Description

Technical Field

[0001] The utility model relates to an ejector structure that is resistant to fouling and blocking, and is used in the setting of a resin filter element structure. Background Art

[0002] Because the filter media in water softeners is resin, it requires specialized soft water brine for regeneration. Current water softeners typically use an ejector to absorb brine. However, the water inlet and brine absorption holes in existing ejector structures are very small, making them easily clogged by impurities. When clogged, these impurities cannot be absorbed, causing the brine absorption function to fail and shortening the life of the resin filter element. Summary of the Invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0020] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0021] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0022] Referring to the drawings in the specification, an anti-fouling and clogging ejector structure includes an inlet pipe 10, a main body 20 and an outlet pipe 30 arranged in sequence along the direction of water flow. The outlet pipe can receive mixed brine. An ejector 40 is provided in the main body. An opening 41 for salt inlet is provided on the peripheral side of the ejector. A mesh body 50 is provided on the outer periphery of the opening. The mesh body can be used to block impurities. The main body is also connected to a pipe 60 for conveying salt. The ejector includes an inlet chamber 42 and an outlet chamber 43. The inlet chamber can be connected to the inlet pipe, and the outlet chamber can be connected to the outlet pipe. The opening is provided between the inlet chamber and the outlet chamber. The water flow flowing from the inlet chamber into the outlet chamber can suck the salt in the pipe from the opening and then flow out from the outlet pipe.

[0023] Preferably, the aperture within the water inlet chamber can gradually decrease along the direction of water flow, with the aperture at the water outlet end of the water inlet chamber being the smallest. As water flows from the water inlet chamber into the water outlet chamber, the aperture gradually decreases, creating a negative pressure that draws salt through the opening, where it mixes with the water and flows into the resin filter element. The aperture within the water outlet chamber can gradually increase along the direction of water flow, with the aperture at the water inlet end of the water outlet chamber being the smallest, facilitating the fusion of salt and water. The minimum aperture of the water outlet chamber is larger than the minimum aperture of the water inlet chamber, allowing water to enter the water chamber and be ejected into the water outlet chamber.

[0024] Furthermore, the ejector is provided with an annular groove 44 on its outer periphery, communicating with the opening. The mesh body is annular and disposed within the annular groove. Seal rings 45 are provided at each axial end of the annular groove. These seal rings engage the inner circumferential wall of the main body, ensuring a single direction of water flow. The connection between the pipe and the main body is located between the two seal rings. The top of the annular groove is flush with the outlet end of the water inlet chamber.

[0025] Furthermore, it also includes a box 70 for storing salt, and the box can be connected to the main body through a pipeline.

[0026] More specifically, the ejector utilizes the Bernoulli principle. The front end is the raw water inlet, while the central channel narrows, creating negative pressure to absorb salt water. The outlet is a mixed flow of water that enters the resin tank. Because the ejector's central channel is narrow and easily clogged by impurities, rendering the salt absorption function ineffective, a layer of stainless steel mesh is added around the opening at the waist of the ejector to intercept impurities.

[0027] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
