Description

Technical Field

[0001] The invention relates to the technical field of portable water purifiers, in particular to a portable water purifier with a self-priming filtering structure. Background Art

[0002] In recent years, adventure and mountaineering have been very popular among extreme sports enthusiasts. Outdoor water sources may contain a large number of pathogenic bacteria and suspended turbidity. These uncertain factors are undoubtedly a threat to our health. On the other hand, carrying water heating devices or bottled drinking water will also be a burden for outdoor sports. In order to meet these two requirements, portable micro water purifiers for outdoor adventures came into being;

[0003] Portable water purifiers are portable water purification products that can directly filter outdoor river water, stream water, spring water and other fresh water containing harmful bacteria and odor into direct drinking water. They are mainly divided into bottle type, pump type and straw type. According to the invention patent with publication number CN117599489A, it involves cleaning the filter element in the portable water purifier. When the rotating rod rotates, it can drive multiple first bevel gears to rotate synchronously. When the multiple first bevel gears rotate, they drive multiple third bevel gears to rotate synchronously. The third bevel gear drives the reciprocating screw to rotate. Through the triangular groove to limit the triangular wire sleeve, the triangular wire sleeve can drive the brush to move up and down along the reciprocating screw, so as to realize the cleaning of the inner wall of the filter element.

[0004] However, for portable water purifiers, their simple structure limits the number and types of filter cartridges that can be stored. Therefore, the filter cartridges are also optimized and designed, and the traditional multiple filter cartridges are organically combined. The cleaning effect of the filter cartridges by traditional brushing is not obvious. At the same time, the traditional portable water purifiers also lack online detection of outdoor water quality and cannot provide users with a suitable drinking purified water source. With the limited purification effect of the portable water purifier, it is very easy for users to drink purified water with relatively serious pollution, resulting in the occurrence of adverse symptoms.

[0005] To this end, we propose a portable water purifier with a self-priming filtration structure. Summary of the invention

[0006] The object of the present invention is to provide a portable water purifier with a self-priming filtering structure to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: a portable water purifier with a self-priming filtering structure, comprising a protective shell, a filter cartridge fixed in the protective shell by bolts, an activated carbon cover installed and fixed in the filter cartridge, a laminate evenly slidably connected to the outer wall of the activated carbon cover, a pressure plate slidably connected to the outer wall of the activated carbon cover and located on the laminate side, and a suction mechanism fixed in the filter cartridge and located on the inner side of the movable carbon cover by bolts;

[0008] A connecting cylinder is fixed to one side of the filter cylinder by bolts, a one-way valve is installed on the opposite side of the connecting cylinder and the filter cylinder, a combined filter element is fixed in the connecting cylinder by bolts, and a liquid outlet pipe is connected and fixed to one side of the connecting cylinder.

[0009] Furthermore, a micro water pump is fixed to the outer wall of the protective shell by bolts, the water inlet side of the micro water pump is connected to a liquid guide tube, and an anti-blocking cover is installed at one end of the liquid guide tube.

[0010] Furthermore, a water body detector is installed on the top of the protective shell. The water body detector is located inside the protective shell and is connected to a micro water pump through a pipeline. The pipeline on the other side of the water body detector is connected to the filter cartridge.

[0011] Furthermore, a liquid storage cylinder is fixed in the protective shell by bolts, a connecting pipe on the water body detector is connected to the liquid storage cylinder, and a sewage pipe is provided at the bottom of the protective shell.

[0012] Furthermore, a through pipe is installed on the outer wall of the liquid outlet pipe, a flushing funnel is installed on the protective shell, and one end of the flushing funnel is connected to the through pipe.

[0013] Furthermore, the suction mechanism includes a cylinder shell, a water outlet chamber and a water inlet chamber. The inner side of the activated carbon cover is fixedly connected to the cylinder shell. The cylinder shell is provided with a water outlet chamber and a water inlet chamber. A sealing ball 1 is installed in the water outlet chamber, and a sealing ball 2 is installed in the water inlet chamber.

[0014] Furthermore, a clamping cylinder is fixed to the outer wall of the filter cover by bolts, a push sleeve is fixed to one side of the pressure plate by bolts, and one side of the push sleeve passes through the protective shell and is fixed with a lock handle by spot welding, a piston column is slidably connected inside the push sleeve, and one end of the piston column passes through the filter cylinder and the pressure plate respectively and extends into the cylinder shell.

[0015] Among them, the method of using the portable water purifier with a self-priming filtration structure is:

[0016] Self-priming water inlet detection: by immersing the anti-blocking cover of the liquid guide pipe section on the side of the micro water pump in the water sample collection area, the micro water pump draws in water samples along the pipeline into the liquid storage cylinder when working, and the water body detector installed in the protective shell starts to perform multi-parameter detection of water quality in the liquid storage cylinder. During the water quality detection process, multiple water quality parameters, including COD, total phosphorus, total nitrogen, and ammonia nitrogen data are compared. The water quality with a single data exceeding the standard is actively discharged from the protective shell, and the water quality with a single data not exceeding the standard is actively purified, and marked and displayed uniformly on the water body detector;

[0017] Auxiliary pressurized filtration, when the water quality that does not exceed the standard is obtained, the pipeline on the water detector discharges the water into the filter cartridge. At the same time, the user manually pulls the piston column on the cartridge side. The water entering the filter cartridge first passes through the interception filtration of the multi-layer stacked sheets, and then passes through the activated carbon cover to the cartridge shell side. After pressure is applied to the piston column, when the piston column is pulled, the water flow on the water inlet chamber side lifts the sealing ball 2 and enters the cartridge shell. The piston column pushes inward, which pushes the water into the connecting tube. The water pressure of the water flowing into the connecting tube increases, and gradually passes through the combined filter element and is discharged from the liquid outlet pipe to complete the acquisition of purified water.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, by installing the filter components in a precisely corresponding manner in the protective shell, for the set coarse filter components, the multiple groups of laminated sheets installed in the filter cartridge are extruded and arranged to intercept large particles of impurities in the water body, and the activated carbon cover is used to remove the odor of the water body, forming an interception barrier in the early stage of water filtration, avoiding direct filtration of sewage by the filter element, accelerating the loss of the filter element, and blocking the small holes on the surface of the filter element, affecting the normal water outlet rate. For the initially intercepted water body, in order to increase the flow rate, artificial pressure is applied to push the piston column while completing the water purification activity, and finally the combined filter element installed in the connecting cartridge is used to achieve fine filtration of water quality and improve the water purification effect;

[0020] 2. In the present invention, by setting up a backwashing structure for the laminations, compared with the replacement of the combined filter element, pure water is added by using the flushing funnel side, and the clean water flows through the inner side of the filter element in turn, and enters the inner side of the activated carbon cover through the one-way valve, and at the same time, the push sleeve on the pressure plate on the side of the laminations is rotated to achieve relaxation of multiple groups of laminations, and the large particles of impurities intercepted between the laminations are flushed away with continuous water flow from the inside to the outside, and then discharged uniformly through the sewage pipe at the bottom of the protective shell, thereby extending the service life of the entire lamination;

[0021] 3. In the present invention, a water body detector is installed in the protective shell, and water is continuously absorbed by a micro water pump on the protective shell, and is introduced into a liquid storage cylinder through a pipeline for storage. Water quality detection is performed in conjunction with the water body detector. After the acquired water quality is detected, an automatic alarm is triggered if the water body does not meet the set standard, prompting the operator to change the water quality, so as to avoid the portable water purifier being unable to fully intercept impurities during heavy sewage filtration, resulting in adverse symptoms for users after drinking.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-8 , the present invention provides a technical solution:

[0033] Example 1: A portable water purifier is a portable micro water purification product that directly filters source water and converts it into drinking water by installing and combining different filter cartridges. It is required to be small and easy to carry. With the emergence of diversified portable water purifiers on the market, the efficient purification effect is combined with intelligent water body detection to provide a safer outdoor drinking water environment.

[0034] like Figure 1 and Figure 2As shown, the entire portable water purifier adopts a waterproof shell, and a micro water pump 17 is installed on one side of the protective shell 1, which is convenient for operators to automatically suck water from different areas into the protective shell 1. Secondly, the portable water purifier is equipped with a power supply to assist work, and a compass is also equipped on the top of the shell, and the comprehensive functions are relatively comprehensive;

[0035] When in use, the liquid guide tube 18 is installed to the water inlet end of the micro water pump 17, and then the other end of the liquid guide tube 18 with the anti-blocking cover 19 is immersed in the collection water area, and the micro water pump 17 is started to pump water. Figure 3 As shown, one end of the outlet pipe of the micro water pump 17 is connected to the water body detector 2, and the other end is connected to the liquid storage cylinder 20;

[0036] The protective shell 1 is equipped with a water body detector 2, and is connected to a liquid storage cylinder 20. The water body detector 2 continuously detects the water discharged into the liquid storage cylinder 20. The water body detector 2 can generally detect multiple water quality parameters in a short time, including COD, total phosphorus, total nitrogen, ammonia nitrogen and turbidity, among which ammonia nitrogen detection time is longer and turbidity detection is the fastest. Therefore, the storage cylinder is used to obtain the water body of the water area, and the water body detection is performed during the carrying and moving process, so as to obtain more comprehensive water quality data;

[0037] Usually, the thresholds of various water quality data can be manually adjusted. When the water quality data of the collection area has a large deviation, the sewage in the liquid storage cylinder 20 is actively controlled to be discharged without deep purification treatment, so as to avoid sewage contamination of the entire purification filter element. For qualified water quality, it can flow into the filter cylinder 4 normally.

[0038] like Figure 4 As shown, multiple groups of PP stacks 5 are evenly and slidably connected in the entire filter cartridge 4, and are compressed by a pressing plate 15 installed at the end of the stack 5. At the same time, the push sleeve 7 connected to the side of the pressing plate 15 extends to the outside of the protective shell 1. In order to facilitate the locking of the pressing plate 15 and the fixing of the push sleeve 7, a cartridge 6 is also fixedly connected to the side of the filter cartridge 4, and a groove is opened on the outer wall of the cartridge 6. At the same time, a lock handle 14 is welded and fixed to the outer wall of the push sleeve 7. The lock handle 14 is manually squeezed on the push sleeve 7, and the side pressing plate 15 of the stack 5 is stabilized by rotating the lock handle 14 into the outer wall groove of the cartridge 6. When the stack 5 needs to be washed, the lock handle 14 can be released, and the pressing pressure of the pressing plate 15 on the stack 5 is reduced. In the relaxed state, it is convenient to remove impurities intercepted between the stacks 5.

[0039] like Figure 5 As shown, after removing the multiple stacks 5 and the activated carbon cover 13 in the filter cartridge 4, the suction mechanism 9 is revealed, wherein the activated carbon cover 13 installed is used for deodorization, removal of heavy metals in water, dechlorination and liquid decolorization, and the entire suction mechanism 9 is installed to improve the efficiency of the portable water purifier in purifying water quality, combined with the common piston pumping structure, such as Figure 6As shown, the flow direction of the entire water body is indicated by the arrow in the figure. The water body that initially enters the filter cartridge 4 is first filtered by the laminated sheets 5 to intercept large particles of impurities in the water body. With the continuous operation of the micro water pump 17, the water body gradually overflows the activated carbon cover 13 and reaches the outside of the cartridge shell 901;

[0040] At this time, the operator needs to push and pull the piston rod 8 installed on the side of the push sleeve 7, combined with Figure 7 When the piston column 8 moves to the right, the suction force generated drives the sealing ball 905 on the side of the water inlet chamber 903 to move, so that the cylinder shell 901 can extract water. On the contrary, when the piston is squeezed to the left, the water flow in the cylinder shell 901 moves to the left uniformly. At this time, the water flow gives the sealing ball 905 a downward thrust, which makes it impossible to discharge. As for the sealing ball 904 installed on the side of the water outlet chamber 902, it is pushed by the water flow and separated from the abutment against the hole. At this time, the water flow is discharged into the connecting cylinder 10 along the side outlet of the water outlet chamber 902. With the continuous pulling and pushing of the piston column 8, the water flow that continuously flows into the connecting cylinder 10 begins to perform a secondary filtering operation;

[0041] The combined filter element 11 is installed in the entire connecting cylinder 10, and the entire combined filter element 11 uses a high-precision ceramic filter element as the outer layer, ion exchange resin as the filling, and filter cotton inside. The water flow after multi-layer filtration is finally discharged from the combined filter element 11 to the liquid outlet pipe 21 on one side, completing the entire sewage purification operation;

[0042] The filter components are installed in the protective shell 1 in a precisely corresponding manner. For the coarse filter components, the multiple groups of laminated sheets 5 installed in the filter cartridge 4 are extruded and arranged to intercept large particles of impurities in the water body, and the activated carbon cover 13 is used to remove odor from the water body to form an interception barrier in the early stage of water filtration. Subsequently, a refined combined filter element 11 is set to clean and adsorb fine impurities in the water, thereby achieving efficient purification of the water quality.

[0043] Embodiment 2: With the use of the entire portable water purifier, the entire combined filter element 11 needs to be replaced, and the multiple laminates 5 installed on the outside of the activated carbon cover 13, due to their own combination distribution and special structure, only need to be rinsed and reused;

[0044] For this reason Figure 1 and Figure 3As shown, a flushing funnel 3 is also installed on the outer wall of the entire protective shell 1, and a through-tube 22 is installed on the outer wall of the liquid outlet pipe 21. Under normal circumstances, the entire portable water purifier does not need to be installed on the through-tube 22, so the through-tube 22 is in a closed state and does not affect the normal discharge of the water outlet pipe. When the filter material related to the portable water purifier is replaced and cleaned, the flushing funnel 3 needs to be installed on the through-tube 22. The installation of the flushing funnel 3 and the through-tube 22 makes the through-tube 22 open, and the operator pours pure water from the side of the flushing funnel 3 and seals one end of the liquid outlet pipe 21 at the same time;

[0045] The backwash water flow direction of the entire stack 5 is as follows Figure 8 As shown, the pure water discharged from the flushing funnel 3 enters the connecting tube 10 along the liquid outlet pipe 21, and then flows into the inner side of the entire combined filter element 11, as shown in FIG. Figure 6 As shown, a one-way valve 12 is installed at the connection between the entire connecting cylinder 10 and the filter cylinder 4, so that the water flow can only flow from the combined filter element 11 to the filter cylinder 4, and the sewage in the filter cylinder 4 cannot be directly discharged into the combined filter element 11 through the one-way valve 12;

[0046] At this time, the pure water enters the filter cartridge 4 along the one-way valve 12 and flows from the inside to the outside. However, due to the squeezing of the pressure plate 15 between the laminates 5, it is difficult to discharge the impurities in the gap between the laminates 5. At this time, the operator needs to turn the lock handle 14 on the side of the push sleeve 7, and the laminates 5 that are not squeezed are in a relaxed state. At this time, the pure water is continuously discharged to wash away the impurities between the laminates 5. When the sewage pipe 16 on the side of the protective shell 1 is opened, the sewage is continuously discharged. During the whole flushing process, it should be noted that the pure water needs to completely fill the filter cartridge 4. At this time, the sewage pipe 16 is opened, that is, the sewage pipe 16 is in an intermittent switch to ensure the maximum flushing effect.
