Description

Technical Field

[0001] This invention relates to a water passage housing structure of a shower head used in a bathroom or the like.

Background Art

[0002] Conventional shower heads mainly have a structure in which a plurality of sets of water discharge holes are provided on their front surfaces for performing dispersed cleaning. By changing the form of the provided water discharge holes (for example, number, hole diameter, arrangement method, etc.), different water discharge effects (for example, water flow density during cleaning, cleaning strength of a single water column, etc.) can be realized to meet various water discharge needs of users.

[0003] However, while dispersed cleaning is suitable for cleaning a wide body area, since the water flow is dispersed and output from a plurality of water discharge holes, the water discharge volume per unit time by a single water discharge hole is limited, and it cannot meet the need for intensively directly cleaning a specific part (for example, a delicate zone) with a large flow rate. Therefore, in order to obtain a desired cleaning effect with a dispersed water flow, it is necessary to repeatedly move the shower head or extend the cleaning time, which not only causes a decrease in cleaning efficiency but may also lead to an increase in water resource consumption.

[0004] A shower nozzle that discharges a normal dispersed water flow and a shower head capable of discharging a water flow from a small-diameter nozzle have also been proposed (for example, see Patent Document 1).

MODE FOR CARRYING OUT THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 11. For each figure, the corresponding parts are given the same reference numerals, and redundant explanations may be omitted, or for parts not shown in the figure being described, reference numerals shown in other figures may be used for reference. The following examples are for illustrative purposes only and the utility model is not limited to them. [Examples]

[0018] Referring to Figures 1 to 11, the showerhead water channel housing structure according to this embodiment includes a main member 1, a water outlet member 2, and a decorative housing 3 that covers the main member 1 from the outside. The main member 1 has a hollow structure, and a water supply passage 4 is provided at its bottom end surface, and a first water outlet passage 51 is provided at its top end surface. The first water outlet passage 51 and the water supply passage 4 are in communication via at least one flow path 52. The water outlet member 2 is provided with a second water outlet passage 61 and a third water outlet passage 62, and these multiple discharge ports are all located on the same side surface of the water outlet member 2 and have the same water discharge direction. The main member 1 is provided with a first diversion passage 53, a second diversion passage 54, and a switching chamber 55 for installing a water diversion valve core. The second water outlet passage 61 is in communication with the switching chamber 55 via the first diversion passage 53, and the third water outlet passage 62 is in communication with the switching chamber 55 via the second diversion passage 54. The switching chamber 55 is in communication with the water supply passage 4, and the flow path 52 is in communication with the water supply passage 4 via the switching chamber 55. In addition, the discharge direction of the first water outlet passage 51 is positioned at a predetermined angle with respect to the discharge direction of the second water outlet passage 61.

[0019] Under normal use, the water flow in the water supply passage 4 flows into the first diversion passage 53 via the switching chamber 55 and is discharged alone from the second outlet passage 61, or flows into the second diversion passage 54 and is discharged alone from the third outlet passage 62, or flows into both simultaneously and is discharged from the second outlet passage 61 and the third outlet passage 62. This allows for dispersed cleaning as multiple water columns from multiple outlets. On the other hand, when concentrated cleaning is required, the water flow in the water supply passage 4 flows into the flow path 52 via the switching chamber 55 and is discharged as a single water column from the first outlet passage 51, ensuring sufficient water volume and cleaning effect for a specific area.

[0020] Referring to Figures 2 to 8, the main body member 1 includes a water-contacting member 11 for connecting to an external water supply pipe and a flow guide member 12 that guides the water flow within the water-contacting member 11 to different water outlet paths. The water supply passage 4 is provided in the water-contacting member 11, and the first water outlet passage 51, the first diversion passage 53, and the second diversion passage 54 are provided in the flow guide member 12. When the water-contacting member 11 is inserted into and fixed in the flow guide member 12, a switching chamber 55 and a flow path 52 are formed between them. The flow guide member 12 is provided with a plurality of first through holes 13 and second through holes 14, the first diversion passage 53 communicates with the switching chamber 55 via the first through hole 13, and the second diversion passage 54 communicates with the switching chamber 55 via the second through hole 14. With this assembly structure, it is possible to manufacture each component of the main body member 1 individually, ensuring the structural accuracy of the parts, improving the structural integrity of the main body member 1 as a whole, and contributing to the reduction of manufacturing losses.

[0021] In this embodiment, two flow paths 52 are provided, and they are arranged symmetrically with respect to the switching chamber 55.

[0022] Referring to Figures 7 to 9, the water outlet member 2 includes a first diversion member 7 and a second diversion member 8. When the first diversion member 7 is inserted into and fixed to the main member 1, a first containment chamber 72 and a second containment chamber 73 are formed between them. The first containment chamber 72 communicates with the first diversion passage 53, and the second containment chamber 73 communicates with the second diversion passage 54. The second diversion member 8 is provided with a plurality of protrusions 81, and each protrusion 81 has a first water outlet hole 71 that penetrates in the axial direction. When the second diversion member 8 is inserted into and fixed to the first diversion member 7, a third containment chamber 83 is formed between them, and the protrusions 81 are positioned to penetrate the second diversion member 8. The first water outlet hole 71 communicates with the first containment chamber 72 to form a second water outlet passage 61. In addition, the second diversion member 8 is provided with a plurality of second water outlet holes 82, and the first diversion member 7 is provided with a plurality of third through holes 74. The second containment chamber 73 communicates with the third containment chamber 83 via the third through-hole 74, and the second water outlet 82, the third containment chamber 83, and the second containment chamber 73 are sequentially connected to form the third water outlet passage 62. With this assembly structure, each component of the water outlet member 2 can be manufactured individually, reducing the difficulty of manufacturing, ensuring structural integrity and precision, and stably realizing the function of water distribution and discharge.

[0023] In this embodiment, the number of first water outlets 71 is less than the number of second water outlets 82, and the diameter of the first water outlets 71 is larger than the diameter of the second water outlets 82. The first water outlets 71 and the second water outlets 82 are arranged in a dot matrix pattern on the water outlet member 2, and both are formed so that their diameters gradually decrease along the direction of water flow discharge.

[0024] Referring to Figures 10 and 11, the decorative housing 3 is a hollow structure with open ends and includes a front case 31 and a rear case 32. Both the front case 31 and the rear case 32 are inserted into and attached to the main body member 1, and the two are fixedly connected by a snap engagement structure. This facilitates the installation of the decorative housing 3. The front case 31 is provided with fitting holes 33 for exposing the discharge ports of the second and third water outlet passages 61 and 62 of the water outlet member 2 to the outside, thereby enhancing the visual unity between the decorative housing 3 and the water outlet member 2 and improving the harmony and aesthetics of the product appearance.

[0025] Furthermore, as shown in Figure 11, a flow guide head 9 is engaged and fixed to the decorative housing 3, thereby improving the connection stability between the front case 31 and the rear case 32. The flow guide head 9 is provided with a cleaning hole 91, which communicates with the first water outlet passage 51. The cleaning hole 91 is also positioned to be inclined toward the rear case 32 with respect to the central axis of the first water outlet passage 51, allowing the water flow in the first water outlet passage 51 to be discharged at an angle. This reduces the risk of the discharged water flow falling into the cleaning hole 91 and obstructing normal water discharge when the shower is used from below to above.
