Referring to fig. 1 to 3, an exemplary ejector 10 includes a jet member 200, and the jet member 200 is an integrally formed structure. Referring to fig. 4, the jet member 200 is provided therein with a jet section 210 and a throat section 220, the jet section 210 is used for generating negative pressure and is narrowed in the raw water flow direction, and the throat section 220 is located downstream of the jet section 210 in the raw water flow direction.

The ejector 10 and the jet piece 200 are of an integrally formed structure, the injection section 210 and the throat section 220 are arranged on one part, the overlapping of the central axes of the injection section 210 and the throat section 220 and the distance between the central axes are convenient to ensure, the non-concentricity or distance fluctuation error generated by the assembly when the injection section 210 and the throat section 220 are respectively arranged on two different parts is reduced, the resistance of jet flow is ensured to be minimum, and the ejector 10 forms the optimal jet salt absorption effect.

Referring to fig. 4, the spraying section 210 includes a first connection section 211, and the first connection section 211 is narrowed along the raw water flowing direction.

Here, when the raw water flows through the first connection section 211, the narrowing of the first connection section 211 makes the flow rate of the raw water suddenly increase to generate a negative pressure effect, the salt solution enters the throat section 220 through the salt supply device under the negative pressure effect, and the raw water and the salt solution are mixed into the regeneration solution at the throat section 220 and then output.

Specifically, referring to fig. 4, the first connection section 211 has a tapered structure and a taper angle c1 of 12.5 to 14.5 degrees.

Here, the taper angle c1 of the first connection section 211 is an included angle between two generatrices of the first connection section 211. If the taper angle of the first connection section 211 is too large, the narrowing amplitude of the first connection section 211 is too large, so that the negative pressure effect is too large to suck too much salt solution; if the taper angle of the first connection section 211 is too small, the negative pressure effect of the first connection section 211 is not significant, and the salt solution cannot be sucked. Through the setting, the cone angle restriction of first linkage segment 211 is in the optimum scope, enables the negative pressure effect of first linkage segment 211 and is in the best, does benefit to the guarantee and regenerates liquid concentration.

Further, referring to fig. 4, the injection section 210 includes a second connection section 212 connected to the first connection section 211, the second connection section 212 is located between the first connection section 211 and the throat section 220 in the raw water flowing direction, and the second connection section 212 is a straight section.

Here, the second connecting section 212 is a straight section, that is, the diameters of the second connecting section 212 from the beginning to the end are all the same. Through the above arrangement, the raw water sequentially flows through the first connection section 211 and the second connection section 212, the narrowing of the first connection section 211 makes the flow rate of the raw water suddenly increase to generate a negative pressure effect and flow to the second connection section 212, the salt solution enters the throat section 220 through the salt supply device under the negative pressure effect, and the raw water and the salt solution are mixed into the regeneration solution at the throat section 220 and then output.

It should be noted that, in the present embodiment, the diameter of the starting end of the first connection section 211 is larger than the diameter of the end of the first connection section 211, and the diameter of the end of the first connection section 211 is equal to the diameter of the starting end of the second connection section 212. In other embodiments, the diameter of the end of the first connection section 211 may not be equal to the diameter of the start of the second connection section 212.

Referring to fig. 4, the diameter of the second connecting section 212 is d1, and the length L1=0.25 × d1 of the second connecting section 212.

Here, the diameter of the second connection section 212 is the dimension of the second connection section 212 in the X direction shown in fig. 4, and the length of the second connection section 212 is the dimension of the second connection section 212 in the Y direction shown in fig. 4. By limiting the length of the second connection section 212, raw water can smoothly flow from the second connection section 212 to the throat section 220, and the second connection section 212 is prevented from being too long to occupy additional space of the ejector 10.

Referring to fig. 4, the first connection segment 211 includes a first end 211a and a second end 211b that are oppositely disposed along the raw water flowing direction, the throat segment 220 includes a third end 221 and a fourth end 222 that are oppositely disposed along the raw water flowing direction, the third end 221 is communicated with the second end 211b, the distance between the third end 221 and the second end is L2, the diameter of the third end 221 is d2, and L2= (2-3) = d2.

Here, the diameter of the throat section 220 is also the dimension of the throat section 220 in the X direction shown in fig. 4. Therefore, by limiting the distance range between the third end 221 and the second end 211b, the jet effect is affected by too large or too small L2, the best jet effect can be ensured, and the negative pressure peak value of the negative pressure area is in the range.

Referring to fig. 4, the throat section 220 has a tapered structure and a taper angle c2 of 5 to 8 degrees, and the flow area of the third end 221 is smaller than that of the fourth end 222.

Here, the taper angle c2 of the throat section 220 is an included angle between two generatrices of the first connection section 211. Through the arrangement, the throat section 220 is in a horn shape from the third end 221 to the fourth end 222, when the regeneration liquid flows through the throat section 220, the throat section 220 can expand the flow and rapidly output the regeneration liquid, and the diffusion effect of the throat section 220 is optimal.

Referring to fig. 1 to 3, the ejector 10 further includes a main body 100 having a mixing chamber 101 and a water outlet pipe 104 communicating with the mixing chamber 101, and the jet member 200 is disposed in the water outlet pipe 104.

It should be noted that the injection section 210 is a raw water inlet end, when the ejector 10 is in a regeneration state, the raw water flows to the injection section 210 through the mixing chamber 101, the flow area of the injection section 210 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, the salt solution enters the throat section 220 through the salt supply device under the negative pressure effect and is mixed with the raw water to form a regeneration solution, and the regeneration solution flows to the multi-way valve 20 through the throat section 220.

In this embodiment, the fluidic member 200 is removably disposed within the water outlet conduit 104. Thus, the replacement and quick assembly and disassembly of the jet piece 200 and the main body 100 can be facilitated. For example, the fluidic member 200 may be secured to the outlet conduit 104 by a snap-fit or snap-fit arrangement.

Referring to fig. 6, the number of the water outlet pipes 104 is at least two, at least one jet member 200 is disposed in each water outlet pipe 104, all the jet members 200 are connected as a whole, and the flow areas of the jetting sections 210 of the jet members 200 in different water outlet pipes 104 are different.

In this way, all the fluidic members 200 and the main body 100 can be easily and quickly assembled and disassembled, and different flow areas can be formed by selectively opening different water outlet pipelines 104. The flow or the concentration of the regeneration liquid that flow 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 salt extravagant, and regeneration effect is good, can promote regeneration efficiency.

For example, in one embodiment, when different regeneration liquids with different concentrations are required to be supplied to the water softener, the outlet pipe 104 with a smaller flow area is opened to suck more salt liquid to mix with the 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. Along with the continuous proceeding of regeneration, the ions to be exchanged are reduced, at the moment, the water outlet pipeline 104 with a larger flow area is switched to be opened to suck less salt liquid to be mixed with raw water, so that low-concentration regeneration liquid is formed, the low-concentration regeneration liquid enters the resin tank of the water softener through the multi-way valve 20, the regeneration liquid with a smaller concentration is provided in the stage, salt waste cannot be caused, the regeneration effect cannot be hindered, and the salt liquid utilization rate and the regeneration rate can be improved.

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 104 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 104 with a smaller flow area is switched to be opened to suck more salt solution to be mixed with the raw water, so that high-concentration regeneration solution is formed.

It should be noted that, referring to fig. 4-6, the flow areas of the second ends 211b of the injection sections 210 of different water outlet pipes 104 are different; the flow areas of the first ends 211a of the injection sections 210 of different outlet conduits 104 may be the same or different. In this way, the same flow area of the first ends 211a of the different injection sections 210 is used to ensure the same water inflow of raw water, while the different flow areas of the second ends 211b of the different injection sections 210 are different, i.e. the different injection sections 210 have different narrowing cross sections, so that the different injection sections 210 can generate different negative pressures. After the regeneration state begins, different water outlet pipelines 104 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 outlet pipelines 104, so that the concentration of the regeneration liquid is controlled.

In this embodiment, all the fluidic pieces 200 can be integrally formed through injection molding, that is, all the fluidic pieces 200 are connected into a whole, and only once all the fluidic pieces 200 are assembled in the main body 100, so that the assembling efficiency can be improved.

Referring to fig. 5, the ejector 10 further includes a sealing member 400, and the sealing member 400 is sandwiched between the outer wall of the jet member 200 and the inner wall of the water outlet pipe 104. In this way, the sealing between the outer wall of the jet member 200 and the inner wall of the outlet conduit 104 can be improved.

In this embodiment, the seal 400 is an annular seal ring. In other embodiments, the seal 400 may also be a seal structure of other shapes.

In this embodiment, the number of the sealing members 400 is not limited to one, that is, the number of the sealing members 400 may be at least two, and all the sealing members 400 may be clamped between the outer wall of the jet member 200 and the inner wall of the water outlet pipe 104 in the same direction.

Further, referring to fig. 2, 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, and the other side of the second cover 120 is fastened with the third cover 130 to form the mixing chamber 101.

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 the fastening member 140 to fasten the covers, and the fastening member 140 may be a screw or a bolt. In other embodiments, the first cover 110, the second cover 120, and the third cover 130 may be an integral structure.

Referring to fig. 1, a water softener in one embodiment includes the above-described ejector 10.

Specifically, the water softener further comprises a bypass valve 30, a multi-way valve 20, a resin tank and a salt supply device. The ejector 10 further has a water inlet line 102 and a salt supply line 103 which are communicated with the mixing chamber 101, the water outlet line 104 is communicated with the multi-way valve 20, the salt supply line 103 is communicated with the salt supply device, and the water inlet line 102 is communicated with the bypass valve 30.

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.

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, and the regeneration liquid enters the resin tank through the multi-way valve 20 of the water softener to carry out 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 therefore 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 absorbed 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.

Further, referring to fig. 2, the water softener has at least two regeneration states capable of generating regeneration liquids with different concentrations, the water inlet pipeline 102 and the water outlet pipeline 104 are at least two and are arranged in a one-to-one correspondence, and the flow areas of the second ends 211b of the injection sections 210 of different water outlet pipelines 104 are different.

In this embodiment, the water inlet line 102 and the water outlet line 104 are located on the same side of the ejector 10. In other embodiments, the water inlet line 102 and the water outlet line 104 may also be located on different sides of the ejector 10.

Referring to fig. 5 and 2, the ejector 10 of the water softener further includes a connecting member 300, the connecting member 300 has at least two independently disposed connecting pipes 301, and each connecting pipe 301 respectively connects one water inlet pipe 102 and one water outlet pipe 104 corresponding thereto. Through this setting, can form the business turn over water route of different concentrations to supply the regeneration liquid input and output of different concentrations to use in mixing chamber 101.

For example, when one of the water inlet pipes 102 is opened to form a regeneration liquid with a lower concentration, the water outlet pipe 104 specially used for circulating the regeneration liquid with a lower concentration is correspondingly opened through the connecting piece 300; when another water inlet pipeline 102 is opened to form the regeneration liquid with higher concentration, the water outlet pipeline 104 specially used for circulating the regeneration liquid with higher concentration is correspondingly communicated through the connecting piece 300. In this way, the water inlet line 102 and the water outlet line 104 are prevented from overlapping each other, so as to avoid the mutual influence between the regeneration liquids with different concentrations.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
