Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and in particular to a multi-stage filter element filtering device for a water purifier and a filtering method thereof. Background Art

[0002] The multi-stage filter element filtration device of a water purifier is a device that uses a variety of filter media and technologies to filter water layer by layer. It is designed to effectively remove various impurities, pollutants and microorganisms in the water and provide clean and safe drinking water. The multi-stage filter element filtration device uses filter media of different types and particle sizes, such as granular activated carbon, ceramic filter elements, ultrafiltration membranes, reverse osmosis membranes, etc. These filter media can effectively remove different types of pollutants such as suspended solids, organic matter, heavy metals, microorganisms, etc. in the water to ensure the safety and cleanliness of the water quality.

[0003] There are still the following defects in specific use:

[0004] 1. Most of the existing adsorbents are fixedly installed inside the water purifier and do not move. Fixed adsorbents inside the water purifier may cause water to stay on the adsorbent in a specific area for too long, causing local saturation of the adsorbent and affecting the overall adsorption effect. In addition, if the adsorption surface of the adsorbent is affected by the accumulation of pollutants and no mobile vibration cleaning is performed, the effective adsorption area of ​​the adsorbent surface will be reduced, thereby reducing the filtration efficiency of the water purifier. At the same time, failure to perform mobile vibration cleaning may cause pollutants to accumulate on the adsorbent surface, accelerate the aging and clogging of the filter element, shorten the service life of the water purifier, and increase maintenance costs.

[0005] 2. In addition, if the water flow in the water purifier is not properly guided and distributed, it may cause uneven water flow distribution in the filter, which will cause some areas to be over-filtered while other areas are less filtered, reducing the filtration efficiency. Without restricting the movement of water flow, it is easy for sediment to accumulate at the water outlet. Over time, the accumulation of sediment may block the water outlet, affecting the smooth flow of water, and even causing water backflow or siltation, and the water flows out of the outlet at an unstable speed, which may affect the filtration effect inside the water purifier, causing the water flow to stay in the filter medium for insufficient time and unable to achieve sufficient filtration effect.

[0006] In view of this, the present invention proposes a multi-stage filter element filtering device for a water purifier and a filtering method thereof to remedy and improve the deficiencies of the prior art. Summary of the Invention

Slide rails are fixedly installed on the upper surfaces of the two fixed plates. A movable brush plate is slidably connected to the inside of the two slide rails.

[0011] The amplitude adjustment component is used to adjust the amplitude frequency of the movable brush plate.

The inner wall of the first clip is rotatably connected to a crank, and the outer wall of the sleeve shaft close to the sleeve is fixedly installed with a second clip. The central outer wall of the sleeve shaft is fixedly installed with a connecting buckle, and a threaded rod is provided through the inner wall of the connecting buckle.

[0012] The diversion mechanism includes a driving component, a diversion component and a cleaning component, the driving component is used to keep synchronous movement with the driving shaft, the driving component is installed inside the water purifier body and is located between the diversion component and the oscillation component, so that the water pre-filtered by the pre-filter is filtered through the activated carbon filter after the water flow is adjusted by the driving component, and finally flows into the particle adsorption filter for filtration, the driving component includes a transmission belt connected to the outer wall of the driving shaft, and two transmission belts are symmetrically arranged about the central axis of the driving shaft, and the ends of the two transmission belts away from the driving shaft are fixedly installed with half-tooth gears, and toothed wheels are arranged below the two half-tooth gears, and a rotating ring is fixedly installed on the side of the two toothed wheels away from the inner wall of the water purifier body, and a block is clamped on the outer wall of the rotating ring away from the toothed wheel.

[0014] The cleaning component is used to clean the inner wall of the water purifier body. The cleaning component includes a brush fixedly installed on the outer wall of the movable brush plate. There are multiple brushes, and the material of the brush is nylon.

[0015] The multi-stage filter element filtration method of the water purifier comprises the following steps:

[0016] Step 1: Water is input into the water purifier through the water inlet;

[0017] Step 2: The water first passes through the pre-filter, where large particles of impurities such as silt and rust are filtered out to protect the subsequent filters and extend their service life. At the same time, the pre-filter is used in conjunction with the vibration mechanism to vibrate the filter medium, helping to more effectively release and adsorb impurities in the water into the filter material, which helps to improve filtration efficiency and ensure purer water quality.

[0018] Step 3: The water then passes through the activated carbon filter, where organic compounds, residual chlorine, odor, etc. are adsorbed, improving the taste and quality of the water. The water then enters the particle adsorption filter, where tiny particles and suspended solids are adsorbed, further improving the clarity of the water. When entering the activated carbon filter and the particle adsorption filter, a diversion mechanism is used to adjust the distribution of the water flow, ensuring that the water flow is evenly distributed in different filtration channels, avoiding the problem of excessive water flow in some channels resulting in uneven filtration effect;

[0019] Step 4: The water passes through the reverse osmosis membrane, where dissolved solids, heavy metals, bacteria, etc. are intercepted, thereby purifying the water quality. In order to completely eliminate microorganisms in the water, the water passes through an ultraviolet sterilizer, where ultraviolet radiation kills bacteria, viruses and other microorganisms. Finally, after the above multiple filtration treatments, the purified water is output and can be directly used or drunk by people.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention utilizes the driving shaft and the sleeve and the movable brush plate to cooperate with each other. The oscillation mechanism can help to release and adsorb impurities in the water more effectively into the filter material by vibrating the filter medium, which helps to improve the filtration efficiency and ensure that the water quality is purer. The oscillation mechanism can help the movable brush plate to contact the water flow evenly, thereby enhancing the contact between the pollutants and the movable brush plate, which helps to improve the removal efficiency of the water purifier body, especially for suspended particles and soluble substances. In addition, the oscillation mechanism can prevent pollutants from accumulating on the movable brush plate, thereby reducing the impact of pollutants on the performance of the water purifier body. By regular oscillation, pollutants can be removed from the movable brush plate, maintaining the high efficiency of the movable brush plate. Regular oscillation of the movable brush plate can reduce the accumulation and accumulation of pollutants and extend the service life of the movable brush plate, which helps to reduce maintenance costs and improve the reliability of the water purifier body. By vibrating the movable brush plate, scaling or clogging on the surface of the movable brush plate can be prevented, keeping the water flow smooth.

[0022] (2) The present invention utilizes the connecting shaft plate and the rotating ring and the baffle to cooperate with each other. The diversion mechanism can help guide the water flow so that it is more uniform before entering the next stage filter. This helps to ensure that the water flow is evenly distributed over the entire filter surface, thereby improving the filtration effect and ensuring that each part is properly filtered. In addition, before the water flow enters the next stage filter, the reciprocating baffle can disperse and guide the water flow, thereby slowing down the water flow speed. This is very important for controlling the water flow speed, especially when the water flow rate is large or the water flow speed is too fast, which can reduce the flow of water inside the water purifier body. Furthermore, the movement of the reciprocating baffle can break up the suspended matter in the water and prevent sediment from accumulating at the water outlet, which helps to keep the water clean and reduce the accumulation of bottom mud.

[0023] (3) The present invention utilizes a movable brush plate and a brush to cooperate with each other. The brush can clean the inner wall of the water purifier body regularly to remove dirt, bacteria and other impurities, and prevent them from accumulating and breeding inside the water purifier body, thereby keeping the interior of the water purifier body clean and hygienic. In addition, regular cleaning of the inner wall of the water purifier body can prevent the accumulation and accumulation of dirt, reduce the wear and damage to the filter and other components, thereby extending the service life of the water purifier body, and keeping the interior of the water purifier body clean can ensure the normal operation of the filter and other purification devices, ensure their optimal filtering effect, and thus produce cleaner and healthier drinking water. Finally, combined with the brush cleaning mechanism, the inner wall of the water purifier body can be cleaned regularly and automatically, reducing the frequency of manual cleaning, improving the convenience and user experience of the water purifier body, and regular cleaning of the inner wall of the water purifier body can effectively prevent the breeding of bacteria and other harmful microorganisms, and ensure the hygienic safety of the output water quality; BRIEF DESCRIPTION OF THE DRAWINGS

The surface of the movable brush plate 211 is provided with a plurality of through holes. When the drive shaft 22 rotates, the concave surface of the outer wall of the drive shaft 22 conflicts with the convex portion of the inner wall of the sleeve 24, causing the sleeve 24 to swing left and right.

[0047] Example 2

[0048] The multi-stage filter element filtration method of the water purifier comprises the following steps:

[0049] Step 1: Water is input into the water purifier body 1 through the water inlet 13;

[0050] Step 2: The water first passes through the pre-filter 14, where large particles of impurities such as silt, rust, etc. are filtered out to protect the subsequent filters and extend their service life. At the same time, it is used in conjunction with the vibration mechanism 2 to vibrate the filter medium, helping to more effectively release and adsorb impurities in the water into the filter material, which helps to improve the filtration efficiency and ensure purer water quality.

[0051] Step 3: The water then passes through the activated carbon filter 15, where organic compounds, residual chlorine, and odors are adsorbed, improving the taste and quality of the water. The water then enters the particle adsorption filter 16, where tiny particles and suspended solids are adsorbed, further improving the clarity of the water. When the water enters between the activated carbon filter 15 and the particle adsorption filter 16, the diversion mechanism 3 is used to adjust the distribution of the water flow, ensuring that the water flow is evenly distributed in different filtration channels, avoiding the problem of excessive water flow in some channels resulting in uneven filtration effect;

[0052] Step 4: The water passes through the reverse osmosis membrane, where dissolved solids, heavy metals, bacteria, etc. are intercepted, thereby purifying the water quality. In order to completely eliminate microorganisms in the water, the water passes through the ultraviolet sterilizer, where ultraviolet radiation kills bacteria, viruses and other microorganisms. Finally, after the above multiple filtration processes, the purified water is output and can be directly used or drunk by people;

[0053] The following are the complete usage steps and working principles of the above embodiment:

[0054] The device is mainly used for: Figure 1 As shown, the operator uses the water inlet 13 to pass water into the interior of the water purifier body 1. The water source undergoes pre-filtration, activated carbon filtration, particle adsorption filtration, reverse osmosis treatment and ultraviolet disinfection. After the above multiple filtration processes, the purified water is output and can be directly used or drunk by people;

[0055] The vibration mechanism 2 is used to vibrate the filter medium to help release and adsorb impurities in the water more effectively into the filter material. When used specifically:

[0056] like Figure 3 As shown, the operator connects an external motor to the output end of the drive shaft 22, and then the motor starts to drive the drive shaft 22 to rotate. In addition, the outer wall of the drive shaft 22 is fixedly mounted with a sleeve 24, so the rotation of the drive shaft 22 will also drive the sleeve 24 to rotate. Figure 4 As shown, the outer wall of one end of the drive shaft 22 close to the sleeve 24 is concave, and the inner wall of the sleeve 24 is provided with a convex portion. Therefore, when the drive shaft 22 rotates, the concave surface of the outer wall of the drive shaft 22 conflicts with the convex portion of the inner wall of the sleeve 24, causing the sleeve 24 to swing left and right. In addition, an obstacle column 210 is slidably connected to the inner wall of the sleeve 24, and a movable brush plate 211 is fixedly installed on the upper surface of the obstacle column 210, and the movable brush plate 211 is slidably connected to the inner wall of the slide rail 212. Therefore, the left and right shaking of the sleeve 24 will drive the movable brush plate 211 to move on the slide rail 212. The inner wall of the sleeve 24 slides left and right, and the outer wall of the drive shaft 22 is also sleeved with a sleeve 23. At the same time, the outer wall of the sleeve 24 and the outer wall of the sleeve 23 are respectively fixedly mounted with a first clip 25 and a second clip 27. The inner walls of the first clip 25 and the second clip 27 are also rotatably connected with a crank 26. Therefore, the operator can move the sleeve 23 on the drive shaft 22 by twisting the threaded rod 29, thereby deflecting the crank 26, thereby controlling the swing amplitude of the sleeve 24, and controlling the left and right movement rate of the movable brush plate 211 by the swing amplitude of the sleeve 24.

[0057] Summary 1: Compared with the existing technology which only fixes the adsorbent inside the water purifier body 1 to adsorb impurities, this mechanism realizes that when the drive shaft 22 rotates, the concave surface of the outer wall of the drive shaft 22 conflicts with the convex part of the inner wall of the sleeve 24, which will cause the sleeve 24 to swing left and right. Therefore, the left and right shaking of the sleeve 24 will drive the movable brush plate 211 to slide left and right on the inner wall of the slide rail 212. The oscillation mechanism 2 can help to release and adsorb impurities in the water more effectively into the filter material by vibrating the filter medium, which helps to improve the filtration efficiency and ensure that the water quality is purer. In addition, the oscillation mechanism 2 can help the movable brush plate 211 to contact the water flow evenly, thereby enhancing the contact between the pollutants and the movable brush plate 211. The contact between the movable brush plate 211 and the movable brush plate 211 is conducive to improving the removal efficiency of the water purifier body 1, especially for suspended particles and dissolved substances. In addition, the oscillation mechanism 2 can prevent the accumulation of pollutants on the movable brush plate 211, thereby reducing the impact of pollutants on the performance of the water purifier body 1. By oscillating regularly, pollutants can be removed from the movable brush plate 211, maintaining the high efficiency of the movable brush plate 211, and regularly oscillating the movable brush plate 211 can reduce the accumulation and accumulation of pollutants, extending the service life of the movable brush plate 211, which helps to reduce maintenance costs and improve the reliability of the water purifier body 1. By oscillating the movable brush plate 211, scaling or clogging on the surface of the movable brush plate 211 can be prevented, thereby maintaining smooth water flow.

[0058] Used to adjust the distribution of water flow and ensure that the water flow is evenly distributed in different filter channels. The specific use of the diversion mechanism 3 is:

[0059] like Figure 5 As shown, a transmission belt 31 is also connected to the outer wall of the drive shaft 22. When the drive shaft 22 rotates, the transmission belt 31 is driven to rotate together. Moreover, a half-tooth gear 32 is fixedly mounted on the outer wall of the transmission belt 31, and the half-tooth gear 32 and the toothed wheel 33 are meshed with each other. Therefore, when the transmission belt 31 rotates, the half-tooth gear 32 and the toothed wheel 33 are synchronously driven to rotate. In addition, a rotating ring 34 is fixedly mounted on the outer wall of one side of the toothed wheel 33, and a card block 35 is clamped on the outer wall of the rotating ring 34. Therefore, the rotation of the toothed wheel 33 also drives the rotating ring 34 to rotate, and then as shown in FIG. Figure 6As shown, the rotation of the rotating ring 34 will cause the block 35 to pull the rod connecting block 36 that is rotatably connected to the outside of the block 35 to slide inside the slide groove body 37. As the rod connecting block 36 slides inside the slide groove body 37, the telescopic rod 38 connected to the outer wall of the rod connecting block 36 will be driven to extend and retract. When the rod connecting block 36 slides inside the slide groove body 37 toward the side close to the rotating ring 34, the rod connecting block 36 pulls the telescopic rod 38 to extend toward the side close to the rotating ring 34. Then, the extension of the telescopic rod 38 will cause the connecting rod 39 to deflect toward the side close to the rotating ring 34. The deflection of the connecting rod 39 will drive the connecting shaft plate 310 to move away from One side of the rotating ring 34 is deflected, and then the baffle 311 is rotatably connected to the inner wall of the water purifier body 1, thereby the connecting shaft plate 310 causes the baffle 311 to deflect upward. Similarly, when the rod connecting block 36 pulls the telescopic rod 38 to retract away from the rotating ring 34, the retraction of the telescopic rod 38 causes the connecting rod 39 to deflect away from the rotating ring 34. Thus, the deflection of the connecting rod 39 drives the connecting shaft plate 310 to deflect toward the side close to the rotating ring 34. In this way, the connecting shaft plate 310 causes the baffle 311 to deflect downward. Then, through the up and down deflection and swing of the baffle 311, the water flow can flow evenly and slowly into the next channel.

[0060] Summary 2: Compared with the prior art in which water flows directly into the filtration channel, this mechanism realizes that the deflection of the connecting rod 39 will drive the connecting shaft plate 310 to deflect to the side away from the rotating ring 34, and then the baffle 311 is rotatably connected to the inner wall of the water purifier body 1, so that the connecting shaft plate 310 will cause the baffle 311 to deflect upward, and the deflection of the connecting rod 39 will drive the connecting shaft plate 310 to deflect to the side close to the rotating ring 34, so that the connecting shaft plate 310 will cause the baffle 311 to deflect downward, and then through the up and down deflection swing of the baffle 311, the water flow can flow into the next channel evenly and slowly, and the diversion mechanism 3 can help guide the water flow so that it enters the next channel. The reciprocating baffle 311 can disperse and guide the water flow before entering the next filter stage, thereby slowing down the water flow speed, which is very important for controlling the water flow speed, especially when the water flow rate is large or the water flow speed is too fast, which can reduce the flow of water inside the water purifier body 1. Moreover, the movement of the reciprocating baffle 311 can break up the suspended matter in the water and prevent the sediment from accumulating at the water outlet, which helps to keep the water clean and reduce the accumulation of bottom mud.

[0061] The brush 444 mechanism for cleaning the inner wall of the water purifier body 1 is specifically used as follows:

[0062] like Figure 7As shown, when the movable brush plate 211 is moving left and right, since a plurality of brushes 444 are fixedly installed on the outer wall of the movable brush plate 211, the movement of the movable brush plate 211 will also drive the brushes 444 to clean the inner wall of the water purifier body 1;

[0063] Summary 3: Compared with the prior art which is difficult to clean the dirt on the inner wall of the water purifier main body 1, the present mechanism realizes that the movement of the movable brush plate 211 will also drive the brush 444 to clean the inner wall of the water purifier main body 1. The brush 444 cleans the inner wall of the water purifier main body 1 to regularly remove dirt, bacteria and other impurities, and prevents them from accumulating and breeding inside the water purifier main body 1, thereby keeping the interior of the water purifier main body 1 clean and hygienic. In addition, regularly cleaning the inner wall of the water purifier main body 1 can prevent the accumulation and accumulation of dirt, reduce the wear and damage to the filter and other components, thereby extending the service life of the water purifier main body 1, and keeping the interior of the water purifier main body 1 clean can ensure the normal operation of the filter and other purification devices, ensure their optimal filtering effect, thereby producing cleaner and healthier drinking water. Finally, combined with the brush 444 cleaning mechanism, the inner wall of the water purifier main body 1 can be cleaned automatically and regularly, reducing the frequency of manual cleaning, improving the convenience and user experience of the water purifier main body 1, and regularly cleaning the inner wall of the water purifier main body 1 can effectively prevent the breeding of bacteria and other harmful microorganisms, and ensure the hygienic and safe output water quality.
