[0035] Water softening equipment is a device that uses cation exchange resin to remove calcium and magnesium ions in water, reduce the hardness of raw water, and thus soften hard water. Water softening equipment is currently widely used in industrial and energy systems and has strong equipment attributes. In household use, the soft water produced by water softening equipment usually has the functions of reducing scale in water heaters, wall-mounted boilers, electric water heaters and other water heating equipment and bathrooms, avoiding pipe blockage, reducing the attenuation of heat exchange efficiency of heating equipment, reducing the use of detergents, being more friendly to human skin, and making clothes softer and brighter in color after washing.

[0036] like Figure 1 and Figure 2 As shown, the present invention provides an ejector 100, including a housing 110. It should be noted that the ejector 100 provided by the present invention is arranged in a water softening device, and is used to mix tap water and salt water to produce salt water of different concentrations, and the salt water can be used for resin regeneration.

[0037] Specifically, Figure 1 and Figure 2As shown, the housing 110 has a main channel 111, a guide channel 112 and a mixing channel 113. The main channel 111 has a first constricted portion 116, and in the direction of water flow, the diameter of the main channel 111 gradually decreases. The narrowest end of the main channel 111 is connected to the guide channel 112. Tap water flows in from the main channel 111 and accelerates in the main channel 111, reaching a maximum speed at the narrowest end of the main channel 111. According to Bernoulli's principle, an increase in fluid velocity will lead to a decrease in the pressure of the surrounding fluid. Therefore, the low pressure formed by the tap water jet will press the salt water from the guide channel 112 into the tap water jet, thereby achieving mixing. The mixing channel 113 has a second constricted portion 117, and in the direction of water flow, the narrowest end of the mixing channel 113 is connected to the narrowest end of the main channel 111 and the guide channel 112. Therefore, the mixed water formed by mixing salt water and tap water will enter the mixing channel 113, and the diameter of the mixing channel 113 will gradually increase, thereby increasing the flow rate of the mixed water.

[0038] Among them, the narrowest end diameter of the main channel 111 is D1, the narrowest end diameter of the mixing channel 113 is D2, and the value range of D1 is between 0.7mm-0.9mm. For example, D1 can be 0.8mm. Within this range, the ejector 100 is under low water pressure conditions of 0.08MPa-0.1MPa of external water pressure. The negative pressure formed by the tap water jet can still smoothly absorb salt water.

[0039] According to the ejector 100 of the embodiment of the utility model, by setting the range of the narrowest end D1 of the main channel 111 to be between 0.7mm and 0.9mm, the ejector 100 can still smoothly absorb salt water under the low water pressure condition of 0.08MPa-0.1MPa under the negative pressure formed by the tap water jet, thereby meeting the requirement that the ejector 100 can still work normally under low water pressure conditions. In this way, the ejector 100 can be used in a wider range of environments and can still be used in environments with insufficient water pressure or water shortage.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment of the utility model, D2 is greater than D1, so that the tap water jet can be prevented from being unable to completely enter the mixing channel 113, and the tap water jet can be prevented from being restricted when entering the mixing channel 113 from the main channel 111, and the tap water flow can be prevented from being blocked, thereby ensuring that the tap water and salt water can flow and mix more effectively, optimizing the dynamic performance of the fluid, and improving the working efficiency of the entire ejector 100 system.

[0041] like Figure 1 and Figure 2As shown, in one embodiment of the utility model, the ratio of D2 to D1 ranges from 1.4 to 1.7. That is, by changing the diameter ratio between the main channel 111 and the mixing channel 113, the negative pressure absorption capacity generated by the tap water jet can be floated, so that the concentration of the mixed salt water is stabilized within a preset fixed range. If the concentration of the salt water is too high, it may cause corrosion to the equipment and affect the service life of the equipment. If the concentration of the salt water is too low, the regeneration ability of the resin may be weakened. Therefore, stabilizing the concentration of the mixed salt water within a preset fixed range can ensure the good use of the soft water equipment.

[0042] like Figure 1 As shown, in another embodiment of the utility model, based on the ratio range of D2 and D1 being 1.4-1.7, at the same time, the opening angle of the main channel 111 is A1, the opening angle of the mixing channel 113 is A2, and the ratio range of A2 and A1 is 1-1.3, so that the negative pressure absorption capacity generated by the tap water jet can float, thereby stabilizing the concentration of the mixed salt water within a fixed range.

[0043] like Figure 1 As shown, on the basis of the above, the diameter of the guide channel 112 is L0, where 1≦L0 / (D1+D2)≦1.5, so that the negative pressure absorption capacity generated by the tap water jet can float, thereby stabilizing the concentration of the mixed salt water at 5%-10%. For example, the ratio of D2 to D1 can be 1.5, the ratio of A2 to A1 can be 1.2, and L0 / (D1+D2) can be 1.1, so that the concentration of the mixed salt water is maintained between 5%-10%.

[0044] like Figure 1 As shown, in one embodiment of the present invention, the guide channel 112 is a guide hole provided on the housing 110, and the guide hole is helpful to accelerate the flow rate of the salt water, so that the salt water can be more easily pressed into the tap water jet.

[0045] like Figure 1As shown, in one embodiment of the utility model, there are multiple guide holes, and the multiple guide holes are spaced apart along the circumferential direction of the shell 110. In this way, by evenly distributing the multiple guide holes around the shell 110, the surface area of ​​the brine in contact with the tap water is increased, and a more even distribution of the brine in the tap water jet can be achieved. Such uniform distribution helps to improve the mixing effect and ensure that the liquid has a consistent concentration and properties throughout the flow process. In addition, the multiple guide holes provide multiple flow channels, which can process a larger volume of brine in a fixed time and increase the flow rate of the mixed solution. If a certain guide hole is blocked or fails, the ejector 100 still has other guide holes that can continue to work, which improves the reliability of the entire ejector 100. In addition, according to actual needs, certain guide holes can be selected to be opened or closed, so as to adjust the flow rate and flow rate to adapt to different operating conditions.

[0046] like Figure 1 As shown, in one embodiment of the utility model, a sealing groove 114 is provided on the outer surface of the housing 110, and a sealing ring 115 is provided in the sealing groove 114. It should be noted that the ejector 100 of the utility model is placed in a pipeline, and the pipeline is divided into two spaces. Tap water enters one end of the pipeline, and the ejector 100 is mixed with salt water to form a mixed salt water solution, which is ejected from the other end of the pipeline. The sealing ring 115 can make the ejector 100 and the pipeline fit tightly, improve the sealing effect between the ejector 100 housing 110 and the pipeline, and prevent the phenomenon of tap water and mixed water mixing in the pipeline where the ejector 100 is located, thereby affecting the concentration of the mixed salt water.

[0047] like Figure 1 As shown, in one embodiment of the present invention, there are multiple sealing grooves 114, and the multiple sealing grooves 114 are arranged along the length direction of the housing 110, and a sealing ring 115 is disposed in at least one sealing groove 114. In this way, the sealing effect between the ejector 100 and the pipeline can be further increased.

[0048] The utility model also proposes a water softening device, including the above-mentioned ejector 100, a salt box, a water channel component and a tank assembly. The salt box is connected to the guide channel 112 to provide salt water for the guide channel 112. The water channel component is connected to the mixing channel 113, and the tank assembly is connected and connected to the water channel component. The tank assembly is equipped with a resin layer for softening tap water. When the resin layer needs to be regenerated, the mixed salt water solution in the ejector 100 enters the water channel component and is guided by the water channel component to the tank assembly, so that the mixed salt water solution can contact the resin layer to regenerate the resin layer.

[0049] The water softening device according to the embodiment of the utility model includes the ejector 100 mentioned above, and thus also has the beneficial effects of the ejector 100 mentioned above, which will not be described in detail here.

[0050] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
