DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0031] like Figure 1-4 As shown, a quick disassembly and assembly water purifier includes: a waterway plate 1, a first adapter 2, a second adapter 21, a pre-filter element 3 and an RO filter element 31. In this embodiment, the pre-filter element 3 adopts a composite filter element, that is, a composite filter element that concentrates PP cotton and activated carbon filter materials. Of course, a multiple filter element mode can also be adopted, that is, each pre-filter element is made of a single filter material, such as an activated carbon filter element or a PP cotton filter element.

[0032] As is common knowledge in the art, it is well known that the pre-filter element 3 only has a water inlet and a water outlet, and the RO filter element 31 has a water inlet, a pure water outlet and a waste water outlet.

[0033] A pre-filter element connection port 6 and a RO filter element connection port 7 are sequentially arranged on the peripheral side wall of the waterway plate 1 along the water inlet direction.

[0034] The pre-filter connection port 6 has a water inlet and a clean water outlet, and the RO filter connection port 7 has a clean water inlet, a waste water outlet and a pure water outlet, wherein the clean water outlet of the pre-filter connection port 6 is connected to the clean water inlet of the RO filter connection port 7.

[0035] The waterway plate 1 has a tap water inlet pipe 11 connected to the water inlet of the pre-filter connection port, a clean water outlet pipe 12 connected to the clean water outlet of the pre-filter connection port, a waste water outlet pipe 14 connected to the waste water outlet of the RO filter connection port, and a pure water outlet pipe 13 connected to the pure water outlet of the RO filter connection port.

[0036] The first adapter 2 and the second adapter 21 are both right-angle elbows. The top of the pre-filter element 3 is fixedly connected to one end of the first adapter 2, and the first adapter 2 has a pipeline adapted to the pre-filter element 2. The top of the RO filter element 31 is fixedly connected to one end of the second adapter 21, and the second adapter 21 has a pipeline adapted to the RO filter element 31.

[0037] The other end of the first adapter 2 is plugged into the pre-filter connection port 6, and the other end of the second adapter 21 is plugged into the RO filter connection port 7. In order to ensure the water tightness of the connection when the adapter is plugged into the waterway plate, a sealing ring 61 is provided in the jacks of the pre-filter connection port 6 and the RO filter connection port 7. In order to prevent the sealing ring from being separated from the jack, an annular sleeve 62 is also provided at the entrance of the jack to fasten the sealing ring in the jack, and the adapter is inserted into the annular sleeve 62.

[0038] It should be noted that when a single filter element is used, that is, when the number of pre-filter element connection ports is multiple, the tap water inlet pipe is only connected to the water inlet of the pre-filter element connection port located at the head end of the water inlet direction, and the water inlets of the remaining adjacent pre-filter element connection ports and the pure water outlets are connected in sequence. The connection of this waterway is a well-known technology in the art and will not be described in detail in this application.

[0039] In this embodiment, a water inlet electromagnetic valve 17 and a water inlet TDS sensor 16 are provided at the clean water inlet of the RO filter element connection port 7. Of course, when the clean water flows into the RO filter element, a high-pressure pump is also configured to press the clean water into the RO filter element.

[0040] In this embodiment, a water outlet TDS sensor 15 is provided at the pure water outlet of the RO filter element connection port 7 .

[0041] In this embodiment, a one-way valve 63 and a high-pressure switch 19 are also provided at the pure water outlet of the RO filter element connection port 7 to prevent the pure water from flowing back to the RO filter element.

[0042] In this embodiment, a wastewater solenoid valve 18 is provided at the wastewater outlet of the RO filter element connection port 7 .

[0043] In order to ensure that the adapter does not separate from the waterway plate without external force when the adapter is plugged into the waterway plate, and to achieve rapid assembly and disassembly of the filter element, the device further includes a hook 4 and a block 5.

[0044] like Figure 5 As shown, the hook 4 includes a pressing portion 41, a first wing 43 and a second wing 44 fixedly connected to the two ends of the pressing portion 41, and the actual buckle is in a C shape; the middle parts of the first wing 43 and the second wing 44 are respectively hinged on the top peripheral side wall of the adapter, and the two opposite sides of the top peripheral side wall of the adapter are respectively provided with a convex pin, so that the middle parts of the first wing 43 and the second wing 44 are respectively hinged on the convex pin.

[0045] The upper sides of the ends of the first wing 43 and the second wing 44 are provided with a bayonet 45 of the same shape; the bayonet 45 is arranged adjacent to the connection port.

[0046] The block 5 is fixedly connected to the top of the waterway plate 1 , and the block 5 has a front side surface 51 and a rear side surface 52 .

[0047] The pressing portion 41 is pressed down from top to bottom, the first wing 43 and the second wing 44 rotate with their hinges as the center, the bayonet 45 moves upward, and the bottom of the block 5 is embedded in the bayonet 45. At the same time, the pressing portion 41 surrounds the top peripheral side wall of the adapter to prevent the first adapter or the second adapter from moving away from the waterway plate 1 along the axial direction of the pre-filter element connection port or the RO filter element connection port.

[0048] The bayonet 45 includes a bottom surface and a first side wall and a second side wall connected at both ends of the bottom surface, the first side wall is adjacent to the front side 51 of the card block, and the second side wall is adjacent to the rear side 52 of the card block. The width of the bayonet 45 is slightly greater than the thickness of the card block 5.

[0049] When the adapter is plugged into the connection port, the entrance of the bayonet 45 is adjacent to the bottom side of the clamping block 5 .

[0050] The first side wall has an inclined surface 46 on its upper portion, so that when the pressing portion 41 is pressed down, the edge of the bottom of the front side of the clamping block slides into the clamping hole 45 along the inclined surface 46 until the bottom of the clamping block 5 is embedded in the clamping hole 45 .

[0051] The first side wall has a vertical surface at the bottom, and a first protrusion 47 at the top of the vertical surface. Figure 7 As shown, when the pressing portion 41 is pressed down, the first protrusion 47 is pressed against the front side surface 51 of the block and squeezes the front side surface 51, forcing the end of the adapter to be more deeply inserted into the pre-filter element connection port or the RO filter element connection port. The cooperation between the first protrusion 47 and the front side surface 51 of the block plays a boosting role, which makes the adapter and the waterway plate 1 closer and the waterway connection tighter.

[0052] The first protrusion 47 forms a notch 48 at the lower part of the vertical surface, and the bottom of the front side wall 51 of the clamping block has a second protrusion 53, so that when the bottom of the clamping block 5 is inserted into the clamping hole 45, the second protrusion 53 is inserted into the notch 48. The cooperation of the notch 48 and the second protrusion 53 constitutes a function of preventing the clamping hole 45 from being separated from the clamping block 5 without external force.

[0053] The upper portion of the second side wall has a third protrusion 49, such as Figure 6 As shown, when the pressing portion 41 is lifted, the third protrusion 49 is pressed against the rear side of the block and squeezes the rear side 52, forcing the adapter to move away from the pre-filter connection port or the RO filter connection port.

[0054] In this embodiment, the top of the pressing portion 41 has an extended pressing brim 42 to facilitate pressing or lifting the pressing portion.

[0055] When replacing the filter element, you only need to lift the pressing part and the bayonet will disengage from the block. The bayonet will help the adapter to move away from the waterway plate. At this time, you only need to remove the filter element from the waterway plate, and insert the new filter element with the end of its adapter aligned with the pre-filter element connection port or the RO filter element connection port of the waterway plate. Press down the pressing part, and the bottom of the block will be embedded in the bayonet. At the same time, the first convex part will stick to the front side of the block and squeeze the front side, forcing the port of the adapter to be inserted deeper into the connection port.

[0056] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
