Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a filter module and a water purifier having the same. Background Technology

[0002] In drinking water purification and industrial water treatment, filter modules are core components, and their performance directly affects the quality of the effluent and the stability of the system. A typical filter module usually consists of a filter bottle and a replaceable filter cartridge installed inside. Currently, the widely used filter modules have a relatively straightforward water flow path design: raw water typically enters the filter cartridge directly through the inlet, and after flowing through the filter media inside, purified water flows out from the center of the cartridge. These filter modules are susceptible to media migration and leakage. The granular or fibrous filter media filling the cartridge is easily loosened and broken under the impact of water flow, and may migrate with the water. This may then flow out through the pure water outlet along with the purified water, contaminating the water quality. Utility Model Content

[0003] The purpose of this invention is to provide a filter module that ensures the filter medium does not flow out with the purified water, thus guaranteeing water quality safety.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a filter module, comprising a filter bottle and a filter element located inside the filter bottle, wherein the filter bottle is provided with an inlet, a pure water outlet and a concentrated water outlet, a water guiding channel communicating with the inlet is provided between the filter bottle and the filter element, a pure water channel is provided between the filter element and the pure water outlet, a filter medium is provided in the water guiding channel and / or the pure water channel, a carbon rod is provided inside the filter element, and a screen is provided inside the pure water outlet, the screen allowing pure water to pass through and preventing the filter medium from leaving the pure water channel.

[0005] By adopting the above technical solution, the maximum diameter of the filter element is smaller than the diameter of the filter bottle, forming a gap between the filter element and the filter bottle, thereby forming a water guiding channel. The size of the water guiding channel is configured to allow the filter medium to be placed in, and the raw water entering from the inlet can pass through the filter medium normally. The filter element is a circular cylindrical structure with a central opening. The carbon rod is placed in the central opening of the filter element. The mesh is a circular mesh structure with several fine holes distributed on the mesh. The pore size of the fine holes is smaller than the diameter of the filter medium. The diameter of the mesh is at least the same as the inner diameter of the pure water outlet. By setting the mesh, the filter medium will not migrate with the water flow and will not flow out with the purified pure water, ensuring water quality safety. In addition, by setting a water guiding channel between the filter bottle and the filter element and placing the filter medium inside to form radial filtration, and by setting an axially extending carbon rod and filter medium inside the filter element, high-efficiency filtration of pure water is achieved.

[0006] A further feature of this invention is that the filter medium is strontium ore particles.

[0007] By adopting the above technical solution, strontium ore, as a natural mineral filter medium, has the function of adsorbing heavy metal ions, thereby improving the adsorption effect on heavy metal lead.

[0008] A further feature of this invention is that the water guiding channel is circumferentially arranged outside the side wall of the filter element.

[0009] By adopting the above technical solution, water guiding channels are set around the side wall of the entire filter element, which increases the filtration area of ​​raw water and enhances the filtration efficiency.

[0010] A further feature of this invention is that: a hollow central tube is provided inside the filter element, the carbon rod is disposed inside the central tube, a first water-permeable hole is provided through the side wall of the central tube, and the water guiding channel is in fluid communication with the carbon rod through the first water-permeable hole.

[0011] By adopting the above technical solution, the central tube extends along the central axis of the filter element, and there is a gap between the carbon rod and the central tube. The gap space between the central tube and the carbon rod forms a pure water channel. Several first water permeable holes are arranged through the side wall of the entire central tube. The water filtered by the filter medium in the water guide channel enters the pure water channel through the first water permeable holes, forming radial filtration along the filter element axis. Then, it is discharged through the pure water outlet connected to the pure water channel, forming axial drainage along the filter element. The two water flow paths are combined to achieve high-efficiency pure water filtration.

[0012] A further feature of this invention is that the carbon rod is configured as a hollow structure, and a second water-permeable hole is provided through the side wall of the carbon rod, and the pure water channel is in fluid communication with the first water-permeable hole through the second water-permeable hole.

[0013] By adopting the above technical solution, the central tube extends along the central axis of the filter element, the carbon rod is set inside the central tube, and the pure water channel is the hollow area inside the carbon rod. The water filtered by the filter medium in the water guide channel enters the pure water channel inside the carbon rod through the first water permeable hole and the second water permeable hole in sequence, and then is discharged through the pure water outlet connected to the pure water channel. This forms a water flow path of radial filtration and axial drainage, achieving efficient pure water filtration, and also increases the contact area between water and carbon rod, making the filtration effect better.

[0014] A further feature of this invention is that the first water-permeable hole and the second water-permeable hole are staggered.

[0015] By adopting the above technical solution, the gap between the filter element and the carbon rod is set to form a gap space. After the water filtered by the filter medium in the water guide channel passes through the first water permeable hole, the water stays in the gap space for a longer time due to the staggered distribution of the first and second water permeable holes, thus extending the filtration reaction time between the water and the carbon rod and improving the filtration effect.

[0016] A further feature of this invention is that a water-passing connector is provided in the pure water channel, the water-passing connector is connected to the pure water outlet water path, and the end of the water-passing connector near the filter element is connected to the carbon rod.

[0017] By adopting the above technical solution, the outer wall of the water-passing connector is sealed to the central pipe, and the inner wall of the water-passing connector is sealed to the carbon rod, preventing water leakage from the pure water channel and thus preventing waste of pure water. This ensures that all water in the pure water channel can flow to the pure water outlet, guaranteeing filtration efficiency.

[0018] A further feature of this invention is that: a sealing rib is provided in the middle of the water-passing connector, and a water outlet pipe is provided below the pure water outlet. The water outlet pipe and the water-passing connector are sealed and connected by the sealing rib. The water-passing connector is connected to the pure water outlet through the water outlet pipe. A drain pipe is provided circumferentially on the outside of the water outlet pipe. The bottom of the drain pipe abuts against the filter element. The water outlet pipe, the drain pipe, and the filter element together form a flow path that restricts the water flow in the filter element to the concentrated water outlet.

[0019] By adopting the above technical solution, the maximum diameter of the sealing rib is larger than the inner diameter of the filter element, so that the water-passing connector located below the sealing rib is sealed and inserted into the central opening of the filter element and sealed and connected to the central tube. The water-passing connector located above the sealing rib is sealed and inserted into the outlet pipe. The drain pipe is placed on the top of the filter element and the maximum diameter of the drain pipe is larger than the outer diameter of the filter element, so that the filter element is covered inside the drain pipe. The drain pipe protrudes circumferentially along the central axis of the filter bottle and upwards to form a barrier. A gap is set between the barrier and the outlet pipe. This gap space is the drainage space, which is in fluid communication with the concentrate outlet. The concentrate in the filter element moves into the drainage space due to the obstruction of the drain pipe and is discharged through the concentrate outlet, which is the only outlet connected to the drainage space. The part below the sealing rib is used for filtration, the part above the sealing rib is used for pure water discharge, and the part outside the outlet pipe is used for concentrate discharge. The layout is reasonable, so that different functions are performed in different areas, which is convenient for mass production and later maintenance.

[0020] A further feature of this invention is that the side wall of the water-passing connector is provided with a stepped surface in the circumferential direction, and the inner wall of the central pipe and the water outlet pipe are both provided with limiting ribs corresponding to the stepped surface.

[0021] By adopting the above technical solution, the limiting rib seal is inserted into the stepped surface of the water-passing connector, which prevents the water-passing connector from easily loosening under the impact of water flow, thus reducing the sealing performance. This not only increases the tightness between the water-passing connector and the central pipe, but also enhances the sealing effect.

[0022] Another objective of this utility model is to provide a water purifier, comprising a filter module, a housing, a heating tank, a control panel, a booster pump, a control water circuit board, and a filter water circuit board. The filter module, the heating tank, the booster pump, the control water circuit board, and the filter water circuit board are disposed inside the housing, and the control panel is at least partially exposed outside the housing.

[0023] By adopting the above technical solution, the water purifier is equipped with a filter module to ensure that the filter medium does not flow out with the purified water, thus ensuring water quality safety.

[0024] In summary, this utility model has the following beneficial effects: by setting a water guiding channel between the filter bottle and the filter element and building a filter medium inside to form radial filtration, and by setting a carbon rod and a filter medium inside the filter element to achieve efficient filtration of pure water; by setting a partition in the pure water outlet, the filter medium will not migrate with the water flow and flow out with the purified pure water under the impact of water flow, thus ensuring water quality safety.

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] Example 1:

[0034] A filter module, such as Figure 1-3As shown, the filter includes a filter bottle 1 and a filter element 2 located inside the filter bottle 1. The filter bottle 1 has an inlet 11, a pure water outlet 12, and a concentrated water outlet 13. A water guiding channel 31 communicating with the inlet 11 is provided between the filter bottle 1 and the filter element 2. A pure water channel 32 is provided between the filter element 2 and the pure water outlet 12. Filter media is provided in the water guiding channel 31 and / or the pure water channel 32. A carbon rod 4 is provided inside the filter element 2. A screen 5 is provided inside the pure water outlet 12. The screen 5 allows pure water to pass through and prevents the filter media from leaving the pure water channel 32. The maximum diameter of filter element 2 is smaller than the diameter of filter bottle 1, forming a gap between filter element 2 and filter bottle 1, thus forming a water guiding channel 31. Filter media can be installed inside either the water guiding channel 31 or the pure water channel 32, or both can contain filter media. The filter media can be the same or different, depending on the requirements. The size of the water guiding channel 31 is configured to accommodate the filter media, and the raw water entering from the inlet 11 can pass through the filter media normally. Filter element 2 is a cylindrical annular structure with a central opening. Carbon rod 4 is placed inside the central opening of filter element 2. The mesh 5 is a circular mesh structure, connected to the pure water outlet 12 via a pipe. The screen 5 is installed inside the pure water outlet 12 by hot-melt welding. After installation, the screen 5 is integrally formed with the pure water outlet 12. The above installation method is only a preferred embodiment. However, the screen 5 of this application is not limited to the above installation method. The screen 5 has a number of fine holes distributed on it. The diameter of the fine holes is smaller than the diameter of the filter medium. The diameter of the screen 5 is at least the same as the inner diameter of the pure water outlet 12. By setting the screen 5 inside the pure water outlet 12, the filter medium will not migrate with the water flow and will not flow out with the purified pure water, thus ensuring water quality safety. In addition, by setting a water guiding channel 31 between the filter bottle 1 and the filter element 2 and building a filter medium inside to form radial filtration, and by setting an axially extending carbon rod 4 and a filter medium inside the filter element 2, high-efficiency filtration of pure water is achieved.

[0035] Preferably, the filter medium is strontium ore particles. As a natural mineral filter medium, strontium ore has the function of adsorbing heavy metal ions, thereby improving the adsorption effect on heavy metal lead.

[0036] Preferably, the water guiding channel 31 is circumferentially arranged on the outside of the side wall of the filter element 2. The water guiding channel 31 is arranged around the entire side wall of the filter element 2, increasing the filtration area of ​​the raw water and enhancing the filtration efficiency.

[0037] Preferably, the filter element 2 has a hollow central tube 6, and the carbon rod 4 is disposed inside the central tube 6. A first water-permeable hole 61 is provided through the side wall of the central tube 6, and the water guiding channel 31 is in fluid communication with the carbon rod 4 through the first water-permeable hole 61. The central tube 6 extends along the central axis of the filter element 2, and there is a gap between the carbon rod 4 and the central tube 6. The gap space between the central tube 6 and the carbon rod 4 forms a pure water channel 32. A plurality of first water-permeable holes 61 are provided through the side wall of the entire central tube 6. The water filtered by the filter medium in the water guiding channel 31 enters the pure water channel 32 through the first water-permeable holes 61, forming radial filtration along the axis of the filter element 2, and then is discharged through the pure water outlet 12 connected to the pure water channel 32, forming axial drainage along the filter element 2. The two water flow paths are combined to achieve efficient pure water filtration.

[0038] Preferably, the carbon rod 4 is configured as a hollow structure, and a second water-permeable hole 41 is provided through the side wall of the carbon rod 4. The pure water channel 32 is in fluid communication with the first water-permeable hole 61 through the second water-permeable hole 41. The central tube 6 extends along the central axis of the filter element 2, and the carbon rod 4 is disposed inside the central tube 6. The pure water channel 32 is the hollow area inside the carbon rod 4. The water filtered by the filter medium in the water guide channel 31 enters the pure water channel 32 (the interior of the hollow carbon rod 4) inside the carbon rod 4 through the first water-permeable hole 61 and the second water-permeable hole 41 in sequence, and then is discharged through the pure water outlet 12 connected to the pure water channel 32. This increases the contact area between the water and the carbon rod 4, making the filtration effect better.

[0039] Preferably, the first water-permeable hole 61 and the second water-permeable hole 41 are staggered. The gap between the filter element 2 and the carbon rod 4 forms a gap space. After the water filtered by the filter medium in the water guide channel 31 passes through the first water-permeable hole 61, the staggered distribution of the first water-permeable hole 61 and the second water-permeable hole 41 increases the retention time of the water in the gap space, prolongs the filtration reaction time between the water and the carbon rod 4, and makes the filtration effect better.

[0040] Preferably, a water-passing connector 7 is provided inside the pure water channel 32. The water-passing connector 7 is connected to the pure water outlet 12, and the end of the water-passing connector 7 near the filter element 2 is connected to the carbon rod 4. The outer wall of the water-passing connector 7 is sealed to the central tube 6, and the inner wall of the water-passing connector 7 is sealed to the carbon rod 4 to prevent water leakage from the pure water channel 32, thus preventing waste of pure water and ensuring that all water in the pure water channel 32 flows to the pure water outlet 12, thereby guaranteeing filtration efficiency.

[0041] Preferably, the water-passing connector 7 has a sealing rib 71 in the middle, and a water outlet pipe 82 is provided below the pure water outlet 12. The water outlet pipe 82 and the water-passing connector 7 are sealed and connected by the sealing rib 71. The water-passing connector 7 is connected to the pure water outlet 12 through the water outlet pipe 82. A drain pipe 83 is provided circumferentially on the outside of the water outlet pipe 82. The bottom of the drain pipe 83 abuts against the filter element 2. The water outlet pipe 82, the drain pipe 83, and the filter element 2 together form a flow path that restricts the water flow in the filter element 2 to the concentrated water outlet 13. The maximum diameter of the sealing rib 71 is larger than the inner diameter of the filter element 2, so that the water-passing connector 7 located below the sealing rib 71 is sealed and inserted into the central opening of the filter element 2 and sealed and connected to the central pipe 6. The water-passing connector 7 located above the sealing rib 71 is sealed and inserted into the outlet pipe 82. The drain pipe 83 is placed on top of the filter element 2, and the maximum diameter of the drain pipe 83 is larger than the outer diameter of the filter element 2, so that the filter element 2 is covered inside the drain pipe 83. The drain pipe 83 protrudes circumferentially along the central axis of the filter bottle 1 and protrudes upward to form a barrier 831. The filter element 2 is separated from the outlet pipe 82 by a gap, which is a drainage space 832. It is fluidly connected to the concentrate outlet 13. The concentrate in the filter element 2 moves into the drainage space 832 due to the obstruction of the drain pipe 83, and is discharged through the concentrate outlet 13, which is the only outlet connected to the drainage space 832. The outlet 13 is located below the sealing rib 71 for filtration, above the sealing rib 71 for pure water discharge, and outside the outlet pipe 82 for concentrate discharge. The layout is reasonable, so that different functions are performed in different areas, which is convenient for mass production and later maintenance.

[0042] The basic working principle of this utility model is as follows: the raw water entering from the inlet 11 first passes through the water guide channel 31 along the side wall of the filter bottle 1, and is fully integrated with the strontium ore particles in the water guide channel 31 for coarse filtration. The coarsely filtered water passes through the filter element 2 radially through the first water permeable hole 61 into the central tube 6, and through the second water permeable hole 41 into the pure water channel 32 in the carbon rod 4. It contacts and filters with the carbon rod 4 in the pure water channel 32. The filtered pure water is discharged through the water flow connector 7 and the pure water outlet 12 connected to the pure water channel 32. The concentrated water in the filter element 2 moves to the drainage space 832 due to the obstruction of the drain pipe 83, and is discharged through the concentrated water outlet 13, the only outlet connected to the drainage space 832, forming a radial filtration and axial drainage water flow path to achieve high-efficiency pure water filtration.

[0043] Example 2:

[0044] A filter module, such as Figure 4As shown, the difference between this embodiment and specific embodiment one is that: the side wall of the water-passing connector 7 is provided with a stepped surface 72 circumferentially, and the inner wall of the central pipe 6 and the outlet pipe 82 are both provided with limiting ribs 62 corresponding to the stepped surface 72. The limiting ribs 62 are sealed and inserted into the stepped surface 72 of the water-passing connector 7, preventing the water-passing connector 7 from easily loosening under the impact of water flow, which would lead to a decrease in sealing performance. This increases the tightness between the water-passing connector 7 and the central pipe 6 and enhances the sealing effect.

[0045] Example 3:

[0046] Based on the same inventive concept, this utility model embodiment provides a water purifier / water heater having the filter module described above, such as... Figure 5-6 As shown, the device also includes a housing 91, a heating tank 92, a control panel 93, a booster pump 94, a water circuit control panel 95, and a filter element water circuit panel 96. The filter element module, the heating tank 92, the booster pump 94, the control panel 95, and the filter element water circuit panel 96 are disposed inside the housing 91, while the control panel 93 is at least partially exposed outside the housing 91. The filter element module within the water purifier ensures that the filter medium does not flow out with the purified water, guaranteeing water quality safety. The filter element water circuit board 96 is connected to the filter element module's inlet 11, pure water outlet 12, and concentrated water outlet 13, forming an inlet end 961, a pure water outlet 962, and a concentrated water outlet 963, respectively. The control water circuit board 95 has a raw water inlet channel 951, on which an inlet solenoid valve 952 is installed. The raw water inlet channel 951 is connected to the filter element water circuit board 96's inlet end 961 via the inlet solenoid valve 952 and a booster pump 94. The filter element water circuit board 96 has a pure water inlet channel 964, which is connected to the filter element water circuit board 96's pure water outlet 962. The other end branches into two paths; one path is equipped with a water replenishment solenoid valve 965, which is connected to the water replenishment outlet 962 via the water replenishment solenoid valve 962. A solenoid valve 965 is connected to a heating tank 92 for heating and storing pure water. Another path is provided with a drain solenoid valve 966, which is connected to the outside of the water purifier for outputting room temperature pure water. The filter element water circuit board 96 is provided with a concentrated water channel 967. One end of the concentrated water channel 967 is provided with a flushing solenoid valve 968, which is connected to the outside of the water purifier for discharging concentrated water. The control water circuit board 95 and the filter element water circuit board 96 are set independently, preferably vertically spaced. The pipe connection between the control water circuit board 95 and the filter element water circuit board 96 is beneficial for the internal space arrangement and reduces the difficulty of adjusting the position of the pipe components on the water circuit board.
