Description

Technical Field

[0001] This utility model relates to cleaning robot technology, and more particularly to a water supply device for a cleaning robot. Background Technology

[0002] In the field of cleaning robots, especially those with wet cleaning capabilities, the water supply system directly affects the robot's cleaning efficiency and battery life. The limited internal space of cleaning robots generally restricts the volume of their water tanks. When cleaning large areas, frequent interruptions are necessary to replenish clean water or empty wastewater, severely impacting the automation and continuity of the cleaning process. Traditional solutions simply increase the water tank size, but this runs counter to the trend of miniaturization and lightweight design in robots.

[0003] Early or simpler models of robots used single-chamber water tanks or had inadequate designs for separating clean and wastewater. This can easily lead to wastewater back-contaminating the clean water tank during the recycling process, affecting cleaning effectiveness and potentially causing secondary contamination of the surface to be cleaned by using contaminated water for spraying.

[0004] Water circulation can solve the problem of frequent water replenishment. Traditional filtration systems are bulky and difficult to integrate into compact robotic water tanks. Simple filters cannot effectively remove fine impurities, oil, and flocculent matter from the water, and these impurities will quickly clog the water supply pipes and nozzles.

[0005] Therefore, there is a need for further improvement of the existing technology. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Reference Figures 1 to 6 As shown, this embodiment proposes a water supply device for a cleaning robot, including a lower bottom shell unit 10, an upper bottom shell unit 20, and a cleaning unit 30.

[0023] The cleaning unit 30 is installed outside the upper bottom shell unit 20, and the lower bottom shell unit 10 is equipped with a drive device for controlling the movement of the cleaning robot.

[0024] Preferably, the driving device is a roller, or it may be a roller driven by a motor.

[0025] Furthermore, the upper bottom shell unit 20 includes an upper bottom shell 21, a cover 22, a water tank assembly 23, and a water supply component 24. The water tank assembly 23 is installed inside the upper bottom shell 21, the water supply component 24 is connected to the bottom of the water tank assembly 23, and the cover 22 is installed on the top of the upper bottom shell 21.

[0026] The cleaning unit 30 consists of a water spraying rod 31 and a water suction rod 32. The water spraying rod 31 is used to spray the cleaning water in the water tank assembly 23 outward; the water suction rod 32 is used to suck external sewage into the water tank assembly 23.

[0027] In this embodiment, refer again Figures 3 to 6As shown, the water tank assembly 23 has a tank body 231, and the top of the tank body 231 has a hinged cover 232. The cover 232 is provided with a handle 233. By pulling the handle 233, the cover 232 is rotated along its hinge point to open the tank body 231.

[0028] The outer side of the housing 231 is provided with a mounting bracket 234, and the housing 231 is snapped into the interior of the upper bottom outer shell 21 via the mounting bracket 234.

[0029] Specifically, a partition 235 is installed inside the housing 231, dividing the housing 231 into a clean water area and a wastewater area. An absorbent sponge 236 is installed on the top of the wastewater area, and a first interface 237 is provided on the outside of the housing 231 at a position corresponding to the wastewater area. This first interface 237 is connected to the absorbent rod 32.

[0030] The wastewater area is also equipped with a filter element 238, which extends from the inside of the housing 231 to its outside. See [specific details]. Figures 5 to 6 As shown.

[0031] In this embodiment, the suction boom 32 draws the wastewater generated after cleaning into the wastewater zone of the water tank assembly 23. The wastewater zone is equipped with an absorbent sponge 236 for rapid absorption and temporary storage of wastewater, preventing overflow. The wastewater zone also features a filter element 238 extending from the inside of the tank to the outside, which filters the drawn-in wastewater, removing solid impurities and particulate matter. The filtered water may be recycled for further cleaning or stored in the wastewater zone for subsequent treatment.

[0032] Furthermore, an arc-shaped cavity 239 is provided inside the water purification area, which is used to store disinfectant or cleaning agent. A second interface 2310 is provided at a position opposite to the water purification area and the arc-shaped cavity 239, and this second interface 2310 is connected to the spray lever 31.

[0033] In this embodiment, the water tank assembly 23 stores clean water in its clean water zone and delivers the water to the spray boom 31 via the water supply component 24. An arc-shaped cavity 239 is provided within the clean water zone for storing disinfectant or cleaning agent. The disinfectant can be mixed with the clean water and sprayed together to enhance the cleaning effect. When the cleaning robot is running, the spray boom 31 sprays the mixed clean water onto the surface to be cleaned for wet cleaning or disinfection. The water supply component 24 controls the water pressure and flow rate to ensure uniform spraying.

[0034] Because other components need to be installed inside the cleaning robot, the housing 231 is relatively small. During cleaning, it requires repeated treatment of wastewater or addition of cleaning water, which is quite cumbersome.

[0035] Therefore, the wastewater discharged from the filter element 238 is recycled back into the clean water area via the water supply component 24. The water supply component 24 consists of a pump, multiple pipes, and multiple solenoid valves, enabling switching and stable supply of multiple liquids. This is existing technology and will not be described in detail here.

[0036] The water purification zone is provided with a third interface 2312, which is connected to the end of the filter element 238 through the water supply component 24, and is used to connect the water purification zone and the sewage zone.

[0037] Preferably, both the clean water zone and the wastewater zone are equipped with filter partitions 2311, which are installed in one corner of the clean water zone or the wastewater zone. Activated carbon packets are placed inside the filter partitions 2311 to absorb odors from the water in the clean water zone or the wastewater zone.

[0038] In this embodiment, during the cleaning operation, the suction boom 32 draws wastewater from the ground into the wastewater area of ​​the water tank assembly 23. The wastewater is first initially absorbed and temporarily stored by the absorbent sponge 236 to prevent overflow. Subsequently, driven by the water supply component 24, the wastewater is filtered through the filter element 238 to remove solid impurities, particulate matter, and suspended solids. The filtered clean water is then pumped back into the clean water area, mixed with the existing clean water, and used again by the spray boom 31. This closed-loop system allows the cleaning robot to work for an extended period after a single refill without the need for intermediate water replenishment or drainage.

[0039] Disinfectant or cleaning agent only needs to be added periodically to the arc-shaped cavity 239 in the water purification zone. The disinfectant or cleaning agent automatically mixes with the purified water during the water supply process and is evenly sprayed onto the surface to be cleaned via the spray nozzle 31, thereby improving the cleaning effect and achieving the disinfection function. The arc-shaped cavity 239 ensures the slow release of the additive, avoiding uneven concentration caused by one-time mixing.

[0040] Filter cartridge 238 needs to be replaced regularly to prevent clogging from affecting filtration efficiency and water flow rate. Additionally, the activated carbon packets placed in the filter baffles 2311 in both the clean water and wastewater zones also need to be replaced regularly to continuously absorb odors and maintain water quality. Other components, such as the absorbent sponge 236, can be cleaned or replaced as needed.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
