[0003] When using a portable water purifier outdoors, there is a large amount of sediment in the stream water. If the sediment enters the portable water purifier, it will adhere to the filter element in large quantities, causing the filtering effect of the filter element to be greatly reduced. Due to limited outdoor conditions, the existing cleaning method is generally to remove the filter element from the portable water purifier, then put the filter element into the stream water for washing, and then install the filter element back in place after washing before using it again.

[0032] The water treatment component includes a sleeve 103, a handle 104, a connecting column 105, a protrusion 106 and a pressure unit; two sleeves 103 are sleeved on the barrel 1, which are symmetrical in upper and lower directions; each sleeve 103 is fixedly connected to two handles 104 that are symmetrical in left and right directions; the two sleeves 103 are rotatably connected to a connecting column 105 on opposite sides; each connecting column 105 is provided with a winding portion 10501; each connecting column 105 is provided with a plurality of semicircular grooves 10502; each connecting column 105 is connected to an adjacent water inlet pipe 101; a protrusion 106 is fixedly connected to the opposite sides of the two sleeves 103; and a pressure unit is provided on the opposite sides of the two connecting columns 105.

[0033] The pressure unit includes a connecting frame, a first rubber plate 108, and a second rubber plate 109; a connecting frame is fixedly connected to the opposite sides of the two connecting columns 105; all connecting frames located on the same connecting column 105 are commonly fixedly connected to a first rubber plate 108 at one end near the middle of the barrel 1; each first rubber plate 108 is defined by a first through-slot 10801; each first rubber plate 108 is fixedly connected to a second rubber plate 109 on the side near the fixed block 110; each second rubber plate 109 is defined by a second through-slot 10901; each second through-slot 10901 is connected to an adjacent first through-slot 10801; the fixed block 110 is defined by a third through-slot 11001; each third through-slot 11001 is connected to the second through-slot 10901.

[0034] The connecting assembly includes an armrest 201 and a connecting tube 202; the armrest 201 is connected to the front outer side of the tube body 1 in a damping sliding manner; the connecting tube 202 is fixed to the rear side of the armrest 201; the connecting tube 202 is detachably connected and connected to all the first connecting tubes 3; the right side of the connecting tube 202 is detachably connected and connected to the second connecting tube 4.

[0035] First, let's take the sleeve 103 on the upper side as an example. The user puts the water inlet pipe 101 on the lower side into the stream water, then holds the middle of the barrel 1 with one hand and the connecting post 105 on the upper side with the other hand. Based on the view from the top down, the connecting post 105 is rotated 90 degrees clockwise, thereby driving the connecting frame and the first rubber plate 108 to rotate 90 degrees clockwise, so that the first through groove 10801 and the second through groove 10901 change from the initial connected state to the staggered state, thereby making the upper and lower water storage spaces The state between the two ends of the cylinder 1 changes from a connected state to a separated state. It is worth noting that at this time, the water storage space on the lower side is in a closed state. Then, hold the handle 104 on the upper side and pull the sleeve 103 and the connecting column 105 upward, thereby driving the connecting frame, the first rubber plate 108 and the second rubber plate 109 to move upward, so that negative pressure is generated in the cylinder body 1, so that the stream water passes through the one-way valve on the water inlet pipe 101 under the action of negative pressure, and then enters the water storage space on the lower side along the water inlet pipe 101, thereby realizing the extraction of stream water.

[0036] Subsequently, after the stream water fills the water storage space on the lower side, the user presses down the connecting column 105, causing the connecting frame, the first rubber plate 108 and the second rubber plate 109 to move downward. Due to the presence of the one-way valve on the water inlet pipe 101, the stream water in the cylinder body 1 cannot pass through the one-way valve on the water inlet pipe 101. Therefore, the pressure in the water storage space will increase, causing the stream water in the water storage space to be squeezed toward the filter element 2, and after being filtered by the filter element 2, it enters the inner side of the filter element 2, and then moves upward under the action of pressure, and finally flows along the second water outlet pipe 111 and the first connecting pipe 3 to the second connecting pipe 4, and then enters the first water outlet pipe 102, and finally flows out from the other end of the first water outlet pipe 102 into the water bottle, thereby filtering the stream water and obtaining filtered stream water.

[0037] Furthermore, if there is too much sediment in the stream water, resulting in too much sediment being pumped into the water storage space and the water inlet pipe 101, the water inlet pipe 101 is easily blocked by the sediment. At the same time, too many impurities adhering to the outer surface of the filter element 2 will also reduce the filtering effect of the filter element 2. Therefore, after using the filter element 2 located on the lower side to filter the stream water for a period of time, the user takes out the water inlet pipe 101 from the stream water and removes the filter head on the water inlet pipe 101, so that the one-way valve on the water inlet pipe 101 is separated from the water inlet pipe 101, and then rotates the connecting column 105 back to the initial position, so that the connecting frame and the first rubber plate 108 are rotated back to the initial position, so that the first through groove 10801 and the second through groove 10901 on the upper side are restored from the dislocated state to the connected state, and then the cylinder body 1 is placed horizontally as a whole, so that the two filter elements 2 are changed from vertical to horizontal, as shown in FIG. Figure 8As shown, the water inlet pipe 101 and the filter element 2 originally located at the lower side are moved to the front side, and the water inlet pipe 101 and the filter element 2 originally located at the upper side are moved to the rear side. The following perspective is converted from the vertical barrel body 1 to the horizontal barrel body 1. The user puts the water inlet pipe 101 located at the rear side into the water, then holds the handrail 201 with his hand and pulls the handrail 201 upward, so that the connecting tube 202, the first connecting tube 3 and the second connecting tube 4 move upward, thereby deforming the first connecting tube 3 and the second connecting tube 4, and separating from the second water outlet pipe 111 and the first water outlet pipe 102 respectively, thereby exposing the connecting groove 11002, as shown in FIG. Figure 4 As shown, the two second water outlet pipes 111 and the first water outlet pipe 102 are connected through the connecting groove 11002.

[0038] Then, the user holds the connecting post 105 on the front side with his hand, and rotates the connecting post 105 clockwise 90 degrees based on the view from the front to the back, thereby driving the connecting frame and the first rubber plate 108 to rotate clockwise 90 degrees, so that the first through groove 10801 and the second through groove 10901 on the front side change from being connected to being dislocated. At this time, the second through groove 10901 remains connected to the third through groove 11001, and the filter element 2 with mud and sand adhering to the surface is located at the front side. Then, the user holds the handle 104 on the front side, The sleeve 103, the handle 104 and the connecting column 105 are pulled forward, thereby driving the connecting frame and the first rubber plate 108 to move forward, so that the water storage space at the rear side generates negative pressure, so that the stream water enters the water storage space at the rear side. After the water storage space at the rear side is filled with stream water, the user presses the connecting column 105 backward, so that the stream water in the water storage space at the rear side moves toward the filter element 2 under the action of pressure, and enters the filter element 2 after being filtered by the filter element 2, and then flows forward to the second water outlet pipe 111 under the action of pressure, and is discharged from the second outlet pipe 111. The water outlet pipe 111 flows out to the connecting groove 11002, so that the filtered stream water flows from the connecting groove 11002 to the first water outlet pipe 102 and the second water outlet pipe 111 located at the front side, so that a part of the filtered stream water flows out from the first water outlet pipe 102 to the water bottle, and the other part of the filtered stream water flows into the filter element 2 located at the front side along the second water outlet pipe 111 located at the front side, and then flows out from the side of the filter element 2 to the outside of the filter element 2 under the action of the above pressure, realizing the backwashing of the filter element 2 located at the front side, thereby cleaning the filter element 2. The silt on the outside is washed down to prevent a large amount of silt from adhering to the outside of the filter element 2, which causes the filter holes on the filter element 2 to be blocked by silt, affecting the filtering effect of the filter element 2. Subsequently, the mixture of the silt washed down and the water flowing out of the filter element 2 will flow into the water inlet pipe 101, and drive the silt in the water inlet pipe 101 to flow along the water inlet pipe 101, and then flow out to the outside of the water inlet pipe 101, thereby achieving the flushing of the silt adhering to the inside of the water inlet pipe 101, avoiding the inner wall of the water inlet pipe 101 from being adhered to silt, which is difficult to clean and affects the water quality of the stream.

[0039] Finally, after filling the water bottle with filtered stream water, the user restores all components to their pre-use state and places the water purifier into a backpack for storage.

[0040] Each connecting column 105 is provided with a winding portion 10501; when the water purifier is not in use, the user winds the water inlet pipe 101 around the winding portion 10501 to store the water inlet pipe 101, making it easier to store the water purifier.

[0041] Each connecting column 105 is provided with a plurality of semicircular grooves 10502 ; the semicircular grooves 10502 increase the roughness of the surface of the connecting column 105 , thereby increasing the friction on the surface of the connecting column 105 , thereby preventing the user from slipping when rotating the connecting column 105 , which would affect the use effect of the connecting column 105 .

[0042] Example 2

[0043] On the basis of Example 1, Figure 3-Figure 8 As shown, it also includes an air bag 301 and an air inlet pipe 302; two air bags 301 are fixedly connected to the fixing block 110, which are symmetrical in vertical direction; the two air bags 301 are fixedly connected to the adjacent second rubber plate 109; the two air bags 301 are connected to the air inlet pipe 302; a waterproof and breathable membrane is provided on the air inlet pipe 302; the other end of the air inlet pipe 302 is connected to the connecting groove 11002; the following perspective is converted from the vertical barrel 1 to the horizontal barrel 1, as shown Figure 8 As shown, when backwashing the filter element 2, the user pulls the connecting column 105 forward, thereby driving the connecting frame, the first rubber plate 108 and the second rubber plate 109 to move forward, and then stretching the airbag 301 located on the rear side to inflate the inside of the airbag 301. Subsequently, when the user moves the connecting column 105 backward to pressurize the water storage space, the connecting frame, the first rubber plate 108 and the second rubber plate 109 will also move backward, so that the airbag 301 is compressed, so that the gas in the airbag 301 passes through the waterproof and breathable membrane on the air inlet pipe 302 along the air inlet pipe 302, and then enters the connecting groove 11002, and then enters the inside of the filter element 2 along the second water outlet pipe 111, thereby pressurizing the inside of the filter element 2 through the airflow, making it easier for the filtered stream water flowing into the filter element 2 to flow out to the outside of the filter element 2, thereby improving the backwashing effect of the filtered stream water on the filter element 2.

[0044] It also includes a rubber strip 401; several rubber strips 401 are fixedly connected to the left side of the barrel 1; they are used to increase the roughness of the surface of the barrel 1, thereby increasing the friction of the surface of the barrel 1, avoiding slipping when the user holds the barrel 1, and improving the use effect of the barrel 1.

[0045] It also includes a limiter 501; the damping sliding connection on the front side of the cylinder body 1 is connected to the limiter 501; after the user pulls the armrest 201 upwards, the limiter 501 is pressed forward to move the limiter 501 forward, so that the groove on the limiter 501 is embedded in the round rod on the armrest 201, thereby limiting the armrest 201 through the limiter 501 to prevent the armrest 201 from falling downward, causing the connecting cylinder 202 to be re-embedded in the connecting groove 11002, so that the filtered stream water cannot enter the filter element 2 that needs to be cleaned, affecting the backwashing of the filter element 2.

[0046] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.
