[0038] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0039] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0042] like Figures 1 to 11 As shown, the present invention provides a water outlet device, which includes a water outlet head 3 and a clamping and fixing mechanism. The clamping and fixing mechanism includes a clamping assembly 1 and a driving assembly 2. The clamping assembly 1 includes a fixing seat 11, a retaining member 12, and a clamping member 13. The retaining member 12 is fixed to the fixing seat 11, and the water outlet head 3 is connected to the retaining member 12; the clamping member 13 moves on the fixing seat 11; the driving assembly 2 includes a driving member 21, which rotates on the fixing seat 11 and can drive the clamping member 13 to move closer to or away from the retaining member 12;

[0043] The fixing seat 11 has an arc-shaped end surface 111, and the driving member 21 has a first arc-shaped protrusion 22. The first arc-shaped protrusion 22 abuts against the arc-shaped end surface 111. When the driving member 21 rotates relative to the fixing seat 11, the first arc-shaped protrusion 22 can move between the starting point 112 and the end point 113 of the arc-shaped end surface 111 to drive the clamping member 13 to approach or move away from the retaining member 12; when the clamping member 13 moves away from the retaining member 12 and releases the external component 5, the clamping assembly 1 is in a first position on the same straight line as the driving assembly 2; and when the clamping member 13 approaches the retaining member 12 and clamps the external component 5, the clamping assembly 1 is in a second position set at an angle to the driving assembly 2.

[0044] The above-mentioned water outlet device can clamp the external component 5 (such as a shower rod) together through the retaining member 12 and the clamping member 13, so as to facilitate the water head 3 to be fixed at any position of the external component 5, and at this time the clamping component 1 and the driving component 2 are located in the second position set at an angle, and the water head 3 is fixed on the shower rod for use as a waist spray; and when switching the use state, it is only necessary to move the first arc-shaped protrusion 22 of the driving member 21 on the arc-shaped end surface 111, so that the clamping member 13 is away from the retaining member 12, and the external component 5 is released. At this time, the clamping component 1 and the driving component 2 are located in the first position in the same straight line state, which is convenient for holding and used as a hand-held shower; thus, through the adjustment of a driving component 2, the mutual conversion between the clamping state of the waist spray and the loosening state of the hand-held shower is realized, making the conversion more convenient, minimizing the adjustment time as much as possible, and improving the use experience.

[0045] Furthermore, by directly clamping the external component 5 with the retaining member 12 and the clamping member 13, it can replace the existing showerhead mounting, making the overall structure more concise and aesthetically pleasing. This also reduces costs, and when adjusting the fixed position, there is no need to adjust the showerhead mounting, saving adjustment time. It should be noted that the water outlet 3 adopts a rod-shaped outlet, making it convenient for use as a waist shower. The specific structure is not limited here. Furthermore, this water outlet device can also be used for kitchen faucet showers.

[0046] In some embodiments, there is a critical point between the starting point 112 and the end point 113. After the first arc-shaped protrusion 22 passes the critical point, the first arc-shaped protrusion 22 can automatically move to the starting point 112 or the end point 113; therefore, when the first arc-shaped protrusion 22 crosses the critical point, there is no need to apply force, and the first arc-shaped protrusion 22 can automatically move to the starting point 112 or the end point 113, making state adjustment more labor-saving and convenient.

[0047] like Figure 5 、 Figure 8 and Figure 10As shown, in some embodiments, the driving member 21 of the clamping and fixing mechanism includes a first shaft 211 and a second shaft 212, wherein one end of the second shaft 212 is connected to the first shaft 211, and the second end of the second shaft 212 extends in a direction away from the first shaft 211, so that the first shaft 211 and the second shaft 212 are arranged at an angle. The fixing base 11 has an axial hole 114, and the first shaft 211 is inserted into the axial hole 114, so that the first shaft 211 can rotate in the axial hole 114. To facilitate installation, the axial hole 114 passes through the fixing base 11 in a direction perpendicular to the axis of the first shaft 211 to form an installation opening on the fixing base 11. In other words, the axial hole 114 in the current embodiment is U-shaped, which is convenient for installing the first shaft 211 while being able to support the first shaft 211. A notch is also provided below the fixing base 11 to facilitate the movement of the second shaft 212, and then, driven by the second shaft 212, the first shaft 211 rotates relative to the fixing base 11. In the current embodiment, the arcuate end surface 111 is disposed on the mounting opening of the fixing base 11 away from the shaft hole 114. Furthermore, the first arcuate protrusion 22 is elastically disposed on the second shaft 212 so that the first arcuate protrusion 22 continuously abuts against the arcuate end surface 111 during movement of the second shaft 212.

[0048] In order to enable the second shaft 212 to drive the clamping member 13 to move closer to or away from the holding member 12 during the rotation process, as shown in FIG. Figure 6 As shown, in some embodiments, the clamping member 13 includes a guide column 131 and a clamping head 132, wherein the clamping head 132 is provided at one end of the guide column 131, and a blocking portion 133 is provided at the other end of the guide column 131, and a second arc-shaped protrusion 213 is provided on the first shaft 211, so that when the first shaft 211 rotates, the second arc-shaped protrusion 213 can be driven to abut against the blocking portion 133, so that the guide column 131 drives the clamping member 13 away from the retaining member 12, so that the clamping head 132 and the retaining member 12 can release the external component 5; and when the first shaft 211 rotates in the opposite direction, the second arc-shaped protrusion 213 can be driven to disengage from the blocking portion 133, at which time the blocking portion 133 disengages from the abutment restriction of the second arc-shaped protrusion 213, and the clamping member 13 can be driven close to the retaining member 12, and the clamping head 132 and the retaining member 12 can clamp the external component 5 together. Further, as Figure 6 and Figure 9As shown, when the blocking portion 133 is released from the abutment restriction of the second arc-shaped protrusion 213, in order to enable the clamping head 132 to automatically approach the retaining member 12, a second elastic member 14 is provided between the clamping head 132 and the fixing seat 11. The second elastic member 14 has a tendency to keep the clamping head 132 close to the retaining member 12. In other words, when the second arc-shaped protrusion 213 abuts the blocking portion 133, the clamping head compresses the second elastic member 14 to accumulate potential energy. When the blocking portion 133 is released from the abutment restriction of the second arc-shaped protrusion 213, the second elastic member 14 drives the clamping head 132 to approach the retaining member 12, so that the clamping head 132 and the retaining member 12 continue to clamp the external component 5.

[0049] For example, the second elastic member 14 is a compression spring that is sleeved on the guide post 131. One end of the compression spring abuts against the clamping head 132, and the other end abuts against the fixed seat 11. To facilitate abutment on one side of the fixed seat 11 and increase the abutment area, an abutment disk 16 is sleeved on the guide post 131. The clamping head 132 and the abutment disk 16 jointly clamp the compression spring.

[0050] like Figure 8 and Figure 9 As shown, in some embodiments, to ensure the stability of the guide post 131 during movement, a guide slot 115 is provided on the fixing base 11. The guide slot 115 extends through the fixing base 11 in the direction in which the clamping member 13 approaches or moves away from the retaining member 12, and the guide post 131 moves within the guide slot 115. Furthermore, the outer side of the guide post 131 has rectangular corners, and the guide slot 115 is also rectangular. This prevents the guide post 131 from rotating when sliding within the guide slot 115.

[0051] In some embodiments, in order to reduce the overall volume and make the clamping and fixing mechanism more compact, the guide column 131 is provided with a movable groove 134 along its axial direction, and the first shaft 211 is inserted into the movable groove 134, thereby reducing the occupied volume as much as possible while reducing the interference between the two.

[0052] Based on the first arc-shaped protrusion 22 being arranged on the second shaft 212, the second arc-shaped protrusion 213 is located on the first shaft 211. Figure 5 and Figure 8 As shown, in the current embodiment, the first shaft 211 and the second shaft 212 are arranged perpendicularly. When the second arc-shaped protrusion 213 on the first shaft 211 hits the blocking portion 133 on the guide column 131, the second shaft 212 and the guide column 131 are collinear. At this time, the first arc-shaped protrusion 22 is located at the starting point 112 of the arc-shaped end surface 111. When the second arc-shaped protrusion 213 on the first shaft 211 is completely separated from the blocking portion 133, the second shaft 212 is perpendicular to the guide column 131, as shown in FIG. Figure 5 and Figure 8As shown, at this time, the first arc-shaped protrusion 22 is located at the end point 113 of the arc-shaped end surface 111, and the critical point is located between the starting point 112 and the end point 113 of the arc-shaped end surface 111; and the distance between the axis of the second axis 212 and the arc-shaped end surface 111 gradually increases from the starting point 112 to the critical point, and then gradually decreases from the critical point to the end point 113, so that the arc-shaped end surface 111 is an elliptical end surface. In some embodiments, such as Figure 6 As shown, a sliding bushing 23 is slidably connected to the second shaft 212, and a limit member 27 is also provided on the second shaft 212. A first elastic member 24 is clamped between the sliding bushing 23 and the limit member 27. The first arc-shaped protrusion 22 is arranged on the side of the sliding bushing 23 away from the first elastic member 24. The first elastic member 24 can enable the first arc-shaped protrusion 22 to maintain a tendency to press against the arc-shaped end surface 111.

[0053] Furthermore, by providing the first elastic member 24, it is assumed that the first arc-shaped protrusion 22 is located at the starting point 112 of the arc-shaped end surface 111 in the initial state. Figure 7 As shown, the second arc-shaped protrusion 213 presses against the blocking portion 133, the second elastic member 14 is compressed, the clamping head 132 moves away from the retaining member 12, the clamping member 13 and the retaining member 12 are at the maximum distance, and the clamping assembly 1 and the driving assembly 2 are in the first position of the straight line state; when force is applied to the second shaft 212 to rotate, so that the first arc-shaped protrusion 22 moves from the starting point 112 to the critical point to the end point 113, the second arc-shaped protrusion 213 gradually breaks away from the blocking portion 133, the second elastic member 14 is released, and the clamping head 132 approaches the retaining member 12 to clamp the external component 5. In this process, since the distance between the axis of the second shaft 212 and the arc end face 111 gradually increases from the starting point 112 to the critical point, the first elastic member 24 will be compressed; when force is applied After crossing the critical point, the force is withdrawn. At this time, as the distance between the axis of the second shaft 212 and the arc-shaped end surface 111 gradually decreases from the critical point to the end point 113, the first elastic member 24 is released. Based on the point contact between the first arc-shaped protrusion 22 and the arc-shaped end surface 111, the first arc-shaped protrusion 22 moves from the critical point to the end point 113 under the action of the potential energy released by the first elastic member 24, achieving automatic movement, thereby causing the retaining member 12 and the clamping member 13 to jointly clamp the external component 5, and the clamping assembly 1 and the driving assembly 2 to shift to the second position set at the angle; vice versa (the process of the first arc-shaped protrusion moving from the end point 113 to the starting point 112, that is, the process of the clamping head 132 moving away from the retaining member 12 to clamp the external component 5), which will not be repeated. In other alternative embodiments, the first arc-shaped protrusion 22 can also be elastic itself.

[0054] like Figure 2 As shown, since the water outlet head 3 is connected to the retaining member 12, the water outlet head 3 needs to be connected to the water pipe when in use. In order to facilitate the connection of the water pipe and reduce interference, as shown in FIG. Figure 10As shown, in some embodiments, the retaining member 12 is provided with a water outlet 121, which is provided on the side of the retaining member 12 facing away from the clamping member 13. When the water outlet head 3 is connected to the retaining member 12, the water outlet 121 is connected to the inlet of the water outlet head 3. The connection method between the water outlet head 3 and the retaining member 12 is not limited. The water inlet 26 is provided on the driving member 21. Specifically, the water inlet 26 is provided at the end of the second shaft 212 away from the first shaft 211. The water inlet pipe is connected to the second shaft 212, and the water inlet 26 is connected to the water outlet 121. Therefore, after the water pipe is connected, the fixing operation can also be performed.

[0055] Specifically, if Figure 10 As shown, the clamping assembly 1 also includes a connecting pipe 15, the first end of which is closed and connected to the fixing seat 11. In the current embodiment, the first end of the connecting pipe 15 is connected to the fixing seat 11 by a screw or bolt; the second end of the connecting pipe 15 is connected to the retaining member 12, and the connecting pipe 15 is connected to the water outlet 121 on the retaining member 12; the connecting pipe 15 is also provided with a plug port 151, and the first shaft 211 passes through the fixing seat 11 and is plugged into the plug port 151; the first shaft 211 can rotate in the plug port 151; in order to ensure sealing, a sealing ring can also be provided between the second shaft 212 and the connecting pipe 15. A water channel is provided in the first shaft 211 and the second shaft 212, one end of the water channel is connected to the water inlet 26, and the other end passes through the first shaft 211 and is inserted into one end of the plug interface 151, so that the water channel connects the water inlet 26 and the plug interface 151. When supplying water, the water flow can enter the connecting pipe 15 from the water inlet 26 through the water channel, and is transported by the connecting pipe 15 to the water outlet 121 and then enters the water outlet head 3 to discharge water.

[0056] like Figure 4 As shown, in some embodiments, a protective cover 25 is sleeved and fixed on the second shaft 212. The protective cover 25 is arranged on the outside of the first elastic member 24, thereby protecting the first elastic member 24 and reducing the possibility of interference with the first elastic member 24. Exemplarily, the first elastic member 24 is a spring, which is sleeved on the second shaft 212.

[0057] Similarly, if Figure 2 and Figure 11 As shown, the clamping and fixing mechanism also includes a shell 4, which has an inner cavity. The shell 4 is fixed on the fixing seat 11 and covers the second elastic member 14, the clamping member 13, the retaining member 12 and the connecting pipe 15. A placement port 41 is provided on the shell 4 between the clamping member 13 and the retaining member 12 to place the external component 5. An operating port 42 can be provided on one side of the corresponding arc-shaped end face 111 to facilitate the operation of the second shaft 212.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
