Description

Technical Field

[0001] The present application relates to the technical field of water purification equipment, and in particular to a water purifier. Background Art

[0002] As people pay more attention to the safety and health of drinking water, water purification equipment has gradually become an important device in household and industrial applications. Most of the existing water purifiers on the market adopt an integrated design, in which the filter element is directly connected to the waterway plate. Although it can achieve water purification to a certain extent, this design faces many technical problems in actual use.

[0003] First, the direct connection of the filter element assembly causes the waterway plate to bear greater mechanical stress when it is subjected to water pressure. Due to the limited strength of the waterway plate, this design easily causes the waterway plate to be damaged after long-term use, thereby affecting the overall performance and service life of the equipment. When the waterway plate is damaged, users often need to replace the entire device, which increases maintenance costs.

[0004] Secondly, in the existing design, the booster pump and power adapter are generally placed inside the housing of the water purifier, and the layout is relatively random. This design not only leads to a messy internal circuit structure, but may also cause safety issues in the use of the equipment. For example, there is a risk of poor contact or short circuit between the booster pump and the power adapter, which threatens the user's safety to a certain extent. In addition, the messy internal structure may also make equipment maintenance and troubleshooting difficult, reducing the user experience and the maintainability of the equipment.

Detailed implementation mode

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] As people pay more attention to the safety and health of drinking water, water purification equipment has gradually become an important device in household and industrial applications. Most of the existing water purifiers on the market adopt an integrated design, in which the filter element is directly connected to the waterway plate. Although it can achieve water purification to a certain extent, this design faces many technical problems in actual use.

[0049] First, the direct connection of the filter element assembly causes the waterway plate to bear greater mechanical stress when it is subjected to water pressure. Due to the limited strength of the waterway plate, this design easily causes the waterway plate to be damaged after long-term use, thereby affecting the overall performance and service life of the equipment. When the waterway plate is damaged, users often need to replace the entire device, which increases maintenance costs.

[0050] Secondly, in the existing design, the booster pump and power adapter are generally placed inside the housing of the water purifier, and the layout is relatively random. This design not only leads to a messy internal circuit structure, but may also cause safety issues in the use of the equipment. For example, there is a risk of poor contact or short circuit between the booster pump and the power adapter, which threatens the user's safety to a certain extent. In addition, the messy internal structure may also make equipment maintenance and troubleshooting difficult, reducing the user experience and the maintainability of the equipment.

[0051] Based on this, see Figures 1 to 17 As shown, an embodiment of the present invention provides a water purifier 10, which includes a shell structure 100, a water channel device 200, a middle frame structure 300, a boosting device 400 and a filter element assembly 500; the water channel device 200 is connected to the shell structure 100; the middle frame structure 300 is arranged in the shell structure 100 and connected to the water channel device 200, and the middle frame structure 300 is provided with a accommodating chamber and a placement chamber 321, and the accommodating chamber and the placement chamber 321 are arranged at intervals; the filter element assembly 500 is accommodated in the accommodating chamber, and the filter element assembly 500 is detachably connected to the water channel device 200; the boosting device 400 includes a boosting pump 410 and a power adapter 420, the boosting pump 410 and the power adapter 420 are connected to the middle frame structure 300, and the boosting pump 410 and the power adapter 420 are respectively arranged in the placement chamber 321.

[0052] In this embodiment, the water purification device effectively solves the mechanical stress problem caused by directly connecting the filter element assembly 500 to the water circuit board in the prior art by introducing the middle frame structure 300. The middle frame structure 300 can serve as a load-bearing component, making the connection between the filter element assembly 500 and the water circuit board more stable, reducing the mechanical stress of the water circuit board during use, thus significantly enhancing the strength and durability of the water circuit board, extending the service life of the device, and reducing the maintenance cost caused by the damage of the water circuit board.

[0053] At the same time, in the design of the middle frame structure 300 of the present invention, a receiving cavity and a placement cavity 321 are provided, enabling the filter element assembly 500, the booster pump 410, and the power adapter 420 to be arranged in an orderly manner according to their functions. While providing a good layout space, this design effectively avoids the problem of messy internal wiring, improves the safety of the device, and reduces potential safety hazards caused by poor electrical contact or short circuits. This orderly layout also improves the maintainability of the device, facilitating users' daily maintenance and troubleshooting.

[0054] In one embodiment, the housing structure 100 includes an outer shell 110, a front panel 120, and a sealing cover 130. The front panel 120 and the water circuit device 200 are respectively connected to opposite sides of the middle frame structure 300, and the middle frame structure 300, the water circuit device 200, and the front panel 120 are accommodated within the outer shell 110; the front panel 120 is provided with a placement groove 121 communicating with the receiving cavity, and the sealing cover 130 is detachably connected to the front panel 120 and accommodated within the placement groove 121. This design ensures the compactness of the internal structure, thus effectively reducing space occupancy and enhancing the aesthetics and practicality of the overall device.

[0055] In this embodiment, the front panel 120 is provided with a placement groove 121 communicating with the receiving cavity, and the sealing cover 130 is detachably connected to the front panel 120 and accommodated within the placement groove 121. This design not only makes the assembly of components more flexible and convenient but also facilitates daily maintenance and troubleshooting. Specifically, the placement groove 121 of the front panel 120 can effectively guide the installation of the filter element assembly 500 from the opening of the placement groove 121 into the receiving cavity, realizing the quick replacement of the filter element assembly 500. When replacing the filter element, the user does not need to disassemble the entire device, making the maintenance process more efficient.

[0056] It is further emphasized that in this embodiment, the outer shell 110 is not only a framework for supporting the external structure but also has the function of protecting its internal water circuit device 200, middle frame structure 300, booster device 400, and filter element assembly 500. The advantage of this design is that it effectively blocks the influence of external environmental factors on the internal components, such as water vapor, dust, etc., thereby extending the service life of the device and improving the safety and reliability of the device.

[0057] In this embodiment, when the filter element assembly 500 is installed in place, the sealing cover 130 can be covered in the placement groove 121 to effectively seal the opening of the placement groove 121. This design not only ensures the tightness of the filter element assembly 500 during use, preventing potential water leakage problems, but also reduces the risk of external contaminants entering the internal structure, thereby improving the overall performance and safety of the water purifier 10.

[0058] Since the sealing cover 130 is accommodated in the placement groove 121, the surface of the front panel 120 will remain flat, which has multiple advantages. First of all, the flat surface design enhances the aesthetics of the device, improves the user's visual experience, and meets the aesthetic needs of modern homes. Secondly, the flat structure avoids dead corners during the cleaning and maintenance process, which is conducive to preventing the accumulation of dirt and scale, and improves the actual service life of the device. Further, the flat design also reduces the risk of human collision or damage caused by protrusions or depressions, improving the durability of the device and the user's safety in use.

[0059] In addition, when implementing the design of this sealing cover 130, various materials can be considered for manufacturing, such as plastics, metals, or rubbers, etc. These materials each have different advantages. The plastic sealing cover is lightweight and easy to mold, the metal sealing cover provides higher strength and corrosion resistance, while the rubber sealing cover can provide better sealing effect and flexibility. The specific selection needs to be reasonably configured according to the actual use environment and cost budget, and there is no unique limitation here.

[0060] Furthermore, a guiding inclined surface 1211 is provided at the edge of the placement groove 121.

[0061] In this embodiment, by providing the guiding inclined surface 1211 at the edge of the placement groove 121, the installation convenience of the sealing cover 130 is effectively improved. Specifically, the provision of the guiding inclined surface 1211 enables the sealing cover 130 to be smoothly guided to the correct position when installing the sealing cover 130, thereby reducing errors and operation difficulty and improving the installation efficiency.

[0062] At the same time, since the guiding inclined surface 1211 is inclined from the edge of the placement groove 121, when the user needs to remove the sealing cover 130, the finger can be easily inserted into the contact between the guiding inclined surface 1211 and the sealing cover 130, which is convenient for disassembly and assembly. This design not only enhances the user's operation convenience, but also reduces the risk of damage caused by improper disassembly and assembly, thereby improving the durability of the device.

[0063] In this embodiment, the guiding inclined surface 1211 inclines towards the lower side of the housing structure 100. Such a design demonstrates its unique functionality in practical applications. When the filter element assembly 500 is removed, if there are water droplets, the water droplets can flow out along the guiding inclined surface 1211, thus effectively preventing the water droplets from accumulating in the accommodating cavity and / or the placement groove 121. Specifically, such a drainage design can reduce the potential corrosion risk caused by the internal humid environment, extend the service life of the device, and enhance the overall user experience.

[0064] It should be added that during implementation, the inclination angle of the guiding inclined surface 1211 can be adjusted according to specific installation convenience and drainage effects. For example, the inclination angle can be set to 30 degrees, 45 degrees, or 60 degrees, which is specifically determined according to actual design requirements and is not uniquely limited here. If the inclination angle of the guiding inclined surface 1211 is too small, it may cause the water droplets to not drain smoothly, while if the inclination angle is too large, it may affect the fixing effect and stability of the sealing cover 130. Therefore, a reasonable selection needs to be made within this range.

[0065] In one embodiment, the housing structure 100 further includes a first magnetic attraction member 140 and a second magnetic attraction member 150. The first magnetic attraction member 140 is connected to the sealing cover 130, and the second magnetic attraction member 150 is connected to the front panel 120. The sealing cover 130 and the front panel 120 are magnetically coupled through the first magnetic attraction member 140 and the second magnetic attraction member 150. Through this magnetic adsorption method, the magnetic force between the first magnetic attraction member 140 and the second magnetic attraction member 150 can effectively fix the sealing cover 130, thereby ensuring the sealing effect to protect the filter element assembly 500 in the accommodating cavity.

[0066] In a preferred embodiment, the number of both the first magnetic attraction member 140 and the second magnetic attraction member 150 is set to four, and they are correspondingly arranged at the four corners of the sealing cover 130. This configuration not only enhances the connection stability but also can, to a certain extent, disperse the force acting on the sealing cover 130, making the sealing effect more uniform. When the sealing cover 130 is subjected to an external force, the four corresponding magnetic attraction members can work together, thereby enhancing the impact resistance and durability of the entire structure.

[0067] It should be noted that when the number of the sealing covers 130 is multiple, each sealing cover 130 in the system can also be provided with four first magnetic attraction members 140, which correspond to the four second magnetic attraction members 150 on the front panel 120. This design can achieve higher tightness and safety, ensuring both continuous sealing during use and convenient disassembly and assembly during maintenance. In this case, the number and arrangement of the magnetic attraction members of each sealing cover can reduce the installation error and optimize the sealing, enhancing the overall user experience of the product.

[0068] In the specific implementation manner, the first magnetic attracting member 140 and the second magnetic attracting member 150 can be made of different materials. For example, rare earth magnets, neodymium iron boron magnets, etc. These materials have excellent magnetic attracting properties and long-term magnetic stability. Using such materials can ensure that the performance of the magnetic attracting members is not affected even in high-temperature or humid environments, further improving the overall reliability of the housing structure 100.

[0069] In one embodiment, the housing structure 100 further includes a cover plate 160. The cover plate 160 is covered on the side of the front panel 120 away from the middle frame structure 300, and the cover plate 160 covers the opening of the placement groove 121; the outer shell 110 is provided with a first handle groove 111, and the orthographic projection of the first handle groove 111 on the cover plate 160 is at least partially located inside the cover plate 160; a second handle groove 161 is provided at the edge of the cover plate 160.

[0070] In the design of this embodiment, after the sealing cover 130 is placed in the placement groove 121, the user can install the cover plate 160 on the outer side of the front panel 120, thereby effectively shielding the sealing cover 130. This setting not only keeps the outer surface of the housing structure 100 flat, but also provides effective protection for the sealing cover 130, reducing the potential damage caused by external environmental factors.

[0071] It is worth mentioning that the cover plate 160 is flush with the outer surface of the outer shell 110. By using the design of the first handle groove 111 on the edge of the outer shell 110 corresponding to the cover plate 160, when the user needs to remove the cover plate 160, the finger can be easily inserted into the first handle groove 111 to pry it open, simplifying the disassembly operation and improving the convenience of use.

[0072] In this embodiment, if the number of cover plates 160 is multiple, the second handle groove 161 can be provided between two adjacent cover plates 160 and located on any one of the cover plates 160. This setting enables the user to conveniently insert the finger into the second handle groove 161 to open the corresponding cover plate 160 when it is necessary to remove any one of the two adjacent cover plates 160, further improving the user-friendliness and operation flexibility of the product.

[0073] Specifically, the material of the cover plate 160 can be selected from a variety of materials such as engineering plastics, stainless steel or aluminum alloy, depending on the actual design requirements. When using engineering plastics, its light weight and corrosion resistance can effectively improve the performance of the device in a humid environment; while choosing a metal material can enhance the structural strength and durability of the cover plate. In addition, the thickness of the cover plate 160 can be set to 2mm, 3mm and 4mm. The choice of its thickness will directly affect the rigidity and impact resistance of the cover plate, and specifically needs to be determined according to the actual application situation to ensure that there is no warping or defects when the thickness is too thin, and excessive thickness may increase the overall weight and cost.

[0074] In one embodiment, the waterway device 200 includes a waterway assembly 210 and an electrical component 220, and the electrical component 220 is connected to the waterway assembly 210; the middle frame structure 300 includes a filter element frame 310 and a water guide plate 330. A receiving cavity is provided inside the filter element frame 310, and the filter element frame 310 is also provided with a drain hole communicating with the receiving cavity, and the opening of the drain hole is located at the bottom surface of the receiving cavity; the water guide plate 330 is provided with a water guide groove 331 communicating with the drain hole, and the bottom plate of the water guide plate 330 blocks between the drain hole and the electrical component 220 in the vertical direction.

[0075] In the water purifier 10 of this embodiment, by setting the middle frame structure 300 with the water guide plate 330 to cooperate with the waterway device 200, water leakage can be discharged when disassembling and assembling the filter element assembly 500, effectively solving the problem in the prior art that the electrical component 220 in the waterway device 200 is damaged by water droplets during filter element replacement, and the reliability of the water purifier 10 is improved.

[0076] Specifically, in the current water purifier 10 in the prior art, residual water often flows out due to filter element replacement and may drip onto the electrical component 220, thereby causing electrical short circuits or equipment failures. However, in the middle frame structure 300 of this embodiment, especially the design of the water guide plate 330, an effective physical isolation can be formed between the drain hole and the electrical component 220, thus preventing water droplets from directly contacting the electrical component 220.

[0077] In addition, the design of the water guide groove 331 provided on the water guide plate 330 enables the water flowing out during the filter element replacement process to be guided to the side of the filter element frame 310, thereby significantly reducing the occurrence of backflow water phenomenon. This not only protects the safety of the electrical component 220, but also improves the convenience of filter element replacement and avoids the influence of water on the subsequent water purification effect.

[0078] In summary, the water purifier 10 of the present invention significantly solves the problems of the electrical component 220 being affected by water droplets and backflow water existing in the prior art through the structural design of the middle frame structure 300, effectively improving the safety of the water purifier 10, with a simple structure and good use effect.

[0079] Specifically, in this embodiment, the design of the waterway assembly 210 isolates between the drain hole and the electrical component 220. This design enables the water droplets in the receiving cavity to flow smoothly through the drain hole and the water guide groove 331 if there is a liquid leakage phenomenon during the disassembly and assembly of the filter element assembly 500. The bottom plate of the water guide plate 330 is specifically set as a blocking structure, enabling the water droplets to flow along the predetermined water flow path W and finally preventing the water droplets from directly dripping on the electrical component 220. In this way, the electrical component 220 can effectively avoid adverse phenomena such as short circuits and corrosion caused by water droplets.

[0080] In contrast, the design of the traditional water purifier 10 fails to provide an effective liquid drainage structure. The water droplets generated during the disassembly and assembly of the filter element often come into direct contact with the electrical components, resulting in short circuits or corrosion. This not only affects the normal use of the water purifier 10 but also shortens its service life. The water purifier 10 in this embodiment effectively avoids the impact of liquid leakage on the electrical components 220 during filter element replacement through the cooperation of the reasonably configured water guide plate 330 and the water circuit device 200, significantly improving the reliability and service life of the water purifier 10.

[0081] It should be further supplemented that the material of the water guide plate 330 can be selected from corrosion-resistant plastics or stainless steel. Both of these materials can effectively prevent the penetration and corrosion of moisture when dealing with water droplets, and do not affect the lightweight requirements of the whole machine. When the water guide plate 330 is made of plastic material, it may have a lighter weight, but its heat resistance may be slightly weaker in some extreme environments, and the water guide plate 330 can be directly formed on the middle frame structure 300 during the injection molding process of the middle frame structure 300; while stainless steel has better high-temperature resistance and durability, making it a better choice in more demanding environments. Therefore, considering different usage environments, users can choose suitable materials for manufacturing according to actual application requirements. Through the optimization of these details, the water purifier 10 in this embodiment has a more excellent user experience and a longer service life. In one embodiment, the bottom surface of the bottom plate is arranged at an angle to the axis of the accommodation cavity. By designing an angle between the bottom surface of the bottom plate and the axis of the accommodation cavity, the water flow discharged from the drainage hole can flow to a preset position through the guidance of the bottom surface, effectively avoiding the phenomenon of water droplet splashing.

[0082] Specifically, the opening of the angle formed by the bottom surface and the axis of the accommodation cavity faces the water circuit component 210. Under the guidance of the bottom surface, the water droplets can flow along the bottom surface towards the water circuit component 210 until they contact the inner wall of the water guide plate 330. This design significantly improves the drainage effect and reduces the difficulty of cleaning and maintenance.

[0083] It should be noted that the angle of the angle R can be 5 degrees, 10 degrees, 15 degrees or 20 degrees, and there is no unique limitation here. According to actual design requirements, the selection of the angle R can fluctuate within a certain range, and it is specifically optimized according to the drainage effect and spatial layout. For example, if the angle R is too small, it may cause the water flow to be unable to be effectively guided, and instead may cause water droplet accumulation; while if the angle R is too large, it may affect the overall structural design and aesthetics. Therefore, a reasonable design of the angle R can ensure effective diversion while maintaining a good device shape and structural stability. Through this angle setting, not only the risk of water droplet splashing is reduced, but also the efficiency of water flow guidance is improved, further enhancing the use reliability and user experience of the water purifier 10.

[0084] In one embodiment, the extending direction of the water guide groove 331 is perpendicular to the axial direction of the accommodation cavity, and the water guide groove 331 is arranged through the water guide plate 330. In this embodiment, by setting the extending direction of the water guide groove 331 to be perpendicular to the axial direction of the accommodation cavity, the water droplets flowing out from the drain hole can be effectively guided. After the water droplets flow to the water guide groove 331, they can flow along both sides of the middle frame structure 300, that is, along the designed water flow path W, so as to effectively avoid the electrical component 220, prevent the water droplets from directly contacting the electrical component 220, and reduce potential risks such as short circuit and corrosion.

[0085] This design not only realizes the effective diversion of water droplets, but also makes the combined structure of the middle frame structure 300 and the waterway device 200 more compact while avoiding the electrical component 220. This compact structural design can effectively save space, improve the overall structural stability and service efficiency of the product. In addition, the through arrangement of the water guide groove 331 can also reduce the sealing problems caused by multi-piece connection during the manufacturing process, thereby improving the assembly convenience and reliability.

[0086] In one embodiment, the cross-section of the water guide groove 331 is quadrilateral, and at least two side walls of the water guide groove 331 are perpendicular to the axial direction of the accommodation cavity. By designing the cross-section of the water guide groove 331 as a quadrilateral, the connection between the water guide groove 331 and the filter element frame 310 can be effectively enhanced, thereby forming a more stable support structure. This design significantly improves the overall strength of the middle frame structure 300, ensuring better durability and reliability in practical applications. In addition, the quadrilateral structure also reduces the processing difficulty during the processing process, facilitating high-efficiency mass production.

[0087] In specific implementation, the quadrilateral cross-section of the water guide groove 331 can be further refined into variants such as rectangles, rhombuses, trapezoids, etc., which not only enriches the structural design, but also can be optimized according to the principles of fluid mechanics. For example, the rectangular design can increase the smoothness of water flow, while the rhombus structure may generate a certain vortex effect on the water flow, further strengthening the mixing and guiding functions of the water flow. It is worth mentioning that if the shape of the water guide groove 331 is designed improperly, it may lead to water flow retention or poor drainage, thereby affecting the overall performance and user experience of the device.

[0088] Through this design scheme, the quadrilateral structure of the water guide groove 331 effectively improves the stability and strength of the middle frame structure 300, while simplifying the production and processing process, providing a good foundation for further technical optimization and cost control.

[0089] Furthermore, the housing structure 100 includes a front panel 120 and a sealing ring 170. The middle frame structure 300 is detachably connected to the front panel 120, and the sealing ring 170 is arranged between the front panel 120 and the middle frame structure 300.

[0090] In this embodiment, the setting of the sealing ring 170 effectively prevents the liquid leakage phenomenon that may occur after the filter element assembly 500 is separated from the water circuit device 200. When the filter element assembly 500 is detached from the water circuit device 200, the sealing ring 170 can effectively seal the rear end of the accommodation cavity, preventing any liquid from seeping into the middle frame structure 300 and the front panel 120, thus significantly improving the overall sealing performance of the water purifier 10.

[0091] It should be noted that the sealing ring 170 can adopt various forms, such as rubber rings, rubber gaskets or silicone seals, etc. Among these specific embodiments, the rubber gasket has better elasticity and sealing performance compared with other materials, so it performs excellently in dynamic sealing. If the elasticity of the sealing ring 170 is insufficient, it may lead to a reduction in the sealing effect, resulting in problems such as water leakage and affecting the normal use of the water purifier 10. Therefore, the material and specification selection of the sealing ring 170 need to be optimized according to the actual design requirements to ensure the best sealing effect.

[0092] In addition, in terms of the design quantity of the sealing ring 170, specifically, one, two or more than two can be set, and it can be flexibly configured according to the structural needs. When multiple sealing rings 170 are used, the sealing effect can be further improved, the waterproof performance of the product can be enhanced, and it can ensure a good sealing state even after multiple disassembly and assembly operations. Through the above design scheme, the sealing performance of the water purifier 10 is effectively guaranteed, thereby improving the use safety and reliability of the water purifier 10. In one embodiment, the sealing ring 170 is provided with a sealing groove 171, and the opening of the accommodation cavity is inserted into the sealing groove 171. Through the cooperation of the sealing groove 171 and the middle frame structure 300, during the assembly process, the structure of the middle frame structure 300 at the opening of the accommodation cavity can be conveniently inserted into the sealing groove 171. This design can not only effectively position the installation of the middle frame structure 300, but also significantly improve the installation accuracy, ensuring good cooperation of all components.

[0093] Specifically, the setting of the sealing groove 171 can increase the contact area between the middle frame structure 300 and the sealing ring 170. The increase in this contact area brings significant advantages. Firstly, it improves the sealing performance of the sealing ring 170, greatly reducing the risk of liquid leakage, and thus enhancing the overall reliability of the water purifier 10. In addition, the design of the sealing groove 171 also facilitates rapid assembly and disassembly, enhancing the maintainability and use convenience of the product.

[0094] In practical applications, the shape and depth of the sealing groove 171 can be customized according to different product requirements. For example, the depth of the sealing groove 171 can be designed to be 1 mm, 2 mm, or 3 mm. The specific requirements determine the appropriate groove depth to improve the sealing effect and installation stability. In addition, when the depth of the sealing groove 171 is too shallow, it may lead to insufficient sealing performance, while too large a depth may increase production costs and assembly difficulties.

[0095] To further enhance the sealing performance, the sealing ring 170 can also be made of a variety of materials, such as silicone rubber, fluororubber, etc. The choice of specific materials will depend on the requirements of the use environment. For example, under the condition of high-temperature fluid, the chemical resistance of fluororubber will be better than that of ordinary silicone rubber, ensuring stable performance during long-term use.

[0096] In one embodiment, there is a gap between the end of the water guide plate 330 and the inner wall of the housing structure 100. With this arrangement, a space for conveying water droplets can be formed between the water guide plate 330 and the inner wall of the housing structure 100, thereby effectively guiding the water droplets to flow from the water guide plate 330 to the bottom of the housing structure 100 to prevent water droplets from accumulating inside the housing and improving the waterproof performance.

[0097] In some embodiments, to further accelerate the diversion speed of the water droplets, the gap between the water guide plate 330 and the inner wall of the housing structure 100 can be set to be between 1 mm and 5 mm. Specifically, the gap can be 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm. The size of the gap needs to be determined according to the actual design requirements and is not uniquely limited here. When the gap is too large, although the diversion speed will increase, it may cause more splashing of the water droplets during the diversion process, thus affecting the diversion effect. When the gap is too small, it may cause an increase in the friction force between the water guide plate 330 and the inner wall of the housing structure 100, resulting in a reduction in the diversion effect.

[0098] Furthermore, the front panel 120 is provided with a positioning groove 122, and the side of the sealing ring 170 away from the middle frame structure 300 is inserted into the positioning groove 122.

[0099] In this embodiment, by providing the positioning groove 122 on the front panel 120, the installation of the sealing ring 170 can be effectively positioned, improving the convenience and accuracy of installation. Specifically, the design of the positioning groove 122 enables the sealing ring 170 to be stably embedded in the groove during the installation process, avoiding installation deviations caused by manual operation, thereby ensuring the stability of the sealing performance. This design not only reduces the complexity of the installation process, but also helps to improve production efficiency and reduces the subsequent maintenance costs caused by incorrect installation.

[0100] The shape and size of the positioning groove 122 can be optimized according to actual requirements. Specifically, it can be designed into a U shape, a V shape or other suitable shapes to adapt to different types of sealing rings 170. In engineering applications, the appropriate groove depth needs to be selected according to the thickness of the sealing ring 170 and the elasticity of the material to ensure that the sealing ring 170 can be firmly fixed in the groove while not affecting its ability of elastic deformation. It should be noted that the groove depth can be designed as 3mm, 5mm or 7mm, which is specifically determined according to actual design requirements and will not be uniformly limited here.

[0101] In addition, the setting of the positioning groove 122 also allows multiple groove positions to be set in the same front panel 120 to support the configuration of multiple sealing rings 170. Specifically, the number of the sealing rings 170 can be one, two or more than two. In the case of using multiple sealing rings 170, a more effective multiple seal can be formed, thereby greatly improving the overall sealing performance and reducing the risk of liquid leakage.

[0102] Specifically, the filter element housing 310 includes a first housing 311 and a second housing 312. The first housing 311 is connected to the second housing 312. The accommodating cavity includes a first accommodating cavity 3111 and a second accommodating cavity 3121. The first accommodating cavity 3111 is arranged in the first housing 311, and the second accommodating cavity 3121 is arranged in the second housing 312. The filter element assembly 500 includes a first filter element 510 and a second filter element 520. The first filter element 510 passes through the first accommodating cavity 3111 and is connected to the water circuit assembly 210. The second filter element 520 passes through the second accommodating cavity 3121 and is connected to the water circuit assembly 210, and the first filter element 510 and the second filter element 520 are communicated through the water circuit assembly 210; in some embodiments, the middle frame structure 300 further includes a mounting housing 320, and the first housing 311 and the second housing 312 are respectively connected to the mounting housing 320, and a placement cavity 321 is arranged in the mounting housing 320.

[0103] In this embodiment, by combining the first housing 311 and the second housing 312 to form the double-barrel middle frame structure 300, the effective management of multiple filter element assemblies 500 can be realized. Specifically, the first housing 311 and the second housing 312 can respectively install the first filter element 510 and the second filter element 520. This design scheme is convenient for realizing various filtering functions of the water purifier 10 and helps to meet the purification requirements of different water qualities. It should be noted that the number of filter elements can be one, two or more than two, which is selected according to actual filtering requirements. For example, when using two filter elements, targeted filtration can be carried out for different pollutants, greatly improving the purity and use safety of the water quality.

[0104] Meanwhile, the installation frame 320 is spaced from the first accommodation cavity 3111 and the second accommodation cavity 3121 for installing the booster pump 410 and the power adapter 420, and can also achieve water and electricity separation, thereby improving the use safety and reliability of the water purifier 10.

[0105] In this embodiment, the electrical component 220 can be disposed between the first frame 311 and the second frame 312. This configuration not only effectively saves space, but also improves the overall structural compactness of the water purifier 10, helps to simplify the assembly process and reduce the production cost. At the same time, the electrical component 220 being set at this position also makes its cooperation with the filter element assembly 500 more reasonable, thereby improving the working efficiency of the device.

[0106] Specifically, the drain holes include a first drain hole 3112 and a second drain hole 3122. The first drain hole 3112 is provided on the first frame 311 and communicates with the first accommodation cavity 3111, and the second drain hole 3122 is provided on the second frame 312 and connects to the second accommodation cavity 3121; the first frame 311 is located on top of the second frame 312.

[0107] In this embodiment, the water guide plate 330 is connected to the first frame 311, so that when the water guide plate 330 guides out water droplets, it can effectively shield the electrical component 220 on the lower side of the first frame 311, thereby preventing the influence of water droplets on the electrical component 220. This has a significant effect on improving the reliability and service life of the water purifier 10, avoiding electrical failures caused by water droplet intrusion. At the same time, this design also facilitates maintenance and reduces cleaning problems caused by water accumulation.

[0108] Of course, in some embodiments, the second frame 312 can also be provided with a water guide plate 330 at the same time to effectively guide the water droplets inside the second frame 312. This improvement measure can enhance the overall waterproof performance, especially in the case of water droplets and steam generated by the water flow and filtration action in the filter element assembly 500, which helps to improve the operation stability of the device and further ensure the safety of the electrical component 220.

[0109] It should be noted that the material and shape of the water guide plate 330 can be designed according to actual needs. The water guide plate 330 can be made of stainless steel, plastic or other corrosion-resistant materials. In specific implementations, the material selection should consider factors such as the use environment and cost. For example, choosing a stainless steel water guide plate 330 can increase its durability and corrosion resistance, while using lightweight plastic can reduce the manufacturing cost and the weight of the device.

[0110] In one embodiment, the first drain hole 3112 is located on the side close to the waterway assembly 210. By arranging the first drain hole 3112 on the side close to the waterway assembly 210, the water droplets generated when the filter element assembly 500 is separated from the waterway assembly 210 can be discharged from the first accommodation cavity 3111 through the first drain hole 3112 more quickly. This design greatly improves the liquid drainage efficiency of the first housing 311, ensures the rapid discharge of moisture, and further reduces the risk of water accumulation and potential leakage.

[0111] In addition, the setting position of the first drain hole 3112 also facilitates the maintenance personnel to quickly clean the accumulated water when replacing the filter element assembly 500, minimizing the maintenance time and operation complexity. It should be noted that the first drain hole 3112 can be a round hole with a diameter of 4 mm, 5 mm or 6 mm, or a rectangular hole to adapt to different drainage requirements and flow conditions. It is specifically determined according to the actual design requirements and is not uniquely limited here.

[0112] Furthermore, the first drain hole 3112 is respectively communicated with the end face of the first accommodation cavity 3111 facing the waterway assembly 210 and the inner wall surface of the first accommodation cavity 3111. Such a design enables the opening of the first drain hole 3112 to cover multiple directions, effectively expanding its drainage channel.

[0113] In this embodiment, by setting the opening of the first drain hole 3112 to be respectively communicated with the two end faces of the first accommodation cavity 3111, the opening area of the first drain hole 3112 can be increased, thereby improving the liquid drainage efficiency. A larger opening area can significantly reduce the resistance of the water flow, help the water droplets to be discharged more quickly, and avoid potential problems caused by the accumulation of water droplets, such as equipment corrosion or failure. Furthermore, the increased drainage area can also better cope with the amount of water that may be generated during the cleaning or maintenance process, improving the operation convenience of the equipment.

[0114] Specifically, the electrical component 220 includes at least one of a solenoid valve 221, a temperature sensor 222, a high-pressure switch 223, a flow meter 224, and a water quality sensor 225. Specifically, the liquid pump can be a gear pump, a centrifugal pump, or a plunger pump to adapt to different flow requirements. The gear pump generates liquid flow by rotating gears and has the advantages of simple structure and stable operation; the centrifugal pump is suitable for high-flow and low-pressure applications and can efficiently transport liquids; while the plunger pump is suitable for high-pressure environments and can work under strict flow control. Therefore, by selecting the appropriate type of liquid pump, the best liquid transportation effect can be achieved according to the actual needs of the system.

[0115] The solenoid valve 221 is used to control the on / off of the water circuit in the water circuit assembly 210, or to switch between multiple water circuits. The solenoid valve 221 can be designed as normally closed or normally open to meet different control requirements. For example, the normally closed solenoid valve 221 remains closed when not powered, which is suitable for safety control, while the normally open solenoid valve 221 remains open when not powered, which is suitable for applications that require continuous flow. Such a flexible choice can effectively improve the intelligent management level of the water circuit system.

[0116] The temperature sensor 222 is used to obtain the temperature of the water flow in the water circuit assembly 210. Common types include thermocouples, thermistors, etc. Assuming a thermocouple is selected, it has a fast response time and a wide measurement range, and is suitable for use in high-temperature environments; while the thermistor is very suitable for applications with low temperature and precise temperature measurement. Selecting the appropriate sensor type according to different temperature measurement requirements helps to ensure the accuracy of the system in temperature monitoring.

[0117] The high-pressure switch 223 is used to obtain the pressure of the water circuit in the water circuit assembly 210 and perform feedback control. Specifically, the high-pressure switch 223 can be designed as mechanical or electronic. The mechanical high-pressure switch 223 is suitable for relatively simple applications and has the advantage of high reliability; while the electronic high-pressure switch 223 provides better accuracy and flexibility, and can provide richer alarm functions and data interfaces. Reasonably selecting the type of high-pressure switch 223 according to the actual application requirements can achieve higher safety and control flexibility.

[0118] The flowmeter 224 is used to obtain water flow signals such as the water flow rate and water flow velocity in the water circuit assembly 210. The flowmeter 224 can adopt various designs such as float type, turbine type or electromagnetic type. The float type flowmeter 224 is suitable for measuring low-viscosity fluids such as clear water and has a simple structure; the turbine type flowmeter 224 has a fast response speed and is suitable for medium flow measurement; while the electromagnetic flowmeter 224 can be used for measuring the flow rate of conductive liquids and has a wide range of applications. Therefore, selecting different types of flowmeters 224 according to the characteristics of the liquid and the measurement conditions can effectively improve the accuracy and applicability of the measurement.

[0119] The water quality sensor 225 is used to obtain the water quality signal in the water circuit assembly 210. Specifically, the water quality sensor 225 can monitor the state and parameters of the water quality, such as pH value, conductivity and turbidity, etc. The water quality sensor 225 can adopt various types such as electrochemical sensors, optical sensors or ultrasonic sensors. Electrochemical sensors are suitable for monitoring pH value and conductivity, optical sensors are suitable for monitoring turbidity, and ultrasonic sensors are suitable for monitoring flow rate and flow velocity. Specifically, the types of water quality sensors 225 can be flexibly selected according to actual needs to meet different water quality monitoring requirements.

[0120] In summary, by reasonably configuring various components in the electrical component 220, the liquid transportation, control, and monitoring efficiency of the waterway component 210 can be comprehensively improved, thereby enhancing the intelligence and automation level of the entire water purifier 10 and ensuring its stability and reliability in different working scenarios.

[0121] In one embodiment, the structural design of the filter element assembly 500 aims to improve the filtration efficiency and water quality safety of the water treatment system. The first filter element 510 includes a primary filter element, and the second filter element 520 includes an RO filter element. The primary filter element is directly connected to the waterway device 200 and communicates with the first interface 2116 of the waterway component 210 in the waterway device 200. This configuration enables the primary filter element to effectively remove large particulate impurities and suspended solids in the water, thereby protecting the subsequent RO filter element from damage and extending its service life.

[0122] At the same time, the RO filter element is connected to the waterway device 200 and is connected to the second interface 2124 of the waterway component 210 in the waterway device 200, and the first interface 2116 and the second interface 2124 are connected through the waterway flow channel in the waterway component 210. Through this design, the RO filter element can efficiently further filter the water flow after primary filtration to remove fine dissolved substances and harmful substances, ensuring that the final water quality meets the drinking standard. The design of the connecting pipe 230 is used to continuously transport the water flow output by the primary filter element to the RO filter element. This setting of the flow path can not only improve the overall filtration efficiency of the system but also further reduce the pollution risk during the water flow transfer process.

[0123] In terms of specific implementation, the primary filter element can adopt various filter materials, such as polypropylene, polyester, etc., with good filtration performance and corrosion resistance; while the RO filter element is preferably made of reverse osmosis membrane material, which has excellent separation ability and is suitable for desalination and removal of microorganisms. At the same time, the material selection of the connecting pipe 230 can be adjusted according to specific application requirements. For example, a food-grade plastic pipe is selected, which is not only economical and practical but also ensures water quality safety.

[0124] Furthermore, the pressurizing device 400 further includes a buffer assembly 430. The buffer assembly 430 includes a connection structure 431 and a buffer member 432. The pressurizing pump 410 is accommodated in the placement cavity 321 and is connected to the connection structure 431, and the connection structure 431 is connected to the middle frame structure 300 through the buffer member 432.

[0125] In this embodiment, the water purifier 10 significantly improves the noise problem during the use of the existing water purifier 10 by arranging a buffer assembly 430 between the booster pump 410 and the middle frame structure 300. In the prior art, due to the lack of effective shock absorption design, the friction and vibration generated by the booster pump 410 during operation not only directly lead to an increase in noise, but also may cause resonance, easily resulting in the loosening of the filter element, affecting the user experience, and seriously damaging other components of the water purifier 10 in severe cases.

[0126] Applying the technical solution of the water purifier 10 in this embodiment, the application of the buffer assembly 430 effectively absorbs the vibration generated when the booster pump 410 works, reducing the noise level. This design greatly improves the sound insulation effect of the water purifier 10 while ensuring the performance of the booster pump 410. In addition, the design of the buffer assembly 430 can prevent the spread of noise, improve the overall service life of the water purifier 10, and effectively solve multiple problems caused by vibration and noise in the prior art water purifier 10.

[0127] Specifically, the connection structure 431 includes a mounting seat 4311 and a carrier frame 4312. The mounting seat 4311 is connected to the middle frame structure 300. The buffer member 432 is rigidly connected to the mounting seat 4311 through a connecting screw 440. At the same time, the buffer member 432 is connected to the carrier frame 4312 in a flexible connection manner. The carrier frame 4312 is connected to the booster pump 410, and the booster pump 410 is spaced from the inner wall of the placement cavity 321.

[0128] This design solution enables, when assembling the booster device 400 of this embodiment, first fixing the booster pump 410 on the carrier frame 4312, and then connecting the carrier frame 4312 to the mounting seat 4311 through the buffer member 432 to form an integral modular structure. This modular design is not only convenient for disassembly and assembly, but also improves the assembly efficiency, providing convenience for later maintenance.

[0129] When the booster pump 410 generates vibration, the vibration will be conducted through the connection to the carrier frame 4312. Since the carrier frame 4312 and the mounting seat 4311 are connected through the buffer member 432, the buffer member 432 can play a shock-absorbing role between the carrier frame 4312 and the mounting seat 4311, thereby effectively reducing the conduction of vibration and significantly reducing the generation of noise. This buffer connection design ensures the overall stability of the booster device 400, avoiding subsequent problems caused by the vibration of the booster pump 410, such as component damage or shortened service life.

[0130] It should be emphasized that the connecting screw 440 can be in various forms such as screws and pins, and the specific implementation method should be selected according to the actual product design requirements. In different application scenarios, selecting different types of connecting screws 440 can provide a more flexible connection method and better stability. Setting multiple connecting screws 440 can further enhance the firmness of the connection and seismic performance. Specifically, the number of connecting screws 440 can be one, two, or more, which is not uniquely defined here. In addition, the material of the buffer 432 can be silicone rubber, foam material, etc., and the specific selection should be based on the actual design requirements to ensure the best shock absorption effect.

[0131] In one embodiment, the design of the buffer 432 includes a buffer connection part 4321, a buffer bearing part 4322, and a flexible buffer support part 4323. Among them, the buffer support part 4323 abuts against the mounting seat 4311 to provide support and shock absorption; the buffer bearing part 4322 is mainly used to support the bottom of the carrier 4312, thereby ensuring the stability of the overall structure. The carrier 4312 is provided with a connection notch 43121, and the buffer connection part 4321 is provided with a buffer connection groove 43211. The buffer connection part 4321 passes through the connection notch 43121 to ensure that the carrier 4312 can be locked in the buffer connection groove 43211 to form a firm connection.

[0132] Through the above settings, the buffer bearing part 4322 can effectively support the connection with the carrier 4312. The buffer connection part 4321, through its cooperation with the carrier 4312, realizes the shock absorption effect on the vibration conduction between the carrier 4312 and the mounting seat 4311. In the specific implementation method, the buffer 432 can be rigidly connected to the mounting seat 4311 by screws to ensure its fixed stability. The advantage of this rigid connection method is that the screws have good tensile and shear strength and can withstand a certain amount of external impact, which is suitable for use in a vibrating environment.

[0133] In this configuration, a flexible connection is adopted between the buffer connection part 4321 and the carrier 4312, which enables the buffer connection part 4321 to effectively absorb and reduce the impact of vibration on the carrier 4312 when the booster pump 410 vibrates. At the same time, by clamping the carrier 4312 into the buffer connection groove 43211 of the buffer connection part 4321 through the connection notch 43121, the positioning effect formed avoids the separation of the buffer 432 and the carrier 4312 in the vibrating state, further enhancing the reliability and durability of the design.

[0134] It should be noted that different types of screws can be selected, such as cross-head, hexagon socket head, or self-tapping screws, etc., which can be adjusted according to specific assembly requirements. This is not uniquely defined here. Selecting the appropriate fasteners not only enhances the firmness of the connection but also improves the convenience of assembly and maintenance.

[0135] The connection structure 431 between the buffer connection part 4321 and the carrier 4312 can adopt various variants in this embodiment, such as snap connection or plug connection, thereby further improving the shock absorption effect and realizing the adaptability to common vibration.

[0136] Furthermore, the buffer connection part 4321 is also provided with a buffer protrusion 43212. The buffer protrusion 43212 protrudes from the side of the buffer connection part 4321 away from the buffer support part 4323. At least part of the fastener is spaced from the buffer connection part 4321 and abuts against the buffer protrusion 43212. In this embodiment, the buffer protrusion 43212 can effectively abut against the head of the connecting screw 440. Therefore, on the premise of ensuring the connection between the connecting screw 440 and the buffer part 432, the deformation space of the buffer part 432 can be effectively increased. This design not only reduces the contact area between the buffer part 432 and the connecting screw 440, avoiding affecting the shock absorption effect due to excessive contact, but also enables the buffer part 432 to deform and recover better when subjected to external vibration, thereby improving the overall shock absorption effect.

[0137] It should be noted that the fastener can be selected in various forms, such as screws, pins or nuts, etc. In specific implementation, the type of screw should be adjusted according to the required connection strength and environmental adaptability. For example, if high-strength screws are selected, the rigidity and stability of the connection can be increased, thereby enhancing the seismic performance of the structure. Specifically, the specifications of the screws can be selected according to the specifications of the mounting seat 4311. At the same time, the space and force conditions of the connection part should also be considered during the design selection process. Such a selection can effectively guarantee the reliability of the system.

[0138] Generally speaking, through the design of the buffer protrusion 43212, the deformation ability of the buffer part 432 can be improved while adding fasteners, thereby enhancing the shock absorption effect. This not only improves the stability of the supercharging device 400 during operation, but also helps to extend the service life of the system and reduce the maintenance cost.

[0139] In one embodiment, the connection notch 43121 includes a communicating guiding groove part 43122 and a connection groove part 43123. The buffer connection part 4321 penetrates through the connection groove part 43123. The guiding groove part 43122 penetrates the edge of the carrier 4312, and the opening on the side of the guiding groove part 43122 away from the connection groove part 43123 is in a horn shape.

[0140] With this setting, when the carrier 4312 is connected to the buffer connection part 4321, the guide groove part 43122 first contacts the buffer connection part 4321. Since the guide groove part 43122 is in a flared shape and has the characteristic of inclined plane guiding, it can effectively guide the buffer connection part 4321 to accurately enter the connection slot 43121. This structure can not only improve the installation accuracy between the carrier 4312 and the buffer 432, ensure a tighter fit between components, but also help improve the convenience of the assembly process and reduce the occurrence of installation difficulties or errors caused by inaccurate alignment.

[0141] In the specific implementation, the opening design of the guide groove part 43122 can adopt different angles or flared expansion degrees, and the most suitable angle is specifically selected according to the actual situation to further optimize the guiding effect. This flexibility can improve the assembly efficiency of the production line and adapt to various application environments. In an embodiment, the middle frame structure 300 is further provided with a receiving slot 3211, the receiving slot 3211 communicates with the placement cavity 321 and protrudes outward from the placement cavity 321, and at least part of the connection structure 431 is inserted into the receiving slot 3211, and its design aims to enhance the fit and assembly accuracy between components.

[0142] By setting the cooperation between the receiving slot 3211 and the connection structure 431, when assembling the connection structure 431, the connection structure 431 can be first inserted into the receiving slot 3211. This design provides a good positioning effect, reduces the difficulty of alignment during assembly, improves the convenience and accuracy of the overall connection, and ensures that the connection structure 431 can be fixed at a predetermined position.

[0143] In a specific embodiment, the mounting seat 4311 can be inserted and matched with the receiving slot 3211, thereby further improving the connection accuracy between the mounting seat 4311 and the middle frame structure 300. In summary, through the effective cooperation between the receiving slot 3211 and the connection structure 431, and the insertion design of the mounting seat 4311 and the receiving slot 3211, not only the assembly connection accuracy is improved, but also the connection method can be flexibly selected according to the actual design requirements to ensure the overall performance and reliability of the middle frame structure 300.

[0144] Specifically, the middle frame structure 300 is provided with a connecting frame 323, and the connecting frame 323 is arranged on the inner wall of the placement cavity 321 and protrudes towards the inside of the placement cavity 321; the middle frame structure 300 is provided with a first strip-shaped hole 3212 communicating with the accommodation notch 3211, and the connecting structure 431 is provided with a second strip-shaped hole 43111. The first strip-shaped hole 3212 is movably connected to the connecting structure 431 through a fastener, and the second strip-shaped hole 43111 is movably connected to the middle frame structure 300 through a fastener. In this embodiment, the fastener is connected to the mounting seat 4311 through the first strip-shaped hole 3212, and the mounting seat 4311 is connected to the connecting frame 323 through the second strip-shaped hole 43111, and the first strip-shaped hole 3212 and the second strip-shaped hole 43111 are designed to be parallel. This design allows the mounting seat 4311 to move relatively in the length direction parallel to the first strip-shaped hole 3212, facilitating the adjustment of the actual mounting position of the mounting seat 4311.

[0145] The connecting frame 323 extends from the bottom surface of the placement cavity 321 towards the inside. At the same time, the design allows the mounting seat 4311 to cover the connecting frame 323. In this design case, the fastener passes through the second strip-shaped hole 43111 from the outside of the mounting seat 4311 and is connected to the connecting frame 323. This layout not only makes the combination of the mounting seat 4311 and the middle frame structure 300 more compact but also helps to improve the space utilization efficiency. In addition, the setting of the mounting seat 4311 plays a certain protective role for the connecting frame 323, improving the connection reliability between the mounting seat 4311 and the middle frame structure 300.

[0146] It should be noted that various forms of fasteners can be selected, such as screws, pins, etc. In this regard, the selection of screws may bring better tensile strength and stability and is suitable for situations that need to bear large loads, while pins have advantages in rapid assembly and maintenance for later maintenance. In addition, considering the specific design requirements of the connecting structure 431, the number of fasteners can depend on the application scenario. Usually, choosing one, two or more is not uniquely limited here. The connection with multiple fasteners may enhance the overall connection firmness and durability, thus improving the reliability and safety of the equipment.

[0147] Furthermore, the middle frame structure 300 is also provided with a positioning convex block 324, and a positioning accommodation groove 43112 is opened at the edge of the connecting structure 431. The positioning accommodation groove 43112 is engaged with the positioning convex part 21212. This design enables the positioning accommodation groove 43112 on the mounting seat 4311 to be firmly combined with the positioning convex block 324 on the middle frame structure 300 when the mounting seat 4311 is connected to the middle frame structure 300, thus realizing the accurate position positioning of the mounting seat 4311.

[0148] Specifically, the positioning receiving groove 43112 is designed in an arc shape, and the outer wall of the positioning bump 324 is also in an arc shape. This structure enables the positioning receiving groove 43112 to closely fit with the positioning bump 324, achieving a highly accurate positioning effect. This design can reduce assembly errors during the assembly process and ensure the mutual cooperation between components.

[0149] Of course, in some embodiments, the mounting seat 4311 can choose not to be provided with the positioning receiving groove 43112. In this case, contact will be established between its straight edge and the arc-shaped positioning bump 324. In this situation, a line contact or point contact will be formed between the mounting seat 4311 and the positioning bump 324, which helps to reduce the contact area between the two, thereby improving the vibration propagation effect and further enhancing the shock absorption performance of the buffer assembly 430. By reducing the contact area, the vibration will be effectively attenuated during transmission, thus better protecting the booster pump 410 and its related components and reducing the potential damage risk caused by vibration.

[0150] It is worth mentioning that in specific implementations, the shape of the positioning receiving groove 43112 can take various forms, such as a U-shaped groove, an elliptical groove, etc., which can all meet the accuracy requirements of different design needs. There is no unique limitation here. Selecting an appropriate notch design will help improve the positioning accuracy and connection stability, effectively avoiding subsequent problems caused by improper assembly.

[0151] Furthermore, the buffer assembly 430 further includes a flexible buffer pad 433, and the buffer pad 433 is disposed between the connection structure 431 and the middle frame structure 300. By providing the buffer pad 433 between the mounting seat 4311 and the middle frame structure 300, the overall buffer effect of the buffer assembly 430 is effectively improved. In specific implementations, the buffer pad 433 can be made of various materials, such as rubber, silica gel or other elastic materials, to adapt to different application requirements.

[0152] The buffer pad 433 made of a flexible material can effectively absorb and mitigate the acting forces brought by vibration and impact, which has obvious advantages in improving the overall durability and stability of the device. By selecting appropriate buffer materials, the vibration propagation can be improved to a great extent, reducing the damage risk to the middle frame structure 300 and related components.

[0153] In addition, the shape and size of the buffer pad 433 can also be customized according to specific requirements to ensure that it can perfectly match the space between the connection structure 431 and the middle frame structure 300, forming effective contact and close fit. It is conceivable to use multiple buffer pads 433 to further enhance the overall buffer effect. Specifically, the number of buffer pads 433 can be one, two or more than two. There is no unique limitation here. This can not only increase the contact area but also disperse the acting forces, thereby achieving a more efficient shock absorption effect.

[0154] In one embodiment, the buffer pad 433 is provided with a bearing groove 4331, and the edge of the connecting structure 431 is inserted into the bearing groove 4331.

[0155] By providing the bearing groove 4331 in the buffer pad 433, when the mounting seat 4311 is connected to the buffer pad 433, it can be smoothly inserted and fixed in the bearing groove 4331. This not only helps to accurately position the mounting seat 4311 but also ensures the stability of the buffer pad 433 during the installation process. When the mounting seat 4311 presses the buffer pad 433 into the placement cavity 321, the design of the bearing groove 4331 can provide an additional limiting function to prevent the buffer pad 433 from accidentally detaching due to vibration. This limiting effect significantly improves the safety of the overall structure and ensures the stable combination of components under various operating conditions.

[0156] It should be noted that the shape and size of the bearing groove 4331 can be adjusted according to specific design requirements. Common shapes can be U-shaped, V-shaped, or linear, and the specific implementation is not uniquely limited. This flexibility is beneficial for meeting the installation requirements of different devices and can also improve the buffering efficiency to a certain extent.

[0157] In one embodiment, the middle frame structure 300 further includes a limiting plate 322, and the limiting plate 322 is arranged on one side of the connecting structure 431 in the axial direction of the accommodating cavity. By setting the cooperation between the limiting plate 322 and the mounting seat 4311, the limiting plate 322 can effectively limit the installation position of the mounting seat 4311 in the placement cavity 321. When the mounting seat 4311 is installed in place, the limiting plate 322 can abut against the outer wall of the mounting seat 4311, thereby stably limiting it in the direction perpendicular to the limiting plate 322. This design ensures the stability and accuracy of the components in the working state.

[0158] In addition, in some embodiments, the number of the limiting plates 322 can be multiple, such as two, three, or more. When multiple limiting plates 322 are arranged at intervals, the installation positions formed between adjacent limiting plates 322 can be used to accommodate the mounting seat 4311. This configuration of multiple limiting plates 322 not only enhances the multiple limiting effect on the mounting seat 4311 but also improves its adaptability under different installation conditions, thereby further improving the reliability of the structure.

[0159] It should be noted that the design of the limit plate 322 does not require continuous contact with the entire side wall of the mounting seat 4311. The limit plate 322 can contact the mounting seat 4311 when the mounting seat 4311 deviates from the preset installation position, while when the mounting seat 4311 is in the preset position, the limit plate 322 is spaced from it. This flexible configuration not only facilitates plugging and maintenance during daily operations but also reduces wear caused by contact friction, contributing to extending the service life of the overall structure.

[0160] In addition, through different implementation manners, the material of the specific limit plate 322 can be set. For example, materials such as plastic, aluminum alloy, or stainless steel can be selected. These materials have their own advantages in terms of strength, corrosion resistance, and wear resistance. Specifically, using plastic as the limit plate 322 is not only light and easy to process but also has excellent corrosion resistance. At the same time, it can be directly formed on the placement cavity 321 when the middle frame structure 300 is injection-molded; while aluminum alloy and stainless steel perform excellently in terms of strength and durability, especially suitable for occasions that bear greater mechanical pressure. This makes the application scenarios of the limit plate 322 more extensive, and the material can be flexibly selected according to actual design requirements.

[0161] Furthermore, the waterway assembly 210 includes a first waterway plate 211 and a second waterway plate 212. The first waterway plate 211 is provided with a connection groove 2111, and a plug-in portion 2112 is formed on the outside of the connection groove 2111; one end of the second waterway plate 212 is provided with a mounting portion 2121, and a mounting groove 2122 is formed on the outside of the mounting portion 2121. The mounting portion 2121 is inserted into the connection groove 2111, and the plug-in portion 2112 is inserted into the mounting groove 2122; wherein, the first waterway plate 211 and the second waterway plate 212 are communicated with each other to form a waterway flow channel for conveying water flow.

[0162] In the waterway device 200 of this embodiment, by dividing the waterway assembly 210 into the first waterway plate 211 and the second waterway plate 212, a modular design structure is constructed, thus effectively solving the problems of high cost and low efficiency faced by the integrally formed waterway plate in the prior art.

[0163] During the manufacturing process, the modular design can reduce production costs and improve processing efficiency by simplifying the complexity of the mold. This split structure can not only reduce material waste but also shorten the manufacturing cycle, significantly improving economy and processability.

[0164] Meanwhile, the design of the waterway device 200 also particularly considers the convenience of later maintenance. Since the first waterway plate 211 and the second waterway plate 212 are connected by means of plugging and accommodating, if a certain component is damaged during later use, only the corresponding waterway plate needs to be replaced, rather than the whole being replaced, thus reducing the maintenance cost. This detachable connection method enhances the maintainability and usage flexibility of the waterway device 200, ensuring the sustainability of the overall system usage. Additionally, by setting the cooperation between the connection groove 2111 and the installation part 2121, as well as the cooperation between the plugging part 2112 and the installation groove 2122, the first waterway plate 211 and the second waterway plate 212 can be accurately docked, and the disassembly and assembly are convenient.

[0165] In one embodiment, the connection groove 2111 includes an accommodation cavity 21111 and a positioning cavity 21112. The positioning cavity 21112 communicates with the accommodation cavity 21111, and the positioning cavity 21112 and the accommodation cavity 21111 form a stepped structure; the installation part 2121 includes an installation plate part 21211 and a positioning convex part 21212. The positioning convex part 21212 protrudes from the end of the installation plate part 21211. The installation plate part 21211 is inserted into the accommodation cavity 21111, and the positioning convex part 21212 is inserted into the positioning cavity 21112.

[0166] Firstly, the stepped structure can effectively position the insertion and installation of the first waterway plate 211 and the second waterway plate 212, thereby reducing the leakage risk caused by assembly errors to ensure the sealing and stability of the waterway flow channel formed by the combination of the first waterway plate 211 and the second waterway plate 212; secondly, the layered design makes the later disassembly and installation more convenient, simplifies the operation, and improves the maintenance efficiency.

[0167] Meanwhile, in the structure of the installation part 2121, there are an installation plate part 21211 and a positioning convex part 21212. The positioning convex part 21212 is provided at the end of the installation plate part 21211. The installation plate part 21211 is conveniently inserted into the accommodation cavity 21111, and the positioning convex part 21212 is inserted into the positioning cavity 21112. This design not only makes the connection between the first waterway plate 211 and the second waterway plate 212 more firm, ensuring that it will not become loose due to vibration or pressure during long-term use, but also increases the mating surface of the components, further enhancing the tensile strength and anti-torque performance. Therefore, the waterway device 200 adopting this structure shows better durability and reliability in practical applications, meeting the high standards required by users for the water purifier 10.

[0168] Furthermore, the number of positioning cavities 21112 is at least two, and two of the positioning cavities 21112 are respectively arranged on opposite sides of the accommodating cavity 21111; the number of positioning protrusions 21212 is at least two, and two of the positioning protrusions 21212 are respectively arranged on opposite sides of the mounting plate portion 21211, and at least two of the positioning protrusions 21212 are respectively inserted and cooperated with the two positioning cavities 21112.

[0169] With this arrangement, the cooperation between the connecting groove 2111 and the mounting portion 2121 can effectively disperse the stress on each connecting point, reducing damage or loosening caused by excessive local stress. At the same time, through the cooperation of multiple positioning cavities 21112 and positioning protrusions 21212, the anti-fool installation function between the first waterway plate 211 and the second waterway plate 212 can also be realized, effectively improving the assembly consistency of the waterway device 200, reducing the uncertainty caused by installation errors, and ensuring the tightness of the connection.

[0170] In addition, the number of positioning protrusions 21212 is also at least two, and these two positioning protrusions 21212 are respectively arranged on opposite sides of the mounting plate portion 21211. With such a design, at least two positioning protrusions 21212 can be inserted and cooperated with the two positioning cavities 21112, thereby effectively increasing the firmness of the connection and the anti-interference ability of the overall structure. The design of multiple positioning protrusions 21212 forms a more uniform clamping force among them, improving the stability of the connection, avoiding uneven pressure caused by a single contact point, and further optimizing the service life of the waterway device 200.

[0171] In the specific implementation manner, the positioning cavity 21112 can be made of plastic or metal materials to enhance its wear resistance and corrosion resistance; and the positioning protrusion 21212 can also be selected to be surface-treated with metal materials, such as galvanized or sprayed, to improve its rust prevention performance. The advantage of this design is that through the optimization of materials and the increase in quantity, the safety and durability of the waterway device 200 are significantly improved, meeting the user's demand for long-term stability. At the same time, the convenience of maintenance is improved, promoting the market competitiveness of the overall product.

[0172] Of course, in some embodiments, the number of the positioning cavities 21112 and the positioning protrusions 21212 can be two groups, three groups or more than three groups. By setting multiple groups of positioning cavities 21112 and positioning protrusions 21212 to cooperate, the connection accuracy and strength between the first waterway plate 211 and the second waterway plate 212 can be further improved.

[0173] Specifically, the first waterway plate 211 is further provided with a fixing hole 2113 communicating with the connecting groove 2111, and the second waterway plate 212 is provided with a connecting hole 2123 corresponding to the fixing hole 2113; the waterway device 200 further includes a fastener 213, and the fastener 213 passes through the fixing hole 2113 and is fixedly connected to the connecting hole 2123.

[0174] In the waterway device 200 of this embodiment, by adopting a split waterway plate structure, the combination of the first waterway plate 211 and the second waterway plate 212 enables the waterway device 200 to utilize simple molds and independent components during the production process, reducing the manufacturing complexity, thereby significantly improving the production efficiency and reducing material waste.

[0175] In addition, the design of the waterway device 200 of the present invention also takes into account the later maintenance and replacement issues. The detachable connection between the first waterway plate 211 and the second waterway plate 212 enables the user to only replace the specific waterway plate during system maintenance without replacing the entire waterway device 200, thereby reducing the maintenance cost and improving the user's convenience.

[0176] In one embodiment, the fixing hole 2113 includes a side through hole 21131 and a main through hole 21132. The side through hole 21131 is provided on the side wall of the first waterway plate 211, facilitating the insertion of the fastener 213 from the side through hole 21131 and fixing it to the connecting hole 2123 on the side of the second waterway plate 212. The main through hole 21132 is provided on the side adjacent to the side wall; the number of the fasteners 213 and the connecting holes 2123 is multiple, and each connecting hole 2123 corresponds to a fixing hole 2113 and is connected to the connecting hole 2123, enabling the fastener 213 to be adjusted more conveniently, ensuring the reliability and firmness of the connection. In addition, by arranging multiple fasteners 213 to cooperate with the connecting holes 2123, the connection strength between the first waterway plate 211 and the second waterway plate 212 can be further improved, so that the waterway device 200 has higher tensile strength and anti-vibration ability, and can effectively avoid the problem of loosening of the connection between the first waterway plate 211 and the second waterway plate 212 caused by water flow fluctuations.

[0177] Furthermore, the number of the main through holes 21132 is multiple, and the multiple main through holes 21132 are arranged at intervals on the second waterway plate 212. With this arrangement, the multiple connecting holes 2123 can be more evenly distributed on the entire second waterway plate 212, ensuring the connection reliability between the first waterway plate 211 and the second waterway plate 212 and avoiding local stress concentration.

[0178] In addition, the provision of multiple main through-holes 21132 enables the waterway device 200 to flexibly meet different installation requirements and space limitations during assembly. Users can freely select suitable connection points according to the specific usage environment, thereby realizing a customized installation plan, enhancing the adaptability and compatibility of the device. Specifically, the main through-holes 21132 can be provided on the second waterway board 212 by means of an injection molding process, which not only ensures the accuracy of the hole positions but also reduces the production cost.

[0179] This flexible spaced layout can also improve the structural strength of the whole machine, reduce the risk of failures that may be caused by improper connections, and thus enhance the reliability of the waterway device 200. At the same time, during the later maintenance process, users can individually disassemble and replace the fasteners 213 in the individual connection holes 2123 as needed, simplifying the maintenance process, saving the users' maintenance time and cost, and thus further enhancing the disassembly and assembly convenience of the waterway device 200.

[0180] In one embodiment, the number of main through-holes 21132 is three, and the three main through-holes 21132 are respectively provided corresponding to the vertices of a virtual triangle.

[0181] In this embodiment, the number of main through-holes 21132 is three, and the three main through-holes 21132 are respectively provided corresponding to the vertices of a virtual triangle. This configuration design can optimize the fluid flow path, improve the force uniformity of the fasteners 213, and contribute to ensuring the connection stability between the first waterway board 211 and the second waterway board 212.

[0182] In terms of specific implementation, the main through-holes 21132 can adopt different aperture and depth designs to adapt to the arrangement positions of different fixing holes 2113, so that the combined structure of the first waterway board 211 and the second waterway board 212 is more compact. According to actual needs, the material of the main through-holes 21132 can be selected as a material with strong corrosion resistance, such as stainless steel or engineering plastics, further improving the durability and adaptability of the waterway device 200, and thus extending the service life of the waterway device 200.

[0183] In addition, adopting a virtual triangle layout can, to a certain extent, reduce the stress concentration of the waterway device 200, improve the seismic resistance and stability of the waterway device 200. This design is also convenient for maintenance. When the operator removes the fastener 213 in any one of the fixing holes 2113, there are still other fasteners 213 connecting the first waterway board 211 and the second waterway board 212, reducing the maintenance time and cost.

[0184] Furthermore, the first waterway board 211 is further provided with an installation cavity 2114, the installation cavity 2114 communicates with the side through-hole 21131 and is provided outside the side through-hole 21131, and the outer opening of the installation cavity 2114 is flush with the side wall of the first waterway board 211.

[0185] In a specific embodiment, the installation cavity 2114 can be set to different depths and widths according to different actual application requirements. For example, the depth of the installation cavity 2114 can be designed to accommodate fasteners 213 of different specifications, so that when the fasteners 213 are installed, the fasteners 213 can be placed in the installation cavity 2114, avoiding damage caused by the fasteners 213 protruding outward and being impacted, and making the overall structure of the waterway device 200 more compact. At the same time, since the outer opening of the installation cavity 2114 is flush with the side wall, the appearance of the waterway assembly 210 is made neater. In addition, the internal structure of the installation cavity 2114 can be further optimized. For example, reinforcing ribs can be added to improve the strength of the installation cavity 2114 and enhance the strength and durability of the first waterway plate 211. Through such a design, the service life of the waterway device 200 can be effectively extended.

[0186] In one embodiment, the waterway device 200 further includes a connecting pipe 230. The connecting pipe 230 includes a pipe body 231 and a quick-release interface 232. Opposite ends of the pipe body 231 are each connected to a quick-release interface 232, and the pipe body 231 is respectively communicated with the first waterway plate 211 and the second waterway plate 212.

[0187] In the waterway device 200 of this embodiment, by using an external connecting pipe 230 to connect the first waterway plate 211 and the second waterway plate 212 respectively, the problems of complex internal waterway structure and high processing cost in the prior art can be solved. Compared with the traditional scheme of completely internal flow channels in the waterway plate, the design of the external pipeline significantly reduces the production difficulty and simplifies the manufacturing process, thereby effectively controlling the cost.

[0188] In terms of maintenance and cleaning, the external pipeline design brings further convenience. Since the connection between the connecting pipe 230 and the waterway device 200 is detachable, when the user needs to clean or replace the connecting pipe 230 in the equipment, it can be easily carried out without complex operations, reducing the maintenance cost.

[0189] In one embodiment, the pipe body 231 is a flexible pipe.

[0190] In terms of specific implementation, the flexible design of the pipe body 231 enables it to easily cope with space limitations and movement deformation in various installation environments, reduce stress concentration caused by hard connection, and at the same time reduce the potential risk of rupture. In addition, the use of the quick-release interface 232 further improves the operation convenience during the connection process. The user can quickly complete the connection and disconnection without complex tools, greatly optimizing the efficiency of maintenance and repair. This structural design is particularly suitable for occasions where the pipeline connection needs to be frequently replaced or adjusted. For example, during maintenance or equipment debugging, the user can quickly connect or disconnect the pipe body 231, saving time and labor costs.

[0191] Specifically, a first interface 2116 is provided on the first waterway plate 211, and a second interface 2124 is provided on the second waterway plate 212. One end of the pipe body 231 is communicated with the first interface 2116 through a quick-release interface 232, and the other end of the pipe body 231 is communicated with the second interface 2124 through the quick-release interface 232. At this time, by connecting the first waterway plate 211 and the second waterway plate 212, the overall waterway channel inside the waterway device 200 can be formed. The first waterway plate 211 and the second waterway plate 212 can be processed separately and combined to form an overall waterway, and then the first waterway plate 211 and the second waterway plate 212 are respectively connected through an external connecting pipe 230, which can achieve the purpose of reducing the overall manufacturing cost of the waterway device 200.

[0192] Further, the quick-release interface 232 includes an interface part and a sealing ring 170. The sealing ring 170 is arranged inside the first interface 2116, and the interface part is located outside the sealing ring 170 and is used for connecting with one end of the pipe body 231; the sealing ring 170 is arranged inside the second interface 2124, and the interface part is located outside the sealing ring 170 and is used for connecting with the other end of the pipe body 231.

[0193] In this embodiment, the design of the quick-release interface 232 further enhances the functionality and sealing performance of the connecting pipe 230, including the combination of the interface part and the sealing ring 170. During the assembly process, first, the sealing ring 170 is placed inside the first interface 2116, and then the interface part is covered outside the sealing ring 170. When the pipe body 231 is connected to the interface part, the interface part can seal the outside of the pipe body 231, and the sealing ring 170 can seal between the part of the pipe body 231 entering the first interface 2116 and the inner wall of the first interface 2116, thereby improving the sealing performance of the connecting pipe 230; similarly, the second interface 2124 is also connected to the pipe body 231 through the quick-release interface 232, which will not be elaborated here.

[0194] This design solution can effectively prevent liquid or gas leakage and improve the sealing effect of the connection by adopting the sealing ring 170 in the quick-release interface 232. The material of the sealing ring 170 can be selected from rubber, polyurethane or other materials with good elasticity and corrosion resistance to ensure excellent sealing performance under various working conditions. At the same time, the design of the interface part makes the fit between the pipe body 231 and the first interface 2116 and the second interface 2124 more stable, reducing the risk of connection loosening caused by external vibration.

[0195] In terms of specific implementation, the sealing ring 170 can adopt different shape designs, such as an O-ring or a flat washer; in production, it can meet the requirements of different pressure grades and medium conditions. Selecting the appropriate material and shape of the sealing ring 170 can not only further enhance the sealing performance of the connection, but also improve the heat resistance and chemical corrosion resistance, thereby extending the service life of the waterway device 200.

[0196] In one embodiment, the waterway device 200 further includes a connecting seat. The connecting seat is provided with a receiving groove. The connecting seat is disposed on one side of the first waterway plate 211 and / or the second waterway plate 212 facing the connecting pipe 230, and at least a part of the pipe body 231 is received in the receiving groove.

[0197] Specifically, the connecting seat protrudes from one side of the first waterway plate 211 and / or the second waterway plate 212 facing the connecting pipe 230, and the connecting seat is provided with a receiving groove. At least a part of the connecting pipe 230 is received in the receiving groove. The connecting seat is used to communicate with an external waterway.

[0198] In this embodiment, by providing a receiving groove on the connecting seat to cooperate with the connecting pipe 230, when the connecting pipe 230 is installed on the first waterway plate 211 and / or the second waterway plate 212, the connecting pipe 230 can be snapped into the receiving groove, and the installation of the connecting pipe 230 can be regularized and positioned through the receiving groove, so that the connecting pipe 230 can be laid on the surface of the waterway assembly 210 along a preset path, and at the same time, the combined structure of the connecting pipe 230 and the waterway device 200 can be made compact.

[0199] In this embodiment, by providing a connecting seat with a receiving groove to cooperate with the connecting pipe 230, when the connecting pipe 230 is installed on the waterway device 200, the connecting pipe 230 can be snapped into the receiving groove, and the installation of the connecting pipe 230 can be regularized and positioned through the receiving groove, so that the connecting pipe 230 can be laid on the surface of the waterway assembly 210 along a preset path, and at the same time, the combined structure of the connecting pipe 230 and the first waterway plate 211 and / or the second waterway plate 212 can be made compact.

[0200] In one embodiment, the waterway device 200 further includes a fixed baffle 240. The fixed baffle 240 is detachably connected to the connecting seat and covers the opening of the receiving groove. The design of the fixed baffle 240 is intended to achieve a detachable connection with the connecting seat and effectively cover the opening of the receiving groove. Through such a setting, the fixed baffle 240 can not only protect the connecting pipe 230 inside the receiving groove from the influence of the external environment and prevent the connecting pipe 230 from being damaged by being knocked.

[0201] During the assembly process, first snap the connecting pipe 230 into the receiving groove and position the connecting pipe 230 through the receiving groove. Then cover the fixed baffle 240 on the opening of the receiving groove and fixedly connect the fixed baffle 240 to the connecting seat, and the connection and fixation of the connecting pipe 230 and the waterway device 200 can be completed. On the contrary, when it is necessary to disassemble and assemble the connecting pipe 230, only need to separate the fixed baffle 240 from the connecting seat to release the connecting pipe 230.

[0202] In a preferred embodiment, a plurality of connectors are provided between the first interface 2116 and the second interface 2124. At this time, the connectors can be used to connect to external waterways such as external water sources and drainage pipelines. By cooperating with the connecting pipe 230 through the plurality of connectors, the connecting pipe 230 can be respectively accommodated in a plurality of receiving grooves, and the installation of the connecting pipe 230 can be positioned through the receiving grooves, improving the installation accuracy and at the same time improving the installation stability of the connecting pipe 230.

[0203] In terms of specific implementation, the fixed baffle 240 can be combined with the connector in a variety of connection methods such as bolts and buckles. When choosing bolt connection, higher sealing performance and stability can be ensured, which is suitable for occasions that need to withstand greater pressure or fluid impact. If buckle connection is adopted, faster disassembly and installation can be achieved, which is convenient for users to check and replace internal components during daily maintenance.

[0204] The use of the fixed baffle 240 not only improves the overall functionality and reliability of the waterway device 200, but also optimizes the operation experience of the entire waterway device 200. When users need to perform maintenance, they do not need to disassemble the entire waterway device 200. They only need to quickly remove the fixed baffle 240 to check or replace the connecting pipe 230, improving work efficiency.

[0205] Furthermore, the first waterway board 211 is also provided with a positioning portion 2115. The positioning portion 2115 includes a positioning card plate and a bracket. Both the positioning card plate and the bracket are connected to the side of the first waterway board 211 facing the connecting pipe 230, and the positioning card plate and the bracket are arranged around the pipe body 231.

[0206] Specifically, the inner diameter and shape of the positioning portion 2115 can be designed according to different specifications of the connecting pipe 230, aiming to achieve precise fit. When the positioning portion 2115 is connected to the connecting pipe 230, the connecting pipe 230 can also be supported. For example, the inner diameter of the positioning portion 2115 can be designed to match the outer diameter of the connecting pipe 230 so that they can be firmly clamped together. This design not only simplifies the installation process but also reduces potential risks caused by improper connection. In addition, the positioning portion 2115 can also adopt reinforced materials to improve its pressure resistance and durability, further enhancing the reliability of the waterway device 200.

[0207] Specifically, the positioning portion 2115 includes a positioning card plate and a bracket, forming a more stable connection solution. The bracket is arranged on the surface of the first waterway board 211, the positioning card plate extends outward from the first waterway board 211 and bends towards the bracket, and the positioning card plate and the bracket enclose a space for accommodating the connecting pipe 230.

[0208] When assembling the connecting pipe 230 of this embodiment, first attach the connecting pipe 230 to the surface of the first water circuit board 211 and make the connecting pipe 230 contact the bracket. At this time, the bracket can support the side of the connecting pipe 230 facing the first water circuit board 211. Then, snap the connecting pipe 230 into the inner side of the positioning card board. At this time, the positioning card board and the bracket respectively abut against the opposite sides of the connecting pipe 230, and the connecting pipe 230 can be fixed on the first water circuit board 211 to avoid the leakage risk caused by pipeline bending or dislocation, thereby improving the safety and reliability of the entire water circuit device 200.

[0209] In terms of specific implementation, the bracket and the positioning card board can also be made of a variety of materials such as plastic, metal or composite materials. These materials can not only provide sufficient mechanical strength, but also resist the corrosion of the external environment and extend the service life. For example, the positioning part 2115 made of corrosion-resistant synthetic materials can maintain good performance in a harsh water quality environment, thereby reducing the maintenance frequency and cost. In addition, this design is also convenient for installation and disassembly, which is beneficial to later maintenance and replacement, bringing a more convenient operation experience to users. When the positioning part 2115 is made of plastic, the positioning part 2115 can be directly formed on the first water circuit board 211 during the injection molding process of the first water circuit board 211 without additional assembly, and the structure is simple.

[0210] In this embodiment, for the connection requirements of the water circuit device 200, the fastener 213 can be a screw. As a common mechanical connector, a screw has the advantages of simple structure, easy installation and disassembly. Its feature is that it can form a strong clamping force through rotational movement to ensure the tight combination between the connecting parts, thereby effectively preventing loosening caused by vibration or external force.

[0211] In terms of specific implementation, the material of the screw can be selected as high-strength alloy steel or stainless steel, combined with surface treatment processes such as galvanizing or black oxidation treatment to improve its corrosion resistance and fatigue resistance. In addition, in order to further improve the connection effect, it can be considered to apply a thread locking agent to the thread part, which can reduce the loosening risk caused by temperature or environmental factors to a certain extent and ensure the long-term stable operation of the water circuit device 200.

[0212] In addition, the head design of the screw can adopt different forms such as a cross head or a hexagon head to meet the assembly requirements under different working conditions. This flexible design is not only convenient for construction workers to operate in a narrow space, but also can improve the assembly efficiency and reduce the labor intensity.
