Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and specifically provides a water purifier. Background Technology

[0002] With the continuous improvement of people's living standards and the increasing attention people pay to the quality of water used, household water purifiers have become a common appliance in most families.

[0003] Existing water purifier filter cartridges consist of a body and a cap. The cap is integrated into the purifier's body, and the body and cap are fixedly connected by internal and external threads at the joint. The filter cartridge is installed inside the filter cartridge. When replacing the filter cartridge, the body must be unscrewed to separate it from the cap, and then the filter cartridge can be removed and replaced. Because the filter cartridge needs to withstand a certain water pressure, the body and cap must be tightly screwed together to ensure a good seal. Both opening and closing the body and cap require considerable force, making disassembly and assembly difficult and inconvenient for filter cartridge replacement.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the filter replacement of existing water purifiers is difficult.

[0006] This utility model provides a water purifier, which includes a housing, a water inlet pipe, a filter bottle, and a support base disposed within the housing. The water inlet pipe is detachably connected to the filter bottle. The filter bottle is located between the water inlet pipe and the support base. A first shaft is formed on one of the opposing surfaces of the support base and the filter bottle, and a first concave structure is formed on the other. A protrusion is also provided on the first surface where the first shaft is located. The first concave structure includes a first hole. A rotating groove adapted to the protrusion is also formed on the second surface where the first hole is located. The starting end of the rotating groove communicates with the first concave structure so that the protrusion can slide into the rotating groove and slide relative to the rotating groove to the end of the rotating groove during the rotation of the first shaft relative to the first hole. A second shaft is formed on one of the opposing surfaces of the support base and the side plate of the housing, and a second concave structure is formed on the other. The second concave structure includes a second hole. The support base is configured such that during the rotation of the first shaft relative to the first hole, the second shaft rotates relative to the second hole.

[0007] In the preferred embodiment of the above-mentioned water purifier, the first concave structure includes a first groove extending from the first hole to the edge of the second surface; the starting end of the rotating groove is located in the first groove, so that the first shaft and the protrusion can move through the first groove to the first hole and the starting end of the rotating groove respectively, or the starting end of the rotating groove is located in the connecting groove connected to the first hole, so that the first shaft can move through the first groove to the first hole, and the protrusion can move sequentially through the first groove, the first hole and the connecting groove to the starting end of the rotating groove.

[0008] In the preferred embodiment of the water purifier described above, a backstop structure is provided near the end of the rotating groove. The backstop structure is used to restrict the protrusion from sliding in the opposite direction when the protrusion slides to the end of the rotating groove relative to the rotating groove.

[0009] In the preferred embodiment of the above-mentioned water purifier, the anti-reverse structure includes an elastic limiting member disposed near the end of the rotating groove. During the assembly of the support base and the filter bottle, at least a portion of the elastic limiting member can deform when subjected to a pressing force greater than a set value by the protrusion, causing the protrusion to pass over the elastic limiting member. After the protrusion passes over the elastic limiting member, the elastic limiting member restores its deformation and restricts the protrusion to the end of the rotating groove.

[0010] In the preferred embodiment of the water purifier described above, the elastic limiting member includes an elastic element connected to the support base and a limiting block connected to the elastic element.

[0011] In the preferred embodiment of the water purifier described above, the elastic element is a spring piece whose end is suspended at the bottom of the rotating groove, and the limiting block is disposed near the end of the spring piece.

[0012] In the preferred embodiment of the above-mentioned water purifier, the first hole is formed on the surface of the support base opposite to the filter bottle, and the first shaft is formed on the surface of the filter bottle opposite to the support base; the second hole is formed on the surface of the support base away from the filter bottle, and the second shaft is formed on the side plate of the housing opposite to the support base.

[0013] In the preferred technical solution of the above-mentioned water purifier, both the first hole and the second hole are through holes, and the first hole and the second hole are connected to each other.

[0014] In the preferred embodiment of the water purifier described above, the filter bottle is connected to the water pipe in a plug-in configuration.

[0015] When the above technical solution is adopted, the water purifier includes a housing, a water pipe, a filter bottle, and a support base disposed within the housing. The water pipe and the filter bottle are detachably connected. The filter bottle is located between the water pipe and the support base. A first shaft is formed on one of the opposing surfaces of the support base and the filter bottle, and a first concave structure is formed on the other. A protrusion is also provided on the surface where the first shaft is located. The first concave structure includes a first hole. A rotating groove adapted to the protrusion is also formed on the surface where the first hole is located. The beginning of the rotating groove communicates with the first concave structure so that the protrusion can slide into the rotating groove and slide relative to the rotating groove to the end of the rotating groove during the rotation of the first shaft relative to the first hole. A second shaft is formed on one of the opposing surfaces of the support base and the side plate of the housing, and a second concave structure is formed on the other. The second concave structure includes a second hole. The support base is configured such that during the rotation of the first shaft relative to the first hole, the second shaft rotates relative to the second hole.

[0016] When the filter cartridge needs to be replaced, first remove the filter bottle, and then install the new filter bottle. To remove the filter bottle, first rotate the support base relative to the filter bottle around the axis of the first shaft and the first hole by a certain angle. During this process, the protrusion moves along the rotating groove to the beginning of the rotating groove. Then move the support base so that the protrusion and the first shaft slide out of the rotating groove and the first hole respectively to the outside of the support base, and the second shaft slides out of the second hole to the outside of the support base, thus separating the support base from the filter bottle and removing the support base. Finally, separate the filter bottle from the water pipe connection. To install the new filter bottle, first connect the filter bottle to the water pipe connection. Then move the support base to the position of the end of the filter bottle away from the water pipe connection, so that the protrusion and the first shaft move to the beginning of the rotating groove and the first hole respectively, and the second shaft moves into the second hole. Finally, rotate the support base relative to the filter bottle in the opposite direction (opposite to the rotation direction of the support base when removing the filter bottle) by a certain angle. During this process, the protrusion moves along the rotating groove to the end of the rotating groove, and the new filter bottle is installed in place.

[0017] This design allows for easy and convenient disassembly and replacement of the filter bottle, and consequently, the filter cartridge, without removing the cartridge from the bottle. This solves the problem of difficult cartridge replacement in existing water purifiers, optimizing the user experience. The filter bottle is detachably connected to the water pipe, and the support base is positioned at the end of the filter bottle furthest from the water pipe, ensuring reliable filter bottle fixation. The second shaft and second hole work together to define the position of the support base relative to the side plate of the housing, effectively guaranteeing the position of the support base and filter bottle within the housing and improving the connection stability of the filter bottle.

[0018] Preferably, a backstop structure is provided near the end of the rotating groove. The backstop structure is used to restrict the protrusion from sliding in the opposite direction when the protrusion slides relative to the end of the rotating groove.

[0019] With this design, when the support base and filter bottle are in place, the anti-reverse structure can limit the position of the protrusion, thereby preventing the support base from rotating relative to the filter bottle due to vibration, making the connection between the support base and the filter bottle more stable.

[0028] like Figures 1 to 12As shown, the water purifier includes a housing 1 with an opening 11 on its side and an openable / closable door 12. Inside the housing 1 is a water circuit section and two filter bottles 5. The water circuit section includes two water circuit plates 2, a water circuit adapter 3, and a control valve assembly 4. The two water circuit plates 2 are located in the upper part of the housing 1. Each water circuit plate 2 includes two water circuit connectors 21. The first ends of the two water circuit connectors 21 of the second water circuit plate 2 are respectively connected to the second ends of the two water circuit connectors 21 of the first water circuit plate 2 via quick-connect fittings. The two filter bottles 5 are respectively located below the two water circuit plates 2. Each water circuit connector 21 has a first pipe connector 22 on its lower side, and the filter bottle 5 has a second pipe connector 51 at its upper end. The first pipe connector 22 and the second pipe connector 51 are connected by insertion. The first pipe connector 22 is inserted into the second pipe connector 51. An annular groove 221 is formed on the outer peripheral wall of the first pipe connector 22. Two horizontally extending insertion holes 511 are formed on the side wall of the second pipe connector 51. The two insertion holes 511 are symmetrical about the axis of the second pipe connector 51. The two insertion holes 511 extend from the outer wall surface of the second pipe connector 51 to the inner wall surface and are aligned with the annular groove 221. The locking member 7 includes a connecting rod 71 and two insertion rods 72 extending from both ends of the connecting rod 71 in a direction perpendicular to the connecting rod 71. The two insertion rods 72 are respectively inserted into the two insertion holes 511 and into the annular groove 221, thereby locking the first pipe connector 22 into the second pipe connector 51 through the cooperation of the locking member 7 with the insertion holes 511 and the annular groove 221.

[0029] The water flow adapter 3 has two water flow channels (not shown in the figure). The two ends of each water flow channel are perpendicular to each other. The first end of the two water flow channels in the water flow adapter 3 is connected to the second end of the two water flow connectors 21 of the second water flow plate 2 by quick connector. The two water flow interfaces of the control valve assembly 4 are respectively connected to the second end of the water flow channels in the water flow adapter 3. The control valve assembly 4 is located on one side of the filter bottle 5.

[0030] A support base 6 is provided below the filter bottle 5; a first shaft 52 and a first concave structure are respectively formed on the opposing surfaces of the support base 6 and the filter bottle 5. A protrusion 53 is also provided on the first surface 5a where the first shaft 52 is located. The first concave structure includes a first hole 61. A rotating groove 63 adapted to the protrusion 53 is also formed on the second surface 6a where the first hole 61 is located. The beginning of the rotating groove 63 is connected to the first concave structure so that the protrusion 53 can slide into the rotating groove 63 and slide to the end of the rotating groove 63 during the rotation of the first shaft 52 relative to the first hole 61. Specifically, the first concave structure includes a first groove extending from the first hole 61 to the edge of the second surface 6a; the starting end of the rotating groove 63 is located in the first groove so that the first shaft 52 and the protrusion 53 can move through the first groove to the starting end of the first hole 61 and the rotating groove 63 respectively, or the starting end of the rotating groove 63 is located in the connecting groove connected to the first hole 61 so that the first shaft 52 can move through the first groove to the first hole 61, while the protrusion 53 can move sequentially through the first groove, the first hole 61 and the connecting groove 64 to the starting end of the rotating groove 63.

[0031] In this embodiment, the first groove is a first straight groove 62, and the starting end of the rotating groove 63 is located in the connecting groove 64 connected to the first hole 61. The first surface 5a is the lower end surface of the filter bottle 5, the second surface 6a is the upper surface of the support base 6, the first shaft 52 is formed on the lower end surface of the filter bottle 5, and the first hole 61, the first straight groove 62, the rotating groove 63 and the connecting groove 64 are formed on the upper surface of the support base 6. The first straight groove 62 extends from the first hole 61 to the edge of the upper surface of the support base 6.

[0032] On one of the opposing surfaces of the support base 6 and the side plate of the housing 1, a second shaft 13 is formed, while on the other, a second recessed structure is formed, the second recessed structure including a second hole 65; the support base 6 is configured such that, while the first shaft 52 rotates relative to the first hole 61 within the first hole 61, the second shaft 13 rotates relative to the second hole 65 within the second hole 65. In this embodiment, the side plate of the housing 1 opposite to the support base 6 is the bottom plate of the lower side of the housing 1, the second shaft 13 is formed on the upper surface of the bottom plate of the housing 1, and the second hole 65 is on the lower surface of the support base 6. A second straight groove 66 extending from the second hole 65 to the edge of the lower surface of the support base 6 is also formed on the lower surface of the support base 6.

[0033] In this embodiment, both the first hole 61 and the second hole 65 are through holes, and the first hole 61 and the second hole 65 are connected to each other. The first straight groove 62 and the second straight groove 66 are connected to each other in the axial direction (i.e., the vertical direction) of the first hole 61.

[0034] Furthermore, a stop structure is provided near the end of the rotating groove 63. The stop structure is used to restrict the protrusion 53 from sliding backward relative to the end of the rotating groove 63. Specifically, the stop structure includes an elastic limiting member provided near the end of the rotating groove 63. During the assembly of the support 6 and the filter bottle 5, at least a portion of the elastic limiting member can deform when the pressing force of the protrusion 53 is greater than a set value, causing the protrusion 53 to pass over the elastic limiting member. After the protrusion 53 passes over the elastic limiting member, the elastic limiting member returns to its original deformation, thus limiting the protrusion 53 to the end of the rotating groove 63. The elastic limiting member includes an elastic element connected to the support 6 and a limiting block 632 connected to the elastic element. In this embodiment, the elastic element is a spring piece 631 whose end is suspended at the bottom of the rotating groove 63, and the limiting block 632 is provided near the end of the spring piece 631.

[0035] When it is necessary to remove the filter bottle 5, open the door 12, and first rotate the support base 6 counterclockwise by 90° relative to the filter bottle 5 around the axis of the first shaft 52 and the first hole 61 (in Figure 10 (The angle shown) During this process, the protrusion 53 moves along the rotating groove 63 toward the beginning of the rotating groove 63. The protrusion 53 contacts the limiting block 632. The limiting block 632 is squeezed by the protrusion 53, causing the end of the spring piece 631 to move downward, thereby causing the limiting block 632 to move downward. After the protrusion 53 passes the limiting block 632, the end of the spring piece 631 moves upward to reset, thereby causing the limiting block 632 to reset. The protrusion 53 continues to move along the rotating groove 63 toward the beginning of the rotating groove 63. Finally, the protrusion 53 moves to the beginning of the rotating groove 63 and enters the connecting groove 64. Then, the support 6 moves horizontally along the edge of the first straight groove 62 located on the upper surface of the support 6 toward the other end of the first straight groove 62. First, shaft 52 slides from the first hole 61 into the first straight groove 62 and then slides out from the first straight groove 62. Protrusion 53 first slides along the connecting groove 64 into the first hole 61, then slides from the first hole 61 into the first straight groove 62, and finally slides out from the first straight groove 62. At the same time, second shaft 13 first slides from the second hole 65 into the second straight groove 66 and then slides out from the second straight groove 66, thereby separating the support base 6 from the filter bottle 5 and the bottom plate of the housing 1 and removing the support base 6. Finally, the insertion rod 72 of the locking member 7 is pulled out from the annular groove 221 and the insertion hole 511, and then the filter bottle 5 is moved downward. The second pipe joint 51 at the upper end of the filter bottle 5 separates from the first pipe joint 22 on the lower side of the water pipe 21, and the filter bottle 5 is moved out of the housing 1 from the opening 11. It should be noted that before disassembling the support base 6, the insertion rod 72 of the locking member 7 can be pulled out from the annular groove 221 and the insertion hole 511, and then the support base 6 can be disassembled. Finally, the filter bottle 5 is moved downward so that the second pipe joint 51 at the upper end of the filter bottle 5 is separated from the first pipe joint 22 on the lower side of the water pipe 21.

[0036] When it is necessary to install the filter bottle 5, first move the filter bottle 5 into the housing 1 from the opening 11, aligning the second pipe connector 51 at the upper end of the filter bottle 5 with the first pipe connector 22 on the lower side of the water pipe 21. Move the filter bottle 5 upwards, inserting the second pipe connector 51 at the upper end of the filter bottle 5 into the first pipe connector 22 on the lower side of the water pipe 21. Then insert the locking rod 72 into the insertion hole 511 and the annular groove 221. Then, along the first straight groove 6, the end of the support base 6 located in the middle of the upper surface of the support base 6 faces the other end of the first straight groove 62. The direction moves horizontally. Protrusion 53 first slides into the first straight groove 62, then from the first straight groove 62 into the first hole 61, and finally from the first hole 61 into the connecting groove 64 and slides to the beginning of the rotating groove 63. First shaft 52 first slides into the first straight groove 62 and then from the first straight groove 62 into the first hole 61. Second shaft 13 first slides into the second straight groove 66 and then from the second straight groove 66 into the second hole 65. Finally, the support base 6 rotates 90° clockwise relative to the filter bottle 5 about the axis of the first shaft 52 and the first hole 61. Figure 10 (As shown in the angle), during this process, the protrusion 53 moves along the rotating groove 63 toward the end of the rotating groove 63. The protrusion 53 contacts the limiting block 632. The limiting block 632 is squeezed by the protrusion 53, causing the end of the spring piece 631 to move downward, thereby causing the limiting block 632 to move downward. After the protrusion 53 passes the limiting block 632, the end of the spring piece 631 moves upward to reset, thereby causing the limiting block 632 to reset. The protrusion 53 stays at the end of the rotating groove 63 and is restricted in its movement by the limiting block 632 and the end of the rotating groove 63. The filter bottle 5 is installed in place.

[0037] This design allows for easy and convenient disassembly and replacement of filter bottle 5, which in turn enables the replacement of the filter element without removing it from filter bottle 5. This solves the problem of difficult filter element replacement in existing water purifiers and optimizes the user experience.

[0038] The support base 6 and the side plate of the housing 1 are respectively formed with a second shaft 13 and a second concave structure. The second concave structure includes a second hole 65. The support base 6 is configured such that when the first shaft 52 rotates relative to the first hole 61 while it is inside the first hole 61, the second shaft 13 rotates relative to the second hole 65 while it is inside the second hole 65. This limits the position of the support base 6 relative to the bottom plate of the housing 1, and more effectively ensures the position of the support base 6 and the filter bottle 5 in the housing 1, thereby improving the connection stability of the filter bottle 5.

[0039] The first pipe connector 22 is inserted into the second pipe connector 51. An annular groove 221 is formed on the outer peripheral wall of the first pipe connector 22. Two horizontally extending insertion holes 511 are formed on the side wall of the second pipe connector 51. The two insertion holes 511 are symmetrical about the axis of the second pipe connector 51, extending from the outer wall surface to the inner wall surface of the second pipe connector 51 and aligned with the annular groove 221. The locking member 7 includes a connecting rod 71 and a locking mechanism extending from both ends of the connecting rod 71 towards a point perpendicular to the connecting rod 71. Two insert rods 72 extend in the direction of insertion. The two insert rods 72 are respectively inserted into two sockets 511 and into annular grooves 221. Thus, the locking member 7 locks the first pipe connector 22 into the second pipe connector 51 through the cooperation of the sockets 511 and annular grooves 221. After the first pipe connector 22 and the second pipe connector 51 are connected, the connection reliability between the first pipe connector 22 and the second pipe connector 51 is improved by the cooperation of the locking member 7 with the sockets 511 and annular grooves 221.

[0040] The water system includes two water system panels 2, a water system adapter 3, and a control valve assembly 4. The first ends of the two water system connectors 21 of the second water system panel 2 are connected to the second ends of the two water system connectors 21 of the first water system panel 2 via quick-connect fittings. The first ends of the two water flow channels within the water system adapter 3 are connected to the second ends of the two water system connectors 21 of the second water system panel 2 via quick-connect fittings. The two water system interfaces of the control valve assembly 4 are respectively connected to the second ends of the water flow channels within the water system adapter 3. This facilitates the assembly and disassembly of the water system panels 2, the water system adapter 3, and the control valve assembly 4. The water system connectors 21 are integrated onto the water system panel 2, making their structure more compact.

[0041] The control valve assembly 4 is located on one side of the filter bottle 5. Compared with the control valve assembly 4 being located above the filter bottle 5, this can reduce the overall height of the water purifier, thus facilitating the installation of the water purifier.

[0042] It should be noted that the second shaft 13 is formed on the upper surface of the bottom plate of the housing 1, and the second hole 65 and the second straight groove 66 are formed on the lower surface of the support base 6. This is only a specific arrangement and can be adjusted in actual applications. For example, in another arrangement, the second shaft 13 is formed on the lower surface of the support base 6, and the second hole 65 and the second straight groove 66 are formed on the upper surface of the bottom plate of the housing 1. The second shaft 13 and the second hole 65 are coaxial with the first shaft 52 and the first hole 61. The projection of the end of the second straight groove 66 away from the second hole 65 on the horizontal plane coincides with the projection of the end of the first straight groove 62 away from the first hole 61 on the horizontal plane. In addition, the first shaft 52 is formed on the lower end face of the filter bottle 5, and the first hole 61, the first straight groove 62, the rotating groove 63 and the connecting groove 64 are formed on the upper surface of the support base 6. This is also a preferred arrangement. In practical applications, it can be adjusted. For example, in another arrangement, the first shaft 52 is formed on the upper surface of the support base 6, and the first hole 61, the first straight groove 62, the rotating groove 63 and the connecting groove 64 are formed on the lower end face of the filter bottle 5. Furthermore, the bottom of the rotating groove 63 is a spring piece 631 with its end suspended, and the limiting block 632 is located near the end of the spring piece 631. This is also a specific arrangement, which can be adjusted in practical applications. For example, in another arrangement, the bottom of the rotating groove 63 is fixed, and a mounting hole is provided near the end of the bottom of the rotating groove 63. A spring is installed in the mounting hole, and the lower end of the limiting block 632 is connected to the spring. The lower part of the limiting block 632 is located in the mounting hole, and the upper part of the limiting block 632 protrudes out of the mounting hole. The spring is in a compressed state. When the upper part of the limiting block 632 is subjected to... When external pressure is applied, the limiting block 632 compresses the spring and moves downward. When the external pressure on the upper part of the limiting block 632 disappears, the spring extends and moves the limiting block 632 back to its original position. In another configuration, the bottom of the rotating groove 63 is fixed, and the elastic limiting element is the limiting block 632 located near the end of the bottom of the rotating groove 63. The limiting block 632 is made of elastic material. When the upper part of the limiting block 632 is subjected to external pressure, at least a portion of the limiting block 632 is squeezed and deformed, moving downward. When the external pressure on the upper part of the limiting block 632 disappears, the limiting block 632 returns to its original deformation.

[0043] It should also be noted that the control valve assembly 4 is located on one side of the filter bottle 5. This is only a preferred arrangement and can be adjusted in practical applications. For example, in another arrangement, the control valve assembly 4 is located above the filter bottle 5. Furthermore, the water circuit includes two water circuit plates 2, a water circuit adapter 3, and the control valve assembly 4. This is only one specific arrangement and can be adjusted in practical applications. For example, in another arrangement, the water circuit only includes two water circuit plates 2, excluding the water circuit adapter 3 and the control valve assembly 4. Additionally, two filter bottles 5 are arranged inside the housing 1. This is only one specific arrangement and can be adjusted in practical applications. For example, one or three filter bottles 5 can be arranged inside the housing 1.

The first ramp surface extends away from the first hole 61 and away from the first axis 52. The second straight groove 66 is replaced by a surface portion at its location to form a second ramp surface connected to the second hole 65. The second ramp surface extends away from the second hole 65 and away from the second axis 13.

[0049] In another feasible embodiment, unlike the above embodiment, the second pipe connector 51 is inserted into the first pipe connector 22. An annular groove is formed on the outer peripheral wall of the second pipe connector 51. Two horizontally extending insertion holes are formed on the side wall of the first pipe connector 22. The two insertion holes are symmetrical about the axis of the first pipe connector 22. The two insertion holes extend from the outer wall surface of the second pipe connector 51 to the inner wall surface and are aligned with the annular groove. The locking member 7 includes a connecting rod 71 and two insertion rods 72 extending from both ends of the connecting rod 71 in a direction perpendicular to the connecting rod 71. The two insertion rods 72 are respectively inserted into the two insertion holes and into the annular groove, thereby locking the second pipe connector 51 into the first pipe connector 22 through the cooperation of the locking member 7 with the insertion holes and the annular groove.

[0050] In another feasible embodiment, unlike the above embodiment, the annular groove 221, insertion hole 511 and locking member 7 of the above embodiment are not provided. After the first pipeline connector 22 is inserted and connected to the second pipeline connector 51 at the upper end of the filter bottle 5, it is connected and supported at the lower part of the filter bottle 5 by the support seat 6, so that the first pipeline connector 22 and the second pipeline connector 51 remain in the inserted state.

[0051] In another feasible embodiment, unlike the above embodiment, the first pipe joint 22 and the second pipe joint 51 are mated and connected by a snap-fit ​​structure.

[0052] In another feasible embodiment, unlike the above embodiment, the water pipe plate 2 is not included, and the water pipes 21 are independent of each other.

[0053] In another feasible embodiment, unlike the above embodiment, the opening 11 is formed on the top of the housing 1, and the water pipe 21, the filter bottle 5 and the support base 6 are distributed in sequence along the horizontal direction.
