[0077] The water distributor 5 is in an annular structure, and an annular spacing part 51 is arranged on the outer periphery of the water distributor 5. The outer periphery of the water distributor 5 is formed with a first water flow area 52 on one side of the annular spacing part 51, and is formed with a second water flow area 53 on the other side of the annular spacing part 51.

[0078] The intermediate pipe 4;

[0079] The intermediate pipe 4 is inserted into the water inlet connecting pipe 11, the outer end of the intermediate pipe 4 is sealingly connected with the inner pipe wall of the water inlet connecting pipe 11, the inner end of the intermediate pipe 4 extends into the interior of the valve body 1, and the outer pipe wall of the intermediate pipe 4 and the inner pipe wall of the water inlet connecting pipe 11 form an auxiliary flow channel 111.

The three-way structure 10 formed by the valve body 1 enables the auxiliary flow channel 111 and the water outlet connecting pipe 12 to be communicated with each other.

[0084] The auxiliary flow channel 111 formed by the intermediate pipe 4 in the water inlet connecting pipe 11 meets the communication requirement of the water outlet connecting pipe 12 and the water outlet cavity, so that the overall structure of the valve body 1 is more compact and small, thereby meeting the design requirement of miniaturization.

[0085] Specifically, the water distributor 5 arranged in the mounting cavity of the valve body 1 is used to realize the separation of the water outlet cavity and the water inlet cavity in the mounting cavity of the valve body 1.

[0105] In some embodiments of the present application, in order to facilitate the reliable sealing and assembly of the intermediate pipe into the water inlet connecting pipe, as shown in Figure 8 An annular protruding structure 42 is formed on the outer tube wall of the outer end portion of the intermediate pipe, and a sealing ring (not shown) is arranged between the annular protruding structure and the inner tube wall of the water inlet connecting pipe.

[0106] Specifically, since the intermediate pipe 4 is inserted into the water inlet connecting pipe 11 and forms the auxiliary flow channel 111, and meanwhile, the intermediate pipe 4 needs to be sealingly connected with the water inlet connecting pipe 11, the annular protruding structure 42 is formed on the outer end of the intermediate pipe 4 to tightly adhere to the inner pipe wall of the water inlet connecting pipe 11, and the annular protruding structure 42 is further sealingly connected with the water inlet connecting pipe 11 through a sealing ring.

[0107] In this way, the water introduced by the water inlet connecting pipe 11 will enter the intermediate pipe 4 for delivery without leaking into the auxiliary flow channel 111.

[0108] In another embodiment, a plurality of support ribs 43 are arranged on the outer pipe wall of the intermediate pipe, and the support ribs abut against the inner pipe wall of the water inlet connecting pipe.

[0109] Specifically, after the front end of the intermediate pipe 4 is assembled into the water inlet connecting pipe 11 through the annular protruding structure 42, the support ribs 43 will also abut against the water inlet connecting pipe 11, so that the intermediate pipe 4 is firmly and stably assembled into the water inlet connecting pipe 11 by the annular protruding structure 42 and the support ribs 43.

[0110] In an embodiment, a positioning support ring 113 is arranged on the inner pipe wall of the water inlet connecting pipe 11, and the support ribs abut against the positioning support ring.

[0111] Specifically, the positioning support ring 113 arranged on the inner pipe wall of the water inlet connecting pipe 11 is used to cooperate with the support ribs 43 to support the support ribs 43. Moreover, the cooperation of the positioning support ring 113 and the support ribs 43 can also start the installation position of the intermediate pipe 4 in the water inlet connecting pipe 11 to facilitate the assembly of the operator.

[0112] In another embodiment, in order to facilitate assembly and avoid the intermediate pipe 4 from falling off the water inlet connecting pipe 11 during transportation and assembly, as shown in Figure 9 the intermediate pipe 4, at least one elastic limiting member 44 is arranged on the outer pipe wall of the inner end of the intermediate pipe, a first end of the elastic limiting member is arranged on the intermediate pipe, and a second end of the elastic limiting member extends obliquely towards the outer end of the intermediate pipe and away from the outer pipe wall of the intermediate pipe.

[0113] The first end and the second end of the elastic limiting member 44 are arranged oppositely, and the second end of the elastic limiting member is clamped on the positioning support ring.

[0114] Specifically, during the assembly process, the intermediate pipe 4 is inserted into the water inlet connecting pipe 11 from the water inlet connecting pipe 11 part, and after the elastic limiting part 44 is extruded at the positioning support ring 113, the elastic limiting part 44 is deformed to pass the positioning support ring 113. After the intermediate pipe 4 is assembled in place, the elastic limiting part 44 is reset due to its own elasticity, and the second end of the elastic limiting part 44 is clamped on the inner side of the positioning support ring 113.

[0115] The elastic limiting part 44 cooperates with the positioning support ring 113 to limit the intermediate pipe 4 from being separated from the water inlet connecting pipe 11, thereby improving the reliability during transportation and on-site installation.

[0116] In another embodiment of the present application, since the filter element 2 needs to be replaced regularly, in order to improve the overall use reliability of the water treatment module and reduce damage to the overall structure of the water treatment module caused by frequent disassembly and assembly of the filter assembly, the water treatment module is designed and improved as follows.

[0117] In another embodiment of the present application, in order to ensure smooth flow of water in the auxiliary flow passage 111, it is necessary to increase the water flow cross-sectional area of the auxiliary flow passage 111. To this end, the intermediate pipe 4 is improved in structure as follows. Figure 10 As shown in the figure, the intermediate pipe 4 is an eccentric pipe, the outer end of the eccentric pipe is sealingly connected to the inner pipe wall of the water inlet connecting pipe 11, the inner end of the eccentric pipe is inserted into the insertion port 55, and the insertion port 55 and the communication port 112 are eccentrically arranged with respect to each other.

[0118] Specifically, the intermediate pipe 4 adopts an eccentric pipe structure, the outer end of the eccentric pipe can be sealingly connected to the water inlet connecting pipe 11 to ensure that all the water entering the water inlet connecting pipe 11 can flow into the eccentric pipe. The inner end of the eccentric pipe extends into the communication port 112, the pipe opening of the inner end of the eccentric pipe is eccentrically arranged with respect to the pipe opening of the outer end, and the pipe opening of the inner end of the eccentric pipe is also offset in the communication port 112. In this way, the auxiliary flow passage 111 with a large cross section can be formed between the eccentric pipe and the water inlet connecting pipe 11, thereby ensuring smooth flow of water from the water outlet connecting pipe 12 into the water outlet connecting pipe 12.

[0119] In order to further increase the space at the water inlet pipe opening of the water outlet connecting pipe 12, 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 water outlet connecting pipe 12, so that the water transported by the auxiliary flow passage 111 can flow more smoothly into the water outlet connecting pipe 12 at the recess structure 41, thereby ensuring smooth flow of the outlet water.

[0120] In order to facilitate the user to drive the sealing plug 25 to rotate, the sealing plug 25 can be additionally provided with a decorative cap 26. The decorative cap 26 can be clamped on the sealing plug 25 and arranged on the outer side of the sealing plug 25 to make the overall appearance more beautiful. The outer periphery of the decorative cap 26 can be provided with a plurality of ribs or grooves to increase the friction force and facilitate the user to rotate the decorative cap 26 by hand.

[0121] Since the valve body 1 needs to meet the installation requirements of the water inlet pipe 200 and the filter assembly, and also needs to meet the requirement that the overall structure of the valve body 1 will not be damaged during the frequent disassembly and assembly of the filter assembly, the valve body 1 is made of metal material.

[0122] Specifically, the valve body 1 is made of metal material, for example, stainless steel, copper and other metal materials used for water supply. The two ends of the three-way structure 10 on the valve body 1 form a water inlet connecting pipe 11 and a water outlet connecting pipe 12. The water inlet connecting pipe 11 and the water outlet connecting pipe 12 are also made of metal material. When connected with the water inlet pipe 200 of the water heater and the water supply pipe in the user's home, the water inlet connecting pipe 11 and the water outlet connecting pipe 12 have sufficient structural strength to ensure the connection firmness and reliability of the connection part.

[0123] In addition, for the filter assembly, the filter bottle 3 is installed on the connecting port 13, and the filter core 2 is installed on the disassembly port 14 to meet the assembly requirements of the filter assembly.

[0124] During the later use, the disassembly and assembly of the filter assembly from the valve body 1 will not cause damage to the structure of the valve body 1, thereby improving the use reliability.

[0125] Among them, for the filter bottle 3, generally made of plastic material, in order to improve its structural strength, the outer wall of the filter bottle 3 is provided with a structural reinforcement part near the outer thread, so as to increase the structural strength of the filter bottle 3 near the outer thread part, thereby improving the use reliability of the filter bottle 3.

[0126] In some embodiments, the structural reinforcement part is a thickening layer formed near the outer thread of the filter bottle 3. Specifically, during the injection molding process of the filter bottle 3, a thickening layer can be formed on the inner side of the outer wall of the filter bottle 3 where the outer thread is formed, so as to improve the structural strength of the filter bottle 3 at the bottle opening position.

[0127] Alternatively, in some embodiments, the structural reinforcement part is a disassembly rib 31 provided on the outer wall of the filter bottle 3. Specifically, the disassembly rib 31 formed on the outer wall of the filter bottle 3 can improve the structural strength of the filter bottle 3 at the bottle opening position on the one hand, and on the other hand, the user can clamp the disassembly rib 31 with a disassembly tool during disassembly to drive the filter bottle 3 to rotate.

[0128] In another embodiment, in order to allow the user to directly observe the use state of the filter element 2 in the filter bottle 3, and to replace the filter element 2 in time in the case of poor water quality, the filter bottle 3 is transparent or translucent.

[0129] Specifically, since the filter bottle 3 is made of transparent or translucent material, the user can directly observe the state of the filter element 2 in the filter bottle 3 during use, and thus can shorten the replacement period of the filter element 2 in the case of poor water quality.

[0130] In another embodiment, in order to further enrich the functions of the filter element 2, a mounting groove is arranged on the end face of the second end portion of the shell 21, and a permanent magnet 23 is arranged in the mounting groove.

[0131] Specifically, by arranging the mounting groove on the second end portion of the shell 21, the permanent magnet 23 can be mounted in the mounting groove. For the water flow, under the action of the permanent magnet 23, the water flow can be magnetized. The permanent magnet 23 increases the dissolved oxygen content of the water, promotes the activity of microorganisms in the water, reduces the generation of scale, and improves the quality of the water.

[0132] The application also provides a water heater, which comprises a water heater body, a water inlet pipe and a water outlet pipe arranged on the water heater body, and the water treatment module, wherein the water outlet connecting pipe of the water treatment module is connected with the water inlet pipe.
