Technical Field

[0001] This invention belongs to the field of cleaning technology, specifically, it relates to a cleaning device. Background Technology

[0002] In existing cleaning equipment, the airflow generator where the fan is located has a simple structure and a short gas flow path inside the cleaning equipment. This not only results in a high exhaust air velocity and high noise level, but also makes it difficult to provide sufficient space for dust and gas separation due to the short flow path, leading to low cleaning efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning device that solves the problems of high noise and low cleaning efficiency in existing cleaning devices.

[0004] To achieve the above-mentioned objectives, the present invention employs the following technical solution: A cleaning device, comprising: A dust cup assembly that draws in external gas and separates the dust from the gas, with the separated gas being discharged from the dust cup assembly; An airflow generating component, located above and to the side of the dust cup assembly, includes a fan and a fan inlet channel and a fan outlet channel, wherein the inlet end of the fan inlet channel is connected to the outlet end of the dust cup assembly. An exhaust assembly is located on one side of the airflow generating assembly and above the dust cup assembly. The air inlet of the exhaust assembly is connected to the air outlet of the fan outlet channel of the airflow generating assembly, and the gas is discharged through the air outlet of the exhaust assembly. Power supply components are used to provide the electrical energy required for the cleaning equipment to operate; After dust and gas separation, the gas is discharged from the outlet of the dust cup assembly, enters the fan inlet channel upwards, changes its flow direction after entering the fan inlet channel, flows along the axial direction of the fan and flows to the fan outlet channel, changes its flow direction again after entering the fan outlet channel, flows along the axial direction of the fan and in the opposite direction to the flow direction of the fan inlet channel and flows to the exhaust assembly, and finally is discharged upwards through the outlet of the exhaust assembly.

[0005] In some embodiments of this application, the dust cup assembly includes a first suction port, a first separation chamber, and a second separation chamber. The first separation chamber and the second separation chamber are arranged left and right and are connected. The first separation chamber performs a first dust-gas separation on the external gas sucked in through the first suction port. The second separation chamber performs a second dust-gas separation on the gas discharged from the first separation chamber after the first dust-gas separation. The gas after the second dust-gas separation is discharged from the dust cup assembly.

[0006] In some embodiments of this application, the cleaning device further includes: A first filter element is disposed in the first separation chamber. The gas after dust and gas separation in the first separation chamber is filtered by the first filter element, and the filtered gas enters the second separation chamber.

[0007] In some embodiments of this application, the first filter element includes: First filter base; A cylindrical filter section is disposed on the first filter base; A planar filter section is disposed on the first filter base and surrounds the outer periphery of the cylindrical filter section.

[0008] In some embodiments of this application, the cleaning device further includes: A suction nozzle assembly is connected to the dust cup assembly. At one end of the nozzle assembly, which is away from the dust cup assembly, a whole-machine suction port is formed. At the other end of the nozzle assembly, which is opposite to the whole-machine suction port, the nozzle assembly is connected to the first suction port.

[0009] In some embodiments of this application, the airflow generating component includes: Fan casing; A fan housing, which is located inside the fan outer shell, forms the fan inlet channel between the fan outer shell and the fan housing; The fan is installed inside the fan housing, and the fan housing and the fan form the fan outlet channel.

[0010] In some embodiments of this application, the airflow generating component further includes: A diversion duct is provided between the fan inlet channel and the dust cup assembly outlet, and is used to divert the gas discharged from the dust cup assembly to the fan inlet channel.

[0011] In some embodiments of this application, the airflow generating component further includes: The second filter element is disposed in the air inlet channel of the fan and is used to filter the gas in the air inlet channel of the fan.

[0012] In some embodiments of this application, the second filter element includes: The filter main frame is located inside the fan inlet channel; A filter element is disposed on the filter body frame.

[0013] In some embodiments of this application, the fan housing, the fan casing, and the second filter element are all annular structures, the fan housing is sleeved on the outer periphery of the fan casing, and the fan inlet channel and the second filter element are both surrounding the outer periphery of the fan.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are: The cleaning equipment provided by this invention includes an exhaust component above the dust cup assembly, and an airflow generating component on one side of the exhaust component and above the dust cup assembly. The airflow generating component contains a fan inlet channel and a fan outlet channel. The gas, after dust and gas separation, is discharged from the outlet of the dust cup assembly, enters the fan inlet channel upwards, changes direction upon entering, flows along the fan's axial direction, and flows towards the fan outlet channel. Upon entering the fan outlet channel, it changes direction again, flowing along the fan's axial direction and in the opposite direction to the fan inlet channel, and flows towards the exhaust component. Finally, the gas is discharged upwards through the outlet of the exhaust component. This increases the airflow path within the cleaning equipment. The increased flow path provides ample space for dust and other impurities to separate from the airflow, increasing the cleanliness of the gas discharged from the cleaning equipment and improving its cleaning efficiency. Furthermore, the airflow duct effectively absorbs the airflow noise generated by the fan, reducing the exhaust velocity in the exhaust chamber and thus lowering the overall noise level of the cleaning equipment.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Figures 1 to 13 An embodiment of the cleaning device proposed in this invention is shown. The following is in conjunction with... Figures 1 to 13 This describes the cleaning device of this embodiment.

[0020] See Figures 1 to 9As shown, the cleaning device in this embodiment includes a nozzle assembly 1, a dust cup assembly 2, an airflow generating assembly 3, an exhaust assembly 4, and a handle assembly 5.

[0021] The dust cup assembly 2 includes a dust cup shell 20 and a dust-gas separation chamber disposed within the dust cup shell 20. A first suction port 2021 communicating with the separation chamber is formed on the dust cup shell 20. The separation chamber is capable of separating dust and gas from the gas entering the dust cup assembly 2 from the first suction port 2021.

[0022] The nozzle assembly 1 is installed on the dust cup housing 20. One end of the nozzle assembly away from the dust cup housing 20 forms the whole machine suction port 11, and the other end opposite to the whole machine suction port 11 is connected to the first suction port 2021 on the dust cup housing 20.

[0023] The exhaust assembly 4 is located above the dust cup assembly 2. The exhaust assembly 4 includes an exhaust housing 41 and an exhaust chamber disposed within the exhaust housing 41. The exhaust chamber and the separation chamber of the dust cup assembly 2 are isolated from each other in the air duct.

[0024] The airflow generating component 3 is located on one side of the exhaust component 4, and is positioned above and to the side of the dust cup component 2. The airflow generating component 3 includes a fan housing 31 and a fan cavity located inside the fan housing 31. The fan cavity includes a connected fan inlet channel and a fan outlet channel, and a fan 37 is installed within the fan outlet channel. The fan 37 is arranged laterally, and the axial direction of the fan cavity is parallel to the axial direction of the fan 37. The axial direction of the fan cavity forms an angle greater than 0° with the axial direction of the dust cup component 2 (i.e., the axial direction of the dust-gas separation chamber) and with the axial direction of the exhaust component 4 (i.e., the axial direction of the exhaust cavity). The fan inlet channel includes an inlet end and an outlet end, and the fan outlet channel includes an inlet end and an outlet end. The inlet end of the fan inlet channel and the outlet end of the fan outlet channel are both located at the end of the fan 37 closest to the exhaust assembly 4, while the outlet end of the fan inlet channel and the inlet end of the fan outlet channel are both located at the other end of the fan 37 furthest from the exhaust assembly 4. Furthermore, the inlet end of the fan inlet channel is connected to the outlet of the separation chamber of the dust cup assembly 2, and the outlet end of the fan outlet channel is connected to the inlet of the exhaust chamber of the exhaust assembly 4.

[0025] In some other embodiments, the axial direction of the fan chamber is perpendicular to the axial direction of the dust cup assembly 2 (i.e., the axial direction of the dust-gas separation chamber) and the axial direction of the exhaust assembly 4 (i.e., the axial direction of the exhaust chamber), forming an angle of 90°.

[0026] See Figure 5The airflow direction is as follows: When the cleaning equipment is gripped by the handle assembly 5, under the negative pressure generated by the fan 37 in the airflow generating assembly 3, the gas containing dust and other impurities enters the separation chamber of the dust cup assembly 2 through the whole machine suction port 11 of the suction nozzle assembly 1 and the first suction port 2021 of the dust cup assembly 2 for dust-gas separation. The separated dust and other impurities are stored in the dust cup shell 20. The separated clean gas flows upward towards the fan chamber, enters the fan inlet channel through the inlet end of the fan inlet channel, and then changes its flow direction, flowing to the left along the axial direction of the fan 37, reaching the outlet end of the fan inlet channel and the inlet end of the fan outlet channel; then the gas changes its flow direction again, flowing to the right along the axial direction of the fan 37, that is, in the opposite direction to the airflow in the fan inlet channel, flowing in the fan outlet channel, and then flowing to the exhaust chamber of the exhaust assembly 4 through the outlet end of the fan outlet channel, and finally being discharged from the exhaust chamber to the outside of the cleaning equipment.

[0027] The clean gas, separated in the separation chamber, flows through the fan chamber in the airflow generating assembly 3 and the exhaust chamber in the exhaust assembly 4. In particular, it flows through the fan inlet and outlet channels arranged along the axial direction of the fan 37 in the airflow generating assembly 3, increasing the flow path of the airflow within the cleaning equipment. This increased flow path provides ample space for the separation of dust and other impurities from the airflow, improving the cleanliness of the gas discharged from the cleaning equipment and enhancing its cleaning efficiency. Furthermore, the air ducts effectively absorb the airflow noise generated by the fan 37, reducing the exhaust velocity in the exhaust chamber and thus lowering the overall noise level of the cleaning equipment.

[0028] In some other embodiments, the cleaning device does not have a handle assembly 5, and the cleaning device is assembled into other devices for use.

[0029] See Figure 6 Exploded view of the dust cup assembly and Figure 7 As shown in the partially exploded structural diagram of the dust cup assembly, in some embodiments of the present invention, the dust cup housing 20 of the dust cup assembly 20 includes a bottom cover 201, a side wall 202, and a top cover 204. The side wall 202 has a barrel-like structure, and the bottom cover 201 and the side wall 202 are detachably and sealed together. The top cover 204 and the side wall 202 are also detachably and sealed together. In some embodiments, the detachable assembly structure adopts a slot and hook structure; in other embodiments, the detachable assembly structure adopts a screw and stud structure; in still other embodiments, the detachable assembly structure adopts a structure in which both slots / hooks and screws / studs are engaged.

[0030] The dust cup housing 20 has a first separation chamber 21 and a second separation chamber 23 inside. The first separation chamber 21 is close to and communicates with the suction nozzle assembly 1, and is approximately cylindrical in shape, used for the first dust-gas separation of the airflow entering the dust cup housing 20. The second separation chamber 23 communicates with the first separation chamber 21 and is used for the second dust-gas separation of the airflow discharged from the first separation chamber 21.

[0031] The first separation chamber 21 and the second separation chamber 23 are arranged in a left-right configuration inside the dust cup housing 20. The airflow exits from the first separation chamber 21, changes direction, and then flows into the second separation chamber 23, thus increasing the variation in the airflow direction within the dust cup housing. This change in airflow direction reduces gas flow velocity and noise, enhances dust-air separation, improves the cleanliness of the gas discharged from the cleaning equipment, and ultimately increases the cleaning efficiency of the equipment.

[0032] Specifically, in this embodiment, the dust cup assembly 2 further includes a top plate 203, which is disposed on the inner wall of the side wall 202 near the dust cup top cover 204. The outer periphery of the top plate 203 is sealed to the inner wall of the side wall 202, and a top plate air cavity 2032 is formed between the top plate 203 and the dust cup top cover 204. The bottom cover 201, the top plate 203, and part of the side wall 202 define a first separation cavity 21; the bottom cover 201, the top plate 203, and another part of the side wall 202 define a second separation cavity 22.

[0033] A first intake port 2021 is provided on the side wall 202 forming the first separation chamber 21, near the top plate 203. A first exhaust port 2031 is provided on the top plate 203, opposite the first separation chamber 21. In some other embodiments, the first exhaust port 2031 is positioned towards the center of the first separation chamber 21. The first intake port 2021 is tangent to the inner wall of the side wall 202, so that the airflow drawn in from the nozzle assembly 1 enters the first separation chamber 21 along the first intake port 2021, rotates downward along the inner wall of the first separation chamber 21, and generates centrifugal force. The airflow uses centrifugal force to separate dust and gas within the first separation chamber 21. The separated dust and other impurities fall onto the bottom cover 201 and remain in the first separation chamber 21. The separated gas flows out of the first separation chamber 21 from the first exhaust port 2031 and then enters the top plate air chamber 2032.

[0034] When it is necessary to clean the dust and other impurities remaining in the first separation chamber 21, simply remove the bottom cover 201 from the side wall 202 and pour out the dust and other impurities.

[0035] In other embodiments, see Figure 5 and Figure 6A first filter element 22 is provided in the first separation chamber 21, covering the first outlet 2031. The gas after dust-gas separation in the first separation chamber 21 first passes through the first filter element 22 for further filtration and dust removal. The filtered impurities remain on the outer surface of the first filter element and / or fall onto the bottom cover 201. The filtered clean gas is discharged from the first outlet 2031. By using the first filter element 22 to filter the gas, the air cleaning effect is improved, and damage to components such as the fan 37 in the subsequent airflow generation assembly is prevented, thus extending the overall service life of the cleaning equipment.

[0036] In some embodiments, such as Figure 5 and Figure 6 As shown, the first filter element 22 includes a first filter base 221, a cylindrical filter section 223 disposed on the first filter base 221, and a planar filter section 222 disposed on the first filter base and surrounding the outer periphery of the cylindrical filter section 223. The outer diameter of the cylindrical filter section 223 is smaller than the outer diameter of the first filter base 221. The cylindrical filter section 223 extends upward from the first filter base 221, and its upper end, away from the first filter base 221, connects with the first discharge outlet 2031. The bottom of the first filter base 221 is open. An airflow space is formed between the first filter base 221 and the inner wall of the first separation chamber 21 and the inner surface of the bottom cover 201. An airflow space is also formed between the cylindrical filter section 223 and the inner wall of the first separation chamber 21. The gas separated from the dust in the first separation chamber 21 enters the interior of the cylindrical filter section 223 through the planar filter section 222 and the cylindrical filter section 223, and then continues to flow upward to the first discharge outlet 2031 and is discharged.

[0037] In some embodiments, the planar filter section 222 is a filter screen disposed on the first filter base 221; in other embodiments, the planar filter section 222 is a plurality of air holes formed on the first filter base 221. In some embodiments, the cylindrical filter section 223 is a filter plate with a plurality of air holes disposed on the first filter base 221; in other embodiments, the cylindrical filter section 223 includes a filter frame disposed on the first filter base 221 and a cylindrical filter screen disposed on the filter frame.

[0038] In other embodiments, see Figure 15 A cross-sectional view of another embodiment of the cleaning device proposed by the present invention is shown. Figure 16 The schematic diagram of a partial structure of the dust cup assembly in this embodiment is shown. Figure 17The schematic diagram of the first filter element shown illustrates that the first filter element 22 includes a first filter base 224 and a cylindrical filter portion 225 disposed on the first filter base 224. The outer diameter of the cylindrical filter portion 225 is smaller than the outer diameter of the first filter base 224. The cylindrical filter portion 225 extends upward from the first filter base 224, and its upper end, away from the first filter base 224, connects with the first outlet 2031. The first filter base 224 has a plurality of notches 2241 formed thereon, and a planar filter portion 2242 is also disposed on the first filter base 224 surrounding the outer periphery of the cylindrical filter portion 225. In some embodiments, two notches 2241 are symmetrically formed on the first filter base 224, such as... Figure 17 As shown. In some other embodiments, three or four notches 2241 may be formed on the first filter base 224. In some embodiments, multiple notches are evenly distributed on the first filter base 224 to improve the uniformity of airflow. The outer periphery of the first filter base 224 is adapted to the shape of the inner wall of the first separation cavity 21. For example, in some embodiments, the inner wall of the first separation cavity 21 is cylindrical, and the outer periphery of the first filter base 224 is circular. The outer periphery of the first filter base 221 is close to but does not contact the inner wall of the first separation cavity 21, or the first filter base 221 abuts against the inner wall of the first separation cavity 21. An airflow space is formed between the bottom surface of the first filter base 221 and the inner surface of the bottom cover 201, and an airflow space is also formed between the cylindrical filter part 225 and the inner wall of the first separation cavity 21. The airflow drawn in from the nozzle assembly 1 enters the first separation chamber 21 through the first intake port 2021. It then rotates downwards along the inner wall of the first separation chamber 21, generating centrifugal force. The airflow rotates downwards along the notch 2241 on the first filter base 224 to the bottom of the first separation chamber 21, where dust and other impurities remain on the bottom cover 201. The clean gas after dust-air separation passes through the planar filter section 2242, then through the cylindrical filter section 225 and continues to flow upwards, finally exiting from the first discharge port 2031. The first filter element 22 further filters the gas after dust-air separation, retaining as much dust and other impurities as possible within the first separation chamber 21, improving air cleaning efficiency and preventing damage to components such as the fan 37 in the subsequent airflow generation assembly. Furthermore, since the outer periphery of the first filter base 224, except for the notch 2241, is close to and / or abuts against the inner wall of the first separation chamber 21, the separated dust can be compressed and confined between the first filter base 224 and the bottom cover 201, preventing dust from scattering throughout the first separation chamber 21 or even being carried out of the first separation chamber 21 by the airflow. This effectively avoids the problem of dust scattering and / or being carried out, thus affecting the dust-air separation effect of the first separation chamber 21 and reducing cleaning efficiency. It also effectively reduces the frequency of cleaning the dust cup assembly 2 due to dust scattering in the first separation chamber 21, further improving cleaning efficiency.

[0039] In some embodiments, the planar filter section 2242 is a filter screen disposed on the first filter base 224; in other embodiments, the planar filter section 2242 is a plurality of air holes formed on the first filter base 224. In some embodiments, the cylindrical filter section 225 is a filter plate with a plurality of air holes disposed on the first filter base 224; in other embodiments, the cylindrical filter section 225 includes a filter frame disposed on the first filter base 224 and a cylindrical filter screen disposed on the filter frame.

[0040] In other embodiments, see Figure 18 A cross-sectional view of another embodiment of the cleaning device proposed by the present invention is shown. Figure 19 The schematic diagram of the first filter element shown illustrates that the first filter element 22 includes a filter cylinder 226, which has an open structure at both the bottom and top. An airflow space is formed between its lower opening and the bottom cover 201, and its upper opening connects to the first outlet 2031. An airflow space is also formed between the filter cylinder 226 and the inner wall of the first separation chamber 21. A first filter layer 227 and a second filter layer 228 are disposed within the internal cavity of the filter cylinder 226. The first filter layer 227 is located at the lower layer, closer to the bottom opening of the filter cylinder 226; the second filter layer 228 is located at the upper layer, closer to the top opening of the filter cylinder 226. Airflow drawn in from the nozzle assembly 1 enters the first separation chamber 21 through the first intake port 2021 and rotates downwards along the inner wall of the first separation chamber 21, generating centrifugal force. The airflow uses centrifugal force to separate dust and air within the first separation chamber 21. The separated dust and other impurities fall onto the bottom cover 201 and remain within the first separation chamber 21. The clean gas after dust and gas separation flows upward and is filtered through the first filter section 227. The filtered dust and other impurities fall downward into the space between the bottom cover 201 and the first filter section 227. The filtered clean gas continues to flow upward and is filtered again through the second filter section 228. The filtered clean gas continues to flow upward and is finally discharged from the first outlet 2031.

[0041] By utilizing the first filter element 22 with two layers of filtration, the gas after dust-gas separation can be further filtered twice, retaining as much dust and other impurities as possible within the first separation chamber 21. This improves the air cleaning effect and prevents damage to components such as the fan 37 in the subsequent airflow generation assembly. The first layer of filtration 227 located at the bottom compresses and confines the separated dust and other impurities as much as possible between the bottom cover 201 and the first layer of filtration 227, preventing dust from scattering throughout the first separation chamber 21 or being carried out of it by the airflow. This effectively avoids the problem of dust scattering and / or being carried out, which affects the dust-gas separation effect of the first separation chamber 21 and reduces cleaning efficiency. It also effectively reduces the frequency of cleaning the dust cup assembly 2 due to dust scattering within the first separation chamber 21, further improving cleaning efficiency.

[0042] In some embodiments, such as Figure 18 As shown, the first-layer filter section 227 has an overall inverted V-shaped structure, with the opening of the inverted V facing the bottom of the filter cylinder 226, and the outer periphery of the inverted V-shaped structure abutting against the inner wall of the filter cylinder 226. The second-layer filter section 228 has an overall V-shaped structure, with the opening of the V facing the top of the filter cylinder 226, and the outer periphery of the V-shaped structure abutting against the inner wall of the filter cylinder 226. By setting the first-layer filter section 227 and the second-layer filter section 228 into V-shaped structures, the filtration area can be increased, and the airflow filtration efficiency can be improved.

[0043] In some embodiments, the top end of the second filter layer 228 and the first outlet 2031 are vertically spaced by a certain distance L1. By setting a certain distance between the top end of the second filter layer 228 and the first outlet 2031 in the vertical direction, a larger airflow space can be formed between the second filter layer 228 and the first outlet 2031, which slows down the outflow speed of the air from the first outlet 2031, reduces airflow noise, and prevents dust from being carried out of the first separation chamber 21 due to excessively fast flow, thereby further improving the filtration and cleaning effect.

[0044] In some embodiments, to balance the smoothness of airflow and the dust filtration effect, the V-angle A of the first filter layer 227 is in the range of 90-135°. Correspondingly, the V-angle B of the second filter layer 228 is also in the range of 90-135°.

[0045] In some embodiments, such as Figure 18 As shown, the filter body portions of the first filter section 227 and the second filter section 228 are planar. That is, in Figure 18 In the sectional view, the outlines of the two inclined sides of the two-layer filter section of the V-shaped structure are straight lines.

[0046] In some other embodiments, the filter body portions of the first filter layer 227 and the second filter layer 228 are spherical. That is, if... Figure 18 As shown in the cross-sectional view, the two inclined sides of the V-shaped two-layer filter section have curved outlines. Using a spherical filter section provides a larger filtration area and facilitates the cleaning of dust and other impurities.

[0047] In some embodiments, the first layer filter 227 is a filter plate with multiple air holes, and the second layer filter 228 is a filter plate with multiple air holes; in other embodiments, the first layer filter 227 includes a filter frame and a filter screen disposed on the filter frame, and the second layer filter 228 includes a filter frame and a filter screen disposed on the filter frame.

[0048] See also Figure 5 , Figure 6 and Figure 7 As shown, the second separation chamber 23 is located on one side of the first separation chamber 21, and is the side away from the nozzle assembly 1. Figure 5 In the cross-sectional view, the nozzle assembly 1 is located to the right of the first separation chamber 21, and the second separation chamber 23 is located to the left of the first separation chamber 21.

[0049] To ensure smooth and stable airflow into the second separation chamber 23 for dust-air separation, in some embodiments, the dust cup assembly 2 further includes a second suction section 241. The second suction section 241 includes a second suction inlet 2411 and a second guide plate 2412. The second suction inlet 2411 is formed on the top plate 203, and the second guide plate 2412 extends upward along a portion of the opening edge of the second suction inlet 2411 to the bottom surface of the dust cup top cover 204, abutting against the bottom surface of the dust cup top cover 204. The second guide plate 2412 includes a first guide section 24121 that matches a portion of the opening edge of the second suction inlet 2411 and a second guide section 24122 extending towards the first discharge outlet 2031. An airflow inlet 24123 is formed between the free end of the first guide section 24121 and the free end of the second guide section 24122, and the airflow inlet 24123 faces the first discharge outlet 2031.

[0050] In some embodiments, the dust cup assembly 2 further includes a second separation section 242 located within the second separation chamber 23 and an airflow outlet pipe 244 partially located within the second separation section 242. The second separation section 242 extends from the second suction port 2411 into the second separation chamber 23 to form a cylindrical body, with a dust discharge port 243 formed at the bottom of the cylindrical body. The dust discharge port 243 is vertically spaced at a distance L2 from the bottom of the second separation chamber 23. The airflow outlet pipe 244 partially extends into the second separation section 242 and partially extends upward to the dust cup top cover 204, and connects with the second discharge port 2041 provided on the dust cup top cover 204. The bottom end of the portion of the airflow outlet pipe 244 extending into the second separation section 242 is vertically spaced at a distance L3 from the dust discharge port 243.

[0051] The airflow exiting from the first outlet 2031 enters the top plate air chamber 2032 and continues to flow towards the airflow inlet 24123. Guided by the second guide plate 2412, the airflow enters the second separation section 242 tangentially along its inner wall, rotates downwards along the inner wall, and generates centrifugal force for a second dust-air separation. The dust and other impurities after the second dust-air separation fall from the dust outlet 243 into the accommodating space of the second separation chamber 23 below the second separation section 242, while the separated clean gas flows upwards to the airflow outlet pipe 244, flows upwards along the airflow outlet pipe 244, and finally exits from the second outlet 2041.

[0052] When it is necessary to clean the dust and other impurities remaining in the second separation chamber 23, simply remove the bottom cover 201 from the side wall 202 and pour out the dust and other impurities.

[0053] By setting a second separation section 242 in the second separation chamber 23, and setting an airflow outlet pipe 244 in the second separation section 242, and setting a dust discharge port 243 with a certain distance from the bottom of the second separation chamber 23 to form a certain accommodating space between the second separation section 242 and the second separation chamber 23, and setting the bottom end of the airflow outlet pipe 244 with a certain distance from the dust discharge port 243 in the vertical direction, secondary dust and gas separation is performed using the second separation section 242. The separated clean gas is discharged through the airflow outlet pipe 244, and the separated dust and other impurities are stored in the accommodating space below the second separation section 242. This can reduce the airflow in the area where dust and other impurities are stored in the second separation chamber 23, reduce the swirling of dust and other impurities, prevent dust and other impurities from being carried out by the discharged airflow, and improve the dust and gas separation effect.

[0054] In some embodiments, the inner diameter of the cylinder of the second separation section 242 gradually narrows from top to bottom, forming an inverted frustum shape. By setting the inner diameter of the second separation section 242 to gradually narrow from top to bottom, the airflow entering the second separation section 242 will accelerate and spiral down within the second separation section 242, improving the speed and efficiency of dust and gas separation.

[0055] In some embodiments, the number of second separation chambers 23 may be one or more. Figure 6 In the illustrated embodiment, there are four second separation chambers 23. When multiple second separation chambers 23 are provided, each separation chamber is independent of the others, and each separation chamber 23 is provided with a second suction section 241, a second separation section 242, and an airflow outlet pipe 244.

[0056] In some embodiments, see Figure 5 and Figure 6 As shown, an upwardly protruding protrusion 2042 is formed on the dust cup top cover 204 at a position corresponding to the first outlet 2031. By forming the protrusion 2042 on the dust cup top cover 204, the inner wall of the protrusion 2042 (in...) Figure 5 In the middle, the inner wall (referring to the lower surface of the protrusion 2042) is far away from the first outlet 2031, thereby creating a larger airflow space between the first outlet 2031 and the protrusion 2042, which facilitates the smooth discharge of airflow from the first outlet 2031 into the top plate air cavity 2032.

[0057] See Figure 8 Partial shell assembly structure diagram, Figure 9 A partial cross-sectional view of the outer shell, Figure 10 An exploded view of the airflow generating components, combined with... Figures 1 to 7 The structure of the airflow generating component 3 will be described in detail.

[0058] The airflow generating assembly 3 includes a fan housing 31, an air duct 32, a fan housing 33, and a fan 37. The fan housing 33 is located inside the fan housing 31, forming a fan inlet channel 34 between the fan housing 31 and the fan housing 33. The fan 37 is disposed inside the fan housing 33, forming a fan outlet channel 36 between the fan housing 33 and the fan 37. The fan inlet channel 34 and the fan outlet channel 36 are interconnected. The fan inlet channel 34 is also connected to the second separation chamber 23 of the dust cup assembly 2, and the fan outlet channel 36 is connected to the exhaust chamber of the exhaust assembly 4. The fan housing 31 has an annular structure, and the fan housing 33 also has an annular structure. The fan housing 31 is fitted around the outer periphery of the fan 33; therefore, the fan inlet channel 34 surrounds the outer periphery of the fan 37. By surrounding the fan inlet channel around the fan, the uniformity of airflow can be increased, and it is easier to achieve a compact and miniaturized design of the overall structure of the airflow generating assembly.

[0059] In some embodiments, such as Figure 10 As shown, a fan inlet 331 is provided at the left end of the fan housing 33, and the air outlet of the fan inlet channel 34 and the air inlet of the fan outlet channel 36 are connected through the fan inlet 331.

[0060] The air inlet end of the fan inlet channel 34 is located at the end near the dust cup assembly 2 and the exhaust assembly 4. Specifically, in Figure 5 In the structure shown, the air inlet end of the fan inlet channel 34 is located at the right end of the fan housing 31. Furthermore, the air inlet end of the fan inlet channel 34 is close to the second outlet 2041 of the dust cup assembly 2. The air outlet end of the fan inlet channel 34 is located at the end furthest from the dust cup assembly 2 and the exhaust assembly 4. Specifically, in... Figure 5 In the structure shown, the outlet end of the fan inlet channel 34 is located at the left end of the fan housing 31. The inlet end of the fan outlet channel 36 is close to the outlet end of the fan inlet channel 34, while the outlet end of the fan outlet channel 36 is close to the exhaust assembly 4. Specifically, in Figure 5 In the structure shown, the air inlet of the fan outlet channel 36 is located at the left end, and the air outlet of the fan outlet channel 36 is located at the right end.

[0061] A diversion duct 32 is disposed between the fan inlet channel 34 and the second outlet 2041 of the dust cup assembly 2, and is used to guide the airflow discharged from the second outlet 2041 to the fan inlet channel 34. The diversion duct extends from the outer periphery of the second outlet 2041 toward the fan inlet channel 34.

[0062] In some embodiments, the air duct 32 guides the airflow discharged from the second outlet 2041 into the fan inlet channel 34 along the tangential direction of the inner wall of the fan housing 31, so that the airflow generates centrifugal force in the fan inlet channel 34, thereby improving the dust-air separation effect.

[0063] In some embodiments, the air duct 32 is independent of and sealed to the fan housing 31. In some embodiments, such as Figure 9 As shown, the air duct 32 and the fan housing 31 are integrally formed.

[0064] In some embodiments, a second filter element 35 is provided in the fan inlet channel 34 to filter and remove dust from the airflow entering the fan inlet channel 34. The filtered dust and other impurities remain on the second filter element 35, and the filtered clean air enters the fan outlet channel 36. By providing a second filter element 35 in the fan inlet channel 34 to further filter the air after dust separation by the dust cup assembly, the air cleaning effect is improved. It also prevents dusty air from entering the fan outlet channel 36 and damaging the fan 37, thus extending the service life of the entire cleaning equipment.

[0065] In some embodiments, see Figure 10 As shown, the second filter element 35 includes a filter body frame 352, on which a filter body is disposed. In some embodiments, the filter body is a flexible filter screen; in other embodiments, the filter body is a porous filter material. Adapted to the annular structure of the fan housing 31 and the fan housing 33, the filter body frame 352 is also annular and surrounds the outer periphery of the fan housing 33. Therefore, the filter body placed on the filter body frame 352 also surrounds the outer periphery of the fan housing 33, thereby effectively filtering the airflow entering the fan inlet and improving the filtration effect.

[0066] In some embodiments, see Figure 8 , Figure 9 and Figure 10 As shown, the fan housing 31 includes a fan housing side wall 311, a front cover 312, and a rear cover 313. The fan housing side wall 311 has an annular structure. The front cover 312 is located at the end of the fan housing side wall 311 away from the exhaust assembly 4, and the rear cover 313 is located at the end of the fan housing side wall 311 close to the exhaust assembly 4. The front cover 312 is connected to the fan housing side wall 311, and an annular opening 314 is formed between the ends of the front cover 312 and the fan housing side wall 311. The rear cover 313 is connected to the fan housing side wall 311, and a rear cover opening 3131 is formed on the rear cover 313. This rear cover opening 3131 serves as the final airflow outlet of the airflow generating assembly, corresponding to the fan outlet on the fan housing 33, and communicating with the fan outlet channel 36. The second filter element 35 also includes an external end 351, which is located at one end of the filter body frame 352, specifically at the end of the filter body frame 352 near the front cover 312. The external end 351 is connected to the filter body frame 352. In the assembled structure, the filter body frame 352 and the filter element thereon are placed in the fan inlet channel 34 between the fan housing 31 and the fan housing 33. The external end 351 is sealed to the annular opening 314, and at least part of the external end 351 is exposed. By operating the external end 351, the filter body frame 352 and the filter element thereon can be pulled out of the fan inlet channel 34, or the filter body frame 352 and the filter element thereon can be inserted into the fan inlet channel 34. After pulling the filter body frame 352 and the filter element thereon out of the fan inlet channel 34, dust and other impurities on the filter element can be cleaned, the filter element can be washed, or the filter element can be replaced.

[0067] In some embodiments, the filter body frame 352 and the filter element thereon are pulled apart and retracted from the fan housing 31 via a sliding structure, improving assembly and disassembly efficiency and convenience. In some embodiments, the sliding structure is a combination of a slide rail and a slide groove. In some embodiments, the sliding structure is a combination of a guide wheel and a guide rail.

[0068] In some other embodiments, the second filter element 35 is filter material that fills the entire fan inlet channel 34.

[0069] In some other embodiments, a display module is provided on the fan housing 31. The display module is connected to the control module of the cleaning equipment and displays information or indications such as the power level, working mode, fan speed, and fault reminders of the cleaning equipment. In some embodiments, the display module is located on the front cover 312 of the fan housing 31.

[0070] In some embodiments, the fan housing 31, the fan housing 33, and the fan 37 are assembled using the following structure: The rear end of the fan 37 is mounted to the rear end cover 313 constituting the fan housing 31 via the fan base 38, and the front end of the fan 37 is mounted to the fan housing 33. The rear end of the fan housing 33 is mounted to the rear end cover 313, and its front end is mounted to the front end cover 312 constituting the fan housing 31 via the connector 39. Thus, the fan 37 is laterally mounted within the fan housing with a simple structure, and the overall structure of the airflow generating component is compact and miniaturized.

[0071] See Figure 11 Exploded view of the air outlet component Figure 12 Cross-sectional view of the air outlet inner shell and Figure 13 A bottom view of the air outlet inner shell, combined with Figures 1 to 10 The structure of the exhaust component 4 will be described in detail.

[0072] The exhaust assembly 4 includes an exhaust housing 41, an exhaust inner housing 42, and an exhaust top cover 47. The exhaust inner housing 42 is located within the space enclosed by the exhaust housing 41 and the exhaust top cover 47. The exhaust housing 41, the exhaust inner housing 42, and the exhaust top cover 47 together define the exhaust chamber of the exhaust assembly 4.

[0073] In some embodiments, the exhaust housing 41 serves as the exhaust housing of the exhaust assembly 4; in some embodiments, the exhaust housing 41 and the exhaust inner housing 42 together serve as the exhaust housing of the exhaust assembly 4.

[0074] The exhaust housing 41 has an overall annular structure. Its bottom end is sealed to the dust cup housing 20 in the dust cup assembly 2, and its top end is sealed to the exhaust top cover 47. The end of the exhaust housing 41 near the airflow generating assembly 3 is connected to the fan housing 31. The exhaust housing 41 has an exhaust housing opening on the side near the fan housing 31.

[0075] The exhaust inner shell 42 has an overall annular structure and is located above the dust cup top cover 204 in the dust cup assembly 2, with its bottom end connected to the dust cup top cover 204. An exhaust inlet 421 is provided at one end of the exhaust inner shell 42 near the airflow generating assembly 3. The exhaust inlet 421 serves as the air inlet of the exhaust chamber of the exhaust assembly 4 and is connected to the air outlet end of the fan outlet channel 36 of the airflow generating assembly 3 through the exhaust outer shell opening. In some embodiments, the exhaust inlet 421 is connected to the rear cover opening 3131.

[0076] An exhaust partition plate 43 is provided inside the exhaust inner shell 42. The exhaust partition plate 43 has a rotating air duct outlet 431, thereby dividing the internal cavity of the exhaust inner shell 42 into two connected cavities, upper and lower. A rotating air outlet device 44 is provided in the lower cavity of the exhaust partition plate 43, and a third filter element 45 is provided in the upper cavity of the exhaust partition plate 43.

[0077] In some embodiments, the lower cavity of the exhaust partition plate 43 is higher than the upper cavity, so as to provide a longer rotating air outlet duct using the lower cavity. In some embodiments, the rotating air outlet 431 is located in the middle of the exhaust partition plate 43 to achieve uniform airflow within the exhaust cavity.

[0078] The rotating air outlet device 44 includes a rotating air duct shell 441, which defines a rotating air duct 442. The air inlet of the rotating air duct 442 is connected to the air exhaust inlet 421, and the air outlet of the rotating air duct 442 is connected to the air outlet 431.

[0079] The third filter element 45 is an annular body surrounding the outer periphery of the rotary air duct outlet 431. The third filter element 45 extends upward from the upper surface of the exhaust partition plate 43 to near the exhaust top cover 47. A certain space is left between the outer edge of the third filter element 45 and the inner wall of the exhaust inner shell 42. The upper surface of the exhaust partition plate 43, the third filter element 45, the inner wall of the exhaust inner shell 42, and the exhaust top cover 47 together define the exhaust air duct 46. The air inlet of the exhaust air duct 46 is connected to the rotary air duct 442 through the rotary air duct outlet 431, and the air outlet of the exhaust air duct 46 is connected to the top cover exhaust port 473 on the exhaust top cover 47.

[0080] The airflow discharged from the airflow generating component 3 enters the rotating air duct 442 through the exhaust inlet 421, flows out of the rotating air outlet 431 of the rotating air duct, exits the rotating air outlet 44, and then flows to the third filter element 45. The clean air, after being further filtered by the third filter element 45, enters the exhaust air duct 46 and continues to flow upward, finally being discharged from the top cover exhaust outlet 473. By setting up the rotating air duct 442 and the exhaust air duct 46, the length of the exhaust air duct located at the rear end of the fan 37 is increased, thereby extending the overall airflow exhaust air duct length inside the cleaning equipment, further reducing the exhaust air velocity and exhaust noise. By setting up the third filter element 45, the air is filtered again, improving the cleanliness of the exhaust air and further improving the dust collection effect of the cleaning equipment.

[0081] In some embodiments, see Figure 12 and Figure 13 As shown, the rotating air duct shell 441 includes an inner ring air duct shell 4411, which is a non-closed annular structure with an inner ring air duct inlet 4412. The inner ring air duct shell 4411 is located in the middle of the lower cavity and forms an annular air duct with the shell of the exhaust inner shell 42 that forms the lower cavity. The bottom end of the inner ring air duct shell 4411 and the inner ring air duct inlet 4412 are away from the exhaust air intake 421 on the exhaust inner shell 42. In some embodiments, the inner ring air duct inlet 4412 faces away from the exhaust air intake 421, thereby dividing the annular air duct from the exhaust air intake 421 to the inner ring air duct inlet 4412 into two paths, namely a first diversion air duct 4421 and a second diversion air duct 4422.

[0082] See Figure 13 As indicated by the arrow, the airflow flowing in from the exhaust inlet 421 is split into two: one flows along the first branching duct 4421 to the inner ring duct inlet 4412, and the other flows along the second branching duct 4422 to the inner ring duct inlet 4412. The two airflows converge within the cavity of the inner ring duct shell 4411 and then exit from the rotating duct outlet 431. By positioning the inner ring duct inlet 4412 away from the exhaust inlet 421 on the exhaust inner shell 42, the annular duct between the exhaust inlet 421 and the inner ring duct inlet 4412 is divided into two paths, achieving dual exhaust to the inner ring duct shell 4411, increasing the exhaust air volume and improving the overall airflow of the unit.

[0083] In some embodiments, see Figure 13As shown, a first guide shell 4413 is provided in the first diversion duct 4421, near the air inlet 4412 of the inner ring duct, and a second guide shell 4414 is provided in the second diversion duct 4422, near the air inlet 4412 of the inner ring duct. One end of the first guide shell 4413 is connected to the exhaust inner shell 42, and the other end is near the air inlet 4412 of the inner ring duct; one end of the second guide shell 4414 is connected to the exhaust inner shell 42, and the other end is near the air inlet 4412 of the inner ring duct. By providing the first guide shell 4413 and the second guide shell 4414, the airflow in the diversion channel can be smoothly guided into the cavity of the inner ring duct shell 4411.

[0084] In some embodiments, both the first flow guide shell 4413 and the second flow guide shell 4414 are arc-shaped shells.

[0085] In some embodiments, see Figure 14 The bottom view shown is of another embodiment of the exhaust inner shell. The rotating air duct shell 441 includes a spiral air duct shell 4415. The outer end of the spiral air duct shell 4415 is sealed to the inner wall of the exhaust inner shell 42 near the exhaust air inlet 421. A spiral air duct inlet 4416 is formed at the inner end of the spiral air duct shell 4415. The bottom end of the spiral air duct shell 4415 is connected to the dust cup top cover 204 and extends upward from the dust cup top cover 204 until it abuts against the lower bottom surface of the exhaust partition plate 43 and connects with the rotating air duct outlet 431. A spiral rotating air duct 442 is formed between the spiral air duct shell 4415 and the shell of the exhaust inner shell 42 forming the lower cavity, as well as between the spiral air duct shell 4415 itself. See also Figure 14 As indicated by the arrow, the airflow entering from the exhaust inlet 421 flows in a rotating manner within the rotating duct 442, enters the innermost cavity of the spiral duct shell 4415 through the spiral duct inlet 4416, and then flows out from the rotating duct outlet 431. The use of the spiral duct shell 4415 to form a multi-circulation rotating duct greatly increases the length of the exhaust duct located at the rear end of the fan 37, reduces the exhaust air velocity, and decreases exhaust noise.

[0086] In some embodiments, the third filter element 45 includes a bottom frame 451, a top cover 452, and a filter element 453 located between the bottom frame 451 and the top cover 452. The bottom frame 451 is fitted to the upper surface of the exhaust partition plate 43, and the top cover 452 is fitted to the exhaust top cover 47. The filter element 453 has an annular structure, and correspondingly, the bottom frame 451 has an annular structure, and the top cover 452 has a disc-shaped structure. By configuring the third filter element 45 with a structure having a bottom frame 451 and a top cover 452, it is convenient to seal the third filter element 45 with other structural components.

[0087] In some embodiments, the filter element 453 uses a HEPA filter. In some embodiments, the bottom frame 451 is made of a soft rubber material to facilitate sealing between the bottom frame 451 and the exhaust partition plate 43. The top cover 452 is made of a rigid composite material to facilitate its assembly with the exhaust top cover 47 and / or the exhaust housing 41 and / or the exhaust inner housing.

[0088] See also Figures 1 to 5 , Figure 11 As shown, the exhaust cover 47 includes a cover flange 471, a cover plate 472, and a cover exhaust port 473. The cover flange 471 is folded downwards, and several slots 4711 are provided on the outer wall of the cover flange 471. The exhaust housing 41 has locking protrusions that engage with the slots 4711 to achieve a snap-fit ​​installation. The exhaust cover 47 is detachably assembled with the exhaust housing 41 via the slots 4711. The cover plate 472 is located in the middle of the exhaust cover 47, and the cover exhaust port 473 surrounds the outer periphery of the cover plate 472 and communicates with the exhaust duct 46. An operating part 4721 is provided on the cover plate 472. Using the operating part 4721, the exhaust cover 47 can be rotated to install the exhaust cover 47 onto the exhaust housing 41, or to remove the exhaust cover 47 from the exhaust housing 41.

[0089] In some embodiments, the exhaust top cover 47 is not connected to the third filter element 45. After the exhaust top cover 47 is removed from the exhaust housing 41 using the operating part 4721, the third filter element 45 is removed from the exhaust inner housing 42 and taken out to clean dust and other impurities on the third filter element 45, and to clean or replace the third filter element 45.

[0090] In some embodiments, the exhaust top cover 47 is connected to the third filter element 45. When the exhaust top cover 47 is removed from the exhaust housing 41 using the operating part 4721, the exhaust top cover 47 and the third filter element 45 are removed together, so that dust and other impurities on the third filter element 45 can be cleaned, and the third filter element 45 can be cleaned or replaced.

[0091] In some embodiments, such as Figure 11 As shown, the operating part 4721 is at least two grooves or handles formed on the top cover plate 472 to facilitate rotation of the exhaust top cover 47.

[0092] See also Figures 1 to 3 , Figure 5 as well as Figure 8As shown, the handle assembly 5 includes a handle housing, which includes a grip portion 51 and a connecting portion 52, forming a gripping space 53 between the grip portion 51 and the connecting portion 52. The gripping space 53 can accommodate the hand and provides space for flexible hand movement, facilitating a firm grip on the grip portion 51 with the entire hand. The connecting portion 52 includes a horizontally arranged horizontal connecting portion 521 and a vertically arranged vertical connecting portion 522. The bottom end of the vertical connecting portion 522 is connected to the end of the horizontal connecting portion 521 near the dust cup assembly 2, forming an L-shaped structure with the horizontal connecting portion 521. The top end of the vertical connecting portion 522 is connected to the end of the fan housing 31 of the airflow generating assembly 3 near the exhaust assembly 4, and the entire vertical connecting portion 522 is also connected to the dust cup shell 20 of the dust cup assembly 2. The bottom end of the grip 51 is connected to the horizontal connecting part 521 at a position away from the vertical connecting part 522, and the top end of the grip 51 is connected to the end of the fan housing 31 away from the exhaust assembly 4. As a result, the weight of the fan 37, which is horizontally arranged inside the airflow generating assembly 3, is distributed and supported by the grip 51 and the connecting part 52, making it easier and less strenuous to lift the cleaning equipment via the handle assembly 5.

[0093] In some embodiments, the grip 51 is tilted and its bottom end moves away from the dust cup assembly 2, so that the bottom end of the grip 51 is further away from the center of gravity of the cleaning device in the horizontal direction, making it easier and more stable to lift the cleaning device for cleaning operations.

[0094] See also Figures 1 to 3 and Figure 5 As shown, the power supply unit 6, which supplies power to the cleaning equipment, is located at the lower part of the handle assembly 5. By placing the power supply unit 6 below the handle assembly 5, the weight can be balanced with the airflow generating assembly 3 located above the handle assembly 5. This allows the cleaning equipment to be easily and effortlessly lifted via the handle assembly 5 when in use, and to be placed stably when not in use.

[0095] In some embodiments, the power supply assembly 6 includes a power housing 61 and a power supply 62 located inside the power housing 61. The power housing 61 is detachably assembled with the handle assembly 5. By adopting a detachable assembly structure between the power supply assembly 6 and the handle assembly 5, it is easy to disassemble the power supply assembly 6 to facilitate the handling of the power supply 62 in the power supply assembly 6.

[0096] In some other embodiments, the cleaning device may also exclude the power supply component 6 and utilize an external power source to power the cleaning device.

[0097] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present invention.
