Description

Technical Field

[0001] This utility model belongs to the field of cleaning robots, and specifically relates to a cleaning robot base station. Background Technology

[0002] Currently, mainstream high-end base stations employ advanced sensing and communication technologies to support precise docking and functional execution between robots and base stations. For example, automatic dust collection systems can suck dust from the robot's dustbin into the base station's large-capacity dust bag, reducing the frequency of manual cleaning. Some high-end models also feature automatic mop washing and drying functions, ensuring mop cleanliness and preventing bacterial growth. High-end robotic vacuum cleaner base stations significantly optimize the cleaning experience and equipment maintenance efficiency through automation technology, but some shortcomings exist; the evaporation of hot air and water vapor is more noticeable. The base station generates significant operating noise during operation (automatic dust collection, mop washing). There is also the issue of the robotic vacuum cleaner's own "self-cleaning" as a cleaning tool. While robotic vacuum cleaners can keep floors clean, they are constantly exposed and easily accumulate dust, requiring manual cleaning by the user. However, due to their low profile close to the ground, they are not frequently cleaned, inevitably leaving users with the impression that "the cleaning machine is not clean." Patent application CN222676111U is a design for a standalone robot storage compartment with a built-in sliding door that allows the robot to fully enter and close the door, such as during cleaning, drying, or dust collection operations, to close the opening and reduce noise interference; however, its door opening method will take up a lot of space. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning robot base station that is low in noise and does not take up much space when the door is opened.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a cleaning robot base station, comprising a shell and a robot compartment. The robot compartment includes a lower compartment disposed on the shell and located below the intermediate compartment, a lower compartment door for opening or closing the lower compartment, and a compartment door drive unit for driving the lower compartment door to open or close. The front side of the lower compartment is open, and lower sliding grooves extending from vertical to horizontal are formed on both the left and right sides. The lower compartment door includes a plurality of lower door panels that are flexibly connected or hinged in sequence, and a lower sliding groove installed in the shell. The lower sliding groove includes a vertical part and a horizontal part. The lower door panels are installed on the lower sliding groove. When all the lower door panels are horizontally disposed on the horizontal part, the lower compartment is open. When all the lower door panels are located in the vertical part, all the lower door panels are vertically disposed at the open front side of the lower compartment, at which time the lower compartment is closed.

[0005] In another embodiment, the lower slide groove is formed on the left and right sides of the lower compartment body. The lower compartment door also includes pulleys disposed on the left and right sides of the lower door panel. The pulleys are slidably connected in the lower slide groove. When all the pulleys are located in the horizontal part of the lower slide groove, all the lower door panels are horizontally disposed in the lower compartment body, and the lower compartment body is open. When all the pulleys are located in the vertical part of the lower slide groove, all the lower door panels are vertically disposed on the front side of the lower compartment body in an open position, and the lower compartment body is closed.

[0006] In another embodiment, the vertical and horizontal portions of the lower groove transition in an arc shape.

[0007] In another embodiment, the door drive unit includes a linear motor fixed inside the lower compartment and located at the top of the lower compartment. The worktable of the linear motor is connected to one of the lower door panels. The two extreme positions of the linear motor correspond to the two states of the lower compartment being open and closed, respectively.

[0008] In another embodiment, the housing is provided with a box, which includes a clean water box for storing clean water and a wastewater box for storing wastewater, and a rag cleaning module is provided in the lower compartment.

[0009] In another embodiment, the rag cleaning module is equipped with a clean water tank. The clean water tank is connected to the robot's built-in water tank through a first pipeline and to the rag cleaning module through a second pipeline. The first pipeline and the second pipeline are equipped with a clean water solenoid valve and a clean water pump.

[0010] In another embodiment, the lower compartment is equipped with a dehumidification module, the rag washing module is equipped with a wastewater recovery compartment, the wastewater tank is connected to the dehumidification module through a third pipeline and to the wastewater recovery compartment through a fourth pipeline, and the third and fourth pipelines are equipped with a wastewater solenoid valve and a wastewater pump.

[0011] In another embodiment, the lower compartment is provided with waterproof sound-absorbing cotton.

[0012] In another embodiment, a waterproof ultraviolet LED lamp array is evenly distributed within the lower compartment; the ultraviolet LED lamp array is embedded in the waterproof sound-absorbing cotton.

[0013] In another embodiment, the lower compartment is provided with a partition plate, which divides the lower compartment into a front lower compartment and a rear lower compartment. The dehumidification module is located in the rear lower compartment and has an air inlet and an air outlet. The air inlet of the dehumidification module is connected to the front lower compartment, and the air outlet of the dehumidification module is located in the rear lower compartment. The rear lower compartment is provided with a hot air fan, a hot air duct connected to the hot air fan at one end, and a heating module located on the hot air duct. The other end of the hot air duct is connected to the partition plate and is connected to the front lower compartment. The moisture in the front lower compartment is dehumidified by the dehumidification module and then enters the rear lower compartment. The hot air fan heats the dehumidified gas in the rear lower compartment through the heating module and then sends it into the front lower compartment, thus completing the gas heating and dehumidification in the front lower compartment.

[0014] The beneficial effects of this invention are as follows: The fully enclosed robot cabin conceals the internal structure and the robot during maintenance. The combination of a fully enclosed lower compartment and sound-absorbing cotton significantly reduces noise generated during mop cleaning and mobile phone dust collection. When drying the mop, the fully enclosed cabin allows hot air to circulate within the cavity without continuously dissipating outwards, effectively improving drying efficiency. Simultaneously, any odors carried by the mop are prevented from spreading with the hot air. With the help of a moisture collection system, the base station can collect moisture from the cavity and send it to the wastewater tank to ensure drying efficiency. The ultraviolet sterilization module effectively kills bacteria. The fully enclosed cabin, while ensuring safety, utilizes a high-power ultraviolet module to comprehensively cover the interior of the cabin, effectively disinfecting the mop and every corner of the cabin, ensuring better sterilization and effectively controlling hygiene hazards and odor problems caused by bacterial growth.
