[0018] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0019] like Figures 1 to 6 As shown, a water purifier according to an embodiment of the present invention comprises a housing 1, wherein first fixing plates 11 are respectively arranged at the upper and lower parts of the housing 1, a hole is opened at the top end of the first fixing plate 11 at the upper part, a screw cap 12 is threadedly installed, a water inlet connection port 13 is slidably installed inside the screw cap 12, and the water inlet connection port 13 is connected to a water valve, a plurality of filter elements 15 are arranged inside the housing 1, and the filter elements 15 are connected to the water inlet connection port 13, a clean water outlet 14 is arranged at the side of the first fixing plate 11 at the lower part, and the clean water outlet 14 is connected to the lower part of the filter element 15, a clamping device 2 is arranged inside the screw cap 12, a sealing device 3 is arranged on the clamping device 2, and the clamping device 2 is provided with a sealing device 3. The device 2 is used to clamp the filter element 15 when replacing the filter element 15, and the sealing device 3 is used to seal the top of the filter element 15 when taking out the filter element 15; the clamping device 2 includes a second connecting rod 23 and a clamping block 24, and the clamping block 24 is fixedly installed at the bottom end of the second connecting rod 23, and the second connecting rod 23 and the clamping block 24 are symmetrically installed about the center of the rotary cover 12, and the sealing device 3 is rotatably connected to the second connecting rod 23; the sealing device 3 includes a third connecting rod 31 and a sealing block 36, and the sealing block 36 is fixedly installed at the end of the third connecting rod 31, and the two third connecting rods 31 are close to each other for sealing the top of the filter element 15.

[0020] It should be noted that when the filter element 15 needs to be cleaned, the water valve is closed first, and then the water inlet connection port 13 is pulled out upwards. The water inlet connection port 13 does not need to be completely pulled out to the inside of the rotary cover 12. Then, rotating the rotary cover 12 can drive the rotary cover 12 to rise. The rising of the rotary cover 12 makes the sealing device 3 symmetrically installed on the closed rotary cover 12 approach each other, which can drive the third connecting rod 31 and the second connecting rod 23 to rotate, so that the two sealing blocks 36 and the clamping block 24 approach each other, thereby clamping the filter element 15 and sealing the opening at the top of the filter element 15. There are two openings on the filter element 15. When one of the openings is sealed, the inside of the filter element 15 is affected by atmospheric pressure, so that water will not flow out from the bottom, preventing a large amount of water and sewage from flowing out of the inside of the filter element 15 when replacing or cleaning, causing cleaning and handling problems.

[0021] like Figures 4 to 6 As shown, the clamping device 2 includes a rotating block 21 rotatably mounted at the lower part of the rotating cover 12, a first connecting rod 22 is rotatably mounted at the bottom of the rotating block 21, the interior of the first connecting rod 22 is rotatably mounted with the second connecting rod 23, a first protrusion 221 is fixedly mounted on the side of the first connecting rod 22, a first tooth 231 is fixedly mounted on the top of the second connecting rod 23, the first protrusion 221 and the first tooth 231 are connected to the sealing device 3, and are used to drive the sealing block 36 to seal the top of the filter element 15.

[0022] It should be noted that when it is necessary to drive the two second connecting rods 23 to rotate, a motor can be used to engage with the second teeth 311 to drive the two second connecting rods 23 to rotate, so that the clamping blocks 24 at the ends of the second connecting rods 23 move closer to or farther away from each other, thereby clamping the filter element 15.

[0023] like Figure 6 As shown, the sealing device 3 includes a third connecting rod 31 rotatably mounted inside the second connecting rod 23 , and a second tooth 311 is disposed outside the third connecting rod 31 .

[0024] It should be noted that when the third connecting rod 31 needs to be driven to rotate, a motor can be used to engage with the second teeth 311 to drive the third connecting rod 31 to rotate, so that the sealing blocks 36 on the third connecting rod 31 move closer to or farther from each other.

[0026] It should be noted that when it is necessary to drive the third connecting rod 31 to rotate, a circular extrusion block 33 and a first rack 35 are provided on the side of the first connecting rod 22. When the rotary cover 12 rises, the circular extrusion block 33 and the first rack 35 slide on the outside of the filter element 15, and the two ends of the filter element 15 are in a contracted state. Therefore, the circular extrusion blocks 33 symmetrically installed about the rotary cover 12 can be made close to each other, thereby driving the first rack 35 to move, and the first rack 35 is engaged with the first gear connecting tooth 371, and the first gear connecting tooth 371 is connected to the first gear 37, thereby driving the third connecting rod 31 to rotate.

[0027] like Figure 7 As shown, the sealing device 3 includes a second rack 39 arranged on the side wall of the first connecting rod 22 away from the end of the first rack 35, a second gear 38 is rotatably installed inside the first gear 37, a second gear connecting tooth 381 is fixedly installed on the second gear 38, and the second gear connecting tooth 381 is meshed with the second rack 39.

[0028] It should be noted that when it is necessary to drive the second connecting rod 23 to rotate, a second rack 39 that is identical to the circular extrusion block 33, the first spring 34 and the first rack 35 is provided on the side of the first connecting rod 22, and the second rack 39 is meshed with the lower portion of the second gear connecting tooth 381, while the first rack 35 is meshed with the upper portion of the first gear connecting tooth 371, so that the first gear connecting tooth 31 and the second connecting rod 23 rotate in opposite directions, and the third connecting rod 31 and the second connecting rod 23 approach each other, thereby driving the sealing block 36 and the clamping block 24 to clamp and seal the filter element 15.

[0029] like Figure 7 As shown, the second gear 38, the second gear connecting teeth 381, the first gear 37, and the first gear connecting teeth 371 are always concentric.

[0030] It should be noted that the second gear 38 , the second gear connecting teeth 381 , the first gear 37 , and the first gear connecting teeth 371 are always concentric, which provides better stability during rotation.

[0031] like Figure 5 As shown, the sealing block 36 is in the shape of a bottle cap, and the material of the sealing block 36 is rubber material.

[0032] It should be noted that the sealing block 36 is in the shape of a bottle cap and is made of a rubber material, so that the sealing block 36 can contact the top of the filter element 15 and seal it at the same time.

[0033] like Figure 7 As shown, the first gear 37 is meshed with the second tooth 311 , the second gear 38 is meshed with the first tooth 231 , and the circular extrusion block 33 moves to drive the sealing block 36 and the clamping block 24 to move closer to or away from each other.

[0034] like Figures 4 to 6 As shown, the minimum distance between the circular extrusion blocks 33 on the two first connecting rods 22 is smaller than the diameter of the filter element 15 , and the maximum distance between the circular extrusion blocks 33 on the two first connecting rods 22 is larger than the diameter of the filter element 15 .

[0035] It should be noted that the minimum distance between the circular extrusion blocks 33 on the two first connecting rods 22 is smaller than the diameter of the filter element 15, and the maximum distance between the circular extrusion blocks 33 on the two first connecting rods 22 is larger than the diameter of the filter element 15, so that when the rotary cover 12 is raised or lowered on the first fixed plate 11, the circular extrusion block 33 can be driven to move closer to or away from the center of the filter element 15.

[0036] A method for using a water purifier, the method using the water purifier described above, comprising the following steps: Step 1: Close the water valve, disconnect the water pipe from the water inlet connection port 13, then remove the housing 1 from the installation position, and pull the water inlet connection port 13 upwards for a certain distance without removing the water inlet connection port 13 from the inside of the screw cap 12; Step 2: The side wall of the circular extrusion block 33 is in contact with the interior of the filter element 15, and the first connecting rod 22 is rotated. The first connecting rod 22 drives the clamping device 2 and the sealing device 3 to rise, so that the circular extrusion blocks 33 on the two first connecting rods 22 are close to each other, driving the first teeth 231 and the second teeth 311 to rotate. The first teeth 231 and the second teeth 311 rotate and drive the sealing block 36 and the clamping block 24 to approach each other, thereby clamping the filter element 15 and sealing the top of the filter element 15; Step three, hold the screw cap 12, take out the filter element 15 from the inside of the housing 1, prevent the water inside the filter element 15 from flowing out, move the two circular extrusion blocks 33 on the first connecting rods 22 away from each other, then take out the filter element 15 from the screw cap 12, and then clean it.
