[0006] In an example embodiment of the utility model, the fan comprises a flow guide piece, the flow guide piece is connected with the first air outlet and the second air inlet, and the airflow direction of the first air outlet is not parallel to the airflow direction of the second air inlet.

[0014] In an example embodiment of the utility model, the flow guide piece comprises a grid, the grid is arranged at the connection position of the flow guide piece and the dust box, and the grid seals one side of the clamping groove.

[0023] The base station of this application can accommodate cleaning equipment for charging, cleaning, or waste removal. The control board of the suction device within the cleaning equipment is independently located from the fan, which improves the situation where interference between the control board and other components restricts the fan's placement angle. This increases the space utilization of the cleaning equipment, reduces obstruction of the first air outlet, enhances the fan's suction effect on the dust box, and consequently improves the dust box's suction efficiency, thus enhancing the cleaning effect on the surface to be cleaned. The control board's shape is also freed from the fan's limitations, allowing for a more regular shape and size, effectively improving the space utilization of the cleaning equipment and facilitating its layout within the space.

[0046] Please see Figures 1 to 9 This utility model provides a suction device, a cleaning equipment, and a cleaning system. The suction device is used for cleaning equipment and includes a dust box 100, a fan 200, and a control board 300. The dust box 100 is provided with a first air inlet 110 and a first air outlet 120; the fan 200 includes a second air inlet 210 and a second air outlet 220, the second air inlet 210 being connected to the first air outlet 120 so that the fan 200 can draw gas from the dust box 100 through the first air outlet 120; the control board 300 is independent of the fan 200 and is electrically connected to the fan 200.

[0047] The fan 200 of this application draws air from the dust box 100 through the first air outlet 120, allowing dust and particles to enter the dust box 100 through the first air inlet 110 for cleaning the surface to be cleaned. The control board 300 is independently positioned from the fan 200, which improves the situation where interference between the control board 300 and other components restricts the placement angle of the fan 200. By adjusting the angle of the fan 200, space utilization can be improved, obstruction of the first air outlet 120 can be reduced, and the suction effect of the fan 200 on the dust box 100 can be enhanced, thereby improving the suction effect of the dust box 100 and improving the cleaning effect on the surface to be cleaned.

[0048] The control board 300 is independent of the fan 200, and its shape is also freed from the limitations of the fan 200. The shape and size of the control board 300 can be more regular; for example, its shape can be designed as rectangular, circular, or other shapes as needed, effectively improving the space utilization of the cleaning equipment and facilitating its layout within the space. Being independent of the fan 200, the control board 300 can also be placed in areas conducive to heat dissipation and waterproofing, improving its operational stability, reducing malfunctions, extending its service life, and lowering the failure rate of the cleaning equipment.

[0049] The suction device involved in this application is installed in a cleaning device, which can be a sweeping robot, a cleaning robot, etc., but is not limited to these. Taking a cleaning robot as an example, in order to perform its cleaning function, the cleaning device at least includes a suction device for collecting and removing dust and debris from the ground. Specifically, the suction device includes a dust box 100 and a fan 200 connected to the dust box 100. The fan 200 generates negative pressure by rotating at high speed, sucking the dust and debris into the dust box 100. To improve cleaning efficiency, the dust and debris are pre-collected. In some embodiments, the suction device is also equipped with a cleaning component such as a roller brush mechanism. The roller brush mechanism can include a roller brush drive and a roller brush. The roller brush drive can drive the roller brush to rotate, so as to move the dust and debris on the cleaning surface within the cavity of the roller brush mechanism. Then, the negative pressure is used to suck the dust and debris into the dust box 100, thereby improving the cleaning effect of the cleaning component on dust, particulate matter, and other dirt on the cleaning surface.

[0050] In some embodiments, the cleaning equipment further includes a wet cleaning device for wet cleaning, which includes a cleaning head, a liquid storage tank, a pump body, and piping components. In other embodiments, the cleaning equipment also includes an intelligent control system, which can integrate various functions according to actual needs. These functions may include, but are not limited to, autonomous travel planning based on sensors such as accelerometers, gyroscopes, and odometers; obstacle recognition and collision avoidance based on distance sensors and image recognition devices; autonomous walking based on mechanical mechanisms such as drive wheel sets, driven wheel sets, and drivers; human-computer interaction based on physical buttons, virtual buttons, displays, and indicator lights; energy supply based on rechargeable batteries; and intelligent control based on control circuits or control chips, etc., which will not be elaborated further.

[0051] In one example of the dustbin 100 involved in this application, the shape of the dustbin 100 can be rectangular, circular, polygonal, or other shapes, and this application does not limit it. In this embodiment, the dustbin 100 is roughly in the shape of a horizontally placed polygonal prism. This placement method can be reasonably arranged with other components in the cleaning equipment, achieving a high utilization rate in a limited space.

[0052] In one embodiment, a filter assembly is provided inside the dust box 100, which divides the inner cavity of the dust box 100 into a first chamber and a second chamber. A first air inlet 110 and a first air outlet 120 are respectively located on the cavity walls of the first and second chambers. For example, the first air inlet 110 is located on the cavity wall of the first chamber, and the first air outlet 120 is located on the cavity wall of the second chamber. The filter assembly filters the airflow drawn into the dust box 100 through the first air inlet 110, reducing the amount of dust entering the fan 200 and reducing the failure rate of the fan 200. The installation position of the filter assembly is not limited; for example, it can be placed horizontally, vertically, or at a certain angle to the horizontal. There are various installation methods for the filter assembly, including but not limited to threaded connection, snap-fit, or plug-in connection, as long as it can effectively divide the inner cavity of the dust box 100 into a first chamber and a second chamber.

[0053] In one embodiment, a baffle is rotatably provided at the first air inlet 110 to cover the first air inlet 110 when not in operation, so as to prevent dust and debris from overflowing from the first air inlet 110.

[0054] In one embodiment, the fan 200 includes a motor, an impeller, and a guide vane 230. The motor drives the impeller to rotate, thereby converting mechanical energy into the kinetic and pressure energy of the gas, so as to realize the flow of gas from the second air inlet 210 to the second air outlet 220. The impeller is radially shaped, and the gas gains centrifugal force in the impeller, thus forming an airflow.

[0055] Of course, as some alternatives, the impeller can also be propeller-shaped, or the impeller can be a mixed flow fan 200 impeller, etc., to achieve the suction of gas in the dust box 100.

[0056] Please see Figure 3 In one embodiment, the air guide 230 guides the airflow. The air guide 230 connects the first air outlet 120 and the second air inlet 210. That is, the airflow flows through the first air outlet 120 and the air guide 230 in sequence and then flows into the second air inlet 210. By connecting the first air outlet 120 and the second air inlet 210 through the air guide 230, the airflow direction can be changed, which makes it easier to set up the fan 200. This not only makes reasonable use of the space inside the cleaning equipment, but also reduces the obstruction of the first air outlet 120 by the fan 200, increases the effective ventilation area of ​​the first air outlet 120, and improves the suction effect of the cleaning equipment.

[0057] Please see Figure 3 and Figure 9 In one embodiment, the first air outlet 120 is located on the top of the side wall of the dust box 100, and the airflow direction at the first air outlet 120 is basically horizontal. The impeller diameter is typically larger than the motor diameter, therefore the overall outer diameter of the fan 200 is relatively large. Furthermore, due to the impeller's exhaust requirements, the second air outlet 220 also needs to be located on the outer periphery of the fan 200, resulting in a large radial space occupied by the fan 200. If the fan 200 is placed horizontally, i.e., its axis is horizontal or substantially horizontal, the fan 200 will occupy a large longitudinal space, leaving less longitudinal space for the cleaning components. The horizontal placement of the fan 200 is also unfavorable for the arrangement of other components in the cleaning equipment. Since the airflow direction of the first air outlet 120 is not parallel to the airflow direction of the second air inlet 210, the fan 200 is placed vertically or inclined in the longitudinal direction. In other words, the axis of the fan 200 is vertical or basically vertical, which effectively utilizes the horizontal space of the cleaning equipment, reduces the vertical space occupied by the fan 200, facilitates the use of space inside the cleaning equipment, and avoids the situation where the height of the cleaning equipment is too high.

[0058] Please see Figure 7In one embodiment, the guide member 230 forms a guide air duct 231 between the first air outlet 120 and the second air inlet 210. The depth of the first side 232 of the guide air duct 231 is greater than the depth of the second side 233 of the guide air duct 231. The first side 232 and the second side 233 are opposite sides of the guide air duct 231 near the first air outlet 120. Due to the limited space inside the cleaning equipment, the fan 200 usually needs to be close to the first air outlet 120 of the dust box 100. The depth of the first side 232 of the guide air duct 231 is greater than the depth of the second side 233. The guide member 230 is inclined at the first air outlet 120, and there is an angle between the motor axis and the vertical direction, thereby reducing the obstruction of the first air outlet 120 by the motor and impeller, increasing the effective ventilation area of ​​the first air outlet 120, and improving the suction effect of the cleaning equipment.

[0059] The existing control board 300 is integrated with the fan 200. Since some components on the upper part of the control board 300 protrude, the tilted setting of the fan 200 can easily cause the control board 300 to interfere with other components of the cleaning equipment. By making the control board 300 and the fan 200 independent, the fan 200 can be tilted so that the depth of the first side 232 is greater than the depth of the second side 233, reducing the obstruction of the first air outlet 120, thereby increasing the effective ventilation area and improving the suction effect of the cleaning equipment.

[0060] Please see Figure 3 and Figure 8 In one embodiment, the guide duct 231 gradually decreases in depth along the direction from the first air outlet 120 to the second air inlet 210. The guide duct 231 is a spiral-shaped duct, and the direction of the guide duct 231 from the first air outlet 120 to the second air inlet 210 is the same as the direction along the spiral-shaped duct from the first air outlet 120 to the second air inlet 210. The guide duct 231 can effectively convert the kinetic energy of the high-speed airflow thrown out by the impeller into static pressure, guide the airflow to flow smoothly, reduce airflow vortices and turbulence, thereby reducing energy loss. The gradually decreasing depth and smaller cross-section of the guide duct 231 can significantly improve airflow efficiency, reduce noise, and enhance airflow stability, thereby ensuring a stable suction effect of the cleaning equipment.

[0061] Please see Figure 5In one embodiment, the fan 200 further includes an airflow guide 240 disposed on the outer periphery of the impeller, and a second air outlet 220 disposed on the airflow guide 240. The airflow guide 240 guides the airflow generated by the impeller to the second air outlet 220 for outflow, making the airflow direction at the second air outlet 220 horizontal or substantially horizontal. The air outlet of existing cleaning equipment is connected to the air outlet of the fan 200. Existing fans 200 are typically vertically mounted, therefore their air outlets are usually horizontal. In this application, the control board 300 is independently mounted from the fan 200, allowing the fan 200 to be tilted to reduce obstruction of the first air outlet 120. If the airflow guide 240 is not used, the second air outlet 220 of the fan 200 will tilt with the tilt of the fan 200, resulting in a mismatch with the air outlets of existing cleaning equipment. By setting up the airflow guide component 240, the second air outlet 220 can be matched with the air outlet of existing cleaning equipment, improving the universality of accessories and reducing the modification cost of cleaning equipment.

[0062] Please see Figure 9 In one embodiment, the dust box 100 includes a slot 130, which is disposed at the connection between the dust box 100 and the flow guide 230. The slot 130 is configured to install a filter element. The filter element can further filter dust, debris, etc., in the dust box 100, preventing impurities from entering the fan 200 and causing the fan 200 to jam, thus reducing the failure rate of the fan 200. The slot 130 facilitates the installation of the filter element, prevents the filter element from falling off, and effectively utilizes the function of the filter element.

[0063] Of course, in other embodiments, the connection between the dust box 100 and the guide member 230 may not be provided with a separate filter. Instead, the dust can be filtered by the filter assembly provided in the dust box 100 to prevent dust from entering the fan 200.

[0064] Please see Figure 3 In one embodiment, the flow guide 230 includes a grille 234, which is disposed at the connection between the flow guide 230 and the dust box 100, and the grille 234 blocks one side of the slot 130. The grille 234 of the cleaning equipment can improve the strength of the connection between the flow guide 230 and the dust box 100 and improve the situation where the grille 234 is easily deformed under the impact of airflow.

[0065] Please see Figure 9In one embodiment, the dust box 100 includes a third air inlet 140 and a third air outlet 150. The third air inlet 140 is located at one end of the length direction of the dust box 100, and the third air outlet 150 is located at the other end of the length direction of the dust box 100. The third air inlet 140 and the third air outlet 150 are used to remove dust from the dust box 100, so as to discharge dust, debris, etc. inside the dust box 100. A filter assembly needs to be installed inside the dust box 100. By forming an airflow between the third air inlet 140 and the third air outlet 150, the dust, debris, etc. adsorbed on the filter assembly can be blown away, thereby cleaning the inside of the dust box 100. The third air inlet 140 and the third air outlet 150 are respectively located at both ends of the length direction of the dust box 100, so the cross-section of the airflow channel between the third air inlet 140 and the third air outlet 150 is small, the flow velocity is increased, which is more conducive to blowing out the dust inside the dust box 100.

[0066] In one embodiment, baffles are rotatably provided at both the third air inlet 140 and the third air outlet 150 to cover the third air inlet 140 and the third air outlet 150 when not in operation, so as to prevent dust and debris from overflowing through the third air inlet 140 and the third air outlet 150.

[0067] In one embodiment, the third air inlet 140 and the third air outlet 150 are respectively disposed on the cavity walls of the first chamber and the second chamber, and the third air inlet 140 and the first air outlet 120 are disposed on the cavity wall of the same chamber, and the third air outlet 150 and the first air inlet 110 are disposed on the cavity wall of the same chamber. Taking the first air inlet 110 disposed on the cavity wall of the first chamber as an example, when the surface to be cleaned is cleaned, the airflow passes sequentially through the first air inlet 110, the first chamber, the filter assembly, the second chamber, and the first air outlet 120. Dust and debris are trapped in the first chamber by the filter assembly, and some of them adhere to the side of the filter assembly facing the first chamber. When the dust box 100 needs to be cleaned, the airflow passes through the third air inlet 140, the second chamber, the filter assembly, the first chamber, and the third air outlet 150 in sequence. Since the third air inlet 140 and the first air inlet 110 are located in different chambers, while discharging the dust in the chamber of the dust box 100, the dust attached to the filter assembly can be effectively cleaned and discharged, improving the dust removal effect and ensuring cleanliness.

[0068] For example, the control board 300 is electrically connected to the fan 200. The connection method can be direct wiring or electrical connection through terminal blocks to facilitate the electrical connection between the control board 300 and the fan 200, so as to realize the control board 300 control the fan 200.

[0069] For example, the control board 300 has several electronic components. The main body of the control board 300 can be a rectangular board, a circular board, a polygonal board or other regular board, or it can be an irregular board, depending on the spatial layout requirements of the cleaning equipment.

[0070] A second aspect of this invention provides a cleaning device, comprising a base, a cleaning component, and any one of the aforementioned suction devices. The cleaning component is installed in the base and is provided with an air intake; the suction device is installed in the base, and a first air inlet 110 is connected to the air intake.

[0071] The cleaning equipment of this application includes, but is not limited to, sweeping robots and vacuum cleaners. The cleaning components of the cleaning equipment are installed in the base body. The air intake is connected to the suction device. The fan 200 draws air from the dust box 100, causing the airflow at the cleaning components to pass through the air intake and the first air inlet 110 before entering the dust box 100, thereby temporarily storing dust and debris. The control board 300 of the suction device is set independently of the fan 200, which can improve the situation where interference between the control board 300 and other components restricts the placement angle of the fan 200, thereby improving the space utilization of the cleaning equipment, reducing obstruction of the first air outlet 120, improving the suction effect of the dust box 100, and enhancing the cleaning effect on the surface to be cleaned. The shape of the control board 300 is also freed from the limitations of the fan 200; the shape and size of the control board 300 can be more regular, effectively improving the space utilization of the cleaning equipment and facilitating its layout within the space. The control board 300 is independent of the fan 200. It can also be placed in an area that is conducive to heat dissipation and waterproofing, which reduces the failure of the control board 300 and extends the service life of the cleaning equipment.

[0072] In one embodiment of the cleaning equipment, the base includes a mounting member 400, on which the control board 300 and the fan 200 are respectively mounted. The control board 300 is located beside the fan 200. The mounting member 400 is used to fix the cleaning assembly to the base. The mounting member 400 can provide mounting positions for the dust box 100, the fan 200, and the control board 300, enabling the separate fixing of each component in the cleaning assembly. For example, the control board 300 is mounted beside the fan 200 to avoid affecting the installation of the fan 200.

[0073] A third aspect of this utility model provides a cleaning system, which includes the aforementioned cleaning equipment and a base station (not shown in the figure) adapted to the cleaning equipment. The base station of this application can accommodate the cleaning equipment for charging, cleaning, or draining it. The control board 300 of the suction device in the cleaning equipment is independently set away from the fan 200, which can improve the situation where interference between the control board 300 and other components restricts the placement angle of the fan 200, thereby improving the space utilization of the cleaning equipment, reducing obstruction of the first air outlet 120, improving the suction effect of the dust box 100, and enhancing the cleaning effect on the surface to be cleaned.

[0074] In one embodiment of the cleaning system, the base station further includes a blower generator, which includes an air outlet that can communicate with the third air inlet 140. Air is blown into the dust box 100 through the third air inlet 140 to achieve self-cleaning of the filter components and to blow dust and debris from the dust box 100 into an external dust collection device, thereby achieving self-cleaning of the dust box 100. The blower generator can be any structure capable of generating high-pressure air, such as an air compressor or a blower 200, etc., which will not be described in detail here.

[0075] In one embodiment of the cleaning system, the base station includes a dust collection device, which includes a suction component and a dust collection bag. The suction component is connected to a third air outlet 150 and is able to suck the dust collected in the dust box 100 into the dust collection bag.

[0076] The suction device involved in this application has a control board 300 independently set off from the fan 200. This improves the situation where interference between the control board 300 and other components restricts the placement angle of the fan 200, thereby increasing the space utilization of the cleaning equipment, reducing obstruction of the first air outlet 120, improving the suction effect of the dust box 100, and enhancing the cleaning effect on the surface to be cleaned. The shape of the control board 300 is also freed from the limitations of the fan 200; its shape and size can be more regular, effectively improving the space utilization of the cleaning equipment and facilitating its layout within the space. The control board 300's independence from the fan 200 also allows it to be placed in areas conducive to heat dissipation and waterproofing, reducing the likelihood of malfunctions and extending the service life of the cleaning equipment. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus possessing high utilization value and practical significance.

[0077] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
