[0033] Specifically, the filter paper 14 can effectively filter out impurities and particles in the water to ensure the purity of the water quality. The identification rod 4 allows the user to easily identify the water pressure passing through the filter. The indicator plate 9 indicates the reading on the identification rod 4 by digging a groove 11. The observation tube 3 allows the user to intuitively observe the working status of the filter and read the number on the identification rod 4. The spring 2 8 provides power for the reset of the sliding column 6. The function of the baffle 17 is to squeeze the spring 2 8 to move the sliding column 6 by impacting the water on the baffle 17, thereby judging the pressure of the water flowing through the inside of the filter.

[0034] Please see the attached Figure 3 - Attachment Figure 5, the quick-release device 2 includes a mounting block 202, the bottom of the mounting block 202 is fixedly connected to the outer wall of the observation tube 3, the front and rear outer walls of the mounting block 202 are provided with a slide groove 205, the inner wall of the slide groove 205 is slidably connected with a card bead 206, and the inward side of the card bead 206 is fixedly connected with a spring 207, the outer wall of the mounting block 202 is provided with a mounting tube 201, the inner wall of the mounting tube 201 is slidably connected to the outer wall of the mounting block 202, the front and rear outer walls of the mounting tube 201 are provided with a card groove 204, the upper middle side of the outer wall of the mounting tube 201 is provided with a thread 203, the outer wall of the card groove 204 is fixedly connected with a sealing ring 12, and the inner wall of the card groove 204 is slidably connected to the outer wall of the card bead 206;

[0035] Specifically, the sealing ring 12 is used to ensure that the sealing performance of the device can be maintained during the disassembly process, the spring 207 is used to ensure that the card bead 206 can move and reset, the slide groove 205 is used to lock with the card bead 206 for quick connection, and the mounting tube 201 is used to ensure that the mechanism can be quickly disassembled. The thread 203 on the outer wall of the mounting tube 201 enables it to be directly connected to the bottom of the nozzle, thereby improving the stability of the connection.

[0036] Please see the attached Figure 2 - Attachment Figure 4 , the bottom end of the tube body 1 is fixedly connected to the bottom plate 15, and multiple identification rods 4 are fixedly connected at the same horizontal height. The top of the mounting tube 201 is fixedly connected to the sealing ring 3 16, the inward end of the spring 1 207 is fixedly connected to the inner wall of the slide 205, and the inner wall of the tube body 1 is provided with a plurality of water outlet holes 18. The top of the spring 2 8 is fixedly connected to the inner wall of the hollow tube 10. The bottom of the observation tube 3 is fixedly connected to the sealing ring 2 13, and the inner wall of the groove 11 is slidably connected to the outer wall of the identification rod 4;

[0037] Specifically, multiple identification rods 4 are fixedly connected at the same horizontal height, which can ensure the consistency and accuracy of the identification. The sealing ring 16 is used to prevent liquid leakage, the water outlet 18 is used to introduce the liquid obtained after filtering by the filter paper 14 into the tube body 1, and the sealing ring 13 is used to prevent liquid leakage in the observation tube 3. The sliding of the groove 11 and the identification rod 4 enables the indicator plate 9 to indicate the value on the identification rod 4.

[0038] Working principle: When using the filter, first turn on the water so that the water passes through the filter paper 14 and then flows into the tube body 1 through the water outlet 18. Then, press the baffle 17 upwards, so that it can move upward along the hollow tube 10 and compress the spring 2 8. At the same time, the connecting rod 5 moves upward together, driving the marking rod 4 to move upward so that the marking rod 4 is moved out of the groove 11. The number on the marking rod 4 indicated by the indicator plate 9 is read through the transparent observation tube 3 to understand the water pressure after filtering through the filter and judge whether the filter element is dirty and needs to be replaced.

[0039] When installation is required, screw the thread 203 into the nozzle. When the filter element needs to be replaced, press the beads 206 on both sides into the slide groove 205, thereby squeezing the spring 1 207 until the beads 206 are retracted into the slide groove 205. Then, pull the mounting tube 201 upward to replace the mounting block 202 and the fixed part below it. After the replacement is completed, just insert the mounting block 202 into the mounting tube 201. The chamfers around it fit the round shape of the beads 206, so that the beads 206 retract until they fit into the slot 204 and are then ejected and locked by the spring 1 207.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
