[0025] like Figure 1-Figure 10 As shown, an embodiment of the present application provides a water treatment module, including: A valve body 1, wherein a water inlet connecting pipe 11 and a water outlet connecting pipe 12 are arranged on the valve body 1, a through installation cavity is formed in the valve body 1, one end of the installation cavity forms a connecting port 13, and the other end of the installation cavity forms a disassembly port 14, the disassembly port 14 and the connecting port 13 are both formed with internal threads, the connecting port 13 and the disassembly port 14 are arranged in back to back, and the water inlet connecting pipe 11 and the water outlet connecting pipe 12 are respectively connected to the installation cavity; The filter element 2 comprises a housing 21, a core 22, a filter mesh sleeve 24 and a sealing plug 25. An inlet 201 is provided at one end of the housing 21, and an outlet 202 is provided at the other end of the housing 21. The core 22 is located in the housing 21. The filter mesh sleeve 24 is sleeved on the outside of the housing 21 and covers the inlet 201. The sealing plug 25 is provided with an external thread, and the housing 21 is detachably arranged on the sealing plug 25. Filter bottle 3; Among them, the filter bottle 3 is threadedly connected to the connecting port 13, the shell 21 is inserted into the installation cavity through the disassembly and assembly port 14 and extends into the filter bottle 3, and the sealing plug 25 is threadedly connected to the disassembly and assembly port 14; the water inlet connecting pipe 11 is connected to the inlet 201, and the water outlet connecting pipe 12 is connected to the outlet 202.

[0026] Specifically, the two ends of the valve body 1 are open structures, and the filter element 2 is inserted into the installation cavity through the disassembly port 14 and extends into the filter bottle 3. The filter bottle 3 is threadedly connected to the connection port 13, and the filter element 2 is threadedly connected to the disassembly port 14 through the sealing plug 25, so that the filter element 2 and the filter bottle 3 are sealed and connected to the valve body 1.

[0027] During use, when the filter element 2 needs to be removed for maintenance or replacement, the filter element 2 can be removed from the valve body 1 through the disassembly port 14 without the need to additionally disassemble the filter bottle 3. In this way, the disassembly process can be effectively simplified to improve the efficiency of disassembly and maintenance, thereby improving user convenience.

[0028] By providing the valve body 1 with a through installation cavity, the two ends of the installation cavity form a connecting port 13 and a disassembly port 14 which are arranged back to back, and the filter bottle 3 is threadedly connected to the connecting port 13 to achieve a sealed assembly. Similarly, the filter element 2 is threadedly connected to the disassembly port 14 through a sealing plug 25 to achieve a sealed assembly. During later maintenance, the filter element 2 can be removed separately from the disassembly port 14, so that the filter element 2 can be disassembled without disassembling the filter bottle 3, which facilitates disassembly and maintenance to improve ease of use.

[0029] In one embodiment of the present application, the end of the shell 21 having the outlet 202 is provided with a first connecting portion 211 , and the sealing plug 25 is provided with a second connecting portion 251 , and the first connecting portion 211 is clamped on the connecting portion.

[0030] Specifically, after long-term use, the filter material in the housing 21 is easily clogged by scale and becomes ineffective. In order to reduce maintenance costs, the housing 21 and the sealing plug 25 are connected by a structure that is easy to disassemble and assemble.

[0031] A first connection portion 211 is disposed on the end of the shell 21 provided with the outlet 202 , and a second connection portion 251 is disposed on the sealing plug 25 . The first connection portion 211 and the second connection portion 251 are detachably connected together.

[0032] When the filter element 2 needs to be assembled, the housing 21 and the sealing plug 25 are assembled together by using the first connection part 211 and the second connection part 251 to cooperate with each other. After the filter element 2 is removed from the valve body 1, the housing 21 can be separated from the sealing plug 25, so that the housing 21 with new filter material can be assembled on the sealing plug 25 and then reinstalled into the valve body 1 for use. The sealing plug 25 can be reused, reducing the number of parts to be replaced, thereby reducing maintenance costs and usage costs.

[0033] The specific connection method of the first connection part 211 and the second connection part 251 may be various methods, for example, the first connection part 211 and the second connection part 251 are threadedly connected together.

[0034] Alternatively, in one embodiment of the present application, the first connection portion 211 is a first clamping groove formed on the housing 21 , and the second connection portion 251 is a first clamping claw formed on the sealing plug 25 ; Alternatively, the first connection portion 211 is a second claw formed on the housing 21 , and the second connection portion 251 is a second groove formed on the sealing plug 25 .

[0035] Specifically, when the housing 21 needs to be disassembled, the user only needs to press the elastic claws on both sides to disengage the slots to separate the housing 21 from the sealing plug 25. The first connecting portion 211 and the second connecting portion 251 are assembled in a card-mounted manner, making the assembly and disassembly process faster and more convenient, thereby improving the convenience of use.

[0036] In one embodiment of the present application, in order to improve the assembly accuracy between the shell 21 and the sealing plug 25, a positioning portion is provided on the shell 21, and a positioning matching portion is provided on the sealing plug 25, and the positioning portion and the positioning matching portion are connected together.

[0037] Specifically, in the process of assembling and connecting the housing 21 and the sealing plug 25 together, the positioning portion and the positioning matching portion cooperate with each other to provide assembly accuracy and efficiency.

[0038] In one embodiment, the positioning portion is a first positioning slot formed on the shell 21, and the positioning matching portion is a first positioning rib formed on the sealing plug 25, and the first positioning rib is inserted into the first positioning slot; or, the positioning portion is a second positioning rib formed on the shell 21, and the positioning matching portion is a second positioning slot formed on the sealing plug 25, and the second positioning rib is inserted into the second positioning slot.

[0039] For example, it is taken that the housing 21 is provided with a positioning slot 212 , and the sealing plug 25 is provided with a positioning rib 252 .

[0040] During the assembly process, the positioning rib 252 and the positioning slot 212 cooperate and guide each other, so that the first connecting portion 211 and the second connecting portion 251 can be more accurately matched and connected.

[0041] In one embodiment of the present application, a three-way structure 10 is provided on the side wall of the valve body 1, and two ends of the three-way structure 10 located outside the valve body 1 respectively form a water inlet connecting pipe 11 and a water outlet connecting pipe 12; The water treatment module also includes: A water divider 5, the water divider 5 is annular in structure, and an annular spacer 51 is provided on the outer circumference of the water divider 5. The outer circumference of the water divider 5 forms a first water flow area 52 on one side of the annular spacer 51, and the outer circumference of the water divider 5 forms a second water flow area 53 on the other side of the annular spacer 51; Intermediate pipe 4; The intermediate tube 4 is inserted into the water inlet connecting tube 11, the outer end of the intermediate tube 4 is sealed and connected to the inner tube wall of the water inlet connecting tube 11, the inner end of the intermediate tube 4 extends into the interior of the valve body 1, and an auxiliary flow channel 111 is formed between the outer tube wall of the intermediate tube 4 and the inner tube wall of the water inlet connecting tube 11; In addition, the water divider 5 is arranged in the installation cavity, and a water inlet cavity is formed between the first water flow area 52, the installation cavity, the filter element 2 and the filter bottle 3, and a water outlet cavity is formed between the second water flow area 53 and the installation cavity, and the water inlet cavity and the water outlet cavity are separated by the annular spacer 51; the water inlet connecting pipe 11 is connected to the water inlet cavity through the intermediate pipe 4, and the water outlet connecting pipe 12 is connected to the water outlet cavity through the auxiliary flow channel 111.

[0042] Specifically, in order to meet the requirements of water inlet and outlet inside the valve body 1 and meet the requirements of compact and miniaturized installation design, a three-way structure 10 is formed on the side wall of the valve body 1, and one end of the three-way structure 10 is formed on the side wall of the valve body 1, and the remaining two exposed ends respectively form the water inlet connecting pipe 11 and the water outlet connecting pipe 12, and the water inlet connecting pipe 11 and the water outlet connecting pipe 12 are arranged crosswise.

[0043] Among them, the intermediate tube 4 is arranged in the water inlet connecting tube 11, the outer end of the intermediate tube 4 is sealed and connected to the inner tube wall of the water inlet connecting tube 11, the water inlet of the water inlet connecting tube 11 is connected to the intermediate tube 4, and the inner end of the intermediate tube 4 extends into the installation cavity; an auxiliary flow channel 111 is formed between the outer tube wall of the intermediate tube 4 and the inner tube wall of the water inlet connecting tube 11, the water outlet connecting tube 12 is connected to the outlet of the filter element 2 through the auxiliary flow channel 111, and the inner tube mouth of the intermediate tube 4 is connected to the inlet of the filter element 2.

[0044] The water inlet connecting pipe 11 and the water outlet connecting pipe 12 on the valve body 1 must meet the requirements of water inlet and outlet, and 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 three-way structure 10 formed by the valve body 1 enables the auxiliary flow channel 111 and the water outlet connecting pipe 12 to communicate with each other.

[0045] The auxiliary flow channel 111 is formed in the water inlet connecting pipe 11 by using the intermediate pipe 4 to meet the connection requirement between 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 miniaturized design requirements.

[0046] Specifically, the water divider 5 arranged in the installation cavity of the valve body 1 is used to realize the separation of the water outlet cavity and the water inlet cavity formed in the installation cavity of the valve body 1. To this end, after the water divider 5 is installed in the installation cavity of the valve body 1, the annular spacer 51 is located on one side of the connecting port 112, so that the water inlet cavity and the water outlet cavity are separated in the installation cavity of the valve body 1.

[0047] In order to meet the requirement that the water inlet cavity and the water outlet cavity are connected to the water inlet connecting pipe 11 and the water outlet connecting pipe 12 respectively, a first water flow area 52 and a second water flow area 53 are formed on both sides of the annular spacer 51 respectively.

[0048] The water flowing from the water inlet connecting pipe 11 through the intermediate pipe 4 into the installation cavity of the valve body 1 flows through the first water flow area 52 and then enters the filter bottle 3 and the filter element 2 for filtering.

[0049] The water filtered by the filter element 2 flows from the second flow area to the communication port 112 , and flows from the outer wall of the intermediate pipe 4 into the water outlet connecting pipe 12 through the auxiliary flow channel 111 .

[0050] In one embodiment of the present application, the annular spacer 51 is provided with a plug-in portion 54, the plug-in portion 54 is located in the second water flow area 53, the plug-in portion 54 is provided with a plug-in port 55, and the side of the plug-in port 55 is provided with a through hole 56 of the annular spacer 51 that penetrates the annular spacer 51; The inner end of the intermediate tube 4 is sealed and inserted into the insertion port 55 , and the inner tube opening of the intermediate tube 4 is connected to the first water flow area 52 through the through opening 56 .

[0051] Specifically, since both the inlet and outlet water need to enter and exit through the connecting port 112 on the valve body 1, in order to separate the inlet and outlet water flows, a plug-in portion 54 is provided on the annular spacer 51, and the plug-in port 55 formed on the plug-in portion 54 is used to connect the pipe opening of the inner end portion of the intermediate pipe 4, and the through-port 56 provided on the side of the plug-in port 55 can penetrate the annular spacer 51, thereby allowing the second water flow area 53 to communicate with the plug-in port 55 through the through-port 56.

[0052] During the assembly process, the inner end of the intermediate tube 4 is inserted into the plug-in port 55 so that the intermediate tube 4 is connected to the second water flow area 53 through the through-port 56, and the intermediate tube 4 and the plug-in port 54 cooperate with each other so that the inner end of the intermediate tube 4 can be isolated from the first water flow area 52, thereby meeting the effective isolation between the water inlet cavity and the water outlet cavity.

[0053] In addition, by configuring the plug-in portion 54 on the annular spacer portion 51, the flow requirement of the outlet water flow can be better met by the water outlet connecting pipe 12 using the internal flow channel of the water inlet connecting pipe 11. At the same time, it is also convenient for the overall assembly process of the water treatment module, and the inner end of the intermediate tube 4 can be effectively connected to the water inlet cavity while being effectively isolated from the water outlet cavity, thereby facilitating the rapid and accurate assembly of the water treatment module.

[0054] In another embodiment, for the water outlet cavity, since the end of the filter element 2 having the outlet 202 is inserted in the water divider 5, in order to allow the water output from the filter element 2 to smoothly enter the water outlet cavity, a through hole 57 can be further provided on the water divider 5, and the through hole 57 is located in the second water flow area 53.

[0055] Specifically, the filtered water output from the outlet 202 of the filter element 2 will flow into the area formed by the water divider 5 and through the through-hole 57, so that the water in the water divider 5 flows into the second water flow area 53 formed on its outer wall. The water is guided through the second water flow area 53 and flows into the auxiliary flow channel 111 through the connecting port 112.

[0056] The through opening 57 may be located at any position on one side of the plug-in portion 54 , for example, the through opening 57 and the plug-in port 55 are arranged in opposite directions.

[0057] In another embodiment, a flange structure 58 is further provided on the edge of the annular spacer 51 , and the flange structure 58 extends away from the second water flow area 53 . A first annular water groove is formed between the flange structure 58 and the water divider 5 , and the first annular water groove forms the first water flow area 52 .

[0058] Specifically, since the water inlet cavity and the water outlet cavity are separated in the installation cavity of the valve body 1 by the annular spacer 51, the water flowing into the first annular water groove through the through-hole 56 of the intermediate tube 4 can be guided by the first annular water groove and distributed more evenly on the periphery of the filter element 2, thereby ensuring that the water can be filtered more effectively.

[0059] In another embodiment, the second water flow area 53 is a second annular water groove formed on the outer periphery of the water divider 5, and first sealing rings are respectively arranged on both sides of the second annular water groove, wherein one of the first sealing rings is squeezed between the outer wall of the water divider 5 and the inner wall of the installation cavity, and the other first sealing ring is squeezed between the annular spacer 51 and the inner wall of the installation cavity.

[0060] Specifically, the second water flow area 53 is a second annular water groove formed in a depression on the surface layer of the outer wall of the water divider 5 , and the second annular water groove can guide the water flow to flow more smoothly.

[0061] In one embodiment of the present application, a first sealing ring is provided on the outer circumference of the annular spacer 51, and the first sealing ring is squeezed between the inner wall of the valve body 1 and the annular spacer 51; The housing 21 is provided with a second sealing ring, the second sealing ring is close to the outlet 202 , and the second sealing ring is squeezed between the housing 21 and the inner wall of the water separator 5 .

[0062] Specifically, a water outlet cavity is formed between the first sealing ring and the sealing plug 25 in the installation cavity of the valve body 1, and the first sealing ring can isolate the water inlet cavity from the water outlet cavity.

[0063] In one embodiment of the present application, an annular protrusion structure 42 is formed on the outer tube wall of the outer end of the intermediate tube 4, and a sealing ring is arranged between the annular protrusion structure 42 and the inner tube wall of the water inlet connecting pipe 11; a plurality of spaced support ribs 43 are arranged on the outer tube wall of the intermediate tube 4, and the support ribs 43 are against the inner tube wall of the water inlet connecting pipe 11.

[0064] In some embodiments of the present application, in order to facilitate the reliable sealing assembly of the intermediate tube into the water inlet connecting pipe, such as Figure 8 As shown, an annular protrusion structure 42 is formed on the outer tube wall of the outer end of the intermediate tube, and a sealing ring (not shown) is arranged between the annular protrusion structure and the inner tube wall of the water inlet connecting pipe.

[0065] Specifically, since the intermediate tube 4 is inserted into the water inlet connecting tube 11 and forms the auxiliary flow channel 111, and at the same time, the intermediate tube 4 also needs to be sealed and connected to the water inlet connecting tube 11, an annular protrusion structure 42 is formed at the outer end of the intermediate tube 4 to fit tightly against the inner tube wall of the water inlet connecting tube 11, and the annular protrusion structure 42 is further sealed and connected to the water inlet connecting tube 11 through a sealing ring.

[0066] In this way, the water introduced by the water inlet connecting pipe 11 will enter the intermediate pipe 4 for transportation and will not leak into the auxiliary flow channel 111 .

[0067] In another embodiment, a plurality of spaced-apart support ribs 43 are provided on the outer tube wall of the intermediate tube, and the support ribs are against the inner tube wall of the water inlet connecting pipe.

[0068] Specifically, after the front end of the intermediate tube 4 is assembled in the water inlet connecting tube 11 through the annular protrusion structure 42, the support rib 43 will also abut against the water inlet connecting tube 11. In this way, the intermediate tube 4 is firmly and stably assembled in the water inlet connecting tube 11 by utilizing the annular protrusion structure 42 and the support rib 43.

[0069] In one embodiment, a positioning support ring 113 is provided on the inner tube wall of the water inlet connecting pipe 11, and the supporting ribs abut against the positioning support ring.

[0070] Specifically, the positioning support ring 113 provided on the inner tube wall of the water inlet connecting pipe 11 is used to cooperate with the support rib 43 to support the support rib 43. In addition, the positioning support ring 113 cooperates with the support rib 43 to start positioning the installation position of the intermediate pipe 4 in the water inlet connecting pipe 11, so as to facilitate the assembly of the operator.

[0071] In another embodiment, in order to facilitate assembly and avoid transportation during assembly, Fig. 9 As shown, the intermediate tube 4 falls off from the water inlet connecting tube 11, and at least one elastic stopper 44 is provided on the outer tube wall of the inner end of the intermediate tube, wherein the first end of the elastic stopper is provided on the intermediate tube, and the second end of the elastic stopper extends obliquely toward the outer end of the intermediate tube and away from the outer tube wall of the intermediate tube; The first end and the second end of the elastic limiting member 44 are arranged in opposite directions, and the second end of the elastic limiting member is clamped on the positioning support ring.

[0072] Specifically, during the assembly process, the middle tube 4 is inserted into the water inlet connecting tube 11 from the water inlet connecting tube 11, and after the elastic stopper 44 moves to the positioning support ring 113 and is squeezed, the elastic stopper 44 is deformed to pass over the positioning support ring 113. After the middle tube 4 is assembled in place, the elastic stopper 44 is reset due to its own elasticity, and the second end of the elastic stopper 44 is stuck on the inner side of the positioning support ring 113.

[0073] The elastic limiting member 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.

[0074] In another embodiment of the present application, since the filter element 2 needs to be replaced regularly, in order to improve the overall 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 components, the following structural design and improvement are performed on the water treatment module.

[0075] In another embodiment of the present application, in order to ensure that the water flow in the auxiliary flow channel 111 can flow smoothly, it is necessary to increase the water flow cross-sectional area of ​​the auxiliary flow channel 111. To this end, the intermediate pipe 4 is improved as follows. Fig.10 As shown, the intermediate tube 4 is an eccentric tube, the outer end of the eccentric tube is sealed and connected to the inner tube wall of the water inlet connecting tube 11, the inner end of the eccentric tube is inserted into the plug port 55, and the plug port 55 and the connecting port 112 are eccentrically arranged relative to each other.

[0076] Specifically, the intermediate tube 4 adopts the structure of an eccentric tube, and the outer end of the eccentric tube can be well sealed and connected to the water inlet connecting tube 11, so that all the water entering the water inlet connecting tube 11 can flow into the eccentric tube. The inner end of the eccentric tube extends into the connecting port 112, and the pipe opening of the inner end of the eccentric tube and the pipe opening of the outer end thereof form an eccentric arrangement. At the same time, the pipe opening of the inner end of the eccentric tube is also offset in the connecting port 112, so that an auxiliary flow channel 111 with a larger cross section can be formed between the eccentric tube and the water inlet connecting tube 11, thereby satisfying that the water in the water outlet cavity flows smoothly into the water outlet connecting tube 12 via the auxiliary flow channel 111.

[0077] In order to further increase the space at the water inlet of the water outlet connecting pipe 12, a recessed structure 41 may be provided on the intermediate pipe 4. The recessed structure 41 is arranged opposite to the water inlet of the water outlet connecting pipe 12, so that the water transported by the auxiliary flow channel 111 can flow more smoothly into the water outlet connecting pipe 12 at the recessed structure 41, thereby ensuring smooth flow of the outlet water flow.

[0078] In order to facilitate the user to drive the sealing plug 25 to rotate, a decorative cap 26 may be provided on the outside of the sealing plug 25. The decorative cap 26 may be mounted on the sealing plug 25 and arranged on the outside of the sealing plug 25 to make the overall appearance more beautiful. The outer circumference of the decorative cap 26 may be provided with a plurality of ribs or grooves to increase friction and facilitate the user to rotate the decorative cap 26 by hand.

[0079] 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 ensure 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.

[0080] Specifically, the valve body 1 is made of metal materials, such as stainless steel, copper and other metal materials used for water supply. The two ends corresponding to the three-way structure 10 on the valve body 1 form a water inlet connecting pipe 11 and a water outlet connecting pipe 12, which are also made of metal materials. When connected to 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 a sufficiently strong structural strength to ensure the connection reliability of the connection parts.

[0081] Furthermore, for the filter assembly, the filter bottle 3 is installed on the connecting port 13, and the filter element 2 is installed on the disassembly port 14, so as to meet the assembly requirements of the filter assembly.

[0082] During later use, the filter assembly can be disassembled from the valve body 1 without causing damage to the structure of the valve body 1, thereby improving the reliability of use.

[0083] Among them, the filter bottle 3 is 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 external thread, so as to increase the structural strength of the filter bottle 3 near the external thread through the structural reinforcement part, thereby improving the reliability of the filter bottle 3.

[0084] In some embodiments, the structural reinforcement portion is a thickened layer formed near the external thread of the filter bottle 3. Specifically, during the injection molding process, the filter bottle 3 can form a thickened layer on the inner side of the outer wall where the external thread is formed, and the thickened layer is used to improve the structural strength of the filter bottle 3 at the bottle mouth.

[0085] Alternatively, in some embodiments, the structural reinforcement portion 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 at the bottle mouth of the filter bottle 3 on the one hand, and on the other hand, the user can use a disassembly tool to clamp on the disassembly rib 31 during disassembly to drive the filter bottle 3 to rotate.

[0086] In another embodiment, in order to facilitate the user to visually see the usage status of the filter element 2 in the filter bottle 3 and to replace the filter element 2 in time when the water quality is poor, the filter bottle 3 is a transparent structure or a translucent structure.

[0087] 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, thereby shortening the replacement cycle of the filter element 2 when the water quality condition is poor.

[0088] In another embodiment, in order to further enrich the functions of the filter element 2, a mounting groove is provided on the end surface of the second end of the shell 21, and a permanent magnet 23 is provided in the mounting groove.

[0089] Specifically, by providing a mounting groove at the second end of the housing 21, the permanent magnet 23 can be installed in the mounting groove. For the water flowing through, the water flowing through can be magnetized under the action of the permanent magnet 23. The permanent magnet 23 increases the dissolved oxygen content of the water, promotes the activity of microorganisms in the water, reduces the formation of scale, and improves the quality of the incoming water.

[0090] The present application also provides a water heater, including a water heater body, on which a water inlet pipe and a water outlet pipe are arranged, and also includes the above-mentioned water treatment module, wherein the water outlet connecting pipe of the water treatment module is connected to the water inlet pipe.
