[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model provides a high-efficiency double-layer water filter, including a filter body 1, a delivery pipe 2 is fixedly connected between the two filter bodies 1, the top of the filter body 1 is fixedly connected to a disassembly component 3 by bolts, and the disassembly component 3 includes a positioning tube 31, a positioning block 33 and a filter element 34, the lower surface of the positioning block 33 is fixedly connected to the top of the filter element 34, an annular groove 39 is provided at the intersection of the positioning block 33 and the filter element 34, a receiving groove 311 is provided on the top of the positioning tube 31, the positioning block 33 is located inside the receiving groove 311, the filter element 34 is inserted into the interior of the positioning tube 31, and one end of the filter element 34 is located in the through Inside the filter body 1, a movable ring 37 is rotatably installed on the inner wall of the positioning tube 31, and a hollow tube 36 is slidably connected to the inner wall of the movable ring 37. The top of the hollow tube 36 is fixedly connected to a docking block 35, and the filter element 34 is inserted into the interior of the hollow tube 36. A first inclined groove 316 is provided on the inner wall of the hollow tube 36, and one end of the first inclined groove 316 is fixedly connected to the second inclined groove 317. A connector 312 is fixedly installed inside the hollow tube 36, and the connector 312 is located inside the first inclined groove 316. The interior of the docking block 35 is connected to a block 315 through a spring, and the bottom of the hollow tube 36 is fixedly connected to a tension spring 310.

[0025] The following describes in detail the specific configuration and function of this embodiment. The filter element 34 is built into the disassembly component 3, plugged into the interior of the filter body 1 and connected to the delivery pipe 2. When in use, water enters the filter element 34 from the delivery pipe 2, is filtered, and then output from the bottom of the filter body 1.

[0026] The positioning tube 31 is connected to the filter body 1. A receiving groove 311 is provided inside the positioning tube 31 to accommodate the positioning block 33. The top of the filter element 34 is connected to the positioning block 33 for quick and easy removal. The height of the filter element 34 can be adjusted by pressing the positioning block 33. The inclination of the first chute 316 is greater than that of the second chute 317.

[0027] When the connector 312 is in the second inclined groove 317, the docking block 35 is in the second cavity 38. Under the extrusion of the positioning tube 31, one end of the block 315 will be stuck in the annular groove 39, which plays a role in limiting the filter element 34. When disassembly is required, it is only necessary to press down the positioning block 33 to push the connector 312 into the first inclined groove 316. Then, under the rebound of the tension spring 310, the positioning block 33 will be bounced upward through the hollow tube 36, so that the docking block 35 re-enters the accommodating groove 311. At this time, the block 315 will pop out of the annular groove 39 to release the positioning block 33, and then the filter element 34 can be removed normally. The filter element 34 is a double-layer filtering structure. This is the existing technology and will not be described in detail here.

[0028] Example 2: Figure 2 、 Figure 3 and Figure 4 As shown, the other end of the tension spring 310 is fixedly connected to the positioning base 32, and the positioning base 32 is fixedly connected to the positioning tube 31. A first cavity 314 is opened on the inner wall of the positioning base 32, and the movable ring 37 is overlapped on the top of the positioning base 32. A second cavity 38 is opened on the inner wall of the positioning tube 31, and a partition plate 313 is fixedly installed on the bottom of the second cavity 38.

[0029] The effect achieved by the entire embodiment is that the positioning tube 31 is fixedly connected to the positioning base 32 and is installed at the bottom of the filter body 1. A first cavity 314 is defined on the inner wall of the positioning base 32 to accommodate the hollow tube 36. One end of the tension spring 310 is fixedly connected to the bottom of the first cavity 314. The second cavity 38 is used to accommodate the docking block 35. The diameter of the second cavity 38 is smaller than the diameter of the accommodating groove 311, thereby achieving the effect of squeezing the block 315.

[0030] The presence of the partition plate 313 can determine the position of the movable ring 37. When the positioning block 33 is pressed to push the filter element 34, the positioning block 33 will drive the docking block 35 to move downward together, thereby pushing the connector 312 on the hollow tube 36 into the first inclined groove 316 or the second inclined groove 317. During this process, the movable ring 37 will rotate to allow the connector 312 to enter the first inclined groove 316 or the second inclined groove 317. The partition plate 313 can determine the position of the movable ring 37.

[0031] The device is used in accordance with its working principle. The filter element 34 is fixedly connected to the positioning block 33 and is built into the disassembly assembly 3. When in use, the filter element 34 is inserted into the interior of the filter body 1 and is connected to the delivery pipe 2. When in use, water enters the filter element 34 from the delivery pipe 2, is filtered, and then is discharged from the bottom of the filter body 1.

[0032] When installing the filter element 34, the connector 312 on the hollow tube 36 is pushed into the second chute 317 by pressing the positioning block 33. The movable ring 37 rotates to allow the connector 312 to enter the first chute 316, so that the filter element 34 stays at a lower height and can be connected with the delivery pipe 2. When the connector 312 is in the second chute 317, the docking block 35 is in the second cavity 38. Under the pressure of the positioning tube 31, one end of the clamping block 315 is stuck in the annular groove 39, which plays a role in limiting the filter element 34. The diameter of the second cavity 38 is smaller than the diameter of the accommodating groove 311, which can achieve the effect of squeezing the clamping block 315.

[0033] When disassembly is required, the positioning block 33 is pressed down again to push the connector 312 into the first inclined groove 316. The movable ring 37 will rotate to allow the connector 312 to enter the second inclined groove 317. Since the inclination angle of the second inclined groove 317 is greater than that of the first inclined groove 316, the hollow tube 36 can move up a greater distance. Under the rebound of the tension spring 310, the positioning block 33 will be bounced upward through the hollow tube 36, allowing the docking block 35 to re-enter the accommodating groove 311. At this time, the blocking block 315 will pop out from the annular groove 39 to release the positioning block 33, and then the filter element 34 can be removed normally.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
