[0069] Framework 111 DETAILED DESCRIPTION

[0070] The utility model will be described below in a preferred embodiment, and in combination with drawings more clearly and completely.

[0071] As Figures 1 to 7As shown, the embodiment provides a filter core device 100, which comprises a rotating disc 1, a filter core body 2, a first elastic member 3 and a second elastic member 4. The rotating disc 1 is sleeved on the filter core body 2. One of the rotating disc 1 and the filter core body 2 is provided with an accommodating groove 22 with an opening 23. The first elastic member 3 is arranged in the accommodating groove 22. The other of the rotating disc 1 and the filter core body 2 is connected with an abutting member 5. The abutting member 5 extends into the accommodating groove 22 from the opening 23 and is used for cooperating with the first elastic member 3. The rotating disc 1 is provided with a first channel 14. The filter core body 2 is provided with a second channel 21. The second elastic member 4 is arranged in the first channel 14. The rotating disc 1 rotates circumferentially around the filter core body 2 and is used for switching the state of the filter core device 100. In the first state, the abutting member 5 is compressed by the first elastic member 3 in the movement direction of the rotating disc 1. The second channel 21 extends into the first channel 14 to compress the second elastic member 4. The first channel 14 and the second channel 21 are communicated to enable water to flow from the rotating disc 1 into the filter core body 2. In the second state, the rotating disc 1 rotates relative to the filter core body 2 under the elastic force of the first elastic member 3. The filter core body 2 is separated from the rotating disc 1. The second channel 21 is separated from the first channel 14 under the elastic force of the second elastic member 4. By adopting the above structure, the filter core device 100 realizes the switching of the two states through the rotation of the rotating disc 1 and the filter core body 2. In the first state, the abutting member 5 is compressed by the first elastic member 3. The second channel 21 extends into the first channel 14 to compress the second elastic member 4. The first channel 14 and the second channel 21 are communicated to enable water to flow from the rotating disc 1 into the filter core body 2, thereby effectively guaranteeing the normal filtering function of the filter core. In the second state, the rotating disc 1 rotates relative to the filter core body 2 under the elastic force of the first elastic member 3. The filter core body 2 is separated from the rotating disc 1. The elastic force of the second elastic member 4 enables the second channel 21 to be separated from the first channel 14, thereby facilitating the installation and replacement of the filter core.

[0072] It should be particularly pointed out that, as shown, Figure 3 The opening 23 of the accommodating groove 22 faces the abutting member 5, thereby facilitating the abutting member 5 to extend into the accommodating groove 22 to cooperate with the first elastic member 3. In the first state, the two ends of the first elastic member 3 respectively abut against the abutting member 5 and the wall surface of the accommodating groove 22 under the action of the abutting member 5. Therefore, the first elastic member 3 can be compressed by the abutting member 5 to store energy, thereby facilitating the abutting member 5 to provide power for the rotating disc 1 to return to the initial position in the second state. Similarly, in the first state, the two ends of the second elastic member 4 respectively abut against the first channel 14 and the second channel 21 under the action of the first channel 14 and the second channel 21. At this time, the second elastic member 4 is in a compressed state to store energy, thereby facilitating the second elastic member 4 to provide power for the rotating disc 1 to be separated from the filter core body 2 in the second state.

[0073] In order to better store energy of the first elastic member 3 and the second elastic member 4 in the first state, preferably, the elastic force direction of the first elastic member 3 is the same as the direction of the rotation of the rotating disc 1 relative to the filter core body 2 in the circumferential direction; the elastic force direction of the second elastic member 4 is the same as the direction of the insertion of the second channel 21 into the first channel 14.

[0074] As shown in Figure 5 and Figure 6 , the outer surface of the filter core body 2 is provided with the first matching member 6, and the surface of the rotating disc 1 facing the filter core body 2 is provided with the second matching member 7; in the first state, in the direction of the filter core body 2 away from the rotating disc 1, the first matching member 6 abuts against the second matching member 7; in the second state, in the direction of the filter core body 2 away from the rotating disc 1, the first matching member 6 and the second matching member 7 are staggered. By using the above structure, the switching of the locking and unlocking states of the rotating disc 1 and the filter core body 2 is realized through the action of the first matching member 6 and the second matching member 7 between the rotating disc 1 and the filter core body 2. Specifically, in the first state, the water in the rotating disc 1 needs to flow into the filter core body 2 to filter the water through the filter core body 2, and the first matching member 6 and the second matching member 7 abut against each other, thereby realizing the stable connection of the filter core body 2 and the rotating disc 1, and ensuring the normal operation of the filter core device 100. In the second state, the filter core body 2 needs to be separated from the rotating disc 1, and at this time, the first matching member 6 and the second matching member 7 are staggered with each other, thereby facilitating the separation of the filter core body 2 from the rotating disc 1, and facilitating the replacement of the filter core body 2 in the later period.

[0075] It needs to be specifically explained that in the first state, the first matching member 6 abuts against the second matching member 7, so that the first matching member 6 can be limited by the second matching member 7, preventing the filter core body 2 from being separated from the rotating disc 1.

[0076] In the embodiment, the number of the first matching member 6 and the second matching member 7 is multiple, the multiple first matching members 6 are arranged in the circumferential direction around the outer surface of the filter core body 2, and the second matching member 7 is arranged corresponding to the first matching member 6. By using the above structure, the connection area of the rotating disc 1 and the filter core body 2 is increased, and the stability and reliability of the connection of the rotating disc 1 and the filter core body 2 are improved.

[0077] As shown in Figure 1 and Figure 2As shown, the filter element device 100 further comprises a pushing member 8, which is used to apply a tangential force to the rotating disc 1 to make the rotating disc 1 rotate relative to the filter element body 2 to switch between the first state and the second state. With the above structure, the pushing member 8 is used to apply a tangential force to the rotating disc 1 to make the rotating disc 1 rotate relative to the filter element body 2 to switch between the first state and the second state, which improves the operation convenience of the filter element device 100, and the user does not need to directly operate the rotating disc 1 complicatedly, but only needs to apply a corresponding force through the pushing member 8 to complete the state conversion. In actual use, when the filter element body 2 needs to be replaced or maintained, the pushing member 8 can ensure that the relative rotation between the rotating disc 1 and the filter element body 2 is more stable and reliable, effectively avoiding problems such as component damage or loose connection caused by improper manual operation.

[0078] As shown in Figure 2 and Figure 7 The pushing member 8 comprises a pushing rod 81, a fixed part 82 and an elastic part 83. The pushing rod 81 is used to apply a tangential force to the rotating disc 1. The fixed part 82 is connected with the filter element body 2. A receiving groove 811 is formed on the surface of the pushing rod 81 facing the fixed part 82. The elastic part 83 is arranged in the receiving groove 811. On the moving path of the pushing rod 81, a first abutting surface 8111 on the receiving groove 811 and a second abutting surface 821 on the fixed part 82 are respectively used to abut against both ends of the elastic part 83. With the above structure, the pushing rod 81 is used to apply a tangential force to the rotating disc 1, and the relative rotation between the rotating disc 1 and the filter element body 2 is realized by the movement of the pushing rod 81, thereby completing the switching between the first state and the second state. The receiving groove 811 is formed on the surface of the pushing rod 81 facing the fixed part 82, and the elastic part 83 is arranged in the receiving groove 811. On the moving path of the pushing rod 81, the first abutting surface 8111 on the receiving groove 811 and the second abutting surface 821 on the fixed part 82 are respectively abutted against both ends of the elastic part 83. The elastic part 83 can be elastically deformed when the pushing rod 81 moves, thereby providing assistance when the pushing rod 81 returns to the original position, and ensuring that the pushing rod 81 can accurately return to the original position.

[0079] It needs to be specifically explained that the fixed part 82 is connected with the filter element body 2, so that the fixed part 82 can be relatively fixed relative to the filter element body 2. At this time, the pushing rod 81 moves along the moving path relative to the filter element body 2, so that the pushing rod 81 moves relative to the fixed part 82. The elastic part 83 can be compressed when the pushing rod 81 moves, and the elastic part 83 can store energy in the first state, which is convenient for the pushing rod 81 to return to the original position under the action of the elastic part 83 in the second state.

[0080] One end of the pusher 8 is in abutment with the rotating disc 1, and the other end of the pusher 8 penetrates the filter element body 2 along the movement path of the pusher 8. With the above structure, the other end of the filter element body 2 can limit the pusher 8, so that the pusher 8 can be installed to move along a preset path, thereby improving the stability and reliability of the movement of the pusher 8, and thus improving the stability and reliability of the pusher 8 pushing the rotating disc 1 to rotate.

[0081] It should be specifically pointed out that, as shown in Figure 2 , the pusher 8 penetrates the skeleton 111 of the end of the filter element body 2 away from the rotating disc 1 along the movement path of the pusher 8.

[0082] As shown in Figure 4 and Figure 5 , the filter element device 100 further comprises a connecting piece 9, one end of the connecting piece 9 is connected with the rotating disc 1, and the other end of the connecting piece 9 extends away from the rotating disc 1, and is used for abutting with the pusher 8. With the above structure, the abutment of the rotating disc 1 and the pusher 8 is facilitated through the connecting piece 9.

[0083] The extension direction of the pusher 8 is parallel to the axis direction of the filter element body 2. With the above structure, it is beneficial to improve the compactness of the structure of the filter element device 100. In addition, in order to facilitate the rotating disc 1 moving along the circumferential direction of the filter element body 2 driven by the pusher 8, preferably, the pusher 8 further comprises a pushing part 85, and the pushing part 85 is connected with one end of the push rod 81 close to the connecting piece 9, and the surface of the pushing part 85 facing the connecting piece 9 is a bevel, so that when the pusher 8 moves along the axis direction of the filter element body 2, the rotating disc 1 is pushed to move along the circumferential direction of the filter element body 2 through the surface of the pushing part 85 facing the connecting piece 9.

[0084] It should be specifically pointed out that, as shown in Figure 1 and Figure 2 , in order to further improve the stability and reliability of the movement of the push rod 81, preferably, the pusher 8 further comprises a plurality of supporting parts 84, and the plurality of supporting parts 84 are connected to the outer surface of the filter element body 2, and the plurality of supporting parts 84 are arranged in the extension direction of the push rod 81. The surface of the supporting part 84 facing the push rod 81 is provided with a groove, and the push rod 81 is in sliding connection with the surface of the groove.

[0085] As shown in Figure 5As shown, the turntable 1 includes a fixed base 11, a turntable body 12, and a rotating component 13. The fixed base 11 is connected to the turntable body 12, and a cavity for placing the rotating component 13 is formed between the fixed base 11 and the turntable body 12. The rotating component 13 is sleeved on the filter element body 2. The turntable body 12 has a water passage for water flow, and the fixed base 11 has a first channel 14 communicating with the water passage. With this structure, the fixed base 11 is connected to the turntable body 12, forming a cavity for placing the rotating component 13. The rotating component 13 is sleeved on the filter element body 2, thus providing a stable installation position for the rotating component 13 and making the connection between the turntable 1 and the filter element body 2 more secure and reliable, effectively preventing loosening or detachment during use. The water passage on the turntable body 12 and the first channel 14 on the fixed base 11 ensure that water can flow smoothly from the turntable 1 into the filter element body 2, thereby filtering the water through the filter element body 2.

[0086] In practical use, the connecting member 9 is connected to the outer surface of the rotating member 13, preferably the connecting member 9 and the rotating member 13 are integrally formed. In other embodiments, the connecting member 9 and the rotating member 13 may also have other connection forms, which are not limited here.

[0087] In this embodiment, as Figure 1 and Figure 2 As shown, there are two filter element bodies 2. The turntable 1 is provided with two fixed seats 11 and two rotating parts 13, which are respectively matched with the two filter element bodies 2. In other embodiments, the number of filter element bodies 2 can be adjusted according to actual needs, and is not limited here. In addition, a handle 10 is provided on the filter element body 2 for easy handling by the operator.

[0088] This embodiment also provides a water purifier, which includes a filter cartridge device 100. Specifically, the filter cartridge device 100 is applied to the water purifier, adopting the above-described structural form. The filter cartridge device 100 achieves the switching between two states through the rotation of the turntable 1 and the filter cartridge body 2. In the first state, the abutment member 5 compresses the first elastic member 3, and the second channel 21 extends into the first channel 14 to compress the second elastic member 4. The first channel 14 and the second channel 21 are connected, allowing water to flow smoothly from the turntable 1 into the filter cartridge body 2, effectively ensuring the normal filtration function of the filter cartridge. In the second state, relying on the elastic force of the first elastic member 3, the turntable 1 rotates relative to the filter cartridge body 2, and the filter cartridge body 2 disengages from the turntable 1. At the same time, the elastic force of the second elastic member 4 causes the second channel 21 to disengage from the first channel 14. This not only facilitates the installation and replacement of the filter cartridge, but also effectively prevents accidental damage to the filter cartridge in the non-working state, extending its service life.
