[0050] Thermostatic valve 600, the thermostatic valve 600 having a first water inlet 610, a second water inlet 620 and a total water outlet 630;

[0051] Filter 500, the filter 500 having a first pair of interfaces 40 and a second pair of interfaces 10, the filter 500 being configured to filter water flowing in through the first pair of interfaces 40 and then output the filtered water from the second pair of interfaces 10;

[0052] Connection pipe group 700, the connection pipe group 700 including a multi-way pipe 710 and a diversion pipe 720, the multi-way pipe 710 having a total water inlet 711, a second water outlet 712, a third water outlet 713 and a mounting port 714, the diversion pipe 720 being inserted into the multi-way pipe 710 and sealingly communicating with the total water inlet 711, a water flow channel being formed between the inner wall of the diversion pipe 720 and the multi-way pipe 710, and the second water outlet 712 and the third water outlet 713 being respectively communicated with the water flow channel;

[0053] Wherein, the second pair of interfaces 10 is connected to the mounting port 714, the diversion pipe 720 is sealingly connected to the first pair of interfaces 40, the water flow channel is communicated with the second pair of interfaces 10, and the second water outlet 712 is connected to the second water inlet 620.

[0054] Specifically, the connection pipe group 700 is used to connect the filter 500 and the thermostatic valve 600 together, that is, the second water outlet 712 of the multi-way pipe 710 can be connected to the second water inlet 620 of the thermostatic valve 600 through a bypass pipe 800 to complete the assembly of the filtration and thermostatic module; and the filtration and thermostatic module is connected to the water outlet pipe of the water heater through the first water inlet 610 of the thermostatic valve 600 and is connected to the water inlet pipe of the water heater through the third water outlet 713 of the connection pipe group 700.

[0055] Wherein, for the filter 500, it is fixedly installed on the mounting port 714 of the multi-way pipe 710, and the first pair of interfaces 40 is communicated with the total water inlet 711 through the diversion pipe 720 so that tap water flows into the filter 500, and then, the second pair of interfaces 10 is communicated with the mounting port 714 to be communicated with the water flow channel outside the diversion pipe 720. In this way, the water filtered by the filter 500 is output through the second pair of interfaces 10 and flows into the water flow channel, and then the filtered water is respectively output from the second water outlet 712 and the third water outlet 713 according to needs through the water flow channel.

[0056] Since the diversion pipe 720 is inserted into the multi-way pipe 710 to simultaneously meet the requirements for the water inlet and outlet of the filter 500, thereby achieving a compact design. At the same time, for the multi-way pipe 710, it can also meet the connection requirements with the thermostatic valve 600, the water supply pipe, and the water heater. The connection pipe group 700 has a compact structure, which is more conducive to reducing the overall volume of the filtering and thermostatic module to reduce the space occupation.

[0057] In one embodiment, the multi-way pipe 710 has a first pipe body 715, a second pipe body 716, a third pipe body 717, and a fourth pipe body 718; a total water inlet 711 is provided on the first pipe body 715, a second water outlet 712 is provided on the second pipe body 716, a third water outlet 713 is provided on the third pipe body 717, and a mounting port 714 is provided on the fourth pipe body 718; wherein, the fourth pipe body 718 and the first pipe body 715 are arranged oppositely, the third pipe body 717 is provided on the pipe wall of the fourth pipe body 718, and the second pipe body 716 is connected between the first pipe body 715 and the fourth pipe body 718.

[0058] Specifically, for the multi-way pipe 710, it has multiple pipe bodies by which the total water inlet 711, the second water outlet 712, the third water outlet 713, and the mounting port 714 are correspondingly formed, and at the same time, the requirements for connection and installation are met.

[0059] Wherein, a baffle 719 is further provided in the first pipe body 715, and the baffle 719 extends from the first pipe body 715 into the fourth pipe body 718; the baffle 719 is provided with an outward-turned edge structure 7191, the outward-turned edge structure 7191 is connected to the inner wall of the fourth pipe body 718, a water passing hole 7192 is further provided on the outward-turned edge structure 7191, and a jack is formed between the inner surface of the baffle 719 and the inner wall of the fourth pipe body 718, and the jack communicates with the total water inlet 711;

[0060] The baffle 719 is blocked inside the second pipe body 716 and is configured to separate the second water outlet 712 from the total water inlet 711;

[0061] Wherein, one end of the diversion pipe 720 is hermetically inserted into the jack, and the other end of the diversion pipe 720 is hermetically inserted into the first pair of interfaces 40.

[0062] Specifically, for the total water inlet 711, the water introduced needs to be input into the filter 500 via the diversion pipe 720, and then, the filtered water flows back into the water flow channel after output from the filter 500. The baffle 719 can isolate the second water outlet 712 from the first pipe body 715, so that the total water inlet 711 and the second water outlet 712 are not directly connected after the diversion pipe 720 is installed and connected to the filter 500.

[0063] In addition, for the water flowing into the water flow channel, since the outward turning edge structure 7191 is located in the water flow channel, the second water outlet 712 is communicated with the water flow channel through the water passing hole 7192, so as to satisfy that the water in the water flow channel flows into the second pipe body 716 through the water passing hole 7192 and is output from the second water outlet 712.

[0064] In one embodiment, the axis of the fourth pipe body 718 is offset relative to the axis of the first pipe body 715, which is the deflection structure of the diversion pipe 720.

[0065] Specifically, for the multi-way pipe 710, the first pipe body 715 and the fourth pipe body 718 are arranged relatively offset, so that the first pipe body 715 can form a baffle 719 to shield the second pipe body 716.

[0066] Wherein, the diversion pipe 720 includes a first straight pipe section 721, a second straight pipe section 722 and an inclined pipe section 723, and the inclined pipe section 723 is connected between the first straight pipe section 721 and the second straight pipe section 722;

[0067] Wherein, the end of the first straight pipe section 721 is inserted into the jack, and the end of the second straight pipe section 722 extends outside the mounting port 714 and is inserted into the first mating port 40.

[0068] Specifically, the two straight pipe sections of the diversion pipe 720 can better meet the requirements of sealing plug connection with the jack and the first mating port 40, and the inclined pipe section 723 can meet the installation requirements of the relative offset arrangement of the first pipe body 715 and the fourth pipe body 718.

[0069] In addition, a plurality of first support ribs 724 are arranged on the outer periphery of the second straight pipe section 722, and the first support ribs 724 abut against the inner wall of the fourth pipe body 718. And / or, a plurality of second support ribs 725 are arranged on the outer periphery of the inclined pipe section 723, and the second support ribs 725 abut against the inner wall of the fourth pipe body 718.

[0070] In another embodiment, the multi-way pipe 710 has a fifth pipe body 7101, a pressure relief valve 730 is arranged on the fifth pipe body 7101, and the fifth pipe body 7101 communicates with the first pipe body 715.

[0071] Specifically, the setting of the pressure relief valve 730 can meet the normal pressure relief requirement of the water heater.

[0072] Embodiment 2: Based on the above embodiment 1, the filter can adopt a conventional filter structure. Similarly, in order to realize automatic cleaning of the filter element, the filter can also be improved as follows. Figures 6 - 8 As shown, the filter in this embodiment includes a connecting body 1 and a filter assembly, and the filter assembly includes a filter element 2, a filter bottle 3 and an intermediate tube 4.

[0073] The connection body 1 forms an installation cavity, and the connection body 1 is also provided with a sewage connection pipe 12 and an installation pipe 11, which are respectively connected to the installation cavity. The outer port of the installation pipe 11 forms a second docking port 10, and the installation pipe 11 is connected to the installation cavity through the connecting port.

[0074] The connecting 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 connecting body 1 is also used to install the filter element 2 and the filter bottle 3 of the filter assembly.

[0075] The filter bottle 3 and the filter element 2 are arranged on the connecting body 1, the filter bottle 3 covers the filter element 2, the intermediate tube 4 is connected with the inlet, the installation tube 11 is connected with the outlet, the filter element 2 includes a shell 21 and a filter screen 24, the shell 21 is provided with an inlet and an outlet, and the filter screen 24 covers the inlet.

[0076] The middle tube 4 is inserted into the mounting tube 11, and the outer port of the middle tube 4 forms a first docking port 40. The tap water flows into the middle tube 4 through the guide tube 720 and flows into the filter element 2 for filtration. The filtered water is transported to the water outlet channel formed between the middle tube 4 and the mounting tube 11, and finally transported from the second docking port 10 to the multi-way tube 710. The middle tube 4 is also provided with a spacing rib 42 to form a water outlet channel between the middle tube 4 and the mounting tube 11.

[0077] In addition, since the filter element 2 is installed between the connecting body 1 and the filter bottle 3, in order to regularly clean the filter mesh 24 on the filter element 2, the filter also includes a cleaning component 6, and the cleaning component 6 is provided with a first water flow driving part 61 and a first cleaning part 62.

[0078] The cleaning component 6 is rotatably mounted on the shell 21 , the first water flow driving portion 61 is configured to be driven by water flow to drive the cleaning component 6 to rotate on the shell 21 , and the first cleaning portion 62 is configured to rotate with the cleaning component 6 to scrape the filter 24 on the shell 21 .

[0079] Correspondingly, in order to timely discharge the sewage formed by cleaning after the filter element 2 is cleaned by the cleaning component 6, a sewage discharge connecting pipe 12 is further provided on the connecting main body 1, and the sewage discharge connecting pipe 12 is communicated with the internal space of the filter bottle 3.

[0080] Specifically, during actual use, when the filter is in normal filtering use, water enters the connecting main body 1 through the intermediate pipe 4 and flows into the filter bottle 3. The water is filtered by the filter screen 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 installation pipe 11 and output to the water heater for use.

[0081] After long-term use, the surface of the filter screen will be covered with dirt such as sediment filtered out. In this way, the filtering ability of the filter screen will be reduced, and then the filtering efficiency will be reduced. At this time, the sewage discharge connecting pipe 12 can be opened to clean the filter screen of the filter element 2 through the cleaning component 6.

[0082] Specifically, first open the sewage discharge connecting pipe 12, and the water introduced by the intermediate pipe 4 enables the water in the filter bottle 3 to be discharged through the sewage discharge connecting pipe 12. During the flow of the water flow in the filter, the water flow acts on the first water flow driving part 61 of the cleaning component 6, so that the first water flow driving part 61 drives the cleaning component 6 to rotate. In this way, the dirt on the surface of the filter screen 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, so as to ensure that the filter can maintain a high filtering ability stably for a long time, and then extend the overall service life of the filter.

[0083] Among them, when the sewage discharge connecting pipe 12 is in an open state, the water introduced from the intermediate pipe 4 enters the connecting main body 1, and at least part of the water flows from the connecting 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 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 discharge connecting pipe 12.

[0084] Specifically, during use, when the sewage discharge connecting pipe 12 is opened, the water introduced by the intermediate pipe 4 will enter the filter bottle 3. In addition, there will also be part of the water flow introduced by the intermediate pipe 4 directly discharged from the sewage discharge connecting pipe 12 inside the connecting main body 1 under the action of the water discharged from the sewage discharge connecting pipe 12.

[0085] By arranging a 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 drive the cleaning component 6 to rotate on the filter element 2 by using the water flow flowing in the filter. In this way, when it is necessary to clean the surface of the filter element 2 in the filter, the sewage connection pipe 12 is opened, and the water flow flowing into the filter is used 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 filter caused by the blockage of the filter screen 24 of the filter element 2, and achieving the improvement of the filtering efficiency of the filter and the extension of the service life.

[0086] 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 support part 63 is arranged at one end of the cleaning component 6, and the first support 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.

[0087] Specifically, the cleaning component is supported on the housing 21 through the first support part 63 to meet the requirement that the cleaning component can rotate on the housing 21. The first support part 63 is installed close to the side of the connection body 1, and the first support part 63 and the first cleaning part 62 abutting against the filter screen cooperate to meet the requirement that the cleaning component rotates on the housing 21.

[0088] In some embodiments, in order to improve the support reliability of the first support part 63, the first support part 63 is of a sleeve structure. The first support part 63 will be sleeved outside the housing 21 to support the rotation of the cleaning component.

[0089] In addition, in order to improve the rotational driving force generated by the cleaning component under the action of the water flow, a second water flow driving part 64 is arranged on the outer surface of the first support part 63, and the first water flow driving part 61 and the second water flow driving part 64 are arranged adjacent to each other along the rotation axis direction of the cleaning component 6;

[0090] Among them, the first water flow driving part 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;

[0091] The second water flow driving part 64 is configured to be driven by the water flow flowing in the direction of the sewage connection pipe 12 to drive the cleaning component 6 to rotate.

[0092] Specifically, for the water flow flowing inside the filter, it is divided into the water flow that enters the connection body 1 from the middle pipe 4 and flows in the direction of the filter bottle 3, and this water flow can act on the first water flow driving part 61.

[0093] Meanwhile, for the water flow inside the filter, it is further divided into the water flow that flows from the filter bottle 3 to the connection body 1 and is discharged from the sewage connection pipe 12, and this water flow can act on the second water flow driving part 64.

[0094] In this way, under the driving action of the water flow, both the first water flow driving part 61 and the second water flow driving part 64 will drive the cleaning component to rotate effectively on the housing 21, so as to drive the first cleaning part 62 to effectively clean the filter screen.

[0095] In some embodiments, the first water flow driving part 61 and the second water flow driving part 64 are respectively a plurality of flow guiding rib strips formed in the circumferential direction of the outer periphery of the cleaning component 6.

[0096] Specifically, the water flow in the 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.

[0097] 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 same-direction rotational driving force to the cleaning component.

[0098] In another embodiment, a second support part 65 is provided at the other end of the cleaning component 6, and the second support part 65 abuts against the outer surface of the housing 21 and is configured to cooperate with the first support part 63 to support the cleaning component 6 to rotate on the housing 21.

[0099] Specifically, the other end of the cleaning component 6 is further configured with a second support part 65, and the first support part 63 and the second support part 65 cooperate with each other to effectively mount the cleaning component 6 on the housing 21.

[0100] Among them, for the specific structural form of the second support part 65, there can be multiple ways. For example: the second support part 65 can also adopt a sleeve structure to sleeved on the housing 21, or the second support part 65 is a plurality of support columns 503 to abut against the housing 21.

[0101] 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.

[0102] 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 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.

[0103] In addition, a second cleaning part 66 can also be arranged on the outer wall of the cleaning part 6, and the second cleaning part 66 is abutted 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.

[0104] 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 part 6. Moreover, 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 be closely attached to the surface to be cleaned.

[0105] The surface of the cleaning part 6 is provided with a hollow structure, so that the water in the filter bottle 3 can enter the inside of the cleaning part 6 through the hollow structure and be filtered by the filter element 2.

[0106] In another embodiment of the present application, for the sewage discharge connecting pipe 12, an independent valve assembly 7 can be externally connected to control the opening and closing of the controller, or a valve assembly 7 can also be integrally arranged on the sewage discharge connecting pipe 12.

[0107] Specifically, the valve assembly 7 includes a valve body 71 and a rotating part 72. The valve body 71 is rotatably arranged in the sewage discharge connecting pipe 12, the rotating part 72 is arranged on the valve body 71, and the rotating part 72 extends out of the pipe wall of the sewage discharge connecting pipe 12; the valve body 71 is configured to open and close the sewage discharge connecting pipe 12.

[0108] Specifically, the valve body 71 is located in the sewage discharge connecting pipe 12 and can rotate in the sewage discharge connecting pipe 12. The opening and closing of the sewage discharge connecting pipe 12 is controlled by the rotating valve body 71. The rotating part 72 for driving the valve body 71 to rotate extends outside the pipe wall of the sewage discharge connecting pipe 12, and then the valve body 71 in the sewage discharge connecting pipe 12 is driven to rotate by driving the rotating part 72 to rotate.

[0109] 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 spherical structure, and a water flow hole is arranged on the sphere perpendicular to its axis. The position of the water flow hole is controlled by rotating the sphere to realize the opening and closing of the sewage discharge connecting pipe; or the valve body 71 can be a valve plate, and the opening and closing of the sewage discharge connecting pipe is controlled by rotating the valve plate.

[0110] In one embodiment, in order to facilitate the user 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 sewage discharge connecting pipe 12 and is configured to drive the rotating part 72 to rotate.

[0111] Specifically, the driving handle 73 is rotatably mounted on the sewage discharge connecting pipe. When the user rotates the driving handle 73 by hand, the rotating member 72 can be controlled to drive the valve body 71 to rotate, so as to open and close the sewage discharge connecting pipe 12.

[0112] In some embodiments, in order to meet the user's labor-saving operation and achieve a compact design of the structure, a passive gear structure 74 is provided on the rotating member 72, an active gear structure 75 is provided on the driving handle 73, and the passive gear structure 74 meshes with the active gear structure 75.

[0113] Specifically, a passive gear structure 74 is provided at the end of the rotating member 72 extending outside the sewage discharge connecting pipe 12. 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 meshes with the passive gear structure to achieve labor-saving driving of the rotating member 72 to rotate.

[0114] In another embodiment, in order to conveniently integrate and assemble the driving handle 73 onto the sewage discharge connecting pipe 12, the valve assembly 7 further includes a connecting member 76. The connecting member 76 is disposed at the pipe orifice of the sewage discharge connecting pipe 12. A sewage discharge hole 761 is provided on the connecting member 76, and the sewage discharge hole 761 communicates with the sewage discharge connecting pipe 12; an installation hole 731 is provided on the driving handle 73, and the connecting member 76 and / or the sewage discharge connecting pipe 12 is inserted into the installation hole 731; the connecting member 76 is configured to prevent the driving handle 73 from falling off the sewage discharge connecting pipe 12.

[0115] Specifically, the driving handle 73 needs to be integrally installed on the sewage discharge connecting pipe 12 and can rotate on the sewage discharge connecting pipe 12. 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 sewage discharge connecting pipe 12, and the connecting member 76 is connected to the pipe orifice of the sewage discharge connecting pipe 12 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 sewage discharge connecting pipe 12 to meet the requirements of integrated installation.

[0116] Among them, for the driving handle 73, it can be directly sleeved outside the sewage discharge connecting pipe 12 to meet the requirement of rotatable installation. Or, a step structure can be provided on the connecting member 76, and the driving handle 73 is rotatably installed on the step structure through the installation hole 731 to limit the driving handle 73 by the step surface of the step structure.

[0117] In another embodiment of the present application, a decorative cover 400 is further provided on the water heater main body 100. The water inlet pipe 200 and the water outlet pipe 300 are arranged on the back of the decorative cover 400, and a filter 500 is further included.

[0118] For the filter 500, the overall filtering component is arranged horizontally and hidden on the back of the decorative cover 400.

[0119] Specifically, the water inlet pipe 200 configured in the water heater is used to meet the internal water inlet, 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 filter 500 first to improve the quality of the water entering the interior of the water heater.

[0120] Among them, since the filter 500 is installed on the water inlet pipe 200, in order to enable the filter 500 to be installed in a hidden manner, the installation structure of the filter 500 is improved and designed.

[0121] Specifically, the filter element 2 and the filter bottle 3 of the filter 500 are both arranged horizontally and are installed and arranged by horizontally extending and utilizing the space at the bottom of the water heater. In this way, the overall height dimension of the filter 500 can be effectively reduced, and the installation requirements of the filter 500 can be met by utilizing the horizontal space at the bottom of the water heater.

[0122] The connection main body 1 of the filter 500 is connected to the external water pipe through the intermediate pipe 4 and is connected to the water inlet pipe 200 on the water heater main body 100 through the installation pipe 11. The filter element 2 and the filter bottle 3 are installed on the corresponding connection ports of the connection main body 1.

[0123] In the filter provided in another embodiment of the present application, in order to facilitate the connection between different water circuits in the connection main body 1, based on the above-mentioned first and second embodiments, a water distributor 5 is further provided, and the water distributor 5 is used to meet the water connection requirements between the intermediate pipe 4, the installation pipe 11, the sewage connection pipe 12, and the filter element 2.

[0124] Specifically: The connection main body 1 is provided with an open installation cavity, an opening end of the installation cavity forms a first connection port 13, and a second connection port 14 is further formed inside the installation cavity at the position of the first connection port 13.

[0125] The water distributor 5 is provided with a first water flow interface 55, a second water flow interface 57, and a third water flow interface 56.

[0126] Among them, the water separator 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 separator 5. An outlet water cavity is formed between the water separator 5 and the inner wall of the connection main body 1, and an inlet water cavity is formed between the water separator 5 and the filter bottle 3; the filter element 2 and the cleaning component 6 are arranged between the water separator 5 and the filter bottle 3, and the cleaning component 6 is rotatably sleeved on the housing 21;

[0127] The intermediate pipe 4 is communicated with the inlet through the first water flow interface 55, the installation pipe 11 is communicated with the outlet through the second water flow interface 57, and the sewage connection pipe 12 is communicated with the inner space of the filter bottle 3 through the third water flow interface 56.

[0128] Specifically, a water separator 5 is built in the connection main body 1. The water separator 5 forms an independent outlet water cavity in the connection main body 1 to be directly connected to the installation pipe 11, and an inlet water cavity is formed between the water separator 5 and the outer filter bottle 3 in the connection main body 1 to meet the connection requirements with the intermediate pipe 4.

[0129] Corresponding first water flow interface 55, second water flow interface 57 and third water flow interface 56 are arranged on the water separator 5 to meet the water path connection requirements of the intermediate pipe 4, installation pipe 11 and sewage connection pipe 12 configured on the connection main body 1.

[0130] During use, the water flow flowing into the inner side of the water separator 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.

[0131] In some embodiments, for the water separator 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.

[0132] Specifically, the water separator 5 has a cover shell structure. The end plate part 501 of the water separator 5 is used to form an outlet water cavity at intervals inside the installation cavity of the connection 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.

[0133] The first water flow interface 55 and the third water flow interface 56 are arranged on the annular part 502 of the water separator 5 to connect the intermediate pipe 4 and the sewage connection pipe 12 respectively.

[0134] Among them, after the water divider 5 is arranged in the connection main body 1, the end of the filter element 2 with an inlet is connected to the second water flow interface 57 and surrounded by the annular part 502. Moreover, a connection and matching structure with a sealed connection is formed between the annular part 502, the filter bottle 3 and the connection main body 1, so that a water inlet cavity is formed between the water divider 5 and the filter bottle 3. In this way, the water conveyed by the middle pipe 4 enters the water inlet cavity, and the water in the water inlet cavity is filtered through the filter net 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 installation pipe 11.

[0135] In some embodiments, a plurality of support columns 503 are arranged on the end plate part 501. The support columns 503 are located in the water outlet cavity and abut against the connection main body 1.

[0136] Specifically, in order to locate the installation position of the water divider 5, a plurality of support columns 503 can be arranged on the end plate part 501. After the water divider 5 is assembled into the installation cavity of the connection 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 divider 5 and the connection main body 1. Among them, the plurality of support columns 503 are distributed around the second water flow interface 57.

[0137] In some embodiments, a diversion channel 551 is further arranged on the inner wall of the annular part 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 part 61.

[0138] 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 part 61 on the cleaning component 6. For this reason, a diversion channel 551 is arranged on the inner wall of the annular part 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 part 61, and the water output from the water outlet holes of the diversion channel 551 will act on the first water flow driving part 61, thereby ensuring that the first water flow driving part 61 bears a sufficient water pressure to drive the cleaning component 6 to rotate.

[0139] Similarly, one end of the cleaning component 6 is provided with a first support part 63. The first support 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. The annular part 502 is located outside the first support part 63.

[0140] The first support part 63 is of a sleeve structure, and a second water flow driving part 64 is arranged on the outer surface of the first support part 63. The first water flow driving part 61 and the second water flow driving part 64 are arranged adjacent to each other along the rotation axis direction of the cleaning component 6;

[0141] Wherein, the first water flow driving part 61 is configured to be driven by the water flow flowing towards the filter bottle 3 to drive the cleaning part 6 to rotate;

[0142] The second water flow driving part 64 is configured to be driven by the water flow flowing towards the sewage connection pipe 12 to drive the cleaning part 6 to rotate.

[0143] Specifically, for the first support part 63, it is located in the space formed by the surrounding of the annular part 502, and a third water flow interface 56 is further provided on the annular part 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 part 64 to increase the rotation speed of the water flow driving the cleaning part 6.

[0144] In another embodiment, in order to reduce the mutual influence between the water flows received by the first water flow driving part 61 and the second water flow driving part 64, the cleaning part 6 is integrally of a sleeve structure, and the first cleaning part 62 is arranged on the inner wall of the cleaning part 6; a plurality of connecting ribs 67 are provided between the first support part 63 and the cleaning part 6, and a water flow interval is formed between two adjacent connecting ribs 67, and the water flow interval is configured to output water flow towards the second water flow driving part 64.

[0145] Specifically, for the diversion channel 551, the water outlet direction of its diversion channel 551 faces the water outlet of the filter bottle 3 to generate a water flow impact on the first water flow driving part 61 in its water outlet direction. The water entering the filter bottle 3 can flow into the space between the cleaning part 6 and the filter element 2 and then flow back into 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 part 61 on the outer wall of the cleaning part 6; and, the water flow flowing out from the water flow interval flows onto the surface of the first support part 63 to generate a water flow impact on the second water flow driving part 64, thereby better meeting the requirement of using the water flow to drive the cleaning part 6 to rotate.

[0146] In some embodiments, a second cleaning part 66 is further provided on the outer wall of the cleaning part 6, and the second cleaning part 66 abuts against the inner bottle wall of the filter bottle 3. The first cleaning part 62 and the second cleaning part 66 are of a strip structure and extend along the rotation axis direction of the cleaning part 6. A hollow structure is provided on the surface of the cleaning part 6. And, in order to ensure reliable support at both ends of the cleaning part 6, a second support part 65 can be provided at the other end of the cleaning part 6, and the second support part 65 abuts against the outer surface of the housing 21 and is configured to cooperate with the first support part 63 to support the cleaning part 6 to rotate on the housing 21. For specific reference, please refer to the description in the first embodiment above, and details will not be repeated here.

[0147] In some embodiments, in order to facilitate the user to intuitively see the usage status of the filter element 2 in the filter bottle 3 and replace the filter element 2 in time under the condition of poor water quality, the filter bottle 3 is of a transparent structure or a translucent structure.

[0148] Specifically, since the filter bottle 3 is made of a transparent or translucent material, when in use, the user can directly observe the state of the filter element 2 in the filter bottle 3, and thus, under the condition of poor water quality, the replacement cycle of the filter element 2 can be shortened.

[0149] A water outlet flow channel 111 is formed in the intermediate pipe 4 to meet the connection requirement between the installation pipe 11 and the water outlet cavity, making the overall structure of the connection body 1 more compact and small, and thus meeting the design requirement of miniaturization.

[0150] The water distributor 5 arranged in the installation cavity of the connection body 1 is used to separate the water outlet cavity and the water inlet cavity in the installation cavity of the connection body 1. A protruding annular spacer 51 is arranged on the annular part on one side of the communication port, so that the water inlet cavity and the water outlet cavity are separated in the installation cavity of the connection body 1.

[0151] In some embodiments, a plug-in part 54 is arranged on the annular part, and a first water flow interface 55 arranged opposite to the communication port is arranged on the plug-in part 54. The first water flow interface 55 is communicated with a diversion channel 551 on the inner wall of the annular part;

[0152] The inner end 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 is communicated with the water inlet cavity through the diversion channel 551.

[0153] During the assembly process, the inner end of the intermediate pipe 4 is inserted into the first water flow interface 55, so that the intermediate pipe 4 is communicated with the water inlet cavity through the diversion channel 551. Moreover, the intermediate pipe 4 and the plug-in part 54 cooperate with each other to isolate the inner port of the intermediate pipe 4 from the water outlet cavity, thus meeting the effective isolation between the water inlet cavity and the water outlet cavity.

[0154] In addition, by configuring the plug-in part 54 on the annular part, it can better meet the flow requirement of the water outlet flow by borrowing the internal flow channel of the intermediate pipe 4 for the installation pipe 11. At the same time, during the overall assembly of the filter, it is convenient to effectively connect the inner end of the intermediate pipe 4 to the water inlet cavity while effectively isolating it from the water outlet cavity, facilitating the quick and accurate assembly of the filter.

[0155] In order to further increase the space at the water inlet of the installation pipe 11, a recessed structure 41 may be provided on the intermediate pipe 4. The recessed structure 41 is arranged opposite to the water inlet of the installation pipe 11. In this way, the water received and sent by the water outlet flow channel 111 can flow more smoothly into the installation pipe 11 at the recessed structure 41 to ensure the smooth flow of the water outlet flow.

[0156] Embodiment 4, as Figure 11 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 may be a water tank of an electric water heater, a heat pump water heater, or a solar water heater.

[0157] 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.

[0158] 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 filter 500 may 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 by the water supply pipe through the filter 500.

[0159] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some of the technical features can be equivalently replaced; 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.
