[0003] When using a portable water purifier outdoors, there is a large amount of sediment in the stream water.

[0021] 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 symmetrically connected to the cylinder body 1 are sleeved; two handles 104 symmetrically connected to each sleeve 103; two sleeves 103 are rotatably connected to the opposite sides of each other with a connecting column 105; 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.

[0022] 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; a first rubber plate 108 is fixedly connected to one end of all the connecting frames located on the same connecting column 105 close to the middle of the barrel 1; a first through groove 10801 is provided on each first rubber plate 108; a second rubber plate 109 is fixedly connected to the side of each first rubber plate 108 close to the fixed block 110; a second through groove 10901 is provided on each second rubber plate 109; each second through groove 10901 is communicated with the adjacent first through groove 10801; a third through groove 11001 is provided on the fixed block 110; each third through groove 11001 is communicated with the second through groove 10901.

[0023] 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 fixedly connected 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.

[0024] First, the sleeve 103 located on the upper side is used for explanation. The user puts the water inlet pipe 101 located on the lower side into the stream water, and then holds the middle part of the barrel body 1 with one hand, and holds the connecting column 105 located on the upper side with the other hand, and rotates the connecting column 105 clockwise by 90 degrees based on the view from top to bottom, thereby driving the connecting frame and the first rubber plate 108 to rotate clockwise by 90 degrees, so that the first through groove 10801 and the second through groove 10901 are changed from the initial connected state to the dislocated state, thereby making the upper and lower water storage spaces The state of the water storage space at the lower side is changed from a connected state to a separated state. It is worth noting that at this time, the water storage space at the lower side is in a closed state. Then, the handle 104 at the upper side is held to 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 at the lower side along the water inlet pipe 101, thereby realizing the extraction of stream water.

[0025] Subsequently, after the stream water fills the water storage space on the lower side, the user presses downward on the connecting column 105, so that the connecting frame, the first rubber plate 108 and the second rubber plate 109 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, so that the stream water in the water storage space is squeezed toward the filter element 2, and enters the inner side of the filter element 2 after being filtered by 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.

[0026] 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 adhered 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 connecting column 105 located on the lower side is used to illustrate that the user takes the water inlet pipe 101 out of 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 located 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, and the lower viewing angle is changed 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, and 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, so that the first connecting tube 3 and the second connecting tube 4 are deformed and separated 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.

[0027] Then, the user holds the connection column 105 on the front side with his hand, and rotates the connection column 105 90 degrees clockwise based on the view from the front to the back, thereby driving the connection 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 on the front side change from a connected state to a dislocated state. At this time, the second through groove 10901 and the third through groove 11001 remain connected, and the filter element 2 with mud and sand adhered 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 flows out from the second 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, respectively, 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 above-mentioned pressure, so as to realize 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 may cause the filter holes on the filter element 2 to be blocked by silt and affect 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 flushing the silt adhering to the inside of the water inlet pipe 101, and preventing 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.

[0028] 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.

[0029] 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, which is convenient for storing the water purifier.

[0030] A plurality of semicircular grooves 10502 are formed on each connecting column 105 ; 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 of the connecting column 105 .

[0031] Example 2 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 height; the two air bags 301 are fixedly connected to the adjacent second rubber plates 109, respectively; 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 in FIG. Figure 8 As shown, when backwashing the filter element 2, the user pulls the connecting column 105 to move 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 inner side of the filter element 2 along the second water outlet pipe 111, so that the inner side of the filter element 2 is pressurized by the airflow, so that the filtered stream water flowing into the filter element 2 is easier 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.

[0032] It also includes a rubber strip 401; a plurality of 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.

[0033] 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.

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 also fall within the scope limited by the appended claims of the application.
