[0002] As a vital component of the building water supply and drainage system, the building water supply and drainage purification and filtration device can effectively remove suspended impurities in the water, improve water quality, and ensure the safety and sanitation of water used inside the building. According to the different filtering materials, the building water supply and drainage purification and filtration devices can be divided into two categories: granular material filtration and porous material filtration. Common granular material filtration devices include sand filters, activated carbon filters, etc., while porous material filtration devices include ceramic filters, membrane filters, etc.

[0003] Most of the existing building water supply and drainage purification and filtering devices connect the two sections of pipes that need to be matched through the water inlet interface and the water outlet interface, and then treat the sewage entering from the water inlet interface through the internal filtering and purification mechanism, and then discharge the treated sewage through the pipe connected to the water outlet interface;

[0004] As the use time and filtering work continue, operators need to regularly inspect, maintain, and even replace and repair the purification and filtering devices at designated locations. Existing purification and filtering devices mostly use flanges to connect the interfaces to the pipelines. Therefore, when users replace them, they need to wear corresponding disassembly tools to disassemble the installed bolts. During the bolt disassembly process, the bolts are prone to rust due to the influence of use time and outdoor environment, making it difficult for operators to quickly remove the bolts during disassembly, resulting in a long time spent on the entire disassembly and installation process. Summary of the invention

[0005] The object of the present invention is to provide a building water supply and drainage purification filtering device and method that is easy to replace and install, and can enable users to easily and quickly complete the disassembly and assembly of the corresponding water supply and drainage purification filtering device through the provided components.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0030] See also Figures 1 to 9The present invention provides a building water supply and drainage purification and filtering device and method that are easy to replace and install: comprising a purification box body 1, a rotating pipe 2 and an installation component, the installation component comprising an adapter 3, a sleeve joint 4, a corrugated pipe 5 and a locking member 6, the locking member 6 comprising an embedded block 61, an ejection spring 62, a pressing component 63 and a protective component 64, the pressing component 63 comprising a pressing member 631 and a pushing member 632, the protective component 64 comprising a sliding sleeve 641, a connecting bracket 642 and an extrusion spring 643, the above-mentioned solution solves the problem that as the use time and the continuous filtering work are carried out, the operator needs to regularly check, maintain and even replace and repair the purification and filtering device at the designated position, the existing purification and filtering device mostly uses a flange to connect the interface with the pipeline, so when the user replaces it, he needs to wear the corresponding disassembly tool to disassemble the installed bolts, during the process of disassembling the bolts, due to the influence of the use time and the outdoor environment, it is easy for the bolts to rust, etc., so that the operator cannot quickly disassemble the bolts during disassembly, resulting in the problem that the entire disassembly and installation process takes a lot of time.

[0031] Furthermore, the two rotating tubes 2 are rotatably installed on both sides of the purification box body 1, the adapter 3 is installed on the pipe that needs to be connected, the sleeve joint 4 is connected to the adapter 3, the corrugated tube 5 is installed on the sleeve joint 4 and connected to the rotating tube 2, and the locking member 6 is connected to the sleeve joint 4 for installing the sleeve joint 4 on the adapter 3.

[0032] Specifically, the purification box body 1 is the main structure for purifying sewage. The purification box body 1 is provided with corresponding filter layers and adsorption layers to remove impurities from the sewage passing through. The water inlet and outlet ends provided on both sides of the purification box body 1 are rotatably mounted with the swivel pipe 2. The swivel pipe 2 is provided with a corresponding rotating mechanism so that the swivel pipe 2 can be rotated around a specified direction after connection, so that the user can complete the connection of pipes at different positions;

[0033] The adapter 3 is installed with the pipe to be connected through flanges and bolts. The installation method using the adapter 3 can greatly enhance the applicability of the entire device, and can be installed without changing the original water pipe connection method. The adapter 3 is provided with three connection ends in total. The middle connection end is connected to the corresponding access pipe through a flange and a bolt structure, and the other two connection ends of the adapter 3 are used to install the sleeve joint 4. It should be noted that since sewage is mostly conducted in one direction during actual use, the user only needs to select a suitable end of the adapter 3 and the sleeve joint 4 for installation during installation, and then the sleeve joint 4 is connected to the rotating pipe 2 through the provided corrugated pipe 5, thereby realizing the introduction of water into the purification box body 1, and after the imported sewage is purified in the purification box body 1, the water can be introduced into another pipe through the other side of the adapter 3 and the sleeve joint 4 and other same installation structures.

[0034] Furthermore, the embedded card block 61 is installed in the sleeve joint 4; the two sides of the ejection spring 62 are respectively connected to the embedded card block 61 and the sleeve joint 4; the pressing component 63 is connected to the sleeve joint 4, and is used to drive the embedded card block 61 to move in a specified direction; the protective component 64 is connected to the adapter 3, and is used to shield and protect the matching groove on the outside of the adapter 3.

[0035] Furthermore, the pressing member 631 is slidably mounted on the sleeve joint 4 ; the pushing member 632 is rotationally connected to the pressing member 631 , and is rotationally connected to the embedded block 61 .

[0036] Furthermore, the sliding sleeve 641 is arranged on one side of the adapter 3; the connecting bracket 642 is slidingly connected to the sliding sleeve 641 and fixedly installed on one side of the adapter 3; the two sides of the extrusion spring 643 are respectively connected to the sliding sleeve 641 and the connecting bracket 642, and the extrusion spring 643 is installed in the sliding sleeve 641.

[0037] When the present embodiment is in use, each of the sleeve joints 4 is provided with two embedded card blocks 61, and the two embedded card blocks 61 are installed on the inner boss provided on the sleeve joint 4. The side of the adapter 3 used to connect with the sleeve joint 4 is provided with a corresponding slide groove so that the sleeve joint 4 can be directly sleeved on the corresponding side of the adapter 3. At the same time, the slide grooves on both sides of the adapter 3 are also provided with embedded card grooves for cooperating with the embedded card blocks 61, and the back side of each embedded card block 61 is provided with the ejector Spring 62, when the sleeve joint 4 and the corresponding side of the adapter 3 are inserted into each other, the two ejection springs 62 provided inside the sleeve joint 4 squeeze the embedding block 61 to cooperate with the embedding groove provided on the adapter 3 to complete the installation limit of the sleeve joint 4 and the corresponding end of the adapter 3. It should be noted that in order to ensure the sealing performance between the sleeve joint 4 and the adapter 3, the user can set a sealing gasket of a corresponding shape at the position where the sleeve joint 4 and the adapter 3 are matched;

[0038] The two sides of the sleeve joint 4 are also provided with corresponding pressing pieces 631, and the pressing pieces 631 are connected with the designated embedded card block 61 through the pushing pieces 632. The two sides of the pushing pieces 632 and the pressing pieces 631 and the embedded card block 61 can all keep rotating. When the user presses the pressing pieces 631 to move, the pushing pieces 632 can drive the embedded card block 61 to be retracted under the action of the pressing pieces 631, so that when the user needs to disassemble the sleeve joint 4, the two embedded card blocks 61 can be retracted directly by pressing the pressing pieces 631 on both sides of the sleeve joint 4 and cooperating with the pushing pieces 632, so that the sleeve joint 4 can be directly disassembled from the designated side of the adapter 3. In order to facilitate the user to press the pressing pieces 631 on both sides at the same time, the sleeve joint 4 is also provided with corresponding bosses, so that the user can buckle the corresponding bosses with his fingers to exert force during the pressing process;

[0039] A corresponding arc platform is provided on the front side of the embedded card block 61. When the user installs the sleeve joint 4, the embedded card block 61 will be squeezed by the side wall of the adapter 3 due to the arc platform provided on the front side, so that the user can directly sleeve and clamp it during installation. At the same time, the slide grooves on both sides of the adapter 3 cooperate with the internal boss of the sleeve joint 4, which can facilitate the user to quickly judge and align the installation angle and position of the sleeve joint 4. In addition, the use of the corrugated tube 5 for the sleeve joint 4 to cooperate with the rotating tube 2 can facilitate the user to adjust the installation position of the sleeve joint 4 according to the actual installation situation.

[0040] Furthermore, the sliding sleeve 641 is arranged on one side of the adapter 3; the connecting bracket 642 is slidingly connected to the sliding sleeve 641 and fixedly installed on one side of the adapter 3; the two sides of the extrusion spring 643 are respectively connected to the sliding sleeve 641 and the connecting bracket 642, and the extrusion spring 643 is installed in the sliding sleeve 641.

[0041] When the present embodiment is in use, the positions where the two sides of the rotating member are connected are sleeved with the sliding sleeves 641, and the corresponding connecting brackets 642 are arranged on both sides of each sliding sleeve 641 for cooperation, so as to assist the sliding sleeve 641 in moving. At the same time, the extrusion spring 643 is also installed on the connecting bracket 642. When the corresponding end of the adapter 3 is not engaged, the sliding sleeve 641 can move under the action of the extrusion spring 643, thereby shielding and protecting the slots where the adapter 3 and the sleeve joint 4 are engaged, avoiding In order to prevent excessive impurities from accumulating inside the matching slot and thus affecting the subsequent installation, when the user is installing, the sliding sleeve 641 will slide on the adapter 3 due to the extrusion of the sleeve joint 4. When the sleeve joint 4 is installed, the extrusion spring 643 connected to the sliding sleeve 641 will be in a compressed state. At this time, when the user subsequently disassembles, the sliding sleeve 641 can also cooperate with the extrusion spring 643 to apply a certain thrust to the sleeve joint 4 after the limit is lost, so that it is more convenient to disassemble the sleeve joint 4.

[0042] Preferably, the mounting assembly also includes a reversing member 7, a movable toothed belt 8 and a conversion component 9, the conversion component 9 includes a transmission gear shaft 91, a drive gear shaft 92, a steering handle 93 and a locking component 94, and the locking component 94 includes a slot wheel 941, a movable locking plate 942, an ejection spring 943 and a cam turn handle 944.

[0043] Furthermore, the reversing member 7 is slidably installed in the adapter 3; the movable toothed belt 8 is fixedly installed on the top of the reversing member 7; the conversion member 9 is connected to the adapter 3, and is used to drive the movable toothed belt 8 and thereby drive the reversing member 7 to move.

[0044] Furthermore, the conversion component 9 includes a transmission gear shaft 91, a drive gear shaft 92, a steering handle 93 and a locking component 94, the transmission gear shaft 91 is engaged with the movable toothed belt 8 and is rotatably installed in the adapter 3; the drive gear shaft 92 is engaged with the transmission gear shaft 91 and is rotatably installed in the adapter 3; the steering handle 93 is fixedly connected to the drive gear shaft 92 and is located on the outside of the adapter 3; the locking component 94 is connected to the adapter 3 and is used to limit the drive gear shaft 92.

[0045] When the present embodiment is in use, the switching member 7 is slidably installed in the adapter 3, and two identical "L"-shaped guide grooves are provided on both sides of the switching member 7. When the switching member 7 moves to the designated position on the left, the "L"-shaped guide groove on the left side of the switching member 7 will guide the introduced water out from the left side of the adapter 3. Conversely, when the switching member 7 moves to the designated position on the right, the "L"-shaped guide groove on the left side of the switching member 7 will guide the introduced water out from the right side of the adapter 3. In this way, the user can control the guide direction of the adapter 3 by controlling the movement of the switching member 7, and then when the user needs to adjust the net When the purification box body 1 is replaced, the new purification box body 1 can be first installed by matching the sleeve joint 4 with the corresponding structure and the joint at the other end of the adapter 3, and then the water flow direction of the adapter 3 is controlled to flow and purify water from the new purification box body 1, while the purification box body 1 on the other side can be disassembled accordingly. In this way, when the user disassembles and replaces the purification box body 1 that needs to be replaced and maintained, it can be disassembled and assembled without affecting the normal purification of sewage, making the entire disassembly process more convenient and having less impact on normal drainage purification;

[0046] The top of the reversing member 7 is provided with a mounting groove for installing the mobile toothed belt 8. The mobile toothed belt 8 meshes with the corresponding gear on the transmission gear shaft 91. At the same time, the gear on the driving gear shaft 92 also meshes with the corresponding gear on the transmission gear shaft 91. The driving gear shaft 92 is driven by the provided steering handle 93, so that the user can drive the driving gear shaft 92 to rotate by operating the steering handle 93, and then the driving of the reversing member 7 is completed by the transmission gear shaft 91 cooperating with the mobile toothed belt 8. The steering handle 93 is a straight handle. Through the adjustment of the transmission direction by the transmission gear shaft 91 and the specified gear ratio between the transmission gear shaft 91 and the driving gear shaft 92, the user can realize that the steering handle points in the same direction as the transmission direction, so that the user can directly judge the transmission direction by the steering of the steering handle when operating.

[0047] Furthermore, the slot wheel 941 is fixedly mounted on the driving gear shaft 92; the movable card plate 942 is slidably mounted on the side of the adapter 3 close to the slot wheel 941; the two sides of the ejection spring 943 are respectively connected to the movable card plate 942 and the adapter 3; the cam turn handle 944 is rotatably mounted on the side of the adapter 3 close to the movable card plate 942.

[0048] When the present embodiment is in use, the slot wheel 941 is fixedly sleeved on the shaft of the driving gear shaft 92, and two corresponding slots are arranged on the slot wheel 941, and the slots arranged on the slot wheel 941 are adapted to the movable card plate 942, and the movable card plate 942 matches the movable slot arranged inside the adapter 3, and the back side of the movable card plate 942 is provided with the ejection spring 943. When the slot of the slot wheel 941 corresponds to the movable card plate 942 due to the rotation of the driving gear shaft 92, the movable card plate 942 can cooperate with the corresponding slot through the ejection spring 943, thereby locking the slot wheel 941 and the driving gear shaft 92 to avoid uncontrollable sliding of the reversing member 7 due to the misrotation of the driving gear shaft 92. The two slots arranged on the slot wheel 941 just correspond to the rotation positions on both sides of the steering handle 93, so that the two rotation positions of the driving gear shaft 92 can be limited according to actual conditions;

[0049] The cam handle 944 is composed of a camshaft at the end and a rotating handle for driving. The camshaft at the end of the cam handle 944 cooperates with the movable card plate 942. When the cam on the camshaft rotates, the movable card plate 942 will move accordingly under the squeezing of the cam, thereby causing the movable card plate 942 to disengage from the slot on the slot wheel 941. In this way, when the user needs to make adjustments, he can first drive the movable card plate 942 to move by turning the rotating handle, and then turn the steering handle 93. It should be noted that the distance moved by the movable card plate 942 is not enough for the cam handle 944 to perform a complete circular motion, so that the user can better grasp the rotation range of the cam handle 944 when driving the cam handle 944, and when the cam handle 944 is rotated to the extreme position, the movable card plate 942 will just be completely retracted.
