[0024] Example 1, as Figures 1-6 As shown, one embodiment of this application provides a filter temperature control module, including: A thermostatic valve 600, wherein the thermostatic valve 600 has a first inlet 610, a second inlet 620 and a main outlet 630; A 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 via the first pair of interfaces 40 and then output it from the second pair of interfaces 10. A connecting pipe assembly 700 includes a multi-port pipe 710 and a guide pipe 720. The multi-port pipe 710 has a main inlet 711, a second outlet 712, a third outlet 713, and an installation port 714. The guide pipe 720 is inserted into the multi-port pipe 710 and is sealed to the main inlet 711. A water flow channel is formed between the inner walls of the guide pipe 720 and the multi-port pipe 710. The second outlet 712 and the third outlet 713 are respectively connected to the water flow channel. The second pair of interfaces 10 is connected to the mounting port 714, the guide pipe 720 is sealed to the first pair of interfaces 40, the water flow channel is connected to the second pair of interfaces 10, and the second outlet 712 is connected to the second inlet 620.

[0025] Specifically, the connecting 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 the bypass pipe 800 to complete the assembly of the filter thermostatic module; and the filter 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 connected to the water inlet pipe of the water heater through the third water outlet 713 of the connecting pipe group 700.

[0026] Among them, for the filter 500, it is fixedly installed on the mounting port 714 of the multi-way pipe 710, and the first connecting port 40 is communicated with the total water inlet 711 through the flow guide pipe 720 to make the tap water flow into the filter 500, and then the second connecting port 10 is communicated with the mounting port 714 to realize the communication with the water flow channel outside the flow guide pipe 720, so that the water filtered by the filter 500 is output through the second connecting port 10 and flows into the water flow channel, and then the filtered water is output from the second water outlet 712 and the third water outlet 713 according to the needs through the water flow channel.

[0027] Since the flow guide pipe 720 is inserted into the multi-way pipe 710 to meet the requirements of the filter 500 for water inlet and outlet, the compact design is realized, and at the same time, for the multi-way pipe 710, it can also meet the connection requirements of the thermostatic valve 600, the tap water pipe and the water heater, and the connecting pipe group 700 itself is compact, which is more conducive to reducing the overall volume of the filter thermostatic module to reduce the space occupation.

[0028] In an 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; the total water inlet 711 is arranged on the first pipe body 715, the second water outlet 712 is arranged on the second pipe body 716, the third water outlet 713 is arranged on the third pipe body 717, and the mounting port 714 is arranged on the fourth pipe body 718; wherein the fourth pipe body 718 and the first pipe body 715 are oppositely arranged, the third pipe body 717 is arranged 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.

[0029] Specifically, for the multi-way pipe 710, it itself has a plurality of pipe bodies, and the total water inlet 711, the second water outlet 712, the third water outlet 713 and the mounting port 714 are formed through the plurality of pipe bodies, and at the same time, the connection and installation requirements are met.

[0030] The first pipe body 715 is further provided with a shielding plate 719, which is extended into the fourth pipe body 718 from the first pipe body 715; the shielding plate 719 is provided with an outward turning edge structure 7191 connected to the inner wall of the fourth pipe body 718, and is further provided with a water passing hole 7192 on the outward turning edge structure 7191; an insertion hole is formed between the inner surface of the shielding plate 719 and the inner wall of the fourth pipe body 718, and the insertion hole is communicated with the total water inlet 711. The shielding plate 719 is shielded on the inner side of the second pipe body 716 and is configured to separate the second water outlet 712 from the total water inlet 711. The one end of the flow guide pipe 720 is sealingly inserted into the insertion hole, and the other end of the flow guide pipe 720 is sealingly inserted into the first connecting port 40.

[0031] Specifically, for the total water inlet 711, the water introduced thereby needs to be input into the filter 500 through the flow guide pipe 720, and then the filtered water flow is output from the filter 500 back to the water flow channel. The shielding plate 719 can separate the second water outlet 712 from the first pipe body 715, so that after the flow guide pipe 720 is loaded and connected to the filter 500, the total water inlet 711 and the second water outlet 712 are not directly communicated.

[0032] In addition, for the water flowing into the water flow channel, the outward turning edge structure 7191 is located in the water flow channel, so that the second water outlet 712 is communicated with the water flow channel through the water passing hole 7192, thereby satisfying 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.

[0033] In an embodiment, the axis of the fourth pipe body 718 is offset relative to the axis of the first pipe body 715, and the flow guide pipe 720 has an inclined structure.

[0034] Specifically, for the multi-pass pipe 710, the first pipe body 715 and the fourth pipe body 718 are relatively offset, so that the first pipe body 715 can form the shielding plate 719 to shield the second pipe body 716.

[0035] The flow guide pipe 720 includes a first straight pipe segment 721, a second straight pipe segment 722, and an inclined pipe segment 723 connected between the first straight pipe segment 721 and the second straight pipe segment 722. The end of the first straight pipe segment 721 is inserted into the insertion hole, and the end of the second straight pipe segment 722 extends to the outside of the mounting port 714 and is inserted into the first connecting port 40.

[0036] Specifically, the two straight pipe sections of the guide pipe 720 can better meet the requirements of sealing and plugging with the insertion hole and the first pair of interfaces 40, while 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.

[0037] In addition, the outer periphery of the second straight pipe section 722 is provided with a plurality of first support ribs 724, which abut against the inner wall of the fourth pipe body 718. And / or, the outer periphery of the inclined pipe section 723 is provided with a plurality of second support ribs 725, which abut against the inner wall of the fourth pipe body 718.

[0038] In another embodiment, the multi-port pipe 710 has a fifth pipe body 7101, on which a pressure relief valve 730 is provided, and the fifth pipe body 7101 is connected to the first pipe body 715.

[0039] Specifically, the pressure relief valve 730 is designed to meet the normal pressure relief requirements of the water heater.

[0040] Example 2: Based on Example 1 above, the filter can adopt a conventional filter structure. Similarly, in order to achieve automatic cleaning of the filter element, the filter can be improved as follows. For example... Figures 6-8 As shown, the filter in this embodiment includes a connecting body 1 and a filter assembly, which includes a filter element 2, a filter bottle 3 and an intermediate tube 4.

[0041] An installation cavity is formed in the connecting body 1. The connecting 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 pair of interfaces 10, and the installation pipe 11 is connected to the installation cavity through a communication port.

[0042] 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 filter bottle 3 of the filter assembly.

[0043] The filter bottle 3 and the filter element 2 are disposed on the connecting body 1. The filter bottle 3 covers the filter element 2. The intermediate tube 4 is connected to the inlet. The mounting tube 11 is connected to the outlet. The filter element 2 includes a housing 21 and a filter screen 24. The housing 21 is provided with an inlet and an outlet. The filter screen 24 covers the inlet.

[0044] The intermediate pipe 4 is inserted into the mounting pipe 11, and the outer port of the intermediate pipe 4 forms a first pair of interfaces 40. Tap water flows into the intermediate pipe 4 through the guide pipe 720 and flows into the filter element 2 for filtration. The filtered water is transported to the water outlet flow channel formed between the intermediate pipe 4 and the mounting pipe 11, and finally transported from the second pair of interfaces 10 into the multi-way pipe 710. The intermediate pipe 4 is further provided with a spacing rib 42 to form the water outlet flow channel between the intermediate pipe 4 and the mounting pipe 11.

[0045] In addition, since the filter element 2 is installed between the connecting body 1 and the filter bottle 3, in order to meet the requirement of cleaning the filter screen 24 on the filter element 2 regularly, the filter further comprises a cleaning component 6 provided with a first water flow driving part 61 and a first cleaning part 62.

[0046] The cleaning component 6 is rotatably sleeved on the shell 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 shell 21. The first cleaning part 62 is configured to rotate with the cleaning component 6 to scrape the filter screen 24 on the shell 21.

[0047] Correspondingly, in order to meet the requirement of discharging the sewage formed by cleaning the filter element 2 by the cleaning component 6 in time, the connecting body 1 is further provided with a sewage discharge connecting pipe 12 in communication with the internal space of the filter bottle 3.

[0048] Specifically, in actual use, when the filter is in normal filtering use, water enters the connecting body 1 through the intermediate pipe 4 and flows into the filter bottle 3. The water is filtered by the filter screen on the shell 21 in the filter bottle 3, flows into the shell 21 through the inlet on the shell 21, and is finally output from the outlet of the shell 21. The water output from the outlet of the filter element 2 enters the mounting pipe 11 and is output into the water heater for use.

[0049] After a long time of use, the surface of the filter screen is covered with dirt such as silt filtered out, which will cause the filtering capacity of the filter screen to decrease and thus the filtering efficiency to decrease. At this time, the sewage discharge connecting pipe 12 can be opened to clean the filter screen of the filter element 2 by the cleaning component 6.

[0050] Specifically, first open the drain connection pipe 12, the water introduced by the intermediate pipe 4 can be discharged from the filter bottle 3 through the drain connection pipe 12. During the water flow in the filter, the water flow acts on the first water flow driving part 61 of the cleaning part 6, so that the first water flow driving part 61 drives the cleaning part 6 to rotate, so that the first cleaning part 62 on the rotating cleaning part 6 can scrape the filter screen of the filter core 2 to clean the dirt on the surface of the filter screen, thereby restoring the filtering capacity of the filter screen, ensuring that the filter can maintain high filtering capacity for a long time, thereby prolonging the overall service life of the filter.

[0051] Wherein, when the drain connection pipe 12 is in an open state, the water introduced from the intermediate pipe 4 enters the connection body 1, 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 shell 21 to clean the filter screen 24 by the first cleaning part 62, and the water flowing into the filter bottle 3 flows into the drain connection pipe 12 through the surface of the shell 21 and is discharged.

[0052] Specifically, in use, when the drain connection 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 drain connection pipe 12 inside the connection body 1 under the water outlet action of the drain connection pipe 12.

[0053] By configuring the cleaning part 6 on the filter core 2, the first water flow driving part 61 and the first cleaning part 62 are configured on the cleaning part 6, the first water flow driving part 61 can use the water flow in the filter to drive the cleaning part 6 to rotate on the filter core 2, so that when the surface of the filter core 2 in the filter needs to be cleaned, the drain connection pipe 12 is opened, and the water flow into the filter is used to drive the cleaning part 6 to rotate to clean the filter screen 24 of the filter core 2, reduce the filter efficiency caused by the filter screen 24 of the filter core 2 being blocked by dirt, improve the filtering efficiency of the filter and prolong the service life.

[0054] In an embodiment, in order to ensure that the cleaning part 6 can reliably rotate on the shell 21 of the filter core 2, one end of the cleaning part 6 is provided with a first supporting part 63, the first supporting part 63 abuts against the outer surface of the shell 21 and is configured to support the cleaning part 6 to rotate on the shell 21.

[0055] Specifically, the cleaning component is supported on the shell 21 by the first support part 63 to meet the requirement that the cleaning component can rotate on the shell 21. The first support part 63 is installed close to one side of the connecting body 1, and the first support part 63 cooperates with the first cleaning part 62 abutting on the filter screen to meet the requirement that the cleaning component rotates on the shell 21.

[0056] In some embodiments, in order to improve the support reliability of the first support part 63, the first support part 63 is a sleeve structure. The first support part 63 is sleeved on the outside of the shell 21 to support the rotation of the cleaning component.

[0057] In addition, in order to improve the rotational driving force of the cleaning component generated by the water flow, the outer surface of the first support part 63 is provided with a second water flow driving part 64, and the first water flow driving part 61 and the second water flow driving part 64 are arranged along the rotation axis direction of the cleaning component 6. 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 component 6 to rotate. The second water flow driving part 64 is configured to be driven by the water flow flowing towards the blowdown connecting pipe 12 to drive the cleaning component 6 to rotate.

[0058] Specifically, for the water flow flowing inside the filter, it is divided into the water flow flowing into the connecting body 1 from the middle pipe 4 and flowing towards the filter bottle 3, which can act on the first water flow driving part 61.

[0059] At the same time, for the water flow flowing inside the filter, it is also divided into the water flow flowing from the filter bottle 3 to the connecting body 1 and flowing out of the blowdown connecting pipe 12, which can act on the second water flow driving part 64.

[0060] In this way, the first water flow driving part 61 and the second water flow driving part 64 are both driven by the water flow to effectively drive the cleaning component to rotate on the shell 21, so as to effectively drive the first cleaning part 62 to clean the filter screen.

[0061] In some embodiments, the first water flow driving part 61 and the second water flow driving part 64 are respectively a plurality of guide ribs formed in the peripheral direction of the cleaning component 6.

[0062] Specifically, the water flow in the filter acts on the guide ribs, and the guide ribs will generate resistance to the water flow, and the reaction force of the water flow is used to drive the cleaning component to rotate.

[0063] The flow guide ribs are arranged obliquely relative to the rotation axis of the cleaning component 6. The oblique arrangement direction of the flow guide ribs matches the water flow action thereon, so that the flow guide ribs constituting the first water flow driving portion 61 and the second water flow driving portion 64 respectively can exert rotational driving force in the same direction on the cleaning component.

[0064] In another embodiment, the other end of the cleaning component 6 is provided with a second support portion 65 abutting against the outer surface of the shell 21 and configured to cooperate with the first support portion 63 to support the rotation of the cleaning component 6 on the shell 21.

[0065] Specifically, the other end of the cleaning component 6 is further provided with the second support portion 65, and the first support portion 63 and the second support portion 65 cooperate with each other to effectively mount the cleaning component 6 on the shell 21.

[0066] The specific structural form of the second support portion 65 can have multiple ways, for example, the second support portion 65 can also adopt a sleeve structure to be sleeved on the shell 21, or the second support portion 65 is a plurality of support columns 503 abutting against the shell 21.

[0067] In another embodiment, the cleaning component 6 is in a sleeve structure as a whole, and the first cleaning portion 62 is arranged on the inner wall of the cleaning component 6.

[0068] Specifically, in order to enable the cleaning component 6 to clean the shell 21 thoroughly, the cleaning component 6 is in a sleeve structure to be sleeved on the outside of the shell 21, and a plurality of first cleaning portions 62 can be arranged on the inner wall of the cleaning component 6.

[0069] In addition, a second cleaning portion 66 can also be arranged on the outer wall of the cleaning component 6, and the second cleaning portion 66 abuts against the inner bottle wall of the filter bottle 3 to clean the inside of the filter bottle 3 through the second cleaning portion 66.

[0070] 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 component 6, and the first cleaning portion 62 and the second cleaning portion 66 can be supported by flexible materials such as silica gel or rubber, so that the first cleaning portion 62 and the second cleaning portion 66 can tightly adhere to the surface to be cleaned.

[0101] In some embodiments, the inner wall of the annular portion 502 is further provided with a flow guide channel 551, the flow guide channel 551 is communicated with the first water flow interface 55, and the water outlet of the flow guide channel 551 is directed towards the first water flow driving portion 61.

[0102] Specifically, in order to effectively drive the cleaning component 6 to rotate quickly 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, the flow guide channel 551 is arranged on the inner wall of the annular portion 502 to guide the water flow of the first water flow interface 55. The water outlet of the flow guide channel 551 is directed towards the first water flow driving portion 61, and the water output from the water outlet of the flow guide channel 551 will act on the first water flow driving portion 61, thereby ensuring that the first water flow driving portion 61 bears sufficient water pressure to drive the cleaning component 6 to rotate.

[0103] 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 shell 21 and is configured to support the rotation of the cleaning component 6 on the shell 21, and the annular portion 502 is located at the periphery of the first support portion 63.

[0104] The first support portion 63 is a sleeve structure, and the outer surface of the first support portion 63 is provided with a second water flow driving portion 64. 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.

[0107] Specifically, for the flow guide channel 551, the water outlet direction of the flow guide channel 551 is towards the filter bottle 3 to generate water flow impact on the first water flow driving part 61 in the water outlet direction. The water entering the filter bottle 3 can flow between the cleaning part 6 and the filter core 2 and flow back to the third water flow interface 56 of the water distributor 5. During the water flow back to the water distributor 5, the water 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. Then, the water flowing out of the water flow interval flows to the surface of the first supporting part 63 to generate water flow impact on the second water flow driving part 64, thereby better achieving the requirement of driving the cleaning part 6 to rotate by using water flow.

[0108] In some embodiments, the outer wall of the cleaning part 6 is further provided with a second cleaning part 66 abutting against the inner bottle wall of the filter bottle 3.

[0109] In some embodiments, in order to facilitate the user to directly observe the use state of the filter core 2 in the filter bottle 3, so as to replace the filter core 2 in time in the case of poor water quality, the filter bottle 3 is in transparent or translucent structure.

[0110] Specifically, since the filter bottle 3 is made of transparent or translucent material, the user can directly observe the state of the filter core 2 in the filter bottle 3 during use, thereby shortening the replacement period of the filter core 2 in the case of poor water quality.

[0111] The water outlet flow channel 111 is formed in the intermediate pipe 4 to meet the communication requirement of the mounting pipe 11 and the water outlet cavity, so that the overall structure of the connection main body 1 is more compact and small, thereby meeting the design requirement of miniaturization.

[0112] The water distributor 5 arranged in the mounting cavity of the connection main body 1 is used to separate the water outlet cavity and the water inlet cavity in the mounting cavity of the connection main body 1. The protruding annular interval part 51 arranged on the annular part is located on one side of the communication port, thereby separating the water inlet cavity and the water outlet cavity in the mounting cavity of the connection main body 1.

[0114] In 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 is in communication with the water inlet cavity through the flow guide channel 551, and the intermediate pipe 4 cooperates with the plug-in portion 54 to isolate the inner end portion of the intermediate pipe 4 from the water outlet cavity, thereby achieving effective isolation between the water inlet cavity and the water outlet cavity.

[0115] In addition, by configuring the plug-in portion 54 on the ring-shaped portion, the installation pipe 11 can better meet the flow requirements of the water outlet flow by using the internal flow channel of the intermediate pipe 4, and at the same time, the inner end portion of the intermediate pipe 4 can be effectively communicated with the water inlet cavity and isolated from the water outlet cavity during the overall assembly process of the filter, thereby facilitating the quick and accurate assembly of the filter.

[0116] In order to further increase the space of the water inlet pipe opening of the installation pipe 11, a recess structure 41 can also be provided on the intermediate pipe 4. The recess structure 41 is arranged opposite to the water inlet pipe opening of the installation pipe 11, so that the water received by the water outlet flow channel 111 can flow more smoothly into the installation pipe 11 at the recess structure 41, thereby ensuring the smooth flow of the water outlet flow.
