Technical Field

[0001] This utility model relates to a swing water outlet device with a damping structure. Background Technology

[0002] In the current coffee brewing process, coffee lovers generally prefer pour-over coffee, which involves holding a kettle by hand and pouring hot water evenly into the brewing chamber where the coffee grounds are placed. There are various ways to pour hot water, such as circular, spiral, sprinkler, or concentrated jet pouring, and the speed and time of pouring are combined to brew a delicious cup of coffee. In order to meet the needs of coffee lovers, current coffee machines have developed mechanisms that can simulate the human hand to rotate and brew coffee. However, the current rotating mechanisms are relatively complex and have high production costs. Summary of the Invention

[0003] This utility model discloses a swing water outlet device with a damping structure, which aims to solve the above-mentioned problems.

[0004] The present invention adopts the following solution:

[0005] A damping-structured oscillating water outlet device includes a base and an outlet pipe assembly; it further includes: a wear-resistant ring, rotatably mounted on the base, with an outlet support rotatably mounted within the wear-resistant ring; the outlet pipe assembly is configured to be inserted into the outlet support to achieve oscillating water flow; an elastic element, one end of which is configured to abut against the wear-resistant ring to tightly fit the wear-resistant ring against the base; and a fixed seat, connected to the base via a locking screw, which abuts against the other end of the elastic element; the locking screw can change the positional relationship between the fixed seat and the base to change the tightness of the pressure on the elastic element.

[0006] In this embodiment of the utility model, the base is provided with a plug hole, a stop block is provided in the plug hole, and the wear-resistant ring is configured to be located in the plug hole; the outer periphery of the wear-resistant ring is provided with a flange, the upper end face of the flange can abut against the lower end face of the stop block, and the lower end face of the flange is configured to abut against the upper end face of the elastic element.

[0007] In this embodiment of the present invention, the fixed base is provided with a protruding ring, which is configured to abut against the lower end surface of the elastic element so as to tightly fit the flange with the stop block.

[0008] In this embodiment of the utility model, a boss is provided on the side wall of the base located on the outer periphery of the insertion hole, and an arc-shaped piece is provided on the outer periphery of the fixing seat located on the outer periphery of the convex ring. When the fixing seat is connected to the base, the arc-shaped piece is configured to be located on the outer periphery of the boss so that the fixing seat and the base do not rotate relative to each other. The locking screw is configured to be located on the inner periphery of the arc-shaped piece.

[0009] In this embodiment of the utility model, the elastic element is one or a combination of two or more of the following: a disc spring, a helical spring, or a wave-shaped washer. The elastic element is configured to be sleeved on the outer periphery of a wear-resistant ring located below the flange.

[0010] In this embodiment of the invention, a driving mechanism is provided on the base located on the outer periphery of the wear-resistant ring. The driving mechanism is configured to drive the wear-resistant ring and the water outlet device to rotate relative to the base.

[0011] In this embodiment of the utility model, the water outlet bracket includes a connecting pipe, and the water outlet pipe assembly is configured to be inserted into the connecting pipe; a pin is provided on the outer peripheral wall of the connecting pipe, and a shaft hole is provided on the wear-resistant ring; the pin can cooperate with the shaft hole to enable the connecting pipe to rotate relative to the wear-resistant ring, thereby changing the positional relationship between the connecting pipe and the axis of the wear-resistant ring.

[0012] In this embodiment of the invention, a notch is provided on the side wall of the wear-resistant ring, and a connecting rod is provided on the connecting pipe. The connecting rod is configured to move between the side walls at both ends of the notch, so as to realize the rotation of the connecting pipe relative to the wear-resistant ring.

[0013] In this embodiment of the utility model, the driving mechanism includes a gear disposed on the base, the gear being rotatable relative to the base and disposed on the outer periphery of the wear-resistant ring, the gear having a socket disposed on the inner periphery, and the connecting rod being configured to be inserted into the socket. The rotation of the gear relative to the base can first cause the connecting pipe to rotate relative to the wear-resistant ring, and then drive the connecting pipe and the wear-resistant ring to rotate relative to the base.

[0014] In this embodiment of the utility model, the driving mechanism further includes a drive motor that can be fixed on the base. The drive motor can drive a drive wheel disposed on the base to rotate. The drive wheel is configured to mesh with a gear.

[0015] The working principle of this utility model is as follows: S1. The elastic element provides constant pressure, pressing the wear-resistant ring tightly onto the base. When the wear-resistant ring rotates relative to the base, sliding friction is generated between them, forming a damping torque. S2. The water outlet bracket cooperates with the wear-resistant ring through a connecting pipe. The connecting pipe can rotate relative to the wear-resistant ring, realizing the oscillating water outlet effect of the water outlet assembly. S3. The drive mechanism, through the action of gears and a drive motor, first causes the connecting pipe to rotate relative to the wear-resistant ring, and then drives the connecting pipe and the wear-resistant ring to rotate relative to the base, thereby realizing a complex oscillating water outlet pattern. S4. By adjusting the locking screw, the compression degree of the elastic element is changed, thereby fine-tuning the magnitude of the damping force to meet the needs of different application scenarios.

[0016] This invention provides a damping-structured oscillating water outlet device with the following advantages: A stable damping torque is achieved through the cooperation of the base, wear-resistant ring, elastic element, and fixed seat; the overall structure is compact and easy to manufacture. The compression degree of the elastic element can be changed by adjusting the locking screw, thereby flexibly adjusting the damping force. After the elastic element is fixed in position between the fixed seat and the base, it provides constant pressure, ensuring uniform distribution of friction between the wear-resistant ring and the base, resulting in a stable and reliable damping torque. The wear-resistant ring, made of wear-resistant material, has a long service life and minimal damping force attenuation. This invention is suitable for high-end products requiring greater or more precise damping force, such as coffee machines and shower heads.

[0017] The present invention further optimizes the above-mentioned technical effects through the following technical details: 1. The design of the flange and stop block of the wear-resistant ring effectively prevents the wear-resistant ring from dislodging from the insertion hole due to excessive external force, while ensuring the relative positional stability between the wear-resistant ring and the base. 2. The material selection and structural design of the elastic element, combined with its installation method, allows for a wider and more precise adjustment range of the damping torque, meeting the needs of different scenarios. 3. The drive mechanism uses the cooperation of gears and connecting rods to achieve linkage between the connecting pipe and the wear-resistant ring through the rotation of the gears, simplifying the transmission structure and improving the operational stability of the device. 4. The design of the arc-shaped plate and boss between the fixed seat and the base prevents relative rotation between the fixed seat and the base through geometric limiting, ensuring the overall stability of the device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0027] Referring to the accompanying drawings, the device includes a base 1, a insertion hole 2, a stop block 3, a wear-resistant ring 4, a flange 5, an elastic element 6, a fixing seat 7, a protruding ring 8, a locking screw 9, an arc-shaped piece 10, a boss 11, a water outlet bracket 12, a connecting pipe 13, a pin 14, a shaft hole 15, a connecting rod 16, a notch 17, a gear 18, a socket 19, a drive motor 20, a drive wheel 21, and a water outlet pipe assembly 22. The base can be a complete housing, and the water outlet pipe assembly includes a flexible water outlet hose that can be inserted into the water outlet bracket. The direction of water flow from the hose is changed by rotating the water outlet bracket.

[0028] The base 1 serves as the foundation of the entire device, and it is equipped with a insertion hole 2 for mounting the wear-resistant ring 4. A stop 3 protrudes inward from the inner peripheral wall of the insertion hole 2. The stop 3 restricts the vertical displacement of the wear-resistant ring 4; it can also be a ring-shaped component to prevent the wear-resistant ring 4 from detaching from the insertion hole 2 due to external force. The wear-resistant ring is inserted into the insertion hole from bottom to top. The wear-resistant ring 4 is positioned by engaging with the stop 3 through its outer flange 5, with the upper end face of the flange 5 contacting the lower end face of the stop 3 to form a limiting relationship. Simultaneously, the lower end face of the flange 5 contacts the upper end face of the elastic element 6, and the lower end face of the elastic element 6 abuts against the protruding ring 8 on the fixed base 7. This multi-layer contact design ensures uniform and stable pressure distribution between the wear-resistant ring 4 and the base 1. The elastic element 6 is selected from one or more combinations of disc springs, coil springs, or wave washers, and is fitted around the outer periphery of the wear-resistant ring 4 to provide constant pressure. The degree of compression of the elastic element 6 can be changed by adjusting the positional relationship between the fixed seat 7 and the base 1, thereby adjusting the magnitude of the damping torque.

[0029] The fixed seat 7 is connected to the base 1 via a locking screw 9. A raised ring 8 is designed at the upper end of the fixed seat 7, which directly presses against the lower end face of the elastic element 6, causing the elastic element 6 to apply upward pressure to the wear-resistant ring 4. Furthermore, a boss 11 is provided on the outer periphery of the base 1, and an arc-shaped piece 10 is correspondingly designed on the outer side of the fixed seat 7. The position of the arc-shaped piece 10 matches the boss 11. When the fixed seat 7 is connected to the base 1, the arc-shaped piece 10 surrounds the outer periphery of the boss 11, preventing the fixed seat 7 from rotating relative to the base 1. The locking screw 9 passes through the inner periphery of the arc-shaped piece 10 and is threadedly connected to the base 1. A threaded hole that mates with the locking screw can be provided on the boss. By tightening or loosening the locking screw 9, the distance between the fixed seat 7 and the base 1 can be changed, thereby adjusting the compression of the elastic element 6. This structural design not only ensures the stability between the fixed seat 7 and the base 1 but also achieves precise adjustment of the damping torque.

[0030] The wear-resistant ring 4 has an internal water outlet bracket 12, the core component of which is a connecting pipe 13. A pin 14 is mounted on the outer peripheral wall of the connecting pipe 13, and a corresponding shaft hole 15 is provided on the inner wall of the wear-resistant ring 4. The axial direction of the shaft hole can coincide with the radial direction of the wear-resistant ring and the connecting pipe. Inserting the pin 14 into the shaft hole 15 allows the connecting pipe 13 to rotate relative to the wear-resistant ring 4. This design allows the connecting pipe 13 to adjust its axial position relative to the wear-resistant ring 4 within a certain range, thus laying the foundation for the subsequent oscillating water outlet effect of the water outlet assembly 22. Furthermore, a notch 17 is provided on the side wall of the wear-resistant ring 4, and a connecting rod 16 is fixed to the outer periphery of the connecting pipe 13. The connecting rod 16 can move between the side walls at both ends of the notch 17, allowing further rotation of the connecting pipe 13 relative to the wear-resistant ring 4. This mechanical linkage not only simplifies the transmission structure but also improves the overall reliability of the device. Specifically, when the water outlet support is in state one, the connecting pipe and the wear-resistant ring are coaxial, and the connecting rod is in contact with the side wall of the notch. At this time, the gear rotates, which drives the connecting pipe to rotate relative to the wear-resistant ring through the connecting rod, causing the axes of the connecting pipe and the wear-resistant ring to tilt. At the same time, the connecting rod contacts the other side wall of the notch. This is state two, where the gear continues to drive the water outlet support and the wear-resistant ring to rotate together relative to the base (when this rotation occurs, the water outlet support and the wear-resistant ring are in an inclined state).

[0031] To achieve more complex oscillating water discharge patterns, this invention also includes a drive mechanism on the base 1. The core components of the drive mechanism are a gear 18 and a drive motor 20. The gear 18 is mounted on the base 1 and can rotate relative to it. The gear has an insertion port 19 on its inner circumference; the connecting rod 16, after being inserted into the port 19, moves with the rotation of the gear 18. The drive motor 20 is fixed to the base 1 and meshes with the gear 18 through a drive wheel 21. When the drive motor 20 starts, it drives the drive wheel 21 to rotate, which in turn drives the gear 18 to rotate. The rotation of the gear 18 first drives the connecting rod 16 to rotate the connecting pipe 13 relative to the wear-resistant ring 4, and then drives both the connecting pipe 13 and the wear-resistant ring 4 to rotate together relative to the base 1. This step-by-step drive design enables complex water discharge patterns from partial oscillation to overall rotation, meeting the needs of different application scenarios.

[0032] The working process of this utility model is as follows: S1. Start the drive motor 20, which drives the gear 18 to rotate via the drive wheel 21. S2. The rotation of the gear 18 first drives the connecting rod 16 to rotate the connecting pipe 13 relative to the wear ring 4. Since there is a degree of freedom of relative rotation between the connecting pipe 13 and the wear ring 4, the rotation of the connecting pipe 13 will change the positional relationship of its axis relative to the wear ring 4, thereby realizing the initial swinging action of the water outlet pipe assembly 22. S3. As the gear 18 continues to rotate, the connecting rod 16 will drive the connecting pipe 13 and the wear ring 4 to rotate together relative to the base 1, further expanding the swinging range of the water outlet pipe assembly 22. S4. During this process, the elastic element 6 always applies a constant pressure to the wear ring 4, so that the wear ring 4 and the base 1 generate sliding friction, forming a stable damping torque. By adjusting the locking screw 9 to change the compression degree of the elastic element 6, the magnitude of the damping torque can be flexibly adjusted to adapt to different usage requirements. At the same time, the drive motor can reverse after stopping, so that the water outlet bracket returns to the coaxial state with the wear-resistant ring. That is, in state two, the drive motor reverses, so that the connecting ring rotates from the other side wall of the notch back to its side wall. During this period, the wear-resistant ring does not rotate, so that the water outlet bracket can return to the correct position after each water discharge.

[0033] This invention is particularly suitable for high-end coffee machines that require simulation of pour-over coffee. In practical applications, users can adjust the damping torque by adjusting the locking screw 9, based on the particle size of the coffee grounds, the shape of the brewing chamber, and their personal taste preferences, thereby adjusting the oscillation frequency and amplitude of the water outlet component. For example, for scenarios requiring even coverage of coffee grounds, the damping torque can be appropriately increased, causing the water outlet component to complete a large-scale oscillation at a slower speed; while for scenarios requiring concentrated brewing, the damping torque can be decreased, causing the water outlet component to complete a small-scale oscillation at a lower speed. Furthermore, this invention can also be applied to showerheads, spray systems, and other applications requiring complex water flow patterns, demonstrating broad application prospects.

[0034] This invention achieves a compact, adjustable-damping, and stable oscillating water discharge function through the coordinated operation of the base 1, wear-resistant ring 4, elastic element 6, fixed seat 7, and drive mechanism. Specifically, the sliding friction between the wear-resistant ring 4 and the base 1 provides a stable damping torque, and the compression degree of the elastic element 6 can be precisely adjusted by the locking screw 9 to meet the needs of different scenarios. The drive mechanism, through the cooperation of gear 18 and connecting rod 16, realizes a complex motion mode from partial oscillation to overall rotation, which simplifies the transmission structure and improves the operational stability of the device. In addition, the arc-shaped plate 10 and boss 11 between the fixed seat 7 and the base 1 effectively prevent relative rotation between the two, ensuring the overall stability of the device.
