Detailed Implementation

[0042] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0043] As a specific embodiment, the cleaning device of this utility model includes a main unit 1, a drive component 2, and a handle component 3.

[0044] The main unit 1 includes a housing 11 and a filter device 12. The housing 11 is provided with an air inlet 111 and an air outlet 112. Typically, the filter device 12 is a filter with at least one layer, which is surrounded by a filter device cover 121 that is detachably connected to the housing 11. The filter device cover 121 is provided with a dust suction inlet 122. The filter can be installed on the filter device cover 121 by means of snap-fit, screw connection, etc., and then the filter device cover 121 (containing the filter device 12 assembly) can be installed on the housing 11, thus realizing the assembly and disassembly of the cleaning device. Turning on the drive device 21 (described later) allows air to pass through the dust suction inlet 122 and the filter device cover 121 before entering the air inlet 111.

[0045] The drive assembly 2 includes a drive device 21, which is fixed inside the housing 11 and located between the air inlet 111 and the air outlet 112. The rotation axis of the drive device 21 is parallel to the direction from the air inlet 111 to the air outlet 112. Typically, the rotation axis of the drive device 21 is collinear with the axis of the air inlet 111 and the axis of the air outlet 112.

[0046] The handle assembly 3 includes an operation assembly 31, which includes a rotating part 312 and a gripping part 311 fixedly connected to the rotating part 312. It can be understood that "fixedly connected" means that the rotating part 312 and the gripping part 311 are connected in the use state. However, in terms of structure, the rotating part and the gripping part can be integrally formed or can be formed by splicing together multiple detachable parts.

[0047] The rotating member 32 is rotatably connected to the main unit 1, allowing the gripping part 311 to rotate relative to the main unit 1. The plane formed by the rotation of the gripping part 311 is parallel to the rotation axis of the drive device 21. It is easy to understand that there is a gap between the gripping part 311 and the main unit 1, resulting in a gap between the plane formed by the rotation of the gripping part 311 and the rotation axis of the drive device 21. Furthermore, the axis of rotation of the gripping part 311 relative to the main unit 1 is perpendicular to the plane formed by the rotation of the gripping part 311.

[0048] The working principle is as follows: When in use, turn on the drive device 21 and bring the filter device 12, the suction inlet 122 (described later), or the suction extension 4 (described later) close to the object to be cleaned; air and dust are drawn towards the filter device 12 due to the negative pressure of the air inlet 111, and the air passes through the filter device 12, the air inlet 111, and the drive device 21 in sequence before being discharged from the air outlet 112; dust and other objects cannot pass through the filter device 12 and are retained on the outside of the filter device 12, thereby achieving both suction and filtration.

[0049] During the use of the cleaning device by activating the drive unit 21, the plane formed by the rotation of the grip 311 is parallel to the rotation axis of the drive unit 21, so that the inertial force generated by the rotation of the drive assembly 2 is perpendicular to the plane formed by the rotation of the grip 311, rather than parallel to it. Therefore, the inertial force generated by the rotation of the drive assembly 2 will not cause the main unit 1 to rotate relative to the handle assembly 3, thereby ensuring that the rotation angle of the handle assembly 3 relative to the main unit 1 is stable and easy to use. In some other embodiments, the grip 311 is located on one side of the housing 11 and extends along the length of the housing 11. That is, the axis of the grip 311 can be parallel to the housing 11 or inclined relative to the housing 11. In this way, whether the user needs to use the vacuuming function (i.e., the air inlet is facing the object to be cleaned) or the blowing function (i.e., the air outlet is facing the object to be cleaned), it can be easily controlled by the rotatable handle assembly.

[0050] It is understandable that the drive device 21 can be a single motor as shown in the attached figure, which enables airflow to flow from the negative pressure inlet at one end of the motor to the negative pressure outlet at the other end, or it can be two motors, one of which blows air and the other of which draws air.

[0051] As one specific implementation, the main unit 1 also includes a handle connector 13, and the handle assembly 3 also includes a rotating member 32; the outer shell 11 is provided with a handle connector groove 113, and the handle connector 13 is detachably fixedly connected to the outer shell 11 (e.g., by snap-fit ​​connection, fastener connection, etc.) and covers the handle connector groove 113; the grip (311) and the rotating member 32 are respectively located on both sides of the handle connector 13 along the width direction of the outer shell (11), the side wall of the rotating part 312 fits against the handle connector 13 and the bottom end of the rotating part 312 is fixedly connected to the bottom end of the rotating member 32, so that the rotating member 32 is rotatably connected to the main unit 1. When the handle assembly 3 is rotatably connected to the handle connector 13 and the bottom end of the rotating part 312 is fixedly connected to the rotating member 32, there is a large operating space, which is not limited by the space of the inner cavity of the outer shell 11, so that the handle assembly 3 can be easily rotatably connected to the main unit 1. It is easy to understand that in other specific implementations, the handle connector 13 can also be part of the outer shell 11, that is, the handle connector 13 and the outer shell 11 are integrated.

[0052] As one specific implementation, the handle assembly 3 also includes a steering operation member 33 with a shift protrusion 331. The rotating member 32 is provided with multiple (the "multiple" means at least two) shift slots 321. For example, there are two shift slots 321 evenly distributed around the rotation axis of the rotating member 32, so that the handle assembly 3 has two positions with a phase difference of 180 degrees relative to the main unit 1 (that is, the user can adjust the handle position by rotating it 180° clockwise or counterclockwise). Of course, three or more shift slots 321 can also be provided as needed. The steering operation member 33 is movably connected to the handle connector 13, and the steering operation member 33 tends to insert into the shift slot 321. For example, the handle assembly 3 also includes a shift elastic member 332 and a steering operation member mounting bracket 333 fixedly connected to the handle connector 13. The two ends of the shift elastic member 332 abut against the steering operation member 33 and the steering operation member mounting bracket 333 respectively, so that the steering operation member 33 tends to insert into the shift slot 321. It is easy to understand that the gear shift protrusion 331 and gear shift groove 321 can also be reversed, that is, the gear shift protrusion 331 is set on the rotating member 32, and the gear shift groove 321 is set on the steering operation member 33. For example, the steering operation member 33 can be a button, that is, the steering operation member 33 can move longitudinally along the housing 11 in a direction that is approximately perpendicular to the rotation axis of the drive device 21. This embodiment can further ensure the stability of the rotation angle of the handle assembly 3 relative to the main unit 1, and can also realize multi-position use. As another embodiment, the steering operation member 33 can also be a sliding key, that is, it can move axially along the housing 11 in a direction that is approximately parallel to the rotation axis of the drive device 21. When the steering operation member 33 is also a sliding key, the steering operation member mounting bracket 333 corresponding to the steering operation member 33 can be a separate structure, or it can be part of the housing 11 or the handle connector 13.

[0053] As one specific embodiment, the handle assembly 3 also includes a damping device 314 that is sleeved on the bottom end of the rotating part 312 and has elasticity. The handle connector 13 is provided with a rotation positioning sidewall 132. The damping device 314 abuts against the rotation positioning sidewall 132. The damping device 314 can be a rubber ring or silicone to have elasticity. It provides elastic force so that when the rotating part 312 and the rotation positioning sidewall 132 rotate, they will rub against the rotating part 312 or the rotation positioning sidewall 132 to generate a damping torque, thereby hindering the rotation of the rotating part 312, thereby achieving the purpose of slowing down the rotation speed. It can also further ensure the stability of the rotation angle of the handle assembly 3 relative to the main unit 1 and prevent the handle assembly 3 from shaking relative to the main unit.

[0054] As one specific implementation, the cleaning device of this utility model embodiment further includes an electronic control board 8 disposed within the housing 11, and an operating component 31 provided with a handle input device 38 electrically connected to the electronic control board 8, and / or a handle output device 39 electrically connected to the electronic control board 8; the handle input device 38 is a device for inputting electrical signals to the electronic control board 8, which may be a button, a touch screen, etc.; the handle output device 39 is a device for outputting electrical signals to the electronic control board 8, which may be an LED light, a display screen, etc. It is easy to understand that the electrical connection between the handle input device 38 and the electronic control board 8, and the electrical connection between the handle output device 39 and the electronic control board 8, necessarily involves wires connecting the two. The rotating part 312 is provided with a rotating part wiring port 313, and the rotating component 32 is provided with a rotating component wiring hole 323; and one of the rotating part 312 and the rotating component 32 is provided with a rotation limiting groove 341, and the other is provided with a rotation limiting protrusion 34 that can abut against the inner wall of the rotation limiting groove 341. The rotation limit protrusion 34 abuts against the inner wall of the rotation limit groove 341, which can ensure that the rotation angle of the operating component 31 relative to the host 1 is within 360 degrees, that is, the operating component 31 will not rotate more than 360 times relative to the host 1, thereby preventing the wire from being damaged due to multiple rotations and improving reliability.

[0055] As one specific implementation, the bottom wall of the handle connector groove 113 is provided with an inward wiring hole 114; the electronic control board 8 and the handle connector 13 are respectively located on both sides of the bottom wall of the handle connector groove 113. A portion of the wires leading from the operating component 31 to the rotating component wiring hole 323 and a portion of the wires leading from the electronic control board 8 to the handle connector groove 113 can be connected by quick connectors, thereby facilitating the rotational connection of the handle assembly 3 and the main unit 1. In other embodiments, the handle connector groove 113 is a through hole opened in the housing 11. In this case, a portion of the wires leading from the operating component 31 to the rotating component wiring hole 323 can be directly connected to the main control board.

[0056] As one specific implementation, the housing 11 includes a detachable front cover 115, and typically, the air inlet 111 is located on the front cover 115. The drive assembly 2 also includes a drive unit frame 211 and flexible damping pads 212. The damping pads 212 are disposed between the drive unit 21 and the front cover 115, and / or, the damping pads 212 are disposed between the drive unit 21 and the drive unit frame 211. For example, damping pads 212 are provided at both ends of the drive unit 21. The drive unit frame 211 is detachably fixedly connected to the front cover 115, so that the damping pads 212 tend to be compressed. For example, the drive unit frame 211 is provided with mounting ears 213, and screws (not shown in the figure) pass through the mounting ears 213 and are threadedly connected to the front cover 115, so that the damping pads 212 tend to be compressed. This embodiment can reduce the vibration generated by the rotation of the drive device 21. After the drive device 21 is fixed to the front cover 115 of the housing through the drive device frame 211, the front cover 115 of the housing is then connected to other parts of the housing 11, such as by screw connection or threaded connection, so that the drive component 2 is located inside the housing 11, which facilitates the assembly of the drive component 2.

[0057] As one specific implementation, the drive assembly 2 also includes a battery rack 222, on which a power supply 22 for the battery 221 is provided; the control board 8 is mounted on the battery rack 222 or the drive unit frame 211, and the battery rack 222 is connected to the drive unit frame 211 such that the battery rack 222 is located between the drive unit 21 and the air outlet 112. It should be noted that the battery rack 222 and the drive unit frame 211 can be fixedly connected or detachably connected. The air input from the air inlet 111 passes through the drive unit 21 and then flows to the surroundings of the drive unit 21 (such as...). Figure 11 The air flows in the vertical direction (as shown), passes through the battery 221 and / or the electronic control board 8, and is discharged from the air outlet 112. The battery 221, battery holder 222, and electronic control board 8 are integrated with the drive device 21. Referring to the aforementioned embodiment that facilitates the assembly of the drive assembly 2, this embodiment facilitates the assembly of the drive assembly 2, battery 221, battery holder 222, and electronic control board 8. Furthermore, the air passing through the battery 221, battery holder 222, and electronic control board 8 can improve heat dissipation for the battery 221, battery holder 222, and electronic control board 8, thereby also improving reliability.

[0058] As one of the specific implementation methods, such as Figure 12As shown, the cleaning device of this embodiment further includes a vacuuming extension 4; the vacuuming extension 4 includes a vacuuming contact portion 41 and a vacuuming connecting portion 42; the vacuuming contact portion 41 is used to approach or contact the object to be vacuumed, and the vacuuming connecting portion 42 is used to connect to the vacuuming inlet 122 to extend the vacuuming inlet 122. A brush holder 43 is rotatably connected to the vacuuming contact portion 41, and brush bristles 431 are provided on the brush holder 43; the brush holder 43 can be rotated to a folded state where the brush bristles 431 overlap with the vacuuming contact portion 41, and to an unfolded state where the brush bristles 431 are completely offset from the vacuuming contact portion 41. When a larger negative pressure is required, the brush holder 43 can be rotated to the folded state to use the vacuuming extension 4; when it is necessary to clean the object to be vacuumed with a brush, the brush holder 43 can be rotated to the unfolded state, and the object to be vacuumed can be cleaned with a brush using the brush bristles 431, thereby allowing the vacuuming extension 4 to be changed as needed for convenient use. In a more specific embodiment, the brush holder 43 includes a brush holder side wall 432 and a brush holder end wall 433, making the brush holder 43 U-shaped when viewed from the front. One of the side wall of the dust suction contact part 41 and the side wall 432 of the brush holder is provided with a rotatable connecting protrusion 414, and the other is provided with a rotatable connecting groove 434. The rotatable connecting protrusion 414 fits into the rotatable connecting groove 434, so that the brush holder 43 is rotatably connected to the dust suction contact part 41. Here, "the rotatable connecting protrusion 414 fits into the rotatable connecting groove 434" means that when viewed from the side, the outer circle of the rotatable connecting protrusion 414 coincides with the inner wall of the rotatable connecting groove 434. For example, when viewed from the side, the rotatable connecting protrusion 414 is cross-shaped, and the four ends of the cross shape are all located on the same outer circle; or, for example, when viewed from the side, the rotatable connecting protrusion 414 is circular, and the circle itself is its circumcircle. One of the sidewalls of the suction contact portion 41 and the sidewall 432 of the brush holder is provided with a bristle positioning protrusion 415, and the other is provided with at least two bristle positioning grooves 435. The bristle positioning protrusion 415 is inserted into the bristle positioning groove 435. For example, there are two bristle positioning grooves 435, which are evenly distributed around the axis connecting the brush holder 43 and the suction contact portion 41, so that the brush holder 43 can rotate relative to the suction contact portion 41 to an unfolded state and a folded state. It is easy to understand that the sidewall 432 of the brush holder or the bristle positioning protrusion 415 is elastic, so that the brush holder 43 can rotate relative to the suction contact portion 41 when the bristle positioning protrusion 415 is outside the bristle positioning groove 435. Usually, the sidewall 432 of the brush holder is provided with a weight-reducing groove 439, etc., to reduce the weight of the brush holder 43.
