[0038] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0039] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0041] In the description of this embodiment, the orientation or positional relationships such as "up", "down", "left" and "right" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] As Figures 1 to 11 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 holding member 12 and a clamping member 13. The holding member 12 is fixed on the fixing seat 11, and the water outlet head 3 is connected to the holding member 12; the clamping member 13 moves on the fixing seat 11; the driving assembly 2 includes a driving member 21, and the driving member 21 rotates on the fixing seat 11 and can drive the clamping member 13 to approach or move away from the holding member 12;

[0043] The fixing seat 11 has an arc-shaped end face 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 face 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 ending point 113 of the arc-shaped end face 111 to drive the clamping member 13 to approach or move away from the holding member 12; when the clamping member 13 moves away from the holding member 12 and releases the external component 5, the clamping assembly 1 is in a first position collinear with the driving assembly 2; and when the clamping member 13 approaches the holding member 12 and clamps the external component 5, the clamping assembly 1 is in a second position with an included angle with the driving assembly 2.

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

[0045] In addition, by directly clamping the external component 5 by the holding member 12 and the clamping member 13, the original shower head fixing seat can also be replaced, making the overall structure more concise and beautiful; at the same time, the cost can also be reduced; when adjusting the fixing position, there is no need to adjust the shower head fixing seat, saving the adjustment time. It should be noted here that the water outlet head 3 adopts a rod-shaped water outlet head, so as to be convenient for use as a waist spray, and the specific structure is not limited. In addition, this water outlet device can also be used for the faucet shower head in the kitchen.

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

[0047] Such as 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 set at an angle; and the fixing seat 11 has an axial hole 114, and the first shaft 211 is penetrated in the axial hole 114, so that the first shaft 211 can rotate in the axial hole 114; in order to facilitate installation, the axial hole 114 passes through the fixing seat 11 in a direction perpendicular to the axis of the first shaft 211 to form an installation opening on the fixing seat 11. That is, the axial hole 114 in the current embodiment is U-shaped, and it is convenient to install the first shaft 211 when it can support the first shaft 211. A notch is also provided below the fixing seat 11, so that the second shaft 212 can be moved conveniently, and then driven by the second shaft 212, the first shaft 211 rotates relative to the fixing seat 11. In the current embodiment, the arcuate end surface 111 is disposed on the fixing seat 11 at a side of the mounting opening away from the shaft hole 114. In addition, the first arcuate protrusion 22 is elastically disposed on the second shaft 212 so that the first arcuate protrusion 22 can continuously abut against the arcuate end surface 111 during the 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 arranged at one end of the guide column 131, and a blocking portion 133 is arranged at the other end of the guide column 131, and a second arc-shaped protrusion 213 is arranged 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 break away from the blocking portion 133, at which time the blocking portion 133 breaks away from the abutment restriction of the second arc-shaped protrusion 213, and the clamping member 13 can be driven to approach the retaining member 12, and the clamping head 132 and the retaining member 12 clamp the external component 5 together. Further, as Figure 6 and Figure 9As shown, when the blocking portion 133 is disengaged from the abutting restriction of the second arc-shaped protrusion 213, in order to enable the clamping head 132 to automatically approach the holding member 12, a second elastic member 14 is provided between the clamping head 132 and the fixed seat 11. The second elastic member 14 has a tendency to keep the clamping head 132 close to the holding member 12. That is to say, when the second arc-shaped protrusion 213 abuts against the blocking portion 133, the clamping head compresses the second elastic member 14 to store potential energy. When the blocking portion 133 is disengaged from the abutting restriction of the second arc-shaped protrusion 213, the second elastic member 14 drives the clamping head 132 to approach the holding member 12, so that the clamping head 132 and the holding member 12 continue to clamp the external component 5.

[0049] Exemplarily, the second elastic member 14 is a compression spring. The compression spring is sleeved on the guiding column 131. One end of the compression spring abuts against the clamping head 132, and the other end abuts against the fixed seat 11. In order to facilitate the abutting on one side of the fixed seat 11 and increase the abutting area, a contact disk 16 is sleeved on the guiding column 131, and the clamping head 132 and the contact disk 16 jointly clamp the compression spring.

[0050] As Figure 8 and Figure 9 shown, in some embodiments, in order to ensure the stability of the guiding column 131 during movement, a guiding groove 115 is provided on the fixed seat 11. The guiding groove 115 penetrates the fixed seat 11 along the direction in which the clamping member 13 approaches or moves away from the holding member 12. The guiding column 131 moves within the guiding groove 115. Further, the outer side of the guiding column 131 has a rectangular edge, and the guiding groove 115 is also rectangular, so as to prevent the guiding column 131 from rotating when it slides within the guiding groove 115.

[0051] In some embodiments, in order to reduce the overall volume and make the clamping and fixing mechanism more compact as a whole, a moving groove 134 is provided on the guiding column 131 along its axial direction, and the first shaft 211 is inserted into the moving groove 134, so that on the basis of reducing the interference between the two, the occupied volume can be reduced as much as possible.

[0052] Based on the fact that the first arc-shaped protrusion 22 is provided on the second shaft 212 and the second arc-shaped protrusion 213 is located on the first shaft 211, as Figure 5 and Figure 8 shown, in the current embodiment, the first shaft 211 and the second shaft 212 are perpendicularly arranged. When the second arc-shaped protrusion 213 on the first shaft 211 abuts against the blocking portion 133 on the guiding column 131, the second shaft 212 and the guiding 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 face 111. When the second arc-shaped protrusion 213 on the first shaft 211 completely disengages from the blocking portion 133, the second shaft 212 and the guiding column 131 are perpendicular, as 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 face 111, and the critical point is located in the middle of the starting point 112 and the end point 113 of the arc-shaped end face 111; the distance between the axis of the second shaft 212 and the arc-shaped end face 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 face 111 is an elliptical end face. In some embodiments, such as Figure 6 As shown, a sliding bushing 23 is slidably connected to the second shaft 212. A limiting member 27 is also provided on the second shaft 212. A first elastic member 24 is clamped between the sliding bushing 23 and the limiting 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 keep the first arc-shaped protrusion 22 in a tendency to abut against the arc-shaped end face 111.

[0053] Furthermore, by providing the above-mentioned first elastic member 24, it is assumed that in the initial state, the first arc-shaped protrusion 22 is located at the starting point 112 of the arc-shaped end face 111. At this time, as Figure 7 As shown, the second arc-shaped protrusion 213 abuts against the blocking portion 133, the second elastic member 14 is compressed, the clamping head 132 is far away from the holding member 12, the clamping member 13 and the holding member 12 are at the maximum distance, and the clamping assembly 1 and the driving assembly 2 are located at the first position in a straight line state; when a force is applied to rotate the second shaft 212 so that the first arc-shaped protrusion 22 moves from the starting point 112 through the critical point to the end point 113, the second arc-shaped protrusion 213 gradually disengages from the blocking portion 133, the second elastic member 14 is released, and the clamping head 132 approaches the holding member 12 to clamp the external component 5. During this process, since the distance between the axis of the second shaft 212 and the arc-shaped end face 111 gradually increases from the starting point 112 to the critical point, the first elastic member 24 will be compressed; when the force is withdrawn after passing the critical point, at this time, since the distance between the axis of the second shaft 212 and the arc-shaped end face 111 gradually decreases from the critical point to the end point 113, the first elastic member 24 will be released. Based on the point contact between the first arc-shaped protrusion 22 and the arc-shaped end face 111, the first arc-shaped protrusion 22 will move from the critical point to the end point 113 under the action of the potential energy released by the first elastic member 24, realizing automatic movement, so that the holding member 12 and the clamping member 13 jointly clamp the external component 5, and the clamping assembly 1 and the driving assembly 2 are transformed to the second position with an included 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 holding member 12 to clamp the external component 5) will not be elaborated. In some alternative embodiments, the first arc-shaped protrusion 22 can also have elasticity itself.

[0054] As Figure 2 As shown, since the water outlet head 3 is connected to the holding member 12, the water outlet head 3 needs to be connected to a water pipe during use. In order to facilitate the connection of the water pipe and reduce interference, as 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 away from the clamping member 13. When the water outlet head 3 is connected to the retaining member 12, the water outlet 121 is communicated with the inlet of the water outlet head 3, and 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, and the water inlet 26 is specifically 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 communicated with the water outlet 121, so that after the water pipe is connected, the fixing operation can also be performed.

[0055] Specifically, 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 screws or bolts; 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 interface 151, the first shaft 211 passes through the fixing seat 11 and is plugged into the plug interface 151; the first shaft 211 can rotate in the plug interface 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 inside 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 port 151, so that the water channel connects the water inlet 26 and the plug port 151. When supplying water, water can flow from the water inlet 26 through the water channel into the connecting pipe 15, 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, and the protective cover 25 is arranged on the outside of the first elastic member 24, so as to protect the first elastic member 24 and reduce 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 opening 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 opening 42 can be provided on one side corresponding to the arc-shaped end surface 111 to facilitate the operation of the second shaft 212.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
