Description

Technical Field

[0001] The present invention relates to the field of suction devices, and more particularly to a cleaning device. Background Art

[0002] With the development of technology, a variety of cleaning devices have emerged. For example, suction-type cleaning devices use the suction flow formed by a suction component to draw the airflow containing dirt into the device, and separate and collect the dirt such as liquid and / or solid in the suction flow inside the device, while the relatively clean airflow after separation is discharged outside the device.

[0003] Generally, a suction device includes a cover assembly and a barrel assembly. Relatively expensive parts such as a battery, a motor, and a circuit board are arranged inside the cover assembly, and the barrel assembly collects the separated liquid and / or solid dirt. The cover assembly is connected to the barrel assembly through a buckle. When it is necessary to clean the barrel assembly, the buckle is opened and the cover assembly is disassembled. This setting can prevent the motor, the circuit board, etc. from being contaminated by dust and water vapor. However, the weight is concentrated on the upper part, and the center of gravity is high during the moving process, making it easy to tip over. Moreover, due to the heavy weight of the cover assembly, the entire cover assembly needs to be lifted and placed on the side during the cleaning process, which is a laborious operation. Given the complex working environment of barrel suction, there may not necessarily be an empty space to place the cover assembly.

[0004] Currently, some vacuum cleaners are provided with a support member. When the cover assembly is flipped relative to the barrel assembly, the support member can be used to support the cover assembly. However, this requires a high strength for the support member, and there are still problems with poor stability. Summary of the Invention

[0137] To make the technical solutions and beneficial effects of the present invention more obvious and understandable, the following will be described in detail by way of specific embodiments. Among them, the drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

[0138] In the description of the present invention, the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of simplifying the description of the present invention, rather than indicating that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, that is, it cannot be understood as a limitation to the present invention.

[0139] In the present invention, the terms "first" and "second" are only used for the purpose of clear description and cannot be understood as the relative importance of the indicated features or the number of the indicated technical features. Therefore, the features defined with "first" and "second" can clearly include at least one such feature. In the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc.; the meaning of "several" is at least one, such as one, two, three, etc.; unless otherwise clearly and specifically defined.

[0140] In the present invention, unless otherwise clearly defined, terms such as "installation", "connection", "coupling", "fixing", "setting", etc. shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0141] In the present invention, unless otherwise clearly defined, when a first feature is "on", "above", "over", "upward" or "upon" a second feature, or "under", "below", "beneath" or "downward" of the second feature, the first feature and the second feature may be in direct contact, or the first feature and the second feature may be indirectly in contact through an intermediate medium. Moreover, when the first feature is "above", "over" or "upon" the second feature, the first feature may be directly above or obliquely above the second feature, or simply indicate that the horizontal height of the first feature is higher than the horizontal height of the second feature.

[0142] As Figures 1 to 4b shown, the cleaning device provided by the embodiment of the present disclosure includes: a barrel assembly 100, a base assembly 200 and a cover assembly 300. The base assembly 200 and the barrel assembly 100 are both located below the cover assembly 300. The base assembly 200 and the barrel assembly 100 can jointly serve as a base assembly for supporting the cover assembly 300. The barrel assembly 100 includes a first receiving cavity 101, the first receiving cavity 101 has a first opening 102, and the first receiving cavity 101 receives fluid, discharges fluid, collects dirt in the fluid, and discharges the dirt through the first opening 102. In some embodiments not shown in the present disclosure, the first opening 102 at the top of the barrel assembly 100 may not be used to receive fluid and / or discharge dirt. One or at least two through holes (not shown) may be provided on the side wall of the first receiving cavity 101 to receive fluid and introduce the fluid in the external space into the first receiving cavity 101, and / or discharge dirt through the through holes. Therefore, in the embodiments shown in the present disclosure, using the first opening 102 to receive fluid and discharge dirt not only improves the utilization rate of the first opening 102, realizes multiple functions with one opening, but also helps to increase the volume of the first receiving cavity 101 and facilitate the sealing of the first receiving cavity 101.

[0143] As Figure 5a shown, the base assembly 200 has a second receiving cavity 201 for accommodating a suction assembly 203. The suction assembly 203 is used to generate a suction flow (i.e., the above-mentioned fluid, generally an air flow) flowing through the first receiving cavity 101. The cover assembly 300 has an air flow channel communicating with the first receiving cavity 101. The air flow channel includes: as Figure 5c shown by the arrow in, a first air intake channel 340 for the suction flow flowing out of the first receiving cavity 101, and, as Figure 5a shown by the arrow in, a second air intake channel 320a for the air flow in the external space to enter the first receiving cavity 101. Generally, a hose (not shown) is connected to the cover assembly 300, and a suction nozzle (not shown) is connected to the end of the hose. The hose communicates with the second air intake channel 320a. Combining Figure 5a , Figure 5cand Figure 5d The working process of the cleaning device generally includes: the fluid in the external space is sucked into the hose in the form of a suction flow through the nozzle, and then enters the first accommodating cavity 101 through the second air inlet channel 320a via the hose. During the flow of the suction flow in the first accommodating cavity 101, under the action of centrifugal force, filtration, etc., some solid and / or liquid dirt in the suction flow will remain in the first accommodating cavity 101. Under the continuous operation of the suction assembly 203, the suction flow will enter the first air inlet channel 340 from the first accommodating cavity 101, then enter the inlet 203a of the suction assembly 203 from the first air inlet channel 340, and finally be discharged to the external environment through the outlet of the suction assembly 203 and the air outlet (not shown) on the base assembly 200.

[0144] Optionally, the suction assembly 203 includes a vacuum motor and an impeller. The impeller is connected to the output shaft of the vacuum motor, and the rotating output shaft can drive the impeller to rotate to form a suction flow. In addition to the suction assembly 203, a battery and / or a power interface can also be installed in the base assembly 200. Even more, accessories such as a hose and a nozzle can be stored in the base assembly 200.

[0145] The base assembly 200 is used to accommodate heavier parts such as the suction assembly 203, and the base assembly 200 is located below the cover assembly 300. There is no need to place the suction assembly 203 on the cover assembly 300, so the weight of the cover assembly 300 is reduced, and the center of gravity of the cleaning device is lowered, improving the stability of the device.

[0146] The cover assembly 300 is pivotally connected to the base assembly 200, the barrel assembly 100 is detachably connected to the base assembly 200, and the barrel assembly 100 is detachably connected to the cover assembly 300. The cover assembly 300 can cover the first opening 102 of the first accommodating cavity 101. It can be understood that after the cover assembly 300 covers the first opening 102, the cover assembly 300 and the first accommodating cavity 101 can jointly form a sealed space to ensure that the first accommodating cavity 101 is in a negative pressure state when the suction assembly 203 is working.

[0147] As Figures 1 to 3 shown, the barrel assembly 100 is located on the side of the base assembly 200. As Figure 4a and Figure 4bAs shown, the barrel assembly 100 can be detachably connected to the base assembly 200 in a substantially horizontal direction. That is to say, when the barrel assembly 100 needs to be withdrawn, the barrel assembly 100 can be withdrawn in a substantially horizontal direction, so that the barrel assembly 100 is separated from the base assembly 200, that is, the barrel assembly 100 is separated from the main body frame formed by the base assembly 200 and the cover assembly 300; when the barrel assembly 100 needs to be installed, the barrel assembly 100 can be horizontally moved in the opposite direction to facilitate the connection of the barrel assembly 100 to the main body frame. This detachable manner of the barrel assembly 100 and the base assembly 200 in a substantially horizontal direction does not require lifting the barrel assembly 100, which is more convenient for the user to operate.

[0148] Through the pivotal connection between the cover assembly 300 and the base assembly 200, the cover assembly 300 can at least include a closed position and an open position. As Figure 1 shown, the closed position means that the cover assembly 300 covers the first opening 102, as Figure 3 , Figure 4a and Figure 4b shown, the open position means that the cover assembly 300 does not cover the first opening 102. When the cover assembly 300 is in the open position, the user can conveniently replace the dust bag (also known as the filter bag) in the first accommodation cavity 101 through the first opening 102. In some application scenarios, the dust bag can also be replaced when the cover assembly 300 does not reach the open position. For example: in the position shown in Figure 2 , the user can hold the cover assembly 300 with one hand and replace the dust bag with the other hand. By using the detachable connections of the barrel assembly 100 to the base assembly 200 and the cover assembly 300 respectively, when the cover assembly 300 is in the open position, as Figure 4a and Figure 4b shown, the barrel assembly 100 can be separated from the base assembly 200. When there is water in the cleaning area or deep cleaning is required in the cleaning area, after the cleaning work is completed, by separating the barrel assembly 100 from the base assembly 200, the liquid or solid dirt can be poured from the first opening 102 to facilitate thorough cleaning of the first accommodation cavity 101.

[0149] Figure 2 Exemplarily shows a position of the cover assembly 300 between the closed position and the open position.

[0150] Since the barrel assembly 100 is detachably connected to the cover assembly 300 and the base assembly 200 respectively, when the barrel assembly 100 needs to be cleaned, as Figure 4a and Figure 4bAs shown, the barrel assembly 100 can be taken out alone, while the base assembly 200 remains connected to the cover assembly 300. Further, during the process of cleaning the barrel assembly 100, the base assembly 200 can be used to support the relatively light cover assembly 300, so that there is a place to place the cover assembly 300. Moreover, compared with the current cleaning equipment, this structure has lower requirements for support strength and better stability.

[0151] In the current cleaning equipment, the cover assembly is supported on the barrel assembly. Even when the cover assembly is in the open position, the barrel assembly cannot be separated from the cover assembly, and due to the occlusion of the cover assembly, the first opening of the barrel assembly cannot be fully opened. As Figure 4a and Figure 4b shown, the cover assembly 300 of the embodiment of the present disclosure does not need to be supported by the barrel assembly 100, and the barrel assembly 100 can be taken out alone. When the cover assembly 300 is in the open position, the first opening 102 of the barrel assembly 100 can be fully opened, which is more convenient for replacing the dust bag and cleaning the barrel assembly 100.

[0152] The cover assembly 300 can be switched between a closed position and an open position.

[0153] Figure 3 、 Figure 4a and Figure 4b Exemplarily, when the cover assembly 300 is in the open position, the cover assembly 300 is perpendicular to the base assembly 200, that is, the cover assembly 300 forms an angle of approximately 90° with the horizontal plane. This opening angle can fully open the first opening 102 of the first accommodation cavity 101, reduce the occlusion of the cover assembly 300 above the barrel assembly 100, and facilitate observing the internal situation of the first accommodation cavity 101 and replacing the dust bag located in the first accommodation cavity 101, etc. It can be understood that in other alternative implementation manners, when the cover assembly 300 is in the open position, on the basis of ensuring that the first opening 102 can be fully opened, the angle between the cover assembly 300 and the base assembly 200 can also be greater than 90°.

[0154] As Figure 3As shown, in some embodiments, when the cover assembly 300 is in the open position, the side wall 302 of the cover assembly 300 abuts against the top wall of the base assembly 200. This open position can reduce the strength requirements for the connection between the base assembly 200 and the cover assembly 300, and also utilize the self-structure of the reusable base assembly 200 to support the cover assembly 300, killing two birds with one stone. It can be understood that, in some alternative embodiments, when the cover assembly 300 is in the open position, the side wall 302 of the cover assembly 300 does not abut against the top wall of the base assembly 200. At this time, the structure at the connection between the cover assembly 300 and the base assembly 200 can be used to support the cover assembly 300. Since relatively heavy components such as the suction assembly 203 are located in the lower base assembly 200 and the cover assembly 300 is relatively light in weight, even without the support of the top wall of the base assembly 200 for the cover assembly 300, the connection reliability between the cover assembly 300 and the base assembly 200 can be effectively ensured.

[0155] As Figure 1 shown, when the cover assembly 300 covers the first opening 102, the barrel assembly 100 and the base assembly 200 are arranged side by side horizontally below the cover assembly 300.

[0156] In the embodiments of the present disclosure, the "detachable" connection includes at least one of magnetic connection and snap connection, but is not limited thereto.

[0157] In the embodiments shown in the present disclosure, a snap connection method is used to achieve detachability. As Figure 3 and Figure 8b shown, the cleaning device includes: a first locking component 310, and / or a second locking component 220; wherein, when the cover assembly 300 is in the closed position, the first locking component 310 is used to lock the connection between the cover assembly 300 and the barrel assembly 100, and the second locking component 220 is used to lock the connection between the base assembly 200 and the barrel assembly 100; when the cover assembly 300 is in the open position, the first locking component 310 is used to unlock the connection between the cover assembly 300 and the barrel assembly 100; the second locking component 220 is used to unlock the connection between the base assembly 200 and the barrel assembly 100.

[0158] Exemplarily, as Figure 5a and Figure 5b shown, the first locking component 310 includes: a first rotating shaft 311 and a first locking hook 312. The first rotating shaft 311 is connected to the cover assembly 300, and the first locking hook 312 is connected to the first rotating shaft 311 to pivotally connect to the cover assembly 300 through the first rotating shaft 311; when the cover assembly 300 is in the closed position, the first locking hook 312 is latched with the barrel assembly 100. As Figure 5bAs shown, a protruding boss 130 can be provided on the side wall of the barrel body in the barrel body assembly 100, and the bottom of the first locking hook 312 abuts against the bottom wall 131 of the boss 130. In this way, the barrel body assembly 100 can be fixed to the cover assembly 300. At the same time, the barrel body assembly 100 is limited between the first locking hook 312 and the base assembly 200, and the barrel body assembly 100 cannot be separated from the base assembly 200. Flip the first locking hook 312 upward. The first locking hook 312 rotates upward around the axis of the first rotating shaft 311, and the bottom of the first locking hook 312 is separated from the bottom wall 131 of the boss 130. Further, the first locking hook 312 is separated from the barrel body assembly 100. At this time, the cover assembly 300 can be rotated to the open position.

[0159] It can be understood that the boss 130 can be replaced by a flanging of the barrel body.

[0160] As Figure 5e shown, the first locking component 310 further includes: a first elastic member 314 and a brake assembly 350. The first elastic member 314 is installed on the cover assembly 300; the brake assembly 350 is respectively connected to the first locking hook 312 and the elastic member. When the cover assembly 300 is in the closed position, the first elastic member 314 provides a pre-tightening force to limit the separation of the first locking hook 312 from the barrel body assembly 100. Combining Figure 5b and Figure 5e shown, the part where the brake assembly 350 is connected to the first locking hook 312 is located between the bottom of the first locking hook 312 and the first rotating shaft 311. In this way, the pre-tightening force of the first elastic member 314 can pull the first locking hook 312 in the direction of the base assembly 200, thereby strengthening the locking force of the first locking hook 312 on the barrel body assembly 100 and also reducing the risk of the first locking hook 312 accidentally disengaging from the boss 130.

[0161] Exemplarily, the first elastic member 314 includes a spring or a spring piece.

[0162] Exemplarily, as Figure 5b shown, the first locking hook 312 has a locking groove 313, and one end of the brake assembly 350 abuts against the groove wall of the locking groove 313. In addition, ribs can be used instead of the locking groove 313, and the brake assembly 350 realizes the pulling of the first locking hook 312 by abutting against the ribs.

[0163] Non-limitingly, the end of the brake assembly 350 connected to the locking groove 313 is T-shaped.

[0164] The cleaning device further includes: a rotating member 210, and the rotating member 210 is respectively connected to the base assembly 200 and the cover assembly 300. In the embodiment shown in the present disclosure, combining Figure 6a and Figure 6cAs shown, the rotating member 210 is fixedly connected to the base assembly 200, and the cover assembly 300 is rotatably connected to the rotating member 210. When the cover assembly 300 flips relative to the base assembly 200 under an external force, the cover assembly 300 rotates along the outer circumference of the rotating member 210 to achieve the pivotal connection between the cover assembly 300 and the base assembly 200.

[0165] In some embodiments not shown in the present disclosure, the manner of using the rotating member to achieve the pivotal connection between the cover assembly 300 and the base assembly 200 further includes: the rotating member is rotatably mounted on the base assembly 200, the rotating member is fixedly connected to the cover assembly 300, and when the cover assembly 300 flips relative to the base assembly 200 under an external force, the rotating member and the cover assembly 300 rotate simultaneously relative to the axis of the rotating member 210.

[0166] In the embodiments shown in the present disclosure, in combination with Figure 5e , Figure 6b , Figure 6c and Figure 6d As shown, the rotating member 210 has a limit pin hole 212a; the brake assembly 350 includes: a brake wire 351 and a limit pin 352, one end of the brake wire 351 is connected to the first locking hook 312; the limit pin 352 is respectively connected to the other end of the brake wire 351 and the first elastic member 314. The pre-tightening force provided by the first elastic member 314 can not only strengthen the connection between the first locking hook 312 and the barrel assembly 100, but also push the limit pin 352 into the limit pin hole 212a to achieve the locking between the cover assembly 300 and the base assembly 200. When the first locking hook 312 is flipped upward by an external force, by using the brake wire 351 and the first elastic member 314, the separation of the first locking hook 312 from the barrel assembly 100 and the separation of the limit pin 352 from the limit pin hole 212a can be achieved simultaneously.

[0167] Generally, as Figure 6b shown, the rotating member 210 is circumferentially provided with at least two spaced-apart limit pin holes 212a. When an external force is applied to trigger the first locking hook 312, the cover assembly 300 is disengaged from the closed position, the first locking hook 312 drives the brake wire 351 to move towards the barrel assembly 100, the brake wire 351 drives the limit pin 352 to move in the same direction, the limit pin 352 is separated from the current limit pin hole 212a, and at the same time, the limit pin 352 drives the first elastic member 314 to deform. When the cover assembly 300 is further reversely rotated upward, as Figure 7b shown, the limit pin 352 abuts against the side wall of the rotating member 210 between two limit pin holes 212a and rotates along the side wall, and the rotation path can refer to Figure 6dThe double arrow in the middle. Therefore, the first elastic member 314 is always subjected to an external force, but the limit pin 352 does not prevent the rotation of the rotating member 210, and the cover assembly 300 can smoothly change from the closed position to the open position. When the limit pin 352 reaches the next limit pin hole 212a, the limit pin 352 is inserted into the limit pin hole 212a again, the first elastic member 314 resumes deformation, and provides a pre-tightening force to keep the limit pin 352 in the limit pin hole 212a, and the cover assembly 300 cannot continue to rotate. At this time, the cover assembly 300 is in the open position.

[0168] Therefore, the limit pin 352 is inserted into the limit pin hole 212a under the action of the pre-tightening force provided by the first elastic member 314. When in the closed position and the open position, it can limit the rotation of the cover assembly 300 and keep the cover assembly 300 in the closed position or the open position. Furthermore, when the user replaces the dust bag or cleans the barrel assembly when the cover assembly 300 is in the open position, there is no need to hold the cover assembly 300 by hand; when the first locking hook 312 is flipped by an external force, it can overcome the pre-tightening force of the first elastic member 314, so that the first elastic member 314 is in a deformed state, so as to disengage the limit pin 352 from the limit pin hole 212a. Furthermore, the cover assembly 300 can enter the switching process between the closed position and the open position.

[0169] The distance between the two limit pin holes 212a on the rotating member 210 is related to the flipping angle of the cover assembly 300. Generally, the larger the distance between the two limit pin holes 212a, the larger the flipping angle of the cover assembly 300 in the open position; conversely, the smaller the distance between the two limit pin holes 212a, the smaller the flipping angle of the cover assembly 300 in the open position. And the distance between the two limit pin holes 212a is related to the outer diameter (referring to the external diameter) of the rotating member 210. The larger the outer diameter of the rotating member 210, the relatively larger the maximum distance between the two limit pin holes 212a. Conversely, the smaller the outer diameter of the rotating member 210, the relatively smaller the maximum distance between the two limit pin holes 212a.

[0170] The axes of the two limit pin holes 212a intersect with the axis of the rotating member 210 at the same point. The larger the angle between the axes of the two limit pin holes 212a, the greater the circumferential distance between the two limit pin holes 212a on the rotating member 210, and thus the larger the flipping angle of the cover assembly 300 in the open position; conversely, the smaller the angle between the axes of the two limit pin holes 212a, the smaller the flipping angle of the cover assembly 300 in the open position.

[0171] Such as Figure 6aAs shown, the rotating member 210 protrudes from the base assembly 200 and is located at the edge of the base assembly 200 away from the barrel assembly 100. The rotating member 210 and the barrel assembly 100 are respectively located at two opposite edges of the base assembly 200, and the farther the rotating member 210 is from the barrel assembly 100, the less likely the lid assembly 300 is to block the first opening 102 when in the open position.

[0172] In the embodiment shown in the present disclosure, the included angle between the axes of the two limit pin holes 212a is 90°. Further, the flipping angle of the lid assembly 300 when in the open position relative to the closed position is 90°.

[0173] It can be understood that if the number of limit pin holes 212a is three circumferentially spaced around the rotating member 210, the lid assembly 300 can stay in three positions, which can be Figure 1 the closed position shown, Figure 3 the open position shown, and Figure 2 a certain position between the closed position and the open position shown (or, a certain position where the opening angle of the lid assembly 300 is greater than Figure 3 the 90° shown). If the number of limit pin holes 212a is more than three, the lid assembly 300 can stay in more than three positions.

[0174] In the closed position of the lid assembly 300, the first locking component 310 can be used to achieve double locking and horizontal locking between the lid assembly 300 and the barrel assembly 100, as well as between the lid assembly 300 and the base assembly 200. In the open position of the lid assembly 300, the cooperation of the first locking component 310 and the rotating member 210 restricts the rotation of the lid assembly 300 relative to the base assembly 200, which can improve the connection reliability between the lid assembly 300 and the base assembly 200 and reduce the risk of accidental tipping of the lid assembly 300.

[0175] Optionally, as shown in combination with Figure 6a 、 Figure 6b and Figure 6e the rotating member 210 includes: a second rotating shaft 211 and a bushing 212. The second rotating shaft 211 is attached to the base assembly 200. The bushing 212 is sleeved outside the second rotating shaft 211 and is rotatably connected to the lid assembly 300. At least a part of the bushing 212 is a hollow part 212b, and the limit pin holes 212a are formed in the hollow part 212b.

[0176] Exemplarily, the bushing 212 is connected to the second rotating shaft 211 by fasteners such as screws or bolts, and the mechanical strength of the bushing 212 is greater than that of the second rotating shaft 211. This structure of the rotating member 210 can facilitate the formation of the second rotating shaft 211 by injection molding, and then ensure the overall strength of the rotating member 210 by adding the bushing 212 with higher strength. The material of the bushing 212 includes but is not limited to: metal, polyoxymethylene (POM, polyformaldehyde).

[0177] As Figure 8a and Figure 8b shown, the base assembly 200 includes a first groove 221 having a second opening 222, and the first groove 221 is used to accommodate the second latch assembly 220; the second latch assembly 220 includes: a second latch hook 223 and a second elastic member (not shown), and two ends of the second elastic member are respectively connected to the inner wall of the first groove 221 and the second latch hook 223; the barrel assembly 100 has a second groove 103; when the cover assembly 300 is in the closed position, as Figure 8c shown, the second elastic member generates an elastic deformation force under the pressure of the cover assembly 300 to drive the second latch hook 223 to enter the second groove 103 through the opening of the second groove 103 and latch with the groove wall 103a of the second groove 103, strengthening the connection between the barrel assembly 100 and the base assembly 200. When the cover assembly 300 is in the open position, as Figure 8b shown, the second elastic member releases the elastic deformation force, and the elastic deformation force of the second elastic member drives the second latch hook 223 to move upward, and the second latch hook 223 is separated from the groove wall 103a of the second groove 103. At this time, by pulling the barrel assembly 100 laterally, the second latch hook 223 can be disengaged from the opening of the second groove 103, realizing the separation of the barrel assembly 100 from the base assembly 200.

[0178] Exemplarily, the second elastic member includes a spring or a spring sheet.

[0179] Optionally, as combined with Figure 4a and Figure 4b shown, the boss 130 and the second groove 103 are respectively located on opposite sides of the barrel assembly 100. In this way, by using the latching of the first latch hook 312 in the first latch assembly 310 with the boss 130 and the latching of the second latch hook 223 in the second latch assembly 220 with the inner wall of the second groove 103, the barrel assembly 100 can be limited from opposite sides of the barrel assembly 100, reducing the risk of the barrel assembly 100 disengaging during the use of the cleaning device or when the cover assembly 300 is in the closed position.

[0180] Optionally, the cover assembly 300 is substantially overlapped with the base assembly (i.e., the combination of the barrel assembly 100 and the base frame assembly 200) in the vertical direction, and the projection is substantially rectangular. The axes in the length direction of the rectangular projection coincide approximately with the perpendicular lines at the midpoints of the first locking assembly 310 and the rotating member 210 respectively. The rotating member 210 is used to achieve the pivotal connection between the cover assembly 300 and the base frame assembly 200, and the first locking assembly 310 is used for the detachable connection between the cover assembly 300 and the barrel assembly 100. This connection method can strengthen the structures of the three components: the barrel assembly 100, the base frame assembly 200, and the cover assembly 300.

[0181] As Figure 4a and Figure 4b shown, in some embodiments, the base frame assembly 200 includes: a second housing 230a and guiding and limiting arms 231 protruding from both sides of the second housing 230a towards the barrel assembly 100 respectively. The space between the two guiding and limiting arms 231 is used to accommodate the barrel assembly 100. The two guiding and limiting arms 231 can not only guide the alignment connection between the barrel assembly 100 and the base frame assembly 200, but also use the space between the two guiding and limiting arms 231 to limit the barrel assembly 100 in the horizontal direction, ensuring the reliability of the connection of the barrel assembly 100. Exemplarily, as Figure 4a shown, the guiding and limiting arm 231 has: a first limiting surface 231a for limiting the barrel assembly 100 in the horizontal direction and guiding the alignment connection between the barrel assembly 100 and the base frame assembly 200, and a second limiting surface 231b for limiting the barrel assembly 100 in the vertical direction; as Figure 4b shown, the barrel assembly 100 includes a third limiting surface 105b docked with the first limiting surface 231a, and a fourth limiting surface 105a docked with the second limiting surface 231b.

[0182] Optionally, the barrel assembly 100 further has a third groove 104, and the base frame assembly 200 includes: a support protrusion 232 protruding from the second housing 230a towards the barrel assembly 100, and the support protrusion 232 is located between the two guiding and limiting arms 231; the support protrusion 232 can be inserted into the third groove 104. By using the connection between the third groove 104 and the support protrusion 232, the connection between the barrel assembly 100 and the base frame assembly 200 can be further strengthened, and the risk of the barrel assembly 100 coming out can be further reduced.

[0183] Optionally, as Figures 4b to 4d shown, the base frame assembly 200 further includes an elastic protrusion 253 and a control member 250 for controlling the protrusion or retraction of the elastic protrusion 253, and the barrel assembly 100 has a fourth groove 106. Figure 4cThe elastic protrusion 253 and the control member 250 are exemplarily shown to be located on one of the guide limit arms 231. When the control member 250 controls the elastic protrusion 253 to protrude, the elastic protrusion 253 is located in the fourth groove 106, and the separation of the barrel assembly 100 and the base assembly 200 can be limited by the abutment between the elastic protrusion 253 and the inner wall of the fourth groove 106. When the control member 250 controls the elastic protrusion 253 to retract, the elastic protrusion 253 escapes from the fourth groove 106 and separates from the inner wall of the fourth groove 106. When the cover assembly 300 is in the open position, the first locking assembly 310 cannot lock the cover assembly 300 and the barrel assembly 100, and the second locking assembly 220 cannot lock the base assembly 200 and the barrel assembly. In other words, when the cover assembly 300 is in the open position, the locking of the barrel assembly 100 by the first locking assembly 310 and the second locking assembly 220 fails, and the barrel assembly 100 is easy to lose control. By utilizing the cooperation between the elastic protrusion 253 and the fourth groove 106, the barrel body assembly 100 can be temporarily fixed when the cover assembly 300 is in the open position, and the barrel body assembly 100 can be temporarily fixed to the base assembly 200. When the user needs to separate the barrel body assembly 100, the control member 250 is operated to separate the barrel body assembly 100.

[0184] The control member 250 controls the elastic protrusion 253 to protrude or retract, including: Figure 4d As shown, the control member 250 includes a pedal 251, a linkage member 252 linked to the pedal 251, and a third elastic member 254. An elastic protrusion 253 is formed on the linkage member 252, the base assembly 200 has a hollow space for accommodating the linkage member 252, the linkage member 252 abuts against the pedal 251, and one end of the third elastic member 254 is connected to the linkage member 252, and the other end is connected to the inner wall of the hollow space for accommodating the linkage member 252. When the pedal 251 is not stepped on, the elastic protrusion 253 extends out of the hollow space and is located in the fourth groove 106 to ensure that when the cover assembly 300 is in the open position, the barrel assembly 100 can also be temporarily fixed, and the pre-tightening force of the third elastic member 254 can keep the elastic protrusion 253 in a protruding state to ensure the reliability of the connection between the barrel assembly 100 and the base assembly 200. When the pedal 251 is stepped on, the external force of the step overcomes the pre-tightening force of the third elastic member 254, and the pedal 251 lifts the linkage member 252 upward, and the linkage member 252 retracts upward and toward the inside of the hollow space under the guidance of the inclined surface 253a on the elastic protrusion 253, that is, the elastic protrusion 253 retracts, and the elastic protrusion 253 is separated from the groove wall of the fourth groove 106, and the barrel assembly 100 can be separated from the base assembly 200. After the external force acting on the pedal 251 disappears, the linkage member 252 moves downward and resets under the gravity, and the elastic protrusion 253 also resumes the protruding state again under the action of the third elastic member 254, and the pedal 251 moves downward and resets under the gravity of the linkage member 252, so that the linkage member 252, the third elastic member 254 and the pedal 251 are all reset.

[0185] The manner in which the control member 250 controls the protrusion or retraction of the elastic protrusion 253 may also include, but is not limited to: removing the pedal 251 and the third elastic member 254, and the user can manually push the linkage member 252 to achieve the protrusion of the elastic protrusion 253, and manually pull back the linkage member 252 to achieve the retraction of the elastic protrusion 253.

[0186] The third elastic member 254 may be a spring, but is not limited thereto.

[0187] Such as Figures 2 to 4b and Figure 7a As shown in

[0188] Since the suction assembly 203 is disposed in the lower base assembly 200, the cover assembly 300 and the lower base assembly 200 need not only electrical connection, but also air pipeline connection. By providing the telescopic pipe 330, the risk of air leakage is reduced, and the rotation of the cover assembly 300 is not affected. The circuits involved in the electrical connection between the cover assembly 300 and the base assembly 200 include, but are not limited to, at least one of the following: a full-dust sensing circuit disposed inside the barrel assembly 100, a circuit for controlling the rotation of the roller brush at the hose nozzle disposed on the cover assembly 300, and a self-cleaning drive circuit for the filter assembly disposed inside the cover assembly 300.

[0189] Optionally, the telescopic pipe 330 includes a corrugated pipe or a coiled pipe. In addition, the telescopic pipe 330 may also be other pipe fittings that are elastic and deformable, but do not affect ventilation after deformation. The deformation of the telescopic pipe 330 includes, but is not limited to, at least one of the following: compression, tension, or bending. For example, as Figure 2 shown, when the cover assembly 300 is in the open position, the telescopic pipe 330 will bend approximately 90°. At the bent portion of the telescopic pipe 330, the inner wall of the bent inner diameter of the telescopic pipe 330 is compressed, and the outer wall of the bent outer diameter of the telescopic pipe 330 is stretched to adapt to the opening and flipping of the cover assembly 300. When the cover assembly 300 flips from the open position to the closed position, the deformation of the telescopic pipe 330 is restored.

[0190] Such as Figure 5c and Figure 5eAs shown, the first intake passage 340 includes an upstream passage 340a and a downstream passage 340b. The upstream passage 340a is docked with the first accommodation chamber 101. The downstream passage 340b is connected to the upstream passage 340a and the telescopic tube 330 respectively. The suction flow in the first accommodation chamber 101 first enters the upstream passage 340a and then enters the downstream passage 340b from the upstream passage 340a. The cleaning device further includes a first filter assembly 341 and / or a second filter assembly 342. The first filter assembly 341 is located at the entrance of the upstream passage 340a. The second filter assembly 342 is located at the exit of the upstream passage 340a and between the upstream passage 340a and the downstream passage 340b.

[0191] The first filter assembly 341 or / and the second filter assembly 342 form a filter assembly for filtering the suction flow passing through the first intake passage 340 (i.e., the suction flow flowing out of the first accommodation chamber 101).

[0192] Without limitation, the first filter assembly 341 may be a Hepa assembly, and the second filter assembly 342 may be a grille structure. In the embodiment shown in the present disclosure, the cleaning device has both the first filter assembly 341 and the second filter assembly 342.

[0193] Setting the first filter assembly 341 and the second filter assembly 342 in the upstream passage 340a can further filter the dirt in the passing suction flow and reduce the influence of the dirt on the suction assembly 203 in the downstream path of the first intake passage 340.

[0194] The first filter assembly 341 and the second filter assembly 342 filter the suction flow at different positions where the fluid flows through. Among them, the first filter assembly 341 preliminarily filters the upstream suction flow, and the second filter assembly 342 can further filter the suction flow to improve the filtering effect. The first intake passage 340 extends substantially in the horizontal direction.

[0195] Optionally, the number of the downstream passages 340b is two, and each downstream passage 340b is respectively connected to a telescopic tube 330. The telescopic tube 330 is arranged downstream of the first intake passage 340, and thus the telescopic tube 330 is also downstream of the filter assembly. Therefore, the suction flow entering the telescopic tube 330 is a relatively clean airflow after filtration, which can reduce the adhesion of dirt on the inner wall of the telescopic tube 330, and the two telescopic tubes 330 can also improve the separation efficiency of the dirt in the suction flow.

[0196] As Figure 5e shown, the two downstream passages 340b can also save space. The intake pipe 320 is placed in the space between the two downstream passages 340b, which improves the utilization rate of the internal space of the cover assembly 300 and makes the structure of the cleaning device more compact.

[0197] AsFigure 5c and Figure 5d As shown by the arrow directions in Figure 5d , the flow path of the suction flow flowing out of the first accommodation chamber 101 sequentially includes: an upstream channel 340a, a downstream channel 340b, a telescopic tube 330, and a suction assembly 203.

[0198] Without limitation, the first intake channel 340 may be formed by splicing two different shells of the cover assembly 300, or the first intake channel 340 may be formed by a pipeline embedded inside the cover assembly 300.

[0199] As Figure 9a shown, the cover assembly 300 includes: a first shell 371 and an intake pipe 320. As Figure 5e and Figure 8a shown, the intake pipe 320 includes: an inlet portion 321 located in the external space, an outlet portion 322 protruding from the first shell 371 towards the first accommodation chamber 101, and an intermediate portion 323 located inside the first shell 371; the inlet portion 321 is used to connect a hose with a nozzle, and the intake pipe 320 defines and forms a second intake channel 320a.

[0200] It can be understood that if the side wall of the first accommodation chamber 101 has a through hole for receiving fluid, the intake pipe 320 may not be provided, and connecting a hose with a nozzle to this through hole can also introduce the fluid in the external space into the first accommodation chamber 101.

[0201] As Figure 5a shown, the outlet 322a of the second intake channel 320a is located on the side wall of the outlet portion 322, and the outlet 322a of the second intake channel 320a does not face the inlet of the first intake channel 340. The outlet 322a of the second intake channel 320a has a side opening and does not face the inlet of the first intake channel 340, which can extend the movement distance and residence time of the suction flow in the first accommodation chamber 101, and thus better achieve the separation of dirt and the suction flow.

[0202] Figure 5a In the implementation shown, the inlet of the first intake channel 340 (i.e., the position where the first filter assembly 341 is located) is approximately on the left side of the first accommodation chamber 101, while the outlet 322a of the second intake channel 320a faces forward. Here, "left" and "forward" are both relative Figure 5a to the relative direction when showing the cleaning device. Among them, Figure 5a is Figure 1 a cross-sectional view of the cleaning device shown approximately from the a perspective; Figure 5c is Figure 1 a cross-sectional view of the cleaning device shown approximately from the b perspective, Figure 5d is Figure 1 a cross-sectional view of the cleaning device shown approximately from the c perspective, Figure 5e isFigure 1 Partial structural schematic diagram from a roughly top-down perspective.

[0203] As Figure 1 , Figure 5d , Figure 6c , Figure 9a and Figure 9b As shown in Figure 1 , Figure 5d , Figure 6c , Figure 9a , and Figure 9b , the top of the cover assembly 300 has a storage groove 301 for accommodating a hose. The side of the storage groove 301 facing the hose has a third opening 301a through which the hose can pass.

[0204] The hose can be directly coiled in the storage groove 301 without being detached from the cover assembly 300, facilitating the next use of the cleaning device. The third opening 301a facilitates the entry of the hose into the storage groove 301.

[0205] Without limitation, the storage groove 301 is generally U-shaped.

[0206] Generally, the tube wall of the hose has a certain hardness and can be bent. Without external pressure, the hose remains in a long strip shape when placed randomly. The hardness of the hose tube wall can come from the metal wire wound inside the hose, and the metal wire can be a steel wire, but is not limited thereto.

[0207] Optionally, the depth of the storage groove 301 is greater than or equal to the outer diameter of the hose, so as to reduce the protrusion of the hose from the cover assembly 300 when the hose is stored in the storage groove 301, and better ensure the integrity of the cover assembly 300.

[0208] As Figure 1 , Figure 4b , Figure 5c , Figure 5d , Figure 6c , Figure 9a and Figure 9b As shown in Figure 1 , Figure 4b , Figure 5c , Figure 5d , Figure 6c , Figure 9a , and Figure 9b , in some alternative embodiments, the cleaning device further includes: a first handle 360 located at the top of the cover assembly 300, and the storage groove 301 is distributed around the first handle 360.

[0209] Grasping the first handle 360 facilitates picking up the entire cleaning device and can also be used to rotate the cover assembly 300 using the first handle 360.

[0210] The top of the first handle 360 is substantially flush with the top of the cover assembly 300 to ensure the integrity of the cover assembly 300.

[0211] As Figures 9c to 9f shown, the cover assembly 300 further has: a first fixing position 372 and a second fixing position (not shown); the cleaning device further includes: a fixing rib 391 installed at the first fixing position 372 and detachably connected to the second fixing position. Among them, as Figure 9c andFigure 9d As shown, when the fixing rib 391 is subjected to an external force, it will elongate and be in an elongated state. As Figure 9e and Figure 9f shown, after the external force acting on the fixing rib 391 is withdrawn, the fixing rib 391 will retract and reset to be in a retracted state. After the fixing rib 391 elongates, it can cross the receiving groove 301 and extend to the second fixing position. Moreover, when the fixing rib 391 crosses the receiving groove 301, the hose is located between the fixing rib 391 and the bottom wall of the receiving groove 301.

[0212] Exemplarily, the first fixing position 372 and the second fixing position can be located on opposite sides of the cover assembly 300.

[0213] After the hose is placed in the receiving groove 301, as Figure 9c and Figure 9d shown, the fixing rib 391 can be pulled along the path of the arrow shown in Figure 9b to be fixed to the second fixing position, so as to prevent the hose from slipping out of the receiving groove 301 and ensure the reliability of the hose fixed in the receiving groove 301. When the hose needs to be used, as Figure 9e and Figure 9f shown, the fixing rib 391 is separated from the second fixing position, and the fixing rib 391 can automatically contract and reset.

[0214] As Figures 9c to 9f shown, the first fixing position includes: two guide rods 372a, two sliders 372b slidably connected to the guide rods 372a, and a fourth elastic member 372c with both ends respectively connected to the two sliders 372b. Among them, the fixing rib 391 passes through the two sliders 372b so that the fixing rib 391 can move relative to the sliders 372b, and the two guide rods 372a both pass through the two sliders 372b to realize the sliding of the sliders 372b on the guide rods 372a. When the fixing rib 391 is subjected to an external force, as Figure 9c and Figure 9d shown, the fixing rib 391 drives the two sliders 372b to slide along the guide rods 372a and approach each other. The approaching sliders 372b will compress the fourth elastic member 372c located between the two sliders 372b, and the fourth elastic member 372c generates elastic deformation. The part of the fixing rib 391 located between the two sliders 372b is shortened, and further the fixing rib 391 can be stretched to cross the receiving groove 301 to the second fixing position. After the external force is withdrawn, as Figure 9e and Figure 9fAs shown, under the elastic restoring force of the fourth elastic member 372c, the two sliders 372b slide along the guide rod 372a in a direction away from each other, and the length of the fixing rib 391 between the two sliders 372b moving away from each other increases. As a result, the fixing rib 391 can retract and reset. By using structures such as the guide rod 372a, the slider 372b, and the fourth elastic member 372c, the scalability of the fixing rib 391 can be improved, and the fixing rib 391 can automatically retract and reset, making it convenient and reliable to use.

[0215] The number of the guide rods 372a and the sliders 372b is not limited to two, and can also be independently set to three or more respectively. The number of the guide rods 372a can also be one.

[0216] In an embodiment not shown in the present disclosure, the guide rod 372a, the slider 372b, and the fourth elastic member 372c can be cancelled. That is to say, the scalability of the fixing rib 391 is not realized by using the first fixing position, but by using the material characteristics of the fixing rib 391. For example: the fixing rib 391 has elasticity, and the elongation or retraction is realized by the elastic deformation of the fixing rib 391, and the purpose of fixing the hose can also be achieved.

[0217] In the embodiments shown in the present disclosure, the scalability of the fixing rib 391 is realized by using the first fixing position. Furthermore, the material of the fixing rib 391 can be an elastic material or not.

[0218] Without limitation, the fixing rib 391 is a rubber rib.

[0219] As Figures 9a to 9f shown, the cleaning device further includes: a hook 390, the hook 390 is connected to the fixing rib 391, and the hook 390 has a card slot 392 for connecting to the second fixing position.

[0220] The hook 390 makes it more convenient to pull the fixing rib 391. After the fixing rib 391 is pulled to the second fixing position, the hook 390 is hooked on the second fixing position to maintain the extended state of the fixing rib 391, thereby ensuring the fixing effect of the fixing rib 391 on the hose.

[0221] Exemplarily, the second fixing position can include a rod, and the outer diameter of the rod can be smaller than the width of the card slot 392 so that the card slot 392 can be stuck on the rod to realize the fixing of the fixing rib 391.

[0222] As Figure 9a shown, in some alternative embodiments, the cover assembly 300 includes: a wire storage cavity 381, the cavity wall of the wire storage cavity 381 is connected to the fixing rib 391, a part of the fixing rib 391 is located inside the wire storage cavity 381, and the other part is located outside the wire storage cavity 381, and the part of the fixing rib 391 located outside the wire storage cavity 381 is used to receive an external force.

[0223] The take-up cavity 381 is used to hide the fixing rib 391. Optionally, the part of the fixing rib 391 located outside the take-up cavity 381 is surrounded by the hook 390. This way can reduce the exposure of the fixing rib 391, thereby reducing the corrosion and damage of the fixing rib 391 by the external space and improving the service life of the fixing rib 391.

[0224] The cavity wall of the storage cavity can be used to fix the guide rod 372a. When the fixing rib 391 is made telescopic by using the elasticity of its own material, the cavity wall of the storage cavity can be used as another optional structure of the first fixing position 372. At this time, the cavity wall of the storage cavity can have features such as hook parts and through holes for fixing the fixing rib 372.

[0225] Combined Figure 9a and Figure 9b As shown, one implementation of the take-up cavity 381 includes: being jointly formed by the cover base 370 of the cover assembly 300 and the third housing 380. The cover base 370 is the part of the cover assembly 300 that is connected to the machine base assembly 200 and the barrel assembly 100, and is also the part with the first air inlet channel 340 and the second air inlet channel 320a. Therefore, the take-up cavity 381 is not communicated with the first accommodation cavity 101 or the air flow channel, which can also reduce the corrosion of the fixing rib 391 by the suction flow and further protect the fixing rib 391.

[0226] In some alternative embodiments, the position of the cover base 370 opposite to the filter assembly has an operation window (not shown). As Figure 1 shown, the cover assembly 300 further includes a cover body 373. The cover body 373 is movably connected to the cover base 370 and can cover the operation window. When the filter assembly needs to be replaced, the cover body 373 can be moved to expose the operation window, and the filter assembly can be replaced through the operation window.

[0227] The cover body 373 being movably connected to the cover base 370 includes: the cover body 373 is pivotally connected to the cover base 370, or the cover body 373 is detachably connected to the cover base 370.

[0228] Optionally, as Figures 2 to 4b shown, the outline of the cover assembly 300 is basically in the shape of a cuboid, and the filter assembly is located inside the cover base 370. By arranging the filter assembly inside the cover assembly 300, when the cover assembly 300 is in the open position, it will not block the first opening 102 due to the excessive protrusion of the filter assembly, which is more conducive to the complete opening of the first opening 102.

[0229] As Figures 2 to 4a , and Figure 6aAs shown, in some alternative embodiments, the bucket assembly 100 includes: a bucket body 110 and a dust bag holder 120. The bucket body 110 defines a first receiving cavity 101. The dust bag holder 120 is connected to the cavity wall of the first receiving cavity 101. The dust bag holder 120 is used for installing a dust bag, and the dust bag inlet can be docked with the outlet portion 322 of the intake pipe 320 to communicate the inlet of the intake pipe 320 with the inlet of the dust bag.

[0230] The air flow flowing out of the second intake passage 320a will enter the dust bag through the outlet portion 322. The dust bag can filter out some solid dirt in the suction flow, and the filtered suction flow will enter the first intake passage 340. In this way, when cleaning the bucket assembly 100, only the dust bag needs to be replaced, which is convenient for cleaning.

[0231] As Figure 5d and Figure 8a As shown, optionally, the inlet 203a of the suction assembly 203 faces downward, and there is a gap 204 between the inlet 203a and the bottom wall of the second receiving cavity 201.

[0232] When there is water in the cleaning area, there may be liquid in the fluid sucked by the suction nozzle. During the process of the fluid entering the first receiving cavity 101 through the second intake passage 320a, water vapor separation occurs. Part of the liquid will fall to the bottom of the first receiving cavity 101, and the other part will flow with the fluid through the HEPA assembly to the inlet 203a of the suction assembly 203. Since the inlet 203a of the suction assembly 203 is set at a certain distance from the bottom surface, it is beneficial to keep the liquid staying below the inlet 203a of the suction assembly 203 first in the case where the fluid flowing out of the telescopic pipe 330 contains liquid, avoiding the fluid containing liquid being directly sucked into the suction assembly 203, which has a protective effect on the suction assembly 203.

[0233] It can be understood that when there is water in the cleaning area, the dust bag can be not installed.

[0234] As Figures 1 to 5a As shown, optionally, the bucket assembly 100 further includes: a first roller 150 and a second handle 140. The first roller 150 is located on the bottom wall of the first receiving cavity 101. The second handle 140 is located on the side wall of the first receiving cavity 101, and the second handle 140 is pivotally connected to the bucket assembly 100.

[0235] By using the first roller 150 and the second handle 140, the bucket assembly 100 or the entire cleaning device can be conveniently moved.

[0236] As Figures 1 to 5a As shown, optionally, the base assembly 200 includes: a storage box 230 and a second roller 240. The storage box 230 has a second receiving cavity 201. The second roller 240 is located at the bottom of the storage box 230, and the bottom of the second roller 240 and the bottom of the first roller 150 are on the same horizontal plane.

[0237] The cooperation between the second roller 240 and the first roller 150 can further facilitate the movement of the cleaning device.

[0238] As Figure 4a shown, the storage box 230 can be formed with an avoidance space 202 for the telescopic tube 330 to pass through, and the above-mentioned second accommodation cavity 201, or the storage box 230 also has an accessory cavity for accommodating accessories.

[0239] As Figure 4a and Figure 5d shown, the avoidance space 202 is used to accommodate the telescopic tube 330. When the cover assembly 300 is in the closed position, the telescopic tube 330 can be retracted into the avoidance space 202. One end of the telescopic tube 330 is connected to the cover assembly 300, and the other end is connected to the bottom inner wall of the avoidance space 202.

[0240] As Figure 5d shown, the telescopic tube 330 and the suction assembly 203 are arranged side by side in a substantially horizontal direction (i.e., Figure 5d the a-a direction in Figure 5d ), and are perpendicular to the horizontal side-by-side direction of the barrel assembly 100 and the base assembly 200 (i.e., Figure 5d the b-b direction in

[0241] As Figure 5d shown, in the embodiment shown in the present disclosure, the two telescopic tubes 330 and the suction assembly 203 are both arranged in the a-a direction, and the suction assembly 203 is located between the two telescopic tubes 330.

[0242] As Figure 10 and Figure 11 shown, the inner wall of the telescopic tube 330 has concave and convex patterns to form a sound-absorbing structure 334.

[0243] The concave and convex patterns can be used to absorb noise and reduce the noise of the cleaning device. Moreover, the telescopic tube 330 has a certain elasticity. When the internal and external pressures of the telescopic tube 330 change, such as suddenly turning on or off, the telescopic tube 330 can adjust the pressure by using its own elastic deformation, further reducing the noise. Moreover, when elastic deformation occurs, the dust adhering to the inner wall of the telescopic tube 330 can also be shaken off.

[0244] Exemplarily, the sound-absorbing structure 334 includes: a plurality of annular corrugations axially distributed along the telescopic tube 330, and / or spiral grooves axially distributed along the telescopic tube 330. Figure 11 Exemplarily shown is a sound-absorbing structure 334 with spiral grooves 334a on the inner wall of the telescopic tube 330.

[0245] Such as Figure 10 and Figure 11 As shown, the cleaning device further includes: a joint 331, and both ends of the telescopic tube 330 are respectively connected to the cover assembly 300 and the base assembly 200 through the joint 331; the joint 331 has a receiving groove 335 for receiving a sealing structure 336, and the sealing structure 336 is used to achieve sealing at the connection between the joint 331 and the cover assembly 300, and / or achieve sealing at the connection between the joint 331 and the base assembly 200.

[0246] Optionally, as Figure 10 and Figure 11 As shown, the joint 331 has an ear 332 extending radially along the joint 331, and the ear 332 has a mounting hole 333 for fasteners such as screws and bolts to pass through to respectively achieve the connection between the joint 331 and the cover assembly 300 and the base assembly 200. Thus, after the telescopic tube 330 is blocked or damaged, the replacement of the telescopic tube 330 can be facilitated.

[0247] Without limitation, the joint 331 can be a plastic part.

[0248] On the premise of no conflict, different embodiments or different technical features in the present disclosure can be arbitrarily combined to form new embodiments.

[0249] It should be understood that the above embodiments are all exemplary and do not cover all possible implementation manners included in the claims. Without departing from the scope of the present disclosure, various deformations and changes can also be made on the basis of the above embodiments. Similarly, the various technical features of the above embodiments can also be arbitrarily combined to form additional embodiments of the present invention that may not be clearly described. Therefore, the above embodiments only represent several implementation manners of the present invention and do not limit the protection scope of the present invention patent.
