Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom equipment technology, and in particular to a fixing mechanism and liquid dispensing device. Background Technology

[0002] Shower heads are widely used in liquid dispensing devices in kitchens and bathrooms. In related technologies in the bathroom industry, shower heads can include waist spray shower heads and handheld shower heads. Currently, waist spray shower heads and handheld shower heads often exist as two separate components, each fixed to a mounting bracket on a shower head holder. When using a waist spray shower head, the handheld shower head needs to be fixed to the shower rod. When changing it, the waist spray shower head needs to be fixed to the shower rod first, and then the handheld shower head needs to be detached from the shower rod. Furthermore, when adjusting the fixed position on the shower rod, the mounting bracket needs to be moved on the shower rod, and then the waist spray shower head and handheld shower head need to be fixed to the mounting bracket. This results in a complex overall structure of the shower head, and the time required for switching between uses and adjusting the fixed position is long, reducing the user experience.

[0014] In some embodiments, when the drive member is in the second position, the drive member at the drive transition point of the housing, the connecting rod at the first transition point of the clamping member, and the connecting rod at the second transition point of the drive member are collinear.

[0015] In some embodiments, when the drive member is located at the critical position, the deformation of the torsion spring reaches its maximum value; when the drive member is located at the first position or the second position, the deformation of the torsion spring reaches its minimum value.

[0016] In some embodiments, a first limiting block and a second limiting block are provided inside the housing, and when the driving member is in the first state or the second state, the driving member abuts against the first limiting block or the second limiting block.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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 based on the specific circumstances.

[0045] 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.

[0046] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] like Figures 1 to 14As shown, this application provides a liquid dispensing device, which includes a liquid dispensing head 5 and a fixing mechanism. 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, which is connected to the clamping member 12. The liquid dispensing 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 switch 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 component 6. At this time, the clamping assembly 1 is in a third position on the same straight line as the driving assembly 2. When the clamping member 12 is close to the retaining member 11, the two can clamp the external component 6. At this time, the clamping assembly 1 is in a fourth position with an angle set with the driving assembly 2.

[0048] The aforementioned liquid dispensing device can clamp the external component 6 (such as a shower rod) together with the retaining member 11 and the clamping member 12, so that the liquid dispensing head 5 can be fixed at any position on the external component 6. At this time, the clamping component 1 and the driving component 2 are in the fourth position with an included angle. At this time, the liquid dispensing device is fixed on the shower rod and used as a waist spray. When switching the use state, it is only necessary to drive the driving component 21 to change from the second position to the first position, so that the clamping component 1 changes to the third position that is in the same straight line as the driving component 2, so that it is convenient to hold and use as a handheld shower head. Thus, by adjusting the position of the driving component 21, the clamping and fixing of the waist spray and the handheld shower head can be switched, making the switching more convenient, minimizing the adjustment time, and improving the user experience.

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

[0050] It should be noted that the liquid outlet head 5 adopts a rod-shaped water outlet head, which makes it easy to use as a waist spray. The specific structure is not limited. The liquid outlet device can also be used for kitchen faucets and shower heads. The specific application is not limited.

[0051] In some embodiments, the drive member 21 also includes a critical position located between the first position and the second position. After the drive member 21 passes the critical position, the drive member 21 can automatically move to the first position or the second position. Thus, once the drive member 21 passes the critical position, no further force needs to be applied, making state adjustment more effortless and convenient.

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

[0053] Specifically, such as Figure 3 and Figure 11 As shown, the fixing mechanism includes a housing 3, which serves as the mounting base. The housing 3 has an inner cavity, and a mounting 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 mounting notch 33. The external component 6 is placed in the mounting notch 33, and the external component 6 is clamped or released as the clamping member 12 moves closer to or further away from the retaining member 11 along the axial direction of the housing 3. The housing 3 also has 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 driving member 21 is provided with a connecting post 35, and the other is provided with a connecting hole 212. The connecting post 35 is connected to the connecting hole 212, allowing the driving member 21 to rotate relative to the housing 3 through the connecting post 35 and the connecting hole 212, thus forming a driving connection point 23 on the housing 3. In the current embodiment, the connecting hole 212 is provided on the driving member 21, and the connecting post 35 is provided on the housing 3; specifically, the connecting post 35 can be separately provided from the housing 3, and the housing 3 is provided with a insertion hole, and the connecting post 35 can be a bolt post that is inserted into the insertion hole, thereby facilitating installation. In some alternative embodiments, the connecting post 35 can also be integrally formed with the housing 3.

[0054] The linkage part 22 is located inside the housing 3, such as Figures 4 to 9 As shown, the linkage 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 transition 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 transition 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, and 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 transition point 24 and the second transition point 25.

[0055] Specifically, the driving component 21 includes a driving handle 211 and a mounting plate 215. The driving handle 211 also has a recessed portion, and the connecting rod 221 is connected to the recessed portion. The mounting plate 215 covers the recessed portion and is fixed to the driving handle 211 to minimize interference between the mounting plate 215 and the connecting rod 221. When the driving handle 211 is driven, the mounting 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 drive handle 211, and the third limiting post 213 is located on the axis of the drive handle 211. The end of the third limiting post 213 away from the drive member 21 is provided with the aforementioned adapter hole 212. Two fourth limiting posts 214 are also provided on both sides of the third limiting post 213. The mounting plate 215 is provided with limiting holes corresponding to the third limiting post 213 and the fourth limiting post 214, so that the mounting plate 215 is sleeved on the third limiting post 213 and the fourth limiting post 214 through the limiting holes on the mounting plate 215 to fix the mounting plate 215. The mounting plate 215 has a protrusion protruding towards the clamping member 12, and a first limiting post 26 is provided on the protrusion to fix the torsion spring 222.

[0056] like Figure 5 As shown, based on the above-mentioned linkage 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 at the driving transition point 23 of the housing 3, the connecting rod 221 at the first transition point 24 of the clamping member 12, and the connecting rod 221 at the second transition point 25 of the driving member 21 are not collinear. Taking the housing 3 as an example when it is horizontally placed (the axis of the housing 3 is parallel to the horizontal direction), the driving handle 211 is horizontally placed, and the first transition point 24 is located below the line connecting the driving transition point 23 and the second transition point 25; and at this time, the torsion spring 222 is in an uncompressed state, and the deformation reaches its minimum value. When the housing 3 is horizontally placed, let the straight line in the horizontal direction passing through the driving transition point 23 be the normal line, and the angle between the axis of the driving handle 211 and the normal line is α, where α is 0°; Figure 6 As shown, a force is applied to the driving member 21 to rotate downward relative to the housing 3, the second transition 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 its maximum value, and the torsion spring 222 is compressed to its limit. At this time, 'a' increases compared to the first position. For example, 'a' can be 30°; in other embodiments, it can also be 45° or other angles. At this time, the driving member 21 is at the critical position. Figure 7As shown, when the force-applying drive member 21 crosses the critical position, the force is withdrawn, and the torsion spring 222 is gradually released, further driving the second transition point 25 to move upward until the three points of drive transition point 23, first transition point 24 and second transition point 25 are collinear. The torsion spring 222 returns to the uncompressed state, 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 position. At this time, 'a' is larger than that at the critical position. For example, 'a' can be 60° at this time; in other embodiments, it can also be 75° or other angles. When the drive member 21 reaches the second position (the clamping member 12 is in the second state close to the retaining member 11, and the clamping assembly 1 is in the fourth position with the angle set with the drive assembly 2), without external force, the clamping member 12 no longer moves; applying force in the opposite direction will cause the drive member 21 to first compress the torsion spring 222 and then release the torsion spring 222 before returning to the first position. The specific details will not be elaborated further. It should be noted that the effective rotational torque is a technical term that refers to the inertial torque that maintains the direction of rotation of a rotor when it rotates around its axis.

[0057] like Figure 10 As shown, in some embodiments, a first limiting block 31 and a second limiting block 32 are also provided on opposite radial sides inside 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 limiting block 31 and the second limiting block 32 respectively, thereby limiting the 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 protruding part of the mounting plate 215 abuts against the first limiting block 31 and the second limiting block 32 respectively for limiting.

[0058] like Figure 4 , Figure 13 and Figure 14 As shown, since the liquid outlet 5 is connected to the retainer 11, the liquid outlet 5 needs to be connected to the liquid supply pipe during use. To facilitate the connection of the liquid supply pipe and reduce interference, the retainer 11 is provided with a liquid outlet 111. The liquid outlet 111 is located on the side of the retainer 11 away from the clamping member 12. When the liquid outlet 5 is connected to the retainer 11, the liquid outlet 111 communicates with the inlet of the liquid outlet 5. The connection method between the liquid outlet 5 and the retainer 11 is not limited. The liquid inlet 27 is provided on the drive handle 211.

[0059] Specifically, the fixing mechanism also includes a connecting pipe 4. The first end of the connecting pipe 4 is closed, and the second end of the connecting pipe 4 is connected to the retaining member 11, so that the connecting pipe 4 is connected to the liquid outlet 111 on the retaining member 11. The connecting pipe 4 can be connected and fixed in the housing 3 by means of snap-fit ​​or screw connection, etc. The connecting pipe 4 is provided with a plug shaft 41, and the plug shaft 41 is provided with a flow port 42 that connects to the inner cavity of the connecting pipe 4. The drive handle 211 is also provided with a plug interface 216 that communicates with the liquid inlet 27. The plug interface 216 and the third limiting post 213 are located on opposite sides of the drive handle 211. The plug shaft 41 is plugged into the plug interface 216, so that the drive member 21 can rotate through the plug shaft 41. In order to ensure sealing, a sealing ring can also be provided between the plug shaft 41 and the drive member 21. Then, when supplying liquid, the liquid can enter the connecting pipe 4 from the liquid inlet 27 through the flow port 42, and be transported by the connecting pipe 4 to the liquid outlet 111 and then enter the liquid outlet head 5 for liquid discharge.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
