Specifically, the connection channel 2104 is formed inside the integrated waterway component, the connection channel 2104 can convey externally input water to the water treatment filter element 240, and the water is conveyed to a user water terminal through the other connection channel 2104 after being treated by the water treatment filter element 240. And an external port 2103 for the integrated waterway assembly is formed to the rotatable connection hub 213 to enable the water treatment cartridge to be mounted to the connection hub 213.

The performance entity of the integrated waterway component is designed correspondingly according to the actual waterway design, and is exemplified as follows.

The integrated waterway part includes a housing 210, a temperature control valve cartridge 220 and a waterway control valve cartridge 230 provided on the housing 210, wherein a rotatable connection joint 213 is provided on the housing 210.

Specifically, the water treatment cartridge 240 is mounted on a rotatably coupled fitting 213 provided on the housing 210, and the housing 210 and its internally disposed coupling passage 2104 and cartridge together form an integrated waterway assembly. Because the connection joint 213 can rotate relative to the housing 210, when the water treatment filter element 240 needs to be disassembled, the connection joint 213 can be rotated, so that the water treatment filter element 240 is pulled out to the outside, and the user can conveniently disassemble the water treatment filter element; likewise, when assembling the water treatment cartridge 240, the connection joint 213 is rotated to an angular position suitable for installation to easily and quickly install the water treatment cartridge 240.

In some embodiments, since the water treatment cartridge 240 is configured, it is generally necessary to protect the water treatment cartridge 240, and for this reason, the housing 210, the temperature control cartridge 220, the waterway control cartridge 230, and the water treatment cartridge 240 form the water treatment apparatus 200, and the water treatment apparatus 200 is integrally installed in the housing 100, and the housing 100 and the water treatment apparatus 200 are assembled together to form the water treatment apparatus, and the water treatment apparatus generates corresponding functions when different usage scenarios are applied. For example: the water treatment equipment is arranged in a bath room and matched with a water heater for use, so that the water treatment equipment can be used as a bath machine; the water treatment equipment can also be arranged in a kitchen to be matched with a kitchen sink, and the specific use mode is not limited.

In some embodiments, there may be a variety of configurations for the installation of the water treatment cartridge 240. For example: the water treatment cartridge 240 is threadably coupled to the outer interface 2103.

In order to better meet the requirement of quick assembly and disassembly, the water treatment filter element 240 is inserted on the external interface 2103.

Specifically, the water treatment filter element 240 is mounted on the external interface 2103 by adopting a plug-in manner, so that a user can detach the water treatment filter element 240 only by plugging and unplugging the water treatment filter element 240.

In one embodiment, for the sake of connection reliability, the water treatment filter 240 is provided with a clamping member 241, the housing 100 is provided with a clamping seat 110, the clamping seat 110 is provided with a clamping groove 111, and the clamping member 241 is clamped in the clamping groove 111.

Specifically, when the water treatment cartridge 240 is installed, the connection joint 213 is rotated outwardly to facilitate the user's insertion of the water treatment cartridge 240 onto the external interface 2103. The water treatment cartridge 240 is rotated in communication with the connection fitting 213 to be installed into the housing 100, and the clip 241 is snapped into the clip groove 111 after the water treatment cartridge 240 is installed in place. The clamping piece 241 is matched with the clamping groove 111 so as to ensure that the water treatment filter element 240 can be firmly and reliably installed and fixed.

In another embodiment, to ensure that the water treatment cartridge 240 and the connection fitting 213 can be securely inserted together to avoid water leakage due to improper assembly, the edge of the outer port 2103 is further provided with a positioning opening 21031, and the clip 241 is further positioned in the positioning opening 21031.

Specifically, the connector 213 is provided with a positioning opening 21031 at the edge of the outer connector 2103, and a user needs to move the clamping member 241 into the positioning opening 21031 to achieve the installation in place when installing the water treatment cartridge 240. If the cartridge 240 is in place by being inserted into the connector 213, then the clip 241 is positioned out of the positioning opening 21031; in the process of rotating the connection joint 213 to clamp the clamping piece 241 into the clamping groove 111, the clamping piece 241 is not installed in place outside the positioning opening 21031, so that the clamping piece 241 and the clamping groove 111 are in a dislocation state, and the water treatment filter element 240 cannot be installed and fixed.

By means of the structural design, the water treatment filter element 240 and the connecting joint 213 can be guaranteed to be installed in place, and water leakage caused by the fact that the water treatment filter element is not installed in place is reduced, so that the use experience of a user is improved.

In another embodiment, in order to facilitate the installation of the connection joint 213, the housing 210 is provided with a connection seat 214, the end of the connection seat 214 is provided with an installation socket 215, the installation socket is connected with a corresponding connection channel, the side wall of the connection seat 214 is provided with an installation jack (not marked), and the installation jack is provided with a detachable limiting piece 216; the connection joint 213 is provided with a plug, and the outer circumference of the plug is provided with a limit groove 2131, and the limit piece 216 is clamped in the limit groove 2131.

Specifically, the connection joint 213 is also installed on the housing 210 in a plug-in manner, and the limit piece 216 and the limit groove 2131 cooperate with each other, so that, on one hand, the connection joint 213 is reliably connected to the housing 210 without being separated from the installation socket, and on the other hand, the requirement of rotation of the connection joint 213 relative to the housing 210 can be met.

The limiting piece 216 has a U-shaped structure, two mounting jacks are provided on the side wall of the connecting seat 214, two ends of the limiting piece 216 are respectively inserted into the corresponding mounting jacks, and the plug is located between two ends of the limiting piece 216. Specifically, the stop 216 straddles the two sides of the connection joint 213, providing a more reliable stop for the connection joint 213.

In addition, the limiting member 216 is further provided with a clamping portion (not labeled), and the connection base 214 is provided with a clamping mating portion, and the clamping portion is clamped on the clamping mating portion. Specifically, after the limiting member 216 is installed in place, the clamping portion and the clamping mating portion are clamped together, so as to ensure that the limiting member 216 is firmly and reliably installed on the connecting seat 214.

In another embodiment, in order to limit the rotation angle of the connection joint 213, a protruding rotation limiting block 217 is provided in the mounting socket, a limiting rib 2132 is provided on the outer circumference of the plug of the connection joint 213, and the rotation limiting block 217 is located between two ends of the limiting rib 2132.

Specifically, during the rotation process, the rotation limiting block 217 is located between two ends of the limiting rib 2132, and when the connection joint 213 rotates to the position of the maximum rotation angle towards the outside, the rotation limiting block 217 will abut against the corresponding end of the limiting rib 2132.

Based on the above technical solution, as shown in fig. 3-6, for the fixed installation mode of the water treatment filter element 240, in order to reliably support the water treatment filter element 240, and at the same time, meet the requirement of convenient disassembly and assembly, the supporting portion 120 may be configured in the casing 100; the water treatment cartridge 240 is inserted into the outer port 2103 through a water pipe inserted at an end portion thereof, and the other end portion of the water treatment cartridge 240 abuts against the support portion 120.

Specifically, in the process of installing the water treatment filter element 240, after the water treatment filter element 240 is installed on the external connector 2103 through the plug-in water pipe, the other end portion of the water treatment filter element 240 abuts against the supporting portion 120 configured by the casing 100, so that the other end portion of the water treatment filter element 240 can be supported by the supporting portion 120.

The two ends of the water treatment filter element 240 are respectively supported and fixed, so that the occurrence of falling of the water treatment filter element 240 caused by shaking can be effectively reduced in the use process, and the use reliability is improved; in addition, in the process of installing or detaching the water treatment filter element 240, the water treatment filter element 240 can be conveniently separated from the supporting part 120 or abutted against the supporting part 120 by pushing and pulling the water treatment filter element 240, so that the requirement of convenient disassembly and assembly is met.

In one embodiment, the support 120 is an elastic plate disposed on the casing 100, and one end of the elastic plate is disposed on the casing 100.

Specifically, the supporting portion 120 adopts the manner of the elastic plate, so that the supporting portion 120 has a certain elasticity, and when the water treatment filter element 240 is installed, the end portion of the water treatment filter element 240 abuts against the elastic plate to enable the elastic plate to generate a certain deformation, and then the elastic plate is utilized to provide a reliable support for the water treatment filter element 240.

And when the water treatment filter element 240 is disassembled, the requirement of convenient disassembly of the water treatment filter element 240 can be met by overcoming the elasticity of the elastic plate.

In one embodiment, the surface of the elastic plate contacting the end of the water treatment cartridge 240 forms an inclined surface 121 and a supporting surface 122 connected in sequence.

Specifically, the inclined surface 121 can facilitate movement of the end of the water treatment cartridge 240 via the inclined surface 121 when the water treatment cartridge 240 is installed, and the end of the water treatment cartridge 240 abuts against the support surface 122 after the water treatment cartridge 240 is installed in place. In addition, the elastic plate and the casing 100 are integrally formed for easy processing and reduced manufacturing cost.

In other embodiments, to further limit the end of the water treatment cartridge 240 that contacts the support 120, two sides of the support 120 are further provided with limiting portions 123, and the cartridge is located between the two limiting portions 123.

Specifically, the limiting portions on both sides of the supporting portion 120 form a limiting space, so that the end portion of the water treatment filter element 240, which is in contact with the supporting portion 120, can be limited in the limiting space, and the installation reliability is improved.

In some embodiments, at least one second mounting seat 104 may be disposed on the housing 100 along the length of the filter element, and a recess may be formed in the second mounting seat 104, in which the water treatment filter element 240 is disposed.

Specifically, after the two ends of the water treatment filter element 240 are respectively and fixedly installed through the external interface 2103 and the supporting part 120, at least one second installation seat is configured on the water treatment filter element 240 in the length direction, and the concave part formed by the second installation seat can further position and support the middle area of the water treatment filter element 240, so that the installation reliability is further improved.

Based on the above technical solution, a water inlet pipe 101 and a water outlet pipe 102 are provided on a casing 100, and an installation space is formed inside the casing 100, and a first installation seat 103 and a second installation seat 104 are provided in the installation space; the shell 210 is provided with a water inlet port 2101, a water outlet port 2102 and an outer port 2103; the water treatment filter element 240, the water treatment filter element 240 is used for carrying out water quality treatment on the water flow flowing in from the water inlet pipe and outputting the water from the water outlet pipe;

Wherein, integrated water route part and water treatment filter core 240 all set up in casing 100, and integrated water route part passes through shell 210 and sets up on the first mount pad, water treatment filter core 240 sets up on the second mount pad, the inlet tube is connected with inlet interface 2101, the outlet pipe is connected with outlet interface 2102, and water treatment filter core 240 connects on external interface 2103, and casing 100 is used for hanging the inlet tube and/or on the outlet pipe.

Specifically, in order to meet the installation requirements of the bathroom, a wall-mounted cabinet 100 is used, the cabinet 100 is suspended from the wall of the bathroom through the water inlet pipe and/or the water outlet pipe, and the integrated waterway component and the water treatment cartridge 240 are integrally installed in the cabinet 100.

In the process of installation in the user's home, the water inlet pipe is communicated with a water pipe network in the user's home, a water supply pipe orifice is usually reserved on the wall of the user's home, the water inlet pipe is installed on the water supply pipe orifice, and likewise, the water outlet pipe is connected with a water pipe of a water terminal in the user's home.

The water inlet pipe carrying case 100 is described below as an example.

The water inlet pipe is connected to a water supply pipe orifice buried in a wall of a user's home, the cabinet 100 is hung on the wall through the water inlet pipe, and the integrated waterway component and the water treatment filter element 240 in the cabinet 100 are fixedly installed in the cabinet 100 through corresponding installation seats.

The casing 100 is hung on a wall through the water inlet pipe or the water outlet pipe for installation so as to meet the requirement of wall installation, and meanwhile, the integrated waterway component and the water treatment filter element 240 are intensively installed in the casing 100 so as to realize compact design and meet the requirement of unified and rapid installation on site.

In some embodiments, the housing 100 is generally flat in configuration. Thus, after the cabinet 100 is mounted on the wall, since the cabinet 100 has a flat structure, the integrated waterway component and the water treatment cartridge 240 can be mounted by making the cabinet 100 abut against the wall and using an area of the wall to form an internal mounting space. In addition, the flat structure of the housing 100 can reduce the occupation of the effective bathroom space of the housing 100 and reduce the collision of users with the housing 100 in the bathing process. In addition, the integrated waterway component is integrated in the casing 100, and the wall-mounted installation height of the casing 100 is suitable for a user to operate the integrated waterway component, so that the casing 100 can be installed by using the installation space of the original water mixing valve in the user's home.

In one embodiment of the present application, the water inlet pipe passes through the back plate of the housing 210 and protrudes to the outside of the housing 210.

In particular, the inlet pipe extends from the back plate of the housing 210 to the outside to connect to the water supply pipe orifice on the wall of the user's home. Typically, the inlet conduit is disposed laterally to further facilitate carrying the housing 100 and the integrated waterway components and water treatment cartridge 240 within the housing 100 through the inlet conduit. In addition, the water introduced into the integrated waterway part is generally divided into cold water and hot water, and the water inlet pipes may be respectively disposed at both sides of the cabinet 100, one of which is used for transporting cold water and the other of which is used for transporting hot water.

In one embodiment, as shown in fig. 7, for facilitating the installation of the operator on site, the water inlet pipe comprises a first pipe body 1011 and a second pipe body 1012, the first pipe body 1011 is provided with an external thread part 1013, the axis of the external thread part 1013 is deviated from the axis of the first pipe body 1011, the first pipe body 1011 is inserted in the second pipe body 1012 in a sealing manner, the external thread part 1013 is located outside the casing 100, and the second pipe body 1012 is connected with the water inlet port 2101.

Specifically, in the actual assembly process, due to the difference of decoration construction in the user's home, the distance between two pipe orifices of the external water pipe for conveying cold and hot water is different, and the external thread part 1013 of the first pipe 1011 is arranged in an off-axis arrangement mode, and after the external thread part 1013 is connected with the pipe orifice on the wall, the external thread part 1013 is rotated by a proper angle, so that the distance between the two first pipe orifices 1011 meets the installation distance between the two second pipe orifices fixedly installed on the casing 100, and the on-site quick installation can be facilitated, so as to improve the installation universality.

The first pipe 1011 and the second pipe 1012 are inserted, and after the installation position of the first pipe 1011 is adjusted, the first pipe 1011 is inserted into the corresponding second pipe 1012 to complete the assembly.

In another embodiment, in order to firmly and reliably connect the first pipe body 1011 and the second pipe body 1012, the outer diameter of the pipe section of the first pipe body 1011 inserted into the second pipe body 1012 gradually increases from outside to inside, and a screw hole is provided on the pipe wall of the second pipe body 1012, in which a locking screw 1014 is screwed, and the locking screw 1014 abuts against the outer pipe wall of the first pipe body 1011.

Specifically, when the user installs the two first pipes 1011 at home, the housing 100 is connected to the first pipe 1011 on the wall through the second pipe 1012 after the two first pipes 1011 are installed and adjusted. And, after the first pipe 1011 is inserted into the second pipe 1012 and the distance position between the cabinet 100 and the wall is adjusted, the first pipe 1011 is fastened in the second pipe 1012 by the locking screw 1014.

Since the outer wall of the first pipe body 1011 has a variable diameter structure, the larger the outer wall diameter of the first pipe body 1011 inserted into the second pipe body 1012, the end of the locking screw 1014 is abutted against the outer wall of the first pipe body 1011 by tightening the locking screw 1014, thereby preventing the first pipe body 1011 from being separated from the second pipe body 1012, and improving the connection reliability between the first pipe body 1011 and the second pipe body 1012.
