[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1-8 As shown, a multi-stage combined filter includes a tank 1, an inlet 2 fixedly connected to the outside of the tank 1, a connecting pipe 3 fixedly connected to the outside of the tank 1, a tank 4 at the other end of the connecting pipe 3, a drain outlet 5 fixedly connected to the outside of the tank 4, a cover plate 6 on the top of the tank 1, an installation ring 7 fixedly connected to the outside of the cover plate 6, a fixing ring 8 fixedly connected to the top of the tank 1, an installation mechanism 9 between the installation ring 7 and the fixing ring 8, a clamping plate 10 fixedly connected inside the tank 1, multiple filter tubes 11 clamped inside the clamping plate 10, a cover door 12 on the top of the filter tubes 11, and a disassembly mechanism 13 on the outside of the cover door 12.

[0030] The mounting mechanism 9 includes a slider 90, a slide groove 91, and a housing 92. The slider 90 is fixedly connected to the outside of the mounting ring 7. The slide groove 91 is opened on the outside of the fixed ring 8. The housing 92 is fixedly connected to the outside of the fixed ring 8. A knob 93 is rotatably connected to the outside of the housing 92. A gear 94 is fixedly connected to the outside of the knob 93. A guide rod 95 is fixedly connected inside the housing 92. A spring 96 is sleeved on the outer periphery of the guide rod 95. A rack 97 is slidably connected to the outside of the guide rod 95.

[0031] It should be noted that when installing the cover plate 6, first turn the knob 93. The knob 93 drives the gear 94 to rotate. The gear 94 meshes with the rack 97, causing the rack 97 to slide along the guide rod 95 into the housing 92. At the same time, the spring 96 is compressed, and the spring 96 generates elastic force. After the rack 97 slides out from the slide groove 91, align the two sliders 90 with the slide groove 91. Then turn the cover plate 6 to move the sliders 90 to the end of the slide groove 91. Release the knob 93, and the spring 96 pushes the rack 97 out from the housing 92 and locks it into the slider 90 to lock and fix the cover plate 6.

[0032] The easy-to-disassemble mechanism 13 includes a fixing block 130 and a housing 131. The fixing block 130 is fixedly connected to the outside of the cover door 12, and the housing 131 is fixedly connected to the outside of the filter tube 11. A connecting rod 132 is slidably connected inside the housing 131. A spring 133 is sleeved on the outer periphery of the connecting rod 132. A moving block 134 is fixedly connected to one end of the connecting rod 132. Two insert blocks 135 are fixedly connected to the outside of the moving block 134.

[0033] It should be noted that when the filter media inside the filter tube 11 needs to be replaced, pull the connecting rod 132. The connecting rod 132 drives the moving block 134 to slide inside the outer shell 92, compressing the second spring 133. The second spring 133 generates elastic force, and the moving block 134 drives the insert block 135 to slide out from inside the fixed block 130 during the movement. At this time, the cover door 12 can be removed to replace the filter media inside the filter tube 11. When installing the cover door 12, pull the connecting rod 132 to let the insert block 135 enter the outer shell 131, and then close the cover door 12 to cover the filter tube 11. After releasing the connecting rod 132, the second spring 133 pushes the moving block 134 to drive the insert block 135 to fix the fixed block 130 and lock the cover door 12.

[0034] like Figure 2-5 As shown, the outer side of the slider 90 is slidably connected to the inside of the slide groove 91, and the gear 94 and the rack 97 mesh with each other.

[0035] It should be noted that the cooperation between the slider 90 and the groove 91 provides guidance for the installation of the cover plate 6, ensuring that the mounting ring 7 and the fixing ring 8 are precisely aligned. The gear 94 and the rack 97 mesh and drive each other. The extension and retraction of the rack 97 can be quickly controlled by rotating the knob 93, so as to fix and unlock the cover plate 6.

[0036] like Figure 5 As shown, one end of spring 96 is fixedly connected to the inside of housing 92, and the other end of spring 96 is fixedly connected to the outside of rack 97.

[0037] It should be noted that the spring 96 can be compressed by the rack 97 to generate elastic force to assist the rack 97 in resetting. In its natural state, the rack 97 can be stably engaged inside the slider 90.

[0038] like Figure 2-5 As shown, the rack 97 is slidably connected to the inside of the housing 92 on the outside. The rack 97 passes through the fixing ring 8 and is snapped into the inside of the slider 90. The slider 90 has a slot that matches the rack 97.

[0039] It should be noted that the outer shell 92 provides a sliding guide for the rack 97, ensuring that the rack 97 does not deviate during the extension and retraction process. The rack 97 passes through the fixing ring 8 and is inserted into the slot of the slider 90 to form a double fixing structure, which further improves the connection stability between the cover plate 6 and the tank body 1. The matching design of the slot and the rack 97 ensures a tight connection and avoids water leakage.

[0040] like Figure 8 As shown, the outer side of the movable block 134 is slidably connected to the inside of the housing 131, and the other end of the connecting rod 132 is fixedly connected to the pull block 136.

[0041] It should be noted that the movable block 134 slides in the groove of the housing 131 to provide guidance for the extension and retraction of the insertion block 135. The pull block 136 allows the operator to unlock the insertion block 135 by pulling the pull block 136 to move the connecting rod 132 and the movable block 134.

[0042] like Figure 8 As shown, one end of spring 133 is fixedly connected to the inside of housing 131, and the other end of spring 133 is fixedly connected to the outside of moving block 134.

[0043] It should be noted that the second spring 133 can be compressed by the moving block 134 to generate elastic force to assist the insertion block 135 in resetting. In its natural state, it can keep the insertion block 135 stably locked inside the fixed block 130.

[0044] like Figure 8 As shown, the outer side of the insert 135 is slidably connected to the inside of the housing 131, and the outer side of the insert 135 is slidably connected to the inside of the fixing block 130.

[0045] It should be noted that the outer side of the insert 135 is slidably connected to the inside of the housing 131, so that the insert 135 can extend and retract. The outer side of the insert 135 is slidably connected to the inside of the fixing block 130, so that the insert 135 can fix the fixing block 130.

[0046] The working principle of this utility model is as follows: Tank 1 and Tank 2 have the same structure and are combined in multiple sections through the connecting pipe 3. First, the filter tube 11 filled with filter media is inserted into the clamping plate 10 inside Tank 1 and Tank 2, and then the cover plate 6 is installed. First, the knob 93 is turned, which drives the gear 94 to rotate. The gear 94 meshes with the rack 97, causing the rack 97 to slide along the guide rod 95 into the outer shell 92. At the same time, the spring 96 is compressed, and the spring 96 generates elastic force. After the rack 97 slides out from the slide groove 91, the two sliders 90 are aligned with the slide groove 91. Then, the cover plate 6 is turned, causing the sliders 90 to move to the end of the slide groove 91. The knob 93 is released, and the spring 96 pushes the rack 97 out from the outer shell 92, where it is clamped inside the slider 90 to lock and fix the cover plate 6. Then, the inlet 2 is connected to an external water source, allowing the water to be purified to enter Tank 1. The filter undergoes initial internal purification, then enters the second tank 4 through the connecting pipe 3 for secondary purification, and finally discharges through the drain outlet 5. The drain outlet 5 can be connected to other water storage devices for recycling. When the filter material inside the filter tube 11 needs to be replaced, pull the connecting rod 132. The connecting rod 132 drives the moving block 134 to slide inside the outer shell 92, compressing the second spring 133. The second spring 133 generates elastic force, and the moving block 134 drives the insert block 135 to slide out from inside the fixed block 130 during the movement. At this time, the cover door 12 can be removed to replace the filter material inside the filter tube 11. When installing the cover door 12, pull the connecting rod 132 to let the insert block 135 enter the shell 131, and then close the cover door 12 to cover the filter tube 11. After releasing the connecting rod 132, the second spring 133 pushes the moving block 134 to drive the insert block 135 to fix the fixed block 130 and lock the cover door 12.
