Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and specifically to a cleaning device and a cleaning system. Background Technology

[0002] Current handheld wet cleaning devices, such as floor scrubbers, can only clean hard floors using a damp cloth roller brush, and cannot clean carpets or other special floor materials. To solve this problem, traditional floor scrubbers can be designed with switchable dry and wet roller brushes, and the piping system can be improved to give the scrubber a vacuuming function, thus transforming it into a dual-purpose wet and dry cleaning device. However, since wet and dry cleaning target different floor materials, the required roller brush speeds also differ. Compared to the scrubbing mode (wet cleaning), where the roller brush operates at a lower speed, the vacuuming mode (dry cleaning) requires the motor to operate at high speed and high load to drive the roller brush to rotate at high speed to meet the vacuuming requirements. However, this creates a new technical problem: the motor design of traditional floor scrubbers cannot withstand excessively high operating temperatures, leading to overheating of the motor casing. Furthermore, the scrubbing mode is usually activated immediately after vacuuming, requiring the user to manually remove and replace the wet roller brush to ensure cleaning effectiveness. However, when users remove the wet roller brush for replacement, the motor assembly built into the roller brush cavity is directly exposed to the user before it has cooled down. Therefore, there is a risk of accidentally touching the motor assembly housing and getting hot, resulting in a poor user experience and safety issues. Utility Model Content

[0041] Please see Figures 1 to 3 One embodiment of this application provides a cleaning device 200, which includes a main body 201 and a floor brush device 100, which are connected by a recycling channel 41. The floor brush device 100 includes a roller brush 10, a drive assembly 20, and a spray assembly 30. The drive assembly 20 includes a drive member 21 and a housing 22. The housing 22 covers the drive member 21, and the roller brush 10 is covered by the housing 22. The drive member 21 is connected to and drives the roller brush 10 to rotate. The drive member 21 is driveably connected to the roller brush 10 to operate at least at a first speed and a second speed, wherein the first speed is greater than the second speed. At least a portion of the spray assembly 30 is disposed within the floor brush device 100. The spray assembly 30 includes an air intake channel 33 and a nozzle (not shown in the figure). The nozzle is located within the recovery channel 41. The air intake port 334 of the air intake channel 33 is disposed within the housing 22. The spray assembly 30 is used to generate airflow disturbance between the roller brush 10 and the housing 22 during the rolling process driven by the drive assembly 20. It should be noted that the roller brush 10 is not limited to operating at the first speed and the second speed. It can be operated at other different speeds by the drive member 21 or other components according to actual design requirements.

[0042] In this embodiment, the cleaning device 200 may include a vacuuming mode and a floor washing mode. In the vacuuming mode, the drive unit 21 drives the roller brush 10 to rotate at a first speed. When the drive unit 21 is in the floor washing mode, it drives the roller brush 10 to run at a second speed. The first speed is greater than the second speed, and the water content of the roller brush 10 in the vacuuming mode is less than the water content of the roller brush 10 in the floor washing mode.

[0043] Understandably, the rotation speed of the drive component 21 of the floor brush device differs between vacuuming and washing modes, resulting in different cleaning effects from the cleaning device 200. The floor brush device can switch between a first and a second rotation speed (i.e., vacuuming and washing modes). When the drive component 21 rotates at the first rotation speed, the high speed causes the temperature of the drive component 21 to rise. Simultaneously, the spray assembly 30 needs to humidify the dust sucked into the recovery channel 41 during vacuuming mode to improve the vacuuming efficiency of the cleaning device 200. In other words, adding a vacuuming mode increases the need for dust humidification and the high-speed rotation of the drive component 21. The high-speed rotation of the drive component 21 causes the housing 22 to overheat. Therefore, users need to manually remove and replace the wet roller brush when the cleaning device 200 is in different modes to ensure cleaning effectiveness. During this process, the spray assembly 30 can generate airflow disturbance between the roller brush 10 and the housing 22 through the air intake channel 33 to cool the housing 22, thus preventing the risk of users accidentally touching the housing 22 and getting burned.

[0044] It should be noted that, in this embodiment, by designing the spray assembly 30 and rationally setting the positions of the air intake channel 33 and nozzles, the need for humidifying the dust in the recovery channel 41 and cooling the drive assembly 20 generated after the cleaning device 200 adds a dust suction mode can be simultaneously addressed. In this embodiment, the spray assembly 30 can agitate the air in the space between the roller brush 10 and the housing 22, thereby removing heat from the drive assembly 20. Thus, on the one hand, the spray assembly 30 can humidify the dust entering the recovery channel 41 through the nozzles, improving the working efficiency of the cleaning device 200; on the other hand, the spray assembly 30 can generate airflow agitation between the roller brush 10 and the housing 22 through the air intake channel 33 to remove heat from the vicinity of the housing 22, thereby cooling the housing 22 and preventing the housing 22 from overheating and causing burns to the user's hands.

[0045] In this embodiment, the spray assembly 30 includes an air pump 31 and an air inlet pipe 32, with the air pump 31 connected to the air inlet channel 33 via the air inlet pipe 32.

[0046] In this embodiment, the floor brush device 100 can switch between a vacuuming mode and a floor washing mode (i.e., dry cleaning and wet cleaning). In vacuuming mode, the temperature of the drive component 21 increases, and the spray assembly 30 can agitate the air in the space between the roller brush 10 and the housing 22, thereby removing the heat from the drive component 20. In this way, on the one hand, the drive component 20 can be cooled down to improve its working efficiency, and on the other hand, when the user needs to replace the roller brush 10, the housing 22 will not overheat and cause accidental burns.

[0047] It should be noted that because wet cleaning and dry cleaning target different surfaces, the required rotational speed of the roller brush 10 also differs (i.e., the first rotational speed is greater than the second). In vacuuming mode, the drive unit 21 drives the roller brush 10 to rotate at the first rotational speed, which is relatively high and causes the temperature of the drive unit 21 and the housing 22 to rise. After vacuuming, users often switch the floor brush device 100 to floor washing mode. At this time, the user needs to manually replace the roller brush 10, exposing the housing 22 to the outside. This poses a risk of burns to the user's hands, resulting in a poor user experience and safety concerns.

[0048] The floor brush device 100 of this application embodiment includes an air pump 31 and an air intake channel 33. The air intake channel 33 provides air to the air pump 31 while generating airflow disturbance between the roller brush 10 and the housing 22. In other words, the floor brush device 100 of this application embodiment simultaneously solves the problems of air intake of the air pump 31 and heat dissipation of the housing 22.

[0049] In this embodiment, the spray component 30 can be the air pump 31 already present in the floor brush device 100. The spray component 30 generates airflow disturbance between the roller brush 10 and the housing 22 through the air intake channel 33. Thus, without adding any additional structural components, cooling of the drive component 20 can be achieved simply by designing the position of the air intake channel 33. In this embodiment, the air pump 31 itself has the function of atomizing the dust after suction. This embodiment redesigns the air intake channel 33 of the air pump 31, so that while the air intake channel 33 draws in air to atomize it, it also draws in hot air to cool the housing 22, thereby achieving reuse of the spray component 30 and making the floor brush device 100 perform better and more comprehensively.

[0050] In this embodiment, the air inlet 334 is disposed on the outer surface of the housing 22 facing the roller brush 10.

[0051] It is understood that, in the embodiments of the application, the spray assembly 30 can generate airflow disturbance between the roller brush 10 and the housing 22, and its specific form is not limited to meet different needs. For example, the spray assembly 30 can be an air pump 31, and the air inlet 334 of the air pump 31 can be disposed between the roller brush 10 and the housing 22, thereby blowing air to dissipate heat in the space between the roller brush 10 and the housing 22 during the operation of the air pump 31. In this document, the air inlet 334 is used to describe the heat dissipation of the space between the roller brush 10 and the housing 22, and the specific details will not be repeated.

[0052] In this embodiment, the spray assembly 30 and the floor brush device 100 are in different modes. That is, the spray assembly 30 can be activated when the floor brush device 100 is in vacuuming mode or floor washing mode to dissipate heat from the space between the roller brush 10 and the housing 22.

[0053] In this embodiment, the spray assembly 30 can humidify the dust collected in the dust collection chamber and also dissipate heat from the space between the roller brush 10 and the housing 22. By reusing the spray assembly 30, the air intake channel 33 of the spray assembly 30 is positioned between the housing 22 and the roller brush 10 to draw air from the space between the roller brush 10 and the housing 22, thereby removing heat from the drive assembly 20. When the user needs to replace the roller brush 10, there will be no problem of the housing 22 overheating and accidentally touching it, resulting in burns.

[0054] Specifically, the drive assembly 20 includes a drive member 21 and a housing 22, with the housing 22 covering the drive member 21 and the roller brush 10 covering the housing 22. The drive member 21 is a motor used to drive the roller brush 10 to rotate for cleaning the floor. The drive member 21 can rotate about a central axis within the housing 22, wherein at least a portion of the structure of the drive member 21 can extend outside the housing 22. The roller brush 10 can be connected to the portion of the drive member 21 extending outside the housing 22 via a locking structure (not shown in the figure), so that the drive member 21 can drive the roller brush 10 to rotate around the housing 22. The locking structure is detachable; when the roller brush 10 needs to be replaced, the locking structure can be opened to remove the roller brush 10 from the drive assembly 20 for replacement.

[0055] Furthermore, in this embodiment, the specific type of the roller brush 10 is not limited to meet different needs. For example, the roller brush 10 may include a rubber tube and a flocking component, which facilitates the roller brush 10 to rotate under the drive of the drive member 21 after being wetted to clean the floor.

[0056] Furthermore, please combine Figure 4The roller brush 10, which is mounted on the housing 22, has a certain gap with the housing 22. The gap between the roller brush 10 and the housing 22 is preferably about 1 mm. This can reduce unnecessary friction between the two and also provide sufficient suction space for the air intake channel 33 of the spray assembly 30, preventing the roller brush 10 from blocking the air intake port 334.

[0057] In this embodiment, when the roller brush 10 consists of a rubber tube and a flocked component, the flocked component can absorb water and moisten it to clean the ground, while the rubber tube can prevent water from entering the gap between the roller brush 10 and the housing 22, thus affecting the operation of the spray assembly 30. Of course, in some embodiments, a dedicated waterproof gasket can also be provided between the roller brush 10 and the housing 22, with a gap space between the waterproof gasket and the housing 22 for air extraction. The waterproof gasket can prevent water from the roller brush 10 or the ground from entering this gap space.

[0058] In some embodiments, the floor brush device 100 includes a vacuuming mode and a washing mode. For example, the vacuuming mode can be a vacuuming mode. When the floor brush device 100 is in vacuuming mode, the sucked-in dust will fly inside the floor brush device 100, easily causing pollution. At this time, the spray assembly 30 can suck in gas through the air intake channel 33 and pressurize it to form high-pressure gas. The high-pressure gas then atomizes and pressurizes water before spraying it out, thereby humidifying the sucked-in dust and preventing the dust inside the floor brush device 100 from flying and causing pipe blockage or other pollution.

[0059] Specifically, the floor brush device 100 may also include a water pump assembly (not shown in the figure), which, together with the spray assembly 30, can wet the sucked-in dust to prevent dust from accumulating at the filter element (not shown in the figure) before the dust pump (not shown in the figure), causing the filter element to become clogged and affecting the working efficiency of the dust pump.

[0060] Furthermore, the vacuuming mode requires the drive component 20 to rotate at a higher speed (e.g., 1200 rpm), increasing the load on the drive component 20 and generating more heat. Simultaneously, the vacuuming mode reduces the water content of the roller brush 10, weakening the heat dissipation capacity of the drive component 20, further increasing the heat generated by the drive component 20 and causing the housing 22 to overheat. At this point, if the user needs to replace the roller brush 10, they are easily burned by the housing 22. In this embodiment, the air intake channel 33 of the spray component 30 can be placed in the gap between the roller brush 10 and the housing 22. Utilizing the principle that the spray component 30 needs to draw in gas when atomizing and pressurizing water, the air intake channel 33 can draw away the hot gas between the roller brush 10 and the housing 22.

[0061] Of course, the spray assembly 30 can also operate in other modes. This embodiment does not limit the operating time of the spray assembly 30 to meet various needs. Thus, by reusing the spray assembly 30, the air intake channel 33 of the spray assembly 30 is positioned between the housing 22 and the roller brush 10 to extract air from the space between the roller brush 10 and the housing 22, thereby removing the heat generated by the drive assembly 20 and preventing overheating. In this way, if the user accidentally touches the drive assembly 20 when the roller brush 10 needs to be replaced, the lower-temperature housing 22 will not burn the user. Thus, without adding additional components, a better user experience can be provided.

[0062] Furthermore, when the floor brush device 100 is in vacuum mode, the spray component 30 atomizes and pressurizes water and sprays water mist to moisten the dust, while also cooling the inhaled hot air, which can prevent heat accumulation inside the floor brush device 100 and thus ensure the performance of the floor brush device 100.

[0063] Additionally, the floor cleaning mode can be a floor cleaning mode, which requires a lower rotation speed of the drive unit 21 and a higher water content of the roller brush 10. This application embodiment does not limit the specific mode setting of the floor brush device 100. For example, it may also have a third mode, which can be a combination of vacuuming and floor cleaning modes. Furthermore, more different power levels and modes can be set to meet various cleaning needs.

[0064] Please see Figure 5 and Figure 6 In some embodiments, the spray assembly 30 further includes an air pump 31 and an air inlet pipe 32, the air pump 31 being connected to the air inlet channel 33 via the air inlet pipe 32.

[0065] In this way, the continuous pipelines and channels can create a negative pressure inside the spray assembly 30, allowing the airflow to be smoothly transmitted to the gap between the roller brush 10 and the housing 22, drawing away the hot gas between the roller brush 10 and the housing 22, and dissipating heat for the drive assembly 20.

[0066] Specifically, the air pump 31 is connected to the air intake pipe 32 and then to the air intake channel 33. When the air pump 31 is working, it will generate a negative pressure and transfer the negative pressure to the air intake pipe 32 connected to the air pump 31, so that a negative pressure is formed in the air intake pipe 32. The negative pressure in the air intake pipe 32 is then transferred to the air intake channel 33 connected to the other end of the air intake pipe 32, so that the air intake channel 33 has a negative pressure suction force, thereby drawing in the hot gas between the roller brush 10 and the housing 22 at the other end of the air intake channel 33 to dissipate heat for the drive assembly 20.

[0067] Please see Figure 1 , Figure 5 and Figure 6In some embodiments, the air inlet 334 is disposed on the outer surface of the housing 22 facing the roller brush 10.

[0068] In this way, the position of the air inlet 334 is fixed, and the position of the air intake channel 33 is also fixed. The air inlet 334 is set on the outer surface of the housing 22 facing the roller brush 10, which can generate airflow at the gap between the housing 22 and the roller brush 10. During the process of the airflow entering the air inlet 334, the housing 22 can be cooled.

[0069] Specifically, the housing 22 can be made of a harder material that is more resistant to high temperatures and less prone to deformation (such as metal, ceramic or composite materials). This is beneficial to increasing the airtightness of the air intake channel 33 and the service life of the housing 22, and to facilitating the removal of hot gas between the roller brush 10 and the housing 22, so as to dissipate heat for the drive component 20.

[0070] Furthermore, the air inlet 334 and part of the air intake channel 33 can be set on the housing 22 at a location on the drive assembly 20 that is prone to overheating, so that the spray assembly 30 can efficiently dissipate heat from the drive assembly 20.

[0071] In the embodiments of this application, the size of the air inlet 334 is sufficient to meet the air intake volume, and no specific limitation is made here.

[0072] Please refer to the following: Figure 2 , Figure 3 and Figure 6 as well as Figure 7 In some embodiments, the floor brush device 100 further includes a floor brush body 40 and a suspension bracket 50, the floor brush body 40 being connected to the drive assembly 20 via the suspension bracket 50; the air pump 31 of the spray assembly 30 is located inside the floor brush body 40, and at least a portion of the air intake channel 33 is located inside the suspension bracket 50.

[0073] In this way, the brush body 40, the suspension bracket 50 and the drive component 20 are connected together, and the various parts of the spray component 30 are set in the three components of the brush device 100. Heat dissipation of the drive component 20 can be achieved without adding extra air channels, thus increasing the aesthetics of the brush device 100.

[0074] For example, the brush body 40 is connected to one end of the suspension bracket 50, and the other end of the suspension bracket 50 is connected to the outside of the drive assembly 20. Meanwhile, the air inlet 334 of the air intake channel 33 is located on the outer side of the housing 22 (i.e., near the suspension bracket 50). At least a portion of the air intake channel 33 leads into the housing 22, then bends and extends from the housing 22 into the suspension bracket 50, and then bends and extends again into the brush body 40, thus allowing the air inlet 334 to lead from the air intake channel 33 towards the air pump 31 located within the brush body 40. This facilitates the transfer of the negative pressure generated by the air pump 31 during operation through the air intake channel 33 to the air inlet 334, thereby drawing away the hot gas accumulated between the roller brush 10 and the housing 22 and dissipating heat from the drive assembly 20.

[0075] In addition, the roller brush 10 can move up and down vertically under the action of the suspension bracket 50 to enhance the cleaning performance of the floor brush device 100 and facilitate the floor brush device 100 to clean the gaps between floor tiles and scattered foreign objects on the ground.

[0076] Please refer to the following: Figure 5 and Figure 6 In some embodiments, the air intake passage 33 further includes a first air intake section 331, a second air intake section 332, and a third air intake section 333 connected in sequence;

[0077] The first air intake section 331 is connected to the air intake 334 and passes through the suspension bracket 50; the second air intake section 332 is installed inside the suspension bracket 50 of the floor brush device 100; the third air intake section 333 passes through the suspension bracket 50 and is connected to the air pump 31 and the second air intake section 332.

[0078] In this way, the air intake channel 33 connects the air intake port 334 and the air pump 31 together, making it convenient for the air pump 31 to draw in air and dissipate heat through the air intake port 334.

[0079] Specifically, the air inlet 334 connects to one end of the first air intake section 331, and the other end of the first air intake section 331 bends and extends through the suspension bracket 50. The end of the first air intake section 331 that passes through the suspension bracket 50 connects to one end of the second air intake section 332 located within the suspension bracket 50. The other end of the second air intake section 332 located within the suspension bracket 50 connects to one end of the third air intake section 333 that passes through the suspension bracket 50. The other end of the third air intake section 333 then connects to the air pump 31. In this way, the air intake channel 33 connects the air inlet 334 and the air pump 31 together, facilitating the air pump 31 to draw in air and dissipate heat through the air inlet 334.

[0080] Furthermore, since the suspension bracket 50 is located outside the floor brush device 100, placing the second air intake section 332 inside the suspension bracket 50 of the floor brush device 100 extends the length of the air intake channel 33, which helps to reduce the temperature of the air entering the air pump 31. At the same time, placing each part of the air intake channel 33 inside the floor brush device 100 increases the aesthetics and practicality of the floor brush device 100.

[0081] Please refer to the following: Figure 4 and Figures 8 to 10 In some embodiments, the first air intake section 331 includes a first air intake branch 335 and a second air intake branch 336 connected together, wherein the first air intake branch 335 is perpendicular to the axial direction of the roller brush 10 and is connected to the air intake 334; the second air intake branch 336 is parallel to the axial direction of the roller brush 10 and passes through the suspension bracket 50.

[0082] In this way, the first air intake section 331 is concealed within the housing 22 and the suspension bracket 50, improving the aesthetics of the floor brush device 100.

[0083] For example, one end of the first air intake branch 335 is connected to the air intake 334, and the other end of the first air intake branch 335 extends into the interior of the housing 22 perpendicular to the axial direction of the roller brush 10 (that is, perpendicular to the surface of the housing 22) and connects to one end of the second air intake branch 336. Meanwhile, the second air intake branch 336 is arranged parallel to the axial direction of the roller brush 10, and the other end of the second air intake branch 336 passes through the suspension bracket 50. The first air intake branch 335 and the second air intake branch 336 can be connected perpendicularly to each other, or they can be connected by a smooth curve at the connection point. This application does not limit the implementation of the embodiment to meet various needs.

[0084] Please see Figure 11 In some embodiments, there are multiple first intake branches 335 and intake ports 334, and all of the multiple first intake branches 335 are connected to second intake branches 336.

[0085] Thus, the arrangement of multiple air inlets 334 can increase the air intake area and effectively suppress the heat generation of the drive component 20.

[0086] For example, multiple air inlets 334 are disposed on the surface of the housing 22, and the multiple air inlets 334 can be arranged sequentially along a direction perpendicular to the axis of the roller brush 10. That is to say, the projection of the multiple air inlets 334 in the vertical direction after being connected in sequence is perpendicular to the projection of the axis of the roller brush 10 in the vertical direction. At the same time, the multiple air inlets 334 are respectively connected to multiple first air intake branches 335, and the multiple first air intake branches 335 extend perpendicularly to the surface of the housing 22 into the interior of the housing 22, and finally connect with the second air intake branch 336.

[0087] It should be noted that the connection angle between the first air intake branch 335 and the second air intake branch 336 can be vertical, obtuse, acute, or a continuous arc, etc. The air intakes 334 can be evenly arranged around the housing 22 in the rotation direction of the roller brush 10, or concentrated at a certain position of the housing 22 in the rotation direction of the roller brush 10 (for example, multiple air intakes 334 can be concentrated on the upper or lower side of the housing 22, etc.). The embodiments of this application do not limit this, in order to meet various needs.

[0088] In addition, multiple air inlets 334 can be arranged sequentially along a direction parallel to the axis of the roller brush 10. At the same time, multiple air inlets 334 are connected to multiple first air intake branches 335 respectively. Multiple first air intake branches 335 are perpendicular to the surface of the housing 22 and extend into the interior of the housing 22, and finally connect with the second air intake branch 336.

[0089] The embodiments of this application do not limit the specific arrangement of the first air intake branch 335 and the specific number of air intakes 334. The projection of multiple air intakes 334 in the vertical direction and the projection of the axis of the roller brush 10 in the vertical direction can be perpendicular, parallel or intersecting at a certain angle. The number of air intakes 334 can be 2, 3, 4 or other types to meet various needs.

[0090] Please see Figure 5 and Figure 6 In some embodiments, the second air intake section 332 is integrated within the suspension bracket 50 and integrally formed with the suspension bracket 50.

[0091] This ensures that the material and structural strength between the second air intake section 332 and the suspension bracket 50 remain consistent at the connection point, thereby improving the airtightness of the second air intake section 332.

[0092] Specifically, the second air intake section 332 and the suspension bracket 50 are a seamless or nearly seamless integral continuous structure to ensure the airtightness of the second air intake section 332.

[0093] Please see Figure 4 and Figure 5 In some embodiments, the air inlet 334 is located on the side of the roller brush 10 away from the ground along its central axis.

[0094] This prevents water from entering the air intake channel 33 through the air inlet 334 when cleaning the roller brush 10.

[0095] Specifically, in the vertical direction, the air inlet 334 is located at the upper part of the roller brush 10, that is, the air inlet 334 is located on the side of the roller brush 10 away from the ground along its central axis. Because the lower part of the roller brush 10 needs to be immersed in water for cleaning, positioning the air inlet 334 at the upper part of the roller brush 10 prevents water from flowing into the air intake channel 33 during cleaning, thus avoiding any impact on the spray assembly 30 and increasing the operational stability and service life of the spray assembly 30.

[0096] Of course, in some embodiments, the roller brush 10 does not need to be immersed in water when cleaning the roller brush 10, so that even if the air inlet 334 is located on the side of the central axis of the roller brush 10 close to the ground, it will not affect the function and reliability of the floor brush device 100. In this case, the air inlet 334 can be located on either side of the central axis of the roller brush 10.
