Description

A marine water purification device that is easy to assemble and disassemble Technical Field

[0001] This utility model relates to the field of water purification equipment disassembly and assembly technology, specifically, to a marine water purification equipment that is easy to disassemble and assemble. Background Technology

[0002] Marine water purification equipment filters river water to make it drinkable. Currently, river water filtration typically uses a combination of three types of five filter cartridges, which are then passed through sequentially to purify the water. The five filter cartridges are installed in the following order: PP cotton, activated carbon, PP cotton, RO membrane, and activated carbon, as shown in Figure 1. Currently, when installing the filter cartridges, each of the five cartridges needs to be placed in a filter cylinder. During installation, to connect the inlet at the bottom of the filter cartridge to the outlet of the device, the cartridges need to be pressed down to ensure a proper connection. Furthermore, when replacing or installing new cartridges, the corresponding sealing caps must be opened sequentially before placing and resealing the cartridges, making the process cumbersome. Subsequent replacements also require opening the sealing caps and replacing the cartridges, resulting in repetitive and time-consuming operations. Summary of the Invention

[0003] The purpose of this invention is to provide a marine water purification device that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a marine water purification device that is easy to assemble and disassemble, including a water purifier shell. An installation groove is formed on the upper side of the water purifier shell near one side. A plate mounting groove is formed on the installation groove. Several filter chambers are arranged on the lower side of the plate mounting groove. Filter cartridges are installed inside each filter chamber. The filter chambers are arranged in a row. A sealing plate is arranged inside the plate mounting groove. Several fixing mechanisms are arranged on the upper side of the sealing plate. The fixing mechanisms fix the sealing plate inside the plate mounting groove. Several pressing mechanisms are fixed on the lower side of the sealing plate. The number and position of the pressing mechanisms correspond to the number of filter chambers. When the sealing plate is installed inside the plate mounting groove, the pressing mechanisms press the filter cartridges downwards.

[0005] As a further improvement to this technical solution, the shapes of the sealing plate and the plate mounting groove are adapted to each other, and a rubber sealing gasket is installed at the bottom of the plate mounting groove. When the sealing plate is fixed inside the plate mounting groove by the fixing mechanism, the rubber sealing gasket is pressed to block the gap between the sealing plate and the plate mounting groove.

[0006] As a further improvement to this technical solution, the sidewalls between the plurality of filter chambers are all configured to protrude into the filter chamber, and the fixing mechanism includes a long screw, one end of which passes through the sealing plate and is threadedly connected to the sidewall between the plurality of filter chambers.

[0007] As a further improvement to this technical solution, a metal disc is slidably sleeved on the long screw, and several arc-shaped spring steel sheets are fixed in a ring array on the arc-shaped sidewall of the metal disc. The arc-shaped spring steel sheets are arc-shaped, and one end of them extends downward and contacts the sidewall of the sealing plate.

[0008] As a further improvement to this technical solution, several limiting rings are fixed on the upper side wall of the sealing plate with the axis of several long screws as the center. One end of the arc-shaped spring steel sheet contacts the limiting ring. When the long screws are threadedly connected to the side wall between the filter chambers, the long screws press down on the metal disc. The pressed metal disc drives the arc-shaped spring steel sheet to undergo elastic deformation, causing the arc-shaped spring steel sheet to press down on the sealing plate.

[0009] As a further improvement to this technical solution, the pressing mechanism includes several plug-in plates fixed on the lower side of the sealing plate. The shape of the plug-in plates and the filter chambers are the same. When the sealing plate is installed inside the plate mounting groove, the side wall of the plug-in plate contacts the side wall of the filter chamber.

[0010] As a further improvement to this technical solution, a placement groove is provided at the bottom of the plug-in plate, and a plastic spring is fixed in the placement groove. A plastic push plate is fixed at the other end of the plastic spring. Several limiting rods are fixed in a circular array at the center of the placement groove at the bottom of the plug-in plate. The circle formed by the several limiting rods is adapted to the shape of the filter element. When the sealing plate is installed in the plate mounting groove, the plastic spring presses down on the plastic push plate, causing the plastic push plate to push the filter element down.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This easy-to-assemble marine water purification equipment combines several filter chambers and uses a fixing mechanism to fix the sealing plate in the plate mounting groove, allowing the sealing plate to directly seal all the filter chambers. This eliminates the hassle of repeatedly opening the sealing cover, as was previously required by the operator. Furthermore, during the installation of the sealing plate, a pressing mechanism presses the filter element, eliminating the need for the operator to press each filter element individually and reducing the hassle of replacing the filter elements.

[0026] Example 1

[0027] To address the inconvenience of disassembling and reassembling each sealing cap when replacing filter element 4 in the water purification device shown in Figure 1, this solution improves upon the following: This embodiment provides a marine water purification device that is easy to disassemble and assemble. Referring to Figures 2-9, it includes a water purifier housing 1. An installation groove is provided on the upper side of the housing 1 near one side. Indicator lights and control buttons are located on the front of the housing 1. The installation groove is located on the back of the housing 1, and a plate mounting groove 5 is provided on the mounting groove. Several filter chambers 3 are located below the plate mounting groove 5, and these filter chambers 3 are connected sequentially by rubber tubes. The first filter chamber 3, which comes into contact with the river water, is connected to a rubber tube at its bottom. Then, the bottom of filter chamber 3 is connected to the bottom of another filter chamber 3 via a rubber tube, and so on, until all filter chambers 3 are connected together. This connection method is a commonly used technology in water purification equipment, and this solution will not elaborate on it. Inside the filter chamber 3, a filter element 4 is installed. The inlet of the filter element 4 is connected to a rubber tube at the bottom of the filter chamber 3. Water first enters the filter element 4 through the rubber tube, and then the filter element 4 filters the water before it enters the interior of the filter chamber 3. Several filter chambers 3 are arranged in a row.

[0028] A sealing plate 2 is provided inside the plate mounting groove 5. The shape of the sealing plate 2 is adapted to the plate mounting groove 5. Several fixing mechanisms are provided on the upper side of the sealing plate 2. The fixing mechanisms fix the sealing plate 2 inside the plate mounting groove 5. A rubber sealing gasket 51 is installed at the bottom of the plate mounting groove 5. When the sealing plate 2 is fixed inside the plate mounting groove 5 by the fixing mechanisms, the rubber sealing gasket 51 is compressed and blocks the gap between the sealing plate 2 and the plate mounting groove 5, thereby improving the sealing effect between the sealing plate 2 and the plate mounting groove 5.

[0029] The sealing plate 2 is fixed in the plate mounting groove 5 by the fixing mechanism, so that the sealing plate 2 directly seals all the filter chambers 3, eliminating the trouble of the operator repeatedly opening the sealing cover. At the same time, during the installation of the sealing plate 2, the filter element 4 is pressed by the pressing mechanism, eliminating the trouble of the operator pressing each filter element 4, reducing the trouble of the operator replacing the filter element 4.

[0030] Because the multiple filter chambers 3 are arranged in a row, and because the volume of the water purifier shell 1 is limited, the distance between the side walls of two filter chambers 3 is relatively small, resulting in poor stability of the side walls between the two filter chambers 3. In order to ensure the stability of the side walls between the two filter chambers 3, the side walls between the multiple filter chambers 3 are all designed to bulge inwards towards the inside of the filter chamber 3. The inward bulging shape between the two filter chambers 3 can improve the stability between the two filter chambers 3.

[0031] The operator places several filter elements 4 into the filter chamber 3, aligning the inlet of the filter element 4 with the rubber tube at the bottom of the filter chamber 3. To ensure the accuracy of the connection between the filter element 4 and the rubber tube at the bottom of the filter chamber 3, several guide rods 31 are fixed in a circular array at the bottom of the filter chamber 3. The guide rods 31 include a vertical section and an outwardly extending inclined section. The vertical section is inserted and fixed to the bottom of the filter chamber 3, and the inclined section is inserted and fixed to the side wall of the filter chamber 3. When the filter element 4 is inserted into the filter chamber 3, the inclined sections of the guide rods 31 guide the bottom of the filter element 4 toward the middle of the filter chamber 3, while the vertical sections restrict the position of the filter element 4, so that the inlet of the bottom of the filter element 4 can be accurately inserted into the rubber tube.

[0032] Previously, after the filter element 4 was placed, it was necessary to manually press it down. This device has several pressing mechanisms fixed on the lower side of the sealing plate 2. The number and position of the pressing mechanisms and the filter chambers 3 are all corresponding. When the sealing plate 2 is installed inside the plate mounting groove 5, the pressing mechanism presses the filter element 4 down. After the sealing plate 2 is fixed in the plate mounting groove 5, the pressing mechanism directly presses the filter element 4 down, eliminating the trouble of manual pressing.

[0033] The pressing mechanism includes several plug-in plates 21 fixed to the lower side of the sealing plate 2. These plug-in plates 21 and several filter chambers 3 have the same shape. When the sealing plate 2 is installed inside the plate mounting groove 5, the sidewalls of the plug-in plates 21 contact the sidewalls of the filter chambers 3. This contact improves the accuracy of the sealing plate 2's positioning in the plate mounting groove 5. A placement groove is provided at the bottom of the plug-in plates 21. The placement groove is cylindrical, and a plastic spring 22 is fixed in the placement groove. The plastic spring 22, made of plastic, can reduce water contamination. The plastic spring 22 can be made of PA or POM material. A plastic push plate 23 is fixed to the other end of the plastic spring 22. Several limiting rods 24 are fixed in a circular array at the bottom of the plate 21 with the center of the placement slot. The circle formed by the limiting rods 24 is adapted to the shape of the filter element 4. When the sealing plate 2 is installed in the plate mounting slot 5, one end of the filter element 4 is inserted between the limiting rods 24. As the sealing plate 2 moves closer to the plate mounting slot 5, the top of the filter element 4 comes into contact with the plastic push plate 23. Then the sealing plate 2 continues to move down, causing the plastic push plate 23 to squeeze the plastic spring 22. At this time, the plastic spring 22 is compressed, and the counter-force generated by the compression of the plastic spring 22 pushes the filter element 4 down. The plastic spring 22 presses down on the plastic push plate 23, causing the plastic push plate 23 to push the filter element 4 down, thus eliminating the trouble of manually pressing the filter element 4.

[0034] After the sealing plate 2 enters the plate mounting groove 5, it needs to be fixed in the plate mounting groove 5. When fixing, it is necessary to ensure the sealing effect between the edge of the sealing plate 2 and the plate mounting groove 5, and also to ensure that there is no leakage between the two filter chambers 3. This requires a lot of screws for fixing. However, using a number of screws is not only numerous, but also wastes a lot of time when the operator changes the screws. This solution improves the fixing mechanism, which includes a long screw 6. One end of the long screw 6 passes through the sealing plate 2 and is threaded to the side wall between a number of filter chambers 3. At the same time, a metal disk 61 is slidably sleeved on the long screw 6. A number of arc-shaped spring steel sheets 62 are fixed in a ring array on the arc-shaped side wall of the metal disk 61. The arc-shaped spring steel sheets 62 are arc-shaped and elastic, and one end of them extends downward to contact the side wall of the sealing plate 2.

[0035] When the long screw 6 is threaded into the side wall between the filter chambers 3, the long screw 6 presses down on the metal disc 61. When the metal disc 61 moves downward, it presses down on the arc-shaped spring steel sheet 62. The pressed metal disc 61 causes the arc-shaped spring steel sheet 62 to undergo elastic deformation. The deformed arc-shaped spring steel sheet 62 pushes the sealing plate 2 in the opposite direction, causing the arc-shaped spring steel sheet 62 to press down on the sealing plate 2. The sealing plate 2 is fixed in the plate mounting groove 5 by means of the elastic force generated by the deformation of the arc-shaped spring steel sheet 62. The position where the arc-shaped spring steel sheet 62 presses down on the sealing plate 2 is close to the edge of the sealing plate 2, which improves the sealing effect between the edge of the sealing plate 2 and the plate mounting groove 5.

[0036] Meanwhile, a sleeve 63 is fitted on the lower side of the metal disc 61 where the long screw 6 is located. When the long screw 6 is tightened, the top of the arc-shaped spring steel sheet 62 and the sleeve 63 come into contact, so that the sleeve 63 presses against the sealing plate 2, further improving the stability of the sealing plate 2 being fixed on the plate mounting groove 5.

[0037] To prevent one end of the arc-shaped spring steel sheet 62 from detaching from the sealing plate 2 and thus failing to press against the sealing plate 2, several limiting rings 25 are fixed on the upper side wall of the sealing plate 2, centered on the axis of several long screws 6. One end of the arc-shaped spring steel sheet 62 contacts the limiting ring 25, and the limiting ring 25 prevents the arc-shaped spring steel sheet 62 from extending further outward, thus ensuring the effect of the arc-shaped spring steel sheet 62 pressing against the sealing plate 2.

[0038] When the operator disassembles the sealing plate 2, the long screw 6 can be removed from the plate mounting groove 5 by hand or wrench. Then the sealing plate 2 is taken out of the plate mounting groove 5. After the operator replaces the filter element 4, the sealing plate 2 is installed in the plate mounting groove 5. Then the arc-shaped spring steel sheet 62 is positioned and the long screw 6 is tightened to complete the replacement of the filter element 4. The operation is convenient and the replacement speed is fast.

[0039] At the same time, a protective shell can be installed on the mounting slot. The protective shell protects several fixing mechanisms and prevents external impurities from reaching the fixing mechanisms.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
