Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and more particularly to a floor brush device. Background Technology

[0002] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0003] In related technologies, cleaning equipment typically uses a floor brush device to clean the surface to be cleaned. The floor brush device sucks in debris and waste through the air inlet while it is constantly moving.

[0004] However, the air inlet is easily clogged when it sucks in garbage and debris, affecting its cleaning function. Utility Model Content

[0005] This application provides a floor brush device to solve the technical problem that the air inlet is easily clogged when it sucks in garbage and debris, which affects the cleaning function.

[0006] This application provides a floor brush device, which includes a device body and a flow guiding structure. The device body has a floor brush air duct and a first cavity. The floor brush air duct has an air inlet. The first cavity is connected to the air inlet and is open towards the bottom of the device body. The flow guiding structure is connected to the device body.

[0007] Along the cleaning direction of the floor brush device, a flow guiding structure is disposed on the front side of the first cavity, and at least part of the structure extends into the first cavity. The flow guiding structure is configured to guide external airflow into the first cavity.

[0008] The floor brush device provided in this application sucks up the debris and impurities on the surface to be cleaned corresponding to the first cavity through the air inlet. Along the cleaning direction of the floor brush device, a guide structure is provided on the front side of the first cavity. The guide structure extends into the first cavity and can guide the airflow direction to prevent debris and impurities from entering the air inlet from different directions at the same time, thus preventing the air inlet from becoming blocked.

[0009] As an optional implementation, the flow guiding structure includes a first flow guiding part and at least one second flow guiding part. The first flow guiding part is disposed in the first cavity, is disposed opposite to the air inlet, and extends along the cleaning direction of the floor brush device to separate the air inlet. The second flow guiding part is disposed on the front side of the first cavity, and the second flow guiding part protrudes downward relative to the bottom wall of the device body.

[0010] With this configuration, the first and second guide sections can prevent garbage and debris from entering the air inlet simultaneously from the left, right, and front sides, thus preventing blockage of the air inlet.

[0011] As an optional implementation, the first guide portion extends vertically downwards perpendicular to the top wall of the first cavity.

[0012] With this configuration, the first guide section can divide the first cavity into two parts, allowing the airflow on both sides of the air inlet to enter the air inlet from both sides of the first guide section, thus reducing turbulence.

[0013] As an alternative implementation, along the cleaning direction of the floor brush device, the height of the lower edge of the first guide portion gradually increases from the front edge of the first cavity towards the interior of the first cavity.

[0014] This setup reduces turbulence and prevents debris from clogging the air inlet.

[0015] As an optional implementation, a first guide portion is disposed in the middle of the air inlet along the width direction of the device body, and the first guide portion divides the air inlet into two air inlet zones arranged along the width direction of the device body.

[0016] This configuration, by dividing the air inlet into two equal air intake zones through the first air guide section, can balance the airflow distribution and reduce the risk of blockage.

[0017] As an optional implementation, the distance between the bottom of the second guide section and the surface to be cleaned is less than or equal to 3 mm.

[0018] This design prevents large particles of debris from directly entering the air inlet through the gap between the second guide section and the surface to be cleaned, thus preventing air inlet blockage.

[0019] As an optional implementation, the bottom of the first guide portion is higher than the bottom of the second guide portion, or the bottom of the first guide portion and the bottom of the second guide portion are at the same height.

[0020] This design ensures that small debris such as hair and dust passing through the bottom of the first guide section will not be blocked by the second guide section, and can enter the air intake along the bottom of the second guide section.

[0021] As an optional implementation, there are multiple second air guides, which are arranged at intervals along the width direction of the floor brush device to form multiple air intake channels; the width of the second air guides gradually decreases along the cleaning direction of the floor brush device.

[0022] This design, with its multiple air intake channels, prevents debris and other contaminants from accumulating in the air intake and causing blockages.

[0023] As an optional implementation, the first cavity has airflow inlets at both ends along its length, and the airflow inlets connect the first cavity to the external space of the first cavity.

[0024] With this design, the airflow can pick up debris and enter the first chamber through the airflow inlet, improving cleaning efficiency.

[0025] As an optional implementation, the floor brush device further includes a first scraping assembly, a second scraping assembly, and a water spraying module; the first scraping assembly and the second scraping assembly are both connected to the main body of the device and are distributed back and forth at intervals along the cleaning direction of the floor brush device, and are arranged to form a second cavity; the water spraying module is located between the first scraping assembly and the second scraping assembly, and the water spraying module is configured to spray cleaning water onto the surface to be cleaned corresponding to the second cavity.

[0026] The first scraping component and the second guide portion form a first cavity, which is located in front of the second cavity along the cleaning direction of the floor brush device.

[0027] This setup allows for further cleaning of the surface to be cleaned via a water spray module and two scraping components, improving the cleaning effect.

[0028] This application provides a floor brush device, comprising a main body and a flow guiding structure. The main body has a floor brush duct and a first cavity. The floor brush duct has an air inlet. The first cavity is connected to the air inlet and is open towards the lower part of the main body. The flow guiding structure is connected to the main body. Along the cleaning direction of the floor brush device, the flow guiding structure is disposed on the front side of the first cavity, and at least a portion of the structure extends into the first cavity. The flow guiding structure is configured to guide external airflow into the first cavity. The floor brush device provided by this application can guide the airflow direction through the flow guiding structure, preventing debris from entering the air inlet from different directions simultaneously and causing blockage of the air inlet.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0043] In related technologies, cleaning equipment typically uses a floor brush device to clean the surface to be cleaned. The floor brush device is equipped with an air inlet, which generates negative pressure suction when working, sucking in garbage and debris along the way and collecting it in the floor brush device.

[0044] However, when the air intake is drawing air in, debris and other waste from all directions will converge towards the air intake. When there are many large particles of debris, the air intake can easily become blocked, affecting the normal cleaning function of the floor brush device.

[0045] To address the aforementioned technical problems, this application provides a floor brush device. The floor brush device has a first cavity, and the top wall of the first cavity is provided with an air inlet. The air inlet can suck in debris and dirt from the surface to be cleaned in front of the first cavity. A flow guiding structure is provided on the front side of the first cavity, and part of the flow guiding structure extends into the first cavity. The flow guiding structure can guide the direction of airflow, thereby preventing debris and dirt carried by the airflow from entering the air inlet from different directions at the same time, causing blockage of the air inlet.

[0046] The following is an example illustrating the application scenarios of the floor brush device provided in the embodiments of this application.

[0047] The floor brush device provided in this application embodiment is applied in cleaning equipment and is a cleaning structure in the cleaning equipment that comes into contact with the surface to be cleaned. The product type of the cleaning equipment in this application embodiment may include, but is not limited to, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners. Depending on the different product types, the cleaning equipment provided in this application embodiment can be used to clean various types of floors and other surfaces. This application embodiment does not make any specific limitations in this regard.

[0048] Figure 1 This is a schematic diagram of the structure of the floor brush device provided in the embodiments of this application; Figure 2 This is a schematic diagram of the bottom of the floor brush device provided in an embodiment of this application.

[0049] Reference Figure 1 and Figure 2As shown, this application embodiment provides a floor brush device 10, which includes a device body 100 and a flow guiding structure 200. The device body 100 has a floor brush air duct 110 and a first cavity 120. The floor brush air duct 110 has an air inlet 121. The first cavity 120 is connected to the air inlet 121 and is open towards the lower part of the device body 100. The flow guiding structure 200 is connected to the device body 100. Along the cleaning direction of the floor brush device 10, the flow guiding structure 200 is disposed on the front side of the first cavity 120, and at least a portion of the structure extends into the first cavity 120. The flow guiding structure 200 is configured to guide external airflow into the first cavity 120.

[0050] It should be noted that the main body 100 of the device may be equipped with a suction unit. When the floor brush device 10 is started, the suction unit starts to work. The suction unit is connected to the air inlet 121 through the floor brush air duct 110, so that the air inlet 121 generates negative pressure. The air inlet 121 is connected to the first cavity 120, and the first cavity 120 also generates negative pressure. The garbage and debris on the surface to be cleaned in the first cavity 120 and the garbage and debris on the front side of the first cavity 120 along the cleaning direction will enter the air inlet 121 along the first cavity 120 under the action of negative pressure suction, and enter the garbage collection device through the floor brush air duct 110.

[0051] It should be noted that the air inlet 121 is located in the middle of the first cavity 120 along the width direction of the main body 100 of the device. After the fan unit is started, the airflow picks up garbage and debris and enters the air inlet 121 from both sides. At the same time, since the first cavity 120 is connected to the front space of the floor brush device 10 through the guide structure 200, the garbage and debris on the front side of the floor brush device 10 will also enter the first cavity 120 through the guide structure 200 under the action of the airflow. By guiding the airflow through the guide structure 200, it can prevent multiple airflows from simultaneously carrying garbage and debris to the air inlet 121, so that the air inlet 121 is blocked by garbage and debris.

[0052] The cleaning direction of the floor brush device 10 is perpendicular to the width direction of the device body 100, and the width direction of the device body 100 is perpendicular to... Figure 1 The orientation of the paper.

[0053] As one possible implementation, the flow guiding structure 200 includes a first flow guiding section 210 and at least one second flow guiding section 220. The first flow guiding section 210 is disposed in the first cavity 120, and is disposed opposite to the air inlet 121 and extends along the cleaning direction of the floor brush device 10 to separate the air inlet 121. The second flow guiding section 220 is disposed on the front side of the first cavity 120, and the second flow guiding section 220 protrudes downward relative to the bottom wall of the device body 100.

[0054] As one possible implementation, the first guide section 210 extends vertically downwards perpendicular to the top wall of the first cavity 120.

[0055] It is understandable that the first guide section 210 can be a sheet-like baffle. While the first guide section 210 extends along the cleaning direction of the floor brush device 10, it also extends vertically downward perpendicular to the top wall of the first cavity 120. The thickness direction of the first guide section 210 is the width direction of the device body 100. The thickness of the first guide section 210 is small, so it has little impact on the ventilation area of ​​the air inlet 121. After the first guide section 210 separates the air inlet 121, when the air inlet 121 draws air, garbage and debris are drawn from both sides of the air inlet 121 by the airflow. Due to the obstruction of the first guide section 210, the two airflows in opposite directions can directly enter the air inlet 121 under the guidance of the first guide section 210. This can prevent the two airflows in opposite directions from merging and causing turbulence, which would cause large particles of garbage and debris to accumulate in the air inlet 121 and block the air inlet 121. At the same time, the first guide section 210 can prevent the large particles of debris carried by the airflow from colliding with each other and forming larger particles of debris when the two airflows in opposite directions merge, thus blocking the air inlet 121.

[0056] The top of the first guide section 210 can be connected to the top wall of the first cavity 120, the side of the first guide section 210 can be connected to the side wall of the first cavity 120, the first guide section 210 can be integrally formed with the wall of the first cavity 120, or it can be detachably connected to the wall of the first cavity 120.

[0057] It should be noted that, along the cleaning direction of the floor brush device 10, at least one second guide section 220 is located in front of the air inlet 121. Since the second guide section 220 is convex downward relative to the bottom wall of the device body 100, the distance between the bottom of the second guide section 220 and the surface to be cleaned is small. Only small particles such as dust and hair can pass through. Large particles are blocked by the second guide section 220, follow the airflow around the second guide section 220 and enter the first cavity 120, and then enter the air inlet 121 from both sides. This avoids large particles from directly entering from the front of the air inlet 121 and colliding with the garbage and debris on both sides of the air inlet 121, thereby blocking the air inlet 121.

[0058] As one possible implementation, along the cleaning direction of the floor brush device 10, the height of the lower edge of the first guide section 210 gradually rises from the front edge of the first cavity 120 toward the interior of the first cavity 120.

[0059] Understandably, along the cleaning direction of the floor brush device 10, the lower edge of the first guide section 210 gradually transitions from near the air inlet 121 to near the surface to be cleaned. When the airflow flows from the front side of the first cavity 120 to the first cavity 120, the debris and waste on the tape may adhere to the lower edge of the first guide section 210. Since the lower edge of the first guide section 210 has a slope, the debris and waste adhering to the lower edge of the first guide section 210 can enter the air inlet 121 along the slope under the influence of the airflow, and will not accumulate on the lower edge of the first guide section 210.

[0060] The first guide section 210 can be a sheet-like rib, and the shape of the sheet-like rib can be trapezoidal, triangular, arc-shaped, etc., which are not specifically limited in the embodiments of this application.

[0061] It should be noted that, along the cleaning direction of the floor brush device 10, the length of the first guide section 210 is less than the length of the air inlet 121, so that garbage and debris can directly enter the air inlet 121 along the lower edge of the first guide section 210, without getting stuck between the first guide section 210 and the side wall of the first cavity 120.

[0062] For example, when hair stretches across both sides of the thickness direction of the first guide portion 210, if the lower edge of the first guide portion 210 is parallel to the surface to be cleaned, the hair will continue to adhere tightly to the lower edge of the first guide portion 210 under the suction of the air inlet 121. As the hair gradually accumulates, it will entangle other debris and cause the air inlet 121 to become blocked. If the lower edge of the first guide portion 210 has an arc and smoothly transitions to the air inlet 121, the hair will enter the air inlet 121 under the influence of the airflow, reducing the probability of blockage.

[0063] As one possible implementation, along the width direction of the device body 100, the first guide section 210 is disposed in the middle of the air inlet 121, and the first guide section 210 divides the air inlet 121 into two air inlet zones arranged along the width direction of the device body 100.

[0064] Understandably, the first air guide section 210 is located in the middle of the air inlet 121, which can make the width of the two air inlet areas equal and avoid the possibility of blockage due to the small area of ​​one air inlet area.

[0065] As one possible implementation, the bottom of the second guide section 220 is less than or equal to 3 mm from the surface to be cleaned.

[0066] It is understandable that controlling the distance between the bottom of the second guide section 220 and the surface to be cleaned to be less than or equal to 3mm can prevent debris with a particle size greater than 3mm from directly entering the first cavity 120 from the bottom of the second guide section 220 and causing blockage of the air inlet 121.

[0067] As one possible implementation, the bottom of the first guide section 210 is higher than the bottom of the second guide section 220, or the bottom of the first guide section 210 and the bottom of the second guide section 220 are at the same height.

[0068] like Figure 1 In the vertical direction, the bottom of the first guide section 210 is higher than the bottom of the second guide section 220. The height difference between the bottom of the first guide section 210 and the bottom of the second guide section 220 is X. In some embodiments, the bottom of the first guide section 210 may also be at the same height as the bottom of the second guide section 220, so that the garbage and debris entering from the bottom of the second guide section 220 can enter the air inlet 121 along the bottom of the first guide section 210, preventing the first guide section 210 from blocking the garbage and debris from entering the air inlet 121.

[0069] As one possible implementation, there are multiple second guide sections 220, which are arranged at intervals along the width direction of the floor brush device 10 to form multiple air inlet channels 150; the width of the second guide sections 220 gradually decreases along the cleaning direction of the floor brush device 10.

[0070] It should be noted that, along the cleaning direction of the floor brush device 10, at least one second guide section 220 is located in front of the first guide section 210 and abuts against the side of the first guide section 210. The space between two adjacent second guide sections 220 forms an air intake channel 150, which can allow large particles of debris to pass through. The multiple second guide sections 220 reduce the air intake area on the front side of the first cavity 120, making the suction more concentrated at the air intake channel 150, resulting in stronger suction and improved cleaning effect. When the floor brush device 10 is working, debris on the front side of the floor brush device 10 can enter the first cavity 120 from the multiple air intake channels 150 respectively, and then enter the air intake 121 from both sides of the air intake 121 along the first cavity 120. This prevents a large amount of debris from entering the air intake 121 at the same time, thus preventing the air intake 121 from becoming clogged.

[0071] It should be noted that the second guide section 220 protrudes downward along the main body 100 of the device, and its cross-section can be triangular, arc-shaped, etc. It needs to meet the requirement that the width of the second guide section 220 gradually decreases along the cleaning direction of the floor brush device 10. That is, along the cleaning direction of the floor brush device 10, the air inlet channel 150 gradually widens, so that the air inlet channel 150 gradually narrows along the airflow direction. This trumpet-shaped tapering air inlet channel 150 can reduce energy loss and operating noise while increasing the airflow speed, and achieve a highly efficient and energy-saving cleaning effect.

[0072] For example, the number of second guide sections 220 can be 1, 2, 3, 4, 5, etc., and this application embodiment does not make a specific limitation.

[0073] As one possible implementation, both ends of the first cavity 120 in the length direction have airflow inlets 140, and the airflow inlets 140 connect the first cavity 120 and the external space of the first cavity 120.

[0074] Understandably, when the floor brush device 10 is working, the first cavity 120 generates negative pressure, and airflow passes through the air inlets 140 at both ends of the length of the first cavity 120, flowing from the air inlets 140 to the air inlets 121. During the airflow process, the debris in the first cavity 120 can be carried into the air inlets 121 from both sides. In addition, the air inlets 140 can also suck up the debris on both sides of the floor brush device 10, further improving the cleaning efficiency.

[0075] As one possible implementation, the floor brush device 10 further includes a first scraping assembly 131, a second scraping assembly 132, and a water spray module 133; the first scraping assembly 131 and the second scraping assembly 132 are both connected to the device body 100 and are distributed back and forth at intervals along the cleaning direction of the floor brush device 10, forming a second cavity 130; the water spray module 133 is located between the first scraping assembly 131 and the second scraping assembly 132, and the water spray module 133 is configured to spray cleaning water onto the surface to be cleaned corresponding to the second cavity 130; wherein, the first scraping assembly 131 and the second guide portion 220 form a first cavity 120, and along the cleaning direction of the floor brush device 10, the first cavity 120 is located in front of the second cavity 130.

[0076] Understandably, when the floor brush device 10 cleans the surface to be cleaned along the cleaning direction, the air inlet 121 of the first chamber 120 can first perform a coarse suction on the surface to be cleaned, sucking in large particles of debris and stains. As the floor brush device 10 moves, the water spray module 133 can rinse the surface to be cleaned in the second chamber 130, and work with the first scraping component 131 and the second scraping component 132 to scrape away stubborn stains and sticky debris from the surface to be cleaned. The top wall of the second chamber 130 can also be provided with a suction port, which is connected to the floor brush air duct 110. The suction port can suck in cleaning wastewater, allowing the surface to be cleaned to dry quickly.

[0077] This application provides a floor brush device 10, which includes a main body 100 and a flow guiding structure 200. The main body 100 has a floor brush air duct 110 and a first cavity 120. The floor brush air duct 110 has an air inlet 121. The first cavity 120 is connected to the air inlet 121 and is open downwards towards the main body 100. The flow guiding structure 200 is connected to the main body 100. Along the cleaning direction of the floor brush device 10, the flow guiding structure 200 is disposed on the front side of the first cavity 120, and at least a portion of the structure extends into the first cavity 120. The flow guiding structure 200 is configured to guide external airflow into the first cavity 120. The floor brush device 10 provided by this application can guide the airflow direction through the flow guiding structure 200, preventing debris from entering the air inlet 121 from different directions simultaneously and causing blockage of the air inlet 121.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
