[0003] In view of this, the purpose of this utility model is to provide a water purifier that is easy to clean and convenient to disassemble and install filter cartridges.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A water purifier with an easy-to-clean and easy-to-disassemble filter element includes a cylinder, a cover, and a filter element. The cover is detachably connected to a first end of the cylinder. A partition is provided inside the second end of the cylinder, forming a first receiving cavity between the partition and the cover. A second receiving cavity is formed on the side of the partition away from the first receiving cavity. The filter element is detachably connected to the first receiving cavity, dividing the first receiving cavity into a raw water cavity and a purified water cavity.

[0006] The cylinder is provided with a raw water inlet connected to the raw water chamber and a purified water outlet connected to the second accommodating chamber. The purified water chamber is connected to the purified water outlet through a purified water outlet pipe.

[0007] The filter element has a first through hole connecting the purified water chamber and the raw water chamber, the partition has a second through hole connecting the raw water chamber and the second accommodating chamber, and the purified water outlet pipe extends from the purified water chamber through the first through hole and the second through hole to the second accommodating chamber and is connected to the purified water outlet.

[0008] In the specific embodiment, the filter element includes a filter head and filter membrane fibers. The filter head is detachably connected to the first end of the cylinder. The raw water chamber is formed between the filter head and the partition, and the purified water chamber is formed between the filter head and the cover. The filter membrane fibers are connected to the filter head in the raw water chamber, and the first through hole is opened at the center of the filter head.

[0009] In the specific design, the purified water outlet pipeline includes a first pipe, a second pipe, and a third pipe connected in sequence; the first end of the first pipe is connected to the purified water chamber, and the second end of the first pipe is inserted into the first through hole from the purified water chamber; the first end of the second pipe is inserted into the first through hole from the raw water chamber, and the second end of the second pipe is inserted into the second through hole from the raw water chamber; the first end of the third pipe is inserted into the second through hole from the second accommodating cavity, and the second end of the third pipe is exposed from the cylinder to form the purified water outlet.

[0010] In the specific design, a connector is provided in the second through hole, the second end of the second pipe is inserted into one end of the connector, and the first end of the third pipe is threadedly connected to the other end of the connector.

[0011] In the specific design, an annular groove is provided on the outer wall of the filter head, and a sealing ring is provided in the annular groove, with the sealing ring abutting against the inner wall of the accommodating cavity.

[0027] This utility model embodiment provides a water purifier with an easy-to-clean and easy-to-disassemble filter cartridge. (See attached document.) Figures 1 to 6 The water purifier mainly includes a cylinder 1, a cover 2 and a filter element 3. The cover 2 is detachably connected to the first end of the cylinder 1. A partition 4 is provided inside the second end of the cylinder 1. A first receiving cavity 5 is formed between the partition 4 and the cover 2. A second receiving cavity 6 is formed on the side of the partition 4 away from the first receiving cavity 5.

[0028] The filter element 3 is detachably connected to the first accommodating cavity 5, dividing the first accommodating cavity 5 into a raw water cavity 51 and a purified water cavity 52, with the purified water cavity 52 located above the raw water cavity 51. The cylindrical body 1 is provided with a raw water inlet 11 connecting to the raw water cavity 51 and a purified water outlet 12 connecting to the second accommodating cavity 6. The purified water cavity 52 is connected to the purified water outlet 12 via a purified water outlet pipe 7. Furthermore, the filter element 3 has a first through hole 33 connecting the purified water cavity 52 and the raw water cavity 51, and the partition 4 has a second through hole 41 connecting the raw water cavity 51 and the second accommodating cavity 6. The purified water outlet pipe 7 extends from the purified water cavity 52 through the first through hole 33 and the second through hole 41 to the second accommodating cavity 6 and connects to the purified water outlet 12.

[0029] Specifically, the filter element 3 includes a filter head 31 and filter membrane fibers 32. The filter head 31 is detachably connected to the first end of the cylinder 1. The raw water chamber 51 is formed between the filter head 31 and the partition 4, and the purified water chamber 52 is formed between the filter head 31 and the cover 2. The filter membrane fibers 32 are connected to the filter head 31 within the raw water chamber 51, and the first through hole 33 is located at the center of the filter head 31.

[0030] In this embodiment, the purified water outlet pipe 7 includes a first pipe 71, a second pipe 72, and a third pipe 73 connected in sequence. The first end of the first pipe 71 is connected to the purified water chamber 52, and the second end of the first pipe 71 is inserted into the first through hole 33 from the purified water chamber 52. The first end of the second pipe 72 is inserted into the first through hole 33 from the raw water chamber 51, and the second end of the second pipe 72 is inserted into the second through hole 41 from the raw water chamber 51. The first end of the third pipe 73 is inserted into the second through hole 41 from the second receiving cavity 6, and the second end of the third pipe 73 is exposed on the cylinder 1 to form the purified water outlet 12.

[0031] As described above, in the water purifier, the filter element 3 divides the first accommodating cavity 5 inside the cylinder 1 into a raw water cavity 51 and a purified water cavity 52. ​​In the vertical direction, the purified water cavity 52 and the purified water outlet 12 are located on opposite sides of the raw water cavity 51. After the raw water enters the raw water cavity 51, it is filtered by the filter membrane 32 in the filter element 3 and flows first to the purified water cavity 52 located above. The purified water in the purified water cavity 52 is connected to the purified water outlet 12 located below through the purified water outlet pipe 7 that runs through the raw water cavity 51. Based on this water flow direction, the raw water can make more sufficient contact with the filter membrane 32 in the raw water cavity 51 for filtration, thereby improving the filtration effect.

[0032] As described above, when the filter element 3 needs to be cleaned, the cover 2 is removed from the cylinder 1 and the filter element 3 is taken out. The filter element 3 can be cleaned without removing the outer shell of the water purifier or disconnecting the connecting pipes, which saves time and effort.

[0033] Furthermore, when the filter element 3 is removed from the cylinder 1 for cleaning, the water outlet pipe 7 (the second pipe 72 in the figure) remains connected inside the cylinder 1. The second pipe 72 and the first through hole 33 in the filter element 3 form an alignment and positioning mechanism. When the filter element 3 is reinstalled, the first through hole 33 in the filter element 3 is aligned with the second pipe 72 and then inserted into the cylinder 1. This can prevent the filter element 3 from being misaligned or otherwise poorly assembled, which would affect the filtration effect.

[0034] It should be noted that each part of the purified water outlet pipe 7 is sealed to the first through hole 33 and the second through hole 41, for example, by using sealing rings or sealing gaskets. As a preferred embodiment, in this embodiment, a connector 42 is provided in the second through hole 41, the second end of the second pipe 72 is inserted into one end of the connector 42, and the first end of the third pipe 73 is threaded to the other end of the connector 42.

[0035] In this embodiment, an annular groove 34 is provided on the outer wall of the filter head 31, and a sealing ring 35 is provided in the annular groove 34. The sealing ring 35 abuts against the inner wall of the first receiving cavity 5. By providing the sealing ring 35, the sealing performance of the first receiving cavities 5 on both sides of the filter head 31 can be ensured, so that water flow will not flow through the gap between the filter head 31 and the inner wall of the first receiving cavity 5 and affect the filtration effect.

[0036] In this embodiment, a pressure gauge 8 is connected to the cover 2 for measuring the pressure inside the first accommodating cavity 5, and the pressure inside the cavity can be monitored through the pressure gauge 8.

[0037] In this embodiment, the cylinder 1 and the cover 2 are detachably connected together by a clamp 9, which makes it easy to assemble and disassemble the cylinder 1 and the cover 2, and facilitates the removal of the cover 2 from the cylinder 1, thereby making it easy to remove the filter element 3 from the cylinder 1.

[0038] In this embodiment, the cylinder 1 is also provided with a concentrated water outlet 13 that connects to the raw water chamber 51, wherein the concentrated water outlet 13 is located at one end near the partition 4. By providing the concentrated water outlet 13, in some cases, a high-pressure water flow can be introduced from the raw water inlet 11 to perform self-cleaning on the filter element 3, and the cleaned wastewater is discharged from the concentrated water outlet 13.

[0039] In this embodiment, the purified water outlet 12, the concentrated water outlet 13, and the raw water inlet 11 are located on the same side of the cylinder 1. The purified water outlet 12, the concentrated water outlet 13, and the raw water inlet 11 are arranged sequentially from bottom to top on the cylinder 1 and are located on the same straight line, which makes it easier to connect to external pipelines and reduces the space occupied by the water purifier.

[0040] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
