[0024] like Figure 1-Figure 2 As shown, this embodiment provides a water heater, which includes a water heater body 100. The water heater body 100 may be an electric water heater, a water tank of a heat pump water heater, or a water tank of a solar water heater.

[0025] When the water heater body 100 is used in a user's home, it is installed on a wall of the user's home according to installation requirements.

[0026] The water heater body 100 is provided with a water inlet pipe 200 and a water outlet pipe 300. In order to improve the water quality of the water heater, a filter 500 can be added between the water inlet pipe 200 of the water heater and the water supply pipe in the user's home to filter the water output from the water supply pipe through the filter 500.

[0027] In addition, the filter 500 generally includes a connecting body 1 and a filter assembly, the filter assembly includes a filter element 2 and a filter bottle 3, the connecting body 1 is used to meet the connection requirements between the water inlet pipe 200 of the water heater and the water supply pipe in the user's home, and at the same time, the connecting body 1 is also used to install the filter element 2 and the filter bottle 3 of the filter assembly.

[0028] Embodiment 1, in order to optimize the appearance of the whole water heater, to avoid the appearance being deteriorated due to the filter 500 being exposed at the bottom of the water heater after the filter 500 is installed.

[0029] The water heater body 100 is further provided with a decorative cover 400, the water inlet pipe 200 and the water outlet pipe 300 are arranged at the back of the decorative cover 400, and is characterized in that it also includes a filter 500; As for the filter 500 , the filter assembly is arranged horizontally as a whole and is hidden at the back of the decorative cover 400 .

[0030] Specifically, the water inlet pipe 200 of the water heater is used to meet the internal water intake, and the water outlet pipe 300 is used to output the heated water to the water terminal. As for the water entering the water inlet pipe 200, the water quality can be filtered through the filter 500 to improve the quality of the water entering the water heater.

[0031] Among them, since the filter 500 is installed on the water inlet pipe 200, in order to realize a hidden installation method of the filter 500, the installation structure of the filter 500 is improved and designed.

[0032] Specifically, the filter element 2 and the filter bottle 3 of the filter 500 are both arranged horizontally, and the space at the bottom of the water heater is used to extend horizontally for installation. In this way, the overall height 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.

[0033] The connection body 1 of the filter 500 is connected to the external water pipe through the water inlet connection pipe 11, and is connected to the water inlet pipe 200 on the water heater body 100 through the water outlet connection pipe 12. The filter element 2 and the filter bottle 3 are installed on the corresponding connection ports of the connection body 1.

[0034] For the filter 500, its specific structural design has various structural forms, which are described below with reference to the accompanying drawings.

[0035] Embodiment 2, as Figure 1-Figure 9 As shown, the filter 500 comprises: A connecting body 1, on which a water inlet connecting pipe 11 and a water outlet connecting pipe 12 are arranged, and an open installation cavity is also arranged on the connecting body 1, and a first connecting port 13 is arranged at the open end of the installation cavity, and a second connecting port 14 is also arranged inside the first connecting port 13 in the installation cavity; The filter element 2 comprises a housing 21 and a core 22. An inlet 201 is disposed at one end of the housing 21, and an outlet 202 is disposed at the other end of the housing 21. The core 22 is disposed in the housing 21 and is configured to filter water input from the inlet 201 and output the water from the outlet 202. Filter bottle 3; The filter bottle 3 and the filter element 2 are arranged transversely, the filter element 2 is arranged on the second connection port 14, the filter bottle 3 covers the outside of the filter element 2 and is connected to the first connection port 13; a water inlet cavity is formed between the filter bottle 3, the shell 21 and the connection body 1, a water outlet cavity is formed between the shell 21 and the inner wall of the connection body 1, the water inlet connecting pipe 11 is connected to the water inlet cavity, and the water outlet connecting pipe 12 and the outlet 202 are respectively connected to the water outlet cavity; In addition, the filter 500 is arranged at the back of the decorative cover 400 , and the water outlet connecting pipe 12 is connected to the water inlet pipe 200 .

[0036] In the actual assembly process, the filter element 2 is first inserted into the installation cavity formed by the connecting body 1 and connected to the second connecting port 14, and then the filter bottle 3 is connected to the first connecting port 13, so that the filter assembly can be completed.

[0037] During the installation process, the connecting body 1 is connected to the external water pipe through the water inlet connecting pipe 11, and is connected to the water inlet pipe 200 of the water heater through the water outlet connecting pipe 12, so as to install the filter 500 between the water inlet pipe 200 and the external water pipe. After the filter 500 is installed, the filter bottle 3 and the filter element 2 are arranged horizontally and are located at the rear side of the decorative cover 400, so that the rear space of the decorative cover 400 can be fully utilized to hide and install the filter 500.

[0038] A first connection port 13 and a second connection port 14 are provided on the connecting body 1 to meet the installation requirements of the filter element 2 and the filter bottle 3. As for the filter element 2 and the filter bottle 3, they are arranged to be extended laterally as a whole. In this way, after the filter 500 is installed on the water inlet pipe 200 of the water heater, the filter element 2 and the filter bottle 3 will utilize the lateral space at the bottom of the water heater for installation, thereby reducing the space occupied by the filter 500 in the height direction. In this way, the filter 500 can be hidden inside the decorative cover 400 of the water heater to optimize the overall appearance and improve the user experience.

[0039] In some embodiments, in order to facilitate the installation of on-site pipelines, the water outlet connecting pipe 12 is arranged vertically and extends upward, and the water inlet connecting pipe 11 is arranged horizontally.

[0040] Specifically, when the water heater is installed in the user's home, the water heater is arranged above the external water pipe provided on the wall of the user's home, and the water inlet pipe 200 of the water heater and the external water pipe on the wall are arranged perpendicular to each other. To this end, the water inlet connection pipe 11 on the connection body 1 is arranged horizontally and extends toward the back of the water heater to meet the requirements of connecting with the external water pipe on the wall. At the same time, the water outlet connection pipe 12 on the connection body 1 is arranged vertically and extends upward to meet the requirements of connecting with the water inlet pipe 200 of the water heater.

[0041] In this way, when the water heater is installed at the user's home, it is more convenient to connect the on-site pipelines to reduce the difficulty of installation.

Similarly, in order to meet the flow requirements of water inlet and water outlet, a third flow channel 161 and a fourth flow channel 162 are formed inside the second connecting member 16.

[0044] During use, the water output from the external water pipe enters the water inlet connecting pipe 11 and flows into the water inlet cavity through the first flow channel 151 and the third flow channel 161. The water in the water inlet cavity enters the interior of the filter element 2 from the inlet 201 of the filter element 2 for further filtering and then enters the water outlet cavity from the outlet 202. The water in the water outlet cavity is output from the water outlet connecting pipe 12 through the fourth flow channel 162 and the second flow channel 152 and enters the water inlet pipe 200 of the water heater.

[0045] In one embodiment, a step surface (not marked) is formed in the installation cavity, and the step surface is located between the port of the third flow channel 161 and the port of the fourth flow channel 162; an annular rib 141 is provided on the step surface, and the annular rib 141 surrounds and forms the second connection port 14.

[0046] Specifically, since the water inlet cavity is connected to the third flow channel 161, and the water outlet cavity is connected to the fourth flow channel 162, in order to effectively isolate the third flow channel 161 and the fourth flow channel 162, a step surface is provided between the third flow channel 161 and the fourth flow channel 162, and an annular rib 141 is formed on the step surface. The filter element 2 is installed through the second connection port 14 formed by the annular rib 141, and the third flow channel 161 and the fourth flow channel 162 are further isolated by the annular rib 141, thereby achieving isolation between the water inlet cavity and the water outlet cavity in the connection body 1.

[0047] In another embodiment, the basic function of the filter element 2 needs to be able to filter the incoming water. To this end, the water flow entering from the inlet 201 of the shell 21 needs to be filtered. Generally, a filter net is provided on the inlet 201.

[0048] Specifically, a filter mesh sleeve 24 is further provided on the outer wall of the housing 21 . The filter mesh sleeve 24 is sleeved on the outside of the housing 21 and covers the inlet 201 .

[0049] After the water entering the filter 500 flows into the water inlet cavity, the water is filtered through the filter mesh sleeve 24 and then enters the interior of the housing 21 through the inlet 201 and flows into the water outlet cavity from the outlet 202. The filter mesh sleeve 24 can effectively filter out the sediment in the water to improve the water quality of the water heater.

Under the action of the flow-blocking ribs 217, the water flow can be evenly distributed on the outer circumference of the cylinder 211.

[0058] In another embodiment, in order to further enrich the functions of the filter element 2 , a mounting groove 219 is provided on the end surface of the second end of the cylinder 211 , and a permanent magnet 23 is provided in the mounting groove 219 .

[0059] Specifically, by providing a mounting groove 219 at the second end of the cylinder 211, the permanent magnet 23 can be installed in the mounting groove 219. 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.

[0060] In one embodiment, the connection ring 213 on the connection cover 212 can be inserted into the annular rib 141 to form the second connection port 14 by means of insertion, and a sealing ring is provided between the connection ring 213 and the annular rib 141 to meet the requirement of sealed connection.

[0061] In some embodiments, since the filter bottle 3 is hidden at the back of the decorative cover 400 , a plurality of disassembly and assembly ribs 31 arranged at intervals may be provided on the outer circumference of the filter bottle 3 to facilitate disassembly by the user.

[0062] Specifically, the open end of the filter bottle 3 can be sealed and fixed in the first connection port 13 by threaded connection. During the disassembly of the filter bottle 3, a tool such as a wrench is clamped on the disassembly rib 31 to rotate the filter bottle 3 with the help of a rotating tool, thereby realizing the disassembly operation of the filter bottle 3.

[0063] In some embodiments, there may be multiple forms for the specific extension of the filter bottle 3 and the filter element 2 in the lateral direction.

[0064] For example: Figure 1 and Figure 2 As shown, the filter bottle 3 and the filter element 2 extend toward the back of the water heater.

[0065] Specifically, refer to Figure 2 It can be seen that the filter bottle 3 and the filter element 2 are arranged laterally on the back of the decorative cover 400 and extend in a direction away from the decorative cover 400 .

[0066] like Figure 3 and Figure 4 As shown, the filter bottle 3 and the filter element 2 extend toward the water outlet pipe 300 and are arranged between the water outlet pipe 300 and the decorative cover 400 .

[0067] Specifically, refer to Figure 2 It can be seen that the filter bottle 3 and the filter element 2 are arranged horizontally on the back of the decorative cover 400 and extend from the water inlet pipe 200 to the water outlet pipe 300. Since the space between the water inlet pipe 200 and the water outlet pipe 300 of the water heater is generally not additionally arranged with related functional components, the filter bottle 3 and the filter element 2 can be arranged and installed using the space between the water inlet pipe 200 and the water outlet pipe 300. The end of the filter bottle 3 with a longer length can also extend over the water outlet pipe 300 and be located between the water outlet pipe 300 and the decorative cover 400.

[0068] Since the filter bottle 3 and the filter element 2 are arranged in the area between the water inlet pipe 200, the water outlet pipe 300 and the decorative cover 400, the space behind the water inlet pipe 200 and the water outlet pipe 300 can be vacated to facilitate the connection of the water pipe.

[0069] Embodiment three, as Figure 10-Figure 21 As shown, the present application also provides a structure of a filter 500 .

[0070] Since the filter element 2 needs to be replaced regularly, in order to improve the overall reliability of the filter 500 and reduce damage to the overall structure of the filter 500 caused by frequent disassembly and assembly of the filter assembly, the following structural design and improvement are performed on the filter 500.

[0071] The filter 500 includes a connection body 1 and a filter assembly. The connection 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 connection body 1 will not be damaged during the frequent disassembly and assembly of the filter assembly. The connection body 1 is made of metal material, and is provided with an inlet connection pipe 11 and an outlet connection pipe 12, and is also provided with a first connection port 13.

[0072] A filter assembly, the filter assembly comprising a filter element 2 and a filter bottle 3, the filter element 2 being disposed in the filter bottle 3, the filter element 2 having an inlet 201 and an outlet 202, the filter element 2 being configured to filter water input from the inlet 201 and output from the outlet 202; The filter bottle 3 is disposed at the first connection port 13 , the water inlet connection pipe 11 is connected to the inlet 201 , and the water outlet connection pipe 12 is connected to the outlet 202 .

[0073] Specifically, the connection body 1 is made of metal materials, such as stainless steel, copper and other metal materials used for water supply. The connection body 1 forms a corresponding water inlet connection pipe 11 and a water outlet connection 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 connection pipe 11 and the water outlet connection pipe 12 have a sufficiently strong structural strength to ensure the connection reliability of the connection part.

[0074] Furthermore, for the filter assembly, the filter bottle 3 is installed on the first connecting port 13 to meet the assembly requirements of the filter assembly.

[0075] During later use, the filter assembly is disassembled from the connection body 1 without causing damage to the structure of the connection body 1, thereby improving the reliability of use.

[0076] Among them, in order to facilitate disassembly, the first connecting port 13 is a threaded port, and an external thread is arranged on the outer circumference of the port of the filter bottle 3, and the filter bottle 3 is threadedly connected in the first connecting port 13; a structural reinforcement part is also arranged on the outer wall of the filter bottle 3, and the structural reinforcement part is adjacent to the external thread.

[0077] Specifically, during the maintenance of the filter 500 , the filter bottle 3 can be removed from the connecting body 1 as needed, and the filter bottle 3 is installed in the first connecting port 13 by means of a threaded connection.

[0078] 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.

[0079] 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.

[0080] Alternatively, 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 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.

[0081] 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.

[0082] 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.

[0083] In order to facilitate the processing of the internal water flow path in the connecting body 1, the connecting body 1 adopts a split structure, that is, the connecting body 1 includes a first connecting member 15 and a second connecting member 16, the first connecting member 15 is provided with the water inlet connecting pipe 11 and the water outlet connecting pipe 12, an installation cavity is formed in the second connecting member 16, and the second connecting member 16 is provided with a first connecting port 13 connected to the installation cavity; the first connecting member 15 and the second connecting member 16 are fixedly connected together, the water inlet connecting pipe 11 and the water outlet connecting pipe 12 are respectively connected to the installation cavity, the inlet 201 of the filter element 2 is located in the filter bottle 3, and the outlet 202 of the filter element 2 is located in the installation cavity.

[0084] Specifically, for the connection body 1 , since the interior thereof needs to meet two independent water flow requirements of water inlet and water outlet, in order to simplify the processing difficulty, a water inlet connecting pipe 11 and a water outlet connecting pipe 12 are provided on the first connecting member 15 .

[0085] Embodiment 4, as Figure 14-18As shown, in order to meet the requirements of water inlet and outlet inside the connection body 1 and meet the installation design requirements of compact structure and miniaturization, the following structural improvements are made to the connection body 1.

[0086] The first connecting member 15 is a tee pipe, the three ends of which respectively form the water inlet connecting pipe 11, the water outlet connecting pipe 12 and the auxiliary connecting pipe 153, and the water inlet connecting pipe 11 and the auxiliary connecting pipe 153 are arranged in back-to-back relationship; The second connecting member 16 is provided with a communication port 163, and the communication port 163 is connected to the installation cavity; The filter 500 further includes an intermediate tube 4 and a water separator 5. The water separator 5 is annular in structure. An annular spacer 51 is provided on the outer circumference of the water separator 5. The annular spacer 51 divides the outer circumference of the water separator 5 into a first water flow area 52 and a second water flow area 53. The water divider 5 is arranged in the installation cavity, 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, 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 intermediate tube 4 is arranged in the water inlet connecting tube 11, and 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 passes through the connecting port 163 and 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, and the water outlet connecting tube 12 is connected to the water outlet cavity through the auxiliary flow channel 111 and the connecting port 163, and the inner tube port of the intermediate tube 4 is connected to the water inlet cavity.

[0087] Specifically, for the first connecting member 15, it is a three-way pipe structure as a whole, thereby correspondingly forming an inlet connecting pipe 11 and an outlet connecting pipe 12, and the other pipe opening of the three-way pipe will form an auxiliary connecting pipe 153, which can be connected to the connecting port 163 of the second connecting member 16 through the auxiliary connecting pipe 153.

[0088] The water inlet connecting pipe 11 and the water outlet connecting pipe 12 on the first connecting member 15 must meet the requirements of water inlet and outlet, and by setting 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 connecting member 15 is a three-way pipe structure, so that the auxiliary flow channel 111 and the water outlet connecting pipe 12 are connected to each other. After the first connecting member 15 is connected to the second connecting member 16, the auxiliary connecting pipe 153 is connected to the connecting port 163, so that the auxiliary flow channel 111 is connected to the water outlet cavity through the connecting port 163. At the same time, the pipe opening at the inner end of the intermediate pipe 4 extends into the installation cavity of the second connecting member 16 through the auxiliary connecting pipe 153 and the connecting port 163 to achieve communication with the water inlet cavity.

[0089] 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 first connecting member 15 is more compact and small, thereby meeting the miniaturized design requirement.

[0090] The water divider 5 arranged in the installation cavity of the second connecting member 16 is used to separate the water outlet cavity and the water inlet cavity in the installation cavity of the second connecting member 16. To this end, after the water divider 5 is installed in the installation cavity of the second connecting member 16, the annular spacer 51 is located on one side of the connecting port 163, thereby separating the water inlet cavity and the water outlet cavity in the installation cavity of the second connecting member 16.

[0091] 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.

[0092] The water flowing from the water inlet connecting pipe 11 through the intermediate pipe 4 into the installation cavity of the second connecting member 16 flows through the first water flow area 52 and then enters the filter bottle 3 and the filter element 2 for filtering.

[0093] The water filtered by the filter element 2 flows from the second flow area to the communication port 163 , and flows from the outer wall of the intermediate pipe 4 into the water outlet connecting pipe 12 through the auxiliary flow channel 111 .

[0094] In some embodiments, 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 arranged opposite to the communication port 163, and the side of the plug-in port 55 is provided with a through port 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 water inlet cavity through the through opening 56 .

[0095] Specifically, since both the inlet and outlet water need to enter and exit through the connecting port 163 on the second connecting member 16, 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.

[0096] 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.

[0097] 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 filter 500, while 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 filter 500.

[0098] 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.

[0099] 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 by the second water flow area 53 and flows into the auxiliary flow channel 111 through the connecting port 163.

[0100] 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.

[0101] 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 .

[0102] Specifically, since the annular spacer 51 is used to separate the water inlet cavity and the water outlet cavity in the installation cavity of the second connecting member 16, 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.

[0103] 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.

[0104] 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.

[0105] At the same time, in order to more effectively seal and separate the water inlet cavity and the water outlet cavity, the second water flow area 53 is provided with first sealing rings on both sides. The first sealing rings on both sides are squeezed and deformed to form two sealing areas to ensure that the second water flow area 53 is connected with the connecting port 163.

[0106] Embodiment 5, as Figure 14-Figure 21 As shown, in order to meet the requirement of convenient disassembly of the filter element 2 and realize the separate disassembly of the filter element 2 for maintenance without disassembly of the filter bottle 3, the installation structure of the filter element 2 is improved and designed as follows.

[0107] For the connecting body 1, the installation cavity formed by it is a structure with two ends open, so that one port of the installation cavity forms a first connection port 13 to meet the installation requirements of the filter bottle 3, and the filter element 2 will form a disassembly port 164 through another port formed on the connecting body 1 by the installation cavity, and the disassembly port 164 is used to meet the requirements of disassembly and assembly of the filter element 2.

[0108] Specifically, the two ends of the second connecting member 16 are open structures, one end of the second connecting member 16 forms the first connecting port 13, and the other end of the second connecting member 16 forms a disassembly port 164; the filter element 2 is inserted into the installation cavity through the disassembly port 164 and extends into the filter bottle 3.

[0109] In order to achieve a sealed assembly connection after the filter element 2 is inserted into the second connector 16, the inlet 201 is provided at one end of the filter element 2, the outlet 202 is provided at the other end of the filter element 2, two second sealing rings are provided on the filter element 2, the outlet 202 is located between the two second sealing rings, the filter element 2 is inserted into the water separator 5, the second sealing ring is squeezed between the filter element 2 and the water separator 5, and the through hole 57 is located between the two second sealing rings.

[0110] Specifically, the two sealing rings configured on the filter element 2 are distributed on both sides of the outlet 202. After the filter element 2 is inserted into the second connecting member 16, the end of the filter element 2 with the outlet 202 is located in the water separator 5, and the second sealing ring is squeezed on the inner surface of the water separator 5 to meet the sealing requirements of the filter element 2 assembly through the second sealing ring.

[0111] When the filter element 2 needs to be removed for maintenance or replacement during use, the filter element 2 can be removed from the second connecting member 16 through the disassembly port 164 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.

[0112] In one embodiment of the present application, for the filter element 2, its performance entity can adopt the following method to meet the requirements of disassembly and assembly.

[0113] The filter element 2 includes a shell 21, a core 22 and a filter mesh sleeve 24. The inlet 201 is provided at one end of the shell 21, and the outlet 202 is provided at the other end of the shell 21. The core 22 is located in the shell 21, and the filter mesh sleeve 24 is sleeved on the outside of the shell 21 and covers the inlet 201.

[0114] The shell 21 is inserted into the water separator 5 and the filter bottle 3 via the disassembly port 164 .

[0115] In some embodiments, the shell 21 includes a cylinder 211 and a knob 210, the cylinder 211 is formed with the inlet 201 and the outlet 202, the end of the cylinder 211 provided with the outlet 202 is arranged on the knob 210, the cylinder 211 is provided with the second sealing ring, the knob 210 is also provided with the second sealing ring, the outlet 202 is formed on the side wall of the cylinder 211 and is located between two second sealing rings; the knob 210 is detachably arranged on the water separator 5, the cylinder 211 is inserted into the water separator 5 and the filter bottle 3, one of the second sealing rings is clamped between the cylinder 211 and the inner wall of the water separator 5, and the other second sealing ring is clamped between the cylinder 211 and the inner wall of the water separator 5.

[0116] Specifically, in order to facilitate the user to disassemble and assemble the filter element 2, the filter element 2 is detachably connected to the water separator 5 through a knob 210. For the filter element 2, it uses a cylinder 211 to hold filter materials, mineralized materials and other conventional water quality optimization materials. The end of the cylinder 211 with an outlet 202 is connected to the knob 210, and then connected to the water separator 5 through the knob 210 to realize the assembly of the filter element 2 to the water separator 5.

[0117] At the same time, the second sealing ring on the cylinder 211 can cooperate with the water divider 5 to isolate the outlet 202 from the water inlet cavity formed in the cylinder 211. The second sealing ring provided on the knob 210 can achieve the sealing of the outlet 202 in the water divider 5 to ensure that the water output from the outlet 202 flows into the second water flow area 53 through the through-hole 57.

[0118] In some embodiments, there may be various structural forms for the detachable connection between the knob 210 and the water divider 5 , for example, the knob 210 is threadedly connected to the water divider 5 .

[0119] Alternatively, a latch tongue is provided on the periphery of the knob 210 , and a latch groove 59 is formed on the inner wall of the water divider 5 . The latch groove 59 extends transversely on the inner wall of the water divider 5 around the axial direction of the water divider 5 , and the latch tongue is latched in the latch groove 59 .

[0120] Specifically, in order to facilitate the user or operator to disassemble and assemble, the knob 210 is installed on the water divider 5 by rotating and clamping. That is, after the cylinder 211 passes through the water divider 5 and extends into the filter bottle 3, the corresponding part of the knob 210 will extend into the water divider 5, and after the knob 210 is rotated, the clamping tongue slides and clamps into the clamping groove 59, so that the knob 210 is assembled on the water divider 5.

[0121] When the knob 210 is in use, the angle that the user needs to rotate the knob 210 during disassembly and assembly is small, thereby facilitating the disassembly and assembly operation.

[0122] In order to facilitate the user to drive the knob 210 to rotate, a paddle 2104 may be provided on the end surface of the knob 210, and the user pinches the paddle 2104 to rotate the knob 210 to drive the knob 210 to rotate. In addition, in order to optimize the appearance effect, a decorative cap 2105 may be provided on the outside of the knob 210, and the decorative cap 2105 may be clamped on the paddle 2104 and arranged on the outside of the knob 210 to make the overall appearance more beautiful. The outer circumference of the decorative cap 2105 may be provided with a plurality of ribs or grooves to increase friction and facilitate the user to rotate the decorative cap 2105 by hand.

[0123] Furthermore, since the water divider 5 is generally made of plastic material, the slot 59 formed by the water divider 5 needs to meet the requirements of the filter element 2 for disassembly and assembly. During the disassembly and assembly process, the part where the slot 59 is formed will be frequently stressed, especially the part where the slot 59 is close to the edge of the water divider 5 is prone to damage. In order to improve the reliability of use, the second connecting member 16 made of metal material can be used to further strengthen the protection of the part where the slot 59 is formed on the water divider 5, and the specific structural design is as follows.

[0124] like Figure 14-15 As shown, the edge of the disassembly and assembly opening 164 of the second connecting member 16 is provided with an inner flange 165 , and the inner flange 165 covers the outer side of the portion of the water divider 5 having the clamping groove 59 .

[0125] Specifically, during the processing of the second connecting member 16, the edge of the disassembly opening 164 forms an inner flange 165. After the water diverter 5 is installed in the second connecting member 16, the first connecting member 15, the second connecting member 16 and the water diverter 5 will jointly form a diverter valve body for diverting the flow of water. As for the water diverter 5 assembled in the second connecting member 16, the clamping groove 59 formed thereon is used for later assembly of the filter element 2. The clamping groove 59 portion of the water diverter 5 will receive the external force generated by the clamping during the disassembly process. At this time, the portion of the water diverter 5 on the outer side of the clamping groove 59 is prone to damage. By providing the inner flange 165 on the disassembly opening 164 of the second connecting member 16, the inner flange 165 will be close to the portion of the water diverter 5 with the clamping groove 59.

[0126] During use, when the latch tongue on the knob 210 slides into the slot 59 and is stuck in the slot 59, the inner flange 165 on the outside of the slot 59 can support the slot 59, thereby strengthening the structure of the slot 59 and improving the reliability of use.

[0127] In order to improve the connection reliability between the knob 210 and the water divider 5, the knob 210 may be provided with a plurality of latching tongues, and correspondingly, the water divider 5 is provided with a plurality of latching grooves 59, and the latching tongues will slide into the corresponding latching grooves 59. Similarly, the outer side of each latching groove 59 is provided with a corresponding inner flange 165.

[0128] In addition, in order to guide the knob 210 to slide into the slot 59 , a first guiding slope 591 is formed at the end of the slot 59 away from its notch, and the first guiding slope 591 extends obliquely toward the notch of another adjacent slot 59 .

[0129] Specifically, during the process of rotating the knob 210 , the latch tongue on the knob 210 can be guided by the first guide slope 591 to slide toward the notch direction of the corresponding latch groove 59 and be latched into the latch groove 59 .

[0130] Meanwhile, for the inner flange 165, a second guide slope 166 is formed at one end of the inner flange 165, and the second guide slope 166 overlaps the first guide slope 591 and has the same inclination direction as the first guide slope 591. During the assembly of the knob 210, the user does not need to accurately adjust the position of the latch tongue, but only needs to dock the knob 210 in the disassembly opening 164 of the second connector 16 and then rotate it in the locking direction, and the latch tongue will slide into the slot 59 via the first guide slope 591 or sequentially via the second guide slope 166 and the first guide slope 591, so as to facilitate the user's use.

[0131] In another embodiment, after long-term use, the filter material in the cylinder 211 is easily clogged by scale and becomes ineffective. In order to reduce maintenance costs, the cylinder 211 and the knob 210 are connected by a structure that is easy to disassemble and assemble.

[0132] Specifically, a first connection portion 2111 is provided on the end of the cylinder 211 provided with the outlet 202, and a second connection portion 2101 is provided on the knob 210, and the first connection portion 2111 and the second connection portion 2101 are detachably connected together.

[0133] When the filter element 2 needs to be assembled, the first connection part 2111 and the second connection part 2101 cooperate with each other to assemble the cylinder 211 and the knob 210. After the filter element 2 is removed from the second connecting member 16, the cylinder 211 can be separated from the knob 210, so that the cylinder 211 with new filter material can be assembled with the knob 210 and then reinstalled into the second connecting member 16 for use. The knob 210 can be reused, reducing the number of parts to be replaced, thereby reducing maintenance costs and usage costs.

[0134] There are many ways to connect the first connection part 2111 and the second connection part 2101. For example, the first connection part 2111 and the second connection part 2101 are threadedly connected together.

[0135] Alternatively, an installation slot 2102 is provided at the end where the knob 210 is connected to the cylinder 211, the first connecting portion 2111 is an elastic claw provided on the outer wall of the cylinder 211, and the second connecting portion 2101 is a clamping protrusion provided on the inner wall of the installation slot 2102, and the elastic claw is clamped on the clamping protrusion.

[0136] Specifically, two elastic claws are symmetrically arranged on both sides of the outer wall of the cylinder 211 to serve as the first connection part 2111, and correspondingly, a corresponding clamping protrusion is arranged in the installation slot 2102 formed by the knob 210 to serve as the second connection part 2101. When the cylinder 211 and the knob 210 are assembled, the end of the cylinder 211 with the outlet 202 is inserted into the installation slot 2102, and the elastic claw is squeezed by the inner wall of the installation slot 2102 to deform and pass over the clamping protrusion, and finally, the elastic claw is clamped on the clamping protrusion provided in the installation slot 2102.

[0137] When the barrel 211 needs to be disassembled, the user only needs to press the elastic claws on both sides to disengage the clamping protrusions, and then the barrel 211 can be pulled out of the installation slot 2102. The first connecting portion 2111 and the second connecting portion 2101 are clamped, making the disassembly and assembly process faster and more convenient, thereby improving the convenience of use.

[0138] In one embodiment, in order to improve the assembly accuracy between the cylinder 211 and the knob 210, the cylinder 211 has an end portion of the outlet 202 to form a back-to-back positioning surface 2112, the elastic claw is arranged on the positioning surface 2112, and a positioning rib 2103 is provided in the mounting slot 2102, and the positioning rib 2103 is abutted against the positioning surface 2112.

[0139] Specifically, during the assembly process, the end of the cylinder 211 having the outlet 202 is inserted into the installation slot 2102, and the positioning rib 2103 and the positioning surface 2112 cooperate and guide each other, so that the first connection part 2111 and the second connection part 2101 can be more accurately matched and connected.

[0140] In another embodiment, in order to further reduce the maintenance cost and reuse the cylinder 211, during maintenance, only the filter material in the cylinder 211 needs to be replaced, and the cylinder 211 is improved in structure as follows.

[0141] The end of the cylinder 211 provided with the inlet 201 forms a mounting opening, and a disassembled plug 2113 is provided in the mounting opening.

[0142] Specifically, after the filter element 2 is removed from the second connecting member 16, the plug 2113 can be pulled out from the installation port of the cylinder 211, so that the filter material in the cylinder 211 can be taken out, and after the filter mesh sleeve 24 inside and outside the cylinder 211 is cleaned with clean water, new filter material can be loaded into the cylinder 211, and then, after the plug 2113 is assembled, the filter element 2 can be reinstalled and used.

[0143] The plug 2113 is provided with a mounting groove 219 , and a permanent magnet 23 is disposed in the mounting groove 219 .

[0144] Specifically, by arranging the permanent magnet 23 in the installation groove 219, 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.

[0145] 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. For this purpose, the following structural improvements are made to the intermediate pipe 4.

[0146] The intermediate tube 4 is an eccentric tube, the outer end of which is sealed and connected to the inner tube wall of the water inlet connecting tube 11 , and the inner end of which is inserted into the plug port 55 . The plug port 55 and the connecting port 163 are arranged eccentrically with each other.

[0147] 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 163, 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 163, 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.

[0148] 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 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, thereby ensuring smooth flow of the outlet water flow.
