeneration liquid enters the resin tank and undergoes a regeneration reaction with the resin. The principle is: the ions (sodium ions) in the regeneration liquid that play a regeneration role are used to replace the hardness ions (calcium ions, magnesium ions, etc.) adsorbed by the resin. The sodium ions in the absorbed regeneration liquid will exchange with the failed resin particles to restore the softening ability of the resin, and the solution containing calcium and magnesium ions in the exchange will be quickly discharged under the impetus of the gas, thereby achieving regeneration.

[0034] Please refer to Figure 1 In one embodiment, the ejector of the water softener is connected to the salt supply device and the multi-way valve of the water softener respectively. The ejector can guide the liquid from the salt supply device to the multi-way valve and enter the resin tank of the water softener through the multi-way valve; in addition, the ejector can also guide the liquid from the multi-way valve to the salt supply device, thereby replenishing the salt supply device. As for the composition of the liquid guided by the ejector, it is selected according to the state of the water softener.

[0035] Specifically, in conjunction with reference Figure 2 The ejector includes a main body 100, which has a mixing chamber 101 and a water inlet pipeline 110, a salt supply pipeline 120 and a water outlet pipeline 130 connected to the mixing chamber 101. The water outlet pipeline 130 is connected to a multi-way valve, and the salt supply pipeline 120 is connected to a salt supply device. Figure 3 The water softener has at least two regeneration states that can produce regeneration liquid of different concentrations. Figure 4 There are at least two water inlet pipes 110, and the flow areas of different water inlet pipes 110 are different; when the water softener is in one of the regeneration states, a corresponding water inlet pipe 110 can be selectively opened.

[0036] Through the above-mentioned arrangement, by making the flow areas of different water inlet pipes 110 different, different negative pressures can be generated when raw water flows into the water inlet pipe 110, thereby controlling the flow rate of the salt solution in the salt supply pipe 120; after the regeneration state starts, different water inlet pipes 110 can be selectively opened according to the different regeneration liquids required to control the flow rate of the salt solution entering the multi-way valve, thereby mixing with the same amount of raw water and providing regeneration liquids of different concentrations; by opening and closing different water inlet pipes 110, the conversion between different regeneration states can be achieved, thereby controlling the concentration of the regeneration liquid, which is beneficial to improving the utilization rate of the salt solution and improving the regeneration rate.

[0037] It should be noted that when the water softener is in any regeneration state, the raw water flows to the mixing chamber 101 through the water inlet pipe 110 and generates a negative pressure. Under the action of negative pressure, the salt solution enters the mixing chamber 101 through the salt supply device and mixes with the raw water to form a regeneration liquid. The regeneration liquid flows to the multi-way valve through the water outlet pipe 130.

[0038] Preferably, when different regeneration liquids with decreasing concentrations need to be provided to the water softener, the water inlet pipe 110 with a smaller flow area is first opened to absorb more saline solution and mix with the raw water, thereby forming a high-concentration regeneration liquid, which enters the resin tank of the water softener through a multi-way valve for sufficient ion exchange. As the regeneration continues, the ions that need to be exchanged also decrease. At this time, the water inlet pipe 110 with a larger flow area is switched to be opened to absorb less saline solution and mix with the raw water, thereby forming a low-concentration regeneration liquid, which enters the resin tank of the water softener through a multi-way valve. Providing a regeneration liquid with a lower concentration at this stage will not cause salt waste, nor will it hinder the regeneration effect, and is more conducive to improving the utilization rate of the saline solution and the regeneration rate.

[0039] It should be noted that in other embodiments, different regeneration liquids with increasing concentrations may be provided to the water softener, and the water inlet pipe 110 with a larger flow area is opened first to absorb less saline solution and mix with the raw water, thereby forming a low-concentration regeneration liquid. As the regeneration continues, the water inlet pipe 110 with a smaller flow area is opened to absorb more saline solution and mix with the raw water, thereby forming a high-concentration regeneration liquid.

[0040] exist Figure 3 In the illustrated embodiment, each water inlet pipeline 110 includes a functional section 111 for generating negative pressure. The functional section 111 is arranged to be narrowed along the flow direction of raw water, and the functional sections 111 of different water inlet pipelines 110 have different flow areas.

[0041] With this arrangement, the raw water in the water inlet pipe 110 passes through the functional section 111, and the flow area of ​​the functional section 111 at the narrowed position suddenly becomes smaller, so that the flow rate of the raw water suddenly increases to generate a negative pressure effect. Under the action of the negative pressure, the salt solution is sucked into the mixing chamber 101 from the salt supply pipe 120, thereby realizing the siphoning of salt solution by the ejector.

[0042] It should be noted that the functional section 111 is the raw water inlet end. For example, when it is necessary to provide different regeneration liquids with decreasing concentrations to the water softener, the water inlet pipe 110 of the functional section 111 with a smaller flow area is first opened to absorb more salt solution and mix with the raw water, thereby forming a high-concentration regeneration liquid; and as the regeneration continues, the ions that need to be exchanged also decrease, and at this time, the water inlet pipe 110 of the functional section 111 with a larger flow area is switched to be opened to absorb less salt solution and mix with the raw water, thereby forming a low-concentration regeneration liquid.

[0043] For another example, when different regeneration liquids with increasing concentrations need to be provided to the water softener, the water inlet pipe 110 with a smaller flow area is first opened to absorb more salt solution and mix with the raw water, thereby forming a high-concentration regeneration liquid. As the regeneration continues, the water inlet pipe 110 with a larger flow area is switched to be opened to absorb less salt solution and mix with the raw water, thereby forming a low-concentration regeneration liquid.

[0044] Specifically, please refer to Figure 3 and Figure 4 Each functional section 111 includes a first end 111a and a second end 111b that are arranged opposite to each other along the raw water flow direction, and the flow areas of the second ends 111b of the functional sections 111 of different water inlet pipelines 110 are different.

[0045] It should be noted that the flow areas of the first ends 111 a of the functional sections 111 of different water inlet pipes 110 may be the same or different.

[0046] In this way, the flow areas of the first ends 111a of different functional segments 111 are the same to ensure the same amount of raw water inlet, while the flow areas of the second ends 111b of different functional segments 111 are different, that is, different functional segments 111 have different narrowing cross-sections, so that different functional segments 111 can generate different negative pressures.

[0047] It can be understood that the smaller the flow area of ​​the second end 111b of the functional section 111, the greater the negative pressure effect generated; the larger the flow area of ​​the second end 111b of the functional section 111, the smaller the negative pressure effect generated. Different sizes of negative pressure effects are generated by the different flow areas of the second end 111b, so that the amount of salt solution sucked into the salt supply pipeline 120 is different. After the regeneration state starts, different water inlet pipelines 110 can be selectively opened according to the different regeneration liquids required to control the flow of the salt solution entering the multi-way valve, so as to mix with the same amount of raw water and provide different concentrations of regeneration liquid; and when it is necessary to switch the regeneration condition, the regeneration condition is converted by opening and closing different water inlet pipelines 110, thereby controlling the concentration of the regeneration liquid.

[0048] In this embodiment, the ejector further includes nozzles 200 corresponding to the number of water inlet pipes 110, each nozzle 200 is detachably arranged in the functional section 111 of each water inlet pipe 110, and the flow cross section of the nozzle 200 is narrowed along the flow direction of the raw water, and the flow cross sections of the nozzles 200 in different functional sections 111 have different flow areas. In this way, the narrowing setting of the functional section 111 is achieved, and the nozzle 200 is detachably assembled in the functional section 111, which is more convenient for the flexible setting of different flow cross sections. In some other embodiments, the narrowing structure can also be directly cast in the functional section 111, and this application is not limited here.

[0049] Here, please refer to Figure 4 , the flow areas at one end of the nozzles 200 of different water inlet pipes 110 are the same and the flow areas at the other end of the nozzles 200 are different.

[0050] exist Figure 1 In the illustrated embodiment, each water inlet pipeline 110 further includes a jet section 112 , which is located downstream of the second end 111 b of the functional section 111 in the raw water flow direction, and has a flow area greater than that of the functional section 111 .

[0051] With this arrangement, the raw water in the water inlet pipe 110 first flows through the functional section 111 and then flows through the jet section 112, and finally enters the mixing chamber 101; the narrowing arrangement of the functional section 111 generates negative pressure in the jet section 112, so as to draw the saline from the salt supply pipe 120 into the jet section 112 and mix with the raw water before entering the mixing chamber 101.

[0052] Here, the flow area of ​​the jet section 112 is smaller than the flow area of ​​the mixing chamber 101. By providing the jet section 112 with a flow area smaller than that of the mixing chamber 101, negative pressure is generated in the jet section 112, thereby ensuring the effectiveness of the siphon effect.

[0053] In a specific embodiment, the water inlet pipe 110 and the water outlet pipe 130 can be selected from pipes with small apertures, such as capillaries. When the water softener is in a regeneration state, when raw water enters the mixing chamber 101 from the water inlet pipe 110, due to the narrowing effect of the functional section 111, a siphon force is generated on the capillary, and the salt solution can enter the jet section 112 through the salt supply pipe 120 under the action of the siphon force, and the salt solution enters the mixing chamber 101 together with the raw water.

[0054] Specifically, please refer to Figure 4 Each jet section 112 includes a third end 112a and a fourth end 112b which are arranged opposite to each other along the raw water flow direction. The third end 112a of the jet section 112 is connected to the second end 111b of the functional section 111, and the fourth end 112b of the jet section 112 is connected to the mixing chamber 101. With this arrangement, the jet section 112 can be smoothly connected to the functional section 111 and the mixing chamber 101.

[0055] In this embodiment, the ejector further includes throats 300 corresponding to the number of water inlet pipelines 110, and the throats 300 are detachably arranged in the jet section 112 of each water inlet pipeline 110, and the throats 300 are respectively connected to the functional section 111 and the mixing chamber 101, and the flow area of ​​the throats 300 is greater than the flow area of ​​the functional section 111. In this way, the throats 300 are detachably assembled in the jet section 112, which is more convenient for flexible setting of the flow cross section. In some other embodiments, the flow cross section can also be directly cast in the jet section 112, and this application is not limited here.

[0056] Here, since the nozzle 200 is disposed in the functional section 111 , the throat 300 is connected to the nozzle 200 and the mixing chamber 101 respectively, and the flow area of ​​the throat 300 is larger than the flow area of ​​the nozzle 200 .

[0057] exist Figure 2 In the illustrated embodiment, there are at least two water outlet pipes 130, and different water outlet pipes 130 have different flow areas. Through this arrangement, water outlets with different concentrations can be formed for outputting regeneration liquids with different concentrations in the mixing chamber 101.

[0058] For example, the water outlet pipelines 130 and the water inlet pipelines 110 are arranged in a one-to-one correspondence. When one of the water inlet pipelines 110 is opened to form a regeneration liquid with a lower concentration, the corresponding water outlet pipeline 130 is opened for circulating the low-concentration regeneration liquid; when the other water inlet pipeline 110 is opened to form a regeneration liquid with a higher concentration, the corresponding water outlet pipeline 130 is opened for circulating the high-concentration regeneration liquid. In this way, the water outlet pipelines 130 are prevented from overlapping with each other, so as to avoid mutual influence between regeneration liquids with different concentrations.

[0059] In this embodiment, please refer to Figure 3 , all the water inlet pipes 110, the mixing chamber 101 and the water outlet pipes 130 form at least two regeneration flow paths with different flow areas; when the water softener is in different regeneration states, one regeneration flow path can be selected.

[0060] In this way, different flow areas are formed by selectively opening different water inlet pipes 110. The flow rate or concentration of the regeneration liquid flowing through different flow areas is different. According to the requirements of different stages of the regeneration process, different amounts or concentrations of regeneration liquid can be input to better adapt to the dynamic changes of the ion exchange reaction during the regeneration process, reduce salt waste, and achieve good regeneration effects, thereby improving regeneration efficiency.

[0061] For example, when it is necessary to provide different regeneration liquids with decreasing concentrations to the water softener, the water inlet pipeline 110a of the functional section 111 with a smaller flow area is first opened, and the salt supply pipeline 120 absorbs more salt solution to mix with the raw water, and the raw water and salt water entering the mixing chamber 101 are mixed in the mixing chamber 101 to form a high-concentration regeneration liquid, and the regeneration liquid enters the multi-way valve through the water outlet pipeline 130a, thereby forming a regeneration flow channel from the water inlet pipeline 110a, the salt supply pipeline 120, the mixing chamber 101, and the water outlet pipeline 130a;

[0062] As the regeneration continues, the ions that need to be exchanged also decrease. At this time, the water inlet pipe 110b of the functional section 111 with a larger flow area is switched to open, and the salt supply pipe 120 draws in less salt solution to mix with the raw water. The raw water and salt water entering the mixing chamber 101 are mixed in the mixing chamber 101 to form a low-concentration regeneration liquid. The regeneration liquid enters the multi-way valve through the water outlet pipe 130b, thereby forming another regeneration flow channel from the water inlet pipe 110b, the salt supply pipe 120, the mixing chamber 101, and the water outlet pipe 130b.

[0063] In one embodiment, the ejector further includes a switching element (not specifically shown in the figure), which is used to open different water inlet pipes 110 and water outlet pipes 130. By opening and closing different water inlet pipes 110, the amount of raw water entering the mixing chamber 101 is controlled, thereby forming regeneration liquids of different concentrations. By opening and closing different water outlet pipes 130, regeneration liquids of different concentrations and amounts are delivered to the multi-way valve side according to actual needs, thereby realizing automatic regulation.

[0064] Specifically, in some embodiments, the switching element includes a movable valve plate and a fixed valve plate, both of which are provided with flow channel holes, and the movable valve plate can move relative to the fixed valve plate, and the flow channel holes that cooperate and communicate between the movable valve plate and the fixed valve plate are adjusted so that the flow channel holes communicate with different water inlet pipes 110 and water outlet pipes 130. In other embodiments, the switching element can be set to any other structure, which is not limited in this application.

[0065] exist Figure 3 In the illustrated embodiment, the water softener also has a water replenishment state. When the water softener is in the water replenishment state, raw water flows into the mixing chamber 101 through any water outlet pipeline 130 and flows to the salt supply device through the salt supply pipeline 120.

[0066] Specifically, when the water softener is in the water replenishment state, the raw water enters the mixing chamber 101 through the water outlet pipe 130 and then enters the salt supply device from the salt supply pipe 120, forming a water replenishment flow channel from the water outlet pipe 130, the mixing chamber 101, and the salt supply pipe 120. In this way, the regeneration flow channel and the water replenishment flow channel flow in opposite directions and are formed by using the same pipe and sharing the mixing chamber 101.

[0067] exist Figure 4 In the illustrated embodiment, the ejector further includes a filter screen 400, which is detachably disposed on the water outlet pipeline 130. In this way, impurities in the regeneration liquid output from the water outlet pipeline 130 are filtered to prevent the regeneration effect from being affected.

[0068] Please refer to Figure 1 The main body 100 includes a base 102 and a cover 103 , and the base 102 and the cover 103 are detachably connected and surround a mixing chamber 101 .

[0069] In this embodiment, the water inlet pipeline 110, the water outlet pipeline 130 and the salt supply pipeline 120 are all arranged on the base 102. Through the above arrangement, by arranging the main body 100 into two detachable parts, it is convenient to install and disassemble various parts of the ejector.

[0070] Please refer to Figure 1 , a water softener in one embodiment includes the above-mentioned ejector, multi-way valve, resin tank and salt supply device.

[0071] When the water softener is in the regeneration state, the regeneration liquid enters the resin tank through the multi-way valve to regenerate the resin tank; when the water softener is in the water replenishment state, the raw water enters the salt supply device through the ejector to replenish the salt supply device.

[0072] By providing a mixing chamber 101 in the main body 100 of the ejector, the water softener shares the mixing chamber 101 in the regeneration and water replenishment states, avoiding the need to provide multiple different water channels in the water softener, thereby simplifying the structure of the water softener and making the water channel structure of the water softener simple.

[0073] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
