A filter chamber 3 is provided on the outer side of the negative pressure chamber 2, and the filter chamber 3 can allow the water source squeezed out from the inner side of the negative pressure chamber to pass through the inner side thereof for filtration. A clean water storage chamber 4 is provided on the upper part of the filter chamber 3, and the clean water storage chamber 4 is connected with the inner side of the filter chamber 3, and can store the clean water filtered by the filter chamber 3 inside thereof.

[0027] A filter assembly 5 is slidingly connected inside the filter bin 3, and the filter assembly 5 can filter and sterilize the water source flowing out of the negative pressure chamber 2. An outlet pipe 6 is connected to the upper part of the outer wall of the side of the water purification cylinder 1, and the outlet pipe 6 is connected to the inside of the clean water storage bin 4. The clean water inside the clean water storage bin 4 will be discharged through the outlet pipe 6 under the pressure inside the negative pressure chamber 2.

[0028] It should be noted that the filter component 5 can be selected from one of an ultrafiltration membrane filter element and an ultrafiltration membrane and carbon fiber composite filter element, and the filter component 5 can preferably be an ultrafiltration membrane.

[0029] A negative pressure plug rod 7 is passed through the negative pressure chamber 2. One end of the negative pressure plug rod 7 located inside the negative pressure chamber 2 is sealed, fitted and slidably connected to the inner wall of the negative pressure chamber 2. By pulling the negative pressure plug rod 7, suction and pressure can be provided for the inner side of the negative pressure chamber 2, so that the water source sucked into the negative pressure chamber 2 enters the inner side of the filter assembly 5 under the pressure generated by pushing the negative pressure plug rod 7, and is filtered through the filter assembly 5. Then, the filtered clean water is squeezed into the inner side of the clean water storage tank 4 and discharged outward.

[0030] A base 8 is threadedly screwed onto the bottom surface of the water purification cartridge 1. A sealing ring is provided at the connection position between the base 8 and the water purification cartridge 1 to seal the bottom surface of the water purification cartridge 1. The design of the base 8 allows the bottom of the water purification cartridge 1 to be disassembled, which facilitates the cleaning of the inside of the water purification cartridge 1 and allows the filter assembly 5 inside the water purification cartridge 1 to be taken out and replaced.

[0031] A water suction hole 9 is opened at the center of the bottom surface of the base 8, and the water suction hole 9 is connected to the inside of the water purification cylinder 1. When the negative pressure plug rod 7 inside the negative pressure chamber 2 is pulled, the negative pressure generated inside the water purification cylinder 1 will draw external water through the water suction hole 9.

[0032] It should be noted that: one end of the water absorption hole 9 located inside the water purification cylinder 1 is connected to a one-way valve, and water can only enter the water source through the water absorption hole 9 and cannot be discharged from the water source.

[0033] The bottom of the water suction hole 9 is located at one end below the base 8 and is connected to a water suction pipe 10 . The water suction pipe 10 can increase the water suction length of the water suction hole 9 and improve the convenience of use of the water purification cylinder 1 .

[0034] A storage bin 11 is provided on the bottom surface of the base 8 , and the water pumping pipe 10 is rolled into a ring shape and stored inside the storage bin 11 when not in use, which can facilitate the storage of the water pumping pipe 10 and improve the portability of the water purification cylinder 1 .

[0035] The bottom surface of the base 8 is provided with an embedded bottom cover 12, which can protect the water suction pipe 10.

[0036] The inner wall of the filter bin 3 is fixed with equidistantly arranged rubber sealing rings 13, which can increase the sealing performance between the filter assembly 5 and the inner wall of the filter bin 3, thereby preventing the water source inside the negative pressure chamber 2 from flowing to the clean water storage bin 4 through the gap between the filter assembly 5 and the filter bin 3 when under pressure, thereby improving the purification quality of the water source.

[0037] Symmetrical positioning blocks 14 are connected to both sides of the top surface of the base 8 , and the positioning blocks 14 are embedded and connected to the bottom surface of the filter assembly 5 .

[0038] When replacing the filter assembly 5, through the engagement connection between the positioning block 14 and the filter assembly 5, when the base 8 is rotated, the outer wall of the filter assembly 5 and the inner wall of the filter chamber 3 can be spirally advanced, so that the filter assembly 5 and the rubber sealing ring 13 are embedded and fit together, thereby increasing the fit and sealing between the filter assembly 5 and the rubber sealing ring 13.

[0039] A pipe seat 15 is provided at the position where the water purification cylinder 1 is connected to the water outlet pipe 6. A pipe cover 16 is hinged at one end of the pipe seat 15. The pipe cover 16 is sealed and covered on the top surface of the pipe seat 15, and a sealing pipe 17 for placing the water outlet pipe 6 is opened between the pipe seat 15 and the pipe cover 16. Through the sealing pipe 17, the outer wall and the end of the water outlet pipe 6 can be sealed to provide sanitary conditions after use and during storage. The design of the hook 18 at the end of the pipe cover 16 can complete the fixed buckle connection between the pipe seat 15 and the pipe cover 16 after the pipe cover 16 covers the water outlet pipe 6.

[0040] A water suction pump 22 is provided on the bottom surface of the storage bin 11, and the water suction pump 22 is connected to the middle part of the pumping pipe 10, so that when the device is in use, it can absorb and purify outdoor water sources by electric means, thereby improving the convenience of use, and a battery 23 is provided on one side of the water suction pump 22 to provide electric drive for the water suction pump 22.

[0041] A purification seat 19 is provided on one side of the water purification cylinder 1, and a transparent shell 20 is connected to the top surface of the purification seat 19. A purification filter element 21 is provided on the inner side of the transparent shell 20. The setting of the purification seat 19 can, when the device uses a water suction pump 22 to absorb water at a high speed, perform high-quality essence on the water absorption of the water suction pump 22 through double filtration of the internal essence filter element of the purification seat 19 and the activated carbon cartridge, thereby ensuring the quality of purified water when the water suction pump 22 absorbs water at a high speed.

[0042] At the same time, the transparent shell 20 can also observe the status of the essence filter element in real time to facilitate the replacement of the essence filter element and ensure the quality of purified water.

[0043] It should be noted that: both sides of the purification seat 19 are connected to the water pump 10, one end of the water pump 10 is connected to the water suction pump 22, and the water suction pump 22 provides suction to the inside of the purification seat 19, while the other end is used to connect to the water source for pumping water.

[0044] It should be noted that during the operation of the water suction pump 22, the water source drawn in will be sent to the inside of the filter assembly 5, and then filtered into the clean water storage tank 4.

[0045] It should be noted that the storage bin 11 can not only store the water pumping pipe 10, but also place and install the water suction pump 22 and the battery 23. By replacing different water pumping pipes 10, the equipment can be used manually or electrically, and the purification seat 19 can be installed and used according to actual use, thereby improving the portability of the device.

[0046] Usage process:

[0047] Take out the bottom cover 12, connect the water suction pipe 10 to the water suction hole 9, then put the other end of the water suction pipe into the water, repeatedly pull the negative pressure plug rod 7, and the water source can be drawn into the negative pressure chamber 2 inside the water purification cylinder 1. At this time, the air and water source inside the negative pressure chamber 2 will pass through the filter chamber 3 into the clean water storage chamber 4. Then, when the clean water storage chamber 4 is full, the water source will be discharged through the outlet pipe 6 to complete the extraction of clean water.

[0048] After the water purification cartridge 1 has been used for multiple times, the base 8 can be removed and the filter assembly 5 can be replaced to be used for water purification again.

[0049] When the equipment is driven electrically, the button located on the side of the negative pressure plug rod 7 at the top of the water purification cylinder 1 is pressed to start the water suction pump 22. The water suction pump 22 provides suction to the water suction pipe 10, so that the water suction pipe 10 connected to the side of the purification seat 19 can quickly draw the water source into the purification filter element 21 inside the purification seat 19, and then enter the inside of the water purification barrel through the purification filter element 21, and then pass through the activated carbon cartridge to be filtered again, and then discharged to the outside through the water outlet pipe 6 to complete the water purification effect.
