Description

Technical Field

[0001] This utility model relates to the field of disinfection technology, and in particular to a disinfection filter structure and a water purifier. Background Technology

[0002] In traditional disinfection filter cartridge structures, there are generally two components: a disinfection structure and a filter cartridge housing. The stability of both the disinfection structure and the filter cartridge housing is crucial. However, traditional disinfection filter cartridge structures have the following drawbacks: they lack components for connecting the disinfection structure and the filter cartridge housing, or even if such components exist, they are prone to loosening due to vibration or pressure changes, affecting the reliability of the equipment. Utility Model Content

[0003] Therefore, it is necessary to provide a disinfection filter structure and water purifier to address the problem that traditional disinfection filter structures do not have components for connecting the disinfection structure and the filter housing, or that the connecting components are prone to loosening due to vibration or pressure changes, thus affecting the reliability of the equipment.

[0004] A disinfection filter structure includes: a housing assembly having a disinfection chamber and an assembly space communicating with the disinfection chamber; the housing assembly having a first port and a second port, both communicating with the disinfection chamber; one of the first port and the second port being used for water inlet and the other being used for water outlet; a disinfection component disposed on the housing assembly and located within the disinfection chamber; and a fastening component disposed on the housing assembly and passing through the assembly space, extending into the disinfection chamber after passing through the assembly space, the fastening component being used for connecting the disinfection component and the housing assembly.

[0005] The first aspect of this application discloses a disinfection filter structure. A disinfection component is disposed within a disinfection chamber, capable of disinfecting the liquid flowing through the chamber. The disinfection component can employ physical disinfection methods such as electrolysis, or chemical disinfection. A first and second inlet, for water inlet and outlet respectively, communicate with the disinfection chamber, ensuring smooth water flow. A fastening component penetrates the assembly space and extends into the disinfection chamber to cooperate with the disinfection component, forming a rigid connection between the disinfection component and the housing assembly. This effectively restricts the freedom of movement of the disinfection component and prevents relative displacement between the disinfection component and the housing assembly. This design avoids loosening problems caused by vibration or pressure changes, improving the overall structural reliability. Furthermore, the assembly space restricts the freedom of movement of the fastening component, resulting in a good fixation effect on the disinfection component.

[0006] In one embodiment, both the fastening component and the sterilization component are conductive. Power is supplied directly to the sterilization component via the conductive fastening component, eliminating the need for additional wiring connections, reducing the complexity of internal wiring layout, and improving structural compactness. This design allows the fastening component to integrate conductivity and fastening functions into one unit, resulting in a more ingenious design and improved utilization efficiency.

[0007] In one embodiment, there are multiple fastening components, all disposed on the housing assembly and located within the assembly space. These fastening components are used to connect the disinfection component and the housing assembly. By providing multiple fastening components, the disinfection component and the housing assembly have multiple points of connection, significantly improving the connection strength between them. This design avoids loosening problems caused by vibration or pressure changes, enhancing the overall structural reliability.

[0008] In one embodiment, the fastening assembly is made of a titanium-based material. By replacing traditional metal materials with titanium, water corrosion of the fastening assembly can be effectively avoided or reduced, thereby extending the service life of the equipment. The resistance to chloride ion corrosion using titanium-based materials is more than three times that of traditional stainless steel.

[0009] In one embodiment, the disinfection component is made of a titanium-based material. The disinfection component can be made of titanium-based materials, such as the electrodes of the disinfection component, with a surface coating of Ti-based Pt noble metal oxide anodes, achieving a balance between corrosion resistance and cost controllability of the filter device in chlorine-containing wastewater environments.

[0010] In one embodiment, the fastening assembly includes a conductive rod and a mating member. The conductive rod is disposed on the housing assembly and located in the assembly space, passing through the sterilization assembly. The mating member is disposed on the conductive rod and abuts against the sterilization assembly, applying a locking force to the sterilization assembly. The conductive rod enables both power transmission and component mating, simplifying the overall design. The combination of the mating member and the conductive rod allows for precise adjustment of the locking force applied to the sterilization assembly, ensuring a secure and reliable connection.

[0011] In one embodiment, a sealing element is further included, disposed on the conductive rod. The sealing element abuts against the disinfection assembly and the housing assembly, and is located between them. The sealing element and the mating element are respectively located at both ends of the disinfection assembly. By providing the sealing element, the disinfection assembly generates a continuous pre-tightening force when compressed by the mating element, causing the conductive rod, sealing element, and housing assembly to form a dynamic seal. This prevents water leakage from the assembly space within the disinfection chamber, with a sealing pressure fluctuation range of less than or equal to 15%. This design allows the sealing element and the mating element to work synergistically to compensate for gaps caused by thermal expansion and contraction and vibration. Preferably, the sealing element is made of silicone material.

[0012] In one embodiment, the conductive rod includes a connecting rod body and a connecting rod head. The connecting rod body is disposed on the housing assembly and located within the assembly space. The housing assembly has an adapter groove communicating with the assembly space. The connecting rod head is disposed on the connecting rod body and located at the adapter groove. The connecting rod head being located in the adapter groove makes the fastening assembly for securing the disinfection component more stable and reliable. Furthermore, the connecting rod head can engage with the water purifier's main unit using a conical surface, working in conjunction with a spring-loaded device on the main unit. This spring-loaded device, under stress, ensures the stability of the disinfection component after the main unit is powered on.

[0013] In one embodiment, the mating component includes a mating component body and a gasket, both of which are disposed on the conductive rod. The gasket is located between the mating component body and the disinfection assembly. By embedding the titanium-based gasket into the bottom conductive rod, the contact area between the gasket and the disinfection assembly is increased, thereby enhancing the stability and strength of the axial disinfection assembly. Preferably, the diameter of the gasket is three millimeters.

[0014] In one embodiment, the conductive rod is integrally injection molded with the housing assembly. Integrating the conductive rod with the housing assembly effectively improves the overall sealing function of the structure, thereby reducing the possibility of leakage. Furthermore, it effectively improves the installation efficiency of the internal electrode plates.

[0015] In one embodiment, the disinfection assembly includes a support base and an electrolysis module. The support base is disposed on the housing assembly and located within the disinfection chamber. The electrolysis module is disposed on the support base and is used for disinfecting the liquid. The support base provides a stable mounting foundation for the disinfection module, preventing displacement due to water flow impact or vibration. The placement of the disinfection module maintains a stable contact area with the liquid, ensuring uniform current distribution and improving electrolytic disinfection efficiency.

[0016] In one embodiment, the electrolysis module includes electrolytic plates and spacers. Multiple electrolytic plates are disposed on the support base, and multiple spacers are also disposed on the support base. The electrolytic plates and spacers are arranged alternately. The spacers effectively prevent adjacent electrolytic plates from contacting each other, thus preventing malfunction of the electrolysis sterilization function. During installation, the electrolytic plates and spacers are stacked sequentially layer by layer.

[0017] In one embodiment, there are multiple electrolysis modules, each consisting of a cathode module and an anode module. Multiple cathode modules and multiple anode modules are arranged alternately. There are two fastening components, with each cathode module engaging with one of the two fastening components, and each anode module engaging with the other. By having multiple anode modules engage with one fastening component and multiple cathode modules engage with the other fastening component, positive current can be input from one fastening component and negative current from the other, thus achieving the ionization and sterilization function of the anode and cathode modules.

[0018] In one embodiment, the electrolysis module includes multiple electrolytic plates arranged sequentially along the height of the support base, with a distance of 0.3-5 mm between adjacent electrolytic plates. By maintaining a distance of 0.3-5 mm between the cathode and anode plates in the electrolytic plates, the internal resistance between the two electrodes can be reduced, achieving a balance between electrolysis efficiency and energy efficiency.

[0019] In one embodiment, a conductive ring is further included, which is disposed on the electrolysis module and is used to cooperate with the fastening assembly. The conductive ring, made of titanium-based material, supports the electrolysis module and provides both structural support and electrochemical corrosion protection, reducing the risks of corrosion and poor conductivity caused by localized potential differences.

[0020] In one embodiment, the first port is for water inlet and the second port is for water outlet. The housing assembly has a first water flow channel and a second water flow channel. The first port, the first water flow channel, and the disinfection chamber are sequentially connected, as are the second port, the second water flow channel, and the disinfection chamber. The assembly also includes a piston assembly disposed on the housing assembly and located within the first water flow channel. The piston assembly is used to block or open the water path between the first port and the disinfection chamber. When the disinfection filter structure is installed entirely in the water purifier's main unit, the piston is pushed to open the water path between the first port and the disinfection chamber, achieving the water disinfection function. When the disinfection filter structure is removed from the water purifier's main unit, the piston assembly automatically blocks the water path between the first port and the disinfection chamber, preventing liquid leakage from the disinfection chamber.

[0021] In one embodiment, the piston assembly is disposed on the housing assembly and located in the second water flow channel. The piston assembly is used to block or open the water passage between the second inlet and the disinfection chamber. The piston assembly can block or open the water passage between the second inlet and the disinfection chamber, thereby enabling water disinfection or preventing liquid leakage from the disinfection chamber.

[0022] In one embodiment, the piston assembly includes a piston body and an elastic element. The piston body is disposed on the housing assembly and located in the first water flow channel and / or the second water flow channel. The two ends of the elastic element abut against the housing assembly and the piston body, respectively. The elastic element allows the piston assembly to automatically return to its initial position when the entire disinfection filter structure is removed from the water purifier, sealing the water path and preventing liquid leakage from the disinfection chamber, thus achieving a high degree of automation.

[0023] In one embodiment, there are two piston assemblies. One of the two piston assemblies is disposed on the housing assembly and located in the first water flow channel, and the other of the two piston assemblies is disposed on the housing assembly and located in the second water flow channel. With one piston assembly in each of the first and second water flow channels, the water path can be blocked or opened, achieving either water disinfection or leak-proof functions.

[0024] In one embodiment, a first opening is further included, which communicates with both the first water flow channel and the disinfection chamber. The first opening, located on the side of the first water flow channel, allows water to flow from the first opening into the disinfection chamber when the disinfection filter structure is installed in the water purifier unit, thus achieving the water disinfection function. When the disinfection filter structure is removed from the water purifier unit, the piston assembly automatically resets under the action of the elastic element. At this time, the piston assembly is positioned horizontally below the lowest point of the first opening, effectively sealing the water path and preventing liquid leakage from the disinfection chamber.

[0025] In one embodiment, a second opening is further included, which communicates with both the second water flow channel and the disinfection chamber. The second opening allows liquid to enter the disinfection chamber through it, thus enabling electrolytic disinfection.

[0026] In one embodiment, the housing assembly includes a housing member, a sealing cap, and a handle structure. The housing member has the assembly space, a first opening, and a second opening. The sealing cap and the handle structure are both disposed on the housing member, and the sealing cap and the housing member enclose the disinfection chamber. The handle structure facilitates the user's extraction of the entire disinfection filter structure.

[0027] In one embodiment, a filter cartridge holder is also included, which is disposed on the housing assembly and located on the outside of the housing assembly. The filter cartridge holder is used to mate with external components. The filter cartridge holder facilitates the integration of the disinfection filter structure with other components of the water purifier.

[0028] A water purifier includes: a water purification main unit; and the aforementioned disinfection filter structure, wherein the disinfection filter structure is disposed on the water purification main unit.

[0029] The second aspect of this application discloses a water purifier that supports the complete replacement of the disinfection filter structure through a modular design, reducing assembly and disassembly time by 60%. By using a fastening component that penetrates the assembly space and extends to the disinfection chamber to cooperate with the disinfection component, a stable fit is achieved, resulting in better stability and reliability of the disinfection component. The stable assembly of the disinfection filter structure enables reliable water disinfection. Attached Figure Description

[0061] The first aspect of this application discloses a disinfection filter structure. A disinfection component 2 is disposed within a disinfection chamber 101. The disinfection component 2 disinfects the liquid flowing through the disinfection chamber 101. The disinfection component 2 can be a physical disinfection method such as electrolysis, or a chemical disinfection method. A first inlet 103 and a second inlet 104, respectively, communicate with the disinfection chamber 101 to ensure smooth water flow. A fastening component 3 penetrates the assembly space 102 and extends into the disinfection chamber 101 to cooperate with the disinfection component 2, forming a rigid connection between the disinfection component 2 and the housing component 1. This effectively restricts the degree of freedom of the disinfection component 2 and prevents relative displacement between the disinfection component 2 and the housing component 1. This design avoids loosening problems caused by vibration or pressure changes, improving the overall structural reliability. Furthermore, the assembly space 102 restricts the degree of freedom of the fastening component 3, resulting in a good fixing effect of the fastening component 3 on the disinfection component 2.

[0062] In addition to the features of the above embodiments, this embodiment further specifies that both the fastening component 3 and the disinfection component 2 are conductive. Power is directly supplied to the disinfection component 2 via the conductive fastening component 3, eliminating the need for additional wire connections, reducing the complexity of internal wiring, and improving structural compactness. This design allows the fastening component 3 to integrate conductive and fastening functions into one unit, resulting in a more ingenious design and improved utilization efficiency.

[0063] like Figure 2 , Figure 5 and Figure 8-12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of fastening components 3 is multiple, all of which are disposed on the housing assembly 1 and located at the assembly space 102, and all of the multiple fastening components 3 are used for connecting the disinfection component 2 and the housing assembly 1. By providing multiple fastening components 3, the disinfection component 2 and the housing assembly 1 have multiple connections, significantly improving the connection strength between the disinfection component 2 and the housing assembly 1. This design can avoid loosening problems caused by vibration or pressure changes, and improve the reliability of the overall structure.

[0064] In addition to the features of the above embodiments, this embodiment further specifies that the fastening component 3 is made of titanium-based material. By replacing traditional metal materials with titanium-based materials, the corrosion of the fastening component 3 by water can be effectively avoided or reduced, thereby extending the service life of the equipment. The chloride ion corrosion resistance of titanium-based materials is more than three times that of traditional stainless steel.

[0065] In addition to the features of the above embodiments, this embodiment further specifies that the disinfection component 2 is made of titanium-based material. The disinfection component 2 can be made of titanium-based material, for example, the electrodes of the disinfection component 2, with a Ti-based Pt noble metal oxide anode coated on the surface, achieving a balance between corrosion resistance and cost controllability of the filter element device in chlorine-containing wastewater environments.

[0066] like Figure 5 and Figure 18 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fastening component 3 includes a conductive rod 31 and a mating part 32.

By providing the sealing element 4, the disinfection component 2 generates a continuous pre-tightening force when squeezed by the mating part 32, so that the conductive rod 31, the sealing element 4, and the housing assembly 1 form a dynamic seal, which can prevent water in the disinfection chamber 101 from leaking from the assembly space 102, and the sealing pressure fluctuation range is less than or equal to 15%. This design allows the sealing element 4 and the mating part 32 to work together to compensate for gaps caused by thermal expansion and contraction and vibration. Preferably, the sealing element 4 is made of silicone material.

The connecting rod head 312 being located in the adapter groove 109 makes the fixation of the disinfection assembly 2 by the fastening assembly 3 more stable and reliable. Furthermore, the connecting rod head 312 can engage with the water purifier's main unit using a conical surface, and in conjunction with the spring device on the main unit, the spring device carries stress, ensuring the stability of the disinfection assembly 2 after the main unit is powered on.

The number of fastening components 3 is two, and each of the multiple cathode modules 221 cooperates with one of the two fastening components 3, and each of the multiple anode modules 222 cooperates with the other of the two fastening components 3. By having multiple anode modules 222 cooperate with one of the fastening components 3 and multiple cathode modules 221 cooperate with the other fastening component 3, positive electricity can be input from one fastening component 3 and negative electricity can be input from the other fastening component 3, thereby realizing the ionization and disinfection function of the anode modules 222 and cathode modules 221.

The piston assembly can block or open the water passage between the second opening 104 and the disinfection chamber 101, thereby realizing the function of water disinfection or preventing liquid leakage in the disinfection chamber 101.

[0078] like Figure 6-7 and Figure 20 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the piston assembly includes a piston body 6 and an elastic element. The piston body 6 is disposed on the housing assembly 1 and located in the first water flow channel 105 and / or the second water flow channel 106.

With one piston assembly in each of the first water flow channel 105 and the second water flow channel 106, the water path can be blocked or opened, realizing the water supply disinfection function or the sealing and leak-proof function.

[0080] like Figure 2-4 and Figure 6-7 As shown, in addition to the features of the above embodiments, this embodiment further includes a first opening 107, which is connected to both the first water flow channel 105 and the disinfection chamber 101. The first opening 107 is located on the side of the first water flow channel 105. When the disinfection filter structure is installed in the water purifier, the piston is pushed, allowing water to flow from the first opening 107 into the disinfection chamber 101, thus achieving the water disinfection function.
