[0002] The water purifier is a water treatment equipment for deep filtration and purification of water quality, which purifies water through a filter core, and the water reaches a certain cleanliness after passing through the filter core in the water purifier. However, with the extension of use time, impurities in the water will block the filter core, and the filter core needs to be replaced to maintain the filtering effect of the water. At present, most filter cores on the market are connected with the waterway board of the water purifier by thread connection or rotary buckle connection. When inserting or rotating the filter core, the operator needs to overcome the friction between the filter core and the water purifier. In addition, there is no good force applying structure on the filter core, and in the limited force applying space, the operation is difficult and time-consuming.

[0003] In addition, when replacing the filter core, the water inlet valve outside the water purifier needs to be closed to prevent water from the external water source from flowing out of the waterway board of the water purifier. In addition, there is water storage in the filter core and the waterway board of the water purifier. After closing the water inlet valve, the water storage in the filter core and the waterway board will still flow out of the water inlet and outlet, causing the water purifier to fail to transmit water to the newly replaced filter core in time, not only wasting water resources, but also splashing the operator's clothes and shoes, or flowing to the floor, causing inconvenience to the use of the water purifier. In addition, dust or bacteria may enter the newly replaced filter core from the water inlet of the filter core during installation, polluting the filter core and thus polluting the water resources.

[0040] In the description of the utility model, it should be pointed out that unless otherwise specified and limited, the terms "setting", "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be connected through an intermediate medium, it can be the communication between the two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0041] The existing water purifier usually adopts threaded connection or rotating buckle connection to connect the filter element. When installing or dismounting the filter element, the operator needs to overcome the friction between the filter element and the water purifier. In addition, there is no good force applying structure on the filter element, and in the limited force applying space, the operation is difficult, and the replacement takes a long time. In addition, the waterway plate and the filter element of the existing water purifier are usually not provided with a water stop valve. Therefore, when the filter element is replaced, the stored water in the filter element and the waterway plate of the water purifier will flow out from the water inlet and outlet of the filter element and the waterway plate, which causes the water purifier to be unable to timely transmit water to the newly replaced filter element, not only wastes water resources, but also splashes the operator's clothes, shoes, or flows to the floor, causing inconvenience to the use of the water purifier.

[0042] Based on this, the utility model provides a pop-up type filter element mounting structure. By installing a locking structure and an unlocking structure on the base, when the filter element is mounted to the base, the locking structure moves and automatically locks the filter element. When the filter element needs to be dismounted, the unlocking structure triggers the locking structure to move to release the filter element, thereby realizing quick and convenient installation and dismounting of the filter element and the base.

[0043] Please refer to Figure 1 The embodiment of the application provides a pop-up filter core mounting structure, which comprises a filter core 10, a base 20, a locking structure 30 and an unlocking structure 40. The filter core 10 is pluggably mounted to the base 20. The locking structure 30 is movable relative to the base 20 between a locking position for locking the filter core 10 and an unlocking position for releasing the filter core 10. The unlocking structure 40 triggers the locking structure 30 to move to the unlocking position under the action of an external force and pushes the filter core 10 to move outwardly towards the base 20, so that the filter core 10 can be detached from the base 20.

[0044] Compared with the prior art, the filter core protruding portion and the locking block of the locking member are misaligned or partially abutted by the movement of the locking member, so that the locking and unlocking of the filter core and the base are realized. The user can replace the filter core without overcoming additional locking force, the operation is convenient, and the necessary space for disassembly operation is saved.

[0045] Please refer to Figures 1-6 Further, in some embodiments, the bottom of the filter core 10 is provided with a plug-in portion 11, and the outer wall of the plug-in portion 11 is provided with a protruding portion 12. The bottom of the protruding portion 12 has an inclined surface for guiding.

[0046] Further, the locking structure 30 comprises a locking member 31, a locking block 32 and a limiting member 33. The locking member 31 is internally provided with a through hole corresponding to the plug-in portion, and is movable relative to the base 20 between a locking position for locking the filter core 10 and an unlocking position for releasing the filter core 10. The locking block 32 is arranged on the inner wall of the locking member 31. The locking block 32 is provided with a sliding surface matched with the inclined surface of the protruding portion 12. When the locking structure 30 is in the locking position and locks the filter core 10, the locking block 32 can be blocked in front of the protruding portion 12 in the disassembly direction of the filter core 10.

[0047] Further, the limiting member 33 is fixedly arranged on the base 20 and comprises a groove through which the protruding portion 12 passes. The locking block 32 and the limiting member 33 are sequentially arranged in the disassembly direction of the filter core 10. Through the movement of the locking member 31, the projection of the locking block 32 and the groove of the limiting member 33 on the horizontal plane at least partially overlaps or is misaligned, that is, when the locking structure 30 is in the locking position, the projection of the locking block 32 and the groove of the limiting member 33 on the horizontal plane at least partially overlaps, and when the locking structure 30 is in the unlocking position, the locking block 32 and the groove of the limiting member 33 are misaligned, or the part of the locking block 32 not overlapping with the groove can allow the protruding portion 12 to move up and down. When the filter core 10 and the base 20 are assembled, at least one protruding portion 12 enters the through hole 311 along the groove of the limiting member 33, so that the relative sliding between the inclined surface of the protruding portion 12 and the sliding surface of the locking block 32 occurs, and the plug-in portion 11 is uniformly inserted into the base 20.

[0048] In some embodiments, the insertion portion 11 is cylindrical, and the moving direction of the locking member 31 is the circumferential direction of the filter element 10. In other embodiments, the cross section of the insertion portion 11 is waist-shaped or rectangular, and the moving direction of the locking member 31 is the length direction of the insertion portion.

[0049] In some embodiments, the number of the protruding portions 12 is one, two or more. In the embodiments where the number of the protruding portions 12 is more than one, the structures of the protruding portions 12 can be the same or different, and the protruding portions 12 are arranged in intervals along the moving direction of the locking member 31.

[0050] In some embodiments, the number of the locking blocks 32 is one, two or more. In the embodiments where the number of the locking blocks 32 is more than one, the structures of the locking blocks 32 can be the same or different, and the locking blocks 32 are arranged in intervals along the moving direction of the locking member 31. When the locking structure 30 is in the locked position, the plurality of locking blocks 32 can limit the protruding portions 12 in multiple positions, improve the locking effect of the filter element 10, and improve the stability of the pop-up filter element structure.

[0051] Further, the number of the protruding portions 12 and the locking blocks 32 is equal or different, and when the filter element 10 is locked in the base 20, the protruding portions 12 and the locking blocks 32 abutting thereto form a locking site, and the number of the locking sites is at least two. Preferably, the number of the protruding portions 12 and the locking blocks 32 is equal, and the positions correspond.

[0052] In some embodiments, the limiting member 33 includes at least one groove with a size slightly larger than the protruding portion 12, and the at least one groove corresponds to the position of the protruding portion 12 to limit the insertion portion 11. In other embodiments, the limiting member 33 includes a plurality of grooves, and the plurality of grooves are arranged in intervals along the moving direction of the locking member 31, correspond to the protruding portions 12 one by one, and overlap with the projection part of the adjacent locking block 32 in the horizontal plane. The grooves limit the insertion portion 11, so that it can interact with the locking block 32 to achieve locking.

[0053] Further, at least one first reset member 34 is arranged in the moving direction of the locking member 31, and the rebound force of the first reset member 34 moves the locking member 31 from the unlocked position to the locked position, and the locking block 32 blocks in front of the protruding portion 12 along the disassembly direction of the filter element 10, so that the filter element 10 is automatically locked when the filter element 10 and the base 20 are installed.

[0054] Referring to Figure 5 In some embodiments, the first reset member 34 is a reset spring, and is arranged along the moving direction of the locking member 31, and the two ends thereof abut with the locking member 31 and the base 20 respectively.

[0055] Further, the unlocking structure 40 comprises an unlocking piece 41, which is fixed to the locking piece 31 and protrudes from the outer wall of the locking piece 31. The base 20 is provided with a sliding groove for the movement of the unlocking piece 41. The movement of the unlocking piece 41 in the sliding groove can drive the locking piece 31 to move from the locking position to the unlocking position, the protruding part 12 of the plug-in part is misaligned with the locking block 32, and the filter element 10 and the base 20 are unlocked. At this time, the filter element 10 can be disassembled from the base 20. Because the water in the waterway between the filter element 10 and the base 20 has a certain water pressure, the filter element 10 can be ejected in the disassembly direction under the action of the water pressure. The protruding part 12 is blocked in front of the locking block 32 along the movement direction of the locking piece 31 or the plug-in part 11, so as to avoid relocking the filter element 10, and facilitate the subsequent disassembly of the filter element 10.

[0056] Referring to Figures 6-7 In some embodiments, the unlocking piece 41 can be provided as a lever. The filter element 10 can be unlocked by pulling the unlocking piece 41.

[0057] In some embodiments, the outer wall of the locking piece 31 is provided with a notch, one end of the unlocking piece 41 abuts against the notch of the locking piece 31, and the other end is rotationally or slidably connected to the base 20. The unlocking piece 41 is rotated or slid under the action of an external force, and the rotation or sliding of the unlocking piece 41 drives the locking piece 31 to move to the unlocking position, thereby unlocking the filter element 10.

[0058] Further, the unlocking structure 40 further comprises a second reset piece 42, which is arranged along the movement direction of the plug-in part 11 and is fixed to the filter element 10 or the base 20. The rebound force of the second reset piece 42 drives the filter element 10 to move in the disassembly direction, and the protruding part 12 moves to the front of the locking block 32 in the disassembly direction, thereby increasing the distance of the automatic ejection of the filter element 10 during unlocking, avoiding that the water pressure is not enough to eject the filter element 10, and causing the filter element 10 to be locked again by the locking structure 30 after being pulled out.

[0059] Further, in some embodiments, the unlocking structure 40 further comprises a motor. A rotating piece is fixed to the output shaft of the motor, and the rotating piece abuts against one side of the unlocking piece 41. The motor drives the rotating piece to rotate to push the unlocking piece 41 to move, thereby driving the locking piece 31 to move from the locking position to the unlocking position. The motor is electrically connected to a controller, which can be controlled by the buttons or other structures of the external water purifier. In some embodiments, the controller is electrically connected to the buttons arranged on the base 20 or the external water purifier, and the unlocking of the locking structure 30 is realized by pressing the buttons. When the user starts the motor through the external buttons, the output shaft of the motor drives the rotating piece to rotate, thereby pushing the unlocking piece 41 to move in the sliding groove. The movement of the unlocking piece 41 drives the locking piece 31 to move from the locking position to the unlocking position. At this time, the filter element 10 is automatically ejected under the action of the water pressure and the second reset piece 42.
