Description

Technical Field

[0001] This utility model relates to a multi-button water outlet switching structure. Background Technology

[0002] In modern bathroom fixtures, showerheads, overhead showers, and other shower devices are widely popular due to their multi-functional water flow modes. These devices are typically equipped with various water flow modes to meet different user needs. However, most existing water flow switching mechanisms use a sequential switching method, requiring users to switch water flow modes one by one in a preset order. This design is sufficient when there are fewer functions, but when the number of functions increases to three or more, users need to press the switch button multiple times to return to a specific function, completing one or more cycles. This method is not only cumbersome but also fails to achieve precise function switching, seriously affecting the user experience and ease of operation. Furthermore, traditional switching mechanisms often rely on a single control element, lacking the ability to independently control each water flow function, making it difficult for users to quickly locate the desired water flow mode in actual use. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a multi-button water outlet switching structure.

[0004] This utility model is achieved through the following technical solution:

[0005] A multi-button water outlet switching structure includes: a body having a connected inlet and a water distribution chamber, and at least two outlets and a water outlet channel, with each outlet corresponding to one of the outlets; the outlets being configured to connect the water distribution chamber and the water outlet channel; a central plug, each central plug capable of blocking a corresponding outlet, and the central plug being movable when pressed to allow water from the water distribution chamber to flow through the outlet to the water outlet channel; a sliding block, configured to be driven by the central plug to move within the water distribution chamber, the sliding block having a locking interface configured to lock a protrusion on the central plug to open the outlet for water flow; and a spring disposed between the sliding block and the body, the spring being configured to drive the sliding block to move toward the opening of the locking interface.

[0006] In this embodiment of the utility model, the main body includes a water distribution chamber and a water outlet that can be vertically distributed, a partition is disposed between the water distribution chamber and the water outlet, and the water outlet is arranged in a ring on the partition.

[0007] In this embodiment of the utility model, a settling groove is provided on the side wall of the water distribution chamber, one end of the spring is disposed in the settling groove, and the other end of the spring is disposed on the sliding block; the vertical movement of the central bolt in the water distribution chamber can drive the sliding block to move laterally in the water distribution chamber, and the lateral movement of the sliding block can cause the protrusion to disengage from the card interface.

[0008] In this embodiment of the present invention, a reset spring is provided between each of the above-mentioned central plugs and the water distribution chamber. When the protrusion disengages from the card interface, the reset spring can drive the central plug to reset, thereby blocking the corresponding water outlet and preventing the water flow in the water distribution chamber from flowing from the water outlet to the corresponding water outlet channel.

[0009] In this embodiment of the utility model, the number of locking interfaces on the sliding block can be adapted to the number of protrusions on the central bolt. The sliding block is also provided with a first inclined surface. The vertical movement of the protrusion as the central bolt is pressed can abut against the first inclined surface to drive the sliding block to move laterally. When the protrusion moves vertically to the locking interface, the spring drives the sliding block to return to its horizontal position, so as to realize the locking engagement between the locking interface and the protrusion.

[0010] In this embodiment of the utility model, the sliding block is further provided with a second inclined surface, and the locking interface is located between the first inclined surface and the second inclined surface. When the protrusion engages with the locking interface, the protrusion can abut against the second inclined surface as the central bolt continues to be pressed and moves vertically, thereby driving the sliding block to move laterally. The remaining unpressed central bolts can be reset under the action of the spring. After the pressure is released from the central bolt that was pressed, its protrusion can continue to engage with the locking interface.

[0011] In this embodiment of the utility model, the card interface is arranged horizontally on the sliding block, the central bolt is distributed in a ring on the body, and the protrusion of the central bolt is set towards the sliding block.

[0012] In this embodiment of the utility model, the central plug is located in the water distribution chamber and is equipped with a sealing ring. The sealing ring can seal the water outlet to keep the water outlet in a closed state, and the sealing ring can allow the water outlet to flow when it is not sealed to the water outlet.

[0013] In this embodiment of the utility model, the main body includes an upper shell and a lower shell, the partition is disposed between the upper shell and the lower shell, the water distribution cavity is formed between the upper shell and the partition, and the water outlet is formed between the lower shell and the partition.

[0014] In this embodiment of the utility model, the lower housing is provided with a connecting hole for the center plug to extend out. The connecting hole is coaxially arranged with the water outlet. A sealing element adapted to the center plug is provided at the connecting hole. The sealing ring ensures that the water flowing out of the water outlet can only flow out from the corresponding water outlet channel.

[0015] This utility model discloses a multi-button water outlet switching structure, which has the following beneficial effects: The structure enables precise function switching; users can directly switch the water flow function to the desired function in one go, avoiding the multiple switching required by traditional methods and improving the convenience of showering. Specifically: First, the design of multiple center valves allows users to directly select the desired water flow function, avoiding the cumbersome operation of traditional sequential switching; second, the mechanical linkage between the sliding block and the center valves ensures the accuracy and stability of water flow switching; finally, the cooperation between the sealing ring and the connecting hole reduces the possibility of water leakage, improving the overall reliability and service life of the device.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0032] Referring to the accompanying drawings, the multi-button switching water outlet structure of this utility model includes a main body 100, a central plug 10, a sliding block 20, and springs, among other main components. The main body 100 is the core load-bearing component of the entire device, internally comprising a water distribution chamber 101 and a water outlet channel 102, separated by a partition 110. One end of the water distribution chamber 102 has an inlet 103 for introducing external water; the water outlet channel 102 corresponds one-to-one with at least two outlets 104, each outlet 104 connecting the water distribution chamber 101 to its corresponding outlet channel 102. The lower housing 130 of the main body 100 has a connection hole 131 for the central plug 10 to extend and interact with the user, primarily via a button connection. Specifically:

[0033] A multi-button water outlet switching structure includes: a main body 100, which is equipped with a connected inlet 103 and a water distribution chamber 101. The main body is also equipped with at least two outlets 104 and water outlet channels 102. In the embodiment shown in the attached drawings, an embodiment with three outlets is depicted, that is, it simultaneously has three water outlet channels, three outlets, and three center plugs. The water outlet channels correspond one-to-one with the outlets. The outlets are configured to connect the water distribution chamber and the water outlet channels. Each water outlet channel is a flow channel for a specific function of water outlet; a center plug 10, each of which can block the corresponding outlet. The center plug is configured to move when pressed, so that the water in the water distribution chamber flows through the outlet to the water outlet channel. In the normal state, each center plug will block the corresponding outlet. The outlet is blocked and no water flows out. Water can only flow out after pressing and moving it vertically. A sliding block 20 is configured to be driven by the central bolt to move within the water distribution chamber. The sliding block is equipped with a locking interface 21, which is configured to lock the protrusion 11 on the central bolt, thus opening the outlet for water flow. When the central bolt is pressed, it drives the sliding block to move laterally, thereby opening the water flow at the outlet. Simultaneously, the protrusion is locked within the locking interface to keep the water flow at the outlet open. A spring 22 is configured between the sliding block and the body. The spring is configured to drive the sliding block to move towards the opening of the locking interface. When the protrusion is beside the locking interface, the spring drives the locking interface to engage the protrusion.

[0034] In one use, the body includes a vertically distributed water distribution chamber 101 and a water outlet 102, with a partition 110 disposed between the water distribution chamber and the water outlet, and the water outlet is annularly disposed on the partition.

[0035] Preferably, a recess 105 is provided on the side wall of the water distribution chamber. One end of the spring is disposed in the recess, and the other end of the spring is disposed on the sliding block. The vertical movement of the central bolt in the water distribution chamber can drive the sliding block to move laterally within the water distribution chamber. The lateral movement of the sliding block can disengage the protrusion from the locking interface. That is, the protrusion of the actively pressed central bolt can be locked into the locking interface, while the other central bolts (whose protrusions are already engaged with the locking interface) can be reset to close the water flow when the sliding block moves laterally, thereby achieving water flow switching. Each of the above-mentioned central bolts is provided with a return spring 12 between itself and the water distribution chamber. When the protrusion disengages from the locking interface, the return spring can drive the central bolt to reset, thereby blocking the corresponding outlet and preventing the water flow in the water distribution chamber from flowing from that outlet to the corresponding outlet channel.

[0036] In one embodiment, the number of locking interfaces on the sliding block can be adapted to the number of protrusions on the central plug. The sliding block is also provided with a first inclined surface 23. The vertical movement of the protrusion as the central plug is pressed can abut against the first inclined surface to drive the sliding block to move laterally. When the protrusion moves vertically to the locking interface, the spring drives the sliding block to return to its horizontal position, so as to realize the locking engagement between the locking interface and the protrusion, that is, the water outlet corresponding to the pressed central plug remains in the water outlet state. The sliding block is also provided with a second inclined surface 24. The locking interface is located between the first and second inclined surfaces. When the protrusion engages with the locking interface, the protrusion, as the central plug continues to be pressed, moves vertically and abuts against the second inclined surface, thereby driving the sliding block to move laterally. The remaining unpressed central plugs can be reset under the action of the spring. After the pressure on the continued-pressed central plug is released, its protrusion can continue to engage with the locking interface. In this utility model, combined water discharge can be achieved, that is, the protrusions of at least two central plugs engage with the locking interface. When the protrusions of all central plugs are engaged, the second inclined surface can play a role in switching. As long as one central plug continues to be pressed, the remaining central plugs reset, and the pressed central plug retains the water flow of the corresponding outlet. The locking interfaces are arranged laterally on the sliding block, and the central plugs are distributed in a ring on the body, with the protrusions of the central plugs facing the sliding block. Of course, a corresponding inclined surface can also be provided in the direction in which the protrusion is pressed and moved.

[0037] Meanwhile, the central plug is equipped with a sealing ring 13 located in the water distribution chamber. The sealing ring can seal the water outlet to keep the water outlet in a closed state, and the sealing ring can keep the water outlet in a flowing state when it does not seal the water outlet. In other words, the sealing ring is used to determine whether the water outlet is in a flowing or closed state.

[0038] Preferably, the main body includes an upper shell 120 and a lower shell 130. The partition is disposed between the upper shell and the lower shell, forming the water distribution chamber between the upper shell and the partition, and forming a water outlet channel between the lower shell and the partition. The lower shell is provided with a connecting hole 131 for the center plug to extend out. The connecting hole is coaxially arranged with the water outlet, and a sealing element 14 adapted to the center plug is disposed at the connecting hole. This sealing ring ensures that the water flowing out of the water outlet can only flow out through the corresponding water outlet channel.

[0039] This invention has a wide range of practical applications, especially in shower devices such as showerheads and overhead showers. Traditional shower devices typically use a sequential switching method, requiring users to press buttons one by one to find the desired function, which is cumbersome and inefficient. In contrast, the multi-button switching design of this invention allows users to directly select the target function without multiple attempts, greatly improving ease of use. Furthermore, by optimizing the fit between the sealing ring and the sealing element, this invention effectively reduces the possibility of water leakage and extends the service life of the device.

[0040] In summary, this invention achieves precise and efficient water flow control through a multi-button switching structure, significantly improving the user experience. Its unique sliding block and center bolt linkage mechanism ensures operational reliability and stability, while the double-sloping surface design further expands its functional range. Whether in a home bathroom or a public bathing facility, this invention can meet diverse needs, providing users with a more comfortable and convenient showering experience.

As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge.
