Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to a salt absorption mechanism, a salt box and a water softening device. Background Art

[0002] A water softener is a water purification device that reduces the hardness of water and improves the taste and feel of water. Existing water softeners are mainly divided into two types according to the water purification principle: the first type is a water softener that uses ion exchange method, which mainly removes calcium ions and magnesium ions in water through ion exchange resin; the second type is a water softener that uses physical packaging method, which mainly uses nanocrystalline high-energy polymer spheres to package calcium ions, magnesium ions, bicarbonate, etc. in the water to produce water-insoluble nano-crystals, thereby inhibiting the formation of scale.

[0003] For water softeners using the ion exchange method, the salt tank is an indispensable component for the desalination step. In the water softening equipment in the prior art, the water inlet pipe is connected to the resin tank through a control valve. The water softened and purified by the resin tank is connected to the external drinking water pipe through the water outlet pipe under the action of the control valve. At the same time, the water inlet pipe is also connected to the salt tank through the regeneration pipe of the control valve. The end of the regeneration pipe is provided with a salt absorption mechanism. The salt water is injected into the resin tank through the regeneration pipe by the salt absorption mechanism to regenerate the resin. The salt absorption mechanism is both the outlet for the dissolved salt and the inlet for the salt water to be injected into the resin tank. The salt absorption mechanism in the related art includes a salt absorption pipe, a valve body connected to the bottom of the salt absorption pipe, and a float arranged on the circumference of the valve body. The float can rise and fall with the rise and fall of the liquid level to seal or separate the valve body from the inner bottom wall of the tank, thereby closing or opening the salt absorption port. With the above arrangement, after the injection of brine is completed, the valve body remains sealed with the bottom wall of the box under the action of the gravity of the float. When the pressure of the float on the valve body in the circumferential direction is uneven, it is easy to cause the valve body to be loosely sealed with the bottom wall of the box, thereby affecting the performance of the softening equipment and the water quality.

[0004] Therefore, it is urgent to propose a salt absorption mechanism to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of the present invention is to provide a salt suction mechanism, a salt box and a water softening device, which can avoid the situation where the salt suction port is not sealed tightly after the brine injection work is completed, thereby ensuring that the water softening device has good performance and water quality.

[0020] A resin tank containing resin;

[0021] As described above, the salt tank, the salt absorbing mechanism is communicated with the resin tank, and the salt absorbing mechanism can extract the salt water in the tank body to inject it into the resin tank.

[0022] The beneficial effects of the utility model are:

[0023] The salt absorption mechanism provided by the present invention can, when brine needs to be injected into the resin tank, first inject water into the tank body to dissolve the salt in the tank body to form brine.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0040] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or 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 the specific circumstances.

[0041] 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.

[0042] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0043] This embodiment provides a water softening device, which includes a resin tank and a salt box. The resin tank is filled with resin. The salt box includes a box body and a salt absorption mechanism arranged in the box body. The salt absorption mechanism is connected to the resin tank and can extract salt water in the box body to inject it into the resin tank for resin regeneration.

[0044] The salt absorption mechanism in the related art includes a salt absorption tube, a valve body connected to the bottom of the salt absorption tube, and a float arranged around the valve body. The float can rise and fall with the rise and fall of the liquid level to seal or separate the valve body from the inner bottom wall of the tank, thereby closing or opening the salt absorption port. With this arrangement, after the salt water injection is completed, the valve body remains sealed to the inner bottom wall of the tank under the weight of the float. If the pressure exerted on the valve body by the float around the valve body is uneven, it can easily lead to a loose seal between the valve body and the inner bottom wall of the tank, thereby affecting the performance of the water softener and the water quality.

[0045] In order to solve the above problems, this embodiment further provides a salt absorption mechanism, and the specific structure of the salt absorption mechanism is described in detail below with reference to the accompanying drawings.

[0046] Figure 1 The figure shows a schematic structural diagram of the salt absorption mechanism provided in this embodiment. Figure 2 A cross-sectional schematic diagram of the salt absorption mechanism provided in this embodiment is shown. Figure 3 A schematic diagram of the explosion structure of the salt absorption mechanism provided in this embodiment is shown. Figure 4 FIG. 1 shows a structural diagram of the sealing floating member 300 provided in this embodiment. Figure 5 FIG. 4 shows a cross-sectional view of the sealing floating member 300 provided in this embodiment. Figure 1-Figure 5 As shown, the salt absorption mechanism provided in this embodiment includes a water-passing bracket 100 and a sealing float 300. A water-passing channel 101 is provided in the water-passing bracket 100. A first sealing surface 103 is provided at the bottom of the water-passing bracket 100. The first sealing surface 103 is gradually inclined from top to bottom in a direction away from the axis of the water-passing channel 101. A salt absorption port 102 connected to the water-passing channel 101 is provided on the first sealing surface 103; the sealing float 300 is slidably sleeved on the outside of the water-passing bracket 100, and a second sealing surface 301 cooperating with the first sealing surface 103 is provided on the sealing float 300. The sealing float 300 can rise and fall with the rise and fall of the liquid level, so that the second sealing surface 301 is lifted away from or blocks the first sealing surface 103, so as to selectively open or block the salt absorption port 102.

[0047] The salt absorption mechanism provided in this embodiment can first inject water into the resin tank to dissolve the salt in the tank, forming salt water. As the amount of water injected increases, the second sealing surface 301 on the sealing float 300 lifts away from the first sealing surface 103, thereby opening the salt absorption port 102 and allowing the salt water to flow into the resin tank through the salt absorption port 102 and the water passage 101. During the salt water injection process, as the salt water gradually decreases, the sealing float 300 descends with the liquid level until the second sealing surface 301 covers the first sealing surface 103, thereby blocking the salt absorption port 102 and completing the salt water injection. By providing the first sealing surface 103 and the second sealing surface 301 on the water passage bracket 100 and the sealing float 300, respectively, which can seal against each other and form an inclined surface-to-inclined contact, the sealing float 300, under the action of its own weight or suction, can press against and seal the salt absorption port 102, thereby ensuring the performance and water quality of the water softening device.

[0048] like Figure 2As shown, a seal 110 is provided on the first sealing surface 103, and a communication port is provided on the seal 110 corresponding to the salt intake port 102. The provision of the seal 110 can further enhance the sealing effect between the first sealing surface 103 and the second sealing surface 301. Furthermore, a snap-fitting groove 1031 is provided on the first sealing surface 103, and a snap-fitting hook 111 is provided on the seal 110 to snap-fit ​​with the snap-fitting groove 1031. The snap-fitting groove 1031 and the snap-fitting hook 111 ensure the stability of the connection between the seal 110 and the water-passing bracket 100.

[0049] Optionally, the seal 110 is formed on the first sealing surface 103 using a double-shot soft-glue coating process. The double-shot soft-glue coating process has the advantages of fewer production steps, lower processing costs, and environmental protection, and can make the seal 110 and the water-passing bracket 100 have a better fitting effect.

[0050] Figure 6 FIG. 1 shows a schematic structural diagram of the water-passing bracket 100 provided in this embodiment. Figure 6 As shown, there are at least two salt absorption ports 102 , which are spaced apart along the circumference of the water-passing bracket 100 to improve the salt absorption efficiency and thus improve the regeneration efficiency of the water softening device.

[0051] In order to reduce the residual brine in the box, in this embodiment, the position of the salt absorption mechanism in the box is recessed downward so that the brine in the box can flow to the salt absorption mechanism, ensuring that the brine in the box is fully absorbed, so that there is little or even no residual brine in the box, thereby achieving the effect of a dry salt box. At the same time, it can avoid the growth of bacteria caused by long-term storage of brine in the box, thereby fully ensuring the water safety of users.

[0052] Figure 7 FIG. 1 shows a cross-sectional view of the water-passing bracket 100 provided in this embodiment. Figure 7 and combined Figure 2 As shown, the salt absorption mechanism also includes a salt absorption tube 200, which is plugged into the water-passing bracket 100. The simple structure facilitates assembly of the salt absorption tube 200 and the water-passing bracket 100. To ensure accurate insertion of the salt absorption tube 200 and the water-passing bracket 100, a stopper step 1011 is provided on the inner wall of the water-passing channel 101, protruding toward its central axis. The bottom of the salt absorption tube 200 abuts against the stopper step 1011. When the operator assembles the salt absorption tube 200 onto the water-passing bracket 100, the contact between the bottom of the salt absorption tube 200 and the stopper step 1011 indicates that both are properly installed, enabling quick and accurate installation of the salt absorption tube 200 and the water-passing bracket 100.

[0053] Continue as Figure 2 、 Figure 3 as well as Figure 6 As shown, the salt absorption mechanism further includes a water retaining grille 400, which is sleeved onto the outside of the water passage bracket 100. A floating space is formed between the inner wall of the water retaining grille 400 and the outer wall of the water passage bracket 100, allowing the sealing float 300 to rise and fall. The water retaining grille 400 is provided with grille holes 401. By providing the water retaining grille 400 outside the water passage bracket 100, it can block salt particles, preventing larger salt particles from being adsorbed at the salt absorption port 102 and causing blockage. Optionally, a filter is provided on the grille holes 401 to further enhance the effectiveness of filtering out salt particles.

[0054] To achieve a stable connection between the water retaining grille 400 and the water overflow bracket 100, in this embodiment, a clamping member 130 is provided at the top of the water overflow bracket 100. The top of the clamping member 130 extends out of the floating space and engages with the top of the water retaining grille 400. A limiting extension 120 is provided at the bottom of the water overflow bracket 100, extending away from its central axis. The bottom of the water retaining grille 400 abuts against the limiting extension 120. The clamping member 130 can achieve an upper limit on the water retaining grille 400, preventing it from falling out from above the water overflow bracket 100. The limiting extension 120 can achieve a lower limit on the water retaining grille 400, preventing it from falling out from below the water overflow bracket 100. The clamping member 130 and the limiting extension 120 cooperate with each other to achieve a stable connection between the water retaining grille 400 and the water overflow bracket 100.

[0055] Specifically, the clamping member 130 includes a connecting portion 131 and a hook portion 132. The connecting portion 131 is connected to the top of the water-passing bracket 100. One end of the hook portion 132 is connected to the end of the connecting portion 131 facing away from the water-passing bracket 100, and the other end extends in a direction away from the axis of the water-passing channel 101. The bottom of the hook portion 132 can abut against the top of the water-blocking grille 400, and the clamping member 130 can undergo elastic deformation. When assembling the water-passing bracket 100 and the water-blocking grille 400, the water-blocking grille 400 can be inserted from above the water-passing bracket 100 while squeezing the clamping member 130. When the clamping member 130 extends from above the water-blocking grille 400, it can be clamped to the top of the water-blocking grille 400 under the action of its own elastic restoring force. At this time, the bottom of the water-blocking grille 400 abuts against the limiting extension portion 120, thereby achieving rapid assembly of the water-passing bracket 100 and the water-blocking grille 400.

[0056] Optionally, there are multiple clamping members 130 , which are arranged at intervals along the circumference of the water-passing bracket 100 to improve the stability of the connection between the water-passing bracket 100 and the water retaining grille 400 .

[0057] The following combination Figures 1 to 7 Briefly describe the assembly steps of the salt absorption mechanism:

[0058] 1) First, install the sealing floating member 300 on the water-passing bracket 100 to form an assembly;

[0059] 2) The water retaining grille 400 is placed over the assembly in step 1) from above the water-passing bracket 100. Simultaneously, the water retaining grille 400 compresses the plurality of clips 130, causing them to converge toward the center of the water-passing channel 101. When the clips 130 extend from above the water retaining grille 400, they engage the top of the water retaining grille 400 under their own elastic restoring force. At this point, the bottom of the water retaining grille 400 abuts against the limiting extension 120.

[0060] 3) Insert the salt absorption tube 200 into the water passage 101 . When the bottom of the salt absorption tube 200 abuts against the limiting step 1011 , the tube is installed in place.

[0061] It should be noted that when the salt absorption tube 200 is inserted into the water passage 101 , it can also play a role in opening the clamping member 130 on the inner side of the clamping member 130 , further ensuring the stability of the clamping member 130 and the water retaining grille 400 .

[0062] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
