Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and more particularly to a cleaning device and cleaning equipment. 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, vacuum cleaners typically include a suction cup and an operating body connected to the suction cup. The suction cup can be dragged on the ground, and a handle is installed on the top of the operating body. Users support and push or pull the operating body by the handle, thereby moving the suction cup. The operating body is equipped with components such as a dust collection box and a fan. The fan is used to generate negative pressure, causing the suction port on the suction cup to generate suction force to draw external dust and debris into the dust collection box.

[0004] However, current vacuum cleaners struggle to remove stubborn dust that adheres to the floor or deep within blankets, resulting in poor cleaning performance. Utility Model Content

[0005] This application provides a cleaning device and equipment that can blow up stubborn dust attached to the ground or deep in the blanket, and has a dust-raising function, thereby making it easier to suck dust into the equipment and improving the cleaning effect of the cleaning equipment.

[0006] In a first aspect, this application provides a cleaning device comprising a base; the base having a dust-collecting chamber, a dust-suction channel, and a blowing channel; the dust-collecting chamber being open downwards towards the base; a suction port and a blowing port are respectively provided on opposite sides of the dust-collecting chamber, the suction port communicating with the dust-suction channel, and the blowing port communicating with the blowing channel. The air outlet direction of the blowing port is inclined downwards towards the base relative to the horizontal direction.

[0007] The cleaning device provided in this application achieves the function of dust raising by setting up a dust raising chamber. The dust suction channel blows air out through the air outlet, thereby raising the dust in the dust raising chamber. The dust suction channel sucks in the raised dust through the air outlet. This can blow up stubborn dust attached to the ground or deep in the carpet, and make it easier to suck the dust into the dust suction channel, thus having a highly efficient and good cleaning effect.

[0008] As an optional implementation, the air intake is located on the rear side of the dust-collecting chamber along the first direction, and the air outlet is located on the front side of the dust-collecting chamber along the first direction; wherein, the first direction is the moving direction of the cleaning device during cleaning.

[0009] In this way, the air intake can suck in dust in the direction of the cleaning device's movement, while the air outlet can blow the dust attached to the ground toward the air intake, preventing dust from overflowing during the dust-raising process.

[0010] As an optional implementation, the air outlet may include a first side and a second side, with the first side and the second side being arranged adjacent to each other; the first side faces the air inlet in the horizontal direction, and the second side faces the bottom of the base in the vertical direction.

[0011] This setup increases the airflow range of the blower and ensures that the airflow is at an angle to the ground, making it easier to blow up dust.

[0012] As an alternative implementation, the second side is flush with the bottom surface of the base.

[0013] This design increases the wind pressure when the airflow hits the ground, making it easier to blow up attached dust and debris.

[0014] As an optional implementation, the dust-generating chamber extends along the second direction; there can be multiple air outlets, which are spaced apart along the extension direction of the dust-generating chamber; wherein, the second direction is perpendicular to the moving direction of the cleaning device during cleaning.

[0015] This setup expands the dust-generating area, ensuring that the area covered by the dust-generating chamber achieves better dust control and cleaning results.

[0016] As an optional implementation, multiple air outlets form multiple air blowing zones arranged at intervals along the length of the dust-generating chamber, with each air blowing zone having at least two air outlets.

[0017] This setup concentrates the airflow into the blowing area, which can locally increase the air pressure of the airflow from the air outlets, blowing away stubborn dust and deposits and improving the cleaning effect.

[0018] As an optional implementation, the air intake is positioned on the side of the dust chamber where the air outlet is located; the air intake direction of the air intake is inclined downwards from the base relative to the horizontal direction.

[0019] With this configuration, the air intake can draw in airflow in the direction the cleaning device is moving, thereby improving the efficiency of dust being drawn in.

[0020] As an optional implementation, air guide walls are provided on both sides of the air intake, and the air guide walls are set to expand into the dust chamber relative to the air intake.

[0021] This design allows dust from both ends of the dust chamber to gather towards the middle, and the air guide wall guides the airflow, allowing it to be drawn into the air intake more smoothly.

[0022] As an optional implementation, a scraper can be provided on the bottom side of the base, and the scraper is located on the rear side of the dust chamber along the moving direction of the cleaning device during cleaning; the scraper extends along the width direction of the base.

[0023] With this configuration, during the cleaning process, after the area corresponding to the dust chamber passes the surface to be cleaned, the scraping component can scrape the surface to be cleaned, ensuring that there is no dust or debris residue on the surface to be cleaned.

[0024] As an optional implementation, the base may include a first housing and a second housing; the first housing is connected above the second housing, and the two together form a dust suction channel and a blower channel; the side of the second housing away from the first housing forms a dust chamber.

[0025] This design utilizes two independent structures to form a dust extraction channel and a blower channel. The base can be molded separately, improving processing convenience and reducing costs.

[0026] As an optional implementation, in the cleaning direction of the cleaning device, an air outlet is provided on the front side of the air blowing channel, and the air blowing channel has airflow branches that are diverted from both sides of the dust suction channel and then converge again, so that the air blowing channel is arranged around the dust suction channel.

[0027] This design makes full use of the horizontal space of the base, improving space utilization and reducing the overall height of the base.

[0028] As an alternative implementation, the cleaning device may also include a dust collection box disposed within the suction channel, through which airflow entering the suction channel from the air intake flows.

[0029] This setup allows the space within the suction channel to be used to assemble the dust collection box. The airflow entering the suction channel can be filtered through the dust collection box, and dust and debris can be stored in the dust collection box.

[0030] As an optional implementation, a seal is provided on the side of the air intake facing the dust collection channel, and the seal is arranged around the edge of the air intake; the circumferential edge of the airflow inlet of the dust collection box abuts against the seal.

[0031] This setup ensures a good seal between the dust collector and the air intake.

[0032] Secondly, this application provides a cleaning device, which includes a device body and a cleaning device as described in the above technical solution. The device body is movably connected to the cleaning device. A fan assembly is provided on the device body. The fan assembly is configured to generate negative pressure airflow in the dust suction channel of the cleaning device and positive pressure airflow in the blowing channel of the cleaning device.

[0033] This application provides a cleaning device and equipment. The cleaning device includes a base; the base has a dust-collecting chamber, a dust-suction channel, and a blowing channel; the dust-collecting chamber is open downwards towards the base; a suction port and a blowing port are respectively provided on opposite sides of the dust-collecting chamber, the suction port being connected to the dust-suction channel, and the blowing port being connected to the blowing channel. The air outlet of the blowing port is inclined downwards towards the base relative to the horizontal direction, thereby blowing up stubborn dust attached to the ground or deep in the carpet, making it easier to suck the dust into the dust-suction channel, thus achieving a highly efficient and good cleaning effect.

[0055] 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.

[0056] Vacuum cleaners typically consist of a suction cup and an operating body connected to the suction cup. The suction cup can be dragged on the ground. A handle is located on the top of the operating body, allowing the user to support and push or pull the operating body to move the suction cup. The operating body contains components such as a dust collection box and a fan. The fan generates negative pressure, which creates suction at the suction nozzle on the nozzle head, thus achieving the dust collection function.

[0057] However, the negative pressure suction generated by the suction nozzle of current vacuum cleaners is limited, making it difficult to remove stubborn dust adhering to the floor or deep within carpets, resulting in poor cleaning performance. Furthermore, during cleaning, dust easily accumulates in corners and edges that the suction nozzle cannot cover, making these areas difficult to clean.

[0058] To address the aforementioned technical problems, this application provides a cleaning device and a cleaning equipment. The cleaning device is used to clean the equipment. By setting a dust-raising chamber on the side of the cleaning device facing the ground, the dust-raising function is achieved. An air outlet blows airflow towards the ground in the dust-raising chamber, thereby raising dust in the dust-raising chamber. An air suction port can suck in the raised dust. This can blow up stubborn dust attached to the ground or deep in the blanket, making it easier to suck the dust into the suction channel, thus achieving a highly efficient and good cleaning effect.

[0059] To facilitate understanding, the application scenarios of the cleaning equipment provided in the embodiments of this application will be described first.

[0060] The embodiments of this application provide cleaning equipment with a dust collection function, including but not limited to vacuum cleaners, floor scrubbers, and vacuum and mop combos. The cleaning equipment can be used for household cleaning or for floor cleaning in other indoor or outdoor scenarios. The embodiments of this application do not limit the specific product type used in the main body of the equipment or the specific application scenario of the cleaning equipment.

[0061] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 2 An exploded view of the cleaning equipment provided in the embodiments of this application; Figure 3 A bottom side view of the cleaning apparatus provided in an embodiment of this application; Figure 4 A schematic diagram of the air intake and air outlet in the cleaning device provided in the embodiments of this application; Figure 5 A cross-sectional view of the cleaning apparatus provided in the embodiments of this application; Figure 6 for Figure 5 A partial view of position A in the middle.

[0062] See Figures 1 to 6 As shown, this application provides a cleaning device 200, which includes a base. The base has a dust-collecting chamber 205, a dust-suction channel 203, and a blowing channel 204. The dust-collecting chamber 205 is open towards the lower part of the base. When the cleaning device 200 cleans the surface to be cleaned, the opening of the dust-collecting chamber 205 faces the surface to be cleaned, and the dust-collecting chamber 205 forms an area above the surface to be cleaned where dust can be collected.

[0063] The dust collection chamber 205 has an air intake 201 and an air blowing 202 on opposite sides. The air intake 201 is connected to the dust collection channel 203, and the air blowing 202 is connected to the air blowing channel 204. The airflow in the air blowing channel 204 flows out from the air blowing 202, and the airflow in the dust collection channel 203 flows in from the air intake 202.

[0064] Understandably, the air pressure at the blower 202 is greater than the ambient air pressure. The airflow from the blower 202 enters the dust-collecting chamber 205 and is directed towards the surface to be cleaned, thus raising the stubborn dust adhering to the surface. The air pressure at the suction port 201 is lower than the ambient air pressure, and the suction port 201 can then draw the dust from the dust-collecting chamber 205 into the suction channel 203.

[0065] In some embodiments, the air outlet 202 is inclined downwards from the base relative to the horizontal direction. This way, when the air outlet 202 blows air downwards into the dust collection chamber 205, the airflow direction is at a certain angle relative to the surface to be cleaned. Upon contact with the surface, the airflow more easily stirs up dust along the surface. Furthermore, the inclined airflow direction of the air outlet 202 prevents the airflow from vertically impacting the surface and causing dust to overflow around the dust collection chamber 205, thus preventing dust from leaking out of the dust collection chamber 205.

[0066] For example, the air outlet 202 is tilted downwards from the base at an angle α relative to the horizontal direction. Specific values ​​for α include, but are not limited to, 5°, 10°, 30°, 45°, 60°, 75°, 80°, and 85°. This embodiment does not specifically limit this value. The air outlet 202's tilt angle towards the surface to be cleaned reduces airflow resistance, guides the airflow from the surface to be cleaned, and improves the smoothness of the airflow from the air outlet 202.

[0067] It should be noted that in the cleaning device 200 provided in this application embodiment, airflow is blown into the dust-raising chamber 205 through the air outlet 202. The positive pressure airflow impacts the surface to be cleaned to achieve the function of dust raising. Dust can be raised in the dust-raising chamber 205. The dust suction channel 203 sucks in the raised dust through the air outlet 201. This can blow up stubborn dust attached to the ground or deep in the blanket, and make it easier to suck the dust into the dust suction channel 203. Therefore, it has a highly efficient and good cleaning effect.

[0068] In addition, compared to negative pressure vacuuming alone, the airflow in this application blows out from the blower 202 to create positive pressure dust, and works in conjunction with negative pressure vacuuming from the suction port 201. This makes it easier to blow up dust and suck it into the suction channel 203 when cleaning corners of the room and edges such as table and chair legs, thus giving the cleaning device 200 a larger effective cleaning area.

[0069] In some embodiments, the air intake 201 is located on the rear side of the dust collection chamber 205 along the first direction, and the air outlet 202 is located on the front side of the dust collection chamber 205 along the first direction. The first direction is the direction of movement of the cleaning device 200 during cleaning.

[0070] The first direction is defined as the X direction. When the cleaning device 200 performs a cleaning operation, the cleaning device 200 can move forward or backward along the X direction.

[0071] Understandably, the suction port 201 is located on the rear side of the dust-collecting chamber 205 along the X direction, and faces forward along the X direction. The suction port 201 can suck up dust in the direction of movement of the cleaning device 200, resulting in higher dust collection efficiency. Meanwhile, the blowing port 202 is located on the rear side of the dust-collecting chamber 205 along the X direction, meaning the blowing port 202 faces backward along the X direction. This blows dust adhering to the ground towards the suction port 201, preventing dust from spilling out during the dust collection process.

[0072] The specific structure of the air intake 201 will be described in detail below.

[0073] Please continue to refer to Figures 1 to 6 In one possible implementation, the air outlet 202 may include a first side 202a and a second side 202b, with the first side 202a and the second side 202b arranged adjacent to each other. The first side 202a faces the air inlet 201 in a horizontal direction, and the second side 202b faces the bottom of the base in a vertical direction.

[0074] It is understandable that the first side 202a and the second side 202b together form the air outlet area of ​​the air blower 202. This can increase the air outlet range of the air blower 202 and ensure that the airflow has an angle with the ground, making it easier to blow up dust.

[0075] For example, the first side 202a of the air outlet 202 is vertically arranged and faces the rear side along the X direction, while the second side 202b of the air outlet 202 is horizontally arranged and faces the lower part of the base along the vertical direction, making the air outlet 202 have an "L" shape. The first side 202a and the second side 202b emit air simultaneously, so that the overall air blowing direction of the air outlet 202 is tilted towards the surface to be cleaned relative to the horizontal direction.

[0076] It should be noted that, with the atmospheric pressure of the external environment as a reference, the air outlet 202 is at positive pressure and the air inlet 201 is at negative pressure. That is, the air pressure of the air outlet 202 is greater than the air pressure of the external environment, and the air pressure of the external environment is greater than the negative pressure of the air inlet 201. In this way, the airflow is achieved by using the pressure difference between the air outlet 202 and the air inlet 201.

[0077] In some embodiments, the second side 202b is flush with the bottom surface of the base. There is a certain gap between the bottom of the base and the surface to be cleaned. The fact that the second side 202b is flush with the bottom surface of the base allows the air intake 201 to be as close as possible to the surface to be cleaned when it is tilted to discharge air.

[0078] Understandably, the second side 202b is the lower edge of the air outlet 202. During the cleaning process, the second side 202b should be as close as possible to the surface to be cleaned. This can increase the air pressure when the airflow blows across the ground, making it easier to blow away stubborn dust and debris, and preventing dust from remaining on the surface to be cleaned without being blown into the dust chamber 205.

[0079] In some embodiments, the dust collection chamber 205 extends along a second direction. There may be multiple air outlets 202, which are spaced apart along the extending direction of the dust collection chamber 205. The second direction is perpendicular to the direction of movement of the cleaning device 200 during cleaning.

[0080] The second direction is defined as the Y direction, which can be the width direction of the base. The dust chamber 205 can be a long strip-shaped area extending along the Y direction. The air outlet 202 and the air suction outlet 201 are respectively set to correspond to the two long sides of the dust chamber 205.

[0081] Understandably, setting multiple air outlets 202 at intervals can expand the dust-raising area, so that the area covered by the dust-raising chamber 205 along its length can have a better dust-raising and cleaning effect.

[0082] For example, the number of air outlets 202 can be two, three, four or more, and this application embodiment does not specifically limit this.

[0083] For example, multiple air outlets 202 form multiple spaced air blowing zones 206 along the length of the dust collection chamber 205, and each air blowing zone 206 is provided with at least two air outlets 202. The air blowing zones 206 concentrate the air outlets 202, which can locally increase the air pressure of the airflow blown out by the air outlets 202, blow away stubborn dust and deposits, and improve the cleaning effect.

[0084] In some embodiments, the suction port 201 is positioned on the side facing the dust collection chamber 205 with the air outlet 202. The air intake direction of the suction port 201 is inclined downwards from the base relative to the horizontal direction. In this way, the suction port 201 can draw in airflow obliquely downwards from the base, allowing the suction port 201 to draw in airflow in the forward direction of the cleaning device 200, thereby improving the efficiency of dust intake.

[0085] For example, air guide walls 207 are provided on both sides of the air intake 201. The air guide walls 207 are set to expand into the dust chamber 205 relative to the air intake 201, so that the dust at both ends of the length of the dust chamber 205 can be gathered in the middle. The air guide walls 207 guide the airflow and are more smoothly drawn into the air intake 201.

[0086] In some embodiments, a scraper 250 may be provided on the bottom side of the base, and the scraper 250 is located on the rear side of the dust chamber 205 along the moving direction of the cleaning device 200 during cleaning. The scraper 250 extends along the width direction of the base.

[0087] Understandably, during the cleaning process of the cleaning device 200, after the area corresponding to the dust chamber 205 passes the surface to be cleaned, the scraper 250 can scrape the surface to be cleaned to ensure that there is no dust or debris residue on the surface to be cleaned.

[0088] For example, the scraping member 250 can be a flexible cleaning member such as an adhesive strip or a brush. The scraping member 250 can extend in a straight line, or it can be arc-shaped; this application embodiment does not specifically limit this.

[0089] Figure 7 Exploded view of the cleaning device 200 provided in the embodiments of this application; Figure 8 This is a schematic diagram of the internal airflow of the cleaning device 200 provided in the embodiments of this application; Figure 9 An exploded view of the components on the second housing 220 of the cleaning device 200 provided in the embodiments of this application.

[0090] Please refer to Figures 7 to 9 In some embodiments, the base may include a first housing 210 and a second housing 220, with the first housing 210 connected above the second housing 220, forming a dust suction channel 203 and a blowing channel 204. A dust-raising chamber 205 is formed on the side of the second housing 220 opposite to the first housing 210.

[0091] It is understandable that both the first housing 210 and the second housing 220 can be injection molded parts, and both are processed and molded separately. In this way, the dust suction channel 203 and the air blowing channel 204 are formed by two independent structures, and the base can be molded separately, which improves processing convenience and reduces costs.

[0092] For example, the edge contours of the first housing 210 and the second housing 220 are matched. When the first housing 210 and the second housing 220 are joined, they can be connected and fixed by ultrasonic welding. Alternatively, when the circumferential edges of the first housing 210 and the second housing 220 are joined, an elastic sealing ring can be provided between them and locked and pressed by a snap fastener or bolt fastener to ensure good sealing performance.

[0093] In some embodiments, in the cleaning direction of the cleaning device 200, an air outlet 202 is provided on the front side of the air blowing channel 204, and the air blowing channel 204 has airflow branches that are diverted from both sides of the dust suction channel 203 and then converged again, so that the air blowing channel 204 is arranged around the dust suction channel 203.

[0094] Understandably, the airflow drawn in by the suction port 201 flows from the front to the rear of the base, while the airflow in the blowing channel 204 flows from the rear of the base, bypassing the suction channel 203, to the front of the base. The blowing channel 204 has two airflow branches, which can make full use of the horizontal space of the base, improve space utilization, and reduce the overall height of the base.

[0095] In some embodiments, the cleaning device 200 may further include a dust collection box 230 disposed within the suction channel 203, through which airflow entering the suction channel 203 from the suction port 201 flows. The dust collection box 230 can be assembled using the space within the suction channel 203, and the airflow entering the suction channel 203 can be filtered by the dust collection box 230, allowing dust and debris to be stored within it.

[0096] For example, a sealing element 240 is provided on the side of the air intake 201 facing the dust collection channel 203, and the sealing element 240 is arranged around the edge of the air intake 201; the circumferential edge of the airflow inlet of the dust collection box 230 abuts against the sealing element 240, thereby ensuring good sealing between the dust collection box and the air intake 201.

[0097] It should be noted that the seal 240 is annular, and its shape matches the shape of the air intake 201. The seal 240 can be made of rubber, silicone, sealing cotton, etc., and this embodiment does not specifically limit its material.

[0099] Please refer to Figure 10 and combined Figure 1 and Figure 2 This application provides a cleaning device, which includes a device body 100 and a cleaning device 200 as described above. The device body 100 and the cleaning device 200 are movably connected. The device body 100 serves as the main structure of the cleaning device and is used by the user to operate and move the cleaning device 200 on the surface to be cleaned. The cleaning device 200 can suck up dust and debris from the surface to be cleaned.

[0100] The main body 100 of the equipment is provided with a fan assembly 120, which is configured to generate negative pressure airflow in the dust suction channel 203 of the cleaning device 200 and positive pressure airflow in the blowing channel 204 of the cleaning device 200.

[0101] Cleaning equipment can achieve both negative pressure suction and dust dispersion functions simultaneously using a single fan, or it can achieve both functions separately using two fans.

[0102] For example, the fan assembly 120 includes a first fan unit 122, the air inlet side of which is connected to the dust collection chamber 111a. The air outlet side of the first fan unit 122 is connected to the exhaust chamber 111b. A single fan unit can simultaneously achieve the functions of negative pressure dust collection and positive pressure dust dispersal.

[0103] For example, the fan assembly 120 includes a first fan unit 122 and a second fan unit (not shown). The air inlet side of the first fan unit 122 is connected to the dust collection chamber 111a, and the air outlet side of the second fan unit is connected to the exhaust chamber 111b. The air outlet side of the first fan unit 122 is connected to the external space, and the air inlet side of the second fan unit is connected to the external space. Thus, the two fan units respectively realize the functions of negative pressure dust collection and positive pressure dust blowing.

[0104] The following is a detailed explanation using the example of the main body of the equipment 100 simultaneously achieving negative pressure dust collection and positive pressure dust dispersal through a single fan unit.

[0105] In one possible implementation, the main body of the device 100 may include a dust collection housing 110, a fan assembly 120 connected to the dust collection housing 110, the dust collection housing 110 enclosing a mutually isolated dust collection chamber 111a and an exhaust chamber 111b, the dust collection chamber 111a being connected to the dust suction channel 203, the air inlet side of the fan assembly 120 being connected to the dust collection chamber 111a, the air outlet side of the fan assembly 120 being connected to the exhaust chamber 111b, and the exhaust chamber 111b being connected to the blowing channel 204.

[0106] It is understandable that the dust collection chamber 111a and the exhaust chamber 111b are two independent spaces. The dust collection housing 110 can be used to form the air inlet and outlet channels of the fan assembly 120, thereby reducing the volume and weight of the main body 100.

[0107] In some embodiments, the cleaning device may further include an adapter 300 connected between the device body 100 and the cleaning device 200, the adapter 300 being configured to allow relative movement between the device body 100 and the cleaning device 200.

[0108] The adapter assembly 300 includes an adapter bracket 310, a suction pipe 320, and a blower pipe 330. Both the suction pipe 320 and the blower pipe 330 are mounted on the adapter bracket 310, with the suction pipe 320 passing through the blower pipe 330. The suction pipe 320 and the blower pipe 330 are nested together, connecting the cleaning device 200 and the main body 100, respectively, thus forming a flow path for suction airflow and a flow path for blower airflow.

[0109] The cleaning device 200 is provided with an air intake 201 and an air outlet 202, and the main body 100 is provided with a dust collection chamber 111a and an exhaust chamber 111b. The two ends of the suction pipe 320 are connected to the air intake 201 and the dust collection chamber 111a respectively, and the two ends of the air outlet 330 are connected to the air outlet 202 and the exhaust chamber 111b respectively.

[0110] Understandably, the suction port 201 of the cleaning device 200 can create negative pressure, allowing the intake airflow to enter the dust collection chamber 111a through the suction pipe 320. Dust and debris in the airflow can be separated from the airflow and collected in the dust collection chamber 111a. The airflow exiting the dust collection chamber 111a is clean air after dust-air separation, which can be recirculated through the exhaust chamber 111b. The airflow in the exhaust chamber 111b enters the cleaning device 200 through the blower pipe 330 and is blown from the blower port 202 of the cleaning device 200 onto the surface to be cleaned, thus achieving the dust-removing function. In this way, airflow circulation is formed, making it easier to clean the dust attached to the surface to be cleaned, improving cleaning efficiency and cleaning effect.

[0111] It should be noted that the vacuum pipe 320 and the blower pipe 330 in the cleaning equipment provided in this application embodiment are nested and connected between the main body 100 and the cleaning device 200, resulting in a more compact structure and smaller space occupation. Both the vacuum pipe 320 and the blower pipe 330 are flexible pipes, so when the cleaning device 200 and the main body 100 move relative to each other, the vacuum pipe 320 and the blower pipe 330 will not interfere with the turning of the cleaning device 200, thus ensuring the flexibility of the cleaning equipment operation.

[0112] Furthermore, the return of clean airflow in the blower pipe 330 utilizes the space between the outer wall of the suction pipe 320 and the inner wall of the blower pipe 330. The airflow blown out by the blower pipe 330 will not affect the airflow in the suction pipe 320. The positive pressure airflow blown out by the blower pipe 330 can be directly blown onto the surface to be cleaned through the blower nozzle 202 of the cleaning device 200, thereby blowing up stubborn dust attached to the ground or deep in the carpet, making it easier to suck the dust into the suction channel 203, resulting in a highly efficient and good cleaning effect.

[0113] The cleaning device provided in this application embodiment can have multiple working modes, including but not limited to ordinary vacuuming mode and dust-spraying mode. When the ordinary vacuuming mode is activated, dust can be sucked in from the suction port 201, while the blowing port 202 does not blow out airflow. When the dust-spraying mode is activated, the suction port 201 generates negative pressure to suck in dust, while the blowing port 202 blows out airflow to disperse the dust, thereby improving the cleaning efficiency.

[0114] Users can switch between different working modes according to specific usage scenarios. For example, when cleaning floors with relatively little dust, the normal vacuuming mode can be used; when cleaning indoor corners or areas where chairs are placed, the dust-dispersing mode can be used. The structure of the fan assembly 120 that enables the switching of the above-mentioned functional modes is described in detail below.

[0115] Please refer to Figure 11 In some embodiments, the fan assembly 120 may include a fan housing 121 and a fan unit, the fan unit being disposed inside the fan housing 121, the fan housing 121 having a first exhaust port 1211 and a second exhaust port 1212, the first exhaust port 1211 being connected to a blowing duct, and the second exhaust port 1212 being connected to the external space of the fan housing 121.

[0116] The cleaning equipment may also include a switching unit 123, which is disposed on the air outlet side of the fan unit inside the fan housing 121. The switching unit 123 is configured to connect the air outlet side of the fan unit to either the first exhaust port 1211 or the second exhaust port 1212.

[0117] Understandably, when the normal vacuuming mode is activated, the switching unit 123 can be switched to connect the air outlet side of the fan unit with the second exhaust port 1212. In this way, the dust drawn in from the suction port 201 by the negative pressure of the fan unit enters the dust collection chamber 111a through the suction pipe 320, and after filtration, it can be discharged into the outside atmosphere. When the dust-spraying mode is activated, the switching unit 123 can be switched to connect the air outlet side of the fan unit with the first exhaust port 1211. In this way, the dust drawn in from the suction port 201 by the negative pressure of the fan unit, after filtration, can enter the blowing pipe 330 through the exhaust chamber 111b, and then enter the cleaning device 200 through the blowing pipe 330. The dust is then blown from the blowing port 202 onto the surface to be cleaned, achieving the dust-spraying function.

[0118] For example, the switching unit 123 may include a motor and a movable plate. The motor can drive the movable plate to rotate, change the airflow direction on the air outlet side of the fan unit, and realize that the air outlet side of the fan unit can be selectively connected to the first exhaust port 1211 and the second exhaust port 1212.

[0119] In some embodiments, the device body 100 further includes a battery assembly 130. The dust collection housing 110, the fan assembly 120, and the battery assembly 130 are coaxially arranged. Thus, along the axial direction of the device body 100, the dust collection housing 110, the fan assembly 120, and the battery assembly 130 can be arranged sequentially to form a portion of the structure, making the device body 100 as a whole form a slender rod-shaped structure.

[0120] It is understood that the fan assembly 120 is located in the middle of the main body 100 of the device. Compared with the prior art where the fan is set at the top, the end of the main body 100 of the device in this embodiment is lighter. The top of the main body 100 is formed into a rod-shaped structure by the battery assembly 130, which makes it easier for the user to hold and operate with less effort.

[0121] This application provides a cleaning device and equipment. The cleaning device includes a base; the base has a dust-collecting chamber, a dust-suction channel, and a blowing channel; the dust-collecting chamber is open downwards towards the base; a suction port and a blowing port are respectively provided on opposite sides of the dust-collecting chamber, the suction port being connected to the dust-suction channel, and the blowing port being connected to the blowing channel. The air outlet of the blowing port is inclined downwards towards the base relative to the horizontal direction, thereby blowing up stubborn dust attached to the ground or deep in the carpet, making it easier to suck the dust into the dust-suction channel, thus achieving a highly efficient and good cleaning effect.

[0122] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
