[0002] Water purifiers have become a must-have device for every household. Water purifiers usually include a waterway board and a filter element. The waterway board is used to connect the inlet and outlet water pipes and the filter element. Water purifiers, especially those located in the kitchen, have their filter elements mostly installed under the sink. The space under the sink is usually narrow and the installation space is limited. In order to be able to quickly and conveniently remove the filter element in the narrow space, an adapter is usually connected to the filter element. The adapter is usually a right-angle elbow, so that the filter element can be inserted into the connecting port of the waterway board in a horizontal straight manner to achieve the connection between the waterway board and the filter element. Usually, a quick-connect plug is used to connect the waterway board and the filter element. The filter element is a consumable item and is often replaced, but the waterway board needs to be used for a long time. Therefore, the quick-connect plug is prone to aging and brittleness under long-term use. Moreover, under the impact of long-term water flow pressure, the connection between the waterway board and the adapter is prone to loosening and leakage. Summary of the invention

DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 1-2 As shown, a water purifier filter element quick fixing connection structure, the water purifier includes a waterway plate 1, a filter element 3 and an adapter 2, the adapter 2 is a right-angle elbow, the adapter 2 has a front interface and a lower interface, the waterway plate 1 has a connection port, the lower interface is fixedly connected to the filter element 3, and the front interface is plugged into the connection port. The above are all conventional structures of existing products, and their detailed connection structures and methods are all well-known technologies, and this application will not repeat them.

[0025] The device further comprises: a buckle 4 and a clamping block 5.

[0026] like Figure 3 As shown, the buckle 4 includes a pressing portion 41, a first arm 43 and a second arm 44 fixedly connected at both ends of the pressing portion 41, and the actual buckle is in a C shape; the middle parts of the first arm 43 and the second arm 44 are respectively hinged on the top peripheral side wall of the adapter 2, and the two opposite sides of the top peripheral side wall of the adapter 2 are respectively provided with a convex pin, so that the middle parts of the first arm 43 and the second arm 44 are respectively hinged on the convex pin.

[0027] The upper sides of the ends of the first arm 43 and the second arm 44 are each provided with a bayonet 45 of the same shape; the bayonet 45 is arranged adjacent to the connection port.

[0028] 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 .

[0029] The pressing portion 41 is pressed down from top to bottom, the first arm 43 and the second arm 44 rotate around their hinges, 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 2 to prevent the adapter 2 from moving away from the waterway plate 1 along the axial direction of the front interface.

[0030] 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.

[0031] When the adapter 2 is plugged into the connection port, the entrance of the bayonet 45 is adjacent to the bottom side of the clamping block 5 .

[0032] 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 .

[0033] The first side wall has a vertical surface at the bottom, and a first protrusion 47 at the top of the vertical surface.
