Description

Technical Field

[0001] This application relates to the technical field of water dispensers, and in particular to an automatic water dispenser barrel transport mechanism for an intelligent water dispenser. Background Technology

[0002] Water dispensers can be divided into direct drinking water dispensers and bottled water dispensers based on the water source. Bottled water dispensers, in particular, are widely used in homes, offices and various other places due to their simple structure, low cost, low installation requirements, and high adaptability.

[0003] Based on the installation location of the bottled water, bottled water dispensers can be divided into top-mounted dispensers (installed at the top of the machine) and bottom-mounted dispensers (installed at the bottom). Bottom-mounted dispensers are more convenient for changing water bottles than top-mounted dispensers because they don't require lifting the bottle. Furthermore, since the bottles are placed upright in bottom-mounted dispensers, the possibility of leakage is greatly reduced.

[0004] Traditional bottom-loading water dispensers typically require placing the bottled water in front of the compartment at the bottom of the dispenser, inserting the water hose, pushing the bottle into the compartment, and finally closing the door. This process is quite laborious. To address this, a new type of bottom-loading water dispenser with a sliding tray has emerged. This tray uses a sliding rail structure between itself and the bottom plate of the compartment, allowing the tray to slide the bottled water in and out of the compartment, simplifying operation and saving effort.

[0005] However, this type of sliding tray reveals a problem in actual use: when the tray is pulled out, the part extending out of the placement cavity is suspended in the air. After replacing a full load of bottled water, the enormous weight can easily cause the tray to bend and deform, which in turn affects the smooth cooperation between the slide rail and the slider. With long-term use, this will reduce the stability of sliding and may even cause the tray to jam and become unable to slide. Summary of the Invention

[0006] To reduce the problem of bottled water bending and deforming on the tray due to suspended stress, ensure the stability of bottled water during placement and removal, and further improve the service life of the tray, this application provides an automatic bottle transport mechanism for an intelligent water dispenser.

[0007] This application provides an automatic water dispenser barrel transport mechanism, which adopts the following technical solution: An automatic water dispenser bucket conveying mechanism, including a base; The power mechanism is mounted on the top surface of one end of the base; The tray is disposed on top of the power mechanism, and the output end of the power mechanism is fitted to the bottom of the tray, the power mechanism driving the tray to perform horizontal linear movement; A guide assembly includes a slider and a slide rail, the slider being fixed to the bottom surface of the tray and the slide rail being fixed to the top surface of the base, the slider and the slide rail being slidably connected; The guide wheel mechanism includes a mounting bracket, a mounting shaft, a connecting elastic element, a connecting frame, and guide wheels. The mounting bracket is fixed to the bottom surface of the tray and is located at the end away from the power mechanism. The connecting frame is rotatably connected to the mounting bracket via the mounting shaft. The connecting elastic element is sleeved on the mounting shaft, with one end assembled to the mounting bracket and the other end assembled to the connecting frame. The guide wheels are rotatably mounted on the connecting frame via a shaft connection.

[0008] By adopting the above technical solution, as the pallet extends out of the placement cavity, the guide wheels gradually contact the edge of the placement cavity or other supporting surfaces as the suspended portion of the pallet increases. At this time, the connecting elastic element will elastically expand and contract according to the force on the pallet, allowing the connecting frame to rotate around the mounting axis at a certain angle, thereby adjusting the position and force state of the guide wheels. The guide wheels can provide additional support for the pallet, reduce the bending deformation caused by the suspended force, and ensure the stability of the pallet during movement. As the pallet carries bottled water and returns to the base, the guide wheels can rotate flexibly, reducing the friction between the guide wheels and the supporting surfaces, further improving the smoothness of the pallet movement.

[0009] Compared with the prior art, this application effectively improves the structural stability of the pallet when bearing heavy objects through the synergistic effect of the guide wheel mechanism and the power mechanism.

[0010] Preferably, the connecting frame includes two assembly parts and one connecting part. One end of the assembly part is connected to the mounting bracket via the mounting shaft, and the other end of the assembly part is connected to a guide wheel. The two assembly parts are arranged in parallel and are respectively placed at both ends of the bottom side of the tray. The connecting part is arranged laterally and its two ends are respectively fixed to the two assembly parts.

[0011] Preferably, the outer wall of the guide wheel is covered with a buffer anti-slip layer.

[0012] By adopting the above technical solution, the two parallel assembly parts can support the two guide wheels respectively, providing balanced support force to both sides of the pallet and preventing the pallet from tilting or twisting due to uneven force. The connection part further enhances the overall structural strength of the connecting frame, enabling it to better bear and distribute the weight of the pallet and bottled water, thereby ensuring the stability and reliability of the pallet during movement.

[0013] The buffer anti-slip layer can effectively increase the friction between the guide wheel and the supporting surface, preventing the guide wheel from slipping during sliding. At the same time, it can also act as a buffer, reducing the hard impact between the guide wheel and the supporting surface, and helping to extend the service life of the guide wheel.

[0014] Preferably, the slide rail includes a circular track, the slider has a T-shaped structure, and the bottom end of the slider has an arc surface that is adapted to the surface of the circular track.

[0015] Preferably, the slider has inclined surfaces on both sides of its small end, the inclined surfaces are inclined downward from the large end of the slider to the arc surface, the slide rail includes a slide rail support seat, the top surface of the slide rail support seat has a flared opening that narrows from top to bottom, the circular track is disposed in the slide rail support seat, the part of the circular track protruding from the slide rail support seat slides in contact with the arc surface, and the inclined surfaces fit against the side of the flared opening.

[0016] By adopting the above technical solution, the combination design of the T-shaped slider and the circular track enables the slider to maintain good stability during sliding and is less prone to derailment. The arc surface design further reduces the contact area between the slider and the circular track, reduces frictional resistance, and improves the smoothness of sliding.

[0017] At the same time, the inclined surfaces on both sides of the small end of the slider fit into the flared opening on the top surface of the slide rail support, which can guide the slider smoothly into the slide rail and play a certain guiding and limiting role during the sliding process, reducing the slider from deviating in the horizontal direction.

[0018] Preferably, the power mechanism includes a lead screw, a mating block, and a power component. The mating block is fixed to the bottom surface of the tray. The extension direction of the lead screw and the extension direction of the slide rail are both consistent with the movement direction of the tray. The lead screw is assembled with the mating block, and the output end of the power component is assembled with the end of the lead screw.

[0019] Preferably, the power component includes a motor, a worm gear, and a worm. The power assembly consisting of the lead screw and the mating block has two sets. The end of the lead screw away from the guide wheel mechanism is provided with a connecting shaft, and the worm gear is mounted on the connecting shaft. The extension direction of the worm is perpendicular to the extension direction of the lead screw, and both ends of the worm mesh with the two worm gears respectively. The motor is connected to the worm through a coupling.

[0020] By adopting the above technical solution, the power mechanism converts the rotational motion of the motor into the linear motion of the pallet through the assembly of the lead screw and the mating block, ensuring the accuracy and stability of the pallet's movement. Simultaneously, the power component, composed of a motor, worm gear, and worm, utilizes the self-locking property of the worm gear transmission to effectively prevent the pallet from moving unexpectedly due to external forces when carrying heavy loads, thereby improving safety. Furthermore, this application employs a power assembly with two sets of lead screws and mating blocks, resulting in more even force distribution on the pallet and further enhancing its stability during movement.

[0021] Preferably, the top surface of the tray is provided with an anti-slip mat.

[0022] By adopting the above technical solution, the anti-slip mat can increase the friction between the tray and the placement surface and play a buffering role, which helps to reduce the water dispenser from sliding or shifting due to external forces during use and improves the placement stability of the water dispenser.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. As the pallet extends out of the placement cavity, the guide wheels gradually come into contact with the edge of the placement cavity or other supporting surfaces as the portion of the pallet is suspended. The connecting elastic element will elastically expand and contract according to the force on the pallet, allowing the connecting frame to rotate around the mounting axis at a certain angle. This adjusts the position and stress state of the guide wheels. The guide wheels can provide additional support for the pallet, reducing the bending deformation caused by the suspended force and ensuring the stability of the pallet during movement. As the pallet carries bottled water and returns to the base, the guide wheels can rotate flexibly, reducing friction with the supporting surface and further improving the smoothness of the pallet's movement. 2. The T-shaped slider and the circular track design enable the slider to maintain good stability during sliding and prevent it from derailing. The arc surface design further reduces the contact area between the slider and the circular track, reduces frictional resistance, and improves the smoothness of sliding.

[0024] At the same time, the inclined surfaces on both sides of the small end of the slider fit into the flared opening on the top surface of the slide rail support, which can guide the slider smoothly into the slide rail and play a certain guiding and limiting role during the sliding process, reducing the slider from deviating in the horizontal direction.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses an automatic water dispenser barrel transport mechanism.

[0032] Reference Figure 1 and Figure 2 An automatic water dispenser barrel conveying mechanism includes a base 1, a power mechanism 2, a tray 3, a guide assembly 4, and a guide wheel mechanism 5. The power mechanism 2 is installed on the top surface of one end of the base 1, and the tray 3 is placed on top of the power mechanism 2. The output end of the power mechanism 2 is assembled with the bottom of the tray 3, which can drive the tray 3 to perform horizontal linear movement. The guide assembly 4 includes a slider 41 and a slide rail 42. The slider 41 is fixed to the bottom surface of the tray 3, and the slide rail 42 is fixed to the top surface of the base 1. The slider 41 and the slide rail 42 are slidably connected, which guides the sliding of the tray 3. The guide wheel mechanism 5 includes a guide wheel 54, which is installed on the bottom surface of the tray 3 and arranged at the end away from the power mechanism 2. Through the cooperation of various components, the guide wheel 54 can provide support when the tray 3 is extended, which helps to improve the stability of the sliding of the tray 3.

[0033] Specifically, the power mechanism 2 includes a lead screw 21, a mating block 22, and a power component. There are two sets of power components consisting of the lead screw 21 and the mating block 22. The mating block 22 is fixed to the bottom surface of the tray 3. The extension direction of the lead screw 21 and the extension direction of the slide rail are both consistent with the movement direction of the tray 3. The lead screw 21 is assembled with the mating block 22. The lead screw 21 is a slender rod with threads on its surface. The mating block 22 is a rectangular block with a threaded hole inside that matches the thread of the lead screw 21. Motion transmission is achieved through the threaded engagement with the lead screw 21.

[0034] The power components include a motor 231, a worm gear (not shown in the figure), and a worm 232. A connecting shaft is provided at the end of the lead screw 21 away from the guide wheel mechanism 5. The worm gear is mounted on the connecting shaft. The extension direction of the worm 232 is perpendicular to the extension direction of the lead screw 21, and both ends of the worm 232 mesh with two worm gears respectively. The motor 231 is connected to the worm 232 through a coupling.

[0035] Furthermore, the motor 231 of this application is a DC motor 231, which helps to achieve convenient and precise speed adjustment of the pallet. In specific applications, the motor 231 drives the worm 232 to rotate, and the worm 232 drives the lead screw 21 to rotate through meshing with the worm wheel. The threaded engagement between the lead screw 21 and the mating block 22 converts the rotational motion into the linear motion of the pallet 3, thereby realizing the horizontal sliding of the pallet 3.

[0036] Reference Figure 1 and Figure 3 The guide assembly 4 includes a slider 41 and a slide rail 42. The slide rail 42 includes a circular track 421 and a slide rail 42 support. The top surface of the slide rail 42 support has a flared opening that narrows from top to bottom. The circular track 421 is disposed inside the slide rail 42 support. The slider 41 has a T-shaped structure. The bottom end of the slider 41 has an arc surface 412. The small end of the slider 41 has inclined surfaces 411 on both sides. The inclined surfaces 411 are inclined downward from the large end of the slider 41 to the arc surface 412. When the two are in contact, the part of the circular track 421 exposed in the slide rail 42 support slides into contact with the arc surface 412, and the inclined surfaces 411 fit against the side of the flared opening.

[0037] The guide component 4 provides precise guidance and stable support during the sliding of the tray 3. The T-shaped slider 41, with its bottom arc surface 412 fitting snugly against the inner circular track 421 of the slide rail 42, significantly reduces frictional resistance during sliding, thereby improving the smoothness of the tray 3's movement. Simultaneously, the inclined surfaces 411 on both sides of the small end of the slider 41 closely fit the flared opening on the top surface of the slide rail 42 support, not only guiding the slider 41 smoothly into the slide rail 42 but also limiting its horizontal movement during sliding to prevent deviation. This ensures the stability and reliability of the tray 3 during movement, allowing it to maintain stable linear motion when the water dispenser base 1 is carrying heavy loads.

[0038] Reference Figure 3 and Figure 4 The guide wheel mechanism 5 includes a mounting bracket 51, a mounting shaft 52, a connecting elastic element, a connecting frame 53, and a guide wheel 54. Specifically, the mounting bracket 51 is fixed to the bottom surface of the tray 3 and is arranged at the end away from the power mechanism 2. The connecting frame 53 is rotatably connected to the mounting bracket 51 through the mounting shaft 52. The connecting elastic element is sleeved on the mounting shaft 52, with one end assembled to the mounting bracket 51 and the other end assembled to the connecting frame 53. The guide wheel 54 is rotatably mounted on the connecting frame 53 through a shaft connection.

[0039] Furthermore, the connecting frame 53 includes two assembly parts and one connecting part. One end of the assembly part is connected to the mounting bracket 51 via the mounting shaft 52, and the other end of the assembly part is connected to a guide wheel 54. The two assembly parts are arranged in parallel and are respectively placed at both ends of the bottom side of the tray 3. The connecting part is arranged laterally and its two ends are fixed to the two assembly parts respectively.

[0040] In this application, the connecting elastic element can be a spring, providing elastic support for the connecting frame 53; the outer wall of the guide wheel 54 is covered with a buffer anti-slip layer, and the top surface of the tray 3 is provided with an anti-slip pad. The anti-slip pad and the buffer anti-slip layer can be made of rubber, which can play a role in buffering and anti-slip.

[0041] In practical applications, when it is necessary to replace the bottled water, the motor 231 is started. The motor 231 drives the worm 232 to rotate. The worm 232 drives the lead screw 21 to rotate through meshing with the worm wheel. The threaded engagement between the lead screw 21 and the mating block 22 converts the rotational motion into the linear motion of the tray 3, causing the tray 3 to slide outward along the slide rail 42 of the guide assembly 4. As the tray 3 extends out of the placement cavity, the guide wheel 54 gradually contacts the edge of the placement cavity or other supporting surfaces as the suspended portion of the tray 3 increases. At this time, the spring, which acts as a connecting elastic element, will elastically expand and contract according to the force on the tray 3, allowing the connecting frame 53 to rotate around the mounting shaft 52 at a certain angle, thereby adjusting the position and force state of the guide wheel 54. The rubber buffer and anti-slip layer covering the outer wall of the guide wheel 54 can effectively increase the friction between the guide wheel 54 and the supporting surface, preventing the guide wheel 54 from slipping during sliding, and at the same time playing a buffering role, reducing the hard collision between the guide wheel 54 and the supporting surface. The guide wheel 54 can provide additional support for the tray 3, reducing the bending deformation of the tray 3 caused by the suspended force.

[0042] After the bottled water is placed on the rubber anti-slip pad on the top surface of the tray 3, the motor 231 is restarted to reverse the motor. The tray 3, carrying the bottled water, slides inward along the slide rail 42 back to the top of the base 1. During this process, the guide wheel 54 can rotate flexibly, reducing the friction between it and the support surface. The T-shaped slider 41 and the circular track 421 are designed to maintain good stability during the sliding process. The inclined surfaces 411 on both sides of the small end of the slider 41 fit tightly against the flared opening on the top surface of the slide rail 42 support, guiding the slider 41 smoothly into the slide rail 42 and limiting the slider 41 in the horizontal direction to prevent it from deviating. This further improves the smoothness of the movement of the tray 3 and ensures the stability and reliability of the tray 3 during the movement until the tray 3 completely returns to its original position, completing the bottled water replacement process.

[0043] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
