[0020] The following is a further description of the clip-on filter element docking structure of the utility model through embodiments and in conjunction with the accompanying drawings.

[0021] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0022] In the present invention, unless otherwise expressly specified or limited, the terms "connect", "fixed" and the like shall be interpreted in a broad sense.

[0023] For example, "fixed" can be fixed connection, detachable connection, or integrated; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium, can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] See also Figures 1 to 5 As shown, the utility model proposes a clip-type filter element docking structure, which is characterized by comprising a waterway plate 1, a filter element 2 installed on the waterway plate 1, and a quick-installation structure arranged on the filter element 2 and connected to the waterway plate 1, the quick-installation structure comprising a connecting seat 30 installed on the top of the filter element 2, a clip installed on the waterway plate 1 and docked with the connecting seat 30, and a knob 31 movably installed on the connecting seat 30 to drive the clip to move, the clip comprises a clamping arm 32 movably installed on the waterway plate 1, and a telescopic block 33 movably installed on the waterway plate 1 for driving the clamping arm 32 to clamp or open, and a tension spring 34 connected to the clamping arm 32 for driving the telescopic block 33 to reset is installed on the waterway plate 1, The telescopic block 33 is provided with a boss 35, the knob 31 is provided with a reset groove 36 matched with the boss 35, the waterway plate 1 is provided with a pipe mouth 11, and the connecting seat 30 is provided with a docking pipe 12 plugged into the pipe mouth 11; through the setting of the quick-release structure, the problem that the filter element 2 and the waterway plate 1 require a large force to complete the interference assembly is solved, and the quick buckling and fixing are achieved during the docking process between the connecting seat 30 and the waterway plate 1, which saves time and effort and is easy to operate; through the setting of the tension spring 34, when the waterway plate 1 and the connecting seat 30 are not assembled, the telescopic block 33 protrudes from the waterway plate 1 so that the clamping arm 32 is in an open state, which is convenient for the installation of the docking pipe 12 and the pipe mouth 11.

[0025] The clamping arm 32 is provided with a plurality of snap blocks 37, the connecting seat 30 is provided with a slot 38 that is snap-fitted with the snap block 37, the knob 31 is also provided with a plurality of friction grooves 39 that are easy to operate, the snap block 37 and the slot 38 are both provided with matching guide slopes 40, and the waterway plate 1 is provided with a rotating shaft 41 that is easy to install the clamping arm 32; by setting the guide slope 40, the problem of interference caused by the position difference formed when the clamping arm 32 is rotated can be avoided, and it is ensured that the snap block 37 can be quickly buckled in the slot 38, thereby improving the assembly efficiency; by setting the friction groove 39, when the operator rotates the knob 31, the friction between the knob 31 and the finger is increased, thereby facilitating the operation.

[0026] When the utility model is used, align the butt joint pipe 12 with the pipe mouth 11, observe the position of the reset groove 36 on the knob 31, rotate the knob 31 to stagger the reset groove 36 and the telescopic block 33, push the filter element 2 to insert the butt joint pipe 12 into the pipe mouth 11, and during the insertion process, the outer side of the knob 31 contacts the boss 35 and pushes the boss 35, so that the telescopic block 33 retracts inward and stretches the tension spring 34, and the telescopic block 33 pushes the clamping arm 32 to rotate on the rotating shaft 41, so that the clamping arm 32 is buckled in the direction of the slot 38 until the buckle block 37 is completely buckled. When the filter element 2 needs to be removed, the knob 31 is rotated to align the reset groove 36 with the telescopic block 33. At this time, the telescopic block 33 is no longer squeezed by the side of the knob 31. The telescopic block 33 is pushed into the reset groove 36 under the resilience of the tension spring 34. At the same time, the tension spring 34 pulls the clamping arm 32 to rotate on the rotating shaft 41, so that the clamping arm 32 is separated from the slot 38. The clamping arm 32 is in an open state, and finally the docking tube 12 can be pulled out from the pipe mouth 11.

[0027] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
