A handle is provided on the top of the operating body. The user supports and pushes and pulls the operating body through the handle to drive the suction head to move. A dust box is usually provided on the operating body. The dust box is correspondingly provided with a dust and gas separation structure. The dust box and the dust and gas separation structure are integrated and arranged on the top of the operating body.

[0004] However, in the current structure of vacuum cleaners, the dust box and the dust and gas separation structure are assembled at the gripping position on the top of the product, which is large in size and weight.

[0008] The dust collection component provided by this application inserts the air inlet pipe into the dust collection housing, and uses the inner wall of the dust collection housing to form a dust collection cavity outside the air inlet pipe, making full use of the space inside the dust collection housing. And the flow guiding component is arranged at the cyclone outlet at the top of the air inlet pipe, so that when the air flow flows out from the cyclone outlet, it can separate dust and sundries by using rotational and centrifugal movements.

[0018] With such a setting, the airflow passing through the cyclone outlet can form a cyclone under the guidance of the first flow guiding member, thereby achieving dust-gas separation by using centrifugal force.

[0019] As an alternative embodiment, the first flow guiding member may include a plurality of flow guiding vanes, and the plurality of flow guiding vanes are arranged at intervals around the central axis of the air inlet pipe.

[0022] With such a setting, the airflow flowing out from the cyclone outlet can be guided to accelerate and rotate and diffuse towards the inner walls around the dust collecting housing, improving the dust-gas separation efficiency.

[0023] As an alternative embodiment, the flow guiding ball is coaxially arranged with the air inlet pipe.

[0024] With such a setting, the smoothness of the airflow flowing out from the cyclone outlet can be ensured, and the generation of turbulent flow at the cyclone outlet can be avoided.

Therefore, it should not be construed as a limitation to the present application.

[0060] The terms "first", "second", "third" (if any) in the description, claims and drawings of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

For example, a process, method, system, product or maintenance tool that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or maintenance tools.

[0062] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0063] A vacuum cleaner generally includes a suction head and an operation main body connected to the suction head. The suction head can be dragged on the ground. A handle is provided at the top of the operation main body. The user holds and pushes and pulls the operation main body through the handle, thereby driving the suction head to move. A dust collection box is usually provided on the operation main body. A dust-gas separation structure is correspondingly provided for the dust collection box. The dust collection box and the dust-gas separation structure are integrally provided at the top of the operation main body.

[0064] However, in the current structure of the vacuum cleaner, the dust collection box and the dust-air separation structure are assembled at the holding position on the top of the product, which are relatively large in volume and weight. When using the vacuum cleaner, a relatively large force is required to lift it, and users are prone to fatigue during use.

[0065] To solve the above technical problems, the embodiments of the present application provide a dust collection assembly and a cleaning device. The inner wall of the dust collection housing forms a dust collection chamber outside the air inlet pipe, making full use of the space inside the dust collection housing. And the flow guiding assembly is arranged at the cyclone outlet at the top of the air inlet pipe, so that when the air flow flows out from the cyclone outlet, it can separate dust and sundries by using rotational and centrifugal motions. While having a good dust-air separation effect, the volume of the entire dust collection assembly is reduced to form a long cylindrical structure. Therefore, when applied to a cleaning device, it can reduce the overall weight of the cleaning device, lower the overall center of gravity, avoid the weight concentrating on the holding end of the cleaning device, and improve the user experience.

[0066] For ease of understanding, first, the application scenarios of the dust collection assembly and the cleaning device provided by the embodiments of the present application will be described.

[0067] The dust collection assembly provided by the embodiments of the present application can be applied to a cleaning device. The cleaning device has a dust suction function, including but not limited to vacuum cleaners, floor washing machines, suction and mopping integrated machines, etc. The cleaning device can be used for household cleaning or for floor cleaning in other indoor or outdoor scenarios. The embodiments of the present application do not limit the specific product types to which the dust suction device is applied and the specific application scenarios of the cleaning device.

[0068] Figure 1 is a schematic structural diagram of the dust collection assembly provided by the embodiments of the present application; Figure 2 is an exploded view of the dust collection assembly provided by the embodiments of the present application; Figure 3 is a cross-sectional view of the air inlet pipe in the dust collection assembly provided by the embodiments of the present application.

[0069] See Figures 1 to 3 As shown, the present application provides a dust collection assembly 100. The dust collection assembly 100 can be applied to a cleaning device. The cleaning device has a dust suction function. The inhaled dust-laden air enters the dust collection assembly 100 for dust-air separation, and the dust and sundries can be separated and collected in the dust collection assembly 100.

[0070] In some embodiments, the dust collection assembly 100 includes a dust collection housing 112, an air inlet pipe 113, and a flow guiding assembly 114. The air inlet pipe 113 is connected to the dust collection housing 112, and at least part of the structure of the air inlet pipe 113 is inserted into the dust collection housing 112. The outer wall of the air inlet pipe 113 and the inner wall of the dust collection housing 112 enclose to form a dust collection chamber 111. The dust collection chamber 111 is used to store the separated dust and sundries.

[0071] Among them, the air inlet pipe 113 is provided with an air inlet 1131 and a cyclone outlet 1132. The air inlet 1131 faces the outside of the dust collection housing 112, and the cyclone outlet 1132 faces the inside of the dust collection housing 112. The diversion assembly 114 is arranged inside the dust collection housing 112. The dust collection housing 112 is provided with an air outlet 1122 on the side of the diversion assembly 114 facing away from the air inlet pipe 113. The diversion assembly 114 is opposite to the cyclone outlet 1132 and at least part of its structure is located inside the air inlet pipe 113, so as to form a swirling flow channel between the diversion assembly 114 and the inner wall of the air inlet pipe 113.

[0072] It can be understood that the external dust-laden air can enter the air inlet pipe 113 from the air inlet 1131. When flowing out from the cyclone outlet 1132, a cyclone will be formed through the cyclone channel between the diversion assembly 114 and the air inlet pipe 113. The diversion assembly 114 can guide the flow of the dust-laden air, so that dust and sundries can be separated by using rotational and centrifugal motions.

[0073] It should be noted that in the dust collection assembly 100 provided by the embodiment of the present application, the inner wall of the dust collection housing 112 forms a dust collection chamber 111 outside the air inlet pipe 113, making full use of the space inside the dust collection housing 112. And the diversion assembly 114 is arranged at the cyclone outlet 1132 at the top of the air inlet pipe 113 to separate the dust-laden air at the end of the air inlet pipe 113. While having a good dust-laden air separation effect, the volume of the entire dust collection assembly 100 is reduced to form a long cylindrical structure. Therefore, when applied to a cleaning device, the overall weight of the cleaning device can be reduced, the overall center of gravity can be lowered, and the weight concentration at the holding end of the cleaning device can be avoided, improving the user experience.

[0074] In some embodiments, the air inlet pipe 113 and the dust collection housing 112 are coaxially arranged, and the dust collection chamber 111 surrounds the circumferential outside of the air inlet pipe 113. An annular dust collection space is formed outside the circumference of the air inlet pipe 113. The dust collection chamber 111 can utilize the space on the circumferential side of the air inlet pipe 113, making the weight distribution of the dust collection assembly 100 along the axial direction more uniform and avoiding local overweight caused by weight concentration.

[0075] It can be understood that the height of the area where the dust collection chamber 111 can accommodate dust and sundries can be approximately the same as the height of the air inlet pipe 113. Since the air inlet pipe 113 is coaxially inserted into the dust collection housing 112, the dust collection chamber 111 makes full use of the internal space of the dust collection housing 112. The air inlet pipe 113 at the center of gravity position of the dust collection chamber 111 is used to introduce the dust-laden air, while the circumferential space is used to store the dust and sundries after the dust-laden air is separated.

[0076] In some embodiments, the first end of the air inlet pipe 113 is connected to the first end of the dust collection housing 112, and the air inlet 1131 is provided at the first end of the air inlet pipe 113. The second end of the air inlet pipe 113 is inserted into the interior of the dust collection housing 112 and extends toward the second end of the dust collection housing 112. The cyclone outlet 1132 is provided at the second end of the air inlet pipe 113, and the air outlet 1122 is located at the second end of the dust collection housing 112. The air inlet pipe 113 has a sufficient length, which correspondingly enables the dust collection chamber 111 to have a relatively large storage space, preventing dust from overflowing into the air inlet pipe 113.

[0077] It can be understood that the air inlet pipe 113 and the dust collection housing 112 can form a structure of being sleeved inside and outside. When forming the dust collection chamber 111, the space in the length direction of the air inlet pipe 113 inside the dust collection housing 112 can be fully utilized, improving the space utilization rate and increasing the volume of the dust collection chamber 111.

[0078] In some embodiments, the air inlet pipe 113 may include a pipe body 1133 and a connection portion 1134. The connection portion 1134 is hermetically connected to the first end of the dust collection housing 112, and the pipe body 1133 is connected to the connection portion 1134. The air inlet 1131 and the cyclone outlet 1132 are respectively located at the axial two ends of the pipe body 1133, thereby ensuring the connection reliability between the air inlet pipe 113 and the dust collection housing 112. The airflow entering the air inlet pipe 113 flows along its axis, improving the smoothness of the airflow. The connection portion 1134 is hermetically sealed with the dust collection housing 112 at the bottom, ensuring the tightness of the dust collection chamber 111 and preventing dust from leaking out from the connection position between the bottom of the air inlet pipe 113 and the dust collection housing 112.

[0079] Exemplarily, a first threaded portion 1121 may be provided on the inner wall of the first end of the dust collection housing 112, and a second threaded portion 1135 may be provided on the outer wall of the connection portion 1134. The first threaded portion 1121 is screwed with the second threaded portion 1135 to achieve threaded sealing. The connection portion 1134 is provided with a stepped portion below the second threaded portion 1135, and the stepped portion abuts against the end face of the first end of the dust collection housing 112. The stepped portion can limit the screwing depth of the connection portion 1134 and the dust collection housing 112, improving the sealing performance of the connection position between the dust collection housing 112 and the air inlet pipe 113.

[0080] It should be noted that the air inlet pipe 113 and the dust collection housing 112 can also be connected by ultrasonic welding, induction welding, glue bonding, etc. The embodiments of the present application do not make specific limitations on this.

[0081] In some embodiments, the flow guiding assembly 114 may include a first flow guiding member 1141, and the first flow guiding member 1141 is disposed at one end of the air inlet pipe 113 close to the cyclone outlet 1132. The first flow guiding member 1141 is connected to the inner wall of the air inlet pipe 113, and the first flow guiding member 1141 spirally extends along the axis of the air inlet pipe 113.

[0082] It is understandable that the airflow passing through the cyclone outlet 1132 can form a cyclone under the guidance of the first deflector 1141, thereby realizing the separation of dust and gas by using centrifugal force.

[0083] Figure 4 Structure one of the air inlet pipe in the dust collection assembly provided by the embodiment of the present application; Figure 5 Structure two of the air inlet pipe in the dust collection assembly provided by the embodiment of the present application; Figure 6 Structure three of the air inlet pipe in the dust collection assembly provided by the embodiment of the present application.

[0084] Please refer to Figures 4 to 6 and in combination with Figures 1 to 3 Exemplarily, the first deflector 1141 may include a plurality of deflector vanes 1141a. The plurality of deflector vanes 1141a are arranged at intervals around the central axis of the air inlet pipe 113. The plurality of deflector vanes 1141a can form a plurality of flow channels, improving the efficiency and flow rate of the airflow flowing out of the air inlet pipe 113 to form a cyclone, and further increasing the centrifugal force for throwing out dust and sundries during dust-gas separation, having a better dust-gas separation effect and efficiency.

[0085] Exemplarily, the number of the deflector vanes 1141a may be two, three, four or more. The embodiment of the present application does not make specific limitations on this.

[0086] Please continue to refer to Figures 1 to 3 In some embodiments, the deflector assembly 114 may include a second deflector 1142. The second deflector 1142 is located between the cyclone outlet 1132 and the air outlet 1122. The second deflector 1142 may include a deflector bracket 1143 and a deflector ball 1144. The deflector bracket 1143 is connected to the inner wall of the dust collection housing 112, and the deflector ball 1144 is connected to the deflector bracket 1143. At least part of the structure of the deflector ball 1144 is inserted into the cyclone outlet 1132. The airflow flowing out of the cyclone outlet 1132 can be guided to accelerate and rotate and diffuse towards the inner walls around the dust collection housing 112, improving the dust-gas separation efficiency.

[0087] It is understandable that on the one hand, the deflector bracket 1143 serves to fix the deflector ball 1144. On the other hand, when the dust and gas at the cyclone outlet 1132 are discharged, under the guidance of the deflector ball 1144, the airflow will continue to flow upward and diffuse around. The deflector bracket 1143 can block the airflow and cause the dust and sundries separated under the action of centrifugal force to settle downward.

[0088] Exemplarily, the deflector ball 1144 is coaxially arranged with the air inlet pipe 113, so as to ensure the smoothness of the airflow flowing out of the cyclone outlet 1132 and avoid the generation of turbulence at the cyclone outlet 1132.

[0089] In some embodiments, the inner wall of the cyclone outlet 1132 encloses an air outlet area, and the diameter of the radial cross-section of the air outlet area gradually increases in the direction towards the outside of the cyclone outlet 1132. The end of the diversion ball 1144 is inserted into the air outlet area.

[0090] It can be understood that the cyclone outlet 1132 can form a trumpet-shaped structure, which is used to increase the flow cross-sectional area of the cyclone outlet 1132, facilitating the outward diffusion of the air flow from the cyclone outlet 1132, thereby more efficiently separating dust from gas. Since the diversion ball 1144 is inserted into the air outlet area, the diversion ball 1144 will compress the ventilation area of the cyclone outlet 1132, enabling the air flow to increase its velocity while diffusing in all directions, and thus increasing the centrifugal force of dust and debris during the dust-gas separation in the cyclone.

[0091] Exemplarily, the cross-sectional dimension of the diversion ball 1144 along the radial direction of the dust collection housing 112 first increases and then decreases from the diversion bracket 1143 towards the inside of the cyclone outlet 1132. Among them, the cross-sectional dimension of the part of the diversion ball 1144 inserted into the cyclone outlet 1132 gradually decreases. The air outlet area of the cyclone outlet 1132 can be controlled by the diversion ball 1144, and thus the wind speed and wind pressure of the air flow can be controlled, enabling the air flow to continue to rotate after being discharged from the cyclone outlet 1132 and maintaining the effect of dust-gas separation.

[0092] In some embodiments, ventilation holes 1143a are provided on the diversion bracket 1143. The ventilation holes 1143a communicate the dust collection chamber 111 and the air outlet 1122. The ventilation holes 1143a are arranged near the connection position of the diversion ball 1144 and the diversion bracket 1143. The ventilation holes 1143a are used for the air flow after dust-gas separation to flow out. Since the ventilation holes 1143a are arranged near the root of the diversion ball 1144, the ventilation holes 1143a are as close as possible to the central position of the diversion bracket 1143, which can prevent the air flow with dust from directly entering the through holes when being discharged from the cyclone outlet 1132.

[0093] It should be noted that the diversion bracket 1143 can be connected to the inner wall of the dust collection housing 112 by welding, or the diversion bracket 1143 can be relatively fixed to the inner wall of the dust collection housing 112 by clamping and limiting.

[0094] In the embodiments of the present application, the dust collection assembly 100 may further include a filter 1145, and the filter 1145 is arranged between the diversion assembly 114 and the air outlet 1122. The air inlet pipe 113, the diversion assembly 114, and the filter 1145 are arranged in sequence along the axial direction of the dust collection housing 112. In this way, the overall volume of the dust collection assembly 100 is reduced, and the weight distribution of the dust collection assembly 100 along the axial direction is more uniform.

[0095] Exemplarily, the filter 1145 may include a High Efficiency Particulate Air Filter (HEPA Filter), and the filter 1145 may filter micron-sized dust impurities, thereby ensuring the cleanliness of the air flowing out of the dust collection assembly 100.

[0096] It should be noted that the air inlet pipe 113 and the filter 1145 can be connected to the dust collecting shell 112 in a detachable manner, including but not limited to threaded connection, snap connection, elastic interference fit, etc., and the embodiments of the present application do not specifically limit this.

[0097] In some embodiments, a spoiler 1136 is disposed on the outer wall of the air inlet pipe 113 . The spoiler 1136 protrudes from the outer surface of the air inlet pipe 113 and abuts against the inner wall of the dust collecting housing 112 .

[0098] It is understandable that when the airflow enters the dust collecting chamber 111 and rotates to throw out dust and debris, the spoiler 1136 can block the airflow and dust and debris as the airflow rebounds and sinks, thereby accelerating the falling of dust and debris. In addition, since the airflow blocked by the guide bracket 1143 will rebound downward, the spoiler 1136 can prevent the rebounding airflow from bringing up the settled dust.

[0099] Exemplarily, the spoiler 1136 may be disposed at the top or the middle of the air inlet pipe 113. The spoiler 1136 may be welded to the outer wall of the air inlet pipe 113.

[0100] In some embodiments, there may be a plurality of spoilers 1136, and the plurality of spoilers 1136 are spaced apart around the circumference of the air inlet pipe 113. The end of the spoiler 1136 away from the air inlet pipe 113 abuts against the inner wall of the dust collecting housing 112, thereby having a better spoiler effect and further accelerating the falling of dust and debris into the dust collecting chamber 111.

[0101] It should be noted that when the air inlet pipe 113 is assembled with the dust collecting shell 112, the air inlet pipe 113 is inserted into the dust collecting shell 112, the connecting portion 1134 at the lower end is threadedly connected to the dust collecting shell 112, and the spoiler portion 1136 at the upper end abuts against the inner wall of the dust collecting shell 112, thereby maintaining the stability of the air inlet pipe 113 in the dust collecting shell 112 and avoiding radial displacement or shaking of the air inlet pipe 113.

[0102] In some embodiments, the diameter of the radial cross-section of the dust collecting component 100 is 35 mm-50 mm, which can ensure that the dust collecting chamber 111 has a sufficiently large dust collecting space while controlling the overall radial size of the dust collecting component 100 within a reasonable range, so that the dust collecting component 100 forms a slender rod-like structure as part of the main structure of the cleaning equipment, thereby realizing a lightweight design of the product.

[0103] It can be understood that the diameter dimension of the radial cross-section of the dust collection assembly 100 can be approximately the same as the radial cross-section dimension of the outer contour of the dust collection housing 112. Exemplarily, the cross-sectional shape of the dust collection housing 112 can be circular, or the cross-sectional shape of the dust collection housing 112 can also be elliptical or other regular polygons, and the embodiments of the present application do not make specific limitations thereto.

[0104] Exemplarily, the specific numerical values of the diameter dimension of the radial cross-section of the dust collection assembly 100 can include but are not limited to 35 mm, 36 mm, 40 mm, 45 mm, 49 mm, 50 mm, and the embodiments of the present application do not make specific limitations thereto.

[0105] In a possible implementation manner, the dust collection assembly 100 may further include a dust collection chamber cover 115. A dust discharge port communicating with the dust collection chamber 111 is provided on the side wall of the dust collection housing 112. The dust collection chamber cover 115 is connected to the outer wall of the dust collection housing 112 and blocks the dust discharge port, so that the dust and objects in the dust collection chamber 111 can be cleaned without disassembling the dust collection assembly 100.

[0106] Wherein, the dust collection chamber cover 115 is movably arranged relative to the dust discharge port to open or close the dust discharge port.

[0107] It can be understood that when the cleaning device is in normal use, the dust collection chamber cover 115 closes the dust discharge port to prevent dust from leaking out. When it is necessary to clean the dust collection chamber 111, the dust collection chamber cover 115 can be opened, and the dust and sundries in the dust collection chamber 111 can be poured out from the dust discharge port.

[0108] It should be noted that in the dust collection assembly 100 provided by the embodiments of the present application, the dust collection chamber 111 is formed by using the space between the inside of the dust collection housing 112 and the air inlet pipe 113. Therefore, when it is necessary to clean the dust and sundries in the dust collection chamber 111, only the dust discharge port on the outer wall of the housing needs to be opened, and there is no need to remove the dust collection assembly 100 from the cleaning device, which improves the convenience of cleaning the dust collection chamber 111.

[0109] Figure 7 is a schematic structural diagram of the cleaning device provided by the embodiments of the present application; Figure 8 is an exploded view of the cleaning device provided by the embodiments of the present application; Figure 9 is a schematic structural diagram of the collection box in the cleaning device provided by the embodiments of the present application; Figure 10 is a cross-sectional view of the collection box in the cleaning device provided by the embodiments of the present application; Figure 11 is an exploded view of the collection box in the cleaning device provided by the embodiments of the present application; Figure 12 is an internal view of the collection box in the cleaning device provided by the embodiments of the present application; Figure 13 is a schematic structural diagram of the fan assembly in the cleaning device provided by the embodiments of the present application.

[0110] Please refer to Figures 7 to 13 , and in combination with Figures 1 to 3 , an embodiment of the present application provides a cleaning device, which includes the dust collection component 100, the fan component 120, and the suction cup 200 in the above technical solution. The suction cup 200 is movably connected to the dust collection component 100. The suction cup 200 is provided with a suction port 201 and a collection chamber 202. The suction port 201 is communicated with the collection chamber 202, and a filter element 210 is provided in the collection chamber 202. The dust-laden air inhaled from the suction port 201 can enter the collection chamber 202, flow out after being filtered by the filter element 210, and the collection chamber 202 can store the filtered dust and debris.

[0111] Among them, the air inlet side of the fan component 120 is communicated with the dust collection chamber 111, the dust collection chamber 111 is communicated with the collection chamber 202, and a dust-gas separation structure is provided in the dust collection chamber 111. The dust-laden air flowing out from the collection chamber 202 can enter the dust collection chamber 111 for dust-gas separation. The separated dust and debris settle and are collected in the dust collection chamber 111, while the separated air is discharged from the dust suction device.

[0112] It can be understood that spaces for filtering, separating, and collecting dust and debris are respectively provided on the suction cup 200 and the dust suction device, forming a two-stage filtering structure. The two-stage filtering can distinguish dust and debris of different volumes and store them in different spaces respectively.

[0113] It should be noted that in the cleaning device provided in the present application, the dust and debris inhaled from the suction port 201 can first be filtered by the collection chamber 202, and part of the large-volume debris is left in the collection chamber 202. Then, the dust-gas separation can be carried out through the dust collection chamber 111, and the remaining dust and debris are collected and stored. In this way, the filtering efficiency of the cleaning device for dust and debris is improved, secondary pollution is avoided, and the dust and debris can be stored in two independent spaces, having a larger space for storing dust and debris, avoiding frequent cleaning by users, preventing fine dust from being inhaled into the human body, and improving the user experience.

[0114] In a possible implementation manner, the collection chamber 202 has a suction inlet 2021 and a discharge outlet 2022. The suction inlet 2021 and the discharge outlet 2022 are respectively located on opposite sides of the collection chamber 202. The suction inlet 2021 is communicated with the suction port 201, and the discharge outlet 2022 is communicated with the dust collection chamber 111. The dust-laden air inhaled from the suction port 201 can enter the collection chamber 202 from the suction inlet 2021, then flow out of the collection chamber 202 from the discharge outlet 2022, and flow to the dust collection chamber 111.

[0115] It can be understood that a channel for dust and sundries to settle can be formed between the suction port 2021 and the discharge port 2022. When the airflow inhaled from the suction port 2021 enters the collection chamber 202, some sundries and particles can be retained in the collection chamber 202, improving the collection efficiency.

[0116] In some embodiments, the filter element 210 can divide the collection chamber 202 into a first chamber 202a and a second chamber 202b. The suction port 2021 is communicated with the first chamber 202a, and the discharge port 2022 is communicated with the second chamber 202b. The volume of the first chamber 202a is larger than that of the second chamber 202b. When the airflow flows from the suction port 2021 to the discharge port 2022, the filter element 210 can be used for filtering, so as to collect large-volume sundries and particles in the collection chamber 202.

[0117] It can be understood that the airflow with dust and sundries first passes through the first chamber 202a, and the large-volume sundries filtered by the filter element 210 will be collected and retained in the first chamber 202a. The function of the second chamber 202b is to provide a space and a channel for the dust-laden gas to converge towards the discharge port 2022.

[0118] Exemplarily, the filter element 210 can be in a plate-like structure. The filter element 210 can be vertically arranged in the collection chamber 202. The edge of the filter element 210 can be welded to the inner wall of the collection chamber 202, or slidably inserted through a chute structure, or fixedly connected by a buckle. The embodiments of the present application do not make specific limitations on this.

[0119] In some embodiments, the filter element 210 is provided with a plurality of mesh holes 211, and the plurality of mesh holes 211 are arranged in an array on the filter element 210. The aperture of the mesh holes 211 is 0.2 mm - 1 mm. Dust and small-volume sundries with a diameter smaller than the mesh holes 211 can enter the dust collection chamber 111 along with the airflow through the filter element 210, while sundries with a size larger than the mesh holes 211 will be collected and retained in the collection chamber 202.

[0120] It can be understood that the filter element 210 can classify the dust and sundries that need to be collected and stored. On the one hand, it prevents large-volume sundries from entering the dust collection chamber 111, and on the other hand, it prevents the collection chamber 202 from being filled with too much dust and sundries and overflowing too quickly.

[0121] Exemplarily, the specific sizes of the aperture that the mesh holes 211 can adopt can include but are not limited to 0.2 mm, 0.3 mm, 0.5 mm, 0.9 mm, 1 mm, etc. The embodiments of the present application do not make specific limitations on this.

[0122] In some embodiments, the suction inlet 2021 may be provided with a flexible baffle 220. The flexible baffle 220 is arranged on the side of the suction inlet 2021 facing the inside of the collection chamber 202, so as to ensure the unidirectional flow of air through the suction inlet 2021 and prevent dust and debris in the collection chamber 202 from leaking out through the suction inlet 2021.

[0123] It can be understood that when the dust-laden air at the suction opening 201 is sucked into the collection chamber 202 under the action of negative pressure, the flexible baffle 220 undergoes elastic deformation under the pressure difference between the inside and outside of the collection chamber 202 and opens the suction inlet 2021, allowing the dust-laden air to enter the collection chamber 202. When the device is not started, the flexible baffle 220 returns to its initial state and blocks the suction inlet 2021.

[0124] Exemplarily, the material of the flexible baffle 220 can be an elastic material such as rubber or silica gel, and the embodiments of the present application do not make specific limitations thereto.

[0125] In some embodiments, the suction cup 200 may include a base 230 and a collection box 240. The collection box 240 is detachably connected to the base 230. The suction opening 201 is provided at the bottom of the base 230. The collection box 240 is configured to form a collection chamber 202 to facilitate the cleaning of dust and debris in the collection chamber 202.

[0126] It can be understood that the collection box 240 can be installed above the base 230. The collection box 240 can be connected to the base 230 in a snap-fit structure form. The base 230 is provided with limiting ribs or limiting grooves to ensure the accuracy of the installation position of the collection box 240, thereby avoiding misalignment when the suction inlet 2021 and the discharge outlet 2022 are structurally docked on the base 230.

[0127] Exemplarily, the front end of the collection box 240 along the cleaning direction of the suction cup 200 is communicated with the suction opening 201, and the rear end of the collection box 240 along the cleaning direction of the suction cup 200 is communicated with the dust collection chamber 111, so as to reduce the turning of the air flow during the dust suction process, improve the smoothness of the air flow, and thus improve the dust suction efficiency.

[0128] Exemplarily, the collection box 240 includes a box body 241 and a box cover 242. The box body 241 and the box cover 242 are rotatably opened and closed and can be fixed by snaps. A sealing ring 243 is arranged between the box body 241 and the box cover 242. The box cover 242 is provided with a blocking rib. When the box cover 242 is closed relative to the box body 241, the top end of the filter element 210 abuts against or is adjacent and staggered with the blocking rib, so as to separate the collection chamber 202.

[0129] The structure of the fan assembly 120 will be described in detail below.

[0130] In a possible implementation, the fan assembly 120 may include a fan housing 121, a fan unit 122, a first buffer member 123, and a second buffer member 124. The fan housing 121 is connected to the air outlet 1122. The fan unit 122 is disposed within the fan housing 121. The first buffer member 123 and the second buffer member 124 are respectively disposed at two axial ends of the fan unit 122, and both the first buffer member 123 and the second buffer member 124 are abutted between the fan unit 122 and the inner wall of the fan housing 121.

[0131] It can be understood that the first buffer member 123 and the second buffer member 124 can play a good role in shock absorption and buffering for the fan unit 122. When the fan unit 122 is operating, it can prevent the vibration of the fan unit 122 from being transmitted to the fan housing 121, and reduce the noise during the operation of the fan assembly 120.

[0132] Exemplarily, both the first buffer member 123 and the second buffer member 124 can be elastic members made of materials such as rubber or silica gel. Both the first buffer member 123 and the second buffer member 124 can be in the structure of an annular washer. The present application embodiment does not limit the specific materials and shapes of the first buffer member 123 and the second buffer member 124.

[0133] Exemplarily, the cross-sectional shape of the fan housing 121 can be circular, or the cross-sectional shape of the dust collection housing 112 can also be elliptical or other regular polygons. The present application embodiment does not make specific limitations thereto.

[0134] Exemplarily, the diameter dimension of the radial cross-section of the fan housing 121 is 35 mm - 50 mm. The specific numerical values of the diameter dimension of the radial cross-section of the fan housing 121 may include but are not limited to 35 mm, 36 mm, 40 mm, 45 mm, 49 mm, 50 mm. The present application embodiment does not make specific limitations thereto. In this way, the radial dimension of the fan housing 121 is controlled within a reasonable range, so that the fan assembly 120 forms an elongated rod-shaped structure as a part of the dust suction device, realizing the lightweight design of the product.

[0135] In a possible implementation, the cleaning device further includes a battery assembly 130. The dust collection assembly 100, the fan assembly 120, and the battery assembly 130 are coaxially arranged. In this way, along the axial direction of the dust suction device, the dust collection assembly 100, the fan assembly 120, and the battery assembly 130 can be arranged in sequence, respectively constituting a part of the structure, so that the overall dust suction device forms an elongated rod-shaped structure.

[0136] It is understandable that the dust collecting assembly 100 provides a channel for dust and gas circulation while using its own structure to form a separation and storage space for dust and debris. The fan assembly 120 is located in the middle of the dust collecting device. Compared with the prior art in which the fan is set at the top, the weight of the end of the dust collecting device in the embodiment of the present application is smaller. The top of the dust collecting device is formed into a rod-shaped structure by the battery assembly 130, which is convenient for the user to hold when using it, and the operation is more labor-saving.

[0137] It should be noted that the dust collecting device provided by the present application can be used in cleaning equipment to play the role of the operating body, and the coaxially assembled dust collecting component 100, fan component 120, and battery component 130 form a rod-shaped structure for the user to hold when using. Since the three components are arranged in sequence, the axial weight distribution of the overall structure of the dust collecting device is more uniform, and the structure is more compact and small, achieving the lightweight effect of the dust collecting device, reducing the weight of the hand holding position during use, and improving the user experience.

[0138] In some embodiments, the battery assembly 130 may include a battery rod body, a battery cell and an electronic control board. The battery rod body is connected to the fan assembly 120. The battery rod body has an electronic control cavity and a battery cavity distributed along the axial direction of the device. The battery cavity is located on the side of the electronic control cavity away from the fan assembly 120. The battery cell is arranged in the battery cavity, and the electronic control board is arranged in the electronic control cavity.

[0139] It is understandable that the battery rod body as a supporting structure can separate the installation space of the battery unit and the electric control board in the axial direction to avoid the weight concentration of the battery assembly 130 causing the weight and size of the end of the dust collection device to be too large. The battery unit is used to power the electric control board and the fan assembly 120 and other electrical devices, and the electric control board can control the operation of the fan assembly 120.

[0140] In some embodiments, there may be multiple battery cells, and the multiple battery cells are arranged in sequence along the axial direction of the battery rod body in the battery cavity, which can ensure that the weight of the battery cells is evenly distributed.

[0141] For example, a plurality of battery cells may be arranged in series in sequence. A user may replace a battery cell by opening the battery cavity.

[0142] In some embodiments, a wiring cavity is provided in the battery cavity along the radial side of the battery rod body, a switch unit is provided at one end of the battery rod body away from the fan assembly 120, a signal line is provided in the wiring cavity, and the signal line is configured to electrically connect the switch unit to the control board. The operation of the fan assembly 120 can be controlled by the switch unit, and the user only needs to press or touch the switch unit at the end of the battery rod body, thereby improving the convenience of operating the switch unit for users.

[0143] Exemplarily, the switch unit may be a push switch, a toggle switch, or a touch switch, which is not specifically limited in the embodiments of the present application.

[0144] In some embodiments, the diameter of the radial cross section of the battery rod can be 30 mm to 40 mm. In this way, the diameter of the battery rod can be controlled within a reasonable range to ensure that the user has a good operating feel when holding the battery rod, and it is easier and more labor-saving to drag or push the cleaning device by holding the battery rod.

[0145] For example, the specific value of the diameter size of the radial cross section of the battery rod body may include but is not limited to 30 mm, 31 mm, 35 mm, 39 mm, and 40 mm, and the embodiments of the present application do not make specific limitations on this.

[0146] In a possible implementation, the cleaning device may further include a flexible connecting tube 300, the two ends of which are respectively connected to the dust collecting assembly 100 and the suction cup 200, and the flexible connecting tube 300 is configured to form a dust collecting air duct connecting the collection chamber 202 and the dust collecting chamber 111. In this way, while ensuring the flexibility of the suction cup 200, the smoothness of the airflow from the suction cup 200 into the dust collecting device is improved.

[0147] The present application provides a dust collection assembly and a cleaning device, which includes a dust collecting shell, an air inlet duct and a guide assembly, the air inlet duct being connected to the dust collecting shell, and at least a portion of the structure of the air inlet duct being inserted into the dust collecting shell, the outer wall of the air inlet duct and the inner wall of the dust collecting shell forming a dust collecting chamber, the air inlet duct being provided with an air inlet and a cyclone outlet, the air inlet facing the outside of the dust collecting shell, and the cyclone outlet facing the inside of the dust collecting shell; the guide assembly being arranged in the dust collecting shell, and the dust collecting shell being provided with an air outlet on the side of the guide assembly away from the air inlet duct, the guide assembly being opposite to the cyclone outlet and at least a portion of its structure being located in the air inlet duct, so that a cyclone flow path is formed between the guide assembly and the inner wall of the air inlet duct. Therefore, when applied to the cleaning device, the weight of the entire cleaning device can be reduced, the center of gravity of the entire device can be lowered, the weight can be avoided from being concentrated on the holding end of the cleaning device, and the user experience can be improved.

[0148] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
