[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a water purifier with convenient filter replacement, comprising a water purifier body 1. The water purifier body 1 filters various impurities in the water step by step through a combination of multi-stage filter elements. A filter element cover 3 is threadedly connected to the upper side of the water purifier body 1, and a thread is provided on the lower side of the filter element cover 3. The filter element cover 3 is threadedly connected to the water purifier body 1. The filter element cover 3 is designed to close the upper opening of the water purifier body 1, allowing the filter element to be installed inside the water purifier body 1. The filter element cover 3 provides support for the sliding of the pressure block 2 and for the movement of the extension rod 11. A spring 8 is used to maintain the upper inner wall of the water purifier body 1. A rotating plate 13 is connected to the pressure block 2. The outer wall of the rotating plate 13 is rotatably connected to the lower inner wall of the pressure block 2. The rotating plate 13 serves as a connector, allowing the spring 8 and the pressure block 2 to connect. During the rotation of the pressure block 2, the rotating plate 13 prevents the spring 8 from twisting or deforming. One end of the spring 8 is fixedly connected to the upper inner wall of the filter cover 3, and the other end is fixedly connected to the lower outer wall of the rotating plate 13. The pressure block 2 is rotatably connected to the outer wall of the rotating plate 13. The pressure block 2 is cylindrical. When the pressure block 2 moves downward, it compresses the spring 8. The downward movement of the pressure block 2 presses the inclined surface of the extension rod 11, causing the extension rod 11 to move outward under pressure, thus driving the slide plate 9 to... The pressure block 2 moves outward, compressing spring 10. As the pressure block 2 moves back to its original position, the elastic force of spring 10 drives the extension rod 11 inward via the sliding plate 9, retracting the extension rod 11. The outer wall of the pressure block 2 slides on the upper inner wall of the filter cover 3. A limiting groove 7 is provided on the inner wall of the pressure block 2, guiding its sliding. A fixing block 12 is fixedly connected to the inner wall of the filter cover 3, with its outer wall sliding on the inner wall of the limiting groove 7, ensuring the pressure block 2 can only move along the limiting groove 7. A sliding plate 9 is elastically connected to the inner wall of the filter cover 3 via spring 10, serving as a connector between spring 10 and the extension rod 11. The outer wall of the rod 11 and the slide plate 9 are slidably connected to the inner wall of the filter cover 3. The slide plate 9 is rectangular. One end of the second spring 10 is fixedly connected to the inner wall of the filter cover 3, and the other end of the second spring 10 is fixedly connected to the outer wall of the slide plate 9. An extension rod 11 is fixedly connected to the lower outer wall of the slide plate 9. The extension rod 11 moves outward when squeezed, which facilitates the rotation of the filter cover 3 through the extension rod 11. No additional tools are needed to open the filter cover 3. The left outer wall of the extension rod 11 is inclined. The outer wall of the extension rod 11 is slidably connected to the inner wall of the filter cover 3. A placement component is provided on the upper side of the water purifier body 1. The placement component is used to place the filter cover 3.

[0032] Reference Figure 1 and Figure 2The placement component includes a movable plate 5, which is made of metal. The upper and lower sides of the movable plate 5 are provided with grooves that are compatible with magnetic strips 6. The movable plate 5 is fixed by the magnetic attraction of the magnetic strips 6. The outer wall of the movable plate 5 is slidably connected to the upper inner wall of the water purifier body 1. A placement rack 4 is fixedly connected to the upper outer wall of the movable plate 5. The placement rack 4 has three circular grooves that are compatible with filter cover 3 for placing the unscrewed filter cover 3. The height of the placement rack 4 is adjusted by moving the movable plate 5. A magnetic strip 6 is fixedly connected to the front inner wall of the water purifier body 1. The magnetic strip 6 magnetically attracts the movable plate 5 and fixes the position of the movable plate 5. There are two magnetic strips 6, which are symmetrically arranged.

[0033] Working principle: Move the moving plate 5 upward so that it magnetically attracts the upper magnetic strip 6, creating a gap between the placement rack 4 and the upper outer wall of the water purifier body 1. Rotate the pressure block 2 to position the fixing block 12 in the vertical groove of the limiting groove 7. Press the pressure block 2 downward to move it downward. When the pressure block 2 moves downward, it drives the rotating plate 13 to compress the spring 8. The pressure block 2 moves downward and squeezes the inclined surface of the extension rod 11. The extension rod 11 is squeezed and moves outward, driving the sliding plate 9 to move outward. Then rotate the pressure block 2 to position the fixing block 12 in the horizontal groove of the limiting groove 7 to fix the position of the extension rod 11. The extension rod 11 can then drive the rotation of the filter cover 3 to open the upper opening of the water purifier body 1. The unscrewed filter cover 3 can be placed in the circular groove of the placement rack 4, and then the filter can be replaced. After replacement, screw on the filter cover 3 and move the pressure block 2 in the opposite direction to release the pressure on the extension rod 11. Under the elastic force of the spring 10, the extension rod 11 retracts for easy storage.
