[0029] Reference Figure 1 As shown, the side-insertion filter element fixing structure according to the embodiment of the utility model includes a filter element 100, a waterway plate 200 and a fixing cover 300. The filter element 100 includes a filter bottle 140 and a bottle cover 110 installed on the filter bottle 140. The side wall of the bottle cover 110 has a clamping member 120 and a flow channel 130 connected to the outside; the waterway plate 200 has a water connector 210, and the water connector 210 can be inserted into the flow channel 130 along the radial direction of the filter element 100; Figure 2 As shown, one end of the fixed cover 300 is rotatably mounted on the waterway plate 200. Figure 1 , 3 As shown, the fixing cover 300 has a lower opening snap-fitting groove 310 , and the snap-fitting member 120 is snap-fitted to the snap-fitting groove 310 so that the fixing cover 300 blocks the water connector 210 from moving along the radial direction of the filter element 100 and thereby fixes the water connector 210 on the bottle cap 110 .

[0030] By providing a rotatable fixing cover 300 on the waterway plate 200, when the water connector 210 is inserted into the bottle cap 110, the fixing cover 300 is rotated so that the snap-in groove 310 of the fixing cover 300 is snap-connected with the snap-in piece 120 of the bottle cap 110, so that the fixing cover 300 cannot rotate on its own. The fixing cover 300 can prevent the water connector 210 from moving out of the flow channel 130 of the bottle cap 110, thereby ensuring that the waterway plate 200 is fixed on the bottle cap 110, avoiding the risk of water leakage between the filter element 100 and the waterway plate 200.

[0031] When the waterway plate 200 is installed, the water connector 210 is inserted into the circulation channel 130, and the user drives the fixed cover 300 to rotate downward so that the snap-in groove 310 is snap-connected with the snap-in piece 120; when the waterway plate 200 is disassembled, the user drives the fixed cover 300 to rotate upward so that the snap-in groove 310 is disengaged from the snap-in piece 120, and the water connector 210 of the waterway plate 200 is taken out from the circulation channel 130 of the upper bottle cap 110.

[0032] In some embodiments of the present invention, Figure 1 As shown, the rear side wall of the bottle cap 110 has a flow channel 130, the left side wall of the bottle cap 110 has a clamping member 120, and the fixing cover 300 is U-shaped. Figure 2 As shown, the fixed cover 300 and the waterway plate 200 jointly surround the bottle cap 110, so that the structure of the fixed cover 300 and the waterway plate 200 is small, and it is ensured that the fixed cover 300 can prevent the water connector 210 from moving outward.

[0033] In a further embodiment of the present invention, Figure 4 As shown, the clamping member 120 includes a first side wall 121 and a second side wall 122 that are relatively arranged, the top of the first side wall 121 has a first protrusion 123 that protrudes away from the second side wall 122, the clamping groove 310 includes a third side wall 311 and a fourth side wall 312 that are relatively arranged, the bottom of the third side wall 311 has a second protrusion 313 that protrudes toward the fourth side wall 312, the first protrusion 123 is clamped and connected with the second protrusion 313, that is, the fixed cover 300 is clamped and connected with the bottle cap 110 through the first protrusion 123 and the second protrusion 313, so that the clamping member 120 can both position the rotation of the fixed cover 300 and block the self-rotation of the fixed cover 300, without the need to set up an additional positioning structure, so that the structure of the bottle cap 110 and the fixed cover 300 is simple.

[0034] Since the clamping member 120 needs to block the rotation of the fixing cover 300, when the fixing cover 300 is driven to rotate, the second protrusion 313 will block the rotation of the fixing cover 300. The user needs to forcefully drive the fixing cover 300 to rotate so that the first protrusion 123 overcomes the obstruction of the second protrusion 313 to achieve the clamping connection between the clamping member 120 and the clamping slot 310 and the separation between the clamping member 120 and the clamping slot 310.

[0035] Specifically, Figure 4 As shown, the first protrusion 123 includes an upper bevel 1231, a lower bevel 1232 and a connecting edge 1233, and the two ends of the connecting edge 1233 are respectively connected to one end of the upper bevel 1231 and one end of the lower bevel 1232, and the distance between the end of the lower bevel 1232 connected to the connecting edge 1233 and the first side wall 121 is greater than the distance between the upper bevel 1231 and one end of the connecting edge 1233 and the first side wall 121, and the second protrusion 313 includes an inclined edge 3131 and an arc edge 3132, and the upper end of the arc edge 3132 is connected to the inclined edge 3131. The first protrusion 123 and the second protrusion 313 adopt the above structure to facilitate the clamping connection between the clamping member 120 and the clamping groove 310 and the separation of the clamping member 120 from the clamping groove 310.

[0036] In a further embodiment of the utility model, both the abutment points between the first protrusion 123 and the second protrusion 313 and the abutment points between the second protrusion 313 and the first protrusion 123 have arc transitions. The first protrusion 123 and the second protrusion 313 are provided with arc transition sections to facilitate the snap connection between the snap connector 120 and the snap groove 310 and the separation between the snap connector 120 and the snap groove 310.
