Description

Technical Field

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

[0002] Central water purifiers, as an important water treatment device, are widely used in households, businesses, and industries to remove impurities and improve water quality. As people's pursuit of health and quality of life continues to improve, the demand for central water purifiers has increased year by year. In existing technologies, the core function of central water purifiers is to purify water through multi-stage filtration. Their design and structure directly affect filtration efficiency and user experience. Traditional central water purifiers typically use a single or simple multi-layer filtration structure, combined with filter elements of different materials, to remove harmful substances from the water, thereby meeting users' demand for clean water.

[0003] In existing technologies, efficient water purification is typically achieved through the following conventional methods: First, multiple layers of filter screens are installed within a single cylinder, utilizing the gaps between the screens to achieve step-by-step filtration; second, multiple independent filter modules are installed within the cylinder, each responsible for a specific type of filtration; and third, a piping system is introduced to direct untreated water to different filtration areas before it is collected and discharged through an outlet. While these methods can achieve water purification to a certain extent, their design and structure have certain limitations.

[0004] In actual use, existing central water purifiers face the challenge of balancing filtration effectiveness and filtration speed. For example, in physical filtration, the filter element achieves filtration through pores that allow water to pass through but block impurities. Large pore sizes result in poor filtration, while smaller pores result in slower filtration speeds, preventing rapid production of large quantities of purified water. Furthermore, impurities in unpurified water in traditional water purifiers easily adhere to the inner walls of the purifier, forming scale that requires frequent cleaning and creates a poor user experience. Summary of the Invention

[0005] In order to solve the problem that traditional water purifiers have slow filtration speed and are prone to scale generation, the present application provides a central water purifier.

[0006] The central water purifier provided in this application adopts the following technical solution:

[0007] A central water purifier, comprising:

[0008] The cylinder is provided with a water inlet and a water outlet;

[0009] A filter element is disposed in the cylinder, the filter element comprising a box body and a plurality of filter plates, the plurality of filter plates being arranged at intervals and dividing the interior of the box body into a plurality of water filtering layers;

[0010] a first pipe, which penetrates the box body and passes through the plurality of filter plates, and connects the plurality of water filtration layers with the water inlet;

[0011] The second pipe penetrates into the box body and passes through the plurality of filter plates. The second pipe is communicated with the water outlet. The second pipe is used for filtering the water in the water filter layer and then entering the interior of the second pipe.

[0012] By adopting the above technical solutions, the central water purifier can achieve rapid filtration of water flow. Specifically:

[0013] The cylinder, the main structure, coordinates with the water inlet and outlet to introduce and discharge water. Multiple filter plates within the filter element divide the interior of the cartridge into multiple filtration layers. The first pipe runs through these plates and connects the filtration layers to the water inlet, diverting the flow of raw water, allowing it to be filtered in different filtration layers and increasing filtration speed. The second pipe collects the filtered water and directs it to the outlet, effectively preventing the mixing of unfiltered and filtered water and ensuring the purity of the outlet water.

[0014] Impurities in the raw water are retained inside the box, preventing the impurities from adhering to the inner wall of the cylinder to form scale.

[0015] The water in adjacent filtration layers can share the same filter plate for filtration, saving costs.

[0016] Optionally, the central water purifier further includes a third pipeline and a first valve;

[0017] The bottom of the cylinder is provided with a first drain hole, and the first drain hole is provided with the first valve.

[0018] The third pipe penetrates into the plurality of water filtering layers and is used to connect the plurality of water filtering layers with the first sewage discharge hole.

[0019] By adopting the above technical solution, the central water purifier is equipped with a third pipe and a first valve. The third pipe connects the multiple filter layers to the first drain hole at the bottom of the cylinder. This design allows the first valve to be opened when drainage is needed, allowing impurities or sewage in the filter layers to be discharged through the first drain hole, thus cleaning the filter element.

[0020] Optionally, the cylinder comprises a cylinder cover and a cylinder body that are threadedly connected;

[0021] The water inlet and the water outlet are both provided on the cylinder cover, and the first drain hole is provided on the bottom of the cylinder body;

[0022] The first pipe is detachably connected to the cylinder cover;

[0023] A connecting portion is provided on the inner bottom wall of the cylinder body, and one end of the third pipe is threadedly connected to the connecting portion.

[0024] By adopting the above technical solution, the cylinder of the central water purifier consists of a cylinder cover and a cylinder body connected by threads. This structural design facilitates the assembly and disassembly of the equipment, improving the convenience of maintenance and cleaning. The water inlet and outlet are set on the cylinder cover, and the first sewage hole is set at the bottom of the cylinder body, realizing the rational planning of the water flow path and facilitating the smooth discharge of sewage. The first pipe is detachably connected to the cylinder cover, and the connection part on the inner bottom wall of the cylinder body is threadedly connected to one end of the third pipe. This not only enhances the stability of the structure, but also makes it easier to disassemble the filter element, the first pipe, and the third pipe, facilitating the replacement of components.

[0025] Optionally, the portion where the second pipe passes through the filter plate is provided with a first water hole communicating with the interior thereof;

[0026] The second pipe has a filter section, the filter section penetrates into the box body, and the filter section does not pass through the filter plate;

[0027] By adopting the above technical solution, the filter section of the second pipe penetrates the box body and can filter the water in the water filter layer, improving the water purification effect. The first water hole is set at the part where the second pipe passes through the filter plate, so that the water in the water filter layer can penetrate the filter plate and enter the second pipe through the first water hole. Through the above arrangement, the water in the water filter layer can enter the second pipe through different paths, improving the water purification efficiency.

[0028] Optionally, the second pipe has a filter section, and the filter section penetrates into the box body and passes through the filter plate.

[0029] By adopting the above technical solution, the water in the water filtration layer needs to be purified by the filter plate and the filter section in sequence before entering the second pipe, thereby improving the water purification effect.

[0030] Optionally, the box body is a watertight box body, one end of the second pipe passes through the box body and is connected to the water outlet, and the water in the water filter layer enters the second pipe and is discharged through the water outlet without contacting the inner wall of the cylinder.

[0031] By adopting this technical solution, the central water purifier's housing is designed to be impermeable. After purification, the water in the filter layer does not come into contact with the inner wall of the housing, reducing the cleanliness requirements for the inner wall. Furthermore, one end of the second pipe extends beyond the housing and connects to the outlet, directly channeling the purified water from the filter layer. This simplifies the water flow path, reduces water resistance, and improves water purification efficiency.

[0032] Optionally, the box body is a water-impermeable box body; or, the side walls of at least one layer of the water filtering layer sequentially present from top to bottom are filter walls that can be used for filtering;

[0033] One end of the second pipe passes through the box body, and a second water hole is provided at the passing portion, and the second water hole is used to allow water in the second pipe to be discharged to the bottom of the cylinder;

[0034] The central water purifier further includes a fourth pipe, one end of which is in communication with the inner bottom of the cylinder, and the other end of which is in communication with the water outlet.

[0035] By adopting the above technical solution, a second water hole is provided at the exit of the second pipe, allowing filtered water in the filtration layer to be discharged from the second water hole to the bottom of the cylinder, thereby storing clean water and ensuring that a large amount of clean water is immediately available when needed. The fourth pipe is provided to collect water from the bottom of the cylinder and guide it to the outlet, ensuring that the stored clean water can be smoothly discharged from the outlet.

[0036] Optionally, the second water hole is located above the filter element.

[0037] By adopting the above technical solution, the second water hole is arranged above the filter element, so that the stored clean water is not easy to flow back into the second pipe or even the water filter layer through the second water hole.

[0038] Optionally, the central water purifier further includes a second valve;

[0039] The bottom of the cylinder is provided with a second drain hole, and the second valve is provided at the second drain hole.

[0040] By adopting the above technical solution, the central water purifier is equipped with a second drain hole at the bottom of the cylinder, and a second valve is installed at this second drain hole. This design provides the central water purifier with a more comprehensive drainage function, effectively removing impurities and dirt accumulated at the bottom of the cylinder, preventing blockage and contamination. For example, by opening the second valve, unused purified water stored in the cylinder can be discharged, preventing it from deteriorating due to long-term non-use.

[0041] Optionally, the central water purifier further includes a third valve;

[0042] The first end of the second pipe passes through the cylinder, the third valve is arranged at the first end of the second pipe, and the first end of the second pipe is used for introducing a cleaning medium.

[0043] By adopting the above technical solution, the central water purifier is equipped with a third valve, located at the first end of the second pipe, which is capable of introducing a cleaning medium. This design enables reverse flushing of the filter element and cleaning of the inner wall of the cylinder, effectively removing impurities accumulated inside the filter element and the cylinder, and enhancing the self-cleaning ability of the water purifier.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0047] 3. By introducing the cleaning medium into the first end of the second pipe, the filter element and the inner wall of the cylinder can be cleaned at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The following is combined with Figures 1 to 5 This application is described in further detail.

[0061] like Figures 1 to 3 As shown, an embodiment of the present application discloses a central water purifier, including a cylinder 1, a filter element 2, a first pipe 3, a second pipe 4, a third pipe 5 and a first valve 51.

[0062] Specifically, the cylinder body 1 includes a cylinder cover 11 and a cylinder body 12 that are threadedly connected. The cylinder cover 11 is provided with a water inlet 111 and a water outlet 112. The bottom of the cylinder body 12 is provided with a first drain hole 121.

[0063] The filter element 2 is disposed within the cylinder 1 and includes a housing 21 and a plurality of filter plates 22. The housing 21 may be cylindrical. The filter plates 22 are evenly spaced vertically within the housing 21, dividing the interior of the housing 21 into a plurality of filter layers 23.

[0064] One end of the first pipe 3 is connected to the water inlet 111, and the other end penetrates the box body 21 and passes through the multiple filter plates 22. The first pipe 3 is provided with first through-holes 31. Each filter layer 23 is connected to the first pipe 3 through at least one first through-hole 31, allowing unpurified raw water entering the first pipe 3 through the water inlet 111 to flow into each filter layer 23.

[0065] The second pipe 4 is connected to the water outlet 112. One end of the second pipe 4 penetrates the box body 21 and passes through the multiple filter plates 22. The raw water in the water filter layer 23 enters the second pipe 4 after being filtered, so that the filtered clean water can be subsequently led out of the water outlet 112.

[0066] Various filtering methods are possible. For example, the second pipe 4 has a filter section 41 that extends into the housing 21 but does not penetrate the filter plate 22. This allows water in the filter layer to pass directly through the sidewalls of the filter section 41 and into the second pipe 4, while impurities in the water are blocked by the sidewalls of the filter section 41.

[0067] For example, Figures 2 to 5As shown, the portion of the second pipe 4 that passes through the filter plate 22 is provided with a first water hole 421 that communicates with the interior thereof. Water in the filter layer 23 can penetrate the filter plate 22 and enter the second pipe 4 through the first water hole 421. Specifically, the filtration section 41 is assembled from multiple filter units, each comprising a first sub-tube 42 and a second sub-tube 43. The first and second sub-tubes 42 and 43 are integrally formed and coaxially connected. The outer diameter of the first sub-tube 42 is smaller than that of the second sub-tube 43, forming a step at their junction. Threads are provided on the outer wall of the first sub-tube 42 and the inner wall of the second sub-tube 43, allowing the first sub-tube 42 to be threadedly connected to the second sub-tubes 43 of other filter units. The filter plate 22 is provided with a sleeve hole with a diameter larger than the outer diameter of the first sub-tube 42 and smaller than that of the second sub-tube 43. This allows the filter plate 22 to be sleeved onto the first sub-tube 42 and sandwiched between the two second sub-tubes 43, thus achieving structural stability. Sealing rings 6 are provided on opposite sides of the second sub-tube 43 . The sealing rings 6 are sleeved on the first sub-tube 42 . The sealing rings 6 are used to improve the sealing effect and prevent unfiltered water from directly passing through the first through hole 31 .

[0068] For another example, the portion where the second pipe 4 passes through the filter plate 22 is not provided with the first water hole 421, and the filter section 41 of the second pipe 4 passes through the filter plate 22, so that the water in the filter layer 23 needs to be filtered by the filter plate 22 and the filter section 41 respectively before it can enter the second pipe 4, which helps to improve the filtering effect.

[0069] The incoming water in the second pipe 4 can be directly led out to the water outlet 112, or it can be first led into the cylinder 1 for temporary storage and then led out to the water outlet 112 when needed.

[0070] Specifically, in the first case, if Figure 3 As shown, one end of the second pipe 4 passes through the box body 21 and is connected to the water outlet 112. After the water in the water filter layer 23 enters the second pipe 4, it is discharged through the water outlet 112 without contacting the inner wall of the cylinder body 1. This achieves rapid supply of purified water, and the purified water does not contact the inner wall of the cylinder body 1, which reduces the requirements for the cleanliness of the interior of the cylinder body 1. In the first case, the box body 21 is selected to be impermeable.

[0071] In the second case, if Figure 2As shown, one end of the second pipe 4 passes through the box body 21, and a second water hole 44 is provided at the passing portion. The clean water in the second pipe 4 can be discharged to the bottom of the cylinder 1 through the second water hole 44, thereby realizing the storage of clean water. The central water purifier also includes a fourth pipe 7, one end of the fourth pipe 7 is connected to the inner bottom of the cylinder 1, and the other end is connected to the water outlet 112. When the stored clean water is needed, the clean water can flow to the water outlet 112 through the second pipe 4. Among them, the height of the second water hole 44 should not be too low to prevent the stored clean water from flowing back into the second pipe 4 through the second water hole 44. For example, the second water hole 44 can be located above the filter element 2.

[0072] In the second case, the box body 21 can be water-permeable or not. When the box body 21 is a water-permeable box body 21, the side walls of at least one water filter layer 23 are provided from top to bottom as filter walls 231 that can be used for filtering, while the other parts of the box body 21 are still water-impermeable structures. The water in the water filter layer 23 can be filtered through the filter walls 231, thereby improving the water purification efficiency. Among them, the number of water filter layers 23 with filter walls 231 can be determined according to the maximum clean water storage capacity set in the cylinder 1, so that the stored clean water will not flow back into the water filter layer 23 through the filter walls 231, reducing the probability that the stored clean water will pollute the raw water in the water filter layer 23 and the clean water in the second pipe 4 after deterioration, and also avoiding the filter structure such as the filter wall 231 from being immersed in deteriorated clean water for a long time.

[0073] In the above description, the filter structure of the filter plate 22, filter section 41, and filter wall 231 is not strictly limited. For example, the filter structure may include a composite structure composed of filter material and multiple layers of filter ceramic plates, with filter material provided between any adjacent filter ceramic plates. The filter material may be filter cotton, activated carbon, or the like.

[0074] One end of the third pipe 5 penetrates through the plurality of water filter layers 23, and the other end communicates with the first drain hole 121. The first valve 51 is provided at the first drain hole 121. The third pipe 5 is provided with a second through hole 52 communicating with the water filter layer 23.

[0075] During the water purification process, the first valve 51 is in a closed state, and the water in the water filtration layer 23 cannot be discharged through the first sewage hole 121. The impurities filtered out by the raw water in the water filtration layer 23 remain in the water filtration layer 23; when sewage needs to be discharged, the first valve 51 can be opened, and raw water can be introduced into the water filtration layer 23 through the first pipe 3. The raw water can clean the water filtration layer 23, flush the impurities into the third pipe 5 and finally discharge them.

[0076] It should be noted that, by reasonably setting the number of layers of the water filter layer 23 with the filter wall 231, the stored clean water is prevented from flowing back into the water filter layer 23, and the loss of the stored clean water caused by the stored clean water being discharged through the third pipe 5 when the water filter layer 23 is flushed can also be avoided.

[0077] like Figure 2 As shown, in some embodiments, the central water purifier further includes a second valve 45. A second drain hole 122 is provided at the bottom of the cylinder 1, and the second valve 45 is located at the second drain hole 122. Since the purified water stored in the cylinder 1 may deteriorate if not used for a long time, the second valve 45 can be periodically opened to drain the deteriorating purified water, thereby preventing contamination of the interior of the cylinder 1.

[0078] like Figure 2 As shown, in some embodiments, the central water purifier further includes a third valve 46. The first end of the second pipe 4 passes through the cylinder 1, and the third valve 46 is provided at the first end of the second pipe 4. The first end of the second pipe 4 is used to introduce a cleaning medium. The cleaning medium may be clean water (the water pressure may be selected according to actual needs) or compressed air, etc. For example, clean water is introduced into the second pipe 4, and a portion of the clean water can be discharged from the second water hole 44. Since the second water hole 44 is located above the filter element 2, the clean water discharged from the second water hole 44 can clean the outer surface of the filter element 2 and the inner wall of the cylinder 1, and the cleaned waste water can be discharged from the second sewage outlet; the other portion of the clean water can be used to backwash the dirt in the filter wall 231, the filter plate 22 and the filter layer 23, and the cleaned waste water can be discharged from the first sewage outlet.

[0079] After flushing with clean water, the need for compressed air can be determined based on actual needs. For example, if the central water purifier is not needed for filtration or storage of purified water for a long period of time, compressed air can be introduced into the first end of the second pipe 4. In addition to cleaning the filter wall 231 and filter plate 22, the compressed air can also dry the filter element 2 and the interior of the cylinder 1, thereby slowing down the growth of bacteria.

[0080] The first pipe 3, the second pipe 4 and the fourth pipe 7 are all detachably connected to the barrel cover 11. A connecting portion is provided on the inner bottom wall of the barrel body 12, and one end of the third pipe 5 is threadedly connected to the connecting portion. Through the above arrangement, the filter element 2 can be prevented from shaking. Moreover, it is only necessary to twist the barrel cover 11 to rotate the third pipe 5 relative to the connecting portion, so that the barrel cover 11 together with the first pipe 3, the second pipe 4, the third pipe 5, the fourth pipe 7 and the filter element 2 can be removed to facilitate the replacement of components. The central water purifier also includes tools such as a wrench 8 for opening the barrel cover 11. A pressure relief hole is also provided on the top of the barrel cover 11, and a pressure relief valve is provided at the pressure relief hole to relieve pressure when the pressure is too high.
