[0046] 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.

[0047] like Figures 1 to 14As shown, the present application provides a liquid discharge device, which includes a liquid discharge head 5 and a fixing mechanism, and the fixing mechanism includes a clamping assembly 1 and a driving assembly 2, the clamping assembly 1 includes a clamping member 12 and a retaining member 11, the driving assembly 2 includes a driving member 21, the driving member 21 is connected to the clamping member 12, the liquid discharge head 5 is connected to the retaining member 11, the driving member 21 has a first position and a second position, when the driving member 21 is in the first position, the clamping member 12 is in a first state away from the retaining member 11; when the driving member 21 is in the second position, the clamping member 12 is in a second state close to the retaining member 11, the driving member 21 can be switched between the first position and the second position to drive the clamping member 12 to switch between the first state and the second state; when the clamping member 12 is away from the retaining member 11, the two can release the external part 6, at this time, the clamping assembly 1 is in a third position on the same line as the driving assembly 2; when the clamping member 12 is close to the retaining member 11, the two can clamp the external part 6, at this time, the clamping assembly 1 is in a fourth position set at an angle to the driving assembly 2.

[0048] The above-mentioned liquid outlet device can clamp the external component 6 (such as a shower rod) together through the retaining member 11 and the clamping member 12, so as to facilitate the liquid outlet head 5 to be fixed at any position of the external component 6, and at this time the clamping component 1 and the driving component 2 are in the fourth position set at an angle. At this time, the liquid outlet device is fixed on the shower rod for use as a waist spray, and when switching the use state, it is only necessary to drive the driving member 21 from the second position to the first position, so that the clamping component 1 is changed to the third position in the same line with the driving member 2, so that it is convenient to hold and use as a handheld shower; thereby, by adjusting the position of a driving member 21, the clamping and fixing of the waist spray and the hand-held switching of the handheld shower are realized, making the switching more convenient, minimizing the adjustment time as much as possible, and improving the use experience.

[0049] In addition, by directly clamping the external component 6 through the retaining member 11 and the clamping member 12, it can also replace the original shower head fixing seat, making the overall structure more simple and beautiful; at the same time, it can also reduce costs; when adjusting the fixed position, there is no need to adjust the shower head fixing seat, saving adjustment time.

[0050] It should be noted here that the liquid outlet head 5 adopts a rod-type water outlet head, so that it is convenient to use as a waist sprayer. The specific structure is not limited. The liquid outlet device can also be used for a kitchen faucet shower, which is not specifically limited.

[0051] In some embodiments, the driving member 21 also includes a critical position located between the first position and the second position. After the driving member 21 passes the critical position, the driving member 21 can automatically move to the first position or the second position; thus, when the driving member 21 passes the critical position, no force is required, making the state adjustment more labor-saving and convenient.

[0052] like Figure 4 As shown, in some embodiments, the driving assembly 2 further includes a linkage portion 22, and the driving member 21 is connected to the clamping member 12 via the linkage portion 22. The linkage portion 22 enables the driving member 21 to automatically move to the first position or the second position after passing the critical position.

[0053] Specifically, if Figure 3 and Figure 11 As shown, the fixing mechanism includes a housing 3, which serves as a mounting base. The housing 3 has an inner cavity, and a placement notch 33 is provided on the side wall of the housing 3. The clamping member 12 and the retaining member 11 are located on both sides of the placement notch 33. The external component 6 is placed in the placement notch 33, and then the clamping member 12 is clamped or released in the process of approaching or moving away from the retaining member 11 along the axial direction of the housing 3. The housing 3 is also provided with an operating port 34, through which the driving member 21 extends into the housing 3. Figure 4 and Figure 12 As shown, one of the housing 3 and the driver 21 is provided with an adapter post 35, and the other is provided with an adapter hole 212. The adapter post 35 is connected to the adapter hole 212, allowing the driver 21 to rotate relative to the housing 3 through the adapter post 35 and the adapter hole 212, so that the driver 21 forms a drive adapter point 23 on the housing 3. In the current embodiment, the adapter hole 212 is provided on the driver 21, and the adapter post 35 is provided on the housing 3. Specifically, the adapter post 35 can be provided separately from the housing 3, and the housing 3 is provided with an insertion hole. The adapter post 35 can be a bolt post that inserts into the insertion hole, thereby facilitating installation. In some alternative embodiments, the adapter post 35 can also be integrally formed with the housing 3.

[0054] The linkage part 22 is arranged in the housing 3. Figures 4 to 9 As shown, the linkage portion 22 includes a connecting rod 221 and a torsion spring 222. One end of the connecting rod 221 is connected to the clamping member 12, forming a first transfer point 24 on the clamping member 12. The other end of the connecting rod 221 is connected to the driving member 21, forming a second transfer point 25 on the driving member 21. The driving member 21 is also provided with a first limiting post 26. The first end of the torsion spring 222 is sleeved and fixed on the first limiting post 26. The housing 3 is provided with a second limiting post 36. The second end of the torsion spring 222 is sleeved and fixed on the second limiting post 36. In the current embodiment, the first limiting post 26 and the second limiting post 36 are located between the first transfer point 24 and the second transfer point 25.

[0055] Specifically, the driving member 21 includes a driving handle 211 and a placement plate 215. The driving handle 211 is also provided with a recessed portion, the connecting rod 221 is connected to the recessed portion, and the placement plate 215 covers the top of the recessed portion and is fixed to the driving handle 211 to minimize the interference between the placement plate 215 and the connecting rod 221. When the driving handle 211 is driven, the placement plate 215 and the driving handle 211 move synchronously. Figure 9 As shown, in the current embodiment, a third limiting post 213 is provided on the driving handle 211. The third limiting post 213 is arranged on the axis of the driving handle 211. The end of the third limiting post 213 away from the driving member 21 is provided with the above-mentioned adapter hole 212. Two fourth limiting posts 214 are also provided on both sides of the third limiting post 213. The placement plate 215 is provided with limiting holes corresponding to the third limiting posts 213 and the fourth limiting posts 214. The placement plate 215 is thus connected to the third limiting posts 213 and the fourth limiting posts 214 through the limiting holes on the placement plate 215 to fix the placement plate 215. The placement plate 215 has a protrusion protruding toward the clamping member 12. The first limiting post 26 is provided on the protrusion to fix the torsion spring 222.

[0056] like Figure 5 As shown, based on the setting of the above-mentioned linkage part 22, when the driving member 21 is in the first position (the clamping member 12 is in the first state away from the retaining member 11, and the clamping assembly 1 is in the third position on the same straight line as the driving assembly 2), the driving member 21 is located at the driving transfer point 23 of the shell 3, the connecting rod 221 is located at the first transfer point 24 of the clamping member 12, and the connecting rod 221 is located at the second transfer point 25 of the driving member 21, which are not collinear. Taking the case where the shell 3 is placed horizontally as an example (the axial direction of the shell 3 is parallel to the horizontal direction), the driving handle 211 is placed horizontally at this time, and the first transfer point 24 is located below the line connecting the driving transfer point 23 and the second transfer point 25; and at this time the torsion spring 222 is in an uncompressed state, and the deformation amount reaches the minimum value. When the shell 3 is placed horizontally, let the horizontal straight line passing through the driving transfer point 23 be the normal line. At this time, the angle between the axis of the driving handle 211 and the normal line is a, and a is 0°; as shown Figure 6 As shown, force is applied to the driving member 21 to rotate downward relative to the housing 3, the second transfer point 25 gradually moves upward, and the torsion spring 222 is gradually compressed. When the driving member 21 is at the critical position, the deformation of the torsion spring 222 reaches the maximum value, and the torsion spring 222 is compressed to the limit. At this time, a increases compared to the first position. For example, a can be 30° at this time; in other embodiments, it can also be 45° or other angles. At this time, the driving member 21 is at the critical position; as shown in FIG. Figure 7As shown, when the force driving member 21 passes the critical position, the force is withdrawn, and the torsion spring 222 is gradually released, further driving the second transfer point 25 to move upward until the driving transfer point 23, the first transfer point 24 and the second transfer point 25 are collinear, and the torsion spring 222 returns to the uncompressed state again, and the deformation reaches the minimum value. At this time, the effective rotational torque of the connecting rod 221 is zero, and it enters the dead point position. At this time, a increases compared to the critical position. For example, a can be 60° at this time; in other embodiments, it can also be 75° or other angles; the driving member 21 reaches the second position (the clamping member 12 remains in the second state close to the retaining member 11, and the clamping assembly 1 is in the fourth position set at an angle with the driving assembly 2). There is no external force, and the clamping member 12 no longer moves; the reverse force will cause the driving member 21 to compress the torsion spring 222 first and then release the torsion spring 222 before returning to the first position. The details will not be repeated. It should be noted here that the effective rotational torque is a term in the prior art, which refers to the inertia torque that maintains the rotation direction of the rotor unchanged when the rotor rotates around its axis.

[0057] like Figure 10 As shown, in some embodiments, a first stopper 31 and a second stopper 32 are further provided on opposite radial sides of the housing 3, so that when the driving member 21 is in the first state or the second state, the driving member 21 abuts against the first stopper 31 and the second stopper 32, respectively, thereby limiting excessive rotation of the driving member 21. In the current embodiment, when the driving member 21 is in the first state or the second state, the protrusion of the mounting plate 215 abuts against the first stopper 31 and the second stopper 32, respectively, to limit the position.

[0058] like Figure 4 、 Figure 13 and Figure 14 As shown, since the liquid discharge head 5 is connected to the holder 11, the liquid discharge head 5 needs to be connected to the liquid supply tube when in use. To facilitate the connection of the liquid supply tube and reduce interference, the holder 11 is provided with a liquid outlet 111. The liquid outlet 111 is provided on the side of the holder 11 facing away from the clamping member 12. When the liquid discharge head 5 is connected to the holder 11, the liquid outlet 111 communicates with the inlet of the liquid discharge head 5. The connection method between the liquid discharge head 5 and the holder 11 is not limited. The liquid inlet 27 is provided on the driving handle 211.

[0059] Specifically, the fixing mechanism also includes a connecting tube 4, a first end of the connecting tube 4 is closed, and a second end of the connecting tube 4 is connected to the retaining member 11, and the connecting tube 4 is connected to the liquid outlet 111 on the retaining member 11. The connecting tube 4 can be connected and fixed in the shell 3 by means of, but not limited to, snap connection or screw connection. A plug-in shaft 41 is provided on the connecting tube 4, and a flow port 42 is provided on the plug-in shaft 41 to connect to the inner cavity of the connecting tube 4; the driving handle 211 is also provided with a plug-in interface 216 connected to the liquid inlet 27, and the plug-in interface 216 and the third limiting column 213 are located on opposite sides of the driving handle 211. The plug-in interface 216 is plugged into the plug-in interface 216, so that the driving member 21 is rotated by the plug-in shaft 41. In order to ensure sealing, a sealing ring can also be provided between the plug-in shaft 41 and the driving member 21, so that when supplying liquid, the liquid can enter the connecting tube 4 from the liquid inlet 27 through the flow port 42, and be transported by the connecting tube 4 to the liquid outlet 111 and then enter the liquid outlet head 5 to discharge the liquid.

[0060] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. 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.
