Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, and in particular to a water circuit board, water circuit device and water purifier. Background Technology

[0002] In the development of modern water purifiers, the water circuit board is a key component, and its design and manufacturing directly affect the performance and production efficiency of the water purifier. Currently, most water purifiers use water circuit boards with complex internal water channels. While this structure enables various water flow treatment functions, it faces significant challenges in manufacturing and processing. Because the internal channels require precision machining, traditional mold processing techniques are insufficient to meet the requirements of efficient and stable production.

[0003] Specifically, traditional water distribution boards have irregular channels and connecting cavities, and typically employ a unidirectional mold extraction technique. This leads to complex mold design and cumbersome assembly processes, increasing production costs and time. Furthermore, the guidance and flow of water are also affected, potentially resulting in uneven water distribution and reduced water purification efficiency, thus proving insufficient in practical applications.

[0004] Therefore, it is necessary to address the aforementioned issues in order to change the current situation. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] In the development of modern water purifiers, the water circuit board is a key component, and its design and manufacturing directly affect the performance and production efficiency of the water purifier. Currently, most water purifiers use water circuit boards with complex internal water channels. While this structure enables various water flow treatment functions, it faces significant challenges in manufacturing and processing. Because the internal channels require precision machining, traditional mold processing techniques are insufficient to meet the requirements of efficient and stable production.

[0044] Specifically, traditional water distribution boards have irregular channels and connecting cavities, and typically employ a unidirectional mold extraction technique. This leads to complex mold design and cumbersome assembly processes, increasing production costs and time. Furthermore, the guidance and flow of water are also affected, potentially resulting in uneven water distribution and reduced water purification efficiency, thus proving insufficient in practical applications.

[0045] Based on this, see Figures 1 to 10 As shown, this embodiment of the utility model provides a water channel plate 110, which includes a first connecting cavity 111a, a second connecting cavity 111b, and a third connecting cavity 111c formed inside the water channel plate 110; the first connecting cavity 111a is disposed inside the water channel plate 110, and one end of the first connecting cavity 111a is located on the outer surface of the water channel plate 110, and the first connecting cavity 111a extends along a first direction; the second connecting cavity 111b is disposed inside the water channel plate 110, and the second connecting cavity 111b communicates with the first connecting cavity 111a. The opening of the second connecting cavity 111b is located on the outer surface of the water channel plate 110, and the second connecting cavity 111b extends along the second direction; the third connecting cavity 111c is located inside the water channel plate 110, and the third connecting cavity 111c is connected to the first connecting cavity 111a and the second connecting cavity 111b to form a water channel 111, the opening of the third connecting cavity 111c is located on the outer surface of the water channel plate 110, and the third connecting cavity 111c extends along the third direction; wherein, the third direction is set at an angle with the first direction and the second direction respectively.

[0046] The water channel plate 110 of this utility model forms a multi-directional water flow channel 111 layout by setting a first connecting cavity 111a, a second connecting cavity 111b, and a third connecting cavity 111c, thereby reducing the difficulty of mold processing. In the manufacturing of traditional water channel plates 110, the complex structure and single mold extraction direction lead to low production efficiency and high processing difficulty. In contrast, the structural design of this utility model effectively simplifies the mold processing process. By realizing that multiple connecting cavities extend in different directions, the mold can be flexibly extracted, reducing the complexity of mold design and assembly difficulties.

[0047] By setting the opening of the third connecting cavity 111c at an angle to the direction of the first and second connecting cavities 111b, multi-directional water flow can be promoted, fully optimizing the distribution and flow effect of the water flow. This design not only improves the water processing capacity of the water purifier 10, but also effectively avoids the problem of uneven water flow distribution, improving the water purification effect and flow stability.

[0048] Specifically, the first direction is perpendicular to the third direction, the second direction is perpendicular to the third direction, and the openings of the first connecting cavity 111a and the second connecting cavity 111b are located on opposite sides of the water channel plate 110.

[0049] In this way, the first connecting cavity 111a and the second connecting cavity 111b are connected, allowing water to flow smoothly through the water channel plate 110. This design ensures smooth fluid flow, reduces system operating resistance, and thus improves the overall water transport efficiency.

[0050] Furthermore, the third connecting cavity 111c is arranged along the length of the water channel plate 110, giving the water channel plate 110 a smaller thickness. This technical feature not only saves materials and reduces production costs, but also reduces the overall size of the equipment, improving system compactness and thus providing greater design flexibility. Specifically, when the thickness of the water channel plate 110 is controlled within an optimized range (e.g., 5mm to 10mm), the uniformity of fluid flow can be further improved.

[0051] In this embodiment, the first connecting cavity 111a has a first connecting port 1111 for connecting a water inlet pipe, while the second connecting cavity 111b has a second connecting port 1112 for connecting to an external filter element. Furthermore, the first connecting cavity 111a, the second connecting cavity 111b, and the third connecting cavity 111c are all configured in multiple groups to meet different connection requirements.

[0052] With the above design, when assembling the water circuit board 110, the user can easily connect the inlet pipe from one side of the water circuit board 110 to the first connection port 1111, and at the same time connect the external filter element from the other side of the water circuit board 110 to the second connection port 1112. This arrangement greatly facilitates the user's disassembly and assembly of the water circuit board 110, and improves the flexibility and convenience of use.

[0053] In some embodiments, the water channel plate 110 can be internally configured with multiple sets of water channels 111 according to specific needs. Each set of water channels 111 is a three-way structure formed by the combination of a first connecting cavity 111a, a second connecting cavity 111b, and a third connecting cavity 111c. This configuration enables the water channel plate 110 to effectively manage water flow and enhance the uniformity and efficiency of fluid flow. Furthermore, the number of water channels 111 can be one, two, or more sets, and is not limited to a single number. By providing multiple water channels 111, the flow rate of fluid within the water channel plate 110 can be increased, thereby further improving heat exchange efficiency.

[0054] During the processing of the water channel board 110, the core can be extracted and pulled along the first, second, and third directions respectively during mold processing to form a three-way water channel 111. The implementation of this process can not only improve the processing efficiency of the water channel board 110, but also reduce the processing difficulty.

[0055] The present invention also provides a water circuit device 100, which includes a water circuit plate 110 and a sealing component 120 in any of the above embodiments; the third connecting cavity 111c of the water circuit plate 110 also has a sealing port 1113, and the opening of the sealing port 1113 is located on the outer wall of the water circuit plate 110; the sealing component 120 is detachably connected to the water circuit plate 110, and the sealing component 120 is sealed in the sealing port 1113.

[0056] In the water channel device 100 of this embodiment, by setting the sealing component 120 to cooperate with the sealing opening 1113 of the water channel plate 110, the water channel plate 110 can be formed in one step during injection molding, reducing the complexity of the production process. Specifically, in the traditional water channel plate 110, a complex processing procedure is required to form the water channel 111 within the water channel plate 110. In the water channel device 100 of this embodiment, by setting the sealing opening 1113 on the outer wall of the water channel plate 110 and communicating with the water channel 111, the mold can be directly demolded along the axial direction of the sealing opening 1113 during the injection molding process. During the assembly process, the sealing component 120 seals the sealing opening 1113 to form the preset water channel 111. This makes disassembly and assembly convenient and facilitates subsequent maintenance, thereby reducing the processing difficulty of the water channel plate 110.

[0057] In this embodiment, by configuring the sealing component 120 to cooperate with the water channel plate 110, a three-way water channel 111 with at least one end penetrating through can be formed inside the water channel plate 110. Specifically, the sealing component 120 can seal one opening of the three-way water channel 111, thereby forming a preset water channel 111 structure. This design effectively reduces the manufacturing cost of the water channel plate 110 and improves processing efficiency.

[0058] In one embodiment, the sealing assembly 120 includes a sealing member 121 and a positioning member 122. The sealing member 121 is inserted into and seals the sealing opening 1113, and the positioning member 122 is detachably connected to the water circuit board 110 and is used to fix the sealing member 121 within the sealing opening 1113. This configuration allows for convenient installation and removal of the sealing assembly 120, improving the maintenance efficiency of the water circuit device 100.

[0059] Specifically, the sealing component 121 can be made of rubber or other highly elastic materials to ensure a good seal at the sealing opening 1113, thereby preventing water leakage; the sealing component 121 can also be made of rigid plastic to ensure its strength. The positioning component 122 can be designed with a threaded structure or a snap-fit ​​connection to ensure secure installation while facilitating disassembly and replacement by the user when needed. This design not only improves the sealing performance and stability of the water system device 100 but also simplifies maintenance procedures and reduces the difficulty of operation for users. Furthermore, the rationalization of the sealing component 120's structure optimizes the manufacturing process, further improving the overall performance and service life of the water system board 110.

[0060] Furthermore, the sealing component 121 has a positioning groove 1211 to facilitate connection with the positioning component 122. Specifically, the positioning component 122 is detachably connected to the water circuit board 110 and is designed to be at least partially accommodated within the positioning groove 1211, thereby securingly engaging with the sealing component 121 through a snap-fit ​​mechanism. This design significantly enhances the stability of the sealing component 121 on the water circuit board 110, effectively preventing the sealing component 121 from loosening or falling off during use, and ensuring the sealing performance and functional stability of the entire water circuit device 100.

[0061] In this embodiment, the cooperation between the positioning groove 1211 and the positioning element 122 simplifies the assembly process and improves the accuracy and reliability of the sealing assembly 120. Furthermore, this design facilitates subsequent disassembly and maintenance; users can easily remove the positioning element 122 to release the sealing element 121, making it easier to replace the sealing element 121 and reducing maintenance complexity and time costs. The effective cooperation of the sealing assembly 120 enhances the overall durability and safety of the product, while also providing higher repeatability and yield rates for mass production, thus improving production efficiency.

[0062] In one embodiment, the water circuit board 110 has a positioning hole 112, which is connected to the sealing opening 1113. When the sealing member 121 is accommodated in the sealing opening 1113, the positioning groove 1211 and the positioning hole 112 are in communication. At this time, the positioning member 122 can be inserted into the positioning hole 112 to achieve a snap-fit ​​engagement with the positioning groove 1211 and the positioning hole 112.

[0063] When assembling the sealing assembly 120 of this embodiment, the sealing member 121 is first installed in the sealing opening 1113 until the positioning groove 1211 and the positioning hole 112 are correspondingly connected. Then, the positioning member 122 is inserted through the positioning hole 112 and engaged with the positioning groove 1211, thereby fixing the sealing member 121 in the sealing opening 1113. In this embodiment, the interconnection between the positioning hole 112 and the sealing opening 1113 makes the overall structure of the water circuit board 110 compact. In a preferred embodiment, the positioning hole 112 can open from the side of the water circuit board 110. When the positioning member 122 is connected to the water circuit board 110, the positioning member 122 can be at least partially accommodated in the positioning hole 112, so that the combined structure of the water circuit board 110 and the positioning member 122 is more compact. At the same time, the water circuit board 110 can also protect the positioning member 122.

[0064] In specific embodiments, the positioning component 122 can be selected from various fastener types, such as screws, pins, or spring clips, to adapt to different installation requirements. This versatility not only improves the flexibility of the sealing component 120, but also allows for optimization for different working environments and usage conditions, ensuring the stability and sealing performance of the sealing component 121 on the water circuit board 110.

[0065] Based on this design, the snap-fit ​​engagement between the positioning element 122, the positioning groove 1211, and the positioning hole 112 ensures that the entire structure remains robust under internal and external pressure, enhancing the durability of the water system 100. Furthermore, the simplified installation process makes maintenance and replacement efficient and convenient, reducing the skill requirements for operators and meeting the convenience and efficiency demands of modern mechanical manufacturing.

[0066] Specifically, the water channel plate 110 is provided with a positioning flange 113 to enhance the support and stability of the positioning member 122. In this design, the positioning hole 112 is provided on one side of the positioning flange 113, so that when the positioning member 122 is connected to the water channel plate 110, it can at least partially abut against the positioning flange 113, thereby achieving a more secure connection and positioning the installation of the positioning member 122.

[0067] The contact between the positioning element 122 and the positioning flange 113 not only enhances the mechanical strength of the entire device but also reduces the risk of loosening due to vibration or thermal expansion and contraction. The reinforced support design also helps reduce the frequency of maintenance during long-term use, improving the service life and reliability of the water system 100. Furthermore, precise positioning improves the convenience of the assembly process, shortens assembly time, and reduces the manpower requirements for manufacturing and maintenance, meeting the current demands for efficiency and reliability in the machinery industry.

[0068] Specifically, the positioning member 122 includes an extension 1221 and a positioning part 1222 connected together. The extension 1221 is connected to the positioning part 1222, and the extension 1221 at least partially abuts against the positioning flange 113. This design ensures that the positioning member 122 receives additional support during installation, thereby improving the stability and load-bearing capacity of the overall structure. The positioning part 1222 is at least partially inserted into the positioning hole 112 and engages with the positioning groove 1211, ensuring the correct positioning and fixation of the positioning member 122 on the water channel plate 110.

[0069] In this embodiment, the shape and material selection of the extension 1221 are particularly important. It is typically made of robust metal, high-strength plastic, or highly elastic material to enhance its load-bearing capacity and positioning stability. Furthermore, the extension 1221 can be designed with different cross-sectional shapes, such as square, circular, or irregular cross-sections, to adapt to different application requirements and provide better fastening effects. The size and shape design of the positioning part 1222 should be matched according to the actual size of the positioning groove 1211 to ensure a tight snap-fit.

[0070] Specifically, the abutment design between the extension 1221 and the positioning flange 113 can effectively disperse the force applied to the positioning member 122, reducing deformation or damage caused by excessive force. At the same time, the through-hole design of the positioning part 1222 and its snap-fit ​​engagement with the positioning groove 1211 can ensure the stability of the entire structure during long-term use, greatly improving the durability of the system.

[0071] In one embodiment, the configuration of the positioning element 122 is optimized to improve the reliability and tensile strength of the connection. Specifically, the number of positioning portions 1222 is set to two, located on opposite sides of the extension portion 1221; correspondingly, the number of positioning holes 112 is also set to two, and these two positioning holes 112 are symmetrically arranged on opposite sides of the positioning flange 113. The advantage of this design is that, by combining the evenly distributed positioning portions 1222 and positioning holes 112, the force applied to the water channel plate 110 and the sealing element 121 can be effectively dispersed, thereby avoiding local stress concentration, while improving the positioning stability of the positioning element 122 and enhancing the connection stability of the sealing assembly 120.

[0072] During assembly, a quick snap-fit ​​can be achieved by simultaneously inserting two positioning parts 1222. This dual positioning design also facilitates disassembly and maintenance, reduces operational complexity, saves maintenance time and costs, and enhances product maintainability. Simultaneously, the snap-fit ​​engagement of the two positioning parts 1222 with the positioning holes 112 helps improve the tightness of the connection, reduces the risk of loosening due to vibration or thermal expansion and contraction during long-term use, and further extends the service life of the equipment.

[0073] In one embodiment, the positioning element 122 can be a spring retainer. This configuration allows the positioning element 122 to effectively achieve tight fit and positioning between components, and also provides good reset capability. Due to its elastic properties, the spring retainer is easy to install and remove during installation, offering a simpler and faster process compared to traditional positioning methods such as screws or welding. Furthermore, the spring retainer has high fatigue resistance during use, capable of withstanding multiple deformations without affecting its performance, thus ensuring that the sealing component 120 maintains a stable positioning effect during long-term use.

[0074] Another specific implementation is that the positioning element 122 can also be a plastic injection-molded pin or a stainless steel retaining pin. These alternatives not only ensure the reliability of positioning but also provide better corrosion resistance and strength according to different application environments and requirements. By using positioning elements 122 made of different materials, designers can optimize for specific environments. For example, in humid or highly corrosive environments, selecting corrosion-resistant stainless steel retaining pins can effectively extend the service life of the terminal equipment.

[0075] In summary, by selecting the appropriate positioning component 122, not only is the assembly accuracy and stability between components improved, but the ease of maintenance and durability of the whole machine are also optimized, thereby enhancing the competitiveness and adaptability of the entire equipment in the market.

[0076] Furthermore, the water circuit plate 110 is also provided with an anti-rotation protrusion 1114, which is located inside the water flow channel 111 and protrudes from the inner wall of the water flow channel 111 toward the interior of the water flow channel 111. The anti-rotation protrusion 1114 extends along the axial direction of the water flow channel 111. The water circuit device 100 also includes a one-way valve assembly 130, which includes an anti-rotation frame 131 and a one-way valve body 132. The one-way valve body 132 is detachably connected to the anti-rotation frame 131, which is inserted into the water flow channel 111. An anti-rotation groove 1311 is provided on the outer wall of the anti-rotation frame 131, and the anti-rotation protrusion 1114 engages with the anti-rotation groove 1311.

[0077] In the water circuit device 100 of this embodiment, by providing an anti-rotation bracket 131 in the one-way valve assembly 130 to cooperate with the one-way valve body 132, the anti-rotation bracket 131 can prevent relative rotation between the one-way valve assembly 130 and the water circuit plate 110 when connected to the water circuit plate 110, thereby improving the sealing performance of the water circuit device 100.

[0078] Specifically, the snap-fit ​​design of the anti-rotation protrusion 1114 and anti-rotation groove 1311 in the water circuit device 100 effectively enhances the fixing stability between the one-way valve assembly 130 and the water circuit plate 110. The unstable installation and leakage problems caused by the structural limitations of the one-way valve in the traditional water circuit device 100 can be improved by the cooperation between the anti-rotation bracket 131 and the one-way valve body 132, thereby reducing safety hazards faced by users during use and improving the reliability of the water purifier 10.

[0079] Secondly, this design simplifies the disassembly and replacement process of the one-way valve. By detachably connecting the one-way valve body 132 to the anti-rotation bracket 131, and the anti-rotation bracket 131 engaging with the anti-rotation protrusion 1114 via the anti-rotation groove 1311, users can perform maintenance conveniently and quickly without the need for cumbersome tools or complicated operations.

[0080] Furthermore, the cooperation between the anti-rotation protrusion 1114 and the anti-rotation groove 1311 effectively prevents the one-way valve from rotating unexpectedly during operation, thereby ensuring the normal operation of the water flow and avoiding the problem of reverse water flow direction caused by rotation. This measure greatly improves the working stability of the water purifier 10 and extends its service life.

[0081] Furthermore, the anti-rotation frame 131 is further optimized in design, and the width of the anti-rotation groove 1311 arranged along the axial direction gradually increases. Specifically, the anti-rotation groove 1311 is wider on the side that contacts the first end of the anti-rotation frame 131, while it is narrower near the end of the anti-rotation frame 131.

[0082] Therefore, during the installation of the anti-rotation bracket 131 into the water flow channel 111, the large end opening of the anti-rotation groove 1311 first engages with the anti-rotation protrusion 1114. As the opening of the anti-rotation groove 1311 gradually narrows, the engagement between the anti-rotation groove 1311 and the anti-rotation protrusion 1114 allows for positioning of the anti-rotation bracket 131, improving installation accuracy and ease of use. Simultaneously, the engagement between the anti-rotation protrusion 1114 and the anti-rotation groove 1311 further enhances the engagement precision, thereby improving the installation stability of the anti-rotation bracket 131.

[0083] With this gradually widening anti-rotation groove 1311 design, a better positioning effect can be achieved when the anti-rotation bracket 131 is inserted into the water flow channel 111, reducing errors during the installation process. The advantage of this design is that the top-down insertion method allows for a more convenient operation when installing and removing the anti-rotation bracket 131, avoiding reverse installation or poor contact that may occur due to structural limitations, thus effectively reducing the risk of leakage.

[0084] Furthermore, along the axial direction of the water channel 111, the width of the anti-rotation protrusion 1114 gradually decreases, and the width of the anti-rotation protrusion 1114 is smaller at the end near the opening of the water channel 111 than at the end near the interior of the water channel 111.

[0085] With this configuration, when the anti-rotation bracket 131 is connected to the water channel 111, the anti-rotation protrusion 1114 can further enhance the guiding effect of the installation of the anti-rotation bracket 131, thereby improving the installation accuracy and convenience of the anti-rotation bracket 131.

[0086] In a specific implementation, the anti-rotation protrusion 1114 can adopt a tapered structure to position the anti-rotation groove 1311 and the anti-rotation protrusion 1114 during installation. Furthermore, the anti-rotation protrusion 1114 can be made of corrosion-resistant plastic or metal alloy to ensure its durability during long-term use, thereby extending the service life of the entire water system 100. By setting this tapered anti-rotation protrusion 1114, not only can the ease of installation of the anti-rotation bracket 131 be effectively improved, but also the installation accuracy and stability of the anti-rotation bracket 131 can be enhanced.

[0087] In one embodiment, the anti-rotation frame 131 is further provided with reinforcing ribs 1312, which are designed to enhance the structural stability and load-bearing capacity of the anti-rotation frame 131. Specifically, the reinforcing ribs 1312 are disposed on the inner wall of the anti-rotation frame 131, and their extension direction is perpendicular to the axial direction of the anti-rotation frame 131. This design allows the anti-rotation frame 131 to effectively disperse the force when subjected to water flow impact and external forces, improve the overall rigidity, and avoid deformation or damage caused by long-term use. In addition, the presence of reinforcing ribs 1312 can reduce the stress concentration caused by water flow on the anti-rotation frame 131 when water flows through it, which helps to extend the service life of the anti-rotation frame 131.

[0088] The advantage of this design lies in the fact that the added reinforcing ribs 1312 not only enhance the structural strength of the anti-rotation frame 131 but also ensure the reliability of fastener installation, avoiding assembly problems caused by insufficient structural strength. In specific implementations, the reinforcing ribs 1312 can be multiple evenly distributed ribs, or designed with different shapes and thicknesses depending on the actual application, to achieve better support and reduce manufacturing costs. Through this design, the anti-rotation frame 131 maintains a good water flow channel while possessing higher stability and safety, meeting the needs of mechanical equipment under high-load operating conditions.

[0089] In addition, the reinforcing rib 1312 can be made of high-strength plastic or metal, which not only ensures excellent corrosion resistance but also provides sufficient strength and durability while reducing the overall weight of the equipment. This material selection also greatly improves the reliability and durability of the water system 100.

[0090] Furthermore, the design of the reinforcing ribs 1312 for the anti-rotation frame 131 has been further optimized, with multiple reinforcing ribs 1312 spaced apart along the axial direction of the anti-rotation frame 131. This layout not only effectively enhances the overall structural strength of the anti-rotation frame 131 but also improves its resistance to water flow impact. In this way, the rigidity of the anti-rotation frame 131 is significantly improved, thereby avoiding deformation or damage under high-load operating conditions and ensuring the long-term reliability of the equipment.

[0091] In terms of specific implementation, the spaced reinforcing ribs 1312 can be designed in different shapes, such as strips, arcs, or other shapes that conform to fluid dynamics, to further enhance the stability and smoothness of fluid flow. This design can effectively improve the flow state of fluid within the anti-rotation frame 131, reduce eddies generated by the water flow, and thus improve the efficiency of the entire water system device 100. In addition, reasonable spacing can reduce material waste during manufacturing, while achieving optimal support effect with limited space.

[0092] In terms of material selection, the multiple reinforcing ribs 1312 can be made of high-strength composite materials or metals to reduce weight and enhance durability, ensuring that they are not easily corroded or aged under various environmental conditions. The use of this material not only improves the equipment's compressive strength but also helps maintain excellent working performance during long-term use.

[0093] In summary, the multiple spaced reinforcing ribs 1312 fully utilize their structural strengthening function in the design of the anti-rotation frame 131, providing strong support for the stability and service life of the overall water system device 100.

[0094] The present invention also provides a water purifier 10, which includes a water circuit device 100 and a filter element assembly 200 in any of the above embodiments; the filter element assembly 200 is connected to the water circuit plate 110 of the water circuit device 100, and the filter element assembly 200 is connected to the second connecting cavity 111b.

[0095] It is understood that in the water purifier 10 of this embodiment, by providing a water circuit device 100 having a water circuit board 110 as described in any of the above embodiments, the water circuit board 110 forms a multi-directional water flow channel 111 layout by providing a first connecting cavity 111a, a second connecting cavity 111b, and a third connecting cavity 111c, thereby reducing the difficulty of mold processing. In the traditional manufacturing of water circuit boards 110, the complex structure and single mold extraction direction lead to low production efficiency and high processing difficulty. In contrast, the structural design of this utility model effectively simplifies the mold processing process. By realizing that multiple connecting cavities extend in different directions, the mold can be flexibly extracted, reducing the complexity of mold design and assembly difficulties, thereby reducing the manufacturing cost of the water purifier 10 and improving processing efficiency.

[0096] By setting the opening of the third connecting cavity 111c at an angle to the direction of the first and second connecting cavities 111b, multi-directional water flow can be promoted, fully optimizing the distribution and flow effect of the water flow. This design not only improves the water processing capacity of the water purifier 10, but also effectively avoids the problem of uneven water flow distribution, improving the water purification effect and flow stability.

[0097] Of course, in some embodiments, the water purifier 10 also includes a housing structure 300, within which the water circuit device 100 and filter element assembly 200 are housed. The housing structure 300 effectively protects the internal components, preventing external environmental factors from affecting the water circuit device 100 and filter element assembly 200. Simultaneously, the design of the housing structure 300 provides the device with a good appearance and ergonomic support, making the water purifier 10 more comfortable and convenient to use. For the housing material, corrosion-resistant plastics or metals can be used, which improves strength while ensuring overall aesthetics.

[0098] Furthermore, suitable ventilation holes or heat dissipation vents are designed on the exterior of the housing structure 300 to ensure good heat dissipation performance of the water purifier 10 during operation, thereby improving the stability and efficiency of the equipment. In some embodiments, the housing structure 300 may also be designed with a replacement indicator function, allowing users to easily understand the status of the filter element through indicator lights or a display screen and replace it in a timely manner to ensure the normal operation of the water purifier 10.
