[0026] Embodiment 1, as Figures 11 - 12 shown, the present application provides a water pipe assembly having an on-off function, including: A connecting pipe 70 in which a water flow channel is formed; A valve assembly 7, the valve assembly 7 includes a valve body 71 and a rotating member 72. The valve body 71 is rotatably disposed in the connecting pipe 70. The rotating member 72 is disposed on the valve body 71 and extends outside the pipe wall of the connecting pipe 70. The valve body 71 is configured to open and close the connecting pipe 70.

[0027] Specifically, the valve body 71 is located in the connecting pipe 70 and can rotate in the connecting pipe 70 to control the opening and closing of the connecting pipe 70 by the rotating valve body 71. The rotating member 72 that drives the rotation of the valve body 71 extends outside the pipe wall of the connecting pipe 70, and then drives the rotation of the rotating member 72 to drive the rotation of the valve body 71 in the connecting pipe 70. In this way, the function of a switching valve can be integrated in the connecting pipe 70.

[0028] By integrating the valve body in the valve assembly into the connecting pipe, the valve body is directly installed inside the connecting pipe and rotates to operate the switch connecting rod, achieving an integrated design of functions. At the same time, to facilitate users to operate the valve assembly externally, the rotating component extends to the outside of the connecting pipe, enabling users to control the rotation of the valve body inside the connecting pipe through the rotating component outside the connecting pipe, completing the function of switching the connecting pipe, realizing the function of integrating a switch valve in the connecting pipe, achieving an integrated design of functions, simplifying the on-site assembly process, and meeting the compact installation requirements of the water heater.

[0029] Among them, for the specific structure of the valve body 71, the structure of the valve body 71 in a conventional valve can be adopted. For example, the valve body 71 can be a valve plate, and the valve plate is rotated to control the opening and closing of the sewage connecting pipe.

[0030] Alternatively, the valve body 71 can be a spherical structure. A water flow hole is arranged perpendicular to the axis of the sphere. The position of the water flow hole is controlled by rotating the sphere to realize the on-off of the sewage connecting pipe. Sealing plugs 77 are respectively arranged on both sides of the sphere in the connecting pipe. The sealing plugs are provided with water flow auxiliary holes. The two sealing plugs are arranged oppositely, and the valve body is clamped between the two sealing plugs. In the state where the valve assembly opens the connecting pipe, the water flow hole communicates with the water flow auxiliary holes on both sides. In the state where the valve assembly opens the connecting pipe, the sphere blocks the water flow auxiliary holes.

[0031] In one embodiment, to facilitate users to open and close the valve body 71 during actual use, the valve assembly 7 further includes a driving handle 73. The driving handle 73 is rotatably arranged on the connecting pipe 70 and is configured to drive the rotating component 72 to rotate.

[0032] Specifically, the driving handle 73 is rotatably installed on the sewage connecting pipe. When a user rotates the driving handle 73 by hand, the rotating component 72 can be driven to drive the valve body 71 to rotate, so as to realize the opening and closing of the connecting pipe 70.

[0033] In some embodiments, to meet the user's requirement of labor-saving operation while achieving a compact design of the structure, a passive gear structure 74 is arranged on the rotating component 72, and an active gear structure 75 is arranged on the driving handle 73. The passive gear structure 74 and the active gear structure 75 are meshed.

[0034] Specifically, for the end of the rotating component 72 extending to the outside of the connecting pipe 70, a passive gear structure 74 is arranged. At the same time, an active gear structure 75 is configured on the driving handle 73. By rotating the driving handle 73, the active gear structure 75 is meshed with the passive gear structure to realize labor-saving driving of the rotation of the rotating component 72.

[0035] In another embodiment, in order to conveniently integrate and assemble the driving handle 73 onto the connecting pipe 70, the valve assembly 7 further includes a connecting member 76. The connecting member 76 is disposed at the pipe orifice of the connecting pipe 70. A sewage discharge hole 761 is provided on the connecting member 76, and the sewage discharge hole 761 communicates with the connecting pipe 70. An installation hole 731 is provided on the driving handle 73, and the connecting member 76 and / or the connecting pipe 70 is inserted into the installation hole 731. The connecting member 76 is configured to prevent the driving handle 73 from detaching from the connecting pipe 70.

[0036] Specifically, the driving handle 73 needs to be integrally installed on the connecting pipe 70 and can rotate on the connecting pipe 70. For this purpose, an installation hole 731 is provided on the driving handle 73. By means of the installation hole 731, the driving handle 73 can rotate relative to the connecting pipe 70. The connecting member 76 is connected to the pipe orifice of the connecting pipe 70 so that the driving handle 73 is located between the connecting member 76 and the passive gear structure 74. On the one hand, it can ensure that the active gear structure 75 can reliably mesh with the passive gear structure 74. On the other hand, the connecting member 76 can ensure that the driving handle 73 is reliably installed on the connecting pipe 70 to meet the requirements of integrated installation.

[0037] Among them, for the driving handle 73, it can be directly sleeved outside the connecting pipe 70 to meet the requirement of rotatable installation. Or, a stepped structure can be provided on the connecting member 76, and the driving handle 73 is rotatably installed on the stepped structure through the installation hole 731 to limit the driving handle 73 by the stepped surface of the stepped structure.

[0038] Embodiment 2, as Figure 1 and Figure 2 shown, the present application provides a water heater, which includes a water heater main body 100. The physical entity of the water heater main body 100 can be the water tank of an electric water heater, or a heat pump water heater, or a solar water heater.

[0039] When the water heater main body 100 is used in a user's home, it is installed on the wall of the user's home according to the installation requirements.

[0040] Among them, the water heater main body 100 is configured with a water inlet pipe 200 and a water outlet pipe 300. In order to improve the water inlet quality of the water heater, a pre-filter 500 can be added between the water inlet pipe 200 of the water heater and the water supply pipe in the user's home to filter the water output from the water supply pipe through the pre-filter 500.

[0041] As Figures 3 - 8As shown, in general, the pre-filter includes an installation main body 1 and a filtering component. The filtering component includes a filter element 2 and a filter bottle 3. The installation main body 1 is used to meet the connection requirements between the water inlet pipe of the water heater and the water supply pipe in the user's home. At the same time, the installation main body 1 is also used to install the filter element 2 and the filter bottle 3 of the filtering component.

[0042] The filter bottle 3 and the filter element 2 are arranged on the installation main body 1. The filter bottle 3 covers the filter element 2. The water inlet connecting pipe 11 is communicated with the inlet, and the water outlet connecting pipe 12 is communicated with the outlet. Among them, a water inlet connecting pipe 11 and a water outlet connecting pipe 12 are arranged on the installation main body 1; the filter element 2 includes a housing 21 and a filter net 24. The housing 21 is provided with an inlet and an outlet, and the filter net 24 covers the inlet.

[0043] In addition, since the filter element 2 is installed between the installation main body 1 and the filter bottle 3, in order to meet the requirement of regularly cleaning the filter net 24 on the filter element 2, the pre-filter further includes a cleaning component 6. The cleaning component 6 is provided with a first water flow driving part 61 and a first cleaning part 62.

[0044] The cleaning component 6 is rotatably sleeved on the housing 21. The first water flow driving part 61 is configured to be driven by water flow to drive the cleaning component 6 to rotate on the housing 21. The first cleaning part 62 is configured to rotate following the cleaning component 6 to scrape the filter net 24 on the housing 21.

[0045] Correspondingly, in order to discharge the sewage formed by cleaning in time after cleaning the filter element 2 through the cleaning component 6, a sewage discharge connecting pipe 17 is further arranged on the installation main body 1. The sewage discharge connecting pipe 17 is communicated with the internal space of the filter bottle 3.

[0046] Specifically, during actual use, when the pre-filter is in normal filtering use, water enters the installation main body 1 through the water inlet connecting pipe 11 and flows into the filter bottle 3. The water is filtered by the filter net on the housing 21 in the filter bottle 3 and flows into the housing 21 through the inlet on the housing 21 and finally outputs from the outlet of the housing 21; the water output from the outlet of the filter element 2 will enter the water outlet connecting pipe 12 and be output and used in the water heater.

[0047] After long-term use, the surface of the filter net will be covered with dirt such as sediment filtered out. In this way, the filtering ability of the filter net will be reduced, and then the filtering efficiency will be decreased. At this time, the sewage discharge connecting pipe 17 can be opened to clean the filter net of the filter element 2 through the cleaning component 6.

[0048] Specifically, first open the sewage connection pipe 17, and the water introduced by the water inlet connection pipe 11 enables the water in the filter bottle 3 to be discharged through the sewage connection pipe 17. During the flow of water in the pre-filter, the water flow acts on the first water flow driving part 61 of the cleaning component 6, causing the first water flow driving part 61 to drive the cleaning component 6 to rotate. In this way, the dirt on the filter screen of the filter element 2 can be scraped by the first cleaning part 62 on the rotating cleaning component 6, so as to clean the dirt on the surface of the filter screen, and then restore the filtering ability of the filter screen, ensuring that the pre-filter can maintain a high filtering efficiency stably for a long time, and thus extending the overall service life of the pre-filter.

[0049] Among them, when the sewage connection pipe 17 is in an open state, the water introduced from the water inlet connection pipe 11 enters the installation main body 1, and at least part of the water flows from the installation main body 1 into the filter bottle 3 and drives the first water flow driving part 61 to drive the cleaning component 6 to rotate on the housing 21 so as to clean the filter screen 24 through the first cleaning part 62, and the water flowing into the filter bottle 3 flows out through the surface of the housing 21 into the sewage connection pipe 17.

[0050] Specifically, during use, when the sewage connection pipe 17 is opened, the water introduced by the water inlet connection pipe 11 will enter the filter bottle 3. In addition, there will also be part of the water flow introduced by the water inlet connection pipe 11 directly discharged from the sewage connection pipe 17 inside the installation main body 1 under the action of the water outlet of the sewage connection pipe 17.

[0051] By configuring the cleaning component 6 on the filter element 2, the cleaning component 6 is provided with a first water flow driving part 61 and a first cleaning part 62. The first water flow driving part 61 can use the water flow flowing in the pre-filter to drive the cleaning component 6 to rotate on the filter element 2. In this way, when it is necessary to clean the surface of the filter element 2 in the pre-filter, open the sewage connection pipe 17, and use the water flow flowing into the pre-filter to drive the cleaning component 6 to rotate to clean the filter screen 24 of the filter element 2, reducing the reduction of the filtering efficiency of the pre-filter caused by the blockage of the filter screen 24 of the filter element 2, and realizing the improvement of the filtering efficiency of the pre-filter and the extension of the service life.

[0052] In one embodiment, in order to ensure that the cleaning component 6 can rotate reliably on the housing 21 of the filter element 2, a first supporting part 63 is provided at one end of the cleaning component 6, and the first supporting part 63 abuts against the outer surface of the housing 21 and is configured to support the cleaning component 6 to rotate on the housing 21.

[0053] Specifically, the cleaning component is supported on the housing 21 through the first support portion 63 to enable the cleaning component to rotate on the housing 21. The first support portion 63 is installed near the side of the installation main body 1, and the first support portion 63 and the first cleaning portion 62 abutting against the filter mesh cooperate to meet the requirement for the cleaning component to rotate on the housing 21.

[0054] In some embodiments, in order to improve the support reliability of the first support portion 63, the first support portion 63 is of a sleeve structure. The first support portion 63 will be sleeved outside the housing 21 to support the rotation of the cleaning component.

[0055] In addition, in order to increase the rotational driving force generated by the cleaning component under the action of water flow, a second water flow driving portion 64 is provided on the outer surface of the first support portion 63, and the first water flow driving portion 61 and the second water flow driving portion 64 are arranged adjacent to each other along the rotation axis direction of the cleaning component 6; wherein, the first water flow driving portion 61 is configured to be driven by the water flow flowing in the direction of the filter bottle 3 to drive the cleaning component 6 to rotate; The second water flow driving portion 64 is configured to be driven by the water flow flowing in the direction of the sewage connection pipe 17 to drive the cleaning component 6 to rotate.

[0056] Specifically, for the water flow flowing inside the pre-filter, it is divided into the water flow that enters the installation main body 1 from the water inlet connection pipe 11 and flows in the direction of the filter bottle 3, and this water flow can act on the first water flow driving portion 61.

[0057] Meanwhile, for the water flow flowing inside the pre-filter, it is also divided into the water flow that flows from the filter bottle 3 to the installation main body 1 and is discharged from the sewage connection pipe 17, and this water flow can act on the second water flow driving portion 64.

[0058] In this way, under the driving action of the water flow on both the first water flow driving portion 61 and the second water flow driving portion 64, the cleaning component will be driven to rotate effectively on the housing 21 to drive the first cleaning portion 62 to effectively clean the filter mesh.

[0059] In some embodiments, the first water flow driving portion 61 and the second water flow driving portion 64 are respectively a plurality of flow guiding rib strips formed in the circumferential direction of the outer periphery of the cleaning component 6.

[0060] Specifically, the water flow in the pre-filter acts on the flow guiding rib strips, and the flow guiding rib strips will generate resistance to the water flow, and use the reaction force of the water flow to drive the cleaning component to rotate.

[0061] Among them, the flow guiding rib strips are arranged obliquely with respect to the rotation axis of the cleaning component 6. The inclined arrangement direction of the flow guiding rib strips is matched with the water flow acting on them, so that the flow guiding rib strips respectively constituting the first water flow driving part 61 and the second water flow driving part 64 can apply the rotational driving force in the same direction to the cleaning component.

[0062] In another embodiment, the other end of the cleaning component 6 is provided with a second supporting part 65, and the second supporting part 65 abuts against the outer surface of the housing 21 and is configured to cooperate with the first supporting part 63 to support the cleaning component 6 to rotate on the housing 21.

[0063] Specifically, the other end of the cleaning component 6 is further configured with a second supporting part 65, and the first supporting part 63 and the second supporting part 65 cooperate with each other so that the cleaning component 6 is effectively installed on the housing 21.

[0064] Among them, there can be multiple forms of the specific structural manifestation of the second supporting part 65. For example: the second supporting part 65 can also adopt a sleeve structure to be sleeved on the housing 21, or the second supporting part 65 is multiple supporting columns 503 to abut against the housing 21.

[0065] In another embodiment, the cleaning component 6 is integrally in a sleeve structure, and the first cleaning part 62 is arranged on the inner wall of the cleaning component 6.

[0066] Specifically, in order to enable the cleaning component 6 to thoroughly clean the housing 21, the cleaning component 6 is in a sleeve structure to be sleeved on the outside of the housing 21, and a plurality of first cleaning parts 62 can be arranged on the inner wall of the cleaning component 6.

[0067] In addition, a second cleaning part 66 can also be arranged on the outer wall of the cleaning component 6, and the second cleaning part 66 abuts against the inner wall of the filter bottle 3. So as to clean the inside of the filter bottle 3 through the second cleaning part 66.

[0068] The first cleaning part 62 and the second cleaning part 66 are in a strip structure and extend along the rotation axis direction of the cleaning component 6, and the first cleaning part 62 and the second cleaning part 66 can be made of flexible materials such as silica gel or rubber, so that the first cleaning part 62 and the second cleaning part 66 can closely adhere to the surface to be cleaned.

[0069] The surface of the cleaning component 6 is provided with a hollow structure to allow the water in the filter bottle 3 to enter the inside of the cleaning component 6 through the hollow structure for filtration treatment by the filter element 2.

[0070] In another embodiment of the present application, for the sewage connection pipe 17, an independent valve assembly 7 can be externally connected to control the opening and closing of the controller, or a valve assembly 7 can be integrally provided on the sewage connection pipe 17.

[0071] In another embodiment of the present application, a decorative cover 400 is further provided on the water heater main body 100, and the water inlet pipe 200 and the water outlet pipe 300 are arranged on the back of the decorative cover 400. It is characterized in that a pre-filter 500 is further included; For the pre-filter 500, the filtering assembly is horizontally arranged as a whole and hidden on the back of the decorative cover 400.

[0072] Specifically, the water inlet pipe 200 configured in the water heater is used to supply water inside, and the water outlet pipe 300 is used to output the heated water to the water-using terminal. For the water entering the water inlet pipe 200, the water quality can be filtered by the pre-filter 500 first to improve the quality of the water entering the water heater.

[0073] Among them, since the pre-filter 500 is installed on the water inlet pipe 200, in order to enable the pre-filter 500 to be installed in a hidden manner, the installation structure of the pre-filter 500 is improved and designed.

[0074] Specifically, the filter element 2 and the filter bottle 3 of the pre-filter 500 are both arranged horizontally and are installed and arranged by horizontally extending the space at the bottom of the water heater. In this way, the overall height dimension of the pre-filter 500 can be effectively reduced, and the installation requirements of the pre-filter 500 can be met by using the horizontal space at the bottom of the water heater.

[0075] The installation main body 1 of the pre-filter 500 is connected to the external water pipe through the water inlet connection pipe 11 and is connected to the water inlet pipe 200 on the water heater main body 100 through the water outlet connection pipe 12. The filter element 2 and the filter bottle 3 are installed on the corresponding connection ports of the installation main body 1.

[0076] As Figures 3 - 10 shown, in the filter provided in another embodiment of the present application, in order to facilitate the connection of different water circuits in the installation main body 1, based on the above-mentioned first embodiment, a water distributor 5 is further provided, and the water distributor 5 is used to meet the water circuit connection requirements between the water inlet connection pipe 11, the water outlet connection pipe 12, the sewage connection pipe 17 and the filter element 2.

[0077] Specifically: the installation main body 1 is provided with an open installation cavity, a first connection port 13 is provided at the open end of the installation cavity, and a second connection port 14 is further provided inside the installation cavity at the first connection port 13.

[0078] A first water flow interface 55, a second water flow interface 57 and a third water flow interface 56 are provided on the water distributor 5.

[0079] Among them, the water distributor 5 is arranged on the second connection port 14, the filter bottle 3 is arranged on the first connection port 13 and is hermetically connected to the water distributor 5. An outlet water cavity is formed between the water distributor 5 and the inner wall of the installation main body 1, and an inlet water cavity is formed between the water distributor 5 and the filter bottle 3; the filter element 2 and the cleaning component 6 are arranged between the water distributor 5 and the filter bottle 3, and the cleaning component 6 is rotatably sleeved on the housing 21; The inlet connection pipe 11 is communicated with the inlet through the first water flow interface 55, the outlet connection pipe 12 is communicated with the outlet through the second water flow interface 57, and the sewage connection pipe 17 is communicated with the inner space of the filter bottle 3 through the third water flow interface 56.

[0080] Specifically, a water distributor 5 is built into the installation main body 1. The water distributor 5 forms an independent outlet water cavity in the installation main body 1 to be directly connected to the outlet connection pipe 12, while an inlet water cavity is formed between the water distributor 5 and the outer filter bottle 3 in the installation main body 1 to meet the connection requirements of the inlet connection pipe 11.

[0081] Correspondingly, a first water flow interface 55, a second water flow interface 57 and a third water flow interface 56 are provided on the water distributor 5 to meet the water connection requirements of the inlet connection pipe 11, the outlet connection pipe 12 and the sewage connection pipe 17 configured on the installation main body 1.

[0082] During use, the water flow flowing into the inner side of the water distributor 5 through the first water flow interface 55 will act on the first water flow driving part 61, so that the first water flow driving part 61 drives the cleaning component 6 to rotate on the housing 21 under the drive of the water flow. Furthermore, the first cleaning part 62 is driven to rotate along with the cleaning component 6 to scrape the filter net 24 on the housing 21.

[0083] In some embodiments, for the water distributor 5, it has an end plate part 501 and an annular part 502. The first water flow interface 55 and the third water flow interface 56 are arranged on the annular part 502, and the second water flow interface 57 is arranged on the end plate part 501.

[0084] Specifically, the water distributor 5 has a cover shell structure. The end plate part 501 of the water distributor 5 is used to form an outlet water cavity at intervals inside the installation cavity of the installation main body 1, and the outlet water cavity can be connected to the inlet of the filter element 2 through the second water flow interface 57.

[0085] The annular portion 502 of the water separator 5 is provided with a first water flow interface 55 and the third water flow interface 56 to connect the water inlet connecting pipe 11 and the sewage connecting pipe 17 respectively.

[0086] Among them, after the water separator 5 is arranged in the installation main body 1, the end of the filter element 2 with an inlet is connected to the second water flow interface 57 and is surrounded by the annular portion 502. Moreover, a connection and matching structure for sealed connection is formed between the annular portion 502, the filter bottle 3 and the installation main body 1, so that a water inlet cavity is formed between the water separator 5 and the filter bottle 3. In this way, the water conveyed by the water inlet connecting pipe 11 enters the water inlet cavity, and the water in the water inlet cavity is filtered through the filter screen 24 of the filter element 2 and output from the outlet of the filter element 2. The water output from the filter element 2 flows into the water outlet cavity through the second water flow interface 57 and is finally output from the water outlet connecting pipe 12.

[0087] In some embodiments, a plurality of support columns 503 are arranged on the end plate portion 501. The support columns 503 are located in the water outlet cavity and abut against the installation main body 1.

[0088] Specifically, in order to position the installation position of the water separator 5, a plurality of support columns 503 can be arranged on the end plate portion 501. After the water separator 5 is assembled into the installation cavity of the installation main body 1, the support columns 503 abut against the inner wall of the installation cavity to form a water outlet cavity at intervals between the water separator 5 and the installation main body 1. Among them, the plurality of support columns 503 are distributed around the second water flow interface 57.

[0089] In some embodiments, a diversion channel 551 is further arranged on the inner wall of the annular portion 502. The diversion channel 551 communicates with the first water flow interface 55, and the water outlet holes of the diversion channel 551 face the first water flow driving portion 61.

[0090] Specifically, in order to effectively drive the cleaning component 6 to rotate rapidly on the filter element 2, the water flowing into the water inlet cavity needs to effectively impact the first water flow driving portion 61 on the cleaning component 6. For this reason, a diversion channel 551 is arranged on the inner wall of the annular portion 502 to guide the water flowing in from the first water flow interface 55. The water outlet holes of the diversion channel 551 discharge water in the direction of the first water flow driving portion 61, and the water output from the water outlet holes of the diversion channel 551 will act on the first water flow driving portion 61, thereby ensuring that the first water flow driving portion 61 bears a sufficient large water pressure to drive the cleaning component 6 to rotate.

[0091] Similarly, one end portion of the cleaning component 6 is provided with a first support portion 63. The first support portion 63 abuts against the outer surface of the housing 21 and is configured to support the cleaning component 6 to rotate on the housing 21. The annular portion 502 is located outside the first support portion 63.

[0092] The first support portion 63 is of a sleeve structure, and a second water flow driving portion 64 is provided on the outer surface of the first support portion 63. The first water flow driving portion 61 and the second water flow driving portion 64 are arranged adjacent to each other along the rotation axis direction of the cleaning component 6. Wherein, the first water flow driving portion 61 is configured to be driven by the water flow flowing towards the filter bottle 3 to drive the cleaning component 6 to rotate. The second water flow driving portion 64 is configured to be driven by the water flow flowing towards the sewage connection pipe 17 to drive the cleaning component 6 to rotate.

[0093] Specifically, for the first support portion 63, it is located in the space formed by the surrounding of the annular portion 502, and a third water flow interface 56 is further provided on the annular portion 502. In this way, the water flow flowing out from the third water flow interface 56 can be further utilized to act on the second water flow driving portion 64 to increase the rotation speed of the water flow driving the cleaning component 6.

[0094] In another embodiment, in order to reduce the mutual influence between the water flows received by the first water flow driving portion 61 and the second water flow driving portion 64, the cleaning component 6 is integrally of a sleeve structure, and the first cleaning portion 62 is arranged on the inner wall of the cleaning component 6; a plurality of connecting ribs 67 are provided between the first support portion 63 and the cleaning component 6, and a water flow interval is formed between two adjacent connecting ribs 67. The water flow interval is configured to output water flow towards the second water flow driving portion 64.

[0095] Specifically, for the diversion channel 551, the water outlet direction of the diversion channel 551 is towards the water outlet of the filter bottle 3 to generate a water flow impact on the first water flow driving portion 61 in its water outlet direction. The water flowing into the filter bottle 3 can flow into the space between the cleaning component 6 and the filter element 2 and then flow back to the third water flow interface 56 of the water distributor 5. During the process of the water flow flowing back to the water distributor 5, it can flow out through the water flow interval between the two connecting ribs 67 to avoid the first water flow driving portion 61 on the outer wall of the cleaning component 6; and the water flow flowing out from the water flow interval flows onto the surface of the first support portion 63 to generate a water flow impact on the second water flow driving portion 64, thereby better meeting the requirement of using the water flow to drive the cleaning component 6 to rotate.

[0096] In some embodiments, a second cleaning portion 66 is further provided on the outer wall of the cleaning member 6, and the second cleaning portion 66 abuts against the inner wall of the filter bottle 3. The first cleaning portion 62 and the second cleaning portion 66 are in a strip structure and extend along the rotation axis direction of the cleaning member 6. The surface of the cleaning member 6 is provided with a hollow structure. Moreover, in order to ensure reliable support for both ends of the cleaning member 6, a second support portion 65 may be provided at the other end of the cleaning member 6, and the second support portion 65 abuts against the outer surface of the housing 21 and is configured to cooperate with the first support portion 63 to support the rotation of the cleaning member 6 on the housing 21. For specific details, reference may be made to the description in the first embodiment above, and details will not be elaborated here.

[0097] In some embodiments, to enable the user to intuitively see the usage state of the filter element 2 in the filter bottle 3 and replace the filter element 2 in a timely manner when the water quality is poor, the filter bottle 3 is made of a transparent or semi-transparent structure.

[0098] Specifically, since the filter bottle 3 is made of a transparent or semi-transparent material, when the user is using it, the state of the filter element 2 in the filter bottle 3 can be directly observed, and thus, when the water quality condition is poor, the replacement cycle of the filter element 2 can be shortened.

[0099] Embodiment 3, in another embodiment of the present application, for the installation main body, it can be an integral structure. For the convenience of processing, the installation main body can also adopt a split structure, which will be described below with reference to the accompanying drawings.

[0100] As Figure 7 shown, that is, the installation main body 1 includes a first installation component 15 and a second installation component 16. The first installation component 15 is provided with the water inlet connecting pipe 11 and the water outlet connecting pipe 12. An installation cavity is formed in the second installation component 16. The second installation component 16 is provided with a first connection port 13, a second connection port 14, and a sewage connecting pipe 17. The first installation component 15 and the second installation component 16 are fixedly connected together. The water inlet connecting pipe 11, the water outlet connecting pipe 12, and the sewage connecting pipe 17 are respectively communicated with the installation cavity. The inlet of the filter element 2 is located in the filter bottle 3, and the outlet of the filter element 2 is located in the installation cavity.

[0101] Specifically, for the installation main body 1, since two independent water flow requirements of water inlet and water outlet need to be satisfied inside it, in order to simplify the processing difficulty, the water inlet connecting pipe 11 and the water outlet connecting pipe 12 are provided on the first installation component 15, and the sewage connecting pipe 17 is provided on the second installation component 16.

[0102] In order to meet the requirements of water inlet and outlet inside the installation main body 1 and satisfy the installation design requirements of structural compactness and miniaturization, the following structural improvements are made to the installation main body 1.

[0103] The first installation component 15 is a three-way pipe, and the three ends of the three-way pipe respectively form the water inlet connecting pipe 11, the water outlet connecting pipe 12, and the auxiliary connecting pipe 153. The water inlet connecting pipe 11 and the auxiliary connecting pipe 153 are arranged in opposite directions; A communication port 163 is provided on the second installation component 16, and the communication port 163 communicates with the installation cavity.

[0104] The pre-filter further includes an intermediate pipe 4. The intermediate pipe 4 is arranged in the water inlet connecting pipe 11. The outer end of the intermediate pipe 4 is hermetically connected to the inner pipe wall of the water inlet connecting pipe 11. The water inlet of the water inlet connecting pipe 11 communicates with the intermediate pipe 4. The inner end of the intermediate pipe 4 passes through the communication port 163 and extends into the installation cavity; an auxiliary flow channel 111 is formed between the outer pipe wall of the intermediate pipe 4 and the inner pipe wall of the water inlet connecting pipe 11. The water outlet connecting pipe 12 communicates with the water outlet cavity through the auxiliary flow channel 111 and the communication port 163, and the inner pipe orifice of the intermediate pipe 4 communicates with the water inlet cavity.

[0105] Specifically, for the first installation component 15, its overall structure is a three-way pipe structure, and correspondingly, the water inlet connecting pipe 11 and the water outlet connecting pipe 12 are formed. The other pipe orifice of the three-way pipe will form the auxiliary connecting pipe 153 to be connected to the communication port 163 of the second installation component 16 through the auxiliary connecting pipe 153.

[0106] For the water inlet connecting pipe 11 and the water outlet connecting pipe 12 on the first installation component 15, they need to meet the requirements of water inlet and outlet. By arranging the intermediate pipe 4 in the water inlet connecting pipe 11, an auxiliary flow channel 111 can be formed between the intermediate pipe 4 and the inner pipe wall of the water inlet connecting pipe 11. The first installation component 15 has a three-way pipe structure, so that the auxiliary flow channel 111 communicates with the water outlet connecting pipe 12. After the first installation component 15 is connected to the second installation component 16, the auxiliary connecting pipe 153 is connected to the communication port 163, so that the auxiliary flow channel 111 communicates with the water outlet cavity through the communication port 163. At the same time, the pipe orifice at the inner end of the intermediate pipe 4 extends into the installation cavity of the second installation component 16 through the auxiliary connecting pipe 153 and the communication port 163 to communicate with the water inlet cavity.

[0107] The auxiliary flow channel 111 is formed in the water inlet connecting pipe 11 by using the intermediate pipe 4 to meet the connection requirement between the water outlet connecting pipe 12 and the water outlet cavity, making the overall structure of the first installation component 15 more compact and small, and further meeting the design requirements of miniaturization.

[0108] The water distributor 5 disposed in the installation cavity of the second installation component 16 is used to separate the water outlet cavity and the water inlet cavity in the installation cavity of the second installation component 16. A protruding annular spacer 51 is provided on the annular portion on one side of the communication port 163, so that the water inlet cavity and the water outlet cavity are separated in the installation cavity of the second installation component 16.

[0109] In some embodiments, a plug-in portion 54 is provided on the annular portion. A first water flow interface 55 arranged opposite to the communication port 163 is provided on the plug-in portion 54, and the first water flow interface 55 communicates with a diversion channel 551 on the inner wall of the annular portion; The inner end portion of the intermediate pipe 4 is hermetically inserted into the first water flow interface 55, and the inner pipe orifice of the intermediate pipe 4 communicates with the water inlet cavity through the diversion channel 551.

[0110] During the assembly process, the inner end portion of the intermediate pipe 4 is inserted into the first water flow interface 55, so that the intermediate pipe 4 communicates with the water inlet cavity through the diversion channel 551. Moreover, the intermediate pipe 4 and the plug-in portion 54 cooperate with each other so that the inner port of the intermediate pipe 4 can be isolated from the water outlet cavity, thus meeting the effective isolation between the water inlet cavity and the water outlet cavity.

[0111] In addition, by configuring the plug-in portion 54 on the annular portion, it can better meet the flow requirements of the water outlet flow by borrowing the internal flow channel of the water inlet connecting pipe 11 for the water outlet connecting pipe 12. At the same time, during the overall assembly of the pre-filter, it is convenient to effectively connect the inner end portion of the intermediate pipe 4 to the water inlet cavity while also meeting the effective isolation from the water outlet cavity, facilitating the quick and precise assembly of the pre-filter.

[0112] In order to further increase the space at the water inlet orifice of the water outlet connecting pipe 12, a recessed structure 41 can also be provided on the intermediate pipe 4. The recessed structure 41 is arranged opposite to the water inlet orifice of the water outlet connecting pipe 12. In this way, the water received and sent by the auxiliary flow channel 111 can flow more smoothly into the water outlet connecting pipe 12 at the recessed structure 41 to ensure the smooth flow of the water outlet flow.

[0113] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
