Description

Technical Field

[0001] This utility model relates to the field of shower heads, specifically to a shower head water channel shell structure. Background Technology

[0002] Existing shower heads mainly have multiple sets of water outlets on their front for dispersed rinsing. Different water outlets (such as number, diameter, and arrangement) are used to achieve different water effects (such as water rinsing density, intensity of a single water jet, etc.), thereby meeting the user's needs for different water effects from the shower head.

[0003] While the dispersed rinsing of a showerhead can rinse a large area of ​​the body, the water flow is distributed to multiple outlets, and the water output per unit time in the rinsing area of ​​a single outlet is limited. This cannot meet the needs of using a concentrated large volume of water to directly rinse specific areas (such as private parts). Rinsing with dispersed water flow requires repeatedly moving the showerhead or extending the rinsing time to achieve the desired effect, which not only reduces rinsing efficiency but may also increase water consumption. Utility Model Content

[0004] The purpose of this utility model is to provide a shower head water circuit housing structure that enables the shower head to meet the needs of normal decentralized water rinsing while also achieving the effect of concentrated large water volume rinsing, thereby improving the flexibility of shower head use, ensuring rinsing efficiency, and reducing the risk of water waste.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A shower head water channel housing structure, comprising:

[0007] The main body is a hollow structure. A water inlet channel is provided on the bottom end face of the main body, and a first water outlet channel is provided on the top end face of the main body. The first water outlet channel and the water inlet channel are connected by at least one liquid flow channel.

[0008] The water outlet has a second water outlet channel and a third water outlet channel. Several water outlets of the second water outlet channel and the third water outlet channel are located on the same side of the water outlet and the water outlet direction of the two channels is the same.

[0009] The main body is provided with a first diversion channel, a second diversion channel, and a switching cavity for installing the water distribution valve core. The second water outlet channel is connected to the switching cavity through the first diversion channel, and the third water outlet channel is connected to the switching cavity through the second diversion channel. The switching cavity and the water inlet channel are connected. The liquid flow channel is connected to the water inlet channel through the switching cavity. The water outlet direction of the first water outlet channel is set at an angle to the water outlet direction of the second water outlet channel.

[0010] As a further improvement to the above technical solution, the main body includes a water receiving component for connecting to an external water supply pipeline and a flow guide component for guiding the water flow in the water receiving component into different water outlet channels. The water inlet channel is located on the water receiving component, and the first water outlet channel, the first diversion channel, and the second diversion channel are all located on the flow guide component. When the water receiving component is inserted into and fixed on the flow guide component, the water receiving component and the flow guide component enclose a switching cavity and a liquid flow channel. The flow guide component is provided with several first through holes and second through holes. The first diversion channel communicates with the switching cavity through the first through hole, and the second diversion channel communicates with the switching cavity through the second through hole.

[0011] As a further improvement to the above technical solution, the water outlet component includes a first diverter and a second diverter. When the first diverter is inserted into and fixed to the main body, the two enclose each other to form a first receiving cavity and a second receiving cavity. The first receiving cavity is connected to the first diverting channel, and the second receiving cavity is connected to the second diverting channel. The second diverter is provided with several protrusions, and a first water outlet hole is opened through the protrusions along its central axis. When the second diverter is inserted into and fixed to the first diverter, the two enclose each other to form a third receiving cavity, and the protrusions pass through the second diverter. The first water outlet hole and the first receiving cavity are connected to form a second water outlet channel. The second diverter is provided with several second water outlet holes, and the first diverter is provided with several third through holes. The second receiving cavity is connected to the third receiving cavity through the third through holes. The second water outlet hole, the third receiving cavity, and the second receiving cavity are connected in sequence to form the third water outlet channel.

[0012] As a further improvement to the above technical solution, a mixing seat is provided inside the water inlet channel. The mixing seat is fixed to the main body, and several mixing channels are formed through the mixing seat along its axial direction. The mixing channels include a first channel, a second channel, and a third channel that are sequentially connected along the water flow output direction. The first channel is frustum-shaped, the second channel is cylindrical, and the third channel is an inverted frustum-shaped. The length of the first channel is greater than the length of the second channel and less than the length of the third channel.

[0013] As a further improvement to the above technical solution, it also includes a decorative shell for wrapping the main body. The decorative shell is a hollow structure with openings at both ends and includes a front shell and a rear shell. Both the front shell and the rear shell are inserted into the main body. The front shell and the rear shell are fixedly connected by a snap-fit ​​structure. The front shell has an embedded hole for exposing the outlets of the second and third water outlet channels on the water outlet component.

[0014] As a further improvement to the above technical solution, a guide head is snapped onto the decorative shell, and a flushing hole is opened on the guide head. The flushing hole is connected to the first water outlet channel, and the flushing hole is inclined towards the rear shell relative to the central axis of the first water outlet channel.

[0015] As a further improvement to the above technical solution, the number of the first water outlet holes is less than the number of the second water outlet holes, the diameter of the first water outlet hole is greater than the diameter of the second water outlet hole, the first water outlet hole and the second water outlet hole are arranged in a dot matrix on the water outlet component, and the diameter of both gradually decreases along the water flow output direction.

[0016] As a further improvement to the above technical solution, there are two liquid flow channels, which are arranged symmetrically on the left and right sides relative to the switching chamber.

[0017] Compared with the prior art, this utility model has the following advantages and effects:

[0018] (1) By combining the structure of the main body and the water outlet, the water flow can achieve centralized rinsing through the first water outlet channel and decentralized rinsing through the second and third water outlet channels when the shower head is in use. This not only meets the user's normal shower needs (i.e. decentralized water rinsing) but also achieves the effect of centralized large-volume rinsing, improving the flexibility of shower head use, ensuring rinsing efficiency and reducing the risk of water waste.

[0019] (2) The present invention can be manufactured and processed separately by setting up an assembly structure between the main body and the water outlet, which reduces the manufacturing difficulty and ensures the integrity of the internal structure after the two are combined, and reduces manufacturing losses.

Detailed Implementation

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0035] See Figures 1-11This embodiment discloses a shower head water circuit housing structure, including a main body 1, a water outlet 2, and a decorative housing 3 for wrapping around the main body 1. The main body 1 is a hollow structure, with a water inlet channel 4 on the bottom end face and a first water outlet channel 51 on the top end face. The first water outlet channel 51 and the water inlet channel 4 are connected by at least one liquid flow channel 52. The water outlet 2 has a second water outlet channel 61 and a third water outlet channel 62, and several water outlets of the second water outlet channel 61 and the third water outlet channel 62 are located on the same side of the water outlet 2. On one side, and with the same water outlet direction for both, the main body 1 is provided with a first diversion channel 53, a second diversion channel 54, and a switching chamber 55 for installing the water distribution valve core. The second water outlet channel 61 is connected to the switching chamber 55 through the first diversion channel 53, and the third water outlet channel 62 is connected to the switching chamber 55 through the second diversion channel 54. The switching chamber 55 is connected to the water inlet channel 4, and the liquid flow channel 52 is connected to the water inlet channel 4 through the switching chamber 55. The water outlet direction of the first water outlet channel 51 is set at an angle to the water outlet direction of the second water outlet channel 61.

[0036] Under normal use, the water flow in the inlet channel 4 can enter the first diversion channel 53 through the switching chamber 55 and be output separately along the second outlet channel 61, or enter the second diversion channel 54 and be output separately along the third outlet channel 62, or simultaneously enter the first diversion channel 53 and the second diversion channel 54 and be output along the second outlet channel 61 and the third outlet channel 62, thus achieving decentralized flushing by outputting multiple water jets through multiple outlets. When centralized flushing is required, the water flow in the inlet channel 4 enters the liquid flow channel 52 through the switching chamber 55 and is output as a single water jet along the first outlet channel 51, ensuring the flushing volume and flushing effect of a specific area.

[0037] See Figures 2-8 The main body 1 includes a water receiving component 11 for connecting to an external water supply pipeline and a guide component 12 for guiding water flow from the water receiving component 11 into different water outlet channels. An inlet channel 4 is located on the water receiving component 11, and a first outlet channel 51, a first diversion channel 53, and a second diversion channel 54 are all located on the guide component 12. When the water receiving component 11 is inserted into and fixed to the guide component 12, a switching cavity 55 and a liquid flow channel 52 are formed between the water receiving component 11 and the guide component 12. The guide component 12 has several first through holes 13 and second through holes 14. The first diversion channel 53 communicates with the switching cavity 55 through the first through holes 13, and the second diversion channel 54 communicates with the switching cavity 55 through the second through holes 14. The modular structure of the main body 1 allows its components to be manufactured separately, ensuring the structural accuracy of the manufactured components and thus improving the structural integrity of the main body 1 while reducing manufacturing losses.

[0038] In this embodiment, there are two liquid flow channels 52, and the two liquid flow channels 52 are arranged symmetrically to the left and right of the switching chamber 55.

[0039] See Figures 7-9 The water outlet component 2 includes a first diverter 7 and a second diverter 8. When the first diverter 7 is inserted into and fixed to the main body 1, the two components together form a first receiving cavity 72 and a second receiving cavity 73. The first receiving cavity 72 is connected to the first diverting channel 53, and the second receiving cavity 73 is connected to the second diverting channel 54. The second diverter 8 is provided with a plurality of protrusions 81, and a first water outlet hole 71 is provided through the protrusions 81 along its central axis. When the second diverter 8 is inserted into and fixed to the first diverter 7, the two components together form a first receiving cavity 72 and a second receiving cavity 73. The first water outlet 72 and the first receiving cavity 72 are connected to form a third receiving cavity 83, and the protrusion 81 passes through the second diverter 8. The first water outlet 71 and the first receiving cavity 72 are connected to form a second water outlet channel 61. The second diverter 8 has several second water outlets 82, and the first diverter 7 has several third through holes 74. The second receiving cavity 73 is connected to the third receiving cavity 83 through the third through holes 74. The second water outlets 82, the third receiving cavity 83, and the second receiving cavity 73 are connected in sequence to form the third water outlet channel 62. Through the assembled structure of the water outlet component 2, the components of the water outlet component 2 can be manufactured individually, reducing the manufacturing difficulty of the water outlet component 2, ensuring the integrity and accuracy of the structure of the water outlet component 2, and thus ensuring the diversion and water outlet effect of the water outlet component 2.

[0040] In this embodiment, the number of first water outlet holes 71 is less than the number of second water outlet holes 82, the diameter of the first water outlet hole 71 is greater than the diameter of the second water outlet hole 82, the first water outlet hole 71 and the second water outlet hole 82 are arranged in a dot matrix on the water outlet component 2, and the diameter of both gradually decreases along the water flow output direction.

[0041] See Figure 10 , Figure 11 The water inlet channel 4 is provided with a mixing seat 41, which is fixed to the main body 1. Several mixing channels 42 are provided through the mixing seat 41 along its axial direction. The mixing channels 42 include a first channel 43, a second channel 44 and a third channel 45 connected in sequence along the water flow output direction. The first channel 43 is frustum-shaped, the second channel 44 is cylindrical, and the third channel 45 is inverted frustum-shaped. The length of the first channel 43 is greater than the length of the second channel 44 and less than the length of the third channel 45.

[0042] During use, the water flow mixed with air in the inlet channel 4 flows through the mixing channel 42. The mixing channel 42 guides and converges the water flow, which increases its flow rate and gathers the air contained within it. Then, the converged water flow is diffused out, allowing the water and air to mix again to form microbubble water. This ensures the uniformity of air mixing in the water flow and achieves the aeration effect of water flowing out of each outlet channel of the shower head.

[0043] In this embodiment, the hybrid seat 41 can be connected to the main body 1 by an interference fit.

[0044] See Figure 12 , Figure 13 The decorative housing 3 is a hollow structure with openings at both ends and includes a front housing 31 and a rear housing 32. Both the front housing 31 and the rear housing 32 are inserted into the main body 1. The front housing 31 and the rear housing 32 are fixedly connected by a snap-fit ​​structure, which improves the convenience of installing the decorative housing 3 on the main body 1. The front housing 31 has an embedded hole 33 for exposing the outlets of the second water outlet channel 61 and the third water outlet channel 62 on the water outlet component 2, which improves the appearance of the decorative housing 3 and the water outlet component 2 and enhances the visual harmony and aesthetics of the shower head.

[0045] See Figure 13 The decorative housing 3 is fitted with a guide head 9, which improves the stability of the connection between the front housing 31 and the rear housing 32. The guide head 9 is provided with a flushing hole 91, which is connected to the first water outlet channel 51. The flushing hole 91 is inclined toward the rear housing 32 relative to the central axis of the first water outlet channel 51, so that the water flow in the first water outlet channel 51 can be output at an angle relative to the shower head, reducing the risk that the water flow after rinsing will fall onto the flushing hole 91 and affect the normal output of water flow when rinsing from bottom to top with the shower head.

[0046] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
