[0026] 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 utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0027] 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] 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.
[0029] Referring to the attached diagram of the instruction manual, a shower head with a switching structure mainly includes an inner water channel capable of linear movement, thereby achieving direct switching of water flow through linear movement, making the overall structure simpler. Specifically, it may include:
[0030] The device includes a housing 10, within which an inner water channel 20 is configured to move linearly along the length direction A of the housing. The inner water channel can be disposed within a handheld portion 11 of the housing. A push button 14 is disposed on the inner water channel to push it to move linearly relative to the housing. An opening 15 is disposed on the housing to match the movement stroke of the push button. The device also includes a water distribution body 30 disposed within the housing. The water distribution body is provided with at least two water inlets 31 arranged in a straight line on the water distribution body. An outlet 21 is disposed on the inner water channel and is configured to communicate with the maximum two water inlets.
[0031] Since the inner water channel can move axially relative to the handheld part and the water inlet, the aforementioned outer shell length direction A can be either the inner water channel or the axial direction of the handheld part.
[0032] In use, each inlet of the water outlet corresponds to a type of functional water. The water flow from the inlet can pass through the flow channel in the water distribution body to the water outlet panel 12 for water discharge, which is similar to existing technology and will not be described in detail here. At the same time, the water outlet can be connected to one inlet to realize the discharge of one type of functional water; the water outlet can also be connected to two adjacent inlets simultaneously to realize the mixed discharge of two types of functional water.
[0033] To ensure the accuracy of the functional water and prevent water leakage in the overall structure, a connecting plate 22 is provided at the outlet end of the inner water channel. The lower end of the connecting plate can be configured as a plane, and the water outlet is disposed on this plane. The plane configuration allows for end-face sealing between the outlet and the water body. The water inlets are arranged on the upper end face of the water distribution body along the linear movement direction of the inner water channel. The plane can be configured corresponding to the upper end face of the water distribution body. Here, the upper end face of the water distribution body does not necessarily need to be a plane. A groove 32 is provided on the upper end face of the water distribution body located around the water inlet. A sealing element 33 is disposed in the groove. The sealing element is configured to be pressed by the water distribution body and the connecting plate to ensure that the water flow from the outlet can only flow to the inlet. The sealing element and the periphery of the inlet achieve a sealed connection. At the same time, the upper end of the sealing element, through sealing cooperation with the plane (connecting plate), ensures that each water inlet can maintain a sealed state with the plane. Only through the water outlet can the water flow be guided to the corresponding connected water inlet, ensuring that water leakage does not occur.
[0034] The upper surface of the water distribution body is provided with two rows of protruding pillars 36. These two rows of protruding pillars are arranged on both sides of the inlet along the linear movement direction of the inner water channel. A pressure plate 40 is fixedly arranged on the protruding pillars. A guide groove 41 is formed between the lower end of the pressure plate and the upper end of the water distribution body. The connecting plate can be arranged in the guide groove and move linearly within the guide groove. Furthermore, the pressure plate is configured to clamp the sealing element between the water distribution body and the connecting plate. The guide groove also has a limiting function, ensuring that the inner water channel can move linearly, while ensuring the sealing of the outlet and inlet to prevent water leakage.
[0035] To ensure better linear movement of the internal waterway, the mounting and fixing structure of the pressure plate is crucial. Specifically, the protruding column is equipped with a threaded hole 34, and the pressure plate is equipped with a first connecting hole 42 corresponding to the threaded hole. A locking screw 43 is positioned between the first connecting hole and the threaded hole to fix the pressure plate to the water distribution body. A guide post 35 is positioned on the water distribution body between two adjacent protruding columns, and a second connecting hole 44 is positioned on the pressure plate between two adjacent first connecting holes. The guide post can be inserted into the second connecting hole to achieve positioning of the pressure plate and the water distribution body. Before installation, the guide post can be engaged with the second connecting hole for locking. The first and second connecting holes are configured in a straight line, and the protruding column and guide post are also configured in a straight line. In use, at least two of each of the first and second connecting holes are provided.
[0036] To ensure users clearly understand whether the switch is in place, the upper surface of the connecting plate is provided with at least two gear grooves 23, which are arranged along the linear movement direction of the inner water channel. A corresponding groove 16 is provided on the outer casing, containing a cooperating spring 17 and a ball bearing 18. The ball bearing extends into the gear groove under the action of the spring. The movement of the inner water channel causes the ball bearing to retract into the groove after squeezing the spring, thus positioning the ball bearing to disengage from the groove. Each time the ball bearing extends into the gear groove, a sound is produced, which the user can hear (or feel the vibration caused by the impact). This completes the switching of a function, either switching from one function to another, or switching from one function to another, achieving a dual-splash water output effect.
[0037] In one use, this utility model also includes a water inlet channel 50 configured with a water inlet end of the outer shell. The water inlet channel can be configured to be connected to the inner water channel so that the inner water channel can move relative to the water inlet channel and the outer shell. The water inlet channel of the inner water channel is inserted into the inner circumference of the water inlet channel, and a sealing ring 51 is provided between the two to ensure that there is no water leakage when the inner water channel moves. The water inlet channel is also fixedly installed inside the outer shell.
[0038] This utility model can also have a water interruption function, which allows the water to be stopped during showering without having to turn off the temperature control valve, so that the water temperature can be consistent next time, saving water. Specifically, a water passage chamber 24 is provided in the middle of the inner water channel, and a switching device 60 is provided in the water passage chamber. The push button is configured to control the operation of the switching device to switch between the flow of water in the inner water channel and the interruption of water flow. The water passage chamber is used to determine whether water is flowing through it.
[0039] In one embodiment, the switching device includes a spindle 61, a first spring 62, a rotor 63, and a second spring 64. The first spring is disposed between the spindle and the water passage cavity, enabling the spindle to reset after each press. The second spring is disposed between the rotor and the water passage cavity, similarly enabling the rotor to reset after each press. The reset of the spindle and rotor is only relative to their axial directions. The spindle can only move axially along its own axis, while the rotor can rotate around its own axis. One end of the spindle extends out of the water passage cavity and is configured to connect to a push button. Thus, the push button can... The device allows for two-way operation: one press switches to pause the water flow, while the other pushes to move the inner water channel in a straight line, switching the water flow function. The spindle is equipped with a first ratchet 65 facing the rotor, and the rotor is equipped with a second ratchet 66. The first ratchet can engage with the second ratchet. The push button is designed to be pressed to rotate the rotor within the water passage cavity, similar to the structure of a ballpoint pen switch, and will not be described in detail here. The water passage cavity is equipped with an inlet hole 25 and an outlet hole 26, and the rotor is equipped with a baffle plate 27 that can block the inlet hole and / or the outlet hole.
[0040] When the switching device is in use, pressing the push button once will cause the rotor to rotate 90° in the water passage chamber, causing the baffle plate to block the water outlet and / or the water outlet, thus making the water flow in the water passage chamber different. The water inlet and the water outlet are preferably located on the same straight line. Pressing the push button again will cause the rotor to rotate another 90°. At this time, the baffle plate will turn away from the water outlet and / or the water outlet, allowing water to flow in the water passage chamber.
[0041] More specifically, this utility model involves pushing a push button, which causes the inner water channel to move linearly. The inner water channel and the water distribution body are tightly fitted together, and the end face is sealed by a sealing element. The inner water channel is designed with an outlet, and the water distribution body is designed with several inlets. The edges of the inlets are designed to be sealed with a soft rubber sealing element. At the same time, a ball is used to control the position of the inner water channel's forward movement, achieving precise switching of the functional water.
[0042] 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 related technical or knowledge. 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.
