Description

Technical Field

[0001] This utility model relates to the field of water softener technology, specifically to a water softener with a modular, easy-to-maintain filter cartridge. Background Technology

[0002] A water softener is a household or commercial device that uses specific technology and equipment to remove or reduce hardness components such as calcium and magnesium ions in water, thereby improving water hardness.

[0003] In the existing technology, water softeners mainly consist of a resin tank, a controller, a conduit, and a control valve. The resin tank is filled with resin in the shape of small balls to form a filter element. The controller is installed at the top of the resin tank. Hard water enters the resin tube through the conduit. The resin absorbs the calcium and magnesium ions in the hard water. When the hard water flows to the bottom of the resin tank, it is refluxed. The control valve is used to block the conduit.

[0004] However, after the resin absorbs calcium and magnesium ions for a period of time, the efficiency of the resin in absorbing calcium and magnesium ions decreases. Users need to remove the controller from the top of the resin tank and then pour the resin out from the top of the resin tank to replace the filter cartridge. This operation is time-consuming and laborious, affecting the performance of the water softener. Utility Model Content

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-6 As shown, a modular, easy-to-maintain water softener includes: a resin tank 1, a base 6, and a return pipe 12.

[0033] A controller 3 is fixedly connected to the top of the resin tank 1. A water outlet pipe 4 is fixedly connected to the side of the controller 3. A water inlet pipe 2 is located on the side of the controller 3 away from the water outlet pipe 4. The bottom end of the water inlet pipe 2 is fixedly connected to the resin tank 1 and communicates with the interior of the resin tank 1. A base 6 is located at the bottom of the resin tank 1 and abuts against the bottom of the resin tank 1. A carrier tank 11 is fixedly connected to the top of the base 6 and fits against the inner wall of the resin tank 1. A return pipe 12 is located inside the carrier tank 11, and its top end is fixedly connected to the resin tank 1 and communicates with the controller 3. Resin is placed inside the carrier tank 11. The resin tank 11 is formed by the accumulation of resin. When hard water enters the tank 11 through the inlet pipe 2, the resin removes calcium and magnesium ions from the hard water. The hard water is softened when it reaches the bottom of the tank 11. The softened water enters the return pipe 12 and flows upward, then enters the controller 3 and is discharged from the outlet pipe 4. When the filter element needs to be replaced, the user controls the resin tank 1 to move upward first, removing the resin tank 1 from the tank 11. The inner wall of the resin tank 1 slides vertically upward along the tank 11, and the resin tank 1, along with the controller 3, is removed directly from the top of the tank 11, avoiding the operation of removing the controller 3 from the top of the resin tank 1 and saving working time.

[0034] Users can directly replace the resin stored in the carrier tank 11, avoiding the time-consuming and laborious process of removing the resin from the top of the controller 3. The base 6 achieves the effect of sealing the bottom of the carrier tank 11, and at the same time, the base 6 achieves the effect of vertical support.

[0035] In some specific implementations, handles 5 are fixedly connected to both sides of the outer wall of the resin tank 1. When the resin tank 1 is removed from the carrier tank 11, the user can pull the resin tank 1 by controlling the handles 5 with both hands.

[0036] In some specific embodiments, the carrier tank 11 is slidably connected to the inner wall of the resin tank 1, and a limiting groove 10 is formed on the top of the resin tank 1. The inner wall of the limiting groove 10 is abutting and connected to the top of the carrier tank 11. When the resin tank 1 is fitted onto the carrier tank 11, the carrier tank 11 is inserted into the inner wall of the limiting groove 10, and the abutting between the inner wall of the limiting groove 10 and the carrier tank 11 provides a limiting function for the top of the carrier tank 11.

[0037] In some specific embodiments, the base 6 has a sealing groove 15 around the axis, a locking assembly is fixedly connected to the top of the base 6, and a sealing ring 18 is fixedly connected to the bottom of the resin tank 1. The sealing ring 18 is slidably connected to the inner wall of the sealing groove 15. When the resin tank 1 is installed on the base 6, the sealing ring 18 fixed at the bottom of the resin tank 1 slides along the inner wall of the sealing groove 15, and the locking assembly locks and fixes both ends of the resin tank 1 to prevent the resin tank 1 from shaking.

[0038] In some specific embodiments, a sealing gasket 16 is fixedly connected to the inner wall of the sealing groove 15. The sealing gasket 16 is plastic and abuts against the bottom end of the sealing ring 18. A plurality of connecting seats 17 are fixedly connected at equal intervals along the axis of the bottom end of the sealing ring 18. The connecting seats 17 abut against the sealing gasket 16. The cross-section of the connecting seats 17 is triangular. When the bearing tank 11 is filled with a large amount of hard water, the hard water will flow out from the gap between the limiting groove 10 and the bearing tank 11. The hard water flows downward along the outer wall of the bearing tank 11. When the hard water flows between the resin tank 1 and the base 6, the sealing ring 18... By abutting against the sealing gasket 16, the gap between the resin tank 1 and the base 6 is sealed, thereby achieving the effect of blocking hard water. When the sealing ring 18 and the sealing gasket 16 abut against each other, the connecting seat 17 fixed to the sealing ring 18 further abuts against the sealing gasket 16. The shape of the connecting seat 17 can better compress the sealing gasket 16. On the one hand, the sealing gasket 16 is squeezed and deformed to fill the sealing groove 15, thus better sealing against hard water. On the other hand, the shape of the connecting seat 17 can fully abut against the sealing gasket 16, thereby limiting the sealing ring 18 and ensuring the stability of the bottom of the resin tank 1.

[0039] In some specific embodiments, the locking assembly is provided in two sets and located on both sides of the resin tank 1 respectively. The locking assembly includes a locking plate 8 and a locking seat 9. Positioning plates 7 are fixedly connected to both ends of the resin tank 1. Positioning grooves 14 are respectively opened on both sides of the top of the base 6. The inner wall of the positioning groove 14 abuts against the positioning plate 7. The locking plate 8 is rotatably connected to the side end of the locking seat 9. The locking plate 8 abuts against the top and side ends of the positioning plate 7 respectively. When the resin tank 1 is installed on the base 6, the positioning plates 7 fixed at both ends of the resin tank 1 are embedded in the positioning grooves 14. The inner wall of the positioning groove 14 abuts against the positioning plate 7. The user rotates the locking plate 8 to abut against the top and side ends of the positioning plate 7, thereby achieving the effect of fixing the resin tank 1.

[0040] In some specific implementations, a filter plug 13 is fixedly connected to the bottom end of the return pipe 12, and a sensor 19 is fixedly connected to the inner wall of the return pipe 12. The filter plug 13 is spherical. When hard water softens and enters the return pipe 12, the filter plug 13 can filter the softened water. The shape of the filter plug 13 increases the effective area for water to enter the return pipe 12. When the resin fails, the sensor 19 detects that the calcium and magnesium ions in the water returning to the return pipe 12 exceed the standard. The sensor 19 transmits the signal to the controller 3, and the controller 3 alarms to remind the user.

[0041] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
