Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0013] Example 1: As shown in the attached figure, a dust collection device for a sweeper includes a vehicle body 1, a working area 2 is provided on the rear side of the vehicle body 1, a dust collection bin 22 is provided on the upper part of the working area 2, a lifting plate 5 is provided at the bottom of the dust collection bin 22, and a vertical lifting device is provided in the working area 2 in conjunction with the lifting plate 5, which drives the lifting plate 5 to move upward; the bottom surface of the dust collection bin 22 faces the working area 2, and a flexible sealing gasket 23 is provided on the bottom surface of the dust collection bin 22.

[0014] Further detailed structure, such as Figure 1 As shown, a drive chamber 3 is provided on the side of the working area 2. A vertical electric actuator 6 is provided inside the drive chamber 3 as a vertical lifting device. A guide groove 33 is provided on the side wall of the drive chamber 3. The vertical electric actuator 6 drives the lifting module 4 to move through the guide groove 33. In order to improve the stability of the lifting module 4 when moving vertically, at least two fixed seats 31 are provided on the outer wall of the drive chamber 3. The guide rod 32 is supported by the two fixed seats 31. A guide block 41 is provided on the lifting module 4. The guide block 41 cooperates with the guide rod 32 to guide the vertical movement.

[0015] like Figure 3 As shown, the lifting module 4 is provided with a drive seat 41, and the drive seat 41 is provided with a rotating shaft assembly connected to the lifting plate 5. The rotating shaft assembly includes a bearing sleeve 43 and a rotating shaft 44. The rotating shaft 44 is connected to the bottom surface of the lifting plate 5 and causes the lifting plate 5 to swing synchronously.

[0016] Two oscillating magnetic suction components are provided on the drive base 41 in conjunction with the lifting plate 5. They are fixed to the drive base 41 by magnetic fixing bases 47. Furthermore, the oscillating magnetic suction components are respectively arranged on the front and rear sides of the rotating shaft assembly, namely the rear magnetic suction component 45 and the front magnetic suction component 46. Both the rear magnetic suction component 45 and the front magnetic suction component 46 are controllable magnetic suction components. Their function is to enable the lifting plate 5 to swing on the rotating shaft 44, so as to facilitate the movement of the garbage can onto the lifting plate 5 and to provide a placement angle for the garbage can 7 when it is flipped, so that it can be stably squeezed under the dust collection bin 22.

[0017] Furthermore, this utility model designs the lifting plate 5 as a quadrilateral with three open sides, and a support block 51 is provided on the rear side of the lifting plate 5. When the support block 51 is installed, its rear side is higher than its front side.

[0018] like Figure 4 As shown, a positioning rod 21 is provided inside the work area 2, which is used to position the trash can 7 when it is placed.

[0019] Example 2: Based on the specific structural details disclosed in Embodiment 1, this utility model, when used, such as Figure 5 , 6 As shown in Figure 7, it can accommodate or combine trash cans 7 of different heights and widths. In the prior art, the trash can 7 is equipped with a moving wheel 71 on one side of its bottom, so that the user can push the trash can 7 to move.

[0020] When using this invention, the operator controls the rear magnetic component 45 to be energized, such as... Figure 5 As shown, the entire lifting plate 5 is tilted at the rear end and touches the ground at the rear end, allowing the trash can 7 to be pushed onto the lifting plate 5 as a whole.

[0021] After the trash can 7 is fully inserted onto the lifting plate 5, the operator energizes the front magnetic suction component 46 and de-energizes the rear magnetic suction component 45. At this time, the lifting plate 5 is in the following state: Figure 6 As shown; inside the drive chamber 3, a vertical electric push rod 6 is installed to drive the lifting module 4 to move vertically through the guide groove 33. The lifting module 4 drives the drive seat 41, bearing sleeve 43, rotating shaft 44, and lifting plate 5 to move upward synchronously until the top surface of the trash can 7 is squeezed onto the flexible sealing gasket 23. The flexible sealing gasket 23 is usually made of sponge or rubber, which can achieve a better sealing effect under vertical compression.

[0022] Furthermore, this utility model also provides a support block 51 on the rear side of the lifting plate 5. When the support block 51 is installed, its rear side is higher than its front side. Since the bottom of the trash can 7 is provided with a movable wheel 71, the support block 51 can support the movable wheel 71 on the opposite side. Since the rear side of the support block 51 is higher than its front side, when it is vertically supported, it can give the trash can 7 an upward local thrust, preventing the trash can 7 from slipping outward when it is subjected to vertical force.

[0023] With the above structural design, when the lifting plate 5 moves upward, it presses the top surface of the trash can 7 against the flexible sealing gasket 23 to achieve a seal, thus preventing dust leakage when receiving trash or dust. The working area 2 designed in this invention has a volume larger than that of the trash can 7. This design can compensate for any errors in the specifications of trash cans 7 currently on the market by lifting them.

[0024] This invention solves the problem that existing sweepers cannot be used with ordinary trash cans. By adopting this technical solution, there is no need to equip a special trash receiving device, and it can be used with ordinary trash cans to achieve unified trash collection.
