Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0026] 1 , a vacuum cleaner includes a body assembly 10 and a dust collecting assembly 20 connected to the body assembly 10. In this embodiment, the dust collecting assembly 20 is connected to the body assembly 10 so as to move along with the body assembly 10.

[0027] 2 , specifically, the dust collecting assembly 20 includes a dust cup 21 forming an accommodating space. In this embodiment, the dust cup 21 is detachably connected to the body assembly 10, thereby facilitating the replacement and cleaning of the dust cup 21.

[0028] Referring to Figure 3 , the dust collection assembly 20 further includes a separation barrel 22 and a filter 23, which are disposed together within the accommodating space. In this embodiment, the accommodating space is formed within the dust cup 21, thereby protecting the separation barrel 22 and filter 23 from the external environment of the dust cup 21. After air laden with dust and dirt is drawn into the dust cup 21, it is filtered by the separation barrel 22 and filter 23, and the filtered air is discharged from the dust cup 21.

[0029] 4 , the vacuum cleaner further comprises a docking structure for limiting the engagement of the body assembly 10 with the dust cup 21. In this embodiment, the dust cup 21 is detachably connected to the body assembly 10 using the docking structure.

[0030] Specifically, the docking structure includes a first limit block 31 that cooperates with the dust cup 21 and a first limit groove 32 that is provided on the body assembly 10 and matches the first limit block 31. In this embodiment, the first limit block 31 and the dust cup 21 are movably matched to achieve relative movement between the first limit block 31 and the dust cup 21. When the first limit block 31 and the dust cup 21 generate relative movement, the first limit block 31 and the first limit groove 32 also generate relative movement accordingly, thereby achieving locking and unlocking between the first limit block 31 and the first limit groove 32, and then achieving installation and removal between the dust cup 21 and the body assembly 10.

[0031] Specifically, by setting a rebound member between the first limit block 31 and the dust cup 21, when pressing force is applied to the first limit block 31 to deform the rebound member, the first limit block 31 and the dust cup 21 can be driven to move toward each other. After the pressing force applied to the first limit block 31 is removed, the rebound member drives the limit block 31 and the dust cup 21 to move away from each other.

[0032] When the first limiting block 31 and the dust cup 21 move toward each other, the first limiting block 31 and the first limiting groove 32 move away from each other, causing the first limiting block 31 to disengage from the first limiting groove 32, thereby unlocking the dust cup 21 from the body assembly 10. Conversely, when the first limiting block 31 and the dust cup 21 move away from each other, the first limiting block 31 and the first limiting groove 32 move toward each other, causing the first limiting block 31 to extend into the first limiting groove 32, thereby locking the dust cup 21 to the body assembly 10.

[0033] Furthermore, the dust cup 21 has a gripping groove 21a and an unlocking groove 21b that are spaced apart. In this embodiment, the gripping groove 21a and the unlocking groove 21b are respectively opened in different directions. The distance between the gripping groove 21a and the unlocking groove 21b is preferably adapted to the size of the user's palm. Therefore, after the user inserts different fingers of a single hand into the gripping groove 21a and the unlocking groove 21b, for example, inserting the index finger or ring finger into the gripping groove 21a and the thumb into the unlocking groove 21b, a gripping posture of the dust cup 21 can be formed, and the dust cup 21 can be grasped with one hand, which facilitates the grasping operation of the dust cup 21.

[0034] Furthermore, the first limit block 31 protrudes into the unlocking slot 21b in a direction away from the gripping slot 21a. After receiving an external force, the first limit block 31 moves toward the gripping slot 21a and separates from the first limit slot 32. In this embodiment, the direction of the unlocking slot 21b is the same as the protruding direction of the first limit block 31, and is also toward the direction of the first limit slot 32. When a finger is inserted into the unlocking slot 21b, a pressing force can be applied to the first limit block 31, thereby driving the first limit block 31 and the first limit slot 32 to generate a back-to-back movement, so that the first limit block 31 is disengaged from the first limit slot 32, thereby unlocking the dust cup 21 and the body assembly 10. Therefore, the user can disengage the first limit block 31 from the first limit slot 32 by grasping the gripping slot 21a and the unlocking slot 21b with one hand, thereby facilitating the disassembly and installation of the dust cup 21.

[0035] When disassembling the dust cup 21, insert your fingers into the grip groove 21a and the unlocking groove 21b at the same time. After forming a gripping posture, bring your fingers together toward the palm of your hand, and use the fingers in the unlocking groove 21b to press the first limit block 31 to unlock the dust cup 21 and the body assembly 10. Then, by gripping the grip groove 21a and the unlocking groove 21b, remove the dust cup 21 from the body assembly 10, thereby realizing one-handed disassembly and grabbing of the dust cup 21, and simplifying the disassembly process of the dust cup 21.

[0036] 5 , specifically, the dust cup 21 includes a cup body 21c and a cup cover 21d pivotally connected to the cup body 21c. In this embodiment, the cup cover 21d is connected to the cup body 21c via a pivot shaft, so that the cup cover 21d rotates relative to the cup body 21c to open and close.

[0037] Specifically, the accommodation space includes a filter cavity 21e formed within the cup lid 21d and a mounting cavity 21f formed within the cup body 21c and communicating with the filter cavity 21e. In this embodiment, the cup lid 21d has a dish-shaped structure, thereby forming the filter cavity 21e therein. The cup body 21c has a dish-shaped structure, thereby forming the mounting cavity 21f therein. When the cup lid 21d is closed over the cup body 21c, the filter cavity 21e and the mounting cavity 21f communicate with each other and together form the accommodation space.

[0038] Furthermore, the filter 23 is elastically supported against the inner wall of the filter cavity 21e. In this embodiment, the filter 23 is elastically supported against the inner wall of the cup cover 21d, so that it moves together with the cup cover 21d, that is, it rotates open and closed relative to the cup body 21c with the cup cover 21d. The filter 23 is preferably configured as an elastic filter sponge, which is pressed and deformed and then extended into the filter cavity 21e, so that the filter 23 can be installed on the cup cover 21d, which is convenient for installation and disassembly. Among them, the inner wall of the filter cavity 21e is not limited to the inner wall of the cup cover 21d. For example, when the inner wall of the cup cover 21d is formed with reinforcement ribs and other protrusions, the inner wall of the filter cavity 21e can be the outer wall of the aforementioned reinforcement ribs and other protrusions.

[0039] Furthermore, the separation barrel 22 is located in the mounting cavity 21f and abuts against the cup body 21c and the cup cover 21d. In this embodiment, when the cup cover 21d is covered on the cup body 21c, the separation barrel 22 abuts against the cup body 21c and the cup cover 21d, thereby preventing relative movement between the separation barrel 22 and the dust cup 21.

[0040] Moreover, when the cup cover 21d is rotated open relative to the cup body 21c, the separation barrel 22 is disengaged from the cup cover 21d. At this time, the separation barrel 22 can be removed from the cup body 21c, and the filter 23 can be removed from the cup cover 21d, thereby realizing the separate disassembly of the separation barrel 22 and the filter 23, making it convenient to remove the separation barrel 22 and the filter 23 from the dust cup 21 for cleaning or replacement.

[0041] Specifically, the dust cup 21 also includes a separation cup 21g connected to the cup body 21c and located in the installation cavity 21f, and an air outlet 21h provided on the cup cover 21d and connected to the filter cavity 21e. The separation barrel 22 has a separation portion 221 located in the separation cup 21g and a separation outlet 222 formed on the separation portion 221. In this embodiment, the separation portion 221 is a cylindrical structure, and a plurality of through holes are provided on the side wall of the separation portion 221. After the air containing dust enters the separation cup 21g, a cyclone is formed in the separation cup 21g, thereby separating the dust and the air. After separation by the separation cup 21g, the dust remains in the separation cup 21g and can flow from the separation cup 21g to the cup body 21c. The separated air flows from the multiple through holes on the separation portion 221 to the separation outlet 222, and after flowing through the filter 23, flows out of the dust cup 21 from the air outlet 21h.

[0042] Furthermore, the air outlet 21h and the separation outlet 222 are arranged on both sides of the filter 23, and the axis of the air outlet 21h and the axis of the separation outlet 222 are parallel to or collinear with each other. In this embodiment, the air outlet 21h, the filter 23 and the separation outlet 222 are arranged along the axial direction of the separation portion 221, that is, arranged along the vertical direction. The separated gas flows out of the separation portion 221 from the separation outlet 222, flows through the filter 23 and flows to the air outlet 21h, and flows out of the dust cup 21 from the air outlet 21h. During the whole process, the gas does not turn, thereby reducing the loss of airflow energy and improving the suction force of the vacuum cleaner.

[0043] Furthermore, the dust cup 21 also has a locking structure 21i that enables the cup body 21c to be snap-fitted with the cup cover 21d. In this embodiment, as shown in Figure 5, the locking structure 21i includes a locking tongue connected to the cup cover 21d and a lock buckle provided on the cup body 21c. The locking tongue is pivotally connected to the cup cover 21d through a movable shaft. A spring is provided between the locking tongue and the movable shaft. When the cup cover 21d is covered on the cup body 21c, the locking tongue is subjected to the deformation force of the spring and is buckled on the lock buckle, thereby achieving the locking of the cup cover 21d and the cup body 21c. Of course, the locking structure 21i can also adopt other existing specific structures.

[0044] Specifically, the gripping groove 21a, the locking structure 21i and the unlocking groove 21b are arranged along the vertical direction. In this embodiment, in conjunction with the azimuth coordinates in Figure 1, the vertical direction corresponds to the up and down direction in the coordinates. The dust cup 21 is roughly cylindrical, and the unlocking groove 21b and the gripping groove 21a are arranged on the upper and lower sides of the locking structure 21i relative to each other. The gripping groove 21a, the locking structure 21i and the unlocking groove 21b are all located on the same radial side of the dust cup 21, that is, the rear side of the dust cup 21, and are arranged adjacent to each other. Therefore, after the user grasps the gripping groove 21a and the unlocking groove 21b to remove the dust cup 21, he can extend the finger in the unlocking groove 21b to press the locking structure 21i, thereby opening the dust cup 21 with one hand, making it easier to clean the separation barrel 22 and the filter 23 in the dust cup 21.

[0045] Moreover, the gripping groove 21a, the locking structure 21i and the unlocking groove 21b are arranged close together, which makes the appearance of the dust cup 21 more concise and enhances the aesthetics.

[0046] Specifically, the gripping groove 21a and the unlocking groove 21b are both open and arranged in a direction away from the locking structure 21i. In this embodiment, as shown in Figure 3, the gripping groove 21a and the unlocking groove 21b are recessed in the outer end surface of the dust cup 21, so that the appearance of the dust cup 21 is not obtrusive. The dust cup 21 also has a first insertion space 21j opposite to the notch of the gripping groove 21a and a second insertion space 21k opposite to the unlocking groove 21b. The user inserts the finger into the gripping groove 21a through the first insertion space 21j and inserts the finger into the unlocking groove 21b through the second insertion space 21k, providing more operating space for the user to grasp the dust cup 21, making it easier for the user to insert the finger into the gripping groove 21a and the unlocking groove 21b for grasping.

[0047] Specifically, the docking structure also includes a second limiting block 33 connected to the dust cup 21 and a second limiting groove 34 provided on the body assembly 10 and matching the second limiting block 33. In this embodiment, the second limiting block 33 is fixedly connected to the dust cup 21. When the dust cup 21 is installed with the body assembly 10, the second limiting block 33 is inserted into the second limiting groove 34, thereby achieving the positioning and matching of the dust cup 21 with the body assembly 10. The docking structure utilizes the mutual cooperation between the first limiting block 31 and the first limiting groove 32, and the mutual cooperation between the second limiting block 33 and the second limiting groove 34, to avoid horizontal or vertical displacement or deflection between the dust cup 21 and the body assembly 10.

[0048] Furthermore, the first limit block 31 and the second limit block 33 protrude vertically from the end surface of the dust cup 21. In this embodiment, as shown in FIG2 , the first limit block 31 protrudes from the upper end surface of the dust cup 21, and the second limit block 33 protrudes from the lower end surface of the dust cup 21, so that the docking structure can more stably position the body assembly 10 and the dust cup 21, thereby improving the connection strength between the dust cup 21 and the body assembly 10.

[0049] Furthermore, the first limit block 31 and the second limit block 33 are located on the same radial side of the dust cup 21. In this embodiment, the first limit block 31 and the second limit block 33 are arranged in a vertical direction. The first limit block 31 and the second limit block 33 are both located on the rear side of the dust cup 21 and close to the user side, so that the user can easily operate the second limit block 33 to position and cooperate with the second limit groove 34 when grasping the dust cup 21, and to easily operate the first limit block 31 to lock and cooperate with the first limit groove 32.

[0050] Specifically, the vacuum cleaner further includes a fan assembly 40 connected to the body assembly 10. In this embodiment, the fan assembly 40 includes a motor and a fan that rotate coaxially.

[0051] Specifically, the body assembly 10 includes a fan compartment 11 that accommodates the fan assembly 40, and an air inlet 12 that connects the fan compartment 11 to the air outlet 21h. In this embodiment, when the motor drives the fan to rotate, negative pressure is formed in the fan compartment 11, driving external air from the air inlet 12 into the fan compartment 11, that is, driving the air in the dust cup 21 into the fan compartment 11.

[0052] Furthermore, the rotation axis of the fan assembly 40, the axis of the air inlet 12, and the axis of the air outlet 21h are parallel or collinear with each other. In this embodiment, the separated gas flows out of the dust cup 21 through the air outlet 21h, flows into the fan compartment 11 through the air inlet 12, and then flows out of the fan compartment 11 after being driven by the fan. During the entire process, the gas does not turn, thereby reducing the loss of airflow energy and improving the suction force of the vacuum cleaner. The gas can turn after flowing out of the fan compartment 11.

[0053] 3 and 5 , the separation barrel 22 further includes a mounting portion 223 connected to the separation portion 221, and a first sealing member 224 and a second sealing member 225 connected to the mounting portion 223. In this embodiment, the first sealing member 224 and the second sealing member 225 are both located on the mounting portion 223 by being embedded.

[0054] Specifically, the first seal 224 and the second seal 225 are arranged on opposite sides of the mounting portion 223 along the axis of the separation portion 221. The first seal 224 is arranged circumferentially around the axis of the separation portion 221 and abuts the cup cover 21d, and the second seal 225 is arranged circumferentially around the axis of the separation portion 221 and abuts the separation cup 21c. In this embodiment, the first seal 224 and the second seal 225 both adopt an annular closed structure. When the lower edge of the cup cover 21d abuts the first seal 224 and the upper edge of the separation cup 21c abuts the second seal 225, the dust cup 21 can be sealed, preventing dust or gas from overflowing from the dust cup 21 from the joint between the cup body 21c and the cup cover 21d.

[0055] Furthermore, the vacuum cleaner also includes a battery assembly 50 and a floor brush assembly 60 connected to the body assembly 10. In this embodiment, the battery assembly 50 provides a removable power source for the vacuum cleaner, freeing the vacuum cleaner from the constraints of a power cord, thereby being referred to as a cordless vacuum cleaner. The battery assembly 50 is detachably connected to the body assembly 10, making the battery assembly 50 replaceable. The floor brush assembly 60 is capable of moving along the surface to be cleaned and is rotatably connected to the body assembly 10. It can also remain upright on the ground while the vacuum cleaner is vacuuming the floor, thereby being referred to as an upright vacuum cleaner.

[0056] Furthermore, the battery assembly 50, the fan assembly 40, and the dust cup 21 are arranged along the axis of the separation portion 221. In this embodiment, as shown in FIG4 , the battery assembly 50, the fan assembly 40, and the dust cup 21 are arranged along the axis parallel to or substantially parallel to the separation portion 221, thereby saving radial space occupied by the vacuum cleaner, that is, saving horizontal space occupied by the vacuum cleaner, making the radial dimensions of the vacuum cleaner uniform and coordinated, and avoiding interference with the vacuuming operation of the vacuum cleaner.

[0057] Specifically, the floor brush assembly 60 is located on the side of the dust cup 21 away from the fan assembly 40. In this embodiment, the battery assembly 50, the fan assembly 40, the dust cup 21 and the floor brush assembly 60 are arranged in sequence along the axial direction of the separation portion 221.

[0058] 1 , the axis of the separator 221 corresponds to the up-down direction in the coordinates. Therefore, the battery assembly 50, fan assembly 40, and dust cup 21 are arranged from top to bottom, and the fan assembly 40, filter 23, and separator 221 are arranged from top to bottom. Furthermore, the battery assembly 50 is located at the top of the body assembly 10, which further facilitates heat dissipation from the battery assembly 50.

[0059] 6 , the body assembly 10 further includes a first frame 13 connected to the floor brush assembly 60 and a second frame 14 connected to the dust collection assembly 20. In this embodiment, the body assembly 10 is composed of the first frame 13 and the second frame 14 connected to each other. The floor brush assembly 60 and the dust collection assembly 20 are respectively connected to different frames of the body assembly 10, making the entire vacuum cleaner modular, which not only facilitates the assembly of the vacuum cleaner, but also facilitates the subsequent maintenance and replacement of the vacuum cleaner.

[0060] 7 , the dust cup 21 further comprises a first docking surface 211 forming an air outlet 21h and an air inlet 21m communicating with the interior of the separation cup 21g. In this embodiment, the first docking surface 211 is the top end surface of the dust cup 21, and the dust-laden gas enters the dust cup 21 through the air inlet 21m.

[0061] Specifically, the air inlet 21m is preferably provided on the cup body 21c, and the air outlet 21h is provided on the cup cover 21d, thereby increasing the distance between the air inlet 21m and the air outlet 21h and increasing the separation time of the separation cup 21g.

[0062] Of course, in some other embodiments, the air inlet 21m can also be set on the cup cover 21d, or on the cup cover 21d and the cup body 21c.

[0063] Continuing with reference to Figures 4 and 7, the second frame 14 further has a mounting groove 141 that matches the dust cup 21 and an air guide port 142 that is exposed toward the mounting groove 141 and connected to the air inlet 21m. In this embodiment, the outer wall of the dust cup 21 abuts against the inner wall of the mounting groove 141, thereby facilitating the positioning and docking of the dust cup 21 with the second frame 14 and improving the matching strength between the dust cup 21 and the second frame 14. A sealing member is provided between the air inlet 21m and the air guide port 142 to ensure the sealing after the air inlet 21m and the air guide port 142 are docked.

[0064] Furthermore, the mounting groove 141 has a second docking surface 1411 that is opposite to the first docking surface 211 and forms the air inlet 12. The first docking surface 211 and the second docking surface 1411 are parallel to each other and intersect in the horizontal plane, that is, the first docking surface 211 and the second docking surface 1411 are parallel to each other and are arranged at a certain angle relative to the horizontal plane. In this embodiment, the second docking surface 1411 is located at the top of the mounting groove 141. The first docking surface 211 and the second docking surface 1411 are both tilted along the front-to-back direction, that is, arranged in a manner of low front and high back, and are parallel to each other, so as to facilitate the positioning and docking of the dust cup 21 with the second frame 14, and then facilitate the accurate docking of the air inlet 21m with the air guide port 142, as well as the accurate docking of the air outlet 21h with the air inlet 12.

[0065] In addition, the first docking surface 211 is tilted relative to the horizontal plane, that is, the top end surface of the dust cup 21 is tilted, which can also save the space occupied by the dust cup 41 and save the materials required for molding the dust cup 41.

[0066] Furthermore, to enhance the fit between the dust cup 21 and the second frame 14, a limiting groove is formed on the first mating surface 211, and a limiting bump is formed on the second mating surface 1411. The cooperating limiting groove and limiting bump serve as positioning guides during assembly of the dust cup 21 and the second frame 14, and also limit left and right deviation after assembly.

[0067] Specifically, the vacuum cleaner further includes a dust suction pipe 70 connecting the floor brush assembly 60 and the air guide port 142. In this embodiment, dusty air enters the dust suction pipe 70 through the floor brush assembly 60 and is transported by the dust suction pipe 70 to the separation cup 21g for separation.

[0068] Furthermore, the battery assembly 50 and the fan assembly 40 are connected to the second frame 14, and the first frame 13 and the second frame 14 are detachably connected. In this embodiment, the frame assembly 10 is composed of the detachable first frame 13 and the second frame 14, which facilitates assembly and disassembly of the first frame 13 and the second frame 14, and also meets different usage requirements of the vacuum cleaner, such as using the components on the second frame 14 separately. The vacuum cleaner also includes a handle assembly 80 connected to the first frame 13, which is convenient for the user to hold and move the vacuum cleaner. The floor brush assembly 60 and the handle assembly 80 are connected to the first frame 13 to form a whole unit, and the dust collection assembly 20, the fan assembly 40, and the battery assembly 50 are connected to the second frame 14 to form a whole unit. The two units are fixed together by the detachable connection between the first frame 13 and the second frame 14, thereby forming the entire vacuum cleaner. This makes the entire vacuum cleaner modular, facilitating assembly and later maintenance and replacement of the vacuum cleaner.

[0069] In addition, considering that the dust collection assembly 20, the fan assembly 40, and the battery assembly 50 are all vulnerable parts or components that frequently require cleaning and maintenance, after connecting them to the second frame 14, it is only necessary to disassemble the second frame 14 to repair and maintain these parts, thereby reducing the repair and maintenance costs of the vacuum cleaner. At the same time, the dust collection assembly 20, the fan assembly 40, and the battery assembly 50 can meet the vacuuming needs of the vacuum cleaner. After installing them on the second frame 14, they can also be used as an independent vacuum cleaner. It is only necessary to remove the handle assembly 80 from the first frame 13 and use it as a vacuum tube, or dock it with other vacuum accessories. The operation of this independent vacuum cleaner is more convenient. Moreover, in addition to powering the fan assembly 40, the battery assembly 50 also powers the floor brush assembly 60.

[0070] Furthermore, the body assembly 10 further includes a storage cavity 15 formed between the first frame 13 and the second frame 14. In this embodiment, the storage cavity 15 can be formed solely on the first frame 13 or solely on the second frame 14, or a portion of the storage cavity 15 can be formed on the first frame 13 and the other portion can be formed on the second frame 14.

[0071] Specifically, the dust suction tube 70 is accommodated in the storage chamber 15. In this embodiment, it is preferred that the dust suction tube 70 is completely accommodated in the storage chamber 15, so as to better protect the dust suction tube 70 and prevent the user from being interfered with by the exposed dust suction tube and affecting the dust suction operation.

[0072] Of course, in some embodiments, the dust suction tube 70 may be partially accommodated in the storage cavity 15 and partially exposed outside the storage cavity 15 .

[0073] Moreover, arranging the dust suction tube 70 in the storage chamber 15 can also reduce the size of the entire vacuum cleaner, making the entire vacuum cleaner neater and more beautiful.
