[0056] The following will take a preferred embodiment, and combine the drawings to more clearly and completely explain the present application.

[0057] As Figures 1 to 5As shown, the embodiment provides a filter core device 100, which comprises a cover plate 1, a filter core body 2 and a pushing assembly 3. The outer surface of the filter core body 2 is provided with a first matching part 21. The cover plate 1 is sleeved on the filter core body 2, and the surface of the cover plate 1 facing the filter core body 2 is provided with a second matching part 11, which is used to switch the locking state and the unlocking state of the filter core device 100. In the unlocking state, the first matching part 21 abuts against the second matching part 11 in the direction in which the filter core body 2 is separated from the cover plate 1. In the unlocking state, the first matching part 21 and the second matching part 11 are staggered in the direction in which the filter core body 2 is separated from the cover plate 1, and the filter core body 2 is separated from the cover plate 1.

[0058] As shown, Figures 1 to 3 The pushing assembly 3 comprises a push rod 31 and a rotating part 32. The push rod 31 is connected with the cover plate 1. One end of the rotating part 32 is rotationally connected with the filter core body 2, and the other end of the rotating part 32 is connected with one end of the push rod 31 away from the cover plate 1. The push rod 31 is used to apply a tangential force to the cover plate 1 to switch the locking state and the unlocking state. The moving path of the push rod 31 is parallel to one of the radial directions on the rotating path of the rotating part 32. By the interaction between the first matching part 21 and the second matching part 11 between the cover plate 1 and the filter core body 2, the switching of the locking state and the unlocking state of the filter core device 100 is realized, thereby not only improving the stability and reliability of the filter core device 100, but also facilitating the user to quickly replace the filter core body 2 and reducing the maintenance time and labor intensity. Specifically, when in the locking state, the first matching part 21 and the second matching part 11 abut against each other, ensuring the stable connection of the filter core body 2 and preventing the filter core body 2 from loosening due to water flow impact or other external forces, thereby ensuring the normal operation of the filter core device 100. When the filter core body 2 needs to be replaced, the user only needs to push the pushing assembly 3 to switch to the unlocking state. At this time, the first matching part 21 and the second matching part 11 are staggered with each other, the constraint between the filter core body 2 and the cover plate 1 is contacted, and the user can directly take out the filter core body 2 from the cover plate 1, thereby saving the process of replacing the filter core. In addition, the moving path of the push rod 31 is parallel to one of the radial directions on the rotating path of the rotating part 32, so that the rotating part 32 can push the push rod 31 to move during the rotating process, thereby realizing the rotation of the cover plate 1 relative to the filter core body 2 through the push rod 31 to switch the locking state and the unlocking state.

[0059] It needs to be specifically explained that in the embodiment, the first matching part 21 and the second matching part 11 are both in block shape, and in other embodiments, the first matching part 21 and the second matching part 11 can also be in other forms, which are not limited herein.

[0060] In addition, as shown, Figure 2 and Figure 4As shown, the number of the first matching pieces 21 is multiple, the multiple first matching pieces 21 are arranged around the outer surface of the filter core body 2 in a circumferential direction, and the second matching pieces 11 correspond to the first matching pieces 21 one by one. With the above structure, the connection area of the cover plate 1 and the filter core body 2 is increased, and the stability and reliability of the connection of the cover plate 1 and the filter core body 2 are improved. Specifically, taking the case where the axis of the filter core body 2 is placed in a vertical direction as an example, when the cover plate 1 is rotated in a direction in which the filter core body 2 is separated from the cover plate 1, the second matching piece 11 is located below the first matching piece 21, so that the second matching piece 11 can limit the movement of the first matching piece 21, thereby preventing the filter core body 2 from being separated from the cover plate 1, and at this time, the filter core device 100 is in a locked state; when the first matching piece 21 is located above the adjacent two second matching pieces 11 in the direction in which the filter core body 2 is separated from the cover plate 1, the first matching piece 21 and the second matching piece 11 are staggered, and at this time, the filter core body 2 can be separated from the cover plate 1.

[0061] In specific use, the moving path of the push rod 31 coincides with one of the radial directions on the rotating path of the rotating piece 32. With the above structure, the stroke of the rotating piece 32 in the rotating process for pushing the push rod 31 is improved.

[0062] In the embodiment, the direction in which the filter core body 2 is separated from the cover plate 1 is a vertical direction, and in other embodiments, the opposite direction of the direction in which the filter core body 2 is separated from the cover plate 1 can be adjusted according to actual needs, which is not limited herein.

[0063] As shown in Figure 3 The pushing assembly 3 further includes an abutting table 33, one end of the abutting table 33 is connected with the end of the push rod 31 away from the cover plate 1, the other end of the abutting table 33 extends towards the direction close to the rotating piece 32, and the abutting table 33 is used for abutting with the rotating piece 32. With the above structure, when the rotating piece 32 rotates, the rotation of the rotating piece 32 can be transmitted to the push rod 31 through the abutting table 33, so that the cover plate 1 is driven to rotate relative to the filter core body 2 through the push rod 31.

[0064] In specific use, the abutting table 33 has a certain extension length in the direction perpendicular to the moving path of the push rod 31, thereby reducing the possibility that the rotating piece 32 is separated from the abutting table 33 in the rotating process, and being conducive to improving the stability and reliability of the connection between the abutting table 33 and the rotating piece.

[0065] As shown in Figure 1 and Figure 2 The outer surface of the filter core body 2 is connected with multiple fixing pieces 4, each fixing piece 4 and the outer surface of the filter core body 2 enclose a containing cavity 41, the multiple containing cavities 41 are connected in communication along the moving direction of the pushing assembly 3, and each containing cavity 41 is in sliding connection with the pushing assembly 3. With the above structure, the containing cavities 41 can provide guidance for the movement of the filter core body 2, and the stability and reliability of the movement of the pushing assembly 3 are improved.

[0066] The number of the fixing members 4 is two in this embodiment, and the number of the fixing members 4 can be adjusted according to actual needs in other embodiments, which is not limited herein.

[0067] The surface of the accommodating cavity 41 facing the push rod 31 and the push rod 31 are provided with the sliding block 5 and the guide rail 6 which is in sliding cooperation with the sliding block 5, and the extension direction of the guide rail 6 is along the movement direction of the push rod 31. By using the above structure, the push rod 31 can move along the preset path through the cooperation of the sliding block 5 and the guide rail 6, thereby improving the stability and reliability of the movement of the push rod 31.

[0068] In this embodiment, the surface of the accommodating cavity 41 is provided with the sliding block 5, and the guide rail 6 is provided on the push rod 31. In other embodiments, the surface of the accommodating cavity 41 facing the push rod 31 can also be provided with the guide rail 6, and the push rod 31 is connected with the sliding block 5.

[0069] As shown in Figures 1 to 4 The filter element device 100 further comprises a connecting member 7, one end of the connecting member 7 is connected with the cover plate 1, and the other end of the connecting member 7 extends away from the cover plate 1 and is used to be connected with the pushing assembly 3. By using the above structure, the connecting member 7 is used to connect the pushing assembly 3 with the cover plate 1, so that the pushing assembly 3 can apply a tangential force to the cover plate 1 through the connecting member 7, the cover plate 1 can rotate relative to the filter element body 2, and the switching between the locked state and the unlocked state is realized.

[0070] It needs to be specifically pointed out that, in this embodiment, the extension direction of the connecting member 7 is the same as one of the radial directions of the cover plate 1, the extension direction of the pushing assembly 3 is parallel to the axis direction of the filter element body 2, and the surface of the pushing assembly 3 in contact with the filter element body 2 is an inclined surface. Therefore, the movement of the pushing assembly 3 along the axis direction of the filter element body 2 is converted into the movement along the tangential direction of the cover plate 1 through the inclined surface, so as to apply a tangential force to the cover plate 1, thereby making the cover plate 1 rotate relative to the filter element body 2 to realize the switching between the locked state and the unlocked state, which is beneficial to improve the compactness of the structure of the filter element device 100.

[0071] As shown in Figures 1 to 4 The cover plate 1 comprises a fixing seat 12, a cover plate body 13 and a rotating disc 14, the fixing seat 12 is connected with the cover plate body 13, and an accommodating cavity for placing the rotating disc 14 is formed between the fixing seat 12 and the cover plate body 13, and the second matching member 11 is arranged on the surface of the rotating disc 14 facing the filter element body 2. By using the above structure, the rotating disc 14 can be protected through the accommodating cavity formed between the fixing member 4 and the cover plate body 13, thereby improving the service life of the rotating disc 14.

[0072] In the embodiment, a surface of one of the fixing seat 12 and the cover plate body 13 is provided with a through hole 15 communicated with the accommodating cavity, so that one end of the connecting piece 7 can be connected with the rotating disc 14, and the other end of the connecting piece 7 extends from the through hole 15 and cooperates with the pushing assembly 3.

[0073] In addition, it should be noted that the cover plate 1 further comprises a spring 8, the operator rotates the rotating piece 32, and when the cover plate 1 is rotated to the locking position, the spring 8 is compressed; when the operator finishes replacing the filter element, the rotating piece 32 can be released, and under the driving of the spring 8, the cover plate 1 is rotated to the unlocking position, and in the rotating process, the cover plate 1 pushes the push rod 31 to return to the initial position through the connecting piece 7.
