Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and in particular to a water circuit board device and a water purification equipment. Background Technology

[0002] With societal development, people have increasingly higher demands for water quality. Currently, water purification equipment refers to water treatment equipment that performs deep filtration and purification of water according to usage requirements. It can remove impurities from water (such as floating matter, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, etc.) and improve water quality. Water purification equipment is widely used in homes, offices, shopping malls, factories, and other places.

[0003] Water purification equipment typically consists of filter cartridges, a water circuit board, and a main body. The filter cartridge is installed inside the main body and connects to the water circuit board to achieve the filtration function. Since the filtration capacity of the filter cartridge decreases over time, it needs to be replaced periodically. Currently, replacement is achieved by rotating the filter cartridge: rotating it clockwise connects it to the water circuit board, while rotating it counterclockwise removes the filter cartridge from the water circuit board.

[0004] However, after water is introduced into the filter element, the friction between the filter element and the water circuit board increases under the action of water pressure, which makes the rotation of the filter element more difficult. This makes it more difficult to disassemble and assemble the filter element, resulting in a poor user experience. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0022] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0023] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 This is a schematic diagram of a water purification device 10 in a locked state according to an embodiment of the present invention. Figure 2 This is a schematic diagram of a water purification device 10 in a released state according to an embodiment of the present invention. Figure 3 This is a schematic diagram of a water purification device 10 in a disassembled state according to an embodiment of the present invention. Figure 4 yes Figure 1 The diagram shows a cross-sectional structure of the water purification device 10 along the A1-A2 position. Figure 5 yes Figure 2 The diagram shows a cross-sectional view of the water purification device 10 along the B1-B2 position. The water purification device 10 may include a filter cartridge 11 and a water circuit board 12. The water circuit board 12 may include a water channel structure 121, a water connector 122, and a drive mechanism 124. The water circuit board 12 has multiple flow channels internally to achieve directional distribution of water flow and physical connection of various functional modules (such as the filter cartridge 11, valves, and sensors). The filter cartridge 11 is used to intercept, adsorb, or convert impurities in the water to ensure that the output water meets standards. It is understood that... Figure 1 The water purification device 10 being in the locked state means that the filter element 11 and the water connector 122 in the water purification device 10 are in the connected state. Figure 2 The water purification device 10 being in a loose state means that the filter element device 11 and the water connector 122 in the water purification device 10 are in a separated state.

[0025] The water channel plate structure 121 has a first water passage s1; the water channel plate structure 121 has a plurality of first water pipes arranged side by side, each first water pipe having a first water passage s1, which can be connected to other mechanisms (such as booster pumps) in the water purification equipment 10.

[0026] The water connector 122 is slidably connected to the water channel plate structure 121. The water connector 122 has a second water channel s2 communicating with the first water channel s1. The water connector 122 is used for detachable connection with the filter element device 11. Part of the structure of the water connector 122 can be assembled in the first water channel s1 of the water channel plate structure 121, so that the water connector 122 and the water channel plate structure 121 are slidably connected. The first end of the water connector 122 can be slidably connected to the water channel plate structure 121, and the second end of the water connector 122 can be used for detachable connection with the filter element device 11 (not shown in the figure) of the water purification equipment 10. For example, the water connector 122 includes a plurality of second water pipes arranged side by side, each of the plurality of second water pipes corresponding one-to-one with a plurality of first water pipes. Each second water pipe has a second water channel s2, and the second water channel s2 can communicate with the filter element device 11 and the first water channel s1 respectively. The extension directions of the first water passage s1 and the second water passage s2 can be parallel, the sliding direction of the water connector 122 can be parallel to the extension direction of the first water passage s1, and the sliding direction of the water connector 122 can be perpendicular to the axial direction of the filter element device 11. It is understood that, in this embodiment, during the sliding process of the water connector 122, the water connector 122 can always maintain a connection with the water channel plate structure 121.

[0027] The drive mechanism 124 is rotatably connected to the water channel plate structure 121 and slidably connected to the water connector 122. The drive mechanism 124 is configured to extend or retract the water connector 122 during rotation relative to the water channel plate structure 121, thereby connecting or separating the water connector 122 from the filter element device 11. The drive mechanism 124 can also extend the second end of the water connector 122 from the water channel plate structure 121 to connect the water connector 122 to the filter element device 11, and can also retract the second end of the water connector 122 from the water channel plate structure 121 to separate the water connector 122 from the filter element device 11. The filter element device 11 may have an assembly connector 112 to which the water connector 122 can be detachably inserted.

[0028] For example, the drive mechanism 124 may include an electric drive mechanism 124 or a manual drive mechanism 124. When the drive mechanism 124 is an electric drive mechanism 124, the operator can activate the drive mechanism 124 via a control button, causing the drive mechanism 124 to slide the water connector 122. When the drive mechanism 124 is a manual drive mechanism 124, the operator can manually control the drive mechanism 124 to slide the water connector 122.

[0029] In this embodiment of the invention, the water channel plate structure 121 and the water channel connector 122 in the water channel plate device 12 are slidably connected, and the water channel connector 122 is used to connect with the filter element device 11 in the water purification equipment 10. Thus, when it is necessary to disassemble and replace the filter element device 11, the operator controls the drive mechanism 124 to move the water channel connector 122 away from the filter element device 11, thereby separating the water channel connector 122 from the filter element device 11. When it is necessary to connect the filter element device 11 to the water channel plate device 12 in the water purification equipment 10, the operator controls the drive mechanism 124 to move the water channel connector 122 towards the filter element device 11, thereby installing the filter element device 11 and the water channel plate device 12, and achieving water channel connection between the filter element device 11 and the water channel plate device 12. Thus, when the filter cartridge device 11 is disassembled and installed from the water purification equipment 10 using the above structure, it is only necessary to extend and retract the filter cartridge by means of the drive mechanism 124 and the water connector 122. There is no need to rotate the filter cartridge, so that the filter cartridge does not have to bear the overall weight of the filter cartridge. This makes disassembling and installing the filter cartridge easy and effortless, and improves the user experience.

[0030] Furthermore, after removing the filter element assembly 11 from the water purification equipment, only the filter element assembly 11 needs to be replaced, without replacing other parts such as the water channel plate assembly 121, which can reduce the operating cost of the water purification equipment.

[0031] In summary, this utility model embodiment provides a water channel plate device 12 including a water channel plate structure 121, a water channel connector 122, and a drive mechanism 124. The water channel plate structure 121 has a first water passage s1; the water channel connector 122 is slidably connected to the water channel plate structure 121 and has a second water passage s2 connected to the first water passage s1, and is used for detachable connection with the filter element device 11; the drive mechanism 124 is structurally movably connected to the water channel plate structure 121 and the water channel connector 122, and is configured to: drive the water channel connector 122 to extend or retract, so that the water channel connector 122 is connected or separated from the filter element device 11. When it is necessary to disassemble and replace the filter element device 11, the operator controls the drive mechanism 124 to drive the water channel connector 122 to retract, so as to separate the water channel connector 122 from the filter element device 11. When it is necessary to connect the filter cartridge 11 to the water circuit board 12 in the water purification equipment 10, the operator controls the drive mechanism 124 to extend the water circuit connector 122, thereby enabling the installation of the filter cartridge 11 and the water circuit board 12. In this way, the filter cartridge 11 can be installed and removed by linearly extending and retracting the water circuit connector 122, avoiding the need to rotate the filter cartridge, making the installation and removal of the filter cartridge easy and effortless, and improving the user experience.

[0032] Please refer to Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 6This is a schematic diagram of another water purification device 10 provided in this embodiment of the present invention. Figure 7 This is a schematic diagram of another water purification device 10 provided in this embodiment of the present invention. Figure 8 yes Figure 6 The schematic diagram of the cross-sectional structure of the water purification device 10 shown is as follows. Figure 9 yes Figure 7 The schematic diagram of the cross-section of the water purification device 10 shown shows that, Figure 6 and Figure 7 The diagram shown is a structural schematic of the water purification equipment 10 after the filter element 11 has been removed. Figure 6 The water connector 122 is in the retracted state. Figure 7 The water inlet connector 122 is in the extended state. In an optional embodiment, the drive mechanism 124 may include a manual handle structure, rotatably connected to the water channel plate structure 121 and movably connected to the water channel plate connector. The handle structure can be rotatably connected to the water channel plate structure 121 via a pivot, and can also be movably connected to the water channel plate connector via a sliding groove or linkage mechanism. When the operator rotates the handle structure, the handle structure can convert the rotational motion into linear motion, thereby causing the water inlet connector 122 to extend or retract.

[0033] Compared to electrically driven structures, handle structures offer advantages such as high reliability, simple maintenance, intuitive operation, no need for external power supply, low cost, and enhanced safety. Controlling the water circuit connector 122 through purely mechanical transmission avoids the complexity and potential failures of electronic components, thus improving the durability and economy of the water circuit board device 12.

[0034] Please refer to Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 , Figure 10 This is a schematic diagram of the structure of a water channel plate 121 and a water channel connector 122 provided in an embodiment of this utility model. Figure 11 yes Figure 10 The diagram shows an exploded view of the waterway plate structure 121 and the waterway connector 122. Figure 12 This is a schematic diagram of the structure of a drive mechanism 124 provided in an embodiment of the present invention. Figure 13 This is a cross-sectional structural diagram of a water purification device provided in an embodiment of this utility model. Figure 14This is a cross-sectional structural diagram of another water purification device provided in an embodiment of the present invention. In an optional embodiment, the water channel plate structure 121 may include a first water pipe 1211 and a rotating shaft 1212. A first water passage s1 is disposed in the first water pipe 1211. The rotating shaft 1212 is fixedly connected to the first water pipe 1211, and the extension direction of the rotating shaft 1212 is perpendicular to the extension direction of the first water pipe 1211. The rotating shaft 1212 is rotatably connected to the drive mechanism 124. For example, the water channel plate structure 121 may include four first water pipes 1211 arranged side by side and connected in sequence, and two rotating shafts 1212. The two rotating shafts 1212 are respectively fixedly installed on the outside of the two outermost first water pipes 1211.

[0035] In one optional embodiment, the water connector 122 may include a second water pipe 1221 and a positioning shaft 1222. A second water passage s2 is disposed within the second water pipe 1221, which is assembled within the first water pipe 1211. The positioning shaft 1222 is fixedly connected to the second water pipe 1221, and the extending direction of the positioning shaft 1222 is perpendicular to the extending direction of the second water pipe 1221. The positioning shaft 1222 extends out of the first water pipe 1211 and is movably connected to the drive mechanism 124. For example, the water channel plate structure 121 may include four second water pipes 1221 arranged side-by-side and connected sequentially, and two positioning shafts 1222. The two positioning shafts 1222 are respectively fixedly installed on the outer sides of the two outermost second water pipes 1221.

[0036] In an optional embodiment, the drive mechanism 124 may include a handle portion b1 and a transmission portion b2, which are fixedly connected. The transmission portion b2 is located outside the first water pipe 1211 and has a rotating hole k1 and a strip-shaped sliding hole k2. The rotating shaft 1212 is fitted into the rotating hole k1, and the positioning shaft 1222 is fitted into the sliding hole. For example, the drive mechanism 124 has two transmission portions b2, located on opposite sides of the water channel plate structure 121. The two ends of the handle portion b1 can be fixedly connected to the two transmission portions b2 respectively. The transmission portion b2 is connected to the rotating shaft 1212 of the water channel plate structure 121 through the rotating hole k1 and to the positioning shaft 1222 of the water connector 122 through the strip-shaped sliding hole k2, thus converting the rotational motion of the transmission component into linear motion, thereby causing the water connector 122 to extend or retract. When the filter element device 11 needs to be replaced, the operator rotates the handle b1 in one direction. During the rotation of the handle b1, the water connector 122 is driven to slide through the transmission part b2 to achieve connection or separation with the filter element device 11.

[0037] In one optional embodiment, the first water pipe 1211 has a strip-shaped mounting hole k3 on its side. A positioning shaft 1222 passes through the mounting hole k3. One end of the positioning shaft 1222 inside the mounting hole k3 is fixedly connected to the second water pipe 1221, and the other end of the positioning shaft 1222 outside the mounting hole k3 is movably connected to the transmission part b2. The extending direction of the strip-shaped mounting hole k3 is parallel to the extending direction of the first water pipe 1211, so that the positioning shaft 1222 can move in a direction parallel to the extending direction of the first water pipe 1211, thereby driving the second water pipe 1221 to extend and retract in a direction parallel to the extending direction of the first water pipe 1211.

[0038] In this embodiment of the invention, the rotation of the drive mechanism 124 drives the transmission unit b2 to rotate around the rotating shaft 1212. Simultaneously, the rotational motion is converted into linear motion through the cooperation of the strip-shaped sliding hole k2 and the positioning shaft 1222. This causes the second water pipe 1221 to extend or retract within the first water pipe 1211, thus extending or retracting the water connector 122. This ensures efficient and precise motion conversion, while the symmetrical arrangement of the two transmission units b2 enhances the synchronization and stability of the water connector 122's movement.

[0039] Furthermore, through the nested structure of the first water pipe 1211 and the second water pipe 1221 and the design of the guide mounting hole k3, the water circuit board assembly can simultaneously achieve both sealing and stable operation.

[0040] Please refer to Figure 9 and Figure 11 In an optional embodiment, the first water pipe 1211 further includes a first pipe segment d1 and a second pipe segment d2 connected together. The first pipe segment d1 has an inlet / outlet hole k4, and a mounting hole k3 is provided on the second pipe segment d2. The second water pipe 1221 includes a first end, a second end, and a sealing element 123 sleeved on the second end. The first end is used to connect with the filter element device 11, the second end is assembled in the second pipe segment d2, and the sealing element 123 is located between the second end and the second pipe segment d2. The first water pipe 1211 can communicate with other structures (such as a booster pump) in the water purification equipment 10 through the inlet / outlet hole k4. Thus, by setting a segmented first water pipe 1211, the difficulty of assembling the second water pipe 1221 into the first water pipe 1211 can be reduced. The second end of the second water pipe 1221 can communicate with the first water pipe 1211, and the sealing element 123 can be used to seal between the first water pipe 1211 and the second water pipe 1221.

[0041] Please refer to Figure 9 , Figure 10 and Figure 11In an optional embodiment, the seal 123 may include a first sealing ring 1231 and a second sealing ring 1232; both the first sealing ring 1231 and the second sealing ring 1232 are sleeved on the second end, and are arranged along the axial direction of the second water pipe 1221; in a direction parallel to the axial direction of the second water pipe 1221, when the second water pipe 1221 is extended, the first sealing ring 1231 is located between the inlet / outlet hole k4 and the mounting hole k3; when the second water pipe 1221 is retracted, at least one of the first sealing ring 1231 and the second sealing ring 1232 is located between the inlet / outlet hole k4 and the mounting hole k3. Thus, through this double sealing structure, the water pipe plate device 12 can maintain the seal of the first water passage s1 and the second water passage s2 when the water pipe connector 122 is in the extended or retracted state. For example, the outer wall of the second water pipe 1221 may have two annular grooves, and the first sealing ring 1231 and the second sealing ring 1232 may be installed in the two annular grooves respectively.

[0042] It is understood that in this embodiment of the present invention, the water purification device 10 has two filter cartridges 11 and two water connectors 122. The two water connectors 122 can be installed in the same water channel plate structure 121. The two water connectors 122 can move in opposite directions. The water channel plate structure 121 includes multiple connecting water channels. Some of the multiple connecting water channels can be used to connect the filter cartridges 11 and other structures in the water purification device 10. A partition is provided between two partially opposite connecting water channels. The multiple connecting water channels also include some connecting water channels used to connect the two filter cartridges 11.

[0043] Please refer to Figure 4 , Figure 15 and Figure 16 , Figure 15 This is a schematic diagram of the structure of a filter element device 11 provided in an embodiment of the present invention. Figure 16 This is a schematic diagram of the structure of a water connector 122 provided in an embodiment of the present invention. The filter element device 11 includes a filter element body 111, an assembly connector 112, and a one-way valve 113. The assembly connector 112 is connected to the filter element body 111, and its end has a plug-in port. The water circuit board assembly also includes a third sealing ring. The water connector 122 is detachably inserted into the plug-in port of the assembly connector 112. The third sealing ring is sleeved on the outside of the second water pipe 1221 of the water connector 122 and is located between the outer wall of the water connector 122 and the inner wall of the plug-in port. The one-way valve 113 is assembled in the assembly connector 112. When the water connector 122 is inserted into the assembly connector 112, the end of the water connector 122 abuts against the one-way valve 113, and the one-way valve 113 is open. When the water connector 122 is not inserted into the first water connector 122, the one-way valve 113 is closed.

[0044] For example, the water pipe connector 122 also includes a push rod 1223 fixed to one end of the second water pipe 1221. The push rod 1223 is used to open the one-way valve 113.
