Description

TECHNICAL FIELD

[0001] The utility model belongs to the drinking water filtration technical field, specifically relates to a purifying water cup. BACKGROUND

[0002] Water as the source of human life has irreplaceable effect, and water pollution is increasingly serious. 70% of rivers and lakes in China are polluted to varying degrees, and more than 300 million people's drinking water is unsafe. Nowadays, with the improvement of living standards, more and more people choose to go out of doors to feel the unique charm of nature. When people go outdoors, they often have the condition of insufficient self-provided drinking water. In the case of extreme natural disaster emergency, due to the limitation of conditions, people cannot completely clean the water source in the wild before drinking, and cannot effectively isolate the harmful substances such as bacteria and heavy metal ions in the water, which are harmful to human body, which is easy to cause people to get sick after drinking water, and even endanger life safety in serious cases.

[0003] In many domestic and foreign water purification cup products, the filter core material is generally selected from one or several active materials such as granular activated carbon. These materials are directly combined and installed in the water purifier. Although this method can remove heavy metals, pesticides and organic matter, it cannot effectively sterilize bacteria, because bacteria will accumulate and reproduce on these adsorption materials. In order to sterilize, the active material needs to be treated with silver infiltration or chlorine and iodine. This will cause secondary pollution and complex process. At present, the filter core of the water purification cup selects KDF as the filter material to achieve the purpose of sterilization. However, KDF is easy to form a block in the use process, which increases the pressure loss, thereby affecting the water flow rate and the water purification effect, and the copper and zinc ion concentration of the outlet water increases. Moreover, the existing filter core is usually replaced as a whole after use, which greatly increases the use cost. In addition, due to the integral structure of the filter core, the humidity in the filter material is high after use, which is easy to breed bacteria and cause secondary pollution. SUMMARY

[0035] The outer surface of the rotating cover body 24 of the cup cover 3 is provided with an anti-skid rubber ring 35, 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 is rotatable relative to the fixed cover body 23, and when the matching clamping point 29 and the locking clamping point 28 abut, the inclined extrusion table 31 extrudes the straw 26 to be bent in the limiting ring table 34 on the surface of the fixed cover body 23, and the straw 26 is completely closed by extrusion, and the bent straw 26 is pressed on the ventilation hole, so that the water storage shell 5 is sealed with the outside.

[0037] The rotating cover body 24 and the fixed cover body 23 are in a split structure, can be disassembled for easy cleaning, and the inside of the fixed cover body 23 in the cup cover 3 is provided with an ultraviolet disinfection lamp 36.

[0038] The principle of the utility model is as follows: when the purified water cup is in a closed and unopened state, the matching clamping point 29 on the rotating cover body 24 in the cup cover 3 abuts against the locking clamping point 28 in the fixed cover body 23, at this time, the inclined extrusion table 31 extrudes the straw 26, the straw 26 is bent and laid in the limiting ring table 34, the top of the straw 26 abuts against the ventilation hole, and the straw 26 is extruded and closed by the extrusion of the inclined extrusion table 31, so that the inside of the filter main body 2 is in a sealed state;

[0039] When the purified water cup is needed to filter outdoor water, first rotate the cover 24 counterclockwise, and the matching card point 29 is resisted on the pre-tightening card point 27. At this time, counterclockwise rotation of the inclined extrusion table 31 will loosen the suction pipe 26 but not completely disconnect, the suction pipe 26 will lift away from the air hole 33, and the suction pipe 26 recovers from the closed state to the open state, making the inside communicate with the atmosphere. Take off the outer bottle body 1, pour water into the outer bottle body 1, and put the filter main body 2 into the outer bottle body 1. By pressing the filter main body 2, the water in the outer bottle body 1 will enter the corresponding ultrafiltration filter 6 from the multiple filter bottom installation holes 9 at the bottom of the ultrafiltration assembly 4. The water is filtered by 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 shell 5 through the water outlet hole 16 in the upper cover 7. When the filter main body 2 is pressed into the outer bottle body 1, the filtration is completed. Open the flip cover 32 to expose the open hole 30, and rotate the cover 24 counterclockwise again. At this time, the suction pipe 26 will recover to a straight state and expose the open hole. The clean water filtered in the water storage shell 5 can be sucked through the suction pipe 26. The fixed cover 23 is also provided with a card point that limits the counterclockwise rotation of the cover 24 to the limit position, and a sliding groove that facilitates the disconnection of the cover 24 and the fixed cover 23.

[0040] The cooperation of the pre-tightening card point 27, the locking card point 28 and the matching card point 29 is not a dead structure. During the process from the completely open state to the closed state, the matching card point 29 will first resist the pre-tightening card point 27. At this time, the suction pipe 26 is in a curved but not closed state. Continue to rotate the cover 24 clockwise, the matching card point 29 will pass the pre-tightening card point 27 and resist the locking card point 28. At this time, the suction pipe 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 limit position card point counterclockwise and come out of the sliding groove, and the cover 24 and the fixed cover 23 are disassembled 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 cover 24.

[0041] After use, the ultrafiltration assembly 4 can be taken off from the water storage shell 5, and the screw structure 20 between the two is disconnected by rotating to separate them. The upper cover 7 can be taken out of the installation shell 8 by using a crowbar or other tools, and the multiple ultrafiltration filters 6 can be taken out for cleaning and drying to prevent bacteria from growing. The installation is the reverse of the above. The ultrafiltration filter 6 is inserted into the filter top installation hole 14 in the upper cover 7, and the bottom of the ring-shaped convex platform is resisted on the bottom of the inlaying hole 18 at the top of the ultrafiltration filter 6 to realize end face sealing. The whole is buckled into the installation shell 8, and the ultrafiltration assembly 4 is connected with the water storage shell 5 to complete the assembly of the filter main body 2.

[0042] Finally, it should be pointed out that the above embodiments are only more representative examples of the present application. Obviously, the present application is not limited to the above embodiments, but can have many variations. Any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments shall be considered as falling within the protection scope of the present application.
