The water softener has a water supply state, a regeneration state and a water replenishing state. When the water softener is in a water supply state, raw water flows to the multi-way valve 20 through the bypass valve 30 and the ejector 10 and enters the resin tank, and hardness ions (calcium ions, magnesium ions and the like) in the raw water are adsorbed by resin in the resin tank, so that the raw water is softened; when the water softener is in a regeneration state, raw water is mixed with salt liquid in the salt supply device to form regeneration liquid, the regeneration liquid enters the resin tank through the multi-way valve 20 of the water softener and performs a regeneration reaction on resin in the resin tank, so that sufficient regeneration ions in the resin tank are ensured; when the salt solution in the salt supply device is used for a period of time, the salt solution in the salt supply device needs to be supplemented, and at the moment, the water softener is in a water supplementing state, raw water needs to be supplied to the salt supply device, more salt in the salt supply device is dissolved, and more salt solution is formed for use.

The regeneration liquid enters the resin tank to carry out regeneration reaction with the resin, and the principle is as follows: the hardness ions (calcium ions, magnesium ions, etc.) adsorbed by the resin are replaced by ions (sodium ions) that exert a regenerating action in the regenerating liquid. Sodium ions in the sucked regeneration liquid can perform exchange reaction with the failed resin particles to recover partial softening capacity of the resin, and the solution containing calcium and magnesium ions under exchange is rapidly discharged under the pushing of gas, so that the regeneration is realized.

Referring to fig. 1, in one embodiment, a jet 10 of a water softener is connected to a salt supply device of the water softener, a multi-way valve 20 of the water softener, and a bypass valve 30 of the water softener, respectively, and the bypass valve 30 is connected to a water supply device for supplying raw water. The ejector 10 is positioned between the bypass valve 30 and the multi-way valve 20, and the ejector 10 can guide the liquid to flow from the salt supply device or the bypass valve 30 to the multi-way valve 20 and enter the resin tank of the water softener through the multi-way valve 20; in addition, the ejector 10 is also capable of directing fluid from the multi-way valve 20 to the salt supply to replenish the salt supply. As regards the composition of the liquid guided by the jet 10, this is chosen according to the state in which the water softener is present.

Specifically, referring to fig. 2 to 4, the jet device 10 includes a main body 100 and a jet assembly 200, the main body 100 includes a first cover 110, a second cover 120, and a third cover 130 detachably connected to each other, the third cover 130 and the first cover 110 are respectively disposed on opposite sides of the second cover 120, one side of the second cover 120 is fastened to the first cover 110 to form a first cavity 101, the other side of the second cover 120 is fastened to the third cover 130 to form a second cavity 102, the second cavity 102 is communicated with the multi-way valve 20, the first cavity 101 is communicated with the bypass valve 30, the first cavity 101 is communicated with the second cavity 102, and the jet assembly 200 is disposed in the second cavity 102.

In the ejector 10, the bypass valve 30 and the multi-way valve 20 are respectively arranged at different sides of the ejector 10, the main body 100 of the ejector 10 is respectively provided with the accommodating cavities communicated with the bypass valve 30 and the multi-way valve 20, the main body 100 of the ejector 10 is of a detachable structure, the bypass valve 30 and the multi-way valve 20 can be prevented from interfering with each other, and the ejector 10 can meet the design requirements of integration and miniaturization.

In this embodiment, the first cover 110, the second cover 120, and the third cover 130 are detachably connected to facilitate quick assembly, disassembly, and maintenance of the ejector 10. For example, the first cover 110 has a first fixing hole, the second cover 120 has a second fixing hole, and the third cover 130 has a third fixing hole, and the first fixing hole, the second fixing hole, and the third fixing hole are formed through a fastening member, which may be a screw or a bolt, to fasten the covers. In other embodiments, the first cover 110, the second cover 120, and the third cover 130 may be an integral structure.

Referring to fig. 3 and 5, the main body 100 has a jet flow channel 140 and a flow channel 150, which are independent from each other, and the flow channel 150 penetrates through the main body 100 and is used for conducting the first cavity 101 and the second cavity 102; a fluidic passage 140 is disposed within the second volume 102 and is selectively in communication with the multiplex valve 20.

Here, the fluidic channel 140 is selectively in communication with the multiplex valve 20, as can be understood: the fluidic channel 140 and the multiplex valve 20 can be in a blocking state or a conducting state.

For example, when the water softener is in a water supply state, the jet flow passage 140 and the multi-way valve 20 are in a blocking state, raw water flows into the resin tank through the bypass valve 30, the overflow passage 150 and the multi-way valve 20 in sequence for softening treatment, then flows to the multi-way valve 20, the overflow passage 150 and the bypass valve 30, and soft water after softening treatment is output by the bypass valve 30; when the water softener is in a regeneration state, the jet flow channel 140 and the multi-way valve 20 are in a conduction state, raw water sequentially flows through the bypass valve 30, the flow channel 150, the multi-way valve 20 and the jet flow channel 140 to generate regeneration liquid, and the regeneration liquid flows into the resin tank through the multi-way valve 20 so as to achieve the purposes of resin cleaning and ion exchange; when the water softener is in a water supplementing state, the jet flow channel 140 and the multi-way valve 20 are in a conducting state, and raw water sequentially flows through the bypass valve 30, the flow channel 150, the multi-way valve 20 and the jet flow channel 140 and flows into the salt supply device, so that enough salt liquid is stored in the salt supply device.

Referring to fig. 6, the jet channel 140 includes a water inlet line 141, a salt supply line 142 and a water outlet line 143, the water outlet line 143 is selectively communicated with the multi-way valve 20, the salt supply line 142 is communicated with a salt supply device of the water softener, and the water inlet line 141 is communicated with the second chamber 102. When the water softener is in a regeneration state, the raw water flows to the water outlet pipeline 143 through the water inlet pipeline 141 and the second cavity 102 and generates a negative pressure effect, the salt liquid enters the water outlet pipeline 143 through the salt supply device under the negative pressure effect and is mixed with the raw water in the water outlet pipeline 143 to form a regeneration liquid, and the regeneration liquid flows to the multi-way valve 20 through the water outlet pipeline 143.

It should be noted that, in the present embodiment, the water inlet line 141 and the water outlet line 143 are located on the same side of the ejector 10. In other embodiments, the water inlet line 141 and the water outlet line 143 may also be located on different sides of the ejector 10.

Specifically, referring to fig. 3 and 4, the water outlet pipe 143 includes a functional section 143a and a jet section 143b, the jet section 143b is located downstream of the functional section 143a in the raw water flowing direction, and the functional section 143a is narrowed in the raw water flowing direction and used for generating a negative pressure.

It should be noted that the functional section 143a is a raw water inlet end. Through the above arrangement, the raw water in the water inlet pipeline 141 passes through the functional section 143a, and the flow area of the functional section 143a at the narrowing position is suddenly reduced, so that the flow rate of the raw water is suddenly increased to generate a negative pressure effect, and the salt solution is sucked into the jet section 143b from the salt supply pipe under the negative pressure effect, thereby realizing the siphon salt solution of the ejector 10.

More specifically, referring to fig. 3 and 4, the functional section 143a includes a first end and a second end opposite to each other along the raw water flowing direction, the flow area of the first end is larger than that of the second end, and the working flow Q = K × Q of the salt supply pipeline 142 is provided ₀ V (3.14 × d/4) + a, where K is the coefficient of variation, d is the diameter of the second end, a is the constant coefficient, Q ₀ Is the operating flow of functional segment 143 a.

It will be appreciated that the operating flow rate of the salt supply line 142 varies linearly with the diameter of the second end. Under the condition of a certain pressure, the working flow of the salt supply pipeline 142 is related to the diameter of the second end of the functional section 143a, and the diameters of the second ends of the different functional sections 143a are adjusted, so that different working flows of the salt supply pipeline 142 and different concentrations of the regeneration liquid of the jet flow section 143b can be obtained, and different resin regeneration requirements can be met.

Referring to fig. 3 and 4, the regeneration liquid concentration β = qa/(Q) of the jet flow section 143b ₀ + Q) where Q is the operating flow rate of the salt supply line 142 and a is the saturated concentration of the salt solution.

Preferably, the saturation concentration a of the salt solution is 26.4%.

Referring to fig. 3 and 4, the regeneration liquid concentration β of the jet section 143b ranges from 5% to 14%.

It can be understood that if the concentration of the regeneration liquid in the jet flow section 143b is too low, the regeneration effect on the resin cannot be achieved; if the concentration of the regeneration liquid in the jet section 143b is too high, the cost will be increased. By controlling the concentration of the regeneration liquid in the jet section 143b, the regeneration effect of the resin can be kept optimal.

Referring to fig. 6, the water softener has at least two regeneration states capable of generating regeneration liquids with different concentrations, at least two water inlet pipes 141, at least two water outlet pipes 143 corresponding to the water inlet pipes 141, and different flow areas of the water outlet pipes 143; all the water inlet pipe 141, the second chamber 102 and the water outlet pipe 143 form at least two regeneration flow passages with different flow areas, and when the water softener is in different regeneration states, one regeneration flow passage can be selected.

In this way, different flow areas are formed by selectively opening different water inlet pipes 141 and water outlet pipes 143. The flow or the concentration of the regeneration liquid that flows through under the different flow area are inequality, can input the regeneration liquid of different volume or different concentration according to the demand of the different stages of regeneration process to the dynamic change of ion exchange reaction in the better adaptation regeneration process reduces the salt extravagant, and regeneration effect is good, can promote regeneration efficiency.

For example, in one embodiment, when different regeneration liquids with different concentrations from large to small are required to be provided to the water softener, the outlet pipe 143 with a smaller flow area is opened to suck more salt liquid to mix with raw water, so as to form a high-concentration regeneration liquid, and the high-concentration regeneration liquid enters the resin tank of the water softener through the multi-way valve 20 for sufficient ion exchange. And along with the continuous going on of regeneration, the ion that needs to carry out the exchange also reduces thereupon, switches to opening the outlet pipe line 143 that has great flow area this moment to inhale less salt solution and raw water mixture, thereby form low concentration regeneration liquid, low concentration regeneration liquid passes through multiple unit valve 20 and gets into in the resin jar of water softener, and it can not cause the salt extravagant to provide the less regeneration liquid of concentration this stage, can not obstruct regeneration effect yet, more is favorable to improving the utilization ratio of salt solution and promotes the regeneration rate.

In other embodiments, different regeneration liquids with different concentrations from small to large may be provided to the water softener, and the water outlet pipe 143 with a larger flow area is opened first to suck less salt liquid to mix with the raw water, thereby forming a low-concentration regeneration liquid. And as the regeneration is continuously carried out, the water outlet pipeline 143 with a smaller flow area is switched to be opened to suck more salt solution to be mixed with the raw water, so as to form high-concentration regeneration solution.

It should be noted that the flow areas of the second ends of the functional sections 143a of the different outlet pipes 143 are different; the flow areas of the first ends of the functional sections 143a of the different outlet conduits 143 may be the same or different. Thus, the same flow area of the first ends of the different functional sections 143a is used to ensure the same water inflow of raw water, while the different flow areas of the second ends of the different functional sections 143a are different, i.e., the different functional sections 143a have different narrowed cross sections, so that the different functional sections 143a can generate different negative pressures. After the regeneration state is started, different water inlet pipelines 141 can be selectively opened according to different required regeneration liquids to control the flow rate of the salt liquid entering the multi-way valve 20, so that the salt liquid is mixed with the same amount of raw water and the regeneration liquids with different concentrations are provided; when the regeneration working condition needs to be switched, the regeneration working condition is switched by opening and closing different water inlet pipelines 141, so that the concentration of the regenerated liquid is controlled.

Referring to fig. 5 and 3, the jet assembly 200 includes a connecting member 210 disposed in the second cavity 102, the connecting member 210 has at least two connecting channels 211, and different connecting channels 211 are respectively communicated with different water inlet pipes 141 and different water outlet pipes 143. Through the arrangement, the inlet and outlet water paths with different concentrations can be formed for inputting and outputting the regeneration liquid with different concentrations in the second cavity 102.

For example, the water outlet pipes 143 are arranged in one-to-one correspondence with the water inlet pipes 141, and when one of the water inlet pipes 141 is opened to form a regeneration liquid with a lower concentration, the water outlet pipe 143 specially used for circulating the regeneration liquid with the lower concentration is correspondingly communicated through the connecting member 210; when another water inlet line 141 is opened to form a high-concentration regeneration liquid, a water outlet line 143 dedicated to circulating the high-concentration regeneration liquid is correspondingly communicated through the connecting piece 210. In this way, the water inlet line 141 and the water outlet line 143 are prevented from overlapping each other, so as to prevent the regeneration liquids of different concentrations from affecting each other.

In this embodiment, the connecting member 210 is detachably fixed in the second cavity 102. For example, the connecting member 210 is fastened to the wall of the second cavity 102 by bolts or screws. In other embodiments, the connecting member 210 may be integrally formed in the second cavity 102.

Referring to fig. 5, the jet assembly 200 further includes nozzles 220 corresponding to the number of the water outlet pipes 143, each nozzle 220 is detachably disposed in the functional section 143a of each water outlet pipe 143, the flow cross section of each nozzle 220 is narrowed along the raw water flow direction, and the flow areas of the flow cross sections of the nozzles 220 of different functional sections 143a are different.

So, realize the narrowing setting of functional section 143a, and nozzle 220 detachable assembles in functional section 143a, the nimble setting of the different circulation cross-sections of being convenient for more. In other embodiments, the narrowing structure may be directly cast in the functional segment 143a, which is not limited herein.

Referring to fig. 5, the flow areas of the nozzles 220 of different outlet pipes 143 are the same and the flow areas of the other ends of the nozzles 220 are different.

Referring to fig. 5, the fluidic assembly 200 further includes a number of throats 230 corresponding to the number of the water outlet pipes 143, each of the throats 230 is detachably disposed in the fluidic section 143b of each of the water outlet pipes 143, the throats 230 are communicated with the functional section 143a, and the flow area of the throats 230 is larger than the flow area of the functional section 143 a.

In this manner, the throat 230 is removably fitted within the jet section 143b, which further facilitates flexible placement of the flow cross-section. In other embodiments, the flow cross-section may be cast directly into the jet section 143b, and the application is not limited thereto.

Here, the nozzle 220 is disposed in the functional section 143a, that is, the throat 230 is communicated with the nozzle 220, and the flow area of the throat 230 is larger than that of the nozzle 220.

Referring to fig. 5, the fluidic assembly 200 further includes a number of filter screens 240 corresponding to the number of the water inlet pipes 141, and each filter screen 240 is detachably disposed in the water inlet pipe 141. Thus, impurities in the liquid output from the water inlet line 141 are filtered to prevent the influence on the regeneration effect.
