[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 accompanying drawings, a pull-out head capable of bidirectional reciprocating water flow includes a water outlet body 10. Multiple water inlets 11 are located on the rear side of the water outlet body. In use, multiple sets of water outlet holes 12 are located on the front side of the water outlet body. Each set of water outlet holes represents a water flow (such as shower water, gentle water, blade water, etc.) and a water path, corresponding to each water inlet. It also includes a water inlet chamber A, which is connected to the water inlets. A rotatable water divider 20 is located within the water inlet chamber. The water divider has water outlets 21, arranged in a set of one or two, corresponding to the corresponding water inlets. Water flows through the water outlets to the corresponding water inlets and then out through the water path and water outlet holes of the water outlet body. This is similar to existing designs and will not be described in detail here. The description includes: the water inlet can connect to different water inlets as the water divider rotates; it also includes a rotating drum 30 that rotates synchronously with the water divider, the rotating drum having a first ratchet set 31 and a second ratchet set 32 ​​arranged axially, the first and second ratchet sets driving in opposite directions, enabling the rotating drum to achieve forward and reverse rotation; it also includes a first button 91 and a second button 92, the first button can engage with the first ratchet set to drive the rotating drum to rotate, and the second button can engage with the second ratchet set to drive the rotating drum to rotate. The first and second buttons adjust the rotation direction of the rotating drum in opposite directions. If the first button can drive the rotating drum to rotate forward, then the second button can drive the rotation to rotate in reverse. At the same time, the first button will not interfere with the reverse rotation of the rotating drum, and the second button will not interfere with the forward rotation of the rotating drum.

[0030] In one embodiment, at least three different water inlets are provided. Taking four types of water splashes as an example, in the prior art, if the current water splash is 1, the switch can only be made to water splashes 2, 3, and 4 in sequence, which means that it takes three switches to switch from water splash 1 to water splash 4. However, the present invention can make a reverse switch, and can switch from water splash 1 to water splash 4 in just one time, thus reducing the number of switches and making the switch faster.

[0031] Preferably, the system also includes an inner body 40, which forms an inlet cavity with the outlet body. The inner body is provided with an inlet channel 41 that communicates with the inlet cavity. Water flows through the inlet channel of the inner body to the inlet cavity and then switches water paths after passing through a water divider. A sealing gasket 25 is provided between the water divider and the rear side of the outlet body. The sealing gasket ensures that the water outlet and the inlet correspond one-to-one, thus preventing water from flowing between different water paths or causing leakage.

[0032] Furthermore, the inner body has a corresponding cavity 43 and a connecting hole 44 in its middle. The connecting hole is located between the water inlet cavity and the cavity. The rotating cylinder is disposed in the cavity. The water distributor is connected to a rotating shaft 22. The rotating shaft and the rotating cylinder can be connected by a keyway. The rotating shaft can rotate synchronously with the water distributor and the rotating cylinder. The rotating shaft is disposed in the connecting hole, and one end of the rotating shaft can extend out of the water inlet cavity through the connecting hole. The water outlet body has a first settling tank 13, and the inner body has a second settling tank 45. The first settling tank, the second settling tank, and the connecting hole are coaxially arranged. The two end faces of the rotating shaft respectively mate with the first settling tank and the second settling tank, forming a bearing-like hole to restrict the rotating shaft. At the same time, the water distributor is located on the outer periphery of the rotating shaft. A sealing ring 23 is provided between the connecting hole and the rotating shaft.

[0033] Furthermore, it also includes a first pawl 93 and a second pawl 94. The first button can drive the rotating drum to rotate through the engagement of the first pawl and the first ratchet gear, and the second button can drive the rotating drum to rotate in the opposite direction through the engagement of the second pawl and the second ratchet gear. The first pawl and the second pawl include an elastic plate 90, one end of which is connected to the inner body. When the first button or the second button is pressed, the other end of the elastic plate can engage with the first ratchet gear and the second ratchet gear to drive the rotation of the rotating drum. When the first button or the second button is not pressed, the other end of the elastic plate can separate from the first ratchet gear and the second ratchet gear, which will not interfere with the normal rotation of the rotating drum and can also reduce noise generation.

[0034] Preferably, the system further includes a first transmission rod 95 and a second transmission rod 96. One end of the first transmission rod is connected to the first button, and the other end of the first transmission rod can abut against the first pawl. When the first button is pressed, the first transmission rod can drive the first pawl to engage with the first ratchet gear. One end of the second transmission rod is connected to the second button, and the other end of the second transmission rod can abut against the second pawl. When the second button is pressed, the second transmission rod can drive the second pawl to engage with the second ratchet gear. The system also includes a first spring 97, a second spring 98, and a connecting piece 14. The first spring is disposed between the connecting piece and the first button, and is sleeved on the outer periphery of the first transmission rod. The second spring is disposed between the connecting piece and the second button, and is sleeved on the outer periphery of the second transmission rod. The connecting piece has a guide hole 15, through which the first and second transmission rods can pass and abut against the first and second pawls. The system also includes a housing 50, within which the water outlet and inner body are located. The connecting piece is connected to the water outlet.

[0035] Refer to the attached diagram in the instruction manual. Figure 6 In another embodiment of this utility model, one end of the first pawl 93 can be fixedly connected to the first button 91, and the other end of the first pawl can be connected to the first ratchet assembly 31. When the first button is pressed, the first pawl can move down synchronously with the first button and drive the rotating drum to rotate. A first spring 97 is provided between the first button and the inner body. The first spring can make the first button and the first pawl reset synchronously. One end of the second pawl 94 can be fixedly connected to the second button 92, and the other end of the second pawl can be connected to the second ratchet assembly 32. When the second button is pressed, the second pawl can move down synchronously with the second button and drive the rotating drum to rotate. A second spring 98 is provided between the second button and the inner body. The second spring can make the second button and the second pawl reset synchronously.

[0036] This utility model discloses a multi-functional pull-out head capable of bidirectional reciprocating water splash switching. The pull-out head can simultaneously display multiple water splashes, which can be switched between by pressing a button, achieved with only two buttons. It allows for forward and reverse cyclic switching between multiple splashes, as well as reciprocating switching between any two splashes. It can accommodate three, four, five, or more splashes without requiring a complete cycle to return to the previous splash, making operation more convenient. The pull-out head uses two buttons for forward and reverse switching, and two sets of ratchet pawls. The ratchet pawls can be fixedly connected to the buttons, thus moving synchronously with them; alternatively, they can be detached from the buttons, with the ratchet pawls moving via a transmission rod when pressed. A rotating drum is also included, equipped with two sets of ratchet teeth in opposite directions. Pressing the button causes the ratchet pawls to contact the ratchet teeth, thereby driving the rotating drum, rotating shaft, and water distributor to rotate synchronously. When released, the pawl resets due to its own elasticity or spring force, preparing for the next press. During reset, the pawl separates from the ratchet assembly. Therefore, when the next press involves a different set of pawls in the opposite direction, the ratchet assembly of the rotating drum will not interfere with the pawl during reverse rotation, ensuring smooth rotation. During water flow, water enters from the inner body and flows into the inlet chamber formed between the inner body and the outlet body. The water divider and the outlet body are sealed by a water-dividing sealing gasket. Water must pass through at least one water passage on the water divider before flowing to one of the inlets of the outlet body, thus creating different water splashes. During switching, one set of pawls drives the rotating drum to rotate clockwise, while another set drives it to rotate counterclockwise, causing the water divider to rotate in different directions, allowing the pull-out head to switch between any two water splashes.

[0037] 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.
