[0025] As Figure 1 and Figure 5 shown, the present application provides a water heater, which includes: A water tank 100, a water storage cavity is formed inside the water tank 100, a water inlet pipe 200 and a water outlet pipe 300 are provided on the water tank 100, and a scale inhibitor module 130 is also provided in the water storage cavity; An electric heating component 600, the electric heating component 600 includes a flange 610, an electric heating tube 620 and a graphic collector 630. The electric heating tube 620 is arranged on the flange 610. An installation pipe 640 is also provided on the flange 610. The installation pipe 640 penetrates through the flange 610. A transparent cover 650 is provided at the inner pipe orifice of the installation pipe 640. The graphic collector 630 is located in the installation pipe 640 and is arranged opposite to the transparent cover 650; Wherein, the flange 610 is arranged on the water tank 100, and the electric heating tube 620 and the installation pipe 640 extend into the water storage cavity.

[0026] Specifically, during actual use, the user can collect image information in the water storage cavity formed inside the water tank 100 through the graphic collector 630, and can intuitively observe the usage situation of the scale inhibitor module 130 in the water storage cavity according to the collected image information.

[0027] The graphic collector 630 is located in the installation pipe 640 and is protected by the transparent cover 650, which can ensure the reliable use of the graphic collector 630 while meeting the requirements of image collection.

[0028] By additionally configuring an installation pipe 640 extending into the water storage cavity on the flange 610, and a transparent cover 650 is provided at the end of the installation pipe 640 located in the water storage cavity. In this way, the graphic collector 630 can be placed in the installation pipe 640, and the graphic collector 630 can collect the image information in the water storage cavity of the water tank 100 through the transparent cover 650, so as to facilitate the user to timely understand the usage status of the scale inhibitor module 130 in the water storage cavity, and can perform maintenance and replacement in time when the scale inhibitor module 130 is nearly used up, realizing the visual design of the internal water storage cavity of the water heater to improve the user experience.

[0029] In one embodiment, the water tank 100 includes a housing 110 and an inner tank 120. The inner tank 120 is located in the housing 110, and the inner tank 120 forms the water storage cavity. The flange 610 is provided on the inner tank 120; a display screen (not marked) is also provided on the housing 110, and the display screen is configured to display the image collected by the graphic collector 630.

[0030] Specifically, by configuring a display screen on the housing 110, when the user needs to observe the internal image of the water storage cavity, the image information collected by the graphic collector 630 can be displayed via the display screen. Among them, the graphic collector 630 can adopt conventional image collection devices such as cameras, which will not be limited and elaborated here.

[0031] In another embodiment, in order to improve the quality of image collection, a lighting lamp 660 is further provided on the flange 610, and the lighting lamp 660 is configured to illuminate the internal space of the water storage cavity.

[0032] Specifically, when collecting the image of the water storage cavity inside the water tank 100 through the graphic collector 630, the lighting lamp 660 can be started synchronously to illuminate the internal space of the water storage cavity, so as to obtain a good image collection effect.

[0033] In some embodiments, in order to detect the water quality in the water tank 100 in real time, a water quality sensor is further provided on the flange 610.

[0034] Based on the above technical solutions, optionally, after configuring the graphic collector 630 for the water heater, during use, the water quality and water level in the water storage cavity can be automatically monitored by using the image information collected by the graphic collector 630 by means of image recognition to control the operation of the water heater.

[0035] Specifically, the control method of the water heater includes: collecting the image information in the water storage cavity through the graphic collector 630 and performing image recognition and comparative analysis with the initially collected image information. If the dimensional change amount of the scale inhibitor module 130 is greater than the first set threshold, the user is reminded to maintain the scale inhibitor module 130.

[0036] Specifically, take a photo when the initial inner tank 120 is full of water. When a specific water consumption or a specific duration is reached, take a photo again. Analyze the current photo and the initial photo. When the difference between the two photos is too large (or the difference value can be calculated through analysis and compared with the normal value range. If the difference value exceeds the normal value range), it is determined that the inner tank 120 is unhealthy and needs to be cleaned.

[0037] Taking the magnesium rod of the scale prevention module 130 as an example, when a specific water consumption or a specific duration is reached, take a photo again. Analyze the situation of the magnesium rod in the current photo and the initial photo. When it is determined that the size of the magnesium rod has changed significantly, remind the user to replace the magnesium rod.

[0038] In another embodiment, the control method of the water heater further includes: after the initial inner water tank 100 is full of water, the graphic collector 630 is used to collect the image information in the water storage cavity to obtain the initial liquid level height in the water storage cavity. During the later use process, if the value that the real-time liquid level height collected by the graphic collector 630 in the water storage cavity is lower than the initial liquid level height exceeds the second set threshold, the electric heating tube 620 is automatically powered off and an alarm is given.

[0039] Specifically, when the initial inner tank 120 is full of water, take a photo of the highest liquid level line in the tank. Take this line as the warning line. After each water use cycle ends and reheating, take a photo and compare the front and rear liquid level lines. When it is lower than the warning line by more than the set threshold, give a warning and at the same time cut off the heating circuit to realize the reminder of the dry burning prevention function.

[0040] Embodiment 2, as Figures 6 - 11 shown, in another embodiment of the present application, a decorative cover 400 is further provided on the water tank 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; For the filter 500, the overall filtering component is arranged horizontally and hidden on the back of the decorative cover 400.

[0041] Specifically, the water inlet pipe 200 configured for the water heater is used to satisfy the internal water inlet, and the water outlet pipe 300 is used to output the heated water to the water use terminal. For the water entering the water inlet pipe 200, the water quality can be filtered by the filter 500 first to improve the water inlet quality entering the water heater.

[0042] Among them, since the filter 500 is installed on the water inlet pipe 200, in order to make the filter 500 achieve a hidden installation method, the installation structure of the filter 500 is improved and designed.

[0043] Specifically, both the filter element 2 and the filter bottle 3 of the filter 500 are arranged horizontally and installed horizontally by extending 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 horizontal space at the bottom of the water heater can meet the installation requirements of the filter 500.

[0044] The installation main body 1 of the filter 500 is connected to the external water pipe through the water inlet connecting pipe 11 and is connected to the water inlet pipe 200 on the water tank 100 through the water outlet connecting pipe 12. The filter element 2 and the filter bottle 3 are installed on the corresponding connection ports of the installation main body 1.

[0045] The filter 500 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.

[0046] 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. Wherein, 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.

[0047] 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 filter also 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.

[0048] 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 along with the cleaning component 6 to scrape the filter net 24 on the housing 21.

[0049] 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 also arranged on the installation main body 1. The sewage discharge connecting pipe 17 is communicated with the internal space of the filter bottle 3.

[0050] Specifically, during actual use, when the filter is in normal filtering operation, 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 screen on the housing 21 in the filter bottle 3, enters 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 to the water heater for use.

[0051] 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 decrease, and thus the filtering efficiency will be reduced. At this time, the sewage discharge connecting pipe 17 can be opened to clean the filter screen of the filter element 2 through the cleaning component 6.

[0052] Specifically, first open the sewage discharge connecting pipe 17, and the water introduced by the water inlet connecting pipe 11 enables the water in the filter bottle 3 to be discharged through the sewage discharge connecting pipe 17. During the flow of the water in the 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 surface of 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, so as to ensure that the filter can maintain a high filtering ability stably for a long time, and thus extend the overall service life of the filter.

[0053] Among them, when the sewage discharge connecting pipe 17 is in an open state, the water introduced from the water inlet connecting 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 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 and is discharged through the sewage discharge connecting pipe 17.

[0054] Specifically, during use, when the sewage discharge connecting pipe 17 is opened, the water introduced by the water inlet connecting pipe 11 will enter the filter bottle 3. In addition, part of the water flow introduced by the water inlet connecting pipe 11 will be directly discharged from the sewage discharge connecting pipe 17 inside the installation main body 1 under the action of the water output of the sewage discharge connecting pipe 17.

[0055] By disposing a cleaning component 6 on the filter element 2, a first water flow driving part 61 and a first cleaning part 62 are disposed on the cleaning component 6. 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 17 is opened, and the water flow flowing into the filter is used to drive the cleaning component 6 to rotate to clean the filter net 24 of the filter element 2, reducing the reduction of the filtering efficiency of the filter due to the blockage of the filter net 24 of the filter element 2 by dirt, and achieving the improvement of the filtering efficiency of the filter and the extension of the service life.

[0056] 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 provided at one end of the cleaning component 6. 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.

[0057] 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 installation main body 1, and the first support part 63 and the first cleaning part 62 abutting against the filter net cooperate to meet the requirement that the cleaning component rotates on the housing 21.

[0058] 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.

[0059] 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 provided 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; 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; 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 17 to drive the cleaning component 6 to rotate.

[0060] Specifically, for the water flow flowing inside the 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 part 61.

[0061] At the same time, for the water flow flowing inside the 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 part 64.

[0062] 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.

[0063] 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.

[0064] 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 the reaction force of the water flow is used to drive the cleaning component to rotate.

[0065] Wherein, 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0078] 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 part 72 to rotate.

[0079] Specifically, the driving handle 73 is rotatably installed on the exhaust connecting pipe. The user rotates the driving handle 73 by hand, and can control the rotating part 72 to drive the valve body 71 to rotate, so as to realize the opening and closing of the sewage discharge connecting pipe 17.

[0085] Embodiment Three, as Figures 6 - 13 shown, in the filter provided by another embodiment of the present application, in order to facilitate the connection between different water circuits within the installation main body 1, based on the above-mentioned Embodiment One, a water distributor 5 is further provided, and the water distributor 5 is used to meet the water connection requirements among the water inlet connection pipe 11, the water outlet connection pipe 12, the sewage connection pipe 17, and the filter element 2.

[0086] Specifically, the installation main body 1 is provided with an open installation cavity. The opening end of the installation cavity is provided with a first connection port 13, and a second connection port 14 is further provided inside the installation cavity at the position of the first connection port 13.

[0087] 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.

[0088] 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 internal space of the filter bottle 3 through the third water flow interface 56.

[0089] Specifically, a water distributor 5 is built in 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, and 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 requirement with the inlet connection pipe 11.

[0090] Correspondingly, 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 to meet the waterway 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.

[0091] 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, and then the first cleaning part 62 is driven to rotate with the cleaning component 6 to scrape the filter net 24 on the housing 21.

[0092] 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.

[0093] Specifically, the water diverter 5 is in the structure of a housing. The end plate portion 501 of the water diverter 5 is used to form a water outlet cavity at intervals inside the installation cavity of the installation 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.

[0094] On the annular portion 502 of the water diverter 5, a first water flow interface 55 and the third water flow interface 56 are arranged to connect the water inlet connecting pipe 11 and the sewage connecting pipe 17 respectively.

[0095] Among them, after the water diverter 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. And a connection and cooperation 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 diverter 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 by the filter screen 24 of the filter element 2 and output from the outlet of the filter element 2, and the water output by 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.

[0096] 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.

[0097] Specifically, in order to position the installation position of the water diverter 5, a plurality of support columns 503 can be arranged on the end plate portion 501. After the water diverter 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 diverter 5 and the installation main body 1. Among them, the plurality of support columns 503 are distributed around the second water flow interface 57.

[0098] 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.

[0099] 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.

[0100] Similarly, one end 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.

[0101] The first support portion 63 is of a sleeve structure. 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 connecting pipe 17 to drive the cleaning component 6 to rotate.

[0102] Specifically, for the first support portion 63, it is located in the space formed by the surrounding of the annular portion 502. The annular portion 502 is further provided with a third water flow interface 56. In this way, the water flow 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.

[0103] 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. 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. 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.

[0104] 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 portion 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 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 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.

[0105] 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. And, 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 reference, please refer to the description in the first embodiment above, and details will not be elaborated here.

[0106] In some embodiments, to facilitate the user to visually observe 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 of a transparent structure or a translucent structure.

[0107] Specifically, since the filter bottle 3 is made of a transparent or translucent 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.

[0108] Embodiment 3, in another embodiment of the present application, for the installation main body, it can be of 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 drawings.

[0109] 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.

[0110] 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.

[0111] In order to meet the requirements of water inlet and outlet inside the installation main body 1 and satisfy the installation design requirements of compact and miniaturized structure, the following structural improvements are made to the installation main body 1.

[0112] 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 back to back; A communication port is provided on the second installation component 16, and the communication port communicates with the installation cavity.

[0113] The 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 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, and the inner pipe orifice of the intermediate pipe 4 communicates with the water inlet cavity.

[0114] 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 of the second installation component 16 through the auxiliary connecting pipe 153.

[0115] 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, the intermediate pipe 4 can form an auxiliary flow channel 111 with the inner pipe wall of the water inlet connecting pipe 11. The first installation component 15 is 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, so that the auxiliary flow channel 111 communicates with the water outlet cavity through the communication port. 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 to achieve communication with the water inlet cavity.

[0116] The auxiliary flow channel 111 is formed in the water inlet connecting pipe 11 by using the intermediate pipe 4 to meet the communication 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.

[0117] 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, so that the water inlet cavity and the water outlet cavity are separated in the installation cavity of the second installation component 16.

[0118] In some embodiments, a plug-in portion 54 is provided on the annular portion. A first water flow interface 55 disposed opposite to the communication port 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.

[0119] 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.

[0120] 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. At the same time, during the overall assembly of the filter, it is convenient to effectively connect the inner end portion of the intermediate pipe 4 to the water inlet cavity while also meeting effective isolation from the water outlet cavity, facilitating the quick and precise assembly of the filter.

[0121] 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 disposed 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.

[0122] 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, those of ordinary skill in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
