Description

Technical Field

[0001] This invention relates to a small waterway switching structure. Background Technology

[0002] Existing water systems often require flow diversion, such as to meet different water spray needs of the showerhead or to switch between a handheld showerhead and an overhead showerhead. This is done by rotating or pushing a knob to actually divert the water flow, which is inconvenient. At the same time, these switching components take up a lot of space, which results in a large size of the showerhead and other water outlet parts. Moreover, the current switching components are basically shaped like ballpoint pens, which make a "clicking" sound when switching, failing to provide a good user experience. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention aims to provide a small-scale waterway switching structure.

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

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," 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. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] Referring to the accompanying drawings, a small water channel switching structure includes a main body 100, on which are provided a water inlet channel 11, a water distribution chamber 12, and at least two water outlet channels 13 that can cooperate with each other. Referring to the accompanying drawings, the embodiment shown in the drawings has two water outlet channels. After water flows into the water distribution chamber from the water inlet channel, it undergoes water distribution processing, allowing water to exit from the two water outlet channels separately or simultaneously. It also includes a switching plate 20, which is disposed within the water distribution chamber. The switching plate can move axially and radially within the water distribution chamber, and can move up and down and rotate within the water distribution chamber. The switching plate can open and close the water inlet of the water outlet channel. When the switching plate and the water inlet 131 of the water outlet channel are blocked, the water inlet is closed. The blocked water outlet will not discharge water. When the notch 21 of the switching plate aligns with the inlet of the water outlet, water can flow through the outlet. The switching plate is provided with guide posts 22 on its periphery. Referring to the attached drawings, preferably, four guide posts are provided, evenly distributed on the periphery of the switching plate. A first guide slope 121 is located on the periphery of the switching plate, and the guide posts can be connected to the first guide slope. A second guide slope 122 is located on the periphery of the switching plate, and the guide posts can be connected to the second guide slope. A spring 30 is connected to the body and the switching plate. The cooperation between the guide posts and the first and second guide slopes can drive the switching plate to rotate.

[0033] In one application of this invention, four first and four second guide ramps are provided, corresponding to the number of guide posts, and are distributed around the periphery of the switching disk. The initial position P1 of the guide post is between two adjacent first guide ramps, which is also the initial state during switching. At this time, simply pressing the connecting rod to move it downwards will cause the switching disk to move downwards as well, and the guide post will also move downwards along the side wall of the first guide ramp. In this state, the spring is compressed. When the guide post moves downwards and engages with the second guide ramp, pressing the connecting rod further will cause the switching disk to rotate and move downwards simultaneously under the action of the guide post contacting and engaging with the second guide ramp. This position is P2. The guide column continues to rotate until it aligns with the first guide ramp in the axial direction. At this point, the connecting rod is released, and the switching disc rises under the action of the spring, causing the guide column to contact and engage with the first guide ramp. This position is P3. The spring then continues to return to its original position, and the guide column moves up and rotates along the first guide ramp until it reaches another water outlet position P1. This completes one switching operation. Preferably, a sealing soft rubber 50 that engages with the switching disc is provided at the water inlet of the outlet channel to ensure that no water leakage occurs after switching. During this process, the guide column rotates along the first and second guide ramps without producing significant noise, thus improving the user experience.

[0034] Preferably, the initial position can be a sinkhole to accommodate the guide post. When the guide post is in the sinkhole, the switching operation is completed. The axial projections of the first guide slope and the second guide slope partially overlap, so that the guide post can be transferred to the first guide slope after engaging with the second guide slope.

[0035] Preferably, the first guide slope and the second guide slope are disposed on the inner peripheral wall of the water distribution cavity. The first guide slope is disposed above the second guide slope. The first guide slope is an upward inclined slope, and the second guide slope is a downward inclined slope. A protrusion can be formed on the inner peripheral wall of the water distribution cavity with a downward switching plate. The corresponding first guide slope and the second guide slope are disposed on the protrusion. Preferably, the side wall of the first guide slope and the side wall of the other adjacent first guide slope form the above-mentioned initial position, which can also be referred to as a settling tank.

[0036] Based on the above, the axial extension line L of the lowest end of the first guide slope can be located on the second guide slope. In other words, this allows the guide post to be transferred to the first guide slope after engaging with the second guide slope. When the guide post begins to move downward, the side wall of the lowest end of the first guide slope moves downward.

[0037] Preferably, the switching disk is provided with a notch 21. When the notch is engaged with the inlet of the outlet channel, water can pass through the outlet channel. When the notch is engaged with the inlet of the outlet channel, the inlet is not blocked and water can pass through. When the notch is not engaged with the inlet of the outlet channel, the inlet is blocked and water cannot pass through.

[0038] In use, the switching disk of the present invention further includes a connecting rod 23, which can move synchronously with the switching disk. Preferably, the connecting rod is hollow so that it can cooperate with the guide rod described below. One end of the connecting rod is located inside the water distribution cavity and is connected to the switching disk, while the other end of the connecting rod can be located outside the water distribution cavity.

[0039] Preferably, it also includes a button 40, which is connected to the main body and is connected to the other end of the connecting rod to drive the axial movement of the switching disk. Pressing the button drives the connecting rod and the switching disk to move downward.

[0040] Preferably, the present invention also includes a slot 81, which can also be disposed on a connector 80 that can be connected to a button. The slot can be connected to the button, and a locking block 24 is disposed at the other end of the connecting rod. The locking block can be connected to the slot. Preferably, both the slot and the locking block are cross-shaped. During the downward movement of the connecting rod, the slot and the locking block are connected. Since the connecting rod rotates with the switching disk, while the button does not rotate, the locking block can disengage from the slot under the action of a spring when the switching disk rotates. When the switching is completed, the locking block can be locked back into the slot, which can produce a small sound to remind the user that the switching work is completed.

[0041] Furthermore, the present invention also includes a guide rod 60, which is disposed inside the water distribution cavity. The guide rod is connected to the connecting rod, and the spring is sleeved on the outer periphery of the guide rod. The connecting rod can be hollow, so that the connecting rod is sleeved outside the guide rod, which plays a stable guiding role and ensures that it can move up and down and rotate stably.

[0042] More specifically, the present invention includes a main body 100 comprising a water inlet body 110 and a water distribution body 120 connected in a mating manner. The water inlet channel is disposed on the water inlet body, and the water outlet channel is disposed on the water distribution body. The water distribution body can be fastened to the water inlet body to form a water distribution cavity. The first guide slope is disposed on the water distribution body, and the second guide slope is disposed on the water inlet body. The other end of the connecting rod can pass through the water distribution body and be located outside the water distribution cavity. A sealing ring 70 is provided between the connecting rod and the water distribution body to ensure that the water in the water distribution cavity does not flow out of the main body.

[0043] Furthermore, the main body also includes a housing 130, in which the water inlet and water outlet are located. The housing is provided with a mounting hole 131, and the button is disposed in the mounting hole. The side wall of the mounting hole is recessed inward to form a guide groove 132. The button is provided with a connecting block 41 that can cooperate with the guide groove, so as to ensure that the button can move up and down during use without rotating.

[0044] In a preferred embodiment of the present invention: pressing the button drives the switching disc to move downwards, and the guide column rotates at a certain angle under the action of the second guide inclined surface of the water inlet. When the button is released, the switching disc rotates at a certain angle under the action of the spring and the first guide inclined surface of the guide column and the water outlet, and then cooperates with the sealing soft rubber to separate the water and switch.

[0045] The foregoing description illustrates and describes preferred embodiments of the present invention. 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 techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
