[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0041] This utility model provides a water purification device, including a filter element structure. Raw water is filtered through the filter element structure to produce purified water for user use. The water purification device can be a water purifier, a water dispenser with purification function, a water softener, or other equipment; no limitation is made here.
[0042] The filter element structure includes a filter bottle, a mounting frame, and a filter element handle cover. The filter element handle cover is connected to the filter bottle and is used by the user to hold it during disassembly and assembly, improving the ease of operation. The mounting frame is provided with a receiving groove, in which the filter bottle is placed to improve the modularity of the filter element structure.
[0043] Optionally, a water circuit assembly is provided on the mounting frame, which is connected to the filter bottle to allow raw water to flow in, purified water to flow out, and concentrated water to be discharged. It should be noted that the filter bottle and water circuit assembly are conventional structures in this field and will not be described in detail here.
[0044] In the existing technology, the process of fixing and disassembling the filter bottle and the mounting frame is cumbersome, time-consuming, and laborious. It is easy for the filter bottle to be improperly installed or difficult to disassemble, which affects the user experience.
[0045] To address the aforementioned issues, this embodiment improves the structure of the filter element handle cover, enabling it to be quickly attached and detached from the mounting frame for easier assembly and disassembly, thus enhancing the user experience.
[0046] Specifically, such as Figure 1 As shown, the filter cartridge handle cover includes a cover body 10, a handle 20, and a locking assembly 30. The cover body 10 is connected to the filter bottle, and the handle 20 is rotatably mounted on the cover body 10, allowing the handle 20 to be adjusted in position according to user needs. When the handle 20 protrudes from the cover body 10, it is in use, facilitating the user's gripping of the handle 20 for filter bottle installation and removal. When the handle 20 is flush with the cover body 10, it is in the closed state, preventing the handle 20 from protruding from the cover body 10 and thus avoiding interference with the installation and use of the filter cartridge structure. The locking assembly 30 is movably disposed within the cover body 10 and engages with the handle 20. The locking assembly 30 includes a mating part 31 that engages with a locking part provided on the side wall of the receiving groove. The mating part 31 can move according to the state of the handle 20 to engage with or disengage from the locking part. When the handle 20 is turned to the use position, the mating part 31 moves and retracts into the cover 10 as the handle 20 is turned, thereby disengaging the mating part 31 from the locking part. At this time, the user can pull the filter bottle out of the receiving groove by holding the handle 20 to disassemble the filter bottle. When the handle 20 is turned to the closed position, the mating part 31 can move and extend out of the cover 10 as the handle 20 is turned, thereby allowing the mating part 31 to be inserted into the locking part. The mating part 31 and the locking part fix the filter bottle in the mounting frame, thereby locking the filter bottle to the mounting frame.
[0047] In this embodiment, during the disassembly and assembly of the filter bottle, the user only needs to turn the handle 20 without the need for auxiliary tools. The operation is convenient and labor-saving, and takes little time, enabling quick disassembly and assembly, which greatly improves the user experience.
[0048] In this embodiment, the locking part is a mating groove, and the mating part 31 is inserted into the mating groove to prevent the filter bottle from detaching from the mounting frame. In other embodiments, the locking part can be other structures, as long as it can cooperate with the mating part 31 to lock.
[0049] like Figure 1 and Figure 2As shown, a boss 111 is provided on the top surface of the cover 10. Both ends of the handle 20 are connected to the circumferential sidewalls of the boss 111, allowing the handle 20 to span across the boss 111. When the handle 20 is in use, it is approximately perpendicular to the top surface of the boss 111, creating a space between the handle 20 and the top surface of the boss 111. This space allows the user's hand to pass through and grip the handle 20, facilitating the disassembly, assembly, or movement of the filter bottle. When the handle 20 is in the closed state, it is approximately coplanar with the boss 111, and is circumferentially arranged around the boss 111, preventing it from protruding beyond the boss 111 and thus avoiding interference with other structures.
[0050] In this embodiment, the handle 20 is semi-circular and the boss 111 is circular, so that the handle 20 can better fit the outer contour of the boss 111 when it is in the closed state.
[0051] In some other embodiments, the shapes of the handle 20 and the boss 111 can be adjusted according to actual needs. For example, the boss 111 can be a square boss, and correspondingly, the handle 20 is roughly U-shaped, as long as the handle 20 can be sleeved on the outside of the boss 111 along the circumference of the boss 111.
[0052] In some other embodiments, the position of the handle 20 in the use state and the closed state can be adjusted according to actual needs, as long as it is convenient for the user to disassemble and assemble the filter bottle and drive the mating part 31 to move.
[0053] To facilitate the user's rotation of handle 20, such as Figure 3 As shown, a notch 211 is provided on the handle 20. The notch 211 can reduce the local size of the handle 20, making it easier for the user to hold the handle 20 and drive the handle 20 to rotate.
[0054] In this embodiment, the notch 211 is provided on the side surface of the handle 20 facing the cover 10 when the handle 20 is in the closed state, so that there is a gap between the handle 20 and the cover 10 when the handle is in the closed state, and the user can rotate the handle 20 through the gap, making the operation more convenient.
[0055] In some other embodiments, the notch 211 may also be located in other positions, as long as it allows the user to easily rotate the handle 20.
[0056] Combination Figure 2 and Figure 4As shown, the cover 10 has a receiving cavity, and at least part of the locking component 30 is disposed within the receiving cavity to prevent exposure. The circumferential sidewall of the cover 10 has a through hole 121 communicating with the receiving cavity. The mating part 31 slides radially with the cover 10, and the mating part 31 can slide through the through hole 121 to extend or retract with the rotation of the handle 20. In this embodiment, setting the movement direction of the mating part 31 to the radial direction of the cover 10 and fitting it with the through hole 121 makes it easier for the mating part 31 to engage with the locking part on the mounting frame. No changes are needed to the structure of the filter bottle; only the locking part needs to be added to the mounting frame. This simple structure helps reduce costs.
[0057] like Figure 4 As shown, the locking assembly 30 also includes an elastic element 32 and a transmission element 33. The elastic element 32 is disposed inside the cover 10 and is connected to the mating part 31. The elastic force of the elastic element 32 can drive the mating part 31 to extend out of the cover 10. That is, the direction of the elastic force applied by the elastic element 32 to the mating part 31 is radially outward of the cover 10. The elastic element 32 provides locking force for the mating part 31 and the locking part to improve the fixing effect between the filter bottle and the mounting frame. The transmission element 33 is disposed inside the cover 10 and can slide along the axial direction of the cover 10. The transmission element 33 is in transmission engagement with the handle 20, and the transmission element 33 slides against the mating part 31 to push the mating part 31 back into the receiving cavity. By setting the transmission element 33, the rotation of the handle 20 and the movement of the mating part 31 are linked together to realize the quick assembly and disassembly of the filter bottle.
[0058] In this embodiment, the mating part 31 is provided with a first abutting surface 311, and the transmission member 33 slides with the first abutting surface 311. The height of the first abutting surface 311 gradually decreases from the inside to the outside along the radial direction of the cover 10. When the transmission member 33 moves away from the handle 20 along the axial direction of the cover 10, the transmission member 33 applies a pushing force to the mating part 31 by pushing the first abutting surface 311, causing the mating part 31 to overcome the elastic force of the elastic member 32 and move radially towards the inside of the cover 10, so that the mating part 31 retracts into the cover 10 and disengages from the locking part. When the transmission member 33 moves towards the handle 20 along the axial direction of the cover 10, the pushing force applied by the transmission member 33 to the first abutting surface 311 decreases, causing the mating part 31 to move radially towards the outside of the cover 10 under the action of the elastic member 32, so that the mating part 31 gradually extends out of the cover 10 and engages with the locking part.
[0059] To reduce the friction between the transmission component 33 and the mating part 31, the transmission component 33 can make line contact with the mating part 31 to reduce the contact area and thus reduce sliding friction.
[0060] In other embodiments, the end of the transmission member 33 that contacts the mating part 31 may be provided with a rolling element, such as a ball or a roller, so that the friction between the transmission member 33 and the mating part 31 is rolling friction. The rolling friction is small, thereby reducing wear and making the extension and retraction of the mating part 31 smoother.
[0061] To improve the stability of the movement of the transmission component 33, a guide component 13 is provided in the cavity. The guide component 13 slides with the transmission component 33 along the axial direction of the cover 10 to guide the transmission component 33 and ensure that the movement direction of the transmission component 33 is accurate.
[0062] In this embodiment, the guide member 13 is a guide plate with a sliding hole. The transmission member 33 slides through the sliding hole to guide the transmission member 33.
[0063] In other embodiments, the guide member 13 can be a slide rail or slide groove that cooperates with the transmission member 33, as long as it can provide guidance for the sliding of the transmission member 33.
[0064] Continue as Figure 4 As shown, the handle 20 includes a handle body 21, a rotating shaft 22, and a cam 23. The handle body 21 is disposed on the outer side of the cover 10 for the user to grip. The rotating shaft 22 is connected to the handle body 21 and rotatably passes through the cover 10 to extend into the receiving cavity. In this embodiment, the rotating shaft 22 is rotatably connected to the circumferential sidewall of the boss 111. The cam 23 is located in the receiving cavity and connected to the rotating shaft 22, and the cam 23 abuts against the transmission member 33. When the user rotates the handle body 21, the handle body 21 drives the cam 23 to rotate through the rotating shaft 22. The cam 23 pushes the transmission member 33 to slide along the axial direction of the cover 10, thereby pushing the mating part 31 to slide.
[0065] In this embodiment, the cam 23 and the transmission component 33 work together to push the mating part 31. The transmission structure is simple, and the size of the cam 23 can be set to be small, which reduces the space occupied and helps to control the overall size of the filter element handle cover.
[0066] To make the locking assembly 30 more compact, the transmission member 33 is provided with a second abutment surface 331. The cam 23 abuts against the second abutment surface 331, and the height of the second abutment surface 331 gradually decreases from the inside to the outside along the radial direction of the cover 10. By providing an inclined second abutment surface 331, part of the transmission member 33 can utilize the internal space corresponding to the boss 111, which helps to reduce the axial dimension of the filter element handle cover.
[0067] To ensure more reliable fixing of the filter bottle to the mounting frame, the locking assembly 30 includes at least two mating parts 31. These two mating parts 31 are spaced apart circumferentially along the cover 10 to increase the number of fixing positions between the filter bottle and the mounting frame, thus improving the fixing effect. In this embodiment, two mating parts 31 are provided, located on opposite sides of the cover 10. The two ends of the elastic member 32 are connected to the corresponding mating parts 31 to simultaneously apply elastic force to both mating parts 31, which simplifies the structure.
[0068] In other embodiments, the number of mating parts 31 can be set according to actual needs, and is not limited here.
[0069] To facilitate the installation of the locking assembly 30, the cover 10 includes a detachable upper cover 11 and a filter bottle cover 12, forming a receiving cavity between the upper cover 11 and the filter bottle cover 12. The handle 20 is rotatably connected to the upper cover 11, and the filter bottle cover 12 is connected to the filter bottle. By setting the cover 10 to have a detachable upper cover 11 and filter bottle cover 12, the locking assembly 30 can be easily disassembled and maintained.
[0070] In this embodiment, the top cover 11 includes a first top plate and a first annular side plate, with the first top plate forming a boss 111; the filter bottle cover 12 includes a second top plate, a second annular side plate and a third annular side plate, with the second annular side plate and the third annular side plate located on opposite sides of the second top plate, the second annular side plate being detachably connected to the first annular side plate of the top cover 11, and the third annular side plate being connected to the filter bottle.
[0071] In other embodiments, the top cover 11 and the filter bottle cover 12 can also be other structures, as long as they can form a receiving cavity and be connected to the filter bottle.
[0072] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
