When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0027] The utility model provides a bendable filter element, referring to Figures 1 to 3 The filter element comprises a filter element head and a plurality of rotating joints, wherein the filter element head comprises a filter barrel cover, an upper shell and a lower shell; the upper opening of the upper shell is used to sleeve the filter barrel cover, the lower opening of the upper shell is used to accommodate the lower shell, and a connection port is provided on the downward side of the lower shell;

[0028] Each rotating joint includes a connecting piece, a central tube and a lower shell; wherein one end of the connecting piece is a connecting head adapted to the connecting port, and the other end of the connecting piece is a ball head; a groove adapted to the ball head is provided on the upper side of the central tube, and the lower side of the central tube is opened to accommodate the lower shell;

[0029] The connector of the first rotating joint is used to connect the lower shell of the filter element head; the connector of the subsequent rotating joint is used to connect the lower shell of the previous rotating joint;

[0030] All lower shells and center tubes are hollowed out.

[0031] In this embodiment, refer to Figure 2 The filter head of the filter element includes a filter barrel cover, an upper shell and a lower shell. The upper shell is hollow, and the upper opening is used to sleeve the filter barrel cover, and the lower opening is used to accommodate the lower shell of the rotating joint.

[0032] Among them, the filter barrel cover and the upper shell are detachably connected; the upper shell and the lower shell can be detachably connected or fixedly connected.

[0033] Optionally, a connection port is provided on the downward side of the lower shell (i.e., the side facing away from the filter barrel cover), and the connection port has a connecting head adapted thereto.

[0034] Optional, see Figure 3 Each rotating joint of the filter element includes a connector, a central tube and a lower shell. The connector has a connector head at one end and a ball head at the other end, and the connector head fits the connection port of the lower shell and can be detachably connected with the connection port; a groove that fits the ball head is provided on the upper side of the central tube, and when the ball head of the connector is inserted into the groove, not only can the connector and the central tube be detachably connected, but the ball head can also rotate in any direction at a certain angle in the groove; the lower part of the central tube is opened to accommodate the lower shell, and similarly, the central tube and the lower shell can be detachably connected or fixedly connected.

[0035] The connector on the connector of the first rotating joint is used to connect to the connection port in the lower shell of the filter cartridge head, which ensures that the first rotating joint is tightly connected to the bottom part of the filter cartridge head, thereby forming the starting part of the filter cartridge. After the first rotating joint, the connector on the connector of the subsequent rotating joint is used to connect to the connection port in the lower shell of the previous rotating joint. This design allows each rotating joint to be connected in sequence to form a continuous filter cartridge chain, ensuring the structural and functional integrity of the entire filter cartridge.

[0036] This connection method not only makes the assembly and disassembly of the filter element easier and more efficient, but also allows each rotating joint to serve as a rotating joint and to rotate at a certain angle, so that the entire filter element body can be bent to adapt to the requirements of different installation spaces, thereby improving the applicability and flexibility of the water purification equipment in complex installation environments.

[0037] Among them, the rotating joints can be used as universal parts, connected one by one, and the number of rotating joints can be increased or reduced according to the length requirements of the filter element.

[0038] Optionally, when the design specifications of the opening below the upper shell and the opening below the center tube are different, the lower shell of the filter head and the lower shell of each rotating joint are not completely consistent in structure except for the connection port specifications, so as to adapt to the difference between the opening below the upper shell and the opening below the center tube.

[0039] Alternatively, when the lower opening of the upper shell and the lower opening of each central tube are designed to the same specifications, the overall structure of the filter element head and the lower shell in each rotating joint can be designed to the same specifications. Such a unified specification design ensures the interchangeability and compatibility between the lower shells of the filter element and the lower shell installation ports, and simplifies the production and maintenance process.

[0040] Optionally, all lower shells and the central tube are hollowed out and may be designed to be hollowed out at multiple locations to facilitate water flow, thereby effectively filtering impurities and pollutants in the water.

[0041] Optionally, in order to increase the filtering performance of the filter element, after the filter element is assembled, a flexible filter material may be used to wrap or wind around the upper shell and each rotating joint.

[0042] Optionally, the water purification device is provided with a filter barrel for accommodating the filter element; the filter barrel cover is not embedded in the structural part of the upper shell, and is adapted to the inlet of the filter barrel. When the main part of the filter element is inserted into the filter barrel, the filter barrel cover is not embedded in the structural part of the upper shell, and can be closed with the inlet of the filter barrel.

[0043] Optionally, when there is insufficient space around the water purification equipment and it is difficult to remove or install the filter element vertically, the following method can be used: Figure 4 The L-shaped bending method shown, or Figure 5 The U-shaped bending method shown in the figure is to bend the filter element before taking it out or installing it into the water purification device. Moreover, compared with the L-shaped bending method, the U-shaped bending design allows the operation to be completed in a smaller space, providing more operational flexibility and convenience.

[0044] Optionally, taking the filter element with 7 rotating joints as an example, the overall straightened length of the filter element is 413.9 mm; if the following is adopted Figure 4 The L-shaped bending method shown in the figure reduces the vertical height required for core replacement to 126.8 mm; if the Figure 5 With the U-bend shown, the vertical height required for core replacement is reduced to 105.1 mm.

[0045] In this way, even if the overall length of the filter element of the water purification device is relatively long and the water purification device is installed under the kitchen or in a place with limited vertical space, the user can easily remove the filter element from the water purification device or install it into the water purification device by bending the filter element.

[0046] In one embodiment, a bendable filter element is proposed, which reduces the space requirement around the water purification equipment when changing the filter element, making it easier for users to replace or install the filter element. At the same time, the filter element as a whole adopts a modular design, and each rotating joint is a consumable material, which can be disassembled and replaced according to actual needs. The structural parts that do not need to be replaced can be reused, which reduces resource waste and is more environmentally friendly.

[0047] In one embodiment, based on the above embodiment, referring to Figure 2 The filter element head also includes a silicone sleeve nested in the connection between the filter barrel cover and the upper shell.

[0048] In this embodiment, in order to increase the sealing when the upper shell is connected to the filter barrel cover, and to increase the firmness of the connection between the two, a silicone sleeve can be provided on the outside of the structural part of the filter barrel cover embedded in the upper shell; and the structural part of the filter barrel cover with the silicone sleeve can be inserted into the upper opening of the upper shell.

[0049] Optionally, the upper opening of the upper shell has a larger diameter than the lower opening of the upper shell, so that it is easier to locate the installation position of the lower shell and the filter barrel cover during the process of assembling the filter cartridge head.

[0050] Optionally, the connection port and the connector are detachably connected, wherein the detachable connection is a threaded connection or a snap-on connection, so that the assembly and disassembly of each rotating joint can be facilitated.

[0051] In an optional embodiment, the groove on the upper side of the central tube is a spherical groove, and its cross-sectional area is larger than that of the hemispherical groove. The groove has a certain toughness, and when the notch is squeezed by the ball head of the connector, it will produce a certain deformation to accommodate the ball head in the groove, and the ball head accommodated in the groove can not only rotate at a certain angle, but also is not easy to fall out of the groove.

[0052] Or, refer to Figure 3 The swivel joint also includes a ball cap for locking the ball head in the groove: the groove on the upper side of the central tube is a hemispherical groove, and can be combined with the corresponding ball cap to form a spherical groove with a larger cross-sectional area than the hemispherical groove, and the ball head in the groove is locked. When this groove is used, the ball cap of the connector is first placed in the groove, and then the ball cap is installed to fix the ball cap with the groove, thereby locking the ball head in the groove. This method can not only prevent the ball head from falling off, but also prevent the groove from being damaged due to excessive deformation.

[0053] Optionally, the ball cap and the outer wall of the groove may be connected by threaded connection, snap connection, ultrasonic welding, etc.

[0054] The utility model further proposes a water purification device, which includes a device body and a filter element. The specific structure of the filter element refers to the above embodiment, wherein a filter barrel for accommodating the filter element is provided in the device body, and the filter element is a bendable filter element as described in the above embodiment.

[0055] The filter element adopts all the technical solutions of all the above embodiments, and therefore has at least all the technical effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0056] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
