Description

Technical Field

[0001] This application relates to the field of water purifier technology, and in particular to a water purifier / drinking machine. Background Technology

[0002] In current water purifier products, the structure typically includes both a water softening section and a water purification section. These two key components play an indispensable role in ensuring the water purifier achieves high-quality and efficient water treatment. However, it is undeniable that the connection between the water softening and purification sections in existing water purifiers is not secure, leading to frequent loosening and displacement during operation. These instabilities not only affect the normal flow of water between the two sections, reducing purification efficiency, but also potentially cause leaks. Leaks can damage the internal structure of the water purifier itself, shortening its lifespan, and negatively impact the surrounding home environment, causing issues such as wet floors and damp furniture, significantly reducing the user experience and product reliability.

[0050] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0052] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0053] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0055] This application discloses a water purifier 001; please refer to [link / reference]. Figure 1 The system includes a water softening system 002, a water purification system 003, and a hot water system 004. The water softening system 002 includes a resin tank 010, which typically contains ion exchange resin. This resin is a material with ion exchange capabilities, capable of exchanging ions with those in the water. When tap water is supplied to the water purifier 001 from an external source, it first flows through the resin tank 010. The water purifier 001 then uses the ion exchange softening principle to soften the tap water. The resin tank 010 includes multiple outer cylinders 012 for filling with the ion exchange resin. These multiple outer cylinders 012 are connected sequentially, which not only achieves continuous softening but also enhances the softening effect.

[0056] For example, the outer cylinder 012 is preferably configured as two cylinders, each filled with resin. While one cylinder is softening tap water, the other can regenerate the resin. This ensures an uninterrupted supply of softened water, greatly improving the efficiency of the softening process and continuously providing softened water to users. This meets the continuous water needs of different scenarios, such as households or industries, and ensures the stability and reliability of the entire water purifier 001. Simultaneously, it allows for a relatively balanced resin load in each outer cylinder 012, preventing resin fatigue and accelerated aging caused by overuse in a single cylinder, thus extending the resin's lifespan and ensuring the durability of the softening effect. Furthermore, the resin in different outer cylinders 012 can be configured differently according to requirements. For example, the resin in one outer cylinder 012 can perform initial softening, removing most of the calcium and magnesium ions, while the resin in the other outer cylinder 012 performs deep softening, further reducing the content of hardness ions in the water. This achieves the purpose of graded softening, improving the softening effect and ensuring that the softened water quality is more stable and meets usage requirements.

[0057] In this embodiment, please refer to Figure 1 The water purification system 003 includes a middle shell 12, which is disposed opposite to the resin tank 010. Specifically, multiple outer cylinders 012 are located on the same side of the middle shell 12, and the multiple outer cylinders 012 are arranged along the length direction L of the middle shell 12, that is, the arrangement direction of the multiple outer cylinders 012 is consistent with the length direction L of the middle shell 12. The water purification system 003 also includes a primary filter element 501 and a secondary filter element 502 installed in the middle shell 12. The axis of the primary filter element 501 is parallel to that of the secondary filter element 502, and the secondary filter element 502 is connected to the primary filter element 501. The primary filter element 501 is preferably a pre- and post-filter element, and the secondary filter element 502 is preferably a reverse osmosis filter element. The soft water treated by the water purification system 002 can flow through the primary filter element 501 and the secondary filter element 502 in sequence for filtration. This provides a more comprehensive and refined filtration and purification of the soft water treated by the water purification system 002, thereby significantly improving the quality of the pure water generated after purification by the water purification system 003, and providing users with safer, healthier, and higher quality pure water.

[0058] Understandably, please see Figure 1The length direction L of the aforementioned middle shell 12 is also the direction consistent with the axial direction of the primary filter element 501. The cut-off surface of the middle shell 12 perpendicular to the axis of the primary filter element 501 and having a port for assembling the primary filter element 501 is defined as the front side; the end face of the middle shell 12 perpendicular to the axis of the primary filter element 501 and opposite to the front side is defined as the back side; and the side of the middle shell 12 along the axial direction of the primary filter element 501 and adjacent to the front side is defined as the side side. The resin tank 010 is preferably located near the side side of the middle shell 12, so that the middle shell 12 and the resin tank 010 are arranged side-by-side. Furthermore, the soft water system 002 and the water purification system 003 are both located on the same side of the hot water system 004, and the hot water system 004 is preferably located near the back side of the middle shell 12. The hot water system 004 is connected to the water purification system 003, thus the hot water system 004 can heat the purified water filtered by the water purification system 003.

[0059] This arrangement results in a more compact layout between the middle shell 12 and the resin tank 010, allowing for more efficient use of limited space. This helps save space in the overall water purifier 001, making it suitable for installations in smaller spaces, such as home kitchens and small offices. Meanwhile, the hot water system 004 is located near the back of the middle shell 12 and connected to the water purification system 003. This arrangement ensures that the purified water filtered by the water purification system 003 enters the hot water system 004 for heating via a more efficient path, reducing bends and resistance in the pipes. This improves the smoothness of water flow and the system's operating efficiency, reducing pressure loss and energy consumption that could result from poor water flow.

[0060] It should be further noted that the two adjacent outer cylinders 012 are connected. This connection can be either welded, integrally molded, or bolted, making the overall structure of the resin tank 010 more robust and reliable.

[0061] Because the connection between the middle shell 12 and the resin tank 010 is not secure, instability such as loosening and displacement often occurs during actual operation. These instabilities not only affect the normal transmission of water between the two parts, reducing water purification efficiency, but may also cause leakage. Once a leak occurs, it will not only damage the internal structure of the water purifier 001 itself, shortening its service life, but may also have an adverse impact on the surrounding home environment.

[0062] Based on this, the inventor provides a preferred embodiment, which can be found in conjunction with the following: Figure 1 , Figure 2 and Figure 3As shown, the resin tank 010 is provided with a first insertion part 017, which is located on the wall of the outer cylinder 012. The middle shell 12 is provided with a second insertion part 52, which is located on the side of the middle shell 12. The first insertion part 017 and the second insertion part 52 are inserted into each other. This arrangement will have the following technical effects:

[0063] On the one hand, it can effectively resist external forces such as vibration and impact generated during the transportation or operation of the water purifier 001, greatly improving the stability of the connection between the middle shell 12 and the resin tank 010, reducing the possibility of loosening and displacement between the middle shell 12 and the resin tank 010, and ensuring that the entire water purifier 001 remains stable during operation. At the same time, the pressure, tension and other forces borne by the water purifier 001 during operation can also be evenly distributed to the middle shell 12 and the resin tank 010 through the insertion and engagement between the first insertion part 017 and the second insertion part 52, avoiding excessive local stress on the middle shell 12 and the resin tank 010, further enhancing the connection reliability of the water purifier 001, thereby extending the service life of the water purifier 001.

[0064] On the other hand, the first insertion part 017 and the second insertion part 52 are inserted and cooperated, which enables the middle shell 12 and the resin tank 010 to quickly and accurately determine their relative positions during installation. As long as the insertion is carried out in accordance with the design requirements, the installation positions of the middle shell 12 and the resin tank 010 can be accurately positioned, avoiding problems such as poor water flow and loose connection caused by position deviation.

[0065] Preferably, please refer to the following for details. Figure 2 and Figure 3 As shown, the first insertion part 017 extends along the axial direction of the outer cylinder 012, and the extension direction of the second insertion part 52 is perpendicular to the axial direction of the primary filter element 501. The first insertion part 017 is fixedly connected to the outer cylinder 012 or integrally formed, and the second insertion part 52 is fixedly connected to the middle shell 12 or integrally formed. The fixed connection here is preferably a welded connection.

[0066] This design not only ensures that both the first insertion part 017 and the second insertion part 52 possess high structural strength, greatly enhancing the connection strength between the inner shell 12 and the resin tank 010, but also effectively resists various external forces during equipment operation. This allows stress from different directions to be rationally distributed to the outer cylinder 012 and the inner shell 12 through the insertion parts, preventing stress concentration at a single point or area. This further improves the stability and reliability of the connection between the inner shell 12 and the resin tank 010, thereby reducing the risk of loosening or breakage. Simultaneously, the insertion fit between the first insertion part 017 and the second insertion part 52 can also restrict displacement between the inner shell 12 and the resin tank 010 along the axial direction of the outer cylinder 012 and along the length L of the inner shell 12, achieving precise and rapid positioning.

[0067] It should be noted that the first insertion part 017 may be configured as one, which may be disposed on one of the outer cylinders 012 or between two adjacent outer cylinders 012. Preferably, multiple first insertion parts 017 are configured, with at least two of the multiple outer cylinders 012 having a first insertion part 017, and / or, a first insertion part 017 being disposed between every two adjacent outer cylinders 012. It can be understood that the number of second insertion parts 52 is adapted to the number of first insertion parts 017, and the shape and size of the second insertion parts 52 are adapted to the shape and size of the first insertion parts 017.

[0068] For example, the number of outer cylinders 012 is configured as two, and each outer cylinder 012 and the two outer cylinders 012 are provided with a first insertion part 017. On the one hand, the multiple first insertion parts 017 are inserted and fixed with the corresponding second insertion parts 52, which not only greatly increases the stability of the connection between the middle shell 12 and the resin tank 010, reducing the possibility of relative displacement or loosening between the middle shell 12 and the resin tank 010, but also evenly distributes the external force to different parts of the middle shell 12 and the resin tank 010, further enhancing the stability and reliability of the water purifier 001. At the same time, the first insertion part 017 provided between the two outer cylinders 012 can also form a direct and stable connection structure between the two outer cylinders 012, enhancing the resin tank 010's ability to resist external forces and deformation, further improving the structural strength and stability of the resin tank 010 and the entire water purifier 001.

[0069] On the other hand, such as Figure 3 As shown, the number of second insertion portions 52 on the middle shell 12 will be three, which not only enhances the overall structural strength of the middle shell 12, but also allows for fixing of the middle shell 12 from multiple directions and positions. Compared to a single second insertion portion 52, it can provide a wider and more balanced support force, connecting the middle shell 12 more firmly to the outer cylinder 012. At the same time, it can also distribute various external forces on the middle shell 12 more evenly to different positions of the middle shell 12, avoiding excessive pressure on any local area of ​​the middle shell 12, thereby reducing the possibility of stress concentration and deformation of the middle shell 12 and extending the service life of the middle shell 12.

[0070] Preferably, please refer to the following for details. Figure 2The first insertion part 017 includes a first slot wall 0171. The first slot wall 0171 and the outer cylinder 012 cooperate to form a first slot. That is, if the first insertion part 017 is disposed on the outer cylinder 012, the space enclosed by the outer cylinder 012 wall of the outer cylinder 012 and the first slot wall 0171 is the first slot. If the first insertion part 017 is disposed between the two outer cylinders 012, the space enclosed by the outer cylinder 012 walls of the two outer cylinders 012 and the first slot wall 0171 is the first slot. The second insertion part 52 is inserted into the first slot to achieve the purpose of the first insertion part 017 and the second insertion part 52 being inserted into each other.

[0071] In this embodiment, please refer to Figure 2 The aforementioned first slot wall 0171 includes a first side wall 01712 and two opposing first curved walls 01711. Each first curved wall 01711 is arc-shaped. There are two first side walls 01712, which are opposite to each other and located between the two first curved walls 01711. Each first side wall 01712 extends straight from one of the first curved walls 01711 towards the other. Both ends of each first side wall 01712 are connected to the two first curved walls 01711 respectively. The connection can be welded or integrally formed with the first side wall 01712 and the first curved wall 01711. In this case, the two first side walls 01712 and the two first curved walls 01711 will enclose and form a waist-shaped slot wall 0171. This gives the first slot wall 0171 high structural stability, providing support and constraint in multiple directions, and making it less prone to deformation, loosening, or detachment. Simultaneously, when subjected to external forces, the two first side walls 01712 and the two first curved walls 01711 can evenly distribute the external forces, thereby improving the fatigue and damage resistance of the first insertion part 017 and enhancing the overall structural strength and durability of the first insertion part 017.

[0072] Further, please see Figure 2 The first insertion part 017 further includes a first reinforcing rib 0172. Preferably, multiple first reinforcing ribs 0172 are configured and are interconnected in an alternating manner. All multiple first reinforcing ribs 0172 are located inside the first slot, and both ends of each first reinforcing rib 0172 are fixedly connected to the first slot wall 0171. Specifically, both ends of the first reinforcing rib 0172 are respectively fixedly connected to two opposite first curved walls 01711, or both ends of the first reinforcing rib 0172 are respectively fixedly connected to two opposite first side walls 01712, or one end of the first reinforcing rib 0172 is fixedly connected to the first curved wall 01711, and the other end is fixedly connected to the first side wall 01712.

[0073] The first reinforcing rib 0172 significantly increases the load-bearing capacity, bending resistance, and torsional resistance of the first slot wall 0171, preventing loosening or failure due to deformation of the first slot wall 0171. This ensures the connection accuracy and stability between the first insertion part 017 and the second insertion part 52, and also allows for a more uniform stress distribution within the first slot. When external forces act on the first slot wall 0171, the reinforcing rib acts as a stress transfer bridge, transferring stress from areas of higher stress to areas of lower stress, preventing stress concentration in specific areas of the first slot wall 0171, reducing the likelihood of cracks or fatigue failure, and extending the service life of the first insertion part 017. Furthermore, the fatigue damage accumulation rate of the first slot wall 0171 slows down when subjected to repeated loads. This means that the first insertion part 017 can better resist fatigue failure during long-term use, improving its reliability and safety.

[0074] It should be noted that, along the first direction A, the extension height of the first reinforcing rib 0172 is less than the groove wall height of the first slot wall 0171. The first direction A is the opposite direction to the groove depth of the first slot, thereby leaving enough space for the insertion of the second plug part 52, ensuring that the plugging process proceeds smoothly, and enabling the two plug parts to fit tightly together and achieve a good connection function.

[0075] In this embodiment, please refer to the details. Figure 3 The second insertion part 52 includes a second slot wall 521, which cooperates with the middle shell 12 to form a second slot. The second slot wall 521 includes a second side wall 5212 and two opposing second curved walls 5211, each of which is arc-shaped. Two second side walls 5212 are arranged opposite each other and located between the two second curved walls 5211. Each second side wall 5212 extends straight from one of the second curved walls 5211 towards the other, and both ends of each second side wall 5212 are connected to the two second curved walls 5211 respectively. This connection can be either welded or integrally formed, in which case the two second side walls 5212 and the two second curved walls 5211 will enclose and form a waist-shaped slot wall 521.

[0076] Understandably, the shape of the second curved wall 5211 matches the shape of the first curved wall 01711, and the arc length of the second curved wall 5211 is smaller than that of the first curved wall 01711. Therefore, when the second insertion part 52 is inserted into the first insertion part 017, the first curved wall 01711 abuts against the second curved wall 5211, and the first side wall 01712 abuts against the second side wall 5212, achieving precise positioning and fit, and avoiding misalignment or displacement. Simultaneously, it can distribute the external force more evenly, reducing excessive local stress and enhancing the stability of the connection between the second insertion part 52 and the first insertion part 017, enabling the water purifier 001 to withstand greater external forces without easily loosening or being damaged.

[0077] For further details, please refer to [link / reference]. Figure 3 The second insertion portion 52 further includes a second reinforcing rib 522. Preferably, multiple second reinforcing ribs 522 are configured and interconnected, all located inside the second slot. The second sidewall 5212 and the second curved wall 5211 are both fixedly connected to the second reinforcing ribs 522. Specifically, both ends of the second reinforcing rib 522 are fixedly connected to two opposite second curved walls 5211, or both ends of the second reinforcing rib 522 are fixedly connected to two opposite second sidewalls 5212, or one end of the second reinforcing rib 522 is fixedly connected to the second curved wall 5211, and the other end is fixedly connected to the second sidewall 5212. It should be noted that along the second direction B, the extension height of the second reinforcing rib 522 is less than or equal to the height of the second slot wall 521, where the second direction B is opposite to the depth of the second slot.

[0078] The second reinforcing rib 522 effectively enhances the overall structural strength of the second insertion part 52, improving its ability to resist various external forces and reducing the risk of deformation, twisting, or even damage caused by external forces, ensuring its stable structural form under complex working conditions. Simultaneously, it distributes the stress acting on the second insertion part 52 more evenly, preventing excessive stress accumulation in a localized area, reducing the likelihood of fatigue cracks and fractures, and extending the service life of the second insertion part 52. Furthermore, while ensuring the structural strength and stability of the second insertion part 52, it also reduces the amount of material used, effectively reducing its weight and lowering raw material and manufacturing costs.

[0079] As a further preferred embodiment, the water purifier 001 also includes a first fastener, through which the resin tank 010 is connected to the middle shell 12. Thus, the first fastener further strengthens the connection between the resin tank 010 and the middle shell 12, ensuring their relative positions are fixed and reducing loosening or displacement caused by water flow impact, vibration, or other factors during the operation of the water purifier 001, making the entire structure of the water purifier 001 more stable and reliable.

[0080] Preferably, please refer to the following for details. Figure 2 The aforementioned first insertion part 017 also includes a connecting post 0173. The connecting post 0173 has a threaded hole 0174 inside, which is threaded to connect with the first fastener. The connecting post 0173 is disposed on the first reinforcing rib 0172. Specifically, the connecting post 0173 is located at the intersection of the two first reinforcing ribs 0172. During installation, the first fastener passes through the middle shell 12 and connects to the threaded hole 0174. When the first fastener is tightened, the connecting post 0173 distributes the force evenly to the first reinforcing rib 0172 and the entire structure of the first insertion part 017 through this strong support point, avoiding local stress concentration, thereby improving the load-bearing capacity and stability of the entire structure and ensuring a more secure and reliable connection between the resin tank 010 and the middle shell 12.

[0081] For further details, please refer to [link / reference]. Figure 3 The second insertion part 52 also includes a guide post with a guide through hole inside. The diameter of the guide through hole is larger than the outer diameter of the first fastener. When the resin tank 010 is inserted into the middle shell 12, the guide through hole aligns with and connects to the threaded hole 0174, allowing the first fastener to pass through the guide through hole and be threaded into the threaded hole 0174. This not only provides a clear guide path for the installation of the first fastener, but also eliminates the need for installers to repeatedly adjust the position of the first fastener to align with the threaded hole 0174 when connecting the resin tank 010 to the middle shell 12. Simply inserting the first fastener along the guide through hole will naturally align it with the threaded hole 0174, greatly improving the accuracy and efficiency of installation and reducing the time and effort required during the installation process.

[0082] As a further preferred embodiment, the water purifier 001 also includes a second fastener. The resin tank 010 is further provided with a first mounting portion 018, which protrudes from the outer wall of the outer cylinder 012 and is located outside the first insertion portion 017. The first mounting portion 018 has an assembly hole for threaded connection of the second fastener. The middle shell 12 is further provided with a second mounting portion 53, which protrudes from the outer side of the middle shell 12 and has a through hole. When the resin tank 010 and the middle shell 12 are inserted and fitted, the assembly hole aligns with and connects to the through hole. The second fastener passes through the through hole of the second mounting portion 53 and connects to the assembly hole of the first mounting portion 018. This makes the connection between the resin tank 010 and the middle shell 12 more secure, better resisting external forces generated by water flow impact and vibration during equipment operation, and reducing the possibility of loosening and displacement. Meanwhile, the arrangement of multiple connection points (first fastener and second fastener) can more evenly distribute the force acting on the connection between the resin tank 010 and the middle shell 12. Forces in different directions and positions can be transmitted and balanced through multiple connection points, avoiding connection failure caused by excessive local stress, extending the service life of the water purifier 001, and ensuring the long-term stable operation of the water purifier 001.
