Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] In the field of water treatment equipment technology, resin tanks, as the core component of soft water systems, are usually equipped with replaceable resin cores to convert raw water into soft water.

[0038] However, in practical applications, the resin tank used to support the resin core is prone to uneven stress distribution and insufficient stability under long-term use.

[0039] Please refer to Figures 1 to 3 In order to solve the above-mentioned technical problems, this application provides a plug 013, a resin tank 010 and a water purifier / softener 001. The plug 013 includes a plug body 0131, a mounting base 0132 and a plurality of reinforcing ribs 0134. The plug body 0131 has a first mounting surface 0131a, and the mounting base 0132 has a resin support surface 0132a for supporting the resin core, and also has a first support plane 0132b facing away from the resin support surface 0132a. The mounting base 0132 is disposed on the plug body 0131, and the mounting base 0132 and the plug body 0131 enclose each other to form an annular placement groove 0133 surrounding the first support plane 0132b. A plurality of reinforcing ribs 0134 are distributed at intervals around the first support plane 0132b and disposed in the annular placement groove 0133. The reinforcing ribs 0134 have a second support plane 0134a, and the portion of the reinforcing ribs 0134 with the second support plane 0134a protrudes from the first mounting surface 0131a, and the second support plane 0134a and the first support plane 0132b are on the same plane.

[0040] In this embodiment, the first support plane 0132b in the plug 013 and the reinforcing rib 0134 connected thereto abut against the bottom plate of the housing assembly. When the water purifier 001 is placed on the ground, the bottom plate, the first support plane 0132b, and the reinforcing rib 0134 come into contact to achieve the supporting effect on the plug 013 and the resin tank 010 connected to the plug 013.

[0041] In this application, by setting multiple reinforcing ribs 0134 distributed around the first support plane 0132b in the plug 013, and ensuring that the second support plane 0134a of the reinforcing ribs 0134 is on the same plane as the first support plane 0132b, the external force exerted on the plug 013 by the base plate is effectively dispersed, avoiding structural deformation caused by excessive local stress. Simultaneously, the design of the annular placement groove 0133 enhances the connection strength between the mounting base 0132 and the plug body 0131, improving overall rigidity, thereby significantly improving the structural stability and service life of the plug 013. The plug 013 in this application not only optimizes the stress distribution during use but also enhances the support capacity for the resin core, ensuring the long-term stable operation of the soft water system 002 and solving the problem of insufficient stability of the resin tank 010 in the prior art.

[0042] Specifically, the mounting base 0132 and multiple reinforcing ribs 0134 are all located on the plug body 0131, and the plug body 0131, the mounting base 0132, and the multiple reinforcing ribs 0134 are integrally formed, thereby further enhancing the structural strength of the plug 013 and ensuring the support performance of the plug 013.

[0043] Among them, the reinforcing ribs 0134 are distributed at intervals around the first support plane 0132b, which can effectively disperse the external force acting on the plug 013 and evenly transfer the external force to multiple reinforcing ribs 0134, avoiding excessive local stress. In addition, the design that the second support plane 0134a and the first support plane 0132b are on the same plane can also ensure that the entire plug 013 structure remains flat when under stress, thereby further reducing stress concentration and reducing the risk of deformation of the plug 013 structure due to excessive local stress when it comes into contact with the base plate.

[0044] Meanwhile, the annular groove 0133 facilitates the firm fixing of the reinforcing ribs 0134 between the plug body 0131 and the mounting base 0132, enhancing the connection strength of the overall structure. The presence of multiple reinforcing ribs 0134 not only provides a larger support area for the mounting base 0132, but also increases the overall rigidity of the plug 013, thereby improving the stability of the plug 013 in long-term use.

[0045] The resin support surface 0132a of the mounting base 0132 directly contacts and supports the resin core, while the first support plane 0132b contacts the base plate, providing a stable base for the mounting base 0132. The second support plane 0134a of the reinforcing rib 0134 further enhances the support capacity of the mounting base 0132, ensuring that the resin tank 010 can operate normally.

[0046] Please refer to Figure 3 The bottom wall 0133b of the annular groove 0133 is connected to the first support plane 0132b; a portion of the reinforcing rib 0134 is provided in the annular groove 0133 and is connected to the bottom wall 0133b and the side wall 0133a of the annular groove 0133 respectively. The bottom wall 0133b of the annular groove 0133 is connected to the first support plane 0132b, ensuring that the external force transmitted from the first support plane 0132b can be directly transmitted to the bottom wall 0133b of the annular groove 0133. The reinforcing ribs 0134 are partially located in the annular groove 0133 and are connected to the bottom wall 0133b and the side wall 0133a respectively, further dispersing the force to the side wall 0133a and multiple reinforcing ribs 0134, so as to realize the force transmission method of multiple points and multiple directions, effectively avoiding stress concentration and improving the deformation resistance of the plug 013.

[0047] Furthermore, the second support plane 0134a and the first support plane 0132b of the reinforcing rib 0134 are coplanar, thereby increasing the contact area between the plug 013 and the base plate, thus sharing the pressure of the first support plane 0132b. It also forms a stable connection structure by connecting with the bottom wall surface 0133b and the side wall surface 0133a of the annular groove 0133, thereby enhancing the synergistic effect between the plug body 0131, the mounting base 0132 and the reinforcing rib 0134, improving the overall rigidity and stability of the plug 013, and increasing the assembly reliability and durability.

[0048] Optionally, the first support plane 0132b and the second support plane 0134a are connected and are arranged radially along the annular mounting groove 0133, with the second support plane 0134a spaced apart from the first mounting surface 0131a; the portion of each reinforcing rib 0134 protruding from the first mounting surface 0131a is also connected to the first mounting surface 0131a. It is understood that when the plug 013 is subjected to external force, the force can be effectively transmitted from the first support plane 0132b through the second support plane 0134a of the reinforcing ribs 0134 to various parts of the plug 013. Simultaneously, because the second support plane 0134a is spaced apart from the first mounting surface 0131a, a layered support structure is formed, reducing the deformation problem caused by the force directly acting on the first mounting surface 0131a.

[0049] Meanwhile, the portion of each reinforcing rib 0134 protruding from the first mounting surface 0131a is also connected to the first mounting surface 0131a. It can be understood that the connection between the reinforcing rib 0134 and the first mounting surface 0131a further enhances the connection strength between the reinforcing rib 0134 and the plug body 0131. On the one hand, the reinforcing rib 0134 not only provides support through the bottom wall surface 0133b and side wall surface 0133a of the annular groove 0133, but also directly reinforces the first mounting surface 0131a through its protruding portion. On the other hand, the protruding setting of the reinforcing rib 0134 and the first mounting surface 0131a form a multi-dimensional support network, which effectively improves the overall rigidity of the plug 013 and reduces the risk of deformation caused by external forces during long-term use.

[0050] Please continue to refer to Figure 3 The reinforcing rib 0134 protruding from the first mounting surface 0131a has a first buffer surface 0134b, and the first buffer surface 0134b connects the second support plane 0134a and the first mounting surface 0131a respectively. The first buffer surface 0134b is inclined or curved. In some embodiments, the first buffer surface 0134b is inclined or curved, thereby effectively changing the force transmission path and avoiding abrupt changes or concentrations of force at the connection point. This makes the force transmission from the second support plane 0134a to the first mounting surface 0131a smoother, thereby reducing local stress concentration and improving the overall deformation resistance and stability of the plug 013.

[0051] Furthermore, the inclined or curved surface design of the first buffer surface 0134b not only optimizes stress distribution but also increases the flexibility of the structure. When the plug 013 is subjected to external impact or long-term load, the buffer surface can absorb some of the energy and disperse it to a larger area, thereby reducing the risk of damage to the plug 013 due to structural fatigue and improving the durability and service life of the plug 013.

[0052] Please refer to Figure 4, along the radial direction of the annular placement groove 0133, the width of the annular placement groove 0133 is A1, the size of the second support plane 0134a is A2, and 0 < A2 / A1 ≤ 0.9. By limiting the ratio range of the size A2 of the second support plane 0134a to the width A1 of the annular placement groove 0133 to be 0 to 0.9, the proportion of the size of the reinforcing rib 0134 in the annular placement groove 0133 can be effectively limited, ensuring that the bearing and dispersion capabilities of the reinforcing rib 0134 for force reach a better balance state. When A2 / A1 approaches 0.9, it is ensured that the reinforcing rib 0134 can have sufficient support area and play a better support effect to meet the actual application requirements. When the ratio approaches 0, the consumption of the material of the reinforcing rib 0134 can be reduced. In the embodiment of the present application, the ratio range of A2 / A1 is limited within the range of 0 to 0.9, and the reinforcing rib 0134 can form a stable support structure in the annular placement groove 0133, thereby optimizing the force distribution and avoiding the stress concentration phenomenon.

[0053] Please refer to Figure 3 , the bottom wall surface 0133b of the annular placement groove 0133 has a bottom edge connected to the groove side wall surface 0133a. Along the direction perpendicular to the first support plane 0132b, the bottom edge is located on the side of the first mounting surface 0131a away from the first support plane 0132b; the bottom wall surface 0133b of the annular placement groove 0133 is an inclined surface inclined from the first support plane 0132b to the side where the bottom edge is located; or, the bottom wall surface 0133b of the annular placement groove 0133 is a curved surface curved from the first support plane 0132b to the side where the bottom edge is located.

[0054] Optionally, the bottom wall surface 0133b of the annular placement groove 0133 is designed as an inclined surface or a curved surface inclined from the first support plane 0132b to the side where the bottom edge is located. The setting of the inclined surface or the curved surface can effectively change the force transmission path. When an external force acts on the plug 013, the force will gradually disperse along the inclined surface or the curved surface of the bottom wall surface 0133b to the groove side wall surface 0133a and the bottom edge of the annular placement groove 0133, avoiding the force directly concentrating on a certain point of the first support plane 0132b or the bottom wall surface 0133b.

[0055] At the same time, the design of the inclined surface or the curved surface of the bottom wall surface 0133b not only optimizes the force distribution, but also enhances the overall structural stability of the annular placement groove 0133. The inclined surface or the curved surface can better adapt to the change of the external load, provide a larger support area and a more uniform force transmission during the force application process, ensure that the plug 013 can maintain better stability performance during long-term use, and at the same time improve its bearing capacity.

[0056] Please refer to Figure 5The angle between the sidewall 0133a of the annular groove 0133 and the first supporting plane 0132b is α, where 60°≤α≤90°. In this embodiment, by adjusting the inclination angle of the sidewall 0133a, the distribution and transmission path of force within the annular groove 0133 are further optimized. When α=90°, the sidewall 0133a is perpendicular to the first supporting plane 0132b, providing strong lateral support. When 60°≤α<90°, the sidewall 0133a gradually inclines away from the first supporting plane 0132b. Through the combined effect of axial and radial forces, the sidewall 0133a can better distribute the external force from the first supporting plane 0132b and effectively reduce the bearing pressure on the bottom wall of the groove, ensuring that the plug 013 can effectively disperse force when under stress, while also taking into account the stability and load-bearing capacity of the structure.

[0057] In addition, please refer to Figure 6 The reinforcing ribs 0134 are flat plates extending radially along the annular groove 0133. Multiple reinforcing ribs 0134 are radially and evenly distributed around the first supporting plane 0132b, with a central angle β between adjacent reinforcing ribs 0134, where 12.8°≤β≤30°. It can be understood that the radial distribution of the reinforcing ribs 0134 along the annular groove 0133, and the even distribution around the first supporting plane 0132b, allows each reinforcing rib 0134 to effectively transmit force radially to the bottom wall 0133b and side wall 0133a of the annular groove 0133. Simultaneously, the radial layout forms a radial force transmission path, transferring pressure to the outer edge of the cover 013, avoiding stress concentration in the central area.

[0058] When the central angle β = 12.8°, the number of reinforcing ribs 0134 is at most 28, and the spacing between adjacent reinforcing ribs 0134 is reduced, which enhances the torsional stiffness of the cover 013. When the central angle β = 30°, the number of reinforcing ribs 0134 is at least 12, which ensures the lower limit of the number of reinforcing ribs 0134 and maintains the supporting performance of the reinforcing ribs 0134.

[0059] In some embodiments, please refer to Figure 4Along the radial direction of the annular mounting groove 0133, the distance between the first support plane 0132b and the first mounting surface 0131a is X1, where 30mm ≤ X1 ≤ 35mm. In this application, by reasonably setting the distance range, the distance between the first support plane 0132b and the first mounting surface 0131a is ensured to be moderate. A smaller X1 improves the efficiency of force transmission from the first support plane to the periphery of the plug 013; while a larger X1 provides greater structural strength and resistance to deformation. By controlling X1 within the range of 30mm to 35mm, both effective force transmission and structural failure caused by excessively large or small distances are ensured.

[0060] Understandably, excessive spacing may lead to insufficient connection strength between the first supporting plane 0132b and the first mounting surface 0131a, thereby reducing the load-bearing capacity of the plug 013; while insufficient spacing may limit the design space of the reinforcing rib 0134 and the annular placement groove 0133, affecting their functionality. By controlling X1 within the range of 30mm to 35mm, while ensuring structural strength, sufficient space is also provided for the arrangement of other components (such as the reinforcing rib 0134), further improving the overall performance.

[0061] Please continue to refer to Figure 4 The first supporting plane 0132b is a circle with the same center as the annular groove 0133, and the diameter of the first supporting plane 0132b is D, where 37mm ≤ D ≤ 42mm. It can be understood that the diameter D of the first supporting plane 0132b is within the range of 37mm to 42mm, covering mainstream resin core specifications (35-45mm core outer diameter). By reasonably setting the size range of the first supporting plane 0132b, it is ensured that it can evenly bear external pressure. While ensuring a moderate supporting area, it also provides reasonable layout space for other components, such as the reinforcing ribs 0134 and the annular groove 0133, further improving overall performance.

[0062] In addition, please refer to Figure 1 and Figure 2The plug 013 also includes multiple supporting ribs 0135, which support the plug body 0131. These supporting ribs connect to the plug body 0131 and protrude from the first mounting surface 0131a. Multiple reinforcing ribs 0134 are arranged around the outer periphery of the annular positioning groove 0133. By adding additional support to the outside of the plug body 0131, the overall structural strength of the plug 013 is significantly enhanced. Simultaneously, the multiple reinforcing ribs 0134, arranged around the outer periphery of the annular positioning groove 0133, further distribute pressure from the annular positioning groove 0133 to the entire plug 013, avoiding excessive local stress. Furthermore, the synergistic effect of the supporting ribs 0135 and the reinforcing ribs 0134 forms a multi-dimensional support network, significantly improving the deformation resistance of the plug 013.

[0063] The supporting rib 0135 protrudes from the first mounting surface 0131a, allowing pressure to be directly transmitted from the first mounting surface 0131a to the supporting rib 0135, thereby reducing the risk of deformation caused by concentrated stress on the first mounting surface 0131a. Furthermore, the reinforcing rib 0134, positioned around the outer periphery of the ring-shaped groove 0133, further optimizes the force transmission path, ensuring that the force is evenly distributed throughout the entire plug 013 structure. This design not only improves the load-bearing capacity of the plug 013 but also extends its service life.

[0064] Furthermore, each supporting rib 0135 has a third supporting plane 0135a, and the third supporting plane 0135a is on the same plane as the first supporting plane 0132b and the second supporting plane 0134a. When the plug 013 is under stress, the first supporting plane 0132b, the second supporting plane 0134a and the third supporting plane 0135a can work together to form a continuous and flat overall supporting surface. On the one hand, this reduces the problem of local stress concentration caused by inconsistent plane heights and significantly improves the force transmission efficiency and distribution uniformity. On the other hand, by integrating the supporting functions of the supporting ribs 0135 and the reinforcing ribs 0134 onto the same plane, a multi-layer collaborative support system is formed, which further enhances the overall structural stability of the plug 013, improves the load-bearing capacity of the plug 013, and reduces the risk of deformation caused by external forces.

[0065] In some embodiments, the plug body 0131, mounting base 0132, reinforcing rib 0134, and supporting rib 0135 are integrally arranged. This arrangement significantly enhances the overall structural strength and rigidity of the plug 013. Compared with a split structure, the integrated design reduces the connection points between different components, avoiding structural failure caused by weak connections. At the same time, the plug body 0131, mounting base 0132, reinforcing rib 0134, and supporting rib 0135 form a whole, which can better withstand external loads and improve the deformation resistance of the plug 013.

[0066] In addition, the one-piece molding can ensure the geometric accuracy between the third support plane 0135a and the first support screen and the second support plane 0134a, effectively avoiding the cumulative error caused by separate processing.

[0067] Please refer to Figure 2 The plug body 0131 also has a second mounting surface 0131b facing away from the first mounting surface 0131a, and the mounting base 0132 has a portion of the resin support surface 0132a protruding from the second mounting surface 0131b. Optionally, the second mounting surface 0131b of the mounting base 0132 is used to face the resin core to support the resin core, and increases the contact area between the mounting base 0132 and the resin core, further enhancing the overall load-bearing capacity of the plug 013, so that the external force applied to the resin core can be transmitted more evenly to the mounting base 0132, and distributed throughout the entire structure through the plug body 0131, thereby improving the load-bearing capacity of the plug 013.

[0068] Furthermore, when the plug 013 is installed on the outer cylinder 012 of the resin tank 010, the protruding mounting seat 0132 can more accurately position and fix the plug 013, reducing the performance degradation caused by assembly errors. In addition, it enhances the connection strength between the mounting seat 0132 and the outer cylinder 012, ensuring the reliability of the plug 013 in long-term use.

[0069] Secondly, please refer to Figure 7 This application also proposes a resin tank 010, including an outer cylinder 012 and the aforementioned plug 013. The specific structure of the plug 013 is as described in the above embodiments. Since the resin tank 010 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
