Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water treatment filtering device. Background Art

[0002] Due to the poor water quality of domestic water in some areas, the water coming out of the water pipe is rusty yellow and even has large particles of impurities. Therefore, more and more families choose to install filters to purify domestic water.

[0003] At present, water filters have entered thousands of households. However, due to the different specifications of the water pipes installed in home decoration, there are differences in the pipe orifice diameters of the filters. Single-orifice filters require various pipe connection structures to adapt to the installation and connection of domestic water pipes in different families. Since the connection between the connecting pipe and the filter is relatively troublesome and the sealing performance at the connection is poor, especially during the process of gradually increasing the water pressure at the pipe orifice, small differences in the orifice diameters are likely to cause leakage problems. When the installation is not firm, as the water pressure increases, the water flow is very easy to leak out from the connection. Therefore, the connection ports of the filters need to be redesigned to adapt to water pipes with different orifice diameters in different families. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water treatment filtering device, which can be clamped at the pipe orifice under the action of water flow when the filter is connected to the domestic water pipe. As the water pressure increases, the pressure on the pipe orifice becomes larger, making the connection more tight and avoiding the leakage of water flow at the pipe orifice.

[0005] The utility model adopts the following technical scheme: the water treatment filtering device includes a filter body, a cavity is arranged inside the filter body, and a filter element is installed at the front end of the cavity. It is characterized in that: a tightening connecting pipe is arranged at the tail end of the filter body, the tail end of the filter body is connected to an external water pipe through the tightening connecting pipe, a first pressing block is installed inside the port of the tightening connecting pipe, a second pressing block is installed outside the port of the tightening connecting pipe, the first pressing block and the second pressing block are circumferentially distributed in the tightening connecting pipe, a limiting ring is arranged at the port of the tightening connecting pipe far away from the filter body, a motion component is arranged at the port of the tightening connecting pipe, the motion component includes a closing plate installed at the port of the tightening connecting pipe, the closing plate is connected to the first pressing block through the motion component, the closing plate drives the second pressing block to move through a connecting component, the connecting component includes a connecting rod installed inside the tightening connecting pipe, two ends of the connecting rod are respectively connected to the closing plate and the second pressing block, the closing plate moves along the axial direction of the tightening connecting pipe under the action of the water flow of the external water pipe, drives the first pressing block to abut against the tightening connecting pipe through the motion component, and at the same time drives the second pressing block to abut against the port of the tightening connecting pipe through the connecting component, so as to ensure the sealing performance of the interface between the filter body and the external water pipe.

[0006] A further solution of the present utility model is that the moving assembly further includes a rotating disk installed in the screwing connection pipe. An arc-shaped groove is formed on the rotating disk. An extending arm is provided on the inner arc side of the first pressing block. A convex shaft is provided at the upper part of the end of the extending arm close to the rotating disk. The convex shaft slides in the arc-shaped groove. A groove rod is installed on the upper end surface of the rotating disk. A groove-shaped hole is formed on the closing plate. The groove rod passes through the groove-shaped hole and is adapted to the groove-shaped hole. When the closing plate moves downward, the groove-shaped hole acts on the groove rod to make the groove rod rotate, and at the same time drives the rotating disk to rotate. The rotation of the rotating disk drives the first pressing block to contact the inner wall of the screwing connection pipe.

[0007] A further solution of the present utility model is that the notch of the arc-shaped groove approaches the center from the outside of the rotating disk, and the first pressing block is a circular arc-shaped clamping block.

[0008] A further solution of the present utility model is that a sliding square block is provided at the lower end of the first pressing block. A sliding arm is provided at the edge of the filter body located in the screwing connection pipe. A first sliding groove is formed on the sliding arm. The sliding square block is adapted to the first sliding groove and slides in the first sliding groove. The first pressing block slides in the first sliding groove through the cooperation of the sliding square block and the first sliding groove, so as to prevent the first pressing block from rotating under the action of the rotating disk.

[0009] A further solution of the present utility model is that the connection assembly further includes a plug block installed at the end of the screwing connection pipe. The plug block is located between every two second pressing blocks. A second sliding groove is provided on the outside of the limit ring at the end of the screwing connection pipe. A second sliding block is provided at the lower end of the second pressing block. The second sliding block is adapted to the second sliding groove. The plug block is connected to the closing plate through a second connecting rod. When the closing plate moves downward, it drives the plug block to move downward. Under the action of the inclined surface, the plug block drives the second pressing block to slide outward along the direction of the second sliding groove.

[0010] A further solution of the present utility model is that the part of the second pressing block in contact with the plug block is an inclined surface, and the second sliding groove is along the radial direction of the limit ring.

At the same time, the closing plate drives the first pressing block to move through the movement component, and the first pressing block moves outward along the radial direction of the screwing connection pipe, thereby driving the first pressing block to tightly press the connection place between the inside of the screwing connection pipe and the port of the external water pipe, further avoiding water overflow, improving the tightness of the connection between the filter and the water pipe. At the same time, after the water pipe switch is tightened and the water is cut off, the closing plate automatically moves upward to close the port position of the screwing connection pipe, improving the sensitivity of the water flow opening and closing of the water pipe.

Detailed implementation manners

[0025] The following provides a detailed description of the present utility model in conjunction with the accompanying drawings and embodiments:

[0026] Refer to the attached Figures 1-9 , a water treatment filtration device according to the present utility model includes: a filter body 1, a cavity is provided inside the filter body 1, a filter element 12 is installed at the front end of the cavity, a tightening connection pipe 11 is provided at the tail end of the filter body 1, the tail end of the filter body 1 is connected to an external water pipe 2 through the tightening connection pipe 11, the tightening connection pipe 11 is made of flexible telescopic plastic material, a first pressing block 31 is installed inside the port of the tightening connection pipe 11, a second pressing block 32 is installed outside the port of the tightening connection pipe 11, the first pressing block 31 and the second pressing block 32 are circumferentially distributed in the tightening connection pipe 11, a limiting ring 111 is provided at the port of the tightening connection pipe 11 away from the filter body 1, a motion assembly is provided at the port of the tightening connection pipe 11, the motion assembly includes a closing plate 33 installed at the port of the tightening connection pipe 11, the closing plate 33 is connected to the first pressing block 31 through the motion assembly, the closing plate 33 drives the second pressing block 32 to move through a connection assembly, the connection assembly includes a connecting rod 41 installed inside the tightening connection pipe 11, and both ends of the connecting rod 41 are respectively connected to the closing plate 33 and the second pressing block 32;

[0027] Unscrew the screw port at the port of the external water pipe 2, align the tightening connection pipe 11 with the external water pipe 2 and then rotate it to initially connect the device to the external water pipe 2. When using the device to filter domestic water, turn on the switch of the external water source. Under the action of the water flow pressure, the water flow pushes the closing plate 33 downward and enters the filter body 1. The domestic water is effectively filtered by the filter element 12 inside the filter body 1. The closing plate 33 drives the connecting rod 41 to move downward, driving the second pressing block 32 to move around, thereby expanding the diameter of the port of the tightening connection pipe 11, so as to further fit with the external water pipe 2, avoiding water leakage from the part of the interface with the external water pipe 2 under the action of water pressure. At the same time, the closing plate 33 drives the first pressing block 31 to move through the motion assembly, and the first pressing block 31 moves outward along the radial direction of the tightening connection pipe 11, thereby driving the first pressing block 31 to tightly press the connection between the inside of the tightening connection pipe 11 and the port of the external water pipe 2, further avoiding water overflow, improving the tightness of the connection between the filter and the water pipe. At the same time, after the water pipe switch is tightened and the water stops flowing, the closing plate 33 automatically moves upward to close the port position of the tightening connection pipe 11, improving the sensitivity of the water flow opening and closing of the water pipe.

[0028] The moving component further includes a rotating disk 42 installed in the screwing connection pipe 11. An arc-shaped groove 421 is formed in the rotating disk 42. The notch of the arc-shaped groove 421 approaches the center from the outside of the rotating disk 42. The first pressing block 31 is an arc-shaped clamping block. An extending arm 311 is arranged on the inner arc side of the first pressing block 31. A convex shaft 312 is arranged on the upper part of the end of the extending arm 311 close to the rotating disk 42. The convex shaft 312 slides in the arc-shaped groove 421. A groove rod 422 is installed on the upper end surface of the rotating disk 42. A groove-shaped hole 331 is formed in the closing plate 33. The groove rod 422 passes through the groove-shaped hole 331 and is adapted to the groove-shaped hole 331. A sliding square block 313 is arranged at the lower end of the first pressing block 31. A sliding arm 13 is arranged at the edge of the filter body 1 on the screwing connection pipe 11. A first sliding groove 131 is formed in the sliding arm 13. The sliding square block 313 is adapted to the first sliding groove 131 and slides in the first sliding groove 131. After the switch of the external water pipe 2 is opened, the water flow pushes the closing plate 33 downward under the action of water pressure. The closing plate 33 moves downward and drives the groove rod 422 to rotate through the groove-shaped hole 331. The groove rod 422 drives the rotating disk 42 to rotate. The rotating disk 42 abuts against the convex shaft 312 through the arc-shaped groove 421, so as to drive the extending arm 311 to slide along the direction of the first sliding groove 131. The extending arm 311 drives the first pressing block 31 to tightly press the inner wall of the screwing connection pipe 11 against the port of the external water pipe 2, thereby improving the sealing performance of the port.

[0029] The connecting component further includes a plug block 43 installed at the end of the screwing connecting pipe 11. The plug block 43 is located between every two second abutting blocks 32. The part of the second abutting block 32 in contact with the plug block 43 is an inclined surface. A second sliding groove 112 is provided on the outside of the limiting ring 111 at the end of the screwing connecting pipe 11. The second sliding groove 112 is along the radial direction of the limiting ring 111. A second sliding block 321 is provided at the lower end of the second abutting block 32. The second sliding block 321 is adapted to the second sliding groove 112. The plug block 43 is connected to the closing plate 33 through a second connecting rod 44. When the closing plate 33 moves downward, it drives the plug block 43 to move downward. Under the action of the inclined surface, the plug block 43 drives the second abutting block 32 to slide outward along the direction of the second sliding groove 112, so as to tightly abut and fit the screwing connecting pipe 11 with the external water pipe 2, avoiding water flow from overflowing outward at the connection between the screwing connecting pipe 11 and the external water pipe 2 under the action of water pressure and affecting the sealing performance of the device. It should be noted that as the opening and closing of the external water pipe switch 2 increases and the water flow pressure increases, the downward movement distance of the closing plate 33 increases. In this case, the radial outward movement distance of the first abutting block 31 under the action of the extending arm 311 becomes larger, so as to further tighten the inner wall of the screwing connecting pipe 11 and the port of the external water pipe 2. At the same time, the downward movement distance of the plug block 43 increases, driving the second abutting block 32 to move outward along the direction of the second sliding groove 112 by a larger distance, further tightening the connection between the screwing connecting pipe 11 and the external water pipe 2. Under the dual action of the first abutting block 31 and the second abutting block 32, the sealing performance between the screwing connecting pipe 11 and the external water pipe 2 is further improved, facilitating the use of users.

[0030] A second connecting arm 14 is provided on the inner side of the limiting ring 111. An elastic member 15 is installed on the second connecting arm 14. The other end of the elastic member 15 is connected to the inner side of the closing plate 33. In the initial state, the closing plate 33 is tightly abutted and sealed with the inner side of the limiting ring 111 under the action of the elastic member 15, so as to prevent the closing plate 33 from falling into the filter body 1 under the action of gravity and affecting the use. Under the action of water flow, the closing plate 33 moves downward, offsetting the action of the elastic member 15. The downward movement of the closing plate 33 drives the first abutting block 31 and the second abutting block 32 to respectively tighten the screwing connecting pipe 11. After the external water pipe 2 is closed, under the action of the elastic member 15, the closing plate 33 moves toward the limiting ring 111 and fits and contacts the limiting ring 111, avoiding the water flow overflow at the connection between the external water pipe 2 and the screwing connecting pipe 11.
