Description

Technical Field

[0001] This utility model relates to a dripping device, and more particularly to an automatic flipping dripping device. Background Technology

[0002] Many dynamic decorative items have appeared on the market, such as hourglasses, flowing sand paintings, oil spouts, and volcanic ash displays. These items use gravity or buoyancy to create a dynamic effect by causing sand or oil to flow, serving a decorative or aesthetic purpose. However, since the amount of sand or oil in an item is limited, once the sand or oil has drained, the item needs to be turned over to restart. Current methods of turning these items are all manual, requiring viewers to intermittently flip them. This repetitive operation is tiring and inconvenient. Furthermore, if manual operation ceases, the dynamic effect stops, resulting in a less than ideal decorative effect. Utility Model Content

[0003] The purpose of this invention is to provide an automatic flipping dripping device that requires no manual operation, is more convenient to use, and has a better decorative effect.

[0004] To achieve the above objectives, this utility model provides an automatic flipping dripping device, including a bracket, a dripping tray, a drive motor, a reduction mechanism, a control system, and a battery. The dripping tray is flipped and mounted on the bracket, and the drive motor is mounted on the bracket. The reduction mechanism is located between the drive motor and the dripping tray, with its input end connected to the output end of the drive motor and its output end connected to the rotation shaft of the dripping tray. The control system is located on the bracket and electrically connected to both the drive motor and the battery to control the forward and reverse rotation of the drive motor.

[0005] Compared to existing technologies, this new technology features a drip tray that is rotatably mounted on a support. A drive motor is positioned on one side of the support, and its output drives the drip tray to rotate via a reduction gear. This allows the drip tray to automatically rotate and restart after each dripping cycle, eliminating the need for manual operation and making it extremely convenient to use. Furthermore, the automatic rotation ensures a continuous dynamic dripping effect, resulting in a better decorative effect and enhanced aesthetic appeal.

[0006] Preferably, the control system includes a control unit and a timing unit. The timing unit is electrically connected to the control unit, and the control unit is electrically connected to the drive motor. The control unit controls the drive motor to rotate forward and backward after a set time has elapsed. Since the drip tray will drain completely within a certain time and needs to be flipped over to start dripping again, the timing unit controls the start of the drive motor. When the drip tray runs out of water, it is automatically flipped to start dripping again, thus automatically restarting the drip tray without manual operation. Furthermore, the drive motor does not operate during the dripping process, effectively reducing power consumption and saving energy.

[0007] Preferably, the support includes two forked arms, with the opposite sides of the drip tray pivotally connected to the two forked arms respectively, and the drive motor disposed on one of the forked arms. By using the two forked arms to support the opposite sides of the drip tray, the force on the drip tray is more even, resulting in smoother rotation.

[0008] Specifically, the bracket also includes a control box, in which the control system and the battery are housed. This allows the control system and the battery to be stored internally, providing a stable base for the dripping device and making the entire device more concise and aesthetically pleasing.

[0009] Preferably, at least one of the bracket and the drip tray is provided with a limiting block to abut against the other when the drip tray is rotated at a certain angle, thereby restricting the drip tray. This allows the drip tray to be positioned and prevents it from rotating excessively.

[0010] Specifically, the control system includes a current detection unit to detect the current of the drive motor when the limiting block restricts the rotation of the drip tray, and to disconnect the current to the drive motor when the current is too high. When the limiting block restricts the rotation of the drip tray, the circuit current of the drive motor will suddenly increase. Therefore, by setting up a current detection unit, the magnitude of the current can be detected when the drip tray is blocked by the limiting block, thereby controlling the drive motor to stop running through the control system, so that the drip tray stops rotating. This can not only accurately control the rotation angle of the drip tray, but also avoid the continuous operation of the drive motor, saving energy and extending the service life of the drive motor.

[0011] Preferably, the automatic flipping drip device further includes a lamp tube or light strip, the lamp tube being disposed on the outer periphery of the drip tray, and the light-emitting element inside the lamp tube being electrically connected to the control system. By adding a lamp tube or light strip to the outer periphery of the drip tray, the aesthetics of the drip tray are further enhanced.

[0012] Specifically, a clutch is provided between the deceleration mechanism and the drip tray to separate the output end of the deceleration mechanism from the rotation shaft of the drip tray when the limiting block restricts the rotation of the drip tray. The clutch prevents the drive motor from excessively rotating the drip tray, thus effectively protecting it.

[0013] Specifically, the drip tray has a hollow roller on the side near the drive motor. The clutch includes a damping rubber ring, which is fitted onto the output end of the drive motor and inside the roller, making frictional contact with the inner wall of the roller. By providing the roller, the damping rubber ring can be accommodated, making the connection between the output end of the drive motor and the drip tray more compact. Furthermore, the damping rubber ring can provide friction to the roller when the drive motor outputs torque, thereby causing the drip tray to rotate. It can also provide resistance when the drip tray is limited by the limiting block, increasing the current driving the drive motor and facilitating control to stop the drive motor. Additionally, when the drive motor generates excessive torque, the damping rubber ring can slip against the roller, protecting both the drive motor and the roller. Moreover, the damping rubber ring can prevent damage to the drive motor or reduction mechanism when the user forcibly rotates the drip tray.

[0014] Specifically, the clutch further includes a transmission wheel connected to the output end of the drive motor. The damping rubber ring is fitted onto a positioning groove on the outer circumference of the transmission wheel, and the transmission wheel is fitted inside the drum. The transmission wheel can limit the position of the damping rubber ring, preventing it from shifting relative to the drum and ensuring the stability of the drive motor driving the drum.

[0019] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] Please see Figure 1 and Figure 2 The automatic flipping drip device 100 of the present invention includes a bracket 1, a drip tray 2, a drive motor 3, a reduction mechanism 4, a control system 5, and a battery 6. The drip tray 2 is pivotally connected to the bracket 1 on opposite sides, making it flip-mounted on the bracket 1. The drive motor 3 is mounted on the bracket 1; two drive motors 3 can be used, respectively mounted on both sides of the drip tray 2, or one drive motor 3 can be used, mounted on one side of the drip tray 2. The reduction mechanism 4 is located between the drive motor 3 and the drip tray 2, with its input end connected to the output end of the drive motor 3, and its output end connected to the rotation shaft 21 of the drip tray 2. Specifically, the reduction mechanism 4 includes a first gear 41 and a second gear 42, the diameter of the first gear 41 being smaller than the diameter of the second gear 42. The central axis of the first gear 41 is connected to the output end of the drive motor 3, and the first gear 41 meshes with the second gear 42. The central axis of the second gear 42 is connected to the rotation shaft 21 of the drip tray 2. The control system 5 is disposed on the bracket 1 and electrically connected to the drive motor 3 and the battery 6 respectively, so as to control the drive motor 3 to rotate forward and backward.

[0021] For example Figure 2 As shown, the control system 5 includes a control unit 51 and a timing unit 52. The timing unit 52 is electrically connected to the control unit 51, and the control unit 51 is electrically connected to the drive motor 3. The control unit 51 controls the drive motor 3 to rotate forward and backward after a set time has elapsed. Since the dripping tray 2 will drain completely within a certain time and needs to be flipped over to start dripping again, the timing unit 52 is used to control the start of the drive motor 3. When the dripping tray 2 drains completely, it is driven to flip over and start dripping again, thus automatically restarting the dripping tray 2 without manual operation. Furthermore, the drive motor 3 does not operate during the dripping process, effectively reducing power consumption and saving energy. The time setting of the timing unit 52 can be determined according to the dripping time of different dripping trays 2, generally slightly longer than the time required for the dripping tray 2 to drain completely.

[0022] For example Figure 1As shown, the support 1 includes two forked arms 11, with the two opposite sides of the drip tray 2 pivotally connected to the two forked arms 11 respectively. The drive motor 3 is disposed on one of the forked arms 11. In this embodiment, the drip tray 2 is circular, and the two forked arms 11 together form a semi-circular structure, with the diameter of the circle being larger than the diameter of the drip tray 2. The drip tray 2 is disposed between the two forked arms 11, and the upper end of the forked arms 11 is pivotally connected to the rotation shaft 21 of the drip tray 2. By using the two forked arms 11 to support the two opposite sides of the drip tray 2, the force on the drip tray 2 is more even, thus making the rotation more stable. The support 1 also includes a control box 12, in which the control system 5 and the battery 6 are disposed. This allows the control system 5 and the battery 6 to be housed internally, providing a stable base for the dripping device and making the entire dripping device simpler and more aesthetically pleasing. More specifically, a support cylinder 13 or a bearing is fixedly provided at the upper end of the fork arm 11, and the rotating shafts 21 at both ends of the drip tray 2 are provided on the support cylinder 13 or the bearing.

[0023] For example Figure 1 As shown, at least one of the bracket 1 and the drip tray 2 is provided with a limiting block 14, which abuts against the other when the drip tray 2 is rotated at a certain angle, thereby restricting the drip tray 2. This can position the drip tray 2 and prevent it from rotating excessively. In this embodiment, the limiting block 14 is provided on the bracket 1, specifically, the limiting block 14 is respectively provided on the inner side of the two fork arms 11, and an abutment block 2a is provided at the corresponding position on the outer peripheral edge of the drip tray 2. When the drip tray 2 is rotated 180 degrees, the upper outer peripheral edge of the drip tray 2 rotates downward 180 degrees, and the abutment block 2a abuts against the limiting block 14 to limit its rotation.

[0024] Please see Figure 2 The control system 5 includes a current detection unit 53 to detect the current of the drive motor 3 when the limiting block 14 restricts the rotation of the drip tray 2, and disconnects the current of the drive motor 3 when the current is too high. When the limiting block 14 restricts the rotation of the drip tray 2, the circuit current of the drive motor 3 will suddenly increase. Therefore, by setting the current detection unit 53, the current magnitude can be detected when the drip tray 2 is blocked by the limiting block 14, thereby controlling the drive motor 3 to stop running through the control system 5, so that the drip tray 2 stops rotating. This can accurately control the rotation angle of the drip tray 2, avoid continuous operation of the drive motor 3, save energy, and extend the service life of the drive motor 3. The control system 5 also includes a control switch 54, which can manually control the start and stop of the drive motor 3, thereby facilitating the user to manually control the rotation of the drip tray 2.

[0025] For example Figure 1 As shown, the automatic flipping drip device 100 also includes a lamp tube 7 or a light strip. The lamp tube 7 is disposed on the outer periphery of the drip tray 2, and the light-emitting element inside the lamp tube 7 is electrically connected to the control system 5. By adding a lamp tube 7 or a light strip to the outer periphery of the drip tray 2, the aesthetics of the drip tray 2 are further enhanced. The wire of the lamp tube 7 extends into the control box 12 through a hollow channel inside the fork arm 11, thereby avoiding the wires from being exposed.

[0026] In summary, the working principle of the automatic flipping dripping device 100 of this utility model will be described in detail below:

[0027] When the drip tray 2 needs to be flipped, the drive motor 3 starts, and after being reduced in speed by the reduction mechanism 4, its output terminal drives the drip tray 2 to flip 180 degrees. When the drip tray 2 abuts against the limit block 14, it can no longer rotate, and the current in the circuit of the drive motor 3 increases. At this time, the current detection unit 53 detects the increased current and then controls the drive motor 3 to stop through the control system 5. The drip tray 2 is in the flipped state, and it can then drip again. At the same time that the drive motor 3 stops rotating, the timing unit 52 starts timing. When the timing unit 52 reaches the set time, the drip tray 2 has also finished dripping. At this time, the timing unit 52 can control the drive motor 3 to start again through the control system 5, thereby driving the drip tray 2 to flip 180 degrees again to drip again.

[0028] Compared with existing technologies, by tumbling the drip tray 2 onto the bracket 1 and placing a drive motor 3 on one side of the bracket 1, the output of the drive motor 3 drives the drip tray 2 to tumble through a reduction mechanism 4. This allows the drip tray 2 to automatically tumble and restart dripping after each dripping cycle, eliminating the need for manual operation and making it very convenient to use. Furthermore, because the automatic tumbling keeps the dynamic dripping effect continuous, the decorative effect is better and the aesthetic appeal is enhanced.

[0029] Please see Figure 3 and Figure 4 The figure shows a second embodiment of the automatic flipping dripping device 100' of this utility model.

[0030] like Figure 3 and Figure 4As shown, the automatic flipping drip device 100' in this embodiment has a similar structure to that in Embodiment 1, both having a timing unit, a current detection unit, and a manual switch. The difference lies in the shape of the fork arm 11', the combination of the drive motor and the reduction mechanism is changed to a reduction motor 3', and in this embodiment, a clutch 7 is provided between the reduction mechanism 4' and the drip tray 2'. The fork arm 11' has a vertical columnar structure, and the reduction motor 3' is located at the upper end of one of the fork arms 11'. Limiting blocks 14' are provided on opposite sides of the fork arm 11'. After the drip tray 2' flips 180 degrees, it is limited by one of the limiting blocks 14', and after flipping 180 degrees in the opposite direction, it is limited by the other limiting block 14'. The clutch 7 can separate the output end of the reduction mechanism 4' from the rotating shaft 21' of the drip tray 2' when the limiting block 14' restricts the flipping of the drip tray 2'. Therefore, the clutch 7 is provided to prevent the geared motor 3' from driving the drip tray 2' to overturn, thereby effectively protecting the drip tray 2'.

[0031] For example Figure 3 and Figure 4 As shown, specifically, a hollow roller 22' is fixedly provided on the side of the drip tray 2' near the geared motor 3'. The clutch 7 includes a damping rubber ring 71, which is sleeved on the output end of the geared motor 3' and inside the roller 22', with the damping rubber ring 71 in frictional contact with the inner wall of the roller 22'. By setting the roller 22', the damping rubber ring 71 can be accommodated, making the connection structure between the output end of the geared motor 3' and the drip tray 2' more compact. Furthermore, the damping rubber ring 71 can provide friction to the roller 22' when the reduction motor 3' outputs torque. At this time, the damping rubber ring 71 is fixed relative to the roller 22', thereby causing the drip tray 2' to rotate. The damping rubber ring 71 can also provide resistance when the drip tray 2' is limited by the limiting block 14', increasing the current driving the reduction motor 3', thus facilitating the control of stopping the reduction motor 3'. In addition, the damping rubber ring 71 can also slip against the roller 22' when the reduction motor 3' generates excessive torque, thereby protecting the reduction motor 3' and the roller 22'. Furthermore, the damping rubber ring 71 can also slip against the roller 22' when the user forcibly rotates the drip tray 2', thus preventing damage to the reduction motor 3'. In addition, the outer side of the roller 22' is provided with a stop block 2a', which can abut against either of the two limiting blocks 14', thereby limiting the drip tray 2'.

[0032] For example Figure 3 and Figure 4As shown, the clutch 7 also includes a transmission wheel 72, which is connected to the output end of the reduction motor 3'. The damping rubber ring 71 is fitted onto the positioning groove 721 on the outer periphery of the transmission wheel 72, and the transmission wheel 72 is fitted inside the roller 22'. The transmission wheel 72 can limit the position of the damping rubber ring 71, preventing the damping rubber ring 71 from shifting relative to the roller 22', thus ensuring the stability of the reduction motor 3' driving the roller 22'.

[0033] The working principle and technical effect of the automatic flipping drip device 100' in this embodiment are the same as those in embodiment one. For details, please refer to embodiment one, and it will not be described again here.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model shall still fall within the scope of the present utility model.
