Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, specifically to a water-passing structure and a shower device. Background Technology

[0002] Existing shower systems typically have multiple water outlets to achieve various water flow modes. Some have different function outlets in the overhead shower head, while others have both an overhead shower head and side sprays. The piping connecting the multi-functional overhead shower head or the overhead and side sprays uses a pipe-in-pipe structure with an inner pipe inside the shower pipe to reduce the space occupied in the shower. Some systems have two inner pipes running side by side inside the shower pipe to form two water paths, resulting in a larger shower pipe size. Other systems have one inner pipe coaxially installed in the shower pipe, forming inner and outer water channels in the inner pipe and between the inner pipe and the shower pipe. The water inlet of the piping is connected to a water distribution valve or a connector. The water distribution valve or connector has a corresponding matching connection end for the pipe-in-pipe structure. For coaxial pipe-in-pipe structures with smaller shower pipe diameters, the connection end of the corresponding water distribution valve or connector is limited by the size of the shower pipe diameter, resulting in a smaller flow rate into the inner and / or outer water channels. This makes it difficult to simultaneously meet the national standard's minimum flow rate requirements and the user's needs, especially when the water pressure is low. Utility Model Content

[0003] The purpose of this utility model is to provide a water passage structure and a shower device including the water passage structure.

[0012] The sixth technical solution is based on the fifth technical solution and further includes a fastener, wherein the inner tube is limited relative to the outer tube in a first direction by the fastener passing through the outer tube.

[0013] The seventh technical solution is based on the sixth technical solution, wherein the mating part is provided with a blind hole, and the fastener mates with the blind hole; the mating part is provided with sealing parts on both sides of the blind hole along the first direction to seal against the inner wall of the outer tube.

[0014] The eighth technical solution is based on the first technical solution, wherein the end of the inner pipe away from the water-passing connector assembly along the first direction blocks the second water passage, and the side wall of the outer pipe is provided with a water outlet corresponding to the second water passage.

[0015] The ninth technical solution is based on the first technical solution and further includes a water distribution valve, which has at least two water distribution ports and a valve core for controlling the opening and closing of the water passages at the water distribution ports; the water distribution valve is fixedly connected to the water passage connector assembly so that two of the water distribution ports are correspondingly connected to the first water passage and the second water passage.

[0017] The eleventh technical solution is based on the tenth technical solution, wherein the first water outlet component includes a top-mounted shower and the second water outlet component includes a rear-mounted shower.

[0018] Compared with existing technologies, the above technical solution has the following beneficial effects:

[0019] In the first technical solution, the water-passing component includes an outer pipe and an inner pipe fixed in the outer pipe. The inner pipe has a first water passage, and the space between the inner pipe and the outer pipe forms a second water passage. The water-passing connector assembly has a first water passage and a second water passage. The outlet ends of the first water passage and the second water passage are respectively provided with a first connecting pipe and a second connecting pipe extending along a first direction. The axes of the first connecting pipe and the second connecting pipe are parallel. The first connecting pipe includes a first connecting section and a second connecting section. The second connecting section is sealed and inserted into the inner pipe to connect the first water passage and the first water passage. The second connecting pipe is directly or indirectly sealed to the outer pipe. The sealing connection connects the second water passage and the second water channel; a portion of the sidewall of the first connecting section and a portion of the sidewall of the second connecting pipe are shared; compared with the prior art, under the same shower pipe diameter, the sharing of a portion of the sidewall of the first connecting section of the first connecting pipe and a portion of the sidewall of the second connecting pipe reduces the total cross-sectional area of ​​the sidewalls of the first and second connecting pipes, thereby increasing the water flow area of ​​the first and / or second connecting pipes, and thus increasing the water flow of the first and / or second water channels, which better meets the minimum flow requirements of the national standard and user needs.

[0020] In the second technical solution, the second connecting pipe is screwed into the first connector, and then sealed and inserted into the outer pipe through the first connector. This is an indirect sealing and insertion method between the second connecting pipe and the outer pipe.

[0021] In the third technical solution, the water-passing connector assembly of this structure has a relatively compact spatial layout and is convenient for connecting pipes in different directions.

[0022] In the fourth technical solution, the inner tube is sealed and plugged into the second connecting section and the outer tube through the first plug end and the second plug end located at both ends of the inner tube, respectively. While facilitating assembly, the second plug end blocks the second water passage along the first direction, thus isolating the water passage formed by the second water passage and the second water passage from the water passage formed by the first water passage and the first water passage.

[0023] In the fifth technical solution, the inner tube is fitted with the inner wall of the outer tube by setting a mating part, which increases the connection point with the outer tube in the first direction, thereby enhancing the support between the inner and outer tubes and reducing the vibration and noise caused by water flow impact. The flow hole is used to keep the second water passage unobstructed.

[0024] In the sixth technical solution, the inner tube is limited relative to the outer tube in the first direction by fasteners passing through the outer tube, thereby preventing the inner tube from moving relative to the outer tube when the water pressure is too high.

[0025] In the seventh technical solution, the fastener and the blind hole are matched, and the mating part is sealed against the inner wall of the outer pipe by the sealing part set on both sides of the blind hole along the first direction, which can prevent the water in the second water passage from leaking out of the blind hole.

[0026] In the eighth technical solution, the end of the inner pipe away from the water connector assembly along the first direction blocks the second water passage, and the side wall of the outer pipe is provided with a water outlet corresponding to the second water passage, thereby forming a lateral water outlet and improving the shower experience.

[0027] In the ninth technical solution, each water outlet is equipped with a corresponding valve core to control the flow of water in that water circuit, making the operation relatively simple.

[0028] In the tenth technical solution, the shower device has two water outlet components and includes the water passage structure described in any one of the first to ninth technical solutions, thus achieving the corresponding technical effect.

[0029] In the eleventh technical solution, the first water outlet component includes a top-mounted shower, and the second water outlet component includes a rear-mounted shower, providing more shower modes and enhancing the shower experience. Attached Figure Description

[0059] Compared with the prior art, this embodiment has the following beneficial effects:

[0060] In this embodiment, the water-passing component 1 includes an outer pipe 12 and an inner pipe 11 fixed in the outer pipe 12. The inner pipe 11 is provided with a first water passage S1, and the space between the inner pipe 11 and the outer pipe 12 forms a second water passage S2. The water-passing connector assembly 2 includes an adapter 21 and a first connector 22. The adapter 21 includes a first connecting pipe 211, a second connecting pipe 212, a third connecting pipe 213, and a fourth connecting pipe 214.

The third connecting pipe 213 extends along a second direction and connects to the first connecting pipe 211. Their cavities are interconnected to form a first water passage W1. The fourth connecting pipe 214 extends along a third direction and connects to the second connecting pipe 212. Their cavities are interconnected to form a second water passage W2. The first connecting pipe 211 is divided into a first connecting segment 2111 and a second connecting segment 2111 by a first plane P1. 112, the second connecting section 2112 is sealed and inserted into the inner pipe 11 to connect the first water passage W1 and the first water passage S1. The second connecting pipe 212 is sealed and inserted into the outer pipe 12 through the first joint 22 to connect the second water passage W2 and the second water passage S2. Part of the side wall of the first connecting section 2111 and part of the side wall of the second connecting pipe 212 are shared. Compared with the prior art, when the shower pipe diameter is the same, since part of the side wall of the first connecting section 2111 of the first connecting pipe 211 and part of the side wall of the second connecting pipe 212 are shared, the total cross-sectional area of ​​the side walls of the first connecting pipe 211 and the second connecting pipe 212 is reduced. Correspondingly, the water passage area of ​​the first connecting pipe 211 and / or the second connecting pipe 212 can be increased, thereby increasing the water passage volume of the first water passage S1 and / or the second water passage S2, which better meets the minimum flow requirements of the national standard and user needs.

[0061] In this embodiment, the second connecting pipe 212 is indirectly and sealed to the outer pipe 12 through the first connector 22, which facilitates the assembly of the water connector assembly 2 with the outer pipe 12 and related components such as the water distribution valve 5.

[0062] In this embodiment, the first connecting pipe 211 and the second connecting pipe 212 extend along the first direction, the third connecting pipe 213 extends along the second direction and connects to the first connecting pipe 211, and their cavities are interconnected to form the first water passage W1.

While facilitating assembly, the second plug-in end 112 blocks the second water passage S2 along the first direction, so that the water passage formed by the second water passage W2 and the second water passage S2 is isolated from the water passage formed by the first water passage W1 and the first water passage S1. Several second water outlets 122 are provided on the side wall of the outer tube 12 between the first plug-in end 111 and the second plug-in end 112, thus forming lateral water outlet and improving the shower experience.

[0064] In this embodiment, the inner tube 11 is fitted with the inner wall of the outer tube 12 by setting a fitting part 113, which increases the connection point with the outer tube 12 in the first direction, thereby enhancing the support between the inner tube 11 and the outer tube 12 and reducing the vibration and noise caused by water flow impact.

[0065] In this embodiment, the inner tube 11 is provided with a blind hole 1132 in the mating part 113, and the fastener 3 passes through the first through hole 121 to be threadedly engaged with the blind hole 1132, thereby limiting the inner tube 11 relative to the outer tube 12 in the first direction, which can prevent the inner tube 11 from moving relative to the outer tube 12 when the water pressure is too high; and, the mating part 113 is provided with sealing parts 1133 on both sides of the blind hole 1132 in the first direction to seal against the inner wall of the outer tube 12, which can prevent the water in the second water passage S2 from leaking out through the blind hole 1132 and the first through hole 121.

[0066] In this embodiment, the water distribution valve 5 controls the flow of water by setting one valve core corresponding to one water distribution port, which is relatively simple to operate.
