Description

Technical Field

[0001] This invention belongs to the field of charging technology, and specifically relates to a dust collection system. Background Technology

[0002] With the increasing frequency of use of electrical appliances, households typically use a variety of appliances, such as vacuum cleaners and electric irons. These appliances all need to be connected to a matching charging device for charging and storage. However, the charging and storage methods of these devices are usually limited to a single mode, either standing on the ground or hanging on the wall. This limits the application scenarios of the charging devices to a certain extent. For example, if the application location does not have the conditions for vertical storage of the charging device, then vertical charging appliances cannot be used. If the application location does not have the conditions for hanging storage of the charging device, then hanging charging appliances cannot be used. Summary of the Invention

The wall-mounted bracket 400 is provided with at least one through hole 402, through which a fixing member passes to the vertical wall to fix the wall-mounted bracket 400 to the vertical wall. The fixing member can be an expansion screw or a bolt, etc. In this embodiment, for example, the wall-mounted bracket 400 is provided with one through hole 402 near the top and one near the bottom, and the wall-mounted bracket 400 is fixedly suspended on the wall by bolts. In other embodiments, the through hole may also be provided at other locations on the wall mount 400, as long as it can be used to fix the wall mount 400 to a vertical wall, and the present invention does not limit this.

[0114] Please see Figures 19 to 21In some embodiments, the wall mount 400 may include a slide rail 403 and a locking structure. The locking structure includes at least a first locking position 404 and a second locking position 405. In some embodiments, there may be multiple slide rails 403, which are vertically fixed to the wall mount 400, allowing the object to be hung to slide on the slide rails 403 and thus be fixed to the wall mount 400. In this embodiment, the slide rail 403 includes a first slide rail and a second slide rail, which are symmetrically arranged on the wall mount 400. For example, the first slide rail and the second slide rail are symmetrically arranged on both sides of the wall mount 400 and are parallel to the plane on which the wall mount 400 is located.

[0115] Please see Figures 19 to 21 In some embodiments, the slide 403 can be a raised structure, while in other embodiments, the slide 403 can also be a groove structure or a magnetic structure. The slide 403 here only needs to enable the object to be suspended to slide on the slide 403, and the specific form of the slide 403 is not limited.

[0116] Please see Figures 19 to 21 In some embodiments, the wall mount 400 is further provided with a first locking position 404. In this embodiment, the first locking position 404 is disposed between the slide rails 403 on both sides of the wall mount 400, and is located on one side of the slide rails 403. In other embodiments, the first locking position 404 can also be disposed at other positions on the wall mount 400, such as in the middle of the two slide rails 403, as long as the first locking position 404 can fix the object to be hung. The specific placement of the first locking position 404 is not limited in this invention. The first locking position 404 is used to fix the vertical position of the object to be hung on the wall mount 400.

[0117] Please see Figures 19 to 21 In some embodiments, the first locking position 404 can be a movable locking position, specifically allowing the first locking position 404 to move away from the wall-mounting connection mechanism 401 under the action of an external force. In this embodiment, the side of the first locking position 404 near the slide rail 403 is connected to the wall-mount bracket 400, while the other side of the first locking position 404 is freely suspended. When an external force is applied to the side of the first locking position 404 away from the wall-mount bracket 400, the first locking position 404 on this side can move away from the wall-mounting connection mechanism 401. When the external force is removed, the side of the first locking position 404 away from the wall-mount bracket 400 returns to its original position, thereby realizing the connection and fixation of the object to be hung to the wall-mount bracket 400.

[0118] Please see Figures 19 to 21In some embodiments, the second locking position 405 may be located on the side of the wall mount 400 near the bottom. In some embodiments, the second locking position 405 may be a non-movable locking position. In other embodiments, the second locking position 405 may be a movable locking position.

The connecting plate is arranged vertically, and the multiple supporting plates are spaced apart and fixedly connected to the connecting plate and the wall mount 400, and are perpendicular to the connecting plate to provide a supporting effect on the object to be hung in the horizontal direction, preventing swaying due to the gap between the wall mount connecting mechanism 401 and the wall mount 400, and making the connection between the wall mount connecting mechanism 401 and the wall mount 400 more stable.

[0123] Please refer to the following: Figures 19 to 22The wall-mounted locking device of the present invention further includes a wall-mounted connecting mechanism 401, which is disposed on the object to be hung and is used in conjunction with the wall-mounted bracket 400. The wall-mounted connecting mechanism 401 may include a sliding track 139 and a locking structure, wherein the locking structure includes at least a first locking structure 140 and a second locking structure 142.

[0124] Please refer to the following: Figures 19 to 22 The number of matching slides 139 can be set according to the number of slides 403 on the wall mount 400. In this embodiment, since the slides 403 on the wall mount 400 include a first slide and a second slide, the matching slides 139 also include a first matching slide and a second matching slide. The first matching slide and the second matching slide are symmetrically arranged on both sides of the wall mount connection mechanism 401 and respectively match the first slide and the second slide, allowing the slide 403 to slide within the matching slide 139.

[0125] Please refer to the following: Figures 19 to 22 In some embodiments, the sliding track 139 can be a protruding structure, while in other embodiments, the sliding track 139 can also be a groove structure or a magnetic structure. The sliding track 139 here can be used to cooperate with the sliding track 403 so that the object to be suspended can slide on the sliding track 403. The specific form of the sliding track 139 is not limited.

[0126] Please refer to the following: Figures 19 to 22 Specifically, for example, slide 403 is a raised structure, and slide 139 is a recessed structure. More specifically, for example, a raised structure can be provided on each side of the wall mount 400, and correspondingly, two recessed structures are provided on the object to be hung. The size of the recessed structure matches the size of the raised structure, allowing the two raised structures on the wall mount 400 to slide in the recessed structure. In this embodiment, the raised structure is, for example, a strip-shaped structure protruding from the surface of the wall mount 400. In other embodiments, the raised structure can also be a protruding dot structure protruding from the surface of the wall mount 400, or a raised structure of other shapes. In this invention, the shape of the raised structure is not specifically limited, as long as it can achieve sliding by embedding the raised structure into the corresponding recessed structure. In some embodiments, the length of the raised structure can be the same as the side length of the wall mount 400. In other embodiments, the length of the raised structure can also be less than the side length of the wall mount 400.

[0127] Please refer to the following: Figures 19 to 22In some embodiments, when the wall mount 400 is provided with a first locking position 404, a corresponding first locking position engaging structure 140 is provided on the wall mount connecting mechanism 401. In this embodiment, the first locking position engaging structure 140 is disposed on one side of the engaging slide 139 and engages with the first locking position 404, allowing the first locking position 404 to be embedded in the first locking position engaging structure 140. In other embodiments, the specific position of the first locking position engaging structure 140 can be set according to the position of the first locking position 404, which is not limited in this invention.

[0128] Please refer to the following: Figure 2 , Figures 19 to 22 In some embodiments, a release button 408 is provided on the side of the first locking engagement structure 140 away from the wall mount 400. When the object to be hung is fixed on the wall mount 400, the release button 408 is pressed. Under the action of the release button 408, the first locking position 404 moves away from the wall mount connecting mechanism 401, thereby disengaging the first locking position 404 from the first locking engagement structure 140, thus completing the disassembly process between the wall mount 400 and the wall mount connecting mechanism 401. In addition, the object to be hung can be detached from the wall mount 400.

[0129] Please refer to the following: Figures 19 to 22 In some embodiments, when the wall mount 400 is provided with a second locking position 405, a corresponding second locking position engaging structure 142 is provided on the wall mount connecting mechanism 401. In this embodiment, the second locking position engaging structure 142 is located on the side of the wall mount connecting mechanism 401 near the bottom. In other embodiments, the position of the second locking position engaging structure 142 can be determined according to the position of the second locking position 405. The second locking position engaging structure 142 engages with the second locking position 405, allowing the second locking position 405 to be embedded in the second locking position engaging structure 142. Under the cooperative action of the second locking position 405 and the second locking position engaging structure 142, the wall mount 400 is prevented from sliding relative to the wall mount connecting mechanism 401, thereby fixing the object to be hung to the wall mount 400. In some embodiments, when the second locking position 405 is a movable locking position, a release button can also be provided on the side of the second locking position engaging structure 142 away from the wall mount 400 for pressing the second locking position 405.

The width between the two sides of the U-shape is, for example, 40mm-70mm, preferably 50mm-60mm, specifically, for example, 57.8mm. The width of the two sides of the third sliding rib 518 is greater than the width between the two first sliding ribs 505 and the width between the two second sliding ribs 506.

[0138] In addition, the distance between the first sliding rib 505 and the second sliding rib 506 is, for example, 1mm-5mm, preferably 2mm-4mm, specifically 2.9mm, and the distance between the second sliding rib 506 and the third sliding rib 518 is, for example, 2mm-8mm, preferably 3-7mm, specifically 4mm.

[0139] Please see Figure 27 In some embodiments, the locking groove 503 is disposed on the bottom plane of the charging device 1. The length of the locking groove 503 is, for example, 10mm-40mm, preferably 15mm-30mm, and specifically, for example, 29mm. The width of the locking groove 503 is, for example, 2mm-6mm, preferably 3mm-5mm, and specifically, for example, 4.6mm. The distance between the locking groove 503 and the outer shell of the charging device 1 is, for example, 8mm-15mm, preferably 10mm-13mm, and specifically, for example, 11.9mm.

[0140] Please refer to the following: Figure 27 and Figure 28 In some embodiments, the second locking unit 502 may have multiple sliding ribs, which are parallel to each other. The sliding ribs in the second locking unit 502 are staggered with the sliding ribs in the first locking unit 501. When the first locking unit 501 and the second locking unit 502 are closed, the sliding ribs and sliding ribs in the two locking units form an interlocking structure, making the connection between the first locking unit 501 and the second locking unit 502 more stable after they are closed.

[0141] Please refer to the following: Figure 27 and Figure 28 In this embodiment, based on the number of sliding ribs in the first locking unit 501, the second locking unit 502 is provided with, for example, two first-level sliding ribs 507 and two second-level sliding ribs 508. The first-level sliding ribs 507 and the second-level sliding ribs 508 are parallel to the sliding ribs, and the first-level sliding ribs 507 and the second-level sliding ribs 508 are parallel to each other.

[0142] Please refer to the following: Figure 27 and Figure 28 When the first locking unit 501 and the second locking unit 502 are closed, the first sliding rib 505 and the first mating sliding rib 507 interlock, and the second sliding rib 506 and the second mating sliding rib 508 interlock. When the charging device 1 is connected to the fixed base 520, the first sliding rib 505 and the first mating sliding rib 507, and the second sliding rib 506 and the second mating sliding rib 508 interlock and cooperate simultaneously, so that the charging device 1 and the fixed base 520 are stably connected, improving the strength of the structure. Moreover, the interlocking cooperation between the first sliding rib 505 and the first mating sliding rib 507, and the second sliding rib 506 and the second mating sliding rib 508 can ensure that the structure is not easy to shake.

[0143] Please refer to the following: Figure 27 and Figure 28 In some embodiments, the lengths of the multiple mating sliding ribs may be different. The length of the mating sliding rib can be determined based on the length of the mating sliding rib and the external dimensions of the second locking unit 502. It is only necessary to ensure that the sliding rib and the mating sliding rib are interlocked without gaps. In this embodiment, for example, when the first locking unit 501 and the second locking unit 502 are closed, the length of the first mating sliding rib 507 is greater than the length of the second mating sliding rib 508.

[0144] Please refer to the following: Figure 27 and Figure 28 In some embodiments, the second locking unit 502 is further provided with a third sliding rib 534 for interlocking with the third sliding rib 518 in the first locking unit 501, so as to further improve the structural strength and stability of the locking structure.

[0145] Please refer to the following: Figures 28 to 31In some embodiments, the second locking unit 502 may further include a locking base 509, a locking cover plate 513, and a latching structure 530. The locking base 509 is, for example, L-shaped. The portion of the L-shaped locking base 509 parallel to the plane of the fixed base 520 is defined as the horizontal portion 531, and the portion of the L-shaped locking base 509 perpendicular to the plane of the fixed base 520 is defined as the vertical portion 532. A latching button hole 533 is provided on the vertical portion 532. Multiple sliding ribs are symmetrically distributed on both sides of the latching button hole 533, and one end of the sliding rib is fixed to the side surface of the vertical portion 532 adjacent to the horizontal portion 531. The extending direction of the sliding rib is parallel to the horizontal portion 531. For example, two first sliding ribs 507 are located on both sides of the locking base 509, two second sliding ribs 508 are located on both sides of the locking base 509, and two third sliding ribs 534 are located on both sides of the locking base 509. In this embodiment, one end of the first sliding rib 507, the second sliding rib 508, and the third sliding rib 534 is fixed on the vertical part 532, and they are arranged sequentially along the side of the vertical part 532 away from the horizontal part 531 towards the horizontal part 531. The first sliding rib 507, the second sliding rib 508, and the third sliding rib 534 are parallel to each other and parallel to the horizontal part 531. In this embodiment, the length of the first sliding rib 507 is greater than the length of the second sliding rib 508 and less than the length of the third sliding rib 534.

[0146] Please refer to the following: Figures 28 to 31The distance between the two first sliding ribs 507 is, for example, 20mm-50mm, preferably 30mm-40mm, specifically 38.6mm. The distance between the two first sliding ribs 507 can be less than the distance between the two first sliding ribs 505. The distance between the two second sliding ribs 508 is, for example, 30mm-60mm, preferably 40mm-50mm, specifically 46.8mm. The distance between the two second sliding ribs 508 can be less than the distance between the two second sliding ribs 506. The distance between the first sliding rib 507 and the second sliding rib 508 is, for example, 1mm-5mm, preferably 2mm-4mm, specifically 2.8mm. The distance between the first sliding rib 507 and the second sliding rib 508 can be less than the distance between the first sliding rib 505 and the second sliding rib 506. The distance between the second sliding rib 508 and the third sliding rib 534 is 2mm-8mm, preferably 3-7mm, specifically 3mm. The distance between the second sliding rib 508 and the third sliding rib 534 can be less than the distance between the second sliding rib 506 and the third sliding rib 518.

[0147] Please see Figure 29 In some embodiments, a rib 535 may be provided on one side of the sliding rib adjacent to the latch button hole 533 along the extension direction of the sliding rib. The shape of the rib 535 is not specifically limited here. In some embodiments, ribs 535 may be provided on all sides of the sliding rib. In other embodiments, ribs 535 may be provided on only some sides of the sliding rib. In this embodiment, for example, a rib 535 is provided on one side of the latch button hole 533 along the extension direction of the first sliding rib 507 and the second sliding rib 508.

[0148] Please see Figures 28 to 30 The second locking unit 502 may further include a locking cover plate 513. The locking cover plate 513, together with the vertical portion 532 and the horizontal portion 531 of the locking base 509, forms a closed cavity. Specifically, the locking cover plate 513 has groove-shaped structures 536 on both sides that mate with the protruding ribs 535 on the sides of the sliding ribs. Horizontally moving the locking cover plate 513 causes the protruding ribs 535 to insert into the groove-shaped structures 536, thereby tightly engaging the locking cover plate 513 with the locking base 509. A locking hole 514 is provided on the side of the locking cover plate 513 away from the horizontal portion 531 of the locking base 509.

[0149] Please see Figure 28 , Figure 29 and Figure 31The locking structure 530 includes a button 512, a tongue-shaped protrusion 516, and a locking block 504. The button 512 is fitted into the locking button hole 533, allowing the button 512 to slide relative to the locking button hole 533. One end of the tongue-shaped protrusion 516 is connected to the side of the button 512 adjacent to the closed cavity, and the other end of the tongue-shaped protrusion 516 is located on the side of the locking hole 514 away from the vertical portion 532. The tongue-shaped protrusion 516 forms an inclined angle with the horizontal direction away from the vertical portion 532, and the inclined angle ranges from 0 to 90°. In this embodiment, the inclined angle is, for example, 45°. In this embodiment, the end face of the other end of the tongue-shaped protrusion 516 is parallel to the vertical portion 532. The locking block 504 is fitted onto the tongue-shaped protrusion 516 and is vertically positioned. One end of the locking block 504 is aligned with the locking hole 514, and this end can extend and retract within the locking hole 514. The end of the locking block 504 near the locking hole 514 is beveled to facilitate engagement with the latch groove 503 on the first locking unit 501. The button 512 slides relative to the latch button hole 533, causing the tongue-shaped protrusion 516 to move horizontally. Because the tongue-shaped protrusion 516 is inclined upwards, the distance between the locking block 504 and the tongue-shaped protrusion 516 and the horizontal portion 531 of the locking base 509 continuously changes. This causes the end of the locking block 504 near the locking hole 514 to extend and retract within the locking hole 514, meaning the end of the locking block 504 near the locking hole 514 is either lower or higher than the locking hole 514. When one end of the hole 514 is higher than the locking hole 514, the locking block 504 is at least partially exposed in the locking hole 514. The width of the locking block 504 is, for example, 16mm-25mm, preferably 18mm-23mm, specifically, for example, 21mm. The distance from the locking block 504 to the vertical part 532 is 8mm-15mm, preferably 10mm-13mm, specifically, for example, 11.6mm. The thickness of the locking block 504 is, for example, 2mm-6mm, preferably 3mm-5mm, specifically, for example, 4.4mm.

[0150] Please see Figure 28 , Figure 29 and Figure 31 Specifically, when button 512 moves the tongue-shaped protrusion 516 closer to the latch button hole 533, the engagement point between the locking block 504 and the tongue-shaped protrusion 516 moves away from the horizontal portion 531 of the locking base 509, and the locking block 504 moves towards the locking hole 514, thus exposing the locking block 504 in the locking hole 514. When button 512 moves the tongue-shaped protrusion 516 away from the latch button hole 533, the engagement point between the locking block 504 and the tongue-shaped protrusion 516 moves closer to the horizontal portion 531 of the locking base 509, and the locking block 504 moves away from the locking hole 514, so that the beveled end face of the locking block 504 is flush with the plane of the locking hole 514.

[0151] Please see Figure 28 , Figure 29 , Figures 31 to 33 In some embodiments, the second locking unit 502 further includes a spring element (not shown), which is disposed on the side of the tongue-shaped protrusion 516 near the horizontal portion 531 of the locking base 509. The spring element is connected between the button 512 and the locking cover plate 513, and the direction of the spring force of the spring element is parallel to the horizontal portion 531 of the locking base 509. The spring element is, for example, a spring. In this embodiment, the button 512 pulls or pushes the tongue-shaped protrusion 516 by the stretching or compression of the spring, thereby moving the tongue-shaped protrusion 516 closer to or further away from the latch button hole 533.

[0152] Please see Figures 26 to 33In use, with the locking structure 530 in its initial position, the second locking unit 502 moves horizontally along the first locking unit 501. During this movement, the multiple sliding ribs in the first locking unit 501 interlock with the multiple mating sliding ribs in the second locking unit 502. When the inclined end face of the locking block 504 contacts the bottom surface of the charging device 1, under the pressure of the bottom surface of the charging device 1, the locking block 504 gradually moves away from the bottom surface of the charging device 1. The locking block 504 and the tongue protrusion... The joint of part 516 moves closer to the horizontal part 531 of the locking base 509, thereby driving the tongue-shaped protrusion 516 to move away from the latch button hole 533. At this time, the elastic element gradually changes from the initial state to the compressed state until the locking block 504 is lowered to a position flush with the plane of the locking hole 514. The second locking unit 502 and the first locking unit 501 continue to move relative to each other in the horizontal direction. When the end of the locking block 504 near the locking hole 514 is aligned with the latch groove 503 on the bottom surface of the charging device 1, the bottom of the charging device 1... As the pressure on the locking block 504 disappears, the spring element gradually resets, returning from its compressed state to its initial state. The spring element pushes the button 512 towards the latch button hole 533. The movement of the button 512 causes the tongue-shaped protrusion 516 to move closer to the latch button hole 533. The junction between the locking block 504 and the tongue-shaped protrusion 516 gradually moves away from the horizontal part 531 of the locking base 509. Then, the locking block 504 moves towards the locking hole 514 until the spring element has fully reset, and the latch structure 530... Returning to the initial position, the locking block 504 exposes the locking hole 514 and is inserted into the locking groove 503, thus fixing the first locking unit 501 and the second locking unit 502. Due to the interlocking and cooperation of the multiple sliding ribs in the first locking unit 501 and the multiple cooperating sliding ribs in the second locking unit 502, the locking structure 522 has good structural strength and small gaps, which avoids shaking after the first locking unit 501 and the second locking unit 502 are fixedly locked, thus improving the stability and safety of the structure.

[0153] Please see Figures 26 to 33When it is necessary to disengage the first locking unit 501 and the second locking unit 502, the button 512 can be pressed. Pressing the button 512 will cause the tongue-shaped protrusion 516 to gradually move away from the locking button hole 533. The elastic element will gradually change from the initial state to the compressed state. The joint between the locking block 504 and the tongue-shaped protrusion 516 will gradually approach the horizontal part 531 of the locking base 509. The locking block 504 will gradually move away from the locking hole 514, so that the locking block 504 is lowered to a position flush with the plane where the locking hole 514 is located. At this time, the first locking unit 501 and the second locking unit 502 will be disengaged. The first locking unit 501 and the second locking unit 502 will be moved in opposite directions along the horizontal direction, so that the multiple sliding ribs in the first locking unit 501 will disengage from the multiple mating sliding ribs in the second locking unit 502, thereby realizing the disengagement of the first locking unit 501 and the second locking unit 502.

[0154] Please see Figures 2 to 7 As shown, the circuit board provided by this invention has a power rating of 5W to 400W. The circuit board also has multiple output voltages and multiple terminals, including a first terminal 203, a second terminal 204, a third terminal 205, and a fourth terminal 206, providing multiple charging methods for various electronic devices. The battery pack 3 can charge or discharge the circuit board through the third terminal 205.

[0155] This invention also provides various charging components; please refer to [link / reference]. Figure 2 and Figure 7 As shown, the charging assembly includes a charging device 1 and an electronic device. In one embodiment of the present invention, the electronic device is, for example, a typical mobile phone, tablet, or laptop. When charging, the smaller mobile phone can be placed in the receiving slot 134 (the tablet or laptop is placed on one side of the charging device 1), and the charging interface of the mobile phone or tablet is connected to the first terminal 203 using a data cable to charge the electronic device mobile phone or tablet.

[0156] Please see Figure 2 and Figure 36 As shown, the electronic device is, for example, a vacuum cleaner 6. On the side of the vacuum cleaner 6 near its battery pack 3, a fourth interface 66 is provided, which matches the fourth terminal 206. When the vacuum cleaner 6 is fixed on the charging device 1, the fourth interface 66 is electrically connected to the fourth terminal 206 to charge the vacuum cleaner 6.

[0157] Please see Figure 37 As shown, the vacuum cleaner 6 includes a housing 61, a dust collection unit 62 mounted on the housing 61, a suction generating unit 63, an air duct unit 64, and a floor brush 65.

[0158] Please see Figure 37 , Figure 38 and Figure 39 As shown, the housing 61 includes a body 611 disposed along a first direction AA, a handle 612 extending outward from one side of the body 611 along a second direction BB, and a base 613 located at the end of the handle 612 away from the body 611. The body 611 is provided with a receiving groove 6111 disposed along the first direction AA, an air inlet 6112, a locking assembly 6113, an elastic mechanism 6114, and a first limiting part 6115. The receiving groove 6111 has a generally arc-shaped cross-section and is used to accommodate the dust collection unit 62 and the suction generating unit 63. The air inlet 6112 includes a first air inlet 61121 and a first air outlet 61122. The first air inlet 61121 is disposed along the first direction AA. The first air outlet 61122 passes through the bottom wall of the receiving groove 6111 to cooperate with the dust collection unit 62 located within the receiving groove 6111, thereby guiding the airflow entering from the first air inlet 61121 into the dust collection unit 62 through the first suction inlet 6212. A locking assembly 6113 is disposed at the bottom of the receiving groove 6111 to cooperate with the dust collection unit 62, thereby fixing the dust collection unit 62 and the suction generating unit 63 within the receiving groove 6111. The locking assembly 6113 includes a second latch (not shown), a second elastic element (not shown) cooperating with the second latch, and an unlocking button 61133 mounted on the second latch. By pressing the unlocking button, the suction generating unit 63 can be lifted upwards by means of the elastic mechanism 6114. Please refer to... Figure 2 As shown, the pop-up mechanism 6114 is fixedly installed on the bottom wall of the receiving groove 6111 to cooperate with the suction generating unit 63. The pop-up mechanism 6114 includes a push pin 61141 and a first elastic element (not shown) that cooperates with the push pin 61141. In this embodiment, the pop-up mechanism 6114 is positioned facing the suction generating unit 63, but it is understood that in other embodiments, the pop-up mechanism 6114 can also be positioned facing the dust collection unit 62, thereby cooperating with the dust collection unit 62. The first limiting part 6115 is located in the receiving groove 6111 and faces the suction generating unit 63. When the unlock button 61133 is pressed to release the dust collection unit 62, the elastic mechanism 6114 can push the suction generating unit 63 upward, and the suction generating unit 63 rotates around... Figure 5 The first pivot 601 rotates, thereby causing the suction generating unit 63 to drive the dust collection unit 62 to disengage from the receiving groove 6111.

[0159] Please see Figures 37 to 39As shown, the handle 612 is formed by extending outward from the bottom of the self-accommodating groove 6111 along the second direction BB. The handle 612 includes a grip portion 6123 and a support portion 6124 arranged parallel to each other. The grip portion 6123 and the support portion 6124 are located between the body 611 and the base 613. The grip portion 6123, the support portion 6124, the body 611, and the base 613 together form a parallelogram. A switch button 6121 and a boss 6122 are provided on the side of the grip portion 6123 near the support portion 6124. The switch button 6121 is located close to the body 611, and the boss 6122 is located on the side of the switch button 6121 away from the body 611. The handle 612 and the body 611 have an angle α, which is between 80 degrees and 140 degrees. Preferably, the angle α is between 90 degrees and 120 degrees, and more preferably, it is between 105 degrees and 115 degrees, such as 107 degrees, 110 degrees, or 113 degrees. The handle 612 has a height H in the direction perpendicular to the first direction AA, which is between 85 mm and 110 mm. The handle 612 also has a switch button 6121 and a boss 6122. The switch button 6121 is used to control the operation of the vacuum cleaner 1. The boss 6122 is located on the side of the switch button 6121 away from the body 611, so that when the user holds the handle 612, the boss 6122 can apply a lifting force, and also protect the switch button 6121. Preferably, the boss 6122 is arc-shaped.

[0160] Please see Figures 37 to 39 As shown, the handle 612 includes a grip portion 6123 and a support portion 6124 arranged parallel to each other. The grip portion 6123 and the support portion 6124 are located between the body 611 and the base 613. The output shaft of the suction generating unit 63 defines a first reference line L1 parallel to the first direction AA. The side of the grip portion 6123 away from the support portion 6124 defines a second reference line L2 parallel to the second direction BB. The perpendicular line from the bottom end of the side of the grip portion 6123 away from the support portion 6124 to the first reference line L1 defines a fourth reference line L4. The line connecting the bottom end of the side of the grip portion 6123 away from the support portion 6124 to the center of gravity CG of the motor of the suction generating unit 63 defines a fourth reference line L3. The angle between the second reference line L2 and the first reference line L1 is equal to the aforementioned angle α. The motor's center of gravity CG is located on the first reference line L1. The motor's center of gravity CG is located between the intersection of the first reference line L1 and the second reference line L2 and the fourth reference line L4 and the second reference line L2. That is, the angle β between the fourth reference line L3 and the first reference line L1 is between 60 degrees and 90 degrees, preferably between 80 degrees and 90 degrees, such as 82 degrees, 84 degrees, 86 degrees, 88 degrees, etc. This design allows the motor's center of gravity of the suction generating unit 63 to be closer to the web of the hand, which is ergonomic and provides a better user experience.

[0161] Please see Figures 37 to 40 As shown, the dust collection unit 62 is mounted on the suction generating unit 63 to cooperate with the air inlet duct 6112 to collect dust, dirt, etc. The dust collection unit 62 includes a dust cup 621, a filter assembly (not shown), a cup lid 623, and a fourth elastic element 624. In this embodiment, the dust cup 621 is cylindrical, and a first suction inlet is formed on its side wall. The first suction inlet can be, for example, rectangular, and corresponds to the position of the first air outlet 61122 of the air inlet duct 6112. The airflow entering from the first air inlet 61121 is guided into the dust collection unit 62 through the first suction inlet. The axis of the dust cup 621 is parallel to the first direction AA. The dust cup 621 has a first latch 6211 on the side facing the receiving groove 6111, which engages with the second latch of the latching assembly 6113. The engagement of the first latch 6211 and the second latch secures the dust collection unit 62 within the receiving groove 6111. In this embodiment, the first latch 6211 is located on the dust collection unit 62, and the latching assembly 6113 is positioned directly opposite the dust collection unit 62. However, it is understood that in other embodiments, the first latch 6211 may also be located on the suction generating unit 63, in which case the latching assembly 6113 is positioned directly opposite the suction generating unit 63. The cup lid 623 is pivotally mounted on the dust cup 621. One end of the fourth elastic element 624 abuts against the dust cup 621, and the other end abuts against the cup lid 623. When the dust collection unit 62 disengages from the receiving groove 6111, the cup lid 623 automatically opens under the action of the fourth elastic element 624, allowing the user to empty the dust from the dust cup 621. When the dust collection unit 62 is housed in the receiving groove 6111, the receiving groove 6111 abuts against the side wall of the cup lid 623, causing the cup lid 623 to close. At this time, the fourth elastic element 624 undergoes elastic deformation. In this embodiment, the fourth elastic element 624 is a torsion spring. Please refer to... Figure 3 As shown, preferably, the body 611 is also provided with a holding mechanism 6116 that cooperates with the cup lid 623. When the dust collection unit 62 is received in the receiving groove 6111, the holding mechanism 6116 holds the cup lid 623, so that the cup lid 623 is in a closed state, at which time the fourth elastic element 624 undergoes elastic deformation.

[0162] Please see Figures 37 to 40As shown, the suction generating unit 63 is pivotally mounted on the body 611 via a first pivot member 601, allowing the suction generating unit 63 to rotate around the first pivot member 601. In this embodiment, the first pivot member 601 is a pivot, but it is understood that in other embodiments, the first pivot member 601 may also be a shaft hole. The suction generating unit 63 includes a second limiting portion 6313, which cooperates with the first limiting portion 6115 to limit the rotation range of the suction generating unit 63. When the first limiting portion 6115 abuts against the second limiting portion 6313, the suction generating unit 63 will be unable to rotate around the first pivot member 601 in a direction away from the body 611. In this embodiment, the second limiting portion 6313 is disposed on the suction generating unit 63, at which time the first limiting portion 6115 is directly opposite the suction generating unit 63. However, it is understood that in other embodiments, the second limiting part 6313 may also be disposed on the dust collection unit 62, in which case the first limiting part 6115 is directly opposite the dust collection unit 62.

[0163] Please see Figure 37 and Figure 38 As shown, the duct unit 64 is used in conjunction with the air inlet duct 6112 and the floor brush 65 to perform the function of the vacuum cleaner 1. The duct unit 64 includes an air duct 641, which can be a rigid plastic tube, a steel tube, or a flexible tube.

[0164] Please see Figure 37 , Figure 38 , Figure 41 and Figure 42 The floor brush 65 includes a floor brush housing 651, a roller brush 655, an air duct connection 652, and a walking component 654. The rear end of the floor brush housing 651 is connected to the air duct connection 652. The floor brush housing 651 has a receiving cavity located at the front end of the floor brush housing 651. The rear end of the receiving cavity is connected to the second dust inlet 653. The roller brush 655 is rotatably installed in the receiving cavity. The walking component 654 may be, for example, a driving wheel, which is installed at the bottom of the rear end of the floor brush housing 651.

[0165] Specifically, please refer to Figure 37 , Figures 41 to 44The floor brush housing 651 includes a floor brush base plate 6513, a rear top cover 6511, a front top cover 6512, and side sealing plates 6514 located on both sides of the floor brush housing 651. The front top cover 6512 covers the front end of the floor brush base plate 6513, and the rear top cover 6511 covers the rear end of the floor brush housing 651. The front top cover 6512, the floor brush base plate 6513, and the side sealing plates 6514 on both sides together form a receiving cavity. The floor brush base plate 6513 has a base plate opening 5 in the area at the bottom of the receiving cavity for the roller brush 655 to be exposed. The second dust inlet 653 includes a connecting section 6533, an enlarged section 6532, and a first interface 6531 arranged sequentially. The second dust inlet 653 is connected to the middle of the rear wall of the receiving cavity through the connecting section 6533. The duct connecting part 652 is used to connect with one end of the duct 641. A second interface 6521 is provided at the end of the duct connecting part 652 near the floor brush housing 651. The first interface 6531 and the second interface 6521 can be connected, for example, through a flexible hose.

[0166] Please see Figure 37 , Figure 41 and Figure 44 In this embodiment, to ensure the suction efficiency of the vacuum cleaner body 6, the opening areas of the first suction inlet 6212 and the second suction inlet 653 of the dust cup 621, and the cross-sectional area of ​​the inner hole of the duct 641, need to satisfy the following: the opening area of ​​the first suction inlet is smaller than the cross-sectional area of ​​the inner hole of the duct, the opening area of ​​the second suction inlet 653 is smaller than the cross-sectional area of ​​the inner hole of the duct, and the opening area of ​​the first suction inlet 6212 is larger than the opening area of ​​the second suction inlet 653. As an example, the ratio of the opening area of ​​the second suction inlet 653 to the cross-sectional area of ​​the inner hole of the duct is between 0.5 and 0.6, preferably between 0.53 and 0.56, for example, 0.55. As an example, the ratio of the opening area of ​​the first suction inlet to the cross-sectional area of ​​the inner hole of the duct is between 0.65 and 0.8, preferably between 0.70 and 0.76, for example, 0.72.

[0167] Please see Figures 37 to 46 When the vacuum cleaner is working, the airflow is sucked into the vacuum cleaner through the floor brush 65 and the air duct 641 in sequence. The airflow enters the air intake duct 6112 through the first air inlet 61121, and enters the dust cup 621 through the first dust inlet 6212 through the first air outlet 61122. The airflow is filtered by the filter assembly in the dust cup 621, and finally discharged through the exhaust port of the suction generating unit 63.

[0168] Please see Figure 38 and Figure 40When the user needs to clean the dust in the dust collection unit 62, first press the unlock button 61133. The locking assembly 6113 disengages from the first locking buckle 6211. At this time, the suction generating unit 63 rotates upward around the first pivot member 601 under the action of the pop-up mechanism 6114, causing the cup lid 623 to disengage from the holding mechanism 6116. The cup lid 623 automatically opens under the action of the fourth elastic element 624, making it convenient for the user to empty the dust in the dust cup 621. When the first limiting part 6115 abuts against the second limiting part 6313, the suction generating unit 63 will no longer be able to rotate upward around the first pivot member 601. When the user has finished cleaning the dust in the dust cup 621, he / she simply presses the suction unit into the receiving groove 6111. At this time, the first latch 6211 and the latch assembly 6113 cooperate to fix the dust collection unit 62 and the suction generating unit 63 in the receiving groove 6111. The holding mechanism 6116 holds the cup cover 623, so that the cup cover 623 is in the closed state.
