[0004] However, technicians found that the aforementioned sweepers were ineffective at cleaning carpets. Utility Model Content

[0005] The purpose of this application is to disclose a dust removal device, a sweeper, and a vacuum cleaner. The dust removal device, sweeper, and vacuum cleaner can effectively clean dust from carpets and other objects requiring dust removal.

[0010] In some embodiments, the dust removal device includes a limiting mechanism that limits the beating element to allow the beating element to move linearly.

[0011] In some embodiments, the dust removal device includes a housing, and the limiting mechanism is a limiting hole disposed in the housing; each of the tapping members extends out of the corresponding limiting hole so as to abut against the corresponding cam mechanism.

[0028] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0029] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0030] See Figure 1 , Figure 2 and Figure 3 This application discloses a dust removal device. The dust removal device includes a drive mechanism (shown schematically in the figure), a beating mechanism 1, and a suction mechanism. The drive mechanism can be a motor, etc., capable of driving the beating mechanism. Of course, one embodiment where the drive mechanism drives the drive shaft to rotate is that the drive mechanism can cause the drive shaft to rotate in different directions, for example, first clockwise and then counterclockwise; or, another embodiment, as described later in this application, is that it rotates only in one direction.

[0031] See Figure 5 , Figure 6 and Figure 3 and combined Figure 2 and Figure 4The tapping mechanism 1 includes a drive shaft 11, a cam mechanism 12, a tapping element 13, and a reset mechanism 14. The drive mechanism drives the drive shaft 11, which in turn drives the cam mechanism 12 to abut against the tapping element 13, pushing the tapping element 13 so that it moves towards the object to be dusted (such as a mattress, sofa, or carpet) until it taps the object, achieving the purpose of dust removal. After the cam mechanism 12 disengages from the tapping element 13, the tapping element 13 resets under the action of the reset mechanism 14 without being subjected to external force. Thus, as the drive mechanism continues to drive the drive shaft 11 to rotate, the tapping element 13 continuously taps the object to be dusted, removing dust, in cooperation with the cam mechanism 12 and the reset mechanism 14. The suction mechanism (not shown in the figure) absorbs the dust kicked up by the tapping element 13. The structure of the suction mechanism is not limited; for example, the suction mechanism includes a fan, which collects the dust using suction.

[0032] As described above, by continuously driving the drive shaft 11 to rotate, the drive shaft 11 drives the cam mechanism 12, and the cam mechanism 12 pushes the beater 13 to continuously beat the dust removal object, which can efficiently and effectively raise the dust. The raised dust will maintain a certain height due to inertia and be smoothly sucked in by the suction mechanism. In the end, the dust removal problem of the object is solved more efficiently and effectively, the cleaning power is stronger, and the object is cleaned more thoroughly.

[0033] Of course, based on the function of the cam mechanism 12, the components included in the cam mechanism 12 are not limited, as long as they can achieve the stated function. The cam structure 12 used in this application is described below.

[0034] See Figure 3 , Figure 5 and Figure 6 and combined Figure 2 and Figure 4 The cam mechanism 12 is a cam. The structure of the cam is not limited, as long as it can realize the tapping function. The tapping mechanism 1 includes multiple cams and multiple tapping elements 13. Each cam corresponds to one tapping element 13.

[0035] The plurality of said cams are positioned on the drive shaft and are circumferentially offset from the drive shaft. In some embodiments, some of the cams are offset along the circumference of the drive shaft 11, such as... Figure 5 and Figure 6All cams are arranged axially along the drive shaft 11, with cams in the same row not staggered and cams in adjacent rows staggered. In other embodiments, all cams are staggered. The staggered angle is not limited to 180 degrees as shown in the figure (described later), but can also be staggered by 30 degrees, 60 degrees, 90 degrees, etc., so that during the rotation of the drive shaft 11, some of the tapping members 13 tap the dust removal object, while others do not tap the dust removal object.

[0036] As described above, since the cam mechanism 12 is a cam, the structure of the dust removal device is simple. Each cam corresponds one-to-one with the tapping element 13, allowing each tapping element 13 to tap a small area. This small-area tapping ensures sufficient tapping force, resulting in strong cleaning power and efficient, effective cleaning. Furthermore, the area tapped by all the tapping elements 13 covers a large area of ​​the dust-removing object, ultimately ensuring efficient and effective cleaning of the dust-removing object.

[0037] See Figure 5 , Figure 6 and Figure 3 The drive shaft 11 includes two opposite sides, each side having a cam. For example... Figure 5 and Figure 6 As shown, after setting cams on each side, additional cams are added, with the cams spaced apart, so that the drive shaft has two rows of symmetrical cams. Of course, the number of cams on both sides can be equal or unequal. In some embodiments, there can also be three rows, four rows, etc.

[0038] See Figure 5 and Figure 6 and combined Figure 2 , Figure 3 and Figure 4 The following describes one embodiment of the aforementioned cam configuration on each side: There are five cams in total. From left to right, the first, third, and fifth cams are located on the first side of the drive shaft 11, arranged in the first row, all vertically downwards, as shown by arrow A. The second and fourth cams are located on the second side, symmetrical to the first side, arranged in the second row, all vertically upwards, as shown by arrow a. The vertical upward and vertical downward angles are 180 degrees. Based on the subsequent description of the function of this 180-degree angle, those skilled in the art will understand that the 180 degrees is not limited to a precise 180 degrees; any angle sufficient to achieve the subsequent function is acceptable.

[0039] As described above, since each of the symmetrical sides has a cam, when the object to be dusted is being tapped, the cam is in the vertical direction. When the object to be dusted is not being tapped, all the cams (cam mechanism 12) can rotate to the horizontal direction without applying force to the tapping element 13. Under the action of the reset mechanism 14, the tapping element 13 moves away from the object to be cleaned. In this way, for objects that are not to be cleaned (for example, the cleaning area does not have carpet), the tapping element 13 is prevented from interfering with other objects. For cleaning, this arrangement allows the cam to move a large stroke, resulting in greater cleaning force and more efficient and effective cleaning of the object to be dusted, making the object to be dusted cleaner.

[0040] See Figure 4 and combined Figure 2 and Figure 3 The dust removal device includes a limiting mechanism 15, which limits the beating member 13 to allow it to move linearly. Based on the subsequent function of the limiting mechanism 15, the limiting mechanism 15 is not limited to the structure shown in the figure; it only needs to achieve the aforementioned function.

[0041] As described above, by limiting the tapping component 13 through the limiting mechanism 15, it is more likely that the tapping component 13 can perform the tapping function, thereby solving the dust removal problem of the dust removal object more efficiently and effectively, with stronger cleaning power and the dust removal object being cleaned more thoroughly.

[0042] See Figure 4 and combined Figure 1 and Figure 2 The dust removal device includes a housing 17. In embodiments of this application, the housing 17 includes a base 171 and a top cover 172, etc. The limiting mechanism 15 is a limiting hole disposed on the housing 17. The limiting hole can be a through hole as shown in the figure; in some embodiments, it can also be a hole of various shapes such as a notch, as long as it can achieve the limiting function. Figure 4 and Figure 3 It is understood that each of the tapping members 13 extends out of a corresponding limiting hole (limiting mechanism 15) so as to abut against the corresponding cam mechanism 12 (cam). That is, when the cam moves to this position, it can push the cam towards the dust removal object.

[0043] As described above, since the limiting mechanism 15 is a limiting hole set in the housing 17, the structure of the limiting mechanism is simpler while ensuring the linear movement of the tapping member 13 to achieve a more efficient and effective solution to the dust removal problem of the object, stronger cleaning force, and cleaner dust removal object.

[0044] See Figure 7 and Figure 5The striking member 13 includes a pushing part 131 and a striking part 132 that are pushed by the cam mechanism 12. The striking part 132 is symmetrically arranged with respect to the pushing part 131. That is, the pushing part 131 can be considered as the axis of symmetry of the striking part 132. In this case, the striking part 132 can... Figure 7 There could be only one, or there could be two.

[0045] See Figure 6 Each of the reset mechanisms 14 includes two reset members 141, which are symmetrically arranged relative to the pushing part 131. Of course, in some other embodiments, there may be only one reset member.

[0046] As described above, since the two reset members 141 are symmetrically arranged relative to the pushing part 131, the force borne by the tapping part 132 is balanced, for example, there will be no tilting state. Thus, the dust removal problem of the dust removal object is solved more efficiently and effectively, the cleaning power is stronger, and the dust removal object is cleaned more thoroughly. Under the premise that the structure of the limiting mechanism is simpler.

[0047] See Figure 6 and combined Figure 1 , Figure 2 and Figure 4 The dust removal device includes a connecting part. The reset member 141 is a spring, and one end of the spring is connected to the striking part 132 (e.g., Figure 6 As shown in the figure, the other end is connected to the connecting part. The connecting part can be connected to any component or part of the dust removal device (such as the housing 17), as long as it can realize the resetting function of the resetting component. Although the figure does not explicitly show how it is connected to the housing, technicians can infer the connection based on the provided information. Figure 1 and Figure 2 The positional relationship between the striking component 13 and the housing 17 clearly indicates how the other end is connected to the housing 17. The specific location of the connection to the housing 17 is not limited; in this embodiment, the other end of the spring is connected to the base 171.

[0048] As described above, since the reset member 141 is a spring, and the aforementioned cam mechanism 12 is a cam and / or the limiting mechanism 15 is a limiting hole, the structure of the dust removal device is simple.

[0049] In some implementations, see Figure 7 The tapping member 13 includes a contact surface 1321. In this application, the tapping part 132 includes the contact surface 1321. The contact surface 1321 is used to contact the dust removal object and is provided with a plurality of protrusions 1322.

[0050] As described above, the presence of multiple protrusions 1322 increases the roughness of the contact surface, thereby enhancing friction. When the tapping member 13 taps the surface of the object being cleaned, these protrusions 1322 more effectively grasp and remove dust particles. Furthermore, the slight physical impact generated when the protrusions 132 contact the object helps loosen tightly adhered dust particles, allowing them to separate from the object's surface. In summary, the protrusions 1322 result in stronger cleaning power and a cleaner object.

[0051] See Figure 1 The dust removal device includes a housing 17, the bottom of which includes a connecting port 173. The air duct 174 of the dust collection mechanism communicates with the connecting port 173. The forward direction of the dust removal device is taken as a reference. The forward direction is as follows... Figure 1 As indicated by the middle arrow F. In combination Figure 3 The base 171 includes a roller brush 175 located at the connection port 173. An air duct 174 is located behind the roller brush 175. The tapping member 13 is located in front of the connection port 173.

[0052] As described above, the flapping element 13 is located in front of the connecting port 173, and the air duct 174 is connected to the connecting port 173. In this way, the dust kicked up by the flapping element 13 can be more easily sucked into the vacuuming mechanism.

[0053] In some embodiments, the drive mechanism includes a motor that drives the drive shaft to rotate in the same direction during operation. As described above, the motor rotates in the same direction, for example, continuously rotating clockwise or continuously rotating counterclockwise during operation. This reduces the performance requirements on the motor compared to a motor that can rotate both clockwise and counterclockwise.

[0054] Secondly, this application discloses a sweeping machine. The sweeping machine includes an identifier and any of the aforementioned dust removal devices. The identifier 18 is used to identify the object to be dusted. With reference to the forward direction of the sweeping machine, the identifier 18 is disposed in the housing 17 of the dust removal device and is also located in front of the beater 13. The structure of the identifier 18 is not limited, as long as it can identify the object to be dusted; for example, an identifier using ultrasonic waves. With reference to the forward direction of the dust removal device, the identifier 18 is located in front of the beater 13. As described above, by setting the identifier 18, the beater mechanism 1 is activated to perform dust removal only when a dust object is identified, resulting in low power consumption of the dust removal device. In some embodiments, the sweeping machine includes a base station. When cleaning is not required, the dust removal device is located inside the base station; when cleaning is required, the dust removal device leaves the base station. Of course, the structure of the sweeping machine is not limited, as long as it includes the dust removal device.

[0055] Thirdly, this application also discloses a vacuum cleaner. The vacuum cleaner includes any of the aforementioned dust removal devices.

[0056] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
