In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0026] As Figure 1 and Figure 2 shown, the present application provides an appliance, which includes a water heater main body 100. The representation entity of the water heater main body 100 can be an electric water heater, or a water tank of a heat pump water heater, or a water tank of a solar water heater.

[0027] 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.

[0028] Wherein, 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 water treatment device 500 can be added between the water inlet pipe 200 of the water heater and the water supply pipe in the user's home, so as to filter the water output from the water supply pipe through the water treatment device 500.

[0029] Embodiment 1, as Figures 3 - 8 shown, generally, the water treatment device includes a connection main body 1 and a filtering component. The filtering component includes a filter element 2 and a filter bottle 3. The connection 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 connection main body 1 is also used to install the filter element 2 and the filter bottle 3 of the filtering component.

[0030] The filter bottle 3 and the filter element 2 are arranged on the connection 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. Wherein, a water inlet connecting pipe 11 and a water outlet connecting pipe 12 are arranged on the connection 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.

[0031] In addition, since the filter element 2 is installed between the connection 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 water treatment device further 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.

[0032] 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, and the first cleaning part 62 is configured to follow the cleaning component 6 to rotate to scrape the filter net 24 on the housing 21.

[0033] Correspondingly, in order to discharge the sewage formed by cleaning in time after the filter element 2 is cleaned by the cleaning component 6, a sewage discharge connecting pipe 17 is further arranged on the connection body 1, and the sewage discharge connecting pipe 17 is communicated with the internal space of the filter bottle 3.

[0034] Specifically, in the actual use process, when the water treatment device is in normal filtration use, water enters the connection 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 is output 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 for use in a water heater.

[0035] After long-term use, the surface of the filter net will be covered with dirt such as sediment filtered out, so that the filtering ability of the filter net will decrease and the filtering efficiency will be reduced. 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.

[0036] Specifically, first open the sewage connection pipe 17. The water introduced by the water inlet connection pipe 11 enables the water in the filter bottle 3 to be discharged via the sewage connection pipe 17. During the flow of water in the water treatment device, the water flow acts on the first water flow driving part 61 of the cleaning part 6, causing the first water flow driving part 61 to drive the cleaning part 6 to rotate. In this way, the first cleaning part 62 on the rotating cleaning part 6 can be used to scrape the filter screen of the filter element 2, so as to clean the dirt on the surface of the filter screen, thereby restoring the filtering ability of the filter screen, ensuring that the water treatment device can maintain a high filter screen ability stably for a long time, and thus extending the overall service life of the water treatment device.

[0037] 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 connection body 1, and at least part of the water flows from the connection body 1 into the filter bottle 3 and drives the first water flow driving part 61 to drive the cleaning part 6 to rotate on the housing 21 so as to clean the filter net 24 through the first cleaning part 62. The water flowing into the filter bottle 3 flows out through the surface of the housing 21 into the sewage connection pipe 17.

[0038] 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 connection body 1 under the action of the water flowing out of the sewage connection pipe 17.

[0039] By configuring the cleaning part 6 on the filter element 2, the cleaning part 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 water treatment device to drive the cleaning part 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 water treatment device, open the sewage connection pipe 17, and use the water flow flowing into the water treatment device to drive the cleaning part 6 to rotate to clean the filter net 24 of the filter element 2, reducing the reduction of the filtration efficiency of the water treatment device due to the blockage of the filter net 24 of the filter element 2, and realizing the improvement of the filtration efficiency of the water treatment device and the extension of the service life.

[0040] In one embodiment, in order to ensure that the cleaning part 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 part 6, and the first supporting part 63 abuts against the outer surface of the housing 21 and is configured to support the cleaning part 6 to rotate on the housing 21.

[0041] 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 connecting to the 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.

[0042] In some embodiments, 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.

[0043] In addition, 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; Among them, 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.

[0044] Specifically, for the water flow flowing inside the water treatment device, it is divided into the water flow that enters the main body 1 from the water inlet connection pipe 11 and flows towards the filter bottle 3, and this water flow can act on the first water flow driving portion 61.

[0045] Meanwhile, for the water flow flowing inside the water treatment device, it is also divided into the water flow that flows from the filter bottle 3 to the 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.

[0046] 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.

[0047] 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.

[0048] Specifically, the water flow in the water treatment device 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.

[0049] Among them, the guiding rib strips are arranged obliquely with respect to the rotation axis of the cleaning component 6. The oblique arrangement direction of the guiding rib strips is matched with the water flow acting on them, so that the guiding rib strips respectively constituting the first water flow driving part 61 and the second water flow driving part 64 can apply a rotational driving force in the same direction to the cleaning component.

[0050] In another embodiment, a second supporting part 65 is provided at the other end of the cleaning component 6. 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.

[0051] Specifically, the other end of the cleaning component 6 is further configured with a second supporting part 65. By the mutual cooperation of the first supporting part 63 and the second supporting part 65, the cleaning component 6 is effectively installed on the housing 21.

[0052] Among them, for the specific structural forms of the second supporting part 65, there can be multiple ways. For example: the second supporting part 65 can also adopt a sleeve structure to sleeved on the housing 21, or the second supporting part 65 is multiple supporting columns 503 to abut against the housing 21.

[0053] 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.

[0054] 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 multiple first cleaning parts 62 can be arranged on the inner wall of the cleaning component 6.

[0055] In addition, a second cleaning part 66 can also be provided on the outer wall of the cleaning component 6. The second cleaning part 66 abuts against the inner wall of the filter bottle 3. To clean the inside of the filter bottle 3 through the second cleaning part 66.

[0056] 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.

[0057] 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.

[0058] In another embodiment of the present application, for the sewage discharge connecting pipe 17, an independent valve assembly 7 can be externally connected to control the opening and closing of the controller, or the valve assembly 7 can be integrally provided on the sewage discharge connecting pipe 17.

[0059] Specifically, the valve assembly 7 includes a valve body 71 and a rotating member 72. The valve body 71 is rotatably arranged in the sewage discharge connecting pipe 17. The rotating member 72 is arranged on the valve body 71, and the rotating member 72 extends outside the pipe wall of the sewage discharge connecting pipe 17. The valve body 71 is configured to open and close the sewage discharge connecting pipe 17.

[0060] Specifically, the valve body 71 is located in the sewage discharge connecting pipe 17 and can rotate in the sewage discharge connecting pipe 17. The opening and closing of the sewage discharge connecting pipe 17 are controlled 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 sewage discharge connecting pipe 17, and then the valve body 71 in the sewage discharge connecting pipe 17 is driven to rotate by driving the rotation of the rotating member 72.

[0061] 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 perpendicular to its axis on the sphere. The position of the water flow hole is controlled by rotating the sphere to realize the opening and closing of the exhaust connecting pipe; or the valve body 71 can be a valve plate, and the opening and closing of the exhaust connecting pipe are controlled by rotating the valve plate.

[0062] 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 17 and is configured to drive the rotating member 72 to rotate.

[0063] Specifically, the driving handle 73 is rotatably installed on the exhaust connecting pipe. When the user rotates the driving handle 73 by hand, the rotating member 72 can be driven to drive the valve body 71 to rotate, so as to realize the opening and closing of the sewage discharge connecting pipe 17.

[0064] 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, and an active gear structure 75 is provided on the driving handle 73. The passive gear structure 74 and the active gear structure 75 are engaged.

[0065] Specifically, a passive gear structure 74 is provided at the end of the rotating member 72 extending outside the sewage discharge connecting pipe 17. At the same time, an active gear structure 75 is configured on the driving handle 73. By rotating the driving handle 73, the passive gear structure 74 is engaged with the active gear structure 75 to achieve labor-saving driving of the rotation of the rotating member 72.

[0066] In another embodiment, to facilitate the integrated assembly of the drive handle 73 onto the sewage connection pipe 17, the valve assembly 7 further includes a connecting member 76. The connecting member 76 is disposed at the pipe opening of the sewage connection pipe 17. A sewage discharge hole 761 is provided on the connecting member 76, and the sewage discharge hole 761 communicates with the sewage connection pipe 17. An installation hole 731 is provided on the drive handle 73, and the connecting member 76 and / or the sewage connection pipe 17 is inserted into the installation hole 731.

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 drive handle 73 is reliably installed on the sewage connection pipe 17 to meet the requirements of integrated installation.

[0068] Among them, for the drive handle 73, it can be directly sleeved outside the sewage connection pipe 17 to meet the requirements of rotatable installation. Or, a stepped structure can be provided on the connecting member 76, and the drive handle 73 is rotatably installed on the stepped structure through the installation hole 731 to limit the drive handle 73 by the stepped surface of the stepped structure.

[0069] In another embodiment of the present application, a decorative cover 400 is further provided on the water heater main body 100.

[0078] Specifically, a water distributor 5 is built into the connection body 1, and the water distributor 5 forms an independent outlet cavity in the connection body 1 to be directly connected to the water outlet connection pipe 12, while an inlet cavity is formed between the water distributor 5 and the outer filter bottle 3 in the connection body 1 to meet the connection requirements with the water inlet connection pipe 11.

[0079] A first water flow interface 55, a second water flow interface 57, and a third water flow interface 56 are correspondingly provided on the water distributor 5 to meet the waterway connection requirements for connecting the water inlet connecting pipe 11, the water outlet connecting pipe 12, and the sewage connecting pipe 17 configured on the main body 1.

[0080] 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, causing the first water flow driving part 61 to drive the cleaning part 6 to rotate on the housing 21 under the drive of the water flow, and then the first cleaning part 62 is driven to rotate along with the cleaning part 6 to scrape the filter net 24 on the housing 21.

[0081] 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 provided on the annular part 502, and the second water flow interface 57 is provided on the end plate part 501.

[0082] Specifically, the water distributor 5 has a cover structure. The end plate part 501 of the water distributor 5 is used to form a water outlet cavity at intervals inside the installation cavity of the connecting main body 1, and the water outlet cavity can be connected to the inlet of the filter element 2 through the second water flow interface 57.

[0083] On the annular part 502 of the water distributor 5, a first water flow interface 55 and the third water flow interface 56 are configured to connect the water inlet connecting pipe 11 and the sewage connecting pipe 17 respectively.

[0084] Among them, after the water distributor 5 is arranged in the connecting 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 part 502. Moreover, a connection and cooperation structure with a sealed connection is formed between the annular part 502, the filter bottle 3, and the connecting main body 1, so that a water inlet cavity is formed between the water distributor 5 and the filter bottle 3. In this way, the water conveyed by the water inlet connecting pipe 11 enters the water inlet cavity, 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, and 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.

[0085] In certain embodiments, a plurality of support columns 503 are provided on the end plate part 501, and the support columns 503 are located in the water outlet cavity and abut against the connecting main body 1.

[0086] Specifically, in order to position the installation position of the water distributor 5, a plurality of support columns 503 can be provided on the end plate part 501. After the water distributor 5 is assembled and connected to the installation cavity of the connecting 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 distributor 5 and the connecting main body 1. Among them, the plurality of support columns 503 are distributed around the second water flow interface 57.

[0087] In some embodiments, a diversion channel 551 is further provided 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.

[0088] 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 purpose, a diversion channel 551 is provided 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.

[0089] Similarly, a first support portion 63 is provided at one end of the cleaning component 6. 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, and the annular portion 502 is located outside the first support portion 63.

[0090] 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 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 in the direction of the sewage connection pipe 17 to drive the cleaning component 6 to rotate.

[0091] 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 flowing out from the third water flow interface 56 can be further used to act on the second water flow driving portion 64 to increase the rotation speed of the water flow driving the cleaning component 6.

[0092] 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 adjacent two of the connecting ribs 67. The water flow interval is configured to output water flow towards the second water flow driving portion 64.

[0093] Specifically, for the diversion channel 551, the water outlet direction of the 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 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 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 component 6; moreover, the water flowing out from the water flow interval flows onto the surface of the first supporting 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 component 6 to rotate.

[0094] In some embodiments, a second cleaning part 66 is further provided 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. 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. The surface of the cleaning component 6 is provided with a hollow structure. And, in order to ensure that both ends of the cleaning component 6 obtain reliable support, a second supporting part 65 can be provided at the other end of the cleaning component 6, 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. For specific details, reference can be made to the description in the first embodiment above, and details will not be elaborated here.

[0095] In some embodiments, in order to facilitate the user to directly observe the usage state of the filter element 2 in the filter bottle 3 and replace the filter element 2 in a timely manner under the condition of poor water quality, the filter bottle 3 is made of a transparent structure or a semi-transparent structure.

[0096] Specifically, since the filter bottle 3 is made of a transparent or semi-transparent 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.

[0097] Embodiment 3. In another embodiment of the present application, for the connection main body, it can be an integral structure. For the convenience of processing, the connection main body can also adopt a split structure, which will be described below with reference to the accompanying drawings.

[0098] As Figure 7As shown, the connecting body 1 includes a first connecting member 15 and a second connecting member 16. The first connecting member 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 connecting member 16. The second connecting member 16 is provided with a first connection port 13, a second connection port 14, and a sewage connecting pipe 17. The first connecting member 15 and the second connecting member 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.

[0099] Specifically, for the connecting 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 connecting member 15, and the sewage connecting pipe 17 is provided on the second connecting member 16. In order to meet the requirements of water inlet and water outlet inside the connecting body 1 and meet the installation design requirements of structural compactness and miniaturization, the following structural improvements are made to the connecting body 1.

[0100] The connecting body 1 includes a first connecting member 15 and a second connecting member 16. The first connecting member 15 is provided with the outwardly extending water inlet connecting pipe 11 and the water outlet connecting pipe 12. A first flow channel 151 and a second flow channel 152 arranged side by side are formed in the first connecting member 15. The water inlet connecting pipe 11 is communicated with the first flow channel 151, and the water outlet connecting pipe 12 is communicated with the second flow channel 152. An installation cavity is formed on the second connecting member 16. A third flow channel 161 and a fourth flow channel 162 arranged side by side are formed in the second connecting member 16. The third flow channel 161 is communicated with the first flow channel 151, and the fourth flow channel 162 is communicated with the second flow channel 152. Wherein, the water inlet connecting pipe 11 is communicated with the water inlet cavity through the first flow channel 151 and the third flow channel 161, and the water outlet connecting pipe 12 is communicated with the water outlet cavity through the second flow channel 152 and the fourth flow channel 162.

[0101] Specifically, for the connection body 1, since it needs to meet the requirements of two independent water flow paths for water inlet and outlet inside, in order to simplify the processing difficulty, a water inlet connecting pipe 11 and a water outlet connecting pipe 12 are provided on the first connecting member 15. Correspondingly, a first flow channel 151 and a second flow channel 152 are formed inside the first connecting member 15 to connect the water inlet connecting pipe 11 and the water outlet connecting pipe 12 respectively. The second connecting member 16 forms an installation cavity to meet the installation requirements of the filter element 2 and the filter bottle 3. Similarly, in order to meet the water flow requirements of water inlet and outlet, a third flow channel 161 and a fourth flow channel 162 are formed inside the second connecting member 16.

[0102] During use, the water output by the external water pipe enters the water inlet connecting pipe 11, flows into the water inlet cavity through the first flow channel 151 and the third flow channel 161. The water in the water inlet cavity enters the interior of the filter element 2 from the inlet 201 of the filter element 2 for further filtration treatment and then is input into the water outlet cavity from the outlet 202. The water in the water outlet cavity is output from the water outlet connecting pipe 12 through the fourth flow channel 162 and the second flow channel 152 and enters the water inlet pipe 200 of the water heater.

[0103] In one embodiment, a stepped surface (not marked) is formed in the installation cavity, and the stepped surface is located between the port of the third flow channel 161 and the port of the fourth flow channel 162; an annular rib 141 is provided on the stepped surface, and the annular rib 141 surrounds to form the second connection port 14.

[0104] Specifically, since the water inlet cavity is communicated with the third flow channel 161 and the water outlet cavity is communicated with the fourth flow channel 162, in order to effectively isolate the third flow channel 161 and the fourth flow channel 162. A stepped surface is provided between the third flow channel 161 and the fourth flow channel 162, and an annular rib 141 is formed on the stepped surface. The filter element 2 is installed through the second connection port 14 formed by surrounding of the annular rib 141. Further, the third flow channel 161 and the fourth flow channel 162 are isolated by the annular rib 141, thereby realizing the isolation between the water inlet cavity and the water outlet cavity in the connection body 1.

[0105] By adopting a split design for the connection body, the first connecting member correspondingly forms a first flow channel and a second flow channel arranged side by side to meet the requirements of the water path connection of the water inlet connecting pipe and the water outlet connecting pipe. The second connecting member is used to install the filter element and the filter bottle. For the filter element and the filter bottle, they are arranged horizontally as a whole. In this way, after the pre-treatment device is installed on the water inlet pipe of the water heater, the filter element and the filter bottle will be installed and arranged by using the horizontal space at the bottom of the water heater, thereby reducing the occupied space of the pre-treatment device in the height direction. In this way, the pre-treatment device can be hidden inside the decorative cover of the water heater to optimize the overall appearance effect and improve the user experience.
