Description

Technical Field

[0001] This utility model belongs to the field of water purifier filter technology, and in particular relates to a high-efficiency water purifier filter replacement device. Background Technology

[0002] Water purifier filter cartridges are the core components of water purifiers. Their main function is to filter impurities in the water and ensure that the water quality reaches a certain level of cleanliness. There are various types of filter cartridges, each with its specific filtration effect and service life. Water purifier filter cartridges are divided into four types: microfiltration (also called coarse filtration), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO).

[0003] Water purifier filter cartridges can filter out various impurities in water during use. However, after prolonged use, the filter cartridges need to be replaced. But replacing existing water purifier filter cartridges is very inconvenient, requiring professional personnel to replace them, which increases the replacement cost for users. To address this issue, we provide a high-efficiency water purifier filter cartridge replacement device to solve the above problems. Utility Model Content

[0025] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-7 This utility model is a high-efficiency water purifier filter replacement device, including a bottle body 1 and a protective structure 4. A bottle cap 2 is sealed to the top of the bottle body 1. An inlet / outlet water pipe 3 is fixedly connected to the top of the bottle cap 2. A pressure relief valve 5 is connected to the front side of the top of the bottle cap 2. Three locking blocks 6 are fixedly connected to the bottom of the bottle cap 2. A locking strip 7 is engaged in the inner cavity of the locking block 6. The side of the locking strip 7 near the inner wall of the bottle body 1 is fixedly connected to the inner wall of the bottle body 1. A through hole 8 is opened on the right side of the bottom of the bottle cap 2 for inlet and outlet. The bottom of the water pipe 3 is connected to a connecting pipe 9, and a filter element 10 is snapped onto the surface of the connecting pipe 9. The top of the filter element 10 contacts the inner wall of the bottle cap 2, and the bottom of the filter element 10 contacts the inner wall of the bottle body 1. The protective structure 4 includes a housing 401. The bottom of the housing 401 is fixedly connected to the bottle cap 2. The inner cavity of the housing 401 is movably connected to a connecting block 402 through a shaft pin. A cover plate 403 is fixedly connected to the front side of the connecting block 402, and a lever 404 is fixedly connected to the front side of the cover plate 403.

[0028] Specifically: Water enters through the right side of the inlet / outlet pipe 3, passes through the through hole 8 into the inner cavity of the bottle body 1, and uses the principle of water pressure to filter impurities in the water. The filtered water then re-enters the inner cavity of the inlet / outlet pipe 3 through the connecting pipe 9, and is then discharged through the left side of the inlet / outlet pipe 3. When the user needs to replace the filter element 10, the user moves the lever 404 upward to separate the cover plate 403 from the housing 401. At this time, the user can press down the pressure relief valve 5 to reduce the pressure inside the bottle body 1. Then, the user can rotate the bottle cap 2 to separate the locking block 6 and the locking strip 7. After the locking block 6 and the locking strip 7 are separated, the user can remove the bottle cap 2, and then the user can efficiently replace the filter element 10 inside the bottle body 1.

[0029] Example 2

[0030] Please see Figure 1-7 Based on Embodiment 1, an annular groove 11 is provided on the top of the bottle body 1. An annular sealing ring 12 is snapped into the inner cavity of the annular groove 11. The top of the annular sealing ring 12 is fixedly connected to the inner wall of the bottle cap 2. Five limiting blocks 13 are fixedly connected to the bottom of the bottle cap 2. The side of the limiting block 13 near the filter element 10 is snapped into the filter element 10. Five reinforcing blocks 14 are fixedly connected to the front and rear sides of the inlet and outlet water pipes 3. The bottom of the reinforcing blocks 14 is fixedly connected to the bottle cap 2. A positioning ring 15 is fixedly connected to the bottom of the inner cavity of the bottle body 1. The surface of the positioning ring 15 is snapped into the inner cavity of the filter element 10. Annular reinforcing ribs 17 and vertical reinforcing ribs 16 are fixedly connected to the surface of the bottle body 1.

[0031] Specifically: the combination of the annular groove 11 and the annular sealing ring 12 improves the sealing performance of the bottle body 1 and the bottle cap 2; the limiting block 13 limits the position of the filter element 10; the reinforcing block 14 fixes the inlet and outlet water pipes 3; the positioning ring 15 limits the position of the filter element 10; and the combination of the annular reinforcing rib 17 and the vertical reinforcing rib 16 increases the strength of the bottle body 1.

[0032] The working principle of this utility model is as follows: Water enters through the right side of the inlet / outlet pipe 3, and enters the inner cavity of the bottle body 1 through the through hole 8. The filter element 10 filters the impurities in the water using the principle of water pressure. The filtered water will then enter the inner cavity of the inlet / outlet pipe 3 again through the connecting pipe 9, and then be discharged through the left side of the inlet / outlet pipe 3. When the user needs to replace the filter element 10, the user presses down the pressure relief valve 5 to reduce the pressure inside the bottle body 1. Then the user can rotate the bottle cap 2 to separate the locking block 6 and the locking strip 7. After the locking block 6 and the locking strip 7 are separated, the user can remove the bottle cap 2. At this time, the user can efficiently replace the filter element 10 inside the bottle body 1.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through the control unit. The control circuit of the control unit can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Therefore, the control method and circuit connection will not be explained in detail in this invention.
