Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, and more specifically, to a liftable water injection component and a cleaning device having the same. Background Technology

[0002] With the development of smart home technology, cleaning robots such as robotic vacuum cleaners and robotic mops have been widely used in homes and commercial settings. To achieve automated operation, cleaning robots are typically equipped with base stations to perform functions such as charging, water filling, and dust collection. Among these, the water filling function is a key element in ensuring the continuous operation of the cleaning robot.

[0003] In existing technologies, the water injection structure of base stations is mostly fixed, meaning the water inlet position is not adjustable. This design has the following drawbacks: When the cleaning robot returns to the base station, it needs to be precisely aligned with the water inlet. If there is a slight deviation in the robot's positioning (such as uneven ground or wheel wear), the water inlet and robot inlet may be misaligned, preventing water injection. Furthermore, when the fixed water inlet and robot inlet align, rigid collisions often occur due to positional deviations, which can easily cause wear on both over time, affecting sealing performance and service life. In addition, if there are tilt or horizontal errors during base station installation, the fixed water inlet and robot inlet may not align, increasing the difficulty of installation and debugging.

[0004] Therefore, there is an urgent need for a more reasonable design for the water injection component. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] This embodiment proposes a liftable water injection component. A structural schematic diagram of the base station with the water injection component is attached to the instruction manual. Figure 1-3 As shown, the specific solution is as follows:

[0030] A liftable water injection component 1 is located on an external base station 2 and connected to the water channel of the external base station 2, used for injecting water into an external cleaning robot. The position of the water injection component 1 on the base station 2 is shown in the attached figure. Figure 4As shown. The cleaning device includes a cleaning robot and a base station 2. The cleaning robot is the main device responsible for performing cleaning tasks, such as a sweeping robot, while the base station 2 is the core component for charging, cleaning, and maintaining the cleaning robot. The water injection assembly 1 includes a water inlet 11, a water pipe 12, a lifting platform 13, a drive component 14, and a support component 15. The support component 15 is connected to the external base station 2. The water pipe 12 is set on the lifting platform 13 and connected to the water circuit of the external base station 2. The water inlet 11 is located at the end of the water pipe 12 and is used to match the water inlet of the external cleaning robot. The drive component 14 is connected to the lifting platform 13. The lifting platform 13 is used to move the water pipe 12 under the drive of the drive component 14, so that the water inlet 11 is close to or away from the external cleaning robot. The water injection assembly 1 is the core functional component of the external base station 2. It is installed on the external base station 2 as a whole and is connected to the water system of the base station 2, such as a water tank and water supply pipes, through internal passages. When an external cleaning robot (such as a sweeping robot with mopping function) returns to base station 2 and needs to replenish cleaning water, it completes the water connection with the robot through its own structural actions and injects water into the robot.

[0031] The support component 15 serves as the installation foundation and structural framework for the water injection assembly 1. It is rigidly connected to the fixed structure of the external base station 2, providing a stable mounting platform for the entire water injection assembly 1 and ensuring that other components do not experience overall displacement or shaking during operation. The connection methods between the support component 15 and the external base station 2 include, but are not limited to, detachable connections and integrated connections. For example, connections can be made using screws or snap-fit ​​fasteners. Furthermore, the support component 15 must possess sufficient structural strength and can be made of materials such as plastic or metal to support the weight of components such as the lifting platform 13 and the drive component 14, as well as the forces exerted during movement.

[0032] The water inlet pipe is the physical carrier for water flow from base station 2 to the cleaning robot. One end connects to the water system of external base station 2 via an interface (such as a flexible hose connection or a rigid pipe seal connection), while the other end connects to water inlet 11, responsible for delivering water (such as clean water or cleaning solution) from base station 2 to water inlet 11. The water inlet pipe is fixed to the lifting platform 13 and moves synchronously with the lifting platform 13 to ensure that the water system remains connected and leak-free during movement. The water inlet pipe needs to have a certain degree of flexibility to prevent breakage during movement. The specific material is selected based on requirements such as water pressure and movement range, such as food-grade silicone tubing or rigid plastic tubing. Water inlet 11 is the end of the water inlet pipe 12 and is the connection point between the component and the cleaning robot. Its shape, size, and interface structure must be completely matched with the water inlet of the external cleaning robot to ensure that the water system is connected and leak-free after connection.

[0033] The lifting platform 13 serves as the mounting platform for the water injection pipe 12, integrating the water injection pipe 12 and the water inlet 11 into a movable unit. Simultaneously, it receives power from the drive unit 14, using its own displacement to move the water injection pipe 12 and the water inlet 11 synchronously. On one hand, it supports and fixes the water injection pipe 12; on the other hand, it connects to the power output end of the drive unit 14 (e.g., through bushings, connecting rod pins), and may cooperate with the guide structure on the support unit 15 to ensure stable movement. The lifting platform 13 moves the water inlet 11 closer to or further away from the cleaning robot. When the robot enters the base station 2, the lifting platform 13 moves the water inlet 11 forward to approach the robot; after water injection, it retracts backward. The drive unit 14, including motors, cylinders, and hydraulic cylinders, drives the lifting platform 13 to move in a preset direction and distance.

[0034] When the cleaning robot has not returned to base station 2, the drive unit 14 is in a reset state, and the lifting platform 13 moves the water injection pipe 12 and water inlet 11 to their initial positions away from the robot's docking location to avoid interfering with the robot's entry into base station 2. When the cleaning robot returns to base station 2 and docks, the base station 2 control system detects the robot signal and sends a start command to the drive unit 14. Upon receiving the command, the drive unit 14 starts, outputting power to move the lifting platform 13. The lifting platform 13 moves the water injection pipe 12 and water inlet 11 synchronously until the water inlet 11 precisely aligns with the robot's water inlet. After alignment, the base station 2 water system opens, and water flows through the water injection pipe 12 and water inlet 11 into the robot's water inlet, completing the water replenishment. After water replenishment, the drive unit 14 reverses its movement, moving the lifting platform 13, water injection pipe 12, and water inlet 11 back to their initial positions, separating from the robot's water inlet, awaiting the next water replenishment command.

[0035] In some specific embodiments, the support member 15 is provided with a guide part 18, and the lifting platform 13 is connected to the guide part 18. The guide part 18 is used to guide and restrict the movement of the lifting platform 13, thereby improving the stability and accuracy of the movement of the lifting platform 13. The guide part 18 is an auxiliary structure provided on the support member 15, and its specific form is not limited. Common forms include: guide rod, guide rail and slide groove, guide sleeve. If the guide part 18 is a guide rod, a through hole can be provided on the lifting platform 13, and the guide rod passes through the through hole; if the guide part 18 is a slide groove, the protrusion on the lifting platform 13 is embedded in the slide groove and can slide along the groove. The guide part 18 forces the lifting platform 13 to move in a preset direction, avoiding deviation in the direction of movement caused by uneven power of the drive member 14 or component installation errors, and constrains the degree of freedom of the lifting platform 13, ensuring that it only moves on the necessary trajectory.

[0036] In some specific embodiments, a circuit board 17 is also included. The circuit board 17 is fixedly connected to the support 15 and electrically connected to the drive unit 14 and the external base station 2. The location of the circuit board 17 is shown in the attached figure. Figure 1-3As shown. Circuit board 17 is fixedly connected to support 15, and must be kept away from waterways and facilitate wiring connections between drive unit 14 and base station 2. Circuit board 17 is the control center of the component, and may integrate microcontrollers, relays, interface circuits, etc., for processing signals and controlling drive unit 14. Circuit board 17 can receive control commands from base station 2, parse the commands, and output control signals to drive unit 14. It can also integrate position detection functions, such as detecting whether the lifting platform 13 is in position through a Hall sensor, to achieve closed-loop control.

[0037] In some specific embodiments, a waterproof rubber sleeve 16 is also included, which is disposed at the water inlet 11. The structure of the rubber sleeve 16 is shown in the attached figure. The rubber sleeve 16 is annular or cap-shaped, and is made of elastic rubber, such as silicone or nitrile rubber, possessing water resistance, flexibility, and a certain degree of abrasion resistance. When the water inlet 11 docks with the robot's sprue, the rubber sleeve 16 is compressed and deformed, filling the gap between the two. Furthermore, the elasticity of the rubber can alleviate the rigid collision when the water inlet 11 docks with the robot's sprue, reducing mechanical wear on both. The structure and position of the rubber sleeve 16 are shown in the attached figure. Figure 2 and 3 As shown

[0038] In some specific embodiments, the drive unit 14 includes a motor and a transmission unit, the transmission unit being connected to the motor and the lifting platform 13 respectively, and the transmission unit including a linkage structure. The structures of the motor and the transmission unit are shown in the attached figure. Figure 3 As shown. The motor, as a power source, converts electrical energy into rotational mechanical energy. This includes DC motors, stepper motors, etc., providing the initial power for the movement of the lifting platform 13. The transmission unit, acting as a power transmission intermediary, connects the motor's output end and the lifting platform 13, responsible for converting the motor's rotational motion into the linear or curvilinear motion of the lifting platform 13. The linkage structure is a transmission mechanism composed of several rigid rods connected by hinges. Its basic principle is: the motor drives one rod, and through the hinge relationship between the rods, the rotational motion is converted into the swinging or linear motion of another rod; ultimately, the driven rod pushes or pulls the lifting platform 13, realizing its movement towards / away from the robot. The combination of the motor and the linkage structure is suitable for the low-power, small-space requirements of smart home scenarios. The linkage structure has a fixed transmission ratio, and the moving distance of the lifting platform 13 can be precisely controlled by designing the rod length to meet docking accuracy requirements. Furthermore, the structure is simple, easy to process, and suitable for mass production, reducing component manufacturing costs.

[0039] In some specific embodiments, the linkage structure includes a transmission rod and a rotating rod; a motor is connected to the rotating rod to drive its rotation; the transmission rod connects the rotating rod and the lifting platform 13, and is used to rotate around the rotating rod as an axis to realize the movement of the lifting platform 13. The rotating rod is a rigid rod directly connected to the motor, with one end fixed to the motor's output shaft, and can rotate around its own axis under the motor's drive, with the motor shaft as the center of rotation. The transmission rod is an intermediate rod connecting the rotating rod and the lifting platform 13, with both ends movably connected to the rotating rod and the lifting platform 13 respectively via hinges. Through the simple combination of the rotating rod and the transmission rod, the efficient conversion from rotational motion to linear motion is achieved, and the moving distance of the lifting platform 13 is precisely controlled.

[0040] In some specific embodiments, the support member 15 is provided with a notch 19, through which the water injection pipe 12 connects to the water channel of the external base station 2. The notch 19 is a groove-like or hole-like structure formed on the support member 15, and its position must correspond to the connection point between the water injection pipe 12 and the water channel of the base station 2, typically on the side of the support member 15 closer to the interior of the base station 2. The size of the notch 19 must be slightly larger than the outer diameter of the water injection pipe 12 to ensure that the water injection pipe 12 can pass through and has sufficient room to move, preventing the water injection pipe 12 from being squeezed and deformed by the support member 15 when the lifting platform 13 moves. The location of the notch 19 is shown in the attached figure. Figure 2 and 3 As shown.

[0041] In some specific embodiments, the guide part 18 is one or more guide rods, and the lifting platform 13 is provided with a through hole. The guide rods extend into the through hole to restrict the movement of the lifting platform 13. The guide rods are rigid rod-shaped structures, such as metal round rods or plastic square rods. The guide rods need to have a certain degree of straightness and surface smoothness to reduce friction with the lifting platform 13. When the lifting platform 13 moves, the through hole slides along the guide rod, forcing the lifting platform 13 to move only along the axial direction of the guide rod (such as vertical up and down or horizontal back and forth), avoiding deviation; a single guide rod can restrict the rotation of the lifting platform 13 and the movement perpendicular to the rod axis; multiple guide rods can completely constrain the excess degrees of freedom of the lifting platform 13, preventing tilting or shaking.

[0042] A cleaning device includes a base station 2 and a cleaning robot. The base station 2 is equipped with a water injection component 1 as described above, and the cleaning robot is equipped with a water inlet that matches the water injection port 11. The base station 2 injects water into the cleaning robot through the water injection component 1. The base station 2 is shown in the attached diagram. Figure 5As shown. Base station 2 is a resupply station for the cleaning robot, integrating a water system (such as a water tank, water pump, solenoid valve, etc.) and a control system, and is equipped with the aforementioned water injection component 1. The cleaning robot is a mobile device with cleaning functions (such as sweeping and mopping), and its body is equipped with a water inlet (for receiving water injected by base station 2), and it usually has a water storage tank inside. The robot's water inlet and the water injection port 11 of the base station 2's water injection component 1 are complementary in shape and size, such as a convex head-concave fit, to ensure water flow after docking. After the robot completes the cleaning task, it autonomously returns to base station 2. After base station 2 detects the robot's arrival through sensors, it controls the water injection component 1 to move, and the lifting platform 13 moves the water injection port 11 to dock, then opens the water channel to inject water into the robot. After completion, the water injection component 1 resets.

[0043] In some specific embodiments, a one-way valve is provided at the water inlet. Adding a one-way valve at the water inlet of the cleaning robot optimizes the backflow prevention performance after water filling. The one-way valve is integrated inside the water inlet of the cleaning robot and is a valve that only allows fluid to flow in one direction, such as a spring-loaded one-way valve or a diaphragm one-way valve. During water filling, the water pressure at the water inlet 11 of base station 2 pushes the valve disc to open, and water flows into the robot's water storage tank. After water filling is completed, the valve disc closes under the action of spring force or its own gravity, preventing backflow of water in the water storage tank.

[0044] This utility model provides a liftable water injection component and a cleaning device with it. The water injection port can actively move closer to or further away from the water inlet of the cleaning robot, reducing the requirements for the robot's return accuracy, achieving precise docking, simplifying the installation and debugging process, and the structural design facilitates disassembly and maintenance, reducing the later maintenance cost.
