Description

Technical Field

[0001] The utility model belongs to the field of filter element assemblies, and particularly relates to a filter element assembly with a push-type locking mechanism. Background Art

[0002] In order to improve the quality of domestic water, many families are equipped with water purifiers. A water purifier generally includes a filter element assembly and a machine body. The filter element assembly is installed in the machine body and docked with a water circuit board in the machine body, so that the filter element assembly can normally perform the filtering function. The filtering capacity of the filter element assembly will decrease with the increase of the use time. Therefore, generally, it needs to be replaced after being used for a period of time. The simplicity and convenience of the filter element fixing method become one of the important considerations for users when purchasing a water purifier. Based on this, generally, the filter element assembly and the machine body are detachably connected.

[0003] For example, the existing water purifier can adopt a buckle structure for filter element installation. That is, by means of pulling, pressing or pinching, etc., the buckle is separated from the water purifier to take out the filter element from the water purifier. However, this structure is sometimes restricted by the installation scenario of the water purifier and is not convenient for operation; and the internal linkage structure of the buckle is complex, and relatively large force is required for operation, and problems such as jamming are likely to occur inside.

[0004] Based on this, there is an urgent need for a new type of filter element assembly to facilitate the installation and disassembly of the filter element and the filter element seat. Summary of the Utility Model

[0005] Utility Model Objective: The technical problem to be solved by the utility model is to provide a filter element assembly that can facilitate the installation and disassembly of the filter element.

[0007] The locking mechanism includes a coaxial cylinder formed by splicing semi-cylinders respectively rotatably arranged on the filter element seat and the filter element. A push rod assembly extends from the semi-cylinder on the filter element. A semi-cylinder groove for accommodating the upper semi-cylinder on it is opened on the filter element seat. By driving the push rod assembly, the splicing surface of the coaxial cylinder and the end surface of the semi-cylinder groove are at different angles to realize the locking or unlocking between the filter element and the filter element seat.

[0008] Furthermore, a first groove for accommodating the semi-cylinder on the filter element and supporting the filter element is opened on the filter element seat of the filter element assembly, and the semi-cylinder groove extends downward from the bottom end surface of the first groove.

[0009] Furthermore, the push rod assembly of the filter element assembly includes a connecting rod provided on the filter element and a push rod connecting the two side connecting rods.

[0010] Furthermore, a second groove for limiting the rotation angle is provided on the filter element of the filter element assembly at the rotation position of the connecting rod. One end of the second groove is a vertical end face, and the other end is an inclined end face. And the second groove communicates with the semi-cylindrical groove on the filter element.

[0011] Furthermore, the semi-cylinder on the filter element seat of the filter element assembly is rotatably provided on the filter element seat through a connecting shaft.

[0012] Furthermore, the other end of the connecting shaft of the filter element assembly is connected with a rotating rod, and a reset tension spring is provided on the rotating rod. The other end of the tension spring is provided on the filter element seat.

[0013] Furthermore, a fixing rod for connecting the tension spring is extended on the filter element seat of the filter element assembly.

[0024] The technical solution of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] As Figure 1 shown, the filter element assembly of the present utility model includes a filter element seat 1 and a filter element 2 horizontally inserted into the filter element seat 1. A plurality of water ports are horizontally provided on the filter element 2. Correspondingly, through holes matching the plurality of water ports are provided on the filter element seat 1. A convex block 13 is extended and provided at the lower end of the filter element seat 1 corresponding to the plurality of through holes. A third groove 15 is provided on the filter element 2 corresponding to the convex block 13 to further support the filter element seat 1 in the locked state of the filter element 2 through the cooperation of the convex block 13 and the third groove 15.

[0026] The locking or unlocking state of the filter element 2 and the filter element seat 1 is realized through a push-type locking mechanism. And the two groups of locking mechanisms are symmetrically arranged, respectively located on both sides of the connection between the filter element 2 and the filter element seat 1. The locking mechanism includes a coaxial cylinder formed by splicing two semi-cylinders 3. One of the semi-cylinders 3 is rotatably arranged on the filter element seat 1. Correspondingly, a semi-cylindrical groove 4 for accommodating the semi-cylinder 3 is provided on the filter element seat 1 to realize its rotation in the semi-cylindrical groove 4. The other semi-cylinder 3 is rotatably arranged on the filter element 2. Similarly, a semi-cylindrical groove 4 for accommodating the semi-cylinder 3 is provided on the filter element 2 to realize its rotation in the semi-cylindrical groove 4. A first groove 5 for accommodating the semi-cylinder 3 on the filter element 2 and capable of supporting the installed filter element 2 is also provided on the filter element seat 1. And the semi-cylindrical groove 4 on the filter element seat 1 extends downward from the bottom end surface of the first groove 5, that is, the locking or unlocking state of the filter element 2 and the filter element seat 1 is determined by the relative position between the splicing surface of the coaxial cylinder formed by splicing the two semi-cylinders 3 and the end surface of the semi-cylindrical groove 4 on the filter element seat 1. When the splicing surface of the two semi-cylinders 3 and the end surface of the semi-cylindrical groove 4 are in the same horizontal plane, the filter element 2 and the filter element seat 1 are in the unlocked state at this time; when there is a certain angle between the splicing surface of the two semi-cylinders 3 and the end surface of the semi-cylindrical groove 4, the filter element 2 and the filter element seat 1 are in the locked state at this time.

[0027] The semi-cylinder 3 on the filter element seat 1 is rotatably arranged in the semi-cylindrical groove 4 of the filter element seat 1 through the connecting shaft 8. The rotating shaft 8 penetrates through the filter element seat 1 and is connected with a rotating rod 9 at the other end. The semi-cylinder 3 on the filter element 2 is rotatably arranged in the semi-cylindrical groove 4 of the filter element 2 through the connecting bolt 12. A push rod assembly composed of a connecting rod 6 and a push rod 7 connecting the two connecting rods 6 extends from the semi-cylinder 3 on the filter element 2. That is, the semi-cylinder 3 on the filter element 2 is pushed to rotate through the push rod assembly, and then the semi-cylinder 3 on the filter element seat 1 is driven to rotate, so as to make the mating surfaces of the two be at different angles. A corresponding second groove 14 is arranged on the filter element 2 corresponding to the rotation range of the connecting rod 6. One side end of the second groove 14 is a vertical end surface, and the other side end is an inclined end surface. And the second groove 14 communicates with the semi-cylindrical groove 4 on the filter element. For the specific setting of the inclination angle, the present invention does not make a limitation, and can be adaptively adjusted according to actual needs. That is, the rotation of the connecting rod 6 is limited by the second groove 14. When the connecting rod 6 moves to fit with the vertical end surface, at this time, the mating surface of the two semi-cylinders 3 is flush with the end surface of the semi-cylindrical groove 4 on the filter element seat 1, realizing the unlocking of the two. When the connecting rod 6 moves to the end of the inclined end surface, there is a certain angle between the mating surface of the two semi-cylinders 3 and the end surface of the semi-cylindrical groove 4 on the filter element seat 1, realizing the locking of the two. And in this state, the position of the locking state of the two is maintained by a tension spring 10 with one end connected to the rotating rod 9 and the other end connected to the filter element seat 1. That is, a through hole connected to the tension spring 10 is opened on the rotating rod 9, and a fixing rod 11 is also arranged on the filter element seat 1 between the through hole and the connecting shaft 8 to fix the other end of the tension spring 10.

[0028] The locking or unlocking state of the filter element 2 and the filter element seat 1 of the present utility model is determined by the position of the end surface formed by the mating of the two semi-cylinders 3 and the end surface of the semi-cylindrical groove 4. When there is a certain inclination angle between the end surface formed by the mating of the two semi-cylinders 3 and the end surface of the semi-cylindrical groove 4, at this time, under the pulling force of the tension spring 10, the push rod 7 is located at the inclined end surface of the groove, and the two are in a locked state, as Figure 6 shown. Push the push rod 7, that is, rotate the coaxial cylinder, and the tension spring 10 is stretched. When the connecting rod 6 rotates to the vertical end surface of the groove, the end surface formed by the mating of the two semi-cylinders 3 and the end surface of the semi-cylindrical groove 4 are located on the same horizontal plane. At this time, the filter element 2 and the filter element seat 1 are in an unlocked state, as Figure 7 shown.
