Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to a cleaning device. Background Technology
[0002] Household appliances, or home appliances for short, refer to various appliances used in the home environment that provide convenience and improve the quality of life for people. In daily life, when dust, hair, debris, and other debris appear on the indoor floor, a vacuum cleaner can quickly and effectively remove them. For example, if someone in the household is experiencing severe hair loss, there will be a lot of hair on the floor, which is troublesome to clean manually, but a vacuum cleaner can easily solve this problem.
[0003] A search revealed Chinese patent publication number CN215383652, which discloses a cleaning head and a cleaning device. The cleaning head includes a body and a brush roller. The body has a chamber suitable for accommodating the brush roller, which can rotate or move relative to the body within the chamber. The chamber includes opposing air inlets and outlets. The cleaning head further includes an air duct communicating with the chamber through the air outlet. The chamber and the air duct converge at the air outlet to form a narrow, elongated transition section. This invention improves the cleaning effect and efficiency of the cleaning device, particularly its ability to clean hair. The device itself is easy to maintain, as hair rarely gets tangled on the brush roller, eliminating the need for manual cleaning by the user.
[0004] While the aforementioned solution mentions the beneficial effects of "the vacuum cleaner head effectively removing hair adsorbed and remaining on the surfaces of woven fabrics, textiles, carpets, and other materials, especially suitable for removing hair remaining on the surface of clothing worn on the body. Furthermore, the removed hair can be directly sucked into the vacuum cleaner's trash can by the conductive hose connected to the rear end of the cleaning head, and the brush roller of the cleaning head itself remains clean, requiring no further cleaning," although the above solution effectively removes hair adsorbed and remaining on the surfaces of woven fabrics, textiles, carpets, and other materials, the existing technology has the problem that the side brush is difficult to disassemble. During the cleaning process, the side brush is prone to getting tangled with hair, threads, and various fine dust and debris. If the side brush is difficult to disassemble, the user cannot perform a comprehensive and in-depth cleaning. Over time, more and more dirt accumulates on the side brush, which not only affects the normal rotation of the side brush, making it difficult to effectively clean corners, edges, and other edge areas, but also easily causes dirt to be repeatedly carried to the cleaned floor, causing secondary pollution and seriously reducing the quality and cleanliness of the cleaning effect. Therefore, a cleaning device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a cleaning device that aims to improve the problem in the prior art where the side brush is difficult to disassemble, which easily leads to dirt being repeatedly carried to the cleaned floor.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cleaning device includes a housing, with walking mechanisms fixedly connected to both the left and right sides inside the housing, a side brush mechanism fixedly connected to the front inside of the walking mechanisms, a brush rotatably connected inside the housing, a steam module disposed inside the housing, a drying mechanism fixedly connected to the rear inside of the housing, a secondary cleaning mechanism fixedly connected to the rear inside of the housing, a filter screen fixedly connected inside the housing, a solid-liquid separation chamber opened inside the rear inside of the housing, an anti-collision sensor fixedly connected to the front of the housing, a control module fixedly connected inside the housing, and a battery fixedly connected inside the housing.
[0008] The side brush mechanism includes a second motor, which is externally and fixedly connected to the inside of the housing. A rotating column is fixedly connected to the drive end of the second motor. A sleeve is detachably connected to the outside of the rotating column. Multiple side brushes are fixedly connected to the outside of the sleeve. Square openings are provided on the left and right sides inside the rotating column. Rotating shafts are rotatably connected to the front and rear sides inside the square openings. Rotating plates are fixedly connected to the outside of the rotating shafts. Two springs are fixedly connected to the adjacent sides of the two rotating plates. Pressing rods are slidably connected to the left and right sides inside the sleeve. Pressing plates are fixedly connected to the adjacent sides of the two pressing rods.
[0009] The above technical solution involves: a walking mechanism to move the equipment; a side brush mechanism to clean edge debris, with the side brush being detachable and replaceable; a brush for deep cleaning; a steam module to soften stubborn stains; a drying mechanism to prevent water stains on the ground; a secondary cleaning mechanism to further remove fine impurities; a filter screen and a solid-liquid separation chamber to treat wastewater impurities; an anti-collision sensor working with the control module to ensure operational safety; and a battery to provide power.
[0010] As a further description of the above technical solution:
[0011] The walking mechanism includes a housing, the outside of which is fixedly connected to the inside of the housing. A motor is fixedly connected to the inside of the housing. A gear is fixedly connected to the drive end of the motor. A rotating rod is rotatably connected to the inside of the motor. A gear is fixedly connected to the outside of the rotating rod. Rotating rods are rotatably connected to the left and right sides inside the housing. A gear is fixedly connected to the outside of the rotating rod. A wheel is fixedly connected to the outside of the rotating rod. A caster wheel is rotatably connected to the inside of the housing.
[0012] The above technical solution involves a motor driving a gear to rotate. The meshing of gear one with gears two and three transmits power to rotating rods one and two, thereby driving the wheels to rotate and providing forward power for the cleaning equipment. At the same time, the casters can rotate flexibly, enabling the equipment to steer flexibly. This allows the cleaning equipment to move stably and conveniently in different ground environments, meeting diverse cleaning path requirements.
[0013] As a further description of the above technical solution:
[0014] The steam module includes a water storage cavity, the exterior of which is opened inside the shell. A partition is fixedly connected to the inner wall of the water storage cavity, a water pump is fixedly connected to the top of the partition, a fixed plate is fixedly connected to the top of the shell, the output end of the water pump is connected to the bottom of the fixed plate through a pipe, and multiple steam nozzles are fixedly connected to the bottom of the fixed plate.
[0015] Through the above technical solution, the steam module achieves the function of steam cleaning the ground. The water storage chamber stores cleaning water, and the water pump draws water from the water storage chamber and transports it to the fixed plate through pipes. Steam is sprayed out from multiple steam nozzles at the bottom of the fixed plate. The steam can soften stubborn stains on the ground. In conjunction with other cleaning components, it improves the cleaning efficiency and quality of the cleaning equipment.
[0016] As a further description of the above technical solution:
[0017] The drying mechanism includes a fixed box, the outside of which is fixedly connected to the rear inner side of the housing, a fan is fixedly connected to the bottom inner wall of the fixed box, and a heating rod is fixedly connected to the inside of the fixed box.
[0018] The above technical solution achieves the function of drying the floor after steam cleaning. The mounting box provides installation space for the fan and heating rod and prevents hot air leakage. The fan blows air towards the heating rod, which is powered on and heats up the air. The hot air is then blown out of the mounting box, quickly evaporating any residual water stains on the floor, preventing the floor from becoming damp, ensuring the floor is dry after cleaning, and improving the overall cleaning effect.
[0019] As a further description of the above technical solution:
[0020] The secondary cleaning mechanism includes a square box. Fixed frames are fixedly connected to the left and right sides of the inside of the square box. Long openings are provided on the front and rear sides of the inside of each fixed frame. Square rods are slidably connected inside the long openings. Rotating columns are fixedly connected to the outside of the two square rods. Rollers are rotatably connected to the outside of the rotating columns. Support columns are fixedly connected to the left and right sides of the inside of the square box. Sliding blocks are slidably connected inside the support columns. A sliding rod is fixedly connected to the top of each sliding block. Two springs are fixedly connected to the left and right sides of the inside of the square box.
[0021] The above technical solution achieves deep cleaning of the floor. The fixed frame inside the square box provides sliding space for the square rod through the long slot, allowing the rotating column and roller to move up and down according to the floor conditions. The support columns on both sides of the square box, together with the sliding block and sliding rod, and the second spring, provide buffering and adaptive adjustment for the rotating column, ensuring that the roller is in close contact with the floor, further removing the fine stains left after steam cleaning and brush cleaning, and improving the thoroughness of floor cleaning.
[0022] As a further description of the above technical solution:
[0023] The top of the sliding block is fixedly connected to the bottom of the sliding rod, and the tops of the two springs are fixedly connected to the bottom left and right sides of the rotating column.
[0024] The above technical solution involves connecting the sliding block to the sliding rod. When the roller encounters an uneven surface, the rotating column drives the sliding rod to move the sliding block. Spring 2 connects to both sides of the bottom of the rotating column, playing a buffering and adjusting role at this time, either compressing or extending to ensure that the roller can always closely fit the ground, improving the adaptability of secondary cleaning to complex ground conditions, effectively removing residual stains, and improving the cleaning effect.
[0025] As a further description of the above technical solution:
[0026] The two pressing plates are in contact with the two rotating plates on opposite sides, the outer side of the rotating plates is engaged with the inner side of the sleeve, and the adjacent sides of the multiple springs are fixedly connected to the inner wall of the square opening.
[0027] The above technical solution allows for the following: When installing the side brush, the spring pushes the rotating plate to engage inside the sleeve, ensuring a secure connection. When disassembling, pressing the pressing plate squeezes the rotating plate, causing it to disengage from the sleeve and overcome the spring force, thus facilitating the quick and easy disassembly of the side brush. This makes it easier to replace and maintain the side brush, ensuring long-term efficient cleaning by the side brush mechanism.
[0028] As a further description of the above technical solution:
[0029] The outer surfaces of gear one and gear two are meshed together, and the outer surfaces of gear one and gear three are meshed together.
[0030] Through the above technical solution: motor one drives gear one to rotate, and through the meshing relationship, the power is synchronously transmitted to gear two and gear three respectively connected to rotating rod one and rotating rod two, so that rotating rod one and rotating rod two drive the wheel to rotate, driving the cleaning equipment to move, while ensuring the power balance and stability during the movement of the equipment.
[0031] This utility model has the following beneficial effects:
[0032] 1. In this utility model, pressing the pressing rod pushes the pressing plate to squeeze the rotating plate. The rotating plate rotates around the rotating shaft and compresses the spring, causing the rotating plate to disengage from the sleeve. This allows the sleeve and side brush to be removed from the rotating column, thus achieving the disassembly of the side brush. This ensures that all parts of the side brush can be effectively cleaned, preventing dirt from accumulating and corroding the side brush over time, thereby extending the service life of the side brush, reducing the frequency of replacing the entire cleaning equipment due to side brush damage, and lowering operating costs.
[0033] 2. In this utility model, the roller drives the rotating column to move, and the rotating column drives the sliding rod to move inside the support column. The rotating column compresses the spring, realizing the adaptive adjustment of the roller, thereby improving the effect of secondary cleaning, effectively removing dust, debris and stains hidden inside, and ensuring deep cleaning.

[0050] Reference Figure 4The steam module 5 includes a water storage chamber 51, the exterior of which is located inside the housing 1. A partition 52 is fixedly connected to the inner wall of the water storage chamber 51, and a water pump 53 is fixedly connected to the top of the partition 52. The partition 52, fixed to the inner wall of the water storage chamber 51, provides a certain degree of separation and stability for the water in the water storage chamber 51, which helps the water pump 53 to pump water more efficiently. A heating plate is fixedly connected inside the partition 52 to heat the water source, thereby improving cleaning efficiency. The water pump 53 is installed on top of the partition 52. After startup, the water in the water storage chamber 51 is extracted and transported to the fixed plate 54 through a pipe to provide water flow power for steam generation. The fixed plate 54 is fixedly connected to the top of the housing 1. The output end of the water pump 53 is connected to the bottom of the fixed plate 54 through a pipe. Multiple steam nozzles 55 are fixedly connected to the bottom of the fixed plate 54.

[0051] Specifically, it achieves the function of steam cleaning the ground. The water storage chamber 51 stores cleaning water, and the baffle 52 on its inner wall separates and stabilizes the water, helping the water pump 53 to pump water efficiently. After the water pump 53 starts, it draws water out of the water storage chamber 51 and transports it to the fixed plate 54 through the pipeline. The heating plate inside the baffle 52 heats the water, turning it into steam. The fixed plate 54 serves as the mounting carrier for the steam nozzles 55 and the connecting component for the water pump output pipeline, ensuring that steam is evenly sprayed from multiple steam nozzles 55, softening stubborn stains on the ground and greatly improving the cleaning efficiency of the cleaning equipment.
[0052] Reference Figure 2 The drying mechanism 6 includes a fixed box 61, which is externally fixedly connected to the inner rear of the housing 1. A fan 62 is fixedly connected to the inner bottom wall of the fixed box 61, and a heating rod 63 is fixedly connected to the inside of the fixed box 61. The fixed box 61 is fixed to the inner rear of the housing 1, providing installation space for the fan 62 and the heating rod 63, and also serving a protective function to prevent internal hot air leakage, ensuring that the drying work is concentrated and efficient. The heating rod 63 is fixed inside the fixed box 61 and heats up after being powered on, heating the air blown by the fan 62. The generated hot air is blown out from the fixed box 61 to dry the steam-cleaned ground and prevent water stains from remaining on the ground.
[0053] Specifically, it achieves the function of drying the floor after steam cleaning. The fixing box 61 is fixed to the inner rear of the housing 1, providing a stable installation space for the fan 62 and the heating rod 63, while effectively protecting them from hot air leakage and ensuring efficient drying. After the fan 62 is started, it blows air into the fixing box 61. The heating rod 63 is energized and heats up, quickly heating the blown air. The heated air is blown out from the fixing box 61 and precisely acts on the floor after steam cleaning, quickly evaporating residual water stains and preventing the floor from being affected by dampness, ensuring that the cleaned floor is dry and improving the overall cleaning effect.
[0054] Reference Figure 2 , Figure 7 and Figure 8 The secondary cleaning mechanism 7 includes a square box 71. Fixed frames 72 are fixedly connected to the left and right sides of the interior of the square box 71. Long openings 73 are provided on the front and rear sides of the interior of each fixed frame 72. Square rods 74 are slidably connected inside the long openings 73. Rotating columns 75 are fixedly connected to the outside of the two square rods 74. Rollers 76 are rotatably connected to the outside of the rotating columns 75. The rollers 76 roll on the ground, performing a secondary cleaning of the ground after steam cleaning and brush 4 sweeping, further removing residual fine dust and debris, improving the cleaning effect. Support columns 77 are fixedly connected to the left and right sides of the interior of the square box 71. The support columns 77 are fixed to the left and right sides of the interior of the square box 71, providing sliding space for sliding blocks 78, supporting and guiding the movement of the rotating columns 75. The internal sliding space of the support columns 77... A sliding block 78 is connected, and a sliding rod 79 is fixedly connected to the top of the sliding block 78. The sliding rod 79 connects the sliding block 78 and the rotating column 75, transmitting the movement of the rotating column 75 to the sliding block 78. At the same time, under the action of the second spring 710, the rotating column 75 is assisted in adaptive adjustment. The left and right sides of the inside of the square box 71 are fixedly connected to the second spring 710. The top of the sliding block 78 is fixedly connected to the bottom of the sliding rod 79. The tops of the two second springs 710 are fixedly connected to the bottom left and right sides of the rotating column 75. The second spring 710 is connected between the bottom left and right sides of the rotating column 75 and the top of the sliding block 78. When the roller 76 encounters an uneven ground, the second spring 710 is compressed or extended, providing buffer and adaptive adjustment elasticity for the rotating column 75, ensuring that the roller 76 always has good contact with the ground and improving the secondary cleaning effect.
[0055] Specifically, it achieves deep cleaning and fine treatment of the already cleaned floor. Inside the square box 71, the elongated opening 73 on the fixing frame 72 provides a sliding track for the square rod 74. The square rod 74 drives the rotating column 75 and the externally connected roller 76 to roll on the floor, further removing the fine stains remaining after steam cleaning and brush 4 sweeping, improving the cleaning effect. The support column 77 provides sliding space for the sliding block 78, supporting and guiding the movement of the rotating column 75. The sliding rod 79 transmits the displacement of the rotating column 75, while the second spring 710 provides buffering and adaptive elasticity for the rotating column 75 by compression or extension when the roller 76 encounters uneven ground, ensuring that the roller 76 always keeps in contact with the ground, efficiently completing the secondary cleaning and making the floor cleaner more thorough.
[0056] Working principle: When the motor 21 in the walking mechanism 2 starts, the drive end drives the gear 22 to rotate. Since the gear 22 meshes with the gears 24 and 25, the gear 24 is mounted on the rotating rod 23, and the gear 25 is mounted on the rotating rod 26. The rotating rod 26 is externally connected to the wheel 27. Therefore, the rotation of the gear 22 will drive the gears 24 and 25 to rotate synchronously, thereby causing the wheel 27 to rotate, realizing the movement of the cleaning equipment. The caster wheel 28 assists the equipment in flexibly turning.
[0057] When motor 2 31 starts, the rotating column 32 at its drive end rotates, driving the externally detachable sleeve 33 and side brush 34 to rotate at high speed to clean the edge area of the ground. When it is necessary to remove the side brush 34, press the pressing rod 39. The pressing rod 39 pushes the pressing plate 310 to squeeze the rotating plate 37. The rotating plate 37 rotates around the rotating shaft 36 and compresses the spring 1 38, so that the rotating plate 37 is disengaged from the sleeve 33. Then the sleeve 33 and side brush 34 can be removed from the rotating column 32.
[0058] The water storage chamber 51 stores clean water. After the water pump 53 is started, the water in the water storage chamber 51 is transported to the fixed plate 54 through the pipe. The water is converted into steam under the action of the heating element and sprayed out through the steam nozzle 55 to clean the ground with steam, soften stubborn stains and improve the cleaning effect.
[0059] The fan 62 of the drying mechanism 6 starts and blows air toward the heating rod 63. The heated air is blown out from the fixed box 61 to dry the steam-cleaned ground and prevent water stains from remaining on the ground.
[0060] When the cleaning equipment moves, the rollers 76 of the secondary cleaning mechanism 7 roll on the ground, and the square rod 74 slides within the elongated opening 73. The height can be adaptively adjusted according to the ground conditions. If the ground is uneven, the rollers 76 drive the rotating column 75 to move. The rotating column 75 drives the sliding rod 79 to move inside the support column 77. The rotating column 75 compresses the spring 710, realizing the adaptive adjustment of the rollers 76, thereby improving the effect of secondary cleaning, effectively removing dust, debris and stains hidden inside, and ensuring deep cleaning.
[0061] The control module 11 receives the signal from the anti-collision sensor 10. When an obstacle is detected in front, it controls the walking mechanism 2 to adjust the direction of travel to avoid collision.
