Description
Technical Field
[0001] This utility model relates to cleaning robot technology, and more particularly to an atomizing nozzle device for a cleaning robot. Background Technology
[0002] With the rapid development of smart home technology, cleaning robots have been widely used in daily cleaning work in homes and commercial environments. Traditional cleaning robots mainly clean by using roller brushes, vacuuming, or wiping with damp cloths. However, when faced with complex geometric structures, such as toilet bowl linings, narrow crevices, and vertical surfaces, they suffer from uneven cleaning coverage, difficulty in reaching hard-to-reach areas, and low cleaning efficiency. In addition, most existing cleaning robots lack disinfection functions, making it difficult to effectively kill bacteria and viruses, and thus failing to meet the needs of scenarios with high hygiene requirements.
[0003] Currently, while some cleaning robots on the market are equipped with water spraying devices, they mostly use direct spraying or splashing methods, resulting in low liquid utilization, water accumulation, or waste of cleaning fluid. Furthermore, they cannot achieve fine atomization, affecting cleaning effectiveness. At the same time, traditional nozzles are often fixed in place, limiting their application range due to the inability to flexibly adjust their angle and position. Therefore, there is an urgent need in this field for a cleaning robot nozzle device that combines atomization spraying, flexible movement, quick assembly / disassembly, and disinfection functions to improve cleaning efficiency and hygiene levels. Utility Model Content

Detailed Implementation
[0019] 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.
[0020] Reference Figures 1 to 8 As shown, this embodiment proposes an atomizing nozzle device for a cleaning robot, comprising a housing unit 10, a robotic arm unit 20, and an atomizing nozzle unit 30. The robotic arm unit 20 is mounted on one side of the housing unit 10, and the atomizing nozzle unit 30 is detachably connected to the robotic arm unit 20. The detachable connection can be a snap-fit connection, a bolt connection, or a magnetic connection.
[0021] Furthermore, the robotic arm unit 20 consists of a mechanical swing arm 21 and a connecting end 22. The connecting end 22 is located at one end of the mechanical swing arm 21.
[0022] In this embodiment, the atomizing nozzle unit 30 includes a water storage tank 31, and a conduit 32 is installed at one end of the water storage tank 31. A pump body 33 is mounted on the conduit 32, and the pump body 33 is connected to one end of a throttle valve 34 via another conduit 32. The other end of the throttle valve 34 is connected to the atomizing nozzle assembly 36 via a water supply pipe 35.
[0023] Furthermore, in this embodiment, the atomizing nozzle assembly 36 and the connecting end 22 are connected magnetically. Specifically, refer again... Figures 7 to 8 As shown, the atomizing nozzle assembly 36 includes an end block 361, and the end block 361 is provided with an electromagnetic suction block 362. The connecting end 22 is provided with the same electromagnetic suction block 362 as the end block 361, and the connection is achieved by the mutual attraction of the two electromagnetic suction blocks 362.
[0024] In this embodiment, a flange 364 is provided at the end of the end block 361 away from the electromagnetic suction block 362, and a rod 365 is connected to the other end of the flange 364. A water supply chamber 367 is provided on one side of the rod 365, and the water supply chamber 367 is connected to the water supply pipe 35.
[0025] Preferably, a metal strap 363 is provided above the end block 361. The metal strap 363 is snapped onto the outer wall of the water supply pipe 35 to constrain one end of the water supply pipe 35 to adhere to the atomizing nozzle assembly 36, preventing the water supply pipe 35 from falling off the water supply chamber 367 during disassembly.
[0026] The rod 365 is provided with a nozzle 366 at the end away from the flange 364, and a disinfection lamp 368 is provided above the nozzle 366.
[0027] In this embodiment, after receiving a cleaning command, the mechanical arm 21 begins to work, driving the end connector 22 and the entire atomizing nozzle unit 30 to move. The mechanical arm 21 can flexibly extend, bend, and rotate, accurately delivering the atomizing nozzle to the location that needs cleaning, overcoming the limitations of traditional cleaning robots in handling complex geometric spaces.
[0028] Pump 33 starts, drawing cleaning fluid or clean water from water tank 31. The liquid flows through throttle valve 34, which is used to precisely control the flow rate and pressure of the liquid to ensure the formation of stable and fine droplets.
[0029] The pressure-regulated liquid is delivered to the atomizing nozzle assembly 36 through the water supply pipe 35. The liquid is then sprayed out from the nozzle 366 in the form of high-speed atomization. The atomization technology can break down the liquid into micron-sized water droplets, forming a fine water mist with wide coverage and uniform adhesion.
[0030] The atomizing nozzle assembly 36 is magnetically connected to the robotic arm via an electromagnetic chuck 362. When connection is required, the electromagnets on the connecting end 22 and the end block 361 are energized, generating magnetic force that attracts and secures them together. When nozzle replacement or maintenance is required, the magnetic force is lost by disconnecting the power, allowing for easy separation.
[0031] Metal straps 363 are used to secure the water supply pipe 35, preventing it from falling off during frequent movement or disassembly of the robotic arm and ensuring the reliability of the water supply.
[0032] Simultaneously or immediately after the cleaning mist is sprayed, the disinfection lamp 368 is activated; it is typically a UV-C ultraviolet lamp. The ultraviolet light directly irradiates the cleaned surface, destroying the DNA / RNA of bacteria and viruses, preventing them from multiplying, thus achieving a sterilization and disinfection effect.
[0033] Furthermore, refer to again Figures 4 to 6 As shown, the pump body 33 includes an outlet port 331, a pump body 332, and an inlet port 333. A pressure boosting component 334 is installed inside the pump body 332. The pressure boosting component 334 includes a large ring 334A and a small ring 334B, which are engaged by a retaining ring 334C.
[0034] When pump body 33 is operating, water flows into pump body 332 and acts on the large ring 334A. The large ring 334A begins to move under water pressure. Due to its large cross-sectional area, even with a low input pressure, it generates a large total thrust. Under this strong thrust, the small ring 334B compresses the water in a sealed chamber at its front end. Because the cross-sectional area of the small ring 334B is smaller than that of the large ring 334A, the acting surface decreases while the thrust remains constant, resulting in an increase in output pressure. Ultimately, the increased water pressure is discharged from the outlet 333 and delivered to the downstream throttle valve and nozzle.
[0035] The throttle valve 34 consists of a connecting buckle 341, a valve body 342, and an electrically controlled butterfly valve 343.
[0036] In this embodiment, when applied to a toilet cleaning scenario: When pump 33 operates, it sprays the cleaning solution mixed with descaling agent evenly through nozzle 366 onto the entire inner wall of the toilet, below the water seal, and around the drain outlet. The atomized droplets adhere better to vertical surfaces and crevices, effectively dissolving dirt and urine stains.
[0037] The robotic arm moves the spray nozzle along an S-shaped or circular path along the inner wall of the toilet. After spraying, or during another cleaning cycle, the robotic arm irradiates the area that was just cleaned with a disinfection lamp 368 to kill common pathogens such as E. coli and Staphylococcus aureus.
[0038] The robotic arm adjusts its angle and sprays and disinfects areas prone to dirt accumulation, such as under the toilet seat, hinge gaps, and the base of the toilet's outer wall.
[0039] Furthermore, for stubborn stains, the robotic arm can control the throttle valve 34 to increase the flow rate and pressure for targeted rinsing.
[0040] Preferably, the nozzle 366 can switch between two modes: rinsing and spraying. For heavily soiled areas, the rinsing mode is activated for powerful flushing; for the entire inner wall or lightly soiled areas, the spraying mode is activated.
[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.
