Description

Technical Field

[0001] The invention belongs to the technical field of drinking water filtration, and in particular relates to a water purification cup. Background Art

[0002] Water, as the source of human life, plays an irreplaceable role. When people engage in outdoor activities, they often do not have enough drinking water. In extreme natural disaster emergency situations, due to limited conditions, people cannot completely purify outdoor water sources before drinking, and cannot effectively isolate bacteria, heavy metal ions and other substances harmful to the human body in the water, which can easily cause people to get sick after drinking water, and in serious cases endanger their lives.

[0003] Among the numerous water purifier cup products at home and abroad, the filter element material generally uses one or several active materials such as granular activated carbon. These materials are directly installed in the water purifier after simple combination. Although this can remove heavy metals, pesticides, and organic matter, it cannot effectively sterilize because bacteria will enrich and multiply on such adsorption materials. In order to sterilize, the active materials need to be infiltrated with silver or treated with chlorine or iodine, which will cause secondary pollution and the process is complicated. At present, the filter element of the water purifier cup uses KDF as the filter material to achieve the purpose of sterilization, but KDF is easy to agglomerate into blocks during use, which increases the pressure loss, thereby affecting the flow rate of water and the water purification effect, and the concentration of copper and zinc ions in the outlet water increases a lot. Moreover, the existing filter element is usually replaced as a consumable as a whole after use, which greatly increases the use cost. Moreover, since the filter element is an integral structure, the humidity in the filter material is relatively high after use, which is easy to breed bacteria and cause secondary pollution.

[0034] A vent hole 33 is provided on the right side where the straw 26 is connected to the fixed cover 23 . A limiting ring 34 is provided on the upper surface of the fixed cover 23 . The limiting ring 34 is arranged around the vent hole 33 and the straw 26 .

[0035] The rotating cover body 24 of the cup cover 3 is provided with an anti-skid rubber ring 35 on the outside, and the diameter of the anti-skid rubber ring 35 is consistent with the diameter of the outer bottle body 1 .

[0036] The rotating cover body 24 rotates relative to the fixed cover body 23, and when the matching card point 29 contacts the locking card point 28, the inclined extrusion platform 31 squeezes the straw 26 to bend in the limiting ring platform 34 on the surface of the fixed cover body 23, and the straw 26 is squeezed to be completely closed. At the same time, the bent straw 26 is pressed on the air vent to seal the water storage shell 5 with the outside.

[0037] The rotating cover body 24 and the fixed cover body 23 are separate structures and can be disassembled for easy cleaning; an ultraviolet disinfection lamp 36 is arranged inside the fixed cover body 23 of the cup cover 3.

[0038] Principle of the present invention: When the purified water cup is closed and not opened, the matching card point 29 on the rotating cover body 24 of the cup cover 3 contacts the locking card point 28 in the fixed cover body 23, and at this time, the inclined extrusion platform 31 presses on the straw 26, and the straw 26 bends and falls in the limiting ring platform 34, and the top of the straw 26 presses on the air vent, and the inclined extrusion platform 31 presses on the straw 26 to squeeze the straw 26 closed, so that the filter body 2 is in a closed state;

[0039] When it is necessary to use the purified water cup to filter outdoor water, first rotate the cover body 24 counterclockwise to press the matching card point 29 against the pre-tightening card point 27. At this time, the tilted extrusion platform 31 rotates counterclockwise to loosen the straw 26 but not completely disengage it. The straw 26 will be lifted off the vent hole 33, and the straw 26 will return to the open state from the closed state, so that the interior is connected to the atmosphere. The outer bottle body 1 is removed, and water is poured into the outer bottle body 1. The filter body 2 is placed in the outer bottle body 1 as a whole, and the filter body 2 is pressed downward as a whole. The water in the outer bottle body 1 will enter the corresponding ultrafiltration filter 6 from the multiple filter bottom mounting holes 9 at the bottom of the ultrafiltration assembly 4. In the process, the water is filtered through the hollow fiber filter membrane in the ultrafiltration filter 6, and finally seeps out from the top of the ultrafiltration filter 6, and enters the water storage housing 5 through the water outlet 16 set in the upper cover 7. When the filtering body 2 is pressed into the outer bottle body 1 as a whole, the filtration is completed, and the flip cover 32 is opened to expose the open hole 30, and the rotating cover body 24 is rotated counterclockwise again. At this time, the straw 26 will return to a straight state and be exposed from the opening, and the clean water filtered in the water storage housing 5 can be sucked through the straw 26. The fixed cover body 23 is also provided with a card point that limits the rotating cover body 24 from rotating counterclockwise to the extreme position, and a slide groove is provided to facilitate the disengagement of the rotating cover body 24 from the fixed cover body 23;

[0040] The cooperation of the pre-tightening card point 27, the locking card point 28 and the matching card point 29 are all non-stuck structures. In the process from the fully open state to the closed state, the matching card point 29 will first contact the pre-tightening card point 27. At this time, the straw 26 is in a bent but not closed state. If the rotating cover 24 continues to rotate clockwise, the matching card point 29 will pass the pre-tightening card point 27 and contact the locking card point 28. At this time, the straw 26 is completely closed, and the matching card point 29 cannot pass the locking card point 28. Similarly, the matching card point 29 can pass the card point at the extreme position by rotating counterclockwise and escape from the slide slot, completing the disassembly of the rotating cover 24 and the fixed cover 23, which is convenient for cleaning; the pre-tightening card point 27, the locking card point 28 and the matching card point 29 are symmetrically provided with two groups on the fixed cover 23 and the rotating cover 24;

[0041] After use, the ultrafiltration component 4 can be removed from the water storage shell 5, and the spiral structure 20 between the two can be disengaged by rotating to separate them. The upper cover 7 can be taken out from the installation shell 8 by using tools such as a crowbar, and the multiple ultrafiltration filters 6 can be taken out, cleaned and dried to prevent bacteria from breeding. The installation is similar in reverse. The ultrafiltration filter 6 is inserted into the filter top mounting hole 14 in the upper cover 7, and the bottom of the annular boss is pressed against the bottom of the embedding opening 18 at the top of the ultrafiltration filter 6 to achieve end face sealing. The whole is buckled into the installation shell 8, and the ultrafiltration component 4 is connected to the water storage shell 5 as a whole to complete the assembly of the filter body 2.

[0042] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
