Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

As shown in fig. 1 to 8, the present embodiment provides a filter element locking structure for a water purifier, where the water purifier includes a filter element 1, and the filter element locking structure includes a locking member 2 and a mounting member 3; the mounting piece 3 is provided with a fixing plate 31 which is matched with the fixing part 11 of the filter element 1, and the fixing plate 31 is provided with a slot 32; the locking piece 2 is provided with a clamping jaw 21, a clamping groove 12 is formed in the fixing portion 11, the clamping jaw 21 is used for being inserted into the inserting groove 32 and matched with the clamping groove 12, and therefore the filter element 1 is fixed to the mounting piece 3.

The filter insert 1 is fixed to the mounting member 3 by inserting the claws 21 of the lock member 2 into the insertion grooves 32 of the mounting member 3 and fitting the claws 21 into the engagement grooves 12 provided in the filter insert 1. The filter element fixing mode can realize the fixation or the release of the filter element 1 only by matching or separating the claw 21 of the locking piece 2 with or from the clamping groove 12 of the filter element 1, has firm fixation and simple and convenient core replacement, and is not limited by the size of the filter element 1.

The fixing plate 31 may be provided with a socket 33 inserted and matched with the fixing portion 11, the socket 32 is communicated with the socket 33, the claw 21 is inserted into the socket 32, and the edge 211 of the claw 21 extends into the socket 33 and is matched with the slot 12. Like this, it is more firm to fix between filter core 1 and the installed part 3 to adopt the grafting cooperation between filter core 1 and the installed part 3, can make things convenient for the installation and the dismantlement of filter core 1.

As shown in fig. 1 to 4, in an exemplary embodiment, the filter cartridge 1 is provided with a plurality of fixing portions 11, the insertion openings 33, the insertion grooves 32 and the claws 21 are all provided in a plurality, each insertion opening 33 is used for being inserted and matched with a corresponding one of the fixing portions 11, and one insertion groove 32 is inserted and matched with a corresponding one of the claws 21. The locking member 2 may include a plate body, a plurality of notches 22 are formed in one side edge of the plate body at intervals, and the solid portions of the plate body located on two sides of the notches 22 form a plurality of claws 21. A plurality of the insertion holes 33 may be arranged side by side, each insertion hole 33 may extend from a front side or a rear side of the fixing plate 31 to an opposite side, and the insertion groove 32 may extend downward from a top surface of the fixing plate 31. The inserting holes 33 and the inserting holes 32 are alternately arranged, one inserting hole 32 is communicated with the interiors of two adjacent inserting holes 33, the width of one claw 21 is larger than the minimum distance between the two adjacent inserting holes 33 corresponding to the width of the claw 21, so that two side edges 211 of one claw 21 can respectively extend into the two adjacent inserting holes 33, one side edge 211 of one claw 21 is clamped on the fixing part 11 in one inserting hole 33, and the other side edge 211 of the claw 21 is clamped on the fixing part 11 in the other inserting hole 33. Thus, each fixing part 11 of the filter element 1 is respectively clamped by the edges 211 of the two claws 21 at the two sides, and the fixing is firm. Wherein, the fixed part 11 of filter core 1 can be the column, for example cylindricly, draw-in groove 12 can be annular circumference and set up on the outer wall of fixed part 11, and the edge 211 card of jack catch 21 is gone into the draw-in groove 12 and is located the regional of fixed part 11 lateral part, and like this, the fixed part 11 of filter core 1 can not axial displacement, can not deviate from socket 33 to be fixed in socket 33.

When the filter element 1 is installed, the fixing portion 11 of the filter element 1 can be inserted into the insertion opening 33 of the installation member 3, then the claws 21 of the locking member 2 are inserted downwards into the corresponding insertion grooves 32, and after the claws 21 are inserted in place, the claws 21 are clamped into the clamping grooves 12 of the fixing portion 11, so that the fixing portion 11 of the filter element 1 is fixed in the insertion opening 33 of the installation member 3, and then the filter element 1 is locked. When the filter cartridge 1 needs to be disassembled, the locking member 2 can be moved upwards, so that the claws 21 of the locking member 2 are disengaged from the clamping grooves 12 of the fixing part 11 of the filter cartridge 1, the filter cartridge 1 is released, and the fixing part 11 of the filter cartridge 1 can be moved out of the insertion opening 33 of the mounting member 3.

In order to prevent the locking members 2 from being reversely installed, the intervals between the insertion grooves 32 may be set to be unequal, so that each of the claws 21 can only be engaged with the corresponding insertion groove 32 when the locking members 2 are installed. Wherein, the distance between two slots 32 is matched with the distance between two corresponding claws 21. Or, in order to prevent the locking member 2 from being reversely installed before and after the installation, the groove widths of the locking grooves 12 may be set to be different, so that each claw 21 of the locking member 2 can only be matched with the corresponding locking groove 12 when the installation is performed. Wherein, the width of the slot 12 on each fixing part 11 is matched with the width of the corresponding claw 21.

As shown in fig. 1 and 2, the fixing part 11 of the filter element 1 may be a water inlet of the filter element 1, and may include a water inlet, a water outlet and a flushing port, and the mounting part 3 may be a water channel plate of a water purifier. The three water gaps are respectively inserted into the three sockets 33 on the waterway plate, and each water gap is in sealing fit with the socket 33 where the water gap is located, so that the water leakage is ensured. Wherein, can set up seal groove 13 on the outer wall of three mouth of a river, realize the sealed between mouth of a river and socket 33 through the sealing washer of installing in seal groove 13.

As shown in fig. 1, 5-8, the fastening portion 11 of the filter cartridge 1 is not shown in fig. 8, and in another exemplary embodiment, a plurality of insertion openings 33 are arranged side by side, the insertion groove 32 is arranged as a through groove communicating with each of the insertion openings 33, each insertion opening 33 extends from the front side surface or the rear side surface of the fastening plate 31 to the opposite side, and the insertion groove 32 extends downward from the top surface of the fastening plate 31. The width of the plate body of the locking element 2 can be adapted to the length of the insertion groove 32. After the locking member 2 is inserted into the slot 32, two side edges 211 of each of the claws 21 respectively extend into two adjacent sockets 33, so that one side edge 211 of one claw 21 is clamped on the fixing part 11 in one of the sockets 33, the other side edge 211 of the claw 21 is clamped on the fixing part 11 in the other socket 33, and the fixing part 11 in each socket 33 is respectively located in a corresponding one of the notches 22. The bottom wall 221 of the notch 22 may be arc-shaped, and is adapted to the ring slot 12 of the fixing portion 11, and is clamped in the upper region of the ring slot 12. In this embodiment, since the slot 32 is a through slot, the bottom wall 221 of the gap 22 can be clamped on the upper portion of the corresponding fixing portion 11, so that two sides of one fixing portion 11 are respectively clamped by the respective edges 211 of the two clamping claws 21 on two sides thereof, and the upper portion of the fixing portion 11 is fixed by the gap 22 between the two clamping claws 21 on two sides thereof, so that the upper portion, the left side portion and the right side portion of one fixing portion 11 are clamped and fixed, and the fixing is more reliable.
