Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically providing a water purification device and its sliding cover mechanism and salt tank. Background Technology

[0002] Water softeners, as essential water purification devices for household water treatment, remove calcium and magnesium ions from water through resin adsorption to reduce water hardness. However, once the resin becomes saturated, it needs to be regenerated by adding water softening salt to restore its softening function. Currently, most mainstream water softener salt tank caps on the market use an outward or upward opening structure. When the water softener salt tank is installed in a relatively enclosed and narrow space such as a cabinet, there are significant drawbacks: due to the limited operating space, users cannot apply sufficient opening torque, and if the equipment is not installed correctly or there are installation errors, the salt cap is prone to mechanical interference with the cabinet, resulting in the inability to open properly or even damage to the cap structure. Utility Model Content

[0039] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. To better illustrate the present invention, numerous specific details are provided in the following detailed description. Those skilled in the art should understand that the present invention can be implemented even without certain specific details.

[0040] In the description of this utility model, terms such as "upper," "lower," "inner," "outer," "left," "right," "front," and "rear," which indicate direction or positional relationships, are based on the actual direction or positional relationships in practical application. These terms are used merely for ease of description and do not indicate or imply that the device to be protected must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, ordinal numbers such as "first" and "second" are used only for convenience of explanation and are not used to indicate or imply relative importance.

[0041] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Please see Figures 1 to 13 This utility model provides a sliding cover mechanism for a water purification device. The sliding cover mechanism 1 includes a cover body 11 and a sliding cover 12. The sliding cover 12 is slidably connected to the cover body 11 to open or close the opening 113 formed on the cover body 11. A limiting structure is also provided between the sliding cover 12 and the cover body 11 to limit the sliding distance of the sliding cover 12.

[0043] Specifically, such as Figure 5 and Figure 6 As shown, the opening 113 extends from the top surface of the cover body 11 to the side surface of the cover body 11, and the shape of the sliding cover 12 is adapted to the shape of the opening 113, such as... Figure 2 and Figure 3 As shown, the sliding cover 12 includes a top cover 121 and a side cover 122 connected to each other. The top cover 121 and the side cover 122 are arranged perpendicularly to each other, making the entire sliding cover 12 L-shaped, so that the sliding cover 12 can be adapted to the opening 113 formed on the cover body 11. When moving the sliding cover 12, the side cover 122 can act as a force-applying component for the user, allowing the user to more easily apply force to the sliding cover 12, thereby facilitating the user to push the sliding cover 12 to slide on the cover body 11.

[0044] The limiting structure includes a slidingly engaged limiting member 13 and a limiting groove 14. In one embodiment, the limiting member 13 is disposed on the cover body 11, and the limiting groove 14 extends along the sliding direction of the sliding cover 12 and is disposed on the sliding cover 12. In another embodiment, the limiting member 13 is disposed on the sliding cover 12, and the limiting groove 14 extends along the sliding direction of the sliding cover 12 and is disposed on the cover body 11.

[0045] It should be noted that, for ease of description, the following description will be based on the example of the limiting member 13 being set on the cover body 11 and the limiting groove 14 being set on the sliding cover 12.

[0046] Please see Figure 3 and Figure 4The limiting groove 14 includes a first locking groove 141, a second locking groove 142, and a slide 143 connecting the first locking groove 141 and the second locking groove 142. The slide 143 extends along the sliding direction of the sliding cover 12. The first locking groove 141 and the second locking groove 142 are respectively located at both ends of the sliding path of the limiting member 13. During the sliding process of the sliding cover 12, when the limiting member 13 reaches the position of the first locking groove 141 or the second locking groove 142 as the sliding cover 12 moves, it will be immediately and firmly locked, thereby effectively limiting the sliding distance of the sliding cover 12 and ensuring that it will not slide out of the predetermined effective working range.

[0047] In this way, not only is the sliding range of the sliding cover 12 effectively constrained, preventing it from slipping out due to excessive sliding, but the opening and closing positions of the sliding cover 12 can also be determined according to actual needs, making the sliding range of the sliding cover 12 perfectly match the specific working scenario. Moreover, when the user manually moves the sliding cover 12, the first slot 141 and the second slot 142 can also play a unique feedback role. In other words, when the sliding cover 12 moves to the corresponding slot position, the user can clearly feel the change in resistance of the limiting member 13 being stuck, thus clearly judging whether the sliding cover 12 has moved into place, which makes it convenient for the user to perform operations such as adding salt.

[0048] Furthermore, such as Figure 3 and Figure 4 As shown, the width of the first slot 141 and the width of the second slot 142 are both greater than the width of the slide 143. The width direction of the slide 143 is perpendicular to the extension direction (i.e., the length direction) of the slide 143. The dimension of the first slot 141 measured along the width direction of the slide 143 is the width of the first slot 141, and the dimension of the second slot 142 measured along the width direction of the slide 143 is the width of the second slot 142.

[0049] The slide 143 serves as the channel for the sliding of the limiting member 13. Its relatively narrow width primarily guides the sliding direction. The first and second slots 141 and 142 are wider, providing more space for the limiting member 13 to slide deeper into the slots when it reaches the slot position. This deeper embedding increases the contact area and friction between the limiting member 13 and the slot, effectively securing the sliding cover 12 in the open or closed position and ensuring it does not slide out of its intended working range. Furthermore, when the user manually moves the sliding cover 12, the limiting member 13 moves from the narrower slide 143 into the wider first or second slot 141, creating a noticeable change in resistance. This change in resistance is clearly transmitted to the user through tactile feedback, allowing them to intuitively perceive that the sliding cover 12 has moved to the open or closed position without additional observation or confirmation, thus improving the convenience and accuracy of operation.

[0050] Furthermore, the shapes of the first slot 141 and the second slot 142 both match the shape of the limiting member 13. When the shape of the limiting member 13 (the part that mates with the slot) matches the shapes of the first slot 141 and the second slot 142, the limiting member 13 can accurately engage in the slot when the sliding cover 12 slides to the open or closed position, achieving precise positioning. This precise positioning ensures that the sliding cover 12 remains stably in the preset position each time, avoiding any impact on the normal use of the equipment due to positional deviations. For example, it prevents the sliding cover 12 from being incompletely opened, causing inconvenience in adding salt, or from being incompletely closed, affecting the sealing of the equipment.

[0051] Please see Figures 8 to 10 The limiting member 13 includes an elastic element 131 and a sliding element 132. The sliding element 132 is elastically connected to the cover body 11 via the elastic element 131, and is slidably disposed within the limiting groove 14. The sliding element 132 is a rolling element, for example, a ball bearing; the elastic element 131 is specifically a spring, with one end connected to the rolling element and the other end connected to the cover body 11. When the limiting groove 14 includes a first slot 141, a second slot 142, and a slide rail 143 connecting the first slot 141 and the second slot 142, the sliding element 132 can move between the first slot 141 and the second slot 142 via the slide rail 143. Furthermore, the shapes of the first slot 141 and the second slot 142 match the shape of the sliding element 132, allowing the sliding element 132 to be accurately embedded in the slot.

[0052] The elastic element 131 provides elastic restoring force to the sliding element 132. When the sliding element 132 moves with the cover body 11 to the position of the first slot 141 or the second slot 142, the elastic force of the elastic element 131 will drive the sliding element 132 to automatically engage in the corresponding slot, thereby achieving precise positioning of the sliding cover 12. Furthermore, the elastic buffering effect of the elastic element 131 makes the sliding element 132 slide more smoothly and steadily within the limiting groove 14, reducing any abrupt stops or jerks. Users do not need to exert excessive force when manually sliding the cover body 11, reducing operational difficulty and fatigue. In addition, when the sliding element 132 enters or leaves the slot, the change in elastic force of the elastic element 131 is transmitted to the user through the sliding element 132, providing tactile feedback without requiring additional observation or confirmation, thus improving the user experience.

[0053] Furthermore, such as Figure 9 As shown, the limiting component 13 also includes an open limiting cylinder 133. The limiting cylinder 133 is disposed on the cover body 11. The elastic element 131 is a spring. The limiting cylinder 133 is provided with a limiting post 134. The spring is sleeved on the limiting post 134. The sliding element 132 passes through the open and slides in cooperation with the limiting groove 14.

[0054] Specifically, such as Figure 9 As shown, the limiting cylinder 133 includes a cylinder body 1331 and a cylinder bottom 1332. When the limiting member 13 is set on the cover body 11 and the limiting groove 14 is set on the sliding cover 12, the cylinder body 1331 and the cover body 11 are integrally formed, and the cylinder body 1331 has an opening at the top of the cover body 11 for the sliding member 132 to extend out. The cylinder body 1331 and the cylinder bottom 1332 are detachably connected by snap-fit ​​or other means. The elastic member 131 is set in the space enclosed by the cylinder body 1331 and the cylinder bottom 1332. The limiting post 134 is set on the cylinder bottom 1332, and the spring is sleeved on the limiting post 134. The sliding member 132 is specifically a ball. Under the elastic action of the spring, part of the ball passes through the opening and slides with the limiting groove 14 on the sliding cover 12.

[0055] The limiting sleeve 133 constrains and guides the spring and the sliding member 132, ensuring that the extension and contraction direction of the spring and the sliding direction of the sliding member 132 are consistent. This prevents the spring from shifting or twisting during extension and contraction, further improving the stability of the limiting mechanism. Furthermore, the spring, sleeved on the limiting post 134, provides a stable and uniform elastic restoring force to the sliding member 132. When the sliding member 132 slides within the limiting groove 14 to the first or second slot 141, the spring's elastic force precisely pushes the sliding member 132 into the corresponding slot and maintains a stable position, preventing the sliding cover 12 from moving unexpectedly due to vibration, external forces, or other factors. This ensures that the sliding cover 12 remains in the accurate working position during equipment use. In addition, the limiting sleeve 133 provides a relatively enclosed and stable installation space for the spring, protecting it from interference and damage from external dust, debris, etc., thus extending the spring's service life.

[0056] In this embodiment, please refer to Figure 2 and Figure 5 A guide structure is also provided between the sliding cover 12 and the cover body 11. The guide structure includes a slidingly engaged guide member 15 and a guide channel 16, with the guide channel 16 extending along the sliding direction of the sliding cover 12. In one embodiment, the guide member 15 is disposed on the sliding cover 12, and the guide channel 16 extends along the sliding direction of the sliding cover 12 and is disposed on the cover body 11. In another embodiment, the guide member 15 is disposed on the cover body 11, and the guide channel 16 extends along the sliding direction of the sliding cover 12 and is disposed on the sliding cover 12.

[0057] In addition to the limiting structure between the sliding cover 12 and the cover body 11, a guide structure is also provided between the sliding cover 12 and the cover body 11. This guide structure can guide the sliding cover 12 to slide smoothly in a preset direction, limit the excessive degrees of freedom of the sliding cover 12, and help prevent the sliding cover 12 from deviating or getting stuck when sliding. At the same time, when the sliding cover 12 slides, the guide structure can also provide continuous and stable support for the sliding cover 12. Moreover, the guide member 15 slides in the guide channel 16, which can disperse the various forces generated during the movement of the sliding cover 12, and prevent the sliding cover 12 from shaking or vibrating due to uneven force, thereby enhancing the stability of the sliding cover 12 on the cover body 11.

[0058] Furthermore, such as Figure 5 and Figure 6 As shown, the cover body 11 includes a first cover 111 and a second cover 112 that are detachably connected; a guide channel 16 is formed on both the first cover 111 and the second cover 112. Specifically, as... Figures 11 to 13 As shown, the first cover 111 is provided with multiple snap-fit ​​grooves 1111, and the second cover 112 is provided with snap-fit ​​members 1121 that engage with the snap-fit ​​grooves 1111. The first cover 111 and the second cover 112 are detachably connected through the snap-fit ​​grooves 1111 and the snap-fit ​​members 1121. When the first cover 111 and the second cover 112 are connected, the edges of the first cover 111 and the second cover 112 together form a guide channel 16. Alternatively, the first cover 111 and the second cover 112 can also be connected by, for example, bolts or other detachable methods, which will not be described in detail in this embodiment.

[0059] When installing the sliding cover 12 and the cover body 11, the sliding cover 12 can be placed on the first cover body 111 first, and then the first cover body 111 and the second cover body 112 can be assembled and fixed by the snap-fit ​​groove 1111 and the snap-fit ​​piece 1121, so that the guide member 15 on the sliding cover 12 is installed in the guide channel 16 formed by the first cover body 111 and the second cover body 112. When disassembling, after separating the first cover body 111 and the second cover body 112, the sliding cover 12 can be removed from the cover body 11. The entire disassembly and assembly process does not require complicated operation steps, effectively improving the efficiency of installation and maintenance, and making the installation and disassembly process of the entire sliding cover mechanism 1 simpler.

[0060] Please see Figures 2 to 7When the opening 113 extends from the top surface of the cover body 11 to the side surface of the cover body 11, a limiting structure is disposed between the top surface of the cover body 11 and the sliding cover 12, and a guiding structure is disposed between the side surface of the cover body 11 and the sliding cover 12. Specifically, when the sliding cover 12 includes a top cover 121 and a side cover 122 connected to each other, the limiting structure is disposed between the top surface of the cover body 11 and the top cover 121, and the guiding structure is disposed between the side surface of the cover body 11 and the side cover 122.

[0061] By placing the limiting structure and the guiding structure on the top and side surfaces respectively, their respective functions become more independent and clearly defined. The limiting structure is primarily responsible for restricting the sliding distance of the sliding cover 12, ensuring its movement within a safe range and preventing damage to the equipment or interference with its normal use due to excessive sliding. The guiding structure focuses on guiding the sliding direction of the sliding cover 12 and providing support, ensuring the smoothness and accuracy of its movement. Together, they achieve precise control of the sliding cover 12, improving the reliability and stability of the sliding cover mechanism 1.

[0062] Furthermore, two sets of limiting structures are provided between the sliding cover 12 and the cover body 11, with each set of limiting structures located on both sides of the sliding cover 12. Similarly, two sets of guiding structures are provided between the sliding cover 12 and the cover body 11, with each set of guiding structures located on both sides of the sliding cover 12. During the sliding process of the sliding cover 12, it will be subjected to forces from different directions, such as the force exerted by the user, its own weight, and the friction generated during movement. The two sets of limiting structures and the two sets of guiding structures located on both sides of the sliding cover 12 can evenly distribute these forces to the structures on both sides, preventing excessive force on one side from causing structural deformation or damage. This makes the sliding cover 12 more evenly stressed and its movement more stable. At the same time, the balanced force can also effectively suppress the vibration of the sliding cover 12, making the sliding process smoother and more fluid, thus improving the user's operating experience.

[0063] It should be noted that the sliding cover mechanism 1 provided by this utility model can be applied not only to the salt tank of a water softener, but also to the tank 2 of other water purification equipment that needs to open or close the operating port. This embodiment will not elaborate on these applications.

[0064] Please see Figures 14 to 15 Based on the aforementioned sliding cover mechanism 1 structure, this utility model also provides a salt tank for a water purification device, which includes the sliding cover mechanism 1 of the water purification device in any of the aforementioned technical solutions.

[0065] Specifically, the salt tank also includes a tank body 2, a sliding cover mechanism 1 is disposed on the top of the tank body 2, the tank body 2 is provided with a salt filling port 21 communicating with its inner cavity, the sliding cover 12 moves along the limiting groove 14 on the cover body 11, so that the sliding member 132 is located in the first slot 141 or the second slot 142, so as to open or close the salt filling port 21. That is, when the sliding member 132 is located in the first slot 141, the salt filling port 21 is in the open state, and when the sliding member 132 is located in the second slot 142, the salt filling port 21 is in the closed state. During the movement of the sliding cover 12 on the cover body 11, when the sliding member 132 slides into the second slot 142, it indicates that the salt filling port 21 (or the sliding cover 12) is in the closed state. At this time, the opening 113 is completely sealed, which can effectively prevent dust, debris and other objects from entering the salt tank and ensure the normal operation of the water softener. When the sliding member 132 slides into the first slot 141, it indicates that the salt filling port 21 (or the sliding cover 12) is in the open state, and the user can conveniently perform operations such as adding salt.

[0066] In addition, the salt tank also includes components such as a resin tank, a brine valve, a water circuit assembly 5, a control valve 3, and a valve head cover 4. The resin tank removes calcium and magnesium ions from the water through ion exchange and other methods to reduce the water hardness. The brine valve allows brine to enter the resin tank for brine absorption and regeneration, ensuring that the equipment continuously provides qualified soft water.

[0067] Based on the aforementioned salt tank, this utility model also provides a water purification device, which includes the salt tank in any of the aforementioned technical solutions, wherein the water purification device is a water softener or other water purification device that adopts the sliding cover mechanism provided in this embodiment.

[0068] The sliding cover mechanism 1 provided by this utility model features a sliding connection between the sliding cover 12 and the cover body 11. During use, the user only needs to gently push the sliding cover 12 to smoothly open or close the opening 113. This design eliminates the constraints of installation space and torque limitations, improving user convenience and making the salt-adding process easier and more efficient. Simultaneously, a limiting structure is provided between the sliding cover 12 and the cover body 11 to restrict the sliding distance of the sliding cover 12. This ensures that the sliding cover 12 has a clearly defined position during sliding, preventing it from detaching from the cover body 11 due to excessive sliding. This guarantees the stability and reliability of the sliding cover mechanism 1. As a result, users do not need to worry about the sliding cover 12 slipping or shifting during use, allowing for more confident salt-adding operations and enhancing the user experience.

[0069] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
