Description

A handheld floor cleaning device and its base Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, specifically relating to a handheld floor cleaning device and its base. Background Technology

[0002] A floor scrubber is a device used for cleaning floors. It completes cleaning tasks mechanically and is widely used in public places and home environments. Floor scrubbers can quickly clean large areas of flooring, improving work efficiency and reducing the workload of cleaning personnel. Floor scrubbers are divided into suction-type floor scrubbers and non-suction-type floor scrubbers. Most existing non-suction-type floor scrubbers use a roller brush to sweep up debris. A scraper is installed near the roller brush. The debris swept up by the roller brush is caught by the scraper and swept into a collection tank. However, on uneven floors, the scraper cannot keep close to the ground, and the debris swept up by the roller brush cannot be lifted by the scraper, resulting in poor cleaning effect.

[0003] Summary of the Invention

[0040] Example 1:

[0041] As shown in Figures 1-14, the present invention provides a handheld floor cleaning device, including a mop mechanism 1, which is equipped with a handheld handle 2. The mop mechanism 1 includes a housing 3, a roller brush 4, a sludge collection tank 5, and a scraper blade 6. The sludge collection tank 5 is fixedly installed in the housing 3. The housing 3 is driven and connected to the roller brush 4 via a drive mechanism 7. An elastic cover 8 is fixedly installed in the housing 3, and a roller 9 is movably connected to the elastic cover 8. An elastic sheet 10 is fixedly installed in the elastic cover 8. A liquid tank 11 is fixedly installed in the handheld handle 2. The sludge collection tank 5 includes a filter tank 12 and a wastewater tank 13. A drain valve 14 is fixedly installed in the wastewater tank 13. The drain valve 14 includes a fixed base 15 and a valve stem 16. A rubber valve 17 is fixedly installed at the lower end of the valve stem 16, and a first spring 18 is fixedly installed at the other end of the valve stem 16. A secondary housing 19 is fixedly installed in the housing 3, and a side scraper 20 extends from the secondary housing 19. The sub-shell 19 is fixedly mounted with an easy-to-remove component 21, which is movably connected to one end of the roller brush 4 via a short shaft 22. The shell 3 is fixedly mounted with a pressing component 23, which includes a second spring 24 and a top block 25, and the top block 25 elastically presses against the sludge collection tank 5. The elastic cover 8 is elastically connected to the shell 3 via an elastic component 26, which includes a push block 27 and a third spring 28. The elastic cover 8 is provided with a drain hole 29. A stainless steel plate 30 is fixedly mounted on the shell 3 and located on one side of the roller brush 4. A temperature sensor 31 is fixedly mounted on the stainless steel plate 30, and a magnetic metal cylinder 32 is fixedly mounted on the roller brush 4. A rear wheel 33 is movably mounted on the shell 3. The drive mechanism 7 is driven and connected to the rear wheel 33 via a transmission mechanism 34, which includes a belt 35 and a gear set 36. The drive mechanism 7 is driven and connected to the gear set 36 via the belt 35. The sludge collection box 5 is equipped with a top cover 37, and a spray device 38 is fixedly installed on the top cover 37. The spray device 38 includes a cover plate 39 and a water spray body 40. The water spray body 40 is provided with a nozzle 41 and a guide channel 42. The guide channel 42 is connected to the nozzle 41. The nozzle 41 is provided with a first inclined surface 43 and a second inclined surface 44.

[0042] [Corrected according to Rule 91 12.03.2025] A base includes a base body 45, a bottom shell 46 fixedly installed on the base body 45, an induction coil 47 fixedly installed on the bottom shell 46, a drain port 48 provided on the base body 45, a charging head 49 fixedly installed on the base body 45, the charging head 49 including a spring pin 50 and a soft rubber protective sleeve 51, and a foot post 53 fixedly installed on the base body 45 through a snap-fit ​​structure 52.

[0043] Through the above technical solution, the present invention drives the roller brush 4 to rotate via the drive mechanism 7. The roller brush 4 contacts the roller 9 and drives the roller 9 to rotate. The roller brush 4 and the roller 9 cooperate to pick up the garbage. The scraper blade 6 is installed inside the mopping mechanism 1. During the cleaning process, the roller brush 4 sweeps up the garbage and sewage on the ground and, together with the roller 9, clamps and rolls the garbage into the collection tank 5. The scraper blade 6 is located at the opening of the collection tank 5. As the roller brush 4 rotates, the scraper blade 6 scrapes the garbage and sewage on the surface of the roller brush 4 into the collection tank 5, completing the cleaning process. During this process, the scraper blade 6 does not contact the ground. The roller brush 4 sweeps the ground and, together with the roller 9, clamps and rolls away the garbage on the ground, improving the cleaning effect on uneven ground and improving the cleaning effect of the floor scrubber.

[0044] Example 2:

[0045] As shown in Figures 1-14, the mop mechanism 1 is the core part of this invention, a mechanism used for cleaning the floor. The mop mechanism 1 consists of a housing 3, a roller brush 4, a sludge collection box 5, and a scraper blade 6. The housing 3 is the main basic support structure of the mop mechanism 1. The housing 3 has a complex structure. To facilitate processing and assembly of parts, the housing 3 is composed of multiple structures, including an upper shell, a middle shell, a lower shell, a sub-shell 19, and support ribs. These structures are combined into the housing 3 by bolt fixing, welding fixing, snap-fit ​​fixing, etc. The roller brush 4 is the core structure used for sweeping the floor. The roller brush 4 is driven to rotate by a drive device. The surface of the roller brush 4 is provided with bristles. When the roller brush 4 rotates, it sweeps up the garbage. Brush 4 is also absorbent, capable of drying the ground. The collection bin 5 is for collecting garbage. The scraper blade 6 is used to scrape away the garbage and wastewater swept up by the roller brush 4. The scraped garbage and wastewater fall into the collection bin 5. The scraper blade 6 can be made of soft or hard material. The collection bin 5 is fixedly installed on the housing 3 via a snap-fit ​​structure. When the collection bin 5 is full of garbage and wastewater, it can be removed for cleaning by unscrewing the snap-fit ​​structure. The housing 3 is connected to the roller brush 4 via a drive mechanism 7. The drive mechanism 7 is installed inside the housing 3 and consists of a drive motor, a speed-regulating gearbox, a connecting rod structure, and a belt 35, ensuring stable torque output. The drive mechanism 7 drives the roller brush 4 to rotate, enabling it to sweep the floor. The drive mechanism 7 connects to the roller brush 4 via a snap-fit ​​structure, facilitating roller replacement and disassembly when the roller brush 4 is damaged or needs cleaning. The housing 3 is fixedly equipped with an elastic cover 8, which prevents debris or wastewater from splashing when the roller brush 4 rotates. The elastic cover 8 has elastic deformation properties, which, in conjunction with the roller rod 9, improves the debris-sweeping effect. The roller rod 9 is movably connected to the end of the elastic cover 8, and it fits snugly against the roller brush 4. The roller brush 4 drives the roller rod 9 to rotate. When sweeping the floor, the roller brush 4 sweeps up debris, and the rotation of the roller brush 4 and roller rod 9 helps to clamp the debris. When encountering larger pieces of debris, the elastic cover 8 allows the roller 9 to be expanded. The roller brush 4 and roller 9 rotate in coordination to clamp the large debris, improving the floor cleaning effect. The elastic cover 8 is fixedly equipped with an elastic plate 10. After clamping the debris in conjunction with the roller brush 4 and roller 9, the clamped debris is sent into the mop mechanism 1 and scraped into the collection tank 5 by the scraper blade 6. During this process, the clamped debris first passes through the elastic plate 10, which presses the debris against the surface of the roller brush 4, ensuring the debris is gripped by the roller brush 4 and sent into the collection tank 5. When encountering large pieces of debris, the elastic plate 10 is expanded by the debris, allowing large pieces to pass through. The handheld handle 2 is fixedly equipped with a liquid tank 11, which holds water and cleaning solution. During floor cleaning, it automatically provides water and cleaning solution, improving the cleaning effect.

[0046] The structural design of the sludge collection tank 5 in this invention plays a crucial role in enhancing user experience and ease of use. The sludge collection tank 5 comprises two main parts: a filter tank 12 and a wastewater tank 13, which filters waste and wastewater generated during the cleaning process. The filter tank 12, located above the wastewater tank 13, is primarily responsible for filtering wastewater, separating solid waste from sewage. The filter tank 12 separates larger particles of waste and solid matter generated during the cleaning process, preventing these substances from entering the wastewater tank 13. Wastewater can be directly discharged into the toilet drain 48. The filtered wastewater prevents larger particles of waste and solid matter from clogging the sewer drain. When the roller brush 4 and scraper 6 scrape waste and wastewater into the sludge collection tank 5, the waste and wastewater first enter the filter tank 12. The filter material inside the filter tank 12 effectively intercepts and retains larger waste particles. The filtered wastewater then flows downwards to the wastewater tank 13 under gravity. The wastewater tank 13, located below the filter tank 12, is responsible for receiving the wastewater flowing down from the filter tank 12. A drain valve 14 is provided at the bottom of the sewage tank 13. The drain valve 14 is used to control the discharge of sewage from the sewage tank 13. Users can discharge the sewage in the sewage tank 13 to an external container or drainage system through the drain valve 14. The drain valve 14 includes a fixed seat 15 and a valve stem 16. A rubber valve 17 is fixedly installed at the lower end of the valve stem 16, and a first spring 18 is fixedly installed at the other end of the valve stem 16. The fixed seat 15 has a sliding hole, and the valve stem 16 is installed in the sliding hole and can move back and forth. A rubber valve 17 for sealing the valve port is installed at the bottom end of the valve stem 16, and a first spring 18 is installed at the top end of the valve stem 16. The first spring 18 elastically presses against the valve stem. On 16, the glue valve 17 seals the valve port to prevent leakage. The drain valve 14 cooperates with the drain port 48 of the base body 45. A top column is provided at the drain port 48 to open the drain valve 14. When the user puts the floor scrubber into the base body 45, the top column directly opens the drain port 48. Specifically, the top column presses the glue valve 17, causing the valve stem 16 to slide upward. The first spring 18 is compressed, causing the glue valve 17 to open the valve port and discharge the sewage in the sewage tank 13. After the floor scrubber is removed from the base body 45, the compressed first spring 18 presses the valve stem 16, causing the glue valve 17 to seal the valve port, easily completing the sewage discharge operation and improving the user experience.

[0047] Example 3:

[0048] As shown in Figures 1-14, a secondary shell 19 is fixedly installed on the housing 3 of the present invention, and a side scraper 20 extends from the secondary shell 19. The secondary shell 19 serves as an additional part of the housing 3, further enhancing the functionality of the device. The side scraper 20 is part of the secondary shell 19, and its main function is to guide the debris and sewage on the side of the roller brush 4 toward the center of the roller brush 4, making it easier for the scraper blade 6 to more effectively scrape and sweep this debris and sewage into the collection tank 5. The side scraper 20 extending from the secondary shell 19 has an angle with the roller brush 4, which ranges from 30° to 70°, to ensure that the side scraper 20 can effectively guide the debris and sewage. The side scraper 20 is designed to handle debris and sewage that cannot be scraped and grabbed by the scraper blade 6 at the edge of the roller brush 4. The angle of the side scraper 20 allows it to guide the debris and sewage to the central area of ​​the roller brush 4 during its rotation, thereby preventing debris and sewage from accumulating at the edge of the roller brush 4 or dripping onto the ground. In actual operation, due to structural limitations, to maximize the cleaning area of ​​the floor scrubber in one pass, the length of the roller brush 4 is greater than that of the scraper blade 6. This causes the scraper blade 6 to be unable to reach the edge area of ​​the roller brush 4. The side scraper 20 guides the debris and wastewater from the side of the roller brush 4 towards the center. Due to the rotation direction and speed of the roller brush 4, the side scraper 20 contacts the roller brush 4 and guides the debris and wastewater from the side of the roller brush 4 to the center. Once the debris and wastewater are guided to the center of the roller brush 4, the scraper blade 6 can clean more effectively. The scraper blade 6 is located in front of or to the side of the roller brush 4, scraping away debris and wastewater from the surface of the roller brush 4 and guiding it into the collection tank 5.

[0049] The sub-shell 19 of this invention is fixedly equipped with an easy-to-remove component 21. The easy-to-remove component 21 is movably connected to one end of the roller brush 4 via a short shaft 22 to optimize the maintenance and replacement process of the roller brush 4. The easy-to-remove component 21 is an important additional part, movably connected to one end of the roller brush 4 via the short shaft 22, and works with the drive mechanism 7 to movably fix the roller brush 4. The main function of the easy-to-remove component 21 is to simplify the disassembly and replacement operation of the roller brush 4, allowing users to easily and quickly complete the cleaning or replacement of the roller brush 4. The easy-to-remove component 21 is connected to one end of the roller brush 4 via the short shaft 22, which, as a key structural component of the easy-to-remove component 21, ensures a stable connection between the roller brush 4 and the drive mechanism 7. In actual use of the equipment, the roller brush 4 needs to be disassembled for cleaning and replacement. During use, the roller brush 4 will accumulate a certain amount of dirt and debris, so regular cleaning is necessary. After prolonged use, the roller brush 4 may experience wear or damage, at which point it needs to be replaced with a new roller brush 4 to maintain the cleaning effect of the equipment. The easy-removable component 21 greatly simplifies this process. Users can quickly remove the roller brush 4 by simply detaching the component 21, avoiding cumbersome steps. Specifically, when users need to clean or replace the roller brush 4, they can follow these steps: First, by operating the locking device or disassembly mechanism on the easy-removable component 21, the connection between the short shaft 22 and the roller brush 4 is released. At this point, the easy-removable component 21 can be easily removed, allowing the roller brush 4 to detach from the drive mechanism 7. Then, the user can clean the roller brush 4, ensuring that its surface is free of residual dirt. If the roller brush 4 needs to be replaced, the user can remove the old roller brush 4, install the new roller brush 4, and reconnect the easy-removable component 21 to the roller brush 4 end. During reconnection, the easy-removable component 21, through the cooperation between the short shaft 22 and the roller brush 4 end, ensures that the roller brush 4 is firmly fixed, thereby restoring the normal function of the equipment. This design of the easy-removable component 21 not only improves the maintenance efficiency of the equipment but also reduces the difficulty of operation for users. In previous equipment designs, disassembling and replacing the roller brush 4 could involve complex tools and procedures. However, the easy-to-remove component 21 makes these operations more intuitive and convenient. Users can quickly complete the cleaning and replacement of the roller brush 4, maintaining the equipment in optimal working condition and ensuring that the cleaning effect is not affected.

[0050] Example 4:

[0051] As shown in Figures 1-14, the top-pressing assembly 23 fixedly installed on the housing 3 of the present invention improves the cleaning performance of the equipment. The top-pressing assembly 23 includes a second spring 24 and a top block 25. The purpose of this structure is to ensure that the scraper blade 6 on the sludge collection tank 5 is always kept in optimal working condition, thereby improving the cleaning effect. The top-pressing assembly 23 is fixed on the housing 3 and achieves the top-pressing function on the sludge collection tank 5 through the second spring 24 and the top block 25. The second spring 24 is a component with elastic properties. The elastic pressure presses the scraper blade 6 on the sludge collection tank 5 towards the roller brush 4. During the cleaning process, the rotation and friction of the roller brush 4 will cause the scraper blade 6 to gradually wear. If the scraper blade 6 cannot stick tightly to the roller brush 4, the cleaning effect of garbage and sewage will be affected. In the actual environment in which the equipment is used, the roller brush 4 will continuously rotate and sweep up garbage on the ground, while pushing garbage and sewage to the scraper blade 6. The function of the scraper blade 6 is to scrape off the garbage and sewage swept up by the roller brush 4 and guide this garbage and sewage into the sludge collection tank 5. However, with continued use, the scraper blade 6 may experience reduced contact with the roller brush 4 due to wear, thus affecting the cleaning effect. To address this issue, the top-pressing assembly 23 continuously applies pressure to the top block 25 via the elastic force of the second spring 24, keeping the scraper blade 6 on the surface of the roller brush 4 and ensuring its effective removal of debris from the roller brush 4. The top block 25 transmits the elastic force generated by the second spring 24 to the scraper blade 6. The top block 25 is pressed tightly against one side of the scraper blade 6, while the second spring 24 applies pressure to the top block 25. This configuration ensures continuous contact between the scraper blade 6 and the roller brush 4. During cleaning, the pressure of the top block 25 compensates for the wear of the scraper blade 6, keeping it in close contact with the roller brush 4 at all times. Thus, even after prolonged use, the scraper blade 6 can still effectively scrape away debris and wastewater from the roller brush 4, maintaining a high level of cleaning performance. The top block 25 elastically presses against the sludge collection tank 5, ensuring that the scraper blade 6 remains in close contact with the roller brush 4 at all times. This adaptive pressure adjustment mechanism effectively prevents the scraper blades from losing their grip due to wear, thereby improving the cleaning ability of the equipment.

[0052] Example 5:

[0053] As shown in Figures 1-14, the elastic cover 8 of the present invention is connected to the housing 3 via the elastic component 26, improving the cleaning performance of the present invention, especially for sweeping large-volume debris. The elastic cover 8 is elastically connected to the housing 3 via the elastic component 26, ensuring the adaptability and operational flexibility of the equipment under various ground conditions. The elastic component 26 consists of a push block 27 and a third spring 28. The push block 27 is fixed to the elastic cover 8, and the third spring 28 is connected between the push block 27 and the housing 3. This structural arrangement allows the elastic cover 8 to elastically deform during use. When the roller brush 4 and roller 9 encounter large-volume debris during cleaning, the elastic component 26 enables the elastic cover 8 to effectively expand and contract elastically. The roller 9 is fixed to the elastic cover 8 and works in conjunction with the roller brush 4. When the roller brush 4 rotates, it can sweep up debris on the ground, while the roller 9 further clamps the debris, especially when the debris is large. The elastic properties of the elastic component 26 allow the elastic cover 8 to open slightly when encountering large debris, thereby increasing the gap between the roller 9 and the roller brush 4. In this way, large debris can be smoothly picked up by the roller brush 4 and the roller 9 and carried into the collection tank 5. When encountering larger debris during the cleaning process, the elastic force provided by the third spring 28 allows the elastic cover 8 to deform elastically, and the action of the push block 27 and the spring causes the elastic cover 8 to open slightly. This elastic opening mechanism allows the gap between the roller 9 and the roller brush 4 to increase, so that larger debris can also be picked up smoothly.

[0054] The elastic cover 8 of the present invention is provided with a drain hole 29. When the roller brush 4 is being cleaned, water will splash onto the elastic cover 8. The interior of the elastic cover 8 is a hollow structure, and water will accumulate inside the elastic cover 8. The water is drained through the drain hole 29 to prevent water from accumulating inside the elastic cover 8.

[0055] Example 6:

[0056] As shown in Figures 1-14, the drying function of the roller brush 4 of this invention is achieved through the cooperation of a stainless steel plate 30 and a magnetic metal cylinder 32 with an electromagnetic coil in the base body 45. A stainless steel plate 30 is fixedly installed on the housing 3, located on one side of the roller brush 4. The stainless steel plate 30 is in an arc shape and does not directly contact the roller brush 4, acting like a cover. The magnetic metal cylinder 32 is fixedly installed on the roller brush 4, and the electromagnetic coil is located in the base body 45. This configuration utilizes the principle of electromagnetic induction heating to dry the roller brush 4, thereby improving the cleaning efficiency and ease of use of the equipment. The magnetic metal cylinder 32 is made of stainless steel. When the device is working, the electromagnetic coil in the base body 45 generates a high-frequency magnetic field, causing eddy currents inside both the stainless steel plate 30 and the magnetic metal cylinder 32. Due to the resistance inside the stainless steel plate 30 and the magnetic metal cylinder 32, heat is generated. The stainless steel plate 30, after being heated, dries the roller brush 4 from the outside, while the magnetic metal cylinder 32, after being heated, heats the roller brush 4 from the inside, causing the roller brush 4 to heat up and evaporate moisture. This internal and external heating process increases the drying speed of the roller brush 4. During the heating process, the roller brush 4 continues to rotate, ensuring even heating of the magnetic metal cylinder 32 and uniform drying of the brush bristles on the surface of the roller brush 4 by the stainless steel plate 30. During cleaning, the roller brush 4 comes into contact with various liquids and dirt, which may remain on the bristles. If the bristles cannot dry quickly after cleaning, it may lead to bacterial growth or unpleasant odors. The heating function of the magnetic metal cylinder 32 effectively evaporates the moisture on the surface of the roller brush 4, keeping the bristles dry and hygienic. It can not only improve the cleaning effect of the equipment, but also extend the service life of the roller brush 4.

[0057] The housing 3 of this invention is movably fitted with a rear wheel 33, and the drive mechanism 7 drives the rear wheel 33 via a transmission mechanism 34. During the cleaning process, the rotation of the roller brush 4 generates a certain driving force, which tends to cause the mop mechanism 1 to move forward. To counteract this tendency and improve the operational stability and comfort of the device, the rotation direction of the rear wheel 33 is set to be opposite to that of the roller brush 4. With this configuration, the rear wheel 33 can effectively counteract the pushing force generated by the rotation of the roller brush 4, thereby allowing the mop mechanism 1 to maintain a more stable movement during the cleaning process. The drive mechanism 7 drives the movement of the rear wheel 33 via the transmission mechanism 34, and this connection method ensures that the rotation of the rear wheel 33 is in a different direction from the rotation of the roller brush 4. Specifically, when the roller brush 4 rotates, it pushes the mop mechanism 1 forward, while the reverse rotation of the rear wheel 33 produces an effect opposite to the pushing force of the roller brush 4. The rotation direction of the rear wheel 33 is opposite to the rotation direction of the roller brush 4, so that the pushing force generated by the roller brush 4 is effectively counteracted, thereby preventing the mop mechanism 1 from moving forward excessively. The transmission mechanism 34 includes a belt 35 and a gear set 36. The drive mechanism 7 is connected to the gear set 36 via the belt 35. The gear set 36 is connected to the rear wheel 33 via a connecting rod, gears, and a transmission belt, causing the rear wheel 33 to rotate in the opposite direction to the roller brush 4. This configuration makes the device more stable during use and avoids operational difficulties caused by excessive movement due to the rotation of the roller brush 4. In actual use, this design significantly improves the user experience. Users can feel the stability of the device during cleaning without needing to control the movement direction of the mop mechanism 1 excessively. Because the reverse rotation of the rear wheel 33 counteracts the pushing force of the roller brush 4, users can maintain better control when operating the device.

[0058] Example 7:

[0059] As shown in Figures 1-14, the sludge collection tank of the present invention is equipped with a top cover, and a spraying device is fixedly installed on the top cover. The top cover is fastened to the opening of the sludge collection tank by a snap-fit ​​structure to seal the sludge collection tank. A spraying device is installed on the top cover of the sludge collection tank. The main function of the spraying device is to spray and clean the roller brush. The spraying device includes a cover plate and a water spray body. The water spray body is provided with nozzles and a guide channel. The guide channel is connected to the nozzles. A water inlet is provided on the cover plate. An electric pump pressurizes and pumps water or cleaning solution from the liquid tank out, which flows into the guide channel from the water inlet and then is sprayed out through the nozzles. Every two nozzles form a spray head. The water spray body is provided with a spray head, i.e., a nozzle. The nozzle is provided with a first inclined surface and a second inclined surface. The height of the second inclined surface is lower than the height of the first inclined surface. During water spraying, the nozzles on both sides of the water-pressure spray head eject atomized water. The water flow first exits along the first inclined plane, then is divided into upper and lower parts by the second inclined plane. The upper part of the water flow has a larger spray angle, allowing it to reach areas farther from the nozzles, while the lower part of the water flow, under the influence of the second inclined plane, has a smaller spray angle, allowing it to reach areas closer to the nozzles. The first and second inclined planes ensure that the nozzles spray a uniform water mist, ensuring even coverage of the roller brush and improving the cleaning effect. This liquid is then sprayed onto the roller brush through the spray pipe device, thus cleaning it. The spray device is positioned above the roller brush, allowing it to directly spray water or cleaning solution onto the brush surface. The spray device is pumped with cleaning liquid by an electric pump. The electric pump pressurizes the water or cleaning solution in the liquid tank and then delivers it to the spray pipe device. The use of the electric pump ensures that the spray device operates under high pressure, allowing the sprayed liquid to achieve the best cleaning effect. Pressurized liquid is sprayed onto the roller brush in a mist form through a spray pipe device, ensuring high efficiency in the cleaning process. During cleaning, as the roller brush rotates, the water or cleaning solution sprayed by the spray device continuously contacts the surface of the roller brush, helping to remove dirt and debris. The liquid spray not only helps clean the bristles but also washes away dirt and impurities from the bristles, thereby improving the overall cleaning effect of the equipment.

[0060] Example 8:

[0061] As shown in Figures 1-14, the base body 45 of this invention enhances the overall functionality of the handheld floor cleaning device. The base body 45 is the main supporting structure of the device, and a bottom shell 46 is fixedly mounted on it, responsible for supporting and protecting the internal electronic components, including circuit boards and induction coils 47. The induction coil 47 is fixedly mounted on the bottom shell 46. The function of the induction coil 47 is to generate a high-frequency magnetic field, heating the magnetic metal cylinder 32 and stainless steel plate 30 on the roller brush 4. Through the heating by the induction coil 47, the roller brush 4 can dry quickly after cleaning, preventing the bristles from becoming damp and breeding bacteria or producing odors. The interaction between the induction coil 47 and the magnetic metal cylinder 32 and stainless steel plate 30 realizes the heating process, allowing the moisture on the surface of the roller brush 4 to be effectively evaporated, thereby improving cleaning efficiency and maintaining the hygiene of the device. The base body 45 also has a drain port 48, which is used in conjunction with the drain valve 14 of the wastewater tank 13. A top column is installed on the drain port 48, the function of which is to open the drain valve 14 to discharge wastewater. After cleaning, the user can connect the wastewater tank 13 to the drain port 48 of the base body 45. Through the action of the top column, the wastewater in the tank 13 can be smoothly discharged, keeping the equipment clean and operating normally. The top column design ensures the convenience and efficiency of the drainage process, reducing the user's labor intensity when cleaning wastewater. A charging head 49 is fixedly installed on the base body 45. The charging head 49 connects to the electrical terminals on the rotary joint of the handheld handle 2 to charge the battery inside the handheld handle 2. When the handheld device is placed on the base body 45, the charging head 49 connects to the electrical terminals, and the battery begins to charge. In this way, the device's battery can be charged during breaks in use, ensuring that the device provides sufficient power for the next use. This design not only improves the ease of use of the device but also ensures continuous battery performance, enabling the handheld floor cleaning device to maintain efficient operation during prolonged use.

[0062] Example 9:

[0063] As shown in Figures 1-14, the handheld handle 2 of this invention is movably connected to the mop mechanism 1 via a rotary joint. The rotary joint has a two-axis movable function, allowing the mop mechanism 1 to rotate around the handheld handle 2, and the handheld handle 2 to swing vertically. This structural design aims to improve the flexibility of the floor scrubber and meet the requirements of different cleaning environments and operational needs. The rotary joint's function allows the mop mechanism 1 to rotate at multiple angles around the handheld handle 2, enabling users to easily adjust the working angle of the mop mechanism 1 during cleaning. The rotation function of the mop mechanism 1 is particularly suitable for cleaning corners, edges, and other hard-to-reach areas, allowing users to achieve more comprehensive cleaning coverage by rotating the mop mechanism 1. The rotary joint design allows the mop mechanism 1 to flexibly adjust its working direction, satisfying horizontal, vertical, and diagonal cleaning needs through rotation. In addition to the rotation function, the rotary joint also has the ability to swing vertically, allowing the handheld handle 2 to swing vertically. This swinging function improves the operating comfort and flexibility of the equipment. In practical use, when users need to clean the floor, they can flexibly adjust the working posture of the mop mechanism 1 through the two-axis movable function of the rotary joint. For example, when cleaning corners of the floor, users can rotate the mop mechanism 1 to adjust it to a suitable angle so that the mop mechanism 1 can fully contact the corner area.

[0064] Electrical terminals are fixedly installed on the rotary joint of this invention, and a battery is installed inside the handheld handle 2. The function of the electrical terminals is to connect with the charging head 49 of the base body 45, thereby charging the battery. The battery installed inside the handheld handle 2 provides the power required by the device, enabling the handheld floor cleaning device to operate independently. The battery capacity and power determine the device's usage time and cleaning range. During device use, when the battery power is low, the user can place the floor scrubber on the base body 45, and the electrical terminals will automatically connect with the charging head 49 of the base body 45. At this time, a power transmission channel is formed between the charging head 49 and the electrical terminals, and the battery begins to charge. The charging process is automatically started through the connection of the electrical terminals, eliminating the need for manual operation of the charging device by the user, making the charging process more convenient.
