The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

[0028] Please also refer to Figure 1-8 The present embodiment provides a dual-dust suction mode sweeping toy car, including a car body 1 formed with a dust suction chamber, wherein a fan generates negative pressure suction inside the dust suction chamber for sucking in garbage and dust to achieve dust removal and cleaning effects.

[0029] In this embodiment, the vehicle body 1 has the appearance of a large truck and comprises a chassis 10, a driver's cabin 20, a power supply box 30, and a dust collection chamber 40, which are sequentially mounted on the chassis 10. At least two pairs of wheels 11 are rotatably connected to the chassis 10, allowing the vehicle body 1 to move on a flat surface. A connecting shaft 12 is provided at the rear end of the chassis 10 for pivotally connecting the dust collection chamber 40, thereby rotatably connecting the two. An elastic clip 13 is also provided on the outer wall of the chassis 10, located on the inner side of the chassis 10 where it meets the dust collection chamber 40, for snapping the chassis 40 together and releasably securing the two.

[0030] In other embodiments, the vehicle body 1 may have the appearance of other vehicle models. Depending on the vehicle model, the cockpit 20, the power box 30, and / or the dust chamber 40 may be omitted. In this case, the position of the dust chamber within the toy vehicle may be adjusted based on the vehicle model. The chassis 10 may also be provided without the connecting shaft 12 and the elastic buckle 13. In this case, the dust chamber 40 is fixed to the chassis 10.

[0031] The dust collection chamber 40 includes a fixed inner shell 41 and an outer shell 42. The inner shell 41 is recessed to form a dust collection chamber 410. The inner shell 41 is fixedly connected to the outside of the dust collection chamber 410 with a fan 60, and the inner shell 41 is provided with an air inlet 411 and an air outlet 412 corresponding to the fan 60. It can be understood that the fan 60 includes a first motor 61 and fan blades 62 that are driven and connected. The first motor 61 is fixed to the inner shell 41 via a mounting base, and the fan blades 62 are rotatably arranged between the air inlet 411 and the air outlet 412. When the first motor 61 is started, the fan blades 62 rotate at high speed to draw air out of the dust collection chamber 410, thereby generating negative pressure suction inside the dust collection chamber 410.

[0032] A first dust suction port 4101 is provided between the dust suction chamber 410 and the chassis 10. When the first dust suction port 4101 is in communication with the interior of the dust suction chamber 410, the fan 60 is activated to suck in trash and dust through the first dust suction port 4101. Because the first dust suction port 4101 is located on the chassis 10, the toy car can suck trash in its path into the dust suction chamber 410 through the first dust suction port 4101.

[0033] The dust collection chamber 410 also includes a second dust collection port 4102 extending through the dust collection chamber 40. A dust collection tube 51 is connected to the second dust collection port 4102. The dust collection tube 51 is made of a flexible material (e.g., flexible plastic, resin, etc.). One end of the dust collection tube 51 is fixed to the second dust collection port 4102, while the other end is removably connected to the dust collection chamber 40. Specifically, this embodiment utilizes a through-hole 421 provided on the outer shell 42 for plugging and unplugging the dust collection tube 51, enabling pluggable connection of the dust collection tube 51. As will be appreciated, since the dust collection tube 51 is removably connected to the dust collection chamber 40, the toy car can control the swing direction and position of the dust collection tube 51 to draw trash outside its travel path into the dust collection chamber 410. In other embodiments, a ring or other structure may be provided on the outer wall of the outer shell 42 to allow for removable connection of the dust collection tube 51 to the vehicle body 1.

[0034] To achieve the desired switching between the two vacuuming modes, a switch 52 is slidably connected within the vacuum chamber 410 between the first vacuum port 4101 and the second vacuum port 4102. The switch 51 includes a baffle 521 and a shift block 522. The baffle 521 can be connected to cover either the first vacuum port 4101 or the second vacuum port 4102. The shift block 522 is movably exposed on the vacuum chamber 40. When the shift block 522 moves, it drives the baffle 521 to reciprocate between a first position covering the first vacuum port 4101 and a second position covering the second vacuum port 4102.

[0035] Thus, when the shift block 522 moves and drives the baffle 521 to the first position, the dust collection chamber 410 is connected to the outside world through the second dust collection port 4102 and the dust collection tube 51. In this mode, dust collection can be performed by swinging the position and direction of the dust collection tube 51. When the shift block 522 moves and drives the baffle 521 to the second position, the dust collection chamber 410 is connected to the outside world through the first dust collection port 4101. In this mode, dust collection can be performed by moving the chassis 10.

[0036] It will be appreciated that in this embodiment, the second dust suction port 4102 and the first dust suction port 4101 are located on different planes. In this case, the second dust suction port 4102 and the first dust suction port 4101 are arranged alternately and staggered (i.e., the second dust suction port 4102 and the first dust suction port 4101 are not located on the same cross-section). The baffle 521 can be moved to selectively block one of the dust suction ports. In this embodiment, since the second dust suction port 4102 is located on a sidewall perpendicular to the first dust suction port 4101, the baffle 521 is a rectangular plate fixed vertically by two plates. In other embodiments, if the second dust suction port 4102 and the first dust suction port 4101 are located on the same plane, for example, if both the second dust suction port 4102 and the first dust suction port 4101 extend between the dust suction chamber 410 and the chassis 10, the baffle 521 can be a flat plate, and the baffle 521 can be moved to selectively block one of the dust suction ports.

[0037] To ensure stable sliding movement between the inner wall of the dust collection chamber 410 and the switch 52, the dust collection chamber 410 is further provided with at least one positioning post 4103. Correspondingly, a connecting arm 523 extends outward from the baffle 521 in correspondence with the positioning post 4103. The connecting arm 523 defines a sliding hole 5231. The sliding hole 5231 extends in the same direction as the movement of the baffle 521, and the sliding hole 5231 is sleeved over the corresponding positioning post 4103 and moves in conjunction with it.

[0038] To achieve the desired sliding movement between the positioning post 4103 and the sliding hole 5231, and to prevent the switch 52 from moving randomly and affecting the stable operation of different vacuuming modes, a positioning rib 4104 is provided on the outer side of at least one positioning post 4103 in the vacuum chamber 410. The sliding hole 5231, which mates with the positioning post 4103, has two positioning grooves 5232 spaced apart on the inner side opposite the positioning rib 4104. Each positioning groove 5232 can detachably mate with the positioning rib 4104. When the two mate, the baffle 521 is positioned in either the first or second position.

[0039] In this embodiment, the outer shell 42 is provided with a chamber cover 422 corresponding to the dust collection chamber 410. The chamber cover 422 is detachably connected to the outer shell 42 via a knob switch 4221. The outer shell 42 is provided with a flip cover 423 corresponding to the air outlet 412. The flip cover 423 is pivotally connected to the outer shell 42. It will be understood that the provision of the chamber cover 422 facilitates the opening and closing of the dust collection chamber 410, allowing for quick removal of large pieces of debris within the dust collection chamber 410. The provision of the flip cover 423 also facilitates the opening and closing of the outer shell 42, allowing the dust collection chamber 410 to quickly remove fine dust through the gaps between the air inlet 411, the air outlet 412, and the flip cover 423. In other embodiments, the outer shell 42 may not be provided with the flip cover 423.

[0040] It can be understood that in order to further quickly clean dust, the dust collection box 40 is rotatably mounted on the chassis 10 in this embodiment. Specifically, one end of the inner shell 41 is pivotally connected to the connecting shaft 12, and the other end of the outer shell 42 is provided with a snap block 424 corresponding to the elastic snap 13. The snap block 424 can be snapped and connected to the elastic snap 13. When the two are snapped together, the dust collection box 40 can be fixed to the chassis 10. When the two are snapped together, the dust collection box 40 can be rotated relative to the chassis 10.

[0041] To improve the rotational stability of the dust collection chamber 40 and limit its rotational angle, in this embodiment, the inner and outer housings 41, 42 are connected to the chassis 10 via a piston structure. This piston structure includes a cylinder 71 secured to the chassis 10 and a piston rod 72 secured between the inner and outer housings 41, 42. The piston rod 72 is capable of reciprocating within the cylinder 71 under load. In other embodiments, the piston structure may not be provided between the dust collection chamber 40 and the chassis 10.

[0042] Therefore, when cleaning large pieces of trash from the dust collection chamber 410, the knob switch 4221 is turned to separate the chamber cover 422 and the outer shell 42, opening the dust collection chamber 410 for quick dumping. When cleaning fine dust from the dust collection chamber 410, the flip cover 423 is turned to open the outer shell 42, then the snap-on block 424 and the elastic snap 13 are snapped off and the dust collection chamber 40 is rotated. The piston rod 72 moves within the cylinder 71 as the dust collection chamber 40 rotates, until the end of the piston rod 72 abuts against the inner wall of the cylinder 71. At this point, the dust collection chamber 40 has rotated to its maximum angle relative to the chassis 10, allowing the fine dust from the dust collection chamber 410 to slide out of the outer shell 42 under the action of gravity and external forces.

[0043] To achieve better dust collection, in this embodiment, a drive assembly 80 is also installed within the chassis 10. The drive assembly 80 includes a second motor 81, a first gear chain 82 drivingly connected to the second motor 81, a second gear chain 83 drivingly connected to the first gear chain 82, and a third gear chain 84 drivingly connected to the first gear chain 82. In other embodiments, the chassis 10 may not be equipped with the drive assembly 80.

[0044] The final gears of the first and second toothed chains 82, 83 are each secured with a cleaning wheel 91. The cleaning wheel 91 is positioned adjacent to the first suction port 4101 and is configured to rotate under the control of the first and second toothed chains 82, 83, thereby sweeping garbage and dust from the vicinity of the first suction port 4101 into the first suction port 4101. The final gear of the third toothed chain 84 is secured to the rotating shaft of a pair of drive wheels 92. The drive wheels 92 are exposed on the same side of the chassis 10 as the wheels 11 and are configured to rotate under the control of the third toothed chain 84, thereby enabling the chassis 10 to move automatically. It will be appreciated that an isolation cover 93 is removably attached to the exterior of the drive wheels 92, which can be enclosed by the isolation cover 93. When the isolation cover 93 is in place, the drive wheels 92 cannot touch the ground. While the cleaning wheel 91 can continue to rotate, the chassis 10 cannot move automatically.

[0045] In this embodiment, the drive assembly 80 also includes a power switch 85 electrically connected to the first motor 61 and the second motor 81. The power switch 85 is fixed on the chassis and exposed to the vehicle body 1. The power switch 85 can control the start and stop of the first motor 61 and the second motor 81, and thus the start and stop of the fan 60, the cleaning wheel 91 and the driving wheel 92 can be controlled at the same time.

[0046] Please refer to Figure 9 In the second embodiment, the drive assembly 80 further includes a control switch 86. The control switch 86 is fixed to the outer wall of the dust collection compartment 40 adjacent to the switching switch 52. The control switch 86 is used to control the on / off current of the branch circuit where the second motor 81 is located, thereby controlling the operating state of the second motor 81. It will be understood that in the second embodiment, the switching switch 52 is provided with a toggle arm 524 extending from the control switch 86, and the toggle arm 524 is tactilely connected to the control switch 86.

[0047] In this embodiment, when the shift block 522 moves and the baffle 521 moves to the first position, the shift arm 524 moves and separates from the control switch 86. At this time, the control switch 86 is not activated by force, and the control switch 86 controls the second motor 81 to stop working. However, because the power switch 85 is still in the activated state, the fan 60 can continue to operate. When the shift block 522 moves and the baffle 521 moves to the second position, the shift arm 524 moves and contacts the control switch 86, pushing the control switch 86 to activate. At this time, the control switch 86 controls the second motor 81 to start working, driving the cleaning wheel 91 and the drive wheel 92 to start working simultaneously with the fan 60. It can be understood that the control switch 86 can change the operating state of the second motor 81 in response to the different movement positions of the toggle switch 52, which can save current loss, make the use of the toy car more convenient and reasonable, and greatly improve the user experience of the toy car.

[0048] For clarity, certain features of the present invention described in the context of separate embodiments may be combined in a single embodiment. Furthermore, various features of the present invention described in the context of a single embodiment may also be used individually or in any suitable subcombination.
