[0023] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail a double-tooth buckle structure for a water purifier with reference to the drawings.

[0024] Such asFigures 1-4 As shown, the utility model is a double-tooth buckle structure for a water purifier, including a sleeve 1, a filter bottle cover 17 is sleeved inside the sleeve 1, a card frame 9 is welded inside the filter bottle cover 17, a movable rack 10 is sleeved inside the card frame 9, the surface of the movable rack 10 engages with a gear 7, a card slot 8 is provided inside the gear 7, a card block 6 is clamped inside the card slot 8, the top of the card block 6 is fixedly connected to the fixed rod 5, the other end of the fixed rod 5 is welded with a knob cover 4, one end of the movable rack 10 is fixedly connected to the limit block 12, and by installing the gear 7, the gear 7 can be used to control the extension and retraction of the movable rack 10 until the movable rack 10 Retract the card frame 9, and then you can directly take out the filter bottle cover 17, and then replace the filter element inside the sleeve 1. It is very convenient to use. The limit block 12 passes through the filter bottle cover 17 and the sleeve 1, and the other end of the movable rack 10 is clamped with the spring 11. The other end of the spring 11 fits into the card frame 9. By installing the spring 11, when the filter bottle cover 17 is embedded in the sleeve 1, the spring 11 can be used to push out the movable rack 10, so that the limit block 12 passes through the sleeve 1 and the filter bottle cover 17. At this time, the filter bottle cover 17 can be fixed inside the sleeve 1, which is very convenient to use.

[0025] There are two movable racks 10, which are distributed in opposite directions. The filter element cylinder 2 is sleeved inside the sleeve 1. The distribution form of the movable racks 10 can further provide a stabilizing effect after the filter bottle cover 17 is installed, and the stability is relatively strong during use.

[0026] The bottom of the knob cover 4 is fixedly connected to the snap ring 16, and the surface of the filter bottle cover 17 is sleeved with the decorative cover 15. The knob cover 4 is located inside the decorative cover 15, and the top of the snap ring 16 is attached to the inner wall of the decorative cover 15. By installing the snap ring 16, the snap ring 16 can be used to provide a position fixing effect for the knob cover 4 without affecting the rotation effect of the knob cover 4, which is very convenient to use.

[0027] A second limiting hole 14 is opened on the surface of the sleeve 1, and a first limiting hole 13 is opened on the surface of the filter bottle cover 17. The first limiting hole 13 is fitted to the second limiting hole 14. By fitting the first limiting hole 13 to the second limiting hole 14, it is more convenient for the limiting block 12 to pass through the first limiting hole 13 and the second limiting hole 14, which is very convenient to use.

[0028] The limit block 12 is located inside the first limit hole 13, and the limit block 12 is located inside the second limit hole 14. By installing the limit block 12 and utilizing the limit block 12 located in the first limit hole 13 and the second limit hole 14, the filter bottle cover 17 can be fixed inside the sleeve 1, and it is more stable when used.

[0029] The mounting plate 3 is welded to the bottom of the sleeve 1, the filter element cylinder 2 is located on the top of the mounting plate 3, and the filter element cylinder 2 is located at the bottom of the filter bottle cover 17. By installing the filter bottle cover 17, the filter element cylinder 2 can be limited inside the sleeve 1 using the filter bottle cover 17, so that the filter element sleeve 1 will not separate from the sleeve 1, which is very convenient to use.

[0030] Working principle of the double-tooth buckle structure for the water purifier: When using the double-tooth buckle structure for the water purifier, the filter element cylinder 2 should be first placed inside the sleeve 1. Then, the limit block 12 is pressed inward until the limit block 12 is inside the filter cap 17. After that, the filter cap 17 is inserted into the sleeve 1. Subsequently, the filter cap 17 is rotated until the limit block 12 is at the first limit hole 13 and the second limit hole 14. At this time, the limit block 12 will be pushed by the spring 11, so that the limit block 12 is inserted into the first limit hole 13 and the second limit hole 14 to fix the filter cap 17. Then, the double-tooth buckle structure for the water purifier can be used. When it is necessary to replace the filter element inside the sleeve 1, the sleeve 1 needs to be opened through the double-tooth buckle structure for the water purifier. At this time, hold the knob cap 4 with the hand and rotate the knob cap 4. At this time, the knob cap 4 will drive the clamping block 6 through the fixing rod 5. Since the clamping block 6 is clamped in the clamping groove 8, the clamping block 6 will drive the gear 7 to rotate, and then use the gear 7 to control the telescopic movement of the movable rack 10 until the movable rack 10 retracts into the clamping frame 9. Then, the filter cap 17 can be directly taken out. After that, the filter element inside the sleeve 1 is replaced, which is very convenient to use. When the replacement of the filter element cylinder 2 is completed, after the filter cap 17 is inserted into the sleeve 1, the spring 11 can be used to push out the movable rack 10, so that the limit block 12 penetrates through the sleeve 1 and the filter cap 17. At this time, the filter cap 17 can be fixed inside the sleeve 1, which is very convenient to use.

[0031] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
