Description

Technical Field

[0001] This invention belongs to the field of water purifiers, specifically a water purifier and its usage method. Background Technology

[0002] A water purifier is a household appliance used to purify water. Through multiple layers of filters, such as PP cotton, activated carbon, and RO reverse osmosis membranes, it effectively removes impurities, odors, heavy metals, bacteria, viruses, and other harmful substances from the water, providing families with healthy and safe drinking water. It is easy to operate; simply connect it to the water pipe for automatic filtration.

[0003] Although water purifiers can filter automatically, the filter cartridges inside can become clogged over time, requiring replacement and flushing. The filter cartridges are typically housed inside the purifier's casing. To flush, the water valve is turned off, and the casing needs to be disassembled to remove the cartridge. During this process, the filter cartridge has openings at both ends, meaning water is still flowing inside, potentially causing significant water splashing and making cleaning difficult and troublesome. Summary of the Invention

[0004] This invention provides a water purifier and its usage method, solving the problem of filter clogging in related technologies. This necessitates filter replacement and flushing, as the filter is typically housed within the purifier's casing. During flushing, the water valve is closed, and the casing needs to be disassembled to remove the filter. However, since both ends of the filter are open, water still flows inside when it is removed, potentially leading to excessive water splashing and making cleaning difficult.

[0005] The first aspect of this invention discloses a water purifier, including a housing. First fixing plates are respectively disposed at the top and bottom of the housing. A hole is formed at the top of the upper first fixing plate, and a screw cap is threaded onto it. A water inlet is slidably installed inside the screw cap and connected to a water valve. Multiple filter elements are disposed inside the housing and connected to the water inlet. A purified water outlet is disposed on the side of the lower first fixing plate and connected to the lower part of the filter elements. A clamping device is disposed inside the screw cap, and a sealing device is disposed on the clamping device. The clamping device is used to clamp the filter element when it is replaced, and the sealing device is used to seal the top of the filter element when it is removed. The clamping device includes a second connecting rod and a clamping block. The clamping block is fixedly installed at the bottom end of the second connecting rod. The second connecting rod and the clamping block are symmetrically installed about the center of the screw cap. A sealing device is rotatably connected to the second connecting rod.

[0006] The sealing device includes a third connecting rod and a sealing block. The sealing block is fixedly installed at the end of the third connecting rod, and the two third connecting rods are close to each other to seal the top of the filter element.

[0007] As a further optimization of the present invention, the clamping device includes a rotating block rotatably mounted on the lower part of the cap, a first connecting rod rotatably mounted on the bottom of the rotating block, a second connecting rod rotatably mounted inside the first connecting rod, a first protrusion fixedly mounted on the side of the first connecting rod, and a first tooth fixedly mounted on the top of the second connecting rod. The first protrusion and the first tooth are connected to the sealing device to drive the sealing block to seal the top of the filter element.

[0008] As a further optimization of the present invention, the sealing device includes a third connecting rod rotatably installed inside the second connecting rod, and the third connecting rod is provided with a second tooth on its exterior.

[0009] As a further optimization of the present invention, the sealing device includes a first fixing block symmetrically arranged on both sides of the first connecting rod, a circular extrusion block is slidably installed inside the first fixing block, a first spring is provided on the outer wall of the circular extrusion block, a first rack is fixedly installed at the end of the circular extrusion block, a first gear is rotatably installed inside the first protrusion, a first gear connecting tooth is fixedly installed on the first gear, and the first gear connecting tooth meshes with the first rack.

[0010] As a further optimization of the present invention, the sealing device includes a second rack disposed on the side wall of the first connecting rod away from the end of the first rack, a second gear is rotatably mounted inside the first gear, a second gear connecting tooth is fixedly mounted on the second gear, and the second gear connecting tooth meshes with the second rack.

[0011] As a further optimization of the present invention, the second gear, the second gear connecting teeth, the first gear, and the first gear connecting teeth are always concentric.

[0012] As a further optimization of the present invention, the sealing block is shaped like a bottle cap, and the material of the sealing block is rubber.

[0013] As a further optimization of the present invention, the first gear meshes with the second gear, the second gear meshes with the first gear, and the circular extrusion block moves to drive the sealing block and the clamping block closer to or further away from each other.

[0014] As a further optimization of the present invention, the minimum distance between the circular extrusion blocks on the two first connecting rods is less than the diameter of the filter element, and the maximum distance between the circular extrusion blocks on the two first connecting rods is greater than the diameter of the filter element.

[0015] A second aspect of this invention discloses a method of using a water purifier, comprising the following steps:

[0016] Step 1: Close the water valve, disconnect the water pipe from the water inlet, then remove the housing from its installation position, and pull the water inlet upwards a certain distance without removing the water inlet from inside the cap.

[0017] Step 2: The sidewall of the circular extrusion block is in contact with the interior of the filter element. Rotate the first connecting rod, which drives the clamping device and sealing device to rise, so that the circular extrusion blocks on the two first connecting rods move closer to each other, causing the first tooth and the second tooth to rotate. The rotation of the first tooth and the second tooth causes the sealing block and the clamping block to move closer to each other, thereby clamping the filter element and sealing the top of the filter element.

[0018] Step 3: Hold the cap and remove the filter element from the inside of the housing to prevent water from flowing out. Move the circular pressing blocks on the two first connecting rods away from each other to remove the filter element from the cap. Then clean it. After cleaning, reinstall it to complete the cleaning process.

[0019] The beneficial effects of this invention are as follows:

[0020] The water purifier and its usage method described in this invention involve rotating the second connecting rod inside the clamping device, which causes two clamping blocks to move closer together, thereby clamping the filter element and facilitating its removal from the housing. Subsequently, the circular pressing block inside the sealing device moves, causing the first and second gears to rotate, which in turn causes the two sealing blocks to move closer together, sealing the top of the filter element and preventing leakage and cleaning difficulties during replacement.

[0032] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0033] like Figures 1 to 6As shown in the figure, a water purifier according to an embodiment of the present invention includes a housing 1. First fixing plates 11 are respectively provided at the top and bottom of the housing 1. A hole is opened at the top of the upper first fixing plate 11, and a screw cap 12 is threadedly installed thereon. A water inlet 13 is slidably installed inside the screw cap 12, and the water inlet 13 is connected to a water valve. Multiple filter elements 15 are provided inside the housing 1, and the filter elements 15 are connected to the water inlet 13. A purified water outlet 14 is provided on the side of the lower first fixing plate 11, and the purified water outlet 14 is connected to the lower part of the filter elements 15. A clamping device 2 is provided inside the screw cap 12, and a sealing device 3 is provided on the clamping device 2. The clamping device 2 is used to hold the filter element 15 when it is replaced, and the sealing device 3 is used to seal the top of the filter element 15 when it is removed. The clamping device 2 includes a second connecting rod 23 and a clamping block 24. The clamping block 24 is fixedly installed at the bottom end of the second connecting rod 23. The second connecting rod 23 and the clamping block 24 are symmetrically installed about the center of the screw cap 12. 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. The sealing block 36 is fixedly installed at the end of the third connecting rod 31. The two third connecting rods 31 are close to each other to seal the top of the filter element 15.

[0034] It should be noted that when cleaning the filter element 15, first close the water valve, then pull the water inlet 13 upwards, without completely pulling the water inlet 13 into the inside of the cap 12. Then, rotate the cap 12 to make the cap 12 rise. When the cap 12 rises, the sealing devices 3 installed symmetrically on the cap 12 will move closer to each other, which will 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 move closer to each other, thereby clamping the filter element 15 and sealing the opening at the top of the filter element 15. The filter element 15 has two openings. When one of the openings is sealed, the inside of the filter element 15 is subjected to atmospheric pressure, which prevents water from flowing out from the bottom. This prevents a large amount of water and sewage from flowing out of the filter element 15 during replacement or cleaning, which would cause cleaning and treatment problems.

[0035] like Figures 4 to 6 As shown, the clamping device 2 includes a rotating block 21 rotatably mounted on the lower part of the cap 12. A first connecting rod 22 is rotatably mounted on the bottom of the rotating block 21. The interior of the first connecting rod 22 is rotatably mounted with a 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.

[0036] 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 mesh with the second tooth 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 or further away from each other, thereby clamping the filter element 15.

[0037] like Figure 6 As shown, the sealing device 3 includes a third connecting rod 31 rotatably installed inside the second connecting rod 23, and the third connecting rod 31 is provided with a second tooth 311 on its outside.

[0038] It should be noted that when it is necessary to rotate the third connecting rod 31, a motor can be used to mesh with the second tooth 311 to rotate the third connecting rod 31, so that the sealing blocks 36 on the third connecting rod 31 move closer or further apart.

[0039] like Figure 6 As shown, the sealing device 3 includes a first fixing block 32 symmetrically arranged on both sides of the first connecting rod 22. A circular pressing block 33 is slidably installed inside the first fixing block 32. A first spring 34 is provided on the outer wall of the circular pressing block 33. A first rack 35 is fixedly installed at the end of the circular pressing block 33. A first gear 37 is rotatably installed inside the first protrusion 221. A first gear connecting tooth 371 is fixedly installed on the first gear 37. The first gear connecting tooth 371 meshes with the first rack 35.

[0040] It should be noted that when the third connecting rod 31 needs to be rotated, a circular pressing block 33 and a first rack 35 are provided on the side of the first connecting rod 22. When the cap 12 rises, the circular pressing block 33 and the first rack 35 slide outside the filter element 15, and the two ends of the filter element 15 are in a contracted state. Therefore, the circular pressing blocks 33, which are symmetrically installed with respect to the cap 12, can move closer to each other, thereby driving the first rack 35 to move. The first rack 35 meshes 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.

[0041] like Figure 7 As shown, the sealing device 3 includes a second rack 39 disposed 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 mounted inside the first gear 37. A second gear connecting tooth 381 is fixedly mounted on the second gear 38. The second gear connecting tooth 381 meshes with the second rack 39.

[0042] It should be noted that when the second connecting rod 23 needs to be rotated, a second rack 39, identical to the circular pressing block 33, the first spring 34, and the first rack 35, is provided on the side of the first connecting rod 22. The second rack 39 meshes with the lower part of the second gear connecting tooth 381, while the first rack 35 meshes with the upper part of the first gear connecting tooth 371. This causes the first gear connecting tooth 31 and the second connecting rod 23 to rotate in opposite directions. Consequently, the third connecting rod 31 and the second connecting rod 23 move closer to each other, thereby causing the sealing block 36 and the clamping block 24 to clamp and seal the filter element 15.

[0043] like Figure 7 As shown, the second gear 38, the second gear connecting tooth 381, the first gear 37, and the first gear connecting tooth 371 are always concentric.

[0044] It should be noted that the second gear 38, the second gear connecting tooth 381, the first gear 37, and the first gear connecting tooth 371 are always concentric, which provides good stability during rotation.

[0045] like Figure 5 As shown, the sealing block 36 is shaped like a bottle cap, and the material of the sealing block 36 is rubber.

[0046] It should be noted that the sealing block 36 is shaped like a bottle cap and is made of rubber, so that the sealing block 36 can contact the top of the filter element 15 and seal it.

[0047] like Figure 7 As shown, the first gear 37 meshes with the second tooth 311, the second gear 38 meshes with the first tooth 231, and the circular pressing block 33 moves to drive the sealing block 36 and the clamping block 24 to move closer or further apart from each other.

[0048] like Figures 4 to 6 As shown, the minimum distance between the circular extrusion blocks 33 on the two first connecting rods 22 is less 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 greater than the diameter of the filter element 15.

[0049] It should be noted that the minimum distance between the circular pressing blocks 33 on the two first connecting rods 22 is less than the diameter of the filter element 15, and the maximum distance between the circular pressing blocks 33 on the two first connecting rods 22 is greater than the diameter of the filter element 15, so that when the cap 12 moves up and down on the first fixed plate 11, it can drive the circular pressing blocks 33 to move closer to or away from the center of the filter element 15.

[0050] A method of using a water purifier, the method employing the aforementioned water purifier, includes the following steps:

[0051] Step 1: Close the water valve, disconnect the water pipe from the water inlet 13, then remove the housing 1 from its installation position, and pull the water inlet 13 upwards a certain distance without removing the water inlet 13 from the inside of the cap 12.

[0052] Step 2: The sidewall of the circular extrusion block 33 is in contact with the interior of the filter element 15. Rotate the first connecting rod 22. 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 move closer to each other, causing the first tooth 231 and the second tooth 311 to rotate. The rotation of the first tooth 231 and the second tooth 311 causes the sealing block 36 and the clamping block 24 to move closer to each other, thereby clamping the filter element 15 and sealing the top of the filter element 15.

[0053] Step 3: Hold the cap 12 and remove the filter element 15 from the inside of the housing 1 to prevent water from flowing out of the filter element 15. Move the circular pressing blocks 33 on the two first connecting rods 22 away from each other, and then remove the filter element 15 from the cap 12. After cleaning, install it to complete the cleaning work.

[0054] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
