DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Please refer to Figures 1-6 The present application provides a technical solution: a reverse osmosis equipment with filter core convenient to replace quickly, comprising a filter box 1, the top of the filter box 1 is provided with a box cover 2, the inside of the filter box 1 is provided with a filter core 5, one side of the bottom of the filter box 1 is provided with a water outlet pipe 4, the inside bottom side of the filter box 1 and the inside bottom side of the box cover 2 are both provided with a sealing assembly 6, the top of the box cover 2 is provided with a water inlet pipe 3, and the inside bottom side of the box cover 2 is provided with a fixing assembly 7.

[0031] The sealing assembly 6 comprises a plurality of piston boxes 601 arranged in an equiangular circular array, the piston boxes 601 are fixedly connected in the inside of the filter box 1, the piston plate 603 is slidably connected in the inside of the piston box 601, the clamping block 602 and the first air bag 605 are fixedly connected to one side of the piston plate 603 close to the filter core 5, the other end of the clamping block 602 extends to the outside of the piston box 601 and is provided with a clamping groove, the other side of the first air bag 605 is fixedly connected with the inner wall of the piston box 601, the other side of the piston plate 603 is fixedly connected with the first spring 604, the other end of the first spring 604 is fixedly connected with the inner wall of the piston box 601, the second air bag 607 is arranged above the piston box 601, the air guide pipe 606 is communicated with the top of the first air bag 605, the other end of the air guide pipe 606 extends to the outside of the piston box 601 and is communicated with the second air bag 607, and the sealing block 608 is fixedly connected to one side of the second air bag 607 close to the filter core 5.

[0032] In use, the external water supply system guides water into the internal space of the filter core 5 through the water inlet pipe 3, and the filtered water flows out of the water outlet pipe 4 after being filtered by the filter core 5. If the filter core 5 needs to be installed or replaced, the operator aligns and inserts the filter core 5 into the annular groove. In this process, the filter core 5 extrudes the clamping block 602, thereby causing the clamping block 602 to slide along the inner wall of the piston box 601 together with the piston plate 603 and compressing the first spring 604. Once the bottom of the filter core 5 is completely embedded in the annular groove, the first spring 604 pushes the piston plate 603 and the clamping block 602 to slide reversely by using its elastic force, until the clamping block 602 is clamped into the clamping groove on the filter core 5. At the same time, the movement of the piston plate 603 compresses the first air bag 605, forcing the gas in the first air bag 605 to be transmitted to the second air bag 607 through the gas guide pipe 606. As the second air bag 607 expands, it will drive the sealing block 608 to tightly fit the connection part of the filter core 5 and the filter box 1, effectively preventing water from seeping into the annular groove and avoiding the possible corrosion problem of the components.

[0033] The fixing assembly 7 includes four sleeves 701, which are distributed in a cross symmetric manner on the inner bottom side of the box cover 2. The first rotating shaft 702 is slidably connected inside the sleeve 701. The sleeve 701 is provided with a through hole 705 with a J-shaped cross section. The sliding block 703 is slidably connected inside the through hole 705. One side of the sliding block 703 is fixedly connected with the outer circumferential side of the first rotating shaft 702. The first rotating shaft 702 extends to the outside of the box cover 2 and is fixedly connected with the hand crank 706 at one end. The first rotating shaft 702 is fixedly connected with the second rotating shaft 707 at the other end. The second rotating shaft 707 extends to the outside of the sleeve 701 and is provided with a second sliding groove. The second rotating shaft 707 is slidably connected inside the sleeve 701. The inner bottom side of the filter box 1 and the inner bottom of the box cover 2 are both provided with an annular groove. The filter core 5 slides in the annular groove. The inner bottom side of the box cover 2 is provided with a first sliding groove. The top of the filter box 1 is provided with an annular protrusion, which is slidably connected in the first sliding groove. The second sliding groove is provided on the side of the annular protrusion away from the filter core 5. The second spring 704 is sleeved on the outer circumferential side of the second rotating shaft 707. The other end of the second spring 704 is fixedly connected with the inner bottom side of the sleeve 701. One end of the clamping block 602 is clamped with the clamping groove. The clamping grooves are symmetrically distributed on the upper and lower sides of the filter core 5. The filter core 5 is located on the same axis as the filter box 1. The water inlet pipe 3 is connected with the inside of the filter core 5. The sealing block 608 is provided as an elastic member.

[0034] The embodiment is specific: after the bottom of the filter element 5 is fixed, the staff then moves the box cover 2 to the filter box 1, aligns the first sliding groove with the filter box 1 and the annular groove with the filter element 5 respectively, and lightly presses the top end of the box cover 2 to make the filter box 1 slide into the annular sliding groove, and the filter element 5 also accurately falls into the annular groove at the same time. At this time, the clamping block 602 immediately clamps the filter element 5, and then the staff presses and rotates the hand crank 706. The hand crank 706 drives the second rotating shaft 707 and the sliding block 703 to slide in the sleeve 701 and the through hole 705 respectively through the first rotating shaft 702. In this process, the second spring 704 is compressed by the first rotating shaft 702. After rotation is completed, the staff releases the hand crank 706, and the second spring 704 immediately rebounds to push the related components to slide. The sliding block 703 is stably clamped in the through hole 705, and one end of the second rotating shaft 707 falls into the second sliding groove to fix the annular protrusion and the first sliding groove, thereby ensuring the stability of the connection between the box cover 2 and the filter box 1.

[0035] Working principle: when in use, the external water supply device injects water into the inside of the filter element 5 through the water inlet pipe 3. The water flows out of the water outlet pipe 4 after being filtered by the filter element 5. When it is necessary to install and replace the filter element 5, the staff inserts the filter element 5 into the annular groove. The filter element 5 extrudes the clamping block 602, which drives the piston plate 603 to slide along the inner wall of the piston box 601 to compress the first spring 604. When the bottom of the filter element 5 is completely inserted into the annular groove, the first spring 604 rebounds to drive the piston plate 603 and the clamping block 602 to slide, so that the clamping block 602 is inserted into the clamping groove to fix the filter element 5. At the same time, the piston plate 603 extrudes the first air bag 605 to input gas into the second air bag 607 through the gas guide pipe 606, and the second air bag 607 drives the sealing block 608 to seal the connection between the filter element 5 and the filter box 1.

[0036] When the fixing of the bottom of the filter element 5 is completed, the staff then operates the box cover 2 to move it to the filter box 1. When the first sliding groove and the annular groove are respectively aligned with the filter box 1 and the filter element 5, the top of the box cover 2 is pressed to make the filter box 1 enter the sliding groove and the filter element 5 enter the annular groove. The clamping block 602 clamps and fixes the filter element 5 to prevent the filter element 5 from shaking during work. At this time, the staff presses and rotates the hand crank 706. The hand crank 706 drives the second rotating shaft 707 and the sliding block 703 to slide in the sleeve 701 and the through hole 705 respectively through the first rotating shaft 702. The first rotating shaft 702 compresses the second spring 704. When rotation is completed, the staff stops pressing, and the second spring 704 rebounds to drive the first rotating shaft 702 to slide, so that the sliding block 703 is clamped in the through hole 705 and one end of the second rotating shaft 707 stays in the second sliding groove to fix the annular protrusion and the first sliding groove.

[0037] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
